Q:What is the delay time of the packer's cross sealing?

You can debug it yourself, set up a parameter, such as a delay of 1 second or a few seconds, look at the action of sealing, you know what time it is.

Q:What are the main plastic forming processes?

3. cold pressing molding. Cold pressing molding is also called cold pressing sintering molding. The difference between the cold press molding and the ordinary compression molding is that the material is pressurized and molded at room temperature. The mold after release can be heated or cured by chemical action. This method is used in the forming of polytetrafluoroethylene and some high temperature resistant plastics (such as polyimide, etc.). The general process is three steps of billet sintering cooling.4. transfer molding. Transfer molding is a molding process for thermosetting plastics. When molding, the mold is heated and softened in the heating chamber and then pressed into the mold cavity where it has been heated. According to the different types of transfer molding equipment form: trap type; the tank; the piston.The requirement of plastic molding for transfer molding is that the plastic should have a greater fluidity before reaching the curing temperature, and the curing rate must be faster at the curing temperature. Phenol, melamine, formaldehyde and epoxy resins can meet this requirement.Transfer molding has the following advantages: less waste edge products, can reduce the processing quantity; second molding with fine or brittle insert and perforation of the products, and can keep the insert and the hole position is correct; the product performance is uniform, accurate size, high quality; the mould wear small. The disadvantage is that the manufacturing cost is high compression mold die; the plastic loss; the fiber reinforced plastics for fiber orientation and anisotropy; and around the insert around the plastic, sometimes due to melting is not strong and make the products according to the strength reduction.

Q:What is the working principle of the pillow packing machine?

In fact, the special machine is often better than the packaging of the compatible machine. A packing machine should be packed in no more than 3-5 varieties. What's more, the products with the larger size and the difference in size should be packed separately as much as possible.

Q:How does the pulp solidify? What additives do you need? Curing agents? Or what do you need as binders?

(1) urea formaldehyde moulding powder;The resin powder of urea formaldehyde resin, commonly known as electric jade powder, is produced by wet process, such as tree ester, curing agent, filler, colorant, lubricant, stabilizer, plasticizer and so on1 Components(1) resin used for urea formaldehyde resin molding powder by condensation reaction degree is relatively shallow, the resin with low viscosity, easy dipping filler, and can ensure the long production cycle and drying after proper fluidity, condensate in the industrial use of urea and formaldehyde at low temperature (a mixture of dimethylol urea, urea and formaldehyde) are usually used. The ratio of 1:1.5 (molar ratio), the PH=8 (and temperature) 30 - 35 of all dissolved, adding urea oxalate was 0.3% - 0.33% and 0.88% - 0.54% of the oxalic acid, then the occurrence of exothermic reaction, temperature rise, temperature in 55 - 60 degrees, and strictly control the PH=5.5 - 6.5, 60 - 75min by urea formaldehyde resin is required. Because the condensation degree is low, in fact just over addition reaction, condensation reaction is mainly in the curing process.(2) the curing agent used in curing agent and pressing powder requires latent, usually oxalic acid, phthalic acid, two formic acid, benzoic acid, chloroacetic acid, etc.(3) packing material is the most commonly used pulp, followed by wood powder or inorganic fillers (glass fiber, asbestos, mica etc.). The pulp is wood as raw material, with sodium bisulfite, non soluble cellulose impurities to the wood, and then byThat is the pure cellulose bleaching. The amount of filler material for the total amount of 25%-32%, the amount is too small, the pressure of plastic powder fluidity big, product strength is low; on the contrary, the amount of excessive pressure, plastic powder fluidity decreases, the product surface is not smooth, water

Q:Which friend is an expert in mechanical equipment or a better understanding of sealing machines? Tell me how to identify the equipment

There are PLC control ah, if it is fully automatic, then ask the quality of sealing ah, it is best to let manufacturers give you a live demonstration, the soft power depends on the size of the factory, ah, after-sales service ah!

Q:Calendering, extrusion, blow molding, pressing, plastic (vacuum forming) and what is the rotational molding

Plastic forming and processing methodPlastic molding is an engineering technology, involves the plastic into all kinds of plastic products in the process. The transformation process tends to happen in one or more of the following conditions, such as polymer rheology and physical and chemical properties of the change.

Q:What kind of reducer is commonly used in packaging machinery?

There are many kinds of reducers used. What kind of machines are they under?

Q:What is a packaging machine?

Packaging machinery refers to the machinery that can complete all or part of the product and commodity packaging process. The packaging process includes filling, wrapping, sealing and other main processes

Q:What is the price of a small jujube packing machine?

Mainly see what some requirements, automatic metering packaging or vacuum packaging machine, after understanding can determine the price.

Q:Ask a mechanical problem, the waste film recycling in the packaging machinery is a new film packaging, after cutting, then use the roller to recycle the waste film. Encounter a

Is it settled?. Not really! It is not recommended to use torque as parameter control here. This is a tricky amount of control. And easy to fluctuate, prone to misoperation
