Description

Technical Field

[0001] The invention relates to the field of vacuum bag film processing equipment, in particular to vacuum bag film production and processing equipment. Background Art

[0002] Vacuum bagging film usually refers to a film material used in vacuum packaging systems, which can form and maintain a vacuum state under certain environmental conditions. The basic function of vacuum bagging film is to form a vacuum system and provide good coverage. In modern packaging technology, vacuum bagging films are also widely used as packaging materials in the fields of food, electronics, etc. They provide high barrier properties, can effectively extend the shelf life of products, and protect products from damage by the external environment.

[0003] In the production process of vacuum bag film, the plastic particles for making the vacuum bag film need to be crushed first, and then go through processes such as hot melting, roller forming, cooling and shaping, and finally a vacuum bag film with excellent properties and uniform texture is obtained. In the existing processing process, the roller crushing method is usually used to crush the plastic particles for subsequent processing. This method has the advantages of fast crushing speed and continuous operation, but in actual use, it is difficult to ensure that all plastic particles are fully crushed, which will cause uneven melting of the plastic particles in the subsequent hot melting process, and ultimately affect the quality of the vacuum bag film.

[0004] A Chinese patent with authorization announcement number CN116673088A discloses a vacuum bag film production and processing device and process, including a crushing box, the inner wall of which is rotatably connected to two crushing rollers, the outer wall of which is fixedly connected to two first motors, the output end of the first motor is fixedly connected to the crushing rollers, and also includes: a re-crushing structure respectively arranged on the inner wall of the crushing box, for screening and secondary crushing of the crushed raw material particles. By setting up the re-crushing structure, the raw material particles are screened with the help of a screening plate, and the raw material particles with qualified volume will fall through the screening plate, while the raw material particles with larger volume will slide into the storage box, and the storage box is reciprocated in the vertical direction with the help of a bidirectional screw rod. When the storage box slides to a certain position, the raw material particles will be poured out, so that the raw material particles are secondary crushed by the crushing rollers, thereby ensuring that the raw material particles can be evenly melted.

[0005] However, the above patent still has the following disadvantages:

[0006] 1. In actual use, the above patent cannot effectively improve the crushing effect, and thus cannot reduce the amount of plastic particles that are not fully crushed. After a long period of continuous processing, more and more plastic particles are re-transported to the crushing roller, which will squeeze out the crushing efficiency of the plastic particles that have just been put into the equipment and are being crushed at the same time, and ultimately affect the processing efficiency.

[0007] 2. The above patent controls the storage box to move up and down reciprocatingly, and puts the insufficiently crushed plastic back into the crushing rollers for secondary crushing, and uses an air pump to generate airflow to assist the crushed plastic particles to pass through the sieve plate to improve the screening efficiency. However, in actual use, this method has low work efficiency, will cause waste of electricity, and has a relatively complex structure, making it difficult to ensure continuous and stable long-term operation.

[0008] 3. In actual use, plastic particles themselves have a certain ability to resist plastic deformation. When rolling, some plastic particles will be squeezed and splashed to the outside of the equipment. These plastic particles splashed to the outside of the equipment will be mixed with dust. Even if they are collected, they cannot be directly used, resulting in waste. Especially after long-term continuous use, the amount of wasted plastic particles cannot be underestimated. Summary of the invention

[0009] In order to overcome the shortcomings of the prior art, the present invention solves the technical problem of improving the crushing effect of plastic particles, crushing the plastic particles more comprehensively, reducing the number of plastic particles that are not fully crushed, lifting the plastic particles that are not fully crushed and crushing them again, thereby improving the crushing effect and at the same time improving the screening efficiency of the crushed plastic particles, thereby improving the production efficiency of the vacuum bag film, and directly utilizing the power of the rotation of the pressure roller without consuming external energy, reducing power consumption and thus reducing the cost of use, and by providing an anti-splash component, preventing plastic particles from splashing outside the equipment, thereby avoiding a large amount of raw material waste during long-term operation.

[0010] In order to achieve the above object, the present invention provides the following technical solutions, including:

[0011] A lower shell, two cover plates are fixedly connected on both sides of the lower shell, two rotating shafts are rotatably connected between the two cover plates, and pressure rollers are fixedly connected to the two rotating shafts;

[0012] An upper shell, wherein an anti-splash component is arranged in the upper shell;

[0014] A group of seals are fixedly connected at both sides of each slide slot opening. Each group of seals fits tightly with the corresponding surface of the paddle and slides relatively. Each seal is made of wear-resistant material and is fixed to both sides of the paddle opening by hidden bolts.

[0015] Two side arc panels are fixedly connected to the lower shell at both sides of the two pressure rollers, and a filter plate is fixedly connected between the bottom ends of the two side arc panels. A plurality of filter holes are evenly distributed on the filter plate.

[0016] Each of the paddles can fit closely with the surface of the filter plate and slide relatively thereto, and an axial direction of each filter hole and a moving direction of the corresponding paddle are arranged at an acute angle.

[0017] The arc surface on the inner side of each side arc panel can smoothly transition and connect with the contour of the filter plate, the end of each paddle plate can fit closely and slide relatively with the surface of the filter plate and the inner arc surface of the side arc panel, the gap between each pressure roller and the corresponding part of the filter plate gradually decreases along the moving direction of the paddle plate, and the gap between each pressure roller and the corresponding side arc panel gradually increases along the moving direction of the paddle plate.

[0018] A guide plate is fixedly connected to the inner side of each cover plate at a position corresponding to each pressure roller, a guide groove is provided on a side of each guide plate close to the pressure roller, and protruding sliding pins are provided at both ends of each shift plate, and each sliding pin is slidably connected to the corresponding guide groove.

[0019] A plurality of reinforcing ribs are evenly distributed and fixedly connected in the lower shell below the filter plate, and each of the reinforcing ribs can bear the filter hole.

[0020] The ends of the two rotating shafts extending out of the cover plate are respectively fixedly connected with two symmetrical worm gears, and the outer side of the cover plate close to the worm gear is fixedly connected with an end cover covering the two worm gears, and a transmission rod is rotatably connected inside the end cover, and two symmetrical worms are fixedly connected to the transmission rod at the corresponding positions of the two worm gears, and each of the worms is meshed and driven with the corresponding worm gear.

[0021] A motor frame is fixedly connected to one side of the lower shell, a motor is fixedly connected to the outer side of the motor frame, and a power output end of the motor passes through the motor frame and is drivingly connected to an end of a transmission rod extending out of an end cover.

[0025] (2) The teeth are scraped on the filter plate and work together with the edge of the filter hole to apply shear force to the plastic particles that are not fully crushed, and the plastic particles are crushed again, further improving the crushing effect and efficiency.

[0026] (3) The filter plate is scraped by the teeth, and the gap between the filter plate and the crushing roller is gradually reduced, so that the plastic particles falling on the filter plate are squeezed during the movement of the teeth, thereby improving the screening efficiency. The larger plastic particles will eventually rotate with the teeth to the top of the crushing roller and be crushed again. This process is achieved only by the rotation of the crushing roller without external energy consumption, thus achieving the effect of saving energy and reducing the cost of use.

[0027] (4) When the teeth are meshed and conveying the plastic particles, a tortuous space is formed, which makes it difficult for the plastic particles to splash. By setting an anti-splashing component at the feed inlet, the splashing of the plastic particles is further avoided, thereby reducing the waste of raw materials generated during continuous long-term crushing processing.

DETAILED DESCRIPTION

[0037] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0038] Embodiment 1:

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, a vacuum bag film production and processing equipment includes a lower shell 10, a bracket 11 is fixedly connected to the outer side of the lower shell 10, an upper shell 12 is fixedly connected to the top of the lower shell 10, a feed port 36 is opened at the top of the upper shell 12, and a discharge port 37 is opened at the bottom of the lower shell 10, two cover plates 29 are symmetrically distributed and fixedly connected on both sides of the lower shell 10, two rotating shafts 16 are rotatably connected between the two cover plates 29, and two pressing rollers 17 close to each other are fixedly connected to the two rotating shafts 16 respectively, and two side arc panels 22 are symmetrically distributed and fixedly connected on the inner side of the lower shell 10 at both sides of the two pressing rollers 17, a filter plate 23 is fixedly connected between the two side arc panels 22 and below the two pressing rollers 17, and a plurality of filter holes 24 are evenly distributed on the filter plate 23.

[0040] By setting the pressing roller 17, the plastic particles used as the raw material of the vacuum bag film can be crushed and crushed, and continuous long-term crushing work can be achieved. The crushed plastic particles are screened by the filter plate 23 to ensure that the fully crushed plastic particles pass through and are subsequently processed to ensure production quality.

[0041] like Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, a group of slide grooves 18 are evenly distributed on the surface of each pressure roller 17, and a paddle plate 19 is slidably connected in each slide groove 18. The two groups of paddle plates 19 corresponding to the two pressure rollers 17 are arranged alternately with each other, and the end of each paddle plate 19 can fit closely with the surface of the filter plate 23 and the inner arc surface of the corresponding side arc panel 22 and slide relatively.

[0042] By setting the paddle 19, the plastic particles can be pushed into between the two pressure rollers 17 for crushing and crushing during the rotation of the pressure rollers 17, thereby ensuring that the plastic particles can be squeezed and crushed by the crushing rollers more comprehensively, improving the crushing effect of the plastic particles, reducing the number of plastic particles that are not fully crushed, and being able to limit the plastic particles, effectively reducing the probability of splashing of the plastic particles during crushing.

[0043] In addition, the paddle plate 19 rotates with the pressure roller 17, and the plastic particles that are retained on the surface of the filter plate 23 and are not fully crushed are transported upward again until they re-enter between the two pressure rollers 17 for crushing again, thereby ensuring the crushing effect of the plastic particles and the production quality of the vacuum bag film. Compared with the prior art, the power for lifting the plastic particles for secondary crushing comes directly from the rotation of the pressure roller 17, without external energy consumption, thereby achieving the effect of saving energy and reducing the use cost.

[0044] like Figure 5 and Figure 6 As shown, the axial direction of each filter hole 24 is set at an acute angle to the moving direction of the corresponding dial plate 19, the arc surface on the inner side of each side arc panel 22 can smoothly transition and connect with the contour of the filter plate 23, the gap between each pressure roller 17 and the corresponding part of the filter plate 23 gradually decreases along the moving direction of the dial plate 19, and the gap between each pressure roller 17 and the corresponding side arc panel 22 gradually increases along the moving direction of the dial plate 19, and a plurality of reinforcing ribs 28 are evenly distributed and fixedly connected below the filter plate 23 in the lower shell 10, and each reinforcing rib 28 can support the filter hole 24.

[0045] By setting the inclined filter holes 24, when the paddle 19 pushes the insufficiently crushed plastic particles, the filter holes 24 and the paddle 19 can work together to apply shear force to the plastic particles, thereby further crushing the plastic particles, reducing the number of insufficiently crushed plastic particles, and avoiding the plastic particles that undergo secondary crushing from excessively crowding out the efficiency of crushing new plastic particles.

[0046] In addition, by gradually reducing the gap between the pressure roller 17 and the filter plate 23, the paddle plate 19 gradually applies extrusion force to the plastic particles on the surface of the filter plate 23 during the process of pushing the plastic particles, thereby accelerating the plastic particles to pass through the filter holes 24, improving the screening efficiency and thus improving the production and processing efficiency.

[0047] like Figure 5 and Figure 6 As shown, a group of seals 20 are fixedly connected to both sides of the opening of each slide groove 18. Each group of seals 20 is made of wear-resistant material. In this embodiment, Teflon material is specially selected. Each group of seals 20 fits tightly with the surface of the paddle 19 and slides relatively. Each seal 20 is fixed to the pressure roller 17 by a group of hidden bolts 21.

[0048] By providing the seal 20, the friction between the paddle 19 and the pressure roller 17 can be effectively reduced, the wear of parts can be reduced, and the service life of the equipment can be increased. By providing the hidden bolts 21, the outer surface of the pressure roller 17 can be smooth and flat while effectively fixing the seal 20, thereby ensuring that the plastic particles can be evenly and fully crushed.

[0049] like Figure 6 , Figure 7 and Figure 8 As shown, on the inner side of the two cover plates 29, a guide plate 25 is fixedly connected at the corresponding position of each pressure roller 17, and each guide plate 25 is provided with a guide groove 26, each guide groove 26 is arranged according to the moving trajectory of the shift plate 19, and each shift plate 19 is provided with a sliding pin 27 at both ends, and each sliding pin 27 is slidably connected to the corresponding guide groove 26.

[0050] By providing the guide plate 25 and the guide groove 26, the extension and retraction of the paddle plate 19 can be guided and controlled during the rotation of the paddle plate 19 with the pressure roller 17, so that the paddle plate 19 can stably fit the surface of the filter plate 23 and the side arc panel 22 and move, and when the paddle plate 19 is close to the area where the two pressure rollers 17 are crushing, the paddle plate 19 can be controlled to fully retract, so that the surface of the pressure rollers 17 in the crushing area is smooth and flat, thereby ensuring the crushing effect.

[0051] like Figure 3 , Figure 4 and Figure 8 As shown, two inward-converging side guide plates 15 are symmetrically distributed and fixedly connected on both sides of the upper shell 12, a pointed guide plate 13 is fixedly connected at the center of the upper shell 12, and soft curtains 14 are fixedly connected at both ends of the bottom of the pointed guide plate 13, and the lower edge of each soft curtain 14 naturally hangs down on the surface of the side guide plate 15.

[0052] By providing the pointed material guide plate 13 and the side material guide plate 15, a tortuous space can be formed, which can effectively reduce the problem of plastic particles splashing out of the equipment without affecting the feeding, thereby reducing the waste of raw materials. By providing the soft curtain 14, the gap between the pointed material guide plate 13 and the side material guide plate 15 can be further blocked, which will not affect the normal feeding and directly isolate a small amount of plastic particles from splashing out of the equipment, completely eliminating the problem of waste caused by splashing of raw materials.

[0053] like Figure 1 and Figure 8As shown, the ends of the two rotating shafts 16 extending out of the cover plate 29 are respectively fixedly connected with two symmetrical worm gears 31, and the cover plate 29 close to the worm gears 31 is fixedly connected with an end cover 30 covering the two worm gears 31, and a transmission rod 33 is rotatably connected inside the end cover 30, and two symmetrical worms 32 are respectively fixedly connected to the transmission rod 33 at the corresponding positions of the two worm gears 31, and the thread directions of the two worm gears 32 are opposite, and a motor frame 34 is fixedly connected to the outer side of the lower shell 10, and a motor 35 is fixedly connected to the motor frame 34, and the power output end of the motor 35 passes through the motor frame 34 and is drivingly connected to the end of the transmission rod 33 extending out of the end cover 30.

[0054] By providing the worm wheel 31 and the worm 32 , the two pressure rollers 17 can be driven to rotate stably, and the two worms 32 have opposite spiral directions, so that the two pressure rollers 17 can achieve synchronous opposite rotation, and the two sets of shift plates 19 always maintain a staggered state without affecting each other.

[0055] In this embodiment, initially, the operator connects the device to a power source and starts the motor 35 through the control system. The transmission connection between the worm gear 31 and the worm 32 is then used to drive the two pressing rollers 17 to rotate synchronously in opposite directions. Then, the operator continuously feeds the plastic particles to be processed into the device from the feed port 36 for crushing.

[0056] When plastic particles enter the equipment, they are first guided and diverted to both sides by the pointed guide plate 13. After falling into the side guide plate 15, a large number of plastic particles continue to slide along the side guide plate 15, pushing the soft curtain 14 through the gap between the pointed guide plate 13 and the side guide plate 15, and finally falling between the two pressure rollers 17.

[0057] At the same time, the two pressure rollers 17 rotate relative to each other and the paddle 19 is in an extended state above the pressure rollers 17, then the paddle 19 rotates together with the pressure rollers 17, and the plastic particles are pushed and gathered between the two pressure rollers 17, so that the plastic particles stably enter the crushing area for crushing and crushing, thereby improving the crushing effect and crushing efficiency of the plastic particles.

[0058] Furthermore, a plurality of mutually staggered shifting plates 19 form a tortuous space, which effectively restricts the plastic particles and reduces the probability of splashing of the plastic particles when being squeezed.

[0059] Even if a small amount of plastic particles are squeezed and splashed, since the soft curtain 14 directly isolates the gap between the pointed guide plate 13 and the side guide plate 15, the kinetic energy of the splashed plastic particles is also small. When the splashed plastic particles hit the soft curtain 14, it is difficult to push the soft curtain 14 to fall back between the two pressure rollers 17. Therefore, during long-term continuous working, the problem of raw material waste caused by the splashing of plastic particles is completely eliminated.

[0060] At the same time, when the plastic particles enter between the two pressure rollers 17 for crushing, the paddle 19 in the crushing area retracts into the slide groove 18 under the guidance of the guide groove 26, so that the surface of the pressure roller 17 in the crushing area is smooth and flat, thereby ensuring the crushing effect.

[0061] Subsequently, the crushed plastic particles fall on the surface of the filter plate 23, and the paddle plate 19 gradually extends out of the slide groove 18 under the guidance of the guide groove 26 and slides in contact with the surface of the filter plate 23. The crushed plastic particles are pushed by the paddle plate 19 and move toward the two side arc panels 22 respectively. In this process, the fully crushed plastic particles directly pass through the filter holes 24, fall continuously from the discharge port 37, and are uniformly collected to facilitate subsequent processing.

[0062] The incompletely crushed plastic particles will get stuck at the opening of the filter hole 24. At this time, the paddle 19 rotates with the pressure roller 17 and works together with the inclined filter hole 24 to apply a shear force to the incompletely crushed filter hole 24, thereby shearing and crushing the incompletely crushed plastic particles, allowing them to pass through the filter hole 24 smoothly, reducing the number of incompletely crushed plastic particles.

[0063] During the screening process of plastic particles, when there are fewer plastic particles, the screening efficiency is not greatly affected. However, when there are more plastic particles, for example, when the plastic particles fill the gap between the pressure roller 17 and the filter plate 23, since the gap between the pressure roller 17 and the filter plate 23 gradually decreases, and the paddle 19 is guided by the guide groove 26 to always fit the surface of the filter plate 23, when the paddle 19 pushes the plastic particles to move, the plastic particles between the pressure roller 17 and the filter plate 23 are squeezed, thereby increasing the probability of the plastic particles passing through the filter holes 24, thereby improving the screening efficiency and thus ensuring the production and processing efficiency.

[0064] Subsequently, a small amount of incompletely crushed plastic particles remain on the filter plate 23, and these plastic particles continue to be lifted upward into the range of the side arc panel 22 as the paddle plate 19 is pushed. During this process, the paddle plate 19 is guided by the guide groove 26 to always fit the side arc panel 22 to prevent the plastic particles from falling back. Finally, the paddle plate 19 returns to the extended state, and the plastic particles are lifted by the paddle plate 19 and finally enter between the two pressure rollers 17 again to be crushed again, thereby ensuring the crushing effect and thus ensuring the production quality of the vacuum bag film.

[0065] Embodiment 2:

[0066] A vibration component is provided in the lower shell 10 close to the filter plate 23. When screening, the filter plate 23 is vibrated at a high frequency by the vibration component, which improves the screening efficiency and reduces the probability of plastic particles clogging the filter holes 24, thereby ensuring stable operation of the equipment.

[0067] The motor 35 and the bearing sleeved on the rotating shaft 16 are mature existing technologies and will not be described in detail herein.

[0068] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0069] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the product or system including the elements.

[0070] The above description shows and describes several preferred embodiments of the present application, but as mentioned above, it should be understood that the present application is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the application concept described herein through the above teachings or the technology or knowledge of the relevant field.
