Description

Technical Field

[0001] This utility model belongs to the field of thermoforming technology, specifically relating to a waste discharge device for a hot plate machine. Background Technology

[0002] The market for disposable consumer products is growing, and packaging methods are becoming increasingly widespread. To accommodate different products, different sizes and shapes have been developed. To better fit the shape of the products produced by companies and maximize the use of internal space to hold the products, as well as to pack more products in a limited space, packaging boxes are becoming increasingly customized.

[0003] Because the production of customized packaging boxes involves heating sheet material to melt it, then forming it using positive and negative pressure thermoforming technology, followed by punching, and finally exporting the finished product, the remaining hollowed-out scrap sheet after the product is exported needs to be collected and recycled. In existing technology, scrap is generally collected by continuously rotating rollers. However, since the product's discharge direction is often adapted to its subsequent production processes or limited by workshop space, it may discharge in different directions. If scrap recycling is always at the end of the frame, it will inevitably obstruct the product's discharge direction. If the rotating rollers are aligned with the product's discharge direction, exporting the collected scrap in rolls will also be relatively troublesome. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a waste discharge device for a hot plate machine. The discharge assembly consists of a guide roller and two sets of discharge rollers connected end to end in a triangular structure. Therefore, when the waste plate is being guided, it can be discharged directly from the guide roller alone or from the two sets of discharge rollers, so that the waste plate has three selectable discharge directions, realizing flexible material collection.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A waste discharge device for a hot plate mill includes a frame, a feeding assembly, a discharge assembly, and a receiving assembly. The feeding assembly includes a fixed plate, a driven roller, a driving roller, and a motor. The fixed plate is connected to the frame. Both the driven roller and the driving roller are rotatably connected to the fixed plate. The motor is mounted on the fixed plate, and its output drives the driving roller to rotate. The discharge assembly consists of a guide roller and two sets of discharge rollers connected end-to-end in a triangular structure on the frame. The waste plate held between the driven roller and the driving roller passes through the guide roller and the discharge roller sequentially before entering the receiving assembly.

[0006] The feeding assembly also includes a movable plate and a feeding cylinder. The lower end of the fixed plate is provided with a downward-facing slot. The movable plate is movably connected to the slot. The feeding cylinder is located at the opening of the slot. The drive roller is rotatably connected to the movable plate. The drive roller can abut against the driven roller under the drive of the feeding cylinder.

[0007] It also includes a guiding assembly, which includes a guiding rod and a guiding roller. One end of the guiding rod is connected to a fixed plate, and the other end of the guiding rod is rotatably connected to the guiding roller. The waste plate first passes through the guiding roller and then enters between the driven roller and the driving roller. The guiding assembly also includes a guiding cylinder, which is connected to the frame. The end of the guiding rod connected to the fixed plate is rotatably connected, and the output end of the guiding cylinder is connected to the middle of the guiding rod.

[0008] The waste discharge device of the hot plate mill with this structure requires a driving force to discharge the hollow waste plate from the cutting assembly. Therefore, a feeding assembly is installed that clamps the waste plate between a driven roller and a driving roller, and drives the rotation of the driving roller via a motor, thus transporting the waste plate towards the discharge assembly. In daily production, if the distance between the driven roller and the driving roller remains constant, it is difficult to accommodate all sizes of waste plates. If the contact is not tight enough, the waste plate cannot be discharged; if the contact is too tight... This would also cause accelerated damage between the driven roller and the driving roller. In order to facilitate better operation for workers, a groove is set at the bottom of the fixed plate. A movable plate is movably connected in the groove. The driving roller is rotatably connected to the movable plate, and the movable plate is driven by the feeding cylinder to move up and down. Therefore, under the drive of the feeding cylinder, the driving roller can flexibly move up and down, adjust the gap between it and the driven roller, so that the distance can be adjusted to the most suitable distance during the conveying of the waste plate, thereby ensuring the stability of the conveying and extending the service life of the driven roller and the driving roller.

[0009] The discharge assembly consists of a guide roller and two sets of discharge rollers connected end-to-end in a triangular structure on the frame. The axis of the guide roller is parallel to the axis of the drive roller. Therefore, when the waste plate is discharged from the guide roller, its discharge direction is consistent with the production direction. When it is necessary to discharge the waste plate from the left and right ends, the waste plate can be discharged from the guide roller and then wound around the discharge rollers at the left and right ends, thereby changing the guiding direction of the waste plate. This allows the receiving assembly to be flexibly set in three directions at the discharge end. This structure only adds two sets of discharge rollers to form a triangular structure, thereby adding two discharge directions. The investment cost is low, but the effect of use is more flexible.

[0010] During the waste plate unloading process, it's inevitable that the receiving assembly will accumulate too much material, requiring a roller change. This roller change necessitates stopping the equipment. Since the waste plate has inertia during transmission, without any structural intervention, excessive material will remain between the cutting and feeding assemblies. When workers change rollers on the receiving assembly and restart the machine, this excess material can cause knots or tears in the waste plate, affecting subsequent material collection. To avoid this, the cutting and feeding assemblies... A guiding assembly is added between the components, which rotatably connects to the guide rod on the fixed plate. The other end of the guide rod is rotatably connected to the guide roller. The middle of the guide rod is connected to the output end of the guide cylinder. Therefore, when the equipment stops, the guide cylinder is activated to slowly retract, which can lift the guide roller. This allows any excess material remaining on the waste plate to be pulled on the guide roller, so that the waste plate remains taut even when the machine is stopped. When the equipment is started, the guide cylinder is slowly extended, allowing the remaining material to be released slowly and the material to be collected, thus preventing the waste plate from knotting or breaking.

[0011] Furthermore, the guide roller consists of a rotating plate and several rotating rollers. The rotating plate is rotatably connected to the guide rod, and the several rotating rollers are arranged in a circumferential array on the edge of the rotating plate.

[0012] Compared with the prior art, the advantages of this utility model are as follows: the active roller can flexibly move up and down, and adjust the gap between it and the driven roller, so that the distance can be adjusted to the most suitable distance during the waste plate conveying process, thereby ensuring the stability of the conveying and extending the service life of the driven roller and the active roller. The guide roller with a triangular structure and two sets of discharge rollers are connected end to end. This structure only adds two sets of discharge rollers to form a triangular structure, thereby adding two discharge directions. The investment cost is low, but the effect of use is more flexible. The setting of the guide roller can make the excess material left on the waste plate be pulled on the guide roller, so that the waste plate is still in a taut state even when the machine is stopped. When the equipment is started, the guide cylinder slowly extends, so that the remaining excess material can be slowly released and the material is collected, thereby avoiding the waste plate from knotting or breaking.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] The specific embodiments of this utility model will now be described with reference to the accompanying drawings: like Figure 1-5 As shown, a waste discharge device for a hot plate mill includes a frame 1, a feeding assembly 2, a discharge assembly 3, and a receiving assembly. The feeding assembly 2 includes a fixed plate 21, a driven roller 22, a driving roller 23, and a motor 24. The fixed plate 21 is connected to the frame 1. The driven roller 22 and the driving roller 23 are rotatably connected to the fixed plate 21. The motor 24 is mounted on the fixed plate 21, and its output drives the driving roller 23 to rotate. The discharge assembly 3 is connected to the frame 1 by a guide roller 31 and two sets of discharge rollers 32 connected end to end in a triangular structure. The waste plate held between the driven roller 22 and the driving roller 23 passes through the guide roller 31 and the discharge roller 32 in sequence and then enters the receiving assembly.

[0018] The feeding assembly 2 also includes a movable plate 25 and a feeding cylinder 26. The lower end of the fixed plate 21 is provided with a downward-facing slot 211. The movable plate 25 is movably connected in the slot 211. The feeding cylinder 26 is located at the opening of the slot 211. The drive roller 23 is rotatably connected to the movable plate 25. The drive roller 23 can abut against the driven roller 22 under the drive of the feeding cylinder 26.

[0019] It also includes a guiding assembly 4, which includes a guiding rod 41 and a guiding roller 42. One end of the guiding rod 41 is connected to the fixed plate 21, and the other end of the guiding rod 41 is rotatably connected to the guiding roller 42. The waste plate first passes through the guiding roller 42 and then enters between the driven roller 22 and the driving roller 23. The guiding assembly 4 also includes a guiding cylinder 43, which is connected to the frame 1. The end of the guiding rod 41 connected to the fixed plate 21 is rotatably connected, and the output end of the guiding cylinder 43 is connected to the middle of the guiding rod 41.

[0020] Furthermore, the guide roller 42 is composed of a rotating plate 421 and a plurality of rotating rollers 422. The rotating plate 421 is rotatably connected to the guide rod 41, and the plurality of rotating rollers 422 are distributed in a circumferential array on the edge of the rotating plate 421.

[0021] Description of the working principle of this utility model: The waste discharge device of the hot plate mill with this structure requires a driving force to discharge the hollow waste plate from the cutting assembly. Therefore, the feeding assembly 2 clamps the waste plate between the driven roller 22 and the driving roller 23, and drives the rotation of the driving roller 23 through the motor 24, thereby transporting the waste plate towards the discharge assembly 3. In daily production, if the distance between the driven roller 22 and the driving roller 23 remains constant, it is difficult to accommodate all sizes of waste plates. If the contact is not tight enough, the waste plate will not be able to be discharged. If the contact is too tight, the driven roller 22 will be unable to discharge. To prevent accelerated damage between the driven roller 22 and the active roller 23, and also to facilitate better operation for workers, a slot 211 is provided at the bottom of the fixed plate 21. A movable plate 25 is movably connected in the slot 211, and the active roller 23 is rotatably connected to the movable plate 25. The movable plate 25 is driven to move up and down by the feeding cylinder 26. Therefore, under the drive of the feeding cylinder 26, the active roller 23 can flexibly move up and down, adjusting the gap between it and the driven roller 22. This allows the distance to be adjusted to the most suitable distance during the conveying of the waste plate, thereby ensuring the stability of the conveying and extending the service life of the driven roller 22 and the active roller 23.

[0022] The discharge assembly 3 is connected to the frame 1 in a triangular structure by a guide roller 31 and two sets of discharge rollers 32 connected end to end. The axis of the guide roller 31 is parallel to the axis of the drive roller 23. Therefore, when the waste plate is discharged from the guide roller 31, its discharge direction is consistent with the production direction. When the waste plate needs to be discharged from the left and right ends, it can be discharged from the guide roller 31 and then wound around the discharge rollers 32 at the left and right ends, thereby changing the guiding direction of the waste plate. This allows the receiving assembly to be flexibly set in three directions at the discharge end. This structure only adds two sets of discharge rollers 32 to form a triangular structure, thereby adding two discharge directions. The cost is low, but the effect of use is more flexible.

[0023] During the waste plate unloading process, it's inevitable that the receiving assembly will accumulate too much material, requiring a roller change. This roller change necessitates stopping the equipment. Since the waste plate has inertia during transmission, without any structural intervention, excessive material will remain between the cutting assembly and the feeding assembly 2. When workers change rollers on the receiving assembly and restart the machine, this excess material can cause knots or tears in the waste plate, affecting subsequent material collection. To prevent this, a guide assembly is added between the cutting assembly and the feeding assembly 2. 4. A guide rod 41 is rotatably connected to the fixed plate 21. A guide roller 42 is rotatably connected to the other end of the guide rod 41. The middle part of the guide rod 41 is connected through the output end of the guide cylinder 43. Therefore, when the equipment stops, the guide cylinder 43 is started to slowly retract, which can lift the guide roller 42, so that the excess material left on the waste plate is pulled on the guide roller 42, so that the waste plate is still in a taut state even when the equipment stops. When the equipment is started, the guide cylinder 43 is slowly extended, so that the remaining excess material can be slowly released and the material can be collected, thereby avoiding the waste plate from knotting or breaking.

[0024] To reduce the friction generated by the movement of the waste plate on the guide roller 42 between the cutting assembly and the feeding assembly 2, the guide roller 42 is composed of a rotating plate 421 and several rotating rollers 422. The rotating plate 421 is rotatably connected to the guide rod 41, and the several rotating rollers 422 are arranged in a circumferential array on the edge of the rotating plate 421. Therefore, during the process of the guide roller 42 guiding the waste plate, the waste plate is abutted by the rotating rollers 422, which can minimize the contact area and thus reduce the friction.

[0025] The beneficial effects of this utility model are as follows: the active roller 23 can flexibly move up and down, adjusting the gap between itself and the driven roller 22, so that the distance can be adjusted to the most suitable distance during the conveying of the waste plate, thereby ensuring the stability of the conveying and extending the service life of the driven roller 22 and the active roller 23. The triangular structure of the guide roller 31 and the two sets of discharge rollers 32 are connected end to end. This structure only adds two sets of discharge rollers 32 to form a triangular structure, thereby adding two discharge directions. The cost of investment is low, but the effect of use is more flexible. The setting of the guide roller 42 can make the excess material left on the waste plate be pulled on the guide roller 42, so that the waste plate is still in a taut state even when the machine is stopped. When the equipment is started, the guide cylinder 43 slowly extends, so that the remaining excess material can be slowly released and the material is collected, thereby avoiding the waste plate from knotting or breaking.

[0026] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
