Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic production and processing technology, and in particular to a waste collection component for a plastic trimming machine. Background Technology
[0002] Due to their high chemical stability, relatively simple and efficient molding and processing, and low production cost, plastics are widely used in daily necessities and various industries. When cutting sheet plastics with a thickness of 3mm or less, a stamping-type cutting machine can be used for shaping. The operator needs to place the sheet plastic on the top of the lower mold embedded in the top of the worktable, and then activate the hydraulic telescopic cylinder or reciprocating drive mechanism to drive the upper mold to move down and collide with the lower mold, thus cutting the sheet plastic into the specified shape. The processing operation is simple and efficient, and the finished product has no burrs on the edges.
[0003] When cutting sheet plastic using existing stamping cutting machines, the operator manually places the plastic sheet to be cut between the upper and lower molds before starting the machine. After each cut, the operator adjusts the position of the plastic sheet and repeats the process until all parts of a plastic sheet have been cut. Then, the operator manually removes the waste material, discards it, and replaces it with a new sheet to repeat the process. This increases the workload of subsequent waste removal and is also quite dangerous. Utility Model Content
[0004] In view of this, the purpose of this utility model is to propose a waste collection component for a plastic trimming machine to solve the problem that manual feeding and material changing operations not only increase the workload of subsequent waste cleaning, but also pose a high risk of operation.
[0005] To achieve the above objectives, this utility model provides a waste collection assembly for a plastic trimming machine, comprising an loading platform and a unloading platform respectively disposed opposite to each other on both sides of a workbench. The waste collection assembly further includes:
[0006] Two side grooves are connected side by side between the top of the unloading platform and the loading platform, and a side belt conveyor for conveying plastic is provided in the side groove.
[0007] A central trough is located at the top of the unloading platform, and a central belt conveyor for auxiliary conveying of waste materials is installed inside the central trough.
[0008] A drive unit used to drive the central belt conveyor and the two side belt conveyors to operate synchronously.
[0009] Two horizontal support arms are arranged side by side outside the unloading platform, and an inclined guide plate is fixed between the two horizontal support arms.
[0010] A guide is arranged side by side between the loading platform and the unloading platform, the guide being used to constrain the direction of movement of the plastic during plastic loading and waste unloading.
[0011] Preferably, the guide includes a guide strip fixed between the top of the unloading platform and the top of the loading platform, a long groove is provided through the two vertical surfaces of the guide strip, and guide rollers are arranged in parallel and rotatable inside the long groove.
[0012] Preferably, the axial direction of the guide roller is perpendicular to the horizontal plane, and the interior of the long groove is connected to the inner wall of the side groove.
[0013] Preferably, the side groove extends laterally through the top of the loading platform, the worktable, and the unloading platform, and the side groove is located on both sides of the lower mold.
[0014] Preferably, the middle trough and the lower mold are arranged side by side along the plastic conveying direction, and the middle trough is located between the two side troughs.
[0015] Preferably, the side of the inclined guide plate facing the unloading platform is an inclined surface, and the height difference between the top of the inclined surface and the top of the middle belt conveyor is greater than the thickness of the plastic.
[0016] Preferably, the top of the inclined surface is close to the unloading platform, and the bottom of the inclined surface is far from the unloading platform.
[0017] Preferably, the waste collection assembly further includes a collection box disposed below the inclined guide plate, the collection box being located below the output end of the intermediate belt conveyor.
[0018] The beneficial effects of this utility model are:
[0019] This invention utilizes two side conveyors and guides horizontally positioned between the tops of the loading platform, processing platform, and unloading platform. This allows sheet-like plastic to be automatically fed sequentially into the cutting molds, and waste material is automatically transported to a collection box after stamping and cutting. This achieves automatic and self-collection of waste, preventing waste from accumulating around the cutting equipment and increasing the workload of subsequent cleaning. Furthermore, operators only need to use a suction cup-type pick-up rod to remove the cut plastic, greatly improving the operational safety of sheet-like plastic during the stamping and cutting process and preventing accidents caused by operational errors.

[0029] like Figures 1 to 4 As shown, a waste collection assembly for a plastic trimming machine includes a loading platform 2 and a unloading platform 1 respectively disposed opposite each other on both sides of the worktable. The waste collection assembly also includes:
[0030] Two side grooves 10 are connected side by side to the top of the unloading platform 1 and the loading platform 2. The side grooves 10 are equipped with side belt conveyors 3 for conveying plastic. On one side of the loading platform 2, a sheet of plastic (hereinafter referred to as plastic) is placed between the two side belt conveyors 3, so that the two opposite edges of the plastic are respectively placed on the top of the two side belt conveyors 3. The two side belt conveyors 3 work together to efficiently and accurately convey the plastic to the top of the lower mold located on the top of the worktable, so that the plastic can be stamped and cut into plastic of a fixed size and shape. After stamping and cutting, the plastic can be continuously conveyed to the lower loading platform 1 through the joint cooperation of the two side belt conveyors 3.
[0031] A central trough 11 is located at the top of the unloading platform 1. Inside the central trough 11 is a central belt conveyor 4 for assisting in the transport of waste materials. The central belt conveyor 4 and the side belt conveyor 3 have the same structure, including a drive wheel that rotates on the side of the central trough 11 away from the lower mold, and a driven wheel that rotates on the side of the central trough 11 closer to the lower mold. A conveyor belt is fitted between the drive wheel and the driven wheel. The difference between the central belt conveyor 4 and the side belt conveyor 3 is the conveying length and width of the conveyor belt. The former has a smaller conveying length, but a larger width. With this design, after the waste material is heated, softened, and stamped and cut, it can work together with the two side belt conveyors 3 to stably transport the softened waste material to the designated waste collection location.
[0032] A drive unit 5 is used to drive the central belt conveyor 4 and the two side belt conveyors 3 to operate synchronously. The drive unit 5 includes a horizontal shaft fixed between the driving wheels in the central belt conveyor 4 and the two side belt conveyors 3, a servo motor for driving the horizontal shaft to rotate, and a linkage shaft fixed between the driven wheels in the two side belt conveyors 3. With this design, the central belt conveyor 4 and the two side belt conveyors 3 can be driven to operate synchronously, so that the three can cooperate synchronously and stably transport plastic waste to the unloading table 1, the worktable and the loading table 2, so as to avoid the problem of plastic waste accumulating and stagnating on the unloading table 1, the worktable and the loading table 2, which would affect the efficiency of plastic stamping and cutting.
[0033] Two horizontal support arms 7 are arranged side by side outside the unloading platform 1, and an inclined guide plate 8 is fixed between the two horizontal support arms 7.
[0034] The guide 6 is arranged in parallel between the loading platform 2 and the unloading platform 1. The guide 6 is used to constrain the movement direction of the plastic during plastic loading and waste unloading, so that the plastic can be efficiently and accurately conveyed to the stamping and cutting position and the designated waste collection position. This can not only prevent the operator's body parts from being between the lower and upper molds, thus eliminating the problem of injury due to operational errors and improving the operator's operational safety, but also prevent waste from accumulating on the worktable and affecting subsequent stamping and cutting operations, or prevent waste from being randomly discarded in the processing workshop, increasing the workload of subsequent cleaning.
[0035] like Figures 2 to 4 As shown, the guide member 6 includes a guide strip 61 fixed between the top of the unloading platform 1 and the loading platform 2. A long groove 62 is provided through the two vertical surfaces of the guide strip 61, and guide rollers 63 are arranged in parallel and rotatably inside the long groove 62.
[0036] The axial direction of the guide roller 63 is perpendicular to the horizontal plane, and the interior of the long groove 62 is connected to the inner wall of the side groove 10. This design can limit and guide the plastic boundary when the two side belt conveyors 3 work together to transport plastic. It can also reduce the friction of the plastic during the conveying process through the rolling friction between the plastic and the guide roller 63, thereby improving the stability and smoothness of plastic conveying.
[0037] like Figures 1 to 4 As shown, the side groove 10 extends horizontally through the top of the loading platform 2, the worktable, and the unloading platform 1, and the side groove 10 is located on both sides of the lower mold.
[0038] The middle trough 11 and the lower die are arranged side by side along the plastic conveying direction. The middle trough 11 is located between the two side troughs 10. This design allows the plastic to be automatically conveyed from the top of the loading platform 2 to the top of the lower die on the worktable and the top of the unloading platform 1 in sequence. Finally, the waste material remaining after stamping and cutting is conveyed to the designated waste collection location to complete the centralized collection of waste material, so as to facilitate subsequent centralized processing, reduce the workload of subsequent waste cleaning and maintain the cleanliness of the stamping and cutting environment.
[0039] like Figures 1 to 3 As shown, the side of the inclined guide plate 8 facing the unloading platform 1 is an inclined surface, and the height difference between the top of the inclined surface and the top of the middle belt conveyor 4 is greater than the thickness of the plastic.
[0040] The top of the inclined surface is close to the unloading platform 1, and the bottom of the inclined surface is far away from the unloading platform 1. This design allows relatively hard plastic waste to impact the inclined surface of the inclined guide plate 8 under the conveying thrust of the side belt conveyor 3 and the middle belt conveyor 4, so that the impact side of the waste can be deflected downwards, making it easier to collect the waste.
[0041] like Figures 1 to 3 As shown, the waste collection assembly also includes a collection box 9 located below the inclined guide plate 8. The collection box 9 is located below the output end of the intermediate belt conveyor 4. This design allows relatively hard waste to fall accurately into the collection box 9 under the limiting and guiding effect of the inclined guide plate 8. Furthermore, for waste that has been heated and softened, it will fall into the interior of the collection box 9 between the inclined guide plate 8 and the output end of the intermediate belt conveyor 4, thus completing the centralized collection of waste and reducing the workload of subsequent cleaning.
[0042] Working principle: A sheet of plastic (hereinafter referred to as plastic) is placed between two side belt conveyors 3 on one side of the loading platform 2, with the two opposite edges of the plastic resting on the top of the two side belt conveyors 3 respectively. The two side belt conveyors 3 work together to efficiently and accurately transport the plastic to the top of the lower mold located on the top of the worktable, so that it can be stamped and cut into plastic of a fixed size and shape. For plastics with higher brittleness, they need to be heated to soften them before they can be stamped and cut. After stamping and cutting, the relatively hard or softened waste material is stably transported to the designated waste collection position by the middle belt conveyor 4 in cooperation with the two side belt conveyors 3. The relatively hard plastic will hit the inclined surface of the inclined guide plate 8, and under the limiting and guiding action of the inclined guide plate 8, the waste material will fall accurately into the inside of the collection box 9. The waste material that has been heated and softened will fall into the inside of the collection box 9 from between the inclined guide plate 8 and the output end of the middle belt conveyor 4, completing the centralized collection of waste material, so as to reduce the workload of subsequent cleaning.
