Description

Technical Field

[0001] This invention relates to the field of waste recycling technology, and in particular to a waste recycling mechanism for trimmed plastic products. Background Technology

[0002] After injection molding, extrusion, or compression molding, plastic products (such as sheets, pipes, and shaped parts) often develop burrs or flash on their edges, which need to be removed through a trimming process to achieve a smooth, flat product appearance and meet required dimensional accuracy. Currently, in the trimming process of plastic products, operators typically use tools such as trimming knives, files, or electric trimming machines to cut the edges of the workpiece.

[0003] However, under existing trimming operation modes, especially in manual or semi-automatic trimming operations, the following drawbacks exist: the plastic shavings (cutting chips) generated during the trimming process lack effective directional guidance and collection methods, causing the shavings to easily fly around and accumulate on the trimming workbench. These flying shavings not only pollute the working environment and increase the cleaning burden of the workshop, but may also drift and adhere to the moving parts of the equipment, accelerating equipment wear.

[0004] To address the issue of countertop cleaning, the common practice is to manually vacuum the work surface using a handheld negative pressure vacuum cleaner (such as a vacuum cleaner) after the trimming work is completed. While this method effectively collects debris, it is an offline or reactive process. Operators must interrupt their regular trimming work to perform the cleaning task, resulting in a cumbersome procedure, extended downtime, and significantly impacting processing efficiency. Furthermore, debris that splashes onto the floor during trimming requires additional sweeping, further increasing labor costs.

[0005] To address the aforementioned issues, some existing trimming equipment attempts to prevent debris from flying by adding protective covers. However, these covers only provide shielding and cannot automatically collect accumulated debris, still requiring manual intervention for cleaning. Other technologies propose using air blowing or vacuum suction for cleaning, but their structural designs are often complex or primarily designed for metal cutting, lacking specificity and integration for the recycling of lightweight plastic debris. Summary of the Invention

[0006] This invention provides a waste recycling mechanism for plastic products after trimming, which can solve the following problems in the prior art: the plastic shavings (cutting chips) generated during the trimming process lack effective directional guidance and collection methods, causing the shavings to easily fly around and accumulate on the trimming workbench, and are difficult to clean.

[0007] A waste recycling mechanism for trimmed plastic products includes a workbench with a U-shaped support on the workbench and a trimming module on the U-shaped support. The trimming module is used to trim the plastic products. The workbench is also equipped with a support section for supporting the plastic products to be trimmed; The supporting part includes two sets of symmetrically arranged supporting plates. A first isolation cover is fixedly arranged on one side of the supporting plate, and a second isolation cover is fixedly arranged on the other side of the supporting plate. Both the first isolation cover and the second isolation cover are U-shaped structures. It also includes a flipping module, which drives the two side support plates to rotate to pour out and collect the cut plastic waste.

[0008] Preferably, the two sides of the bearing plate are respectively provided with positioning parts for positioning and fixing the plastic product to be trimmed; The positioning part includes positioning seats fixedly arranged on the two side bearing plates, and adjusting seats slidably arranged on the bearing plates. The positioning seats and adjusting seats on each set of bearing plates are arranged relatively parallel. The end of the adjusting seat away from the positioning seat is fixedly connected to the adjusting rod slidably inserted into the isolation cover. The adjusting rod is provided with a first spring.

[0009] Preferably, the trimming module includes a trimming motor, which is fixed on the adjustment plate, and the drive end of the trimming motor is fixedly provided with trimming ends. The U-shaped bracket is equipped with a movable module, which is used to drive the adjustment plate to perform multi-directional movement and adjustment.

[0010] Preferably, the mobile module includes a lateral drive mechanism arranged on a U-shaped bracket, a mobile frame is fixedly arranged on the drive end of the lateral drive mechanism, a lifting mechanism is provided on the mobile frame, and the drive end of the lifting mechanism is fixedly connected to the adjustment plate. The workbench is equipped with a longitudinal drive mechanism, and the two side bearing plates are respectively arranged on the drive end of the longitudinal drive mechanism.

[0011] Preferably, the flipping module includes an adjustment part and a rotating part. The adjustment part is used to drive the two side support plates to move closer to each other or further apart, and the rotating part is used to drive the two side support plates to rotate synchronously.

[0012] Preferably, the driving end of the longitudinal driving mechanism is fixedly provided with a guide plate, the guide plate is provided with a T-shaped slide groove, a T-shaped slide seat is symmetrically slidably arranged in the T-shaped slide groove, a support is fixedly arranged on the T-shaped slide seat, and the two side bearing plates are rotatably connected to the support through support shafts respectively.

[0013] Preferably, the adjustment unit includes linear guides symmetrically fixed on both sides of the worktable, an inclined guide is fixedly arranged at the end of the linear guide away from the worktable, the two inclined guides are inclined in a direction away from each other, a linear guide groove is opened in the linear guide, and an inclined guide groove connected to the linear guide groove is opened in the inclined guide. The support has a limiting plate fixedly arranged on one side, and the limiting frame has a pin fixedly arranged at the end away from the support, which is slidably embedded in the guide groove.

[0014] Preferably, the rotating part includes a gear fixed on the support shaft, and a stop is fixedly arranged on the support. A rod is slidably inserted into the stop, and the other end of the rod is fixedly connected to a rack. The rack meshes with the gear. A second spring is provided on the rod. The end of the rack away from the stop is fixedly connected to the support rod, and a guide wheel is rotatably arranged at the end of the support rod. The workbench is also symmetrically equipped with baffles on both sides for contacting the guide wheels.

[0015] Preferably, at least two sets of support plates for supporting the bearing plate are fixedly arranged on both sides of the workbench.

[0016] Preferably, a collection box is also fixedly installed on one side of the workbench for collecting plastic waste stored on the support plate.

[0017] This invention provides a waste recycling mechanism for trimmed plastic products, which has the following beneficial effects: 1) This invention independently fixes U-shaped isolation covers on both sides of the support plate. When the two sets of support plates come into contact, the first and second isolation covers on both sides form a complete rectangular isolation cover. This rectangular isolation cover can prevent splashing when the subsequent trimming module trims the plastic product, thus avoiding the plastic debris from flying everywhere. This achieves the effect of initial isolation of the cut plastic debris, which is convenient for subsequent recycling. After the plastic product is trimmed, the cut plastic waste is temporarily stored on both sides of the support plate. After the plastic product is unloaded, the two sides of the support plate can be flipped synchronously by the flipping module to achieve the effect of dumping. The plastic waste temporarily stored on the two sides of the support plate is poured out and collected uniformly. This invention does not require the use of negative pressure equipment to suck up the plastic waste on the support plate, which further ensures the recycling efficiency of plastic waste. 2) When recycling trimming debris on both sides of the bearing plate, the present invention can first drive the two bearing plates to move away from each other by a certain distance through the adjustment part, and then drive the two bearing plates to rotate towards each other by a certain angle through the rotation part, so that the trimming debris on the bearing plate can be automatically discharged under the action of gravity, thereby achieving the collection effect. The adjustment part set in this embodiment can effectively avoid the interference phenomenon of the two bearing plates during the rotation process, and the stability is higher. 3) When the longitudinal drive mechanism of the present invention drives the pin to the position of the inclined guide groove, the guide wheel moves to the state of contact with the baffle. As the two bearing plates move away from each other, the relative movement between the rack and the baffle is generated by the cooperation of the baffle and the guide wheel. During this process, the rack can drive the gear to rotate, thereby achieving the effect of driving the bearing plate to rotate, so as to dump the waste on the bearing plate. The adjustment part and the rotation part of the present invention can automatically adjust the two bearing plates to move away from each other and rotate as the longitudinal drive mechanism drives the bearing plate to move longitudinally. There is no need to set up other servo drive equipment to adjust the movement of the bearing plate, which not only reduces the cost, but also ensures synchronization and stability.

Detailed Implementation

[0020] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0021] Example 1

[0022] like Figures 1 to 5 As shown, the present invention provides a waste recycling mechanism for trimming plastic products, including a workbench 1, a U-shaped support 101 on the workbench 1, and a trimming module on the U-shaped support 101, which is used to trim the plastic products 6. In this embodiment, the workbench 1 is also provided with a support part for supporting the plastic product 6 to be trimmed; it should be noted that in this embodiment, when trimming the plastic product 6, the plastic product 6 can be placed on the support part for positioning, so that the stability of the plastic product 6 can be effectively guaranteed in the subsequent trimming process.

[0023] Specifically, the support unit includes two sets of symmetrically arranged support plates 401. A first isolation cover 4 is fixedly arranged on one side of the support plate 401, and a second isolation cover 5 is fixedly arranged on the other side of the support plate 401. Both the first isolation cover 4 and the second isolation cover 5 are U-shaped structures. It can be explained that in this embodiment, by independently fixing U-shaped isolation covers on the two side support plates 401, when the two sets of support plates 401 come into contact, the first isolation cover 4 and the second isolation cover 5 on both sides form a complete rectangular isolation cover. This allows the subsequent trimming module to perform trimming processing on the plastic product 6, so as to prevent splashing of the subsequently cut plastic debris. This achieves the effect of preliminary isolation of the cut plastic debris, which is convenient for subsequent recycling.

[0024] It also includes a flipping module, which drives the two side support plates 401 to rotate, so as to pour out and collect the cut plastic waste. It can be explained that after the plastic product 6 is trimmed in this embodiment, the cut plastic waste will be temporarily stored on the two side support plates 401. After the plastic product 6 is unloaded, the two side support plates 401 can be flipped synchronously by the flipping module to achieve the effect of dumping, so as to pour out the plastic waste temporarily stored on the two side support plates 401 and collect it uniformly. This embodiment does not require the staff to use additional negative pressure equipment to suck up the plastic waste on the support plates 401, which further ensures the recycling efficiency of plastic waste.

[0025] Example 2

[0026] Based on Example 1, please refer to Figures 2-6 Positioning parts are provided on both sides of the bearing plate 401 for positioning and fixing the plastic product 6 to be trimmed. It can be noted that in this embodiment, after the plastic product 6 is placed on the two sides of the bearing plate 401, the positioning parts provided on the two sides of the bearing plate 401 can be used to position and fix the plastic product 6 to ensure the stability of the plastic product 6 in the subsequent trimming process, thereby improving the processing quality of the plastic product 6.

[0027] For details, please refer to Figures 7-8 The positioning unit in this embodiment includes positioning seats 506 fixedly arranged on the two side support plates 401, and adjusting seats 505 slidably arranged on the support plates 401. The positioning seats 506 and adjusting seats 505 on each set of support plates 401 are arranged opposite to each other and parallel to each other. The end of the adjusting seat 505 away from the positioning seat 506 is fixedly connected to the adjusting rod 503 slidably inserted into the isolation cover. The adjusting rod 503 is provided with a first spring 504. One end of the first spring 504 is fixedly connected to the isolation cover, and the other end is fixedly connected to the end of the adjusting rod 503. It can be noted that when feeding the plastic product 6 to be trimmed, this embodiment... The adjusting rod 503 can be pulled to move the adjusting seat 505 away from the positioning seat 506, so that the plastic product 6 to be trimmed can be placed between the adjusting seat 505 and the positioning seat 506. After placement, the adjusting rod 503 is released, so that the first spring 504 pushes the adjusting seat 505 towards the positioning seat 506 under the action of elasticity, so as to clamp and fix the plastic product 6 between the adjusting seat 505 and the positioning seat 506, thereby achieving the effect of fixing the plastic product 6. Correspondingly, after the trimming is completed, the adjusting rod 503 is pulled again to drive the adjusting seat 505 to separate from the plastic product 6, and the trimmed plastic product 6 can be unloaded. As one embodiment of this invention, the trimming module includes a trimming motor 3, which is fixed on the adjustment plate 203. The driving end of the trimming motor 3 is fixedly provided with a trimming end head 301. The U-shaped bracket 101 is provided with a moving module, which is used to drive the adjustment plate 203 to perform multi-directional movement adjustment. It can be noted that in this embodiment, the plastic product 6 is placed on the two side bearing plates 401, and the position of the trimming end head 301 can be adjusted by the moving module to trim the edge of the plastic product 6.

[0028] It should be noted that you can refer to Figure 8 In this embodiment, the height of the adjustment seat 505 is less than the thickness of the plastic product 6, so that interference with the trimming end 301 is avoided during the subsequent trimming process. Accordingly, when it is necessary to trim the bottom edge of the plastic product 6, the plastic product 6 can be rotated 180 degrees after the upper edge trimming is completed, so that the bottom edge of the plastic product 6 can be trimmed through the trimming end 301.

[0029] Specifically, in this embodiment, the moving module includes a lateral drive mechanism 2 arranged on a U-shaped bracket 101. A moving frame 201 is fixedly arranged on the drive end of the lateral drive mechanism 2. A lifting mechanism 202 is provided on the moving frame 201. The drive end of the lifting mechanism 202 is fixedly connected to the adjustment plate 203. It can be noted that in this embodiment, when adjusting the lateral position and height of the trimming end 301, the adjustment can be made by the lateral drive mechanism 2 and the lifting mechanism 202 working together.

[0030] To ensure that the positioned plastic product 6 corresponds longitudinally to the position of the trimmed end 301, in this embodiment, please refer to... Figures 4-6 The workbench 1 is equipped with a longitudinal drive mechanism 204, and the two side bearing plates 401 are respectively arranged on the drive end of the longitudinal drive mechanism 204. It can be explained that during the trimming process of the trimming end 301 of this embodiment on the plastic product 6, the longitudinal drive mechanism 204 can cooperate with the transverse drive mechanism 2 and the lifting mechanism 202 to adjust the position of the two side bearing plates 401 so that the position of the fixed plastic product 6 corresponds to the position of the trimming end 301, thereby ensuring the trimming quality of the plastic product 6.

[0031] It should be further noted that the transverse drive mechanism 2, the lifting mechanism 202 and the longitudinal drive mechanism 204 in this embodiment can all adopt a screw and nut transmission structure or a synchronous belt transmission structure. This embodiment does not limit this, as long as it meets the actual application requirements.

[0032] In this embodiment, when the flipping module drives the two side support plates 401 to flip, since isolation covers are fixedly arranged on both side support plates 401 and the isolation covers have a certain height, in order to avoid interference between the first isolation cover 4 and the second isolation cover 5 during the flipping process, please refer to... Figures 3-7 The flipping module includes an adjustment section and a rotation section. The adjustment section is used to drive the two side support plates 401 to move closer together or further apart, and the rotation section is used to drive the two side support plates 401 to rotate synchronously. It can be noted that, in this embodiment, when recycling trimming debris on the two side support plates 401, the adjustment section can first drive the two side support plates 401 to move further apart by a certain distance, and then the rotation section can drive the two side support plates 401 to rotate towards each other by a certain angle, so that the trimming debris on the support plates 401 can be automatically discharged under the action of gravity, thereby achieving the collection effect. The adjustment section provided in this embodiment can effectively avoid interference between the two side support plates 401 during rotation, resulting in higher stability.

[0033] In this embodiment, to ensure the stability of the two bearing plates 401 as they move closer together or further apart, a guide plate 205 is fixedly arranged at the driving end of the longitudinal drive mechanism 204. A T-shaped groove 206 is provided on the guide plate 205, and a T-shaped slide block 207 is symmetrically arranged in the T-shaped groove 206. A support 7 is fixedly arranged on the T-shaped slide block 207. The two bearing plates 401 are rotatably connected to the support 7 through the support shaft 502. It can be noted that when the pushing part of this embodiment adjusts the two bearing plates 401 to move closer together or further apart, the two bearing plates 401 can drive the two T-shaped slide blocks 207 to move closer together or further apart in the T-shaped groove 206 through the support shaft 502, so as to ensure the stability of the movement of the two bearing plates 401. Meanwhile, when the longitudinal drive mechanism 204 in this embodiment drives the two side bearing plates 401 to move longitudinally, it does not interfere with the movement process of the push part adjusting the two side bearing plates 401 to move closer or further apart.

[0034] In one embodiment of this invention, the adjustment unit includes linear guides 701 symmetrically fixed on both sides of the workbench 1. An inclined guide 702 is fixedly arranged at the end of the linear guide 701 away from the workbench 1. The inclined guides 702 on both sides are inclined in a direction away from each other. A linear guide groove 707 is formed in the linear guide 701, and an inclined guide groove 708 connected to the linear guide groove 707 is formed in the inclined guide 702. A limiting plate 709 is fixedly arranged on one side of the support 7, and a pin 705 slidably embedded in the guide groove is fixedly arranged at the end of the limiting plate 709 away from the support 7. It can be noted that, as the plastic product 6 is trimmed, to facilitate loading and unloading, a... The longitudinal drive mechanism 204 drives the two side support plates 401 to move a certain distance away from the worktable 1. During this process, the support 7 can drive the pin 705 to slide along the straight guide groove 707. The two side support plates 401 are still in a close contact state. After the plastic product 6 is unloaded, the longitudinal drive mechanism 204 drives the guide plate 205 to continue to move away from the worktable 1. During this process, based on the setting of the inclined guide groove 708, the pin 705 can be guided and limited, so that the pin 705 can drive the two side support plates 401 to move away from each other by a certain distance, so as to avoid the interference between the first isolation cover 4 and the second isolation cover 5 during the subsequent flipping process.

[0035] Specifically, the rotating part includes a gear 501 fixed on the support shaft 502. A stop 710 is also fixedly arranged on the support 7. A rod 711 is slidably inserted into the stop 710. The other end of the rod 711 is fixedly connected to a rack 704. The rack 704 meshes with the gear 501. A second spring 703 is provided on the rod 711. One end of the second spring 703 is fixedly connected to the stop 710, and the other end is fixedly connected to the rack 704. The end of the rack 704 away from the stop 710 is fixedly connected to a support rod 706. A guide wheel 712 is rotatably arranged at the end of the support rod 706. The two sides of the worktable 1 are also arranged in a symmetrical manner. Each of the above is fixedly provided with baffles 103 for abutting against the guide wheel 712. It can be explained that when the longitudinal drive mechanism 204 of this embodiment drives the pin 705 to move to the position of the inclined guide groove 708, the guide wheel 712 just moves to the state of abutting against the baffle 103. As the two side bearing plates 401 move away from each other, the relative movement between the rack 704 and the baffle 710 can be generated by the cooperation of the baffle 103 and the guide wheel 712. During this process, the rack 704 can drive the gear 501 to rotate, thereby achieving the effect of driving the bearing plate 401 to rotate, so as to pour out the waste on the bearing plate 401. Based on this, the adjustment unit and the rotation unit of this embodiment can automatically adjust the two side bearing plates 401 to move away from each other and rotate when the bearing plate 401 is driven to translate longitudinally by the longitudinal drive mechanism 204. There is no need to set up other servo drive devices to adjust the movement of the bearing plate 401, which not only reduces the cost, but also ensures synchronization and stability.

[0036] Please refer to Figures 4-5 During the trimming process of the plastic product 6 on the support plate 401, in order to prevent the support plate 401 from rotating, in this embodiment, at least two sets of support plates 104 for supporting the support plate 401 are fixedly arranged on both sides of the workbench 1. Specifically, when the support plate 401 moves to the top of the workbench 1, the support plate 104 can support the support plate 401 to prevent the support plate 401 from rotating or shaking during the subsequent trimming process. Correspondingly, when the pin 705 moves to the position of the inclined guide groove 708, the support plate 104 loses its supporting function on the support plate 401, so that the support plate 401 can be driven to rotate in the future, avoiding interference.

[0037] Furthermore, in this embodiment, a collection box 102 is fixedly arranged on one side of the workbench 1 to collect the plastic waste stored on the support plate 401. Specifically, when the support plates 401 on both sides rotate and pour out the waste, the waste can be directly discharged into the collection box 102 to achieve the effect of automatic waste recycling.

[0038] A recycling method for waste materials after trimming of plastic products includes the following steps: Please refer to Figures 1-5 S1. Position the plastic product 6 on the support. S2. Trim the plastic product 6 using the trimming module; S3. After the plastic product 6 is trimmed, the cut plastic waste will be temporarily stored on the two side bearing plates 401. S4. After the plastic product 6 is unloaded, the two side support plates 401 are rotated synchronously by the flipping module to pour out the plastic waste temporarily stored on the two side support plates 401 and collect it in a unified manner.

[0039] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
