Description

Technical Field

[0001] This utility model relates to the technical field of light guide plate processing equipment, specifically to a waste collection device for cutting light guide plates. Background Technology

[0002] During the production of light guide plates, the cutting process generates a large amount of scrap and debris. Traditional waste collection methods mainly rely on open waste bins or simple storage devices, which have the following problems:

[0003] Low capacity: Waste is loosely piled up, taking up a lot of space and requiring frequent removal, which affects production efficiency.

[0004] Handling difficulties: Uncompressed waste is bulky and lightweight, making it easy to scatter during transportation and increasing labor costs.

[0005] Insufficient stability: Some equipment attempts to use a compression mechanism, but lacks guide and limit switches, and the extrusion plate is prone to tilting, resulting in uneven distribution of waste material or even jamming.

[0006] Inconvenient to clean: Once the waste is compacted, the integrated collection box is difficult to remove and requires manual digging, which is cumbersome and poses a safety hazard.

[0007] To address the aforementioned problems, there is an urgent need for a waste collection device that can compress waste, increase the single-use capacity, and is easy to disassemble and clean. Utility Model Content

[0008] This utility model provides a waste collection device for cutting light guide plates. Through the cooperation of a modular, detachable collection box and a guide rail limiting compression plate, it achieves efficient compression, stable storage, and convenient cleaning of waste, specifically solving the following problems:

[0009] Increase single-batch waste capacity: Compact loose waste into a cake shape using an extrusion plate, reducing volume by 30% to 50% and lowering handling frequency.

[0010] Enhanced compression stability: The extrusion plate is limited by guide rails to ensure vertical lifting and avoid skewing and jamming.

[0011] Optimize the waste removal process: The collection box can be quickly disassembled into two halves, allowing for direct separation and removal of the compressed waste cake without manual digging.

[0012] To achieve the above objectives, this utility model provides the following technical solution:

[0013] This utility model provides a waste collection device for cutting light guide plates, including a base. Two modular two-section square boxes are detachably installed on the top of the base. The two modular two-section square boxes are detachably spliced ​​together to form a square waste collection box. Guide rails are fixedly installed on the two opposite inner side walls of the square waste collection box. A pressing plate that can be raised and lowered and slid is horizontally arranged on the top of the square waste collection box. The two opposite outer side walls of the pressing plate are provided with slots designed to fit the guide rails. The pressing plate slides into the inner cavity of the square waste collection box.

[0014] Furthermore, the top of the base has two symmetrically distributed square cavities, and the bottom of the two modular bi-square boxes is fixedly installed with square blocks, which are respectively inserted into the corresponding square cavities.

[0015] Furthermore, a support frame is vertically fixedly installed on the top of the base, and an electric cylinder is vertically fixedly installed on the top of the support frame. The output end of the electric cylinder extends through to the bottom of the support frame, and a pressure sensor is installed between the output end of the electric cylinder and the extrusion plate.

[0016] Furthermore, L-shaped side columns are vertically fixedly installed on the top of both modular diagonal square boxes, and the top sidewalls of the two guide rails are respectively fixedly connected to the corresponding L-shaped side columns.

[0017] Furthermore, two opposite outer walls of the two modular diagonal square boxes are fixedly installed with split snap-fit ​​strips, and the two parallel split snap-fit ​​strips are combined to form a complete snap-fit ​​strip.

The two modular bi-square boxes are connected by inserts and slots to form a square waste collection box.

[0019] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0020] The extrusion plate compacts the waste into a dense cake shape, increasing the single-time capacity by more than 50% and significantly reducing the frequency of collection.

[0021] The electric cylinder drive, in conjunction with a pressure sensor, enables controllable compression, preventing waste material from rebounding or damaging the equipment.

[0022] The extrusion plate is limited by guide rails to ensure vertical lifting and avoid skewing or wear caused by uneven force.

[0023] The collection box can be quickly split in two, directly exposing the compressed waste cake, which can be removed without tools, greatly improving operational efficiency.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0037] The present invention will be further described below with reference to the embodiments.

[0038] Example 1

[0039] Reference Figure 1-5 This first embodiment of the present invention discloses a waste collection device for cutting light guide plates, including a base 1. The base 1 is welded from Q235 steel and the surface is treated with rust prevention. Two modular bi-square boxes 2 are detachably installed on the top of the base 1. The box body is made of 2mm thick 304 stainless steel plate. The two modular bi-square boxes 2 are detachably spliced ​​together to form a square waste collection box by M8 bolts.

[0040] The square waste collection box has guide rails 22 fixedly installed on its two opposite inner sidewalls. The guide rails 22 are made of 45# steel and have been hardened to a surface roughness of Ra1.6. A sliding, liftable extrusion plate 15 is horizontally positioned above the square waste collection box. The bottom of the extrusion plate 15 can be fitted with anti-slip textures to suppress rebound. The extrusion plate 15 is made of 15mm thick aluminum alloy plate and weighs approximately 8kg. The two opposite outer sidewalls of the extrusion plate 15 have slots designed to fit snugly against the guide rails 22. The slots are 21mm wide, 15mm deep, and have a clearance of 0.5mm. The extrusion plate 15 slides into the inner cavity of the square waste collection box, with a maximum stroke of 400mm.

[0041] Example 2

[0042] Reference Figure 1-5 This is the second embodiment of the present invention, which differs from the first embodiment in that: the top of the base 1 has two symmetrically distributed square cavities 11, each with dimensions of 100mm × 50mm × 20mm and a tolerance of ±0.1mm. Square blocks 26, each 95mm × 45mm × 15mm in size and injection molded from nylon material, are fixedly installed on the bottom of each of the two modular bi-square square boxes 2. The two square blocks 26 are respectively inserted into their corresponding square cavities 11 with a fitting gap of 0.5mm.

[0043] A support frame 12 is vertically fixed to the top of the base 1, and an electric cylinder 13 is vertically fixed to the top of the support frame 12. The electric cylinder 13 is a model SEA50-500 with a thrust of 5000N, a stroke of 500mm, and a speed of 50mm / s. The action of the electric cylinder 13 is controlled by a PLC or a manual button. The output end of the electric cylinder 13 extends through to the bottom of the support frame 12. A pressure sensor 14 is installed between the output end of the electric cylinder 13 and the extrusion plate 15. The sensor has a range of 0-10kN and an accuracy of ±1%FS. The pressure sensor 14 is electrically connected to the electric cylinder controller and automatically stops when overpressure occurs.

[0044] Both modular, bi-square boxes 2 have L-shaped side columns 21 vertically fixedly installed on their tops, with a height of 550mm. The top sidewalls of the two guide rails 22 are respectively fixedly connected to the corresponding L-shaped side columns 21 using M6 hex socket screws with a torque of 12N·m.

[0045] Two modular, two-part square boxes 2 are fixedly installed with separate snap-fit ​​strips 23 on their two opposite outer side walls. The snap-fit ​​strips are 40mm wide and 5mm thick. The two parallel separate snap-fit ​​strips 23 are combined to form a complete snap-fit ​​strip. The square waste collection box is provided with plug strips 24 on both sides. The plug strips 24 have a trapezoidal cross section. The two plug strips 24 are snapped onto the complete snap-fit ​​strip from top to bottom. The snap-fit ​​angle is 15° and the interference is 0.2mm.

[0046] Two modular, two-section square boxes 2 are vertically fixed with handles 25 on opposite sides. The handles 25 are made of φ25mm PVC pipe with a knurled surface. Each of the two modular, two-section square boxes 2 has a slot on its opposite side and a fixed insert strip. The two modular, two-section square boxes 2 are connected by insert strips and slots to form a square waste collection box with a 0.3mm gap between the insertion and fitting.

[0047] [Note: The above parameters are based on common industrial standards and can be adjusted according to specific working conditions in actual applications. Material selection takes into account strength, corrosion resistance, and cost factors, and tolerance requirements are specified for key mating dimensions. The drive component selection meets the compression requirements of light guide plate waste (density approximately 1.2 g / cm³), and pressure sensor 14 can prevent overload damage to the device.]

[0048] The remaining structure is the same as that in Example 1.

[0049] Detailed work process

[0050] Waste collection stage

[0051] Waste generated after the light guide plate is processed by the cutting machine, including scraps and debris, falls freely or is conveyed by a conveyor belt to a square waste collection box formed by splicing modular two-section square boxes 2. The waste initially accumulates loosely at the bottom of the collection box, and gradually increases as cutting continues.

[0052] Start the compression program

[0053] When the waste material accumulates to a certain height, the operator activates the electric cylinder 13. The output end of the electric cylinder 13 extends downward, pushing the extrusion plate 15 connected to it to descend vertically along the guide rail 22. The slots on both sides of the extrusion plate 15 fit tightly against the guide rail 22 to ensure that there is no deviation or shaking during the pressing process.

[0054] Waste compression and crushing

[0055] The extrusion plate 15 continuously presses down, applying uniform pressure to the waste material, gradually compressing the loose waste into a compact, disc-like structure. If the waste material contains large pieces of scrap, the continuous pressure of the extrusion plate 15 can break them, further reducing the volume. The pressure sensor 14 monitors the extrusion force in real time to prevent overload damage to the equipment or waste rebound.

[0056] Compression complete and reset

[0057] When the waste material is compressed to the set height or the pressure reaches the preset value, the electric cylinder 13 stops pressing down and automatically retracts, driving the extrusion plate 15 to rise to the initial position, ready for the next compression. The compressed waste cake occupies significantly less space, allowing the collection box to hold more waste material.

[0058] Waste removal and box disassembly

[0059] When the waste collection bin is nearly full, the operator grasps the handles 25 on the two modular bi-square bins 2 and pulls them upwards, causing the connector strip 24 to detach from the split locking strip 23. Since the bin is composed of two symmetrical modular bi-square bins 2, it can be directly separated into two halves after disassembly, exposing the compressed waste cake, which is convenient for overall removal or transfer to the recycling area.

[0060] Reassembly of the enclosure

[0061] After cleaning or replacing the waste, align the inserts of the two modular two-part square boxes 2 with the slots and reassemble them, so that the separate snap-fit ​​strips 23 are combined into a complete snap-fit ​​strip, and fixed by the insert strips 24. The square block 26 at the bottom of the box is inserted into the square cavity 11 of the base 1 to ensure stable positioning. After the device is reset, it can continue to be used for waste collection.

[0062] Key structural synergy

[0063] Guide rail 22 and extrusion plate 15: ensure stable compression process and avoid skewing.

[0064] Electric cylinder 13 and pressure sensor 14: provide controllable pressure to prevent overload.

[0065] Modular two-part square box 2: The split design makes it easier to remove waste materials.

[0066] Split-type snap-fit ​​strip 23 and plug-in strip 24: Enable quick disassembly and assembly.

[0067] This device significantly improves the collection efficiency of light guide plate waste through automated compression and modular design, reduces manual intervention, and is suitable for high-capacity processing environments.
