Description

Technical Field

[0001] This utility model belongs to the field of door and window manufacturing technology, and specifically relates to a waste collection component for door and window profiles. Background Technology

[0002] Door and window profiles refer to the raw materials used to make door and window frames. They are usually made of metal, plastic, wood, or composite materials. During door and window processing, the profiles need to be cut and drilled, which produces scraps, metal shavings, or plastic fragments. In common aluminum alloy processing, about 5%-10% cutting waste is generated.

[0003] Currently, Chinese utility model patent CN222844274U discloses a waste collection device, belonging to the field of PVC window and door cutting technology. Specifically, it is a waste collection device for PVC window and door cutting saws, including a workbench with two symmetrical through slots on its upper side, and a movable collection mechanism. By turning on the motor, the lead screw is driven to rotate, and the rotation of the lead screw drives the movable brush plate to move through the threaded engagement. Multiple bristles on the lower side of the movable brush plate can scrape the waste generated during cutting on the workbench surface, and finally, the waste falls into the collection box through multiple discharge slots for unified collection. By holding and pulling two L-shaped movable blocks, the two L-shaped movable blocks slide along the outside of two sliding rods. When the two L-shaped movable rods separate from the two insertion holes, the collection box can be disassembled for periodic deep cleaning. This solves the problem of timely collection and cleaning of waste after cutting PVC windows and doors.

[0004] In the aforementioned structure, the brush bristles on the underside of the moving brush plate scrape the waste material on the worktable surface. This means that during the production process, after each or several cuts, the machine needs to be stopped to wait for the moving brush plate to clean the worktable. As mentioned above, "about 5%-10% of cutting waste is generated in common aluminum alloy processing." This also means that waste material will accumulate on the worktable surface at a relatively fast speed. In some more complex door and window models, the machine needs to be stopped after each cut to wait for the moving brush plate to clean the worktable, which greatly reduces production efficiency.

[0005] Meanwhile, the moving brush plate often operates at a slow speed because of the fine waste dust generated during cutting. A faster operating speed would cause the waste dust to fly up, leading to workers inhaling it and causing personal injury such as pneumoconiosis, which further reduces work efficiency. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a waste collection component for door and window profiles.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a door and window profile waste collection component, including a cutting bed, the cutting bed including a frame, the inner wall of the frame having a plurality of supporting connecting rods linearly arrayed and fixed, the bottom of the cutting bed having a collection hopper having an opening at the bottom of the collection hopper, and a collection box being detachably connected to the opening at the bottom of the collection hopper via a snap-fit ​​component; the bottom of the collection hopper having a plurality of connecting columns fixed, and the bottom of the connecting columns having a vibration generator fixed.

[0008] Preferably, the top of each supporting link is provided with inclined surfaces on both sides, the angle formed by the inclined surfaces and the vertical direction is not less than 30 degrees, and the top of the supporting link is triangular through the inclined surfaces.

[0009] Preferably, the inner wall of the vibration generator is provided with a moving frame, the inner wall of the moving frame is provided with a vibrating element, the inner wall of the vibrating element is provided with a motor, and the output end of the motor is fixed with an eccentric wheel, the axis of the eccentric wheel does not coincide with the axis of the motor.

[0010] Preferably, the vibration generator has multiple moving circular grooves on both sides of its inner wall, and collision columns are slidably connected to the inner walls of the moving circular grooves. One end of each collision column is fixed to the side of the moving frame. Multiple limiting plates are fixed to the inner wall of the vibration generator. The inner walls of the limiting plates are slidably connected to the circumferential surfaces of the collision columns, and a return spring is provided on the circumferential surfaces of the collision columns.

[0011] Preferably, multiple dampers are fixed to the top of the vibrating element and the top of the vibrating element, and one end of the damper is fixed to the inner wall of the vibration generator.

[0012] Preferably, vertical grooves are provided on both sides of the inner wall of the moving frame, and wing plates are slidably connected to the inner wall of the vertical grooves. One end of the wing plate is fixed to the side of the vibrating element.

[0013] Preferably, trapezoidal grooves are provided at the top and bottom of the inner wall of the vibration generator, and a trapezoidal component is slidably connected to the inner wall of the trapezoidal groove, with one end of the trapezoidal component fixed to the surface of the moving frame.

[0014] Preferably, protective pads are glued to both sides of the trapezoidal component, and the surface of the protective pads is provided with reserved grooves.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. This utility model replaces the traditional cutting table with a cutting bed composed of a frame and supporting rods, so that most of the waste generated during the cutting process can fall directly into the collection hopper. The dust remaining on the supporting rods is gradually drawn into the collection hopper by the vibration of the vibration generator, and continues to fall into the collection box under the influence of vibration, which makes it convenient for workers to collect and replace. At the same time, there is no need to stop the machine, which greatly increases work efficiency and the convenience of operation for workers, while reducing the structure and reducing the failure rate.

[0017] 2. This utility model limits and reduces the vertical vibration generated by the vibrating component through the damper. At the same time, the collision column and the moving circular groove allow the horizontal vibration to be transmitted well through the collision between the rubber braking circular groove and the vibration generator. This causes the waste dust to gradually leave the support rod under the influence of horizontal vibration. Under the influence of small vertical vibration, the friction between the waste dust and the support rod is greatly reduced, and there is no obvious dust flying, which can better protect the workers.

[0018] 3. This utility model, through the sliding fit between the trapezoidal groove and the trapezoidal component, enables the moving frame to maintain a stable horizontal movement in the vibration generator, preventing abnormal wear. At the same time, the fit between the two can assist in the transmission of vertical vibration. The length of the trapezoidal groove is smaller than the width of the inner wall of the vibration generator, so that the return spring will not exceed its limit compression distance when compressed, thus improving its service life.

[0035] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0036] The specific embodiments of this utility model are described below with reference to the accompanying drawings:

[0037] Example 1:

[0038] refer to Figures 1-6 A waste collection assembly for door and window profiles includes a cutting bed 1, which includes a frame. Multiple supporting rods 2 are linearly arrayed and fixed to the inner wall of the frame. A collection hopper 201 is fixed to the bottom of the cutting bed 1. The bottom of the collection hopper 201 has an opening. A collection box 204 is detachably connected to the bottom opening of the collection hopper 201 through a snap-fit ​​assembly. Multiple connecting columns 202 are fixed to the bottom of the collection hopper 201. A vibration generator 203 is fixed to the bottom of the connecting columns 202.

[0039] Specifically, by replacing the traditional cutting table with a cutting bed 1 consisting of a frame and supporting rods 2, most of the waste generated during the cutting process can fall directly into the collection hopper 201. The dust remaining on the supporting rods 2 is gradually drawn into the collection hopper 201 by the vibration of the vibration generator 203, and continues to fall into the collection box 204 under the influence of vibration. This makes it easier for workers to collect and replace the waste without stopping the machine, greatly increasing work efficiency and ease of operation for workers, while also reducing the structural structure and failure rate.

[0040] Both sides of the top of the support link 2 are set as inclined planes 3, and the angle formed by the inclined planes 3 and the vertical direction is not less than 30 degrees. The top of the support link 2 is triangular through the inclined planes 3.

[0041] Specifically, the support rod 2 is set into a triangular shape by the inclined surface 3, so that the bottom of the support rod 2 has a smaller contact area with the door and window profiles and profile waste, and the waste is more likely to fall into the collection hopper 201.

[0042] The vibration generator 203 has a moving frame 4 on its inner wall, a vibrating element 401 on its inner wall, and a motor on its inner wall. The output end of the motor is fixed with an eccentric wheel 402. The axis of the eccentric wheel 402 does not coincide with the axis of the motor. Vibration is generated by the rotation of the eccentric wheel 402. The structure is simple and easy to maintain, which reduces production costs.

[0043] Multiple moving circular grooves 5 are provided on both sides of the inner wall of the vibration generator 203. A collision column 501 is slidably connected to the inner wall of the moving circular groove 5. One end of the collision column 501 is fixed to the side of the moving frame 4. Multiple limiting plates 502 are fixed to the inner wall of the vibration generator 203. The inner wall of the limiting plate 502 is slidably connected to the circumference of the collision column 501. A return spring 503 is provided on the circumference of the collision column 501. Multiple dampers 6 are fixed to the top of the vibrating element 401 and the top of the vibrating element 401. One end of the damper 6 is fixed to the inner wall of the vibration generator 203.

[0044] Specifically, the damper 6 limits and reduces the vertical vibration generated by the vibrating component 401. At the same time, the collision column 501 and the moving circular groove 5 allow the horizontal vibration to be transmitted well through the collision between the rubber brake circular groove 5 and the vibration generator 203. This causes the waste dust to gradually leave the support rod 2 under the influence of horizontal vibration. Under the influence of small vertical vibration, the friction between the waste dust and the support rod 2 is greatly reduced, and there is no obvious dust flying, which can better protect the workers.

[0045] Vertical grooves 7 are provided on both sides of the inner wall of the moving frame 4. A wing plate 701 is slidably connected to the inner wall of the vertical groove 7. One end of the wing plate 701 is fixed to the side of the vibrating element 401.

[0046] Specifically, the direct sliding between the vertical groove 7 and the wing plate 701 ensures that the vibrating element 401 maintains a stable vertical sliding position, preventing abnormal displacement of the vibrating element 401 during movement that could cause the damper 6 to bend and be damaged, thus improving the service life of the equipment.

[0047] Trapezoidal grooves 8 are provided on the top and bottom of the inner wall of the vibration generator 203. Trapezoidal component 801 is slidably connected to the inner wall of the trapezoidal groove 8. One end of the trapezoidal component 801 is fixed to the surface of the moving frame 4. Protective pads 9 are glued to both sides of the trapezoidal component 801. The surface of the protective pads 9 is provided with reserved grooves.

[0048] Specifically, the sliding fit between the trapezoidal groove 8 and the trapezoidal component 801 ensures that the moving frame 4 maintains a stable horizontal movement within the vibration generator 203, preventing abnormal wear. At the same time, the fit between the two assists in the transmission of vertical vibration. The smaller length of the trapezoidal groove 8 compared to the width of the inner wall of the vibration generator 203 ensures that the return spring 503 will not exceed its limit compression distance when compressed, thus significantly improving its service life.

[0049] Example 2:

[0050] Reference image Figures 1-6 The staff applied the structure disclosed in this utility model in the aluminum alloy profile processing workshop of a large door and window manufacturing enterprise;

[0051] The large amount of scrap and metal dust generated during the daily cutting process needs to be efficiently collected and treated. For this purpose, the door and window profile waste collection component described in this utility model is selected. The component includes a cutting bed 1, whose frame is made of Q235 carbon steel welded structure with dimensions of 3 meters long, 1.2 meters wide and 0.8 meters high. Multiple stainless steel support rods 2 are linearly arrayed and fixed on the inner wall of the frame. The top two sides of the support rods 2 are provided with inclined surfaces 3 at an angle of 35 degrees to form a triangular structure. A stainless steel collection hopper 201 is welded and fixed to the bottom of the cutting bed 1. The bottom of the collection hopper 201 has an opening and is detachably connected to a plastic collection box 204 with a capacity of 100 liters through a snap-fit ​​component. Four connecting columns 202 are welded and fixed to the four corners of the bottom of the collection hopper 201. A three-phase asynchronous vibration motor of model "YZO-10-2" is bolted to the bottom of the connecting columns 202 as a vibration generator 203. The rated power of the motor is 0.75kW, the speed is 2840rpm and the excitation force is 10kN.

[0052] The vibration generator 203 has a moving frame 4 inside, and a vibrating element 401 is installed inside the moving frame 4. The vibrating element 401 has a built-in motor that drives the eccentric wheel 402 to rotate and generate vibration. The vibrating element 401 is slidably connected to the moving frame 4 through the wing plate 701. The moving frame 4 is slidably engaged with the trapezoidal groove 8 on the inner wall of the vibration generator 203 through the trapezoidal part 801. The collision column 501 is slidably connected to the moving circular groove 5 and is provided with a return spring 503. The upper and lower ends of the vibrating element 401 are provided with dampers 6 to buffer the vibration. Protective pads 9 are glued to both sides of the trapezoidal part 801.

[0053] In actual production, the cutting equipment cuts aluminum alloy profiles, and the resulting scraps and dust fall into the collection hopper 201 through the gap between the support rods 2. Some of the dust attached to the support rods 2 is shaken off by the continuous vibration of the vibration generator 203 and slides into the collection box 204 along the collection hopper 201. The whole process does not require stopping the machine for cleaning, which significantly improves production efficiency and the cleanliness of the workshop environment.

[0054] The working principle of this utility model is as follows: During the cutting process of door and window profiles, the scraps and debris generated first fall naturally through the gaps between the support rods 2 on the cutting bed 1 and enter the collection hopper 201 below. Because the top of the support rod 2 is designed with a sloping surface 3, forming a triangular structure, the contact area between the waste and the support surface is effectively reduced, making the waste easier to slide off and avoiding accumulation;

[0055] Meanwhile, fine dust or deposits remaining on the surface of the support rod 2 are removed by the vibration generated by the vibration generator 203. The motor inside the vibration generator 203 drives the eccentric wheel 402 to rotate. Since the axis of the eccentric wheel 402 does not coincide with the axis of the motor, a periodic unbalanced force is generated, which drives the vibrating component 401 and the moving frame 4 to vibrate and promotes the waste to enter the collection box 204.

[0056] The vibrating element 401 is slidably connected to the moving frame 4 via the wing plate 701, ensuring stable vertical movement. Simultaneously, the moving frame 4 achieves stable horizontal sliding through the cooperation of the trapezoidal element 801 and the trapezoidal groove 8. The sliding cooperation between the collision column 501 and the moving circular groove 5 effectively transmits horizontal vibrations to the collection hopper 201, thereby shaking off the dust adhering to the support rod 2.

[0057] To prevent excessive vibration from damaging the equipment or causing dust to fly, dampers 6 are provided at both ends of the vibrating component 401 to absorb and buffer the vertical vibration energy. At the same time, a return spring 503 is provided on the collision column 501 to buffer and reset during vibration, ensuring smooth and continuous vibration transmission.

[0058] The shaken-off waste falls into the collection hopper 201 and enters the collection box 204 through its bottom opening. The collection box 204 is detachably connected to the collection hopper 201 by a snap-fit ​​component, which facilitates regular cleaning and replacement, and realizes centralized treatment of waste in continuous production.
