Description

Technical Field

[0001] This utility model relates to the technical field of fabric waste collection, specifically a waste edge collection mechanism for a fabric cutting machine. Background Technology

[0002] A fabric cutting machine is a mechanical device used for cutting fabric. It typically consists of a cutting tool and an adjustable worktable. The operator places the fabric on the worktable and then controls the movement of the cutting tool to complete the cutting work. Using a fabric cutting machine can improve cutting speed and accuracy, saving labor costs and time. It is widely used in the textile and garment industries, and is particularly suitable for fabric cutting in mass production. During the cutting process, the fabric cutting machine generates a large amount of scrap material, which needs to be collected and processed promptly.

[0003] Chinese patent with publication number CN221607278U discloses an automatic scrap recycling mechanism for a fabric cutting machine, which includes a recycling component and a conveying component. The recycling component includes a support platform, two connecting columns, a mounting column, a connecting shaft, a take-up roller, a positioning rod, a threaded groove, and a connecting cylinder. Connecting columns are provided on both sides of the top of the support platform, and a mounting column is provided at the top of one of the connecting columns.

[0004] In the above solution, the support column is removed by bolts, and the threaded limit plate is unscrewed. The connecting cylinder can be removed from the surface of the take-up roller, and a new connecting cylinder can be replaced to continue the scrap recycling operation. This results in the following disadvantages: when collecting scrap edges, there is no mechanism to adjust the tension of the scrap edges, which makes it easy for the scrap edges to overlap during collection, and the take-up roller cannot collect them evenly. Utility Model Content

[0005] The purpose of this utility model is to provide a waste edge collection mechanism for a fabric cutting machine, so as to solve the problem that when collecting waste edges, there is no mechanism to adjust the tension of the waste edges, which makes the waste edges easy to overlap during collection and prevents the winding roller from collecting them evenly.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a waste edge collection mechanism for a fabric cutting machine, comprising an installation frame, the installation frame being fixed to the inner wall of a workbench, an electric slide rail being fixed to the inner wall of the installation frame, a housing being fixed to the slider of the electric slide rail, the internal cavity of the housing being connected to the output end of an external air supply device via a connecting pipe, a connecting column being inserted into the inner wall of the housing, a sealing ring being fixed to the outer wall of the connecting column, the outer wall of the sealing ring being in contact with the inner wall of the housing, a limit frame being fixed to the bottom end of the connecting column, a limit roller being rotatably provided on the inner wall of the limit frame, a pressure relief valve being fixed to the right side of the housing, the input end of the pressure relief valve being connected to the internal cavity of the housing, and a take-up roller being rotatably provided on the inner wall of the workbench via a drive motor.

[0007] Preferably, a fabric cutting mechanism is slidably connected to the top surface of the workbench, and an installation groove is provided on the top surface of the workbench, with a conveyor belt installed on the inner wall of the installation groove.

[0008] Preferably, the outer wall of the take-up roller is fixed with two limiting strips, the outer wall of the take-up roller is fitted with a take-up cylinder, the inner wall of the take-up cylinder is provided with a limiting groove, and the limiting strips are slidably connected in the limiting groove.

[0009] Preferably, a guide plate is fixed to the inner wall of the workbench, and a placement groove is provided on the inner bottom surface of the workbench. A collection box is placed on the inner wall of the placement groove, and the collection box corresponds to the guide plate.

[0010] Preferably, a vibration motor is fixed to the bottom surface of the guide plate.

[0011] Preferably, the bottom surface of the mounting groove is provided with a fixing groove, and a cleaning brush is fixed on the inner wall of the fixing groove. The cleaning brush is in contact with the conveyor belt, and the guide plate corresponds to the cleaning brush.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. Through the coordinated action of the electric slide rail, housing, connecting column, sealing ring, limit frame, and pressure relief valve, the tension of the waste edge can be flexibly adjusted, automatically compensating for tension fluctuations. This ensures that the waste edge is tightly arranged in layers on the winding roller and winding drum under the lateral movement force of the electric slide rail, avoiding local accumulation or gaps, thus significantly improving the stability and effectiveness of the waste edge collection mechanism. The sliding cooperation between the limit strip and the limit groove allows for quick assembly and disassembly of the winding drum from the winding roller, enabling operators to easily replace winding drums with waste edges, saving labor and time costs associated with manually stripping the waste rolls during downtime.

[0014] Second, the inclined design of the guide plate guides fabric scraps and dust generated during the cutting process to slide directionally into the collection box, maintaining the cleanliness of the workbench area. It also clearly defines the roles of the guide plate and the take-up roller: the take-up roller handles strip-shaped waste edges, while the collection box handles small pieces, improving waste sorting efficiency. A vibration motor drives the guide plate to vibrate at high frequency, preventing lightweight fabric scraps (such as knitted fabric edges) from sticking to the guide plate surface due to static electricity or fiber adhesion. This forces the scraps to quickly pass through the guide plate into the collection box, avoiding manual intervention. A cleaning brush contacts the conveyor belt, scraping away fabric scraps, fibers, or dust adhering to the conveyor belt surface, preventing waste accumulation from affecting the conveyor belt's operating accuracy and ensuring that waste edges are completely separated from the conveyor belt before entering the collection process.

[0020] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1-4As shown, a waste edge collection mechanism for a fabric cutting machine includes a mounting frame 1, which is fixed to the inner wall of a workbench 2. An electric slide rail 3 is fixed to the inner wall of the mounting frame 1, and a housing 4 is fixed to the slider of the electric slide rail 3. The internal cavity of the housing 4 is connected to the output end of an external air supply device through a connecting pipe. A connecting column 5 is inserted into the inner wall of the housing 4, and a sealing ring 6 is fixed to the outer wall of the connecting column 5. The outer wall of the sealing ring 6 is in contact with the inner wall of the housing 4. A limit frame 7 is fixed to the bottom end of the connecting column 5, and a limit roller 8 is rotatably provided on the inner wall of the limit frame 7. A pressure relief valve 9 is fixed to the right side of the housing 4, and the input end of the pressure relief valve 9 is connected to the internal cavity of the housing 4. A take-up roller 10 is rotatably provided on the inner wall of the workbench 2 through a drive motor. A fabric cutting mechanism 11 is slidably connected to the top surface of the workbench 2. An installation groove 12 is opened on the top surface of the workbench 2, and a conveyor belt 13 is provided on the inner wall of the installation groove 12.

[0022] In use, when it is necessary to collect the waste edge, the first cut waste edge can be passed through the limiting frame 7 and wound around the outer wall of the take-up drum 15 on the take-up roller 10. Then, the electric slide rail 3, the external air supply device and the take-up roller 10 can be started in sequence. The external air supply device injects air into the cavity inside the housing 4 through the connecting pipe to form an air pressure chamber, which causes the connecting column 5 to drive the sealing ring 6 to slide on the inner wall of the housing 4. The change in air pressure can push the connecting column 5 to float up and down, thereby adjusting the tension of the waste edge.

[0023] If the internal pressure of the housing 4 is too high, the air pressure can be adjusted by the pressure relief valve 9 to adjust the connecting column 5 and the limiting frame 7 to a suitable position, automatically compensating for the tension fluctuation of the waste material edge (such as when the elasticity of the fabric is uneven or the speed changes). The waste material edge will be in close contact with the outer wall of the limiting roller 8. At this time, the electric slide rail 3 will drive the housing 4, the limiting frame 7 and the waste material edge to move axially. Thus, under the continuous force of the take-up roller 10, the waste material edge will be arranged in layers and tightly wound on the outer wall of the take-up drum 15, thereby collecting the waste material edge in a concentrated manner.

[0024] At the same time, the debris generated during the fabric cutting on the conveyor belt 13 will be guided to the collection box 19 for centralized collection under the action of the guide plate 17, so as to cooperate with the winding roller 10 to collect the waste in a modular manner.

[0025] Through the coordinated action of the electric slide rail 3, housing 4, connecting column 5, sealing ring 6, limit frame 7 and pressure relief valve 9, the tension of the waste material edge can be flexibly adjusted, and the tension fluctuation of the waste material edge can be automatically compensated. Thus, under the lateral movement force of the electric slide rail 3, the waste material edge is ensured to be arranged tightly in layers on the winding roller 10 and winding drum 15, avoiding local accumulation or gaps, thereby significantly improving the stability and performance of the waste material edge collection mechanism.

[0026] like Figure 1 , Figure 2 and Figure 4 As shown, two limiting strips 14 are fixed on the outer wall of the take-up roller 10. A take-up drum 15 is sleeved on the outer wall of the take-up roller 10. A limiting groove 16 is opened on the inner wall of the take-up drum 15. The limiting strips 14 are slidably connected in the limiting groove 16. A guide plate 17 is fixed on the inner wall of the worktable 2. A placement groove 18 is opened on the inner bottom surface of the worktable 2. A collection box 19 is placed on the inner wall of the placement groove 18. The collection box 19 corresponds to the guide plate 17.

[0027] During use, the sliding engagement of the limiting strip 14 and the limiting groove 16 allows the take-up drum 15 to be quickly detached from the take-up roller 10, enabling operators to easily replace the take-up drum 15 with waste material edges, thus saving labor and time costs associated with manually peeling off waste rolls during machine downtime. The inclined design of the guide plate 17 guides the fabric scraps and dust generated during the cutting process to slide directionally into the collection box 19, maintaining the cleanliness of the work area on the workbench 2. Simultaneously, the division of labor between the take-up roller 10 and the collection box 19 is clear: the take-up roller 10 handles strip-shaped waste material edges, while the collection box 19 handles small pieces, improving waste sorting efficiency.

[0028] like Figure 2 As shown, a vibration motor 20 is fixed on the bottom surface of the guide plate 17, and a fixing groove 21 is opened on the inner bottom surface of the mounting groove 12. A cleaning brush 22 is fixed on the inner wall of the fixing groove 21. The cleaning brush 22 is in contact with the conveyor belt 13, and the guide plate 17 corresponds to the cleaning brush 22.

[0029] During operation, the vibration motor 20 drives the guide plate 17 to vibrate at high frequency, preventing lightweight fabric scraps (such as the edges of knitted fabrics) from sticking to the surface of the guide plate 17 due to static electricity or fiber adhesion. This forces the scraps to quickly pass through the guide plate 17 into the collection box 19, avoiding manual intervention. The cleaning brush 22 contacts the conveyor belt 13 to scrape off fabric scraps, fibers, or dust adhering to the surface of the conveyor belt 13, preventing waste accumulation from affecting the running accuracy of the conveyor belt 13 and ensuring that the waste edges are completely separated from the conveyor belt 13 before entering the collection process.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
