Description

Technical Field

[0001] This utility model relates to the field of soft towel production technology, specifically to a device for recycling soft towel edge material. Background Technology

[0002] Soft cotton wipes, a popular cleaning and care product, are primarily made of synthetic fibers such as polyester and viscose, processed using advanced spunlace nonwoven technology. These wipes are characterized by their softness, skin-friendliness, and lint-free properties, offering versatility for both wet and dry use, and are widely used in daily life.

[0003] In the production and processing of soft tissues, after the main manufacturing process is completed, the products are usually further processed using specialized equipment such as cutting machines. During this process, scraps and waste are inevitably generated, which are discharged through waste outlets on the equipment. To achieve centralized processing and subsequent recycling of waste, the industry commonly uses conveyor belts to transport the discharged waste. However, because the waste generated from soft tissue production is relatively lightweight, it is easily affected by external environmental factors (such as airflow and vibration) during transport, leading to instability in the transport process and even problems such as waste falling and accumulating, making it difficult to complete the transport operation efficiently and smoothly. Therefore, the existing waste transport methods in soft tissue production still have significant shortcomings and urgently need further improvement and refinement. Utility Model Content

[0012] Furthermore, a handle is installed on the cover plate, and a sealing gasket is fitted to the inner wall of the cover plate.

[0013] The beneficial effects of adopting the above-mentioned further solutions are:

[0014] The handle provides operators with a convenient point of force to open and close the cover, making it easy to pick up and put down the cover and the mesh box below; the sealing gasket can effectively enhance the sealing between the cover and the recycling box, reduce air pressure leakage in the recycling box, and ensure that the recycling box can form a stable negative pressure environment when the vacuum pump is working, thereby ensuring the adsorption and recycling effect of the soft towel edge material.

[0015] Furthermore, a mesh box is welded to the bottom end face of the cover plate, and the mesh box is slidably fitted inside the recycling bin.

[0016] The beneficial effects of adopting the above-mentioned further solutions are:

[0017] The mesh box can collect the scraps of the soft towels sucked into the recycling bin, preventing them from scattering randomly inside.

[0027] This utility model provides a device for recycling the edge material of soft handkerchiefs. It has the following beneficial effects:

[0028] By generating negative pressure through the operation of a vacuum pump, and using the conveying channel formed by the corrugated pipe and mounting frame, the scrap material generated during processing can be sucked from the waste discharge point of the equipment into the mesh box inside the recycling bin. This prevents the scrap material from scattering and causing a messy workshop environment. At the same time, the design of the mesh box makes the scrap material collection more centralized, and subsequent cleaning and reuse operations are more convenient. This improves the cleanliness of the production site and the resource utilization rate, and avoids the situation where the scrap material of cotton towels is scattered and affected by the conveyor belt after being discharged, which affects recycling.

[0038] Please see Figures 1 to 4 As shown, the embodiments provided by this utility model are as follows:

[0039] Example

[0040] The device for recycling soft towel scraps includes a recycling device housing 1, a vacuum pump 2, and a recycling bin 3.

[0041] A vacuum pump 2 is mounted on the rear end face of the inner wall of the recycling device housing 1 via a bracket. The vacuum pump 2 is connected to an extraction pipe 201 and a discharge pipe 202. A recycling box 3 is mounted on the bottom end face of the inner wall of the recycling device housing 1. A cover plate 4 is provided on the recycling box 3. A corrugated pipe 5 is mounted on the side end face of the recycling box 3. An installation bracket 501 is mounted on the end of the corrugated pipe 5 away from the recycling box 3.

[0042] The front end of the outer shell 1 of the recycling device is fitted with a cabinet door 101 via a hinge, and the bottom end of the outer shell 1 is fitted with a self-locking caster wheel 102. The cabinet door 101 allows operators to open the outer shell to inspect and maintain the internal components such as the vacuum pump 2 and the recycling box 3, as well as to remove the recycled scraps. The self-locking caster wheel 102 enables the entire recycling device to be moved, making it easy to adjust the placement of the device according to the location of the cotton towel processing equipment. The self-locking function also ensures that the device is firmly fixed during operation, preventing accidental movement from affecting the normal operation of the recycling work.

[0043] A handle is installed on the cover plate 4, and a sealing gasket is fitted to the inner wall of the cover plate 4. The handle provides a convenient force point for the operator to open and close the cover plate 4, making it easy to pick up and put down the cover plate 4 and the net box 401 below. The sealing gasket can effectively enhance the sealing between the cover plate 4 and the recycling box 3, reduce the air pressure leakage in the recycling box 3, and ensure that the recycling box 3 can form a stable negative pressure environment when the vacuum pump 2 is working, thereby ensuring the adsorption and recycling effect of the soft towel edge material.

[0044] A mesh box 401 is welded to the bottom surface of the cover plate 4. The mesh box 401 is slidably fitted inside the recycling bin 3. The mesh box 401 can collect the soft towel scraps sucked into the recycling bin 3 and prevent the scraps from scattering randomly inside the recycling bin 3. The design of the mesh box 401 sliding inside the recycling bin 3, together with the handle on the cover plate 4, allows the operator to remove the mesh box 401 from the recycling bin 3, which is convenient for subsequent processing of the recycled scraps, such as unified cleaning and reuse, thus improving the convenience of recycling operations.

[0045] The end of the extraction pipe 201 facing away from the vacuum pump 2 is installed in the recovery box 3. The recovery box 3 is connected to the vacuum pump 2 in gas through the extraction pipe 201. This connection method allows the vacuum pump 2 to extract air from the recovery box 3 through the extraction pipe 201 when it is working, forming a negative pressure in the recovery box 3. This ensures that the negative pressure can effectively act on the corrugated pipe 5, thereby smoothly sucking the soft towel edge material from the waste discharge point of the processing equipment into the recovery box 3.

[0046] The mounting bracket 501 is connected to the corrugated pipe 5. A silicone pad is attached to the mounting bracket 501. The connection between the mounting bracket 501 and the corrugated pipe 5 ensures that the edge material can smoothly enter the corrugated pipe 5 from the mounting bracket 501 and be transported to the recycling bin 3. The silicone pad has good sealing and flexibility. When the mounting bracket 501 is attached to the waste discharge point of the processing equipment, the silicone pad can enhance the sealing performance between the two, reduce negative pressure leakage, and at the same time prevent the mounting bracket 501 from being damaged by hard collision with the processing equipment, thus playing a role in protecting the equipment.

[0047] A hydraulic rod 502 is installed on the outer surface of the outer shell 1 of the recycling device. The output shaft of the hydraulic rod 502 is connected to the mounting frame 501. The hydraulic rod 502 can adjust the position of the mounting frame 501 so that the mounting frame 501 can fit against the waste discharge point of the processing equipment.

[0048] Working principle:

[0049] Equipment movement and fixation: The entire device is moved to the vicinity of the waste discharge point of the cotton towel processing equipment by means of the self-locking casters 102 on the bottom end of the outer shell 1 of the recycling device, and the device is fixed in place by means of the self-locking function to prevent displacement during operation.

[0050] Mounting bracket 501 position adjustment: Start the hydraulic rod 502 on the outer surface side of the recycling device housing 1. The output shaft of the hydraulic rod 502 pushes the mounting bracket 501 to move, so that the mounting bracket 501 fits against the waste discharge point of the processing equipment. The silicone pad on the mounting bracket 501 enhances the sealing between the two.

[0051] Negative pressure environment formation: Open the cabinet door 101 on the front side of the outer shell 1 of the recycling device, check that the internal components are correct, close the cabinet door 101, start the vacuum pump 2 which is installed on the rear side of the inner wall of the outer shell 1 of the recycling device through the bracket, the vacuum pump 2 draws air out of the recycling box 3 through the extraction pipe 201, so that the recycling box 3 forms a negative pressure, and the vacuum pump 2 can be connected to an external power supply and an external control switch for control and power supply.

[0052] Edge material suction and conveying: Under negative pressure, the edge material of the soft towel enters the mounting frame 501 connected to the corrugated pipe 5 from the waste discharge point of the processing equipment, and is then conveyed to the recycling box 3 through the corrugated pipe 5.

[0053] Edge material collection and processing: The edge material entering the recycling bin 3 is collected by the mesh box 401 welded to the bottom end of the cover plate 4. When the edge material needs to be processed, the operator can take the mesh box 401 out of the recycling bin 3 through the handle on the cover plate 4 for cleaning or reuse. The sealing gasket on the inner wall of the cover plate 4 ensures the sealing of the recycling bin 3 during operation.

[0054] Gas discharge: The air drawn by vacuum pump 2 is discharged through discharge pipe 202 to ensure the continuous and stable operation of the entire negative pressure system.
