Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric processing technology, and in particular to an automatic waste suction device for nonwoven fabric processing. Background Technology

[0002] Nonwoven fabric, as a widely used material, is widely used in many fields such as medical and health care, packaging, clothing, and construction due to its advantages such as light weight, high strength, and low cost. In the processing and production of nonwoven fabric, a large amount of waste and fiber dust are generated due to processes such as cutting, punching, and slitting. If these wastes are not cleaned up in time, they will not only affect the normal operation of the production line, but may also affect the product quality and pose certain safety hazards.

[0003] Traditional methods for cleaning up waste from nonwoven fabric processing mainly rely on manual sweeping or the use of semi-automatic vacuum equipment. This is not only labor-intensive but also inefficient, making it difficult to achieve centralized, comprehensive cleaning of the cutting area, resulting in poor dust collection. Furthermore, the cleaning process requires pausing the operation of processing equipment, making continuous and automated operations impossible and affecting the overall production rhythm.

[0004] Therefore, there is an urgent need for an automatic waste suction device for nonwoven fabric processing that can achieve centralized and efficient adsorption and cleaning of edge waste and fiber dust while processing operations are being carried out. Utility Model Content

[0005] In order to overcome the shortcomings of traditional nonwoven fabric processing, which relies on manual cleaning or semi-automatic dust collection equipment, resulting in low cleaning efficiency, incomplete dust collection, and the need to interrupt processing to affect continuous operation, this utility model provides an automatic waste suction device for nonwoven fabric processing that can achieve centralized and efficient adsorption and cleaning of edge waste and fiber dust while processing is being carried out.

[0006] To address the aforementioned problems, this utility model adopts the following technical solution: an automatic waste suction device for non-woven fabric processing, comprising a worktable, on which symmetrically distributed fixed plates are slidably arranged; a first elastic element connects the fixed plates to the worktable; a fixed seat is fixedly connected to the middle position of the worktable; a cylinder is mounted on the top of the fixed seat; a cutting assembly is mounted on the movable rod of the cylinder; the cutting assembly is equipped with two cutting heads, left and right; a first sliding rod is slidably arranged on the cutting head portion of the cutting assembly; and the first sliding rod is jointly provided with a protective... The protective cover has a dust suction port inside. A second elastic element is sleeved on the first sliding rod. The two ends of the second elastic element are respectively connected to the cutting component and the protective cover. The protective cover is connected to a dust suction pipe. A collection box is set on the table surface of the workbench. An air pump is installed on the collection box. The input end of the air pump is connected to the protective cover through the dust suction pipe, and the output end is connected to the internal space of the collection box, forming a complete negative pressure dust suction path. The collection box has a material discharge box inside. An exhaust port is opened on the top of the collection box, and a filter screen is set on the top of the exhaust port.

[0007] As a further preferred embodiment, the workbench surface has symmetrically distributed slots.

[0008] As a further preferred embodiment, the top of the material feeding box is fixedly connected to symmetrically distributed mounting seats, and a second slide rod is slidably arranged on the mounting seats. A locking block is fixedly connected to the bottom end of the second slide rod, and a third elastic element is sleeved on the second slide rod. The two ends of the third elastic element are respectively fixedly connected to the mounting seats and the locking block. The top of the filter screen is fixedly connected to symmetrically distributed mounting blocks, and a groove is opened on the mounting block. The mounting block and the locking block are engaged through the groove.

[0009] As a further preferred embodiment, the card block has a beveled structure on both sides.

[0010] As a further preferred embodiment, the top of the collection box is provided with symmetrically distributed electric guide rails, and sliding seats are slidably arranged on the electric guide rails, with cleaning brushes being arranged on the sliding seats together.

[0011] As a further preferred embodiment, the cleaning brush is located below the filter screen, with its brush head in contact with the bottom surface of the filter screen.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. The device integrates the cutting components with the protective cover, air pump, dust suction pipe, filter screen and feeding box to form a dust suction and cleaning system, which realizes that while cutting and processing non-woven fabric, it can simultaneously adsorb and remove the generated edge waste and fiber dust, avoiding the problem of having to interrupt the operation for manual cleaning in the traditional process, and significantly improving the continuity of production and the efficiency of equipment use.

[0013] 2. The cooperation of the mounting base, the second sliding rod, the locking block, the third elastic element, and the mounting block ensures a secure installation of the filter screen, preventing it from loosening or falling off during equipment operation.

Detailed Implementation

[0023] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Example 1: Please refer to Figures 1-3An automatic waste suction device for nonwoven fabric processing includes a workbench 1. The workbench 1 has symmetrically arranged fixed plates 2 on its surface for fixing the left and right ends of the nonwoven fabric. A first elastic element 3 connects the fixed plates 2 to the workbench 1, providing a restoring force and clamping pressure for the fixed plates 2. A fixed seat 4 is fixedly connected to the middle of the workbench 1. A cylinder 5 is mounted on the top of the fixed seat 4. A cutting assembly 6 is mounted on the movable rod of the cylinder 5. The cutting assembly 6 is equipped with two cutting heads for cutting the nonwoven fabric. Furthermore, the workbench 1 has symmetrically arranged slots on its surface. When the cutting assembly 6 performs the cutting action, the slots provide space for the cutting heads to move downwards, facilitating the cutting operation of the nonwoven fabric. Four first sliding rods 7 are slidably arranged on the cutting head portion of the cutting assembly 6. A protective cover 8 is provided on the first sliding rods 7, and a dust suction device is installed inside the protective cover 8. The first slide rod 7 is fitted with a second elastic element 9, the upper and lower ends of which are connected to the cutting assembly 6 and the protective cover 8, respectively, so that the protective cover 8 has a downward pressing tendency, thereby pressing down on the end of the non-woven fabric to be cut from above, playing a role in pressing and preventing deviation. The two protective covers 8 are connected to a dust suction pipe 10. The workbench 1 is equipped with a collection box 11, and an air pump 12 is installed on the collection box 11. The input end of the air pump 12 is connected to the protective cover 8 through the dust suction pipe 10, and the output end is connected to the internal space of the collection box 11, forming a complete negative pressure dust suction path. The collection box 11 has a material discharge box 13 for collecting cutting waste. The top of the collection box 11 has an exhaust port, and the top of the exhaust port is equipped with a filter screen 14 to block dust and fine scraps inside the collection box 11 while exhausting air.

[0025] In use, the non-woven fabric to be cut is placed on the worktable 1 and clamped and fixed by the fixing plates 2 on both sides. The first elastic element 3 provides a certain clamping pressure to the fixing plates 2, so that the non-woven fabric remains flat and does not shift during the subsequent cutting process. Then, the cylinder 5 is activated, driving the cutting assembly 6 downward. The cutting assembly 6 drives the two cutting heads to move downward. At the same time, due to the action of the second elastic element 9, the protective cover 8 contacts the surface of the non-woven fabric before the cutting head, pressing it tightly to prevent the material from warping or shifting during the cutting process. The cutting head continues to descend, passes through the protective cover 8, and enters the slot opened on the surface of the worktable 1. The non-woven fabric is cut, which generates dust and small scraps. At this time, the air pump 12 is started, and a negative pressure is formed inside the suction port of the protective cover 8 through the suction pipe 10. The dust and debris generated in the cutting area are sucked into the collection box 11. The filter screen 14 prevents the waste from escaping and exhausts the air, protecting the working environment. The sucked waste finally falls into the discharge box 13 in the collection box 11, which is convenient for regular removal and cleaning, realizing centralized management of waste. After the cutting is completed, the cylinder 5 drives the cutting component 6 to rise and reset. The protective cover 8 is also restored to its original position through the second elastic element 9. The entire device returns to the initial state and waits for the next operation.

[0026] Example 2: Based on Example 1, please refer to... Figure 4 and Figure 5 The top of the material box 13 is fixedly connected to a mounting base 15 symmetrically distributed on both sides. A second slide rod 16 is slidably arranged on the mounting base 15. A locking block 17 is fixedly connected to the bottom end of the second slide rod 16. The locking block 17 has a beveled structure on both its front and rear sides. A third elastic element 18 is sleeved on the second slide rod 16 to provide a downward restoring force for the locking block 17. The upper and lower ends of the third elastic element 18 are fixedly connected to the mounting base 15 and the locking block 17, respectively. The top of the filter screen 14 is fixedly connected to a mounting block 19 symmetrically distributed on both sides. The mounting block 19 has a groove. The mounting block 19 forms a locking engagement with the locking block 17 through the groove. In addition, during the installation process, when the mounting block 19 contacts the locking block 17, the bevel can guide the locking block 17 to slide upward and compress the third elastic element 18, thereby achieving automatic alignment and locking and improving assembly efficiency.

[0027] With the filter screen 14 not installed, the locking block 17 is in a downward-extending position under the action of the third elastic element 18, i.e., a natural locking state. When installing the filter screen 14, the filter screen 14 is moved horizontally to directly above the exhaust port at the top of the collection box 11. During this process, when the mounting block 19 contacts the locking block 17, due to the inclined structure on both sides of the locking block 17, the mounting block 19 will push the locking block 17 to slide upward along the second slide rod 16, while compressing the third elastic element 18. As the mounting block 19 continues to descend, when the mounting block 19 and the locking block 17 are aligned, the locking block 17 will spring back downward under the reset action of the third elastic element 18, accurately locking into the groove on the mounting block 19, completing the locking action. In this way, the filter screen 14 is firmly fixed to the top of the collection box 11, ensuring that it will not loosen or fall off during the operation of the equipment, ensuring the sealing and filtration effect of the collection box 11, and at the same time, facilitating subsequent disassembly and replacement.

[0028] Please see Figure 6 and Figure 7 The top of the collection box 11 is provided with symmetrically distributed electric guide rails 20. The electric guide rails 20 are slidably provided with slide seats 21. The slide seats 21 are provided with cleaning brushes 22. The cleaning brushes 22 are located below the filter screen 14, and their brush heads are in contact with the bottom surface of the filter screen 14.

[0029] During the use of this device, the electric guide rail 20 controls the slide 21 to drive the cleaning brush 22 to reciprocate along the length of the filter screen 14. At this time, the brush head of the cleaning brush 22 sweeps back and forth on the surface of the filter screen 14, removing the fiber dust, fine particles and other impurities attached to the filter screen 14. The removed impurities fall into the material box 13 below and are collected and processed together with the scrap materials sucked in during the cutting process, which facilitates unified recycling and management. This prevents the problem of dust suction failure and production efficiency affected by the clogging of the filter screen 14.

[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
