Description

Technical Field

[0001] This utility model relates to the field of fabric perforation technology, specifically a perforation device for producing mesh fabric. Background Technology

[0002] Mesh fabric, a composite material made of high-strength polyester or nylon as the base fabric, coated with cast PVC slurry on both sides and formed by drying process, is widely used in raincoats, tarpaulins, bags, sun umbrellas, traffic warning signs, special clothing and other fields due to its good insulation performance, strong chemical stability, acid and alkali resistance and certain high and low temperature resistance. With the continuous growth of market demand, the production efficiency and processing quality of mesh fabric have become the focus of industry attention.

[0003] In the production process of mesh fabric, perforation is an important step to meet specific customer needs, such as facilitating subsequent processing or use. However, traditional mesh fabric perforation relies heavily on manual operation, which is not only inefficient but also results in inconsistent perforation quality, making it difficult to guarantee the accuracy and consistency of perforation. In addition, improper handling of waste generated during manual perforation can easily lead to accumulation in the work area, affecting the smooth progress of subsequent perforation operations and increasing the labor intensity of workers.

[0004] The patent titled "A Perforating Device for the Production of Mesh Fabric" (publication number CN211036521U) also raises the issue of manual perforation in the aforementioned content. While it uses an electric drive to move multiple perforating heads to perforate the mesh fabric, the perforating heads are fixed to the lead screw and can only move with the rotation of the lead screw. When circular perforation or array perforation is required, it cannot achieve complex array perforation effects. Therefore, a perforating device for the production of mesh fabric is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a punching device for producing mesh fabric, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a punching device for producing mesh fabric, comprising: a support table, two transmission supports fixedly connected to the support table, mesh fabric being transmitted between the two transmission supports, a fixed frame fixedly connected to the support table, a drive motor fixedly connected to the outside of the fixed frame, the output shaft of the drive motor passing through the outer wall of the fixed frame and fixedly connected to a threaded rod, one end of the threaded rod being rotatably connected to the side of the fixed frame away from the drive motor, a movable connecting seat being threadedly connected to the outside of the threaded rod, and a punching structure fixedly connected below the movable connecting seat;

[0007] The drilling structure includes an electric push rod, which is fixedly connected to the lower part of the transmission support. The piston rod end of the electric push rod is movably connected to a primary connecting seat. A drill chuck is fixedly connected to the lower part of the primary connecting seat. A puncture needle is locked inside the drill chuck. A parallel drilling structure is connected to the outside of the primary connecting seat.

[0008] As a further preferred embodiment of this technical solution: the parallel drilling structure includes a secondary connector located on one side of the primary connector. The secondary connector has multiple second threaded holes on its exterior, and the primary connector has multiple first threaded holes on its exterior. Both the first and second threaded holes are threaded with external threaded connectors. A connecting rod is fixedly connected to one side of two adjacent external threaded connectors.

[0009] As a further preferred embodiment of this technical solution: the connecting rod is a multi-stage telescopic rod, and the outer wall of the multi-stage telescopic rod-shaped connecting rod is all set with a rough surface.

[0010] As a further preferred embodiment of this technical solution: the bottom of the electric push rod is fixedly connected to an external rubber plug-in seat, and the top of both the primary connecting seat and the secondary connecting seat are provided with plug-in slots, and the external rubber plug-in seat is inserted into the inside of the plug-in slots.

[0011] As a further preferred embodiment of this technical solution: a rubber seat is fixedly connected to the support table, and the rubber seat is located below the fixed frame.

[0012] As a further preferred embodiment of this technical solution: an adsorption shell is fixedly connected to the outside of the rubber seat, and the adsorption shell has multiple negative pressure adsorption holes on its outside, and the air outlet of the adsorption shell is connected to a suction pump.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this utility model, the parallel punching structure design enables the device to perform multiple irregular array punching holes. Operators can connect the external threaded connectors at both ends of the connecting rod to the first threaded hole on the outside of the primary connecting seat and the second threaded hole on the outside of the secondary connecting seat, respectively, to connect multiple secondary connecting seats to the primary connecting seat to form an array punching and puncture device. Furthermore, the connecting rod is a multi-stage telescopic rod, allowing adjustment of the distance between the primary and secondary connecting seats to accommodate different punching requirements. Operators can freely adjust the number and position of multiple puncture needles according to actual needs, meeting the requirements of different punching effects on the mesh fabric, thus enhancing the versatility and flexibility of the device.

[0016] 2. In this utility model, a rubber seat is provided under the fixed frame on the support table. When punching holes in the mesh fabric, the rubber seat provides downward movement space for the puncture needle, ensuring that the puncture needle can completely puncture the mesh fabric, guaranteeing the completion rate of puncture.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Example 1

[0026] Please see Figures 1-6 This utility model provides a technical solution: a punching device for producing mesh fabric, comprising: a support table 1, two transmission supports 2 fixedly connected to the support table 1, mesh fabric being transmitted between the two transmission supports 2, a fixed frame 3 fixedly connected to the support table 1, a drive motor 4 fixedly connected to the outside of the fixed frame 3, the output shaft of the drive motor 4 passing through the outer wall of the fixed frame 3 and fixedly connected to a threaded rod 5, one end of the threaded rod 5 being rotatably connected to the side of the fixed frame 3 away from the drive motor 4, a movable connecting seat 17 being threadedly connected to the outside of the threaded rod 5, and a punching structure being fixedly connected to the bottom of the movable connecting seat 17;

[0027] The drilling structure includes an electric push rod 7, which is fixedly connected to the lower part of the transmission support 2. The piston rod end of the electric push rod 7 is movably connected to a primary connecting seat 8. A drill chuck 9 is fixedly connected to the lower part of the primary connecting seat 8. A puncture needle 10 is locked inside the drill chuck 9. A parallel drilling structure is connected to the outside of the primary connecting seat 8.

[0028] In this embodiment, specifically: during use, the operator places the mesh fabric between two transmission supports 2 for transmission, and passes the mesh fabric through the center of the fixed frame 3. While the mesh fabric is being transmitted by the two transmission supports 2, the operator can start the drive motor 4 to drive the threaded rod 5 to rotate. When the threaded rod 5 rotates, it can drive the movable connecting seat 17 to move. After the movable connecting seat 17 moves to the designated position above the mesh fabric, the electric push rod 7 is started to drive the first-stage connecting seat 8 to move down. Thus, the first-stage connecting seat 8 drives the drill bit clamp 9 and the piercing needle 10 to pierce and punch holes in the mesh fabric, completing the automatic punching process of the mesh fabric.

[0029] In this embodiment, specifically: the fixed frame 3 is fixedly connected to both sides of the movable connecting seat 17 with through rods 6. The through rods 6 penetrate the outer wall of the movable connecting seat 17, and the movable connecting seat 17 is slidably connected to the outside of the through rods 6. When the movable connecting seat 17 is moving, in order to prevent the threaded rod 5 from causing the movable connecting seat 17 to rotate, the through rods 6 pass through the movable connecting seat 17 to limit and guide the movable connecting seat 17, so as to prevent the movable connecting seat 17 from rotating with the threaded rod 5 during the rotation process.

[0030] like Figures 1-3 As shown, the parallel perforated structure includes a secondary connector 13 located on one side of the primary connector 8. The secondary connector 13 has multiple second threaded holes 14 on its exterior, and the primary connector 8 has multiple first threaded holes 11 on its exterior. The first threaded holes 11 and the second threaded holes 14 are all threaded with external threaded connectors 22. A connecting rod 12 is fixedly connected to one side of the two external threaded connectors 22 that are adjacent to each other.

[0031] In this embodiment, specifically: during use, when it is necessary to punch multiple holes in an irregular array on the mesh fabric, the operator can connect the secondary connecting seat 13 and the primary connecting seat 8 through the connecting rod 12, thereby connecting multiple secondary connecting seats 13. Furthermore, puncture needles 10 are installed together below the multiple secondary connecting seats 13 through the drill clamp 9, thus forming an array punching and puncturing device. When facing the need for array punching, the operator can freely adjust the number and position of the multiple puncture needles 10 according to the requirements, so as to facilitate different punching effects on the mesh fabric.

[0032] like Figure 5 As shown, the connecting rod 12 is a multi-stage telescopic rod, and the outer wall of the multi-stage telescopic rod 12 is all roughened.

[0033] In this embodiment, specifically: during use, when the connecting rod 12 is a multi-stage telescopic rod, it is convenient for the staff to adjust the distance between the first-stage connecting seat 8 and the second-stage connecting seat 13, so that multiple puncture needles 10 may also be at different distances. When different distances are formed, it is convenient to meet the punching requirements of different distances of the mesh fabric, and to adapt to the punching method of the mesh fabric in a more diversified way.

[0034] like Figure 3 As shown, the bottom of the electric push rod 7 is fixedly connected to an outer rubber plug-in seat 15. The top of the primary connecting seat 8 and the secondary connecting seat 13 are both provided with plug-in slots 16, and the outer rubber plug-in seat 15 is inserted into the inside of the plug-in slot 16.

[0035] In this embodiment, specifically: when connecting the electric push rod 7 to the primary connecting seat 8, the operator can insert the outer rubber plug 15 into the insertion slot 16. When the outer rubber plug 15 is inserted into the insertion slot 16, the piston rod end of the electric push rod 7 can be connected to the primary connecting seat 8. A rubber ring is connected to the outside of the outer rubber plug 15, so that the rubber ring will deform when the outer rubber plug 15 is inserted into the insertion slot 16. The rubber ring and the outer rubber plug 15 are interference-fitted into the insertion slot 16, making the overall insertion method more stable and convenient for disassembly. In addition, the operator can also energize the insertion slot 16 during use, so that the insertion slot 16 generates magnetism and continuously attracts the outer rubber plug 15, ensuring the connection stability between the outer rubber plug 15 and the insertion slot 16.

[0036] Example 2

[0037] To ensure the perforation requirements of the mesh fabric during production, such as circular array perforation or other perforation methods, existing single perforation plates cannot meet the load-bearing capacity of randomly changing perforation orientations. Therefore, to address the aforementioned technical problem, this application proposes the following technical solution:

[0038] like Figure 1 and Figure 6 As shown, a rubber seat 18 is fixedly connected to the support table 1, and the rubber seat 18 is located below the fixed frame 3.

[0039] In this embodiment, specifically: when perforating the mesh fabric, a rubber seat 18 is used to support the bottom surface of the mesh fabric. After the upper puncture needle 10 punctures the mesh fabric, the tip of the puncture needle 10 is immediately inserted into the interior of the rubber seat 18, providing room for the puncture needle 10 to move downwards. This ensures that the puncture needle 10 can completely puncture the mesh fabric when it is pressed down, guaranteeing the completion rate of the puncture. When using the rubber seat 18, regardless of where the puncture needle 10 is punctured, it can provide room for the puncture needle 10 to move downwards, and providing room for the puncture needle 10 to move downwards will not affect the supporting effect on the mesh fabric.

[0040] like Figures 1-6 As shown, an adsorption shell 19 is fixedly connected to the outside of the rubber base 18. Multiple negative pressure adsorption holes 20 are opened on the outside of the adsorption shell 19, and the air outlet of the adsorption shell 19 is connected to a suction pump 21.

[0041] In this embodiment, specifically: when puncturing the mesh fabric, the gas inside the adsorption shell 19 can be extracted by starting the suction air pump 21, and when the mesh fabric is placed on the adsorption shell 19, the negative pressure adsorption hole 20 can form a negative pressure suction effect on the mesh fabric, thereby ensuring the stability of the mesh fabric during puncture.

[0042] Working principle: The operator first places the mesh fabric between the two transmission supports 2. The transmission supports drive the mesh fabric to pass through the center of the fixed frame 3. Then, the drive motor 4 outside the fixed frame 3 is started. The output shaft of the drive motor 4 drives the threaded rod 5 to rotate. When the moving connecting seat 17 reaches the designated position, the electric push rod 7 is started, which drives the first-stage connecting seat 8 to move down. The drill chuck 9 below the first-stage connecting seat 8 drives the piercing needle 10 to pierce and punch holes in the mesh fabric.

[0043] Meanwhile, if multiple holes and irregular array drilling are required, the operator can use the external threaded connectors 22 at both ends of the connecting rod 12 to connect to the first threaded hole 11 on the outside of the primary connecting seat 8 and the second threaded hole 14 on the outside of the secondary connecting seat 13 respectively, so as to connect multiple secondary connecting seats 13 with the primary connecting seat 8 to form an array drilling and puncture device. The connecting rod 12 is a multi-stage telescopic rod, which can adjust the distance between the primary connecting seat 8 and the secondary connecting seat 13 to adapt to the drilling requirements of different distances. The puncture needle 10 is also installed under the secondary connecting seat 13 through the drill chuck 9 for drilling.

[0044] A rubber seat 18 is provided below the fixed frame 3 on the support table 1. When the puncture needle 10 presses down to puncture the mesh, the rubber seat 18 provides space for the puncture needle 10 to move downward, ensuring that the puncture needle 10 completely punctures the mesh. At the same time, multiple negative pressure suction holes 20 are opened on the external suction shell 19 of the rubber seat 18. The air outlet of the suction shell 19 is connected to the suction pump 21. When punching holes, the suction pump 21 is started, and a negative pressure suction effect is formed on the mesh through the negative pressure suction holes 20, ensuring the stability of the mesh during puncture, thereby completing the automatic punching process of the mesh.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
