Description

Technical Field

[0001] This utility model relates to the field of tarpaulin processing technology, specifically to a tarpaulin punching and ring pressing machine. Background Technology

[0002] Tarpaulin is a high-strength, waterproof material with good toughness and softness. Tarpaulins usually have sturdy slings at the corners or edges to facilitate the threading of ropes for binding, hanging, or covering. When installing slings, it is necessary to first use a hole punching device to make holes at the edges of the tarpaulin.

[0003] Existing tarpaulin punching and ring-pressing machines, such as the invention patent document with authorization announcement number "CN213532908U" and patent name "An Automatic Punching Device for Tarpaulin Production," disclose a tarpaulin punching and ring-pressing machine, including an operating table. A mounting frame is fixedly connected to the upper end of the operating table, and a U-shaped block is fixedly connected to the rear end of the mounting frame. A first motor is fixedly connected to the upper end of the operating table, and a second pulley is fixedly connected to the output end of the first motor. A first mounting block is fixedly connected to the upper end of the operating table. A first rotating shaft is rotatably connected to the front end of the first mounting block, and the first rotating shaft movably passes through the first mounting block and extends to the outside of the first mounting block. A first pulley is fixedly connected to the front end of the first rotating shaft, and a belt drives the second pulley to the first pulley. A turntable is fixedly connected to the rear end of the first rotating shaft, and a fifth rotating shaft is rotatably connected to the rear end of the turntable. A first connecting block is rotatably connected to the rear end of the fifth rotating shaft, and a fourth rotating shaft is rotatably connected to the rear end of the first connecting block.

[0004] In the aforementioned patent document, when it is necessary to punch holes in the tarpaulin, the device has a relatively fixed position for punching holes in the tarpaulin. If the position of the holes in the tarpaulin is to be changed, the tarpaulin needs to be pulled and moved manually. However, manual operation to position the continuous holes reduces the processing accuracy and efficiency. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a tarpaulin punching and pressing ring machine. This machine solves the technical problem mentioned in the background art: when punching tarpaulins, the existing tarpaulin punching and pressing ring machine has a relatively fixed punching position. If the punching position of the tarpaulin is to be changed, the tarpaulin needs to be manually pulled and moved. However, manual operation to position the continuous punching positions reduces processing accuracy and efficiency.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: it includes a mounting frame, on both sides of the mounting frame are respectively rotatably provided first rotating rollers, a fixed seat is fixed on the mounting frame and the fixed seat is located between the two first rotating rollers, the fixed seat is provided with a strip-shaped hole, and on both sides of the mounting frame are respectively slidably provided movable frames that can move relative to each other, each of the two movable frames is provided with a buckle assembly for punching and pressing rings on the tarpaulin, and the mounting frame is provided with a drive assembly for driving the two movable frames to move relative to each other.

[0007] Working principle:

[0008] The tarpaulin to be processed covers and passes through two parallel first rotating rollers. The fixed seat is located between the two first rotating rollers, and its strip hole provides an operating window. The tarpaulin covers the fixed seat and is exposed to the strip hole area. When tarpaulins of different widths need to be processed, the drive component is activated. The drive component drives two moving frames installed on both sides of the mounting frame to move relative to each other. The sliding of the moving frames drives the buckle assembly installed on them to move synchronously. When the moving frames and buckle assembly are positioned at the target position, the buckle assembly starts to work. Since the tarpaulin covers the fixed seat and its strip hole, the buckle assembly uses the fixed seat as the lower support base. The two buckle assemblies perform punching and ring pressing operations simultaneously. After completing the punching and ring pressing operation at the current point, the tarpaulin can be pulled by an external fabric rolling machine. When the tarpaulin moves to the next processing position, the buckle assembly performs punching and ring pressing operations again. This cycle continues until the continuous punching and buckle installation of the entire roll of tarpaulin at the edge or a specific position is completed.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] First, it is equipped with a drive component, which controls the relative movement of two moving frames and allows for flexible adjustment of the spacing of the buckle components to accommodate tarpaulins of different widths.

[0011] Secondly, it is equipped with a buckle assembly, which can be used to punch holes and press rings into the tarpaulin. Attached Figure Description

Detailed Implementation

[0016] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0017] Example:

[0018] like Figure 1 and Figure 2 As shown, a tarpaulin punching and ring pressing machine includes a mounting frame 1. First rotating rollers 2 are rotatably mounted on both sides of the mounting frame 1. A fixed seat 3 is fixedly mounted on the mounting frame 1, located between the two first rotating rollers 2. A strip-shaped hole 4 is formed in the fixed seat 3. Relative movable frames 5 are slidably mounted on both sides of the mounting frame 1. A drive assembly for driving the relative movement of the two movable frames 5 is provided on the mounting frame 1. The drive assembly includes a second motor 16, a bidirectional screw 17, two sliding blocks 18, and a guide rod 19. The second motor 16 is fixedly mounted on the mounting frame 1. The bidirectional screw 17 is rotatably mounted on the mounting frame 1, with one end of the bidirectional screw 17 fixedly connected to the output end of the second motor 16. The two sliding blocks 18 are respectively fixed on the two movable frames 5 and respectively screwed to the bidirectional screw 19. On the two threaded sections of the screw 17, the guide rod 19 is fixed on the mounting frame 1, and the two sliding blocks 18 are slidably mounted on the guide rod 19. The tarpaulin is introduced from one side of the machine, laid flat on the two first rotating rollers 2, and covers the fixed seat 3. It is then wound around the external winding machine used to pull the tarpaulin. The winding machine is existing technology and will not be described in detail here. When it is necessary to adjust the punching position, the second motor 16 is started to drive the bidirectional screw 17 to rotate. Since the threads at both ends of the screw rotate in opposite directions, the two sliding blocks 18 connected to it by the thread will move in opposite directions or in a straight line along the guide rod 19. The sliding blocks 18 are fixedly connected to the moving frame 5, thereby driving the two moving frames 5 and the entire buckling assembly on them to move closer or further away synchronously, so as to realize the positioning of the hole position on the edge of the tarpaulin of different widths.

[0019] like Figure 1 and Figure 2As shown, both movable frames 5 are equipped with buckle-fastening assemblies for punching and fastening rings on the tarpaulin. Each buckle-fastening assembly includes a sliding plate 6, a lower punch head 7, a guide rod 8, a mounting plate 9, a spring 10, and an upper punch head 11. A groove 12 is provided on the fixed base 3. The sliding plate 6 is slidably disposed within the groove 12. The lower punch head 7 is slidably disposed on the sliding plate 6 and extends outward through the strip-shaped hole 4. The guide rod 8 is fixed to the movable frame 5, and the mounting plate 9 is fixed to the end of the lower punch head. Mounting plate 9 is slidably mounted on guide rod 8. Spring 10 is sleeved on the outer ring of lower punch head 7, and both ends of spring 10 are fixedly connected to sliding plate 6 and mounting plate 9 respectively. Upper punch head 11 is slidably mounted on moving frame 5. Cavity 25 is opened in lower punch head 7, and the bottom of upper punch head 11 can slide through into cavity 25. First cylinder 13 is fixed on moving frame 5, upper punch head 11 is fixed on the extension end of first cylinder 13, and first motor 14 is fixed on moving frame 5. The output end of first motor 14 is... A cam 15 is fixedly mounted on the upper part of the tarpaulin and abuts against the mounting plate 9. After the tarpaulin is positioned, the first motor 14 starts and drives the cam 15 to rotate. The protruding part of the cam 15 pushes the mounting plate 9, and the mounting plate 9 slides along the guide rod 8, compressing the spring 10 and pushing the lower punch head 7 toward the upper punch head 11. Immediately afterwards, the first cylinder 13 is activated, and its telescopic end pushes the upper punch head 11 toward the lower punch head 7. The bottom of the upper punch head 11 slides into the cavity 25 of the lower punch head 7. During this process, the upper and lower punch heads 7 work together to punch holes in the tarpaulin. The buckle on the end of the upper punch head 11 is punched onto the tarpaulin and is tightly fixed to the tarpaulin. After the punching is completed, the first cylinder 13 retracts, driving the upper punch head 11 to reset. At the same time, the first motor 14 continues to rotate, and the protruding part of the cam 15 rotates. At this time, the compressed spring 10 releases its elastic potential energy, pushing the mounting plate 9 and the lower punch head 7 to reset, preparing for the next punching.

[0020] like Figure 1 and Figure 3 As shown, two symmetrically arranged strip grooves 20 are opened on both sides of the mounting frame 1. Movable blocks 21 are slidably arranged in multiple strip grooves 20. Second rollers 22 are rotatably arranged between multiple pairs of movable blocks 21. The two second rollers 22 are respectively located above the two first rollers 2. Threaded rods 26 are rotated on multiple pairs of movable blocks 21 and multiple threaded rods 26 are threadedly connected to the mounting frame 1. By rotating the threaded rods 26, the movable blocks 21 can be driven to slide vertically in the strip grooves 20, thereby adjusting the height of the two second rollers 22. The second rollers 22 are located above the first rollers 2. Together, they form a conveying clamping roller channel. Adjusting this height can accommodate tarpaulins of different thicknesses and provide appropriate clamping force to prevent slippage during conveying.

[0021] like Figure 1 and Figure 2As shown, a second cylinder 23 is provided between each of the two first rotating rollers 2 and the fixed base 3, and the two second cylinders 23 are fixed on the mounting frame 1. An adjusting roller 24 for adjusting the tension of the tarpaulin is rotatably provided on the telescopic end of each of the two second cylinders 23. The telescopic end of the second cylinder 23 can lift or lower the adjusting roller 24. When the tarpaulin passes under the adjusting roller 24 from the first rotating roller 2 and then moves to the fixed base 3, the height of the adjusting roller 24 can be changed by controlling the stroke of the cylinder, thereby tightening or loosening the tarpaulin so that it remains flat and has appropriate tension when punching holes.

[0022] Working principle:

[0023] The tarpaulin is first fed into the conveying channel consisting of the first rotating roller 2 and the height-adjustable second rotating roller 22. The adjusting roller 24 driven by the second cylinder 23 tensions the tarpaulin to ensure flatness. Then, the second motor 16 is started, driving the bidirectional screw 17 to rotate, causing the two moving frames 5 to move towards or away from each other along the guide rod 19, positioning the upper punch head 11 and the lower punch head 7 to the target processing position of the tarpaulin. After positioning, the first motor 14 is started, driving the cam 15, which pushes the lower punch head 7 through the mounting plate 9 and the spring 10 through the strip hole 4 of the fixed seat 3. Immediately afterwards, the first cylinder 13 pushes the upper punch head 11, and its bottom is inserted into the cavity 25 of the lower punch head 7. The buckle, which is movably fitted on the end of the upper punch head 11, is punched onto the tarpaulin and tightly fixed together with the tarpaulin, together completing the punching and buckle pressing. After completion, all components are reset, and the tarpaulin is wound up by an external winding machine.
