[0020] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0021] Please see Figures 1-5 This utility model provides a technical solution:

[0022] An automatic positioning tarpaulin punching device includes a frame assembly 1, roller assemblies 2 installed on both sides of the frame assembly 1, a drilling assembly 3 installed in the frame assembly 1, roller assembly 2 including two columns, two vertically parallel rollers fixedly connected between the two columns, a first roller 26 and a second roller 27 respectively sleeved on the two rollers, and a positioning structure provided between the first roller 26 and the columns.

[0023] The frame assembly 1 comprises a panel 11, four supporting legs 12 fixedly connected to the four corners of the bottom of the panel 11, and four supporting rods 13 fixedly connected to the four corners of the top of the panel 11. The top of each supporting rod 13 is provided with an arc-shaped groove 15, and a first roller shaft 14 is arranged in each arc-shaped groove 15. A tarpaulin 16 is wound around the left first roller shaft 14, and the right first roller shaft 14 is coaxially fixedly connected to the output shaft of a first motor 17. A supporting column 18 is fixedly installed at the bottom of the first motor 17. The four supporting legs 12 stably support the panel 11, and the two ends of the first roller shaft 14 are arranged in the arc-shaped grooves 15 at the top of the two supporting rods 13. During operation, the tarpaulin 16 to be drilled is sleeved on the left first roller shaft 14, and then the other end of the tarpaulin 16 is fixedly arranged on the right first roller shaft 14. When the first motor 17 is started and drives the right first roller shaft 14 to rotate, the tarpaulin 16 will be gradually wound on the right first roller shaft 14, which will simultaneously drive the left first roller shaft 14 to smoothly rotate in the arc-shaped groove 15. In addition, the design of the arc-shaped groove 15 not only ensures the stable installation of the first roller shaft 14, but also facilitates the replacement of different first roller shafts 14 to replace the new tarpaulin 16 and continue the next round of drilling operation.

[0024] The stand comprises a first stand 21 and a second stand 22. The second stand 22 is arranged on the top surface of the panel 11, and the first stand 21 is installed on the second stand 22. The second stand 22 is provided with a sliding groove for the first stand 21 to slide up and down. A bolt 23 is installed on the side of the second stand 22 close to the drilling assembly 3.

[0025] The roller shaft comprises a second roller shaft 24 and a third roller shaft 25. The second roller shaft 24 is fixedly installed between the two first stands 21, and a first roller drum 26 is rotatably sleeved on the second roller shaft 24. The third roller shaft 25 is fixedly installed between the second stands 22, and a second roller drum 27 is rotatably sleeved on the third roller shaft 25.

[0026] It is to be noted that the tarpaulin 16 is first hung on the first roller 14 on the left side of the device, then one end of the tarpaulin 16 passes through the gap between the first roller 26 and the corresponding second roller 27, and is finally fixed on the first roller 14 on the right side of the device. When the first motor 17 is started, it drives the first roller 14 on the right side to start rotating. With the rotation of the first roller 14, the tarpaulin 16 is gradually and uniformly wound on the first roller 14 on the right side. During this process, the movement of the tarpaulin 16 naturally drives the first roller 26 to rotate, so that the positioning holes 29 on both sides of the first roller 26 rotate.

[0027] It is to be noted that the roller assembly 2 is designed with a positioning pin 28, which is composed of two nested rods, a spring is installed in the thick rod, and the spring is fixedly connected with the thin rod, and the other end of the thin rod is a hemisphere. The positioning hole 29 is an arc-shaped hole matched with the hemisphere of the positioning pin 28. During the rotation of the first roller 26, the thin rod of the positioning pin 28 is always attached to its cross section under the action of the spring, and when the positioning pin 28 and the positioning hole 29 are opposite, the thin rod of the positioning pin 28 and the hemisphere at the end thereof are pushed into the positioning hole 29 under the action of the spring, achieving positioning. During the continuous rotation of the first roller 26, since the positioning hole 29 is an arc-shaped hole, the hole wall will extrude the hemisphere of the positioning pin 28, prompting it to move back, so as to be separated from the positioning hole 29.

[0028] It is to be noted that an insulating sticker is arranged in the positioning hole 29, the hemisphere at the end of the positioning pin 28 and the first roller 26 are both conductive metal materials, the hemisphere at the end of the positioning pin 28, the first roller 26, the first motor 17 and the power supply arranged on the frame assembly 1 are connected in series through wires, when the positioning pin 28 moves on the surface of the first roller 26 without the positioning hole 29, the hemisphere thereon contacts the surface of the first roller 26, so as to conduct the series circuit composed of the hemisphere at the end of the positioning pin 28, the first roller 26, the first motor 17 and the power supply arranged on the frame assembly 1, and the first motor 17 normally supplies power to rotate, when the positioning pin 28 moves into the positioning hole 29, the series circuit composed of the hemisphere at the end of the positioning pin 28, the first roller 26, the first motor 17 and the power supply arranged on the frame assembly 1 is disconnected under the action of the insulating sticker, the first motor 17 stops working, and the first roller 14 stops rotating, so as to stop the movement of the tarpaulin 16. Manually open the switch, the first motor 17 resumes power supply and continues to rotate until the positioning pin 28 enters the next positioning hole 29 and stops rotating.

[0029] The drilling assembly 3 comprises two support plates 31 fixedly installed on the top surface of the panel 11 and located on both sides of the panel 11, a top cover 32 fixedly installed in the two support plates 31 and located on the top of the support plates 31, a pad plate 33 installed between the two support plates 31 and fixedly connected with the top surface of the panel 11, and a recess 34 provided on the pad plate 33 and used for inserting the drilling bit 38. The top cover 32 is fixedly installed with a pneumatic cylinder 37, the bottom end of the piston rod of the pneumatic cylinder 37 is fixedly installed with a second motor 36, and the output shaft of the second motor 36 is fixedly connected with the drilling bit 38. When the pneumatic cylinder 37 is started, it will start to drive the second motor 36 to descend, thereby driving the drilling bit 38 to descend. The drilling bit 38 will gradually approach the tarpaulin 16 on the pad plate 33 in the descending process. When the drilling bit 38 contacts the tarpaulin 16, the drilling bit 38 will continue to descend and complete the punching operation on the tarpaulin 16 under the continuous action of the second motor 36 and the pneumatic cylinder 37. This process will continue until the drilling bit 38 completely enters the preset recess 34. Then the pneumatic cylinder 37 drives the second motor 36 and the drilling bit 38 to ascend, thereby completing a punching operation and preparing for the next punching.

[0030] It should be noted that the height of the pad plate 33 is the same as the height of the second roller 27, and when one end of the tarpaulin 16 passes through the gap reserved between the two first rollers 26 and the corresponding second roller 27, the middle of the tarpaulin 16 will be supported by the pad plate 33.

[0031] In specific operation, the tarpaulin 16 to be drilled is sleeved on the first roller 14 on the left side, then one end of the tarpaulin 16 passes through the gap reserved between the two first rollers 26 and the corresponding second roller 27, the middle of the tarpaulin 16 is supported by the pad plate 33, and finally is fixed on the first roller 14 on the right side of the device.

[0032] Then, by loosening the bolt 23, the position of the first column 21 in the sliding groove of the second column 22 can be adjusted flexibly. In this step, the movement of the first column 21 will drive the second roller 24 mounted thereon and the first roller 26 sleeved on the second roller 24 to move correspondingly. When it is observed that the first roller 26 closely abuts against the second roller 27 and compresses the tarpaulin 16, it indicates that the ideal compression state has been reached. At this time, only the bolt 23 needs to be tightened again to firmly fix the position of the first column 21, thereby ensuring that the entire tarpaulin 16 maintains stable tension and position during the punching or subsequent processing process. The first motor 17 is started to drive the tarpaulin 16 to move, and in the movement process, the first roller 26 will rotate, and the rotation of the first roller 26 will promote the positioning pin 28 to be in contact with the discontinuous section of the first roller 26 and the positioning hole 29. In the process of contacting the discontinuous section of the first roller 26, the first motor 17 is in the working state, and in the process of contacting the positioning hole 29, the first motor 17 is in the closed state. Since the distance between the two adjacent positioning holes 29 is specific, the above process will realize the uninterrupted movement and stopping process of the tarpaulin 16, and can ensure that the distance of the tarpaulin 16 moving forward each time is specific. In this way, the effect of punching every specific distance on the surface of the tarpaulin 16 can be realized, thereby realizing the effect of automatic positioning and punching on the surface of the tarpaulin 16.

[0033] When the tarpaulin 16 is in the stopped state, the cylinder 37 is manually started, which will start to drive the second motor 36 to descend, thereby driving the drill bit 38 to descend. In the process of descending, the drill bit 38 will gradually approach the tarpaulin 16 on the pad 33. When the drill bit 38 contacts the tarpaulin 16, under the continuous action of the second motor 36 and the cylinder 37, the drill bit 38 will continue to descend and complete the punching operation on the tarpaulin 16. This process will continue until the drill bit 38 completely enters the pre-set recess 34. Then, the cylinder 37 drives the second motor 36 and the drill bit 38 to rise, completing a punching operation and preparing for the next punching.

[0034] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above with a preferred embodiment, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the above-mentioned technical content without departing from the technical solution of the present application, and any equivalent embodiments with equivalent changes and modifications made on the basis of the technical essence of the present application to the above-mentioned embodiments are still within the scope of the technical solution of the present application.
