Description

Technical Field

[0001] This application relates to the field of camouflage tarpaulin technology, and more particularly to a stretching and cutting device for camouflage tarpaulins. Background Technology

[0002] Camouflage tarpaulins are functional protective materials with environmental blending capabilities. Their function is to create visual or infrared concealment effects between the covered object and the surrounding environment, such as jungles, deserts, and snowfields, through special color coatings, pattern designs, or material properties. They are widely used in scenarios such as military equipment protection, field equipment covering, and temporary material storage. These tarpaulins are usually made of high-strength polyester fibers or PVC composite materials and have properties such as tear resistance, water resistance, and UV resistance to adapt to complex outdoor environments.

[0003] During the production of camouflage tarpaulins, they need to be cut into certain sizes to facilitate subsequent processing. Chinese Patent No. CN221072017U discloses a cutting device for tent fabric production. This utility model includes a frame, a conveyor belt, a vertical translation component, a horizontal cutting component, and a vertical cutting component. The conveyor belt is set on the frame. The vertical translation component includes a motor, a screw, and a support base. The motor and the support base are fixed to the lower end of the vertical support of the frame. The cutting size can be quickly changed through the vertical translation component and the cylinder, which improves the cutting efficiency.

[0004] However, in the aforementioned patent, the tarpaulin needs to be fed by a conveyor belt before cutting. However, the conveyor belt is prone to slipping when feeding the tarpaulin, and improper feeding can easily cause wrinkles in the tarpaulin, making it difficult to straighten it. When cutting to the wrinkled part of the tarpaulin, the cut will be uneven, which will affect the cutting quality of the tarpaulin. Therefore, in order to solve the above problems, we provide a straightening and cutting device for camouflage tarpaulins. Summary of the Invention

[0005] The purpose of this utility model is to provide a stretching and cutting device for camouflage tarpaulins, in order to solve the problem mentioned in the background art that currently, before cutting tarpaulins, it is necessary to feed the tarpaulins with a conveyor belt. However, the conveyor belt is prone to slipping when feeding the tarpaulins, and improper feeding can easily cause wrinkles in the tarpaulins, making it difficult to stretch them out. When cutting to the wrinkled areas of the tarpaulins, the cut edge of the tarpaulins will be uneven, which will affect the cutting quality of the tarpaulins.

[0006] The embodiments of this application adopt the following technical solutions: A camouflage tarpaulin stretching and cutting device includes a cutting table, a support plate fixedly installed on one side of the cutting table, a transmission cutting assembly fixedly installed on one side of the support plate, a support cover fixedly connected to one side of the cutting table, a lower slide rail fixedly connected to the inner bottom wall of the support cover, a movable component disposed above the lower slide rail, a support top plate disposed above the movable component, an electric cylinder fixedly installed on the upper surface of the support top plate, a lower stretching plate fixedly installed at the telescopic end of the electric cylinder, the movable component including a movable support plate fixedly installed on the bottom surface of the support top plate, a servo motor fixedly installed on one side of the movable support plate, a drive wheel fixedly installed at the output end of the servo motor, and the bottom surface of the drive wheel rollingly connected to the outer surface of the lower slide rail.

[0007] Preferably, the transmission cutting assembly includes a transmission slide fixedly mounted on the upper surface of a support plate, a forward and reverse motor fixedly mounted on one side of the transmission slide, a transmission lead screw fixedly mounted on the output end of the forward and reverse motor, a lead screw nut slider rollingly connected to the outer surface of the lead screw, the outer surface of the lead screw nut slider slidingly connected to the inner wall of the transmission slide, a movable plate fixedly mounted on the bottom surface of the lead screw nut slider, a drive motor fixedly mounted on one side of the movable plate, and a cutting blade fixedly mounted on the output end of the drive motor.

[0008] Preferably, the upper surface of the cutting table is provided with a cutting groove, and the bottom end of the cutting blade is located inside the cutting groove.

[0009] Preferably, an upper slide rail is fixedly connected to the upper surface of the support cover, a limiting slider is fixedly connected to the bottom surface of the support top plate, the inner wall of the limiting slider is slidably connected to the outer surface of the upper slide rail, and a limiting slide plate is fixedly connected to the upper surface of the lower stretching flat plate, the outer surface of the limiting slide plate is slidably connected to the inner wall of the support top plate.

[0010] Preferably, a bearing ring is fixedly embedded on one side of the movable support plate, the inner ring of the bearing ring is connected to the outer surface of one end of the drive wheel, and two bearing rings are fixedly installed on the inner wall of the transmission slide, with the inner rings of the two bearing rings being fixedly connected to the outer surfaces of both ends of the transmission screw.

[0011] Preferably, two feeding plates are fixedly connected to one side of the cutting table. The upper surface of each feeding plate is provided with a feeding hole, and a reinforcing rod is fixedly connected to the side of the two feeding plates that are close to each other.

[0012] The above-described technical solutions adopted in the embodiments of this application can achieve the following beneficial effects: 1. This camouflage tarpaulin stretching and cutting device pulls one end of the tarpaulin roll to the top of the lower stretching carrier plate. Activation of an electric cylinder causes the cylinder's extension end to lift the lower stretching carrier plate. The support top plate, in conjunction with the lower stretching carrier plate, securely fixes one end of the tarpaulin. This clamping fixing method replaces the friction feeding of traditional conveyor belts, solving the problem of unstable feeding caused by conveyor belt slippage. Subsequently, the servo motor in the moving component starts, driving the drive wheel to roll along the lower track, which in turn moves the moving support plate and the upper support top plate smoothly. As the support top plate moves, it exerts a continuous and uniform pulling force on the tarpaulin, fully stretching it flat. This solves the problem of wrinkling in traditional feeding methods and improves the pre-treatment quality of the tarpaulin before cutting.

[0013] 2. This camouflage tarpaulin stretching and cutting device uses a forward and reverse motor to drive the rotation of the transmission screw, which allows the screw nut slider to slide along the inner wall of the transmission slide block, thereby driving the moving plate to move smoothly. At the same time, the drive motor on the moving plate drives the cutting blade to rotate at high speed, which can cut the stretched tarpaulin below. After cutting, it is easy to reset it, which is convenient for subsequent stretching of the tarpaulin. Therefore, by repeating the process of fixing, stretching and cutting, continuous cutting of camouflage tarpaulin can be achieved, replacing the intermittent and unstable feeding of traditional conveyor belts, reducing manual intervention, and improving the overall cutting efficiency.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Example 1

[0017] As attached Figures 1-5 The device shown is a camouflage tarpaulin stretching and cutting device, including a cutting table 1, a support plate 2 fixedly installed on one side of the cutting table 1, a transmission cutting assembly 3 fixedly installed on one side of the support plate 2, a support cover 4 fixedly connected to one side of the cutting table 1, a lower slide rail 7 fixedly connected to the inner bottom wall of the support cover 4, a movable component 6 arranged above the lower slide rail 7, a support top plate 9 arranged above the movable component 6, an electric cylinder 10 fixedly installed on the upper surface of the support top plate 9, a lower stretching and flattening plate 11 fixedly installed at the telescopic end of the electric cylinder 10, and silicone anti-slip layers provided on the sides of the lower stretching and flattening plate 11 and the support top plate 9 that are close to each other. The movable component 6 includes a support... A movable support plate 14 is fixedly installed on the bottom surface of the top plate 9. A servo motor 61 is fixedly installed on one side of the movable support plate 14. A drive wheel 63 is fixedly installed on the output end of the servo motor 61. The bottom surface of the drive wheel 63 is in rolling connection with the outer surface of the lower slide rail 7. Specifically, by pulling one end of the tarpaulin roll above the lower stretch flat carrier plate 11, and by starting the electric cylinder 10, the telescopic end of the electric cylinder 10 can drive the lower stretch flat carrier plate 11 to rise. The tarpaulin is firmly fixed by the cooperation between the supporting top plate 9 and the lower stretch flat carrier plate 11. This clamping fixing method replaces the friction feeding of the traditional conveyor belt and solves the problem of unstable feeding caused by conveyor belt slippage. Example 2

[0018] Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below, with reference to the specific working method described in detail: In this embodiment, the transmission cutting assembly 3 includes a transmission slide 31 fixedly mounted on the upper surface of the support plate 2. A forward and reverse motor 32 is fixedly mounted on one side of the transmission slide 31. A transmission lead screw 36 is fixedly mounted on the output end of the forward and reverse motor 32. A lead screw nut slider 33 is rolledly connected to the outer surface of the lead screw 36. The outer surface of the lead screw nut slider 33 is slidably connected to the inner wall of the transmission slide 31. A moving plate 34 is fixedly mounted on the bottom surface of the lead screw nut slider 33. A drive motor 35 is fixedly mounted on one side of the moving plate 34. A cutting blade is fixedly mounted on the output end of the drive motor 35. The upper surface of the cutting table 1 has a cutting groove 5. The bottom end of the cutting blade 38 is located inside the cutting groove 5. Furthermore, after the forward and reverse motor 32 of the transmission slide 31 is started, it drives the transmission screw 36 to rotate. Since the screw nut slider 33 is rolledly connected to the transmission screw 36 and slides along the inner wall of the transmission slide 31, it can drive the moving plate 34 to move synchronously. In addition, the drive motor 35 drives the cutting blade 38 to rotate. With the cutting groove 5 on the cutting table 1, the bottom end of the cutting blade 38 can be inserted into the groove to complete the cutting, avoiding cutting deviation and improving the flatness of the tarpaulin cut.

[0019] In this embodiment, an upper slide rail 13 is fixedly connected to the upper surface of the support cover 4, a limiting slider 8 is fixedly connected to the bottom surface of the support top plate 9, the inner wall of the limiting slider 8 is slidably connected to the outer surface of the upper slide rail 13, a limiting slide plate 12 is fixedly connected to the upper surface of the lower stretching flat plate 11, the outer surface of the limiting slide plate 12 is slidably connected to the inner wall of the support top plate 9, a bearing ring 62 is fixedly embedded on one side of the movable support plate 14, the inner ring of the bearing ring 62 is connected to the outer surface of one end of the drive wheel 63, two bearing rings 37 are fixedly installed on the inner wall of the transmission slide block 31, the inner rings of the two bearing rings 37 are fixedly connected to the outer surfaces of both ends of the transmission screw 36, and two feeding plates 15 are fixedly connected to one side of the cutting table 1. The upper surface of each plate 15 is provided with a feeding hole 17. The two feeding plates 15 are fixedly connected to a reinforcing rod 16 on their adjacent sides. Furthermore, the upper slide rail 13 on the support cover 4 and the limiting slider 8 can restrict the movement direction of the support top plate 9 and prevent it from deviating. Similarly, the limiting slide plate 12 on the lower stretching flat plate 11 ensures that the lower stretching flat plate 11 is raised and lowered smoothly, avoiding positional deviation when fixing the tarpaulin. The bearing ring 62 on the moving support plate 14 can assist the drive wheel 63 to rotate smoothly. The two bearing rings 37 in the transmission slide 31 can ensure the stable rotation of the transmission screw 36 and reduce component wear. The two feeding plates 15 and the feeding hole 17 are used to place the tarpaulin roll for easy feeding and unwinding.

[0020] The working process of this utility model is as follows: When using the camouflage tarpaulin stretching and cutting device, the operator first places the tarpaulin roll above the two feeding plates 15, using the feeding holes 17 on the feeding plates 15 for positioning. Then, one end of the tarpaulin roll is pulled above the lower stretching carrier plate 11, and the electric cylinder 10 is activated. The telescopic end of the electric cylinder 10 drives the lower stretching carrier plate 11 to rise, which can fix one end of the tarpaulin through the support top plate 9 and the lower stretching carrier plate 11. Subsequently, the servo motor 61 in the moving part 6 is activated, and the drive wheel 63 rolls on the lower slide rail 7, which can drive the moving support plate 14 and the upper support top plate 9 to move. During the movement, the support top plate 9 stretches and flattens the tarpaulin.

[0021] Once the tarpaulin is stretched to the specified length, the transmission cutting assembly 3 begins operation. The forward and reverse motors 32 start, driving the transmission screw 36 to rotate. The screw nut slider 33 slides along the inner wall of the transmission slide block 31, thereby moving the moving plate 34. Simultaneously, the drive motor 35 on the moving plate 34 drives the cutting blade 38 to rotate. The cutting blade 38 cuts the stretched tarpaulin below. After one cut is completed, the lower stretching carrier plate 11 is reset. The operator then places the new end of the tarpaulin roll on top of the lower stretching carrier plate 11 and repeats the above process of fixing, moving parts 6 stretching, and transmission cutting assembly 3 cutting, thus realizing continuous stretching and cutting of the camouflage tarpaulin. This is the working process and working principle of the device.
