[0002] In the processing and production of wooden floors, plastic floors and other wooden materials, the boards will be packaged with films to varying degrees. Generally, wear-resistant film paper is affixed on both sides of the boards to enhance the wear resistance of the board surface. Compared with solid wood sawn timber, the wood surface after film packaging has excellent properties such as wear resistance, heat resistance, water resistance, chemical pollution resistance, smoothness, and easy cleaning. In addition, it has low raw material requirements, a wide range of sources, high wood utilization rate, multiple product specifications, and good processing performance. It has been widely used in furniture manufacturing, facade decoration inside vehicles and ships, interior decoration and other fields.

[0003] Among them, when coating wood, a film bag is often put on the outer wall of the board, and then the board and the film bag are sent to a heat shrink machine so that the film bag is completely attached to the outer wall of the board. This method has a low efficiency in coating the board. In view of the above problems, the following solutions are proposed. Summary of the invention

[0005] The feeding mechanism includes a support frame fixedly connected to the top of the base, a cylinder 1 is rotatably connected to the inner wall of the support frame, a cylinder 2 is rotatably connected to the inner wall of the support frame, a clamp is fixedly connected to the top of the base, a fixed bracket is fixedly connected to the top of the support frame, a collecting column is rotatably connected to the inner wall of the fixed bracket, a covering film is sleeved on the outer wall of the collecting column, and a pulling component is fixedly connected to the inner wall of the collecting column;

[0006] The power mechanism comprises an electric telescopic frame fixedly connected to the top of the base, a cutter is fixedly connected to the bottom of the electric telescopic frame, two sliding plates are slidably connected to the side wall of the cutter, a slide groove is provided on the side wall of the cutter, a spring telescopic rod is fixedly connected to the inner wall of the slide groove, an arc-shaped blocking block is fixedly connected to the other end of the spring telescopic rod, a plurality of limit grooves are provided on the side wall of the sliding plate, a hot melter is fixedly connected to the bottom of the two sliding plates, and a smoothing component is fixedly connected to the top of the cutter. Before use, the base is installed in the desired position, and then one end of the covering film is pulled downward to ensure that one end of the covering film is fixed inside the clamp, and then the power of the motor is turned on to ensure that the wooden board passes through the gap between the second cylinder and the first cylinder, and finally falls on the top of the conveyor belt, presenting as shown in the figure.Figure 5 The cutter will slide downward along the inner wall of the sliding plate and divide the two hot-melt marks, forming a layer of film on the outer wall of the wooden board. Subsequently, the motor drives the conveyor belt to transmit through the rolling column, so that the coated wooden board enters the interior of the heat shrink machine, completing the process of coating the wooden board. Through the application of the above components, the process of rapid film covering and coating of the equipment can be realized, thereby improving the working efficiency of the equipment.

[0007] Preferably, the pulling assembly includes a rotating ring fixedly connected to the inner wall of the collecting column, a limiting groove is opened on the side wall of the rotating ring, and a support column is fixedly connected to the side wall of the fixed bracket. When the wooden board is covered with the above-mentioned covering film, the collecting column will produce the characteristic of rotation. A pulling assembly is arranged inside the equipment. When the wood enters the gap between cylinder one and cylinder two, the covering film will drive the collecting column to rotate, and the rotating collecting column drives the rotating ring to rotate synchronously. In this process, since the support column is in a stationary state, during the rotation of the rotating ring, turbine spring one will deform and accumulate mechanical power.

[0008] Preferably, the pulling assembly also includes a turbine spring 1 fixedly connected to the side wall of the support column, the end of the turbine spring 1 away from the support column is fixedly connected to a fixing frame 1, and the inner wall of the fixing frame 1 is slidably connected to an arc-shaped slider 1. If the length of the wooden board is too long, the number of rotations of the rotating ring will exceed the bearing capacity of the turbine spring 1. At this time, the turbine spring 1 will drive the arc-shaped slider 1 to slide along the inner wall of the fixing frame 1, and cause the arc-shaped slider 1 to slide.

[0009] Preferably, the pulling assembly further comprises a spring 1 fixedly connected to one side wall of the arc-shaped slider, one end of the spring 1 away from the arc-shaped slider 1 is fixedly connected to the inner wall of the fixing frame 1, the outer wall of the supporting column is rotatably connected to the inner wall of the through hole of the collecting column, and after the covering film is cut, the covering film will appear as follows: Figure 8 state, at this time, the turbine spring releases mechanical power, forcing the turbine spring to drive the rotating ring and the collecting column to rotate in the opposite direction through the arc-shaped slider, and the collecting column rotating in the opposite direction will collect the remaining covering film. Through the application of the above components, after each cutting of the covering film is completed, the excess covering film will always be in a taut state under the collection of the collecting column.

[0010] Preferably, the smoothing assembly includes a second fixing frame fixedly connected to the top of the cutter, one end of the second fixing frame away from the cutter is fixedly connected to a second spring telescopic rod, and one end of the second spring telescopic rod away from the second fixing frame is fixedly connected to a mounting rod.

[0011] Preferably, the smoothing assembly also includes a supporting square rod fixedly connected to the top of the heat shrink machine, four gear rods are fixedly connected to the bottom of the supporting square rod, and four mounting grooves are opened on the top of the mounting rod.

[0012] Preferably, the smoothing component also includes a rotating column rotatably connected to the inner wall of the mounting groove, a contact wheel is fixedly connected to the side wall of the rotating column, and a mounting ring is fixedly connected to the end of the rotating column away from the contact wheel. The electric telescopic frame is used to drive the cutter to move downward, and a smoothing component is arranged inside the equipment. When the cutter moves downward, the cutter drives the mounting rod to move downward through the second fixed frame and the second spring telescopic rod, and at this time the downward-moving mounting rod will drive the rotating column and the mounting ring to move downward synchronously, and the mounting ring drives the outer wall of the rotating square plate to contact the inner wall of the gear rod, presenting a Figure 10 At this time, the rotating square plate is blocked, driving the mounting ring to rotate clockwise around the rotating column, and the rotating mounting ring will drive the turbine spring 2 to deform and accumulate mechanical power.

[0013] Preferably, the smoothing component also includes a bevel groove provided at the side wall of the mounting ring, a rotating square plate is rotatably connected to the inner wall of the bevel groove, a fixed cylinder is fixedly connected to the inner wall of the mounting groove, and a turbine spring 2 is fixedly connected to the side wall of the fixed cylinder, and the end of the turbine spring 2 away from the fixed cylinder is fixedly connected to the inner wall of the mounting ring. As the electric telescopic frame continues to shrink, the gear rod will no longer contact the rotating square plate due to insufficient length of the gear rod. At this time, the mounting ring loses restriction, and the turbine spring 2 will release mechanical power, causing the mounting ring, the rotating column and the contact wheel to rotate counterclockwise, and multiple counterclockwise rotating contact wheels contact the top of the covering film during the downward movement, pulling the covering film on the top of the wooden board. Through the application of the above-mentioned components, it is ensured that the covering film is tightly attached to the outer wall of the wooden board during hot melting. Through the application of the above-mentioned components, it is ensured that the covering film on the outer wall of the wooden board is flat when the wooden board enters the hot melting, thereby improving the film coating effect of the equipment.

[0014] The present invention has the following beneficial effects:

[0015] (1) The present invention aims to solve the problem that the process of bagging wooden boards is troublesome. A feeding mechanism and a power mechanism are arranged inside the equipment. Before use, the base is installed at the desired position, and then one end of the covering film is pulled downward and one end of the covering film is fixed inside the clamp. Then the power of the motor is turned on and the wooden board is ensured to pass through the gap between the second cylinder and the first cylinder and finally fall on the top of the conveyor belt, presenting a Figure 5The cutter will slide downward along the inner wall of the sliding plate and divide the two hot-melt marks, forming a layer of film on the outer wall of the wooden board. Subsequently, the motor drives the conveyor belt to transmit through the rolling column, so that the coated wooden board enters the interior of the heat shrink machine, completing the process of coating the wooden board. Through the application of the above components, the process of rapid film covering and coating of the equipment can be realized, thereby improving the working efficiency of the equipment.

[0016] (2) The present invention utilizes the characteristic that the electric telescopic frame drives the cutter to move downward, and a smoothing component is arranged inside the device. When the cutter moves downward, the cutter drives the mounting rod to move downward through the second fixed frame and the second spring telescopic rod. At this time, the downwardly moving mounting rod drives the rotating column and the mounting ring to move downward synchronously, and the mounting ring drives the outer wall of the rotating square plate to contact the inner wall of the gear rod, presenting the following Figure 10 The rotating square plate is in a state of one, and at this time the rotating square plate is blocked, driving the mounting ring to rotate clockwise around the rotating column, and the rotating mounting ring will drive the turbine spring 2 to deform and accumulate mechanical power; as the electric telescopic frame continues to shrink, the gear rod will no longer contact the rotating square plate due to insufficient length of the gear rod. At this time, the mounting ring loses its restriction, and the turbine spring 2 will release mechanical power, causing the mounting ring, the rotating column and the contact wheel to rotate counterclockwise, and multiple counterclockwise rotating contact wheels contact the top of the covering film during the downward movement, pulling the covering film on the top of the wooden board. Through the application of the above-mentioned components, it is ensured that the covering film is tightly attached to the outer wall of the wooden board during hot melting. Through the application of the above-mentioned components, it is ensured that the outer wall covering film of the wooden board is flat when the wooden board enters the hot melting, thereby improving the film coating effect of the equipment.

[0017] (3) The present invention utilizes the characteristic that the gear rod drives the mounting ring to rotate by rotating the square plate, and a bevel groove is provided inside the equipment. After the contact wheel completes the smoothing process, the electric telescopic frame generates an extension force to drive the multiple components to reset. During this process, the mounting rod drives the mounting ring to move upward synchronously, so that the outer wall of the rotating square plate contacts the bottom of the gear rod. While the two are in contact, the rotating square plate will swing around the connection point. At this time, the gear rod will not be able to drive the mounting ring to rotate by rotating the square plate. Through the application of the above-mentioned components, when the components are reset, the turbine spring 2 will not accumulate mechanical power, thereby avoiding the change in the direction of the contact wheel when the water flow is working.

[0018] (4) The present invention utilizes the characteristic that when the above-mentioned covering film covers the wooden board, the collecting column will rotate. A pulling component is arranged inside the equipment. When the wood enters the gap between cylinder 1 and cylinder 2, the covering film will drive the collecting column to rotate, and the rotating collecting column drives the rotating ring to rotate synchronously. In this process, since the supporting column is in a stationary state, the turbine spring 1 will deform and accumulate mechanical power during the rotation of the rotating ring. If the length of the wooden board is too long, the number of rotations of the rotating ring will exceed the bearing capacity of the turbine spring 1, and at this time, the turbine spring 1 will drive the arc-shaped slider 1 to slide along the inner wall of the fixed frame 1, and cause the arc-shaped slider 1 to slide. After the covering film is cut, the covering film will appear as follows. Figure 8 state, at this time, the turbine spring releases mechanical power, forcing the turbine spring to drive the rotating ring and the collecting column to rotate in the opposite direction through the arc-shaped slider, and the collecting column rotating in the opposite direction will collect the remaining covering film. Through the application of the above components, after each cutting of the covering film is completed, the excess covering film will always be in a taut state under the collection of the collecting column.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] For example, see Figure 1 - Figure 7 The present invention is an auxiliary film coating device for wood packaging, comprising a base 1, a heat shrink machine 11 is fixedly connected to the top of the base 1, a bracket 12 is fixedly connected to the top of the base 1, two rolling columns 13 are rotatably connected to the inner wall of the bracket 12, a conveyor belt 14 is sleeved on the outer wall of the two rolling columns 13, and a motor 15 is fixedly connected to the top of the base 1;

[0035] The feeding mechanism 2 includes a support frame 21 fixedly connected to the top of the base 1, a cylinder 1 22 is rotatably connected to the inner wall of the support frame 21, a cylinder 23 is rotatably connected to the inner wall of the support frame 21, a clamp 24 is fixedly connected to the top of the base 1, a fixed bracket 27 is fixedly connected to the top of the support frame 21, a collecting column 25 is rotatably connected to the inner wall of the fixed bracket 27, a covering film 26 is sleeved on the outer wall of the collecting column 25, and a pulling component 4 is fixedly connected to the inner wall of the collecting column 25;

[0036] The power mechanism 3 includes an electric telescopic frame 31 fixedly connected to the top of the base 1, a cutter 32 is fixedly connected to the bottom of the electric telescopic frame 31, two sliding plates 36 are slidably connected to the side wall of the cutter 32, a slide groove 33 is provided on the side wall of the cutter 32, a spring telescopic rod 34 is fixedly connected to the inner wall of the slide groove 33, an arc-shaped blocking block 35 is fixedly connected to the other end of the spring telescopic rod 34, a plurality of limiting grooves 37 are provided on the side wall of the sliding plate 36, a hot melter 38 is fixedly connected to the bottom of the two sliding plates 36, and a smoothing component 5 is fixedly connected to the top of the cutter 32. Before use, the base 1 is installed in the desired position, and then one end of the covering film 26 is pulled downward to ensure that one end of the covering film 26 is fixed inside the clamp 24, and then the power of the motor 15 is turned on to ensure that the wooden board passes through the gap between the cylinder 23 and the cylinder 1 22 and finally falls on the top of the conveyor belt 14, presenting as shown in the figure. Figure 5 The cover film 26 is in the middle G state, and at this time the cover film 26 will completely cover the upper and lower parts of the wooden board. Then the electric telescopic frame 31 drives the cutter 32 to move downward, and the cutter 32 that moves downward drives the sliding plate 36 to move downward synchronously through the arc-shaped blocking block 35, so that the hot melters 38 move downward synchronously. The two hot melters 38 that move downward will make two hot melt marks on the outer wall of the cover film 26. As the electric telescopic frame 31 continues to move downward, the force of the cutter 32 moving downward will force the arc-shaped blocking block 35 to expand and contract along the inner wall of the slide groove 1 33 toward the spring. The rod 34 moves horizontally in the direction so that the arc-shaped blocking block 35 no longer restricts the cutter 32. The cutter 32 will slide downward along the inner wall of the sliding plate 36 and divide the two hot melt marks, so that a layer of film is formed on the outer wall of the wooden board. Subsequently, the motor 15 drives the conveyor belt 14 to transmit through the rolling column 13, so that the coated wooden board enters the heat shrink machine 11, completing the process of coating the wooden board. Through the application of the above components, the equipment can realize the rapid film covering and coating processes, thereby improving the working efficiency of the equipment.

[0037] For example 2, please refer to Figure 8 - Fig.11The present invention is an auxiliary film covering device for wood packaging. On the basis of the first embodiment, the pulling component 4 includes a rotating ring 41 fixedly connected to the inner wall of the collecting column 25, a limiting groove 42 is opened at the side wall of the rotating ring 41, and a supporting column 43 is fixedly connected to the side wall of the fixed bracket 27. When the wooden board is covered with the above-mentioned covering film 26, the collecting column 25 will produce the characteristic of rotation. The pulling component 4 is arranged inside the device. When the wood enters the gap between the cylinder 1 22 and the cylinder 2 23, the covering film 26 will drive the collecting column 25 to rotate, and the rotating collecting column 25 drives the rotating ring 41 to rotate synchronously. In this process, since the supporting column 43 is in a stationary state, during the rotation of the rotating ring 41, the turbine spring 1 44 will be deformed and accumulate mechanical power.

[0038] The pulling assembly 4 also includes a turbine spring 44 fixedly connected to the side wall of the support column 43, and one end of the turbine spring 44 away from the support column 43 is fixedly connected to a fixing frame 45, and an arc-shaped slider 46 is slidably connected to the inner wall of the fixing frame 45. If the length of the wooden board is too long, the number of rotations of the rotating ring 41 exceeds the bearing capacity of the turbine spring 44, and at this time, the turbine spring 44 will drive the arc-shaped slider 46 to slide along the inner wall of the fixing frame 45, and cause the arc-shaped slider 46 to slide.

[0039] The pulling assembly 4 also includes a spring 47 fixedly connected to the side wall of the arc-shaped slider 46. The end of the spring 47 away from the arc-shaped slider 46 is fixedly connected to the inner wall of the fixing frame 45. The outer wall of the support column 43 is rotatably connected to the inner wall of the through hole of the collecting column 25. After the covering film 26 is cut, the covering film 26 will appear as follows. Figure 8 state, at this time, the turbine spring 44 releases mechanical power, forcing the turbine spring 44 to drive the rotating ring 41 and the collecting column 25 to rotate in the opposite direction through the arc-shaped slider 46, and the collecting column 25 rotating in the opposite direction will collect the remaining covering film 26. Through the application of the above-mentioned components, after each cutting of the covering film 26 is completed, the excess covering film 26 will always be in a taut state under the collection of the collecting column 25.

[0040] The smoothing assembly 5 includes a second fixing frame 51 fixedly connected to the top of the cutter 32 , an end of the second fixing frame 51 away from the cutter 32 is fixedly connected to a second spring telescopic rod 52 , and an end of the second spring telescopic rod 52 away from the second fixing frame 51 is fixedly connected to a mounting rod 53 .

[0041] The smoothing assembly 5 also includes a supporting square rod 54 fixedly connected to the top of the heat shrink machine 11 , four gear rods 55 are fixedly connected to the bottom of the supporting square rod 54 , and four mounting grooves 56 are formed on the top of the mounting rod 53 .

[0042] The smoothing component 5 also includes a rotating column 57 rotatably connected to the inner wall of the mounting groove 56, a contact wheel 58 is fixedly connected to the side wall of the rotating column 57, and a mounting ring 59 is fixedly connected to the end of the rotating column 57 away from the contact wheel 58. The electric telescopic frame 31 drives the cutter 32 to move downward, and a smoothing component 5 is arranged inside the device. When the cutter 32 moves downward, the cutter 32 drives the mounting rod 53 to move downward through the fixed frame 2 51 and the spring telescopic rod 2 52. At this time, the downwardly moving mounting rod 53 will drive the rotating column 57 and the mounting ring 59 to move downward synchronously, and the mounting ring 59 drives the outer wall of the rotating square plate 511 to contact the inner wall of the gear rod 55, presenting a Figure 10 At this time, the rotating square plate 511 is blocked and drives the mounting ring 59 to rotate clockwise around the rotating column 57. The rotating mounting ring 59 drives the turbine spring 2 513 to deform and accumulate mechanical power.

[0043] The smoothing component 5 also includes a bevel groove 510 provided on the side wall of the mounting ring 59, a rotating square plate 511 is rotatably connected to the inner wall of the bevel groove 510, a fixed cylinder 512 is fixedly connected to the inner wall of the mounting groove 56, a turbine spring 2 513 is fixedly connected to the side wall of the fixed cylinder 512, and one end of the turbine spring 2 513 away from the fixed cylinder 512 is fixedly connected to the inner wall of the mounting ring 59. As the electric telescopic frame 31 continues to shrink, the gear rod 55 will no longer contact the rotating square plate 511 due to the insufficient length of the gear rod 55. At this time, the mounting ring 59 loses its restriction, and the turbine spring 2 513 will release mechanical power, causing the mounting ring 59, the rotating column 57 and the contact wheel 58 to rotate counterclockwise, and the multiple counterclockwise rotating contact wheels 58 will contact the top of the covering film 26 during the downward movement, pulling the covering film 26 on the top of the wooden board. Through the application of the above components, it is ensured that the covering film 26 is tightly attached to the outer wall of the wooden board during hot melting. Through the application of the above components, it is ensured that the covering film 26 on the outer wall of the wooden board is flat when the wooden board enters the hot melting, thereby improving the coating effect of the equipment.

[0044] A specific application of this embodiment is: before use, the base 1 is installed at the desired position, then one end of the covering film 26 is pulled downward, and one end of the covering film 26 is ensured to be fixed inside the clamp 24, then the power of the motor 15 is turned on, and the wooden board is ensured to pass through the gap between the second cylinder 23 and the first cylinder 22, and finally falls on the top of the conveyor belt 14, presenting as shown in FIG. Figure 5The cover film 26 is in the middle G state, and at this time the cover film 26 will completely cover the upper and lower parts of the wooden board. Then the electric telescopic frame 31 drives the cutter 32 to move downward, and the cutter 32 that moves downward drives the sliding plate 36 to move downward synchronously through the arc-shaped blocking block 35, so that the hot melters 38 move downward synchronously. The two hot melters 38 that move downward will make two hot melt marks on the outer wall of the cover film 26. As the electric telescopic frame 31 continues to move downward, the force of the cutter 32 moving downward will force the arc-shaped blocking block 35 to expand and contract along the inner wall of the slide groove 1 33 toward the spring. The rod 34 moves horizontally in the direction so that the arc-shaped blocking block 35 no longer restricts the cutter 32. The cutter 32 will slide downward along the inner wall of the sliding plate 36 and divide the two hot melt marks, so that a layer of film is formed on the outer wall of the wooden board. Subsequently, the motor 15 drives the conveyor belt 14 to transmit through the rolling column 13, so that the coated wooden board enters the heat shrink machine 11, completing the process of coating the wooden board. Through the application of the above components, the equipment can realize the rapid film covering and coating processes, thereby improving the working efficiency of the equipment.

[0045] By utilizing the characteristic that the electric telescopic frame 31 drives the cutter 32 to move downward, a smoothing component 5 is arranged inside the device. When the cutter 32 moves downward, the cutter 32 drives the mounting rod 53 to move downward through the fixing frame 2 51 and the spring telescopic rod 2 52. At this time, the downwardly moving mounting rod 53 drives the rotating column 57 and the mounting ring 59 to move downward synchronously. The mounting ring 59 drives the outer wall of the rotating square plate 511 to contact the inner wall of the gear rod 55, presenting a Figure 10 The rotating square plate 511 is in a state of one, and at this time the rotating square plate 511 is blocked and drives the mounting ring 59 to rotate clockwise around the rotating column 57, and the rotating mounting ring 59 will drive the turbine spring 2 513 to deform and accumulate mechanical power; as the electric telescopic frame 31 continues to shrink, the gear rod 55 will no longer contact the rotating square plate 511 due to the insufficient length of the gear rod 55. At this time, the mounting ring 59 loses its restriction, and the turbine spring 2 513 will release the mechanical power, causing the mounting ring 59, the rotating column 57 and the contact wheel 58 to rotate counterclockwise, and multiple counterclockwise rotating contact wheels 58 contact the top of the covering film 26 during the downward movement, pulling the covering film 26 on the top of the wooden board. Through the application of the above-mentioned components, it is ensured that the covering film 26 is tightly attached to the outer wall of the wooden board during hot melting. Through the application of the above-mentioned components, it is ensured that the wooden board is flat on the outer wall of the wooden board when entering the hot melting, thereby improving the film coating effect of the equipment.

[0046] Taking advantage of the characteristic that the gear rod 55 drives the mounting ring 59 to rotate by rotating the square plate 511, a bevel groove 510 is provided inside the equipment. After the contact wheel 58 completes the smoothing process, the electric telescopic frame 31 generates an extension force to drive multiple components to reset. During this process, the mounting rod 53 drives the mounting ring 59 to move upward synchronously, so that the outer wall of the rotating square plate 511 contacts the bottom of the gear rod 55. While the two are in contact, the rotating square plate 511 will swing around the connection point. At this time, the gear rod 55 will not be able to drive the mounting ring 59 to rotate by rotating the square plate 511. Through the application of the above-mentioned components, when the components are reset, the turbine spring 2 513 will not accumulate mechanical power, thereby avoiding the change in the direction of the contact wheel 58 when the water flow is working.

[0047] When the wooden board is covered with the covering film 26, the collecting column 25 will rotate. A pulling component 4 is arranged inside the device. When the wood enters the gap between the cylinder 1 22 and the cylinder 2 23, the covering film 26 will drive the collecting column 25 to rotate, and the rotating collecting column 25 drives the rotating ring 41 to rotate synchronously. In this process, since the supporting column 43 is in a stationary state, the turbine spring 1 44 will deform and accumulate mechanical power during the rotation of the rotating ring 41. If the length of the wooden board is too long, the number of rotations of the rotating ring 41 exceeds the bearing capacity of the turbine spring 1 44, and at this time the turbine spring 1 44 will drive the arc-shaped slider 1 46 to slide along the inner wall of the fixing frame 1 45, and cause the arc-shaped slider 1 46 to slide. After the covering film 26 is cut, the covering film 26 will appear as follows. Figure 8 state, at this time, the turbine spring 44 releases mechanical power, forcing the turbine spring 44 to drive the rotating ring 41 and the collecting column 25 to rotate in the opposite direction through the arc-shaped slider 46, and the collecting column 25 rotating in the opposite direction will collect the remaining covering film 26. Through the application of the above-mentioned components, after each cutting of the covering film 26 is completed, the excess covering film 26 will always be in a taut state under the collection of the collecting column 25.
