Description

Technical Field

[0001] This utility model relates to the field of slitting device technology, and in particular to an easily adjustable slitting device for a coating machine. Background Technology

[0002] A coating machine is a mechanical device used to uniformly coat the surface of various substrates with adhesives, coatings or inks with specific functions. It is widely used in many industries. When using a coating machine, it is usually used in conjunction with a slitting device. The slitting device is mainly used to cut the coated materials (such as films, paper, etc.) according to the required size and specifications to meet the needs of subsequent processing or use.

[0003] When using a slitting device to slit materials on a coating machine, as the cutting blade passes through one side of the material and enters the other side to cut, the collision between the blade and the side of the material at the start of the cut can easily cause wrinkles on the surface of the material, resulting in deformation of the surface at the cutting position after the material is cut. Utility Model Content

[0004] The purpose of this invention is to solve the problem that when a cutting blade passes through one side of a material and enters the other side to cut, the blade collides with the side of the material at the beginning of the cutting, which easily causes wrinkles on the surface of the material and causes deformation of the surface at the cutting position after the material is cut. Therefore, this invention proposes an easily adjustable slitting device for coating machines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a slitting device for a coating machine that is easy to adjust, comprising:

[0006] The main body is placed on the ground to support the entire device;

[0007] The slitting assembly is installed on one side of the top of the machine body and is used to slit the material passing through the coating machine.

[0008] Clamping assembly, installed on the top of the machine body away from the slitting assembly, is used to pull the material passing through the coating machine to move and assist in slitting;

[0009] The positioning device is installed on the top of the machine body near the slitting component to position the surface of the material passing through the coating machine and prevent wrinkles from appearing on the surface during slitting.

[0010] Preferably, the slitting component includes:

[0011] A slotted plate is fixed to one side of the top of the machine body. The surface of the slotted plate has a through slot, and a lead screw and a drive motor for driving the lead screw to rotate are provided on the surface of the slotted plate.

[0012] The slide slides on one side of the top of the slot plate. The slide is located outside the lead screw at the top of the slot plate. The drive motor at the top of the slot plate controls the lead screw to rotate and move the slide. A cutting blade is provided on one side of the bottom of the slide.

[0013] The clamping assembly includes:

[0014] The slide slides at the top of the machine body. A lead screw and a drive motor for driving the lead screw to rotate are provided on the outer surface of the machine body. One end of the inner wall of the slide is located outside the lead screw at the top of the machine body. The operation of the drive motor can control the movement position of the slide on the outer surface of the lead screw and on one side of the machine body.

[0015] A support rod is fixed to one side of the slide to support the material.

[0016] The clamping rod moves up and down on one side of the slide to clamp the material. A hydraulic rod is provided on one side of the slide, and the clamping rod is installed on the output rod side of the hydraulic rod. The operation of the hydraulic rod to extend or retract can control the lifting and lowering of the clamping rod.

[0017] The effect achieved by the above components is as follows: When the slitting device is used to slit the material that has passed through the coating machine, the conveying mechanism on the coating machine transports the material to the through groove on the surface of the slot plate, allowing the material to pass through the through groove and protrude one end of the material inside the through groove. Then, the control panel on one side of the machine body controls the operation of the drive motor on the outside of the machine body. The drive motor drives the screw on one side of the slide to rotate, causing the slide to move towards the slot plate on the outside of the machine body. The pad on one side of the slide is positioned below the end of the material that protrudes from the through groove. Then, the hydraulic rod is operated to retract, controlling the clamping rod to descend and clamp the material on the surface of the material. The material is clamped by the clamping rod and the pad. Then, the drive motor on the outside of the machine body controls the slide to move away from the slot plate, pulling the material to the slitting length. Then, the drive motor at the top of the slot plate controls the screw to rotate, causing the slide to move away from the machine body on one side of the slot plate, driving the cutting blade into the surface of the material and moving it from one side of the material to the other side to cut the material. After cutting, the hydraulic rod is operated to extend, controlling the clamping rod to rise and remove the material.

[0018] Preferably, the positioning device includes:

[0019] The screw is installed on the inner wall of the machine body near the pad plate, and the two ends of the outer surface of the screw are provided with threads in opposite directions;

[0020] The servo motor is mounted on the outside of the machine body. The output end of the servo motor is connected to one end of the screw through a coupling. Operating the servo motor can control the rotation of the screw.

[0021] A slider, wherein a support rod is fixedly connected to one side of the bottom end of the slider, the inner wall of the support rod is threadedly connected to the outer surface of the screw, a pad is fixedly connected to one side of the slider, and an electric push rod is provided at the top of the slider;

[0022] The pressure block is mounted on one side of the slider via an electric push rod. The pressure block slides on one side of the slider. The operation of the electric push rod retracts to control the lifting and lowering of the pressure block on one side of the slider. A T-shaped groove is provided on one side of the slot plate. One end of the slider slides on the inner wall of the T-shaped groove. Grooves are provided on the surfaces of the pressure block and the pad block respectively.

[0023] The effect achieved by the above components is as follows: By setting up the pressure block, when using the cutting device, after the material passes through the through groove on the outer surface of the slot plate, the servo motor can be operated to drive the screw to rotate, so that one end of the two support rods moves in the same direction on the outer surface of the screw. The pads and pressure blocks on one side of the two sliders are controlled to be located on the upper and lower sides of the two sides of the material respectively. Then, the electric push rods at the top of the two sliders are operated to retract and control the pressure block to descend, pressing the bottom end of the pressure block onto the side surface of the material. The edge of the material is clamped by the pressure block and the pad. Then, the cutting blade cuts the material through the groove on the surface of the pressure block and the pad. By clamping the material with the pressure block and the pad, wrinkles at the edge of the material are avoided as much as possible during the cutting process.

[0024] Preferably, the bottom end of the pressure block and the top end of the pad block are respectively provided with a plurality of auxiliary strips, and the auxiliary strips are rubber strips made of rubber.

[0025] The effect achieved by the above components is that by setting the rubber auxiliary strip, the material is not prone to accidental slippage during the cutting process when it is pressed between the pressure block and the pad block.

[0026] Preferably, a positioning block is fixedly connected to one side of the pressure block, and one end of the positioning block slides on one side of the inner wall of the slider.

[0027] The effect achieved by the above components is that when the electric push rod controls the pressure block to move up and down, one end of the positioning block will slide on the inner wall of the slider. The positioning block can further limit the angle between the pressure block and the pad block, and avoid the angle of the pressure block from deviating as much as possible.

[0028] Preferably, an ejection device is provided on one side of the machine body. The ejection device includes a rotating shaft. A coil spring is provided at one end of the rotating shaft. The two ends of the coil spring are fixedly connected to one side of the rotating shaft and one side of the inner wall of the machine body, respectively. A push rod and a pressure plate are fixedly connected to the outer surface of the rotating shaft.

[0029] The effect achieved by the above components is as follows: after a section of material is cut off using the cutting device, the top of the pressure plate can be pressed to control the rotating shaft to rotate downwards, causing the push rod on the other side of the rotating shaft to move upwards and protrude into the machine body. The push rod lifts one edge of the material, making it easier for personnel to pick up and remove the material. After the pressure plate is released, the coil spring returns to its original state and drives the rotating shaft to rotate in the original direction, so that the pressure plate and push rod return to their original positions.

[0030] Preferably, a stop block is fixedly connected to the top of the pressure plate, and the stop block and the pressure plate form a certain angle.

[0031] The effect achieved by the above components is that when the pressure plate is pressed down to control the rotation of the shaft, the top of the stop block will contact one side of the inner wall of the machine body, thus limiting the rotation angle of the shaft.

[0032] Preferably, an auxiliary groove is provided on one side of the pressure plate, and the auxiliary groove is located on the top side of the pressure plate.

[0033] The effect achieved by the above components is that pressing the auxiliary groove at the top of the pressure plate makes it easier to control the pressure plate to rotate the shaft and prevents the hand from slipping.

[0034] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0035] In this invention, by setting a positioning device, after the material passes through the groove on the outer surface of the slot plate, the edge of the material is clamped by the pressure block and the pad block. Then, the cutting blade cuts the material by passing through the groove on the surface of the pressure block and the pad block. By clamping the material with the pressure block and the pad block, wrinkles at the edge of the material are avoided as much as possible during the cutting process, thus improving the practicality of the slitting device.

[0043] Example 1, as Figure 1-4As shown, an adjustable slitting device for a coating machine includes a body 1, which is placed on the ground to support the entire device. A slitting assembly 4 is installed on one side of the top of the body 1 for slitting the material passing through the coating machine. A clamping assembly 5 is installed on the top of the body 1 away from the slitting assembly 4 to pull the material passing through the coating machine and assist in slitting. A positioning device 2 is installed on the top of the body 1 near the slitting assembly 4 to position the surface of the material passing through the coating machine to avoid wrinkles during slitting. The slitting assembly 4 includes a groove plate 41, which is fixed to one side of the top of the body 1. A through groove 42 is formed on the surface of the groove plate 41, and a lead screw and a drive mechanism are provided on the surface of the groove plate 41. A drive motor drives the lead screw to rotate. A slide 43 slides on one side of the top of the slot plate 41. The slide 43 is located outside the lead screw at the top of the slot plate 41. The drive motor at the top of the slot plate 41 controls the rotation of the lead screw, causing the slide 43 to move. A cutting blade 44 is provided on one side of the bottom of the slide 43. The clamping assembly 5 includes a slide 51, which slides on the top of the machine body 1. A lead screw and a drive motor for driving the lead screw to rotate are provided on the outer surface of the machine body 1.

The drive motor can control the movement of the slide 51 on the outer surface of the lead screw and on one side of the machine body 1. A pad rod 52 is fixed to one side of the slide 51 to support the material. A clamping rod 54 is located on the slide 51. The slide 51 has a hydraulic rod 53 on one side, and a clamping rod 54 is installed on the output rod side of the hydraulic rod 53. Operating the hydraulic rod 53 to extend or retract controls the lifting and lowering of the clamping rod 54. When the slitting device slits the material passing through the coating machine, the conveying mechanism on the coating machine transports the material to the through groove 42 on the surface of the slot plate 41, allowing the material to pass through the through groove 42 and protrude one end from the inside of the through groove 42. Then, the control panel on one side of the machine body 1 controls the operation of the drive motor on the outside of the machine body 1. The drive motor drives the screw on one side of the slide 51 to rotate, causing the slide 51 to move towards the slot plate 41 from the outer surface of the machine body 1. The control rod 52 on one side of the slide 51 is also controlled. Located below one end of the material protruding through the groove 42, the hydraulic rod 53 is then operated to retract and control the clamping rod 54 to descend, clamping the material surface with the clamping rod 54 and the pad rod 52 to hold the material. Then, the drive motor on the outside of the machine body 1 controls the slide 51 to move away from the groove plate 41, pulling the material to the cutting length. Then, the drive motor at the top of the groove plate 41 controls the screw to rotate, causing the slide 43 to move away from the machine body 1 on one side of the groove plate 41, driving the cutting blade 44 into the surface of the material and moving from one side of the material to the other side to cut the material. After cutting, the hydraulic rod 53 is operated to extend and control the clamping rod 54 to rise, and the material can be taken out.

[0044] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4and Figure 6 As shown in this embodiment: the positioning device 2 includes a screw 22, which is installed on the inner wall of the machine body 1 near the pad. The outer surface of the screw 22 has threads in opposite directions at both ends. A servo motor 21 is installed on the outer side of the machine body 1. The output end of the servo motor 21 is connected to one end of the screw 22 via a coupling. Operating the servo motor 21 can control the rotation of the screw 22. A support rod 26 is fixedly connected to one side of the bottom end of the slider 24. The inner wall of the support rod 26 is threadedly connected to the outer surface of the screw 22. A pad 25 is fixedly connected to one side of the slider 24. An electric push rod 27 is provided at the top of the slider 24. A pressure block 28 is installed on one side of the slider 24 via the electric push rod 27. The pressure block 28 slides on one side of the slider 24. Operating the electric push rod 27 to retract can control the lifting and lowering of the pressure block 28 on one side of the slider 24. A T-shaped groove 23 is provided on one side of the slot plate 41. One end of the slider 24 is in the T-shaped groove 23. The inner wall of the 3 slides, and the surfaces of the pressure block 28 and the pad block 25 are respectively provided with grooves. By setting the pressure block 28, when using the cutting device, after the material passes through the through groove 42 on the outer surface of the groove plate 41, the servo motor 21 can be operated to drive the screw 22 to rotate, so that one end of the two support rods 26 moves in the same direction on the outer surface of the screw 22. The pad block 25 and the pressure block 28 on one side of the two sliders 24 are respectively located on the upper and lower sides of the two sides of the material. Then, the electric push rod 27 at the top of the two sliders 24 is operated to retract and control the pressure block 28 to descend, pressing the bottom end of the pressure block 28 onto the side surface of the material. The edge of the material is clamped by the pressure block 28 and the pad block 25. Then, the cutting blade 44 cuts the material through the groove on the surface of the pressure block 28 and the pad block 25. The pressure block 28 and the pad block 25 clamp the material to avoid wrinkles at the edge of the material during the cutting process.

[0045] Reference Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown in this embodiment: several auxiliary strips 29 are respectively provided at the bottom of the pressure block 28 and the top of the pad block 25. The auxiliary strips 29 are rubber strips. By setting the rubber auxiliary strips 29, the material is not easy to slip accidentally when being cut while being pressed between the pressure block 28 and the pad block 25.

[0046] Reference Figure 2 , Figure 3 , Figure 4 and Figure 6As shown in this embodiment: a positioning block 210 is fixedly connected to one side of the pressure block 28. One end of the positioning block 210 slides on one side of the inner wall of the slider 24. When the electric push rod 27 controls the pressure block 28 to move up and down, one end of the positioning block 210 will slide on the inner wall of the slider 24. The positioning block 210 can further limit the angle between the pressure block 28 and the pad block 25, and avoid the angle of the pressure block 28 from deviating as much as possible.

[0047] Reference Figure 1-5 As shown in this embodiment: A push-out device 3 is provided on one side of the machine body 1. The push-out device 3 includes a rotating shaft 31. A coil spring 32 is provided at one end of the rotating shaft 31. The two ends of the coil spring 32 are fixedly connected to one side of the rotating shaft 31 and one side of the inner wall of the machine body 1, respectively. A push rod 33 and a pressure plate 34 are fixedly connected to the outer surface of the rotating shaft 31. After a section of material is cut off using the cutting device, the top of the pressure plate 34 can be pressed to control the rotating shaft 31 to rotate downward, so that the push rod 33 on the other side of the rotating shaft 31 moves upward and protrudes into the machine body 1. The push rod 33 lifts up one edge of the material, making it easy for personnel to pick up and remove the material. After the pressure plate 34 is released, the coil spring 32 returns to its original state and drives the rotating shaft 31 to rotate in the original direction, so that the pressure plate 34 and the push rod 33 return to their original positions.

[0048] Reference Figure 2-5 As shown in this embodiment: a stop block 35 is fixedly connected to the top of the pressure plate 34. The stop block 35 and the pressure plate 34 form a certain angle. When the pressure plate 34 is pressed down to control the rotation of the shaft 31, the top of the stop block 35 will contact one side of the inner wall of the machine body 1, thus limiting the rotation angle of the shaft 31. An auxiliary groove 36 is provided on one side of the pressure plate 34. The auxiliary groove 36 is located on one side of the top of the pressure plate 34. Pressing the auxiliary groove 36 at the top of the pressure plate 34 can more conveniently control the pressure plate 34 to rotate the shaft 31 and prevent the hand from slipping.

[0049] Working Principle: When the slitting device slits the material after it has passed through the coating machine, the conveying mechanism on the coating machine transports the material to the through groove 42 on the surface of the groove plate 41. The material passes through the through groove 42, with one end protruding from the inside of the through groove 42. The control panel on one side of the machine body 1 controls the operation of the drive motor on the outside of the machine body 1. The drive motor drives the screw on one side of the slide 51 to rotate, causing the slide 51 to move from the outer surface of the machine body 1 towards the groove plate 41. The pad rod 52 on one side of the slide 51 is positioned below the end of the material protruding from the through groove 42. Then, the hydraulic rod 53 retracts, controlling the clamping rod 54 to descend. The clamping rod 54 clamps the material surface, and the material is held by the clamping rod 54 and the pad rod 52. The drive motor on the outside of the machine body 1 then controls the slide 51 to move away from the groove plate 41, pulling the material to the slitting length. Finally, the servo motor 21 drives the screw 22 to rotate, causing one end of each of the two support rods 26 to be respectively positioned on the screw. The outer surface of rod 22 moves in the same opposite direction, controlling the pads 25 and pressure blocks 28 on one side of the two sliders 24 to be located on the upper and lower sides of the material's two edges respectively. Then, the electric push rods 27 at the top of the two sliders 24 are operated to retract and control the pressure blocks 28 to descend, pressing the bottom of the pressure blocks 28 onto the side surface of the material. The edges of the material are clamped by the pressure blocks 28 and pads 25. Then, the drive motor at the top of the slot plate 41 controls the screw to rotate, causing the slide 43 to move away from the machine body 1 on one side of the slot plate 41, driving the cutting blade 44 into the surface of the material and moving from one side of the material to the other side to cut the material. After cutting, the hydraulic rod 53 is operated to extend and control the clamping rod 54 to rise. The top of the pressure plate 34 is pressed to control the rotating shaft 31 to rotate downward, causing the top rod 33 on the other side of the rotating shaft 31 to move upward and protrude into the machine body 1. The top rod 33 lifts one edge of the material and removes the material.
