Description

Technical Field

[0001] The utility model relates to the technical field of release paper cutting, in particular to a release paper processing and cutting device. Background Art

[0002] Release paper is a specially treated paper product. By coating one or more layers of anti-stick material (such as silicone oil) on the paper surface, the paper has anti-stick and isolation functions. It is mainly used to protect sticky substances and prevent them from adhering to other objects during storage, transportation or processing. Release paper is widely used, mainly including carriers of tapes or adhesive products. It is often used in food packaging and medical and health industries. Release paper is also used in the medical and health fields, such as isolation of surgical dressings. During use, it usually needs to be cut to a suitable size according to usage requirements.

[0003] The document with publication number CN212146555U discloses a cutting device for processing coated release paper, including a box body, a paper roll seat and a tightening frame. The inner bottom wall of the box body is fixedly connected to the bottom of the paper roll seat, and the bottom of the tightening frame is fixedly connected to the inner bottom wall of the box body. The transmission pressure roller is driven by a motor to rotate, and the release paper is driven to the punching cutter for punching and cutting. The processed release paper can be taken out by pulling the lower hopper.

[0004] The advantage of the above scheme is that the cutting of the release paper is driven by a motor, which has continuous cutting, improves the cutting efficiency, and is easy to collect. However, this technical scheme still has some shortcomings. In the above scheme, the movement of the release paper is driven by the motor to drive the transmission pressure roller to move to the right, and the cutting is completed by the punching cutter. The cut release paper falls into the unloading bin under the action of the accumulation. If subsequent processing is required, the cut release paper can only be moved to the next process through manual operation. When faced with the required irregular-shaped release paper, the release paper is likely to touch the punching cutter due to the accumulation of accumulation during the stacking process, resulting in defective products. The processing materials in the above scheme are manually transferred, which can be changed to mechanical material collection in the prior art. The material collection method using a suction cup has excellent effect but a more complicated structure. If a lever structure is used to collect materials, there may be a problem of vacant positions, which may cause the material to be unable to be completely collected. Utility Model Content

[0005] In view of the technical defects existing in the background technology, the utility model proposes a release paper processing and cutting device, which solves the technical problem that the cut release paper cannot be automatically transported to the next process, and when facing irregular release paper products, the accumulation of the release paper touches the punching cutter, resulting in defective products, and meets the actual needs. The specific technical solution is as follows:

[0006] A release paper processing and cutting device comprises a box body, an air press, a conveyor belt, a pressure feeding arm, a connecting rod, a cutting mechanism and a workbench, wherein the box body is provided with a feed port and a discharge port at the head and end along the material travel direction, the conveyor belt is arranged at the top of the box body and connected with the pressure feeding arm, the air press is connected to the top of the box body through a connecting block, the workbench is arranged at the bottom of the box body opposite to the output direction of the air press, the pressure feeding arm is divided into a connecting plate, a telescopic arm and a mechanical claw and are sequentially connected by transmission from top to bottom, a threaded hole is arranged at the center of the connecting plate, the connecting plate is connected to the conveyor belt by a connecting rod and the threaded hole, the air press is provided with an active groove for the pressure feeding arm to reciprocate under the drive of the transmission belt, and a damping member is arranged at the bottom of the mechanical claw for contacting the material; the cutting mechanism consists of a first cutting roller and a second cutting roller, wherein the first cutting roller and the second cutting roller are arranged side by side and tangent to each other, and are symmetrically arranged at the upper and lower positions of the working plane with the working plane of the workbench as a reference.

[0007] After adopting the above technical scheme, the utility model has the following advantages: the required processed products are fed into the box body, and the required processed products are fixed on the workbench and transported to the cutting roller through the mechanical claws on the pressing arm in the box body, and the pressing arm is connected to the conveyor belt through a connecting rod, and the pressing speed of the pressing arm is the same as the running speed of the conveyor belt, and is also the same as the cutting speed of the release paper. When the pressing arm completes the pressing, it also represents the completion of the cutting process. If the cutting process is not completed at this time, the conveyor belt can be returned to the entrance of the box to continue pressing until the cutting process is completed and the cut release paper is transported to the next process, thereby solving the problem of product fixing. The air press in the pressing mechanism generates air pressure, and the air pressure is used to spread the product completely on the workbench, thereby solving the problem of unstable cutting during the cutting process.

[0008] Furthermore, the mechanical claw is a three-claw bracket, the top of the mechanical claw is connected to the telescopic arm, the damping element is a spherical body with a surface friction coefficient greater than 1, and the damping element can be elastically deformed due to external force. With the above technical solution, the three-claw bracket structure is stable, and the damping ball that increases the friction force can better grasp the release paper by slightly deforming after grasping the release paper.

[0009] Furthermore, the surface roughness of the workbench has a range of Ra of 0.8 to 1.6 μm, so that the friction between the workbench and the material is less than the friction between the damping ball and the material. The above technical solution reduces the friction between the workbench and the release paper, reduces the influence of external factors when the mechanical claw grabs the release paper, makes it easier for the processed material to enter the cutting mechanism, and facilitates the grabbing of the mechanical claw and subsequent transportation.

[0010] Furthermore, the telescopic arm is a hydraulic / pneumatic telescopic actuator connected to an external power source, and outputs force along the telescopic direction of the telescopic arm itself under the drive of the power source. The above technical solution is adopted to extend and retract the telescopic arm through hydraulic telescopic movement, thereby reducing the vibration generated by the telescopic movement inside the mechanical arm during the telescopic movement, and reducing the inability of the mechanical claw to grasp the release paper due to the telescopic movement.

[0011] Furthermore, the air press is connected to the pressure-feeding arm, the area of ​​the air press outputting air pressure is not less than the table area facing the workbench, and the projection area of ​​the air press on the workbench is larger than the projection area of ​​the pressure-feeding arm on the workbench. The above technical solution is adopted to reduce the influence of the pressure-feeding arm resisting part of the air pressure, so that the air pressure generated by the air press acts on the cutting material on the workbench as comprehensively as possible, avoiding the production of defective products due to shaking of the cutting material.

[0012] Furthermore, the box feed port is provided with a cleaning curtain for cleaning the dust of the cutting material and blocking the external dust. The above technical solution is adopted to clean the dust accumulated by the cutting material and avoid the situation that the material is contaminated during the cutting process.

[0013] Furthermore, the top of the box is connected to a dust cover at the edge through a switch snap-on cover, and a viewing window for observing the internal conditions of the box is provided in the horizontal direction of the box. With the above technical solution, the dust cover can be opened actively, which is convenient for carefully observing the internal conditions of the machine, and the internal conditions of the machine can be observed through the viewing window during operation, thereby preventing greater losses caused by problems with the internal machinery.

[0014] The beneficial effect of the present invention is that the device fixes the release paper through the wind pressure generated by the wind press, does not require a complex structure, and can achieve the effect of fixing the processed material with only a single fan machine. The damping member on the pressing arm is brought into contact with the processed material through the conveyor belt, and then the pressing arm connected to the conveyor belt transports the processed material in contact with the damping member to the cutting mechanism as the conveyor belt runs. Only the damping member and the wind pressure generated by the wind press are required to achieve the fixation and transportation of the processed material. Through this solution, the processed material can be completely transported to the next process, which greatly improves the transportation efficiency and more realistically considers the automation standards of the manufacturer in the comprehensive manufacturing process.

DETAILED DESCRIPTION

[0021] The implementation methods of the present invention are described below in conjunction with the accompanying drawings and relevant embodiments. It should be pointed out that the following relevant embodiments are only preferred embodiments for better illustrating the present invention itself, and the implementation methods of the present invention are not limited to the following embodiments, and the present invention involves relevant necessary components in this technical field, which should be regarded as the known technology in this technical field and can be known and mastered by the technical personnel in this technical field.

[0022] See also Figures 1 to 5 As shown, the utility model provides a release paper processing and cutting device, comprising a conveyor belt 1, a wind press 2, a pressure arm 3, a box 6, a connecting rod 304, a cutting mechanism 4 and a workbench 5, wherein the box 6 is provided with a feed port and a discharge port at the head and the end along the material travel direction, and is characterized in that:

[0023] The conveyor belt 1 is arranged on the top of the box body 6 and connected to the pressing arm 3. The air compressor 2 is connected to the top of the box body 6 through the connecting block 201. The workbench 5 is arranged at the bottom of the box body 6 opposite to the output direction of the air compressor 2. The pressing arm 3 is divided into a connecting plate 307, a telescopic arm 302 and a mechanical claw 301, and they are sequentially connected from top to bottom. A threaded hole 303 is provided at the center of the connecting plate 307. The connecting plate 307 is connected to the conveyor belt 1 by a connecting rod 304 and the threaded hole 303. The air compressor 2 is provided with a movable groove for the pressing arm 3 to reciprocate under the driving force of the transmission belt 101. A damping member 308 is provided at the bottom of the mechanical claw 301 for contacting the material. The cutting mechanism 4 is composed of a first cutting roller 401 and a second cutting roller 402, wherein the first cutting roller 401 and the second cutting roller 402 are arranged side by side and tangent to each other, and are symmetrically arranged at the upper and lower positions of the working plane with the working plane of the workbench 5 as a reference.

[0024] The conveyor belt 1 is connected to the air press 2 and the pressing arm 3 of the pressing mechanism 4. The conveyor belt 1 is connected to the air press 2, and the air press 2 is connected to the pressing arm 3. There is an empty groove in the middle of the air press 2 that is sufficient for the pressing arm 3 to be directly connected to the conveyor belt 1. There is a threaded hole 303 on the connecting plate 307 of the pressing arm 3, which can be connected to the threaded hole 303 on the connecting plate 307 through a connecting rod 304. The other end of the connecting rod 304 is connected to the conveyor belt 1, so that the pressing arm 3 is directly connected to the conveyor belt 1, and the conveyor belt 1 works through the transmission belt drive 101. The advantage of such a connection is that as long as the mechanical claw 301 of the pressing arm 3 places the release paper on the workbench 5, the air press 2 can be started immediately. After the mechanical claw 301 of the pressing arm 3 controls the center position of the release paper, the wind pressure blown out by the air press hole 202 can be directly used to flatten and fix the release paper on the workbench 5.

[0025] The structure type of the conveyor belt 1 is a groove type, so that the connecting rod 304 can be stuck on the conveyor belt 1, or the connecting rod 304 can be directly welded to the conveyor belt 1. This option requires the conveyor belt 1 to be made of metal, which will cause the metal material of the conveyor belt 1 to deform during long-term transportation. It can be used as an alternative. Preferably, a rubber conveyor belt 1 can be selected, and the structure is selected as a groove type. A slot for the connecting rod 304 to be clamped is provided on the conveyor belt to fix the pressing arm 3, and the motor provides energy on both sides of the conveyor belt 1 as a conveyor belt drive 101, so that the conveyor belt in the box 6 can be rotated, driving the mechanical claws 301 on the pressing arm 3. At least two conveyor belt drives 101 are required to be fixed on both sides of the box 6. In order to ensure the stability of the conveyor belt 1, the number of conveyor belt drives 101 can be increased, so as to realize the operation of the conveyor belt.

[0026] The mechanical claw 301 is set as a three-claw bracket. Such a bracket has the advantages of good stability and is suitable for a variety of scenarios. The top of the mechanical claw 301 is connected to the telescopic arm 302, and the bottom is provided with a damping member 308 for increasing friction. Generally, a spherical shape is the best. The function of the damping member 308 is to increase the friction with the release paper. Generally speaking, the surface friction coefficient of the damping member 308 should be greater than 1. Even if the surface friction coefficient cannot reach 1 due to external factors, the surface friction coefficient should be increased as much as possible, so that the release paper can be more effectively grasped, and then the mechanical claw 301 is used for transportation. The surface of the workbench 5 is relatively smooth, so In order to reduce the friction with the release paper and avoid excessive friction that affects the grasping and transportation of the mechanical claw 301. Generally speaking, the processing scenario of release paper belongs to interior decoration. Such application scenarios have certain requirements for surface roughness. Ra is 0.8~1.6μm to achieve a smoother surface. If it is larger than this range, due to insufficient smoothness, the adhesion between the workbench 5 and the release paper becomes larger, which may cause the mechanical claw 301 to grasp incorrectly. A smaller range is more suitable for more sophisticated application scenarios, such as precision instruments and optical equipment. In this embodiment, it is not necessary to meet such fine requirements.

[0027] Other machines with air supply function can be used to fix the release paper on the workbench 5. The cutting mechanism 4 is two cutting rollers of the same specification and material. The first cutting roller 401 is set under the workbench 5. The highest point of the first cutting roller 401 is slightly higher than the workbench 5, which is convenient for picking up the material after cutting. The second cutting roller 402 is located at the same vertical position as the first cutting roller 401, which can be more conducive to cutting the material and ensure that after cutting the material, the whole material will not be subjected to forces in other directions and produce irreversible deformation.

[0028] The telescopic arm 302 of the pressing arm 3 can be freely retracted when pressing the cutting material. It adopts the hydraulic telescopic method, and the transmission of the hydraulic telescopic is very stable, with very small impact and vibration, which can reduce the risk of the cutting material caught by the mechanical claw 301 falling off due to the vibration of the pipeline during the telescopic process. The telescopic arm 302 is a first metal tube 305 and a second metal tube 306. When the hydraulic system is started, the hydraulic oil is pushed into the cylinder and pushed into the internal channel through the piston. The first metal tube 306 of the telescopic arm 302 begins to extend, and the whole telescopic process starts. The program can be set to determine the active telescopic height of the telescopic arm 302. The telescopic arm 302 will automatically run according to the set program, avoiding the contact between the pressing arm 3 and the cutting mechanism 4 and causing the machine to be scrapped. Of course, there are many ways to achieve telescopic, such as threaded telescopic and other methods. It only needs to be able to achieve that the pressing arm 3 avoids contact with the cutting mechanism 4. This solution is the most preferred, and there are other solutions for achieving telescopic, such as spiral telescopic, pneumatic telescopic and other solutions.

[0029] The part of cutting the release paper can be replaced by other machines, and does not need to be fixed to the above-mentioned machine specifications, such as a guillotine or other machines.

[0030] The overall operation process is to control the overall structure of the cutting mechanism 4 to obtain the required release paper pattern. After the pre-input, the cutting mechanism 4 can be operated for a preview to confirm whether the pre-input is correct, and then the pressure feeding mechanism is started to cut the release paper.

[0031] After the cutting mechanism 4 completes cutting, the mechanical claw 301 can directly transport the release paper obtained after cutting to the next process, and the waste release paper remaining on the workbench 5 can be cleaned under the workbench 5 by adjusting the wind pressure of the air press 2, which is convenient for manual picking and cleaning, which is simple and easy.

[0032] In another embodiment, there may be two pressing arms 3, which are respectively provided with a feed port and a discharge port of the box body 6. The two pressing arms 3 press and transport the processed materials. The pressing arm 3 near the feed port transports the processed materials to the cutting mechanism 4, and the pressing arm 3 near the discharge port transports the processed materials after cutting to the next process.

[0033] This method can directly eliminate the telescopic arm 302 part in the pressing arm 3, and restrict the two pressing arms 3 to the two sides of the cutting mechanism 4, that is, the feed port and the discharge port of the box 6, thereby preventing the pressing arm 3 from being outdated and causing the telescopic arm 302 to contact the cutting mechanism 4, thereby causing mechanical failure.

[0034] No matter in which embodiment, the air compressor 2 is fixed at a position above the workbench 5 and is not in direct contact with the conveyor belt 1. Instead, it is fixed at the boundary between the box body 6 and the conveyor belt 1 through the connecting block 201. The only item in direct contact with the conveyor belt 1 is the pressure arm 3. This installation method reduces the pressure on the conveyor belt 1 and prevents the conveyor belt 1 from falling off or other problems due to excessive pressure. In addition, the advantage of this setting method is that the air compressor 2 and the pressure arm 3 exist separately. If any one of the components has a problem, the problem can be solved by replacing the parts separately, reducing the maintenance cost and difficulty of maintenance, and facilitating daily maintenance for staff.

[0035] In this embodiment, a dust cover 7 is provided on the top of the box body, which can effectively prevent the flying of dust generated when the cutting material is cut, and can avoid the operator from being affected by the dust. At the same time, the dust cover 7 can be directly opened to disassemble and replace the parts inside the machine. A cleaning curtain 8 is provided at the entrance of the box body 6. When the cutting material comes in, the cleaning curtain 8 will continuously sweep over the cutting material to clean the floating dust and various impurities on the cutting material, making the cutting process simpler and cleaner. An observation window 9 is provided on one side of the box body 6, and the specific working conditions inside the box body can be directly observed through the observation window 9, which is convenient for observing the overall internal conditions of the box body at all times, allowing technicians to observe the working conditions of the overall machine at the first time and then make immediate adjustments.

[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
