Description

Technical Field

[0001] The present invention relates to the technical field of slitting machines, and particularly to a slitting machine for adhesive production. Background Art

[0002] In the production process of adhesive materials, the slitting machine is a key post-processing equipment. Its function is to process wide raw materials into narrow finished coils with specific widths through processes such as slitting and rewinding to meet the needs of end applications. The accuracy, efficiency, and stability of the slitting machine directly affect the product qualification rate and production cost.

[0003] After retrieval, a Chinese patent with the publication number CN213864676U discloses a slitting machine. The conveyor roller of this device facilitates the transportation of strip-shaped products, and the cutting assembly on the rotating shaft facilitates the cutting of products. The conveyor roller facilitates the transportation of the cut products, which is conducive to improving production efficiency. The scale value on the rotating shaft facilitates the staff to adjust the position of the blade, and the moving assembly facilitates the movement of the blade to improve the cutting accuracy. However, there are still the following problems:

[0004] 1. When the blade performs long-term slitting operations on materials, residues such as residual glue of the materials are likely to adhere to its blade edge. If not processed in time, it will affect the sharpness of the blade, and then in the slitting process, the materials will be squeezed, resulting in the materials not being effectively and evenly slit. Therefore, how to solve the problem of cleaning the residues on the blade is an urgent problem to be solved.

[0005] 2. When cleaning the residues on the blade, generally the slitting machine needs to be stopped to manually clean the residues on the blade. However, during the cleaning process, the slitting machine cannot work, which will greatly affect the working efficiency of the slitting machine. Therefore, how to clean the residues on the blade without affecting the normal operation of the slitting machine is an urgent problem to be solved now.

[0006] 3. During the cleaning process of the residues on the blade, cleaning items are needed. And during the long-term cleaning process, a large amount of residues will remain on them. If there are too many residues, the blade cannot be thoroughly cleaned. Therefore, how to quickly replace the cleaning items is also an urgent problem to be solved now. Summary of the Invention

[0007] Technical Problems to be Solved

[0008] In view of the deficiencies of the prior art, the present invention provides a slitting machine for adhesive production, mainly to solve the problem that when the blade cuts materials for a long time, residues such as residual glue are likely to adhere to the blade edge.

When cleaning the residues on the blade, generally the slitting machine needs to be stopped and the residues on the blade are cleaned manually. However, during the cleaning process, the slitting machine cannot work, which will greatly affect the working efficiency of the slitting machine and the cleaning items required during the cleaning of the residues on the blade. And during the long-term cleaning process, a large amount of residues will remain on it. If there are more residues, the blade cannot be thoroughly cleaned.

[0046] To solve the problem of residual glue on the blade, in the present invention, the glue cleaning assembly 12 includes end seats 1201 slidably connected to both ends of the carriage 11. Two sets of symmetric slide bars 1202 are fixedly connected between the two end seats 1201 by bolts, and each set has two slide bars. A slide plate 1203 is slidably connected to the multiple slide bars 1202. One side of the slide plate 1203 is detachably connected with a fixing assembly 1204 by bolts. Two sponges 1205 are arranged in the fixing assembly 1204. The other side of the slide plate 1203 is fixedly connected with a liquid storage box 1211 storing degumming liquid by bolts. On one side of the carriage 11, two symmetric fixing blocks two 1206 are fixedly connected by bolts.

At one end of the lower surface of the slide plate 1203, a semi-circular plate two 1209 is fixedly connected by bolts.

The heating assembly 13 includes a mounting frame 1301 fixedly connected to the outer wall of one side of the U-shaped plate 8 by bolts. At both ends of one side of the mounting frame 1301, motor seats 1302 are fixedly connected by bolts. Belt pulleys 1303 are rotatably connected between the inner walls on both sides of the two motor seats 1302. The two belt pulleys 1303 are driven by a belt 1304. On the outer wall of one side of one of the motor seats 1302, a driving motor 1308 for rotating one of the belt pulleys 1303 is fixedly connected by bolts. On one side of the mounting frame 1301, a guide rail 1306 is fixedly connected by bolts. A slider 1305 cooperating with the belt 1304 is slidably connected to the guide rail 1306. One side of the slider 1305 is fixedly connected with a heating plate 1307 by bolts. The fixing assembly 1204 includes an end plate one 12041 fixedly connected to one end of the upper surface of the slide plate 1203 by bolts. On one side of the end plate one 12041, two sets of limiting rods 12042 are fixedly connected by bolts, and each set has two limiting rods. On one side of the end plate one 12041 and between the two sets of limiting rods 12042, a square plate 12043 and a square frame 12044 are respectively fixedly connected by bolts. Positioning openings 12051 are formed on both of the two sponges 1205. The square plate 12043 and the square frame 12044 respectively pass through the positioning openings 12051 of the two sponges 1205. The other ends of the two sets of limiting rods 12042 are detachably connected with an end plate two 12045 by bolts. A liquid inlet pipe 12111 cooperating with the liquid storage box 1211 is arranged on the liquid storage box 1211. An air charging head 12112 connected to an external air pipe is arranged at one end of the liquid storage box 1211. A plurality of connecting pipes 12113 cooperating with the liquid storage box 1211 are arranged on one side of the liquid storage box 1211, and cross silicone valves are arranged in the plurality of connecting pipes 12113. The connecting pipes 12113 pass through the slide plate 1203 and cooperate with one of the sponges 1205.After the rotating shaft 507 rotates 180 degrees, it will drive the tool holder 504 on the square tool path 503 to rotate 180 degrees, thereby switching the two sets of slitting knives 505 on it. Subsequently, air is input into the liquid storage box 1211 through an external air pipe, thereby increasing the air pressure in the liquid storage box 1211 so that the degumming liquid inside it is squeezed into one of the sponges 1205 through the connecting pipe 12113. Through the provided liquid storage box 1211, the connecting pipe 12113 on it, and the cross-shaped silica gel valve inside it, the degumming liquid inside it can only be squeezed onto the sponge 1205 when gas is introduced, avoiding waste of the degumming liquid and soaking the sponge 1205 with the degumming liquid. Subsequently, start the rotating motor 704 to drive the U-shaped plate 8 to rotate, thereby making the bottom slitting knife 505 cut into the soaked sponge 1205. At this time, the degumming liquid in the sponge 1205 adheres to the slitting knife 505, and then the degumming liquid reacts with the glue to perform the degumming operation. Subsequently, start the rotating motor 704 again to drive the U-shaped plate 8 to rotate 180 degrees in the reverse direction so that the heating component 13 on it reaches the range of the bottom slitting knife 505. Through the combined use of the slitting component 5 and the glue cleaning component 12, the glue on the other set of slitting knives 505 can be cleaned while one set of slitting knives 505 is working, and the normal operation of the device is not affected during the cleaning process, greatly increasing the efficiency of the device for slitting materials. Then start the driving motor 1308 to drive the belt pulley 1303 to rotate. During the rotation of the belt pulley 1303, the slider 1305 is driven to move along the guide rail 1306 through the belt 1304. At the same time, turn on the heating plate 1307 on the slider 1305 to slightly heat the slitting knife 505. Through the provided heating component 13, the slitting knife 505 can be slightly heated to make the degumming liquid react quickly with the glue, reducing the time consumed by the reaction and further increasing the degumming efficiency. After the heating is completed, start the rotating motor 704 again to drive the U-shaped plate 8 to rotate 180 degrees in the positive direction, so that the soaked sponge 1205 contacts the bottom slitting knife 505 again, wiping the residue on it and cooling the slitting knife 505 at the same time. Subsequently, start the electric telescopic rod 1207 to extend and retract. During the extension and retraction of the electric telescopic rod 1207, the end slide seat 1201 is pushed to move along the slide frame 11, so that another dry sponge 1205 contacts the slitting knife 505. Continue to start the electric telescopic rod 1207 to extend so that the slitting knife 505 cuts into the dry sponge 1205 to adsorb the remaining liquid. Through the provided two sponges 1205, the slitting knife 505 can be wetted and dried respectively, preventing the remaining degumming liquid on the slitting knife 505 from being brought to the material and damaging the material. After the adsorption of the remaining liquid on the slitting knife 505 is completed, start the rotating motor 704 to drive the U-shaped plate 8 to rotate 90 degrees to avoid the slitting knife 505. Wait until the upper and lower sets of slitting knives 505 are switched again, and then start the rotating motor 704 to drive the U-shaped plate 8 to rotate to clean the glue on the other set of slitting knives 505, and so on.When avoiding the position after the cleaning of a set of cutting knives 505 is completed after the sponge 1205 is used multiple times, the multi-joint electric telescopic rod two 1210 is started to expand and contract, thereby driving the sliding plate 1203 to slide along the sliding frame 11. During the sliding process of the sliding plate 1203, the sponge 1205 thereon will be driven to move, thereby changing its contact position with the cutting knife 505. By providing the sliding frame 11 and the multi-joint electric telescopic rod two 1210, the contact position between the sponge 1205 and the cutting knife 505 can be changed, so that the sponge 1205 can be conveniently reused, saving resources and avoiding waste.

[0047] The degreasing liquid can be industrial alcohol, acetone, special degreasing agent and ethyl acetate.

Connecting seats 702 are fixedly connected to the movers of the two linear motor modules 701 by bolts. Square tubes 703 are fixedly connected to one side of the two connecting seats 702 by bolts. The two ends of the U-shaped plate 8 are respectively rotatably connected to one side of the two square tubes 703. A rotating motor 704 for rotating the U-shaped plate 8 is fixedly connected to the inner wall of one side of one of the square tubes 703 by bolts. The telescopic assembly 9 includes two symmetric square telescopic rods 901 fixedly connected to the inner wall of one side of the U-shaped plate 8 by bolts, and the other ends of the square telescopic rods 901 are fixed to one side of the connecting frame 10. A U-shaped frame 902 is slidably connected to the middle part of the sliding frame 11. A multi-joint electric push rod 903 is fixedly connected between the outer wall of one side of the U-shaped frame 902 and the inner wall of one side of the U-shaped plate 8 by bolts. When the sponge 1205 is used multiple times and reaches the loss standard, the device is stopped, the linear motor module 701 is started, and its mover moves downward along the track to the lowest end. The rotating motor 704 is started to drive the U-shaped plate 8 to rotate so that the part with the sponge 1205 is close to the front side of the device. Then the multi-joint electric push rod 903 is started to extend. During the extension process of the multi-joint electric push rod 903, the sliding frame 11 thereon is driven to move, and the sponge 1205 is sent to the outside of the device. Then the end plate two 12045 is removed, and the two sponges 1205 are respectively slid out along the square plate 12043 and the square frame 12044. After removing the sponge 1205, a new sponge 1205 is installed, and the above steps are operated in reverse to complete the replacement operation of the sponge 1205. At the same time, check the degreasing liquid in the liquid storage box 1211. If the stock is less, it needs to be added. By using the moving and rotating assembly 7 and the telescopic assembly 9 in cooperation, the sponge 1205 on the sliding plate 1203 can be sent to the outside of the device, so as to facilitate the staff to replace the damaged sponge 1205.

[0049] The present invention is used in the following steps:

[0050] S1: When in use, first place the material to be slit on the feeding roller 2, then pass the material through multiple guiding rollers 4 and slit it through the slitting assembly 5 and connect it to the two winding rollers 3. Start the reduction motor to make the feeding roller 2 and the winding rollers 3 work, and slit the material through the slitting assembly 5. During the slitting process, glue will adhere to the slitting knife 505;

[0051] S2: During the process of cleaning the glue, first start the stepping motor 510 to drive the connecting shaft 507 to rotate 180 degrees, and at the same time make the square block 604 on it rotate 180 degrees. After the connecting shaft rotates 180 degrees, start the two cylinders 602 to extend simultaneously. During the extension of the two cylinders 602, drive the clamping plate 603 to move synchronously to clamp the square block 604, and then position the connecting shaft 507;

[0052] S3: After the rotating shaft 507 rotates 180 degrees, it will drive the tool holder 504 on the square tool rail 503 to rotate 180 degrees, and then switch the two groups of slitting knives 505 on it. Then, input air into the liquid storage box 1211 through an external air pipe, thereby increasing the air pressure in the liquid storage box 1211 and squeezing the degumming liquid inside it through the connecting pipe 12113 into one of the sponges 1205, making this sponge 1205 soaked with the degumming liquid. Then start the rotating motor 704 to drive the U-shaped plate 8 to rotate, and then make the bottom slitting knife 505 slide into the soaked sponge 1205. At this time, the degumming liquid in the sponge 1205 adheres to the slitting knife 505, and then the degumming liquid reacts with the glue to perform the degumming operation;

[0053] S4: Then start the reverse rotating motor 704 again to drive the U-shaped plate 8 to rotate 180 degrees so that the heating component 13 on it reaches the range of the bottom slitting knife 505. Then start the driving motor 1308 to drive the belt pulley 1303 to rotate. During the rotation of the belt pulley 1303, drive the slider 1305 to move along the guide rail 1306 through the belt 1304, and at the same time turn on the heating plate 1307 on the slider 1305 to slightly heat the slitting knife 505;

[0054] S5: After the heating is completed, start the rotating motor 704 again to drive the U-shaped plate 8 to rotate forward 180 degrees, so that the soaked sponge 1205 contacts the bottom slitting knife 505 again, wipes the residue on it and cools down the slitting knife 505 at the same time. Then start the electric telescopic rod 1207 to expand and contract. During the expansion and contraction of the electric telescopic rod 1207, push the end slide seat 1201 to move along the slide frame 11, so that another dry sponge 1205 contacts the slitting knife 505. Continue to start the electric telescopic rod 1207 to extend and make the slitting knife 505 slide into the dry sponge 1205 to adsorb the remaining liquid;

[0055] S6: After the liquid remaining on the slitting knife 505 is adsorbed, start the rotating motor 704 to drive the U-shaped plate 8 to rotate 90 degrees, thereby avoiding the slitting knife 505. When the upper and lower groups of slitting knives 505 are switched again, start the rotating motor 704 to drive the U-shaped plate 8 to rotate, thereby cleaning the glue on the other slitting knife 505, and so on;

[0056] S7: When the sponge 1205 has been used many times and is in the process of avoiding the position after cleaning one group of slitting knives 505, start the multi-section electric telescopic rod two 1210 to expand and contract, thereby driving the slide plate 1203 to slide along the slide frame 11. During the sliding of the slide plate 1203, the sponge 1205 thereon will be driven to move, thereby changing its contact position with the slitting knife 505;

[0057] S8: When the sponge 1205 has been used many times and reaches the loss standard, stop the device. Start the linear motor module 701, and its mover moves downward along the track to the lowest end. Start the rotating motor 704 to drive the U-shaped plate 8 to rotate, just make the part with the sponge 1205 close to the front side of the device. Then start the multi-section electric push rod 903 to extend. During the extension of the multi-section electric push rod 903, drive the slide frame 11 thereon to move, send the sponge 1205 to the outside of the device. Then remove the end plate two 12045 and slide the two sponges 1205 out along the square plate 12043 and the square frame 12044 respectively. After removing the sponge 1205, install a new sponge 1205, and reverse the above steps to complete the replacement operation of the sponge 1205. At the same time, check the degumming liquid in the liquid storage box 1211. If the stock is less, it needs to be added.
