Description

Technical Field

[0001] The utility model relates to the technical field of slitting machines, and particularly relates to an adsorption device for a slitting machine. Background Technique

[0002] A slitting machine is a device used to cut continuous roll materials or sheet materials into required widths. It is usually used for cutting and processing materials such as paper, plastic film, textiles, and metal foil. The main function of the slitting machine is to cut the original material into required finished products according to the set size or width to meet the processing needs of different industries.

[0003] When cutting materials such as paper, cardboard, packaging materials, plastics, plastic film, and plastic sheets, due to the light texture of the materials, static electricity is generated when the cutting knife rubs against the sheet, which causes the cut materials to be adsorbed on the cutting tool or other components, affecting the cutting effect and product quality. In addition, due to the influence of the accuracy of the equipment itself, there is an incomplete synchronization in the disconnected parts of the materials during the cutting process, that is, some areas are cut first, so that the cut parts will be torn along the seam under the action of gravity, which is likely to form irregular cut edges. Therefore, it is necessary to adsorb and fix the materials.

[0004] However, in the prior art, the adsorption and fixation of materials are mostly realized by using an air pump to supply air to the suction cups. In the actual application process, it requires a large implementation cost, and to meet the adsorption during the cutting process and release the materials during the feeding process, the coordination of actions such as this necessarily requires a complex control system, which greatly increases the implementation cost and operation difficulty and is not conducive to actual application. Summary of the Utility Model

[0005] The purpose of the utility model is to provide an adsorption device for a slitting machine to solve the problems raised in the above background technique.

[0006] To solve the above technical problems, the technical solution adopted by the utility model is:

[0007] An adsorption device for a slitter, comprising a main body; two side mounting frames are symmetrically arranged on one side of the main body, and two feeding rollers are rotatably connected between the closer sides of the side mounting frames. The central axes of the two feeding rollers are driven by gears. A fixing frame is fixedly connected between the closer sides of the side mounting frames. Slide bars are symmetrically and slidably connected to the top of the fixing frame. A backing plate is fixedly connected between the tops of the slide bars. The bottoms of the slide bars all extend below the fixing frame and are fixedly connected with cutting knives. Side plates are fixedly connected to the tops of the side mounting frames. A knife control assembly is arranged on the closer sides of the two side plates. The knife control assembly is used to control the cutting action of the cutting knives. A cutting platform is fixedly connected between the closer sides of the side mounting frames. An adsorption assembly is arranged at the bottom of the cutting platform. The adsorption assembly is used to adsorb the cut coil material. A transmission assembly is arranged on one side of the side mounting frame. The transmission assembly is used to realize the power transmission between the feeding rollers and the knife control assembly. A linkage assembly is arranged between the fixing frame and the cutting platform. The linkage assembly is used to enable the adsorption assembly to move synchronously with the cutting process.

[0008] With the above technical solution, by setting the adsorption assembly, the material during the cutting process can be adsorbed and fixed, thereby avoiding the situation that the material moves due to static electricity or external force during the cutting process, which may cause the cutting to be skewed, improving the cutting effect. At the same time, by setting the transmission assembly and the linkage assembly, the adsorption process, the cutting process, and the feeding process are coordinated. That is, the feeding stops during cutting, and the adsorption action is carried out simultaneously, thus ensuring that the material is not unevenly cut due to feeding during cutting.

[0009] A further improvement of the technical solution of the present utility model lies in that: the knife control assembly includes a rotating rod, the rotating rod is rotatably connected between the closer sides of the two side plates, a cam is fixedly connected to the outer side of the rotating rod, the outer side of the cam is in contact with the top of the backing plate, a spring is sleeved on the outer side of the slide bar, and a motor is fixedly connected to the side of one of the side plates away from the rotating rod. The output end of the motor extends to the other side of the side plate and is fixedly connected to one end of the rotating rod.

[0010] With the above technical solution, by controlling the motor to work, driving the rotating rod to rotate and driving the cam to rotate, and then cooperating with the spring to make the backing plate do reciprocating up and down movements, and driving the cutting knife to do reciprocating up and down movements through the slide bar, the cutting and resetting actions are realized.

[0011] A further improvement of the technical solution of the present utility model lies in that: the adsorption assembly includes a piston cylinder fixedly connected to the bottom of the cutting platform. A piston plate is slidably connected between the inner walls of the piston cylinder. Adsorption holes are arranged on the top of the cutting platform. An air suction pipe is arranged between the piston cylinder and the adsorption holes.

[0012] With the above technical solution, when the piston plate moves downward, a negative pressure will be generated in the piston cylinder, and then the material will be adsorbed through the suction pipe and the adsorption holes. This process exactly corresponds to the cutting action. On the contrary, when the piston plate moves upward to reset, the negative pressure is released and the material is released.

[0013] A further improvement of the technical solution of the present utility model lies in that: the linkage assembly includes a linkage rod, the linkage rod is slidably connected to the top of the cutting platform, the bottom of the linkage rod extends into the interior of the piston cylinder and is fixedly connected to the top of the piston plate, transmission plates are symmetrically and fixedly connected to both sides of the cutting knife, the top of the linkage rod extends above the transmission plates and is fixedly connected to a reset plate, and a pressing plate is fixedly connected to the outer side of the linkage rod.

[0014] With the above technical solution, the cutting knife makes a reciprocating up and down movement along with the cutting action, and at the same time drives the transmission plates to move up and down. When the cutting knife moves downward and makes the transmission plates move downward until they contact and press the pressing plate, at this time the linkage rod moves downward, driving the piston plate to move downward; and when the cutting knife moves upward to reset, the transmission plates move upward until they contact and lift the reset plate, and then drive the piston plate to move upward to reset through the linkage rod.

[0015] A further improvement of the technical solution of the present utility model lies in that: the transmission assembly includes a first pulley, one end of the rotating rod extends to the other side of the side plate and is fixedly connected to the central axis of the first pulley, a second pulley is rotatably connected to one side of the side mounting frame, the second pulley is driven by a belt to be connected to the first pulley, one end of the central axis of the second pulley is fixedly connected to a driving gear, one end of the central axis of the feeding roller extends to the other side of the side mounting frame and is fixedly connected to a driven gear, and the driven gear is meshed and connected to the driving gear.

[0016] With the above technical solution, the rotating rod rotates, and on the one hand, it drives the first pulley to rotate, and drives the second pulley to rotate through belt transmission, making the driving gear rotate, and drives the driven gear to rotate by meshing the toothed part with the driven gear, and then drives the feeding roller to rotate, so that the feeding roller conveys the material.

[0017] A further improvement of the technical solution of the present utility model lies in that: the driving gear is partially toothless.

[0018] With the above technical solution, there is a gap in the transmission process, that is, the driving gear rotates but the driven gear does not rotate during some time periods, and this time period exactly corresponds to the cutting action.

[0019] A further improvement of the technical solution of the present utility model lies in that: a filter screen is arranged inside the adsorption holes.

[0020] With the above technical solution, it is avoided that debris is sucked into the piston cylinder.

[0021] Due to the adoption of the above technical solution, the technical progress achieved by the present utility model compared with the prior art is as follows:

[0022] 1. The present utility model provides an adsorption device for a slitter. By setting an adsorption component, it can adsorb and fix the material during the cutting process, thereby avoiding the situation where the material moves due to static electricity or external force during the cutting process, which may cause the cutting to be skewed, improving the cutting effect. At the same time, by setting a transmission component and a linkage component, the adsorption process, cutting process, and feeding process are coordinated. That is, the feeding stops during cutting, and the adsorption action is carried out simultaneously, thus ensuring that the cutting will not be uneven due to feeding during cutting, and avoiding the problem of irregular cut edges caused by the movement of the material, greatly improving the cutting effect.

[0023] 2. The present utility model provides an adsorption device for a slitter. By setting a transmission component, the cutting process, feeding process, and adsorption process share one drive, so that it is not necessary to use multiple motors in cooperation with a control system for control, and it is not necessary to use an air pump for adsorption, thus greatly saving the implementation cost and being beneficial to practical applications.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] The present invention is further described in detail below in conjunction with the embodiments:

[0032] Example 1

The knife control assembly is used to control the cutting knife 7 to perform cutting action. A cutting platform 23 is fixedly connected between the sides where the side mounting frames 2 are close to each other. An adsorption assembly is provided at the bottom of the cutting platform 23. The adsorption assembly is used to adsorb the cut coil. A transmission assembly is provided on one side of the side mounting frame 2. The transmission assembly is used to realize power transmission between the feeding roller 14 and the knife control assembly. A linkage assembly is provided between the fixed frame 3 and the cutting platform 23. The linkage assembly is used to enable the adsorption assembly to move synchronously with the cutting process.

[0034] In this embodiment, by setting up an adsorption component, the material in the cutting process can be adsorbed and fixed, so as to avoid the movement of materials due to static electricity or external force during the cutting process, which may cause the seam to be skewed, thereby improving the cutting effect. At the same time, by setting up a transmission component and a linkage component, the adsorption process, the cutting process and the feeding process are coordinated, that is, the feeding is stopped during cutting and the adsorption action is performed at the same time, thereby ensuring that the material will not be unevenly cut due to feeding during cutting, and avoiding the problem of irregular cutting edges due to material movement, thereby greatly improving the cutting effect.

[0035] Example 2

[0036] like Figure 2 and Figure 5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the knife control assembly includes a rotating rod 9, which is rotatably connected between the two sides of the side plates 8 that are close to each other, and a cam 10 is fixedly connected to the outer side of the rotating rod 9, and the outer side of the cam 10 contacts the top of the pad 6, and a spring 5 is sleeved on the outer side of the slide rod 4, and a motor 11 is fixedly connected to the side of one side plate 8 away from the rotating rod 9, and the output end of the motor 11 extends to the other side of the side plate 8 and is fixedly connected to one end of the rotating rod 9.

[0037] In this embodiment, by controlling the operation of the motor 11, the rotating rod 9 is driven to rotate, driving the cam 10 to rotate. Furthermore, it will cooperate with the spring 5 to make the backing plate 6 perform reciprocating up and down movements, and drive the cutting knife 7 to perform reciprocating up and down movements through the slide rod 4, realizing the cutting and resetting actions.

[0038] Embodiment 3

[0039] As Figure 3 and Figure 5 shown, on the basis of Embodiment 2, the present utility model provides a technical solution: Preferably, the adsorption assembly includes a piston cylinder 17 fixedly connected to the bottom of the cutting platform 23. A piston plate 18 is slidably connected between the inner walls of the piston cylinder 17. An adsorption hole 24 is provided at the top of the cutting platform 23. An air suction pipe 20 is provided between the piston cylinder 17 and the adsorption hole 24.

[0040] In this embodiment, when the piston plate 18 moves downward, a negative pressure will be generated in the piston cylinder 17. Furthermore, the material is adsorbed through the air suction pipe 20 and the adsorption hole 24. This process exactly corresponds to the cutting action; conversely, when the piston plate 18 resets upward, the negative pressure is released and the material is released.

[0041] Embodiment 4

[0042] As Figure 4 and Figure 5 shown, on the basis of Embodiment 3, the present utility model provides a technical solution: Preferably, the linkage assembly includes a linkage rod 19. The linkage rod 19 is slidably connected to the top of the cutting platform 23. The bottom of the linkage rod 19 extends into the interior of the piston cylinder 17 and is fixedly connected to the top of the piston plate 18. Transmission plates 25 are symmetrically and fixedly connected to both sides of the cutting knife 7. The top of the linkage rod 19 extends above the transmission plates 25 and is fixedly connected to a reset plate 22. A pressing plate 21 is fixedly connected to the outside of the linkage rod 19.

[0043] In this embodiment, the cutting knife 7 performs reciprocating up and down movements along with the cutting action, and at the same time drives the transmission plates 25 to move up and down. When the cutting knife 7 moves downward and makes the transmission plates 25 move downward until they contact and press the pressing plate 21, at this time the linkage rod 19 moves downward, driving the piston plate 18 to move downward; and when the cutting knife 7 resets upward, the transmission plates 25 move upward until the transmission plates 25 contact and lift the reset plate 22, and then drive the piston plate 18 to reset upward through the linkage rod 19.

[0044] Embodiment 5

[0045] As Figure 2 and Figure 5As shown, on the basis of Embodiment 4, the present utility model provides a technical solution: Preferably, the transmission assembly includes a first pulley 12. One end of the rotating rod 9 extends to the other side of the side plate 8 and is fixedly connected to the central axis of the first pulley 12. One side of the side mounting bracket 2 is rotatably connected to a second pulley 13. The second pulley 13 is driven by a belt in connection with the first pulley 12. One end of the central axis of the second pulley 13 is fixedly connected to a driving gear 15. One end of the central axis of the feeding roller 14 extends to the other side of the side mounting bracket 2 and is fixedly connected to a driven gear 16. The driven gear 16 is meshed and connected with the driving gear 15.

[0046] In this embodiment, when the rotating rod 9 rotates, on the one hand, it drives the first pulley 12 to rotate, and drives the second pulley 13 to rotate through belt transmission, so that the driving gear 15 rotates, and drives the driven gear 16 to rotate by meshing with the toothed part of the driven gear 16, and then drives the feeding roller 14 to rotate, so that the feeding roller 14 conveys materials.

[0047] As Figure 2 and Figure 5 shown, preferably, a part of the driving gear 15 has no teeth.

[0048] In this embodiment, there is a gap in the transmission process, that is, the driving gear 15 rotates but the driven gear 16 does not rotate during a certain period of time, and this period of time exactly corresponds to the cutting action.

[0049] As Figure 5 shown, preferably, a filter screen is arranged inside the adsorption hole 24.

[0050] In this embodiment, debris is prevented from being sucked into the piston cylinder 17.

[0051] Next, the working principle of the adsorption device for the slitter will be specifically described.

[0052] As Figures 1-5 shown, the material passes between the two feeding rollers 14. By controlling the operation of the motor 11, the rotating rod 9 is driven to rotate. On the one hand, it drives the first pulley 12 to rotate, and drives the second pulley 13 to rotate through belt transmission, so that the driving gear 15 rotates, and drives the driven gear 16 to rotate by meshing with the toothed part of the driven gear 16, and then drives the feeding roller 14 to rotate, so that the feeding roller 14 conveys materials. When the toothless part of the driving gear 15 approaches the driven gear 16, the two are no longer meshed, and thus no transmission occurs. At this time, the feeding roller 14 stops rotating (stopping feeding, and at this time, the cutting operation and the adsorption action are performed), and then meshes again as the toothed part approaches the driven gear 16;

[0053] On the other hand, the rotation of the rotating rod 9 drives the rotation of the cam 10, which in turn cooperates with the spring 5 to make the backing plate 6 move up and down reciprocally, and drives the cutting knife 7 to move up and down reciprocally through the sliding rod 4, realizing the cutting and resetting actions. At the same time, the driving plate 25 is driven to move up and down. When the cutting knife 7 moves downward and makes the driving plate 25 move downward until it contacts and presses the pressing plate 21, at this time, the linkage rod 19 moves downward, driving the piston plate 18 to move downward, generating negative pressure in the piston cylinder 17, and then adsorbing the material through the suction pipe 20 and the adsorption holes 24. This process exactly corresponds to the cutting action. When the cutting knife 7 resets upward, the driving plate 25 moves upward until the driving plate 25 contacts and lifts the reset plate 22, and then drives the piston plate 18 to reset upward through the linkage rod 19, releasing the negative pressure and releasing the material.

[0054] The above text has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit and idea of the present utility model are within the protection scope of the present utility model.
