Description

Technical Field

[0001] The present application relates to the technical field of die-cutting machines, and specifically to a knife die-cutting rubber mechanism. Background Art

[0002] A die-cutting machine, also known as a cutting machine or a numerical control stamping machine, is mainly used for die-cutting, indentation, hot stamping, laminating, and automatic waste discharging of some non-metallic materials, self-adhesive labels, EVA, double-sided tape, electronics, mobile phone rubber pads, etc. The die-cutting machine uses steel knives, metal molds, steel wires (or templates engraved from steel plates), and applies a certain pressure through an impression plate to cut the printed matter or cardboard into a certain shape, and is an important device for post-printing packaging processing and forming.

[0003] A prior patent (publication number: CN216543510U) discloses a knife group for a tape die-cutting machine, which includes a knife holder and a mounting seat arranged below the knife holder. The knife holder and the mounting seat are movably connected. A slitting table that can move along the mounting seat is arranged on the mounting seat. A plurality of disc knives are rotatably arranged in the knife holder. A plurality of slitting grooves parallel to the disc knives are evenly arranged on the slitting table. The disc knives respectively correspond to but do not contact one of the slitting grooves. In the knife group of the tape die-cutting machine of the present utility model, the disc knives are driven to move by a horizontally movable rotating shaft, and in cooperation with the movement of the slitting grooves, the knife group can be adjusted according to the model width of the tape during slitting without stopping to change the knife, and a plurality of disc knives are synchronously aligned with the slitting grooves, greatly improving the working efficiency during slitting of the knife group, reducing the operation steps, and at the same time, the disc knives cooperating with the slitting grooves can also effectively slow down the colloid adhesion generated when the knife group cuts the tape, improving the yield rate of products.

[0004] However, during cutting, the surface of the disc knife will gradually adhere to the residual glue liquid from cutting, thereby increasing the viscosity of the disc knife. During the rotation of the disc knife, it is easy to drive the cut tape to turn over, resulting in a bonding situation. Secondly, during the cutting process, due to the pressure exerted by the disc knife on the tape, the tape is in a tense state, which causes the cut tape to easily reset quickly, resulting in the bonding of two adjacent tapes. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the present application provides a knife die-cutting rubber mechanism, which has advantages such as anti-bonding, and solves the problems raised in the background art.

[0006] To achieve the above object, the present application provides the following technical solution: A knife die-cutting rubber mechanism includes a bottom plate. Two support seats are fixedly connected to the upper surface of the bottom plate. A limiting tube is rotatably connected between the two support seats. A plurality of equally spaced limiting rings are fixedly connected to the outer surface of the limiting tube. A limiting groove is opened on the outer surface of each limiting ring. A plurality of circumferentially arranged scraping blocks are fixedly connected to the left and right inner side walls of each limiting groove;

A group of first nozzles are fixedly communicated with the outer surface of the limiting tube. A group of second nozzles are fixedly communicated with the outer surface of the cutting tube. Each of the first nozzles and each of the second nozzles are arranged in a cross pattern.

[0008] Through the above solution, by providing a plurality of limiting rings arranged at equal distances on the limiting tube, limiting grooves are provided on the outer surface of each limiting ring, and scraping blocks are equipped. These scraping blocks can continuously clean the surface of the cutting blades when the cutting tube rotates, effectively removing the residual glue during the cutting process, thereby avoiding the problem of tape adhesion caused by the accumulation of glue on the cutting blades. The cross arrangement design of the first nozzles and the second nozzles can perform air flow extrusion on two adjacent tapes after cutting, causing one tape to move upward and the other to move downward, forming a small space interval, effectively preventing the rapid reset and adhesion between the tapes.

[0009] Further, a gantry is fixedly connected to the upper surface of the bottom plate. Two electric push rods are fixedly installed at the bottom of the gantry. The output ends of the two electric push rods are fixedly connected with connection boxes. The two ends of the cutting tube are respectively rotatably connected to the connection boxes close to them.

[0010] Through the above solution, by the setting of the electric push rods, the height of the cutting tube can be adjusted, facilitating the user to place the tape.

[0011] Further, a first motor is installed inside the left connection box. The output end of the first motor is fixedly connected to the left end of the cutting tube.

[0012] Through the above solution, by the setting of the first motor, power can be provided for the rotation of the cutting tube.

[0013] Further, the right end of the cutting tube and the right end of the limiting tube are both rotatably communicated with a connecting tube through a sealing bearing.

[0014] Through the above solution, through the rotational communication of the connecting tube, it can effectively prevent the connecting tube from rotating along.

[0015] Further, the right ends of the two connecting tubes are both fixedly communicated with a hose.

[0016] Through the above solution, by the setting of the hose, it is convenient for the user to connect with an external air source.

[0017] Further, the other ends of the two hoses are both fixedly communicated with the output end of an external air pump.

[0018] Through the above solution, by the setting of the air pump, an air source can be provided for the hose.

[0019] Further, a power shaft is rotatably connected to the left side surface of the support base on the left side. Gears are fixedly connected to the left ends of both the power shaft and the limit tube, and the two gears are meshed with each other.

[0020] Through the above solution, the purpose of transmission can be achieved through the setting of the gears.

[0021] Further, a second motor is fixedly connected to the left end of the upper surface of the bottom plate, and the output end of the second motor is fixedly connected to the left end of the limit tube.

[0022] Through the above solution, through the setting of the second motor, power can be provided for the rotation of the limit tube.

[0023] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0024] For this die-cutting rubber mechanism, by arranging a plurality of equally spaced limit rings on the limit tube, limit grooves are provided on the outer surface of each limit ring, and scraping blocks are equipped. These scraping blocks can continuously clean the surface of the cutting blade when the cutting tube rotates, effectively removing the residual glue during the cutting process, thereby avoiding the problem of tape adhesion caused by the accumulation of glue on the cutting blade. The cross-arrangement design of the first nozzle and the second nozzle can perform air flow extrusion on two adjacent tapes after cutting, causing one tape to move upward and the other to move downward, forming a small spatial interval, effectively preventing the rapid reset and adhesion between the tapes.

A plurality of circumferentially arranged scraping blocks 6 are fixedly connected to the left and right inner side walls of each limiting groove 5.

[0033] Please refer to Figure 1 、 Figure 2 and Figure 4 Above the limiting tube 3, there is a cutting tube 7. A plurality of equally spaced cutting blades 8 are fixedly connected to the outer surface of the cutting tube 7. Through the arrangement of the scraping blocks 6, the purpose of continuously cleaning the surface of the cutting blades 8 can be achieved, effectively avoiding the situation where the cutting blades 8 are adhered by the adhesive liquid and causing the tape to stick. A group of first nozzles 9 are fixedly communicated with the outer surface of the limiting tube 3. A group of second nozzles 10 are fixedly communicated with the outer surface of the cutting tube 7. Each first nozzle 9 and each second nozzle 10 are arranged in a cross pattern. Through the cross arrangement of the first nozzles 9 and the second nozzles 10, the two adjacent tapes after cutting can be squeezed, so that one of the two adjacent tapes moves upward and the other moves downward, effectively avoiding the situation of tape adhesion.

[0034] Please refer to Figure 1 、 Figure 2 and Figure 3 On the upper surface of the bottom plate 1, a gantry 11 is fixedly connected. Two electric push rods 12 are fixedly installed at the bottom of the gantry 11. The output ends of the two electric push rods 12 are fixedly connected with a connection box 13 respectively. The two ends of the cutting tube 7 are rotatably connected to the connection box 13 close to it respectively. Through the arrangement of the electric push rods 12, the height of the cutting tube 7 can be adjusted, which is convenient for the user to place the tape. A first motor 14 is installed inside the left connection box 13. The output end of the first motor 14 is fixedly connected to the left end of the cutting tube 7. Through the arrangement of the first motor 14, power can be provided for the rotation of the cutting tube 7.

[0035] Please refer to Figure 1 、 Figure 2 and Figure 3, the right ends of the cutting tube 7 and the limiting tube 3 are both rotationally connected and communicated with a connecting tube 15 through a sealed bearing. Through the rotational connection and communication of the connecting tube 15, it can effectively prevent the connecting tube 15 from rotating along. The right ends of the two connecting tubes 15 are both fixedly connected and communicated with a flexible tube 16. Through the setting of the flexible tube 16, it is convenient for the user to connect with an external air source. The other ends of the two flexible tubes 16 are both fixedly connected and communicated with the output end of an external air pump. Through the setting of the air pump, it can provide an air source for the flexible tube 16.

[0036] Please refer to Figure 1 , Figure 2 and Figure 3 , the left side surface of the left support base 2 is rotationally connected with a power shaft 17. The left end of the power shaft 17 and the left end of the limiting tube 3 are both fixedly connected with a gear 18. The two gears 18 are meshed and connected. Through the setting of the gear 18, the purpose of transmission can be achieved. The left end of the upper surface of the bottom plate 1 is fixedly connected with a second motor 19. The output end of the second motor 19 is fixedly connected with the left end of the limiting tube 3. Through the setting of the second motor 19, it can provide power for the rotation of the limiting tube 3.

[0037] In a die-cutting rubber mechanism of this embodiment, by arranging a plurality of equally spaced limiting rings 4 on the limiting tube 3, a limiting groove 5 is opened on the outer surface of each limiting ring 4, and a scraping block 6 is equipped. These scraping blocks 6 can continuously clean the surface of the cutting blade 8 when the cutting tube 7 rotates, effectively removing the residual glue during the cutting process, thereby avoiding the problem of tape adhesion caused by the accumulation of glue on the cutting blade 8. The cross-arrangement design of the first nozzle 9 and the second nozzle 10 can perform air flow extrusion on two adjacent tapes after cutting, making one tape move upward and the other move downward, forming a small space interval, effectively preventing the rapid reset and adhesion between the tapes.

[0038] The working principle of the above embodiments is as follows: Place the tape to be cut at an appropriate position on the bottom plate 1. By adjusting the electric push rod 12, lower the cutting tube 7 to an appropriate height to ensure that the cutting blade 8 can contact the surface of the tape. Connect an external air source to the hose 16 to provide a stable air flow for the first nozzle 9 and the second nozzle 10. Start the second motor 19, and transmit the power to the limiting tube 3 through the power shaft 17, causing the limiting tube 3 to start rotating. Since the limiting tube 3 is rotatably connected to the support base 2, and the power shaft 17 on the left support base 2 meshes with the left end of the limiting tube 3 through the gear 18, the limiting tube 3 can rotate smoothly. At the same time, start the first motor 14, transmit the power to the cutting tube 7, causing the cutting tube 7 to also start rotating. The two ends of the cutting tube 7 are respectively rotatably connected to the connection box 13 to ensure the stability during rotation. The scraping block 6 on the limiting ring 4 continuously scrapes the surface of the cutting blade 8 as the cutting tube 7 rotates, removing the residual glue during the cutting process, preventing the cutting blade 8 from losing its cutting effect due to glue accumulation or causing the tape to stick. The first nozzle 9 and the second nozzle 10 are respectively located on the outer surfaces of the limiting tube 3 and the cutting tube 7 and are arranged in a cross pattern. During the cutting process, the external air source enters the nozzles through the hose 16 and the connecting tube 15, and ejects a stable air flow. After the cutting is completed, these air flows squeeze two adjacent tapes, causing one tape to move upward and the other to move downward, forming a small spatial interval, thereby effectively preventing the tapes from quickly resetting and sticking together.
