Description

Technical Field

[0001] This application relates to the field of paper-aluminum-plastic processing, and in particular to a paper-aluminum-plastic slitting device. Background Technology

[0002] Paper-aluminum-plastic composite material (referred to as "paper-aluminum-plastic") is a multi-layer composite packaging material made of paper, aluminum foil, and plastic film through a composite process. This material combines the printability of paper, the oxygen / moisture barrier properties of aluminum foil, and the moisture-proof and puncture-resistant properties of plastic film. It is widely used in food, pharmaceuticals, and daily chemical products. A paper-aluminum-plastic slitting device is a specialized machine used to slit paper-aluminum-plastic composite materials into specific widths or shapes.

[0003] For example, patent application number 202323533372.4 discloses an aluminum-plastic composite strip cutting device, but it still has the following shortcomings in practical use:

[0004] The above-mentioned device feeds aluminum-plastic composite strip by driving the feeding roller with motor one, and drives the cutting blade to adjust and cut by driving motor two with cylinder. The winding section completes the winding and surface dust removal of the cut strip. During use, it is difficult to clean the dust on the surface of the cutting blade in stages and to lubricate it in a timely manner. The continuous accumulation of dust will reduce the cutting accuracy and efficiency, wear the blade, and shorten the cutting blade life. Insufficient lubrication will increase the friction of the blade strip, aggravate the wear of the cutting blade, and affect the cutting quality. Utility Model Content

[0005] In order to improve the dust removal and lubrication of the cutter during use, this application provides a paper-aluminum-plastic slitting device.

[0006] The paper-aluminum-plastic slitting device provided in this application adopts the following technical solution:

[0007] A paper-aluminum-plastic composite slitting device includes a slitting machine body and fixed plates fixed at both ends on one side of the slitting machine body. A rotating shaft is rotatably arranged in the middle of the fixed plate. A cutting blade for cutting paper-aluminum-plastic composite material is fixedly sleeved on the surface of the rotating shaft. A cleaning and lubrication mechanism for cleaning and lubricating the surface of the cutting blade is movably arranged on one side of the cutting blade. The cleaning and lubrication mechanism includes a cleaning seat and a screw rod movably inserted through the middle of one side of the cleaning seat. Clamping blocks are slidably arranged on both sides of the cleaning seat near the screw rod.

[0008] By adopting the above technical solution, the device drives the cutting blade to cut composite materials through the rotating shaft on the fixed plate, and cleans and lubricates the surface of the cutting blade through the cleaning seat, screw and clamp in the cleaning and lubrication mechanism.

[0009] Preferably, a nut is movably disposed in the middle of the cleaning seat, and the end of the nut near the screw is threaded onto the screw.

[0010] By adopting the above technical solution, the nut and the screw are threaded together, and rotating the nut facilitates the horizontal movement of the screw, which is the main power source of the entire cleaning and lubrication mechanism, and facilitates the subsequent cleaning of the cutting blade surface by the linked cleaning sponge.

[0011] Preferably, the cleaning seat is fixed with limiting seats on both sides near the screw end, and the ends of the two clamping blocks near the two limiting seats slide inside the limiting seats.

[0012] By adopting the above technical solution, the two limit seats facilitate the guiding and limiting of the sliding of the clamping block, ensuring that the clamping block slides stably and linearly on both sides of the cleaning seat near the screw, which facilitates the smooth operation of the cleaning and lubrication mechanism.

[0013] Preferably, the screw has transmission rods rotatably mounted on both the upper and lower sides of the end away from the cleaning seat, and the ends of the two transmission rods away from the screw are respectively rotatably mounted in the middle of the clamping block.

[0014] By adopting the above technical solution, the transmission rod connects the screw and the clamping block, which facilitates the linkage between the screw and the clamping block. When the screw rotates, the rotational motion can be converted into linear sliding of the clamping block within the limiting seat.

[0015] Preferably, a cleaning sponge is movably provided on the opposite side of the two clamping blocks away from the limiting seat, and an insert block inserted into the two cleaning sponges is fixedly provided on the two clamping blocks at the middle position of the cleaning sponge.

[0016] By adopting the above technical solution, the two clamping blocks are securely inserted into the cleaning sponge with the help of the inserting blocks, so that the cleaning sponge is fixed on the opposite side of the two clamping blocks, making it easy to fit onto the surface of the cutting blade as the clamping blocks move.

[0017] Preferably, an oil supply pipe is fixedly provided through the middle of the top of each of the two limiting seats, and an oil tank is fixedly provided through the top of the two oil supply pipes.

[0018] By adopting the above technical solution, the oil tank delivers lubricating oil to the inner cavity of the clamping block through an oil supply pipe fixed in the middle of the top of the two limit seats, providing a source of lubricating oil for cleaning the sponge and lubricating the cutting knife.

[0019] Preferably, a fixing block is fixed to the upper side of the oil tank.

[0020] By adopting the above technical solution, the fixing block provides an installation connection point for the oil tank, which facilitates the stable assembly of the oil tank and the entire cleaning and lubrication mechanism in the corresponding position of the cutting device.

[0021] Preferably, a fixing frame is fixedly provided at the upper middle part of the fixing plate, the fixing block is fixed to the fixing frame on the side facing the fixing frame, and a conveying roller is rotatably provided in the middle part of the fixing plate directly below the cutting blade.

[0022] By adopting the above technical solution, the fixed block is connected to the fixed frame to support the oil tank and ensure the stability of the cleaning and lubrication mechanism. The conveyor roller facilitates the transport of paper-aluminum-plastic composite material to the cutting position, and works with the cutting blade to complete the slitting.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By rotating the nut, the screw is driven to move towards the nut, causing the clamping block to move towards the limit seat. Since the rotating rod passes through the two transmission rods and one end of the screw, it drives the end of the clamping block equipped with the cleaning sponge to open and close. When the oil injection hole two coincides with the bottom end of the oil supply pipe, lubricating oil flows from the inside of the oil tank to the inner cavity of the clamping block and flows out from the oil injection hole one to the surface of the cleaning sponge. During the cutting operation, this mechanism facilitates the phased cleaning of dust on the surface of the cutting blade according to actual needs, effectively removing impurities attached to the cutting blade, ensuring that the cutting blade is always kept clean, and providing good lubrication for the cutting blade. This reduces the wear caused by friction during high-speed operation of the cutting blade and effectively extends the service life of the cutting blade. The cooperation between the insert block and the insert hole facilitates the replacement of the cleaning sponge, improving the convenience and practicality of the device. Attached Figure Description

[0034] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0035] This application discloses a paper-aluminum-plastic slitting device.

[0036] Reference Figure 1 , Figure 2 A paper-aluminum-plastic composite slitting device includes a slitting machine body 1 and fixed plates 5 fixed at both ends on one side of the slitting machine body 1. A rotating shaft 6 is rotatably mounted in the middle of the fixed plate 5. A cutting blade 3 is fixedly sleeved on the surface of the rotating shaft 6. The cutting blade 3 is used to cut the paper-aluminum-plastic composite material. A cleaning and lubrication mechanism 2 is movably mounted on one side of the cutting blade 3. The cleaning and lubrication mechanism 2 is used to clean dust from the surface of the cutting blade 3 and to lubricate the cutting blade 3 during operation, preventing damage to the cutting blade 3 caused by prolonged friction. For cutting precision, a fixed frame 4 is fixedly installed at the upper middle part of the fixed plate 5. A conveyor roller 8 is rotatably installed in the middle of the fixed plate 5 directly below the cutting blade 3. A take-up roller 7 is rotatably installed in the middle of the fixed plate 5, located between the conveyor roller 8 and the outer side of the cleaning and lubrication mechanism 2. A feeding roller 9 is fixedly installed at the end of the slitting machine body 1 away from the fixed plate 5. The feeding roller 9 is used to convey the paper-aluminum-plastic composite material to the processing station at a constant speed. A motor is installed at the bottom of the slitting machine body 1 to drive the rotating shaft 6, feeding roller 9, take-up roller 7 and conveyor roller 8 to rotate.

[0037] Before use, multiple cutting blades 3 are fixed on the rotating shaft 6 as needed, and the same number of cleaning and lubrication mechanisms 2 are installed at the lower end of the fixed frame 4 on one side of the cutting blades 3. When in use, the motor is started to drive the feeding roller 9 to rotate, so that the paper aluminum-plastic composite material is conveyed to the conveying roller 8 and the winding roller 7 at a constant speed. The rotating shaft 6 drives the cutting blades 3 to rotate and cut the paper aluminum-plastic composite material. During the operation of the device, the cleaning and lubrication mechanism 2 is operated to clean and lubricate the cutting blades 3 in stages as needed.

[0038] Reference Figures 3-6The cleaning and lubrication mechanism 2 includes a cleaning seat 201 and a screw 202 that is movably inserted through the middle of one side of the cleaning seat 201. A nut 203 is movably disposed in the middle of the cleaning seat 201. The two ends of the nut 203 are respectively in low contact with the inner wall of the cleaning seat 201. The inside of the nut 203 has a threaded groove that matches the thread on the surface of the screw 202. The end of the nut 203 near the screw 202 is threaded onto the screw 202. Rotating the nut 203 causes the screw 202 to move horizontally along the direction of the nut 203. Clamping blocks 205 are provided on both sides of the end of the cleaning seat 201 near the screw 202. The clamping blocks 205 are generally L-shaped (e.g., ...). Figure 3 As shown, the cleaning seat 201 is fixed with limiting seats 204 on both sides near the screw 202. The middle of the two limiting seats 204 is provided with a rectangular groove that matches the shape of the clamping block 205. The ends of the two clamping blocks 205 near the two limiting seats 204 slide inside the rectangular groove.

[0039] In use, rotating the nut 203 drives the screw 202 to move horizontally in the middle of the cleaning seat 201, causing the two transmission rods 207 to rotate and move laterally around the rotating rod 208, which in turn drives the two clamping blocks 205 to slide inside the limiting seat 204. This causes the ends of the two clamping blocks 205 near the cleaning sponge 206 to move closer to each other, and the two cleaning sponges 206 to move closer to the two sides of the cutting blade 3. When the cutting blade 3 rotates, it is convenient to clean the dust on the surface of the cutting blade 3.

[0040] The screw 202, located away from the cleaning seat 201, has transmission rods 207 rotatably mounted on both its upper and lower sides. The screw 202, located away from the cleaning seat 201, and the two transmission rods 207, located near the screw 202, each have a circular hole (I). These three circular holes (I) overlap each other. A rotating rod (I) 208 is movably inserted through the center of each of the three circular holes (I). The screw 202 and one end of each of the two transmission rods 207 are movably fitted onto the rotating rod (I) 208. The two clamping blocks 205, located in their middle sections, and the two transmission rods 207, located away from the screw 202, each have a circular hole (II). The circular holes on the surfaces of the two transmission rods 207 and the two clamping blocks 205 are also... The two pairs of circular holes 207 overlap, and rotating rods 209 are movably inserted through each pair of circular holes 207. The ends of the two transmission rods 207 away from the screw 202 and the middle parts of the two rotating rods 209 are respectively movably fitted onto the two rotating rods 209. The ends of the two clamping blocks 205 away from the limiting seat 204 are each provided with a slot 217 on opposite sides. A cleaning sponge 206 is movably installed on opposite sides of the two slots 217. An insert block 215 is fixed in the middle of the two slots 217. An insertion hole 216 is provided in the middle of the opposite side of the two cleaning sponges 206. The shape of the two insertion holes 216 is perfectly matched with the shape of the two insert blocks 215 (e.g., ...). Figure 6 As shown, two plugs 215 are inserted into two sockets 216.

[0041] By pulling the cleaning sponge 206 outward, the insertion hole 216 in the middle of the cleaning sponge 206 is squeezed and deformed, thereby causing the insertion block 215 to detach from the insertion hole 216. The new cleaning sponge 206 is then installed into the slot 217 through the cooperation of the insertion block 215 and the insertion hole 216.

[0042] Two slots 217 have an oil injection hole 214 located in the middle of one side of the insert block 215, for delivering lubricating oil into the cleaning sponge 206. Two limit seats 204 each have an oil supply pipe 212 fixedly inserted through their top center. The bottom ends of the two oil supply pipes 212 are flush with the inner top surfaces of the two limit seats 204. Two clamping blocks 205 have an oil injection hole 218 on their top surface away from the cleaning sponge 206. The diameter of the two oil injection holes 218 is the same as the inner diameter of the two oil supply pipes 212. The two oil injection holes 218 and the oil supply pipes 212... The distance between 12 is the same as the distance between the two cleaning sponges 206 when they move from their initial position to both sides of the cutting blade 3. The top ends of the two oil pipes 212 are connected and fixed to an oil tank 210. An oil inlet is provided in the middle of the top end of the oil tank 210. The oil inlet is used to fill the inner cavity of the oil tank 210 with lubricating oil. A sealing plug 213 is provided in the oil inlet. The sealing plug 213 is used to seal the top end of the oil tank 210. A fixing block 211 is fixed to the upper side of one side of the oil tank 210. The side of the fixing block 211 near the fixing frame 4 is fixed to the surface of the fixing frame 4.

[0043] Open the sealing plug 213 on the top of the oil tank 210 and inject lubricating oil into the oil tank 210 through the oil inlet in the middle of the top of the oil tank 210. When the lubricating oil moves from the oil injection hole 218 on the top surface of one end of the clamping block 205 to the bottom end of the oil supply pipe 212 and completely overlaps with the bottom end of the oil supply pipe 212, the lubricating oil inside the oil tank 210 will enter the inner cavity of the clamping block 205 through the oil supply pipe 212, and then flow out from the oil injection hole 214 to the surface of the cleaning sponge 206. After the cleaning sponge 206 absorbs the lubricating oil, it lubricates the surface of the cutting blade 3 when the cutting blade 3 rotates.

[0044] The implementation principle of the paper-aluminum-plastic slitting device in this application embodiment is as follows: Before using the device, multiple cutting blades 3 are mounted on the rotating shaft 6 as required, and a corresponding number of cleaning and lubrication mechanisms 2 are mounted on the lower end of the fixed frame 4 near the cutting blades 3. The device is started so that the feeding roller 9 drives the paper-aluminum-plastic composite material to be conveyed, and the rotating shaft 6 rotates to drive the cutting blades 3 to cut the material. The screw 202 is moved by rotating the nut 203, and the transmission rod 207 is linked with the clamping block 205 to move the two cleaning sponges 206 close to the sides of the cutting blades 3. When the cutting blades 3 rotate, their surfaces are cleaned, and the cleaning sponges 206 are moved outward to deform and detach from the insert block 215. Then, a new cleaning sponge 206 is replaced. The lubricating oil flows through the oil supply pipe 212 and the second oil injection hole 218 to the inner cavity of the clamping block 205, and then flows from the first oil injection hole 214 to the surface of the cleaning sponge 206, lubricating the surface of the cutting blades 3 as they rotate.

[0045] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
