Description

Technical Field

[0001] This utility model relates to the field of slitting machine technology, specifically to an adjustment device for slitting machine cutting. Background Technology

[0002] In paper slitting machines, the rollers that squeeze the paper are a key component. These rollers are typically designed to precisely control the feeding and positioning of the paper and to provide the necessary pressure during the slitting process to ensure the accuracy of the cut and the flatness of the paper.

[0003] CN206529107U discloses an adjustable paper slitting machine, including a feeding roller, a drive motor, and pulleys. The feeding roller has a telescopic support rod connected internally, and the telescopic support rod is connected to the drive motor via the pulleys. A tension roller is located on the right side of the monitoring device, and an air pump is connected to the air inlet below the tension roller. The cutter wheel is connected to the support frame via a lead screw, and a paper roll is located on its right side. A discharge port is located below the pressure nozzle. This adjustable paper slitting machine innovatively combines the design of commonly used adjustable paper slitting machines. By incorporating double tension rollers and a pressure roller inside the device, the paper receives sufficient traction and flatness before entering the slitting device, ensuring the quality of the finished product. Furthermore, the machine accelerates production speed and improves efficiency by setting up a rotating platform with multiple paper rolls installed below it. However, this patent still has the following problems in practical use:

[0004] In the process of paper feeding, existing slitting machines not only need to keep the paper taut, but also need to squeeze and clamp the paper to prevent it from shifting. Especially when pulp paper is converted from large sheets to small sheets, independent pairs of rollers are needed to squeeze the small paper strips to prevent them from shifting during the winding process. However, because the paper feeding angle is not fixed, a certain section of paper may not be able to contact the lifting roller and the roller at the same time. As a result, the pairs of rollers of the same height cannot squeeze the paper onto the lifting roller at the same time, resulting in poor anti-deviation effect during transportation.

[0005] An adjustment device for slitting machine cutting is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide an adjustment device for slitting machines, in order to solve the problem mentioned in the background art that existing slitting machines, during the paper feeding process, not only need to tighten the paper, but also need to squeeze and clamp the paper to prevent it from shifting. Especially when pulp paper is converted from large sheets to small sheets, independent pairs of rollers are needed to squeeze the small paper strips to prevent them from shifting during the winding process. However, since the paper feeding angle is not fixed, a certain section of paper may not be able to contact the lifting roller and the roller at the same time, which leads to the problem that the pairs of rollers of the same height cannot squeeze the paper onto the lifting roller at the same time.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an adjustment device for cutting a slitting machine, comprising a slitting machine body, the slitting machine body comprising a machine base, a pair of mounting plates fixedly connected to one side of the machine base, a cross column provided between the two mounting plates, a movable sleeve slidably fitted on the outside of the cross column, and a plurality of lifting rollers rotatably mounted on one side of the machine base.

[0008] An adjustment assembly is provided on the outer side of the movable sleeve. The adjustment assembly includes a first side plate and a second side plate symmetrically fixed to the outer side of the movable sleeve. A rotating block is rotatably connected to the first side plate. A threaded column is rotatably connected to the rotating block. A first threaded sleeve is threadedly slidably connected to the outer side of the threaded column. A movable column is fixedly connected to the outer side of the first threaded sleeve. A limit plate is fixedly connected to the end of the movable column.

[0009] The second side plate is rotatably connected to a rotating plate, the rotating plate has a groove in the middle, and a pressure roller is rotatably connected to the bottom end of the rotating plate.

[0010] The mounting plate has a central groove on its inner side, and a threaded rod is rotatably installed inside the central groove. The threaded rod is slidably connected to a second threaded sleeve by its external thread, and the second threaded sleeve is fixedly connected to the cross column.

[0011] Preferably, a first motor is fixedly connected to the top of the mounting plate, and the output end of the first motor extends into the mounting plate and is fixedly connected to the threaded rod.

[0012] Preferably, the first side plate is fixedly connected to the bottom outer side of the movable sleeve, and the top of the second side plate is fixedly connected to the top outer side of the movable sleeve.

[0013] Preferably, the groove is slidably connected to the movable column.

[0014] Preferably, the top of the movable sleeve is provided with a limiting component, the limiting component includes vertical plates symmetrically fixedly connected to the top of the movable sleeve, a locking strip fixedly connected to the top of the horizontal column, a connecting shaft rotatably connected between the two vertical plates, a round block fixedly connected to the outside of the connecting shaft, and a crank handle fixedly connected to the outside of the round block.

[0015] Preferably, a lifting block is vertically slidably connected to the top of the movable sleeve, a sliding pad is slidably connected to the top of the lifting block, and a locking block is fixedly connected to the bottom of the lifting block, the locking block engaging with the locking strip.

[0016] Preferably, the connecting shaft is fixedly connected to the non-center part of the circular block.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This adjusting device for slitting machine cutting can lower and squeeze the paper by lowering the height of the pressure roller, pressing the paper onto the support roller for initial positioning. Then, by rotating the threaded column connected to another pressure roller, the other pressure roller can also be lowered, fully squeezing the paper into contact with the support roller. Ultimately, the pressure roller can stably squeeze the paper, reducing the possibility of paper deviation. The specific details are as follows:

[0018] 1. The first motor rotates the threaded rod, which in turn causes the second threaded sleeve to move the cross column vertically. This lowers the height of the pressure roller and squeezes the paper, pressing it onto the support roller for initial positioning. When the paper is tilted and only one pressure roller is pressing it down, the threaded column connected to the other pressure roller is rotated, causing the first threaded sleeve to move along the threaded column. This allows the moving column to slide within the groove while the rotating plate rotates downwards, causing the other pressure roller to also descend. This fully squeezes the paper into contact with the support roller, ultimately ensuring that the pressure roller can stably press the paper down and reducing the possibility of paper deviation.

[0019] 2. The crank handle causes the circular block to rotate, which in turn reduces the pressure of the circular block on the sliding pad and releases it from contact. At this time, the sliding pad slides with the lifting block, which lifts the sliding pad and causes the lifting block to move upward, causing the locking block to disengage from the locking strip. Finally, the first side plate can drive the pressure roller to quickly change position along the horizontal column, so that the pressure roller can stably press the paper cut into strips. When the paper width changes, adaptive adjustments are made. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 - Figure 5 The present invention provides a technical solution: an adjustment device for cutting a slitting machine, comprising a slitting machine body, the slitting machine body comprising a machine base, a pair of mounting plates 1 fixedly connected to one side of the machine base, a horizontal column 101 provided between the two mounting plates 1, a movable sleeve 102 slidably sleeved on the outside of the horizontal column 101, and a plurality of lifting rollers rotatably mounted on one side of the machine base.

[0028] An adjustment component 2 is provided on the outer side of the movable sleeve 102. The adjustment component 2 includes a first side plate 201 and a second side plate 202 symmetrically fixed to the outer side of the movable sleeve 102. The first side plate 201 is rotatably connected to a rotating block 203. The rotating block 203 is rotatably connected to a threaded post 204. The outer side of the threaded post 204 is threadedly slidably connected to a first threaded sleeve 205. The outer side of the first threaded sleeve 205 is fixedly connected to a movable post 206. The end of the movable post 206 is fixedly connected to a limiting piece 207. The limiting piece 207 fits against the side of the rotating plate 208, which can increase the stability of the movable post 206 when it moves.

[0029] The second side plate 202 is rotatably connected to a rotating plate 208. A groove 209 is provided in the middle of the rotating plate 208. A pressure roller 210 is rotatably connected to the bottom end of the rotating plate 208. The lifting roller is located below the pressure roller 210.

[0030] The mounting plate 1 has a central groove 212 on its inner side. A threaded rod 213 is rotatably mounted inside the central groove 212. A second threaded sleeve 214 is slidably connected to the outer thread of the threaded rod 213. The second threaded sleeve 214 is fixedly connected to the cross column 101.

[0031] A first motor 211 is fixedly connected to the top of the mounting plate 1. The output end of the first motor 211 extends into the mounting plate 1 and is fixedly connected to the threaded rod 213. The first side plate 201 is fixedly connected to the bottom outer side of the movable sleeve 102, and the top of the second side plate 202 is fixedly connected to the top outer side of the movable sleeve 102. The slide groove 209 is slidably connected to the movable column 206. The first motor 211 is a servo motor, and the two threaded rods 213 are of the same specification.

[0032] The top of the movable sleeve 102 is provided with a limiting component 3. The limiting component 3 includes vertical plates 302 that are symmetrically fixedly connected to the top of the movable sleeve 102, a locking strip 301 that is fixedly connected to the top of the horizontal column 101, a connecting shaft 303 that is rotatably connected between the two vertical plates 302, a round block 304 that is fixedly connected to the outside of the connecting shaft 303, and a crank 305 that is fixedly connected to the outside of the round block 304.

[0033] The top of the movable sleeve 102 is vertically slidably connected to a lifting block 307. The top of the lifting block 307 is slidably connected to a sliding pad 306. The bottom of the lifting block 307 is fixedly connected to a locking block 308. The locking block 308 is engaged with the locking strip 301. The sliding pad 306 and the lifting block 307 are connected by a stepped groove, so that the sliding pad 306 and the lifting block 307 cannot be separated. At the same time, the sliding pad 306 can be lifted, thereby driving the lifting block 307 to move upward.

[0034] The connecting shaft 303 is fixedly connected to the non-center part of the circular block 304; the connection between the connecting shaft 303 and the non-center part of the circular block 304 causes the rotation of the circular block 304 to change its distance from the sliding pad 306, thereby changing the sliding pad 306.

[0035] Working principle: Before using this type of slitting machine adjustment device, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 5As shown, the first motor 211 is started to rotate the threaded rod 213, which causes the second threaded sleeve 214 to drive the horizontal column 101 to move vertically. This allows the pressure roller 210 to be lowered and squeeze the paper, pressing the paper onto the lifting roller. When the paper is tilted and only one pressure roller 210 is pressing the paper, the threaded column 204 connected to the other pressure roller 210 is rotated, causing the first threaded sleeve 205 to move along the threaded column 204. This allows the moving column 206 to slide in the groove 209 while the rotating plate 208 rotates downward, allowing the other pressure roller 210 to also descend, fully squeezing the paper into contact with the lifting roller. Ultimately, the pressure roller 210 can stably squeeze the paper, reducing the possibility of paper deviation.

[0036] Shaking the handle 305 causes the circular block 304 to rotate the connecting shaft 303, thereby reducing the pressure of the circular block 304 on the sliding pad 306 and releasing the contact. At this time, the sliding pad 306 slides with the lifting block 307, thereby lifting the sliding pad 306 and causing the lifting block 307 to move upward, causing the locking block 308 to disengage from the locking strip 301. Finally, the first side plate 201 can drive the pressure roller 210 to quickly change position along the direction of the horizontal column 101, so that the pressure roller 210 can stably press the paper cut into strips. When the paper width changes, adaptive adjustment is made.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
