Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of slitting mechanisms, in particular to a clamping slitting structure for a small-disk paper slitting machine. Background Art
[0002] During the processing of paper towels, they are often wound into a paper roll, and then the paper roll is cut according to a certain thickness as required. Among them, during cutting, the existing cutting method is to arrange the paper roll horizontally, clamp the paper roll with a clamping mechanism, and then move the corresponding moving block, thereby driving the clamping mechanism and the paper roll to move synchronously and move the paper roll to the saw blade of the slitting machine for cutting.
[0003] Among them, in the existing method, since the moving blocks all move longitudinally during cutting, the cutting gap is small and the paper roll is thick, it is easy to cause the saw to get stuck due to the squeezing of the paper towels when cutting the paper towels, thereby affecting its normal operation. Utility Model Content
[0004] The utility model provides a clamping and slitting structure for a small-disk paper slitting machine, which is used to solve the defects in the prior art.
[0005] The utility model is realized through the following technical solutions:
[0006] The clamping and slitting structure used in the small-disk paper slitting machine includes a first moving block and a second moving block that move synchronously, and a clamping mechanism is arranged on the first moving block and the second moving block, and a saw blade is arranged between the first moving block and the second moving block, and a longitudinal first slide rail and a second slide rail are respectively arranged below the first moving block and the second moving block, and the first slide rail is slidably matched with a support plate, and a transverse slide rail is fixedly connected to the top surface of the support plate in the horizontal direction, and a transverse slider is matched on the transverse slide rail, and the top surface of the transverse slider is fixedly connected to the longitudinal plate, and the left side surface of the longitudinal plate is an inclined surface inclined from front to rear and to the right, and the first moving block is fixedly connected to the top surface of the longitudinal plate, and a limiting rod in contact with the inclined surface is fixedly arranged on the left side of the longitudinal plate, and the second slide rail slide is matched with a longitudinal slider fixedly connected to the second moving block, and the transverse slide rail is vertically connected to a baffle upward, and the baffle and the longitudinal plate are fixedly connected via a spring.
[0007] When the present application is in use, the clamping mechanism clamps the two sides of the paper roll, and then drives the paper roll to move from back to front and pass through the saw blade, wherein, when the first moving block and the second moving block move forward, the second moving block moves forward normally and along the longitudinal line, and when the first moving block moves forward, it drives the longitudinal plate to move synchronously, because the longitudinal plate slides with the transverse slide rail through the transverse sliding block, the left side of the longitudinal plate is an inclined surface inclined from front to back and to the right, the limit rod contacts the inclined surface, and the right side of the longitudinal plate is fixedly connected to the baffle by a spring. Therefore, when moving forward, the longitudinal plate will move to the left under the action of the spring, thereby driving the first moving block to move to the left, so that the distance between the first moving block and the second moving block becomes larger, thereby making the paper roll open when cutting, thereby reducing the occurrence of saw jamming and ensuring its normal use. After cutting is completed, the first moving block and the second moving block move backward, and under the blocking of the limit rod, the first moving block moves in the direction close to the second moving block.
[0008] Preferably, the clamping mechanism comprises a slideway vertically fixedly arranged on the corresponding first moving block and the second moving block, the slideway is matched with a slide plate, the slide plate is fixedly connected with a clamping plate, a telescopic cylinder is arranged above the clamping plate, the fixed end of the telescopic cylinder is fixedly connected with the corresponding first moving block and the second moving block, and the movable end of the telescopic cylinder is fixedly connected with the corresponding clamping plate. The telescopic cylinder drives the clamping plate to move downward, so that the paper roll is compressed, thereby realizing clamping.
[0009] Preferably, the second slider is fixedly connected with a fixed plate, the fixed plate is transversely provided with a slide groove, the first slider is fixedly connected with a round rod, the round rod passes through the fixed plate and is fixedly connected with a blocking plate, the blocking plate has a diameter greater than the width of the slide groove, and the longitudinal length of the round rod is consistent with the thickness of the fixed plate. By setting the fixed plate, the first moving block and the second moving block can be synchronously moved and the first moving block can be ensured to approach the second moving block.
[0010] Preferably, a U-shaped groove is opened to the left at the right end of the limit rod, and a roller is arranged in the U-shaped groove. A rotating shaft is vertically connected to the center of both sides of the roller. The rotating shaft is rotatably connected to the inner wall of the U-shaped groove through a bearing, and the outer side of the roller contacts the inclined surface. The roller can replace the sliding friction between the limit rod and the inclined surface with rolling friction, thereby reducing the friction force and making the longitudinal plate move more smoothly.
[0011] The beneficial effect of the utility model is that the use of the present application can ensure that the first moving block and the second moving block move longitudinally while the first moving block is away from or close to the second moving block, so that the paper roll can be cut and opened at the same time, thereby reducing the occurrence of saw jamming and ensuring its normal use.

Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] The clamping and slitting structure used in small paper slitting machines, such as Figure 1-3As shown. It includes a first moving block 1 and a second moving block 2 that move synchronously, the first moving block 1 and the second moving block 2 are both provided with a clamping mechanism, a saw blade 3 is arranged between the first moving block 1 and the second moving block 2, and a longitudinal first slide rail 4 and a second slide rail 5 are respectively arranged below the first moving block 1 and the second moving block 2, the first slide rail 4 is slidably matched with a support plate 6, a transverse slide rail 7 is transversely fixedly connected to the top surface of the support plate 6, a transverse slide rail 7 is matched with a transverse slider, a longitudinal plate 8 is fixedly connected to the top surface of the transverse slider, the left side surface of the longitudinal plate 8 is an inclined surface inclined from front to back and right, the first moving block 1 is fixedly connected to the top surface of the longitudinal plate 8, a limiting rod 9 in contact with the inclined surface is fixedly arranged on the left side of the longitudinal plate 8, the second slide rail 5 slideway is matched with a longitudinal slider 10 fixedly connected to the second moving block 2, the transverse slide rail 7 is vertically connected to a baffle 11 upward, and the baffle 11 is fixedly connected to the longitudinal plate 8 via a spring 12.
[0020] The clamping mechanism includes a slideway vertically fixedly arranged on the corresponding first moving block 1 and the second moving block 2, the slideway is matched with a slide plate, the slide plate is fixedly connected with a clamping plate 14, a telescopic cylinder 13 is provided above the clamping plate 14, the fixed end of the telescopic cylinder 13 is fixedly connected with the corresponding first moving block 1 and the second moving block 2, and the movable end of the telescopic cylinder 13 is fixedly connected with the corresponding clamping plate 14.
[0021] When the present application is in use, the clamping mechanism is first started, wherein the telescopic cylinder 13 drives the pressure plate to move downward, thereby pressing the paper roll tightly to achieve clamping of the paper roll. When the first moving block 1 and the second moving block 2 are moved forward, the paper roll moves from the back to the front and passes through the saw blade 3. When the first moving block 1 and the second moving block 2 move forward, the second moving block 2 moves forward normally and along the longitudinal line. When the first moving block 1 moves forward, it drives the longitudinal plate 8 to move synchronously. Since the longitudinal plate 8 slides with the transverse slide rail 7 through the transverse slider, the left side of the longitudinal plate 8 is an inclined surface inclined from front to back and to the right, and the limit rod 9 contacts the inclined surface. The right side of the longitudinal plate 8 is fixedly connected to the baffle 11 by a spring 12. Therefore, when moving forward, the longitudinal plate 8 will move to the left under the action of the spring 12, thereby driving the first moving block 1 to move to the left, so that the distance between the first moving block 1 and the second moving block 2 becomes larger, thereby making the opening diameter of the paper roll larger when cutting, thereby reducing the occurrence of saw jamming and ensuring its normal use. After cutting is completed, the first moving block 1 and the second moving block 2 move backward. Under the blocking of the limit rod 9, the first moving block 1 moves toward the direction close to the second moving block 2.
[0022] The second slider is fixedly connected with a fixing plate 15, which is transversely provided with a slide groove 16. The first slider is fixedly connected with a round rod, which passes through the fixing plate 15 and is fixedly connected with a blocking plate 11. The diameter of the blocking plate 11 is larger than the width of the slide groove 16, and the longitudinal length of the round rod is consistent with the thickness of the fixing plate 15. By setting the fixing plate 15, the first moving block 1 and the second moving block 2 can be synchronously moved and the first moving block 1 can be ensured to approach the second moving block 2.
[0023] A U-shaped groove is formed on the right end of the limit rod 9 to the left, and a roller 17 is arranged in the U-shaped groove. A rotating shaft is vertically connected to the center of both sides of the roller 17. The rotating shaft is rotatably connected to the inner wall of the U-shaped groove through a bearing, and the outer side of the roller 17 contacts the inclined surface. The roller 17 can replace the sliding friction between the limit rod 9 and the inclined surface with rolling friction, thereby reducing the friction force and making the longitudinal plate 8 move more smoothly.
[0024] The use of the present application can ensure that the first moving block 1 and the second moving block 2 move longitudinally while the first moving block 1 is away from or close to the second moving block 2, so that the paper roll can be cut and opened at the same time, thereby reducing the occurrence of saw jamming and ensuring its normal use.
