A slitting device for a slitting machine

Abstract

The utility model discloses a slitting device for a slitting machine, which relates to the technical field of slitting machines, and includes a housing, a bracket, a control component, a fixing component and a clamping component. When the device is working, the utility model controls the clamping component to clamp the blade by first adjusting the control component and the fixing component, and then starts the motor.

When it moves to a suitable position, the bidirectional screw stops rotating, and the slider is fixed by adjusting the fixing component, and then the blade is no longer clamped by adjusting the control component. At this time, the motor drives the bidirectional screw to rotate, which drives the blade to rotate. Thereby, the spacing between the blades can be adjusted more accurately, making the spacing between the blades convenient to adjust.

Description

Technical Field

[0001] The utility model relates to the technical field of slitting machines, in particular to a slitting device for slitting machines. Background Art

[0002] In the industries of sanitary paper, printing, newspaper, advertising, mobile phone protective film, etc., in most cases, the raw materials delivered by the raw material supplier are large in size, and the raw materials need to be cut into smaller sizes to meet the production and preparation requirements of the products. The slitting machine can be used to achieve the above requirements. The slitting machine is mainly composed of a feeding module and a slitting module. The slitting module is mainly used for cutting and transporting raw materials, and is mainly composed of a frame, a cutter component, and a traction roller group.

[0003] In traditional slitting machines, the cutter components and the frame are in a relatively fixed assembly state. When materials of different sizes or lengths need to be slit, this can only be achieved by adjusting the positional relationship between the cutters of the slitting machine. The procedure is relatively complicated and the adjustment accuracy is not high.

[0004] In the prior art, a Chinese patent with a publication number of CN217256584U is proposed to solve the above-mentioned technical problems. The technical solution disclosed in the patent document is as follows: a slitting device for a slitting machine, including a frame, a cutter component, and a traction roller group, characterized in that: a sliding mechanism is provided between the cutter component and the frame, the cutter component includes a cutter wall plate and a cutter bottom plate, the cutter wall plate is vertically fixedly installed on the end surface of the cutter bottom plate, and the cutter bottom plate is linked with the sliding mechanism; the sliding mechanism includes a transmission shaft, a first bevel gear, a second bevel gear, and a ball screw, the ball screw is threadedly connected with a screw seat, the screw seat is relatively fixedly connected with the cutter bottom plate, the cutter bottom plate is relatively fixedly installed with a slider, and the slider is linked with a slide rail fixedly installed on the frame. The beneficial effect of the utility model is: to provide a slitting device for a slitting machine, the positional relationship between the cutter component and the frame can be adjusted, and the slitting specifications are wider, but the device does not solve the problem of low precision and convenient adjustment of the slitting machine when adjusting. Summary of the invention

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

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

[0007] A slitting device for a slitting machine comprises a bracket and a rotating roller. A shell is fixedly connected to the top of the bracket, a motor is fixedly connected to one end of the shell, a slide groove is opened on the top of the shell, a bidirectional screw rod is rotatably connected inside the shell, one end of the bidirectional screw rod is fixedly connected to the output end of the motor, a plurality of sliders are arranged in the shell, the sliders are respectively slidably connected to the slide grooves, a blade is arranged inside the slider, the blade is threadedly connected to the bidirectional screw rod, the slider is rotatably connected to the blade, a clamping component for clamping the blade is connected inside the slider, a control component for controlling the operation of the clamping component is connected to the top of the slider, and a fixing component for fixing the position of the slider is connected to one side of the slider.

[0008] When the device is working, the clamping part can be controlled to clamp the blade by adjusting the control part and the fixing part first, and then the motor is started. At this time, the motor drives the bidirectional screw to rotate, and the rotation of the bidirectional screw will drive the blade connected with its thread to rotate. Because the blade is in a clamped state at this time, and the slider is slidably connected to the housing, when the bidirectional screw rotates, it can drive the slider to move along the length direction of the slide slot. When it moves to the appropriate position, the bidirectional screw stops rotating. At this time, the slider is fixed by adjusting the fixing part, and then the blade is no longer clamped by adjusting the control part. At this time, the motor drives the bidirectional screw to rotate, which will drive the blade to rotate. This makes it possible to adjust the spacing between the blades more accurately, making the spacing between the blades easy to adjust.

[0009] A further improvement of the technical solution of the utility model is that: the control component includes a push rod, a through hole is opened on the push rod, a card block is slidably connected in the through hole, the card blocks are symmetrically arranged, pressure springs are fixedly connected between the card blocks, a first card is fixedly connected in the slider, a second card is arranged below the first card, grooves are symmetrically opened in the slider, the second card is slidably connected to the groove, one end of the push rod is fixedly connected to a pressure plate, one side of the pressure plate is fixedly connected to an elastic spring, the other end of the elastic spring is fixedly connected to the slider, and the other end of the push rod is fixedly connected to a cone.

[0010] The above-mentioned technical scheme is adopted. In this scheme, when it is necessary to clamp the blade, the pressure plate is pressed downward. At this time, the pressure plate will drive the push rod to move downward, and the elastic spring is in a compressed state. At this time, the block is subjected to the pressure of the first clamping member, so that the block moves inward, thereby squeezing the pressure spring. When the block passes through the first clamping member, the block is no longer subjected to pressure, and the pressure spring pushes the block to move outward, thereby achieving the purpose of fixing the position of the push rod. When it is not necessary to clamp the blade, the pressure plate is continued to be pressed downward, so that the block passes through the second clamping member, and then the pressure plate is released. At this time, the elastic spring pushes the pressure plate to move in the opposite direction, and drives the second clamping member to move upward through the clamping member until the first clamping member conflicts with the second clamping member. At this time, the clamping block is squeezed and can smoothly pass through the first clamping block and the second clamping block, thereby returning to its original position.

[0011] A further improvement of the technical solution of the utility model is that the clamping component includes a support shaft, the support shaft is fixedly connected to the slider, the support shaft is symmetrically arranged, a clamping rod is rotatably connected to the support shaft, and the clamping rod is rotatably connected to the outside of the support shaft through a torsion spring.

[0012] The above-mentioned technical scheme is adopted. In this scheme, when the push rod moves downward and is stuck under the first clamp, the cone at one end of the push rod squeezes the clamping rod, causing the clamping rod to move to both sides. Because the clamping rod is rotatably connected to the support shaft, the other end of the clamping rod will be squeezed toward the middle until it contacts the blade and fixes the blade. When the motor drives the bidirectional screw rod to rotate, it will drive the slider to move. When the push rod returns to its original position, the cone no longer squeezes the clamping rod, and the clamping rod returns to its original position under the action of the torsion spring. At this time, the clamping rod no longer clamps the blade, and the motor drives the bidirectional screw rod to rotate, which will drive the blade to rotate together to achieve the cutting effect.

[0013] A further improvement of the technical solution of the utility model is that the fixing component includes a bolt, the bolt is threadedly connected to the slider, one end of the bolt is fixedly connected with a fixing block, one side of the bolt is provided with a rubber pad, and the rubber pad is rotatably connected to the bolt.

[0014] The above-mentioned technical scheme is adopted. In this scheme, when the clamping rod clamps the blade, the bolt is rotated so that the fixed block at one end of the bolt is not in contact with the shell, and the slider can be moved at this time. When the clamping rod does not clamp the blade, the bolt is twisted so that the fixed block is in contact with the shell. By arranging a rubber pad between the bolt and the shell, the bolt can be effectively protected, so that the wear of the bolt is reduced during operation. At the same time, the rubber pad can provide a certain friction force, increase the tightening force of the bolt, prevent the bolt from loosening in a vibration environment, and thus reduce fatigue damage of the bolt.

[0015] A further improvement of the technical solution of the utility model is that a stopper is fixedly connected to one side of the blade, the stoppers are symmetrically arranged, the stoppers are evenly arranged along the circumferential direction, and the width between adjacent stoppers is greater than the width of the clamping rod.

[0016] The above technical solution is adopted, in which a plurality of blocks are fixedly connected on both sides of the blade to increase the clamping performance of the clamping rod. The width between adjacent blocks is set to be greater than the width of the clamping rod to make it easier to clamp during the clamping process of the clamping rod, thereby improving the working efficiency of the device.

[0017] A further improvement of the technical solution of the utility model is that a rounded corner is arranged at one end of the clamping rod close to the top rod.

[0018] The above technical solution is adopted, in which the rounded corners are provided on the movement of the clamping rod to facilitate the ejector rod to smoothly push the clamping rod open, while also effectively reducing the wear between the clamping rod and the ejector rod.

[0019] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0020] 1. The utility model provides a slitting device for a slitting machine. When the clamping rod clamps the blade, the bolt is rotated so that the fixed block at one end of the bolt does not contact the shell, and the slider can be moved. When the clamping rod does not clamp the blade, the bolt is twisted so that the fixed block contacts the shell. The bolt can be effectively protected by arranging a rubber pad between the bolt and the shell, so that the wear of the bolt is reduced during operation. At the same time, the rubber pad can provide a certain friction force, increase the tightening force of the bolt, prevent the bolt from loosening in a vibration environment, and thus reduce fatigue damage of the bolt.

[0021] 2. The utility model provides a slitting device for a slitting machine. A plurality of blocks are fixedly connected on both sides of a blade to increase the clamping performance of a clamping rod. The width between adjacent blocks is set to be greater than the width of the clamping rod to make it easier to clamp during the clamping process of the clamping rod, thereby improving the working efficiency of the device.

[0022] 3. The utility model provides a slitting device for a slitting machine. The rounded corners are arranged on the movement of the clamping rod to facilitate the push rod to smoothly push the clamping rod open, and at the same time effectively reduce the wear between the clamping rod and the push rod.

DETAILED DESCRIPTION

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

[0032] Example 1

[0033] like Figure 1 , Figure 2 As shown, the utility model provides a slitting device for a slitting machine, including a bracket 1 and a rotating roller 2; the characteristics are: a shell 3 is fixedly connected to the top of the bracket 1, a motor 4 is fixedly connected to one end of the shell 3, a slide groove 5 is opened on the top of the shell 3, a bidirectional screw rod 6 is rotatably connected inside the shell 3, one end of the bidirectional screw rod 6 is fixedly connected to the output end of the motor 4, a plurality of sliders 8 are arranged in the shell 3, the sliders 8 are slidably connected to the slide groove 5 respectively, a blade 7 is arranged inside the slider 8, the blade 7 is threadedly connected to the bidirectional screw rod 6, the slider 8 is rotatably connected to the blade 7, a clamping component for clamping the blade 7 is connected inside the slider 8, a control component for controlling the operation of the clamping component is connected to the top of the slider 8, and a fixing component for fixing the position of the slider 8 is connected to one side of the slider 8.

[0034] In this embodiment, when the device is working, the clamping part can be controlled to clamp the blade 7 by adjusting the control part and the fixing part first, and then the motor 4 is started. At this time, the motor 4 drives the bidirectional screw rod 6 to rotate, and the rotation of the bidirectional screw rod 6 will drive the blade 7 connected with its thread to rotate. Because the blade 7 is in a clamped state at this time, and the slider 8 is slidably connected with the housing 3, when the bidirectional screw rod 6 rotates, it can drive the slider 8 to move along the length direction of the slide 5. When it moves to a suitable position, the bidirectional screw rod 6 stops rotating. At this time, the slider 8 is fixed by adjusting the fixing part, and then the blade 7 is no longer clamped by adjusting the control part. At this time, the motor 4 drives the bidirectional screw rod 6 to rotate, which drives the blade 7 to rotate. Thereby, the spacing between the blades 7 can be adjusted more accurately, making the spacing between the blades 7 convenient to adjust.

[0035] like Figure 5As shown, in the present embodiment, preferably, the control component includes a push rod 9, a through hole 10 is opened on the push rod 9, a clamping block 11 is slidably connected in the through hole 10, the clamping blocks 11 are symmetrically arranged, and pressure springs 12 are fixedly connected between the clamping blocks 11, a first clamping member 14 is fixedly connected in the slider 8, a second clamping member 15 is arranged below the first clamping member 14, grooves 16 are symmetrically opened in the slider 8, and the second clamping member 15 is slidably connected to the groove 16, one end of the push rod 9 is fixedly connected to a pressure plate 17, one side of the pressure plate 17 is fixedly connected to an elastic spring 13, the other end of the elastic spring 13 is fixedly connected to the slider 8, and the other end of the push rod 9 is fixedly connected to a cone 18.

[0036] When it is necessary to clamp the blade 7, the pressure plate 17 is pressed downward. At this time, the pressure plate 17 will drive the push rod 9 to move downward, and the elastic spring 13 is in a compressed state. At this time, the block 11 is subjected to the pressure of the first clamping member 14, so that the stopper 24 moves inward, thereby squeezing the pressure spring 12. When the block 11 passes the first clamping member 14, the stopper 24 is no longer subjected to pressure, and the pressure spring 12 pushes the block 11 to move outward, thereby achieving the purpose of fixing the position of the push rod 9. When it is not necessary to clamp the blade 7, the pressure plate 17 is continued to be pressed downward, so that the block 11 passes the second clamping member 15, and then the pressure plate 17 is released. At this time, the elastic spring 13 pushes the pressure plate 17 to move in the opposite direction, and drives the second clamping member 15 to move upward through the block 11 until the first clamping member 14 conflicts with the second clamping member 15. At this time, the block 11 is squeezed and can smoothly pass through the first clamping block 11 and the second clamping block 11, thereby returning to its original position.

[0037] like Figure 5 As shown, preferably, the clamping component includes a support shaft 19, the support shaft 19 is fixedly connected to the slider 8, the support shaft 19 is symmetrically arranged, and a clamping rod 20 is rotatably connected to the support shaft 19, and the clamping rod 20 is rotatably connected to the outside of the support shaft 19 through a torsion spring.

[0038] When the push rod 9 moves downward and is stuck under the first clamping member 14, the cone 18 at one end of the push rod 9 squeezes the clamping rod 20, causing the clamping rod 20 to move to both sides. Because the clamping rod 20 is rotatably connected to the support shaft 19, the other end of the clamping rod 20 will be squeezed toward the middle until it contacts the blade 7 and fixes the blade 7. When the motor 4 drives the bidirectional screw rod 6 to rotate, it will drive the slider 8 to move. When the push rod 9 returns to its original position, the cone 18 no longer squeezes the clamping rod 20, and the clamping rod 20 returns to its original position under the action of the torsion spring. At this time, the clamping rod 20 no longer clamps the blade 7, and the motor 4 drives the bidirectional screw rod 6 to rotate, which will drive the blade 7 to rotate together to achieve the cutting effect.

[0039] Example 2

[0040] like Figure 4 , Figure 6As shown, based on Example 1, the utility model provides a technical solution: preferably, the fixing component includes a bolt 21, the bolt 21 is threadedly connected to the slider 8, one end of the bolt 21 is fixedly connected with a fixing block 23, one side of the bolt 21 is provided with a rubber pad 22, and the rubber pad 22 is rotatably connected to the bolt 21.

[0041] In this embodiment, when the clamping rod 20 clamps the blade 7, the bolt 21 is rotated so that the fixing block 23 at one end of the bolt 21 is not in contact with the shell 3, and the slider 8 can be moved. When the clamping rod 20 does not clamp the blade 7, the bolt 21 is twisted so that the fixing block 23 is in contact with the shell 3. By arranging a rubber pad 22 between the bolt 21 and the shell 3, the bolt 21 can be effectively protected, so that the wear of the bolt 21 is reduced during operation. At the same time, the rubber pad 22 can provide a certain friction force, increase the tightening force of the bolt 21, and prevent the bolt 21 from loosening under a vibration environment, thereby reducing fatigue damage of the bolt 21.

[0042] Example 3

[0043] like Figure 3 As shown, based on Example 2, the utility model provides a technical solution: preferably, a stopper 24 is fixedly connected to one side of the blade 7, the stopper 24 is symmetrically arranged, the stopper 24 is evenly arranged along the circumferential direction, and the width between adjacent stoppers 24 is greater than the width of the clamping rod 20.

[0044] In this embodiment, a plurality of blocks 24 are fixedly connected on both sides of the blade 7 to increase the clamping performance of the clamping rod 20. The width between adjacent blocks 24 is set to be greater than the width of the clamping rod 20 to make it easier to clamp during the clamping process of the clamping rod 20, thereby improving the working efficiency of the device.

[0045] Example 4

[0046] like Figure 5 As shown, based on Example 3, the utility model provides a technical solution: preferably, a rounded corner 25 is provided at one end of the clamping rod 20 close to the push rod 9.

[0047] In this embodiment, the rounded corners 25 are provided at the movement of the clamping rod 20 to facilitate the push rod 9 to smoothly push the clamping rod 20 open, while also effectively reducing the wear between the clamping rod 20 and the push rod 9.

[0048] The working principle of the slitting device for this slitting machine is described in detail below.

[0049] like Figure 1-6As shown, when the device is working, the clamping part can be controlled to clamp the blade 7 by adjusting the control part and the fixing part first, and then the motor 4 is started. At this time, the motor 4 drives the bidirectional screw 6 to rotate, and the rotation of the bidirectional screw 6 will drive the blade 7 connected with its thread to rotate. Because the blade 7 is in a clamped state at this time, and the slider 8 is slidably connected with the housing 3, when the bidirectional screw 6 rotates, it can drive the slider 8 to move along the length direction of the slide 5. When it moves to a suitable position, the bidirectional screw 6 stops rotating. At this time, the slider 8 is fixed by adjusting the fixing part, and then the blade 7 is no longer clamped by adjusting the control part. At this time, the motor 4 drives the bidirectional screw 6 to rotate, which drives the blade 7 to rotate. Thereby, the spacing between the blades 7 can be adjusted more accurately, making the spacing between the blades 7 convenient to adjust. When it is necessary to clamp the blade 7, the pressure plate 17 is pressed downward. At this time, the pressure plate 17 will drive the push rod 9 to move downward, and the elastic spring 13 is in a compressed state. At this time, the block 11 is subjected to the pressure of the first clamping member 14, so that the stopper 24 moves inward, thereby squeezing the pressure spring 12. When the block 11 passes the first clamping member 14, the stopper 24 is no longer subjected to pressure, and the pressure spring 12 pushes the block 11 to move outward, thereby achieving the purpose of fixing the position of the push rod 9. When it is not necessary to clamp the blade 7, the pressure plate 17 is continued to be pressed downward, so that the block 11 passes the second clamping member 15, and then the pressure plate 17 is released. At this time, the elastic spring 13 pushes the pressure plate 17 to move in the opposite direction, and drives the second clamping member 15 to move upward through the block 11 until the first clamping member 14 conflicts with the second clamping member 15. At this time, the block 11 is squeezed and can smoothly pass through the first clamping block 11 and the second clamping block 11, thereby returning to its original position. When the push rod 9 moves downward and is stuck under the first clamping member 14, the cone 18 at one end of the push rod 9 squeezes the clamping rod 20, causing the clamping rod 20 to move to both sides. Because the clamping rod 20 is rotatably connected to the support shaft 19, the other end of the clamping rod 20 will be squeezed toward the middle until it contacts the blade 7 and fixes the blade 7. When the motor 4 drives the bidirectional screw rod 6 to rotate, it will drive the slider 8 to move. When the push rod 9 returns to its original position, the cone 18 no longer squeezes the clamping rod 20, and the clamping rod 20 returns to its original position under the action of the torsion spring. At this time, the clamping rod 20 no longer clamps the blade 7, and the motor 4 drives the bidirectional screw rod 6 to rotate, which will drive the blade 7 to rotate together to achieve the cutting effect. When the clamping rod 20 clamps the blade 7, the bolt 21 is rotated at this time so that the fixing block 23 at one end of the bolt 21 is not in contact with the shell 3, and the slider 8 can be moved at this time. When the clamping rod 20 does not clamp the blade 7, the bolt 21 is twisted at this time so that the fixing block 23 is in contact with the shell 3. By arranging a rubber pad 22 between the bolt 21 and the shell 3, the bolt 21 can be effectively protected, so that the wear of the bolt 21 is reduced during operation. At the same time, the rubber pad 22 can provide a certain friction force, increase the tightening force of the bolt 21, and prevent the bolt 21 from loosening under a vibration environment, thereby reducing fatigue damage of the bolt 21.A plurality of stoppers 24 are fixedly connected on both sides of the blade 7 to increase the clamping performance of the clamping rod 20. The width between adjacent stoppers 24 is greater than the width of the clamping rod 20 to make it easier to clamp during the clamping process of the clamping rod 20, thereby improving the working efficiency of the device. A rounded corner 25 is provided on the movement of the clamping rod 20 to facilitate the push rod 9 to smoothly push the clamping rod 20 open, while also effectively reducing the wear between the clamping rod 20 and the push rod 9.

[0050] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
