[0002] The sponge cutting device is a commonly used equipment in the sponge production process. After the foaming, the sponge is generally cut into the required size on the cutting machine according to the needs of use. Because the sponge has a porous honeycomb structure, it has excellent softness, elasticity, water absorption and water resistance, so it is often used as a sealing strip.

[0003] For example, patent number CN208841500U discloses an automatic cutting device suitable for sponge sealing strips, which includes a workbench, a conveyor belt is installed on the upper surface of the workbench, a cutting box is installed on one side of the workbench, an inspection window is installed on the front surface of the cutting box, a debris collection box is installed on the rear surface of the cutting box, a discharge plate is installed on the side of the cutting box away from the conveyor belt, and a cutting box is fixedly installed on the top of the inner part of the cutting box. The servo motor of the utility model can drive the driving rod to rotate. When the device cuts the sponge strip, it fixes one side of the sponge strip and then cuts it, which will cause the sponge strip on one side to deform and displace during the cutting process, and the fixing effect of the sponge strip is poor. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides an automatic cutting device suitable for sponge sealing strips, so as to solve the problem in the prior art that sponge strips of various models and sizes cannot be conveniently fixed and limited, resulting in poor cutting effect.

[0005] A automatic cutting device suitable for sponge sealing strips comprises a workbench and a first movable plate, characterized in that: a conveyor belt is arranged on the top of the workbench, a movable groove is opened on the inner wall of the first movable plate, a first motor is fixedly connected to the top outer wall of the first movable plate, a rotating column is fixedly connected to the output end of the first motor, a second contraction bin is arranged on the inner wall of the rotating column, movable blocks are symmetrically and movably connected to the inner walls of the movable groove on both sides, a plurality of first balls are rotatably connected to the bottom inner walls of the two movable blocks, a first clamping plate is fixedly connected to the bottom outer walls of the two movable blocks, a plurality of telescopic springs are fixedly connected to the inner walls of the two first clamping plates, and one end of the plurality of telescopic springs is commonly fixedly connected to the second clamping plate.

The inner walls on both sides of the first movable plate are provided with first contraction bins, and the inner walls of the first contraction bin and the second contraction bin are provided with spring wires. One end of the spring wires is fixedly connected to the movable block. When the sponge strip needs to be clamped, the rotating column can contract the spring wires, so that the two first clamping plates clamp the sponge strip. When clamping is not needed, the first motor is reversed, and the spring wire on the other side is recovered by the first contraction bin, thereby moving the two first clamping plates in opposite directions.

[0008] Through the arrangement of the above-mentioned structure, shaking and deformation can be prevented during the cutting process of the sponge strip, and the cutting effect is good. When the heights of the sponge strips to be cut are different, the operator starts the second motor to rotate the lifting column. When the lifting column rotates, it will lift and lower the lifting block on its outer wall and the first movable plate. When it is lifted to the appropriate position, the operator puts the sponge strip under the first movable plate to fix the height of the sponge strip.

[0009] Preferably, a plurality of second balls are rotatably connected to the inner wall of the bottom of the second clamping plate, and the plurality of second balls are in contact with the conveyor belt.

[0013] Preferably, a discharge plate is fixedly connected to one side outer wall of the cutting box.

[0014] By setting the discharging plate, the cut sponge strips can be easily discharged.

[0015] Preferably, first contraction bins are provided on both inner walls of the first movable plate, and spring wires are provided on the inner walls of the first contraction bin and the second contraction bin, and one end of the spring wires is fixedly connected to the movable block.

[0016] Through the setting of the above structure, when the sponge strip needs to be clamped, the rotating column can contract the spring wire, so that the two first clamping plates clamp the sponge strip. When clamping is not needed, the first motor is reversed, and the spring wire on the other side is recovered by the first contraction bin, thereby moving the two first clamping plates in opposite directions.

[0019] 2. The utility model starts the second motor to rotate the lifting column, thereby lifting the lifting block threadedly connected to the outer wall thereof, thereby lifting the first movable plate. When the heights of the sponge strips are different, the height of the first movable plate can be easily adjusted to better fix the sponge strips, thereby preventing the sponge strips from being displaced when being cut, resulting in a poor cutting effect.

[0027] The following is a further detailed description of the implementation of the present utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0028] As attached Figure 1 To Attachment Figure 5 As shown:

[0029] Embodiment 1: It includes a workbench 1 and a first movable plate 3, a conveyor belt 2 is provided on the top of the workbench 1, a movable groove 4 is opened on the inner wall of the first movable plate 3, a first motor 5 is fixedly connected to the top outer wall of the first movable plate 3, a rotating column 6 is fixedly connected to the output end of the first motor 5, a second contraction bin 601 is provided on the inner wall of the rotating column 6, movable blocks 7 are symmetrically and movably connected to the inner walls of the movable groove 4 on both sides, a plurality of first balls 701 are rotatably connected to the bottom inner walls of the two movable blocks 7, a first clamping plate 8 is fixedly connected to the bottom outer walls of the two movable blocks 7, a plurality of telescopic springs 9 are fixedly connected to the inner walls of the two first clamping plates 8, and a second clamping plate 10 is fixedly connected to one end of the plurality of telescopic springs 9.

[0030] The bottom inner wall of the second card plate 10 is rotatably connected with a plurality of second balls 101, and the plurality of second balls 101 are in contact with the conveyor belt 2. Through the arrangement of the second balls 101, the friction of the second card plate 10 can be reduced when the conveyor belt 2 is working, thereby preventing the device from being damaged.

[0031] The inner walls on both sides of the first movable plate 3 are provided with first contraction bins 301, and the inner walls of the first contraction bin 301 and the second contraction bin 601 are provided with spring wires 302, and one end of the spring wires 302 is fixedly connected to the movable block 7. When the sponge strip needs to be clamped, the rotating column 6 can contract the spring wires 302, so that the two first clamping plates 8 clamp the sponge strip. When clamping is not needed, the first motor 5 is reversed, and the spring wire 302 on the other side is recovered by the first contraction bin 301, thereby moving the two first clamping plates 8 in opposite directions. Through the arrangement of the above structure, sponge strips of various sizes can be conveniently fixed and clamped.

[0032] As can be seen from the above, when the sponge strip that needs to be cut is placed on the conveyor belt 2, the operator first centers the sponge strip and then starts the first motor 5. The started first motor 5 will drive the rotating column 6 to rotate and rotate and recycle the spring wire 302 on the outside of the first clamping plate 8. When the spring wire 302 is retracted, it will drive the two movable blocks 7 to move in the movable groove 4. The two movable blocks 7 will limit the sponge strips of different sizes. When the height of the first movable plate 3 changes, the telescopic spring 9 inside the first clamping plate 8 will drive the second clamping plate 10 to adaptively retract, thereby bidirectionally clamping sponge strips of various heights. Through the setting of the above structure, the sponge strip can be limited and fixed when it is cut to prevent the sponge strip from moving during the cutting process, resulting in poor cutting effect.

[0033] Embodiment 2: A plurality of fixed blocks 11 are fixedly connected to the top outer wall of the workbench 1, motor fixing plates 12 are fixedly connected to both sides of the outer walls of the plurality of fixed blocks 11, a second motor 13 is fixedly connected to the top outer walls of the plurality of motor fixing plates 12, a lifting column 14 is fixedly connected to the output ends of the plurality of second motors 13, a lifting card block 15 is fixedly connected to both side outer walls of the first movable plate 3, and the bottom ends of the plurality of lifting columns 14 are engaged with the bottom ends of the lifting card blocks 15.

[0034] A cutting box 16 is fixedly connected to one side of the workbench 1, and an observation window 17 is provided on one outer wall of the cutting box 16. The setting of the cutting box 16 can facilitate cutting of the sponge strips, and the setting of the observation window 17 can facilitate the operator to observe the inside of the machine during operation.

[0035] A discharge plate 18 is fixedly connected to an outer wall of one side of the cutting box 16. Through the arrangement of the discharge plate 18, the cut sponge strips can be conveniently discharged.

[0036] As can be seen from the above, when the heights of the sponge strips to be cut are different, the operator starts the second motor 13 to rotate the lifting column 14. When the lifting column 14 rotates, it will lift and lower the lifting block 15 on its outer wall and the first movable plate 3. When it is lifted to a suitable position, the operator places the sponge strip under the first movable plate 3 to fix the height of the sponge strip, thereby preventing the sponge strip from shaking and deforming during the cutting process, and achieving a good cutting effect.

[0037] Working principle: the operator first determines the length, width and height of the sponge bar, and then starts the first motor 5, causing the rotating column 6 fixedly connected to its output end to rotate, so as to recycle the spring line 302 on one side. When the spring line 302 is retracted, the two first clamping plates 8 will also move accordingly. The two first clamping plates 8 cooperate with each other to fix the sponge bar. At this time, the second motor 13 is started again, causing the lifting rotating column 14 fixedly connected to its output end to rotate, so as to lift and lower the first movable plate 3. During the lifting process, the telescopic spring 9 on the inner wall of the first clamping plate 8 will cause the second clamping plate 10 to adaptively retract, so as to facilitate the clamping of the sponge bar. After the height of the moving plate 3 is determined, the operator places the sponge strip to be cut on the conveyor belt 2, and then starts the conveyor belt 2. When the conveyor belt 2 starts, the second clamping plate 10 will generate friction with the conveyor belt 2. At this time, the second ball 101 will reduce the friction and move the sponge strip to the inside of the cutting box 16, so that the sponge strip can be fixed when it is cut to prevent the sponge strip from being displaced due to lack of fixation. The cut sponge strip is output from the discharge plate 18, and the operator collects the cut sponge strip. The setting of the observation window 17 can facilitate the operator to observe the inside of the device during operation.
