[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] like Figures 1 to 10 As shown, the present invention provides a paper tube processing unwinding device with a shock-absorbing effect, comprising a base 1 and further comprising:

[0037] Crossbar 2, crossbar 2 is fixedly connected to the outer wall of base 1, and the inner wall of crossbar 2 is provided with moving block 6 through electric slide rail 7;

[0038] The shock absorbing mechanism 3 is arranged outside the cross bar 2 and the base 1;

[0039] A placement roller 4, the outer wall of which is rotatably connected to a placement block 8, and the inner wall of which is provided with a fixing mechanism 5;

[0040] The shock absorbing mechanism 3 includes a slide bar 308 , and a support block 309 is provided on the outer wall of the slide bar 308 through a buffer module;

[0041] The fixing mechanism 5 includes a stopper 501 , and an outer wall of the stopper 501 is hingedly connected to a control block 504 via a rotating rod 503 .

[0042] Adopt the above scheme: base 1 is used to place paper rolls for paper tube processing, which can be placed on the ground. The paper rolls can be placed on the placement rollers 4 and fixed by the fixing mechanism 5. Figure 1As shown, the placing block 8 is then placed in the moving block 6. In the initial state, the moving block 6 is on the left side. As Figure 7 shown, when it is necessary to pull out the paper roll for paper tube processing, the electric slide rail 7 can be used to drive the moving block 6 to move to the right side. As Figure 4 shown, the starting end of the paper roll is fixed on the rotating wheel of the base 1, and the paper roll is pulled open by the rotation of the rotating wheel for conveying to make a paper tube. The shock absorption mechanism 3 can drive the support block 309 to turn downward and contact the ground when the moving block 6 moves, improving stability, thus achieving a shock absorption effect, so as to prevent the base 1 from shaking due to equipment operation during the processing and affecting the conveying of the paper roll.

[0043] As Figure 3 、 Figure 4 and Figure 6 、 Figure 7 shown, a connecting block 301 is fixedly connected to the outer wall of the bottom end of the moving block 6, a fixed rod A303 is fixedly connected to the outer wall of the base 1, a moving rod A302 is slidably connected to the inner wall of the fixed rod A303, a fixed rod B305 is fixedly connected to the outer wall of the base 1, a moving rod B307 is elastically connected to the inner wall of the fixed rod B305 through a return spring 306, and a hydraulic oil pipe 304 is fixedly connected to the outer walls of the fixed rod A303 and the fixed rod B305.

[0044] Adopting the above scheme: The connecting block 301 penetrates through the outer wall of the bottom end of the cross bar 2. When the electric slide rail 7 drives the moving block 6 to move, the connecting block 301 can move synchronously therewith and drive the moving rod A302 to move in the inner wall of the fixed rod A303. The fixed rod A303, the fixed rod B305 and the hydraulic oil pipe 304 are connected and communicated, and there is hydraulic oil in all three of them. When the moving block 6 is on the left side in the normal state, the state of the moving rod A302 and the fixed rod A303 is as Figure 7 shown. Due to the elastic force, the return spring 306 makes the moving rod B307 move upward into the inner wall of the fixed rod B305, squeezing the hydraulic oil in the fixed rod B305 so that it flows into the fixed rod A303. When the moving block 6 moves to the right side, the moving rod A302 will squeeze the hydraulic oil in the fixed rod A303 so that it flows from the hydraulic oil pipe 304 into the fixed rod B305, and under the pressure, it pushes the moving rod B307 to move downward, stretching the return spring 306, driving the slide rod 308 to move downward synchronously, unfolding the buffer module and the support block 309, and the support block 309 contacts the ground, then the support effect can be achieved. And because there are multiple groups of buffer modules and support blocks 309 symmetrically arranged, the base 1 can be prevented from shaking during operation, and the buffer module can also provide a certain buffer effect. Since the position of the moving block 6 is fixed, the hydraulic oil always generates pressure on the moving rod B307, ensuring that the buffer module and the support block 309 remain unfolded, reducing the vibration generated by the base 1 during operation.

[0045] As Figure 3 、Figure 4 and Figure 6 、 Figure 7 As shown, the connecting block 301 is slidably connected to the inner wall of the cross bar 2, the hydraulic oil pipe 304 is fixedly connected in the inner wall of the cross bar 2, the moving rod B 307 is fixedly connected to the outer wall of the sliding rod 308, the sliding rod 308 is slidably connected to the outer wall of the base 1, and the placing block 8 is in contact with the inner wall of the moving block 6; one end of the return spring 306 is fixedly connected to the outer wall of the moving rod B 307, the other end of the return spring 306 is fixedly connected to the inner wall of the fixed rod B 305, and the support block 309 is hinged to the outer wall of the base 1.

[0046] Adopting the above solution: The sliding rod 308 can only move up and down on the outer wall of the base 1. When the hydraulic oil pushes the moving rod B 307 to move downward, the sliding rod 308 moves downward and drives the buffer module to flip. The buffer module can drive the support block 309 to flip downward and contact the ground; during the process of the moving block 6 moving to the left, the connecting block 301 moves synchronously with the moving rod A 302, and the hydraulic oil gradually loses the force squeezed by the moving rod A 302. Then, the elastic force of the return spring 306 can be used to move the moving rod B 307 upward to reset, drive the sliding rod 308 to move upward, flip and retract the buffer module and the support block 309, as Figure 7 shown, at this time the hydraulic oil is inside the fixed rod A 303.

[0047] As Figure 4 、 Figure 5 shown, the buffer module includes a hinge rod A 31. A groove 33 is formed in the inner wall of the hinge rod A 31. A rubber pad 35 is elastically connected to the inner wall of the hinge rod A 31 through a buffer spring 32. An outer wall of the rubber pad 35 is fixedly connected to a hinge rod B 34.

[0048] As Figure 4 、 Figure 5 shown, the hinge rod A 31 is hinged to the outer wall of the sliding rod 308, the hinge rod B 34 is hinged to the outer wall of the support block 309, the hinge rod B 34 is slidably connected in the inner wall of the hinge rod A 31, the rubber pad 35 is in contact with the inner wall of the groove 33, one end of the buffer spring 32 is fixedly connected to the outer wall of the rubber pad 35, and the other end of the buffer spring 32 is fixedly connected to the inner wall of the hinge rod A 31.

[0049] The above solution is adopted: when the base 1 shakes, the support block 309 will flip over. Since the slide rod 308 is in a fixed state, it drives the hinge rod B34 to move toward the inner wall of the hinge rod A31, compressing the buffer spring 32, and the rubber pad 35 will continue to contact the inner wall of the groove 33, and deform due to compression, thereby increasing the friction between the rubber pad 35 and the hinge rod B34 during movement, thereby reducing the amplitude of vibration and achieving a buffering effect; when the moving block 6 moves to the left, the operator can take or place the paper roll on the placement roller 4, etc. At this time, the buffer module and the support block 309 are retracted, the support block 309 is not in contact with the ground, and the base 1 can be moved.

[0050] like Figures 8 to 10 As shown, the outer wall of the stop block 501 is fixedly connected to the guide block 502, the outer wall of the control block 504 is fixedly connected to the vertical plate 505, the inner wall of the vertical plate 505 is elastically connected to the square block 507 through the elastic member 506, the inner wall of the vertical plate 505 is slidably connected to the short rod 508, the inner wall of the vertical plate 505 is slidably connected to the trapezoidal block 509, the top outer wall of the trapezoidal block 509 is fixedly connected to the pressure rod 510, and the inner wall for placing the roller 4 is provided with an inner groove 9.

[0051] With the above solution, the fixing mechanism 5 can be completely retracted into the inner wall of the placement roller 4 and does not protrude from the outer wall of the placement roller 4. At this time, the operator can put the paper roll on the placement roller 4 and place it between the two sets of stoppers 501. Then, the fixing mechanism 5 is unfolded to move the stoppers 501 on both sides outward. Figure 8 As shown, the outer walls of both sides of the paper roll are in contact with the blocks 501 on both sides respectively, and the blocks 501 can better fix the paper roll to prevent the paper roll from shaking left and right and affecting the processing; an empty groove is provided on the surface of the placement roller 4, and the vertical plate 505 is in the empty groove. By moving the vertical plate 505, the control block 504 can be driven to move and the state of the block 501 can be adjusted; the inner grooves 9 are symmetrically arranged on both sides of the placement roller 4, and two groups of inner grooves 9 are provided on each side. After the square block 507 in the vertical plate 505 is inserted into the inner groove 9, the control block 504 and the block 501 can be fixed, so that the block 501 can be fixed when it is folded or unfolded, and the operation is relatively convenient, which is convenient for the staff to use.

[0052] like Figures 8 to 10As shown, the stop block 501 and the guide block 502 are both slidably connected to the inner wall of the placement roller 4, and the two ends of the rotating rod 503 are hinged to the outer walls of the control block 504 and the stop block 501 respectively, and the control block 504 is slidably connected to the inner wall of the placement roller 4; one end of the short rod 508 is fixedly connected to the outer wall of the square block 507, and the other end of the short rod 508 is slidably connected to the outer wall of the trapezoidal block 509, and the stop block 501 passes through the outer wall of the placement roller 4; one end of the elastic member 506 is fixedly connected to the inner wall of the vertical plate 505, and the other end of the elastic member 506 is fixedly connected to the outer wall of the square block 507, and the square block 507 is slidably connected to the inner wall of the vertical plate 505, and the square block 507 is clamped with the inner groove 9.

[0053] The above solution is adopted: under the action of the guide block 502, the block 501 can only fit the inner wall of the placement roller 4 and move in a straight line. There are four groups of block 501 with equal angles. When the control block 504 moves, it drives the rotating rod 503 to flip. The rotating rod 503 can drive the block 501 to move toward the center or circumference of the placement roller 4 at the same time, thereby changing its retracted or unfolded state; under normal conditions, the elastic member 506 causes the square block 507 to always pop out due to the elastic force and engage with a group of inner grooves 9, thereby fixing the opposing plate 505 and the control block 504. At this time, the short rod 508 is in contact with the inclined surface of the long side of the trapezoidal block 509; when the pressure rod 510 is pressed downward, the trapezoidal block 509 will move downward accordingly, and drive the short rod 508 to move; since the short rod 508 can only move horizontally in the inner wall of the vertical plate 505, it will move along the inclined surface of the trapezoidal block 509 to the short side, and drive the square block 507 to move into the inner wall of the vertical plate 505, and disengage from the inner groove 9, so that the limit of the vertical plate 505 can be released, and the vertical plate 505 is moved to drive the control block 504 to move, thereby adjusting the state of the stop block 501.

[0054] The working principle and use process of the present invention:

[0055] The operator can first take out the placement roller 4, ensure that the fixing mechanism 5 is in the retracted state, and the block 501 is in the inner wall of the placement roller 4, then put the paper roll on the placement roller 4 and place it between the two sets of blocks 501, press the pressure rod 510 downward, and the trapezoidal block 509 moves downward, driving the short rod 508 to move along its inclined surface to the short side, and then driving the square block 507 to move toward the inner wall of the vertical plate 505, breaking contact with the inner groove 9, and releasing the limit of the vertical plate 505.

[0056] The toggle riser 505 drives the control block 504 to move, drives the rotating rod 503 to flip, and the rotating rod 503 drives the stopper 501 to move towards the circumference of the placing roller 4 at the same time, causing the stoppers 501 on both sides to move outwards until the outer walls of both sides of the paper roll are respectively in contact with the stoppers 501 on both sides, clamping and fixing the paper roll; after the fixing is completed, release the pressing rod 510, and the elastic member 506 causes the square block 507 to snap into another set of inner grooves 9 again, fixing the riser 505 and the control block 504, maintaining the unfolded state of the stopper 501, fixing the paper roll, and preventing it from shaking and shifting left and right during the processing.

[0057] Then place the placing block 8 in the moving blocks 6 on both sides. At this time, the moving blocks 6 are on the left side, as Figure 7 shown; fix the starting end of the paper roll on the rotating wheel of the base 1, drive the moving block 6 to move to the right through the electric slide rail 7, the connecting block 301 moves synchronously therewith, and drives the moving rod A302 to move in the inner wall of the fixed rod A303. The hydraulic oil in the fixed rod A303 is squeezed by the moving rod A302 and flows into the fixed rod B305 through the hydraulic oil pipe 304, pushing the moving rod B307 to move downward, stretching the return spring 306, driving the sliding rod 308 to move downward synchronously, unfolding the buffer module and the support block 309, and the support block 309 contacts the ground, playing a role in support and shock absorption.

[0058] Start the rotating wheel of the base 1, pull the paper roll open for conveying through the rotation of the rotating wheel to make a paper tube. During this process, the paper roll and the placing roller 4 will rotate, and the placing block 8 is rotatably connected to both sides of the placing roller 4, so it will not rotate in the moving block 6; during the processing, if the base 1 shakes, the support block 309 flips, drives the articulated rod B34 to move into the inner wall of the articulated rod A31, compresses the buffer spring 32, and the rubber pad 35 contacts the inner wall of the groove 33 and deforms, reducing the vibration amplitude and playing a buffering effect.

[0059] When it is necessary to replace the paper roll, drive the moving block 6 to move to the left through the electric slide rail 7. The connecting block 301 and the moving rod A302 move synchronously. The hydraulic oil gradually loses the force of being squeezed by the moving rod A302. The elastic force of the return spring 306 causes the moving rod B307 to move upward and reset, driving the sliding rod 308 to move upward, flipping and retracting the buffer module and the support block 309. At this time, the support block 309 does not contact the ground, and then the placing roller 4 can be removed. Press the pressing rod 510 and move the riser 505 in the reverse direction, retract the fixing mechanism 5, and place another set of paper rolls on the placing roller 4. The operation is simple, which is convenient for the staff to pick up, place and fix the paper roll.
