Description

Technical Field

[0001] This invention relates to the field of pipe conveying equipment, and in particular to a paper tube processing equipment. Background Technology

[0002] The outer surface of some paper tubes is often wrapped with stickers (labels / film stickers) during processing. The core purpose is functional identification, product protection and aesthetic enhancement. The corresponding processing equipment often adopts a horizontal conveyor structure adapted to the tube shape, which can automatically complete the tube conveying and sticker attachment work.

[0003] In some existing paper tube processing machines, when wrapping stickers around the outer surface of the tube, the stickers cannot be effectively flattened relative to the outer surface of the tube. As a result, the stickers still have air bubbles and unevenness after application, which affects the overall quality of the paper tube after processing. Furthermore, it is necessary to waste time on subsequent processing, which has certain limitations in use.

[0004] Therefore, it is necessary to provide a paper tube processing equipment to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide a paper tube processing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, a paper tube processing device is designed that enables stable conveying of tubes and effectively flattens the paper sticker during the conveying process.

[0007] Based on the above ideas, the present invention provides the following technical solution: a paper tube processing equipment, including a worktable, a clamping mechanism and a housing are provided on the worktable, an adjustment component is provided inside the housing for the tube to pass through, and a control component is provided inside the worktable for driving the clamping mechanism and the adjustment component to rotate synchronously; activating the adjustment component can either make it fit against the outer surface of the tube or drive the tube to move away from the clamping mechanism, and the tube can drive the clamping mechanism to move synchronously when it moves.

[0008] As a further aspect of the present invention: the adjustment assembly includes a frustum rotatably mounted on the housing and driven by the control assembly. Two third motors are fixedly mounted on the frustum. A lead screw is fixedly mounted on the output shaft of the third motor. Two partitions are threaded on the outer surface of the lead screw. A second motor is fixedly mounted on the partition and a pull roller is rotatably mounted on the partition. The output shaft of the second motor and the end of the pull roller are connected by gear transmission.

[0009] As a further embodiment of the present invention: the threads on the outer surface of the lead screw are designed in two sections with opposite directions, and two partitions are located on the two sections of threads respectively.

[0010] As a further embodiment of the present invention: the two lead screws are arranged in a cross-shaped manner based on a frustum. When the partition drives the pull roller to fit against the outer surface of the pipe, the pull rollers corresponding to the four partitions are arranged in an array along the circumferential direction of the pipe.

[0011] As a further aspect of the present invention: the control component includes a first motor fixedly installed in the workbench, a support rod fixedly installed on the output shaft of the first motor, a spline shaft fixedly installed at the end of the support rod, the support rod and the frustum being connected by a first transmission system, the spline shaft and the clamping mechanism being connected by a second transmission system, and the spline shaft and the second transmission system being keyed together.

[0012] As a further aspect of the present invention: a track is fixedly installed on the worktable for the clamping mechanism to slide horizontally.

[0013] As a further embodiment of the present invention: the clamping mechanism includes a base slidably mounted on a track, a side plate and a cover rotatably mounted on the base, a main shaft driven by a second transmission system is fixedly mounted on one end of the side plate, and the other end of the side plate rotates synchronously with the cover through a number of elastic buckles, and the end of the cover is provided with a clamping component for clamping pipes and corresponding to the position of the track.

[0014] As a further embodiment of the present invention: the clamping assembly includes a plurality of clamping blocks slidably mounted on the cover, a slide rod slidably mounted in the base, and a push plate slidably mounted in the base and corresponding to the position of the slide rod. The end of the slide rod is rotatably mounted with a conical block that movably fits against the clamping blocks, and a spring is fixedly mounted between the clamping blocks and the cover.

[0015] As a further aspect of the present invention: the clamping block is U-shaped and has two ends, one end of which is used to fit against the outer surface of the pipe fitting, and the other end is movably fitted against the outer surface of the conical block. The clamping block has a tendency to move towards the conical block under the action of the spring.

[0016] As a further embodiment of the present invention: a fourth gear is rotatably mounted inside the base, and racks are provided on the side wall of the push plate and the base away from the push plate. One rack is slidably mounted on the side wall of the base away from the push plate, and the other rack is fixedly mounted on the push plate. Both racks are connected to the fourth gear for transmission, and the two racks are arranged symmetrically and alternately based on the fourth gear.

[0017] Compared with the prior art, the beneficial effects of the present invention are: through the cooperation between the clamping mechanism, the adjusting component and the control component, effective clamping and support can be achieved on both sides of the pipe, so that the pipe can be kept in a horizontal state to complete the overall sticker processing in one go, improve the smoothness of pipe conveying and avoid positional deviation after the sticker is introduced, which is conducive to the uniform winding and stable shaping of the sticker relative to the pipe; the overall operation is smooth and highly synchronized, and it also has the advantages of high efficiency while ensuring processing quality.

[0018] The adjusting component provides support by clamping the pipe fitting, enables effective transport of the pipe fitting, and effectively flattens the sticker on the outer surface of the pipe fitting. During the transport of the pipe fitting, the clamping mechanism can move synchronously with the pipe fitting to maintain support, thereby further improving the transport stability of the pipe fitting and ensuring uniform wrapping and stable shaping of the sticker. Moreover, the adjusting component is applicable to pipe fittings of different shapes and sizes, which greatly improves the applicability of this equipment and can be widely used in the production and processing of pipe fittings in hardware, building materials and other industries.

[0019] Meanwhile, the way the adjusting component drives the tube to move allows for complete transport of the tube. Even when there is a short distance left on one side of the tube, it can still move the tube smoothly. Unlike the way the clamping mechanism drives the tube to move, there will be no area on the tube that has not been in contact with the adjusting component after processing. This design also facilitates the introduction and application of stickers to the entire outer surface of the tube, thus making it more practical overall. Attached Figure Description

[0032] Example 1:

[0033] Please see Figures 1 to 4 This invention provides a paper tube processing device, mainly used to achieve stable conveying of tubes and ensure effective adhesion between the paper and the outer surface of the tube. The device includes a worktable 1, on which a clamping mechanism 2 and a housing 4 are arranged in a left-right correspondence. The clamping mechanism 2 is located on the left side of the housing 4 and can clamp the left side of the tube. The housing 4 is provided with an adjustment component 5 for the tube to pass through. Activating the adjustment component 5 can, on the one hand, adhere to the outer surface of the tube, thereby clamping the right side of the tube, which can provide balanced support on both sides of the tube. On the other hand, after clamping the tube, it can drive the tube to move from left to right. During this process, because the clamping mechanism 2 clamps the left side of the tube, the tube can drive the clamping mechanism 2 to slide synchronously along the worktable 1 when it moves to the right.

[0034] Furthermore, such as Figure 1As shown, the workbench 1 is equipped with a control component 6 for synchronously driving the clamping mechanism 2 and the adjusting component 5. The sticker is introduced between the clamping mechanism 2 and the housing 4. When the adjusting component 5 clamps the pipe and moves it to the right, the control component 6 is activated to rotate the adjusting component 5 and the clamping mechanism 2. At this time, the sticker can automatically wrap around the outer surface of the pipe and move stably to the right. Because the adjusting component 5 clamps and contacts the outer surface of the pipe and drives the pipe to move, when the sticker enters the housing 4 and corresponds to the adjusting component 5, the sticker wrapped around the outer surface of the pipe will be continuously flattened by the adjusting component 5, thereby achieving the effect of smooth operation, uniform wrapping, and stable shaping.

[0035] Among them, such as Figure 1 As shown, a cutting mechanism 3 can also be provided on the right side of the housing 4. When the sticker is flattened on the outer surface of the tube by the adjusting component 5 and transported to the right side of the housing 4 by the adjusting component 5, the cutting mechanism 3 can cut the tube wrapped with the sticker at equal intervals to meet the needs of tubes of different lengths.

[0036] In this embodiment, the clamping mechanism 2 can be a clamp such as a three-jaw chuck, and the cutting mechanism 3 only needs to be able to drive the cutter to move left and right and back and forth. Both are existing mature technologies and will not be described in detail here. The pipe to be processed can be a round pipe, a square pipe, a rectangular pipe or a polygonal pipe, etc., which can be adapted to the processing of any shape of pipe, and its applicability is higher.

[0037] Reference Figures 2 to 4 In this embodiment, preferably, the adjusting component 5 includes a frustum 501 rotatably mounted on the housing 4 and driven by the control component 6. Two third motors (not shown in the figure) are fixedly mounted on the frustum 501. A lead screw 502 is fixedly mounted on the output shaft of the third motor. Two partitions 503 are threaded on the outer surface of the lead screw 502. The thread on the outer surface of the lead screw 502 is designed in two sections with opposite directions. The two partitions 503 are located on the two sections of thread, so that when the third motor starts and drives the lead screw 502 to rotate, the two partitions 503 can move relative to each other.

[0038] Furthermore, such as Figure 4 As shown, a second motor 504 is fixedly mounted on the partition 503, and three pull rollers 505 are rotatably mounted on the partition 503. A first gear 506 and a second gear 507 are fixedly mounted on the output shaft of the second motor 504 and the ends of the pull rollers 505, respectively. The first gear 506 can directly mesh with the second gear 507 to rotate, thereby driving the three pull rollers 505 to rotate when the second motor 504 is started. Alternatively, the first gear 506 can be driven by the second gear 507 through a third gear 508 rotatably mounted on the partition 503, which can also drive the three pull rollers 505 to rotate after the second motor 504 is started.

[0039] In the above structure, the two lead screws 502 are arranged in a cross shape based on the frustum 501, so that the partition 503 on one set of lead screws 502 moves up and down, and the partition 503 on the other set of lead screws 502 moves back and forth. This causes one partition 503 to drive the pull roller 505 to move up and down closer to the pipe, and the other partition 503 to drive the pull roller 505 to move back and forth closer to the pipe. This can effectively clamp the right side of the pipe, and after the second motor 504 is started, the pull roller 505 can also effectively transport the pipe.

[0040] Reference Figures 1 to 3 In this embodiment, preferably, the control component 6 includes a first motor 601 fixedly installed in the workbench 1. The output shaft of the first motor 601 is fixedly mounted with a support rod 602. A spline shaft 603 is fixedly mounted on the left end of the support rod 602. The support rod 602 is connected to the frustum 501 via a first transmission system 604. The spline shaft 603 is connected to the clamping mechanism 2 via a second transmission system 605. The second transmission system 605 can also move along the axial direction of the spline shaft 603. Thus, when the pull roller 505 rotates and drives the pipe to move to the right, and the pipe drives the clamping mechanism 2 to move to the right, the second transmission system 605 can move synchronously with the clamping mechanism 2 and move along the spline shaft 603.

[0041] In the above structure, the first transmission system 604 and the second transmission system 605 can adopt belt pulley transmission, sprocket transmission or gear transmission, as long as they can transmit the rotation of the support rod 602 to the frustum 501 and the rotation of the spline shaft 603 to the clamping mechanism 2, thereby driving the frustum 501 and the clamping mechanism 2 to rotate synchronously; here, the first transmission system 604 and the second transmission system 605 are both existing mature technologies, and will not be described in detail here.

[0042] Furthermore, such as Figure 2 As shown, a track 606 is also fixedly installed on the workbench 1, and the clamping mechanism 2 is movably sleeved on the track 606. When the pipe fitting drives the clamping mechanism 2 to move, the clamping mechanism 2 can move horizontally and stably along the track 606.

[0043] In use, the left side of the tube is clamped by the clamping mechanism 2, and the right side is inserted into the frustum 501. The third motor is started, which drives the partition 503 and the pull roller 505 to move accordingly via the lead screw 502 until the pull roller 505 is in contact with the outer surface of the tube. Then, the first motor 601 and the second motor 504 are started, and the sticker is guided to the outer surface of the tube at the same time. The first motor 601 drives the frustum 501 and the pull roller 505 to rotate in the circumferential direction of the frustum 501 via the support rod 602 and the first transmission system 604, and drives the clamp to rotate synchronously via the spline shaft 603 and the second transmission system 605. At this time, the clamp and the pull roller 505 can drive the tube to rotate accordingly, so that the sticker is wrapped around the outer surface of the tube. During this process, the second motor 504 drives the pull roller 505 to rotate, which on the one hand moves the tube to the right, and on the other hand presses the sticker flat on the outer surface of the tube.

[0044] Of course, if the length of the pipe is very short and its right end cannot be inserted into the frustum 501 after being placed on the clamping mechanism 2, the clamping mechanism 2 can be manually pushed along the track 606 to move closer to the housing 4 after the sticker is introduced, so that the right end of the pipe can be inserted into the frustum 501, and then the third motor and the second motor 504 can be started in sequence.

[0045] In summary, through the cooperation of the clamping mechanism 2, the pull roller 505, and the lead screw 502, effective clamping and support can be achieved on both sides of the tube, allowing the tube to be kept horizontal and the entire sticker processing to be completed in one go. This improves the stability of the tube's conveying and avoids positional deviation after the sticker is introduced, which in turn helps the sticker to be wrapped evenly and stably shaped relative to the tube. The overall operation is stable and highly synchronized, and it also has the advantages of high efficiency while ensuring processing quality.

[0046] Through the cooperation of structures such as the pull roller 505, the second motor 504, and the first gear 506, the pull roller 505, which clamps the pipe fitting, can be driven to rotate. On the one hand, it can effectively transport the pipe fitting, and on the other hand, it can effectively flatten the sticker on the outer surface of the pipe fitting. During the pipe fitting transport process, the clamping mechanism 2 can move synchronously with the pipe fitting to maintain support, thereby further improving the transport stability of the pipe fitting and ensuring that the sticker is wrapped evenly and stably shaped. At the same time, the lead screw 502 drives the pull roller 505 to move through the partition 503, so that the pull roller 505 can be used for pipe fittings of different shapes and sizes, thereby greatly improving the applicability of this equipment and making it widely applicable to pipe fitting production and processing scenarios such as hardware and building materials.

[0047] Meanwhile, the rotation of the pull roller 505 drives the movement of the tube, which can achieve complete conveying of the tube. When there is a short distance left on the left side of the tube, the drive of the pull roller 505 is still effective. Unlike the way the clamping mechanism 2 moves to the right to drive the movement of the tube, there will be no area on the tube that is not in contact with the pull roller 505 after processing. This design is also conducive to the introduction and application of stickers to the entire outer surface area of ​​the tube, so the overall practicality is higher.

[0048] Example 2:

[0049] Please see Figures 1 to 8 Based on Embodiment 1, to further improve the processing efficiency of pipe fittings, the clamping mechanism 2 is improved: The clamping mechanism 2 now includes a base 201 slidably mounted on a track 606. A side plate 203 and a cover 204 are rotatably mounted on the base 201. A main shaft 202, driven by a second transmission system 605, is fixedly mounted on the left end of the side plate 203. The side plate 203 and the cover 204 rotate synchronously through several elastic latches (not shown in the figure). These elastic latches can be arranged equidistantly along the circumference of the side plate 203. Further, as... Figure 5 As shown, the right end of the cover 204 is provided with a clamping component 7 for clamping the left side of the pipe and corresponding to the position of the track 606; when the clamping component 7 contacts the track 606, the clamping component 7 can automatically release the clamping limit on the left side of the pipe.

[0050] Among them, such as Figure 5 As shown, the bottom of the base 201 extends downward and is movably sleeved on the outside of the spline shaft 603 for rotatably mounting the second transmission system 605. The second transmission system 605 and the spline shaft 603 are connected by a key, and the two can rotate synchronously. The second transmission system 605 can be displaced relative to the axial direction of the spline shaft 603 based on the lower extension of the base 201.

[0051] Reference Figures 5 to 7 In this embodiment, preferably, the clamping assembly 7 includes four clamping blocks 701 slidably mounted on the right end of the cover 204, a slide rod 702 slidably mounted in the base 201, and a push plate 705 slidably mounted in the base 201 and corresponding to the position of the slide rod 702. A conical block 704 is rotatably mounted on the end of the slide rod 702. The clamping block 701 is U-shaped and has two ends. One end can fit against the outer surface of the pipe to perform a clamping function, and the other end can movably fit against the outer surface of the conical block 704. A spring 703 is fixedly installed between the clamping block 701 and the cover 204. The spring 703 makes the clamping block 701 tend to move closer to the center.

[0052] In the above structure, such as Figure 7As shown, when the clamping block 701 moves towards the center to clamp the pipe fitting, it can drive the conical block 704 and the slide rod 702 to move to the right. At this time, the bottom of the slide rod 702 contacts the push plate 705 and pushes the push plate 705 to extend from the right side of the base 201. When the main shaft 202 drives the cover 204 to rotate through the side plate 203 and the elastic buckle, the cover 204 drives the elastic buckle to contact the surface of the slide rod 702 in sequence. At this time, the elastic buckle in contact with the slide rod 702 can retract to avoid the slide rod 702, so that the slide rod 702 can pass over the elastic buckle to avoid interference. During this process, the other elastic buckles remain extended, so that the side plate 203 and the cover 204 can rotate synchronously. Specifically, the latch in the elastic buckle can be inserted into the cover 204 from the side plate 203 under the action of the elastic element, or from the cover 204 into the side plate 203. When the latch rotates with the side plate 203 or the cover 204, its surface corresponding to the slide rod 702 is provided with a chamfer, so that when the latch contacts the slide rod 702, the chamfer allows the latch to disengage, thereby allowing the slide rod 702 to pass over the latch to avoid interference. The elastic buckle is an existing mature technology and will not be described in detail here.

[0053] Furthermore, such as Figure 6 As shown, the push plate 705 has an inverted T-shaped design, and the base 201 has a cavity 205 inside to allow the slide rod 702 and the push plate 705 to slide left and right. When the slide rod 702 moves to the right and pushes the push plate 705 to extend from the right side of the base 201, the push plate 705 can contact the track 606 during the process of moving to the right with the base 201. At this time, the push plate 705 retracts into the base 201 to reset and drives the slide rod 702 and the conical block 704 to move to the left to reset. At this time, the conical block 704 can drive the four clamping blocks 701 to move away from each other, thereby automatically releasing the clamping limit on the pipe.

[0054] Furthermore, such as Figure 8 As shown, a fourth gear 706 is rotatably mounted inside the base 201. Racks 707 are provided on the left side of the base 201 and on the push plate 705. One rack 707 is slidably mounted on the left side of the base 201, and the other rack 707 is fixedly mounted on the left side of the push plate 705. Both racks 707 are connected to the fourth gear 706, and the two racks 707 are arranged symmetrically and alternately based on the fourth gear 706, thus allowing relative movement between the push plate 705 and the rack 707 slidably mounted on the base 201. Through this design, after the base 201 moves to the right or left and contacts the track 606, it can drive the four clamping blocks 701 to move away relatively.

[0055] In use, the clamping mechanism 2, pull roller 505, and lead screw 502 can effectively clamp and smoothly transport the pipe fitting. The working process and effect of this part are the same as in Embodiment 1, and will not be repeated here. The difference is that when the base 201 corresponds to the right side of the track 606, the push plate 705 can contact the track 606 and drive the push plate 705 to retract into the base 201. When the base 201 corresponds to the left side of the track 606, the rack 707 slidably mounted on the base 201 can retract into the base 201. In both of these ways, the slide rod 702 can drive the conical block 704 to move towards the side plate 203, thereby driving the four clamping blocks 701 to move away from each other and automatically release the limit on the pipe fitting. When the base 201 corresponds to the right side of the track 606, the base 201 has moved to the limit along the track 606 under the drive of the rightward movement of the pipe fitting. At this time, the limit on the left side of the pipe fitting is automatically released, which can achieve non-stop operation so that the pull roller 505 can continue to drive the pipe fitting to move to the right.

[0056] Compared to Embodiment 1, through the cooperation of structures such as clamping block 701, conical block 704, sliding rod 702 and push plate 705, when the base 201 corresponds to the left or right side of the track 606, the four clamping blocks 701 can be driven to move away from each other and automatically release the clamping limit on the left side of the pipe. When corresponding to the right side, the release of the limit can achieve non-stop operation, allowing the pull roller 505 to continue to drive the pipe to move to the right. When corresponding to the left side, the release of the limit can facilitate the rapid assembly of the pipe into the cover 204, thereby further improving the overall processing efficiency and further reducing manual intervention in the processing process.

[0057] Example 3:

[0058] Please see Figures 1 to 10 Based on Embodiment 2, in order to further improve the processing efficiency of pipe fittings, a cylinder 9 is rotatably installed inside the workbench 1. The cylinder 9 is rotatably installed on the workbench 1 via a short rod 8 and a torsion spring, and a torsion spring (not shown in the figure) is sleeved on the outer surface of the short rod 8. The torsion spring makes the short rod 8 and the cylinder 9 have a tendency to automatically reset after rotation.

[0059] Furthermore, a guide groove 10 is provided on the outer surface of the cylinder 9, and a locking block 206 is movably installed on the bottom of the base 201 and slidably engaged in the guide groove 10. After unfolding, the guide groove 10 has an overall inclined straight-line design. When the base 201 moves horizontally along the track 606, the cylinder 9 and the short rod 8 can be rotated through the locking block 206 and the guide groove 10. Of course, the axial length of the guide groove 10 along the cylinder 9 is adapted to the horizontal movable dimension of the base 201 along the track 606. When the base 201 moves to the left or right side of the track 606, the base 201 can drive the locking block 206 to move to the left or right edge of the guide groove 10. At this time, because the clamping block 701 automatically releases the clamping limit on the pipe, the cylinder 9 can automatically reset under the action of the short rod 8 and the torsion spring, and then drive the base 201 to automatically reset along the track 606 through the guide groove 10 and the locking block 206.

[0060] In use, the clamping mechanism 2, pull roller 505 and lead screw 502 and other structures can effectively clamp and smoothly transport the pipe fittings; through the clamping block 701, conical block 704, slide bar 702 and push plate 705 and other structures, the clamping limit on the left side of the pipe fitting can be automatically released when the base 201 corresponds to the left or right side of the track 606. The working process and effect of this part are the same as in embodiment 2, and will not be repeated here. The difference is that when the pull roller 505 rotates and drives the pipe to move to the right, and the pipe moves the base 201 along the track 606 through the clamping block 701 and the cover 204, the base 201 also drives the clamping block 206 to move along the guide groove 10, causing the cylinder 9 and the short rod 8 to rotate. When the base 201 corresponds to one side of the track 606, and the four clamping blocks 701 move away from each other to release the pipe limit, the pipe can still continue to move to the right under the action of the pull roller 505, while the cylinder 9 can be reset in the opposite direction under the action of the short rod 8 and the torsion spring, thereby driving the base 201 to automatically move to the left and reset along the track 606.

[0061] It should be noted that the resetting force of the torsion spring acting on the cylinder 9 through the short rod 8 is greater than the elastic force of the spring 703 acting on the clamping block 701. This allows the rack 707, which is slidably mounted on the base 201, to retract into the base 201 after the cylinder 9 is reset, so that the four clamping blocks 701 are relatively far apart and will not affect the rapid placement of the pipe into the cover 204.

[0062] Compared to Embodiment 2, through the cooperation of structures such as cylinder 9, guide groove 10, base 201, and locking block 206, after the clamping limit on the left side of the pipe is automatically released, the base 201 can be automatically reset from right to left along the track 606. This eliminates the need for manual repositioning of the base 201, further facilitating the rapid assembly of the pipe into the cover 204 and improving overall processing efficiency. The overall design results in higher processing efficiency and less manual intervention, reducing the workload of workers and effectively lowering the possibility of safety accidents. Therefore, the practicality of this equipment is further improved.
