Abstract
Description
Technical Field
[0001] This utility model relates to the field of paper tube processing technology, and in particular to a paper tube conveying and cutting device. Background Technology
[0002] Paper tubes are tubular objects made from paper. Most paper tubes are spiral paper tubes or seamless paper tubes. They are now used in various industries and are an essential factor in the development of various industries in the past and present. Therefore, cutting devices are very important in the production and processing of paper tubes.
[0003] Currently, existing paper tube cutting devices require the paper tube to be fixed during cutting to ensure cutting accuracy and prevent movement that could cause the cutting position to shift and lead to quality issues in the finished paper tube. However, because paper tubes are relatively soft, excessive fixing force can easily cause the paper tube to dent inwards; insufficient fixing force cannot effectively limit the paper tube's movement. To address this issue, existing devices typically include a rubber ring inside the fixing component to cushion the pressure during fixing and reduce paper tube deformation. However, in actual operation, the rubber ring can only reduce the risk of paper tube deformation to a certain extent during clamping. During the cutting process, the downward cutting force applied by the cutting blade can still cause paper tube deformation. Furthermore, existing cutting devices also have a risk of cutting blade displacement during operation, which can also lead to cutting position deviation and seriously affect the quality and accuracy of the finished paper tube. Utility Model Content
[0004] In order to solve the above problems, the purpose of this utility model is to provide a paper tube conveying and cutting device, which solves the problem of easy deformation of paper tubes during cutting.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] More preferably, each clamping mechanism includes a rotating plate rotatably mounted on the rear end of the guide rod on the upper surface of the workbench, two clamping plates fixed at intervals on the front end of the inner side of the rotating plate, a limiting plate fixed on the front end of the rotating plate, and a drive motor fixed on the lower surface of the workbench with its drive end passing through the workbench and fixedly connected to the rotating shaft end of the rotating plate; the cutting mechanism is located between the two clamping plates on the corresponding side.
[0009] More preferably, each cutting mechanism includes a linear driver fixed between two clamping plates on the inner side of the rotating plate and a cutting component fixed at the driving end of the linear driver; the cutting components in the two cutting mechanisms are combined into a ring cutter for completely cutting the paper tube.

[0011] This utility model has the following beneficial effects:
[0012] 1. In this utility model, the design of the anti-deformation guide mechanism effectively prevents the paper tube from deforming during the cutting process, thereby improving the quality of paper tube cutting; during cutting, the anti-deformation sleeve provides support from inside the paper tube, and the clamping mechanism provides stable support from the outside. The combination of the two ensures the stability of the paper tube's shape during cutting in all aspects.
[0013] 2. In this utility model, the cutting component is located between the two clamping plates of the rotating plate.

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0021] A paper tube conveying and cutting device includes a worktable 1, a first conveyor belt 2 embedded in the front side of the upper surface of the worktable 1 for conveying paper tubes, an anti-deformation guide mechanism 3 located in front of the first conveyor belt 2 on the worktable 1 and extending to the rear end above the rear end of the first conveyor belt 2, a pair of clamping mechanisms 4 symmetrically located on both sides of the rear end of the anti-deformation guide mechanism 3 on the worktable 1 for clamping and limiting the paper tubes, a pair of cutting mechanisms 5 respectively located on the inner sides of the clamping ends of the corresponding clamping mechanisms 4 for cutting the paper tubes, and a cutting mechanism 5 located on the worktable 1. The collection mechanism 6 is located on the rear side below the workbench 1 and is used to collect the cut paper tubes. The anti-deformation guide mechanism 3 includes a mounting plate 31 vertically fixed to the front side of the upper surface of the workbench 1, a guide rod 32 horizontally fixed to the rear side of the mounting plate 31 and extending to the rear end of the first conveyor belt 2, a spreading component 33 movably sleeved on the outside of the guide rod 32 and supported in the front end of the paper tube, and an anti-deformation sleeve 34 detachably sleeved on the rear end of the guide rod 32. The clamping ends of the two clamping mechanisms 4 are located on both sides of the anti-deformation sleeve 34.
[0022] During cutting, the anti-deformation sleeve 34 provides support from the inside of the paper tube, while the clamping mechanism 4 clamps the outside of the paper tube. This makes it easier for the paper tube to deform when the cutting mechanism 5, located on the inner side of the clamping end of the clamping mechanism 4, cuts the paper tube, thereby improving the quality of the finished paper tube.
[0023] As a possible implementation of this solution, preferably, the spreading component 33 includes a guide ring 331 movably sleeved on the outside of the guide rod 32, a pair of spreading members 332 symmetrically and movably disposed on both sides of the guide ring 331, and a pair of return springs 333 respectively disposed on both sides inside the guide ring 331 and fixed between the guide ring 331 and the corresponding spreading member 332; by the spreading component 33 sliding outside the guide rod 32, the inside of the front end of the paper tube is spread open, thereby reducing the friction between the paper tube and the guide rod 32 when the paper tube is conveyed by the first conveyor belt 2, reducing the wear of the inner wall of the paper tube, and improving the quality of the finished paper tube.
[0024] As a possible implementation of this solution, preferably, each clamping mechanism 4 includes a rotating plate 41 rotatably mounted on one side of the rear end of the guide rod 32 on the upper surface of the workbench 1, two clamping plates 42 fixedly mounted at intervals on the front end of the inner side of the rotating plate 41, a limiting plate 43 fixedly mounted on the front end face of the rotating plate 41, and a drive motor 44 fixedly mounted on the lower surface of the workbench 1 and whose drive end passes through the workbench 1 and is fixedly connected to the rotating shaft end of the rotating plate 41; the cutting mechanism 5 is located between the two clamping plates 42 on the corresponding side; by placing the cutting mechanism 5 between the two clamping plates 42, it is ensured that the cutting position is at the anti-deformation sleeve 34, thereby preventing deformation during paper tube cutting. At the same time, the remaining paper tube to be cut and the cut paper tube are still clamped by the two clamping plates 42 after cutting, so as to avoid the position displacement of the cutting blade during cutting as much as possible, which greatly improves the accuracy of paper tube cutting and the finished product qualification rate.
[0025] As a possible implementation of this solution, preferably, each set of cutting mechanisms 5 includes a linear driver 51 fixed between two clamping plates 42 on the inner side of the rotating plate 41 and a cutting element 52 fixed at the driving end of the linear driver 51; the cutting elements 52 in the two sets of cutting mechanisms 5 are combined into an annular cutter for completely cutting the paper tube; the cutting of the paper tube is achieved by driving the cutting elements 52 on the corresponding side to move through the two linear drivers 51.
[0026] As a possible implementation of this solution, preferably, the workbench 1 is provided with a discharge port 11 behind the first conveyor belt 2 for the paper tubes to fall after cutting. The inlet of the collection mechanism 6 is connected to the discharge port 11. The collection mechanism 6 includes a conveying channel 61 that is horizontally fixed to the lower surface of the workbench 1 and whose inlet is connected to the discharge port 11, a second conveyor belt 62 that is horizontally embedded in the conveying channel 61, and a collection box 63 placed at the outlet of the second conveyor belt 62 for collecting the paper tubes after cutting. The front end of the second conveyor belt 62 is located below the inlet of the conveying channel 61 and the rear end is located at the outlet of the conveying channel 61. The paper tubes after cutting fall through the discharge port 11 onto the second conveyor belt 62 in the conveying channel 61, and are then transported to the collection box 63 for collection by the conveying action of the second conveyor belt 62. This improves collection efficiency while minimizing the accumulation of paper tubes after cutting.
[0027] The general working principle of this device is as follows:
[0028] 1. When in use, place the paper tube to be cut on the first conveyor belt 2, so that the rear end of the guide rod 32 passes through the front end of the paper tube to be cut. Then press the two opening members 332 inward. Under the action of the return spring 333, the paper tube is opened and supported on the inner wall of the front end. The first conveyor belt 2 is turned on, so that the paper tube to be cut moves forward under the drive of the first conveyor belt 2. At this time, the opening component 33 moves forward with the front end of the paper tube to be cut until the rear end of the paper tube to be cut is located at the anti-deformation sleeve 34 and stops.
[0029] 2. The reverse drive first transmission belt 2 is used to convey the paper tube to be cut. Under the action of the first transmission belt 2, the paper tube to be cut is conveyed to the rear side until the two ends of the rear end abut against the two limit plates 43. The two drive motors 44 are started to drive the corresponding rotating plates 41 to rotate, so that the two clamping plates 42 clamp the paper tube. The linear driver 51 drives the cutting parts 52 to move. The ring cutter composed of the cutting parts 52 of the two sets of cutting mechanisms 5 cuts the paper tube. During the cutting process, the anti-deformation guide mechanism 3 and the clamping mechanism 4 work together to ensure the stability of the paper tube and prevent deformation and displacement. The cutting tool can also be accurately positioned to ensure cutting accuracy.
[0030] 3. After the paper tube is cut, the two linear actuators 51 retract to make the cutting part 52 leave the outside of the paper tube. Then the two drive motors 44 rotate in opposite directions, causing the two clamping plates 42 to release their clamps on the remaining paper tube and the cut paper tube respectively. Under the action of the first conveyor belt 2, the remaining paper tube and the cut paper tube continue to be transported to the rear. When the cut paper tube passes through the discharge port 11, it falls into the conveying channel 61 of the collection mechanism 6. The second conveyor belt 62 transports the cut paper tube to the collection box 63 for collection.
[0031] 4. Repeat steps 2-3 until all the paper tubes have been cut, then stop the operation of this device.

Any equivalent structural transformations made based on the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
