Description

Technical Field

[0001] The utility model relates to the technical field of heat shrinkable tube manufacturing, in particular to a heat shrinkable tube conveying and cutting device. Background Art

[0002] A heat shrinkable tube, also known as a heat shrink tube, is a special plastic tube with the special function of shrinking when heated. It is mainly used for insulation protection of wires, cables, various pipeline joints, etc. The following is the general production process of heat shrinkable tubes: 1. Raw material preparation: Select appropriate polyolefin raw materials such as polyethylene and polyvinyl chloride according to the product performance requirements and pre-treat them. 2. Extrusion molding: Extrude the raw materials through an extruder into a tubular shape, and then make it preliminarily formed through a cooling and shaping device. 3. Crosslinking treatment: Crosslink the extruded tube through electron beam or chemical methods to form a three-dimensional network structure between molecules, improving the heat resistance and mechanical strength of the product. 4. Expansion and winding: Wind up the processed tube for standby. 5. Cutting: Cut the wound heat shrinkable tube into corresponding lengths; first, the wound heat shrinkable tube needs to be transported to the cutting device through a transportation device. Existing transportation devices often use the method of two belts and pulleys to squeeze and transport the heat shrinkable tube. However, due to the relatively soft material and coiled shape of the heat shrinkable tube itself, the traditional transportation method uses two belts and pulleys to squeeze and move the heat shrinkable tube, but this method often fails to effectively straighten the heat shrinkable tube completely, and there is also a problem of transmission slipping because the heat shrinkable tube is extremely easy to be compressed. This not only increases the complexity of subsequent cutting operations but also affects the accuracy of the length of the cut heat shrinkable tube. Summary of the Utility Model

[0031] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that may be included in at least one implementation manner of the present utility model. The "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is separate or selectively mutually exclusive with other embodiments.

[0032] Embodiment

[0033] Referring to Figures 1 to 6 , which is an embodiment of the present utility model. This embodiment provides a heat-shrinkable tube conveying and cutting device, including a guiding component 100 and a cutting component 200, both of which are installed on a workbench 300. The guiding component 100 is used for conveying a tube body 400, and the cutting component 200 is used for cutting the tube body 400 of the guiding component 100. The guiding component 100 is composed of a driving member 101, a transmission belt 102 and a pressing wheel 103. The transmission belt 102 is wound around a pulley of the driving member 101, and rack teeth 102a are arranged at equal intervals on its outer surface. One end of the pressing wheel 103 is arranged at a supporting end of the driving member 101, and a plurality of equally spaced convex blocks 103a are arranged on its outer surface. The convex blocks 103a can roll and be embedded in the gaps between adjacent rack teeth 102a of the transmission belt 102.

[0034] Micropores 103a-1 are provided on the convex blocks 103a. The arc side 103a-3 of the convex blocks 103a protrudes outward from the chamber 103a-2 of the convex blocks 103a and abuts between the two rack teeth 102a.

[0035] Specifically, the main task of the guiding component 100 is to smoothly convey the pipe body 400, while the cutting component 200 is responsible for precisely cutting the pipe body 400 passing through the guiding component 100 to ensure that each cut section meets the specification requirements. By arranging equally spaced racks 102a on the outer surface of the conveyor belt 102 (i.e., the belt), when the driving member 101 drives the conveyor belt to move the pipe body 400, the rack 102a will squeeze the surface of the pipe body 400, forming equally spaced indentations 400b on the pipe body 400. In this way, the pipe body 400 can move stably and can be better straightened, facilitating subsequent cutting. A pressure wheel 103 is arranged on the guiding component 100 to tighten the conveyor belt 102, solving the problems of jitter during the high-speed transmission of the conveyor belt 102 and slippage between the belt and the pulley. At the same time, the convex blocks 103a on the outer surface of the pressure wheel 103 are embedded in the racks 102a of the conveyor belt 102, similar to the meshing relationship between a rack and a gear, which can further improve the stability of the operation of the conveyor belt 102. The rib 102a is made of hollow soft material, and micropores 103a-1 are opened at both ends thereof. When the rib 102a contacts the conveyor belt 102, the rib 102a reduces the jitter that occurs during the operation of the conveyor belt 102 by a slow air leakage method. Even at high speeds, the conveyor belt 102 can stably convey the pipe body 400, thereby improving the cutting efficiency of the pipe body 400;

[0036] By arranging equally spaced racks 102a on the outer surface of the conveyor belt 102 (i.e., the belt), when the driving member 101 drives the conveyor belt, the rack 102a will form a series of equally spaced indentations 400b on the surface of the pipe body 400. This design not only ensures the stability of the pipe body 400 during movement but also effectively helps to straighten the pipe body 400 during its travel, creating favorable conditions for subsequent precise cutting.

[0037] In addition, a pressure wheel 103 is arranged on the guiding component 100, which closely adheres to the conveyor belt 102, solving the possible jitter problem during high-speed transmission and the potential slippage phenomenon between the belt and the pulley. The outer surface of the pressure wheel 103 is equipped with convex blocks 103a that match the racks 102a of the conveyor belt 102. This design is similar to the meshing of a gear and a rack, significantly enhancing the stability of the operation of the conveyor belt 102. At the same time, the convex blocks 103a also have the effect of stably squeezing the soft pipe body 400 to move on the conveyor belt.

[0038] More notably, the bump 103a is made of a hollow soft material, and micropores 103a-1 are formed at both ends thereof. When the bump 103a contacts the conveyor belt 102, the slow air leakage through the micropores 103a-1 can effectively reduce the vibration generated by the conveyor belt 102 during high-speed operation. In this way, even at high speeds, the conveyor belt 102 can operate smoothly, ensuring the smooth transportation of the pipe body 400, thereby greatly improving the cutting efficiency and accuracy of the pipe body 400;

[0039] In the embodiment, as Figure 2 、 Figure 3 shown, the driving member 101 is composed of a support plate 101a, a driving motor 101b, an output wheel 101c, and a driven wheel 101e. The driving motor 101b, the output wheel 101c, and the driven wheel 101e are all mounted on the support plate 101a, and the support plate 101a serves as the support end of the driving member 101. The output wheel 101c is connected to the output shaft of the driving motor 101b, and both the output wheel 101c and the driven wheel 101e are belt wheels of the driving member 101. A plurality of driven wheels 101e are on the same horizontal line to ensure that a plane is formed in the gap 100a area of the conveyor belt 102;

[0040] In the embodiment, as Figure 4 shown, a bearing 103c is installed in the shaft hole 103b of the pressure wheel 103. The bearing 103c is connected to the shaft rod 103e. One end of the shaft rod 103e is fixed on the limit plate 103g. The limit plate 103g can slide on the sliding piece 103f through screws. The sliding piece 103f is mounted on the support plate 101a. This can make the rolling resistance of the pressure wheel 103 smaller, avoid the misalignment between the bump 103a on the outer surface of the pressure wheel 103 and the rack 102a of the conveyor belt 102. At the same time, the sliding piece 103f mounted on the support plate 101a can adjust the degree of the pressure wheel compressing the conveyor belt, which is convenient for flexible use;

[0041] In the embodiment, as Figure 4 、 Figure 5 shown, a baffle 103a-4 is provided in the chamber 103a-2 of the bump 103a. The crease of the baffle 103a-4 protrudes towards the micropore 103a-1, and the baffle 103a-4 can perform a circular segment motion at the crease;

[0042] Specifically, in the chamber 103a-2 of the bump 103a, a baffle 103a-4 is designed, with its crease facing the micropore 103a-1, such that the baffle 103a-4 can perform a segmental circular motion centered on the crease. When the conveyor belt runs at high speed and generates vibrations, the gas pressure in the chamber increases, and due to its structural characteristics, the baffle 103a-4 forms a barrier in the chamber, creating an effect similar to that of a Tesla valve, that is, significantly resisting the outward flow of gas from the chamber, thereby preventing the rapid loss of gas and making the shock absorption process more linear and stable. On the contrary, when the gas pressure drops to a certain extent, the shape and position of the baffle 103a-4 do not pose too much obstruction to the gas entering the chamber from the outside, which enables the chamber to quickly replenish gas and helps the bump quickly return to its original shape. In this way, even at high speeds, the bump can continuously provide effective shock absorption;

[0043] In the embodiment, as Figure 1 shown, the cutting assembly 200 is composed of a housing 201, a through groove 201a, and a cylinder 202. The housing 201 is disposed on the workbench 300. A through groove 201a for guiding the pipe body 400 is provided on the housing 201. A cylinder 202 is provided at the top of the housing 201, and a cutter is provided on the output shaft of the cylinder 202 and moves within the through groove 201a;

[0044] Specifically, the pipe body 400 led out from the conveyor belt 102 moves to the through groove 201a on the housing 201, and the output shaft of the cylinder 202 drives the cutter to move downward along the through groove 201a to cut the pipe body 400. The function of the through groove 201a is to ensure the linearity of the cutting path and the cutting accuracy. After the pipe body 400 is completely cut and separated, the output shaft of the cylinder 202 retracts, moving the cutter away from the pipe body and returning to the initial position to complete the cutting process.
