[0001] This utility model relates to the field of heat shrink sleeve processing, specifically an open-type heat shrink sleeve slitting and rewinding machine. Background Technology

[0002] Open-type heat shrink sleeves (heat shrink repair tapes) are a type of pipeline anti-corrosion material made of radiation cross-linked polyethylene substrate and special sealing hot melt adhesive. They are characterized by convenient construction, strong applicability, and excellent anti-corrosion performance, and are widely used in the anti-corrosion treatment of oil and gas pipelines, urban pipe networks, and irregularly shaped components.

[0003] In the process of heat shrink sleeve processing, a slitting and rewinding machine is required. It is mainly used to slit wide heat shrink sleeve materials into specified widths as required and rewind them into regular shapes to meet the needs of different orders. However, in order to ensure the stability of the take-up roller during use, the existing slitting and rewinding machine is usually fixed. This leads to longer time consumption during the take-up roller replacement process, which in turn reduces the processing efficiency of heat shrink sleeves. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the take-up rollers of slitting and rewinding machines are usually fixed in order to ensure stability during use. This leads to increased time consumption during the replacement of the take-up rollers, which in turn reduces the processing efficiency of heat shrink sleeves. This utility model proposes an open-type heat shrink sleeve slitting and rewinding machine.

[0005] The technical solution adopted by this utility model to solve its technical problem is: an open-type heat shrink sleeve slitting and rewinding machine, including a machine body, a slitting roller and a slitting assembly respectively installed on the top of the inner cavity of the machine body, and a winding mechanism installed at the bottom of the inner cavity of the machine body; The winding mechanism includes a first motor and a movable slot. The back side of the first motor is fixedly connected to the front side of the machine body. The movable slot is respectively opened on the front and back sides of the machine body. A first support shaft is slidably connected to the inner cavity of the movable slot. A winding roller is fixedly connected to the surface of the first support shaft. A rotating disk is fixedly connected to the output end of the first motor. A plug-in rod is fixedly connected to the front side of the rotating disk. A plug-in slot is opened in the inner cavity of the first support shaft. The surface of the plug-in rod is plugged into the inner cavity of the plug-in slot.

[0006] Preferably, the first support shaft has guide grooves at both the top and bottom, and a guide plate is slidably connected to the inner cavity of the guide groove. The surface of the guide plate is fixedly connected to the inner cavity of the movable groove.

[0007] Preferably, the top of the machine body is provided with a positioning groove, and a second support shaft is slidably connected to the inner cavity of the positioning groove. The surface of the second support shaft is fixedly connected to the inner cavity of the slitting roller. Fixed seats are fixedly connected to the front and back sides of the machine body. The top of the fixed seat contacts the positioning seat, and the inner cavities of the fixed seat and the positioning seat are both in contact with the surface of the second support shaft.

[0008] Preferably, the positioning seat has a connecting groove in its inner cavity, and a connecting rod is inserted into the inner cavity of the connecting groove. The bottom of the connecting rod is fixedly connected to the top of the fixing seat.

[0009] Preferably, the surface of the second support shaft is provided with a fixing groove, and the inner cavities of the positioning seat and the fixing seat are both fixedly connected with fixing rings, the surface of the fixing rings engaging with the inner cavity of the fixing groove.

[0010] Preferably, the inner cavity of the machine body is provided with adjustment grooves on both the front and back sides.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0017] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail. This application discloses an open-type heat shrink sleeve slitting and rewinding machine. (See also...) Figure 1 , Figure 5 and Figure 6 An open-type heat shrink sleeve slitting and rewinding machine includes a machine body 1, with a slitting roller 7 and a slitting assembly 9 respectively installed on the top of the inner cavity of the machine body 1, and a winding mechanism 2 installed on the bottom of the inner cavity of the machine body 1. The winding mechanism 2 includes a first motor 202 and a movable groove 203. The back side of the first motor 202 is fixedly connected to the front side of the machine body 1. The movable groove 203 is respectively opened on the front and back sides of the machine body 1. The inner cavity of the movable groove 203 is slidably connected to a first support shaft 205. The surface of the first support shaft 205 is fixedly connected to a winding roller 201. The output end of the first motor 202 is fixedly connected to a rotating disk 208. The front side of the rotating disk 208 is fixedly connected to an insertion rod 207. The inner cavity of the first support shaft 205 is provided with an insertion groove 206. The surface of the insertion rod 207 is inserted into the inner cavity of the insertion groove 206.

[0018] Reference Figure 5 and Figure 6 The first support shaft 205 has guide grooves 209 at both the top and bottom. A guide plate 204 is slidably connected to the inner cavity of the guide groove 209. The surface of the guide plate 204 is fixedly connected to the inner cavity of the movable groove 203. By setting the guide groove 209, the guide plate 204 can slide in the inner cavity of the first support shaft 205. By setting the guide plate 204, the movement of the first support shaft 205 can be limited, ensuring that the first support shaft 205 moves horizontally and avoiding rotation during the movement of the first support shaft 205, which would affect the connection efficiency of the subsequent insertion groove 206 and insertion rod 207.

[0019] Reference Figure 1 , Figure 2 and Figure 3 The top of the machine body 1 is provided with a positioning groove 8. The inner cavity of the positioning groove 8 is slidably connected to a second support shaft 12. The surface of the second support shaft 12 is fixedly connected to the inner cavity of the slitting roller 7. Fixed seats 11 are fixedly connected to the front and back sides of the machine body 1. The top of the fixed seat 11 contacts a positioning seat 6. The inner cavities of the fixed seat 11 and the positioning seat 6 are both in contact with the surface of the second support shaft 12. The positioning groove 8 is used to position the second support shaft 12, ensuring that the slitting roller 7 can be stably attached to the inside of the machine body 1. The fixed seat 11 is used to support the bottom of the second support shaft 12. At the same time, the positioning seat 6 is used to fix the position of the second support shaft 12, preventing the position of the second support shaft 12 from shifting during use.

[0020] Reference Figure 2 and Figure 3 The inner cavity of the positioning seat 6 is provided with a connecting groove 15, and a connecting rod 10 is inserted into the inner cavity of the connecting groove 15. The bottom of the connecting rod 10 is fixedly connected to the top of the fixed seat 11. Through the setting of the connecting groove 15, the surface of the connecting rod 10 can be inserted into the interior of the positioning seat 6, thereby positioning the position of the positioning seat 6 and improving the clamping stability of the second support shaft 12.

[0021] Reference Figure 2 and Figure 3 The surface of the second support shaft 12 is provided with a fixing groove 13. The inner cavities of the positioning seat 6 and the fixing seat 11 are both fixedly connected with fixing rings 14. The surface of the fixing ring 14 is engaged with the inner cavity of the fixing groove 13. By setting the fixing groove 13, the surface of the fixing ring 14 can be engaged into the interior of the second support shaft 12, thereby restricting the position of the second support shaft 12 and preventing the second support shaft 12 from shaking during use.

[0022] Reference Figure 1 and Figure 4 The machine body 1 has adjustment grooves 5 on both the front and back sides of its inner cavity. A third support shaft 20 is slidably connected to the inner cavity of the adjustment groove 5. A tension roller 3 is fixedly connected to the surface of the third support shaft 20. Limiting plates 19 are fixedly connected to both the front and back sides of the surface of the third support shaft 20. A toothed plate 21 is fixedly connected to the right side of one of the limiting plates 19. A second motor 4 is fixedly connected to the front side of the machine body 1. A gear 16 is fixedly connected to the output end of the second motor 4. The left side of the gear 16 meshes with the right side of the toothed plate 21. The second motor 4 can drive the gear 16 to rotate. The rotation of the gear 16 can drive the toothed plate 21 to move up and down, thereby adjusting the position of the tension roller 3. This allows for adjustment of the tension of the tension roller 3 on the heat shrink sleeve as needed.

[0023] Reference Figure 1 and Figure 4 A positioning rod 18 is slidably connected to the inner cavity of the toothed plate 21. A fixing plate 17 is fixedly connected to the top and bottom of the positioning rod 18. The back side of the fixing plate 17 is fixedly connected to the front side of the machine body 1. The positioning rod 18 supports the position of the toothed plate 21, ensuring that the toothed plate 21 moves vertically. The fixing plate 17 fixes the position of the positioning rod 18 and limits the movement of the toothed plate 21, preventing the toothed plate 21 from moving too far and affecting the normal use of the tension roller 3.

[0024] Working principle: The heat shrink sleeve is cut by the slitting assembly 9. The cut heat shrink sleeve is then attached to the surface of the take-up roller 201. The rotation of the first motor 202 drives the rotating disk 208 to rotate, which in turn drives the insertion rod 207 to rotate. The rotation of the insertion rod 207 drives the first support shaft 205 to rotate, which in turn drives the take-up roller 201 to rotate, thus rewinding the cut heat shrink sleeve. When the take-up roller 201 needs to be replaced, the operator first grasps the first support shaft 205 and moves it upwards. The movement of the first support shaft 205 moves the insertion rod 207 from the insertion rod. When the inside of the receiving groove 206 is disengaged, and the first support shaft 205 moves to the top of the inner cavity of the movable groove 203, the first support shaft 205 can be pulled to the left to completely remove the first support shaft 205 from the inside of the movable groove 203. When installing the take-up roller 201, the guide plate 204 is aligned with the inside of the guide groove 209 to ensure that the first support shaft 205 moves horizontally and to prevent the first support shaft 205 from rotating. When the first support shaft 205 moves to the corner, it can be moved downward so that the surface of the insertion rod 207 is inserted into the inside of the insertion groove 206, ensuring accurate alignment between the insertion groove 206 and the insertion rod 207.

[0025] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
