[0002] Teflon (polytetrafluoroethylene, PTFE) composite conveyor belts are high-performance industrial conveyor belts, typically made with fiberglass cloth as the base material, coated or impregnated with Teflon to form a Teflon layer. This type of conveyor belt combines the excellent properties of Teflon with the high strength and dimensional stability of fiberglass, making it widely used in various processes requiring drying, curing, heating, or cooling, such as food processing, textiles, reflow soldering of electronic components, and plastics manufacturing.

[0003] However, in practical applications, the connection process of Teflon composite conveyor belts has always been a technical challenge and a weak point. The traditional connection method involves cutting teeth at both ends of the Teflon composite conveyor belt to be connected, then meshing the toothed structures together, and finally heat-sealing them using a hot press. While this method achieves heat-sealing of the Teflon composite conveyor belt, the connection strength is relatively poor, and the process is complex, requiring operation between different machines. Utility Model Content

[0021] Preferred embodiments of the present invention will now be described in more detail. While preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0022] like Figure 1 As shown, this utility model provides a connecting device for Teflon composite conveyor belts, comprising: Support 1, with a hot press platform 2 in the middle of the support 1, and a first accommodating space and a second accommodating space formed below and above the hot press platform 2, respectively; The coating removal mechanism is set in the first accommodating space. The coating removal mechanism includes a base plate 3 and a grinding wheel 4 set above the base plate 3. The base plate 3 is connected to the bracket 1. The grinding wheel 4 is used to remove the Teflon layer on one side of the Teflon composite conveyor belt. A hot melt pressing mechanism is provided in the second accommodating space. The hot melt pressing mechanism includes a liftable hot press plate 5.

[0023] Specifically, to address the problem of insufficient connection strength in the existing Teflon composite conveyor belt toothed hot-melt connection method, the connection device for Teflon composite conveyor belts provided by this utility model divides the interior of the conveyor belt into two accommodating spaces using a hot-pressing platform 2. A coating removal mechanism and a hot-melt pressing mechanism are respectively installed in the two accommodating spaces. The coating removal mechanism removes the Teflon layer on one side of the connecting end of the Teflon composite conveyor belt using a grinding wheel 4, exposing the fiber layer. The exposed fiber layers of the Teflon composite conveyor belt are then overlapped on the hot-pressing platform 2 and hot-melt pressed together using the hot-pressing plate 5 of the hot-melt pressing mechanism. During hot-melt pressing, not only do the Teflon layers fuse together, but the Teflon layers also allow the Teflon impregnated within the fiber layer to fuse together, fully impregnating and wrapping the fiber layer, thus improving the connection strength.

[0024] Optionally, the grinding wheel 4 is provided with crossbeams 6 on both sides, and the crossbeams 6 are provided with guide grooves 7. One end of the two crossbeams 6 is rotatably connected to the bracket 1, and the other end of the two crossbeams 6 extends to the outside of the bracket 1 and is connected through a handle 8. The grinding wheel 4 is connected with guide rods 9 on both sides, and the guide rods 9 pass through the guide grooves 7 and cooperate with the guide grooves 7. One end of the guide rods 9 is provided with a handle 10, and the handle 10 extends to the outside of the bracket 1.

[0025] Specifically, such as Figure 2As shown, one end of the crossbeam 6 is hinged in the first receiving space, and the other end is on the outside of the bracket 1 for easy operation. The hand handle 8 is used to lift and press down the two crossbeams 6. When grinding off the Teflon layer, the crossbeam 6 and the grinding wheel 4 can be lifted, the connecting end of the Teflon composite conveyor belt can be inserted into the bracket 1 and placed on the base plate 3, and then the crossbeam 6 can be pressed down so that the grinding wheel 4 contacts the connecting end of the Teflon composite conveyor belt to grind off the Teflon layer. The handle 10 is pushed so that the grinding wheel 4 moves relative to the connecting end of the Teflon composite conveyor belt under the cooperation of the guide rod 9 and the guide groove 7.

[0026] Optionally, the grinding wheel 4 is connected to a driving component via a rotating shaft 14. The rotating shaft 14 is connected to the center of the grinding wheel 4 and is rotatably connected to the guide rod 9. The driving component includes a first gear 11, a second gear 12, and a drive motor 13. The first gear 11 is connected to the rotating shaft 14, the drive motor 13 is fixed to one side of the guide rod 9, and the output end of the drive motor 13 is connected to the second gear 12, which meshes with the first gear 11.

[0027] Specifically, the drive motor 13 is connected to the guide rod 9, and drives the rotating shaft 14 and the grinding wheel 4 to rotate through the meshing transmission of the second gear 12 and the first gear 11. The rotating shaft 14 can be rotatably connected to the guide rod 9 through a bearing or a rotating fit structure, so that the guide rod 9 does not rotate when the grinding wheel 4 is rotating. The guide rod 9 only moves along the guide groove 7 under the control of the handle 10 to change the grinding position.

[0028] Optionally, the guide groove 7 is a rectangular groove, and the guide rod 9 is a rectangular rod.

[0029] Specifically, the guide rod 9 is a rectangular rod with a rectangular cross section, and a limiting protrusion can be provided on the outer periphery of the guide rod 9 to facilitate limiting and guiding cooperation with the crossbeam 6 or the guide groove 7, so that the guide rod 9 can only move along the length direction of the guide groove 7.

[0030] Optionally, a spring 15 is provided in the guide groove 7, and the two ends of the spring 15 are respectively connected to the groove wall of the guide groove 7 and the guide rod 9.

[0031] Specifically, when the handle 10 is pushed, the guide rod 9 overcomes the elastic force of the spring 15, drives the grinding wheel 4 to move, and stores energy in the spring 15 at the same time, so that the grinding wheel 4 can automatically spring back and reset when the handle 10 is released after grinding is completed.

[0032] Optionally, the upper sides of the base plate 3 are provided with upwardly protruding first limiting parts 16, which cooperate with the crossbeam 6 and are used to limit the crossbeam 6.

[0033] Specifically, the first limiting part 16 can restrict the downward pressure of the crossbeam 6. When the crossbeam 6 is pressed down to the position, it can no longer move downward. The height of the first limiting part 16 is set according to the grinding thickness, so that the Teflon layer on one side of the connecting end of the Teflon composite conveyor belt can be ground off just in time to expose the fiber layer.

[0034] Optionally, a second limiting part 17 protruding upward is provided on the upper side of one end of the base plate 3, and a Teflon composite conveyor belt inlet is formed on the upper side of the other end of the base plate 3. The second limiting part 17 is used to limit the Teflon composite conveyor belt.

[0035] Specifically, the second limiting part 17 can restrict the Teflon composite conveyor belt inserted from the Teflon composite conveyor belt inlet, and is matched with the length setting of the guide groove 7 so that the length of Teflon layer removed each time is equal, which facilitates the overlapping and heat-fusion connection of the connection ends of the two Teflon composite conveyor belts.

[0036] Optionally, the upper surface of the hot press platform 2 is flat and is used to support the Teflon composite conveyor belt. The hot press platform 2 is connected to the first lifting component 18. A third limiting part 19 protruding upward is provided on the upper side of one end of the hot press platform 2. A limiting clamping part 20 connected to the bracket 1 is provided on the upper side of the other end of the hot press platform 2. A hot press inlet is formed on each of the upper two sides of the hot press platform 2. The hot press inlet is used to accommodate the Teflon composite conveyor belt being ground through. The third limiting part 19 is used to limit the Teflon composite conveyor belt. The limiting clamping part 20 is used to clamp the Teflon composite conveyor belt when the hot press platform 2 rises and can limit another Teflon composite conveyor belt.

[0037] Specifically, each of the two hot-pressing inlets accommodates the insertion of a connecting end of a Teflon composite conveyor belt. First, a connecting end of a Teflon composite conveyor belt is inserted into one hot-pressing inlet with the ground surface facing upwards and the bottom surface placed on the hot-pressing platform 2. The insertion length can be limited by the third limiting part 19. Then, the first lifting component 18 is activated to raise the hot-pressing platform 2, causing the limiting clamping part 20 on the bracket 1 to clamp the inserted Teflon composite conveyor belt and fix it. Then, the connecting end of another Teflon composite conveyor belt is inserted into the other hot-pressing inlet. At this time, the limiting clamping part 20 can limit its insertion length. Then, the connecting ends of the overlapping Teflon composite conveyor belts are hot-pressed by the descent of the liftable hot-pressing plate 5 to achieve the heat fusion connection of the connecting ends of the two Teflon composite conveyor belts.

[0038] Optionally, the hot press plate 5 is connected to the bracket 1 via the second lifting component 21.

[0039] Specifically, the hot press plate 5 is raised and lowered under the drive of the second lifting component 21.

[0040] In this embodiment, the hot press plate 5 and the hot press platform 2 form a hot press structure. The hot press plate 5 and the hot press platform 2 of the Teflon hot press can be used. The first lifting component 18 and the second lifting component 21 can both be hydraulic cylinders.

[0041] Optionally, the bottom of the bracket 1 is provided with locking casters 22.

[0042] Specifically, the locking casters 22 at the bottom of the support legs of bracket 1 facilitate the movement and use of the connecting device. When Teflon composite conveyor belts need to be connected, the device can be moved to the working position, and a convenient, efficient and high-strength connection of Teflon composite conveyor belts can be achieved using this one device.

[0043] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
