DETAILED DESCRIPTION OF THE EMBODIMENTS [[ID=*16]]

[0013] The following further describes the present utility model in conjunction with the drawings and embodiments. Embodiment 1

[0014] Referring to Figure 1-2 as shown, a heating joint device for plastic backing cloth includes a base 1, and vertical mounting plates 2 are provided on both the left and right sides of the base 1; it also includes a heating and pressing component, which includes a screw 3, a guide rod 4, a sliding seat 6, a gantry bracket 9, a shaft 10, a roller 11 and an electric slip ring 14. The screw 3 and the guide rod 4 are horizontally arranged side by side between the two mounting plates 2, and one end of the screw 3 is drivingly connected to a motor 5; the sliding seat 6 is slidably mounted on the guide rod 4 and is threadedly connected to the screw 3. A first cylinder 7 is fixed to its top, and a vertical guide rail 8 is fixed to its bottom; the gantry bracket 9 is longitudinally arranged, and is slidably mounted up and down on the vertical guide rail 8, and its top is fixedly connected to the output end of the first cylinder 7; the shaft 10 is longitudinally fixed inside the gantry bracket 9, the roller 11 is rotatably mounted on the shaft 10, and four heating tubes 12 are arranged in a circumferential array on one side of the roller 11; the electric slip ring 14 is sleeved on the shaft 10, its stator is fixed on the shaft 10 and is connected to a wire 15, and its rotor is electrically connected to the four heating tubes 12.

[0015] More specifically, in order to monitor the temperature of the roller 11 in real time, a temperature measuring resistor 13 is installed on one side of the roller 11, and the temperature measuring resistor 13 is electrically connected to the rotor of the electric slip ring 14.

[0016] During use, the connecting ends of the two plastic tarp are overlapped under the heating and pressing assembly. The heating tube 12 heats the roller 11. When the temperature of the roller 11 reaches the working temperature, the first cylinder 7 drives the gantry bracket 9 to move downward along the vertical guide rail 8, thereby driving the roller 11 to press onto the plastic tarp. Subsequently, the motor 5 drives the screw 3 to rotate, and then drives the slide 6 to move horizontally along the guide rod 4, causing the roller 11 to roll on the plastic tarp, so that the two layers of plastic tarp are evenly and reliably adhered together.

[0017] The structure of this device is simple and highly practical. By heating the roller 11 to roll and press the joint of the plastic tarp, the joint has high stability and is not affected by the specifications of the plastic tarp. Embodiment 2

[0018] As a preferred embodiment of the present utility model, an auxiliary pressing assembly is added on the basis of Embodiment 1, specifically:

[0019] In this embodiment, auxiliary pressing assemblies are provided on both the front and rear sides of the heating and pressing assembly. The auxiliary pressing assembly includes a horizontal support plate 16, a second cylinder 17, and a pressing plate 18. The horizontal support plate 16 is fixedly installed between the two mounting plates 2. The second cylinder 17 is vertically fixed at the center of the horizontal support plate 16, and its output end passes through the horizontal support plate 16 and is fixedly connected to the center of the top of the pressing plate 18. The pressing plate 18 is horizontally arranged, and two vertical guide rods 19 are provided on its top. The guide rods 19 slidably penetrate through the horizontal support plate 16.

[0020] Before joining, first, the two overlapping layers of plastic tarp are pressed by the two groups of auxiliary pressing assemblies to prevent the plastic tarp from shifting during the joining process: start the second cylinder 17, which drives the pressing plate 18 to move downward under the guidance of the guide rods 19, so that the pressing plate 18 presses and fixes the two overlapping layers of plastic tarp.

[0021] The present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the purpose of the present utility model, and the changed content still falls within the protection scope of the present utility model.
