[0004] In the above solution, the winding cylinder is sleeved on the winding shaft, and then the driving component is used to drive the winding shaft to rotate. However, before that, the end of the cloth needs to be fixed on the winding cylinder through tape or other materials, and there are consumables such as tape, so it needs to be improved. Utility Model Content

[0005] In order to reduce the consumables generated by fixing the cloth on the scroll cylinder, this application provides a fixing device for scroll cloth.

[0006] The fixing device for scroll cloth provided by this application adopts the following technical solution:

[0007] A fixing device for scroll cloth includes an ultrasonic generator, a hand-held welding machine, and a welding head. The hand-held welding machine is connected to the ultrasonic generator through an electric wire. The welding head is arranged at the end of the hand-held welding machine, and the welding head is provided with an arc welding surface matching the outer diameter of the winding cylinder.

[0008] By adopting the above technical solution, the end of the cloth is placed on the surface of the winding cylinder, and then the operator presses the cloth on the surface of the winding cylinder with the arc welding surface of the welding head through the hand-held welding machine, so that the cloth is fixed on the winding cylinder, thereby improving the efficiency of fixing the cloth on the winding cylinder. In addition, the consumables generated by manually fixing the cloth on the winding cylinder with tape are reduced, thereby reducing the production cost.

[0009] Preferably, the welding head is detachably connected to the end of the hand-held welding machine.

[0010] By adopting the above technical solution, since the sizes of the scroll cloths are different, the diameters and lengths of the required winding cylinders are also different. The detachable connection between the hand-held welding machine and the welding head facilitates the replacement of the welding head.

[0011] Preferably, the welding head is threadedly connected to the end of the hand-held welding machine.

[0012] By adopting the above technical solution, the welding head is threadedly connected to the end of the hand-held welding machine, thus facilitating the replacement of the welding head.

[0013] Preferably, a plurality of raised blocks are arranged in an array on the arc welding surface.

[0014] By adopting the above technical solution, a plurality of raised blocks are arranged in an array on the arc welding surface, so that the fabric is tightly pressed and fixed on the winding drum, improving the stability of the fabric fixed on the winding drum.

[0015] Preferably, a cutting knife is provided at one end of the welding head.

[0016] By adopting the above technical solution, during the process of fixing the fabric on the winding drum, the cutting knife provided at one end of the welding head can cut the tail material at the end of the fabric at the same time, thus improving the flatness of the fabric wound on the winding drum.

[0017] Preferably, the height of the cutting knife is greater than the height of the raised block.

[0018] By adopting the above technical solution, the height of the cutting knife being greater than the height of the raised block enables the cutting knife to cut the fabric more easily.

[0019] Preferably, a mark for displaying the position of the cutting knife is provided on the surface of the welding head facing away from the arc welding surface.

[0020] By adopting the above technical solution, since the cutting knife is small, through the arrow mark of the cutting knife position, it can be clearly known where the cutting knife is located on the welding head, avoiding cutting off the fabric at the winding end and thus affecting the production efficiency of the wound fabric.

[0021] Preferably, the hand-held welding machine is a straight-grip welding machine.

[0022] By adopting the above technical solution, the straight-grip hand-held welding machine is convenient for the operator to operate.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] The end of the fabric is placed on the surface of the winding drum, and then the operator uses the hand-held welding machine to press the fabric against the surface of the winding drum with the arc welding surface of the welding head, fixing the fabric on the winding drum, thereby improving the efficiency of fixing the fabric on the winding drum. In addition, the consumables generated by manually fixing the fabric on the winding drum with tape are reduced, thus reducing the production cost. Brief Description of the Drawings

[0029] The following further elaborates on the present application Figures 1-3 with reference to the accompanying drawings.

[0030] The embodiment of the present application discloses a fixing device for a roll of fabric. Referring to Figure 1 , the fixing device includes an ultrasonic generator 1, a handheld welding machine 2, and a welding head 3. The handheld welding machine 2 is connected to the ultrasonic generator 1 through an electric wire. The welding head 3 is arranged at the end of the handheld welding machine 2, and the welding head 3 is provided with an arc welding surface 31 that matches the outer diameter of the winding drum. The welding head 3 in the present application is made of an arc-shaped metal block.

[0031] After the fabric is slit by a roll of fabric machine, the end of the fabric is placed on the surface of the winding drum. Then, the operator presses the fabric against the surface of the winding drum with the arc welding surface 31 of the welding head 3 through the handheld welding machine 2. Since the winding drum is made of PVC material, under the action of the ultrasonic generator 1, the welding head 3 fixes the fabric on the winding drum, thereby improving the efficiency of fixing the fabric on the winding drum. In addition, it reduces the consumables generated by manually fixing the fabric on the winding drum with tape, thereby reducing the production cost.

[0032] The handheld welding machine 2 in this embodiment adopts a straight-grip welding machine, which is convenient for the operator to operate and weld the welding head 3 through the straight-grip welding machine. In other implementation manners, the handheld welding machine 2 can also adopt a grip-type welding machine.

[0033] Further, the end of the handheld welding machine 2 and the welding head 3 are detachably connected. Since the sizes of the rolls of fabric are different, the diameters and lengths of the required winding drums are also different. Therefore, detachable connection of the end of the handheld welding machine 2 and the welding head 3 facilitates the replacement of welding heads 3 of different specifications. Specifically, the welding head 3 in the present application is threadedly connected to the end of the handheld welding machine 2.

[0034] Referring to Figure 2 , further, a number of protruding blocks 32 are arranged in an array on the arc welding surface 31. A number of protruding blocks 32 are arranged in an array on the arc welding surface 31, so as to tightly press and fix the fabric on the winding drum and improve the stability of fixing the fabric on the winding drum.

[0035] Referring to Figure 2 and Figure 3 In order to improve the flatness of the end of the fabric fixed on the take-up reel, a cutting knife 33 is integrally provided at one end of the arc welding surface 31 of the welding head 3. During the process of fixing the fabric on the take-up reel, the cutting knife 33 provided at one end of the welding head 3 can cut the tail material at the end of the fabric, thereby improving the flatness of the fabric wound on the take-up reel. And the height of the cutting knife 33 is greater than the height of the raised block 32, so that the cutting knife 33 can easily cut the end of the fabric.

[0036] Referring to Figure 3 An arrow mark 34 for indicating the position of the cutting knife 33 is provided on the surface of the welding head 3 facing away from the arc welding surface 31. Since the cutting knife 33 is small, it is easy to cause the welding head 3 to be reversed. Through the arrow mark 34 of the position of the cutting knife 33, it can be clearly known that the cutting knife 33 is in the position of the welding head 3, avoiding cutting off the fabric at the take-up end and thus affecting the production efficiency of the wound fabric.

[0037] The implementation principle of a fixing device for wound fabric in an embodiment of the present application is as follows: After the fabric is slit by a wound fabric machine, the end of the fabric is placed on the surface of the take-up reel, and then the operator presses the fabric on the surface of the take-up reel by using the arc welding surface 31 of the welding head 3 through the hand-held welding machine 2. Since the take-up reel is made of PVC material, under the action of the ultrasonic generator 1, the welding head 3 fixes the fabric on the take-up reel, thereby improving the efficiency of fixing the fabric on the take-up reel. In addition, the consumables generated by manually fixing the fabric on the take-up reel with tape are reduced, thus reducing the production cost.
