When the wave board head is dragged forward by the upper pressure roller assembly 53, the brush pre-presses the filament surfboard blank passing below, making the surfboard more stable when it moves forward. When the filament surfboard blank passes through the brush, the filament fabric can also be smoothed to avoid excessive concentration of wrinkles on the filament fabric in one place.

[0141] The welding machine for surfboards made of filament fabric of the present invention, by adding an adjusting feeding mechanism 2 and a redesigned lifting head welding mechanism 5, allows the upper and lower layers of fabric of the lifting head to be aligned at the front end by adjusting the feeding mechanism 2 and conveying the lifting head forward.

This welding machine greatly improves the efficiency of spot welding pre-fixing of the lifting head.

[0142] Example 3

[0143] A method for manufacturing a brushed fabric surfboard, using the welding machine of Example 2; includes the following steps:

[0144] Step S01: Select the filament fabric and cut it to obtain the surfboard blank. The length of the lower layer of fabric at the upturned end of the surfboard blank is greater than that of the upper layer of fabric.

[0145] Step S02: Place the surfboard blank on the worktable 3 of the welding machine, and place the curved head in the clamping area of ​​the adjusting feeding mechanism 2; pre-fix the board body by spot welding through the board body welding mechanism 4;

[0146] Step S03, adjust the feeding mechanism 2 to start working:

[0147] The lower adsorption plate 22 adsorbs the lower layer of fabric of the curling head. At the same time, the upper adsorption plate 21 moves downward and adsorbs the lower layer of fabric of the curling head. Then, the second translation module 29 drives the upper adsorption plate 21 to move, so that the front ends of the upper and lower layers of fabric of the curling head are aligned at the front end of the insert plate 231. Then, the first translation module 28 drives the two adsorption plates to clamp the curling head together and move towards the curling head welding mechanism 5. As the insert plate 231 is inserted into the slot 5211 on the lower pressure roller shaft 521, the curling head enters between the upper pressure roller shaft 531 and the lower pressure roller shaft 521. Then, the upper pressure roller shaft 531 presses down to clamp the curling head and outputs it forward. The spot welding module 71 performs spot welding pre-fixing on the output curling head.

[0148] Step S04: After the spot welding of the body and the upturned head is completed, the edge binding cloth is welded around the entire wire mesh surfboard blank using a welding machine. The edge binding cloth covers the spot welding positions of the body and the upturned head.

[0149] Step S05: Inflate the brushed fabric surfboard blank. During the inflation process, the pre-fixed connection between the board body and the upturned head is opened and separated to obtain the finished brushed fabric surfboard.

[0150] Using this method, the alignment of the warp head can be completed by adjusting the feeding mechanism 2, while the spot welding pre-fixation can be completed by the warp head welding mechanism 5, avoiding manual intervention and greatly improving the efficiency of spot welding pre-fixation of the warp head.

At least one slot is provided on the lower pressure roller shaft, and the slot is suitable for inserting a plate. The upper pressure roller assembly has an upper pressure roller shaft above the lower pressure roller shaft, and the lower pressure roller shaft rotates and moves up and down on the frame; At least one spot welding module is configured to move laterally above the frame; The spot welding base is fixed on the frame and located below the spot welding module; The surfboard tip is clamped and output by the upper and lower pressure rollers, and the spot welding module is suitable for spot welding pre-fixing the output surfboard tip on the spot welding base.

6. The welding machine for brushed fabric surfboards according to claim 5, characterized in that, The upper pressure roller assembly includes A pair of pressure roller slides are located on both sides of the frame and slide vertically with the frame respectively. The upper pressure roller shaft has two ends that are respectively rotated with the two pressure roller slides; Two upper drive motors are fixedly mounted on the pressure roller slide, and the upper drive motors are connected to the upper pressure roller shaft to drive the upper pressure roller shaft to rotate; Two second lifting cylinders are fixedly installed on the frame. The second lifting cylinders are connected to the pressure roller slide to drive the upper pressure roller shaft to move up and down.

7. The welding machine for brushed fabric surfboards according to claim 4, characterized in that, Also includes Leveling mechanism, the leveling mechanism includes Level the bracket and fix it in place; Two third lifting cylinders are mounted on the leveling bracket; The brush is connected to two third lifting cylinders; The third lifting cylinder is adapted to drive the brush to press against the upper layer of cloth on the raised head.

8. A method for manufacturing a brushed fabric surfboard, characterized in that, Using the welding machine according to any one of claims 4-7; comprising the following steps: Step S01: Select the filament fabric and cut it to obtain the surfboard blank. The length of the lower layer of fabric at the upturned end of the surfboard blank is greater than that of the upper layer of fabric. Step S02: Place the surfboard blank on the worktable of the welding machine, and place the curved head in the clamping area of ​​the adjusting feeding mechanism; pre-fix the board body by spot welding through the board body welding mechanism; Step S03: Adjust the feeding mechanism to start working: The lower adsorption plate adsorbs the lower layer of fabric of the curling head. At the same time, the upper adsorption plate moves downward and adsorbs the lower layer of fabric of the curling head. Then, the second translation module drives the upper adsorption plate to move, so that the front ends of the upper and lower layers of fabric of the curling head are aligned at the front end of the insert plate. Next, the first translation module drives the two adsorption plates to clamp the curling head together and move towards the curling head welding mechanism. As the insert plate is inserted into the slot on the lower pressure roller shaft, the curling head enters between the upper and lower pressure roller shafts. Then, the upper pressure roller shaft presses down to clamp the curling head and outputs it forward. The spot welding module performs spot welding pre-fixing on the output curling head. Step S04: After the spot welding of the body and the upturned head is completed, the edge binding cloth is welded around the entire wire mesh surfboard blank using a welding machine. The edge binding cloth covers the spot welding positions of the body and the upturned head. Step S05: Inflate the brushed fabric surfboard blank. During the inflation process, the pre-fixed connection between the board body and the upturned head is opened and separated to obtain the finished brushed fabric surfboard.
