DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work belong to the protection scope of the utility model.

[0022] Embodiment 1:

[0023] Please refer to Figures 1-5 A novel PVC waterproof material edge sealing device, including base 1, the one end of base 1 is provided with slot 13, the bottom of base 1 is fixedly provided with pressure wheel 11 and hot air pipe 12, the top of slot 13 is provided with support 3, support 3 is installed with clamping assembly 5, clamping assembly 5 includes slide rod 54, slide rod 54 is fixedly installed on the inner side of support 3, two groups of moving frames 53 are slidably installed on slide rod 54, the bottom of moving frame 53 is rotatably connected with limiting disc 55, coiled material 6 is clamped between the limiting disc 55 of the bottom of two groups of moving frames 53, rack 52 is installed on the top of moving frame 53, rack 52 is engaged with gear 51, the rack 52 connected on two groups of moving frames 53 is arranged at the two sides of gear 51 respectively;

[0024] Rack 52 is fixedly arranged at one end of the top of moving frame 53, through hole 531 is formed in the other end of the top of moving frame 53, through hole 531 corresponds with rack 52 on the other moving frame 53, the size of through hole 531 is same with the cross section size of rack 52.

[0025] Specifically, the slide rod 54 is fixed inside the support 3, and the two groups of moving frames 53 can slide on the slide rod 54, so as to adjust the distance between the two groups according to the width of the coiled material 6. The limiting disc 55 at the bottom of the moving frame 53 is in contact with the edge of the coiled material 6, and when the moving frame 53 moves to the middle, the limiting disc 55 gradually approaches the coiled material 6, and finally clamps the coiled material 6 from both sides to realize positioning of the coiled material 6. A gear rack 52 is installed on one side of the top of the moving frame 53, and the gear racks 52 on the two groups of moving frames 53 are located on both sides of the gear wheel 51 and are in meshing engagement with the gear wheel 51. When the gear wheel 51 is rotated, according to the meshing principle of the gear wheel 51 and the gear rack 52, the rotation of the gear wheel 51 will be converted into the linear motion of the gear rack 52, and then drive the two groups of moving frames 53 to move towards or away from each other on the slide rod 54. Since the meshing of the gear rack 52 and the gear wheel 51 has a precise transmission ratio, it can ensure that the two groups of moving frames 53 move synchronously, and the two groups of moving frames 53 and the gear rack 52 are rotationally symmetrically arranged around the gear wheel 51, so that the coiled material 6 is always accurately clamped in the middle position between the two groups of limiting discs 55 at the bottom of the moving frames 53;

[0026] The moving frame 53 is provided with a fixed gear rack 52 at one end of the top, and the other end is provided with a through hole 531 corresponding to the gear rack 52 on the other moving frame 53 and having the same size. During the movement of the moving frame 53, the gear rack 52 can smoothly pass through the corresponding through hole 531 to prevent interference between the moving frames 53 and ensure smooth clamping action.

[0027] Since the moving frame 53 can freely slide on the slide rod 54 and be accurately adjusted by the gear wheel 51 and the gear rack 52 transmission, the clamping assembly 5 can easily adapt to waterproof coiled materials 6 of different widths. The synchronous movement realized by the gear wheel 51 and the gear rack 52 transmission can ensure that the coiled material 6 is accurately clamped in the middle of the two groups of limiting discs 55, achieving high positioning accuracy, facilitating subsequent edge sealing operation, making the edges of the coiled material 6 after edge sealing uniform, neat and beautiful, and effectively improving the edge sealing quality.

[0028] In the clamping assembly 5, the operator only needs to control the rotating gear wheel 51 to quickly realize the synchronous movement of the two groups of moving frames 53 towards or away from each other on the slide rod 54, so as to quickly adjust the distance between the limiting discs 55 to adapt to coiled materials 6 of different widths. This accurate and efficient adjustment method greatly saves the time of clamping the coiled material 6, improves the overall work efficiency, and is more obvious in batch processing of edge sealing of coiled materials 6 of different widths.

[0029] Embodiment 2:

[0030] To realize the control of the clamping assembly 5 for clamping, please refer to Figures 1-5On the basis of embodiment 1, the top of the support 3 is provided with a driving assembly 4, the driving assembly 4 comprises a rotating groove 41 fixedly arranged at the top of the support 3, a worm wheel 43 arranged in the rotating groove 41, the worm wheel 43 is rotatably arranged in the rotating groove 41 through a rotating shaft 42, the bottom of the rotating shaft 42 is fixedly connected with a gear 51;

[0031] One side of the worm wheel 43 is engagedly connected with a worm 44, the worm 44 is rotatably arranged in the rotating groove 41, the connection between the worm 44 and the rotating groove 41 is provided with an anti-skid piece 46, one end of the worm 44 is fixedly connected with a handle 45, the handle 45 is arranged outside the rotating groove 41.

[0032] Specifically, when the operator rotates the handle 45, the handle 45 drives the worm 44 to rotate in the rotating groove 41. Since the worm 44 is engagedly connected with the worm wheel 43, the rotation of the worm 44 will drive the worm wheel 43 to rotate around the rotating shaft 42 in the rotating groove 41, the worm wheel 43 is fixedly connected with the gear 51 through the rotating shaft 42, thus the rotation of the worm wheel 43 will drive the gear 51 to rotate synchronously, so as to enable the clamping assembly 5 to complete the clamping operation.

[0033] The anti-skid piece 46 is used to increase the friction force, so as to avoid the rotation of the worm 44 due to the vibration when the equipment moves, meanwhile, the transmission of the worm wheel 43 and the worm 44 has the self-locking characteristic, when the worm 44 stops rotating, the worm wheel 43 cannot rotate by itself, so as to ensure that the positions of the gear 51 and the moving frame 53 are fixed, the limiting disc 55 can always keep the clamping state of the coiled material 6, so as to prevent the gear 51 from being deflected due to external factors during the edge sealing process, thus preventing the clamping from being loose, and ensuring the stability of the edge sealing operation and the consistency of the edge sealing quality.

[0034] Embodiment 3:

[0035] In order to improve the stability of the coiled material 6 placed in the placing groove 21, please refer to Figure 1 On the basis of embodiment 1 and embodiment 2, the top of the base 1 is fixedly provided with a placing frame 2, the top of the placing frame 2 is provided with a placing groove 21, the bottom of the placing groove 21 is inclined.

[0036] Specifically, the bottom of the placing groove 21 is inclined, this design can make the coiled material 6 naturally lean to the lower side of the inclined surface in the placing groove 21. When the coiled material 6 is slightly disturbed or vibrated by the external environment, it will be more closely attached to the inclined groove bottom due to the action of gravity, thus effectively preventing the coiled material 6 from rolling unnecessarily in the placing groove 21. Compared with the placing groove 21 with a flat bottom, the inclined bottom can provide more definite limiting for the coiled material 6, reduce its degree of freedom in the plane direction, and thus improve the stability of the coiled material 6 placed.

[0037] Working principle: when the device is in use, the operator rotates the handle 45, uses the handle 45 to control the rotation of the worm 44, through the meshing transmission of the worm 44 and the worm gear 43, promotes the rotation of the worm 44 to drive the worm gear 43 and the rotating shaft 42, and then drives the gear 51 to rotate through the rotating shaft 42, according to the meshing principle of the gear 51 and the rack 52, the rotation of the gear 51 makes the rack 52 do linear motion, through the fixed connection of the rack 52 and the moving frame 53, promotes the movement of the rack 52 to drive the two groups of moving frames 53 to move towards or away from each other on the slide rod 54, so as to adjust the distance between the limiting discs 55 to adapt to different width coiled materials 6, and can ensure that the coiled material 6 is accurately located in the middle of the two groups of limiting discs 55, realizes high-precision positioning, and is convenient for realizing the quick fixing and installation of the coiled material 6 with different widths in the middle of the support 3.
