[0002] like Figure 1 As shown, in the prior art, the belt needs to be made by composite vulcanization of layers of films. The belt is usually produced from a mold in a cylindrical shape. The belt needs to have a layer of cylindrical base rubber as the initial cylinder layer. The cylindrical base rubber sheet is sewn together at both ends by a flat film 5 to form a cylinder. The overlapping of the sewn parts of the film 5 will cause uneven thickness of the belt during compounding. In order to prevent the sewn parts of the film 5 from overlapping, the first end 51 and the second end 52 are stacked and single-sided sewing is adopted. A part of the sewing line is located outside the film 5, so that the first end 51 and the second end 52 do not overlap each other after being unfolded and the edges are fitted together. This requires the film 5 to have accurate stitching position during sewing. The existing sewing relies on manual alignment of the first end 51 and the second end 52 of the film 5. When sewing, the feeding end of the film 5 needs to be flattened for sewing. The position of the stitching depends entirely on the feeling of the staff. Therefore, a technical solution is needed to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in this embodiment to clearly and completely describe the technical solution in this embodiment. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] like Figure 2 , Figure 3As shown, this embodiment discloses a film sewing device, including a table top 1, a base 2, a limiting device 3, and a sewing machine 4. The sewing machine 4 is fixedly mounted on the table top 1, and a sewing plane 41 of the sewing machine 4 is flush with the upper end surface of the table top 1. The base 2 is fixedly mounted on the upper end surface of the table top 1, and the base 2 is mounted in the feeding end direction of the sewing plane 41. The film 5 passes through the base 2 and is sewn on the sewing plane 41. The guide plate 23 is fixedly mounted on the upper end surface of the table top 1, and the guide plate 23 is located in the discharging end direction of the sewing plane 41. The guide plate 23 includes a guide surface 231, and the guide surface 231 provides guidance for the discharging of the film 5.

[0024] like Figure 3 , Figure 5 As shown, the base 2 includes a feed channel 21, a discharge channel 216, and a partition 212. The feed channel 21 includes a feed port 211 and a discharge port 215. The feed channel 21 is used for part of the film 5 to pass through. The two ends of the film 5 that need to be sewn pass through the feed channel 21. The discharge port 215 is connected to the discharge channel 216. The discharge channel 216 is connected to the sewing plane 41. After passing through the discharge channel 216, the film 5 enters the sewing plane 41. The lower end surface of the discharge channel 216 is flush with the sewing plane 41, so that the film 5 passing through the discharge channel 216 can smoothly transition to the sewing plane 41 for sewing.

[0025] like Figure 5 As shown, the partition 212 is located in the feed channel 21, and the partition 212 divides the feed channel 21 into a first channel 213 and a second channel 214. The film 5 includes a first end 51 and a second end 52. The first channel 213 is for the first end 51 to pass through, and the second channel 214 is for the second end 52 to pass through. The partition 212 divides the feed channel 21 into the first channel 213 and the second channel 214 to provide space for the first end 51 and the second end 52 of the film 5 to pass through respectively. The first end 51 and the second end 52 can be pressed by the corresponding limit devices 3 respectively, and the first end 51 and the second end 52 are pressed against the side walls of the feed channel 21 to prevent the feed end portion of the film 5 from shifting during the sewing movement process.

[0026] like Figure 5As shown, the caliber of the feed port 211 gradually increases toward the opening direction, and the thickness of the end of the partition 212 toward the feed port 211 gradually decreases. The outwardly expanding opening can more conveniently allow the first end 51 and the second end 52 of the film 5 to penetrate into the first channel 213 and the second channel 214. The caliber of the discharge port 215 gradually decreases toward the discharge channel 216, and the first channel 213 and the second channel 214 converge at the discharge channel 216. The end of the partition 212 toward the discharge port 215 is correspondingly reduced in size with the discharge port 215, and the first end 51 and the second end 52 can converge at the discharge port 215 and be stacked together to enter the sewing plane 41. During sewing, the sewing machine 4 can press the sewn part and cooperate with the two limit devices 3 so that the film 5 between the limit device 3 and the sewing end will not be offset, making the sewing more stable and precise.

[0027] More preferably, the base 2 includes a first baffle 241 and a second baffle 242, the first baffle 241 is located above the partition 212, and the second baffle 242 is located below the partition 212, the first baffle 241 and the partition 212 are used for the first end 51 to pass through, and the space between the second baffle 242 and the partition 212 is used for the second end 52 to pass through, the first baffle 241 and the second baffle 242 are located on the side walls of the feed channel 21, the first baffle 241 and the second baffle 242 can provide a limit for the first end 51 and the second end 52 of the film 5 to press against the side walls of the feed channel 21, prevent the film 5 from being deformed and warped by the pressure block 31 of the limiting device 3, and make the sewing parts of the first end 51 and the second end 52 smoother.

[0028] like Figure 4 As shown, the base 2 is provided with a slot 22, the slot 22 passes through the upper end surface and the lower end surface of the base 2, the slot 22 passes through the feed channel 21, and two limit devices 3 are respectively installed on the upper and lower end surfaces of the base 2. The limit device 3 includes a pressure block 31, a rotating rod 32, a support rod 33, and a tension spring 34. The support rod 33 is fixedly connected to the base 2, and the support rod 33 is partially located above the slot 22. The rotating rod 32 is rotatably connected to the support rod 33. The two ends of the tension spring 34 are respectively connected to the support rod 33 and the rotating rod 32. The rotating rod 32 partially extends into the slot 22 and faces the partition 212. The pressing block 31 is installed on one end of the rotating rod 32 facing the partition 212, and the pressing block 31 is located in the slot 22. The pressing block 31 presses against the film 5 passing through the feed channel 21. The rotating rod 32 receives the pulling force of the tension spring 34 when pressing against the film 5. The pressing block 31 exerts a force on the film 5 toward the side wall of the feed channel 21, so that the first end 51 and the second end 52 press against the side wall of the feed channel 21. During the sewing movement of the film 5, the pressing block 31 can keep the first end 51 and the second end 52 flush, so that the film 5 is more standardized during sewing, and the sewing accuracy is improved.

[0029] More preferably, the pressing block 31 is rotatably connected to the rotating rod 32, and the surface where the pressing block 31 contacts the film 5 is an arc surface. The movement of the film 5 along the feed channel 21 can drive the pressing block 31 to rotate. The pressing block 31 can rotate as the film 5 moves along the feed channel 21 during sewing, thereby reducing the friction between the pressing block 31 and the moving direction of the film 5, making the film 5 more stable and smooth when sewing.

[0030] like Figure 4 As shown, the limiting device 3 includes a screw rod 35 and a guide rod 36. The screw rod 35 passes through the support rod 33 and is threadedly connected to the support rod 33. The screw rod 35 is fixedly connected to the base 2, and the guide rod 36 passes through the support rod 33. The rotation of the screw rod 35 can drive the support rod 33 to move up and down. The support rods 33 of the two limiting devices 3 are connected to the same screw rod 35. The screw rod 35 passes through the base 2. The screw rod 35 includes two threaded sections 351 and a smooth section 352. The smooth section 352 is connected to the base 2 through a bearing. The two threaded sections 351 are located at both ends of the screw rod 35. The thread directions of the two threaded sections 351 are opposite. The rotation of the screw rod 35 can drive the two limiting devices 3 to move closer to or away from each other. When the film 5 is loaded, the screw rod 35 is rotated to move the two limiting devices 3 away from each other and make The pressing block 31 is away from the partition 212, and the film 5 passes through the feed channel 21 and the discharge channel 216, so that the sewing starting end of the film 5 is pressed by the sewing end of the sewing machine 4, and the screw rod 35 is rotated in the opposite direction to bring the two limit devices 3 closer to each other, and the pressing block 31 presses the film 5. The height of the support rod 33 can be adjusted to control the pressure of the pressing block 31 pressing the film 5, and the rotating rod 32 is pulled upward to rotate the rotating rod 32 and then lowered so that the arc surface of the pressing block 31 presses against the film 5 to apply a downward and rightward force to the film 5 at the same time, so that the first end 51 and the second end 52 can always press against the side wall of the feed channel 21 during the movement, so that the first end 51 and the second end 52 always maintain a flush state from feeding to sewing, and the film 5 is more standardized during sewing, and the sewing accuracy is improved.
