An automatic sewing machine is required when producing hoisting belts.

[0003] When using an automatic sewing machine to sew a hoisting belt, the hoisting belt needs to continuously move on the top of the operating table, so as to realize the continuous sewing operation of the sewing machine. However, during the movement of the hoisting belt, it may move on the top of the operating table, which will cause the sewing position of the hoisting belt to deviate and affect the actual quality of the hoisting belt. Content of the Utility Model

[0005] To achieve the above object, the utility model adopts the following technical scheme: a long straight line automatic sewing machine for producing hoisting belts, including an operating table, a sewing machine body is arranged in the middle of the top of the operating table, a head body is arranged at the bottom of one side of the sewing machine body, a limiting device is arranged on the top of the operating table, the limiting device includes two L-shaped plates, the bottoms of the two L-shaped plates are symmetrically and fixedly connected to both sides of the top of the operating table respectively, a threaded rod is threadedly connected to the inner wall of the L-shaped plate, a rectangular plate is arranged at one end of the threaded rod, a plurality of rollers are evenly arranged at the bottom of the rectangular plate, a machine box is fixedly connected to the bottom of the operating table, rollers are arranged at the four corners of the bottom of the machine box, and a positioning device is arranged in the middle of the bottom of the machine box.

[0006] The effects achieved by the above components are as follows: By setting a rectangular plate with rollers, under the action of the threaded rod, the threaded rod rotates and expands and contracts on the inner wall of the L-shaped plate. During the expansion and contraction process of the threaded rod, it will drive the rectangular plate to move in the vertical direction, and the rectangular plate will drive the rollers to move synchronously until the outer surface of the roller abuts against the top of the hoisting belt. Then, the roller can limit the hoisting belt while not preventing the normal movement of the hoisting belt, which is beneficial to preventing the hoisting belt from moving on the top of the operating table, thereby preventing the sewing position of the hoisting belt from deviating and ensuring the actual quality of the hoisting belt.

[0007] Preferably, one end of the threaded rod is fixedly connected with a bearing, and the outer surface of the bearing is fixedly connected with the inner wall of the rectangular plate.

[0014] The effect achieved by the above components is that by setting the rubber sleeves, the friction between the rollers and the lifting belt can be increased, and further prevent the lifting belt from shifting on the top of the operating table.

[0015] Preferably, the positioning device includes a positioning plate, the positioning plate is arranged at the bottom of the machine case, threaded insertion rods are symmetrically and fixedly connected to the top of the positioning plate, the outer surfaces of the threaded insertion rods are slidably connected with round hole blocks, and one sides of the two round hole blocks are symmetrically and fixedly connected to the two sides of the machine case respectively.

[0016] The effect achieved by the above components is that by setting the positioning plate, pushing the positioning plate, the positioning plate will drive the threaded insertion rods to slide synchronously on the inner walls of the round hole blocks until the bottom of the positioning plate abuts against the ground, then the friction between the sewing machine and the ground can be increased, making the sewing machine not easily shift and tip over during work.

[0017] Preferably, two threaded hole blocks are threadedly connected to the outer surfaces of the threaded insertion rods, and the two threaded hole blocks are respectively arranged on both sides of the round hole block.

[0018] The effects achieved by the above components are as follows: By setting two screw hole blocks and rotating the two screw hole blocks, when one side of the screw hole block abuts against one side of the round hole block, the positioning plate can be fixed.

[0019] Preferably, one end of the threaded insertion rod is fixedly connected with a stop block, sliding grooves are formed on both sides of the chassis, and the outer surface of the stop block is slidably connected with the inner wall of the sliding groove.

[0020] The effects achieved by the above components are as follows: By setting the stop block, one end of the threaded insertion rod can be blocked. At the same time, when the threaded insertion rod moves, it will drive the stop block to slide synchronously on the inner wall of the sliding groove, making the positioning plate more stable during the movement process.

[0021] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0022] In the present utility model, by setting a rectangular plate with rollers, under the action of the threaded rod, the threaded rod can drive the roller to move synchronously until the outer surface of the roller abuts against the top of the lifting belt. Then, while the roller does not prevent the normal movement of the lifting belt, it can limit the lifting belt, which is beneficial to preventing the lifting belt from moving on the top of the operating table, thereby preventing the sewing position of the lifting belt from deviating and ensuring the actual quality of the lifting belt.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] Example 1, refer to Figures 1-3As shown in the figure, this embodiment discloses a long straight automatic sewing machine for the production of lifting belts, including an operating table 1. In the middle of the top of the operating table 1, a sewing machine body 2 is provided. At the bottom of one side of the sewing machine body 2, a head body 3 is provided. A limiting device 4 is arranged on the top of the operating table 1. The limiting device 4 includes two L-shaped plates 41. The bottoms of the two L-shaped plates 41 are symmetrically and fixedly connected to both sides of the top of the operating table 1 respectively. A threaded rod 42 is threadedly connected to the inner wall of the L-shaped plate 41. One end of the threaded rod 42 is provided with a rectangular plate 43. A number of rollers 44 are evenly arranged at the bottom of the rectangular plate 43. The bottom of the operating table 1 is fixedly connected with a machine box 5. At the four corners of the bottom of the machine box 5, rollers 6 are arranged respectively. In the middle of the bottom of the machine box 5, a positioning device 7 is provided. By setting the rectangular plate 43 with rollers 6, under the action of the threaded rod 42, the threaded rod 42 rotates and expands and contracts inside the inner wall of the L-shaped plate 41. During the expansion and contraction process of the threaded rod 42, it will drive the rectangular plate 43 to move in the vertical direction. The rectangular plate 43 will drive the rollers 44 to move synchronously until the outer surface of the roller 44 abuts against the top of the lifting belt. Then, while the roller 44 can prevent the normal movement of the lifting belt, it can limit the lifting belt, which is beneficial to preventing the lifting belt from moving on the top of the operating table 1, thereby preventing the sewing position of the lifting belt from deviating and ensuring the actual quality of the lifting belt.

[0029] Refer to Figure 2 and Figure 3 As shown in the figure, one end of the threaded rod 42 is fixedly connected with a bearing 45. The outer surface of the bearing 45 is fixedly connected with the inner wall of the rectangular plate 43. By setting the bearing 45, when the threaded rod 42 is rotated, the friction between the threaded rod 42 and the rectangular plate 43 can be reduced, making it more labor-saving to rotate the threaded rod 42; the other end of the threaded rod 42 is fixedly connected with an operating block 46. The outer surface of the operating block 46 is provided with protrusions. By setting the operating block 46, rotating the operating block 46 can drive the threaded rod 42 to rotate. At the same time, the outer surface of the operating block 46 is provided with protrusions, which can effectively increase the friction on the outer surface of the operating block 46 and play an anti-slip role when rotating the operating block 46.

[0030] Refer to Figure 2 and Figure 3 As shown in the figure, round rods 47 are symmetrically and fixedly connected to the top of the rectangular plate 43. The outer surfaces of the two round rods 47 are both slidably connected to the inner wall of the L-shaped plate 41. By setting the round rods 47, when the threaded rod 42 drives the rectangular plate 43 to move, it will drive the round rods 47 connected to the rectangular plate 43 to slide synchronously inside the inner wall of the L-shaped plate 41, which can play a role in limiting the rectangular plate 43; Rubber sleeves 48 are arranged on the outer surfaces of a number of rollers 44. The outer surface of the roller 44 is fixedly connected with the inner wall of the rubber sleeve 48. By setting the rubber sleeve 48, the friction between the roller 44 and the lifting belt can be increased, thereby further preventing the lifting belt from shifting on the top of the operating table 1.

[0031] Refer to Figure 2 and Figure 4 As shown, the positioning device 7 includes a positioning plate 71. The positioning plate 71 is arranged at the bottom of the chassis 5. Symmetrically and fixedly connected to the top of the positioning plate 71 are threaded insertion rods 72. The outer surface of the threaded insertion rods 72 is slidably connected with round hole blocks 73. One side of the two round hole blocks 73 is symmetrically and fixedly connected to the two sides of the chassis 5 respectively. By arranging the positioning plate 71 and pushing the positioning plate 71, the positioning plate 71 will drive the threaded insertion rods 72 to slide synchronously on the inner wall of the round hole blocks 73 until the bottom of the positioning plate 71 abuts against the ground, thus increasing the friction between the sewing machine and the ground and making it not easy for the sewing machine to shift and tip over during operation.

[0032] Refer to Figure 2 and Figure 4 As shown, two threaded hole blocks 74 are threadedly connected to the outer surface of the threaded insertion rods 72. The two threaded hole blocks 74 are respectively arranged on both sides of the round hole blocks 73. By arranging the two threaded hole blocks 74 and rotating the two threaded hole blocks 74, when one side of the threaded hole blocks 74 abuts against one side of the round hole blocks 73, the positioning plate 71 can be fixed; one end of the threaded insertion rod 72 is fixedly connected with a stop block 75. Chute grooves 76 are opened on both sides of the chassis 5. The outer surface of the stop block 75 is slidably connected with the inner wall of the chute grooves 76. By arranging the stop block 75, one end of the threaded insertion rod 72 can be blocked. At the same time, when the threaded insertion rod 72 moves, it will drive the stop block 75 to slide synchronously on the inner wall of the chute grooves 76, making the positioning plate 71 more stable during movement.

[0033] Working principle: When it is necessary to limit the lifting belt, rotate the operation block 46 to drive the threaded rod 42 to rotate. The threaded rod 42 will expand and contract inside the inner wall of the L-shaped plate 41. Under the limitation of the round rod 47, the threaded rod 42 will drive the rectangular plate 43 to move in the vertical direction. The rectangular plate 43 will drive the roller 44 to move synchronously until the rubber sleeve 48 on the outer surface of the roller 44 abuts against the top of the lifting belt. Then, while the roller 44 does not prevent the normal movement of the lifting belt, it can limit the lifting belt, which is beneficial to preventing the lifting belt from moving on the top of the operating table 1 and further preventing the sewing position of the lifting belt from deviating; when it is necessary to position the sewing machine, push the positioning plate 71. The positioning plate 71 will drive the threaded insertion rods 72 to slide synchronously on the inner wall of the round hole blocks 73. When the threaded insertion rods 72 move, they will drive the stop block 75 to slide synchronously on the inner wall of the chute grooves 76 until the bottom of the positioning plate 71 abuts against the ground. Then rotate the two threaded hole blocks 74 so that one side of the threaded hole blocks 74 abuts against one side of the round hole blocks 73, and the positioning plate 71 can be fixed, thus increasing the friction between the sewing machine and the ground and making it not easy for the sewing machine to shift and tip over during operation.
