Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of processing of bellows protective covers, and particularly relates to a sewing machine. Background Art
[0002] With the development of automation and robotics technologies, the protection of moving parts has become increasingly important. The bellows protective cover, as a flexible and durable protection device, is widely used in various automated equipment and robots. It is made of flexible materials, can adapt to the movement of moving parts, and at the same time provides effective protection.
[0003] In the production process of bellows protective covers, a sewing machine is a key tool. It is used to connect different parts or different materials to form a complete protective structure. However, due to the unique folding shape and material properties of bellows protective covers, the sewing machine faces some challenges in operation.
[0004] Due to the folding design of the bellows protective cover, an ordinary sewing machine is easily restricted in the operation space. Specifically, when sewing and processing the folded part of the bellows protective cover, the sewing machine needs to enter the narrow or curved area of the bellows protective cover, and the folding design of the bellows protective cover makes this operation more difficult. Summary of the Utility Model
[0005] In view of this, the utility model provides a sewing machine, which can expand the operation space and improve the sewing efficiency of the folded part.
[0006] To solve the above technical problems, the utility model provides a sewing machine, including a bracket and a limiting component. A sewing machine body is fixedly connected to the top of the bracket. A limiting component is arranged on the top of the bracket. The limiting component includes a limiting frame, a rack plate, a gear and a clamping plate. A limiting frame is fixedly connected to one side of the top of the bracket. Two symmetrically arranged rack plates are slidably connected to both sides of the middle of the limiting frame. A gear is rotatably connected to the middle of the limiting frame. The gear is meshed with the two rack plates. Clamping plates are fixedly connected to the bottoms of the rack plates, which expands the operation space of the operator and improves the sewing efficiency of the folded part of the bellows protective cover.
[0007] The guiding component includes a guiding frame. A plurality of arrayed guiding frames are fixedly connected to both sides of the bottom of the limiting frame. The rack plates are all in contact with the adjacent guiding frames; this ensures the linear movement path of the rack plates and improves the accuracy and stability of the movement.
[0008] The guiding component further includes an avoidance groove. Avoidance grooves are formed in the middle of the guiding frames. The tops of the clamping plates are all slidably connected to the adjacent avoidance grooves; this enables the clamping plates to pass smoothly during movement, reducing friction and jamming.
[0009] The guiding component further includes a limiting block, and limiting blocks are fixedly connected to both ends of the rack plate; this prevents the rack plate from accidentally disengaging during movement.
[0010] The limiting component further includes a limiting plate, and limiting plates are fixedly connected to one side of the clamping plates close to the middle of the limiting frame. The limiting plates are all inclined, and the tops of the limiting plates are in contact with the bottom of the guiding frame; this better adapts to the shape of the bellows protective cover.
[0011] An adjusting component is arranged at the top of the limiting frame. The adjusting component includes a rotating column. A groove is opened at the top of the limiting frame, and the middle of the groove is rotatably connected with the rotating column. The bottom of the rotating column is fixedly connected to the top of the gear; this realizes the convenient adjustment of the position of the gear.
[0012] The adjusting component further includes a prism and an adjusting block. The center of the top of the rotating column is fixedly connected with the prism. The middle of the prism is slidably connected with the adjusting block. The shape of the adjusting block is the same as that of the groove. A limiting block is fixedly connected to the top of the prism block; this makes the adjustment and fixation of the gear position more flexible and precise.
[0013] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects:
[0014] 1. The clamping plates can simply limit the bellows protective cover, keeping the bellows protective cover in a relatively fixed position. In this way, the staff can pull the bellows protective cover within an appropriate range to stretch the bellows protective cover, so that the sewing part of the sewing machine can more easily enter the narrow or curved area of the bellows protective cover for sewing processing, expanding the operation space of the operator and improving the sewing efficiency of the folded part of the bellows protective cover.
[0015] 2. By changing the rotation direction and speed of the gear, the moving speed and distance of the rack plate and the clamping plates can be controlled, improving the versatility and adaptability of this device for bellows protective covers of different sizes during sewing.
[0016] 3. The gap between the ends of the two limiting plates close to the middle of the limiting frame is smaller, which can better insert into the position of the bellows protective cover closer to the middle of the limiting frame, making the positions where the two clamping plates insert into the bellows protective cover closer, avoiding the skew or distortion of the bellows protective cover caused by the uneven distribution of the folded part of the bellows protective cover inserted, and further improving the stability and precision of the sewing machine during operation.

[0026] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following will combine the appended drawings of the embodiments of the present utility model Figures 1-4 to clearly and completely describe the technical solutions of the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the described embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present utility model.
[0027] As Figures 1-4 shown: This embodiment provides a sewing machine, including a support 100 and a limit component 200. A sewing machine 101 body is fixedly connected to the top of the support 100. A limit component 200 is arranged on the top of the support 100. The limit component 200 includes a limit frame 201, a rack plate 202, a gear 203 and a clamping plate 204. A limit frame 201 is fixedly connected to one side of the top of the support 100. The limit frame 201 is arranged corresponding to the working position of the sewing machine 101. Two symmetrically arranged rack plates 202 are slidably connected to both sides of the middle of the limit frame 201. A gear 203 is rotatably connected to the middle of the limit frame 201. The gear 203 is meshed with the two rack plates 202. Clamping plates 204 are fixedly connected to the bottoms of the rack plates 202. Two sliding grooves are formed in the top of the support 100. The bottoms of the clamping plates 204 are all slidably connected to the adjacent sliding grooves;
[0028] When the sewing machine 101 is working, by controlling the rotation of the gear 203, the two rack plates 202 can be driven to slide in opposite directions, thereby driving the clamping plates 204 to move in the chute. As the distance between the two clamping plates 204 continuously shortens, the clamping plates 204 will insert into the folded part adjacent to the bellows protection cover, so that the clamping plates 204 can simply limit the bellows protection cover and keep the bellows protection cover in a relatively fixed position. In this way, the operator can pull the bellows protection cover within an appropriate range to stretch the bellows protection cover. In this way, the sewing part of the sewing machine 101 can more easily enter the narrow or curved area of the bellows protection cover for sewing processing, expanding the operating space of the operator and improving the sewing efficiency of the folded part of the bellows protection cover. By changing the rotation direction and speed of the gear 203, the moving speed and distance of the rack plate 202 and the clamping plate 204 can be controlled, improving the versatility and adaptability of this equipment when sewing bellows protection covers of different sizes.
[0029] The guiding component 300 is as Figure 4 shown.
[0030] It further includes a guiding component 300. The guiding component 300 includes a guiding frame 301. A plurality of guiding frames 301 arranged in an array are fixedly connected to both sides of the bottom of the limiting frame 201. The rack plates 202 are all in contact with the adjacent guiding frames 301. The width of the widest part of the rack plates 202 is equal to the width inside the guiding frames 301. The guiding component 300 further includes a relief groove 302. Relief grooves 302 are formed in the middle of the guiding frames 301. The thickness of the clamping plates 204 is equal to the width of the relief grooves 302. The tops of the clamping plates 204 are all slidably connected to the adjacent relief grooves 302. The guiding component 300 further includes limiting blocks 303. Limiting blocks 303 are fixedly connected to both ends of the rack plates 202. The width of the limiting blocks 303 is greater than the width of the rack plates 202.
[0031] When the rack plate 202 moves driven by the gear 203, the guiding frame 301 ensures that the moving path of the rack plate 202 always remains straight, which helps the clamping plate 204 to move smoothly and accurately in the chute. The limiting blocks 303 can prevent the rack plate 202 from accidentally disengaging from the guiding frame 301 and the limiting frame 201 during the moving process, thus ensuring the stability and safety of the entire limiting component 200. The relief grooves 302 enable the clamping plates 204 to pass smoothly during the moving process, reducing the failures that may be caused by friction or jamming, improving the durability of the equipment. At the same time, the width of the relief grooves 302 is equal to the thickness of the clamping plates 204, ensuring the accuracy and stability of the clamping plates 204 during movement. Through the cooperative work of the guiding component 300, the working efficiency and stability of the sewing machine 101 can be further improved.
[0032] The limiting component 200 is as Figure 2 , 4As shown
[0033] The limiting component 200 further includes limiting plates 205. Limiting plates 205 are fixedly connected to one side of the clamping plates 204 close to the middle of the limiting frame 201. The limiting plates 205 are all inclined. One side of the limiting plates 205 close to the middle of the limiting frame 201 is inclined towards the middle of the limiting frame 201, and one side of the limiting plates 205 away from the middle of the limiting frame 201 is inclined away from the middle of the limiting frame 201. The tops of the limiting plates 205 are all in contact with the bottom of the guiding frame 301, and the bottoms of the limiting plates 205 are all in contact with the top of the bracket 100;
[0034] In actual work, since the two clamping plates 204 are not on the same straight line, the positions where the bellows protective cover is inserted by the clamping plates 204 are not completely symmetrical. Therefore, through the inclined limiting plates 205, the bellows protective cover can be made to contact the limiting plates 205 first before being limited by the clamping plates 204. The gap between the two ends of the limiting plates 205 close to the middle of the limiting frame 201 is smaller, which can better insert into the position closer to the middle of the limiting frame 201 of the bellows protective cover, making the positions where the two clamping plates 204 are inserted into the bellows protective cover closer, avoiding the skew or distortion of the bellows protective cover caused by the uneven distribution of the folded parts inserted into the bellows protective cover, and further improving the working stability and accuracy of the sewing machine 101. The tops and bottoms of the limiting plates 205 are respectively limited by the bracket 100 and the limiting frame 201, which can ensure the stability of the clamping plates 204 during movement and prevent inaccurate limiting caused by the shaking of the clamping plates 204.
[0035] The adjusting component 400 is as Figure 3 shown
[0036] The adjusting component 400 is arranged on the top of the limiting frame 201. The adjusting component 400 includes a rotating column 401. A groove 402 is opened at the top of the limiting frame 201. The middle of the groove 402 is rotatably connected with the rotating column 401. The bottom of the rotating column 401 is fixedly connected to the top of the gear 203;
[0037] When it is necessary to adjust the rotation of the gear 203, the gear 203 can be rotated by rotating the rotating column 401, and the gear 203 can be adjusted conveniently.
[0038] The adjusting component 400 is as Figure 3 shown
[0039] The adjusting assembly 400 further includes a prism 403 and an adjusting block 404. The top center of the rotating column 401 is fixedly connected to the prism 403. The width of the prism 403 is greater than the diameter of the rotating column 401. The middle part of the prism 403 is slidably connected to the adjusting block 404. The shape of the adjusting block 404 is the same as that of the groove 402. The thickness of the adjusting block 404 is greater than the depth of the groove 402. The top of the prism is fixedly connected to a limiting block 303;
[0040] When rotating, the adjusting block 404 can be pulled to make the adjusting block 404 rise into the middle part of the prism 403. At this time, the adjusting block 404 can be rotated to make the prism 403 rotate synchronously with the rotating column 401, thereby driving the gear 203 to rotate and realizing the adjustment of the gear 203. The limiting block 303 can effectively prevent the adjusting block 404 from rising excessively and separating from the prism 403, resulting in the loss of the adjusting block 404;
[0041] When it is necessary to fix the position of the gear 203, the adjusting block 404 is pressed down to make the adjusting block 404 embed into the inside of the groove 402 to limit the adjusting block 404, thereby restricting the position of the prism 403, so that the rotating column 401 and the gear 203 cannot rotate, thus fixing the position of the gear 203. The convenient flexible adjustment and fixation of the position of the gear 203 are realized through the adjusting assembly 400.
[0042] Working principle:
[0043] When the sewing machine 101 is working, first, by controlling the rotation of the gear 203, two rack plates 202 are driven to slide in opposite directions. This sliding drives the clamping plate 204 to move in the chute at the top of the bracket 100. As the distance between the two clamping plates 204 shortens, the clamping plate 204 is inserted into the folding part adjacent to the bellows protective cover to limit the bellows protective cover and keep it in a relatively fixed position. At the same time, the guiding assembly 300 ensures that the moving path of the rack plate 202 always remains straight. The limiting block 303 prevents the rack plate 202 from accidentally disengaging from the guiding frame 301 and the limiting frame 201 during the movement. The avoidance groove 302 enables the clamping plate 204 to pass smoothly during the movement. In addition, the adjusting assembly 400 enables the user to conveniently adjust the rotation of the gear 203, thereby controlling the moving speed and distance of the rack plate 202 and the clamping plate 204.
[0044] In addition, it should be noted that in the description of the present utility model, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
[0045] The above are the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
