Description

Technical Field

[0001] The utility model relates to the technical field of organ guiding, in particular to a guiding device for a sewing machine. Background Technique

[0002] The bellows protective cover is a commonly used protective device in automation and robotics, used to protect moving parts such as lead screws and guide rails. It is usually made of flexible materials, which can adapt to the movement of the moving parts while maintaining a tight fit. During the production process of the bellows protective cover, a sewing machine is a key tool for connecting different parts or different materials to form a complete protective structure.

[0003] However, due to the folding design of the bellows protective cover, during the sewing process, the processed protective covers may pile up together, and a guiding device is needed to guide and clean the piled-up protective covers after processing. The existing guiding devices often use a push plate to intermittently guide and clean the processed bellows protective covers, with a simple structure and low cost.

[0004] However, since the push plate works intermittently, it may not be able to achieve continuous cleaning work, resulting in unnecessary pauses in the production process and being unable to effectively handle the continuously generated protective covers under high-speed production, thus affecting the overall production efficiency. Summary of the Utility Model

[0005] In view of this, the utility model provides a guiding device for a sewing machine, which can continuously process the bellows protective cover and improve the overall production efficiency.

[0006] To solve the above technical problems, the utility model provides a guiding device for a sewing machine, including a bracket and a guiding component. The guiding component is arranged at the bottom of the bracket. The guiding component includes a guiding frame, guiding columns and clamping plates. The bottom of the bracket is fixedly connected with the guiding frame. Two symmetrically distributed guiding columns are fixedly connected to the middle of the guiding frame. Multiple clamping plates arranged in a circular array around the guiding columns are fixedly connected to the middle of the guiding columns, which can effectively and continuously process the continuously generated bellows protective covers under high-speed production and improve the overall production efficiency.

[0007] One end of each guiding column is fixedly connected with a first sprocket in the middle, and the two first sprockets are connected by a first chain; that is, the synchronous rotation of the guiding columns is realized through chain drive, improving the coordination and efficiency of operation.

[0008] A plurality of arrayed notches are opened on both sides of the guiding frame; that is, it is convenient to observe the movement state of the bellows protective cover.

[0009] On one side of the bracket, a feeding groove is provided. In the middle of the feeding groove, a feeding component is arranged. The feeding component includes a feeding column and a reinforcing rib. The feeding column is rotatably connected to the middle of the feeding groove. In the middle of the feeding column, a plurality of reinforcing ribs arranged in a circular array around the feeding column are fixedly connected; this ensures the smoothness of the feeding process.

[0010] On the side of the bracket close to the feeding groove, two limiting blocks symmetrically arranged with the feeding column as the center are fixedly connected; this ensures the accurate position of the bellows protective cover during the feeding process and prevents deviation or distortion.

[0011] In the middle of one end of the feeding column and in the middle of one end of the adjacent guiding column, second sprockets are fixedly connected. The second sprockets are connected by a second chain; this realizes the linkage between the feeding column and the guiding column and improves the overall coordination of the conveying.

[0012] A protective cover is fixedly connected between the guiding frame and the bracket. The second sprockets and the second chain are both located inside the protective cover; this protects the safety of the staff and avoids direct contact with the transmission components.

[0013] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects:

[0014] 1. Through this continuous guiding and cleaning method, it is possible to effectively and continuously process the bellows protective cover continuously generated under high-speed production, avoid unnecessary pauses during the production process, and improve the overall production efficiency.

[0015] 2. The guiding column enables the folded parts of the bellows protective cover to be evenly dispersed when rotating, avoiding damage caused by excessive pressure due to local accumulation of the bellows protective cover.

[0016] 3. The guiding frame limits both sides of the bellows protective cover to prevent it from slipping or being misaligned. The limiting block positions the bellows protective cover during the feeding process to prevent it from deviating or being distorted during the feeding process. The limiting block is flush with the inner wall of the feeding groove to ensure a smooth transition of the bellows protective cover during the feeding process. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] For the purpose, technical solution and advantages of the embodiments of the present utility model to be more clear, the following will combine the attached 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.

[0026] As Figures 1-4 shown: This embodiment provides a sewing machine guiding device, including a bracket 100 and a guide assembly 200. The guide assembly 200 is arranged at the bottom of the bracket 100. The guide assembly 200 includes a guide frame 201, a guide post 202 and a clamping plate 203. Installation openings are provided at the four corners of the top of the bracket 100. The guide frame 201 is fixedly connected to the bottom of the bracket 100. Two symmetrically distributed guide posts 202 are fixedly connected to the middle of the guide frame 201. A plurality of clamping plates 203 arranged in a circular array around the guide post 202 are fixedly connected to the middle of the guide post 202. A plurality of notches 103 arranged in an array are provided on both sides of the guide frame 201;

[0027] The support plate and the guiding device are integrally installed at the bottom of the sewing machine through the installation opening. When the sewing machine is working, the completed part of the bellows protective cover is guided to the tops of the two guiding columns 202, and then the two guiding columns 202 are driven to rotate. While the guiding columns 202 are rotating, the clamping plate 203 can be driven to rotate along with the guiding columns 202. During the rotation of the clamping plate 203, it can be inserted into the folded part of the bellows protective cover at the top. As the clamping plate 203 rotates, it can drive the bellows protective cover to move. As the part of the bellows protective cover located at the top of the guiding column 202 moves, the stacked part of the bellows protective cover located at the top of the sewing machine will also be driven and unfolded accordingly. The guiding column 202 enables the folded part of the bellows protective cover to be evenly dispersed during rotation, avoiding damage caused by excessive pressure due to local accumulation of the bellows protective cover. The clamping plate 203 ensures that it can effectively grasp the protective cover during rotation. During the movement of the bellows protective cover, the guiding frame 201 limits the two sides of the bellows protective cover to prevent it from slipping or being misaligned. The movement state of the bellows protective cover can be effectively observed through the notch 103. Through this continuous guiding and cleaning method, the continuously generated bellows protective cover during high-speed production can be effectively processed, avoiding unnecessary pauses during the production process and improving the overall production efficiency.

[0028] The feeding assembly 300 is as Figure 1 , 2 shown in Figure 3.

[0029] A feeding groove 104 is formed on one side of the bracket 100. The feeding assembly 300 is arranged in the middle of the feeding groove 104. The feeding assembly 300 includes a feeding column 301 and a reinforcing rib 302. The feeding column 301 is rotatably connected to the middle of the feeding groove 104. A plurality of reinforcing ribs 302 arranged in a circular array around the feeding column 301 are fixedly connected to the middle of the feeding column 301. The length of the feeding column 301 is the same as that of the guiding column 202. Two limiting blocks 105 symmetrically arranged with the feeding column 301 as the center are fixedly connected to one side of the bracket 100 close to the feeding groove 104. The sides of the limiting blocks 105 close to the feeding column 301 are located in the same plane as the inner wall of the adjacent feeding groove 104.

[0030] When the bellows protective cover moves downward into the top of the guiding column 202, the middle part of the bellows protective cover will contact the feeding column 301. By controlling the rotation of the feeding column 301, the middle part of the bellows protective cover can be pushed towards the feeding groove 104. The reinforcing rib 302 increases the stability of the feeding column 301, making the gripping force of the feeding assembly 300 on the bellows protective cover stronger, ensuring the smoothness of the feeding process during high-speed production. As the feeding column 301 rotates, the bellows protective cover is smoothly fed into the feeding groove 104 and further enters the next processing link of the sewing machine. The limiting block 105 positions the bellows protective cover during the feeding process to prevent it from shifting or twisting. The limiting block 105 being flush with the inner wall of the feeding groove 104 ensures a smooth transition of the bellows protective cover during the feeding process, further improving the production quality.

[0031] The protective cover 108 is as Figure 1 shown

[0032] One end of the guiding column 202 is fixedly connected with a first sprocket 101 in the middle. The two first sprockets 101 are connected by a first chain 102. One side of the guiding frame 201 is fixedly connected with a motor. The output shaft of the motor is fixedly connected with the middle part of one end of the adjacent guiding column 202. One end of the feeding column 301 and the middle part of one end of the adjacent guiding column 202 are both fixedly connected with a second sprocket 106. The second sprockets 106 are connected by a second chain 107. A protective cover 108 is fixedly connected between the guiding frame 201 and the bracket 100. The second sprockets 106 and the second chain 107 are both located inside the protective cover 108.

[0033] When the sewing machine is working, by controlling the operation of the motor, the first sprocket 101 can be driven to rotate. Then, through the transmission of the first chain 102 and the first sprocket 101, the other guiding column 202 rotates synchronously. At the same time, the second sprocket 106 will also rotate through the transmission of the second chain 107, thereby driving the feeding column 301 to rotate. Since the working position of the feeding column 301 is relatively high and easy for the staff to contact, the protective cover 108 can prevent the second sprockets 106 and the second chain 107 from contacting the staff and protect the safety during the transmission process.

[0034] Working principle:

[0035] After the sewing machine is processed, the bellows protection cover is guided to the top of the guide post 202. The guide post 202 rotates driven by the motor. Through the transmission of the sprocket and chain, the two guide posts 202 rotate synchronously. The rotation of the guide post 202 drives the rotation of a plurality of clamping plates 203 fixed thereon. These clamping plates 203 can be inserted into the folded part of the bellows protection cover, thereby driving the protection cover to move. As the clamping plates 203 rotate, the bellows protection cover is evenly dispersed, avoiding damage caused by local accumulation. At the same time, the protection cover moves on the top of the guide post 202, and then drives the stacking part located on the top of the sewing machine to unfold, ensuring the smooth movement of the protection cover. The feeding post 301 is controlled to rotate to push the middle part of the bellows protection cover towards the feeding groove 104. The reinforcing rib 302 increases the stability of the feeding post 301, ensuring the smoothness of the feeding process during high-speed production.

[0036] In addition, it should be noted that in the description of the present invention, unless otherwise clearly defined 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 invention can be understood according to specific situations.

[0037] The above is the preferred embodiment of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle described in the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
