Description

Technical Field

[0001] This invention relates to the field of down jacket processing technology, and in particular to a template positioning device for a template sewing machine used in down jacket production. Background Technology

[0002] Down jackets are outer garments filled with down feathers. They are large and rounded in shape. The most common fillings for down jackets are goose down and duck down. In the manufacturing process of down jackets, after the down is filled, the back panel needs to be further sewn to prevent the down from moving left and right inside the fabric. The equipment used for this sewing process is a template sewing machine.

[0003] Currently, during the sewing process, the sewing template along with the down jacket material needs to be pushed into the fixing device. The fixing device has a fixing plate, a transmission mechanism, and a clamping mechanism for directly holding the sewing template. The entire fixing device works with the machine head to complete the sewing under the drive of the moving mechanism in the sewing machine. However, the fixing device of the template sewing machine lacks effective, accurate, and stable positioning measures for the template. The overall adjustability is low, the adaptability is low, and the positioning and installation process is relatively laborious and complicated. Summary of the Invention

[0004] The purpose of this invention is to solve the problem of inconvenient positioning in the prior art, and to propose a template positioning device for a template sewing machine for down jacket production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a template positioning device for a template sewing machine in down jacket production, comprising a bracket, two sets of positioning components connected to the side wall of the bracket via an adjustment mechanism, each positioning component comprising a clamping head, a base box fixed to the bottom of the clamping head, a pressure plate fixed to the inner wall of the clamping head, the pressure plate being inclined and made of an elastic material, a pressing groove being provided on the side wall of the clamping head, an inclined push block being connected to the inner wall of the pressing groove via a connecting spring, a pressing wheel being connected to the inside of the base box via a driving device, the pressing wheel abutting against the inclined push block, and a propulsion mechanism for driving the inclined push block to move laterally being provided inside the base box.

[0006] In the template positioning device of the template sewing machine for down jacket production mentioned above, the driving device includes a drive motor fixed to the inner wall of the bottom box, the output shaft of the drive motor is fixed to the main shaft, the inner wall of the bottom box is fixed to the fixing box, the fixed box is connected to the drive shaft through the locking mechanism, the drive shaft is fixed to the pressure wheel, and the drive shaft and the main shaft are fitted with a belt.

[0007] In the template positioning device of the template sewing machine for down jacket production described above, the locking mechanism includes a sliding rod that slides against the bottom of the fixed box. A locking block is fixed to the side wall of the sliding rod. The sliding rod is rotatably connected to the drive shaft. The interior of the fixed box is filled with electrorheological fluid.

[0008] In the template positioning device of the template sewing machine for down jacket production described above, the pushing mechanism includes a pushing plate, which abuts against an inclined push block. The side of the inclined push block that abuts against the pushing plate is an inclined surface. The upper end plate of the main shaft is threaded. The pushing plate is threadedly connected to the upper part of the main shaft. A guide rod is fixed at the upper end of the bottom box, and the guide rod passes through the pushing plate.

[0009] In the template positioning device of the template sewing machine for down jacket production described above, the adjustment mechanism includes a mounting plate fixed to the side wall of the support, a large-amplitude adjustment motor fixed to the side wall of the mounting plate, a large-amplitude lead screw fixed to the output shaft of the large-amplitude adjustment motor, a large-amplitude slider threaded through the side wall of the large-amplitude lead screw, and the large-amplitude slider abutting against and slidingly connected to the side wall of the support.

[0010] In the template positioning device of the template sewing machine for down jacket production described above, two small sliding grooves are opened through the side wall of the large sliding block, and the two small sliding grooves are symmetrically arranged. Two clearance grooves are opened through the side wall of the bracket, and small sliding blocks are slidably connected to the inner walls of the two clearance grooves. The small sliding blocks are fixed to the corresponding clamping heads.

[0011] In the template positioning device of the template sewing machine for down jacket production described above, the position of the relief groove corresponds to that of the small slide groove, the length of the relief groove is greater than that of the small slide groove, the inner wall of the small slide groove is rotatably connected to a small lead screw, the small lead screw is threadedly connected to the small slider, the side wall of the large slider is fixed with a small adjustment motor, and the output shaft of the small adjustment motor is fixed to the small lead screw.

[0012] Compared with existing technologies, the advantages of this invention are:

[0013] 1. In this invention, the relative position of the two clamping heads can be adjusted slightly, which makes it easier to adapt to the installation of various workpieces and enhances the overall adjustability. The large slider can drive the two small sliders to move at the same time, so the overall position can be adjusted while keeping the relative position of the two clamping heads stable, which facilitates the position adjustment after clamping and positioning.

[0014] 2. In this invention, the end face of the inclined push block is inclined, which can form a lateral component force when squeezed, thereby allowing the inclined push block to be pushed into the clamping head by the push plate, thereby pushing the clamping wheel to move laterally to press the positioning column. The belt itself can deform and stretch while maintaining effective conveying capacity, so it can still maintain effective driving capacity after the lateral position of the clamping wheel is adjusted.

[0015] 3. In this invention, the surface of the pressure roller itself is elastic and can deform, so it can maintain an effective rotary conveying state through deformation when the pressure is large, which facilitates the transfer of the positioning plate;

[0016] 4. In this invention, the main shaft is driven by a belt to rotate, which in turn drives the clamping wheel to rotate. The rotation of the clamping wheel enables the rolling conveying of the positioning column, reducing the resistance during the movement of the positioning column and facilitating the insertion and positioning of the positioning column.

[0017] 5. In this invention, during the installation process, the pressure plate is squeezed and pushed upward to a horizontal state, and the deformation of the pressure plate itself will give the positioning plate a strong downward squeezing force, thereby enabling the positioning plate to be effectively clamped and positioned.

[0018] 6. After installation, the positioning plate will be blocked by the clamping rollers, making it impossible to move the positioning plate directly outward. When disassembly is required, the clamping rollers must be moved first to make room for the positioning plate to be removed and disassembled smoothly, ensuring accurate and stable positioning.

[0025] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0026] Example

[0027] Reference Figure 1-4 A template positioning device for a template lining machine used in down jacket production includes a support 1. The side wall of the support 1 is connected to two sets of positioning components via an adjustment mechanism. The positioning components include a clamping head 2. A base box 26 is fixed to the bottom of the clamping head 2. A pressure plate 3 is fixed to the inner wall of the clamping head 2. The pressure plate 3 is inclined and made of elastic material. A pressing groove 4 is provided on the side wall of the clamping head 2. An inclined push block 13 is connected to the inner wall of the pressing groove 4 via a connecting spring 14. A pressing wheel 7 is connected to the inside of the base box 26 via a driving device. The pressing wheel 7 abuts against the inclined push block 13. A propulsion mechanism for driving the inclined push block 13 to move laterally is provided inside the base box 26.

[0028] The drive unit includes a drive motor 8 fixed to the inner wall of the base box 26. The output shaft of the drive motor 8 is fixed to a main shaft 9. A fixed box 5 is fixed to the inner wall of the base box 26. A drive shaft 6 is connected inside the fixed box 5 through a locking mechanism. The drive shaft 6 is fixed to the pressure wheel 7. The drive shaft 6 and the main shaft 9 are fitted with a belt 10.

[0029] The locking mechanism includes a slide rod 15, which slides against the bottom of the fixed box 5. A locking block 16 is fixed to the side wall of the slide rod 15. The slide rod 15 is rotatably connected to the drive shaft 6. The interior of the fixed box 5 is filled with electrorheological fluid. When energized, the electrorheological fluid will change from liquid to solid, thus restricting the movement of the slide rod 15 and achieving effective limiting.

[0030] The propulsion mechanism includes a propulsion plate 11, which abuts against an inclined push block 13. The side of the inclined push block 13 that abuts against the propulsion plate 11 is an inclined surface. The upper end plate of the main shaft 9 is threaded, and the propulsion plate 11 is threadedly connected to the upper part of the main shaft 9. A guide rod 12 is fixed at the upper end of the bottom box 26. The guide rod 12 passes through the propulsion plate 11 and can restrict the rotation of the propulsion plate 11, thereby allowing the propulsion plate 11 to move up and down under the drive of the main shaft 9. The end face of the inclined push block 13 is inclined, which can form a lateral force when squeezed, thereby allowing the inclined push block 13 to be pushed by the propulsion plate 11 to move into the clamping head 2, thereby pushing the pressure wheel 7 to move laterally and press the positioning column. The belt 10 itself can deform and stretch while maintaining effective conveying capacity, so it can still maintain effective driving capacity after the lateral position of the pressure wheel 7 is adjusted. The surface of the pressure wheel 7 itself is elastic and can deform, so it can maintain an effective rotational conveying state through deformation when the pressure is large, which facilitates the transfer of the positioning plate.

[0031] The adjustment mechanism includes a mounting plate 17 fixed to the side wall of the bracket 1. A large amplitude adjustment motor 18 is fixed to the side wall of the mounting plate 17. A large amplitude lead screw 19 is fixed to the output shaft of the large amplitude adjustment motor 18. A large amplitude slider 20 is threaded through the side wall of the large amplitude lead screw 19. The large amplitude slider 20 abuts against and slides against the side wall of the bracket 1. The large amplitude slider 20 is limited by the bracket 1 and cannot rotate. Therefore, it can move laterally under the drive of the large amplitude lead screw 19, thereby adjusting its own position.

[0032] Two small sliding grooves 21 are provided through the side wall of the large sliding block 20. The two small sliding grooves 21 are symmetrically arranged. Two clearance grooves 25 are provided through the side wall of the bracket 1. Small sliding blocks 24 are slidably connected to the inner walls of the two clearance grooves 25. The small sliding blocks 24 are fixed to the corresponding clamping heads 2.

[0033] The clearance groove 25 corresponds to the position of the small slide groove 21. The length of the clearance groove 25 is greater than that of the small slide groove 21. The inner wall of the small slide groove 21 is rotatably connected to the small lead screw 23. The small lead screw 23 is threadedly connected to the small slider 24. The side wall of the large slider 20 is fixed with a small adjustment motor 22. The output shaft of the small adjustment motor 22 is fixed to the small lead screw 23. The small adjustment motor 22 drives the small lead screw 23 to rotate. The small slider 24 is limited by the deflection of the small slide groove 21 and the clearance groove 25, which enables it to adjust its own position laterally. This allows for the adjustment of the relative position of the two clamping heads 2 to adapt to more working conditions.

[0034] In this invention, during actual positioning and installation, the positioning plate on the line template is aligned with the position of the clamping head 2, and then the positioning plate is pushed into the clamping head 2. This process will cause the pressure plate 3 to be squeezed and pushed upward to a horizontal state, and the deformation of the pressure plate 3 itself will give the positioning plate a strong downward squeezing force, thereby enabling the positioning plate to be effectively clamped and positioned.

[0035] Furthermore, after the clamping head 2 is inserted into the positioning plate, the drive motor 8 can be started to drive the main shaft 9 to rotate. The main shaft 9 drives the shaft 6 to rotate through the belt 10, which in turn drives the pressure wheel 7 to rotate. The rotation of the pressure wheel 7 realizes the rolling conveying of the positioning column, reduces the resistance during the movement of the positioning column, and facilitates the insertion and positioning of the positioning column.

[0036] Furthermore, the rotation of the main shaft 9 will drive the push plate 11 to move upward, so that the push plate 11 uses the inclined surface of the inclined push block 13 to push the inclined push block 13 to move towards the positioning plate, thereby causing the inclined push block 13 to push the pressure wheel 7 to move, so that the pressure wheel 7 can generate effective squeezing force with the positioning plate, thereby allowing the positioning plate to be further clamped and improving the stability of the positioning plate transfer process.

[0037] After the positioning plate leaves the position of the clamping roller 7, the drive motor 8 can be turned off, thereby stopping the drive of the clamping roller 7 and keeping the clamping roller 7 in its existing position. Then, the electrorheological fluid inside the fixed box 5 is energized, causing the electrorheological fluid inside the fixed box 5 to change from a liquid state to a solid state, thereby preventing the locking block 16 and the slide bar 15 from moving, thereby fixing the position of the drive shaft 6, and further fixing the position of the clamping roller 7.

[0038] After the positioning plate is installed, it will be blocked by the clamping wheel 7, which prevents the positioning plate from moving outward directly. When it needs to be disassembled, the clamping wheel 7 needs to be moved first to make room for it, so that the positioning plate can be taken out and disassembled smoothly, with accurate and stable positioning.

[0039] When needed, the small adjustment motor 22 can be started to drive the small lead screw 23 to rotate. The rotation of the small lead screw 23 drives the small slider 24 to move laterally, thereby adjusting the position of the clamping head 2. The two clamping heads 2 can be adjusted independently, so the relative position of the two clamping heads 2 can be adjusted slightly, which makes it easier to adapt to the installation of various workpieces and enhances the overall adjustability.

[0040] By starting the large-amplitude adjustment motor 18, the large-amplitude lead screw 19 can be driven to rotate. The rotation of the large-amplitude lead screw 19 will drive the large-amplitude slider 20 to move laterally. Since the large-amplitude slider 20 can drive the two small-amplitude sliders 24 to move at the same time, the overall position can be adjusted while keeping the relative positions of the two clamping heads 2 stable, which facilitates the position adjustment after clamping and positioning.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
