Description

Technical Field

[0001] This invention relates to the technical field of sewing machine frames, specifically to an integrated molding device for the back beam of a sewing machine frame. Background Technology

[0002] A sewing machine is a machine that uses one or more sewing threads to create one or more stitches on fabric, allowing one or more layers of fabric to interweave or sew together. A sewing machine consists of various components, including a sewing machine frame, which not only supports the machine but also houses the pedals for providing power. Back beams are also installed between the sewing machine frames to support the spacing between the side supports.

[0003] Existing technology requires manual shearing of the sheet metal during back beam production. The sheared sheet metal is then placed into a stamping device for punching, and a chamfering device is used to change the shape of the sheet metal. In mass production, manual assistance and handling are required, which increases labor intensity and costs. Furthermore, because the sheared edges of the sheet metal are relatively sharp, they can easily cause injury to workers during handling. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to provide an integrated molding device for the back beam of a sewing machine frame, so as to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] An integrated forming device for a sewing machine frame back beam includes a winding machine, a processing table, and a roll of material. A rotating shaft is provided on one side of the winding machine. Four arc-shaped plates are connected to the outer wall of the rotating shaft via connecting rods. The inner ring of the roll of material is fitted onto the four arc-shaped plates. A limiting frame is installed on each of the arc-shaped plates on both sides of the roll of material. A guide frame, a stamping assembly, a pressing frame, a beveling assembly, and a cutting assembly are sequentially arranged on the upper surface of the processing table. The end of the roll of material passes through the guide frame, the stamping assembly, the pressing frame, the beveling assembly, and the cutting assembly sequentially. A moving assembly is provided on one side of the stamping assembly and the cutting assembly on the upper surface of the processing table. The moving assembly is used to move the stamping assembly and the cutting assembly to form a relatively stationary position relative to the roll of material, facilitating stamping and cutting. A driving device is provided on one side of the beveling assembly on the upper surface of the processing table. The beveling assembly includes several beveling rollers, with the length of the beveling rollers decreasing sequentially on the side furthest from the stamping assembly.

[0007] Specifically, in this technical solution, the two ends of the four connecting rods are respectively movably connected to the outer wall of the rotating shaft and the inner walls of the four arc-shaped plates via the rotating shaft. A positioning block is welded to the outer wall of one of the arc-shaped plates. The limiting frame is triangularly arranged.

[0011] Specifically, in this technical solution, the clamping frame has two parts located at both ends of the chamfering assembly. The clamping frame consists of two symmetrically arranged support plates. A fixed roller is provided at the bottom between the two support plates. Each of the two support plates has a movable cavity, and each of the two movable cavities has a movable plate. A pressure roller is rotatably installed between the two movable plates. A second threaded rod is threadedly installed on the top of each of the two movable plates. A rotating rod is connected to the top of each of the two second threaded rods. The top of each of the two rotating rods extends out of the top of the support plate and is connected to a rotating plate. A limiting plate is connected to the side of each of the two movable plates away from the pressure roller.

[0012] Specifically, in this technical solution, the bottom ends of both support plates are bolted to the upper surface of the processing table, both ends of the fixed roller are rotatably connected to the support plates, both movable plates are slidably connected to the moving cavity, the two second threaded rods are welded to the rotating rods, both rotating rods are welded to the rotating plate, both limiting plates are fixedly connected to the movable plates, the length of the two limiting plates is the same as the length of the support plates, and both sides of the two limiting plates are fixedly connected to the support plates by bolts.

[0013] Specifically, the beveling assembly consists of a mounting frame and several rollers and beveling rollers. The mounting frame is bolted to the upper surface of the processing table. Grooves are provided on both ends of the mounting frame at the several beveling rollers. Mounting blocks are movably installed in the several grooves. A third threaded rod is threaded into the top of each of the several mounting blocks. Pressure plates are bolted to the top of the mounting frame at the several grooves. Handles are welded to the tops of the several third threaded rods through the pressure plates. The several rollers are located below the beveling rollers.

Support rods are vertically positioned at the four corners of the U-shaped block. A top plate is fixedly mounted at the top of each of the four support rods. A hydraulic cylinder is bolted to the upper surface of the top plate. A cutter is fixedly connected to the actuating end of the hydraulic cylinder through the top plate. The cutter is inserted into the U-shaped block and positioned above the forming back beam.

[0015] The two moving components include forward and reverse motors bolted to the upper surface of the processing table. The output ends of the two forward and reverse motors are fixedly connected to lead screws. The execution ends of the two lead screws are threaded with moving blocks. The two moving blocks are fixedly connected to the side wall of the horizontal plate of the stamping component and the side wall of the bottom plate of the cutting component, respectively. The ends of the two lead screws away from the forward and reverse motors are rotatably inserted with support seats. The two support seats are bolted to the upper surface of the processing table.

[0016] In summary, the present invention has the following advantages: This application enables the one-piece molding process for the back beam of a sewing machine frame during mass production. The process does not require manual assistance or handling, reducing the labor intensity of workers, effectively reducing labor costs, and increasing production speed.

[0017] The winding machine installs the roll material used for producing the back beam, and restricts both sides of the roll material by fixing it with a limiting frame to prevent the roll material from shifting and falling off the curved plate during the unwinding process. At the same time, the limiting frame can be fixed without the need to use tools to tighten the bolts, making the installation faster.

[0018] After the fixed roll material is pulled out, the sheet material is guided by the guide rollers on the guide frame and enters between the stamping base plate and the stamping plate of the stamping assembly. While the sheet material is moving, in order to ensure the stability of the stamping, the moving assembly is started. The moving assembly works and its screw rotates, which causes the moving block to drive the horizontal plate to move along the first slide rail. The moving speed is the same as the moving speed of the sheet material. Then the stamping cylinder works to make the pressure plate move down to perform the stamping operation on the sheet material.

[0019] After stamping, the sheet metal enters the chamfering assembly between the pressure rollers and the fixed rollers of the clamping frame. At this time, the drive device is started to make several chamfering rollers rotate synchronously. As the length of the chamfering rollers becomes shorter one by one, the side edges of the sheet metal are chamfered to complete the forming operation of the back beam.

[0020] After the formed board passes through the U-shaped block of the cutting component, when the length of the board reaches the specified cutting length, the moving component starts its screw to rotate, causing the moving block to drive the base plate to move along the second slide rail. At the same time, the hydraulic cylinder works to drive the cutter downward, so that the cutter moves along the cutting surface of the U-shaped block. The bottom of the cutter contacts the board and cuts it. The cut board is then manually picked up and placed into the collection box. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of the present invention will now be described.

[0030] Example

[0031] All electrical components in this application are controlled by conventional controllers, and the drive device has an existing structure for driving the rotation of several beveling rollers 603 in the beveling assembly 6.

[0032] Please see Figure 1As shown, an integrated molding device for a sewing machine frame back beam includes a winding machine 1, a processing table 3, and a roll of material 9. A rotating shaft 101 is provided on one side of the winding machine 1. Four arc-shaped plates 102 are connected to the outer wall of the rotating shaft 101 via connecting rods 103. The inner ring of the roll of material 9 is fitted onto the four arc-shaped plates 102. A limiting frame 2 is installed on both sides of one arc-shaped plate 102. A guide frame 301, a stamping assembly 4, a pressing frame 5, a chamfering assembly 6, and a cutting assembly 8 are sequentially arranged on the upper surface of the processing table 3. The roll of material 9... The end passes through the guide frame 301, the stamping assembly 4, the clamping frame 5, the chamfering assembly 6 and the cutting assembly 8 in sequence. The upper surface of the processing table 3 is provided with a moving assembly 10 on one side of the stamping assembly 4 and the cutting assembly 8. The moving assembly 10 is used to move the stamping assembly 4 and the cutting assembly 8 to form a relatively stationary position with the roll material, which is convenient for stamping and cutting. The upper surface of the processing table 3 is provided with a driving device 7 on one side of the chamfering assembly 6. The chamfering assembly 6 includes several chamfering rollers 603. The length of the several chamfering rollers 603 on the side away from the stamping assembly 4 decreases sequentially.

[0033] The two moving components 10 include forward and reverse motors 1001 that are bolted to the upper surface of the processing table 3. The output ends of the two forward and reverse motors 1001 are fixedly connected to lead screws 1002. The execution ends of the two lead screws 1002 are threaded with moving blocks 1003. The two moving blocks 1003 are fixedly connected to the side wall of the horizontal plate 403 of the stamping component 4 and the side wall of the bottom plate 803 of the cutting component 8, respectively. The ends of the two lead screws 1002 away from the forward and reverse motors 1001 are rotatably inserted with support seats 1004. The two support seats 1004 are bolted to the upper surface of the processing table 3.

[0034] During the mass production of sewing machine frame back beams, workers place the roll material 9 used for back beam production onto the rotating shaft 101 of the winding machine 1 using a transport vehicle. The outer wall of the curved plate 102 is adjusted to abut against the inner wall of the roll material 9 to complete the installation. Then, two limiting frames 2 are quickly fixed onto the curved plate 102, positioning them on either side of the roll material 9 to prevent it from detaching from the winding machine 1. After being fixed, the sheet material at the traction point of the roll material 9 passes between the guide rollers in the guide frame 301 and enters the stamping assembly 4, pressing frame 5, edge-trimming assembly 6, and cutting assembly 8. The winding machine 1 causes the sheet material 9 to move slowly. When passing the stamping assembly 4, a moving component 10 connected to the stamping assembly 4 operates, and the forward and reverse motor 1001 starts, driving the lead screw 1. 002 rotates, and the rotating lead screw 1002 causes the moving block 1003 to drive the stamping component 4 to move. The moving speed is the same as the moving speed of the sheet metal to achieve relative stillness. At this time, the stamping component 4 works to stamp the sheet metal below. The stamped sheet metal enters the chamfering component 6 stably under the action of the clamping frame 5. At this time, the driving device 7 drives the chamfering component 6 to work and chamfer the sheet metal to complete the back beam forming. The formed sheet metal enters the cutting component 8 stably under the action of another clamping frame 5. When the length of the sheet metal reaches the specified cutting length, the moving component 10 connected to the cutting component 8 works. The principle is as above, driving the cutting component 8 to move relatively still with the sheet metal and cut it. The cut sheet metal is picked up manually and placed into the collection box.

[0035] This enables the integrated molding process for mass production of sewing machine frame back beams. The process is mechanically transmitted, eliminating the need for manual operation and handling, thus reducing the labor intensity of workers, effectively lowering labor costs, increasing production speed, and avoiding risks to workers' hands.

[0036] Please see Figure 5-6As shown, the two ends of the four connecting rods 103 are movably connected to the outer wall of the rotating shaft 101 and the inner walls of the four arc-shaped plates 102 via the rotating shaft. A positioning block 1021 is welded to the outer wall of one arc-shaped plate 102. The limiting frame 2 is triangularly arranged. A fixing block 201 is welded to the inner wall of the limiting frame 2 near the bottom of the arc-shaped plate 102. A matching positioning through groove 202 is opened at the bottom of the limiting frame 2 at the positioning block 1021. A cavity 2011 is opened in the fixing block 201. The positioning block 1021 passes through the positioning through groove 202 and is inserted into the cavity 2011. Slots 1022 and fixing grooves 1024 are opened at the end of the positioning block 1021 and its two side walls, respectively. The inner wall of the cavity 2011 is welded at the slot 1022. The device is equipped with a plug 2012. A magnet 1023 is provided in the slot 1022 and magnetically connected to the plug 2012. Square through slots 2013 are provided on both sides of the fixing block 201. A first threaded rod 2015 is vertically provided in each of the two square through slots 2013. A sleeve 2014 is threaded onto the bottom end of each of the two first threaded rods 2015. The outer wall of each sleeve 2014 is in contact with the inner wall of the square through slot 2013 and is slidably connected. The bottom end of each sleeve 2014 is inserted into the fixing slot 1024. A rotating seat 2017 is fixed on the outer wall of the fixing block 201 at the square through slot 2013. A handle 2016 is welded to the top of each of the two first threaded rods 2015 through the rotating seat 2017.

[0037] When installing the limiting frame 2, the worker places the bottom of the limiting frame 2 into the outer wall of the arc plate 102, so that the positioning block 1021 is inserted into the cavity 2011 from the positioning through groove 202. The slot 1022 opened at the end of the positioning block 1021 fits onto the insert block 2012. The magnet 1023 magnetically attracts the insert block 2012 for auxiliary fixation. At this time, the worker manually rotates the handle 2016. The handle 2016 drives the first threaded rod 2015 to rotate on the rotating seat 2017. The rotating first threaded rod 2015 causes the sleeve 2014 to move into the cavity 2011 along the square through groove 2013. The end of the moving sleeve 2014 is inserted into the fixing groove 1024 to fix the positioning block 1021. Thus, the installation can be fixed without the need to use tools to tighten the bolts, making the installation faster.

[0038] Please see Figure 1-2As shown, the stamping assembly 4 includes first slide rails 401 symmetrically arranged on the processing table 3. Multiple first slide blocks 402 are slidably mounted on each of the two first slide rails 401. A horizontal plate 403 is mounted on each of the multiple first slide blocks 402. Guide rods 4031 are vertically arranged at the four corners of the upper surface of the horizontal plate 403. Moving plates 406 are slidably mounted on each of the four guide rods 4031. A stamping base plate 404 is located at the center of the upper surface of the horizontal plate 403. A stamping plate 405 is located above the stamping base plate 404. A fixing plate 407 is mounted on the top of each of the four guide rods 4031. A stamping cylinder 408 is symmetrically installed at the center of the upper surface of the fixed plate 407. Two first slide rails 401 are bolted to the processing table 3. The horizontal plate 403 is bolted to multiple first slide blocks 402. The bottom ends of four guide rods 4031 are fixedly connected to the horizontal plate 403. The stamping base plate 404 is bolted to the horizontal plate 403. Two stamping cylinders 408 are connected to the fixed plate 407 by bolts. The actuating ends of the two stamping cylinders 408 penetrate the fixed plate 407 and are fixedly connected to the upper surface of the moving plate 406. The stamping plate 405 is connected to the lower surface of the moving plate 406.

[0039] Two clamping frames 5 are provided, located at opposite ends of the chamfering assembly 6. The pressure rollers 503 in the two clamping frames 5 have different shapes. The clamping frame 5 is composed of two symmetrically arranged support plates 501. A fixed roller 502 is provided at the bottom between the two support plates 501. Each support plate 501 has a movable cavity 5011, and each movable cavity 5011 has a movable plate 504. A pressure roller 503 is rotatably installed between the two movable plates 504. A second threaded rod 505 is threadedly installed on the top of each of the two movable plates 504. A rotating rod 506 is connected to the top of each of the two second threaded rods 505. The top of each of the two rotating rods 506 protrudes from the top of the support plate 501 and is connected to... The rotating plate 507 and the two movable plates 504 are each connected to a limiting plate 508 on the side away from the pressure roller 503. The bottom ends of the two support plates 501 are bolted to the upper surface of the processing table 3. The two ends of the fixed roller 502 are rotatably connected to the support plates 501. The two movable plates 504 are slidably connected to the moving cavity 5011. The two second threaded rods 505 are welded to the rotating rods 506. The two rotating rods 506 are welded to the rotating plate 507. The two limiting plates 508 are fixedly connected to the movable plates 504. The length of the two limiting plates 508 is the same as the length of the support plates 501, and both sides of the two limiting plates 508 are fixedly connected to the support plates 501 by bolts.

[0040] The horizontal plate 403 in the stamping assembly 4 moves along the moving block 1003. The horizontal plate 403 drives the first slide block 402 to move along the first slide rail 401. The moving speed is the same as the moving speed of the sheet metal. At the same time, the stamping cylinder 408 works. Its actuator pushes the moving plate 406 to move down along the guide rod 4031. The moving plate 406 moves down and drives the stamping plate 405 to move down, so that the stamping plate 405 performs a stamping operation on the sheet metal.

[0041] When the stamped sheet passes through the clamping frame 5, the operator can use a wrench to rotate the rotating plate 507. The rotating plate 507 drives the second threaded rod 505 to rotate via the rotating rod 506. The rotating second threaded rod 505 causes the movable plate 504 to move vertically along the moving cavity 5011. The moving movable plate 504 drives the pressure roller 503 to move, thereby adjusting the distance between the pressure roller 503 and the fixed roller 502, changing the degree of compression on the sheet. After determining the distance, the bolts are tightened using tools to fix the limiting plate 508 and the support plate 501.

[0042] Please see Figure 1 and Figure 4 As shown, the chamfering assembly 6 consists of a mounting frame 601, several rollers 602, and chamfering rollers 603. The mounting frame 601 is bolted to the upper surface of the processing table 3. Grooves 6011 are provided on both ends of the mounting frame 601 at the ends of the several chamfering rollers 603. Mounting blocks 6012 are movably installed in the several grooves 6011. Third threaded rods 6013 are threaded into the top of the several mounting blocks 6012. Pressure plates 6014 are bolted to the top of the mounting frame 601 at the several grooves 6011. Handles 604 are welded to the top of the several third threaded rods 6013 through the pressure plates 6014. Several rollers 602 are located below the chamfering rollers 603. Both ends of the several rollers 602 are rotatably connected to the mounting frame 601. Both ends of the several chamfering rollers 603 are rotatably connected to the mounting blocks 6012. The length of the several chamfering rollers 603 gradually decreases.

[0043] Several beveling rollers 603 in the beveling assembly 6 rotate synchronously under the drive of the drive device 7, pushing the board to move while gradually beveling its edges. The third threaded rod 6013 can be rotated by rotating the handle 604. The second threaded rod 6013 causes the pressure plate 6014 to move vertically along the groove 6011. The moving pressure plate 6014 can drive the beveling rollers 603 to move, thereby adjusting the distance between the beveling rollers 603 and the lower roller shaft 602 and changing the beveling depth of the board.

[0044] Please see Figure 1 and Figure 3As shown, the cutting assembly 8 includes second slide rails 801 symmetrically mounted on the processing table 3. Second slide blocks 802 are slidably mounted on both second slide rails 801. Base plates 803 are mounted on multiple second slide blocks 802. A support plate 804 is bolted to the center of the upper surface of the base plate 803. An inverted U-shaped block 809 is mounted on the upper surface of the support plate 804. Support rods 805 are vertically positioned at the four corners of the U-shaped block 809. A top plate 806 is fixedly mounted at the top of each of the four support rods 805. A hydraulic cylinder 807 is bolted to the upper surface of the top plate 806. A cutter 808 is fixedly connected to the actuating end of the hydraulic cylinder 807 through the top plate 806. The cutter 808 is inserted into the U-shaped block 809 and positioned above the forming back beam. A detector is provided on the outer wall of the U-shaped block 809 to detect the length of the passing sheet material and thus determine the cutting length.

[0045] When cutting the formed sheet material, after the detector detects that the length of the sheet material has reached the required length, the controller controls the moving component 10 connected to the cutting component 8 to work. The forward and reverse motor 1001 drives the lead screw 1002 to rotate, the lead screw 1002 drives the moving block 1003 to move, the moving block 1003 drives the connected base plate 803 to move, and the base plate 803 drives the second slide block 802 to slide along the second slide rail 801. After the base plate 803 moves, the top plate 806 and the U-shaped block 809 installed above it move accordingly. The U-shaped block 809 moves with the sheet material to achieve relative stillness. At this time, the hydraulic cylinder 807 works and its actuator pushes the cutter 808 down. The cutter 808 moves down along the inner wall of the U-shaped block 809 to cut the sheet material below.

[0046] The working principle of this invention is as follows: During the mass production of sewing machine frame back beams, workers place the roll material 9 used for back beam production onto the rotating shaft 101 of the winding machine 1 using a transport vehicle. The arc-shaped plate 102 is adjusted by regulating the tilt angle of the connecting rod 103, ensuring its outer wall abuts against the inner wall of the roll material 9 for installation. Then, two limiting frames 2 are quickly fixed onto one arc-shaped plate 102. The worker then contacts the bottom of the limiting frame 2 against the outer wall of the arc-shaped plate 102, causing the positioning block 102 to engage. 1. The positioning block 1021 is inserted into the cavity 2011 through the positioning slot 202. The slot 1022 at the end of the positioning block 1021 fits onto the insert block 2012. The magnet 1023 magnetically attracts the insert block 2012 for auxiliary fixation. At this time, the operator manually rotates the handle 2016. The handle 2016 drives the first threaded rod 2015 to rotate on the rotating seat 2017. The rotation of the first threaded rod 2015 causes the sleeve 2014 to move into the cavity 2011 along the square through slot 2013. The end of the sleeve 2014 is inserted into the fixing groove 1024 to fix the positioning block 1021. After fixing, the sheet material at the traction point of the coil 9 passes between the guide rollers set in the guide frame 301 and enters the stamping assembly 4, the pressing frame 5, the chamfering assembly 6 and the cutting assembly 8. The coil 9 is slowly moved by the action of the winding machine 1. When passing the stamping assembly 4, a moving assembly 10 connected to the stamping assembly 4 works, and the forward and reverse motor 1001 starts to drive the lead screw 1002 to rotate. The lead screw 1002 causes the moving block 1003 to move the stamping assembly 4. The horizontal plate 403 in the stamping assembly 4 moves with the moving block 1003. The horizontal plate 403 drives the first slide block 402 to move along the first slide rail 401. The moving speed is the same as the moving speed of the sheet metal. At the same time, the stamping cylinder 408 works. Its actuator pushes the moving plate 406 to move down along the guide rod 4031. The moving plate 406 moves down and drives the stamping plate 405 to move down, so that the stamping plate 405 performs a stamping operation on the sheet metal.

[0047] After stamping, the sheet metal is stably fed into the chamfering assembly 6 under the action of the clamping frame 5. At this time, the drive device 7 drives the chamfering assembly 6 to work. Several chamfering rollers 603 in the chamfering assembly 6 rotate synchronously under the drive of the drive device 7, pushing the sheet metal to move while gradually chamfering its edges to complete the formation of the back beam. After the formed sheet metal is stably fed into the cutting assembly 8 under the action of another clamping frame 5. After the detector detects that the length of the sheet metal has reached the required value, the controller controls the moving assembly 10 connected to the cutting assembly 8 to work. The forward and reverse motors 1001 drive the lead screw 10 02. Rotation causes the lead screw 1002 to move the moving block 1003, which in turn moves the connected base plate 803. The base plate 803 then moves the second slide block 802 along the second slide rail 801. After the base plate 803 moves, the top plate 806 and U-shaped block 809 mounted above it move accordingly. The U-shaped block 809 moves with the plate to achieve relative stillness. At this time, the hydraulic cylinder 807 works, and its actuator pushes the cutter 808 downward. The cutter 808 moves down along the inner wall of the U-shaped block 809 to cut the plate below. The cut plate is then manually removed and placed into a collection box.
