Description

Technical Field

[0001] This utility model belongs to the field of fabric processing technology, specifically an industrial sewing machine for processing large, thick materials. Background Technology

[0002] Industrial sewing machines are sewing machines used in sewing factories or other industrial sectors for mass production of sewing workpieces. Their main characteristics include high speed and efficiency, complex structure, and diverse functions. Industrial sewing machines often need to sew large, thick materials. The core features of industrial sewing machines for large, thick material processing are powerful performance, robust structure, and stable feeding, easily handling the sewing needs of multi-layered thick or hard materials. However, existing industrial sewing machines for large, thick material processing often encounter difficulties when pushing the fabric to the sewing machine needle. Because some fabric is too thick, it is difficult to press it into the needle, requiring workers to manually press the fabric under the needle, which puts their hands close to the needle, increasing the risk of accidental injury and increasing labor costs. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides an industrial sewing machine for large-scale thick material processing, which solves the problem that when the existing industrial sewing machines for large-scale thick material processing push the fabric to the sewing machine needle, some of the fabric is too thick to be pressed into the needle, and the operator needs to manually press the fabric under the needle, which makes the operator's hand close to the needle, which is easy to cause accidental injury to the operator and increases labor costs.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A large-scale industrial sewing machine for processing thick materials includes a processing table. A sewing machine body is provided on the top of the processing table. An installation plate is fixedly installed on one side of the sewing machine body. Sliding grooves are provided through both sides of the installation plate. A connecting frame is slidably connected to the top surface of the installation plate. A connecting rod is fixedly installed at the bottom of the connecting frame and is slidably connected through the sliding groove. A connecting block is fixedly installed in the middle of the connecting rod. A locking block is slidably connected through both ends of the connecting rod. Two limiting sliding grooves are symmetrically provided on the top of the installation plate and the connecting frame. A connecting strip is fixedly connected to the top of the locking block and slides through the installation plate and the connecting frame inside the limiting sliding groove. A telescopic spring is sleeved on the surface of the connecting rod between the locking block and the connecting block.

[0005] The mounting plate has several symmetrical card interfaces on both sides inside, and the positions of the card interfaces correspond to the protrusions on the surface of the card block. A movable plate is fixedly connected to one side of the connecting block through the mounting plate. Two limiting posts are slidably connected through the top of the movable plate. The bottom of the two limiting posts is fixedly connected to the mounting block. A compression spring is sleeved on the surface of the limiting posts between the movable plate and the mounting block. A roller is rotatably connected to the bottom of the mounting block through a rotating shaft.

[0006] As a further embodiment of this utility model: two T-shaped slide bars are fixedly installed at the bottom of the sewing machine body, and two through grooves are provided on the top of the processing table, with the T-shaped slide bars sliding inside the through grooves.

[0007] As a further embodiment of this utility model: the bottom of the processing table is provided with a base plate, and the bottom of the two T-shaped slide bars passes through the processing table and is fixedly connected to the base plate.

[0008] As a further embodiment of this utility model: a connecting plate is fixedly connected to one end of the base plate, and the connecting plate slides close to one side of the processing table.

[0009] As a further embodiment of this utility model: the surface of the connecting plate is threaded with a rotating bolt, and the processing table is provided with a snap-fit ​​groove on one side of the connecting plate.

[0010] As a further embodiment of this utility model: the end of the rotating bolt near the processing table is rotatably connected to a rubber pressure block via a pin, and the rubber pressure block is tightly attached to the inside of the snap-fit ​​groove.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This large-scale industrial sewing machine for processing thick materials, by setting up a connecting frame, a pressure spring, and a roller, pushes the thick material close to the needle feet of the sewing machine body. When the thick material is pushed, the two connecting strips are pulled to slide inside the limit slide groove, causing the locking block to compress the telescopic spring. After pushing the connecting frame down to the appropriate position, the connecting strips are released, causing the telescopic spring to rebound and push the locking block to lock in the locking interface at the appropriate position. The distance between the roller and the thick material is adjusted, and the pressure spring is pressed against the top of the mounting block, so that the roller presses the thick material tightly, making it easier to enter the needle feet of the sewing machine body and avoiding accidental injury to the operator's hands near the needle feet.

[0013] 2. This large-scale industrial sewing machine for processing thick materials, by setting a rotating bolt and a locking groove, allows for the loosening of the rotating bolt when processing thick materials with a large width, pulling the sewing machine body to move on the processing table surface. At this time, the T-shaped slide bar moves inside the through groove to prevent the sewing machine body from deflecting. After moving to the appropriate position, the rotating bolt is tightened to make the rubber pressure block stick tightly inside the locking groove, thereby fixing the position of the sewing machine body and completing the adjustment of the position of the sewing machine body, preventing the edge of the thick material from exceeding the processing table and touching the ground, thus preventing it from falling.

[0018] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0019] like Figure 1-3 As shown, this utility model provides a technical solution: a large-scale industrial sewing machine for processing thick materials, including a processing table 1, a sewing machine body 2 on the top of the processing table 1, a mounting plate 3 fixedly installed on one side of the sewing machine body 2, sliding grooves 4 penetrating on both sides of the mounting plate 3, a connecting frame 5 slidably connected to the top surface of the mounting plate 3, a connecting rod 6 fixedly installed at the bottom inside the connecting frame 5, and the connecting rod 6 slidably connected inside the sliding groove 4, a connecting block 7 fixedly installed in the middle of the connecting rod 6, and locking blocks 8 slidably connected to both ends of the connecting rod 6, the tops of the mounting plate 3 and the connecting frame 5 being symmetrical. Two limiting grooves 23 are provided. A connecting strip 24 is fixedly connected to the top of the snap-fit ​​block 8. The connecting strip 24 passes through the mounting plate 3 and the connecting frame 5 and slides inside the limiting groove 23. A telescopic spring 9 is sleeved on the surface of the connecting rod 6 between the snap-fit ​​block 8 and the connecting block 7. With the telescopic spring 9, when the connecting frame 5 is moved, the snap-fit ​​block 8 slides towards the connecting block 7 to compress the telescopic spring 9 and disengages from the snap-fit ​​interface 10. When it moves to the next snap-fit ​​interface 10, the telescopic spring 9 rebounds and the protrusion on the surface of the snap-fit ​​block 8 engages with the snap-fit ​​interface 10, thus completing the height adjustment of the moving plate 11.

[0020] The mounting plate 3 has several symmetrical card slots 10 on both sides inside, and the positions of the card slots 10 correspond to the protrusions on the surface of the card block 8. A movable plate 11 is fixedly connected to one side of the connecting block 7 through the mounting plate 3. Two limiting posts 12 are slidably connected through the top of the movable plate 11. The bottom of the two limiting posts 12 is fixedly connected to the mounting block 14. A compression spring 13 is sleeved on the surface of the limiting post 12 between the movable plate 11 and the mounting block 14. The bottom of the mounting block 14 is rotatably connected to a roller 15 through a rotating shaft. With the limiting posts 12, the roller 15 pushes up the limiting posts 12 and slides on the surface of the movable plate 11, so that the roller 15 will not deviate when moving up and down.

[0021] Two T-shaped slide bars 16 are fixedly installed at the bottom of the sewing machine body 2. Two through grooves 17 are provided on the top of the processing table 1, and the T-shaped slide bars 16 slide inside the through grooves 17. By providing the T-shaped slide bars 16, the sewing machine body 2 slides inside the through grooves 17 through the T-shaped slide bars 16, making it less likely for the sewing machine body 2 to deflect when moving.

[0022] The bottom of the processing table 1 is provided with a base plate 18, and the bottom of the two T-shaped slide bars 16 pass through the processing table 1 and are fixedly connected to the base plate 18. A connecting plate 20 is fixedly connected to one end of the base plate 18, and the connecting plate 20 slides close to one side of the processing table 1. By providing the base plate 18, the base plate 18 is fixedly connected to the T-shaped slide bars 16 and close to the bottom of the processing table 1, so that the sewing machine body 2 is not easy to detach from the processing table 1.

[0023] A rotating bolt 21 is threaded through the surface of the connecting plate 20. The processing table 1 is located on one side of the connecting plate 20 and has a snap-fit ​​groove 19. The end of the rotating bolt 21 near the processing table 1 is rotatably connected to a rubber pressure block 22 via a pin. The rubber pressure block 22 is tightly attached to the inside of the snap-fit ​​groove 19. With the rubber pressure block 22, when the sewing machine body 2 moves to the appropriate position, the rotating bolt 21 is tightened so that the rubber pressure block 22 is tightly attached to the inside of the snap-fit ​​groove 19, thereby fixing the position of the sewing machine body 2.

[0024] The working principle of this utility model is as follows:

[0025] Loosen the rotating bolt 21 and adjust the position of the sewing machine body 2 on the top of the processing table 1 according to the width of the thick material. At this time, the T-shaped slide bar 16 slides inside the through groove 17, causing the base plate 18 to drive the connecting plate 20 to move on the surface of the snap-fit ​​groove 19. After confirming the position of the sewing machine body 2, tighten the rotating bolt 21 to make the rubber pressure block 22 stick tightly to the inside of the snap-fit ​​groove 19, fix the position of the sewing machine body 2, and prevent the thick material from being too wide and falling to the ground beyond the edge of the processing table 1. Then push the thick material closer to the needle of the sewing machine body 2 and pull the two connecting bars 2. 4. The sliding action moves the snap-fit ​​block 8 to compress the telescopic spring 9, and then pushes the connecting frame 5 downward to the appropriate position. The two limiting grooves 23 are released, causing the telescopic spring 9 to rebound. The protrusion on the surface of the snap-fit ​​block 8 is snapped into the snap-fit ​​interface 10, thereby causing the connecting block 7 to move the moving plate 11 on the surface of the mounting plate 3, causing the roller 15 to press against the surface of the thick material. The limiting post 12 slides on the surface of the moving plate 11, causing the compression spring 13 to compress, causing the roller 15 to press the thick material, which facilitates the entry of the thick material into the needle, while preventing the worker's hand from getting close to the needle and reducing the risk of worker injury.
