Industrial sewing machine

Abstract

This utility model discloses an industrial sewing machine, including a worktable, a sewing machine head mounted on the top of the worktable, and a transparent baffle mounted on the front end of the sewing machine head via an angle adjustment component. The angle adjustment component includes a mounting base mounted on the front end of the sewing machine head, a rotating shaft rotatably mounted on the mounting base, a transparent baffle mounted on one end of the rotating shaft, and the other end of the rotating shaft connected to one end of a handle via a first elastic element. By turning the handle, the first elastic element can undergo elastic deformation, thereby separating the first tooth block from the toothed ring. After the first tooth block is separated from the toothed ring, rotating the handle can drive the rotating shaft to rotate, which in turn drives the transparent baffle to rotate, thereby adjusting the angle of the transparent baffle. After adjustment, releasing the handle causes the first elastic element to apply force to the handle, causing the first tooth block to mesh with the toothed ring, thus fixing the angle of the transparent baffle. Therefore, the transparent baffle can be adjusted to a suitable angle according to different workers.

Description

Technical Field

[0001] This utility model relates to the field of sewing equipment technology, and in particular to an industrial sewing machine. Background Technology

[0002] Industrial sewing machines are specialized equipment designed for high-efficiency, high-intensity sewing tasks, and are widely used in industries such as clothing, bags, shoes, hats, automotive interiors, and home textiles. Compared to household sewing machines, industrial sewing machines offer higher speeds, greater durability, and more professional sewing capabilities.

[0003] Existing industrial sewing machines typically have a transparent baffle installed at the front of the sewing machine head to block high-speed flying debris such as broken needles, thread ends, and fabric scraps, thus protecting the worker. When sewing, the worker's view is clearest when looking directly at the transparent baffle. However, due to differences in worker height and working posture, the angle of the transparent baffle needs to be adjusted so that the worker can see it directly. However, the transparent baffle is fixed to the sewing machine head with bolts, and its angle cannot be adjusted, thus requiring improvement. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose an industrial sewing machine that solves the technical problem that when workers are sewing, their line of sight is clearest when they look directly at the transparent baffle. However, due to the different heights and working postures of different workers, the angle of the transparent baffle needs to be adjusted so that workers can see the transparent baffle directly. However, the transparent baffle is fixedly installed on the sewing machine head with bolts, and its angle cannot be adjusted.

[0005] To achieve the above-mentioned technical objectives, the present invention provides an industrial sewing machine, including a worktable, a sewing machine head mounted on the top of the worktable, a transparent baffle mounted on the front end of the sewing machine head via an angle adjustment component, the angle adjustment component including a mounting base mounted on the front end of the sewing machine head, a rotating shaft rotatably mounted on the mounting base, a transparent baffle mounted on one end of the rotating shaft, and the other end of the rotating shaft connected to one end of a handle via a first elastic element. A toothed ring is mounted on the side of the mounting base near the handle, and a first toothed block matching the toothed ring is mounted on the handle. By bending the handle, the first elastic element can undergo elastic deformation, thereby separating the first toothed block from the toothed ring. After releasing the handle, the first elastic element applies force to the handle, causing the first toothed block to mesh with the toothed ring.

[0006] Furthermore, two first pin sleeves are installed opposite each other at the connection end between the rotating shaft and the handle bar, and two second pin sleeves are installed opposite each other at the connection end between the handle bar and the rotating shaft. The two first pin sleeves and the two second pin sleeves are connected by the first pin.

[0007] Furthermore, the first elastic element is a first torsion spring, which is sleeved on the first pin and its two ends are respectively connected to the rotating shaft and the handle.

[0008] Furthermore, a fixing block is provided at the connection end between the rotating shaft and the transparent baffle. A T-shaped groove is provided inside the fixing block. A rack is provided on the connection side between the transparent baffle and the rotating shaft. The rack is slidably disposed inside the T-shaped groove. One side of the fixing block is connected to the handle block through a second elastic element. A second tooth block that cooperates with the rack is provided on the handle block. By pressing the handle block, the second elastic element can undergo elastic deformation, thereby separating the second tooth block from the rack. After releasing the handle block, the second elastic element applies force to the handle block, which can make the second tooth block mesh with the rack.

[0009] Furthermore, two third pin sleeves are installed opposite each other on the connecting side of the fixed block and the handle block, and two fourth pin sleeves are installed opposite each other on the side of the handle block and the fixed block. The two third pin sleeves and the two fourth pin sleeves are connected by a second pin.

[0010] Furthermore, the second elastic element is a second torsion spring, which is sleeved on the second pin and its two ends are respectively connected to the fixed block and the handle block.

[0011] The beneficial effects of this utility model include:

[0012] 1. By turning the handle, the first elastic element can undergo elastic deformation, thereby separating the first toothed block from the gear ring. After the first toothed block separates from the gear ring, rotating the handle will drive the rotating shaft to rotate, which in turn drives the transparent baffle to rotate, thereby adjusting the angle of the transparent baffle. After adjustment, releasing the handle will cause the first elastic element to apply force to the handle, which will cause the first toothed block to mesh with the gear ring, thereby fixing the angle of the transparent baffle. Therefore, the transparent baffle can be adjusted to a suitable angle according to different workers.

[0013] 2. Pressing the handle block causes the second elastic element to deform elastically, thereby separating the second toothed block from the rack. This allows the rack to be released, and it can slide inside the T-shaped slot to adjust the height of the transparent baffle. After adjustment, releasing the handle block causes the second elastic element to apply force to the handle block, engaging the second toothed block with the rack to fix the height of the transparent baffle. Therefore, the transparent baffle can be adjusted to a suitable height to effectively block high-speed flying objects such as broken needles, thread ends, and fabric scraps.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] This utility model embodiment provides an industrial sewing machine, such as Figure 1-3 The device includes a workbench 1, with a sewing machine head 2 mounted on top of the workbench 1. A transparent baffle 4 is mounted on the front end of the sewing machine head 2 via an angle adjustment assembly 3. The angle adjustment assembly 3 includes a mounting base 31 mounted on the front end of the sewing machine head 2. A rotating shaft 32 is rotatably mounted on the mounting base 31. The transparent baffle 4 is mounted on one end of the rotating shaft 32, and the other end of the rotating shaft 32 is connected to one end of a handle 34 via a first elastic element 33. A toothed ring 35 is mounted on the side of the mounting base 31 near the handle 34, and a first toothed block 36 matching the toothed ring 35 is mounted on the handle 34. By turning the handle 34, the device can... The first elastic element 33 undergoes elastic deformation, thereby separating the first toothed block 36 from the toothed ring 35. After the first toothed block 36 separates from the toothed ring 35, the handle 34 is rotated, which drives the rotating shaft 32 to rotate. The rotating shaft 32 drives the transparent baffle 4 to rotate, thereby adjusting the angle of the transparent baffle 4. After adjustment, the handle 34 is released, and the first elastic element 33 applies force to the handle 34, which causes the first toothed block 36 to mesh with the toothed ring 35, thereby fixing the angle of the transparent baffle 4. Therefore, the transparent baffle 4 can be adjusted to a suitable angle according to different workers.

[0022] In this embodiment, two first pin sleeves 37 are installed opposite to the connecting end of the rotating shaft 32 and the handle 34, and two second pin sleeves 38 are installed opposite to the connecting end of the handle 34 and the rotating shaft 32. The two first pin sleeves 37 and the two second pin sleeves 38 are connected by a first pin 39. At the same time, the first elastic element 33 is a first torsion spring, which is sleeved on the first pin 39 and its two ends are respectively connected to the rotating shaft 32 and the handle 34. When the handle 34 is turned, the handle 34 can rotate around the connecting end of the handle 34 and the rotating shaft 32, so that the first tooth block 36 separates from the tooth ring 35. When the handle 34 is released, the first torsion spring applies force to the handle 34, so that the first tooth block 36 meshes with the tooth ring 35. The structure is stable and highly reliable.

[0023] In this embodiment, as Figure 4-5 As shown, a fixing block 310 is provided at the connection end between the rotating shaft 32 and the transparent baffle 4. The fixing block 310 has a T-shaped groove inside. A rack 41 is provided on the connection side between the transparent baffle 4 and the rotating shaft 32. The rack 41 slides inside the T-shaped groove. One side of the fixing block 310 is connected to the handle block 312 via a second elastic element 311. The handle block 312 has a second toothed block 313 that engages with the rack 41. By pressing the handle block 312, the second elastic element 311 can undergo elastic deformation, thereby allowing the second toothed block 313 to move. The two-toothed block 313 separates from the rack 41, allowing the rack 41 to be released. Simultaneously, the rack 41 can slide inside the T-shaped slot to adjust the height of the transparent baffle 4. After adjustment, the handle block 312 is released, and the second elastic element 311 applies force to the handle block 312, causing the second toothed block 313 to mesh with the rack 41 to fix the height of the transparent baffle 4. Therefore, the transparent baffle 4 can be adjusted to a suitable height to effectively block high-speed flying objects such as broken needles, thread ends, and fabric scraps.

[0024] In this embodiment, two third pin sleeves 314 are installed opposite to each other on the connecting side of the fixed block 310 and the handle block 312, and two fourth pin sleeves 315 are installed opposite to each other on the side of the handle block 312 and the fixed block 310. The two third pin sleeves 314 and the two fourth pin sleeves 315 are connected by a second pin 316. The second elastic element 311 is a second torsion spring. The second torsion spring is sleeved on the second pin 316 and its two ends are respectively connected to the fixed block 310 and the handle block 312. When the handle block 312 is pressed, the handle block 312 can rotate around the connection between the handle block 312 and the fixed block 310, so that the second tooth block 313 separates from the rack 41. When the handle block 312 is released, the second torsion spring applies force to the handle block 312, so that the second tooth block 313 meshes with the rack 41. The structure is stable and highly reliable.

[0025] This utility model embodiment provides an industrial sewing machine. When a worker is sewing, they can pry the handle 34 to separate the first toothed block 36 from the toothed ring 35. After the first toothed block 36 is separated from the toothed ring 35, the handle 34 can be rotated, which can drive the rotating shaft 32 to rotate. The rotating shaft 32 can drive the transparent baffle 4 to rotate, thereby adjusting the angle of the transparent baffle 4. After adjustment, the handle 34 is released, and the first elastic element 33 applies force to the handle 34, which can make the first toothed block 36 mesh with the toothed ring 35, thereby fixing the angle of the transparent baffle 4. Therefore, the transparent baffle 4 can be adjusted to a suitable angle according to different workers.
