Description

Technical Field

[0001] This utility model relates to the field of sewing machine technology, specifically to a noise reduction structure for the table cover of a template machine and the template machine itself. Background Technology

[0002] A template sewing machine is a fully automated sewing machine that combines garment template CAD software, garment templates, and advanced CNC technology to produce garments using templates. This improves production efficiency and product quality, reduces the technical requirements for skilled workers, and replaces manually operated sewing machines with a more automated, computer-controlled machine. Unlike traditional sewing machines, template sewing machines process mostly larger products, resulting in very large template sewing machines themselves. Therefore, they cannot be used on assembly lines in traditional garment factories. Typically, multiple template sewing machines are placed in a separate room. However, due to the relatively small and enclosed space, the noise from the template sewing machines reflects and radiates within the room, causing significant noise pollution for users. The noise from the shuttle and needle plate is one of the main noise sources of the template sewing machine.

[0003] The area around the shuttle needle plate of the template machine consists of a base, a transmission gear, a shuttle shaft (also called a lower shaft), a shuttle, a table cover, and a needle plate. The shuttle shaft is rotatably installed inside the base. One end of the shuttle is connected to the shuttle in the shuttle cavity, and the other end of the shuttle shaft is connected to the transmission gear in the gear cavity. The table cover covers the entire shuttle shaft. The needle plate is located in the mounting hole on the table cover and is fixedly connected to the base, covering the shuttle. When the shuttle shaft rotates at high speed, the high-speed meshing of the gears will generate a lot of noise. This noise is transmitted to the top of the table cover, causing the template machine to be noisy, which will disturb the user and affect their physical and mental health.

[0004] Therefore, how to reduce the noise of the gear transmission of the template machine has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the purpose of this utility model is to provide a noise reduction structure for the table cover of a template machine in response to the above-mentioned technology.

[0006] The technical solution adopted in this utility model is: a noise reduction structure for the table cover of a template machine, comprising:

[0007] A base, on which a gear cavity and a rotary shuttle cavity are formed;

[0008] A rotary shuttle shaft is installed inside the base, with one end of the rotary shuttle shaft connected to a transmission gear in the gear cavity, and the other end of the rotary shuttle shaft connected to a rotary shuttle in the rotary shuttle cavity;

[0009] A tabletop cover is installed above the base. A grid-like protrusion is formed on the lower surface of the tabletop cover. The grid-like protrusion is located directly above the gear cavity, and the lower surface of the grid-like protrusion is in contact with the upper surface of the base.

[0010] Preferably, the mesh-like protrusions are polygonal protrusions.

[0011] Preferably, the polygonal protrusions are square protrusions or honeycomb protrusions.

[0012] Preferably, the vertical dimension of the mesh-like protrusions is 2-5 mm.

[0013] Preferably, the vertical dimension of the mesh-like protrusions is 3mm.

[0014] Preferably, the mesh-like protrusions are integrally formed on the lower surface of the tabletop cover.

[0015] Preferably, the countertop cover is made of nylon, stainless steel or aluminum alloy.

[0016] The second objective of this utility model is to provide a template machine, including the aforementioned noise reduction structure for the template machine's tabletop cover.

[0017] The beneficial effects of this utility model are:

[0018] This invention features a grid-like protrusion formed on the lower surface of the tabletop cover, with the lower surface of the grid-like protrusion fitting against the upper surface of the base. This allows the grid-like protrusion to divide the lower surface of the tabletop cover into multiple independent areas, thereby blocking air fluctuations and preventing noise transmission, thus effectively blocking the propagation of noise within the gear cavity.

[0032] Examples, such as Figure 1 and Figure 2 As shown, a noise reduction structure for a template machine's table cover includes a base 10, a rotary shaft 20, and a table cover 30. A gear cavity 11 and a rotary shaft cavity 12 are formed on the base 10. The rotary shaft 20 is installed inside the base 10, with one end connected to a transmission gear 40 in the gear cavity 11 and the other end connected to a rotary shuttle 50 in the rotary shaft cavity 12. The table cover 30 is installed above the base 10, and a grid-like protrusion 31 is formed on the lower surface of the table cover 30. The grid-like protrusion 31 is located directly above the gear cavity 11, and its lower surface is in contact with the upper surface of the base 10.

[0033] The present invention has a grid-like protrusion 31 formed on the lower surface of the tabletop cover plate 30, and the lower surface of the grid-like protrusion 31 is attached to the upper surface of the base 10, so that the grid-like protrusion 31 can divide the lower surface of the tabletop cover plate 30 into multiple independent areas, thereby blocking air fluctuations and preventing noise transmission, thus effectively blocking the propagation of noise in the gear cavity 11.

[0034] Specific embodiment 1, such as Figure 1 and Figure 2 As shown, a noise reduction structure for a template machine's table cover includes a base 10, a rotary shaft 20, and a table cover 30.

[0035] The base 10 is arranged in a horizontal direction. A gear cavity 11 and a shuttle cavity 12 are formed at one end of the base 10. The gear cavity 11 and the shuttle cavity 12 are arranged side by side in the base 10, that is, in the horizontal direction, the gear cavity 11 and the shuttle cavity 12 are spaced apart. A transmission gear 40 is provided in the gear cavity 11, and a shuttle 50 is provided in the shuttle cavity 12.

[0036] The rotary shuttle shaft 20 is installed in the base 10 and can rotate around its own axis. The rotary shuttle shaft 20 is arranged in a horizontal direction, and one end of the rotary shuttle shaft 20 extends axially into the gear cavity 11 and is connected to the transmission gear 40 in the gear cavity 11. The other end of the rotary shuttle shaft 20 extends axially into the rotary shuttle cavity 12 and is connected to the rotary shuttle 50 in the rotary shuttle cavity 12.

[0037] The tabletop cover plate 30 is fixedly installed above the base 10. A mounting hole 32 is formed at one end of the tabletop cover plate 30, and a needle plate 60 is installed in the mounting hole 32. The needle plate 60 is located directly above the rotary hook 50. A grid-shaped protrusion 31 is integrally formed on the lower surface of the other end of the tabletop cover plate 30. The grid-shaped protrusion 31 is located directly above the gear cavity 11, and the grid-shaped protrusion 31 extends downward in the vertical direction until the lower surface of the grid-shaped protrusion 31 is in contact with the upper surface of the base 10.

[0038] Specifically, the vertical dimension of the mesh-like protrusion 31 is 2-5mm, that is, the vertical extension dimension of the mesh-like protrusion 31 is 2-5mm. Preferably, the vertical dimension of the mesh-like protrusion 31 is 3mm.

[0039] The grid-like protrusions 31 are polygonal protrusions, preferably square protrusions or honeycomb protrusions.

[0040] The countertop cover 30 is made of nylon, stainless steel, or aluminum alloy.

[0041] An embodiment of a template machine includes the aforementioned noise reduction structure for the table cover of a template machine.

[0042] The working principle of the noise reduction structure for the tabletop cover of this utility model is as follows:

[0043] This invention divides the lower surface of the tabletop cover into multiple independent regions by forming a grid-like ridge on the lower surface of the tabletop cover. The ridges between the regions can block air fluctuations and prevent noise transmission, effectively blocking the propagation of gear transmission noise in the gear cavity. At the same time, the grid-like ridge can increase the local stiffness of the tabletop cover, significantly improving the surface modes of the tabletop cover, making the tabletop cover less responsive to vibration and noise, less likely to be excited by gear vibration, and less likely to resonate.

[0044] Compared with the prior art, this application has at least the following beneficial technical effects:

[0045] This invention significantly reduces the overall noise of the template machine without altering the sewing mechanism, greatly reducing the transmission of gear transmission noise within the gear cavity to the user and effectively minimizing noise disturbance.

[0046] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
