Description
Technical Field
[0001] This utility model relates to the field of sewing machine technology, specifically to a noise reduction structure for the upper guide plate position 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 inner liner of the shuttle rubs and collides with the shuttle frame, generating a large and uncomfortable noise. This noise is transmitted to the table cover, causing the template machine to be noisy, disturbing the user and affecting their physical and mental health.
[0004] Therefore, how to reduce the noise of the rotary hook 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 position of the guide plate on the rotary shuttle of a template machine, which addresses the above-mentioned technical problems.
[0006] The technical solution adopted in this utility model is: a noise reduction structure for the upper guide plate position of a template machine, comprising:
[0007] A base, wherein a rotary shaft is provided inside the base;
[0008] A rotary shuttle, wherein the rotary shuttle is disposed in a rotary shuttle cavity at one end of the base, and the rotary shuttle is connected to one end of the rotary shuttle shaft;
[0009] A tabletop cover is disposed above the base, and the tabletop cover has mounting holes formed thereon, the mounting holes being located directly above the rotary hook;
[0010] A needle plate, wherein the needle plate is disposed in a mounting hole;
[0011] An annular sealing gasket is fitted around the periphery of the needle plate and clamped between the needle plate and the table cover plate.
[0012] Preferably, a lower positioning surface is formed in the inner cavity of the annular sealing gasket, and an upper positioning surface that mates with the lower positioning surface is formed on the needle plate.
[0013] Preferably, the annular sealing gasket includes a horizontal sealing portion and a vertical buffer portion, the vertical buffer portion being fixedly connected to the bottom end of the horizontal sealing portion, and the inner diameter of the vertical buffer portion being smaller than the inner diameter of the horizontal sealing portion, so that a lower positioning surface is formed in the inner cavity of the annular sealing gasket.
[0014] Preferably, the needle plate includes an upper plate and a lower plate that are fixedly connected. The lower plate is located directly below the upper plate, and the radial dimension of the upper plate is larger than that of the lower plate, so as to form an upper positioning surface that mates with the lower positioning surface on the periphery of the needle plate.
[0015] Preferably, the annular sealing gasket is made of nitrile rubber.
[0016] Preferably, the mounting hole includes an upper section and a lower section that are vertically connected, and the radial dimension of the upper section is greater than the radial dimension of the lower section, so that a stop surface that matches the vertical buffer portion is formed in the inner cavity of the mounting hole.
[0017] Preferably, the top of the upper hole section is formed with a guiding arc surface.
[0018] Preferably, the countertop cover is made of nylon.
[0019] The second objective of this utility model is to provide a template machine, including the above-mentioned template machine's rotary shuttle upper plate position noise reduction structure.
[0020] The beneficial effects of this utility model are:
[0021] This invention employs a sound insulation method, in which an annular sealing gasket is fixedly fitted around the needle plate and clamped and fixed horizontally between the needle plate and the table cover plate. This prevents noise generated by the rotary hook from leaking through the gap between the needle plate and the table cover plate to the top of the table cover plate, thereby reducing the noise above the table cover plate and improving the working environment.

[0035] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. These embodiments are only used to illustrate this utility model and are not intended to limit it.
[0036] In the description of this utility model, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0037] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0038] Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0039] Through long-term research, the inventors discovered that, for existing template sewing machines, although the needle plate is located in the mounting holes on the table cover, a gap exists at the connection point between the needle plate and the base below the table cover after the needle plate is fixedly connected. This allows noise generated by the rotary hook to easily leak above the table cover, resulting in excessive noise from the template sewing machine, causing noise disturbance and affecting the user's physical and mental health. Furthermore, the existing needle plate is made of 304 stainless steel with a thickness of 4mm. Because it is directly mounted on the base, vibrations from the base and the rotary hook are easily transmitted to the needle plate, causing significant needle plate vibration and affecting the sewing effect.
[0040] Examples, such as Figures 1-6 As shown, a noise reduction structure for the needle plate position on the rotary hook of a template machine includes: a base 10, a rotary hook 20, a table cover plate 30, a needle plate 40, and an annular sealing gasket 50; the base 10 has a rotary hook shaft 60 inside; the rotary hook 20 is disposed in a rotary hook cavity 11 at one end of the base 10, and the rotary hook 20 is connected to one end of the rotary hook shaft 60; the table cover plate 30 is disposed above the base 10, and a mounting hole 31 is formed on the table cover plate 30, which is located directly above the rotary hook 20; the needle plate 40 is disposed in the mounting hole 31; the annular sealing gasket 50 is sleeved on the periphery of the needle plate 40, and the annular sealing gasket 50 is clamped between the needle plate 40 and the table cover plate 30.
[0041] This invention employs a sound insulation method, in which an annular sealing gasket 50 is fixedly sleeved around the needle plate 40, and the annular sealing gasket 50 is clamped and fixed horizontally between the needle plate 40 and the table cover plate 30. This can prevent the noise generated by the rotary hook 20 from leaking to the top of the table cover plate 30 through the gap between the needle plate 40 and the table cover plate 30, thereby reducing the noise above the table cover plate 30 and improving the working environment.
[0042] Specific embodiment 1, such as Figures 1-6As shown, a noise reduction structure for the needle plate position on the rotary hook of a template machine includes: a base 10, a rotary hook 20, a table cover plate 30, a needle plate 40, and an annular sealing gasket 50; the base 10 is arranged horizontally, and a rotary hook shaft 60 is installed inside the base 10; the rotary hook 20 is disposed in a rotary hook cavity 11 at one end of the base 10, and the rotary hook 20 is connected to one end of the rotary hook shaft 60; the table cover plate 30 is installed above one end of the base 10, and a mounting hole 31 is formed on the table cover plate 30, which is located directly above the rotary hook 20; the needle plate 40 is disposed in the mounting hole 31; the annular sealing gasket 50 is sleeved on the periphery of the needle plate 40, and the annular sealing gasket 50 is clamped between the needle plate 40 and the table cover plate 30.
[0043] Specifically, such as Figures 2-6 As shown, the sealing connection between the annular sealing gasket 50 and the needle plate 40 and the table cover plate 30 is achieved as follows: The annular sealing gasket 50 includes an integrally formed horizontal sealing part 51 and a vertical buffer part 52. The horizontal sealing part 51 is located above the vertical buffer part 52, and the vertical buffer part 52 is fixedly connected to the bottom end of the horizontal sealing part 51. The inner diameter of the vertical buffer part 52 is smaller than the inner diameter of the horizontal sealing part 51, so as to form a stepped inner cavity that is larger at the top and smaller at the bottom inside the annular sealing gasket 50. A lower positioning surface 53 is formed in the inner cavity of the annular sealing gasket 50, and the lower positioning surface 53 is the upper surface of the vertical buffer part 52.
[0044] The needle plate 40 includes an integrally formed upper plate 41 and a lower plate 42. The lower plate 42 is located directly below the upper plate 41, and the radial dimension of the upper plate 41 is larger than the radial dimension of the lower plate 42, so as to form an upper positioning surface 43 on the periphery of the needle plate 40. The upper positioning surface 43 is the lower surface of the upper plate 41 and surrounds the lower plate 42.
[0045] The inner diameter of the vertical buffer part 52 is smaller than the outer diameter of the upper plate 41, and the inner diameter of the vertical buffer part 52 is larger than the outer diameter of the lower plate 42. The inner diameter of the horizontal sealing part 51 is equal to or slightly smaller than the outer diameter of the upper plate 41, so that after the annular sealing gasket 50 is fitted around the needle plate 40, the horizontal sealing part 51 of the annular sealing gasket 50 is fixed to the circumference of the upper plate 41 of the needle plate 40. The lower positioning surface 53 of the annular sealing gasket 50 coincides with the upper positioning surface 43 of the needle plate 40, that is, the upper surface of the vertical buffer part 52 coincides with the lower surface of the upper plate 41.
[0046] The mounting hole 31 includes an upper section 32 and a lower section 33 that are vertically connected. The radial dimension of the upper section 32 is larger than that of the lower section 33, and the radial dimension of the lower section 33 is larger than the outer diameter of the lower plate 42, so that the mounting hole 31 is stepped, with the upper part larger than the lower part. A stop surface 34 that matches the vertical buffer part 52 is formed in the inner cavity of the mounting hole 31. The radial dimension of the upper section 32 is smaller than the outer diameter of the horizontal sealing part 51, so that after the annular sealing gasket 50 and the needle plate 40 are installed in the mounting hole 31 on the table cover plate 30, the needle plate 40... Under the pressure of the table cover plate 30, the horizontal sealing part 51 of the annular sealing gasket 50 is clamped and fixed between the needle plate 40 and the table cover plate 30, so that the needle plate 40 and the table cover plate 30 are fixedly connected in the horizontal direction; at the same time, the vertical buffer part 52 of the annular sealing gasket 50 is clamped and fixed between the upper plate 41 and the table cover plate 30, so as to achieve a sealed connection between the needle plate 40 and the table cover plate 30 in the vertical direction, and reduce the vibration transmitted from the table cover plate 30 to the needle plate 40, reduce the impact of the needle plate 40 vibration on sewing, and thus improve the sewing effect.
[0047] Preferably, the annular sealing gasket 50 is made of nitrile rubber, which can improve the horizontal sealing effect and vertical vibration reduction effect between the needle plate 40 and the table cover plate 30.
[0048] More preferably, a guide arc surface 35 is formed at the top of the mounting hole 31, that is, a guide arc surface 35 is formed at the top of the upper hole section 32, and the radial dimension of the guide arc surface 35 gradually decreases from top to bottom, so as to facilitate the installation of the needle plate 40 with the annular sealing gasket 50 in the mounting hole 31 of the table cover plate 30.
[0049] Preferably, the countertop cover 30 is made of nylon, which can further reduce the transmission of noise generated by the rotary hook 20 to the top of the countertop cover 30.
[0050] An embodiment of a template machine includes the above-described template machine's rotary shuttle upper plate position noise reduction structure.
[0051] The working principle of the noise reduction structure at the upper guide plate position of the template machine in this utility model is as follows:
[0052] This invention features an annular sealing gasket made of nitrile rubber installed in the gap between the needle plate and the table cover. The annular sealing gasket is placed on the step of the needle plate, and the outer ring of the annular sealing gasket is larger than the shape of the needle plate, which can just fill the gap between the needle plate and the table cover. This prevents noise from the shuttle from leaking through the gap to the top of the table cover. When the needle plate is installed, it is pressed on the annular sealing gasket, so that the lower surface of the needle plate does not directly contact the table cover, thus isolating the needle plate from direct contact with the table cover and effectively reducing vibration at the needle plate.
[0053] Compared with the prior art, the present invention has at least the following beneficial technical effects:
[0054] 1. Compared with the existing structure of template machines, it has a significant effect on suppressing the noise of the whole machine, reducing the vibration at the needle plate, reducing the impact of needle plate vibration on sewing, and effectively improving the sewing effect.
[0055] 2. Compared with the existing structure of template machines, it can significantly reduce the noise transmitted to the user at the rotary hook, effectively reducing the noise disturbance to the user.
[0056] 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.
