Description

Technical Field

[0001] The utility model relates to the field of embroidery machines, in particular to a needle bar frame. Background Art

[0002] Embroidery machine, I think everyone should understand from the literal meaning, embroidery machine, embroidery machine, or embroidery machinery.

[0003] In the actual use of the embroidery machine, the needle bar moves up and down to drive the needle head to rise and fall, and embroidery is realized. In the process of lifting and lowering the needle bar in the embroidery machine, the needle bar frame needs to be used to limit the lifting and lowering trajectory of the needle bar, so as to ensure the stability of the needle bar lifting and lowering. In the actual use of the existing needle bar frame, the needle bar frame is a simple fixed frame, and the corresponding limiting holes are opened on the fixed frame. The limiting holes are used to limit the needle bar. However, in actual use, the needle bar is lifted and lowered in the limiting holes for a long time, which is prone to wear and tear. It does not have the function of lubrication, which affects the service life of the needle bar. The needle bar is easily shaken due to wear, so the shaking of the needle bar easily affects the accuracy of embroidery. For this reason, a new technical solution needs to be designed to solve it. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet actual needs, and provide a needle bar rack to solve the technical problem that the current needle bar is lifted and lowered in the limit hole for a long time, which is prone to wear and tear, has no lubrication function, and affects the service life of the needle bar.

[0009] Preferably, the limit plate is a hollow structure, and a lubricating oil box is fixed to the outer wall of one of the vertical plates. The bottom of the lubricating oil box is connected to the limit plate through a conduit, and the outer wall of the conduit is fixedly connected to a solenoid valve. During actual use, the solenoid valve is opened periodically so that the lubricating oil can be introduced into the limit plate by utilizing its own weight. The lubricating oil can lubricate the ball bearing, thereby further reducing wear and further improving the effect of protecting the needle rod.

[0010] Preferably, a buffer plate is provided on the top of the limiting plate, and a plurality of evenly distributed springs are fixed on the bottom of the buffer plate, the tail end of the spring is fixedly connected to the corresponding position of the top of the limiting plate, and a through hole is opened on the surface of the buffer plate corresponding to the limiting hole. In actual use, the needle bar passes through the limiting hole, and in the process of the needle bar rising and falling, the fixing ring of the outer wall of the needle bar hits the buffer plate to compress the spring to buffer the impact force, thereby avoiding direct impact on the limiting plate, which may cause the limiting plate to be damaged due to long-term impact, thereby achieving the effect of buffering protection.

[0011] Preferably, a matching rubber pad is fixedly glued to the top of the buffer plate, and the provision of the rubber pad can further enhance the buffering effect.

[0012] Preferably, a glass observation window is embedded in the outer wall of the lubricating oil box. The provision of the glass observation window can facilitate viewing of the remaining amount of lubricating oil, thereby facilitating timely replenishment of the lubricating oil.

[0013] Preferably, a mounting plate is fixed on the upper side of one side wall of the vertical plate, and a mounting hole is provided on the outer wall of the mounting plate. The arrangement of the mounting plate and the mounting hole facilitates the installation and fixation of the entire device.

[0014] Preferably, the limiting holes on the upper and lower surfaces of the limiting plates are arranged correspondingly, thereby ensuring that the needle bar is accurately limited when being limited, and ensuring the accuracy of guiding the needle bar.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model embeds a plurality of evenly distributed balls in the inner cavity of the limiting hole, and utilizes the plurality of balls to limit the needle bar, and the balls can roll during the lifting and lowering process of the needle bar, thereby reducing wear and tear, playing a good role in protecting the needle bar and extending the service life of the needle bar. At the same time, the lubricating oil box can regularly introduce lubricating oil into the cavity of the limiting plate, thereby realizing lubrication of the balls, thereby further improving the lubrication protection of the needle bar during lifting and lowering, further avoiding wear and tear, and then avoiding the shaking of the needle bar, thereby ensuring the accuracy of embroidery.

[0017] 2. The utility model provides a buffer plate on the top of the limit plate, so that in the process of the needle bar rising and falling, the limit ring on the outer wall of the needle bar can hit the surface of the buffer plate, so that the spring can alleviate the impact force and avoid direct impact on the surface of the limit plate, thereby further improving the protection effect.

[0022] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0023] Embodiment 1: A needle bar frame, see Figures 1 to 3 , including: a vertical plate 1 and a limiting plate 3;

[0024] There are two vertical plates 1, and a horizontal plate 2 is fixed between the tops of the two vertical plates 1. The horizontal plate 2 can be used to stabilize the two vertical plates 1 to form a stable needle bar frame;

[0025] A limit plate 3 is fixedly installed between the middle and lower sides of the two vertical plates 1. A limit hole 31 is provided on the surface of the limit plate 3. A plurality of evenly distributed balls 32 are embedded in the inner cavity of the limit hole 31. In actual use, the needle bar passes through the upper and lower limit holes 31. In the process of the needle bar rising and falling, the balls 32 can roll, thereby avoiding the wear of the needle bar, thereby effectively protecting the needle bar and extending its service life.

[0026] Furthermore, the limit plate 3 is a hollow structure, and a lubricating oil box 5 is fixed to the outer wall of one of the vertical plates 1. The bottom of the lubricating oil box 5 is connected to the limit plate 3 through a conduit 51. The outer wall of the conduit 51 is fixedly connected to a solenoid valve 52. In actual use, the solenoid valve 52 is opened regularly, so that the lubricating oil can be introduced into the limit plate 3 by the weight of the lubricating oil. The lubricating oil can lubricate the ball 32, thereby further reducing wear and further improving the effect of protecting the needle rod.

[0027] Furthermore, a glass observation window 53 is embedded in the outer wall of the lubricating oil box 5. The setting of the glass observation window 53 can facilitate viewing of the remaining amount of lubricating oil, thereby facilitating timely replenishment of lubricating oil;

[0028] It is worth mentioning that a mounting plate 4 is fixed on the upper side of one side wall of the vertical plate 1, and a mounting hole 41 is provided on the outer wall of the mounting plate 4. The arrangement of the mounting plate 4 and the mounting hole 41 makes it convenient to install and fix the entire device;

[0029] It is worth noting that the limiting holes 31 on the surfaces of the upper and lower limiting plates 3 are arranged correspondingly, thereby ensuring that the needle bar is accurately limited when being limited, and ensuring the accuracy of guiding the needle bar.

[0030] like Figure 1 and 2 , 3; a buffer plate 33 is provided on the top of the limit plate 3, a plurality of evenly distributed springs 35 are fixed to the bottom of the buffer plate 33, the tail end of the spring 35 is fixedly connected to the corresponding position of the top of the limit plate 3, and a through hole is provided on the surface of the buffer plate 33 corresponding to the limit hole 31;

[0031] In actual use, the needle bar passes through the limiting hole 31. During the lifting and lowering process of the needle bar, the fixing ring on the outer wall of the needle bar impacts the buffer plate 33 to compress the spring 35 to buffer the impact force, thereby avoiding the situation in which the limiting plate 3 is easily damaged by long-term impact due to direct impact on the limiting plate 3, thus achieving a buffering protection effect.

[0032] Furthermore, a matching rubber pad 34 is fixedly glued to the top of the buffer plate 33 . The provision of the rubber pad 34 can further enhance the buffering effect.

[0033] The implementation principle of this embodiment is as follows: first, the device is installed and fixed using the mounting plate 4. During use, the needle bar passes through the upper and lower limit holes 31. During the lifting and lowering of the needle bar, the ball 32 can roll, thereby avoiding wear of the needle bar, thereby effectively protecting the needle bar and extending its service life. At the same time, the solenoid valve 52 is opened regularly, so that the lubricating oil can be introduced into the limit plate 3 by its own weight. The lubricating oil can lubricate the ball 32, thereby further reducing wear and further improving the effect of protecting the needle bar. At the same time, during the lifting and lowering of the needle bar, the fixing ring on the outer wall of the needle bar impacts the buffer plate 33 to compress the spring 35 to buffer the impact force, thereby avoiding direct impact on the limit plate 3, which may cause the limit plate 3 to be damaged by long-term impact, thereby achieving a buffering protection effect.
