Description

Technical Field

[0001] The utility model relates to the technical field of acupuncture machines, in particular to an acupuncture machine which is convenient for cleaning and replacing needles. Background Art

[0002] When the needle reaches a certain depth, it starts to rise. Due to the forward direction of the barbed hook, the displaced fibers break away from the barbed hook and remain in the fiber web in an almost vertical state, just like many fiber bundles "pins" nailed into the fiber web, so that the compression of the fiber web cannot be restored. If the fiber web is punctured dozens or hundreds of times per square centimeter, a considerable number of fiber bundles will be pierced into the fiber web, and the friction between the fibers in the fiber web will increase, the strength of the fiber web will increase, and the density will increase. The fiber web will form a non-woven product with certain strength, density, elasticity and other properties.

[0003] After searching, the existing Chinese patent announcement number is: CN 220520780 U, which provides a needle loom. This patent arranges a collecting device under the support mesh plate to collect the fibers dropped on the support mesh plate, effectively preventing the fibers from falling into the machine and affecting the normal operation of the machine under long-term accumulation. The operating door is opened and the collecting device is pulled out and retracted through the connecting assembly. The structure is simple and the operation is convenient.

[0004] Although the above patent can collect the fibers dropped from the support plate and effectively prevent the fibers from falling into the machine, the above needle loom still has the following problem: when in use, since the needles are installed on the needle plate, it is not convenient to replace the needles when they break.

[0005] In view of the above problems, a needle loom which is convenient for cleaning and replacing needles is proposed. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0028] See also Figure 1-6 The utility model provides a technical solution: an acupuncture machine which is convenient for cleaning and replacing needles, comprising a frame 1, a top of the frame 1 is fixedly installed with an up-and-down reciprocating drive mechanism 2, the output end of the up-and-down reciprocating drive mechanism 2 slides through the frame 1 and extends to the inside of the frame 1, a needle plate 3 is fixedly installed at the output end of the up-and-down reciprocating drive mechanism 2, and a needle 7 is arranged at the bottom of the needle plate 3, two limiting guide rods 4 are fixedly installed inside the frame 1, and limiting baffles 6 are fixedly installed at the lower ends of the two limiting guide rods 4, and a fixing plate 10 is slidably connected to the surface of the two limiting guide rods 4, and a cleaning hole 11 is opened on the fixing plate 10, and the cleaning hole 11 coincides with the needle 7, and tension springs 5 ​​are movably sleeved on the two limiting guide rods 4, and the upper ends of the two tension springs 5 ​​are fixedly connected to the inside of the frame 1, and the lower ends of the two tension springs 5 ​​are fixedly connected to the fixing plate 10, and a rubber ring is arranged inside the cleaning hole 11.

[0029] Start the up and down reciprocating drive mechanism 2 (the up and down reciprocating drive mechanism 2 can be a push rod motor or a mechanism that can reciprocate up and down), so that the up and down reciprocating drive mechanism 2 drives the needle plate 3 to move downward, and drives the needle 7 to move downward at the same time, so that the needle 7 enters the interior of the cleaning hole 11, and as the needle plate 3 continues to move downward, the needle plate 3 squeezes the fixed plate 10, and then the fixed plate 10 moves on the two limiting guide rods 4, and then the two tension springs 5 ​​are stretched. When the needle plate 3 moves upward, the needle plate 3 no longer squeezes the fixed plate 10, and then the fixed plate 10 is reset by the tension of the tension spring 5, and then the impurities on the needle 7 are scraped off through the fixed plate 10 and the cleaning hole 11, so as to facilitate the scraping of impurities on the surface of the needle 7, thereby improving the cleaning effect of the needle 7 and reducing the accumulation of impurities on the needle 7.

[0030] A fixing groove 13 is provided at the bottom of the needle plate 3, and a fixing block 12 is slidably connected inside the fixing groove 13. The bottom of the fixing block 12 is fixedly connected to the upper end of the needle 7. An insertion rod 15 is slidably connected inside the needle plate 3. A plug hole 14 is provided on the surface of the fixing block 12. The plug rod 15 slides and engages inside the plug hole 14. An elastic spring 18 is fixedly installed inside the needle plate 3, and one end of the elastic spring 18 close to the plug rod 15 is fixedly connected to the plug rod 15. A moving plate 16 is slidably connected inside the needle plate 3, and a groove 17 is provided on the surface of the moving plate 16. A sliding rod 8 is fixedly installed on one side of the moving plate 16. A connecting plate 9 is fixedly installed on one end of the sliding rod 8 that slides through the needle plate 3. A bolt 21 is rotatably connected inside the connecting plate 9, and the bolt 21 is threadedly connected to the inside of the needle plate 3.

[0031] The bolt 21 is turned to make the bolt 21 drive the connecting plate 9 to move, thereby pulling the sliding rod 8 to slide inside the needle plate 3, thereby moving the movable plate 16, thereby making the insertion rod 15 coincide with the groove 17, so that the insertion rod 15 is reset by the pulling force of the elastic spring 18, thereby making the insertion rod 15 no longer located inside the insertion hole 14, thereby releasing the fixation of the fixing block 12. When it is necessary to fix the fixing block 12 and the needle 7, the fixing block 12 is inserted into the fixing groove 13, and then the bolt 21 is turned in the opposite direction to make the connecting plate 9 move in the opposite direction, thereby making one end of the insertion rod 15 slide along the inclined surface of the groove 17, thereby making the insertion rod 15 gradually slide into the inside of the insertion hole 14, stretching the elastic spring 18, thereby facilitating the fixation of the fixing block 12 and the needle 7, facilitating the installation and removal of the needle 7, improving the convenience of installing and removing the needle 7, and reducing the difficulty of disassembly.

[0032] A first magnet 19 is fixedly installed inside the fixing groove 13, and a second magnet 20 is fixedly installed on the top of the fixing block 12. The second magnet 20 and the first magnet 19 attract each other.

[0033] The first magnet 19 and the second magnet 20 are provided to prevent the fixing block 12 from sliding out of the fixing groove 13 after the fixing of the fixing block 12 is released, thereby preventing the maintenance personnel from being pierced.

[0034] Working principle:

[0035] Start the up and down reciprocating drive mechanism 2, so that the up and down reciprocating drive mechanism 2 drives the needle plate 3 to move downward, and drives the needle 7 to move downward at the same time, so that the needle 7 enters the inside of the cleaning hole 11, and as the needle plate 3 continues to move downward, the needle plate 3 squeezes the fixed plate 10, and then the fixed plate 10 moves on the two limiting guide rods 4, and then the two tension springs 5 ​​are stretched. When the needle plate 3 moves upward, the needle plate 3 no longer squeezes the fixed plate 10, and then the fixed plate 10 is reset by the tension of the tension spring 5, and then the impurities on the needle 7 are scraped off through the fixed plate 10 and the cleaning hole 11.

[0036] By rotating the bolt 21, the bolt 21 drives the connecting plate 9 to move, thereby pulling the sliding rod 8 to slide inside the needle plate 3, thereby moving the movable plate 16, thereby causing the insertion rod 15 to coincide with the groove 17, so that the insertion rod 15 is reset by the pulling force of the elastic spring 18, thereby causing the insertion rod 15 to no longer be located inside the insertion hole 14, thereby releasing the fixation of the fixing block 12. When it is necessary to fix the fixing block 12 and the needle 7, the fixing block 12 is inserted into the fixing groove 13, and then the bolt 21 is rotated in the opposite direction to cause the connecting plate 9 to move in the opposite direction, thereby causing one end of the insertion rod 15 to slide along the inclined surface of the groove 17, thereby causing the insertion rod 15 to gradually slide into the inside of the insertion hole 14, stretching the elastic spring 18, thereby facilitating the fixation of the fixing block 12 and the needle 7.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
