[0002] A button punching machine is a tool used to install buttons. It can quickly and easily fix buttons on clothing or other materials. The button punching machine connects buttons and corresponding fixings together by using molds and pressure, thereby achieving the installation of buttons. It is widely used in clothing, luggage and other industries that require button fixing.

[0003] When the button punching machine is in use, a person usually holds the object to be buttoned and moves it at the lower end of the button punching machine to change the button punching position. However, the button punching end of the current button punching machine is usually directly exposed to the outside and lacks protection. When the button punching end performs a downward punching movement, it is easy to accidentally injure the operator's hand. Based on the above situation, it is necessary to design a protective device for the button punching machine to solve the above problem. Utility Model Content

[0004] The utility model provides a protective device for a button punching machine, so as to solve the problem in the prior art that when the button punching end performs a downward punching movement, the operator's hand is easily injured by mistake.

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0019] Reference Figure 1-Figure 3As shown, a protective device for a button punching machine includes a base 1, an opening and closing assembly and a protective assembly. A button punching machine body 11 is provided on the base 1. A button punching member 13 is connected to the button punching machine body 11 through a driving device 12. A raised button pressing member 14 is arranged opposite to the button punching member 13 on the base 1. The driving device 12 can be a hydraulic telescopic rod or other mechanical transmission mechanism capable of up and down reciprocating motion. The button punching member 13 is driven to be pressed on the raised button pressing member 14 by the downward movement of the driving device 12 to perform a button punching operation. This technology is a prior art, and those skilled in the art should know it and will not be described in detail here. The opening and closing assembly is used to open and close the button punching machine body 11. The opening and closing assembly includes two pressure plates 2 and a switch 21 arranged at the bottom of the two pressure plates 2, and the switch 21 is electrically connected to the button punching machine body 11. It should be noted that the electrical connection described in this scheme refers to connection through a guide, etc., which is a technology known to those skilled in the art. The upper end of the base 1 Two reserved grooves 22 are provided on the surface, and the pressure plate 2 is slidably connected to the inside of the reserved groove 22 up and down. When performing the button punching operation, the person holds the cloth or other items that need to be buttoned, and places his hands on the pressure plate 2 on both sides of the raised button punching member 13 respectively, and places the items that need to be buttoned on the raised button pressing member 14. At this time, the person's hands are located on both sides of the raised button pressing member 14, which are misaligned with the button punching member 13. Even if the button punching member 13 drops, it will not accidentally injure the operator's hands. The two pressure plates 2 will drive the two switches 21 to move downward and be turned on by pressure, forming a circuit to energize the button punching machine body 11 as a whole. At this time, if the driving device 12 is turned on alone, the button punching operation can be performed. If the button punching machine body 11 is not energized, the button punching operation cannot be performed even if the switch 21 of the driving device 12 is pressed. The switch 21 of the driving device 12 can be set at the bottom, and the driving device 12 is started by stepping on the switch 21 with the foot. This technology is a prior art and is not shown in the figure.

[0020] Furthermore, the protective component is disposed on the button-making member 13 for protecting the outer side of the button-making member 13 , and the protective component includes a connecting plate 3 connected to the button-making member 13 and protective plates 31 hinged to both sides of the connecting plate 3 .

[0021] Among them, when the button-punching member 13 moves downward to perform the button-punching operation, the protective plate 31 contacts the raised button-pressing member 14, so that the two protective plates 31 swing in opposite directions at the hinges between the protective plates 31 and the connecting plate 3, forming interception protection on both sides of the button-punching member 13 to prevent people from accidentally moving their hands under the button-punching member 13 when moving the objects to be punched on the raised button-pressing member 14, causing accidental injuries. Even if the pressure plate 2 is subjected to other forces besides the pressure of the operator's hands to turn on the switch 21 and energize the button-punching machine body 11 as a whole, the interception of the protective plates 31 on both sides further prevents people's hands from moving under the button-punching member 13, thereby improving safety.

[0022] Furthermore, a side of the bottom of the protection plate 31 close to the button-punching member 13 is connected to a limiting plate 32 . When one side of the two protection plates 31 respectively contacts the two limiting plates 32 , an “eight” shape is formed between the two protection plates 31 .

[0023] Among them, when the button-punching member 13 drives the protective plate 31 to move upward and break away from the interference with the raised button-pressing member 14, the button-punching member 13 will reset and swing under the action of its own gravity, and interfere with the limit plate 32. At this time, the two limit plates 32 form an "eight" shape, which makes it easier for the raised button-pressing member 14 to expand to both sides when the protective plate 31 interferes downward again.

[0024] Furthermore, a movable shaft 33 is rotatably connected to the bottom end of the protection plate 31 .

[0025] When the button pressing member moves downward to perform the button pressing operation, the movable shaft 33 first contacts the object to be buttoned on the raised button pressing member 14, and rolls it through the movable shaft 33, thereby converting the sliding friction of the protective plate 31 into rolling friction, reducing the friction damage of the protective plate 31 to the object to be buttoned.

[0026] Furthermore, rounded corners 4 are provided on both sides of the upper end of the raised button member 14 , and the arc surface of the rounded corners 4 is in contact with the movable shaft 33 .

[0027] The rounded corners 4 can reduce the friction between the object to be buttoned and the edge of the raised button pressing member 14, thereby improving the production quality of the object to be buttoned.

[0028] Furthermore, the reserved groove 22 is connected to the pressure plate 2 via an elastic member 5 .

[0029] Among them, the elastic member 5 can be a structure with a certain elastic force such as a spring or a reed. When the pressure plate 2 loses the downward force from the outside, the pressure plate 2 is pushed upward under the elastic force of the elastic member 5, so that the switch 21 will not be turned on under pressure. At this time, the button punching machine body 11 will be powered off as a whole.

[0030] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
