Description

Technical Field

[0001] This utility model relates to the field of die-cutting technology, specifically to a safety protection device for a hand-operated die-cutting machine. Background Technology

[0002] A manual die-cutting machine, also known as a hand-operated die-cutting machine, involves manually placing the cardboard to be die-cut inside the machine. Because operators frequently put their hands inside the machine during operation, and the machine operates under high pressure, there is a significant safety risk.

[0003] To solve the above problems, existing technologies usually install a guardrail on the top of the die-cutting machine. By installing the guardrail, a small gap is created between the rotating pressure plate and the guardrail during rotation, thereby preventing the operator's hands from reaching into the die-cutting machine.

[0004] However, the safety devices of the aforementioned manual die-cutting machines are not sufficiently safe, and there is a risk of fingers being pinched during the rotation of the rotating pressure plate, so safety accidents still occur in the packaging industry. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention aims to provide a safety protection device for hand-operated ...

[0006] This utility model is achieved through the following technical solution: A safety protection device for a handheld beer dispenser includes a protective railing installed on the top of the handheld beer dispenser, and further includes: The guardrail has rods at both ends, and the lower ends of the two rods are rotatably connected to the left and right sides of the hand-held machine, respectively, so that the guardrail can rotate to the front or rear of the hand-held machine; the limiting component is used to limit the rotation range of the guardrail; the guardrail can rotate to the protective position in front of the hand-held machine under its own gravity. A contact switch is triggered when the guardrail rotates toward the rear of the hand-operated machine. The contact switch is used to control the hand-operated machine to start and stop.

[0007] Compared to existing technologies, which pose a risk of hand pinching during the rotation of the rotating pressure plate and still result in safety accidents in the packaging industry, this utility model provides a safety protection device for a hand-operated punching machine. This design features a protective railing with a rearward rotation buffer distance during the rotation of the pressure plate to prevent hand pinching. Simultaneously, when the protective railing rotates rearward, a contact switch can be used to stop the hand-operated punching machine, thereby improving its operational safety. Specifically, the protective railing is located above the rotating pressure plate on the side, with a small gap between the railing and the rotating pressure plate's rotation range. When the rotating pressure plate rotates inward to below the protective railing, the small gap prevents an arm from passing through. If the arm is still inside the punching machine adjusting the template at this time, the arm will be pinched, preventing the rotating pressure plate from closing and thus providing a safety warning to the operator to remove their arm. Secondly, limiters and contact switches are installed on at least one side of the hand-held punching machine. The rods at both ends of the guardrail are rotatably connected to the sides of the hand-held punching machine, and the rotation range is limited by the limiters. If the guardrail can automatically rotate towards the front of the hand-held punching machine under its own weight, when it is blocked by the limiters, the guardrail is in the protective position, and the rods press the contact switches, allowing the hand-held punching machine to continue running. When the arm is clamped in the gap, it will push the guardrail to rotate a certain distance to the rear. At this time, the rods disengage from the contact switches, the contact switches are released, and the contact switches control the hand-held punching machine to stop, so as to avoid the hand-held punching machine from continuing to run and injuring the arm, thus improving the operational safety performance of the hand-held punching machine.

[0008] A further optimization involves a specific structure for a limiting component, comprising two limiting rods positioned on the side of the hand-held machine. These two limiting rods are located at the front and rear positions of the component, respectively, to block the guardrail from rotating forward and backward. The two limiting rods effectively limit the rotational position of the guardrail by blocking the component.

[0009] Further optimization, as a specific method of rotatably connecting the rod and the hand-held machine, also includes a fixing block, with fixing blocks provided on both the left and right sides of the hand-held machine; the fixing block has a rotating shaft, the rotating shaft is rotatably connected to the fixing block, and the rotating shaft can rotate around its own axis; The lower parts at both ends of the guardrail are respectively fixedly connected to the two rotating shafts.

[0010] To achieve further optimization and enable free rotation, a mounting hole is provided in the center of the fixed block, and a bearing is coaxially mounted inside the mounting hole. The rotating shaft is connected to the inner side of the bearing.

[0011] In a further optimization, as a detachable connection method, the side wall of the rotating shaft has a through hole, through which the lower end of the rod passes and is fixed by bolts. The bolts can pass through the side wall of the rotating shaft and be screwed onto the rod.

[0012] To further optimize the system and ensure stable safety of the guardrail, the limiting component is located on the outer surface of the fixing block, and both fixing blocks are equipped with limiting components; the contact switch is located on the top of the fixing block, and both fixing blocks are equipped with contact switches.

[0013] Further optimizations, to improve operational convenience, ensure that the center of gravity of the guardrail remains in front of the rotation center of the lever within its rotation range. When the guardrail rotates to the protective position in front of the handheld machine under its own weight, the contact switch is pressed down by the lever. When the guardrail rotates backward, the lever disengages from the contact switch. Specifically, by shifting the center of gravity forward and optimizing the position of the limiting lever, when the guardrail rotates backward and is blocked by the rear limiting lever, it can still rotate forward under its own weight; that is, after the arm is withdrawn, the guardrail automatically returns to its original position.

[0014] For further optimization, in order to actively adjust the center of gravity, the guardrail has an extension section that extends towards the front of the hand-held machine, and the extension section has a counterweight.

[0015] To further optimize the design and prevent hard contact between the arm and the guardrail, a flexible sleeve is fitted onto the pole section within the extension segment.

[0016] Further optimization involves facilitating the guidance of the rod and enabling it to trigger the contact switch. The switch end face of the contact switch is an inclined surface, which is inclined inward from the front to the rear.

[0017] Compared with the prior art, this utility model has the following advantages and beneficial effects: This utility model provides a safety protection device for a hand-operated beer machine. With this solution, during the rotation of the rotating pressure plate, the protective railing has a buffer distance for rotating backward to avoid pinching the hand; at the same time, when the protective railing rotates backward, the hand-operated beer machine can be stopped by a contact switch, thereby improving the operational safety performance of the hand-operated beer machine.

[0023] Example: This embodiment provides a safety protection device for a mobile phone, such as... Figures 1-5 As shown, it includes a protective railing 1 installed on the top of the handheld beer dispenser, and also includes: The limiting component 2 has rods 101 at both ends of the guardrail 1. The lower ends of the two rods 101 are rotatably connected to the left and right sides of the hand-held machine, respectively, so that the guardrail 1 can rotate to the front or rear of the hand-held machine. The limiting component 2 is used to limit the rotation range of the guardrail 1. The guardrail 1 can rotate to the protective position in front of the hand-held machine under its own gravity. Contact switch 3: During the rotation of the guardrail 1 toward the rear of the hand-held machine, the rod 101 can trigger contact switch 3, which is used to control the hand-held machine to start and stop.

[0024] Compared to existing technologies, which pose a risk of hand pinching during the rotation of the rotating pressure plate and still result in safety accidents in the packaging industry, this utility model provides a safety protection device for a hand-operated punching machine. In this design, the protective railing 1 has a buffer distance for rearward rotation during the rotation of the pressure plate to prevent hand pinching. Simultaneously, when the protective railing 1 rotates rearward, the hand-operated punching machine can be stopped via a contact switch 3, thereby improving the operational safety performance of the hand-operated punching machine. Specifically, the protective railing 1 is located above the rotating pressure plate on the side, with a small gap between the protective railing 1 and the rotation range of the rotating pressure plate. Thus, when the rotating pressure plate rotates inward to below the protective railing 1, the small gap prevents an arm from passing through. If the arm is still inside the hand-operated punching machine adjusting the template at this time, the arm will be pinched, preventing the rotating pressure plate from closing, thus achieving the protective function and reminding the operator to remove their arm. Secondly, limiters 2 and contact switches 3 are provided on at least one side of the hand-held beer machine. The rods 101 at both ends of the guardrail 1 are rotatably connected to the two sides of the hand-held beer machine, and the rotation range is limited by the limiters 2. If the guardrail 1 can automatically rotate to the front of the hand-held beer machine under its own weight, when it is blocked by the limiters 2, the guardrail 1 is just in the protective position, and the rods 101 press the contact switches 3, so that the hand-held beer machine continues to run. When the arm is clamped in the gap, it will push the guardrail 1 to rotate a certain distance to the rear. At this time, the rods 101 disengage from the contact switches 3, the contact switches 3 are released, and the contact switches 3 control the hand-held beer machine to stop, so as to avoid the hand-held beer machine from continuing to run and injuring the arm, thus improving the operational safety performance of the hand-held beer machine.

[0025] In some embodiments, as a specific structure of a limiting member 2, the limiting member 2 includes two limiting rods disposed on the side of the hand-held machine. The two limiting rods are respectively located at the front and rear positions of the rod 101 to block the guardrail 1 during its forward and rearward rotation. The two limiting rods can block the rod 101 to limit the rotational position of the guardrail 1.

[0026] In some embodiments, as a specific way of rotatably connecting the rod 101 and the hand-held machine, a fixing block 4 is also included, and fixing blocks 4 are provided on both the left and right sides of the hand-held machine; the fixing block 4 is equipped with a rotating shaft 5, the rotating shaft 5 is rotatably connected to the fixing block 4, and the rotating shaft 5 can rotate around its own axis; The lower parts of both ends of the guardrail 1 are fixedly connected to the two rotating shafts 5 respectively.

[0027] In some embodiments, to enable free rotation, the fixing block 4 has a mounting hole in the middle, and a bearing 6 is coaxially mounted in the mounting hole, with the rotating shaft 5 and the inner side of the bearing 6 connected.

[0028] In some embodiments, as a detachable connection method, the side wall of the rotating shaft 5 has a through hole, and the lower end of the rod 101 is used to pass through the through hole and be fixed by bolts. The bolts can pass through the side wall of the rotating shaft 5 and the rod 101 for screwing.

[0029] In some embodiments, in order to achieve stable safety protection of the guardrail 1, the limiting member 2 is provided on the outer surface of the fixing block 4, and the two fixing blocks 4 are provided with the limiting member 2; the contact switch 3 is provided on the top of the fixing block 4, and the two fixing blocks 4 are provided with the contact switch 3.

[0030] In some embodiments, to improve ease of operation, within the rotation range of the guardrail 1, the center of gravity of the guardrail 1 is always located in front of the rotation center of the rod 101; when the guardrail 1 rotates to the protective position in front of the handheld machine under its own weight, the contact switch 3 is pressed by the rod 101; when the guardrail 1 rotates to the rear, the rod 101 disengages from the contact switch 3. Specifically, by shifting the center of gravity forward and optimizing the position of the limiting rod, when the guardrail 1 rotates to the rear and is blocked by the rear limiting rod, the guardrail 1 can also rotate to the front under its own weight; that is, after the arm is withdrawn, the guardrail 1 can automatically return to its original position.

[0031] In some embodiments, for active adjustment of the center of gravity, the guardrail 1 has an extension section extending towards the front of the hand-held machine, and the extension section has a counterweight 7.

[0032] In some embodiments, to avoid hard contact between the arm and the guardrail 1, a flexible sleeve 8 is fitted on the pole segment within the extension section.

[0033] In some embodiments, to facilitate guiding the rod 101 and to facilitate the rod 101 triggering the contact switch 3, the switch end face of the contact switch 3 is an inclined surface, and the inclined surface is inclined inward from the front side to the rear side.

[0034] The specific working principle of this solution is as follows: The guardrail 1 is located above the rotating pressure plate on the side. There is a small gap between the guardrail 1 and the rotating pressure plate. When the rotating pressure plate rotates inward to below the guardrail 1, the gap is too small to allow the arm to pass through. If the arm is still adjusting the template inside the hand-operated machine at this time, the arm will be clamped and the rotating pressure plate will not be able to close, thus achieving the protective function and reminding the operator to take out the arm. Secondly, limiters 2 and contact switches 3 are installed on both the left and right sides of the hand-held beer machine. The rods 101 at both ends of the guardrail 1 are rotatably connected to the sides of the hand-held beer machine, and the rotation range is limited by the limiters 2. If the guardrail 1 can automatically rotate towards the front of the hand-held beer machine under its own weight, when it is blocked by the limiter rod in the limiter 2 located on the front side, the guardrail 1 is in the protective position, and the rod 101 presses the contact switch 3, allowing the hand-held beer machine to continue running. When the arm is clamped in the gap, it will push the guardrail 1 to rotate a certain distance to the rear. At this time, the rod 101 disengages from the contact switch 3, the contact switch 3 is released, and the contact switch 3 controls the hand-held beer machine to stop, so as to avoid the hand-held beer machine continuing to run and injuring the arm, thus improving the operational safety performance of the hand-held beer machine. When the arm is pulled out, the guardrail 1 will return to its original position under its own weight and press the contact switch 3 again to automatically turn on the hand-held beer machine.

[0035] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
