Description

Technical Field

[0001] The utility model relates to an anti-clamping mechanism for a hot stamping die-cutting machine. Background Art

[0002] Some existing hot stamping die-cutting machines with anti-pinch function generally add an anti-pinch rod with a pressure sensor or a pressure switch on the inner side of the static template, and open an avoidance groove on the dynamic template;

[0003] However, when placing paper, it is usually inserted close to the moving template. When the moving template starts to clamp your hand, the anti-pinch rod will be touched first. However, the anti-pinch rod will pose a safety hazard after being used for a long time or multiple times. Or because of sensitivity problems, the anti-pinch rod will still press your fingers, and due to the existence of the avoidance groove, it is easy to get pinched with a slight pressure, but the consequences are not that serious.

[0004] Based on the above usage experience, we have designed a new anti-pinch mechanism for hot stamping die-cutting machines. Utility Model Content

[0005] According to the problems existing in the prior art, the utility model provides an anti-pinching mechanism for a hot stamping die-cutting machine, aiming to solve the problem of hidden dangers in the anti-pinching structure of the existing hot stamping die-cutting machine.

[0006] To achieve the above-mentioned purpose, the technical solution of the utility model is: a hot stamping die-cutting machine anti-pinch mechanism, including a static template and a dynamic template, an anti-pinch rod with a pressure switch is installed on the upper inner side of the static template; the dynamic template is provided with an avoidance groove cooperating with the anti-pinch rod; the upper part of the dynamic template is composed of a rotating plate and a frame, and the avoidance groove is located on the rotating plate; the rotating plate is rotatably installed between the left and right shaft ends of the frame through the axial holes on both sides of the lower part, and the rotating plate is in friction contact with the side of the frame; a pair of fixing rings are fixed on both sides of the rotating plate and the front of the frame, and a thick spring is inserted and installed between the fixing rings on the same side.

[0007] Preferably, the rotating plate and the top of the frame are both arc surfaces to prevent the hand wall from colliding with the edges and corners when being squeezed.

[0008] Preferably, the lower portion of the front surface of the rotating plate is processed with an arc surface.

[0009] Preferably, the shaft end surface is integrally connected with a fixing plate, which is inserted into the shaft hole of the rotating plate from the outside of the frame, and the fixing plate is fixed to the outer surface of the frame by screws.

[0010] The utility model has the following beneficial effects: it is safe to use, has a certain buffer space, avoids hand injuries to the greatest extent, and does not affect material discharge. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 2 It is a schematic diagram of the shaft end structure of the utility model. DETAILED DESCRIPTION

[0013] like Figure 1 , 2 As shown, a pinch prevention mechanism of a hot stamping die-cutting machine comprises a static template 1 and a dynamic template 2, wherein an anti-pinch rod 3 with a pressure switch is installed on the inner upper part of the static template 1; the dynamic template 2 is provided with an avoidance groove 4 cooperating with the anti-pinch rod 3; the upper part of the dynamic template 2 is composed of a rotating plate 5 and a frame 6, and the avoidance groove 4 is located on the rotating plate 5; the rotating plate 5 is rotatably installed between the left and right shaft ends 51 of the frame 6 through the axial holes on both sides of the lower part, and the rotating plate 5 is in frictional contact with the side of the frame 6; a pair of fixing rings 7 are fixed on both sides of the rotating plate 5 and the front of the frame, and a thick spring 8 is inserted and installed between the fixing rings 7 on the same side.

[0014] The lower part of the front of the rotating plate 5 is processed with an arc surface to avoid interference with the flipping. The surface of the shaft end 51 is integrally connected with a fixing plate 52, which is inserted into the shaft hole of the rotating plate 5 from the outside of the frame 6, and the fixing plate 52 is screwed to the outer surface of the frame to facilitate the rotation and installation connection of the rotating plate 5.

[0015] On the basis of the original anti-pinch rod 3, the utility model designs a groove that cooperates with the anti-pinch rod 3 on the rotating plate 5 of the movable template 2, and is rotatably installed between the left and right shaft ends 51 of the frame 6 through the shaft hole. The rotating plate 5 is in frictional contact with the side of the frame 6. Under normal circumstances, the movable template 2 can be kept as a whole without affecting the paper placement.

[0016] When the hand is pressed by the anti-pinch rod 3, the fingers or arms will be subjected to too much pressure, which will cause the rotating plate 5 to flip around the axis hole, causing the hand to be pushed away. Since a thick spring 8 is connected between the rotating plate 5 and the front of the frame, there is a certain pressure between the rotating plate 5 and the frame when the rotating plate 5 rotates, and there is a certain buffer space when the hand is squeezed, thereby avoiding hand injuries to the greatest extent and effectively avoiding the consequences caused by the sensitivity of the anti-pinch rod.

[0017] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent substitution or improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
