Technical Field

[0001] The utility model relates to the technical field of carton processing, in particular to a convex pattern pressing die for carton processing. Background Art

[0002] In carton processing, the embossing process is often used. Before the cardboard is folded into a carton, after being pressed by an embossing die, three-dimensional patterns or characters can be formed on the surface of the cardboard, which not only improves the grade and aesthetics of the later carton finished product, but also enhances the attractiveness of the product.

[0003] When the existing cardboard for making cartons is in the convex pattern embossing link, workers need to put their hands between the upper and lower dies to realize loading and unloading, and only after the upper group of cardboard is embossed can one-time unloading and loading be carried out, resulting in the problems of low efficiency and poor safety in the convex pattern pressing operation of the carton. Therefore, a convex pattern pressing die for carton processing is proposed to provide a pressing die that can automatically replace the lower die alternately after each embossing for the convex pattern embossing operation of carton processing. During the pressing of the upper group of cardboard, the next cardboard to be pressed can be placed on another set of dies in advance, so that personnel can better load and unload the cardboard, without putting their hands between the dies for loading and unloading, greatly improving the safety and efficiency of the cardboard of the carton during convex pattern pressing.

[0022] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with the specific embodiments.

[0023] In order to improve the safety and efficiency of the cardboard of the paper box during embossing, as Figures 1-5As shown in the figure, a embossing die for carton processing according to the present utility model includes a die base 1, an upper punch 3, a lower die part 6 and a reciprocating assembly 7. Support columns 2 are respectively connected to the top corners of the die base 1. The corners of the upper punch 3 are sleeved on the support columns 2. The top of the support columns 2 is connected to a top plate 4. A cylinder 5 is installed on the top of the top plate 4. The output end of the cylinder 5 is connected to the top of the upper punch 3.

[0024] When in use, the die base 1, the upper punch 3, the lower die part 6 and the reciprocating assembly 7 are used to provide a pressing die for the embossing operation of carton processing, which can automatically replace the lower die alternately after each pressing. During the pressing of the upper group of cardboard, the cardboard to be pressed next time can be placed on the other group of dies in advance, so that the operator can load and unload the cardboard better without putting the hand into the dies, greatly improving the safety and efficiency of the cardboard of the carton during embossing.

[0025] The lower die part 6 is located between the die base 1 and the upper punch 3. The reciprocating assembly 7 is connected to the upper punch 3, the die base 1 and the lower die part 6.

[0026] The present utility model further includes that the lower die part 6 includes a slide rail 61. A slider 62 is slidably connected to the top of the slide rail 61. The top of the slider 62 is connected to a mounting plate 63. Two ends of the top of the mounting plate 63 are connected with a first female die 64 and a second female die 65 for alternately replacing below the upper punch 3. The bottom of the slide rail 61 is fixedly riveted to the die base 1 by bolts.

[0027] When in use, the first female die 64 and the second female die 65 cooperate with the upper punch 3 for the embossing of the carton, and are alternately replaced by the sliding of the slider 62.

[0028] The present utility model further includes that the reciprocating assembly 7 includes a gear 71 rotatably connected to the side corners of the die base 1 through bearings. A first synchronous pulley 73 is installed in the gear 71 through a ratchet 72. A rack 74 meshing with the gear 71 is connected to the side corners of the upper punch 3.

[0029] When in use, the gear 71 is installed on the side of the die base 1 through bearings and meshes with the rack 74 on the side of the upper punch 3 to drive the rotation of the gear 71 by the up and down movement of the upper punch 3, and the ratchet 72 is used to ensure that the gear 71 can only drive the first synchronous pulley 73 to rotate in one direction.

[0030] A second synchronous pulley 75 is rotatably connected to the side of the die base 1 through a bearing. The second synchronous pulley 75 is connected to the first synchronous pulley 73 by a synchronous belt. A reciprocating lead screw 76 is installed at the center of the second synchronous pulley 75. The tail end of the reciprocating lead screw 76 is rotatably connected to the die base 1 through a bearing;

[0031] A thread sleeve 77 is sleeved on the reciprocating lead screw 76 in a threaded manner, and the top of the thread sleeve 77 is connected to the bottom of the mounting plate 63 through a vertical rod 66.

[0032] During use, the second synchronous pulley 75 is connected to the first synchronous pulley 73 through a synchronous belt to transmit the rotational motion to the reciprocating lead screw 76. The reciprocating lead screw 76 rotates on the die holder 1 and is in threaded cooperation with the thread sleeve 77 to convert the rotational motion into a linear motion, causing the mounting plate 63 and the first female die 64 and the second female die 65 on the top to move horizontally, realizing the alternate replacement between the first female die 64 and the second female die 65 at the bottom of the upper punch 3.

[0033] When the present utility model is in use, the cardboard of the carton to be embossed is placed through the first female die 64 and the second female die 65. During pressing, the air cylinder 4 drives the upper punch 3 to descend to emboss the cardboard on one set of female dies. The rack 74 moves downward accordingly. Due to the setting of the ratchet wheel 72, at this time, the gear 71 meshing with the rack 74 rotates independently by itself and does not drive the first synchronous pulley 73 to rotate. After the air cylinder 4 retracts to drive the upper punch 3 to move upward and the rack 74 moves upward accordingly, the gear 71 rotates. At this time, the ratchet wheel 72 drives the first synchronous pulley 73 to rotate, and the second synchronous pulley 75 rotates accordingly and drives the reciprocating lead screw 76 to rotate. Moreover, when the rack 74 moves upward once to drive the gear 71 to rotate, the thread sleeve 77 drives the mounting plate 63 to complete one movement. When the rack 74 moves upward again to drive the gear 71 to rotate, based on the double threads on the reciprocating lead screw 76, the thread sleeve 77 drives the mounting plate 63 to move back. Repeating this way, the first female die 64 and the second female die 65 on the mounting plate 63 can be alternately replaced in cooperation with each upward movement of the upper punch 3. Thus, the processing personnel can alternately take and load materials on the first female die 64 or the second female die 65 that is moved out from below the upper punch 3 each time, greatly reducing the time wasted during each pressing process due to inability to work, and improving the efficiency and safety of the embossing operation of the cardboard for carton processing.
