Description

Technical Field

[0001] This utility model relates to the field of packaging box production technology, and in particular to an indentation device for the production of polymer packaging boxes. Background Technology

[0002] Packaging boxes are mainly designed for easy transportation, loading, unloading, and storage. They are generally made of honeycomb cardboard, which is made by stamping, cutting, and gluing honeycomb paperboard. Paper corner protectors are glued to the joints of the paperboard for reinforcement. They can be designed in different configurations such as integral, modular (detachable), and integrated base tray according to actual needs, which makes them easier to handle and unload. During the production process of packaging boxes, the honeycomb paperboard needs to be crimped to facilitate subsequent operations.

[0003] For example, Chinese Patent Publication No. CN219618604U discloses a creasing device for packaging box production, including: an operating table located at the center of the device, and creasing components disposed on both sides of the operating table. The aforementioned disclosure improves practicality by adjusting the cross-arranged lead screws in conjunction with rotatable creasing wheels, allowing the creasing position to be changed as needed. Compared to traditional creasing devices, this device adds fixing components on both sides of the operating table. Through the extension and contraction of springs and the cooperation of pressure plates, the honeycomb cardboard can be fixed to the surface of the operating table, preventing deviations during the creasing process and improving production efficiency. However, this patent only provides single-sided creasing; double-sided creasing requires double creasing of the cardboard, reducing packaging box processing efficiency and hindering long-term use and widespread adoption. Therefore, those skilled in the art have provided a creasing device for polymer packaging box production to solve the problems mentioned in the background art. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6 This utility model provides a technical solution for an indentation device used in the production of polymer packaging boxes: it includes a base plate 1 and a support plate 101 fixedly installed on the rear end of the outer top surface of the base plate 1. A top plate 102 is fixedly installed on the outer top surface of the support plate 101. An automatic push rod 103 is fixedly installed on the outer top surface of the top plate 102. Sliding rods 104 are fixedly installed at the left and right ends of the outer bottom surface of the top plate 102. One end of the two sliding rods 104 is fixedly connected to the base plate 1. A movable plate 105 is provided on the outer bottom surface of the top plate 102 and between the two sliding rods 104. A processing component 2 for indenting one side of the packaging box is provided below the movable plate 105. The processing component 2 includes a sliding sleeve on the two... The straight sleeves 201 on the outer peripheral surface of the slide rod 104 are fixedly connected to the outer walls of the left and right sides of the moving plate 105. The output end of the automatic push rod 103 extends to the outer bottom surface of the top plate 102 and is fixedly connected to the moving plate 105. A horizontal slide groove 202 is provided at the right end of the outer bottom surface of the moving plate 105. A block is provided inside the horizontal slide groove 202. One end of the block extends to the center of the outer bottom surface of the moving plate 105 and is fixedly connected to a straight plate 203. An indentation protrusion 204 is fixedly installed at the center of the outer bottom surface of the straight plate 203. At the same time, the block is threadedly connected to the moving plate 105 through a positioning screw 205. In use, the automatic push rod 103 is controlled and activated to drive the moving plate 105 to move downward along the outside of the two slide rods 104, thereby performing a denting operation on one side of the packaging box through the denting protrusion 204. When different dents need to be dented on packaging boxes of different shapes, the positioning screw 205 can be turned directly to release the fixed relationship between the block and the moving plate 105. Then, the straight plate 203 can be moved along the inside of the horizontal slide groove 202 and removed, which makes it easy to replace and improves its practicality.

[0029] A slide rail 106 is symmetrically installed on the front end of the outer top surface of the base plate 1. Connecting blocks are slidably connected to the outer top surfaces of both slide rails 106. A U-shaped seat 107 is fixedly installed on the outer top surface of the two connecting blocks. A processing component 2 3 for indenting the other end of the packaging box is provided on the outer top surface of the U-shaped seat 107. The processing component 2 3 includes a threaded rod 301 rotatably installed at the center of the outer top surface of the U-shaped seat 107. One end of the threaded rod 301 is rotatably connected to a lifting plate 302, while the other end extends to the outer bottom surface of the U-shaped seat 107 and is fixedly installed with a knob. A horizontal sliding groove 2 303 is provided on the right end of the outer top surface of the lifting plate 302. Inside the second 303 is a second square block. One end of the second square block extends to the center of the outer top surface of the lifting plate 302 and is fixedly connected to a second straight plate 304. A recessed rectangular slot 305 is opened at the center of the outer top surface of the second straight plate 304. An indentation protrusion 306 is fixedly installed at the center of the bottom surface of the rectangular slot 305. Meanwhile, the second square block is threadedly connected to the lifting plate 302 through a positioning screw 307. Guide rods 308 are slidably sleeved on the left and right ends of the outer top surface of the U-shaped seat 107. One end of the two guide rods 308 is fixedly connected to the lifting plate 302, while the other end extends to the outer bottom surface of the U-shaped seat 107. First, place the packaging box to be processed on the second indentation protrusion 306 in the rectangular slot 305. Then, push the U-shaped seat 107 to move it along the two slide rails 106 to facilitate the subsequent indentation operation on the other end of the packaging box. Afterward, turn the knob to drive the threaded rod 301 to rotate, and adjust the height of the lifting plate 302 with the assistance of the guide rod 308 to improve the effect of the subsequent indentation operation. At the same time, turn the positioning screw 307 to release the fixed relationship between the second block and the lifting plate 302. Then, move the second straight plate 304 along the inner side of the second horizontal slide groove 303 and take it out to facilitate replacement, thereby further improving its practicality.

[0030] Ear seats 108 are fixedly installed on the left and right ends of the rear outer wall of the U-shaped base 107. Square sleeves 109 are slidably sleeved on the outer circumferential surfaces of the two slide rods 104. Ear seats 110 are fixedly installed on the front outer walls of the two square sleeves 109. The two ear seats 108 and ear seats 110 are rotatably connected to each other through a linkage plate 111. Return springs 4 are sleeved on the outer circumferential surfaces of the two slide rods 104. One end of the two return springs 4 is fixedly connected to the outer bottom surface of the square sleeve 109, and the other end is fixedly connected to the outer top surface of the base plate 1. By pushing the square sleeve 109 downward, the return springs 4 are squeezed, which in turn drives the U-shaped base 107 to move through the linkage plate 111, thereby achieving the effect of double-sided embossing of the packaging box. At the same time, with the assistance of the return springs 4, the U-shaped base 107 can be pushed out after the packaging box is processed, which facilitates the subsequent removal of the packaging box.

[0031] The working principle of this utility model is as follows: When using it, the packaging box to be processed is first placed on the indentation protrusion 306 inside the rectangular slot 305.

[0032] Simultaneously, the automatic push rod 103 is activated to drive the moving plate 105 to move downward along the outside of the slide rod 104, so that the straight sleeve 201 and the square sleeve 109 abut against each other and push the square sleeve 109 downward, so that the linkage plate 111 drives the U-shaped seat 107 to move along the two slide rails 106 to directly below the first embossing protrusion 204, so that the first embossing protrusion 204 and the second embossing protrusion 306 can simultaneously perform embossing operations on the upper and lower sides of the packaging box.

[0033] Meanwhile, after the indentation work is completed, the automatic push rod 103 is activated again to drive the moving plate 105 to move upward, and the U-shaped seat 107 is pushed out under the elastic deformation of the return spring 4, so as to facilitate the removal of the processed packaging box.

[0034] Finally, simply turn the positioning screw 1 205 and positioning screw 2 307 to disassemble the straight plate 1 203 and straight plate 2 304, so as to facilitate the replacement of the indentation bump 1 204 and indentation bump 2 306 as needed, thereby facilitating the processing of packaging boxes of different shapes.

[0035] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
