Description

Technical Field

[0001] This utility model relates to the technical field of cardboard box creasing devices, and in particular to a cardboard box creasing device for cardboard box production. Background Technology

[0002] Cardboard boxes need to be folded during manufacturing and use. The creases pressed by the creasing device on the cardboard allow the box to be folded accurately according to the predetermined position. This greatly improves the efficiency and precision of cardboard box folding and ensures that all sides of the box can be folded together smoothly to form a neat three-dimensional shape. In order to ensure the effect of cardboard box creasing, a special creasing device is generally used to process the cardboard box.

[0003] A search of Chinese patent CN221641915U reveals a cardboard box creasing device for cardboard box production. The device includes a base with support feet at each of the four corners of the base's bottom. Symmetrical limiting grooves are formed along the two longer edges of the base's top, and a cavity is formed between these grooves at the top of the base. This invention, through its design, utilizes two fixed blocks that move outside two threaded rods to move two support plates away from each other, facilitating adjustment according to the required dimensions of different cardboard boxes. Rotating the fastening bolts lowers the limiting plates to fix the cardboard box and prevent displacement during creasing. An electric telescopic rod extends and lowers the pressure plate, bringing it into contact with the top edge of the support plates to creasing the cardboard box. This effectively solves the problem of traditional cardboard box creasing devices being inconvenient for adjusting to cardboard boxes of different sizes and crease positions.

[0004] However, in implementing the relevant technology, the following problems were found with the above-mentioned creasing device: Although the existing technology can process cartons of different sizes, it is inconvenient to position cartons of different widths when processing cartons of different widths, which affects the processing efficiency. Moreover, the existing technology requires the fastening bolts to be rotated in advance to drive the limiting plate to descend in order to fix the cartons, which is inconvenient to operate. Based on this, this utility model designs a carton creasing device for carton production to solve the above problems. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides, for example Figure 1-4The diagram shows a cardboard creasing device for cardboard box production, comprising a support frame 1. Linear guide rails 2 are mounted on the top outer wall of the support frame 1. The linear guide rails 2 are connected to support base plates 3 via sliders. Two support base plates 3 are symmetrically arranged above the support frame 1. A push rod support plate 4 is mounted on one side wall of each support base plate 3. An electric push rod 5 is mounted on the top outer wall of the push rod support plate 4. A lower pressure plate 6 is connected to the output end of the electric push rod 5. Guide side plates 7 are mounted on one side wall of the lower pressure plate 6. A guide shaft 8 is slidably engaged on the guide side plate 7. A fixed pressure plate 9 is mounted on one end of the guide shaft 8. A support spring 12 is provided on the side wall of the guide shaft 8. During cardboard box processing, the cardboard is first placed on the support... On the support base plate 3, the lower pressure plate 6 is lowered by the electric push rod 5. First, the fixed pressure plate 9 contacts the carton, which can drive the support spring 12 to compress. The support spring 12 abuts against the fixed pressure plate 9, so that the fixed pressure plate 9 can abut against the carton, thereby fixing the carton. Then the lower pressure plate 6 contacts the carton again to crease the carton. This device can fix the carton conveniently and quickly when creased, which helps to improve the ease of use of the device. A limiting base plate 10 is installed on the bottom outer wall of the support base plate 3. A guide crossbar 13 is installed on one side wall of the limiting base plate 10, and a limiting block 11 is installed on the other side wall of the limiting base plate 10. A sliding engagement device for limiting the carton is attached to the guide crossbar 13. The limiting component 14 includes a support block 1401, which is slidably engaged with a guide crossbar 13. A limiting frame 1402 is installed on the bottom outer wall of the support block 1401. Guide rods 1403 are installed on one side wall of the limiting frame 1402, and a guide base plate 1404 is slidably engaged with the guide rods 1403. A fixing block 1406 is installed on one side wall of the guide base plate 1404, and the fixing block 1406 is slidably engaged with the limiting frame 1402. A pressing spring 1405 is provided on the side wall of the guide rods 1403 for pressing the guide base plate 1404. When it is necessary to process cartons of different widths, the fixing block 1406 can be driven by pulling the limiting frame 1402 forward. 406 passes through the limiting block 11, and each time the fixed block 1406 passes through a limiting block 11, the guide plate 1404 moves through the tightening spring 1405, so that the fixed block 1406 can pop out again, so that the limiting block 11 behind it can limit the fixed block 1406, thus preventing the limiting frame 1402 from retracting. After the limiting frame 1402 is adjusted to a suitable position, the carton can be limited by pressing against the limiting frame 1402, and by pulling the guide plate 1404, the limiting block 11 can no longer limit the fixed block 1406. Then the limiting frame 1402 can be moved backward. Therefore, this device can conveniently and quickly limit cartons of different widths during production.

[0023] In this embodiment, a fixed base 16 is fixedly installed on the top lower surface of the support frame 1. A bidirectional threaded rod 17 is rotatably connected to the fixed base 16. Supporting vertical plates 18 are respectively connected to the threads on the outer surface of the bidirectional threaded rod 17. The supporting vertical plates 18 are slidably engaged with the support frame 1 and connected to the support base plate 3. A drive motor 19 is installed on the top lower surface of the support frame 1. A drive pulley 20 is connected to the output end of the drive motor 19. A driven pulley 21 is provided on the side wall of the bidirectional threaded rod 17. The driven pulley 21 is connected to the drive pulley 20 through a transmission belt. The drive motor 19 drives the drive pulley 20 at its output end to rotate, thereby driving the bidirectional threaded rod 17 to rotate. The bidirectional threaded rod 17 can simultaneously drive the supporting vertical plates 18 to move, thereby adjusting the position of the support base plate 3, so that the device can process cartons of different lengths.

[0024] In this embodiment, guide posts 15 are respectively installed on the top outer wall of the lower pressure plate 6. The guide posts 15 are slidably engaged with the push rod support plate 4. The guide posts 15 can guide the lower pressure plate 6, which helps to improve the stability of the lower pressure plate 6 when it moves up and down.

[0025] Working principle of this utility model: This utility model is a cardboard creasing device for cardboard box production. By pulling the limiting frame 1402 forward, the fixing block 1406 can be driven to pass through the limiting block 11. Each time the fixing block 1406 passes through a limiting block 11, the top spring 1405 can drive the guide plate 1404 to move, so that the fixing block 1406 can pop out again, so that the limiting block 11 behind it can limit the fixing block 1406, thereby preventing the limiting frame 1402 from retracting. After the limiting frame 1402 is adjusted to a suitable position, the cardboard box can be placed on the support base plate 3. By pressing the cardboard box against the limiting frame 1402, the cardboard box can be limited. Therefore, this device can conveniently and quickly limit cardboard boxes of different widths during production.

[0026] By placing the carton on the support base plate 3, and then driving the lower pressure plate 6 to descend via the electric push rod 5, the fixed pressure plate 9 first contacts the carton, while the support spring 12 is compressed, so that the support spring 12 can drive the fixed pressure plate 9 to press against the carton, thereby fixing the carton. Then the lower pressure plate 6 contacts the carton again to crease it. Therefore, this device can conveniently and quickly fix the carton when creasing it.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
