Description

Technical Field

[0001] This utility model relates to the field of cardboard box production technology, specifically to an indentation device for cardboard box production. Background Technology

[0002] Corrugated cardboard is the main material for packaging cartons. Due to the inherent difficulty in bending corrugated cardboard, when bending the cut cardboard into cartons, it is necessary to first press creases into the cardboard using a creasing machine. Then, workers bend the cardboard along the creases to fold it into a carton. A Chinese utility model patent (publication number: CN221623144U) discloses a cardboard creasing device. By placing multiple cardboards into a guide cylinder, the first and second rotating rods drive two sets of rollers to rotate synchronously. The two sets of rollers drive the transmission belt to rotate, and the transmission belt drives the push plate on it to rotate. The push plate pushes the bottom cardboard to move horizontally, and the cardboard moves from the discharge trough to the base, thus realizing the feeding of cardboard.

[0003] However, the above-mentioned device still has some shortcomings in use: Specifically, since the size of the discharge chute is fixed, in actual production, the thickness of the cardboard used in carton production varies. When the thickness of the cardboard to be processed changes, the fixed-size discharge chute cannot guarantee that cardboard of different thicknesses can be discharged smoothly. Therefore, in view of the above situation, a creasing device for carton production is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a creasing device for carton production. Through the structural design of rectangular groove, threaded rod, U-shaped frame and baffle, the opening size of the discharge port can be flexibly adjusted according to the thickness of the cardboard, and the processing of cardboard of different thicknesses can be quickly switched. This solves the problem in the prior art that it is difficult to ensure that cardboard of different thicknesses can be discharged smoothly when the discharge groove of fixed size is fixed.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model relates to a creasing device for carton production, comprising a support frame, a conveying mechanism on the support frame, a creasing mechanism on one side of the support frame, a guide frame on the top of the support frame, and an adjustment mechanism on the guide frame.

[0007] Furthermore, a discharge port is provided on one side of the guide frame, and a groove is also provided on the outer surface of the guide frame.

[0008] Furthermore, the adjustment mechanism also includes mounting blocks and guide rods. There are four mounting blocks, which are rectangular and fixed to the outer surface of the guide frame. Adjacent mounting blocks are fixedly connected by guide rods.

[0009] Furthermore, a connecting block is slidably fitted on the guide rod, and one end of the connecting block is fixed to one side of one of the baffles.

[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] Please see Figure 1-5 This utility model provides a technical solution: a creasing device for carton production, including a support frame 1, a conveying mechanism 2 on the support frame 1, a creasing mechanism 3 on one side of the support frame 1, and a certain gap between the support frame 1 and the creasing mechanism 3.

[0023] The conveying mechanism 2 and the creasing mechanism 3 have the same composition as those in the comparative patent for conveying paperboard and creasing paperboard, respectively, and will not be described in detail here.

[0024] The top of the support frame 1 is provided with a guide frame 4, a discharge port is provided on one side of the guide frame 4, a groove is provided on the outer surface of the guide frame 4, and an adjustment mechanism 5 is provided on the guide frame 4.

[0025] The guide frame 4 has a rectangular frame structure with an inner cavity for placing cardboard, and openings at the top and bottom.

[0026] The discharge port has a certain height reserved. The discharge port can be adjusted by the adjustment mechanism 5, thereby changing the distance between the baffle 505 and the conveying mechanism 2 to form the actual size of the discharge port, so as to meet the effective discharge of paperboard of different thicknesses.

[0027] The adjusting mechanism 5 includes a rectangular groove 501 opened on the guide frame 4. The guide frame 4 has a threaded hole 502 that communicates with the rectangular groove 501. A threaded rod 503 is threadedly fitted on the threaded hole 502. One end of the threaded rod 503 passes through the threaded hole 502 and is rotatably connected to a U-shaped frame 504. Two baffles 505 are fixed at both ends of the bottom of the U-shaped frame 504. One side of each baffle 505 contacts the guide frame 4.

[0028] One of the baffles 505 has extension plates 506 fixed at both ends of its top, and the extension plates 506 are attached to the inner wall of the guide frame 4.

[0029] Specifically, the extension plate 506 makes it easier to place cardboard in the inner cavity of the guide frame 4, reducing the problem of tilting during placement.

[0030] In this embodiment, when it is necessary to adjust the size of the discharge port of the guide frame 4 according to the thickness of the cardboard to be processed, the operator can rotate the threaded rod 503 to raise and lower the threaded rod 503. During the raising and lowering of the threaded rod 503, the U-shaped frame 504 will be raised and lowered, thereby causing the two baffles 505 fixed at the bottom of the U-shaped frame 504 to complete the raising and lowering operation simultaneously. This can realize the change of the size of the discharge port on the guide frame 4, thereby meeting the discharge requirements of cardboard of different thicknesses.

[0031] As a further explanation of the above embodiments, the adjustment mechanism 5 also includes mounting blocks 507 and guide rods 508. There are four mounting blocks 507, which are rectangular and fixed on the outer surface of the guide frame 4. Adjacent mounting blocks 507 are fixedly connected by guide rods 508.

[0032] A connecting block 509 is slidably fitted on the guide rod 508, and one end of the connecting block 509 is fixed to one side of one of the baffles 505.

[0033] The connecting block 509 has a through hole, which slides with the guide rod 508.
