Description

Technical Field

[0001] The utility model relates to the technical field of carton processing equipment, and particularly relates to a grooving device for carton production. Background Technique

[0002] During the processing of cartons, it is often necessary to groove the cartons, and a grooving device is required.

[0003] Referring to the existing authorized announcement number CN 213798322 U, "A Grooving Device for Carton Production", through the cooperation of a chute body, a slider, a lifting rod, a rotating disk, a transmission rod and a rotating block, the fixed block is pressed down to groove the cardboard placed on the grooving block. Through the cooperation of a third rotating rod, a first gear, a second gear, a third gear and a fourth gear, when the fixed block is pressed down for grooving, the toothless part of the second gear idles with the first gear. When the lifting rod rises, the toothed part of the second gear drives with the first gear. Through two groups of transmission rods, the grooved cardboard on the grooving block is sent out, and the non-grooved cardboard is sent in to continue processing the cardboard, solving the problem that some grooving devices on the current market manually feed the materials, groove through the grooving device, and then manually pick up the materials. Such a device has low processing efficiency, is time-consuming and laborious, and cannot produce cartons in large quantities and quickly.

[0004] However, in the actual use process of the above-mentioned existing patent, during the grooving operation, the grooving block reciprocates up and down along the vertically arranged chute body to achieve the grooving effect. Such a grooving method requires intermittent conveying of the cartons to achieve a better grooving effect. The intermittent conveying method will affect the conveying efficiency of the cartons. If the cartons are not conveyed in an intermittent manner, it will have an adverse impact on the edge of the groove cut by the grooving block during the grooving operation. At the same time, the grooving block used for grooving is not convenient for quick disassembly, replacement and position adjustment, which is not conducive to the operation when the grooving block is excessively worn and needs to be replaced or maintained. Therefore, the utility model proposes a grooving device for carton production to solve the above problems.

[0005] The information disclosed in this background technical section is only intended to enhance the understanding of the overall background of the utility model, and should not be regarded as an admission or any form of suggestion that this information constitutes prior art already known to those of ordinary skill in the art.

Figure 1 and Figure 2 The state shown is adjusted and limited. After the adjustment is completed, the carton is transported by the conveyor belt 2 so that the carton is transported to the position below the grooving knife. At the same time, the U-shaped plate 31 is controlled to move downward by the electric cylinder 3, and the drive motor 33 is started to control the reciprocating screw 32 to drive the strip plate 4 to move to the right, so that the grooving knife and the carton remain in a relatively static state and the grooving operation is realized. After one grooving operation is completed, the electric cylinder 3 controls the U-shaped plate to separate the grooving knife from the carton and reset it to the left after separation, and then the next grooving operation can be performed.
