Description

Technical Field

[0001] The utility model relates to the technical field of cardboard slotting, in particular to a carton slotting machine. Background Art

[0002] At present, the most widely used packaging products in our daily life are cartons. According to different materials, cartons include corrugated boxes, single-layer cardboard boxes, etc., with various models and specifications. Commonly used cartons are three-layer and five-layer, and seven-layer is less used. Each layer is divided into lining paper, corrugated paper, core paper, and face paper. The lining and face paper are tea board paper and kraft paper, and the core paper is corrugated paper. The color and feel of various papers are different, and the paper produced by different manufacturers (color, feel) is also different.

[0003] In order to facilitate workers to fold cardboard into box bodies, cartons need to be slotted and crimped during the production process. Slotting and crimping require the use of a carton slotting machine. For example, a Chinese utility model patent with publication number CN211279966U and the name of the patent "A knife holder axial adjustment mechanism for a carton slotting machine" discloses an axial adjustment mechanism for the knife holder of a carton slotting machine. After adjusting the axial direction, the knife holder body is relatively fixed to the rotating shaft through bolts passing through the first punching holes, the second punching holes and the third punching holes on the upper and lower sides. Bolts are inserted into the first punching holes, the second punching holes and the third punching holes on the left and right sides to make the knife holder and the rotating shaft after adjusting the axial direction more firmly fixed. The rotating shaft rotates in a fixed housing connected to the knife holder body through a turntable sleeved on the outer wall for axial adjustment. It does not directly contact the fixed housing, and a bearing is installed at the connection between the rotating shaft and the knife holder body, so that the rotating shaft and the knife holder body will not be worn after long-term use.

[0004] However, there are defects in the above structure. Specifically, when the tool holder of the carton slotting machine moves axially, the upper and lower slotting tool holders cannot be moved at the same time, and the positions of the crimping wheel and the pre-pressing wheel cannot be changed at the same time. They need to be moved one by one, and the staff needs to realign them after moving, which not only has the risk of misalignment and damage to the tool, but also reduces work efficiency.

[0005] Based on the above reasons, it is necessary to improve the existing technology. Utility Model Content

DETAILED DESCRIPTION

[0023] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0024] See also Figure 1-5The utility model provides a carton slotting machine, including a machine body 1, the machine body 1 includes a first cutting mechanism 2, a pre-pressing mechanism 3, a pressing mechanism 4, and a second cutting mechanism 5 which are arranged in sequence according to the cardboard conveying direction, the first cutting mechanism 2 includes a first cutting wheel 20, the pre-pressing mechanism 3 includes a pre-pressing wheel 30, the pressing mechanism 4 includes a pressing wheel 40, and the second cutting mechanism 5 includes a second cutting wheel 50, the machine body 1 includes a guide rail 10 which is transversely arranged on the machine body 1, at least four mounting plates 11 which are movably arranged on the guide rail 10, and a driving mechanism 6 which drives the mounting plate 11 to slide on the guide rail 10 and self-lock to a fixed position, and each of the mounting plates 11 is respectively provided with the first cutting wheel 20 and the first cutting wheel 50 on the front and rear sides. Two cutting wheels 50, the pre-pressing wheel 30 and the crimping wheel 40 are arranged between the first cutting wheel 20 and the second cutting wheel 50, a driving wheel 100, a driven wheel 200 and a tensioning device 300 are arranged on each of the mounting plates 11, and the tensioning device 300 tensions the driving wheel 100, the driven wheel 200, the pre-pressing wheel 30 and the crimping wheel 40 together, a main shaft 12, a first transmission shaft 13 and a second transmission shaft 14 are movably arranged on the body 1, the main shaft 12 passes through each driving wheel 100 and is driven by a driving motor, the first transmission shaft 13 passes through each first cutting wheel 20 and is driven by a driving motor, and the second transmission shaft 14 passes through each second cutting wheel 50 and is driven by a driving motor.

[0025] In the above structure, the driving mechanism can move the mounting plate. When the position of the mounting plate changes, the positions of the first cutting wheel, the wire pressing wheel, the pre-pressing wheel and the second cutting wheel change synchronously without the need for staff to realign. When the main shaft rotates, the tensioning device transmits power to rotate the driven wheel, the wire pressing wheel and the pre-pressing wheel. The wire pressing wheel and the pre-pressing wheel can rotate without being driven by a rotating shaft, thereby reducing the use of a rotating shaft and saving costs.

[0026] Specifically, a rubber wheel 400 is movably provided on the upper end of the mounting plate 11, which corresponds to the positions of the first cutting wheel 20, the pre-pressing wheel 30, the creasing wheel 40 and the second cutting wheel 50. The function of the rubber wheel is to provide a forward force to the carton raw material so that the carton can pass through the first cutting wheel, the creasing wheel, the pre-pressing wheel and the second cutting wheel smoothly. The use of rubber material can prevent the upper wheels from scratching the carton raw material and the friction of rubber is large.

[0027] Specifically, the guide rail 10 and each mounting plate 11 are connected via a slider 500 . The use of the guide rail and the slider has the advantages of high precision, high stability, high load capacity, stable reliability and long service life.

[0028] Specifically, the tensioning device 300 is a synchronous belt. Compared with other transmission parts, the synchronous belt has the advantages of accurate transmission ratio, no slippage, small force on the shaft, compact structure, good oil resistance, wear resistance, aging resistance, low noise and high transmission efficiency.

[0029] Specifically, the driving mechanism 6 is a transversely arranged screw-nut mechanism, which can drive the nut to rotate by a servo motor, so that the mounting plate can move left and right on the screw, and can self-lock in a fixed position.

[0030] Specifically, the screw-nut mechanism includes a pair of screws corresponding to the left and right positions, a nut 600 movably arranged on each of the screws, and a transmission gear 700 arranged between the left and right nuts 600 and driven by a driving motor. Selecting the left and right screw-nut mechanisms can balance the force of the structure, increase the stability of the structure and make it look more beautiful.

[0031] The above are only preferred implementations of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
