Description

Technical Field

[0001] The utility model relates to the technical field of carton production devices, in particular to a creasing device used in the production of packaging cartons. Background Art

[0002] Packaging cartons are primarily used for product packaging. They are typically produced by fastening the ends of creased carton panels together at intervals using a nailing mechanism to create the finished packaging carton. (The carton's lower and upper ends, as well as its side ends, each have a creased base, cover, and side connecting panels. The two creased cardboard panels on each base and cover are fastened together using pre-set clips. After the product is packaged, the base and cover are secured with tape.)

[0003] Before the production of packaging cartons, the corresponding positions (the lower and upper ends and side ends of the packaging cartons) need to be creased horizontally at 90 degrees. The existing packaging carton production crease equipment generally includes a workbench and an electric or hydraulic press plate. During operation, the carton board is placed on the workbench (the front side has a limit seat, which mainly limits the front end of the carton board and facilitates the downward pressing operation of the press plate). Then the press plate is controlled to move downward and the corresponding position of the carton board is pressed horizontally into the "L"-shaped crease groove on the workbench, thereby forming a crease at the corresponding position of the carton board. Although the existing packaging carton crease equipment meets the production needs to a certain extent, it is limited by the structure and still has the following technical shortcomings. First: When the pressing plate moves downward to crease the carton board, the downward distance is based on manual control or control of the control system (such as PLC). When the staff is inexperienced or the internal software of the control system has an abnormality, the downward distance of the pressing plate is too large or too small, which will have an adverse effect on the quality of the crease of the carton board (if the downward distance of the pressing plate is too small, the crease cannot be effectively formed, and when the downward distance of the pressing plate is too large, there is a probability of damaging the corresponding position of the carton board). Second: The position of the crease groove and the pressing plate of the workbench is fixed, and the front and rear widths of the workbench are also fixed, that is, only carton boards of corresponding width and corresponding position can be creased, and the application has limitations (if the front and rear widths of the creased carton board are relatively short, a workbench with too large a front and rear width will cause inconvenience to the staff's operation). In summary, it is particularly necessary to provide a packaging carton crease production equipment that can effectively control the crease distance and crease force, and can conveniently adjust the width of the workbench. Utility Model Content

The front and rear widths of the movable table can also be adjusted back and forth as needed to adapt to creasing operations of carton boards with different front and rear widths.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] 7.

[0007] Furthermore, the upper end of the flat plate of the workbench and the upper end of the movable table are in the same plane, and the movable table and the flat plate at the upper end of the workbench have the same width.

[0008] Furthermore, the rear end of the movable table top has an indentation groove in the transverse direction, and the transverse length of the indentation groove is consistent with the length of the pressing plate, and the front-to-back width of the pressing plate is smaller than the inner front-to-back width of the indentation groove.

[0009] Furthermore, the indentation groove and the lower end of the pressing plate are located in a vertical plane.

[0010] Furthermore, the adjusting sub-mechanism includes a wire tube, a bearing seat A, and a screw rod A. The screw rod A and the wire tube are connected together by threads.

[0011] Furthermore, a limit seat is laterally fixedly installed on the front side end of the movable table.

The present invention brings convenience to the staff and correspondingly improves work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

Figure 4 All electrical components are mature industrial technologies, and this application does not elaborate on the working principles.

[0019] Figure 1-Figure 4As shown in the figure, after the AC 220V power supply enters the power input terminal of the power module Q1, the 3rd and 4th pins of the power module Q1 output a stable DC 24V power supply which enters the power input terminal of the control circuit and the power switch S1. The working process of this novel method is as follows. (1) According to the front and back width of the carton board, it is necessary to adjust the front and back width of the movable table 2 and the workbench flat plate 101 to be larger or smaller. When the staff rotates the two handles 35 clockwise or counterclockwise with both hands (the linear bearing 34 is the guide for the front and back movement of the movable table 2), the rear side of the screw rod 32 rotates along the inner ring of the bearing seat 33, the outer thread of the screw rod 32 acts on the inner thread of the thread seat, and the front end of the screw rod 32 drives the thread seat 31 to move forward or backward. In this way, the movable table 2 will move synchronously with the front end of the workbench flat plate 101 to expand or shrink, and then the front and back width between the workbench and the movable table will increase or decrease; stop rotating the handle after it is in place. (2) When the staff rotates the two handles A434 clockwise or counterclockwise by hand (the linear bearing A432 guides the forward and backward movement of the connecting plate 44), the rear side of the screw rod A433 rotates along the inner ring of the bearing seat A432, and the external thread of the screw rod A433 acts on the internal thread of the wire tube 431, and the wire tube 431 drives the connecting plate 44 and the pressure plate 21 to move forward or backward. After the handle A433 is in place, the rotation is stopped (the indentation groove 21 and the lower end of the pressure plate 42 are in a vertical plane). Through the above, the new model can adjust the movable table, the electric push rod and the pressure plate to move forward or backward respectively. In this way, since the front and rear width of the movable table can be adjusted forward and backward according to needs, it can facilitate the crease operation at different positions of the carton boards with different front and rear widths. (3) When the staff member turns the power switch S1 handle to the left, the 1st and 2nd pins and the 3rd and 4th pins of the power switch S1 are connected respectively, so that the positive and negative power input terminals of the electric push rod M1 are energized and its push column drives the pressure plate 42 upward (the linear bearing A plays a guiding and limiting role), and the lower end of the pressure plate 42 and the indentation groove 21 are spaced apart and the power switch S1 is turned off; then the staff member places the part of the carton board that needs to be creased horizontally on the upper end of the indentation groove 21 (the front end of the carton board is located at the lower end of the limit seat), and the staff member turns the power switch S1 handle to the right, and the 1st and 2nd pins and the 5th and 6th pins of the power switch S1 are connected respectively, so that the negative and positive power input terminals of the electric push rod M1 are energized and its push column drives the pressure plate 42 downward, so that the lower end of the pressure plate will enter the "L"-shaped indentation groove (the depth is only about 2 cm), pressing down the indentation groove of the carton board to form a 90-degree indentation (the rear end of the carton board is upturned).In step (3), when the pressing plate 42 is pressed down to contact the upper end of the carton board, if the pressure is insufficient, the force acting on the force surface of the pressure sensor Q2 is small, and the voltage signal outputted from its pin 3 is relatively low. In this way, the voltage signal outputted from the pin 3 of the pressure sensor Q2 is divided by the resistors R1 and R2 and enters the base of the transistor VT, which is lower than 0.7V. The transistor VT will not be turned on, and the relay K will not be energized and attracted. Then, the 24V power supply continues to enter the negative and positive power input terminals of the electric push rod M through the two control power input terminals and the two normally closed contact terminals of the relay K, and the electric push rod M continues to be energized to push the pressing plate downward and perform indentation operations on the carton board. The pressing plate 42 is pressed down to contact the upper end of the carton board. When the pressure is sufficient, the force acting on the force surface of the pressure sensor Q2 is large, and the voltage signal output by its 3rd pin is relatively high. In this way, the voltage signal output by the 3rd pin of the pressure sensor Q2 is divided by the resistors R1 and R2 and enters the base of the transistor VT, which is higher than 0.7V. The transistor VT will turn on the collector to output a low level and enter the base of the transistor VT. The transistor VT will turn on the collector and output a low level and enter the negative power input terminal of the transistor K. The relay K will be energized to attract its control power input terminal and the normally closed contact terminal to open the circuit. Then, the 24V power supply will no longer continue to enter the negative and positive power input terminals of the electric push rod M through the two control power input terminals and the two normally closed contact terminals of the relay K. The electric push rod M will no longer be energized to push the pressing plate downward to complete the indentation operation on the carton board. After the creasing is completed, the staff member turns the power switch S1 handle to the left again, so that the electric push rod M1 will drive the pressing plate upward again. After it is in place, the power switch is turned off, and the folded carton board can be taken out from left to right, and the creasing operation can be carried out on other parts of the carton board. Through the above, the new model can accurately control the downward distance of the pressing plate and the creasing force under the joint action of the control circuit and pressure sensor, ensuring the effective creasing of the corresponding position of the carton board while preventing the carton board from being damaged due to excessive creasing force. This new model brings convenience to the staff and correspondingly improves work efficiency.
