Description

Technical Field

[0001] The utility model relates to the field of packaging, in particular to an automatic folding device for a medicine packaging box. Background Art

[0002] In a pharmaceutical factory, turning a piece of paper into a medicine box generally includes six steps: design, printing, cutting, folding, glue spraying, and inspection, namely: first, design the structure and size of the medicine box according to the characteristics of the medicine and packaging requirements; then print the designed medicine box pattern on the paper; then cut the printed paper into the corresponding medicine box size according to the design size of the medicine box; then put the cut paper into the folding machine and fold it according to the preset crease line to form the basic shape of the medicine box; next, use the glue spraying machine to spray glue on the parts of the medicine box that need to be glued to glue the parts of the medicine box together; finally, the finished medicine box is inspected for appearance, measured for size and other quality inspections to ensure that the medicine box meets the standards and requirements. Most traditional folding processes rely on manual operation. Workers need to manually fold the paper in a specified manner. Such operation is inefficient and the clarity and accuracy of the creases cannot be guaranteed during folding, which affects the appearance and quality of the medicine box. At the same time, the traditional folding process can only achieve a fixed folding sequence and cannot flexibly adapt to the folding requirements of different medicine box designs, resulting in difficulty in adjusting the production line and low efficiency. Traditional glue spraying mechanisms are usually fixed in one position and cannot accurately spray glue according to the structure and requirements of different medicine boxes, so some parts may not be fully coated with glue, resulting in uneven glue spraying, affecting the sealing and stability of the medicine box. In addition, the current glue spraying process often requires multiple steps and manual operations, including preparation before glue spraying and cleaning after glue spraying, which increases the process complexity and production time.

[0003] In summary, the current folding and glue spraying process has many disadvantages such as low manual operation efficiency, single folding sequence, inaccurate glue spraying position, uneven glue spraying, large space occupation, etc., which limits the efficiency and quality of medicine box production and increases production costs. Therefore, an automated device integrating folding and glue spraying is needed to overcome these problems, reduce enterprise production costs, and improve production efficiency and packaging quality.

DETAILED DESCRIPTION

[0022] The embodiments of the present invention will be described in detail below in conjunction with examples, but those skilled in the art will understand that the following examples are only used to illustrate the present invention and should not be construed as limiting the scope of the present invention.

[0023] Example 1

[0024] An automatic folding device for a medicine packaging box, as shown in the accompanying drawings, includes a base 8, a lead screw 1 is passed through the top of the base 8, a working arm 4 is connected to the bottom of the lead screw 1, a pressing plate 12 is connected to the bottom of the working arm 4, a control valve 20 is installed on the back of the pressing plate 12, a glue spray nozzle 13 is installed on the control valve 20, and the glue spray nozzle 13 is connected to a liquid storage tank 2 fixed on the base 8 through a hose 3; stepper motors 6 are installed at both ends of the lead screw 1, encoders 7 are installed on the stepper motor 6, and the stepper motor 6 equipped with the encoder 7 is placed outside the base 8; a working plate 16 is provided inside the base 8, and the working plate 16 is connected to folding plates 14 around, and a cylinder 11 is installed under each folding plate 14, and the bottom of the cylinder 11 is connected to the bracket 9; a suction cup 15 is embedded in the middle area of ​​the working plate 16, and the suction cup 15 is connected to the air pump 17 through an air pipe 19, and a timer 18 is installed at the connection between the air pipe 19 and the air pump 17.

[0025] The working arm 4 is equipped with a rotating motor 5 .

[0026] The folding plate 14 is composed of 12 plate members, and the infrared sensor 10 is installed on the folding plate 14 farthest from the working plate 16 .

[0027] The folding plate 14 can be folded upward by 90 degrees under the drive of the cylinder 11 .

[0028] Example 2

[0029] The working process of an automatic folding device for a medicine packaging box comprises the following steps:

[0030] Step 1: The paper is conveyed to the folding plate 14. The paper is completely attached to each folding plate 14, and the infrared sensor 10 is blocked. At this time, the air pump 17 generates negative pressure, and the suction cup 15 generates adsorption force on the bottom surface of the paper, so that the paper is firmly fixed on the working plate 16 and each folding plate 14. The timer 18 monitors the adsorption time.

[0031] Step 2: The stepper motor 6 drives the lead screw 1 to move, the encoder 7 provides real-time position feedback, the working arm 4 descends, the rotary motor 5 drives the working arm 4 to rotate, the pressing plate 12 moves to the top of the folding surface adjacent to the target folding surface, and the front of the pressing plate 12 falls on the intersection of the two folding surfaces, pressing the paper downward. At this time, the folding plate 14 corresponding to the target folding surface is driven by the cylinder 11 to fold upward 90 degrees, driving the paper on this side to fit with the pressing plate 12, resulting in a crease. The folding plate 14 is then driven by the cylinder 11 to return to the horizontal position, and the working arm 4 moves to the next folding position, and the folding process is repeated.

[0032] Step 3: When the folded side needs to be glued, the working arm 4 first moves vertically upward to leave the paper, then moves to the outside of the folded surface, descends and rotates, so that when the bottom of the pressing plate 12 fits the folding plate 14, the glue nozzle 13 is just aligned with the glue spraying position on the outside of the folded surface. The control valve 20 is opened, and the glue from the liquid storage tank 2 is pushed out by pressure, and sprayed out from the small hole of the glue nozzle 13 through the hose 3, forming a glue spray on the outside of the folded surface. Then the working arm 4 moves to the next place and repeats the folding or glue spraying process.

[0033] Step 4: After the paper has gone through the folding and gluing process, the air pump 17 stops generating negative pressure, and the suction cup 15 releases the suction force on the bottom surface of the paper, and then it is transported to other processes. Repeat Step 1, Step 2, and Step 3 to complete the automatic folding and gluing process of the next piece of paper.

[0034] The above embodiments are used to illustrate the present invention rather than to limit the present invention. Any modification and change made to the present invention within the spirit of the present invention and the protection scope of the claims shall fall within the protection scope of the present invention.
