Description

Technical Field

[0001] The utility model relates to a box-opening auxiliary structure of a cartoning machine, and relates to the technical field of medicine packaging equipment, in particular to a box-opening auxiliary structure of a box-opening machine for oral liquid packaging boxes. Background Art

[0002] At present, the cartoning machine equipment used on site uses two adsorption devices to adsorb the front and sides of the small box, and then rotates the side suction cup to open the small box. In the actual production process, the cartoning machine needs to produce packaging for oral liquid bottled products of different specifications. Since the small boxes required for different specifications of products are of different sizes, there is no scale for adjusting the position of the suction cup, and each test is relied on to check whether the position is adjusted correctly. The adjustment cycle is relatively long, and the adsorption stability of the suction cup is not very stable, and there is often a phenomenon of falling off the disc. The above phenomenon causes the opening and closing rate of the small box to be around 70%, resulting in strict requirements for the small box by the cartoning machine. At the same time, the continuous operation time of the cartoning machine is seriously shortened, resulting in low daily output.

[0003] In view of the problems existing in the above-mentioned prior art, it is very necessary to study and design a new type of carton opening auxiliary structure for a cartoning machine so as to overcome the problems existing in the prior art. Summary of the invention

[0004] According to the technical problems of the above-mentioned prior art, such as the long adjustment cycle, unstable suction of the suction cup leading to the disc falling off, low opening and closing rate leading to short continuous operation time of the equipment, and low output, a cartoning machine opening auxiliary structure is provided. The utility model mainly utilizes the elastic structure of the auxiliary structure to overcut and rub the small box to open the small box, thereby achieving the effects of improving the opening rate, reducing the machine adjustment time, and reducing the small box machine damage rate.

[0005] The technical means adopted by the utility model are as follows:

[0006] A carton opening auxiliary structure for a cartoning machine, comprising a circular carton opening device;

[0007] Furthermore, an auxiliary structure is fixedly arranged on one side of the box opening device;

[0008] Furthermore, the auxiliary structure contacts the small box on the box opening device to open the small box from a folded state.

[0009] Furthermore, the main body of the auxiliary structure is an S-shaped structure made of an elastic metal sheet, which consists of an S-shaped upper end and an S-shaped lower end at the bottom.

[0010] Furthermore, the lower end of the S-shape is a horizontal balance rod structure, which is used to fix the auxiliary structure to the equipment on one side of the box opening device.

[0011] Furthermore, the upper end of the S-shape is an arc-shaped structure turned outward;

[0012] Furthermore, the outer end of the upper end of the S-shaped part is in contact with the outer side surface of the small box, and the small box is expanded from the folded state.

[0013] Furthermore, the circular motion of the upper end of the S-shaped part and the small box achieves a small amount of overcutting, reducing resistance and avoiding damage to the small box.

[0014] Compared with the prior art, the present utility model has the following advantages:

[0015] 1. The box-opening auxiliary structure provided by the present utility model increases the original box-opening rate from 70% to 90%.

[0016] 2. The box-opening auxiliary structure provided by the present utility model shortens the machine adjustment time by more than 60 minutes.

[0017] 3. The box-opening auxiliary structure provided by the present utility model can quickly adjust the machine adjustment position of the box-opening part of the small box, shortening the running-in time.

[0018] 4. The box-opening auxiliary structure provided by the present utility model reduces the damage rate of the small box and solves the cost of the outer packaging material.

[0019] In summary, the technical solution of the present utility model solves the problems in the prior art, such as a relatively long adjustment period; the phenomenon of tray detachment caused by unstable suction of the suction cup; a low opening and closing rate resulting in a short continuous operation time of the equipment; and low output.
