Description

Technical Field

[0001] The utility model relates to a sealing and cutting mechanism, in particular to a sealing and cutting mechanism of PET composite packaging material forming equipment, belonging to the technical field of material forming equipment. Background Art

[0002] In the prior art, for example, the utility model with application number 202120784456.7 discloses a sealing and cutting mechanism for a PET composite packaging material forming device. In order to solve the problem that the packaging and cutting of composite packaging materials are mostly carried out in steps, that is, the composite packaging material is first packaged by a packaging machine, and then cut by a cutting mechanism to form medicine plates of the same specifications. This process is carried out in steps, which reduces the work efficiency. The upper cutting block and the lower cutting block move relative to each other to package the composite hard sheet, and each cutting block is provided with a cutting blade. The composite hard sheet passes through the gap between the upper cutting block and the lower cutting block. The upper cutting block and the lower cutting block and the corresponding cutting blade move relative to each other to seal and cut the composite hard sheet to form medicine plates of the same specifications. In this process, the packaging and cutting of the composite hard sheet are carried out simultaneously, thereby improving the work efficiency.

[0003] Similar to the above application, there are still some shortcomings:

[0004] During the sealing and cutting process, two sets of cylinders need to be coordinated to control the simultaneous movement of the cutting blade and the sealing block to complete the sealing and cutting operation. The synchronous control of the cylinders is relatively inconvenient. In addition, the slicing knife moves horizontally and cannot be separated quickly after the sealing and cutting is completed. Therefore, the product needs to pause for a certain period of time during sealing and cutting. An intermittent feeding method is used to reduce the sealing and cutting speed.

[0005] Therefore, a sealing and cutting mechanism of a PET composite packaging material forming device is designed to optimize the above-mentioned problems. Utility Model Content

[0006] The main purpose of the present utility model is to provide a sealing and cutting mechanism for a PET composite packaging material forming device. By installing the cutting knife on the outside of two groups of gears, the two groups of gears are meshed with each other, and a group of motors are used to control the synchronous rotation of the two groups of gears, making the synchronous control of the cutting knife more convenient. On both sides of the cutting knife, cutting and sealing plates are symmetrically and slidably arranged. Before the two groups of cutting knives perform sealing and cutting operations, the cutting and sealing plates first contact the product, move down simultaneously with the product, and complete the sealing plate operation before cutting. After sealing and cutting, the cutting knife and the cutting and sealing plates can be quickly separated, which will not affect the continuous conveying of the product and improves the sealing and cutting speed during use. By annularly and arrayedly opening slots on the inner side of the mounting plate, and arranging a positioning component composed of a mounting groove, a pulling block, a second spring, and an inserting block on the outside of a group of mounting plates, during the sealing and cutting process, the number of installed cutting knives can be controlled according to the sealing and cutting length, and at the same time, the plug-in method is used for installation, which is more convenient for disassembly and assembly and has higher practicability.

[0025] The overall working principle is: the fixed plate 1 is horizontally installed on the molding equipment, and the PET composite hard sheet and the aluminum foil are preheated and bonded to form a medicine plate, which passes vertically between the two sets of mounting rods 5, and then the motor 3 is started to drive the two sets of gears 2 to rotate. The two sets of gears 2 rotate in opposite directions and drive the cutter 8 to rotate at the same time. During the rotation of the cutter 8, the cutting and sealing plate 9 on the outside of the cutter 8 first contacts the medicine plate and moves down with it, and during the downward movement, the medicine plate is pressed and sealed. After sealing and pressing, the two cutters 8 are aligned to cut the medicine plate, and after sealing and cutting, the cutters 8 are quickly separated. At this time, the cutting and sealing plate 9 is still in contact with the medicine plate and moves down together. As the distance between the cutters 8 increases, the medicine plate automatically falls down, and the sealing and cutting is completed.

[0026] In this embodiment, the fixing plate 1 is in the shape of an arch bridge, and mounting holes are formed at both ends of the fixing plate 1 .

[0027] Partial working principle: During the installation process, bolts are passed through the installation holes to horizontally fix the fixing plate 1 on the equipment.

[0028] In this embodiment, a U-shaped frame 4 is fixed between the two ends of the outer side of the fixing plate 1, and the end of the mounting rod 5 is rotatably connected to the U-shaped frame 4.

[0029] Partial working principle: The use of the yoke 4 can form protection on the outside of the mechanism to ensure the stable operation of the mechanism.

[0030] In this embodiment, eight groups of slots 7 are provided on the side of the mounting plate 6 , and the angle between adjacent slots 7 and the center of the mounting plate 6 is 45°.

[0031] Partial working principle: by opening multiple groups of slots 7 on the installation disk 6, multiple groups of cutters 8 can be installed between the installation disks 6 according to usage requirements, which is more practical.

[0032] In this embodiment, horizontal plates 11 are vertically fixed on both sides of the cutter 8 along the length direction, a first spring 12 is provided between the top of the horizontal plate 11 and the cutting and sealing plate 9, and a sliding rod 13 is vertically fixed to the bottom end of the cutting and sealing plate 9, and the sliding rod 13 passes through the first spring 12 and the inside of the horizontal plate 11.

[0033] Partial working principle: During the sealing process, the sealing plate 9 first contacts the medicine plate, and as the gear 2 rotates, the sealing plate 9 is pressed down to squeeze the first spring 12 so that the cutters 8 contact each other for cutting. After the cutters 8 separate from each other, the first spring 12 can be used to control the reset of the sealing plate 9 for secondary sealing.

[0034] In this embodiment, the positioning assembly 10 includes a mounting groove 14, a pull block 15, a second spring 16, an insert block 17 and a socket 18.

The end of the cutter 8 is opened with a socket 18 that cooperates with the insert block 17.

[0035] Partial working principle: After the cutter 8 is inserted into the slot 7, the plug block 17 is inserted into the socket 18 to fix the position of the cutter 8. When the cutter 8 is replaced or repaired, the pull block 15 is buckled out, the plug block 17 is pulled and removed from the socket 18 to release the positioning state of the cutter 8.

[0036] In this embodiment, the shape of the insert block 17 is a right-angled trapezoid, and the inclined surface of the insert block 17 is located inside the slot 7 and faces the outside of the mounting plate 6 .

[0037] Partial working principle: When the cutter 8 is inserted, it will first contact the bevel of the plug block 17, squeezing the plug block 17 into the inside of the installation groove 14. After the plug block 17 is aligned with the socket 18, the insertion of the plug block 17 is automatically controlled by the elastic force of the second spring 16, making positioning more convenient.
