Description

Technical Field

[0001] The utility model relates to packaging equipment, in particular to a blister packaging machine which is convenient for changing rolls. Background Art

[0002] Blister packaging machine is a common packaging equipment. The substrate of blister packaging needs to be unwound by a film unwinding mechanism. When the unwound film material is about to run out, the film material needs to be replaced. The traditional film unwinding mechanism generally only has a fixed single unwinding seat. After the film material is used up, the unwinding shaft needs to be removed and replaced with a new unwinding shaft with film material. The defect of this unwinding mechanism is that the unwinding seat is fixed. In order to ensure that there is no friction at the bottom of the film material during the unwinding process, the unwinding seat needs to be set at a certain height. Therefore, when replacing a new film roll, the film roll needs to be manually lifted to the unwinding seat, and when replacing a new film roll, the new film roll needs to be manually taken from a specific storage position and then replaced. The labor intensity of the workers is very high, the replacement efficiency is not high, and the user experience is not good. Utility Model Content

[0003] In view of the shortcomings of the background technology, the technical problem to be solved by the utility model is to provide a blister packaging machine which is convenient for changing rolls and is used to solve the above problems.

[0004] To this end, the utility model is implemented by adopting the following scheme:

[0005] A blister packaging machine that is convenient for roll changing includes a film unwinding mechanism, a feeding mechanism, a blister forming mechanism and a heat sealing mechanism, and is characterized in that: the film unwinding mechanism includes an unwinding frame, the unwinding frame has a left frame plate and a right frame plate, and the left and right frame plates are both provided with inclined sections, and the inclined sections can be used for the unwinding shaft of the film roll waiting for roll changing to abut against, and unwinding seats are movably arranged on the left and right unwinding frames, and the unwinding seats are connected to a movable driving component, and the movable driving component can drive the unwinding seat to move obliquely up and down along the inclined section.

[0006] The mobile driving component includes a driving motor, the output end of the driving motor is connected to the driving wheel, the driving wheel is passed around a transmission belt, and the transmission belt is passed around a first driven wheel and a second driven wheel, so that the part of the transmission belt located between the first and second driven wheels forms an inclined belt section with the same inclination angle as the inclined surface section, and the unwinding seat is connected to the inclined belt section.

[0007] A warp winding roller group and a deviation correction component are arranged above the unwinding seat.

[0008] An obliquely arranged collision section is provided at one end of the unwinding seat and can squeeze and drive the unwinding shaft of the film roll waiting for roll change to move.

[0009] The blister packaging machine of the above technical solution is convenient for roll changing. By additionally adding a mobile driving component, the unwinding seat is driven to move obliquely, so that the unwinding shaft of the film material will drive the film material to be obliquely lifted a certain distance after rolling into the unwinding seat, to ensure that no friction occurs when the bottom of the film material is unrolled. At the same time, the oblique lifting method according to the unwinding situation prevents the film material from colliding with other internal components, and can better free up extra space for the positioning and placement of the new film material roll waiting to be replaced. The film material can be easily replaced, which effectively reduces the labor intensity of the workers and improves the efficiency and quality of roll changing. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] As shown in the figure, the blister packaging machine for easy roll change disclosed by the utility model comprises a film unwinding mechanism, a feeding mechanism, a blister forming mechanism and a heat-sealing mechanism, wherein the feeding mechanism, the blister forming mechanism and the heat-sealing mechanism all belong to the prior art and are common structures on the market, so they are not described in detail, and the feeding mechanism, the blister forming mechanism and the heat-sealing mechanism are all located in the outer frame shell, the film unwinding mechanism comprises an unwinding frame, the unwinding frame has a left frame plate 14 and a right frame plate 1, both the left and right frame plates have an inclined surface section 12, the inclined surface section 12 can be used for the unwinding shaft of the film roll waiting for roll change to abut against, , an unwinding seat 2 is movably arranged on the right unwinding frame, and the unwinding seat 2 is connected to a mobile driving assembly, which can drive the unwinding seat 2 to move up and down along the inclined surface section 12 in an oblique direction. In this embodiment, the mobile driving assembly includes a driving motor 6, and the output end of the driving motor 6 is connected to the driving wheel 7. The driving wheel 7 is passed through a transmission belt 8, and the transmission belt 8 is passed through the first driven wheel 9 and the second driven wheel 13, so that the portion of the transmission belt 8 between the first and second driven wheels forms an oblique belt section 11 with the same inclination angle as the inclined surface section 12, and the unwinding seat 2 is connected to the oblique belt section 11. A winding roller group 3 and a deviation correction assembly 4 are arranged above the corresponding unwinding seat 2 to facilitate the directional transmission and deviation correction of the film material. At one end of the unwinding seat 2, there is an obliquely arranged collision section 15 that can squeeze and drive the unwinding shaft of the film roll waiting for roll change to move.

[0014] The working principle of the utility model is as follows: the unwinding shaft wound with the film material rolls into the unwinding seat 2, and the inclined belt section 11 of the transmission belt 8 drives the unwinding seat 2 to be lifted, and the unwinding shaft of the new film material roll waiting for reel replacement abuts against the inclined surface section 12 to realize positioning and waiting. When the unwinding shaft on the unwinding seat 2 is unwound, the empty unwinding shaft is taken away from the unwinding seat 2, and the unwinding seat 2 is controlled to descend, and the collision section 15 on the unwinding seat 2 first contacts and squeezes the unwinding shaft to move, making room for the unwinding seat 2 to continue to descend to the material receiving position, and then gently pushes the film material, so that the unwinding shaft can be stuck in the unwinding seat to realize positioning and placement, and then the unwinding seat 2 is controlled to drive the new unwinding shaft to rise to a suitable height for unwinding, and the unwinding shaft of the next roll of waiting film material abuts against the inclined surface section 12 for positioning and waiting, and this cycle realizes the rapid reel changing operation of the film material.

[0015] The structure of the utility model, by additionally adding a mobile driving component to drive the unwinding seat to move obliquely, enables the unwinding shaft of the film material to drive the film material to be obliquely lifted a certain distance after rolling into the unwinding seat, to ensure that no friction occurs when the bottom of the film material is unwound, and at the same time, the oblique lifting method according to the unwinding situation prevents the film material from colliding with other internal components, and can better free up excess space for positioning and placing the new film roll waiting to be replaced, so that the film material can be easily replaced, effectively reducing the labor intensity of workers and improving the efficiency and quality of roll replacement.
