Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of medical packaging production equipment, and particularly relates to a transparent paper wrapping machine. BACKGROUND

[0002] After a series of packaging procedures such as aluminum-plastic machines, pillow packaging machines, boxing machines, wrapping machines and boxing machines, the medicine is completed. Because the transparent paper wrapping machine often appears the following situations in the production process:

[0003] The first situation is that the medicine boxes in the conveying process are arranged loosely on the medicine conveying path. When the inside push box cylinder pushes the medicine packaging box to the buffer plate, there will be less than 10 boxes. The most edge small box will also appear to be tilted during the pushing process. When the plastic sealing is performed, the phenomenon of lacking 1-2 medicine packaging boxes will appear, and even the tilted small box will also be plastic sealed inside.

[0004] The second situation is that the proximity switch on the guide plate occasionally appears position change due to continuous production. When the proximity switch does not sense the medicine packaging box pushed to the buffer plate by the inside push box cylinder, the outside push box cylinder will not push the medicine small box on the buffer plate into the wrapping machine. However, the medicine packaging boxes on the medicine conveying path will be pushed to the buffer plate by the inside push box cylinder after reaching a certain number, so as to collide with the medicine packaging boxes that are not pushed away on the buffer plate. Therefore, it is necessary to stop the vehicle to handle the extrusion failure.

[0005] The above two situations not only affect the overall production capacity of the equipment, but also cause waste of production packaging materials. In addition, frequent stopping of the vehicle has unpredictable phenomena on the overall equipment. SUMMARY

[0006] In order to solve the above problems and overcome the shortcomings of the prior art, the present application provides a transparent paper wrapping machine to solve the two failures of the wrapping machine proposed in the background art, reduce unnecessary production stops and waste of production packaging materials in the production process, and improve the overall production capacity of the equipment.

[0007] The specific technical scheme for solving the above technical problems is as follows: a transparent paper wrapping machine, comprising a machine body, a proximity switch, a medicine conveying path, a buffer plate, a guide plate, a warning light and a control panel, characterized in that: the machine body is provided with an inside brush and an outside brush parallel to the medicine conveying path on one side close to the medicine conveying path. The buffer plate is vertically fixed with a guide plate, the guide plate has a rectangular hole, and the guide plate is provided with a fixed support through bolts. The proximity switch is connected to the guide plate through the fixed support, and the fixed support is provided with a metal sheet with an arc. The metal sheet is close to the front end of the proximity switch, and the arc top end of the metal sheet penetrates through the rectangular hole of the guide plate. When the inside push box cylinder pushes the medicine packaging box to the buffer plate, the small box will extrude the metal sheet, and the metal sheet will contact the probe of the proximity switch.

[0008] The inner side brush is less than the height of one medicine package box above the medicine delivery channel, and the outer side brush is less than the height of one medicine package box above the buffer plate, the brush comprises a brush fixing plate and a brush fixing frame, the brush fixing frame is fixedly connected with the machine body, the brush fixing plate and the brush fixing frame are connected through bolts, and springs are sleeved on the bolts.

[0009] A push box air cylinder parallel to the medicine delivery channel is installed in the horizontal direction of the buffer plate, one end of a push rod is connected with an electromagnetic valve, and the push rod and the electromagnetic valve are connected by the air cylinder.

[0010] A push box air cylinder parallel to the medicine delivery channel is installed in the horizontal direction of the buffer plate, one end of a push rod is connected with an electromagnetic valve, and the push rod and the electromagnetic valve are connected by the air cylinder.

[0011] The beneficial effects of the present application are as follows: after installing the inner side brush and the outer side brush less than the height of one medicine package box above the medicine delivery channel and the buffer plate respectively, when the medicine package box passes through the delivery channel to the bottom of the brush, the bristles on the brush can gently press the medicine package box, so that the small boxes are not too loose, and the process of pushing to the buffer plate will not be tilted, solving the phenomenon that 1-2 medicine package boxes are missing or the tilted small boxes are also sealed in the process of sealing.

[0012] The brush fixing plate and the brush fixing frame are connected through bolts, and the nuts connecting the brush fixing plate and the brush fixing frame in continuous production are self-loosened. When the nut is loosened, the position of the brush fixing plate will be lowered, the fixing pressure of the small box will be increased, and the medicine small boxes pushed by the inner side push box air cylinder to the buffer plate will exceed 10 boxes. At this time, the excess small boxes will hit the corner of the outer side baffle of the medicine delivery channel, causing extrusion. The spring is sleeved on the bolt, and the nut is replaced by two nuts. Because the spring on the bolt plays a buffering role in the stress of the brush fixing plate, the stress of the brush fixing plate due to continuous production is reduced, and two nuts are used for reinforcement, so that the position of the brush fixing plate will not change due to continuous production. Therefore, the brush fixing plate can gently press the medicine package box, solving the problem that the small box will hit the corner of the outer side baffle of the medicine delivery channel due to the loosening of the position of the brush fixing plate.

[0013] The front end of the proximity switch on the guide plate is provided with a metal sheet with an arc, which increases the sensing sensitivity of the proximity switch and avoids the collision of the inner and outer medicine boxes due to the insensitive sensing of the proximity switch on the guide plate.
