Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical packaging technology, and in particular to a medicine box leveling mechanism. Background Technology

[0002] Currently, medicines are typically packaged in multiple boxes, stacked together for overall packaging. However, after the medicines are boxed, the contents can push up the top or bottom of the box, causing it to arch. This makes it difficult to stack the medicines flat and tightly during subsequent sealing or packaging, affecting the overall packaging.

[0003] Patent CN210083659U discloses a leveling and conveying device for medicine boxes before bundling. It includes a circulating conveyor belt with crossbeams mounted above both ends. Elastic pressure strips are installed between the two ends of the crossbeams. A long strip-shaped pressure plate assembly along the conveying direction is installed in the middle of the crossbeams. The pressure plate assembly includes a fixing plate, one end of which is fixedly mounted on the crossbeam, and the other end is welded to a pressure plate integral with it. A brush plate is fixedly mounted at the bottom of the pressure plate, secured by clamps on both sides of the pressure plate. The bottom surface of the brush plate is covered with bristles. There are no baffles on either side of the circulating conveyor belt corresponding to the pressure plate's position, and a push rod facing the circulating conveyor belt is installed on one side. A liftable receiving plate is installed on the other side of the circulating conveyor belt. This device uses the elastic pressure strips above the circulating conveyor belt and the pressure plate assembly to press and level the medicine boxes conveyed on the circulating conveyor belt. However, it cannot contact the entire top surface of the medicine boxes, thus failing to achieve the effect of leveling the entire top surface of the medicine boxes. Utility Model Content

[0004] This invention addresses the problem that existing medicine box leveling devices cannot achieve the effect of leveling the entire top surface of the medicine box, and provides a medicine box leveling mechanism with a simple structure that can simultaneously level the entire top and bottom surfaces of the medicine box.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A medicine box leveling mechanism of the present invention includes side plates arranged opposite to each other on both sides of a conveyor belt, a leveling roller between the side plates, the leveling roller being located above the conveyor belt, the gap between the leveling roller and the conveyor belt forming a leveling channel, a front pressure plate and a rear pressure plate arranged on the front and rear sides of the leveling roller along the running direction of the conveyor belt, the front pressure plate and the rear pressure plate being located above the conveyor belt, the gap between the front pressure plate, the rear pressure plate and the conveyor belt forming a medicine box channel, and opposite guide plates arranged on the left and right sides of the front pressure plate, the space enclosed by the guide plates and the conveyor belt forming a guide channel. In this invention, the side plates are fixed to the frame, and the conveyor belt passes between the side plates. The medicine box moves forward with the conveyor belt, enters the medicine box channel after passing through the guide channel, and when the medicine box passes through the medicine box channel, the top and bottom surfaces of the medicine box are leveled by the action of the leveling roller and the conveyor belt, respectively. The guide plate plays a guiding and positioning role to ensure that the medicine box can completely pass through the leveling roller. The height of the leveling channel is adapted to the height of the medicine box. The length of the leveling roller should be greater than the width of the medicine box, and the width of the conveyor belt should be greater than the width of the medicine box.

[0006] Preferably, a horizontal plate is fixed to the upper end of the side plate, and a U-shaped bracket is provided below the horizontal plate. The leveling roller is rotatably mounted inside the U-shaped bracket. A bearing seat is provided on the horizontal plate, and a rotating rod is provided inside the bearing seat. The rotating rod passes through the horizontal plate and the U-shaped bracket, and its lower end is threadedly connected to the U-shaped bracket. The heights of the front and rear pressure plates are adjustable. By rotating the rotating rod, the U-shaped bracket can be raised and lowered, making height adjustment convenient. Simultaneously, the heights of the front and rear pressure plates are adjustable, thereby adjusting the height of the medicine box channel. This allows the present invention to be applicable to medicine boxes of different heights, providing greater flexibility in use.

[0007] Preferably, lifting guide rods are provided on both sides of the rotating rod. The lifting guide rods pass through the horizontal plate and slide in cooperation with the horizontal plate. The lower end of the lifting guide rod is fixedly connected to the U-shaped bracket.

[0008] Preferably, the U-shaped bracket is provided with a front fixing plate, and the front pressure plate is fixed on the front fixing plate. The free end of the front pressure plate is curved upwards into an arc shape. The front fixing plate may have an adjustment elongated hole. The front fixing plate can be fastened to the U-shaped bracket by a connecting screw passing through the adjustment elongated hole. Loosening the connecting screw allows the front fixing plate to move up and down, thereby adjusting the height of the front pressure plate, which is convenient.

[0009] Preferably, a fixed guide rod is provided between the side plates. The fixed guide rod passes through the guide plate, and the guide plate and the fixed guide rod are slidably engaged. The guide plate and the fixed guide rod are fastened together by a locking device. The locking device can be a conventional locking device such as a set screw or a handle locking screw. The guide plate and the fixed guide rod are fastened together by the locking device, allowing the guide plate to move along the fixed guide rod, thereby adjusting the width between the guide plates. This allows the present invention to be applicable to medicine boxes of different widths.

[0010] Preferably, the side plate is provided with a rear fixing plate, the rear pressure plate is fixed on the rear fixing plate, and the free end of the rear pressure plate is curved upward in an arc shape.

[0011] Therefore, this utility model has the following beneficial effects: when the medicine box passes through the medicine box channel, the top and bottom surfaces of the medicine box can be leveled by the leveling roller and the conveyor belt respectively, resulting in a good leveling effect. This ensures that the medicine boxes can be stacked flat and tightly during subsequent overall packaging, thus guaranteeing packaging quality. Attached Figure Description
