Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, specifically a carrot packaging machine. Background Technology

[0002] Currently, pillow-type packaging machines are commonly used for packaging carrots. The working principle of a pillow-type packaging machine is as follows: the power mechanism drives the paper film pressure roller to rotate and convey the paper film. The paper film is conveyed on the surface of the packaging machine and forms a "U-shaped" structure that facilitates the placement of fruits and vegetables. The conveyor belt automatically conveys the fruits and vegetables to the packaging position and packages them in the paper film. Then, the two sides of the paper film are heated and pressed into shape, and then sent to the horizontal sealing cutter for heat sealing and cutting. When using a pillow-type packaging machine, it usually needs to be used in conjunction with a feeding mechanism so that the carrots to be packaged are conveyed onto the conveyor belt on the pillow-type packaging machine through the feeding mechanism. After the pillow-type packaging machine packages the carrots, the packaged carrots are output as finished products by the conveyor belt.

[0003] Existing utility model application No. 202421505889.4 discloses a pillow-type packaging machine. The machine body is further equipped with a conveying system, a packaging system, a film feeding system, a material feeding system, and an adjustment system connecting a drive system and a control system. The conveying system includes a first conveyor belt and a second conveyor belt. The packaging system includes a processing chamber and a slitting module disposed within the processing chamber. The film feeding system includes a first feeding shaft, a second feeding shaft, and a guide roller assembly. The material feeding system includes a material feeding belt and a fixing frame. The adjustment system includes a lifting mechanism, a cleaning mechanism, and a moving mechanism. A start switch activates the cleaning unit to clean the surface of the material feeding belt. After cleaning, the belt is quickly dried by a drying module. The drying module uses heated air and a fan to blow away residual water droplets from the surface of the material feeding belt. This structure reduces labor costs and increases cleaning efficiency.

[0004] However, the aforementioned pillow packaging machine cannot adjust the height of the machine body according to the height of different feeding mechanisms, resulting in low applicability of the device. Utility Model Content

[0005] In order to solve the problem that some existing pillow-type packaging machines for carrots cannot adjust the height of the machine body according to the height of different feeding mechanisms, resulting in low applicability of the device, the purpose of this utility model is to provide a carrot packaging machine.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a carrot packaging machine, including a mounting frame, a lifting plate slidably mounted inside the mounting frame, a lifting assembly mounted on the mounting frame, the lifting assembly including two symmetrically distributed threaded rods, the two threaded rods being rotatably mounted in both ends of the mounting frame, a worm gear being fixedly mounted at the bottom end of each of the two threaded rods, a drive shaft being rotatably mounted at the bottom end of the mounting frame, two symmetrically distributed worms being fixedly mounted on the drive shaft, and the worms meshing with the corresponding worm gears, a drive motor being fixedly mounted at one end of the mounting frame, and the output end of the drive motor being fixedly connected to one end of the drive shaft, and a mounting assembly being mounted on the lifting plate.

[0007] Preferably, the mounting assembly includes two mirror-distributed slide grooves, which are slidably mounted on a lifting plate. A first bidirectional lead screw is rotatably mounted inside the lifting plate, and the first bidirectional lead screw is threaded into the bottom end of the corresponding slide groove. A drive shaft is rotatably mounted inside the lifting plate, and a second bevel gear is fixedly mounted at one end of the drive shaft. A first bevel gear is fixedly mounted in the middle of the first bidirectional lead screw, and the first bevel gear meshes with the second bevel gear. Two symmetrically distributed mounting feet are slidably mounted in each of the two slide grooves, and a second bidirectional lead screw is rotatably mounted in each of the two slide grooves, with the second bidirectional lead screw threaded into the corresponding two mounting feet.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] 1. In this utility model, the pillow packaging machine for packaging carrots can be fixedly installed on the lifting plate by bolts. By setting the lifting component, the lifting plate can be driven to slide and lift within the mounting frame according to the height of the discharge end of the feeding mechanism for conveying carrots. The lifting plate drives the pillow packaging machine to lift and adjust, so that the height of the conveyor belt on the pillow packaging machine is consistent with the height of the discharge end of the feeding mechanism, which facilitates the conveying and packaging of carrots.

[0010] 2. In this utility model, by setting the installation components, the installation feet can be adjusted according to the size of different pillow packaging machines, so that the installation feet correspond to the installation ears at the four corners of the bottom of the pillow packaging machine, which is convenient for installing pillow packaging machines of different sizes.
