Description

Technical Field

[0001] The invention relates to the technical field of wrapping packaging facilities, in particular to a wrapping packaging machine. Background Art

[0002] In the process of transplanting some small trees, a wrapping machine is usually used to wrap a circle of film around the small trees to reduce water evaporation and improve the survival rate of the trees. However, the existing wrapping machine can only perform the film wrapping operation when working, and its operation is single. As a result, when the temperature of the external environment is too high, the evaporation of water cannot be avoided by relying solely on the wrapped film, that is, the ability to reduce water evaporation is poor, resulting in a reduced survival rate of the trees.

[0003] According to application number 201721286985.4, a wrapping machine includes a frame, on which a pipe mounting position is provided. The pipe mounting position is provided at both ends of the frame, and is respectively composed of two close and fixed pulleys. The pulley includes a driving wheel and a driven wheel. The driving wheel is connected to a power source through a belt. When the pipe is placed in the pipe mounting position, the driving wheel can drive the pipe to rotate circumferentially. A controller for controlling the operation of the power source is provided on one side of the frame.

[0004] The device drives the pipe to rotate circumferentially through the driving wheel. The operator only needs to wrap the plastic film around one end of the pipe and then move it along the axial direction of the pipe. The rotating pipe will be wrapped with the plastic film. Compared with manual wrapping, it is faster and more convenient, improves production efficiency and saves labor costs. However, the two sets of supporting components set in the device cannot be moved, so the product cannot be completely wrapped and packaged. Summary of the invention

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. The wrapping packaging machine places the tree in the rotating drum through the winding assembly, and the two ends of the tree are placed on the placement plate. Then the motor is started to rotate the first pulley, and the first pulley rotates the second pulley and the third pulley through the cooperation of the belt, so that the first gear and the second gear rotate.

[0017] 2. The wrapping packaging machine, through the setting of the moving component, the rotation of the second gear will drive the third gear to rotate, so that the screw will rotate, the rotation of the screw will drive the two screw blocks to move to the right, thereby driving the two placement plates to move to the right, thereby driving the trees on the top of the placement plates to move to the right, so when the motor is started, it will wrap the trees and move the trees to the right at the same time, so that the surface of the trees can be wrapped more thoroughly.

[0018] 3. The wrapping packaging machine places the tree on the placement board through the provided fixing mechanism, and then starts the motor to rotate the screw. The rotation of the screw will cause the two placement boards to drive the tree to move to the right, and at the same time drive the L block to move to the right, so that the bottom end of the L block slides on the inclined top of the inclined plane block. When the bottom end of the L block leaves the inclined top of the inclined plane block, the clamping block will move downward through the elastic force of the first spring, so that the clamping block and the placement board clamp and fix the tree, so that the tree is more stable during wrapping and the tree will not shake. After the tree is wrapped, the film is cut, and then the motor is used to rotate the screw in the opposite direction, so that the two placement boards drive the tree to move to the left, thereby moving the L block to the left, and the bottom end of the L block will slide on the inclined top of the inclined plane block, so that the L block moves upward, thereby driving the clamping block to move upward, increasing the distance between the clamping block and the placement board, and facilitating the removal of the tree from the placement board.

[0019] 4. The wrapping packaging machine, through the provided limiting mechanism, sleeves the film roll on the surface of the rotating drum, then slides the second disc into the surface of the rotating drum, then pulls the connecting block to the right to make the connecting block move away from the inside of the rotating drum, and at the same time drives the second guide rod and the limiting plate to move to the right, thereby squeezing the second spring, then slides the L limiting block into the groove on the front side of the connecting block, and then releases the connecting block. At this time, the L limiting block will move to the left through the elastic force of the second spring, so that the protruding end of the L limiting block fits with the right side of the second disc, so that the second disc and the first disc limit the film roll on the surface of the rotating drum, so that the film roll will not fall off the rotating drum when wrapping the tree.

At this time, the L limiting block 59 will move to the left through the elastic force of the second spring 57, so that the protruding end of the L limiting block 59 is in contact with the right side of the second disc 53, so that the second disc 53 and the first disc 52 limit the film roll on the surface of the rotating cylinder 51, so that the film roll will not fall off the rotating cylinder 51 when it is wrapped around the tree.
