Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vacuum feeding hoppers, in particular to a vacuum feeding hopper for PE materials. Background Art
[0002] A vacuum feeding machine, also known as a vacuum conveyor, is a dust-free and airtight pipeline conveying equipment that uses vacuum suction to convey granular and powdery materials. By utilizing the air pressure difference between the vacuum and the ambient space, it forms gas flow in the pipeline to drive the powdery materials to move, thus completing the conveying of powders. China has introduced advanced foreign vacuum technologies, continuously improved and refined them, and now they are widely used in various light and heavy industries such as chemical, pharmaceutical, food, metallurgy, building materials, and agriculture and sideline products.
[0003] According to a highly automated vacuum feeding machine disclosed in the patent with the patent number CN 218753656U, this device solves the problems that the existing vacuum feeding machine requires manual height adjustment operation, has a low degree of automation, and restricts its development and popularization through the functions of a synchronous belt, a motor, a connecting block, a controller, a support seat, a height recognition sensor, a pulley, a threaded rod, and a movable plate.
[0004] However, during the implementation of the technical solution of the above patent, it is not convenient to fix the suction pipe when the vacuum feeding machine sucks materials. When the existing vacuum feeding machine sucks materials, workers need to hold the suction pipe by hand to suck the materials in the feeding bucket into the suction pipe. This hand-held method requires workers to hold the suction pipe for a long time, making the workers relatively tired. Therefore, a highly automated vacuum feeding machine is proposed here. Content of the Utility Model

[0006] The utility model solves its technical problems by adopting the following technical solutions:
[0007] A vacuum feeding hopper for PE materials includes a vacuum pump and a vacuum suction cylinder communicated with the vacuum pump. The vacuum pump is used to evacuate the vacuum suction cylinder. A discharge cylinder is connected below the vacuum suction cylinder. It also includes a controller for controlling the vacuum pump. Additionally, it includes a moving frame. A height adjustment frame is provided on the moving frame, and the discharge cylinder is connected to the height adjustment frame and can adjust its height.
[0008] Preferably, it further includes a moving frame. Universal wheels are provided at the four corners of the lower end face of the moving frame for convenient movement, and a height adjustment arm is fixedly provided on the moving frame.
[0009] Preferably, a screw is provided in rotation in the height adjustment arm, a slider is provided in the height adjustment arm for sliding up and down, and the slider is threadedly connected to the screw. When the screw is rotated, the slider can move up and down.
[0010] Preferably, a discharge barrel fixing sleeve is fixedly provided at the front end of the sliding block for being fitted and fixed on the outside of the discharge barrel to fix it.
[0011] Preferably, a turbine is coaxially fixed on the screw, and a worm engaged with the turbine is rotatably provided on the height adjustment arm, a handwheel is coaxially fixed on the shaft end of the worm, the screw is rotated by rotating the handwheel, and the engagement of the turbine and the worm is self-locking.
[0012] Preferably, a material placement opening is provided on the movable rack for conveniently placing a container for receiving materials, so as to facilitate vertically receiving the materials discharged by the discharge barrel.
[0013] The advantages and positive effects of the utility model are: by rotating the hand wheel, the worm and the turbine can be driven to rotate efficiently and quickly, so that the screw drives the slider to move up and down, which is convenient for adjusting the height of the discharge barrel fixing sleeve according to the height of the barrel, and a material placement port is reserved at the bottom to facilitate the placement of the barrel into the receiving material.
