Description

Technical Field

[0001] This utility model belongs to the field of vacuum material handling technology, and specifically relates to a vacuum material handling machine. Background Technology

[0002] Vacuum feeders are used for material conveying in injection molding machines, extruders, and blown film machines. They can automatically feed materials to these machines. When the material hopper of the central plastic feeding system is low, a signal is sent to the vacuum feeder. The vacuum feeder uses the principle of suction to transport plastic raw materials to the material hopper of the injection molding machine, extruder, or blown film machine. When the material reaches a certain level, the suction stops, and it resumes feeding when the material is insufficient.

[0003] During operation, the filter screen of a vacuum feeder is prone to clogging, which will affect the normal operation of the vacuum feeder. In existing technology, a back-flushing filter can be used to periodically clean it by introducing compressed air. The structure of existing vacuum feeders is described in the following patent:

[0004] For example, patent application number CN202020486439.0 discloses an open-type suction machine, including a horizontally arranged base plate with several rolling wheels evenly distributed on the lower surface of the base plate, a fan installed on the upper surface of the base plate, and symmetrical brackets fixed to the base plate on both sides of the fan, one of which has an air storage tank fixed to its exterior. It also includes a filter barrel located above the fan, with an internal cavity. The outer side of the filter barrel is fixed to the upper end of the bracket, a dust collection bin is installed at the bottom of the filter barrel, and a lid is installed at the top. A filter element is installed in the inner cavity of the filter barrel, with its upper end fixed to the lower surface of the lid. An electrical control box is also installed on the outer wall of the filter barrel located between the two brackets, and a material air duct is horizontally fixed to the outer wall of the filter barrel opposite the electrical control box. The air inlet of the fan is connected to the top of the lid through an exhaust pipe, and the air storage tank is connected to the filter element through a flexible hose.

[0005] For example, patent application number CN202020692516.8 discloses a vacuum material suction machine, including: a mounting frame, the mounting frame including: a first mounting plate disposed at the bottom of the mounting frame; a plurality of support rods respectively vertically disposed around the periphery of the first mounting plate; a second mounting plate disposed on the support rods and parallel to the first mounting plate; two third mounting plates respectively vertically disposed on both sides of the second mounting plate; and a filter barrel disposed on the top sides of the third mounting plates, the filter barrel having an air intake on its side wall and an air outlet on its top. The filter includes: an outlet; a connecting pipe located at the bottom of the filter bucket, with a valve on the connecting pipe and a connecting cover at the bottom of the connecting pipe; a dust collection bucket located on the second mounting plate, with several connecting buckles on the top of the dust collection bucket that fasten the connecting cover and the dust collection bucket, the dust collection bucket being connected to the filter bucket via the connecting pipe; a fan located on the first mounting plate, with an air inlet at the bottom of the fan corresponding to the air outlet, and the air outlet being connected to the air inlet; and a human-machine interface device located on the filter bucket and connected to the fan.

[0006] The existing vacuum material handling machine includes a base, support frame, fan, filter cartridge, dust collection bin, air tank, electrical control box, vacuum breaking structure, air inlet pipe, and dust removal pipe. The air tank is connected to the back-flushing air inlet of the filter cartridge via the dust removal pipe, and the fan is connected to the air outlet of the filter cartridge via an air inlet pipe with a vacuum breaking structure. The filter cartridge, dust collection bin, and fan are arranged sequentially on the support frame from top to bottom, with the bottom of the support frame located on the base. The fan is positioned horizontally, the air tank is positioned vertically on the support frame, and the electrical control box is located on the filter cartridge.

[0007] When adopting the aforementioned solution, the applicant discovered the following problems:

[0008] Firstly, the electrical control box is too high, making it inconvenient to control.

[0009] Secondly, the gas storage tank is vertically mounted on the support and cannot be too large (a large tank would not only take up space but also have a large weight).

[0010] Third, the dust collection bin is positioned high and the horizontal fan occupies a large space, making it inconvenient to operate (it is high and there is little space below). Summary of the Invention

[0011] To address the aforementioned problems, this utility model provides a vacuum material feeder. This patent adjusts the layout of various structures for easier operation. The air storage tank is horizontal and mounted on a base, allowing for a larger capacity. The blower is vertically positioned, facilitating pipeline layout and maintenance.
