Description

Technical Field

[0001] The present invention relates to the technical field of color sorters, and particularly to a material receiving device used on a color sorter. Background Art

[0002] A color sorter is a device that automatically sorts out different-colored particles of materials according to the differences in the optical properties of the materials, using the photoelectric detection technology field. The sorted materials often discharge through a receiving pipe. However, a large amount of air flow will be generated during this process. Especially when encountering the confined and narrow space of the material receiving device, the air flow generated during the falling process of the materials will cause dust to swirl and rise, which will interfere with the normal color sorting work, and there are also problems of splashing and overflowing of the falling materials. Summary of the Invention

[0003] The purpose of the present invention is to solve the shortcomings existing in the prior art, and to propose a material receiving device used on a color sorter.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A material receiving device used on a color sorter includes a hopper. A transition hopper is provided at the bottom of the transition hopper. An additional hopper is provided at one end of the transition hopper away from the hopper. A transition housing is provided on the side of the transition hopper. A net plate is movably installed on one side of the transition housing close to the opening of the additional hopper for intercepting the materials overflowing from the opening of the additional hopper. A knocking cam is movably installed inside the transition housing for reciprocally knocking the side of the net plate. It further includes a driving component for driving the knocking cam to rotate. A buffer air bag is installed on the side of the net plate away from the transition hopper for buffering and shock-absorbing the side of the net plate. A dust suction pipe is provided at one end of the transition housing for sucking the dust in the falling materials in the additional hopper.

[0006] Preferably, a return spring is installed inside the buffer air bag for resetting the deformation of the buffer air bag during the process of the net plate being knocked by the knocking cam.

[0007] Preferably, a blowing pipe is provided on the side of the additional hopper away from the transition housing. It further includes an extension pipe. One end of the extension pipe is communicated with the inside of the buffer air bag, and the other end of the extension pipe is communicated with the inside of the blowing pipe for delivering the compressed air in the buffer air bag to the inside of the blowing pipe when the buffer air bag is squeezed.

[0008] Preferably, an air inlet pipe is provided on one side of the buffer air bag. The end of the air inlet pipe away from the buffer air bag extends to the outside of the transition housing for introducing air into the buffer air bag when the buffer air bag is stretched.

[0009] Preferably, the blowing pipe is inclined.

[0010] Preferably, a first one-way valve is installed at one end of the soot blowing pipe to prevent air from being introduced into the buffer airbag through the soot blowing pipe and the extension pipe when pulling the buffer airbag; a second one-way valve is installed at one end of the air inlet pipe to prevent the air in the buffer airbag from being discharged through the air inlet pipe when squeezing the buffer airbag.

[0011] Preferably, a movable plate is movably installed inside the additional hopper.

[0012] Preferably, a guiding groove is formed on the inner wall of the additional hopper to guide the movement of the movable plate when adjusting the inclination angle of the movable plate.

[0013] The beneficial effects of the present invention are as follows:

[0014] During use, the materials after color sorting in the color sorter will fall into the hopper and then fall into the additional hopper through the transition hopper, realizing the receiving of the materials sorted by the color sorter. During the receiving process, the dust in the materials falling in the additional hopper can be sucked through the dust suction pipe, and the airflow generated by the falling of the materials can also be led out through the dust suction pipe, realizing the dust suction treatment of the materials while receiving the materials. At the same time, the mesh plate limits and intercepts the materials overflowing from the opening of the additional hopper to prevent the materials from overflowing or splashing out from the opening of the additional hopper. The driving component can be used to drive the knocking cam to rotate, reciprocally knock the side of the mesh plate, causing the mesh plate to vibrate, promoting the materials splashed onto the mesh plate to fall back into the additional hopper. At the same time, the vibrating mesh plate can effectively shake off the dust in the mesh holes of the mesh plate, preventing the dust from blocking the mesh holes of the mesh plate and affecting the dust suction effect of the dust suction pipe. During the knocking process of the mesh plate, the buffer airbag buffers and dampens the side of the mesh plate to prevent the side of the mesh plate from colliding with the inner wall of the transition housing.
