Description

Technical Field

[0001] The utility model relates to an auxiliary feeding device for powder materials. Background Art

[0002] In the pharmaceutical field, negative pressure conveying is widely used in the production process of oral solid preparations. However, when conveying materials, the current negative pressure conveyors accumulate materials in the feeding hose, causing pipeline blockage and affecting production efficiency. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide an auxiliary feeding device for powder materials, which is used to solve the problem that materials in a feeding hose are accumulated in the feeding hose, resulting in pipeline blockage.

[0004] In order to solve the above problems, the utility model provides an auxiliary feeding device for powder, including a base, on which a plurality of cylinders are arranged in sequence, a limiting piece is connected to the cylinder piston rod, a feeding hose is arranged in the limiting piece, and each cylinder is respectively controlled to extend and retract by a solenoid valve, and each solenoid valve is connected to the output end of the controller.

[0005] The limiting member comprises a support fixedly connected to the cylinder piston rod, two groove wheels are mounted on the support, and the feeding hose is arranged between the two groove wheels.

[0006] A slot hole is provided on the support, and a rotating shaft at one end of the groove wheel is assembled in the slot hole.

[0007] The beneficial effects of the utility model are as follows: the feeding hose is arranged in a limit piece, and the limit piece is driven by the cylinder to move up and down, thereby shaking the feeding hose, causing the material to jump in the feeding hose to reduce contact with the tube wall, avoiding accumulation, and sucking the material into the designated container under the action of the negative pressure of the source system. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] The utility model is further described below in conjunction with the accompanying drawings:

[0009] Figure 1 It is a structural schematic diagram of the utility model.

[0010] Figure 2 This is a schematic diagram of the connection between the cylinder and the controller of the utility model.

[0011] In the figure: base 1, cylinder 2, bellows 3, groove wheel 41, support 42, slot hole 43. DETAILED DESCRIPTION

[0012] like Figure 1 and 2As shown, an auxiliary feeding device for powder material comprises a base 1, on which a plurality of cylinders 2 are arranged and installed in sequence, a limiter 4 is connected to the piston rod of the cylinder 2, a feeding hose is arranged in the limiter 4, and each cylinder 2 is respectively controlled to extend and retract by a solenoid valve, and each solenoid valve is connected to the output end of the controller. The feeding hose is a PVC steel wire corrugated hose. The controller is a PLC controller. During implementation, the controller controls each cylinder 2 to reciprocate up and down, and the reciprocating stroke is 20-50 mm, so that the powder material in the corrugated hose shakes up and down. When the powder material jumps up, it is sucked away by the negative pressure tube, so that the material jumps in the feeding hose to reduce the contact with the tube wall, avoid accumulation, and suck the material into the designated container under the action of the negative pressure of the source system.

[0013] The position-limiting member 4 comprises a support 42 fixedly connected to the piston rod of the cylinder 2, on which two groove wheels 41 are mounted, and the feeding hose is arranged between the two groove wheels 41. This structure can limit the position of the bellows while allowing the bellows to move between the groove wheels 41, thereby preventing the shaking sections of the bellows from being entangled with each other.

[0014] A slotted hole 43 is provided on the support 42, and one end of the sheave 41 is assembled in the slotted hole 43 through a nut. This structure can facilitate the assembly of the bellows and the adjustment of the gap of the bellows.

[0015] The above embodiments are only preferred technical solutions of the present invention and should not be regarded as limitations of the present invention. The protection scope of the present invention shall be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
