Description

Technical Field

[0001] The utility model relates to feeding equipment, in particular to a screw feeding machine. Background Art

[0002] The screw feeder is a feeding device commonly used in the production of food, chemical industry, etc. It generally includes an equipment frame, a silo fixedly connected to the equipment frame, a material pipe fixedly connected to the equipment frame and connected to the silo, a feeding screw rotatably connected to the material pipe, and a motor fixedly connected to the equipment frame and driving the feeding screw. Through the feeding screw, the material in the silo is lifted upward along the inclined material pipe and falls from the outlet above the material pipe. The existing screw feeder still has the following problems: the inlet position of the material pipe and the part of the feeding screw at this position are prone to residual materials, which is inconvenient to clean. Although it is very convenient to clean by opening a hatch that can be opened and closed on the opposite side of the inlet position of the material pipe, after the hatch is opened, it is difficult for this position and the inner wall of the material pipe to be as flat as when they are integrated, and materials (especially fine particles) are more likely to accumulate and get stuck in the gap. Utility Model Content

[0004] In the present application, a screw feeder is provided, comprising an equipment frame, a material bin fixedly connected to the equipment frame, a material pipe fixedly connected to the equipment frame and communicating with the material bin, a feeding screw rotatably connected to the material pipe, and a motor fixedly connected to the equipment frame and driving the feeding screw;

[0005] The silo can also slidably adjust the fixed position on the equipment frame so that the outlet flange below the silo and the inlet flange on the outer wall of the material pipe can be in a fitted state and a separated state;

[0006] When the outlet flange below the silo and the inlet flange on the outer wall of the material pipe are in a separated state and the first connecting flange of the material pipe and the second connecting flange of the reducer of the motor are disconnected, the material pipe can also rotate around its own axis to adjust its fixed position on the equipment frame.

[0030] See also Figure 1 , Figure 2 and Figure 3 A screw feeder includes an equipment frame 1, a silo 2, a material pipe 3, a feeding screw 4 and a motor 5.

[0031] The silo 2 is fixedly connected to the equipment frame 1 , and the silo 2 can also be slidably adjusted to a fixed position on the equipment frame 1 .

[0032] The material pipe 3 is fixedly connected to the equipment frame 1 and communicates with the material bin 2, that is, the outlet 3c flange 2a below the material bin 2 and the inlet flange 3a on the outer wall of the material pipe 3 are connected by fasteners. Accordingly, when the outlet 3c flange 2a below the material bin 2 and the inlet flange 3a on the outer wall of the material pipe 3 are connected, the material bin 2 cannot slide relative to the equipment frame 1 and adjust the fixed position.

[0033] After releasing the connection between the outlet flange 2a 3c below the silo 2 and the inlet flange 3a on the outer wall of the material pipe 3, the silo 2 can slide relative to the equipment frame 1, so that the outlet flange 2a 3c below the silo 2 and the inlet flange 3a on the outer wall of the material pipe 3 have a fitted state and a separated state.

[0034] See also Figure 4Optionally, the silo 2 is slidably adjusted in a horizontal direction to a fixed position on the equipment rack 1. Specifically, two steel ball slide rails may be provided between the equipment rack 1 and the silo 2.

[0035] See also Figure 1 Optionally, the silo 2 is slidably adjusted in the up-down direction to a fixed position on the equipment rack 1. For horizontal sliding, after stopping sliding, the silo 2 can be stationary relative to the equipment rack 1, and for up-down sliding, under the action of gravity, the silo 2 needs to be supported by the equipment rack 1.

[0036] Furthermore, a plurality of spacers 7 are detachably provided between the silo 2 and the equipment frame 1, and the plurality of spacers 7 can be replaced with different thicknesses. That is, by replacing the spacers 7 with different thicknesses, the outlet 3c flange 2a below the silo 2 and the inlet flange 3a on the outer wall of the material pipe 3 can be fitted or separated.

[0037] See also Figure 3 The feeding screw 4 is rotatably connected to the material tube 3. Specifically, bearings for connecting the feeding screw 4 can be provided at both ends of the material tube 3.

Specifically, the lower end of the feeding screw 4 passes through the corresponding bearing, the first connecting flange 3b of the lower end of the material pipe 3 and the second connecting flange 5b of the reducer 5a of the motor 5 are connected through fasteners, and the output shaft on the reducer 5a is connected to the lower end of the feeding screw 4.

[0039] When the outlet flange 2a 3c below the silo 2 and the inlet flange 3a on the outer wall of the material pipe 3 are separated and the first connection flange 3b of the material pipe 3 and the second connection flange 5b of the reducer 5a of the motor 5 are disconnected, the material pipe 3 can also be rotated around its own axis to adjust the fixed position on the equipment frame 1. Specifically, the equipment frame 1 is provided with a connection block 1a, and the connection block 1a has a through hole through which the material supply pipe 3 passes.

[0040] In this way, first release the connection between the outlet flange 2a 3c below the silo 2 and the inlet flange 3a on the outer wall of the material pipe 3; then slide the silo 2 so that the silo 2 will not interfere with the rotation of the material pipe 3; then rotate the material pipe 3 so that the inlet flange 3a on the outer wall of the material pipe 3 changes from tilted upward to tilted downward; finally, the area at the corresponding position in the material pipe 3 and the feeding screw 4 are cleaned through the inlet flange 3a, and cleaning liquid can also be poured into the outlet 3c of the material pipe 3, and the cleaning liquid flows out from the inlet flange 3a along the material pipe 3 to clean the material pipe 3.

[0041] See also Figure 5Optionally, the equipment rack 1 further has at least one of the following settings: Setting 1: a first limit is provided on the equipment rack 1, and when the material pipe 3 cooperates with the first limit, the inlet flange 3a on the outer wall of the material pipe 3 is tilted upward. Setting 2: a second limit is provided on the equipment rack 1, and when the material pipe 3 cooperates with the second limit, the inlet flange 3a on the outer wall of the material pipe 3 is tilted downward.

[0042] When the equipment frame 1 has both the first and second arrangements, specifically, a connecting plate 8 is fixedly connected to the outer wall of the material tube 3, the connecting plate 8 has a semicircular through groove 8a, and the connecting block 1a has a limiting column 1a1 that penetrates into the through groove 8a.
