Description

Technical Field

[0001] This utility model relates to the technical field of powder material conveying equipment, specifically to a spiral feeding device. Background Technology

[0002] Powders such as putty powder and dry mortar need to be conveyed multiple times during the production process, which may contain small amounts of impurities, or some powder may clump due to moisture. These impurities and clumps can affect product quality. In existing technology, factories set up special fine screening equipment at the discharge end of the production line. The material discharged from the discharge end needs to be finely screened by the fine screening equipment before final packaging.

[0003] However, the equipment in powder production sites is large in size, with complex and heavy structures. Fine screening equipment, as a permanent standby device, occupies a significant amount of space. As the final stage of the entire production line, a malfunction in the fine screening equipment will affect the operation of upstream equipment and even the entire production line. Utility Model Content

[0004] The purpose of this invention is to provide a spiral feeding device that can move flexibly and be used in conjunction with the discharge end of the production line as needed, so as to be connected as needed and without occupying factory space.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A spiral feeding device includes a base, which comprises a lower frame and an upper frame. The lower frame and the upper frame are fixedly connected by a buffer structure. Four vibration springs are fixedly connected to the top side of the upper frame, and a vibrating bucket is fixedly connected to the four vibration springs. A receiving hopper is fixedly connected to the upper opening of the vibrating bucket. A screen is sandwiched between the upper opening edge of the vibrating bucket and the lower opening edge of the receiving hopper. A vibrating motor is fixedly connected to the top side of the upper frame. A mounting cylinder is provided on one side of the vibrating bucket. A bearing is provided inside the mounting cylinder, and an eccentric shaft is supported by the bearing. An input pulley is fixedly connected to the outer end of the eccentric shaft. The pulley of the vibrating motor is connected to the input pulley via a belt drive. The lower frame has two forward-extending... An extension beam is extended, and an inclined support is fixed to the extension beam. Two reinforcing vertical beams connect the extension beam and the inclined support. The inclined support includes four longitudinal bars and several transverse frames. Several connecting pieces are fixed between the two longitudinal bars on the bottom side. The top edge of the connecting pieces is provided with a contoured notch. Multiple connecting pieces are fixed together to a spiral conveyor cylinder. The spiral conveyor cylinder passes through multiple transverse frames. A screw is rotatably installed inside the spiral conveyor cylinder. The screw is provided with spiral blades. A feeding motor is fixed to the bottom end of the inclined support. The motor shaft of the feeding motor is connected to the screw via chain drive. The bottom wall of the top of the spiral conveyor cylinder is provided with a discharge port, which is located at the top opening of the receiving hopper.

[0007] Specifically, the angle between the screw and the horizontal plane is 50° to 60°.

[0008] Specifically, the bottom ends of the two upper vertical strips are fixed with guide plate frames, and the lower side of the guide plate frames is inclined inward.

[0009] Specifically, the screw conveyor includes a bottom trough and a top cover. The bottom of the bottom trough has an arc-shaped cross-section, and the screw is rotatably located inside the bottom trough. The top cover is fixed to the top side opening of the bottom trough by screws, and the bottom end of the top cover is provided with a feed inlet, which is located below the lower side opening of the guide plate frame.

[0010] Specifically, the lower section of the vibrating bucket is a tapered cylinder that narrows downwards. The tapered cylinder passes through the upper frame. The side wall of the vibrating bucket is provided with a mounting flange. The mounting flange is square, and the bottom wall of each of the four corners of the mounting flange is fixed to a vibrating spring.

[0011] Specifically, connecting blocks are fixed to the upper and lower ends of the vibration spring.

[0012] Specifically, multiple bolts are circumferentially threaded through the upper opening edge of the vibrating bucket, and multiple bolts pass through the edge of the screen.

[0013] Specifically, the buffer structure includes an upper connecting plate and a lower connecting plate, which are connected by an ACF column.

[0014] Specifically, a discharge hopper is fixed to the bottom side of the lower frame.

[0015] Specifically, four legs are fixed to the bottom side of the lower frame, and the four legs are inclined in four directions. The lower end of the legs is fixed with an electrically controlled roller.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This spiral feeding device is used for loading and packaging powders such as putty powder and dry mortar. During operation, the spiral feeding device enters the discharge end of the production line in the powder production plant, aligns the discharge end of the production line with the guide frame 54, and then the electrically controlled roller 14 is locked, bringing it to a stop, thereby fixing the spiral feeding device in a fixed state.

[0018] A bag support frame (not shown) is placed under the discharge hopper 13. A packaging bag of suitable size is hung on the bag support frame, which is used to open the bag opening.

[0019] Then, the powder is discharged from the discharge end of the production line. The powder is guided into the feed inlet 64 by the guide plate frame 54, and the screw 61 drives the powder to be conveyed upward along the inner wall of the bottom groove 601. The angle between the screw 61 (bottom groove 601) and the horizontal plane is 50° to 60°. This angle utilizes the component of gravity of the powder, which can reduce the adhesion of the powder to the inner wall of the bottom groove 601, thereby making the transmission smoother.

[0020] The powder is fed into the receiving hopper 41 through the discharge port 63. The vibrating hopper 4 is floatingly connected to the upper frame 2: four vibration springs 21 are fixed to the top side of the upper frame 2, and all four vibration springs 21 are connected to the vibrating hopper 4. An installation cylinder 43 is provided on one side of the vibrating hopper 4 (see...). Figure 5 The mounting cylinder 43 is equipped with a bearing (not shown in the figure), which supports an eccentric shaft (not shown in the figure). An input pulley 44 is fixed to the outer end of the eccentric shaft. The pulley of the vibration motor 22 is connected to the input pulley 44 through belt drive.

[0021] The vibrating motor 22 drives the eccentric shaft to rotate, thereby causing the vibrating bucket 4 to vibrate relative to the upper frame 2, thus facilitating the smoother passage of the powder in the receiving hopper 41 through the screen 42 (see...). Figure 6 Small impurities or lumps in the powder will be blocked by the screen 42 and remain in the receiving hopper 41. Powder that meets the size requirements and passes through the screen 42 enters the discharge hopper 13 and then falls into the packaging bag provided below the discharge hopper 13.

[0022] Because the powder passes through screen 42 for fine screening before entering the bag, the quality of the packaged product is guaranteed. This screw feeder is a mobile device that can be quickly driven to the discharge end of the production line where packaging is required for fine screening. After packaging is completed, it can be driven away immediately without occupying limited factory space. The system can intelligently control the direction and speed of the electrically controlled roller 14 and lock it, enabling the screw feeder to move flexibly.

[0023] The buffer structure 3 includes an upper connecting plate and a lower connecting plate. The upper connecting plate and the lower connecting plate are connected by an ACF column 31. The ACF material has excellent vibration damping and buffering performance, which can greatly reduce the vibration of the vibrating bucket 4 on the lower frame 1 and the electrically controlled roller 14, making the device work stably and safely.

[0055] A bag support frame (not shown) is placed under the discharge hopper 13. A packaging bag of suitable size is hung on the bag support frame, which is used to open the bag opening.

[0056] Then, the powder is discharged from the discharge end of the production line. The powder is guided into the feed inlet 64 by the guide plate frame 54, and the screw 61 drives the powder to be conveyed upward along the inner wall of the bottom groove 601. The angle between the screw 61 (bottom groove 601) and the horizontal plane is 50° to 60°. This angle utilizes the component of gravity of the powder, which can reduce the adhesion of the powder to the inner wall of the bottom groove 601, thereby making the transmission smoother.

An input pulley 44 is fixed to the outer end of the eccentric shaft. The pulley of the vibration motor 22 is connected to the input pulley 44 through belt drive.

[0058] The vibrating motor 22 drives the eccentric shaft to rotate, thereby causing the vibrating bucket 4 to vibrate relative to the upper frame 2, thus facilitating the smoother passage of the powder in the receiving hopper 41 through the screen 42 (see...). Figure 6 Small impurities or lumps in the powder will be blocked by the screen 42 and remain in the receiving hopper 41. Powder that meets the size requirements and passes through the screen 42 enters the discharge hopper 13 and then falls into the packaging bag provided below the discharge hopper 13.

[0059] Because the powder passes through screen 42 for fine screening before entering the bag, the quality of the packaged product is guaranteed. This screw feeder is a mobile device that can be quickly driven to the discharge end of the production line where packaging is required for fine screening. After packaging is completed, it can be driven away immediately without occupying limited factory space. The system can intelligently control the direction and speed of the electrically controlled roller 14 and lock it, enabling the screw feeder to move flexibly.
