Description

Technical Field

[0001] The invention relates to the field of feeding equipment, in particular to a parallel spiral roller forced feeder. Background Art

[0002] The screw feeder is a common material conveying equipment. It mainly transports materials from one place to another along the conveying pipe or trough through the screw body. It is usually used in the material conveying process of cement, food processing, chemical industry, metallurgy, building materials and other industries. The screw feeder is usually composed of a screw body, a bearing, a transmission device and a discharge port. The material enters the screw body of the pipe or trough and is pushed to the discharge port under the action of the screw driving force. The screw conveyor has the advantages of simple structure, small footprint, large conveying capacity, and is suitable for conveying a variety of materials. The existing screw feeder is usually a single screw conveyor. The material enters between the screw blades and is continuously squeezed and conveyed forward. Therefore, it is easy for materials to accumulate and block during use. In addition, the discharge port of the existing screw feeder is mainly designed at the end of the screw body. The material is delivered to the discharge port in the direction of the one-way conveying of the screw body. The conveying capacity of the one-way conveying is limited, which restricts the feeding efficiency. Summary of the invention

Implementation

[0014] Example 1, see the attached specification Figure 1-5 A parallel spiral roller forced feeder comprises a feeding trough 12 mounted on a bracket 11 and a plurality of feeding roller groups arranged side by side in the feeding trough 12. The upper port of the feeding trough 12 adopts a closing structure, so that the material is not easy to be spilled during the feeding process. Each feeding roller group comprises a first spiral roller 13 and a second spiral roller 14 arranged side by side. The two spiral rollers are arranged side by side horizontally, and the two spiral rollers are close to the bottom of the feeding trough 12. The two ends of the first spiral roller 13 and the second spiral roller 14 are respectively rotatably connected to the bottom of the two end plates 122 of the feeding trough 12. One end of the first spiral roller 13 is provided with a spiral blade A 151, and the other end is provided with a spiral blade A 151 in the same direction as the spiral blade A 151. The spiral blade A 151 and the spiral blade B 152 have the same length, a spiral blade C 153 is provided at one end of the second spiral roller 14, and a spiral blade D 154 is provided at the other end in the opposite direction to the spiral blade C 153, the spiral blade C 153 and the spiral blade D 154 have the same length, and the length of the spiral blade C 153 is the same as the length of the spiral blade A 151, the spiral blade C 153 and the spiral blade A 151 have opposite spiral directions and corresponding positions, the spiral blade D 154 and the spiral blade B 152 have opposite directions and corresponding positions, and a driving device for driving the feeding roller group to rotate is provided on the bracket 11; The middle part of the bottom of the feeding trough 12 is provided with a discharge port 121 along its width direction, and the discharge port 121 corresponds to the middle part of the first spiral roller 13 and the second spiral roller 14. After the material enters the feeding trough 12, the spiral blades at both ends of the spiral roller will synchronously transport the material to the middle discharge port 121 in opposite directions. The spiral roller has the function of bidirectional synchronous transportation, which greatly improves the feeding efficiency.

[0015] A gap A16 is provided between the spiral blade A 151 and the spiral blade B 152, and a gap B17 is provided between the spiral blade C 153 and the spiral blade D 154. The gap A16 and the gap B17 have the same size and corresponding positions, and the position of the discharge port 121 is directly opposite to the gap A16 and the gap B17 up and down, and the discharge port 121 can cover the gap A16 and the gap B17. During the bidirectional conveying process of the spiral blades at both ends of the spiral roller, the materials on both sides are continuously and synchronously extruded and conveyed to the gap, and the conveying stops when they arrive at the gap and they are squeezed and contacted with each other, and are forcibly sent out from the discharge port 121 below the gap.

[0016] The driving device is a plurality of reduction motors 18, which are fixedly mounted on the outer side of the end plate 122. The auger shaft of the first spiral roller 13 or the second spiral roller 14 is coaxially connected to the driving shaft of the reduction motor 18. The reduction motor 18 drives the first spiral roller 13 and the second spiral roller 14 to rotate in opposite directions to achieve efficient feeding. Combined with the spiral blades of the first spiral roller 13 and the second spiral roller 14 arranged in opposite directions at corresponding positions, the feeder can mix and stir the materials while feeding, thereby improving the feeding effect and making the feeder suitable for materials with poor fluidity or large particles, and having stronger applicability.

[0017] The bottom surface of the feeding trough 12 is provided with a plurality of U-shaped seats 111 along its width direction, and both ends of the U-shaped seats 111 extend to the two side walls of the feeding trough 12. The feeding trough 12 is firmly connected to the upper end of the bracket 11 through the U-shaped seats 111, and the U-shaped seats 111 can also play a role in reinforcing the feeding trough 12 to prevent the feeding trough 12 from being squeezed and deformed.

[0018] The working process and principle of the present invention are as follows: a plurality of reduction motors 18 at the ends of the feeding trough 12 are started simultaneously, and the first spiral roller 13 and the second spiral roller 14 in the feeding roller group are driven by the reduction motor 18 to rotate in opposite directions. Since the spiral blades of the first spiral roller 13 and the second spiral roller 14 in the feeding roller group are in opposite directions, the first spiral roller 13 and the second spiral roller 14 can cooperate in feeding efficiently, and the spiral blades rotating in opposite directions also have the function of mixing and stirring the materials, so the feeding effect is better. During the feeding process, the spiral blades at both ends of the first spiral roller 13 and the second spiral roller 14 with opposite directions will convey the materials to the middle of the feeding trough 12 in opposite directions, and the materials are continuously and synchronously extruded and conveyed to the gap A16 or the gap B17, and forced to be synchronously sent out from the discharge port 121 below, so that the feeding amount is large and the feeding efficiency is high.
