Description

Technical Field

[0001] The utility model relates to the technical field of food processing, and particularly relates to a spiral material spreading mechanism. Background Art

[0002] The spiral powder spreading mechanism is a device for uniformly spreading materials, and is mostly used in drum flavoring machines. At present, the spiral powder spreading mechanisms on the market mainly rely on a dragon conveyor for transmission. The dragon conveyor mainly includes a rotating shaft, spiral blades and a conveying pipe. The rotating shaft drives the spiral blades to rotate circularly in the conveying pipe, and the rotating spiral blades push the materials to be conveyed.

[0003] The existing spiral powder spreading mechanism with the above structural form has the following problems: The rotating shaft is fixed by a motor, and there is no positioning or adjusting device at the end. If the distance between the rotating shaft and the pipe is too close, the spiral blades are prone to friction with the pipe, generating metal powder, which poses a food safety hazard; if the gap between the rotating shaft and the bottom of the pipe is too large, it will cause material residue and is difficult to clean. Summary of the Invention

[0004] The utility model provides a spiral material spreading mechanism for solving the problem that the rotating shaft of the dragon conveyor in the spiral powder spreading mechanism cannot be adjusted, which easily brings food safety hazards. The spiral material spreading mechanism is convenient for debugging and installation, applicable to various materials, effectively avoids the friction between the spiral blades and the pipe, and reduces the risk of food safety.

[0005] In order to achieve the above purpose, the technical solution of the utility model is:

[0006] A spiral material spreading mechanism includes a dragon conveyor. The dragon conveyor includes a conveying pipe. A rotating shaft is arranged in the conveying pipe axially. Spiral blades are arranged on the rotating shaft axially. A hopper is communicated with the conveying pipe. An adjusting plate is arranged at the outlet of the conveying pipe. The adjusting plate is used for adjusting the height of the rotating shaft. The upper part of the adjusting plate is detachably connected with the conveying pipe, and the lower part is rotatably connected with the rotating shaft. Sieve holes are arranged at the bottom of the conveying pipe near the outlet. By adjusting the height of the adjusting plate on the conveying pipe, the height of the rotating shaft is adjusted. The sieve holes are convenient for uniformly spreading materials.

[0007] Further, one end of the conveying pipe is provided with an adjusting plate, and the other end is provided with a mounting plate. A motor is arranged on one side of the mounting plate. The motor drives the rotating shaft to rotate in the conveying pipe. The mounting plate is used for fixing the motor.

[0008] Further, a fixing plate matched with the adjusting plate is fixedly arranged on the conveying pipe. The fixing plate and the adjusting plate are connected by bolts. Circular holes matched with the bolts are opened on the fixing plate, and vertical waist-shaped holes matched with the bolts are opened on the adjusting plate. The height of the adjusting plate on the conveying pipe is adjusted by bolts.

[0009] Furthermore, the adjusting plate is in an inverted triangular shape. There are two vertical waist holes provided in the upper part of the adjusting plate, and a circular hole matching the rotating shaft is opened in the lower part of the adjusting plate. The rotating shaft rotates relative to the adjusting plate within the circular hole.

[0010] Furthermore, the bottom of the adjusting plate is higher than the lower surface of the conveying pipeline. Materials can leave the conveying pipeline from the gap between the adjusting plate and the conveying pipeline to cope with the situation where the amount of scattered materials is too large and the sieve holes cannot completely let the conveyed materials fall, thus avoiding the situation where materials accumulate and cause excessive operating resistance of the motor and burn the motor.

[0011] Furthermore, a bushing is provided between the adjusting plate and the rotating shaft. The bushing is in interference fit with the adjusting plate and in clearance fit with the rotating shaft. The bushing plays a cushioning role to prevent friction between the adjusting plate and the rotating shaft during use.

[0012] Furthermore, the upper part of the hopper is cylindrical and the lower part is in an inverted conical shape. A quick-release clamp is provided at the connection between the hopper and the conveying pipeline. It can be quickly disassembled and assembled, facilitating cleaning.

[0013] Through the above technical solutions, the beneficial effects of the present utility model are as follows:

[0014] 1. In the present utility model, an adjusting plate with adjustable height is provided at the end of the conveying pipeline. The adjusting plate is rotationally connected to the rotating shaft. By controlling the height of the adjusting plate, the distance between the rotating shaft and the inner wall of the conveying pipeline can be adjusted, thus avoiding the problems of friction between the spiral blade and the inner wall of the conveying pipeline or excessive gaps causing material accumulation, and reducing the risk of food safety.

[0015] 2. A gap is left between the adjusting plate and the bottom of the conveying pipeline. Sieve holes are provided at the bottom of the conveying pipeline. During the transportation of materials, a part of the materials fall through the sieve holes, and the remaining materials can leave the conveying pipeline from below the adjusting plate, avoiding the situation where materials accumulate at the end of the conveying pipeline and cause excessive operating resistance of the motor and burn the motor.

[0023] The present utility model will be further described below in conjunction with the drawings and specific embodiments:

[0024] As Figures 1 to 6 shown, this embodiment provides a spiral feeding mechanism, including an auger conveyor. The auger conveyor includes a conveying pipeline 2. A rotating shaft 21 is arranged in the conveying pipeline 2. A spiral blade 22 is axially arranged on the rotating shaft 21. The rotating shaft 21 drives the spiral blade 22 to rotate, thereby pushing the material to move horizontally in the conveying pipeline 2. A hopper 1 is communicated with the conveying pipeline 2. The material enters the conveying pipeline 2 from the hopper 1 and leaves the conveying pipeline 2 from one end of the conveying pipeline 2 under the conveyance of the spiral blade 22.

[0025] An adjusting plate 5 is arranged at the outlet of the conveying pipeline 2. The adjusting plate is used to adjust the height of the rotating shaft 21. The upper part of the adjusting plate 5 is detachably connected to the conveying pipeline 2, and the lower part is rotatably connected to the rotating shaft 21. Sieve holes are arranged at the bottom of the conveying pipeline 2 near the outlet. As an implementable manner, the adjusting plate 5 is slidably connected to the conveying pipeline 2. A fastener is arranged between the adjusting plate 5 and the conveying pipeline 2. The fastener enables the adjusting plate 5 to switch between a moving state and a fixed state.

[0026] The main body of the conveying pipeline 2 is cylindrical. The central axis of the cylinder is parallel to the horizontal plane. The hopper 1 is arranged at the top of the conveying pipeline. The hopper 1 is connected to the conveying pipeline 2 through a pipeline. An adjusting plate 5 is arranged at one end of the conveying pipeline 2, and a mounting plate 3 is arranged at the other end. The mounting plate 3 is plate-shaped. The length and width of the mounting plate 3 are both larger than the diameter of the main body of the conveying pipeline 2. A motor is arranged on one side of the mounting plate 3 away from the conveying pipeline 2. The motor is connected to the rotating shaft 21. The motor drives the rotating shaft 21 to rotate in the conveying pipeline 2.

[0027] A fixing plate 4 matching the adjusting plate 5 is fixedly arranged on the conveying pipeline 2. The fixing plate 4 and the adjusting plate 5 are connected by bolts. Circular holes matching the bolts are opened on the fixing plate 4, and vertical waist-shaped holes matching the bolts are opened on the adjusting plate 5. Loosen the bolts, and the adjusting plate 5 can be moved up and down to adjust the height of the adjusting plate 5 on the conveying pipeline 2. After adjusting to the appropriate height, tighten the bolts to fix the adjusting plate 5.

[0028] As an implementable mode, the adjusting plate 5 is in an inverted triangle shape. A total of two vertical waist holes are provided at the upper part of the adjusting plate 5, and a circular hole matching the rotating shaft 21 is opened at the lower part of the adjusting plate 5. In order to avoid friction between the adjusting plate 5 and the rotating shaft 21, a bushing is arranged between the adjusting plate 5 and the rotating shaft 21. The bushing is in interference fit with the adjusting plate 5 and in clearance fit with the rotating shaft 21. The bushing is a matching part used outside mechanical components to achieve functions such as sealing and wear protection, and refers to a ring sleeve that acts as a gasket. In this embodiment, a bushing made of nylon material is selected because it has characteristics such as wear resistance and self-lubrication.

[0029] The bottom of the adjusting plate 5 is higher than the lower surface of the conveying pipeline 2, so that excess materials can leave the conveying pipeline 2 from below the adjusting plate 5, avoiding the situation where materials cannot completely fall from the sieve holes and accumulate at the end of the conveying pipeline 2, resulting in excessive resistance to the operation of the motor and burning out the motor.

[0030] The upper part of the hopper 1 is cylindrical and the lower part is in an inverted conical shape. A quick-release clamp 11 is arranged at the connection between the hopper 1 and the conveying pipeline 2. The quick-release clamp 11 is a connecting device for connecting pipe fittings, valves with grooves and pipeline fittings. Generally, the joint is provided with gaskets, rubber, silica gel and PTFE, and it has good performance, high sealing degree and is easy to install. In this embodiment, the conventional model of the quick-release clamp 11 can be used, which belongs to well-known technology and will not be elaborated here.

[0031] During use, materials are put into the conveying pipeline 2 from the hopper 1, the motor drives the rotating shaft 21 to rotate, the spiral blade 22 drives the materials and transports the materials to the outlet. Part of the materials fall through the sieve holes at the bottom of the conveying pipeline 2, and the remaining materials leave the conveying pipeline 2 from the gap between the adjusting plate 5 and the conveying pipeline 2, avoiding the situation where materials accumulate at the end of the conveying pipeline 2, resulting in excessive resistance to the operation of the motor and burning out the motor.

[0032] By adjusting the height of the adjusting plate 5 on the conveying pipeline 2, the distance between the rotating shaft 21 and the bottom of the conveying pipeline 2 can be controlled, thereby avoiding the situation where the distance between the spiral blade 22 and the conveying pipeline 2 is too close to cause friction, or the distance between the spiral blade 22 and the conveying pipeline 2 is too far to cause material accumulation.

[0033] The above embodiments are only the preferred embodiments of the present invention, and do not limit the implementation scope of the present invention. Therefore, any equivalent changes or modifications made according to the structure, features and principles described in the scope of the present invention patent should be included in the scope of the patent application of the present invention.
