Abstract
Description
Technical Field
[0001] This invention relates to the field of food conveying equipment, specifically a food spiral conveying device with a soft feed diversion structure. Background Technology
[0002] In food processing production lines, screw conveyors are often used to transfer food. Most existing screw conveyors use a closed cylindrical shell with a conveying screw. The food is pushed and conveyed by the screw inside the cylinder. Food located in the middle of the cylinder is easily subjected to hard compression between the screw and the inner wall of the cylinder. The soft skin of fresh food is easily damaged, which damages the integrity of the food and affects the quality of subsequent processing, resulting in material loss.
[0003] Traditional screw conveyors lack a material diversion structure in the feeding area, causing materials to accumulate in the center of the screw, which further increases the risk of food being crushed and damaged. The materials are confined to a narrow annular space with little buffer or avoidance space, making it difficult to achieve damage-free food transportation.
[0004] Some open conveyor spiral structures lack targeted feeding diversion buffer components, making it impossible to actively disperse the incoming food to both sides of the conveying channel. As a result, there is still the problem of localized pressure damage to the food, which makes it difficult to meet the production needs of refined conveying of fresh and fragile food. Summary of the Invention
[0005] The purpose of this invention is to provide a food spiral conveyor with a soft feed diversion structure to solve the problem of inconvenience in using existing food conveying equipment.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A food ingredient spiral conveying device with a soft feed diversion structure includes a hopper shell, a conveying trough for accommodating food ingredients is provided at the bottom of the hopper shell, the top of the conveying trough is open and connected to the inside of the hopper shell, and a screw for pushing food ingredients is provided inside the conveying trough, with one end of the screw extending out of the conveying trough and equipped with gears.
[0008] A guide block is fixedly installed inside the feeding area of the hopper shell. The guide block is made of soft rubber. The guide block diverts the vertically falling food to both sides of the conveying trough through the conical diversion surface to avoid the central extrusion area of the screw.
[0009] Based on the above technical solutions, the present invention also provides the following optional technical solutions:
[0010] In one alternative: a motor mounting bracket is fixedly installed on the outside of the hopper shell, and a motor is mounted on the motor mounting bracket.
[0011] In one alternative: a drive gear is provided on the output shaft of the motor, and the drive gear meshes with a gear at the end of the screw.
[0012] In one alternative: a bearing is fixedly installed on the outer side of the hopper shell, and the end of the screw passes through the inner hole of the bearing.
[0013] In one alternative, the helical surface structure of the screw is one of the following: stepped, sawtooth, smooth curved, or conical.
[0014] In one alternative, the cross-sectional shape of the conveying trough is U-shaped, square, or other irregularly shaped open trough.
[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0016] The food screw conveyor with a flexible feed diversion structure has a conical guide block inside the feed area of the hopper shell. When the food falls, it first contacts the conical diversion surface and is diverted to the left and right sides of the conveying trough. This effectively avoids the food from accumulating in the central compression area at the screw axis, eliminates the direct hard compression between the screw and the hopper shell wall, and solves the problem of food surface damage. The elastic deformation capability of the flexible material itself can absorb the impact force of the falling food, avoid rigid collision between the food and the diversion components, further protect the integrity of the food, and reduce the risk of food damage during the entire conveying process. The open structure of the conveying trough allows for real-time observation of the conveying condition, facilitates equipment cleaning and maintenance, and meets the hygiene requirements of food processing.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0022] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.
[0023] like Figure 1-3 As shown, an embodiment of the present invention provides a food spiral conveying device with a soft feed diversion structure, including a hopper shell 1. The bottom of the hopper shell 1 is provided with a conveying trough 9 for accommodating food. The top of the conveying trough 9 is open and communicates with the inside of the hopper shell 1. The inside of the conveying trough 9 is provided with a screw 8 for pushing food. One end of the screw 8 extends out of the conveying trough 9 and is provided with a gear 5.
[0024] A guide block 7 is fixedly installed inside the feeding area of the outer shell 1 of the hopper. During the falling process, the conical surface of the guide block 7 diverts the food to the left and right sides of the conveying trough 9, avoiding the food from accumulating in the central axis area of the screw. At the same time, the soft rubber has the ability to buffer deformation, avoiding rigid collision between the food and the diversion component, reducing the concentrated pressure on the food from the source, and preventing the food from being crushed by the screw and the hopper wall. The shape of the guide block 7 can be flexibly adjusted and can be square, round or any irregular shape to adapt to the conveying needs of food with different shapes.
[0025] like Figure 1-3 As shown, in a preferred embodiment of the present invention, a motor mounting base 3 is fixedly installed on the outside of the hopper shell 1, and a motor 2 is mounted on the motor mounting base 3. A drive gear 4 is provided on the output shaft of the motor 2. The drive gear 4 meshes with a gear 5 at the end of the screw 8. When it is necessary to convey the food 6, the motor 2 receives a command, the drive gear 4 rotates and drives the meshing gear 5 to rotate, thereby driving the screw 8 to rotate in the conveying groove 9. Under the action of the screw 8, the food 6 enters the conveying groove 9 and is finally conveyed out from the outlet.
[0026] like Figure 3 As shown, in a preferred embodiment of the present invention, a bearing 10 is fixedly installed on the outer side of the hopper shell 1, and the end of the screw 8 passes through the inner hole of the bearing 10.
[0027] like Figure 1 As shown, in a preferred embodiment of the present invention, the screw 8 can be stepped, sawtooth, or smooth curved, with no limit on the width of the screw blades, varying screw pitch, and can be conical, with closed or semi-closed screw blades, etc. It can adjust the conveying form according to the different softness, hardness, and size of the ingredients, taking into account both conveying efficiency and the protection effect of the ingredients, and has a wider range of applicable scenarios.
[0028] like Figure 1As shown, in a preferred embodiment of the present invention, the cross-sectional shape of the conveying trough 9 is U-shaped, square or other irregular open trough. The U-shaped open structure provides space for food to avoid being trapped between the closed cylinder wall and the screw blade, which greatly reduces the risk of food being continuously squeezed. At the same time, it is convenient to observe the conveying condition and to clean the equipment. The U-shaped trough can be extended into various irregular troughs such as square, which has strong versatility.
[0029] The above embodiments of the present invention provide a food spiral conveying device with a soft feed diversion structure. The motor 2 is driven by the drive gear 4 meshing with the end gear 5 of the screw 8. The motor 2 is arranged outside the hopper and does not occupy the feed space of the hopper. The overall structure is compact and easy to integrate into the food automated production line. The bearing 10 supports the screw to ensure the smooth rotation of the screw and the stable conveying operation.
[0030] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
