Description

Technical Field

[0001] This utility model belongs to the field of food processing technology, and in particular relates to a continuous and uniform feeding device. Background Technology

[0002] Biscuits are a popular baked good, typically made from flour, sugar, fat, and eggs as the main ingredients, mixed, shaped, and then baked. Their history dates back to ancient times, initially as a food form that was durable and easy to carry. With continuous advancements in production technology, the variety of biscuits has increased, resulting in types such as shortbread, sandwich cookies, and soft cookies. This diversification better caters to the tastes and needs of different consumers, making biscuits one of the most popular snacks worldwide. During production, it is often necessary to sprinkle toppings on the surface of the biscuits. This step not only enhances the flavor but also improves their appearance and texture. However, topping devices still have the following drawbacks in practical use:

[0003] When the spreading device spreads material onto the biscuits being conveyed, it directly spreads the material onto the biscuits. However, when different upstream conveying equipment conveys biscuit material, the conveying width of the biscuits varies. Spreading the material across the entire width directly will result in material waste and increase production costs.

[0004] Secondly, during the spreading process, the spreading device directly sprays the material onto the conveyor belt and outputs it to the biscuits that are being conveyed. During the spreading process, since a drive device is needed to drive the material to spread, the material falls onto the conveyor belt at a relatively high height, and the conveyor belt is still moving continuously, which can easily cause material to splash and affect the uniformity of spreading. Utility Model Content

[0005] The purpose of this utility model is to provide a continuous and uniform material spreading device. By setting up an upper belt conveyor, support components, a material conveying frame and a reducer, it solves the problems of the inability to control the spreading width during spreading, which increases production costs, and the problem that the material's initial velocity is not high enough during spreading, which makes it easy for it to bounce and affect the uniformity of spreading.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a continuous and uniform material spreading device, comprising an upper belt conveyor, a support assembly, a material conveying frame, and a reducer. The support assembly is fixed to the top center of the upper belt conveyor frame. The support assembly includes crossbars, mounting slots, and baffles. Mounting slots are provided on the tops of both crossbars, and two baffles are movably connected within these slots. The material conveying frame is fixed to the tops of both crossbars. A reducer is fixed to one end of the material conveying frame, and a drive shaft is fixed to the output end of the reducer. Flipping plates are fixed in a circular array around the drive shaft. The upper belt conveyor is used to convey material from the surface of biscuits. The support assembly, consisting of two crossbars with mounting slots and two movable baffles, is installed in the top center of its frame. The baffles are used to adjust the width and position of the falling material. The material conveying frame is fixed above the crossbars for temporary storage and discharge of material. The reducer is installed at one end of the material conveying frame, and its output shaft drives the flipping plates to rotate, preventing material accumulation and promoting uniform discharge.

[0008] Furthermore, several support frames are fixed at equal intervals on both sides of the upper belt conveyor frame, and a lower belt conveyor is set below the upper belt conveyor. The support frames are respectively fixed on both sides of the lower belt conveyor frame. The upper belt conveyor is installed above the lower belt conveyor through the support frames on both sides. The lower belt conveyor is used to transport the biscuits to be fed, and the upper belt is responsible for evenly spreading the material on the surface of the biscuits conveyed by the lower belt.

[0009] Furthermore, the support assembly also includes a pull plate and a fixed plate. One end of each of the two baffles is fixed with a pull plate. The pull plate is located on the outside of the crossbar. The two crossbars are fixed together between the two fixed plates. One end of the baffle is provided with a pull plate for easy pulling and adjustment. The two crossbars are connected into an integral structure through the fixed plate, which enhances the support stability and installation convenience.

[0010] Furthermore, the ends of the two crossbars are fixed to the two corners at the top of the two fixed plates on the side close to each other. The bottoms of the two fixed plates are fixed to the two long sides of the top of the upper belt conveyor frame, and the tops of the two fixed plates are respectively fixed to the two short sides of the bottom of the conveyor frame. The two ends of the crossbars are fixed to the upper corners of the fixed plates. The bottom of the fixed plates is fixed to the long side of the upper belt conveyor frame, and the top supports the short side of the conveyor frame, forming a stable cross-support structure.

[0011] Furthermore, a discharge plate is fixed at the lower edge of the conveying frame, and a feeding hopper is fixedly connected to the top of the conveying frame. The lower part of the conveying frame is provided with a discharge plate to control the discharge, and the top is equipped with a feeding hopper for receiving and centrally supplying materials.

[0012] Furthermore, the end of the drive shaft near the reducer passes through the end of the conveying frame near the reducer, and the end of the drive shaft away from the reducer is rotatably connected to the inner wall of the conveying frame. A drive motor is fixed on one side of the reducer, and the output end of the drive motor is fixed to the input end of the reducer. One end of the drive shaft passes through the conveying frame and is connected to the reducer, while the other end is rotatably supported by the inner wall of the frame. The drive motor is connected to the reducer to provide power and drive the tilting plate to continuously stir the material.

[0013] This utility model has the following beneficial effects:

[0014] This invention solves the problem of uncontrollable spreading width and increased production costs in the spreading device by setting up an upper belt conveyor, support components, and a conveying frame. The material to be spread is transported to the feed hopper and then centrally conveyed to the conveying frame. The material is then output to the upper belt conveyor via a discharge plate in the conveying frame. During operation, when the range of biscuits conveyed on the lower belt conveyor varies, baffles of different widths and numbers are inserted into the mounting slots at the top of the crossbars, allowing the discharge plate to perform discharge operations with different width ranges. This enables the spreading device to control the spreading width, reducing material waste and lowering production costs.

[0015] This invention solves the problem of insufficient initial velocity of material in the spreading device, which easily leads to bouncing and affects the uniformity of spreading, by setting up an upper belt conveyor, a conveying frame, and a reducer. The drive motor is started, which drives the reducer to work, causing the drive shaft to rotate. During the rotation of the drive shaft, the flipping plate rotates, causing the material in the conveying frame to be flipped. Simultaneously, the material is evenly dropped onto the upper belt conveyor through the discharge plate. Under the conveying action of the upper belt conveyor, it is transported to the lower belt conveyor. After the biscuits are conveyed by the lower belt conveyor, they accelerate to the same direction and speed as the lower belt conveyor, and are then transported to the lower belt conveyor, where they are evenly sprinkled onto one side of the biscuits. This ensures that the material is evenly sprinkled onto the biscuits during spreading, preventing splashing and increasing the smoothness of the conveying process. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0025] Please see Figure 1-4This utility model is a continuous and uniform material spreading device, including an upper belt conveyor 1, a support assembly 2, a material conveying frame 3, and a reducer 4. The support assembly 2 is fixed in the middle of the top of the upper belt conveyor 1 frame. The upper belt conveyor 1 is used to convey the material uniformly fed onto the surface of the biscuit. The support assembly 2 provides support for the material conveying frame 3 on the upper belt conveyor 1. The support assembly 2 includes crossbars 201, mounting grooves 202, and baffles 203. The top of each of the two crossbars 201 has a mounting groove 202. Two baffles 203 are movably connected in the mounting grooves 202 of the two crossbars 201. The crossbars 201 pass through the mounting grooves 202. The movable connecting baffle 203 restricts and determines the range and position of the material output from the discharge plate 302 by using baffles 203 of different widths. The top of the two crossbars 201 are fixed together with the conveying frame 3. The conveying frame 3 outputs the food raw materials through the discharge plate 302. A reducer 4 is fixed to one end of the conveying frame 3. A drive shaft 401 is fixed to the output end of the reducer 4. Flipping plates 402 are fixed in a ring array around the drive shaft 401. When the reducer 4 is working, it drives the drive shaft 401 to rotate. In the rotation of the drive shaft 401, the flipping plates 402 are driven to rotate. Through the rotation of the flipping plates 402, the material in the conveying frame 3 is flipped.

[0026] Specifically, several support frames 101 are fixed at equal intervals on both sides of the upper belt conveyor 1 frame, and a lower belt conveyor 102 is set below the upper belt conveyor 1. The support frames 101 are fixed on both sides of the lower belt conveyor 102 frame. When the upper belt conveyor 1 is working, it outputs the material output from the conveying frame 3. The lower belt conveyor 102 is used to directly convey the biscuits to be sprinkled. During the conveying process of the biscuits, their surface is evenly sprinkled with material.

[0027] Furthermore, the support assembly 2 also includes a pull plate 204 and a fixing plate 205. One end of each of the two baffles 203 is fixed with a pull plate 204. The pull plate 204 is located on the outside of the crossbar 201. The two crossbars 201 are fixed together between the two fixing plates 205. When the baffles 203 are in operation, they are pulled out of the mounting groove 202 of the crossbar 201 by the pull plate 204. The fixing plate 205 provides support for the material conveying frame 3.

[0028] Furthermore, the ends of the two crossbars 201 are fixed to the two corners of the upper part of the two fixing plates 205, which are close to each other. The bottom of the two fixing plates 205 is fixed to the two long sides of the top of the upper belt conveyor 1 frame, and the top of the two fixing plates 205 is fixed to the two short sides of the bottom of the conveying frame 3. When the crossbars 201 are working, they are supported on the upper belt conveyor 1 by the fixing plates 205, and the conveying frame 3 is supported on the conveying frame 3.

[0029] Furthermore, a discharge plate 302 is fixed at the lower edge of the conveying frame 3, and a feed hopper 301 is fixedly connected to the top of the conveying frame 3. The material in the conveying frame 3 is discharged through the discharge plate 302, and the material conveyed by the feed hopper 301 is concentrated and transported into the conveying frame 3.

[0030] The operation process of this embodiment is as follows: During operation, the material to be sprinkled is transported into the feed hopper 301 and then concentrated into the conveying frame 3. The material is output to the upper belt conveyor 1 through the discharge plate 302 in the conveying frame 3. During operation, when the range of biscuits conveyed on the lower belt conveyor 102 is different, baffles 203 of different widths and numbers are inserted into the mounting groove 202 at the top of the crossbar 201, so that the discharge plate 302 can perform discharge operations of different width ranges. Specific Implementation Example 2

[0031] Please see Figure 1 , 2 4, 5. Based on the specific embodiment one, the end of the drive shaft 401 near the reducer 4 passes through the end of the conveying frame 3 near the reducer 4, and the end of the drive shaft 401 away from the reducer 4 is rotatably connected to the inner wall of the conveying frame 3. A drive motor 403 is fixed on one side of the reducer 4, and the output end of the drive motor 403 is fixed to the input end of the reducer 4. When the reducer 4 is working, the power generated by the drive motor 403 drives the reducer 4 to work.

[0032] The operation process of this embodiment is as follows: During operation, the material is placed in the feeding hopper 301, and after being collected by the feeding hopper 301, it is conveyed to the conveying frame 3. At the same time, the drive motor 403 is started, and the drive motor 403 drives the reducer 4 to work, which drives the drive shaft 401 to rotate. As the drive shaft 401 rotates, it drives the flipping plate 402 to rotate, so that the material in the conveying frame 3 is flipped. At the same time, the material is flipped and evenly falls onto the upper belt conveyor 1 through the discharge plate 302. Under the conveying action of the upper belt conveyor 1, it is conveyed to the lower belt conveyor 102. After the biscuits are conveyed by the lower belt conveyor 102, they are accelerated to be consistent with the conveying direction and speed of the lower belt conveyor 102. The material is conveyed by the upper belt conveyor 1 to the surface of the biscuits on the lower belt conveyor 102 and sprinkled evenly on one side of the biscuits.
