Description

Technical Field

[0001] The utility model relates to the technical field of food processing, in particular to a full-automatic rolling machine. Background Art

[0002] With the continuous advancement of food research and development and manufacturing technology, a variety of foods have added a lot of color to people's lives. Often, some foods are coated with a layer of supplementary food, such as meat floss on the surface of bread, bread crumbs on the surface of chicken, fish, seafood, chicken legs, chicken wings or onion rings, and sesame and bread crumbs on the surface of glutinous rice balls, meatballs or sesame balls.

[0003] During the rolling process in factory production, a rolling machine is often used to roll the food, coating the surface of the food with a supplementary ingredient. When rolling food, the food to be rolled (such as bread) and the supplementary ingredients (such as pork floss) must first be prepared. The food and supplementary ingredients are then placed in the same rolling container and rolled, coating the outer surface of the food with the supplementary ingredients and forming a semi-finished product. The semi-finished product then rolls out of the rolling machine's outlet and falls onto a conveyor belt. Finally, the semi-finished product is transported by the conveyor belt to the production equipment for the next production process, completing the entire rolling process.

[0004] However, the existing rolling machines have the following problems:

[0005] In the process of the semi-finished product rolling out of the material outlet of the rolling machine and falling onto the conveyor belt, some rolling auxiliary materials that are not wrapped on the food to be rolled will be brought out and fall onto the conveyor belt together. At the same time, in the process of the semi-finished product falling onto the conveyor belt and being transported to the production equipment of the next production process by the conveyor belt, some rolling auxiliary materials will also fall from the surface of the semi-finished product. However, if these rolling auxiliary materials that are brought out by the semi-finished product and not wrapped on the food to be rolled and the rolling auxiliary materials that fall from the surface of the semi-finished product are to be reused, they need to be collected manually, which wastes manpower; if they are not recycled, the utilization rate of the bread crumbs will be relatively low.

[0006] In view of this, the applicant conducted an in-depth study on the above issues, which led to the emergence of this case. Utility Model Content

[0061] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0062] like Figures 1-6 As shown, this embodiment provides a fully automatic rolling machine, including a rolling device 100 and a conveying device, and the conveying device includes a feeding conveying device, a discharging conveying device 300 and a returning conveying device 400.

[0063] The rolling device 100 includes a rolling base 110, a rolling barrel 120 rotatably arranged on the rolling base 110, and a driving motor 130 for driving the rolling barrel 120 to rotate. The rolling barrel 120 has a rolling cavity. The axis of the rolling barrel 120 is arranged inclined compared to the horizontal plane. An inlet and outlet are provided at one end of the rolling barrel 120 which is relatively low in the axial direction. The inlet and outlet are connected to the rolling cavity. In this embodiment, a feed port is also provided at one end of the rolling barrel 120 which is relatively high in the axial direction.

[0064] For the sake of convenience, the food to be rolled is defined as the main food, and the outer surface of the main food is coated with the rolling auxiliary material to form a semi-finished product.

[0065] The roller 120 includes an octagonal roller 121 and an outer roller 122 mounted on the octagonal roller 121. The axis of the octagonal roller 121 is tilted relative to the horizontal plane, and the outer roller 122 is coaxial with the octagonal roller 121 and fixed to the octagonal roller 121. The octagonal roller 121 includes eight side wall units 124, which are connected end to end in a closed loop. The roller cavity is enclosed by the eight side wall units 124. The cross-section of the roller cavity is a regular octagon, and the roller cavity is approximately in the shape of a regular octagonal prism. A first mold plate 126 is fixed to one end of the octagonal roller 121 at a relatively high position in the axial direction. In this embodiment, the outer contour of the first mold plate 126 is a regular octagon. The first mold plate 126 covers the rolling cavity. The eight sides of the first mold plate 126 are arranged in a one-to-one correspondence with the eight side wall units 124 of the octagonal roller 121. The eight sides of the first mold plate 126 are respectively fixedly connected to the corresponding side wall units 124, wherein the feed port is opened on the first mold plate 126, and the outer contour of the feed port is circular.

[0066] The octagonal roller 121 is provided to facilitate the tumbling of non-spherical main foods in the rolling cavity, such as cube-shaped bread, chicken nuggets, chicken wings, etc.

[0067] Furthermore, a baffle 125 is fixed on at least one side wall unit 124. The baffle 125 is arranged obliquely compared to the axis of the rolling barrel 120. The baffle 125 is located in the rolling cavity. In this embodiment, there are four baffles 125. Specifically, among the eight side wall units 124, there is a side wall unit 124 with a baffle 125 fixed thereto and arranged accordingly for every other side wall unit 124. By setting the baffle 125, when the roller 120 rolls, when one of the baffles 125 rotates to the bottom of the axis of the roller 120, the baffle 125 can push the main food, semi-finished product and rolling auxiliary materials upward, and then as the roller 120 rolls, the main food, semi-finished product and rolling auxiliary materials pushed upward gradually roll downward, which is beneficial for the main food, semi-finished product and rolling auxiliary materials to roll in the rolling cavity, and is beneficial for the main food to be wrapped with the rolling auxiliary materials, and is beneficial for the semi-finished product to be more fully wrapped with the rolling auxiliary materials. At the same time, after the semi-finished product is rolled, it is easier to move toward the inlet and outlet.

[0068] The connection structure between the roller barrel 120 and the roller base 110 is as follows: A rolling ring 123, coaxially arranged with the roller barrel 120, is fixed to the outer barrel 122. There are at least two rolling rings 123, each fixed to the outer surface of the outer barrel 122 and arranged side by side along the axis of the roller barrel 120. A supporting roller assembly 111, at least two, is fixed to the roller base 110. Each supporting roller assembly 111 corresponds to a rolling ring 123, and each rolling ring 123 abuts against a corresponding supporting roller assembly 111. A transmission shaft 150, parallel to the axis of the roller barrel 120, is rotatably connected to the roller base 110. A drive motor 130 is in transmission connection with the transmission shaft 150. In this embodiment, the drive motor 130 drives the transmission shaft 150 via a chain. The transmission shaft 150 and the roller barrel 120 are connected through a belt assembly. In this embodiment, there are three rolling rings 123, which are the first rolling ring, the second rolling ring and the third rolling ring along the axial direction of the roller barrel 120; there are three support roller groups 111, and the three support roller groups 111 and the three rolling rings 123 are arranged in a one-to-one correspondence; two pulleys are provided on the transmission shaft 150, and the two pulleys are the first pulley and the second pulley, respectively, wherein the first pulley is arranged between the first rolling ring and the second rolling ring, and the second pulley is arranged between the second rolling ring and the third rolling ring, the same transmission belt is wound around the first pulley and the roller barrel 120, and the same transmission belt is wound around the second pulley and the roller barrel 120.

[0069] Each support roller assembly 111 includes a first roller and a second roller rotatably connected to the roller base 110. Within each support roller assembly 111, the axes of the first and second rollers are parallel to the axis of the roller barrel 120. The first and second rollers are symmetrically arranged about the vertical plane of the axis of the roller barrel 120. Each rolling ring 123 simultaneously abuts against the first and second rollers in the corresponding support roller assembly 111.

[0070] The delivery endpoint of the feed conveyor device is connected to the rolling chamber. Specifically, there are two feed conveyor devices: a first feed conveyor device 210 for conveying the main food and a second feed conveyor device 220 for conveying the rolling and auxiliary materials. The delivery endpoint of the first feed conveyor device 210 extends from the feed inlet into the rolling chamber to achieve the connection between the delivery endpoint of the first feed conveyor device 210 and the rolling chamber. The delivery endpoint of the second feed conveyor device 220 extends from the feed inlet and outlet into the rolling chamber to achieve the connection between the delivery endpoint of the second feed conveyor device 220 and the rolling chamber. The feed conveyor devices are used to convey the main food and the rolling and auxiliary materials into the rolling chamber.

[0071] The conveying surface of the discharge conveyor 300 is located below the inlet and outlet. In this embodiment, the discharge conveyor 300 comprises a climbing conveyor belt, with its starting point directly below the inlet and outlet. The starting point of the climbing conveyor belt is used to receive semi-finished products and rolled auxiliary materials that have not been wrapped around the main food product. The discharge conveyor 300 terminates at the end point connected to the support chain conveyor 500. The return conveyor 400 terminates at the end point connected to the inlet conveyor. In this embodiment, the support chain conveyor belt 500 is located below the conveying end point of the discharge conveying device 300. There is a height difference between the support chain conveyor belt 500 and the conveying end point of the discharge conveying device 300. The conveying end point of the support chain conveyor belt 500 is connected to the production equipment of the next production process. It should be noted that the production equipment of the next production process mentioned here is not a component of the present utility model; the conveying surface of the return material conveying device 400 is located directly below the support chain conveyor belt 500; the conveying end point of the return material conveying device 400 is located above the feed conveying device. Specifically, the conveying end point of the return material conveying device 400 is located above the second feed conveying device 220.

[0072] The semi-finished products rolled out from the inlet and outlet and the rolling materials that are not wrapped on the main food are transported by the discharge conveyor device 300 and fall onto the support chain conveyor belt 500. Subsequently, the rolling materials that fall from the surface of the semi-finished products and the rolling materials that are not wrapped on the main food coming out of the inlet and outlet pass through the support chain conveyor belt 500 and fall onto the return conveyor device 400. They are then transported to the feed conveyor device and finally transported to the rolling cavity for utilization. The utilization rate of the rolling materials is relatively high, and there is no need to waste manpower to collect them, which saves manpower.

[0073] The second feeding and conveying device 220 includes a second conveying base 221 and a second conveying belt 222 arranged on the second conveying base 221; a brush 223 and a brush motor 224 are provided on the second feeding and conveying device 220; the brush 223 includes a brush handle and multiple bristle groups fixed on the brush handle, and the multiple bristle groups are closely arranged along the length direction of the brush handle; the multiple bristle groups each include multiple bristles arranged in a ring shape with the axis of the brush handle as the center.

[0074] The brush 223 is located above the second conveyor belt 222 and is rotatably connected to the second conveying base 221. The brush 223 is arranged perpendicular to the conveying direction of the second feed conveying device 220. The brush 223 is arranged horizontally, and a first gap is formed between the brush 223 and the conveying surface of the second feed conveying device 220; the shell of the brush motor 224 is fixed to the second conveying base 221, and the output shaft of the brush motor 224 is connected to the brush handle through a gearbox.

[0075] In this embodiment, the second conveyor belt 222 includes a first section of the second conveyor belt and a second section of the second conveyor belt, each independently disposed on the second conveyor base 221. The first section of the second conveyor belt is located below the conveying end point of the return material conveying device 400, and the conveying end point of the first section of the second conveyor belt is located above the second section of the second conveyor belt. The conveying end point of the second section of the second conveyor belt extends from the inlet and outlet into the rolling cavity to achieve connection between the second feed conveying device 220 and the rolling cavity. A brush 223 and a brush motor 224 are respectively mounted on the first section of the second conveyor belt. The brush 223 and the brush motor 224 are respectively located near the conveying end point of the first section of the second conveyor belt, and the brush 223 is arranged perpendicular to the conveying direction of the first section of the second conveyor belt.

[0076] During use, the rolling material is conveyed on the second feeding and conveying device 220. When the rolling material passes through the first gap, the brush motor 224 drives the brush 223 to rotate to flatten the rolling material passing through the first gap to ensure that the rolling material can be evenly arranged on the conveying path from the position corresponding to the brush 223 on the second feeding and conveying device 220 to the conveying end point, thereby ensuring that the amount of rolling material entering the rolling cavity per unit time can remain relatively stable.

[0077] The rolling material machine also includes a grouting device 700, the grouting outlet of the grouting device 700 is connected to the rolling material chamber. In this embodiment, the grouting device 700 includes a grouting base 710, a grouting bucket 720, a feed pipe 730, a pressure pump 740 and a grouting pipe 750. The grouting base 710 is located on one side of the rolling material machine 100, and the grouting bucket 720 and the pressure pump 740 are respectively installed on the grouting base 710. One end of the feed pipe 730 is connected to the grouting bucket 720, and the other end is connected to the grouting inlet of the pressure pump 740; the grouting outlet of the pressure pump 740 is connected to one end of the grouting pipe 750, and the other end of the grouting pipe 750 extends from the feed inlet into the rolling material chamber.

[0078] By providing the grouting device 700 and performing grouting during the rolling process of the auxiliary materials and the main food, the bonding force between the auxiliary materials and the main food can be improved, so that the auxiliary materials can be better wrapped around the main food.

[0079] A scraper assembly 140 is also provided within the rolling chamber. The scraper assembly 140 includes a scraper frame 141 and a scraper blade 142. The scraper frame 141 is fixed to the rolling base 110. A long hole is defined in the scraper frame 141, perpendicular to the axis of the rolling drum 120. A bolt assembly is provided in the hole. A soft scraper blade 142 is detachably connected to the scraper frame 141 via the bolt assembly. The soft scraper blade 142 abuts against the inner wall of the octagonal drum 122. It should be noted that the soft scraper blade 142 can be a silicone scraper with a hardness range of 30 Shore A (representing a hardness value of 30 on the Shore A scale) to 70 Shore A, or a rubber scraper with a hardness range of 30 Shore A to 70 Shore A. Shore A is a unit of hardness on the Shore A scale. In this embodiment, the soft scraper blade 142 is a silicone scraper with a hardness of 55 Shore A.

[0080] After the rolling material and the grouting water are combined, they tend to accumulate and stick to the inner wall of the octagonal drum 122. By setting the soft scraper 142, during the rolling process of the rolling drum 120, the soft scraper 142 adheres to the inner wall of the octagonal drum 122 and scrapes off the rolling material and the grouting water stuck to the inner wall of the octagonal drum 122, which helps to prevent the rolling material and the grouting water from accumulating into blocks on the inner wall of the octagonal drum 122.

[0081] The present invention has been described in detail above with reference to the accompanying drawings, but the embodiments of the present invention are not limited to the above embodiments.
