Description

Technical Field

[0001] This invention relates to the technical field of food processing, and in particular to a coating mechanism for spherical food processing surfaces. Background Technology

[0002] In the food processing industry, spherical foods such as meatballs, fish balls, and fried ice cream often require a coating process during production to achieve multiple purposes, including improving taste, locking in internal moisture, giving them a golden and crispy appearance, and allowing seasonings to adhere.

[0003] Currently, the traditional patina application methods in the industry mainly rely on manual application or the use of "sprinkling" equipment. Manual operation is not only inefficient and difficult to unify hygiene standards, but also makes it difficult to ensure the uniformity of the patina. Common automated sprinkling equipment usually pours the slurry from top to bottom onto the surface of the horizontally conveyed food. Since spherical foods have a three-dimensional curved surface, this method is very likely to cause uneven slurry adhesion, and the sides and depressions of the food are difficult to be effectively covered by the slurry, resulting in a large number of patina blind spots. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a spherical food processing surface coating mechanism, the specific technical solution of which is as follows:

[0005] The present invention provides a spherical food processing surface coating mechanism, comprising a conveying unit for horizontally conveying materials and a spraying unit for spraying slurry onto the surface of the materials on the conveying unit;

[0006] The conveying unit includes two conveying chains arranged opposite each other, two side plates arranged opposite each other, two power sprockets that cooperate with each of the conveying chains, and several support columns arranged between the two conveying chains and connected to the conveying chains. The material is placed between two adjacent support columns, and each support column is provided with a gear body at both ends.

[0007] The two side plates correspond to the two conveyor chains. The side plates are provided with teeth that cooperate with the gear body. The gear body is inclined relative to the axis of the support column. The inclination directions of adjacent gear bodies are opposite. The movement trajectory of the gear body is a horizontal capsule shape.

[0008] Furthermore, the gear body includes a limiting ring and a limiting disk located on both sides of the side plate and parallel to each other. A plurality of locking pins are provided between the limiting ring and the limiting disk. The plurality of locking pins are distributed around the circumference of the support pin. The locking pins are used in conjunction with the teeth on the side plate.

[0009] Furthermore, the gear body also includes a support shaft coaxially connected to the end of the support column. Two mounting platforms are arranged opposite each other on the outer wall of the support shaft. An adjusting column is rotatably arranged on each mounting platform. The tilt angle of the limiting ring can be adjusted by the mounting platform and the adjusting column.

[0010] A latching plate is slidably provided on the adjusting column. The latching plate and the mounting platform are engaged with each other through several protrusions and several slots. The latching plate and the limiting ring are connected by a spring.

[0011] The plurality of locking posts are parallel to each other, and the two ends of the locking posts are respectively rotatably connected to the limiting ring and the limiting disk.

[0012] Furthermore, the outer wall shape of the locking post is set to be an arc along its own axis.

[0013] Furthermore, a pin is slidably inserted in the middle of the limiting plate and is coaxially arranged with the support shaft. One end of the pin is connected to the limiting plate through a spring, and the other end of the pin is slidably inserted into the support shaft.

[0014] The limiting plate has several openings. The end of the locking pin away from the limiting ring is provided with a column. The column passes through the opening. A sliding sleeve is slidably fitted on the outer wall of the column. The sliding sleeve is rotatably connected to the inner wall of the opening through a side shaft.

[0015] Furthermore, each of the two side wall edges of the side plate is provided with a guide slope that works in conjunction with the limiting ring and the limiting disc.

[0016] Furthermore, the outer wall of the support column is provided with rubber spiral patterns, and the spiral directions of the rubber spiral patterns on two adjacent support columns are opposite.

[0017] Furthermore, one of the two adjacent support columns has two circular grooves on its outer wall, and the other support column has two baffles slidably fitted on its outer wall, with portions of the baffles located within the circular grooves and sliding relative to each other.

[0018] Furthermore, a vertical plate is provided on the support shaft, and the support shaft slides on the vertical plate. A plurality of sliding columns and connecting arms are provided on the vertical plate, and the connecting arms are connected to the conveyor chain.

[0019] The patina-forming mechanism also includes two side rings corresponding to the two side plates, and the side walls of the side rings are provided with a number of guide grooves that cooperate with each of the sliding columns.

[0020] The beneficial effects of this invention are as follows:

[0021] By utilizing the rotational motion of two adjacent support columns during movement, the object can be tumbled. This allows any position of the object in the circumferential direction to face the spray unit. Combined with the relative movement of the two adjacent support columns along their own axes, the object's lateral position during tumbling can be shifted, moving it onto the object's tumbling trajectory. Thus, the spray unit performs a comprehensive coating process on the object, improving the uniformity and coverage of the coating on the object's surface and avoiding blind spots.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0036] like Figures 1 to 8 As shown, a spherical food processing surface coating mechanism of the present invention includes a conveying unit 1 for horizontally conveying materials and a spraying unit 2 for spraying slurry onto the surface of the materials on the conveying unit 1.

[0037] The conveying unit 1 includes two conveying chains 3 arranged opposite to each other, two side plates 7 arranged opposite to each other, two power sprockets 4 that cooperate with each conveying chain 3, and several support columns 5 arranged between the two conveying chains 3 and connected to the conveying chains 3. The material is placed between two adjacent support columns 5, and gear bodies 6 are provided at both ends of the support column 5.

[0038] The two side plates 7 correspond to the two conveyor chains 3. The side plates 7 are provided with teeth that cooperate with the gear body 6. The gear body 6 is inclined relative to the axis of the support column 5. The inclination directions of the two adjacent gear bodies 6 are opposite. The movement trajectory of the gear body 6 is a horizontal capsule shape.

[0039] In this invention, the conveying unit 1 horizontally conveys food materials, and the spraying unit 2 is located above the conveying unit 1. When the items are conveyed to the area below the spraying unit 2, the spraying unit 2 sprays slurry downwards, causing the slurry to adhere to the surface of the items and achieve the purpose of coating. The spraying unit 2 can be composed of several arranged material pipes, each of which is equipped with several nozzles for spraying slurry outwards. The nozzles are flat, which facilitates the formation of a multi-layered material curtain along the path of the items, avoiding blind spots in slurry coverage. Furthermore, the tilt angle of the nozzles can be adjusted along the arrangement direction of the material pipes. The nozzles on each material pipe can be gradually increased, or they can be tilted along the width of the conveying unit 1 at different angles, so that the slurry can be sprayed in different directions to cover the surface of the item. A support 31 can be set on the outside of the spraying unit 2 to support the spraying unit 2. In order to facilitate the recovery of excess slurry on the surface of the item and on the conveying unit 1, an air pipe 33 can be added inside the support 31. The air pipe 33 is densely covered with air holes. The air is sprayed outward through the air holes, and the air can form an air knife to blow away the excess slurry on the item and the conveying unit 1, which facilitates the recovery of the slurry.

[0040] A housing 30 is added to the outside of the conveying unit 1 to facilitate support of the conveying unit 1. A bracket 31 can be installed on the housing 30. The housing 30 stores slurry. A conveying pump 32 can be installed on the outer wall of the housing 30. The input end of the conveying pump 32 is connected to the housing 30, and the output end of the conveying pump 32 is connected to each material pipe. In this way, the slurry in the housing 30 can be introduced into the material pipe through the conveying pump 32. The excess slurry sprayed from the nozzle drips back into the housing 30, thereby realizing the recycling and reuse of the slurry.

[0041] Both the conveyor chain 3 and the side plate 7 are horizontally capsule-shaped, and several support columns 5 are also arranged in a capsule shape. The power sprocket 4 and the conveyor chain 3 provide power for the rotation of the support columns 5. The support columns 5 can drive the gear body 6 to move synchronously. The gear body 6 meshes with the teeth on the side plate 7 and rolls on the side plate 7, thereby causing the gear body 6 to drive the support columns 5 to roll. The support columns 5 rotate on their own axis during the rotational motion. The rotation directions of two adjacent support columns 5 are opposite. When an item is placed between two adjacent support columns 5, one support column 5 provides an upward pushing force to the item, and the other support column 5 provides a downward pushing force to the item, thereby causing the item to tumble between the two support columns 5. Any position of the item in the circumferential direction can face the spray unit 2; because the gear body 6 is inclined... Because the gear body 6 is inclined, when it rolls on the side plate 7, along the axis of the support column 5, the gear body 6 will drive the support column 5 to reciprocate. The gear bodies 6 on the two support columns 5 are inclined in opposite directions, so along the axis of the support column 5, the movement directions of the two adjacent support columns 5 are opposite. The two support columns 5 can drive the item to rotate around the vertical axis where its center point is located. That is, when the item rolls, the areas on both sides of its rolling axis cannot move to the top of the item, so it cannot be coated. However, by using the relative movement of the two support columns 5, the positions of the areas on both sides of the item can be transferred. In this way, by using the multi-directional driving movement of the item, any position on the item can face the spray unit 2, so that the spray unit 2 can perform a full coating operation on the item.

[0042] By utilizing the rotational motion of two adjacent support columns 5 during movement, the object can be driven to tumble. In this way, any position of the object in the circumferential direction can face the spray unit 2. Combined with the relative movement of the two adjacent support columns 5 along their own axes, the lateral position of the object during tumbling can be shifted, moving the position to the tumbling trajectory of the object. Thus, the spray unit 2 is used to perform a comprehensive coating operation on the object, improving the uniformity and comprehensiveness of the coating on the surface of the object and avoiding blind spots.

[0043] Furthermore, the gear body 6 includes a limiting ring 8 and a limiting disk 9 located on both sides of the side plate 7 and parallel to each other. A plurality of locking pins 10 are provided between the limiting ring 8 and the limiting disk 9. The plurality of locking pins 10 are distributed around the circumference of the support pin 5 and are used in conjunction with the teeth on the side plate 7.

[0044] The locking pins 10 between the limiting ring 8 and the limiting disk 9 can be used to cooperate with the tooth groove area between two adjacent teeth on the side plate 7. That is, by continuously meshing the locking pins 10 with the tooth grooves on the side plate 7, the rolling effect of the gear body 6 and the support column 5 can be achieved. The limiting ring 8 and the limiting disk 9 set on both sides of the side plate 7 can be used to limit the relative position of the gear body 6 and the side plate 7, so that the gear body 6 and the side plate 7 always remain in a meshing state. Furthermore, due to the inclined setting of the limiting ring 8 and the limiting disk 9, the gear body 6 and the support column 5 can reciprocate along the axis of the support column 5 with the help of the counter-thrust of the side plate 7.

[0045] Furthermore, the gear body 6 also includes a support shaft 11 coaxially connected to the end of the support column 5. Two mounting platforms 12 are arranged opposite each other on the outer wall of the support shaft 11. An adjustment column 13 is rotatably arranged on each mounting platform 12. The tilt angle of the limiting ring 8 can be adjusted by the mounting platform 12 and the adjustment column 13.

[0046] A locking plate 14 is slidably mounted on the adjusting column 13. The locking plate 14 and the mounting platform 12 are engaged with each other by several protrusions and several slots. The locking plate 14 and the limiting ring 8 are connected by a spring 15.

[0047] Several locking posts 10 are parallel to each other, and the two ends of the locking posts 10 are rotatably connected to the limiting ring 8 and the limiting disk 9, respectively.

[0048] The inner wall of the limiting ring 8 is fixedly connected to the adjusting column 13. Therefore, with the help of the mounting platform 12 and the adjusting column 13, the limiting ring 8 can tilt on the support shaft 11, thereby adjusting the tilt angle of the limiting ring 8 and facilitating the adjustment of the amplitude of the support column 5 reciprocating along its own axis. The outer wall of the adjusting column 13 is provided with a groove along its axis, and the buckle 14 is provided with a sliding edge that cooperates with the groove. In this way, the buckle 14 can slide on the adjusting column 13, and the buckle 14 will rotate synchronously with the adjusting column 13. The protrusion and the slot between the buckle 14 and the mounting platform 12 can serve as a structure for their mutual locking. This can prevent the mounting platform 12 and the buckle 14 from rotating relative to each other. The spring 15 can provide elastic thrust for the buckle 14. When it is necessary to adjust the tilt angle of the limiting ring 8, push the buckle 14 away from the mounting platform 12 to separate the protrusion and the slot, and then rotate the buckle 14.

[0049] Since the limiting ring 8 and the limiting disk 9 are connected by several parallel locking pins 10, when the limiting ring 8 tilts, the limiting disk 9 tilts synchronously, and the locking pins 10 remain horizontal. When the limiting ring 8 tilts, the projection of the shape formed by the locking pins 10 on the vertical plane will change, that is, the shape formed by the locking pins 10 can switch between ellipse and circle. Since the locking pins 10 need to cooperate with the toothed grooves on the side plate 7, the change in the shape formed by the locking pins 10 will cause some locking pins 10 to be unable to mesh with the toothed grooves. Here, the depth of the toothed grooves can be increased to ensure that the locking pins 10 can always move into the toothed grooves and mesh with each other.

[0050] Furthermore, the outer wall shape of the locking post 10 is set to be an arc along its own axis.

[0051] If the locking post 10 is cylindrical, then when the locking post 10 moves to a position close to the side plate 7, the change in the tilt angle of the limiting ring 8 will cause unequal distances between the locking post 10 and the axis of the support post 5. In this case, the locking post 10 is at risk of disengaging from the tooth groove. To avoid this phenomenon and ensure that the locking post 10 and the tooth groove can mesh with each other, the outer wall shape of the locking post 10 can be set to an arc shape. Specifically, for example... Figure 8 As shown, the intersection of the plane containing the axis of the locking pin 10 and the outer wall of the locking pin 10 is an arc. The center of the arc intersection line on the locking pin 10 that is farthest from the axis of the support pin 5 coincides with the center point between the limiting ring 8 and the limiting disk 9. In this way, when the limiting ring 8 and the limiting disk 9 tilt, the locking pin 10 will always be able to mesh with the tooth groove.

[0052] Furthermore, a pin 16 coaxially arranged with the support shaft 11 is slidably inserted in the middle of the limiting disk 9. One end of the pin 16 is connected to the limiting disk 9 through a spring 17, and the other end of the pin 16 is slidably inserted into the support shaft 11.

[0053] The limiting plate 9 has several openings 18. The end of the locking post 10 away from the limiting ring 8 is provided with a column 19. The column 19 passes through the opening 18. A sliding sleeve 20 is slidably sleeved on the outer wall of the column 19. The sliding sleeve 20 is rotatably connected to the inner wall of the opening 18 through a side shaft 21.

[0054] The elastic thrust provided by spring 17 to the limiting plate 9 allows the limiting plate 9 and the limiting ring 8 to clamp the side plate 7, thereby keeping the gear body 6 in a working state with the side plate 7. When the limiting ring 8 and the limiting plate 9 contact the side plate 7 at different positions, the gap width between the limiting ring 8 and the limiting plate 9 is different due to the different inclination directions of the gear body 6. The sliding arrangement of the limiting plate 9 on the insert post 16 and the setting of spring 17 allow the gap between the limiting ring 8 and the limiting plate 9 to change, as long as it can always clamp the side plate 7.

[0055] Since the tilt angles of the limiting ring 8 and the limiting plate 9 are adjustable, the limiting plate 9 and the insert post 16 need to be connected by a ball installed in the middle of the limiting plate 9. That is, the insert post 16 slides through the ball in the middle of the limiting plate 9, and the limiting plate 9 can rotate on the ball. When the distance between the limiting ring 8 and the limiting plate 9 changes, the limiting plate 9 will drive the sliding sleeve 20 to slide on the column 19 through the side shaft 21. When the tilt angle of the limiting plate 9 changes, the limiting plate 9 and the locking post 10 rotate relative to each other, and the side shaft 21 and the inner wall of the through 18 rotate relative to each other. The relative sliding of the column 19 and the sliding sleeve 20 allows the limiting plate 9 to slide on the insert post 16.

[0056] Furthermore, guide ramps 22 are provided at the edges of both sides of the side plate 7 to cooperate with the limiting ring 8 and the limiting disc 9.

[0057] Since the gear body 6 clamps the edge of the side plate 7 through the limiting ring 8 and the limiting disk 9, and the gear body 6 is inclined, in order to avoid the edge of the limiting ring 8 and the edge of the limiting disk 9 cutting the edge of the side plate 7 when the gear body 6 rotates, a guide slope 22 can be set on the side plate 7. The guide slope 22 guides the limiting ring 8 and the limiting disk 9, so that the limiting ring 8 and the limiting disk 9 can always be located on both sides of the side plate 7 and restrict the side plate 7.

[0058] Furthermore, the outer wall of the support column 5 is provided with rubber spiral patterns 23, and the spiral directions of the rubber spiral patterns 23 on two adjacent support columns 5 are opposite.

[0059] When the support column 5 rotates, the rubber spiral pattern 23 can provide lateral thrust to the items between the two adjacent support columns 5. The opposite spiral direction of the two adjacent rubber spiral patterns 23 can help the items rotate on the vertical axis where their center point is located. Combined with the relative motion mode of the two adjacent support columns 5, the position adjustment range of the two sides of the support column 5 when it rolls is increased.

[0060] Furthermore, two circular grooves 24 are provided on the outer wall of one of the two adjacent support columns 5, and two baffles 25 are slidably fitted on the outer wall of the other support column 5, with a portion of the baffles 25 located in the circular grooves 24 and sliding relative to each other.

[0061] The area between the two baffles 25 and the two circular grooves 24 is the item holding area. The baffles 25 can block the items in the holding area. Due to the relative movement of the two adjacent support columns 5, the circular groove 24 on one support column 5 will push the baffle 25 on the other support column 5 to slide on the support column 5, so that the two baffles 25 can always cover the area between the two support columns 5 and allow the two support columns 5 to move relative to each other.

[0062] Furthermore, a vertical plate 26 is provided on the support shaft 11, and the support shaft 11 slides on the vertical plate 26. A plurality of sliding columns 27 and connecting arms 28 are provided on the vertical plate 26, and the connecting arms 28 are connected to the conveyor chain 3.

[0063] The patina mechanism also includes two side rings 29 corresponding to the two side plates 7, and the side walls of the side rings 29 are provided with several guide grooves that cooperate with each sliding column 27.

[0064] The conveyor chain 3 can drive the support column 5 to rotate through the connecting arm 28 and the vertical plate 26. The reciprocating motion of the support column 5 will cause the support shaft 11 to slide relative to the vertical plate 26. Several sliding columns 27, side rings 29 and several guide grooves opened on the side rings 29 can guide the vertical plate 26 and the support column 5, so that the support column 5 can rotate smoothly.

[0065] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
