Description

Technical Field

[0001] This invention relates to the field of food machinery technology, specifically to a cutting device and a food coating equipment. Background Technology

[0002] Many foods (such as mochi and glutinous rice cakes) require their surfaces to be evenly coated with flour during the production and processing process. This process can increase the texture and flavor of the food, giving it a better appearance and taste, and improving its nutritional value.

[0003] The patent with announcement number CN215381079U and patent name "a fermented dough shearing device" first uses a shearing motor to drive the cutter to rotate and cut the dough into pieces. The cut dough pieces enter the coating chamber and are coated with flour. However, after coating, the pieces of dough are messy and scattered. It is necessary to use a sorting roller and sorting box to sort the pieces of dough before they can enter the next process, resulting in low production efficiency.

[0004] Therefore, this application proposes a method of coating with flour before slicing to eliminate the material handling process and improve production efficiency. However, in the method of coating with flour before slicing, the cut edges are prone to lacking flour, which cannot meet the requirements of some products that also require flour coating at the cut edges. Therefore, this application proposes a slicing device and a food flour coating equipment that can automatically replenish flour at the cut edges. Summary of the Invention

[0005] One of the objectives of this invention is to provide a slitting device that automatically replenishes powder to the cut surfaces during the slitting process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cutting device, comprising:

[0008] Powder hopper, cutter and cutter drive assembly;

[0009] The bottom of the powder box is shaped like a truncated cone, wider at the top and narrower at the bottom, with a material inlet at the center of the cone. Below the powder box, corresponding to the cutter, are two elastic plates arranged in an inverted V-shape, with the minimum distance between the two elastic plates being less than the thickness of the cutter blade.

[0010] The blade of the cutter extends downward through the discharge port, and the cutter has discharge notches on both sides of the blade located above the two elastic plates;

[0011] The cutter drive assembly drives the cutter to move up and down. When the cutter is in the lower stop position, a material discharge channel is formed between the material discharge notch and the material discharge port. The cutter body expands the two elastic plates, and the cutting edge of the cutter cuts the material. When the cutter is in the upper stop position, the cutter body closes the material discharge port, the cutting edge of the cutter leaves the elastic plates, and the elastic plates unload the material.

[0012] Preferably, the blade of the cutter has several combs on both sides above its material feeding notch.

[0013] The second objective of this invention is to provide a food coating device that avoids powder from being blown up and improves coating efficiency.

[0014] To achieve the above objectives, the present invention adopts the following technical solution:

[0015] A food coating equipment includes the above-mentioned cutting device; and a conveyor frame and a coating box, wherein the cutting device is disposed at the end of the conveyor frame along the production line direction;

[0016] The conveyor frame includes a frame, a conveyor belt, and a rotating wheel that drives the conveyor belt to rotate in a circular motion. The rotating wheel is located at the front and rear ends of the frame and is driven to rotate by a rotating wheel drive component.

[0017] The powder coating box is located at the front end of the conveying platform. Along the material conveying direction from front to back, the front and rear side walls of the powder coating box are respectively provided with an inlet and an outlet.

[0018] A forward rotating shaft is provided in the middle of the coating box.

[0019] Preferably, the length of the forward rotating shaft is greater than the maximum width of the material being conveyed.

[0020] Preferably, a reverse rotating shaft is provided inside the powder coating box near the discharge port. Multiple baffles are evenly distributed around the center point on the peripheral wall of the reverse rotating shaft. The reverse rotating shaft is driven by a rotating shaft drive and rotates in a direction opposite to the material conveying direction.

[0021] Preferably, the height of the reverse rotating shaft is lower than the height of the forward rotating shaft.

[0022] Preferably, the top of the coating box is provided with a flip-up cover.

[0023] Preferably, the front and rear ends of the coating box are provided with material collection troughs, and the material collection troughs are provided with material conveying plates parallel to the conveyor belt; a material collection box is detachably connected to the bottom of the material collection trough.

[0024] Preferably, it also includes a storage bin, which is connected to the powder coating box body via a feeding pipe;

[0025] A feeding sensor is installed at the bottom of the coating box. When the feeding sensor detects that the weight value inside the coating box is lower than the required weight value, it triggers the feeding of the storage box.

[0026] Preferably, it also includes a pressure roller, which is disposed in front of the cutting device and spans across the top of the conveyor belt, with a gap between the lower edge of the pressure roller and the upper surface of the conveyor belt.

[0027] By adopting the above technical solution, the present invention has the following advantages compared with the prior art:

[0028] 1. The cutting device of the present invention can automatically replenish powder to the cut surface when cutting materials, so as to achieve full powder coating of the cut block-shaped materials.

[0029] 2. The traditional method of coating materials with powder involves cutting them first and then coating them with powder, which results in messy materials after coating. The materials need to be sorted before they can be packaged. Compared with the traditional method, this invention can coat the materials with powder first and then cut them with a cutting device. The resulting block materials are fully coated with powder and arranged neatly. They can be packaged without sorting, which effectively improves production efficiency. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0049] Example 1

[0050] Please refer to Figure 1 and Figure 2 As shown, this embodiment provides a cutting device, including a powder box 171, a cutter 172, and a cutter drive assembly 173.

[0051] Specifically, the cutting device 17 is used to cut elongated materials into blocks. The cutting device 17 includes a powder bin 171 for replenishing powder at the cut edges of the material. The bottom of the powder bin 171 is a truncated cone shape, wider at the top and narrower at the bottom, with a discharge port at the center of the cone. The slope of the truncated cone (preferably greater than 45°) facilitates the powder to converge towards the center of the cone, making discharge easier. The powder bin 171 has a flip-top design, allowing for timely replenishment of powder. Powder can be replenished manually or automatically by suction pump from the collection bin 122.

[0052] Below the powder box 171, two elastic plates 1711 (using metal springs) are symmetrically arranged in an inverted V-shape with the cutter 172 as the center. The minimum distance between the two elastic plates 1711 is less than the thickness of the cutter body 172.

[0053] The blade of the cutter 172 extends downward through the discharge port, and the cutter 172 has discharge notches 1721 on both sides of the blade located above the two elastic plates 1711.

[0054] The cutter drive assembly 173 is used to drive the cutter 172 to move up and down. In an optional embodiment, the cutter drive assembly 173 is an SJA screw jack.

[0055] Thus, when the cutter 172 is in the lower stop position, a material discharge channel is formed between the material discharge notch 1721 and the material discharge port. At this time, the blade of the cutter 172 expands the two elastic plates 1711, allowing the two elastic plates 1711 to store elastic potential energy. Because the blade of the cutter 172 is in close contact with the elastic plates 1711, the powder can be completely supported on the elastic plates 1711 and will not fall. When the cutting edge of the cutter 172 contacts the material, it cuts the material.

[0056] When the cutter 172 is in the upper stop position, the material discharge notch 1721 of the cutter 172 moves upward away from the material discharge port, the blade of the cutter 172 closes the material discharge port to prevent further material discharge, and the cutting edge of the cutter 172 also leaves the elastic sheet 1711 at this time. The elastic sheet 1711 restores its deformation and releases elastic potential energy, shaking the powder that fell on the elastic sheet 1711 to the cutting position of the material, thus achieving powder coating at the cutting position.

[0057] Regardless of whether the cutter 172 is in the upper or lower stop position, its material discharge notch 1721 is always above the elastic sheet 1711, so as to avoid the elastic sheet 1711 being damaged by a barb during the downward movement of the cutter body.

[0058] In this way, the long strip-shaped material can be evenly coated with powder first, and then the cutting device 17 can be used to cut it and the cut edges can be replenished with powder. The resulting block-shaped material is fully coated with powder and arranged neatly. It can be packaged without material handling, which effectively improves production efficiency.

[0059] like Figure 1 and Figure 2 As shown, in this embodiment, the blade of the cutter 172 has several comb teeth 1722 on both sides above the material drop notch 1721 to push the material during the up and down movement of the cutter 172, so that the powder is loose and easy to fall.

[0060] Example 2

[0061] Please refer to Figures 1-6 As shown, a second aspect of this embodiment also provides a food coating device, including a cutting device, a conveyor frame, and a coating box. The cutting device is the same as the one described in Embodiment 1, and is located at the end of the conveyor frame along the production line direction. The conveyor frame includes a frame, a conveyor belt, and a rotating wheel that drives the conveyor belt to rotate in a circular motion. The rotating wheel is located at the front and rear ends of the frame and is driven to rotate by a rotating wheel drive component. The coating box is located at the front end of the conveyor frame, and an inlet and an outlet are respectively provided on the front and rear side walls of the coating box along the material conveying direction from front to back. A forward rotating shaft is located in the middle of the coating box.

[0062] Specifically, one optional rotary drive 104 is a Y2-112M-4 three-phase asynchronous motor, which drives the rotary wheel 103 to rotate the conveyor belt 102 in a circular motion. The powder coating box 11 is filled with powder for coating. The inlet 111 and outlet 112 of the powder coating box 11 have dimensions adapted to the conveyed material, so that the long strip-shaped material can enter the powder coating box 11 through the inlet 111, and the powder in the powder coating box 11 is not easy to spill from the inlet 111 and outlet 112. A forward rotating shaft 113 is provided in the middle of the powder coating box 11 to support the material. The height of the powder installed in the powder coating box 11 is higher than the height of the forward rotating shaft 113. When the material is conveyed from front to back, it drives the forward rotating shaft 113 to rotate in the same direction, so that the material can pass through the powder and be evenly coated before leaving the powder coating box 11 through the outlet 112.

[0063] The long strip of material is evenly coated with powder and then conveyed from the discharge port 112 of the powder coating box 11 to the conveyor belt 102 of the conveyor frame 10. Driven by the rotary drive 104, it is conveyed along the production line to the cutting device 17 for cutting into pieces. The cutting device 17 can also replenish powder at the cut when cutting the material. The cut pieces are neatly arranged and conveyed along the production line.

[0064] In this way, by adopting the method of coating materials with powder before cutting and dividing them into blocks, the materials can be packaged immediately after cutting and dividing them into blocks. This solves the problem of the materials being messy and scattered after coating with powder, which is caused by the traditional method of cutting materials first and then coating them with powder. It also saves the process of sorting materials before packaging and effectively improves production efficiency.

[0065] It also avoids the problem of powder flying around, reducing powder waste and harm to the human body.

[0066] like Figure 5 As shown, in this embodiment, the length of the forward rotating shaft 113 is greater than the maximum width of the conveyed material.

[0067] In this embodiment, the forward rotating shaft 113 is used to support the material and rotate in the direction of material conveying so that the material passes through the powder in the powder coating box 11 and leaves the powder coating box 11 from the discharge port 112, so as to achieve uniform powder coating of the material. The length of the forward rotating shaft 113 is greater than the maximum width of the conveyed material so that the forward rotating shaft 113 can fully support the material, ensuring the stability of the material during the conveying process, and preventing it from falling off and interrupting the powder coating process, so as to ensure the normal operation of the powder coating process.

[0068] like Figures 3-6 As shown, in this embodiment, a reverse rotating shaft 114 is provided in the powder coating box 11 near the discharge port 112. Multiple baffles 1141 are evenly distributed around the center point on the peripheral wall of the reverse rotating shaft 114. The reverse rotating shaft 114 is driven by the rotating shaft drive 115 and rotates in a direction opposite to the material conveying direction.

[0069] In this embodiment, an optional rotating shaft drive 115 is a Y2-112M-4 three-phase asynchronous motor. Since the material is conveyed from front to back in the powder coating box 11, it drives the forward rotating shaft 113 to rotate in the same direction. This may cause the powder in the powder coating box 11 to accumulate near the discharge port 112 under the influence of the material and the forward rotating shaft 113. Therefore, a reverse rotating shaft 114 is set in the powder coating box 11 near the discharge port 112. Multiple baffles 1141 are evenly distributed around the center point on the peripheral wall of the reverse rotating shaft 114. The rotating shaft drive 115 drives the reverse rotating shaft 114 to rotate in the opposite direction to the material conveying direction. When the reverse rotating shaft 114 rotates, the baffles 1141 push the powder in the opposite direction to the conveying direction to avoid the powder accumulating at the discharge port 112 of the powder coating box 11, ensuring that the powder is evenly distributed in the powder coating box 11, thereby ensuring the uniformity of the powder coating.

[0070] like Figure 3 and Figure 6 As shown, in this embodiment, the height of the reverse rotating shaft 114 is lower than the height of the forward rotating shaft 113.

[0071] In this embodiment, the forward rotating shaft 113 is used to support the material and rotate with the material. The reverse rotating shaft 114 pushes the material in the opposite direction to the material conveying direction under the drive of the rotating shaft drive 115. The height of the reverse rotating shaft 114 is lower than the height of the forward rotating shaft 113. Therefore, the reverse rotating shaft 114 does not contact the material during the material conveying process in the powder coating box 11 and will not interfere with the material conveying, so as to ensure the normal conveying of the material when it is powder coated.

[0072] like Figures 3-6 As shown, in this embodiment, the top of the powder coating box 11 is provided with a flip-up cover plate 116.

[0073] Specifically, when the food coating equipment is in operation, the cover plate 116 is closed to further prevent dust from being emitted from the powder and to prevent contaminants from falling into the coating box 11 during operation, which would affect the coating quality and ensure that the powder used for coating is clean and hygienic. After the work is completed, the cover plate 116 can be opened to clean the coating box 11.

[0074] like Figure 3 and Figure 4 As shown, in this embodiment, both the front and rear ends of the powder coating box 11 are provided with a material collection trough 12, and a material conveying plate 121 parallel to the conveyor belt 102 is provided in the material collection trough 12; a material collection box 122 is detachably connected to the bottom of the material collection trough 12.

[0075] In this embodiment, to avoid the possibility of powder leakage during material transport within the powder-coating body, a collection trough 12 is provided at both the front and rear ends of the powder-coating box 11. The material passes through the powder in the powder-coating box 11 and is evenly coated with powder. When it is transported from the discharge port 112 to the conveyor belt 102 on the conveyor platform 10, it is transported to the conveyor belt 102 via the conveyor plate 121 parallel to the conveyor belt 102 in the collection trough 12. Excess powder falls into the opening between the collection trough 12 and the collection box 122 as it passes through the conveyor plate 121. The powder falls into the collection box 122 for collection. The collection box 122 and the collection trough 12 are detachably connected. After the powder in the collection box 122 is full, the collection box 122 can be disassembled and the powder can be recycled for reuse, realizing recycling to save powder and avoid powder waste.

[0076] like Figure 3 and Figure 4 As shown, this embodiment also includes a storage bin 13, which is connected to the coating box 11 via a feeding pipe 14. A feeding sensor 15 is provided at the bottom of the coating box 11. When the feeding sensor 15 detects that the weight value inside the coating box 11 is lower than the required weight value, it triggers the storage bin 13 to feed material. An optional feeding sensor 15 is a CLF-H7 load cell.

[0077] Specifically, the storage bin 13 is used to store powder for coating, and the powder is added to the coating box 11 through the feeding pipe 14. The feeding sensor 15 is used to detect the weight of the powder in the coating box 11. When the weight of the powder in the coating box 11 is lower than the preset value, the storage bin 13 is driven to run and feed the powder into the coating box 11, so as to ensure that the powder in the coating box 11 can meet the requirements of continuously coating the material and ensuring uniform coating.

[0078] like Figure 3 and Figure 4 As shown, this embodiment also includes a pressure roller 16, which is disposed in front of the cutting device 17. The pressure roller 16 is mounted across the top of the conveyor belt 102, and there is a gap between the lower edge of the pressure roller 16 and the upper end face of the conveyor belt 102.

[0079] Specifically, after passing through the powder coating box 11, the material is evenly coated with powder. When conveyed on the conveyor belt 102, it passes through the gap below the pressure roller 16. The pressure roller 16 contacts the surface of the material and rotates in the direction of material transport to prevent the powder-coated material from slipping on the conveyor belt and causing conveying difficulties. At least one pressure roller 16 is provided, and its number and height can be set according to actual production needs.

[0080] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
