Description

A new type of leather stacking machine Technical Field

[0001] This utility model relates to the field of food processing technology, specifically to a novel skin-stacking machine. Background Technology

[0002] In the processing of pasta products, traditional manual operation is not only inefficient, but also makes it difficult to guarantee product quality and hygiene standards. Therefore, the research and development of various automated mechanical equipment has become a research hotspot in this field. Currently, the most common equipment on the market is the fully automatic dough pressing and stacking machine.

[0003] Existing automatic dough pressing and stacking machines use a transmission chain as the power transmission method. This causes the machine oil required for chain lubrication to easily evaporate and overflow during long-term operation, adhering to the surface of the dough and affecting the safety and quality of the food. At the same time, due to the rigidity of the chain itself, it cannot accurately control the position of the tray, resulting in uneven stacking of dough and affecting the smooth progress of subsequent processing steps.

[0004] Therefore, it is necessary to invent a new type of leather-folding machine to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a new type of dough stacking machine to solve the problems in the technology where the machine oil required for chain lubrication easily evaporates and overflows, adhering to the surface of the dough, affecting the safety and quality of food. At the same time, due to the rigidity limitation of the chain itself, it is impossible to accurately control the position of the tray, resulting in uneven stacking of dough, which affects the smooth progress of subsequent processing steps.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel leather stacking machine, comprising a first positioning bracket, a first conveyor belt disposed on the inner side of the first positioning bracket, a conveying mechanism disposed on the upper side of the first positioning bracket, the conveying mechanism comprising a second positioning bracket, a second conveyor belt, a third positioning bracket, a third conveyor belt, a powder spreader and a brush, a receiving plate disposed on the upper side of the first conveyor belt, multiple sets of snap-fit ​​grooves uniformly formed on the surface of the first conveyor belt, and multiple sets of snap-fit ​​blocks fixedly connected to the lower surface of the receiving plate, the snap-fit ​​blocks snapping into the inside of the snap-fit ​​grooves.

[0007] By adopting the above technical solution, the first conveyor belt is driven by a forward and reverse motor. The forward and reverse motor works with the transmission roller to drive the first conveyor belt to rotate left and right in a circular motion, thereby driving the receiving plate to slide back and forth in a circular motion to fold the dough. The stability of the receiving plate during movement is improved by the cooperation of the locking block and the locking groove. The second and third conveyor belts are driven by ordinary motors. The motor works with the transmission roller to drive the second conveyor belt to rotate counterclockwise and the third conveyor belt to rotate clockwise.

[0008] Optionally, the second positioning bracket is disposed on the upper side of the first positioning bracket, the second conveyor belt is disposed on the inner side of the second positioning bracket, the third positioning bracket is disposed on the upper side of the second positioning bracket, and the third conveyor belt is disposed on the inner side of the third positioning bracket.

[0009] Optionally, a powder spreader is fixedly connected to the upper side of both the second and third positioning brackets. A brush is fixedly connected to the right side of the upper powder spreader and a brush is fixedly connected to the left side of the lower powder spreader.

[0010] By adopting the above technical solution, after the dough is pressed into a sheet by the dough press machine, the third conveyor belt transports the sheet to the right. The sheet falls from the right end of the third conveyor belt and overlaps the surface of the second conveyor belt. The second conveyor belt flips it over and transports it to the left. During the transport process, the upper and lower powder sprinklers sprinkle flour on both sides of the sheet and spread the flour evenly with a brush.

[0011] Optionally, a first fixed frame is fixedly connected to the upper surface of the second positioning bracket at the position on the right side of the powder spreader, and a first support roller is rotatably connected to the inner side of the first fixed frame. A second fixed frame is fixedly connected to the left end of the lower surface of the second positioning bracket, and two sets of second support rollers are rotatably connected to the inner side of the second fixed frame.

[0012] By adopting the above technical solution, the first support roller guides the dough hanging down from the right end of the third conveyor belt, and the two sets of second support rollers guide the dough hanging down from the left end of the second conveyor belt.

[0013] Optionally, the first positioning bracket is provided with transmission rods on both the front and rear sides. Multiple sets of fixing rods are fixedly connected to the surface of the two sets of transmission rods that are close to each other. A positioning roller is rotatably connected to the end of the fixing rod that is away from the transmission rod. Multiple sets of positioning plates are fixedly connected to the lower surface of both sets of transmission rods. Multiple sets of positioning rods are fixedly connected to the front and rear surfaces of the first positioning bracket. The lower end of the positioning plate is slidably connected to the positioning rod.

[0014] By adopting the above technical solution, the transmission rod slides in opposite directions on the upper side of the first positioning bracket, driving the positioning rollers on the front and rear sides to move inward and position the front and rear sides of the receiving plate, preventing the receiving plate from deviating during the sliding process, improving the neatness of the folding of the dough, and can be used for receiving plates of different widths, improving the ease of use. The positioning rod is used to improve the stability of the transmission rod during the sliding process.

[0015] Optionally, an equipment box is fixedly connected to the lower surface of the first positioning bracket, and two sets of limiting grooves are opened on the upper surface of the equipment box. A limiting plate is slidably connected inside the two sets of limiting grooves, and the upper end of the limiting plate is fixedly connected to the transmission rod.

[0016] By adopting the above technical solution, the limiting plate slides inside the limiting groove.

[0017] Optionally, a transmission gear is rotatably connected to the center of the equipment box. An electric motor is fixedly installed at the lower end of the transmission gear. The output end of the electric motor is coaxially and fixedly connected to the transmission gear. Transmission racks are meshed on both the left and right sides of the transmission gear. A connecting rod is fixedly connected to the rear end of the left transmission rack and the front end of the right transmission rack. The connecting rod is fixedly connected to the lower end of the limiting plate.

[0018] By adopting the above technical solution, the electric motor can rotate in both directions, driving the transmission gear to rotate clockwise or counterclockwise. When the transmission gear rotates counterclockwise, it drives the left transmission rack to slide forward and the right transmission rack to slide backward, thereby driving the two sets of limit plates to slide towards each other and then driving the two sets of transmission rods on the upper side to slide towards each other. Conversely, when the transmission gear rotates clockwise, it drives the two sets of transmission rods to slide away from each other.

[0019] Optionally, guide rods are fixedly connected to both the left and right sides inside the equipment box, and guide grooves are opened on the surface of the two sets of guide rods that are close to each other. A positioning strip is fixedly connected to the side of the transmission rack, and the positioning strip is slidably connected to the guide groove.

[0020] By adopting the above technical solution, during the sliding process of the transmission rack, the positioning strip is driven to slide inside the guide groove, thereby improving the stability of the transmission rack sliding.

[0021] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0022] 1. This utility model uses a motor-driven conveyor belt to transport the dough, effectively avoiding foreign matter from the chain from contaminating the dough surface and improving food safety. At the same time, the use of locking blocks and locking grooves to limit the position of the receiving plate improves the stability of the receiving plate during movement, avoids displacement during reciprocating sliding, and improves the neatness of dough folding.

[0023] 2. This utility model utilizes an electric motor to drive the transmission gear to rotate counterclockwise. Through two sets of transmission racks, it drives the front and rear limit plates to slide and move closer together, which in turn drives the two upper transmission rods to slide and move closer together. This causes the positioning rollers on the front and rear sides to move inward, positioning the front and rear sides of the receiving plate. This prevents the receiving plate from deviating during the sliding process, further improving the neatness of the folded dough, facilitating subsequent processing, and is applicable to receiving plates of different widths, thus improving ease of use.

[0033] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0034] This utility model provides a novel leather stacking machine as shown in Figures 1 to 4, including a first positioning bracket 1, a first conveyor belt 11 disposed on the inner side of the first positioning bracket 1, and a conveying mechanism disposed on the upper side of the first positioning bracket 1. The conveying mechanism includes a second positioning bracket 4, a second conveyor belt 41, a third positioning bracket 46, a third conveyor belt 47, a powder spreader 48, and a brush 49. A receiving plate 13 is disposed on the upper side of the first conveyor belt 11, and multiple sets of snap-fit ​​grooves 12 are evenly opened on the surface of the first conveyor belt 11. Multiple sets of snap-fit ​​blocks 14 are fixedly connected to the lower surface of the receiving plate 13, and the snap-fit ​​blocks 14 snap into the inside of the snap-fit ​​grooves 12. The second positioning bracket 4 is disposed on the upper side of the first positioning bracket 1, and the second conveyor belt 41 is disposed on the upper side of the first positioning bracket 1. Inside the second positioning bracket 4, the third positioning bracket 46 is located above the second positioning bracket 4, and the third conveyor belt 47 is located inside the third positioning bracket 46. A powder spreader 48 is fixedly connected to the upper side of both the second positioning bracket 4 and the third positioning bracket 46. A brush 49 is fixedly connected to the right side of the upper powder spreader 48 and to the left side of the lower powder spreader 48. A first fixing frame 42 is fixedly connected to the upper surface of the second positioning bracket 4 at the position to the right of the powder spreader 48. A first support roller 43 is rotatably connected to the inner side of the first fixing frame 42. A second fixing frame 44 is fixedly connected to the left end of the lower surface of the second positioning bracket 4. Two sets of second support rollers 45 are rotatably connected to the inner side of the second fixing frame 44.

[0035] In the process of use, the receiving plate 13 is first placed on the surface of the first conveyor belt 11, and the snap-fit ​​block 14 is snapped into the inside of the snap-fit ​​groove 12 to fix the position of the receiving plate 13. Next, the equipment parameters are adjusted on the surface of the control panel to keep the first conveyor belt 11, the second conveyor belt 41 and the third conveyor belt 47 at the same speed, and the position of the receiving plate 13 is limited by the limit sensor.

[0036] In addition, a dough press is installed at the left end of the third positioning bracket 46. The dough press presses the kneaded dough into a sheet and overlaps the end of the sheet with the surface of the third conveyor belt 47. The third conveyor belt 47 rotates clockwise and conveys the pressed sheet to the right. When the sheet passes under the upper powder sprinkler 48, the upper powder sprinkler 48 sprays flour onto the top of the sheet and spreads the flour evenly on the surface of the sheet with a brush 49. As the length of the sheet increases, the lower end of the sheet overlaps the right end of the second conveyor belt 41. At this time, the second conveyor belt 41 rotates counterclockwise and conveys the sheet to the left. The sheet is in a flipped state with the flour-sprinkled side facing up. During the conveying process, the lower powder sprinkler 48 sprays flour onto the un-powdered side of the sheet and spreads it evenly with a brush 49 on the side.

[0037] Simultaneously, as the second conveyor belt 41 moves the dough to the left, the first support roller 43 supports and positions the dough at the right end of the second conveyor belt 41. When the dough reaches the leftmost end of the second conveyor belt 41, it passes through the inside of the two sets of second support rollers 45, which position the dough. Both the first and second support rollers 43 and 45 rotate with the movement of the dough to maintain its smoothness. At this time, the right end of the receiving plate 13 is adjusted to the first... The second conveyor belt 41 is positioned directly below the left end of the second conveyor belt 41, with the lower end of the dough overlapping the right end of the receiving plate 13. At this time, the first conveyor belt 11 drives the receiving plate 13 to slide to the right at a uniform speed, laying the dough flat on the surface of the receiving plate 13. When the left end of the receiving plate 13 moves to directly below the left end of the second conveyor belt 41, the forward and reverse motor drives the first conveyor belt 11 to reverse, sliding the receiving plate 13 to the left to fold the dough and lay it flat on the surface of the lower side dough. This process is repeated to fold the dough.

[0038] Referring to Figures 3, 5 to 7, transmission rods 3 are provided on both the front and rear sides of the first positioning bracket 1. Multiple sets of fixing rods 31 are fixedly connected to the surface of the two sets of transmission rods 3 that are close to each other. Positioning rollers 32 are rotatably connected to the end of each fixing rod 31 that is away from the transmission rod 3. Multiple sets of positioning plates 33 are fixedly connected to the lower surface of both sets of transmission rods 3. Multiple sets of positioning rods 15 are fixedly connected to both the front and rear surfaces of the first positioning bracket 1. The lower end of the positioning plate 33 is slidably connected to the positioning rod 15. An equipment box 2 is fixedly connected to the lower surface of the first positioning bracket 1. Two sets of limiting grooves 21 are provided on the upper surface of the equipment box 2. Limiting plates 22 are slidably connected inside the two sets of limiting grooves 21. The upper end of the limiting plate 22 is connected to the transmission rod 3. A transmission gear 23 is rotatably connected at the center of the equipment box 2. An electric motor 29 is fixedly installed at the lower end of the transmission gear 23. The output end of the electric motor 29 is coaxially and fixedly connected to the transmission gear 23. Transmission racks 24 are meshed on both the left and right sides of the transmission gear 23. A connecting rod 26 is fixedly connected to the rear end of the left transmission rack 24 and the front end of the right transmission rack 24. The connecting rod 26 is fixedly connected to the lower end of the limiting plate 22. Guide rods 27 are fixedly connected to both the left and right sides of the equipment box 2. Guide grooves 28 are opened on the surface of the two sets of guide rods 27 that are close to each other. A positioning strip 25 is fixedly connected to the side of the transmission rack 24. The positioning strip 25 is slidably connected to the guide groove 28.

[0039] Specifically, after the receiving plate 13 is placed on the surface of the first conveyor belt 11, the electric motor 29 is started. The electric motor 29 drives the transmission gear 23 to rotate counterclockwise. At this time, the transmission gear 23 drives the left transmission rack 24 to slide forward and the right transmission rack 24 to slide backward, thereby driving the two sets of front and rear limit plates 22 to slide towards each other, and then driving the two sets of upper transmission rods 3 to slide towards each other, moving the positioning rollers 32 on both sides inward synchronously, positioning the receiving plate 13 at the center of the first conveyor belt 11. During the movement of the receiving plate 13, the position of the receiving plate 13 is limited to maintain the stability of the movement of the receiving plate 13, avoid the plate from deviating during the movement, and further improve the receiving accuracy.

[0040] The working principle of this utility model is as follows: By using a motor-driven conveyor belt to transport the dough, foreign objects generated by the chain can be effectively avoided from contaminating the surface of the dough, thus improving food safety. At the same time, the locking block 14 and locking groove 12 cooperate to limit the position of the receiving plate 13, improving the stability of the receiving plate 13 during movement and preventing deviation during reciprocating sliding, thereby improving the neatness of the dough folding. Simultaneously, the electric motor 29, transmission gear 23, and two sets of transmission racks 24 work together to drive the two sets of limiting plates 22 to slide towards each other, which in turn drives the two sets of transmission rods 3 on the upper side to slide towards each other, causing the positioning rollers 32 on the front and rear sides to move inward, positioning the receiving plate 13 in the middle of the first conveyor belt 11, and further improving the stability of the receiving plate 13 during movement, preventing the receiving plate 13 from deviating during sliding, further improving the neatness of the dough folding, and facilitating subsequent processing.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
