Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, and in particular to an automatic surface coating mechanism for Sachima (a type of Chinese pastry). Background Technology

[0002] Sachima, a type of puffed and fried pastry, is typically topped with sesame seeds, chopped nuts, powdered sugar, and other toppings after preparation to enhance its flavor and appearance. Traditionally, this topping process relies on manual labor or relatively simple mechanical equipment.

[0003] On automated production lines employing continuous conveying, finished or semi-finished Sachima (a type of Chinese pastry) is transported via conveyor belts. However, due to the impact during cutting or slicing, and the unavoidable vibrations during conveyor belt operation, the Sachima material is prone to random displacement on the conveyor belt during transport. This problem of poor centering or alignment directly affects the accuracy of subsequent spreading processes. Existing spreading mechanisms, which directly drop material from above without pre-aligning it, inevitably result in uneven coverage of the Sachima material. Specifically, some materials are over-spread, leading to waste, while others are under-spread or even missed, ultimately severely impacting the product's appearance consistency and internal quality stability, increasing the difficulty of product quality control, and causing additional raw material losses.

[0004] Therefore, this utility model proposes an automatic material spreading mechanism for Sachima to solve the technical shortcomings of the prior art, which is that Sachima material is prone to positional displacement during continuous conveying, resulting in the material spreading not being able to evenly cover the material surface. Utility Model Content

[0005] In view of the problems existing in the automatic material spreading mechanism for Sachima, such as the material being easily shifted during continuous conveying, resulting in uneven spreading coverage, and the difficulty of achieving precise quantitative control through a simple mechanical structure in traditional spreading methods, which leads to raw material waste and poor product quality consistency, this utility model aims to provide an improved automatic material spreading mechanism for Sachima that can effectively solve the above problems.

[0006] This utility model provides an automatic surface spreading mechanism for Sachima (a type of Chinese pastry), including: a support leg and a conveyor platform fixedly connected to the top of the support leg; a centering mechanism fixedly connected to the side wall of the support leg; a support frame spanning the conveyor platform; and a feeding mechanism fixedly connected to the bottom of the support frame.

[0007] The centering mechanism has a multi-link linkage structure, which includes a telescopic cylinder 1 fixedly connected to the side of the support leg, a transmission assembly fixedly connected to the output end of the telescopic cylinder 1, an inclined transmission plate 1 rotatably connected to the transmission assembly, a centering adjustment plate rotatably connected to the inclined transmission plate 1, and an inclined transmission plate 2 rotatably connected to the centering adjustment plate. The end of the inclined transmission plate 2 away from the centering adjustment plate is rotatably connected to the side wall of the support leg or the conveyor table.

[0008] Furthermore, the feeding mechanism and the support frame are combined by means of a sliding groove. The feeding mechanism specifically includes a sliding groove fixedly connected to the bottom of the support frame, a telescopic cylinder II fixedly connected to the side wall of the sliding groove, a transmission device fixedly connected to the output end of the telescopic cylinder II, a hopper slidably connected inside the sliding groove, a discharge valve set at the bottom of the hopper, and a discharge port located above the hopper. The transmission device is driven to reciprocate within the sliding groove by engaging with the outer wall of the hopper.

[0009] Preferably, the transmission assembly specifically consists of a transmission rod and a transmission column fixedly connected to the end of the transmission rod. The output end of the telescopic cylinder is fixedly connected to the transmission rod, and the outer wall of the transmission column is rotatably connected to the end of the inclined transmission plate, thereby converting the linear motion of the cylinder into the swinging and translational motion of the linkage mechanism.

[0010] Preferably, the centering and adjusting plate has a long strip-shaped plate structure. The centering and adjusting plate is located above the conveying surface of the conveyor table, and the length direction of the centering and adjusting plate is parallel to the conveying direction of the conveyor table. The centering and adjusting plate is used to translate towards the center position of the conveyor table under the drive of the first inclined transmission plate and the second inclined transmission plate, so as to correct the deviation of the material.

[0011] Preferably, the telescopic cylinder one has a telescopic direction that is perpendicular or parallel to the conveying direction of the conveyor table, and the centering mechanism is symmetrically arranged on both sides of the width direction of the conveyor table. The centering adjustment plates on both sides move inward synchronously to achieve bidirectional centering of the material.

[0012] Preferably, the bottom of the chute is provided with an L-shaped support plate, and the bottom of the chute is provided with a through groove for the material hopper to slide through; when the hopper slides above the L-shaped support plate, the discharge valve is closed by the L-shaped support plate to prevent material leakage; when the hopper slides out of the range of the L-shaped support plate, the discharge valve loses support and opens under the action of gravity or elastic element to scatter material.

[0013] Preferably, the side wall of the chute has a strip-shaped clearance hole for the transmission device to pass through, the outer wall of the hopper has a protruding structure, and the end of the transmission device has a slot that matches the shape of the protruding structure. The transmission device drives the hopper to slide along the length of the chute by engaging the protruding structure. The rigid connection method effectively avoids slippage during the transmission process.

[0014] Preferably, the discharge valve is constructed as a flap hinged to the bottom of the hopper, and the area of ​​the flap is designed to be greater than or equal to the area of ​​the opening at the bottom of the hopper to ensure a sealing effect when closed.

[0015] Preferably, the discharge port has a funnel-shaped structure, the discharge end of the discharge port is directly opposite the initial receiving position of the silo, and the volume of the silo corresponds to the preset amount required for a single feeding process, thereby realizing volumetric quantitative feeding.

[0016] Preferably, the support frame is arranged in a U-shape across the conveyor platform, and the chute is horizontally fixed below the crossbeam of the support frame, so that the feeding mechanism can be stably suspended directly above the material.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problem in the prior art that the material of Sachima is prone to positional deviation during the conveying process, resulting in inaccurate sprinkling position and uneven coverage. It achieves the technical effect of automatically and forcibly centering the material on the conveying table, ensuring uniform sprinkling, reducing material waste, and optimizing product quality control. By setting a centering mechanism on the side wall of the support leg, using a telescopic cylinder to drive the transmission component, and cooperating with the inclined transmission plate and centering adjustment plate to form a multi-link linkage structure, it solves the problem of inaccurate sprinkling position and uneven coverage caused by the positional deviation of Sachima material during the conveying process.

[0018] 2. This utility model, by setting up a feeding mechanism including a chute, a hopper and a discharge valve, uses a telescopic cylinder to drive the hopper to slide in the chute, and coordinates with the support structure at the bottom of the chute to control the mechanical automatic opening and closing of the discharge valve. This solves the problems of the traditional feeding method in the prior art, which makes it difficult to accurately control the amount of material fed at one time, easily causes raw material waste and poor quality consistency of different batches of products. It achieves the technical effect of using volumetric method combined with mechanical displacement to achieve precise quantitative feeding, ensuring high consistency of product quality without complex electrical control, and reducing production costs.

[0019] 3. This utility model solves the problem of unstable connection of transmission components that are prone to slippage or detachment in the prior art by adopting a rigid connection method in which the slot on the transmission device cooperates with the protruding structure on the outer wall of the hopper, and the guiding and limiting effect of the chute on the hopper. It achieves the technical effect of improving the stability of the mechanism, extending the service life of the equipment and reducing the difficulty of maintenance. Attached Figure Description

[0022] Example: Reference Figures 1 to 5 This utility model provides an automatic material spreading mechanism for Sachima, which aims to solve the problems in the prior art where Sachima material is easily shifted during transportation on a conveyor belt, resulting in uneven spreading, and the difficulty in achieving precise quantitative control through a simple mechanical structure in traditional spreading methods, thus causing raw material waste.

[0023] like Figure 1 and Figure 3As shown, the automatic material spreading mechanism for Sachima includes a support leg 1 and a conveyor platform 2 fixedly connected to the top of the support leg 1. The support leg 1 serves as the foundation for the entire device, vertically placed on the ground to provide stable support. The conveyor platform 2 is horizontally fixedly installed at the top of the support leg 1, forming a continuous material conveying plane. The conveyor platform 2 is used to carry the semi-finished Sachima and continuously convey it to the downstream workstation in a predetermined direction. A centering mechanism 3 is fixedly connected to the side wall of the support leg 1. The centering mechanism 3 is symmetrically arranged on both sides of the conveyor platform 2 along its length. It is used to synchronously push the material on the conveyor platform 2 that might deviate before the spreading process, forcing the material back to the central axis of the conveyor platform 2. A support frame 5 spans above the conveyor platform 2. The support frame 5 has a U-shaped structure that spans the conveyor surface of the conveyor table 2, and its bottom support legs are fixedly connected to both sides of the conveyor table 2 frame or the ground. The material feeding mechanism 4 is fixedly connected to the bottom of the crossbeam at the top of the support frame 5. The material feeding mechanism 4 is located downstream of the centering mechanism 3 and is used to receive the raw material fed into the feeding port 6 and to quantitatively spread the material on the surface of the centered Sachima. The feeding port 6 has a funnel-shaped structure and is fixedly installed on the upper surface of the crossbeam of the support frame 5, and its discharge end extends vertically downward and is aligned with the receiving position of the material feeding mechanism 4. Through the positional coordination and rigid connection of the support legs 1, the conveyor table 2, the centering mechanism 3, the material feeding mechanism 4 and the support frame 5, a Sachima processing platform integrating automatic correction centering and mechanical quantitative spreading functions is constructed.

[0024] Reference Figure 1 , Figure 3 and Figure 4 The centering mechanism 3 includes a telescopic cylinder 31 fixedly connected to the side wall of the support leg 1. The telescopic cylinder 31 serves as the active power source, and the telescopic direction of its output end is set parallel to or at a preset angle to the conveying direction of the conveyor table 2. A transmission assembly 32 is fixedly connected to the output end of the telescopic cylinder 31. The transmission assembly 32 specifically includes a transmission rod 321 extending coaxially with the telescopic cylinder 31 and a transmission column 322 vertically fixed at the end of the transmission rod 321. One end of an inclined transmission plate 33 is rotatably connected to the outer wall of the transmission column 322, and the other end of the inclined transmission plate 33 is rotatably connected via a pin. There is a centering adjustment plate 34, which is a long strip plate structure and is suspended above the conveying surface of the conveyor table 2. The end of the centering adjustment plate 34 away from the inclined transmission plate 33 is rotatably connected to the inclined transmission plate 35. The end of the inclined transmission plate 35 away from the centering adjustment plate 34 is rotatably connected to the support leg 1 or the side wall of the conveyor table 2, thus forming a kinematic chain of "telescopic cylinder 31 driving, linkage transmission, and plate translation". The structure is transformed into the pushing motion of the centering adjustment plate 34 towards the center line of the conveyor table 2 through the linear motion of the telescopic cylinder 31, ensuring that the material is always in the optimal feeding position.

[0025] At the same time, please refer to Figure 1 and Figure 5A chute 44 is fixedly connected below the top crossbeam of the support frame 5. The chute 44 extends along the conveying direction perpendicular to the conveyor table 2. A telescopic cylinder 41 is fixedly connected to the side wall of the chute 44. A transmission device 42 is fixedly connected to the output end of the telescopic cylinder 41. A strip-shaped clearance hole is provided on the side wall of the chute 44 for the transmission device 42 to pass through and follow its movement. The end of the transmission device 42 extends into the interior of the chute 44. The cross-sectional shape of the inner cavity of the chute 44 is adapted to the shape of the top edge of the hopper 43, so that the hopper 43 can be stably slidably connected to the interior of the chute 44. The chute 44 provides precise guidance for the reciprocating movement of the hopper 43. The cooperation of the telescopic cylinder 41, the transmission device 42 and the chute 44 provides a stable driving and guiding foundation for the subsequent quantitative feeding action. For the pneumatic control system that drives the telescopic cylinder 31 and the telescopic cylinder 41, those skilled in the art can use conventional methods such as electromagnetic valve groups and PLC controllers to implement it. Its specific control logic is a well-known technology in the field and will not be described in detail here.

[0026] In a preferred embodiment, in order to achieve mechanical automatic opening and closing control based on position change and simplify the control logic, an L-shaped support plate is fixedly provided at the bottom of the chute 44, and a through groove is provided along the length direction of the bottom of the feeding bin 43 for sliding. When the bin 43 is located in the area above the L-shaped support plate, the discharge valve 45 at the bottom of the bin 43 is kept in a horizontal closed state by being pushed against by the top surface of the L-shaped support plate, thereby preventing spillage and leakage during material receiving and movement. When the bin 43 slides along the chute 44 under the drive of the transmission device 42 until it is out of the range of the L-shaped support plate, the discharge valve 45 loses the bottom support force and flips downward to open under its own weight or the action of the auxiliary elastic element to perform the material dispensing action.

[0027] To address the connection details of the drive transmission and ensure the stability of power transmission, the side wall of the slide 44 is provided with a strip-shaped clearance hole along the axial direction for the transmission device 42 to pass through. The outer wall of the hopper 43 is integrally formed with a protruding structure. The end of the transmission device 42 is provided with a slot that matches the shape of the protruding structure. The transmission device 42 drives the hopper 43 to slide linearly back and forth in the slide 44 by engaging the protruding structure with the slot. The rigid connection method avoids slippage or detachment during the transmission process.

[0028] Regarding the specific structure of the discharge valve 45, the discharge valve 45 is specifically a flap structure hinged to the bottom outlet of the hopper 43. The flap area is designed to be greater than or equal to the bottom opening area of ​​the hopper 43 to ensure sealing when closed. At the same time, in order to achieve accurate quantitative feeding, the effective volume of the hopper 43 is set to be equal to the preset amount required for a single feeding process, and the accuracy of single feeding is controlled by volume metering.

[0029] In coordination with the feeding process and the overall support layout, the discharge port 6 is designed as a funnel-shaped structure with a larger top and a smaller bottom. The discharge end of the discharge port 6 is vertically downward and directly opposite the receiving position of the hopper 43 when it is in the initial reset state. The support frame 5 is set in a gate shape across the conveying path of the conveyor table 2. The chute 44 is horizontally suspended and fixed below the top crossbeam of the support frame 5 to ensure that the feeding mechanism 4 is suspended directly above the Sachima material.

[0030] The working principle is as follows: When it is necessary to spread the material on the conveyor table 2 supported by the support leg 1, the centering mechanism 3 fixed to the side wall of the support leg 1 is activated first. The telescopic cylinder 31 drives the transmission rod 321 fixed at the drive end to move linearly through its telescopic action, which in turn drives the transmission column 322 at the end of the transmission component 32 to move synchronously. When the transmission column 322 starts to move, it drives one end of the inclined transmission plate 33 to swing through the rotational connection, which in turn pulls the centering adjustment plate 34, which is rotatably connected to the other end of the inclined transmission plate 33, to move. At this time, the other end of the centering adjustment plate 34 is supported and limited by the rotation of the inclined transmission plate 35, so that the centering adjustment plate 34 moves smoothly towards the center above the conveying surface of the conveyor table 2. Through the synchronous cooperation of the centering mechanisms 3 symmetrically arranged at both ends of the conveyor table 2, the Sachima material on the conveyor table 2 is forced to move to the center of the conveyor belt, thereby effectively ensuring the uniformity of subsequent spreading and optimizing product quality control, while reducing the waste of raw materials caused by material deviation and improving the stability of equipment operation.

[0031] When the material is conveyed to the spreading area after centering, the feeding mechanism 4, which is suspended and supported by the support frame 5, starts to work. The material is pre-stored in the hopper 43 of the feeding mechanism 4 from the feeding port 6. When the hopper 43 accumulates enough material to meet the spreading requirements of a single process, the telescopic cylinder 41 fixed on the side wall of the chute 44 is activated. Its telescopic movement drives the drive unit 42, which is fixed at the drive end, to move axially. The drive unit 42 uses its end slot to engage with the protruding structure on the outer wall of the hopper 43, thereby smoothly driving the hopper 43 to slide on the groove or through groove opened inside the chute 44. In the initial sliding phase, the discharge valve 45 at the bottom of the hopper 43 is kept closed by the L-shaped support plate at the bottom of the chute 44. When the bottom of the hopper 43 completely slides away from the L-shaped support plate at the bottom of the chute 44, the discharge valve 45 at the bottom of the hopper 43 loses its support and automatically flips downwards and opens under its own gravity or the action of the return spring, allowing the internal quantitative material to fall and cover the surface of the Sachima. The process utilizes the principle of mechanical displacement combined with gravity release, achieving precise quantitative feeding without the need for complex electronic control induction, which can ensure a high degree of consistency in the quality of different batches of products.
