Description

Technical Field

[0001] This invention belongs to the technical field of feeding equipment, specifically relating to a sesame ball packaging and feeding conveyor line and its control method. Background Technology

[0002] To reduce labor and improve production efficiency, complete automated production lines for sesame balls have appeared on the market. In order to improve the taste of sesame balls and ensure that the ingredients are highly viscous and not loose, the syrup content in sesame balls is often high. This causes the sesame balls to stick together in the packaging machine after forming. It is necessary to arrange staff to separate the sticky sesame balls one by one before they enter the packaging machine, which affects the processing efficiency and has a low degree of automation. Summary of the Invention

[0003] To address the problems existing in the prior art, this invention provides a sesame seed ball packaging and feeding conveyor line and its control method, which can automatically send the formed sesame seed balls to the packaging machine, reduce the adhesion between sesame seed balls during the conveying process, and separate sesame seed balls that are stuck together, effectively reducing the degree of manual intervention.

[0004] The specific technical solution adopted in this invention is as follows:

[0005] A sesame seed ball packaging and conveying line includes a frame and a conveying assembly mounted on the frame and located between a forming machine and a packaging machine. The key feature is that the conveying assembly includes a first elevator, a horizontal conveyor belt, a movable hopper, and a set of spaced-apart vibrating discs arranged sequentially along the conveying direction. The inlet end of the first elevator is connected to the forming machine, and the outlet end of the vibrating discs is connected to the packaging machine. The vibrating discs are connected to the movable hopper via slide rails. Movable plates and fixed plates, fixedly connected to the movable hopper, are respectively provided on both sides of the bottom of the movable hopper. The movable plates and fixed plates are inclined to form a V-shaped structure. The end of the movable plate adjacent to the fixed plate is hinged to the movable hopper via a hinge shaft. The movable plate has a degree of freedom to rotate along the hinge shaft via a drive assembly. A set of spaced-apart baffles is provided inside the movable hopper, and the gap between two adjacent baffles forms a discharge channel. The width of the discharge channel is greater than the diameter of the sesame seed ball. A set of rakes adjacent to the fixed plate and located within the discharge channel is provided on the movable plate.

[0006] The conveying direction of the horizontal conveyor belt is perpendicular to the conveying direction of the first elevator. The feed end of the horizontal conveyor belt is located below the discharge end of the first elevator. A baffle is provided between the horizontal conveyor belt and the discharge end of the first elevator. The discharge end of the horizontal conveyor belt extends outward from the baffle along its conveying direction.

[0007] The slide is connected to the frame by means of springs.

[0008] The width of the material feeding channel is 1.1-1.3 times the diameter of the sesame balls.

[0009] A cooling chamber is also provided between the molding machine and the first elevator. The cooling chamber is equipped with a cooling belt connected to the discharge end of the molding machine. The inlet end of the cooling belt is connected to the discharge end of the molding machine, and the discharge end of the cooling belt is connected to the inlet end of the first elevator.

[0010] The cooling belt includes a set of sub-conveyor belts arranged sequentially from top to bottom. The feed end of the top sub-conveyor belt is connected to the discharge end of the forming machine via a second elevator, and the discharge end of the bottom sub-conveyor belt is connected to the feed end of the first elevator. An S-shaped cooling channel is formed between adjacent sub-conveyor belts.

[0011] The drive assembly includes a first winch mounted on a movable hopper, wherein the winch rope is connected to a movable plate.

[0012] The frame is equipped with a slide rail that matches the movable hopper, and the movable hopper has the freedom to reciprocate along the slide rail.

[0013] The control method for this sesame seed ball packaging and feeding conveyor line includes the following steps:

[0014] S1. The first elevator lifts the formed sesame balls above the horizontal conveyor belt and then drops them onto the horizontal conveyor belt.

[0015] S2. The moving hopper moves to below the horizontal conveyor belt, and the horizontal conveyor belt turns in the opposite direction to transport sesame balls to the moving hopper;

[0016] S3. After the sesame balls are conveyed, the horizontal conveyor belt reverses and then stops rotating;

[0017] S4. The moving hopper moves to the vibrating plate, and the drive component drives the movable plate to open and close 3-5 times to complete the feeding. The movable plate closes, and the moving hopper moves to the horizontal conveyor belt. Repeat steps S2-S4.

[0018] The beneficial effects of this invention are:

[0019] This invention utilizes a first elevator to transport sesame balls to a high position and drop them onto a horizontal conveyor belt. The horizontal conveyor belt then transports the sesame balls to a moving hopper, which sequentially feeds them into various vibrating discs. Once the moving hopper reaches its corresponding vibrating disc, a movable plate opens, allowing the sesame balls to fall onto a slide and roll into the vibrating disc. The vibrating disc vibrates to prevent the sesame balls from sticking together and then transports them to a packaging machine for packaging. Due to the design of the discharge channel, clumps of sesame balls cannot fall to the bottom of the moving hopper and therefore cannot fall onto the slide. Simultaneously, as the movable plate opens, a rake enters through the discharge channel, agitating the sesame balls stuck together above the baffle, separating them and allowing them to fall onto the slide along the discharge channel. The horizontal conveyor belt reduces the traveling distance of the moving hopper. Furthermore, during the movement of the moving hopper, the horizontal conveyor belt temporarily stores the sesame balls output by the first elevator, eliminating the need to pause the first elevator and the forming machine. This also reduces the waiting time for the moving hopper to receive sesame balls, effectively improving the efficiency of packaging and unloading. Attached Figure Description

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0028] Specific implementation examples Figure 1-6As shown, a sesame seed ball packaging and conveying line includes a frame 1 and a conveying assembly mounted on the frame 1 and located between a forming machine and a packaging machine. The conveying assembly includes a first elevator 2, a horizontal conveyor belt 3, a movable hopper 4, and a set of spaced-apart vibrating discs 5 arranged sequentially along the conveying direction. The discharge end of the vibrating discs 5 is connected to the packaging machine. A cooling chamber is also provided between the forming machine and the first elevator 2. The cooling chamber contains a cooling belt connected to the discharge end of the forming machine. The inlet end of the cooling belt is connected to the discharge end of the forming machine, and the discharge end of the cooling belt is connected to the inlet end of the first elevator 2. The cooling belt includes a set of sub-conveyor belts 13 arranged sequentially from top to bottom. The feed end of the top sub-conveyor belt 13 is connected to the discharge end of the forming machine via a second elevator, and the discharge end of the bottom sub-conveyor belt 13 is connected to the feed end of the first elevator 2. An S-shaped cooling channel is formed between two adjacent sub-conveyor belts 13. After being lifted by the second elevator, the sesame balls fall onto the top sub-conveyor belt 13, and then sequentially fall onto the lower sub-conveyor belt 13. The cooling is carried out in layers and along a long path. This cooling belt occupies a small area and has a long cooling channel path, which fully cools and hardens the sesame balls, improves the dispersion between the sesame balls, and prevents the sesame balls from sticking together.

[0029] After cooling, the sesame balls are lifted to a high position by the first elevator 2 and fall onto the horizontal conveyor belt 3. The conveying direction of the horizontal conveyor belt 3 is perpendicular to the conveying direction of the first elevator 2. The conveying length of the horizontal conveyor belt 3 is greater than the width of the first elevator 2. The feed end of the horizontal conveyor belt 3 is located below the discharge end of the first elevator 2. A baffle 12 is provided between the horizontal conveyor belt 3 and the discharge end of the first elevator 2. The discharge end of the horizontal conveyor belt 3 extends outward along its conveying direction. The baffle 12 and the extended discharge end prevent the sesame balls falling off the horizontal conveyor belt 3. At the same time, during the reverse rotation and when the horizontal conveyor belt 3 stops rotating, the baffle 12 provides a barrier for the sesame balls, and the extended discharge end provides a buffer distance for the sesame balls to roll, preventing them from falling off due to inertia.

[0030] The frame 1 is equipped with a slide rail 15 that matches the movable hopper 4. The movable hopper 4 has the freedom to reciprocate along the slide rail 15. A second winch 17 is respectively installed at both ends of the slide rail 15 on the frame 1. The second winch 17 is an electric winch. The ropes on the two second winches 17 are respectively connected to the two ends of the movable hopper 4. When the movable hopper 4 picks up material, the second winch 17 near the first elevator 2 tightens, causing the movable hopper 4 to move along the slide rail 15 toward the first elevator 2. After the movable hopper 4 finishes picking up material, the other second winch 17 tightens, pulling the movable hopper 4 along the slide rail 15 to the vibrating plate 5.

[0031] The vibratory feeder 5 is connected to the movable hopper 4 via slide rails 6. Movable plates 7 and fixed plates 8, fixedly connected to the movable hopper 4, are respectively provided on both sides of the bottom of the movable hopper 4. The movable plates 7 and fixed plates 8 are inclined to form a V-shaped structure. The movable plates 7 are hinged to the movable hopper 4 via hinge shafts 9 and have the freedom to rotate along the hinge shafts 9 via a drive assembly. A set of spaced-apart baffles 10 are provided inside the movable hopper 4. The gap between two adjacent baffles 10 forms a feeding channel for sesame balls. The width of the feeding channel is 1.1-1.3 times the diameter of the sesame balls. Individual sesame balls and rows of sesame balls that are parallel to the feeding channel can fall to the bottom of the movable hopper 4 through the feeding channel. Sesame balls that are clumped together or rows of sesame balls that intersect the feeding channel are supported horizontally on the baffles 10. A set of baffles adjacent to the fixed plates 8 and located in the feeding channel are provided on the movable plates 7. When the rake bar 11 and movable plate 7 in the channel open, the sesame balls at the bottom of the moving hopper 4 fall onto the slide 6. The rake bar 11 enters the upper part of the baffle 10 along the material discharge channel, stirring the sesame balls that are supported on the baffle 10, causing the sticky sesame balls to separate and fall onto the slide 6 along the material discharge channel. During one feeding process of the moving hopper 4, the movable plate 7 opens and closes repeatedly 3-5 times, preferably 4 times in this embodiment, so that the rake bar 11 can fully separate the sticky sesame balls on the baffle 10. The bottom and side walls of the slide 6 are connected to the frame 1 by means of springs 16. When the movable plate 7 opens, the sesame balls fall onto the slide 6 and strike the slide 6, causing the slide 6 to vibrate. The sesame balls bounce on the slide 6, making it easy for the sticky sesame balls to separate. The sesame balls enter the vibrating plate 5 and are vibrated by the vibrating plate 5 to prevent sticking. This eliminates the need for manual separation of the sticky sesame balls, reduces the degree of manual intervention, and effectively improves work efficiency.

[0032] The drive assembly includes a first winch 14 mounted on the movable hopper 4. The winch rope on the first winch 14 is connected to the side of the movable plate 7 away from the fixed plate 8. When the first winch 14 rotates clockwise, it tightens the winch rope, thus closing the movable plate 7; when the first winch 14 rotates counterclockwise, it loosens the winch rope, thus opening the movable plate 7. The first winch 14 is an electric winch, and the wires on the first winch 14 are connected to a fixed power source via a cable chain.

[0033] Both the first and second elevators are inclined baffle belt conveyors.

[0034] In this invention, each working component is controlled by a controller.

[0035] The control method for this sesame seed ball packaging and feeding conveyor line includes the following steps:

[0036] S1. The second elevator lifts the formed sesame balls to the cooling belt for cooling. After cooling, the sesame balls are sent to the first elevator 2. The first elevator 2 continues to lift the formed and cooled sesame balls above the horizontal conveyor belt 3 and drop them onto the horizontal conveyor belt 3.

[0037] S2, the moving hopper 4 moves to below the horizontal conveyor belt 3, and the horizontal conveyor belt 3 turns in the forward direction to transport sesame balls from the moving hopper 4;

[0038] S3. After the sesame balls are conveyed, the horizontal conveyor belt 3 reverses and then stops rotating;

[0039] The reversal distance of the horizontal conveyor belt 3 can be adjusted according to the actual situation. In this embodiment, the reversal distance of the horizontal conveyor belt 3 is 20cm. The reversal causes the sesame balls falling on the horizontal conveyor belt 3 to move away from the moving hopper 4 and be blocked by the baffle 12, preventing the sesame balls from rolling towards the discharge end of the horizontal conveyor belt 3 and falling onto the frame 1 or the ground. During the reversal and stopping process of the horizontal conveyor belt 3, the sesame balls conveyed by the first elevator 2 are temporarily stored in the moving hopper 4 while it is feeding the vibrating plate 5, and a sufficient amount of sesame balls are stored in the moving hopper 4. There is no need to stop the forming machine, the second elevator, the cooling belt and the first elevator 2. When the moving hopper 4 picks up the material, the horizontal conveyor belt 3 can quickly provide a sufficient amount of sesame balls to the moving hopper 4, reducing the waiting time of the moving hopper 4.

[0040] S4. The moving hopper 4 moves to the vibrating plate 5, and the drive assembly drives the movable plate 7 to open and close 3-5 times to complete the feeding. The movable plate 7 closes, and the moving hopper 4 moves to the horizontal conveyor belt 3. Repeat steps S2-S4.
