Description

Technical Field

[0001] The invention relates to the technical field of pepper conveying, and in particular to a material shifting mechanism of a pepper capping machine and a use method thereof. Background Art

[0002] A pepper decapping machine is a device used to remove the "cap" on the top of peppers. Generally speaking, the device contains a rotating blade or roller. The peppers enter through the feed port, and the machine cuts off the top of the peppers by rotating the blade or roller. This decapping equipment is usually designed for efficient and continuous operation, which can save manual operation time and improve decapping efficiency.

[0003] A feeding conveying device is usually provided at the feeding port of the pepper decapping machine. A scraper conveyor is generally used to convey the pepper raw materials to the interior of the decapping machine. The peppers fall from the hopper above the conveyor to the surface of the conveyor. During the unloading process, since the peppers are small in size and intertwined with each other, they will accumulate on the conveyor during the initial unloading and are not easy to disperse in time, which may easily cause the peppers to scatter outward. In addition, the surface of the peppers is easily squeezed by the scraper conveyor belt when piled up, resulting in surface damage, which is not conducive to protecting the integrity of the pepper body before decapping. In addition, due to the aperture limitation at the end of the drum-type pepper decapping machine, after the peppers are decapped, they need to be manually shoveled out, which is very inconvenient to operate. Therefore, it needs to be improved. Summary of the invention

[0011] Preferably, torsion springs are provided on both sides of the shovel bucket, and the ends of the torsion springs abut against one group of mounting rods. An inclined rod is fixedly connected to the top of the arc frame, and the inclined rod contacts the edge of the shovel bucket. The function of the inclined rod is to flip the shovel bucket to pour the peppers into the hopper.

[0012] Preferably, the material discharging and shifting assembly also includes a rear baffle in contact with the rear side of the material hopper, a pull rod is fixedly connected to the axis of the rear baffle, an end of the pull rod away from the rear baffle is fixedly connected to a slide seat, and both sides of the slide seat are slidably connected to the front side of the material hopper.

[0014] Preferably, the material discharging and shifting mechanism further includes a shifting plate, and the shifting plate is fixedly connected to another set of mounting rods.

[0015] Preferably, a method for using a material-selecting mechanism of a pepper capping machine comprises the following steps:

[0016] S1: When the caps of peppers are removed, the driving motor in the transmission assembly is started to drive the conveyor to run. While the conveyor is running, the wheel disc is driven to rotate continuously through the pulley group 1. When the wheel disc rotates, it drives the transmission rod to move. When the transmission rod is driven, the end of the transmission rod away from the wheel disc drives the swing arm to swing downward. In this process, the rotating rod is driven to swing downward, and the connection between the swing arm and the rotating block slides. The rotating rod drives the material box downward to the surface of the conveyor. During this process, the rollers installed at both ends of the sealing plate are blocked by the blocking rod, so that the sealing plate of the material box is opened during the rotation, and the spring 1 is gradually compressed. At the same time, during the opening process of the sealing plate, the peppers in the material box are scattered downward. , evenly falling on the conveyor belt of the conveyor. As the turntable continues to rotate, the transmission rod is pulled back, so that the swing arm drives the rotating rod and the cloth box to return upward. When the cloth box returns, the spring 1 automatically returns, so that the sealing plate blocks the side wall of the cloth box. After rotating ninety degrees during the return process of the cloth box, the cloth box runs horizontally and pushes the U-shaped hanger to move the discharge rod in the moving direction of the cloth box, pushing one of the baffles open, and the other baffle set opposite to it automatically opens, so that the bottom of the lower hopper is aligned with the top opening of the cloth box when it is opened. When the cloth box continues to move downward, the two baffles are automatically returned by the spring 2 and the discharge rod, and the bottom of the lower hopper is automatically closed;

[0017] S2: After the peppers are transported by the conveyor and enter the decapping machine for processing, the decapped peppers are piled up at the front end of the decapping machine. At this time, the decapping machine is rotating, and the gear piece fixed at the front end drives the gear meshing with it to rotate. The gear drives the front ring body to rotate continuously through the second pulley group. The front ring body and the rear ring body respectively drive the shovel bucket and the paddle to rotate synchronously through the mounting rod. The rotation direction of the shovel bucket and the paddle is opposite to that of the decapping machine. The bucket shovels the peppers accumulated inside the decapping machine during the rotation process. When the shovel bucket rotates upward, the shovel bucket is set at the shovel. The torsion springs at both ends of the hopper prevent the shovel hopper from rotating on its own and rotate around the hopper as the axis. As the shovel hopper continues to move upward, the edge of the shovel hopper touches the inclined rod, compressing the torsion springs on both sides of the shovel hopper and causing the shovel hopper to rotate on its own. Above the hopper, the peppers in the shovel hopper are dumped down and fall into the hopper. After the shovel hopper continues to move, its edge is disconnected from the inclined rod, and the torsion spring returns to its original position, causing the shovel hopper to return to its original position. When the shovel hopper rotates to the top of the hopper, the paddle can poke the peppers to spread some of them to one side to prevent excessive accumulation.

[0018] S3: In the process of shoveling the peppers in the pepper decapping machine, the conical wheel 1 rotates synchronously with the front ring body through the pulley group 2, and the conical wheel 1 drives the conical wheel 2 on the top to rotate synchronously. When the conical wheel 2 rotates, it drives the end to slide in the guide groove on the slide seat through the wheel plate, so that the slide seat is pulled outward, and the slide seat slides on the front side of the hopper. In the process, the slide seat drives the pull rod to pull the rear baffle plate outward, so that the rear baffle plate pushes the peppers in the hopper outward, so that the peppers are taken out from the inside of the decapping machine and fall from the discharge table along the hopper.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In the present invention, the material distribution box is provided, and during the feeding process, the belt pulley group 1 and the conveyor are synchronously operated, so that the material distribution box can catch the peppers falling from the lower hopper, and through the rotation of the turntable, the swing arm drives the rotating rod to rotate, so that the material distribution box rotates downward by 90 degrees. When the material distribution box is in an inclined state, the sealing plate on the side is opened, and the peppers gradually leak out, smoothly contact the surface of the conveyor belt, and are scattered in the middle of the conveyor belt, which can prevent friction with the edge of the conveyor belt, not only can the peppers be weighed and the quality of the peppers fed is kept consistent, but also the surface of the peppers can be protected to prevent damage;

[0021] 2. In the present invention, by setting the shoveling bucket, when the pepper decapping machine rotates, the shoveling bucket can scoop up the peppers inside the decapping machine and lift them upward. When the shoveling bucket contacts the inclined rod, the shoveling bucket can be turned over above the material hopper, and the peppers in the shoveling bucket automatically fall into the material hopper. Then, through the torsion spring, the shoveling bucket automatically returns to its position and performs the shoveling operation again. After the peppers are decapped, the peppers can be automatically scooped up, thereby improving the efficiency of the pepper decapping operation.

[0022] 3. In the present invention, by means of the set pull rod and rear baffle, the pulley group 2 drives the conical wheel 1 to rotate synchronously during operation, so that the slide seat slides outward, driving the pull rod and the rear baffle to move outward synchronously. During the process, the rear baffle can directly push out the peppers in the hopper, and the peppers that have been decapped are directly discharged from the interior of the decapping machine, so that the peppers can be automatically discharged and selected.

[0043] The use method and advantages of the present invention: The use method of the material-selecting mechanism of the pepper cap-removing machine, the working process is as follows:

[0044] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 As shown:

[0045] S1: When the capping operation of peppers is carried out, the driving motor in the transmission component 3 is started to drive the conveyor 2 to run. While the conveyor 2 is running, the pulley group 1 502 drives the wheel disc 719 to rotate continuously. When the wheel disc 719 rotates, it drives the transmission rod 504 to move. When the transmission rod 504 is driven, the end of the transmission rod 504 away from the wheel disc 719 drives the swing arm 505 to swing downward. In this process, the rotating rod 506 is driven to swing downward, and the connection between the swing arm 505 and the rotating block 507 slides. The rotating rod 506 drives the cloth box 508 downward to the surface of the conveyor 2.

[0046] S2: After the peppers are transmitted by the conveyor 2 and enter the decapping machine 1 for processing, the decapped peppers are piled up at the front end of the decapping machine 1. At this time, the tooth piece 6 fixedly installed at the front end of the decapping machine 1 drives the gear 702 meshing with it to rotate, and the gear 702 drives the front ring body 703 to rotate continuously through the pulley group 2 701. The front ring body 703 and the rear ring body 708 respectively drive the shovel bucket 709 and the paddle plate 712 to rotate synchronously through the mounting rod 707. The rotation direction of the shovel bucket 709 and the paddle plate 712 is opposite to that of the decapping machine 1. The shovel bucket shovels the peppers piled up inside the decapping machine 1 during the rotation process. When the shovel bucket 709 rotates upward, the torque Spring 710 prevents the shovel bucket 709 from self-rotation and rotates around the material hopper 704. As the shovel bucket 709 continues to move upward, the edge of the shovel bucket 709 touches the inclined rod 711, so that the torsion springs 710 on both sides of the shovel bucket 709 are compressed, and the shovel bucket 709 self-rotates.

[0047] S3: During the process of shoveling the peppers in the pepper decapping machine 1, the conical wheel 1 717 rotates synchronously with the front ring body 703 through the pulley group 2 701, and the conical wheel 1 717 drives the conical wheel 2 718 on the top to rotate synchronously. When the conical wheel 2 718 rotates, it drives the end 720 to slide in the guide groove 716 on the slide 715 through the wheel plate 719, so that the slide 715 is pulled outward, and the slide 715 slides on the front side of the hopper 704. During the process, the slide 715 drives the pull rod 714 to pull the rear baffle 713 outward, so that the rear baffle 713 pushes the peppers in the hopper 704 outward, so that the peppers are taken out from the inside of the decapping machine 1 and fall from the discharge table 705 along the hopper 704.

10. The method for using the material-selecting mechanism of the pepper capping machine according to claim 9, characterized in that: The steps include: S1: When the capping operation of peppers is performed, the driving motor in the transmission assembly (3) is started to drive the conveyor (2) to operate. While the conveyor (2) is operating, the wheel disc (719) is driven to rotate continuously through the belt pulley group (502). When the wheel disc (719) rotates, the transmission rod (504) is driven to move. When the transmission rod (504) is driven, the end of the transmission rod (504) away from the wheel disc (719) drives the swing arm (505) to swing downward, and in the process, the rotating rod (506) is driven downward. The swing arm (505) and the rotating block (507) are swung, and the connection between the swing arm (505) and the rotating block (507) slides, and the rotating rod (506) drives the material box (508) downward to approach the surface of the conveyor (2). During the process, the rollers (512) installed at both ends of the sealing plate (510) are blocked by the blocking rod (509), so that the material box (508) is rotated, the sealing plate (510) is opened, and the spring (511) is gradually compressed. At the same time, during the opening process of the sealing plate (510), the spicy in the material box (508) is compressed. The peppers are scattered downward and evenly fall on the conveyor belt of the conveyor (2). As the turntable (503) continues to rotate, the transmission rod (504) is pulled back, so that the swing arm (505) drives the rotating rod (506) and the material box (508) to return upward. When the material box (508) returns, the spring (511) automatically returns, so that the sealing plate (510) blocks the side wall of the material box (508). After the material box (508) rotates ninety degrees during the return process, the material box (508) runs horizontally. and push the U-shaped hanger (514) to move the discharge rod (513) in the moving direction of the material box (508), push one of the baffles (8) open, and the other baffle (8) arranged opposite to it automatically opens, so that the bottom of the discharge hopper (4) is aligned with the top opening of the material box (508) when it opens. When the material box (508) continues to move downward, the two baffles (8) are automatically returned to their original positions through the spring 2 (515) and the discharge rod (513), and the bottom of the discharge hopper (4) is automatically closed; S2: After the peppers are transported by the conveyor (2) into the decapping machine (1) for processing, the decapped peppers are accumulated at the front end of the decapping machine (1). At this time, the decapping machine (1) is rotating, and the toothed plate (6) fixed at the front end drives the gear (702) meshing with it to rotate. The gear (702) drives the front ring body (703) to rotate continuously through the pulley group 2 (701). The front ring body (703) and the rear ring body (708) respectively drive the shovel bucket (709) and the paddle plate (712) to rotate synchronously through the mounting rod (707). The rotation direction of the shovel bucket (709) and the paddle plate (712) is opposite to that of the decapping machine (1). The shovel bucket shovels the peppers accumulated inside the decapping machine (1) during the rotation process. When the shovel bucket (709) rotates upward, the shovel bucket (709) is provided at both ends of the shovel bucket (709). The torsion spring (710) prevents the shovel bucket (709) from self-rotation and rotates around the material hopper (704). As the shovel bucket (709) continues to move upward, the edge of the shovel bucket (709) touches the inclined rod (711), so that the torsion springs (710) on both sides of the shovel bucket (709) are compressed, and the shovel bucket (709) self-rotates. Above the material hopper (704), the peppers in the shovel bucket (709) are dumped down and fall into the interior of the material hopper (704). After the shovel bucket (709) continues to move, its edge is disconnected from the inclined rod (711), and the torsion spring (710) returns to its original position, so that the shovel bucket (709) returns to its original position. When the shovel bucket (709) rotates to the top of the material hopper (704), the paddle (712) can pry the peppers so that some of the peppers are scattered to one side to prevent excessive accumulation. S3: During the process of shoveling the peppers in the pepper decapping machine (1), the conical wheel 1 (717) rotates synchronously with the front ring body (703) through the pulley group 2 (701), and the conical wheel 1 (717) drives the conical wheel 2 (718) on the top to rotate synchronously. When the conical wheel 2 (718) rotates, it drives the end (720) to slide in the guide groove (716) on the slide seat (715) through the wheel plate (719), so that the slide seat (715) is pulled outward, and the slide seat (715) slides on the front side of the hopper (704). During the process, the slide seat (715) drives the pull rod (714) to pull the rear baffle plate (713) outward, so that the rear baffle plate (713) pushes the peppers in the hopper (704) outward, so that the peppers are taken out from the inside of the decapping machine (1) and fall from the discharge platform (705) along the hopper (704).
