Description

Technical Field

[0001] This invention belongs to the field of chili pepper punching technology, specifically relating to a chili pepper punching machine. Background Technology

[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.

[0003] From fresh chili peppers to dried chili peppers, the process of dehydration is essential. Methods for dehydrating chili peppers include natural sun drying and oven drying. For large quantities of chili peppers, oven drying is generally used.

[0004] In chili drying, some methods use a segmented drying method, which involves initial drying, piling and sweating, followed by a second drying. Other methods involve punching holes in the chilies before drying. Punching holes can shorten the drying time and does not affect the quality of the dried chilies.

[0005] Currently, some chili pepper punching machines use a reciprocating punching plate to punch holes in the chilies. Feeding and unloading the chilies are done manually, which is time-consuming. Furthermore, after one punching operation, feeding must be completed before the next punching operation can begin, undoubtedly extending the overall punching time and resulting in low efficiency. Punching the chilies while they are being conveyed also makes it impossible to achieve uniform punching, resulting in poor punching quality. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the purpose of this invention is to provide a chili pepper punching machine. This device is equipped with two alternating needle plates, which can improve the efficiency of chili pepper punching.

[0007] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0008] In a first aspect, the present invention provides a chili punching machine, comprising a first conveyor belt and a second conveyor belt arranged in parallel, both conveyor belts moving from the feeding position to the punching position, and being punched by a chili punching device when transported to the punching position.

[0009] The chili pepper punching device includes a first needle plate disposed above a first conveyor belt and a second needle plate disposed above a second conveyor belt. Both the first needle plate and the second needle plate can move up and down to punch holes, and the two needle plates move in opposite directions at the same time to punch holes alternately.

[0010] As a further technical solution, the first conveyor belt and the second conveyor belt operate alternately, and when one conveyor belt is conveying, the other conveyor belt stops conveying; the first conveyor belt is connected to the first power device, and the second conveyor belt is connected to the second power device.

[0011] As a further technical solution, the first power unit is connected to the first electromagnetic clutch, and the first electromagnetic clutch is connected to the first reducer; the second power unit is connected to the second electromagnetic clutch, and the second electromagnetic clutch is connected to the second reducer.

[0012] As a further technical solution, when the first needle plate moves from top to bottom to punch holes, the first conveyor belt stops conveying; when the first needle plate moves from bottom to top, the first conveyor belt conveys. When the second needle plate moves from top to bottom to punch holes, the second conveyor belt stops conveying; when the second needle plate moves from bottom to top, the second conveyor belt conveys.

[0013] As a further technical solution, the first needle plate is connected to the needle plate shaft through a first crank-slider mechanism, the second needle plate is connected to the needle plate shaft through a second crank-slider mechanism, and the needle plate shaft is connected to a third power device.

[0014] As a further technical solution, a sleeve is fitted on the outer side of the needle plate shaft, and two fan-shaped blades are fixedly arranged on the sleeve. The two fan-shaped blades are axially spaced on the outer side wall of the sleeve, and the two fan-shaped blades are spaced at a phase angle.

[0015] As a further technical solution, one sector corresponds to a proximity switch and can contact the proximity switch; another sector corresponds to another proximity switch and can contact the proximity switch; when one sector is in contact with its corresponding proximity switch, the other sector is not in contact with its corresponding proximity switch.

[0016] As a further technical solution, the distance between the two proximity switches and the sleeve is equal to the radius of the sector + 1-2mm.

[0017] As a further technical solution, one proximity switch is connected to the first electromagnetic clutch via an AC contactor, and the other proximity switch is connected to the second electromagnetic clutch via another AC contactor, thereby controlling the movement of the first conveyor belt and the second conveyor belt.

[0018] As a further technical solution, both the first needle plate and the second needle plate have a flat plate, and the bottom of the flat plate is connected to the punching needle; a pinhole plate is provided between the first conveyor belt and the first needle plate, and between the second conveyor belt and the second needle plate. The pinhole plate has a pinhole corresponding to the punching needle. When the punching needle performs the punching action, it first passes through the pinhole plate and then punches the chili pepper.

[0019] The beneficial effects of the present invention are as follows:

[0020] The chili pepper punching machine of this invention uses two conveyor belts to transport chilies, with automatic loading and unloading, reducing working time. Then, two needle plates punch the chilies separately, and the two needle plates alternately move up and down to punch. After the conveyor belts transport the chilies to the punching position, the other needle plate immediately starts punching as one needle plate finishes punching, which can improve the efficiency of chili pepper punching. The two needle plates can complete the chili pepper punching work twice in one rotation cycle, doubling the efficiency. At the same time, the two needle plates move up and down alternately on a shaft, which can act as counterweights for each other to ensure the stability of the needle plates' up and down movement.

[0021] The chili pepper punching machine of the present invention uses two conveyor belts to alternately transport chilies. When one needle plate moves downward to perform the punching action, the conveyor belt corresponding to that needle plate stops moving, while the conveyor belt corresponding to the other needle plate transports chilies. The next needle plate punches chilies at the same time as the previous needle plate completes its punching, saving the waiting time for chilies to be transported. In addition, the punching operation is performed after the conveyor belt stops, which makes the chilies punched more evenly. At the same time, the stopping of the conveyor belt can ensure the accuracy of the punching position of the chilies, and will not cause the chilies to deviate due to the displacement caused by the circumferential motion of the needle plate during the falling and rising process.

[0022] In the chili pepper punching machine of the present invention, the needle plate moves up and down through a crank-slider mechanism. With the setting of the needle plate, when the punching needle on the needle plate performs the punching action, it first passes through the needle plate and then punches the chili pepper. When the needle plate completes the action and begins to move upward, the chili pepper can be prevented from moving upward with the needle plate. Attached Figure Description

Detailed Implementation

[0030] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0031] In a typical embodiment of the present invention, such as Figure 1 As shown, a chili pepper punching machine is proposed, which includes a frame 1, a first conveyor belt 2 and a second conveyor belt 3 arranged on the frame 1, the first conveyor belt and the second conveyor belt are arranged in parallel, the first conveyor belt 2 is connected to a first power device 4 through a first chain drive mechanism, and the second conveyor belt 3 is connected to a second power device 5 through a second chain drive mechanism.

[0032] In this embodiment, both the first power device 4 and the second power device 5 are electric motors, which transmit power to the conveyor belt to transport the chili peppers.

[0033] Both conveyor belts are set horizontally and move from the chili feeding position to the chili punching position. When the chili is transported to the chili punching position, the chili punching device punches holes.

[0034] A first electromagnetic clutch 9 and a first reducer 10 are provided between the first power unit 4 and the first chain drive mechanism. The first power unit 4 is connected to the first electromagnetic clutch 9, the first electromagnetic clutch 9 is connected to the first reducer 10, and the first reducer 10 is connected to the first chain drive mechanism.

[0035] A second electromagnetic clutch and a second reducer are provided between the second power unit 5 and the second chain drive mechanism. The second power unit 5 is connected to the second electromagnetic clutch, the second electromagnetic clutch is connected to the second reducer, and the second reducer is connected to the second chain drive mechanism.

[0036] The chili pepper punching device includes a first needle plate 6 and a second needle plate 7. The first needle plate 6 is positioned above the first conveyor belt 2, and the second needle plate 7 is positioned above the second conveyor belt 3. Both the first needle plate 6 and the second needle plate 7 can move up and down to punch holes in the chilies on the first conveyor belt 2 and the second conveyor belt 3, respectively.

[0037] Specifically, the first needle plate 6 is connected to the needle plate shaft 12 via the first crank-slider mechanism 11, the second needle plate 7 is connected to the needle plate shaft 12 via the second crank-slider mechanism 13, and the needle plate shaft 12 is connected to the third power device 8 via the third chain drive mechanism.

[0038] When punching holes in chili peppers, the two needle plates move in opposite directions. That is, when the first needle plate 6 moves from top to bottom to punch holes, the second needle plate moves from bottom to top.

[0039] In this embodiment, the third power device 8 is a motor, which transmits power to the crank-slider mechanism, thereby driving the needle plate to move up and down.

[0040] The needle plate shaft 12 is supported on the frame 1 by bearings and bearing seats. A sleeve 14 is fitted on the outside of the needle plate shaft 12, and two sector-shaped blades 15 are fixedly mounted on the sleeve 14. The two sector-shaped blades 15 are axially spaced on the outer wall of the sleeve 14, and the two sector-shaped blades 15 are spaced apart by a certain phase angle. A proximity switch fixing plate 16 is fixedly mounted on the frame 1, and two proximity switches 17 are mounted on the proximity switch fixing plate 16. One proximity switch corresponds to one sector-shaped blade, and the sector-shaped blade can contact the proximity switch; the other proximity switch corresponds to another sector-shaped blade, and the sector-shaped blade can contact the proximity switch. When one sector-shaped blade is in contact with its corresponding proximity switch, the other sector-shaped blade is not in contact with its corresponding proximity switch. The distance between the two proximity switches and the sleeve is equal to the radius of the sector-shaped blade + 1-2 mm, ensuring that the sector-shaped blade can trigger the proximity switch to send a signal without damaging the proximity switch. During the rotation of the needle plate shaft, the sleeve can drive the sector plate to contact the proximity switch for a period of time. This time is the time required for the rotation angle of the needle plate shaft to equal the central angle of the sector plate.

[0041] In this embodiment, the sector 15 is configured as a semicircle, with two sector 15 arranged opposite each other. When the semicircular sector 15 rotates close to the proximity switch, the proximity switch sends an energizing signal.

[0042] The signal lines of both proximity switches 17 are connected to an AC contactor, which is connected to an electromagnetic clutch. Specifically, one proximity switch is connected to the first electromagnetic clutch via an AC contactor, and the other proximity switch is connected to the second electromagnetic clutch via another AC contactor, thereby controlling the movement of the first and second conveyor belts.

[0043] By using fan-shaped plates and proximity switches, the first and second conveyor belts operate alternately, so that when one conveyor belt is conveying chili peppers, the other conveyor belt stops conveying them.

[0044] When the first needle plate moves from top to bottom to punch holes, the first conveyor belt stops conveying; when the first needle plate moves from bottom to top, the first conveyor belt runs to convey. When the second needle plate moves from top to bottom to punch holes, the second conveyor belt stops conveying; when the second needle plate moves from bottom to top, the second conveyor belt runs to convey.

[0045] Both the first needle plate 6 and the second needle plate 7 have flat plates. The top of the flat plate is connected to the crank slider mechanism, and the bottom of the flat plate is connected to the punching needle, which punches holes in the chili peppers.

[0046] A pinhole plate can also be fixedly installed on the frame 1. The pinhole plate is set between the conveyor belt and the needle plate. The pinhole plate has pinholes corresponding to the punching needles of the needle plate. When the punching needles on the needle plate perform the punching action, they first pass through the pinhole plate and then punch the pepper. Due to the obstruction of the pinhole plate, when the needle plate completes its action and begins to move upward, it can prevent the pepper from moving upward with the punching needle.

[0047] In an optional implementation, protective edges are provided on both sides of the first conveyor belt and the second conveyor belt, and the protective edges are fixed to the frame to prevent the peppers from falling.

[0048] The working principle of this chili pepper punching machine is as follows:

[0049] When the machine is powered on, the first power unit drives the first conveyor belt to move via the first electromagnetic clutch and the first reducer; the second power unit drives the second conveyor belt to move via the second electromagnetic clutch and the second reducer; and the third power unit drives the first needle plate and the second needle plate to move up and down via the crank-slider mechanism.

[0050] Both the first and second conveyor belts feed chili peppers at the chili pepper feeding position, and then convey them to the chili pepper punching position where the chili pepper punching device punches holes.

[0051] When punching holes in chili peppers, if one of the sector-shaped plates on the needle plate shaft is not in contact with its corresponding proximity switch, the corresponding AC contactor de-energizes the first electromagnetic clutch, causing the first conveyor belt to stop rotating. At this time, the first crank-slider mechanism drives the first needle plate to move downwards from the highest point to perform the chili pepper punching operation. Simultaneously, the other sector-shaped plate on the needle plate shaft is in contact with its corresponding proximity switch, and the corresponding AC contactor energizes the second electromagnetic clutch, causing the second conveyor belt to rotate. At this time, the second crank-slider mechanism drives the second needle plate to move upwards from the lowest point after completing the chili pepper punching action.

[0052] When one of the sector-shaped plates on the needle plate shaft contacts its corresponding proximity switch, the corresponding AC contactor energizes the first electromagnetic clutch, causing the first conveyor belt to rotate. At this time, the first crank-slider mechanism drives the first needle plate to move upward from the lowest point to complete the chili pepper punching action. Simultaneously, when the other sector-shaped plate on the needle plate shaft does not contact its corresponding proximity switch, the corresponding AC contactor de-energizes the second electromagnetic clutch, causing the second conveyor belt to stop rotating. At this time, the second crank-slider mechanism drives the second needle plate to move downward from the highest point to perform the chili pepper punching operation.

[0053] After the peppers have been perforated, they can be sent to a storage device (such as a storage box) at the end of the two conveyor belts for storage.

[0054] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
