Description

Technical Field

[0001] The utility model relates to the technical field of vegetable processing devices, in particular to a dehydration device on a pickle production line. Background Art

[0002] Pickles are a beloved side dish. Making pickles requires a process called pickling. The salt in the pickles causes them to retain a high level of moisture. If the pickles are not dehydrated before being directly mixed or packaged, they can become salty, watery, and prone to flavor changes, affecting the final flavor. Traditionally, the pickles are placed in a pickling vat, pressurized with stones, and slowly dehydrated during the pickling process.

[0003] Existing patents CN201811294834.2, "A Salted Vegetable Desalting and Washing Device," and CN201721264299, "A Uniform and Efficient Desalting Machine," both use water to wash and desalinate salted vegetables after they have been pickled with a large amount of salt, and then remove the water. Washing removes some of the nutrients from the vegetables and diminishes the flavor of the pickled vegetables. Dehydration is also complex.

[0004] The existing patent 201520582830.X "A pickle dehydration device" uses an oil cylinder for extrusion, but due to the unreasonable material storage device in the device, there are problems in adding and taking out some materials that have been shredded and sliced.

[0005] The patents CN201921427326.7 "A squeeze dehydration device" and CN201922160136.X "A pickle squeeze dehydration device" previously applied for by the applicant also use external force and pressure for dehydration, but cannot be used on the production line.

[0006] The technical solution of the above patents usually requires a separate device for dehydration during the dehydration process, and after dehydration, the pickles need to be taken out and transported, which is not only troublesome but also easily causes the risk of contamination in the intermediate links of pickle production. Utility Model Content

[0007] Based on the above problems, the purpose of the utility model is to provide a dehydration device on a pickle production line, which can realize dehydration in the pickle production line. In conjunction with other existing equipment such as cleaning, cutting, weighing, and packaging on the production line, the pickled pickles can complete the entire processing process of cleaning, cutting, dehydration, stirring, weighing, and packaging in one go, and there is no need to take them out separately for dehydration in the middle.

[0008] In order to achieve the above purpose, the technical solution adopted by the utility model is: a dehydration device on a pickle production line, comprising: a roller installed on a frame, a conveyor belt installed around the roller, a side baffle, a discharge baffle, a pressure plate, a photoelectric material level sensor, a conveyor belt support plate, a second cylinder, a third cylinder, and a control unit, wherein:

[0009] The right end of the conveyor belt is the feed end, and the left end is the discharge end; a number of water leakage holes are opened on the conveyor belt, and two side baffles are respectively arranged on the front and rear sides of the conveyor belt and fixedly connected to the frame, and the side baffles are higher than the upper surface of the conveyor belt;

[0010] A vertical discharge baffle is movably arranged above the left end of the conveyor belt, the top end of the discharge baffle is fixedly connected to the tail end of the vertically arranged second cylinder piston rod, and the front and rear ends of the discharge baffle are respectively in contact with the inner side surfaces of the two side baffles; when the discharge baffle is lowered to the lowest position, its bottom edge is in contact with the conveyor belt;

[0015] The input end of the fixed control unit is connected to the output end of the photoelectric material level sensor, and the three output ends of the control unit are respectively connected to the coils of the second solenoid valve, the third solenoid valve and the AC contactor.

[0017] The utility model receives the signal of the photoelectric material level sensor through the control unit for processing and outputs the corresponding three-way control signal. Specifically, it is realized as follows: when the pickle material is accumulated to a certain height, the photoelectric material level sensor outputs a high-level signal, the AC contactor is powered off, the motor stops, the conveyor belt stops running, the third solenoid valve is energized, and the third cylinder drives the pressure plate to press down and dehydrate the pickle; when dehydration is completed after a preset time, the third solenoid valve is powered off, the third cylinder drives the pressure plate to lift, the second solenoid valve is powered off, the second cylinder drives the discharge baffle to lift, the AC contactor is energized, the motor resumes operation, the conveyor belt resumes operation to send the dehydrated pickle from the discharge end; after another preset time, the dehydrated pickle is sent out, the second solenoid valve is energized, the second cylinder drives the discharge baffle to descend to block the discharge end, and the new pickle is fed in and gradually re-accumulates to a certain height under the photoelectric material level sensor, and enters the pressurized dehydration stage again, starting a new round of cycle working process.

[0018] Furthermore, the third cylinder is fixedly mounted on the horizontal support plate, the front and rear ends of the horizontal support plate are respectively fixedly connected to the inner side surfaces of the two side baffles, and the piston rod of the third cylinder passes downward through the horizontal support plate.

[0019] Furthermore, the second cylinder is fixedly mounted on a vertical support mast fixedly connected to the frame.

[0020] Furthermore, the control unit includes a fixed first cylinder, a first solenoid valve, a reflective photoelectric sensor, and a control circuit box, wherein:

[0021] A reflective plate is fixedly connected to the tail end of the piston rod of the first cylinder. The positions of the first cylinder and the reflective photoelectric sensor are such that when the piston rod of the first cylinder is extended to its maximum stroke, the detection surface of the reflective photoelectric sensor faces the reflective plate. When the piston rod of the first cylinder is retracted, the detection surface of the reflective photoelectric sensor cannot receive a reflected signal from the reflective plate.

[0022] The first solenoid valve is connected to the air circuit of the first cylinder; it is used to realize the control of the cylinder by the solenoid valve, and the specific connection method of the air circuit of the solenoid valve and the cylinder is the existing conventional connection method;

[0026] The normally open contact of the second intermediate relay is connected to the coil of the third time relay, and the normally open contact of the third time relay is connected to the coil of the third solenoid valve.

[0027] In a specific implementation, the first cylinder and the reflective photoelectric sensor can be fixedly installed at any position as long as their relative positions meet the above requirements; the control circuit box and the first solenoid valve can also be fixedly installed at any position as long as the corresponding circuit connection can be achieved.

[0028] As a further preferred solution, the first solenoid valve, the second solenoid valve and the third solenoid valve are all fixedly installed on the outside of the side baffle.

[0029] As another further preferred solution, the first cylinder is fixedly mounted on a vertical support gantry fixedly connected to the frame through a connecting piece and is located near the front side of the frame. The height of the first cylinder is higher than the highest position of the pressure plate, and the reflective photoelectric sensor is fixedly mounted on the inner side of the front baffle.

[0030] Furthermore, the control circuit box is fixedly installed on the outside of the vertical support gantry.

[0031] Furthermore, a water receiving tray is provided. The water receiving tray is provided between the conveyor belt support plate and the belt below the conveyor belt and is fixedly connected to the frame. The water receiving tray is provided with a water outlet.

[0032] Furthermore, the photoelectric material level sensor is located at the right end of the pressure plate close to the front side of the frame. A triangular material stop block is also provided on the right side of the photoelectric material level sensor. The material stop block is fixedly installed on the inner side surface of the front baffle, with its inclined surface facing the feed end direction, and the bottom surface of the material stop block is in contact with the conveyor belt.

[0033] In this way, when feeding, new pickle material is blocked by the inclined surface of the material stop block and preferentially enters the area away from the photoelectric material level sensor. Then, blocked by the discharge baffle, the material gradually accumulates below the photoelectric material level sensor until the material below the photoelectric material level sensor reaches a sufficient height, causing the photoelectric material level sensor to output a high-level signal, ensuring that sufficient material is accumulated in the area below the pressure plate. Without this material stop block, the material may first enter the photoelectric material level sensor. When the total amount of material below the pressure plate is not enough, the material below the photoelectric material level sensor may have reached a certain height, causing the photoelectric material level sensor to output a high-level signal, starting the material pressing process, reducing work efficiency.

[0034] Furthermore, a flexible strip is fixedly mounted on the bottom edge of the discharge baffle, which can reduce friction between the discharge baffle and the conveyor belt and wear of components.

[0035] The beneficial effects of the utility model are:

[0036] The dehydration process can be realized in the pickle production line, which is suitable for the dehydration of pickles of various shapes. The pressure provided by the cylinder is used for pressurization, and the pressurization time can be flexibly adjusted by the setting of the control unit. A drainage tray is provided under the conveyor belt, and the dryness and wetness can be controlled. It is suitable for continuous production, has a reasonable structure, can reduce pollution, and is very suitable for the company's continuous production line. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] In this embodiment, the first solenoid valve YV1 , the second solenoid valve YV2 , and the third solenoid valve YV3 are all fixedly installed on the outer side of the side baffle 4 .

[0061] The specific working process and principle of this embodiment are as follows:

[0062] Preparation:

[0063] The first time relay KT1 is set to a delay time of t1, that is, after the coil is energized, its normally open contact is immediately closed and opens after a delay of t1; t1 is equal to the time the pressure plate 6 presses the pickles;

[0064] The second time relay KT2 is set with two sets of time t1 and t2, that is, after the coil is powered off, its normally open contact opens after a delay of t1 and then recloses after a delay of t2; the value of t2 is set so that all the pickled vegetables that have been dehydrated can be sent out from the discharge end;

[0065] The third time relay KT3 is also set with a delay time of t1, that is, its normally open contact closes immediately after the coil is energized and opens after a delay of t1;

[0066] The operation process is as follows:

[0067] (1) Feeding stage:

[0068] That is, in the initial stage of the operation of the conveyor belt 3 and feeding, there is no material below the photoelectric material level sensor 7 or the material height is insufficient, the photoelectric material level sensor 7 outputs a low level, the normally open contact of the first intermediate relay KA1 is in the disconnected state, the coil of the first time relay KT1 is de-energized, its normally open contact is in the disconnected state, the coil of the first solenoid valve YV1 is de-energized, the piston rod of the first cylinder 13 is in the retracted state, and the reflective photoelectric sensor 15 cannot receive the reflected signal from the reflective plate 14 and outputs a low level. Therefore, in this stage, the coil of the second intermediate relay KA2 is in the de-energized state, its normally closed contact is in the closed state, the coil of the second time relay KT2 is energized, its normally open contact remains closed, and the coil of the second solenoid valve YV2 is energized, so that the piston rod of the second cylinder 9 is in the extended to maximum stroke state, and the discharge baffle 5 is in the lowest position to block the material; at this time, the coil of the AC contactor KM is energized, so that the main circuit of the AC contactor KM is energized, the motor is in continuous operation, and the conveyor belt 3 continues to feed.

[0069] At the same time, since the coil of the second intermediate relay KA2 is in the power-off state, its normally open contact is disconnected, the coil of the third time relay KT3 is power-off and its normally open contact is in the disconnected state, and the coil of the third solenoid valve YV3 is in the power-off state, so that the piston rod of the third cylinder 11 is in the retracted state and the pressure plate 6 is in the raised position.

[0070] (2) Pressurized dehydration stage:

[0071] As the material is continuously fed, the material below the photoelectric level sensor 7 gradually accumulates to a certain height due to the discharge baffle 5 blocking the discharge end. The photoelectric level sensor 7 changes to output a high-level signal, so that the coil of the first intermediate relay KA1 is energized and its normally open contact is closed. The coil of the first time relay KT1 is energized and its normally open contact is also immediately closed (and then disconnected after a delay of t1). The coil of the first solenoid valve YV1 is energized, and the piston rod of the first cylinder 13 is extended to the maximum stroke, driving the reflector 14 to extend; the reflective photoelectric sensor 15 receives the reflected signal and outputs a high level, so that the second intermediate relay KA1 is energized and its normally open contact is closed. The coil of relay KA2 is energized and its normally closed contact is immediately disconnected, the coil of the second time relay KT2 is de-energized, and the normally open contact of the second time relay KT2 waits for the first set time t1 before disconnecting. Before its normally open contact is disconnected, the coil of the second solenoid valve YV2 remains energized, and the second cylinder 9 also keeps the piston rod extended, that is, the discharge baffle 5 is still in the lowest position to block the material; at this time, since the normally closed contact of the second intermediate relay KA2 is disconnected, the coil of the AC contactor KM is de-energized, causing the main circuit of the AC contactor KM to be de-energized, the motor stops running, and the conveyor belt 3 stops feeding.

[0072] At the same time, the coil of the second intermediate relay KA2 is energized and its normally open contact is immediately closed. The coil of the third time relay KT3 is energized and its normally open contact is also immediately closed (and then opens after a delay of t1). The coil of the third solenoid valve YV3 is energized, controlling the piston rod of the third cylinder 11 to extend, driving the pressure plate 6 to press down, and dehydrating the pickled vegetable material.

[0073] The conveyor belt support plate 8 supports the upper belt of the conveyor belt 3, and together with the pressure plate 6, realizes pressurized dehydration of the pickled vegetable material. The dehydrated water leaks out from the leakage hole 3a of the conveyor belt 3 and the through hole of the conveyor belt support plate 8 into the water receiving tray 16.

[0074] (3) The stage of sending out the dehydrated pickled vegetable materials:

[0075] After the delay reaches the set pressing time t1, the normally open contact of the third time relay KT3 is disconnected, the coil of the third solenoid valve YV3 is de-energized, the piston rod of the third cylinder 11 is retracted, and the pressure plate 6 is lifted.

[0076] At the same time, the second time relay KT2 reaches the first set time t1, the normally open contact is also disconnected, the coil of the second solenoid valve YV2 is de-energized, the piston rod of the second cylinder 9 is retracted, and the discharge baffle 5 is lifted.

[0077] The first time relay KT1 also reaches the set pressing time t1, the normally open contact is also disconnected, the coil of the first solenoid valve YV1 is de-energized, the piston rod of the first cylinder 13 retracts, and the reflective photoelectric sensor 15 outputs a low level, which de-energizes the coil of the second intermediate relay KA2 and closes its normally closed contact. The AC contactor KM coil is energized again, causing the motor to resume operation and the conveyor belt 3 to resume operation. As the conveyor belt 3 runs to the left end, the dehydrated pickled vegetable material is sent out from the discharge end.

[0078] (IV) Re-feeding stage:

[0079] After time t2, the dehydrated pickled vegetables are all discharged. After waiting for the second set time t2, the normally open contact of the second time relay KT2 recloses, energizing the coil of the second solenoid valve YV2, causing the piston rod of the second cylinder 9 to extend and the discharge baffle 5 to descend to its lowest position to block the subsequent pickled vegetables.

[0080] At this time, the coil of the second intermediate relay KA2 remains de-energized, with its normally open contact remaining open. The coil of the third time relay KT3 is de-energized, with its normally open contact remaining open. The coil of the third solenoid valve YV3 remains de-energized, causing the piston rod of the third cylinder 11 to remain retracted and the pressure plate 6 to remain raised. At the same time, because the normally closed contacts of the second intermediate relay KA2 remain closed, the coil of the AC contactor KM remains energized, and the motor remains running. The conveyor belt 3 continues to feed, and new pickle material is gradually delivered to the area below the pressure plate 6 until the material accumulates to a certain height again. The photoelectric level sensor 7 once again outputs a high-level signal, re-entering the pressurized dehydration stage and beginning a new cycle.
