Description

Technical Field

[0001] The present invention relates to the field of packaging machinery, and particularly to a hot sauce filling device. Background Art

[0002] In the industrial field, the operation objects of filling technology are generally liquids, and the vast majority of them are liquids with good fluidity, such as milk, beverages, and injectable drugs. Others include liquids with limited fluidity, such as yogurt, ice cream, and automotive grease. The fluidity of these filling objects is within the range that the filling technology can handle and has excellent aseptic or clean characteristics under the constraints of sanitary processes and production forms. Therefore, existing filling technologies can meet the filling requirements of such materials. With the all-round and multi-dimensional development of the agricultural industry, especially the agricultural food industry, into modernization, mechanization, and intelligentization, more and more agricultural and sideline products are obtained through industrial production methods, including traditional hot sauce. Hot sauce can be easily divided into fluid hot sauce and non-fluid hot sauce according to its particle size and water content. Fluid hot sauce can be industrially produced based on existing filling technologies, but non-fluid hot sauce, generally including hot sauce with a high solid content and low water content, cannot be industrially produced through existing filling technologies.

[0003] The reason is that there is a path for long-distance conveying of materials in existing filling technologies, and it is an inevitable structural feature. From the storage tank to the filling valve, a long conveying pipeline is required in the middle. Due to site constraints and the requirements for meeting sanitary grades, many auxiliary structures are often needed, making the existence of the conveying pipeline in the existing technology inevitable. Hot sauce with a high solid content is prone to accumulation during long-distance conveying, which may cause blockage. Therefore, existing filling technologies cannot fully apply to the filling operation of hot sauce. Summary of the Invention

[0004] Aiming at the defects of the above-mentioned existing linear filling technology, the present invention provides a hot sauce filling device, which can achieve the following technical effects: improving the design of the conveying structure between the storage tank and the filling valve, shortening the conveying path of hot sauce, preventing blockage caused by the accumulation of hot sauce, and making the filling device applicable to conveying hot sauce with a high solid content.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a chili sauce filling device, comprising a frame, a material storage component, and a quantitative extrusion component, the material storage component comprising a material storage tank, the frame is provided with a base, the material storage tank is installed on the base, and the bottom of the material storage tank is provided with a plurality of equally spaced discharge ports, the quantitative extrusion component comprises a filling valve, a first driving unit, and a second driving unit, the filling valve comprises a valve body, a rotary valve, and a piston, the valve body is provided with a feed port and a discharge port arranged up and down, the feed port and the discharge port are located in a vertical direction, the feed port is butt-joined with the discharge port and communicated, the rotary valve and the piston are arranged in the valve body, the rotary valve is provided with a connecting port and a accommodating cavity, the connecting port is communicated with the accommodating cavity, and the accommodating cavity opens toward one end of the piston, the first driving unit comprises a rotation driving unit and a translation driving unit, the rotation driving unit drives the rotary valve to rotate around a horizontal axis, when the rotary valve rotates, the connecting port is periodically communicated with the feed port and the discharge port, the translation driving unit drives the rotary valve to make a horizontal linear motion in the valve body, and the second driving unit drives the piston to make a horizontal linear motion in the valve body.

[0006] In the present technical solution, the hot sauce is stored in a storage tank, the valve body is arranged horizontally, the valve body is sealed and connected to the storage tank, the feed port is docked with the feed port, the feed port and the discharge port are arranged one above the other, and the two are located on the same circumference of the valve body. When the rotary drive unit drives the rotary valve to rotate, the connecting port also rotates along the circumference of the rotary valve. When the connecting port rotates to the upper side and docks with the feed port, the piston translates in the direction away from the rotary valve. Under the dual effects of suction and gravity, the hot sauce enters the accommodating cavity from the feed port, the feed port, and the connecting port. When the connecting port continues to rotate to the lower side and connects with the discharge port, the piston translates in the direction close to the rotary valve, so that the hot sauce flows out from the connecting port and the discharge port under the dual effects of pressure and gravity, and a conveying path for the hot sauce from the storage tank to the filling valve is established. In addition, the rotary valve can also translate in the horizontal direction in the valve body under the drive of the translation drive unit, thereby adjusting the channel size between the connecting port and the feed port and the discharge port, thereby controlling the flow rate of the hot sauce. The feed inlet and the discharge outlet are arranged in the vertical direction, and the translational movement of the rotary valve and the piston is in the horizontal direction, so that the conveying distance of the hot sauce is controlled within the inner diameter range of the valve body, thereby shortening the conveying path of the hot sauce and preventing the accumulation of the hot sauce from causing blockage.

[0007] Specifically, the rotation driving unit includes a first motor, a transmission rack, a driving rack, a load plate, and a main transmission rod. The first motor is fixed on the load plate. A first gear is provided on the output shaft of the first motor. The first motor drives the first gear to rotate in the horizontal plane. The transmission rack is connected to the driving rack, and the straight teeth of the transmission rack mesh with the first gear. The main transmission rod is rotatably arranged on the load plate through a bearing. The main transmission rod is arranged in the horizontal direction. A second gear is provided at one end of the main transmission rod. The driving rack meshes with the second gear. The other end of the main transmission rod is connected to the rotary valve. The first motor drives the driving rack to reciprocate horizontally, thereby driving the rotary valve to rotate around the horizontal axis. The translation driving unit includes a first cylinder, a first guide rod, and a first slider. One end of the first guide rod is fixed on the base through a bracket. The first cylinder is fixed on the bracket. The other end of the first guide rod is fixed on the part where the cylinder body is connected to the base. The piston rod of the first cylinder is connected to the first slider. The first slider is installed on the first guide rod in a sliding manner. The load plate is fixed on the first slider. The first cylinder drives the load plate to move linearly along the first guide rod and drives the rotary valve to move linearly in the valve body in the horizontal direction. With this setting, when the first motor drives the first gear to rotate, the transmission rack meshing with the first gear makes a translational movement. Since the driving rack and the transmission rack are fixedly connected, the driving rack will also make a translational movement. The second gear meshing with the driving rack rotates under the drive of the driving rack, thereby driving the main transmission rod to rotate around its own axis. Due to the connection relationship between the rotary valve and the main transmission rod, the rotary valve will rotate together with the main transmission rod. Therefore, when the first motor works, it can drive the rotary valve to rotate around the horizontal axis, so that the connection port is periodically communicated with the feed port and the discharge port, establishing a conveying path for the chili sauce. In addition, when the piston rod of the first cylinder extends and retracts, it can drive the first slider to slide on the first guide rod. Due to the connection relationship between the load plate and the slider and the main transmission rod being arranged on the load plate, the first cylinder can drive the rotary valve to translate horizontally in the valve body, controlling the channel size between the connection port and the feed port and the discharge port, that is, controlling the flow rate of the rotary valve.

[0008] Specifically, the second driving unit includes a second motor, a first transmission rod, a first swing rod, a first connecting rod, and a main piston rod. The second motor is installed on the base. The first transmission rod is connected to the output shaft of the second motor. The first swing rod is perpendicular to the first transmission rod. One end of the swing rod is fixed on the first transmission rod. The other end of the swing rod is hinged to one end of the connecting rod. The other end of the connecting rod is hinged to one end of the main piston rod. The other end of the main piston rod is connected to the piston. The second motor drives the main piston rod to make a linear reciprocating motion in the cylinder body. With this setting, a swing mechanism is provided between the second motor and the main piston rod. The second motor drives the first transmission rod to rotate, and then drives the first swing rod to swing. Through the transmission of the connecting rod, the main piston rod can slide back and forth in the valve body. The piston repeats the process of sucking in the chili sauce from the feed port and pressing out the chili sauce from the discharge port during the process of moving away from and approaching the rotary valve.

[0009] In addition, the chili sauce filling device further includes a drip collection component. The drip collection component includes a second cylinder, a second swing rod, a second connecting rod, a second guide rod, a second transmission rod, and a collection tank. The second cylinder is movably installed on the base. The piston rod of the second cylinder is hinged to the middle of the second swing rod. One end of the second swing rod is movably installed on the bracket through the second transmission rod. The other end of the second swing rod is hinged to one end of the second connecting rod. The other end of the second connecting rod is hinged to one end of the second guide rod. The second guide rod is installed on the carrier plate in a sliding manner. The collection tank is fixed to the other end of the second guide rod and is located below the discharge port. The second cylinder drives the second guide rod to perform a linear reciprocating motion in the horizontal direction on the carrier plate, thereby driving the collection tank to approach or move away from the discharge port. Through this setting, the second cylinder drives the second guide rod to slide on the carrier plate through a structure similar to the above-mentioned swing mechanism. Due to the connection relationship between the collection tank and the second guide rod, the collection tank will also perform a horizontal translation motion. The collection tank is located near the discharge port and the movement path passes directly below the discharge port. When the collection tank is directly below the discharge port, it can collect the material dripping from the discharge port during the filling pause interval.

[0010] In addition, the chili sauce filling device further includes a cleaning component. There is a cleaning port on the valve body. The cleaning port and the discharge port are both located on the lower side of the valve body. The cleaning component includes a lifting component and a reflux component. The reflux component includes two rows of reflux pipes. One row of reflux pipes is located below the discharge port, and a spring-based buffer structure is provided on this reflux pipe. The other row of reflux pipes is located below the cleaning port. The lifting component drives the reflux pipes to perform a linear motion in the vertical direction. Through this setting, during the cleaning operation, the piston disengages from the quantitative extrusion operation state, so that the valve body is not separated by the piston at the piston position, and the discharge port and the cleaning port are directly connected. After the carrier plate is pushed, the rotary valve enters the area where the piston was originally located, so that the inside of the storage tank is also connected to the two rows of reflux pipes. Then, a cleaning agent is injected into the storage tank, and the cleaning agent finally discharges from the reflux pipes. The reflux pipes also have a lifting function, which is used to raise the reflux pipes to dock with the discharge port and the cleaning port when cleaning is required, and lower the reflux pipes to disengage from the discharge port and the cleaning port when cleaning is not required.

[0011] Specifically, the lifting component includes a third motor, a third transmission rod, a third swing rod, a third connecting rod, a third guide rod, and a third slider. The third motor is installed on the frame. The third transmission rod is connected to the output shaft of the third motor. One end of the third swing rod is fixed on the third transmission rod, and the other end of the third swing rod is hinged to one end of the third connecting rod. The other end of the third connecting rod is hinged to the third slider. The third guide rod is fixed on the frame in a vertical state, and the third slider is installed on the third guide rod in a sliding manner. The return pipe is installed on the third slider, and the third motor drives the third slider to perform a linear motion in the vertical direction. With this setting, the third motor drives the third slider to slide up and down along the third guide rod through the above-mentioned similar swing mechanism. Since the return pipe is fixed on the third slider, the return pipe can be lifted and lowered under the drive of the third motor to dock with or separate from the discharge port and the cleaning port.

[0012] In order to be able to adjust the operating height of the storage tank, the base is arranged on the frame through a lifting unit. The lifting unit includes a driving motor and a lead screw. The driving motor is installed on the frame. The lead screw is arranged in the vertical direction and is connected to the output shaft of the driving motor. A lead screw sleeve is provided on the base, and the lead screw is movably connected to the lead screw sleeve. The driving motor drives the lead screw to rotate and drives the base to perform a linear reciprocating motion in the vertical direction along the lead screw.

[0013] In order to prevent the chili sauce from condensing in the storage tank, the storage component further includes a stirring component. The stirring component includes a stirring motor, stirring blades, and a transmission shaft. The stirring motor is fixed on the frame. The transmission shaft is rotatably connected to the storage tank. The stirring blades are arranged in the storage tank. One end of the transmission shaft is connected to the output shaft of the stirring motor, and the other end of the transmission shaft is connected to the stirring blades. The inside of the storage tank has an arc-shaped bottom surface, and the arc-shaped bottom surface matches the rotation range of the stirring blades. In this way, there will be no stirring dead corners or material accumulation at the bottom of the storage tank.

[0014] The advantages of the present invention are as follows: 1) The feeding port and the discharging port are arranged vertically, while the translational movements of the rotary valve and the piston are in the horizontal direction. When the rotary valve rotates, the connecting port is periodically communicated with the feeding port and the discharging port. The rotary valve can convey the chili sauce from the feeding port to the discharging port by rotating half a turn, controlling the conveying distance of the chili sauce within the inner diameter of the valve body, thereby shortening the conveying path of the chili sauce and preventing blockage caused by the accumulation of the chili sauce. 2) The second cylinder drives the second guide rod to slide on the loading plate through a swing mechanism. Due to the connection relationship between the collecting tank and the second guide rod, the collecting tank will also perform a translational movement in the horizontal direction. The collecting tank is located near the discharging port and the movement path passes directly below the discharging port. When the collecting tank is directly below the discharging port, it can collect the materials dripping from the discharging port during the pause of filling. 3) During the cleaning operation, the piston disengages from the quantitative extrusion operation state, so that the valve body is not separated by the piston at the piston position. The discharging port and the cleaning port are directly communicated. After the loading plate is pushed, the rotary valve enters the area where the piston was originally located. In this way, the inside of the storage tank is also communicated with the two rows of return pipes. Then, a cleaning agent is injected into the storage tank, and the cleaning agent finally discharges from the return pipes. The return pipes also have a lifting function, which is used to raise the return pipes to dock with the discharging port and the cleaning port when cleaning is required, and lower the return pipes to disengage from the discharging port and the cleaning port when cleaning is not required.

[0024] The present invention will be further described below with reference to the drawings of the specification and specific embodiments.

[0025] The first embodiment of the present invention:

[0026] As Figures 1 to 7 shown in, a chili sauce filling device includes a frame 100, a storage component, and a quantitative extrusion component.

[0027] The storage component includes a storage tank 200 and a stirring assembly. A base 101 is provided on the frame 100, the storage tank 200 is installed on the base 101, and a plurality of discharge ports 201 arranged at equal intervals are provided at the bottom of the storage tank 200.

[0028] The base 101 is arranged on the frame 100 through a lifting unit, and the lifting unit includes a driving motor 102 and a screw 103. The driving motor 102 is installed on the frame 100. Four screws 103 are arranged in a vertical direction and are connected to the output shaft of the driving motor 102 through a synchronous belt 104. A screw sleeve 105 is provided on the base 101, and the screw 103 is movably connected to the screw sleeve 105. The driving motor 102 drives the screw 103 to rotate and drives the base 101 to make a linear reciprocating motion in the vertical direction along the screw 103, so that the working height of the storage tank 200 can be adjusted.

[0029] The stirring assembly includes a stirring motor 202, a stirring blade 203, and a transmission shaft 204. The stirring motor 202 is fixed on the frame 100, the transmission shaft 204 is rotatably connected to the storage tank 200, the stirring blade 203 is arranged in the storage tank 200, one end of the transmission shaft 204 is connected to the output shaft of the stirring motor 202, and the other end of the transmission shaft 204 is connected to the stirring blade 203. The storage tank 200 has an arc-shaped bottom surface inside, and the arc-shaped bottom surface matches the rotation range of the stirring blade 203. In this way, there will be no stirring dead angle at the bottom of the storage tank 200, and no material will accumulate, thereby preventing the chili sauce from coagulating.

[0030] The quantitative extrusion component includes a filling valve 300, a first driving unit, and a second driving unit.

[0031] The filling valve 300 includes a valve body 301, a rotary valve 302, and a piston 303. The valve body 301 is provided with an inlet 304 and an outlet 305 arranged up and down. The inlet 304 and the outlet 305 are located in a vertical direction. The inlet 304 is connected to and communicated with the discharge port 201. The rotary valve 302 and the piston 303 are arranged in the valve body 301. The rotary valve 302 is provided with a connecting port 306 and a receiving chamber 307. The connecting port 306 is communicated with the receiving chamber 307. The receiving chamber 307 is opened toward one end of the piston 303, and the first driving unit includes a rotation driving unit and a translation driving unit. The rotation driving unit drives the rotary valve 302 to rotate around the horizontal axis. When the rotary valve 302 rotates, the connecting port 306 is periodically connected with the feed port 304 and the discharge port 305. The translation driving unit drives the rotary valve 302 to make a horizontal linear motion in the valve body 301, and the second driving unit drives the piston 303 to make a horizontal linear motion in the valve body 301.

[0032] The rotation drive unit includes a first motor 400, a transmission rack 401, a drive rack 402, a load plate 403, and a main transmission rod 404. The first motor 400 is fixed on the load plate 403. A first gear is provided on the output shaft of the first motor 400. The first motor 400 drives the first gear to rotate in the horizontal plane. The transmission rack 401 is connected to the drive rack 402. Both the drive rack 402 and the transmission rack 401 are straight plate-like structures. The length of the drive rack 402 is greater than that of the transmission rack 401. Straight teeth are provided on one side. The straight teeth of the transmission rack 401 face perpendicular to the straight teeth of the drive rack 402. The straight teeth of the transmission rack 401 face the horizontal direction, and the straight teeth of the drive rack 402 face downward. The straight teeth of the transmission rack 401 are engaged with the first gear. The main transmission rod 404 is rotatably arranged on the load plate 403 through a bearing. The main transmission rod 404 is arranged in the horizontal direction. A second gear is provided at one end of the main transmission rod 404. The drive rack 402 is engaged with the second gear. The other end of the main transmission rod 404 is connected to the rotary valve 302. The first motor 400 drives the drive rack 402 to reciprocate horizontally, thereby driving the rotary valve 302 to rotate around the horizontal axis.

[0033] The translation drive unit includes a first cylinder 500, a first guide rod 501, and a first slider 502. One end of the first guide rod 501 is fixed to the base 101 through a bracket 503. The first cylinder 500 is fixed to the bracket 503. The other end of the first guide rod 501 is fixed to the part where the cylinder body is connected to the base 101. The piston rod of the first cylinder 500 is connected to the first slider 502. The first slider 502 is mounted on the first guide rod 501 in a sliding manner. The load plate 403 is fixed to the first slider 502. The first cylinder 500 drives the load plate 403 to move linearly along the first guide rod 501 and drives the rotary valve 302 to move linearly in the horizontal direction within the valve body 301. When the first motor 400 drives the first gear to rotate, the transmission rack 401 engaged with the first gear makes a translational movement. Since the drive rack 402 and the transmission rack 401 are fixedly connected, the drive rack 402 also makes a translational movement. The second gear engaged with the drive rack 402 rotates under the drive of the drive rack 402, thereby driving the main transmission rod 404 to rotate around its own axis. Due to the connection relationship between the rotary valve 302 and the main transmission rod 404, the rotary valve 302 rotates together with the main transmission rod 404. Therefore, when the first motor 400 operates, it can drive the rotary valve 302 to rotate around the horizontal axis, so that the connection port 306 is periodically communicated with the feed port 304 and the discharge port 305, establishing a conveying path for the chili sauce. In addition, when the piston rod of the first cylinder 500 extends and retracts, it can drive the first slider 502 to slide on the first guide rod 501. Due to the connection relationship between the load plate 403 and the slider, and the main transmission rod 404 is arranged on the load plate 403, the first cylinder 500 can drive the rotary valve 302 to translate horizontally within the valve body 301, controlling the channel size between the connection port 306 and the feed port 304 and the discharge port 305, that is, controlling the flow rate of the rotary valve 302.

[0034] The second drive unit includes a second motor 600, a first transmission rod 601, a first swing rod 602, a first connecting rod 603, and a main piston rod 604. The second motor 600 is installed on the base 101. The first transmission rod 601 is connected to the output shaft of the second motor 600. The first swing rod 602 is perpendicular to the first transmission rod 601. One end of the swing rod is fixed to the first transmission rod 601, and the other end of the swing rod is hinged to one end of the connecting rod. The other end of the connecting rod is hinged to one end of the main piston rod 604. The other end of the main piston rod 604 is connected to the piston 303. The second motor 600 drives the main piston rod 604 to make a linear reciprocating motion within the cylinder body. There is a swing mechanism between the second motor 600 and the main piston rod 604. The second motor 600 drives the first transmission rod 601 to rotate, and then drives the first swing rod 602 to swing. Through the transmission of the connecting rod, the main piston rod 604 can slide back and forth within the valve body 301. The piston 303 repeats the process of sucking in the chili sauce from the feed port 304 and pressing out the chili sauce from the discharge port 305 during the process of moving away from and approaching the rotary valve 302.

[0035] In this technical solution, the chili sauce is stored in the storage tank 200. The valve body 301 is arranged horizontally and is hermetically connected to the storage tank 200. The material discharge port 201 is docked with the feed port 304. The feed port 304 and the discharge port 305 are arranged one above the other and are located on the same circumference of the valve body 301. When the rotary drive unit drives the rotary valve 302 to rotate, the connection port 306 also rotates circumferentially along the rotary valve 302. When the connection port 306 rotates to the upper side and is docked with the feed port 304, the piston 303 translates in a direction away from the rotary valve 302. The chili sauce enters the accommodation cavity 307 from the material discharge port 201, the feed port 304, and the connection port 306 under the dual action of suction and gravity. When the connection port 306 continues to rotate to the lower side and is communicated with the discharge port 305, the piston 303 translates in a direction close to the rotary valve 302, so that the chili sauce flows out from the connection port 306 and the discharge port 305 under the dual action of pressure and gravity, establishing a conveying path for the chili sauce from the storage tank 200 to the filling valve 300. In addition, the rotary valve 302 can also translate horizontally in the valve body 301 under the drive of the translation drive unit, so as to adjust the channel size between the connection port 306 and the feed port 304 and the discharge port 305, and further control the flow rate of the chili sauce. The feed port 304 and the discharge port 305 are arranged in the vertical direction, and at the same time, the translational movements of the rotary valve 302 and the piston 303 are in the horizontal direction, controlling the conveying distance of the chili sauce within the inner diameter range of the valve body 301, thereby shortening the conveying path of the chili sauce and preventing the chili sauce from accumulating and causing blockage.

[0036] The second embodiment of the present invention: Based on the structure of the above embodiment, as Figure 1 、 Figure 2 shown in, the chili sauce filling device in this embodiment further includes a drip collection component.

[0037] The drip collection component includes a second cylinder 700, a second swing rod 701, a second connecting rod 702, a second guide rod 703, a second transmission rod 704, and a collection trough 705. The second cylinder 700 is movably installed on the base 101. The piston rod of the second cylinder 700 is hinged to the middle of the second swing rod 701. One end of the second swing rod 701 is movably installed on the bracket 503 through the second transmission rod 704. The other end of the second swing rod 701 is hinged to one end of the second connecting rod 702. The other end of the second connecting rod 702 is hinged to one end of the second guide rod 703. The second guide rod 703 is installed on the load-carrying plate 403 in a sliding manner. The collection trough 705 is fixed to the other end of the second guide rod 703 and is located below the discharge port 305. The second cylinder 700 drives the second guide rod 703 to perform a linear reciprocating motion in the horizontal direction on the load-carrying plate 403, thereby driving the collection trough 705 to approach or move away from the discharge port 305. The second cylinder 700 drives the second guide rod 703 to slide on the load-carrying plate 403 through a swing mechanism. Due to the connection relationship between the collection trough 705 and the second guide rod 703, the collection trough 705 will also perform a horizontal translation motion. The collection trough 705 is located near the discharge port 305 and the movement path passes directly below the discharge port 305. When the collection trough 705 is directly below the discharge port 305, the material dripping from the discharge port 305 can be collected during the filling pause interval.

[0038] The third embodiment of the present invention: Based on the structure of the above embodiments, as Figure 2 , Figure 4 , Figure 7 shown, the chili sauce filling device in this embodiment further includes a cleaning component. The cleaning component includes a lifting assembly and a reflux assembly.

[0039] The reflux assembly includes two rows of reflux pipes 800. A cleaning port 308 is provided on the valve body 301. Both the cleaning port 308 and the discharge port 305 are located on the lower side of the valve body 301. One row of reflux pipes 800 is located below the discharge port 305. A buffer structure based on a spring is provided on this reflux pipe 800 to provide a buffer protection for the discharge port 305. The other row of reflux pipes 800 is located below the cleaning port 308. The lifting assembly drives the reflux pipes 800 to perform a linear motion in the vertical direction.

[0040] The lifting assembly includes a third motor 801, a third transmission rod 802, a third swing rod 803, a third connecting rod 804, a third guide rod 805, and a third slider 806. The third motor 801 is installed on the frame 100. The third transmission rod 802 is connected to the output shaft of the third motor 801. One end of the third swing rod 803 is fixed on the third transmission rod 802. The other end of the third swing rod 803 is hinged to one end of the third connecting rod 804. The other end of the third connecting rod 804 is hinged to the third slider 806. The third guide rod 805 is fixed on the frame 100 in a vertical state. The third slider 806 is installed on the third guide rod 805 in a sliding manner. The return pipe 800 is installed on the third slider 806. The third motor 801 drives the third slider 806 to perform a linear motion in the vertical direction. The third motor 801 drives the third slider 806 to slide up and down along the third guide rod 805 through a swing mechanism. Since the return pipe 800 is fixed on the third slider 806, the return pipe 800 can be lifted or lowered under the drive of the third motor 801 to dock with or separate from the discharge port 305 and the cleaning port 308.

[0041] During the cleaning operation, the piston 303 is disengaged from the quantitative extrusion operation state, so that the valve body 301 is not separated by the piston 303 at the piston 303. The discharge port 305 and the cleaning port 308 are directly connected. The rotary valve 302 enters the area where the piston 303 was originally located after the carrier plate 403 is pushed. In this way, the inside of the storage tank 200 is also connected to the two rows of return pipes 800. Then, a cleaning agent is injected into the storage tank 200, and the cleaning agent finally discharges from the return pipes 800. The return pipes 800 also have a lifting function, which is used to lift the return pipes 800 to dock with the discharge port 305 and the cleaning port 308 when cleaning is required, and lower the return pipes 800 to separate them from the discharge port 305 and the cleaning port 308 when cleaning is not required.

[0042] The specific description of the present invention in the above embodiments is only for further explaining the present invention and cannot be understood as a limitation on the protection scope of the present invention. Any non-essential improvements and adjustments made by those skilled in the art based on the content of the above invention fall within the protection scope of the present invention.
