Description

Technical Field

[0001] The present invention relates to the technical field of yogurt filling, in particular to a filling device and a method for high-viscosity yogurt. Background Art

[0002] Yogurt is a semi-fluid fermented dairy product with a mild sour taste due to its lactic acid content. It can help the human body better digest and absorb the nutrients in milk.

[0003] There are many existing technologies for yogurt filling devices, such as:

[0004] Chinese patent publication number CN214935950U discloses a filling device for active probiotic yogurt, including a support rod, a conveyor belt and a filling mechanism arranged on the top of the conveyor belt, the top of the support rod and the position of the top of the conveyor belt are fixedly connected to a mounting frame, and the inner wall of the mounting frame is installed with a partition structure; the partition structure includes a baffle, a driving motor, a No. 1 slide frame and a No. 2 slide frame, and the baffle is slidably connected between the No. 1 slide frame and the No. 2 slide frame; the utility model drives the motor, the rotating rod, the connecting rod and the slider to cooperate with the No. 1 slide frame, the No. 2 slide frame and the baffle. When the output shaft of the driving motor rotates, it can drive the rotating rod to perform circular motion, and the rotating rod can drive the slider to slide back and forth between the No. 1 slide frame and the No. 2 slide frame through the connecting rod. When the slider moves back and forth, it can drive the baffle to block the filling pipe on the filling mechanism, thereby effectively preventing the residual yogurt in the filling pipe from dripping onto the yogurt bottle.

[0005] However, there are still some problems in actual use:

[0006] When filling yogurt with an existing filling device, due to the viscosity of yogurt, the yogurt drips slowly during the filling process, and when the yogurt adheres to the wall of the filling port tube, the yogurt filling capacity in different filling bottles varies, affecting the filling quality. At the same time, when replenishing yogurt in the yogurt pot, the filling process usually needs to be stopped and the operator needs to inject yogurt into the yogurt pot, resulting in low production efficiency.

[0011] As a further improvement of the present technical solution, a tension spring is provided between the column and the sliding rod, and connecting holes are provided on the surface of the sealing plate. The connecting holes are arranged in a circular array, and the sealing plate is pulled away from the supply tank, so that the sealing plate and the connecting pipe are in an open state, allowing the yogurt inside the supply tank to flow into the yogurt pot through the connecting pipe.

[0012] As a further improvement of the present technical solution, the stirring assembly includes a rotating motor arranged on the top of the supply tank, the output end of the rotating motor passes through the supply tank and is provided with a connecting sleeve at the end, and a stirring rod is provided at the bottom of the connecting sleeve. The stirring rod is used to stir the yogurt contained in the supply tank to maintain the fluidity between the yogurt.

[0013] As a further improvement of this technical solution, the side wall of the connecting sleeve is provided with an extension arm, the end of the extension arm is provided with a groove, a scraper is provided for sliding in the groove, and an elastic part is provided in the scraper and the groove.

[0016] As a further improvement of the present technical solution, the scraping assembly includes a fixed bearing seat arranged at the bottom center of the filling port, a scraper is clamped inside the fixed bearing seat, the scraper is attached to the inner wall of the filling port, a worm gear is provided on the top of the scraper, a worm is provided on one side of the worm gear, and rotating gears are provided on both sides of the worm, and the rotating gears are provided on the side walls of the rack.

[0017] A second object of the present invention is to provide a filling method for high-viscosity yogurt, comprising the filling device for high-viscosity yogurt described in any one of the above, comprising the following steps:

[0018] S1. The piston rod at the end of the control cylinder drives the extrusion plate to move in the vertical direction. The extrusion plate squeezes and fills the yogurt inside the yogurt pot. The yogurt is squeezed against the milk leakage hole by the squeezing force. The long rod provided at the bottom of the milk leakage hole slides vertically on the inner wall of the hollow column and compresses the compression spring, so that the base plate moves away from the through hole on the surface of the filling port, and the yogurt leaks out through the milk leakage hole provided on the surface of the base plate;

[0019] S2. When the base plate is squeezed by the pressure and drives the long rod to slide on the inner wall of the hollow column, the rack at the bottom of the base plate drives the rotating gear to engage and rotate. When the rotating gear rotates, it drives the worm to rotate coaxially. When the worm rotates, it drives the worm wheel to engage and rotate. When the worm wheel rotates, it drives the scraper at its bottom to rotate on the inner wall of the filling port, thereby scraping the yogurt dripping on the inner wall of the filling port and causing it to fall into the filling bottle, thereby ensuring that the capacity of the filling bottle remains consistent during filling;

[0020] S3. The output end of the control cylinder drives the extrusion plate to slide against the inner wall of the yogurt pot. During this sliding process, the extrusion plate squeezes the yogurt inside the yogurt pot, causing the yogurt to flow from the filling port into the filling bottle below. During the yogurt filling process, the sealing plate seals the middle of the connecting tube. When the yogurt pot needs to be refilled, the cylinder drives the extrusion plate to move vertically upward. The extrusion plate creates negative pressure inside the yogurt pot. The pressure on the sealing plate drives the slide rod to slide against the inner wall of the connecting tube. During this sliding process, the extension spring stretches, opening the interior of the connecting tube. The yogurt inside the replenishment tank is then drawn by the vacuum force and flows along the connecting tube into the yogurt pot for replenishment.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. In the filling equipment for high-viscosity yogurt, the cylinder drives the extrusion plate to move upward in the vertical direction. The extrusion plate generates negative pressure inside the yogurt pot. Therefore, the sealing plate is subjected to pressure to drive the slide rod to slide on the inner wall of the connecting pipe. During the sliding process of the slide rod, the tension spring is stretched, so that the inside of the connecting pipe is in an open state. The yogurt inside the supply tank is affected by the vacuum suction force and flows along the inside of the connecting pipe to the inside of the yogurt pot for replenishment, thereby improving production efficiency.

[0023] 2. In the filling equipment for high-viscosity yogurt, the piston rod at the end of the cylinder is controlled to drive the extrusion disk to move in the vertical direction to squeeze and fill the yogurt inside the yogurt pot. The yogurt is squeezed against the milk leakage hole by the extrusion force, and the long rod provided at the bottom of the milk leakage hole slides along the vertical direction on the inner wall of the hollow column and squeezes the compression spring. The yogurt leaks out through the milk leakage hole opened on the surface of the base plate. When the piston rod at the end of the cylinder drives the extrusion disk to stop squeezing and filling the yogurt inside the yogurt pot, the long rod is driven by the reverse force of the compression spring to drive the base plate to move in the vertical direction, so that the top of the base plate blocks and seals the through hole on the surface of the filling port, and at the same time, the yogurt remaining on the surface of the base plate is squeezed and slides from the guide block to be filled, thereby improving the accuracy of the filling capacity.

[0024] 3. In the filling equipment for high-viscosity yogurt, when the base plate is subjected to the extrusion force and drives the long rod to slide on the inner wall of the hollow column, the rack provided at the bottom of the base plate drives the rotating gear to engage and rotate, and when the rotating gear rotates, it drives the worm to rotate coaxially, and when the worm rotates, it drives the worm wheel to engage and rotate, and when the worm wheel rotates, it drives the scraper provided at its bottom to rotate on the inner wall of the filling port, thereby scraping the yogurt dripping on the inner wall of the filling port and making it fall into the filling bottle, thereby ensuring that the capacity of the filling bottle remains consistent during filling.

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] like Figure 1As shown, one of the purposes of the present invention is to provide a filling device for high viscosity yogurt, see Figures 1-8 As shown, it includes a support frame 100, a servo motor 101 is provided on the top of the support frame 100, the output end of the servo motor 101 passes through the support frame 100 and is provided with a screw rod 102 at the end, a support plate 103 is provided on the surface of the screw rod 102, and when the screw rod 102 rotates, it drives the support plate 103 to move in the vertical direction, a yogurt pot 104 is provided at the center of the support plate 103, and the yogurt pot 104 is filled with high-viscosity yogurt, a cylinder 105 is provided on the top of the yogurt pot 104, a piston rod at the end of the cylinder 105 passes through the yogurt pot 104 and is provided with an extrusion disk 106 at the end, the extrusion disk 106 is in contact with the inner wall of the yogurt pot 104, a filling port 107 is provided at the bottom of the yogurt pot 104, and the surface of the support plate 103 is provided. A supply tank 200 is provided, and the supply tanks 200 are arranged in a row with the yogurt pot 104 as the center. The supply tank 200 and the yogurt pot 104 are connected by a connecting pipe 201. Spare yogurt is contained in the supply tank 200, and a stirring component 300 is provided inside the supply tank 200. The stirring component 300 is used to stir the spare yogurt. An injection component 400 is provided inside the filling port 107. The injection component 400 is used to automatically open and close when filling yogurt. A scraping component 500 is provided below the injection component 400. The scraping component 500 is used to scrape the inner wall of the filling port 107, so that the yogurt adhering to the inner wall of the filling port 107 falls into the filling bottle below the filling port 107.

[0041] Taking into account that it is necessary to frequently replenish yogurt in the yogurt pot 104 during filling, the filling process usually needs to be stopped and the operator needs to inject yogurt into the yogurt pot 104, resulting in low production efficiency. Therefore, the connecting pipe 201 is trapezoidal in shape, and a fixing block 202 is provided on the side of the connecting pipe 201 close to the supply tank 200. A column 203 is provided at the end of the fixing block 202. A sliding rod 204 is provided on the inner wall of the column 203 for sliding movement. A sealing plate 206 is provided at the end of the sliding rod 204. The middle part of the connecting pipe 201 is sealed by the sealing plate 206 to prevent the inside of the supply tank 200 from leaking. The spare yogurt is blocked, and a tension spring 205 is provided between the column 203 and the slide rod 204. The surface of the sealing plate 206 is provided with a connecting hole 207, and the connecting holes 207 are arranged in a circular array. Pull the sealing plate 206 to move away from the supply tank 200, so that the sealing plate 206 and the connecting pipe 201 are in an open state, so that the yogurt inside the supply tank 200 flows into the yogurt tank 104 through the connecting pipe 201. During the production process, the supply tank 200 is sealed, and the output end of the control cylinder 105 drives the extrusion plate 106 to slide on the inner wall of the yogurt tank 104. The extrusion plate 106 slides During the process, the yogurt inside the yogurt pot 104 is squeezed, and the yogurt flows into the filling bottle below from the filling port 107. During the yogurt filling process, the sealing plate 206 seals and blocks the middle of the connecting pipe 201. When the yogurt pot 104 needs to be replenished with yogurt, the cylinder 105 drives the squeezing plate 106 to move upward in the vertical direction. The squeezing plate 106 generates negative pressure inside the yogurt pot 104. Therefore, the sealing plate 206 is pressed to drive the sliding rod 204 to slide on the inner wall of the connecting pipe 201. During the sliding process of the sliding rod 204, the tension spring 205 is stretched, so that the inside of the connecting pipe 201 is open. In this state, the yogurt inside the supply tank 200 is subjected to the action of the vacuum suction force and flows along the inside of the connecting pipe 201 to the inside of the yogurt pot 104 for replenishment. Since the supply tanks 200 are arranged in a circular array outside the yogurt pot 104, bubbles are avoided when replenishing the yogurt pot 104, and the speed of yogurt replenishment is increased, thereby improving production efficiency. When the yogurt replenishment is completed, the suction force on the sealing plate 206 disappears, and the sliding rod 204 is driven by the force of the tension spring 205 to drive the sealing plate 206 to seal the inside of the connecting pipe 201, thereby blocking the flow of the spare yogurt inside the supply tank 200.

[0042] During the yogurt filling process, in order to maintain the uniformity of the ingredients in the yogurt, it needs to be stirred. Therefore, the stirring component 300 includes a rotating motor 301 arranged on the top of the supply tank 200. The output end of the rotating motor 301 passes through the supply tank 200 and is provided with a connecting shaft sleeve at the end. A stirring rod 302 is provided at the bottom of the connecting shaft sleeve. The stirring rod 302 is used to stir the yogurt contained in the supply tank 200. An extension arm 303 is provided on the side wall of the connecting shaft sleeve. A groove is provided at the end of the extension arm 303. A scraper 304 is slidingly provided in the groove. An elastic member 305 is provided in the scraper 304 and the groove. The scraper 304 is pressed against the inner wall of the supply tank 200 by the force of the elastic member 305. The output end of the rotating motor 301 is controlled to drive the stirring rod 302 to rotate, so that the stirring rod 302 stirs the yogurt inside the yogurt pot 104 evenly, thereby improving the mixing effect of the yogurt. Since high-viscosity yogurt has strong adhesion, part of the yogurt adheres to the inner wall of the yogurt pot 104, affecting the mixing effect. Therefore, when the output end of the rotating motor 301 drives the connecting sleeve to rotate, the extension arm 303 provided on the side wall of the connecting sleeve drives the scraper 304 to rotate. The scraper 304 is tightly fitted with the inner wall of the supply tank 200 by the force of the elastic member 305. When the scraper 304 rotates, it scrapes the yogurt attached to the inner wall of the supply tank 200, thereby improving the mixing efficiency of the yogurt.

[0043] In order to improve the filling accuracy during the filling process, the injection assembly 400 includes a hollow column 401 arranged inside the filling port 107, a long rod 402 is slidingly provided on the inner wall of the hollow column 401, a compression spring 403 is provided between the hollow column 401 and the long rod 402, a base plate 404 is provided on the top of the long rod 402, a groove is opened on the surface of the base plate 404, a guide block 406 is provided in the groove, and the top of the base plate 404 blocks the through hole on the surface of the filling port 107 in a natural state. The plug is sealed, a rack 407 is provided at the bottom of the base plate 404, and a scraping assembly 500 is provided on one side of the rack 407. When the rack 407 moves in the vertical direction, the scraping assembly 500 is driven to scrape the inner wall of the filling port 107. Due to the high viscosity of yogurt, the piston rod at the end of the cylinder 105 is controlled to drive the extrusion plate 106 to move. By controlling the moving height of the extrusion plate 106, the yogurt capacity can be accurately and quickly filled. When the yogurt in the yogurt pot 104 is squeezed and filled, the yogurt is squeezed against the milk leakage hole 405 by the squeezing force. The long rod 402 provided at the bottom of the milk leakage hole 405 slides along the inner wall of the hollow column 401 in the vertical direction and squeezes the compression spring 403. The yogurt leaks out through the milk leakage hole 405 provided on the surface of the base plate 404. Since the guide block 406 is provided on the surface of the milk leakage hole 405, the yogurt in the filling falls from the center of the filling port 107, which reduces the sticking of the yogurt. Attached to the inner wall of the filling port 107, when the piston rod at the end of the cylinder 105 drives the extrusion disk 106 to stop squeezing and filling the yogurt inside the yogurt pot 104, the long rod 402 is subjected to the reverse force of the compression spring 403 to drive the base plate 404 to move in the vertical direction, so that the top of the base plate 404 blocks and seals the through hole on the surface of the filling port 107, and at the same time, the yogurt remaining on the surface of the base plate 404 is squeezed and slides from the guide block 406 to be filled, thereby improving the accuracy of the filling capacity.

[0044] When yogurt drips onto the inner wall of the filling port 107 during filling, it is difficult to collect the yogurt due to its strong adhesion, which may easily lead to insufficient capacity of the filling bottle during filling. Therefore, a rack 407 is provided at the bottom of the base plate 404, and a scraping assembly 500 is provided on one side of the rack 407. When the rack 407 moves in the vertical direction, it drives the scraping assembly 500 to scrape the inner wall of the filling port 107. The scraping assembly 500 includes a fixed bearing seat 501 provided at the bottom center of the filling port 107, a scraper 502 is clamped inside the fixed bearing seat 501, and the scraper 502 is attached to the inner wall of the filling port 107. A worm gear 503 is provided on the top of the scraper 502, and a worm 504 is provided on one side of the worm gear 503. Rotating gears 505 are provided on both sides of 504, and the rotating gears 505 are provided on the side walls of the rack 407. During filling, when the base plate 404 is subjected to the extrusion force and drives the long rod 402 to slide on the inner wall of the hollow column 401, the rack 407 provided at the bottom of the base plate 404 drives the rotating gear 505 to engage and rotate. When the rotating gear 505 rotates, it drives the worm 504 to rotate coaxially. When the worm 504 rotates, it drives the worm wheel 503 to engage and rotate. When the worm wheel 503 rotates, it drives the scraper 502 provided at its bottom to rotate on the inner wall of the filling port 107, thereby scraping the yogurt dripping on the inner wall of the filling port 107 and making it fall into the filling bottle, thereby ensuring that the capacity of the filling bottle remains consistent during filling.

[0045] When in use, the piston rod at the end of the control cylinder 105 drives the extrusion plate 106 to move in the vertical direction to squeeze and fill the yogurt in the yogurt pot 104. The yogurt is squeezed against the milk leakage hole 405 by the squeezing force. The long rod 402 provided at the bottom of the milk leakage hole 405 slides vertically on the inner wall of the hollow column 401 and squeezes the compression spring 403. The yogurt leaks out through the milk leakage hole 405 on the surface of the base plate 404. Since the guide block 406 is provided on the surface of the milk leakage hole 405, the filling The yogurt falls from the center of the filling port 107. When the piston rod at the end of the cylinder 105 drives the extrusion plate 106 to stop squeezing and filling the yogurt in the yogurt pot 104, the long rod 402 is acted upon by the reverse force of the compression spring 403 to drive the base plate 404 to move in the vertical direction, so that the top of the base plate 404 blocks and seals the through hole on the surface of the filling port 107. At the same time, the yogurt remaining on the surface of the base plate 404 is squeezed and slides down the guide block 406 to be filled, thereby improving the accuracy of the filling capacity.

[0046] When the base plate 404 is squeezed by the force and drives the long rod 402 to slide on the inner wall of the hollow column 401, the rack 407 provided at the bottom of the base plate 404 drives the rotating gear 505 to engage and rotate. When the rotating gear 505 rotates, it drives the worm 504 to rotate coaxially. When the worm 504 rotates, it drives the worm wheel 503 to engage and rotate. When the worm wheel 503 rotates, it drives the scraper 502 provided at its bottom to rotate on the inner wall of the filling port 107, thereby scraping the yogurt dripping on the inner wall of the filling port 107 and causing it to fall into the filling bottle, thereby ensuring that the filling bottle capacity remains consistent during filling.

[0047] By controlling the output end of the cylinder 105, the extrusion plate 106 is driven to slide on the inner wall of the yogurt pot 104. During the sliding process of the extrusion plate 106, the yogurt inside the yogurt pot 104 is squeezed, and the yogurt flows into the filling bottle below from the filling port 107. During the yogurt filling process, the sealing plate 206 seals and blocks the middle of the connecting pipe 201. When the yogurt pot 104 needs to be replenished with yogurt, the cylinder 105 drives the extrusion plate 106 to move upward in the vertical direction. The extrusion plate 106 generates negative pressure inside the yogurt pot 104, so the sealing plate 206 06 The slide rod 204 is driven by pressure to slide on the inner wall of the connecting tube 201. During the sliding process of the slide rod 204, the tension spring 205 is stretched, so that the interior of the connecting tube 201 is in an open state. The yogurt inside the supply tank 200 flows along the inside of the connecting tube 201 to the inside of the yogurt pot 104 for replenishment due to the vacuum suction force. Since the supply tanks 200 are arranged in a circular array outside the yogurt pot 104, when the yogurt pot 104 is replenished with yogurt, bubbles are avoided, and the speed of yogurt replenishment is increased, thereby improving production efficiency.

[0048] A second object of the present invention is to provide a filling method for high-viscosity yogurt, comprising any one of the above-mentioned filling devices for high-viscosity yogurt, comprising the following steps:

[0049] S1. The piston rod at the end of the control cylinder 105 drives the extrusion plate 106 to move in the vertical direction. The extrusion plate 106 squeezes and fills the yogurt in the yogurt pot 104. The yogurt is squeezed against the milk leakage hole 405 by the squeezing force. The long rod 402 provided at the bottom of the milk leakage hole 405 slides in the vertical direction on the inner wall of the hollow column 401 and squeezes the compression spring 403, so that the base plate 404 is away from the through hole on the surface of the filling port 107, and the yogurt leaks out through the milk leakage hole 405 opened on the surface of the base plate 404;

[0050] S2. When the base plate 404 is squeezed and drives the long rod 402 to slide on the inner wall of the hollow column 401, the rack 407 provided at the bottom of the base plate 404 drives the rotating gear 505 to engage and rotate. When the rotating gear 505 rotates, it drives the worm 504 to rotate coaxially. When the worm 504 rotates, it drives the worm wheel 503 to engage and rotate. When the worm wheel 503 rotates, it drives the scraper 502 provided at its bottom to rotate on the inner wall of the filling port 107, thereby scraping the yogurt dripping on the inner wall of the filling port 107 and causing it to fall into the filling bottle, thereby ensuring that the filling bottle capacity remains consistent during filling;

[0051] S3, control the output end of the cylinder 105 to drive the extrusion plate 106 to slide on the inner wall of the yogurt pot 104. During the sliding process of the extrusion plate 106, the yogurt inside the yogurt pot 104 is squeezed, and the yogurt flows into the filling bottle below from the filling port 107. During the yogurt filling process, the sealing plate 206 seals and blocks the middle part of the connecting pipe 201. When the yogurt pot 104 needs to be replenished with yogurt, the cylinder 105 drives the extrusion plate 106 to move upward in the vertical direction. The extrusion plate 106 generates negative pressure inside the yogurt pot 104. Therefore, the sealing plate 206 is subjected to pressure to drive the slide rod 204 to slide on the inner wall of the connecting pipe 201. During the sliding process of the slide rod 204, the tension spring 205 is stretched, so that the interior of the connecting pipe 201 is in an open state. The yogurt inside the supply tank 200 flows along the inside of the connecting pipe 201 to the interior of the yogurt pot 104 for replenishment under the action of the vacuum suction force.
