Description

Technical Field

[0001] This invention relates to the field of food filling equipment technology, and specifically to a packaging device for preparing sour soup. Background Technology

[0002] Sour soup, a commonly used flavor condiment, typically requires quantitative injection into bottles, cans, and other containers after preparation to complete subsequent sealing and packaging processes. Conventional sour soup filling equipment generally includes a conveying mechanism, a filling head, and a transmission mechanism that drives the filling head to rise and fall. The conveying mechanism sequentially delivers empty containers to the filling station. The filling head descends and inserts into the container opening to inject the sour soup. After filling, the filling head rises back to its original position, and the filled container moves out with the conveying mechanism, allowing the next container to enter the station. This cycle achieves continuous filling.

[0003] However, during actual operation, the starting and stopping of the conveyor mechanism, container repositioning, and lifting and lowering of the filling head will all cause the equipment to vibrate to a certain extent. This vibration is especially noticeable under high-speed continuous filling conditions. Affected by this vibration, the residual acidic soup droplets at the end of the filling head are prone to shaking and detaching from the filling head, dripping onto the filling table below. This causes the table and the surrounding environment to be contaminated by acidic soup, which not only increases the workload of equipment cleaning and maintenance, but may also contaminate the outer wall of the filled containers, affecting the appearance and hygiene quality of the packaging. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention proposes a packaging device for preparing sour soup, which solves the technical problem that in actual operation, the starting and stopping of the conveyor mechanism, container repositioning, and the lifting and lowering of the filling head will all cause certain vibrations in the equipment. As a result, the residual sour soup droplets at the end of the filling head are prone to shaking and detaching from the filling head, dripping onto the filling table below, causing the table and the surrounding environment to be contaminated by sour soup.

[0005] The technical solution adopted in this invention is a packaging device for preparing sour soup, comprising: Preparation stage; The disc conveying mechanism includes a servo motor, a conveying disc, and an intermittent component. The servo motor is fixed inside the preparation table, and the conveying disc is rotatably mounted on the upper end of the preparation table. The conveying end of the servo motor is connected to the conveying disc via the intermittent component for intermittently driving the conveying disc to rotate and convey the container. A filling mechanism is used for filling containers. A storage box is used to temporarily store materials for the filling mechanism to extract them. The suction mechanism includes a suction tube and a suction assembly. The suction tube is connected between the filling mechanism and the storage tank. The suction assembly is installed between the suction tube and the storage tank. The suction assembly is drivenly connected to the output end of the intermittent assembly. When the conveyor disc rotates intermittently to convey the container, the suction assembly can perform suction operations on the residual material at the output port of the filling mechanism.

[0006] In a preferred embodiment, the intermittent component includes an active dial, a pin, and a driven grooved wheel. The active dial and the driven grooved wheel are both rotatably disposed inside the preparation table. The output end of the servo motor is drivenly connected to the active dial, the driven grooved wheel is drivenly connected to the conveyor plate, and the pin is fixed to the active dial and adapted to the driven grooved wheel.

[0007] In a preferred embodiment, the suction assembly includes a suction platform and a rotating disk. The suction platform is fixedly mounted on the upper end of the preparation platform, and a suction groove is formed in the middle of the suction platform. The rotating disk is rotatably disposed inside the suction groove. The rotating shaft of the conveying disk is connected to the rotating disk in a driving connection. A plurality of extrusion heads are evenly arranged on the outer circumference of the rotating disk. The suction tube is arranged in the middle of the inner side of the suction groove and is adapted to the plurality of extrusion heads of the rotating disk.

[0008] In a preferred embodiment, the suction mechanism further includes a transmission rod, a sealing head, and a sealing assembly. The transmission rod is rotatably mounted on the suction table and is connected to the active dial. The output end of the filling mechanism is provided with a sealing groove. The sealing head is slidably disposed inside the sealing groove. The transmission rod is connected to the sealing head via the sealing assembly, and is used to perform on / off operations at the output end of the filling mechanism.

[0009] In a preferred embodiment, the sealing assembly includes a cam fixed to the lower end of the transmission rod, and the arc-shaped side of the cam is connected to the end of the sealing head for driving the sealing head to reciprocate.

[0010] In a preferred embodiment, the sealing assembly further includes an adjusting block, two adjusting ears, and two adjusting wheels. The two adjusting ears are fixed at both ends of the adjusting block, one of which is fixedly connected to the sealing head. A sliding groove is provided in the middle of the adjusting block, and the sliding groove is horizontally slidably connected to the transmission rod. The two adjusting wheels are respectively rotatably disposed on the two adjusting ears, and both adjusting wheels are adapted to the arc-shaped side transmission of the cam.

[0011] In a preferred embodiment, an elastic arc plate is fixed to the adjusting lug near one end of the sealing head, the elastic arc plate being adapted to the shape of the container.

[0012] In a preferred embodiment, the filling mechanism includes a delivery pump and a filling head. The delivery pump is installed on the preparation table and communicates with the storage tank. The filling head is installed on the preparation table and communicates with the storage tank through the delivery pump. The sealing groove is formed in the filling head and is located above the suction tube connection.

[0013] In a preferred embodiment, the filling head is fixedly provided with a sealing tube communicating with the sealing groove, the sealing head and the sealing tube are slidably connected in a sealing manner, and a through groove communicating with the filling head is opened in the middle of the sealing head.

[0014] As can be seen from the above technical solution, the beneficial technical effects of the present invention are as follows: When in use, this equipment uses a servo motor and intermittent components to drive the conveyor plate to rotate intermittently and transport containers. At the same time, it also drives the suction component to operate synchronously. During the intermittent rotation of the conveyor plate to change the position of the container after filling, the suction component uses the suction pipe to suck the residual acid soup at the output port of the filling mechanism back to the storage tank. No additional power source is required to complete the suction and recycling of residual acid soup in sync with the conveying operation. This avoids the residual acid soup from dripping and contaminating the filling table and surrounding environment due to equipment vibration, reducing the workload of equipment cleaning and maintenance, and also prevents contamination of the outer wall of the filled containers, ensuring the appearance and hygiene quality of the packaging.

[0017] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0018] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0019] Example: like Figure 1 As shown, this embodiment provides a packaging device for preparing sour soup, including a preparation table 1, a disc conveying mechanism, a filling mechanism, a storage box 2, and a suction mechanism: The disc conveying mechanism includes a servo motor 11, a conveying disc 12, and an intermittent component. The servo motor 11 is fixed inside the preparation table 1, and the conveying disc 12 is rotatably mounted on the upper end of the preparation table 1. The conveying end of the servo motor 11 is connected to the conveying disc 12 through the intermittent component for intermittently driving the conveying disc 12 to rotate and convey the container; The filling mechanism is used to fill the container; The storage box 2 is used to temporarily store the material for the filling mechanism to extract the material; The suction mechanism includes a suction pipe 21 and a suction component. The suction pipe 21 is connected between the filling mechanism and the storage box 2, and the suction component is installed between the suction pipe 21 and the storage box 2. The suction component is connected to the output end of the intermittent component for transmission. When the conveying disc 12 intermittently rotates to convey the container, the suction component can perform suction operations on the residual material at the output port of the filling mechanism.

[0020] The sour soup material is pre-stored inside the storage box 2. The servo motor 11 outputs power to drive the conveyor plate 12 to rotate intermittently via the intermittent component. The conveyor plate 12 sequentially transfers empty containers to the lower station of the filling mechanism. When the conveyor plate 12 stops rotating and is in the filling station, the filling mechanism extracts the sour soup material from the storage box 2 and completes the filling operation of the container. After filling, the servo motor 11 drives the intermittent component to rotate, thereby switching the container station. At the same time, the output end of the intermittent component synchronously drives the suction component to run. The suction component uses the suction pipe 21 to suck up and recycle the residual sour soup material left at the outlet of the filling mechanism, preventing residual material from dripping and contaminating the equipment or container. The intermittent rotation of the conveyor plate 12 is coordinated with the suction action of the suction component to sequentially complete the entire set of operations of container conveying, filling, and suction of residual material at the filling outlet.

[0021] In one implementation, such as Figure 6 As shown, the intermittent assembly includes an active dial 13, a pin 131, and a driven grooved wheel 132. The active dial 13 and the driven grooved wheel 132 are both rotatably disposed inside the preparation table 1. The output end of the servo motor 11 is connected to the active dial 13 for transmission. The driven grooved wheel 132 is connected to the conveyor plate 12 for transmission. The pin 131 is fixed to the active dial 13 and is adapted to the driven grooved wheel 132.

[0022] The servo motor 11 outputs power to drive the active dial 13 to rotate continuously. The active dial 13 drives the pin 131 to rotate synchronously. When the pin 131 is embedded in the groove of the driven groove wheel 132, the pin 131 pushes the driven groove wheel 132 to rotate 90 degrees. The driven groove wheel 132 further drives the conveyor plate 12 to rotate synchronously by 90 degrees, completing the container transfer at the work station. After the pin 131 rotates out of the groove of the driven groove wheel 132, the drive constraint on the driven groove wheel 132 is released, and the driven groove wheel 132 and the conveyor plate 12 are then connected. The conveyor tray 12 then remains stationary and enters the filling operation station. As the active dial 13 continues to rotate, the pin 131 engages with the driven groove wheel 132 again, repeating the dialing action. This achieves intermittent start and stop operation of the conveyor tray 12 with each step of 90 degrees. At the same time, the rotation output of the active dial 13 synchronously provides transmission power to the suction component. During the period when the conveyor tray 12 rotates to change positions, it drives the suction component to carry out the residual material suction operation at the output port of the filling mechanism, thus realizing the coordinated operation of intermittent conveying and residual material suction in a cycle.

[0023] In one implementation, such as Figure 5As shown, the suction assembly includes a suction table 22 and a rotating wheel 23. The suction table 22 is fixed on the upper end of the preparation table 1. A suction groove is opened in the middle of the suction table 22. The rotating wheel 23 is rotatably disposed inside the suction groove. The rotating shaft of the conveying disc 12 is connected to the rotating wheel 23 for transmission. A plurality of extrusion heads 231 are evenly arranged on the outer circumference of the rotating wheel 23. The suction tube 21 is arranged in the middle of the side inside the suction groove and is adapted to the plurality of extrusion heads 231 of the rotating wheel 23.

[0024] The rotating shaft of the conveyor disc 12 drives the rotating wheel 23 to rotate synchronously. The rotating wheel 23 rotates inside the suction groove of the suction table 22. The extrusion head 231 on the outside of the rotating wheel 23 rolls and pushes the suction tube 21 arranged on the side of the suction groove in sequence, squeezing and pushing the tube cavity along the tube body direction, so that a negative pressure is formed inside the suction tube 21, and the suction of residual material at the outlet of the filling mechanism is completed. When the conveyor disc 12 completes a 90-degree step rotation and stops, the rotating wheel 23 stops rotating synchronously, the extrusion head 231 stops rolling and pushing the suction tube 21, and the suction assembly terminates the suction operation. When the conveyor disc 12 performs a 90-degree station switch again, the rotating wheel 23 rotates synchronously, and the extrusion head 231 repeats the action of rolling and pushing the suction tube 21, intermittently carrying out the suction of residual material.

[0025] In one implementation, such as Figure 2-4 As shown, the suction mechanism also includes a transmission rod 24, a sealing head 241, and a sealing assembly. The transmission rod 24 is rotatably mounted on the suction table 22 and is connected to the drive dial 13. The output end of the filling mechanism is provided with a sealing groove 242. The sealing head 241 is slidably and sealed inside the sealing groove 242. The transmission rod 24 is connected to the sealing head 241 through the sealing assembly and is used to perform on / off operations at the output end of the filling mechanism.

[0026] The active dial 13 and the transmission rod 24 rotate in a 1:1 ratio. The rotation of the active dial 13 drives the transmission rod 24 to rotate at a constant speed on the suction table 22. The transmission rod 24 drives the sealing head 241 through the sealing assembly to slide and seal inside the sealing groove 242 at the output end of the filling mechanism. When the conveyor plate 12 is in a stationary filling position, the transmission rod 24 drives the sealing head 241 to move, opening the output end of the filling mechanism and allowing normal downward discharge for filling containers. When the active dial 13 drives the grooved wheel mechanism to drive the conveyor... During the 90-degree switching of the conveyor tray 12, the transmission rod 24 rotates synchronously with the active dial 13 at the same speed. Through the sealing component, it drives the sealing head 241 to slide in the opposite direction, blocking and cutting off the output end of the filling mechanism. In conjunction with the suction mechanism, it sucks up the residual material at the output end. After the conveyor tray 12 completes the 90-degree step rotation and stops again, the transmission rod 24 is linked to release the sealing head 241, and the output end of the filling mechanism is restored to conduction. The cycle of switching the on and off of the filling output end is completed.

[0027] The sealing assembly includes a cam 25, which is fixed to the lower end of the transmission rod 24. The arc-shaped side of the cam 25 is connected to the end of the sealing head 241 for driving the sealing head 241 to reciprocate.

[0028] The transmission rod 24 drives the cam 25 to rotate together. The arc-shaped side of the cam 25 abuts against the end of the transmission sealing head 241, driving the sealing head 241 to slide back and forth in the sealing groove 242 at the output end of the filling mechanism. When the conveyor plate 12 is in the stationary filling position, the cam 25 rotates to the corresponding position, the sealing head 241 retracts, and the output end of the filling mechanism remains open, realizing normal material discharge and filling. During the period when the active dial 13 drives the grooved wheel mechanism to drive the conveyor plate 12 to switch positions by 90 degrees, the cam 25 rotates synchronously with the transmission rod 24. Its arc-shaped side pushes the sealing head 241 to slide forward, sealing the output end of the filling mechanism to cut off the material discharge and cooperate to complete the suction of residual material at the output end. After the conveyor plate 12 completes the 90-degree step rotation and returns to a stationary position, the cam 25 rotates to give way, the sealing head 241 resets and retracts, and the output end of the filling mechanism is open again. This cycle realizes the reciprocating on and off control of the filling output end.

[0029] The sealing assembly also includes an adjusting block 251, two adjusting ears 252 and two adjusting wheels 253. The two adjusting ears 252 are fixed at both ends of the adjusting block 251. One of the adjusting ears 252 is fixedly connected to the sealing head 241. A sliding groove 254 is provided in the middle of the adjusting block 251. The sliding groove 254 is horizontally slidably connected to the transmission rod 24. The two adjusting wheels 253 are respectively rotatably disposed on the two adjusting ears 252. Both adjusting wheels 253 are adapted to the arc-shaped side transmission of the cam 25.

[0030] The transmission rod 24 rotates synchronously with the active dial 13 at a 1:1 rotation ratio, driving the cam 25 to rotate as well. The cam 25 is configured with a 90-degree large circular segment, a 90-degree small circular segment, and two connecting arc segments of 90 degrees each. The cam 25 presses against two adjusting wheels 253 in sequence through its contour. The adjusting wheels 253 are rotatably mounted on the adjusting ears 252 at both ends of the adjusting block 251. The adjusting block 251 forms a horizontal sliding engagement with the transmission rod 24 through the sliding groove 254. The adjusting block 251 moves horizontally reciprocally driven by the cam contour, thereby driving the sealing head 241 fixed to it to slide and seal inside the sealing groove 242, realizing the opening and closing of the output end. When the cam 25 rotates to the area of ​​the connecting arc segment, it pushes the adjusting wheel 253 by the smooth contour of the connecting arc segment, driving the adjusting... Block 251, adjusting ear 252, and sealing head 241 move slowly, completing the slow opening and closing action of sealing head 241. Before entering the 90-degree push container station area corresponding to the large circular section, sealing head 241 has moved into place to achieve complete sealing. At this time, conveyor plate 12 starts to perform 90-degree station switching to push the container. The large circular section of cam 25 maintains the push against adjusting wheel 253, keeping sealing head 241 in a completely sealed state, and cooperates with suction mechanism to carry out residual material suction operation. After the station switching is completed, cam rotates to another set of connecting arc sections, driving sealing head 241 to slowly release the seal. The small circular section maintains the fully open state of sealing head 241, and the output end of filling mechanism is connected to carry out filling operation. The cycle repeats to complete the opening and closing control of filling output end.

[0031] An elastic arc plate 255 is fixedly provided on the adjusting lug 252 near the end of the sealing head 241. The elastic arc plate 255 is adapted to the shape of the container.

[0032] During the filling operation, the elastic arc plate 255 extends along with the adjusting ear 252 and, relying on its own elasticity, conforms to the shape of the container to laterally push and position the container on the conveyor tray 12, so that the container is aligned with the output end of the filling mechanism. After filling is completed, as the contour of the cam 25 changes, the adjusting block 251 retracts, and the elastic arc plate 255 moves away with the adjusting ear 252, releasing the limit on the container and avoiding interference with the subsequent 90-degree switching and transfer of containers on the conveyor tray 12. This cycle completes the positioning before filling and the avoidance action after filling.

[0033] Based on the above implementation methods, such as Figure 1-2 As shown, the filling mechanism includes a delivery pump 3 and a filling head 31. The delivery pump 3 is installed on the preparation table 1 and is connected to the storage tank 2. The filling head 31 is installed on the preparation table 1 and is connected to the storage tank 2 through the delivery pump 3. The sealing groove 242 is opened on the filling head 31 and is located above the connection of the suction tube 21.

[0034] When the conveying pump 3 starts, it continuously pumps the sour soup material inside the storage tank 2 into the filling head 31, completing the material supply. During the stationary phase of the filling station, the sealing head in the sealing groove 242 at the end of the filling head 31 opens and conducts, allowing the material to flow out from the lower end of the filling head 31, quantitatively filling the container positioned below. After filling, the sealing head 241 moves forward to seal the outlet of the filling head 31, cutting off the material flow. The sealing groove 242 is located above the connection position of the suction pipe 21. After sealing, the suction mechanism accurately sucks up the residual sour soup material below the sealing section of the filling head 31 through the suction pipe 21, preventing drip contamination. After the station switch is completed and the equipment re-enters the filling station, the sealing head 241 resets and opens, the filling head 31 is re-conducted, and the conveying pump 3 continues to supply material, completing the continuous filling operation in a cycle.

[0035] The filling head 31 is fixedly provided with a sealing tube 243 that communicates with the sealing groove 242. The sealing head 241 and the sealing tube 243 are slidably connected in a sealing manner. A through groove 2411 that communicates with the filling head 31 is opened in the middle of the sealing head 241.

[0036] The sealing head 241 slides inside the sealing tube 243 to achieve sealing. The passage is opened and closed by the through groove 2411 opened in the middle of the sealing head 241. When the through groove 2411 is aligned with the internal channel of the filling head 31, the material flows. When the through groove 2411 is misaligned, the material is cut off. The sealing tube 243 plays a radial restraint role on the sealing head 241 to prevent the sealing head 241 from generating pushing pressure at both ends.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
