Description

Technical Field

[0001] This utility model relates to the technical field of sauce production equipment, specifically a sauce filling head with a cleaning structure. Background Technology

[0002] In the sauce production process, filling is a crucial step. The filling head is the executing component of the filling equipment, which comes into direct contact with the sauce. Currently, due to the high viscosity and solid particles of sauces, sauce filling heads on the market tend to accumulate residual sauce on the inner wall and outlet of the filling head during filling intervals or when the equipment is stopped. These residues gradually dry and solidify, not only wasting material but also clogging the discharge channel of the filling head, leading to inaccurate filling volume, material interruption, and leakage in subsequent processes.

[0003] Patent document CN219056724U discloses a sauce filling die head, which states that "This utility model discloses a sauce filling die head, including a shell, an upper fixed cavity, a through groove, and a lower fixed cavity. The upper and lower fixed cavities are respectively opened at the top and bottom of the shell. A through groove is provided between the upper and lower fixed cavities. A fixed chamber is provided at one end of the inner wall of the upper fixed cavity. A driven shaft is provided at the top of the fixed chamber through a rotating groove. A spiral pattern is provided around the driven shaft. The driven shaft passes through the through groove and its bottom end is located in the lower fixed cavity. A mounting plate is welded to one end of the shell near the top. A drive motor is mounted on the bottom of the mounting plate through a fixed seat. The power output end of the drive motor is connected to a drive gear. A driven gear is provided around the top of the driven shaft. This new invention has a stirring structure during material discharge, which can eliminate lumps in the sauce, thus preventing blockage of the die head and facilitating sauce filling. It is suitable for widespread use."

[0004] However, the cleaning technology for sauce filling molds in the aforementioned published literature has the drawbacks of being a single, passive method with blind spots, and it cannot achieve the technical problem of automated cleaning of high-viscosity sauce residues.

[0005] Therefore, it is necessary to develop a sauce filling head with a cleaning structure, which can improve the cleaning effect of the sauce filling head during use. Utility Model Content

[0006] The purpose of this invention is to provide a sauce filling head with a cleaning structure to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a sauce filling head with a cleaning structure, comprising a filling head body, wherein a cleaning structure is provided inside the filling head body, the cleaning structure comprising a fixed ring fixedly connected to the middle of the inner wall of the filling head body and a ring water pipe at the bottom, and two sets of first hydraulic cylinders with output ends facing opposite directions are fitted inside the fixed ring.

[0008] The output end of each of the first hydraulic cylinders is equipped with a metal ring, and a cleaning pad is fixedly connected to the outer wall of the metal ring;

[0009] A set of fixing plates is fixedly connected to the bottom of the inner wall of the filling head body. A mounting base is fixedly connected to one end of the fixing plate. A transmission component is provided inside the mounting base. The transmission component is used to drive the rotating shaft to rotate. Several spray holes are fitted into the outer wall of the rotating shaft. A rotary joint is connected to the bottom of the rotating shaft. A first external water pipe is fixedly connected to one side of the outer wall of the rotary joint.

[0010] Preferably, a servo motor is installed inside the mounting base, one end of which is connected to a power supply via a cable, and the power supply is fitted into the outer wall of the filling head body.

[0011] Preferably, the output end of the servo motor is equipped with a first helical gear, the outer wall of the first helical gear is meshed with a second helical gear, and the inner wall of the second helical gear is fixedly sleeved on the outer wall of the rotating shaft.

[0012] Preferably, a plurality of auxiliary cleaning rods are fixedly connected to the outer wall of the rotating shaft, and a cleaning brush is provided at one end of each auxiliary cleaning rod.

[0013] Preferably, the bottom of the filling head body is fixedly connected to a funnel outlet, and the top of the inner wall of the funnel outlet is fixedly connected to the outer wall of the annular water pipe.

[0014] Preferably, the bottom of the annular water pipe is provided with a plurality of fan-shaped nozzles, and the inside of the fan-shaped nozzles and the spray hole is provided with a one-way valve.

[0015] Preferably, the outer wall of the annular water pipe is provided with a second external water pipe.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model achieves efficient and thorough in-situ automatic cleaning by integrating mechanical scraping and rotary spraying into a coordinated cleaning mechanism. It can remove stubborn sauce residues from the inner wall of the filling head body without dead angles, significantly improving hygiene standards and effectively avoiding cross-contamination of products. This design greatly shortens the cleaning downtime between different batches of production, improves overall production efficiency, and extends the service life of the equipment through timely automated maintenance.

[0018] 2. This utility model further enhances the cleaning efficiency through a servo motor, helical gear transmission group, and auxiliary cleaning rod. The servo motor provides a precise and controllable power source, realizing stable rotation of the rotating shaft in multiple modes. The helical gear group efficiently transmits power, and the auxiliary cleaning rod on the rotating shaft violently disturbs the cleaning fluid during rotation, generating strong turbulence. This synergistic effect with the jet from the spray hole and the scraping of the cleaning pad greatly enhances the ability to disperse, dissolve, and flush away stubborn residues, ensuring thorough cleaning without dead angles. This raises the level of automated cleaning and hygiene standards of the filling head to a new level.

[0019] 3. This utility model uses a fan-shaped nozzle at the bottom of the circular water pipe to generate a wide-angle jet stream, which is specifically designed to efficiently rinse the inclined surface of the funnel outlet where sauce residue is most likely to remain, eliminating cleaning dead corners. All nozzles and spray holes are equipped with one-way valves to fundamentally prevent sauce or sewage from flowing back into the cleaning pipeline, strictly ensuring the purity of the medium and meeting the highest standards of food safety production. The independent second external water pipe allows the bottom cleaning ring to work in conjunction with or separately from the upper rinsing mechanism, realizing a complete, pollution-free, automated, and efficient cleaning of the filling head from the internal cavity to the discharge end, significantly improving the overall hygiene level and reliability of the equipment.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5According to one embodiment of this utility model, a sauce filling head with a cleaning structure includes a filling head body 1. The filling head body 1 is provided with a cleaning structure inside. The cleaning structure includes a fixed ring 2 fixedly connected to the middle of the inner wall of the filling head body 1 and a ring water pipe 3 at the bottom. Two sets of first hydraulic cylinders 4 with their output ends facing opposite directions are fitted inside the fixed ring 2. Each output end of the first hydraulic cylinder 4 is equipped with a metal ring 5. A cleaning pad 6 is fixedly connected to the outer wall of the metal ring 5. A set of fixed plates 7 is fixedly connected to the bottom of the inner wall of the filling head body 1. One end of the fixed plate 7 is fixedly connected to a mounting base 8. A transmission component is provided inside the mounting base 8. The transmission component is used to drive the rotating shaft 9 to rotate. A plurality of spray holes 10 are fitted into the outer wall of the rotating shaft 9. A rotary joint 11 is connected to the bottom of the rotating shaft 9. A first external water pipe 12 is fixedly connected to one side of the outer wall of the rotary joint 11.

[0030] Furthermore, at the start of the cleaning process, the sauce delivery valve is first closed to stop the supply of material to the filling head. The annular water pipe 3 is connected to the cleaning liquid or disinfectant supply pipe, and the first external water pipe 12 is connected to another cleaning liquid or disinfectant supply pipe via a rotary joint 11. A container is placed directly below the filling head to receive the waste liquid and residual sauce from the cleaning process. The valve connected to the first external water pipe 12 is opened, and the cleaning liquid or disinfectant enters the rotating shaft 9 through the rotary joint 11 and is ejected at high speed from several spray holes 10 on its outer wall. The transmission component inside the mounting base 8 is activated, which drives the rotating shaft 9 to start rotating. This allows the high-pressure cleaning fluid to cover the inner wall of the filling head 360° without dead angles. Then, the two sets of first hydraulic cylinders 4 are activated. The output end of the first hydraulic cylinder 4 pushes outward, driving the two metal rings 5 ​​and the cleaning pads 6 fixed on them to move up and down reciprocally. The cleaning pads 6 clean the inner wall of the filling head body 1. The rotating spray hole 10 uses cleaning fluid to impact the area scraped by the pads and the pads themselves, and washes away the scraped sauce. Thus, the process of "mechanical scraping + fluid flushing" is carried out simultaneously, and the cleaning efficiency is extremely high.

[0031] Please see Figure 2 and Figure 4 According to one embodiment of this utility model, a sauce filling head with a cleaning structure is provided. A servo motor 13 is provided inside the mounting base 8. One end of the servo motor 13 is connected to a power supply 14 via a cable. The power supply 14 is fitted into the outer wall of the filling head body 1. A first helical gear 15 is installed at the output end of the servo motor 13. A second helical gear 16 is meshed with the outer wall of the first helical gear 15. The inner wall of the second helical gear 16 is fixedly sleeved on the outer wall of the rotating shaft 9. A plurality of auxiliary cleaning rods 17 are fixedly connected to the outer wall of the rotating shaft 9. A cleaning brush 22 is provided at one end of the auxiliary cleaning rod 17.

[0032] Furthermore, the servo motor 13 is started, driving the first helical gear 15 at its output end to rotate. The rotation of the first helical gear 15 drives the second helical gear 16 meshing with it, thereby transmitting power to the rotating shaft 9, causing it to start rotating. The rotating shaft 9 drives the auxiliary cleaning rod 17 and the cleaning brush 22 on it to rotate at high speed. At this time, the cleaning brush 22 begins to scrub the inner wall of the fixed ring 2. The valve of the first external water pipe 12 is opened, and the cleaning liquid enters the rotating shaft 9 through the rotary joint 11 and is ejected from the spray hole 10 to all directions. Taking advantage of the variable speed of the servo motor 13, the servo motor 13 is controlled to run at low speed first and then at high speed to adapt to sauce residues of different viscosities. The servo motor 13 can also be set to run in forward or reverse alternately, which improves the scrubbing effect of the cleaning brush 22 and effectively prevents dirt from getting tangled on the brush, resulting in a more thorough cleaning.

[0033] Please see Figure 1 , Figure 2 and Figure 3 According to one embodiment of the present invention, a sauce filling head with a cleaning structure is provided. The bottom of the filling head body 1 is fixedly connected to a funnel outlet 18, and the top of the inner wall of the funnel outlet 18 is fixedly connected to the outer wall of the annular water pipe 3. The bottom of the annular water pipe 3 is provided with a plurality of fan-shaped nozzles 19. Both the fan-shaped nozzles 19 and the spray hole 10 are provided with a one-way valve 20. The outer wall of the annular water pipe 3 is provided with a second external water pipe 21.

[0034] Furthermore, a circular water pipe 3 with a fan-shaped nozzle 19 is installed at the top of the funnel outlet 18, forming a dedicated bottom cleaning ring. This ring extends the cleaning range from inside the filling head body 1 to the outlet area where sauce residue is most likely to remain. The fan-shaped nozzle 19 generates a wide-coverage fan-shaped jet stream, efficiently rinsing the inclined inner wall of the funnel outlet 18, ensuring that the sauce is completely flushed out and preventing it from drying out and accumulating, thus blocking the outlet. One-way valves 20 are installed inside both the fan-shaped nozzle 19 and the spray hole 10 of the rotating shaft 9. These valves strictly prevent sauce or dirty water in the filling head from flowing back into the clean cleaning water pipeline system due to negative pressure or gravity when a cleaning circuit is closed, thereby effectively preventing... To avoid cross-contamination between different media, the second external water pipe 21 provides an independent or parallel cleaning fluid channel to the bottom annular water pipe 3. It can work in conjunction with or in stages with the upper rotary jet cleaning. It can flexibly allocate the flow direction and pressure of cleaning water and disinfectant according to the actual contamination situation, so as to achieve optimal cleaning of different areas, effectively shorten the overall cleaning time and reduce the consumption of cleaning media. The annular water pipe 3 is directly set on the top of the inner wall of the funnel outlet 18. The structure is compact and does not interfere with the normal flow of sauce. The entire cleaning module is highly integrated with the filling head body 1, so that the cleaning of the outlet is also a link in the automated in-situ cleaning process, without the need for additional manual disassembly and cleaning.

[0035] Working principle: By integrating mechanical scraping and rotary spraying into a synergistic cleaning mechanism, efficient and thorough in-situ automatic cleaning is achieved. It can remove stubborn sauce residues from the inner wall of the filling head body 1 without any blind spots, significantly improving hygiene standards and effectively preventing cross-contamination of products. This design greatly shortens cleaning downtime between different batches, improving overall production efficiency. Simultaneously, timely automated maintenance extends the equipment's lifespan. The cleaning efficiency is further enhanced by the servo motor 13, helical gear transmission group, and auxiliary cleaning rod 17. The servo motor 13 provides a precise and controllable power source, enabling stable rotation of the rotating shaft 9 in multiple modes. Power is efficiently transmitted through the helical gear group. The auxiliary cleaning rod 17 on the rotating shaft 9 violently agitates the cleaning fluid during rotation, generating strong turbulence that interacts with the jet from the spray hole 10 and the scraping of the cleaning pad 6 to form a powerful cleaning effect. The synergistic effect greatly enhances the ability to break down, dissolve, and flush away stubborn residues, ensuring thorough cleaning without dead angles. This elevates the automation level and hygiene standards of the filling head to a new level. The fan-shaped nozzles 19 at the bottom of the circular water pipe 3 generate a wide-angle jet stream, specifically targeting the inclined surface of the funnel outlet 18, where sauce residue is most likely to remain, for efficient rinsing and eliminating cleaning dead angles. All nozzles and spray holes 10 are equipped with one-way valves 20, which fundamentally prevent sauce or wastewater from flowing back into the cleaning pipeline, strictly ensuring the purity of the medium and meeting the highest standards of food safety production. The independent second external water pipe 21 allows the bottom cleaning ring to work in conjunction with or separately from the upper rinsing mechanism, achieving full-process, pollution-free, automated, and efficient cleaning of the filling head from the internal cavity to the discharge end, significantly improving the overall hygiene level and reliability of the equipment.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
