Description

Technical Field

[0001] This application relates to the field of molding equipment, and more specifically, to a pet food production molding device with intelligent self-cleaning capabilities. Background Technology

[0002] The freshness-locking process for pet-friendly sausages is a core element in ensuring product quality, preserving nutritional value, and extending shelf life, and must be implemented throughout the entire process from raw material acceptance to finished product warehousing and logistics. This specification, based on the physiological digestive characteristics of pets and food safety requirements, integrates key technologies such as gentle processing, microbial inhibition, and environmental control to construct a standardized freshness-locking process system, ensuring that the product maintains its freshness, nutritional activity, and palatability throughout its shelf life.

[0003] After the raw materials are prepared, they usually need to be extruded under pressure and then packaged into vacuum bags. This step requires the use of molding production equipment. Currently, most mainstream equipment uses a spiral pressure continuous extrusion method to process the raw materials into cylindrical shapes. However, existing molding equipment generally has the problem of inconvenient internal cleaning. Especially when producing pet food with various ingredients, if the cleaning operation is cumbersome or not thorough, it is very easy to cause cross-contamination between different batches of raw materials. This will not only reduce the freshness of the pet food, but also seriously affect the quality of the product. Summary of the Invention

[0004] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes an intelligent self-cleaning pet food production and forming device that can disassemble the upper shell, lower shell, and rotating screw rod for individual cleaning. After cleaning, the upper shell, lower shell, and rotating screw rod can be dried separately. Furthermore, the entire cleaning process is mechanized, which facilitates cleaning while reducing cross-contamination between different batches of raw materials, thereby ensuring the freshness and quality of the pet food.

[0005] According to an embodiment of this application, a pet food production molding device with intelligent self-cleaning features includes a molding extrusion device. The molding extrusion device includes a housing, a rotating screw, a hopper, and a discharge nozzle. The rotating screw is located inside the housing. The housing includes an upper shell and a lower shell. The hopper is fixedly connected to the upper shell, and the discharge nozzle is threadedly connected to both the upper and lower shells. The device also includes a cleaning assembly, which includes a first lifting frame, a second lifting frame, a first linear guide rail, a horizontal rotating brush, a locking element, the second linear guide rail, the lifting rotating brush, and a lifting cleaning box. The lifting end of the first lifting frame is fixedly connected to the upper shell, and the lifting end of the second lifting frame is connected to the bottom of the lower shell. The first linear slide rail is fixedly connected to the rotating screw rod and the horizontal pushing rotating brush, respectively. The second linear slide rail is slidably connected to the lifting end of the first lifting frame. One side of the lifting rotating brush is fixedly connected to the sliding end of the second linear slide rail. The rotating end of the lifting rotating brush rotates and cleans the inside of the hopper. The horizontal pushing rotating brush rotates and cleans the inside of the upper shell and the lower shell, respectively. The lifting cleaning box is located on one side of the first linear slide rail. The sliding end of the first linear slide rail drives the rotating screw rod to move above the lifting cleaning box. The lifting end of the lifting cleaning box is raised, and the bottom of the rotating end of the rotating screw rod rotates inside the lifting cleaning box.

[0006] According to an embodiment of this application, a pet fresh food production molding device with intelligent self-cleaning features has the following advantages: During the use of the device, after a batch of pet fresh food sausages has been molded and filled, the cleaning process is initiated: First, the first lifting frame drives the upper shell to rise, and the second lifting frame drives the lower shell to fall, so that the rotating screw rod is fully open. Then, the sliding end of the first linear slide rail drives the rotating screw rod to move horizontally, moving the rotating end of the horizontally pushing rotating brush to the gap between the upper and lower shells. Next, the first lifting frame drives the upper shell to fall, and the second lifting frame drives the lower shell to rise, so that the upper and lower shells close and are fitted onto the outside of the horizontally pushing rotating brush. At the same time, the rotating screw rod moves horizontally to directly above the lifting cleaning box. During the cleaning stage, the lifting end of the lifting cleaning box rises upward, and cleaning water is injected into the box. The rotating screw rod starts rotating synchronously, completing its own cleaning inside the lifting cleaning box. At the same time, the horizontally pushing rotating brush starts rotating to clean the inner walls of the upper and lower shells. In addition, the sliding end of the second linear slide rail drives the lifting rotating brush to move horizontally, and the lifting end of the lifting rotating brush rises upward. The rotating end of the device is inserted into the inside of the hopper. External cleaning water is sprayed into the hopper through the rotating end of the lifting rotating brush. The water flows through the hopper into the cavity area between the upper and lower shells, working in conjunction with the horizontally pushing rotating brush to thoroughly clean the inner walls of the upper and lower shells. After cleaning, the upper shell is raised again and the lower shell is lowered again. The lifting end of the lifting cleaning box returns to its original position, and the sliding end of the first linear slide rail drives the horizontally pushing rotating brush to move out from between the upper and lower shells. At this time, the rotating screw rod does not move into the space between the upper and lower shells to allow for drying of the upper and lower shells and the rotating screw rod. When the device needs to be used again, simply move the rotating screw rod between the upper and lower shells and drive the upper and lower shells to close again to complete the device assembly. Throughout the entire usage cycle, the device can quickly and easily disassemble the upper and lower shells and the rotating screw rod, completing the comprehensive cleaning through mechanized operations. This not only provides convenience for the cleaning operation but also enhances the intelligence of the cleaning process, effectively reducing cross-contamination between different batches of raw materials, thereby ensuring the freshness of pet food and further ensuring product quality.

[0016] For different batches and different formulations of raw materials, the corresponding forming nozzles need to be replaced during production. However, in the current production process, the replacement of forming nozzles has a low degree of mechanization and relies heavily on manual operation. This is not only cumbersome but also inefficient, causing many inconveniences to the nozzle replacement work.

[0017] According to this application, a replacement component is also included, comprising a sliding member, a fifth motor, a drive shaft, a rotating frame, a seventh telescopic member, and a vertical frame. The sliding end of the sliding member is slidably connected to the bottom of the lifting end of the second lifting frame. The fifth motor is fixedly connected to the sliding end of the sliding member. A gear is provided at the output end of the fifth motor. A toothed ring is provided at the discharge nozzle, and multiple discharge nozzles of various specifications are provided. The discharge nozzle is rotatably connected to the rotating frame. The gear meshes with the toothed ring. The drive shaft is rotatably connected to the vertical frame. The rotating frame is sleeved outside the rotating end of the drive shaft. A connecting ring is provided on one side of the rotating frame and is rotatably connected to the rotating frame. The seventh telescopic member is fixedly connected to the vertical frame, and the output end of the seventh telescopic member is fixedly connected to the connecting ring. The replacement of the discharge nozzle is a fully mechanized operation. The specific operating procedure is as follows: During use, the sliding end of the sliding component first drives the fifth motor to move horizontally. The output end of the fifth motor synchronously drives the gear to rotate and moves together with the motor. By rotating the gear, the tooth position is adjusted so that the gear gradually meshes with the gear ring of the discharge nozzle. After the gear meshes with the gear ring, the fifth motor continues to drive the gear to rotate, driving the gear ring and the discharge nozzle to rotate synchronously through gear transmission. At the same time, the sliding end of the sliding component drives the fifth motor to move in the opposite direction, and the output end of the seventh telescopic component synchronously drives the rotating frame to move. Under the combined action of both, the old discharge nozzle, which was originally threaded to the outside of the upper and lower shells, is gradually disassembled, and the old discharge nozzle... After the nozzle is disassembled, the rotating end of the drive shaft starts, driving the rotating frame to rotate and transfer the new nozzle to be replaced to the installation position corresponding to the upper and lower shells. Then, the sliding end of the sliding part drives the fifth motor to move towards the new nozzle. The output end of the fifth motor continuously drives the gear to rotate, so that the gear and the gear ring of the new nozzle are precisely meshed again. Through the transmission action of the gear and the gear ring, the new nozzle is driven to rotate, and its threads are tightened to the outside of the upper and lower shells, completing the replacement of the nozzle. The entire replacement process realizes fully mechanized operation, effectively improving the mechanization of nozzle replacement, greatly reducing the intensity of manual operation, and providing great convenience for nozzle replacement work.

[0018] According to this application, the sliding member includes a ninth telescopic member and a seventh frame. The end of the ninth telescopic member is fixedly connected to the lifting end of the second lifting frame, the output end of the ninth telescopic member is fixedly connected to the seventh frame, the seventh frame is slidably connected to the lifting end of the second lifting frame, and the fifth motor is fixedly connected to the seventh frame.

[0019] According to this application, the drive shaft includes a sixth motor and a shaft body. The sixth motor is fixedly connected to the upright frame, the output end of the sixth motor is drivenly connected to the shaft body, the shaft body is rotatably connected to the upright frame, and the rotating frame is slidably sleeved on the outside of the shaft body.

[0020] Replaced forming nozzles need to be cleaned before being stored for reuse. The current common practice is to transfer the forming nozzles removed from the forming device to other dedicated cleaning equipment for cleaning. This method increases the investment cost of dedicated cleaning equipment, and the process of transferring and cleaning the nozzles is cumbersome, which affects production efficiency.

[0021] According to this application, a cleaning and drying assembly is also included, the cleaning and drying assembly comprising a third linear slide rail, a vertical plate frame, a rotating cleaning brush, a water tank, and a hot air component.

After the discharge nozzle is disassembled, the rotating end of the rotating frame starts to rotate, transferring the disassembled discharge nozzle to the side of the rotating cleaning brush. Then, the sliding end of the third linear slide rail starts to move horizontally, driving the upright frame to move synchronously. The upright frame synchronously drives the rotating cleaning brush, water tank and lower abutment to move together, so that the lower abutment moves to the upper position on the side of the discharge nozzle. The lower abutment moves downward and its bottom presses against the upper surface on the side of the discharge nozzle, achieving precise locking of the discharge nozzle. After locking, the rotating end of the rotating cleaning brush is inserted into the inside of the discharge nozzle. At the same time, the water tank moves to the bottom of the discharge nozzle to collect wastewater. External cleaning water is transported to the inside of the rotating cleaning brush through the pipeline and sprayed onto the inside of the discharge nozzle through the nozzle of the rotating cleaning brush. With the rotation of the rotating cleaning brush, the inside of the discharge nozzle is thoroughly cleaned. The cleaning wastewater is completely collected by the water tank. After the cleaning operation is completed, the hot air unit is activated, and its output end delivers heated and dry air to the inside of the rotating cleaning brush. The air is then blown onto the inside of the discharge nozzle through the nozzle of the rotating cleaning brush. Under the continuous rotation of the cleaning brush, the inside of the discharge nozzle is evenly dried. The whole process realizes the mechanized cleaning and drying of the discharge nozzle in one integrated operation, without the need for additional investment in special cleaning equipment.

Detailed Implementation

[0029] The following description, with reference to the accompanying drawings, describes an intelligent self-cleaning pet food production and forming apparatus according to an embodiment of this application.

[0030] like Figures 1-11As shown, an intelligent self-cleaning pet food production molding device according to an embodiment of this application includes a molding extrusion device 100. The molding extrusion device 100 includes a housing 110, a rotating screw 120, a hopper 130, and a discharge nozzle 140. The rotating screw 120 is located inside the housing 110. The housing 110 includes an upper shell 111 and a lower shell 112. The hopper 130 is fixedly connected to the upper shell 111. The discharge nozzle 140 is threadedly connected to the upper shell 111 and the lower shell 112 respectively. The device also includes a cleaning assembly 200.

[0031] The cleaning assembly 200 includes a first lifting frame 210, a second lifting frame 220, a first linear slide rail 230, a horizontal rotating brush 240, a locking element 260, a second linear slide rail 270, a lifting rotating brush 280, and a lifting cleaning box 290. The lifting end of the first lifting frame 210 is fixedly connected to the upper shell 111, and the lifting end of the second lifting frame 220 is fixedly connected to the bottom of the lower shell 112. The sliding end of the first linear slide rail 230 is rotatably connected to the rotating screw rod 120 and the horizontal rotating brush 240, respectively. The sliding end of the second linear slide rail 270 is connected to the first lifting frame 210. The lifting end is slidably connected, and one side of the lifting rotating brush 280 is fixedly connected to the sliding end of the second linear slide rail 270. The rotating end of the lifting rotating brush 280 rotates and cleans the inside of the hopper 130. The horizontally pushing rotating brush 240 rotates and cleans the inside of the upper shell 111 and the lower shell 112 respectively. The lifting cleaning box 290 is located on one side of the first linear slide rail 230. The sliding end of the first linear slide rail 230 drives the rotating screw rod 120 to move above the lifting cleaning box 290. The lifting end of the lifting cleaning box 290 is raised, and the bottom of the rotating end of the rotating screw rod 120 rotates inside the lifting cleaning box 290.

[0032] It should be noted that the freshness-locking process for pet food is as follows: raw material pretreatment must follow the principles of "low temperature, rapid processing, and minimal damage." Meat is thawed using 0-4℃ refrigerated thawing to avoid repeated freeze-thaw cycles that cause cell rupture and moisture loss. After thawing, the meat must be minced within 1 hour, with the temperature of the mincing equipment cavity controlled at ≤10℃ to prevent material stagnation and temperature rise. Fruits and vegetables are washed using 10-15℃ cold water to avoid high temperatures accelerating oxidation. After cutting, the food must proceed to the next process within 2 hours. Easily oxidized fruits and vegetables can be briefly soaked in natural antioxidant solutions such as vitamin C after cutting to reduce oxidative browning. Pre-treated raw materials must be covered with a vacuum cover or plastic wrap to maintain the corresponding preservation temperature and prevent excessive contact with air.

[0033] The working process of a pet food production and molding device with intelligent self-cleaning according to a specific embodiment of the present application is described below with reference to the accompanying drawings. Step 1: Molding preparation and raw material extrusion. First, the first lifting frame 210 and the second lifting frame 220 work together to drive the upper shell 111 and the lower shell 112 to close precisely. At this time, the sealing strip 113 of the lower shell 112 is inserted into the slot 114 of the upper shell 111 to ensure the sealing performance of the outer shell 110. At the same time, the locking rod 261 of the locking member 260 is locked into the third frame 221 under the elastic force of the tension spring 262 to achieve a stable lock between the upper shell 111 and the lower shell 112. Then, the pre-treated pet food raw materials are put into the hopper 130. The raw materials are guided by the hopper 130 into the rotating screw rod 120 area inside the outer shell 110. After the rotating screw rod 120 is started, it generates continuous pressure through the screw pushing action, and the raw materials are continuously extruded from the discharge nozzle 140 threaded to the outer shell 110 to complete the molding and filling operation of a single batch of pet food sausages. Step Two: Unlocking and Component Relocation Before Cleaning. After the single batch molding operation is completed, the cleaning preparation stage begins: The fourth telescopic component 263 of the locking component 260 is activated, driving the expansion rod 264 to push open the locking rod 261, releasing the locking state of the upper shell 111 and the lower shell 112. Then, the first telescopic component 213 of the first lifting frame 210 drives the first frame 211 to move upward, causing the upper shell 111 to rise. At the same time, the second telescopic component 223 of the second lifting frame 220 drives the third frame 221 to move downward, causing the lower shell 112 to descend, so that the internal rotating screw rod 120 is fully exposed. The first motor 231 of the first linear slide rail 230 starts, driving the first lead screw 232 to rotate, which in turn drives the sliding frame 233 to move horizontally, and then simultaneously drives the rotating screw rod 120 and the horizontal rotating brush 240 to move, moving the first brush head 241 of the horizontal rotating brush 240 to the gap between the upper shell 111 and the lower shell 112. At the same time, the first lifting frame 210 and the second lifting frame 220 work together again to drive the upper shell 111 and the lower shell 112 to close, so that the horizontal rotating brush 240 is fitted inside the shell, and the rotating screw rod 120 moves horizontally to the top of the lifting cleaning box 290. Step 3: Multi-component collaborative cleaning operation. After cleaning preparation is completed, each cleaning component starts synchronously: the sixth telescopic component 293 of the lifting cleaning box 290 drives the fifth frame 291 to move upward, causing the box 294 to rise, so that the bottom of the rotating spiral rod 120 is immersed in the pre-injected cleaning water inside the box. The rotating spiral rod 120 keeps rotating, and works with the brush rod 295 fixed inside the box to achieve its own comprehensive cleaning. At the same time, the third motor 243 of the horizontally pushing rotating brush 240 starts, driving the rotating shaft 242 to rotate, causing the first brush head 241 to rotate and clean the inner walls of the upper shell 111 and the lower shell 112. The third telescopic component 246 can push the square rod 244 back and forth through the crossbar 245, causing the first brush head 241 to extend and retract, expanding the cleaning range. At the same time, the second motor 271 of the second linear slide rail 270 drives the second filament... The lever 272 rotates, causing the first slider 273 to move horizontally, so that the lifting rotating brush 280 moves with the first slider 273 to directly below the hopper 130. The fifth telescopic component 287 of the lifting rotating brush 280 drives the first rod 281 and the second rod 282 to extend and retract, causing the fourth rod 284 to lift upward, inserting the second brush head 286 into the inside of the hopper 130. The fourth motor 285 drives the second brush head 286 to rotate and clean the inner wall of the hopper 130. External cleaning water is introduced into the second brush head 286 through the first water pipe 289 and the first connector 288, and sprayed out from the first spray hole 2861. The water flows through the hopper 130 into the cavity area between the upper shell 111 and the lower shell 112, and works with the horizontal rotating brush 240 to achieve a comprehensive rinsing of the inner wall of the shell. The wastewater generated by cleaning is discharged through the drain pipe with a valve on one side of the lifting cleaning box 290. Step 4: Post-cleaning reset and drying preparation.

At this time, the rotating screw rod 120 does not move into the inner cavity of the shell, so that the upper shell 111, the lower shell 112 and the rotating screw rod 120 are in an open state for natural drying. After drying, the rotating screw rod 120 is moved back into the shell through the first linear slide rail 230, and the upper shell 111 and the lower shell 112 are driven to close and lock, and the next batch of molding operation can begin.

[0044] For different batches and different formulations of raw materials, the corresponding forming nozzles need to be replaced during production. However, in the current production process, the replacement of forming nozzles has a low degree of mechanization and relies heavily on manual operation. This is not only cumbersome but also inefficient, causing many inconveniences to the nozzle replacement work.

[0045] According to this application, such as Figure 9 As shown, it also includes a replacement component 300, which includes a sliding member 310, a fifth motor 320, a drive shaft 330, a rotating frame 340, a seventh telescopic member 350, and a vertical frame 360. The sliding end of the sliding member 310 is slidably connected to the bottom of the lifting end of the second lifting frame 220. The fifth motor 320 is fixedly connected to the sliding end of the sliding member 310. A gear 321 is provided at the output end of the fifth motor 320, and a gear ring 141 is provided at the discharge nozzle 140. There are multiple and various specifications. The discharge nozzle 140 is rotatably connected to the rotating frame 340. The gear 321 is meshed with the gear ring 141. The drive shaft 330 is rotatably connected to the upright frame 360. The rotating frame 340 is sleeved on the outside of the rotating end of the drive shaft 330. A connecting ring 341 is provided on one side of the rotating frame 340. The connecting ring 341 is rotatably connected to the rotating frame 340. The seventh telescopic member 350 is fixedly connected to the upright frame 360. The output end of the seventh telescopic member 350 is fixedly connected to the connecting ring 341. When the replacement operation starts, the ninth telescopic component 311 of the sliding component 310 is activated first, driving the seventh frame 312 to slide along the bottom of the lifting end of the second lifting frame 220. The fifth motor 320, which is fixedly connected to the seventh frame 312, moves horizontally along with it. At the same time, the output end of the fifth motor 320 drives the gear 321 to rotate. The rotation of the gear 321 adjusts the tooth position, so that the gear 321 gradually and precisely meshes with the gear ring 141 of the discharge nozzle 140 currently installed on the outside of the upper shell 111 and the lower shell 112. After the gear 321 meshes with the gear ring 141, the fifth motor 320 continues to drive the gear 321 to rotate. The gear 321 drives the gear ring 141 and the discharge nozzle 140 to rotate synchronously. At the same time, the ninth telescopic component 311 drives the seventh frame 312 to drive the fifth motor 320 to move in the opposite direction. Simultaneously, the seventh telescopic component 350 fixed on the upright frame 360 ​​is activated, and its output end pushes the connecting ring 341 on one side of the rotating frame 340, causing the rotating frame 340 to move away from the shell. Under the combined action of the rotation and translation of the discharge nozzle 140, the old discharge nozzle 140, which was originally threaded to the outside of the upper shell 111 and the lower shell 112, is gradually unscrewed and disassembled. After disassembly, the old discharge nozzle 140 still remains attached to the rotating frame 340. In the rotating connection state, after the old discharge nozzle 140 is disassembled, the sixth motor 331 of the drive shaft 330 starts, and its output end drives the shaft 332 to rotate around the stand 360. The rotating frame 340, which is slidably sleeved on the outside of the shaft 332, rotates together with the shaft 332, transferring the new specification discharge nozzle 140, which is preset on the rotating frame 340 and adapted to the production needs of the next batch, to the installation position corresponding to the discharge port of the upper shell 111 and the lower shell 112. Then, the ninth telescopic component 311 drives the seventh frame 312 again to drive the fifth motor 320 to move in the direction of the new discharge nozzle 140. The fifth motor 320 continues to drive the gear. Rotation of 321 causes gear 321 to re-engage precisely with the gear ring 141 of the new discharge nozzle 140. Through the transmission action of gear 321 and gear ring 141, the new discharge nozzle 140 is driven to rotate. At the same time, the ninth telescopic component 311 drives the fifth motor 320 to move towards the housing, pushing the new discharge nozzle 140 to gradually approach and be threaded and fastened to the outside of the upper housing 111 and lower housing 112, completing the mechanized replacement of the discharge nozzle 140. The entire process is achieved through the precise linkage of each component of the replacement assembly 300, without the need for direct manual operation, realizing the efficient and convenient replacement of multiple specifications of discharge nozzles 140, and effectively improving production continuity.

[0046] According to this application, such as Figure 9 As shown, the sliding member 310 includes a ninth telescopic member 311 and a seventh frame 312. The end of the ninth telescopic member 311 is fixedly connected to the lifting end of the second lifting frame 220, the output end of the ninth telescopic member 311 is fixedly connected to the seventh frame 312, the seventh frame 312 is slidably connected to the lifting end of the second lifting frame 220, and the fifth motor 320 is fixedly connected to the seventh frame 312.

[0047] According to this application, such as Figure 9 As shown, the drive shaft 330 includes a sixth motor 331 and a shaft 332. The sixth motor 331 is fixedly connected to the support frame 360. The output end of the sixth motor 331 is connected to the shaft 332 in a transmission manner. The shaft 332 is rotatably connected to the support frame 360. The rotating frame 340 is slidably sleeved on the outside of the shaft 332.

[0048] Replaced forming nozzles need to be cleaned before being stored for reuse. The current common practice is to transfer the forming nozzles removed from the forming device to other dedicated cleaning equipment for cleaning. This method increases the investment cost of dedicated cleaning equipment, and the process of transferring and cleaning the nozzles is cumbersome, which affects production efficiency.

[0049] According to this application, such as Figure 10 and Figure 11 As shown, it also includes a cleaning and drying assembly 400, which includes a third linear slide rail 410, a vertical plate frame 420, a rotating cleaning brush 430, a water tank 440, and a hot air component 450. The sliding end of the third linear slide rail 410 is fixedly connected to the bottom of the vertical plate frame 420, the rotating end of the rotating cleaning brush 430 is rotatably connected to the upper part of the vertical plate frame 420, the water tank 440 is fixedly connected to one side of the vertical plate frame 420, the hot air component 450 is fixedly connected to one side of the vertical plate frame 420, the output end of the hot air component 450 is connected to the inside of the rotating cleaning brush 430, and the rotating cleaning brush 430 is inserted inside a discharge nozzle 140. After the discharge nozzle 140 is disassembled by the replacement component 300, the rotating end of the rotating frame 340 drives the discharge nozzle 140 to rotate and transfer to the side of the rotating cleaning brush 430, and the cleaning and drying operation is started. First, the seventh motor 411 of the third linear slide rail 410 starts, driving the seventh lead screw 412 to rotate, which drives the seventh slider 413 threaded to move horizontally. The upright plate frame 420 fixedly connected to the seventh slider 413 moves together. The upright plate frame 420 synchronously drives the rotating cleaning brush 430 installed on it. The water receiving tank 440 fixed on one side of the upright plate frame 420 and the lower abutment 421 set on the upper part move together, so that the lower abutment 421 moves accurately to the discharge nozzle. At the upper position on one side of 140, the eighth telescopic component 4211 of the lower abutment 421 is activated, driving the abutment block 4212 to move downward. The bottom of the abutment block 4212 tightly abuts against the upper surface of one side of the discharge nozzle 140, achieving precise positioning and locking of the discharge nozzle 140 to prevent displacement of the discharge nozzle 140 during the cleaning process. After locking, the upright frame 420 continues to drive the rotating cleaning brush 430 to move, so that the third brush head 432 of the rotating cleaning brush 430 is inserted into the inside of the discharge nozzle 140. At the same time, the water tank 440 moves synchronously to directly below the discharge nozzle 140 to collect the cleaning wastewater. At this time, the cleaning operation officially begins: external cleaning water flows through the second connector. Water is supplied through the second water pipe 429 to the inside of the third brush head 432. The water is then evenly sprayed onto the inner wall of the discharge nozzle 140 through the second spray hole 433 on the third brush head 432. Simultaneously, the eighth motor 431 of the cleaning brush 430 is activated, driving the third brush head 432 to rotate. Through the combined action of rotational friction and water flow, a thorough cleaning of the inside of the discharge nozzle 140 is completed. Wastewater generated during cleaning drips directly into the water collection tank 440 below for collection, preventing environmental pollution. After the cleaning operation is completed, the solenoid valve on the second water pipe 429 closes, stopping the water supply. Subsequently, the hot air unit 450 is activated, and the fan 451 sends air into the heating box 45. Heating is performed inside the nozzle 2. The heated dry air is delivered to the second water pipe 429 through the air duct 453, and then introduced into the third brush head 432. It is then blown towards the inside of the discharge nozzle 140 through the second spray hole 433. At the same time, the eighth motor 431 continuously drives the third brush head 432 to rotate, so that the dry air is evenly applied to all areas inside the discharge nozzle 140, achieving rapid and uniform air drying of the discharge nozzle 140. The entire process does not require manual intervention or additional special cleaning equipment. Through the precise linkage of the components within the assembly, the discharge nozzle 140 completes the integrated operation from positioning and locking, cleaning to air drying, effectively simplifying the nozzle processing flow, reducing equipment investment costs, and improving production efficiency.
