Description

Technical Field

[0001] This utility model relates to a food processing machine, specifically to a hopper opening and closing mechanism for a supermarket food processing machine for near-expiry or expired food. Background Technology

[0002] In the daily operation of supermarkets, a large number of near-expiry and expired foods are generated. These foods need to be processed in a timely manner to prevent them from entering the market and causing food safety hazards. At present, supermarkets usually use food processing machines to crush and destroy near-expiry and expired foods. As the feeding component of the food processing machine, the performance of the opening and closing mechanism of the hopper directly affects the processing efficiency and the user experience of the equipment.

[0003] The existing hopper opening and closing mechanisms of supermarket near-expiry food processing machines have the following shortcomings: First, the hopper lid opening and closing are mostly driven by a single power source, which is prone to uneven force distribution leading to jamming during opening and closing. Furthermore, the lack of a buffer structure results in a large impact force when closing, easily causing damage to equipment components. Second, food in the hopper cavity is prone to bridging and blockage due to moisture and stickiness, leading to poor feeding and affecting processing efficiency. Third, cleaning the hopper after use is inconvenient; manual cleaning is labor-intensive and incomplete, and residual food residue easily breeds bacteria, causing secondary contamination. Fourth, moisture easily remains in the hopper cavity after cleaning; if not dried promptly, it will accelerate equipment corrosion and shorten its service life. Therefore, there is an urgent need for a hopper opening and closing mechanism that can solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a hopper opening and closing mechanism for a supermarket near-expiry food processing machine. This mechanism enables the smooth opening and closing of the hopper cover, prevents hopper blockage, facilitates cleaning and drying, and improves the overall performance of the equipment.

[0005] To solve the above-mentioned technical problems, this utility model achieves the following solution: The hopper opening and closing mechanism of a supermarket near-expiry food processing machine of this utility model includes: The hopper body has a hopper cavity; The bin cover is rotatably mounted on the upper end of the hopper cavity, and the upper end of the hopper cavity can be opened and closed by opening and closing the bin cover; The first power unit has a first end hinged to the hopper body and a second end hinged to the bin cover. The first power unit can drive the bin cover to open and close. The material pushing and arch breaking device is obliquely mounted on the hopper body. It has a second power unit and a push block driven and connected to the second power unit. The push block is driven to perform a reciprocating motion and can enter the hopper cavity after being driven. The cleaning unit includes a nozzle installed on the cover surface of the compartment cover and a flexible pipe located on the back of the compartment cover and connected to the nozzle. A buffer mechanism is connected between the bin cover and the hopper body; The drying section includes a heater located at the upper edge of the hopper body, an air duct connected to the heater and extending into the hopper cavity, and an air nozzle installed at the end of the air duct.

[0006] Furthermore, the lower end of the hopper body is the discharge port, which is smaller than the upper end of the hopper cavity.

[0007] Furthermore, the bin cover is connected to the upper end of the hopper cavity via a hinge.

[0008] Furthermore, the first power unit is provided in two sets, and the two sets of first power units are symmetrically installed on both sides of the hopper body. The first power unit is a first cylinder.

[0009] Furthermore, the second power unit is a second cylinder.

[0010] Furthermore, the nozzle has a rotating structure that automatically rotates when spraying water, and the nozzle has nozzles in multiple directions.

[0011] Furthermore, the buffer mechanism is a third cylinder, the first end of which is hinged to the bin cover and the second end of which is hinged to the hopper body.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The opening and closing of the silo cover of this utility model is smooth and reliable: two sets of symmetrically arranged first cylinders are used as the power unit to drive the opening and closing of the silo cover, ensuring that the silo cover is subjected to uniform force and avoiding jamming; at the same time, a third cylinder is set as a buffer mechanism to reduce the impact force when the silo cover is closed, protect the equipment components, and improve the safety and stability of use.

[0013] 2. This utility model prevents hopper cavity blockage: The inclined pusher and arch-breaking device is driven by the second cylinder to reciprocate within the hopper cavity, which can effectively break up the bridging blockage caused by factors such as moisture and stickiness of food, ensuring smooth feeding and improving food processing efficiency.

[0014] 3. This utility model offers convenient and thorough cleaning: The rotating multi-directional spray nozzles on the lid, combined with the flexible pipeline connection to the water supply system, enable all-round automatic spray cleaning of the hopper cavity, eliminating the need for manual cleaning, reducing labor intensity, and ensuring more thorough cleaning while preventing residual food from breeding bacteria.

[0015] 4. This utility model provides rapid drying and moisture prevention: The drying section at the upper edge of the hopper body blows hot air into the hopper cavity through a heater, air duct, and air nozzle, which can quickly dry the hopper cavity after cleaning, prevent moisture residue from causing equipment corrosion, extend the service life of the equipment, and keep the hopper cavity dry and clean.

[0023] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] Example 1: The specific structure of this utility model is as follows: Please refer to the appendix. Figure 1-3The present invention relates to a hopper opening and closing mechanism for a supermarket near-expiry food processing machine, wherein the hopper opening and closing mechanism 2 includes: The hopper body 24 has a hopper cavity; The bin cover 21 is rotatably mounted on the upper end of the hopper cavity, and the upper end of the hopper cavity can be opened and closed by opening and closing the bin cover 21; The first power unit 25 has a first end hinged to the hopper body 24 and a second end hinged to the bin cover 21. The first power unit 25 can drive the bin cover 21 to open and close. The material pushing and arch breaking device 22 is obliquely mounted on the hopper body 24. It has a second power unit 222 and a push block that is driven and connected to the second power unit 222. The push block is driven to perform a reciprocating motion and can enter the hopper cavity after being driven. The cleaning unit includes a nozzle 23 installed on the cover of the compartment cover 21 and a flexible pipe located on the back of the compartment cover 21 and connected to the nozzle 23; the flexible pipe is connected to a water tank 7 through a water pipe, and the water tank 7 is equipped with a water pump. The buffer mechanism 26 is connected between the bin cover 21 and the hopper body 24; The drying section includes a heater 27 located at the upper edge of the hopper body 24, and an air duct connected to the heater 27 with its outer end extending into the hopper cavity. An air nozzle 28 is installed at the end of the air duct. The heater 27 is connected to a hot air blower 8 via a pipe, and the hot air blower 8 is connected to an air compressor 9 via a pipe.

[0025] The lower end of the hopper body 24 is the discharge port 241, which is smaller than the upper end of the hopper cavity.

[0026] The cover 21 is connected to the upper end of the hopper cavity via a hinge.

[0027] The first power unit 25 is provided in two sets, and the two sets of first power units 25 are symmetrically installed on both sides of the hopper body 24. The first power unit 25 is a first cylinder.

[0028] The second power unit 222 is the second cylinder.

[0029] The nozzle 23 has a rotating structure that automatically rotates when spraying water, and the nozzle 23 has nozzles in multiple directions.

[0030] The buffer mechanism 26 is a third cylinder, the first end of which is hinged to the bin cover 21 and the second end of which is hinged to the hopper body 24. Example 2:

[0031] like Figure 4-5 As shown, Figure 4This is a first-view perspective perspective view of the hopper opening and closing mechanism of this utility model installed on a food processing machine. Figure 5 This is a second-view perspective perspective view of the hopper opening and closing mechanism of this utility model installed on a food processing machine.

[0032] The hopper opening and closing mechanism 2 of this utility model is installed on the top of the frame 3. One side of the frame 3 is the elevator 1, which is used to lift the bracket. The bracket is used to fix the garbage can. The garbage can containing near-expiry or expired food is lifted to the highest point and flipped so that the near-expiry or expired food is poured into the opened hopper cavity.

[0033] Below the hopper opening and closing mechanism 2 is a gate valve, which is used to open and close the discharge port 241 of the hopper body 24. The gate valve is equipped with a sewage interface.

[0034] Below the gate valve is the crusher 4 installed on the frame 3. Near-expiry or expired food enters the crusher 4 through the hopper for crushing and processing. The crushed food enters the receiving hopper 6 below the crusher 4.

[0035] A filter box 5 is installed adjacent to the frame 3. The filter box 5 is used to filter sludge and water to achieve dry and wet separation. The filter box 5 is connected to the sewage interface of the gate valve through a pipeline. After the food waste is processed, the hopper cavity needs to be cleaned. At this time, the gate valve is closed, the water pump is started to pump water, and the nozzles 23 spray water to clean the hopper cavity.

[0036] After cleaning, the hopper cavity needs to be dried. The hot air blower 8 and air compressor 9 are started to send hot air through heater 27 into air nozzle 28. The air nozzle 28 blows out hot air, which efficiently dries the hopper cavity. Example 3:

[0037] The working process of the hopper opening and closing mechanism 2 after installation: During operation, the first power unit 25 drives the bin cover 21 to open, and the elevator 1 lifts and tilts the garbage bin containing food, pouring the food into the hopper cavity. If a blockage occurs, the second power unit 222 of the material pushing and arch breaking device 22 drives the pusher block to reciprocate and break the blockage, allowing the food to smoothly enter the crusher 4. After processing, the gate valve is closed, the water pump is started, and the nozzle 23 rotates to spray and clean the hopper cavity. The cleaning wastewater flows into the filter box 5 for filtration through the sewage interface of the gate valve. After cleaning, the water pump is turned off, and the hot air blower 8, air compressor 9, and heater 27 are started. Hot air is blown into the hopper cavity through the air duct and air nozzle 28 for drying. After drying, one work cycle is completed.

[0038] In summary, the opening and closing of the silo cover of this utility model is smooth and reliable: two sets of symmetrically arranged first cylinders are used as the power unit to drive the opening and closing of the silo cover, ensuring that the silo cover is subjected to uniform force and avoiding jamming; at the same time, a third cylinder is set as a buffer mechanism to reduce the impact force when the silo cover is closed, protect the equipment components, and improve the safety and stability of use.

[0039] This invention prevents hopper cavity blockage: the inclined pusher and arch-breaking device is driven by a second cylinder to reciprocate within the hopper cavity, effectively breaking up bridging blockages caused by moisture, stickiness, and other factors in food, ensuring smooth feeding and improving food processing efficiency.

[0040] This invention offers convenient and thorough cleaning: the rotating multi-directional spray nozzles on the lid, combined with a flexible pipeline connecting to the water supply system, enable all-round automatic spray cleaning of the hopper cavity, eliminating the need for manual cleaning, reducing labor intensity, and ensuring a more thorough cleaning while preventing residual food from breeding bacteria.

[0041] This utility model features rapid drying and moisture prevention: the drying section at the upper edge of the hopper body blows hot air into the hopper cavity through a heater, air duct, and air nozzle, which can quickly dry the hopper cavity after cleaning, prevent moisture residue from causing equipment corrosion, extend the service life of the equipment, and keep the hopper cavity dry and clean.
