Description

Technical Field

[0001] The present invention belongs to the technical field of edible packaging film production, and particularly relates to a raw material cleaning device for edible packaging film production. Background Art

[0002] An edible packaging film is a food packaging material that can be safely eaten. It is usually mainly composed of natural edible substances that the human body can digest and absorb, such as proteins, starches, polysaccharides, plant fibers, edible gums, and other natural substances. Through the interaction between different molecules, a packaging film with a porous network structure is formed. Such a packaging film does not directly affect the flavor of food, and has many advantages such as light weight, hygiene, non-toxic and odorless, good quality preservation, and freshness preservation effects. Among them, starch-based edible packaging films are mainly made from potato starch and sweet potato starch. Therefore, when producing edible packaging films, raw materials such as potatoes and sweet potatoes need to be cleaned to remove impurities such as soil and sand grains to ensure the hygiene and safety of the packaging film. In the prior art, the cleaning of raw materials for edible packaging films is usually carried out by manual rinsing, which makes the labor intensity of workers relatively large, and the labor cost is relatively high. At the same time, it is also impossible to effectively remove impurities such as soil and sand grains on the raw materials of edible packaging films, resulting in poor cleaning quality. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a raw material cleaning device for edible packaging film production.

[0004] The technical solution adopted to solve the above technical problem is: a raw material cleaning device for edible packaging film production, including a main cleaning tank body. On any one side of the main cleaning tank body, a plurality of material taking ports are provided. Sealing strips are arranged in the material taking ports. Fixing reserved ports are arranged at positions of the main cleaning tank body close to the material taking ports. Threads are arranged in the fixing reserved ports. A plurality of cleaning roller shafts are installed inside the main cleaning tank body. Support legs are fixedly connected to the four corners of the bottom surface of the main cleaning tank body. A protective cover is fixedly connected to the side of the main cleaning tank body away from the material taking ports. A plurality of cleaning mechanisms are arranged inside the protective cover.

[0005] Through the above technical solution, the arrangement of the sealing strip in the material taking port can prevent the leakage of water flow during the cleaning of raw materials for edible packaging films, protect the cleanliness of the production environment. At the same time, cleaning brushes are arranged on the cleaning roller shafts, which can scrub the raw materials for edible packaging films through friction and collision.

[0006] Furthermore, a water distribution tank is fixedly connected to the top surface of the cleaning tank body. The water distribution tank is provided with a water inlet. A partition is fixedly connected to the position inside the cleaning tank body close to the water distribution tank. A plurality of support frames are fixedly connected to the top surface of the cleaning tank body. A plurality of pipe fixing members are fixedly connected to each support frame. A flushing water pipe is arranged in each pipe fixing member. A plurality of the flushing water pipes are installed on the water distribution tank. A plurality of spray heads are arranged on each flushing water pipe.

[0007] Through the above technical solution, cleaning water can be injected into the water distribution tank through the water inlet, so that the water flows into the flushing water pipes, and the raw materials of the edible packaging film below are continuously flushed through the spray heads.

[0008] Furthermore, a cleaning pipe is installed at the bottom of the water distribution tank. A cleaning water valve is arranged on the cleaning pipe. The operating rod of the cleaning water valve penetrates through the cleaning tank body close to it. A first drain port is arranged on one side of the cleaning tank body close to the cleaning water valve. A second drain port is arranged on the other side of the cleaning tank body away from the first drain port. Drain valves are installed on both the second drain port and the first drain port.

[0009] Through the above technical solution, during use, the cleaning water valve on the cleaning pipe and the drain valve on the second drain port are both in the closed state. The sewage generated by cleaning the raw materials of the edible packaging film will be discharged through the first drain port. When the cleaning is completed, the drain valve on the first drain port can be closed, and then the drain valve on the second drain port and the cleaning water valve on the cleaning pipe are opened, so that the water flows into the cleaning tank body through the cleaning pipe and the spray heads, and then is discharged through the second drain port to clean the cleaning tank body, reducing sediment residue and preventing the sediment residue from affecting the cleaning effect.

[0010] Furthermore, hinges are installed at the positions of the cleaning tank body close to the material taking port. A material taking door is installed on each hinge. A handle is fixedly connected to the side of the material taking door away from the cleaning tank body. Fixing rods are arranged at the positions of the material taking door close to the fixed reserved openings. The threaded rods of the fixing rods are arranged in the fixed reserved openings.

[0011] Through the above technical solution, by rotating the fixing rod, the threaded rod of the fixing rod can be removed from the fixed reserved opening, so that the material taking door can be opened, facilitating the staff to take out the cleaned raw materials of the edible packaging film.

[0012] Furthermore, the cleaning mechanism includes a mounting plate, a first gear is symmetrically arranged on a side of the mounting plate away from the cleaning tank body, a rotating column is fixedly connected to the side of the first gear close to the mounting plate, the rotating column passes through the mounting plate and is rotatably connected to the cleaning tank body, second gears are symmetrically arranged between the first gears, the second gears are rotatably connected to the mounting plate, the second gears are meshed with each other, and the second gears are respectively meshed with the adjacent first gears.

[0013] Through the above technical solution, when one of the first gears rotates, it will drive the meshed second gear to rotate, and make the other second gear rotate together, so that the other first gear and the rotating first gear rotate synchronously in the opposite direction.

[0014] Furthermore, a transmission column is fixedly connected to one side of the mounting plate close to the cleaning tank body, a rotating plate is fixedly connected to the outer wall of the transmission column, slots are symmetrically arranged on the rotating plate, arc grooves are symmetrically arranged on the rotating plate, sector blocks are fixedly connected to the outer wall of the rotating column, connecting rods are fixedly connected to the outer wall of the rotating column close to the sector blocks, and a blocking rod is fixedly connected to one side of the connecting rod close to the cleaning tank body.

[0015] Through the above technical solution, when the first gear rotates, it will drive the connected rotating column to rotate, so that the connecting rod will move with the rotation of the rotating column. When any baffle rod moves into a nearby slot, it will drive the rotating plate to rotate and cause the transmission column to rotate. Then, the baffle rod will disengage from the slot as the rotating column rotates, and the fan-shaped block will move into the arc groove. At the same time, the rotating plate will be limited so that it cannot rotate. When another baffle rod moves into a nearby slot, it will drive the rotating plate to reset, thereby allowing the transmission column to rotate back and forth.

[0016] Furthermore, the transmission column passes through the adjacent cleaning tank body, and a cleaning plate is fixedly connected to one end of the transmission column passing through the cleaning tank body, and a plurality of reserved holes are arranged on the cleaning plate.

[0017] Through the above technical scheme, the transmission column will drive the cleaning plate to rotate when it rotates, so that the cleaning plate continuously lifts and shakes the edible packaging film raw material, so that the edible packaging film raw material and the cleaning roller are continuously rubbed and collided, and through cooperation with the upper nozzle, the edible packaging film raw material can be fully cleaned, which effectively improves the cleaning quality of the edible packaging film raw material. At the same time, there is no need for staff to turn over the edible packaging film raw material, thereby reducing labor costs.

[0018] Further, a first transmission wheel is fixedly connected to any one of the first gears in the cleaning mechanism. The first transmission wheels are connected by a first transmission belt. A second transmission wheel is installed on the first transmission wheel located in the middle position. A motor mounting bracket is provided at the bottom of the second transmission wheel. A driving motor is installed on the motor mounting bracket. A third transmission wheel is installed on the output shaft of the driving motor. The third transmission wheel and the second transmission wheel are connected by a second transmission belt.

[0019] Further, the nozzle includes: a fixed outer tube fixedly connected to the flushing water pipe. An expansion tube is provided on the inner wall of the fixed outer tube. One end of the expansion tube is fixedly connected to the inner wall of the fixed outer tube. The other end of the expansion tube is fixedly connected to a circular ring member. A vertical sliding groove is formed on the inner wall of the fixed outer tube. The inner wall of the vertical sliding groove is slidably connected to the circular ring member. A connecting inner tube is rotatably connected to the bottom of the circular ring member. A connecting disc is fixedly connected to the bottom of the connecting inner tube. A reciprocating sliding groove is formed on the outer wall of the connecting inner tube. A positioning rod is fixedly connected to the inner wall of the fixed outer tube. The positioning rod is arranged on the inner wall of the reciprocating sliding groove. An inclined nozzle is provided at the bottom of the connecting disc. A plurality of inclined nozzles are provided. The inclined nozzles are arranged in an array.

[0020] Through the above technical solution, starting the driving motor will drive the third transmission wheel to rotate, and the second transmission wheel will be driven to rotate through the second transmission belt. When the second transmission wheel rotates, it will drive the connected first transmission wheels to rotate together. At the same time, when the first transmission wheels rotate, all the first transmission wheels will be synchronously rotated through the first transmission belt, and the first gears connected to the first transmission wheels can rotate together, enabling the cleaning mechanism to operate together and improving the cleaning efficiency of the raw materials of the edible packaging film.

[0021] The beneficial effects of the present invention are as follows: In the present invention, by providing a cleaning mechanism, when the first gear rotates, it drives the connected rotating column to rotate, causing the connecting rod to move along with the rotation of the rotating column. When any one of the blocking rods moves into the adjacent card slot, it drives the rotating plate to rotate and makes the transmission column rotate. Then, the blocking rod will disengage from the card slot as the rotating column rotates, and the sector block will move into the arc-shaped groove, simultaneously limiting the rotation of the rotating plate so that it cannot rotate. When the other blocking rod moves into the adjacent card slot, it drives the rotating plate to reset, thereby enabling the transmission column to rotate reciprocally. When the transmission column rotates, it drives the cleaning plate to rotate, causing the cleaning plate to continuously lift and shake the raw material of the edible packaging film, making the raw material of the edible packaging film continuously rub and collide with the cleaning roller shaft, and through cooperation with the upper spray head, the raw material of the edible packaging film can be fully cleaned, effectively improving the cleaning quality of the raw material of the edible packaging film. At the same time, there is no need for staff to turn over the raw material of the edible packaging film, reducing labor costs; In the present invention, by providing a divided water tank and a cleaning pipeline, during use, the cleaning water valve on the cleaning pipeline and the drainage valve on the second drainage port are both in a closed state. The sewage generated during the cleaning of the raw material of the edible packaging film will be discharged through the first drainage port. When the cleaning is completed, the drainage valve on the first drainage port can be closed, and then the drainage valve on the second drainage port and the cleaning water valve on the cleaning pipeline are opened, so that the water flows into the main body of the cleaning tank through the cleaning pipeline and the spray head, and then is discharged through the second drainage port to clean the main body of the cleaning tank, reducing sediment residue and preventing the sediment residue from affecting the cleaning effect.

[0022] In the present invention, by providing a spray head, when water flows into the spray head, the oblique nozzle rotates and moves up and down while spraying. During the rotation and up-and-down movement of the oblique nozzle, the cleaning water impacts the raw material with continuously changing trajectories and angles. This dynamic impact method, compared with spraying at a fixed position and angle, can make the impact force on the surface of the raw material more diverse and uneven. For stubborn stains attached to the surface of the raw material, this uneven impact force is more likely to shake or wash them away, thereby improving the cleaning effect. The oblique nozzle rotates and moves up and down, which can evenly disperse the impact force to all parts of the raw material, avoiding over-washing of local areas and ensuring consistent cleaning quality of the entire raw material.

[0027] The nozzle 401 includes: a fixed outer pipe 4011, the fixed outer pipe 4011 is fixedly connected to the flushing water pipe 4. An expansion pipe 4014 is arranged on the inner wall of the fixed outer pipe 4011. One end of the expansion pipe 4014 is fixedly connected to the inner wall of the fixed outer pipe 4011. The other end of the expansion pipe 4014 is fixedly connected to an annular member 4015. A vertical sliding groove 4016 is formed on the inner wall of the fixed outer pipe 4011. The inner wall of the vertical sliding groove 4016 is slidably connected to the annular member 4015, so that the annular member 4015 can slide up and down stably. When the annular member 4015 slides up and down, it drives the expansion pipe 4014 to expand and contract. The bottom of the annular member 4015 is rotatably connected to a connecting inner pipe 4012. The bottom of the connecting inner pipe 4012 is fixedly connected to a connecting disc 4013. A reciprocating sliding groove 4017 is formed on the outer wall of the connecting inner pipe 4012. A positioning rod 4018 is fixedly connected to the inner wall of the fixed outer pipe 4011. The positioning rod 4018 is arranged in the inner wall of the reciprocating sliding groove 4017. When the connecting inner pipe 4012 rotates, the reciprocating sliding groove 4017 on the connecting inner pipe 4012 rotates and interacts with the positioning rod 4018, so that the connecting inner pipe 4012 moves up and down reciprocally while rotating. The principle of the interaction between the reciprocating sliding groove 4017 and the positioning rod 4018 is the same as that of a reciprocating lead screw. An inclined nozzle 4019 is arranged at the bottom of the connecting disc 4013. A plurality of inclined nozzles 4019 are arranged, and the inclined nozzles 4019 are arranged in an array.

[0028] The working principle of this embodiment is as follows. First, put the raw materials of the edible packaging film into the main body 1 of the cleaning tank. Then, open the drain valve 105 on the first drain port 104, and inject cleaning water into the sub-tank 5 through the water inlet 501, so that the water flows into the flushing water pipe 4, and the raw materials of the edible packaging film below are continuously flushed through the spray head 401. At the same time, start the driving motor 15 to drive the third driving wheel 13 to rotate, and drive the second driving wheel 12 to rotate through the second transmission belt 14. When the second driving wheel 12 rotates, it will drive the connected first driving wheel 10 to rotate together. At the same time, when the first driving wheel 10 rotates, all the first driving wheels 10 will rotate synchronously through the first transmission belt 11, and the first gear 803 connected to the first driving wheel 10 can rotate together. When the first gear 803 rotates, it will drive the connected rotating column 802 to rotate, so that the connecting rod 809 moves with the rotation of the rotating column 802. When any one of the blocking rods 810 moves into the adjacent card slot 807, it will drive the rotating plate 806 to rotate, and make the transmission column 805 rotate. Then, the blocking rod 810 will disengage from the card slot 807 with the rotation of the rotating column 802, and the sector block 811 will move into the arc-shaped groove 808, and at the same time limit the rotating plate 806 so that it cannot rotate. When another blocking rod 810 moves into the adjacent card slot 807, it will drive the rotating plate 806 to reset, so that the transmission column 805 can rotate reciprocally. When the transmission column 805 rotates, it will drive the cleaning plate 9 to rotate, so that the cleaning plate 9 continuously lifts and shakes the raw materials of the edible packaging film, making the raw materials of the edible packaging film continuously rub and collide with the cleaning roller shaft 7, so that the raw materials of the edible packaging film can be fully cleaned. When the cleaning is completed, by rotating the fixing rod 21, the threaded rod of the fixing rod 21 can be removed from the fixing reserved port 103, so that the material taking door 19 can be opened. Then, the cleaned raw materials can be taken out through the material taking port 101. After the raw materials are taken out, close the material taking door 19 again. Then, close the drain valve 105 on the first drain port 104, and open the drain valve 105 on the second drain port 106 and the cleaning water valve 503 on the cleaning pipeline 502, so that the water flows into the main body 1 of the cleaning tank through the cleaning pipeline 502 and the spray head 401, and then is discharged through the second drain port 106 to clean the main body 1 of the cleaning tank and reduce the sediment residue, thereby improving the cleaning quality of the raw materials of the edible packaging film.

[0029] When water flow enters the nozzle 401, the water flow enters the telescopic pipe 4014, the ring part 4015, and the connecting inner pipe 4012 through the fixed outer pipe 4011, and finally sprays out through the inclined nozzles 4019 on the connecting disc 4013. At this time, when the inclined nozzles 4019 spray, they are driven by a reverse acting force to drive the connecting disc 4013 and the connecting inner pipe 4012 to rotate. When the connecting inner pipe 4012 rotates, the reciprocating chute 4017 on the connecting inner pipe 4012 rotates and interacts with the positioning rod 4018, causing the connecting inner pipe 4012 to move up and down reciprocally while rotating. The principle of the interaction between the reciprocating chute 4017 and the positioning rod 4018 is the same as that of the reciprocating lead screw, enabling the inclined nozzles 4019 to move up and down while rotating for spraying. During the rotation and up-and-down movement of the inclined nozzles 4019, the cleaning water impacts the raw materials with continuously changing trajectories and angles. This dynamic impact method, compared with spraying at a fixed position and angle, can make the impact force on the surface of the raw materials more diverse and uneven. For stubborn stains adhering to the surface of the raw materials, this uneven impact force is more likely to shake or wash them away, thereby improving the cleaning effect. If the inclined nozzles 4019 are only fixed at one position for spraying, some parts of the raw materials will be continuously and intensively rinsed, which may cause over-rinsing of these parts while insufficient cleaning of other parts. The rotation and up-and-down movement of the inclined nozzles 4019 can evenly disperse the impact force to all parts of the raw materials, avoiding local over-rinsing and ensuring consistent cleaning quality of the whole raw materials.

[0030] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
