The inkjet printer 19 is a prior art and its specific structure will not be described in detail here.

[0031] Furthermore, the transmission unit includes a lifting screw 20, the lower part of which is a non-threaded area. The non-threaded area of ​​the lifting screw 20 is rotatably installed in the third-level rotating mouth, and the lifting block 17 is screwed to the threaded area of ​​the lifting screw 20.

[0032] With the above structure, the surface of the lifting screw 20 is composed of a threaded area and a non-threaded area. The non-threaded area is rotatably installed in the three-level rotation port, and the threaded area is screwed to the lifting block 17 to provide power for the lifting of the lifting block 17.

[0033] Furthermore, the transmission unit also includes a primary bevel gear 21, which is fixedly mounted at the bottom end of the lifting screw 20. A fourth-stage rotating opening is opened in the primary mounting groove, and a driving rod 22 is rotatably mounted in the fourth-stage rotating opening. One end of the driving rod 22 is fixedly connected to one end of the worm 8, and a secondary bevel gear 23 is fixedly mounted on the other end of the driving rod 22. The primary bevel gear 21 is meshed with the secondary bevel gear 23.

[0034] By means of the above structure, the worm 8 drives the driving rod 22 to rotate, the driving rod 22 drives the secondary bevel gear 23 to rotate, and the secondary bevel gear 23 drives the lifting screw 20 to rotate through the primary bevel gear 21 .

[0035] Furthermore, the cleaning assembly includes a moving rod 31, which is vertically arranged. A transversely arranged cross bar 32 is installed on the top of the moving rod 31, a scraper 33 is fixedly installed on the lower side of the cross bar 32, a scraping unit is slidably installed on the inner wall of the cross bar 32, and a drying unit is fixedly installed on the lower side of the cross bar 32.

[0036] By means of the above structure, the distance between the scraper 33 installed on the lower side of the cross bar 32 and the placement plate 2 is just consistent with the height of the placed meat packaging box. Its purpose is to scrape off the grease stained on the cling film on the upper side of the meat packaging box to prevent grease interference, which will lead to reduced adhesion effect of the coding ink.

[0037] Furthermore, the scraping unit includes a moving block 34, which is slidably mounted in the cross bar 32, and a connecting port is opened on the lower side of the cross bar 32. A cleaning scraper 35 is fixedly mounted on the lower side of the moving block 34. A driving reciprocating screw rod 36 is rotatably mounted in the cross bar 32. In this embodiment, one end of the driving reciprocating screw rod 36 close to the moving rod 31 is rotatably connected to the moving rod 31, and the moving block 34 is screwed on the driving reciprocating screw rod 36. A U-shaped frame 41 is fixedly mounted on the upper side of the base 1, and a driving tooth plate 42 is fixedly mounted on the upper side of the U-shaped frame 41. A driving gear 37 is rotatably mounted on one end of the driving reciprocating screw rod 36, and the driving gear 37 is meshed with the driving tooth plate 42. A ratchet 38 is rotatably mounted on the surface of the driving reciprocating screw rod 36, and a reset spring 39 is fixedly mounted on the surface of the ratchet 38. The other end of the reset spring 39 is fixedly mounted on the driving reciprocating screw rod 36, and a ratchet 40 is provided on the inner wall of the driving gear 37. In this embodiment, the connection port restricts the moving block 34 to prevent it from rotating along with the driving reciprocating screw rod 36 .

[0038] By means of the above structure, the interior of the crossbar 32 is hollow, and the connection port opened at the lower side runs through the entire crossbar 32. The moving block 34 is connected to the cleaning scraper 35 through the connection port. When the scraper 33 cleans the packaging box, the driving reciprocating screw rod 36 drives the driving gear 37 to rotate under the action of the driving tooth plate 42. At this time, the ratchet 38 disengages from the ratchet 40 and does not produce a clamping effect with it. When the scraper 33 is reset, the driving gear 37 rotates in the opposite direction. The ratchet 38 produces a clamping effect with the ratchet 40 through the reset spring 39, so that the driving reciprocating screw rod 36 and the driving gear 37 are clamped, thereby driving the driving reciprocating screw rod 36 to rotate and provide power for the moving block 34. When the scraper 33 is completely reset, the cleaning scraper 35 reaches the other side of the scraper 33. When it is reused again, the driving reciprocating screw rod 36 can be used to make the moving block 34 move in the opposite direction. That is, the driving reciprocating screw rod 36 and the driving gear 37 are one-way transmission.

[0039] Further, the drying unit includes an air duct 43, which is fixedly mounted on the lower side of the cross bar 32, and has a plurality of nozzles on the lower side of the air duct 43, each of which has a nozzle 44 fixedly mounted therein, an air inlet 45 on one end of the air duct 43, a avoidance port 49 on one side of the U-shaped frame 41, a bellows 47 fixedly mounted on the inner wall of the U-shaped frame 41, an air inlet pipe 46 fixedly mounted in the air inlet 45, wherein the air inlet pipe 46 is a hard pipe, a gas delivery port is disposed on one side of the bellows 47, the other end of the air inlet pipe 46 is fixedly connected to and communicated with the bellows 47, a one-way valve is mounted on the air inlet pipe 46, an air inlet 48 is disposed on one side of the bellows 47, and a one-way valve is fixedly mounted in the air inlet 48. In this embodiment, both ends of the bellows 47 are closed by hard plates, and the bellows 47 can be replaced by an air bag.

[0040] By means of the above structure, the nozzle 44 is arranged higher than the scraper 33 to prevent the nozzle 44 from directly sticking to the surface of the fresh-keeping sealing film. The nozzles 44 are installed on the lower side of the air duct 43 at equal intervals. The air inlet pipe 43 is made of hard material. The one-way valve installed on the air inlet pipe 46 allows compressed gas to enter the air inlet pipe 43 through the bellows 47. Since the air inlet pipe 46 is a hard pipe, it can move synchronously with the cross bar 32 and thus drive the bellows 47 to be compressed and expanded. The bellows 47 is a prior art and will not be described in detail here. The one-way valve on the air inlet 48 of the bellows 47 allows gas to enter the bellows 47. When the air inlet pipe 43 moves to the maximum position, the bellows 47 extends to the maximum deformation state.

A transmission wheel 29 is rotatably installed in the U-shaped mounting groove, and a transmission belt 30 is arranged between the driving wheel 28 and the transmission wheel 29. The lower end of the moving rod 31 can slidably extend into the U-shaped mounting groove and is fixedly connected to the transmission belt 30.

[0042] By means of the above structure, the mounting opening is connected with the sliding opening. When the driving gear rod 25 moves downward, it drives the primary gear 27 to rotate, the primary gear 27 drives the transmission rod 26 to rotate, the transmission rod 26 drives the driving wheel 28 to rotate, the driving wheel 28 drives the transmission belt 30 to move under the action of the transmission wheel 29, the transmission belt 30 drives the moving rod 31 to move, and provides power for the moving rod 31.

Since the size of the packaging box is fixed, when the lower pressing plate 11 is pressed tightly against the sealing position of the packaging box, the positioning plate 3 also makes the packaging box just located in the coding area at the center point of the placement plate 2.

[0044] In the process of positioning the packaging box, the worm 8 drives the driving rod 22 to rotate, the driving rod 22 drives the secondary bevel gear 23 to rotate, the secondary bevel gear 23 drives the primary bevel gear 21 to rotate, the primary bevel gear 21 drives the lifting screw 20 to rotate, the lifting screw 20 drives the lifting block 17 to move downward along the lifting slot, the lifting block 17 drives the mounting frame 18 to move downward, the mounting frame 18 drives the inkjet printer 19 to move downward, so that the inkjet printer 19 gradually approaches the inkjet printing area, and at the same time the mounting frame 18 drives the connecting block 24 to move downward, and the connecting block 24 drives the driving gear rod 25 to move downward. The driving gear rod 25 drives the first-stage gear 27 to rotate, the first-stage gear 27 drives the transmission rod 26 to rotate, the transmission rod 26 drives the driving wheel 28 to rotate, the driving wheel 28 drives the transmission belt 30 to move under the action of the transmission wheel 29, the transmission belt 30 drives the moving rod 31 to move, so that the moving rod 31 is close to the meat packaging box, the moving rod 31 drives the cross bar 32 to move, and the cross bar 32 drives the scraper 33 to move, so that the scraper 33 contacts and fits the fresh-keeping film on the upper side of the meat packaging box to move, scrape off the grease on the surface of the fresh-keeping film during packaging, and prevent the fuzzy inkjet code caused by the grease.

[0045] At the same time, the cross bar 32 drives the air duct 43 to move, and the air duct 43 drives the air inlet pipe 46 to move. The air inlet pipe 46 passes through the avoidance port 49 to drive the bellows 47 to stretch, and under the action of the one-way valve of the air inlet pipe 46, the bellows 47 inhales gas through the air intake port 48 during the stretching process. When the scraper 33 is cleaned, the inkjet printer 19 reaches the predetermined coding area, and the controller 50 stops driving the motor 9 and starts the inkjet printer 19 to perform traceability code coding on the fresh-keeping sealing film on the upper side of the packaging box that has been cleaned. During the coding process, the controller 50 starts the heat sealing film 12 for a short period of hot melting, and performs secondary hot melt sealing on the sealing portion to prevent the situation where the sealing is not firm and the fresh-keeping sealing film curls and affects the coding.

[0046] After the coding is completed, the controller 50 starts the driving motor 9 to reverse. At this time, the inkjet printer 19 resets upward, the four positioning plates 3 begin to move away from the meat packaging box, and the cross bar 32 resets. When the cross bar 32 is reset, it drives the driving reciprocating screw rod 36 to move, and the driving reciprocating screw rod 36 drives the driving gear 37 to translate. The driving gear 37 rotates under the action of the driving tooth plate 42. At this time, the ratchet fixed on the surface of the driving reciprocating screw rod 36 is clamped in the ratchet 40 of the driving gear 37 under the action of the reset spring 39, so that the driving gear 37 drives the driving reciprocating screw rod 36 to rotate, and the driving reciprocating screw rod 36 drives the moving block 34 to move, and the moving block 34 drives the cleaning scraper 35 moves, the cleaning scraper 35 is attached to the surface of the scraper 33, the grease scraped off the surface of the scraper 33 is cleaned, and the reuse effect of the scraper 33 is enhanced. At the same time, the air inlet pipe 46 drives the bellows 47 to be compressed, and under the action of the one-way valve in the air intake port 48, the gas in the bellows 47 is transported to the air duct 43 through the air inlet pipe 46, and is sprayed out through the nozzle 44 on the lower side of the air duct 43 to dry the ink of the traceability code to prevent the traceability code from being blurred due to accidental smearing of the ink that is not completely dried. When the cross bar 32 is reset to the starting position, the controller 50 stops the device, removes the meat packaging that has been coded, and completes the coding of the livestock meat traceability code.
