Description

Technical Field

[0001] This utility model relates to the field of sausage packaging technology, specifically a sausage quality traceability code inkjet printer. Background Technology

[0002] Chinese sausage is a meat product made from minced meat with added seasonings, stuffed into casings, and then fermented and matured. Grilled sausage is a low-temperature meat product made primarily from pork, beef, chicken, or fish, which is minced, seasoned, stuffed, and then grilled. Both Chinese and grilled sausages are packaged in bags during large-scale production. These bags are printed with quality traceability codes, which are used for quality monitoring and accountability throughout the product's lifecycle. (Existing technology: Authorization Publication No. CN 220500303) U's patent discloses a coding device for processing snack foods, including a conveyor belt and a coding head movably mounted above the conveyor belt. Guide structures are provided on both sides of the top of the conveyor belt to guide the conveyed snack foods. These guide structures move with the movement of the coding head. This coding device facilitates the guiding and conveying of the snack foods, making coding operations convenient. Furthermore, the guide structures move with the movement of the coding head to ensure coding accuracy. However, this device lacks a path detection element for sausage and grilled sausage packaging bags, resulting in a lack of effective operating instructions for the coding operation at the device's printhead, easily leading to inconsistent coding positions on the sausage and grilled sausage packaging bags. Therefore, we propose a sausage and grilled sausage quality traceability coding machine. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-3This embodiment provides a technical solution: a sausage quality traceability code inkjet printer, including a base frame 1, a housing 2 on the upper right end of the base frame 1, an upright frame 4 on the left end of the base frame 1, a lifting frame 5 slidably connected between vertical grooves on the front and rear sides of the upright frame 4, a rectangular housing 6 on the upper outer side of the lifting frame 5, a transverse housing 7 slidably connected inside the rectangular housing 6, an inkjet header 8 on the left end of the transverse housing 7, a microcontroller 3 on the inclined surface of the housing 2, the input end of the microcontroller 3 being electrically connected to an external power supply, and the output end of the microcontroller 3 being electrically connected to the input end of the inkjet header 8, and also including a second socket 13, the second socket 13 being vertically and evenly opened on the front vertical grooves. Inside, the lower front end of the lifting frame 5 is threaded with a locking bolt 14. The rear end of the locking bolt 14 is inserted into the vertically adjacent insertion hole 13. The upper side of the transverse sliding shell 7 is provided with horizontally evenly distributed insertion holes 3. The upper left end of the rectangular shell 6 is threaded with a locking bolt 15. The lower end of the locking bolt 15 is inserted into the horizontally adjacent insertion hole 3. When using the device to perform quality traceability code printing on the packaged sausages or roasted sausages, the staff first moves the device itself to the position of the belt conveyor of the external sausage or roasted sausage package (the packaged sausages or roasted sausages on the belt conveyor move longitudinally at equal intervals along the conveyor belt of the belt conveyor) according to the position of the belt conveyor of the external sausage or roasted sausage package (the packaged sausages or roasted sausages on the belt conveyor move longitudinally at equal intervals along the conveyor belt of the belt conveyor). When the conveyor approaches the area, the angle between the left side of the device and the belt conveyor is at a right angle. The operator then moves the lifting frame 5 to slide vertically along the vertical chute, thereby adjusting the vertical position of the spray dock 8 relative to the external belt conveyor. Next, the locking bolt 14 is rotated to move it longitudinally backward through its threaded connection with the lifting frame 5, so that the rear end of the locking bolt 14 engages with the vertically adjacent insertion hole 13, thus locking the vertical position adjustment of the spray dock 8. Then, the operator moves the transverse sliding shell 7 horizontally along the interior of the rectangular shell 6, thereby adjusting the transverse position of the spray dock 8 relative to the external belt conveyor. The rear locking bolt 315 is inserted into the horizontally adjacent insertion hole 3 through the same principle, thereby locking the horizontal lateral position adjustment of the spray dock 8, so that the spray dock 8 moves to a certain height above the center of the external belt conveyor bandwidth, and the middle of the sausage or roasted sausage packaged product just passes under the spray dock 8. The microcontroller 3 starts the spray dock 8 to perform quality traceability code printing operation on the middle of the upper surface of the sausage or roasted sausage packaged product. The spray dock 8 mainly includes a pressure pump, filter assembly, print head system and circuit control system. Its working principle is based on electric field deflection technology to realize non-contact printing operation of quality traceability code, and also includes a coding auxiliary mechanism 9. The coding auxiliary mechanism 9 includes a connecting seat 93, a fixed seat 94, guide rods 95, a slide 96, a laser sensor 97, and a torque adjustment assembly 98. The connecting seat 93 is installed on the lower side of the rectangular shell 6. The fixed seat 94 is located on the front wall of the connecting seat 93. The guide rods 95 are symmetrically distributed laterally between the rear wall of the connecting seat 93 and the rear side of the fixed seat 94. The slide 96 is slidably connected between the guide rods 95. The laser sensor 97 is located on the left side of both the slide 96 and the fixed seat 94. The torque adjustment assembly 98 is located between the slide 96 and the connecting seat 93. The microcontroller 3 is bidirectionally electrically connected to the laser sensor 97. The torque adjustment assembly 98 includes a stud 981, a servo motor 982, a laser sensor 983, and a bellows 984. The stud 981 is rotated via a bearing. A stud 981 is threadedly connected to a slide 96 between the rear side of the fixed base 94 and the rear wall of the connecting base 93. A servo motor 982 is located on the rear side of the connecting base 93. The input end of the servo motor 982 is electrically connected to the output end of the microcontroller 3. The output shaft of the servo motor 982 is fixedly connected to the rear end of the stud 981. A laser sensor 983 is located on the rear wall of the connecting base 93. The laser sensor 983 is bidirectionally electrically connected to the microcontroller 3. Corrugated tubes 984 are provided between the rear side of the slide 96 and the rear wall of the connecting base 93, and between the front side of the slide 96 and the rear side of the fixed base 94. The corrugated tubes 984 are movably sleeved on the outer end of the stud 981. When the sausage or roasted sausage packaged products pass under the spray nozzle 8 along the belt conveyor, the microcontroller 3 starts the front and rear... The second laser sensor 983 on the side (the laser detection part of the second laser sensor 983 on the front side and the coding part of the inkjet terminal 8 are in the same vertical plane perpendicular to the conveyor belt conveyor direction) emits a light signal to illuminate the top of the conveyor belt. When the sausage or grilled sausage packaged product passes by, the light signal emitted by the second laser sensor 983 on the front side illuminates the end of the sausage or grilled sausage packaged product and is emitted to the initial position. The second laser sensor 983 on the front side transmits the signal of the sausage or grilled sausage packaged product passing by to the microcontroller 3 in the form of an electrical signal. At this time, the microcontroller 3 obtains that the end of the sausage or grilled sausage packaged product has passed by the second laser sensor 983 on the front side. When the second laser sensor 983 on the rear side passes by in the same way... The path signal of the sausage or grilled sausage packaging product is transmitted to the microcontroller 3 via an electrical signal (the longitudinal distance between the detection points of the two laser sensors 983 is half the overall length of the sausage or grilled sausage packaging product). At this time, the middle of the sausage or grilled sausage packaging product is just below the inkjet printer 8. During the use of the sausage or grilled sausage quality traceability code inkjet printer, if the overall length of the sausage or grilled sausage packaging product changes, the staff will enter the changed overall length data of the sausage or grilled sausage packaging product into the microcontroller 3. The microcontroller 3 will subtract the initially entered overall length data of the sausage or grilled sausage packaging product from this data, and then the microcontroller 3 will take half of the difference and record it as data one. Then the microcontroller 3 will start the servo motor 982 so that its output shaft drives the stud 981 to rotate.During the rotation of stud 981, the slide 96 moves longitudinally along guide rod 95 via a threaded connection. (If this data is negative, microcontroller 3 controls servo motor 982 to rotate its output shaft in reverse, causing stud 981 to move longitudinally forward via threaded connection. If this data is positive, microcontroller 3 controls servo motor 982 to rotate its output shaft in the forward direction, causing stud 981 to move longitudinally backward via threaded connection.) Simultaneously, microcontroller 3 activates laser sensor 983, which emits a light signal that illuminates the rear of slide 96 and reflects back to its initial position. The longitudinal distance of slide 96 is detected based on the light signal propagation time and speed, and the detection result is transmitted to microcontroller 3 as an electrical signal. When microcontroller 3 receives a value that matches data, it shuts down servo motor 982. When the overall length of the sausage or grilled sausage packaging changes within the device, the detection elements adjust accordingly to ensure that the device consistently applies the quality traceability code to the center of the packaging. The exposed end of the stud 981 is sealed and lubricated by a corrugated tube 984, a corrugated structure made of multiple layers of stacked metal sheets. Its working principle is to achieve self-adaptive sealing through elastic deformation to maintain good sealing performance. This device, through the cooperation of two sets of detection elements, can detect the coding position of the sausage or grilled sausage packaging, enabling the device to apply the quality traceability code to the center of the packaging. Furthermore, the two sets of detection elements can adjust their positions according to changes in the overall length of the sausage or grilled sausage packaging, ensuring that the device consistently applies the quality traceability code to the center of the packaging. The coding auxiliary mechanism 9 also includes hollow rods 91, vertical slides 92, and locking components 99. The locking components 99 include insertion holes 991 and locking bolts 992. The hollow rods 91 are symmetrically arranged laterally on the lower side of the rectangular shell 6. Vertical slides 92 are slidably connected inside each hollow rod 91. The lower side of each vertical slide 92 is fixedly connected to the upper side of the connecting seat 93. Vertically evenly distributed insertion holes 991 are provided on the upper front side of each vertical slide 92. Locking bolts 992 are threadedly connected to the lower front side of each hollow rod 91. The rear end of the connector is inserted into the vertically adjacent insertion hole 991. The operator moves the connector 93 to make the vertical slide 92 slide vertically along the inside of the hollow rod 91, thereby adjusting the vertical position of the connector 93 so that the laser sensor 97 inside the connector 93 is at the same height as the sausage or roasted sausage packaged product conveyed on the belt of the belt conveyor. Then, the locking bolt 992 is rotated to move it backward through the same principle and insert it into the vertically adjacent insertion hole 991, thereby locking the vertical position of the connector 93 relative to the hollow rod 91 at this time. The inner wall of the outer casing 2 is equipped with an ink storage box 10. The lower end of the inner wall of the ink storage box 10 is connected to a hose 12 through a diaphragm pump 11. The input end of the diaphragm pump 11 is electrically connected to the output end of the microcontroller 3. The left end of the hose 12 is connected to the ink inlet of the inkjet printer 8. The microcontroller 3 starts the diaphragm pump 11 to transport the ink in the ink storage box 10 to the inkjet printer 8 through the hose 12. The diaphragm pump 11 is mainly composed of a transmission system, a pump head assembly, a drive mechanism, and a valve system. Its core principle is to achieve ink delivery by changing the pump chamber volume through the reciprocating motion of the diaphragm.

[0016] The working principle of the quality traceability code inkjet printer for sausages provided by this utility model is as follows: When using the device to perform quality traceability code inkjet printing on the packaged sausages, the operator first moves the device itself to a position close to the conveyor belt (the packaged sausages on the conveyor belt move at equal intervals along the conveyor belt) according to the position of the external sausage or grilled sausage packaging conveyor. At this time, the angle between the left side of the device and the conveyor belt is a right angle. Then, the operator moves the lifting frame 5 to slide vertically along the vertical chute, thereby adjusting the vertical position of the inkjet terminal 8 relative to the external conveyor belt. Then, the locking bolt 14 is rotated to connect with the lifting frame 5 by thread. The longitudinal movement causes the rear end of locking bolt 2 14 to engage with the vertically adjacent insertion hole 2 13, thereby locking the vertical position adjustment of the spray dock 8. Then, the operator moves the transverse sliding shell 7 horizontally along the interior of the rectangular shell 6, thus adjusting the transverse position of the spray dock 8 relative to the external belt conveyor. Next, locking bolt 3 15 is rotated, and its rear end engages with the horizontally adjacent insertion hole 3, thereby locking the horizontal position adjustment of the spray dock 8. This moves the spray dock 8 to a certain height above the center of the external belt conveyor width. Finally, the operator moves the connecting seat 93, causing the vertical slide 92 to slide vertically along the interior of the hollow rod 91, thus adjusting the height of the connecting seat 93. The vertical position is adjusted so that the laser sensor 97 inside the connecting seat 93 is at the same height as the sausage or roasted sausage packaged product conveyed on the belt conveyor. Then, the locking bolt 992 is rotated to move it backward through the same principle and insert it into the vertically adjacent insertion hole 991, thereby locking the vertical position of the connecting seat 93 relative to the hollow rod 91. When the sausage or roasted sausage packaged product passes below the spray mark 8 on the belt conveyor, the microcontroller 3 activates the laser sensors 983 on both the front and rear sides (the laser detection part of the front laser sensor 983 and the inkjet part of the spray mark 8 are in the same vertical plane perpendicular to the conveyor belt's feeding direction). The front laser sensor 983 emits a light signal that illuminates the area above the belt conveyor. When the sausage or grilled sausage packaged product passes through, the light signal emitted by the front laser sensor 2983 illuminates the end of the sausage or grilled sausage packaged product and is emitted to its initial position. The front laser sensor 2983 transmits the signal of the sausage or grilled sausage packaged product passing through to the microcontroller 3 in the form of an electrical signal. At this time, the microcontroller 3 obtains that the end of the sausage or grilled sausage packaged product has passed through the front laser sensor 2983. When the rear laser sensor 2983 transmits the signal of the sausage or grilled sausage packaged product passing through to the microcontroller 3 in the same way (the longitudinal distance between the detection points of the front and rear laser sensors 2983 is half the overall length of the sausage or grilled sausage packaged product), at this time, the middle of the sausage or grilled sausage packaged product is just below the spray dock 8.Subsequently, the microcontroller 3 starts the inkjet printer 8 to print a quality traceability code on the center of the upper surface of the sausage or roasted sausage packaging. The inkjet printer 8 mainly includes a pressure pump, filter assembly, printhead system, and circuit control system. Its working principle is based on electric field deflection technology to achieve non-contact printing of the quality traceability code. At the same time, the microcontroller 3 starts the diaphragm pump 11 to transport the ink in the ink storage box 10 to the inkjet printer 8 through the hose 12. The diaphragm pump 11 mainly consists of a transmission system, pump head assembly, drive mechanism, and valve system. Its core principle is to change the pump chamber volume through the reciprocating motion of the diaphragm to achieve ink delivery. During the use of the sausage quality traceability code inkjet printer, if the overall length of the sausage or grilled sausage packaging changes, the staff enters the changed overall length data into the microcontroller 3. The microcontroller 3 subtracts this data from the initial overall length data entered for the sausage or grilled sausage packaging. Then, the microcontroller 3 takes half of this difference and records it as data one. Subsequently, the microcontroller 3 starts the servo motor 982, causing its output shaft to drive the stud 981 to rotate. During the rotation of the stud 981, the slide 96 moves longitudinally along the guide rod 95 through the threaded connection. (If data one is negative, then the microcontroller 3...) The servo motor 982 is controlled to drive the stud 981 in reverse rotation via its output shaft. The stud 981, through a threaded connection, drives the slide 96 to move forward longitudinally. If this data is positive, the microcontroller 3 controls the servo motor 982 to drive the stud 981 in forward rotation via its output shaft. The stud 981, through a threaded connection, drives the slide 96 to move backward longitudinally. Simultaneously, the microcontroller 3 activates the laser sensor 983, which emits a light signal that illuminates the rear of the slide 96 and reflects back to its initial position. The longitudinal distance of the slide 96 is detected based on the propagation time and speed of the light signal, and the detection result is expressed as an electrical signal. The data is transmitted to the microcontroller 3. When the microcontroller 3 receives the detected value and finds it matches the data, it shuts down the servo motor 982. This allows the detection elements of the device to adjust accordingly when the overall length of the sausage or grilled sausage package changes, ensuring that the device always performs quality traceability code printing on the center of the sausage or grilled sausage package. The exposed end of the stud 981 is sealed and lubricated by the corrugated tube 984, a corrugated structure made of multiple layers of stacked metal sheets. Its working principle is to achieve self-adaptive sealing through elastic deformation to maintain good sealing performance.

[0017] It is worth noting that the microcontroller 3 disclosed in the above embodiments can be an STM32, the spray nozzle 8 can be an XP600 nozzle, both laser sensor 1 97 and laser sensor 2 983 can be E3C-LDA6, the servo motor 982 can be a 130SY-M10025, and the diaphragm pump 11 can be a DP micro diaphragm pump. The microcontroller 3 controls the operation of the spray nozzle 8, laser sensor 1 97, laser sensor 2 983, servo motor 982, and diaphragm pump 11 using methods commonly used in the prior art.
