Description

Technical Field

[0001] This utility model relates to the field of packaging box coding technology, specifically a pastry packaging box coding machine. Background Technology

[0002] For pastries packaged individually with top and bottom lids, such as mooncakes, the pastries are first placed in plastic trays, and then the sealing film is welded to the plastic trays by a sealing machine to complete the packaging. Finally, the production date is marked on the sealing film by inkjet printing.

[0003] In related technologies, manual operation is one method of inkjet printing on plastic molds. The sealing machine feeds the plastic tray onto a conveyor belt, and workers use an inkjet printer to print codes on the plastic mold. Manual printing is inefficient, produces poor results, and the printing positions are inconsistent. Another method involves installing an inkjet printer above the conveyor belt. The printer automatically prints codes as the plastic tray moves below it, relying solely on the conveyor belt for positioning. After a period of use, the printing position is prone to decentering. Furthermore, the ink does not dry quickly after printing, and if it comes into contact with the packaging box during subsequent handling, the production date may become unclear. Utility Model Content

[0004] The purpose of this invention is to provide a pastry packaging box inkjet printer to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pastry packaging box inkjet printer, including a support base, on which a feeder is provided. The feeder is used to position and transport the packaging box to prevent the packaging box from deviating and to ensure that the inkjet printing position is uniform.

[0006] A linear module is mounted on top of a support base. A coding machine is mounted on the linear module via the mounting base. The linear module controls the coding machine to sequentially print codes on the packaging box.

[0007] A photoelectric sensor is mounted on the upper surface of the support base and located on the side of the linear module. When the packaging box moves under the inkjet printer, the photoelectric sensor can detect it.

[0008] A heater is mounted above a support base and located on the other side of the linear module. An air inlet box is mounted on the upper surface of the heater, and several fans are installed inside the air inlet box.

[0009] It enables continuous automated inkjet printing on packaging boxes. Photoelectric sensors detect the position of the packaging boxes in real time and trigger the inkjet printing action to ensure accurate inkjet printing position and avoid human positioning errors. The heater and fan combination blows hot air to quickly cure the ink and prevent the date and batch number from becoming blurred due to the surface ink not drying after printing.

[0010] Furthermore, the feeder includes a placement plate and a chain connected to the placement plate. The chain is connected to a sprocket connected to a support base. Multiple placement plates are controlled by the chain to move, which can transport packaging boxes in batches. The surface of the placement plate is provided with several placement holes, and the size of the placement holes corresponds to the packaging boxes. The placement plate provides rigid support to prevent the packaging boxes from moving downwards.

[0011] Furthermore, a first support frame group and a second support frame group are installed on the upper surface of the support base. The linear module and the heater are respectively connected to the first support frame group and the second support frame group by screws to ensure stable installation of the linear module and the heater and improve the stability of the inkjet printer operation.

[0012] Furthermore, the upper surface of the air inlet box is equipped with a magnetic filter to prevent dust from entering the air inlet box, reduce the dust adhering to the fan, eliminate the need for frequent fan cleaning, and the magnetic filter can be disassembled and cleaned without tools, making maintenance convenient and quick.

[0013] Furthermore, the heater includes a heat insulation shell, inside which an electric heating rod is installed. The heat insulation shell reduces heat loss and prevents burns to operators. The air heated by the electric heating rod is blown toward the packaging box, allowing the ink to cure evenly and quickly.

[0014] Furthermore, a sealing plate is installed on the lower surface of the heat insulation shell, and the sealing plate has an air guide duct that directs hot air to the coding area to improve the ink curing speed.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) The packaging box is transported by the placement board. After the photoelectric sensor detects that the packaging box has moved to the bottom of the inkjet printer, it automatically identifies the packaging box. The linear module controls the inkjet printer to move and print the production date, batch number and other information on each packaging box in turn. It can accurately print the packaging box, ensure the uniformity of the printing position, and avoid problems such as skewed printing content, ghosting, and missing codes.

[0017] (2) The fan rotates to draw room temperature air into the air inlet box. The air passes through the heating rod, which quickly raises the air temperature to form hot air. The hot air is discharged from the air duct to dry the ink, avoiding problems such as scratches and code loss during subsequent transportation.

[0018] (3) The magnetic filter filters the dust in the air, preventing excessive dust from adhering to the fan and preventing dust from contacting the heating rod. It also prevents dust from sticking to the ink surface with the hot air and causing pitting defects. The magnetic filter is easy to disassemble and easy to clean. It can also be cleaned by wiping the magnetic filter directly. It is simple and convenient to use. Attached Figure Description

Detailed Implementation

[0024] 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.

[0025] Example:

[0026] Please see Figure 1-4 This utility model provides a technical solution: a pastry packaging box inkjet printer, including a support base 1, the support base 1 having a reinforcing rod inside to improve the structural stability of the support base 1, and a feeder provided on the support base 1, the feeder being used to position and transport the packaging box, the feeder ensuring that the packaging box moves in a straight line and will not deviate when the packaging box moves;

[0027] Linear module 8 is installed above support base 1. The linear module 8 is mounted on inkjet printer 7 via mounting base 9. The linear module 8 consists of servo motor, lead screw module, and slide rail module to ensure that mounting base 9 and inkjet printer 7 move accurately and smoothly, and can quickly print specified content on packaging boxes, such as production date, production batch number, QR code, trademark, flavor, etc.

[0028] The photoelectric sensor 5 is installed on the upper surface of the support base 1 and located on the side of the linear module 8. When the packaging box is placed on the placement plate 3, when the packaging box moves into the detection range of the photoelectric sensor 5, the photoelectric sensor 5 sends a signal to the linear module 8 and the inkjet printer 7, and the linear module 8 and the inkjet printer 7 perform inkjet printing.

[0029] The heater is installed above the support base 1 and on the other side of the linear module 8. An air inlet box 12 is installed on the upper surface of the heater. Several fans 16 are installed inside the air inlet box 12. The fans 16 accelerate the air flow. After the heater heats the air, the hot air quickly dries the ink formed by the printing on the packaging box, ensuring that the printing content is clear and complete and will not be scratched.

[0030] In this embodiment, as Figure 1 and Figure 2 As shown, the feeder includes a placement plate 3 and a chain 2 connected to the placement plate 3. The chain 2 is connected to a sprocket 18 connected to a support base 1. A support bar can be set inside the support base 1 to support the chain 2 and prevent the chain 2 from sagging. The sprocket 18 is driven by a reduction motor to achieve precise delivery of the placement plate 3. When the packaging box is placed on the placement plate 3, it is automatically delivered.

[0031] In this embodiment, as Figure 1 and Figure 2 As shown, the surface of the placement plate 3 is provided with a plurality of placement holes 4, and the size of the placement holes 4 corresponds to that of the packaging box. The packaging box is positioned when placed into the placement holes 4, which can ensure that the packaging box will not shift during transportation, prevent the packaging box from shaking, and prevent it from shifting when printing codes on the packaging box.

[0032] In this embodiment, as Figure 1 and Figure 2 As shown, a first support frame group 6 and a second support frame group 10 are installed on the upper surface of the support base 1. The linear module 8 and the heater are respectively connected to the first support frame group 6 and the second support frame group 10 by screws to ensure the safety and stability of the linear module 8 and the heater. Unscrewing the screws also makes it easy to replace the linear module 8 and the heater. The height of the second support frame group 10 is lower than that of the first support frame group 6, which is conducive to the air duct 17 being close to the packaging box, and the ink drying speed is fast.

[0033] In this embodiment, as Figure 4 As shown, the upper surface of the air inlet box 12 is provided with a magnetic filter 13. The magnetic filter 13 has a magnetic ring, the size of which corresponds to the size of the air inlet box 12. The magnetic filter 13 can be directly removed for easy cleaning.

[0034] The rotation of fan 16 generates static electricity through friction with the air. Static electricity easily attracts dust. The magnetic filter 13 can filter dust in the air, reducing dust on fan 16. The air discharged from the air inlet box 12 is also better, preventing dust from flowing onto the ink and avoiding ink spots.

[0035] In this embodiment, as Figure 3 and Figure 4As shown, the heater includes a heat insulation shell 11, and an electric heating rod 14 is installed inside the heat insulation shell 11. The heat insulation shell 11 can prevent heat loss and reduce the temperature of the heat insulation shell 11. The electric heating rod 14 adopts a finned structure, with a large heat exchange area and a fast heating speed for air.

[0036] In this embodiment, as Figure 4 As shown, a sealing plate 15 is installed on the lower surface of the heat insulation shell 11. The sealing plate 15 has air guide pipes 17. The number of air guide pipes 17 corresponds to the number and position of the packaging boxes, and the ink on the packaging boxes is dried in a targeted manner.

[0037] Specifically, during use, the plastic tray is placed into the placement hole 4 of the placement plate 3. After the spherical mooncake or other pastry is placed in the plastic tray, the chain 2 moves the plastic tray to the bottom of the sealing machine through the placement plate 3. The sealing machine connects the sealing film to the plastic tray by heat fusion, and the plastic tray and the sealing film form a packaging box.

[0038] Chain 2 transports packaging boxes via placement plate 3. When the packaging box moves into the detection range of photoelectric sensor 5, linear module 8 starts to control inkjet printer 7 to move above the packaging box. Inkjet printer 7 prints the production date, production batch number, trademark and other information on the sealing film of the packaging box with ink. After completing the inkjet printing of six packaging boxes, linear module 8 controls inkjet printer 7 to reset.

[0039] Next, chain 2 transports the packaging boxes to the bottom of air duct 17 via placement plate 3. Fan 16 accelerates the air into air inlet box 12. The air flows from air inlet box 12 through heating rod 14 and is heated into hot air. The hot air is discharged from air duct 17 to dry the ink on the six packaging boxes, ensuring that the printed content is clear and complete.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
