Description

Technical Field

[0001] This utility model relates to the field of refrigerator packaging lines, and more particularly to an automatic refrigerator packaging production line. Background Technology

[0002] After the refrigerator is assembled on the production line, it will be transported to the packaging line. On the packaging line, it will pass through the centering, film covering, cartoning and sealing stations in sequence. The work of centering the refrigerator, covering the outside of the refrigerator with protective film, covering the outside of the refrigerator with carton and sealing the carton will be completed in sequence.

[0003] At the packing station, due to the presence of a film, which usually contains a lot of gas, the film bulges out on the outside of the refrigerator. Therefore, the bottom of the corrugated carton will come into contact with the bulging film during packing. If the packing process is too fast, it will damage the film. Reducing the speed to ensure the integrity of the film will reduce the packing speed. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model aims to provide an automatic refrigerator packaging production line that can, when packing corrugated cardboard boxes at the packing station, use suction to ensure the film adheres tightly to the outer wall of the refrigerator, reducing film expansion, preventing damage to the film at the bottom of the cardboard box, and improving packing efficiency.

[0005] To address the problems in the existing technology, the technical solution of this utility model is as follows:

[0006] An automatic refrigerator packaging production line includes a conveyor frame, on which a plurality of conveyor rollers are rotatably mounted in sequence along the length of the conveyor frame, and at the box-packing station, the two ends of two adjacent conveyor rollers form a passage area with the inner wall of the conveyor frame;

[0007] Two sets of suction components are symmetrically arranged at the box-making station. Each suction component has an air intake port and an exhaust port. Both the air intake port and the exhaust port are arranged vertically upwards. The two sets of suction components are located on both sides of the conveyor frame along its length, with the two air intake ports on each side located between the two exhaust ports on each side.

[0008] The two sets of suction components are driven to rise and fall by lifting components set at the box station, so that the suction port and exhaust port can rise above the conveyor frame across the passage area.

[0009] Preferably, the suction assembly includes a longitudinally arranged main pipe, and a secondary pipe is connected to the outer wall of the main pipe. The openings at the upper ends of both the secondary pipe and the main pipe are vertically upward. A one-way valve is fixed at the upper end of both the main pipe and the secondary pipe. When air enters at the lower end of the main pipe, the top opening of the secondary pipe is the exhaust port. When air exits at the lower end of the main pipe, the top opening of the main pipe is the suction port. The two main pipes on the two sets of suction assemblies are located between the two secondary pipes.

[0010] Preferably, the lifting assembly includes a longitudinally arranged linear motor, which is fixed to the outer wall of the conveyor frame, and both main pipes are installed on the moving end of the linear motor.

[0011] Preferably, airflow hoods are symmetrically fixed on the outer wall of the conveyor frame at the box station. A motor is fixed on the inner wall of the airflow hood, and an impeller is fixed on the output end of the motor. One end of the airflow hood is connected to a flexible air guide hose, and the ends of the two flexible air guide hoses opposite to the airflow hood are respectively connected to the lower ends of the two main pipes.

[0012] Preferably, air guide covers are fixed to the top of both the main pipe and the secondary pipe.

[0013] Preferably, the moving end of the linear motor is fixed with a horizontally placed carrier plate, and sleeves are symmetrically slidably fitted at both ends of the carrier plate. Bolts are threadedly connected to the outer wall of the sleeve on the side away from the main pipe through threaded holes. The ends of the bolts abut against the outer wall of the carrier plate, and the lower ends of the two main pipes are respectively fixed to the two sleeves.

[0014] Compared with the prior art, the advantages of this utility model are as follows:

[0015] 1. This utility model sets two sets of suction components on both sides of the conveyor frame along its length and at the boxing station. When the refrigerator arrives at the boxing station, air is first blown upwards from both sides of the lower part of the refrigerator through the exhaust port. Using negative pressure, the film floats away from the refrigerator, thus separating the film from the refrigerator and leaving space for the air extraction port to enter. Then the air extraction port enters the film and sucks in the air inside the film, causing the film to collapse. This greatly reduces the probability of the bottom of the carton touching the film during boxing, thereby increasing the boxing speed while ensuring that the film is not damaged.

[0016] 2. This utility model improves the adaptability of the entire packaging line by sliding two sets of main pipes on the moving end of a linear motor, which allows the spacing between the two sets of main pipes to adapt to the size of the refrigerator being transported.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figures 1 to 5 This embodiment provides an automatic refrigerator packaging production line, including a conveyor frame 1. Several conveyor rollers 2 are rotatably installed on the conveyor frame 1 along its length. A box-packing station 100 is set in the conveying area of ​​the conveyor frame 1. In the box-packing station 100, the two ends of two adjacent conveyor rollers 2 form a passage area 3 with the inner wall of the conveyor frame 1.

[0025] Along the length of the conveyor frame 1, on the outside of the conveyor frame 1, there are sequentially arranged alignment equipment for centering the refrigerator, film covering equipment for covering the refrigerator with film, carton covering equipment for covering the refrigerator with carton, and sealing equipment for sealing the carton. The alignment equipment, film covering equipment, carton covering equipment and sealing equipment are all existing technologies in the existing refrigerator packaging production line, so their structure and principle will not be described in detail.

[0026] As for how the conveyor roller 2 is driven so that the refrigerators on multiple conveyor rollers 2 can be conveyed, in the prior art, a transmission chain or transmission belt is installed between the same end of two adjacent conveyor rollers 2, so that multiple conveyor rollers 2 can rotate synchronously, thereby completing the conveying work of the conveyor roller 2. This is also the prior art, so the chain or belt structure is not shown in the figure, and its structural principle will not be described in detail.

[0027] A longitudinally arranged linear motor 134 is installed on the box-making station 100. The linear motor 134 is fixed to the outer wall of the conveyor frame 1. A horizontally placed carrier plate 5 is fixed to the moving end of the linear motor 134. Sleeves 6 are symmetrically slidably fitted on both ends of the carrier plate 5. A longitudinally arranged main pipe 7 is fixed to one side of the sleeve 6. Bolts 8 are threadedly connected to the outer wall of the sleeve 6 on the side away from the main pipe 7 through threaded holes. The ends of the bolts 8 abut against the outer wall of the carrier plate 5.

[0028] The lifting and lowering of the main pipe 7 is achieved by driving the linear motor 134 to move the carrier plate 5 up or down, thereby enabling the main pipe 7 to rise or fall. The distance between the two main pipes 7 is adjusted by rotating the bolt 8 to lock the contact sleeve 6, and then adjusting the distance between the two sleeves 6 so that the two sleeves 6 expand simultaneously or move away from each other. After adjustment, rotating the bolt 8 again will press the bolt 8 against the outer wall of the carrier plate 5, thus positioning the main pipe 7 in the adjusted position.

[0029] A secondary pipe 9 is connected to the outer wall of the main pipe 7. The openings at the upper ends of the secondary pipe 9 and the main pipe 7 are both vertically upward. A one-way valve 10 is fixed at the upper end of the main pipe 7 and the upper end of the secondary pipe 9. When air enters from the lower end of the main pipe 7, the top opening of the secondary pipe 9 is the exhaust port. When air exits from the lower end of the main pipe 7, the top opening of the main pipe 7 is the suction port. The two main pipes 7 on the two sets of suction components are located between the two secondary pipes 9. The upper ends of the two sets of main pipes 7 and secondary pipes 9 are respectively directly opposite the two passage areas 3. A guide hood 11 is fixed at the top of the main pipe 7 and the top of the secondary pipe 9. The size of the guide hood 11 is such that the guide hood 11 can just pass through the passage area 3. The height of the top surface of the main pipe 7 is higher than the height of the top surface of the secondary pipe 9.

[0030] When the refrigerator is conveyed to the cabinet station 100 via the conveyor frame 1, in this state, the two passage areas 3 are located on both sides of the bottom surface of the refrigerator. The refrigerator's positioning can be determined using a vision device or a positioning detection sensor. After positioning, the linear motor 134 operates, driving the two main pipes 7 on both sides to extend through the passage areas 3 to both sides of the refrigerator. During the ascent, gas is first introduced into the main pipe 7. At this time, the one-way valve 10 on the main pipe 7 closes, and the gas is discharged through the top of the secondary pipe 9. The exhaust port at the top of the secondary pipe 9 discharges the gas, creating a negative pressure outside the membrane. This principle is based on the fact that areas with high air velocity have low pressure, thus creating a negative pressure outside the membrane. Under the action of the film, it automatically expands to the side away from the outer wall of the refrigerator, so that the film and the outer wall of the refrigerator form a space that can accommodate the main pipe 7. Then, the two sets of main pipes 7 and the air guide shrouds 11 at the top of them extend from both sides of the refrigerator into the film. After they are in place, the gas is stopped from being introduced into the main pipes 7 and the gas inside the main pipes 7 is sucked out. At this time, the one-way valve 10 on the secondary pipe 9 is closed, and the top of the main pipe 7 is the air extraction port, so that the air inside the film is sucked out, so that the film collapses under the action of negative pressure. Then the box-fitting work is carried out. Since the film is already in close contact with the refrigerator, the box-fitting can be done quickly, and the probability of damaging the film is reduced, thus increasing the speed of box-fitting.

[0031] An airflow hood 12 is symmetrically fixed on the outer wall of the conveyor frame 1 at the housing station 100. A motor 13 is fixed on the inner wall of the airflow hood 12. An impeller 14 is fixed at the output end of the motor 13. One end of the airflow hood 12 is connected to a gas guide hose 15. The ends of the two gas guide hoses 15 away from the airflow hood 12 are respectively connected to the lower ends of the two main pipes 7. The introduction of gas into the main pipes 7 or the extraction of gas from the main pipes 7 is accomplished by driving the impeller 14 to rotate through the motor 13. When the motor 13 rotates forward, the gas in the external environment enters the airflow hood 12 and then enters the main pipes 7 through the gas guide hoses 15. When the motor 13 rotates in reverse, the air in the membrane is extracted and discharged through the main pipes 7 to the airflow hood 12.

[0032] In summary, this utility model provides two sets of suction components on both sides of the carton-packing station 100 on the conveyor frame. First, air is blown out through the exhaust port to keep the film away from the refrigerator, leaving space for suction. Then, the suction port sucks air out of the film to make it stick tightly to the refrigerator, reducing the risk of damaging the film when packing cartons and increasing the packing speed. Furthermore, by sliding the two sets of main pipes 7 on the moving end of the linear motor 134, the distance between the two sets of main pipes 7 can be adjusted to adapt to the size of the refrigerator being transported, thus improving the adaptability of the entire packaging line.
