Description

Technical Field

[0001] This invention relates to the field of food packaging bag printing technology, and more particularly to a food packaging bag printing device. Background Technology

[0002] Food packaging bag printing equipment is a machine that prints text or patterns onto food packaging bags using printing technology. During printing, the blow-molded packaging bags are transferred to the printing machine for filling printing, rewinding, heat sealing, heat cutting, and roll material processing. During the printing process, the temperature of the printing rollers must be maintained at around 10-15 degrees Celsius to maintain good transmittance, prevent the rubber rollers from drying out or the rubber from breaking, and also require that the rubber rollers generate little heat to maintain a constant ink density.

[0003] To address this, we propose a food packaging bag printing equipment to cool the printing rollers and prevent them from overheating during prolonged use. Summary of the Invention

[0004] The purpose of this invention is to solve the problem of excessively high printing roller temperature during long-term use in the prior art, and to propose a food packaging bag printing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A food packaging bag printing device includes two side plates, a tension roller, and a printing roller. The tension roller and the printing roller are rotatably disposed between the two side plates. The device is characterized by a rotatably disposed cleaning assembly between the two side plates. The cleaning assembly includes an inner cylinder rotatably disposed between the two side plates, and a cleaning cylinder is connected to the outside of the inner cylinder via a snap-fit ​​assembly. One end of the inner cylinder is fitted with a mounting shell that communicates with the inner cylinder. An air supply assembly is disposed inside the mounting shell to blow gas into the inner cylinder and into the cleaning cylinder. An air outlet A and an air outlet B are respectively provided through the surfaces of the cleaning cylinder and the inner cylinder.

[0007] Preferably, the snap-fit ​​assembly includes a concave block A, a concave block B, a snap-fit ​​block, and a positioning ring. The concave blocks A and B are respectively disposed at both ends of the cleaning cylinder. The snap-fit ​​block is disposed on the inner cylinder surface near the mounting shell. The positioning ring is sleeved on the inner cylinder surface to limit the position of the cleaning cylinder.

[0008] The positioning ring includes a fixing ring, and a limiting block is fixedly provided on the outer ring of the fixing ring. In use, the cleaning cylinder is put on the surface of the inner cylinder and the concave block A is put on the outside of the locking block. Then the fixing ring is put on the inner cylinder and the limiting block is locked on the concave block B. The fixing ring is detachably connected to the inner cylinder by bolts. In this way, the cleaning cylinder is restricted to the inner cylinder.

[0009] Preferably, the mounting shell includes an expanded cylindrical portion and a straight cylindrical portion connected together. The mounting shell is connected to a side plate via a support base. The support base includes a support plate connected to the side plate, and a limiting plate is provided on the support plate by bolts. A clamping groove matching the straight cylindrical portion is provided between the support plate and the limiting plate.

[0010] Preferably, the gas supply assembly is connected to the mounting housing via an installation assembly, which includes a fixing ring, a fixing rod, and a stop block. The fixing rod is connected to the outer ring of the fixing ring, and the two stop blocks are connected to the inner wall of the expansion section in pairs. In use, the fixing ring is placed in the expansion section, and the fixing rod is placed between the two stop blocks. Then, a screw passes through the expansion section from the outside and is connected to the top of the fixing rod, thereby detachably restricting the fixing ring and the fixing rod within the expansion section.

[0011] Preferably, the air supply assembly includes a motor connected in a fixed ring, and a fan blade is provided on the shaft at the output end of the motor. When the motor is connected to the power supply and started, the motor drives the fan blade to rotate through the shaft. The fan blade draws air from the rear of the motor and blows it from the expansion section to the straight section and into the inner cylinder. Then, it enters the cleaning cylinder through the air outlet B and is discharged from the air outlet A. In this way, when the food packaging bag is printed and passes under the cleaning cylinder, it is cleaned by the gas blown out of the air outlet A and the Changning air blower. At the same time, while drawing air from the rear, it can also cool the motor.

[0012] Preferably, the straight cylindrical section and the inner cylinder are connected by a transmission assembly. The transmission assembly includes a mounting rod, a gear set, and a transmission ring. The mounting rod is connected to the inner wall of the straight cylindrical section. The inner ring of the transmission ring is provided with a toothed ring. The gear set meshes with the toothed ring. When in use, the motor rotates to drive the gear set to rotate. The gear set meshes with the transmission ring to drive the transmission ring to rotate, thereby driving the inner cylinder to rotate.

[0013] Preferably, the gear set includes two gears A and one gear B. The two gears A are rotatably connected to the mounting rod via a connecting shaft, and the gear B is connected to the shaft. The two gears A mesh with each other, and gear B meshes with the lower gear A. The upper gear A meshes with the gear ring. When the motor rotates, it drives gear B to rotate via the shaft. Gear B drives the lower gear A to rotate, which in turn drives the upper gear A to rotate. The upper gear A then drives the transmission ring to rotate.

[0014] Preferably, a mounting block is provided through the middle of the gear B, and a rectangular block is fixed at one end of the mounting block. The end of the shaft is provided with a rectangular opening for accommodating the rectangular block. When the rectangular block is located in the rectangular opening, a bolt passes through the mounting block and extends into the shaft, thereby detachably connecting the mounting block and the shaft together.

[0015] Preferably, the transmission ring and the inner cylinder are connected by a connecting assembly, which includes a connecting rod and a concave block C. The connecting rod is connected to the inner wall of the transmission ring, and the concave block C is connected to the surface of the inner cylinder. When the transmission ring is fitted outside the inner cylinder, the connecting rod is placed in the concave block C and the connecting rod is connected to the concave block C by bolts. In this way, the transmission ring and the inner cylinder are detachably connected.

[0016] Preferably, the inner cylinder and the printing roller are connected at the same end by a connecting component. The connecting component includes an air-gathering cylinder, a connecting pipe, and a quick connector. The air-gathering cylinder is connected to the end of the inner cylinder, and the quick connector is connected to the end of the printing roller. The air-gathering cylinder and the quick connector are connected by a connecting pipe. In this way, when the gas is blown into the inner cylinder during use, part of it enters the cleaning cylinder, and the other part enters the printing roller through the air-gathering cylinder, the connecting pipe, and the quick connector, and then exits from the other end of the printing roller, thereby cooling the printing roller.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. The present invention facilitates air blowing to clean the surface of food packaging bags, so that dust or other particles that fall on the surface during the printing process are cleaned and blown away.

[0019] 2. In this invention, the cleaning cylinder and inner cylinder are rotated by the driving power of the air blower while the air blower is blowing air. This saves power and also allows the cleaning cylinder and inner cylinder to rotate at the same time while the packaging bag is being transported, so as to facilitate the normal pressing and transport of the packaging bag.

[0020] 3. This invention can introduce another part of the gas into the printing roller while blowing air, so as to cool the printing roller during the operation of the printing roller and provide better printing conditions for packaging bags. Attached Figure Description
