Description

Technical Field

[0001] The present invention belongs to the field of digital printing industry technology, and in particular relates to an intelligent control suction conveying platform technology for corrugated paper printing. Background Art

[0002] At present, the internal structure of the suction platform of digital printing machines is partitioned. The size of the air slot is fixed, while the size and specifications of the printing media vary. When the printing media cannot just cover the air slot, air leakage will occur, causing the suction force of the suction platform to the printing media to drop sharply. Although the adsorption force can be increased by increasing the fan power, the effect is not obvious and energy consumption is increased; by dividing the air slot into more equal parts to reduce the size of the air leakage area, it is more complicated to control, the loss between the fan and the air slot is high, and there will be small-scale air leakage, and the adsorption effect of the printing media and the belt is still unsatisfactory. In the long run, how to solve the variable size and specifications of the printing media, prevent air leakage in the printing area, and the adsorption effect of the printing media and the synchronous belt has become a major problem in the industry.

A fan joint is arranged in the wind control branch groove, and a driving motor is installed at the bottom end of the conveying platform. The driving end of the driving motor adjusts the transmission of the platform wind shield and the right alignment plate through a transmission chain. The driving end of the conveying platform is provided with a driving roller shaft, and an encoder is arranged at the bottom of the conveying platform. The encoder is externally installed with an encoder gear through a driven rotating shaft, and the driving roller shaft is externally connected with a connecting gear, and the encoder gear is meshed with the connecting gear.

[0007] As a further solution of the present invention: the feeding synchronous belt and the stainless steel bearing plate are both provided with a plurality of ventilation holes.

[0008] As a further solution of the present invention: a limiting slide rod is also installed in the wind control support groove, and an internal screw hole and a sliding through hole are respectively opened on the platform wind shield plate. The platform wind shield plate is threadedly wedged with the screw rod through the internal screw hole, and the platform wind shield plate is mounted on the limiting slide rod through the sliding through hole.

[0009] As a further solution of the present invention: the base paper blocking mechanism is laterally installed with a main support rod and an adjusting screw, the main support rod is provided with two, the adjusting screw is arranged between the main support rods, the installation side of the right side alignment plate is passed through the main support rod through a sliding sleeve, and the right side alignment plate is threadedly wedged with the adjusting screw through an inner screw hole.

[0010] As a further solution of the present invention: a transmission frame is installed at the bottom of the conveying platform, a driving wheel is installed at the driving end of the driving motor, a primary driven wheel is installed at the driving end of the adjusting screw, and a secondary driven wheel is installed at the driving end of the screw rod. A primary tensioning wheel and a secondary tensioning wheel are respectively installed on the transmission frame, and the transmission chain uses the driving wheel as the power output end, one side of the transmission chain passes through the primary driven wheel after changing direction through the primary tensioning wheel, and the other side of the transmission chain passes through the corresponding secondary driven wheel after changing direction through multiple secondary tensioning wheels, and the transmission chain as a whole is a closed structure.

[0011] As a further solution of the present invention: the fan connectors are all externally connected to an air supply mechanism, and the air supply mechanism is connected to the initial position detection sensor and the encoder in a synchronous electrical signal manner.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. Intelligent control of the size of the air duct: The air duct of the traditional suction platform is fixed. When the size of the printing medium changes, either there is no air suction at the edge or there is air leakage outside the edge. The intelligent suction conveying platform of the present invention can synchronously adjust the size of the internal air duct according to the width of the printing medium during discharge, so that the printing medium just covers the air duct.

[0014] 2. Intelligent wind control: The fan of the traditional suction platform is always on, and there is always wind in the wind slot. In the inkjet printing area, because there is always wind, when the front of the printing medium has not completely covered the wind slot and the tail has just left the wind slot, the suction will deviate the ink, resulting in double images at the front and back ends of the printing medium; while the intelligent suction conveying platform of the present invention detects the initial position through the shooting switch when the printing medium moves forward, and then calculates the position of the cardboard according to the encoder. After the printing medium covers the first wind slot, the fan of this wind slot starts to work, and when the printing medium is about to leave the wind slot, the fan of this wind slot is closed.

[0015] 3. Strong suction force and small suction force variation: Because the air duct uses the same power fan, the printing medium is completely covered on the air duct and the pressure variation is small.

[0016] 4. Energy saving: Because of air leakage in traditional air suction platforms, when the platform air suction slots are divided into multiple air suction slots, the first solution increases the number of fans, and the second solution adds control valves to the original number of fans. However, after adding pipelines and control valves, the suction wind force will decrease, and the fan power must be increased. The intelligent air suction transmission platform of the present invention has a reduced number of air slots, simple control, and is directly connected from the fan to the air slots, with less intermediate loss, the fan can use less power, and the fan works intermittently, which is more energy-saving.

[0028] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1:

[0031] A left side alignment plate 10 is installed at the left end of the base paper stop mechanism 31, a front paper stopper 11 is installed at the front end of the base paper stop mechanism 31, and a right side alignment plate 12 is also provided on the base paper stop mechanism 31. The left side alignment plate 10 and the front paper stopper 11 are both fixedly installed, and the right side alignment plate 12 is movably installed. An initial position detection sensor 6 is installed in a close-fitting manner on the side edge of the base paper stop mechanism 31.

[0032] In the present application, the conveying platform 51 is used to convey the material to be printed, the left alignment plate 10 and the front paper baffle 11 are used to limit the material to be printed, and the right alignment plate 12 is adjustable to accommodate materials of different widths. The initial position detection sensor 6 is used to detect the initial transmission position of the material and record data, so as to facilitate the subsequent tracking and calculation of the material transmission.

[0033] The inner cavity of the welding suction groove 3 is divided into a plurality of wind control branch grooves 41, and screw rods 8 are installed horizontally in the wind control branch grooves 41. Corresponding platform wind shield plates 7 are installed on the screw rods 8 through threaded connections. A fan connector 9 is arranged in the wind control branch groove 41, and the fan connector 9 is used for drainage and ventilation operations. The welding suction groove 3 is divided into a plurality of wind control branch grooves 41, and the material can be blown in an intermittent manner according to the position of the material transmission.

[0034] A driving motor 1 is installed at the bottom end of the conveying platform 51, and the driving end of the driving motor 1 adjusts the transmission of the platform windshield 7 and the right alignment plate 12 through the transmission chain 2. The driving end of the conveying platform 51 is provided with a driving roller 52 for driving the movement of the feeding timing belt 54.

[0035] In the present application, the driving roller 52 drives the feeding synchronous belt 54 to move, thereby driving the transmission of the material. While the driving roller 52 moves, it drives the encoder gear 5 to move through the gear meshing transmission. The encoder 4 can thereby record the number of transmission circles of the gear. Combined with the pulley data of the equipment, the speed and distance of the material can be calculated.

[0036] The working principle of the present invention is as follows: taking the printed corrugated paper as an example; when operating, start the machine, put the cardboard on the feeding synchronous belt 54 on the welding suction slot 3, align the left side of the cardboard with the left alignment plate 10, align the front side with the front baffle cardboard 11, start the motor 1, drive the right paper baffle alignment plate 12 to align the right side of the cardboard through the transmission chain 2, start the feeding fan, rotate the cardboard forward with the synchronous belt 3, record the paper head position after the initial position detection transmission device 6, and the encoder 4 starts to calculate the cardboard forward position. When the cardboard covers the first air slot at the printing position, the printing fan starts, the first air slot starts to ventilate, printing starts, the cardboard continues to move forward to the front air slot, and when each air slot is covered, the corresponding fan starts, and the air slot is ventilated, and so on. Since the length of the cardboard is input at the beginning, when the machine calculates that the tail of the cardboard is about to leave the first air slot, the fan of this air slot stops working, and the above sequence actions are repeated until the cardboard moves out of the platform through the synchronous belt 13, and the process ends.
