Description

Technical Field:

[0001] The present invention relates to the field of packaging bag printing equipment, and particularly relates to a cleaning device for the surface of packaging bags on a packaging bag printing line. Background Art:

[0002] Printing machinery is a general term for printing presses, binding machines, plate-making machines and other mechanical equipment and other auxiliary mechanical equipment. These mechanical equipment have different performances and uses. Therefore, the mechanical forms that make them up are not completely the same. When a printing press is working, the text and images to be printed are first made into printing plates and installed on the printing press. Then, ink is applied to the places with text and images on the printing plate manually or by the printing press, and then directly or indirectly transferred to paper or other printing substrates, so as to reproduce the same printed matter as the printing plate.

[0003] When a traditional printing press prints a packaging bag, a large amount of static electricity will be generated due to the repeated friction between the packaging bag and the machine tool. Dust is adsorbed on the surface of the packaging bag under the action of static electricity, resulting in unclear printing patterns; the existing packaging bag printing machines lack corresponding dust removal devices during use. Manual dust removal not only wastes manpower, but also reduces production efficiency, seriously affecting the printing effect. Summary of the Invention:

[0004] Aiming at the problems in the prior art, the purpose of the present invention is to provide a cleaning device for the surface of packaging bags on a packaging bag printing line.

[0005] A cleaning device for the surface of packaging bags on a packaging bag printing line, comprising a workbench. Both the front and rear sides of the workbench are fixedly installed with baffles. There are two conveyor belts between the two groups of baffles. Two guiding rollers are rotatably installed between the baffles. The two guiding rollers are located at the right end of the workbench. A dust removal roller is rotatably installed between the baffles. A brush is fixedly installed on the outer side of the dust removal roller. The dust removal roller penetrates through the front baffle. The dust removal roller is located between the two guiding rollers. A dust removal table is fixedly installed on the rear side wall at the right end of the workbench. An electrostatic removal table is fixedly installed on the front side wall at the right end of the workbench;

[0006] In the middle of the upper side of the electrostatic removal table, a motor is fixedly installed. The output shaft of the motor is fixedly connected to the dust removal roller. A semi-gear is fixedly installed on the output shaft of the motor. The electrostatic removal table is provided with a second chute along the length direction of the workbench. A spring is fixedly installed at the right end of the second chute. The left end of the spring is fixedly connected to a second toothed plate. The second toothed plate is slidably connected to the second chute. The second toothed plate is meshed with the semi-gear. A diversion box is fixedly installed at the left end of the second toothed plate;

[0007] A first blower is fixedly installed on the front side of the upper surface of the static elimination table. The first blower is connected to an ion generator through a pipeline. The ion generator is fixedly installed above the static elimination table. The ion generator is movably connected to the diversion box through a corrugated hose.

[0008] It further includes a printing device which is fixedly installed at the left end of the upper surface of the workbench.

[0009] It further includes a dust removal device which is fixedly installed above the dust removal table.

[0010] Preferably, the printing device includes a cantilever which is fixedly installed above two groups of baffles. A through hole is provided in the middle of the cantilever. An electric push rod is fixedly installed in the through hole. The telescopic end of the electric push rod is fixedly installed with a printing plate.

[0011] Preferably, a first toothed plate is fixedly installed at one end of the printing plate. A rotating shaft is rotatably installed in the inner cavity of the cantilever. A gear is fixedly installed in the middle of the rotating shaft. The gear is meshed with the first toothed plate. Pressing rods are fixedly installed at both ends of the rotating shaft. Pressing wheels are rotatably installed at the bottom ends of the pressing rods. The two groups of pressing wheels are vertically aligned with the two groups of conveyor belts.

[0012] Preferably, a first sliding groove is provided in the middle of the cantilever. The first toothed plate is slidably connected to the first sliding groove. A number of groups of pulleys are provided on both sides of the first toothed plate. The pulleys are in direct rolling contact with the first sliding groove.

[0013] Preferably, six groups of pulleys are provided.

[0014] Preferably, the dust removal device includes a collection box which is fixedly installed on the upper surface of the dust removal table. The right end of the collection box is connected to a second blower through a pipeline. The left end of the collection box is connected to a flared opening through a pipeline. The flared opening is fixedly installed in the middle of the baffle and penetrates through the baffle.

[0015] Preferably, a number of groups of filter sheets are provided inside the collection box.

[0016] Preferably, a number of groups of diversion pipes are provided inside the diversion box. A clamping groove is provided at the right end of the diversion box. The clamping groove is movably clamped with the front baffle.

[0017] Preferably, the length of the clamping groove is equal to the height of the baffle, and the length of the diversion box is greater than the width of the workbench.

[0018] The beneficial effects of the present invention are:

[0019] By driving the dust removal roller rotatably installed between the baffles by a motor, the dust on the surface of the packaging bag is preliminarily cleaned, so that most of the dust is separated from the packaging bag, and the turned-up dust is sucked into the collection box by the second blower for collection and treatment.

[0020] The output shaft of the motor drives the semi-gear to rotate, which in turn meshes with and drives the second toothed plate to move horizontally in the second chute, thereby driving the diversion box to move on the surface of the workbench. The ion generator emits ions onto the packaging belt through the diversion box, solving the problem of electrostatic dust adsorption of traditional printing devices and achieving the effect of eliminating static electricity on the surface of the packaging bag.

[0021] The electric push rod drives the printing plate to press down for printing the packaging bag, and then drives the toothed plate to move downward in the first chute. The meshing-connected gear rotates to drive the rotating shaft to rotate, so that the pressing rod drives the pressing wheel to move upward. When the printing plate moves upward, the pressing wheel moves downward, ensuring the stable transportation of the packaging bag on the workbench. At the same time, the electric push rod stretches and retracts regularly, facilitating the counting of the printed packaging bags. Description of the Drawings:

[0030] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below with reference to specific drawings.

[0031] Example 1: As Figure 1-2 shown, a cleaning device for the surface of packaging bags on a packaging bag printing line includes a workbench 1. Baffles 2 are fixedly installed on both the front and rear sides of the workbench 1. Two conveyor belts 3 are provided between the two baffles 2.

A dust removal roller 12 is rotatably installed between the baffles 2. A brush 121 is fixedly installed on the outer side of the dust removal roller 12. The rotation of the dust removal roller drives the brush to clean the packaging bags on the workbench, and preliminarily lift the dust on the surface of the packaging bags. The dust removal roller 12 penetrates the front baffle 2. The dust removal roller 12 is located between the two guide rollers 11. A dust removal table 23 is fixedly installed on the rear side wall of the right end of the workbench 1. A static elimination table 13 is fixedly installed on the front side wall of the right end of the workbench 1.

[0032] A motor 14 is fixedly installed in the middle on the upper side of the static elimination table 13. The output shaft of the motor 14 is fixedly connected to the dust removal roller 12.

A spring 18 is fixedly installed at the right end of the second chute 17. The left end of the spring 18 is fixedly connected to a second toothed plate 16. The second toothed plate 16 is slidably connected to the second chute 17. The second toothed plate 16 is meshed with the half gear 15. The motor drives the meshing transmission between the half gear and the second toothed plate. When the teeth of the half gear contact the toothed plate, the second toothed plate is driven to move in the chute. When the toothless area of the half gear contacts the toothed plate, the second toothed plate returns to its original position under the action of the spring. A flow guide box 19 is fixedly installed at the left end of the second toothed plate 16. The flow guide box moves synchronously with the second toothed plate. When the motor works, the flow guide box reciprocates on the surface of the workbench.

[0033] A first blower 22 is fixedly installed on the front side of the upper surface of the static elimination table 13. The first blower 22 is connected to an ion generator 20 through a pipeline. The ion generator 20 is fixedly installed above the static elimination table 13. A large number of ions generated by the ion generator are transported to the diversion box by the first blower. The ion generator 20 is movably connected to the diversion box 19 through a corrugated hose 21. The diversion box reciprocates on the surface of the workbench, so that ions are evenly dispersed on the surface of the packaging bag. The charged particles on the surface of the packaging bag are neutralized by the ions, thereby eliminating static electricity and weakening the adsorption ability of dust on the surface of the packaging bag.

[0034] It further includes a printing device. The printing device is fixedly installed at the left end of the upper surface of the workbench 1. The printing device includes a cantilever beam 4. The cantilever beam 4 is fixedly installed above two groups of baffles 2. A through hole 42 is provided in the middle of the cantilever beam 4. An electric push rod 5 is fixedly installed in the through hole 42. The telescopic end of the electric push rod 5 is fixedly installed with a printing plate 10. The printing plate is driven by the electric push rod to move up and down, so as to print the packaging bag, which can improve the automation level of the printing equipment and facilitate counting the printed packaging bags at the same time.

[0035] It further includes a dust removal device. The dust removal device is fixedly installed above the dust removal table 23. The static electricity generated between the packaging bag and the workbench is eliminated by the static elimination device, the dust adsorption ability is reduced, and then the dust on the surface of the packaging bag is collected and processed by the dust removal device.

[0036] The dust removal device includes a collection box 25. The collection box 25 is fixedly installed on the upper surface of the dust removal table 23. The right end of the collection box 25 is connected to a second blower 26 through a pipeline. The left end of the collection box 25 is connected to a bell mouth 24 through a pipeline. The bell mouth 24 is fixedly installed in the middle of the baffle 2 and penetrates the baffle 2. The dust on the packaging bag is collected by the suction ability of the blower, and the dust is stored in the collection box.

[0037] A number of filter sheets 251 are provided inside the collection box 25 to prevent dust from flying out through the blower and polluting the working environment.

[0038] A number of diversion pipes 191 are provided inside the diversion box 19. A clamping groove 192 is provided at the right end of the diversion box 19. The clamping groove 192 is movably clamped with the front baffle 2. The diversion box reciprocates on the baffle through the second toothed plate, and ions are evenly transported to the surface of the packaging bag.

[0039] The length of the clamping groove 192 is equal to the height of the baffle 2, and the length of the diversion box 19 is greater than the width of the workbench 1.

[0040] Example 2: As Figure 1-6As shown in the figure, a cleaning device for the surface of packaging bags on a packaging bag printing line includes a workbench 1. On both the front and rear sides of the workbench 1, baffles 2 are fixedly installed. Between the two groups of baffles 2, two conveyor belts 3 are provided. Between the baffles 2, two guiding rollers 11 are rotatably installed. The two guiding rollers 11 are located at the right end of the workbench 1. Between the baffles 2, a dust removal roller 12 is rotatably installed. On the outer side of the dust removal roller 12, a brush 121 is fixedly installed. The rotation of the dust removal roller drives the brush to clean the packaging bag on the workbench, initially turning up the dust on the surface of the packaging bag. The dust removal roller 12 penetrates through the front baffle 2 and is located between the two guiding rollers 11. On the rear side wall at the right end of the workbench 1, a dust removal table 23 is fixedly installed. On the front side wall at the right end of the workbench 1, an electrostatic eliminator table 13 is fixedly installed.

[0041] In the middle of the upper side of the electrostatic eliminator table 13, a motor 14 is fixedly installed. The output shaft of the motor 14 is fixedly connected to the dust removal roller 12. By driving the dust removal roller with the motor, the cleaning strength of the dust on the surface of the packaging bag is enhanced. On the output shaft of the motor 14, a semi-gear 15 is fixedly installed. Along the length direction of the workbench 1, a second chute 17 is provided on the electrostatic eliminator table 13. At the right end of the second chute 17, a spring 18 is fixedly installed. The left end of the spring 18 is fixedly connected to a second toothed plate 16. The second toothed plate 16 is slidably connected to the second chute 17. The second toothed plate 16 is meshed with the semi-gear 15. The motor drives the meshing transmission between the semi-gear and the second toothed plate. When the teeth of the semi-gear contact the toothed plate, it drives the second toothed plate to move in the chute. When the toothless area of the semi-gear contacts the toothed plate, the second toothed plate returns to its original position under the action of the spring. At the left end of the second toothed plate 16, a diversion box 19 is fixedly installed. The diversion box moves synchronously with the second toothed plate. When the motor works, the diversion box makes a reciprocating motion on the surface of the workbench.

[0042] On the front side of the upper surface of the electrostatic eliminator table 13, a first blower 22 is fixedly installed. The first blower 22 is connected to an ion generator 20 through a pipeline. The ion generator 20 is fixedly installed on the upper side of the electrostatic eliminator table 13. Through the first blower, a large number of ions generated by the ion generator are transported into the diversion box. The ion generator 20 is movably connected to the diversion box 19 through a corrugated hose 21. The diversion box makes a reciprocating motion on the surface of the workbench, so that the ions are evenly dispersed on the surface of the packaging bag. By ionizing and neutralizing the charged particles on the surface of the packaging bag, the static electricity is eliminated, and the adsorption ability of the dust on the surface of the packaging bag is weakened.

[0043] It also includes a printing device which is fixedly installed at the left end of the upper surface of the workbench 1. The printing device includes a cantilever beam 4 which is fixedly installed above two groups of baffles 2. A through hole 42 is provided in the middle of the cantilever beam 4, and an electric push rod 5 is fixedly installed in the through hole 42. The telescopic end of the electric push rod 5 is fixedly installed with a printing plate 10. By driving the printing plate to move up and down through the electric push rod, the packaging bag can be printed, which can improve the automation level of the printing equipment and facilitate the counting of the printed packaging bags.

[0044] One end of the printing plate 10 is fixedly installed with a first toothed plate 6. A rotating shaft 7 is rotatably installed in the inner cavity of the cantilever beam 4. A gear 8 is fixedly installed in the middle of the rotating shaft 7. The gear 8 is meshed with the first toothed plate 6. By driving the first toothed plate to move up and down through the up and down movement of the printing plate, the gear meshed with the first toothed plate rotates. When the electric push rod extends, the gear rotates clockwise in the front view direction. When the electric push rod contracts, the gear rotates counterclockwise in the front view direction. Pressing rods 9 are fixedly installed at both ends of the rotating shaft 7. Pressing wheels 91 are rotatably installed at the bottom ends of the pressing rods 9. The rotation of the gear drives the rotation of the rotating shaft, thereby driving the rotation of the pressing rods. The two groups of pressing wheels 91 are vertically aligned with the two groups of conveyor belts 3. When the electric push rod extends, the pressing rod lifts up and the pressing wheel moves away from the packaging bag, and the packaging bag is printed by the printing plate. When the electric push rod contracts, the pressing rod presses down and the pressing wheel presses the packaging bag tightly, and drives the packaging bag to move leftward under the action of the conveyor belt, avoiding the packaging bag from slipping on the conveyor belt.

A number of groups of pulleys 61 are provided on both sides of the first toothed plate 6. The pulleys 61 are in direct rolling contact with the first sliding groove 41. The cooperation between the first sliding groove and the first toothed plate improves the stability of the movement. The design of the pulley effectively reduces the friction force, saves energy and improves the work efficiency.

[0046] Six groups of the pulleys 61 are provided.

[0047] It also includes a dust removal device which is fixedly installed above the dust removal table 23. The static electricity generated between the packaging bag and the workbench is eliminated by the static electricity removal device, reducing the dust adsorption ability, and then the dust on the surface of the packaging bag is collected and processed by the dust removal device.
