Description

Technical Field

[0001] The invention belongs to the technical field of paper bag machines, and in particular relates to a glue printing device for paper bag machines. Background Art

[0002] In the process of implementing the present invention, the inventors found that the prior art has at least the following problems:

[0003] The existing technology relies on meshing gear transmission. The distance between the glue-spreading roller and the idler roller depends on the meshing of the gears. The gear module determines the tooth height, which indirectly determines the maximum distance between the glue-spreading roller and the idler roller. The existing glue-spreading rollers are all made of large-module gears, which are clumsy in structure and large in size. They are all fixed on large wall panels and cannot move. During the gear meshing process, if the glue-spreading roller and the idler roller separate too much, the gear will be disengaged. During the operation of the equipment, if the glue-spreading work is not carried out, the gear is in an incomplete meshing state, and the gear transmission noise is very loud during the air transportation process.

[0004] In the prior art, the diameter of the conveying roller is large, resulting in a large center distance between the conveying rollers, which makes it impossible to stably feed paper when making small-sized paper bags.

[0005] CN211567120U-A cam gluing control mechanism used on a paper bag machine, discloses: a cam gluing control mechanism used on a paper bag machine, comprising a frame, a gluing mechanism installed at one end of the frame, a printing mechanism and a cutting mechanism installed at the other end of the frame, and the above technical problems cannot be solved by synchronously transmitting the gluing mechanism, the printing mechanism and the cutting mechanism. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a paper bag machine glue printing device, in which the conveying roller can move up and down, so as to be close to or away from the glue printing mechanism, so as to prevent the glue from being printed on the conveying roller when no paper bag passes through during the glue printing. During the up and down movement of the conveying roller, the gears are in a fully meshed state, the movement stroke is not affected by the gear module, and the noise caused by the collision of the gears will not occur; at the same time, the defect that the paper cannot be fed stably when making small bag surface paper bags is overcome due to the excessively large center distance of the conveying roller.

[0007] In order to solve the above technical problems, the technical solution adopted by the present invention is: a paper bag machine printing device, comprising:

[0012] It also has a swing arm, the first conveying roller is rotatably mounted on the frame; the first end of the swing arm is rotatably mounted on the frame; and the second conveying roller is rotatably mounted on the second end of the swing arm.

[0013] A power mechanism for driving the swing arm to rotate is also provided.

[0014] The power mechanism comprises a driving cylinder which is mounted on a frame and a piston rod of the driving cylinder is connected to a swing arm.

[0015] A synchronization mechanism is also provided, through which the first conveying roller and the second conveying roller are connected; the synchronization mechanism enables the first conveying roller and the second conveying roller to rotate synchronously.

[0016] The synchronization mechanism is a gear mechanism, and the first conveying roller and the second conveying roller rotate synchronously through the gear mechanism.

[0017] An intermediate mechanism is also provided, which includes an intermediate shaft, which is rotatably mounted on the swing arm, and the gears on the first conveying roller, the intermediate shaft and the second conveying roller are meshed in sequence.

[0018] The utility model also has a buffer mechanism, which includes a buffer seat, the buffer seat is installed on the frame, and a buffer block is arranged on the buffer seat, and the buffer block can be matched with the swing arm.

[0019] The rubber printing mechanism comprises a rubber printing shaft, which is rotatably mounted on a frame; and a rubber printing sponge is arranged on the rubber printing shaft.

[0020] The rubber printing shaft is located just above the second conveying roller.

[0021] One of the above technical solutions has the following advantages or beneficial effects: the conveying roller can move up and down, so as to be close to or away from the glue printing mechanism, thereby preventing glue from being printed on the conveyor when there is no glue printing on the paper bag; at the same time, during the up and down movement of the conveying roller, the gears are in a fully meshed state, the movement stroke is not affected by the gear module, and there will be no noise caused by gear collision; at the same time, it also overcomes the defect of being unable to stably feed paper due to the large center distance of the conveying roller when making small bag surface paper bags.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the 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.

[0033] See also Figures 1 to 6 , a paper bag machine printing device, comprising:

[0034] A frame 1; a conveying roller mechanism 2, which is arranged on the frame 1, and the conveying roller mechanism 2 can convey paper bags; a rubber printing mechanism 3, which is arranged on the frame 1, and the rubber printing mechanism 3 can print rubber on paper bags; the conveying roller mechanism 2 includes a first conveying roller 21 and a second conveying roller 22, and the second conveying roller 22 can adapt to the rubber printing mechanism 3 to print rubber on paper bags; the second conveying roller 22 is movably mounted on the frame 1, and the second conveying roller 22 can move relative to the rubber printing mechanism 3, and when no paper passes through the rubber printing, the second conveying roller 22 can move away from the rubber printing mechanism 3. The conveying roller can move up and down, so as to approach or move away from the rubber printing mechanism 3, so as to prevent glue from being printed on the conveying roller 22 when there is no paper bag rubber printing, and at the same time, during the up and down movement of the conveying roller, the gear 29 is in a fully meshed state, and the movement stroke is not affected by the module of the gear 29, and there will be no noise caused by the collision of the gear 29.

[0035] It also has a swing arm 26, the first conveying roller 21 is rotatably mounted on the frame 1; the first end of the swing arm 26 is rotatably mounted on the frame 1; the second conveying roller 22 is rotatably mounted on the second end of the swing arm 26. The swing of the swing arm 26 drives the first conveying roller 21 to approach or move away from the printing mechanism 3, so as to prevent the glue from being printed on the conveying roller when there is no glue on the paper bag.

[0036] A power mechanism 27 is also provided to drive the swing arm 26 to rotate. The power mechanism 27 may be a motor, a cylinder or other conventional driving mechanisms in the art.

[0037] The power mechanism 27 includes a driving cylinder 271, which is installed on the frame 1. The piston rod of the driving cylinder 271 is connected to the swing arm 26. In this embodiment, the driving cylinder 271 drives the swing arm 26 to swing. Through the swing of the swing arm 26, the first conveying roller 21 is driven to approach or move away from the printing mechanism 3 to prevent glue from being printed on the conveyor when there is no paper bag printing glue.

[0038] A synchronization mechanism is also provided, and the first conveying roller 21 and the second conveying roller 22 are connected by the synchronization mechanism; the synchronization mechanism enables the first conveying roller 21 and the second conveying roller 22 to rotate synchronously. The synchronization mechanism can ensure that the first conveying roller 21 and the second conveying roller 22 rotate in step, and the synchronization mechanism can adopt conventional mechanisms in the art such as gear mechanisms, belt mechanisms or chain mechanisms.

[0039] In this embodiment, the synchronization mechanism is a gear mechanism, and the first conveying roller 21 and the second conveying roller 22 rotate synchronously through the gear mechanism.

[0040] An intermediate mechanism is also provided, and the intermediate mechanism includes an intermediate shaft 25, which is rotatably mounted on a swing arm 26, and the gears 29 on the first conveying roller 21, the intermediate shaft 25, and the second conveying roller 22 are meshed in sequence. In order to ensure that the first conveying roller 21 and the second conveying roller 22 rotate in the same direction, the intermediate shaft 25 is provided, and the gears 29 on the first conveying roller 21, the intermediate shaft 25, and the second conveying roller 22 rotate in the same direction, so that the first conveying roller 21 and the second conveying roller 22 rotate in the same direction.

[0041] A third conveying roller 23 and a fourth conveying roller 24 are further provided on both sides of the first conveying roller 21 and the second conveying roller 22 , so that the conveying process is more stable and reliable.

[0042] The buffer mechanism 28 includes a buffer seat 281 mounted on the frame 1, and a buffer block 282 is provided on the buffer seat 281. The buffer block 282 can be adapted to the swing arm 26. During the swinging process of the swing arm 26, the swing arm 26 can be limited and can also play a buffering role.

[0043] The rubber printing mechanism 3 comprises a rubber printing shaft 31, which is rotatably mounted on the frame 1; a rubber printing sponge 32 is arranged on the rubber printing shaft 31. The rubber printing sponge 32 is provided with glue, and during the rotation of the rubber printing shaft 31, the rubber printing sponge 32 prints the glue on the paper bag.

[0044] The printing glue shaft 31 is located directly above the second conveying roller 22. The second conveying roller 22 can move relative to the printing glue mechanism 3. When no paper passes through the printing glue, the second conveying roller 22 can move away from the printing glue mechanism 3. The conveying roller can move up and down, so as to get close to or away from the printing glue mechanism 3, to prevent glue from being printed on the conveying when there is no paper bag printing glue. At the same time, during the up and down movement of the conveying roller, the gear 29 is in a fully meshed state, and the movement stroke is not affected by the modulus of the gear 29, and there will be no noise caused by the collision of the gear 29.

[0045] The printing rubber roller is fixed between the glue-spreading side plate, and the whole is located on the glue-spreading pallet. Due to the compact overall structure, the glue-spreading pallet is designed to be movable. The bottom uses a swing arm mechanism, and the bottom uses gear transition to carry out linkage design. The linkage swing arm lifts the linkage roller to move up and down. The cylinder works to lift the linkage swing arm upward to perform glue-spreading. During the up and down movement of the linkage swing arm, the gears are in a fully meshed state, and the swing stroke is not affected by the gear modulus. The main feature is that the lifting linkage roller has a small diameter and a small center distance, which can achieve a small spacing between small rollers and small bag paper bags can pass smoothly. The glue-spreading roller can be pulled out of the glue-spreading station for cleaning, which solves the problem of the trouble of cleaning the glue-spreading roller.

[0046] After adopting the above structure, the conveying roller can move up and down, so as to be close to or away from the printing mechanism, to prevent glue from being printed on the conveyor when there is no glue on the paper bag. At the same time, during the up and down movement of the conveying roller, the gears are in a fully meshed state, the movement stroke is not affected by the gear module, and there will be no noise caused by gear collision. At the same time, it also overcomes the defect of being unable to stably feed paper due to the large center distance of the conveying roller when making small bag surface paper bags.
