Description

Technical Field

[0001] The utility model relates to the technical field of punching machines, in particular to a rubber roller replacement mechanism for a punching machine. Background Technique

[0002] After the packaging bag is produced and sealed, there will be air in the packaging bag. Because there is air in the packaging bag, it will not only occupy too much space during transportation, but also the internal air pressure of the packaging bag may cause the packaging bag to burst during transportation. In order to discharge the excess gas in the packaging bag, most of the packaging bags need to be punched by a punching device after being sealed, so as to discharge the air in the packaging bag.

[0003] In the prior art, when punching the packaging bag, the packaging bag raw material is mostly placed on the brush roller, and the brush roller drives the packaging bag to rotate. When the packaging bag encounters the needle roller below the brush roller, the needle roller will punch holes in the packaging bag. Because the brush is relatively soft, when the brush roller drives the packaging bag to rotate, the needle roller sometimes cannot penetrate the packaging bag, so that the punching and exhaust effect of the packaging bag is not good, and even the packaging bag cannot be punched and exhausted, thus unable to meet the production requirements.

[0004] In view of the above technical problems, this application proposes a solution. Content of the Utility Model

[0022] The technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0023] Please refer to Figures 1 - 5As shown in the figure, a rubber roller replacement mechanism for a punching machine includes a base 1; one side of the outer wall of the base 1 is fixedly connected with a motor 2 through a fixing plate, and the base 1 is in a U shape; the output end of the motor 2 is provided with a rotating shaft 3, and one end of the outer wall of the rotating shaft 3 penetrates through one side of the outer wall of the base 1 and is rotatably connected to one side of the inner wall of the base 1; one side of the inner wall of the base 1 is rotatably connected with a needle roller 4, and one end of the outer wall of the needle roller 4 penetrates through the base 1, and the needle roller 4 is located below the rotating shaft 3; both the outer side wall of the end of the rotating shaft 3 that does not penetrate the base 1 and the outer side wall of the end of the needle roller 4 that penetrates the base 1 are fixedly connected with a first gear 5, and a pair of first gears 5 are meshed with each other; a set of rubber roller bodies 6 are sleeved on the outer side wall of the end of the rotating shaft 3 that penetrates through one side of the outer wall of the base 1, and the rubber roller bodies 6 are matched with the needle roller 4. By replacing the brush 19 with the rubber roller bodies 6, when the packaging bag is placed on the rubber roller bodies 6 for rolling punching, because the material of the rubber roller bodies 6 is harder, it is more convenient for the needle roller 4 to punch holes, and it is not easy for the needles on the needle roller 4 to not penetrate the packaging bag, so that it is more convenient for the packaging bag to perform the punching process, and the punching effect and quality are better.

[0024] The rubber roller body 6 includes a first half roller 601 and a second half roller 602; a pair of clamping blocks 7 are fixedly connected to one side of the outer wall of the first half roller 601; a pair of clamping grooves 8 are opened on one side of the outer wall of the second half roller 602, and a pair of clamping grooves 8 are respectively matched with a pair of clamping grooves 8; a pair of threaded grooves 9 are opened on one side of the outer wall of the second half roller 602; a pair of square grooves 10 are opened at one end of the outer wall of the first half roller 601; one end of the outer wall of each of the pair of square grooves 10 is threadedly connected with a bolt 11, and one end of the outer wall of each of the pair of bolts 11 penetrates through the first half roller 601, and the pair of bolts 11 are respectively matched with the pair of threaded grooves 9. Since the rubber roller body 6 includes the first half roller 601 and the second half roller 602, when the rubber roller body 6 is installed, first align the first half roller 601 and the second half roller 602, and then fit them on the rotating shaft 3. At this time, the clamping blocks 7 on the first half roller 601 will be stuck into the clamping grooves 8 on the second half roller 602, and then rotate the bolts 11 to make the bolts 11 on the first half roller 601 rotate into the threaded grooves 9 on the second half roller 602, so that the first half roller 601 and the second half roller 602 are fixed together, so that it is more convenient to disassemble the rubber roller body 6 when it needs to be replaced, and it is also more convenient to install, and the number of rubber roller bodies 6 installed can be determined according to needs, so that multiple rubber roller bodies 6 can be installed on one rotating shaft 3 of the present device, thereby improving production efficiency.

[0025] A pair of sliding grooves 12 are formed in the outer side walls of the first half roller 601 and the second half roller 602; the inner side walls of the two pairs of sliding grooves 12 are both slidably connected with sliding blocks 13; one side of the outer walls of the two pairs of sliding blocks 13 is fixedly connected with a limiting plate 14, and the limiting plate 14 is in a semi-circular shape; one end of the outer walls of the first half roller 601 and the second half roller 602 is rotatably connected with a double threaded rod 15, and one end of the outer walls of a pair of double threaded rods 15 respectively penetrates through the two pairs of sliding blocks 13, and the pair of double threaded rods 15 are respectively threadedly connected with the two pairs of sliding blocks 13; one end of the outer walls of the pair of double threaded rods 15 is respectively rotatably connected to one side of the inner walls of the pair of sliding grooves 12. By rotating the double threaded rod 15, since the double threaded rod 15 is threadedly connected with the pair of sliding blocks 13, the rotation of the double threaded rod 15 will drive the pair of sliding blocks 13 to move towards the center or both sides simultaneously, so that the pair of sliding blocks 13 drive the pair of limiting plates 14 to move. Thus, by rotating the double threaded rods 15 on the first half roller 601 and the second half roller 602, the two pairs of limiting plates 14 can limit the packaging bags placed on the rubber roller body 6, so that the packaging bags are not easily displaced during punching, and thus the punching of the packaging bags is more accurate.

[0026] The double threaded rod 15 includes a circular rod 151 and a square rod 152; a first square groove 16 is formed at one end of the outer wall of the circular rod 151; the outer side wall of the square rod 152 is slidably connected to the inner side wall of the first square groove 16; a spring is fixedly connected to one side of the inner wall of the first square groove 16, and one end of the outer wall of the spring is fixedly connected to one end of the outer wall of the square rod 152; placing grooves 17 are formed at one end of the outer walls of the first half roller 601 and the second half roller 602, and the handles of the pair of square rods 152 are respectively located in the pair of placing grooves 17. Since the double threaded rod 15 includes the circular rod 151 and the square rod 152, when it is necessary to rotate the double threaded rod 15, the square rod 152 is pulled to make the square rod 152 slide in the first square groove 16 on the circular rod 151, so that the handle of the square rod 152 is located outside the first half roller 601. At this time, when the first square rod is rotated, the first square rod will drive the circular rod 151 to rotate, so that the double threaded rod 15 rotates, and thus the limiting plate 14 is adjusted. When it is not necessary to rotate the double threaded rod 15, the square rod 152 is released. At this time, the spring will drive the square rod 152 to reset, so that the handle of the square rod 152 is located in the placing groove 17. And since the bolts 11 for fixing the first half roller 601 and the second half roller 602 are also located in the square groove 10, the adjustment and installation mechanisms of the rubber roller body 6 are both located inside. Thus, when the rubber roller body 6 is running, it is not easy to affect the operation of other machines or equipment, and the fact that the adjustment and installation mechanisms of the rubber roller body 6 are both located inside also makes the rubber roller body 6 more beautiful.

[0027] A collecting shell 18 is fixedly connected to the inner side wall of the base 1, and the collecting shell 18 is located below the needle roller 4; a group of brushes 19 are fixedly connected to the top end of the outer wall of the collecting shell 18 through a square plate, and the group of brushes 19 are matched with the needle roller 4, and the brushes 19 are in contact with the needles of the needle roller 4. Due to the high-frequency and long-term needle pricking of the rubber roller body 6, the rubber roller body 6 is prone to falling slag and then being damaged. The device can collect the residues dropped by the rubber roller body 6 through the collecting shell 18, thereby avoiding the residues from running in the working environment. And through the brushes 19, the needles on the needle roller 4 will encounter the brushes 19 when rotating, so that the brushes 19 can clean the needles. Thus, the brushes 19 clean the residues adhered to the needles on the needle roller 4, thereby avoiding the influence of the adhered residues on the needle roller 4 on the punching operation of the packaging bag. Therefore, the device not only makes it more convenient to punch the packaging bag, but also makes it more convenient to replace the rubber roller body 6, and avoids the influence of the residues of the rubber roller body 6 on the punching of the packaging bag.

[0028] Working principle: By replacing the brush 19 with the rubber roller body 6, when the packaging bag is placed on the rubber roller body 6 for rolling punching, due to the relatively hard material of the rubber roller body 6, it is more convenient for the needle roller 4 to punch holes, and it is not easy for the needles on the needle roller 4 to fail to penetrate the packaging bag. Thus, it is more convenient for the packaging bag to perform the punching process, and the punching effect and quality are better. And because the rubber roller body 6 includes the first half roller 601 and the second half roller 602, when installing the rubber roller body 6, first align the first half roller 601 and the second half roller 602, and then fit them on the rotating shaft 3. At this time, the clamping block 7 on the first half roller 601 will snap into the clamping groove 8 on the second half roller 602, and then rotate the bolt 11 so that the bolt 11 on the first half roller 601 rotates into the threaded groove 9 on the second half roller 602, making the first half roller 601 and the second half roller 602 fixed together. Thus, it is more convenient to disassemble the rubber roller body 6 when it needs to be replaced, and it is also more convenient during installation. And the number of rubber roller bodies 6 installed can be determined according to requirements, so that multiple rubber roller bodies 6 can be installed on one rotating shaft 3 of this device, thereby improving production efficiency. And by rotating the double threaded rod 15, since the double threaded rod 15 is threadedly connected to a pair of sliding blocks 13, the rotation of the double threaded rod 15 will drive a pair of sliding blocks 13 to move towards the center or both sides simultaneously. Thus, a pair of sliding blocks 13 drive a pair of limiting plates 14 to move. Thus, by rotating the double threaded rod 15 on the first half roller 601 and the second half roller 602, the two pairs of limiting plates 14 can limit the packaging bag placed on the rubber roller body 6, making it not easy for the packaging bag to shift position during punching, so that the punching of the packaging bag is more precise. And because the double threaded rod 15 includes a circular rod 151 and a square rod 152, when it is necessary to rotate the double threaded rod 15, pull the square rod 152 so that the square rod 152 slides in the first square groove 16 on the circular rod 151, making the handle of the square rod 152 located outside the first half roller 601. At this time, rotate the first square rod, and the first square rod will drive the circular rod 151 to rotate, thus making the double threaded rod 15 rotate, and thus adjusting the limiting plate 14. When it is not necessary to rotate the double threaded rod 15, release the square rod 152. At this time, the spring will drive the square rod 152 to reset, making the handle of the square rod 152 located in the placement groove 17. And because the bolt 11 for fixing the first half roller 601 and the second half roller 602 is also located in the square groove 10, thus the adjustment and installation mechanisms of the rubber roller body 6 are both located inside, so that when the rubber roller body 6 is operating, it is not easy to affect the operation of other machinery or equipment. And the adjustment and installation mechanisms of the rubber roller body 6 being both located inside also make the rubber roller body 6 more beautiful. And because the rubber roller body 6 is pricked by needles at high frequency and for a long time, the rubber roller body 6 is prone to dropping slag and then being damaged. This device can collect the residues dropped by the rubber roller body 6 through the collection shell 18, thus avoiding the residues from affecting the working environment. And through the brush 19, when the needles on the needle roller 4 rotate, they will encounter the brush 19 and thus be cleaned by the brush 19,Thus, the brush 19 cleans the residues adhered to the needles on the needle roller 4, avoiding the influence of the adhered residues on the punching operation of the packaging bag. Therefore, this device not only makes it more convenient to punch the packaging bag, but also makes it more convenient to replace the rubber roller body 6, and avoids the influence of the residues on the rubber roller body 6 on the punching of the packaging bag.
