Description

Technical Field

[0001] The utility model belongs to the technical field of paper barrel processing, in particular to a paper barrel roll edge forming device. Background Art

[0002] In recent years, paper barrels have been increasingly used in the markets of welding wire, electrical wire, food, asphalt, etc., especially in the markets of specialty chemicals, food, and asphalt. Paper barrels can be divided into three levels according to their uses. Level 1 barrels are used for export and transportation packaging of valuables, level 2 barrels are mainly used for transportation packaging of domestic products, and level 3 barrels are mainly used for transportation packaging of short-distance and cheap goods.

[0003] Paper barrels are manufactured by cutting, gluing, rolling and pressing paper tightly. When rolling paper, the paper is too thin to be fixed on the paper roll and is easily deformed. Secondly, in order to ensure the hardness of the finished paper barrel, kraft paper is often used as the raw material. When rolling paper, it is inevitable that kraft paper will rub against the device to produce paper powder and paper scraps. Paper powder and paper scraps are easy to adhere to the glue, thus affecting the firmness of the paper barrel.

[0004] The Chinese patent with the authorization announcement number CN213798383U discloses a paper barrel roll edge forming device, including a first leg and a U-shaped plate, a paper roll roller is fixedly connected to the left side of the connecting rod, an air hole is arranged on the outer wall of the paper roll roller on the right side, a connecting pipe is rotatably connected to the right side of the connecting rod through the first bearing, a vacuum pump is fixedly connected to the other end of the connecting pipe, the bottom of the U-shaped plate is slidably connected to the first slide rod through a slider, a connecting block is fixedly connected to the left side of the bottom of the U-shaped plate through a slider, and a hydraulic press is fixedly connected to the left side of the first leg. The vacuum pump extracts the internal gas inside the paper roll roller, and the air hole sucks air inward and tightens the paper to prevent the paper from wrinkling or being squeezed and deformed to affect the shape of the paper barrel, the hydraulic press pushes the U-shaped plate to slide to the left, and the limit block on the top of the U-shaped plate drives the formed paper barrel to move to the left to the left side of the paper roll roller to cooperate with the clamping roller to achieve clamping, providing space for the paper roll roller to continue working, and the forming and clamping are carried out simultaneously, which improves the work efficiency.

[0005] However, the above has the following shortcomings:

[0006] When the above patent is performing the edge rolling process, there will be continuous friction and extrusion between the paper material and the U-shaped plate and the pressure roller. Long-term continuous work will produce a large amount of paper powder and paper scraps, which are easy to adhere to the glue and affect the firmness of the paper barrel bonding.

[0007] After the paper dust and paper scraps are generated in the above-mentioned patent, the paper dust and paper scraps are easily sucked into the pores, causing the pores to be blocked and affecting the suction effect on the paper material.

[0008] In order to facilitate the removal of the formed paper barrel, the above patent has an axle seat only at one end of the paper reel. Long-term operation may easily lead to an imbalance in the rotation of the paper reel, affect the quality of the roll edge processing, and even damage the paper reel and the bearing.

DETAILED DESCRIPTION

[0033] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0034] Embodiment 1:

[0035] like Figure 1-7As shown, a paper barrel roll edge forming device includes a first bracket 10, the upper end of the first bracket 10 is rotatably connected to an internally hollow paper roll 13, a plurality of through-holes 33 are evenly distributed on the paper roll 13, a feeding component is arranged on one side of the paper roll 13 at the corresponding position of the pores 33, and the end of the paper roll 13 extending out of the first bracket 10 away from the pores 33 is transmission-connected to a planetary gear set 34, the power input end of the planetary gear set 34 is transmission-connected to the end of the paper roll 13 extending out of the first bracket 10, and the power input end of the planetary gear set 34 is transmission-connected to the end of the paper roll 13 extending out of the first bracket 10, and the power input end of the planetary gear set 34 is transmission-connected to the end of the paper roll 13 extending out of the first bracket 10. The output end is coaxial with the paper winding roller 13 and rotates relatively thereto. The power output end of the planetary gear set 34 is drivingly connected to the fan 20. The first bracket 10 is fixedly connected to a lower wind hood 16 that fits tightly with the feeding component. The upper side of the feeding component is rotatably connected to an upper wind hood 17 that is combined with the lower wind hood 16 to form a complete cylindrical shape. The end of the paper winding roller 13 extending out of the fan component is fixedly connected to a counterweight wheel 21. A second bracket 11 is provided on one side of the end of the paper winding roller 13 away from the counterweight wheel 21. The upper end of the second bracket 11 is rotatably connected to a clamping roller 12 close to the paper winding roller 13.

[0036] The fan 20 is driven to rotate at high speed while driving the paper roll 13 to rotate, and cooperates with the lower wind cover 16 and the upper wind cover 17 to form an airflow outside the paper roll 13, so as to blow away the generated paper powder and paper scraps in time to prevent the paper scraps from adhering to the glue and affecting the bonding firmness.

[0037] The counterweight wheel 21 rotates together with the paper winding roller 13 to balance the weight of the paper winding roller 13, thereby improving the stability of the device in the paper edge processing.

[0038] like Figure 1-7 As shown, the feeding component includes a storage table 29, one side of the storage table 29 extends into the downwind hood 16 and is fixedly connected to the downwind hood 16, the upper side of the paper roller 13 is fixedly connected to a feed shell 19, a feed wheel 35 is rotatably connected between the two sides of the feed shell 19, and one end of the feed wheel 35 extending out of the feed shell 19 is transmission-connected to a third motor 36.

[0039] like Figure 1-7 As shown, the bottom of the first bracket 10 is located below the counterweight wheel 21 and is fixedly connected to a fourth bracket 24. The upper end of the fourth bracket 24 is rotatably connected to a pulley 23. One end of the pulley 23 extending out of the fourth bracket 24 is transmission-connected to a second motor 25. The pulley 23 and the counterweight wheel 21 are transmission-connected via a transmission belt 22.

[0040] like Figure 1-7 As shown, a plurality of slide grooves 37 are evenly distributed in the circumferential direction in the counterweight wheel 21, a counterweight block 38 is slidably connected in each slide groove 37, a group of adjustment grooves 39 are opened on both sides of each slide groove 37 in the counterweight wheel 21, and a fastening bolt 40 fixedly connected to the counterweight block 38 is fixedly connected in each adjustment groove 39.

[0041] By adjusting each counterweight block 38, the rotation balance between the paper winding roller 13 and the counterweight wheel 21 is ensured, the stability of the device in the paper edge processing is improved, and the service life of the device is increased.

[0042] like Figure 1-7 As shown, a vacuum pump 26 is fixedly connected to the bottom of the first bracket 10, a solenoid valve 27 is fixedly connected to the upper side of the vacuum pump 26, an air duct 28 is fixedly connected to the upper end of the solenoid valve 27, and an end of the air duct 28 away from the solenoid valve 27 is rotatably connected to an end of the paper roller 13 extending out of the counterweight wheel 21.

[0043] like Figure 1-7 As shown, the pushing component includes a sliding rod 31, which is fixedly connected to the side of the first bracket 10 away from the counterweight wheel 21, and the end of the sliding rod 31 away from the first bracket 10 is fixedly connected to the third bracket 18, and a screw 30 is rotatably connected between the third bracket 18 and the first bracket 10, and the end of the screw 30 extending out of the third bracket 18 is transmission-connected to the first motor 15, and a support plate 14 is slidably connected to the sliding rod 31 and is meshed and transmission-connected with the screw 30.

[0044] In this embodiment, the operator starts the device, the second motor 25 drives the counterweight wheel 21 to rotate the paper roller 13, the operator places the cut and glued paper on the storage table 29, the third motor 36 drives the feeding wheel 35 to rotate, so that the paper is stably moved in the direction of the paper roller 13, the vacuum pump 26 continuously extracts the air inside the paper roller 13, so as to form suction at the air hole 33, and the suction at the air hole 33 is used to tightly adsorb the paper on the surface of the paper roller 13. Under the rotation of the paper roller 13, the paper is rolled up and bonded to form the prototype of the paper barrel.

[0045] Then, the first motor 15 is started, so that the screw 30 drives the support plate 14 to move, and the support plate 14 pushes the prototype of the paper barrel to move toward the pressing roller 12. When the prototype of the paper barrel contacts the pressing roller 12, the pressing roller 12 rotates in coordination with the rotation of the paper reel 13, and a finished paper barrel is obtained after compaction. Then, the support plate 14 continues to push the paper barrel to move until the paper barrel falls off the paper reel 13 and the support plate 14 resets and returns to the position corresponding to the air hole 33.

[0046] While the reeling process is being carried out, the fan 20 rotates along with the rotation of the paper reel 13, and by utilizing the characteristics of the planetary gear set 34, the rotation speed of the fan 20 is made higher than the rotation speed of the paper reel 13, and in conjunction with the cylindrical lower wind hood 16 and the upper wind hood 17, an annular airflow is formed on the outside of the paper reel 13, so that the paper powder and paper scraps generated by the friction between the paper material and the device are blown away in time.

[0047] When the paper winding roller 13 rotates, the counterweight wheel 21 rotates together with it. The counterweight wheel 21 is made of a material with large mass and uniform texture, and the mass of the counterweight wheel 21 is consistent with the mass of one end of the paper winding roller 13 that performs the edge rolling work. During the rotation of the paper winding roller 13, the counterweight wheel 21 plays a role in balancing the weight of the paper winding roller 13 to prevent one end of the paper winding roller 13 from being unsupported. After long-term rotation, the paper winding roller 13 and the bearing will be damaged, resulting in radial runout, which affects the quality of the edge rolling processing.

[0048] At the same time, due to the problem of processing accuracy, the paper roller 13 will inevitably jump due to uneven mass distribution during the rotation process. At this time, according to the rotation state of the paper roller 13, the operator loosens the corresponding fastening bolts 40, and then adjusts the position of the corresponding counterweight block 38 in the slide groove 37, thereby adjusting the dynamic balance between the counterweight wheel 21 and the paper roller 13, avoiding the jumping of the paper roller 13, improving the stability of the roll edge processing, and effectively improving the service life of the device.

[0049] Embodiment 2:

[0050] like Figure 1-7 As shown, the pushing component includes a sliding rod 31, which is fixedly connected to the side of the first bracket 10 away from the counterweight wheel 21, and the end of the sliding rod 31 away from the first bracket 10 is fixedly connected to the third bracket 18, and a screw 30 is rotatably connected between the third bracket 18 and the first bracket 10, and the end of the screw 30 extending out of the third bracket 18 is transmission-connected to the first motor 15, and a support plate 14 is slidably connected to the sliding rod 31 and is meshed and transmission-connected with the screw 30.

[0051] like Figure 1-7 As shown, a sealing plug 32 for blocking the end opening of the paper winding roller 13 is fixedly connected to one end of the supporting plate 14 away from the first bracket 10 .

[0052] As a further embodiment, when the support plate 14 pushes the prototype of the paper barrel to leave the range of the air hole 33, the air hole 33 is exposed to the outside, and paper dust and scraps are easily sucked in, causing the air hole 33 to be blocked. At this time, the solenoid valve 27 is controlled to disconnect the connection between the air duct 28 and the vacuum pump 26, and suction is no longer generated at the air hole 33 to prevent paper dust from being sucked in. At the same time, the sealing plug 32 no longer blocks the opening at the end of the paper roll 13 as the support plate 14 moves, so that the inside of the paper roll 13 is connected to the outside. Since the fan 20 forms a high-speed airflow on the outside of the paper roll 13, due to the Bernoulli principle, a low pressure is formed on the surface of the paper roll 13, so that an airflow from the inside to the outside is formed at the air hole 33, and the air is blown out from the air hole 33 to further prevent the paper dust from blocking the air hole 33, and can clean the air hole 33. After the support plate 14 is reset, the sealing plug 32 blocks the paper roll 13 again, and the solenoid valve 27 connects the air duct 28 with the vacuum pump 26 again to restore the suction at the air hole 33.
