Description

Technical Field

[0001] The utility model relates to the technical field of paper tube processing and production, in particular to a paper tube paper rolling device. Background Art

[0002] The paper tube winding device is a device for winding kraft paper onto a paper tube.

[0003] The existing paper tube paper rolling device has the following problems when in use:

[0004] 1. The existing paper tube winding device needs to produce paper tubes first and then input the paper tubes into the device. However, during the transportation of the paper tubes, due to the large amount of paper scraps in the production environment, they are often covered on the surface of the paper tubes. At this time, when the paper roll is wrapped around the paper tube, it is easy to wrap up the debris, resulting in an uneven surface of the finished product, affecting the quality of the finished product.

[0005] 2. When the paper roll is wrapped around the paper tube, the paper roll is often glued to the surface of the paper tube so that the paper roll can be firmly attached to the surface of the paper tube. However, the existing device drips glue on the glue surface of the paper roll and then evenly spreads it to make the paper roll adhere to the surface of the paper tube. However, the size and width of the paper roll are different, and the glue dripping operation is prone to errors, resulting in too much or too little glue, which will affect the quality of the finished product.

DETAILED DESCRIPTION

[0035] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, a paper tube paper rolling device of this embodiment includes a base 1 and a paper tube 2 arranged on the base 1;

[0037] The paper tube 2 is provided with a feeding assembly 3 disposed above the base 1 and arranged in sequence from right to left along the base 1 for making the paper tube 2 rotate axially and slide toward the left side of the base 1, a cleaning assembly 4 for cleaning debris on the surface of the paper tube 2, a feeding assembly 5 for forming a protective film on the outer wall of the paper tube 2, and a cutting assembly 6 for cutting the paper tube 2;

[0038] The feeding assembly 3 comprises two rolling rods 31 rotatably arranged on the base 1 and abutting against both sides of the lower outer wall of the paper tube 2, two roller brackets 32 arranged on both sides of the upper part of the paper tube 2 and fixedly connected to the base 1, and a plurality of rolling wheels 33 arranged rotatably in the roller brackets 32;

[0039] The rolling rod 31 is arranged along the length direction of the base 1 and rotates axially along its central axis. The rolling wheel 33 abuts against the outer wall of the paper tube 2 and generates a thrust force on the paper tube 2 toward the left side of the base 1.

[0040] The cleaning assembly 4 includes a plurality of fixed brackets 41 arranged along the length direction of the base 1 and detachably connected to the base 1 at both ends, and a cleaning brush 42 arranged in the middle of the fixed brackets 41 and abutting against the outer wall of the paper tube 2;

[0041] The middle section of the fixed bracket 41 is arranged to wrap the upper part of the paper tube 2;

[0042] The feeding assembly 5 comprises two paper strips 51 slidably arranged on one side of the base 1 and the front ends of which are respectively glued to the paper tube 2 and completely wrap the paper tube 2, a gluing subassembly 52 arranged at the rear end of the paper strips 51 and fixedly connected to the base 1, and two tensioning rods 53 arranged in the middle of the paper strips 51 and used to adjust the tension of the front ends of each paper strip 51;

[0043] Two tension rods 53 are arranged in an interval arrangement along the height direction of the base 1, and the lower side of each tension rod 53 abuts against the drying surface of a corresponding paper strip 51;

[0044] A threaded rod 7 is fixedly provided at the base 1 in the middle section of the paper roll 51 along the height direction of the base 1, and two tension rods 53 are slidably provided along the height direction of the threaded rod 7;

[0045] The cutting assembly 6 includes a first slide 61 slidably arranged along the length direction of the base 1, two second slides 62 arranged on both sides of the paper tube 2 and slidably arranged along the front-rear direction of the first slide 61, and a cutting blade 63 detachably connected to the second slide 62 and extending out from each second slide 62 on one side close to the central axis of the paper tube 2.

[0046] When the product is in use, the front end of the paper tube 2 is placed along the right end of the base 1, and the device is started to rotate the rolling rod 31 axially and the rolling wheel 33 rotates, thereby driving the paper tube 2 to slide toward the left end of the base 1 and rotate along its own central axis. When the paper tube 2 slides to the cleaning component 4, the cleaning brush 42 abuts against the outer wall of the paper tube 2. As the paper tube 2 moves, the outer wall of the paper tube 2 is swept by the cleaning brush 42 at all places, thereby separating the debris on the outer wall of the paper tube 2 from the paper tube 2 and accumulating on one side of the cleaning brush 42. By regularly removing and cleaning the cleaning brush 42 and then installing it, it is ensured that there is no debris on the surface of the paper tube 2 after passing through the cleaning component 4, and the clean effect is maintained, and then the next winding operation is carried out, thereby solving the problem that there are often debris on the surface of the paper tube when winding the roll of paper.

[0047] When the product is in use, glue is poured into the gluing subassembly 52, and each paper strip 51 is slid through the gluing subassembly 52, so that the glue-coated surface of the paper strip 51 is evenly coated with glue, and then the paper strip 51 is adhered to the outer wall of the paper tube 2, completely wrapping the outer wall of the paper tube 2, and each paper strip 51 is pressed by the tensioning rod 53, so that the paper strip 51 is kept in a taut state by the pressure of the tensioning rod 53, and then is wound around the paper tube 2, thereby preventing the paper strip 51 from loosening and causing partial stacking of the winding position.

[0048] When the product is in use, when the paper tube 2 with its outer wall wrapped around by the feeding component 5 moves to the cutting component 6, when the paper tube 2 is inserted into the cutting component 6 to the required length, the first slide 61 slides to the cutting position and slides to the left with the paper tube 2, and the second slide 62 slides toward the central axis of the paper tube 2, so that the cutting blade 63 contacts the outer wall of the paper tube 2 and cuts off the finished part of the paper tube 2, completing the production of a section of the finished product, so that the finished paper tube 2 sections of the appropriate length can be cut as needed.

[0049] like Figure 1 and Figure 3 As shown, mounting parts 8 are arranged on the side of the base 1 corresponding to each fixed bracket 41, and abutment plates 411 are provided at both ends of the fixed bracket 41 to wrap the front and rear sides of the upper part of the mounting part 8. A first threaded hole 9 is penetrated through the upper part of the mounting part 8 and the abutment plate 411 along the thickness direction of the mounting part 8, and a first fastening screw 10 is detachably connected in the first threaded hole 9.

[0050] When the product is in use, the operator regularly observes the edge of the cleaning brush 42 to determine whether the blocked debris has reached an upper limit. When the upper limit is reached, the operator removes the first fastening screws 10 at both ends of the single fixed bracket 41, picks up the fixed bracket 41, cleans the cleaning brush 42, and then puts the fixed bracket 41 back so that the abutment plate 411 abuts against the two sides of the upper end of the corresponding mounting portion 8, and then inserts the first fastening screw 10 into the first threaded hole 9 to fasten the installation, thereby solving the problem that the cleaning brush 42 blocks too much debris, causing some debris to break away from the cleaning brush and move with the paper tube 2.

[0051] like Figure 1 and Figure 6 As shown, the gluing subassembly 52 includes a feeding channel 521 fixedly connected to the base 1 and arranged along the length direction of the paper strip 51, a glue holding chamber 522 arranged at the rear end of the feeding channel 521, a gluing roller 523 rotatably arranged in the glue holding chamber 522 and with the upper part extending out of the glue holding chamber 522 to abut against the gluing surface of the paper strip 51, and a clamping rod 524 fixedly arranged in the middle section of the feeding channel 521 to abut against the dry surface of the paper strip 51 and make the paper strip 51 completely fit the upper part of the gluing roller 523.

[0052] When the product is in use, the operator pours glue into the glue chamber 522 and starts the motor to drive the glue roller 523 to rotate, so that the surface of the glue roller 523 is covered with glue, and the front end of each paper roll 51 is pulled through the glue roller 523. After the glue-coated surface of the paper roll 51 is evenly stained with glue, the paper roll 51 is pulled through the clamping rod 524 and passes through the feeding assembly 5 along the lower part of the corresponding tensioning rod 53 and fits with the paper tube 2. As the paper tube 2 moves, it is continuously pulled to drive the paper roll 51 to slide out, so that when the paper roll 51 slides through the glue roller 523, the glue-coated surface is evenly covered with a layer of glue, which saves the operation of leveling glue and ensures that the amount of glue on each paper roll 51 is uniform, thereby improving the yield rate of the finished product of the device.

[0053] like Figure 6 As shown, a heating rod 11 is disposed in the glue holding cavity 522 .

[0054] When the product is used, after pouring glue into the glue chamber 522, the heating rod 11 is turned on to heat the glue, thereby keeping the glue in a liquid flowing and thick state to prevent the glue from cooling and reducing its adhesion.

[0055] like Figure 1 , Figure 4 and Figure 5 As shown, a sliding sleeve 12 is fixedly provided at one end of the two tensioning rods 53, and the sliding sleeve 12 is slidably sleeved on the threaded rod 7. A limiting track 71 is provided on the outer wall of the threaded rod 7 along the height direction of the threaded rod 7, and a limiting block 121 is provided on the inner wall of the sliding sleeve 12 and is embedded in the limiting track 71 and slides;

[0056] The upper and lower ends of the sliding sleeve 12 are respectively provided with tightening sleeves 13 , which are threadedly connected to the threaded rod 7 and abut against the upper and lower ends of the tightening sleeve 13 .

[0057] When the product is in use, the tightening sleeve 13 is screwed to a position away from the sliding sleeve 12, and then the sliding sleeve 12 is slid to each tensioning rod 53 to press the corresponding paper strip 51 to produce a stretching and tensioning effect on the paper strip 51, and then the tightening sleeves 13 on the upper and lower sides are rotated to abut against the two ends of the sliding sleeve 12. During the sliding process of the sliding sleeve 12, the limit block 121 is always in the limit track 71, thereby ensuring that the direction of the tensioning rod 53 remains unchanged, thereby solving the problem of friction driving the tensioning rod 53 to rotate left and right during the sliding process of the paper strip 51, resulting in loss of tensioning effect.

[0058] like Figure 1 and Figure 7As shown, the cutting blade 63 is provided with matching holes 14 on the upper and lower sides respectively, and the second slide seat 62 is provided with a second threaded hole 15 corresponding to the matching hole 14 and penetrating the thickness direction of the second slide seat 62, and the second slide seat 62 is detachably connected with a second fastening screw 16 that passes through the matching hole 14 along one side of the second threaded hole 15 and passes through the second threaded hole 15 along the other side.

[0059] When the product is in use, if the cutting blade 63 is damaged after long-term use, the second fastening screw 16 is removed, the cutting blade 63 is taken out, and after replacement, the matching holes 14 are aligned with the corresponding second threaded holes 15, and then the second fastening screw 16 is tightened, thereby completing the convenient replacement. When a single cutting blade 63 is replaced, the other cutting blade 63 can independently complete the cutting operation without affecting the efficiency of the work process.

[0060] The working principle of this device is:

[0061] Step 1: Place the front end of the paper tube 2 along the right end of the base 1, start the device, make the rolling rod 31 rotate axially, and the rolling wheel 33 rotate, thereby driving the paper tube 2 to slide toward the left end of the base 1 and rotate along its own central axis.

[0062] Step 2: When the paper tube 2 slides to the cleaning component 4, the cleaning brush 42 contacts the outer wall of the paper tube 2. As the paper tube 2 moves, all parts of the outer wall of the paper tube 2 are swept by the cleaning brush 42, thereby removing the debris on the outer wall of the paper tube 2 from the paper tube 2.

[0063] Step 3: Pour glue into the glue chamber 522, and turn on the heating rod 11 to keep the glue in the glue chamber 522 in a liquid viscous state, and start the glue roller 523 so that the surface of the glue roller 523 is always covered with glue.

[0064] Step 4: Pull the front end of each paper strip 51 through the gluing roller 523, so that the glue-coated surface of the paper strip 51 is evenly stained with glue, then pull the paper strip 51 through the clamping rod 524 and along the lower part of the corresponding tensioning rod 53 to pass through the feeding assembly 5 and fit with the paper tube 2. As the paper tube 2 moves, it is continuously pulled to drive the paper strip 51 to slide out.

[0065] Step 5: Twist the tightening sleeve 13 away from the sliding sleeve 12, and then slide the sliding sleeve 12 until each tensioning rod 53 presses the corresponding paper strip 51 to produce a stretching and tensioning effect on the paper strip 51, and then rotate the tightening sleeves 13 on the upper and lower sides to abut against the two ends of the sliding sleeve 12.

[0066] Step 6: When the paper tube 2 wrapped around the outer wall by the feeding component 5 moves to the cutting component 6, when the paper tube 2 is inserted into the cutting component 6 to the required length, the first slide 61 slides to the cutting position and slides to the left with the paper tube 2, and the second slide 62 slides toward the central axis of the paper tube 2, so that the cutting blade 63 contacts the outer wall of the paper tube 2, and cuts off the finished part of the paper tube 2, completing the production of a section of the finished product.

[0067] The above description is only a specific implementation method of the utility model, and does not limit the patent scope of the utility model. Any equivalent structural transformation made using the contents of the utility model specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the utility model.
