Description

Technical Field

[0001] This invention relates to the field of hoisting technology, and more particularly to a paper roller hoisting machine. Background Technology

[0002] With the rapid development of the paper industry, improving production efficiency and logistics efficiency has become one of the key factors in industry competition. As the main product form of the paper industry, paper rolls have higher requirements for the efficiency, safety and accuracy of loading and unloading equipment in handling, storage and transportation. Against this background, paper roll hoisting machines have emerged and play an indispensable role in the modern paper industry.

[0003] Nowadays, after paper is formed, it is usually rolled up using paper rollers. After the paper is rolled up on the paper rollers, a lifting device is used to lift and move the paper rollers. However, after the paper is rolled up on the paper rollers, the end of the roll is affected by the cutting device, resulting in an uneven or slightly tilted end. Therefore, to facilitate the subsequent cutting and processing of the roll, workers usually use a cutting device to cut off the uneven part of the end of the roll before the lifting device lifts and moves the paper rollers, and then fix the end of the roll to prevent it from becoming loose when the lifting device lifts and moves the paper rollers. However, manually cutting and fixing the end of the roll requires close proximity to the roll, which poses a high safety hazard and is less safe. Moreover, manual operation consumes a lot of time and manpower, resulting in low efficiency. Summary of the Invention

[0004] In view of this, the present invention provides a paper roll hoisting machine, which can solve the shortcomings of the prior art in cutting and fixing the end of the paper roll, which requires manual operation close to the paper roll, resulting in low safety, time and labor costs, and low efficiency.

[0005] The technical implementation scheme of the present invention is as follows: A paper roller hoisting machine includes a hoisting frame, an arc-shaped guide rail, an arc-shaped rack I, a connecting frame, an electric slide rail, a cutter I, a cutter II, a drag-reducing wheel, a fixing mechanism, a rotating mechanism, a feeding mechanism, and a cutting mechanism. Two arc-shaped guide rails are symmetrically connected to the lower end of the hoisting frame. The arc-shaped rack I is rotatably connected to the arc-shaped guide rail. The connecting frame is connected to the arc-shaped rack I. The electric slide rail is connected to the connecting frame. The cutter I is slidably connected to one side of the connecting frame and is connected to the slider of one side of the electric slide rail. The cutter II is slidably connected to the other side of the connecting frame and is connected to the slider of the other side of the electric slide rail. The drag-reducing wheel is rotatably connected to... Within the cutter I, the fixing mechanism is used to fix the paper roll on the lifting frame, enabling the lifting frame to lift and move the paper roll. The rotating mechanism is used to drive the arc-shaped rack I to rotate, allowing the cutter I and the cutter II to rotate in opposite directions on the paper roll. This allows the cutter I and the cutter II to cut off the uneven part at the end of the paper roll when they converge again. The feeding mechanism is used to feed the tape and attach one end of the tape to the end of the paper roll. Then, the rotating mechanism again causes the cutter I and the cutter II to rotate synchronously on the paper roll, pulling the other end of the tape past the end of the paper roll and attaching it to the paper roll, thus fixing the end of the paper roll. The cutting mechanism is used to cut off the portion of the tape that has been pulled out.

[0006] More preferably, the rotating mechanism includes a servo motor I and a gear I, with several servo motors I symmetrically connected to the lower end of the hoisting frame, and the gear I connected to the output shaft of the servo motor I, and the gear I meshing with the arc-shaped rack I, so that the servo motor I can drive the arc-shaped rack I to rotate.

[0007] More preferably, the fixing mechanism includes a servo motor II, a gear II, and an arc-shaped rack II. Two servo motors II are symmetrically connected to the lower end of the lifting frame. The gear II is connected to the output shaft of the servo motor II. Two arc-shaped racks II are symmetrically rotatably connected to the lower end of the lifting frame, and the arc-shaped racks II mesh with the gear II, so that the servo motor II can drive the arc-shaped racks II to rotate, thereby locking the paper roller at the lower end of the lifting frame.

[0008] More preferably, the feeding mechanism includes a connecting block, an electric push rod, a connecting frame, and a feeding rod. Several connecting blocks are spaced apart and connected to the cutter II. The electric push rod is connected to the connecting block. The connecting frame is connected to the telescopic rod of the electric push rod. The feeding rod is connected to the connecting frame, and the feeding rod is used for feeding tape.

[0009] More preferably, the feeding mechanism further includes a knob, which is threaded onto the feeding rod, and the knob is used to limit the tape on the feeding rod.

[0010] More preferably, the feeding mechanism further includes a fixed frame, a guide wheel, a movable frame, an adhesive wheel, and a spring. The fixed frame is connected to the connecting frame, the guide wheel is rotatably connected to the fixed frame and is used to guide the tape, the movable frame is slidably connected to the connecting frame, and the adhesive wheel is rotatably connected to the movable frame and is used to stick the end of the tape. Then, the connecting frame is driven by the electric push rod to move closer to the roll of paper, so that the movable frame and the adhesive wheel follow the movement of the connecting frame and stick the end of the tape to the end of the roll of paper. The two ends of the spring are respectively connected to the movable frame and the connecting frame.

[0011] More preferably, the cutting mechanism includes an electric roller, an annular column, and a cutter III. The electric roller is mounted on the connecting frame, the annular column is connected to the outer wall of the electric roller, and the cutter III is connected to the outer wall of the annular column. The cutter III is used to cut the tape.

[0012] More preferably, it also includes a positioning mechanism, which includes a laser sensing component, a sensing block, and a Hall effect sensing component. The laser sensing component is connected to the cutter I and is used to sense the tail end of the paper roll, thereby positioning the endpoint of the cutter I's rotation on the paper roll. The sensing block is mounted on the cutter I, and the Hall effect sensing component is mounted on the connecting frame on the same side as the cutter II. The Hall effect sensing component and the sensing block cooperate to position the endpoint of the cutter II's rotation on the paper roll.

[0013] Compared with the prior art, the present invention has the following advantages: 1. The present invention, through the cooperation of cutter I, cutter II and rotating mechanism, can automatically cut off the uneven part of the end of the paper roll. Then, through the cooperation of feeding mechanism and cutting mechanism, it can automatically use tape to stick and fix the end of the paper roll. After that, the paper roll is fixed on the lifting frame by the fixing mechanism, so that the paper roll can be lifted and moved together with the lifting frame. The whole operation process not only does not require personnel to approach the paper roll, which is safe, but also saves time and effort and has high efficiency.

[0014] 2. By setting a drag-reducing wheel, the present invention can reduce the friction between the cutter I and the paper roll when the cutter I moves on the surface of the paper roll, thereby protecting the surface of the paper roll.

This invention, through the cooperation of a laser sensing component, a sensing block, and a Hall effect sensing component, can automatically locate the endpoint of the rotation of cutter I and cutter II on the paper roll, thereby assisting people in operation and making it more convenient for people to use.

[0028] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, lateral, etc., also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0029] Example: A paper roll hoisting machine, see below Figures 1-10 As shown, it includes a lifting frame 1; the lifting frame 1 has three round holes on its upper side so that the hook of the lifting device can hook onto the lifting frame 1 through the round holes, thereby driving the lifting frame 1 to lift and move; it also includes an arc-shaped guide rail 2, an arc-shaped rack I 3, a connecting frame 4, an electric slide rail 5, a cutter I 6, a cutter II 7, a drag-reducing wheel 8, a fixing mechanism, a rotating mechanism, a feeding mechanism, and a cutting mechanism; two arc-shaped guide rails 2 are symmetrically connected to the lower end of the lifting frame 1; the arc-shaped rack I 3 is rotatably connected to the arc-shaped guide rail 2; the connecting frame 4 is connected to the arc-shaped rack. On frame I3, connecting frame 4 can rotate synchronously with the arc-shaped rack I3; electric slide rail 5 is connected to connecting frame 4; cutter I6 is slidably connected to the rear connecting frame 4, and cutter I6 is connected to the slider of the rear electric slide rail 5, so that the rear electric slide rail 5 can drive cutter I6 to move; cutter II7 is slidably connected to the front connecting frame 4, and cutter II7 is connected to the slider of the front electric slide rail 5, so that the front electric slide rail 5 can drive cutter II7 to move; drag reducing wheel 8 is rotatably connected inside cutter I6, so that... When cutter I6 moves on the surface of paper roll 102, the drag-reducing wheel 8 can reduce the friction between cutter I6 and the surface of paper roll 102; the fixing mechanism is used to fix paper roll 101 on the lifting frame 1, so that the lifting frame 1 can drive paper roll 101 to be lifted and moved; the rotating mechanism is used to drive arc rack I3 to rotate, so that arc rack I3 drives connecting frame 4, cutter I6 and cutter II7 to rotate, so that cutter I6 and cutter II7 can rotate in opposite directions on paper roll 102, thereby making cutter I6... When the cutter II 7 converges again, it can cut off the uneven part at the end of the roll paper 102; the feeding mechanism is used to feed the tape 103 and attach one end of the tape 103 to the end of the roll paper 102. Then, the rotating mechanism makes the cutter I 6 and cutter II 7 rotate synchronously on the roll paper 102, thereby pulling the other end of the tape 103 past the end of the roll paper 102 and attaching it to the roll paper 102, thus fixing the end of the roll paper 102; the cutting mechanism is used to cut off the part of the tape 103 that has been pulled out.

[0030] See Figure 3 and Figure 4As shown, the rotating mechanism includes servo motors I9 and gears I10; four servo motors I9 are symmetrically connected to the lower end of the lifting frame 1; four gears I10 are respectively connected to the output shafts of the four servo motors I9, and the two front gears I10 mesh with the front arc rack I3, while the two rear gears I10 mesh with the rear arc rack I3, so that the servo motors I9 can drive the arc rack I3 to rotate. Furthermore, by setting two gears I10 to mesh with one arc rack I3, the arc rack I3 can continue to rotate using the other gear I10 after disengaging from one gear I10, thereby increasing the rotation angle of the arc rack I3.

[0031] See Figure 5 and Figure 6 As shown, the fixing mechanism includes a servo motor II11, a gear II12, and an arc-shaped rack II13; two servo motors II11 are symmetrically connected to the lower end of the lifting frame 1; two gears II12 are respectively connected to the output shafts of the two servo motors II11, and two arc-shaped racks II13 are symmetrically rotatably connected to the lower end of the lifting frame 1, and the arc-shaped racks II13 mesh with the gears II12, so that the servo motors II11 can drive the arc-shaped racks II13 to rotate, thereby locking the paper roller 101 to the lower end of the lifting frame 1, thus fixing the paper roller 101 on the lifting frame 1.

[0032] See Figures 7-9As shown, the feeding mechanism includes connecting blocks 14, electric push rods 15, connecting frames 16, feeding rods 17, knobs 18, fixing frames 19, guide wheels 20, movable frames 21, adhesive wheels 22, and springs 23; four connecting blocks 14 are spaced apart and connected to the top of the cutter II 7; four electric push rods 15 are respectively connected to the four connecting blocks 14; four connecting frames 16 are respectively connected to the telescopic rods of the four electric push rods 15, and the frontmost and rearmost connecting frames 16 are shorter than the two middle connecting frames 16; feeding rods 17 are connected to the three rear connecting frames 16, and the feeding rods 17 are used to feed the tape 103; knobs 18 are threadedly connected to the feeding rods 17, and knobs 18 are used to limit the tape 103 on the feeding rods 17; two adjacent front and rear... Each connecting frame 16 is connected to a fixed frame 19, and there are three fixed frames 19. Guide wheels 20 are rotatably connected to the fixed frames 19 and are used to guide the tape 103. Each pair of adjacent connecting frames 16 is slidably connected to a movable frame 21, and there are three movable frames 21. Adhesive wheels 22 are rotatably connected to the movable frames 21, and the outer wall of the adhesive wheels 22 is coated with adhesive paint so that the adhesive wheels 22 can stick the end of the tape 103. Then, the connecting frame 16 is driven by the electric push rod 15 to move closer to the roll paper 102, so that the movable frames 21 and adhesive wheels 22 follow the connecting frame 16 and stick the end of the tape 103 to the end of the roll paper 102. The two ends of the spring 23 are respectively connected to the movable frames 21 and the connecting frames 16.

[0033] See Figure 7 , Figure 8 and Figure 10 As shown, the cutting mechanism includes an electric roller 24, an annular column 25, and a cutter III 26. An electric roller 24 is installed between two adjacent connecting frames 16, and the number of electric rollers 24 is three. The annular column 25 is sleeved on the outer wall of the electric roller 24, allowing the electric roller 24 to drive the annular column 25 to rotate. The outer wall of the annular column 25 is coated with an anti-adhesion coating to prevent the tape 103 from sticking to the outer wall of the annular column 25. The cutter III 26 is connected to the outer wall of the annular column 25 and protrudes from the outer wall of the annular column 25 so that the cutter III 26 can contact the tape 103 on the outer wall of the annular column 25, thereby cutting the tape 103 on the outer wall of the annular column 25.

[0034] In use, turn knob 18 off the feeding rod 17, then place the entire roll of tape 103 onto the feeding rod 17 for feeding. Then, turn knob 18 back onto the feeding rod 17 to limit the tape 103 on the feeding rod 17. Next, pull the first end of the tape 103 through the guide wheel 20 and the annular post 25, ensuring the adhesive side of the tape 103 faces the annular post 25 and the non-adhesive side faces the guide wheel 20. Then, pull the first end of the tape 103 through the adhesive wheel 22 and the annular post 25. Finally, use the adhesive wheel 22... The first end of the tape 103 is stuck together. During this process, when the first end of the tape 103 passes between the adhesive wheel 22 and the annular post 25, the tape 103 will squeeze the adhesive wheel 22 and the movable frame 21 to move away from the annular post 25. The spring 23 is stretched. At this time, under the elastic force of the spring 23, the spring 23 will drive the movable frame 21 and the adhesive wheel 22 to squeeze the tape 103, so that the adhesive side of the tape 103 is tightly attached to the outer wall of the annular post 25. However, due to the anti-stick coating on the outer wall of the annular post 25, the tape 103 will not stick to the outer wall of the annular post 25. Then, the lifting frame 1 is hooked onto the paper roller 101 by the hook of the lifting device through the round hole, and the lifting frame 1 is lifted to the top of the paper roller 101 by the lifting device. Then, the lifting frame 1 is lowered onto the paper roller 101 by the lifting device, so that the bottom end of the lifting frame 1 contacts the paper roller 101. Then, the servo motor II11 drives the gear II12 to rotate, so that the gear II12 drives the arc rack II13 to rotate, so that the arc rack II13 locks the paper roller 101 onto the lifting frame 1, thereby fixing the paper roller 101. Then, the electric slide rail 5 drives the cutter I6 and cutter II7 to move closer to the paper roll 102, so that cutter I6 is pressed against the paper roll 102 on the paper roller 101, and cutter II7 is pressed against cutter I6. Then, the servo motor I9 on the rear side drives the arc-shaped rack I3 on ​​the rear side to rotate counterclockwise, thereby driving the connecting frame 4 on the rear side and cutter I6 to rotate counterclockwise, so that cutter I6 rotates counterclockwise against the paper roll 102. During this process, the friction reduction wheel 8 rolls on the paper roll 102, which can reduce the friction between cutter I6 and paper roll 102. When cutter I6 rotates counterclockwise to contact the uneven part at the end of paper roll 102, cutter I6 will cut the uneven part at the end of paper roll 102. When the cutter I6 rotates counterclockwise to a point above the uneven end of the roll of paper 102, the servo motor I9 on the rear side drives the arc-shaped rack I3 on ​​the rear side to stop rotating counterclockwise. Then, the servo motor I9 on the front side drives the arc-shaped rack I3 on ​​the front side to rotate clockwise, thereby driving the connecting frame 4 and the cutter II7 on the front side to rotate clockwise. When the cutter II7 rotates clockwise to contact the cutter I6, the cutter II7 will cut off the uneven end of the roll of paper 102 that the cutter I6 has lifted. Then, the servo motor I9 on the front side drives the arc-shaped rack I3 on ​​the front side to stop rotating clockwise. In this way, the uneven end of the roll of paper 102 can be automatically cut off. Then, the electric push rod 15 drives the connecting frame 16, the fixed frame 19, the guide wheel 20, the movable frame 21, and the adhesive wheel 22 to move closer to the paper roll 102, so that the adhesive wheel 22 attaches one end of the tape 103 to the end of the paper roll 102. Then, the electric roller 24 drives the annular column 25 and the cutter III 26 to rotate counterclockwise, so that the counterclockwise rotating annular column 25 and the adhesive wheel 22 squeeze each other and drive the tape 103 to be discharged. At the same time, the servo motor I9 drives the arc rack I3 to rotate clockwise, thereby driving the connecting frame 4, the cutter I6 and the cutter II 7 to rotate clockwise synchronously, which in turn drives the connecting block 14, the electric push rod 15, the connecting frame 16, the fixed frame 19, the guide wheel 20, the movable frame 21, and the adhesive wheel 22 to rotate clockwise. The adhesive roller 22 rotates clockwise, causing it to apply the discharged adhesive tape 103 clockwise from the end of the roll of paper 102. After the adhesive roller 22 rotates clockwise past the end of the roll of paper 102, it will continue to apply the discharged adhesive tape 103 clockwise over the end of the roll of paper 102. When the adhesive tape 103 between the annular column 25 and the adhesive roller 22 comes into contact with the counter-clockwise rotating cutter III 26, the cutter III 26 will cut the adhesive tape 103 between the annular column 25 and the adhesive roller 22, separating the adhesive tape 103 on the roll of paper 102 from the adhesive tape 103 on the feeding rod 17. This allows the adhesive roller 22 to apply the cut portion of the adhesive tape 103 entirely onto the roll of paper 102. Simultaneously, the counter-clockwise rotating annular column 25... The conveyor belt 103 on the feeding rod 17 will continue to discharge, allowing it to pass between the adhesive roller 22 and the annular column 25. The adhesive roller 22 will then re-attach the first end of the tape 103 for future use. After the adhesive roller 22 has applied the entire cut portion of tape 103 to the roll paper 102, the other end of the cut portion will be finally attached to the roll paper 102, securing the tail end of the roll paper 102. Then, the electric roller 24 will be controlled to stop the annular column 25 and the cutter Ⅲ 26 from rotating counter-clockwise, while the servo motor Ⅰ9 will be controlled to stop the arc-shaped rack Ⅰ3 from rotating clockwise. Then... The electric push rod 15 drives the connecting frame 16, the fixed frame 19, the guide wheel 20, the movable frame 21, and the pasting wheel 22 to move and reset to the side away from the roll paper 102. Then, the electric slide rail 5 drives the cutter I6 and cutter II7 to move and reset to the side away from the roll paper 102, so that the cutter I6 separates from the roll paper 102 on the paper roller 101. After that, the servo motor I9 drives the arc rack I3 to rotate counterclockwise to reset, thereby driving the connecting frame 4, cutter I6, and cutter II7 to rotate counterclockwise synchronously to reset. This, in turn, drives the connecting block 14, the electric push rod 15, the connecting frame 16, the fixed frame 19, the guide wheel 20, the movable frame 21, and the pasting wheel 22 to rotate counterclockwise to reset. In this way, the tail end of the roll paper 102 can be automatically fixed. Then, the lifting device is used to lift and move the lifting frame 1 and the paper roller 101 until the lifting device lifts the lifting frame 1 and the paper roller 101 in the designated position. Then, the servo motor II11 drives the gear II12 to reverse and reset, so that the gear II12 drives the arc rack II13 to reverse and reset, thereby releasing the paper roller 101 on the lifting frame 1.

[0035] See Figure 11 As shown, it also includes a positioning mechanism, which includes a laser sensing component 27, a sensing block 28, and a Hall effect sensing component 29. The laser sensing component 27 is connected to the cutter I6 and consists of a laser sensor and a control module I. The laser sensor is electrically connected to the control module I, and the control module I is electrically connected to the two servo motors I9 on the rear side. By using the laser sensor to sense the tail end of the paper roll 102, when the laser light from the laser sensor is completely blocked by the tail end of the paper roll 102, the laser sensor will send a signal to the control module I. After receiving the signal, the control module I will control the two servo motors I9 on the rear side to stop the cutter I6 from rotating, thereby positioning the end position of the cutter I6 on the paper roll 102. The sensing block 28 is installed on the cutter I6 so that the sensing block 28 can rotate synchronously with the cutter I6; the Hall sensor assembly 29 is installed on the upper right side of the front connecting frame 4, and the Hall sensor assembly 29 consists of Hall sensor I and control module II. Hall sensor I is electrically connected to control module II, and control module II is electrically connected to the two front servo motors I9. When Hall sensor I in the Hall sensor assembly 29 rotates with the front connecting frame 4 to align with the sensing block 28, Hall sensor I can sense the sensing block 28 and send a signal to control module II. After receiving the signal, control module II controls the two front servo motors I9 to drive the cutter II7 to stop rotating, thereby positioning the end position of the cutter II7 on the paper roll 102.

[0036] When the cutter I6 and the rear connecting frame 4 rotate counterclockwise, the cutter I6 will drive the laser sensing component 27 and the sensing block 28 to rotate counterclockwise synchronously. When the cutter I6 scrapes up the uneven part at the end of the paper roll 102, the uneven part at the end of the paper roll 102 will gradually block the laser sensing component 27, thereby blocking the laser light from the laser sensor. When the laser light from the laser sensor is completely blocked, it indicates that the position of the cutter I6 in counterclockwise rotation is higher than the uneven part at the end of the paper roll 102. At this time, the laser sensor will send a signal to the control module I, so that the control module I receives the signal and controls the two servo motors I9 at the rear to drive the cutter I6 to stop rotating counterclockwise. The cutter I6 automatically positions itself at the end of its rotation on the paper roll 102 to assist users. When the connecting frame 4 and cutter II7 rotate clockwise, the connecting frame 4 drives the Hall sensor assembly 29 to rotate clockwise synchronously. When the Hall sensor I inside the Hall sensor assembly 29 rotates clockwise to align with the sensing block 28, the Hall sensor I senses the sensing block 28 and sends a signal to the control module II. After receiving the signal, the control module II controls the two servo motors I9 on the front to stop the clockwise rotation of the connecting frame 4 and cutter II7, thereby positioning the end of the cutter II7's rotation on the paper roll 102 to assist users.
