Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of toilet paper production, in particular to a toilet paper production equipment. BACKGROUND

[0002] The production of toilet paper roll includes papermaking, winding, cutting and packaging. In a large production line, the cutting and packaging of toilet paper roll are continuously and automatically carried out through a flow line. The long toilet paper roll is divided into several sections of appropriate length by a band saw paper cutting machine, and then a certain number of cut toilet paper rolls are packaged together. Finally, they are transported, sold or stored. This production method has high automation degree, and only relies on manpower in the final transportation step, which has low labor cost. However, the full-automatic cutting and packaging involves many devices and a large area of site, and the production cost is high in the early stage. For small toilet paper manufacturers, only a paper cutting machine is provided, and the cut toilet paper is packaged by manpower. The packaging process includes stacking, bagging and carrying. If only one person is responsible for these two processes, the paper cutting machine needs to be appropriately reduced in cutting speed. Therefore, multiple workers are generally arranged at the discharge port of the paper cutting machine to meet the production needs of the paper cutting machine. Although the production cost is low in the early stage, the labor cost is high in the long-term production, which is not conducive to the development of enterprises.

[0003] Therefore, the present application provides a toilet paper production equipment. After the positioning and correction of the toilet paper roll falling on the support plate by the side plate, the stacked toilet paper roll is smoothly and accurately dropped into the carton by the electric push rod and the clamping plate. Only one worker can meet the normal production speed of the paper cutting machine to solve the problem of high labor cost in packaging the toilet paper roll.

[0004] The above information disclosed in the background section of this document is only intended to enhance the understanding of the background of the present disclosure, and therefore can contain information known to those skilled in the art prior to the present disclosure. SUMMARY

[0005] The present application aims to provide a toilet paper production equipment. After the positioning and correction of the toilet paper roll falling on the support plate by the side plate, the stacked toilet paper roll is smoothly and accurately dropped into the carton by the electric push rod and the clamping plate. Only one worker can meet the normal production speed of the paper cutting machine to solve the problem raised in the above background.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical scheme:

[0007] A toilet paper production equipment comprises a paper cutting machine, a conveyor belt and a workbench. A transmission belt is arranged at the discharge port of the paper cutting machine, and the workbench is placed at the discharge port of the transmission belt.

[0008] A stacking device is arranged on the workbench, and is used to automatically stack the cut toilet paper roll.

[0009] The slope conical plate is arranged at the discharge port of the paper cutter, the cut paper roll falls on the conveying belt through the conical plate, and then the paper roll falls on the stacking device through the transmission belt in sequence, the worker only needs to place the paper box on the workbench, and the stacking device is used to automatically stack and bag the paper roll, and the paper roll is filled into the paper box, and then the paper box is taken out when the paper box is filled with enough paper roll, during the stacking device fills the paper roll into the paper box, the worker moves the packaged paper roll to the outside of the workbench, reduces the operation steps of the worker, and only one person can meet the production speed of the paper cutter, reduces the labor cost, and reduces the labor intensity of the worker.

[0010] Preferably, the stacking device comprises a plurality of support rods fixedly installed on the workbench, a plurality of support rods are fixedly installed on the support plate, a positioning ring is movably installed on the support plate, positioning blocks are fixedly installed on both sides of the positioning ring, the positioning ring and the positioning block are connected through a spring, a through groove matched with the positioning ring is formed in the support plate, a guide cylinder is fixedly installed in the through groove, a lifting assembly and a clamping mechanism are arranged on the support plate, a storage device is arranged on the workbench, the storage device is used to contain the stacked paper roll, and a gravity sensor is arranged in the positioning ring.

[0011] Preferably, the clamping mechanism comprises an electric push rod fixedly installed at the bottom of the support plate, a fixed block is fixedly installed at the movable end of the electric push rod, two fixed rods are fixedly installed at both ends of the fixed block, a clamping plate is installed on each of the two fixed rods through a torsion spring, a clamping plate is fixedly installed on the support plate, and an inclined slot matched with the clamping plate is formed in the clamping plate.

[0012] Preferably, the storage device comprises a motor fixedly installed on the workbench, and a rotating disc is rotatably installed in the workbench and connected with the motor through a synchronous belt.

[0013] The height of the discharge port of the transmission belt is slightly higher than the position where the support plate is located, and the paper roll can directly fall on the positioning ring from the conveying belt. The gravity sensor is electrically connected with the electric push rod, the electric push rod is electrically connected with the motor, the extension function of the electric push rod is controlled by the motor, the gravity sensor controls the retraction of the electric push rod, and after the electric push rod completes the retraction action, the electric push rod controls the motor to rotate by 90 degrees, and the motor is a servo motor.

[0014] Four areas for containing the paper roll are arranged on the rotating disc, the paper box is placed on the rotating disc, the stacked paper roll falls into the square paper box after stacking, and four vertically stacked paper rolls can maximize the filling of the paper box.

[0015] Specifically, the carton is first placed on the turntable, the angle of each rotation of the motor is set to 90°, the gravity sensor starts to work only when the electric push rod is extended, and the gravity sensor will be closed once the electric push rod makes a retreat action. The first rotation of the turntable is manually controlled, and the operation servo motor rotates 90°. The servo motor controls the electric push rod to extend once every 90°. At this time, the fixed block drives the clamping plate to move upward in the inclined groove of the clamping plate. During this period, the two clamping plates gradually close and clamp the paper roll under the action of the inclined groove, until the electric push rod completes the extension action and remains in the extended state. At this time, the gravity sensor in the positioning ring starts to work, waiting for the next paper roll to fall on the positioning ring. The retreat action of the electric push rod is controlled by the gravity sensor. Each time the paper roll falls on the positioning ring, the gravity sensor will be triggered and control the electric push rod to retreat to the initial position, and the clamped paper roll is stacked on the paper roll in the positioning ring. During the stacking process, since the positioning ring is split, the positioning ring is pressed and moves to both sides. The diameter of the through groove is larger than the diameter of the positioning ring, and the two paper rolls on the positioning ring will fall together along the guide cylinder into the carton on the turntable. At this time, the electric push rod completes the retreat action, and controls the motor to rotate 90°, so that the subsequent paper roll falls in the next containing area, and the subsequent paper roll repeats the above action.

[0016] It is worth noting that the two paper rolls falling together can effectively prevent the paper roll from bouncing when it falls on the carton. The reason is that when the bottom paper roll bounces when it contacts the carton, it will be pressed down by the top paper roll and consume part of the potential energy of the top paper roll when it falls. When the top paper roll falls on the bottom paper roll, due to the low hardness of the paper roll, the potential energy of the falling is offset by the deformation of the paper roll, further reducing the bounce amplitude of the top paper roll, so that the paper roll falls smoothly into the carton. And the interval between the support plate and the workbench can be appropriately shortened, so that the top of the carton is flush with the top of the guide cylinder, reducing the falling height of the paper roll and improving the stability, or the electric push rod can be set on the top of the support plate, which can further reduce the interval between the support plate and the workbench.

[0017] The distance of each extension of the electric push rod is between one and two paper roll lengths, which can be adjusted by the user according to the length of the paper roll cut by the paper cutting machine. In order to facilitate the worker to handle other matters during the stacking of the paper roll, such as carrying the full carton, a gravity sensing device is arranged in the turntable, which prompts the worker to replace the carton when the weight of the paper roll in the carton reaches the preset value.

[0018] According to the height of the carton, the height of the paper roll required to be stacked is different, the electric push rod can be arranged on the top of the support plate, and the height of the guide cylinder and the workbench can be appropriately adjusted, so that the worker can place the carton on the turntable, and the production efficiency is improved.

[0019] Since the width of the conveying belt is larger than the area of the positioning ring, a guide plate is arranged at the discharging opening of the conveying belt to fix the falling point of the paper roll on the conveying belt in the positioning ring.

[0020] Further, a plurality of correction blocks are fixedly installed on the rotating disc.

[0021] The middle part of the correction block has a notch, and the four corners of the carton can be embedded in the correction block, so that the worker can correctly place the carton on the rotating disc.

[0022] In addition, as an embodiment of the present application, since the clamping force of the clamping plate on the paper roll is gradually increased, when the paper roll with high gravity is clamped, in the early stage of clamping, the paper roll is easy to rotate due to insufficient clamping force, so the way of tightening the clamping plate by the chute alone is unstable. If the taper of the chute is increased greatly, when the electric push rod is extended, the clamping plate rapidly rotates at a large angle in the chute, but when the clamping plate rises, the vertical component force of the clamping plate increases, and the clamping plate is easy to warp during clamping, and the connection between the clamping plate and the fixed rod will loosen after a long time, reducing the service life.

[0023] Therefore, the positioning rod is replaced by a motor, and the clamping plate is fixedly installed on the output end of the motor.

[0024] The electric push rod is electrically connected with the motor, and the motor is started when the electric push rod is extended, and the motor is stopped when the electric push rod is retracted. The clamping plate can be opened and closed under the control of the motor, and when the output end of the electric push rod is located at the initial position, the two clamping plates are in an open state; when the electric push rod is extended, the motor rotates by a set angle to clamp the paper roll in the positioning ring by the two clamping plates. When the electric push rod is retracted to the initial position, the motor rotates back to the initial position, and the two clamping plates are opened to release the paper roll.

[0025] The motor is used to control the clamping plate, and a large clamping force can be obtained when the clamping plate contacts the paper roll. When the paper roll is thick or has a compact structure, the paper roll is not easy to deflect during clamping, and the stacked paper rolls are more uniform, so that the paper roll falls more stably in the carton. The diameter range that can be clamped by the clamping plate can be controlled by controlling the rotation angle of the motor, and more diameter ranges of the paper roll can be adapted. However, the motor is expensive, and an additional electric control system is also required to control the start and stop of the motor.

[0026] Further, a rubber pad is installed on the clamping plate.

[0027] Further, the rubber pad is arc-shaped.

[0028] The rubber pad contacts the paper roll to increase the friction force when the clamping plate clamps the paper roll, preventing the paper roll from rotating in the lifting process, and making the paper roll more stable in the lifting process.

[0029] The rubber pad is arc-shaped, increasing the contact area with the side wall of the paper roll, further preventing the paper roll from rotating, and since the radius of the rubber pad is smaller than the radius of the paper roll, the rubber pad is stretched and wrapped around the side wall of the paper roll when the clamping plate is closed, to adapt to paper rolls of different diameters.

[0030] The two clamping plates close to clamp the paper roll when the electric push rod is extended, and the clamping force is sufficient to lift the paper roll at this time. The clamping force increases continuously during the lifting process of the electric push rod, and the clamping force of the clamping plate on the paper roll is the largest when the extension stroke of the electric push rod ends. However, since the rubber pad increases the contact area with the paper roll, the integrity of the side wall of the paper roll is ensured, and since the material of the rubber pad is relatively soft, it can be deformed to offset when the clamping force is too large. Alternatively, the taper of the inclined groove in the clamping plate can be appropriately adjusted to reduce the closing amount of the clamping plate during the lifting process and reduce the clamping force.

[0031] Preferably, two positioning rods are symmetrically and fixedly installed on the support plate, and a side plate is rotatably installed on each of the two positioning rods.

[0032] The side plate and the clamping plate are in the same vertical plane. When the rotating disc aligns the containing area with the guide cylinder, the electric push rod is extended and remains stationary. However, since the extension length of the electric push rod is greater than the thickness of the paper roll, the blocking of the paper roll falling from the conveyor belt is insufficient, and the paper roll is easily bounced out of the positioning ring when it falls on the support plate.

[0033] Therefore, two side plates are provided on the support plate to correct the paper roll falling on the positioning ring and prevent the paper roll from deviating too much from the predetermined area when it falls.

[0034] It is worth noting that since the guide plate is provided on the transmission belt, the direction and kinetic energy of the paper roll when it leaves the conveyor belt are fixed. As long as the distance between the transmission belt and the positioning ring is reasonably set, the paper roll can be accurately dropped onto the positioning ring.

[0035] Preferably, a crossbar is fixedly installed on the output end of the electric push rod, a wedge-shaped block that cooperates with the side plate is fixedly installed on the crossbar, and a torsional spring is fixedly installed between the side plate and the positioning rod.

[0036] Further, a ball bearing is rotatably installed on the side wall.

[0037] The wedge moves along with the electric push rod, when the paper roll falls on the positioning ring, the electric push rod moves to the initial position, driving the wedge to press the side plates to the end of the fixed block, so that the two side plates are closed to overcome the force of the torsion spring, correcting the position of the paper roll on the positioning ring, and fixing the paper roll. When the clamping plate moves downward, the paper roll clamped by the clamping plate can be accurately placed on the paper roll at the positioning ring, and when the paper roll is carried upward by the clamping plate, the ball reduces the axial friction of the side plate on the paper roll, so that the clamping plate easily takes away the paper roll, at this time, the wedge moves upward along with the electric push rod, and the side plate returns to the open state, preventing the paper roll from falling off.

[0038] Preferably, a sliding rod is fixedly installed on the side wall of the clamping plate close to the rubber pad, and the sliding rod slides in the clamping plate.

[0039] The clamping plate releases the paper roll after the electric push rod returns to the initial position, however, since the clamping position of the clamping plate on the paper roll is located in the middle, when the paper roll is stacked on another paper roll, it still needs to move a distance, and if the rubber pad is fixedly installed on the clamping plate, it is not convenient to stack the paper roll. Therefore, the rubber pad is arranged to be slidingly installed on the clamping plate, the sizes of the two ends of the sliding rod are larger, preventing the rubber pad from completely separating from the clamping plate, so when the clamping plate starts to stack the paper roll, the rubber pad is still clamped in the middle of the paper roll, and the clamping plate continues to move downward until the electric push rod is reset, and after the clamping force of the clamping plate on the paper roll is lost, the rubber pad falls on the clamping plate again.

[0040] Since the pressure of the clamping plate on the paper roll on the supporting plate is reduced during the stacking process, the spring force of the positioning ring can be reduced at this time, since the cross section of the positioning ring is trapezoidal, the gravity of the two paper rolls is used to move the positioning ring to both sides, so that the paper roll falls from the through groove.

[0041] It should be noted that the main effect of the positioning ring on the paper roll is support, and during the falling process of the paper roll from the positioning ring, the positioning ring clamps the side wall of the paper roll, but this does not hinder the falling of the paper roll, and the influence on the falling of the paper roll can be further reduced by rounding the inner ring of the positioning ring or polishing.

[0042] Compared with the prior art, the beneficial effects of the present application are:

[0043] 1. A material feeding device is arranged at the discharge port of the transmission belt, and the clamping plate is driven upward by an electric push rod. During the movement of the clamping plate in the inclined groove in the clamping plate, the clamping plate is continuously clamped inward, the paper roll falling on the positioning ring is lifted, and the next paper roll falling on the positioning ring is clamped, and the clamped paper roll is stacked on the paper roll in the positioning ring. Since the positioning ring is split, the springs on both sides cannot bear the weight of the two paper rolls, the positioning ring moves to both sides, the diameter of the through groove is larger than the diameter of the positioning ring, and the paper roll falls along the guide cylinder and falls into the carton on the rotating disc. The rotating disc rotates the carton, so that the paper roll is positioned and quantitatively dropped at the four corners of the carton, and finally the carton is filled. A worker can meet the normal production speed of the paper cutting machine and save labor cost.

[0044] 2. The paper rolls fall into the carton two by two, and the bottom paper roll is pressed down by the top paper roll when it contacts the carton and bounces, and consumes part of the potential energy of the top paper roll when it falls. When the top paper roll falls on the bottom paper roll, the potential energy of the falling is offset by the deformation of the paper roll, further reducing the bouncing amplitude of the top paper roll, so that the paper roll falls smoothly into the carton, ensuring that the subsequent paper roll can be smoothly filled into the carton.

[0045] 3. The rubber pad is arranged to be slidingly installed on the clamping plate, and the sizes of the two ends of the sliding rod are larger to prevent the rubber pad from completely separating from the clamping plate. When the clamping plate starts to stack the paper roll, the rubber pad is still clamped in the middle of the paper roll, and the clamping plate continues to move downward until the electric push rod resets. After the clamping plate loses the clamping force on the paper roll, the rubber pad falls on the clamping plate again to prevent the paper roll from being abraded by friction with the clamping plate during stacking.

DETAILED DESCRIPTION

[0054] Aspects and features of the present disclosure, as well as methods of implementing them, will be apparent from the detailed description, however, the disclosure is not limited to the embodiments disclosed below and can be implemented in various forms. The present embodiments are provided to help those of ordinary skill in the art to fully understand the present disclosure, and the present disclosure is limited only within the scope of the appended claims.

[0055] Embodiment one, when the diameter of the packaged paper roll is less than 30mm and the thickness is 100mm, please refer to Figures 1 to 7 The present application provides a sanitary paper production equipment, and the technical scheme is as follows:

[0056] The drive belt discharge port is arranged 5mm above the support plate 1, a guide plate is arranged at the discharge port of the drive belt, and the falling point of the paper roll falling on the drive belt is fixed in the positioning ring 209. The gravity sensor is electrically connected with the electric push rod 2, the electric push rod 2 is electrically connected with the motor 301, the extension function of the electric push rod 2 is controlled by the motor 301, the gravity sensor controls the retraction function of the electric push rod 2, after the electric push rod 2 completes the retraction action, the electric push rod 2 controls the motor 301 to rotate, the motor 301 is a servo motor 301, and the servo motor 301 rotates 90° each time.

[0057] In order to conveniently take the carton off the turntable 302, the correction block 303 can be arranged only three, and the placement and taking of the carton are both from the direction where the correction block 303 is arranged.

[0058] Before starting the motor 301, the bottom corner of the carton is placed on the correction block 303 on the turntable 302, and the gravity sensor will be turned off as soon as the electric push rod 2 makes a retraction action.

[0059] The capacity of the carton is 16 rolls of paper, if the production of the previous day is not a multiple of 16, there will be remaining rolls of paper in the carton that are not sealed, the remaining rolls of paper in the carton are placed on the positioning ring 209 before starting production, or the production of the previous day is a multiple of 16, the rolls of paper need to be manually taken from the conveyor belt and placed on the positioning ring 209, after the first roll of paper is placed on the positioning ring 209, the motor 301 is controlled to rotate 90°, at this time the electric push rod 2 is extended, during which the two clamping plates 203 are gradually closed and clamp the middle part of the roll of paper under the action of the inclined groove 2011, and move upward by 20 cm along with the fixed block 206, at this time the roll of paper on the clamping plate 203 is 15 cm away from the transmission belt, preventing interference with the roll of paper falling on the positioning ring 209.

[0060] The clamping plate 203 is fixedly installed with a rubber pad 204, which is arc-shaped, when the clamping plate 203 contacts the roll of paper, the contact area with the side wall of the roll of paper is increased, preventing the roll of paper from deviating during the process of following the electric push rod 2 upward, and because the radius of the rubber pad 204 is smaller than the radius of the roll of paper, when the clamping plate 203 clamps the roll of paper, the rubber pad 204 is stretched and wrapped on the side wall of the roll of paper, further ensuring that the roll of paper follows the clamping plate 203 upward in a horizontal posture, the electric push rod 2 moves upward by 20 cm and stops, and remains in an extended state, at this time the gravity sensor in the positioning ring 209 is activated.

[0061] When the second roll of paper falls on the positioning ring 209, the gravity sensor is triggered, the electric push rod 2 is controlled to descend, during which the wedge-shaped block 202 extrudes the side plate 207 close to one end of the fixed block 206, so that the two side plates 207 overcome the force of the torsional spring and close, correcting the position of the roll of paper just falling on the positioning ring 209, the closing diameter of the side plate 207 is equal to the diameter of the positioning ring 209, and the side wall of the side plate 207 is very smooth, if the roll of paper does not fall into the positioning ring 209, it will be extruded into the positioning ring 209 by the side plate 207, the cross section of the positioning ring 209 is trapezoidal, after the roll of paper enters the positioning ring 209, the side plate 207 cannot move through the clamping pressure to move the roll of paper, achieving position correction of the roll of paper.

[0062] At this time the electric push rod 2 has descended by 10 cm, the roll of paper on the clamping plate 203 has descended above the roll of paper in the positioning ring 209, and the clamped roll of paper is stacked on the roll of paper in the positioning ring 209, the rubber pad 204 is installed on the clamping plate 203 through a sliding rod 2041, the thickness of the rubber pad 204 is 5 cm and the length of the sliding rod 2041 is 15 cm, during the stacking process, the rubber pad 204 is still clamped in the middle of the roll of paper, and the clamping plate 203 still moves downward by 10 cm, until the electric push rod 2 is reset, and the clamping plate 203 ends the clamping state, when the clamping plate 203 loses the clamping force on the roll of paper, the rubber pad 204 falls back on the clamping plate 203.

[0063] When two paper rolls are placed on the positioning ring 209, the positioning ring 209 is pressed to the two sides by the gravity of the two paper rolls, and the two paper rolls on the positioning ring 209 will fall into the carton on the rotating disc 302 along the guide cylinder 213, at this time, the electric push rod 2 completes the return action, and the motor 301 drives the rotating disc 302 to rotate by 90°, and after the rotating disc 302 rotates by 90° each time, two paper rolls will fall into the carton, and the carton can accommodate 16 paper rolls, when the rotating disc 302 rotates by one circle, the falling paper rolls first fill the bottom of the carton, and after the rotating disc 302 rotates by one circle, the carton is filled. A gravity sensing device is arranged in the rotating disc 302, and when the weight of the paper rolls in the carton reaches a preset value, a worker is prompted to replace the carton. During the period when the electric push rod 2 clamps the paper rolls, the worker takes the carton from the rotating disc 302 and replaces the empty carton, and during the period when the paper rolls fill the carton, the worker can use the idle time to transfer or bundle the filled carton.

[0064] In the second embodiment, when the produced toilet paper is relatively thick and the diameter of the paper roll is greater than 30 mm and the thickness is 100 mm, the weight is obviously increased compared with the first embodiment. Since the clamping force of the clamping plate 203 on the paper roll is gradually increased, when the clamping gravity of the paper roll is high, the paper roll is prone to rotate in the early stage of clamping, and therefore the way of tightening the clamping plate 203 by the inclined groove 2011 to clamp the paper roll is unstable. If the taper of the inclined groove 2011 is greatly increased, the clamping plate 203 rapidly rotates by a large angle in the inclined groove 2011 when the electric push rod extends, but when the taper of the inclined groove 2011 is too large, the vertical component force on the clamping plate 203 increases when the clamping plate 203 rises, and the clamping plate 203 is prone to warp when clamping, and the connection between the clamping plate 203 and the fixed rod 205 will be loose after a long time, and the service life is reduced.

[0065] In an embodiment of the present application, the positioning rod 208 is replaced by a motor, and the clamping plate 203 is fixedly installed on the output end of the motor.

[0066] The electric push rod 2 is electrically connected with the motor, the motor is started when the electric push rod 2 extends, and the motor stops rotating when the electric push rod 2 retracts. The clamping plate 203 can be opened and closed under the control of the motor, and when the output end of the electric push rod 2 is located at the initial position, the two clamping plates 203 are in the opened state; when the electric push rod 2 extends, the motor rotates by a set angle to clamp the paper roll in the positioning ring 209 by the two clamping plates 203. When the electric push rod 2 retracts to the initial position, the motor rotates back to the initial position, and the two clamping plates 203 are opened to put down the paper roll.

[0067] The motor controls the clamping plate 203, and a larger clamping force can be obtained when the clamping plate 203 contacts the paper roll. When clamping a single sheet of thick or compact structure toilet paper, deflection is not easy to occur during the clamping process, and the stacked paper roll is more neat, so that the paper roll falls more stably in the carton. The diameter range that the clamping plate 203 can clamp is controlled by controlling the rotation angle of the motor, and more diameter ranges of the paper roll can be adapted. However, the price of the motor is relatively high, and an additional electric control system is also required to start and stop the motor.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate and facilitate the understanding of the technical solutions of the present application, and are not limited thereto; the technical solutions described in the above embodiments can still be modified, or some technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the inventive concept of the present application.
