Description

Technical Field

[0001] The present application belongs to the technical field of tissue paper production and processing, and in particular relates to a tissue paper stacking device. Background Art

[0002] The primary function of a tissue stacking device is to stack folded tissue products in a specific quantity and sequence for subsequent packaging and transportation. This device typically uses a robotic arm or conveyor belt to remove folded tissue products from the production line and stack them in a predetermined order and quantity. It is primarily used at the end of a tissue production line, where the stacked tissues require additional equipment for receiving and transporting.

[0003] The publication number is a transfer device for tissue paper production, including a transfer box and a bottom plate on its bottom side, two sets of cylinder seats in opposite positions are fixedly installed on the top of the bottom plate, and the top ends of the two sets of cylinder seats are equipped with a top plate located on the inner side of the transfer box; a feed trough is opened on the top of the left side of the transfer box.

[0004] The above patent can structure stacked tissue paper and stack it for transportation. Although it can be tilted so that the stacked tissue paper can be discharged from the discharge chute, the weight of the tissue paper is relatively light and cannot automatically slide down by relying on the tilt angle and gravity, which easily leads to some tissue paper remaining on the top plate, and needs to be improved. Summary of the Invention

[0005] The purpose of this application is to provide a paper pulling and stacking device that can solve the above problems.

[0006] The purpose of this application is to provide a paper stacking device, including a stacking mechanism, and further comprising:

[0007] A conveyor belt is provided on one side of the stacking device for conveying tissue paper;

[0008] The transfer mechanism is provided on the side of the conveyor belt away from the stacking device, and is used to receive the paper sheets and transport the stacked paper sheets after they are stacked. The transfer device includes:

[0009] A receiving structure for receiving paper;

[0010] The pushing structure is arranged on the receiving structure and is used to assist in the extraction of the stacked paper.

[0011] The above-mentioned paper stacking device is used to achieve continuous and stable input of paper by providing a conveyor belt, providing a reliable foundation for subsequent stacking operations. The combined use of the receiving structure and the pushing structure ensures that the stacked paper can be smoothly and efficiently exported, avoiding the problem of residual paper caused by the difficulty of paper sliding off. The setting of the pushing structure also effectively assists the stacked paper to slide off the receiving structure, reducing the residual phenomenon caused by the light weight of the paper. Not only does it improve the stacking efficiency of the paper, but it also reduces the waste of paper caused by residual paper, thereby improving the overall economic benefits.

[0012] Furthermore, the receiving structure includes:

[0013] The frame has a receiving port on its top and a receiving plate on one side of the receiving port;

[0014] A lifting plate, a first cylinder and a second cylinder are spaced apart at the bottom thereof;

[0015] The material guide port is arranged on the side wall of the frame body, and a blocking plate is provided on the material guide port;

[0016] The output shafts of the first cylinder and the second cylinder are hinged to the lifting plate.

[0017] The frame serves as the main part of the receiving structure, with a receiving port at the top for receiving the paper sheets from the conveyor belt. A receiving plate is located on one side of the receiving port, providing support and guidance during the stacking process. A lifting plate is located within the frame, supporting the stacked paper sheets. A first cylinder and a second cylinder are spaced apart at the bottom of the lifting plate as the power sources for lifting and adjusting the height and tilt angle of the lifting plate. A material guide port is located on the side wall of the frame, serving as a channel for the stacked paper sheets. A blocking plate is provided on the material guide port to keep the port closed during the stacking process, preventing the paper sheets from slipping off prematurely.

[0018] When the conveyor belt transports the tissue paper to the receiving port, the receiving plate plays a supporting role, allowing the tissue paper to fall smoothly onto the lifting plate. As the tissue paper is stacked, the first cylinder and the second cylinder keep the lifting plate in a horizontal state to ensure the stability and neatness of the stacking process. When the stacking is completed, the lifting plate is tilted by adjusting the output shaft lengths of the first cylinder and the second cylinder. Due to the hinged design of the two cylinders, the lifting plate can be tilted at a certain angle, so that the stacked tissue paper slides toward the guide port under the action of gravity. Before the tissue paper is about to be discharged from the guide port, the sealing plate is opened to keep the guide port open, allowing the tissue paper to slide smoothly. The setting of this receiving structure realizes the smooth reception and stacking of tissue paper, and at the same time, the lifting and tilting functions of the cylinder are utilized to enable the stacked tissue paper to be smoothly discharged from the guide port.

[0019] Further: the push structure includes:

[0020] A push plate, arranged on one side of the lifting plate;

[0021] The driver is arranged at the bottom of the lifting plate, and its output shaft is connected to the push plate;

[0022] A slide groove is provided on the lifting plate and is used for the push plate to slide;

[0023] Among them, a connecting rod adapted to the sliding groove is provided at the bottom of the push plate, and the connecting rod is connected to the output shaft of the driver.

[0024] A push plate is provided on one side of the lifting plate and is used to push the stacked paper sheets after stacking is completed. The push plate has a certain degree of rigidity and wear resistance to ensure that the paper sheets are not damaged during the pushing process. A driver is provided at the bottom of the lifting plate and serves as the power source for the pushing structure. Its output shaft is connected to the push plate, and the reciprocating motion of the push plate is achieved through the operation of the driver. A chute is provided on the lifting plate for the push plate to slide. A connecting rod is provided at the bottom of the push plate and is adapted to the chute. One end of the connecting rod is connected to the push plate, and the other end is connected to the output shaft of the driver. The power output of the driver is achieved to the push plate through the transmission action of the connecting rod.

[0025] When the stack of paper sheets is completed on the lifting plate, the driver starts to operate, and the driver's output shaft drives the push plate to slide in the chute through the connecting rod. During the sliding process, the push plate gradually approaches the stack of paper sheets until it contacts the paper sheets. At this time, the driver continues to operate, and the push plate, driven by the connecting rod, pushes the stack of paper sheets toward the feed outlet. As the push plate continues to push, the stack of paper sheets gradually slides down the feed outlet under the action of gravity and the push plate. During the sliding process of the paper sheets, the sealing plate should remain open to ensure that the paper sheets can be smoothly discharged. When the stack of paper sheets is completely discharged from the feed outlet, the driver stops operating, and the push plate, driven by the connecting rod, returns to its original position, awaiting the next stacking and pushing operation.

[0026] The automatic pushing of the drawn paper after stacking is realized, which improves the transfer efficiency and automation level of the stacking device, can effectively avoid the problem of drawn paper remaining on the lifting plate, and also improves the transfer efficiency.

[0027] Furthermore, the push structure also includes:

[0028] A damper is provided at the bottom of the lifting plate and located on one side of the driver, and the telescopic end of the damper is connected to the connecting rod;

[0029] A spring, disposed at the bottom of the lifting plate and connected to the connecting rod;

[0030] The spring sleeve is set outside the damper. The cooperation of the spring and the damper can make the movement of the push plate more stable, so that the pushing work is more urgent and stable, and the paper extraction startup protection is played.

[0031] The damper is located at the bottom of the lift plate, on one side of the actuator. Its telescopic end is connected to the connecting rod, providing appropriate resistance during the movement of the push plate, ensuring smoother movement and preventing shock and vibration caused by sudden acceleration or deceleration. A spring is located at the bottom of the lift plate, connected to the connecting rod, and sleeved onto the damper. This elastic support provides the push plate with a certain cushioning capacity during movement, absorbing and dissipating the impact force from the stacked paper sheets or the actuator's operation. When the actuator activates and drives the connecting rod, the push plate begins to push the stacked paper sheets. At this point, the damper activates, providing appropriate resistance to control the push plate's movement speed, preventing it from moving too fast or too slowly. Simultaneously, the spring activates, providing elastic support for the push plate, ensuring smooth paper pushing. If resistance or uneven distribution of the stacked paper sheets are encountered during the pushing process, the spring absorbs some of the impact force, protecting the push plate and the stacked paper sheets from damage. The damper maintains the stability of the push plate's movement, preventing excessive vibration and noise.

[0032] The coordinated action of the spring and damper ensures smoother and more controlled movement of the push plate, avoiding the shock and vibration caused by sudden acceleration or deceleration in traditional push mechanisms, thereby improving the stability and reliability of the push operation. The spring's elastic support absorbs and disperses the impact of stacked paper sheets and the driver's operation, protecting the stacked paper from damage. Furthermore, the damper's resistance control prevents the push plate from exerting excessive pressure or friction on the stacked paper, maintaining the integrity and quality of the paper.

[0033] Furthermore, a driving motor connected to the blocking plate is provided on the side wall of the frame, and the blocking plate can be controlled to open and close by the driving motor.

[0034] The drive motor is mounted on the side wall of the frame and connected to the sealing plate via a rotating shaft. When the stack of paper needs to be discharged, the control system sends an open signal to the drive motor. Upon receiving this signal, the drive motor begins to operate, driving the sealing plate to the side via a transmission mechanism, thereby opening the paper guide port. When all paper has been discharged, the control system sends a close signal to the drive motor, causing it to operate again, and the transmission mechanism pulls the sealing plate back into position, closing the paper guide port.

[0035] The use of a drive motor realizes the control of the opening and closing action of the blocking plate, ensuring that the stacked paper can be discharged at the correct time and position, avoiding the problem of paper residue or scattering caused by inaccurate blocking plate action.

[0036] Furthermore, the bottom of the frame is provided with universal wheels, a plurality of universal wheels are provided, and the side walls of the frame are also provided with push handles.

[0037] Multiple universal wheels at the bottom of the frame provide the device with all-around mobility. Push handles on the side walls provide convenient grips for operators, allowing them to easily push or pull the device for movement. When the device needs to be moved, the operator can control its direction and speed by gripping the push handles, preventing accidents such as collisions and falls.

[0038] The beneficial effects of this application are:

[0039] 1. The push structure effectively assists the stacked paper to slide off the receiving structure, reducing the residual phenomenon caused by the light weight of the paper. This not only improves the stacking efficiency of the paper, but also reduces the waste of paper caused by the residual, thereby improving the overall economic benefits.

[0040] 2. Through the setting of the pushing structure, the automatic pushing of the stacked paper is realized, which improves the transfer efficiency and automation level of the stacking device. It can effectively avoid the problem of paper residue on the lifting plate and improve the transfer efficiency.

[0041] 3. Through the coordinated action of the spring and the damper, the movement of the push plate is smoother and more controllable, avoiding the impact and vibration caused by sudden acceleration or deceleration in the traditional pushing structure, thereby improving the stability and reliability of the pushing work. The elastic support of the spring can absorb and disperse the impact force generated by the stacked paper or the operation of the drive, protecting the stacked paper from damage.

[0049] The paper stacking device provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0050] Example 1:

[0051] like Figures 1 to 3 As shown, the embodiment of the present application provides a paper stacking device, including a stacking mechanism 100, and further including:

[0052] The conveyor belt 200 is provided on one side of the stacking device and is used to transport the paper;

[0053] The transfer mechanism is provided on the side of the conveyor belt 200 away from the stacking device, and is used to receive the paper sheets and transport the stacked paper sheets after stacking. The transfer mechanism includes:

[0054] The receiving structure 300 is used to receive paper;

[0055] The pushing structure 400 is provided on the receiving structure 300 and is used to assist in leading out the stacked paper sheets.

[0056] In some implementations of the embodiments of this application, Figure 1As shown, the above-mentioned paper stacking device is adopted, and by setting a conveyor belt 200, continuous and stable input of paper is achieved, providing a reliable basis for subsequent stacking operations. The combined use of the receiving structure 300 and the pushing structure 400 ensures that the stacked paper can be smoothly and efficiently exported, avoiding the problem of residual caused by the difficulty of the paper sliding off. The setting of the pushing structure 400 also effectively assists the stacked paper to slide off the receiving structure 300, reducing the residual phenomenon caused by the light weight of the paper. Not only is the stacking efficiency of the paper improved, but the waste of paper caused by residual is also reduced, thereby improving the overall economic benefits.

[0057] Furthermore, a universal wheel 360 is provided at the bottom of the frame 310 , and a plurality of universal wheels 360 are provided. A pushing handle 370 is also provided on the side wall of the frame 310 .

[0058] Multiple universal wheels 360 located at the bottom of the frame 310 provide the device with all-around mobility. A push handle 370 located on the side of the frame 310 provides a convenient grip for the operator, allowing them to easily push or pull the device. When moving the device, the operator can control its direction and speed by gripping the push handle 370, thus preventing accidents such as collisions and falls.

[0059] Example 2:

[0060] An embodiment of the present application provides a paper stacking device. In addition to the above-mentioned technical features, the paper stacking device of the embodiment of the present application also includes the following technical features.

[0061] like Figures 2 to 4 As shown, the receiving structure 300 includes:

[0062] The frame 310 has a receiving port 311 on its top and a receiving plate 312 on one side of the receiving port 311;

[0063] The lifting plate 320 has a first cylinder 321 and a second cylinder 322 spaced apart at its bottom;

[0064] The material guide port 330 is provided on the side wall of the frame 310 , and a blocking plate 340 is provided on the material guide port 330 ;

[0065] The output shafts of the first cylinder 321 and the second cylinder 322 are hinged to the lifting plate 320 .

[0066] In the embodiment of the present application, the frame 310 serves as the main part of the receiving structure 300. A receiving port 311 is provided on the top thereof for receiving the paper sheets from the conveyor belt 200. A receiving plate 312 is provided on one side of the receiving port 311. The receiving plate 312 plays a supporting and guiding role during the stacking process of the paper sheets. The lifting plate 320 is located inside the frame 310 and is used to carry the stacked paper sheets. A first cylinder 321 and a second cylinder 322 are provided at the bottom of the lifting plate 320 as a power source for lifting and lowering, and are used to adjust the height and tilt angle of the lifting plate 320. The guide port 330 is provided on the side wall of the frame 310 and serves as a guide channel for the stacked paper sheets. A blocking plate 340 is provided on the guide port 330 to keep the guide port 330 closed during the stacking process of the paper sheets and prevent the paper sheets from sliding off prematurely.

[0067] When the conveyor belt 200 delivers the paper sheets to the receiving port 311, the receiving plate 312 provides support, allowing the sheets to land smoothly on the lifting plate 320. As the sheets are stacked, the first and second cylinders 321 and 322 maintain the lifting plate 320 in a horizontal position, ensuring stability and neatness during the stacking process. Once stacking is complete, the lifting plate 320 is tilted by adjusting the output shaft lengths of the first and second cylinders 321 and 322. Due to the hinged design of the two cylinders, the lifting plate 320 can tilt at a certain angle, allowing the stacked sheets to slide toward the feed port 330 under the influence of gravity. Just before the sheets are ejected from the feed port 330, the blocking plate 340 is opened, leaving the feed port 330 open and allowing the sheets to slide smoothly. This receiving structure 300 ensures smooth receipt and stacking of the sheets, while utilizing the lifting and tilting functions of the cylinders to ensure smooth ejection of the stacked sheets from the feed port 330.

[0068] Example 3:

[0069] An embodiment of the present application provides a paper stacking device. In addition to the above-mentioned technical features, the paper stacking device of the embodiment of the present application also includes the following technical features.

[0070] like Figure 3 and Figure 4 As shown, the push structure 400 includes:

[0071] The push plate 410 is provided on one side of the lifting plate 320;

[0072] The driver 420 is provided at the bottom of the lifting plate 320, and its output shaft is connected to the push plate 410;

[0073] A slide groove 430 is provided on the lifting plate 320 and is used for sliding the push plate 410;

[0074] A connecting rod 440 adapted to the sliding groove 430 is provided at the bottom of the push plate 410 , and the connecting rod 440 is connected to the output shaft of the driver 420 .

[0075] In an embodiment of the present application, a push plate 410 is provided on one side of the lifting plate 320 for pushing the stacked paper sheets after stacking is completed. The push plate 410 has a certain rigidity and wear resistance to ensure that the paper sheets are not damaged during the pushing process. The driver 420 is provided at the bottom of the lifting plate 320 and serves as the power source of the pushing structure 400. Its output shaft is connected to the push plate 410, and the reciprocating motion of the push plate 410 is achieved through the operation of the driver 420. The chute 430 is provided on the lifting plate 320 for sliding the push plate 410. The connecting rod 440 is provided at the bottom of the push plate 410 and is adapted to the chute 430. One end of the connecting rod 440 is connected to the push plate 410, and the other end is connected to the output shaft of the driver 420. The power output of the driver 420 is achieved to the push plate 410 through the transmission effect of the connecting rod 440.

[0076] After the stack of paper sheets is completed on the lifting plate 320, the driver 420 begins to operate. The output shaft of the driver 420 drives the push plate 410 to slide within the chute 430 via the connecting rod 440. As the push plate 410 slides, it gradually approaches the stack of paper sheets until it contacts the paper sheets. At this point, the driver 420 continues to operate, and the push plate 410, driven by the connecting rod 440, pushes the stack of paper sheets toward the feed opening 330. As the push plate 410 continues to push, the stack of paper sheets gradually slides down the feed opening 330 under the influence of gravity and the push plate 410. During this process, the blocking plate 340 should remain open to ensure that the paper sheets can be smoothly discharged. When the stack of paper sheets is completely discharged from the feed opening 330, the driver 420 stops operating, and the push plate 410, driven by the connecting rod 440, returns to its initial position, awaiting the next stacking and pushing operation.

[0077] The automatic pushing of the drawn paper after stacking is realized, which improves the transfer efficiency and automation level of the stacking device, can effectively avoid the problem of drawn paper remaining on the lifting plate 320, and also improves the transfer efficiency.

[0078] Furthermore, the push structure 400 also includes:

[0079] The damper 450 is provided at the bottom of the lifting plate 320 and located on one side of the driver 420 , and the telescopic end of the damper 450 is connected to the connecting rod 440 ;

[0080] Spring 460, disposed at the bottom of the lifting plate 320 and connected to the connecting rod 440;

[0081] Among them, the spring 460 is set outside the damper 450. The cooperation of the spring 460 and the damper 450 can make the movement of the push plate 410 more stable, thereby making the pushing work more urgent and stable, and playing a protective role in the paper extraction startup.

[0082] The damper 450 is located at the bottom of the lifting plate 320 and on one side of the driver 420. Its telescopic end is connected to the connecting rod 440, providing appropriate resistance during the movement of the push plate 410, ensuring smoother movement and preventing shock and vibration caused by sudden acceleration or deceleration. A spring 460 is located at the bottom of the lifting plate 320 and connected to the connecting rod 440, and is positioned outside the damper 450. By providing elastic support, the push plate 410 has a certain buffering capacity during movement, absorbing and dissipating the impact force generated by the stacking of paper sheets or the operation of the driver 420. When the driver 420 is activated and drives the connecting rod 440 to move, the push plate 410 begins to push the stack of paper sheets. At this point, the damper 450 begins to operate, providing appropriate resistance to control the movement speed of the push plate 410 and prevent it from moving too fast or too slow. Simultaneously, the spring 460 also begins to function, providing elastic support for the push plate 410, allowing it to push the paper sheets smoothly. During the pushing process, if resistance or uneven distribution of stacked paper is encountered, the spring 460 can absorb part of the impact force to protect the push plate 410 and the stacked paper from damage, while the damper 450 can maintain the stability of the movement of the push plate 410 to avoid excessive vibration and noise.

[0083] The coordinated action of spring 460 and damper 450 ensures smooth and controllable movement of push plate 410, avoiding the shock and vibration caused by sudden acceleration or deceleration in conventional push mechanism 400, thereby improving the stability and reliability of the push operation. Furthermore, the elastic support provided by spring 460 absorbs and disperses the impact force from the stacking of paper sheets or the operation of driver 420, protecting the stacked paper sheets from damage. Furthermore, the resistance control provided by damper 450 prevents push plate 410 from inflicting excessive pressure or friction on the stacked paper sheets, thereby maintaining the integrity and quality of the paper sheets.

[0084] Example 4:

[0085] An embodiment of the present application provides a paper stacking device. In addition to the above-mentioned technical features, the paper stacking device of the embodiment of the present application also includes the following technical features.

[0086] As shown in the figure, a driving motor 350 connected to the blocking plate 340 is provided on the side wall of the frame 310 , and the blocking plate 340 can be controlled to open and close by the driving motor 350 .

[0087] In this embodiment of the present application, the drive motor 350 is mounted on the side wall of the frame 310 and connected to the blocking plate 340 via a rotating shaft. When the stack of paper sheets needs to be discharged, the control system sends an on signal to the drive motor 350. Upon receiving the signal, the drive motor 350 begins to operate, driving the blocking plate 340 to one side via a transmission mechanism, thereby opening the feed opening 330. When the paper sheets have been completely discharged, the control system sends a off signal to the drive motor 350, causing it to operate again, pulling the blocking plate 340 back into position via the transmission mechanism, thereby closing the feed opening 330.

[0088] The use of the drive motor 350 realizes the control of the opening and closing action of the blocking plate 340, ensuring that the stacked paper can be discharged at the correct time and position, avoiding the problem of paper residue or scattering caused by inaccurate action of the blocking plate 340.
