Description

Technical Field

[0001] The present invention relates to the technical field of wiping paper, and in particular to a production process and a preparation device for highly efficient degradable industrial wiping paper. Background Art

[0002] Wiping paper, also known as industrial wiping paper, is strong and durable, and has high water and oil absorption properties. Due to the excellent properties of wiping paper, it is widely used for cleaning and wiping in industries, chemical laboratories and other fields.

[0003] When existing equipment produces highly degradable industrial wiping paper, it is generally first processed into a giant roll of paper, and then the highly degradable industrial wiping paper on the giant roll is unwound and printed, and then rolled into small rolls and cut.

[0004] However, during the unwinding process of the giant roll of paper, if the giant roll of paper is unwound, it is often necessary to stop the machine when replacing the giant roll of paper. In this process, the high-efficiency degradable industrial wiping paper on the replaced giant roll of paper needs to be placed along the moving trajectory of the original high-efficiency degradable industrial wiping paper, and then restarted, which results in low production efficiency. Summary of the Invention

[0005] In order to solve at least one of the technical problems mentioned in the background technology, the purpose of the present invention is to provide a high-efficiency degradable industrial wiping paper production process and preparation device, which facilitates the replacement of giant rolls of paper without stopping the machine and improves production efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solutions: a highly efficient degradable industrial wiping paper preparation device, comprising a base, a frame fixedly mounted on the base, a rotating shaft rotatably mounted on the frame, two turntables fixedly mounted on the surface of the rotating shaft, a first winding shaft and a second winding shaft rotatably mounted between the two turntables, a pressure sensing mechanism and a pressing mechanism, as well as a printing mechanism and a slitting mechanism, respectively, provided on one side of the turntable along the moving direction of the wiping paper, and a controller mounted on the base;

[0008] Furthermore, a first motor for driving the rotating shaft to rotate is installed on the frame, a second motor for driving the first winding shaft to rotate is installed on the turntable, and a third motor for driving the second winding shaft to rotate is installed on the turntable.

[0009] Furthermore, the pressing mechanism includes an upper cover plate and a lower cover plate, the upper cover plate is fixedly connected to the frame, and an electric telescopic cylinder is fixedly installed on the lower side of the lower cover plate.

[0010] Furthermore, a first roller is rotatably mounted on the lower side of the upper cover plate, and a second roller is rotatably mounted on the upper side of the lower cover plate.

[0011] Furthermore, there are at least two first rollers and at least two second rollers, and the first rollers and the second rollers are staggered.

[0012] Furthermore, the bearing block is slidably arranged in the chamber, and a limit block for supporting the bearing block is fixedly installed on the inner wall of the chamber. When the pressure plate is not in contact with the pressure sensor, the bearing block is in a stationary state relative to the shell.

[0013] Furthermore, a plurality of sockets communicating with the chamber are provided on the upper side of the shell, and a counterweight block is slidably provided in at least one of the sockets, and the counterweight block abuts against the upper side of the bearing block.

[0014] Furthermore, in the initial state, the first reel is located on the upper side of the turntable, and the second reel is located on the lower side of the turntable. The wiping paper on the first reel located on the upper side of the turntable is processed by the pressure sensing mechanism, the pressing mechanism, the printing mechanism, and the winding and slitting mechanism, while the leading end of the wiping paper on the second reel located on the lower side of the turntable is located at the pressing mechanism.

[0015] S1. The first reel is installed on the upper side of the turntable. The second motor drives the first reel to rotate. The first reel releases the wiping paper. The wiping paper moves through the pressure sensing mechanism, the pressing mechanism, the printing mechanism and the winding and slitting mechanism for processing.

[0016] S2. The second winding shaft is installed on the lower side of the turntable, and the leading end of the wiping paper on the second winding shaft is placed in the pressing mechanism;

[0017] S3. After the wiping paper on the first reel is released, the roller moves downward under the action of gravity.

The controller controls the pressing mechanism to operate, driving the leading end of the wiping paper on the second reel to adhere to the trailing end of the wiping paper on the upper side of the first reel, thereby completing the splicing of the wiping paper.

[0018] S4. When the pressure sensing mechanism is no longer pressurized by the wiping paper, the controller controls the third motor to rotate the second winding shaft, so that the second winding shaft starts to unwind;

[0019] S5. When the pressure sensing mechanism is no longer pressurized by the wiping paper, the first motor drives the rotating shaft to rotate, thereby exchanging the positions of the first winding shaft and the second winding shaft;

[0020] S6. During the process of the second reel moving to the first reel, the wiping paper on the second reel presses the pressure sensing mechanism again, and the pressure sensing mechanism transmits an electrical signal to the controller, which controls the pressing mechanism to open;

[0021] S7. Remove the first winding shaft on the lower side of the turntable, replace it with a new winding shaft, and place the leading end of the wiping paper on the new winding shaft into the pressing mechanism.

[0022] Compared with the prior art, the present invention has the following beneficial effects: the first reel rotates to release the wiping paper, and the wiping paper passes through the pressure sensing mechanism and the pressing mechanism, and then passes through the printing mechanism for processing and printing, and then the printed reel is reeled and cut by the reeling and slitting mechanism. The pressure sensing mechanism senses the tension of the wiping paper, and the leading end of the wiping paper on the second reel is adhered with a double-sided adhesive tape located in the pressing mechanism, waiting to be bonded with the trailing end of the wiping paper on the first reel. When the wiping paper on the first reel is released and the pressure sensing mechanism no longer senses the force applied by the wiping paper, the pressure sensing mechanism releases an electrical signal to the controller, and the controller controls the pressure mechanism to start pressing, so that the leading end of the wiping paper on the second reel contacts and bonds with the trailing end of the wiping paper on the first reel, thereby realizing the continuation of the wiping paper.

DETAILED DESCRIPTION

[0030] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0031] See also Figure 1 、 Figure 2 and Figure 3 The present embodiment provides a highly efficient degradable industrial wiping paper preparation device, comprising a base 1, a frame 2 fixedly mounted on the base 1, a rotating shaft 3 rotatably mounted on the frame 2, two turntables 4 fixedly mounted on the surface of the rotating shaft 3, a first winding shaft 5 and a second winding shaft 6 rotatably mounted between the two turntables 4, a pressure sensing mechanism 7, a pressing mechanism 8, a printing mechanism and a slitting mechanism (not shown in the figure) are respectively provided on one side of the turntable 4 along the moving direction of the wiping paper, and a controller is also included, wherein the pressure sensing mechanism 7 and the pressing mechanism 8 are both electrically connected to the controller by signals.

[0032] When converting highly biodegradable industrial wipes (hereinafter referred to as wipes) into rolls, the reeled jumbo wipes are processed. Because the jumbo wipes have no patterns or markings on their surface, they are much tougher than the processed rolls. The first or second reel 5 or 6 reels contain the desired wiping paper, specifically the highly biodegradable industrial wipes to be printed.

[0033] See also Figure 1 and Figure 2 A first motor 9 for driving the rotating shaft 3 is installed on the frame 2, a second motor 10 for driving the first winding shaft 5 is installed on the turntable 4, and a third motor 11 for driving the second winding shaft 6 is installed on the turntable 4.

[0034] One of the first reel 5 or the second reel 6 rotates. In this embodiment, the first reel 5 rotates, thereby releasing the wiping paper. The wiping paper passes through the pressure sensing mechanism 7 and the pressing mechanism 8, and then passes through the printing mechanism for processing and printing. The printed roll paper is then reeled and cut by the reeling and slitting mechanism. The pressure sensing mechanism 7 senses the tension of the wiping paper, and the double-sided adhesive tape is adhered to the leading end of the wiping paper on the second reel 6 and is located in the pressing mechanism 8, waiting to be bonded with the trailing end of the wiping paper on the first reel 5. When the wiping paper on the first reel 5 is released and the pressure sensing mechanism 7 no longer senses the force applied by the wiping paper, the pressure sensing mechanism 7 releases an electrical signal to the controller, which controls the pressure mechanism to start pressing, so that the leading end of the wiping paper on the second reel 6 contacts and bonds with the trailing end of the wiping paper on the first reel 5, thereby realizing the continuation of the wiping paper. At the same time, the third motor 11 drives the second reel 6 to rotate, releasing the wiping paper.

[0035] When the second material reel 6 starts to release the wiping paper, the first motor 9 drives the rotating shaft 3 to rotate slowly, that is, drives the first material reel 5 and the second material reel 6 on the turntable 4 to rotate slowly, and its speed is 0.5 rpm, thereby driving the wiping paper on the second material reel 6 to gradually approach the pressure sensing mechanism 7, and makes the wiping paper squeeze the pressure sensing mechanism 7, so that the pressure sensing mechanism 7 sends an electrical signal to the controller, and the controller controls the pressing mechanism 8 to open. After the turntable 4 rotates to the point where the positions of the first material reel 5 and the second material reel 6 are interchanged, the turntable 4 stops rotating;

[0036] At this time, the first reel 5 can be replaced manually, and the double-sided adhesive tape is glued to the head end of the wiping paper on the new reel and placed in the pressure mechanism, and the wiping paper on the second reel 6 is released and then glued to the tail end of the wiping paper on the second reel 6. This cycle is repeated to achieve the effect of automatically replacing the reel without stopping the machine.

[0037] In the initial state, the first and second reel shafts 5 and 6 are vertically positioned on either side of the rotating shaft 3, respectively. The wiping paper on the first or second reel shaft 5 and 6 on the upper side contacts the pressure sensing mechanism 7. In this embodiment, the first reel shaft 5 is positioned above the rotating shaft 3, so that the wiping paper on the first reel shaft 5 contacts the pressure sensing mechanism 7. After the wiping paper on the first reel shaft 5 is released, the turntable 4 rotates, and the first and second reel shafts 5 and 6 swap positions, so that the first reel shaft 5 is positioned on the lower side. Since the lower side is lower, it is convenient to replace the first reel shaft 5.

[0038] See also Figure 1 、 Figure 2 and Figure 4The pressure sensing mechanism 7 includes a shell 71 fixedly mounted on the frame 2, a chamber 72 is opened in the shell 71, a supporting block 73 is provided in the chamber 72, a pressure sensor 74 is installed on the supporting block 73, a telescopic rod 75 is fixedly mounted on the lower side of the supporting block 73, a pressure plate 76 is fixedly mounted on the lower side of the telescopic rod 75, and two connecting frames 77 extending to the outside of the shell 71 are fixedly mounted on the lower side of the pressure plate 76, and a roller 78 is rotatably mounted between the two connecting frames 77 and located below the shell 71.

[0039] In the initial state, the wiping paper on the second winding shaft 6 is located below the pressure sensing mechanism 7. When the turntable 4 rotates and drives the first winding shaft 5 and the second winding shaft 6 to rotate around the axis of the turntable 4, the second winding shaft 6 gradually moves toward the upper side of the turntable 4, so that the wiping paper on the second winding shaft 6 gradually approaches the pressure roller 78 and contacts the roller 78. When the wiping paper is released and moves, the surface of the wiping paper has tension, so that when the wiping paper contacts the roller 78, the wiping paper will have an upward thrust on the roller 78, so that the roller 78 is forced to drive the connecting frame 77 and the pressure plate 76 to move upward, so that the pressure plate 76 squeezes the pressure sensor 74, and the pressure sensor 74 is pressurized to transmit an electrical signal to the controller. The controller controls the pressing mechanism 8 to open, thereby facilitating the movement of the wiping paper on the second winding shaft 6.

[0040] See also Figure 1 、 Figure 2 and Figure 5 The pressing mechanism 8 includes an upper cover plate 81 and a lower cover plate 82 . The upper cover plate 81 is fixedly connected to the frame 2 , and an electric telescopic cylinder 83 is fixedly installed on the lower side of the lower cover plate 82 .

[0041] The lower cover 82 is driven up and down by the electric telescopic cylinder 83, so that the upper cover 81 and the lower cover 82 are squeezed open and closed. Before the wiping paper on the first reel 5 is released, the wiping paper on the first reel 5 passes between the upper cover 81 and the lower cover 82, and the head end of the wiping paper on the second reel 6 is located on the upper side of the lower cover 82. When the wiping paper needs to be replaced, the pressure sensing mechanism 7 transmits an electrical signal to the controller, and the controller controls the electric telescopic cylinder 83 to extend and retract, driving the lower cover 82 to move in the direction of the upper cover 81, and then driving the wiping paper on the second reel 6 on the lower cover 82 to contact the wiping paper on the first reel 5, so that the double-sided adhesive on the head end of the wiping paper on the second reel 6 will adhere to the wiping paper on the first reel 5, so that the head end of the wiping paper on the second reel 6 is bonded to the tail end of the wiping paper on the first reel 5, completing the connection.

[0042] However, the wiping paper may come into contact with the upper cover plate 81 or the lower cover plate 82 between the upper cover plate 81 and the lower cover plate 82 , so that the upper cover plate 81 and the lower cover plate 82 may be easily damaged by friction.

[0043] See also Figure 1 、 Figure 5 and Figure 6 In order to solve the above technical problems, a first roller 84 is rotatably mounted on the lower side of the upper cover 81, and a second roller 85 is rotatably mounted on the upper side of the lower cover 82.

[0044] When the wiping paper passes between the upper cover 81 and the lower cover 82, it only contacts the first roller 84 or the second roller 85. When the moving wiping paper contacts the first roller 84 or the second roller 85, the first roller 84 or the second roller 85 rotates, so that the friction experienced by the wiping paper in the pressing mechanism 8 is rolling friction, which reduces the wear of the wiping paper.

[0045] However, when the lower cover 82 drives the head end of the wiping paper on the second reel 6 to move upward, the second reel 6 begins to rotate to release the wiping paper, thereby preventing the wiping paper on the second reel 6 from being pulled and broken by the wiping paper on the first reel 5. However, because the initial outer diameter of the wiping paper on the second reel 6 is larger, the initial length of the wiping paper released by the second reel 6 is longer at the same speed within the same time, which easily leads to insufficient pre-tightening force of the wiping paper.

[0046] See also Figure 1 、 Figure 5 and Figure 6 There are at least two first rollers 84 and at least two second rollers 85 , and the first rollers 84 and the second rollers 85 are staggered.

[0047] When the second roller 85 moves upward with the lower cover 82, the second roller 85 is staggered with the first roller 84, so that when the wiping paper moves between the first roller 84 and the second roller 85, the wiping paper is wavy, so that the speed direction of the wiping paper between the first roller 84 and the second roller 85 is changing. On the one hand, it is convenient for the head end of the wiping paper on the second winding shaft 6 to adhere to the tail end of the wiping paper on the first winding shaft 5, thereby improving the adhesion. On the other hand, the wiping paper bends forward inside the first roller 84 and the second roller 85, thereby increasing the contact area with the first roller 84 and the second roller 85, and then increasing the friction force exerted on the wiping paper between the first roller 84 and the second roller 85, thereby providing pre-tightening force to the wiping paper and reducing the occurrence of scattering and deviation of the wiping paper.

[0048] As the second winding shaft 6 gradually moves toward the upper side of the turntable 4, the wiping paper on the second winding shaft 6 also gradually approaches the pressure sensing mechanism 7 and contacts the roller 78 on the pressure sensing mechanism 7. When the second winding shaft 6 moves to the upper side of the turntable 4, the wiping paper force on the second winding shaft 6 also acts on the roller 78, and pushes the roller 78 to drive the connecting frame 77 and the pressure plate 76 to move upward until the pressure plate 76 squeezes the pressure sensor 74. At this time, the pressure sensor 74 feels the pressure, and thereby drives the lower cover 82 to move downward through the electric telescopic cylinder 83, so that the lower cover 82 gradually moves away from the upper cover 81, and the wiping paper on the second winding shaft 6 is transported outward through the roller 78 and the first roller 84.

[0049] Because the pressure sensing mechanism 7 is close to the turntable 4, the roller 78 of the pressure sensing mechanism 7 also guides the wiping paper. Therefore, if the position of the guide roller of the subsequent process of the wiping paper changes during the transportation process or the outer diameter of the winding changes, the speed of the wiping paper will also change, and the tension of the wiping paper will also need to change accordingly, otherwise the wiping paper will easily break.

[0050] See also Figure 1 and Figure 4 In order to solve the above technical problems, the supporting block 73 is slidably set in the chamber 72, and a limit block 79 for supporting the supporting block 73 is fixedly installed on the inner wall of the chamber 72. When the pressure plate 76 is not in contact with the pressure sensor 74, the supporting block 73 is in a stationary state relative to the shell 71.

[0051] The wiping paper contacts the roller 78, and the roller 78 drives the connecting frame 77 and the pressure plate 76 to move upward to squeeze the pressure sensor 74. Because the wiping paper force is large, the force on the roller 78 is large, which will push the roller 78, the connecting frame 77, the pressure plate 76, the pressure sensor 74 and the supporting block 73 to move upward together until the wiping paper force is balanced with the gravity of the roller 78, the connecting frame 77, the pressure plate 76, the pressure sensor 74 and the supporting block 73. During the movement of the wiping paper, if the wiping paper force changes, for example, the wiping paper force becomes smaller, then the roller 78, the connecting frame 77, the pressure plate 76, the pressure sensor 74 and the supporting block 73 will move upward. Under the action of gravity of the pressure sensor 74 and the supporting block 73, the roller 78 gradually moves downward, thereby increasing the tension of the wiping paper. If the wiping paper force becomes greater, the wiping paper pushes the roller 78, the connecting frame 77, the pressure plate 76, the pressure sensor 74 and the supporting block 73 to continue to move upward, thereby releasing excess wiping paper force, and then plays a role in adjusting the tension of the wiping paper. If the tension adjustment is not in the pressure sensing mechanism 7, then when the wiping paper force is loose, the pressure on the roller 78 will decay or even disappear, and errors will occur when the wiping paper on the first winding shaft 5 and the second winding shaft 6 are connected.

[0052] Because different wiping papers have different thicknesses and materials, the required tension is different.

[0053] See also Figure 1 and Figure 4 In order to solve the above technical problems and adapt to different wiping paper forces, the upper side of the housing 71 is provided with a plurality of sockets 710 communicating with the chamber 72 , and at least one of the sockets 710 is slidably provided with a counterweight 711 , which abuts against the upper side of the bearing block 73 .

[0054] According to the thickness or material of different wiping papers, a corresponding number of counterweight blocks 711 are selected to adjust the force of the wiping paper.

[0055] The pressure sensor 74 , the electric telescopic cylinder 83 , the first motor 9 , the second motor 10 , and the third motor 11 are all connected to the controller via electrical signals.

[0056] Working principle: In the initial state, the first winding shaft 5 is on the upper side of the turntable 4, and the second winding shaft 6 is on the lower side of the turntable 4. The wiping paper on the first winding shaft 5 on the upper side of the turntable 4 is processed by the pressure sensing mechanism 7, the pressing mechanism 8, the printing mechanism and the winding and slitting mechanism, while the head end of the wiping paper on the second winding shaft 6 on the lower side of the turntable 4 is located at the pressing mechanism 8.

[0057] S1. The first reel 5 is mounted on the upper side of the turntable 4. The second motor 10 drives the first reel 5 to rotate. The first reel 5 releases the wiping paper, which moves through the pressure sensing mechanism 7, the pressing mechanism 8, the printing mechanism, and the winding and slitting mechanism for processing.

[0058] S2, the second winding shaft 6 is installed on the lower side of the turntable 4, and the leading end of the wiping paper on the second winding shaft 6 is placed in the pressing mechanism 8;

[0059] S3. After the wiping paper on the first reel 5 is released, the roller 78 moves downward under the action of gravity. The pressure sensor 74 is no longer pressurized by the wiping paper, so an electrical signal is transmitted to the controller. The controller controls the pressing mechanism 8 to operate, driving the leading end of the wiping paper on the second reel 6 to adhere to the trailing end of the wiping paper on the upper side of the first reel 5, thereby completing the splicing of the wiping paper.

[0060] S4, when the pressure sensing mechanism 7 is no longer pressurized by the wiping paper, the controller controls the third motor 11 to drive the second winding shaft 6 to rotate, so that the second winding shaft 6 starts to unwind;

[0061] S5. When the pressure sensing mechanism 7 is no longer pressurized by the wiping paper, the first motor 9 drives the rotating shaft 3 to rotate, thereby exchanging the positions of the first winding shaft 5 and the second winding shaft 6;

[0062] S6. During the process of the second reel 6 moving to the first reel 5, the wiping paper on the second reel 6 presses the pressure sensing mechanism 7 again, and the pressure sensing mechanism 7 transmits an electrical signal to the controller, which controls the pressing mechanism 8 to open;

[0063] S7, remove the first winding shaft 5 on the lower side of the turntable 4, replace it with a new winding shaft, and place the leading end of the wiping paper on the new winding shaft into the pressing mechanism 8.

[0064] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced therein.
