Abstract
Description
Technical Field
[0001] This invention relates to the field of toilet paper production equipment technology, and in particular to a fully automatic toilet paper roll core replacement mechanism. Background Technology
[0002] Paper winding machines are core equipment in the paper processing industry for winding and forming paper. They are widely used in the large-scale production of toilet paper. The winding operation of this type of paper winding machine mainly relies on the pressing force formed by the weight of the winding roller itself, combined with the friction force generated by the rotation of the pressure roller and guide roller as the power source for paper winding. This drives the paper to make a uniform winding motion along the circumference of the winding roller. Through this transmission winding method, the density and flatness of the paper winding can be effectively guaranteed, so that the gap between the layers of the formed paper roll is uniform, which greatly improves the quality of the finished paper winding and achieves uniform paper winding and forming.
[0003] In the actual continuous production operation of a paper winding machine, once the paper on the winding roller has been wound to the preset specifications such as roll diameter and weight, the winding roller needs to be replaced in time to continue the subsequent winding operation. Currently, when replacing the winding roller after the winding is completed, paper winding machines generally adopt a manual operation method in conjunction with a crane. The specific operation process is as follows: after the winding roller has wound the paper to meet the winding requirements, the overall operation of the paper winding machine is paused. Then, the finished winding roller that has been wound is removed from the paper winding machine station by the lifting action of the crane. Subsequently, the empty winding roller is lifted to the paper winding station by the crane, and the positioning and installation of the winding roller are completed manually.
[0004] The above-mentioned methods for replacing paper rolls have obvious technical defects. On the one hand, the disassembly, hoisting, and installation of paper rolls require the paper winding machine to be stopped and waited for the entire process, which directly interrupts the continuous production process of paper winding and significantly reduces the overall production efficiency of paper winding, making it difficult to adapt to the large-scale and continuous production needs of modern paper production. On the other hand, during the shutdown and restart of the paper winding machine, the paper conveying and winding rhythm is disrupted, which can easily lead to problems such as paper deviation, paper breakage, and loose winding, resulting in excessive paper loss, significantly increasing the raw material cost of paper production, and causing excessive paper waste.

Detailed Implementation
[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0022] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0023] like Figure 1As shown, an automatic toilet paper roll core replacement mechanism includes: a support frame 1; two support frames 1 are arranged opposite each other; a guide roller 2; the two ends of the guide roller 2 are rotatably connected between the two support frames 1 via bearing seats 3 and are close to the paper feeding end of the support frame 1; the guide roller 2 is driven by a motor 4; a pressure roller 5; the two ends of the pressure roller 5 are rotatably connected between the two support frames 1 via bearing seats 6 and are located above the guide roller 2; a replacement roller 7; the replacement roller 7 is located at the paper output end of the pressure roller 5 and is close to the guide roller 2; the replacement roller 7 is covered with double-sided adhesive. A pressure roller mechanism 8 is used to bring the replacement roller 7 into contact with or separate it from the guide roller 2. The pressure roller mechanism 8 is located at both ends of the replacement roller 7 and connected to the support frame 1. A paper roll 9 is located at the paper outlet end of the guide roller 2 and at the lower end of the replacement roller 7. A guide mechanism 10 is used to limit and guide the paper roll 9 to the paper outlet end of the support frame 1 and then reset it. The guide mechanism 10 is connected to the support frame 1 and connected to both ends of the paper roll 9. A rotation mechanism 11 is used to guide the paper roll 9 to the ground and then reset it. The rotation mechanism 11 is located at the paper outlet end of the support frame 1.
[0024] In this invention, when the paper roll 9 needs to be replaced after it reaches the preset requirements, the paper roll 9 is moved to the rotating mechanism 11 by the guiding mechanism 10. During this process, the pressure roller mechanism 8 brings the replacement roller 7 into contact with the guide roller 2 to become a new paper roll. While the replacement roller 7 is rolling paper, the paper roll 9 breaks the paper. After the replacement roller 7 has rolled paper a certain number of times, the pressure roller mechanism 8 moves the replacement roller 7 to contact the guiding mechanism 10. At this time, the roll replacement is completed. The paper roll 9 that has reached the preset requirements is transferred to the ground or a conveyor vehicle by the rotating mechanism 11. The replacement of the paper roll 9 can be achieved without stopping the paper rolling machine, which improves work efficiency.
[0025] like Figure 1 , Figure 4 as well as Figure 8As shown, the pressure roller mechanism 8 includes a rotating block 801, a cylinder 802, a U-shaped component 803, a connecting plate 804, a swing arm 805, a bearing seat 806, a rotating shaft 807, an elastic component 808, a second cylinder 809, a second U-shaped component 8010, and a second swing arm 8011; the rotating block 801 is rotatably connected to the support frame 1; the cylinder 802 is fixed to the top surface of the rotating block 801, and its pushing end faces upward; the closed end of the U-shaped component 803 is fixed to the pushing end of the cylinder 802, and the connecting plate 804 is hinged inside its open end; the top of the connecting plate 804 is integrally connected to the swing arm 805; the swing arm 805 has a through hole 801 and a placement groove 8051, the through hole 801 is near its bottom end, and the placement groove 8051 is connected to its top end to form an upper support arm 8052 and a lower support arm 8053; the swing arm 805... 05 A rotating shaft 807 is fixedly connected through a through hole 1; a bearing housing 3 806 is fixed to the top surface of bearing housing 3, and the inner ring of the bearing housing 3 806 is fixed to the rotating shaft 807; an elastic component 808 is disposed in a placement groove 8051 and one end is fixed to the bottom of the placement groove 8051; a cylinder 2 809 is fixed to a swing arm 1 805, and the pushing end of the cylinder 2 809 faces the same direction as the opening end of the swing arm 1 805; the pushing end of the cylinder 2 809 is fixed to the closed end of the U-shaped part 2 8010; the swing arm 2 8011 is T-shaped, one end of its horizontal bar is hinged to the opening end of the U-shaped part 2 8010, and its vertical bar is hinged to the upper support arm 8052; the two ends of the replacement roller 7 and the paper roll 9 are respectively connected to abutment parts 13; the middle position of the abutment parts 13 at both ends of the replacement roller 7 is located between the swing arm 2 8011 and the elastic component 808.
[0026] In this invention, Figure 4 For relative Figure 1 The pressure roller mechanism on the right side is 8; Figure 4 As can be seen, the connecting plate 804 is divided into upper and lower parts. Due to the certain lateral distance between the bearing housing 806 and the U-shaped part 803, the upper plate is tilted towards the outside of the support frame 1 and connected to the lower plate. The lower plate is hinged to the open end of the U-shaped part 803. Figure 4Based on this, it can be seen that the cylinder 802 moves up and down, simultaneously driving the U-shaped component 803 to move up and down. Since the top of the connecting plate 804 is integrally connected to the swing arm 805, and the connecting plate 804 is hinged to the U-shaped component 803, when the U-shaped component 803 moves upward, the swing arm 805 moves counterclockwise in an arc around the pivot 807. Simultaneously, due to the hinged relationship between the connecting plate 804 and the U-shaped component 803, the lower plate of the connecting plate 804 moves around the hinge axis. The axis moves in a counterclockwise arc. When the U-shaped part 803 moves downward, the swing arm 805 moves in a clockwise arc with the rotating shaft 807 as the axis. At the same time, the connecting plate 804, due to its hinged relationship with the U-shaped part 803, moves in a clockwise arc with the hinge shaft as the axis. When moving in an arc, the replacement roller 7 contacts the guide roller 2. The maximum stroke of the cylinder 802 moving upward is when it moves in a counterclockwise arc to the bearing 1302 and into the slide groove 10011. Figure 4 The diagram shows the maximum stroke of cylinder 809. Cylinder 809 moves linearly. Since one end of the horizontal bar of swing arm 8011 is hinged to the open end of U-shaped part 8010, and its vertical bar is hinged to the upper support arm 8052, the vertical bar of swing arm 8011 moves in an arc around the hinge axis, and the horizontal bar of swing arm 8011 moves in an arc around the hinge axis at the open end of U-shaped part 8010. When the cylinders 1301 on both sides of the replacement roller 7 are placed in the placement groove 8051, the replacement roller 7 does not contact the guide roller 2. After the push rod of cylinder 809 pushes, the movement of swing arm 8011 applies pressure to cylinder 1301, and due to the elastic properties of elastic component 808, the replacement roller 7 comes into contact with the guide roller 2. When the push rod of cylinder 802 pushes up and down, rotating block 801 rotates relative to it.
[0027] like Figure 4 As shown, the elastic component 808 includes a fixing block 8081, a spring 8082, and a sliding plate 8083; the fixing block 8081 has a through hole 2; the fixing block 8081 is fixed to the swing arm 805 through the placement groove 8051; one end of the spring 8082 is fixed to the fixing block 8081 through the through hole 2; the other end of the spring 8082 faces the swing arm 8011 and is fixed to the sliding plate 8083; the inner sides of the upper support arm 8052 and the lower support arm 8053 are respectively provided with a sliding groove 1, and the sliding plate 8083 is slidably connected to the upper support arm 8052 and the lower support arm 8053 through the sliding groove 1 respectively.
[0028] In this invention, it should be noted that the spring 8082 is common knowledge in the art, and its elastic strength and other properties are not limited, as long as they can achieve the technical solution of this application; the sliding plate 8083 slides along the first groove, ensuring that the second swing arm 8011 moves as described above. Figure 4 The stability of the cylindrical 1301 when compressing the spring is shown in the indicated state.
[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the guiding mechanism 10 includes a guide block 1001, a swing arm 1002, a rotating shaft 1003, a bearing seat 1004, a cylinder 1005, a U-shaped part 1006, a connecting plate 1007, and a rotating block 1008; the guide block 1001 is fixed to the support frame 1; a sliding groove 10011 is provided on the top surface of the guide block 1001, and the abutment parts 13 at both ends of the paper roll 9 are slidably connected to the guide block 1001 through the sliding groove 10011; a placement groove 2 for accommodating the abutment parts 13 at both ends of the paper roll 9 is provided at the top of the swing arm 1002; a through hole 3 is provided at the bottom of the swing arm 1002; the rotating shaft 1005... 03 is fixed to the swing arm 1002 through the through hole 3; the bearing seat 1004 is fixed to the support frame 1; the inner ring of the bearing of the bearing seat 1004 is fixed to the rotating shaft 1003; the rotating block 1008 is rotatably connected to the support frame 1; the cylinder 1005 is fixed to the end face of the rotating block 1008 facing the paper output end, and the pushing end faces the middle position of the swing arm 1002; the pushing end of the cylinder 1005 is fixed to the closed end of the U-shaped part 1006; the connecting plate 1007 is integrally connected to the middle position of the swing arm 1002; the connecting plate 1007 is hinged to the U-shaped part 1006 through the open end of the U-shaped part 1006.
[0030] In this invention, the guide block 1001 is connected to the paper output end of the guide block 1001 through a sliding groove 10011. The paper input end of the guide block 1001 is a closed end. The guide block 1001 limits and guides the paper roll 9. When the paper roll 9 moves towards the paper output end to the open end of the guide block 1001, the paper roll 9 disengages from the guide block 1001. The push rod of the cylinder 1005 moves linearly. Due to the hinged relationship between the connecting plate 1007 and the U-shaped part 1006, the connecting plate 1007 moves in an arc around the hinge axis. The swing arm 1002 moves in an arc around the pivot 1003. The maximum distance of the arc is when the upper end of the swing arm 1002 moves to coincide with the rotating rod 1103. At this time, the top of the two actuating rods at the top of the swing arm 1002 is lower than the bottom of the clamping plate 1104. Since the rotating mechanism 11 drives the paper roll 9 to rotate toward the bottom surface, the paper roll 9 and the swing arm 1002 continue to contact and interfere when the rotating mechanism 11 rotates. When the push rod of the cylinder 1005 moves in a straight line, the rotating block 1008 rotates relative to it.
[0031] like Figure 1 , Figure 2 and Figure 6As shown, the rotating mechanism 11 includes a bearing housing 1101, a rotating shaft 1102, a rotating rod 1103, a clamping plate 1104, a rotating block 1105, a cylinder 1106, a connecting plate 1107, and a U-shaped component 1108; the bearing housing 1101 is fixed to the support frame 1; the inner ring of the bearing in the bearing housing 1101 is fixedly connected to the rotating shaft 1102; the rotating rod 1103 has a through hole 4, which is located near the bottom end of the rotating rod 1103; the rotating rod 1103 is fixed to the rotating shaft 1102 through the through hole 4; the rotating rod 1103... The top end is fixed to the clamping plate 1104; the clamping plate 1104 is arc-shaped, and the arc-shaped opening faces the paper roll 9; the rotating block 3 1105 is rotatably connected to the support frame 1; the end face of the rotating block 3 1105 facing the paper output end is fixed with the cylinder 4 1106; the pushing end of the cylinder 4 1106 faces the rotating rod 1103; the end face of the rotating rod 1103 away from the paper output end is fixed with the connecting plate 3 1107; the closed end of the U-shaped part 4 1108 is fixed to the pushing end of the cylinder 4 1106; the U-shaped part 4 1108 is hinged to the connecting plate 3 1107 through its open end.
[0032] In this invention, after the paper roll 9 disengages from the guide block 1001, the cylindrical parts 1301 at both ends of the paper roll 9 come into contact with the clamping plate 1104. The push rod of the cylinder 1106 moves linearly, and the U-shaped part 1108 moves linearly at the same time. Due to the hinge relationship between the U-shaped part 1108 and the connecting plate 1107, the connecting plate 1107 moves in an arc around the hinge axis. At the same time, the rotating rod 1103 moves in an arc around the rotating shaft 1102. When the push rod of the cylinder 1106 moves linearly, the rotating block 1105 rotates relative to it. The inner arc groove of the clamping plate 1104 is adapted to the shape of the cylindrical part 1301, and when the rotating rod 1103 moves in an arc, the clamping plate 1104 provides support for the cylindrical part 1301.
[0033] like Figure 2As shown, the support frame 1 includes a first horizontal bar 101, a second horizontal bar 102, a first vertical bar 103, a second vertical bar 104, and a third vertical bar 105; the bottom ends of the first vertical bar 103, the second vertical bar 104, and the third vertical bar 105 are integrally connected to the second horizontal bar 102, forming a mountain-shaped structure, and their top ends are integrally connected to the first horizontal bar 101; the top surface of the first horizontal bar 101 is fixed to the bearing seat 3; an L-shaped support rod 12 is integrally connected to the top surface of the first horizontal bar 101; the L-shaped support rod 12 is located at the paper feed end of the first horizontal bar 101 and the bearing seat 3. Between 3; the top surface of L-shaped support rod 12 is fixed to bearing seat 2 6; the outer side of vertical rod 3 105 is rotatably connected to rotating block 1 801 and rotating block 2 1008, with rotating block 1 801 located at the upper end of rotating block 2 1008; the top surface of horizontal rod 101 is fixed to guide block 1001; the end face of vertical rod 2 104 facing the paper output end is fixed to bearing seat 4 1004; the end face of vertical rod 103 facing the paper output end is fixed to bearing seat 5 1101; the inner side of vertical rod 2 104 is rotatably connected to rotating block 3 1105.
[0034] In this invention, Figure 1 As can be seen, rotating block 2 1008 and rotating block 1 801 are rotatably connected to vertical rod 3 105 via rotating shaft, and rotating block 3 1105 is rotatably connected to the inner side of vertical rod 2 104 via rotating shaft; the support frame 1 adopts a mountain-shaped integrated molding structure, which significantly improves the rigidity and stability of the overall structure compared with the traditional split support; the setting of L-shaped support rod 12 accurately positions the installation position of bearing seat 2 6, ensuring the parallelism between the paper pressure roller 5 and the paper guide roller 2, ensuring that the pressure force of the two on the paper is uniform, and preventing the paper from running off-center during feeding.
[0035] like Figure 1 and 3 As shown, the abutment member 13 includes a cylinder 1301, a bearing 1302, and a bearing 1303; the cylinder 1301 is a hollow structure with open ends; the cylinder 1301 is located between the bearing 1302 and the bearing 1303, and its two ends are integrally connected to the annular ends of the inner rings of the bearing 1302 and the bearing 1303, respectively; the inner diameter of the cylinder 1301 is larger than the inner diameter of the inner rings of the bearing 1302 and the bearing 1303, and its outer diameter is smaller than that of the bearing 1302. 2. The outer diameter of the inner ring of bearing 1302 and bearing 21303 is equal; the inner rings of bearing 1302 and bearing 21303 are integrally formed with the two ends of replacement roller 7 and paper roll 9, respectively; the middle position of cylinder 1301 at both ends of replacement roller 7 is located between swing arm 28011 and elastic component 808; the top of swing arm 31002 is located outside cylinder 1301; bearing 1302 at both ends of paper roll 9 is slidably connected to guide block 1001 through slide groove 210011.
[0036] In this invention, Figure 3The image shows the right side of replacement roller 7 and paper roll 9. Bearing 1302 is located inside bearing 2 1303, meaning the left side of replacement roller 7 and paper roll 9 is... Figure 3 The mirror image; the cylindrical 1301 facilitates the contact and movement of the roller body by the pressure roller mechanism 8 and the guide mechanism 10.
[0037] like Figure 3-4 As shown, the top surface of the sliding plate 8083 and the end face of the swing arm 8011 facing the crossbar between the upper support arm 8052 and the lower support arm 8053 are respectively provided with arc-shaped surfaces that are compatible with the cylinder 1301.
[0038] In this invention, the arc-shaped surfaces of the sliding plate 8083 and the second swing arm 8011 are adapted to the outer arc surface of the first cylinder 1301, which increases the contact area with the first cylinder 1301 and makes the contact force distribution more uniform.
[0039] like Figure 1 and 5 As shown, a fourth rotating shaft 14 is integrally connected between the two rotating shafts 2 1003; a fifth rotating shaft 15 is integrally connected between the two rotating shafts 3 1102.
[0040] In this invention, since the two cylinders 3 1005 move synchronously and the two cylinders 4 1106 move synchronously, the four rotating shafts 14 and 5 rotating shafts 15 are set to improve the overall stability of the equipment.
[0041] like Figure 1 , Figure 3 and Figure 7 As shown, a baffle 16 is fixedly connected to the outer side of the vertical rod 103; an annular part 17 is integrally connected to the middle position of the outer ring of the bearing 1302; the sliding groove 10011 is in the shape of an inverted U; the annular part 17 is slidably connected to the guide block 1001 through the sliding groove at the lower end of the sliding groove 10011; the outer ring of the bearing 1302 is slidably connected to the guide block 1001 through the sliding groove at the upper end of the sliding groove 10011.
[0042] In this invention, the inverted convex groove 10011 cooperates with the annular part 17 and the outer ring of the bearing 1302 to further limit the axial movement of the paper roll 9; the baffle 16 can limit the movement of the swing arm 1002.
[0043] In this invention, it is particularly important to further explain the spatial relationships, such as... Figure 1 The paper output end faces the paper roll 9, with swing arm 805 in the middle, and swing arm 1002 and rotating rod 1103 located on either side of swing arm 805; Figure 8As shown, there is a certain space between the lower plate of connecting plate 804 and the inner bottom of U-shaped part 803, so that when connecting plate 804 moves in an arc around the hinge axis, it does not interfere with the inner bottom of U-shaped part 803, ensuring the arc movement distance of the swing arm 805 connected to the upper plate of connecting plate 804. U-shaped parts 8010, 1006, and 1108 are similar to U-shaped part 803 and will not be repeated. Based on the technical solution of this application, the individual motion trajectories and relationships of pressure roller mechanism 8, guide mechanism 10, and rotating mechanism 11 have been described in detail and will not be repeated. For the equipment as a whole, the linkage between cylinders is required. When the paper roll on the paper roll 9 reaches the preset requirement and the paper roll 9 needs to be replaced, cylinder 3 1005 is started first. During the process of moving the paper roll 9 to clamping plate 1104, the cylinder is started. The replacement roller 7 (809) contacts the guide roller 2 to wind paper, and the paper winding roller 9 breaks the paper, thus completing the paper replacement. Subsequently, the paper winding roller 9 has moved onto the clamping plate 1104. The cylinder 1 (802) is activated to allow the bearing 1302 on the replacement roller 7 to enter the slide groove 10011 and contact the guide block 1001. The cylinder 3 (1005) is activated to reset. At this time, the swing arm 3 (1002) contacts the cylinder 1301 on the replacement roller 7. Due to the spatial relationship, the swing arm 3 (1002) and the swing arm 2 (8011) do not interfere with each other. The swing arm 3 (1002) is located outside the swing arm 2 (8011). The cylinder 2 (809) is activated to reset. As the amount of paper on the replacement roller 7 increases and the thickness increases to a certain amount, the cylinder 1301 disengages from the placement groove 1 (8051). The cylinder 1 (802) is activated to reset. Then, a crane is used to place the new replacement roller 7 into the placement groove 1 (8051). This process is repeated to achieve automatic replacement of the paper winding roller.
