Description

Technical Field

[0001] This utility model relates to the technical field of raw material tape equipment, specifically to a slitting and rewinding integrated machine. Background Technology

[0002] PTFE tape is a commonly used auxiliary material in pipe installation. It is used at pipe joints to enhance the airtightness of the pipe joints.

[0003] Raw material tape is typically wound around a core for ease of use. During the winding process, the core is usually placed on a take-up shaft and then temporarily fixed to it. The winding of the raw material tape is achieved by rotating the take-up shaft. Traditional take-up shafts have complex mechanisms to restrict the sliding of the core, which affects the loading and unloading efficiency of the core and makes loading and unloading inconvenient. If the core is not securely fixed, it is easy for the core to move along its axis as the take-up shaft rotates, resulting in defective products and affecting the winding of the raw material tape, thus leading to relatively low production efficiency.

[0004] In view of this, the applicant has conducted in-depth research on the above-mentioned issues, which led to this case. Utility Model Content

[0012] As an improvement of this utility model, the rewinding mechanism further includes an upper core assembly. The upper core assembly includes a horizontally arranged base plate, which is fixedly mounted on the base by a bracket.

It is easy to load and unload and has relatively high production efficiency.

[0053] The utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0054] The terms "first", "second", "third", "fourth", "fifth", "sixth", "seventh", etc., used in the specification, claims and drawings of this utility model are used to distinguish different objects, rather than to describe a specific order.

[0055] like Figures 1-4 As shown, this embodiment provides a slitting and rewinding integrated machine, including a base 10, which is horizontally arranged. A slitting mechanism 20 and a rewinding mechanism 21 are provided on the base 10. The slitting mechanism 20 and the rewinding mechanism 21 are arranged sequentially along the length of the base 10. By setting the slitting mechanism 20 and the rewinding mechanism 21 together, there is no need to perform slitting and rewinding operations independently, realizing the assembly line operation of slitting and rewinding, which greatly improves production efficiency.

[0056] The rewinding mechanism 21 includes a first frame 22 fixedly connected to the base 10, an indexing plate 23 rotatably connected to the first frame 22, and a first drive mechanism for driving the indexing plate 23 to rotate. The first drive mechanism is the same as the drive mechanism of conventional raw material tape, and will not be described in detail here. The indexing plate 23 is provided with three take-up shafts 24 evenly distributed around the axis of the indexing plate 23. Next to the indexing plate 23, there are upper core station, winding station and unwinding station evenly arranged clockwise or counterclockwise from the center of the indexing plate 23. The specific position of the indexing plate 23 when the take-up shafts 24 correspond to each station needs to be arranged according to the actual situation. The indexing plate 23 rotates one-third of a turn each time. In this way, when the indexing plate 23 stops rotating, the three take-up shafts 24 correspond to the upper core station, winding station and unwinding station respectively.

[0057] Each take-up shaft 24 has a receiving chamber 25. Within the same take-up shaft 24, the receiving chamber 25 is arranged along the axial direction of the take-up shaft 24. A friction wheel for driving the take-up shaft 24 to rotate is fixedly installed on the outer peripheral wall of the take-up shaft 24. A limiting ring 26 arranged coaxially with the take-up shaft 24 is provided on the outer peripheral wall of the take-up shaft 24. A guide hole 27 communicating with the receiving chamber 25 is opened on the outer peripheral wall of the take-up shaft 24. The guide hole 27 is arranged along the axial direction of the take-up shaft 24 and is away from the indexing plate 23 relative to the limiting ring 26. A tensioning block 28 is slidably connected in the guide hole 27. One side of the tensioning block 28 passes through the guide hole 27 and is located inside the receiving chamber 25, while the other side of the tensioning block 28 exits the guide hole 27 and is located outside the receiving chamber 25. A first frame 22 is provided with a piston rod arranged along the axial direction of the take-up shaft 24. A cylinder 29 is slidably connected to a pull rod 30 within a receiving chamber 25. One end of the pull rod 30 is located inside the receiving chamber 25, and the other end is located outside the receiving chamber 25. A limiting part is provided at the end of the pull rod 30 located outside the receiving chamber 25. A compression spring is sleeved on the pull rod 30. One end of the compression spring abuts against the limiting part, and the other end of the compression spring abuts against the end face of the take-up shaft 24 near the limiting part. A spring plate 31 is provided inside the receiving chamber 25 and arranged along the axial direction of the take-up shaft 24. One end of the spring plate 31 is fixedly connected to the end of the pull rod 30 located inside the receiving chamber 25, and the other end of the spring plate 31 is fixedly connected to a tension block 28. The end of the tension block 28 away from the indexing plate 23 is arranged gradually from one side inside the receiving chamber 25 to the corresponding other side towards the indexing plate 23.

[0058] A take-up drive mechanism for driving the friction wheel to rotate is provided on the first frame 22 at a position corresponding to the take-up station. The take-up drive mechanism includes a mounting roller fixedly connected to the first frame 22, a mounting plate rotatably connected to the mounting roller and arranged parallel to the plane of the first frame 22, a limiting plate fixedly connected to the first frame 22, a drive motor fixedly mounted on the mounting plate, and a drive wheel driven by the drive motor. The specific transmission connection between the motor and the drive wheel can be a conventional method. A friction ring is fixedly installed around the circumference of the drive wheel. When the take-up shaft 24 is not located at the position corresponding to the take-up station, the mounting plate... The lower end face abuts against the upper end face of the limiting plate. When the take-up shaft 24 rotates to the position corresponding to the winding station, the friction ring and the friction wheel abut against each other. The friction wheel and the friction ring can be driven by natural contact. The structure is simple and the efficiency is high. Three first cylinders 29 are set on the first frame 22. Each first cylinder 29 is arranged in a corresponding manner to the upper core station, the winding station, and the unwinding station. When the take-up shaft 24 rotates to the position corresponding to the winding station, the pull rod 30 in the take-up shaft 24 and the piston rod of the first cylinder 29 corresponding to the winding station are on the same straight line. In use, the piston rod of the first cylinder 29 extends to push the pull rod 30. The movement of the pull rod 30 causes the tension block 28 to move. During the movement of the tension block 28, the end of the tension block 28 away from the indexing plate 23 and the side wall of the guide hole 27 away from the indexing plate 23 abut against each other and can move relative to each other. The tension block 28 continues to move, pushing the spring plate 31 to move towards the axis of the take-up shaft 24 until the tension block 28 retracts into the receiving chamber 25. The piston rod of the first cylinder 29 retracts, and under the action of the compression spring, it drives the pull rod 30 to pull out. The pull rod 30 pulls out and causes the tension block 28 to retract. Under the action of the spring plate 31, the tension block 28 extends out of the guide hole 27. The tension block 28 continues to retract until it abuts against the guide hole 24. In this embodiment, there are two tensioning blocks 28 on the inner wall of the guide hole 27, and two corresponding guide holes 27 in the same take-up shaft 24. The two tensioning blocks 28 are slidably connected one-to-one in the two guide holes 27. The line connecting the two tensioning blocks 28 is located in the radial direction of the take-up shaft 24. When in use, the core is put into the take-up shaft 24. By pulling out the pull rod 30, the tensioning block 28 extends out of the guide hole 27 and abuts against the core to achieve the positioning of the core. By pushing the pull rod 30, the tensioning block 28 is completely retracted into the accommodating chamber 25. Then the core is unloaded from the take-up shaft 24. The loading and unloading is convenient and the production efficiency is relatively high.

[0059] The slitting mechanism 20 includes a second frame 32, which is fixedly mounted on the base 10. The second frame 32 is equipped with a first guide roller group and a second guide roller group for guiding the raw material strip. The second frame also has a first guide roller drive mechanism for synchronously driving the guide rollers in the first guide roller group 33 and a second guide roller drive mechanism for synchronously driving the guide rollers in the second guide roller group. The specific transmission connection structure between the first guide roller group 33 and the first guide roller drive mechanism, as well as the specific connection structure between the second guide roller group and the second guide roller drive mechanism, are conventional structures and will not be described in detail here. The first guide roller group 33 and the second guide roller group are arranged in a vertical square shape. The first guide roller group 33 is located above the second guide roller group. Both the first guide roller group 33 and the second guide roller group include horizontally arranged first and second guide rollers. The first and second guide rollers are arranged parallel to the take-up shaft 24 and are located on the same horizontal plane. The second guide roller is closer to the rewinding mechanism than the first guide roller. The second frame 32 is provided with a vertically arranged guide rail 34. The guide rail 34 is slidably connected to a slider 35. The slider 35 is fixedly connected to a first fixing plate 36. The second frame 32 is also provided with a... In this embodiment, the second driving mechanism that drives the slider 35 to move along the guide rail 34 is a sliding cylinder. The first fixed plate 36 is rotatably connected to a mounting rod 37 arranged along the axial direction of the receiving shaft 24. The mounting rod 37 is located above the first guide roller group 33, and its horizontal projection is located between the first and second guide rollers. The mounting rod 37 is fitted with multiple spacers (not shown in the figure). A first blade 38 is fitted onto the mounting rod 37 between two adjacent spacers. Limiting members (not shown in the figure) are provided at both ends of the mounting rod 37 to restrict the axial movement of the spacers. As shown in the diagram, a third drive mechanism for driving the mounting rod 37 to rotate is provided on the first fixed plate 36. In this embodiment, the second drive mechanism is a motor. The specific transmission connection structure between the mounting rod 37 and the motor can be a conventional structure, which will not be described in detail here. By providing a slitting mechanism 20, the raw material strip can be cut into multiple strips with smaller widths before entering the rewinding mechanism 21. In this embodiment, the first blade 38 is sandwiched between spacers. The distance between the two first blades 38 can be adjusted by adjusting the size of the spacers, thereby adjusting the slitting width of the raw material strip.

[0060] The slitting mechanism 20 also includes a feeding assembly, which is located on the base 10. The feeding assembly is located on the side of the second frame 32 away from the first frame 22. The feeding assembly has the same structure as the conventional raw material belt feeding assembly, and will not be described in detail here.

[0061] A first guide roller 41 is rotatably connected to the first frame 22, and a second guide roller 42 is rotatably connected to the second frame 32. The first guide roller 41 and the second guide roller 42 are located on the same horizontal plane. By setting the first guide roller 41 and the second guide roller 42, it is convenient to guide the raw material tape to the rewinding mechanism 21.

[0062] A tension swing arm assembly is provided on the second frame 32. The tension swing arm assembly includes a first fixed roller 71 fixedly connected to the second frame 32 and arranged parallel to the take-up shaft 24; a swing arm 72 rotatably connected to the first fixed roller 71 at one end and arranged parallel to the plane of the second frame 32; a second fixed roller 73 fixedly connected to the other end of the swing arm 72 and arranged parallel to the first fixed roller 71; a drive pulley (not shown in the figure) fixedly connected to the end of the swing arm 72 connected to the first fixed roller 71 and arranged coaxially with the first fixed roller 71; a rotating roller 74 rotatably connected to the second frame 32; a driven pulley 75 fixedly connected to one end of the rotating roller 74 and located on the same plane as the drive pulley; and a belt 75 wound around the drive pulley and the driven pulley 75. 6. A potentiometer (not shown in the figure) and a controller electrically connected to the other end of the rotating roller 74 are connected via a coupling. It should be noted that the controller is a conventional PLC controller, which has the conventional function of analyzing and comparing input signals to output corresponding control signals. The potentiometer is a conventional potentiometer, which can be purchased directly from the market and will not be described in detail here. The potentiometer and the controller are electrically connected. The first guide roller drive mechanism and the second guide roller drive mechanism are respectively electrically connected to the controller. In this embodiment, the first fixed roller 71 is located between the second guide roller group and the second guide roller 42. There are two swing arms 72, and the second fixed roller 73 is fixedly connected between the two swing arms 72. Before use, the raw material belt coming out of the guide roller group 33... First, the material passes over the top of the first fixed roller 71, then under the second fixed roller 73, and then over the top of the second guide roller 42. The speeds of the first guide roller group 33 and the second guide roller group are the same. When the take-up speed of the take-up shaft 24 at the winding station is greater than the speed of the first guide roller group 33, the swing arm 72 swings upward under the tension of the raw material belt. The swing arm 72 drives the drive pulley to rotate, which in turn drives the driven pulley 75 to rotate. The driven pulley 75 then drives the rotating roller 74 to rotate. At this time, the potentiometer detects the voltage change signal and transmits it to the controller. The controller automatically adjusts the first guide roller drive mechanism and the second guide roller drive mechanism according to the received voltage signal until the take-up speed of the take-up shaft 24 at the winding station is equal to the speed of the first guide roller group 33. When the speed of the first guide roller group 33 is consistent, the swing arm 72 returns to its initial position. When the take-up speed of the take-up shaft 24 at the winding station is less than the speed of the first guide roller group 33, the swing arm 72 swings downward under the tension of the raw material belt. The swing arm 72 drives the drive pulley to rotate, which in turn drives the driven pulley 75 to rotate. The driven pulley 75 then drives the rotating roller 74 to rotate. At this time, the potentiometer detects the voltage change signal and transmits it to the controller. The controller automatically adjusts the first guide roller drive mechanism and the second guide roller drive mechanism according to the received voltage signal until the take-up speed of the take-up shaft 24 at the winding station is consistent with the speed of the first guide roller group 33. The swing arm 72 then returns to its initial position. This is achieved by setting a tension swing arm assembly.Maintaining a constant tension in the raw material tape ensures a more stable winding effect.

[0063] The rewinding mechanism 21 also includes a humidification assembly, which includes a second fixing plate 43, a first roller 44, a second roller 45, and a water tank 46. The second fixing plate 43 is fixedly mounted on the first frame 22 and is located between the first guide roller 41 and the indexing plate 23. The plane of the second fixing plate 43 is parallel to the plane of the first frame 22. The first roller 44, the second roller 45, and the water tank 46 are all horizontally arranged and parallel to the take-up shaft 24. All water troughs 46 are fixedly mounted on the second fixed plate 43. The first roller 44 is located above the water trough 46. An eccentric shaft 47 is rotatably connected to the side wall of the water trough 46 along its length. Specifically, the length direction of the water trough 46 is the same as the axial direction of the receiving shaft 24. The eccentric shaft 47 includes an eccentric shaft section and two drive shaft sections. The two drive shaft sections are fixedly connected or integrally connected to both ends of the eccentric shaft section. The second roller 45 is fixedly sleeved on the eccentric shaft section. The side wall of the water trough 46 is provided with a mechanism for driving the eccentric shaft 46. The rotating cylinder 48 drives the spindle 47 to rotate. The specific transmission connection structure between the rotating cylinder 48 and the eccentric shaft 47 can be a conventional structure, which will not be detailed here. Before use, water is added to the water tank 26. During use, the rotating cylinder 48 drives the eccentric shaft 47 to rotate. When the eccentric shaft 47 rotates, it drives the second roller 45 to rotate. When the second roller 45 is in the lowest position, the raw material belt passing through the first guide roller 41 is disengaged from the second roller 45. The second roller 45 is immersed in water. It should be noted that the second... Roller 45 is completely submerged in water. When the second roller 45 is at its highest position, the raw material strip that has passed through the first guide roller 41 comes into contact with the second roller 45 and is humidified. By setting up a humidification component, the head and tail sections of the raw material strip are humidified separately. Humidifying the head section of the raw material strip can make it better adhere to the core, prevent the raw material strip from slipping relative to the core, and ensure stable winding. Humidifying the tail section of the raw material strip can make the tail section of each roll of material strip better wound up, prevent the material strip from loosening, and make the winding effect more neat and beautiful.
