Description

Technical Field

[0001] This utility model relates to the field of plastic product processing technology, and more specifically, to an extrusion and calendering device for air conditioner plastic wrapping tape. Background Technology

[0002] Air conditioning plastic wrapping tape (also known as air conditioning cable ties or wrapping tape) is a functional plastic product specifically designed for the protection and bundling of air conditioning ducts. The current production steps for air conditioning plastic wrapping tape are as follows: raw material preparation, melt extrusion, cooling and molding, calendering and stretching, surface treatment, cutting, and winding.

[0003] Currently, during the calendering process of air conditioner plastic wrapping tape, the calendering method mainly involves extrusion through multiple sets of calendering rollers. The thickness adjustment of the air conditioner plastic wrapping tape needs to be achieved by adjusting the spacing between the calendering rollers. However, the current multiple sets of calendering rollers need to have their spacing adjusted independently, which is time-consuming and causes fluctuations in lateral thickness due to poor synchronization.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an extrusion and calendering device for air conditioning plastic wrapping tape, in order to achieve a more practical purpose. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the problems of long adjustment time and poor synchronization in the extrusion and calendering of air conditioner plastic wrapping tape.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an extrusion and calendering device for air conditioner plastic wrapping tape, used for extrusion, cooling, and calendering in the production of air conditioner plastic wrapping tape, comprising a screw extruder body, a cooling tank, and a calendering device arranged sequentially from left to right. The extrusion end of the screw extruder body is provided with a flat die. The calendering device includes a frame, with a calendering roller rotatably connected to the inner side of the frame, and a servo motor fixedly connected to the outer side of the frame. The output shaft of the servo motor rotatably connects to the shaft end of the calendering roller rotat. An adjustment structure is provided on the frame, and a second calendering roller and a third calendering roller are respectively arranged on the adjustment structure. The second and third calendering rollers are located on both sides of the first calendering roller, and a transmission assembly is provided between the second, third, and first calendering rollers.

[0007] In a preferred embodiment, a pressure roller is rotatably connected inside the cooling tank.

[0008] In a preferred embodiment, a pair of transfer rollers are rotatably connected to the inner side of the frame, and the pair of transfer rollers are located on both sides of the calendering roller.

[0009] In a preferred embodiment, a pair of fixed frames are fixedly connected to the inner side of the frame. The adjustable structure includes a second servo motor, which is fixedly connected to the side of one of the fixed frames. A bidirectional lead screw is rotatably connected between the pair of fixed frames. The output shaft of the second servo motor passes through the fixed frame and is fixedly connected to one end of the bidirectional lead screw. A first movable frame and a second movable frame are respectively driven and connected to the bidirectional lead screw. A first slide block is fixedly connected to both ends of the first movable frame, and a second slide block is fixedly connected to both ends of the second movable frame. Both the first slide block and the second slide block are slidably connected to the frame.

[0010] In a preferred embodiment, the second calendering roll is rotatably connected between the first slide and the first movable frame, and the third calendering roll is rotatably connected between the second slide and the second movable frame.

[0011] In a preferred embodiment, the transmission assembly includes a driving transmission component and a driven transmission component. The driving transmission component includes a pair of support plates, both of which are fixedly connected to the outside of the frame. A spline cylinder is rotatably connected between the pair of support plates. A gear transmission mechanism is provided between the outer surface of the spline cylinder and the shaft end of the calendering roll.

[0012] In a preferred embodiment, the driven transmission assembly includes a spline shaft, which is slidably connected to the first spline cylinder.

A gear transmission mechanism is provided between the outer surface of the second spline cylinder and the shaft end of the second calendering roll. A fixing plate is fixedly connected to one of the slides. The second spline cylinder is rotatably connected to the fixing plate. A fixing plate is fixedly connected to one of the slides. One end of the empty section of the spline shaft is rotatably connected to the fixing plate.

[0013] In a preferred embodiment, a laser rangefinder sensor is mounted on one of the slides, and a laser emitting plate is fixedly connected to the outside of the frame, with the laser emitting plate located on one side of the laser rangefinder sensor.

[0014] The technical effects and advantages of this utility model are as follows: 1.

This can accelerate the rapid adjustment of the calendering thickness of the air conditioning plastic wrapping tape. Furthermore, due to the setting of the transmission assembly, the rotational power of calendering roller two can be effectively used to link calendering roller two and calendering roller three to adaptively rotate. While ensuring the stretching quality of the air conditioning plastic wrapping tape, it can also meet the calendering synchronization and reduce the driving cost.

[0019] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0020] See also Figures 1-5 This utility model provides an extrusion and calendering device for air conditioner plastic wrapping tape, used for extrusion, cooling and calendering in the production of air conditioner plastic wrapping tape, including a screw extruder body 1, a cooling tank 2 and a calendering device arranged from left to right.

[0021] In this embodiment, a flat die head 3 is provided at the extrusion end of the screw extruder body 1.

[0022] The principle of the screw extruder body 1 is to achieve the plasticization, mixing and molding of solid materials through the pressure, shearing force and heating system generated by the screw rotation. Finally, the molten plastic can be extruded into a continuous strip material of a specific width through the flat die 3. The screw extruder body 1 is a key piece of equipment for plasticizing and extruding raw materials for air conditioning plastic wrapping tape. Since it is existing technology, it will not be described in detail here.

[0023] In this embodiment, a pressure roller 25 is rotatably connected inside the cooling tank 2.

[0024] Cooling tank 2 can be filled with cooling water. The continuous strip material extruded through flat die 3 can pass under pressure roller 25 to achieve guided cooling, so that the molecular structure forms crystals and improves the subsequent calendering and stretching effect.

[0025] In this embodiment: the calendering equipment includes a frame 4, a calendering roller 5 is rotatably connected to the inner side of the frame 4, and a servo motor 6 is fixedly connected to the outer side of the frame 4. The output shaft of the servo motor 6 is fixedly connected to the shaft end of the calendering roller 5.

[0026] Servo motor 6 can be used to drive calendering roller 5 to rotate, and the rotation of calendering roller 5 can provide tensile force for the extension of air conditioner plastic wrapping tape.

[0027] In this embodiment, a pair of transfer rollers 26 are rotatably connected to the inner side of the frame 4, and the pair of transfer rollers 26 are located on both sides of the calendering roller 5.

[0028] A pair of transfer rollers 26 are located at the beginning and end of the frame 4 respectively. The transfer rollers 26 can transfer and guide the air conditioner plastic wrapping tape for calendering.

[0029] In this embodiment: A distance adjustment structure is provided on the frame 4. A pair of fixed frames 7 are fixedly connected to the inner side of the frame 4. The distance adjustment structure includes a second servo motor 8. The second servo motor 8 is fixedly connected to the side of one of the fixed frames 7. A bidirectional lead screw 9 is rotatably connected between the pair of fixed frames 7. The output shaft of the second servo motor 8 passes through the fixed frame 7 and is fixedly connected to one end of the bidirectional lead screw 9. A first movable frame 10 and a second movable frame 11 are respectively driven and connected to the bidirectional lead screw 9. A first slide block 101 is fixedly connected to both ends of the first movable frame 10. A second slide block 111 is fixedly connected to both ends of the second movable frame 11. The first slide block 101 and the second slide block 111 are slidably connected to the frame 4.

[0030] In this application, the frame 4 is provided with sliding grooves for sliding of slide block 101 and slide block 211. In use, the fixed frame 7 can stabilize the installation position of servo motor 28 and bidirectional lead screw 9. By starting the servo motor 28, the servo motor 28 can drive the bidirectional lead screw 9 to rotate. With slide block 101 and slide block 211 providing sliding guides for moving frame 10 and moving frame 211 respectively, moving frame 10 and moving frame 211 can move linearly closer or further away from each other on the bidirectional thread surface of the bidirectional lead screw 9.

[0031] In this embodiment: a second calendering roll 12 and a third calendering roll 13 are respectively provided on the adjusting structure. The second calendering roll 12 and the third calendering roll 13 are located on both sides of the first calendering roll 5. The second calendering roll 12 is rotatably connected between the first slide block 101 and the first moving frame 10, and the third calendering roll 13 is rotatably connected between the second slide block 111 and the second moving frame 11.

[0032] Since the moving frame 10 and the moving frame 21 can move linearly closer to or further away from each other on the bidirectional threaded surface of the bidirectional screw 9, the calendering roller 212 and the calendering roller 313 can synchronously move closer to or further away from the position of the calendering roller 15. This facilitates quick adjustment of the gap between the calendering roller 15 and the calendering roller 212, as well as between the calendering roller 15 and the calendering roller 313. This gap can meet the requirements of the calendering thickness of the air conditioner plastic wrapping tape.

[0033] In this embodiment: a transmission assembly is provided between calender roll 2 12, calender roll 3 13, and calender roll 5. The transmission assembly includes a driving transmission component and a driven transmission component. The driving transmission component includes a pair of support plates 14, both of which are fixedly connected to the outside of the frame 4. A spline cylinder 15 is rotatably connected between the pair of support plates 14. A gear transmission mechanism 16 is provided between the outer surface of the spline cylinder 15 and the shaft end of the calender roll 5. The driven transmission component includes a spline shaft 17, which is slidably connected inside the spline cylinder 15. A splined cylinder 18 is connected to the splined shaft 17 via a sliding key. A gear transmission mechanism 19 is provided between the outer surface of the splined cylinder 18 and the shaft end of the calendering roll 12. A fixing plate 20 is fixedly connected to one of the slides 101. The splined cylinder 18 is rotatably connected to the fixing plate 20. A fixing plate 21 is fixedly connected to one of the slides 111. One end of the empty shaft section of the splined shaft 17 is rotatably connected to the fixing plate 21. A gear transmission mechanism 22 is provided between one end of the splined shaft 17 and the shaft end of the calendering roll 13.

[0034] The gear transmission mechanisms in this application are all composed of a pair of meshing bevel gears. The support plate 14 can rotatably support the position of the spline cylinder 15, the fixing plate 20 can be used to rotatably support the position of the spline cylinder 18, and the fixing plate 21 can be used to rotatably support the position of the bevel gear in the gear transmission mechanism 22.

[0035] In use, the continuous strip material extruded by the flat die 3 is introduced into the cooling tank 2 by passing it under the pressure roller 25. Then, one end of the traction strip material is wound around one of the transfer rollers 26 from above, and then wound in a wavy line on the second calender roller 12, the first calender roller 5, the third calender roller 13 and the other transfer roller 26 in sequence. When the servo motor 6 drives the first calender roller 5 to rotate, the rotational force of the first calender roller 5 can be transmitted to the spline cylinder 15 through the gear transmission mechanism 16. The spline cylinder 15 can transmit the rotational force to the spline shaft 17. The gear transmission mechanisms 219 and 32 at both ends of the spline shaft 17 can transmit the rotational power to the second calender roller 12 and the third calender roller 13 respectively. When the first calender roller 5 rotates counterclockwise, the second calender roller 12 rotates clockwise and the third calender roller 13 rotates clockwise. In this way, the strip material can be squeezed and stretched in the gap between the calender rollers.

[0036] Because the spacing between calender roll 2 12 and calender roll 3 13 relative to calender roll 1 5 can be adjusted, when calender roll 2 12 and calender roll 3 13 move laterally, spline shaft 17 can slide within spline cylinder 1 15, and spline cylinder 2 18 can slide on spline shaft 17. In this way, the rotational power of calender roll 1 5 can synchronously drive calender roll 2 12 and calender roll 3 13 to achieve calendering rotation. This can ensure drive synchronization and reduce drive cost, thereby solving the technical problems of long calendering thickness adjustment time and poor synchronization in the extrusion calendering of air conditioner plastic wrapping tape.

[0037] In this embodiment: a laser rangefinder 23 is mounted on one of the slides 101, and a laser emitting plate 24 is fixedly connected to the outside of the frame 4. The laser emitting plate 24 is located on one side of the laser rangefinder 23.

[0038] The laser rangefinder 23 uses a ZLDS series laser sensor. The principle of the laser rangefinder 23 is that the laser diode emits a laser pulse at the target. After being reflected by the laser emitting plate 24, the laser is scattered in all directions, and some of the scattered light returns to the sensor receiver. In this application, the laser rangefinder 23 should be set on the axis of the second calender roll 12, while the laser emitting plate 24 should be set on the axis of the first calender roll 5. In this way, the laser rangefinder 23 can measure the axial distance between the first calender roll 5 and the second calender roll 12. Based on the standard diameter parameters of the calender rolls, the distance between the first calender roll 5 and the second calender roll 12 can be calculated. By calculating the calendering gap between the calender rolls, the accuracy of the calender roll gap adjustment can be improved.

[0039] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional known device such as a computer that is used for control, and the existing publicly available power connection technology will not be elaborated in the text.
