Description

Technical Field

[0001] This utility model relates to the field of raw material tape technology, and in particular to a calendering device for raw material tape production. Background Technology

[0002] PTFE tape is a commonly used auxiliary material in liquid pipeline installation, applied to pipe joints to enhance the sealing of the connections. PTFE tape is a novel and ideal sealing material. The stretching of PTFE tape refers to the process of applying pressure to polytetrafluoroethylene (PTFE) material using mechanical equipment, forcing it through rollers to stretch it into a thin strip with a certain thickness and width. However, the distance between existing rollers is fixed and cannot be adjusted, thus preventing the processing and production of PTFE tape of different thicknesses. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies where the distance between rollers is fixed and cannot be adjusted, thus preventing the processing of raw material strips of different thicknesses. This invention proposes a calendering device for raw material strip production.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] Design a calendering device for producing raw material strips, including a support base, a pressing roller rotatably connected to the support base via bearings, a first motor drivingly connected to the pressing roller, the first motor being mounted on the support base, two limiting grooves formed on the support base, support bars slidably disposed within the two limiting grooves, a support frame fixedly connected between the two support bars, and multiple support rollers rotatably connected to the support frame via bearings, the multiple support rollers having different diameters, and the support frame being moved by a moving mechanism.

[0006] Preferably, the moving mechanism includes a threaded rod, which is rotatably connected to the support base via a bearing, and the threaded rod is threaded through the support frame.

[0007] Preferably, the support base has an observation port.

[0008] Preferably, a rotating shaft is rotatably connected to the support base via a bearing, and a pulley is fixedly connected to the rotating shaft and the threaded rod, with a belt sleeved between the two pulleys.

[0009] Preferably, a plurality of second motors are fixedly connected to the support frame, and the plurality of second motors are respectively connected to the plurality of support rollers for transmission.

[0010] Preferably, a first bevel gear is fixedly connected to the rotating shaft, a second bevel gear meshes with the first bevel gear, a rotating column is fixedly connected to the second bevel gear, and the rotating column is rotatably connected to the support base through a bearing.

[0011] Preferably, a rotating block is fixedly connected to the rotating column.

[0012] The present invention proposes a calendering device for producing raw material strips. The advantages are as follows: by using a moving mechanism to move the support frame, the position of the support roller is adjusted, thereby adjusting the diameter of the support roller located directly below the pressing roller and adjusting the gap between the support roller and the pressing roller, so as to produce raw material strips of different thicknesses.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example 1: Refer to Figure 1-3 A calendering device for producing raw material strips includes a support base 1, a pressing roller 4 rotatably connected to the support base 1 via bearings, a first motor 2 drivenly connected to the pressing roller 4, the first motor 2 being mounted on the support base 1, two limiting grooves being provided on the support base 1, support bars 14 being slidably arranged in the two limiting grooves, and a support frame 6 being fixedly connected between the two support bars 14. When the support frame 6 moves, it will drive the support bars 14 to slide in the limiting grooves.

[0019] Multiple support rollers 3 are rotatably connected to the support frame 6 via bearings. When the raw material belt passes between the support rollers 3 and the pressing rollers 4, the initial thickness of the raw material belt is greater than the distance between the support rollers 3 and the pressing rollers 4, thus pressing the raw material. At the same time, the raw material belt has a certain temperature during the calendering process, which causes the raw material belt to extend when it is pressed.

[0020] The diameters of the multiple support rollers 3 are all different. The support frame 6 is moved by a moving mechanism. By moving the support frame 6 by the moving mechanism, the position of the support rollers 3 is adjusted, thereby adjusting the diameter of the support rollers 3 located directly below the pressing roller 4 and adjusting the gap between the support rollers 3 and the pressing roller 4, so as to produce raw material strips of different thicknesses.

[0021] The moving mechanism includes a threaded rod 8, which is rotatably connected to the support base 1 via a bearing. The threaded rod 8 passes through the support frame 6. By rotating the threaded rod 8, the support frame 6 will be moved.

[0022] The support base 1 is provided with an observation port 7. The observation port 7 is designed to allow for observation, and the support roller 3 is positioned directly below the pressing roller 4 during adjustment.

[0023] Example 2: Refer to Figure 1-3 As another preferred embodiment of this utility model, based on embodiment 1, a plurality of second motors 5 are fixedly connected to the support frame 6. The plurality of second motors 5 are respectively connected to a plurality of support rollers 3. The rotation direction of the second motors 5 is opposite to the rotation direction of the first motor 2, so that the rotation direction of the support rollers 3 and the pressing rollers 4 is opposite, which plays a role in conveying the raw material belt so that the raw material belt passes through the gap between the support rollers 3 and the pressing rollers 4.

[0024] At the same time, the speed of the second motor 5 is adjusted so that the linear velocity of the support roller 3 is equal to that of the pressing roller 4, ensuring uniform stress distribution and improving product quality.

[0025] Example 3: Reference Figure 1-3In another preferred embodiment of this utility model, based on embodiment 2, a rotating shaft 11 is rotatably connected to the support base 1 via a bearing. A pulley 9 is fixedly connected to the rotating shaft 11 and the threaded rod 8. A belt 10 is sleeved between the two pulleys 9. A first bevel gear 12 is fixedly connected to the rotating shaft 11. A second bevel gear 13 meshes with the first bevel gear 12. A rotating column 15 is fixedly connected to the second bevel gear 13. The rotating column 15 is rotatably connected to the support base 1 via a bearing. A rotating block is fixedly connected to the rotating column 15. By adopting the design of the rotating column 15, the second bevel gear 13 is driven to rotate, so that the second bevel gear 13 drives the first bevel gear 12 to rotate. Under the action of the pulley 9 and the belt 10, the threaded rod 8 is driven to rotate. Since the rotating column 15 is located directly below the observation port 7, it is convenient to observe and adjust at the same time during adjustment, which is beneficial to position the support roller 3 directly below the pressing roller 4.

[0026] During adjustment, rotating the rotating column 15 drives the second bevel gear 13 to rotate, which in turn drives the first bevel gear 12 to rotate. Under the transmission of the pulley 9 and the belt 10, the threaded rod 8 is driven to rotate, and the position of the support frame 6 on the threaded rod 8 is adjusted, thereby adjusting the diameter of the support roller 3 located directly below the pressing roller 4 and adjusting the gap between the support roller 3 and the pressing roller 4.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
