Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation strip processing equipment, in particular to a traction device for thermal insulation strip coding. Background Art

[0002] Thermal insulation strips are usually used to block the heat transfer path, thereby reducing energy loss and improving the insulation effect of buildings. Thermal insulation strips are often used between aluminum alloy steel materials of doors and windows. When preparing thermal insulation strips, granular rubber raw materials are used to be heated and formed by an extruder. In order to distinguish the production information of the thermal insulation strips produced, a coding device is usually used to spray the logo, model or production date and other product information at a specified distance on the surface of each thermal insulation strip (that is, one product information is sprayed at the same distance). In order to improve the efficiency of thermal insulation strip coding, multiple thermal insulation strips are generally laid side by side, and then a spray terminal is used to spray each thermal insulation strip in turn.

[0003] At present, a traction device is required to clamp and pull the thermal insulation strips before or after coding, so that the thermal insulation strips can move flat and stably, so as to facilitate coding on the surface of the thermal insulation strips. The traction device currently suitable for traction of thermal insulation strips is usually mainly composed of two upper and lower traction wheels. Multiple (for example, 100) thermal insulation strips are simultaneously passed through the two traction wheels for traction. However, due to the influence of the extrusion parameters of the extruder, there will be errors in the thickness of each batch of thermal insulation strips produced, and the surface roughness and flatness of the traction rollers will be different, which makes it difficult to press multiple thermal insulation strips during traction, so that some thermal insulation strips cannot be pulled. Therefore, we need to propose a traction device for thermal insulation strip coding to solve the above-mentioned problems. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-4The utility model provides a technical solution: a traction device for inkjet coding of heat insulation strips, comprising: a bracket 1, on which a lower traction roller 4 is installed; a top plate 3 located above the bracket 1, and the top plate 3 is connected to the upper surface of the bracket 1 through a plurality of support rods 2; a plurality of upper traction rollers 8 located below the top plate 3, and the plurality of upper traction rollers 8 are arranged side by side above the lower traction roller 4, and each of the upper traction rollers 8 is connected to the top plate 3 through a distance adjustment mechanism 7 for adjusting the vertical position of the upper traction roller 8; elastic support mechanisms 10 located at both ends of the upper traction roller 8, and the elastic support mechanisms 10 located at both ends of the upper traction roller 8 are respectively connected to the two ends of the distance adjustment mechanism 7;

[0026] Through the cooperation of a lower traction roller 4 and multiple upper traction rollers 8, the multiple upper traction rollers 8 can use a separate pressing method to press the multiple insulation strips on the lower traction roller 4 in different areas, so that the multiple insulation strips in each area can be pressed tightly, reducing the problem of loose pressing due to differences in insulation strip size and surface roughness and flatness of the traction rollers. For example, 100 insulation strips are pulled by the lower traction roller 4 at the same time, and each upper traction roller 8 presses 10 insulation strips accordingly, so that the 100 insulation strips are pressed separately in different areas, thereby increasing the pressing force of the traction roller 8 in each area. If 100 insulation strips are pressed by one upper traction roller 8 at the same time, the insulation strips in some areas may not be pressed tightly.

[0027] The distance adjustment mechanism 7 includes an adjusting screw 71, a driving member 72 for driving the adjusting screw 71 to rotate, and a support plate 11 located below the top plate 3. The adjusting screw 71 is threadedly connected to the top plate 3, and the driving member 72 is installed at the upper end of the adjusting screw 71. The lower end of the adjusting screw 71 passes through the top plate 3 and is rotatably connected to the middle of the support plate 11. The two ends of the support plate 11 are connected to the inner top of the top plate 3 through the telescopic rod 14. The adjusting screw 71 is driven to rotate by the driving member 72, so that the adjusting screw 71 drives the support plate 11 to move upward or downward by means of the threaded cooperation with the top plate 3, thereby driving the position of the upper traction roller 8 through the support plate 11 to adjust the distance between the upper traction roller 8 and the lower traction roller 4, so that it can be suitable for the processing of thermal insulation strips of different thicknesses, thereby improving the versatility of the device.

[0028] The driving member 72 includes an adjusting hand plate, which is fixed to the upper end of the adjusting screw 71, so that the adjusting screw 71 can be manually rotated by using the adjusting hand plate to individually adjust the position of each upper traction roller 8. The number of upper traction rollers 8 used is installed in accordance with actual production needs so that it can meet the use of different processing equipment.

[0029] Each of the elastic support mechanisms 10 includes a support block 103 for providing support force for the upper traction roller 8 and a T-shaped rod 101 slidably inserted on the support plate 11, the lower end of the T-shaped rod 101 passes through the support plate 11 and is fixed to the upper end of the support block 103, and the T-shaped rod 101 located between the support plate 11 and the support block 103 is sleeved with a spring 102 on the outside, and the support plate 11 is provided with a through hole 13 for the T-shaped rod 101 to pass through. The elasticity of the spring 102 is used to create a certain expansion and contraction space between the support block 103 and the support plate 11, so that the upper traction roller 8 can automatically make fine adjustments to the insulation strip under slight errors of the insulation strip, thereby increasing the clamping force between the upper traction roller 8 and the lower traction roller 4. The elastic force of the spring 102 is selected according to the actual production needs to meet the corresponding elastic coefficient of the spring 102 to ensure the clamping force between the upper traction roller 8 and the lower traction roller 4.

[0030] Connecting rods 12 are fixed at both ends of the upper traction roller 8, and one end of the connecting rod 12 is rotatably connected to the support block 103 via a bearing to facilitate supporting the upper traction roller 8. The upper traction roller 8 is an unpowered roller and can rotate with the movement of the insulation strip.

[0031] A rotating shaft is fixed at both ends of the lower traction roller 4, one end of the rotating shaft is fixed to the bracket 1 through a connecting piece 9, and a driving mechanism 5 for driving the lower traction roller 4 to rotate is connected to one of the rotating shafts, so that the lower traction roller 4 can be driven to rotate by the driving mechanism 5, so that the lower traction roller 4 is a power roller, which makes it easier for the thermal insulation strip to automatically pass through between the upper traction roller 8 and the lower traction roller 4, thereby performing traction and guiding.

[0032] The driving mechanism 5 includes a driving motor 51, a motor seat 52 and two transmission sprockets 54. A base plate 6 is fixed on the bracket 1, and the motor seat 52 is fixed on the base plate 6. The driving motor 51 is installed on the motor seat 52.
