Description

Technical Field

[0001] The utility model relates to the technical field of textile machinery, in particular to a low thermal deformation cover plate frame. Background Art

[0002] The flat plate frame is a carrier for the flat plate carding machine frame to load the flat plate clothing. The flat plate clothing cooperates with the relative cylinder needle teeth to loosen the fiber raw materials, remove impurities, and make the fibers parallel and single. The closest distance between the flat plate clothing needle tip and the cylinder clothing needle tip is called the gauge. When the fiber is combed, the flat plate frame will deform and cause the gauge to decrease. With the increase in the output and width of the carding machine, the reduction in the gauge increases significantly, so that the needle tips collide with each other, causing damage to the equipment.

[0003] There are two main sources of skeleton deformation. The first is the combing force during the combing process. The second is the heat transfer during the combing process, which causes the internal and external temperature gradient of the skeleton, and under the existing carding machine assembly structure, it produces a bending towards the cylinder needle clothing.

[0004] This degree of bending increases significantly with the increase of internal and external temperature gradients and skeleton length. On traditional 1m wide carding machines, this deformation is not obvious. However, in carding machines with a width of more than 1.28m, this deformation caused by the temperature gradient is particularly obvious. At the same time, in order to be able to extract heat well from the carding machine, the existing cover plate skeleton generally uses aluminum profiles with high thermal conductivity. This means that the aluminum skeleton must use a higher profile height than cast iron material to resist the deformation caused by the combing force. When the skeleton width increases, since the skeleton itself only forms fulcrums on both sides, the aluminum profile skeleton must use a higher height than the general carding machine to resist this deformation. This further exacerbates the temperature gradient difference inside and outside the skeleton, resulting in more serious thermal deformation of the skeleton.

[0005] Some manufacturers use a reserved concave design of 0.10-0.30mm on the plane of the cover frame to offset the deformation of the frame. However, in actual processing, this processing is difficult and can easily cause different degrees of concave in different frames, thereby worsening the combing effect.

[0006] In the document CN202122297899, an aluminum alloy movable cover plate with anti-thermal deformation function is disclosed, including an aluminum alloy cover plate frame, a steel card clothing edge clamp and a steel card clothing, the steel card clothing is fixed to the lower end surface of the aluminum alloy cover plate frame by the steel card clothing edge clamp, and a steel isothermal balance part is provided in the aluminum alloy cover plate frame, and the steel isothermal balance part is contact-connected to the aluminum alloy cover plate frame. On the one hand, this structure will increase the total weight of the frame, and because the straightness of the steel circular structure itself is difficult to control, there is a matching gap between the two, the installation is difficult, and the manufacturing cost is also relatively high. The heat insulation strip is located at the center of the cover plate frame, and the heat dissipation of the side cover plate frame cannot be curbed.

[0007] Therefore, a new technical solution is needed to solve the above technical problems. Summary of the invention

[0008] In order to solve the above problems, the utility model discloses a low thermal deformation cover plate frame with a heat insulation strip on the side of the cover plate frame body. While curbing heat dissipation and preventing deformation, it can also reduce the cost of equipment improvement and continue to use the previous production line.

[0009] The technical solution of the utility model is: a low thermal deformation cover plate frame, including a cover plate frame body, the cover plate frame body is provided with a thermal insulation strip receiving groove, the thermal insulation strip receiving groove is located on both sides of the upper outer side of the cover plate frame body, the thermal insulation strip receiving groove is a groove that is concave downward on the surface of the cover plate frame body, a thermal insulation strip is provided in the groove, and the thermal insulation strip and the groove are connected by snapping, bonding or snap-fitting.

[0010] By adopting the above technical solution, an insulation strip is added to the side of the cover frame body to prevent heat from being lost from this area to the air, thereby reducing the temperature gradient between the cover frame and the upper outer side and the bottommost plane, thereby reducing the deformation of the frame caused by temperature.

[0012] By adopting the above technical solution, the insulation strip receiving groove has no essential impact on the overall basic structure of the cover frame. When the cover frame is produced, the previous equipment and process can still be used for production, and there is no need to improve the previous device to adapt to new production needs.

[0013] Preferably, when the insulation strip receiving groove is a wedge-shaped groove, the side close to the cover plate frame body is longer than the outer side, that is, it is a trapezoidal shape with a short outer side and a long inner side.

[0014] By adopting the above technical solution, when the thermal insulation strip is installed in the thermal insulation strip receiving groove, the thermal insulation strip can be clamped and prevented from escaping.

[0015] Preferably, the heat-insulating strips are located in the heat-insulating strip receiving grooves, pass through the entire side of the cover plate frame body, are independent of each other, and are embedded or semi-embedded in the cover plate frame body.

[0016] By adopting the above technical solution, the heat insulation strip is located on the side of the cover frame and has the same length as the cover frame. In this way, it can be ensured that the entire cover frame can prevent heat from being lost from this area to the air.

[0018] By adopting the above technical solution, the heat can be contained by using any shape of heat insulation strips symmetrically or asymmetrically on both sides of the cover frame.

[0019] Preferably, the shape of the thermal insulation strip is regular or irregular.

[0020] By adopting the above technical solution, the shape of the heat insulation strip only needs to be able to be snapped into the heat insulation strip receiving groove, or be compatible with the heat insulation strip receiving groove.

[0021] Preferably, the shape of the thermal insulation strip is rectangular, trapezoidal or biconvex.

[0022] By adopting the above technical solution, the shape of the heat insulation strip can be regular or irregular as long as it is compatible with the heat insulation strip receiving groove.

[0023] Preferably, the material of the thermal insulation strip is a non-metallic material.
