Description

Technical Field

[0001] This utility model relates to the field of ceramic fiber manufacturing technology, specifically a ceramic fiber liner calendering device. Background Technology

[0002] Ceramic fiber is a fibrous, lightweight refractory material with advantages such as light weight, high temperature resistance, good thermal stability, low thermal conductivity, low specific heat, and resistance to mechanical vibration. Therefore, it has been widely used in industries such as machinery, metallurgy, chemical industry, petroleum, ceramics, glass, and electronics.

[0003] Chinese utility model patent CN112439790A, published on March 5, 2021, discloses a calendering roller and calendering device, including a main body. Both the front and rear surfaces of the main body are provided with grooves, and sliders are slidably connected inside the grooves. There are three sets of grooves: one set has a first connecting post, one set has a second connecting post, and the other set has a third connecting post. This invention uses the first, second, and third connecting posts to mount three sets of extrusion rollers. Simultaneously, the rotation of the stud, through the interaction of the positive, negative, and internal threads, causes the sliders to move relative to the two sets of first, second, and third connecting posts, adjusting the distance between the extrusion rollers. This reduces the force on each set of extrusion rollers, preventing deformation due to stress and indirectly improving the calendering quality. It also adapts to copper plates of different thicknesses.

[0004] However, the above-mentioned disclosed solutions have the following shortcomings: the existing rolling equipment is for rolling metal materials, but it is not suitable for rolling ceramic fibers, which will cause deformation of the ceramic fiber liner, requiring further processing and shaping, resulting in an additional process step and thus reducing the overall efficiency. Utility Model Content

[0005] The purpose of this invention is to solve the technical problem that the existing rolling device is used to roll metal materials, but it is not suitable for rolling ceramic fibers, which will cause the ceramic fiber liner to deform, requiring further processing and reshaping, resulting in an additional process step and a reduction in overall efficiency. The invention provides a ceramic fiber liner rolling device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution;

[0008] Furthermore, the rotating unit includes a motor fixed to a fixed plate; a gear is fixedly connected to the output shaft of the motor; a toothed groove is meshed and connected to the gear; the toothed groove is formed on the surface of the movable plate; a stepped shaft is rotatably inserted into the movable plate through an opening; a second fastener is inserted into the stepped shaft through an opening; the second fastener is threadedly connected to the intermediate block.

[0009] Furthermore, the length of the sleeve is less than the diameter of the limiting groove.

[0010] The ceramic fiber liner calendering device provided by this utility model has the following beneficial effects:

[0011] 1. This utility model uses a hydraulic push rod to push the rotating unit, movable plate and central shaft down, so that the central shaft contacts the inner surface of the limiting groove to calender the ceramic fiber liner in the calender groove and rotates it to calender, so that the space in the calender groove is filled, so that the final size of the calendered ceramic fiber liner is consistent, and a large number of ceramic fiber liners can be calendered at one time.

[0012] 2. This utility model uses a motor to drive the gears to rotate the toothed groove and the movable plate, thereby rotating the sleeve to perform a calendering operation on the ceramic fiber liner in the calendering groove, so that the ceramic fiber liner can be calendered to fill the calendering groove and calender the ceramic fiber liner to the set three-dimensional dimensions.

[0022] Please see Figure 1-4As shown, a ceramic fiber liner calendering device includes a track plate 4 fixed to a supporting plane; a calendering die plate 1 is slidably connected inside the track plate 4, allowing the calendering die plate 1 to move left and right within the track plate 4; the calendering die plate 1 has a limiting groove 2; multiple calendering grooves 3 are provided in the limiting groove 2, allowing two people to cooperate in placing the ceramic fiber liner to be calendered into the calendering grooves 3 on both sides and removing the calendered ceramic fiber liner; a suspension 6 is fixedly connected to the track plate 4; a hydraulic push rod 9 is fixedly connected to the suspension 6; a middle block 10 is fixedly connected to the movable end of the hydraulic push rod 9; a first [unclear - possibly a device or component] is inserted into the middle block 10 through an opening. Fastener 12; a fixing plate 11 is sleeved on the first fastener 12; a rotating unit is provided on the fixing plate 11; a movable plate 15 is sleeved on the rotating unit; a central shaft 16 is inserted into the lower end of the movable plate 15; a sleeve 17 is sleeved on the central shaft 16. The rotating unit, movable plate 15 and central shaft 16 are pushed down by the hydraulic push rod 9, so that the central shaft 16 contacts the inner surface of the limiting groove 2 and the ceramic fiber liner in the calendering groove 3 is rotated and calendered, so that the space in the calendering groove 3 is filled, so that the final size of the calendered ceramic fiber liner is consistent, and a large number of ceramic fiber liners can be calendered at one time.

[0023] The rotating unit includes a motor 20 fixed on a fixed plate 11; a gear 19 is fixedly connected to the output shaft of the motor 20; a toothed groove 18 is meshed and connected to the gear 19; the toothed groove 18 is formed on the upper surface of the movable plate 15; a stepped shaft 14 is rotatably inserted into the movable plate 15; a second fastener 13 is inserted into the stepped shaft 14; the second fastener 13 is threaded onto the intermediate block 10. When the motor 20 is powered on, it drives the gear 19 to rotate the toothed groove 18 and the movable plate 15, thereby rotating the sleeve 17 to perform a calendering operation on the ceramic fiber liner in the calendering groove 3, so that the ceramic fiber liner can be calendered and filled into the calendering groove 3, and the ceramic fiber liner is calendered to the set three-dimensional dimensions.

[0024] The length of the sleeve 17 is less than the diameter of the limiting groove 2, so that the sleeve 17 can rotate around the limiting groove 2 to perform calendering operation on the ceramic fiber liner, and multiple ceramic fiber liners in the limiting groove 2 can be calendered at one time.

[0025] The sleeve 17 is made of stainless steel, which prevents it from reacting with the ceramic fiber liner when in contact with it, allowing for long-term and stable calendering of the ceramic fiber liner.

[0026] An oil storage tank 7 is provided on the calendering die plate 1; the oil storage tank 7 is connected to the track plate 4 and has a permeation hole 8. By pouring lubricating oil into the oil storage tank 7, the lubricating oil enters the contact surface between the calendering die plate 1 and the track plate 4 through the permeation hole 8 for lubrication, thereby reducing friction and making the left and right movement resistance of the calendering die plate 1 small, thereby reducing the labor intensity of the operator.

[0027] Handles 5 are symmetrically fixed to both sides of the calendering die plate 1. By using the handles 5 on both sides of the calendering die plate 1, the calendering die plate 1 can be pushed and pulled, so that it can move left and right around the center of the sleeve 17. This allows two people to work together on both sides of the calendering die plate 1 to work on the upper and lower ceramic fiber pads and the calendered ceramic fiber pads, thereby increasing the calendering efficiency of the ceramic fiber pads.
