Description

Technical Field

[0001] This utility model relates to the field of coating curing technology, and to a curing oven for curing glass coating liquid. Background Technology

[0002] In the field of glass deep processing, coating technology is the core process for improving the optical performance, weather resistance and functionality of glass. As a key post-processing step in the coating process, the curing of coating solution has extremely high requirements for the sealing of the curing environment, temperature stability and equipment operation reliability. Precise temperature control and a sealed space must be achieved through a curing oven to ensure that the coating solution forms a uniform film and avoid defects such as pinholes, peeling and uneven thickness.

[0003] The lifting of the gas hood of existing curing ovens mostly relies on the synchronous drive of four corner lead screws. However, due to manufacturing tolerances (such as lead screw length deviation and insufficient thread precision) and cumulative assembly errors (such as the offset of the lifting column installation angle), in actual operation, there is often a phenomenon of forced jamming where a single or part of the lead screws reach the lifting limit first. Due to the lack of an effective buffer compensation structure, the lead screw thread profile is prone to slippage and deformation due to shear stress concentration, which leads to the paralysis of the drive mechanism and high frequency of equipment downtime and maintenance.

The driving mechanism includes a mounting bracket disposed on the upper end of the oven body, a transmission module disposed on the upper end of the mounting bracket, and a lifting module disposed on the side end of the mounting bracket.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0014] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0015] The following describes the embodiments and appendices. Figures 1-5 The technical solution of this utility model will be further described below.

[0016] Example 1 A curing oven for curing glass coating solution includes: an oven body 1, an air hood 2, and a drive mechanism 3 disposed between the oven body 1 and the air hood 2. The drive mechanism 3 includes a mounting bracket 31 disposed on the upper end of the oven body 1, a transmission module 32 disposed on the upper end of the mounting bracket 31, and a lifting module 33 disposed on the side end of the mounting bracket 31. The lifting module 33 includes lifting columns 331 disposed at the four corners of the mounting bracket 31, a transmission gearbox 332 disposed on the upper end of the lifting columns 331, and a rotatable component disposed on the side end of the mounting bracket 31. The lifting column 331 contains a lead screw 333, which is connected to the transmission module 32 via the transmission gear box 332. A buffer cavity 3311 is provided at one end of the lifting column 331 near the transmission gear box 332. A buffer block 3312 is slidably disposed in the buffer cavity 3311. The lead screw 333 passes through the buffer block 3312 and its lower end can abut against the lower surface of the buffer block 3312. A rotating seat is provided at the lower end of the air cover 2, and the upper end of the lead screw 333 is rotatably disposed in the rotating seat.

[0017] like Figures 1-5 As shown, the working principle of this utility model is as follows: During the lifting and lowering adjustment stage of the air cover 2, if the cumulative error due to manufacturing tolerances and assembly causes a certain lead screw 333 to reach the lifting limit position of the air cover 2 first (i.e., the upper end of the lead screw pushes the air cover 2 to the preset highest position), the lower end face of the lead screw 333 will abut against the lower surface of the buffer block 3312 and apply axial thrust, forcing the buffer block 3312 to slide upward along the axial direction of the buffer cavity 3311, gradually compressing the initial gap reserved between the two. The buffer block 3312 compensates for the axial displacement difference by axial sliding. For example, when a certain lead screw reaches the limit 10mm ahead of the diagonal lead screw, the buffer block can slide 10mm synchronously to offset the difference, avoiding the shear stress concentration of the thread profile caused by the lead screw being "forced to lock", thereby eliminating the risk of stripping failure.

[0018] As a further preferred embodiment, the transmission module 32 includes a reduction gearbox 321, a drive motor 322, a first transmission rod 323, a first transmission gearbox 324, and a second transmission rod 325. The reduction gearbox 321 is fixedly disposed in the middle of the mounting bracket 31 and its side end is connected to the output end of the drive motor 322. The first transmission rod 323 is connected to the reduction gearbox 321 in the middle and to the first transmission gearbox 324 at both ends. The second transmission rod 325 is connected to the first transmission gearbox 324 in the middle and to the second transmission gearbox 322 at its end.

[0019] Specifically, after the drive motor 322 starts, the torque is amplified by the reduction gearbox 321, driving the transmission rod 323 to rotate laterally around its own axis. At this time, the rotation of the transmission rod 323 is simultaneously diverted to both sides of the mounting bracket 31 through the two end transmission gearboxes 324, driving the two transmission rods 325 to rotate longitudinally. The longitudinal rotation of the transmission rods 325 is diverted again by the end transmission gearbox 332, converting the longitudinal rotation into the vertical rotation of the lead screw 333, and finally driving the lead screws 333 at the four corners to rotate synchronously, realizing the lifting and lowering action of the air cover 2.

[0020] As a further preferred embodiment, bearing seats 311 are fixedly provided on the mounting bracket 31 at the positions corresponding to the first transmission rod 323 and the second transmission rod 325, and the first transmission rod 323 and the second transmission rod 325 are respectively rotatably supported in the corresponding bearing seats 311 by rolling bearings.

[0021] Specifically, the bearing housing 311 provides limiting support for the transmission rod, suppresses the radial runout of the transmission rod, ensures that the speed deviation of the four corner screws 333 is within the set range, and further improves the stability of the lifting and lowering of the air cover 2.

[0022] As a further preferred embodiment, the lower edge of the air hood 2 is provided with an elastic sealing element.

[0023] Specifically, by using elastic sealing elements to improve the sealing performance between the gas hood 2 and the furnace body 1, gas leakage is effectively blocked, ensuring the sealed environment required for the curing of the coating solution, reducing defects such as pinholes in the film layer, and improving the coating yield.

[0024] As a further preferred embodiment, the air hood 2 is provided with an insulation layer inside.

[0025] Specifically, by stabilizing the heat field distribution inside the furnace through the insulation layer, the temperature difference between the inner wall of the gas hood and the curing zone inside the furnace is reduced, ensuring uniform curing of the coating solution, reducing film thickness deviation, and improving curing quality. The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
