Technical Field

[0001] The present invention relates to the technical field of resin grinding wheel production equipment, and more specifically, to a curing device for resin grinding wheel production. Background Art

[0002] In the traditional production process of resin grinding wheels, after the resin grinding wheels are cold-pressed and formed, they are sent into a curing furnace, and the air circulation in the curing furnace is used to uniformly heat the resin grinding wheels to achieve the curing treatment of the resin grinding wheels.

[0003] Currently, there are obvious defects in the design of some curing devices, resulting in unsatisfactory curing effects. The heating components of some curing devices are arranged around the edge of the resin grinding wheel, and the heat conduction sequence is from the edge to the center first. This heating method makes the central part heat up laggingly, resulting in inconsistent curing degrees between the center and the edge of the grinding wheel, seriously affecting the uniformity of the overall performance of the grinding wheel. At the same time, the temperature distribution in the curing cabinet is uneven, the temperature in the area close to the heat source is relatively high, while the temperature in the area far from the heat source is relatively low. This makes the heating conditions of the resin grinding wheels placed in different positions vary significantly, thereby causing uneven curing quality, increasing the defective rate of products. In view of this, we propose a curing device for resin grinding wheel production. Summary of the Invention

[0039] In an embodiment of the present invention, a mounting seat 101 for mounting a heating element 2 is fixedly provided on the inner wall of the curing cabinet 1, and the cross-sectional shape of the mounting seat 101 is a right triangle, and the inclined surfaces of the mounting seats 101 on both adjacent sides face opposite directions; the setting of the mounting seat 101 can change the direction in which heat is emitted by the heating elements 2 on both sides to achieve a gathering effect, and the strength of the heat curing of the resin grinding wheel can be enhanced in combination with the self-rotation effect.

[0040] Working principle: This embodiment provides a curing device for resin grinding wheel production. The curing device takes a curing cabinet 1 in an L shape as the main body. The mounting seat 101 on the inner wall of the curing cabinet 1 is used to install the heating element 2. The design of the right-angled triangular cross-section of the mounting seat 101 with the inclined surfaces of adjacent sides facing in opposite directions may help the heating element 2 change the heating range, strengthening the heating effect while providing the basic heating function.The rotating bracket 3 inside the curing cabinet 1 is used to place resin grinding wheels. The driving motor 301 drives the turntable 302 to rotate, and then the entire rotating bracket 3 rotates, realizing the rotation of the resin grinding wheels during the curing process to ensure uniform heating. The hot air blower 8 is installed on the top of the protruding end of the curing cabinet 1 and blows hot air inward. It enters the interior of the curing cabinet 1 through the air outlet pipe 801 connected to the hot air blower 8. A number of air outlets on the opposite surfaces of the air outlet pipe 801 blow out the hot air evenly, and together with the heating element 2, a circulating hot air environment is formed inside the curing cabinet 1 to accelerate the curing process of the resin grinding wheels. The driving motor 301 is installed on the top of the partition plate 102, and its output end penetrates through the baffle 103 to drive the turntable 302 to rotate. The three fixing frames 4 on the top of the turntable 302, the connecting plate 303, and the connecting round block 304 together form a bracket structure. The fixing frame 4 is composed of a number of C-shaped plates 401, connecting rods 402, and positioning rods 403, providing an installation basis for the object placing assembly 5. And the design of the C-shaped plate 401 can expand the range of the top of the object placing assembly 5, reduce the resistance of taking and placing resin grinding wheels, and improve the convenience of taking and placing operations. The placing table 501 of the object placing assembly 5 is clamped with the connecting rod 402 through the clamping buckle 502 to realize the installation and fixation of the placing table 501. The fan blades 503 on the placing table 501 will disturb the surrounding air during rotation, further promoting the circulation and uniform distribution of hot air. At the same time, the spiral turbulator grooves 505 at the bottom also contribute to the air flow and heat transfer. The positioning groove 504 on the top of the placing table 501 is used to place the positioning seat 6. The bottom diameter of the positioning groove 504 is smaller than the top diameter, achieving the effect of easy placement of the positioning seat 6. The fan-shaped positioning block 602 on the top of the base 601 of the positioning seat 6 can be inserted into the central hole of the resin grinding wheel to realize the positioning of the resin grinding wheel. The supporting protrusion 603 supports the bottom of the resin grinding wheel to keep it stable during the curing process, and at the same time, it can also increase the contact range with hot air. The handle block 604 and the limiting support block 605 facilitate the handling and placement of the positioning seat 6 and the resin grinding wheel. Tools can be used instead of hand-held methods to improve the safety of taking and placing operations. The ventilation slots are opened on the fixing plate 104 between the inner walls of the top of the curing cabinet 1, which does not affect the hot air circulation. The clamping member 7 at the bottom is composed of a cross plate 701, a C-shaped clamping member 702, and an elastic folding plate 703. The C-shaped clamping member 702 is rotationally combined with the connecting round block 304 to ensure the stability of the rotating bracket 3 during rotation, achieving the effect of easy assembly. The poisonous gas generated during the curing process can move into the poisonous gas treatment device 9 through the ventilation slots, so that the poisonous gas generated inside can be treated to ensure the safety of the working environment. The poisonous gas treatment device 9 is a prior art structure and will not be described in detail here. The overall structural layout is reasonable, and with the self-rotation function, it can effectively improve the uniformity of heat absorption of the resin grinding wheels during the curing process and enhance the curing quality.

Those of ordinary skill in the art can easily understand the spirit of the present invention based on the above embodiments and make different extensions and changes. However, as long as they do not depart from the spirit of the present invention, they are within the protection scope of the present invention.
