Description

Technical Field

[0001] The utility model relates to the technical field of solid alicyclic epoxy processing, in particular to a secondary grinding device for solid alicyclic epoxy resin. Background Art

[0002] Alicyclic diepoxides are cycloaliphatic epoxy resins made by epoxidizing unsaturated alicyclic compounds with oxides. This type of epoxy resin is different from the preparation method of ordinary bisphenol A epoxy resin, has less ionic impurities, low viscosity, and good processability. Its cured product has a high degree of cross-linking, good heat resistance, strong weather resistance, resistance to ultraviolet light and resistance to electronic radiation, and is suitable for outdoor use. It also has excellent electrical properties such as arc resistance, tracking resistance, high volume resistance and surface resistance.

[0003] After conventional grinding devices process solid alicyclic epoxy resins, the products will clump during storage due to pressure and other reasons. In order to cope with some later processing that requires rapid dissolution, the materials need to be ground again. However, due to the relatively simple structure and function of the grinding device itself, the grinding effect will be affected to a certain extent when facing the agglomerated materials during the grinding process, making it difficult to make appropriate treatment, thereby further affecting the grinding effect.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a secondary grinding device for solid alicyclic epoxy resin is proposed. Utility Model Content

[0007] Further, the auxiliary frame group includes a support frame, a guide post, a lifting slider and a connecting frame. On one side of the support frame close to the device cover group, a guide post is vertically installed, and a lifting slider is installed on the surface of the guide post. Moreover, on one side of the connecting frame close to the device cover group, a connecting frame is horizontally installed.

[0008] Further, on one side of the connecting frame away from the lifting slider, it is fixedly connected to the side of the device cover group, and the lifting slider and the guide post are slidably connected.

[0010] Further, one end of the hydraulic push rod away from the stable frame is fixedly connected to the inner top end of the device cover group, and the hydraulic push rod and the stable frame are connected in an "H" - shaped structure.

[0011] Further, the grinding mechanism includes a direct - drive motor, a grinding wheel and a receiving table. The power output end of the direct - drive motor is installed with a grinding wheel through a coupling, and a receiving table is arranged between the grinding wheel and the direct - drive motor.

[0012] Further, the grinding mechanism includes a filter screen frame and a diversion cover. The edge of the receiving table is provided with a filter screen frame, and a diversion cover is installed at the bottom of the filter screen frame.

[0014] The utility model provides a secondary grinding device for solid alicyclic epoxy resin, which has the following beneficial effects:

[0015] 1. In the utility model, through the auxiliary grinding assembly installed at the inner top end of the device cover group, when the stored materials enter the inside of the crusher through the feeding pipe, after its operation, the powdery materials agglomerated due to long - term storage or storage factors can be quickly crushed, so as to facilitate subsequent secondary grinding. At the same time, through the telescopic adjustment of the hydraulic push rod in the vertical direction, the auxiliary grinding disc made of the same material as the grinding wheel at the bottom can flexibly adjust the vertical relative distance from the grinding wheel. By the interaction between the relatively static auxiliary grinding disc and the dynamically - structured grinding wheel, and under the control of the hydraulic push rod, the materials between the two auxiliary grinding discs are subjected to sufficient clamping and downward pressing forces, so as to ensure that the grinding effect can be optimized and avoid the situation of insufficient grinding.

[0016] 2. The utility model can prevent unnecessary waste of materials as much as possible by setting a receiving platform between the direct-drive motor and the grinding wheel.

At the same time, with the structural cooperation of the auxiliary grinding disc, it is combined with the receiving platform and the filter frame to form a relatively closed frame, so that the grinding wheel and the material are in the center of the interior to prevent unnecessary splashing of the material. The filter frame plays the role of filtering and screening the material to prevent the block material from mixing with the ground material. The hopper-shaped guide cover cooperates with the receiving platform to prevent the powdered material from affecting the direct-drive motor as much as possible.

[0017] 3. The utility model, through the use of the device cover group, by arranging a sound insulation layer inside the outer cover body, can minimize the noise generated by the grinding mechanism during material processing operations, and at the same time can prevent the processed powdered materials from scattering and affecting recycling. The use of the anti-static layer prevents external static electricity from being transmitted to the inside and affecting the dusty materials. In addition, the entire device cover group is connected to the lifting slider through a connecting frame, so that the entire device cover group can be lifted and lowered along the surface of the guide column. The use of the above structure can effectively ensure the flexibility of the entire structure, so that the operator can clean and maintain the various structures of the device at any time according to needs.

DETAILED DESCRIPTION

[0023] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0024] like Figures 1 to 4 As shown, a secondary grinding device for solid alicyclic epoxy resin includes a device base 1 and an auxiliary grinding assembly 4, auxiliary frame groups 2 are vertically installed on the left and right sides of the device base 1, and the auxiliary frame group 2 is connected to the device cover group 3 on one side close to the vertical central axis of the device base 1, the auxiliary grinding assembly 4 is fixedly installed on the inner top of the device cover group 3, a grinding mechanism 5 is installed in the center of the device base 1, and discharge air ducts 6 are installed at the bottom of the left and right sides of the device cover group 3. The auxiliary grinding assembly 4 includes a crusher 401, a feed pipe 402, a stabilizing frame 403, a hydraulic push rod 404, an auxiliary grinding disc 405 and a discharge port 406, the top of the crusher 401 is connected to the feed pipe 402, and the stabilizing frames 403 are symmetrically installed on the left and right sides of the crusher 401, and the top of the stabilizing frame 403 is vertically installed with a hydraulic push rod 404, and the bottom of the stabilizing frame 403 is connected to An auxiliary grinding disc 405 is connected, and a discharge port 406 is provided at the center of the auxiliary grinding disc 405. One end of the hydraulic push rod 404 away from the stabilizing frame 403 is fixedly connected to the inner top of the device cover group 3. The hydraulic push rod 404 and the stabilizing frame 403 are connected in an "H"-shaped structure. Through the auxiliary grinding component 4 installed at the inner top of the device cover group 3, when the stored material enters the crusher 401 through the feed pipe 402, it is quickly crushed. At the same time, through the telescopic adjustment of the hydraulic push rod 404 in the falling direction, the auxiliary grinding disc 405 at the bottom, which is made of the same material as the grinding wheel 502, can flexibly adjust the vertical relative distance from the grinding wheel 502, and under the control of the hydraulic push rod 404, the material between the auxiliary grinding disc 405 is sufficiently clamped and the downward grinding force is applied, so that the grinding process is carried out to the greatest extent.

[0025] The auxiliary frame group 2 includes a support frame 201, a guide post 202, a lifting slider 203 and a connecting frame 204. On the side of the support frame 201 close to the device cover group 3, a guide post 202 is vertically installed, and a lifting slider 203 is installed on the surface of the guide post 202. Moreover, on the side of the connecting frame 204 close to the device cover group 3, a connecting frame 204 is horizontally installed. The side of the connecting frame 204 away from the lifting slider 203 is fixedly connected to the side of the device cover group 3, and the lifting slider 203 and the guide post 202 are slidably connected. The device cover group 3 includes an outer cover body 301, a sound insulation layer 302 and an anti-static layer 303. The inner wall of the outer cover body 301 is provided with a sound insulation layer 302, and the inner wall surface of the sound insulation layer 302 is provided with an anti-static layer 303. By arranging a sound insulation layer 302 inside the outer cover body 301, the noise generated by the grinding mechanism 5 during the material processing operation can be reduced to the greatest extent. At the same time, it can also prevent the powdered materials from spreading everywhere during processing, affecting recovery. The use of the anti-static layer 303 is to prevent external static electricity from being conducted to the inside, thus affecting the powdery materials. In addition, the entire device cover group 3 is connected to the lifting slider 203 through the connecting frame 204, so that the entire device cover group 3 can be lifted along the surface of the guide post 202.

[0026] The grinding mechanism 5 includes a direct drive motor 501, a grinding wheel 502 and a receiving table 503. The power output end of the direct drive motor 501 is installed with a grinding wheel 502 through a coupling, and a receiving table 503 is arranged between the grinding wheel 502 and the direct drive motor 501. The grinding mechanism 5 includes a filter screen frame 504 and a diversion cover 505. The edge of the receiving table 503 is provided with a filter screen frame 504, and a diversion cover 505 is installed at the bottom of the filter screen frame 504. The receiving table 503 and the filter screen frame 504 are fixedly connected, and the cross-section of the receiving table 503 and the filter screen frame 504 is arranged in a "U" shape. The diversion cover 505 is arranged in an inverted hopper shape. Through the receiving table 503, unnecessary waste of materials can be prevented as much as possible. In cooperation with the structure of the filter screen frame 504, the materials can be ground and processed to the greatest extent. At the same time, with the structural cooperation of the auxiliary grinding disc 405, a relatively closed frame is formed with the receiving table 503 and the filter screen frame 504, so that the grinding wheel 502 and the materials are in the center, preventing unnecessary splashing of the materials. The filter screen frame 504 plays a role in filtering and screening materials, preventing lumpy materials from being mixed with the ground materials.

[0027] In summary, as Figures 1 to 4 shown, when using the secondary grinding device for solid alicyclic epoxy resin, first, the materials to be processed are gradually conveyed from the opening of the feeding pipe 402 that extends through the top of the device cover group 3 to the inside of the crusher 401 connected by a short pipe below. At this time, the operating crusher 401 will quickly crush the materials entering it, so as to break the agglomerated structure among them;

[0028] At the same time, the direct drive motor 501 will drive the grinding wheel 502 to rotate at a high speed. Then, under the processing of the crusher 401, the material will fall from the discharge port 406 opened in the center of the auxiliary grinding disc 405 to the surface of the grinding wheel 502. At the same time, the hydraulic push rod 404 connected to the top of the stabilizing frame 403 will push the auxiliary grinding disc 405 as close to the top surface of the grinding wheel 502 as possible in the vertical direction. In this process, the high-speed rotating grinding wheel 502 will form a clamping structure with the relatively static auxiliary grinding disc 405, so as to further squeeze and grind the crushed material until it is ground to the required degree. Then, under the centrifugal force of the high-speed rotating grinding wheel 502, it will fly to the filter frame 504 at the edge of the receiving platform 503, and under the vibration generated by the operation of the direct drive motor 501, the material on the surface of the filter frame 504 will be shaken and screened to prevent small block materials and dust-like materials from mixing with each other.

[0029] The falling powdery materials will slide along the guide cover 505 to the position between the bottom of the device cover group 3 and the guide cover 505, and then the dusty materials can be taken out by using the discharge air duct 6 pre-connected with the external extraction device. During the processing, the use of the outer cover 301 together with the sound insulation layer 302 can minimize the spread of noise and dust.

[0030] When it is necessary to perform maintenance and inspection on the internal structural parts of the device cover group 3, it is only necessary to move and connect the lifting slider 203 and the connecting frame 204, and the entire device cover group 3 connected to the internal auxiliary grinding component 4 is lifted vertically along the surface of the guide column 202 installed on the side of the support frame 201, so that the internal grinding mechanism 5 structure is exposed, which is convenient for the staff to operate.

[0031] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
