[0002] Polyester resin is a general term for high molecular compounds formed by polycondensation of diols or dibasic acids or polyols and polybasic acids. Polyester resins are divided into saturated polyester resins and unsaturated polyester resins. Unsaturated polyester adhesives are mainly composed of unsaturated polyester resins, pigments and fillers, initiators and other additives. The adhesive has a small viscosity, is easy to wet, and has good processability. The cured adhesive layer has a large hardness, good transparency, high brightness, can be quickly cured at room temperature under pressure, has good heat resistance, and excellent electrical properties. The disadvantages are large shrinkage rate, low adhesive toughness, poor chemical medium resistance and water resistance, and is used for non-structural adhesives. It is mainly used for bonding fiberglass, hard plastics, concrete, electrical potting, etc.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] (1). For this polyester resin pulverizing device, start the motor. The pulverizing mechanism swings left and right by driving through the connecting plate, so that the pulverizing balls slide inside the base to pulverize the polyester resin inside it. By rotating the second rod disk, the threaded rotation between the threaded rod and the threaded hole can be realized, so that the rear plate adjusts its up and down position driven by the second support rod, thereby changing the distance between the base and the pulverizing balls, and thus being able to control the fineness of the polyester resin ground and pulverized by the pulverizing balls, which is convenient for the adjustment of the device.

[0016] (2). For this polyester resin pulverizing device, the center of the main ring is below the center of the screen, so the radian of the base is larger than the swinging radian of the main ring. Thus, when the pulverizing balls are at the center of the bottom of the base, at this time the pulverizing balls are closest to the base. As they deviate from the center position of the bottom of the base, the distance between the pulverizing balls and the base will gradually increase. Therefore, when pulverizing the polyester resin, the polyester resin is roughly ground by the large distance between the pulverizing balls and the side of the base, and the polyester resin is finely ground by the pulverizing balls and the center position of the bottom of the base. Finally, the pulverized polyester resin will also be produced through the second outlet, the first outlet and passing through the screen. In this way, the device can roughly grind the polyester resin once before finely grinding it, so that the pulverizing effect on the polyester resin is better.

[0017] (3). For this polyester resin pulverizing device, when the pulverizing balls swing inside the base to grind it, they will also push a part of the polyester resin to move inside the base. In addition, through the contact between the vibrating column and the corrugated plate, the swinging of the pulverizing balls inside the base will cause the base to vibrate slightly. Combined with the arc shape of the base, the polyester resin accumulated at the side position of the base can be timely moved down, ensuring the sinking of the polyester resin and being beneficial to the pulverizing of the polyester resin.

[0018] (4). In this polyester resin crushing device, the aperture of the sieve holes opened on the sieve gradually increases. When the sieve needs to be rotated, first pull out the handle so that the insertion post is pulled out of the insertion hole. At this time, rotate the handle, and drive the second roller to rotate through the cross post and the cross groove, thereby driving the sieve to rotate. After the sieve rotates to the appropriate position, re-insert the insertion post facing the insertion hole into the insertion hole, thereby completing the rotation locking of the second roller and fixing the sieve. By adjusting the specific aperture size of the sieve to face the first outlet, various specifications of polyester resin crushing requirements can be met in cooperation with the device, improving the crushing fineness of the device.

[0019] (5). In this polyester resin crushing device, during the swinging process of the crushing mechanism, the upper ball will also synchronously push the lower plate, so that the baffle plate stirs the uncrushed polyester resin inside the raw material bin, avoiding the caking of the polyester resin inside the raw material bin and facilitating the device to grind the polyester resin.

[0020] (6). In this polyester resin crushing device, through the swinging of the baffle plate, when the baffle plate deflects to one side, it will touch the thin rod at this time, thereby moving the plug plate downward and opening the feeding pipe. At this time, the polyester resin inside the raw material bin will automatically fall through the feeding pipe and the slide rail to the middle part of the base, thereby completing the automatic feeding of the polyester resin and improving the automation performance of the device.

In the middle of the upper surface of the blocking plate 507, a thin rod 509 is fixedly connected. The spring 508 is wound around the outside of the thin rod 509. The end of the thin rod 509 far from the blocking plate 507 passes through the blanking pipe 506 and extends into the inside of the raw material bin 501; The hole grooves on the dial plate 504 opposite to the thin rod 509 are fixedly filled with hole groove blocks.

[0040] Working principle:

[0041] First step: Start the motor 107. The crushing mechanism 2 swings left and right through the rotation of the connecting plate 106, so that the crushing balls 205 slide inside the base 301 to crush the polyester resin inside. By rotating the rotating rod disk two 315, the threaded rotation between the threaded rod 314 and the threaded hole 102 can be realized, so that the rear plate 309 adjusts its up and down position under the drive of the support rod two 313, thereby changing the distance between the base 301 and the crushing balls 205, so as to control the fineness of the polyester resin ground and crushed by the crushing balls 205, which is convenient for the adjustment of the device.

[0042] Step 2: The center of the main ring 201 is located at the lower side of the center of the screen 316, so that the curvature of the base 301 is larger than the swing curvature of the main ring 201. Therefore, when the crushing ball 205 is located at the bottom center of the base 301, the crushing ball 205 is closest to the base 301. As it deviates from the bottom center of the base 301, the distance between the crushing ball 205 and the base 301 will gradually increase. Therefore, when the polyester resin is crushed, the long distance between the crushing ball 205 and the side of the base 301 is used to coarsely grind the polyester resin, and the crushing ball 205 and the bottom center of the base 301 are used to finely grind the polyester resin. Finally, the crushed polyester resin will be screened through the outlet 2 308 and the outlet 1 304 and the screen 316 and then output. In this way, the device can coarsely grind the polyester resin before fine grinding, which has a better crushing effect on the polyester resin.

[0043] Step 3: When the crushing ball 205 swings inside the base 301 to grind it, it will also push a part of the polyester resin to move inside the base 301. In addition, through the contact between the vibration column 206 and the corrugated plate 305, the swing of the crushing ball 205 inside the base 301 will cause the base 301 to vibrate slightly. Combined with the arc shape of the base 301, the polyester resin accumulated on the side of the base 301 can move down in time, ensuring the sinking of the polyester resin, which is beneficial to the crushing of the polyester resin.

[0044] Step 4: The aperture of the sieve holes on the screen 316 gradually increases. When the screen 316 needs to be rotated, first pull out the handle 406 to pull the plug post 407 out of the socket 302. At this time, turn the handle 406 to drive the roller 2 404 to rotate through the cross column 408 and the cross groove 405, thereby driving the screen 316 to rotate. After the screen 316 is rotated to a suitable position, the plug post 407 facing the socket 302 is reinserted into the socket 302 to complete the rotation locking of the roller 2 404, thereby fixing the screen 316. By adjusting the specific aperture size of the screen 316 to face the outlet 1 304, the device can be used to meet the crushing requirements of polyester resins of various specifications, thereby improving the crushing fineness of the device.

[0045] Step 5: During the swinging of the crushing mechanism 2, the upper ball 204 will also synchronously move the lower plate 503, so that the plate 504 stirs the uncrushed polyester resin inside the raw material bin 501 to avoid agglomeration of the polyester resin inside the raw material bin 501, making it easier for the device to grind the polyester resin.

[0046] Step 6: Through the swing of the dial plate 504, when the dial plate 504 biases to one side, it will contact the thin rod 509 at this time, thereby moving the plug plate 507 downward, opening the blanking pipe 506. At this time, the polyester resin inside the raw material bin 501 will automatically fall through the blanking pipe 506 and the slide rail 505 to the middle part of the base 301, thus completing the automatic blanking of the polyester resin and improving the automation performance of the device.
