[0002] PVC granules are high-molecular composite material particles made of polyvinyl chloride resin as the main body, with the addition of plasticizers, stabilizers, lubricants, fillers and other additives. PVC granule cooling vibrating screen is a key piece of equipment in the plastics processing field, mainly used to simultaneously achieve granule grading, screening and cooling treatment.
[0003] In the prior art, PVC granule vibrating screens generally vibrate longitudinally. When too much PVC granule is fed at once, it is easy to accumulate on the vibrating screen, which makes it difficult to screen the PVC granule smoothly and affects the screening efficiency of the vibrating screen. Therefore, a PVC granule cooling vibrating screen is proposed to solve the above problems. Utility Model Content

The controller is fixedly installed on the front surface of the cooling screening box. Two opening slots are opened on each of the two opposite surfaces of the cooling screening box. Sliding plates are slidably installed between the two opening slots. The two ends of the two sliding plates extend to the outside of the cooling screening box through the opening slots. Mounting grooves are opened on the upper surface of the two sliding plates. Screening screens are installed inside the two mounting grooves. Two mounting sleeves are bolted to one surface of the cooling screening box. The positions of the two mounting sleeves correspond to the positions of the two sliding plates. The two sliding plates are slidably connected to the inside of the mounting sleeves.
[0007] Furthermore, each of the two sliding plates has a groove at one end, and one end of the screening screen extends to the outside of the sliding plate through the groove. Two guide grooves are also provided at one end of the screening screen.
[0008] Furthermore, the two guide grooves are respectively arranged on both sides of the slide groove, and a connecting rod is welded to the other end of each of the two sliding plates. A connecting plate is welded to one end of each of the two connecting rods, and a sound-absorbing pad is pasted on one surface of the connecting plate.
[0009] Furthermore, two guide rods are welded to one inner surface of each of the two mounting sleeves, the positions of the two guide rods correspond to the positions of the two guide grooves, and one end of each guide rod is slidably connected to the guide groove.
[0010] Furthermore, an annular plate is slidably mounted on the periphery of both guide rods, and a return spring is installed between one surface of the annular plate and one inner surface of the mounting sleeve, with the two return springs wrapped around the periphery of the guide rods.
[0011] Furthermore, a mounting plate is welded to another surface of the cooling screening box, and a drive motor is fixedly mounted on one surface of the mounting plate. The drive motor is electrically connected to the controller, and a rotating shaft is connected to the output end of the drive motor via a keyway.

[0029] Please see Figures 1-6As shown, this utility model is a PVC granule cooling vibrating screen, including a cooling screening box 1 and a controller 2. The controller 2 is fixedly installed on the front surface of the cooling screening box 1. Two opening slots 102 are opened on both opposite surfaces of the cooling screening box 1. Sliding plates 103 are slidably installed between the two opening slots 102. The two ends of the two sliding plates 103 extend to the outside of the cooling screening box 1 through the opening slots 102. The upper surface of the two sliding plates 103 is provided with mounting slots 104. Screening screens 105 are installed inside the two mounting slots 104. Two mounting sleeves 111 are bolted to one surface of the cooling screening box 1. The positions of the two mounting sleeves 111 correspond to the positions of the two sliding plates 103. The two sliding plates 103 are slidably connected to the inside of the mounting sleeves 111, so that the two sliding plates 103 and the screening screens 105 move back and forth quickly in the horizontal direction, realizing the transverse vibration of the screening screens 105. When PVC granules are piled up, they can be broken up and screened by rapid transverse vibration, ensuring the screening efficiency of the device.
[0030] Both sliding plates 103 have a groove 106 at one end, and one end of the screening screen 105 extends to the outside of the sliding plate 103 through the groove 106. Two guide grooves 110 are also provided at one end of the screening screen 105.
[0031] Two guide grooves 110 are respectively set on both sides of the slide groove 106. A connecting rod 107 is welded to the other end of each of the two sliding plates 103. A connecting plate 108 is welded to one end of each of the two connecting rods 107. A sound-absorbing pad 109 is pasted on one surface of the connecting plate 108.
[0032] Two guide rods 112 are welded to one inner surface of each of the two mounting sleeves 111. The positions of the two guide rods 112 correspond to the positions of the two guide grooves 110, and one end of the guide rod 112 is slidably connected to the guide groove 110.
[0033] Both guide rods 112 have annular plates 113 slidably mounted on their circumferential sides. A return spring 114 is installed between one surface of the annular plate 113 and one inner surface of the mounting sleeve 111. The two return springs 114 are wrapped around the circumferential sides of the guide rods 112.
[0034] A mounting plate 3 is welded to another surface of the cooling screening box 1. A drive motor 301 is fixedly mounted on one surface of the mounting plate 3. The drive motor 301 is electrically connected to the controller 2. A rotating shaft 302 is connected to the output end of the drive motor 301 via a keyway. An eccentric wheel 303 is welded to one end of the rotating shaft 302. One end of the eccentric wheel 303 is in contact with the sound-absorbing pad 109.
[0035] The lower surface of the cooling screening box 1 is welded with a discharge end 101. Side plates 5 are welded to the sides of the cooling screening box 1. Support columns 6 are welded to the lower surface of the side plates 5. A cooling air box 4 is provided above the cooling screening box 1. A small ventilation slot 401 is opened on the upper surface of the cooling air box 4. Support plates 402 are welded to the two opposite surfaces of the cooling air box 4. The two support plates 402 are welded and fixed to the upper surface of the cooling screening box 1.
[0036] Please see Figures 1-6 As shown, this utility model is a PVC granule cooling vibrating screen. Its usage method is as follows: First, PVC granules are fed into the cooling screening box 1. Then, the cooling air box 4 is activated to continuously supply cold air into the cooling screening box 1 to cool the PVC granules. Next, the controller 2 starts the drive motor 301, which drives the rotating shaft 302 and the eccentric wheel 303 to rotate. When the eccentric wheel 303 rotates, one end of it regularly impacts the sound-absorbing pad 109. When the sound-absorbing pad 109 is impacted, it drives the connecting plate 108 and the sliding plate 1... 03. When the sliding plate 103 moves laterally, one end of the sliding plate 103 moves towards the cooling screening box 1, while the other end slides inside the mounting sleeve 111. At this time, one end of the guide rod 112 slides into the guide groove 110, and the annular plate 113 slides on the guide rod 112, causing the reset spring 114 to deform and compress. When the eccentric wheel 303 rotates to the other end, the reset spring 114 resets, pushing the annular plate 113 and the sliding plate 103 to reset. The above steps are repeated so that the sliding plate 103 and the screening screen 105 move back and forth to achieve lateral vibration and screen the PVC granules.
