Description

Technical Field

[0001] This utility model relates to the field of plastic product manufacturing technology, and in particular to a granule screening machine for processing plastic products. Background Technology

[0002] Chinese Patent No. CN219902913U discloses a granule screening machine, relating to the field of plastic product manufacturing technology. The machine includes a screening box with a guide hopper fixedly connected to its top. Inside the screening box are two vertically arranged, inclined filter screens. Two sets of symmetrical movable grooves are provided on both sides of the screening box. A mounting plate is slidably connected inside each movable groove, and the mounting plate is detachably connected to the filter screens. An elastic element is fixedly connected inside each movable groove, with one end of the elastic element fixedly connected to the mounting plate. When the filter screens screen granules, the operation of the striking component causes the internal structure of the striking component to reciprocate, causing the filter screens to shake up and down, thereby increasing the granule screening speed. The vibration generated when the filter screens are struck prevents clogging during granule screening, thus improving screening efficiency.

[0003] This device can be used for screening plastic granules by screening the granules through a filter screen. At the same time, the filter screen is shaken up and down to increase the screening speed and prevent clogging. However, the device does not have a structure for switching screening sizes. Also, the screened granules can only be discharged by gradually vibrating and sliding down, which affects the screening efficiency. Furthermore, before they are discharged, they may affect the discharge of other granules. Therefore, an improvement is proposed. Utility Model Content

[0004] The purpose of this invention is to solve the problems of existing technologies that lack a structure for switching screening sizes, and where the screened particles can only be discharged by gradually vibrating and sliding down, affecting screening efficiency and potentially affecting the discharge of other particles before being discharged. Therefore, this invention proposes a particle screening machine for plastic product processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A granule screening machine for plastic product processing is designed, comprising a sleeve, an inner cylinder rotatably connected inside the sleeve, multiple sets of screen plate grooves formed on the outer end face of the inner cylinder, screening plates fixedly installed inside the screen plate grooves, and inlet and outlet ports that cooperate with the screen plate grooves on the outer end face of the sleeve. A first support frame and a second support frame are respectively provided on the left and right sides of the sleeve, and the sleeve is rotatably connected between the first support frame and the second support frame through the cooperation of a rotating shaft. A first driving structure for driving the sleeve to rotate is provided on the outer side of the first support frame, and a second driving structure for driving the inner cylinder to rotate is provided on the outer side of the second support frame.

[0007] Preferably, the first drive structure includes a first motor frame fixedly connected to the outer end face of the first support frame, a second motor fixedly installed inside the first motor frame, and the output shaft of the second motor being drively connected to the rotating shaft.

[0008] Preferably, the second drive structure includes a mounting groove formed inside the rotating shaft, a second motor frame is fixedly connected inside the mounting groove, a partition plate is provided inside the second motor frame, a first motor is fixedly installed on the outer end face of the partition plate, and the output shaft of the first motor is connected to the inner cylinder drive.

[0009] Preferably, the number of screening plates is set to the number of screening plate slots minus one, and the screening plates have several sets of through holes inside, with the diameter of the through holes of the multiple sets of screening plates increasing sequentially.

[0010] Preferably, the sleeve has a single-sided opening structure, and a fixing cap is fixedly connected to the opening of the sleeve by bolts, and the inner cylinder is inserted into the sleeve through the opening.

[0011] Preferably, the first support frame and the second support frame are fixedly installed inside the box body by bolts, and the box body has a feeding port at the top and a discharging port at the bottom.

[0012] Preferably, a disintegration mechanism is fixedly installed inside the inner cylinder.

[0013] The present invention discloses a granule screening machine for plastic product processing, which has the following advantages: A sleeve is fixed by the cooperation of a first support frame and a second support frame. An inner cylinder is rotatably connected inside the sleeve. The inner cylinder contains multiple sets of screening plates with different through-hole diameters. The inlet / outlet is aligned with the feed inlet. When the empty screen plate slot coincides with the inlet / outlet, granules to be screened can be fed in from above. At this time, the inner cylinder is driven to rotate by a first motor, causing the screening plate that meets the screening size to coincide with the inlet / outlet. Driven by a second motor, the sleeve rotates, causing the granules inside to tumble and be screened and discharged. Simultaneously, a dispersing mechanism can improve the tumbling effect of the granules, increasing screening efficiency. Thus, the granules to be screened can be easily discharged under rotation. The empty screen plate slot re-aligns with the inlet / outlet to discharge the remaining granules. Alternatively, the inner cylinder can be rotated to align different screening plates with the inlet / outlet, enabling multiple screenings of granules of different sizes, thus improving screening capacity.

A first support frame 4 and a second support frame 401 are respectively arranged on the left and right sides of the sleeve 1. The sleeve 1 is rotatably connected between the first support frame 4 and the second support frame 401 through a rotating shaft 103. A first driving structure for driving the sleeve 1 to rotate is arranged on the outer side of the first support frame 4, and a second driving structure for driving the inner cylinder 2 to rotate is arranged on the outer side of the second support frame 401. The sleeve 1 is fixed by the cooperation of the first support frame 4 and the second support frame 401, and the inner cylinder 2 is rotatably connected inside the sleeve 1, so that the screening plates 3 that meet the screening size coincide with the inlet / outlet 101. Rotating the sleeve 1 causes the granules inside to tumble and be screened out, thus easily discharging the granules that need to be screened through rotation.

[0022] refer to Figure 5To facilitate material feeding and discharging, the number of screening plates 3 is set to one less than the number of screen plate grooves 201. Several sets of through holes are opened inside the screening plates 3, and the diameter of the through holes of multiple sets of screening plates 3 increases sequentially. By rotating the screening plates 3 of different diameters to coincide with the inlet and outlet 101, different particles can be screened.

[0023] refer to Figure 5 To facilitate the installation of the inner cylinder 2, the sleeve 1 is designed with a single-sided opening. A fixing cap 102 is fixedly connected to the opening of the sleeve 1 by bolts. The inner cylinder 2 is inserted into the sleeve 1 through the opening.

[0024] To prevent particles from scattering everywhere, the first support frame 4 and the second support frame 401 are fixedly installed inside the box with bolts. The top of the box has a feeding port and the bottom of the box has a discharging port. A dispersing mechanism is fixedly installed inside the inner cylinder 2. The dispersing mechanism includes a central shaft and a dispersing roller or a central shaft and a auger blade. The screening efficiency can be improved by setting up a dispersing mechanism.

[0025] refer to Figure 3 A first driving structure is provided to drive the sleeve to rotate. The first driving structure includes a first motor frame 402 fixedly connected to the outer end face of the first support frame 4. A second motor 601 is fixedly installed inside the first motor frame 402. The output shaft of the second motor 601 is connected to the rotating shaft 103. The second motor 601 can be installed through the first motor frame 402. The second motor 601 can drive the sleeve 1 to rotate, thereby performing screening.

[0026] refer to Figure 4 A second drive structure is provided to drive the inner cylinder 2 to rotate. The second drive structure includes a mounting groove 104 opened inside the rotating shaft 103. A second motor frame 5 is fixedly connected inside the mounting groove 104. A partition plate 501 is provided inside the second motor frame 5. A first motor 6 is fixedly installed on the outer end face of the partition plate 501. The output shaft of the first motor 6 is connected to the inner cylinder 2 for transmission. The first motor 6 can be installed through the cooperation of the second motor frame 5 and the partition plate 501. The inner cylinder 2 can be driven to rotate by the first motor 6.

[0027] Working method: During operation, the sleeve 1 is fixed by the cooperation of the first support frame 4 and the second support frame 401. An inner cylinder 2 is rotatably connected inside the sleeve 1. The inner cylinder 2 contains multiple sets of screening plates 3 with different through-hole diameters. When the inlet / outlet 101 is aligned with the feed port of the housing, and the empty screen plate groove 201 coincides with the inlet / outlet 101, particles to be screened can be fed in from above. Then, the inner cylinder 2 is driven to rotate by the first motor 6, causing the screening plates 3 that meet the screening size to coincide with the inlet / outlet 101. Thus, the second motor... Driven by machine 601, the sleeve 1 is rotated, causing the internal particles to tumble and be screened out. At the same time, the particle tumbling effect can be improved by the dispersing mechanism, thus improving the screening efficiency. In this way, the particles that need to be screened can be discharged under the rotation of the sleeve 1. At this time, the inner cylinder 2 is rotated so that different screening plates 3 are aligned with the inlet and outlet 101, which can perform multiple screenings of particles of different sizes, thereby improving the screening capacity. After screening, the empty screen plate groove 201 is aligned with the inlet and outlet 101 again, and the remaining particles can be discharged for the next screening.
