Description

Technical Field

[0001] The utility model relates to the technical field of PBT plastics, in particular to a PBT plastics high-efficiency screening device. Background Art

[0002] PBT plastic is a thermoplastic polyester made from the condensation of terephthalic acid and 1,4-butanediol. It is one of the five major engineering plastics and has many excellent properties, such as high heat resistance, strength, hardness and fluidity. Specifically, PBT plastic can be used for a long time at temperatures as high as 150°C without obvious thermal aging. Its tensile strength and flexural strength are higher than those of general thermoplastics. At the same time, it has good fluidity and is easy to injection mold and extrusion mold. However, PBT plastic has poor cold resistance and its brittle temperature is lower than -30°C. Therefore, in environments that need to withstand low temperatures, other materials with better cold resistance should be used.

[0003] For example, a PBT plastic screening device disclosed in publication number CN218659999U has the following beneficial effects: 1. A fan is installed inside the mounting frame, and during the screening process of the PBT plastic by the A and B screen plates, air is blown inside, thereby raising the dust attached to the surface of the PBT plastic, and then the dusty air is extracted by two sets of exhaust shells installed on the back of the screening box and the exhaust fans installed inside, thereby improving the screening effect of the screening device. 2. The PBT plastic is screened by two sets of screen plates, the A screen plate and the B screen plate, and the two sets of screen plates are installed and distributed in an inclined plate shape, thereby increasing the multiple screening effect of the PBT plastic and improving the completeness of the screening of the PBT plastic by the screening device.

[0004] The above patent uses the weight of PBT plastic particles to impact the A screen plate 103 and the B screen plate 113. Under the action of the reset spring group, the A screen plate 103 and the B screen plate 113 are shaken to achieve screening of the PBT plastic particles. However, the shaking of the reset spring group depends on the energy generated by the PBT plastic particles hitting the box. The size and frequency of this energy are unstable. When the flow rate of PBT plastic particles decreases, the screening efficiency may be affected.

[0005] Therefore, there is an urgent need for a PBT plastic efficient screening device to solve the above problems. Utility Model Content

[0022] As attached Figure 1 To Attachment Figure 3 As shown: This embodiment provides a PBT plastic efficient screening device, including a carrier plate 1, and a box body 2 is arranged above the carrier plate 1.

[0023] A transmission assembly includes a support base 3 fixedly connected to the top of the loading plate 1, a dual-axis motor 4 fixedly connected to the top of the support base 3, two output shafts of the dual-axis motor 4 are fixedly connected to a movable plate 5, one side of the movable plate 5 is fixedly connected to a round rod 6, the surface of the round rod 6 is movably connected to an adjusting plate 7, one side of the adjusting plate 7 is provided with a through hole 8 movably connected to the round rod 6, the inner walls of the two adjusting plates 7 are fixedly connected to a connecting rod 9, both ends of the connecting rod 9 are rotatably connected to a connecting plate 10, the bottom of the connecting plate 10 is fixedly connected to the loading plate 1, two fixed plates 11 are sleeved on the surface of the connecting rod 9, the top of the fixed plate 11 is fixedly connected to the box body 2, and the four corners of the top of the loading plate 1 are provided with a stabilizing assembly 12, the inner cavity of the box body 2 is fixedly connected with a screen 13 and a screen 2 14 from top to bottom, and the box body 2, the transmission assembly, the stabilizing assembly 12, the screen 13 and the screen 2 14 are all inclined.

[0024] Specifically, the stabilizing component 12 includes a spherical sleeve 121 fixedly connected to the carrier plate 1, the inner cavity of the spherical sleeve 121 is movably connected to a spherical block 122, the top of the spherical block 122 is fixedly connected to an outer tube 123, the inner cavity of the outer tube 123 is slidably connected to an inner rod 124, the top of the inner rod 124 penetrates to the outside of the outer tube 123 and is fixedly connected to a spherical block 125, the surface of the spherical block 125 is movably connected to a spherical sleeve 126, and the top of the spherical sleeve 126 is fixedly connected to the box 2.

[0025] In this embodiment: through the setting of the stabilizing component 12, when the box body 2 shakes back and forth, it can drive the spherical sleeve 126 to move. At this time, the spherical block 125 moves in the inner cavity of the spherical sleeve 126, and the spherical block 122 moves in the inner cavity of the spherical sleeve 121. The box body 2 will drive the inner rod 124 to slide in the inner cavity of the outer tube 123 with the help of the transmission of the spherical sleeve 126 and the spherical block 125, which is used to compensate for the movement of the box body 2. At the same time, with the use of the stabilizing component 12, the safety of the box body 2 during movement is improved.

[0026] Specifically, the bottom end of the inner rod 124 is fixedly connected with a slider 127, the slider 127 is located in the inner cavity of the outer tube 123 and is slidably connected with the outer tube 123, and the surface of the inner rod 124 is sleeved with a spring 128, and the two ends of the spring 128 are fixedly connected with the outer tube 123 and the slider 127 respectively.

[0027] In this embodiment: through the coordinated use of the slider 127 and the spring 128, the inner rod 124 will drive the slider 127 to slide in the inner cavity of the outer tube 123, which is used to limit the inner rod 124. At the same time, the slider 127 will stretch or squeeze the spring 128 when it moves, and under the elastic potential energy of the spring 128, it will help the box 2 to shake.

[0028] Specifically, one end of the round rod 6 extends to the outside of the through hole 8 and is fixedly connected to the limiting block 15 , and the diameter of the limiting block 15 is greater than the diameter of the round rod 6 .

[0029] In this embodiment, the limiting block 15 is used to position the round rod 6 and prevent the round rod 6 and the adjusting plate 7 from being separated.

[0030] Specifically, the right side of the box body 2 is fixedly connected with a guide plate 16 and a guide plate 2 17 in sequence from top to bottom. The guide plate 16 and the guide plate 2 17 are used in conjunction with the screen 13 and the screen 2 14 respectively.

[0031] In this embodiment, by using the guide plate 1 16 and the guide plate 2 17 in coordination, the PBT plastic particles screened by the screen 1 13 and the screen 2 14 are outputted through the guide plate 1 16 and the guide plate 2 17 respectively, thereby achieving the purpose of guiding the PBT plastic particles.

[0032] The working principle and use process of the utility model are as follows: when in use, the dual-axis motor 4 is started, and the two output shafts of the dual-axis motor 4 drive the movable plate 5 to rotate, and the movable plate 5 drives the round rod 6 to move in the inner cavity of the through hole 8. Since there is a space between the bottom of the adjusting plate 7 and the loading plate 1, the round rod 6 can drive the adjusting plate 7 to swing back and forth when it moves in the inner cavity of the through hole 8. The adjusting plate 7 drives the connecting rod 9 to rotate, and the connecting rod 9 drives the box body 2 to rock back and forth through the transmission of the fixed plate 11. When the box body 2 rocks back and forth, it can drive the spherical sleeve 2 126 to move. At this time, the spherical block 2 125 moves in the inner cavity of the spherical sleeve 126, and the spherical block 122 moves in the inner cavity of the spherical sleeve 121, and the box body 2 will drive the inner cavity of the spherical sleeve 126 and the spherical block 125 with the help of the transmission of the spherical sleeve 126 and the spherical block 125. The rod 124 slides in the inner cavity of the outer tube 123 to compensate for the movement of the box body 2. At the same time, the use of the stabilizing component 12 also improves the stability of the box body 2. Then the PBT plastic particles are transported to the inner cavity of the box body 2. By shaking the box body 2 back and forth, the PBT plastic particles are initially screened through the screen 13, and the smaller PBT plastic particles fall into the top of the screen 2 14. Under the continuous shaking of the box body 2, the PBT plastic particles are secondary screened through the screen 2 14, and finally fall into the bottom of the inner cavity of the box body 2. Since the box body 2 is tilted as a whole, the screened PBT plastic particles are output from the right side of the box body 2, thereby achieving the purpose of efficient screening of the PBT plastic particles. At the same time, with the help of the dual-axis motor 4 as the power source, the stability of the screening efficiency is guaranteed.
