AI Technical Summary
When existing high-efficiency drying and dehumidification devices dry and dehumidify plastic particles, the moisture on the surface of the plastic particles easily forms liquid bridges, causing adhesion and agglomeration, which affects the uniformity of drying and dehumidification and the quality of the finished product.
The design employs a control cam and a flexible striking block. The drive motor drives the transmission system to generate periodic vibrations in the screen. The high-frequency oscillation of the elastic metal sheet drives the flexible striking block to gently strike the screen frame, breaking up the agglomerated plastic particles and forming a uniform flow layer.
This effectively prevents plastic particles from agglomerating and clumping, improves the uniformity and convenience of drying and dehumidification, and ensures the quality of the finished plastic particles.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic particle processing technology, and in particular to a high-efficiency drying and dehumidification device. Background Technology
[0002] In the process of plastic particle production, in order to ensure product performance and stability and facilitate subsequent use, it is usually necessary to reduce the moisture content of the plastic particles. To reduce the moisture content of the plastic particles, workers usually use high-efficiency drying and dehumidification devices to dry and dehumidify the plastic particles. Existing high-efficiency drying and dehumidification devices are usually composed of a frame, a screen and a fan.
[0003] For example, utility model application CN202121206079.5 discloses a plastic particle dehumidification and drying device, specifically including: a mounting base; a frame mounted on the mounting base; a support frame, at least two of which are mounted inside the frame; a fan, at least two of which are mounted on the support frame; a pushing mechanism mounted on the frame; and a feeding mechanism mounted on the frame. This utility model, through the cooperation of a movable plate and a screen, allows the plastic particles to change position during dehumidification and drying, thereby accelerating the dehumidification and drying process. The screen allows the plastic particles requiring dehumidification and drying to be placed on it, and the feeding frame allows the dehumidified and dried plastic particles to be collected.
[0004] However, in terms of current traditional high-efficiency drying and dehumidification devices, plastic particles are usually placed on a screen and dried by a fan. However, during the drying and dehumidification process, the residual moisture on the surface of the plastic particles can easily form liquid bridges, causing the plastic particles to stick together and form agglomerates. This results in uneven drying and dehumidification of the plastic particles, affecting the quality of the finished plastic particles and making them inconvenient to use. Utility Model Content
[0005] In view of this, the present invention provides a high-efficiency drying and dehumidification device, which has a control cam and a flexible striking block to prevent plastic particles from agglomerating. By starting the drive motor, the drive motor drives the first bevel gear to rotate, which in turn drives the second bevel gear meshing with it to rotate, causing the transmission shaft to drive the first pulley to rotate. As the first pulley rotates, it drives the second pulley to rotate through the transmission belt. As the second pulley rotates, it drives the two control shafts on the left to rotate. Subsequently, through the cooperation of the third and fourth pulleys, all four control shafts rotate simultaneously. As the control shafts rotate, the control cam rotates, which pushes the connecting slide plate to move, causing the connecting slide plate to move the screen upward. When the control cam does not push the connecting slide plate, the connecting slide plate will fall under its own weight, thus causing the screen to vibrate periodically. During the screen vibration, the elastic metal sheet will generate high-frequency oscillation due to resonance. As the elastic metal sheet oscillates at high frequency, it drives the flexible striking block to periodically tap the screen frame.
[0006] This utility model provides a high-efficiency drying and dehumidification device, specifically including: a mounting frame; four support columns are fixedly connected to the bottom surface of the mounting frame in a rectangular array; two connecting slide plates are symmetrically slidably connected to the upper part of the mounting frame; screens are provided on the top surfaces of the two connecting slide plates; multiple sets of hot air fans are installed inside the mounting frame; the positions of the multiple sets of hot air fans are aligned with the screens; a connecting frame is fixedly connected to the outside of the mounting frame; a drive motor is bolted to the left end face of the connecting frame; two transmission shafts are symmetrically rotatably connected to the left side of the connecting frame; and two control shafts are symmetrically rotatably connected inside the mounting frame.
[0007] Optionally, a first bevel gear is coaxially fixedly connected to the end of the drive motor shaft; a second bevel gear is coaxially fixedly connected to the inner side of each of the two transmission shafts; both second bevel gears mesh with the first bevel gear.
[0008] Optionally, a first pulley is coaxially fixedly connected to the outer side of each of the two transmission shafts; a second pulley is coaxially fixedly connected to the outer side of each of the two control shafts on the left; the two second pulleys are respectively connected to the two first pulleys via transmission belts.
[0009] Optionally, a third pulley is coaxially fixedly connected to the outside of each of the two control shafts on the left; a fourth pulley is coaxially fixedly connected to the outside of each of the two control shafts on the right; the two third pulleys are respectively connected to the two fourth pulleys via a transmission belt; a control cam is coaxially fixedly connected to the inside of each of the four control shafts; the two control cams on the same side are respectively aligned with the positions of the two connecting slides.
[0010] Optionally, the top surface of the screen is fixedly connected to multiple sets of elastic metal sheets in a rectangular array; each set of elastic metal sheets has a flexible striking block fixedly connected to its top surface; the flexible striking block is a rectangular block structure made of rubber.
[0011] Optionally, the bottom end face of the screen is fixedly connected to four mounting columns in a rectangular array; the bottom end faces of the two connecting slides are symmetrically fixedly connected to two fixing plates; the four fixing plates are respectively aligned with the positions of the four mounting columns; each of the four fixing plates is threaded with a locking bolt; the ends of the four locking bolts are respectively threaded into the four mounting columns; the outside of the mounting frame is provided with four disassembly slots in a rectangular array; the four locking bolts are respectively set in the four disassembly slots.
[0012] Beneficial effects
[0013] During use, this invention starts the drive motor, which then drives the control cam to rotate through a series of transmissions. As the control cam rotates, it pushes the connecting slide plate to move, causing the screen to move upward. When the control cam stops pushing the connecting slide plate, the slide plate falls under its own weight, causing the screen to vibrate periodically. This breaks up the agglomerated plastic particles, allowing them to form a thin, dispersed flow layer on the screen. This enables the plastic particles to be dried and dehumidified more evenly, effectively improving the practicality of the high-efficiency drying and dehumidifying device.
[0014] During the vibration of the screen, the elastic metal sheet will generate high-frequency oscillation due to resonance. As the elastic metal sheet oscillates at high frequency, it will drive the flexible striking block to periodically tap the screen frame, which can shake down the plastic particles stuck in the gaps of the frame. At the same time, if the flexible striking block touches the material layer, it will gently pat the damp or clump-like plastic particles, causing the clumps to disperse and further making the plastic particles spread more evenly, effectively improving the convenience of the high-efficiency drying and dehumidification device.

[0032] The two control shafts 108 on the left are coaxially fixedly connected to a third pulley 110 on the outside; the two control shafts 108 on the right are coaxially fixedly connected to a fourth pulley 111 on the outside; the two third pulleys 110 are respectively connected to the two fourth pulleys 111 via transmission belts; the inner sides of the four control shafts 108 are coaxially fixedly connected to a control cam 121; the two control cams 121 on the same side are respectively aligned with the positions of the two connecting slide plates 112.
[0033] The top surface of the screen 114 is fixedly connected to multiple sets of elastic metal sheets 118 in a rectangular array; the top surface of each set of elastic metal sheets 118 is fixedly connected to a flexible striking block 119; the flexible striking block 119 is a rectangular block structure made of rubber.
[0034] The specific usage and function of this embodiment are as follows: When drying and dehumidifying plastic particles, the plastic particles are placed on the screen 114, and then the hot air fan 113 is started to dry and dehumidify the plastic particles placed on the screen 114. The mounting frame 1 is supported by the support column 101. During the drying and dehumidification process, the drive motor 103 is started, causing the drive motor 103 to drive the first bevel gear 104 to rotate.

During the vibration of the screen 114, the elastic metal sheet 118 will oscillate at high frequency due to resonance. As the elastic metal sheet 118 oscillates at high frequency, it will drive the flexible striking block 119 to periodically tap the frame of the screen 114.
