Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic parts drying and conveying, specifically a precision plastic parts circulating drying and conveying equipment. Background Technology
[0002] Precision plastic parts circulating drying and conveying equipment is an automated drying and conveying system specifically designed for the production process of precision plastic products. Through precise temperature control, circulating conveying, and efficient drying technologies, it ensures that plastic parts are quickly dehydrated or desolventized after processing, while avoiding problems such as deformation and contamination. It is one of the key pieces of equipment in the field of precision manufacturing.
[0003] The thickness and size variations of precision plastic parts directly alter their heat transfer efficiency and moisture content. Existing technologies struggle to identify workpiece thickness and size, and adjust temperature and drying time accordingly. This makes it difficult to ensure consistent drying quality, leading to workpiece damage and reduced energy efficiency. During drying, trace amounts of moisture may remain on the workpiece surface, easily forming a sticky film upon heating. This film tends to adhere to metal or ordinary rubber conveyor belts, and separation may cause scratches and deformation. Existing technologies struggle to reduce the risk of workpiece adhesion to the conveyor belt while simultaneously minimizing surface damage from friction. Furthermore, the accumulation of impurities masks the low surface energy of the anti-stick layer, actually increasing the risk of workpiece adhesion. Existing technologies also struggle to periodically blow away dust from the anti-stick layer, limiting their practicality. Utility Model Content

[0033] The working principle of a precision plastic parts circulating drying and conveying equipment based on the above is as follows:
[0034] First, when using this device, place it in the work area, and then connect it to an external power source to provide the power required for its operation.
[0035] Second, the operator places the precision plastic part on the conveyor 1 for transport. The initial distance between the precision plastic part and the conveyor 1 is detected by a second laser rangefinder 312. When the initial distance changes, the second laser rangefinder 312 sends an electrical signal to a timer 313, causing the timer 313 to start working. The conveyor 1 then continues to transport the precision plastic part at a constant speed. When the distance between the second laser rangefinder 312 and the conveyor 1 returns to its initial distance, the second laser rangefinder 312 sends an electrical signal to the timer 313, causing the timer 313 to stop working. The operator observes the time of the timer 313 and calculates the longitudinal dimension of the precision plastic part based on the time of the timer 313 and the transport speed of the conveyor 1. The final dimension of the precision plastic part is calculated by subtracting the detection data from the second laser rangefinder 312 from the initial distance between the second laser rangefinder 312 and the conveyor 1. The thickness of the plastic part is measured, and then the conveyor 1 transports the precision plastic part back. The first cylinder 33 is activated, which drives the first moving block 34 to move downward. The first moving block 34 drives the two sets of sliders 35 to move. The two sets of sliders 35 are connected to the first rotating rod 36 and the second rotating rod 37, which causes the distance between the two sets of moving rods 38 to gradually shorten. The two sets of moving rods 38 cause the distance between the two sets of clamping blocks 39 to gradually shorten. The precision plastic part is clamped by the two sets of clamping blocks 39. The first laser rangefinder 310 is activated to detect the distance between the two sets of clamping blocks 39 and transmits the detection data to an external display screen. The operator judges the lateral dimension of the precision plastic part by the detection data on the external display screen, and adjusts the drying temperature of the dryer 2 by the three sets of dimensions to ensure the stability of drying quality, prevent workpiece damage, and improve energy efficiency.
[0036] Third, during use, the low surface energy and high wear resistance of the anti-stick layer 41 reduce the risk of adhesion between the precision plastic parts and the conveyor 1, while also reducing surface damage caused by friction. When the anti-stick layer 41 needs to be cleaned, the second cylinder 44 is activated, which drives the second moving block 45 to move to the right. The second moving block 45, through its rotational connection with the third rotating rod 46, drives the fourth rotating rod 47 and the fifth rotating rod 48 to rotate. The fifth rotating rod 48, through its rotational connection with the fixed block, drives the sliding plate 49 to move to the right. The sliding plate 49 drives the two sets of fixed rods 410 to move to the right, and the two sets of fixed rods 410 drive the two sets of nozzles 411 to move to the right. The two sets of nozzles 411 deliver external gas to the anti-stick layer 41 to blow away dust, preventing the low surface energy characteristics of the anti-stick layer 41 from being masked and reducing the risk of adhesion between the precision plastic parts and the conveyor 1.
[0037] This utility model provides an improved circulating drying and conveying equipment for precision plastic parts. It includes a detection mechanism 3 that adjusts the drying temperature of the dryer 2 based on the thickness, transverse, and longitudinal dimensions of the precision plastic parts, ensuring stable drying quality, preventing workpiece damage, and improving energy efficiency. A cleaning mechanism 4 utilizes the low surface energy and high wear resistance of the anti-stick layer 41 to reduce the risk of adhesion between the precision plastic parts and the conveying component 1, while also reducing surface damage caused by friction. Furthermore, a nozzle 411 blows dust off the anti-stick layer 41 to prevent its low surface energy characteristics from being masked, further reducing the risk of adhesion of the precision plastic parts.
