Embodiment Construction

[0018] In order to make the purpose and features of the present invention more comprehensible, the specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings.

[0019] Such as Figure 1 to Figure 3 As shown, the heat shrink tube expansion vacuum and outer diameter automatic adjustment device includes: a caliper 41 , a controller 50 , a servo motor 22 , a linear motion guide rail 24 and an aperture adjuster 23 .

[0020] The caliper 41 is installed on the vacuum box 31, and is located between the traction roller 51 and the vacuum box 31, placed on both sides of the expanded product (heat-shrinkable tube) 10, for measuring the expanded product 10 The real-time outer diameter value, and output the measured outer diameter value to the controller 50; the expanded product 10 has a higher roundness under the action of vacuum and internal pressure, and its accurate outer diameter can be measured at this time. ...

Abstract

The invention provides a shrinkable tube expansion vacuum and external diameter automatic adjusting device. The shrinkable tube expansion vacuum and external diameter automatic adjusting device comprises a diameter measurement device, a controller, a servo motor, a linear motion guide rail and an aperture adjuster. The shrinkable tube expansion vacuum and external diameter automatic adjusting device can obtain data according to real time external diameters of products, makes a comparison between the data and a standard external diameter value, controls the servo motor to rotate and further drives the aperture adjuster to act, can automatically controls the vacuum degree inside the vacuum box body of expansion equipment, meanwhile achieves adjustment to difference of pressure inside and outside a product, achieves adjustment to the external diameter of the product, achieves real time and continuous adjustment to the external diameter of the product, and is convenient for intelligent adjustment during an expansion process, thereby improving the product stability and product quality.

Description

technical field [0001] The invention relates to the production field of heat-shrinkable sleeves, in particular to a heat-shrinkable tube expansion vacuum and outer diameter automatic adjustment device and heat-shrinkable tube expansion equipment. Background technique [0002] Expansion is an essential process in the production process of heat shrink tubing. At present, the widely used expansion methods include internal pressure method, vacuum method and internal pressure vacuum combination method. The corresponding expansion methods can be selected according to the size and material of the product, but the internal pressure method and internal pressure vacuum combination method are the most widely used. The pressure difference inside and outside the product at the expansion position inside the expansion vacuum box is the main factor affecting the main quality indicators such as product outer diameter and axial shrinkage rate. Since the smoothness of the product passing thro...
