Description

Technical Field

[0001] The utility model relates to the technical field of tension controllers, in particular to a tension controller with high-efficiency heat dissipation. Background Art

[0002] The tension controller is a system developed by a single-chip microcomputer or some embedded devices and peripheral circuits. It is a control instrument that can directly set the tension value required to be controlled, and then directly input the signal of the tension sensor as the tension feedback value. After the deviation is obtained through comparison, it is input to the controller such as PID for processing, and finally output to the peripheral actuator for control, ultimately achieving the purpose of minimum deviation and fastest system response. The existing technology has the following problems:

[0003] Because the existing tension controller adopts a sealed shell design, the control panel is in a closed state when in use. However, there are circuit boards of the control panel and the controller inside. Various electronic components are installed on the circuit boards. When used for a long time, the electronic components will release heat, causing the internal temperature to be too high. Heat can only be dissipated by the holes at the bottom of the shell for wiring. The heat dissipation effect is poor, causing the electronic components to work in a high temperature environment for a long time, affecting their service life. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

A filter 1421 is fixedly installed on the side. The filter 1421 is made of a small-aperture mesh surface, which can filter most of the dust and mosquitoes in the air to prevent them from entering the tension controller housing 1 and damaging the controller circuit board 11. The filter 1421 is located on the rear side of the air inlet motor 144. Guide plates 13 are fixedly installed on the left and right sides of the rear end of the bottom of the inner wall of the tension controller housing 1. The guide plates 13 are located on the rear side of the controller circuit board 11, and there is a gap between the left and right opposite ends of the two guide plates 13 and the left and right sides of the inner wall of the controller circuit board 11;

[0022] When the controller circuit board 11 in the tension controller housing 1 is working, the electronic components on it will dissipate heat. The heat dissipation and air outlet mechanism 12 located on the front side of the controller circuit board 11 on the left and right sides of the tension controller housing 1 can cooperate with the air outlet motor 122 in the fixed ring 121 included in the heat dissipation and air outlet mechanism 12 to drive the outlet fan 123 to blow out the heat through the protective net 124. At the same time, the air inlet motor 144 in the fixed ring 141 drives the inlet fan 143 to rotate, so that the external air can be filtered through the filter net 1421 on the filter clamp 142 and blown into from the rear side of the inner cavity of the tension controller housing 1, and two guide plates 13 are used to make the air flow blow from the gaps on the left and right sides of the controller circuit board 11 into the front side of the tension controller housing 1, and from the gap between the two guide plates 13 to the middle of the rear side of the controller circuit board 11, so as to evenly dissipate the heat of the controller circuit board 11, so that air circulation is formed in the inner cavity of the tension controller housing 1, and the heat is quickly dissipated.

[0024] When the filter screen 1421 needs to be cleaned, it is only necessary to directly unplug the filter clip 142 from the fixing ring 141. During installation, the filter clip 142 is directly clamped on the fixing ring 141 until the fixing ring 141 is against the filter screen 1421. At this time, the filter clip 142 will squeeze the semicircular buckle 1414, so that the pressure plate 1413 squeezes the compression spring 1412, and then the filter clip 142 is rotated until the positioning hole 1422 is aligned with the semicircular buckle 1414. The semicircular buckle 1414 can be clamped into the positioning hole 1422 under the rebound pressure of the compression spring 1412 to complete the positioning.

[0025] like Figure 6 As shown, three wire entry holes 15 are evenly opened at the bottom of the tension controller housing 1, which are used to connect the ground wire, live wire and other lines to the controller circuit board 11. Three conical rubber sleeves 151 are evenly fixedly installed at the bottom of the tension controller housing 1 and pass through the three wire entry holes 15. The lines will pass through the conical rubber sleeves 151. Under the action of the small aperture at the lower end of the conical rubber sleeves 151, the wire entry holes 15 are sealed to the greatest extent, thereby preventing dust from entering the tension controller housing 1 through the wire entry holes 15.

[0026] The following is a detailed description of the working principle of the tension controller with efficient heat dissipation.

[0027] like Figure 1-6 As shown, when the controller circuit board 11 in the tension controller housing 1 is working, the electronic components on it will dissipate heat. Through the heat dissipation and air outlet mechanism 12 located on the front side of the controller circuit board 11 arranged on the left and right sides of the tension controller housing 1, the air outlet motor 122 in the fixed ring 121 included in the heat dissipation and air outlet mechanism 12 can drive the outlet fan 123 to blow out the heat through the protective net 124. At the same time, the air inlet motor 144 in the fixed ring 141 drives the inlet fan 143 to rotate, so that the external air can be filtered through the filter net 1421 on the filter clamp 142 and blown into from the rear side of the inner cavity of the tension controller housing 1, and two guide plates 13 are used to make the air flow blow from the gaps on the left and right sides of the controller circuit board 11 into the front side of the tension controller housing 1, and from the gap between the two guide plates 13 to the middle of the rear side of the controller circuit board 11, so as to evenly dissipate the heat of the controller circuit board 11, so that the inner cavity of the tension controller housing 1 forms air circulation and quickly dissipates heat.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
