DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1-Figure 2 As shown, the utility model provides a tension detection device for an electroforming printing screen, which is used to perform tension detection on a screen body 3, and includes a detection substrate 1 and a tension detector 2. A support net 11 is embedded inside the detection substrate 1, a cushioning portion 12 is provided at the upper end of the support net 11, and a positioning point 121 is provided at the upper end of the cushioning portion 12. The screen body 3 is arranged inside the cushioning portion 12, and the tension detector 2 is located above the screen body 3. The tension detector 2 can be positioned at the four corners of the screen body 3 by the provided positioning points 121, thereby avoiding the problem of inaccurate positioning and measurement of the steel mesh tension meter by manual feeling at present, and thus ensuring that the subsequent detection data is sufficiently accurate.

[0025] In a further embodiment, referring to Figure 1-Figure 2The cushion support portion 12 is rectangular in shape, made of epoxy resin material and coated on the upper end of the support net 11, and eight groups of positioning points 121 are provided, and the distance between each group of positioning points 121 and the four corners of the cushion support portion 12 is the same.

[0026] In this embodiment, by setting the cushioning portion 12 in a rectangular shape, the mesh body 3 is more closely embedded in the cushioning portion 12, thereby achieving the effect of fixing the mesh body 3. At the same time, epoxy resin is coated on the upper end of the supporting mesh 11, so that the positioning points 121 are easier to mark on the epoxy resin material, and the tension tester 2 is positioned by two groups of positioning points 121 at right angles to the cushioning portion 12.

[0027] In a further embodiment, referring to Figure 3-Figure 4 The tension detector 2 includes a counterweight base block 21 and a display head 24. The counterweight base block 21 is placed on the upper end of the tension detector 2, the detection head is installed at the lower end of the counterweight base block 21, and the display head 24 is installed at the upper end of the counterweight base block 21. When the data detected by the detection head is displayed through the display head 24, a storage groove 211 is opened on the side wall of the counterweight base block 21. The storage groove 211 is provided with two groups and is located at the two opposite end surfaces of the counterweight base block 21. A laser calibration component 22 is arranged inside the storage groove 211. The laser calibration component 22 cooperates with the positioning point 121. A transmission component 23 is arranged inside the counterweight base block 21. The transmission component 23 is used to drive the laser component.

[0028] In this embodiment, the laser calibration component 22 is moved out from the storage groove 211 through the transmission mechanism, and then the arranged laser calibration component 22 cooperates with the positioning point 121 to achieve the effect of positioning the tension detector 2.

[0029] In a further embodiment, referring to Figure 3-Figure 4 The transmission assembly 23 includes a transmission rod 231 and a worm gear 234. The transmission rod 231 is rotatably connected inside the counterweight base 21. External threads 232 are provided on the side walls at both ends of the transmission rod 231. A rotating rod 233 is rotatably connected inside each group of storage grooves 211. Two groups of rotating rods 233 are provided. The side walls of the rotating rods 233 are fixedly connected with worm gears 234. The worm gears 234 and the external threads 232 are meshed with each other. Knobs 235 are fixedly connected at both ends of the transmission rod 231.

[0030] In this embodiment, the transmission rod 231 is driven to rotate by rotating the knob 235, and the external thread 232 is driven to rotate by rotating the transmission rod 231. The external thread 232 drives the worm gear 234 to rotate. The worm gear 234 drives the rotating rod 233 to rotate, and the rotating rod 233 provides power for the movement of the laser calibration assembly 22.

[0031] In a further embodiment, referring to Figure 3-Figure 4 The thread directions of the external threads 232 at both ends of the transmission rod 231 are opposite.

[0032] In this embodiment, by setting the thread directions of the two sets of external threads 232 to be opposite, the worm gears 234 at both ends of the transmission rod 231 can be driven to rotate in different directions, thereby facilitating the storage of the movable swing arm 221 in the storage groove 211 .

[0033] In a further embodiment, referring to Figure 3-Figure 5 The laser calibration component 22 includes a movable swing arm 221 and a laser lamp 222. The movable swing arm 221 is fixedly connected to the side wall of the rotating rod 233. The movable swing arm 221 is located inside the storage groove 211. The laser lamp 222 is arranged on the lower end surface of the movable swing arm 221 away from the rotating rod 233.

[0034] In this embodiment, the light emitted by the two groups of laser lights 222 on one side of the storage slot 211 coincides with the positioning points 121 beside the right angles, thereby achieving the effect of positioning the tension detector 2.

[0035] In a further embodiment, referring to Figure 4 A self-reset switch is installed inside the storage groove 211, and four groups of self-reset switch buttons 212 are provided. The side wall of the movable swing arm 221 cooperates with the self-reset switch buttons 212.

[0036] In this embodiment, the movable swing arm 221 moves out from the storage groove 211 and abuts against the self-resetting switch button 212. At this time, the circuit of the laser lamp 222 forms a complete path, thereby turning on the laser lamp 222. When the side wall of the movable swing arm 221 is away from the self-resetting switch button 212, the circuit of the laser lamp 222 is in a disconnected state, and the laser lamp 222 no longer works.

[0037] The working principle of the utility model is as follows: the mesh body 3 is placed inside the cushion support 12, and then the knob 235 is turned to drive the transmission rod 231 to rotate, the transmission rod 231 rotates to drive the external thread 232 to rotate, the external thread 232 rotates to drive the worm gear 234 to rotate, the worm gear 234 rotates to drive the rotating rod 233 to rotate, the rotating rod 233 rotates to drive the movable swing arm 221 to rotate with the rotating rod 233 as the axis, so that the movable swing arm 221 moves out from the storage groove 211, when the side wall of the movable swing arm 221 is tightly abutted against the self-resetting switch button 212 At this time, the circuit of the laser lamp 222 forms a complete path, thereby turning on the laser lamp 222, and then placing the tension detector 2 on the full-scale calibration pad and calibrating the tension detector 2. The calibrated tension detector 2 is transferred to the top of the mesh body 3, so that the light irradiated by the laser lamp 222 coincides with the positioning point 121 at a right angle to the pad support part 12, thereby achieving the effect of positioning the tension detector 2, thereby avoiding the current problem of inaccurate positioning and measurement of the steel mesh tension meter by manual feeling, and thus ensuring that the subsequent detection data is accurate enough.
