Description

Technical Field

[0001] The invention belongs to the technical field of sandwich mesh detection, and in particular relates to a method for measuring the bonding strength of a sandwich mesh. Background Art

[0002] Sandwich mesh is a new type of pure fabric material, woven by a warp knitting machine, with excellent breathability, elasticity and support. This fabric is usually composed of two layers of polyester silk, the upper and lower silk, and the middle connecting silk is polyester monofilament. The structure of sandwich mesh is similar to the Western sandwich, hence the name. Its three-dimensional mesh structure makes it known as a breathable mesh with good breathability and moderate adjustment ability. In addition, sandwich mesh is widely used in mattresses, pillows, car seat cushions and other fields. Due to its unique structure and performance, it provides these products with good elasticity and permeability.

[0003] When testing the adhesion between each layer of the sandwich mesh, the existing testing equipment needs to manually fix the layer to be pasted and the equipment during use, which is complicated and troublesome to operate. After the test is completed, the clamping structure needs to be loosened again and new testing materials need to be replaced, which is not conducive to improving the testing efficiency. In addition, during the testing process, due to the large pulling force, the clamping position is prone to relative sliding, which may cause inaccurate test data and affect the test results.

[0061] Embodiment 3:

[0062] The difference between the above embodiment and this embodiment is that: Figure 5 , pictures and Figure 7As shown, a guide wheel 2041 is installed on the top of the push rod 204, and the guide wheel 2041 is slidably connected to the guide plate 2051. A slide plate 2042 is installed at the connection between the push rod 204 and the connecting rod 2043. A return spring 2044 is sleeved on the connecting rod 2043. One end of the return spring 2044 is mutually clamped with the bottom of the slide plate 2042, and the other end of the return spring 2044 is mutually clamped with the inner cavity of the locking cover 201. In a specific embodiment, a plurality of pairs of protrusions 2046 are provided at the bottom of the pressing plate 2045, and a plurality of pairs of grooves 2047 are provided on the clamping cavity 203, and the grooves 2047 and the protrusions 2046 correspond to each other. When the locking cover 201 moves, the push rod 204 and the guide wheel 2041 on the locking cover 201 slide on the guide plate 2051, and through the guiding effect of the ramp 2053, the push rod 204 moves to the locking track 2052, and then the locking track 2052 drives the push rod 204 to slide downward, and the push rod 204 drives the internal slide plate 2042 to slide, and the slide plate 2042 can squeeze the reset spring 2044, and the compressed reset spring 2044 is convenient for later reset, and the push rod 204 drives the pressure plate 2045 and the connecting rod 2043 to move downward, and the pressure plate 2045 corresponds to the bottom of the clamping cavity 203, and the pressure plate 2045 moves downward to fix the end of the adhesive layer 4011, and the protrusion 2046 on the pressure plate 2045 corresponds to the groove 2047 at the bottom, thereby improving the structural strength of the connection.

[0063] like Figure 7 and Figure 8As shown, further, a synchronous bracket 3042 is installed at the center of the pressure plate 2045, and a rotating shaft 3041 is rotatably installed inside the synchronous bracket 3042. One end of the rotating shaft 3041 is connected to the rolling roller 304, and the other end of the rotating shaft 3041 is installed with a rotating disk 3031, and the rotating disk 3031 is connected to the rocker arm 303.

After the turntable 3031 rotates, the rocker arm 303 on the turntable 3031 can rotate, and the top of the rocker arm 303 slides on the bottom of the flat plate 3023, and the height of the top of the rocker arm 303 becomes higher, thereby driving the flat plate 3023 to move upward, and the flat plate 3023 drives the partition 3022 to slide upward, and the partition 3022 drives the positioning rod 301 to move upward, and the positioning rod 301 is inserted into the positioning hole 3013, completing the overall locking operation of the equipment, so that the equipment stops detection. In addition, during the sliding of the positioning rod 301 , the extrusion spring 3021 is stretched by the baffle 302 , so that the resetting operation can be performed later conveniently by the extrusion spring 3021 .

[0064] The implementation principle of the method for measuring the bonding strength of a sandwich mesh in this embodiment is as follows:

[0065] The sandwich mesh 400 to be measured is installed on the double-station processing table 102 inside the support unit 100 to facilitate the subsequent improvement of measurement efficiency. The bottom layer 401 at the bottom of the sandwich mesh 400 is placed on the processing table 102, and the outer side of the bottom layer 401 is bent and inserted into the gap of the L-shaped plate 1021. Then the operator rotates the locking bolt 1023, and the clamping plate 1022 is driven by the locking bolt 1023 to start moving. The clamping plate 1022 and the side wall of the L-shaped plate 1021 are pressed against each other, thereby achieving the purpose of clamping the bottom layer 401.

[0066] Next, the adhesive layer 4011 at one end is wound around the guide roller 2021, and the end of the adhesive layer 4011 is inserted into the clamping cavity 203 inside the notch 2031. The locking cover 201 is then pulled and moved by the testing machine to remove the adhesive layer 4011 and the bottom layer 401, and then the bonding strength is measured. The detection principle of the testing machine is the existing technology and will not be repeated here.

[0067] When the locking cover 201 moves, the limiting block 2013 of the side wall slides on the limiting rod 2014. Through the guiding effect of the limiting rod 2014, it is ensured that the locking cover 201 can only slide horizontally, thereby achieving the purpose of limiting.

[0068] When the locking cover 201 moves, the push rod 204 and the guide wheel 2041 on the locking cover 201 slide on the guide plate 2051, and through the guiding effect of the ramp 2053, the push rod 204 moves to the locking track 2052, and then the locking track 2052 drives the push rod 204 to slide downward, and the push rod 204 drives the internal slide plate 2042 to slide, and the slide plate 2042 can squeeze the return spring 2044, and the compressed return spring 2044 is convenient for later reset, and the push rod 204 drives the pressure plate 2045 and the connecting rod 2043 to move downward, and the pressure plate 2045 corresponds to the bottom of the clamping cavity 203, and the pressure plate 2045 moves downward to fix the end of the adhesive layer 4011, and the protrusion 2046 on the pressure plate 2045 corresponds to the groove 2047 at the bottom, thereby improving the structural strength of the connection.

[0069] When the measurement is completed, the push rod 204 slides into the guide plate 2051 through the slope 2053, and the reset operation is performed by the reset spring 2044 to unlock the clamping unit 200.

[0070] During the movement of the locking cover 201, when the adhesive layer 4011 in the locking cover 201 slides, the rolling roller 304 adheres to the adhesive layer 4011, and the movement of the adhesive layer 4011 drives the rolling roller 304 to rotate on the synchronous bracket 3042, and the rolling roller 304 drives the rotating shaft 3041 and the turntable 3031 to rotate. After the turntable 3031 rotates, the rocker arm 303 on the turntable 3031 can rotate, and the top of the rocker arm 303 slides on the bottom of the flat plate 3023, and the height of the top of the rocker arm 303 becomes higher, thereby driving the flat plate 3023 to move upward, and the flat plate 3023 drives the partition 3022 to slide upward, and the partition 3022 drives the positioning rod 301 to move upward, and the positioning rod 301 is inserted into the positioning hole 3013, completing the overall locking operation of the equipment, so that the equipment stops detection. In addition, during the sliding of the positioning rod 301 , the extrusion spring 3021 is stretched by the baffle 302 , so that the resetting operation can be performed later conveniently by the extrusion spring 3021 .
