DETAILED DESCRIPTION

[0030] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] A quality inspection device for silicone products, such as Figure 1-Figure 6 As shown, it includes a chassis 1, a connecting plate 2, a test bench 3, a control panel 4, a tensioning mechanism and a position adjustment mechanism. The chassis 1 is connected to a connecting plate 2 in the middle of the top, the connecting plate 2 is connected to a test bench 3 in the middle of the top, the connecting plate 2 is installed with a control panel 4 on the front side, the test bench 3 is provided with a tensioning mechanism for tensioning the silicone product, and the tensioning mechanism is provided with a position adjustment mechanism.

[0032] like Figure 2-Figure 4 As shown, the tensioning mechanism includes a tensioning shaft 51, a spiral dial 52, a sliding block 53, a pressure sensor 54 and a reduction motor 55. The test bench 3 is provided with eight sliding grooves evenly spaced along the circumferential direction, and the sliding block 53 is slidably connected to the sliding groove. The tensioning shaft 51 is slidably connected inside the top of the sliding block 53, and the tensioning shaft 51 passes through the test bench 3. The sliding block 53 is installed with a pressure sensor 54, and the sensing end of the pressure sensor 54 contacts the sliding block 53. The spiral dial 52 is provided with eight arc grooves evenly spaced along the circumferential direction, and the lower part of the sliding block 53 extends into the arc groove, so that when the spiral dial 52 rotates, the sliding block 53 can be squeezed through the arc groove on it to move outward, and a reduction motor 55 is installed in the chassis 1, and the output shaft of the reduction motor 55 is connected to the spiral dial 52, so that the reduction motor 55 can drive the spiral dial 52 to rotate, and the pressure sensor 54 is electrically connected to the control panel 4.

[0033] When the quality of silicone products needs to be tested, the detection device can be used. When in use, the silicone product is first sleeved on the outside of two opposite tensioning shafts 51. If multiple silicone products need to be tested, multiple silicone products are respectively sleeved on the outside of multiple groups of two opposite tensioning shafts 51. For details, see Figure 6, then the preset value can be input on the control panel 4, and then the reduction motor 55 is controlled to drive the spiral dial 52 to rotate. When the spiral dial 52 rotates, it pushes the multiple sliding blocks 53 away from each other through the arc groove on it. When the sliding block 53 moves, it can push the tensioning shaft 51 to move through the pressure sensor 54. At this time, the two relative tensioning shafts 51 move away from each other, which pushes the silicone product to unfold, so that the silicone product is tensioned, and the pressure applied by the pressure sensor 54 to the tensioning shaft 51 is the tension applied by the tensioning shaft 51 to the silicone product, and the pressure sensor 54 can detect the force applied when pushing the tensioning shaft 51 to move and transmit it to the control panel 4. When the preset value is reached, When the control panel 4 sends a signal to the reduction motor 55, the reduction motor 55 is operated to work in reverse to drive the tensioning shaft 51 to reset. After resetting, the reduction motor 55 is controlled to drive the tensioning shaft 51 to tighten the silicone product. This process is repeated, and the silicone product can be stretched repeatedly, so that the quality of the silicone product can be tested. During the test, multiple silicone products can be tested at the same time, and the overall efficiency is higher. When stretching a single silicone product, the entire silicone product can be directly put on the outside of all the tensioning shafts 51. During stretching, multiple tensioning shafts 51 are stretched away from each other at multiple points to reduce damage to the product structure, thereby ensuring the test results.

[0034] like Figure 2-Figure 4 As shown, the position adjustment mechanism includes a rack 61, a rotating sleeve 62 and a gear 63. The outer side of the tensioning shaft 51 is rotatably connected to the rotating sleeve 62. The silicone product can be sleeved on the outer sides of two opposite rotating sleeves 62. The lower part of the rotating sleeve 62 is connected to the gear 63 through a one-way clutch. Eight racks 61 are evenly spaced along the circumferential direction at the top of the test bench 3. The gear 63 is meshed with the rack 61 so that the rotating sleeve 62 can rotate through the meshing between the gear 63 and the rack 61 when moving.

[0035] When the silicone product is sleeved, it can be sleeved on the rotating sleeve 62. When the tensioning shaft 51 moves outward, it can drive the rotating sleeve 62 to move together. When the rotating sleeve 62 moves, it will drive the gear 63 to move. When the gear 63 moves, it can mesh with the rack 61. At this time, the gear 63 rotates through the rack 61, and will not drive the rotating sleeve 62 to rotate under the action of the one-way clutch. During the resetting process of the tensioning shaft 51, the gear 63 rotates in the opposite direction through the rack 61. At this time, the reverse rotation of the gear 63 can drive the rotating sleeve 62 to rotate. The rotation of the rotating sleeve 62 can drive the silicone product to rotate, thereby adjusting the stretching position of the silicone product to achieve testing of multiple positions of the silicone product, and the test results are more accurate.

[0036] like Figure 5-Figure 8As shown, it also includes a limiting mechanism, which includes a guide wheel 71, a sliding frame 72 and an adjusting screw 73. The guide wheel 71 is slidably connected to the rotating sleeve 62, and the guide wheel 71 can slide up and down along the rotating sleeve 62. The sliding frame 72 is rotatably connected to the rotating sleeve 62. The adjusting screw 73 is threadedly connected in the tensioning shaft 51, and the adjusting screw 73 is rotatably connected to the sliding frame 72. The adjusting screw 73 rotates in the tensioning shaft 51 and can move up and down through the thread, thereby driving the guide wheel 71 to move up and down through the sliding frame 72. A knob is connected to the top of the adjusting screw 73 to facilitate the operation of rotating the adjusting screw 73.

[0037] When the silicone product is sleeved, the silicone product can be sleeved on the guide wheel 71, and the silicone product can be limited by the guide wheel 71 to avoid the position of the silicone product being offset during testing. When the height of the guide wheel 71 needs to be adjusted, the adjusting screw 73 can be rotated to drive the sliding frame 72 to move up and down through the thread, thereby driving the guide wheel 71 to move up and down for adjustment.

[0038] like Figure 9-12 As shown, a cooling mechanism is also included, which includes a cooling frame 81, a water pump 82, a water pump 83 and a water outlet pipe 84. The bottom of the test bench 3 is connected to the cooling frame 81, and the cooling frame 81 is filled with coolant. A water pump 82 is installed in the cooling frame 81, and the liquid outlet end of the water pump 82 is connected to the water pump 83. A U-shaped cooling channel is opened in the tensioning shaft 51, and the head end of the cooling channel is connected to the water pump 83, and the tail end of the cooling channel is connected to the water outlet pipe 84. The water outlet pipe 84 passes through the sliding block 53, so that the water pump 82 can operate to draw the coolant into the water pump 83, and then inject it into the cooling channel through the water pump 83 to cool the tensioning shaft 51. The cooled water can be discharged into the cooling frame 81 through the water outlet pipe 84 to complete the circulation of the coolant.

[0039] When testing silicone products, the water pump 82 can be controlled to operate to inject the coolant in the cooling block into the water guide groove 85 through the water pumping pipe 83, thereby cooling the tensioning shaft 51. The tensioning shaft 51 can cool the silicone product through the heat conduction of the rotating sleeve 62 and the guide wheel 71, thereby achieving the effect of cooling the silicone product and preventing the silicone product from changing its properties due to excessive temperature, thereby affecting the test results. The coolant in the water guide groove 85 will be injected into the cooling frame 81 through the water outlet pipe 84 to achieve the circulation of the coolant.

[0040] like Fig.13 and Fig.14As shown, a covering mechanism is also included, and the covering mechanism includes a shielding cover 91, a guide frame 92, a servo motor 93 and a lifting screw 94. The left and right sides of the chassis 1 are connected to the guide frames 92, and the shielding cover 91 is slidably connected between the guide frames 92 on both sides. Servo motors 93 are installed on the guide frames 92 on both sides, and the output shaft of the servo motor 93 is connected to the lifting screw 94. The lifting screw 94 is threadedly matched with the shielding cover 91, so that the rotation of the lifting screw 94 can drive the shielding cover 91 to move up and down.

[0041] During testing, the servo motor 93 can be controlled to drive the lifting screw 94 to rotate, thereby driving the shielding cover 91 to move downward through the thread, so that the shielding cover 91 covers the silicone product, preventing the silicone product from popping out to the human body when it breaks and causing harm to the human body, thereby protecting the human body.

[0042] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
