Description

Technical Field

[0001] The utility model relates to the technical field of silicone product testing, in particular to a high-temperature deformation tester for silicone bibs. Background Art

[0002] Silicone bibs are an item that is worn around the neck during meals, so their quality and safety are of utmost importance. In order to test the quality of the finished silicone bibs, a high temperature deformation test is required to ensure that they will not deform or melt when in contact with hot food.

[0003] Current high-temperature deformation testing equipment usually uses two steps: first, the outer surface of the silicone bib is baked, and then it is stretched and deformed using a tensile instrument. However, there is a problem with this testing method: when the stretching deformation is performed after baking, the outer surface temperature of the silicone bib may cool down, thus affecting the accuracy of the test results. Utility Model Content

[0004] The utility model aims at the technical problems existing in the prior art and provides a high-temperature deformation tester for a silicone bib to solve the problem that the temperature of the outer surface of the silicone bib is easily reduced during the high-temperature test of the silicone bib.

[0005] The utility model solves the above technical problems with the following technical solutions: A high temperature deformation tester for silicone bibs, comprising:

[0006] Constant temperature box;

[0007] A driving member, wherein the driving member is arranged in the constant temperature box;

[0008] The first bearing block and the second bearing block are arranged opposite to each other and are respectively arranged on the driving end of the driving member, wherein the driving member is used to drive the first bearing block and the second bearing block to move in opposite directions respectively;

[0009] Heating component 1, the heating component 1 is arranged on the top of the first bearing block and the second bearing block;

[0010] Heating component 2, the heating component 2 is located above the heating component 1 and is arranged on the bearing block 1 and the bearing block 2;

[0011] A fixing component is located between the heating component 1 and the heating component 2, and is arranged on the supporting block 1 and the supporting block 2, and is used to fix the silicone bib.

[0012] The beneficial effects of the utility model are:

[0013] 1) A heating component 1 and a heating component 2 are arranged on two bearing blocks which can be displaced in opposite or opposite directions to each other, so as to realize rapid heating treatment of the silicone bib, and the heating component 2 is located above the heating component 1. At the same time, the silicone bib is fixed between the heating block 1 and the heating block 2 by means of a fixing component, so that the two sides of the silicone bib can be close to the heating component 1 and the heating component 2 to quickly reach the required high temperature. Subsequently, the bearing block 1 and the bearing block 2 are displaced and pulled apart in opposite directions, thereby stretching the silicone bib being heated to both sides, which not only realizes rapid heating treatment of the silicone bib, but also satisfies the requirement that the silicone bib will not cool down during the stretching process and is continuously heated.

[0014] 2) At the same time, the test method also places the silicone bib for high temperature deformation test in a constant temperature box for testing, which can avoid the interference of the external environment on the test results and further improve the accuracy and reliability of the test.

[0015] On the basis of the above technical solution, the present invention can also be improved as follows.

[0016] Furthermore, two nuts are disposed inside the first bearing block and inside the second bearing block.

[0017] Furthermore, the driving part includes a servo motor, pulley one, pulley two, pulley three, a transmission belt, left and right rotating screws one, and left and right rotating screws two. The servo motor is fixed on one side of the constant temperature box, and the driving end of the servo motor passes through the constant temperature box and extends inside the constant temperature box.

[0018] Furthermore, the pulleys are coaxially fixed on the driving end of the servo motor, the pulley two and the pulley three are located below the pulley one, and are respectively rotatably connected to the side wall of the constant temperature box through a rotating shaft, the transmission belt is sleeved on the outside of the pulley one, the pulley two, and the pulley three, one end of the left and right rotating screw one and one end of the left and right rotating screw two are coaxially fixed on one side of the pulley two and the pulley three, respectively, wherein the other end of the left and right rotating screw one and the other end of the left and right rotating screw two penetrate the nuts respectively, and are rotatably connected to the side wall of the constant temperature box through a rotating shaft.

[0019] The beneficial effect of adopting the above further solution is that when the servo motor drives the first pulley to rotate, since the second pulley and the third pulley are mechanically connected to the first pulley through the transmission belt, the first pulley can drive the second pulley and the third pulley to rotate synchronously in the same direction. The rotations of the second pulley and the third pulley respectively drive the left and right-handed lead screws one and the left and right-handed lead screws two to rotate synchronously in the same direction. Also, since the left and right-handed lead screws one and the left and right-handed lead screws two respectively penetrate through two nuts in the first bearing block and the second bearing block, and through the action relationship between the threads, the first bearing block and the second bearing block can be driven to displace in opposite or opposite directions respectively, generating a force to stretch the silicone bib.

[0020] Further, the first heating assembly includes a first heating tube, a second heating tube, a third heating tube, a fourth heating tube, and a first telescopic rod. The first heating tube is fixed on the top of the first bearing block, the second heating tube is fixed on the top of the second bearing block, the first telescopic rod is fixed between the first bearing block and the second bearing block, and the third heating tube and the fourth heating tube are respectively fixed on both sides of the first telescopic rod.

[0021] The beneficial effect of adopting the above further solution is that by fixing the third heating tube and the fourth heating tube on both sides of the first telescopic rod respectively, it can be ensured that during the stretching process of the silicone bib, the third heating tube and the fourth heating tube also move along with the stretched silicone bib, and the bib being stretched can be heated to prevent the temperature of its outer surface from dropping.

[0022] Further, the second heating assembly includes a fifth heating tube, a sixth heating tube, a seventh heating tube, an eighth heating tube, a second telescopic rod, a first bracket, and a second bracket. The first bracket and the second bracket are respectively fixed on one side of the first bearing block and one side of the second bearing block. The second telescopic rod is fixed between the first bracket and the second bracket. The fifth heating tube, the sixth heating tube, the seventh heating tube, and the eighth heating tube are along the axis of the second telescopic rod and are sequentially distributed at the bottom of the second telescopic rod.

[0023] The beneficial effect of adopting the above further solution is that similarly, by arranging the fifth heating tube, the sixth heating tube, the seventh heating tube, and the eighth heating tube along the axis of the second telescopic rod and sequentially distributing them at the bottom of the second telescopic rod, it can be ensured that during the stretching process of the silicone bib, the fifth heating tube, the sixth heating tube, the seventh heating tube, and the eighth heating tube can also heat the bib being stretched to prevent the temperature of its outer surface from dropping.

[0024] Further, the fixing assembly includes two groups of limiting members. One group of the limiting members includes a limiting plate in the shape of a "匚" and an extension rod. The two extension rods are respectively fixed on the tops of the first bearing block and the second bearing block, and the two limiting plates are respectively fixed at the tops of the two extension rods. A plurality of fastening bolts are screwed on the top of each limiting plate.

[0025] The beneficial effect of adopting the above further solution is that the two sides of the silicone bib are respectively placed in the two limiting plates, and then the fastening bolts are tightened to fix the silicone bib on the limiting plates. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Silicone bibs are an item that is worn around the neck during meals, so their quality and safety are of utmost importance. In order to test the quality of the finished silicone bibs, a high temperature deformation test is required to ensure that they will not deform or melt when in contact with hot food.

[0033] Current high temperature deformation testing equipment usually uses two steps: first, the outer surface of the silicone bib is baked, and then it is stretched and deformed using a tensile instrument. However, this testing method has a problem: when the silicone bib is stretched and deformed after baking, the outer surface temperature may cool down, thereby affecting the accuracy of the test results.
