Technical Field

[0001] The utility model relates to the technical field related to heat resistance testing of synthetic stone heating platforms, in particular to a heat resistance testing device for synthetic stone heating platforms. Background Art

[0002] Since natural marble is a non-renewable resource, and due to technical and human factors, many marble mines in my country have serious waste of resources. Many mines have been razed to the ground by crazy mining. Synthetic stone can make the most of natural marble blocks. Therefore, the use of synthetic stone is a trend of future development. After the production of synthetic stone slabs is completed, they need to be subjected to heat resistance testing to determine whether the heat resistance of the synthetic stone meets the requirements.

[0003] The existing synthetic stone heating platform heat resistance test platform has imperfect functions. When conducting a heating test on the synthetic stone heating platform, the synthetic stone of the synthetic stone heating platform can only be fixed in a designated position. Since the temperature of each area in the heating chamber will deviate, the synthetic stone will be heated unevenly at different positions, and it cannot be guaranteed that the synthetic stone will be heated sufficiently and evenly, which will easily cause deviations in the test results and low test accuracy.

DETAILED DESCRIPTION

[0023] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

A number of connecting plates 11 are fixedly mounted on the disc 4. A connecting shaft 12 is rotatably mounted on each connecting plate 11, and a first fixed plate 13 is fixedly mounted on one end of the connecting shaft 12. Slide rods 14 are fixedly mounted on both sides of the first fixed plate 13. The two slide rods 14 are fixedly mounted with the same second fixed plate 15 at one end away from the first fixed plate 13 on the same side. A clamping assembly 16 is provided on the second fixed plate 15, and a heating plate 17 is fixedly mounted in the heating chamber 1.

[0025] Among them, the rotating assembly 7 includes a second bevel gear 71 fixedly mounted on the top of the rotating shaft 6, the bottom end of the sleeve 5 extends into the heating chamber 1 and is fixedly mounted with a gear disk 72, and the top end of the sleeve 5 is fixedly mounted with a third bevel gear 73. The second bevel gear 71 and the third bevel gear 73 are symmetrically distributed and are both engaged with the first bevel gear 10. A helical gear 74 engaged with the gear disk 72 is fixedly mounted on the other end of the connecting shaft 12.

[0026] In detail, the reduction motor 8 drives the rotating shaft 9 and the first bevel gear 10 to rotate. The rotation of the first bevel gear 10 drives the rotating shaft 6 and the disc 4 to rotate through the second bevel gear 71. The rotation of the disc 4 can drive the synthetic stone fixed on the first fixed plate 13 by the clamping assembly 16 to rotate with the rotating shaft 6 as the axis. When the first bevel gear 10 rotates, it will drive the sleeve 5 and the toothed disc 72 to rotate through the third bevel gear 73. The rotation of the toothed disc 72 drives the helical gear 74 and the connecting shaft 12 to rotate. The rotation of the connecting shaft 12 can drive the synthetic stone fixed on the first fixed plate 13 by the clamping assembly 16. The synthetic stone flips around the connecting shaft 12, so that through the rotation of the reduction motor 8, the synthetic stone can perform circular motion around the rotating shaft 6 and flip around the connecting shaft 12 at the same time. Under the heating action of the heating plate 17, all surfaces of the synthetic stone are heated evenly, which solves the problem of uneven and insufficient heating of the synthetic stone in the heat resistance test and improves the accuracy of the test; by setting up a number of clamping components 16 and connecting shafts 12, a variety of synthetic stones of different types and sizes can be heated at the same time, saving time, reducing energy consumption, and greatly improving work efficiency.

[0027] Among them, the clamping assembly 16 includes a threaded rod 161 rotatably mounted on the second fixed plate 15 on the same side, one end of the threaded rod 161 extends to the outside of the second fixed plate 15 on the same side and is fixedly mounted with a knob, and the other end of the threaded rod 161 is threadedly mounted with a sleeve 162, and a clamping plate 163 is fixedly mounted on the sleeve 162. Turning the knob drives the threaded rod 161 to rotate, and the threaded rod 161 rotates to cooperate with the sliding rod 14 to drive the sleeve 162 and the clamping plate 163 to move toward the side close to the first fixed plate 13, thereby cooperating with the first fixed plate 13 to clamp and fix the synthetic stone placed between the first fixed plate 13 and the clamping plate 163, ensuring the stability of the synthetic stone during rotation and flipping. The structure is simple and easy to use.

[0028] The clamping plate 163 slides on the outer surfaces of the two slide bars 14 , and the slide bars 14 can guide and limit the movement of the clamping plate 163 and the sleeve 162 to prevent the clamping plate 163 and the sleeve 162 from being offset and rotated during the movement.

[0029] Among them, a support rod 18 is fixedly installed on each connecting plate 11, and the bottom end of the support rod 18 is fixedly connected to the disc 4. By setting the support rod 18, the support rod 18, the connecting plate 11 and the disc 4 form a stable triangular structure to ensure the stability of the connecting plate 11 and the connecting shaft 12 during rotation.

[0030] Among them, a transparent observation window 19 is opened on the chamber door 2 to facilitate the operator to observe the heating status of the synthetic stone in real time.

[0031] A pressure relief hole 20 is provided on the top of the heating chamber 1 and a pressure relief valve is provided in the pressure relief hole 20 . By providing the pressure relief hole 20 and the pressure relief valve, the pressure in the heating chamber 1 can be easily regulated.

[0032] During operation, the synthetic stone to be heated and tested is placed between the first fixing plate 13 and the clamping plate 163, and then the knob is turned to drive the threaded rod 161 to rotate. The threaded rod 161 rotates in conjunction with the sliding rod 14 to drive the sleeve 162 and the clamping plate 163 to move toward the side close to the first fixing plate 13, thereby cooperating with the first fixing plate 13 to clamp and fix the synthetic stone placed between the first fixing plate 13 and the clamping plate 163, ensuring the stability of the synthetic stone during the rotation and flipping process;

[0033] After the synthetic stone is fixed, the reduction motor 8 is started, and the reduction motor 8 drives the rotating shaft 9 and the first bevel gear 10 to rotate. The rotation of the first bevel gear 10 drives the rotating shaft 6 and the disc 4 to rotate through the second bevel gear 71. The rotation of the disc 4 can drive the synthetic stone fixed on the first fixed plate 13 to rotate with the rotating shaft 6 as the axis. When the first bevel gear 10 rotates, it will drive the sleeve 5 and the gear plate 72 to rotate through the third bevel gear 73. The rotation of the gear plate 72 drives the helical gear 74 and the connecting shaft 12 to rotate. The rotation of the connecting shaft 12 can drive the synthetic stone fixed on the first fixed plate 13 to flip with the connecting shaft 12 as the axis. Therefore, through the rotation of the reduction motor 8, the synthetic stone can perform circular motion with the rotating shaft 6 as the axis and flip with the connecting shaft 12 as the axis. Under the heating action of the heating plate 17, all surfaces of the synthetic stone are evenly heated, which solves the problem of uneven and insufficient heating of the synthetic stone in the heat resistance test and improves the accuracy of the test.
