[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-5 As shown, a short roller pre-pressing device for substrate glass includes an arched support platform 1, a worktable 2 on the arched support platform 1, and a placement groove 3 for placing short rollers 9 on the worktable 2. The device also includes a pre-pressing component for pre-pressing the short rollers 9, a detection component for detecting the pressure, and a lifting component for pushing the short rollers 9 upward. A support frame 10 is fixedly connected to the arched support platform 1, and the pre-pressing component is fitted onto the support frame 10. The output end of the pre-pressing component is located above the worktable 2, facilitating the pre-pressing component to compress the short rollers 9 placed on the worktable 2.

[0025] The short roller 9 includes a roller shaft 901. One end of the roller shaft 901 is fixedly connected to a through rod 905. Two sets of baffles 903 are slidably sleeved on the through rod 905. An asbestos cylinder 902, which is made of multiple stacked asbestos sheets and has a certain thickness, is pressed between the two sets of baffles 903. The asbestos cylinder 902 is slidably sleeved on the through rod 905. The through rod 905 is used to limit the position of the baffles 903 and the asbestos cylinder 902. The diameter of the baffles 903 is slightly smaller than the diameter of the asbestos cylinder 902 to ensure that the baffles 903 do not directly contact the molten glass when the asbestos cylinder 902 is in use. The end of the through rod 905 away from the roller shaft 901 is threadedly connected to a locking nut 904 that cooperates with the baffles 903. The locking nut 904 is used to maintain the relative position of the two sets of baffles 903 and the asbestos cylinder 902 to maintain the density of the asbestos cylinder 902.

[0026] The detection assembly comprises a detection groove 4 opened on the workbench 2, and a supporting plate 5 is arranged in the detection groove 4 in a matched mode. The supporting plate 5 is arranged in a U shape, and the position of the supporting plate 5 corresponds to the position of the placing groove 3, so that the groove on the supporting plate 5 corresponds to the placing groove 3, and thus the staff can place the short roller 9 on the supporting plate 5. A plurality of springs 6 are arranged in a matched mode between the supporting plate 5 and the detection groove 4, so that the supporting plate 5 can move under the action of the pre-pressing assembly. The detection groove 4 is fixedly connected with a laser range finder 7 for detecting the distance between the bottom of the detection groove 4 and the supporting plate 5. When the laser range finder 7 detects that the distance between the bottom of the detection groove 4 and the supporting plate 5 is equal to a specified value, the pre-pressing assembly stops pressing the short roller 9, so as to avoid deformation and rupture of the asbestos cylinder 902 due to too large pressure.

[0027] In some specific embodiments, in order to facilitate the staff to take away the short roller 9, the lifting assembly comprises an electric telescopic rod 15 fixedly connected with the bottom of the arched supporting table 1, and the electric telescopic rod 15 is located directly below the placing groove 3. The output end of the electric telescopic rod 15 is fixedly connected with a limiting block 18, and a limiting groove for limiting the lower end of the short roller 9 is opened on the limiting block 18. The limiting groove limits the lower end of the short roller 9 to ensure the stability of the asbestos cylinder 902 during the pre-pressing process. The arched supporting table 1 is fixedly connected with a limiting support 8 in the middle, and the limiting support 8 is located directly below the placing groove 3. The limiting support 8 limits the middle of the short roller 9 to ensure the stability of the asbestos cylinder 902 during the pre-pressing process. When the pre-pressing operation of the asbestos cylinder 902 is completed, the electric telescopic rod 15 extends, pushes the limiting block 18 to move upwards, and the limiting block 18 drives the short roller 9 to move upwards, so that the short roller 9 is lifted along the placing groove 3, thereby facilitating the staff to take away the short roller 9.

[0028] In some specific embodiments, in order to realize the pre-pressing of the asbestos cylinder 902, the pre-pressing assembly comprises a hydraulic telescopic rod 11 fixedly connected to the support frame 10, the output end of the hydraulic telescopic rod 11 is fixedly connected with a push plate 12, the two sides of the push plate 12 are fixedly connected with support blocks 13, the end of the support blocks 13 away from the push plate 12 is fixedly connected with a pressing plate 14, and the bottom of the pressing plate 14 is provided with an embedded groove 19 with the same size as the blocking piece 903. When the asbestos cylinder 902 is pre-pressed, the embedded groove 19 is used to accommodate the blocking piece 903, so that the asbestos cylinder 902 is uniformly stressed, and the middle of the pressing plate 14 is provided with a mounting hole 16 penetrating through the pressing plate 14 and matched with the locking nut 904. During the pre-pressing of the asbestos cylinder 902, the penetrating rod 905 will protrude from the inside of the mounting hole 16, and the locking nut 904 can be mounted on the penetrating rod 905 through the mounting hole 16. The laser range finder 7 is electrically connected with the hydraulic telescopic rod 11, when the laser range finder 7 detects that the distance between the bottom of the detection groove 4 and the support plate 5 is equal to the specified value, the hydraulic telescopic rod 11 stops extruding the asbestos cylinder 902, so as to avoid the deformation and rupture of the asbestos cylinder 902.

[0029] In some specific embodiments, in order to ensure the stability of the push plate 12, the support block 13 and the pressing plate 14 during movement, a guide rod 17 is fixedly connected between the support frame 10 and the workbench top 2, and the push plate 12, the support block 13 and the pressing plate 14 are all slidingly sleeved on the guide rod 17. When the hydraulic telescopic rod 11 drives the push plate 12, the support block 13 and the pressing plate 14 to move downward, the push plate 12, the support block 13 and the pressing plate 14 will move along the guide rod 17, so as to ensure the stability of the push plate 12, the support block 13 and the pressing plate 14 during movement.

[0030] In order to facilitate the understanding of the embodiment of the present scheme by those skilled in the art, the working principle of the embodiment of the present scheme will be described in combination with a specific application scenario:

[0031] In use, the assembled short roller 9 is inserted into the placement groove 3, so that one group of blocking pieces 903 of the short roller 9 is attached to the support plate 5, and the lower end of the short roller 9 passes through the limiting support 8 and contacts the limiting groove on the limiting block 18, and the stability of the short roller 9 is maintained through the limiting groove and the limiting support 8;

[0032] After the short roller 9 is placed, the hydraulic telescopic rod 11 is extended, the push plate 12, the supporting block 13 and the pressing plate 14 are driven to move downwards, the pressing plate 14 pre-presses the asbestos cylinder 902, at this time, the baffle 903 at the upper end of the short roller 9 is embedded in the embedded groove 19, so that the pressing plate 14 can extrude the baffle 903 and the asbestos cylinder 902 at the same time, thereby ensuring that the asbestos cylinder 902 is uniformly stressed, when the laser range finder 7 detects that the distance between the bottom of the detection groove 4 and the supporting plate 5 is equal to the specified value, it indicates that the asbestos cylinder 902 is extruded by sufficient strength, that is, the asbestos cylinder 902 can be stopped, the state of the hydraulic telescopic rod 11 can be changed in time through the laser range finder 7, that is, the asbestos cylinder 902 of different thicknesses can be pre-pressed, and the compression effect can be ensured, the thick asbestos cylinder 902 is prevented from being deformed and broken due to excessive pressure, thereby improving the practicability. When the pre-pressing operation is stopped, the penetrating rod 905 extends from the mounting hole 16, the locking nut 904 is mounted on the penetrating rod 905 through the mounting hole 16, the extrusion force of the baffle 903 on the asbestos cylinder 902 is maintained through the locking nut 904, thereby maintaining the density of the asbestos cylinder 902, ensuring that the asbestos cylinder 902 has sufficient hardness during subsequent use, and the hydraulic telescopic rod 11 is reset, thereby completing the pre-pressing operation of the asbestos cylinder 902.

[0033] When the pre-pressing operation is completed, the electric telescopic rod 15 is extended, the limiting block 18 is pushed upwards, the limiting block 18 drives the short roller 9 to move upwards, so that the short roller 9 is lifted along the placing groove 3, thereby facilitating the worker to take away the short roller 9.

[0034] The above describes one embodiment of the present application in detail, but the content described is only a preferred embodiment of the present application, and cannot be considered as limiting the scope of the present application. Any equivalent changes and improvements made according to the scope of the present application should still belong to the patent coverage range of the present application.
