Description

Technical Field

[0001] The invention relates to the technical field of drying ovens, in particular to a constant temperature drying oven for detecting raw materials used in battery tank production. Background Art

[0002] A battery container refers to a device that acts as a container and protects the battery. It must be resistant to corrosion by sulfuric acid. In addition, it must meet some special requirements in use, such as strength, vibration resistance, impact resistance, and high and low temperature resistance. The existing battery container needs to test its raw materials during production to ensure that the materials can meet production requirements. When testing its raw materials, the materials need to be dried. Otherwise, the residual moisture in the materials will not only affect the size and weight, resulting in inaccurate test results, but also the moisture may react with certain chemical substances in the test environment, affecting the test results. Therefore, it must be dried. When the battery container is dried in the constant temperature drying oven for production under the existing technology, it is generally placed in a tray for support. Although this method is simple, even if a through hole is opened on the tray, the contact area between the raw material and the tray is large, which affects the drying efficiency and quality of the raw material and is prone to uneven drying. Although some constant temperature drying ovens for battery container production can hang the raw materials for drying to reduce the contact area with the support, they need to be operated one by one using a clamp, which is cumbersome and inconvenient to operate.

[0016] 1. A load-bearing positioning frame is arranged inside the drying box body, and a load-bearing matching sleeve is arranged on the load-bearing positioning frame. When the raw materials are dried, the load-bearing matching sleeve is in close contact with the raw materials, and a negative pressure for adsorbing the raw materials can be formed in the load-bearing matching sleeve, so that the raw materials can be lifted, and the contact area between the raw materials and the supporting member can be reduced, so that the raw materials can be dried more evenly, which can not only improve the quality of drying, but also multiple adsorption operations can be performed simultaneously, which is convenient for the staff.

Under the action of the sealed closing door, the movable matching strip will be pushed to move. As the movable matching strip moves, it will drive the matching movable carrier block to move upward. As the matching movable carrier block moves, it will drive the bearing movable plate to move, and then the bearing matching sleeve on the bearing movable plate will move to make it contact with the upper surface of the raw material. Then, as the matching movable carrier block moves upward, negative pressure can be formed in the bearing matching sleeve to adsorb and fix the raw material.

[0018] 3. In addition, after negative pressure is formed in the bearing matching sleeve to adsorb and support the raw materials, as the movable matching strip moves, the movable bearing block will be driven downward under the action of the pull-down drive frame, and as the movable bearing block moves downward, the bearing contact plate will also be driven downward, thereby separating the bearing contact plate from the raw materials, thereby completely exposing the lower end surface of the raw materials, so that the raw materials are in a suspended state, which is convenient for drying.

[0041] A plug-in carrier rod 51 is fixedly provided on the mating movable bar 5, and a mating plug plate 52 is fixedly provided on the lower end of the plug-in carrier rod 51. The plug-in carrier rod 51 passes through the plug-in connecting hole 43 and is inserted in the load-bearing mating sleeve 42. The mating plug plate 52 is inserted in the load-bearing mating sleeve 42, and the mating plug plate 52 is flush with the lower end surface of the load-bearing mating sleeve 42. A load-bearing protrusion 53 is fixedly provided at one end of the mating movable bar 5, and a connecting rod 54 is fixedly provided on the load-bearing protrusion 53. The connecting rod 54 is inserted in the connecting through hole 383.

[0042] A movable supporting block 6 is installed in the drying chamber 11, and a plug-in connecting column 61 is fixedly provided on one side of the movable supporting block 6. The plug-in connecting column 61 is plugged into the stabilizing channel 271 and contacts the inner wall of the stabilizing channel 271, and a plug-in matching vertical rod 62 is fixedly provided on the upper end of the movable supporting block 6, and the plug-in matching vertical rod 62 is plugged into the matching movable hole 17.

[0043] A matching carrier strip 63 is fixedly arranged on the plug-in matching upright bar 62 , a supporting upright column 64 is fixedly arranged on the matching carrier strip 63 , and a bearing contact plate 65 is fixedly arranged on the supporting upright column 64 .

[0044] When the raw material is dried, it is placed in the bearing positioning groove 14, and then the sealed closing door 12 is closed. During the closing process, the sealed closing door 12 will contact the contact matching block 22, and then the contact matching block 22 will be pushed to move under the action of the sealed closing door 12. As the contact matching block 22 moves, it will drive the movable matching strip 2 to move. As the movable matching strip 2 moves, the driving connecting rod 26 will push the matching movable carrier 3 to move upward. As the matching movable carrier 3 moves upward, the push-up carrier rod 35 will contact the matching inclined surface 47, so that when the push-up carrier rod 35 contacts the matching inclined surface 47, the push-up carrier rod 35 will contact the matching inclined surface 47. 7, the bearing movable plate 4 will be driven to move, and then the bearing matching sleeve 42 will be driven to move out of the receiving groove 15, so that the lower end surface of the bearing matching sleeve 42 is pressed on the raw material. Before this, the bearing matching sleeve 42 is at both ends of the raw material, which is convenient for placing the raw material. When the pushing load rod 35 contacts the limit contact surface 48, the bearing movable plate 4 will no longer move. At this time, the connecting convex plate 382 moves up to contact the lower end surface of the bearing convex frame 53. In this way, as the matching movable load block 3 continues to move upward, the bearing convex frame 53 will be driven to move upward under the action of the connecting convex plate 382, ​​and then the matching movable bar 5 will be driven to move upward. As the movable matching strip 5 moves upward, the matching plug plate 52 will also be driven to move upward, thereby forming a negative pressure in the bearing matching sleeve 42, and the raw material can be adsorbed and fixed under the action of the negative pressure. After the negative pressure is generated in the bearing matching sleeve 42, the plug-in connecting column 61 will also be in the pull-down channel 281. As the movable matching strip plate 2 continues to move, the movable bearing block 6 will be moved downward under the action of the pull-down channel 281, thereby driving the bearing contact plate 65 to move downward, so that the bearing contact plate 65 is no longer in contact with the raw material, so that its lower end surface is completely exposed, so that it can be in a suspended state. The contact area between it and the support is reduced to the greatest extent, ensuring the drying efficiency and drying quality, and the operation is very convenient. Just place the raw materials in the load-bearing positioning groove 14, and then close the sealed closing door 12. There is no need to adjust them one by one. When the drying is completed, open the sealed closing door 12 to allow the movable matching strip plate 2 to be reset under the action of the first reset spring 24, and then the load-bearing contact plate 65 to be reset and play a supporting role again. At the same time, with the reset of the matching movable carrier block 3, the load-bearing movable plate 4 will also be reset under the action of the second reset spring 451, which is convenient for taking and placing, and is very practical.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
