Description

Technical Field

[0001] The utility model relates to the technical field of dry ice processing, in particular to a dry ice block pressing device which is convenient for replacing molds. Background Art

[0002] Physical properties: White crystals, easy to sublimate at room temperature, high heat of vaporization, can rapidly reduce the surrounding temperature when sublimating under normal pressure, so dry ice will liquefy and even further condense water vapor in the air when sublimating in the air, and the formed water vapor droplets or small ice crystals adhere to the dust in the air to form white smoke that we can see. The crystal structure of dry ice is a simple cubic structure, which belongs to molecular crystals. Single carbon dioxide molecules are located at the vertices and face centers of the cube in different orientations, and accumulate to form dry ice crystals. When processing dry ice, a dry ice briquetting device that is easy to replace the mold is needed to briquette the dry ice material.

[0003] Today's dry ice briquetting equipment can basically meet people's needs, but there are still some problems. The specific problems are as follows:

[0004] 1. It is difficult to replace the lower mold of the dry ice briquetting equipment. When processing dry ice, it is often necessary to press the dry ice into different shapes, which requires replacing different lower molds for processing.

[0005] 2. It is difficult for the dry ice briquetting equipment to position the briquetting when it is lifted or lowered. When the briquetting is lifted or lowered, it may be offset. At the same time, because the lower mold is often replaced, the briquetting must also be replaced. If the briquetting is forgotten to be replaced, forced extrusion will easily cause damage to the lower mold and the briquetting. Utility Model Content

[0006] The utility model aims to provide a dry ice briquetting device which is convenient for replacing molds, so as to solve the defects of the existing dry ice briquetting device that it is difficult to replace the lower mold and to position the briquetting when lifting.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions: a dry ice briquetting device that is convenient for replacing molds, comprising a support leg;

[0008] A supporting structure is installed at the top of the supporting leg, and the supporting structure includes a workbench, a bracket and a top plate. The workbench is installed at the top of the supporting leg, and a bracket is installed at the top of the workbench;

[0009] A top plate is installed at the top of the bracket, a hydraulic cylinder is passed through the top of the top plate, an extrusion block is installed at the bottom of the hydraulic cylinder, a fixing bolt is installed at the top of the extrusion block, a lower mold is installed at the top of the workbench, and positioning structures are installed on both sides of the lower mold and the extrusion block;

[0010] A positioning block is installed at the bottom end of the lower mold, and disassembly structures are installed on both sides of the positioning block. The disassembly structure includes a baffle, a buckle and a first spring. The baffle is installed at the bottom end of the workbench, and a first spring is installed on one side of the baffle.

[0011] When in use, first the hydraulic cylinder works to drive the extrusion block to rise and fall, and the dry ice material is loaded into the lower mold. The extrusion block can be lifted and lowered to extrude the dry ice material and form the dry ice extrusion block. The push plate inside the lower mold can be lifted and lowered, and the push plate and the second spring are elastic. When the extrusion block is pressed down, the push plate will also fall, and when the push plate rises, the extrusion block will also rise to push out the processed dry ice blocks, making it easier to discharge the dry ice blocks. The guide rod can be retracted to prevent the push plate from deviating.

[0012] Furthermore, a buckle is installed on one side of the first spring, and the buckle is symmetrically distributed about the central axis of the workbench. The buckle can fix the positioning block.

[0013] Furthermore, the first spring is in a spiral shape, the first spring and the buckle form an elastic connection, and the first spring is elastic.

[0014] Furthermore, a discharge structure is installed inside the lower mold, and the discharge structure includes a push plate, a guide rod and a second spring. The guide rod is installed at the bottom end of the lower mold, and a push plate is installed on the top of the guide rod. The push plate inside the lower mold can be raised and lowered. The push plate and the second spring are elastic. When the extrusion block is pressed down, the push plate will also drop. When the push plate rises, the extrusion block will also rise, pushing out the dry ice blocks after processing, making it easier to discharge the dry ice blocks. The guide rod can be retracted and can prevent the push plate from deviating.

[0015] Furthermore, a second spring is installed at the bottom end of the push plate, and the second springs are arranged at equal intervals at the bottom end of the push plate, and the second springs are elastic.

[0016] Furthermore, the positioning structure includes a first positioning plate, a second positioning plate, a positioning rod, a positioning groove and a pressure sensor. The first positioning plate is installed on both sides of the extrusion block, a positioning rod is installed at the bottom end of the first positioning plate, and a pressure sensor is installed at the bottom end of the positioning rod. The second positioning plate is installed on both sides of the lower mold, and a positioning groove is arranged inside the second positioning plate. The first positioning plates on both sides of the extrusion block and the second positioning plates on both sides of the lower mold cooperate with each other, and the positioning rod at the bottom end of the first positioning plate can be inserted into the positioning groove in the middle of the second positioning plate. The positioning rod can be inserted into the positioning groove to position the extrusion block for lifting and lowering.

[0017] Furthermore, the inner diameter of the positioning groove is larger than the outer diameter of the positioning rod, and the positioning groove and the positioning rod constitute a sliding structure. The positioning rod can be inserted into the positioning groove, which indicates that the extrusion block model and the lower mold are matched.

[0018] The dry ice briquetting device that is convenient for replacing molds provided by the utility model has the advantages that: a positioning block is installed at the bottom end of the lower mold, a groove body that matches the positioning block is arranged on the workbench, the positioning block can be inserted into the groove body, the baffle plate and the buckle are connected by a first spring, the first spring is elastic, and the elasticity of the first spring can drive the buckle to be clamped into the positioning block, and the positioning block is fixed. By fixing the positioning block, the lower mold at the top thereof can be fixed. When the lower mold needs to be replaced, the buckle can be pulled open so that the buckle is no longer stuck in the positioning block, and the lower mold can be replaced, thereby achieving the purpose of facilitating the replacement of the lower mold of the dry ice extrusion block device.

[0019] By installing first positioning plates on both sides of the extrusion block, the first positioning plates on both sides of the extrusion block cooperate with the second positioning plates on both sides of the lower mold, and the positioning rod at the bottom end of the first positioning plate can be inserted into the positioning groove in the middle of the second positioning plate. The positioning rod can be inserted into the positioning groove to position the extrusion block for lifting and lowering. The fact that the positioning rod can be inserted into the positioning groove indicates that the extrusion block model and the lower mold cooperate. If the positioning rod cannot be inserted into the positioning groove, the pressure sensor at the bottom end of the positioning rod senses that the positioning rod touches the second positioning plate. The pressure sensor senses pressure and can control the device to stop working to prevent damage to the lower mold, thereby achieving the purpose of the dry ice extrusion block equipment to facilitate the guidance of the extrusion block.
