However, the shapes and specifications of different production equipment are different. When making molecular sieves, extrusion dies of different shapes should be replaced. However, the extrusion dies in existing devices are generally fixed and not easy to replace according to needs, which has certain limitations. In view of this, we propose a molding extrusion device for carbon molecular sieve processing. Utility Model Content

DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] Embodiment 1
[0021] Reference Figure 1-Figure 4 A forming extrusion device for processing carbon molecular sieves comprises a support platform 1, and an extrusion sleeve 2 arranged on the support platform 1, and an extrusion screw 4 for raw material transportation is rotatably installed in the extrusion sleeve 2, a feed hopper 3 for raw material delivery is provided on the extrusion sleeve 2, a driving component 5 for driving the extrusion screw 4 to rotate is provided on the support platform 1, an extrusion die 7 is provided at one end of the extrusion sleeve 2, and an assembling mechanism 8 for splicing is provided on the extrusion die 7. When the carbon molecular sieve is produced, the raw material can be first introduced into the extrusion sleeve 2 through the feed hopper 3, and then the driving component 5 is started to control the movement of the extrusion screw 4. When the clamping screw 4 moves, it will drive the raw material into the extrusion die 7 for shaping. After the shaping is completed, the production of the carbon molecular sieve is completed. When it is necessary to replace the extrusion die 7 of different specifications, it can be achieved through the assembling mechanism 8.
[0022] The assembling mechanism 8 includes a knob 81 arranged at one end of the extrusion die 7, a threaded sleeve 83 fixedly connected to the knob 81 is threadedly installed at one end of the extrusion die 7, a sliding groove is provided on the threaded sleeve 83, an assembling gear 84 is rotatably installed on the extrusion die 7, an annular rack 85 rotatably connected to the extrusion die 7 is meshed on the outside of the assembling gear 84, a first transmission rod 86 slidably connected to the sliding groove is fixedly installed on the upper part of the annular rack 85, a fixed arc rod 87 coaxially fixed to the assembling gear 84 is rotatably installed at the other end of the extrusion die 7, a fixing groove 88 mutually engaged with the fixed arc rod 87 is provided in the extrusion sleeve 2, and under normal conditions, the fixed arc rod 87 is retracted in the threaded sleeve 83. When installing the extrusion die 7, the extrusion die 7 can be first inserted into the extrusion sleeve 2, and then the threaded sleeve 83 can be driven to rotate by the knob 81. The threaded sleeve 83 drives the annular rack 85 to rotate through the cooperation of the sliding groove and the first transmission rod 86. When the annular rack 85 rotates, it will drive the assembly gear 84 to rotate through the meshing of the teeth. When the assembly gear 84 rotates, it will synchronously drive the fixed arc rod 87 to rotate until it is transferred into the fixed groove 88. The installation of the extrusion die 7 is completed by the mutual engagement of the fixed arc rod 87 and the fixed groove 88. When disassembling, it only needs to rotate the threaded sleeve 83 in the opposite direction. The entire loading and unloading process is simple and convenient, which greatly reduces the difficulty of replacing the extrusion die 7.
[0023] An extrusion assembly 89 for extruding the extrusion die 7 is provided at the left end of the extrusion sleeve 2. The extrusion assembly 89 includes an extrusion rod 891 rotatably mounted at one end of the extrusion sleeve 2, and one end of the extrusion rod 891 is tightly fitted with the extrusion die 7. An extrusion torsion spring 892 fixedly connected to the extrusion sleeve 2 is provided at the rotating end of the extrusion rod 891. A resistance rod 897 is elastically mounted in the extrusion sleeve 2. A plurality of driving protrusions 895 are fixedly mounted on the upper portion of the resistance rod 897, and a transmission protrusion 82 that is in conflict with the threaded sleeve 83 is fixedly mounted on the lower portion. A limiting plate 894 is slidably mounted in the extrusion sleeve 2, and a driving protrusion 896 that is in conflict with the driving protrusion 895 is fixedly mounted on the lower portion of the limiting plate 894. A limiting groove 893 that is mutually engaged with the limiting plate 894 is provided at the rotating end of the extrusion rod 891. During the insertion process of the extrusion die 7, one end of the threaded sleeve 83 drives the limiting plate 894 to move by contacting the transmission protrusion 82. When the plate 894 moves backward and is screwed into the threaded sleeve 83 to drive the fixed arc rod 87 to rotate, the threaded sleeve 83 will contact the transmission protrusion 82 to drive the limit plate 894 to continue to move an end distance, and then the driving protrusion 1 895 set on the upper part of the limit plate 894 will drive the limit plate 894 to disengage from the limit groove 893 by contacting the driving protrusion 2 896. At this time, under the action of the extrusion torsion spring 892, the extrusion rod 891 automatically rotates, and uses the tail end protrusion to extrude the extrusion die 7 to fit the extrusion sleeve 2 more closely, thereby reducing the outflow of part of the raw material from the assembly gap between the extrusion sleeve 2 and the extrusion die 7, thereby avoiding the waste of raw materials. During disassembly, the lack of extrusion of the contact rod 897 will contact the extrusion rod 891 to quickly reset, and through the mutual contact between the driving protrusion 1 895 and the driving protrusion 2 896, the limit plate 894 is inserted into the limit groove 893, thereby achieving the fixation of the extrusion rod 891.
[0024] Embodiment 2
[0025] Reference Figure 1-Figure 4 , this embodiment is basically the same as the first embodiment, and is more optimized in that the driving assembly 5 includes a driving motor 51 fixedly mounted on the support platform 1, and a driving wheel 2 54 coaxially fixed with the extrusion screw 4 is fixedly mounted on the output end of the driving motor 51, and a driving belt 53 is provided on the external transmission sleeve of the driving wheel 2 54. A driving wheel 1 52 and a driving wheel 3 55 are installed on the outside of the driving wheel 2 54 through the driving belt 53. An oscillation rod 521 that continuously collides with the feed hopper 3 is elastically mounted on one side of the driving wheel 1 52. When the carbon molecular sieve is made, the driving motor 51 can be started to drive the driving wheel 2 54 to rotate. When the driving wheel 2 54 rotates, the extrusion screw 4 is driven to rotate, and the driving wheel 1 52 and the driving wheel 3 55 are driven to rotate synchronously through the transmission connection of the driving belt 53. When the driving wheel 1 52 rotates, it will continuously drive the oscillation rod 521 arranged thereon to collide with the feed hopper 3, thereby accelerating the unloading speed of the raw materials therein and avoiding the bridging phenomenon therein.
[0026] A second transmission rod 56 is coaxially fixed to one side of the driving wheel three 55, and a transmission turntable 57 is coaxially fixed to one end of the second transmission rod 56. A cutting knife 58 for cutting strip molecular sieves is fixedly installed on the transmission turntable 57. When the driving wheel three 55 rotates, the transmission turntable 57 is synchronously driven to rotate through the second transmission rod 56. Since the transmission turntable 57 is provided with a cutting knife 58, the carbon molecular sieve will be continuously cut by the cutting knife 58 when the transmission turntable 57 rotates.
[0027] A boosting chamber 6 is provided inside the extrusion sleeve 2 and close to the extrusion die 7, and the internal size of the boosting chamber 6 increases from left to right. Since the internal size of the boosting chamber 6 increases from left to right, the raw material entering the boosting chamber 6 will be squeezed, and under the action of pressure, the molding of the carbon molecular sieve can be further improved.
[0028] 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.
