[0002] As a high-efficiency equipment in modern industry, the dry ice pellet making machine provides indispensable dry ice pellets for many industries with its unique working principle and excellent performance. The machine converts liquid carbon dioxide into solid dry ice pellets through precise compression, condensation and expansion processes to meet the needs of various application scenarios. During the manufacturing process, the dry ice pellet making machine first compresses the gaseous carbon dioxide to a high-pressure state through a compressor, and then uses a condenser to cool it to a low temperature to convert the gaseous carbon dioxide into a liquid state. Then, the liquid carbon dioxide expands rapidly through the expansion valve, and the temperature drops sharply, thereby converting it into solid dry ice pellets. Finally, through fine cutting equipment, these solid dry ice pellets are cut into the required size to adapt to different usage scenarios. The dry ice pellet making machine has the characteristics of high efficiency and low energy consumption. Its liquid to solid carbon dioxide conversion ratio is high, which can make full use of raw materials and reduce production costs. At the same time, the machine adopts advanced energy-saving technology to effectively reduce power consumption and save energy expenses for users.

DETAILED DESCRIPTION

[0021] 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.

[0022] Embodiment 1

[0023] See also Figures 1 to 4 A high-density dry ice particle making machine comprises a dry ice particle making machine body 1, the top of the right side of the dry ice particle making machine body 1 is connected to a discharge pipe 2, the bottom of the discharge pipe 2 is installed with a first mounting plate 3 by bolts, the first mounting plate 3 is hollow, the bottom of the first mounting plate 3 is fixedly connected with a bellows 4, the bottom of the bellows 4 is fixedly connected with a second mounting plate 5 by bolts, the second mounting plate 5 is hollow, so that the dry ice particles can be discharged from the discharge pipe 2 and then discharged downward through the first mounting plate 3, the bellows 4 and the second mounting plate 5, and two fixing seats 6 are fixedly connected on the right side of the dry ice particle making machine body 1 and at the bottom of the discharge pipe 2, and a transmission mechanism is rotatably connected between the two fixing seats 6, and the transmission mechanism can drive the second mounting plate 5 to move up and down.

[0024] The transmission mechanism includes a screw rod 701 , the outer side of the screw rod 701 is threadedly connected to a screw sleeve 702 , the top of the screw rod 701 is rotatably connected to a connecting sleeve 703 , and one side of the connecting sleeve 703 is rotatably connected to a fixing seat 6 .

[0025] The right sides of the screw sleeve 702 and the connecting sleeve 703 are fixedly connected with a connecting frame 704, one end of the connecting frame 704 is fixedly connected to the first mounting plate 3 and the second mounting plate 5 respectively, the bottom of the screw rod 701 is fixedly connected with a knob 705, and the top of the knob 705 is rotatably connected to the fixing seat 6.

[0026] The working principle of this embodiment is as follows: when it is necessary to lower the discharge height of the discharge pipe 2, the knob 705 can be turned, the knob 705 drives the screw 701 to rotate, the screw 701 drives the screw sleeve 702 to move downward, and when the screw sleeve 702 moves downward, it drives the second mounting plate 5 to move downward through the connecting frame 704. After the second mounting plate 5 moves downward, the bellows 4 will be stretched downward, so that the distance between the bellows 4 and the receiving container placed on the ground is reduced. After the bellows 4 is stretched, the effect of lowering the discharge height can be achieved, so that the bellows 4 is slightly higher than the top of the receiving container. At this time, the dry ice particles discharged from the dry ice particle making machine body 1 can directly enter the receiving container, and the discharged dry ice particles will not be spilled, so as to prevent the dry ice particles from spilling and causing pollution to the ground around the receiving container.

[0027] Embodiment 2

[0028] This embodiment is an improvement made on the basis of the first embodiment. For details, please refer to Figures 1 to 4 The top and bottom of the screw sleeve 702 are fixedly connected to the limiting block 8, and one side of the limiting block 8 is slidably connected to the dry ice particle making machine body 1.

[0029] By setting the limit block 8, when the screw sleeve 702 moves up and down, the limit block 8 will move up and down with the screw sleeve 702, and slide with the right side of the dry ice particle making machine body 1 during the movement, thereby stabilizing the screw sleeve 702 and making the screw sleeve 702 move up and down more smoothly.

[0030] The outer side of the screw rod 701 is rotatably connected to a first connecting ring 9 , and one side of the first connecting ring 9 is fixedly connected to the fixing seat 6 .

[0031] A spring 10 is fixedly connected to the other side of the first connecting ring 9 , and the spring 10 is sleeved on the outer side of the screw rod 701 .

[0032] One end of the spring 10 is fixedly connected to a second connecting ring 11 , and the second connecting ring 11 is clearance-fitted with the screw rod 701 .

[0033] By setting the first connecting ring 9, the spring 10 and the second connecting ring 11, the spring 10 applies elastic force to the second connecting ring 11, so that the second connecting ring 11 moves to the side away from the first connecting ring 9. When the screw sleeve 702 moves to contact with the second connecting ring 11 and continues to move, the elastic force of the spring 10 can buffer the screw sleeve 702 through the second connecting ring 11. At this time, the torque of turning the knob 705 increases. The user can determine that the screw sleeve 702 is about to move to the limit distance based on the increased torque, and then stop turning the knob 705, which can protect the screw sleeve 702 and the fixing seat 6 and prevent the two from colliding.

[0034] A positioning plate 12 is fixedly connected to one side of the first connecting ring 9 . The positioning plate 12 is located outside the spring 10 , and one side of the positioning plate 12 is opposite to the second connecting ring 11 .

[0035] By setting the positioning plate 12, the positioning plate 12 can limit the second connecting ring 11, so that the maximum distance that the second connecting ring moves toward the side close to the first connecting ring 9 is limited. For example, when the torque of the knob 705 increases and the knob 705 continues to be rotated, the positioning plate 12 will contact the second connecting ring 11, stop the movement of the screw sleeve 702, and prevent the continued rotation of the knob 705 from damaging the spring 10.

[0036] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
