A dry ice forming device

Abstract

This utility model provides a dry ice forming device, relating to the field of dry ice processing. The dry ice forming device includes multiple annularly distributed supporting cavities. A compaction mechanism is disposed above each supporting cavity. The compaction mechanism and the supporting cavity rotate together. Inside each supporting cavity is an ejection mechanism for discharging the compacted dry ice outwards. The ejection mechanism rotates a certain angle after the compaction mechanism has descended and then rises along with it. This dry ice forming device, by having the compaction mechanism and ejection mechanism rotate together with the supporting cavities, allows the device to perform compaction and ejection without pausing during the process, achieving compaction and ejection simultaneously with rotation. This reduces the time spent pausing during compaction and ejection, thereby improving the efficiency of the device.

Description

Technical Field

[0001] This utility model relates to the field of dry ice processing technology, specifically a dry ice forming device. Background Technology

[0002] Many industries, such as cleaning, biological product transportation, food preservation, catering, mechanical cold assembly, and scientific experiments, require a large amount of block dry ice. When dry ice is first produced, it is usually in granular form. In order to meet the needs of transportation or use, the granular dry ice is pressed into blocks using a dry ice briquetting machine.

[0003] CN210970058U describes a dry ice briquetting machine, including a control box, a frame, and a work platform mounted on the frame. The control box is located on one side of the frame's width. A hopper is mounted on the work platform, and a compression mechanism is located on one side of the hopper. The compression mechanism includes a first hydraulic cylinder mounted on the frame, positioned below the frame. A push plate is mounted on one end of the extension rod of the first hydraulic cylinder, which passes through the top surface of the frame. A push block is mounted on the side of the push plate near the work platform. A compression cavity is formed on the work platform, extending vertically through it. The push block is located at the bottom of the compression cavity and is slidably connected to the inner wall of the compression cavity. A PLC controller for controlling the movement of the first hydraulic cylinder is located inside the control box. This technical solution allows for adjustable mold cavity size, enabling the pressing of dry ice blocks of different thicknesses as needed. However, the machine experiences waiting time during the feeding and discharging processes, resulting in low operating efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a dry ice forming device that solves the problem mentioned in the background technology that the device needs to be paused during loading and unloading, resulting in wasted time.

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] See Figure 1-4 A dry ice forming device includes multiple annularly distributed support cavities 1, as well as other auxiliary devices such as insulation devices. A compaction mechanism 2 is provided above each support cavity 1. The compaction mechanism 2 and the support cavity 1 rotate together. An ejection mechanism 3 is provided inside the support cavity 1 to discharge the compacted dry ice outward. After the compaction mechanism 2 has descended, the ejection mechanism 3 rotates a certain angle and rises together with the compaction mechanism 2. By rotating the compaction mechanism 2 and the ejection mechanism 3 together with the support cavity 1, the device can be compacted and ejected without pausing during the compaction and ejection process. Compaction and ejection can be achieved while rotating, thereby reducing the time required for pausing during compaction and ejection and improving the efficiency of the device.

[0024] A feeding conveying mechanism 4 is provided on one side of the bearing cavity 1, and a discharging conveying mechanism 5 is provided on the other side of the bearing cavity 1. The ejection mechanism 3 completes the descent and retraction between the feeding conveying mechanism 4 and the discharging conveying mechanism 5.

[0025] A support 6 is provided inside the bearing cavity 1, and a compaction mechanism 2 is suspended on the top of the support 6. The compaction mechanism 2 includes a telescopic sleeve 201, and a pressure head 202 is provided at the free end of the telescopic sleeve 201. By setting the support 6, the compaction mechanism 2 and the bearing cavity 1 can be connected together and thus rotate as a whole. The device also includes a bracket for supporting the bearing cavity 1 and a rotating disk connected to the support 6. The rotating disk is equipped with a toothed disc at the bracket, and the toothed disc and the support 6 are driven to rotate by an external power mechanism.

[0026] The ejection mechanism 3 includes a telescopic column 301 disposed on the bottom wall of the bearing cavity 1. A lower support plate 302 is fixedly installed at the free end of the telescopic column 301. By extending the telescopic column 301, the upper surface of the lower support plate 302 can be flush with the upper surface of the bearing cavity 1, thereby enabling the formed dry ice to be ejected.

[0027] A support column 303 is fixedly installed on the inner bottom wall of the bearing cavity 1. When the telescopic column 301 retracts, the lower support plate 302 contacts the support column 303. When the telescopic column 301 retracts, the support column 303 supports the lower support plate 302, thereby reducing the pressure on the telescopic column 301 and ensuring that the telescopic column 301 will not deform during the compaction process.

[0028] The bearing cavity 1 is equipped with a rotary encoder 7, which controls the operation of the ejection mechanism 3 and the compaction mechanism 2. By setting the rotary encoder 7, the angle of the bracket 6 relative to the feeding conveying mechanism 4 is used to determine when the ejection mechanism 3 and the compaction mechanism 2 should work.

[0029] An annular conductive plate 8 is provided on one side of the bearing cavity 1, and the ejection mechanism 3 is provided with a conductive contact part 9 extending to the outside of the bearing cavity 1. The annular conductive plate 8 is provided on the side of the feed conveying mechanism 4 and the discharge conveying mechanism 5. The annular conductive plate 8 is provided at the corresponding process position. When the conductive contact part 9 is connected by the annular conductive plate 8, the ejection mechanism 3 extends completely within a specified time. When the conductive contact part 9 is no longer conductive, the ejection mechanism 3 retracts within a specified time. Similarly, the compaction mechanism 2 can also be controlled by the same principle, so as to achieve the completion of the specified action at the specified work position. The annular conductive plate 8 can be provided not only on the side wall of the device but also at the bottom of the device.

[0030] The bearing cavity 1 is inverted boss shape, and the pressure head 202 is boss shape and is adapted to the upper opening of the bearing cavity 1. This setting facilitates demolding.

[0031] In use, by rotating the compaction mechanism 2 and the ejection mechanism 3 together with the bearing cavity 1, the device can be compacted and ejected without pausing during the compaction and ejection process. This reduces the time required for pausing during compaction and ejection, thereby improving the efficiency of the device.

[0032] It should be noted that in this paper, relational terms such as first and second are used only 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.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
