Description

Technical Field

[0001] This invention relates to the field of dry ice spraying equipment technology, specifically a dry ice feeding switching device. Background Technology

[0002] Dry ice is widely used in industrial production, food preservation, and cleaning. Its production process typically involves grinding, sorting, and conveying dry ice particles. In existing technologies, dry ice feeding devices mostly adopt a single-channel structure, which cannot achieve multi-channel switching for feeding, resulting in limited production efficiency and problems such as clogging and uneven feeding during the grinding process.

[0003] When using dry ice, the issue of particle size arises. For example, in the cleaning field, dry ice needs to be used in different sizes, such as micro-particles and tiny particles, but existing equipment lacks the ability to process dry ice with precision.

[0004] Therefore, we propose a dry ice feeding switching device to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a dry ice feeding switching device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a dry ice feeding switching device, comprising: a driving device, a feeding hopper and a grinding structure, wherein the feeding hopper is fixedly installed on the grinding structure, the driving device drives and connects to the grinding structure, and the grinding structure includes a distributing bin and a grinding base, wherein the distributing bin is connected to the feeding hopper; A vertically arranged baffle is installed in the middle of the material distribution bin, which divides the material distribution bin into two channels. A grinding mechanism is installed in one of the channels, and both channels are connected to the ice distribution shaft in the grinding base. The material distribution bin is equipped with a rotating paddle structure, which rotates to switch the connection between the two channels of the material distribution bin and the feeding hopper.

[0007] Preferably, the paddle structure is rotatably positioned above the material distribution baffle.

[0008] Preferably, the paddle structure includes a paddle body, the lower end of which is rotatably connected to a rotating shaft, and the rotating shaft is fixedly installed on the inner wall of the material distribution bin.

[0009] Preferably, the lower end of the paddle body is integrally connected to the clamp, and the clamp is partially wrapped and rotatably sleeved on the rotating shaft.

[0010] Preferably, the clamp rotates and fits against the upper end of the material distribution baffle.

[0011] Preferably, one channel of the material distribution bin is directly connected to the ice dispensing shaft, and the other channel is connected to the ice dispensing shaft after passing through the grinding mechanism.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. Dual-channel switching is achieved by rotating the lever, eliminating the need for complex transmission mechanisms, resulting in fast response and easy operation; 2. The dual-channel design supports both dry ice granulation and fine particle spraying, meeting different particle size requirements and improving product adaptability. 3. Modular structure design facilitates disassembly, cleaning, and replacement of worn parts, reducing maintenance costs. Attached Figure Description

[0015] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0016] Please see Figure 1-4 The present invention provides a technical solution: a dry ice feeding switching paddle device, comprising: a driving device 1, a feeding hopper 2, a grinding structure 3, and a paddle structure 4 disposed in the grinding structure 3.

[0017] The feeding hopper 2 is fixedly installed above the grinding structure 3 and is used to receive dry ice particles to be ground.

[0018] The drive unit 1 is connected to the grinding structure 3 through a transmission mechanism to provide power to it.

[0019] The grinding structure 3 includes a material distribution bin 32, a grinding base 33, and a fixed shell 31. The material distribution bin 32 is located below and connected to the feeding hopper 2.

[0020] The grinding base 33 and the material distribution bin 32 are fixedly installed inside the fixed shell 31, and the material distribution bin 32 is located above the grinding base 33.

[0021] The material distribution bin 32 is vertically equipped with a material distribution baffle 321, which divides the material distribution bin 32 into two independent channels. One channel is equipped with a grinding mechanism 34 for fine crushing of dry ice; the other channel leads directly to the ice dispensing shaft 35. Both channels eventually converge into the ice dispensing shaft 35 in the grinding base 33 for output.

[0022] The paddle structure 4 is rotatably mounted inside the material distribution bin 32, above the material distribution baffle 321. This structure includes a paddle body, the lower end of which is rotatably connected to a rotating shaft 42 via a clamp 41. The rotating shaft 42 is fixedly mounted on the inner wall of the material distribution bin 32.

[0023] The chuck 41 is semi-enclosed and fitted onto the rotating shaft 42, allowing it to rotate freely around the shaft. During the rotation of the paddle body, the chuck 41 at its lower end remains in contact with the upper surface of the material distribution baffle 321, ensuring that no material leakage occurs during the switching process.

[0024] Working principle: When it is necessary to switch the feeding channel, the paddle structure 4 is driven to rotate around the rotating shaft 42 by an external control mechanism (such as a cylinder, motor, or manual operation). The paddle body guides the dry ice particles from the feeding hopper 2 into one of the channels. If the lever is turned to the left channel, the dry ice will directly enter the ice dispensing shaft 35 and then be ejected; If the lever is turned to the right channel, the dry ice is first finely crushed by the grinding mechanism 34, and then dispensed and sprayed out by the ice dispensing shaft 35.

[0025] The flexible rotation of the lever allows for rapid switching between the two channels, meeting production needs for different particle sizes and improving the continuity and stability of material feeding.

[0026] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0027] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
