Detailed Implementation

[0021] The following is in conjunction with the appendix Figures 1 to 6 This utility model will be described in detail.

[0022] This utility model discloses a de-icing roller device for frozen products, comprising a fixed housing 1, wherein the fixed housing 1 is provided with an inlet 11 and an outlet 12 having a height difference, and a roller mechanism 2 is provided between the inlet 11 and the outlet 12. A drive mechanism 3 for driving the roller mechanism is also provided inside the fixed housing 1. The roller mechanism 2 is sequentially provided with a first roller 21, a positioning sleeve 22 movably connected to the first roller 21, and a second roller 23 movably connected to the positioning sleeve 22, wherein the first roller 21 and the second roller 23 are interconnected, and one end of the first roller 21 is connected to the inlet 11. One end of the first roller 21 and the second roller 23 are connected to the discharge port 12. The first roller 21 and the second roller 23 are provided with a large number of protrusions 24. The positioning sleeve 22 is provided with a chip discharge port 221 in the gap between the first roller 21 and the second roller 23. The driving mechanism 3 is provided with a motor 31, a first driving rod 32 connected to the first roller 21 and a second driving rod 33 connected to the second roller 23. One end of the second driving rod 33 is connected to the first driving rod 32. The motor 31 can drive the first driving rod 32 so that the first roller 21 and the second roller 23 roll in opposite directions. In this invention, frozen meat or other frozen products are fed into the inlet 11. When the frozen products come into contact with the rolling first roller 21, the protrusion 24 continuously taps the outside of the frozen products and makes them roll, thus removing ice chips from the surface of the frozen meat or other frozen products by rolling. Specifically, the outlet 12 and the inlet 11 are circular and have a height difference. When the fixed housing 1 is placed on the ground or other horizontal table, the angle between the straight line connecting the centers of the outlet 12 and the inlet 11 and the ground is between 10 and 15°. The protrusion 24 is semi-circular and has a certain degree of smoothness. Therefore, after the frozen products enter the first roller 21, under the influence of gravity, the rolling frozen products will gradually move towards the second roller 23 and even the outlet 12, which can more thoroughly clean the ice chips attached to the surface of the frozen products. More specifically, there is a chip discharge port 221 between the two rollers, which can discharge some ice chips. The ice chips cleaned from the first roller 21 can be discharged through the chip discharge port 221, reducing the amount of ice chips discharged from the discharge port 12, so that the ice chips remaining on the surface of the frozen product can be cleaned more efficiently in the second roller 23.

[0023] The fixed housing 1 is provided with a retainer 13 for fixing the positioning sleeve 22. This structure allows the roller mechanism 2 to be fixedly connected to the fixed housing 1. When the first roller 21 and the second roller 23 are rolling, the positioning sleeve 22 remains fixed. Firstly, it can ensure that the chip discharge port 221 will not be displaced to the side or top, causing the ice chips to be unable to be effectively discharged; secondly, it can position the first roller 21 and the second roller 23, preventing the first roller 21 and the second roller 23 from disengaging from the feed port 11 and the discharge port 12, resulting in high structural stability.

[0024] The feed inlet 11 is provided with a partition ring 14 that is movably connected to the first roller 21. The partition ring 14 extends from the feed inlet 11 into the interior of the first roller 21, covering the gap between the first roller 21 and the discharge outlet 12, and preventing ice chips from the frozen product from falling into the fixed housing 1.

[0025] The first roller 21 and the second roller 23 are provided with annular protrusions 25 on their exteriors, and the positioning sleeve 22 is provided with annular grooves 222 for engaging the annular protrusions 25. Through the engagement of the annular protrusions 25 and the annular grooves 222, the positions of the first roller 21 and the second roller 23 can be further positioned, preventing them from sliding. Additionally, a bearing can be provided between the annular protrusions 25 and the annular grooves 222 to reduce frictional wear of the equipment components and lower noise.

[0026] Considering the gap between the first roller 21 and the second roller 23, when the first roller 21 and the second roller 23 rotate in the same direction, the first roller 21 and the second roller 23 are relatively stationary, and the frozen product may get stuck in the gap between the first roller 21 and the second roller 23 and stop moving towards the discharge port 12. In this solution, gears 4 are provided on the outside of the first roller 21 and the second roller 23, at both ends of the first drive rod 32, and at both ends of the second drive rod 33. One end of the first drive rod 32 is connected to the gear of the first roller 21, and the other end of the first drive rod 32 is connected to the gear of the second drive rod 33. The other end of the second drive rod 33 is connected to the gear of the second roller 23. When the first drive rod 32 rotates, it directly drives the first roller 21 and indirectly drives the second roller 23 to rotate. The direction of rotation of the first roller 21 is opposite to that of the second roller 23. When the frozen product comes into contact with the first roller 21 and the second roller 23 at the same time, the frozen product will not only tumble but also rotate to prevent the frozen product from getting stuck in the gap between the first roller 21 and the second roller 23.

[0027] The positioning sleeve 22 is provided with a retaining ring 223 for fixing the positions of the first drive rod 32 and the second drive rod 33. The retaining ring 223 can fix the positions of the first drive rod 32 and the second drive rod 33, and fix the distance between the first drive rod 32 and the second drive rod 33 and the positioning sleeve 22, preventing the first drive rod 32 and the second drive rod 33 from disengaging from the connection with the first roller 21 and the second roller 23.

[0028] More specifically, the first drive rod 32 and the second drive rod 33 are provided with a limiting ring 34 that abuts against the retaining ring 223. After the retaining ring 223 abuts against the limiting ring 34, it can prevent the first drive rod 32 and the second drive rod 33 from sliding and avoid misalignment of the first drive rod 32 and the second drive rod 33.

[0029] The first drive rod 32 is provided with a first outer groove 35, and the rotor end of the motor 31 is provided with a second outer groove 36. A transmission belt 37 is provided between the first outer groove 35 and the second outer groove 36. This utility model can drive the first roller 21 and the second roller 23 to rotate simultaneously and in opposite directions with a single motor 31, without the need for a second drive device, resulting in low manufacturing cost and high structural stability.

[0030] The above description is only a preferred embodiment of this utility model. For those skilled in the art, based on the concept of this invention, there will be changes in the specific implementation methods and application scope. The content of this specification should not be construed as a limitation of this utility model. 。
