Description

Technical Field

[0001] This disclosure relates to the field of quick-freezing equipment technology, and more specifically, to a device for reducing ice formation on the conveyor belt of a quick-freezing machine. Background Technology

[0002] Currently, most quick-freezing machines use conventional cylindrical rollers installed under the conveyor belt, which can cause jamming when the conveyor belt freezes. To solve this problem, a device to reduce icing on the conveyor belt is added to the quick-freezing machine based on customer requirements. Utility Model Content

[0003] In order to overcome the problem that most of the support rollers installed under the conveyor belt of existing quick-freezing machines are conventional support rollers (cylindrical), which cause the conveyor belt to jam after freezing, this utility model provides a device to reduce freezing of conveyor belts in quick-freezing machines.

[0004] To achieve the above objectives, this disclosure provides a device for reducing icing on the conveyor belt of a quick-freezing machine, comprising multiple ice-scraping mechanisms. The ice-scraping mechanisms are used to install at the inlet of the quick-freezing machine and / or at the middle section where there is a temperature difference. Each ice-scraping mechanism includes a rotating shaft and multiple rollers. The multiple rotating shafts are spaced apart along the extension direction of the conveyor belt. The two ends of the rotating shafts are used to fix them to the frame of the quick-freezing machine and are positioned below the conveyor belt. The rollers are sleeved on the outer periphery of the rotating shafts and are rotatably connected to the outer periphery of the rollers. The circumferential structure of the rollers is polygonal, and the polygonal shape is used to contact the bottom of the conveyor belt.

[0005] Optionally, the ice-scraping mechanism also includes multiple limiting components, the number of which is twice the number of support rollers. The multiple limiting components are respectively located on both sides of the multiple support rollers and fixed on the rotating shaft.

[0006] Optionally, the limiting element is a screw or a locating pin.

[0007] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:

[0008] The frozen goods entering the freezer have a high moisture content and will quickly freeze on the conveyor belt upon contact with the cold air inside. The ice blocks can push the conveyor belt up, reducing the passage space and causing jamming. To prevent jamming, a device to reduce icing on the conveyor belt is added at the freezer inlet and / or in the middle where there is a temperature difference. This device uses polygonal rollers mounted around the outer circumference of a rotating shaft, which is fixed to the freezer frame. The rollers can rotate relative to the shaft. As the conveyor belt runs, it drives the rollers to rotate. The pointed outer edges of the rollers (the polygonal outer angles) come into contact with and rub against the conveyor belt, reducing icing or removing already frozen ice.

[0014] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0015] Please see Figures 1 to 3 This disclosure provides a device for reducing ice formation on the conveyor belt of a quick-freezing machine, including an ice-scraping mechanism. The ice-scraping mechanism is installed at the inlet of the quick-freezing machine. The ice-scraping mechanism includes a rotating shaft 2 and a plurality of rollers 1. The two ends of the rotating shaft 2 are fixed to the frame 4 of the quick-freezing machine and are positioned below the conveyor belt 3. The rollers 1 are sleeved on the outer periphery of the rotating shaft 2 and are rotatably connected to the outer periphery of the rollers 1. The circumferential structure of the rollers 1 is polygonal, and the polygonal shape is used to contact the bottom of the conveyor belt 3.

[0016] It is understandable that the frozen goods entering the freezer have a high water content, and upon contact with the cold air inside the freezer, they will quickly freeze on the conveyor belt 3. The ice blocks push the conveyor belt 3 up, reducing the passage space and easily causing jamming. To avoid jamming, a device to reduce icing on the conveyor belt 3 is added at the freezer inlet or in the middle where there is a temperature difference. This device uses a polygonal support roller 1 mounted on the outer circumference of a rotating shaft 2, which is fixed to the freezer frame 4. The support roller 1 can rotate relative to the rotating shaft 2. When the conveyor belt 3 runs, it drives the support roller 1 to rotate. As the support roller 1 rotates, its outer pointed ends (polygonal outer angles) contact and rub against the conveyor belt 3, thereby reducing icing or removing frozen ice blocks. When the conveyor belt 3 stops rotating, the support roller 1 also stops rotating. The advantages of this device to reduce icing on the freezer conveyor belt are: simple design and easy maintenance; it solves the problem of icing on the freezer conveyor belt 3; it is safe and reliable, and the equipment does not require disassembly.

[0017] In Example 1, the ice-scraping mechanism is only installed at the inlet of the blast freezer. In this case, the conveyor belt 3 of the blast freezer runs from the inlet to the outlet. The frozen materials (such as peach petals and corn) that just enter the blast freezer have a high water content and will quickly freeze on the conveyor belt 3 upon contact with the cold air inside the blast freezer. The ice blocks push up the conveyor belt 3, reducing the passage space and easily causing jamming. To avoid jamming, an ice-scraping mechanism is installed at the inlet of the blast freezer. Specifically, this device uses a polygonal support roller 1 fitted around the outer periphery of a rotating shaft 2. The rotating shaft 2 is fixed to the frame 4 of the blast freezer, and the support roller 1 can rotate relative to the rotating shaft 2. When the conveyor belt 3 runs, it drives the support roller 1 to rotate. As the support roller 1 rotates, its outer pointed ends (polyhedral outer angles) come into contact with and rub against the conveyor belt 3, thereby reducing icing or removing frozen ice blocks.

[0018] In Example 2, the ice scraping mechanism is installed only in the middle of the quick-freezing machine where there is a temperature difference. The quick-freezing machine includes two mesh belts 3 with a height difference. That is, after the frozen material enters the quick-freezing machine, it first enters the mesh belt 3 at the higher position, and then gradually moves from the mesh belt 3 at the higher position to the mesh belt 3 at the lower position. There is a certain temperature difference in the space where the two mesh belts 3 are located. Therefore, technicians can install ice scraping mechanisms under the two mesh belts 3 respectively to remove the ice on the two mesh belts 3.

[0019] In Example 3, the ice scraping mechanism is installed at the inlet of the quick-freezing machine and at the middle where there is a temperature difference. In this case, the quick-freezing machine includes two mesh belts 3 with a height difference. Multiple ice scraping mechanisms can be installed below both ends of the high mesh belt 3 and below the low end near the high end to ensure the de-icing effect of the two mesh belts 3.

[0020] In one implementation, please refer to Figure 1 and Figure 3 The ice-scraping mechanism also includes multiple limiting components 5. The number of limiting components 5 is twice the number of support rollers 1. The multiple limiting components 5 are respectively located on both sides of the multiple support rollers 1 and fixed on the rotating shaft 2 to prevent the support rollers 1 from moving too much relative to the rotating shaft 2 during rotation, thus ensuring the ice-scraping effect.

[0021] In one implementation, please refer to Figure 1 and Figure 3 The limiting component 5 is a screw or a positioning pin, which is relatively easy to obtain and facilitates the assembly of the ice scraping mechanism.

Those skilled in the art will understand that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the invention. Furthermore, under the teachings of this invention, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the invention.
