Description

Technical Field

[0001] The utility model relates to the technical field of quick-frozen food processing equipment, and more specifically, to an anti-adhesion device. Background Art

[0002] Quick-frozen food refers to food that needs to be quick-frozen. After appropriate pre-treatment, it is rapidly frozen by various methods, and after packaging, it is stored at -18°C to -20°C (general requirement, different foods have different temperature requirements) and delivered to the consumption location under a continuous low-temperature condition as a low-temperature product. Since the 1990s, the annual output of quick-frozen products has been increasing at a rate of more than 20% per year, becoming a new star in the food industry.

[0003] Currently, quick-frozen foods such as tangyuan and shao-mai among Chinese dim sum, fish balls and fish dumplings in hot pot seasonings, and quick-frozen fruits and vegetables such as green peas and corn kernels are very popular in the market. These similar foods inevitably need to use a quick-freezing line device during the process from forming to packaging. Since a part of moisture will remain on the surface of the food during the pre-treatment process, after being quick-frozen by the quick-freezing line, the foods on the quick-freezing line are likely to stick together, which is not conducive to the subsequent packaging equipment to package the quick-frozen food, and reduces the packaging efficiency of the packaging equipment.

[0004] In view of the above situation, the existing conventional method is to arrange inspectors at the discharge port of the quick-freezing line to knock the stuck-together foods with a relatively appropriate weight heavy object to disperse the foods by gravity. However, since this method is based on manual labor, the generated force is uncontrollable. During the implementation process, it is very likely that the quick-frozen food will be damaged due to excessive force, resulting in increased costs, or the stuck-together foods will be missed, causing inconvenience to subsequent packaging; in addition, the need to specially arrange personnel for this step also increases the labor cost.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] To further explain the technical solution of the present utility model, the present utility model will be elaborated in detail through specific embodiments below.

[0028] Referring to Figure 1 and Figure 2 as shown, the present utility model discloses an anti - adhesion device which is arranged on a conveyor belt 3 of a quick - freezing line for quick - frozen food. The device includes a knocking mechanism 10 located at the discharge port of the quick - freezing line. The knocking mechanism 10 includes: first brackets 1 arranged on both sides of the conveyor belt 3, a first rotating shaft 11, a first motor 12, and at least one knocking member 13. Among them, the first rotating shaft 11 is parallel to the conveyor belt 3 and is rotatably arranged on the first brackets 1. The width of the first rotating shaft 11 is not less than the width of the conveyor belt 3. The first motor 12 can be arranged on the first brackets 1 and is drivingly connected to the first rotating shaft 11 to drive the first rotating shaft 11 to rotate. The knocking member 13 hangs down from the first rotating shaft 11 and hangs above the conveyor belt 3. The knocking member 13 can swing relative to the first rotating shaft 11. The first motor 12 can drive the first rotating shaft 11 to rotate reciprocally, thereby driving the knocking member 13 to swing reciprocally above the conveyor belt 3 to simultaneously knock the quick - frozen food arranged side - by - side on the conveyor belt 3.

[0029] In this embodiment, there are multiple knocking members 13, and the multiple knocking members 13 are horizontally and evenly dispersed and suspended above the conveyor belt 3. The knocking member 13 can include a cylindrical pendulum 132. The pendulum 132 is connected to the first rotating shaft 11 through a chain 131. The upper end of the chain 131 is connected to the circumferential surface of the first rotating shaft 11, and the lower end of the chain 131 is connected to the middle position of the circumferential surface of the pendulum 132. Each pendulum 132 is parallel to the conveyor belt 3. The horizontal and even dispersion of each knocking member 13 can enable the knocking range of the knocking member 13 to evenly cover the width of the conveyor belt 3, so that the quick - frozen food moving forward side - by - side on the conveyor belt 3 can all be knocked. When the first motor 12 drives the first rotating shaft 11 to move reciprocally, the knocking member 13 also moves reciprocally accordingly. And because the chain 131 is used as the connection, the pendulum 132 at the lower end of the chain 131 will knock the quick - frozen food under the action of gravity. The knocking force is determined by the weight of the pendulum 132, and the knocking mechanism 10 can be made suitable for different quick - frozen foods by replacing pendulums 132 with different weights or shapes.

[0030] The first bracket 1 in this embodiment is a triangular bracket, and the first rotating shaft 11 is pivotally arranged between the left and right sides of the first bracket 1. Preferably, the vertical distance between the first rotating shaft 11 and the conveyor belt 3 is adjustable, that is, the height of the first rotating shaft 11 relative to the conveyor belt 3 can be adjusted by adjusting the height of the first bracket 1 or the position of the first rotating shaft 11 on the first bracket 1, so that the knocking mechanism 10 of the present utility model is applicable to different sizes and types of quick - frozen foods.

[0031] In order to further improve the safety and convenience of the use of the knocking mechanism 10, a first cover 14 is also provided on the first bracket 1. The top of the first cover 14 is located above the first rotating shaft 11, and the lower part of the first cover 14 is open and suspended above the conveyor belt 3. The first cover 14 covers the first rotating shaft 11 and the knocking member 13. Thus, the first cover 14 covers all the structures of the knocking mechanism 10 except the first motor 12 below, which can ensure the safety of the knocking mechanism 10 and at the same time prevent the quick-frozen food knocked by the knocking member 13 from flying out of the conveyor belt 3.

[0032] A first self-cleaning pipeline 15 is also provided on the inner top of the first cover 14. The first self-cleaning pipeline 15 is located above the first rotating shaft 11, and a number of first water spray nozzles 151 are distributed circumferentially on the first self-cleaning pipeline 15. One end of the first self-cleaning pipeline 15 is connected to an external cleaning liquid. In this embodiment, the first cleaning pipeline is connected to a cleaning liquid tank 4. The first self-cleaning pipeline 15 is also started by the first motor 12 and can be started at any time to spray cleaning liquid on the first rotating shaft 11 and the knocking member 13 under the first cover 14 to keep the parts that may come into contact with the quick-frozen food clean. The cleaning liquid can be a disinfectant, clean water, etc.

[0033] Refer to Figure 3 、 Figure 4 、 Figure 5 In addition, a flattening mechanism 20 is further included in the anti-sticking device of the present utility model at the feeding port of the quick-freezing line. The flattening mechanism 20 can be located behind the transmission of the knocking mechanism 10. The flattening mechanism 20 may include: second brackets 2, second rotating shafts 21, second motors 22, and a number of blades 23 provided on both sides of the conveyor belt 3. Among them, the second rotating shafts 21 are parallel to the conveyor belt 3 and are rotatably provided on the second brackets 2. The width of the second rotating shafts 21 is not less than the width of the conveyor belt 3. The second motors 22 can be provided on the second brackets 2 and are drivingly connected to the second rotating shafts 21. The blades 23 are evenly distributed on the circumferential surface of the second rotating shafts 21. A plurality of blades 23 can be radially distributed on the second rotating shafts 21. The bottoms of the blades 23 are parallel to the conveyor belt 3 and are suspended above the conveyor belt 3. The second motors 22 drive the second rotating shafts 21 to rotate unidirectionally.

[0034] When the flattening mechanism 20 is started, it can be selected to make the second motor 22 drive the second rotating shaft 21 to rotate in the direction opposite to the advancing direction of the conveyor belt 3. The distance between the blades 23 and the conveyor belt 3 can be set to the height of a single layer of food, so that the blades 23 can rotate and dial the food that overlaps after ripening, and after the food is flattened on the conveyor belt 3, it enters the subsequent quick-freezing step, further avoiding the adhesion of the products after quick-freezing. Among them, the size, width, and shape of the blades 23 can be set according to the size of different foods.

[0035] The second bracket 2 in this embodiment is a triangular bracket, and the second rotating shaft 21 is pivotally mounted between the left and right sides of the second bracket 2. Preferably, the vertical distance between the second rotating shaft 21 and the conveyor belt 3 is adjustable, that is, the height of the second rotating shaft 21 relative to the conveyor belt 3 can be adjusted by adjusting the height of the second bracket 2 or the position of the second rotating shaft 21 on the second bracket 2, so that the paving mechanism 20 of the utility model is suitable for quick-frozen foods of different sizes and types.

[0036] In order to further improve the safety of the knocking mechanism 10, a second cover body 24 is also provided on the second bracket 2. The top of the second cover body 24 is located above the second rotating shaft 21, and the bottom of the second cover body 24 is open and suspended above the conveyor belt 3. The second cover body 24 covers the second rotating shaft 21 and the blades 23.

[0037] A second self-cleaning pipe 25 is provided at the top of the inner side of the second cover body 24. The second self-cleaning pipe 25 is located above the second rotating shaft 21 and has a plurality of second water spray ports 251 distributed in the circumferential direction. One end of the second self-cleaning pipe 25 is connected to an external cleaning liquid. In this embodiment, the second cleaning pipe is connected to a cleaning liquid pool 4. The second self-cleaning pipe 25 is also started by the second motor 22 and can be started at any time to spray cleaning liquid on the second rotating shaft 21 and the blades 23 under the second cover body 24 to keep the parts that may contact the quick-frozen food clean. The cleaning liquid can be a disinfectant, clean water, etc.

[0038] In addition to being able to disperse the quick-frozen food without destroying it to prevent it from sticking together, the utility model is also flexible. Specifically, the knocking mechanism 10 and the flattening mechanism 20 are both controlled by independent motors and can be selectively started according to actual conditions. They can also be adjusted according to different foods. For example, the knocking mechanism 10 can adjust the swing arc and speed of the knocking member 13 by adjusting the rotation angle and speed of the first motor 12; the flattening mechanism 20 can adjust the moving effect of the blade 23 by adjusting the rotation direction and speed of the second motor 22.

[0039] The above is only an embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
