Description

Technical Field

[0001] The present application relates to the field of conveyor belts, and in particular to a rice noodle conveyor belt. Background Art

[0002] The rice noodle production process involves kneading, extruding, cutting, drying, and packaging. After the rice noodles are extruded, they are usually transported to the cutting station via a conveyor belt for cutting. During the transportation process, the rice noodles are in a wet state and have strong adhesion. The rice noodles are prone to sticking to each other, so the rice noodles need to be initially air-dried.

[0003] The conveyor belt in the prior art usually does not have the air-drying function, and needs to be additionally equipped with a fan for air-drying. The blowing angle, blowing range, and blowing strength of the fan are difficult to accurately control. Excessive wind force can easily cause bending and deformation in the wind-receiving center area, and the wind energy outside the wind-receiving boundary cannot be effectively utilized, resulting in waste. If the wind force is too small, there will be insufficient wind at the wind-receiving boundary, and the initial air-drying effect cannot be achieved. In addition, due to the instability of wind direction, range, and strength, it is easy for the rice noodles in different positions to have different initial air-drying degrees. In the later drying process, the area with a larger initial air-drying degree is prone to over-drying, which not only affects the quality of the rice noodles, but also causes invalid energy consumption losses due to over-drying. This open air-drying process will produce more water vapor, affecting the working environment. Summary of the invention

[0004] In view of this, a rice noodle conveyor belt is proposed, which provides uniform and stable airflow to all parts of the rice noodles during the initial air-drying process of the rice noodles, the wind intensity of the rice noodles is easy to adjust, the air-drying degree of the rice noodles is uniform in all parts, the ineffective energy loss is low, and the impact on the working environment is small.

[0010] In some embodiments of the above-mentioned rice noodle conveyor belt, a plurality of forward-inclined guide bars and backward-inclined guide bars are horizontally fixedly connected to the lower surface of the upper partition plate, and the forward-inclined guide bars and the backward-inclined guide bars are arranged at intervals in the conveying direction, and the forward-inclined guide bars and the backward-inclined guide bars are inclined relative to the conveying direction and in opposite directions, one end of the forward-inclined guide bar is in contact with the first side panel, and the other end of the forward-inclined guide bar is spaced apart from the second side panel, one end of the backward-inclined guide bar is spaced apart from the first side panel, and the other end of the backward-inclined guide bar is in contact with the second side panel, and the forward-inclined guide bar and the backward-inclined guide bar separate the upper part of the upper channel into an S shape.

[0011] In some embodiments of the above-mentioned rice noodle conveyor belt, the front end of the lower partition is aligned with the front end of the upper partition, and the rear end of the lower partition is located in front of the rear end of the upper partition.

[0012] In some embodiments of the above-mentioned rice noodle conveyor belt, a notch extending vertically through the lower partition is provided on the lower partition, and the notch is located on the front side of the center of the upper partition.

[0018] Beneficial effects of the present invention:

[0019] The air pump draws air from the center of the upper channel, causing the air pressure in the center area of ​​the upper channel to drop, and the external air is sucked in from both ends of the upper and lower airways. The airflow blows the rice noodles during the transportation process from both ends to the center. When the output power of the air pump remains unchanged, the airflow velocity and flow direction at each location in the upper and lower channels remain stable, and the airflow velocity at each location tends to be consistent, providing the same degree of air drying effect to the rice noodles at each location. Since the airflow always provides air drying effect to the rice noodles during the flow in the upper and lower channels, compared with the airflow that passes through the seal in the prior art and no longer participates in the air drying effect, the effective utilization rate of air blowing energy consumption is higher, and the airflow is concentrated in the upper and lower channels, and there is no invalid air blowing range, which further improves the effective utilization rate of air blowing energy consumption. On the front side of the center of the upper partition, the airflow direction in the upper and lower channels is opposite to the direction of movement of the rice noodles, and there is an additional relative movement speed between the airflow and the rice noodles, which helps to improve the air drying efficiency. Since the direction of airflow movement tends to be parallel to the length direction of the rice noodles, the lateral thrust generated on the rice noodles is small, which helps to prevent the rice noodles from bending due to wind blowing. Combination Figure 4 As shown, when the distance between the local rice noodles is too close or in contact, the airflow can push them apart, which helps to avoid the rice noodles from contacting and sticking together, and the airflow speed at the position where the distance is closer is greater, which helps to improve the air drying efficiency of the rice noodles at that location and avoid adhesion when bending and contacting again. Under the effect of the screen separation on the upper belt surface of the belt body, the airflow entering the upper channel from the lower channel is dispersed, and the lower surface of the rice noodles is blown at the same time, which helps to improve the uniformity of blowing at various locations on the surface of each rice noodle.

DETAILED DESCRIPTION

[0030] Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same figure numbers in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings need not be drawn to scale unless otherwise specified. The special word "exemplary" here means "used as an example, embodiment or illustrative". Any embodiment described here as "exemplary" is not necessarily interpreted as being superior to or better than other embodiments. In addition, in order to better illustrate the present application, those skilled in the art should understand that numerous specific details are given in each embodiment below. Without certain specific details, the present application can also be implemented. In some embodiments, methods, means and elements well known to those skilled in the art are not described in detail to highlight the subject matter of the present application.

[0031] Combination Figures 1 to 3As shown, the embodiment of the present application provides a rice noodle conveyor belt, including a belt body 100, an active roller 102, a driven roller 104, a side plate 106, and a motor. The belt body 100 is wound around the active roller 102 and the driven roller 104 arranged horizontally side by side. The active roller 102 and the driven roller 104 are located between two vertically arranged side plates 106 and the two ends are rotatably connected to the two side plates 106 respectively. The motor is fixedly installed on one of the side plates 106 and is connected to the active roller 102 through a gear set. It also includes an upper partition 108, a lower partition 110, and an air pump 112. The belt body 100 is configured as a wire mesh. The belt body 100 has a belt-shaped structure, wherein an upper partition 108 is arranged in parallel and spaced relationship above the upper belt surface of the belt body 100 and is fixedly connected between the two side plates 106, and a lower partition 110 is arranged in parallel and spaced relationship below the upper belt surface of the belt body 100 and is fixedly connected between the two side plates 106; an upper channel 114 parallel to the conveying direction is formed between the upper partition 108 and the upper belt surface of the belt body 100, and a lower channel 116 parallel to the conveying direction is formed between the lower partition 110 and the upper belt surface of the belt body 100; an air pump 112 is fixedly connected to the center position of the upper surface of the upper partition 108, and an air inlet of the air pump 112 is connected to the upper channel 114.

[0032] The rice noodle conveyor belt in this embodiment is located between the rice noodle extrusion and stripping station and the rice noodle cutting station during the application process, and the rice noodles are transported from the rice noodle extrusion and stripping station to the rice noodle cutting station. After the rice noodles are extruded from the extrusion and stripping station, they fall on the upper belt surface of the belt body 100. During the transportation process, the rice noodles (such as Figure 2 The air pump 112 draws air from the center of the upper channel 114, causing the air pressure in the central area of ​​the upper channel 114 to drop, and the external air is sucked in from both ends of the upper airway and the lower airway. The airflow blows the rice noodles in the process of transportation from both ends to the center. When the output power of the air pump 112 remains unchanged, the airflow velocity and flow direction at various locations in the upper channel 114 and the lower channel 116 remain stable, and the airflow velocity at various locations tends to be consistent, providing the same degree of air drying effect to the rice noodles at various locations. Since the airflow always provides air drying effect to the rice noodles during the flow process in the upper channel 114 and the lower channel 116, compared with the airflow in the prior art that passes through the seal and no longer participates in the air drying effect, the effective utilization rate of air blowing energy consumption is higher, and the airflow is concentrated in the upper channel 114 and the lower channel 116, and there is no invalid air blowing range, which further improves the effective utilization rate of air blowing energy consumption. At the center front side of the upper partition 108, the airflow direction in the upper channel 114 and the lower channel 116 is opposite to the direction of movement of the rice noodles. There is an additional relative movement speed between the airflow and the rice noodles, which helps to improve the air drying efficiency. Since the airflow direction is parallel to the length direction of the rice noodles, the lateral thrust on the rice noodles is small, which helps to prevent the rice noodles from bending due to wind. Figure 4 As shown, local rice flour (such as Figure 2When the distance between the upper and lower channels 114 is too close or in contact, the airflow can push them away, which helps to avoid the rice noodles from contacting and sticking, and the airflow speed at the position closer is greater, which helps to improve the air drying efficiency of the rice noodles at that place and avoids adhesion when bending and contacting again. Under the effect of the upper belt surface screen separation of the belt body 100, the airflow entering the upper channel 114 from the lower channel 116 is dispersed, and the lower surface of the rice noodles is blown at the same time, which helps to improve the uniformity of blowing at various places on the surface of each rice noodle.

[0033] In some exemplary embodiments of the present embodiment, the rice noodle conveyor belt also includes a plurality of rollers 118, the rollers 118 are horizontally arranged and perpendicular to the conveying direction, the rollers 118 are arranged along the conveying direction, a groove 120 corresponding to the roller 118 is provided on the upper surface of the lower partition 110, the roller 118 is located in the groove 120, the top surface of the roller 118 is located outside the groove 120 and in contact with the upper belt surface of the belt body 100, the two ends of the roller 118 are rotatably connected to the inner wall of the groove 120, and the distance between the lower partition 110 and the upper belt surface of the belt body 100 is smaller than the distance between the upper partition 108 and the upper belt surface of the belt body 100.

[0034] The roller 118 is used to support the upper belt surface of the belt body 100, so that the distance between the upper belt surface of the belt body 100 and the upper and lower partitions 110 tends to be consistent at all locations in the conveying direction, thereby improving the stability and consistency of the airflow at all locations. Since the airflow moving in the front-to-back direction in the lower channel 116 is hindered by the wire mesh on the upper belt surface of the belt body 100, the effective utilization rate of the airflow moving in the lower channel 116 is lower than that in the upper channel 114. Therefore, the distance between the lower partition 110 and the belt surface of the belt body 100 is smaller than the distance between the upper partition 108 and the belt surface of the belt body 100, which helps to increase the airflow speed in the front-to-back direction in the upper channel 114 and improve the effective utilization rate of energy consumption.

[0035] Combination Figure 5 As shown, in some exemplary embodiments of the present embodiment, a plurality of forward-inclined guide bars 122 and backward-inclined guide bars 124 are horizontally fixedly connected to the lower surface of the upper partition 108, and the forward-inclined guide bars 122 and the backward-inclined guide bars 124 are arranged at intervals in the conveying direction, and the forward-inclined guide bars 122 and the backward-inclined guide bars 124 are inclined relative to the conveying direction and in opposite directions of inclination, one end of the forward-inclined guide bar 122 is in contact with the first side panel 106, and the other end of the forward-inclined guide bar 122 is spaced apart from the second side panel 106, one end of the backward-inclined guide bar 124 is spaced apart from the first side panel 106, and the other end of the backward-inclined guide bar 124 is in contact with the second side panel 106, and the forward-inclined guide bar 122 and the backward-inclined guide bar 124 divide the upper part of the upper channel 114 into an S shape.

[0036] The forward-inclined guide strip 122 and the backward-inclined guide strip 124 are used to guide the airflow moving forward and backward at the upper portion of the upper channel 114, so that the rice noodles are not only subjected to the wind blowing effect in the forward and backward directions, but also subjected to the lateral wind blowing effect. Since the lateral wind blowing effect force on the same rice noodles is repeatedly alternating, the rice noodles will not be deflected to one side, which helps to improve the uniformity of air drying of the rice noodles at various locations. Preferably, one end of the forward-inclined guide strip 122 and the backward-inclined guide strip 124 are horizontally rotatably connected to the side plate 106, and the S-shaped shape of the upper portion of the upper channel 114 can be adjusted by rotating the forward-inclined guide strip 122 and the backward-inclined guide strip 124, thereby adjusting the degree of lateral wind blowing effect on the rice noodles.

[0037] In some exemplary implementations of this embodiment, the front end of the lower partition 110 is aligned with the front end of the upper partition 108 , and the rear end of the lower partition 110 is located in front of the rear end of the upper partition 108 .

[0038] When the airflow moves in the upper channel 114, it encounters resistance from obstacles such as rice noodles. The longer the path, the greater the kinetic energy consumption. The shorter the path at the rear of the upper channel 114, the more it helps to eliminate the inconsistency in the relative movement speed between the front and rear airflows and the rice noodles.

[0039] In some exemplary implementations of the present embodiment, a notch 126 extending vertically through the lower partition 110 is provided, and the notch 126 is located at the front side of the center of the upper partition 108 .

[0040] When the lengths of the airflow paths at the front and rear ends of the upper channel 114 are the same, the relative movement speed of the front airflow and the rice noodles is greater. The notch 126 can relieve part of the air pressure at the front of the upper channel 114, which helps to eliminate the inconsistency in the relative movement speeds of the front and rear airflows and the rice noodles, while increasing the blowing effect on the lower surface of the rice noodles passing over the notch 126.

[0041] Combination Figure 6 As shown, in some exemplary implementations of this embodiment, a grid plate 138 is fixedly connected in the notch 126, and the grids of the grid plate 138 are arranged to be inclined relative to the conveying direction.

[0042] The grid can disperse the airflow in the lower space, and improve the consistency of the degree of blowing on the lower surface of each rice noodle. The grid is tilted, which helps to extend the wind exposure time of each rice noodle in the process of passing over the gap 126.

[0043] Combination Figure 7 As shown, in some exemplary implementations of this embodiment, a mesh cover 128 is fixedly connected to the lower surface of the upper partition 108 , and the air inlet of the air pump 112 is located inside the mesh cover 128 .

[0044] The mesh cover 128 can disperse the airflow entering the air inlet of the air pump 112 to prevent the rice noodles from being sucked up due to the low air pressure in the area facing the air inlet of the air pump 112.

[0045] In some exemplary implementations of the present embodiment, the center of the mesh surface of the mesh cover 128 is located directly below the air inlet of the air pump 112, a wind shield 130 is fixedly connected to the center position of the mesh surface of the mesh cover 128, and the mesh density of the mesh cover 128 gradually decreases in the direction away from the center of the cover surface of the mesh cover 128.

[0046] In some exemplary implementations of this embodiment, the air outlet of the air pump 112 is connected to a dehumidification box 132 , and the dehumidification box 132 is filled with a moisture-proof medium.

[0047] In some exemplary implementations of this embodiment, the exhaust port of the dehumidification box 132 is connected to an air duct 136, the air outlet of the air duct 136 extends to directly below the notch 126, and the air outlet of the air duct 136 is provided with a conical expansion port 134, and the conical expansion port 134 is arranged upward.

[0048] The moisture-proof medium can use moisture-proof beads to concentrate the water vapor evaporated from the rice noodles to reduce the impact on the working environment. Part of the exhausted airflow participates in the wind blowing effect on the rice noodles, which helps to improve the effective utilization rate of energy consumption.

[0049] It should be noted that the “upper, lower, front, and rear” in this embodiment refer to the viewing directions in the accompanying drawings. Figure 1 As shown by the straight arrow with a direction, the "transmission direction" in this embodiment is from back to front, that is, the upper belt surface of the belt body 100 moves forward, and the dotted line with an arrow in the figure represents the movement path of the airflow.

Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
