Description

TECHNICAL FIELD

[0001] The utility model relates to lotus root powder can production technical field, concretely relates to a kind of lotus root powder canning line. BACKGROUND

[0002] The lotus root powder sold on the market at present is basically dry lotus root powder, which needs to be brewed with boiling water during consumption, and the consumption is relatively troublesome. In view of this situation, some instant lotus root powder with relatively short storage period is developed on the market. Since the instant lotus root powder is lotus root powder that has been gelatinized, new requirements are needed for the packaging equipment in the actual production process. In the production process, this instant lotus root powder basically adopts a design similar to a can, so that in addition to ensuring storage, it can also avoid the internal instant lotus root powder from being extruded and deformed, affecting the taste in the later period.

[0003] Since the instant lotus root powder is basically composed of fresh lotus root powder and water gelatinization, no preservative is added inside, in order to ensure normal storage in the later period, the equipment for filling has very high requirements. At present, the packaging box is generally made of plastic or aluminum plastic material, and when filling lotus root powder in the later period, it must be cleaned and dried one by one, so that bacteria carried in the packaging box can be avoided to cause the filled lotus root powder to deteriorate. In view of this situation, the patent with publication number CN201821972433.3 discloses a new type of high-efficiency packaging box spraying, drying and cleaning machine, which sets an air extractor to suck dust on the surface of the packaging box, achieves a preliminary dust removal effect, sets spray pipes on four sides in the cleaning chamber to comprehensively wash the packaging box, cleans more comprehensively and efficiently, greatly saves labor and cost, sets a air knife assembly in the cleaning chamber to reduce pollution of pure water by detergent, so as to facilitate recycling and recycling of cleaning agent and pure water, save energy and protect the environment. Although the flushing and drying effects are achieved, the spray pipes are arranged above, below and on the side of the conveying mechanism, so that comprehensive flushing is achieved. However, if the packaging box is placed in the positive direction on the conveying mechanism, there will be water accumulation in the packaging box. Even if there is a drying link in the later period, it is difficult to completely remove the water accumulation in the packaging box, which affects the quality of the product in the later period. If the packaging box is placed in the reverse direction on the conveying mechanism, there is no problem of water accumulation. However, the technical solution in the technical scheme does not disclose how to turn over the packaging box for filling in the later period. At the same time, the technical solution only simply discloses the technical solution of cleaning the packaging box, and does not disclose the technical solution of directly filling the packaging box after cleaning to reduce pollution. Based on this, the present application proposes an improvement. UTILITY MODEL CONTENTS

[0026] In order to make the purpose, technical scheme and advantages of the utility model clearer and more apparent, the utility model will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and not to limit the utility model.

[0027] Referring to Figures 1 to 5 The sago canning line shown in the figure comprises a rack 10 and a filling device 20, the rack 10 is provided with a conveying chain belt 30; the rack 10 is provided with a packaging box blanking mechanism 40 at one end of the input of the conveying chain belt 30, the packaging box blanking mechanism 40 can place the packaging boxes on the conveying chain belt 30 one by one; the rack 10 is provided with a flushing mechanism 50 and a drying mechanism 60 in sequence at one end of the output direction of the conveying chain belt 30, the rack 10 is provided with a conveying belt 70 in communication with the conveying chain belt 30, the filling device 20 is installed on the rack 10 at the area corresponding to the conveying belt 70, and the rack 10 is provided with a turnover mechanism 80 for turning over the packaging boxes at the position between the conveying belt 70 and the conveying chain belt 30.

[0028] The main purpose of the conveying chain belt 30 is to enable the flushing mechanism 50 to flush water upward to flush the packaging boxes placed upside down; at the same time, it can also avoid the existence of accumulated water on the conveying chain belt 30. The packaging box blanking mechanism 40 in the present application can adopt the structure in patent CN202121303110.7-A bowl separating mechanism or the structure in CN202222367900.2-A automatic meal box separating and blanking device, which will not be described in detail here. The conveying belt 70 and the conveying chain belt 30 are separately driven by different motors, so as to realize different conveying effects.

[0029] The sago canning line in the present application designs the packaging box blanking mechanism 40, the flushing mechanism 50 and the drying mechanism 60 on the basis of the existing conveying chain belt 30, realizes the purpose of separating, cleaning and drying the packaging boxes one by one. At the same time, another conveying belt 70 is arranged at one end of the output of the conveying chain belt 30, which is suitable for different working requirements and improves the adaptability of the whole production line. In addition, the turnover mechanism 80 for turning over the packaging boxes is arranged at the position between the conveying belt 70 and the conveying chain belt 30, which realizes the turning over of the packaging boxes and the transfer between the conveying chain belt 30 and the conveying belt 70, and facilitates the conveying of the packaging boxes to the filling device 20 for filling.

[0030] Referring to Figures 1 to 2The rinsing mechanism 50 includes a mounting frame 51, a water tank 52, a plurality of nozzles 53 mounted on the mounting frame 51, and a supply pipe 54 for supplying water to the nozzles 53. The mounting frame 51 is mounted on the frame 10 inside the conveyor belt 30. All the nozzles 53 are upwardly oriented and can rinse the packaging boxes conveyed by the conveyor belt 30. The supply pipe 54 is connected to the water tank 52 and is equipped with a supply pump 55. An elastic pressure plate 56 is provided on the frame 10 directly above the area where the nozzles 53 are mounted.

[0031] In the above embodiments, the nozzles 53 are only located at the bottom of the conveyor belt 30, allowing for the rinsing of the packaging boxes with their openings facing downwards. The outer perimeter and back of the packaging boxes can be rinsed as needed; in this application, only the inner walls of the packaging boxes are rinsed. In some embodiments, nozzles can also be located above and on both sides of the conveyor belt 30, allowing for the rinsing of the outer side and back of the packaging boxes as well. In some embodiments, to improve water recovery, a receiving water tank can be located below the conveyor belt 30. Furthermore, to prevent water splashing during rinsing, a waterproof cover can be installed above the nozzles 53, directly connected to the upper part of the receiving water tank, facilitating the flow of water from the waterproof cover into the receiving water tank.

[0032] See Figure 3 In one embodiment of this application, to improve the drying effect, the drying mechanism 60 includes a housing 61, a hot air duct 62, and a hot air blower 63. The housing 61 is mounted on the frame 10 and covers the conveyor belt 30. Openings are provided at both ends of the housing 61 along the conveying direction of the conveyor belt 30, and baffles are hinged to the openings. The hot air duct 62 is located on the inner walls of both sides of the housing 61 along the conveying direction of the conveyor belt 30. The hot air blower 63 is mounted on the housing 61 and communicates with the hot air duct 62. Several nozzles are provided on the side of the hot air duct 62 facing the conveying plane of the conveyor belt 30, and at least a portion of the hot air duct 62 is located below the conveying plane of the conveyor belt 30. The hot air blower 63 directly provides hot air; in effect, the housing 61 is a structure that covers the conveyor belt 30, which reduces hot air loss and improves the drying effect. The baffles effectively prevent the hot air inside the housing 61 from leaking out too quickly.

[0033] See Figure 4In order to facilitate the turning of the packaging box, the traditional mechanical hand mode can be used for turning, but the use cost is high and the turning efficiency is low. In an embodiment of the present application, the turnover mechanism 80 comprises an arc-shaped guide pressing plate 81 and a receiving positioning seat 82. The arc-shaped guide pressing plate 81 is installed on the rack 10 and is concentrically arranged with the rotating center on the output end of the conveying chain belt 30.

The receiving positioning seat 82 can receive the packaging box output by the two bearing guide rods 83. The packaging box on the receiving positioning seat 82 can be conveyed to the filling device 20.

[0034] When the reverse buckling packaging box is conveyed to one end of the arc-shaped guide pressing plate 81 together with the conveying chain belt 30, the packaging box is clamped between the conveying chain belt 30 and the arc-shaped guide pressing plate 81 due to the limiting effect of the arc-shaped guide pressing plate 81 and the conveying effect of the conveying chain belt 30, and can also move together with the conveying chain belt 30. Damping springs are arranged between the arc-shaped guide pressing plate 81 and the rack 10. When the packaging box is clamped and conveyed by the conveying chain belt 30 and the arc-shaped guide pressing plate 81, the packaging box is driven to the space between the conveying chain belt 30 and the bearing guide rod 83. At this time, the packaging box has almost completed the turning, and the packaging box will automatically adjust according to its own gravity and the overall weight will gradually transfer to the two bearing guide rods 83. Since the corresponding end of the two bearing guide rods 83 and the conveying chain belt 30 is eccentrically arranged, and the lower end of the bearing guide rod 83 gradually moves away from the conveying chain belt 30, the packaging box gradually slides on the two bearing guide rods 83 due to its own weight, until it is received by the receiving positioning seat 82. The receiving positioning seat 82 is a turning structure, which is suitable for the input end of the packaging box of the filling device 20.
