Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, specifically to a counting device for packaging braised eggs. Background Technology

[0002] Currently, in the packaging production of braised eggs and similar spherical and block-shaped foods, the industry commonly uses weighing to indirectly control the packaging quantity. The core principle of this method is to calculate the theoretical total weight of the corresponding packaging by multiplying the standard weight of a single braised egg by the target packaging quantity. The weight of the braised egg material is then measured using weighing equipment, and a measurement is completed when the material weight reaches the theoretical value. This measurement method, with its simple equipment structure, low initial investment cost, and strong adaptability, has been widely used in the food packaging field, especially in the early stages when braised egg production processes were relatively rudimentary and packaging precision requirements were not high, and it could basically meet the production needs of enterprises.

[0003] However, with the refinement of braised egg production processes and the increasing market demand for standardized product packaging, the inherent defects of traditional weighing and measurement methods have become increasingly apparent, making them unsuitable for the precision requirements of modern braised egg packaging production. This is mainly reflected in the following aspects: First, the accuracy of measurement is easily affected by individual differences in marinated eggs. During the production process, the actual weight of a single marinated egg often fluctuates due to factors such as the size of the raw eggs, the marinating time, and changes in moisture content during marinating. This individual weight deviation is amplified during weighing. For example, if the weight deviation of a single marinated egg is ±2g, and the target packaging quantity is 10 eggs, the total weight deviation can reach ±20g. This results in a difference of 1-2 eggs between the actual packaged quantity and the preset quantity, making accurate counting impossible. This can lead to problems with insufficient or excessive packaging. The former may result in consumer complaints, while the latter will increase the company's production costs.

[0004] Secondly, the condition of the material significantly interferes with the accuracy of measurement. During the conveying process of marinated eggs, if the eggs are stacked, stuck together, or obstructed by gaps in the conveying equipment, the weight of the material entering the weighing area will fluctuate abnormally. The weighing equipment will find it difficult to accurately identify the actual quantity of the material and can only determine whether the measurement has been completed based on the weight signal, further exacerbating the error in the packaging quantity. Utility Model Content

[0005] To address the aforementioned issues, this utility model provides a counting device for packaging braised eggs. It utilizes a conveying trough to disperse the material and then uses a counting module to collect information. Compared to traditional weighing and metering methods, this device can more accurately measure the packaging quantity and reduce packaging errors.

[0006] To achieve the above objectives, this utility model embodiment adopts the following technical solution: a counting device for packaging braised eggs, comprising a frame, a feeding module and a counting module disposed on the frame, the feeding module comprising a mixing bin, a conveying trough disposed at the lower end of the mixing bin, the counting module comprising a housing connected to the frame, a falling channel disposed inside the housing, the upper part of the falling channel being connected to the conveying trough, and a receiving conveyor belt disposed below, and a counting module disposed below the frame and located inside the falling channel.

[0007] As a further improvement to the above technical solution: The counting module includes a mounting base, on which a fixing plate is provided, and an infrared sensor and an image acquisition sensor are provided on the inner side of the fixing plate.

[0008] The upper surface of the mounting base is provided with a guide rail, and a slide for mounting an infrared sensor and an image acquisition sensor is provided on the guide rail. A push rod for moving the slide is provided on the fixing plate.

[0009] The side wall of the falling channel is provided with a through slot corresponding to the position of the counting module.

[0010] The housing is provided with discharge ports located at both ends of the receiving conveyor belt, and a transfer conveyor belt is provided on the outside of the discharge ports.

[0011] The conveying trough includes a dispersing section and a conveying section. The dispersing section is provided with a first distributing trough and a second distributing trough. An infrared sensor is provided above the second distributing trough.

[0012] The first and second material distribution troughs are arranged in a stepped manner along the material conveying direction, and each is equipped with a vibration generator at the bottom.

[0013] Both the first and second material distribution troughs are inclined, with an inclination angle of 3-7 degrees.

[0014] The conveying section is equipped with two stepped feeding conveyor belts, and each of the two feeding conveyor belts is equipped with a conveying channel that connects to the falling channel.

[0015] The beneficial effects of this utility model embodiment are as follows: The counting device for packaging braised eggs includes a frame, on which a feeding module and a counting module are provided.

[0018] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0019] like Figure 1 As shown, the counting device for packaging braised eggs in this embodiment includes a frame 1, on which a feeding module and a counting module are installed. The feeding module is responsible for distributing and conveying the braised eggs, while the counting module counts the number of braised eggs conveyed to the designated area. A receiving conveyor belt 6 is provided below the counting module to receive the braised eggs that have been counted.

[0020] The feeding module uses the batching bin 2 as the material transfer center, and its lower end is connected to the conveying trough 3 for conveying braised eggs. The conveying trough 3 is connected to the upper part of the falling channel 5 of the counting module to form a complete material conveying path.

[0021] The conveying trough 3 is specifically divided into a dispersing section and a conveying section. The dispersing section contains a first distributing trough 17 and a second distributing trough 18. These two troughs are arranged in a stepped pattern along the material conveying direction, enabling layered dispersion of materials and preventing congestion. To enhance the feeding effect, a vibration generator 20 is installed at the bottom of both distributing troughs, and both are designed with an inclination angle of 3-7 degrees, utilizing the combined effects of gravity and vibration to assist material flow. An infrared sensor 29 is also installed above the second distributing trough 18, connected to an external control console. When there is material in the second distributing trough 18, the first distributing trough 17 stops vibrating and feeding. The conveying unit has two stepped material conveyor belts 21 inside. Each material conveyor belt 21 has a corresponding conveying channel 22 above it. The conveying channel 22 is directly connected to the falling channel 5 of the counting module to ensure that the dispersed material can accurately enter the counting module.

[0022] The counting module includes a housing 4 fixedly connected to the frame 1. Inside the housing 4 is a falling channel 5 for material passage. A through groove 14 is formed on the side wall of the falling channel 5, corresponding to the position of the detection component of the counting module. The core structure of the counting module includes a mounting base 7, a fixing plate 8, a detection element, and an adjustment mechanism, as detailed below: A fixing plate 8 is fixed to the upper part of the mounting base 7, and a guide rail 11 is mounted on the upper surface. A slide block 12 is slidably mounted on the guide rail 11, and the two core detection components, infrared sensor 9 and image acquisition sensor 10, are both mounted on the slide block 12. A push rod 13 is also provided on the fixing plate 8, which can drive the slide block 12 to move along the guide rail 11, thereby flexibly adjusting the position of the detection components.

[0023] Infrared sensor 9 works in conjunction with image acquisition sensor 10 to sense and acquire images of the hard-boiled egg during the falling process through the through groove 14 on the side wall of the falling channel 5, thereby achieving dual counting verification and improving counting accuracy.

[0024] After the count is completed, the braised eggs fall through the drop channel 5 into the receiving conveyor belt 6 below. The shell 4 has discharge ports 15 at both ends of the receiving conveyor belt 6. After the receiving conveyor belt 6 transports the braised eggs to the discharge ports 15, they are received by the transfer conveyor belt 16 set outside the discharge ports 15, realizing the subsequent transfer and packaging of the braised eggs.
