Description

Technical Field

[0001] The utility model relates to the technical field of conveying equipment, in particular to a multi-stage vibration-dispersing conveying device. Background Art

[0002] In the food packaging industry, braised eggs are popular among consumers for their nutritious and delicious taste. However, a critical step in the production of braised eggs is the package counting process. This process requires not only efficiency and accuracy, but also ensuring that the product meets quality requirements before packaging, such as uniform dispersion and no accumulation.

[0003] Traditional packaging and counting equipment for braised eggs often uses a single conveyor belt or vibrating plate to transport materials. However, this method is prone to problems such as material accumulation and uneven conveying when handling irregularly shaped materials like braised eggs. Material accumulation not only leads to inaccurate counting but can also affect the proper operation of the packaging machine and even damage the product. Furthermore, uneven conveying increases the difficulty and cost of subsequent packaging operations.

[0004] To address these issues, conveying devices with vibration dispersion capabilities have gradually emerged on the market. However, most of these devices utilize a single-stage vibration dispersion design. While this improves material dispersion to a certain extent, it remains insufficient when handling certain specialized materials or demanding packaging tasks. Therefore, it is crucial to develop a multi-stage vibration dispersion conveyor that can disperse materials more effectively and stably, and adapt to diverse packaging requirements.

This device utilizes multiple conveying links, including an intermediate material distribution hopper, a first-stage vibrating conveyor tray, a second-stage vibrating conveyor tray, and a belt conveyor, with the conveying surface heights decreasing in sequence to form a stepped conveying surface. This design not only effectively prevents material accumulation during conveying, but also vibrates and disperses the material at multiple stages, ensuring that the material remains evenly distributed throughout the conveying process, providing a strong guarantee for subsequent counting and packaging operations.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a multi-stage vibrating conveying device, comprising a frame, on which are provided an elevator, an intermediate material distribution hopper, a first-level vibrating conveying disc, a second-level vibrating conveying disc, and a belt conveyor, wherein the conveying surface heights of the intermediate material distribution hopper, the first-level vibrating conveying disc, the second-level vibrating conveying disc, and the belt conveyor decrease in sequence, and the intermediate material distribution hopper, the first-level vibrating conveying disc, the second-level vibrating conveying disc, and the belt conveyor are connected end to end to form a stepped conveying surface.

[0007] In order to further optimize the present invention, the following technical solutions may be preferably used:

The belt conveyor is provided with multiple conveying channels, and the end of each material dividing plate corresponds to a conveying channel.

[0009] Preferably, a plurality of partitions are arranged side by side on the frame above the conveying surface corresponding to the belt conveyor, the partitions are arranged along the conveying direction, and a conveying channel is formed between two partitions, a gantry hanger is provided on the frame at the position corresponding to the partition, an adjustment groove is provided on the upper edge of the gantry hanger perpendicular to the conveying direction, an adjustment rod is provided at the position corresponding to the adjustment groove on the upper part of the partition, a locking nut is provided on the upper end of the adjustment rod passing through the adjustment groove, and the spacing between the partitions is changed by changing the position of the locking nut.

[0010] Preferably, the belt conveyor includes a first belt conveyor and a second belt conveyor connected end to end, and the conveying surface height of the first belt conveyor is higher than the conveying surface height of the second belt conveyor.

[0014] The multi-stage vibration conveying device of the utility model has brought significant beneficial effects in the field of conveying technology in counting and packaging equipment, which are specifically reflected in the following aspects:

[0015] 1) Effectively prevent material accumulation: By designing multiple conveying links, including an intermediate distribution hopper, a first-stage vibrating material tray, and a second-stage vibrating material tray, the conveying surface height decreases in sequence, forming a stepped conveying surface. This allows materials to be dispersed step by step during the conveying process, effectively avoiding the problem of material accumulation in traditional conveying methods. This design ensures smooth material flow and reduces the risk of equipment downtime due to accumulation.

[0016] 2) Improved material dispersion uniformity: The multi-stage vibrating conveyor disperses the material multiple times during the conveying process through the vibration of each stage of the vibrating disc. This multiple dispersion mechanism ensures that the material maintains a high degree of uniformity before reaching the final packaging stage, providing a more stable and reliable material foundation for subsequent counting and packaging operations.

[0017] 3) Improved counting and packaging accuracy: Because materials are fully dispersed and evenly distributed during transportation, they can be more accurately identified and counted when they enter the counting sensor area. This greatly improves counting and packaging accuracy and reduces counting errors and packaging quality issues caused by uneven material distribution.

[0018] 4) Enhanced Equipment Adaptability and Flexibility: This utility model's multi-stage vibrating conveyor can be flexibly adjusted to suit the characteristics and packaging requirements of different materials. For example, by adjusting the vibration frequency and amplitude of each stage of the vibrating conveyor, optimal dispersion of different materials can be achieved. This design enables the device to be widely used in various counting and packaging scenarios, improving the equipment's adaptability and flexibility.

[0019] 5) Improved Production Efficiency and Reduced Costs: By reducing material accumulation, improving dispersion uniformity, and increasing counting accuracy, this multi-stage vibrating conveyor significantly improves the overall operational efficiency of a production line. Furthermore, by reducing downtime and rework costs caused by material issues, the device also helps reduce production and operating costs. BRIEF DESCRIPTION OF THE DRAWINGS

This design ensures the smooth flow of materials and reduces the risk of equipment shutdown due to accumulation.

[0028] As a preferred embodiment, a wavy material dividing plate 7 is installed on the top of the secondary vibration dispersion conveyor disc 5, and the material of the primary vibration dispersion conveyor disc is conveyed in separate columns through the wavy material dividing plate 7. The discharge end of the wavy material dividing plate extends to the belt conveyor. The belt conveyor is equipped with multiple conveying channels, and the end of each material dividing plate corresponds to a conveying channel. The application of the wavy material dividing plate in the secondary vibration dispersion conveyor disc: This design cleverly uses the wave shape to guide the material, so that the material conveyed from the primary vibration dispersion conveyor disc can be conveyed in separate columns through the wavy material dividing plate. The wavy material dividing plate not only helps to further disperse the material, but also ensures that the material remains in an orderly arrangement during the conveying process, reducing intersections and overlaps. Its discharge end extends directly to the belt conveyor, realizing seamless connection of the material from vibration dispersion to conveying.

[0029] As a preferred embodiment, multiple partitions 8 are installed side by side on the frame 1, corresponding to the conveying surface of the belt conveyor. The partitions are arranged along the conveying direction, forming a conveying channel between the two partitions. A gantry hanger 9 is installed on the frame at the corresponding position of the partitions. The gantry hanger has an adjustment slot 10 on its upper edge, perpendicular to the conveying direction. An adjustment rod 11 is installed on the upper part of the partition, corresponding to the adjustment slot. The adjustment rod 11 has an external thread that mates with a lock nut. The upper end of the adjustment rod passes through the adjustment slot and is installed with a lock nut 12. The spacing between the partitions can be adjusted by changing the position of the lock nut. A multi-channel conveying and adjustable partition system: The belt conveyor is innovatively equipped with multiple conveying channels, each corresponding to the end of a wavy material separator. This design allows materials to enter each channel according to a predetermined path and sequence upon arrival at the belt conveyor, further improving the accuracy and efficiency of material conveying. Furthermore, to meet the needs of different materials and packaging, multiple partitions are installed on the frame, corresponding to the conveying surface of the belt conveyor, forming a conveying channel between the partitions. Notably, the position of these partitions is adjustable. Through the adjustment slots on the gantry hanger and the adjustment rods on the partitions, combined with the adjustment of the lock nuts, the spacing between the partitions can be easily changed to adapt to the conveying needs of materials of different sizes and shapes.

[0030] As a preferred embodiment, the belt conveyor includes a first belt conveyor 13 and a second belt conveyor 14 connected end to end, and the conveying surface height of the first belt conveyor is higher than the conveying surface height of the second belt conveyor; Segmented belt conveyor design: As another preferred embodiment, the belt conveyor is designed to be segmented, including a first belt conveyor and a second belt conveyor connected end to end (or more segments, depending on actual needs). This segmented design is not only easy to install and maintain, but also can be flexibly adjusted according to the specific layout of the production line and material transportation requirements. For example, when it is necessary to change the conveying direction or increase the conveying length, the number of sections of the belt conveyor can be easily increased or decreased. In addition, the segmented belt conveyor can also install additional auxiliary equipment on specific sections, such as meters, detection sensors, etc., to further improve the automation and intelligence level of the production line.

Specifically, the linear vibrator can be an electromagnetic silo linear vibrator: HD-ZL200; linear vibrators are installed in both the first-stage vibrating conveyor plate and the second-stage vibrating conveyor plate, and are equipped with a vibrating conveying trough. The linear vibrator can produce stable linear vibrations, and this vibration mode is very effective for the dispersion and transportation of materials. Through the transmission of the vibrating conveying trough, the material can be continuously subjected to uniform vibration during the conveying process, thereby effectively preventing material accumulation and promoting the uniform dispersion of the material. This design not only improves the efficiency of material transportation, but also ensures the accuracy of the material in the subsequent counting and packaging process.

[0032] As a preferred embodiment, a conical dividing plate 16 is installed in the middle of the intermediate distribution hopper 2, which divides the intermediate distribution hopper into multiple chambers 17, and a first-level vibrating conveyor disc corresponds to the bottom of each chamber; the conical dividing plate installed in the middle of the intermediate distribution hopper cleverly divides the distribution hopper into multiple chambers, and a first-level vibrating conveyor disc 4 corresponds to the bottom of each chamber. This design allows the material entering the intermediate distribution hopper from the elevator or other feeding equipment to be first dispersed into each chamber by the conical dividing plate, and then enter the corresponding first-level vibrating conveyor disc respectively. This sub-chamber design not only helps to further disperse the material, but also ensures the uniformity and stability of the material during the transportation process. At the same time, it also improves the processing capacity and flexibility of the equipment, allowing the device to better adapt to different materials and packaging requirements.

[0033] As a preferred embodiment, a bending portion 18 is installed at the discharge end of the first-level vibrating conveyor disc 4, and the bending portion is overlapped at the feed position of the first-level vibrating conveyor disc 4, which can ensure the smoothness of the items to be packaged from the first-level vibrating conveyor disc into the second-level vibrating conveyor disc.
