Description

Technical Field

[0001] This utility model relates to the field of packaging machinery technology, and in particular to a multi-stage conveying biscuit packaging device. Background Technology

[0002] The multi-stage conveyor biscuit packaging device is an automated equipment that integrates multiple independent conveyor units and packaging function modules. It can sequentially complete the process of receiving, sorting (such as removing damaged biscuits and adjusting their arrangement), and accurately conveying biscuits to the packaging stage after production. Then, it can complete the entire packaging process, including bagging, sealing, and printing. Each unit can be adapted to different biscuit shapes and sizes through speed adjustment and sensor linkage. Its core function is to improve efficiency by seamlessly connecting the production and packaging stages, reduce biscuit damage by optimizing the conveyor structure, adapt to diverse packaging needs by adjusting parameters, and reduce costs by replacing manual labor while ensuring packaging standardization. It is a key piece of equipment connecting production and packaging in the large-scale production of biscuits. The multi-stage conveyor biscuit packaging device mainly consists of a conveying system, a sorting mechanism, a packaging module, and a control system. The conveying system comprises three independent units: the front section uses a food-grade silicone conveyor belt to receive biscuits, with photoelectric sensors to remove damaged items; the middle section features an arc-shaped transition structure that arranges the biscuits into a predetermined formation using adjustable-gap baffles; and the rear section connects to the packaging machine's feed inlet, with a synchronous belt controlling the conveying rhythm. The sorting mechanism includes a vibrating screen and positioning pushers to ensure uniform biscuit posture and achieve automated integration from production to packaging.

[0003] However, existing multi-segment conveyor biscuit packaging devices suffer from several drawbacks. Firstly, the conveyor belt tension adjustment is inconvenient. Secondly, some incubation rooms employ traditional fixed structural designs with fixed connections between components, relying on custom dimensions. Over time, this leads to conveyor belt loosening, necessitating replacement and significantly increasing capital investment. Thirdly, the assembly of some products is overly cumbersome, severely hindering the rapid replacement and application of the multi-segment conveyor biscuit packaging device. Therefore, this paper proposes a multi-segment conveyor biscuit packaging device to address these issues. Utility Model Content

The adjacent sides of the two housings 31 are fixedly connected to the opposite sides of the two supports 2. The interior of each housing 31 is fixedly connected to a fixing plate 32, which is used to fix the toothed plate 33 so that it can move up and down in a specified position. The toothed plate 33 is slidably connected inside the two fixing plates 32. The toothed plate 33 is used to receive the rotation of the gear 35 to slide up and down. The inner side of the two toothed plates 33 is fixedly connected to a pressure shaft 34, which is used to adjust the tension of the conveyor belt 4. The inner walls of the adjacent sides of the two housings 31 are rotatably connected to the gears 35. The opposite sides of the two gears 35 are fixedly connected to an operating component 36.

[0019] Reference Figures 2 to 4 The cleaning mechanism 5 includes two straight plates 51. The adjacent sides of the two straight plates 51 are fixedly connected to the outside of the support leg 1. The inner sides of the two straight plates 51 are each threaded with two nuts 52. The distant sides of the two straight plates 51 are each fixedly connected with two telescopic slots 53. The telescopic slots 53 are used to lock the buckles 54. The outer sides of the two telescopic slots 53 are each fixedly connected with buckles 54. The outer sides of the two buckles 54 are fixedly connected with scrapers 55. The bottom end of the straight plate 51 is fixedly connected with a trash can 57. The adjacent sides of the two supports 2 are fixedly connected with abutments 56. The abutments 56 allow the scrapers 55 to make large-area contact with the conveyor belt 4.

[0020] Reference Figures 2 to 4The control assembly 36 includes two control levers 361, which are used to rotate and adjust the tension of the conveyor belt 4. The adjacent sides of the two control levers 361 are fixedly connected to the distant sides of the two gears 35. The exterior of each control lever 361 is slidably connected to a door 363. The interior of each distant side of the two housings 31 is slidably connected to a recessed card 362. The interior of each housing 31 is fixedly connected to two fixed shafts 364.

[0021] The top ends of the two fixed shafts 364 are slidably connected to the outside of the conveyor belt 4. The fixed conveyor belt 4 moves together with the pressure shaft 34. The outer side of the box door 363 is fixedly connected to the inner side of the outer shell 31. The adjacent sides of the two outer shells 31 are fixedly connected to the outside of the support leg 1. The bottom end of the pressure shaft 34 is slidably connected to the outside of the conveyor belt 4. The bottom end of the abutment 56 is slidably connected to the inner wall of the conveyor belt 4. The top end of the scraper 55 is slidably connected to the outside of the conveyor belt 4, so that the scraper 55 removes the residual garbage on the conveyor belt 4.

[0022] The outer end of the abutment 56 is fixedly connected to the inner wall of the bracket 2 to fix the position of the abutment 56. The top of the trash can 57 is fixedly connected to the outer side of the support leg 1. The trash can 57 stores the trash scraped off the conveyor belt 4 by the scraper 55 to avoid inconvenience in subsequent cleaning. The inner side of the recessed card 362 is slidably connected to the inside of the box door 363. The recessed card 362 slides on the box door 363 to move it to the toothed plate 33 and lock the toothed plate 33. The outer side of the toothed plate 33 is meshed with the outer side of the gear 35.

[0023] Working principle: When the tension of the conveyor belt 4 needs to be adjusted, the control lever 361 is turned to rotate the gear 35 connected to it. The gear 35 rotates and meshes with the toothed plate 33 connected to it. The fixed plate 32 fixes the toothed plate 33 and makes it move up and down. The pressure shaft 34 is fixedly connected to the other side of the toothed plate 33. The pressure shaft 34 presses the conveyor belt 4 downward. The fixed shaft 364 is fixedly connected to the rear side of the housing 31. The position of the conveyor belt 4 is above the fixed shaft 364 and below the pressure shaft 34. When the pressure shaft 34 descends, it pulls the conveyor belt 4 downward, making the conveyor belt 4 taut and producing a tension adjustment effect. When the conveyor belt 4 is taut, the locking clip 362 slides onto the gear 35, so that the locking clip 362 locks onto the gear 35 to prevent the gear 35 from rotating backward. When the conveyor belt 4 needs to be adjusted or replaced, the locking clip 362 is slid away from the gear 35, and then the control lever 361 is used to adjust the gear 35.

[0024] When the conveyor belt 4 is in a stationary cleaning state, align the clip 54 of the scraper 55 with the gap between the two telescopic slots 53 on the side of the support leg 1, and insert it axially to the locking position to quickly fix the scraper 55 assembly. During the operation of the conveyor belt 4, the scraper 55 maintains a moderate contact with the surface of the conveyor belt 4 through the squeezing action of the abutment 56, achieving a continuous self-cleaning effect. The dynamic contact angle between the scraper 55 blade and the conveyor belt 4 has been optimized to significantly improve cleaning efficiency and reduce wear. When the scraper 55 is worn and needs to be replaced, the operator only needs to pull out the clip 54 to remove the entire scraper 55 assembly from the telescopic slots 53 for replacement.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
