Description

Technical Field

[0001] This utility model relates to the field of automated food processing equipment technology, specifically to a double-chain plate conveying device based on gear and rack drive. Background Technology

[0002] The double-chain pallet tray stacking machine is a specialized piece of equipment in the food processing industry used to automatically stack shaped foods (such as pastries, hamburger patties, etc.) onto trays according to preset arrangement rules. Its core function is to achieve efficient and precise food arrangement through the coordinated action of the chain conveyor mechanism and the tray stacking mechanism. The tray stacking machine's conveying device, as the material transfer module of this equipment, is mainly responsible for transporting the trays that have been stacked on the tray stacking machine body to the subsequent packaging process. Its performance directly affects the overall production efficiency and tray stacking consistency of the machine.

[0003] Traditional tray-laying machines typically use chain drives or cylinders to position and transfer trays, but these methods have significant limitations. Firstly, ordinary chain drives are prone to insufficient positioning accuracy (often ≥2mm error) due to chain elasticity, making them unsuitable for high-precision tray arrangement. Secondly, while rack and pinion drives can improve positioning accuracy, in food processing environments, the meshing gap between the rack and pinion easily accumulates food debris, grease, and other contaminants, leading to increased wear and reduced transmission stability over time, highlighting dust and contamination issues. Furthermore, existing tray-laying machines and conveying mechanisms are mostly fixed, integrated designs, making it impossible to adjust their relative positions according to production line layouts, resulting in poor flexibility. Therefore, a high-precision, easy-to-clean, and modular tray-laying machine conveying device is urgently needed. Utility Model Content

[0004] The purpose of this invention is to provide a conveying device for a double-chain plate tray stacking machine based on gear and rack drive. Through the integrated design of gear and rack precision drive and double-chain plate synchronous conveying, it solves the problems of low positioning accuracy of traditional chain drive, easy contamination of gear and rack, and rigid connection between tray stacking machine and conveying mechanism, thereby improving tray stacking efficiency and production line adaptability.

[0005] The technical solution provided by this utility model is a double-chain plate tray conveying device based on gear and rack drive, including a tray conveying machine body and a conveying mechanism located on one side of the tray conveying machine body;

[0006] The tray-arranging machine body is located on one side of the conveying mechanism and is slidably connected to a movable plate via a guide rail. The movable plate slides to send the trays on the tray-arranging machine body to the conveying mechanism on one side.

[0007] The movable plate is fixedly connected to a rack on the outside of the guide rail. A drive gear meshes with the bottom of the rack. The drive gear drives the meshing rack to move, so that the movable plate connected to the rack slides along the guide rail.

[0008] The tray-laying machine body is equipped with a conveyor belt and an adjustable belt drive system for driving the conveyor belt;

[0009] The conveying mechanism includes two parallel food-grade chain plates, which are symmetrically installed on the conveying mechanism and move synchronously on both sides.

[0010] As a preferred technical solution of this utility model, the adjustable belt drive system includes a drive roller, multiple guide rollers and an adjusting roller, wherein the drive roller and multiple guide rollers are all disposed inside the body of the tray winding machine, and the adjusting rollers are located at both ends of the movable plate. The conveyor belt is wound around the drive roller, guide rollers and adjusting rollers, and the multiple guide rollers and the adjusting rollers are located at the drive gear and rack to form an S-shaped adjustable belt telescopic structure.

[0011] As a preferred embodiment of this utility model, the upper surface of the tray-arranging machine body is at the same horizontal plane as the upper surface of the movable plate, and the conveyor belt arranged above is also arranged parallel to the upper surface of the movable plate.

[0012] As a preferred embodiment of this utility model, the movable plate is located above the conveying mechanism, and the length of the movable plate extending out of the main body of the tray-laying machine is greater than or equal to the width of the conveying mechanism.

[0013] As a preferred technical solution of this utility model, the two ends of the chain plate are driven by chain plate gears, and the two chain plate gears are connected by a transmission shaft. A servo motor for driving is connected to one end of the transmission shaft.

[0014] As a preferred embodiment of this utility model, the tray-forming machine body and the conveying mechanism are separately configured, and the relative positions of the conveying mechanism and the tray-forming machine body can be adjusted as needed.

[0015] As a preferred embodiment of this utility model, the contact surfaces of the rack and the guide rail are coated with a wear-resistant coating, which is made of polytetrafluoroethylene.

[0016] The advantages of this utility model compared with the prior art are as follows:

[0017] 1. High-precision positioning: The gear and rack drive replaces the traditional chain or cylinder, and the gear and rack transmission accuracy can reach ±0.1mm, effectively solving the problem of insufficient positioning accuracy of chain drive;

[0018] 2. Synchronous conveying stability: The double chain plate, through its symmetrical layout and synchronous drive design of chain plate gear-drive shaft-servo motor, ensures uniform force distribution during pallet conveying and avoids deviation or tilting.

[0019] 3. Modular flexibility: The tray tray machine body and the conveying mechanism are set separately, and the relative positions can be adjusted to adapt to different specifications of trays or production line space constraints;

[0020] 4. Dust and dirt prevention optimization: The contact surface between the rack and the guide rail is coated with polytetrafluoroethylene, which has both low friction and anti-fouling properties, reducing the accumulation of food crumbs and extending the maintenance cycle of the drive system;

[0021] 5. Adaptive belt length: The S-shaped telescopic structure of the adjustable belt drive system compensates for belt length changes when the movable plate slides by adjusting the rollers, thus preventing belt slack or breakage. Attached Figure Description

The tray conveying machine body 1 and the conveying mechanism 2 are set separately, and the relative position of the conveying mechanism 2 and the tray conveying machine body 1 can be adjusted as needed.

[0031] In this utility model, the tray arranging machine body 1 is located on one side of the conveying mechanism 2 and is slidably connected to a movable plate 3 via a guide rail. The movable plate 3 is located above the conveying mechanism 2, and the length of the movable plate 3 extending out of one side of the tray arranging machine body 1 is greater than or equal to the width of the conveying mechanism 2. The trays on the tray arranging machine body 1 are sent to the conveying mechanism 2 on one side by sliding the movable plate 3.

[0032] In this utility model, a rack 4 is fixedly connected to the outer side of the movable plate 3 and the bottom of the rack 4 is engaged with a drive gear 5. The drive gear 5 drives the engaged rack 4 to move, so that the movable plate 3 connected to the rack 4 slides along the guide rail. The contact surfaces of the rack 4 and the guide rail are coated with a wear-resistant coating of polytetrafluoroethylene material.

[0033] In this utility model, the tray-laying machine body 1 is provided with a conveyor belt 6 and an adjustable belt drive system for driving the conveyor belt 6. The adjustable belt drive system includes a drive roller 8, multiple guide rollers 9 and an adjusting roller 10. The drive roller 8 and multiple guide rollers 9 are all located inside the tray-laying machine body 1, and the adjusting roller 10 is located at both ends of the movable plate 3. The conveyor belt 6 is wound around the drive roller 8, guide rollers 9 and adjusting roller 10. The multiple guide rollers 9 and adjusting roller 10 are located at the drive gear 5 and rack 4 to form an S-shaped adjustable belt telescopic structure. The upper end face of the tray-laying machine body 1 is at the same horizontal plane as the upper end face of the movable plate 3, and the conveyor belt 6 above is also parallel to the upper end face of the movable plate 3.

[0034] In this utility model, the conveying mechanism 2 includes two parallel food-grade chain plates 7, which are symmetrically installed on the conveying mechanism 2 and move synchronously on both sides.

[0035] As per the instruction manual Figure 3 As shown, the two ends of the chain plate 7 are driven by the meshing of the chain plate gears 11, and the two chain plate gears 11 are connected by a transmission shaft 12. A servo motor 13 for driving is connected to one end of the transmission shaft 12.

[0036] Working principle

[0037] 1. Pallet conveying stage: The conveyor belt 6 installed on the main body 1 of the pallet arranging machine conveys the food pallet to the top of the movable plate 3 (the movable plate 3 is flush with the upper surface of the main body 1 of the pallet arranging machine).

[0038] 2. Precise positioning stage: Drive gear 5 starts, and through rack 4, drives movable plate 3 to slide along guide rail towards conveyor mechanism 2, pushing the pallet from the pallet stacking station to above conveyor mechanism 2 (the extended length of movable plate 3 covers the width of conveyor mechanism 2); or after the pallet is sent from the pallet stacking station to above conveyor mechanism 2, drive gear 5 drives rack 4 to move quickly in the opposite direction, sending movable plate 3 back from conveyor mechanism 2, and the pallet stays in place and falls onto the double chain plate 7 of conveyor mechanism 2 below under gravity;

[0039] 3. Pallet transfer stage: After the movable plate 3 is in place, the double chain plate 7 of the conveying mechanism 2 is started, and the servo motor 13 drives the gears 11 on both sides of the chain plate to rotate synchronously through the transmission shaft 12, transferring the pallet from the movable plate 3 to the end of the conveying process.

[0040] 4. Cyclic operation stage: The movable plate 3 is reset (slids to the left) under the reverse rotation of the drive gear 5, and the above steps are repeated to complete the continuous tray conveying.

[0041] The present invention and its embodiments have been described above. This description is not restrictive, and the specific embodiments shown are only one of the embodiments of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
