Description

Technical Field

[0001] This utility model relates to the field of toast packaging production technology, specifically a conveying mechanism for toast packaging. Background Technology

[0002] In toast production lines, the conveyor mechanism is the core equipment connecting the baking and packaging processes. Its operational stability and adaptability directly affect production efficiency and packaging quality. However, with the development of the food industry, toast production is moving towards large-scale and multi-specification production. Existing conveyor mechanisms have many shortcomings: poor adjustment flexibility, fixed guiding structures, and inability to adapt to toast specifications, packaging equipment feeding height, and production line layout. Changing toast varieties or adjusting processes requires large-scale equipment modifications, increasing downtime and costs. Conveyor belt tension adjustment often uses manual levers or counterweights, which have low precision and are prone to loosening, leading to conveyor belt slippage and deviation, causing toast to be transported off-center, fall, and damaged. At the same time, the power transmission system lacks stability, easily causing jerking and uneven force on the toast, affecting its appearance. Some mechanisms have fixed angles for diversion and guiding components, making it impossible to flexibly allocate toast flow according to the number of packaging stations, thus restricting the improvement of production efficiency. Therefore, those skilled in the art provide a conveyor mechanism for toast packaging to solve the problems mentioned in the background art. Utility Model Content

[0003] The purpose of this invention is to provide a conveying mechanism for toast packaging to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A conveying mechanism for toast packaging includes a frame, with multiple sets of support legs fixedly connected to the lower surface of the frame, conveyor rollers rotatably connected to the inner side wall of the frame, a conveyor belt disposed between the conveyor rollers, a housing fixedly connected to the bottom of the frame, a transmission mechanism for driving the conveyor belt disposed inside the housing, symmetrically arranged telescopic rods fixedly connected to the upper surface of the frame, a crossbeam fixedly connected to the movable end of the telescopic rods, multiple sets of sliding sleeves slidably connected to the surface of the crossbeams, a damping shaft fixedly connected to the lower surface of the sliding sleeves, and a diverting guide plate fixedly connected to one end of the damping shaft.

[0005] Furthermore, the telescopic rod has a threaded connection on its side wall to a set bolt for limiting the movable end of the telescopic rod.

[0006] Furthermore, the surface of the sliding sleeve is also provided with a threaded groove, and a first bolt rod is threadedly connected to the inner side wall of the threaded groove, and a knob is fixedly connected to the top of the first bolt rod.

[0007] Furthermore, a limiting component is fixedly connected to the inner side wall of the housing, a movable shaft is slidably connected to the inner side wall of the limiting component, and a second bolt rod is rotatably connected to the side wall of the limiting component, and the second bolt rod is threadedly connected to the movable shaft.

[0008] Furthermore, a tension roller is rotatably connected to one end of the movable shaft, and an auxiliary roller and a drive roller are rotatably connected to the inner side wall of the housing. The telescopic conveyor belt passes through the auxiliary roller, the drive roller, and the tension roller in sequence.

[0009] Furthermore, the inner wall of the housing is rotatably connected to a first synchronous pulley and a second synchronous pulley, and a synchronous belt is provided between the first synchronous pulley and the second synchronous pulley.

[0010] Furthermore, a servo motor is fixedly connected to the inner wall of the housing. The power output end of the servo motor is fixedly connected to the shaft end of the first synchronous wheel, and one end of the second synchronous wheel is fixedly connected to the shaft end of the drive roller.

[0011] By adopting the above technical solution Compared with the prior art, the beneficial effects of this utility model are: 1. This mechanism achieves adjustable beam height through the cooperation of telescopic rods and set bolts, adapting to the feeding height requirements of different toast types. The sliding connection between the sliding sleeve and the beam, combined with the angle adjustment function of the damping shaft, allows the lateral position and tilt angle of the diversion guide plate to be flexibly adjusted according to the toast specifications and the number of packaging stations. It can quickly respond to the production needs of multiple varieties and batches, effectively shortening equipment adjustment time and improving production efficiency. All adjustment components are fixed by bolt positioning, making operation simple and easy to understand. Operators do not need professional skills to complete the adjustment of height, tension, and diversion direction.

[0012] 2. The servo motor, combined with synchronous pulleys and belts, ensures smoother power transmission and more precise transmission ratios. This effectively avoids jerking and slippage during power transmission, ensuring uniform conveyor belt speed. This stable transmission characteristic reduces the shaking and collision of toast during transport, protecting its appearance and reducing product loss. A threaded transmission structure using a second bolt rod and movable shaft enables tension adjustment. Compared to traditional pull rods or counterweights, this method offers higher adjustment precision and allows for fine-tuning based on the actual slack of the conveyor belt. Limiting components strictly constrain the sliding trajectory of the movable shaft, preventing the tension roller from shifting during adjustment and ensuring uniform and stable conveyor belt tension. This effectively prevents conveyor belt slippage and deviation, guaranteeing accurate toast transport positioning and ensuring precise alignment for subsequent packaging processes. The transmission and tensioning mechanisms are integrated into the housing at the bottom of the frame, protecting internal components from dust and debris while also making the overall structure more compact, saving floor space in the production workshop and improving the rationality of the workshop layout.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4This utility model provides an embodiment of a conveying mechanism for toast packaging, including a frame 2. Multiple sets of support legs 1 are fixedly connected to the lower surface of the frame 2. Conveying rollers 3 are rotatably connected to the inner wall of the frame 2, and a conveyor belt 4 is arranged between the conveying rollers 3. A housing 5 is fixedly connected to the bottom of the frame 2, and a transmission mechanism for driving the conveyor belt 4 is arranged inside the housing 5. Symmetrically arranged telescopic rods 6 are fixedly connected to the upper surface of the frame 2. A crossbeam 8 is fixedly connected to the movable end of the telescopic rod 6. Multiple sets of sliding sleeves 9 are slidably connected to the surface of the crossbeam 8. A damping rotating shaft 10 is fixedly connected to the lower surface of the sliding sleeve 9. One end of shaft 10 is fixedly connected to a diversion guide plate 11. The side wall of the telescopic rod 6 is threaded with a set bolt 7 for limiting the movable end of the telescopic rod 6. A threaded groove 12 is also provided on the surface of the sliding sleeve 9. A first bolt rod 13 is threadedly connected to the inner side wall of the threaded groove 12. A knob 14 is fixedly connected to the top of the first bolt rod 13. According to the feeding height requirements of different toast types, the set bolt 7 on the side wall of the telescopic rod 6 can be loosened, pushing the crossbeam 8 to move along the axis of the telescopic rod 6 until the height of the crossbeam 8 matches the toast height. Then, the set bolt 7 is tightened to limit and fix the movable end of the telescopic rod 6. The height of the diversion guide plate 11 is adjusted by loosening the first bolt rod 13 on the surface of the sliding sleeve 9 and pushing the sliding sleeve 9 to slide along the surface of the crossbeam 8. This adjusts the lateral position of the diversion guide plate 11. The diversion guide plate 11 can be manually rotated to adjust its tilt angle using the damping characteristics of the damping shaft 10. Once the position and angle are adjusted, the knob 14 is turned to screw the first bolt rod 13 into the threaded groove 12 and tighten it against the crossbeam 8, thus fixing the sliding sleeve 9. This guides the toast to flow along a preset direction to different packaging stations. The telescopic rod 6 and the locking screw... The bolt 7 enables the height of the crossbeam 8 to be adjustable, adapting to the feeding height requirements of different toast types. The sliding connection between the sliding sleeve 9 and the crossbeam 8, combined with the angle adjustment function of the damping shaft 10, allows the lateral position and tilt angle of the diversion guide plate 11 to be flexibly adjusted according to the toast specifications and the number of packaging stations. This enables a rapid response to the production needs of multiple varieties and batches, effectively shortening equipment adjustment time and improving production efficiency. All adjustment components are fixed by bolt positioning, making operation simple and easy to understand. Operators can complete the adjustment of height, tension, and diversion direction without professional skills.

[0017] In this embodiment, a limiting member 15 is fixedly connected to the inner side wall of the housing 5. A movable shaft 16 is slidably connected to the inner side wall of the limiting member 15. A second bolt rod 17 is rotatably connected to the side wall of the limiting member 15, and the second bolt rod 17 is threadedly connected to the movable shaft 16. A tension roller 18 is rotatably connected to one end of the movable shaft 16. An auxiliary roller 19 and a drive roller 20 are also rotatably connected to the inner side wall of the housing 5. The telescopic conveyor belt 4 passes through the auxiliary roller 19, the drive roller 20, and the tension roller 18 in sequence. A first synchronous pulley 22 and a second synchronous pulley 23 are also rotatably connected to the inner side wall of the housing 5. A synchronous belt 24 is provided between the first synchronous pulley 22 and the second synchronous pulley 23. A servo motor 21 is also fixedly connected to the inner side wall of the housing 5. The power output end of the servo motor 21 is fixedly connected to the shaft end of the first synchronous pulley 22, and one end of the second synchronous pulley 23 is fixedly connected to the shaft end of the drive roller 20.After the servo motor 21 starts, its power output end drives the first synchronous pulley 22, which is fixed on the same axis, to rotate. The first synchronous pulley 22 transmits power to the second synchronous pulley 23 through the synchronous belt 24. Since the second synchronous pulley 23 is fixedly connected to the shaft end of the drive roller 20, it drives the drive roller 20 to rotate. The drive roller 20 drives the conveyor belt 4 to run through friction with the conveyor belt 4. At the same time, the auxiliary roller 19 provides support and guidance for the conveyor belt 4, so that the conveyor belt 4 is stably transmitted along the track formed by the conveyor roller 3. The toast placed on the conveyor belt 4 is thus directionally transported. When tension becomes loose after long-term operation or needs to be adjusted according to the weight of the toast, the second bolt rod 17 on the side wall of the limiting member 15 is rotated. Since the second bolt rod 17 is threadedly connected to the movable shaft 16, and the movable shaft 16 can only slide in a straight line under the constraint of the limiting member 15, the rotation of the second bolt rod 17 will be converted into axial movement of the movable shaft 16. The tension roller 18, which is fixed at one end of the movable shaft 16, moves synchronously with the movable shaft 16. By changing the relative distance between the tension roller 18 and the active roller 20 and the auxiliary roller 19, the tension of the conveyor belt 4 can be precisely adjusted to ensure the conveyor belt's stability. Belt 4 maintains a suitable tension at all times. Through the transmission method of servo motor 21 in conjunction with synchronous pulley and synchronous belt 24, power transmission is smoother and the transmission ratio is more precise. This effectively avoids jerking and slippage during power transmission, ensuring that conveyor belt 4 moves at a uniform speed. This stable transmission characteristic reduces the shaking and collision of toast during transmission, protecting the integrity of the toast's appearance and reducing product loss. Tension adjustment is achieved using a threaded transmission structure of the second bolt rod 17 and movable shaft 16. Compared to traditional pull rods or counterweights, this method offers higher adjustment precision and can be adjusted according to the tension of conveyor belt 4. The actual slack is finely adjusted. The limiting component 15 strictly constrains the sliding trajectory of the movable shaft 16, preventing the tension roller 18 from shifting during adjustment. This ensures uniform and stable tension of the conveyor belt 4, effectively preventing slippage and deviation of the conveyor belt 4, guaranteeing the accuracy of the toast conveying position, and providing a guarantee for precise docking of subsequent packaging processes. The transmission mechanism and tensioning mechanism are integrated into the housing 5 at the bottom of the frame 2, protecting the internal components from dust and debris, making the overall structure more compact, saving floor space in the production workshop, and improving the rationality of the workshop layout.

[0018] According to the feeding height requirements of different toast types, loosen the set bolts 7 on the side wall of the telescopic rod 6, push the crossbeam 8 to move along the axis of the telescopic rod 6 until the height of the crossbeam 8 matches the height of the toast. Then tighten the set bolts 7 to limit and fix the movable end of the telescopic rod 6. The height adjustment of the crossbeam 8 completes the height adjustment of the diversion guide plate 11. For different diversion requirements, loosen the first bolt rod 13 on the surface of the sliding sleeve 9, push the sliding sleeve 9 to slide along the surface of the crossbeam 8, and adjust the lateral position of the diversion guide plate 11. Through the damping characteristics of the damping shaft 10, the diversion guide plate 11 can be manually rotated to adjust its tilt angle. When the position and angle are adjusted to the correct position, turn the knob 14 to drive the first bolt rod 13 into the threaded groove 12 and tighten it against the crossbeam 8 to fix the sliding sleeve 9, thereby guiding the toast to flow to different packaging stations along the preset direction. After the servo motor 21 starts, its power output end drives the first synchronous pulley 22, which is fixed on the same axis, to rotate. The first synchronous pulley 22 transmits power to the second synchronous pulley 23 through the synchronous belt 24. Since the second synchronous pulley 23 is fixedly connected to the shaft end of the drive roller 20, it drives the drive roller 20 to rotate. The drive roller 20 drives the conveyor belt 4 to run through friction with the conveyor belt 4. At the same time, the auxiliary roller 19 supports and guides the conveyor belt 4, so that the conveyor belt 4 is stably transmitted along the track formed by the conveyor roller 3. The toast placed on the conveyor belt 4 is thus directionally transported. When the conveyor belt 4 loosens after long-term operation... When the tension needs to be adjusted according to the weight of the toast, the second bolt rod 17 on the side wall of the limiting member 15 is rotated. Since the second bolt rod 17 is threadedly connected to the movable shaft 16, and the movable shaft 16 can only slide in a straight line under the constraint of the limiting member 15, the rotation of the second bolt rod 17 will be converted into the axial movement of the movable shaft 16. The tension roller 18, which is fixed at one end of the movable shaft 16, moves synchronously with the movable shaft 16. By changing the relative distance between the tension roller 18 and the active roller 20 and the auxiliary roller 19, the tension of the conveyor belt 4 can be precisely adjusted to ensure that the conveyor belt 4 always maintains a suitable tension.

[0019] This mechanism achieves adjustable height of the crossbeam 8 through the cooperation of the telescopic rod 6 and the set bolt 7, adapting to the feeding height requirements of different toast types. The sliding connection between the sliding sleeve 9 and the crossbeam 8, combined with the angle adjustment function of the damping shaft 10, allows the lateral position and tilt angle of the diversion guide plate 11 to be flexibly adjusted according to the toast specifications and the number of packaging stations. This enables rapid response to the production needs of multiple varieties and batches, effectively shortening equipment adjustment time and improving production efficiency. All adjustment components are fixed by bolt positioning, making operation simple and easy to understand. Operators do not need professional skills to complete the adjustment of height, tension, and diversion direction. Through the transmission method of the servo motor 21, synchronous pulley, and synchronous belt 24, power transmission is smoother and the transmission ratio is more precise, effectively avoiding jerking and slippage during power transmission and ensuring that the conveyor belt 4 moves at a uniform speed. This stable transmission characteristic This design reduces shaking and collisions of the toast during transport, protecting its appearance and reducing product loss. The tension adjustment is achieved through a threaded transmission structure using the second bolt rod 17 and the movable shaft 16. Compared to traditional pull rods or counterweights, this method offers higher adjustment precision and allows for fine-tuning based on the actual slack of the conveyor belt 4. The limiting component 15 strictly constrains the sliding trajectory of the movable shaft 16, preventing the tension roller 18 from shifting during adjustment. This ensures uniform and stable tension on the conveyor belt 4, effectively preventing slippage and misalignment, guaranteeing the accuracy of the toast's transport position, and providing a guarantee for precise alignment with subsequent packaging processes. The transmission mechanism and tensioning mechanism are integrated into the housing 5 at the bottom of the frame 2, protecting internal components from dust and debris while also making the overall structure more compact, saving floor space in the production workshop, and improving the rationality of the workshop layout.
