Abstract
Description
Technical Field
[0001] This utility model relates to the field of quick-freezing machine technology, specifically a novel coupling mechanism between the rotating hub column and the curved beam of a quick-freezing machine. Background Technology
[0002] Spiral freezers currently hold approximately 75%-80% of the domestic market share in the quick-freezing industry. Compared to other types of freezers such as tunnel freezers, IQF freezers, plate freezers, and box freezers, they possess absolute advantages (in terms of quick-freezing effect and cost-effectiveness). Spiral freezers are non-standard equipment with complex and varied structures. The internal components of this equipment involve many profiles and sheet metal. The manufacturing process involves a series of processes such as laser cutting, bending, grinding, drilling, welding, and pickling. After final packaging, the parts are shipped to the site, where professional construction personnel assemble the equipment according to the drawings, conduct debugging, trial production, and training, and finally deliver the equipment to the customer for use.
[0003] In existing equipment, the connection between the column and the curved beam is traditionally achieved by fixing a connecting plate. This method requires the connecting plate to be laser-cut, drilled, ground, and precision-ground before being placed on the end face of the square tube. It is then positioned according to a measuring tape, followed by argon arc welding. After welding, the weld seam is cleaned, and finally, the tube is placed on a straightening platform to correct any areas deformed by the welding. This structure is complex and cumbersome, resulting in a long processing time and increased costs. Furthermore, after the column is welded, factors such as welding stress deformation and uneven weld seam affect the overall appearance of the equipment.
[0004] Based on this, this solution proposes a novel coupling mechanism between the rotating hub column and the curved beam of a quick-freezing machine. Utility Model Content
[0005] The purpose of this invention is to provide a novel coupling mechanism between the rotating drum column and the curved beam of a quick-freezing machine, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel coupling mechanism between the rotating hub column and the curved beam of a quick-freezing machine, comprising a square tube,
[0007] The top of the square tube is welded with a top plate and multiple supporting cantilever arms are fixedly welded at equal intervals at the front end of the square tube. Multiple supporting guide bars are fixedly welded to the top of any supporting cantilever arm, and the top of the corresponding multiple supporting guide bars is provided with the same transmission mesh belt.
[0008] Two connecting plates are fixedly welded to both sides of the square tube. Two threaded holes are opened on each connecting plate. A curved beam is provided on one side of each connecting plate. Two fixing plates are fixedly welded to each curved beam. A round hole is opened on each fixing plate. The same bolt is installed in the corresponding threaded hole and the round hole.
[0009] Preferably, each bolt is fitted with a flat washer and an elastic washer.
[0010] Using the above technical solution, the flat washer on the bolt is mainly used to protect the fixing plate from damage, while the elastic washer is used to prevent loosening and bolts from coming loose. The elastic washer increases the friction between the bolt and the fixing plate through its own elasticity, thereby achieving the effect of preventing loosening. The flat washer and the elastic washer are used together to simultaneously achieve the functions of protecting the components and preventing bolts from loosening.
[0011] Preferably, an operating block is fixedly installed on any of the connecting plates, and through holes are opened at the top and bottom of any of the operating blocks. Two rotating shafts are rotatably installed inside any of the operating blocks. A vertical rod is movably installed in any of the through holes. A connecting rod and a clamping block are fixedly installed at both ends of any of the vertical rods, respectively. A gear and a pressing elliptical wheel are fixedly sleeved on any of the rotating shafts. A locking bolt is threaded on one side of any of the operating blocks. A double-sided rack is rotatably installed at one end of any of the locking bolts. A knob is fixedly sleeved on the other end of any of the locking bolts.
[0012] Using the above technical solution, rotating the corresponding knob inward to lock the corresponding locking bolt inward, the locking bolt pushes the corresponding double-sided rack to move inward, the double-sided rack drives the rotation of the corresponding two gears, which in turn drives the rotation of the corresponding two extrusion elliptical wheels. The extrusion elliptical wheels extrude the corresponding connecting rods, which in turn drives the corresponding vertical rod to move outward, which in turn drives the vertical movement of the corresponding clamping block. The clamping block can clamp the corresponding bolt, which can further reduce the loosening of the bolt.
[0013] Preferably, a return spring is sleeved on each vertical rod, one end of each return spring is fixed to the corresponding vertical rod, and the other end of each return spring is fixed to the inner wall of the corresponding through hole.
[0014] By adopting the above technical solution, the return spring facilitates the reset of the vertical rod.
[0015] Preferably, each operating block is fixedly installed with a slide rail, each slide rail is slidably installed with a slider, and each slider is fixedly connected to a corresponding double-sided rack.
[0016] The above technical solution facilitates the movement of the double-sided rack through the slide rail and slider.
[0017] Preferably, the square tube, connecting plate, and supporting cantilever form a hub column.
[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: First, by argon arc welding four connecting plates to the square tube, the round holes of the fixing plates on the curved beam are aligned with the corresponding threaded holes, and then the bolts are threaded into the corresponding threaded holes and round holes to fix the curved beam and the square tube. The flat washers on the bolts are mainly used to protect the fixing plates from damage, while the elastic washers are used to prevent loosening and bolt detachment. The elastic washers increase the friction between the bolts and the fixing plates through their own elasticity, thereby achieving the effect of preventing loosening. The flat washers and elastic washers are used together to simultaneously protect the components and prevent bolt loosening. Compared with the original complex welding method, this method is more efficient and efficient. Factors such as welding stress deformation and uneven weld seams affect the overall appearance of the equipment. Bolt installation is more convenient and cost-effective. To enhance the anti-loosening effect of the bolts, the corresponding locking knob can be turned inward to push the corresponding locking bolt inward. The locking bolt pushes the corresponding double-sided rack inward, which drives the rotation of the corresponding two gears, thereby driving the rotation of the corresponding two extrusion elliptical wheels. The extrusion elliptical wheels extrude the corresponding connecting rods, thereby driving the corresponding vertical rod outward, which in turn drives the vertical movement of the corresponding clamping block. The clamping block can clamp the corresponding bolts, further reducing bolt loosening. This utility model has a simple structure and is easy to use. The novel coupling mechanism of the rotating hub column and curved beam of the quick-freezing machine, which uses bolt installation, greatly shortens the processing cycle and reduces processing costs, while still meeting the strength requirements. After installation, the overall appearance is also greatly improved, which provides great help for the sustainable production of the spiral quick-freezing machine. Attached Figure Description

[0026] 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.
[0027] Please see Figure 1-6 This utility model provides a technical solution: a novel coupling mechanism for the rotating drum column and curved beam of a quick-freezing machine, including a square tube 1. A top plate 3 is welded to the top of the square tube 1, and multiple supporting cantilever arms 7 are fixedly welded at equal intervals at the front end of the square tube 1. The number of supporting cantilever arms 7 is generally 6-30. Multiple supporting guide bars 5 are fixedly welded to the top of each supporting cantilever arm 7. A common transmission mesh belt 4 is provided on the top of the corresponding multiple supporting guide bars 5. Two connecting plates 6 are fixedly welded to both sides of the square tube 1. Two threaded holes are provided on each connecting plate 6. A curved beam 2 is provided on one side of each connecting plate 6. Two fixing plates 8 are fixedly welded to each curved beam 2. A round hole is provided on each fixing plate 8. The same bolt 9 is installed in the corresponding threaded hole and the round hole. A flat washer 12 and an elastic washer 13 are fitted onto each bolt 9. With the above structural setup, the four connecting plates 6 are first fixed to the square tube 1 by argon arc welding. The round holes of the fixing plates 8 on the curved beam 2 are aligned with the threaded holes on the corresponding plates 6. Then, the bolts 9 are threaded into the corresponding threaded holes and round holes to fix the curved beam 2 and the square tube 1. The flat washers 12 on the bolts 9 are mainly used to protect the fixing plates 8 from damage. The elastic washers 13 are used to prevent loosening and prevent the bolts 9 from coming loose. The elastic washers 13 increase the friction between the bolts 9 and the fixing plates 8 through their own elasticity, thereby achieving the effect of preventing loosening. The flat washers 12 and elastic washers 13 are used together to simultaneously protect the components and prevent the bolts 9 from loosening. Compared with the original complex welding method, which caused welding stress deformation and uneven welds, affecting the overall appearance of the equipment, bolt installation is more convenient and saves costs.
[0028] Combination Figure 1-6As shown, an operating block 10 is fixedly installed on any of the connecting plates 6. Each operating block 10 has through holes at its top and bottom, and two rotating shafts 18 are rotatably installed inside each operating block 10. A vertical rod 19 is movably installed inside each of the through holes. A connecting rod 21 and a clamping block 14 are fixedly installed at both ends of each vertical rod 19. A gear 16 and a pressing elliptical wheel 15 are fixedly sleeved on each of the rotating shafts 18. A locking bolt 22 is threaded onto one side of each operating block 10. A double-sided rack 17 is rotatably installed at one end of each locking bolt 22. A knob 11 is fixedly sleeved at the other end of each locking bolt 22. A return spring 20 is sleeved on each vertical rod 19. One end of each return spring 20 is fixed to the corresponding vertical rod 19, and the other end is fixed to... On the inner wall of the corresponding through hole, a slide rail is fixedly installed in any one of the operating blocks 10, and a slider is slidably installed on any one of the slide rails. Each slider is fixedly connected to the corresponding double-sided rack 17. With the above structure, in order to increase the anti-loosening effect of the bolt 9, the corresponding locking bolt 22 can be pushed to lock inward by rotating the corresponding knob 11 inward. The locking bolt 22 pushes the corresponding double-sided rack 17 to move inward. The double-sided rack 17 drives the rotation of the corresponding two gears 16, which in turn drives the rotation of the corresponding two extrusion elliptical wheels 15. The extrusion elliptical wheels 15 extrude the corresponding connecting rod 21, which drives the corresponding vertical rod 19 to move outward, which in turn drives the vertical movement of the corresponding clamping block 14. The clamping block 14 can clamp the corresponding bolt 9, which can further reduce the loosening of the bolt 9.
[0029] The working principle of this utility model is as follows: First, four connecting plates 6 are argon-arc welded and fixed to the square tube 1. Then, the round holes of the fixing plates 8 on the curved beam 2 are aligned with the corresponding threaded holes on the 6. Finally, bolts 9 are threaded into the corresponding threaded holes and round holes, thus fixing the curved beam 2 to the square tube 1. The flat washer 12 on the bolt 9 primarily protects the fixing plate 8 from damage, while the elastic washer 13 prevents loosening and detachment of the bolt 9. The elastic washer 13 increases the friction between the bolt 9 and the fixing plate 8 through its own elasticity, thereby achieving the anti-loosening effect. The flat washer 12 and the elastic washer 13 work together to simultaneously protect the components and prevent the bolt 9 from loosening. This method is superior to the welding stress caused by the original complex welding method. Deformation and uneven welds affect the overall appearance of the equipment. Bolt installation is more convenient and cost-effective. To enhance the anti-loosening effect of bolt 9, the corresponding locking knob 11 can be turned inward to push the corresponding locking bolt 22 inward. The locking bolt 22 pushes the corresponding double-sided rack 17 inward, which drives the rotation of the corresponding two gears 16, thereby driving the rotation of the corresponding two extrusion elliptical wheels 15. The extrusion elliptical wheels 15 extrude the corresponding connecting rods 21, thereby driving the corresponding vertical rod 19 outward, which in turn drives the vertical movement of the corresponding clamping block 14. The clamping block 14 can clamp the corresponding bolt 9, further reducing the loosening of bolt 9. This utility model has a simple structure and is easy to use. The novel coupling mechanism of the quick-freezing machine hub column and curved beam, which is bolted, greatly shortens the processing cycle and reduces processing costs, while still meeting the strength requirements. After installation, the overall appearance is also greatly improved, which provides great help for the sustainable production of the spiral quick-freezing machine.
