Description

Technical Field

[0001] This invention relates to the field of modular belt sorting machines, specifically an ultra-low resistance swing arm type modular belt sorting conveyor that automatically calibrates the discharge of goods. Background Technology

[0002] The rocker arm type module sorter places the items to be sorted on the conveyor. When they reach the sorting port, the rocker arm rotates and the items slide along the inclined plane of the rocker arm to the designated destination. At the same time, it can continuously and in large quantities sort goods. In addition, the rocker arm type sorter has high sorting efficiency. Therefore, the sorting capacity of the rocker arm type sorter is several times that of the workload of the manual sorting system.

[0003] Modular conveyor belts installed on sorting machine conveyor belts, also known as modular mesh or mesh belts, are conveyor belts made of plastic thermoplastic molding into semi-finished modules, which are then assembled according to requirements and installed on conveyors to carry and transport materials. Currently, modular conveyor belts involve sorting objects during transport, requiring the classification and sorting of objects of different specifications. In the current use of swing-arm modular conveyor belts, some excessively long objects are prone to obstruction during sorting, causing all subsequent objects to be blocked. The interrupted sorting process leads to the need for secondary sorting of subsequent objects. Summary of the Invention

[0004] The purpose of this invention is to provide an ultra-low resistance swing arm modular belt sorting conveyor with automatic calibration of cargo discharge, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An ultra-low resistance swing arm type modular sorting conveyor with automatic calibration of cargo discharge includes a support frame, a conveyor belt frame is fixedly connected to the top of the support frame, a motor is installed at the power input end of the conveyor belt frame, an inner roller is installed at the drive end of the motor, and a conveyor belt module is drivenly connected to the outer wall of the inner roller. A cylinder is provided on one side of the motor. A hinge seat is installed on the outer wall of the cylinder. The hinge seat is fixedly connected to the outer wall of the support frame. A hinge arm is hinged to the telescopic end of the cylinder. A rotating shaft is sleeved on the front end of the hinge arm. A connecting shaft is fixedly connected to the top of the rotating shaft. A rear frame is fixedly connected to the top of the connecting shaft. A front frame is slidably connected to the front end of the rear frame. A retraction mechanism is installed between the back of the front frame and the front frame of the rear frame. The conveyor belt module includes module one and module two. Module one has a recessed groove at one end near module two. Module two has a protruding piece fixedly connected to one end near the recessed groove. The protruding piece and the recessed groove are connected by a pin. Both module two and module one have shaft holes on their outer walls for inserting the pin. Both module one and module two have protruding seats installed inside their frames. Knurled pins are installed on the outer walls of the protruding seats, with one end penetrating the outer wall of the protruding seat and fitted with a ball bearing. The shrinking mechanism includes a cavity one. A displacement block is slidably connected to the inner cavity of cavity one. A cavity three is fixedly connected to the bottom of cavity one. A cavity two is fixedly connected to the bottom of cavity three. A rack is fixedly connected to the bottom end of the displacement block. The lower part of the outer wall of the rack... The retraction mechanism includes a gear, a drive shaft is fixedly connected to the shaft center of the gear, and a base is mounted on the bottom of the gear. Displacement blocks are mounted on the front and rear parts of the upper surface of the base. The bottom of the displacement blocks penetrates the upper surface of the base and is mounted on a connecting plate. An extension cap is mounted on the bottom shaft center of the connecting plate. The rack and the extension cap are on the same vertical horizontal plane. A locking cylinder is mounted on one end of the drive shaft. A hinge rod is hinged to the outer wall of the locking cylinder. The hinge rod is hinged to the outer wall of the base. An extension shaft is fixedly connected to the end of the locking cylinder away from the drive shaft. A worm gear is fixedly connected to the front end of the extension shaft. A turbine gear is meshed on the outer wall of the worm gear. A vertical shaft is fixedly connected to the bottom shaft center of the turbine gear. A bearing column is mounted on the bottom of the vertical shaft.

[0006] As a further embodiment of the present invention: a transmission roller is installed on the inner frame of the front frame, and a transmission roller pin is installed on the axial part of the transmission roller, and the transmission roller pin is rotatably connected to the upper and lower ends of the front frame.

[0007] As a further embodiment of the present invention: the discharge part on the platform of the conveyor belt frame is fixedly connected to a mounting frame, and there are two sets of mounting frames, with rollers rotatably connected to the two sets of mounting frames facing opposite sides.

[0008] Compared with the prior art, the beneficial effects of the present invention are: In this invention, when an object is positioned between the front end of the front frame and the rollers at the small object material location, the conveyor belt module exerts a thrust on the front frame, causing it to move towards the front end slot of the rear frame. This forces a displacement block to move within the inner cavity of the cylinder. The gear connected to the front end of the displacement block moves under the thrust of the displacement block and controls the rotation of the rack meshed with the gear. The drive shaft connected to the rack's central shaft rotates, and the lock cylinder connected to the front end of the drive shaft is fixedly connected to the extension shaft. When the extension shaft rotates, it drives the worm gear to rotate, and the turbine gear meshing with the worm gear rotates. The cap connected to the top of the turbine gear and the rear frame are fixed, thus achieving the overall deflection of the rear frame. This pushes the large object blocking the small material outlet between the two sets of rollers for discharge. The structure is more optimized and the design is more reasonable.

[0009] In this invention, the rotation direction of the balls on the conveyor belt module is arranged longitudinally and transversely with the transmission direction of the conveyor belt module. This facilitates the rolling of large objects on the conveyor belt module between the two sets of rollers for discharge. The protruding seats installed on the sides of the balls reduce the impact of objects on the balls and protect them, while also enhancing the impact resistance of the balls. The installed modules one and two are connected by a recessed groove and a protruding piece. By locking the recessed groove and the protruding piece through the hole of the shaft hole using a set of pins, quick disassembly of modules one and two can be achieved. Attached Figure Description

There are two sets of mounting frames 8. The two sets of mounting frames 8 are rotatably connected to rollers 7 on opposite sides.

[0021] The working principle of this invention is: In use, the object is placed on the conveyor belt module 9, the motor 4 is turned on, and the inner roller 3 is rotated. The conveyor belt module 9, driven by the inner roller 3, operates and conveys the material. When the material is conveyed to the baffle of the front frame 5, it is blocked. The transmission roller 25 installed on the baffle of the front frame 5 is used to convey the object on the baffle. Small objects are discharged through the gap between the shrinking mechanism 15 and the roller 7, while larger objects are conveyed through the gap between the two sets of rollers 7, thus realizing the planning of the object conveying process. The rotation direction of the ball bearings 16 on the conveyor belt module 9 is arranged longitudinally and transversely with the transmission direction of the conveyor belt module 9, which is used to facilitate the rolling of large objects on the conveyor belt module 9 between the two sets of rollers 7 for discharge. The protruding seat 17 installed on the side of the ball bearings 16 reduces the impact of objects on the ball bearings 16 and protects the ball bearings 16, while strengthening the impact resistance of the ball bearings 16. The installed module 1 22 and module 23 are connected by a recessed groove 21 and a protruding piece 20. The recessed groove 21 and the protruding piece 20 are locked in the hole of the shaft hole 19 by a set of pins, which can realize the quick release of module 1 22 and module 23. Before the object is placed onto the conveyor belt module 9, the tilt of the rear frame 6 needs to be adjusted. By controlling the operation of the cylinder 11, the rotating shaft 13, which is hinged to the hinge arm 12, is pulled to rotate, thereby controlling the rotation of the connecting shaft 10 connected to the top of the cylinder 11. The rear frame 6 connected to the top of the connecting shaft 10 will also receive the rotational force and rotate, which is used to adjust the tilt angle of the rear frame 6. However, the problem is that if the object is too long, after blocking the front frame 5, the front end of the object will be located at the small material outlet between the front frame 5 and the roller 7, which will prevent the objects behind from passing through. Based on the above improvements: When the object is positioned between the front end of the front frame 5 and the roller 7, the conveyor belt module 9 will push the front frame 5, causing it to move towards the front end slot of the rear frame 6 and squeeze the displacement block 41 to move within the cavity of the cylinder 35. The gear 37 connected to the front end of the displacement block 41 will move under the thrust of the displacement block 41 and control the rotation of the rack 38 meshed with the gear 37. The drive shaft 33 connected to the shaft end of the rack 38 will rotate. The lock cylinder 32 connected to the front end of the drive shaft 33 and the extension shaft 31 are fixedly connected. When the extension shaft 31 rotates, it will drive the worm 27 to rotate. The turbine 28 meshing with the worm 27 will rotate. The cap 26 connected to the top of the turbine 28 and the rear frame 6 are fixed, which can achieve the overall deflection of the rear frame 6. This will push the large object blocking the small material outlet to the space between the two sets of rollers 7 for discharge. The vertical shaft 29 connected to the bottom of the turbine 28 is rotatably connected to the bearing column 30 at the bottom of the inner frame of the rear frame 6.
