[0013] Beneficial effects

[0014] The utility model provides a turning machine that can achieve a micro-joint gap. Compared with the existing technology, it has the following advantages:

[0015] (1) The turning machine that can achieve micro-joint gap, by turning the adjustment knob and through the mutual cooperation of the synchronous wheel and the synchronous belt, the two adjustment threaded rods rotate synchronously, thereby driving the support frame to move. When the support frame moves, the position of the fixed shaft and the small roller inside the special-shaped belt is changed, and the special-shaped belt is extended forward or retracted backward, thereby adjusting the position of the linear conveyor. Since the diameter of the small roller is small, the joint gap between the special-shaped belt and the linear conveyor can be minimized.

[0016] (2) The turning machine that can achieve micro-joint gap, when the small roller and the small roller are adjusted backward, the movable frame pulls the tensioning roller backward under the action of the spring contraction force, thereby pulling the special-shaped belt part to fold backward. Its main function is to make autonomous adjustments when the position of the adaptive fixed axis and the small roller of the special-shaped belt changes. At the same time, it can keep the special-shaped belt at a certain tightness, thereby reducing the friction coefficient of the special-shaped belt and improving the service life of the device.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] This utility model provides two technical solutions:

[0026] Figures 1-6 The first embodiment is shown: a turning machine capable of achieving a micro-joint gap, comprising a base 1, a conveying mechanism 2 disposed on top of the base 1 for conveying materials, an adjusting mechanism 3 symmetrically disposed inside the conveying mechanism 2 for adjusting the belt joint gap, a tensioning mechanism 4 symmetrically disposed inside the conveying mechanism 2 for tensioning the belt, and a supporting mechanism 5 disposed inside the conveying mechanism 2 for supporting the belt;

[0027] The adjustment mechanism 3 includes two brackets 31 fixedly mounted on the top of the base 1, a crossbeam 32 is fixedly connected between the outer surfaces of the two brackets 31, an adjusting threaded rod 33 is symmetrically threaded through the outer surface of the crossbeam 32, and the ends of the two adjusting threaded rods 33 are fixedly mounted with synchronous wheels 34, a synchronous belt 35 is arranged between the two synchronous wheels 34, an adjusting knob 36 is fixedly mounted on the end of one of the synchronous wheels 34, a support frame 37 is threadedly arranged between the two adjusting threaded rods 33, a fixed shaft 38 is arranged between the inner walls of the support frame 37, and a plurality of small rollers 39 are movably sleeved on the outer surface of the fixed shaft 38. When the special-shaped belt 21 is rotating, a plurality of small rollers 39 can be used to adapt to the speed of different areas of the special-shaped belt 21 to avoid deviation.

[0028] The conveying mechanism 2 includes a special-shaped belt 21, and a conical cylinder 22 is symmetrically arranged inside the special-shaped belt 21. A driving shaft 23 is fixedly installed at both ends of the conical cylinder 22. A bearing seat 24 is rotatably arranged on the outer surface of the driving shaft 23. The bearing seat 24 is fixedly installed on the top of the base 1, and the rotation of the conical cylinder 22 can drive the special-shaped belt 21 to run.

[0029] By turning the adjusting knob 36 and through the mutual cooperation of the synchronous wheel 34 and the synchronous belt 35, the two adjusting threaded rods 33 rotate synchronously, thereby driving the support frame 37 to move. When the support frame 37 moves, the position of the fixed shaft 38 and the small roller 39 inside the special-shaped belt 21 is changed, and the special-shaped belt 21 is extended forward or retracted backward, thereby adjusting the position of the linear conveyor. Since the diameter of the small roller 39 is small, the docking gap between the special-shaped belt 21 and the linear conveyor can be minimized.

[0030] Figures 1-6 The second embodiment is shown, which mainly differs from the first embodiment in that the tensioning mechanism 4 includes an L-shaped fixing frame 41 fixedly mounted on the top of the base 1, and two arc-shaped guide rods 42 are movably penetrated on the outer surface of the L-shaped fixing frame 41, and a movable frame 43 is fixedly connected between the ends of the two arc-shaped guide rods 42, and a tensioning roller 44 is rotatably arranged between the inner walls of the movable frame 43, and a spring 45 is provided on the outer sleeve of the arc-shaped guide rod 42, one end of the spring 45 is fixedly connected to the L-shaped fixing frame 41, and the other end of the spring 45 is fixedly connected to the movable frame 43, and when the movable frame 43 moves, it plays a role of guiding and limiting the movable frame 43 through the arc-shaped guide rod 42, and the supporting mechanism 5 includes a plurality of legs 53 fixedly mounted on the top of the base 1, and the top of the legs 53 is fixedly connected to the bottom of the base 1. The top of the support plate 51 is in contact with the inner top of the special-shaped belt 21. Two side stops 52 are provided at the top of the support plate 51 near the edge. The support plate 51 is provided to support the special-shaped belt 21 to prevent the special-shaped belt 21 from collapsing. The side stops 52 can effectively prevent the material from being thrown out due to inertia. The conveying mechanism 2 also includes a drive motor 25 fixedly mounted on the top of the base 1. The output end of the drive motor 25 is fixedly connected to the end of one of the drive shafts 23. By starting the drive motor 25, the conical cylinder 22 is driven to rotate. The outer surface of the small roller 39 is in contact with the inner wall of the special-shaped belt 21, and the outer surface of the tensioning roller 44 is in contact with the outer wall of the special-shaped belt 21.

[0031] Under the action of the contraction force of the spring 45, the movable frame 43 pulls the tensioning roller 44 to move backward, thereby pulling the special-shaped belt 21 to partially fold backward. Its main function is to autonomously adjust the special-shaped belt 21 when the position of the adaptive fixed shaft 38 and the small roller 39 changes. At the same time, it can keep the special-shaped belt 21 at a certain tightness, thereby reducing the friction coefficient of the special-shaped belt 21 and improving the service life of the device.

[0032] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0033] When in use, by turning the adjusting knob 36, and through the mutual cooperation of the synchronous wheel 34 and the synchronous belt 35, the two adjusting threaded rods 33 rotate synchronously, thereby driving the support frame 37 to move. When the support frame 37 moves, the position of the fixed shaft 38 and the small roller 39 inside the special-shaped belt 21 is changed, and the special-shaped belt 21 is extended forward or retracted backward, thereby adjusting the position of the linear conveyor. Since the diameter of the small roller 39 is small, the docking gap between the special-shaped belt 21 and the linear conveyor can be minimized. When the small roller 39 and the small roller 39 are adjusted backward, the movable frame 43 pulls the tensioning roller 44 backward under the action of the contraction force of the spring 45, thereby pulling the special-shaped belt 21 partially folded backward. Its main function is to enable the special-shaped belt 21 to adjust itself when the position of the adaptive fixed shaft 38 and the small roller 39 changes. At the same time, it can keep the special-shaped belt 21 at a certain tightness, thereby reducing the friction coefficient of the special-shaped belt 21 and improving the service life of the device.
