Description

Technical Field

[0001] This utility model relates to the field of belt conveyor technology, specifically a folding belt conveyor for bagged materials. Background Technology

[0002] A folding belt conveyor is a special type of conveyor. It adds a folding section to the basic straight belt conveyor, enabling it to transport materials upwards or downwards, or shorten its length. Upward and downward transport can meet different conveying needs, while shortening the length allows for transport across workshops. When installed next to the fire doors of a workshop, the folding mechanism allows the fire doors to be closed smoothly in the event of a fire, isolating two workshops. It is an important conveying device.

[0003] When using a folding belt conveyor to transport bagged materials, the weight borne on the belt surface is concentrated on the bagged material. In existing technologies, the folding parts of folding belt conveyors are supported by electric or pneumatic push rods. During transport, the push rods need to bear the weight of the folding parts and the bagged material above them, as well as the additional load caused by vibration. Although the push rods have a certain self-locking effect, experience shows that the self-locking effect of the push rods is generally poor and the reliability is not high, which directly affects the stability and reliability of the belt conveyor and raises concerns about its service life. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a folding belt conveyor for bagged materials, which solves the problem that the folding part of the existing folding belt conveyor is supported by push rods, affecting the stability and reliability of the belt conveyor.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A bagged material folding belt conveyor includes a fixed frame, a folding frame movably hinged to one end of the fixed frame, and a support frame fixed below the fixed frame. A motor mounting frame is movably hinged to the bottom of the folding frame via a hinge seat. A gearbox and a lead screw motor are respectively installed on both sides of the motor mounting frame. The lead screw motor is connected to two trapezoidal lead screws through the gearbox.

[0007] The support frame has a fixed seat on the inner side of the support leg, and the fixed seat is rotatably connected to a flipping frame. The flipping frame is equipped with a lead screw nut, and the lead screw nut is installed on a trapezoidal lead screw.

[0008] Preferably, the hinge seat is connected to the top of the motor mounting bracket on the side away from the fixed frame, and the hinge seat is fixed to the lower center of the folding frame.

[0009] Preferably, the motor mounting bracket is an L-shaped bracket, the gearbox is fixed on one side of the motor mounting bracket corresponding to the support bracket, and the lead screw motor is fixedly installed on the side of the motor mounting bracket away from the support bracket.

[0010] Preferably, the two trapezoidal lead screws are arranged parallel to each other and symmetrically front to back below the folding frame.

[0011] Preferably, the fixed base is symmetrically fixed on the support frame, and the flipping frame is rotatably connected to the fixed base through fixed shafts on the front and back sides.

[0012] Preferably, the gearbox includes a main gearbox and two symmetrical auxiliary gearboxes. A drive shaft is installed between the main gearbox and the auxiliary gearboxes. Both ends of the drive shaft are fixed with drive gears. The output shaft of the lead screw motor passes through the motor mounting bracket and the main gearbox and is connected to a drive gear inside the main gearbox. The drive gear meshes with two drive gears at opposite ends of the two drive shafts. A connecting shaft perpendicular to the drive shaft is installed on the auxiliary gearbox. A driven gear that meshes with the drive gear is fixed on the connecting shaft. The connecting shaft is fixedly connected to one end of the trapezoidal lead screw.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The folding frame of this utility model achieves folding, unfolding, and support effects through a lead screw motor and two trapezoidal lead screws. The trapezoidal lead screws have a large angle between their thread direction and the direction of the supporting force, resulting in a good self-locking effect that is significantly higher than that of push rods. The folding frame is supported by two symmetrical trapezoidal lead screws, ensuring stable support and uniform force distribution. It maintains excellent reliability and stability even under heavy transport conditions, solving the problem that the folding part of existing folding belt conveyors is supported by push rods, which affects the stability and reliability of the belt conveyor.

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.

[0021] like Figure 1-4 As shown, this utility model provides a technical solution: a bagged material folding belt conveyor, including a fixed frame 1, a folding frame 2 movably hinged to one end of the fixed frame 1, and a support frame 3 fixed below the fixed frame 1. The bottom of the folding frame 2 is movably hinged to a motor mounting frame 5 via a hinge seat 4. The hinge seat 4 is connected to the top of the motor mounting frame 5 on the side away from the fixed frame 1, and the hinge seat 4 is fixed in the lower middle part of the folding frame 2, providing a uniform and stable support force for the folding frame 2.

[0022] Gearbox 6 and lead screw motor 7 are respectively installed on both sides of motor mounting bracket 5. Motor mounting bracket 5 is an L-shaped bracket. Gearbox 6 is fixed on one side of motor mounting bracket 5 corresponding to support bracket 3, and lead screw motor 7 is fixedly installed on the side of motor mounting bracket 5 away from support bracket 3.

[0023] The lead screw motor 7 is connected to two trapezoidal lead screws 8 through the gearbox 6. The trapezoidal lead screws 8 with a helix angle of less than 5 degrees can achieve a self-locking function to ensure the stable support effect after the folding frame 2 is unfolded. The two trapezoidal lead screws 8 are parallel to each other and symmetrically arranged at the bottom of the folding frame 2. The double lead screw structure is used for support, which gives it higher support structure strength and higher stability.

[0024] The gearbox 6 includes a main gearbox 601 and two symmetrical auxiliary gearboxes 602. A drive shaft 603 is installed between the main gearbox 601 and the auxiliary gearboxes 602. Both ends of the drive shaft 603 are fixed with drive gears 604. The output shaft of the screw motor 7 passes through the motor mounting bracket 5 and the main gearbox 601 and is connected to the drive gear 605 inside the main gearbox 601. The drive gear 605 meshes with the two drive gears 604 at opposite ends of the two drive shafts 603. A connecting shaft 606 perpendicular to the drive shaft 603 is installed on the auxiliary gearbox 602. A driven gear 607 meshing with the drive gears 604 is fixed on the connecting shaft 606. The connecting shaft 606 is fixedly connected to one end of the trapezoidal screw 8.

[0025] A fixed seat 9 is fixed to the inner side of the support leg of the support frame 3. The fixed seat 9 is symmetrically fixed to the support frame 3. The flipping frame 10 is rotatably connected to the fixed seat 9 through the fixed shaft 12 on the front and back. The fixed seat 9 is rotatably connected to the flipping frame 10. A screw nut 11 is installed on the flipping frame 10, and the screw nut 11 is installed on the trapezoidal screw 8.

[0026] Working principle:

[0027] The lead screw motor 7 can synchronously drive the two trapezoidal lead screws 8 to rotate through the gearbox 6. Under the action of the lead screw nut 11, the trapezoidal lead screws 8 support the flipping frame 10, which can push the folding frame 2 to flip upward to complete the unfolding. The angle between the thread direction of the trapezoidal lead screw 8 and the support force direction is large, and the self-locking effect is good. The folding frame 2 is supported by two symmetrical trapezoidal lead screws 8, which makes the support stable and the force even. When the lead screw motor 7 drives the trapezoidal lead screws 8 to flip, it can pull the folding frame 2 to flip downward to achieve the folding effect.
