Description

A device for auxiliary opening on the outer surface of a dryer shaft Technical Field

[0001] This utility model relates to the field of dryer processing technology, and in particular to an auxiliary hole opening device for the outer surface of a dryer shaft. Background Technology

[0002] The holes in the shaft of the paddle dryer, usually hollow structures with channels, are designed to achieve efficient circulation and uniform heat transfer of the heat medium. The internal cavity of the shaft serves as the main channel for the heat medium (steam, heat transfer oil, etc.), and the heat medium is distributed to each hollow paddle through the holes in the shaft, ensuring that heat is evenly transferred to the paddle surface.

[0003] Currently, multiple holes are usually required on the shaft of a dryer to facilitate the installation of the blades. Since the holes need to be made on the curved surface, the operation is difficult. During the hole-making process, the position between the holes is prone to deviation, which may lead to uneven heat conduction in the dryer. In addition, it is usually necessary to process multiple surfaces of the shaft, which is inconvenient to operate. Therefore, an auxiliary hole-making device for the outer surface of the shaft of a dryer is proposed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an auxiliary opening device for the outer surface of a dryer shaft.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

The lower ring block is connected inside the lower limiting ring. A slot is opened on both ends of the lower ring block. A connecting block is installed on both ends of the upper ring block. The connecting block is movably connected in the slot.

[0009] Preferably, a notch is provided on one side of the top surface of the lower limiting ring, and a guide groove is provided on the top surface of one side of the device body. The guide groove is adapted to the shape of the notch. The connecting block is movably connected between the guide groove and the notch. The steering ring is rotatably connected between the upper limiting ring and the lower limiting ring. An inner groove is provided on the inner wall of one side of the device body. A second motor is installed in the inner groove. A first gear is provided on the output end of the second motor. The bottom side of the lower limiting ring is connected to the inner groove. The first gear meshes with the half-tooth ring.

[0010] Preferably, a precision lead screw is horizontally installed inside the support frame, and a first motor is provided at one end of the precision lead screw. The movable block is threadedly connected to the outside of the precision lead screw. An arc-shaped plate is fixedly installed at the bottom end of the lower pressure frame.

Spring blocks are provided at both ends of the impact plate. The spring blocks are connected to the fixed frame by a spring. The impact end of the impact cylinder is connected to the rear side of the impact plate.

[0011] Preferably, a first lead screw is vertically mounted on one end of the support frame, and an abutment plate is threaded onto the outer surface of the first lead screw. One end of the rotating shaft body contacts the abutment plate, and a throttle handle is mounted on one end of the first lead screw.

[0012] The beneficial effects of this utility model are:

[0013] This solution uses a contact plate to limit the rotation shaft body, and the movement of the upper limit ring can complete the connection and disconnection between the steering rings. The connection between the half-tooth ring and the first gear can facilitate the control of the rotation of the rotation shaft body to adjust the opening position. The lower pressure frame can press the rotation shaft during the opening process, and the impact cylinder and impact plate can complete the impact of the holes on both sides.

The connecting block is movably connected in the slot 20. The upper limit ring 12 and the lower limit ring 22 are mutually adapted. The upper rotating block and the lower rotating block are rotatably connected between the two to facilitate the adjustment of the position of the rotating shaft body 2.

[0026] Furthermore, a notch 21 is provided on one side of the top surface of the lower limit ring 22, and a guide groove is provided on the top surface of one side of the device body 1. The guide groove is adapted to the shape of the notch 21. The connecting block is movably connected between the guide groove and the notch 21 to facilitate the opening of the upper rotating block and the upper limit ring 12, which is convenient for feeding. The steering ring 15 is rotatably connected between the upper limit ring 12 and the lower limit ring 22. An inner groove 14 is provided on the inner wall of one side of the device body 1. A second motor 16 is installed in the inner groove 14. A first gear 17 is provided on the output end of the second motor 16.

[0027] In this embodiment, a precision lead screw is horizontally installed inside the support frame 5 to facilitate adjustment of the opening position. A first motor 8 is provided at one end of the precision lead screw, and a movable block 10 is threadedly connected to the outside of the precision lead screw. An arc-shaped plate is fixedly installed at the bottom end of the lower pressure frame 11. The bottom surface of the arc-shaped plate is connected to the outer surface of the rotating shaft body 2 and acts to press the rotating shaft body 2 during the opening process to prevent positional displacement. Fixing frames 23 are installed on both sides of the arc-shaped plate. An impact plate 24 is interactively connected inside the fixing frame 23. An impact end 25 is installed at the center of the impact plate 24 to realize the rotation of the shaft. The punching end 25 of the main body 2 is movably connected to the fixed frame 23.

[0028] Working principle: The rotating shaft body 2 is inserted into the device body 1 from one side by an external feeder. After insertion, the first lead screw 7 is rotated to lower the contact plate 6 completely to the bottom. Then, the second cylinder 13 is extended, and the upper limit ring 12 drives the internal steering ring 15 forward until it reaches the designated position. The upper and lower ring blocks are then connected. During the pushing process, the rotating shaft body 2 is first pushed backward until its tail end connects to the contact plate 6. Only then will the upper ring block connect to the outer surface of the rotating shaft body 2. When drilling, the first cylinder 9 is extended, and the lower pressure frame 11 contacts the outer surface of the rotating shaft body 2 to position it. Then, the impact cylinders 18 on both sides are extended, the impact plate 24 is pushed forward, and the impact end 25 is connected to the outer surface of the rotating shaft body 2 to make a hole. After completion, the impact cylinders 18 retract, and the impact plate 24 returns to its position under the action of the spring. Then the first cylinder 9 retracts, the first motor 8 is rotated, the position of the movable block 10 is adjusted, and a hole is made at the next position. After the hole on the top surface is made, the second motor 16 is rotated, and the first gear 17 drives the steering ring 15 to rotate, thereby switching the angle of the rotating shaft body 2. After the switching is completed, the above operation is repeated to continue punching. When all is completed, the equipment is restored to its initial state.
