Description

Technical Field

[0001] This utility model belongs to the field of cardboard box production technology, and in particular relates to a split-type paper feeding pulley for a box gluing machine. Background Technology

[0002] The paper conveyor in a carton gluing machine is a crucial component. Its main function is to smoothly and accurately transport the cardboard to be glued to the processing position of the machine. Through a transmission device consisting of belts, pulleys, and drive shafts, it achieves continuous and stable cardboard feeding, ensuring that the cardboard's position and orientation meet processing requirements before entering the gluing process. This improves the efficiency and quality of carton gluing production and is widely used in various paper box packaging processes, making it an indispensable pre-processing device for automated carton gluing.

[0003] In paper conveyors, the pulleys near the drive end are more prone to wear due to the driving torque from the power source (such as an electric motor). The pulleys in existing paper conveyors generally adopt an integrated structure. When they are worn and need to be replaced, the worn part cannot be replaced separately. The entire pulley must be replaced, which significantly increases the cost of spare parts. Moreover, it is necessary to disassemble the entire shaft system or related components, which is complicated and leads to prolonged equipment downtime, affecting production efficiency. Summary of the Invention

[0004] To address the problems existing in the prior art, this utility model provides a split-type paper feeding pulley for a box gluing machine, which enables rapid and low-cost independent replacement of vulnerable parts, significantly reducing downtime and lowering spare parts costs.

[0005] This utility model is implemented as follows: a split-type paper feeding pulley for a box gluing machine includes a wheel seat set on the side plate of the conveyor frame, a wheel frame body sleeved on the wheel seat, a shaft core arranged axially in the wheel seat and the wheel frame body, and a transmission shaft passing through the shaft core and connected by a key to transmit torque.

[0006] A bearing is provided between the outer surface of the shaft core and the inner surface of the wheel seat. The shaft core is connected to the wheel frame body by a first fastener. Under the drive of the transmission shaft, the shaft core drives the wheel frame body to rotate relative to the wheel seat.

[0007] Furthermore, the wheel frame body is provided with a mounting part along the radial direction. The mounting part divides the inner cavity of the wheel frame body into a fitting cavity and a mounting cavity. The end of the wheel seat is placed in the fitting cavity. The mounting part in the wheel frame body divides the inner cavity into a fitting cavity and a mounting cavity, making the mounting position of the wheel seat and the axle core clearer, the structure more compact, and the space utilization more reasonable. The mounting part is provided with a through hole for the axle core to pass through.

[0008] A mounting flange is provided on the shaft core away from the wheel seat side, positioned within a mounting cavity. The mounting cavity allows for the embedding of a first fastener and provides operating space. The inner end face of the mounting flange is abutted against the mounting portion and has a through-hole. The tight fit between the inner end face of the mounting flange and the mounting portion constitutes axial positioning, ensuring a rigid connection between the shaft core and the wheel frame during rotation and preventing positional displacement due to vibration or load changes. The mounting flange is connected to the wheel frame via the first fastener.

[0009] Furthermore, the wheel seat includes a sleeve portion, which is a tubular structure. A flange portion is provided on the sleeve portion located on the side of the conveyor frame. The flange portion has a second mounting hole, and the flange portion is connected to the conveyor frame side plate via a second fastener. By utilizing the second mounting hole on the flange portion and connecting it to the conveyor frame side plate via the second fastener, a stable installation of the wheel seat is achieved. This design not only improves the connection strength and stability between the wheel seat and the conveyor frame side plate, ensuring good fixation even under long-term operation and high-load working conditions, but also facilitates installation and disassembly, enabling quick assembly and maintenance of the wheel seat.

[0010] Furthermore, a gap is provided between the end face of the wheel frame body facing the wheel seat and the inner end face of the flange for placing the second fastener. This provides ample space for the placement and installation of the second fastener, while avoiding installation difficulties or damage caused by interference between components.

[0011] Furthermore, the shaft core is provided with a shaft clip for fixing the bearing.

[0012] Furthermore, the drive shaft is a splined shaft, and the shaft core is provided with a splined inner hole. The shaft core and the drive shaft are connected by a spline to realize the transmission torque.

[0013] Furthermore, two bearings are provided, spaced apart axially along the shaft core. A limiting part for fixing the bearings is provided in the inner cavity of the wheel seat between the two bearings. This effectively improves the support stability between the shaft core and the wheel seat. The dual-bearing design can distribute the load, reduce the force on individual bearings, thereby extending the bearing's service life; the limiting part further ensures the accurate position and stable fixation of the bearings in the inner cavity of the wheel seat, preventing axial displacement or loosening of the bearings during operation.

[0014] The advantages and technical effects of this utility model are as follows: Due to the adoption of the above technical solution, each component (such as wheel seat, wheel frame body, shaft core, etc.) can be disassembled and replaced independently, realizing the rapid and low-cost independent replacement of vulnerable parts, significantly reducing downtime and spare parts costs. At the same time, this design also improves the flexibility, adaptability, smooth operation and transmission reliability of the equipment.

[0015] When the wheel frame in contact with the belt wears out, becomes damaged, or needs to be adapted to different requirements (such as changing the belt type or adjusting the pulley diameter), it is not necessary to replace the entire wheel seat, shaft, bearings, or even the drive shaft. Only the first fastener needs to be removed to replace the wheel frame individually. This significantly reduces spare parts costs; the replacement operation is also faster, requiring only the removal of the fasteners related to the wheel frame, without disassembling the bearings, drive shaft, or the entire shaft system. This greatly reduces equipment downtime and improves production efficiency. Attached Figure Description

[0023] like Figures 1 to 4As shown, this application provides a split-type paper feeding pulley for a gluing machine, including a wheel seat 1 mounted on the side plate of the conveyor frame, and a wheel frame body 2 sleeved on the wheel seat 1. Specifically, the outer surface of the wheel frame body 2 is a drum-shaped structure with a higher center and lower sides. A shaft core 3 is axially arranged inside the wheel seat 1 and the wheel frame body 2, and a drive shaft passes through the shaft core 3 and is connected by a key to transmit torque. The axes of the wheel seat 1, the wheel frame body 2, and the shaft core 3 are collinear.

[0024] A bearing 4 is provided between the outer surface of the shaft core 3 and the inner surface of the wheel seat 1. The shaft core 3 is connected to the wheel frame body 2 by a first fastener 5. Specifically, the first fastener 5 is a hexagonal bolt. Under the drive of the transmission shaft, the shaft core 3 drives the wheel frame body 2 to rotate relative to the wheel seat 1.

[0025] Furthermore, a mounting part 2-1 is provided radially inside the wheel frame body 2. The mounting part 2-1 divides the inner cavity of the wheel frame body 2 into a fitting cavity 2-2 and a mounting cavity 2-3. The end of the wheel seat 1 is placed in the fitting cavity 2-2. The mounting part 2-1 inside the wheel frame body 2 divides the inner cavity into a fitting cavity 2-2 and a mounting cavity 2-3, making the installation positions of the wheel seat 1 and the shaft core 3 clearer, the structure more compact, and the space utilization more reasonable. The mounting part 2-1 is provided with a through hole 2-4 for the shaft core 3 to pass through.

[0026] A mounting flange 3-1 is provided on the shaft core 3 on the side away from the wheel seat 1, which is placed inside the mounting cavity 2-3. The mounting cavity 2-3 is designed to embed the first fastener 5 and provides operating space. The inner end face of the mounting flange 3-1 is in contact with the mounting part 2-1 and has a through-hole. The inner end face of the mounting flange 3-1 is in close contact with the mounting part 2-1, forming an axial positioning, ensuring that the shaft core 3 and the wheel frame 2 maintain a rigid connection during rotation, and avoiding positional displacement due to vibration or load changes. The mounting flange 3-1 is connected to the wheel frame 2 by the first fastener 5.

[0027] Furthermore, the wheel seat 1 includes a sleeve portion 1-1, which is a tubular structure. A flange portion 1-2 is provided on the sleeve portion 1-1 located on the side of the conveyor frame. The flange portion 1-2 has a second mounting hole. The flange portion 1-2 is connected to the side plate of the conveyor frame via a second fastener. Specifically, the second mounting hole is a countersunk hole, and the second fastener is a countersunk screw. By utilizing the second mounting hole on the flange portion 1-2 and connecting it to the side plate of the conveyor frame via the second fastener, a stable installation of the wheel seat 1 is achieved. This design not only improves the connection strength and stability between the wheel seat 1 and the side plate of the conveyor frame, ensuring good fixation even under long-term operation and high-load working conditions, but also facilitates installation and disassembly, enabling quick assembly and maintenance of the wheel seat 1.

[0028] Furthermore, a gap is provided between the end face of the wheel frame body 2 facing the wheel seat 1 and the inner end face of the flange portion 1-2 for placing the second fastener. This provides ample space for the placement and installation of the second fastener, while avoiding installation difficulties or damage caused by interference between components.

[0029] Furthermore, the shaft core 3 is provided with a shaft clip 6 for fixing the bearing 4.

[0030] Furthermore, the drive shaft is a splined shaft, and the shaft core 3 is provided with a splined inner hole 3-2. The shaft core 3 and the drive shaft are connected by a spline to realize the transmission torque.

[0031] Furthermore, two bearings 4 are provided, spaced apart axially along the shaft core 3. A limiting part 1-3 for fixing the bearings 4 is provided within the inner cavity of the wheel seat 1 located between the two bearings 4. This effectively improves the support stability between the shaft core 3 and the wheel seat 1. The double bearing 4 design can distribute the load, reduce the force on a single bearing 4, thereby extending the service life of the bearing 4; the limiting part 1-3 further ensures the accurate position and stable fixation of the bearing 4 within the inner cavity of the wheel seat 1, preventing axial displacement or loosening of the bearing 4 during operation.

[0032] The advantages and technical effects of this utility model are as follows: Due to the adoption of the above technical solution, each component (such as wheel seat 1, wheel frame 2, shaft core 3, etc.) can be disassembled and replaced independently, realizing the rapid and low-cost independent replacement of vulnerable parts, significantly reducing downtime and reducing spare parts costs. At the same time, this design also improves the flexibility, adaptability, smooth operation and transmission reliability of the equipment.

[0033] When the wheel frame 2, which is in contact with the belt, becomes worn, damaged, or needs to be adapted to different requirements (such as changing the belt type or adjusting the pulley diameter), it is not necessary to replace the entire wheel seat 1, shaft core 3, bearing 4, or even the drive shaft. Only the first fastener 5 needs to be removed to replace the wheel frame 2 individually. This significantly reduces spare parts costs; the replacement operation is also faster, requiring only the removal of the fasteners related to the wheel frame 2, without disassembling the bearing 4, drive shaft, or the entire shaft system. This greatly reduces equipment downtime and improves production efficiency.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
