Driven synchronous pulley 114 engages with drive synchronous pulley 105, and transmits power via synchronous belt 115, driving the material-stopping beam to move. Drive motor 118 is positioned in the middle of movable pressure table 117. Drive shaft 120 of movable pressure table 117 passes through drive motor 118. Commutator 121 is connected to both sides of drive shaft 120 of movable pressure table 117. Gear 123 is installed at both ends of commutator 121. Rack 122 is positioned on the side of the column. Balance cylinder 119 is fixed at the top of frame 101 of the frame assembly machine, and its head is fixed on commutator 121. Drive motor 118 provides power, and through the transmission of drive shaft 120, commutator 121, gear 123, and rack 122, movable pressure table 117 moves up and down, pressing the bathroom furniture components at the frame assembly position to ensure the components remain stable during the frame assembly process. The balance cylinder 119 is used to balance the weight of the movable pressure table 117, reduce the load on the drive motor 118, and ensure the smoothness of the movement of the movable pressure table 117.

[0027] Reference Figure 1 , Figure 2 and Figure 4The conveyor belt assembly 102 includes: a belt frame 206 as the main body, and side push racks 207 fixed on both sides of the long side of the belt frame 206, serving as the main support structure of the conveyor belt assembly 102. These racks provide mounting bases for other components such as the drive wheel 202, driven wheel 209, transmission track 201, reducer 204, and side push racks 207, ensuring that each component maintains a stable relative position during operation and guaranteeing the normal operation of the entire conveying system.

The side push assembly 103 is also present.

[0028] The side-push assembly 103 includes: a side-push column 313 as the main body, serving as the main support structure of the side-push assembly 103, providing an installation base for other components such as the second transmission bearing 304, the second transmission shaft 301, the third guide rail slider 307, the lower push beam 308, and the middle push beam 309, ensuring that the relative positions of each component are fixed during operation; the second transmission bearing 304 is installed on both sides inside the side-push column 313; the second transmission shaft 301 passes through the second transmission bearing 304 and is installed on both sides inside the side-push column 313, providing support for the rotation of the second transmission shaft 301, reducing the frictional resistance between the second transmission shaft 301 and the side-push column 313 when the second transmission shaft 301 rotates, ensuring that the second transmission shaft 301 can rotate smoothly and stably, thereby ensuring the efficient operation of the entire transmission system, enabling the side-push assembly 103 to perform side-push operations; and the second reducer 303 is fixed on the second transmission shaft 301, serving as a key for power transmission. The key component rotates under the drive of motor 302 and reducer 303, transmitting power to drive synchronous pulley 305, which in turn drives driven synchronous pulley 312 to rotate via synchronous belt 306. Motor 302 is fixed on reducer 303 and connected between motor 302 and transmission shaft 301. Similar to reducer 204, its main function is to reduce the high speed of motor 302 output while increasing the output torque. Drive synchronous pulley 305 is fixed at both ends of transmission shaft 301 and rotates synchronously under the drive of transmission shaft 301. Power is transmitted to driven synchronous pulley 312 via synchronous belt 306, realizing the horizontal movement of the lower push beam 308 and the middle push beam 309. It is the key power transmission component in the transmission system of side push assembly 103. Guide rail slider 307 is fixed on both sides in front of side push column 313.

[0029] The lower push beam 308 is fixed to the guide rail slider 307, the middle push beam 309 is fixed to the guide rail slider 307, the brake cylinder 310 is fixed to the inner rear of the middle push beam 309, the tensioning blocks 311 are fixed to the upper end of the side push column 313, the driven synchronous pulley 312 is fixed between the two tensioning blocks 311, the synchronous belt 306 connects the driving synchronous pulley 305 and the driven synchronous pulley 312, the two commutators 317 are respectively placed below the rear side of the side push column 313, and the horizontal drive shaft 316 is connected to the two commutators 317 with a reduction gear installed in the middle. The servo motor 315 is installed at the tail end of the reducer 314. The bearing 320 is placed on the top of the side push column 313. The lower end of the vertical drive shaft 319 passes through the reducer 314 and the upper end passes through the bearing 320. The vertical drive shaft 319 is fixed with gear 2 318 at the top and bottom respectively. It is fixed on the front sides of the side push column 313 to provide guidance for the horizontal reciprocating motion of the lower push beam 308 and the middle push beam 309, ensuring that the lower push beam 308 and the middle push beam 309 can move along the predetermined straight trajectory and push the bathroom furniture components to the frame position.

[0030] Working Principle: The bathroom furniture assembly conveyor 001 delivers the parts to be assembled to the lower right of the frame assembly 005. The operation control box 002 adjusts various parameters of the equipment to ensure operation. In the frame assembly 005, the frame machine frame 101 supports each part. The conveyor belt assembly 102 transports the parts to the designated position, and the side push assembly 103 guides the parts to the frame position via the guide rail slider 116. The material stop beam drive motor 106 drives the material stop beam to move up and down to position the parts via the rotating shaft 108 and the drive synchronous pulley 105. The drive motor 118 provides power, which is transmitted through the movable pressure table 117 and the transmission shaft 120, etc., so that the movable pressure table 117 presses the parts up and down. The balance cylinder 119 balances the weight. Finally, the discharge conveyor 006 transports the assembled finished product to the subsequent process. All components work together to ensure the efficient, safe and stable operation of the frame assembly process.

[0031] When the conveyor belt assembly 102 is working, the motor 205 starts, and the power is transmitted to the drive wheel 202 at the front end of the belt frame 206 via the reducer 204. The drive wheel 202 drives the external transmission track 201 to rotate, conveying the bathroom furniture components. The bearing 203 ensures the smooth rotation of the drive wheel 202. The rear tensioning block 208 cooperates with the driven wheel 209 to maintain the tension of the transmission track 201 and the circular transmission. The side push rack 207 can assist in the fine-tuning and positioning of the components. In the side push assembly 103, the motor 302 drives the transmission shaft 301 via the reducer 303, and the transmission bearing 304 reduces rotational friction. The transmission shaft 301 drives the drive synchronous pulley 305, which in turn drives the driven synchronous pulley 312 via the synchronous belt 306, realizing the horizontal movement of the lower push beam 308 and the middle push beam 309. The guide rail slider 307 guides, the brake cylinder 310 assists in positioning, and the servo motor 315 adjusts the height of the component through multi-stage transmission, pushing the component to the assembly position.
