Therefore, they should not be construed as limitations on this utility model.

[0030] Please see Figures 1-5 The present invention relates to a reversing conveying device for solid wood composite flooring substrate, comprising a frame 1, a forward conveying device 2 and a reversing conveying device 3.

[0031] The forward conveying device 2 includes a bottom support beam 201, a forward transmission assembly 202, and roller assemblies 203. Multiple bottom support beams 201 are fixedly mounted on the upper surface of the frame 1, providing stable support for the entire forward conveying structure. Multiple roller assemblies 203 are mounted on the bottom support beams 201. The forward transmission assembly 202 is connected to the roller assemblies 203, driving the roller assemblies 203 to rotate, thereby achieving stable forward conveying of the substrate.

[0032] The bottom support beam 201 is also provided with multiple clearance openings 204 for avoiding the aluminum frame 301a. When the lifting component 301 is working, the clearance openings 204 can prevent the aluminum frame 301a from interfering with the bottom support beam 201, ensuring the normal operation of the equipment. At the same time, it optimizes the overall structural layout, making the device more compact and reasonable.

[0033] The forward drive assembly 202 includes a forward drive motor 202a and a motor mounting base 202b. The forward drive motor 202a is mounted on the lower part of the frame 1 through the motor mounting base 202b, making reasonable use of space. The forward drive motor 202a is connected to one of the connecting rollers 203a through a sprocket and chain connection, transmitting the motor's power to the roller assembly 203 and driving the entire forward conveying device 2 to run.

[0034] Each roller assembly 203 includes a connecting roller 203a and a Flywheel 203b. Multiple Flywheels 203b are evenly distributed on the connecting roller 203a. The Flywheels 203b reduce friction between the substrate and the roller, making substrate transport smoother. The connecting roller 203a is connected to the bottom support beam 201 via a bearing housing, ensuring flexible rotation. Adjacent connecting rollers 203a are connected by a sprocket and chain, achieving synchronous rotation of multiple rollers and ensuring stability of the substrate during forward transport.

[0035] The reversing conveyor 3 includes a lifting assembly 301, multiple belt conveyor assemblies 302, and a reversing transmission assembly 303. The lifting assembly 301 is connected to the frame 1 and the belt conveyor assemblies 302 respectively, and is used to lift the belt conveyor assemblies 302 to a suitable height when reversal is required, so that they can receive the substrate from the forward conveyor 2. The reversing transmission assembly 303 is connected to the belt conveyor assemblies 302 and provides reversing power to the belt conveyor assemblies 302. The conveying direction of the belt conveyor assemblies 302 is designed to be 90 degrees to the conveying direction of the roller assembly 203, ensuring that the substrate can be smoothly conveyed in a 90-degree reversing direction.

[0036] The lifting assembly 301 includes an aluminum frame 301a, a drive cylinder 301b, two first connecting rods 301c, a second connecting rod 301d, a first swing rod 301e, a second swing rod 301f, a third swing rod 301g, and a connecting plate 301h fixedly connected to the aluminum frame 301a. The cylinder body of the drive cylinder 301b is fixedly connected to the frame 1, and its telescopic rod is rotatably connected to the lower end of the first swing rod 301e. When the drive cylinder 301b extends or retracts, it drives the first swing rod 301e to rotate. The middle part of the first rocker arm 301e is connected to the first connecting rod 301c near the end of the drive cylinder 301b via a bearing, and the other end is rotatably connected to one end of the second connecting rod 301d. One end of the second rocker arm 301f is connected to the first connecting rod 301c away from the drive cylinder 301b via a bearing, and the other end is rotatably connected to the end of the second connecting rod 301d away from the drive cylinder 301b. Through this design of the connecting rod rocker arm mechanism, the linear motion of the drive cylinder 301b is converted into the smooth lifting motion of the aluminum frame 301a. There are four third swing arms 301g, and one end of each third swing arm 301g is connected to a bearing by bolts. There are four connecting plates 301h, and the lower end of each connecting plate 301h is provided with a slot 301j that matches the bearing. Each first connecting rod 301c is provided with two third swing arms 301g, and one end of the third swing arm 301g is connected to the first connecting rod 301c by a bearing, and the bearing on the other end is connected to the slot 301j on the corresponding connecting plate 301h. This further enhances the stability and linkage of the structure and ensures that the aluminum frame 301a will not sway or shift during the lifting process.

[0037] Specifically, the lifting assembly 301 also includes linear bearings 301k and guide shafts 301m. Four linear bearings 301k and four guide shafts 301m are respectively located at the four corners of the aluminum frame 301a. The linear bearings 301k are fixedly connected to the frame 1. One end of the guide shaft 301m is connected to the corresponding linear bearing 301k, and the other end is connected to the aluminum frame 301a through a shaft fixing seat. The cooperation of the linear bearings 301k and the guide shafts 301m provides precise guidance for the lifting and lowering of the aluminum frame 301a, further improving the stability and smoothness of the lifting process and avoiding equipment failure and poor material conveying caused by skewness.

[0038] Specifically, the belt conveyor assembly 302 includes two pulleys 302a, a synchronous belt 302b, and a conveyor belt frame 302c. The conveyor belt frame 302c is mounted on the aluminum frame 301a to provide mounting support for the synchronous belt 302b. The two pulleys 302a are respectively mounted at both ends of the conveyor belt frame 302c via bearing seats, and the two pulleys 302a are connected by the synchronous belt 302b. The reversing transmission assembly 303 drives the pulleys 302a to rotate, thereby driving the synchronous belt 302b to run, realizing the reversing conveying of the substrate. The synchronous belt drive has the advantages of accurate transmission ratio, high efficiency, and good stability, and can meet the requirements of high-precision reversing conveying.

[0039] Specifically, the reversing transmission assembly 303 includes a reversing motor 303a and a drive shaft 303b. The reversing motor 303a is fixedly connected to the aluminum frame 301a, and its shaft is connected to the drive shaft 303b through a sprocket and chain connection. The drive shaft 303b is fixedly connected to each pulley 302a on the side closest to the reversing motor 303a, providing it with rotational power. This transmission method has a compact structure and efficient power transmission, which can ensure the stable operation of the belt conveyor assembly 302 and achieve precise reversing actions.

[0040] Working principle:

[0041] I. Forward Conveying Stage

[0042] The forward drive motor 202a is fixed to the lower part of the frame 1 via the motor mounting base 202b. After the motor starts, the power it generates is transmitted to one of the connecting roller shafts 203a via a sprocket and chain connection. Since the two adjacent connecting roller shafts 203a are connected by a sprocket and chain, the power is transmitted synchronously, enabling all connecting roller shafts 203a to rotate together.

[0043] Multiple float rollers 203b, evenly arranged on the connecting roller 203a, come into contact with the solid wood composite flooring substrate. The float rollers 203b have a low coefficient of friction, which can effectively reduce the resistance of the substrate during the conveying process, ensuring that the substrate moves smoothly and steadily along the set positive direction on the roller assembly 203 supported by the bottom support beam 201, thus achieving initial linear conveying.

[0044] II. Reversal Phase

[0045] When it is necessary to change the orientation of the substrate, the control system issues a command, and the drive cylinder 301b starts to work. The cylinder body of the drive cylinder 301b is fixed on the frame 1, and its telescopic rod extends or retracts, driving the lower end of the first swing rod 301e, which is rotatably connected to it, to move.

[0046] The middle part of the first rocker arm 301e is connected to the first connecting rod 301c near the end of the drive cylinder 301b via a bearing, and its rotation causes the first connecting rod 301c to move in tandem. Simultaneously, one end of the second rocker arm 301f is connected to the first connecting rod 301c away from the drive cylinder 301b via a bearing, and the other end is connected to the second connecting rod 301d, forming a stable linkage system. During the rotation of the first rocker arm 301e, the linear motion of the drive cylinder 301b is converted into smooth vertical lifting motion through the hinged connection between the connecting rods and rocker arms.

[0047] The connecting plate 301h, which is fixedly connected to the aluminum frame 301a, is connected to the first connecting rod 301c via a third swing rod 301g. Each first connecting rod 301c is equipped with two third swing rods 301g, one end of which is connected to the first connecting rod 301c via a bearing, and the other end of which is fitted with a slot 301j on the connecting plate 301h, ensuring both stability and flexibility of the connection. Under the action of the connecting rod swing rod mechanism, the aluminum frame 301a rises smoothly in the vertical direction under the guidance and constraint of the linear bearing 301k and the guide shaft 301m. The linear bearing 301k is fixed to the frame 1, and one end of the guide shaft 301m is fitted to it, while the other end is connected to the aluminum frame 301a, ensuring that the aluminum frame 301a does not deviate or sway, and rises precisely to the predetermined height, making the belt conveyor assembly 302 flush with the conveying plane of the forward conveying device 2, ready to receive the substrate.

[0048] The commutator motor 303a is fixed on the aluminum frame 301a. After starting, its shaft transmits power to the drive shaft 303b through a sprocket and chain connection. The drive shaft 303b is fixedly connected to each pulley 302a on the side closest to the commutator motor 303a, driving the pulley 302a to rotate.

[0049] Two pulleys 302a are respectively mounted at both ends of the conveyor belt frame 302c via bearing seats and connected by a synchronous belt 302b. The rotating pulleys 302a drive the synchronous belt 302b. When the substrate being conveyed in the forward direction reaches above the conveyor belt assembly 302, the substrate is driven and its original conveying direction is changed due to the friction of the synchronous belt 302b, achieving a 90-degree reversal. Subsequently, the reversing substrate is conveyed to the next process under the continuous operation of the conveyor belt assembly 302, completing the entire reversing conveying process. Throughout the process, the clearance 204 on the bottom support beam 201 provides ample space for the raised aluminum frame 301a, avoiding interference between the two and ensuring smooth operation of the equipment.
