Description

Technical Field

[0001] This utility model relates to the field of woodworking machinery technology, and in particular to a fixed feeding device. Background Technology

[0002] Edge banding is a crucial step in panel furniture manufacturing, and the stability of the edge banding machine's feeding device directly impacts the quality and efficiency of the edge banding process. Traditional feeding devices typically employ a split sprocket frame structure. While this offers processing convenience, in actual operation, the clearance between multiple components is prone to micro-deformation under long-term dynamic loads. This leads to deterioration in the sprocket assembly's positioning accuracy, causing gear meshing deviations and chain trajectory offsets. The weakest points at the split connections are susceptible to loosening under high-frequency mechanical vibration, requiring frequent maintenance and adjustments and reducing the stability of the chain drive system, directly affecting the straightness and smoothness of the board conveying. Furthermore, the traditional structure has a large transition zone between the highest point of the sprocket and the guide rail, causing the chain to sag in this section. Excessive spacing between the chain block support points leads to flexural vibrations during board conveying, especially at high speeds. Uneven pressure distribution between the board and the chain blocks affects clamping stability. Utility Model Content

[0003] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a fixed feeding device that solves the technical problems of insufficient stability in sheet material conveying caused by vibration offset due to the traditional split design of the sprocket frame, as well as the technical problems of conveying vibration and unstable clamping caused by the large chain suspension span.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: This utility model discloses a fixed feeding device, including a worktable and a driving component. An integrated sprocket bracket is installed at both the feeding and discharging ends of the worktable. A transmission sprocket is rotatably mounted on the integrated sprocket bracket. Two transmission sprockets are located at the same horizontal level and connected by a synchronous chain. Multiple chain blocks arranged at equal intervals are mounted on the synchronous chain. A tension wheel is provided on the side of each of the two transmission sprockets that is close to each other. The tension wheel is rotatably mounted on the integrated sprocket bracket and abuts against the inner side of the synchronous chain. The driving component is fixedly mounted on the integrated sprocket bracket, and its transmission end is connected to the transmission sprockets. An adjustable straight guide rail is also provided between the two transmission sprockets. The straight guide rail is located on the side of the synchronous chain away from the tension wheel and is mounted on the worktable via a connecting support plate. A guide groove adapted to the synchronous chain is provided on the straight guide rail. The end face of the straight guide rail near the feeding end of the worktable is an inclined surface, and the inclined surface is set at an obtuse angle to the worktable.

[0005] As a preferred embodiment, the driving component is disposed at the feed end of the worktable. The driving component includes a servo motor, a motor bracket, a sprocket bearing housing, and a gear shaft. The motor bracket and the sprocket bearing housing are both fixed on the integrated sprocket bracket. The sprocket bearing housing is located between the motor bracket and the integrated sprocket bracket. The servo motor is fixedly mounted on the motor bracket. The transmission end of the servo motor is connected to the gear shaft through the sprocket bearing housing. The transmission sprocket is mounted on the gear shaft and rotates synchronously with the gear shaft.

[0006] As a preferred embodiment, a T-shaped mounting adjustment slide rail is fixedly provided on the side of the integrated sprocket bracket away from the transmission sprocket. A T-shaped mounting groove adapted to the T-shaped mounting adjustment slide rail is provided on the straight guide rail. The T-shaped mounting adjustment slide rail is located above the connecting support plate. A locking T-shaped straight groove is also provided on the side of the straight guide rail near the connecting support plate. A locking bolt adapted to the locking T-shaped straight groove is installed on the connecting support plate.

[0007] As a preferred embodiment, a support bar is installed on one side of the guide groove near the driving component, and a guide rod is installed on the other side. An inclined plate and an inclined cone rod are respectively fixed at the ends of the support bar and the guide rod near the driving component. The inclined plate and the inclined cone rod are both set at an acute angle to the working platform, and the inclined cone rod is inclined towards the direction of the guide groove.

[0008] As a preferred embodiment, the plate placement guide plate is also included. The plate placement guide plate is disposed at the feeding end of the worktable and is mounted on the integrated sprocket bracket by a fixed bracket. The end of the plate placement guide plate near the transmission sprocket is also provided with an avoidance notch corresponding to the chain block. An encapsulation plate is also installed on the side of the integrated sprocket bracket away from the driving component.

[0009] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly enhances the structural stability by adopting an integrated sprocket bracket to reduce mechanical vibration, optimizes the stress on the plate and reduces conveying vibration by cooperating with equally spaced chain blocks and tension wheels, and shortens the transition distance and reduces the suspension of chain blocks by the design of the inclined surface of the straight guide rail, which effectively improves the smoothness of plate conveying and clamping stability.

[0015] Please see Figures 1 to 7 This utility model embodiment provides a fixed feeding device, including a workbench 10 and a drive component 20. The workbench 10 serves as a basic support platform, bearing the operation of the entire feeding device. Both the feeding end and the discharging end of the workbench 10 are equipped with an integrated sprocket bracket 30. The integrated sprocket bracket 30 adopts an integral molding design, which, compared to the traditional split structure, has higher structural strength and stability, effectively reducing the impact of mechanical vibration on feeding accuracy. A transmission sprocket 40 is rotatably mounted on the integrated sprocket bracket 30. The two transmission sprockets 40 are located at the same horizontal level and are connected by a synchronous chain 50. The synchronous chain 50 connects the two transmission sprockets 40. To achieve synchronous power transmission and ensure the straightness and stability of the conveyed sheet material, the synchronous chain 50 is equipped with multiple chain blocks 51 arranged at equal intervals. These blocks evenly bear the sheet material, ensuring balanced force during conveying and reducing flexural vibration. Tensioning wheels 60 are provided on the sides of the two drive sprockets 40 that are close to each other. The tensioning wheels 60 are used to adjust the tension of the synchronous chain 50, preventing a decrease in transmission efficiency and increased vibration caused by slack in the synchronous chain 50. The tensioning wheels 60 are rotatably mounted on the integrated sprocket bracket 30 and abut against the inner side of the synchronous chain 50. Through this abutment, the tension of the synchronous chain 50 is adjusted, maintaining its stable operation. The drive component 20 is fixedly mounted on the integrated sprocket bracket 30. As a power source, the drive component 20 provides driving force to the entire feeding device. The transmission end of the drive component 20 is connected to the transmission sprocket 40. Through this transmission connection, the drive component 20 transmits power to the transmission sprocket 40, thereby driving the synchronous chain 50 to move the chain block 51. An adjustable straight guide rail 70 is also provided between the two transmission sprockets 40. The straight guide rail 70 serves as a guide component for the sheet material conveying. Its adjustable installation allows for easy adjustment of the straight guide rail 70's position according to actual needs, optimizing the sheet material conveying. The straight guide rail 70 is located on the side of the synchronous chain 50 away from the tension wheel 60 and is mounted on the connecting support plate 80. On the workbench 10, the straight guide rail 70 is provided with a guide groove 71 that is compatible with the synchronous chain 50. The design of the guide groove 71 allows the synchronous chain 50 to run smoothly while receiving additional support, ensuring the stability and straightness of the synchronous chain 50 in the process of transporting the plate. The end face of the straight guide rail 70 near the feeding end of the workbench 10 is an inclined surface 72, which is set at an obtuse angle with the workbench 10. This design can significantly shorten the distance between the transmission sprocket 40 and the straight guide rail 70 without avoiding interference between components. That is, it can significantly shorten the transition distance from the highest point of the transmission sprocket 40 to the connection point of the straight guide rail 70, further reducing the suspension of the chain block 51 and ensuring more stable clamping and conveying of the plate.

[0016] In this embodiment, the drive component 20 is located at the feeding end of the workbench 10, facilitating centralized control of the board feeding process and improving operational convenience and efficiency. The drive component 20 includes a servo motor 21, a motor bracket 22, a sprocket bearing seat 23, and a gear shaft 24. The motor bracket 22 and the sprocket bearing seat 23 are both fixed on an integrated sprocket bracket 30, ensuring the stability and rigidity of the entire drive component 20 and reducing vibration and offset. The sprocket bearing seat 23 is located between the motor bracket 22 and the integrated sprocket bracket 30. As an intermediate connecting component, the sprocket bearing seat 23 both supports the gear shaft 24 and ensures the stability of the gear shaft 24. The servo motor 21 is smoothly connected to the drive end of the servo motor 21, which is fixedly mounted on the motor bracket 22. As a power source, the stable installation of the servo motor 21 can ensure the stable output of driving force, improve the reliability and accuracy of the feeding device. The drive end of the servo motor 21 is connected to the gear shaft 24 through the sprocket bearing seat 23, so that the power of the servo motor 21 can be efficiently and accurately transmitted to the gear shaft 24. The transmission sprocket 40 is mounted on the gear shaft 24 and rotates synchronously with the gear shaft 24. The synchronous rotation of the transmission sprocket 40 and the gear shaft 24 ensures the stable operation of the synchronous chain 50, thereby realizing the smooth feeding of the plate.

[0017] Furthermore, a T-shaped mounting and adjusting slide rail 31 is fixed on the side of the integrated sprocket bracket 30 away from the transmission sprocket 40. The design of the T-shaped mounting and adjusting slide rail 31 facilitates the quick installation and position adjustment of the straight guide rail 70, improving the flexibility and maintainability of the device. The straight guide rail 70 has a T-shaped mounting groove adapted to the T-shaped mounting and adjusting slide rail 31. The cooperation between the T-shaped mounting groove and the T-shaped mounting and adjusting slide rail 31 ensures the stability and accuracy of the straight guide rail 70 installation, reducing installation errors. The T-shaped mounting and adjusting slide rail 31 is located above the connecting support plate 80. The layout makes the installation position of the straight guide rail 70 more reasonable, facilitating subsequent adjustments and maintenance. A locking T-shaped straight groove 73 is also provided on the side of the straight guide rail 70 near the connecting support plate 80. The locking T-shaped straight groove 73 provides a structural basis for locking the straight guide rail 70, ensuring the stability of the straight guide rail 70 after adjustment. The connecting support plate 80 is equipped with a locking bolt that matches the locking T-shaped straight groove 73. Through the cooperation of the locking bolt and the locking T-shaped straight groove 73, the straight guide rail 70 can be easily and quickly fixed in the required position to prevent displacement during use.

[0018] A support bar 74 is installed on one side of the guide groove 71 near the drive component 20, and a guide rod 75 is installed on the other side. The support bar 74 enhances the support for one side of the chain block 51, reducing vibration and wear during operation. The guide rod 75 ensures that the sheet material can enter the feeding device smoothly and accurately. Specifically, an inclined plate 741 and an inclined cone rod 751 are respectively fixed at the ends of the support bar 74 and the guide rod 75 near the drive component 20. Both the inclined plate 741 and the inclined cone rod 751 are set at acute angles with the working platform, making the inclined plate 741 and the inclined cone rod 751 more gentle, which is conducive to the smooth transition of the sheet material. In addition, the inclined cone rod 751 is inclined towards the direction of the guide groove 71, providing a lateral guiding stress to ensure that the sheet material is correctly guided during feeding, further improving the stability and efficiency of feeding.

[0019] Furthermore, the fixed feeding device also includes a sheet material placement guide plate 90. The sheet material placement guide plate 90 serves as the initial support platform for the sheet material entering the feeding device, playing a crucial role in the stable placement and smooth introduction of the sheet material. The sheet material placement guide plate 90 is located at the feeding end of the workbench 10 and is mounted on the integrated sprocket bracket 30 via a fixed bracket 91, ensuring the stability and firmness of the sheet material placement guide plate 90 and preventing shaking during sheet material placement and introduction. The end of the sheet material placement guide plate 90 near the transmission sprocket 40 also has an avoidance notch 92 corresponding to the chain block 51, allowing the chain block 51 to pass smoothly during operation and avoiding interference between the chain block 51 and the sheet material placement guide plate 90, ensuring smooth sheet material feeding. An encapsulation plate 32 is also installed on the side of the integrated sprocket bracket 30 away from the drive component 20. The installation of the encapsulation plate 32 not only protects the internal components of the device, preventing dust and debris from entering and affecting the normal operation of the device, but also makes the entire feeding device look cleaner and more aesthetically pleasing.

[0020] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
