Description

Technical Field

[0001] This invention relates to the field of equipment tooling, and more particularly to a hinged flap mechanism. Background Technology

[0002] In factory production processes, it is common to encounter tasks that require folding or flipping workpieces, such as folding and unfolding fabric workpieces like disposable underwear. Currently, fabric folding is typically done manually. To improve work efficiency, automatic folding mechanisms have also emerged.

[0003] Existing automatic folding mechanisms typically use a motor or rotary cylinder to directly drive the hinge shaft, which in turn rotates the flap fixed to the hinge shaft. However, because the hinge shaft is located on one side of the flap, the rotational lever arm of the flap is relatively long during rotation. Therefore, a high-power motor or rotary cylinder is required as the drive source, resulting in a large and bulky drive source. Furthermore, the hinge shaft located on one side of the flap requires a rotation support mechanism, which is complex and difficult to manufacture and install. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a hinged flap mechanism that is simple in structure, occupies little space and consumes little energy.

[0005] This invention is achieved through the following technical solution: A hinged flip-plate mechanism is provided on a workpiece conveying system. The workpiece conveying system includes a frame and a conveying channel mounted on the frame. The conveying channel includes a conveyor belt and mounting side plates located on the left and right sides of the conveyor belt. The hinged flip-plate mechanism includes two sets of hinged flip-plate assemblies arranged opposite each other on the left and right sides. The two sets of hinged flip-plate assemblies are respectively located on the outer sides of the two mounting side plates. Each set of hinged flip-plate assemblies includes a flip plate, a linkage mechanism, and a telescopic actuator. The bottom end of the flip plate is hinged to the top of the mounting side plate by a mounting hinge. The hinge axis of the mounting hinge is parallel to the conveying direction of the conveyor belt. The telescopic actuator is mounted on the frame and located on the lower outer side of the mounting side plate. The linkage mechanism includes a hinged connecting rod and a rocker arm. The other end of the connecting rod is fixedly connected to the middle section of the outer side of the flip plate. The other end of the rocker arm is hinged to the telescopic end of the telescopic actuator extending upward. The telescopic actuator extends vertically, and under the drive of the linkage mechanism, the flip plate flips around the hinge axis of the mounting hinge.

[0006] As a preferred embodiment of the aforementioned hinged flap mechanism, the connecting rod and the rocker arm are hinged together by a first hinge shaft, and the rocker arm and the telescopic end of the telescopic actuator are hinged together by a second hinge shaft. Both the first and second hinge shafts are parallel to the conveying direction of the conveyor belt.

[0007] As a preferred embodiment of the aforementioned hinged flap mechanism, the telescopic actuator is mounted on the frame via an L-shaped mounting plate. The upper part of the vertical section of the L-shaped mounting plate has a waist-shaped hole, the length of which extends perpendicularly to the conveying direction of the conveyor belt. The L-shaped mounting plate is mounted on the frame by passing bolts through the waist-shaped hole and tightening them. The telescopic actuator is mounted on the horizontal section of the L-shaped mounting plate. The frame has clearance holes for the telescopic end of the actuator to extend upwards.

[0008] As a preferred embodiment of the aforementioned hinged flap mechanism, a mounting pad is fixed to the middle section of the outer side of the flap, and a lug is provided on the outer side of the mounting pad. The lug of the mounting pad and the connecting rod are fixedly connected by screws.

[0009] As a preferred embodiment of the aforementioned hinged flip-plate mechanism, the top of the mounting side plate is lower than the conveying surface of the conveyor belt.

[0010] As a preferred embodiment of the aforementioned hinged flap mechanism, the telescopic actuator is a cylinder.

[0011] The present invention has the following advantages over the prior art: The present invention provides a hinged flip-plate mechanism, wherein one end of the flip-plate is hinged to the top of the mounting side plate by a mounting hinge, and the middle part of the flip-plate is driven by a drive transmission structure formed by a telescopic actuator and a linkage mechanism, so that the flip-plate automatically flips around the hinge axis of the mounting hinge, thereby improving the working efficiency of flip-plate folding; moreover, this form has a simple structure, occupies little space, is easy to process and install, and only requires a small driving force to realize the automatic flipping action of the flip-plate, effectively saving energy consumption.

Detailed Implementation

[0015] The embodiments of the present invention are described in detail below. These embodiments are implemented based on the technical solution of the present invention, and provide detailed implementation methods and specific operation processes. However, the scope of protection of the present invention is not limited to the following embodiments.

[0016] See Figure 1 and Figure 2This embodiment discloses a hinged flip-plate mechanism, which is installed on a workpiece conveying system. The workpiece conveying system includes a frame 1 and a conveying channel installed on the frame 1. The conveying channel includes a conveyor belt 2 and mounting side plates 3 located on the left and right sides of the conveyor belt 2. The conveying direction of the conveyor belt 2 is the front-to-back direction, and the top of the mounting side plate 3 is lower than the conveying surface of the conveyor belt 2.

[0017] The hinged flap mechanism includes two sets of hinged flap assemblies arranged opposite each other on the left and right sides. The two sets of hinged flap assemblies are respectively located on the outer sides of the two mounting side plates 3. Only one side of the hinged flap assembly is shown in the figure. Each set of hinged flap assemblies includes a flap 4, a linkage mechanism 5, and a telescopic actuator 6. The bottom end of the flap 4 is hinged to the top of the mounting side plate 3 by a mounting hinge 7. The mounting hinge 7 can be a hinge. The hinge axis of the mounting hinge 7 is parallel to the conveying direction of the conveyor belt 2. The telescopic actuator 6 is mounted on the frame 1 and located on the lower outer side of the mounting side plate 3. The linkage mechanism 5 includes a hinged connecting rod 8 and a rocker arm 9. The other end of the connecting rod 8 is fixedly connected to the middle section of the outer side of the flap 4. A mounting pad 10 is fixed to the middle section of the outer side of the flap 4. A lug is provided on the outer side of the mounting pad 10. The lug of the mounting pad 10 is fixedly connected to the connecting rod 8 by screws. The other end of the rocker arm 9 is hinged to the telescopic end 11 of the telescopic actuator 6 extending upward. The telescopic end 11 of the telescopic actuator 6 extends vertically, and under the drive of the linkage mechanism 5, the flip plate 4 is driven to rotate around the hinge axis on which the hinge 7 is installed.

[0018] The connecting rod 8 and the rocker arm 9 are hinged together by the first hinge shaft 12, and the rocker arm 9 is hinged together with the telescopic end 11 of the telescopic actuator 6 by the second hinge shaft 13. Both the first hinge shaft 12 and the second hinge shaft 13 are parallel to the conveying direction of the conveyor belt 2.

[0019] The telescopic actuator 6 is a cylinder. It is mounted on the frame 1 via an L-shaped mounting plate 14. The upper part of the vertical section of the L-shaped mounting plate 14 has a waist-shaped hole 15. The length of the waist-shaped hole 15 extends perpendicularly to the conveying direction of the conveyor belt 2. Bolts are passed through the waist-shaped hole 15 and tightened onto the frame 1, thus installing the L-shaped mounting plate 14 onto the frame 1. The telescopic actuator 6 is mounted on the horizontal section of the L-shaped mounting plate 14. The frame 1 has a clearance hole 16 for the telescopic end 11 of the telescopic actuator 6 to extend upwards. The waist-shaped hole 15 allows for fine-tuning of the installation height of the telescopic actuator 6, thereby fine-tuning the flip angle of the flap 4.

[0020] In the initial state, the telescopic ends 11 of the telescopic actuators 6 of the two sets of hinged flap assemblies are both in the downward retracted state. The flaps 4 are pulled down by the rocker arm 9 and the connecting rod 8, so that both flaps 4 are in the horizontal outward flipped state, so as to receive the fabric workpiece together with the conveyor belt 2.

[0021] When needed, the telescopic ends 11 of the telescopic actuators 6 of both sets of hinged flap assemblies extend upwards, pushing the upper rocker arm 9 upwards, thereby pushing the connecting rod 8. Under the thrust of the rocker arm 9 and the connecting rod 8, the flap 4 flips upwards around the hinge axis of the mounting hinge 7, completing the folding of both sides of the fabric workpiece. After the folding process is completed, the telescopic ends 11 of the two telescopic actuators 6 retract, and the flap 4 is pulled down to the initial horizontal state through the rocker arm 9 and the connecting rod 8.

[0022] The entire process is fully automated and requires no human intervention, making it highly efficient and convenient.

[0023] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
