Abstract
Description
Technical Field
[0001] This utility model relates to the field of buffer equipment technology, and in particular to a buffer machine for conveyor belts. Background Technology
[0002] In modern production lines, buffer machines serve as crucial devices connecting equipment with varying conveying speeds. Their stability and flexibility directly impact the efficiency and quality of the entire production process. Traditional buffer machine designs often prioritize simple material transfer and stacking functions, neglecting the importance of automatic control over conveying speed.
[0003] In existing technologies, buffer machines typically employ a simple strategy of material accumulation and waiting when faced with two conveying devices at different speeds. While this passive buffering method serves as a material transfer mechanism to some extent, it lacks the ability to actively adjust the conveying speed and cannot precisely control the material flow according to actual needs. When the upstream equipment conveys too quickly while the downstream equipment has limited processing capacity, the buffer zone is prone to accumulating a large amount of material, causing congestion and stagnation in the production line. Conversely, if the upstream equipment conveys too slowly, the downstream equipment may frequently stop due to material shortages, affecting production efficiency.
[0004] Furthermore, existing buffer machines are insufficient in handling emergencies. For example, when upstream processes stop production due to malfunctions or maintenance, traditional buffer machines often cannot adjust in time, causing downstream processes to be paralyzed due to material shortages. This not only increases production line downtime but may also lead to unstable product quality and increased production costs. Therefore, a conveyor belt buffer machine is provided to solve the above-mentioned technical problems. Utility Model Content
[0005] The purpose of this invention is to provide a buffer machine for conveyor belts to address the shortcomings of existing technologies, thereby solving the technical problem that existing buffer machines cannot automatically control the conveying speed.
[0006] To achieve the above objectives, the technical solution of this utility model is as follows:
[0007] A buffer machine for conveyor belts includes a support frame and a lifting frame that is movably disposed inside the support frame. The lifting frame is equipped with a plurality of support modules for carrying material plates and a conveying module for conveying material plates to different support modules. The support modules are arranged in a stacked manner.
[0008] The support frame has a discharge port formed on its side. The discharge port is located on the side of the lifting frame away from the conveying module. The support frame is equipped with a pushing component for pushing the material plates placed on the support module one by one through the discharge port. The pushing component is located above the conveying module and aligned with the discharge port.
[0009] Furthermore, a number of vertically arranged first lead screws are rotatably provided inside the support frame, and a number of connecting seats that are threadedly connected to different first lead screws are installed on the side of the lifting frame; each first lead screw has a synchronous pulley at its bottom end, and a synchronous belt is wound around the synchronous pulley.
[0010] Furthermore, the support module includes a left support part and a right support part at the same height. The left support part and the right support part are respectively installed on the opposite inner sidewalls of the lifting frame. The side of the left support part and the right support part that are close to each other is formed with a material plate bearing groove, and a number of rollers arranged in an array along the length direction are installed on the bottom surface of the bearing groove.
[0011] Furthermore, a guide bevel is formed at the opening of the bearing groove near the conveying module.
[0012] Furthermore, the material pushing component includes a support frame and a slide rod slidably mounted on the support frame. The sliding direction of the slide rod is consistent with the conveying direction of the material plate, and a push rod for contacting the material plate is installed on the end of the slide rod near the discharge port.
[0013] Furthermore, a soft pad is provided on the side of the push rod that contacts the material plate.
[0014] Furthermore, a second lead screw with its axis parallel to the axis of the slide rod is rotatably mounted on the support frame, and a connecting piece threadedly connected to the second lead screw is fixed on the push rod; a servo motor is also mounted on the support frame, and a transmission wheel is provided on the output shaft of the servo motor and the end of the second lead screw near the servo motor, with a transmission belt wound around the transmission wheel.
[0015] Furthermore, the support frame is provided with several mounting parts placed at the edge of the discharge port, and the mounting parts are provided with several brushes for cleaning the material plate passing through the discharge port.
[0016] The beneficial effects of this utility model are as follows: In use, the lifting frame is placed at the lowest point within the support frame, and the end of the conveying module connects to the uppermost support module. The conveying module intermittently conveys the material plate. After a material plate is conveyed to the uppermost support module, the lifting frame is controlled to move upward a specified distance, so that the next layer of support module connects to the end of the conveying module, thereby conveying the next material plate to that support module. This process is repeated sequentially. With the intermittent conveying of the material plate by the conveying module and the intermittent upward movement of the lifting frame, each support module within the lifting frame... Each support module carries a material plate. Then, the lifting frame is controlled to move upward to the highest point within the support frame. At this point, the support module at the bottom is aligned with the pushing component and positioned between the pushing component and the discharge port. The pushing component is operated to push the material plate on the support module out. After passing through the discharge port, the material plate is conveyed to the next mechanism for processing. Through the intermittent operation of the pushing component and the intermittent downward movement of the lifting frame, each material plate on the support module is pushed out one by one. After all the material plates have been pushed out, they can be coordinated with the conveying module again to convey the subsequent material plates to each support module.
[0017] In the process of conveying material plates, this buffer machine is set up to connect two conveying devices with different conveying speeds. After the material plate passes through the buffer machine, it can be conveyed stably, achieving the effect of automatic flow control, thereby reducing the impact on subsequent processes. At the same time, it can also cope with emergencies, such as the unexpected shutdown of upstream processes. The material plates can be temporarily stored through various support modules to ensure the orderly production of subsequent processes, achieving the buffering effect. Attached Figure Description

[0028] The following is a detailed description of a buffer machine for conveyor belts according to the present invention, with reference to the accompanying drawings.
[0029] like Figure 1-3 As shown, an embodiment of the conveyor belt buffer machine of the present invention includes a support frame 1 and a lifting frame 3 that is movably arranged inside the support frame 1. The lifting frame 3 is equipped with a plurality of support modules for carrying material plates. The support modules are arranged in a stacked manner. The support frame 1 is also equipped with a conveying module 12 for conveying the material plates to different support modules. Initially, the lifting frame 3 is positioned at the lowest point within the support frame 1. The end of the conveying module 12 connects to the uppermost support module, and the beginning of the conveying module 12 connects to a conveying device (not shown in the figure) for intermittently supplying material plates. The conveying device intermittently supplies material plates, allowing the conveying module 12 to intermittently convey them. After a material plate is conveyed to the uppermost support module, the lifting frame 3 is controlled to move upwards a specified distance, connecting the next support module to the end of the conveying module 12, thus conveying the next material plate to that support module. This process is repeated sequentially. With the intermittent conveying of material plates by the conveying module 12 and the intermittent upward movement of the lifting frame 3, each support module within the lifting frame 3 carries a material plate. Additionally, the conveying module 12 is existing technology and can be a conveying structure using conveyor wheels and belts, or a double-speed chain or other structure capable of conveying plate-shaped materials; details are omitted here. The material plate can be a circuit board, PCB board, or other plate-shaped material.
[0030] The support frame 1 has a discharge port 14 formed on its side, which is connected to another conveying device (not shown in the figure). The discharge port 14 is located on the side of the lifting frame 3 away from the conveying module 12. The support frame 1 is equipped with a pushing component 13 for pushing the material plates placed on the support module one by one to pass through the discharge port 14. The pushing component 13 is located above the conveying module 12 and aligned with the discharge port 14. Specifically, the conveying speeds of the conveying equipment (not shown in the figure) connected to the initial end of the conveying module 12 and the conveying equipment (not shown in the figure) connected to the discharge port 14 are different. After each support module in the lifting frame 3 is equipped with a material plate, the lifting frame 3 is controlled to move upward to the highest point in the support frame 1. At this time, the support module at the bottom is aligned with the pushing component 13 and positioned between the pushing component 13 and the discharge port 14. The pushing component 13 is operated to push the material plate on the support module. After the material plate passes through the discharge port 14, it is pushed onto the corresponding conveying equipment (not shown in the figure), thereby conveying the material plate to the next mechanism for processing. With the intermittent operation of the pushing component 13 and the intermittent downward movement of the lifting frame 3, each material plate placed on the support module is pushed out one by one. After all the material plates are pushed out, they can be coordinated with the conveying module 12 again to convey the subsequent material plates to each support module. In the process of conveying material plates, this buffer machine is set up to connect two conveying devices with different conveying speeds. After the material plates are buffered by this buffer machine, the flow rate can be controlled, thereby reducing the impact on subsequent processes. At the same time, it can also cope with emergencies, such as the unexpected shutdown of upstream processes. The material plates can be temporarily stored through various support modules to ensure the orderly production of subsequent processes and achieve the buffering effect.
[0031] Furthermore, to control the intermittent upward or downward movement of the lifting frame 3 within the support frame 1, several vertically arranged first lead screws 2 are rotatably installed within the support frame 1, and several connecting seats 4, each threadedly connected to a different first lead screw 2, are installed on the side of the lifting frame 3. By driving the first lead screw 2 to rotate, the lifting frame 3 can be controlled to move freely up and down within the support frame 1. A synchronous pulley 5 is provided at the bottom end of each first lead screw 2, and a synchronous belt 6 is wound around the synchronous pulley 5. When the power source drives one of the first lead screws 2 to rotate, all the first lead screws 2 can rotate synchronously, thereby saving costs and energy consumption.
[0032] like Figure 4-5As shown, the support module includes a left support portion 7 and a right support portion 8 at the same height. The left support portion 7 and the right support portion 8 are respectively installed on opposite inner sidewalls within the lifting frame 3. A material plate bearing groove 9 is formed on the side of the left support portion 7 and the right support portion 8 that is close to each other. Several rollers 10 arranged in an array along the length of the bearing groove 9 are installed on the bottom surface of the bearing groove 9. When one of the support modules is connected to the end of the conveying module 12, the conveying module 12 conveys the material plate, thereby conveying the material plate to the left support portion 7 and the right support portion 8. The bottom edge of the material plate is placed within the bearing groove 9, thus supporting the material plate. Additionally, the rollers 10 are used to contact the bottom surface of the material plate, reducing the friction between the material plate and the bearing groove 9 to facilitate the conveying of the material plate.
[0033] Additionally, a guide bevel 11 is formed at the opening of the bearing groove 9 near the conveying module 12. The guide bevel 11 guides the material plate during the conveying process, so that the material plate can be accurately conveyed to the left support part 7 and the right support part 8.
[0034] like Figure 6-7 As shown, the pushing component 13 includes a support frame 131 and a slide rod 132 slidably disposed on the support frame 131. The sliding direction of the slide rod 132 is consistent with the conveying direction of the material plate. A push rod 133 for contacting the material plate is installed on the end of the slide rod 132 near the discharge port 14. After applying force to the push rod 133, the push rod 133 moves on the support frame 131 in a direction closer to or away from the discharge port 14, thereby pushing out the material plates on the support module one by one. A soft pad 134 is provided on the side of the push rod 133 that contacts the material plate. Under the action of the soft pad 134, damage to the material plate is prevented during the stacking process.
[0035] To control the sliding of the push rod 133 on the support frame 131, a second lead screw 135 with its axis parallel to the axis of the slide rod 132 is rotatably mounted on the support frame 131. A connecting piece 136 threadedly connected to the second lead screw 135 is fixed on the push rod 133. Driving the second lead screw 135 to rotate controls the push rod 133 to move towards or away from the discharge port 14. A servo motor 137 is also mounted on the support frame 131. Both the output shaft of the servo motor 137 and the end of the second lead screw 135 near the servo motor 137 are equipped with transmission wheels 138, and a transmission belt 139 is wound around the transmission wheels 138. Running the servo motor 137 drives the second lead screw 135 to rotate through the transmission wheels 138 and the transmission belt 139.
[0036] like Figure 8As shown, the support frame 1 is provided with several mounting parts 15 placed at the edge of the discharge port 14, and several brushes 16 are provided on the mounting parts 15 for cleaning the material plates passing through the discharge port 14; during the process of the control push rod 133 pushing the material plate on the support module to pass through the discharge port 14, the brushes 16 contact the surface of the material plate, thereby cleaning the material plate and facilitating the subsequent processing of the material plate.
[0037] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.
[0038] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of this utility model. The content of this specification should not be construed as a limitation of this utility model.
