Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, and in particular to a feeding mechanism for a feeding machine. Background Technology

[0002] In the field of profile (such as strip sheet) cutting and processing, traditional processes typically require manually placing each profile one by one onto a conveyor track, and then sawing it to a fixed length using a saw head to obtain the required size. In existing technology, cutting equipment relies on operators frequently loading individual profiles; that is, the next profile can only be loaded after the previous one has been sawn. This intermittent loading method has significant drawbacks: First, manual feeding is inefficient and limited by the operator's response speed and physical strength, making continuous production difficult. Especially in batch operations, if feeding is not timely, the saw head may be idle and waiting, causing the equipment to stop waiting for material, which seriously restricts the overall feeding efficiency and increases production costs.

[0003] Secondly, manual operation poses safety hazards. When the profiles are heavy or frequently handled, they are prone to work-related injuries. In addition, insufficient precision in manual placement may cause the profiles to deviate in positioning on the conveyor track, affecting the accuracy of the sawing dimensions.

[0004] Therefore, there is an urgent need to develop a feeding device to solve the efficiency bottlenecks and safety hazards caused by manual feeding, and to improve the automation level and production continuity of the unloading equipment. Utility Model Content

[0005] The purpose of this utility model is to provide a feeding mechanism for a feeding machine to solve the problems existing in the prior art. It uses a storage rack to place multiple profiles, uses a loading bracket to transfer the profiles on the storage rack to a guide frame, and then uses the guide frame to guide the conveying direction of the profiles. This can gradually supply the profiles used for processing, reduce the frequency of manual feeding, reduce safety hazards, and improve the automation level and production continuity of the feeding equipment.

[0006] To achieve the above objectives, this utility model provides the following solution: This utility model provides a feeding mechanism for a feeding machine, including a frame, a guide frame, a storage rack, and a loading bracket. The guide frame is installed on the frame and is used to guide the conveying direction when the profiles are fed. The storage rack is installed on the frame and is used to hold multiple profiles, with the profiles arranged parallel to the conveying direction. The loading bracket includes a lifting module and a translation module. The moving end of the lifting module is used to support the profiles below, and the fixed end of the lifting module is connected to the moving end of the translation module. The fixed end of the translation module is installed on the frame, and the moving direction of the moving end of the translation module is perpendicular to the conveying direction.

[0007] In one embodiment, the guide frame includes a bottom roller and side rollers. The bottom roller is horizontally arranged, and the side rollers are vertically arranged. The side rollers are located on the side of the bottom roller away from the storage rack. There are two or more bottom rollers arranged parallel to each other along the conveying direction, and there are two or more side rollers arranged parallel to each other along the conveying direction.

[0008] In one embodiment, the storage rack includes two or more slide assemblies. Each slide assembly includes a rack side baffle, a small loading slide, a slanted loading slide, and a tilting drive device. The rack side baffle is close to the guide frame. The small loading slide is horizontally disposed on the side of the rack side baffle away from the guide frame. The slanted loading slide is hinged to the end of the small loading slide away from the rack side baffle. The tilting drive device is used to drive the slanted loading slide to tilt upward. When the slanted loading slide tilts upward, the profile placed on the slanted loading slide slides down onto the small loading slide.

[0009] In one embodiment, the storage rack further includes a baffle plate and an extension bracket, the baffle plate being connected to the loading inclined slide in the outer slide assembly via the extension bracket, the baffle plate being used to define the position of the profile in the length direction.

[0010] In one embodiment, the lifting module includes a lifting platform and a lifting drive device. The lifting platform is used to support the profile, and the lifting drive device is used to drive the lifting platform to move up and down. The lifting drive device is installed on the moving end of the translation module.

[0011] In one embodiment, the translation module includes a translation connecting plate and a translation drive device. The fixed ends of two or more lifting modules are mounted on the translation connecting plate. The translation drive device is used to drive the translation connecting plate to move in the horizontal direction and is mounted on the frame.

[0012] In one embodiment, the loading bracket further includes an adjustment component for adjusting the initial position of the lifting module so that the moving end of the lifting module can be located at the middle of the profile in the width direction.

[0013] In one embodiment, the adjustment assembly includes a lead screw, a slider, and a push block. The lead screw is rotatably mounted on the frame, the slider is threadedly connected to the lead screw, the slider is connected to the push block, and the push block is used to define the initial position of the translation connecting plate. The lead screw is also connected to a rotation drive device, which is used to drive the lead screw to rotate.

[0014] In one embodiment, the adjustment component further includes a proximity switch disposed on the push block. The proximity switch is linked to the translation drive device. When the translation connecting plate moves away from the guide frame and triggers the proximity switch, the translation drive device stops driving.

[0015] In one embodiment, a material rack protection assembly is also included, the material rack protection assembly comprising a guard plate and a guardrail, the guard plate being located on the side near the guide frame and the guardrail being located on the side at the starting end of the conveying direction.

[0016] The present invention achieves the following technical advantages over the prior art: This invention utilizes a storage rack to hold multiple profiles. A lifting module of a loading bracket lifts the profiles from the storage rack, and a translation module of the loading bracket transfers the lifted profiles to a guide frame. After the lifting module lowers, the profiles are placed on the guide frame. The guide frame guides the profiles' conveying direction, ensuring accuracy. Overall, it can gradually supply the profiles needed for processing.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] The purpose of this utility model is to provide a feeding mechanism for a feeding machine to solve the problems existing in the prior art. It uses a storage rack to place multiple profiles, uses a loading bracket to transfer the profiles on the storage rack to a guide frame, and then uses the guide frame to guide the conveying direction of the profiles. This can gradually supply the profiles used for processing, reduce the frequency of manual feeding, reduce safety hazards, and improve the automation level and production continuity of the feeding equipment.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1-8 As shown, this utility model provides a feeding mechanism for a feeding machine, including a frame 1, a guide frame 2, a storage rack 3, and a loading bracket 4. The frame 1 supports the aforementioned components, ensuring they have a suitable height and stable relative position. The frame 1 includes vertical rods 11 and horizontal beams 12, which are connected to form a frame structure. The guide frame 2 is mounted on the frame 1 and guides the conveying direction of the profile 6 during feeding. It uses rollers or drums to facilitate the movement of the profile 6 and ensures accurate conveying direction, preventing skewing that could affect subsequent processing. The storage rack 3 is mounted on the frame 1 and can hold multiple profiles 6, typically more than two, to allow for batch storage and reduce refill frequency. The profiles 6 are placed parallel to the conveying direction, allowing them to be directly transferred from the storage rack 3 to the guide frame 2 without changing direction, improving the convenience of connecting the storage rack 3 and the guide frame 2. The loading bracket 4 includes a lifting module 41 and a translation module 42. The moving end of the lifting module 41 is used to support the profile 6 below it. The lifting module 41 can raise or lower the position of the profile 6. The fixed end of the lifting module 41 is connected to the moving end of the translation module 42. The moving direction of the moving end of the translation module 42 is perpendicular to the conveying direction. The fixed end of the translation module 42 is installed on the frame 1. The translation module 42 can drive the entire lifting module 41 to move horizontally, thereby moving the profile 6 on the storage rack 3 towards the guide frame 2 and placing the profile 6 on the guide frame 2. The profile 6 located on the guide frame 2 can be directly conveyed.

[0023] The feeding process of this utility model is as follows: Multiple profiles 6 are placed on the storage rack 3. The lifting module 41 of the loading bracket 4 rises below the profile 6 and supports one profile 6. Then, the translation module 42 of the loading bracket 4 moves horizontally toward the guide frame 2. After reaching the guide frame 2, the lifting module 41 drives the profile 6 to descend, so that the profile 6 is placed on the guide frame 2. The profile 6 on the guide frame 2 is transported to the saw head position for processing along the conveying direction. Then, the loading bracket 4 continues to return to the storage rack 3 below the profile 6 and repeats the above actions to feed the next profile 6. When the number of profiles 6 on the storage rack 3 decreases, they are replenished in time.

[0024] This invention utilizes a storage rack 3 to hold multiple profiles 6. The lifting module 41 of the loading bracket 4 lifts the profiles 6 from the storage rack 3, and the translation module 42 of the loading bracket 4 transfers the lifted profiles 6 above the guide frame 2. After the lifting module 41 descends, the profiles 6 are placed on the guide frame 2. The guide frame 2 guides the conveying direction of the profiles 6, ensuring the accuracy of the conveying direction. Overall, it can gradually supply the profiles 6 needed for processing. By replenishing multiple profiles 6 to the storage rack 3 at once, instead of directly conveying the profiles 6 towards the saw head, the frequency of manual loading is reduced, safety hazards are lowered, and the automation level and production continuity of the unloading equipment are improved.

[0025] In one embodiment, combined with Figure 2 As shown, the guide frame 2 includes a bottom roller 21 and side rollers 22. The bottom roller 21 is horizontally arranged and rolled on a roller seat via a support shaft. The roller seat is mounted on a crossbeam 12 of the frame 1, and the crossbeam 12 supports the relative position of the bottom roller 21. The side roller 22 is vertically arranged and rolled on another roller seat via another support shaft. This roller seat is also mounted on the crossbeam 12, and the crossbeam 12 supports the relative position of the side roller 22. The side roller 22 is located on the side of the bottom roller 21 away from the storage rack 3, so that when the profile 6 is placed on the bottom roller 21, the side roller 22 can constrain and limit the lateral position of the profile 6. Two or more bottom rollers 21 are arranged parallel to each other along the conveying direction to stably support the horizontal position of the profile 6 and maintain the parallel and stable conveying of the profile 6. Two or more side rollers 22 are arranged parallel to each other along the conveying direction to limit the lateral position of the profile 6 and maintain the stability and accuracy of the conveying direction of the profile 6.

[0026] In one embodiment, combined with Figure 2 and Figure 3As shown, the storage rack 3 includes two or more sets of slide table assemblies 31. These multiple sets of slide table assemblies 31 are arranged in parallel and at intervals to stably hold multiple profiles 6. Each slide table assembly 31 includes a rack side baffle 311, a small loading slide 312, a loading inclined slide 313, and a tilting drive device 314. The rack side baffle 311 is located near the guide frame 2 and is used to limit the profiles 6 to be loaded, ensuring they are in a defined position for support by the loading bracket 4. The small loading slide 312 is horizontally positioned on the side of the rack side baffle 311 away from the guide frame 2. The small loading slide 312 is used to temporarily store the profiles 6 to be loaded. With the cooperation of the rack side baffle 311, the profiles 6 are positioned on the small loading slide 312, ready for loading. The loading inclined slide 313 is hinged to the end of the loading small slide 312 away from the side baffle 311 of the material rack. When the profile 6 is placed on the loading small slide 312, the loading inclined slide 313 is in a horizontal position so that after the profile 6 on the loading small slide 312 is lifted by the loading bracket 4, the profile 6 on the loading inclined slide 313 will not move toward the loading small slide 312 and interfere with the lifting and horizontal movement of the loading bracket 4. The loading inclined slide 313 is connected to a tilting drive device 314. The tilting drive device 314 can be a telescopic drive structure such as a cylinder, hydraulic cylinder, or electric push rod, or it can be a drive form such as a cam structure. The tilting drive device 314 drives the loading inclined slide 313 to tilt upward. Then, when the loading inclined slide 313 tilts upward, the profile 6 placed on the loading inclined slide 313 slides down onto the loading small slide 312. During the sliding process, the side baffle 311 of the material rack limits the sliding position of the profile 6. The loading small slide 312 and the loading inclined slide 313 can be equipped with smooth plates or rollers to reduce the friction on the profile 6.

[0027] In this utility model, both the small loading slide 312 and the inclined loading slide 313 in the storage rack 3 can hold profiles 6. The small loading slide 312 serves as the loading position, which cooperates with the loading bracket 4 to load the profiles 6. After the loading position is empty, the inclined loading slide 313 is tilted upward, so that the profiles 6 on the inclined loading slide 313 slide down to the small loading slide 312 to wait for loading. Then, the inclined loading slide 313 returns to a horizontal state. When the number of profiles 6 on the inclined loading slide 313 decreases, the profiles 6 can be replenished at any time according to the production situation to ensure the continuity of the processing.

[0028] In one embodiment, combined with Figure 3 and Figure 4As shown, the storage rack 3 also includes a baffle plate 32 and an extension bracket 33. The baffle plate 32 is connected to the extension bracket 33, and the extension bracket 33 may be provided with one or more extension brackets to extend the baffle plate 32 to a suitable position that matches the length of the profile 6. The baffle plate 32 is connected to the loading inclined slide 313 in the outer slide assembly 31 through the extension bracket 33. When the loading inclined slide 313 is tilted, it causes the baffle plate 32 to tilt accordingly, so that the baffle plate 32 always limits the position of the profile 6 in the length direction. Therefore, when the profile 6 on the storage rack 3 is loaded onto the guide frame 2, the consistency and accuracy of the position can be maintained.

[0029] In one embodiment, combined with Figures 3-5 As shown, the lifting module 41 is provided with at least two sets to simultaneously lift different parts of the profile 6 along its length, ensuring the stability of the profile 6 during the lifting process. Each lifting module 41 includes a lifting support plate 411 and a lifting drive device 412. The lifting support plate 411 supports the profile 6, and the lifting drive device 412 drives the lifting support plate 411 to move up and down. That is, the lifting support plate 411 is located below the profile 6. When the lifting drive device 412 rises, it can lift the profile 6 from the loading slide 312 on the storage rack 3. The lifting drive device 412 can be in the form of a cylinder, hydraulic cylinder, electric push rod, or lead screw and nut structure to achieve vertical lifting drive. The fixed end of the lifting drive device 412 is installed on the moving end of the translation module 42 so that the translation module 42 can drive the entire lifting module 41 to move horizontally.

[0030] In one embodiment, combined with Figure 3 and Figure 4 As shown, the translation module 42 includes a translation connecting plate 421 and a translation drive device 422. The fixed ends of two or more lifting modules 41 are mounted on the translation connecting plate 421, and all lifting modules 41 are moved synchronously in the horizontal direction by a single translation connecting plate 421. The translation drive device 422 can adopt a linear drive structure such as a cylinder, hydraulic cylinder, or electric push rod. The fixed end of the translation drive device 422 is mounted on a crossbeam 12 on the frame 1, and the movable end of the translation drive device 422 is used to drive the translation connecting plate 421 to move in the horizontal direction. During the loading of the profile 6, after the lifting module 41 removes the profile 6 from the loading slide 312, the translation module 42 drives the lifting module 41 and the profile 6 to move together towards the guide frame 2 until the profile 6 touches the side roller 22 for positioning, and then the profile 6 is brought to the top of the guide frame 2. After the lifting module 41 is lowered, the profile 6 is placed on the guide frame 2.

[0031] In one embodiment, combined with Figure 3 and Figure 4As shown, the loading bracket 4 also includes an adjustment component 43. The adjustment component 43 is used to adjust the initial position of the lifting module 41, so that the moving end of the lifting module 41 (such as the lifting plate 411) can be located in the middle of the width direction of the profile 6, thereby making it suitable for profiles 6 of different widths. This ensures that stable support and translation of the profile 6 can still be achieved after changing the width model of the profile 6. The adjustment component 43 can be set on the translation connecting plate 421. That is to say, the adjustment component 43 is a displacement adjustment structure perpendicular to the conveying direction. For example, the fixed end of the lifting module 41 is not directly fixed on the translation connecting plate 421, but is slidably set on the translation connecting plate 421. The position of the lifting module 41 on the translation connecting plate 421 can be changed by using the adjustment component 43, thereby realizing the adjustment of the initial position of the lifting module 41.

[0032] In one embodiment, combined with Figure 4 As shown, this utility model provides an adjustment method for the initial position of the lifting module 41 that differs from the aforementioned methods. The adjustment assembly 43 includes a lead screw 431, a slider 432, and a pusher block 433. The lead screw 431 is rotatably mounted on the frame 1, such as on the vertical rod 11 of the frame 1, to provide rotational support for the lead screw 431. The axial direction of the lead screw 431 is perpendicular to the conveying direction of the guide frame 2. The slider 432 is threadedly connected to the lead screw 431 and connected to the pusher block 433. That is, when the lead screw 431 rotates, the slider 432 is restricted from rotating, but can reciprocate along the axial direction of the lead screw 431. The push block 433 is located on the side of the translation connecting plate 421 away from the guide frame 2. By moving the position of the push block 433, the initial position of the translation connecting plate 421 can be limited. That is, the push block 433 limits the maximum displacement of the translation connecting plate 421 away from the guide frame 2, but does not limit the position in the direction towards the guide frame 2. In other words, in this adjustment method, the adjustment component 43 does not move with the translation connecting plate 421 in the translation module 42, but only plays a limiting role. At the same time, the lifting module 41 can also be directly fixedly connected to the translation connecting plate 421, eliminating the need for a sliding connection, reducing the complexity of the structure and simplifying the structure. The lead screw 431 is also connected to a rotation drive device, which is used to drive the lead screw 431 to rotate. The rotation drive device can be electrically controlled by a motor, or it can be manually controlled by a handwheel installed at the end of the lead screw 431.

[0033] In one embodiment, when the translation drive device 422 moves the translation connecting plate 421 away from the guide frame 2, the translation connecting plate 421 needs to stop moving after contacting the push block 433. At this time, manual control or linkage control can be used. In the linkage control, the adjustment component 43 also includes a proximity switch (not shown in the figure). The proximity switch is set on the push block 433. After the translation connecting plate 421 touches the push block 433, it can obtain an electrical signal of the position of the translation connecting plate 421. The proximity switch is linked with the translation drive device 422, that is, the electrical signal of the proximity switch can be transmitted to the translation drive device 422 (or feedback adjustment is performed through the controller). When the translation connecting plate 421 moves away from the guide frame 2 and touches the proximity switch, the translation drive device 422 stops driving. At this time, in the adjusted position, the lifting plate 411 of the lifting module 41 is exactly below the profile 6 on the loading slide 312 and is located in the middle of the width direction of the profile 6.

[0034] In one implementation, such as Figures 1-3 As shown, it also includes a material rack protection component 5. The material rack protection component 5 is mainly used to prevent personnel from approaching the equipment and causing injury, and also to prevent damage to the equipment from collisions with external devices. The material rack protection component 5 includes a guard plate 51 and a guardrail 52. The guard plate 51 is located on the side closest to the guide frame 2, and it largely covers the side of the guide frame 2. This side is a non-operational surface and can be covered. The upper part of the guard plate 51 has a perforated structure to facilitate observation of the equipment's operation. The guardrail 52 is located on the side at the beginning of the conveying direction, which is a personnel operation area. The guardrail 52 has limited obstruction space, providing protection without affecting normal operation.

[0035] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
