Description

Technical Field

[0001] This utility model relates to the field of pipe cutting technology, and in particular to a feeding device and cutting equipment. Background Technology

[0002] Existing pipe cutting equipment commonly employs a single-hopper feeding mode in automated production processes, where pipes are sequentially fed to the cutting station from a single storage hopper. However, this mode has significant drawbacks in practical applications: when the pipes in the hopper are depleted, the equipment must be paused for manual replenishment or while waiting for the hopper to be reloaded, forcing a production interruption. Especially in continuous, high-frequency processing scenarios, frequent downtime for replenishment not only significantly increases non-productive time but also drastically reduces the overall equipment utilization rate. Furthermore, manual replenishment requires repeated start-ups and shutdowns, disrupting the processing rhythm and hindering unmanned continuous production. For pipe processing companies, this issue directly impacts order delivery cycles and equipment capacity, particularly when facing large-volume, multi-batch orders; the traditional single-hopper feeding mode has become a key bottleneck restricting the improvement of automation levels. Although some solutions attempt to extend single-operation time by increasing hopper capacity, limitations in equipment space layout and pipe stacking stability limit hopper expansion, failing to fundamentally solve the supply interruption problem. Therefore, we provide a feeding device and cutting equipment to address these issues. Utility Model Content

[0020] This application also provides a cutting device, which includes the feeding device described in any of the above claims.

[0021] This utility model has the following advantages:

[0022] 1. This utility model features a dual-hopper structure, consisting of a first limiting frame and a barrier forming a first hopper, and a second limiting frame and a barrier forming a second hopper. A lifting drive device alternately lifts the pipes within the two hoppers. A guiding component forms a guiding surface on the top of the first hopper, and a pushing component enables continuous alternating material supply from both hoppers. This effectively solves the problem of refilling materials during single-hopper material supply shutdowns, eliminating the need for the cutting equipment to stop and wait when switching hoppers. The coordinated action of the first and second support plates ensures continuous pipe delivery, significantly improving equipment uptime and production efficiency, and achieving unmanned continuous production operations.

[0023] 2. This utility model sets the barrier component as a double-partition structure consisting of a first partition and a second partition arranged at intervals. This not only forms a stable accommodating space on the machine platform to integrate the lifting drive device, but also effectively separates the first hopper and the second hopper through the interval layout of the first partition and the second partition. At the same time, it reduces the overall weight of the barrier component and optimizes the load distribution of the machine platform.

[0024] 3. This utility model achieves precise guiding and lifting of the lifting plate through the cooperation of the guide column and the first lead screw. Combined with the rotary drive component to drive the first lead screw to rotate to adjust the lifting height, it ensures that the lifting process is stable and controllable. The linkage design of the first rotating component and the first support plate realizes the function of alternating lifting of the two material bins. The rotating support plate can quickly switch to the bottom of the first or second material bin. With the top plate sealing the top of the accommodating space, a continuous conveying plane is formed, which not only ensures the stability of the pipe lifting path, but also avoids the pipe slipping or deviating. At the same time, the fixed connection between the guide column and the top plate enhances the structural strength of the lifting drive device. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] like Figure 1 — Figure 8 The example shown.

[0037] A feeding device includes a machine base 100, a barrier 200, a limiting component, a lifting drive device 400, a guide component 500, and a pushing component 600.

[0038] In some specific embodiments, two support frames 110 are fixedly installed on the machine base 100, and an installation space is defined between the two support frames 110. A barrier 200 is fixedly disposed on the upper surface of the machine base 100 and has a receiving space. The limiting component includes a first limiting frame 310 and a second limiting frame 320 disposed on the machine base 100. A first hopper is defined between the first limiting frame 310 and the barrier 200, and a second hopper is defined between the second limiting frame 320 and the barrier 200. A lifting drive device 400 is installed in the receiving space and is used to lift the workpieces in the first and second hoppers. A guide component 500 is fixedly installed on the first limiting frame 310 and is used to be mounted on the top space of the first hopper to form a guide surface. A pushing component 600 is fixedly installed on the second limiting frame 320 and is used to push the workpieces from the first and second hoppers.

[0039] In this embodiment, the workpieces in the first hopper and the deferred hopper are pipes, bars, etc., and pipes will be used as an example of workpieces in the following description.

[0040] See Figure 1 , Figure 2 as well as Figure 3As shown, in the initial state, the pipes are stacked sequentially in the second and first hoppers, and supported by a bracket formed by two support frames 110. When it is necessary to load the product, for example, when it is necessary to load the pipes in the second hopper, the guide component 500 first forms a guide surface on the top of the first hopper, so that the pipes from the second hopper can pass through the top of the first hopper and enter the cutting equipment to realize loading. Specifically, the lifting drive device 400 first lifts the pipes in the second hopper upward. When the top pipe is in the pushing path of the push component 600, the push component 600 pushes the top pipe through the top of the first hopper and finally enters the cutting equipment, thus completing the loading of the cutting equipment. When it is necessary to load other pipes in the second hopper, the above steps can be repeated.

[0041] After the pipes in the second hopper are fully loaded, the pipes in the first hopper are then loaded. This means that while loading the first hopper, new pipes can be added to the second hopper, allowing for continuous loading of the cutting equipment without stopping the machine. Specifically, when loading the first hopper, the guide assembly 500 first releases the guide surface at the top of the first hopper, thus unsealing the top. Next, the lifting drive device 400 lifts the pipes in the first hopper upwards. When the topmost pipe is lifted into the pushing path of the pusher assembly 600, the pusher assembly 600 pushes the topmost pipe in the first hopper towards the cutting equipment, thus loading the pipes in the first hopper. This process is repeated until all the pipes in the first hopper are loaded. After the first hopper is fully loaded, new pipes are available in the second hopper, allowing for continuous loading without stopping the cutting equipment.

[0042] In some specific embodiments, the barrier 200 includes a first partition 210 and a second partition 220 fixedly installed on the upper surface of the machine base 100. The first partition 210 and the second partition 220 are spaced apart and define an accommodating space.

[0043] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 4As shown, in this embodiment, in order to form a first and second hopper for accommodating pipes, a barrier 200 is disposed between the first limiting frame 310 and the second limiting frame 320. Furthermore, to accommodate the lifting drive device 400, the barrier 200 is spaced apart by the first partition 210 and the second partition 220 to form an accommodating space for the installation of the lifting drive device 400. It should be noted that, to facilitate the upward transfer of pipes from the first and second hoppers by the lifting drive device 400, the left and right sides of the accommodating space are not closed, thus allowing the lifting drive device 400 to pass through. Further, to allow pipes from the second hopper to pass smoothly through the top area of ​​the accommodating space, the top area of ​​the accommodating space is closed by the top plate 470 of the lifting drive device 400, thereby forming a plane for pipes from the first hopper to pass through.

[0044] In some specific embodiments, the lifting drive device 400 includes at least one guide post 410 fixedly installed on the machine base 100, a lifting plate 420 slidably installed on the guide post 410, a first lead screw 430 rotatably installed on the machine base 100, the first lead screw 430 being connected to the lifting plate 420 in a transmission manner, a rotary drive member 440 for driving the first lead screw 430 to rotate fixedly installed on the machine base 100, a first rotating member 450 provided at both ends of the lifting plate 420, a first support plate 460 provided at the rotating end of the first rotating member 450, and a top plate 470 fixedly connected to the barrier member 200 at the top of the guide post 410, the top plate 470 being used to close the top of the receiving space in the second partition 220.

[0045] Please see Figure 4As shown, when it is necessary to lift and load pipes, for example, when it is necessary to lift and load pipes in the second hopper, firstly, the first lead screw 430 is rotated by the rotary drive 440, thereby lowering the lifting plate 420 below the support surface formed by the two support frames 110. Next, the first rotating parts 450 on both sides are activated to rotate the first support plate 460 at its position, so that the first support plate 460 is located below the bottom pipe in the second hopper. Then, the rotary drive 440 drives the first lead screw 430 to rotate again, thereby lifting the lifting plate 420 upward. During the upward lifting process of the lifting plate 420, the first support plate 460 will contact the bottom pipe in the second hopper and drive it to move upward, thereby lifting the pipes in the second hopper upward until the top pipe is lifted to the push path position of the push component 600 to wait to be pushed. Furthermore, after all the pipes in the second hopper have been pushed to the top and the loading is completed, the lifting plate 420 is moved to the bottom of the support surface of the support frame 110. At this time, the first rotating component 450 can be activated again to drive the first support plate 460 to rotate, and rotate the first support plate 460 to the bottom of the pipes in the first hopper. With the cooperation of the rotating drive component 440 and the first lead screw 430, the lifting plate 420 moves upward, and the first support plate 460 supports and lifts the pipes in the first hopper, thereby lifting the pipes in the first hopper in sequence. The above operation is repeated to load the pipes in the second hopper and the first hopper.

[0046] Please continue reading. Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, in order to allow the pipe from the first hopper to pass smoothly through the top of the barrier 200, the top plate 470 is connected to the inner side of the top of the first partition 210 and the second partition 220, thereby closing the inner top of the accommodating space to form a plane for pipe movement, thus facilitating the pushing and feeding of the pipe.

[0047] In this embodiment, the rotary drive component 440 is a motor and the first rotary component 450 is a rotary cylinder.

[0048] In some specific embodiments, the guide assembly 500 includes a second rotating member 510 fixedly mounted on the first limiting frame 310, and a second support plate 520 is fixedly mounted on the rotating end of the second rotating member 510.

[0049] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 5As shown, the pipes from the second hopper need to pass over the top of the first hopper when being fed. Since the top of the first hopper is not closed, in order to prevent the pipes from the second hopper from falling into the first hopper when passing over the top of the first hopper, the second rotating component 510 needs to drive the second support plate 520 to rotate, so that the second support plate 520 rotates to the top area of ​​the first hopper, thereby closing the top of the first hopper. When feeding the pipes from the second hopper, the pipes will pass through the plane formed by the top plate 470 and the second support plate 520 in sequence. The pipes will be pushed through the top plate 470 and the second support plate 520 until they are pushed to the cutting equipment to complete the feeding.

[0050] In this embodiment, the second rotating component 510 is a rotary cylinder.

[0051] In some specific embodiments, a groove 471 is provided on the upper surface of the top plate 470.

[0052] Please see Figure 1 , Figure 2 , Figure 4 as well as Figure 5 As shown, in order to reduce the load of the second support plate 520 on the second rotating member 510, after the second rotating member 510 drives the second support plate 520 to rotate, the end of the second support plate 520 extends into the groove 471, and at this time the upper surface of the top plate 470 is flush with the upper surface of the second support plate 520. The top plate 470 supports the second support plate 520, thereby reducing the load of the second support plate 520 on the second rotating member 510. That is, the second rotating member 510 only needs to exert force on the rotation of the second support plate 520, and does not need to provide force to support the pipe passing through the second support plate 520, thus improving the service life of the second rotating member 510.

[0053] In some specific embodiments, the pusher assembly 600 includes a connecting seat 610 fixedly installed on the first limiting frame 310, a linear drive 620 fixedly installed on the connecting seat 610, and a push plate 630 installed on the telescopic end of the linear drive 620.

[0054] Please see Figure 6As shown, when it is necessary to push the pipe from the second hopper, the second support plate 520 is first placed in the groove 471, and then the push plate 630 is moved by the linear drive 620 to push the pipe from the second hopper through the top plate 470 and the second support plate 520 into the cutting equipment. When it is necessary to push the pipe from the first hopper, in the initial state, the push plate 630 is moved to the position of the top plate 470 to prevent the pipe from the first hopper from rolling into the second hopper through the top plate 470. The second support plate 520 is rotated by the second rotating member 510 and carried away from the groove 471, no longer sealing the top of the first hopper. When it is necessary to push, the linear drive 620 drives the push plate 630 to move and push the pipe at the top of the first hopper toward the cutting equipment, thereby realizing the feeding of the pipe from the first hopper.

[0055] In some specific embodiments, the first limiting frame 310 and the second limiting frame 320 are both slidably mounted on the machine base 100. A drive assembly 700 is installed on the machine base 100, which is used to drive the first limiting frame 310 and the second limiting frame 320 to move closer to or further apart from each other.

[0056] The drive assembly 700 includes a mounting base 710 fixedly mounted on the machine base 100. A second lead screw 720 is rotatably mounted on the mounting base 710. Two transmission plates 730 are connected to the second lead screw 720. The rotation of the second lead screw 720 drives the two transmission plates 730 to move closer to each other or further apart. The transmission plates 730 are fixedly connected to the corresponding first limit frame 310 and second limit frame 320. A handwheel 740 is fixedly mounted on the drive end of the second lead screw 720.

[0057] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 7 As shown, in order to enable the first and second hoppers to accommodate pipes of different specifications, the first limiting frame 310 and the second limiting frame 320 are configured to slide on the upper surface of the machine base 100, and the first limiting frame 310 and the second limiting frame 320 are fixedly connected to their corresponding transmission plates 730. Rotating the handwheel 740 drives the second lead screw 720 to rotate, thereby causing the two transmission plates 730 to move closer to each other or away from each other, thereby driving the first limiting frame 310 and the second limiting frame 320 to also move closer to each other or away from each other, thereby achieving the width of the first and second hoppers so that they can accommodate pipes of different specifications and sizes.

[0058] In some specific embodiments, a support component 800 is provided on the side of the first limiting frame 310 away from the second limiting frame 320. The support component 800 includes a first plate 810 fixedly installed on the first limiting frame 310. A plurality of evenly spaced connecting holes 811 are evenly opened on the first plate 810. A second plate 820 is provided on one side of the first plate 810. An elongated hole 821 is opened on the second plate 820. A screwing component passes through the connecting holes 811 and the elongated hole 821 to fix the first plate 810 and the second plate 820 together.

[0059] Please see Figure 1 , Figure 2 , Figure 3 as well as Figure 8 As shown, in order to move the pipes from the first and second hoppers into the cutting equipment, two support components 800 are fixedly installed on the first limiting frame 310. Each support component 800 includes a first plate 810 connected to the first limiting frame 310. The second plate 820 is then fixedly connected by bolts through connecting holes 811 and elongated holes 821, thereby extending the length of the first plate 810 for guiding the pipes. It can be understood that the length of the second plate 820 overlapping with the first plate 810 can be adjusted to adjust the length of the pipes being guided.

[0060] Please see Figure 1 , Figure 2 as well as Figure 3 As shown, a baffle 900 is vertically installed on one side of the machine 100. The baffle 900 contacts the pipes in the first and second hoppers, so that the pipes can be neatly stacked into the first and second hoppers.

[0061] The working process of this utility model is as follows: In the initial state, the pipes are stacked in the first hopper (composed of the first partition plate 210 of the first limiting frame 310 and the barrier 200) and the second hopper (composed of the second limiting frame 320 and the second partition plate 220), and the support frames 110 on both sides of the machine 100 support the bottom of the pipes. When the second hopper needs to supply material, the second rotating component 510 of the guide assembly 500 drives the second support plate 520 to rotate to the top of the first hopper, which cooperates with the groove 471 of the top plate 470 of the barrier component 200 to form a continuous guide surface; the rotating drive component 440 of the lifting drive device 400 drives the first lead screw 430 to rotate, which drives the lifting plate 420 to descend along the guide column 410 to below the support frame 110; the first rotating component 450 rotates the first support plate 460 to the bottom of the pipe in the second hopper; the lifting plate 420 rises and lifts the pipe to the push plate 630 of the pusher assembly 600; the linear drive component 620 pushes the push plate 630 to push the top pipe through the plane formed by the top plate 470 and the second support plate 520 to the cutting equipment. When the second hopper is exhausted, the second support plate 520 retracts, and new pipes are added to the second hopper. Next, the lifting drive device 400 switches to the bottom of the first hopper to lift the pipes, and the pushing component 600 directly pushes the pipes from the first hopper to the cutting station, realizing uninterrupted feeding cycle.

[0062] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
