Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for strip processing, specifically a feeding mechanism for cutting equipment. Background Technology

[0002] In the field of strip cutting and processing, in order to achieve continuous production, the roll strip (strip roll) needs to be stably installed and unwound through the feeding mechanism so that the strip strip is continuously conveyed to the cutting equipment for processing. At present, among the commonly used feeding methods in the industry, the air expansion roller is the core component for fixing and driving the strip roll. It expands by inflation and fits into the inner hole of the strip roll to realize the unwinding operation.

[0003] A search revealed that patent publication number CN219310182U discloses an automatic tape cutting device, including a main frame, a cutting device, and a loading platform. The loading platform is located on one side of the main frame, and a conveying roller is mounted on the main frame. A pressure roller is also mounted above the conveying roller and can move up and down. The cutting device is located on the side of the main frame away from the loading platform and includes an adjusting block, a lower blade, a turntable, and an upper blade. The upper blade is fixedly connected to the turntable, and the lower blade is mounted on the adjusting block. This invention, through the setting of the adjusting block and the turntable, allows for adjustment of the angles of the lower and upper blades, thereby achieving cutting at a specified angle. Furthermore, the setting of the pressure block prevents the tape from moving during cutting, thus improving the dimensional accuracy of the cut sheet material and enhancing product quality.

[0004] In actual use, the existing feeding mechanism for cutting equipment has a large weight of the material roll itself, and the dynamic force generated by tension fluctuations and inertia during the unwinding process will directly act on the air expansion roll. The structural strength of the air expansion roll is difficult to withstand such loads for a long time, and it is prone to bending, deformation or even damage. This not only affects the unwinding stability, but also increases the equipment maintenance cost and downtime. Therefore, a feeding mechanism for cutting equipment is designed. Utility Model Content

[0005] In view of the defects or deficiencies of the feeding mechanism used in cutting equipment, the purpose of this utility model is to provide a feeding mechanism for cutting equipment that can effectively share the weight of the material roll itself and the dynamic force generated during the unwinding process, greatly reduce the load on the air expansion roller, and prevent it from bending, deforming or being damaged due to excessive force.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0007] This utility model provides a feeding mechanism for a cutting equipment, including a mounting frame. A first support component and a second support component are respectively provided on the upper two sides of the mounting frame for supporting a strip roller, with the strip roller located between the first and second support components. An adjustment component is provided on the mounting frame for adjusting the distance between the first and second support components. A drive component for driving the strip roller to unwind is provided at the rear end of the mounting frame. A mounting base plate is installed at the rear end of the bottom of the mounting frame, and a hydraulic telescopic rod for driving the drive component to move linearly in the Z-axis direction is installed at the rear end of the top of the mounting base plate.

[0008] Both the first support assembly and the second support assembly are provided with a fixing plate. The top of the fixing plate is equipped with three sets of support structures arranged in a rectangular array. The support structures are provided with support rollers. The connecting shafts on the two end walls of the support rollers are respectively installed in the bearings on the outer walls of the two connecting plates, and the connecting plates are installed on the top of the fixing plate.

[0009] Preferably, the drive assembly is provided with an air roller, and the connecting shaft on one end wall of the air roller passes through the bearing on the end face of the mounting plate and is connected to the first geared motor through a coupling. The first geared motor is installed on the top of the support block, and the support block is installed above the rear end face of the mounting plate. The mounting plate is installed on the top of the moving block.

[0010] Preferably, the rear end face of the movable block is mounted on the telescopic end of the hydraulic telescopic rod, and sliders are provided on both sides of the bottom end of the movable block. Slide rails are installed on both sides of the top end of the mounting base plate, and the sliders on the movable block and the slide rails on the mounting base plate are slidably connected.

[0011] Preferably, the adjusting assembly is provided with a rotating shaft, the two ends of which pass through bearings on the outer walls of two side plates respectively. The two side plates are respectively installed on both sides of the top of the mounting frame, and a driven pulley is installed at one end of the rotating shaft. The driven pulley is connected to the driving pulley through a transmission belt. The driving pulley is installed on the output shaft of the second reduction motor, and the second reduction motor is installed on one side of the bottom inner side of the mounting frame.

[0012] Preferably, a first movable plate and a second movable plate are respectively installed on both sides of the outer wall of the rotating shaft. Threaded holes are opened at the center of the end walls of the first movable plate and the second movable plate.

[0015] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:

[0016] 1. In this utility model, through a series of coordinated structural arrangements, when the worker installs and unwinds the strip roll, continuously conveying the strip to the cutting equipment for processing, the worker places the strip roll between two adjacent support structures in the X-axis direction using external equipment. The worker then activates the hydraulic telescopic rod, causing it to extend and retract, moving the air roller on the drive assembly into the inner hole of the strip roll. The air roller is then inflated, expanding to fit against the inner hole of the strip roll. The worker then activates the second reduction motor on the drive assembly. When the geared motor starts, it drives the strip roll on the air expansion roller to rotate and unwind. Since the strip roll is placed between two adjacent support structures in the X-axis direction, the support roller on the support structure supports the strip roll. When the strip roll rotates, it also drives the support roller to rotate. Thus, the support roller can effectively share the weight of the strip roll itself and the dynamic force generated during the unwinding process, greatly reducing the load on the air expansion roller, preventing it from bending, deforming or being damaged due to excessive force, extending the service life of the air expansion roller, reducing equipment maintenance costs and downtime, and ensuring the stable operation of the unwinding process.

[0017] 2. In this utility model, through the coordinated arrangement of a series of structures, since the first support component and the second support component are each provided with three sets of support structures arranged in a rectangular array, 1-3 strip rolls can be placed between the first support component and the second support component, so that 1-3 strip rolls can be installed and unwound at the same time, which can meet the needs of cutting the strips on 1-3 strip rolls simultaneously and improve production efficiency.

[0032] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0033] It should be noted that the following detailed description is exemplary and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0034] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0035] like Figure 1-6 As shown, a feeding mechanism for a cutting equipment includes a mounting frame 100. A first support component 300 and a second support component 400 for supporting a strip roller are respectively provided on the upper two sides of the mounting frame 100, and the strip roller is located between the first support component 300 and the second support component 400. An adjustment component 500 for adjusting the distance between the first support component 300 and the second support component 400 is provided on the mounting frame 100. A drive component 600 for driving the strip roller to unwind is provided at the rear end of the mounting frame 100. A mounting base plate 110 is installed at the rear end of the bottom of the mounting frame 100. A hydraulic telescopic rod 200 for driving the drive component 600 to move linearly in the Z-axis direction is installed at the rear end of the top of the mounting base plate 110.

[0036] Both the first support assembly 300 and the second support assembly 400 are provided with a fixing plate 310. The top of the fixing plate 310 is equipped with three sets of support structures 320 arranged in a rectangular array. The support structures 320 are equipped with support rollers 321. The connecting shafts on the two end walls of the support rollers 321 are respectively installed in the bearings on the outer walls of the two connecting plates 322. The connecting plates 322 are installed on the top of the fixing plate 310. Since both the first support assembly 300 and the second support assembly 400 are provided with three sets of support structures 320 arranged in a rectangular array, 1-3 strip rolls can be placed between the first support assembly 300 and the second support assembly 400. This allows 1-3 strip rolls to be installed and unwound simultaneously, which can meet the requirement of simultaneous cutting of the strips on 1-3 strip rolls and improve production efficiency.

[0037] An air expansion roller 650 is provided on the drive assembly 600. The connecting shaft on one end wall of the air expansion roller 650 passes through the bearing on the end face of the mounting plate 620 and is connected to the first reduction motor 610 through a coupling. The first reduction motor 610 is installed on the top of the support block 630, and the support block 630 is installed above the rear end face of the mounting plate 620. The mounting plate 620 is installed on the top of the moving block 640. When the first reduction motor 610 starts, it will drive the air expansion roller 650 to rotate. When the air expansion roller 650 rotates, it will drive the material roll on the air expansion roller 650 to perform unwinding operation.

[0038] The rear end of the movable block 640 is mounted on the telescopic end of the hydraulic telescopic rod 200. Slider blocks are provided on both sides of the bottom end of the movable block 640, and slide rails are installed on both sides of the top end of the mounting base plate 110. The sliders on the movable block 640 and the slide rails on the mounting base plate 110 are slidably connected. When the hydraulic telescopic rod 200 is started, it will drive the movable block 640 to move linearly in the Z-axis direction. When the movable block 640 moves linearly in the Z-axis direction, it will indirectly drive the air roller 650 to move linearly in the Z-axis direction. Because the sliders on the movable block 640 and the slide rails on the mounting base plate 110 are slidably connected, the movement of the movable block 640 can be limited and guided.

[0039] The adjusting assembly 500 is provided with a rotating shaft 550. The two ends of the rotating shaft 550 pass through bearings on the outer walls of the two side plates 560 respectively. The two side plates 560 are respectively installed on both sides of the top of the mounting frame 100. A driven pulley 530 is installed on one end of the rotating shaft 550. The driven pulley 530 is connected to the driving pulley 520 through a transmission belt. The driving pulley 520 is installed on the output shaft of the second reduction motor 510. The second reduction motor 510 is installed on one side of the bottom inner side of the mounting frame 100.

[0040] A first movable plate 540 and a second movable plate 570 are respectively installed on both sides of the outer wall of the rotating shaft 550. Threaded holes are provided at the center of the end walls of both the first movable plate 540 and the second movable plate 570. Left-hand threads and right-hand threads are respectively provided on both sides of the circumferential outer wall of the rotating shaft 550. The threaded holes on the first movable plate 540 are threadedly engaged with the left-hand threads on the rotating shaft 550, and the threaded holes on the second movable plate 570 are threadedly engaged with the right-hand threads on the rotating shaft 550. When the second reduction motor 510 starts, it drives the rotating shaft 550. When the shaft 550 rotates forward or backward, the first moving plate 540 and the second moving plate 570 will move linearly on the outer wall of the shaft 550. The first moving plate 540 and the second moving plate 570 move in opposite directions, thereby adjusting the distance between the first support component 300 and the second support component 400. The adjustable distance between the first support component 300 and the second support component 400 allows for flexible adjustment of the support position according to the diameter of the strip roller, ensuring stable support for the strip roller.

[0041] Slider blocks are installed at both the front and rear ends of the bottom of the first movable plate 540 and the second movable plate 570, and slide rails are installed at both the front and rear ends of the top of the mounting frame 100. The sliders on the first movable plate 540 and the second movable plate 570 are slidably connected to the slide rails on the mounting frame 100. Because the sliders on the first movable plate 540 and the second movable plate 570 are slidably connected to the slide rails on the mounting frame 100, the movement of the first movable plate 540 and the second movable plate 570 can be limited and guided.

[0042] The fixing plate 310 on the first support assembly 300 is mounted on the top of the second movable plate 570, and the fixing plate 310 on the second support assembly 400 is mounted on the top of the first movable plate 540.

[0043] Working principle: When in use, after connecting to an external power source, the operator installs and unwinds the strip roll, continuously feeding the strip to the cutting equipment for processing. The operator places the strip roll between two adjacent support structures 320 in the X-axis direction using external equipment. Then, the operator activates the hydraulic telescopic rod 200, causing it to extend and retract, moving the air roller 650 on the drive assembly 600 into the inner hole of the strip roll. The air roller 650 is then inflated, expanding to fit against the inner hole of the strip roll. The operator then activates the second reduction motor 510 on the drive assembly 600. When the high-speed motor 510 starts, it drives the strip roll on the air expansion roller 650 to rotate and unwind. Since the strip roll is placed between two adjacent support structures 320 in the X-axis direction, the support roller 321 on the support structure 320 supports the strip roll. When the strip roll rotates, it also drives the support roller to rotate. Thus, the support roller can effectively share the weight of the strip roll itself and the dynamic force generated during the unwinding process, greatly reducing the load on the air expansion roller 650, preventing it from bending, deforming or being damaged due to excessive force, extending the service life of the air expansion roller 650, reducing equipment maintenance costs and downtime, and ensuring the stable operation of the unwinding process.

[0044] The above description is merely a preferred embodiment of this utility model and is not intended to limit the invention. For those skilled in the art, various modifications and variations can be made to this invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
