Description

Technical Field

[0001] This utility model belongs to the field of feeding devices, and specifically relates to an automatic feeding device for heavy-duty roll sheet. Background Technology

[0002] In modern industrial production, many products (such as the housings of electrical equipment, building decorative panels, and automotive parts) require a thin sheet of iron to protect their surfaces. The thickness of the sheet is generally between 1mm and 1.5mm to enhance the product's corrosion resistance, wear resistance, and aesthetics.

[0003] Since sheet metal is supplied in rolls, each roll often weighs several tons. In traditional production processes, handling these rolls of thin sheet metal for subsequent processing (such as cutting, stamping, and forming) mainly relies on overhead cranes for hoisting. Specifically, the overhead crane suspends the sheet metal roll and slowly rotates the drum, gradually unfolding the sheet metal for feeding. This process has several significant drawbacks:

[0004] 1. Slow feeding speed: Due to the limitations of crane operation precision and drum rotation, the sheet metal stretching speed is difficult to increase, resulting in low overall production efficiency.

[0005] 2. High operational difficulty: The operation of the crane requires professional personnel and a high level of skill. During the sheet metal extension process, the crane position, speed, and drum rotation angle must be precisely controlled. The slightest carelessness may cause the sheet metal to tear, deform, or deviate from the predetermined path.

[0006] 3. Inefficiency: Due to the slow feeding speed and complicated operation, the processing cycle of each roll of sheet metal is significantly extended, affecting the overall production line capacity.

[0007] 4. Severe occupation of overhead crane resources: During the sheet metal extension and feeding process, the overhead crane needs to be occupied for a long time, which makes it impossible to carry out other operations that require overhead crane hoisting, further reducing the utilization rate of production resources.

[0008] 5. High operational safety risks: Overhead crane lifting operations inherently carry safety risks such as falls from heights and being struck by objects. Furthermore, the heavy weight of the sheet metal rolls and their susceptibility to dynamic imbalance during extension further exacerbate these safety hazards. Utility Model Content

[0009] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a heavy-duty automatic feeding device for thin rolls, so as to solve the above-mentioned drawbacks of overhead crane feeding. It is of great significance for improving production efficiency, reducing operation difficulty, reducing resource consumption and ensuring production safety.

[0010] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0011] A heavy-duty automatic feeding device for roll sheet metal includes a frame, a drive mechanism, and rollers. The frame includes two sets of synchronously linked lifting platforms, each with casters at the bottom. The upper and lower parts of one end of each lifting platform are connected by a connecting rod, while the other end remains open. A motor mount is located on one side of the upper connecting rod, and a bearing seat is located on the upper side. The rollers are rotatably mounted on the bearing seats. Each roller includes a central shaft with several first and second connecting plates. One end of each of the first and second connecting plates is connected to a T-shaped support plate for supporting the roll sheet metal. The drive mechanism includes a motor mounted on the motor mount. A drive pulley is connected to the motor's output shaft, and a driven pulley is located at one end of the central shaft. The drive pulley and the driven pulley are connected by a transmission belt.

[0012] Furthermore, the lifting platform is a hydraulic lifting platform or a chain lifting platform.

[0013] Furthermore, the outer surface of the T-shaped support plate is arc-shaped.

[0014] Furthermore, the frame has a detachable support arm at its open end, and the lifting platform has a fixing hole at its end. The two ends of the support arm are connected to the lifting platform by fixing pins. The central shaft has a bearing at its end, and the bearing is located on the support arm after the support arm is installed.

[0015] Furthermore, the support arm has a slot in the middle for accommodating the bearing and limiting its position.

[0016] Furthermore, a baffle is provided at one end of the central shaft for positioning and protection when the roller shaft is inserted into the roll sheet.

[0017] Furthermore, the connecting plate includes a first sleeve, with a first telescopic rod slidably connected to each end of the first sleeve. One end of the first telescopic rod is fixedly connected to the lifting platform. The first telescopic rod is provided with a plurality of first adjustment holes, and the first sleeve is provided with first adjustment bolts that cooperate with the first adjustment holes at both ends. The support arm includes a second sleeve, with a second telescopic rod slidably connected to each end of the second sleeve. The second telescopic rod is provided with a plurality of second adjustment holes, and the second sleeve is provided with second adjustment bolts that cooperate with the second adjustment holes at both ends.

[0018] Furthermore, a number of threaded sleeves are provided on one side of the lifting platform, and the threaded sleeves are connected to support legs.

[0019] Furthermore, the roller shaft has a hollow structure, and two sets of sliding bushings are slidably connected to the roller shaft. The lower end of the first connecting plate is hinged to the central shaft, and the upper end is hinged to the T-shaped support plate. The lower end of the second connecting plate is hinged to the sliding bushing, and the upper end is hinged to the T-shaped support plate. The two sets of first connecting plates at both ends of the central shaft are parallel to each other, and the two sets of second connecting plates are also parallel to each other. One end of the roller shaft is provided with a guide groove, and the roller shaft is provided with a tensioning mechanism. The tensioning mechanism includes a lead screw, which is rotatably connected to one end of the central shaft. An adjusting bushing is threaded onto the lead screw. The adjusting bushing is connected to the sliding bushing near the open end of the frame by a connecting bolt, and the connecting bolt is spaced apart in the guide groove.

[0020] The beneficial effects of this utility model are:

[0021] 1) This utility model realizes automatic feeding of thin rolls, reduces labor intensity, and improves overall work efficiency. Since there is no need to use cranes or other hoisting tools, it reduces the difficulty of operation and reduces the occupation of crane resources.

[0022] 2) A detachable support arm is provided at the open end of the frame. The support arm is removed before the roller is inserted into the roll sheet, and the support arm is installed at the open end of the frame after the roller is inserted into the roll sheet, which enhances the stability of the roll sheet feeding.

[0023] 3) By setting bearings on the central shaft and setting slots on the support arm to limit the bearings, the shaking or deviation of the roller shaft caused by uneven force during rotation is effectively prevented, and the stability of the roller shaft during feeding is enhanced.

[0024] 4) The connecting plate and support arm are designed as telescopic structures, which makes it easy to adjust the distance between the two lifting platforms. This makes it suitable for feeding thin rolls of different specifications, thus improving the versatility of the device.

[0025] 5) By setting a tensioning mechanism, the support range of the T-shaped support plate can be flexibly adjusted according to the inner diameter of the roll sheet. Whether it is a large-diameter or small-diameter roll sheet, a tight fit can be achieved by adjusting the unfolding degree of the T-shaped support plate, thereby expanding the applicability of the device.

[0034] The following will be combined with the appendix Figures 1-7 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0036] like Figure 1 As shown, a heavy-duty automatic feeding device for sheet metal rolls includes a frame 1, a drive mechanism 2, and a roller 3. Figure 2 As shown, the frame 1 includes two sets of synchronously linked lifting platforms 11, as follows: Figure 3As shown, both sets of lifting platforms 11 are equipped with casters 17 at their bottoms. The upper and lower parts of one end of each set of lifting platforms 11 are connected by a connecting rod 12, while the other end is open. A motor seat 13 is located on one side of the upper connecting rod 12, and a bearing seat 14 is located on the upper side. The roller 3 is rotatably mounted on the bearing seat 14. The roller 3 includes a central shaft 31, on which several first connecting plates 32 and second connecting plates 33 are provided. One end of each of the first connecting plates 32 and second connecting plates 33 is connected to a T-shaped support plate 34 for supporting the thin sheet on the roll. Figure 1 As shown, the drive mechanism 2 includes a motor 21 mounted on a motor base 13. A drive pulley 22 is connected to the output shaft of the motor 21, and a driven pulley 23 is provided at one end of the central shaft 31. The drive pulley 22 and the driven pulley 23 are connected by a transmission belt 24.

[0037] When feeding the roll sheet, push the device to one side of the roll sheet so that the opening of the device faces the roll sheet. Then adjust the height of the two sets of lifting platforms 11 so that the height of the roller shaft 3 is aligned with the center of the roll sheet. Then continue to push the device to one side of the roll sheet so that the roller shaft 3 is inserted into the center of the roll sheet. Then control the lifting platform 11 to lift the roll sheet. When feeding, start the motor 21. The motor 21 drives the roller shaft 3 to rotate through the belt drive belt 24, thereby realizing automatic feeding of the roll sheet, reducing labor intensity and improving overall work efficiency. Since there is no need to use cranes or other hoisting tools, the operation difficulty is reduced and the occupation of crane resources is reduced.

[0038] Lifting platform 11 adopts a hydraulic lifting platform or a chain lifting platform, such as Figures 1-3 As shown, in this embodiment, the lifting platform 11 is a hydraulic lifting platform.

[0039] The outer surface of the T-shaped support plate 34 is arc-shaped, which increases the support area between the T-shaped support plate 34 and the inner wall of the roll sheet, enhances the stability of the roll sheet support, and reduces the wear of the T-shaped support plate 34 on the roll sheet.

[0040] like Figure 2 As shown, the open end of the frame 1 is provided with a detachable support arm 15, the end of the lifting platform 11 is provided with a fixing hole 16, and the two ends of the support arm 15 are connected to the lifting platform 11 through fixing pins 156; the end of the central shaft 31 is provided with a bearing 38, and after the support arm 15 is installed, the bearing 38 is located on the support arm 15.

[0041] After the roller shaft 3 is inserted into the center of the thin sheet on the roll, the detachable support arm 15 is installed at the open end of the frame 1 and connected to the fixing hole 16 at the end of the lifting platform 11 through the fixing pin 156. After the support arm 15 is installed, the bearing 38 at the end of the roller shaft 3 is firmly supported on the support arm 15, which effectively prevents the roller shaft 3 from shaking or shifting due to uneven force during rotation, significantly enhances the stability of the roller shaft 3, and ensures the smooth operation of the feeding process.

[0042] like Figure 5 As shown, the support arm 15 has a groove 152 in the middle for accommodating the bearing 38 and limiting its position; the bearing 38 at the end of the roller shaft 3 is limited in the groove 152 in the middle of the support arm 15, which effectively prevents the roller shaft 3 from shaking or shifting due to uneven force during rotation, and enhances the stability of the roller shaft 3 during feeding.

[0043] like Figure 6 As shown, a baffle 39 is provided at one end of the central shaft 31 for positioning and protection when the roller shaft 3 is inserted into the roll sheet, so that the roll sheet can be installed quickly and accurately in the designated position. At the same time, the baffle 39 can also effectively prevent the roll sheet from hitting the frame 1 during installation or feeding, thus improving the safety and reliability of the device.

[0044] like Figure 3 , Figure 4 As shown, the connecting plate includes a first sleeve 123, with a first telescopic rod 121 slidably connected to each end of the first sleeve 123. One end of the first telescopic rod 121 is fixedly connected to the lifting platform 11. The first telescopic rod 121 is provided with a plurality of first adjustment holes 122. The first sleeve 123 is provided with first adjustment bolts 124 at both ends that cooperate with the first adjustment holes 122. The support arm 15 includes a second sleeve 151, with a second telescopic rod 154 slidably connected to each end of the second sleeve 151. The second telescopic rod 154 is provided with a plurality of second adjustment holes 155. The second sleeve 151 is provided with second adjustment bolts 153 at both ends that cooperate with the second adjustment holes 155. The telescopic connecting rod 12 and the support arm 15 facilitate adjustment of the distance between the two lifting platforms 11, and are suitable for use when feeding thin rolls of different specifications, thus improving the versatility of the device.

[0045] like Figure 3 As shown, the lifting platform 11 has several threaded sleeves 18 on one side, with support legs 19 connected to the internal threads of the sleeves 18. During feeding, the support legs 19 at different positions are independently adjusted according to the flatness of the ground to ensure that the entire device is in a horizontal state, thus improving the stability of feeding. In addition, when the feeding operation begins, the support legs 19 are rotated to make full contact with the ground, lifting the casters 17 off the ground, preventing the device from moving due to the rolling of the casters 17, further ensuring the stability and safety of the feeding process.

[0046] like Figure 6 , Figure 7 As shown, the roller shaft 3 has a hollow structure. Two sets of sliding bushings 35 are slidably connected on the roller shaft 3. The lower end of the first connecting plate 32 is hinged to the central shaft 31, and the upper end is hinged to the T-shaped support plate 34. The lower end of the second connecting plate 33 is hinged to the sliding bushing 35, and the upper end is hinged to the T-shaped support plate 34. The two sets of first connecting plates 32 at both ends of the central shaft 31 are parallel to each other, and the two sets of second connecting plates 33 are also parallel to each other. One end of the roller shaft 3 is provided with a guide groove 311. The roller shaft 3 is provided with a tensioning mechanism, which includes a lead screw 37. The lead screw 37 is rotatably connected to one end of the central shaft 31. An adjusting bushing 36 is threadedly connected to the lead screw 37. The adjusting bushing 36 is connected to the sliding bushing 35 near the open end of the frame 1 by a connecting bolt 361, and the connecting bolt 361 is intermittently set in the guide groove 311.

[0047] By manually or electrically rotating the lead screw 37, the adjusting bushing 36 and the sliding bushing 35 can be moved left and right, thereby retracting and unfolding the T-shaped support plate 34. Before the roller 3 is inserted into the roll sheet, the T-shaped support plate 34 is reduced to a size smaller than the inner hole size of the roll sheet to facilitate smooth insertion; after insertion, the T-shaped support plate 34 is expanded to abut against the inner wall of the roll sheet for stable fixation.

[0048] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
