Description

Technical Field

[0001] The present invention relates to the technical field of rewinding machines, in particular to a rewinding machine for processing baking paper. Background Art

[0002] A rewinder is a device that rewinds roll materials such as paper, film, and non-woven fabrics. It is widely used in papermaking, printing, packaging, textiles, baking, and other industries. The rewinder can realize the continuous winding of baking paper, and can continuously roll large rolls of base paper or preliminarily processed baking paper into small or large rolls of required specifications, reducing the time interval for manual roll changing and other operations.

[0003] For example, the patent with publication number CN221662145U discloses "a fully automatic rewinding machine for processing baking and barbecue paper", which includes a base, a controller, a feeding mechanism and a processing mechanism. The feeding mechanism includes a stepping motor, a rotating frame and a clamping assembly. The processing mechanism includes a reel, a winding assembly, a pressing assembly and a sliding cutting assembly. A mounting table is fixedly provided on the top of the base, and two L-shaped plates are fixedly provided on the top of the mounting table. The sliding cutting assembly and the pressing assembly are both arranged on the top of the mounting table, and the winding assembly is arranged on the outer wall of the rotating frame. The clamping assembly, the winding assembly, the sliding cutting assembly and the pressing assembly are all electrically connected to the controller.

[0004] However, in the prior art, after a roll of baking paper is rewound, a new rod body needs to be replaced for rewinding. The existing rewinding machine is complicated to operate when changing rolls, and it is necessary to use tools to disassemble many parts before replacing a new paper roll. Fixing the new paper roll requires reinstalling the previously disassembled multiple parts, which makes the entire disassembly and installation process more cumbersome. These problems will increase the time required for changing rolls, resulting in a long change of roll time. The long change of roll time causes the rewinder to stop for a corresponding period of time, which will directly affect the rewinding efficiency. In addition, there are certain differences in the operation when fixing rod bodies of different sizes, and ordinary fixing parts cannot adapt to diverse processing effects. Summary of the invention

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In the present invention, the difficulty of replacing the rod body is reduced by providing a roll-changing assembly. In the roll-changing assembly, a first rod body and a second rod body are provided for rewinding the baking paper. When the first rod body is rewound, it can be immediately transferred out of the rewinder, and then the second rod body can be placed in the rewinder to continue rewinding, thereby shortening the downtime of the rewinder.

In addition, since the position of the limit rod can be freely controlled, rod bodies of different specifications can be fixed during actual use, thereby expanding the scope of application of the device.

[0021] 2. In the present invention, the two connecting plates are connected by a transmission rod. When in use, the semi-open frame can be driven by the first electric cylinder to rotate with the connection point with the positioning plate as the center, so that one of the first rod body or the second rod body enters the limit plate, so as to ensure the stability of the roll changing assembly and prevent the first rod body or the second rod body from shaking during the rewinding process. In addition, a limit circle block is arranged on the load-bearing frame to be connected with the limit plate, which further improves the stability of the entire roll changing assembly in the rewinding machine.

During the cutting process, the baking paper on the roll changing assembly can be stably cut without affecting the use of the entire rewinder. The material changing assembly is arranged at the bottom of the frame and is on the same side of the frame as the roll changing assembly. When replacing the baking paper, the material rod can be removed from the positioning frame, and then the new material rod can be installed on the positioning frame. The structural arrangement on the same side allows the baking paper to move a longer distance in the rewinder, thereby providing more opportunities for auxiliary processing of the baking paper.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Example 1: Reference Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6, Figure 7 , Figure 8 , Fig.11 and Fig.12 As shown: a rewinding machine for baking paper processing, including a frame 1 and a roll changing assembly 2 rotatably mounted on one side of the top of the frame 1, the roll changing assembly 2 includes two connecting plates 203 arranged opposite to each other, and a supporting frame 209 is fixed at both ends of each connecting plate 203, and each supporting frame 209 is provided with a bending rod 216 and a gear ring 207, and a first rod body 204 and a second rod body 205 are rotatably connected between the two opposite gear rings 207.

[0040] The bending rod 216 is a foldable equilateral triangle structure. A docking block 217 is fixedly mounted on the other end of the bending rod 216 . The docking block 217 is used to determine the positions of the first rod body 204 and the second rod body 205 .

[0041] The gear ring 207 is rotatably mounted on one end of the bending rod 216, and a reinforcing rod 219 is fixedly mounted on the inner wall of the gear ring 207 every 120 degrees. A convex rod 206 is fixedly mounted on one side of each reinforcing rod 219, and a transmission frame 210 is slidably connected to the outer wall of each convex rod 206. The other ends of the three transmission frames 210 are rotatably connected to the three corners of the bending rod 216 respectively, and a limiting rod 208 is fixedly mounted on one side of each transmission frame 210. A pinion 218 is meshed and connected at the edge of each gear ring 207, and a hexagonal rod 220 is inserted between the two pinions 218 located at the same end of the frame.

[0042] A plurality of limiting rods 208 are arranged in a ring shape and are equally spaced around the edges of the first rod body 204 and the second rod body 205 , and a plurality of rows of balls are arranged on the outer walls of the limiting rods 208 .

[0043] In this embodiment, the frame 1 serves as the skeleton structure of the rewinding machine and plays a role in supporting and shaping. The roll changing assembly 2 is used to determine the position of the rewinding structure. When in use, one of the first rod body 204 or the second rod body 205 in the roll changing assembly 2 will be in the rewinding machine. When rewinding, one end of the baking paper is wound around the surface of the first rod body 204 or the second rod body 205, and then the first rod body 204 or the second rod body 205 rotates to wind the baking paper onto its own surface to complete the rewinding.

[0044] The roll changing assembly 2 is provided with a bending rod 216 to determine the position of the first rod body 204 and the second rod body 205. The docking block 217 on the bending rod 216 is used to dock the first rod body 204 and the second rod body 205 and determine the rotation center of the first rod body 204 and the second rod body 205. The following description is based on the first rod body 204 as the first structure used. After the rewinding of the first rod body 204 is completed, the roll changing assembly 2 is rotated out of the rewinding machine, and then the connecting plate 203 is rotated to rotate the second rod body 205 to the original position of the first rod body 204. Then the roll changing assembly 2 is re-entered into the rewinding machine to continue rewinding, which can shorten the downtime of the rewinding machine. During the period of using the second rod body 205, the first rod body 204 can be removed;

[0045] like Figure 1 , Figure 3 , Figure 4 , Figure 6 Figure 7 and Figure 8 As shown, a hexagonal rod 220 is inserted between the two pinions 218. The pinion 218 can be rotated only after the hexagonal rod 220 is removed. In the process of removing the first rod body 204, the gear ring 207 is pushed by rotating the pinion 218. During the rotation of the gear ring 207, the transmission frame 210 is pushed through the protruding rod 206. Since one end of the transmission frame 210 is rotatably connected to the corner of the bent rod 216, the rotation center of the bent rod 216 will be restricted. During the rotation of the transmission frame 210, the limiting rod 208 installed thereon will gradually move away from the docking block 217, making room for disassembling the first rod body 204, and then another new first rod body 204 is clamped into the docking block. The first lever 204 is then moved to the position where the second lever 204 is moved and the second lever 204 is moved to the position where the second lever 204 is moved.

[0046] like Fig. 9As shown, during the rotation of the transmission frame 210, the limit rod 208 will first move away from the center area of ​​the bending rod 216. When the gear ring 207 rotates one hundred and eighty degrees, the limit rod 208 is at the farthest point from the center area of ​​the bending rod 216. After the gear ring 207 rotates one circle, the limit rod 208 will return to the nearest point to the center area of ​​the bending rod 216. Balls are provided on the outer wall of the limit rod 208 to reduce friction, which can avoid affecting the normal rotation of the first rod body 204 and the second rod body 205.

[0047] Embodiment 2: Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, both ends of the first rod body 204 and both ends of the second rod body 205 are fixedly installed with gaskets 215, and the edges of the gaskets 215 are provided with notches 214 with a width equal to the diameter of the docking block 217. The first rod body 204 and the second rod body 205 are clamped on the outer wall of the docking block 217 through the notches 214 on the gaskets 215. Two limiting plates 9 are symmetrically fixedly installed on one side of the top of the frame 1. The interiors of the two limiting plates 9 are provided with arc-shaped strip holes 16. Two positioning plates 8 are also fixedly installed on one side of the frame 1. One side of the two connecting plates 203 is fixedly connected with a positioning rod 201, and the other ends of the two positioning rods 201 are rotatably connected with a semi-open frame 7. The two sides of the semi-open frame 7 are respectively connected to the two positioning plates 8 Rotationally connected, a limiting circular block 211 is fixedly installed on one side of each supporting frame 209, the center of the limiting circular block 211 is located on the arc line of the arc-shaped strip hole 16, and the shape of the limiting circular block 211 is adapted to the shape of the arc-shaped strip hole 16, the bottom of the semi-open frame 7 is rotationally connected with the first electric cylinder 14, the other end of the first electric cylinder 14 is rotationally connected to the frame 1, a transmission rod 202 is fixedly connected between the inner sides of the two connecting plates 203, two servo motors 212 are symmetrically fixedly installed on the outer wall of the transmission rod 202, the output shafts of the two servo motors 212 are fixedly connected with a second belt transmission assembly 213, and the second belt transmission assembly 213 is movably connected to the first rod body 204 and the second rod body 205.

[0048] In this embodiment, the gasket 215 is used to connect the docking block 217. When installing the first rod body 204 and the second rod body 205, the notch 214 is aligned with the docking block 217, and then the first rod body 204 and the second rod body 205 are pushed to align their axes with the axis of the docking block 217 to complete the installation of the first rod body 204 and the second rod body 205. Before installing the first rod body 204 and the second rod body 205, the second belt transmission assembly 213 is inserted into the annular groove opened at the ends of the first rod body 204 and the second rod body 205.

[0049] A limit plate 9 is provided at the corner of the top of the frame 1 to determine the position of the roll changing assembly 2. When the roll changing assembly 2 is transferred into the rewinding machine, the first electric cylinder 14 is started to push the half-open frame 7 so that it rotates around the connection point between itself and the positioning plate 8, and the first rod body 204 is transferred into the rewinding machine for rewinding. In this process, the limit round block 211 located on the side of the load-bearing frame 209 will enter the limit plate 9 to improve the stability of the entire roll changing assembly 2 in the rewinding machine.

[0050] A transmission rod 202 is fixedly connected between the two connecting plates 203. The transmission rod 202 and the positioning rod 201 are in the same straight line. The positioning rod 201 is rotatably connected to the semi-open frame 7. When the positions of the first rod body 204 and the second rod body 205 are exchanged, the connecting plate 203 is directly pushed to rotate with the positioning rod 201 as the center.

[0051] During rewinding, the servo motor 212 installed on the transmission rod 202 will drive the first rod 204 or the second rod 205 through the second belt transmission assembly 213 to wind the baking paper onto its own surface to complete the rewinding. The two servo motors 212 correspond to the first rod 204 and the second rod 205 respectively.

The cutting assembly 5 includes two guide rods 501 vertically fixedly installed on the top of the protective shell 15, and one side of the two guide rods 501 is slidably connected with a slider 502. The two guide rods 501 are respectively close to the edge of the protective shell 15, and one side of the two sliders 502 is fixedly connected with a cutting plate 503, one side of the cutting plate 503 is fixedly connected with a connecting block 504, and the top of the connecting block 504 is fixedly connected with a pressing plate 505, and one end of the pressing plate 505 is fixedly connected with a second electric cylinder 506, and the second electric cylinder 506 is parallel to the guide rod 501.

When rewinding, the second electric cylinder 506 drives the pressing plate 505, and the connecting block 504 under the pressing plate 505 pushes the cutting plate 503 to move along the direction of the guide rod 501 to complete the cutting of the baking paper. The cutting plate 503 is slidably connected to the guide rod 501 through the slider 502, so as to determine the moving route of the cutting plate 503 and ensure that it can fully contact the baking paper.

[0054] Embodiment 4: Figure 1 , Figure 2 , Figure 3 and Fig.10As shown, a material changing assembly 6 is rotatably installed at the bottom of the frame 1, and the material changing assembly 6 includes a positioning frame 604, which is rotatably installed inside the frame 1, and blocks 602 are movably inserted at both ends of one side of the positioning frame 604, and a material rod 601 is rotatably connected between the two blocks 602, and a limiting ring 603 is fixedly installed on one side of the block 602, and an extension side rod 605 is fixedly connected to one end of the positioning frame 604, and the extension side rod 605 and the positioning frame 604 are perpendicular to each other, and the extension side rod 605 passes through the frame 1, and a casing 3 is fixedly installed on one side of the frame 1, and a reduction motor 10 is fixedly installed on the inner wall of the casing 3, and the output end of the reduction motor 10 is fixedly connected to a first belt transmission assembly 11, and the first belt transmission assembly 11 is transmission-connected to two first roller rods 12 and a second roller rod 13 arranged on the same horizontal line, and a cover 4 is fixedly installed on the top of the frame 1.

[0055] In this embodiment, a first roller bar 12 and a second roller bar 13 are arranged inside the frame 1, wherein the first roller bar 12 is used to change the direction of the baking paper, and the second roller bar 13 is located near the roll changing assembly 2, and can play a role in pressing the baking paper during the rewinding process. The cover 4 arranged on one side of the top of the frame 1 is used to place other auxiliary equipment, including but not limited to a cleaning device and a static electricity removal device. At the same time, another auxiliary rolling roller is arranged at the bottom of the frame 1 to determine the position of the baking paper;

[0056] The material rod 601 in the material changing assembly 6 is a rod body with baking paper wound on it. Before rewinding, it is first necessary to sleeve the limit ring 603 onto the two ends of the material rod 601, and then insert the block 602 into the end of the positioning frame 604, and then rotate the entire positioning frame 604 by extending the side rod 605, so that the material rod 601 enters the interior of the rewinder, and then overlap the baking paper on the auxiliary winding roller, the first roller rod 12 and the second roller rod 13 at the bottom of the frame 1, start the reduction motor 10 arranged in the casing 3, and mobilize the first roller rod 12 and the second roller rod 13 at the same time through the first belt transmission assembly 11 to ensure the normal movement of the baking paper.

[0057] The use method and working principle of the device: when in use, firstly, the limiting ring 603 is sleeved onto the two ends of the material rod 601, and then the clamping block 602 is inserted into the end of the positioning frame 604, and then the entire positioning frame 604 is rotated by extending the side rod 605, so that the material rod 601 enters the interior of the rewinding machine, and then the baking paper is overlapped on the auxiliary roller, the first roller rod 12 and the second roller rod 13 at the bottom of the frame 1;

[0058] The first electric cylinder 14 is started to push the half-open frame 7 so that it rotates around the connection point between the half-open frame 7 and the positioning plate 8, and the first rod 204 is transferred into the rewinding machine. Then, the servo motor 212 and the reduction motor 10 in the housing 3 are started at the same time. The servo motor 212 drives the first rod 204 or the second rod 205 through the second belt transmission assembly 213 to wind the baking paper onto its surface to complete the rewinding. The reduction motor 10 simultaneously mobilizes the first roller 12 and the second roller 13 through the first belt transmission assembly 11 to ensure the normal movement of the baking paper.

[0059] After the paper is rewound to a certain thickness, the second electric cylinder 506 drives the pressing plate 505, and the connecting block 504 below the pressing plate 505 pushes the cutting plate 503 to move along the direction of the guide rod 501 to cut the baking paper. Then, the first electric cylinder 14 pushes the semi-open frame 7 to rotate the first rod body 204 out of the rewinder.

[0060] Then, the connecting plate 203 is rotated to rotate the second rod 205 to the original position of the first rod 204, and the first electric cylinder 14 then transfers the second rod 205 into the rewinding machine to continue rewinding. During the period of using the second rod 205, the first rod 204 can be removed, and the gear ring 207 is pushed by rotating the pinion 218. During the rotation of the gear ring 207, the transmission frame 210 is pushed by the convex rod 206.

[0061] As the transmission frame 210 rotates with the corner of the bending rod 216 as the center, the limiting rod 208 installed thereon will gradually move away from the docking block 217, making room for disassembling the first rod body 204, and then another new first rod body 204 is clamped onto the docking block 217, and then the pinion 218 is rotated to re-clamp the limiting rod 208 onto the first rod body 204, and the above steps are repeated after the second rod body 205 is rewound.

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