Technical Field
[0001] This utility model belongs to the field of papermaking technology, and in particular relates to a papermaking winding device that is easy to change rolls. Background Technology
[0002] Papermaking refers to the process of making paper from raw materials such as cellulose through a series of processing steps. This process includes the selection of raw materials, the preparation of pulp, and the operation of papermaking machines. Papermaking is a very important industrial production, widely used in books, newspapers, packaging, etc. In the papermaking process, a winding drum is needed as a winding device to wind up the paper. However, most existing papermaking winding devices directly use bolts to limit the winding drum to the frame, and then connect an external motor to one end of the winding drum to drive it. However, the bolt fixing method is cumbersome, and tools are also needed to disassemble the fastened bolts when changing rolls, which is very inconvenient for subsequent roll changes and greatly reduces the winding efficiency of the winding device for paper. Utility Model Content
[0003] The purpose of this invention is to provide a paper-making winding device that is easy to change rolls. It employs a multi-directional positioning component and a double-locking structure, allowing the push block to be quickly fixed to the side plate, thereby quickly limiting the winding drum on the side plate. This facilitates rapid docking of the external motor with the winding drum. The mounting frame for the external motor is freely retractable and has a positioning structure, and can be directly fixed to the side of one set of side plates for easy docking with the winding drum. The overall assembly of the winding drum uses a snap-fit method, eliminating the need for bolt tightening and limiting. Disassembly is equally simple, requiring only the pulling of the T-shaped bracket and T-shaped side frame. This allows users to quickly change rolls, thus solving the aforementioned technical problems.
[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A paper winding device for easy roll changing includes a mounting plate fixed on a frame and a winding drum located above the mounting plate for winding the paper.

A multi-directional positioning component is provided on the side plate for cooperating with the winding drum. The multi-directional positioning component includes push blocks rotatably mounted at both ends of the winding drum. A fixing slot for inserting the push blocks is opened on the front of the side plate. Bent ends are rotatably mounted on the top and bottom of each set of side plates and engaged with the push blocks. The front blocking frame has T-shaped brackets inserted on the side of the upper and lower sets of blocking frames that are far apart from each other. The side of the two adjacent sets of T-shaped brackets that are close to each other passes through the fixing groove and is inserted into the preset insertion port of the push block. Each set of T-shaped brackets is wound with a first spring, and the two ends of the first spring are fixed to the protruding end of the T-shaped bracket and the blocking frame. The side of the blocking frame is fixed with an extension bracket that is snapped onto the side plate. Each set of extension brackets is inserted with a T-shaped side frame. One end of the T-shaped side frame is inserted into the preset square hole of the side plate. Each set of T-shaped side frames is wound with a second spring, and the two ends of the second spring are fixed to the protruding end of the T-shaped side frame and the extension bracket.
[0005] Preferably, rubber blocks are attached to the back sides of the blocking frames that are close to each other, and the sides of the rubber blocks that are close to each other are fixed to the side plate.
[0006] Preferably, electric push rods are fixed on both sides of the top back of the back frame, and the piston rods of the electric push rods are fixed on the corresponding side plates.
[0007] Preferably, the back sides of the top and bottom of the push block are both inclined inwards.
[0008] Preferably, each of the side plates is provided with a square rod inserted laterally, and the two ends of the square rod are fixed to both sides of the inner cavity of the sliding groove.

[0010] Preferably, each of the side panels is fixed with a reinforcing seat whose back is attached to the back frame.
[0011] The beneficial effects of this utility model are: This invention, by setting up a multi-directional positioning component and adopting a double locking structure, can quickly fix the push block on the side plate, thereby quickly limiting the winding drum on the side plate. This allows for quick docking of the external motor with the winding drum. The mounting frame of the external motor is freely retractable and has a positioning structure. It can be directly fixed to the side of one of the side plates for easy docking with the winding drum. The overall assembly process of the winding drum adopts a snap-fit method, eliminating the need for bolt tightening and limiting. Disassembly is equally simple, requiring only the pulling of the T-shaped bracket and T-shaped side frame, making it convenient for users to quickly change the winding drum.
[0012] This invention incorporates rubber blocks that, through their elastic rebound, provide a counter-pushing force to the blocking frame, ensuring a more secure connection between the T-shaped bracket and the T-shaped side frame and preventing detachment.
[0013] This invention incorporates an electric push rod to change the position of the side plate, facilitating precise adjustment of the side plate position according to the size of the winding drum and improving the overall applicability of the device.

Please note that, to clearly demonstrate the structure of the components in the embodiments of this utility model, the figures are not drawn to the same scale. The same reference numerals are used to indicate the same parts.
[0023] Example 1: A paper winding device for easy roll changing includes a mounting plate 1 fixed to a frame and a winding drum 2 located above the mounting plate 1 for winding the paper. A back frame 3 is fixed to the back of the mounting plate 1. A controller is located on the right side of the front of the back frame 3. Sliding grooves 5 are symmetrically opened on the left and right sides of the back frame 3. A side plate 4 is slidably installed in each set of sliding grooves 5. A multi-directional positioning component is provided on the side plate 4 to cooperate with the winding drum 2. The multi-directional positioning component includes push blocks 12 rotatably mounted at both ends of the winding drum 2. A fixing groove 11 for inserting the push blocks 12 is opened on the front of the side plate 4. A blocking bracket 13 with a bent end that engages with the front of the push block 12 is rotatably mounted at the top and bottom of each set of side plates 4. The upper and lower blocking brackets are connected in a series of blocks. T-shaped brackets 14 are inserted on the side of the baffle 13 that are far apart from each other. The side of two adjacent T-shaped brackets 14 that are close to each other passes through the fixing groove 11 and is inserted into the preset insertion port of the push block 12. Each T-shaped bracket 14 is wound with a first spring 15 and the two ends of the first spring 15 are fixed to the protruding end of the T-shaped bracket 14 and the baffle 13. An extension bracket 16 that is snapped onto the side plate 4 is fixed on the side of the baffle 13. Each extension bracket 16 is inserted with a T-shaped side bracket 17. One end of the T-shaped side bracket 17 is inserted into the preset square hole of the side plate 4. Each T-shaped side bracket 17 is wound with a second spring 18 and the two ends of the second spring 18 are fixed to the protruding end of the T-shaped side bracket 17 and the extension bracket 16.
[0024] Specifically, this utility model, by setting up a multi-directional positioning component, utilizes the snap-fit between the fixing groove 11 and the push block 12 to initially position the take-up drum 2. The design of the blocking frame 13, T-shaped bracket 14, first spring 15, extension bracket 16, T-shaped side frame 17 and second spring 18 can form a double locking structure for the push block 12, which can quickly fix the push block 12 on the side plate 4, thereby quickly limiting the take-up drum 2 on the side plate 4, so that the external motor can be quickly connected to the take-up drum 2. The mounting frame of the external motor can be freely extended and retracted and has a positioning structure, and can be directly fixed to the side of one of the side plates 4, which is convenient for quick connection with the take-up drum 2. The overall assembly process of the take-up drum 2 adopts a snap-fit method, which does not require the use of bolts for tightening and limiting. Disassembly is also simple, only requiring the pulling of the T-shaped bracket 14 and the T-shaped side frame 17, which makes it convenient for users to quickly change the take-up drum 2.
[0025] Rubber blocks 19 are attached to the back of the blocking brackets 13 that are close to each other, and the side of the rubber blocks 19 that are close to each other is fixed to the side plate 4.
[0026] Specifically, the design of the rubber block 19 utilizes the elastic rebound of the rubber block 19 to provide a continuous counter-push force to the blocking frame 13, so as to make the T-shaped bracket 14 and the T-shaped side frame 17 more securely engaged, and avoid easy displacement affecting the positioning stability of the winding drum 2.
[0027] Electric push rods 7 are fixed on both sides of the top back of the back frame 3, and the piston rods of the electric push rods 7 are fixed on the corresponding side plates 4.
[0028] Specifically, the design of the electric push rod 7 allows for changes in the position of the side plate 4, facilitating precise adjustment of the side plate 4's position according to the size of the winding drum 2, thus improving the overall applicability of the device.
[0029] The back of the top and bottom of the push block 12 is inclined inward, and the inner sides of the T-shaped side frames 17 that are close to each other are chamfered.
[0030] Specifically, the shape of the push block 12 is defined so that the push block 12 and the fixing groove 11 can be stable and fast, which improves the assembly efficiency. The chamfer design allows the T-shaped side frame 17 to move outward stably when it contacts the side plate 4 when the blocking frame 13 swings and engages with the side plate 4, thus avoiding obstructing the normal swinging and engaging of the blocking frame 13.
[0031] Each set of side plates 4 is horizontally inserted with a square rod 6, and the two ends of the square rod 6 are fixed to both sides of the inner cavity of the sliding through groove 5.
[0032] Specifically, the design of the square rod 6 is to limit the direction of movement of the side plate 4, prevent one end of the side plate 4 from disengaging from the sliding groove 5, and improve the stability of the side plate 4 when it moves.
[0033] Multiple sets of docking screw holes 9 are evenly provided on the side of the side plate 4 that are far apart from each other, and docking grooves 10 are provided on both sides of the winding drum 2.
[0034] Specifically, the design of the connecting screw hole 9 allows for quick fixation of the mounting frame of the external motor. The mounting frame is telescopic and automatically positioned so that the output shaft end of the external motor can be stably inserted into the connecting groove 10, facilitating subsequent rotation of the winding drum 2.
[0035] Each side panel 4 is fixed with a reinforcing seat 8 whose back is attached to the back frame 3.
[0036] Specifically, the design of the reinforcing seat 8 not only improves the stability of the side plate 4 when it moves, but also improves the overall strength of the side plate 4, preventing the side plate 4 from easily breaking or tilting, and avoiding affecting the normal docking with the winding drum 2.
[0037] The specific usage process is as follows: The user first activates the electric push rod 7 via the controller, which moves the side plate 4 inward to a suitable position according to the size of the take-up drum 2. At this time, the blocking frame 13 is in an outward swing state. The user then engages the push blocks 12 at both ends of the take-up drum 2 with the fixing grooves 11 until the push blocks 12 are fully inserted into the fixing grooves 11. At this time, the user swings the blocking frame 13, and the T-shaped bracket 14 will first contact the side plate 4. Subsequently, the T-shaped side frame 17 will contact the side plate 4. As the blocking frame 13 continues to swing, the T-shaped bracket 14 and the T-shaped side frame 17 will move outward and stretch the first spring 15 and the second spring 18 until the blocking frame 13 is engaged on the side plate 4, and its bent end blocks and limits the push block 12. At this time, the T-shaped side frame 13 is engaged with the side plate 4. The bracket 14 and T-shaped side frame 17 will move to the preset insertion port and preset square hole respectively. At this time, the elastic rebound of the first spring 15 and the second spring 18 can drive the T-shaped bracket 14 and T-shaped side frame 17 to be inserted into the preset insertion port and preset square hole respectively, thereby achieving double positioning of the blocking frame 13 and the push block 12, quickly fixing the push block 12 to the side plate 4, thus quickly limiting the winding drum 2 to the side plate 4. The mounting frame of the external motor is freely telescopic and has a positioning structure. The mounting frame can be pre-fixed to the side of one set of side plates 4 through the docking screw holes 9, which facilitates the quick docking of the external motor with the winding drum 2. The overall assembly process of the winding drum 2 adopts a snap-fit type, without... The device requires bolts for securing the winding drum 2, and disassembly is equally simple, requiring only the pulling of the T-shaped bracket 14 and the T-shaped side frame 17, facilitating quick rewinding of the winding drum 2. This invention utilizes a multi-directional positioning assembly, with the locking mechanism of the fixing groove 11 and the push block 12, to initially position the winding drum 2. The design of the blocking frame 13, T-shaped bracket 14, first spring 15, extension bracket 16, T-shaped side frame 17, and second spring 18 forms a double-locking structure for the push block 12, quickly fixing it to the side plate 4. This quickly limits the winding drum 2 to the side plate 4, facilitating subsequent quick connection of the external motor with the winding drum 2. Furthermore, the mounting frame for the external motor is freely extendable and features a positioning structure, allowing for direct... Fixed to the side of one set of side plates 4, it facilitates quick docking with the take-up drum 2. The overall assembly process of the take-up drum 2 adopts a snap-fit method, which does not require the use of bolts for tightening and positioning. Disassembly is also simple, only requiring the pulling of the T-shaped bracket 14 and the T-shaped side frame 17, which makes it convenient for users to quickly change the take-up drum 2. The design of the rubber block 19 utilizes the elastic rebound of the rubber block 19 to provide a continuous counter-push force to the blocking frame 13, so as to make the T-shaped bracket 14 and the T-shaped side frame 17 more securely engaged, avoiding easy displacement that would affect the positioning stability of the take-up drum 2. The design of the electric push rod 7 can change the position of the side plate 4, which is convenient for precise adjustment of the position of the side plate 4 according to the size of the take-up drum 2, improving the overall applicability of the device.The defined shape of the push block 12 allows for stable and rapid engagement with the fixing groove 11, improving assembly efficiency. The chamfered design ensures that when the blocking frame 13 swings and engages with the side plate 4, the T-shaped side frame 17 can stably move outward upon contact with the side plate 4, preventing obstruction of the normal swinging and engagement of the blocking frame 13. The square rod 6 limits the direction of movement of the side plate 4, preventing one end of the side plate 4 from disengaging from the sliding groove 5, thus improving the stability of the side plate 4 during movement. The design of the connecting screw hole 9 allows for quick fixing of the external motor mounting frame, which is telescopic and automatically positioned, ensuring stable engagement of the external motor's output shaft with the connecting groove 10 for subsequent rotation of the winding drum 2. The design of the reinforcing seat 8 not only improves the stability of the side plate 4 during movement but also enhances its overall strength, preventing breakage or tilting and ensuring proper engagement with the winding drum 2.
[0038] In summary, this easy-to-change paper winding device employs a multi-directional positioning component and a double-locking structure. The push block can be quickly fixed to the side plate, thereby quickly limiting the winding drum to the side plate. This facilitates rapid docking of the external motor with the winding drum. The external motor mounting frame is freely retractable and features a positioning structure, allowing direct fixing to the side of one set of side plates for easy docking with the winding drum. The overall assembly of the winding drum uses a snap-fit method, eliminating the need for bolt tightening. Disassembly is equally simple, requiring only the pulling of the T-shaped bracket and T-shaped side frame, enabling users to quickly change the winding drum.
