Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of filter paper processing, and more specifically, to a paper-pulling structure for filter paper processing. Background Technology

[0002] In the filter paper processing and production field, filter paper, as an important industrial consumable, is widely used in industries such as medical, food, and chemical. Its processing quality directly affects the subsequent performance. The process from unrolling the entire roll of filter paper to the subsequent cutting step is crucial. The entire roll of filter paper needs to be smoothly and accurately fed to the cutting equipment to ensure uniform cutting dimensions and neat edges. However, existing filter paper processing feeding structures have significant drawbacks and cannot meet the demands of high-efficiency production.

[0003] Currently, most filter paper processing equipment uses fixed supports or simple guide roller structures for feeding whole rolls of filter paper. This method has two problems: First, during the unrolling process, the lack of an effective paper-pulling and tension control structure easily leads to filter paper misalignment, wrinkles, or uneven tension, resulting in inaccurate positioning when feeding to subsequent cutting processes, affecting cutting accuracy, and even causing filter paper waste. Second, existing structures require manual disassembly of the fixing device when changing filter paper rolls or performing equipment maintenance, which is cumbersome and time-consuming. For example, traditional fixed supports usually use bolts or clips to fix the filter paper rolls, requiring machine shutdown and individual operation each time, which not only increases labor costs but also leads to long equipment downtime and low production efficiency.

[0004] With the increasing automation in the filter paper processing industry, higher demands are placed on the stability and convenience of the feeding structure. How to achieve smooth feeding of the entire roll of filter paper to the cutting process during processing, while simplifying the assembly and disassembly process, has become an urgent problem to be solved. Existing technical solutions cannot effectively balance feeding accuracy and assembly / disassembly efficiency, leading to frequent feeding jams and large cutting errors during production, severely restricting the production capacity and quality of filter paper processing.

[0005] Therefore, developing a paper feeding structure that can efficiently feed materials and is easy to assemble and disassemble is of great practical significance. It can significantly improve the automation level and production efficiency of filter paper processing and meet the high-quality and high-efficiency requirements of modern industry for filter paper processing. Utility Model Content

[0006] To overcome the above-mentioned defects, the embodiments of this disclosure provide a paper-pulling structure for filter paper processing, which solves the technical problem that the lack of an effective paper-pulling and tension control structure in the prior art makes it easy for filter paper to shift, wrinkle or uneven tension to occur, resulting in inaccurate positioning when feeding to the subsequent cutting process.

[0007] According to one aspect, at least one embodiment of this disclosure provides a paper-feeding structure for filter paper processing, comprising:

[0008] A base frame and a pair of side frames, the side frames being disposed on both sides of the base frame;

[0009] A support release assembly is provided on the side frame and the base frame;

[0010] A transverse frame and a guiding conveying assembly, wherein the transverse frame is disposed outside the base frame and the guiding conveying assembly is disposed on the transverse frame;

[0011] A retractable connection assembly is disposed between the base frame and the transverse frame;

[0012] The support release assembly includes a pair of side plates, which are rotatably connected to the outer end of the side frame via pins. Support blocks are rotatably connected inside each side plate. A drive motor is provided on the side surface of one side plate, and the output end of the drive motor is connected to the support block. A telescopic cylinder is rotatably connected between the side frame and the side plate via pins.

[0013] As a further technical solution, a movable cavity is provided in the base frame, and the side frames are respectively movably fitted to both ends of the movable cavity. An adjusting screw is rotatably connected in the movable cavity, and both ends of the adjusting screw are connected to the side frame through threaded engagement.

[0014] As a further technical solution, a second motor is provided at the bottom of the base frame, a drive gear is provided at the output end of the second motor, and a transmission gear is provided on the adjusting screw, with the drive gear meshing with the transmission gear.

[0015] As a further technical solution, the guiding and conveying assembly includes a pair of horizontal shafts, both of which are rotatably connected within the transverse frame. Each horizontal shaft has a synchronous gear at one end, and the synchronous gears mesh with each other. One of the horizontal shafts is rotated by a motor.

[0016] As a further technical solution, a number of conveying wheels are installed on the horizontal axis, and connecting frames are provided at both ends of the horizontal frame. The connecting frames are rotatably connected to each other by pins and guide covers.

[0017] As a further technical solution, the retractable connection assembly includes a pair of connecting rods, each of which is fixed to the bottom of the transverse frame. One end of each connecting rod is rotatably connected to the base frame via a pin. A second cylinder is rotatably connected between the pair of connecting rods and the base frame via a pin.

[0018] As a further technical solution, the support blocks are all conical structures, and the surface of the support blocks is an anti-slip surface.

[0019] As a further technical solution, the side end face of the guide cover is an arc-shaped structure surface, and the side end face of the guide cover slides and fits against the surface of the transverse frame. The guide cover can be rotated upward and downward by 60° through the pin shaft rotation connection.

[0020] The beneficial effects of the embodiments disclosed herein are as follows:

[0021] 1. The beneficial effects of the support release assembly in this disclosure are that the side plate can be flexibly adjusted in angle through the pin and telescopic cylinder, and the support block can be rotated by the drive motor to achieve stable release and tension control of the whole roll of filter paper, avoiding filter paper deviation, wrinkles or uneven tension. The adjusting screw in the base frame and the second motor can automatically adjust the side frame spacing to adapt to filter paper shafts of different lengths. There is no need for frequent manual disassembly and fixing of the device, which greatly reduces disassembly and assembly time and improves production efficiency. The conical anti-slip support block can stably support the filter paper shaft, ensuring a smooth unwinding process and providing reliable front-end support for subsequent conveying and cutting processes.

[0022] 2. The beneficial effects of the guiding and conveying assembly in this disclosure are that a pair of horizontal shafts rotate synchronously through synchronous gears, ensuring that the conveying wheels on both sides run in unison, so that the filter paper is subjected to uniform force during the conveying process, reducing the problem of deviation or wrinkling caused by asynchronous conveying. The multiple conveying wheels increase the contact area with the filter paper, providing stable conveying power. The guide covers at both ends of the transverse frame can rotate 60°, and their arc-shaped structural surfaces slide against the transverse frame, which can flexibly adjust the guiding angle according to the filter paper conveying situation, effectively guiding the filter paper to maintain the correct direction, avoiding deviation, ensuring that the filter paper is conveyed flat and accurately to the cutting process, and improving the precision and quality of filter paper processing.

[0036] like Figures 1-5 As shown, it illustrates a paper-feeding structure for filter paper processing according to an embodiment of the present disclosure, comprising:

[0037] A base frame 1 and a pair of side frames 2, the side frames 2 being disposed on both sides of the base frame 1;

[0038] Support release assembly 4 is provided on the side frame 2 and the base frame 1;

[0039] A transverse frame 3 and a guide conveying assembly 5 are provided, wherein the transverse frame 3 is disposed outside the base frame 1 and the guide conveying assembly 5 is disposed on the transverse frame 3;

[0040] A retractable connecting component 6 is disposed between the base frame 1 and the transverse frame 3;

[0041] The support release assembly 4 includes a pair of side plates 4-1, which are rotatably connected to the outer end of the side frame 2 via pins. Support blocks 4-2 are rotatably connected inside each side plate 4-1. A drive motor 4-3 is provided on the side surface of one side plate 4-1, and the output end of the drive motor 4-3 is connected to the support block 4-2. A telescopic cylinder 4-4 is rotatably connected between the side frame 2 and the side plate 4-1 via pins. A movable cavity 4-5 is provided inside the base frame 1, and the side frame 2 is movably fitted to both ends of the movable cavity 4-5. An adjusting screw 4-6 is rotatably connected inside the movable cavity 4-5, and both ends of the adjusting screw 4-6 are threadedly connected to the side frame 2. A second motor 4-7 is provided at the bottom of the base frame 1, and a drive gear 4-8 is provided at the output end of the second motor 4-7. A transmission gear 4-9 is provided on the adjusting screw 4-6, and the drive gear 4-8 meshes with the transmission gear 4-9.

[0042] In some examples, during filter paper processing, to achieve stable support for the entire roll of filter paper shaft and flexibly adjust the support spacing according to the length of the filter paper shaft for smooth unwinding, a support and unwinding assembly 4 is designed. This assembly includes a pair of side plates 4-1 rotatably connected to the outer end of the side frame 2 via pins. The side plates 4-1 provide a mounting base for the support blocks 4-2, which are rotatably connected internally to directly support the filter paper shaft. A drive motor 4-3 is installed on the side surface of one side plate 4-1, with its output end connected to the support block 4-2, which can drive the support block 4-2 to rotate, thereby realizing the unwinding action of the filter paper shaft and ensuring that the filter paper can be unwound evenly and stably. A telescopic cylinder 4-4 is rotatably connected between the side frame 2 and the side plate 4-1 via pins, which can adjust... The tilt angle or support height of the side plate 4-1 allows for quick opening and closing for loading and unloading the filter paper shaft. The movable cavity 4-5 inside the base frame 1 is movably connected to the side frame 2 at both ends, forming a sliding support structure. The adjusting screw 4-6, rotatably connected inside the movable cavity 4-5, engages with the side frame 2 at both ends via threads. When the adjusting screw 4-6 rotates, it can drive the two side frames 2 to move closer or further apart synchronously, thereby precisely adjusting the support spacing according to the length of the filter paper shaft. The second motor 4-7 at the bottom of the base frame 1 has a drive gear 4-8 at its output end that meshes with the transmission gear 4-9 on the adjusting screw 4-6. When the second motor 4-7 starts, it drives the adjusting screw 4-6 to rotate through gear transmission, realizing the automatic adjustment of the spacing of the side frames 2 and improving operating efficiency.

[0043] like Figures 1-5As shown in the figure, the guide conveying assembly 5 in this embodiment includes a pair of horizontal shafts 5-1, both of which are rotatably connected within the transverse frame 3. Each of the horizontal shafts 5-1 is provided with a synchronous gear 5-2 at one end, and the synchronous gears 5-2 mesh with each other. One of the horizontal shafts 5-1 is controlled to rotate by a motor. Several conveying wheels 5-3 are installed on the horizontal shaft 5-1. Both ends of the transverse frame 3 are provided with connecting frames 5-4, and the connecting frames 5-4 are rotatably connected to the guide cover 5-5 by a pin.

[0044] In some examples, to improve the stability and flatness of the filter paper during dispensing and to prevent wrinkles or shifting, a guide conveying assembly 5 is designed. This assembly ensures the filter paper remains stable and flat during conveying, meeting the requirements of subsequent processing or use. The assembly includes a pair of horizontal shafts 5-1 rotatably connected within the transverse frame 3. Synchronous gears 5-2 at one end of each horizontal shaft 5-1 mesh with each other. When one horizontal shaft 5-1 rotates under motor control, the other horizontal shaft 5-1 rotates synchronously through the transmission of the synchronous gears 5-2, ensuring the smooth operation of the conveyor wheels 5-3 on both sides. The synchronous operation helps maintain the stability of filter paper conveying. Several conveying wheels 5-3 installed on the horizontal shaft 5-1 rotate together with the horizontal shaft 5-1, which plays a role in conveying the filter paper and smoothly conveying the filter paper forward. The connecting frames 5-4 set at both ends of the horizontal frame 3 are connected to the guide covers 5-5 by pins. The guide covers 5-5 can be adjusted in angle according to the conveying of the filter paper. It can guide the released filter paper, keep the filter paper in the correct direction during the conveying process, avoid the filter paper from deviating, and further improve the stability and flatness of the filter paper conveying.

[0045] like Figures 1-5 As shown in the figure, the retractable connection assembly 6 in this embodiment includes a pair of connecting rods 6-1. The connecting rods 6-1 are all fixed to the bottom of the transverse frame 3. One end of each connecting rod 6-1 is rotatably connected to the base frame 1 by a pin. A second cylinder 6-2 is rotatably connected between the pair of connecting rods 6-1 and the base frame 1 by a pin.

[0046] In some examples, to achieve easy mobility, a retractable connecting assembly 6 is designed. This assembly includes a pair of connecting rods 6-1 fixed to the bottom of the transverse frame 3. One end of each rod is rotatably connected to the base frame 1 via a pin, allowing the transverse frame 3 to rotate around the pin as a fulcrum, thus achieving the retractable action. The second cylinder 6-2, which is rotatably connected to the base frame 1 via a pin, is the core driving component for controlling the retractable action of the transverse frame 3. When the second cylinder 6-2 extends, its thrust drives the transverse frame 3 to expand outward around the pin axis through the connecting rods 6-1, thus achieving the unfolding action. When the second cylinder 6-2 retracts, it can be retracted, thus reducing the overall size for easy movement.

[0047] For example, such as Figure 1 As shown, the support blocks 4-2 are all conical structures, and the surface of the support blocks 4-2 is an anti-slip surface.

[0048] In some examples, the conical structure facilitates accurate insertion into both ends of the filter paper shaft when the support moves along the arc.

[0049] For example, such as Figure 5 As shown, the side end face of the guide cover 5-5 is an arc-shaped structure surface. The side end face of the guide cover 5-5 is slidably attached to the surface of the transverse frame 3. The guide cover 5-5 can be rotated upward and downward by 60° through the pin shaft rotatable connection.

[0050] In some examples, the curved structure allows the guide cover 5-5 to fit against the surface of the transverse frame 3 during rotation, preventing the filter paper from getting stuck.

[0051] In actual use: When in use, according to the length of the filter paper shaft, start the second motor 4-7 at the bottom of the base frame 1. Through the meshing of the drive gear 4-8 and the transmission gear 4-9, the adjusting screw 4-6 is rotated, so that the side frame 2 moves synchronously in the movable cavity 4-5 to adjust the spacing. After adjustment, start the telescopic cylinder 4-4 to open the two support blocks 4-2. Put the whole roll of filter paper shaft on the two support blocks 4-2. The support blocks 4-2 have a conical anti-slip structure and can be stably inserted into both ends of the filter paper shaft when resetting. Then start the drive motor 4-3 to drive the support blocks 4-2 to rotate and release the filter paper. The released filter paper passes through the guide conveying assembly 5 on the transverse frame 3. The conveying wheel 5-3 on the transverse shaft 5-1 rotates synchronously to convey the filter paper under the cooperation of the motor drive and the synchronous gear 5-2. The guide cover 5-5 can rotate to adjust the angle to guide the filter paper and ensure that it is smoothly conveyed to the subsequent cutting process. When moving, the second cylinder 6-2 retracts to drive the connecting rod 6-1 to retract the transverse frame 3 and then move through the pulley at the bottom.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
