Description

Technical Field

[0001] The invention relates to the technical field of feeding equipment, and in particular to a stable dual-transmission system. Background Art

[0002] Medical gauze is generally in the shape of a square handkerchief, and is generally made of thin gauze folded and sewn in multiple layers. In order to facilitate hanging, a cloth carrying strap is usually inserted when folding. In order to improve the sewing efficiency of medical gauze, an automatic production line for medical gauze has been introduced, which includes a reeling mechanism, a cutting mechanism, a carrying strap mechanism, a gauze folding mechanism, a sewing mechanism and a discharging mechanism from the input end to the output end. Each mechanism is connected by a conveyor belt, so that the material (thin gauze) can be finally processed into a finished medical gauze product after being unwound by the reeling mechanism and output from the discharging mechanism.

[0003] However, in the process of conveying gauze by the existing gauze feeding mechanism, when the feeding end and the discharging end of the feeding conveyor belt along the horizontal plane are far apart, and the feeding conveyor belt is made of flexible material, the feeding conveyor belt is prone to lag and the feeding end and the discharging end are out of sync after working for a long time, resulting in inconsistent gauze speeds in the process of conveying multiple pieces of gauze by the feeding mechanism, which in turn causes poor production phenomena such as reduced gauze processing quality and unsmooth operation of the feeding mechanism. Summary of the invention

[0004] The purpose of the present invention is to provide a stable dual-transmission system, which has the advantage of effectively reducing the probability of asynchronous operation of the overall feed conveyor belt caused by loosening of the feed conveyor belt, facilitating improving the consistency, stability, integrity and reliability of the operation process of the feed conveyor belt, thereby effectively improving the processing quality of the gauze.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: a stable dual-transmission system, including a frame, a feeding mechanism for feeding gauze is provided on the frame, the feeding mechanism includes a feeding conveyor belt for placing gauze, a roller assembly arranged on the frame and a power mechanism for driving the roller assembly, characterized in that the roller assembly includes a second turning roller and a third turning roller symmetrically arranged relative to the power mechanism, and a first guide wheel and a second guide wheel symmetrically arranged relative to the power mechanism; the feeding conveyor belt is successively wound around the first guide wheel, the second turning roller, the third turning roller and the second guide wheel to form a circulating loop, and a feeding reference plane for feeding gauze is formed between the first guide wheel and the second guide wheel; the power mechanism includes a movable end that can rotate relative to the frame, and the movable end includes at least two driving wheels that are linked to each other; any driving wheel is drivingly connected to the second turning roller, and the other driving wheel is drivingly connected to the third turning roller.

[0006] By adopting the above technical scheme, the feed conveyor belt is turned back and wound on the first turning roller after passing through the second turning roller, and is first wound on the fourth turning roller and then turned back and wound on the third turning roller. Through multiple turning rollers, the feed conveyor belt can be in a tensioned state, so as to reduce the probability of the overall operation of the feed conveyor belt being asynchronous due to the loosening of the feed conveyor belt, so as to reduce the probability of the processing quality decline caused by the dislocation of the gauze, thereby effectively improving the working efficiency of the feed conveyor belt in transmitting gauze. Secondly, by connecting the movable end of the power mechanism to the first turning roller and the third turning roller at both ends at the same time, the feed end and the discharge end of the feed conveyor belt can both have power control with the same movement direction, so as to improve the consistency, stability, integrity and reliability of the operation process of the feed conveyor belt, thereby improving the stability of the gauze feeding process, and effectively reducing the probability of the gauze processing quality decline caused by the inconsistency of the operation process of the feed conveyor belt.

[0007] A further configuration of the present invention is that the frame is provided with at least one pressing mechanism for pressing the gauze, the pressing mechanism includes a pressing wheel located above the feed reference plane and capable of contacting the surface of the gauze, and a linear drive mechanism fixed on the frame, the pressing wheel being arranged on the movable end of the linear drive mechanism.

[0008] By adopting the above technical solution, the pressing mechanism can press the gauze and place it on the feeding conveyor belt, so as to improve the consistency between the gauze and the feeding conveyor belt during movement. Moreover, after the pressing mechanism is set on the linear drive mechanism, the pressure of the pressing wheel pressing the gauze can be adjusted by adjusting the distance between the movable end of the linear drive mechanism and the feeding conveyor belt, so as to adapt to the installation stability required by the gauze during processing or cutting and the convenience of disassembly when moving to the next process.

[0017] By adopting the above technical scheme, the transmission method of gear meshing between the two adjacent first turning rollers and the second turning roller, and the third turning roller and the fourth turning roller can effectively improve the consistency and continuity of the roller assembly in the process of driving the feed conveyor belt to move, thereby improving the consistency of the gauze following the movement of the feed conveyor belt, thereby effectively improving the gauze processing quality.

[0019] By adopting the above technical solution, the adjacently arranged first turning roller and second turning roller, third turning roller and fourth turning roller can further improve the consistency of the winding of the feed conveyor belt, thereby improving the consistency, stability and reliability of the gauze running on the feed conveyor belt.

[0020] According to a further configuration of the present invention, the first guide wheel and the second guide wheel have square cross-sections.

[0021] By adopting the above technical solution, the first guide wheel and the second guide wheel with a square cross-section can further reduce the probability of the feed conveyor belt becoming loose at both ends along the feeding direction, so as to improve the consistency and stability of the overall movement of the feed conveyor belt.

[0035] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0036] Embodiment: A stable dual transmission system, such as Figures 1 to 4 As shown, it includes a frame 1, on which a feeding mechanism 2 for feeding gauze 19 is provided, and the feeding mechanism 2 includes a feeding conveyor belt 3 for placing the gauze 19, a roller assembly 4 arranged on the frame 1, and a power mechanism 5 for driving the roller assembly 4. On the frame 1, along the feeding direction of the feeding conveyor belt 3, a thread cutting mechanism 17 and an automatic sewing machine 18 for cutting the gauze 19 are sequentially provided, and the thread cutting mechanism 17 and the automatic sewing machine are both commonly used processing equipment in the field. By cooperating with the feeding mechanism 2 with high consistency in the running process, the processing quality of the gauze 19 processing or cutting can be effectively improved. In this embodiment, the feeding conveyor belt 3 is a transmission belt commonly used in the technical field, and the first turning roller 7, the second turning roller 8, the third turning roller 9 and the fourth turning roller 10 are all commonly used transmission rollers in the technical field, but are not limited to this embodiment.

[0037] like Figures 1 to 4As shown, the feed conveyor belt 3 is annularly wound on the roller assembly 4, and the roller assembly 4 includes a second turning roller 8 and a third turning roller 9 symmetrically arranged relative to the power mechanism 5, and a first guide wheel 6 and a second guide wheel 11 symmetrically arranged relative to the power mechanism 5; the feed conveyor belt (3) is sequentially wound around the first guide wheel 6, the second turning roller 8, the third turning roller 9 and the second guide wheel 11 to form a circulating loop, and a feeding reference surface 20 for feeding the gauze 19 is formed between the first guide wheel 6 and the second guide wheel 11; the power mechanism 5 includes a movable end 52 that can rotate relative to the frame 1, and the movable end 52 includes at least two mutually linked driving wheels 521; any one of the driving wheels 521 is drivingly connected to the second turning roller 8, and the other driving wheel 521 is drivingly connected to the third turning roller 9.

The feed conveyor belt 3 is wound around the first guide wheel 6, then around the second turning roller 8, and then around the first turning roller 7, then around the fourth turning roller 10, and then around the third turning roller 9.

[0038] The first guide wheel 6 and the second guide wheel 11 are both metal components with two rollers located on the same horizontal line. The square cross-section of the first guide wheel 6 and the second guide wheel 11 means that the route of the feed conveyor belt 3 wound around the above two is square, which can further reduce the probability of the feed conveyor belt 3 becoming loose at both ends along the feeding direction, so as to improve the consistency and stability of the overall movement of the feed conveyor belt 3.

[0039] The first turning roller 7 is arranged adjacent to the second turning roller 8, and the third turning roller 9 is arranged adjacent to the fourth turning roller 10.

The axial symmetric arrangement of the first turning roller 7 and the third turning roller 9, the second turning roller 8 and the fourth turning roller 10 relative to the power mechanism 5 can enable the feed conveyor belt 3 to obtain equivalent power traction at both ends of the first guide wheel 6 and the second guide wheel 11, so as to improve the consistency, stability and reliability of the overall movement of the feed conveyor belt 3.

Through the gear meshing transmission mode, the consistency and continuity of the roller assembly 4 in the process of driving the feed conveyor belt 3 to move can be effectively improved, thereby improving the consistency of the gauze 19 following the feed conveyor belt 3 to move, thereby effectively improving the processing quality of the gauze 19.

[0041] The power mechanism 5 includes a first motor 53 for providing power, and the first motor 53 is connected to the first turning roller 7 and the third turning roller 9 through a transmission belt 54.

The first motor 53 can provide stable and continuous power output for both ends of the roller assembly 4 at the same time, so as to eliminate the undesirable production phenomenon of inconsistent movement of the gauze 19 caused by the looseness of the feed conveyor belt 3.

[0042] The frame 1 is provided with a pressing mechanism 12 for pressing the gauze 19. The pressing mechanism 12 includes a pressing wheel 121 located above the feed reference surface 20 and capable of contacting the surface of the gauze 19 and a linear drive mechanism 122 fixed on the frame 1. In the present embodiment, the linear drive mechanism 122 is a linear cylinder, but is not limited to a linear cylinder, and can realize linear motion. The pressing wheel 121 is arranged on the movable end 52 of the linear drive mechanism 122. The pressing mechanism 12 can make the gauze 19 pressed and placed on the feed conveyor belt 3, so as to improve the consistency of the gauze 19 and the feed conveyor belt 3 during the movement. Moreover, after the pressing mechanism 12 is arranged on the linear drive mechanism 122, the pressure of the pressing wheel 121 pressing the gauze 19 can be adjusted by adjusting the spacing between the movable end 52 on the linear drive mechanism 122 and the feed conveyor belt 3, so as to adapt the gauze 19 to the required installation stability during the processing or cutting process and the convenience of disassembly when moving to the next process. The pressing mechanism 12 includes four pressing rollers 123 arranged in an annular manner on the frame 1, and a pressing conveyor belt 124 that can press the cloth on the feed conveyor belt 3 is wound around the adjacent pressing rollers 123.
