[0002] In medical supplies, high-speed folding machines are used to produce gauze sheets. When the high-speed folding machine is running at high speed, its transmission relationship is very complicated, and different driving methods need to be adopted for different components. Among them, the radial folding line of the high-speed folding machine is involved. It is a system that folds the gauze sheet axially to form a gauze strip, and then folds the gauze strip radially. This system currently uses an assembly line layout for each folding part, with many auxiliary equipment, long lines, and many drive devices. It not only takes up a lot of space, but also has many drive devices, high power, and loud noise when working. Summary of the invention

[0005] The power transmission system includes a main gear and an intercalation eccentric disk respectively connected to the two output ends of the servo commutator, transition gears are matched on both sides of the main gear, the edge pressing gear and the transfer gear are respectively meshed with the two transition gears, and the hook folding gear is meshed with the transfer gear; the power transmission system is arranged on one side or both sides of the intercalation mechanism, the holding mechanism and the transfer mechanism.

[0006] The hook-folding pushing mechanism comprises a hook-folding eccentric disk and a ball seat connected by a hook-folding connecting rod, a cross arm connected to the ball seat, the ball seat and the optical axis are slidably matched, the hook-folding plate is connected to the cross arm, and the hook-folding eccentric disk is connected to the shaft end of the hook-folding gear of the power transmission system.

[0007] A push plate is also connected to the cross arm. The push plate is located in the storage groove and is slidably engaged therewith. A guide plate is provided on one side of the storage groove. The hook folding plate slides along the longitudinal fold seam between the guide plate and the wall plate of the storage groove. The horizontal fold seam is perpendicular to and intersects the longitudinal fold seam and penetrates through the guide plate and the storage groove.

[0008] The inserting and folding mechanism includes a slider engaged with a slide rail, and an inserting and folding plate and an inserting and folding connecting rod connected to the slider. The other end of the inserting and folding connecting rod is connected to the inserting and folding eccentric disk of the power transmission system.

[0009] The pressing mechanism includes a support plate connected by a rolling bearing engaged with an eccentric groove cam. The two ends on the same side of the two sliding rods are respectively slidably engaged with and fixedly connected to the support plate. The linear bearing seat is respectively slidably engaged with and fixedly connected to the two sliding rods. The buffer is connected to the linear bearing seat.

[0010] The transfer mechanism includes adsorption petals connected by a hollow shaft. The adsorption holes provided on the end face of the adsorption petals are communicated with the hollow shaft. The adsorption petals are provided with accommodation grooves along the radial direction. Both ends of the hollow shaft are connected to transfer gears.

[0011] The hook folding plate is a right-angled bent flat plate. The inner edge along the vertical side is a toothed edge. A plurality of notches are distributed in the toothed edge. The horizontal section is connected to the cross arm.

[0012] The storage groove is a rectangular groove with openings at both ends and one side. A toothed plate is provided in the rectangular groove on one side of the horizontal fold seam.

[0013] The power transmission method with noise reduction in the high-speed state as described above includes the following steps:

[0014] S1. Power transmission: One output end of the servo commutator drives the main gear to drive the intermediate gear to rotate. The intermediate gear drives the edge pressing gear and the transfer gear to rotate; The other output end of the servo commutator drives the inserting and folding eccentric disk to rotate; The transfer gear drives the hook folding gear to rotate;

[0015] In this step, when the power transmission system is on both sides of the inserting and folding mechanism, the pressing mechanism and the transfer mechanism, the hook folding gear on one side is cancelled;

[0016] S2. Linkage: The hook folding and pushing mechanism, the inserting and folding mechanism, the pressing mechanism and the transfer mechanism are synchronously linked;

[0017] S2-1. The hollow shaft of the transfer mechanism drives the adsorption petals to rotate, and the gauze strips adsorbed on the adsorption petals move synchronously therewith;

[0018] S2-2. The hook folding eccentric disk of the hook folding and pushing mechanism drives the hook folding connecting rod to drive the cross arm and the ball seat to move linearly back and forth along the optical axis. The hook folding plate enters the accommodation groove of the adsorption petals with the movement of the cross arm to hook the gauze strip and withdraw; When withdrawing, the gauze strip is pulled into the longitudinal fold seam to perform the first folding on the gauze strip;

[0019] In this step, the push plate slides along the receiving groove driven by the cross arm, pushing the folded gauze strip backward to reserve space for the next insertion and folding.

[0020] S2-3. The eccentric groove cam of the pressing mechanism drives the rolling bearing to move horizontally. The rolling bearing drives the support plate and the sliding rod to move horizontally. The linear bearing seat on the sliding rod drives the buffer to move to one side. The buffer passes through the guiding plate to press the end of the first-folded gauze strip.

[0021] S2-4. The hook folding plate withdraws from the longitudinal fold. The insertion link of the insertion and folding mechanism drives the slider to slide along the slide rail. When the insertion folding plate slides with the slider, it passes through the horizontal fold to perform the second folding of the gauze strip. At the same time, the buffer resets and releases the pressing on the gauze strip. In this step, the folded gauze strip enters the receiving groove.

[0022] In S2-2, the push plate slides along the receiving groove driven by the cross arm, pushing the folded gauze strip backward to reserve insertion space for the next insertion folding plate.

[0023] The main beneficial effects of the present invention are as follows:

[0024] One or two sets of power transmission systems are used to cooperate and connect with each component mechanism, with a compact structure, less occupied space, and at the same time, they are linked, enabling multiple actions to be synchronously coupled. The whole machine has a small power, energy-saving, and low noise during synchronous operation.

[0025] Through linkage, the gauze strip is successively transferred, first folded, second folded, and stored. Its speed is controllable, and during control, only the speed of the servo commutator needs to be singly controlled to control the entire production speed, which can be adjusted from low speed to high speed and is not affected.

Detailed implementation mode

[0038] As Figures 1 to 10 shown in, a power transmission coupling structure with noise reduction in a high-speed state, which includes a power transmission system 1, a hook folding and pushing mechanism 2, an inserting and folding mechanism 3, a pressing mechanism 4 and a transfer mechanism 5; the hook folding and pushing mechanism 2, the inserting and folding mechanism 3, the pressing mechanism 4 and the transfer mechanism 5 are all directly connected to the power transmission system 1 and are synchronously linked; during linkage, the hook folding plate 26 of the hook folding and pushing mechanism 2 longitudinally expands and contracts, the inserting and folding plate 33 of the inserting and folding mechanism 3 horizontally expands and contracts, the buffer 46 of the pressing mechanism 4 horizontally and laterally slides through the guiding plate 29 of the hook folding and pushing mechanism 2, and the hollow shaft 51 of the transfer mechanism 5 drives the adsorption flap 52 to rotate and cooperate with the hook folding plate 26. When in use, the power transmission system 1 drives each mechanism to be synchronously linked, couples the actions of the transfer mechanism 5 and the inserting and folding mechanism 3 to complete the first folding, and couples the hook folding and pushing mechanism 2, the inserting and folding mechanism 3 and the pressing mechanism 4 to complete the second folding. The structure is compact, occupies a small space, has few driving devices and low energy consumption, and has low noise during simultaneous operation.

[0039] In a preferred embodiment, the power transmission system 1 includes a main gear 12 and an inserting and folding eccentric disc 13 respectively connected to two output ends of a servo commutator 11. Transition gears 14 are engaged with both sides of the main gear 12. A hemming gear 15 and a transfer gear 16 are respectively engaged with the two transition gears 14, and a folding gear 17 is engaged with the transfer gear 16. The power transmission system 1 is disposed on one side or both sides of the inserting and folding mechanism 3, the pressing mechanism 4, and the transfer mechanism 5. During use, the power transmission system 1 is mainly used for power transmission, reasonably distributing the two outputs of the servo commutator 11 to each mechanism, enabling each mechanism to be integrated together and actively controlled by it, thereby simplifying the overall machine control and allowing arbitrary adjustment between low speed and high speed.

[0040] Preferably, when there are two sets of power transmission systems 1, the folding gear 17 on one side can be cancelled, and only one folding gear 17 is used to drive the folding and pushing mechanism 2, which not only saves energy but also keeps the actions of the two folding and pushing mechanisms 2 synchronized.

[0041] In a preferred embodiment, the folding and pushing mechanism 2 includes a folding eccentric disc 22 and a ball seat 23 connected by a folding link 21. A cross arm 24 is connected to the ball seat 23. The ball seat 23 is slidably engaged with a light shaft 25. A folding plate 26 is connected to the cross arm 24. The folding eccentric disc 22 is connected to the shaft end of the folding gear 17 of the power transmission system 1. During use, the folding and pushing mechanism 2 is driven by the folding eccentric disc 22 connected by the folding gear 17. Due to the eccentric connection structure of the folding link 21 and the folding eccentric disc 22, the ball seat 23 and the cross arm 24 are driven to move longitudinally back and forth, so that the folding plate 26 extends into the receiving groove 54 of the adsorption flap 52 to hook out the gauze strip and fold it when retracting.

[0042] In a preferred embodiment, a push plate 27 is further connected to the cross arm 24. The push plate 27 is slidably engaged with a receiving groove 28. A guiding plate 29 is provided on one side of the receiving groove 28. The folding plate 26 slides along a longitudinal fold seam between the guiding plate 29 and the wall plate of the receiving groove 28. The horizontal fold seam is perpendicular to and intersects the longitudinal fold seam and penetrates through the guiding plate 29 and the receiving groove 28. During use, the push plate 27 moves synchronously with the cross arm 24 and is used to push the folded gauze strip into the receiving groove 28 during retraction. The wall plate on one side of the receiving groove 28 and the guiding plate 29 form a longitudinal fold seam, so that the folding plate 26 folds the gauze strip for the first time in the longitudinal fold seam during the process of hooking and retracting the gauze strip. The horizontal fold seam passes through the receiving groove 28 and the guiding plate 29 and intersects the longitudinal fold seam perpendicularly, thus forming a second folding channel.

[0043] In a preferred embodiment, the folding and inserting mechanism 3 includes a slider 32 cooperating with a slide rail 31, a folding and inserting plate 33 and a folding and inserting connecting rod 34 connected to the slider 32. The other end of the folding and inserting connecting rod 34 is connected to the folding and inserting eccentric disc 13 of the power transmission system 1. During installation, one end of the folding and inserting connecting rod 34 is eccentrically connected to the folding and inserting eccentric disc 13. During use, the folding and inserting mechanism 3 drives the folding and inserting eccentric disc 13 through the vertical output end of the servo commutator 11. The folding and inserting eccentric disc 13 drives the folding and inserting connecting rod 34 to drive the slider 32 to reciprocate along the slide rail 31. When the folding and inserting plate 33 moves with the slider 32, it performs a second fold on the gauze strip.

[0044] In a preferred embodiment, the pressing mechanism 4 includes a support plate 43 connected to a rolling bearing 42 cooperating with an eccentric groove cam 41. The two ends on the same side of the two slide rods 44 are respectively in sliding fit and fixedly connected with the support plate 43. A linear bearing seat 45 is respectively in sliding fit and fixedly connected with the two slide rods 44. A buffer 46 is connected to the linear bearing seat 45. During use, the rolling bearing 42 rolls in the eccentric groove of the eccentric groove cam 41. The eccentric groove cam 41 is connected to the edge pressing gear 15. The rotation of the edge pressing gear 15 drives the eccentric groove cam 41 to rotate. The eccentric groove cam 41 drives the rolling bearing 42 to drive the support plate 43 to move back and forth left and right. One of the two slide rods 44 drives the buffer 46 to move as the support plate 43 moves horizontally. The other slide rod 44 cooperates with the linear bearing seat 45 for limiting. The buffer 46 passes through the guide plate 29 to press the end of the folded gauze strip.

[0045] In a preferred embodiment, the transfer mechanism 5 includes an adsorption flap 52 connected to a hollow shaft 51. Adsorption holes 53 provided on the end face of the adsorption flap 52 communicate with the hollow shaft 51. The adsorption flap 52 is provided with a receiving groove 54 along the radial direction. Both ends of the hollow shaft 51 are connected to the transfer gear 16. During use, the hollow shaft 51 is communicated with a centrifugal fan, so that the adsorption holes 53 at the end of the adsorption flap 52 generate an adsorption force for adsorbing the gauze strip. The receiving groove 54 is used for receiving the hook folding plate 26.

[0046] In a preferred embodiment, the hook folding plate 26 is a right-angled bent flat plate. The inner edge along the vertical side is a toothed edge. A plurality of notches are distributed in the toothed edge. The horizontal section is connected to the cross arm 24. During use, the toothed edge of the hook folding plate 26 is used to hook the gauze strip to prevent the gauze strip from slipping along the vertical side of the hook folding plate 26 due to the adsorption force and rotational force of the adsorption flap 52 when the gauze strip is hooked out.

[0047] In a preferred embodiment, the storage groove 28 is a rectangular groove with openings at both ends and one side. A toothed plate is arranged in the rectangular groove on one side of the horizontal fold. During use, during the second fold, after the folding and inserting plate 33 inserts the gauze strip after the first fold into the horizontal fold, the folding and inserting plate 33 still needs to withdraw. During the withdrawal process, the teeth on the toothed plate are used to contact the gauze strip to prevent the folded gauze from being taken out of the horizontal fold by the folding and inserting plate 33 when it withdraws.

[0048] In a preferred solution, the power transmission method with noise reduction in the high-speed state as described above includes the following steps:

[0049] S1. Power transmission: One output end of the servo commutator 11 drives the main gear 12 to drive the transition gear 14 to rotate, and the transition gear 14 drives the edge pressing gear 15 and the transfer gear 16 to rotate; the other output end of the servo commutator 11 drives the inserting and folding eccentric disc 13 to rotate; the transfer gear 16 drives the hook folding gear 17 to rotate;

[0050] In this step, when the power transmission system 1 is located on both sides of the inserting and folding mechanism 3, the pressing mechanism 4 and the transfer mechanism 5, the hook folding gear 17 on one side is cancelled;

[0051] S2. Linkage: The hook folding and pushing mechanism 2, the inserting and folding mechanism 3, the pressing mechanism 4 and the transfer mechanism 5 are synchronously linked;

[0052] S2-1. The hollow shaft 51 of the transfer mechanism 5 drives the adsorption flap 52 to rotate, and the gauze strip adsorbed on the adsorption flap 52 moves synchronously with it;

[0053] S2-2. The hook folding eccentric disc 22 of the hook folding and pushing mechanism 2 drives the hook folding connecting rod 21 to drive the cross arm 24 and the ball seat 23 to move linearly back and forth along the optical axis 25, and the hook folding plate 26 enters the accommodation groove 54 of the adsorption flap 52 along with the cross arm 24 to hook the gauze strip and withdraw; when withdrawing, the gauze strip is pulled to enter the longitudinal fold to perform the first folding of the gauze strip;

[0054] In this step, the push plate 27 slides along the storage groove 28 driven by the cross arm 24, and pushes the folded gauze strip backward to reserve space for the next inserting and folding;

[0055] S2-3. The eccentric groove cam 41 of the pressing mechanism 4 drives the rolling bearing 42 to displace horizontally, the rolling bearing 42 drives the support plate 43 and the sliding rod 44 to move horizontally, and the linear bearing seat 45 located on the sliding rod 44 drives the buffer 46 to move to one side, and the buffer 46 passes through the guiding plate 29 to press the end of the first folding of the gauze strip;

[0056] S2-4. The hook folding plate 26 withdraws from the longitudinal fold, and the inserting and folding connecting rod 34 of the inserting and folding mechanism 3 drives the slider 32 to slide along the slide rail 31, and the inserting and folding plate 33 slides along with the slider 32 to pass through the horizontal fold to perform the second folding of the gauze strip; meanwhile, the buffer 46 resets and releases the pressing on the gauze strip; in this step, the folded gauze strip enters the accommodation groove 54;

[0057] In S2-2, the push plate 27 slides along the storage groove 28 driven by the cross arm 24, and pushes the folded gauze strip backward to reserve inserting and folding space for the next inserting and folding plate 33.

[0058] The above method uses the power transmission system 1 to synchronously drive the hook-fold pushing mechanism 2, the insert-fold mechanism 3, the pressing mechanism 4, and the transfer mechanism 5, enabling the synchronous linkage of each component mechanism. The speed of the whole machine is controlled by the servo commutator 11 of the power transmission system 1, and the transfer, first folding, second folding, and storage are coupled, so that the actions of each mechanism are not affected by the speed adjustment.

[0059] The above embodiments are only the preferred technical solutions of the present invention and should not be regarded as limitations on the present invention. The embodiments in this application and the features in the embodiments can be arbitrarily combined with each other without conflict. The protection scope of the present invention should be the technical solutions recorded in the claims, including the equivalent replacement solutions of the technical features in the technical solutions recorded in the claims.
