Technical Field
[0001] The present invention relates to a cotton stuffing and printing device and its process. Background Art
[0002] Today, with the increasingly better development of medical devices, the productivity of medical devices has greatly affected whether the medical cause can meet the needs of human society. Especially for some medical devices with special structures, the production has always been very difficult, and it is necessary to ensure one-time completion during the production process. After all, the fewer processes, the more it can avoid the contamination of medical devices during production. Therefore, reducing the production processes as much as possible can minimize the possible contamination in the assembly line production. Especially the operation of stuffing cotton into medical devices is a difficult point in the field of medical device production. How to achieve stuffing cotton on medical devices and simultaneously complete printing is a technical problem that urgently needs to be solved at present. Summary of the Invention
[0003] The purpose of the present invention is to provide a cotton stuffing and printing device and its process. Through a coaxially rotating filter element feeding component and a printing substrate feeding component, the printing substrate and the filter element are automatically stuffed with cotton, and the printed substrate stuffed with cotton is printed on a transmission chain to complete an automatic production device and its production process for cotton stuffing and printing.
[0004] To achieve the above purpose, the technical solution adopted by the present invention is:
[0005] A cotton stuffing and printing device, the printing device includes a fixing component, a filter element feeding component, a filter element feeding shaft, a printing substrate feeding component, a transmission component and a printing component;
[0006] The fixing component includes a base and wall plates. There are at least two wall plates which are detachably connected to the base. The wall plates are arranged opposite to each other, and both ends of the filter element feeding shaft are rotatably connected to the wall plates respectively;
[0007] The filter element feeding assembly includes a vibrating bowl, a filter element, a filter element channel, a push rod mechanism and a cam. The vibrating bowl contains the filter element. The filter element channel is arranged on the vibrating bowl. The filter element enters the filter element channel through the vibrating bowl. The push rod mechanism and the cam are arranged on the filter element feeding shaft with the filter element feeding shaft as the rotation center. The cam is a cylindrical structure with a flat end and a wavy circumferential edge at the other end. The flat end of the cam is detachably connected to the wall panel. The push rod mechanism includes a mounting plate, a push rod, a snap ring, a spring and a roller. The mounting plate is a disc-shaped structure. The middle of the mounting plate is fixedly connected to the filter element feeding shaft, and through holes for the push rod to pass through are arranged at the edge. One end of the push rod is rotatably connected with the roller, and the other end passes through the mounting plate and points to the filter element channel. The roller is in contact connection with the wavy circumference of the cam. A snap ring is arranged on the push rod between the mounting plate and the roller. The spring is sleeved on the push rod, one end of which is in contact connection with the snap ring, and the other end is in contact connection with the mounting plate.
[0008] The printed matter feeding assembly includes a printed matter, a feeding funnel, an indexing wheel and a pressing plate. The indexing wheel is cylindrical, and a plurality of slots are arranged on the circumferential edge of the indexing wheel. The slots are parallel to the axis of the indexing wheel. The filter element feeding shaft passes through the axis of the indexing wheel and is fixedly connected to the indexing wheel. A feeding retaining ring is arranged on the pressing plate. The outlet of the feeding funnel and the feeding retaining ring are respectively attached to the outer wall of the indexing wheel. The printed matter is placed in the feeding funnel. The printed matter cooperates with the slots, and the slots correspond to the push rods one by one.
[0009] The transmission assembly includes a first motor and a transmission chain. The first motor drives the filter element feeding shaft and the transmission chain. The transmission chain includes at least two and is arranged in parallel. A plurality of tooth positions are arranged on the transmission chain. The tooth positions cooperate with the printed matter, and the tooth positions of the transmission chain point to the indexing wheel.
[0010] The printing assembly includes a pushing mechanism and a printing mechanism. The pushing mechanism is used to push the printed matter on the transmission chain upward to contact the printing mechanism. The printing mechanism includes a second motor, a hub and a transfer rubber. The second motor drives the hub, and the transfer rubber is arranged on the outer wall of the hub.
[0011] The cotton-stuffing printing equipment adopting this technical solution rotates around the filter element feeding shaft. The push rod mechanism on the filter element feeding shaft rotates on the filter element feeding shaft driven by the first motor. The roller at the end of the push rod mechanism rolls on the surface of the cam. Since one end of the cam is a cylindrical structure with a wavy circular edge, the rotation along the upper surface of the cam enables the push rod of the push rod mechanism to follow the wavy outer periphery of the cam. The filter elements continuously entering the filter element channel from the vibrating disk will be driven by the continuous rotation of the push rod mechanism to enter the position in front of the push rod. As the push rod rotates along the cam, the filter elements are pushed out. Since the indexing wheel of the printing substrate feeding assembly also rotates with the rotation of the filter element feeding shaft, the slots on the indexing wheel correspond to the push rods one by one, and the openings of the printing substrates entering the indexing wheel also point to the push rods. When the push rod pushes out the filter elements, the filter elements can just be stuffed into the printing substrates, completing the cotton-stuffing action. The feeding funnel pointed to above the indexing wheel can accommodate the printing substrates for the operator to feed the printing substrates. The feeding retaining ring on the platen can limit the printing substrates within the indexing wheel to prevent them from falling out during the rotation. The printed products after cotton-stuffing will fall onto the teeth of the conveyor chain under the rotation of the indexing wheel and be sent to the printing mechanism. Through the rotation of the hub and the transfer rubber, the content to be printed is printed on the printing substrates.
[0012] As an improved technical solution of the cotton-stuffing printing equipment of the present invention:
[0013] The indexing wheel is provided with a vacuum part, a blowing part, air holes and an air inlet. The vacuum part and the blowing part are both arranged inside the indexing wheel. The vacuum part and the blowing part are in a relatively stationary state inside the indexing wheel and do not follow the indexing wheel. The vacuum part points to the feeding funnel and the feeding retaining ring, the blowing part points to the conveyor chain, the air holes are arranged at the bottom of the slots and penetrate the indexing wheel, and the air inlet is arranged on the side surface of the indexing wheel. The air inlet is externally connected to an air chamber.
[0014] The vacuum part and the blowing part provided on the indexing wheel are in a relatively stationary position inside the indexing wheel. That is, when the indexing wheel rotates externally, the vacuum part and the blowing part both continuously maintain a fixed position and continuously maintain the vacuum and blowing states. The vacuum part points to the feeding funnel and the feeding retaining ring, and the blowing part points to the conveyor chain. There are air holes at the bottom of the slots on the indexing wheel. When the printing substrates fall onto the slots of the indexing wheel, as long as the slots point to the feeding funnel and the feeding retaining ring, they are within the pointing area of the vacuum part, and the printing substrates will be continuously adsorbed in the slots due to the suction of the vacuum, so that the printing substrates will not fall or shift in position during the cotton-stuffing process when the indexing wheel rotates. When the slots rotate to point to the conveyor chain and enter the area of the blowing part, the gas blown out from the air holes can more smoothly blow the printing substrates onto the conveyor chain, avoiding the printing substrates being repeatedly driven by the indexing wheel to rotate another circle and repeating the cotton-stuffing.
[0015] As an improved technical solution of the cotton plugging printing equipment of the present invention:
[0016] The printed material feeding assembly further includes a filter element feeding tray, which is detachably connected to the indexing wheel. The filter element feeding tray is arranged between the indexing wheel and the push rod. The filter element feeding tray is of a disc-shaped structure, and a number of plug holes are evenly distributed on the filter element feeding tray. The plug holes correspond to the slots on the indexing wheel one by one. The plug holes are of a frustum-shaped structure with unequal diameters on the left and right, and become smaller from the direction of the push rod to the indexing wheel.
[0017] The filter element feeding tray included in the printed material feeding assembly is arranged between the indexing wheel and the push rod. The provided plug holes correspond to the slots on the indexing wheel one by one. All filter elements need to pass through the filter element feeding tray before entering the printed material. Since the filter element is made of cotton, when entering the printed material from the push rod, if it is not compressed and formed, on the one hand, if the cotton plugging does not enter the printed material, the yield rate of plugging the filter element will not be high; on the other hand, it is very easy to bring out the inserted filter element from the printed material again. Therefore, the plug holes are of a frustum-shaped structure with unequal diameters on the left and right, and become smaller from the direction of the push rod to the indexing wheel. During the process of inserting the filter element from the push rod into the printed material, the filter element enters the printed material after a certain degree of compression. Since it becomes smaller from the push rod to the indexing wheel, it is difficult for the filter element to be taken out from the small hole diameter when the push rod withdraws. Thus, the yield rate of cotton plugging can be improved.
[0018] As an improved technical solution of the cotton plugging printing equipment of the present invention:
[0019] The wavy circular periphery of the cam has only one highest point, which points to the middle part of the feeding retaining ring. The two ends of the highest point are gently transitioned to all the remaining lowest points respectively.
[0020] The only highest point of the wavy circumference of the cam points to the middle part of the feeding retaining ring. Therefore, there is only one cotton plugging position during the pushing process of the push rod. The two ends of the highest point are gently transitioned to all the remaining lowest points respectively.
[0021] As an improved technical solution of the cotton plugging printing equipment of the present invention:
[0022] The pushing mechanism includes a printing lower die and a dialing piece. The printing lower die is arranged in the middle of the conveying chain. The printing lower die includes a fixed part and a lifting part. The fixed part is fixed on the wallboard and the horizontal plane of its top surface is lower than the bottom of the tooth position. The lifting part is fixedly connected to the end of the fixed part, and its top surface is an inclined surface. The lifting part extends from the bottom of the tooth position to a position higher than the top of the tooth position. The printing lower die does not contact the conveying chain; the dialing piece is arranged in parallel with the printing lower die. The rack on the dialing piece can dial the printed material on the conveying chain onto the lifting part. The second motor drives the dialing piece. The distance between the transfer rubber and the lifting part just allows the printed material to pass through.
[0023] The printed product with cotton stuffing is transmitted to the printing assembly on the conveyor chain, and the printed product is transferred to the lifting part through the fixed part and the lifting part of the printing lower mold, and the printed product is pushed to the lifting part through the rack of the dial wheel. During the rotation of the wheel hub, the transfer rubber on the wheel hub will directly act on the printed product, driving the printed product to rotate and completing the printing on the printed product.
[0024] As the improved technical solution of the cotton plug printing equipment of the present invention:
[0025] The pushing mechanism further comprises a transition block, which is detachably connected to the end of the lifting portion, and the printed product is introduced onto the tooth position of the conveying chain through the transition block.
[0026] The printed product will pass through the transition block, and the buffering of the transition block can make the printed product more smoothly introduced into the rack of the conveyor chain.
[0027] As the process of the cotton plug printing device of the present invention, its specific working method is as follows:
[0028] S1, after the filter element is vibrated and aligned in the vibration plate, it is stacked from top to bottom and placed in the filter element channel for standby use, and the printed product is placed in the feed funnel for standby use;
[0029] S2, the filter element feed shaft is driven by the first motor to drive the mounting plate to rotate, and the push rod on the mounting plate is driven to rotate by the mounting plate. Due to the action of the spring on the push rod, the push rod is forced to continuously press on the cam to the left, and the roller at the end of the push rod rolls on the wavy circumferential edge of the cam, and as it rises and falls, it pushes the push rod to move to the right when it rolls to the highest point;
[0030] S3, during the rotation of the filter element feed shaft, the indexing wheel is driven to rotate at the same time. A feed funnel is placed above the indexing wheel. Since there are slots for matching substrates on the indexing wheel, the substrates will fall into the slots one by one during the rotation of the indexing wheel, and driven by the rotation of the indexing wheel, the loading baffle ring fitted with the indexing wheel can push the excess substrates back into the feed funnel. The slot corresponds to the push rod, and the highest point of the cam points to the middle part of the loading baffle ring. When the push rod rotates to the highest point, it pushes the filter element in the filter element channel into the substrate. Then, during the rotation, the push rod withdraws from the inner cavity of the substrate. The substrate continues to rotate downward driven by the indexing wheel and finally falls onto the conveying chain under the indexing wheel.
[0031] S4, the teeth on the two parallel conveyor chains can just clamp the printed product, driving the printed product to be sent to the printing mechanism. When the conveyor chain passes through the printing lower mold, the printed product is lifted to the lifting part of the printing lower mold by the turning of the dial wheel. The gap between the lifting part and the transfer rubber on the hub can just accommodate the rolling of the printed product. The pattern on the transfer rubber is printed on the printed product. After printing, the printed product returns to the conveyor chain through the transition block.
[0032] As an improved technical solution of the process of the cotton plug printing device of the present invention:
[0033] In S3, an air chamber is provided outside the indexing wheel, connecting the vacuum part and the blowing part inside the indexing wheel. The air holes at the bottom of the indexing wheel slot are used for sucking and blowing the printed matter. The vacuum part points to the feed funnel and the loading baffle ring, and the blowing part points to the conveying chain. After the printed matter enters the slot of the indexing wheel from the feed funnel, it is sucked by the air holes at the bottom of the slot, so that the printed matter is directly adsorbed on the indexing wheel and will not fall off. At the same time, it also prevents the printed matter from loosening during the rotation of the indexing wheel. As the indexing wheel rotates, when it is close to the middle part of the loading baffle ring, the filter element is pushed into the printed matter by the push rod. When the indexing wheel continues to rotate and is close to the conveying chain, the air holes at the bottom of the slot are converted from suction to blowing, and the printed matter is blown out of the slot, so that the printed matter falls onto the conveying chain.
[0034] As an improved technical solution of the process of the cotton plug printing device of the present invention:
[0035] In S3, a filter element feed tray is provided between the indexing wheel and the push rod. When the filter element is pushed by the push rod toward the printed product on the indexing wheel slot, the filter element can be compressed and plugged into the printed product through the left and right unequal diameter plug holes on the filter element feed tray.
[0036] After adopting the above scheme, the beneficial effects of the present invention are:
[0037] The cotton plugging printing equipment and process using this technical solution, through the synchronous rotation of the push rod mechanism and the dividing wheel on the filter element feed shaft, the push rod and the grooves on the dividing wheel correspond one to one, the filter element channel on the push rod mechanism introduces the filter element onto the push rod, and the printed matter in the feed funnel enters the groove of the dividing wheel. During the rotation of the push rod mechanism, the end of the push rod is pushed by the cam to push the filter element into the printed matter to complete the cotton plugging action. The structure of the mechanism is stable and can complete the transmission cotton plugging action under the synchronous drive of the first motor. Moreover, the printed matter after cotton plugging can be sent to the printing component through the transmission chain and rotated by the wheel hub. The transfer rubber acts on the printed matter to realize the printing of the content. BRIEF DESCRIPTION OF THE DRAWINGS

The spring 244 is sleeved on the push rod 242 and one end is in contact connection with the snap ring 243, and the other end is in contact connection with the mounting plate 241;
[0048] The printed matter feeding assembly 4 includes a printed matter 41, a feeding funnel 42, an indexing wheel 43 and a pressing plate 44. The indexing wheel 43 is cylindrical, and a plurality of slots 431 are provided on the circumferential edge of the indexing wheel 43. The slots 431 are parallel to the axis of the indexing wheel 43. The filter element feeding shaft 3 passes through the axis of the indexing wheel 43 and is fixedly connected to the indexing wheel 43. A feeding retaining ring 441 is provided on the pressing plate 44. The discharging port 421 of the feeding funnel 42 and the feeding retaining ring 441 are respectively attached to the outer wall of the indexing wheel 43. The printed matter 41 is placed in the feeding funnel 42. The printed matter 41 cooperates with the slots 431, and the slots 431 correspond to the push rods 242 one by one;
[0049] The transmission assembly 5 includes a first motor 51 and a transmission chain 52. The first motor 51 drives the filter element feeding shaft 3 and the transmission chain 52. The transmission chain 52 includes at least two and is arranged in parallel. A plurality of tooth positions 521 are provided on the transmission chain 52. The tooth positions 521 cooperate with the printed matter 41, and the tooth positions 521 of the transmission chain 52 point to the indexing wheel 43;
[0050] The printing assembly 6 includes a pushing mechanism 61 and a printing mechanism 62. The pushing mechanism 61 is used to push the printed matter 41 on the transmission chain 52 upward to contact the printing mechanism 62. The printing mechanism 62 includes a second motor 621, a hub 622 and a transfer rubber 623. The second motor 621 drives the hub 622, and the transfer rubber 623 is arranged on the outer wall of the hub 622.
[0051] A vacuum part 4311, a blowing part 4312, air holes 4313 and an air inlet 4314 are provided on the above-mentioned indexing wheel 43. The vacuum part 4311 and the blowing part 4312 are both arranged inside the indexing wheel 43. The vacuum part 4311 and the blowing part 4312 are in a relatively stationary state inside the indexing wheel 43 and do not follow the indexing wheel 43. The vacuum part 4311 points to the feeding funnel 42 and the feeding retaining ring 441. The blowing part 4312 points to the transmission chain 52. The air holes 4313 are provided at the bottom of the slots 431 and penetrate through the indexing wheel 43. The air inlet 4314 is provided on the side surface of the indexing wheel 43, and the air inlet 4314 is externally connected to an air chamber.
[0052] The above-mentioned printed matter feeding assembly 4 further includes a filter element feeding disk 45. The filter element feeding disk 45 is detachably connected to the indexing wheel 43. The filter element feeding disk 45 is arranged between the indexing wheel 43 and the push rod 242. The filter element feeding disk 45 has a disk-shaped structure. A plurality of plug holes are evenly distributed on the filter element feeding disk 45. The plug holes respectively correspond to the slots 431 on the indexing wheel 43 one by one. The plug holes have a frustum-shaped structure with unequal diameters on the left and right, and gradually become smaller from the direction of the push rod to the indexing wheel 43.
[0053] The wavy circumferential edge of the above-mentioned cam 25 has only one highest point, which points to the middle part of the loading retaining ring 441, and both ends of the highest point are gently transitioned to all the remaining lowest points.
[0054] The above-mentioned pushing mechanism 61 includes a printing lower die 611 and a dial plate 612. The printing lower die 611 is arranged in the middle of the conveying chain 52. The printing lower die 611 includes a fixing part 6111 and a lifting part 6112. The fixing part 6111 is fixed on the wall panel 12 and the horizontal plane of its top surface is lower than the bottom of the tooth position 521. The lifting part 6112 is fixedly connected to the end of the fixing part 6111, and its top surface is an inclined surface. The lifting part 6112 extends from the bottom of the tooth position 521 to a position higher than the top of the tooth position 521. The printing lower die 611 does not contact the conveying chain 52. The dial plate 612 is arranged in parallel with the printing lower die 611. The rack 6121 on the dial plate 612 can dial the printed product 41 on the conveying chain 52 onto the lifting part 6112. The second motor 621 drives the dial plate 612, and the distance between the transfer rubber 623 and the lifting part 6112 just allows the printed product 41 to pass through.
[0055] The above-mentioned pushing mechanism 61 further includes a transition block 613. The transition block 613 is detachably connected to the end of the lifting part 6112, and the printed product 41 is introduced onto the tooth position 521 of the conveying chain 52 through the transition block 613.
[0056] The cotton stuffing printing equipment adopting this technical solution rotates around the filter element feeding shaft 3. The push rod mechanism 24 on the filter element feeding shaft 3 rotates on the filter element feeding shaft 3 driven by the first motor 51. The roller 245 at the end of the push rod mechanism 24 rolls on the surface of the cam 25. Since one end of the cam 25 has a wavy cylindrical structure at the peripheral edge, the rotation along the upper surface of the cam 25 can make the push rod 242 of the push rod mechanism 24 follow the wavy outer periphery of the cam 25. The filter element 22 continuously entering the filter element channel 23 from the vibrating disk 21 will be driven by the continuous rotation of the push rod mechanism 24 to enter the position in front of the push rod 242. As the push rod 242 rotates along the cam 25, the filter element 22 is pushed out. Since the indexing wheel 43 of the printing material feeding assembly 4 also rotates with the rotation of the filter element feeding shaft 3, the slots 431 on the indexing wheel 43 correspond one by one to the push rod 242, and the opening of the printing material 41 entering the indexing wheel 43 also points to the push rod 242. When the push rod 242 pushes out the filter element 22, the filter element 22 can just be stuffed into the printing material 41, completing the cotton stuffing action. The feeding funnel 42 pointed to above the indexing wheel 43 can accommodate the printing material 41 for the operator to feed the printing material 41. The feeding retaining ring 441 on the pressing plate 44 can limit the printing material 41 within the indexing wheel 43 to prevent it from falling out during the rotation. The printed product 41 after completing the cotton stuffing will fall onto the tooth position 521 of the conveyor chain 52 under the rotation of the indexing wheel 43, and the printed product 41 is sent to the printing mechanism 62. Through the rotation of the hub 622 and the transfer rubber 623, the content to be printed is printed on the printed product 41.
[0057] A vacuum part 4311 and a blowing part 4312 are provided on the indexing wheel 43 and are in a relatively stationary position within the indexing wheel 43. That is, when the indexing wheel 43 rotates externally, the vacuum part 4311 and the blowing part 4312 both remain in a fixed position and continuously maintain the vacuum and blowing states. The vacuum part 4311 points to the feeding funnel 42 and the feeding retaining ring 441, and the blowing part 4312 points to the conveyor chain 52. There are air holes 4313 at the bottom of the slots 431 on the indexing wheel 43. When the printed product 41 falls onto the slot 431 of the indexing wheel 43, as long as the slot 431 points to the feeding funnel 43 and the feeding retaining ring 441, it is in the pointing area of the vacuum part 4311, and the printed product 41 will be continuously adsorbed in the slot 431 due to the vacuum suction, so that the printed product 41 will not fall or shift in position during the cotton stuffing process when the indexing wheel 43 rotates. When the slot 431 rotates to point to the conveyor chain 52 and enters the area of the blowing part 4312, the gas blown out from the air hole 4313 can more smoothly blow the printed product 41 onto the conveyor chain 52, preventing the printed product 41 from being repeatedly driven by the indexing wheel 43 to rotate one more circle and repeat the cotton stuffing.
[0058] The filter element feeding tray 45 included in the printed matter feeding assembly 4 is arranged between the indexing wheel 43 and the push rod 242. The provided plug holes correspond one by one to the slots 431 on the indexing wheel 43. All filter elements 22 need to pass through the filter element feeding tray 45 before entering the printed matter 41. Since the filter element 22 is made of cotton, when it enters the printed matter 41 from the push rod 242, if it is not compression-molded, on the one hand, if the cotton plug does not enter the printed matter 41, it will lead to a low yield rate of plugging the filter element 22. On the other hand, it is very easy to bring out the inserted filter element 22 from the printed matter 41 again. Therefore, the plug hole is a frustum-shaped structure with unequal diameters on the left and right, getting smaller from the direction of the push rod 242 to the indexing wheel 43. During the process of the filter element 22 being inserted into the printed matter 41 from the push rod 242, the filter element 22 enters the printed matter 41 after a certain degree of compression. Since it gets smaller from the push rod 242 to the indexing wheel 43, when the push rod 242 withdraws, it is very difficult for the filter element 22 to be taken out from the small hole diameter, thereby improving the yield rate of cotton plugging.
[0059] The only highest point of the wavy circumference of the cam 25 points to the middle part of the feeding retaining ring 441. Therefore, there is only one cotton plugging position during the pushing process of the push rod 242, and both ends of the highest point are gently transitioned to the remaining lowest points respectively.
[0060] The printed matter 41 with cotton plugged is conveyed on the conveying chain 52 to the printing assembly 6. Through the fixing part 6111 and the lifting part 6112 of the printing lower die 611, the printed matter 41 is transitioned to the lifting part 6112, and the printed matter 41 is dialed to the lifting part 6112 through the rack 6121 of the dialing piece 612. During the rotation of the hub 622, the transfer rubber 623 on the hub 622 will directly act on the printed matter 41, driving the printed matter 41 to rotate and completing the printing on the printed matter 41.
[0061] The printed matter 41 after printing will pass through the transition block 613. Through the buffering of the transition block 613, the printed matter 41 can be more smoothly introduced onto the rack 521 of the conveying chain 52.
[0062] As the process of the cotton plugging and printing equipment of the present invention, its specific working method is as follows:
[0063] S1, after the filter elements 22 are aligned by vibration in the vibrating bowl 21, they are stacked layer by layer from top to bottom and enter the filter element channel 23 for standby. The printed matter 41 is placed in the feeding funnel 42 for standby;
[0064] S2. Driven by the first motor 51, the filter element feed shaft 3 drives the mounting disc 241 to rotate. The push rod 242 on the mounting disc 241 is driven by the mounting disc 241 to rotate. Due to the action of the spring 244 on the push rod 242, the push rod 242 is forced to continuously press leftward against the cam 25. The roller 245 at the end of the push rod 242 rolls on the wavy peripheral edge of the cam 25. As it rises and falls, when it rolls to a high point, it pushes the push rod 242 to move rightward;
[0065] S3. During the rotation of the filter element feed shaft 3, the indexing wheel 43 is simultaneously driven to rotate. An inlet funnel 42 is placed above the indexing wheel 43. Since there are slots 431 on the indexing wheel 43 that cooperate with the printed matter 41, during the rotation of the indexing wheel 43, the printed matter 41 will successively fall into the slots 431, and driven by the rotation of the indexing wheel 43, the feeding retaining ring 441 that fits with the indexing wheel 43 can push the excess printed matter 41 back into the inlet funnel 42. The slots 431 correspond to the push rod 242, and the highest point of the cam 25 points to the middle part of the feeding retaining ring 441. When the push rod 242 rotates to the highest point, it pushes the filter element 22 in the filter element channel 23 into the printed matter 41. Then, during the rotation process, the push rod 242 withdraws from the inner cavity of the printed matter 41, and the printed matter 41 continues to rotate downward driven by the indexing wheel 43 and finally falls onto the conveyor chain 52 under the indexing wheel 43;
[0066] An air chamber is provided outside the indexing wheel 43, which communicates with the vacuum part 4311 and the blowing part 4312 inside the indexing wheel 43. The air holes 4313 at the bottom of the slots 431 of the indexing wheel 43 are used for sucking and blowing the printed matter 41. The vacuum part 4311 points to the inlet funnel 42 and the feeding retaining ring 441, and the blowing part 4312 points to the conveyor chain 52. After the printed matter 41 enters the slots 431 of the indexing wheel 43 from the inlet funnel 42, it is sucked by the air holes 4313 at the bottom of the slots 431, so that the printed matter 41 is directly adsorbed on the indexing wheel 43 and will not fall, and at the same time, the loosening of the printed matter 41 during the rotation of the indexing wheel 43 is also avoided. As the indexing wheel 43 rotates, when it reaches the middle part near the feeding retaining ring 441, the filter element 22 is pushed into the printed matter 41 by the push rod 242. When the indexing wheel 43 continues to rotate to near the conveyor chain 52, the air holes 4313 at the bottom of the slots 431 are switched from suction to blowing, and the printed matter 41 is blown out of the slots 431, so that the printed matter 41 falls onto the conveyor chain 52;
[0067] A filter element feed disc 45 is also provided between the indexing wheel 43 and the push rod 242. When the filter element 22 is pushed by the push rod 242 into the printed matter 41 in the slots 431 of the indexing wheel 43, it can be compressed and inserted into the printed matter 41 through the left and right unequal-diameter plug holes on the filter element feed disc 25.
[0068] S4, the teeth 521 on the two parallel conveyor chains 52 can just clamp the printed product 41, and drive the printed product 41 to be sent to the printing mechanism 62. When the conveyor chain 52 passes through the printing lower mold 611, the printed product 41 is lifted to the lifting part 6112 of the printing lower mold 611 by the turning of the dial plate 612. The gap between the lifting part 6112 and the transfer rubber 623 on the hub 622 can just accommodate the rolling of the printed product 41. The pattern on the transfer rubber 623 is printed on the printed product 41. After printing, the printed product 41 returns to the conveyor chain 52 through the transition block 613.
