Description

Technical Field

[0001] The present invention belongs to the technical field of medical supplies production equipment, and particularly relates to a fully automatic medical chip implantation and sewing device. Background Art

[0002] Among medical supplies, there is a type of gauze used during surgery. This gauze is mainly used for hemostasis, wiping blood, sucking blood or body fluids during the surgical process. In some surgeries, the wound is relatively large and more gauze is used. After the surgery, the gauze needs to be removed from the patient's body. After being soaked in blood, the gauze becomes softer and its color is the same as that of blood, and there is a situation where the gauze is missed during removal. Leaving the dressing in the human body will not only affect the patient's recovery, but also cause them pain such as difficult wound healing, pain, and infection, and may even endanger life in severe cases.

[0003] For this reason, a type of gauze with a chip inside has been proposed. This type of gauze is convenient for monitoring whether there is any gauze left in the human wound after surgery. The process of loading the chip is as follows: implant the chip into the folded double-layer gauze, sew the open back of the gauze, then cut the gauze into sections. At this time, both sides of the gauze are open, and then the open sides are sewn with a hem. However, each step in the entire production process of the gauze with an implanted chip is completed manually. Manual operation is inefficient, has potential safety hazards, and greatly increases labor costs.

[0004] Therefore, there is an urgent need for a fully automatic production device. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a fully automatic medical chip implantation and sewing device that can efficiently and safely produce gauze with an implanted chip in view of the above-mentioned current situation of the prior art.

[0006] The technical solution adopted by the present invention to solve the above technical problem is: a fully automatic medical chip implantation and sewing device, including a workbench, characterized in that it further includes:

[0007] A chip implantation mechanism, arranged on the workbench surface, used to push the chip through the open back of the folded gauze into the gauze;

[0008] A presser foot mechanism, arranged above the workbench, and having a pressing member that can press the gauze on the workbench surface;

[0009] A conveying mechanism, arranged on the workbench, and the power output end of the conveying mechanism is drivingly connected to the presser foot mechanism, used to at least drive the presser foot mechanism to move along the conveying direction of the gauze;

[0010] The first sewing mechanism is arranged on the tabletop, downstream of the chip implantation mechanism along the conveying direction of the gauze, and is used for hemming and sewing the open rear side of the gauze;

[0011] The cutting mechanism is arranged on the tabletop, downstream of the first sewing mechanism along the conveying direction of the gauze, and is used for cutting the cloth after hemming and sewing;

[0012] The deflection mechanism acts on the presser foot mechanism to drive the pressing member to rotate 90° on the tabletop, so that the openings on the left and right sides of the gauze are arranged front and back; and

[0013] Two groups of second sewing mechanisms are arranged on the tabletop and are respectively located on the left and right sides of the pressing member, so as to perform hemming and sewing on the corresponding side of the gauze opening. Along the conveying direction of the gauze, the second sewing mechanism is downstream of the first sewing mechanism.

[0014] There are various structural forms of the conveying mechanism. It can adopt the form of a cylinder, and the presser foot mechanism is arranged at the output end of the cylinder; it can also adopt the form of a combination of a motor, a screw rod and a nut. The screw rod is installed on the output shaft of the motor, and the presser foot mechanism is arranged on the nut; preferably, however, a fixed plate relatively fixed to the workbench is arranged above the workbench. The conveying mechanism includes a second motor, a conveyor belt, a connecting shaft arranged side by side and spaced apart from the output shaft of the second motor, and a driving wheel and a driven wheel arranged at intervals in the left-right direction. The second motor and the connecting shaft are both installed on the fixed plate, and the output shaft of the second motor extends in the front-back direction. The driving wheel and the driven wheel are respectively installed on the output shaft of the second motor and the connecting shaft. The conveyor belt surrounds the driving wheel and the driven wheel, and moves relative to the fixed plate under the drive of the driving wheel and the driven wheel. The presser foot mechanism is arranged on the conveyor belt and moves around the connecting shaft with the conveyor belt. That is, the presser foot mechanism makes a circular motion relative to the fixed plate. During the working process of the conveying mechanism, a gauze bag with a chip inside is continuously prepared.

[0015] There are various structural forms of the presser foot mechanism. Preferably, however, the presser foot mechanism includes:

[0016] A sleeve, arranged vertically. The upper end of the sleeve is connected to the conveyor belt, and the inside of the sleeve has a cavity;

[0017] A connecting rod, arranged vertically and located above the workbench. A part of the connecting rod is located in the cavity of the sleeve, and a pressing member is installed at the lower end of the connecting rod and located below the sleeve; and

[0018] An elastic member acts on the connecting rod to make the connecting rod always have a tendency to move downward, so that the pressing member presses the folded double-layer gauze on the tabletop.

[0019] In order to automatically implant the chip into the gauze and overcome the cumbersome nature and low efficiency caused by manual placement of the chip, the chip implanting mechanism includes:

[0020] A driving mechanism, whose power output end is connected to the link drive and is used to drive the link to move upward;

[0021] A pushing mechanism, which is arranged on the workbench and has a push rod that can move back and forth. The chip is located in front of the push rod and on the movement path of the push rod. When the push rod is in the forward movement state, the chip can be pushed into the gauze through the rear opening of the gauze.

[0022] There are various structural forms of the limiting member. However, from the perspective of reducing friction, preferably, a limiting member is installed at a position where the link is below the sleeve. The limiting member is located above the power output end of the driving mechanism and on the movement path of the power output end of the driving mechanism.

[0023] In order to drive the gauze to deflect automatically and overcome the cumbersome nature and low efficiency caused by manual deflection, a through groove communicating with the cavity and extending in the up and down direction is provided on the side wall of the sleeve. A guiding member is provided on the side wall of the link. The deflection mechanism includes:

[0024] A transmission rod, which is located in the through groove and is arranged to be able to move up and down relative to the sleeve. A first sliding member passing through the through groove is relatively fixed on the side wall of the transmission rod. A driving portion is provided on the fixed plate, which acts on the transmission rod to make the transmission rod move up and down when the conveyor belt is in motion; and

[0025] A bushing, which is arranged in the cavity and sleeved around the link. A guiding groove extending along the length direction of the link and guidingly cooperating with the guiding member is provided on the inner peripheral wall of the bushing. A sliding groove that is slidably engaged with the first sliding member and at least partially spirals downward is provided on the outer peripheral wall of the bushing. Thus, when the transmission rod is in the up and down movement state, the bushing and the link are driven to rotate relative to the sleeve, and then the pressing member drives the fabric to rotate.

[0026] There are various structural forms of the driving part. It can be directly formed on the fixing plate or realized by using an additional driving mechanism. However, from the perspective of cost reduction and structure simplification, the driving part is an annular slideway formed on the fixing plate and surrounding the output shaft of the second motor and the connecting shaft and presenting an annular shape. The upper end of the transmission rod has a first roller that slidably cooperates with this annular slideway. The part of the annular slideway located below the connecting shaft and extending along the left - right direction is defined as the lower slideway. The lower slideway includes a first slide section, a second slide section, and a third slide section that are sequentially connected along the conveying direction of the gauze. The first slide section and the third slide section both extend along the left - right direction, and the first slide section is located below the third slide section. The second slide section gradually slopes upward along the conveying direction of the fabric and is located at the position corresponding to between the second sewing mechanism and the cutting mechanism.

The outer peripheral wall of the main body part includes a first arc - shaped section and a second arc - shaped section arranged at intervals in the left - right direction, and an upper slide section and a lower slide section located between the first arc - shaped section and the second arc - shaped section and both extending along the left - right direction. The lower slide section is located below the upper slide section. The arc - shaped part is formed on the outer wall surfaces of the second arc - shaped section and the lower slide section and is arranged in a staggered manner with the connecting plate. The first slide section is located on the bottom wall of the arc - shaped part. The connecting plate is partially located below the arc - shaped part, and the second slide section is formed between the connecting plate and the arc - shaped part, and the third slide section is formed between the connecting plate and the main body part. The part of the annular slideway except for the third slide section and the second slide section is located on the outer peripheral wall of the main body part. Additionally, the above - mentioned annular slideway can also be directly formed by opening on the fixing plate.

[0028] There are various structural forms of the chute. It can only adopt the form of the second extension groove or the form of the cooperation of the first, second, and third extension grooves. However, preferably, the chute includes a first extension groove, a second extension groove, and a third extension groove that are sequentially connected from top to bottom. The first extension groove and the third extension groove both extend vertically and are arranged at intervals along the circumferential direction of the bushing. The second extension groove gradually slopes downward and extends toward the third extension groove from top to bottom.

[0029] In order to make the presser - foot mechanism move more smoothly driven by the conveying mechanism, a fixing part relatively fixed to the sleeve is arranged above the sleeve. The front and rear sides of the fixing part are respectively relatively fixed with a front plate and a rear plate. The conveyor belt is located between the front plate and the rear plate and is connected to the front plate. Second rollers are installed on both the front plate and the rear plate. The main body part has an annular slideway that slidably cooperates with the second roller at the position corresponding to the second roller.

Subsequently, the deflection mechanism drives the gauze sections to deflect, and at this time, the openings on the opposite sides of the gauze are arranged along the front and back, and when the gauze moves to the second sewing mechanism, the second sewing mechanism hems the openings on the corresponding sides of the gauze, completing the production of the gauze with the built-in chip. The whole process is efficient and convenient, overcoming the problems of low efficiency, high labor cost and labor safety hazards brought about by manual production, and can better meet production needs.

In this embodiment, the conveying direction of the gauze is from right to left, that is, along the Figure 1 And Figure 3 direction indicated by the arrow C in. The fabric in this embodiment is the gauze. The front-back direction is specifically referred to the direction indicated by the arrow in Figure 1 .

[0051] As Figure 1 and Figure 3 shown, the conveying mechanism 4 is disposed on the workbench 1, and the power output end of the conveying mechanism 4 is drivingly connected to the presser foot mechanism 3 to drive the presser foot mechanism 3 to move along the conveying direction of the gauze. In this embodiment, the conveying mechanism drives the presser foot mechanism 3 to move circumferentially. Above the workbench 1, a fixing plate 7 fixedly connected to the workbench 1 is provided. The aforementioned conveying mechanism 4 includes a second motor 41, a conveyor belt 42, a connecting shaft 43 arranged side by side and at intervals with the output shaft of the second motor 41, and a driving wheel 44 and a driven wheel 45 arranged at intervals in the left - right direction. Both the second motor 41 and the connecting shaft 43 are installed on the fixing plate 7, and the output shaft of the second motor 41 extends in the front - rear direction. The driving wheel 44 and the driven wheel 45 are respectively installed on the output shaft of the second motor 41 and the connecting shaft 43. The conveyor belt 42 is wound around the periphery of the driving wheel 44 and the driven wheel 45 and moves relative to the fixing plate 7 under the drive of the driving wheel 44 and the driven wheel 45. The above - mentioned presser foot mechanism 3 is arranged on the conveyor belt 42, so the presser foot mechanism 3 moves around the connecting shaft 43 along with the conveyor belt 42, that is, the presser foot mechanism 3 makes a circular motion, and the presser foot mechanism 3 is located above the workbench 1. The above - mentioned driving wheel and driven wheel are both gears, and the conveyor belt 42 is a transmission chain meshing with the aforementioned gears.

[0052] As Figure 1 shown, there are multiple groups of presser foot mechanisms 3, which are arranged at intervals along the length direction of the conveyor belt. The structures of each group of presser foot mechanisms 3 are the same. The following takes one group as an example for description. As Figures 2 to 9 shown, the aforementioned presser foot mechanism 3 has a pressing member 36 capable of pressing the gauze on the tabletop 10 of the workbench 1. In this embodiment, the presser foot mechanism 3 includes a sleeve 31, a connecting rod 32, and an elastic member. Among them, the sleeve 31 is arranged vertically, and the upper end of the sleeve 31 is fixedly connected to a fixing member 39. The aforementioned fixing member 39 is connected to the conveyor belt 42. Above the sleeve 31, a fixing member 39 fixedly connected to the sleeve 31 is provided. Front plates 393 and rear plates 394 are respectively fixedly connected to the front and rear sides of the fixing member 39. The conveyor belt 42 is located between the front plate 393 and the rear plate 394 and is connected to the front plate 393. Third rollers 395 are installed on both the front plate 393 and the rear plate 394. The main body portion 73 has an annular slideway 75 slidably engaged with the third roller 395 at a position corresponding to the third roller 395.

[0053] The interior of the aforementioned sleeve 31 has a cavity 310. As Figures 4 to 7As shown, the above-mentioned cavity 310 includes an upper channel 3101 and a lower channel 3102 that are connected in sequence from top to bottom. A step portion 3103 is formed by laterally extending the peripheral side of the top of the lower channel 3102, and the step portion 3103 is the bottom wall of the upper channel 3101. In addition, a through groove 311 that is connected to the cavity 310 and extends along the up and down direction is provided on the side wall of the sleeve 31 corresponding to the upper channel 3101. The connecting rod 32 is arranged vertically and is located above the workbench 1, and a part of the connecting rod 32 is located in the cavity 310 of the sleeve 31. The above-mentioned pressing member 36 is arranged at the lower end of the connecting rod 32 and is located below the sleeve 31. In this embodiment, the pressing member 36 includes a pressing plate 361 that gradually slopes forward from top to bottom. The bottom surface of the pressing plate 361 has a groove 3611 that is recessed upward at a position adjacent to the front side to position the chip in the fabric. Usually, the chip is located in a cylindrical tube 01. The cross-section of the groove 3611 is semi-circular. In order to better position the chip, a flexible member that extends downward is provided in the groove 3611. When the chip is implanted into the fabric, the flexible member presses against the chip to prevent the chip from moving.

[0054] As Figure 10 shown, the workbench 1 is provided with a guiding channel 13 that extends along the front and back directions. The side portion of the guiding channel 13 has a feeding channel 16 for the chip to enter, and the feeding channel 16 is connected to the guiding channel 13. The chip implanting mechanism 2 is arranged on the tabletop 10 of the workbench 1 and is used to push the chip through the rear opening of the folded gauze into the gauze. In this embodiment, the chip implanting mechanism 2 includes a driving mechanism and a pushing mechanism 35. Among them, the power output end of the driving mechanism is drivingly connected to the connecting rod 32 to drive the connecting rod 32 to move upward. As Figure 2 shown, a limiting member is installed on the connecting rod 32. As Figures 1 to 9 shown, the limiting member is a second roller 321, and the rotation axis of the second roller 321 is along the front and back directions. An installation plate 12 that is relatively fixed to the workbench 1 is arranged above the workbench 1. The driving mechanism is a first cylinder 33 arranged on the installation plate 12, and a pushing plate 331 that pushes the second roller 321 is installed at the power output end of the first cylinder 33. The second roller 321 is located above the pushing plate 331 and is on the movement path of the pushing plate 331.

[0055] As Figure 10 and Figure 11As shown in the figure, the pushing mechanism 35 is arranged on the workbench 1 and includes a push rod 351, a first motor 350, a driving gear 352, a driven gear 353 and a transmission belt 354. The push rod 351 can move in the front-back direction, and the above-mentioned guiding channel 13 extends along the moving direction of the push rod 351. The aforesaid push rod 351 can be located within the guiding channel 13 and move along this guiding channel 13. The above-mentioned chip is located in front of the push rod 351 and on the moving path of the push rod 351. When the push rod 351 is in the forward moving state, the chip can be pushed into the gauze through the rear open end of the gauze. The existence of multiple pressing foot mechanisms on the conveyor belt can continuously convey the gauze towards the first sewing mechanism 6. At the same time, when the push rod continuously pushes the chip forward, in cooperation with the push rod 351, the chip can be continuously implanted into the gauze.

[0056] In this embodiment, in order for the push rod 351 to move in the front-back direction, the output shaft of the first motor 350 extends in the left-right direction. The driving gear 352 is installed on the output shaft of the first motor 350. The driven gear 353 is located in front of or behind the driving gear 352. The transmission belt 354 is wound around the periphery of the driving gear 352 and the driven gear 353 and moves under the drive of the driving gear 352 and the driven gear 353. The push rod 351 is installed at the rear part of the upper surface of the transmission belt 354 near the rear end.

[0057] The first sewing mechanism 6 is arranged on the table 10 and is located downstream of the chip implanting mechanism 2 along the conveying direction of the gauze, and is used for hemming and sewing the rear open end of the gauze. The cutting mechanism 5 is arranged on the table 10 and is located downstream of the first sewing mechanism 6 along the conveying direction of the gauze, and is used for cutting the cloth after the hemming and sewing by the first sewing mechanism 6. At this time, the gauze is cut into pieces. At this time, both the left and right sides of each piece of gauze are open, and each piece of gauze contains an implanted chip.

[0058] As Figures 13 to 15 shown in the figure, the aforesaid cutting mechanism 5 includes a pair of scissors 51 and a channel slide plate 52 that cooperates with the scissors 51. The scissors 51 are installed on the scissors seat 59. The channel slide plate 52 is horizontally arranged and has a notch 521 on the side facing the scissors 51 for the scissors 51 to perform a cutting action. The cloth to be cut can be conveyed to the corresponding cutting station above the notch 521 for the scissors 51 to cut. A detection mounting plate 53 is installed below the channel slide plate 52. The detection mounting plate 53 is fixed to the scissors seat 59. Figure 13 Taking the direction of the arrow A in the figure as the forward direction, the scissors seat 59 and the detection mounting plate 53 can reciprocate in the front-back direction under the drive of the drive mechanism.

[0059] A fixed guide rail 511 arranged front to back is installed on the base 510. A slider 512 is installed on the fixed guide rail 511. The scissors seat 59 and the detection mounting plate 53 are fixed on the slider 512. The driving output end of the driving mechanism is connected to the slider 512. In this embodiment, the driving mechanism is the second cylinder 513. The second cylinder 513 is located at the rear side of the slider 512, and the output end of the second cylinder 513 is fixedly connected to the slider 512. Driven by the second cylinder 513, the slider 512 makes a reciprocating motion back and forth, and then drives the detection mounting plate 53 and the scissors seat 59 to move back and forth. In the initial state, the fabric to be cut is located on the front side of the notch 521. As the slider 512 moves forward, the fabric to be cut enters the corresponding cutting station above the notch 521.

[0060] The middle part of the swing rod 54 is rotatably connected to the detection mounting plate 53. A torsion spring 56 is installed at the rotatable connection part in the middle of the swing rod 54. The torque of the torsion spring 56 is adjusted through the bushing 514. The upper end of the swing rod 54 extends upward out of the notch 521 and is located in front of the tip of the scissors 51. The first sensor 55 is located below the rotatable connection part of the swing rod 54. The first sensor 55 is arranged at the rear side of the swing rod 54 and close to the lower end of the swing rod 54. When the lower end of the swing rod 54 swings to the sensing position of the first sensor 55, the first sensor 55 can emit a sensing signal.

[0061] A spring mounting hole 531 is formed in the detection mounting plate 53. A fixed pin 58 is arranged in the spring mounting hole 531. The inner end of the second spring 57 is sleeved on the fixed pin 58, and the outer end of the second spring 57 abuts against the side part of the upper end of the swing rod 54. The second spring 57 is located above the rotatable connection part of the swing rod 54 and arranged at the front side of the swing rod 54. In the process of the upper end of the swing rod 54 deflecting forward, that is, in the direction away from the tip of the scissors 51, the second spring 57 is compressed to keep the swing rod 54 having a tendency to reset.

[0062] During operation, the fabric to be cut moves along Figure 13The direction indicated by arrow B passes through the channel slide plate 52, and the cloth to be cut is located on the front side of the swing rod 54. At the same time, the arrow knife 51 and the channel slide plate 52 move forward under the drive of the second cylinder 513. Since the upper end of the swing rod 54 extends upward out of the channel slide plate 52, the cloth to be cut drives the upper end of the swing rod 54 to deflect backward, and the torsion spring 56 is in an energy storage state. When the cloth to be cut enters the shearing station, the swing rod 54 resets under the action of the torsion spring 56, and the scissors 51 cut the cloth to be cut at the shearing station. After the shearing operation is completed, the arrow knife 51 and the channel slide plate 52 move backward under the drive of the second cylinder 513. At this time, if the cloth to be cut has been cut, then the swing rod 54 will not be resisted during the backward movement, that is, the swing rod 54 will not deflect. If the cloth to be cut is not cut, then the swing rod 54 will be blocked by the cloth to be cut during the backward movement, that is, the upper end of the swing rod 54 is hooked by the cloth to be cut. As Figure 14 shown, the upper end of the swing rod 54 can only deflect forward, the second spring 57 is compressed, the lower end of the swing rod 54 deflects backward and is sensed by the first sensor 55, and the first sensor 55 then sends a corresponding signal to the controller. The controller controls the equipment to stop. After the uncut cloth is taken away, the swing rod 54 resets under the action of the second spring 57, and the arrow knife 51 and the channel slide plate 52 retract backward to their original initial positions.

[0063] The deflection mechanism acts on the presser foot mechanism 3 to drive the pressing member 36 to rotate 90° on the table surface 10 of the workbench 1, and then arrange the openings on the left and right sides of the gauze in the front and back. As Figures 5 to 9 shown, the deflection mechanism includes a transmission rod 37 and a bushing 38. The inside of the fixing member 39 is provided with a first channel 391 communicating with the cavity 310 and a second channel 392 for the transmission rod 37 to pass through. Both the first channel 391 and the second channel 392 extend vertically. The side wall of the sleeve 31 is provided with a through groove 311 communicating with the first channel 391 and extending along the up and down direction. The transmission rod 37 can be located in the through groove 311 and is arranged to be able to move up and down relative to the sleeve 31. A first sliding member 370 passing through the through groove 311 is relatively fixed on the side wall of the transmission rod 37, and the first sliding member 370 is in the form of a roller. As Figures 6 to 9 shown, the elastic member acts on the connecting rod 32 and makes the connecting rod 32 always have a tendency to move downward, and then makes the pressing member 36 press the folded double-layer gauze on the table surface 10 of the workbench 1. In this embodiment, as Figures 4 to 7 shown, the elastic member is a first spring 34 located in the first channel 391. The top of the first channel 391 is provided with a cover plate 393 for blocking its top. The upper end of the first spring 34 abuts against the cover plate 393, and the lower end of the first spring 34 abuts against the upper part of the connecting rod 32.

[0064] As Figures 4 to 7As shown, a guide member 323 is provided on the side wall of the above-mentioned connecting rod 32, and the guide member is in the form of a roller. The bushing 38 is disposed in the upper channel 3101 of the cavity 310 and sleeved around the connecting rod 32. A guide groove 381 extending along the length direction of the connecting rod 32 and guidingly cooperating with the guide member 323 is formed on the inner peripheral wall of the bushing 38. A chute 382 slidably cooperating with the first slider 370 is formed on the outer peripheral wall of the bushing 38, and at least a part of the chute 382 spirally extends downward. In this embodiment, as Figure 12 shown, the chute 382 includes a first extension groove 3821, a second extension groove 3822, and a third extension groove 3823 that are connected in sequence from top to bottom. Both the first extension groove 3821 and the third extension groove 3823 extend vertically and are arranged at intervals along the circumferential direction of the bushing 38. The second extension groove 3822 gradually extends obliquely downward toward the third extension groove 3823 from top to bottom, so the second extension groove 3822 is the part of the chute 382 that spirally extends downward. When the transmission rod 37 moves up and down, it can drive the bushing 38 and the connecting rod 32 to rotate relative to the sleeve 31, and then drive the pressing member 36 to deflect the fabric. For example, when the transmission rod 37 moves upward, it drives the pressing member to rotate counterclockwise by 90 degrees through the cooperation with the sleeve and the connecting rod. At this time, the first slider 370 is located in the first extension groove 3821. Specifically, refer to 8 and Figure 9 shown; when the transmission rod moves downward, it drives the pressing member to rotate clockwise by 90 degrees through the cooperation with the sleeve and the connecting rod. At this time, the first slider 370 is located in the second extension groove 3822. Specifically, refer to Figure 6 and Figure 7 shown. Thus, when the connecting rod 32 is in the state of rotating 90 degrees, the first slider 370 is located in the first extension groove 3821 or the second extension groove 3822.

[0065] A driving portion is provided on the fixing plate 7 that acts on the transmission rod 37 to move the transmission rod 37 up and down when the conveyor belt is in a moving state. As Figures 3 to 5As shown in the figure, the above-mentioned driving part is an annular slideway 70 formed on the fixed plate 7, surrounding the output shaft of the second motor 41 and the connecting shaft 43 and being annular. The upper end of the transmission rod 37 is provided with a first roller 371 located above the second channel 392, and the first roller 371 is in sliding fit with the aforementioned annular slideway 70. The part of the annular slideway 70 located below the connecting shaft 43 and extending along the left-right direction is defined as the lower slideway 71. The lower slideway 71 includes a first slide segment 711, a second slide segment 712, and a third slide segment 713 that are sequentially connected along the conveying direction of the fabric. Among them, both the first slide segment 711 and the third slide segment 713 extend along the left-right direction, and the first slide segment 711 and the third slide segment 713 are arranged in a staggered manner and are located below the third slide segment 713. The second slide segment 712 gradually slopes upward along the conveying direction of the fabric and is located at the position corresponding to between the second sewing mechanism 8 and the cutting mechanism 5. Specifically, the fixed plate 7 includes an arc portion 72, a main body portion 73 with an annular runway cross-section, and a connecting plate 74 located below the main body portion 73. The outer peripheral wall of the fixed plate 7 as a whole has a cam structure. The outer peripheral wall of the aforementioned main body portion 73 includes a first arc segment 731 and a second arc segment 732 arranged at intervals left and right, and an upper slide segment 733 and a lower slide segment 734 that are both located between the first arc segment 731 and the second arc segment 732 and extend along the left-right direction. The lower slide segment 734 is located below the upper slide segment 733. The arc portion 72 is formed on the outer wall surfaces of the second arc segment 732 and the lower slide segment 734 and is arranged in a staggered manner with the connecting plate 74. The part of the annular slideway 70 except for the third slide segment 713 and the second slide segment 712 is located on the outer peripheral wall of the main body portion 73. The first slide segment 711 is located on the bottom wall of the arc portion 72. The connecting plate 74 is partially located below the arc portion 72, and a second slide segment 712 is formed between the connecting plate 74 and the arc portion 72, and a third slide segment 713 is formed between the connecting plate 74 and the main body portion 73.

[0066] Under the action of the elastic member, the pressing member 36 presses the gauze with the chip inside against the tabletop. After the cutting mechanism 8 cuts the gauze into pieces, each piece of gauze contains a chip inside. After the cutting mechanism finishes working, at this time, the first roller 371 at the upper end of the transmission rod 37 moves along the first slide segment 711. Under the conveying of the conveying mechanism, the first roller 371 of the transmission rod 37 moves into the third slide segment 713 after passing through the first slide segment 711 and the second slide segment 712. When it moves into the third slide segment 713, at this time, the first sliding member 370 on the transmission rod 37 enters the first extension groove 3821 through the second extension groove 3822, driving the shaft sleeve and the connecting rod 32 to rotate 90 degrees relative to the sleeve 31. At this time, the gauze with the chip inside is arranged front and back with both sides open.

[0067] As Figure 1As shown in the figure, two sets of second sewing mechanisms 8 are arranged on the tabletop 10 of the workbench 1, and are respectively located on the left and right sides of the pressing member 36, so as to perform edge sewing on the gauze openings on the corresponding sides. Along the conveying direction of the gauze, the second sewing mechanism 8 is located downstream of the cutting mechanism 5. Each set of second sewing mechanism 8 corresponds to a thread cutting mechanism 02, so there are two sets of thread cutting mechanisms 02, which are arranged at intervals in the front-rear direction. Along the conveying direction of the gauze, the thread cutting mechanism 02 is located downstream of the corresponding second sewing mechanism 8, so the thread cutting mechanism 02 cuts the thread after the edge sewing of the second sewing mechanism, and finally makes the finished product of the gauze bag with a chip inside. The thread cutting mechanism adopts the structure in the prior art and will not be described in detail in this embodiment.

[0068] As Figures 16 to 18 shown in the figure, the waste product screening mechanism is installed at the finished product output end of the sewing equipment to screen the waste products sewn by the sewing equipment. The waste product screening mechanism specifically includes a bracket 91. The bracket 91 includes a first support plate 911 and a second support plate 912 arranged oppositely. A first pulley 981 and a second pulley 982 are installed between the first support plate 911 and the second support plate 912. A conveyor belt 93 is arranged between the first support plate 911 and the second support plate 912 and is installed on the first pulley 981 and the second pulley 982. Partition plates 931 are arranged at intervals along the conveying direction on the conveyor belt 93. The second motor 92 is installed outside the first support plate 911. The first pulley 981 is installed on the output shaft of the second motor 92. The conveyor belt 93 moves under the drive of the second motor 92. The products to be screened after sewing are conveyed to the conveyor belt 93 one by one. One product to be screened is placed between adjacent partition plates 931. In this embodiment, the product to be screened is a sewn package implanted with a metal chip.

[0069] An air inlet 913 is opened on the first support plate 911, and a waste product blowing outlet 914 corresponding to the air inlet 913 is opened on the second support plate 912. Both the air inlet 913 and the waste product blowing outlet 914 are arranged above the conveyor belt 93. A blowing component 94 for blowing air towards the air inlet 913 is installed on the first support plate 911. A second sensor 95 is installed on the first support plate 911. The sensing head of the second sensor 95 faces the transmission channel of the conveyor belt 93. The signal input end of a controller (not shown in the drawing) is electrically connected to the second sensor 95, and the signal output end of the controller is electrically connected to the blowing component 94. During the conveying process of the conveyor belt 93, the products to be screened will pass through the sensing area of the second sensor 95 one by one. When a genuine product passes through the sensing area, the blowing component 94 does not perform a blowing action, and the genuine product passes through the conveyor belt 93 smoothly. When a waste product passes through the sensing area, the sensor sends a signal to the controller. After receiving the signal, the controller controls the blowing component 94 to blow air, so as to blow the waste product out from the waste product blowing outlet 914.

[0070] To prevent the waste products from being blown away on the conveyor belt 93 by the air blowing assembly 94, air guiding plates for guiding the waste products on the conveyor belt 93 to be blown out from the waste product blowing outlet 914 are further installed on the first support plate 911 and the second support plate 912. In this embodiment, the air guiding plates include an upper air guiding plate 961 and a lower air guiding plate 962. The upper air guiding plate 961 is installed at the upper edge of the air inlet 913 and the waste product blowing outlet 914. The upper air guiding plate 961 is located above the conveyor belt 93 and forms an air blowing channel 97 with the conveyor belt 93, and ensures that the partition plate 931 can pass through smoothly. Moreover, the upper air guiding plate 961 has an upper extending portion 963 extending outward beyond the upper edge of the waste product blowing outlet 914. The lower air guiding plate 962 is installed at the lower edge of the air inlet 913 and the waste product blowing outlet 914. Moreover, the lower air guiding plate 962 has a lower extending portion 964 extending outward beyond the lower edge of the waste product blowing outlet 914. Both the upper extending portion 963 and the lower extending portion 964 are inclined downward. During operation, a waste product collection bag is placed below the waste product blowing outlet 914, and the waste products can fall into the waste product collection bag smoothly.
