The present invention belongs to the technical field of suture production, and in particular, relates to an integrated injection molding device for medical sutures with barbs, including a softening component, a cutting component, and a shaping component, etc. The softening component is used to soften a flat wire, the cutting component is used to stagger barbs on both sides of the softened flat wire, and the shaping component is used to round and shape the flat wire that has been processed with barbs. The present invention heats and softens the flat wire by means of a softening component, so that the cutter in the cutting component can more easily cut barbs on the wire, and the strength requirements of the cutter are relatively low. At the same time, since the cutter cuts and processes barbs on the softened wire, the first electric push rod that drives the cutter only needs to consume less electrical energy and provide less power to achieve effective cutting of the wire by the cutter, thereby minimizing the volume of the first electric push rod as a driving structure, and effectively reducing the equipment cost on the basis of ensuring the demand.
Description
Technical Field
The invention belongs to the technical field of suture production, and particularly relates to injection molding integrated equipment for a medical suture with barbs.
Background
The barbed medical suture can achieve the effect of no need of knotting after finishing wound suturing, and the barbed suture is widely used in hospitals.
In the published patent application 202410752866.1, the barbed suture is processed by passing through a thin round wire of an extruder and then directly processing the barbs on the thin round wire. Because the processing location of wire rod is inaccurate, the processing degree of difficulty is great, so in order to reduce the degree of difficulty of barb processing on the wire rod, need flatten circular wire rod into the wire rod that the cross section is oval earlier, cut out the barb on the thinner border in both sides of flat wire rod with cutting tool again. Because of the high hardness and strength of the wire, the cutting tool is required to be sharp and strong enough, and the cutting driving structure is required to provide enough power for the cutting tool, so that the whole volume of the device is large.
In addition, since the barbs are formed by processing flattened wires, as shown in fig. 23, the difference between bending resistances of the suture formed by the flattened wires after the barbs are processed in the thin direction and the thick direction is large, so that the suture cannot be easily routed as required in the process of suturing the wound, and secondary damage is caused by the formation of severe traction to the wound in different degrees.
The invention designs energy-saving reheating equipment, which realizes softening of wires, improves barb processing structures for the softened wires, and increases structures for rounding and shaping flat suture lines which are still in a softened state after barb processing is finished so as to solve the problems.

According to the invention, the shaping component is used for carrying out rounding shaping on the flat wire which is processed by the barb by the cutting component and still in a softened state, so that the cross section of the finally formed suture is close to a circle, and further, the bending resistance of the finally formed barbed suture in any direction is uniform, the suture can be flexibly routed to carry out wound suturing according to the needs in the use process, the use experience of the suture is improved, and the secondary wound formed on the wound due to the pulling of the suture in the wound suturing process is avoided or reduced. The heat recovery component can recover the heat carried by the barbed suture line which is rounded and shaped into the first cylinder shell of the softening component, and the recovered heat entering the first cylinder shell slowly moves to heat the outer side of the electric heating cylinder to the greatest extent, so that the temperature difference between the inner side and the outer side of the electric heating cylinder is reduced, the heating efficiency of the electric heating cylinder for effectively heating the wire moving from the inner side of the electric heating cylinder is improved, and the energy consumption of the electric heating cylinder in the process of heating and softening the wire is reduced.

According to the invention, the flat wire 110 is heated and softened through the softening assembly 500, so that the cutter 607 in the cutting assembly 600 can cut barbs 112 on the wire 110 more easily, the strength requirement on the cutter 607 is lower, meanwhile, as the cutter 607 cuts the softened wire 110 to process the barbs 112, the first electric push rod 603 for driving the cutter 607 can effectively cut the wire 110 by consuming less electric energy to provide less power, and the volume of the first electric push rod 603 serving as a driving structure is reduced to the greatest extent, so that the equipment cost is effectively reduced on the basis of ensuring the requirement. The shaping component 700 is used for carrying out approximate rounding shaping on the flat wire 110 which is processed by the barb 112 and still in a softened state by the cutting component 600, so that the cross section of the finally formed suture is approximate to a circle, further, the bending resistance of the finally formed suture with the barb 112 in any direction is uniform, the suture can be flexibly routed to carry out wound suturing according to the requirement in the use process, the use experience of the suture is improved, and the secondary wound formed on the wound due to the pulling of the suture in the process of suturing the wound by the suture is avoided or reduced. The heat recovery assembly 800 in the invention can recover the heat carried by the suture thread with barbs 112 after being rounded and shaped into the first cylinder shell 502 of the softening assembly 500, and the recovered heat entering the first cylinder shell 502 slowly moves to heat the outer side of the electric heating cylinder 507 to the greatest extent, so that the temperature difference between the inner side and the outer side of the electric heating cylinder 507 is reduced, the heating efficiency of the electric heating cylinder 507 for effectively heating the wire 110 moving from the inner side of the electric heating cylinder 507 is improved, and the energy consumption of the electric heating cylinder 507 in the process of heating and softening the wire 110 is reduced. In the present invention, the second cylinder shell 801 of the heat recovery assembly 800 has a smaller volume and two groups of spoilers 806 are symmetrically distributed therein, so that the air entering from the second air inlet pipe 802 is effectively disturbed by the spoilers 806 to form turbulence, and the air forming turbulence has higher and faster temperature rise under the conduction of the heat carried by the suture line moving in the second cylinder shell 801, thereby improving the heat recovery efficiency of the softening assembly 500.
The operation flow of the invention is as follows:
In the initial state, flat wires 110 are wound on the winding wheel 203 of the winding and unwinding assembly 200 on the side of the softening assembly 500, the flat wires 110 sequentially pass through the traction assembly 300, the soft switching assembly, the cutting assembly 600, the shaping assembly 700 and the shaping side traction assembly 300 on the corresponding side to reach the winding wheel 203 of the final winding and unwinding assembly 200 for winding, the first clamping wheel 303 in the two traction assemblies 300 presses the wires 110 against the grooves on the rim of the corresponding second clamping wheel 305 under the action of the corresponding return springs, the return springs in the telescopic rod 900 are in a compressed state, the horizontal distance of the two cutters 607 in the cutting assembly 600 along the radial direction of the first cylinder shell 502 is the largest, the barbs 607 in the state do not interfere with the wires 110, the round rod 604 in the cutting assembly 600 is positioned at the end of the corresponding guide groove 103 farthest from the wires 110, the return springs in the telescopic rod 900 connected with the third gear 601 are in a compressed state, and the three clamping blocks 701 in the shaping assembly 700 have enough spacing with the wires 110 and do not interfere with the barbs 112 on the wires 110.
When the flat wire 110 needs to be processed by the barb 112, the electric heating cylinder 507 in the softening assembly 500 is started, the electric heating cylinder 507 heats and rapidly heats the wire 110, when the wire 110 in the electric heating cylinder 507 is softened by being added to a certain temperature, the first motors 204 in the two winding and unwinding assemblies 200 and the second motors 306 in the two traction assemblies 300 are started, the two first motors 204 in the two winding and unwinding assemblies 200 respectively drive the corresponding winding wheels 203 to rotate through the corresponding first rotating shafts 202, the winding wheels 203 in the winding and unwinding assemblies 200 on the softening assembly 500 side loosen the flat wire 110 wound on the winding wheels 203, and the winding wheels 203 in the winding and unwinding assemblies 200 on the heat recovery assembly 800 side wind the wire 110.
The second motor 306 in the drawing assembly 300 on the softening assembly 500 side drives the corresponding second clamping wheel 305 to rotate through the corresponding second rotating shaft 304, the second clamping wheel 305 drives the corresponding first clamping wheel 303 to rotate through the flat wire 110, the first clamping wheel 303 and the second clamping wheel 305 clamp the wire 110 together and move the wire 110 into the softening assembly 500, meanwhile, the second rotating shaft 304 in the drawing assembly 300 on the softening assembly 500 side drives the second clamping wheel 305 and the first clamping wheel 303 in the drawing assembly 300 on the heat recovery assembly 800 side to rotate through the corresponding first gear 401, the second gear 402, the third rotating shaft 403, the second gear 402 and the first gear 401, and the rotation linear speeds of the first clamping wheel 303 and the second clamping wheel 305 in the two drawing assemblies 300 are equal, and the drawing assembly 300 on the heat recovery assembly 800 side draws the wire 110 towards the corresponding winding and unwinding assembly 200.
The two traction assemblies 300 clamp the constant-speed traction wire 110 at two ends of the softened portion of the wire 110 to move towards the shaping assembly 700, so that the softened portion of the wire 110 is prevented from being pulled to deform, and the diameter of the wire 110 after the suture is finally formed is uniform.
In the process of heating the wire 110 by the electric heating cylinder 507, the heat insulation layer 113 outside the electric heating cylinder 507 can effectively ensure that the temperature of the wire 110 changes little.
As shown in fig. 15, when the softened portion of the wire 110 moves into the glass cover 108 and reaches between the two cutters 607 in the cutting assembly 600 under the driving of the two traction assemblies 300, the operation of the first motor 204 and the second motor 306 is stopped, so that the wire 110 moves and winding and unwinding are stopped, then the first electric push rod 603 in the cutting assembly 600 is started, the first electric push rod 603 drives the corresponding side third gear 601 to rotate through the corresponding telescopic rod 900, the third gear 601 drives the other side third gear 601 to rotate through the two fourth gears 602, the rotation directions of the two third gears 601 are opposite, the swinging directions of the two telescopic rods 900 are opposite, the two telescopic rods 900 respectively drive the corresponding round rods 604 to move in the guide grooves 103 to the wire 110, the round rods 604 drive the corresponding cutters 607 to move to the limit of the guide grooves 103 to be close to the end of the guide arc 104 of the wire 110, and the two cutters 607 cut the cut grooves 111 on the wire 110 at two sides of the softened flat wire 110 in a state of small included angle with the axial direction of the wire 110, and the barbs 112 are formed.
When the depth of the incision 111 reaches the requirement, the first motor 204 and the second motor 306 are started to drive the two pulling assemblies 300 and the two winding assemblies 200 to operate by a small extent, so that the wire 110 moves by a small extent, the barb 112 which is just cut out swings reversely by a small extent under the action of the second arc surface 611 which is not separated from the outer side of the cutter 607 of the incision 111, and the portion of the barb 112 which is separated from the surface of the wire 110 protrudes out more downward and forms a substantially effective barb 112.
Then, the first electric push rod 603 is started, the first electric push rod 603 drives the telescopic rods 900 on the two third gears 601 to swing back and reset through some transmission, the two telescopic rods 900 drive the two cutters 607 to swing back and reset and separate from the cutting groove 111 and the wire 110, and the reset cutters 607 do not interfere with the barbs 112 on the moving wire 110.
During the swinging process of the two telescopic rods 900 in the cutting assembly 600, the round rods 604 are matched with the guide grooves 103, the two telescopic rods 900 can expand and contract correspondingly, and the first electric push rod 603 swings adaptively correspondingly.
After the two cutters 607 are reset to be separated from the cutting grooves 111 on the wire 110 and far away from the barbs 112, the two first motors 204 in the two winding and unwinding assemblies 200 and the second motors 306 in the traction assemblies 300 are continuously started, the two winding and unwinding assemblies 200 and the two traction assemblies 300 drive the wire 110 to continuously move by a certain amplitude which is twice the distance between the adjacent barbs 112, so that three clamping blocks 701 in the shaping assembly 700 are respectively opposite to the parts between the adjacent cutting grooves 111 on two sides of the wire 110.
Then, as shown in fig. 17 and 20, the second electric push rod 708 is started, the second electric push rod 708 drives the clamping blocks 701 on one side to move along the radial direction of the wire 110 through the sliding seat 705 connected with the second electric push rod 708, the clamping blocks 701 on one side drive the two clamping blocks 701 on the other side to move along the radial direction of the wire 110 at the same speed through the corresponding racks 706 and the corresponding racks 706 of the two fifth gears 707 and the two clamping blocks 701 on the other side, after the two clamping blocks 701 on the two sides are in radial butt joint, the semicircular grooves 702 on the inner walls of the two clamping blocks 701 on the two sides form complete circular grooves, and the positions between the adjacent cutting grooves 111 on the flat wire 110 with barbs 112 are clamped to be approximate to a circular shape.
During the movement of the softened portion of the wire 110 from the softening assembly 500 to the shaping assembly 700, the double-layer glass cover 108 is wrapped to effectively reduce the heat dissipation of the softened portion and maintain the softened state, which is beneficial for the cutting assembly 600 to shape the wire 110 in a flat-to-round shape of the wire 110 by the cutting and shaping assembly 700.
When the flat wire 110 in the softened state passes through the shaping assembly 700, the second electric push rod 708 is started, and the second electric push rod 708 drives the three clamping blocks to slide back and reset through a series of transmission and separate from the wire 110.
Then, the two winding and unwinding assemblies 200 and the traction assembly 300 are started again to drive the wire 110 to continue to move by a certain extent, the suture thread which completes the circular shaping and shaping still carries more heat to reach the heat recovery assembly 800, when the shaped wire 110 partially enters the second cylinder shell 801, air is blown into the second cylinder shell 801 through the second air inlet pipe 802, the air entering the second cylinder shell 801 forms turbulence under the action of the spoiler 806, the formed turbulence sends the heat carried on the suture thread into the first cylinder shell 502 of the softening assembly 500 through the first air inlet pipe 503, the air flow in the first cylinder shell 502 slowly flows due to the existence of the air outlet pipe 504, the flowing speed is smaller than 0.1m/s, the temperature rise of the outer environment of the electric heating cylinder 507 is increased, the temperature difference inside and outside the electric heating cylinder 507 is reduced, the heating efficiency of the electric heating cylinder 507 on the wire 110 in the electric heating cylinder 507 is effectively improved, and the energy consumption is reduced.
In the moving process of the wire 110, the gap between the wire 110 and the wire inlet sleeve 505 is extremely small because the wire 110 is not softened and is in a harder state, the gap between the wire 110 and the wire outlet sleeve 506 is relatively large because the wire 110 is in a softened state, scratch deformation of the wire 110 caused by small gap between the wire 110 and the wire outlet sleeve 506 is avoided, and deformation of the wire 110 caused by scratch of the wire 110 by the first wire outlet 114 and the second wire inlet 801 of the first wire outlet 114 and the second wire inlet 804 of the second wire inlet 801 of the glass cover 108 is avoided in the process that the wire 110 passes through the first wire outlet 114 and the wire inlet 804 of the second wire inlet 801 of the glass cover 108.
