In an embodiment of the present invention, the extruder 10 may be used for extruding an indwelling needle tube, and since the extruder 10 is a prior art, the detailed structure of the extruder 10 will not be described in detail herein, and the working principle of the extruder 10 in the prior art can be referred to specifically. The drawing machine 20 may be used to draw the remaining needle tube extruded by the extruder 10 so as to convey the remaining needle tube to the cutter 30. Wherein, this tractor 20 can pull the needle pipe of keeping somewhere through the track of locating on the conveying chain, also can pull the needle pipe of keeping somewhere through two matched with conveying rollers that the interval set up from top to bottom, and this application does not do the restriction to concrete type to tractor 20, can realize pulling the needle pipe of keeping somewhere can. The cutting machine 30 can cut the remaining needle tube drawn by the drawing machine 20 to form the remaining needle tube with a predetermined length. The cutting machine 30 may include a cutting blade capable of being lifted, and when the indwelling needle tube is pulled in place, the cutting blade is driven by a driving cylinder to descend to cut the indwelling needle tube. The needle tube conveying line 40 can be used for receiving the remaining needle tubes cut by the cutting machine 30 and conveying the remaining needle tubes into the temporary storage box 50 for temporary storage. Specifically, the first transporting section 41 receives the indwelling needle tube cut by the cutter 30, and transports the indwelling needle tube in the axial direction parallel to the transporting direction of the first transporting section 41. When the needle tubes are conveyed to the second conveying section 43, the conveying direction of the second conveying section 43 is perpendicular to the direction of the first conveying section 41, so that the placement state of the indwelling needle tubes can be changed for conveying, that is, when the indwelling needle tubes are conveyed on the second conveying section 43, the axial direction of the indwelling needle tubes is perpendicular to the conveying direction of the second conveying section 43, so that the indwelling needle tubes can fall into the temporary storage box 50 better in the following process. The first conveying section 41 and the second conveying section may be both belt conveying and may also be conveying rollers conveying, and the specific conveying type of the first conveying section 41 and the second conveying section 43 is not limited in this application. The temporary storage box 50 can be used for carrying out temporary storage on the remaining needle tubes conveyed by the second conveying section 43, and performing corresponding counting through the photoelectric sensing counter 51. Since the photo-sensing counter 51 is a conventional one, the detailed structure of the photo-sensing counter 51 will not be described in detail herein. The first driving member 61 of the plugging assembly 60 can drive the plugging plate 63 to move to open the needle tube blanking opening 53 at the bottom of the temporary storage box 50 when the photoelectric sensing technology on the temporary storage box 50 detects that a preset number of remaining needle tubes are received, so that the preset number can directly drop into the collecting box 70 below. Then, the worker directly packages the collecting box 70, so that the condition that the remaining needle tubes are manually packed one by one can be avoided. The first driving member 61 may drive a cylinder, or may be a linear motor.

When the production equipment for the indwelling needle tube provided by the technical scheme of the invention is used, the indwelling needle tube can be extruded and molded after rubber materials are added through the extruder 10. The remaining needle tube formed by the extruder 10 can be drawn by the drawing machine 20 to be guided to the cutting machine 30 to be cut by the cutting machine 30, thereby forming a remaining needle tube with a preset length. The remaining needle tubes cut by the cutting machine 30 can be received by the first conveying section 41 of the needle tube conveying line 40 and conveyed to the second conveying section 43. Because the second conveying section 43 is perpendicular to the first conveying section 41, the axial direction of the indwelling needle tube is parallel to the conveying direction of the first conveying section 41 when the indwelling needle tube is conveyed on the first conveying section 41, and the axial direction of the indwelling needle tube is perpendicular to the conveying direction of the second conveying section 43 when the indwelling needle tube is conveyed on the second conveying section 43, so that the indwelling needle tube can be conveniently and orderly dropped into the temporary storage box 50 for preliminary collection. Meanwhile, since the sidewall of the temporary storage box 50 is provided with the photo-electric sensing counter 51, the number of indwelling needle tubes that have fallen into the temporary storage box 50 can be detected by the photo-electric sensing counter 51. When it is detected that the temporary storage box 50 receives a predetermined number of indwelling needle tubes, the number signal is transmitted to the first driving member 61 of the plugging member 60, the first driving member 61 opens the drop port of the temporary storage box 50, so that the indwelling needle tubes in the temporary storage box 50 can further fall into the collection box 70, and then the collection box 70 is directly sealed by the worker. Consequently, the needle tubing production facility that keeps somewhere in this scheme degree of automation is higher, can carry out quantitative vanning to keeping somewhere the needle tubing and collect for follow-up needs the workman manually to arrange it in order, thereby reduced workman's intensity of labour.

Referring to fig. 5 to 7, in an embodiment of the present invention, the temporary storage box 50 includes three side plates 55, an inclined plate 57 and a bottom plate 59, wherein the three side plates 55 are connected in sequence and are vertically disposed; the inclined plate 57 is connected to two side plates 55 which are oppositely arranged in the three side plates 55, the distance between the inclined plate 57 and the side plate 55 which is opposite to the inclined plate 57 is gradually reduced from top to bottom, the inclined plate 57 is used for receiving the remaining needle tubes conveyed by the second conveying section 43, and the lower ends of the inclined plate 57 and the lower ends of the three side plates 55 are enclosed to form a needle tube blanking port 53; the bottom plate 59 is connected to one of the two side plates 55 arranged oppositely in the three side plates 55 and extends in a direction away from the other side plate; the photoelectric sensing counter 51 is provided on the upper end of the side plate 55 provided to face the inclined plate 57 among the three side plates 55, and the first driving member 61 is provided on the lower surface of the bottom plate 59.

In the present embodiment, the temporary storage box 50 is enclosed by three side plates 55 and an inclined plate 57 to form an internal space, so that one of four side walls of the temporary storage box 50 is inclined and the other three are vertical. The lower end of the inclined plate 57 and the lower ends of the three side plates 55 enclose a needle tube drop port 53, and the lower end of the temporary storage box 50 may be open. At this time, the indwelling needle cannula conveyed by the second conveying section 43 is guided by the inclined side plate 55 and can be stably introduced into the temporary storage box 50. And the curb plate 55 through three vertical form can have and carry out the butt spacing to keeping somewhere the needle tubing for the ascending both ends in the axial of the needle tubing that keeps somewhere that falls into in the temporary storage case 50 can align, and pile up by the direction order of supreme down, thereby improved the regularity that the needle tubing that keeps somewhere was settled in temporary storage case 50. Then, the needle tube blanking port 53 with the open bottom can smoothly fall into the collecting box 70 below for orderly collection, so that the arrangement state of the remaining needle can be further adjusted without manpower, and the labor intensity of workers is further reduced. The bottom plate 59 is connected to one of the two side plates 55 of the three side plates 55, which are disposed opposite to each other, and extends in a direction away from the other side plate, so that it can give a mounting position for the plugging member 60 to facilitate the mounting arrangement of the package member. Meanwhile, the bottom plate 59 will not block the blanking from the needle tube blanking opening 53. In addition, the present invention is not limited to this, and in other embodiments, the temporary storage box 50 may have a square structure or a rectangular structure.

Referring to fig. 7 and 8, in an embodiment of the present invention, L-shaped plates 591 are disposed on the lower surface of the bottom plate 59 on two opposite sides of the cover plate 63, the two L-shaped plates 591 and the bottom plate 59 enclose to form a limiting sliding slot 593, the limiting sliding slot 593 extends along the sliding direction of the cover plate 63, and the cover plate 63 is slidably embedded in the limiting sliding slot 593.

In the embodiment, the limit sliding groove 593 is formed by enclosing the L-shaped plate 591 and the bottom plate 59, so that the bearing limit effect on the cover plate 63 can be achieved, and the possibility that the cover plate 63 falls off due to large force when the needle tube blanking port 53 is blocked is reduced. Meanwhile, the cover plate 63 can be guided to slide through the limit sliding groove 593, so that the cover plate can only slide along the extending direction of the limit sliding groove 593, and the needle tube blanking port 53 can be plugged or opened accurately.

Referring to fig. 7 and 8, in an embodiment of the present invention, the bottom surface of the bottom plate 59 and the wall surface of the L-shaped plate 591 opposite to the bottom plate 59 are respectively provided with a plurality of balls 595, the balls 595 are sequentially arranged on the bottom plate 59 and the L-shaped plate 591 at intervals along the extending direction of the limiting sliding groove 593, and the cover plate 63 abuts between the bottom plate 59 and the balls 595 on the L-shaped plate 591.

In the present embodiment, the cover plate 63 is brought into contact with the plurality of balls 595, so that the cover plate 63 is in rolling friction when sliding in the stopper slide groove 593. At this time, the friction force applied to the cover plate 63 can be greatly reduced, thereby facilitating the driving of the cover plate 63 by the first driving member 61. Moreover, the arrangement reduces the wear of the cover plate 63 during sliding as much as possible, thereby advantageously extending the service life of the cover plate 63.

Referring to fig. 7, in an embodiment of the present invention, the number of the bottom plates 59 is two, the two bottom plates 59 are respectively connected to the two side plates 55 oppositely disposed among the three side plates 55, the number of the plugging assemblies 60 is two, and each plugging assembly 60 is disposed on one bottom plate 59; two first driving pieces 61 in two plugging assemblies 60 drive two plugging plates 63 to be away from or close to each other respectively to open or plug needle tube blanking opening 53, and magnets 631 attracting each other are embedded on the opposite surfaces of the two plugging plates 63, so that the two plugging plates 63 are magnetically attracted and fixed when being close to each other and abutted.

In this embodiment, two first driving members 61 in two plugging assemblies 60 respectively drive two plugging plates 63 to approach each other to plug the needle tube blanking opening 53, so that the sliding strokes of the two plugging plates 63 can be set to be relatively short, thereby facilitating the rapid plugging of the needle tube blanking opening 53. Meanwhile, the cover plate 63 can be set relatively short in the sliding direction, so that when the indwelling needle tube in the temporary storage box 50 is supported, the possibility of deformation is reduced and the support is more stable. In addition, the remaining needle tubes in the temporary storage box 50 are simply supported at the two ends in the axial direction of the remaining needle tubes and fall into the collection box 70 below when the two cover plates 63 are driven to move away from each other by the first driving members 61 connected to the two cover plates, so that the remaining needle tubes can be kept flat and fall into the collection box 70 for collection.

In this embodiment, when the photo-electric sensing counter 51 detects that the temporary storage box 50 collects a preset number of remaining needle tubes, the number in place signal may also be transmitted to the second driving member 432, so that the second driving member 432 drives the blocking plate 433 to block the remaining needle tubes subsequently conveyed by the second conveying section 43, thereby ensuring that no subsequent remaining needle tubes fall into the collection box 70 during the process of opening the needle tube discharge port 53 of the temporary storage box 50 by driving the sealing cover plate 63 to move by the first driving member 61 of the sealing assembly 60, thereby ensuring that each collection box 70 can accurately collect a fixed amount of remaining needle tubes. After all the remaining needle tubes in the temporary storage box 50 fall into the collection box 70, the first driving member 61 of the plugging member 60 drives the capping plate 63 to reset and plugs the needle tube discharge port 53 again. The photo-sensitive counter 51 can then be reset to be ready again for counting operations. The second driving member 432 of the blocking assembly 431 drives the blocking plate 433 to reset, so that the remaining needle cannula conveyed by the second conveying section 43 can continue to fall into the temporary storage box 50. The second driving member 432 may be a driving cylinder, and is disposed above the second conveying section 43, and then the driving blocking plate 433 is lowered to block the indwelling needle.

At this time, after the push plate 439 pushes the previous indwelling needle tube to the second conveying section 43, the lifting driving member 437 drives the horizontal driving member 438 and the push plate 439 to be lifted by a certain height, and then the horizontal driving member 438 drives the push plate 439 to be reset to the initial position, so that the indwelling needle subsequently transferred to the bearing platform 434 by the second conveying section 43 is not driven in the resetting process of the push plate 439, and the pushing assembly 435 is ensured to push out the indwelling needle tube transferred from the first conveying section 41 to the second conveying section 43 orderly and stably. The lifting driving member 437 and the horizontal driving member 438 may be driving cylinders or linear motors.

Referring to fig. 1 and 10, in an embodiment of the present invention, the remaining needle tube producing apparatus further includes a carton forming machine 80 and a box conveying line 90, the carton forming machine 80 is used for forming the collecting box 70; one end of the box conveying line 90 is communicated with the carton forming machine 80 to receive the collecting box 70 formed by the carton forming machine 80, and part of the conveying section of the box conveying line 90 is positioned below the needle tube blanking port 53.

In this embodiment, the collection box 70 can be formed by the carton forming machine 80, and the collection box 70 formed by the carton forming machine 80 can be directly conveyed to the lower part of the needle tube blanking port 53 by the box conveying line 90. Therefore, the collection box 70 is not required to be manually conveyed to the lower part of the needle tube blanking port 53 for receiving the remaining needle tube, and is not required to be manually moved away after receiving, so that the labor intensity of workers is further reduced. Since the carton forming machine 80 is a conventional art, the detailed structure of the carton forming machine 80 will not be described in detail herein. And the case transfer line 90 may be transferred using a transfer roller so that the collection case 70 can be stably supported during the transfer thereof.

In an embodiment of the present invention, the box conveying line 90 is provided with a stopping assembly 91, and the stopping assembly 91 includes a fourth driving member 911 and a stopping plate 913; the stop plate 913 is connected to the fourth driver 911, and is driven by the fourth driver 911 to abut against the surface of the collection box 70 on the box conveying line 90 facing the conveying direction of the box conveying line 90, so that the collection box 70 is fixed below the needle tube blanking opening 53 in a limited manner.

In this embodiment, the fourth driver 911 of the stopping assembly 91 can drive the stopping plate 913 to move to abut against the collecting box 70 on the box conveying line 90, so that the collecting box 70 can be stably limited below the needle tube discharging opening 53, and thus, the remaining needle tubes falling in the temporary storage box 50 can be stably received. The fourth driving member 911 may be a driving cylinder, and may be disposed below the box conveying line 90, and then may abut against the blocking collection tank 70 by driving the blocking plate 913 through the box conveying line 90.
