Description

Technical Field

[0001] The invention belongs to the technical field of medical consumables, and in particular relates to a cutting device for a drip bucket of an infusion tube. Background Art

[0002] Infusion tube is a commonly used medical consumable. The various parts of the infusion tube are generally made using different processes or equipment, and then assembled into a qualified infusion tube. The drip chamber is a part of the infusion tube, and the speed of injecting the drug can be observed during the injection process.

[0003] At present, most of the processing of drip buckets adopts the blow molding method. In order to improve the processing efficiency, continuous blow molding is often used. Therefore, the drip buckets processed in this way are all strung together and need to be cut separately before they can be used. However, there are still some problems when cutting the current drip buckets: 1. When cutting the drip buckets, they are still cut one by one, and the cutting efficiency is very low. 2. After the drip bucket is blow-molded, the cooling time is short, and the material at the cutting position of the drip bucket is still in a high temperature state. When cutting, it is often difficult to cut a smooth incision at the cutting mouth due to the extrusion of the cutting knife; and the cutting position is prone to deformation. 3. The drip bucket has no internal support during processing and is easily damaged and deformed. Therefore, based on the above problems, a drip bucket cutting device with better effect suitable for continuous processing is proposed. Summary of the invention

DETAILED DESCRIPTION

[0039] In order to enable those skilled in the art to better understand the technical solution, the present invention is described in detail below in conjunction with embodiments. The description in this section is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0040] like Figure 1-9As shown, the specific scheme of this embodiment is: a cutting device for an infusion tube drip bucket, including a cutting assembly 10, the cutting assembly 10 includes a first clamping member 1001 and a second clamping member 1002 for limiting the position of the drip bucket, the first clamping member 1001 and the second clamping member 1002 are clamping molds with a receiving space in the middle, and a first knife holder 1006 is movably provided on the first clamping member 1001, and the first knife holder 1006 is connected to a first driving source that drives it to rise and fall so that the first cutter 1003 cuts the drip bucket, refer to the attached Figure 3 As shown;

[0041] Specifically, the first driving source is a driving cylinder, which is fixed on a supporting frame. The supporting frame and the drip bucket blow molding device are fixed together, and in order to cool the formed drip bucket, a turntable is provided on one side of the blow molding device to facilitate the activity of the drip bucket. After the drip bucket is cooled in the air by the turntable, it enters the first clamping member 1001 and the second clamping member 1002 for cutting; the output shaft of the driving cylinder is directly fixedly connected to the top of the first tool holder 1006, and the rear side part of the first clamping member 1001 and the guide column provided on the frame are slidingly arranged with each other, and the first clamping member 1001 and the output shaft of the driving cylinder are also connected to each other through a guide shaft, and an extrusion spring 1012 is also provided between the first clamping member 1001 and the first tool holder 1006 to limit the range of movement between the first clamping member 1001 and the first tool holder 1006, such as Figure 3 When the driving cylinder is moving downward, the first clamping member 1001 first contacts the second clamping member 1002 to clamp the drip bucket for limiting the position. During the continuous downward movement, the squeezing spring 1012 provides squeezing force to the first clamping member 1001.

[0042] The connected drip buckets are transferred to the space clamped by the first clamping member 1001 and the second clamping member 1002 and fixed therein. The first clamping member 1001 and the second clamping member 1002 are respectively provided with a plurality of first cutters 1003 and a second cutter 1004 for cutting off the drip buckets; the first cutter 1003 is fixedly arranged on the first knife holder 1006, and the second clamping member 1002 is elastically and movably provided with a second knife holder 1007 corresponding to the position of the first knife holder 1006. Specifically, the second clamping member 1002 is provided with a plurality of slide grooves for facilitating the up and down movement of the second knife holder 1007, and a spring for pulling the second knife holder 1007 to move downward is provided between the second knife holder 1007 and the slide groove wall in the slide groove, which can be referred to in the attached figure. Figure 4 The second cutter 1004 is fixedly arranged on the second cutter holder 1007. The first cutter 1003 and the second cutter 1004 have the same structure, specifically, they are in a "C" shape, which can be referred to in the attached Figure 8 ;

[0043] The lower side of the second clamping member 1002 is elastically provided with a control rod 1008. Specifically, below the control rod 1008 is a frame supporting the second clamping member 1002 and the control rod 1008. The control rod 1008 and the frame slide with each other, and a return spring for driving the control rod 1008 to return to its original position is provided between the control rod 1008 and the frame. Figure 3 The figure only indicates the existence of the spring, and the specific structure is not drawn, which does not affect the movement of the control rod 1008; the control rod 1008 is provided with a top pressure surface 1009 which can contact the second tool holder 1007 and push it to move up and down. The top pressure surface 1009 is specifically an inclined surface. The second tool holder 1007 can slide at different positions of the top pressure surface 1009. When the control rod 1008 changes to different positions, it can push the second tool holder 1007 to change its up and down position, thereby realizing the cutting control of the drip bucket cutting position.

[0044] In order to enable the first cutter 1003 and the second cutter 1004 to perform cutting movements synchronously during cutting, a guide surface 1011 is provided at one end of the control rod 1008, and the guide surface 1011 is an inclined surface. The first tool holder 1006 is provided with a push rod 1010 extending downward to contact the guide surface 1011 and push the control rod 1008 to move. Therefore, through this structure, when the cylinder drives the first tool holder 1006 to move downward, the push rod 1010 will also press the guide surface 1011 downward to drive the control rod 1008 to move. When the control rod 1008 moves, the second tool holder 1007 can be driven to drive the second cutter 1004 to cut upward. At this time, the first cutter 1003 and the second cutter 1004 cut the drip bucket synchronously up and down.

[0045] In order to ensure the integrity of the incision during cutting, air ducts 1005 are provided on both sides of the first cutter 1003 and the second cutter 1004 for blowing air to the cutting position for cooling; specifically, the air duct 1005 is a plurality of fine holes provided on the first tool holder 1006 and the second tool holder 1007, and the first tool holder 1006 and the second tool holder 1007 are connected to an air source for cooling. Through air blowing cooling, the material at the cutting position can be cooled to a harder degree, the cutting process is more crisp, and the quality of the incision is improved, thereby ensuring greater convenience in the subsequent assembly process.

[0046] like Figure 1 , 2As shown, as a preferred embodiment of the above embodiment, a feeding assembly 11 is further provided on the feeding side of the cutting assembly 10, and the feeding assembly 11 includes a belt transmission mechanism 1101 which is symmetrical up and down, and a groove for accommodating a drip bucket is provided on the conveying belt of the belt transmission mechanism 1101. Specifically, the belt transmission mechanism 1101 adopts a toothed belt transmission, which can avoid slipping and ensure that the drip bucket can be accurately transmitted to the cutting position.

[0047] like Figure 3 , 5 , 6, 7, and 9, as a preferred embodiment of the above embodiment, a core tube 12 that can be inserted into the inside of the drip bucket to be cut is movably provided on the discharge side of the cutting assembly 10, which can be referred to Fig. 9 The core tube 12 includes a straight tube portion in the middle and conical end portions at both ends, which are connected by threads. A hollow transmission box 13 is movably arranged on the core tube 12, and the transmission box 13 is sleeved on the outer side of the core tube 12. A sealing sleeve is used to seal the core tube 12 and the transmission box 13. An air inlet pipe 14 for injecting gas into the transmission box 13 is connected to the lower side of the transmission box 13;

[0048] Both ends of the core tube 12 are provided with air holes 121 connected to the inside of the core tube 12, and after the core tube 12 is inserted into the drip bucket to be tested, the injected gas enters through the air holes 121 located in the transmission box 13, and is ejected from the air holes 121 located on one side of the drip bucket. When one end of the core tube 12 is inserted into the drip bucket, the other end of the core tube 12 is mostly retracted into the transmission box 13. At this time, the air holes 121 at one end retracted in the transmission box 13 and the transmission box 13 are interconnected. Therefore, after the gas is passed into the transmission box 13, the gas will enter the core tube 12 through the air holes 121, and then be ejected into the drip bucket through the air holes 121 at the other end to cool the cutting of the drip bucket and inflate and support the drip bucket.

[0049] A driving assembly is rotatably arranged in the transmission box 13, which can drive the core tube 12 to reciprocate on the transmission box 13; the driving assembly includes a driving wheel 15 rotatably arranged in the transmission box 13, the driving wheel 15 can contact with the core tube 12 to drive the core tube 12 to reciprocate, and the driving wheel 15 is a wheel with an arc-shaped contact surface. A first gear 16 is arranged on the top of the transmission box 13, such as Figure 6 The first gear 16 is specifically rotatably set on the rotating shaft of the transmission box 13. The rotating shaft of the transmission box 13 is connected to the frame through a "U"-shaped bracket. The first gear 16 is transmission-connected to the second driving source. In this embodiment, the second driving source is a motor, and the motor is fixedly mounted on the "U"-shaped bracket; a second gear 17 meshing with the first gear 16 is set on the rotating shaft of the driving wheel 15.

[0050] The output shaft of the motor is splined with a third gear 18. Figure 5 The third gear 18 is rotatably arranged on the movable seat 19, and the movable seat 19 is connected to a third driving source that drives it to move up and down. In this embodiment, the third driving source is a driving cylinder fixedly arranged on a "U"-shaped bracket. The specific structure of the movable seat 19 is fork-shaped, such as Figure 7 When the motor is started, the third gear 18, the first gear 16, and the second gear 17 can be synchronously driven to rotate, thereby driving the driving wheel 15 to rotate, thereby driving the reciprocating movement of the core tube 12;

[0051] In order to make the driving wheel 15 contact with the core tube 12 only when the driving core tube 12 moves, an elastic member 20 that drives the driving wheel 15 to move elastically up and down is provided between the rotating shaft of the driving wheel 15 and the transmission box 13. The elastic member 20 can push the driving wheel 15 upward to lift it up, thereby preventing the driving wheel 15 and the core tube 12 from driving without a driving force. This arrangement is mainly because when the position of the rotating transmission box 13 is rotated and the direction of the core tube 12 is changed, the second gear 17 will roll on the first gear 16, thereby driving the driving wheel 15 to rotate. Therefore, in order to avoid the situation where the position of the core tube 12 and the transmission box 13 are changed, the second gear 17 will roll on the first gear 16. At the same time, the position between the core tube 12 and the transmission box 13 is still kept stable, and the driving wheel 15 and the core tube 12 are arranged to be in contact only during the driving process; on the other hand, the movable seat 19 is provided with a rotating shaft that can press the driving wheel 15 downward to make the driving wheel 15 and the core tube 12 contact and drive the driving wheel 15. The head 191 and the movable seat 19 are rotated with each other. Therefore, when the core tube 12 is driven to move, the movable seat 19 is first driven downward by the cylinder to move. At this time, the driving wheel 15 can be pressed downward by the head 191 to make it contact with the core tube 12. When the motor is started, the core tube 12 can be driven to move.

[0052] like Figure 6 As shown, as a preferred embodiment of the above embodiment, a shifting assembly for driving the core tube 12 and the transmission box 13 to swing is also provided on the lower side of the transmission box 13;

[0053] The transposition component includes a worm wheel 21 fixed to the transmission box 13, the worm wheel 21 is rotatably connected to the intake pipe 14, and a worm 22 is meshingly provided on the worm wheel 21, and the worm 22 is connected to a fourth driving source. In this embodiment, the fourth driving source is a set motor. The transposition component is mainly set to enable the core tube 12 to take out the cut drip bucket and transfer it to the aggregate position by driving the transmission box 13 to rotate after the cutting is completed. After the motor is started, the worm 22 and the worm wheel 21 are driven to rotate so that the core tube 12 and the transmission box 13 are rotated 180° to complete the transposition.

[0054] like Figure 1As shown, as a preferred embodiment of the above embodiment, a collecting assembly 24 is further provided below the cutting assembly 10, and the collecting assembly 24 includes a conveyor belt 241, and a collecting trough 243 for collecting the drip bucket after cutting is provided on the conveyor belt 241, which is located below the core tube 12;

[0055] A plurality of fans 242 are provided on the top of the conveyor belt 241 to blow air to cool down the drip buckets.

[0056] The specific working principle of the present invention is as follows: first, the blow-molded dripping funnel is fed into the feeding assembly 11 after bypassing the turntable, and then introduced into the cutting assembly 10 through the feeding assembly 11;

[0057] The drip bucket introduced into the cutting assembly 10 is accommodated in the space between the first clamping member 1001 and the second clamping member 1002 and is located at the cutting position; after the position is confirmed, the cylinder connected to the first tool holder 1006 is started to move downward, firstly, the first clamping member 1001 is moved downward and contacts the second clamping member 1002 to clamp the drip bucket; and the motor connected to the third gear 18 is started synchronously, and the cylinder connected to the movable seat 19 drives the movable seat 19 and the head 191 to press the driving wheel 15 downward, so that the driving wheel 15 and the core tube 12 are in contact, and under the rotation drive of the driving wheel 15, the core tube 12 can be inserted into the inner cavity of the drip bucket. When the core tube 12 is completely inserted into the drip bucket, the air hole 121 is connected to the transmission box 13, and the gas introduced into the core tube 12 is sprayed into the drip bucket for cooling;

[0058] When the first knife holder 1006 continues to move downward, the first cutter 1003 and the second cutter 1004 are driven to move toward the middle to cut off the dripping funnel. During cutting, cold air is blown to the cutting position through the second cutter 1004 and the air duct 1005 for cooling to ensure a smooth cut.

[0059] After the cutting is completed, the cylinder connected to the first tool holder 1006 drives the first clamping member 1001 and the first tool holder 1006 to move upward to expose the cut drip bucket. At this time, by starting the motor connected to the worm 22, the motor will drive the worm gear 21, the transmission box 13, and the core tube 12 to swing outward, thereby sending the cut drip bucket outward. At the same time, when sending it outward, the feeding assembly 11 synchronously drives the drip bucket to be cut to be sent to the second clamping member 1002 to prepare for the next cutting. At this time, the core tube 12 and the transmission box 13 rotate 180 degrees, and then under the drive of the motor connected to the third gear 18, the core tube 12 is again extended into the drip bucket. In the process of the core tube 12 moving, the drip buckets on the core tube 12 all fall onto the collecting trough 243 under the obstruction of the core tube 12, and then are drawn onto the conveyor belt 241 for collection. The cutting assembly 10 then cycles again to perform the next drip bucket cutting.
