Description

Technical Field

[0001] The utility model relates to the technical field of aseptic pipe connection, in particular to an aseptic pipe connection machine. Background Art

[0002] The sterile pipe connection machine is a medical device that can swap and connect two plastic pipes in a non-sterile environment and ensure the sterility of the pipes. It is widely used in blood collection and supply, clinical surgery, and biopharmaceuticals.

[0003] The existing aseptic pipe connection machine, such as a thermoplastic plastic pipe aseptic pipe connection device disclosed in a Chinese patent with publication number CN210880972U, comprises a base, a pair of U-shaped sliding seats are arranged side by side in the groove cavity opened on the upper surface of the base; a first guide shaft is horizontally arranged between the two longitudinal plates of the sliding seat, a moving clamping part driven by a first motor to move horizontally is slidably arranged on the first guide shaft, and a fixed clamping part adapted to correspond to the moving clamping part is arranged on one longitudinal plate of the sliding seat; a fixing clamping part located between the moving clamping part and the fixed clamping part is provided. A slider is arranged on the first guide shaft between the two sliding seats, a thermoplastic tube holder is movably mounted on the slider, and thermoplastic tube holder slots are horizontally provided on the left and right sides of the thermoplastic tube holder; a left semicircular clamping block and a right semicircular clamping block are respectively arranged on the inner side walls opposite to the moving clamping part and the fixed clamping part of one of the sliding seats, and the left and right semicircular clamping blocks are driven by the second motor arranged on the sliding seat to drive the thermoplastic tube holder to flip; a cutter mounting seat is longitudinally arranged on the side of the base close to the fixed clamping part, and an electric heating cutter driven by a third motor is arranged on the upper end of the cutter mounting seat.

[0004] The electric heating cutter of the sterile pipe connection device disclosed in the above patent is fixed on the cutter mounting seat. When in use, the third motor drives the electric heating cutter to rotate to cut the pipe. After the cutting is completed, the third motor drives the electric heating cutter to reset. Under this structure, the blade of the electric heating cutter is more likely to tilt during multiple rotation movements, thereby affecting the welding effect. Secondly, the third motor will always be damaged during use, but the cost and control difficulty of the third motor as a rotating motor are relatively large, and the replacement cost after damage is high. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the utility model discloses an aseptic pipe connection machine.

[0006] A sterile pipe connection machine, comprising a clamping mechanism and a cutting mechanism, wherein the clamping mechanism and the cutting mechanism are both arranged on a bottom plate, and the clamping mechanism and the cutting mechanism are arranged at two opposite ends of the bottom plate, and a guide rail is arranged between the clamping mechanism and the bottom plate, and the distance between the clamping mechanism and the cutting mechanism is adjusted by driving the clamping mechanism to move on the guide rail;

[0007] The clamping mechanism comprises a pipe support for clamping the pipe, at least two of the pipe supports are provided, at least one of the pipe supports is provided with a rotating motor for driving itself to rotate, and gaps for the cutting mechanism to pass through are provided between adjacent pipe supports.

[0008] During specific use, when two pipe supports are provided, the two pipes are first clamped by the pipe supports, and then the clamping mechanism is driven to move in the direction close to the cutting mechanism. Since there is a gap between adjacent pipe supports for the cutting mechanism to pass through, the clamping mechanism is driven to move until each mechanism passes through the gap to cut the pipe and then the clamping mechanism is driven to move in the direction away from the cutting mechanism to complete the cutting. Subsequently, a rotary motor is used to drive one of the pipe supports to rotate 180° and then the pipes can be connected (after the cutting is completed, the cut end of the pipe is in a molten state, the two molten ports are connected, and the pipe connection is completed after it cools down).

[0009] Preferably, the clamping mechanism is movably connected to the bottom plate via a chassis, the chassis is disposed on a guide rail, and further comprises a second drive motor, wherein the second drive motor is used to drive the chassis to slide on the guide rail.

[0010] Specifically, the clamping mechanism includes several tube supports, each of which is an independent component with gaps between them. However, in the process of moving along the guide rail, the consistency of the movement of each tube support must be ensured. Therefore, it is necessary to set up a chassis structure to ensure that the entire clamping mechanism moves synchronously along the guide rail.

[0011] Preferably, each of the pipe supports includes a clamping portion and a fixing portion, the fixing portion is movably connected to the chassis, the clamping portion includes a first clamp, a slot, and a second clamp which are sequentially arranged in a direction away from the cutting mechanism, the slot and the first clamp and / or the second clamp cooperate to clamp or loosen the pipe, and the clamping mechanism also includes a first driving motor for driving the slot, the first clamp, and the second clamp to clamp or loosen.

[0012] Specifically, the pipe support is configured as a structure of a fixing portion and a clamping portion. The fixing portion is used to maintain a relatively stable position of the pipe support, and the clamping portion is used to clamp the pipeline, so that the entire pipe support has good practicality.

[0013] Preferably, the tube support further comprises a sliding rod, any one of the first clamp and the second clamp and the slot are sleeved with the sliding rod, and the first drive motor drives the first clamp or the second clamp sleeved with the sliding rod to slide along the sliding rod.

[0014] The first driving motor drives the first clamp or the second clamp to slide along the sliding rod. When the first clamp or the second clamp contacts the clamping slot, the pipeline is clamped and then the clamping slot is pushed to slide along the sliding rod.

[0015] Specifically, during the use of the pipe connection machine, it is necessary to frequently clamp and loosen the pipe. A sliding rod structure is provided for sliding between the first clamp and the second clamp and the card slot, so that the clamping part can clamp and loosen the pipe very conveniently, quickly and reliably.

[0016] Preferably, a connecting rod is further provided on the chassis, the fixing portion is movably sleeved on the connecting rod, and the axial direction of the connecting rod is perpendicular to the direction of the guide rail.

[0017] Specifically, since there is a gap between adjacent pipe supports, the structure of the connecting rod is provided so that the gap between adjacent pipe supports is adjustable.

[0018] Preferably, it further comprises a pipe clamping mechanism, wherein the pipe clamping mechanism is used to apply a thrust to the pipe support to reduce the gap between adjacent pipe supports.

[0019] Specifically, when the pipe needs to be connected after the cutting mechanism completes pipe cutting and the rotating motor rotates one of the pipe supports, it is necessary to reduce the distance between adjacent pipe supports so that the two molten ports of the pipe can be in close contact to ensure the reliability of the connection. The structure of the pipe clamping mechanism can reduce the distance between adjacent pipe supports and apply thrust so that the two molten ports of the pipe can be in close contact.

[0020] Preferably, the tube clamping mechanism comprises a swing rod provided on the bottom plate and an arc-shaped protrusion provided on the fixing portion of the tube holder, wherein the arc-shaped protrusion is provided on a side surface of the fixing portion parallel to the direction of the guide rail;

[0021] The swing arm includes a support seat and a movable rod disposed on the top of the support seat and movably connected to the support seat, the height of the movable rod is adapted to the arc-shaped protrusion, the movable rod includes a contact end in contact with the arc-shaped protrusion, and the contact end is inclined toward the direction of the cutting mechanism;

[0022] The swing rod also includes a stopper, which is arranged on the top of the support seat and is used to prevent the movable rod from rotating in a direction close to the clamping mechanism.

[0023] Specifically, under this structure, two pipe clamping mechanisms are usually provided, which are arranged on opposite sides of the clamping mechanism. When the clamping mechanism moves in a direction close to the cutting mechanism and the contact end of the movable rod contacts the arc-shaped protrusion, the arc-shaped protrusion gives a thrust to the movable rod, and the movable rod rotates in a direction away from the clamping mechanism, and the clamping mechanism moves smoothly; when the clamping mechanism moves in a direction away from the cutting mechanism and the contact end of the movable rod contacts the arc-shaped protrusion, the arc-shaped protrusion gives a thrust to the movable rod, but due to the presence of a stopper, the movable rod cannot rotate, so the movable rod will give a reverse thrust to the arc-shaped protrusion. Under the action of this reverse thrust, adjacent pipe supports will approach each other, that is, the distance between adjacent pipe supports can be shortened without the need to additionally set up a pipe clamping motor, so that the melting ports of the pipes are in close contact.

[0024] Preferably, the second drive motor is a lead screw motor, and the chassis is sleeved with the lead screw of the lead screw motor.

[0025] Specifically, under this structure, the movement direction of the clamping mechanism can be controlled by controlling the rotation direction of the screw rod.

[0026] Preferably, the cutting mechanism comprises a fixing mechanism and a cutting blade, the cutting blade is detachably fixed to the fixing mechanism, and the temperature of the cutting blade is adjustable.

[0027] Specifically, when the cutting blade is cutting the pipe, it actually melts the pipe at high temperature and then cuts it off. The materials of the pipes are different, and the melting temperatures are also different. Therefore, it is appropriate to set the temperature of the cutting blade to be adjustable.

[0028] Compared with the prior art, the utility model is beneficial in that:

[0029] (1) The clamping mechanism and the cutting mechanism are arranged at both ends of the bottom plate, and the movement of the clamping mechanism is driven to achieve the pipe cutting structure. On the one hand, the stability of the cutting mechanism during the cutting process is ensured (no failure such as tilting will occur), thereby ensuring the quality of cutting. On the other hand, there is no need to set a rotating drive part for the cutting mechanism, which simplifies the structure of the pipe cutting machine and saves costs.

[0030] (2) The pipe clamping mechanism is used to achieve the purpose of bringing the two pipes close to each other and the melting ports in close contact when connecting the pipes, without the need to set up an additional pipe clamping motor structure, which further simplifies the structure of the connecting machine and makes the connecting machine more convenient to use.

[0032] Figure 2The utility model is a three-dimensional schematic diagram of the arc-shaped protrusion of the aseptic pipe connection machine provided by the utility model in contact with the movable rod. DETAILED DESCRIPTION

[0033] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0034] like Figure 1 , 2 As shown, a sterile tube receiving machine includes a clamping mechanism and a cutting mechanism 20, both of which are arranged on a bottom plate 30, and the clamping mechanism and the cutting mechanism 20 are arranged at two opposite ends of the bottom plate 30, and a guide rail 31 is arranged between the clamping mechanism and the bottom plate 30, and the distance between the clamping mechanism and the cutting mechanism 20 is adjusted by driving the clamping mechanism to move on the guide rail 31;

[0035] The clamping mechanism includes a pipe support for clamping the pipe. There are at least two pipe supports, at least one of which is provided with a rotating motor 11 for driving its own rotation. A gap is provided between adjacent pipe supports for the cutting mechanism 20 to pass through.

[0036] The clamping mechanism is movably connected to the bottom plate 30 via a chassis 12 . The chassis 12 is disposed on the guide rail 31 and further includes a second drive motor 13 . The second drive motor 13 is used to drive the chassis 12 to slide on the guide rail 31 .

[0037] The clamping mechanism includes a plurality of tube supports, each of which is an independent component with gaps between them. However, the consistency of movement of each tube support must be ensured during movement along the guide rail 31. Therefore, it is necessary to set up a structure of the chassis 12 to ensure synchronization of the entire clamping mechanism when moving along the guide rail 31.

[0038] Each pipe support includes a clamping portion and a fixing portion 41, the fixing portion 41 is movably connected to the chassis 12, the clamping portion includes a first clamp 43, a slot 44, and a second clamp 45 which are arranged in sequence in the direction away from the cutting mechanism 20, the slot 44 and the first clamp 43 and / or the second clamp 45 cooperate to clamp or loosen the pipe, and the clamping mechanism also includes a first drive motor 46 for driving the slot 44, the first clamp 43, and the second clamp 45 to clamp or loosen.

[0039] The pipe support is configured as a structure of a fixing portion 41 and a clamping portion. The fixing portion 41 is used to keep the position of the pipe support relatively stable, and the clamping portion is used to clamp the pipeline, so that the entire pipe support has good practicality.

[0040] The tube support further comprises a sliding rod 42 , any one of the first clamp 43 and the second clamp 45 and the slot 44 are sleeved with the sliding rod 42 , and the first driving motor 46 drives the first clamp 43 or the second clamp 45 sleeved with the sliding rod 42 to slide along the sliding rod 42 .

[0041] The first driving motor 46 drives the first clamp 43 or the second clamp 45 to slide along the sliding rod 42 . When the first clamp 43 or the second clamp 45 contacts the clamping groove 44 , the pipe is clamped and then the clamping groove 44 is pushed to slide along the sliding rod 42 .

[0042] During the use of the pipe connection machine, it is necessary to frequently clamp and release the pipe. The structure of the sliding rod 42 is provided for any one of the first clamp 43 and the second clamp 45 and the card slot 44 to slide, so that the clamping part can clamp and release the pipe very conveniently, quickly and reliably.

[0043] A connecting rod 14 is further provided on the chassis 12 , and the fixing portion 41 is movably sleeved on the connecting rod 14 , and the axial direction of the connecting rod 14 is perpendicular to the direction of the guide rail 31 .

[0044] Since there is a gap between adjacent tube supports, the structure of the connecting rod 14 makes the gap between adjacent tube supports adjustable.

[0045] The invention also comprises a pipe clamping mechanism, which is used for applying a thrust to the pipe bracket to reduce the gap between adjacent pipe brackets.

[0046] When the cutting mechanism 20 completes pipe cutting and the rotating motor 11 rotates one of the pipe supports and the pipe needs to be connected, the distance between adjacent pipe supports needs to be reduced so that the two molten ports of the pipe can be in close contact to ensure the reliability of the connection. The structure of the pipe clamping mechanism can effectively reduce the distance between adjacent pipe supports and apply thrust so that the two molten ports of the pipe can be in close contact.

[0047] The pipe clamping mechanism includes a swing rod disposed on the bottom plate 30 and an arc-shaped protrusion 51 disposed on the fixing portion 41 of the pipe holder. The arc-shaped protrusion 51 is disposed on a side surface of the fixing portion 41 parallel to the direction of the guide rail 31.

[0048] The swing arm includes a support seat 52 and a movable rod 53 disposed on the top of the support seat 52 and movably connected to the support seat 52. The height of the movable rod 53 matches the arc-shaped protrusion 51. The movable rod 53 includes a contact end in contact with the arc-shaped protrusion 51, and the contact end is tilted toward the direction of the cutting mechanism 20.

[0049] The swing arm further includes a stopper, which is disposed on the top of the support seat 52 and is used to prevent the movable rod 53 from rotating in a direction close to the clamping mechanism.

[0050] Under this structure, two pipe clamping mechanisms are usually provided, which are arranged on opposite sides of the clamping mechanism. When the clamping mechanism moves toward the direction close to the cutting mechanism 20 and the contact end of the movable rod 53 contacts the arc-shaped protrusion 51, the arc-shaped protrusion 51 gives a thrust to the movable rod 53, and the movable rod 53 rotates in the direction away from the clamping mechanism, and the clamping mechanism moves smoothly; when the clamping mechanism moves in the direction away from the cutting mechanism 20 and the contact end of the movable rod 53 contacts the arc-shaped protrusion 51, the arc-shaped protrusion 51 gives a thrust to the movable rod 53, but due to the presence of a stopper, the movable rod 53 cannot rotate, so the movable rod 53 will give a reverse thrust to the arc-shaped protrusion 51. Under the action of the reverse thrust, adjacent pipe supports will approach each other, that is, the distance between adjacent pipe supports can be reduced without the need to additionally set up a pipe clamping motor, so that the melting ports of the pipelines are in close contact.

[0051] The stopper provided in this embodiment is a limiting groove arranged on the top of the support seat 52, and the contact end of the movable rod 53 protrudes from the limiting groove. There is a gap between the movable rod 53 and the side wall of the limiting groove away from the clamping mechanism, and there is no gap between the movable rod 53 and the side wall of the limiting groove close to the clamping mechanism.

[0052] The second drive motor 13 is a screw motor, and the chassis 12 is sleeved with the screw of the screw motor.

[0053] In this structure, the movement direction of the clamping mechanism can be controlled by controlling the rotation direction of the screw rod.

[0054] The cutting mechanism 20 includes a fixing mechanism 21 and a cutting blade 22. The cutting blade 22 is detachably fixed to the fixing mechanism 21, and the temperature of the cutting blade 22 is adjustable.

[0055] When the cutting blade 22 is cutting the pipe, it actually melts the pipe at high temperature and then cuts it off. The materials of the pipes are different, and the melting temperatures are also different. Therefore, it is appropriate to set the temperature of the cutting blade 22 to be adjustable.

[0056] In specific use, when two pipe supports are provided, the pipe supports are first used to clamp the pipe, and then the clamping mechanism is driven to move in a direction close to the cutting mechanism 20. Since there is a gap between adjacent pipe supports for the cutting mechanism 20 to pass through, the clamping mechanism is driven to move until the cutting mechanism 20 passes through the gap to cut the pipe, and then the clamping mechanism is driven to move in a direction away from the cutting mechanism 20 to complete the cutting. When the clamping mechanism is separated from the cutting mechanism 20, the rotating motor 11 is used to drive one of the slots 44 to rotate 180°, and the clamping mechanism is driven to move in a direction away from the cutting mechanism 20 again. Under the action of the pipe clamping mechanism, the distance between adjacent pipe supports is reduced, and at the same time, the pipe clamping mechanism continues to give thrust so that the molten ports of the pipes are in close contact, and the pipe connection is completed after the molten ports are cooled.
