[0006] The main drawbacks of the above technology include: the brush is difficult to enter the wire feeding device smoothly, and it is easy to slip during the conveying process.

[0007] Therefore, providing a wire feeding device that allows brush wires to enter easily and prevents slippage during the conveying process has become a problem that the industry needs to solve. Summary of the Invention

[0008] To address the shortcomings of existing technologies, the main objective of this invention is to provide a wire feeding device for an endoscope cleaning and disinfection machine, which allows the brush wire to easily enter and prevents slippage during the feeding process.

[0009] To achieve the above-mentioned main objectives, this utility model discloses a wire feeding device for an endoscope washing and disinfection machine, comprising:

[0010] The opening and closing mechanism includes a support base and a pressing block; the pressing block presses on the support base; the front end of the pressing block is provided with a pressing shaft, and the rear end of the pressing block is the opening and closing end;

[0011] The lifting mechanism, located below the pressing block, includes a lifting motor, a lead screw driven by the lifting motor, and an internally threaded tube sleeved on the lead screw. The top end of the internally threaded tube is connected to the pressing shaft via a connecting rod. The end of the connecting rod is splinedly engaged with the pressing shaft.

[0012] The wire feeding wheel mechanism includes a wire feeding motor and several wire feeding wheels; each wire feeding wheel includes a support wheel and a pressing wheel; the support wheel is mounted on a support base and includes a front support wheel and a rear support wheel; the pressing wheel is located on a pressing block and includes a front pressing wheel and a rear pressing wheel; the front pressing wheel is located directly above the front support wheel, and the rear pressing wheel is located directly above the rear support wheel; each wire feeding wheel is driven to rotate by its coaxial drive wheel; the drive wheel is driven to rotate directly or indirectly by the wire feeding motor.

[0013] In this invention, a lifting motor drives a lead screw to rotate, which in turn moves the internal threaded tube up and down, thereby driving a connecting rod to rotate the pressing shaft, causing the opening and closing end to open upwards. Once the brush is conveyed to the support base, the opening and closing end of the pressing block presses downwards, thus allowing the brush to enter smoothly.

[0014] In this invention, the brush line is clamped by the front pressing wheel and the front support wheel, and the rear pressing wheel and the rear support wheel during conveying.

[0015] In this invention, a dual-drive wheel system is used, which enables both the upper and lower wire feeding wheels to be driven by the drive wheel, effectively preventing slippage during the conveying process and improving the stability of the conveying.

[0016] In this invention, when the internally threaded tube rises, the opening and closing end rotates upward and moves away from the support seat; at this time, the brush line enters between the support wheel and the pressing wheel; subsequently, the internally threaded tube descends, the opening and closing end rotates downward and moves closer to the support seat, and the brush line is clamped by the support wheel and the pressing wheel, completing the positioning, and can begin to be conveyed forward.

[0017] According to a specific embodiment of the present invention, the connecting rod includes a first connecting rod and a second connecting rod. The two ends of the first connecting rod are respectively connected to an internally threaded pipe and the second connecting rod, and the end of the second connecting rod is splinedly engaged with a pressing shaft.

[0018] According to a specific embodiment of the present invention, the four drive wheels are a lower rear wheel, a lower front wheel, an upper rear wheel, and an upper front wheel; the lower rear wheel, the lower front wheel, and the upper front wheel all include gears and pulleys, and the upper rear wheel includes a pulley.

[0019] In this design, the gear and pulley of the lower rear wheel are coaxial, the gear and pulley of the lower front wheel are coaxial, and the gear and pulley of the upper front wheel are coaxial.

[0020] According to a specific embodiment of this utility model, the wire feeding motor drives the gear of the lower rear wheel through a reduction gear system, and the lower rear wheel drives the pulley of the lower front wheel through a belt; the gear of the lower front wheel meshes with the gear of the upper front wheel, and the upper front wheel drives the pulley of the upper rear wheel through a belt.

[0021] In this design, the pulley of the lower rear wheel is connected to the pulley of the lower front wheel via a belt, and the pulley of the upper front wheel is connected to the pulley of the upper rear wheel via a belt. The power transmission path of the wire feeding motor is as follows: wire feeding motor—reduction gear system—lower rear wheel gear—lower rear wheel pulley—lower front wheel pulley—lower front wheel gear—upper front wheel gear—upper front wheel pulley—upper rear wheel pulley. The four drive wheels rotate synchronously to complete the transmission of the brush thread.

[0022] According to a specific embodiment of the present invention, the wire feeding device further includes a wire output detection mechanism, which includes:

[0023] The mounting base has a partition with a shaft hole; the partition divides the mounting base into a front groove and a back groove; the mounting base is located on the support base, in front of the front support wheel;

[0024] A sliding assembly includes a fixing member and a sliding member. The fixing member is fixedly disposed on one side within a front groove, and the sliding member is slidably disposed within the front groove on the opposite side of the fixing member. Both opposite surfaces of the fixing member and the sliding member protrude outward. A receiving groove is provided on the back of the sliding member.

[0025] The rotating assembly includes an eccentric wheel, a detection pendulum shaft, and a detection pendulum rod; the detection pendulum shaft passes through a shaft hole, one end of which is fixedly connected to the non-axial part of the eccentric wheel surface, and the other end of which is fixedly connected to the detection pendulum rod; the eccentric wheel is located in the front groove and the receiving groove, and the detection pendulum rod is located in the back groove; a signal transmitter is provided at the end of the detection pendulum rod.

[0026] The signal receiver is located on one side of the back slot; when the detection lever moves to its end and faces the signal receiver, the signal receiver receives the signal emitted by the signal transmitter.

[0027] In this design, the front groove is located on the upper side of the partition plate, and the back groove is located on the lower side of the partition plate; the eccentric wheel is located within the space formed by the front groove and the receiving groove, and a fixing seat for fixing the detection pendulum shaft is provided in the shaft hole.

[0028] After the brush thread is fed out by the thread feeding wheel mechanism, it passes through the gap between the fixed part and the sliding part. The sliding part is pushed open by the brush thread and moves away from the fixed part, driving the eccentric wheel to rotate. Since the detection swing shaft is limited by the shaft hole, it can only be driven to rotate by the eccentric wheel, which in turn drives the detection swing arm to swing until the signal transmitter at the end of the detection swing arm is facing the signal receiver. The signal receiver receives the signal emitted by the signal transmitter, indicating that the brush thread has been fed out, thus realizing the thread output detection.

[0029] According to a specific embodiment of the present invention, a guide shaft is provided at the end of the sliding member away from the fixed member, and a guide hole is provided on the edge of the front groove, and the guide shaft is inserted into the guide hole.

[0030] In this design, there are two guide shafts that are parallel to each other; the sliding component is slidably mounted on the guide shafts.

[0032] According to a specific embodiment of the present invention, the wire detection mechanism further includes a reset assembly, which includes a reset spring and a spring support. The spring support is installed in the back groove, and one end of the reset spring is connected to the spring support and the other end is connected to the detection swing rod.

[0033] In this solution, when no brush line passes through the gap between the fixed part and the sliding part, the reset spring drives the detection swing rod to reset, the detection swing rod drives the detection swing shaft to rotate back, the detection swing shaft drives the eccentric wheel to rotate back, and the eccentric wheel pushes the sliding part to move closer to the fixed part until the sliding part is reset.

[0034] According to a specific embodiment of the present invention, the wire feeding device further includes a length measuring component, which includes a rolling wheel, a connecting shaft, a signal wheel, and a length signal receiver. The rolling wheel is disposed on a support base and is located between the front support wheel and the rear support wheel. When feeding the wire, the rolling wheel contacts the brush wire. The two ends of the connecting shaft are respectively connected to the rolling wheel and the signal wheel. A length signal transmitter is provided on the signal wheel. The length signal receiver is installed facing the signal wheel.

[0035] In this scheme, the signal wheel is located between the lower rear wheel pulley and the lower front wheel pulley; when feeding the wire, the brush wire drives the rolling wheel to rotate, and the rolling wheel drives the signal wheel to rotate synchronously through the connecting shaft.

[0036] According to a specific embodiment of this utility model, the length signal transmitter is a magnet, and four magnets are evenly distributed in a ring on the outer surface of the signal wheel; as the signal wheel rotates, each time a magnet passes the length signal receiver, it is counted once, which means that the brush line has been sent out a certain length (1 / 4 of the circumference of the rolling wheel).

[0037] According to a specific embodiment of the present invention, the wire feeding device further includes a swing mechanism and a front housing. The swing mechanism includes a swing motor, a swing plate, and a porous brush feeding guide block.

[0038] The swing motor drives the vertically positioned swing shaft to rotate, and the swing plate is fixedly sleeved on the swing shaft; the support base is fixedly installed on the swing plate.

[0040] The multi-hole brush feeding guide block has three brush outlet holes at the same height; the rear surface of the multi-hole brush feeding guide block is arc-shaped and matches the arc-shaped surface of the front housing.

[0041] In this design, the rotation of the swing shaft drives the swing plate to rotate, and the rotation of the swing plate drives the support base to rotate. The front housing rotates along the rear surface of the multi-hole brush guide block, so that the wire outlet hole corresponds to different brush outlet holes as needed, thereby cleaning the three cavities of the endoscope in sequence. This avoids moving the endoscope when brushing it and effectively improves the cleaning efficiency.

[0042] According to a specific embodiment of this utility model, the swing motor is arranged horizontally, and drives the swing shaft through a horizontal bevel gear and a vertical bevel gear; the vertical bevel gear is fixedly connected to the swing shaft; both the vertical bevel gear and the swing shaft are hollow, forming a cable tray; the lifting motor is located below the vertical bevel gear, and the lead screw passes through the cable tray from below, with the cable tray sleeved outside the internally threaded tube. This arrangement saves space and has a compact structure.

[0043] This utility model has the following beneficial effects:

[0044] 1. After the opening and closing mechanism is opened, the brush thread enters, and then the opening and closing mechanism closes, which ensures that the brush thread can enter smoothly without obstruction;

[0045] 2. The wire feeding wheel mechanism adopts a dual-drive wheel system, which means that both the upper and lower wire feeding wheels are driven by the drive wheels, effectively avoiding slippage during the wire feeding process and improving the stability of wire feeding;

[0046] 3. After the brush thread is fed out by the thread feeding wheel mechanism, the detection swing arm swings, so that the signal transmitter at the end of the detection swing arm faces the signal receiver. Then the signal receiver receives the signal emitted by the signal transmitter, indicating that the brush thread has been fed out, realizing real-time sensing of the thread output; the structure is simple and the operation is convenient.

[0047] 4. The length measuring component can measure the length of the fed brush thread, facilitating precise control of the thread feeding length;

[0048] 5. The swing motor drives the support base to adjust the position of the brush outlet, which can clean the three cavities of the endoscope in sequence without moving the endoscope, effectively improving the cleaning efficiency;

[0049] 6. Both the vertical bevel gear and the swing shaft are hollow, forming a cable tray; the lifting motor is located below the vertical bevel gear, and the lead screw passes through the cable tray from below; this arrangement saves space and has a compact structure.
