Description

Technical Field

[0001] This invention relates to the field of automatic gate shearing devices, and particularly to an automatic gate shearing device and method for medical curved tubes. Background Technology

[0002] As attached Figure 1 The medical bend shown consists of a bend section and an mounting section connected to the bend section. The overall structure of the medical bend is integrally formed by injection molding. During the injection molding process, in order to ensure that the molten material can be smoothly filled into the cavity of the bend and the mounting section in the mold, a gate is usually set at the outer bend of the bend to reduce the flow resistance of the molten material in the molding cavity and ensure the structural integrity of the molded part. After the medical bend is injection molded, the gate needs to be cut to remove excess waste material and ensure the aesthetics of the medical bend. Currently, existing technologies typically use pneumatic shears to cut the gate. However, since the gate is located at the outer bend of the tube, existing shearing equipment cannot completely conform to the arc contour of the outer bend surface. This results in the gate root not being completely cut off during the shearing process, easily leaving protruding residual glue at the bend. This not only damages the smoothness and aesthetics of the medical tube but also affects the subsequent assembly accuracy and adsorption sealing. Therefore, the industry mainly removes residual glue manually by trimming, which increases labor intensity and labor costs. In addition, the poor trimming consistency leads to poor product quality stability. Therefore, it is necessary to improve the existing gate shearing equipment to meet the gate shearing requirements of medical tubes. Summary of the Invention

[0014] The above-mentioned technical objective of the present invention is achieved through the following technical solution: an automatic gate cutting method for medical bends, employing an automatic gate cutting device for medical bends as described in any of the above technical solutions; comprising: Step 1: First, the clamping and conveying assembly clamps and conveys at least one medical bend from the injection molding station to the gate cutting assembly located at the gate cutting station. The gate cutting assembly first cuts off the entire gate, leaving the root of the gate at the outer bend of the bend. Step 2: The clamping and conveying assembly transports the pre-cut medical bend to the gate trimming assembly. The gate trimming assembly grinds and trims the root of the gate to remove the root of the gate, without damaging the body of the bend during the trimming process. Step 3: The clamping and conveying assembly transports the trimmed medical tubing to the discharge conveyor line to complete the automatic discharge.

[0015] In summary, the present invention has the following beneficial effects: 1. By setting a gate shearing component and a gate trimming component on the base respectively, and setting a clamping and conveying component for conveying medical bends, during the trimming process, at least one medical bend is first clamped and conveyed from the injection molding station to the gate shearing component located at the gate shearing station by the clamping and conveying component. The gate shearing component cuts off the entire gate, leaving the root of the gate at the outer bend of the bend. Then, the clamping and conveying component conveys the pre-cut medical bend to the gate trimming component. The gate trimming component grinds and trims the root of the gate to remove the root of the gate. Finally, the clamping and conveying component clamps the trimmed medical bend onto the discharge conveyor line to achieve automatic discharge. This achieves automatic gate shearing, ensuring the efficiency of gate shearing while ensuring the quality of gate shearing and reducing the cost of manual shearing. 2. The clamping and conveying assembly uses an X-axis horizontal conveying screw slide, a Y-axis horizontal conveying screw slide, and a vertical lifting cylinder to drive the medical bend to achieve horizontal conveying and vertical lifting. A flipping cylinder is fixedly installed at the telescopic end of the vertical lifting cylinder. The flipping cylinder drives the flipping plate to rotate, thereby removing the medical bend from the injection mold. A bend clamping assembly and a bend support fixing assembly are fixedly installed on the flipping plate. The bend clamping assembly uses a synchronous clamping cylinder to drive the clamping plate to move, thereby initially clamping and positioning the bend of the medical bend in the clamping frame. The bend support fixing assembly uses a first positioning tube and a second positioning tube to be inserted from both ends of the bend and the mounting part, respectively. With the end face limit of the first abutment plate and the second abutment plate, the medical bend is positioned and fixed. A support air inflatable ball is set at the end of the second positioning tube. By inflating the support air inflatable ball, it abuts against the inner wall of the bend, preventing the bend from deforming due to force during the shearing process and affecting the shearing effect. 3. The gate shearing assembly uses a vertical abutment plate tangent to the outer bend surface of the bend and perpendicular to the gate. A positioning groove quickly positions the gate, allowing the pneumatic shears to perform initial cutting along the gate root direction, efficiently removing most of the gate waste. The gate trimming assembly uses a sliding lifting assembly to move the arc-shaped abutment plate to conform to the contour of the outer bend surface of the bend, and precisely positions the remaining gate through positioning holes. Simultaneously, a grinding assembly is movably mounted on an arc-shaped contouring seat based on an arc-shaped adjustment assembly. The arc-shaped adjustment assembly uses a first drive motor to drive a horizontal drive gear to rotate, which in turn drives a horizontal rack drive unit and a horizontal arc-shaped adjustment seat to slide horizontally, thus adjusting the horizontal position of the grinding assembly. A second drive motor then drives the vertical... The rotation of the drive gear, in turn, causes the vertical rack drive unit and the vertical arc-shaped adjustment seat to slide along the vertical direction, thereby realizing the vertical position adjustment of the grinding assembly. The structure of the two enables the grinding assembly to flexibly adjust the grinding angle and position along the arc contour of the curved tube, ensuring that the grinding rod can accurately act on the root of the gate. At the same time, the grinding assembly is set by setting a grinding mounting seat on the vertical arc-shaped adjustment seat, and a retaining spring is set between the grinding mounting seat and the vertical arc-shaped adjustment seat. The retaining spring drives the grinding rod to abut against the root of the gate, thereby achieving thorough removal of residual glue, ensuring the flatness and aesthetics of the product surface. An arc-shaped limiting plate is set on the grinding mounting seat to abut against the arc-shaped retaining plate, thereby effectively preventing the grinding rod from damaging the curved tube body during the grinding process.

A discharge conveyor line 5 for discharging the medical curved tube 6 is also fixedly connected to the base 1. During the trimming process, at least one medical curved tube 6 is first clamped and conveyed from the injection molding station by the clamping and conveying assembly 2. The tube is sent to the gate shearing assembly 3 located at the gate shearing station. The gate shearing assembly 3 cuts off the entire gate, leaving the root of the gate at the outer bend of the bend section 61. Then, the clamping and conveying assembly 2 conveys the initially cut medical bend 6 to the gate trimming assembly 4. The gate trimming assembly 4 grinds and trims the root of the gate to remove it. Finally, the clamping and conveying assembly 2 clamps the trimmed medical bend 6 onto the discharge conveyor line 5 to achieve automatic discharge. This achieves automatic gate shearing, ensuring both efficiency and quality of gate shearing.

A Y-direction horizontal conveying screw slide 23 is fixedly connected to the sliding end of the X-direction horizontal conveying screw slide 22 in the Y-direction horizontal direction. The X-direction horizontal conveying screw slide 22, the Y-direction horizontal conveying screw slide 23, and the vertical lifting cylinder 433 drive the medical curved tube 6 to achieve horizontal conveying and vertical lifting. A vertical lifting electric cylinder 24 is fixedly connected to the sliding end of the Y-direction horizontal conveying screw slide 23 in the vertical direction. A vertically aligned tilting cylinder 25 is fixedly connected to the constricted end of the tilting cylinder 25. A tilting plate 26 is fixedly connected to the tilting end of the tilting cylinder 25. The tilting cylinder 25 drives the tilting plate 26 to rotate, thereby removing the medical bent tube 6 from the injection mold. After removal, the tilting cylinder 25 drives the tilting plate 26 to reset. At least one set of bent tube clamping components 27 for clamping the medical bent tube 6 and a bent tube support and fixing component 28 for fixing the bent tube and supporting the inner wall of the bent tube are fixedly connected to the tilting plate 26. In this embodiment, two sets of bent tube clamping components 27 and bent tube support components are provided on the tilting plate 26. The distance between the two sets of bent tube clamping components 27 is equal to the distance between the gate shearing component 3 and the gate trimming component 4, thereby achieving simultaneous gate trimming during the gate shearing process and ensuring the efficiency of gate shearing.

A clamping plate 272 for clamping the bending tube is fixedly connected to the clamping end of the synchronous clamping cylinder 271. A clamping frame 273 for positioning the bending tube is fixedly connected to the clamping plate 272. When clamping the medical bending tube 6, the synchronous clamping cylinders 271 drive the clamping plate 272 to move, thereby initially clamping and positioning the bending tube 61 of the medical bending tube 6 within the clamping frame 273.

A first telescopic cylinder 285 and a second telescopic cylinder 286 for sliding the first positioning tube 281 and the second positioning tube 282 are respectively fixedly connected to the flip plate 26. After the medical curved tube 6 is initially clamped and positioned by the curved tube clamping assembly 27, the first telescopic cylinder 285 drives the first positioning tube 281 to slide from the curved tube... One end of section 61 is inserted into the medical bend 6 until the first abutting plate 283 abuts against and adheres to the end face of the bend section 61. At the same time, the second telescopic cylinder 286 drives the second positioning tube 282 to be inserted into the medical bend 6 from one end of the mounting section 62 until the second abutting plate 284 abuts against and adheres to the end face of the mounting section 62, thereby achieving the positioning and fixing of the medical bend 6. A supporting air inflatable ball 287 for abutting against and supporting the inner wall of the bend section 61 is fixedly provided at the end of the second positioning tube 282 away from the second telescopic cylinder 286. An inflation tube 288 for inflating the supporting air inflatable ball 287 is provided on the second positioning tube 282. By inflating the supporting air inflatable ball 287 through the inflation tube 288, the supporting air inflatable ball is inflated and expands to abut against the inner wall of the bend section 61, avoiding deformation of the bend due to force during the shearing process and affecting the shearing effect.

A positioning hole 45 for positioning the residual gate is opened on the arc-shaped abutment plate 44. The gate trimming assembly 4 drives the arc-shaped abutment plate 44 to conform to the contour of the outer turning surface of the bend through the sliding lifting assembly 43, and accurately positions the residual gate through the positioning hole 45.
