Description

Technical Field

[0001] The utility model relates to the technical field of medicine packaging, in particular to a tube body cutting device for an aluminum-plastic medicine hose. Background Art

[0002] In the aluminum-plastic medical hose industry, adding a layer of plastic liner inside the aluminum hose is becoming more and more popular. On the one hand, it ensures the extrusion feel of the plastic, and on the other hand, the pure aluminum tube outside protects it and has a good insulation and moisture-proof function. Due to the increase in demand and the increasing requirements of customers for precision, the aluminum-plastic medical hose is thin and very soft, so manual cutting is not efficient, and the precision deviation is relatively large, requiring a lot of labor.

[0003] The patent document with application number CN201721202979.6 discloses a secondary composite medicinal aluminum-plastic hose pipe making machine. When working, the automatic control device is programmed, and the data acquisition end and the data output end are electrically connected to the hydraulic column, the cutting motor, and the infrared detection recorder respectively. The power is started, and the raw material is pulled out of the material drum by the traction roller and enters the oven. The raw material softens and enters the mandrel mechanism. The mandrel is squeezed and wrapped by the forming vertical roller, and then enters the forming transverse roller for reinforcement and forming. Then, through the transmission belt, the hose enters the welding box device, and the high-frequency welding head melts and welds the gap at the top of the hose to form a weld. After the hose comes out of the welding device through the conveyor belt, it enters the secondary composite device. The polyethylene layer of the outer wall of the hose after the secondary composite becomes uniform, and it is cooled and solidified by the cooling fan. The secondary composite aluminum-plastic hose is completed, and then the secondary composite aluminum-plastic hose enters the cutting device. The hose cutting length detected by the infrared detection recorder is set by the automatic control device. The automatic control device will control the descent of the hydraulic column and the hydraulic plate on the support column, and the tool will cut the hose. Since the hose is thin and has low hardness, the hose is easily deformed during the process of cutting the hose, so the cut of the hose is uneven and the accuracy of the cutting length is low.

[0004] The patent document with application number CN201910017082.3 discloses an automatic slitting device for plastic bushings in aluminum hoses. When the device is slitting the plastic bushing, the mold knife is controlled by the second cylinder to slitting the bushing head and tail downward. At the slitting station, the rubber wheel is driven by the rubber wheel control motor, and the rubber wheel contacts the bottom of the mandrel, driving the mandrel to rotate at high speed. The bushing head is fixed by another rubber wheel to prevent the bushing from flying out or offset due to high-speed rotation. Due to the high-speed rotation of the mandrel, the cut head will reach the head waste recovery chamber through the head waste recovery groove, completing the slitting process, and the mold knife returns to its original position. By cutting the plastic bushing by putting the plastic bushing on the mandrel, the cutting accuracy of the plastic bushing can be guaranteed, and the incision is not easy to deform. Therefore, when slitting the hose, the hose can be put on the mandrel to achieve the purpose of ensuring cutting accuracy and preventing deformation at the incision. Utility Model Content

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Example 1: Reference Figure 1-Figure 6 As shown, the tube cutting device for the aluminum-plastic medical hose comprises a mounting seat 1, and a mounting hole is provided at the lower end of the support plate 6. A first cylinder 2 is fixed on the mounting seat 1, and a support plate 6 is fixed on the telescopic end of the first cylinder 2. A long hole 7 is provided on the support plate 6, and the length direction of the long hole 7 is parallel to the axial direction of the first cylinder 2. When the first cylinder 2 is started, the first cylinder 2 can drive the support plate 6 to reciprocate in the axial direction of the first cylinder 2.

[0027] A circular cutter 12 is rotatably provided on one side of the support plate 6. Specifically, a rotating ring 11 is coaxially fixed on the circular cutter 12, and the rotating ring 11 is rotatably connected in the fixed ring 10, and the fixed ring 10 is fixed on the support plate 6. A blade is processed on the inner edge of the circular cutter 12. The axis of the circular cutter 12 coincides with the center of the long hole 7. The tube body of the aluminum-plastic medical hose passes through the circular cutter 12. When the circular cutter 12 rotates, the circular cutter 12 is driven to reciprocate in the axial direction of the first cylinder 2, and the blade on the inner edge of the circular cutter 12 can perform circular cutting on the tube body of the aluminum-plastic medical hose.

[0028] The support plate 6 is provided with a driving assembly for driving the ring cutter 12 to rotate. The driving assembly includes a motor 8 fixed on the support plate 6, and a guide wheel 9 is coaxially fixed on the output shaft of the motor 8, and the outer edge of the guide wheel 9 is in rolling contact with the outer edge of the ring cutter 12. The guide wheel 9 is a rubber wheel. When the motor 8 is started, the motor 8 drives the guide wheel 9 to rotate, and the ring cutter 12 is driven to rotate during the rotation of the guide wheel.

[0029] A baffle plate 4 is provided on one side of the mounting base 1, and the baffle plate 4 is connected to the mounting base 1 through the second cylinder 3. Specifically, the telescopic end of the second cylinder 3 is fixed on the mounting base 1, and the baffle plate 4 is fixed on the cylinder body of the second cylinder 3. The axis of the second cylinder 3 is perpendicular to the axis of the first cylinder 2. A mandrel 5 is fixed on the baffle plate 4, and the mandrel 5 passes through the long hole 7 and the ring cutter 12. The mandrel 5 is concentric with the ring cutter 12, and a ring groove 13 corresponding to the ring cutter 12 is opened on the mandrel 5.

[0030] During cutting, the tube body of the aluminum-plastic medical hose is sleeved on the core shaft 5 and one end of the tube body of the aluminum-plastic medical hose is in contact with the baffle 4. Then the motor 8 is started, and the motor 8 drives the ring cutter 12 to rotate through the induction. Figure 5 As shown, the first cylinder 2 is started, and the first cylinder 2 drives the rotating ring knife 12 away from the mounting seat 1 through the support plate 6, and the rotating ring knife 12 can cut the part of the aluminum-plastic medical hose body close to the mounting seat 1. By providing the annular groove 13, it is possible to prevent the ring knife 12 from contacting the core shaft 5 when cutting the body of the aluminum-plastic medical hose.

[0031] Reference Figure 6 As shown, when the first cylinder 2 drives the rotating ring knife 12 to approach the mounting seat 1 through the support plate 6, the rotating ring knife 12 can cut the part of the aluminum-plastic medicinal hose body away from the mounting seat 1.

[0032] After the circular cutter 12 driven by the first cylinder 2 reciprocates in the axial direction of the first cylinder 2 , the tube body of the aluminum-plastic medicinal hose is circularly cut by the circular cutter 12 .

[0033] The circular knife 12 is used to cut the tube body of the aluminum-plastic medicinal hose, and the core shaft 5 is located inside the tube body of the aluminum-plastic medicinal hose when cutting the tube body of the aluminum-plastic medicinal hose. The core shaft 5 can support the tube body of the aluminum-plastic medicinal hose and prevent the incision of the tube body of the aluminum-plastic medicinal hose from being deformed.

[0034] Before cutting the tube body of the aluminum-plastic medical hose, after the tube body of the aluminum-plastic medical hose is sleeved on the core shaft 5, the baffle 4 can block and limit the tube body of the aluminum-plastic medical hose, and the tube body of the aluminum-plastic medical hose can be cut to a fixed length, which can improve the cutting efficiency and ensure the cutting accuracy of the tube body of the aluminum-plastic medical hose.

[0035] After the tube body of the aluminum-plastic medical hose is circumcised, the first cylinder 2 is restored. After the first cylinder 2 is restored, the center of the long hole 7 coincides with the axis of the mandrel 5 again. The second cylinder 3 is started to move the baffle 4 away from the mounting plate. During the process of the baffle 4 moving away from the mounting plate, the mandrel 5 withdraws from the long hole 7 and the circular cutter 12. After the mandrel 5 withdraws from the long hole 7, the tube body of the aluminum-plastic medical hose on the mandrel 5 can be taken out.

[0036] Embodiment 2: Based on Embodiment 1, refer to Figure 7 As shown, a blind hole 14 is provided in the core shaft 5, and a plurality of through holes 15 are evenly distributed on the circumference of the core shaft 5 outside the blind hole 14, the through holes 15 are connected to the blind hole 14, and the blind hole 14 is connected to the negative pressure device.

[0037] After the tube body of the aluminum-plastic medicinal hose is sleeved on the core shaft 5, the negative pressure device is started, which generates negative pressure in both the blind hole 14 and the through hole 15. Under the action of the negative pressure in the through hole 15, the tube body of the aluminum-plastic medicinal hose is stabilized on the core shaft 5, and its stability can be guaranteed when the tube body of the aluminum-plastic medicinal hose is cut, further ensuring the flatness of the incision of the aluminum-plastic medicinal hose and the cutting accuracy.

[0038] When the aluminum-plastic medical hose body on the core shaft 5 is taken out, the aluminum-plastic medical hose body on the core shaft 5 can be taken off after the negative pressure device is turned off.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
