Description

Technical Field

[0001] This utility model relates to the field of rotary disc technology for drip molding machines, and specifically to an indexing and positioning device for a rotary disc of a drip molding machine. Background Technology

[0002] A drip molding machine is a specialized piece of equipment that precisely drips and solidifies liquid plastic raw materials into molded shapes using a drip molding process. It is primarily used to create three-dimensional drip molded products on various material surfaces, such as trademarks, signs, ornaments, and anti-slip mats. Its working principle is as follows: The plastic raw material (such as PVC or PU) is first heated and melted into a liquid state, which is then conveyed to the drip molding head by a feeding system. Under the instructions of a control system (such as a PLC program or CNC device), the drip molding head drips the liquid raw material onto a mold or substrate according to a preset trajectory and quantity. After dripping, the plastic raw material is solidified through natural cooling or heating, thus forming a drip molded product with a specific shape and function. The significance of a drip molding machine lies in its automation and precision in drip molding production, significantly improving production efficiency. Compared to traditional manual drip molding, it ensures consistency in product size and shape. It also allows for the creation of complex patterns through programming, expanding the application of drip molding technology in clothing, electronics, daily necessities, and many other fields. It provides technical support for enhancing the decorative and functional aspects of products, promoting the standardization and large-scale development of related industries.

[0003] A search of the public announcement (CN216230381U) reveals "a drip molding machine," which discloses that "it includes a body, the body comprising a platform and a positioning device; the positioning device includes a transverse positioning mechanism, a longitudinal positioning component, a clamping component, and a positioning plate; the transverse positioning mechanism includes a guide rail and a transverse positioning strip; the longitudinal positioning component includes a longitudinal positioning strip; the guide rail is slidably connected to the positioning plate, and the longitudinal positioning strip is bolted to the positioning plate; the transverse positioning mechanism, the longitudinal positioning mechanism, and the clamping component can all move and position quickly, achieving the effect of quickly positioning the template."

[0004] Although the above technical solution can quickly position the template through the positioning device, the template needs to be fixed again every time it is dripped, which makes the position of the template unable to be changed, thus slowing down the processing efficiency.

[0005] To address the aforementioned issues, this application proposes a rotary indexing and positioning device for a drip molding machine. Utility Model Content

[0006] This utility model addresses the technical problems existing in the prior art by providing a rotary indexing and positioning device for a drip molding machine.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A rotary indexing and positioning device for a drip molding machine includes a base and a drip molding machine body. A rotating component is installed on the base. The rotating component includes a rotating column, an indexing plate, a turntable, and a drip molding mold. The lower end of the rotating column is rotatably connected to the base. The side surface of the rotating column is fixedly connected to the indexing plate. The upper end of the rotating column is fixedly connected to the turntable. The upper surface of the turntable is fixedly connected to the drip molding mold.

[0008] The inner wall of the base is provided with a positioning component, which includes a sliding sleeve, a sliding column, a ball bearing, and a spring. One end of the sliding sleeve is fixedly connected to the base, and the end of the sliding sleeve away from the base is slidably connected to the sliding column. The outer surface of the ball bearing is in contact with the sliding column. Both the sliding sleeve and the sliding column pass through the interior of the spring. One end of the spring is fixedly connected to the base, and the end of the spring away from the base is fixedly connected to the sliding column.

[0009] Preferably, the side surface of the turntable is provided with six equidistant circular grooves, which are adapted to the ball bearings. By providing the circular grooves, the ball bearings will enter the circular grooves along the side surface of the turntable as the turntable rotates a certain angle, achieving positioning and preventing the circular grooves from continuing to rotate under inertia and causing misalignment of the dripping material.

[0010] Preferably, a No. 1 motor is fixedly connected to the inner wall of the base, and a sector-shaped disk is fixedly connected to the output end of the No. 1 motor. A cam is fixedly connected to the upper surface of the sector-shaped disk, and a locking pin is fixedly connected to the lower surface of the cam. By setting the No. 1 motor, the No. 1 motor drives the sector-shaped disk to rotate, the sector-shaped disk drives the cam, and the cam drives the locking pin and the indexing plate to rotate.

[0011] Preferably, the indexing plate has a slot inside, which is adapted to the locking post. A second motor is provided on the side surface of the indexing plate, which is adapted to the sector disk. There are six slots and six motors arranged in a circular array. By setting the slots and the second motor, the locking post can engage with the slot once per revolution during rotation. Similarly, the sector disk will also contact the inner wall of the second motor once per revolution. Thus, for every revolution of the sector disk, the indexing plate rotates 60°, and the indexing plate drives the turntable on the rotating post to perform intermittent equal-division rotation.

[0012] Preferably, a second motor is fixedly connected to the inner wall of the base, and a first threaded rod is fixedly connected to the output end of the second motor. A first threaded sleeve is threadedly connected to the side surface of the first threaded rod, and a horizontal longitudinal slide is fixedly connected to the end of the first threaded sleeve away from the first threaded rod. The second motor drives the first threaded rod to rotate, and the first threaded rod pushes and pulls the first threaded sleeve, thereby realizing the horizontal longitudinal sliding of the horizontal longitudinal slide.

[0013] Preferably, the inner wall of the base is fixedly connected to two symmetrically distributed guide rails, and the inner walls of the guide rails are slidably connected to the horizontal longitudinal slide. By setting the guide rails, the horizontal longitudinal slide is easily limited and can slide along the direction of the guide rails.

[0014] Preferably, a No. 3 motor is fixedly connected to the outer surface of the horizontal longitudinal slide, a No. 2 threaded rod is fixedly connected to the output end of the No. 3 motor, a horizontal transverse slide is threadedly connected to the side surface of the No. 2 threaded rod, and a No. 1 guide rod is slidably connected inside the horizontal transverse slide. Both ends of the No. 1 guide rod are fixedly connected to the horizontal longitudinal slide. By setting the No. 3 motor, the No. 2 threaded rod is rotated by the No. 3 motor, allowing the horizontal transverse slide to slide horizontally on the No. 1 guide rod.

[0015] Preferably, a No. 4 motor is fixedly connected to the upper surface of the horizontal slide, the output end of the No. 4 motor is fixedly connected to a No. 3 threaded rod, the side surface of the No. 3 threaded rod is threadedly connected to the body of the dispensing machine, and two No. 2 guide rods are fixedly connected inside the horizontal slide, with the side surfaces of the No. 2 guide rods slidably connected to the body of the dispensing machine. By setting up the No. 4 motor, the vertical height of the dispensing machine body is adjusted as the No. 3 threaded rod rotates within the dispensing machine body, thereby improving the accuracy of the dispensing position.

[0016] The beneficial effects of this utility model are:

[0017] 1. A rotary indexing and positioning device for a drip molding machine, which, by setting a rotating component, enables the drip molding mold to rotate with the rotary table, thereby allowing it to quickly move to the next indexing position after drip molding is completed, and re-enter the drip molding mold below the drip molding machine, realizing intermittent rotary drip molding, and continuously processing a large number of drip molded products to form a production line, thereby greatly improving production efficiency.

[0018] 2. A rotary indexing and positioning device for a drip molding machine, which, by setting a positioning component, enables the rotary table to be quickly positioned after rotating a certain angle, so that the bottom of the drip molding machine can be aligned with the drip molding mold, achieving rapid alignment and completing the drip molding. It can also effectively prevent the rotary table from spinning idly or shaking, which could cause misalignment between the drip molding mold and the drip molding machine, thereby greatly improving the accuracy of the drip molding position and reducing the scrap rate.

[0028] Reference Figure 1-4A rotary indexing and positioning device for a drip molding machine includes a base 1 and a drip molding machine body 2. A rotating assembly is mounted on the base 1, comprising a rotating column 3, an indexing plate 4, a turntable 5, and a drip molding mold 6. The lower end of the rotating column 3 is rotatably connected to the base 1, the side surface of the rotating column 3 is fixedly connected to the indexing plate 4, and the upper end of the rotating column 3 is fixedly connected to the turntable 5. A first motor 12 is fixedly connected to the inner wall of the base 1. A sector-shaped disk 13 is fixedly connected to the output end of the first motor 12. A cam 14 is fixedly connected to the upper surface of the sector-shaped disk 13, and a locking pin 15 is fixedly connected to the lower surface of the cam 14. By setting the first motor 12, the first motor 12 drives the sector-shaped disk 13 to rotate, the sector-shaped disk 13 drives the cam 14, and the cam 14 drives the locking pin 15 and the indexing plate 4 to rotate. The indexing plate 4 has a slot 16 inside, which is adapted to the locking post 15. A second motor 17 is set on the side surface of the indexing plate 4, which is adapted to the sector disk 13. There are six slots 16 and six motors 17 arranged in a circular array. By setting the slots 16 and the motors 17, the locking post 15 can be locked into the slot 16 once per revolution during rotation. Similarly, the sector disk 13 will also be in contact with the inner wall of the motor 17 once per revolution. Thus, for every revolution of the sector disk 13, the indexing plate 4 rotates 60°. The indexing plate 4 drives the turntable 5 on the rotating post 3 to rotate intermittently and equally. The second motor 17 is fixedly connected to the inner wall of the base 1, and the output end of the second motor 17 is fixedly connected to a screw. A threaded rod 18 has a threaded sleeve 19 threaded to its side surface. A horizontal longitudinal slide 20 is fixedly connected to the end of the threaded sleeve 19 furthest from the threaded rod 18. A second motor 17 drives the threaded rod 18 to rotate, pushing and pulling the threaded sleeve 19, thus achieving horizontal longitudinal sliding of the slide 20. Two symmetrically distributed guide rails 21 are fixedly connected to the inner wall of the base 1. The inner walls of the guide rails 21 are slidably connected to the horizontal longitudinal slide 20. The guide rails 21 limit the horizontal longitudinal slide 20, allowing it to slide along the direction of the guide rails 21. A third motor 22 is fixedly connected to the outer surface of the horizontal longitudinal slide 20. The output end of the third motor 22 is fixedly connected to the threaded rod 20. 3. A horizontal transverse slide 24 is threadedly connected to the side surface of the second threaded rod 23. A first guide rod 25 is slidably connected inside the horizontal transverse slide 24. Both ends of the first guide rod 25 are fixedly connected to the horizontal longitudinal slide 20. A third motor 22 is installed to drive the second threaded rod 23 to rotate, allowing the horizontal transverse slide 24 to slide horizontally on the first guide rod 25. A fourth motor 26 is fixedly connected to the upper surface of the horizontal transverse slide 24. The output end of the fourth motor 26 is fixedly connected to the third threaded rod 27. The side surface of the third threaded rod 27 is threadedly connected to the drip molding machine body 2. Two second guide rods 28 are fixedly connected inside the horizontal transverse slide 24. The side surfaces of the second guide rods 28 are slidably connected to the drip molding machine body 2.By setting up motor 26, the vertical height of the drip molding machine body 2 is adjusted as it drives threaded rod 27 to rotate within the machine body 2, thereby improving the accuracy of the drip molding position.

[0029] The inner wall of the base 1 is provided with a positioning component, which includes a sliding sleeve 7, a sliding column 8, a ball bearing 9, and a spring 10. One end of the sliding sleeve 7 is fixedly connected to the base 1, and the end of the sliding sleeve 7 away from the base 1 is slidably connected to the sliding column 8. The outer surface of the ball bearing 9 is in contact with the sliding column 8. Both the sliding sleeve 7 and the sliding column 8 pass through the interior of the spring 10. One end of the spring 10 is fixedly connected to the base 1, and the end of the spring 10 away from the base 1 is fixedly connected to the sliding column 8. The upper surface of the turntable 5 is fixedly connected to the drip molding mold 6. The side surface of the turntable 5 is provided with six equally spaced circular grooves 11. The circular grooves 11 are adapted to the ball bearing 9. By setting the circular grooves 11, when the turntable 5 rotates a certain angle, the ball bearing 9 will be inserted into the circular groove 11 along the side surface of the turntable 5 to achieve positioning and prevent the circular groove 11 from continuing to rotate under inertia, which would cause the drip molding to be misaligned.

[0030] Working principle:

[0031] In operation, motor 12 is started, which drives the sector disk 13 to rotate. The sector disk 13 drives the cam 14, which in turn drives the locking pin 15 to rotate. The locking pin 15 engages with the locking slot 16 once per rotation. Simultaneously, the sector disk 13 engages with motor 17 once per rotation, thus achieving intermittent six-division rotation of the indexing disk 4. The rotation of the indexing disk 4 drives the turntable 5 on the rotating column 3 to rotate intermittently. When the dripping mold 6 on the turntable 5 is located below the dripping machine body 2, the dripping process is started. The plastic injection molding machine body 2 performs drip molding on it. Since the clamping column 15 will not engage with the clamping groove 16 for a period of time after each rotation, it will be in an idle state. This idle time is the interval time during the rotation of the turntable 5. The interval time is used for drip molding of the drip molding mold 6, thereby realizing continuous rotation production. Every time the turntable 5 rotates 60°, the circular groove 11 will engage the ball 9 once, thereby positioning the turntable 5 and preventing the turntable 5 from continuing to rotate due to inertia during the idle process of the fan-shaped disk 13, which would cause the drip molding to be misaligned and reduce the scrap rate.

[0032] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0033] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
