Description

Technical Field

[0001] The invention relates to the technical field of plastic product processing equipment, in particular to an automatic rotary cutting and trimming machine for plastic products. Background Art

[0002] Plastic products are a general term for household and industrial products made primarily from plastic. This encompasses products made using all processes, including injection molding and blister molding. Plastic is a type of synthetic polymer material with plasticity. Along with synthetic rubber and synthetic fibers, it forms one of the three most essential synthetic materials in daily life. Specifically, plastic is a material composed primarily of natural or synthetic resins, with various additives added. It can be molded into a specific shape under certain conditions of temperature and pressure, and retains its shape at room temperature.

[0003] After plastic products are molded, they often form overflow or burrs on the edges. This phenomenon is mainly caused by improper adjustment of the injection molding machine, such as too high injection pressure, insufficient clamping force, too much material added, too long holding time, too high material temperature, loose mold fit or too low viscosity of the plastic raw material during molding. Therefore, the surface of the plastic product needs to be trimmed before it is put into use.

[0004] The edge of the barrel of cylindrical plastic products is very prone to burrs during the processing process. Currently, when trimming the burrs of plastic products, most operators do it manually or use simple trimming equipment to grind the burrs of the plastic products. In addition, the outer diameters of cylindrical plastic products vary, and manual repair operations are time-consuming and labor-intensive, making it difficult to adapt to large-scale production of plastic products.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] See also Figure 1 、 8 -10. The present invention provides a technical solution, an automatic peeling and trimming machine for plastic products, comprising a belt conveyor 1 for conveying plastic products, a swing grabbing part 2 comprising a supporting driving member 21 provided on one side of the belt conveyor 1, a connecting disk 22 whose center is fixed on the power output vertical axis of the supporting driving member 21, a plurality of swing arms 23 fixed to the outer edge of the connecting disk 22 along the circumferential direction and extending radially respectively, a C-shaped frame 24 fixed to the outer end of the swing arm 23, and a radial clamping mechanism 25 fixed to both ends and the middle of the C-shaped frame 24, the radial clamping mechanism 25 is provided with a radial clamping mechanism along the C-shaped frame 24. The rotary cutting and trimming part 3 includes a bracket 31 which is arranged on the outside of the supporting driving member 21 and can be raised and lowered, a rotary cutting motor 32 installed on the top of the bracket 31, a turntable 33 whose center is fixed to the bottom end of the power output shaft of the rotary cutting motor 32, three sliding bases 34 that slide radially along the turntable 33, and a top surface cutter head 36, an outer edge cutter head 37 and an inner edge cutter head 38 that are respectively detachably fixed to the bottom of the sliding base 34. The distance between the central axis of the turntable 33 and the central axis of the connecting disk 22 is equal to the distance between the center of the C-shaped frame 24 and the central axis of the connecting disk 22.

[0035] A photoelectric detection module 4 is installed at a position on the frame of the belt conveyor 1 corresponding to the middle of the swing grabbing part 2 .

[0036] In summary, cylindrical plastic products are placed upright at intervals on belt conveyor 1, which conveys them. When photoelectric detection module 4 detects a cylindrical plastic product, the control circuit temporarily stops belt conveyor 1. At this point, support drive 21 rotates C-shaped frame 24 via connecting plate 22 and swing arm 23.

[0037] The C-shaped frame 24 is a ring-shaped plate with a notch. The C-shaped frame 24 rotates to a position corresponding to the photoelectric detection module 4. The cylindrical plastic product enters the corresponding position of the inner cavity of the C-shaped frame 24 through the notch. The notch of the C-shaped frame 24 is now aligned with the output end of the belt conveyor 1. The clamping blocks of the radial clamping mechanism 25 simultaneously expand and contract radially, thereby clamping and positioning the cylindrical plastic product at the center of the inner cavity of the C-shaped frame 24.

[0038] The support drive 21 is operated again, transferring the grasped tubular plastic product to the trimming station. The radial sliding motion of the three sliding bases 34 is adjusted according to the outer diameter and wall thickness of the tubular plastic product, so that the top cutter head 36 faces the top surface of the tube opening, the blade of the outer edge cutter head 37 faces the outer wall of the tube opening of the plastic product, and the blade of the inner edge cutter head 37 faces the inner wall of the tube opening of the plastic product.

[0039] The top of the bracket 31 descends, while the rotary motor 32 drives the turntable 33 to rotate at high speed until the top cutter head 36 comes into contact with the top edge of the plastic product tube, completing the trimming of the tube end of the plastic product. The top of the bracket 31 then ascends, and the support drive 21 rotates, causing the next grasped plastic workpiece to be transferred to the trimming station. Simultaneously, the plastic product that has been transferred to the belt conveyor 1 and has completed the tube end trimming process is released back onto the belt conveyor 1.

[0040] See Figure 3 The radial clamping mechanism 25 comprises a connecting frame 251 with its top end fixed to the C-shaped frame 24, a second telescopic cylinder 252 with its cylinder body fixed to the outer wall of the bottom end of the connecting frame 251 and extending radially along the C-shaped frame 24, and an arc-shaped clamping plate 253 fixed to the end of the piston rod of the second telescopic cylinder 252. Specifically, the three second telescopic cylinders 252 extend synchronously, allowing the three arc-shaped clamping plates 253 to clamp and secure the tubular plastic product in the center of the inner cavity of the C-shaped frame 24.

[0041] In order to prevent the arc-shaped clamping plate 253 from causing damage and indentation to the outer wall of the cylindrical plastic product, a rubber pad 254 is attached to the inner peripheral wall of the arc-shaped clamping plate 253.

[0042] See Figure 4 The bracket 31 includes a base 311 fixed to the ground, an outer sleeve 312 fixed to the bottom surface of the base 311 and extending vertically, an inner sleeve 313 slidably mounted within the inner cavity of the outer sleeve 312, a horizontal beam 314 with one end fixed to the top of the inner sleeve 313 and extending horizontally, a telescopic cylinder 316 with a cylinder body fixed vertically to the outer wall of the outer sleeve 312 and a piston rod top fixedly connected to the horizontal beam 314, a support plate 315 fixed to the free end of the horizontal beam 314, and a transmission shaft 317 rotatably mounted at the top of the support plate 315. The rotary motor 32 is fixed to the top surface of the support plate 315, and the power output shaft of the rotary motor 32 is fixedly connected to the top of the transmission shaft 317. The center of the top surface of the turntable 33 is fixed to the bottom end of the transmission shaft 317. In other words, when the telescopic cylinder 316 is extended or retracted, the inner sleeve 313 moves up and down relative to the outer sleeve 314, causing the horizontal beam 314 to achieve a lifting motion.

[0043] See Figure 5-6The turntable 33 is provided with three radially extending sliding grooves 331 evenly distributed along the circumference corresponding to the outer edge of the bottom end of the transmission shaft 317. The top surface of the turntable 33 is provided with guide rails 332 in parallel at positions on both sides of the sliding groove 331. The sliding base 34 includes a slider 341 that is slidably mounted in the sliding groove 331, a mounting plate 343 fixed to the bottom end of the slider 341, and side plates 344 fixed on both sides of the middle of the slider 341. The bottom surface of the side plate 344 is provided with a card groove 345 that is slidably engaged with the guide rail 332. The top of the top surface cutting head 36, the outer edge cutting head 37 and the inner edge cutting head 38 are respectively detachably fixedly connected to the mounting plate 343. The top surface of the turntable 33 is provided with a radial transmission member 35 that drives the slider 341 to slide along the sliding groove 331.

[0044] See Figure 7 The radial transmission member 35 includes supports 351 fixed to the top surface of the turntable 33 and located at both ends of the chute 331, screw rods 352 rotatably mounted on the supports 351 at both ends, and a radial motor 353 fixed to the supports 351, with the power output shaft fixedly connected to the ends of the screw rods 352. A threaded sleeve 342, which is threadably coupled to the screw rod 352, is fixedly mounted on the top of the slider 341. In other words, the radial motor 353 drives the screw rod 352 to rotate, thereby enabling the slider 341 to slide radially along the chute 331 via the threaded sleeve 342.

[0045] See Figure 2 The supporting drive member 21 includes a platform 211, legs 212 fixed to the four corners of the bottom surface of the platform 211, a shaft 214 with its bottom end rotatably mounted in the center of the platform 211, and a swing motor 213 fixed to the bottom surface of the platform 211, with its power output shaft drivingly connected to the bottom end of the shaft 214. The bottom center of the connecting plate 22 is connected to the top end of the shaft 214. The swing motor 213 drives the connecting plate 22 to rotate through the shaft 214.

[0046] In order to avoid friction between the clamped and fixed plastic products and the belt surface of the belt conveyor 1 when the plastic products are rotated horizontally, and also to enable the plastic products to smoothly cross the frame of the belt conveyor 1, a telescopic cylinder 215 is vertically fixed to the inner cavity of the top of the shaft cylinder 214, and a connecting column 216 is fixed to the top of the piston rod of the telescopic cylinder 215. A guide rod 217 is vertically fixed to the outer edge of the top surface of the shaft cylinder 214, and the outer edge of the bottom end of the connecting column 216 is matched with the guide rod 217 in a vertical sliding sleeve, and the center of the bottom surface of the connecting plate 22 is fixedly connected to the top of the connecting column 216. That is, before the swing motor 213 drives the connecting plate 22 to rotate through the shaft cylinder 214, the piston rod of the telescopic cylinder 215 is extended, so that the connecting column 216 moves upward relative to the shaft cylinder 214 under the guidance of the guide rod 217, thereby causing the connecting plate 22, the swing arm 23, the C-shaped frame 24 and the clamped plastic product to be lifted synchronously, so that the plastic product will not rub against the belt surface of the belt conveyor 1 when swinging, and can also smoothly cross the frame of the belt conveyor 1.

[0047] The tops of the top cutter head 36, outer edge cutter head 37, and inner edge cutter head 38 are fixed to the corresponding mounting plate 343 with bolts. This facilitates timely replacement of worn cutter heads. In addition, when the mouth of the cylindrical plastic product presents an outward expansion or inward contraction shape, it is also convenient to replace the cutter heads with the opposite inclinations.

[0048] Among them, the determination of the processing position of the plastic product can be achieved by installing a photoelectric sensor; the size of the cylindrical plastic product can be achieved by installing a laser rangefinder, an ultrasonic rangefinder, a lidar or a laser scanner and other equipment, and its signal input end is associated with the control end of the radial motor 353 and the telescopic cylinder 252 through a controller to improve the level of automation control of the equipment.
