Description

Technical Field

[0001] This invention relates to the field of testing equipment for plastic container production, and in particular to an automatic thickness measuring device for the production of plastic buckets. Background Technology

[0002] Currently, in the production of square plastic buckets, a rotary ultrasonic thickness measurement method is commonly used to detect the uniformity of wall thickness. This method involves rotating the bucket on a turntable and scanning the outer wall with an external probe, effectively achieving non-contact continuous wall thickness measurement and meeting the quality inspection requirements of mass production. Existing testing equipment mostly uses a fixed clamping structure with a fixed-point probe to complete the testing operation. The process is relatively mature and can meet the basic wall thickness testing needs of conventional single-size plastic buckets, and is widely used in the quality inspection stage of plastic blow molding production lines.

[0003] Existing testing equipment suffers from poor tooling versatility, with most clamping and pressing structures being fixed, making it unsuitable for rapid changeover testing of square barrels of different sizes and heights. Furthermore, traditional rigid clamping creates blind spots by completely obscuring the barrel wall, and the lack of a retraction mechanism in fixed clamping systems can lead to incomplete testing. In addition, conventional testing processes are independent and fragmented, lacking a mechanically linked cleaning structure. Impurities on the outer wall can easily cause poor ultrasonic coupling and data fluctuations, and a single probe feed method makes it difficult to achieve uniform scanning across the entire surface. Therefore, an automatic thickness measuring device for plastic barrel production is proposed. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This automatic thickness measuring device for plastic bucket production features an adjustable clamping and clearance mechanism and an adaptive top pressing mechanism. Through worm gear and threaded sleeve transmission, the clamping distance is infinitely adjustable, enabling it to accommodate square plastic buckets of different cross-sectional sizes and heights for clamping and inspection. No special tooling replacement is required, significantly reducing production line changeover and equipment procurement costs. The clamping mechanism automatically retracts as the turntable rotates to the measuring and cleaning mechanism, with the top pressing mechanism providing axial clamping and limiting throughout the process. During retraction and inspection, the remaining clamping claws maintain centering constraint, effectively eliminating blind spots in wall thickness detection caused by the clamping structure. This also prevents bucket rotation from shifting or tipping, ensuring both positioning stability and inspection completeness.

[0016] 2. This automatic thickness measuring device for plastic bucket production integrates lifting, lateral feeding, and outer wall cleaning linkage structures through a measuring and cleaning mechanism. During the vertical downward movement of the detection head, the cleaning rod is synchronously driven to rotate by gears and racks, and the mechanical linkage synchronously removes burrs, dust, and impurities from the outer wall of the bucket. There is no need to add separate cleaning drive and control programs, which improves the coupling conditions of the ultrasonic probe and reduces the probability of wall thickness data jumps and false detections. The lifting frame, together with the lateral threaded rod, drives the detection head to complete continuous scanning of the entire surface, and the turntable intermittently rotates to complete full coverage detection of all four sides in sequence.

Plastic bucket body. Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] like Figure 1 - Figure 8As shown, an automatic thickness measuring device for plastic bucket production includes a detection platform 1 and a plastic bucket body 5. The upper surface of the detection platform 1 is provided with a clamping and clearance mechanism 2 for clamping the plastic bucket body 5. A pressing mechanism 3 for pressing and fixing the plastic bucket body 5 is fixedly connected to the upper surface of the detection platform 1. A measuring and cleaning mechanism 4 for measuring the thickness of the plastic bucket body 5 is fixedly connected to the upper surface of the detection platform 1. After the plastic bucket body 5 is fixed by the clamping and clearance mechanism 2, it is pressed and fixed by the pressing mechanism 3. The measuring and cleaning mechanism 4 is used to measure the thickness of the plastic bucket body 5 after it is fixed by the clamping and clearance mechanism 2 and the pressing mechanism 3. During the thickness measurement process, the clamping and clearance mechanism 2 automatically clears the way.

[0021] In this embodiment, the clamping and avoidance mechanism 2 includes a rotating platform 201 rotatably connected inside the detection table 1. A fixed pusher 202 is fixedly connected inside the rotating platform 201. A rotating plate 203 is rotatably connected inside the rotating platform 201. A communicating groove 204 is formed inside the rotating platform 201. A first limiting groove 205 is formed inside the rotating platform 201. A first sliding frame 206 and a second sliding frame 217 are slidably connected inside the first limiting groove 205. A flipping clamping plate 207 is rotatably connected inside the first sliding frame 206. A T-shaped push rod 208 is slidably connected inside the sliding frame 206. A spherical slider 209 is fixedly connected to the bottom end of the T-shaped push rod 208. A first spring 210 is sleeved on the outer surface of the T-shaped push rod 208. A first rotation adjustment rod 213 is rotatably connected inside the rotating table 201. A threaded sleeve rod 211 is slidably connected to the outer surface of the first rotation adjustment rod 213. A first moving plate 212 is rotatably connected to the outer surface of the threaded sleeve rod 211. A first transmission belt 214 is drively connected to the outer surface of the first rotation adjustment rod 213. The rotating plate 212... The interior of the 03 has an arc-shaped limiting groove 215 and a fan-shaped groove 216. A first connecting rod 218 is fixedly connected to one side of the second sliding frame 217. A second moving plate 219 is fixedly connected to one end of the first connecting rod 218. A second rotating adjusting rod 220 is rotatably connected to the bottom end of the fixed push platform 202. A worm gear 221 is fixedly connected to the outer surface of the second rotating adjusting rod 220. A worm wheel 222 is fixedly connected to the outer surface of the bottom end of the rotating plate 203. A flip clamping plate 207 is slidably connected inside the T-shaped push rod 208. A threaded sleeve 2... 11. The threaded connection is inside the first sliding frame 206. The spherical slider 209 slides on the upper surface of the fixed push table 202. The worm gear 222 meshes with the worm 221. The second rotating adjustment rod 220 is rotatably connected inside the rotating table 201. The second moving plate 219 and the first moving plate 212 are slidably connected inside the arc-shaped limiting groove 215. The two threaded sleeve rods 211 are connected by the first transmission belt 214. The first transmission belt 214 passes through the connecting groove 204. The side of the fixed push table 202 near the measuring and cleaning mechanism 4 is concave.

[0022] Specifically, the rotating table 201 is equipped with a worm gear 221 and a worm wheel 222. Rotating the second rotation adjustment rod 220 drives the worm gear 221 and worm wheel 222 to rotate. The worm wheel 222 drives the rotating plate 203 to rotate, synchronously driving multiple sets of first moving plates 212 and second moving plates 219 to slide along the arc-shaped limiting groove 215. While sliding, it pushes the threaded sleeve rod 211 and the first connecting rod 218 to move, thereby driving the first sliding frame 206 and the second sliding frame 217 to move, thus passing through the upper first... The sliding frame 217 clamps the plastic bucket body 5. Before clamping, the first rotation adjustment rod 213 is rotated to drive the threaded sleeve rod 211 to rotate. While the threaded sleeve rod 211 is rotating, the position of the first sliding frame 206 is adjusted to accommodate plastic buckets of different cross-sectional sizes. After clamping, the clamping plate 207 is flipped to hold the side wall of the bucket body, and the pressing mechanism 3 is used to lock the rotation measurement. When the side wall to be measured is rotated to the testing station, the corresponding spherical slider 209 moves to the lower position of the fixed push table 202, and then the first spring 2 10. Pushing the T-shaped push rod 208 downwards, the flip clamping plate 207 is driven to rotate and retract, and the remaining three sets of clamping components continue to clamp; after the test is completed, when the spherical slider 209 moves from the low position to the high position of the fixed push table 202 during rotation, the flip clamping plate 207 is pushed upwards by the T-shaped push rod 208 to rotate and reset the clamping, and the turntable switches to the next test surface. The worm gear 221 and worm wheel 222 achieve the function of clamping the plastic bucket body 5 by rotating the first rotation. The adjusting rod 213 synchronously adjusts the clamping position on the opposite side. A single tooling set is compatible with various sizes of square barrels, eliminating the tooling change process and reducing the changeover cost of the production line. Only one side of the flip clamping plate 207 automatically retracts with the rotation angle, while the other flip clamping plates 207 are continuously centered and limited, eliminating the detection blind spot caused by clamping obstruction. At the same time, it prevents the workpiece from shaking or tipping due to the top limit alone. The first spring 210 provides flexible clamping buffer. The plastic barrel body 5 is clamped without indentation or extrusion deformation, ensuring the appearance quality of the workpiece.

[0023] In this embodiment, the pressing mechanism 3 includes a fixed rod 301 fixedly connected to the upper surface of the testing platform 1. A top plate 302 is fixedly connected to the top end of the fixed rod 301. A pressing telescopic rod 303 is fixedly connected to the lower surface of the top plate 302. A rotating pressing disc 304 is rotatably connected to the bottom end of the pressing telescopic rod 303. A connecting telescopic rod 305 is fixedly connected to the lower surface of the rotating pressing disc 304. A fixing plate 307 is fixedly connected to the bottom end of the connecting telescopic rod 305. A pressing spring 306 is sleeved on the outer surface of the connecting telescopic rod 305. The fixing plate 307... The interior is provided with a second limiting groove 308, and a movable top block 309 is slidably connected inside the second limiting groove 308. A second connecting rod 310 is rotatably connected inside the movable top block 309. The top plate 302 and the rotating pressing plate 304 are connected by a pressing telescopic rod 303. The rotating pressing plate 304 and the movable top block 309 are rotatably connected by the second connecting rod 310. The fixed plate 307 and the rotating pressing plate 304 are connected by a connecting telescopic rod 305. The pressing spring 306 is disposed between the rotating pressing plate 304 and the fixed plate 307.

[0024] Specifically, the pressing telescopic rod 303 below the top plate 302 drives the rotating pressing plate 304 to feed downwards, connecting the telescopic rod 305 and the pressing spring 306 to drive the bottom fixing plate 307 to press down and fit against the barrel opening; the moving top block 309 inside the fixing plate 307 adapts to the contour of barrel openings of different diameters through the second connecting rod 310 to achieve contour pressing; the rotating pressing plate 304 can rotate synchronously with the bottom turntable, continuously applying axial pressing constraint to the workpiece throughout the process; regardless of whether the clamping and avoidance mechanism 2 clamps and retracts on one side or resets, the pressing... Mechanism 3 always remains locked under downward pressure, restricting the workpiece from moving up and down or tilting axially. The adaptive contouring structure of the moving top block 309 can match plastic buckets of different heights and opening sizes. The axial clamping force is consistently stable. When the clamping and clearance mechanism 2 clamps and retracts on one side, the pressing mechanism 3 maintains axial clamping throughout the process, compensating for the positioning defects after one side is released, effectively preventing the workpiece from tilting or shifting. The pressing spring 306 provides elastic buffering, so the pressing process will not damage the thin wall of the bucket opening, and the whole rotates synchronously with the workpiece, without relative sliding and scratching the end face of the bucket opening.

[0025] In this embodiment, the measuring and cleaning mechanism 4 includes a fixed platform 401 fixedly connected to the upper surface of the detection platform 1. A third sliding frame 402 is slidably connected to the upper surface of the fixed platform 401. A lifting frame 403 is slidably connected inside the third sliding frame 402. A motor 405 is fixedly connected to the upper surface of the lifting frame 403. A threaded rod 406 is fixedly connected to the output end of the motor 405. A detection head 407 is threadedly connected to the outer surface of the threaded rod 406. A cleaning rod 408 and a rotating rod 411 are rotatably connected inside the lifting frame 403. The outer surface of the 08 is fixedly connected to a first cleaning drive wheel 409, and the outer surface of the first cleaning drive wheel 409 is connected to a second drive belt 410. The outer surface of the rotating rod 411 is fixedly connected to a second cleaning drive wheel 412 and a gear 413. The side surface of the third sliding frame 402 is fixedly connected to a rack 404, and the gear 413 and rack 404 mesh together. The first cleaning drive wheel 409 and the second cleaning drive wheel 412 are connected by the second drive belt 410. The detection head 407 is slidably connected to the upper surface of the lifting frame 403.

[0026] Specifically, the third sliding frame 402 above the fixed platform 401 achieves the overall lateral displacement of the mechanism, the lifting frame 403 moves up and down in the vertical direction, and the motor 405 drives the threaded rod 406 to move the detection head 407 left and right to complete the full-surface scanning of the barrel wall; the side rack 404 of the lifting frame 403 meshes with the gear 413 for transmission, and when the lifting frame 403 moves downward, it synchronously drives the rotating rod 411 and the second cleaning transmission wheel 412 to rotate, which drives the first cleaning transmission wheel 409 to rotate through the second transmission belt 410, driving the cleaning rod 408 to rotate and clean the dust on the outer wall of the barrel. The cleaning components detach from the barrel wall simultaneously when the lifting frame 403 is raised. The cleaning action and the descent action of the detection head 407 are mechanically linked. The vertical lifting of the lifting frame 403, combined with the lateral movement of the third sliding frame 402, enables a complete sweep of the entire square barrel, eliminating blind spots in the vertical and horizontal directions. The wall thickness data is complete and comprehensive. The mechanical linkage of lifting displacement for cleaning simultaneously removes impurities from the outer wall, reducing data fluctuations and false detections, and improving measurement accuracy. The cleaning and detection share a single lifting drive component, simplifying the overall structure and reducing equipment production costs and the probability of failure.

[0027] It should be noted that this invention is an automatic thickness measuring device for plastic bucket production. In use: the plastic bucket body 5 is placed at the center of the rotating table 201. Rotating the second rotation adjustment rod 220 drives the worm gear 221 and worm wheel 222 to mesh and transmit power, thereby pushing the rotating plate 203 to rotate. The second moving plate 219 moves to clamp and limit the plastic bucket body 5. Rotating the first rotation adjustment rod 213, through the first transmission belt 214, links each set of threaded sleeve rods 211 to rotate. When the threaded sleeve rods 211 rotate, they push the first sliding frame 206 to move, thereby adjusting the adjacent sides of the first sliding frame 206 and the second sliding frame 217. At different positions, plastic bucket bodies 5 of different shapes and sizes are adapted to complete the synchronous centering clamping of four sets of flipping clamping plates 207; then, pressing the telescopic rod 303 drives the rotating pressing plate 304 to feed downwards, connecting the telescopic rod 305 and the pressing spring 306 to drive the fixed plate 307 to press down, and the moving top block 309 and the second connecting rod 310 adaptively fit the opening of the plastic bucket body 5 of different diameters, relying on the pressing spring 306 to form an elastic contour clamping, applying axial limit to the plastic bucket body 5 throughout the process to prevent the workpiece from moving up and down. After the equipment starts, the rotating table 201 drives the plastic bucket body 5 to rotate as a whole. When the side wall of the plastic bucket body 5 to be measured rotates to the measuring and cleaning machine When the structure is in the inspection station 4, the corresponding spherical slider 209 slides along the fixed push table 202 at a low position. The first spring 210 pushes the T-shaped push rod 208 to move down, causing the flip clamping plate 207 to rotate and move back slightly. The other three sets of flip clamping plates 207 continue to clamp and maintain centering, eliminating clamping blind spots. The synchronous lifting frame 403 moves vertically downward along the third sliding frame 402 for a certain distance. The rack 404 and gear 413 mesh to drive the rotating rod 411 and the second cleaning transmission wheel 412 to rotate. The second transmission belt 410 drives the cleaning rod 408 to rotate, synchronously cleaning the dust and debris on the outer wall of the plastic bucket body 5. After descending to the bottom, the motor 405 The drive threaded rod 406 drives the detection head 407 to move laterally, completing the full wall thickness scan of this side. After the side wall is inspected, the lifting frame 403 lifts up, causing the cleaning rod 408 to detach from the barrel wall. The rotating table 201 continues to rotate, and the spherical slider 209 is lifted along the track of the fixed push table 202. The flip clamping plate 207 rotates back to reset and re-clamp the plastic barrel body 5. The cycle is repeated to complete the full coverage inspection of the four sides of the plastic barrel body 5. The entire operation relies on the mechanical structure to achieve clamping distance adjustment, top contour pressing, automatic corner avoidance, downward linkage cleaning, and horizontal and vertical composite scanning linkage operation, without the need for multiple independent electrical control systems to control the actions of each mechanism separately.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
