Technical Field
[0001] The utility model relates to the technical field of plastic bucket diameter detection, in particular to a sampling diameter detection device for plastic bucket manufacturing. Background Technique
[0002] After the production of plastic buckets, detecting the diameter of plastic buckets is a crucial part of the quality control process. By detecting the diameter, it can be ensured whether the plastic buckets meet the specified size requirements, and avoid insufficient or excessive capacity caused by size deviation, thus affecting the use effect and user experience of the products.
[0003] A Chinese patent with the publication number CN207423146U discloses a plastic bucket radius detection device, including a first micro-motor, a detection main body and a connection main body. The lower end surface of the first micro-motor is fixedly connected with a protective chassis. The center position of the lower end surface of the protective chassis is fixedly connected with a first electric telescopic rod. The center position of the lower end surface of the first electric telescopic rod is fixedly connected with a connecting support rod. The bottom end of the connecting support rod is fixedly connected with a second micro-motor. There are four groups of the detection main bodies, and they are all fixedly connected to the four corners of the outer end surface of the second micro-motor. A second electric telescopic rod is fixedly connected inside the detection main body. The utility model can improve the practical performance of the device and also improve the convenience of the device by providing the first micro-motor, the detection main body and the connection main body.
[0004] The above-mentioned plastic bucket radius detection device still has some problems in use. When detecting the diameter of the plastic bucket, it can only detect the inner diameter of the bucket body and cannot detect the outer diameter of the bucket body. Only detecting the inner diameter cannot comprehensively evaluate the geometric dimensions of the plastic bucket. There will be problems such as uneven wall thickness, inconsistent shrinkage rate or mold wear during the production of plastic buckets, and these problems are reflected in the outer diameter. Only detecting the inner diameter may miss these problems, resulting in unqualified products flowing into the market. Therefore, a sampling diameter detection device for plastic bucket manufacturing is proposed to solve the above problems. Content of the Utility Model
[0005] In order to make up for the deficiencies of the prior art and solve the problems raised in the above background technique, the utility model proposes a sampling diameter detection device for plastic bucket manufacturing.
[0006] The technical solution adopted by the utility model to solve its technical problems is as follows: A sampling diameter detection device for manufacturing plastic barrels of the utility model includes a base, a fixed frame is installed on the base, a first pneumatic cylinder is installed on the fixed frame, a first pneumatic rod is assembled at the acting end of the first pneumatic cylinder, a cross plate is fixedly connected to the bottom end of the first pneumatic rod, a groove is opened on the cross plate, a first bidirectional lead screw is rotatably installed in the groove, a first motor is installed on one side wall of the cross plate, the output end of the first motor is connected to one end of the first bidirectional lead screw, two movable blocks are sleeved on the first bidirectional lead screw, and the movable blocks are arranged in the groove, radius measuring rods are fixedly connected to the bottom sides of the two movable blocks, a first scale marking is assembled on the outer side wall of the cross plate, two rod holes are opened on the fixed frame, limiting rods are inserted into the two rod holes, and the two limiting rods are respectively located on both sides of the first pneumatic cylinder, and the bottom ends of the limiting rods are fixedly connected to the cross plate. When detecting the diameter of the plastic barrel, start the first pneumatic cylinder to make the cross plate drive the radius measuring rods to move down until they reach the inside of the barrel port, then the first pneumatic cylinder stops working. Start the first motor to make the first bidirectional lead screw rotate, forcing the two movable blocks to drive the two radius measuring rods to move away from each other until the radius measuring rods expand to fit the inner wall of the barrel, then the first motor stops working. Align with the first scale marking, the distance between the two radius measuring rods is the inner diameter of the barrel. Then, through the operation of the first pneumatic cylinder, make the cross plate drive the radius measuring rods to move up until they contact the top side of the barrel port. Through the continuous operation of the first motor, make the two movable blocks drive the two radius measuring rods to continue to move away from each other until the side surfaces where the two radius measuring rods are close to each other move to the same vertical plane as the outer side wall of the barrel, the distance between the two radius measuring rods is the outer diameter of the barrel. By detecting the inner and outer diameters of the barrel, the geometric dimensions of the plastic barrel can be evaluated more comprehensively, avoiding the problem of the outer diameter that may be missed due to only detecting the inner diameter, such as the outer diameter deviation caused by uneven wall thickness, mold wear, etc. At the same time, the detection of the inner and outer diameters helps to more strictly control the quality of the plastic barrel, ensuring that each batch of products meets the established standards.
[0007] Preferably, a chute is formed on one side of the fixing frame, and a slider is arranged in the chute. A screw hole is formed on one side of the top of the fixing frame, and a threaded rod is rotatably assembled in the screw hole. The bottom end of the threaded rod is rotatably installed on the slider, and a hand wheel is fixedly connected to the top end of the threaded rod. A second pneumatic cylinder is installed on the slider, and a second pneumatic rod is assembled at the acting end of the second pneumatic cylinder. The other end of the second pneumatic rod is fixedly connected to a height measuring rod. A second scale marking is assembled on the outer side wall of the fixing frame. When measuring the height of the plastic bucket, first, the second pneumatic cylinder operates to drive the second pneumatic rod to move the height measuring rod above the port of the bucket body. Then, rotate the hand wheel to drive the threaded rod to drive the slider to move downward, and further drive the height measuring rod to move downward until the height measuring rod vertically moves downward to contact the top side wall of the port of the bucket body, and align it with the second scale marking, so that the height of the bucket body can be visually detected, and it can be accurately judged whether the height of the bucket body meets the standard.
[0008] Preferably, a rotating column is rotatably installed on the base, and a rotating disc is fixedly connected to the top end of the rotating column. A driven gear is sleeved on the bottom end of the rotating column. A limiting sleeve is sleeved on the rotating column. A limiting ring is fixedly connected to the top side of the base, and the limiting ring surrounds the rotating disc. A third motor is installed on the bottom side of the base, and a driving gear is installed at the output end of the third motor, and the driving gear meshes with the driven gear. During the detection process, the third motor operates to drive the driving gear to rotate, forcing the driven gear to drive the rotating column to rotate, and further driving the rotating disc to drive the clamped and fixed plastic bucket to rotate accordingly, so that the diameters of all directions of the plastic bucket can be detected by the radius measuring rod, avoiding measurement errors caused by irregular shapes or local deformations of the plastic bucket.
[0009] Preferably, a rectangular groove is formed on the rotating disc, and a second bidirectional lead screw is rotatably installed in the rectangular groove. Two moving blocks are sleeved on the second bidirectional lead screw. Clamping plates are fixedly connected to the top sides of the two moving blocks. Rubber pads are assembled on the clamping plates. A second motor is installed on the outer peripheral side of the rotating disc, and the output end of the second motor is connected to one end of the second bidirectional lead screw. When clamping and fixing the plastic bucket, the second motor operates to drive the second bidirectional lead screw to rotate, and further drive the two moving blocks to drive the two clamping plates to approach each other, so as to clamp and fix the plastic bucket, avoiding the phenomenon that the position of the plastic bucket shifts during the detection process. By setting the rubber pads, the friction force between the outer wall of the plastic bucket and the clamping plates can be increased, making the clamping and fixing of the plastic bucket more stable.
[0010] The beneficial effects of the present utility model are as follows:
[0011] When the present utility model detects the diameter of a plastic bucket, the first pneumatic cylinder is started. When the cross plate drives the radius measuring rod to move down to the inside of the bucket port, the first pneumatic cylinder stops working. The first motor is started to make the first bidirectional lead screw rotate, forcing the two movable blocks to drive the two radius measuring rods to move away from each other until the radius measuring rods expand outwards to fit the inner wall of the bucket. At this time, the first motor stops working. By aligning with the first scale mark, the distance between the two radius measuring rods is the inner diameter of the bucket. Then, through the operation of the first pneumatic cylinder, the cross plate drives the radius measuring rod to move up to contact the top side of the bucket port. By continuing the operation of the first motor, the two movable blocks drive the two radius measuring rods to continue moving away from each other until the side surfaces where the two radius measuring rods are close to each other move to the same vertical plane as the outer side wall of the bucket. The distance between the two radius measuring rods is the outer diameter of the bucket. Through the detection of the inner and outer diameters of the bucket, the geometric dimensions of the plastic bucket can be evaluated more comprehensively, avoiding the problem of the outer diameter that may be missed due to only detecting the inner diameter, such as the outer diameter deviation caused by uneven wall thickness, mold wear, etc. At the same time, the detection of the inner and outer diameters helps to more strictly control the quality of the plastic bucket and ensure that each batch of products meets the established standards.

[0022] Please refer to Figures 4-5 As shown in the figure, a rotating column 20 is rotatably installed on the base 1. The top end of the rotating column 20 is fixedly connected with a rotating disc 21. The bottom end of the rotating column 20 is sleeved with a driven gear 28.

[0024] Working principle: Since there are still some problems in the use of the above-mentioned plastic bucket radius detection device, when detecting the diameter of the plastic bucket, it can only detect the inner diameter of the bucket body and cannot detect the outer diameter of the bucket body. Only detecting the inner diameter cannot comprehensively evaluate the geometric dimensions of the plastic bucket. During the production process of the plastic bucket, there will be problems such as uneven wall thickness, inconsistent shrinkage rate, or mold wear. These problems are reflected in the outer diameter. Only detecting the inner diameter may miss these problems, resulting in unqualified products flowing into the market. Therefore, in response to the above problems, a sampling diameter detection device for plastic bucket manufacturing is proposed. When detecting the diameter of the plastic bucket, first, the plastic bucket to be detected is clamped and fixed. When clamping and fixing the plastic bucket, the plastic bucket to be detected is placed on the rotating disk 21. Through the operation of the second motor 24, the second bidirectional lead screw 23 rotates, and then the two moving blocks drive the two clamping plates 25 to approach each other, so as to clamp and fix the plastic bucket, avoiding the phenomenon of the plastic bucket shifting in position during the detection process. After clamping and fixing the plastic bucket to be detected, start the first pneumatic cylinder 3, so that the first pneumatic rod 4 drives the cross plate 5 to move vertically downward, and then the radius measuring rod 10 also moves downward accordingly. When the radius measuring rod 10 moves down into the bucket body port, the first pneumatic cylinder 3 stops operating. Start the first motor 8, so that the first bidirectional lead screw 7 rotates, forcing the two movable blocks 9 to drive the two radius measuring rods 10 to move away from each other until the radius measuring rods 10 expand outward to fit the inner wall of the bucket body. Then the first motor 8 stops operating. Align with the first scale marking 11, and the distance between the two radius measuring rods 10 is the inner diameter of the bucket body. Then, through the operation of the first pneumatic cylinder 3, the cross plate 5 drives the radius measuring rod 10 to move upward until it contacts the top side of the bucket body port. Through the continuous operation of the first motor 8, the first bidirectional lead screw 7 rotates, forcing the two movable blocks 9 to drive the two radius measuring rods 10 to continue moving away from each other until the side surfaces of the two radius measuring rods 10 that are close to each other move to the same vertical plane as the outer side wall of the bucket body. The distance between the two radius measuring rods 10 is the outer diameter of the bucket body. By detecting the inner and outer diameters of the bucket body, the geometric dimensions of the plastic bucket can be more comprehensively evaluated, avoiding the outer diameter problems that may be missed due to only detecting the inner diameter, such as outer diameter deviations caused by uneven wall thickness, mold wear, etc. At the same time, the detection of the inner and outer diameters helps to more strictly control the quality of the plastic bucket, ensuring that each batch of products meets the established standards. Through the operation of the third motor 30, the driving gear 31 rotates, forcing the driven gear 28 to drive the rotating column 20 to rotate, and then the rotating disk 21 drives the clamped and fixed plastic bucket to rotate accordingly, so that the diameters of all directions of the plastic bucket can be detected by the radius measuring rod 10, avoiding measurement errors caused by the irregular shape or local deformation of the plastic bucket.
