Description
Technical Field
[0001] The utility model relates to a detection device, in particular to a bottle blank downward pressing deviation correction detection device. Background Art
[0002] Preform deflection detection is widely used in PET bottle production lines in the beverage, food, cosmetics and other industries. This detection not only improves product quality, but also reduces material waste and improves the overall efficiency of the production line.
[0003] Preform deflection detection is an important part of the preform production process. Its main purpose is to ensure that the key parameters of the preform after forming, such as verticality and flatness, meet the quality requirements. The existing detection is to directly scan the preform through the detector, and then transmit it back to the computer to display the reaction results. However, when the detector directly scans the flatness of the bottle mouth above the preform, it is easily affected by the shaking caused by the movement of the preform, which may cause errors in the scanning test results. Utility Model Content

[0007] Furthermore, it further includes an adjusting mechanism, which includes a guiding plate, a carriage, a bolt and a limiting plate.

Detailed implementation mode
[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0019] A bottle preform pressing and deviation correcting detection device, as Figures 1-4 shown, includes a bracket 1, a mounting frame 2, a transmission assembly 3, a fixed frame 6, a rotating frame 7, a circular track 701, a motor 8, a sliding rod 10, an elastic member 11, a convex rod 12, a spherical joint 13, a pressing plate 14 and a detection mechanism. The mounting frame 2 is installed at the top of the bracket 1, and the mounting frame 2 plays a supporting role. The transmission assembly 3 is arranged on the mounting frame 2, and the transmission assembly 3 is used for transmitting the bottle preforms. Fixed frames 6 are symmetrically arranged on the front and rear sides of the top end of the mounting frame 2, and the fixed frames 6 are used for supporting and fixing. Circular tracks 701 are connected to both fixed frames 6. An opening is provided at the bottom end of each of the two circular tracks 701, and the opening presents an inverted V shape. A rotating frame 7 is arranged between the two circular tracks 701. The transmission assembly 3 is located below the rotating frame 7. The rotating frame 7 is rotatably connected to the fixed frame 6 through a connecting rod. A chute 9 is arranged on the rotating frame 7, and the chute 9 is evenly distributed along the circumference of the rotating frame 7. Convex rods 12 are slidably connected in the chutes 9. The convex rods 12 penetrate through the rotating frame 7 and are slidably connected to the circular tracks 701. A sliding rod 10 is connected to the middle of the convex rod 12. One end of the sliding rod 10 away from the convex rod 12 is connected to the pressing plate 14 through a spherical joint 13. The sliding rod 10 and the pressing plate 14 are hinged through the spherical joint 13, so that the pressing plate 14 can rotate three-dimensionally. An elastic member 11 is connected between the sliding rod 10 and the rotating frame 7. A motor 8 is arranged on the upper part of the front end of the fixed frame 6. The output shaft of the motor 8 is connected to the rotating frame 7 through a connecting rod. The motor 8 provides power for the rotating frame 7. A detection mechanism is installed at the top of the mounting frame 2, and the detection mechanism is used for detecting whether the bottle preforms are qualified.
[0020] As Figure 2 shown, the detection mechanism includes a housing 4 and a detector 5. The housing 4 is arranged in the middle of the mounting frame 2, and the mounting frame 2 penetrates through the housing 4. Detectors 5 are symmetrically arranged on the front and rear walls inside the housing 4, and can scan the bottle preforms for detection.
[0021] As Figure 5As shown in the figure, it further includes an adjusting mechanism. The adjusting mechanism includes a guide plate 15, a carriage 16, a bolt 17 and a limiting plate 18. Limiting plates 18 are symmetrically arranged on the front and rear sides of the top of the mounting bracket 2. The limiting plates 18 can limit the preforms. Guide plates 15 are symmetrically arranged at the front end and the rear end of the mounting bracket 2. Slide carriages 16 are slidably connected to the guide plates 15. The top of the slide carriage 16 is connected to the limiting plate 18. By sliding the slide carriage 16 on the guide plate 15, the distance between the two limiting plates 18 can be controlled. A threaded hole is provided on the slide carriage 16, and a bolt 17 is fitted to the threaded hole. The bolt 17 can control the movement of the slide carriage 16.
[0022] As Figure 5 shown in the figure, it further includes an arc plate 20. Arc plates 20 are connected to the left and right ends of the two limiting plates 18. The arc plate 20 is of an arc structure, which is beneficial to the transmission of the preforms.
[0023] As Figure 2 shown in the figure, it further includes a protrusion 19. The transmission assembly 3 is a belt conveyor. The protrusions 19 are installed at intervals on the front and rear sides of the conveyor belt of the belt conveyor.
[0024] The pressing plate 14 is made of rubber, which can prevent the mouth of the preform from being damaged.
[0025] Fix the entire preform pressing, deviation correction and detection device through the bracket 1, and connect the device to the production line. Before people use the device, the adjustment mechanism should be appropriately adjusted to prevent excessive front-back shaking when the preform moves. Place multiple preforms front and back between the protrusions 19 of the transmission component 3, and adjust the distance between the two limit plates 18 according to the size of the preform to limit the preform on both the front and back sides. During this process, loosen the bolt 17 on the carriage 16. At this time, the carriage 16 can slide on the guide plate 15. Push the carriage 16 to slide back and forth on the guide plate 15. The front-back sliding of the carriage 16 drives the limit plate 18 to move back and forth. Adjust the limit plate 18 until the preform can just pass through without front-back shaking. Tighten the bolt 17 to fix the carriage 16, and thus fix the position of the limit plate 18. After completion, turn on the production line and start the transmission component 3. Through the arc-shaped plate 20, the preforms on the production line can smoothly enter between the two limit plates 18. The output preforms are exactly located between the two protrusions 19. Start the motor 8. The motor 8 is used as a power component. The output shaft of the motor 8 drives the rotating frame 7 to rotate. The rotation of the rotating frame 7 drives the convex rod 12 to slide on the circular track 701. When the convex rod 12 approaches directly below the rotating frame 7, the convex rod 12 moves downward along the opening of the circular track 701. During this process, the elastic member 11 gradually returns from the compressed state. The convex rod 12 slides downward along the chute 9, driving the slide bar 10 to move downward. The spherical joint 13 at the bottom end of the slide bar 10 and the pressing plate 14 will also move downward accordingly. When the convex rod 12 rotates to directly below the rotating frame 7, the convex rod 12 separates from the circular track 701. At this time, the pressing plate 14 at the bottom end of the spherical joint 13 just presses down above the bottle mouth of the preform. The pressing plate 14 is made of rubber and is square-shaped, which can completely cover the bottle mouth of the preform to fix the preform and prevent the preform from shaking. At this time, the detector 5 detects the flatness of the bottle mouth. After the detector 5 finishes detecting, the rotating frame 7 rotates to drive the convex rod 12 to slide upward along the circular track 701. During this process, the convex rod 12 moves upward along the chute 9 to the top of the chute 9. The slide bar 10 drives the spherical joint 13 to move upward, and the elastic member 11 is compressed accordingly. The pressing plate 14 disengages from the preform. Driven by the transmission component 3, the preform passes through the outer shell 4 and moves between the arc-shaped plates 20 at the right end, and then leaves the mounting bracket 2.
