Abstract
Description
Technical Field
[0001] This utility model relates to the field of detection device technology, specifically a detection device for high-barrier polyethylene bottles. Background Technology
[0002] High-barrier polyethylene bottles are plastic packaging containers manufactured using a special process. During product transportation, the bottles are subjected to various pressures. If the bottle's pressure resistance is insufficient, it is easy for it to deform. Therefore, a pressure resistance testing device is needed.
[0003] One existing high-barrier polyethylene bottle testing device typically involves placing the polyethylene bottle to be tested in a specific position, activating an electric telescopic rod to push a pressure plate to apply pressure to the bottle, and monitoring pressure changes in real time using a pressure sensor. When the bottle deforms or ruptures, the pressure value at that moment is recorded to assess the bottle's pressure resistance, thereby achieving the testing of the bottle's pressure resistance performance.
[0004] However, the above-mentioned detection device still has some problems. In practical applications, the detection device in the prior art cannot automatically clamp and fix the bottle, and additional operations are required to clamp the bottle, which will reduce the detection efficiency of the bottle. Therefore, a high-barrier polyethylene bottle detection device is proposed to address the above problems. Utility Model Content
[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background technology, this utility model proposes a high-barrier polyethylene bottle detection device.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A high-barrier polyethylene bottle testing device of this utility model includes a workbench. Four placement cavities are installed directly above the workbench. Electrode plates are installed inside the bottom side of each placement cavity. A sliding groove is formed on the inner side of each placement cavity. Support rods are fixedly connected between the two sides of the sliding groove. Sliding blocks are slidably installed on the outer side of the support rods. The sliding blocks are slidably installed inside the sliding grooves. A tension spring is fixedly connected between the sliding blocks and the sliding grooves. The tension spring is sleeved on the outer side of the support rods and has high elasticity. A support plate is installed between the sliding blocks. The radius of the plate is less than or equal to the inner diameter of the placement cavity. An electrode plate is installed on the bottom side of the plate, and the electrode plate is located directly above the electrode plate. Indicator lights are installed on the outer side of the placement cavity. Two telescopic rods are symmetrically installed on the outer side of the placement cavity. The working end of the telescopic rod extends into the interior of the placement cavity and is fitted with a clamping plate. When the bottle is placed on the plate, the plate moves downward due to external force and the weight of the bottle itself. The tension spring is stretched, causing the electrode plate to contact the electrode plate. The indicator light illuminates and transmits a signal to the control panel. The control panel then activates the telescopic rods to extend, automatically clamping and fixing the bottle, thus improving the efficiency of the detection.
[0007] Preferably, a rotating shaft is rotatably mounted on the top side of the workbench, and a support plate is mounted on the top side of the rotating shaft. The placement cavities are equidistantly mounted on the top side of the support plate. A groove is formed inside the workbench, and the bottom end of the rotating shaft passes through the groove. A gear is mounted on the outer side of the bottom end of the rotating shaft. A rectangular groove is formed on the top side of the groove, and a slider is slidably mounted inside the rectangular groove. A through hole is formed on one side of the workbench through the groove, and a cylinder is installed inside the through hole. The working end of the cylinder is fixedly connected to one side of the slider. A rack is mounted on the top side of the slider, and the rack meshes with the gear. The cylinder drives the slider and rack to slide in the rectangular groove and mesh with the gear to realize the rotation control of the rotating shaft. The rotation of the rotating shaft can drive the support plate and the bottles in the placement cavity to move, realizing continuous detection operation.
[0008] Preferably, four support columns are equidistantly installed on the top side of the workbench, outside the rotating shaft. A trigger switch is installed on the outside of the support columns, and a connecting rod is installed on the outside of the rotating shaft. A squeezing plate is installed at one end of the connecting rod. The squeezing plate is made of rubber. When the squeezing plate moves, it presses one of the trigger switches. When the rotating shaft rotates, it drives the connecting rod and the squeezing plate to move. When the squeezing plate presses one of the trigger switches, a placement cavity is located directly below the squeezing plate, thereby achieving precise positioning of the bottle and improving the accuracy of bottle detection.
[0009] Preferably, a fixed frame is installed on the top side of the workbench, a hydraulic cylinder is installed on the top side of the fixed frame, a pressing plate is installed on the actuating end of the hydraulic cylinder, and a rubber pad is fitted on the bottom side of the pressing plate. The pressing plate is used to test the pressure resistance of the bottle, and the rubber pad is used to protect the bottle from damage.
[0010] Preferably, a circular groove is formed inside the bottom side of the pressing plate, and a pressure sensor is installed inside the circular groove. The pressure sensor is used to monitor the pressure of the pressing plate on the bottle to determine whether the bottle is qualified.
[0011] Preferably, a control panel is installed on one side of the workbench. The electrode plate, electrode sheet, indicator light, and power supply are connected as a circuit. The indicator light is connected to the control panel via a signal line. The control panel can be used to control the extension operation of the telescopic rod. The control panel is electrically connected to the trigger switch, pressure sensor, and telescopic rod. The control panel is used for signal transmission to the trigger switch and pressure sensor, as well as for the switching operation of the hydraulic cylinder and the pneumatic cylinder, and the retraction operation of the telescopic rod, thereby improving the automation level of the device.
[0012] The advantages of this utility model are: 1. Due to the bottle's own weight and the external force applied during placement, the support plate moves downward, causing the sliding block to slide down the support rod within the groove. The tension spring is stretched, and as the support plate descends, the electrode plate gradually approaches the electrode plate until they contact each other, illuminating the indicator light. Simultaneously, the signal from the indicator light is transmitted to the control panel via a signal line. The control panel then activates the extension rod, extending its active end to push the clamping plate to hold and fix the bottle. This achieves automated bottle fixing, improves detection efficiency, and reduces the time required to switch the clamping components on and off. 2. The rotating shaft of this utility model causes the support plate to rotate, and the placement cavity and the bottle in the cavity also begin to rotate. The connecting rod and the extrusion plate also move together. When the extrusion plate moves to contact a trigger switch on the outside of the support column and presses the trigger switch, the trigger switch transmits a signal to the control panel. After receiving the signal, the control panel controls the cylinder to stop working. At this time, one placement cavity is located directly below the pressing plate, realizing the precise positioning of the bottle and preparing for subsequent accurate pressure resistance testing.

A [missing information - likely a device name] is installed on one side of the workbench 1. Control panel 32; In practical applications, existing detection devices cannot automatically clamp and fix bottles, requiring additional operations to clamp the bottles, which reduces the detection efficiency. When high-barrier polyethylene bottles need to be detected, the bottle is first placed on the tray 8. Due to the bottle's own weight and the external force applied during placement, the tray 8 moves downward, causing the sliding block 6 to slide downward along the support rod 5 in the slide groove 4. The tension spring 7 is stretched. As the tray 8 descends, the electrode plate 9 gradually approaches the electrode plate 3 until the two contact. At this time, the circuit formed by the electrode plate 3, electrode plate 9, indicator light 10, and power supply is connected, and the indicator light 10 lights up. At the same time, the signal of the indicator light 10 lighting up is transmitted to the control panel 32 through the signal line. The control panel 32 activates the extension rod 11 to extend. The working end of the extension rod 11 extends, pushing the clamping plate 12 to clamp and fix the bottle, realizing automated bottle fixing, improving detection efficiency, and reducing the time for switching the clamping components.
[0018] Please see Figure 1 , 2 As shown in Figures 4 and 5, a rotating shaft 13 is rotatably mounted on the top side of the workbench 1, and a support plate 14 is mounted on the top side of the rotating shaft 13. The placement cavities 2 are respectively installed at equal intervals on the top side of the support plate 14. A groove 15 is opened inside the workbench 1. The bottom end of the rotating shaft 13 is set through the groove 15. A gear 16 is installed on the outer side of the bottom end of the rotating shaft 13. A rectangular groove 17 is opened on the top side of the groove 15. A slider 18 is slidably installed inside the rectangular groove 17. A through hole 19 is opened on one side of the workbench 1 through the groove 15. A cylinder 20 is installed inside the through hole 19. The working end of the cylinder 20 is fixedly connected to one side of the slider 18. A rack 21 is installed on the top side of the slider 18, and the rack 21 meshes with the gear 16. Four support columns 22 are equidistantly installed on the top side of the workbench 1, outside the rotating shaft 13. A trigger switch 23 is installed on the outside of the support columns 22. A connecting rod 24 is installed on the outside of the rotating shaft 13. A pressing plate 25 is installed at one end of the connecting rod 24. The pressing plate 25 is made of rubber. When the pressing plate 25 moves, it will press one of the trigger switches 23. A fixed frame 26 is installed on the top side of the workbench 1, a hydraulic cylinder 27 is installed on the top side of the fixed frame 26, a pressing plate 28 is installed on the working end of the hydraulic cylinder 27, and a rubber pad 29 is fitted on the bottom side of the pressing plate 28. A circular groove 30 is formed inside the bottom side of the pressing plate 28. A pressure sensor 31 is installed inside the circular groove 30 to monitor the pressure of the pressing plate 28 on the bottle. During operation, the bottle will be subjected to various pressures during transportation. If the bottle's pressure resistance is insufficient, it will easily deform. Therefore, a pressure resistance testing device is needed. After the bottle is fixed, it needs to be rotated and positioned for subsequent testing. At this time, the control panel 32 controls the cylinder 20 to work. The actuating end of the cylinder 20 pushes the slider 18 to slide in the rectangular groove 17. Since the rack 21 and the gear 16 mesh with each other, the sliding of the slider 18 drives the rack 21 to move, thereby driving the bottle to move. Gear 16 rotates, causing rotating shaft 13 to rotate, which in turn causes support plate 14 to rotate. Placement cavity 2, located on the top side of support plate 14, and the bottle inside the cavity also begin to rotate. During the rotation of rotating shaft 13, connecting rod 24 and pressing plate 25 also move together. When pressing plate 25 moves to contact a trigger switch 23 on the outside of support column 22 and presses the trigger switch 23, the trigger switch 23 transmits a signal to control panel 32. After receiving the signal, control panel 32 controls cylinder 20 to stop working. At this time, placement cavity 2 of a bottle to be tested is located directly below pressing plate 28, achieving precise positioning of the bottle and preparing for subsequent accurate pressure resistance testing. After the bottle is positioned, the control panel 32 controls the hydraulic cylinder 27 to start. The working end of the hydraulic cylinder 27 drives the pressing plate 28 to move downward. The rubber pad 29 mounted on the bottom side of the pressing plate 28 first contacts the bottle and begins to apply pressure to the bottle to test its pressure resistance. During the pressing process, the pressure sensor 31 monitors the pressure value of the pressing plate 28 on the bottle in real time. The pressure sensor 31 transmits the monitored pressure signal to the control panel 32. The control panel 32 judges whether the bottle is qualified according to the preset standard. After the pressure test of a bottle is completed, the working end of the hydraulic cylinder 27 extends, the pressing plate 28 moves away from the bottle, and the pressure sensor 31 can no longer detect the pressure value. The pressure sensor 31 transmits this signal to the control panel 32, which controls the telescopic rod 11 to shorten, releasing the bottle from its fixation. At the same time, the control panel 32 controls the cylinder 20 to move, the working end of the cylinder 20 shortens or extends, driving the next placement chamber 2 containing a bottle to move directly below the pressing plate 28, starting the next round of testing. When the gear 16 rotates 360 degrees under the action of the cylinder 20, the working end of the cylinder 20 will shorten, causing the gear 16 to rotate in the opposite direction. The specific models of the pressure sensor 31 and the trigger switch 23 are Honeywell-1750 and Omron-D4GL, respectively.
[0019] Working principle: When testing high-barrier polyethylene bottles, the bottle is first placed on the tray 8. Due to the bottle's own weight and the external force applied during placement, the tray 8 moves downward, causing the sliding block 6 to slide down along the support rod 5 in the groove 4. The tension spring 7 is stretched. As the tray 8 descends, the electrode plate 9 gradually approaches the electrode plate 3 until the two contact. At this time, the circuit formed by the electrode plate 3, electrode plate 9, indicator light 10, and power supply is connected, and the indicator light 10 lights up. At the same time, the signal of the indicator light 10 lighting up is transmitted to the control panel 32 through the signal line. The control panel 32 starts the extension of the telescopic rod 11. The working end of the telescopic rod 11 extends and pushes the clamping plate 12 to clamp and fix the bottle, realizing automated bottle fixing, improving the efficiency of testing, and reducing the time for switching the clamping components. After the bottle is fixed, it needs to be rotated and positioned for subsequent testing. At this time, the control panel 32 controls the cylinder 20 to work. The working end of the cylinder 20 pushes the slider 18 to slide in the rectangular groove 17. Since the rack 21 and the gear 16 mesh with each other, the sliding of the slider 18 drives the rack 21 to move, which in turn drives the gear 16 to rotate. The rotation of the gear 16 causes the rotating shaft 13 to rotate, and the rotating shaft 13 causes the support plate 14 to rotate accordingly. The placement cavity 2 placed on the top side of the support plate 14 and the bottle in the cavity also begin to rotate. During the rotation of the rotating shaft 13, the connecting rod 24 and the pressing plate 25 also move together. When the pressing plate 25 moves to contact a trigger switch 23 on the outside of the support column 22 and presses the trigger switch 23, the trigger switch 23 transmits a signal to the control panel 32. After receiving the signal, the control panel 32 controls the cylinder 20 to stop working. At this time, the placement cavity 2 of the bottle to be tested is located directly below the pressing plate 28, realizing the precise positioning of the bottle and preparing for the subsequent accurate pressure test. After the bottle is positioned, the control panel 32 controls the hydraulic cylinder 27 to start. The working end of the hydraulic cylinder 27 drives the pressing plate 28 to move downward. The rubber pad 29 mounted on the bottom side of the pressing plate 28 first contacts the bottle and begins to apply pressure to the bottle to test its pressure resistance. During the pressing process, the pressure sensor 31 monitors the pressure value of the pressing plate 28 on the bottle in real time. The pressure sensor 31 transmits the monitored pressure signal to the control panel 32. The control panel 32 judges whether the bottle is qualified according to the preset standard. After the pressure test of a bottle is completed, the working end of the hydraulic cylinder 27 extends, the pressing plate 28 moves away from the bottle, and the pressure sensor 31 can no longer detect the pressure value. The pressure sensor 31 transmits this signal to the control panel 32, which controls the telescopic rod 11 to shorten, releasing the bottle from its fixation. At the same time, the control panel 32 controls the cylinder 20 to move, the working end of the cylinder 20 shortens or extends, driving the next placement cavity 2 containing a bottle to move directly below the pressing plate 28, starting the next round of testing. When the gear 16 rotates 360 degrees under the action of the cylinder 20, the working end of the cylinder 20 will shorten, causing the gear 16 to rotate in the opposite direction.
