Technical Field

[0001] This utility model relates to the field of elasticity testing, and in particular to an elasticity testing device for a seal. Background Technology

[0002] For some containers used to hold liquids, elastic seals are used for sealing. The elasticity of the seals must meet the required standards; if the elasticity does not meet the product's requirements, an effective seal cannot be achieved. Therefore, it is necessary to test the elasticity of the seals, but manual testing is obviously inefficient. Utility Model Content

[0003] The purpose of this invention is to address the problems existing in the background technology by proposing an elasticity testing device for sealing components, which can automatically perform elasticity testing on continuously fed sealing components, with high testing efficiency and a high degree of automation.

[0004] The technical solution of this utility model is a sealing element elasticity testing device, including a feeding mechanism and an elasticity testing device. The feeding mechanism includes a housing, a vibrating plate disposed inside the housing, a conveying track with one end connected to the discharge end of the vibrating plate, and a support assembly disposed on the housing for mounting the conveying track. The elasticity testing device includes an elasticity testing mechanism, a cabinet, and a mounting shell, a mounting base, and a central control console disposed on the cabinet. The elasticity testing mechanism includes a turntable rotatably disposed on the mounting shell, a motor disposed on the mounting shell and driving the turntable to rotate, an electric cylinder vertically disposed on the mounting base, and a pressure sensor disposed at the bottom of the electric cylinder. The pressure sensor is communicatively connected to the central control console, and the central control console is controllably connected to the motor and the electric cylinder. The outer circumference of the upper surface of the turntable has multiple uniformly distributed work station slots, which sequentially receive the sealing elements conveyed from the conveying track when rotating.

[0006] Preferably, the turntable is open in the middle, and both the first and second air blowing pipes extend upward from the middle of the turntable. The outer end of the work station slot has a slot, and the first and second fiber optic sensors face the slots of the two work station slots respectively when detecting the seal.

[0007] Preferably, the mounting base is provided with a pressure plate, and both sides of the outer end of the pressure plate have upwardly inclined folded plate portions. When the sealing element is transported from the conveying track to the corresponding work station slot, it is pressed down into the work station slot by the outer end of the pressure plate.

[0015] Example 1: As Figures 1-5 As shown in the figure, the elasticity testing device for a seal proposed in this embodiment includes a feeding mechanism and an elasticity testing device.

[0016] The feeding mechanism includes a housing 1, a vibratory feeder 2 housed inside the housing 1, a conveying track 5 connected at one end to the discharge end of the vibratory feeder 2, and a support assembly mounted on the housing 1 for mounting the conveying track 5. Two sets of the vibratory feeder 2, the conveying track 5, and the support assembly are symmetrically arranged to improve feeding efficiency.

[0017] The vibratory feeder 2 has a spiral feeding channel 201. The upper part of the vibratory feeder 2 is inclined, and the material is fed in a spiral shape through the spiral feeding channel 201 during vibration. The top of the housing 1 has a feeding port 101 to facilitate the addition of the seal to be tested into the vibratory feeder 2 by the worker. When the seal is a cup-shaped seal, a support 3 is provided inside the housing 1. The bottom of the support 3 is provided with a deflector 4 for moving the seal. The lower part of the deflector 4 is bent outward. The deflector 4 is located inside the bottom of the spiral feeding channel 201, with a certain gap. One end of the cup-shaped seal is a small opening, and the other end is a large opening. The diameter of the large opening is larger than the diameter of the small opening. The vibratory feeder 2 needs to convey the seal with the small opening facing upward. By setting the deflector 4, if the seal is to enter the bottom of the spiral feeding channel 201 with the small opening facing upward, it will pass smoothly through the gap area between the deflector 4 and the spiral feeding channel 201. If the seal is to enter the bottom of the spiral feed channel 201 with its wide opening facing upwards, it will be blocked by the deflector 4 when it moves to the interval area. However, the seal will continue to move and be flipped to a narrow opening facing upwards, thus adjusting the distribution of the seals so that all seals ultimately conveyed to the conveying track 5 via the vibratory feeder 2 are in a narrow opening facing upwards distribution. If the seal is not a bowl-shaped structure and the orientation of the seals during feeding can be detected by the elasticity detection device, then the bracket 3 and the deflector 4 are not designed.

[0018] like Figure 2 and Figure 4 As shown, the inner side of the conveying track 5 has a conveying channel that runs through the length direction. The vibrating plate 2 feeds multiple seals into the conveying channel in sequence, and pushes the seals in front by continuing to convey the seals in the rear, and finally discharges the seals in sequence from the end of the conveying track 5.

[0019] like Figure 2 and Figure 3As shown, the support assembly includes a transverse frame 6, a lifting frame 7, bolt 1 8, a mounting platform 9, bolt 2 10, a fixing frame 11, and bolt 3 12. The conveyor track 5 is mounted on the transverse frame 6. The lifting frame 7 has horizontally distributed slotted holes. Bolt 1 8 passes through these slotted holes and is threaded onto the transverse frame 6, allowing for fine-tuning of the transverse frame 6's lateral position by adjusting the position of bolt 1 8 through the slotted holes. The mounting platform 9 is located below the lifting frame 7. Bolt 2 10 is vertically mounted at the bottom of the lifting frame 7 and is threaded with two nuts 1, which are respectively fastened to the upper and lower sides of the top of the mounting platform 9. This allows for adjustment of the height of the lifting frame 7 by adjusting the position of the two nuts 1. Bolt 3 12 is vertically mounted at the bottom of the fixing frame 11 and is threaded with two nuts 2, which are respectively fastened to the upper and lower sides of the bottom of the mounting platform 9. The fixing frame 11 is mounted on the housing 1, allowing for adjustment of the height of the mounting platform 9 by adjusting the position of the two nuts 2. By comprehensively adjusting the bolts and nuts, the feed end of the conveying track 5 can be connected and aligned with the discharge end of the spiral feed channel 201 to accurately receive the sealing parts fed by the vibrating plate 2.

[0020] like Figure 1 , Figure 2 and Figure 4 As shown, the elasticity testing device includes an elasticity testing mechanism, a cabinet 29, and a mounting shell 13, a mounting base 19, and a central control panel 30 mounted on the cabinet 29. Two sets of elasticity testing mechanisms are symmetrically arranged, corresponding to two sets of conveying tracks 5, respectively, to receive and test the conveyed seals, improving testing efficiency. The elasticity testing mechanism includes a turntable 17 rotatably mounted on the mounting shell 13, a motor mounted on the mounting shell 13 and driving the turntable 17 to rotate, an electric cylinder 20 vertically mounted on the mounting base 19, and a pressure sensor 21 located at the bottom of the electric cylinder 20. The outer circumference of the upper surface of the turntable 17 has multiple evenly distributed workstation slots 171, which sequentially receive the seals conveyed from the conveying tracks 5 during rotation. After the sealing element is conveyed from the conveyor track 5 to the initial position slot 171, the intermittent rotation of the turntable 17 transports the sealing element to below the pressure sensor 21. Then, the electric cylinder 20 drives the pressure sensor 21 downwards, pressing it against the sealing element to detect the pressure, i.e., the elasticity of the sealing element. The pressure sensor 21 is communicatively connected to the central control console 30, transmitting the detection results there. The central control console 30 is connected to the motor and the electric cylinder 20, controlling the motor to drive the turntable 17 to rotate intermittently, and also controlling the electric cylinder 20 to drive the pressure sensor 21 downwards to detect the elasticity of the sealing element. After detection, the central control console 30 controls the electric cylinder 20 to drive the pressure sensor 21 upwards.

[0021] like Figure 4As shown, a pressure plate 18 is provided on the mounting base 19. Both sides of the outer end of the pressure plate 18 have upwardly inclined folded portions in the width direction. When the seal is conveyed to the area below the pressure plate 18, the folded portions act as guides. When the seal is conveyed from the conveying track 5 to the corresponding work station slot 171, it is pressed down into the work station slot 171 by the outer end of the pressure plate 18, preventing the rear seal from squeezing the foremost seal off from its initial position in the work station slot 171. However, when the motor drives the turntable 17 to rotate, the turntable 17 can still rotate the seal pressed by the pressure plate 18, thus opening the seal.

[0022] This embodiment can automatically perform elasticity testing on continuously fed seals. During testing, seals are continuously fed via a vibratory feeder 2 and a conveyor track 5, with one seal being transported to the initial workstation slot 171 at a time. As the turntable 17 rotates, the pressure sensor 21 is driven downward by an electric cylinder 20 to intermittently test the elasticity of the seals that have rotated to below the pressure sensor 21, resulting in high testing efficiency and a high degree of automation.

[0023] Example 2: Figures 1-5 As shown, this embodiment proposes a sealing elasticity testing device. Compared to Embodiment 1, in this embodiment, the feeding mechanism further includes a cutting component. The cutting component includes a connecting frame 14 mounted on the mounting housing 13, a cylinder 15 inclinedly mounted on the connecting frame 14, and a baffle 16 mounted on the telescopic end of the cylinder 15. The upper part of the baffle 16 is a vertical plate. The cylinder 15 is controlled by the central control panel 30 to extend and retract. The end of the conveying track 5 away from the vibrating plate 2 has a notch 501. When the baffle 16 tilts upward and moves into the notch 501, it blocks the conveying of subsequent sealing components inside the conveying track 5.

[0024] This embodiment can control the on / off flow of sealing components on the conveyor track 5. When the cylinder 15 retracts, it causes the baffle 16 to tilt upwards, passing through the notch 501. The top of the baffle 16 enters the inner side of the conveyor track 5, blocking the sealing components conveyed by the vibrating plate 2 from the rear, thus stopping the feeding. When feeding needs to continue, the cylinder 15 is extended, causing the baffle 16 to tilt downwards and move away from the conveyor track 5, removing the obstruction and allowing the conveyor track 5 to resume smooth feeding.

[0025] Example 3: Figures 1-5As shown, this embodiment of the sealing elasticity testing device, compared to Embodiment 1, further includes a sorting mechanism. The sorting mechanism includes a guide component 22 and a waste box 28 mounted on the cabinet 29, a guide component 24 inclinedly connected to the top of the waste box 28, fiber optic sensors 23 and 25 mounted on the mounting housing 13, an air blowing pipe 26 that blows qualified sealing components from the workstation groove 171 on one side of the guide component 22 into the inclined guide component 22, an air blowing pipe 27 that blows unqualified sealing components from the workstation groove 171 on one side of the guide component 24 into the guide component 24, and two solenoid valves that control the gas flow in the air blowing pipes 26 and 27 respectively. Both the guide component 22 and the guide component 24 are cylindrical structures with inclined slides. Both the first air blowing pipe 26 and the second air blowing pipe 27 are fixed in the mounting shell 13 and are connected to the external high-pressure air source. The two solenoid valves in the middle are used to control the opening and closing of the passage. When the passage is open, the corresponding air blowing pipe can spray high-pressure gas. The gas pressure is sufficient to blow the seal off the work station groove 171.

[0026] When the pressure sensor 21 transmits the elasticity detection result to the central control unit 30, the central control unit 30 determines whether the elasticity is qualified according to the preset qualified elasticity range. If the detected elasticity is within the qualified elasticity range, the seal is qualified. When the turntable 17 rotates the seal to the side of the guide component 22, the central control unit 30 controls the solenoid valve to open the air blowing pipe 26. The air blowing pipe 26 blows air into the seal, causing the seal to fall into the inclined guide component 22, where the seal will slide down along the inclined direction. If the elasticity of the seal is unqualified, when the turntable 17 rotates the seal to the side of the guide component 24, another solenoid valve opens the air blowing pipe 27. The air blowing pipe 27 blows air into the seal, causing the seal to fall into the inclined guide component 24, where the seal will slide down into the waste box 28 for collection.

[0027] Fiber optic sensor 23 is used to detect whether there is a seal on one side of guide component 22, and fiber optic sensor 25 is used to detect whether there is a seal on one side of guide component 24.

[0028] like Figure 4 As shown, the turntable 17 is open in the middle, and both the first air pipe 26 and the second air pipe 27 extend upward from the middle of the turntable 17. The outer end of the workstation slot 171 has an opening. When the fiber optic sensor 1 23 and the second fiber optic sensor 25 detect the seal, they face the openings of the two workstation slots 171 respectively. If there is a seal at the workstation slot 171, the outer end of the seal can be detected by the fiber optic sensor. The fiber optic sensor detects whether there is a seal at the workstation slot 171 through the corresponding opening.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
