Description
Technical Field
The invention relates to the technical field of detection, in particular to high-speed leakage detection equipment and method for tail sealing of a cosmetic hose.
Background
The tail sealing hose is one of the packages frequently used on cosmetic cream products. The filling principle is that the product is injected from the tail part of the cylindrical hose, and then the opening is sealed by adopting a heat sealing mode, so that the tail sealing hose mostly has a front original shape and a rear flat structure. The place where this form of packaging is most prone to leakage is the heat seal. When the cosmetic is used, the front part of the tail sealing hose is opened, and the product is extruded from the front part by applying a certain pressure to the hose body. If the sealing is poor, the product can leak from the heat sealing edges, so that the tail sealing hose is required to pass through a pressure explosion experiment before leaving a factory, and only the tail sealing packaging without leakage can enter the market.

Such devices must be left with the hose in place for testing. Because the attitude of the hose is required to be maintained and the pressed position of the hose is required to be determined, a baffle is required to be arranged on the limiting belt, and the explosion-measuring pressure head always moves upwards to be away from a moving path of the baffle to continue conveying after the explosion-measuring pressure head is pressed, so that the working efficiency is reduced, and the control difficulty is high. More than 2s are needed for each pressure measuring position to carry out one test, if the working efficiency is accelerated, the number of the pressure measuring mechanisms can only be increased, but the equipment cost is increased, and the fault risk is increased.
There is therefore a need for an improved device to solve the above problems.

Detailed Description
The present invention will be described in further detail with reference to specific examples.
Examples:
as shown in fig. 1, a cosmetic hose tail-sealing high-speed leak detection apparatus 1 includes a holder 11, a conveying unit 12, a pressing unit 13, a visual detection unit 14, a reject unit 15, a feed line 16, a discharge line 17, a push-in mechanism 18, and a display screen 19.
As shown in fig. 1 and 4, the conveying unit 12 horizontally passes through the upper portion of the bracket 11, and the conveying unit 12 includes a belt conveying line 121 and a hose positioning mechanism, which in this embodiment is a baffle 122 located at both sides of the conveying direction of the belt conveying line 121.
The hose positioning mechanism functions to limit the transport posture of the tail-sealing hose 2 so that the pressed position of the tail-sealing hose 2 when lowered by the pressing unit 13 is at a predetermined position. The hose positioning mechanism may also be a spacer provided on the belt of the belt conveyor line 121, the height of the spacer being not higher than the lowest point of the pressure wheel 135. When the hose positioning mechanism is the baffle 122, the tail sealing hose 2 is prevented from deflecting by utilizing the flat property of the tail sealing edge; when the hose positioning mechanism is a spacer, the deflection of the tail hose 2 is prevented by restricting the positions of both sides of the width of the tail hose 2, and the spacer does not affect the normal passage under the pressing unit 13. If the tail-sealing hose 2 cannot limit deflection, the position of the pressing unit 13 pressed on the tail-sealing hose 2 is uncertain, the reaction force of the position close to the hose orifice is larger, and the reaction force of the position close to the tail-sealing edge is smaller, which is not beneficial to representing the actual state when a user presses the hose body.
As shown in fig. 1, 5 and 6, the conveying direction of the feeding line 16 and the conveying direction of the discharging line 17 are perpendicular to the conveying direction of the belt conveying line 121, the inlet of the belt conveying line 121 and the pushing mechanism 18 are located on opposite sides of the outlet end of the feeding line 16, the discharging direction of the feeding line 16 is provided with a front baffle 161, the inlet of the discharging line 17 is located behind the outlet of the belt conveying line 121, and the discharging line 17 is provided with a rear baffle 171 at a position opposite to the outlet of the belt conveying line 121.
The tail hose 2 passes through the feed line 16 along its length, and then the tail hose 2 is blocked by the baffle 122 to be in a relatively stable posture; the pushing mechanism 18 then pushes the tail hose 2 from its width direction onto the belt conveyor line 121, so that the tail hose 2 can be inspected and rejected, and finally blocked by the back plate 171, and the tail hose 2 finally leaves the leak detection apparatus 1 along its length direction through the discharge line 17. The tailgate 171 here also serves to guide the movement of the good, extending in the conveying direction of the discharge line 17 up to the outlet of the discharge line 17.
As shown in fig. 1 and 2, the pressing unit 13 is located above the conveying unit 12, the pressing unit 13 includes a fixing base 131, a lifting adjusting mechanism 132 disposed on the bracket 11 and adjusting the height position of the fixing base 131, a driving wheel 133, a driven wheel 134 and a pressing wheel 135 rotatably disposed on the fixing base 131, a motor 136 driving the driving wheel 133 to rotate, and a synchronous belt 137 wound around the driving wheel 133, the driven wheel 134 and the pressing wheel 135, axes of the driving wheel 133, the driven wheel 134 and the pressing wheel 135 are parallel, the pressing wheel 135 is in contact with the lowest position of the synchronous belt 137, the pressing wheel 135 is rotatably disposed at the lower portion of the fixing base 131, the axis of the pressing wheel 135 is horizontal and perpendicular to the conveying direction of the conveying unit 12, the lowest position of the pressing wheel 135 forms a detection channel for the tail sealing hose 2 to pass through with the belt conveying line 121, and when the tail sealing hose 2 passes through the detection channel, the pressing wheel 135 applies a downward pressing force to the middle part of the tail sealing hose 2.
The design key point of the invention is as follows: the tail hose 2 completes the explosion-pressing operation in the dynamic process of passing through the detection channel. Therefore, the tail sealing hose 2 does not need to stay first and then be subjected to pressure explosion, but sequentially passes through the detection channel in uniform speed conveying, so that the detection efficiency is improved. Because the detection channel is a position with limited height, the tail sealing hose 2 is naturally subjected to pressure explosion force when being extruded through the detection channel, if the tail sealing is intact after pressure explosion, the cream can not be extruded out of the tail sealing edge, and otherwise, the cream can leak out of the tail sealing edge. For the tail sealing hose 2 with different sizes, even if the requirements of the pressure explosion force are the same, the required height of the detection channel can be different, so when the size of the tail sealing hose 2 is changed, the height of the fixing base 131 relative to the connecting bracket 11 is also required to be adjusted through the lifting adjusting mechanism 132, and the equipment is more flexible to use. If the pressing wheel 135 does not rotate, the upper part of the tail sealing hose 2 can be blocked in front of the pressing wheel 135 and cannot normally pass through the detection channel, so that the detection cannot be normally completed. To avoid this situation, the pinch roller 135 needs to be rotated by the drive assembly and transported in conjunction with the belt conveyor line 121. The pressure applied by the pressure wheel 135 is continuously varied during the passage of the hose 2 and has a maximum value, which is a control variable in the leak test by adjusting the height of the test channel by the elevation adjustment mechanism 132. The greater the height of the detection channel, the smaller this maximum value, and conversely the greater the maximum value, with the assurance that the timing belt 137 will contact the outer wall of the tail hose 2.
As shown in fig. 3, the belt body of the synchronous belt 137 wound between the driving wheel 133 and the pressing wheel 135 and the belt body of the synchronous belt 137 wound between the driven wheel 134 and the pressing wheel 135 are both disposed at an inclined angle to form a guide inlet for the tail sealing hose 2 to enter the detection channel.
In order to enhance the conveying effect, the driving assembly includes a driving wheel 133, a driven wheel 134, a motor 136 and a synchronous belt 137, the lowermost end of the pressing wheel 135 is lower than the lowermost ends of the driving wheel 133 and the driven wheel 134, and the synchronous belt 137 may exhibit a diagonal state at both front and rear sides of the pressing wheel 135. The timing belt 137 wound around the driving pulley 133, the driven pulley 134 and the pressing pulley 135 is in a tight state, and the timing belt 137 is operated at the same linear speed as the belt conveyor line 121 by the driving of the motor 136. Here, the pressing wheel 135 is a pressing force indirectly applied to the tail hose 2 by the timing belt 137. Then the upper portion of the tail sealing hose 2 will contact the synchronous belt 137 before passing through the detection channel, and the synchronous belt 137 will generate a downward pressure and a friction force on the tail sealing hose 2, so that the upper and lower sides of the tail sealing hose 2 will be commonly subjected to a forward conveying friction force when passing through the detection channel, so that the tail sealing hose 2 is extruded through the detection channel, and the tail sealing hose 2 is prevented from being blocked in front of the detection channel, so that the detection cannot be completed.
As shown in fig. 1 and 2, two guide rods 111 are erected on the bracket 11, and the fixing base 131 is vertically penetrated by the two guide rods 111.
When the lifting and lowering adjusting mechanism 132 adjusts the pressing unit 13 to lift, the two guide rods 111 can prevent the pressing unit 13 from rotating in the horizontal plane, so that each tail sealing hose 2 can be pressed at the same position when passing through the detection channel, and the detection accuracy is ensured. The guide rod 111 may be replaced by other guide mechanisms such as a slider rail assembly, a track pulley assembly, etc.
As shown in fig. 2 and 3, the pressing wheel 135 is rotatably coupled to the lower portion of the fixing base 131 by a pin sensor 138.
The principle of the pin shaft sensor 138 is that the middle portion 1381 is connected with the pressing wheel 135 through a bearing, the two side portions 1382 are connected with the fixing base 131, a plurality of connecting portions 1383 are arranged between the middle portion 1381 and the side portions 1382, and the stress deformation of the connecting portions 1383 is used for representing the pressure when the pin shaft sensor is pressed. The pin sensor 138 serves here to determine the maximum pressure at which the pinch roller 135 presses against the hose 2, which is a determined value after the adjustment of the lifting and lowering mechanism 132 has been completed. Because this maximum pressure is sensitive to changes in the height of the pressure wheel 135, direct sensing of the pressure allows for better control of this experimental parameter of the pressure burst.
As shown in fig. 1, the visual inspection unit 14 is located at the outlet side of the pressing unit 13, and the visual inspection unit 14 photographs the tail hose 2 passing through the inspection passage downward.
After the pressing unit 13 and the conveying unit 12 apply a certain pressure to the tail sealing hose 2, the tail sealing of the defective product can be broken, and then leakage occurs. The visual inspection unit 4 is used here to directly take a picture of the situation after the tail-sealing hose 2 has been pressed, and it can be determined that the package is not acceptable once the presence of a leak in the tail of the tail-sealing hose 2 has been detected.
As shown in fig. 1, the display screen 19 is disposed at the highest position of the leak detection device 1, and the display screen 19 is used as a display component of the device processing unit, so that the pressure curve measured by the pin sensor 138 and the product image shot by the visual detection unit 4 can be visually displayed, so that the device operator can know the real-time running condition of the leak detection device 1.
As shown in fig. 1 and 4, the outlet side of the visual inspection unit 14 is provided with a rejecting unit 15, the rejecting unit 15 includes a rejecting mechanism 151 and a waste collection box 152, and the rejecting mechanism 151 and the waste collection box 152 are disposed on two sides of the conveying direction of the belt conveying line 121.
When the pin sensor 138 detects the pressure signal, the control system of the leak detection apparatus 1 will know that the tail sealing hose 2 passes, and then the visual detection unit 14 completes the detection and determines whether the tail sealing hose 2 is defective. If the passing tail hose 2 is identified as defective, then the reject mechanism 151 will rapidly reject the defective into the reject box 152 as it continues to pass in front of the reject mechanism 151, and then retract rapidly so that the defective will not enter the discharge line 17 nor will the subsequent defective be hindered from moving onto the discharge line 17. When a defective product is found, the leak detection device 1 can be temporarily stopped, and a worker waits for wiping off the cream leaked onto the belt of the belt conveyor line 121, so as to avoid misjudgment of leakage caused by the cream after the belt conveyor line 121 circularly conveys for one circle.
As shown in fig. 1 and 4, the belt conveyor line 121 is provided at its end with a transition plate 123, and the side of the transition plate 123 closer to the conveyor unit 12 is higher than the side closer to the discharge line 17.
The inclined state of the transition plate 123 can help the tail hose 2 leaving the belt conveyor line 121 slide down onto the discharge line 17.
The working flow of the leak detection device 1 is as follows: firstly, placing a standard tail sealing hose 2 into a detection channel, measuring the pressure in real time by a pin shaft sensor 138, and adjusting the relative height of a fixed seat 131 and a belt conveying line 121 by a lifting adjusting mechanism 132 to enable the highest value of the pressure to reach the set pressure explosion force, thus completing debugging; starting the leak detection device 1, enabling the tail sealing hose 2 to be detected to longitudinally enter from an inlet of the feed line 16, and after the tail sealing hose 2 is blocked by the front baffle 161, transversely pushing the tail sealing hose onto the belt conveying line 121 by the pushing mechanism 18, enabling the tail sealing hose 2 to pass through a detection channel under the condition that the belt conveying line 121 and the synchronous belt 137 keep synchronous running at equal linear speed, and performing a pressure explosion test, wherein if the sealing of the tail sealing hose 2 is free of problems, the package is kept complete, no cream leaks, and otherwise, the cream can leak from the tail; after the pin shaft sensor 138 receives the set interval time of the pressure signal (obtained by dividing the horizontal distance from the lowest point of the pressure applying wheel 135 to the optical axis of the visual detection unit 14 by the linear speed of the belt conveying line 121), the visual detection unit 14 will take a photograph of the tail sealing position of the tail sealing hose 2, then judge and know whether the tail sealing hose 2 leaks, and then the rejecting mechanism 151 pushes the defective products moving to the front into the waste collecting box 152 rapidly and retracts rapidly so as to avoid blocking the passing of the defective products; the good slides from the transition plate 123 to the discharge line 17 and is blocked by the back plate 171, the discharge line 17 moves the good out of the leak detection apparatus 1.
The belt conveyor line 121 of the leak detection device 1 keeps continuous operation in the leak detection process, stops are not needed, the control difficulty is low, the higher working efficiency is ensured, and compared with the existing device, the cost is low, and the fault risk is lower.
What has been described above is merely some embodiments of the present invention. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit of the invention.
