Description

Technical Field

[0001] This utility model relates to the field of sorting technology, and in particular to a multi-channel hose sealing leakage detection device. Background Technology

[0002] Sealed tubes are a common packaging material for cosmetic creams and lotions. The filling principle involves injecting the product into the tube from the tail end, then sealing the opening with heat. Therefore, sealed tubes typically have a rounded front and a flattened rear. The most vulnerable point for leakage in this type of packaging is the heat-sealed edge. When using cosmetics, the front of the sealed tube is opened, and pressure is applied to force the product out. If the seal is inadequate, the product will leak from the heat-sealed edge. Therefore, sealed tubes undergo a burst test before leaving the factory; only leak-proof packaging is allowed to enter the market.

[0003] Chinese patent CN218330481U discloses a hose leak detection device. In this device, a conveyor simultaneously pressure tests multiple hoses using several sets of pressure testing mechanisms, thereby accelerating the overall testing efficiency. During the testing process, the pressure testing mechanisms can maintain pressure and accurately obtain the test results. However, this device uses the same conveyor to transport all hoses. If a problem is found in the sealing of a hose, it is still necessary to wait for the other hoses to finish pressurizing before it can be dealt with, resulting in a waste of testing time.

[0004] Chinese patent CN117181640A discloses a high-speed leak detection device for cosmetic tube sealing. This device uses a pin-shaft sensor to sense the change in stress deformation of the tube as it rapidly passes under a pressure roller, thereby determining whether the tube sealing is leaking. However, some cosmetic manufacturers require a pressure holding period of several seconds for sealing detection, and the rapid detection method of this device cannot guarantee that the sealing quality will meet the standards under pressure holding conditions.

[0005] Therefore, it is necessary to design a new device that can further improve detection efficiency while ensuring the pressure holding time. Utility Model Content

[0006] The main purpose of this invention is to provide a multi-channel hose end-leaking detection device that can ensure the efficiency of batch detection of hose end-leaking by using multi-channel independent detection, while meeting the pressure holding time requirements and improving the production capacity of the hose production line.

[0007] This utility model achieves the above-mentioned objective through the following technical solution: a multi-channel hose sealing leakage detection device, comprising a feeding conveyor line, a sealing detection unit, and a discharging conveyor line arranged sequentially along a first horizontal direction. Both the feeding conveyor line and the discharging conveyor line convey hoses along the first horizontal direction. A distribution unit is provided above the feeding conveyor line. The sealing detection unit includes multiple sealing detection components arranged side by side along a second horizontal direction, which is perpendicular to the first horizontal direction. The distribution unit includes a bracket, a branch servo motor, and a pair of branch track plates. The bracket spans above the feeding conveyor line. The lower part of the branch track plate is close to the upper part of the feeding conveyor line. The two branch track plates are parallel to each other and form a branch channel between them. The branch servo motor is fixed in the middle of the bracket and drives the two branch track plates to reciprocate around a vertical axis. Each branch track plate has a branch guide plate at its inlet. The two branch guide plates form a channel structure that is wider at the front and narrower at the back at the inlet of the branch channel. The second horizontal direction is perpendicular to the first horizontal direction.

[0008] Specifically, the sealing detection assembly includes a stepping track conveyor line, a cylinder bracket, a detection cylinder, a detection block, and a detection sensor. The stepping track conveyor line conveys a flexible hose along a first horizontal direction. The cylinder bracket spans above the stepping track conveyor line. The detection cylinder is connected to the cylinder bracket and drives the detection block to move up and down above the stepping track conveyor line. The detection sensor is located above the stepping track conveyor line.

[0009] Furthermore, the sealing detection unit also includes a blocking cylinder and a blocking block, wherein the blocking cylinder drives the blocking block to block the material between the stepping track conveyor line and the discharge conveyor line.

[0010] Furthermore, the detection cylinder and the blocking cylinder are arranged back-to-back on the cylinder bracket, and the blocking cylinder is located on the outlet side of the detection cylinder.

[0011] Specifically, the distribution unit further includes a gate assembly located at the outlet of the branch channel. The gate assembly includes a gate cylinder, a gate plate, and a grating. The gate cylinder is connected to one of its branch track plates and horizontally drives the gate plate to extend into the branch channel. The grating is located on the outlet side of the gate plate to sense whether the hose leaves the branch channel.

[0012] Furthermore, the gate cylinder is located above the branch channel, and the gate plate is inserted into one of its branch track plates from the side.

[0013] Furthermore, the gate assembly also includes a positioning sensor located above the inlet side of the gate plate and sensing the downward-facing flexible hose.

[0014] Furthermore, the positioning sensor is fixed to one of its branch track plates via a vertical adjustment plate and a horizontal adjustment plate. The vertical adjustment plate has a vertical elongated hole, and the horizontal adjustment plate has a horizontal elongated hole. The vertical adjustment plate is fixed to the branch track plate, and the horizontal adjustment plate is adjustablely fixed to the vertical adjustment plate by two screws passing through the vertical elongated hole. The positioning sensor is adjustablely fixed to the horizontal adjustment plate by two screws passing through the horizontal elongated hole.

[0015] Furthermore, two material guide baffles are provided on both sides of the inlet of the stepping track conveyor line, forming a channel that is wider at the front and narrower at the back.

[0016] Furthermore, two material-gathering baffles are provided above the discharge conveyor line, forming a channel structure with a wide inlet and a narrow outlet; a column is provided on each side of the discharge conveyor line, and two connecting rods are provided on the outer side of each material-gathering baffle. The distance between the two connecting rods is adjustable and fixed to the material-gathering baffle. An adjustable connector is provided on each column with adjustable height, and the connecting rod passes through and is fixed to the adjustable connector in the horizontal direction.

[0017] The beneficial effects of this utility model's technical solution are:

[0018] When the feeding conveyor line transports the hoses, they come into contact with the branch guide plate, and the hoses are guided into the space between two branch guide plates, allowing each hose to pass through the channel between the branch guide plates one by one. The branch servo motor adjusts the outlet direction of the branch guide plate channel by reciprocating the oscillation, ensuring that the hoses are fed into the corresponding stepper rail conveyor line. This invention can ensure the efficiency of batch detection of hose sealing leakage through multi-channel independent detection, while also meeting the pressure holding time requirements, thereby increasing the production capacity of the hose production line.

[0034] The present invention will be further described in detail below with reference to specific embodiments.

[0035] Example 1:

[0036] like Figure 1 and Figure 2 As shown, the present invention provides a multi-channel hose sealing leakage detection device 100, which includes a feeding conveyor line 11a, a sealing detection unit 12 and a discharging conveyor line 11b arranged sequentially along a first horizontal direction. Both the feeding conveyor line 11a and the discharging conveyor line 11b convey hoses 200 along the first horizontal direction. A distribution unit 13 is provided above the feeding conveyor line 11a.

[0037] Both the infeed conveyor line 11a and the discharge conveyor line 11b are used for directional conveying of the hoses 200, and belt conveyors with a width greater than five times the width of the hoses 200 are suitable. The sealing detection unit 12 is used to perform independent burst testing on multiple hoses 200. In this embodiment, the sealing detection unit 12 can test four hoses 200 at a time, but in actual applications, the number can be increased or decreased according to the rhythm of the preceding and following processes. The distribution unit 13 distributes the hoses 200 into the various channels of the sealing detection unit 12. The material gathering baffle 14 gathers the tested hoses 200 to the middle of the discharge conveyor line 11b during conveying.

[0038] like Figure 3 and Figure 4 As shown, the sealing detection unit 12 includes multiple sealing detection components 12a arranged side by side along a second horizontal direction, which is perpendicular to the first horizontal direction. Each sealing detection component 12a includes a stepping track conveyor line 121, a cylinder bracket 122, a detection cylinder 123, a detection block 124, and a detection sensor 127. The stepping track conveyor line 121 conveys a flexible hose 200 along the first horizontal direction. The cylinder bracket 122 spans above the stepping track conveyor line 121. The detection cylinder 123 is connected to the cylinder bracket 122 and drives the detection block 124 to move up and down above the stepping track conveyor line 121. The detection sensor 127 is located above the stepping track conveyor line 121, and a pressure sensor is installed inside the detection block 124.

[0039] Multiple end-capping detection components 12a form independent hose detection channels, and the hoses 200 are independently conveyed in different stepping track conveyor lines 121. The hoses 200 to be detected are distributed into each stepping track conveyor line 121 via the distribution unit 13. Then, each hose 200 moves towards the discharge conveyor line 11b under the action of the stepping track conveyor line 121 until it reaches directly below the detection block 124. The detection cylinder 123 lowers the detection block 124 to a set height, thereby pressing the hose 200 vertically and vertically against the detection block 124 and the stepping track conveyor line 121 to the required pressure and holding the pressure for 3 seconds. The detection sensor 127 is used to detect whether the hose 200 has passed a specific position on the stepping track conveyor line 121. If the detection sensor 127 is only used to detect the hose 200 entering the stepper conveyor line 121, then the position of the detection sensor 127 is suitable to be set near the entrance of the stepper conveyor line 121, and the detection is performed vertically. If the detection sensor 127 is used to detect whether the hose 200 has reached the detection position, then the position of the detection sensor 127 is suitable to be set below and behind the detection pressure block 124, and the detection is performed horizontally. If there is no leakage at the sealing end, the maximum pressure signal received by the pressure sensor will remain stable above a set value; otherwise, the pressure received by the pressure sensor will suddenly drop below a certain set value.

[0040] like Figure 5 As shown, the distribution unit 13 includes a support 131, a branch servo motor 132, and a pair of branch track plates 133. The support 131 spans above the feeding conveyor line 11a, and the lower part of the branch track plates 133 is close to the upper part of the feeding conveyor line 11a. The two branch track plates 133 are parallel to each other and form a branch channel between them. The branch servo motor 132 is fixed in the middle of the support 131 and drives the two branch track plates 133 to reciprocate around a vertical axis. Each branch track plate 133 has a branch guide plate 1331 at its inlet, and the two branch guide plates 1331 form a channel structure that is wider at the front and narrower at the back at the inlet of the branch channel.

[0041] The distribution unit 13 is used to selectively distribute the hoses 200 one by one to each sealing detection component 12a. Because the distance between the two branch track plates 133 is generally only 1-2 mm larger than the width of the hoses 200, the hoses 200 can only be arranged in a row in the branch channel and cannot move side by side. The branch feed plate 1331 allows hoses 200 within a certain width range on the feed conveyor line 11a to converge between the two branch track plates 133, thereby allowing the hoses 200 to move backward end to end in the branch channel. The power for the hoses 200 to move into and out of the branch channel comes from the feed conveyor line 11a. There is only a very small gap between the lower part of the branch track plate 133 and the upper part of the feed conveyor line 11a, which is much smaller than the height of the hoses 200 when they are lying horizontally, so the hoses 200 will not leak outside the branch track plate 133 when moving along the first horizontal direction. When the feed conveyor 11a conveys the hose 200, it contacts the branch guide plate 1331, and the hose 200 is guided into the space between the two branch guide plates 133, allowing the hose 200 to pass through the channel between the branch guide plates 133 one by one. However, because the sealing detection components 12a are arranged horizontally side by side at the outlet of the feed conveyor 11a, the branch servo motor 132 needs to adjust the outlet direction of the channel of the branch guide plate 133 by making the branch guide plate 133 swing back and forth, so that the hose 200 can be fed into the corresponding stepper rail conveyor 121. If a sealing detection component 12a finds a problem with the sealing of the hose 200, the sealing detection component 12a will stop working, but the distribution unit 13 will give priority to distributing the hose 200 to other sealing detection components 12a, so the overall detection efficiency will not be affected by a stop in one place. This invention can ensure the efficiency of batch detection of hose end leakage through multi-channel independent detection, while meeting the pressure holding time requirements and improving the production capacity of the hose 200 production line.

[0042] Example 2:

[0043] like Figure 3 and Figure 4As shown, the difference from Embodiment 1 is that the sealing detection unit 12 further includes a blocking cylinder 125 and a blocking block 126. The blocking cylinder 125 drives the blocking block 126 to block the stepping track conveyor line 121 and the discharge conveyor line 11b. The detection cylinder 123 and the blocking cylinder 125 are arranged back-to-back on the cylinder bracket 122, and the blocking cylinder 125 is located on the outlet side of the detection cylinder 123.

[0044] The blocking block 126 is used to stop the hose 200. Because the sealing detection assembly 12a needs to be installed side by side, the width of the stepping track conveyor line 121 is relatively limited. Therefore, the blocking cylinder 125 can only be installed above or below the stepping track conveyor line 121. Since the cylinder bracket 122 has already been installed, the blocking cylinder 125 can also be installed on the cylinder bracket 122. The length of the hose 200 is generally on the order of decimeters, so the distance between the detection pressure block 124 and the blocking block 126 will not be large. It is better to install the detection cylinder 123 and the blocking cylinder 125 back to back. In this embodiment, the detection sensor 127 is used to predict that the hose 200 is about to reach the detection position (i.e., directly below the detection pressure block 124). At this time, it is necessary to ensure that the blocking block 126 blocks the outlet of the stepping track conveyor line 121, so that the hose 200 can temporarily stop directly below the detection pressure block 124. Therefore, the detection sensor 127 does not need to accurately detect the stopping position of the hose 200, which is suitable for setting on the stepping track conveyor line 121. After the detection is completed, the blocking cylinder 125 drives the blocking block 126 away from the outlet of the stepping track conveyor line 121, thereby moving the detected hose 200 out of the stepping track conveyor line 121 and then onto the discharge conveyor line 11b.

[0045] Example 3:

[0046] like Figure 5 and Figure 6 As shown, the difference from Embodiment 1 is that the distribution unit 13 further includes a gate assembly 134. The gate assembly 134 is located at the outlet of the branch channel. The gate assembly 134 includes a gate cylinder 1341, a gate plate 1342, a grating 1343, and a positioning sensor 1344. The gate cylinder 1341 is connected to one of its branch track plates 133 and horizontally drives the gate plate 1342 to extend into the branch channel. The gate cylinder 1341 is located above the branch channel, and the gate plate 1342 is inserted into one of its branch track plates 133 from the side. The grating 1343 is located on the outlet side of the gate plate 1342 to sense whether the hose 200 has left the branch channel. The positioning sensor 1344 is located above the inlet side of the gate plate 1342 and senses the hose 200 downwards.

[0047] All components in the gate assembly 134 are movable along with the branch track plate 133. To prevent the hose 200 from failing to smoothly enter the stepper track conveyor line 121 during branching, the gate assembly 134 temporarily blocks the hose 200 at the outlet of the branch channel. When the branch channel has not swung to the position aligned with the inlet of the stepper track conveyor line 121, the gate plate 1342 blocks the outlet of the branch channel, and the positioning sensor 1344 confirms whether a hose 200 has reached the inlet side of the gate plate 1342. When the branch channel is aligned with the inlet of a stepper track conveyor line 121, the gate cylinder 1341 drives the gate plate 1342 to retract to one side of the branch channel, at which point the hose 200 can leave the branch channel and be detected by the grating 1343. When the grating 1343 no longer detects the hose 200, the gate plate 1342 resets, thus ensuring that only one hose 200 leaves the branch channel at a time. The gate cylinder 1341 is located above the branch pipe channel, which saves width space and also reduces the loosening of the gate assembly 134 structure caused by swinging. When the gate plate 1342 is subjected to the contact force of the hose 200, the branch pipe track plate 133 through which it passes can prevent it from moving along the branch pipe channel, which can also reduce the deformation of the cylinder shaft.

[0048] like Figure 6 As shown, the positioning sensor 1344 is fixed to one of its branch track plates 133 via a vertical adjustment plate 1345 and a horizontal adjustment plate 1346. The vertical adjustment plate 1345 has a vertical elongated hole 13451, and the horizontal adjustment plate 1346 has a horizontal elongated hole 13461. The vertical adjustment plate 1345 is fixed to the branch track plate 133, and the horizontal adjustment plate 1346 is adjustablely fixed to the vertical adjustment plate 1345 via two screws (not labeled) passing through the vertical elongated hole 13451. The positioning sensor 1344 is adjustablely fixed to the horizontal adjustment plate 1346 via two screws (not exposed) passing through the horizontal elongated hole 13461.

[0049] The operating principle of the positioning sensor 1344 is as follows: the front part of the hose 200 first passes through the detection area of ​​the positioning sensor 1344, during which time the feed conveyor line 11a continues to run. Once the rear part of the hose 200 leaves the detection area, the feed conveyor line 11a must stop running. Different hoses 200 have different lengths, so the position of the positioning sensor 1344 must be adjusted accordingly. Depending on the size of the hose 200, the positioning sensor 1344 can be adjusted in both horizontal and vertical directions relative to the branch pipe track plate 133, thereby ensuring accurate identification of the hose 200's position.

[0050] Example 4:

[0051] like Figure 2 and Figure 3As shown, the difference from Embodiment 1 is that: two material guide baffles 1211 are provided on both sides of the inlet of the stepping track conveyor line 121, and the two material guide baffles 1211 form a channel with a wide inlet and a narrow outlet.

[0052] The feed baffle 1211 reduces the difficulty for the hose 200 to enter the stepping track conveyor line 121, avoiding the risk of the hose 200 getting stuck in the stepping track conveyor line 121. Combined with the gate assembly 134 of Embodiment 3, this risk can be reduced to zero. As shown in the figure, because the feed baffle 1211 of the outermost stepping track conveyor line 121 is closer to the edge of the feed conveyor line 11a, some hoses 200 may move directly into the stepping track conveyor line 121 without passing through the distribution unit 13. Therefore, the feed baffle 1211 here is generally longer than the other inner feed baffles.

[0053] Example 5:

[0054] like Figure 1 , Figure 2 and Figure 7 As shown, two material-gathering baffles 14 are provided above the discharge conveyor line 11b, and the two material-gathering baffles 14 form a channel structure with a wide inlet and a narrow outlet.

[0055] In this equipment, in order to achieve multi-channel parallel detection, the hose 200 is intentionally distributed throughout the width of the channel. Before entering the next process, the hose 200 may need to be gathered together to prevent it from falling off due to being too close to the side of the discharge conveyor line 11b.

[0056] like Figure 7 As shown, each side of the discharge conveyor line 11b is provided with a column 15. Each material gathering baffle 14 has two connecting rods 141 on its outer side. The distance between the two connecting rods 141 is adjustable and fixed on the material gathering baffle 14. Each column 15 is provided with an adjustable connector 151 with adjustable height. The connecting rod 141 passes through and is fixed on the adjustable connector 151 in the horizontal direction.

[0057] Because the hose 200 varies in size, the gap between the two material-gathering baffles 14 at the outlet needs to be adjusted appropriately to ensure that the hose 200's posture after leaving the discharge conveyor line 11b meets packaging requirements. The adjustable connector 151 allows for vertical height adjustment of the material-gathering baffle 14 on the column 15, as well as vertical axis rotational freedom. The distance between the two connecting rods 141 must also adapt to changes in angle.

[0058] The working process of the multi-channel hose sealing leakage detection equipment 100 is as follows:

[0059] Multiple hoses 200 move from the manufacturing station to the feed conveyor line 11a in a disordered state. The feed conveyor line 11a moves the hoses 200 along the first horizontal direction. The hoses 200 near the two sides of the feed conveyor line 11a will flow naturally into the outermost sealing detection component 12a. The hoses 200 located in the middle of the feed conveyor line 11a will be blocked by the branch guide plate 1331 and converge into the branch channel. Under the conveying action of the feed conveyor line 11a, they will be arranged in a row until the foremost hose 200 is blocked by the gate plate 1342.

[0060] While keeping the gate plate 1342 stationary, the branch servo motor 132 will rotate the branch track plate 133, thereby aligning the outlet of the branch channel with a stepper track conveyor line 121. When the positioning sensor 1344 confirms that there is a hose 200 on the gate plate 1342, the gate plate 1342 opens. After the hose 200 passes between the gratings 1343, the gate plate 1342 closes. Then, before switching the outlet of the branch channel to another stepper track conveyor line 121, as described above, another hose 200 is sent into the second stepper track conveyor line 121.

[0061] The hose 200 that arrives naturally at the stepper track conveyor line 121 or the hose 200 that passes through the branch channel enters a sealing detection component 12a. At this time, the detection sensor 127 detects the entry of the hose 200, and the blocking block 126 first falls into the track conveyor line 121, so that the hose 200 stops below the detection pressure block 124. The detection cylinder 123 drives the detection pressure block 124 to descend, thereby pressing the hose 200 and holding the pressure for 3 seconds. Whether the sealing is qualified is determined according to whether the pressure can be maintained at the set value. Once an unqualified hose 200 is found, the corresponding sealing detection component 12a stops working, and the distribution unit 13 will not deliver a new hose 200 to the sealing detection component 12a. The detection efficiency of other sealing detection components 12a is not affected. After the unqualified hose 200 is cleared, the sealing detection component 12a continues to work.

[0062] After confirming that the end of the hose 200 is sealed without any problems, the blocking block 126 rises, and the hose 200 passes through and is transferred to the discharge conveyor line 11b. When the detection sensor 127 detects the arrival of a new hose 200, the blocking block 126 falls again, thus ensuring that the hoses 200 pass through the detection positions one by one.

[0063] As the discharge conveyor line 11b continues to convey the hose 200, the two material gathering baffles 14 cause the hose 200 to converge at the middle of the discharge conveyor line 11b until the hose 200 is delivered to the packaging station.

[0064] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
