Description

Technical Field

[0001] The present application relates to the field of detection equipment, and in particular to a leak detection device for an ointment packaging tube. Background Art

[0002] At present, in the production and processing of paste products (such as toothpaste, ointment and sauce, etc.), the paste is mainly poured into the corresponding ointment packaging tube by filling and sealing equipment, and the tail end of the tube is heat-sealed, and finally the filled tube is output through the discharge end of the filling and sealing equipment. The existing filling and sealing equipment can output several tubes at a time, and the output is divided into conveying equipment at different output ends.

[0003] In order to ensure the overall quality of the product, it is necessary to test the hoses output by the filling and sealing equipment, so as to timely screen out the unqualified products with leakage. At present, the hose inspection is mainly carried out by manually pressing the hose to observe whether there is any paste leakage at the mold joint and the sealing part of the hose. Some of them are also equipped with specific extrusion equipment to concentrate on squeezing a number of hoses, and then manually identify whether there is leakage by naked eyes.

[0004] Regarding the above-mentioned related technologies, leak detection of hoses generally requires direct or indirect human intervention to complete. On the one hand, the overall leak detection efficiency is low and it is difficult to meet the needs of high-output production lines. On the other hand, manual leak detection depends on the experience and technical level of the operator, and it is easy to miss the detection due to factors such as fatigue. Therefore, there is room for improvement. Summary of the invention

[0005] In order to improve the leak detection efficiency of the hose, the present application provides an ointment packaging hose leak detection device.

[0006] The present application provides an ointment packaging hose leak detection device, which adopts the following technical solution: An ointment packaging tube leak detection device, comprising a conveying line, a feeding mechanism, a squeezing mechanism, a visual mechanism, a rejecting mechanism, and a qualified product conveying mechanism; The conveying line is used for conveying the hose; The feeding mechanism is connected with the discharge end of the filling and sealing equipment, and is used to receive the hose output by the filling and sealing equipment and transmit it to the conveying line; The extrusion mechanism is located downstream of the feeding mechanism, and the extrusion mechanism is used to extrude the hose; The visual mechanism is located downstream of the extrusion mechanism, and is used to obtain an image of the extruded hose and determine whether the hose is leaking; The rejection mechanism is located downstream of the visual mechanism, and is used to reject the leaking hose from the conveying line according to the judgment result of the visual mechanism; The qualified product conveying mechanism is located downstream of the rejecting mechanism, and the qualified product conveying mechanism is used to receive the qualified hose transmitted from the conveying line.

[0007] By adopting the above technical solution, after the hose is output by the filling and sealing equipment, it is first transferred to the conveyor line by the feeding mechanism. When the conveyor line conveys the hose to the extrusion mechanism, the extrusion mechanism squeezes the hose on the conveyor line to expose potential leakage points on the hose. Then, the visual mechanism obtains the image of the extruded hose, and determines whether the hose is leaking through the acquired image analysis. The leaking hose is removed from the conveyor line by the rejection mechanism; the qualified hose is transmitted to the qualified product conveying mechanism via the conveyor line, and is further conveyed to the next processing step by the qualified product conveying mechanism. The automatic detection and rejection of the unloading hose is realized, which reduces the labor intensity and false detection rate compared with the traditional manual detection method, while reducing manual intervention, and effectively improving the leak detection efficiency of the hose.

[0008] Preferably, the conveyor line comprises a loading conveyor belt, the loading conveyor belt is evenly distributed with a plurality of loading parts, the loading parts comprise a plurality of station slots for placing the hoses, and the station slots are connected to the conveying surface corresponding to the loading conveyor belt.

[0009] By adopting the above technical solution and setting the workstation slots, the orderly arrangement and limiting of the hoses during the transportation process are achieved, which is beneficial to limiting the displacement or flipping of the hoses during the transportation process, and facilitates the subsequent extrusion mechanism and the rejection mechanism to better extrude and reject the hoses on the conveyor line, respectively, thereby improving the accuracy and reliability of subsequent extrusion detection.

[0010] Preferably, the feeding mechanism includes several first feeding conveyor belts, and the input ends of the several first feeding conveyor belts are connected one by one with the output ends of the filling and sealing equipment. The output ends of the first feeding conveyor belts are all arranged close to the loading conveyor belts, and the first feeding conveyor belts are used to convey the hose to the work station slot.

[0011] By adopting the above technical scheme, multiple first loading and feeding parts are used to connect several discharge ends of the filling and sealing equipment, which is beneficial to quickly transfer the hoses at different output ends of the filling and sealing equipment to the workstation slots on the loading conveyor belt, realizing multi-channel synchronous feeding, which is beneficial to improving the feeding efficiency of the hoses.

[0012] Preferably, the feeding mechanism also includes a plurality of second feeding conveyor belts, a plurality of the first feeding conveyor belts correspond one-to-one to a plurality of the second feeding conveyor belts, a plurality of the second feeding conveyor belt input ends are connected one-to-one with a plurality of conveying ends of the filling and sealing equipment, an output end of the second feeding conveyor belt is connected with an input end of the corresponding first feeding conveyor belt, and the second feeding conveyor belt is used to convey the hose to the corresponding first feeding conveyor belt.

[0013] By adopting the above technical solution, the output speed of the hoses at different discharge ends of the filling and sealing equipment is prone to inconsistency; by setting the second feeding conveyor belt, the second feeding conveyor belt can be used as a buffer zone. When the output end of the filling and sealing equipment transfers the hose to the second feeding conveyor belt, the conveyance of the second feeding conveyor belt is suspended to temporarily store the hoses from each discharge end. After the hoses at the discharge end of the filling and sealing machine have reached the corresponding second feeding conveyor belt, the second conveyor belt will uniformly transfer the hoses to the corresponding first feeding conveyor belt. This is conducive to ensuring that each station slot of the loading part moved to the feeding mechanism can accurately receive the hose, avoiding the phenomenon of empty slots in the station slots due to delayed delivery of individual discharge end hoses.

[0014] Preferably, the extrusion mechanism includes an extrusion bracket, on which a plurality of extrusion parts are vertically installed corresponding to the plurality of work station slots of the loading part, and the extrusion parts are located above the conveying path of the work station slots; the extrusion bracket is also provided with a lifting drive member for driving the extrusion parts to rise and fall vertically.

[0015] By adopting the above technical solution, after the conveyor line transports several station slots on the loading part to the bottom of several extrusion parts of the extrusion mechanism, the corresponding extrusion parts are driven by the lifting drive member to descend vertically and apply uniform pressure to the hose, thereby realizing batch extrusion of the hose. Compared with the manual extrusion method of the hose, it is beneficial to reduce the errors caused by human factors and improve the overall extrusion efficiency of the hose. At the same time, it is beneficial to uniform force on the hose, so that the paste in the leaking hose can be better squeezed out.

[0016] Preferably, the rejection mechanism includes a pushing part and a collecting box, the pushing part and the collecting box are respectively located on opposite sides of the conveying line, and the pushing part and the collecting box are arranged opposite to each other, the pushing part includes a pushing bracket, the pushing bracket is provided with a pushing block corresponding to the work station slot, the pushing bracket is provided with a pushing driving component corresponding to the pushing block, and the pushing driving component is used to drive the corresponding pushing block to move toward or away from the conveying line.

[0017] By adopting the above technical solution, when the loading conveyor belt transports the work station slot loaded with the leaking hose to the position opposite to the pushing block, the sliding drive component drives the corresponding pushing block to slide into the work station slot, so as to push the leaking hose in the work station slot into the collection box, thereby realizing the automatic removal of the leaking hose and effectively improving the removal efficiency of unqualified hoses.

[0018] Preferably, a guide cover is provided at the end of the conveyor line, the bottom end of the guide cover is located at the bottom of the conveyor line, and when the station slot is located in the guide cover, the top notch of the station slot is arranged close to the inner periphery of the guide cover; The qualified product conveying mechanism is located below the conveying line; the qualified product conveying mechanism includes a receiving conveyor belt; the receiving conveyor belt is located below the bottom end port of the air deflector; the receiving conveyor belt is used to receive and convey the qualified hose that falls out of the work station slot.

[0019] By adopting the above technical scheme, the guide cover is used in conjunction with the loading conveyor belt to limit the situation where the hose falls out of the work station slot during the movement of the work station slot at the end of the loading conveyor belt, which is conducive to the qualified hose in the work station slot being transported to the bottom of the loading conveyor belt. When the work station slot containing the qualified hose moves out of the bottom end port of the guide slot, the qualified hose inside the work station slot automatically falls onto the receiving conveyor belt, thereby realizing the automatic discharge and transfer of the qualified hose.

[0020] Preferably, the receiving conveyor belts are provided in plurality, and the plurality of receiving conveyor belts are arranged in parallel along the conveying direction of the conveying line; The qualified product conveying mechanism further comprises a merging conveyor belt and a blocking member; the conveying surface of the merging conveyor belt is supported with two guide plates, and the distance between the two guide plates gradually decreases from the input end of the merging conveyor belt toward the output end of the merging conveyor belt; the output ends of the receiving conveyor belts are all connected to the input end of the merging conveyor belt; The blocking member is blocked above the receiving conveyor belt close to the air guide cover, and the blocking member is horizontally slidably arranged; After the receiving conveyor belt far away from the deflector receives the qualified hose dropped from the corresponding station slot and conveys it to the merging conveyor belt, the blocking piece is slid to open the receiving conveyor belt close to the deflector.

[0021] By adopting the above technical scheme, multiple receiving conveyor belts can simultaneously receive qualified hoses from different workstation slots, and transport them to the merging conveyor belt, which will then cooperate to transport them to the next process, effectively improving the transfer and transportation efficiency of qualified hoses. Through the setting of the blocking parts, the hoses in adjacent workstation slots can be made to fall into the corresponding receiving conveyor belts front and back, which is conducive to reducing the situation where the hoses in adjacent workstation slots fall into the corresponding receiving conveyor belts at the same time, causing blockage or confusion of subsequent hoses during the transportation process of the merging conveyor belt, and is conducive to the orderly entry of the hoses into the merging conveyor belt.

[0022] Preferably, it further comprises a cleaning mechanism, the cleaning mechanism being located downstream of the qualified product conveying mechanism; and the cleaning mechanism being located below the conveying line; the cleaning mechanism being used to clean the station slot loaded with the leaking hose according to the judgment result of the visual mechanism; The cleaning mechanism comprises a cleaning box, in which a plurality of cleaning parts are arranged corresponding to the plurality of station slots of the loading part, and the cleaning parts comprise a vertically supported cleaning pipe, and the cleaning pipe is connected to a water source and an air source.

[0023] By adopting the above technical solution, after the hose is squeezed by the squeezing mechanism, the paste in the leaking hose is likely to leak out and remain in the loading station slot, causing interference with the subsequent detection of the next batch of hoses. Through the setting of the cleaning mechanism, when several station slots of the loading part are moved above the corresponding cleaning pipe, the corresponding cleaning pipe sprays water and blows air to dry the station slots contaminated by the paste to remove the residual paste on the station slot, ensuring the clean state of the station slot when it is used next time.

[0024] Preferably, the loading conveyor belts are provided with two groups, and the two groups of the loading conveyor belts are arranged in parallel; the number of the loading parts on the loading conveyor belts is three; When one of the loading parts of a group of the loading conveyor belts is located at the feeding mechanism, the other two loading parts of the group of the loading conveyor belts are respectively located at the rejection mechanism and the qualified product conveying mechanism; at the same time, two of the loading parts of another group of the loading conveyor belts are respectively located at the extrusion mechanism and the cleaning mechanism.

[0025] By adopting the above technical solution and utilizing the two loading conveyor belts to cooperate with each other, it is beneficial to adapt to the operating characteristics of different processes, so that processes that require intermittent and rapid movement of the loading part, such as the feeding mechanism, the rejection mechanism, and the qualified product converging mechanism, and processes that require slow and paused movement of the loading part, such as the extrusion mechanism and the cleaning mechanism, can be carried out in parallel, avoiding mutual restraint and waiting during the operation of each mechanism, which is beneficial to reducing the idle time of the equipment and further improving the leak detection efficiency of the equipment.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. The feeding mechanism delivers the hose output by the filling and sealing equipment to the output line, and the hose is transmitted through the conveying line. The hose is first squeezed by the squeezing mechanism, and then the image of the hose after squeezing is obtained by the imaging mechanism to determine whether the hose is leaking. The unqualified leaking hose is removed from the conveying line through the rejection mechanism according to the judgment structure, thereby realizing automatic detection of the hose and automatic rejection of the leaking hose, effectively improving the efficiency of hose leak detection.

[0027] 2. By setting up two loading conveyor belts and using the two loading conveyor belts to cooperate with each other, it is convenient for the loading mechanism, the rejecting mechanism and other processes that require the loading part to move intermittently and quickly to be carried out simultaneously with the extrusion mechanism, the cleaning mechanism and other processes that require the loading part to pause and operate slowly, which is beneficial to reduce the idle time of the equipment and improve the overall leak detection efficiency of the equipment for the hose.

[0028] 3. By setting a blocking piece on the top of the receiving conveyor belt of the qualified product conveying mechanism, the blocking piece is used to limit the hoses at adjacent workstation slots from falling into the corresponding receiving conveyor belts at the same time, so that the adjacent receiving conveyor belts are staggered to receive the hoses falling from the corresponding workstation slots, which is conducive to the orderly flow of the hoses into the merging conveyor belt and limits the squeezing and blockage of subsequent hoses when they flow into the merging conveyor belt.

DETAILED DESCRIPTION

[0044] The following is combined with Figure 1-13 This application is further described in detail.

[0045] The present application embodiment discloses a leak detection device for an ointment packaging hose, referring to Figure 1 , including a frame, on which a conveying line 1, a feeding mechanism 2, an extrusion mechanism 3, a visual mechanism 4, a rejection mechanism 5, a qualified product conveying mechanism 6 and a cleaning mechanism are arranged.

[0046] Reference Figures 2 to 4 The conveyor line 1 is used for conveying hoses. Specifically, the conveyor line 1 includes a frame, which supports two parallel loading conveyor belts 11, and three loading parts 12 are evenly distributed on the loading conveyor belts 11. The loading part 12 includes a plurality of station slots 121, and the station slots 121 are used for placing hoses. The bottom of the station slot 121 is connected to the conveying surface of the corresponding conveyor line 1, and the two ends of the station slot 121 extend to the opposite sides of the two loading conveyor belts 11 respectively.

[0047] Reference Figure 1 and Figure 5 The feeding mechanism 2 is arranged close to the conveyor line 1 and is used to transfer the hose output from the output end of the filling and sealing machine into the station slot 121 located on the conveyor line 1.

[0048] The feeding mechanism 2 includes two first feeding conveyor belts 21 and two second feeding conveyor belts 22. Both the first feeding conveyor belt 21 and the second feeding conveyor belt 22 are used to convey the hose, and the conveying directions of both are perpendicular to the conveying direction of the loading conveyor belt 11.

[0049] Two first feeding conveyor belts 21 are arranged in parallel and the output ends of the two first feeding conveyor belts 21 are arranged close to the conveyor line 1. Two second feeding conveyor belts 22 are arranged in parallel, and the input ends of the two second feeding conveyor belts 22 are respectively connected with the two output ends of the filling and sealing equipment, and are used to receive the hoses transmitted from the discharge end of the filling and sealing equipment; the output ends of the two second feeding and charging conveyor belts 11 are respectively connected with the input ends of the two first feeding conveyor belts. In this embodiment, both the first feeding conveyor belt 21 and the second feeding conveyor belt 22 are composed of two conveyor belts distributed up and down, and a conveying gap for the hose to enter is formed between the two conveyor belts.

[0050] Through the setting of the feeding mechanism 2, when the feeding mechanism 2 is used for subsequent feeding, the loading part 12 is driven by the loading conveyor belt 11 to move to the feeding mechanism 2 area, and the vacant workstation slot 121 is opposite to the output end of the first feeding conveyor belt 21, and the output hose at the discharge end of the filling and sealing equipment is sent to the corresponding workstation slot 121 through the corresponding second feeding conveyor belt 22 and the first feeding conveyor belt 21 to complete the feeding of the hose.

[0051] By setting up two first feeding conveyor belts 21, the loading conveyor belt 11 can move the distance between the two workstation slots 121 at a time, so that the two workstation slots 121 are respectively opposite to the output ends of the two first feeding conveyor belts 21, and then the two first feeding conveyor belts 21 respectively deliver the hoses to the workstation slots 121 opposite thereto, so that the loading of two hoses can be completed at a time, which effectively improves the loading efficiency of the hoses.

[0052] By setting up two second feeding conveyor belts 22, after the hose first transmitted from the discharge end of the filling and sealing equipment is transmitted to the corresponding second feeding conveyor belt 22, the second feeding conveyor belt 22 will pause to convey the hose to the first feeding conveyor belt 21. After the hoses at the two discharge ends of the filling and sealing equipment are conveyed to the second feeding conveyor belt 22, the two second feeding conveyor belts 22 will simultaneously convey the hoses to the corresponding first feeding conveyor belt 21, and the two first feeding conveyor belts 21 will simultaneously convey the hoses to the relative workstation slots 121, so as to realize the simultaneous feeding of the two hoses and reduce the situation where the workstation slots 121 are empty during the feeding process due to the inconsistent time of outputting the hoses from the discharge end of the filling and sealing equipment.

[0053] Reference Figure 1 and Figure 6 The extrusion mechanism 3 is located downstream of the feeding mechanism 2 and is used to extrude the hose located in the station slot 121.

[0054] The extrusion mechanism 3 includes an extrusion bracket 31 supported above the conveyor line 1, and the extrusion bracket 31 is provided with a plurality of extrusion parts 32 corresponding to the plurality of station slots 121 of the loading part 12. The extrusion part 32 is vertically arranged and is located above the conveying path of the station slots 121. The extrusion part 32 includes a pressure rod 321 and a pressure head 322, and the pressure head 322 is connected to the bottom end of the pressure rod 321. The extrusion bracket 31 is provided with a lifting drive member 33 corresponding to the extrusion part 32, and the lifting drive member 33 is used to drive the extrusion part 32 to lift vertically. Specifically, the lifting drive member 33 includes a lifting cylinder vertically installed on the extrusion bracket 31, and the end of the lifting cylinder piston rod is connected to the top of the pressure rod 321 of the corresponding extrusion part 32.

[0055] Subsequently, the loading conveyor belt 11 transports the loading part 12 containing the hose to be tested to the extrusion mechanism 3, and after the several station slots 121 on the loading part 12 are aligned with the several extrusion parts 32 on the extrusion mechanism 3, the lifting drive member 33 drives the corresponding extrusion part 32 to move downward until the pressure head 322 of the extrusion part 32 presses the hose in the relative station slot 121 and maintains it for 2 seconds. Then, the lifting drive member 33 drives the extrusion part 32 away from the hose in the station slot 121, and uses the extrusion part 32 to squeeze the hose in the station slot 121 so that the paste in the leaking hose can overflow from the leaking place.

[0056] Reference Figure 3 and Figure 6 Two support rails 10 are laid on the upper surface of the frame of the conveyor line 1; rollers 122 are rotatably connected to the opposite ends of the station slot 121, and the rotation axis of the roller 122 is perpendicular to the conveying direction of the conveyor line 1. When the loading conveyor belt 11 drives the station slot 121 to move above the conveyor line 1, the rollers 122 at the opposite ends of the station slot 121 respectively abut against the two support rails 10. The cooperation between the rollers 122 at the two ends of the station slot 121 and the two support rails 10 is used to support the station slot 121, which is conducive to limiting the subsequent downward movement of the station slot 121 due to the squeezing of the hose by the squeezing part 32, so that the squeezing part 32 can better squeeze the hose located in the station slot 121.

[0057] Reference Figure 1 and Figure 7 The visual mechanism 4 is located downstream of the extrusion mechanism 3, and is used to obtain the image of the hose after extrusion and determine whether it leaks according to the image of the hose. Specifically, the visual mechanism 4 includes a visual camera 41 and a controller. The visual camera 41 is supported above the conveyor line 1 by a mounting bracket 40, and the visual camera 41 is arranged relative to the conveying path of the station slot 121 of the loading conveyor belt 11. The visual camera 41 is electrically connected to the controller. The visual camera 41 is used to obtain the image of the hose in the station slot 121 and feed it back to the controller. The controller is used to determine whether the hose in the station slot 121 leaks according to the image fed back by the visual camera 41.

[0058] Reference Figure 1 and Figure 8 The rejecting mechanism 5 is located downstream of the visual mechanism 4 and is used to reject the leaking hose from the workstation slot 121 according to the judgment result of the controller of the visual mechanism 4.

[0059] Reference Figure 8 and Fig. 9 The rejecting mechanism 5 includes a pushing part 51 and a collecting box 52; the pushing part 51 and the collecting box 52 are respectively located on the opposite sides of the conveyor line 1 and the pushing part 51 and the collecting box 52 are arranged opposite to each other; the pushing part 51 includes a pushing bracket 511 supported on the side of the conveyor line 1, and two pushing blocks 512 are supported on the side of the conveyor line 1 facing the pushing bracket 511, and the pushing bracket 511 supports two pushing driving members 513 corresponding to the two rejecting blocks, and the pushing driving member 513 is drivingly connected to the corresponding pushing blocks 512, and is used to drive the pushing blocks 512 to move horizontally toward or away from the conveyor line 1. Specifically, the pushing driving member 513 includes a pushing cylinder installed on the pushing bracket 511, and the pushing cylinder piston rod is connected to the corresponding pushing block 512, and the pushing cylinder is electrically connected to the controller.

[0060] When the loading conveyor belt 11 transports the work station slot 121 containing the leaking hose to a position opposite to the pushing block 512, the controller controls the pushing cylinder to drive the pushing block 512 to move toward the work station slot 121 of the loading conveyor belt 11 according to the judgment result, and then uses the pushing block 512 to push the leaking hose in the work station slot 121 from the work station slot 121 to the collection box 52, thereby realizing the automatic removal of the leaking hose.

[0061] Reference Figure 2 and Fig.10 , the end of the conveyor line 1 is sleeved with a deflector 13, and the inner cavity contour of the deflector 13 matches the end contour of the two loading conveyor belts 11. The ends of the two loading conveyor belts 11 are both located in the deflector 13; the bottom end of the deflector 13 extends to the bottom of the conveyor line 1. When the conveying station slot 121 of the loading conveyor belt 11 moves into the deflector 13, the notch of the station slot 121 is set close to the inner cavity wall of the deflector 13; the deflector 13 cooperates with the two loading conveyor belts 11 to limit the loading conveyor belt 11 from driving the station slot 121 to move to the end of the conveyor line 1, and the hose in the station slot 121 slides out of the station slot 121, so that the loading conveyor belt 11 can drive the station slot 121 to drive the loaded hose to move to the bottom of the conveyor line 1.

[0062] Reference Fig.10 and Fig.11The lower part of the guide cover 13 is in a mesh shape on the side opposite to the loading conveyor belt 11, which is beneficial to reduce the paste leaked from the leakage hose in the station slot 121 sticking to the guide cover 13 when the station slot 121 moves to the bottom of the loading conveyor belt 11.

[0063] Reference Fig.10 and Fig.12 The qualified product conveying mechanism 6 is located downstream of the rejection mechanism 5 and below the conveyor line 1, and is used to receive the qualified hoses transmitted by the conveyor belt 61 and transmit them to the next process. The qualified product conveying mechanism 6 includes a merging conveyor belt 62 and two receiving conveyor belts 61, and the conveying directions of the merging conveyor belt 62 and the two receiving conveyor belts 61 are both arranged perpendicular to the conveying direction of the conveyor line 1.

[0064] Two guide plates 63 are provided on the merging conveyor belt 62 . The two guide plates 63 are respectively located on opposite sides of the conveying surface of the merging conveyor belt, and the distance between the two guide plates 63 gradually decreases from the input end of the merging conveyor belt 62 toward the output end of the merging conveyor belt 62 .

[0065] The two receiving conveyor belts 61 are located below the two loading conveyor belts 11 of the conveyor line 1. The two receiving conveyor belts 61 are arranged in parallel and below the bottom port of the air guide cover 13 to receive the hoses that fall after the station slots 121 are moved out of the bottom port of the air guide cover 13. The output ends of the two receiving conveyor belts 61 are connected to the input end of the converging conveyor belt 62.

[0066] The qualified product conveying mechanism 6 also includes a blocking member 64 and a blocking driving member 65. The blocking member 64 blocks the receiving conveyor belt 61 near the air deflector 13. The blocking driving member 65 includes a blocking cylinder installed at the bottom of the air deflector 13. The blocking cylinder piston rod is connected to the blocking member 64, which is used to drive the blocking member 64 to slide in the horizontal direction.

[0067] When the loading conveyor belt 11 drives the two work station slots 121 to move out from the bottom end port of the deflector 13 and move to the top of the two receiving conveyor belts 61, the hose in the work station slot 121 away from the deflector 13 falls onto the receiving conveyor belt 61 away from the deflector 13, and the hose in the work station slot 121 close to the deflector 13 is blocked by the blocking member 64; when the receiving conveyor belt 61 away from the deflector 13 receives the hose falling from the corresponding work station slot 121 and conveys it to the converging conveyor belt 62, the blocking member 64 is driven to slide by the blocking drive member 65 to open the receiving conveyor belt 61 close to the deflector 13, so that the hose in the work station slot 121 opposite to it falls onto the receiving conveyor belt 61 close to the deflector 13. Through the above arrangement, the two receiving conveyor belts 61 are staggered to receive the hoses falling out of the station slot 121, which is beneficial to avoid the situation where the two receiving conveyor belts 61 simultaneously convey the hoses to the merging conveyor belt 62, causing blockage when the merging conveyor belt 62 is conveying the hoses, which is beneficial to the merging conveyor belt 62 to convey the hoses in an orderly manner.

[0068] Reference Fig.13 and Fig.14 The cleaning mechanism 7 is located downstream of the qualified product conveying mechanism 6, and the cleaning mechanism 7 is located below the conveying line 1. The cleaning mechanism 7 is used to clean the workstation slot 121 loaded with the leaking hose according to the judgment result of the visual mechanism 4.

[0069] The cleaning mechanism 7 includes a cleaning box 71, and a notch 711 is provided on the top of the cleaning box 71 for the conveyor line 1 to be embedded. The notch 711 of the cleaning box 71 is sleeved on the bottom of the conveyor line 1. The cleaning box 71 supports a number of cleaning sections 72 corresponding to the several station slots 121 of the loading section 12, and the cleaning section 72 includes two cleaning pipes 721 vertically supported. The cleaning pipe 721 is connected with a water supply pipe 722 and an air supply pipe 723, and the water supply pipe 722 and the air supply pipe 723 are connected to a water source and an air source respectively. The water supply pipe 722 and the air supply pipe 723 are respectively installed with a water supply control switch and an air supply control switch, and the water supply control switch and the air supply control switch are both electrically connected to the controller of the visual mechanism 4.

[0070] When the loading conveyor belt 11 drives the loading part 12 to move into the cleaning box 71 and makes the several station slots 121 of the loading part 12 face the several cleaning parts 72 respectively, the controller first controls the water supply control switch of the corresponding cleaning pipe 721 to connect the cleaning pipe 721 with the water source according to the image judgment result, so as to spray water and flush the station slot 121 loaded with the leaking hose through the cleaning pipe 721, and then controls the air supply control switch to connect the cleaning pipe 721 with the air source, so as to blow the station slot 121 loaded with the leaking hose through the cleaning pipe 721 to clean the station slot 121, and reduce the situation that the image mechanism interferes with the acquisition and judgment of the next batch of hose images due to the adhesion of the leaking hose paste to the station slot 121. A drain port 710 is provided at the bottom of the cleaning box 71 to facilitate the discharge of cleaning waste water.

[0071] When one loading part 12 of a set of feeding conveyor belts 11 is located at the feeding mechanism 2, one of the remaining two loading parts 12 of the set of feeding conveyor belts 11 is located at the visual mechanism 4 and the rejection mechanism 5, and the other is located at the qualified product conveying mechanism 6; at the same time, one loading part 12 of another set of feeding conveyor belts 11 is located at the extrusion mechanism 3, and one of the loading parts 12 is located at the cleaning mechanism 7. Through the above arrangement, the two loading conveyor belts 11 cooperate with each other, which is conducive to the simultaneous and parallel development of the processes that require the intermittent and slow movement of the loading part 12 such as the feeding mechanism 2, the visual mechanism 4 and the qualified product conveying mechanism 6 and the processes that require the slow and paused movement of the loading part 12 such as the extrusion mechanism 3 and the cleaning mechanism 7, thereby reducing the mutual restraint and waiting during the operation of each mechanism, thereby helping to reduce the idle time of the equipment and improve the leak detection efficiency of the equipment.

[0072] The implementation principle of the embodiment of the present application is that when leak detection is performed on the hose, the feeding mechanism 2 conveys the hose discharged from the discharge end of the filling and sealing device to the station slot 121 of the loading conveyor belt 11 corresponding to the loading part 12; When the loading conveyor belt 11 drives the loading part 12 to move to the extrusion mechanism 3, the extrusion mechanism 3 squeezes the hose in the station slot 121 so that the paste in the leaking hose leaks out through the leaking point; When the loading conveyor belt 11 drives the loading part 12 to move to the visual mechanism 4, the visual mechanism 4 obtains the image of the station slot 121 of the loading part 12, and determines whether the hose is leaking based on the obtained image; When the loading conveyor belt 11 drives the loading part 12 to move to the rejecting mechanism 5, the rejecting mechanism 5 rejects the leaking hose from the station slot 121 according to the judgment result of the visual mechanism 4; When the loading conveyor belt 11 drives the loading part 12 to move to the qualified product conveying mechanism 6, the qualified product conveying mechanism 6 receives the qualified hose and conveys it to the subsequent process; When the loading conveyor belt 11 drives the loading portion 12 to move to the cleaning mechanism 7 , the cleaning mechanism 7 cleans the station slot 121 loaded with the leaking hose.

[0073] The present application can realize the leakage detection and rejection processing of the hose, effectively improving the leakage detection efficiency of the hose.

[0074] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
