Description

Technical Field

[0001] This application relates to the field of leak detection equipment, and more particularly to a continuous hose extrusion leak detection device. Background Technology

[0002] In the food, pharmaceutical, and daily chemical industries, paste-like products are typically packaged in tubes. In related technologies, the packaging process usually involves a filling machine first filling the tube with the paste, followed by a sealing machine sealing the end of the tube to complete the packaging.

[0003] During the process of sealing the end of a hose, it is inevitable that the end of the hose may not be properly sealed. Therefore, after the hose is sealed, it is usually necessary to inspect the sealed hose in time to remove any hoses with poor sealing at the end.

[0004] Currently, hose inspection is carried out by manual sampling. Individual hose samples are manually extracted and squeezed by hand, and then the hose end is visually inspected to see if there is any leakage.

[0005] The above inspection method has two drawbacks. First, it requires manual squeezing of the hose, which is inconvenient and inefficient. Second, the sampling scope is limited, and some leaking hoses can easily be mixed in with well-sealed hoses, which poses a potential risk to the overall product quality. Therefore, there is room for improvement. Summary of the Invention

[0006] To facilitate the extrusion leak detection of the sealed hose, this application provides a continuous hose extrusion leak detection device.

[0007] This application provides a continuous hose extrusion leak detection device, which adopts the following technical solution:

[0008] A continuous hose extrusion leak detection device includes a detection conveyor belt, a feeding conveyor belt, a discharge mechanism, and an extrusion mechanism;

[0009] The inspection conveyor belt includes a conveyor belt component, and the outer periphery of the conveyor belt component is provided with several work station compartments, which are used for inserting hoses.

[0010] The material unloading mechanism is located near the input end of the detection conveyor belt and connected to the output end of the feeding conveyor belt, and is used to put the hose from the feeding conveyor belt into the work station compartment of the conveyor belt component.

[0011] The extrusion mechanism is located close to the inspection conveyor belt. The extrusion mechanism includes an extrusion section, which is located above the inspection conveyor belt and can move up and down. When the inspection conveyor belt transports the hose in the work station compartment to a position opposite to the extrusion section, the extrusion section moves downward to extrude the hose in the work station compartment.

[0012] By adopting the above technical solution, the hoses to be tested are transported to the unloading mechanism via the feeding conveyor belt. The unloading mechanism then places the hoses into the workstation bin of the testing conveyor belt. The testing conveyor belt then transports the workstation bin to a position opposite the extrusion plate of the extrusion mechanism. The extrusion plate moves downward to extrude the hoses in the workstation bin. Under the extrusion, the paste inside the leaking hose flows out from the leak point. The extruded hoses are then discharged through the output end of the testing conveyor belt, and subsequently, the leaking hoses are manually removed. Compared with the traditional method of manually sampling and extruding hoses, this method facilitates batch extrusion of hoses, reducing the possibility of product quality issues due to missed inspections. Furthermore, it simplifies the hose extrusion process, making the hose extrusion leak detection operation simpler and more convenient.

[0013] Preferably, the inspection conveyor belt further includes a main beam, with a drive wheel assembly and a driven wheel assembly rotatably mounted at both ends of the main beam, and the conveyor belt component is wound around the drive wheel assembly and the driven wheel assembly; the inspection conveyor belt further includes a drive assembly, which is drivenly connected to the drive wheel assembly to drive the drive wheel assembly to rotate; the outer periphery of the conveyor belt component is connected with a plurality of first side plates and a plurality of second side plates corresponding to the plurality of first side plates, and the plurality of first side plates and the plurality of second side plates are arranged alternately in sequence, with the corresponding first side plates and second side plates forming a workstation compartment.

[0014] By adopting the above technical solution, the drive component drives the drive wheel assembly to rotate, which in turn drives the conveyor belt to rotate cyclically, thereby realizing the cyclic movement of the workstation bin on the conveyor belt. Subsequently, after the unloading mechanism puts the hose into the workstation bin, the first and second side plates on the workstation bin limit the hose to prevent irregular movement of the hose during the conveying process, facilitating the subsequent compression of the hose by the extrusion mechanism.

[0015] Preferably, the material feeding mechanism includes a material feeding bracket, a swing plate is rotatably connected to the material feeding bracket, and a swing drive component is also provided on the material feeding bracket to drive the swing plate to swing back and forth.

[0016] The oscillating plate is provided with an upper storage section and a lower storage section from top to bottom on the side near the feeding conveyor belt. The upper storage section is set below the feeding conveyor belt, and the lower storage section is located above the detection conveyor belt. Both the upper storage section and the lower storage section can be opened and closed.

[0017] When the hose of the feeding conveyor belt enters the upper storage section, the upper storage section opens to allow the hose to fall into the lower storage section; when the hose detaches from the upper storage section, the upper storage section closes; when the swing drive causes the swing plate to swing until the lower storage section is opposite to the work station compartment, the lower storage section opens to allow the hose to fall into the work station compartment; when the hose detaches from the lower storage section, the lower storage section closes.

[0018] By adopting the above technical solution, and with the setting of the upper and lower storage sections, when the hose in the lower storage section has not fallen into the work station compartment, the hose that will be conveyed by the feeding conveyor belt can be temporarily stored in the upper storage section. This achieves temporary storage and buffering of the hose, reducing the situation where two adjacent hoses are too close together and accumulate on the lower storage section after being conveyed by the feeding conveyor belt. This helps to maintain the stable conveying of the hose.

[0019] Preferably, the upper storage section includes two upper limit plates, the bottom side of the upper limit plates is the upper opening and closing side, the upper opening and closing sides of the two upper limit plates abut against each other so that the two upper limit plates are V-shaped, and the upper opening and closing sides of the two upper limit plates can move relative to each other.

[0020] The lower storage section includes two lower limiting plates, the bottom side of which is the lower opening and closing side. The lower opening and closing sides of the two lower limiting plates abut against each other to make the two lower limiting plates form a V shape, and the lower opening and closing sides of the two lower limiting plates can move relative to each other.

[0021] By adopting the above technical solution, the upper storage section can be opened or closed by the relative movement between the upper opening and closing sides of the two sets of upper limit plates, and the lower storage section can be opened or closed by the relative movement between the lower opening and closing sides of the two sets of lower limit plates.

[0022] Preferably, the extrusion mechanism includes an extrusion main support, which is provided with a transverse linear module, which is arranged parallel to the detection conveyor belt; the transverse linear module is driven and connected to a vertical linear module; the vertical linear module is driven and connected to an extrusion sub-support, and the extrusion part includes a plurality of extrusion components, each extrusion component including an extrusion cylinder arranged vertically downward on the extrusion sub-support, and the bottom end of the piston rod of the extrusion cylinder is connected to a pressure head;

[0023] When the inspection conveyor belt transports the hose in the work station compartment to a position opposite the extruder, the vertical linear module drives the extrusion sub-support to move the extruder downwards, and the horizontal linear module drives the extruder to move synchronously with the opposite work station compartment, so as to extrude the hose in the work station compartment through the extruder.

[0024] By adopting the above technical solution, the extrusion cylinder is driven by the horizontal linear module to move synchronously with the work station compartment. This allows the pressure head at the bottom of the extrusion cylinder to remain relatively stationary with the hose inside the work station compartment. This facilitates the vertical linear module driving the extrusion cylinder and pressure head on the extrusion piece to move downwards to extrude the hose inside the work station compartment. With the extrusion cylinder in place, when the vertical linear module drives the extrusion cylinder and pressure head downwards to extrude the hose inside the work station compartment, a properly sealed hose can overcome the cylinder pressure and allow the pressure head to move upwards. A hose with a leaking tail end will have its paste overflow from the leaking point under the pressure of the extrusion cylinder. The extrusion cylinder helps reduce the varying extrusion pressure experienced by the hose inside the work station compartment due to different postures (horizontal or vertical) when the vertical linear module drives the extrusion cylinder and pressure head downwards to extrude the hose, thus reducing the impact on the subsequent extrusion effect. Simultaneously, it provides a buffering effect for the extrusion of the hose inside the work station compartment.

[0025] Preferably, the conveyor belt component includes a first conveyor belt and a second conveyor belt, the first side plate is connected to the outer periphery of the first conveyor belt, and the second side plate is connected to the outer periphery of the second conveyor belt;

[0026] The drive wheel assembly includes a drive shaft rotatably mounted at the end of the main beam, and a first drive wheel, a second drive wheel, and a connecting adjustment assembly are provided on the drive shaft;

[0027] The first drive wheel is coaxially fixed on the drive shaft; the second drive wheel is coaxially rotatably connected to the drive shaft.

[0028] The connecting adjustment assembly includes a worm gear seat, a connecting worm gear, a worm seat, and a connecting worm. The worm gear seat is coaxially fixed on the drive shaft, and an annular limiting groove is coaxially formed on the worm gear seat. The connecting worm gear is coaxially embedded in the annular limiting groove, and the connecting worm gear is connected to the second drive wheel by bolts. A connecting notch is also formed on the outer periphery of the worm gear seat, and the connecting notch communicates with the annular limiting groove. The worm seat is disposed on the connecting notch, and the worm seat has a mounting groove. The connecting worm is rotatably connected to the groove wall of the mounting groove, and the connecting worm meshes with the connecting worm gear.

[0029] The driven wheel assembly includes a driven shaft rotatably mounted at the end of the main beam, and a first driven wheel and a second driven wheel are coaxially rotatably connected on the driven shaft;

[0030] The first conveyor belt is wound around the first driving pulley and the first driven pulley; the second conveyor belt is wound around the second driving pulley and the second driven pulley.

[0031] By adopting the above technical solution and the setting of the connecting adjustment component, on the one hand, when the drive shaft drives the first drive wheel to rotate, the drive shaft can drive the second drive wheel to rotate synchronously with the first drive wheel through the connecting adjustment component, thereby realizing the synchronous transmission of the first and second conveyor belts. On the other hand, it can realize the movement of the second side plate relative to the corresponding first side plate. When the size of the hose changes, the size of the workstation compartment can be adjusted by adjusting the distance between the corresponding first and second side plates, which facilitates the subsequent falling of hoses of different specifications into the workstation compartment and helps to improve the applicability of the inspection conveyor belt. When adjusting the distance between the first and second side plates, by rotating one end of the connecting worm located outside the worm seat, the connecting worm drives the connecting worm wheel and the second drive wheel connected to the connecting worm wheel to rotate relative to the first drive wheel, thereby causing the second drive wheel to drive several second side plates on the second conveyor belt to move relative to the corresponding first side plates on the first conveyor belt, so as to realize the adjustment of the distance between the corresponding first and second side plates.

[0032] Preferably, the worm gear seat is further provided with a clamping member to restrict the rotation of the connecting worm; the clamping member includes a clamping block disposed at the end of the worm gear seat, one end of the clamping block being a connecting end, the connecting end of the clamping block being connected to the end of the worm gear seat and a gap being left between the clamping block and the end of the worm gear seat, a limiting hole being provided on the clamping block, and one end of the connecting worm being rotatably passed through the limiting hole; a clamping bolt is also disposed at the end of the clamping block away from the connecting end, and one end of the clamping bolt is threadedly connected to the end of the worm gear seat.

[0033] By adopting the above technical solution, when it is necessary to restrict the rotation of the connecting worm, the clamping bolts on the clamping block are tightened, and the clamping block is deformed by the clamping bolts, which in turn causes the limiting hole on the clamping block to press against the end of the connecting worm, thus restricting the rotation of the connecting worm. When it is necessary to rotate the connecting worm so that the second driving wheel rotates relative to the first driving wheel, the rotation of the connecting worm can be restored by loosening the clamping bolts, which facilitates the rotation and limiting fixation of the connecting worm.

[0034] Preferably, it also includes a discharge conveyor belt; the output end of the detection conveyor belt is also provided with a flow guide hood, the flow guide hood is sleeved on the outer periphery of the end of the conveyor belt component, the inner periphery of the flow guide hood is adapted to the outer periphery of the end of the conveyor belt component and the inner periphery of the flow guide hood is close to the work station compartment opening at the end of the conveyor belt component, and the discharge conveyor belt is located below the bottom port of the flow guide hood.

[0035] By adopting the above technical solution, the connection between the detection conveyor belt and the discharge conveyor belt is realized through the flow guide hood. After being squeezed by the extrusion mechanism, the hose can be guided to the lower end of the flow guide hood through the cooperation between the work station bin on the conveyor belt and the flow guide hood, and then fall onto the discharge conveyor belt, thus realizing the directional transmission of the hose.

[0036] Preferably, the outer periphery of the first conveyor belt is connected to several first side plates, and the first side plates are connected to the corresponding first material plates; several support wheels are rotatably connected to the bottom of the first material plates, and a first limiting track is erected parallel to the upper surface of the main beam, and the support wheels are embedded in the first limiting track.

[0037] By adopting the above technical solution, on the one hand, the support of the first material loading plate is achieved through the cooperation between the support wheel and the limiting track, which helps to improve the rigidity of the bottom of the work station compartment and reduce the situation where the first conveyor belt is subjected to force and sinks when the subsequent extrusion section moves down to extrude the hose in the work station compartment, causing the work station compartment to move downward and affecting the extrusion effect of the hose in the work station compartment.

[0038] Preferably, the input end of the detection conveyor belt is provided with a limit baffle and a guide plate on opposite sides, respectively. The guide plate is located between the unloading mechanism and the extrusion mechanism. The guide plate is provided with a guide slope on the side facing the limit baffle. The distance between the guide slope and the limit baffle gradually decreases from the end near the unloading mechanism to the end away from the unloading mechanism. Both the first side plate and the second side plate are provided with guide notches at the ends near the guide plate for the guide plate to pass through.

[0039] By adopting the above technical solution, the position of the hose in the work station compartment can be adjusted by the guide plate during the conveying process, so that the ends of the hoses in adjacent work station compartments can be aligned with each other. This reduces the situation where the positions of the hoses in subsequent adjacent work station compartments are different, resulting in different extrusion forces when the extrusion mechanism extrudes the hoses in the work station compartments, which affects the extrusion effect of the hoses.

[0040] In summary, this application includes at least one of the following beneficial technical effects:

[0041] 1. When inspecting hoses, the hoses to be inspected are fed into the unloading mechanism via the feeding conveyor belt. The unloading mechanism places the hoses into the work station bin of the inspection conveyor belt. The inspection conveyor belt then transports the hoses in the work station bin to the position opposite the extrusion section of the extrusion mechanism. The extrusion section moves downward to extrude the hoses in the work station bin. After extrusion, the hoses are conveyed out via the inspection conveyor belt. This process enables automatic batch extrusion of hoses, facilitating leak detection.

[0042] 2. Through the setting of the unloading mechanism, the hose from the feeding conveyor belt first falls into the upper storage section of the unloading mechanism, then the upper storage section puts it into the lower storage section, and finally the lower storage section puts the hose into the work station bin. When the lower storage section has not put the hose into the work station bin, the hose from the feeding conveyor belt can be temporarily stored in the upper storage section. This helps to reduce the situation where the hoses on the feeding conveyor belt are too close together, causing the hoses to fall into the lower storage section in a concentrated manner. It is convenient to temporarily store and buffer the hoses from the feeding conveyor belt, which is conducive to the stable unloading of the unloading mechanism.

[0043] 3. The extrusion component includes an extrusion cylinder vertically mounted on an extrusion sub-support. The piston rod of the extrusion cylinder is connected to a pressure head. When the subsequent vertical linear module drives the extrusion cylinder to move the pressure head downward to extrude the hose in the work station compartment, the hose that is properly sealed can overcome the pressure of the extrusion cylinder and push the pressure head and the piston rod of the cylinder upward. The paste in the hose that is leaking will leak out from the leak point under the pressure of the extrusion cylinder. The extrusion cylinder can reduce the situation where the hoses in adjacent work station compartments have different postures, resulting in different stress conditions and affecting the extrusion results.

[0060] The following is in conjunction with the appendix Figure 1-14 This application will be described in further detail.

[0061] This application discloses a continuous hose extrusion leak detection device, referring to... Figure 1 and Figure 2 The system includes a workbench 1, a testing conveyor belt 2, a feeding conveyor belt 3 and a discharging conveyor belt 4, a dropping mechanism 5, and a pressing mechanism 6. The testing conveyor belt 2 is installed on the workbench 1 and includes a conveyor belt component 21. Several workstations 210 for inserting hoses are arranged around the outer periphery of the conveyor belt component 21. The output end of the feeding conveyor belt 3 is close to the input end of the testing conveyor belt 2. The input end of the discharging conveyor belt 4 is connected to the output end of the testing conveyor belt 2 and is used to transfer the hoses transmitted from the testing conveyor belt 2. The dropping mechanism 5 is close to the input end of the testing conveyor belt 2 and the output end of the feeding conveyor belt 3 and is used to insert the hoses transmitted from the feeding conveyor belt 3 into the workstations 210 on the conveyor belt component 21. The pressing mechanism 6 has a pressing part that is arranged to move up and down. When the testing conveyor belt 2 transmits the hoses in the workstations 210 to the pressing part, the pressing part moves downward to press the hoses in the workstations 210.

[0062] Reference Figure 1 and Figure 2 The inspection conveyor belt 2 also includes a main beam 20, a drive wheel assembly 22, a driven wheel assembly, and a drive assembly 23. The drive wheel assembly 22 and the driven wheel assembly are respectively rotatably mounted on both ends of the main beam 20. The conveyor belt 21 is wound around the drive wheel assembly 22 and the driven wheel assembly. The drive assembly 23 is driven and connected to the drive wheel assembly 22 to drive the drive wheel assembly 22 to rotate. With the above configuration, the drive assembly 23 drives the drive wheel assembly 22 to rotate, and the drive wheel assembly 22 and the driven wheel assembly cooperate to realize the cyclic movement of the workstation 210 on the conveyor belt 21.

[0063] Reference Figure 3 and Figure 4 The outer periphery of the conveyor belt component 21 is vertically provided with a number of first side plates 211 and a number of second side plates 212. The number of first side plates 211 and the number of second side plates 212 are arranged alternately in sequence. The number of first side plates 211 and the number of second side plates 212 correspond one to one. The corresponding first side plates 211 and second side plates 212 form a work station compartment 210. The corresponding first side plates 211 and second side plates 212 extend inclinedly in a direction away from each other, so that the top opening of the work station compartment 210 forms a flared shape, which makes it easier for the subsequent hose to fall into the work station compartment 210.

[0064] The conveyor belt component 21 includes a first conveyor belt 213 and two second conveyor belts 214. A plurality of first material carrier plates 215 are fixed on the first conveyor belt 213 corresponding to a plurality of first side plates 211. A plurality of second material carrier plates 216 are fixed on the second conveyor belts 214 corresponding to a plurality of second side plates 212. The plurality of second material carrier plates 216 on the second conveyor belts 214 correspond one-to-one with the plurality of first material carrier plates 215 on the first conveyor belts 213.

[0065] The first side plate 211 is fixed to one side of the first carrying plate 215, and both ends of the first side plate 211 extend to the corresponding second carrying plates 216 of the two second conveyor belts 214. The second side plate 212 spans the first carrying plate 215, and both ends of the second side plate 212 are fixed to the sides of the corresponding second carrying plates 216 on the two second conveyor belts 214, thereby achieving a stable connection between the first side plate 211 and the second side plate 212 and the conveyor belt component 21.

[0066] Reference Figure 5 and Figure 6 The first material carrier plate 215 extends from both sides of the first conveyor belt 213 to the opposite sides. Several support wheels 2151 are rotatably connected to the bottom of both sides of the first material carrier plate 215. The rotation axis of the support wheels 2151 is perpendicular to the length direction of the main beam 20. A support plate 202 is mounted parallel to the upper surface of the main beam 20. Two first limiting rails 203 are fixed on the upper surface of the support plate 202. The length direction of the first limiting rails 203 is parallel to the length of the main beam 20. The support wheels 2151 on the opposite sides of the first material carrier plate 215 above the main beam 20 are respectively embedded in the two first limiting rails 203. There is a gap between the inner circumference of the first conveyor belt 213 and the first limiting rail 203. With the above settings, on the one hand, the friction between the first conveyor belt 213 and the main beam 20 can be reduced by the cooperation between the support wheel 2151 and the first limiting rail 203; on the other hand, the support wheel 2151 can support the first material plate 215, which is conducive to improving the rigidity of the bottom of the work station hopper 210 and limiting the deformation of the first conveyor belt 213 when the subsequent extrusion part presses down to extrude the hose in the work station hopper 210, thus affecting the extrusion effect of the hose in the work station hopper 210.

[0067] The lower surface of the main beam 20 is connected to two opposing hook plates 205. The bottom sides of the two hook plates 205 are bent at 90° to form bent ends. The bent ends of the two hook plates 205 are positioned opposite each other. The first material loading plate 215 located on the lower surface of the main beam 20 has its two supporting wheels 2151 respectively hooked onto the bent ends of the two hook plates 205.

[0068] The upper surface of the support plate 202 is fixed with two second limiting rails 204 corresponding to the two second conveyor belts 214; the two second conveyor belts 214 are respectively embedded in the two second limiting rails 204.

[0069] Reference Figure 7 and Figure 8 The drive wheel assembly 22 includes a drive shaft 221. Two main bearing seats are connected to opposite sides of one end of the main beam 20 near the drive wheel assembly 22. Both ends of the drive shaft 221 are rotatably mounted on the two main bearing seats via bearings, thus rotatably mounting the drive shaft 221 at the end of the main beam 20. A first drive wheel 222 is coaxially fixed on the drive shaft 221. Two second drive wheels 223 are also coaxially rotatably connected to the drive shaft 221. The two second drive wheels 223 are located on opposite sides of the first drive wheel 222, and each of the two second drive wheels 223 corresponds to one of the two second transmission belts 214.

[0070] The two second drive wheels 223 are connected by four sets of connecting rods 224, which are evenly distributed around the axis of the second drive wheel 223. The first drive wheel 222 has four sets of arc-shaped elongated holes 2221 corresponding to the four sets of connecting rods 224. The four sets of connecting rods 224 are respectively inserted into the four sets of arc-shaped elongated holes 2221, which are used to allow the connecting rods 224 to slide around the axis of the drive shaft 221.

[0071] Reference Figure 8 and Figure 9 The drive shaft 221 is also provided with a connecting adjustment assembly 225. The connecting adjustment assembly 225 is located on one side of the second drive wheel 223. The connecting adjustment assembly 225 includes a worm gear seat 2251, a connecting worm gear 2253, a worm seat 2254, and a connecting worm 2255. The worm seat 2254 is coaxially fixed on the drive shaft 221. The worm seat 2254 has an annular limiting groove 2252 coaxially opened on the side facing the second drive wheel 223. The connecting worm gear 2253 is coaxially embedded in the annular limiting groove 2252. The connecting worm gear 2253 is fixed on the second drive wheel 223 by several bolts. The outer periphery of the worm gear mounting base is provided with a connecting notch, which communicates with the annular limiting groove 2252; the worm seat 2254 is fixed on the connecting notch, the worm seat 2254 has a mounting groove and the mounting groove communicates with the annular limiting groove 2252, the two ends of the connecting worm 2255 are rotatably connected to the two end walls of the mounting groove and the connecting worm 2255 meshes with the connecting worm wheel 2253, one end of the connecting worm 2255 extends to the outside of the end of the worm seat 2254 and the end of the connecting worm 2255 extending out of the end of the worm seat 2254 is provided with an internal hexagonal hole.

[0072] Reference Figure 2 and Figure 8 The drive assembly 23 includes a drive motor, the output end of which is coaxially fixed with one end of the drive shaft 221.

[0073] The driven wheel assembly includes a driven shaft, and two auxiliary bearing seats are connected to opposite sides of one end of the main beam 20 near the driven wheel assembly. Both ends of the driven shaft are connected to the auxiliary bearing seats via bearings, enabling the driven shaft to rotate. Mounted at the end of the main beam 20, the driven shaft is coaxially connected to a first driven wheel and two second driven wheels. The two second driven wheels are located on opposite sides of the first driven wheel, and each of the two second driven wheels corresponds to one of the two second transmission belts 214.

[0074] Reference Figure 8 and Figure 9 The first conveyor belt 213 is wound around the first driving wheel 222 and the first driven wheel, and the second conveyor belt 214 is wound around the corresponding second driving wheel 223 and the second driven wheel.

[0075] With the above settings, when the inspection conveyor belt 2 is running, the drive motor drives the drive shaft 221 to rotate. The drive shaft 221 drives the first drive wheel 222 and at the same time drives the second drive wheel 223 to rotate synchronously with the first drive wheel 222 through the connecting adjustment component 225, thereby realizing the cyclic movement of several workstations 210 on the inspection conveyor belt 2.

[0076] The connection adjustment component 225 serves two purposes: firstly, the drive shaft 221 can drive two second drive wheels 223 to rotate synchronously with the first drive wheel 222 via the connection adjustment component 225; secondly, it can also move the second side plate 212 on the second conveyor belt 214 relative to the corresponding first side plate 211 on the first belt, thereby adjusting the size of the workstation hopper 210 and improving the applicability of the inspection conveyor belt 2. When adjusting the position of the second side plate 212, the connecting worm 2255 is rotated by rotating one end extending from the worm seat 2254. When the connecting worm 2255 rotates, it drives the second drive wheel 223 to rotate via the connecting worm wheel 2253. The second drive wheel 223 then moves the second conveyor belt 214 relative to the first conveyor belt 213, causing the second side plate 212 to move relative to the corresponding first side plate 211, thus adjusting the size of the workstation hopper 210.

[0077] In this embodiment, the first driving pulley 222, the second driving pulley 223, the first driven pulley, and the second driven pulley are all toothed pulleys, and the first transmission belt 213 and the second transmission belt 214 are both gear belts, which facilitates the improvement of the connection between the first driving pulley 222, the first driven pulley and the first transmission belt 213, and the connection between the second driving pulley 223 and the second driven pulley and the second transmission belt 214.

[0078] The worm gear seat 2254 is also provided with a clamping member for limiting the rotation of the connecting worm 2255. The clamping member includes a clamping block 2256 disposed at the end of the worm gear seat 2254. One end of the clamping block 2256 is a connecting end, and the connecting end of the clamping block 2256 is fixedly connected to the end of the worm gear seat 2254. A gap is left between the clamping block 2256 and the end of the worm gear seat 2254. A limiting hole 2257 is provided at one end of the clamping block 2256 near the connecting end. The end of the connecting worm 2255 with an internal hexagonal hole rotatably passes through the limiting hole 2257. A clamping bolt 2258 is also provided at the end of the clamping block 2256 away from the connecting end. The end of the clamping bolt 2258 is threaded to the end of the worm seat 2254. With this configuration, when it is necessary to restrict the rotation of the connecting worm 2255, tightening the clamping bolt 2258 causes the wall of the limiting hole 2257 in the clamping block 2256 to press against the end of the connecting worm 2255, thus limiting the rotation of the connecting worm 2255. When it is necessary to rotate the connecting worm 2255, loosening the clamping bolt 2258 restores the rotation of the connecting worm 2255.

[0079] Reference Figure 2 and Figure 3 Limiting baffles 201 and guide plates 200 are respectively provided on opposite sides of the conveying end of the detection conveyor belt 2. The limiting baffles 201 are vertically connected to one side of the main beam 20. The guide plates 200 are mounted on one side of the main beam 20 and are located between the unloading mechanism 5 and the extrusion mechanism 6. A guide slope is provided on the side of the guide plates 200 facing the limiting baffles 201. The distance between the guide slope and the limiting baffles 201 gradually decreases from the end near the unloading mechanism 5 to the end away from the unloading mechanism 5. The end of the guide plates 200 away from the unloading mechanism 5 extends to the top of the conveyor belt component 21. Both the first side plate 211 and the second side plate 212 have guide notches 217 for the guide plates 200 to pass through at the end near the guide plates 200. By setting the guide plate 200, when the conveyor belt 2 transmits the hose to the extrusion mechanism 6, the position of the hose in the work station 210 can be adjusted by the guide slope on the guide plate 200, so that the ends of the hoses in adjacent work station 210 are flush. This reduces the situation where the hoses are subjected to different pressures due to the different positions of the hoses in adjacent work station 210 when the extrusion part is moved down to extrude the hoses, which affects the extrusion result of the hoses.

[0080] Reference Figure 1 and Figure 10 The conveying directions of both the feed conveyor belt 3 and the discharge conveyor belt 4 are perpendicular to the conveying direction of the detection conveyor belt 2.

[0081] Reference Figure 1 and Figure 10The material discharge mechanism 5 is positioned opposite to the output end of the feeding conveyor belt 3. The material discharge mechanism 5 includes a material discharge bracket 51, the bottom of which is fixedly connected to the side of the main beam 20. A swing plate 52 is rotatably connected to the bottom end of the material discharge bracket 51. The swing plate 52 is located above the conveyor belt component 21 of the detection conveyor belt 2, and the rotation axis of the swing plate 52 is perpendicular to the conveying direction of the detection conveyor belt 2. The material discharge bracket 51 is also provided with a swing drive component that drives the swing plate 52 to swing back and forth. In this embodiment, the swing drive component is a swing motor, and the output end of the swing motor is coaxially fixed with the swing plate 52.

[0082] Reference Figure 10 and Figure 11 The oscillating plate 52, facing the end of the feeding conveyor belt 3, is provided with an upper storage section 53 and a lower storage section 54 arranged sequentially from top to bottom. The upper storage section 53 is lower than the output end of the feeding conveyor belt 3, allowing the flexible hose from the feeding conveyor belt 3 to fall into the upper storage section 53. The upper storage section 53 is openable and closable. The lower storage section 54 is located above the input end of the detection conveyor belt 2. The lower storage section 54 is also openable and closable.

[0083] The upper storage section 53 includes two upper limit plates 531 arranged in a V-shape. The bottom sides of the two upper limit plates 531 are upper opening and closing sides, and the upper opening and closing sides of the two upper limit plates 531 are abutted against each other. The swing plate 52 is also provided with an upper opening and closing drive member. The upper opening and closing drive member is used to drive the upper opening and closing sides of the two upper limit plates 531 to move away from each other or move closer to each other, so that the upper opening and closing sides of the two upper limit plates 531 can move relative to each other, so as to realize the opening or closing of the upper opening and closing section.

[0084] Both upper limit plates 531 have upper drive rods 530 connected to their top sides, and the upper drive rods 530 are rotatably mounted on the swing plate 52 via bearings. The upper opening and closing drive component is located on the side of the swing plate 52 opposite to the feeding conveyor belt 3. The upper opening and closing drive component includes a first sector gear 533 and a first sector gear 533. The first sector gear 533 and the first sector gear 533 are respectively fixed to the ends of the upper drive rods 530 on the two upper limit plates 531, and the two sector gears 533 are meshed together. The upper opening and closing drive component also includes a first drive cylinder 534. One end of the first drive cylinder 534 is hinged to the support plate 202, and the other end of the first drive cylinder 534 is hinged to the first sector main gear 532. The rotation axes of the two ends of the first drive cylinder 534 are parallel to the rotation axis of the upper drive rod 530. The piston rod of the first drive cylinder 534 can be extended and retracted to drive the two upper limit plates 531 to swing, thereby realizing the relative movement of the upper opening and closing sides of the two upper limit plates 531.

[0085] The lower storage section 54 includes two lower limit plates 541 arranged in a V-shape. The bottom sides of the two lower limit plates 541 are lower opening and closing sides, and the lower opening and closing sides of the two lower limit plates 541 are abutted against each other. The swing plate 52 is also provided with a lower opening and closing drive member. The lower opening and closing drive member is used to drive the opening and closing sides of the two lower limit plates 541 to move away from each other or move closer to each other, so that the opening and closing sides of the two lower limit plates 541 can move relative to each other, so as to realize the opening and closing of the lower storage section 54.

[0086] Both lower limit plates 541 are connected to the top side of a lower drive rod 540, and the lower drive rod 540 is rotatably mounted on the swing plate 52 via a bearing. The lower opening and closing drive component is located on the side of the swing plate 52 away from the feeding conveyor belt 3. The lower opening and closing drive component includes a second sector main gear 542 and a second sector auxiliary gear 543. The second sector main gear 542 and the second sector auxiliary gear 543 are respectively fixed to the ends of the lower drive rods 540 of the two lower limit plates 541, and the two sector main gears 542 and the second sector auxiliary gears 543 are meshed. The lower opening and closing drive component also includes a second drive cylinder 544. One end of the second drive cylinder 544 is hinged to the support plate 202, and the other end of the second drive cylinder 544 is hinged to the lower sector main gear 542. The rotation axes of the two ends of the second drive cylinder 544 are parallel to the rotation axis of the lower drive rod 540. By driving its own piston rod to extend and retract, the two lower limit plates 541 can be driven to swing, thereby realizing the relative movement of the lower opening and closing sides of the two lower limit plates 541.

[0087] Reference Figure 1 and Figure 10 When the feed conveyor belt 3 delivers the hose to the upper storage section 53, the upper opening and closing drive causes the two upper limit plates 531 to swing, so that the opening and closing sides of the two upper limit plates 531 move away from each other, thereby opening the upper storage section 53. This allows the hose in the upper storage section 53 to detach from the upper storage section 53 and fall into the lower storage section 54. After the hose in the upper storage section 53 detaches from the upper storage section 53, the upper opening and closing drive causes the two upper limit plates 531 to swing, so that the upper opening and closing sides of the two upper limit plates 531 move closer to each other until the upper opening and closing sides of the two upper limit plates 531 abut against each other, thereby closing the upper storage section 53.

[0088] When the swing drive 521 drives the swing plate 52 to swing until the lower storage section 54 is opposite to the work station 210 on the inspection conveyor belt 2, the lower opening and closing drive drives the two lower limit plates 541 to swing so that the lower opening and closing sides of the two lower limit plates 541 move away from each other, thereby opening the lower storage section 54 and allowing the hose inside the lower storage section 54 to fall into the work station 210. After the hose inside the lower storage section 54 is detached from the lower storage section 54, the lower opening and closing drive drives the two lower limit plates 541 to swing so that the lower opening and closing sides of the two lower limit plates 541 move closer to each other until the lower opening and closing sides of the two lower limit plates 541 abut against each other, thereby closing the lower storage section 54 and facilitating the subsequent opening of the upper storage section 53 to allow the hose to fall into the lower storage section 54.

[0089] With the above settings, when the hose in the lower storage section 54 has not fallen into the work station hopper 210, the hose from the output end of the feeding conveyor belt 3 can first fall into the upper storage section 53, realizing the buffering and temporary storage of the hose. This helps to reduce the situation where adjacent hoses on the feeding conveyor belt 3 are too close together, causing the hoses to fall into the lower storage section 54 in a concentrated manner, thus facilitating the stable falling of the hose.

[0090] In this embodiment, the second drive cylinder 544 is a cylinder with adjustable stroke. After the size of the subsequent work station compartment 210 is adjusted, the stroke of the second drive cylinder 544 is adjusted to adjust the swing angle of the two lower limit plates 541, so that the hose in the subsequent lower storage part 54 can fall into the work station compartment 210 better.

[0091] Reference Figure 12 and Figure 13 The extrusion mechanism 6 includes an extrusion main support 61, the bottom of which is fixed to one side of the main beam 20. A transverse linear module 62 is mounted on the top of the extrusion main support 61. The transverse linear module 62 is arranged parallel to the inspection conveyor belt 2. A vertical linear module 63 is also vertically arranged on the transverse linear module 62. The frame of the vertical linear module 63 is connected to the slide of the transverse linear module 62, realizing the driving connection between the transverse linear module 62 and the vertical linear module 63. In this embodiment, both the transverse linear module 62 and the vertical linear module 63 are existing electric lead screw linear modules. An extrusion sub-support 64 is also provided on the vertical linear module 63, and the extrusion sub-support 64 is connected to the slide of the vertical linear module 63, realizing the driving connection between the vertical linear module 63 and the extrusion sub-support 64. The extrusion section includes several extrusion components 60. Each extrusion component 60 includes an extrusion cylinder 601 that is vertically mounted on the top of a third support. The bottom end of the piston rod of the extrusion cylinder 601 is connected to a pressure rod 602, and the bottom end of the pressure rod 602 is connected to a pressure head 603 via a connector.

[0092] Reference Figure 1 and Figure 12With the above setup, when the conveyor belt 2 transports the hoses from several workstation compartments 210 to the pressure heads 603 at the bottom of several extrusion cylinders 601, the vertical drive module drives the extrusion cylinders 601 on the extrusion sub-support 64 to move downwards. The pressure heads 603 at the bottom of the extrusion cylinders 601 then extrude the hoses in the workstation compartments 210. The horizontal linear module 62 drives the vertical linear module 63 to move the extrusion cylinders 601 along with the corresponding workstation compartments 210, keeping the extrusion cylinders 601 and the corresponding workstation compartments 210 relatively stationary. After extrusion is complete, the vertical linear module 63 drives the extrusion cylinders 601 to move the pressure heads 603 upwards, while the horizontal linear module 62 drives the vertical linear module to reset to its starting position.

[0093] With the extrusion cylinder 601 in place, when the subsequent vertical linear module 63 drives the extrusion cylinder 601 downwards to pass through the bottom of the extrusion cylinder 601, the well-sealed hose in the work station compartment 210 can overcome the pressure of the extrusion cylinder 601 and lift the pressure head 603 and the piston rod of the extrusion cylinder 601. Any ointment in the leaking hose will overflow from the leak point under the pressure of the extrusion cylinder 601. This helps reduce the possibility of extrusion errors caused by different hose postures (horizontal or vertical) within the work station compartment 210, which can result in varying extrusion forces on the hose when the extrusion section presses it down.

[0094] The connector includes a connecting plate vertically connected to the bottom of the pressure rod 602. The connecting plate is bolted to the top of the pressure head 603, so that the pressure head 603 can be detachably connected to the pressure rod 602. This allows the pressure head 603 to be better squeezed after the size of the work station 210 is adjusted, so that the pressure head 603 can be better adapted to the work station 210.

[0095] All pressure rods 602 are slidably connected to the compression sub-support 64 through a slider rail structure. The compression sub-support 64 can assist in supporting the pressure rods 602, which helps to improve the overall strength and bending resistance of the pressure rods 602.

[0096] The main extrusion support 61 is equipped with several pressure regulating valves 65 corresponding to several extrusion cylinders 601. The several regulating valves are connected to the corresponding extrusion cylinders 601 through air pipes, so that the pressure of the extrusion cylinders 601 can be adjusted by the pressure regulating valves 65.

[0097] Reference Figure 1 and Figure 14The output end of the inspection conveyor belt 2 is also equipped with a flow guide hood 24, which is fitted onto the end of the conveyor belt component 21. The flow guide hood 24 is semi-circular, and its inner circumference is adapted to the outer contour of the end of the conveyor belt component 21. The inner circumference of the flow guide hood 24 is located near the opening of the work station compartment 210 at the end of the conveyor belt component 21. The gap between the opening of the work station compartment 210 and the inner circumference of the flow guide hood 24 is less than the thickness of the hose. The input end of the discharge conveyor belt 4 is located directly below the bottom port of the flow guide hood 24. With the above configuration, the hose that has been extruded in the subsequent work station compartment 210 can be guided by the flow guide hood 24 to the top of the discharge conveyor belt 4 and fall into the discharge conveyor belt 4, which is beneficial for the directional conveying of the hose.

[0098] The guide shroud 24 has mounting notches on both outer sides for embedding the main bearing seats. The guide shroud 24 is attached to the two main bearing seats on both sides through the mounting notches. The guide shroud 24 is provided with connecting pieces on both sides. The connecting pieces are connected to the main bearing seats by bolts, so that the guide shroud 24 can be detachably connected to the output end of the detection conveyor belt 2.

[0099] The implementation principle of this application embodiment is as follows: The hose to be extruded is fed into the unloading mechanism 5 via the feeding conveyor belt 3. The unloading mechanism 5 places the hose into the station compartment 210 of the detection conveyor belt 2. The detection conveyor belt 2 then transports the hose in the station compartment 210 to a position opposite the extrusion piece 60 of the extrusion mechanism 6. The vertical linear module 63 drives the extrusion cylinder 601 of the extrusion piece 60 to move downward, and the horizontal linear module 62 drives the vertical linear module 63 to move the extrusion cylinder 601 synchronously with the station compartment 210, so that the pressure head 603 at the bottom of the extrusion cylinder 601 extrudes the hose in the station compartment 210. After extrusion, the vertical linear module 63 drives the extrusion cylinder 601 to move upward and reset, and the horizontal linear module 62 drives the vertical linear module to reset to the starting end of the horizontal linear module 62. The extruded hose is fed into the discharge conveyor belt 4 via the detection conveyor belt 2 and the guide shroud 24, and then discharged via the discharge conveyor belt 4.

[0100] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
