Description

Technical Field

[0001] The present application relates to the technical field of corrugated pipe forming equipment, and in particular to a drainage corrugated pipe extrusion manufacturing equipment and a method for detecting the length of the corrugated pipe. Background Art

[0002] The corrugated pipe used for air conditioning drainage includes an inserting portion, a connecting portion and a matching portion, wherein the connecting portion is connected to the inserting portion and the matching portion, the pipe opening diameter of the inserting portion is smaller than the pipe opening diameter of the connecting portion, and the pipe opening diameter of the matching portion is larger than the pipe opening diameter of the connecting portion. Since both the inserting portion and the matching portion of the corrugated pipe need to be tightly connected with other pipes, it is necessary to strictly control the length of the corrugated pipe to ensure the connection effect.

[0003] When manufacturing plastic corrugated pipes, the raw materials are first heated to a molten state, and then the molten plastic is fed into a molding die, where it is blown into shape by the air duct. During this process, the molding die is completely compatible with the corrugated pipe, and can produce continuous tube blanks at the same time. After the tube blanks cool down, they are cut into standard corrugated pipe sections with the help of a cutting machine.

[0004] However, in the actual production process, when the tube blank is cut by a cutting machine, deviations often occur. At this time, manual selection is usually adopted to measure the length of each corrugated tube and screen out excellent products. This leads to problems such as heavy workload, high labor intensity and low efficiency. Summary of the invention

[0005] In order to improve the degree of automation in screening the length of a corrugated pipe, the present application provides a drainage corrugated pipe extrusion manufacturing device and a method for detecting the length of the corrugated pipe.

[0006] In the first aspect, the present application provides a drainage corrugated pipe extrusion manufacturing device, which adopts the following technical solution: A drainage corrugated pipe extrusion manufacturing device, comprising: a frame; A traction mechanism is fixed on the frame, and the traction mechanism includes an upper guide wheel and a lower guide wheel. The upper guide wheel and the lower guide wheel are arranged opposite to each other, and a pipe-threading gap is left between the two. An elastic module is arranged between the upper guide wheel and the lower guide wheel, and the elastic module is used to adjust the pipe-threading gap between the upper guide wheel and the lower guide wheel. The tube blank passes through the tube-threading gap. The upper guide wheel and the lower guide wheel cooperate to actively pull the tube blank forward for transportation; A cutting mechanism, fixed on the frame and distributed at the output end of the traction mechanism, for cutting the tube blank into corrugated tube segments; The quality inspection mechanism is fixed on the frame and distributed at the output end of the breaking mechanism, and is used for clamping and delivering the corrugated pipe segments and for length inspection.

[0007] By adopting the above technical solution, an adjustable pipe threading gap is formed under the cooperation of the upper guide wheel, the lower guide wheel and the elastic module, and the size of the pipe threading gap can be flexibly adjusted to adapt to pipes of different diameters or pipes of different diameters at the same time, providing continuous traction for the pipes, ensuring the stability and smoothness of the pipes during the traction process, and improving the versatility of the equipment.

[0008] Under the action of the cutting mechanism, the tube blank can be cut into corrugated pipe sections. Automated cutting greatly reduces the complexity and labor intensity of manual operation, thereby achieving the purpose of improving production efficiency. The corrugated pipe sections are then automatically clamped and length-detected by the quality inspection mechanism to ensure that the length of each corrugated pipe section is consistent. The online quality inspection method can promptly detect and handle unqualified products, which helps to improve the overall product quality level and the degree of product standardization.

[0009] Preferably, it comprises: a feeding mechanism, arranged at the output end of the frame, for storing materials and automatically feeding; The forming mechanism is fixed on the frame and distributed at the output end of the feeding mechanism. The forming mechanism includes a heating module and a forming module. The heating module is used to heat the solid material into a molten material, and the forming module forms the molten material into a tube blank.

[0010] By adopting the above technical solution, under the action of the feeding mechanism, the automatic storage and feeding functions of the materials are realized, making the production process more continuous and efficient, reducing the links of manual handling and adding materials, helping to reduce labor intensity and improve production efficiency. The solid material can be quickly heated to a molten state through the heating module, providing a uniform material temperature for the subsequent molding process, ensuring the molding quality of the tube blank.

[0011] Preferably, it includes a cooling mechanism, which is fixed on the frame and distributed at the output end of the forming mechanism. The cooling mechanism includes a cooling module and an output traction module. The cooling module is used to cool the tube blank. The output traction module is used to actively pull the tube blank forward for transportation. The traction mechanism is arranged at the output end of the cooling mechanism.

[0012] By adopting the above technical solution, the cooling module can instantly cool the tube billet just out of the mold, so that the tube billet can be quickly formed and reach the ideal temperature state, reducing the deformation or quality problems of the tube billet due to overheating. At the same time, under the action of the output traction module, the cooled tube billet can be smoothly and continuously transported to the next processing link, reducing the pause and waiting time in the production process, thereby improving the continuity and efficiency of the overall production process.

[0013] Preferably, the quality inspection mechanism includes a rodless cylinder, a slider, a segmenting rod, and a distance sensor, wherein the segmenting rod is provided with a hollow groove along its length direction, the tube blank passes through the hollow groove, the bottom of the slider is assembled with the output end of the rodless cylinder, the segmenting rod is assembled on the top of the slider, and the distance sensor is fixed on the frame for calculating the movement stroke of the slider.

[0014] By adopting the above technical solution, the rodless cylinder, slider, segment rod and distance sensor are integrated to build an accurate and efficient quality inspection system. The tube billet passes through the hollow groove on the segment rod without obstacles, ensuring the stable position of the tube billet during the inspection process. At the same time, the segment rod is used as the reference point for inspection. With the cooperation of the rodless cylinder and the slider, the segment rod can be moved smoothly and controllably. The distance sensor accurately calculates the movement stroke of the slider, which can achieve high-precision measurement of the length of the tube billet. The entire quality inspection process has a high degree of automation, reducing human intervention and errors.

[0015] Preferably, the elastic force module includes a power component and an elastic force component, the power component includes a first connecting shaft rotatably connected to the side wall of the frame; a driving gear mounted on the outer wall of the first connecting shaft; a swing block connected to the outer wall of the first connecting shaft by a bearing; a second connecting shaft rotatably connected to the swing block; a driven gear mounted on the outer wall of the second connecting shaft; a power piece mounted on the end of the first connecting shaft, wherein the driving gear is meshed with the driven gear, the power piece serves as a power source to drive the first connecting shaft to rotate, and the upper guide wheel is mounted on an end of the second connecting shaft away from the side wall of the frame; There are two power components and one elastic component. The lower guide wheel is assembled on the other end of the second connecting shaft so that the upper guide wheel and the lower guide wheel are vertically opposite to each other. The elastic component includes a buffer connected between the two pendulum blocks.

[0016] By adopting the above technical scheme, two groups of power components and elastic components are set to control the upper guide wheel and the lower guide wheel respectively, that is, the power component acts as a power source to drive the first connecting shaft to rotate, and the first connecting shaft drives the driving gear to rotate, thereby driving the driven gear and the second connecting shaft to rotate. Since the pendulum block and the second connecting shaft, and the pendulum block and the first connecting shaft are fixed by bearing connection, the pendulum block can swing to a certain extent, and the buffer member connected between the two pendulum blocks plays the role of shock absorption, buffering and linkage, so that both the upper guide wheel and the lower guide wheel have the ability to rotate and adjust the position at the same time, so as to adjust the spacing between the upper guide wheel and the lower guide wheel, so as to achieve the purpose of flexibly controlling the pipe threading gap, so that it can adapt to pipe blanks of different diameters or pipe blanks with different pipe diameters at the same time, provide continuous traction for the pipe blanks, ensure the stability and smoothness of the pipe blanks during traction, improve the versatility of the equipment, effectively reduce the vibration and noise of the equipment during operation, and improve the working stability and reliability of the equipment.

[0017] Preferably, it includes an elastic module, which is fixedly arranged on the frame, wherein the elastic module includes a fixed seat fixed on the top surface of the frame; a guide rod installed on the top surface of the fixed seat; a matching block slidably connected to the guide rod; a buffer spring sleeved on the outer wall of the guide rod and distributed between the fixed seat and the matching block; an upper rotating wheel rotatably connected to the side wall of the fixed seat; and a lower rotating wheel rotatably connected to the side wall of the matching block, the upper rotating wheel and the lower rotating wheel are arranged opposite to each other up and down, and a pipe supply gap is left between the two, and the pipe blank passes through the pipe supply gap.

[0018] By adopting the above technical scheme, the fixed seat, guide rod, matching block and buffer spring work together to form an efficient elastic module, so that the upper rotary wheel and the lower rotary wheel are distributed opposite each other and the relative position of the two is guaranteed to be stable. In addition, the buffer spring provides an elastic adjustment function for the pipe supply gap between the two. When the tube blank passes through the pipe supply gap, the buffer spring can be adaptively adjusted according to the diameter change of the tube blank to ensure that the pipe supply gap is always maintained in the best state, effectively reducing the jamming or damage problems caused by uneven or changing diameter of the tube blank, which helps to improve the smoothness of the production process and the stability of product quality.

[0019] Preferably, it comprises an input traction module, which is fixed on the frame and distributed between the output traction module and the traction mechanism, and is used to provide positioning and guidance for the tube blank before it enters the traction mechanism.

[0020] By adopting the above technical solution, before the tube billet enters the traction mechanism, the input traction module can provide it with precise positioning and guiding functions, so that the tube billet can enter the traction mechanism in the correct position and state, effectively reducing the problems of equipment jamming or damage caused by improper entry of the tube billet, which helps to improve the continuity and efficiency of the production process.

[0021] In a second aspect, the present application provides a method for detecting the length of a bellows, which adopts the following technical solution: A method for detecting the length of a corrugated pipe, using the drainage corrugated pipe extrusion manufacturing equipment to detect the length of the corrugated pipe, setting the movement direction of the pipe blank from the input end to the output end as the positive direction, including the processing steps: Feeding: The tube blank is pulled forward by the pulling mechanism; Cutting: Cut the corrugated tube by the cutting mechanism; Initialization of the tube blank origin: First, the tube blank is pulled in the reverse direction by the pulling mechanism, and the pulling mechanism stops moving. Then, the cut corrugated tube section is pulled in the reverse direction by the quality inspection mechanism. The corrugated tube section pushes back the tube blank on the pulling mechanism, so that the end position of the tube blank is flush with the output origin of the pulling mechanism, and at the same time, the cut surface of the corrugated tube section close to the tube blank is flush with the input origin of the quality inspection mechanism; Length measurement: the length of the corrugated pipe section placed inside is measured by a quality inspection agency; Sorting of good and bad products: Automatically screen out the corrugated pipe sections with qualified length and the corrugated pipe sections with unqualified length, and cut them separately.

[0022] By adopting the above technical scheme, the processing steps of feeding, cutting, initialization of the tube blank origin, length measurement and sorting of good and defective products are carried out in sequence to form an efficient and accurate bellows length detection mechanism. Compared with the prior art, the present application firstly pulls the tube blank forward by a traction mechanism, and then cuts the corrugated tube by a cutting mechanism to obtain a corrugated tube segment, and then cleverly utilizes the synergistic effect of the traction mechanism and the quality inspection mechanism to initialize the tube blank origin and the corrugated tube segment origin, so that each detection can start from a fixed reference point, thereby achieving the purpose of eliminating cumulative errors and avoiding inertial feeding, further enhancing the consistency of detection, and improving the accuracy of length detection. In addition, the realization of automated good and defective product sorting steps is conducive to improving the sorting efficiency of corrugated tube segments, while reducing misjudgment and mixing problems caused by human factors, which is conducive to improving product quality and the overall intelligence level of the production line.

[0023] Preferably, during the material feeding processing step, the separating mechanism simultaneously determines the initial position, and during the material cutting processing step, the pulling mechanism stops pulling the tube blank.

[0024] By adopting the above technical solution, the initial position of the cutting mechanism is determined simultaneously during the feeding process, which effectively saves production time and helps to improve the work efficiency of the production line. This parallel processing mode optimizes the production process and reduces unnecessary waiting and pauses. In the cutting step, the traction mechanism stops traction of the tube blank, which can ensure the stability and accuracy of the cutting operation, thereby reducing the cutting error caused by the movement of the tube blank and improving the processing accuracy of the corrugated pipe section.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. The upper guide wheel, the lower guide wheel and the elastic module cooperate to form an adjustable tube threading gap. At the same time, the tube threading gap size can be flexibly adjusted to adapt to tubes of different diameters or tubes of different diameters at the same time, providing continuous traction for the tubes, ensuring the stability and smoothness of the tubes during the traction process, and improving the versatility of the equipment; 2. Under the action of the cutting mechanism, the tube blank can be cut into corrugated tube segments. Automatic cutting greatly reduces the complexity and labor intensity of manual operation, achieving the purpose of improving production efficiency. Then, the corrugated tube segments are automatically clamped and length-tested by the quality inspection mechanism to ensure that the length of each corrugated tube segment is consistent. The online quality inspection method can timely discover and deal with unqualified products, which helps to improve the overall product quality level and improve the degree of product standardization; 3. The processing steps of feeding, cutting, initializing the origin of the tube blank, measuring the length and sorting out good and bad products are performed in sequence to form an efficient and accurate bellows length detection mechanism. Compared with the prior art, the present application firstly pulls the tube blank forward by a traction mechanism, and then cuts the corrugated tube by a cutting mechanism to obtain a corrugated tube segment. Then, the synergistic effect of the traction mechanism and the quality inspection mechanism is cleverly utilized to initialize the origin of the tube blank and the origin of the corrugated tube segment, so that each detection can start from a fixed reference point, thereby achieving the purpose of eliminating cumulative errors and avoiding inertial feeding, further enhancing the consistency of detection, and improving the accuracy of length detection. In addition, the realization of automated good and bad product sorting steps is conducive to improving the sorting efficiency of the corrugated tube segments, while reducing misjudgments and mixing problems caused by human factors, which is conducive to improving product quality and the overall intelligence level of the production line.

[0033] The following is combined with Figure 1-6 This application is described in further detail.

[0034] In a first aspect, an embodiment of the present application discloses a drainage corrugated pipe extrusion manufacturing device.

[0035] Reference Figure 1 and Figure 2A drainage corrugated pipe extrusion manufacturing equipment includes a frame 1, a feeding mechanism 2, a molding mechanism 3, a cooling mechanism 4, a traction mechanism 5, a breaking mechanism 6 and a quality inspection mechanism 7, wherein the feeding mechanism 2, the molding mechanism 3, the cooling mechanism 4, the traction mechanism 5, the breaking mechanism 6 and the quality inspection mechanism 7 are all arranged on the frame 1 and arranged in sequence, wherein the feeding mechanism 2 is arranged at the output end of the frame 1 for storing materials and automatically feeding; the molding mechanism 3 is fixed on the frame 1 and distributed at the output end of the feeding mechanism 2 for molding a tube blank 8; the cooling mechanism 4 is arranged at the output end of the feeding mechanism 2 for forming ... The cooling mechanism 4 is fixed on the frame 1 and distributed at the output end of the forming mechanism 3, and is used for cooling the tube blank 8 and providing output traction; the traction mechanism 5 is fixed on the frame 1 and distributed at the output end of the cooling mechanism 4, and is used for guiding the tube blank 8 and providing input traction; the cutting mechanism 6 is fixed on the frame 1 and distributed at the output end of the traction mechanism 5, and is used for cutting the tube blank 8 into corrugated pipe sections 9; the quality inspection mechanism 7 is fixed on the frame 1 and distributed at the output end of the cutting mechanism 6, and is used for clamping and length detection of the corrugated pipe section 9.

[0036] The present application, through the coordinated action of multiple mechanisms such as the feeding mechanism 2, the forming mechanism 3, the cooling mechanism 4, the traction mechanism 5, the breaking mechanism 6 and the quality inspection mechanism 7, can realize the production and manufacturing of the corrugated pipe segment 9, automatic quality inspection and screening of good and defective products, achieve the purpose of automated production, and improve production efficiency.

[0037] Specifically, refer to Figure 2 and Figure 3 The feeding mechanism 2 includes a feeding machine base 21, a storage module 22, a weighing module 23 and a feeding module 24, wherein the storage module 22, the weighing module 23 and the feeding module 24 are arranged from top to bottom and are all installed on the top of the feeding machine base 21. The storage module 22 provides storage space for materials. The weighing module 23 automatically weighs and limits the amount of materials entering the feeding module 24 each time. The output end of the feeding module 24 is connected to the output end of the forming mechanism 3. The feeding module 24 serves as a power source to continuously supply a certain amount of materials to the forming mechanism 3.

[0038] More specifically, the molding mechanism 3 includes a heating module 31 and a molding module 32, wherein the heating module 31 is used to heat the solid material into a molten material, and the molding module 32 molds the molten material into a tube blank 8. The molding module 32 includes two chain groups 321 and multiple mold units 322. The number of mold units 322 on the two chain groups 321 is consistent. The two chain groups 321 are arranged in parallel on the frame 1, and the two directions are opposite. At the same time, the shape structures of the two mold units 322 distributed opposite to each other are consistent. The chain group 321 has active energy to drive the mold units 322 installed thereon to rotate at the same time, and a space is left between the two chain groups 321 for the molten material to pass through.

[0039] When in use, the operator only needs to place the solid material in the storage module 22 of the feeding mechanism 2 for automatic storage, and the weighing module 23 automatically weighs and limits the amount of material entering the feeding module 24 each time. The feeding module 24, as a power source, continuously supplies a certain amount of material to the molding mechanism 3, making the production process more continuous and efficient, reducing the links of manual handling and adding materials, helping to reduce labor intensity and improve production efficiency. Then, the solid material can be quickly heated to a molten state through the heating module 31, and the molding module 32 is started, so that the two chain groups 321 operate at the same time, and the molten material can be forwardly transmitted. At the same time, under the action of different mold units 322, the pipe diameter can be formed into different pipe diameter sizes in different intervals. In this application, the model and shape structure of the feeding mechanism 2 and the molding mechanism 3 are not specifically limited. It is only necessary to realize the functions of automatic storage, feeding and molding of materials. Those skilled in the art can refer to the existing technology to realize the above functions.

[0040] Reference Figure 2 and Figure 3 In the present application, the cooling mechanism 4 includes a cooling base 41, a cooling module 42, and an output traction module 43. The cooling module 42 is used to cool the tube blank 8. The output traction module 43 is used to actively pull the tube blank 8 forward for transportation. The traction mechanism 5 is arranged at the output end of the cooling mechanism 4.

[0041] Specifically, the cooling module 42 includes a cooling channel 421 fixed on the top surface of the cooling base 41. The cooling channel 421 is provided with a cooling groove along its length direction, and cold air is continuously passed into the cooling groove. The output traction module 43 includes a traction wheel 431 rotatably arranged on the cooling base 41 near the output end of the cooling channel 421, and a traction motor (not shown in the figure) fixed on the cooling base 41, so that the output end of the traction motor is assembled with the traction wheel 431.

[0042] When in use, the tube blank 8 output by the forming mechanism 3 passes through the cooling groove and enters the output traction module 43. The cold air immediately cools the tube blank 8 just out of the mold, so that the tube blank 8 can be quickly formed and reach an ideal temperature state, reducing deformation or quality problems of the tube blank 8 caused by overheating. The traction motor serves as a power source to drive the traction wheel 431 to rotate, so that the cooled tube blank 8 can be smoothly and continuously transported to the next processing link, reducing the pause and waiting time in the production process, thereby improving the continuity and efficiency of the overall production process.

[0043] The present application places the traction mechanism 5 at the output end of the cooling mechanism 4. Such a layout can ensure that the tube blank 8 is pulled after being fully cooled, thereby reducing the risk of stress concentration or fracture of the tube blank 8 due to temperature differences, and can also ensure the compactness and efficiency of the entire production line.

[0044] Reference Figure 3 and Figure 4 An input traction module 44 is provided at a position of the frame 1 near the traction mechanism 5. The structure of the input traction module 44 is consistent with that of the output traction module 43, and is used to provide positioning and guidance for the tube blank 8 before it enters the traction mechanism 5. The structure of the input traction module 44 will not be repeated here.

[0045] In the present application, before the tube blank 8 enters the traction mechanism 5, the input traction module 44 can provide accurate positioning and guiding for the tube blank 8, so that the tube blank 8 can enter the traction mechanism 5 in the correct position and state, effectively reducing the problems of equipment jamming or damage caused by improper entry of the tube blank 8, which helps to improve the continuity and efficiency of the production process.

[0046] Reference Figure 5 and Figure 6 The traction mechanism 5 includes an upper guide wheel 51 and a lower guide wheel 52. The upper guide wheel 51 and the lower guide wheel 52 are arranged opposite to each other up and down, and a pipe-threading gap is left between the two. An elastic module 53 is arranged between the upper guide wheel 51 and the lower guide wheel 52. The elastic module 53 is used to adjust the pipe-threading gap between the upper guide wheel 51 and the lower guide wheel 52. The tube blank 8 passes through the tube-threading gap. The upper guide wheel 51 and the lower guide wheel 52 cooperate to actively pull the tube blank 8 forward for transportation.

[0047] In the present application, an adjustable tube threading gap is formed by the cooperation of the upper guide wheel 51, the lower guide wheel 52 and the elastic module 53, and the size of the tube threading gap can be flexibly adjusted to adapt to tube blanks 8 of different diameters or tube blanks 8 of different diameters at the same time, providing continuous traction for the tube blank 8, ensuring the stability and smoothness of the tube blank 8 during the traction process, and improving the versatility of the equipment.

[0048] Specifically, the elastic module 53 includes a power component 532 and an elastic component 531, wherein the power component 532 has two and the elastic component 531 has one, wherein the power component 532 includes a first connecting shaft 5321, a driving gear 5322, a second connecting shaft 5323, a driven gear 5324, a power piece 5325 and a pendulum block 5326. In the present application, the first connecting shaft 5321 is rotatably connected to the side wall of the frame 1, the driving gear 5322 is assembled on the outer wall of the first connecting shaft 5321, the pendulum block 5326 is bearing-connected to the outer wall of the first connecting shaft 5321, and the second connecting shaft 5323 is also bearing-connected. The upper guide wheel 51 is mounted on the second connecting shaft 5323 of a power component 532, and the upper guide wheel 51 is arranged at one end of the second connecting shaft 5323 away from the side wall of the frame 1. The power piece 5325 is mounted on the end of the first connecting shaft 5321, and the power piece 5325 serves as a power source to drive the first connecting shaft 5321 to rotate.

[0049] More specifically, the lower guide wheel 52 is assembled at the end of another second connecting shaft 5323, so that the upper guide wheel 51 and the lower guide wheel 52 are distributed vertically opposite each other, and the elastic component 531 includes a buffer 5311 connected between the two pendulum blocks 5326. The buffer 5311 can be an elastic rubber rope or spring, which ensures that one end of the buffer 5311 is connected to the upper pendulum block 5326 and the other end is connected to the lower pendulum block 5326. At this time, the buffer 5311 plays the role of shock absorption, buffering and linkage, and can realize flexible control of the pipe threading gap, while effectively reducing the vibration and noise of the equipment during operation, improving the working stability and reliability of the equipment, and protecting the pendulum block 5326 and connected components from impact damage, thereby helping to extend the service life of the equipment.

[0050] In order to better realize the synchronous operation of the upper guide wheel 51 and the lower guide wheel 52, and provide traction for the tube blank 8 set in the tube threading gap, two preferred implementation methods are provided in the present application to link the upper guide wheel 51 and the lower guide wheel 52. The first is to mesh the driving gears 5322 of the two sets of power components 532. In this way, the upper guide wheel 51 and the lower guide wheel 52 can be synchronously driven to rotate by a power member 5325. The second is to drive the upper guide wheel 51 and the lower guide wheel 52 respectively by two power members 5325, so that both can provide traction for the tube blank 8 set in the tube threading gap. In the present application, it is preferred to drive the upper guide wheel 51 and the lower guide wheel 52 to rotate by a power member 5325 to ensure the synchronous rotation of the upper guide wheel 51 and the lower guide wheel 52, so that the tube blank 8 can be stably transmitted.

[0051] In the present application, the specific structure of the power component 5325 is not specifically limited. It only needs to be able to provide a variable speed rotating power source for the first connecting shaft 5321. Here, a preferred and simple-structured power component 5325 is provided. When there is only one group of guide wheel groups consisting of an upper guide wheel 51 and a lower guide wheel 52, the power component 5325 selects a variable speed motor; when there are several groups of guide wheel groups consisting of an upper guide wheel 51 and a lower guide wheel 52, in order to achieve the synchronization function, the power component 5325 includes a variable speed motor, a synchronous pulley and a transmission belt, so that one synchronous pulley is correspondingly assembled on one of the first connecting shafts 5321, and the transmission belt is engaged with all the synchronous pulleys at the same time, and the output end of the variable speed motor is assembled with the end of one of the first connecting shafts 5321.

[0052] When in use, the power member 5325 is started to drive the first connecting shaft 5321 to rotate, and the first connecting shaft 5321 drives the driving gear 5322 to rotate, thereby driving the driven gear 5324 and the second connecting shaft 5323 to rotate. Since the pendulum block 5326 and the second connecting shaft 5323, and the pendulum block 5326 and the first connecting shaft 5321 are fixed by bearing connection, the pendulum block 5326 can swing to a certain extent, and the buffer member 5311 connected between the two pendulum blocks 5326 plays a role in shock absorption and buffering. and linkage, so that both the upper guide wheel 51 and the lower guide wheel 52 have the ability to rotate and adjust their positions at the same time, so as to adjust the distance between the upper guide wheel 51 and the lower guide wheel 52, and achieve the purpose of flexibly controlling the pipe threading gap, so that it can adapt to pipe blanks 8 of different diameters or pipe blanks 8 of different pipe diameters at the same time, provide continuous traction for the pipe blank 8, ensure the stability and smoothness of the pipe blank 8 during the traction process, improve the versatility of the equipment, effectively reduce the vibration and noise of the equipment during operation, and improve the working stability and reliability of the equipment.

[0053] Reference Figure 5 and Figure 6In order to further improve the stability of the tube blank 8 conveying process, the device also includes an elastic module 54, which is fixedly arranged on the frame 1 and distributed at a position of the frame 1 close to the traction mechanism 5, wherein the elastic module 53 includes a fixed seat 541, a guide rod 542, a matching block 543, a buffer spring 544, an upper rotating wheel 545 and a lower rotating wheel 546, wherein the fixed seat 541 is fixedly installed on the top surface of the frame 1, and the guide rod 542 has at least one and is vertically arranged. Installed on the top surface of the fixed seat 541, the matching block 543 is slidably connected to the guide rod 542, the buffer spring 544 is sleeved on the outer wall of the guide rod 542 and distributed between the fixed seat 541 and the matching block 543, the upper rotating wheel 545 is rotatably connected to the side wall of the fixed seat 541, and the lower rotating wheel 546 is rotatably connected to the side wall of the matching block 543, so that the upper rotating wheel 545 and the lower rotating wheel 546 are distributed vertically opposite to each other, and a tube supply gap is left between the two, and the tube blank 8 passes through the tube supply gap.

[0054] When in use, under the joint action of the fixed seat 541, the guide rod 542, the matching block 543 and the buffer spring 544, an efficient elastic module 54 is formed, so that the upper rotating wheel 545 and the lower rotating wheel 546 are distributed opposite each other and the relative position of the two is guaranteed to be stable. In addition, the buffer spring 544 provides an elastic adjustment function for the pipe supply gap between the two. When the tube blank 8 passes through the pipe supply gap, the buffer spring 544 can be adaptively adjusted according to the diameter change of the tube blank 8 to ensure that the pipe supply gap is always maintained in the optimal state, effectively reducing the jamming or damage problems caused by uneven or changing diameters of the tube blank 8, and helping to improve the smoothness of the production process and the stability of product quality.

[0055] The present application ensures that the upper rotating wheel 545 and the lower rotating wheel 546 can rotate flexibly when pulling the tube blank 8, thereby reducing friction resistance and improving pulling efficiency. At the same time, the flexible traction provided by the pulling mechanism 5 can optimize the stress state of the tube blank 8, making the pulling process more stable and reliable.

[0056] Reference Figure 5 and Figure 6 The quality inspection mechanism 7 includes a rodless cylinder 71, a slider 72, a segment rod 73, and a distance sensor 74, wherein the segment rod 73 is provided with a hollow groove along its length direction, and the tube blank 8 passes through the hollow groove. The bottom of the slider 72 is assembled with the output end of the rodless cylinder 71, the segment rod 73 is assembled on the top of the slider 72, and the distance sensor 74 is fixed on the frame 1 for calculating the movement stroke of the slider 72.

[0057] The rodless cylinder 71, slider 72, segmenting rod 73 and distance sensor 74 are integrated to construct an accurate and efficient quality inspection system. The tube blank 8 can pass through the hollow groove on the segmenting rod 73 without obstacles, ensuring the stable position of the tube blank 8 during the inspection process. At the same time, the segmenting rod 73 is used as a reference point for inspection. With the cooperation of the rodless cylinder 71 and the slider 72, the segmenting rod 73 can be moved smoothly and controllably. The distance sensor 74 accurately calculates the movement stroke of the slider 72, which can achieve high-precision measurement of the length of the tube blank 8. The entire quality inspection process has a high degree of automation, reducing human intervention and errors.

[0058] In addition, the cutting mechanism 6 is arranged between the quality inspection mechanism 7 and the traction mechanism 5, and can cut the tube blank 8 transported by the traction mechanism 5. The cutting mechanism 6 includes a mounting seat 61, a cutter 62, a limit seat 63, and a driving assembly 64, wherein there are two cutters 62, a gap is left between the two cutters 62, the cutter 62 is fixedly mounted on the side wall of the mounting seat 61, the output end of the driving assembly 64 is assembled with the mounting seat 61, and the driving assembly 64 acts as a power source to drive the cutter 62 to move, the limit seat 63 and the mounting seat 61 are both fixed on the top surface of the frame 1, and the two are respectively arranged on the left and right sides of the tube blank 8, and the tube blank 8 can pass between the limit seat 63 and the mounting seat 61, and two limit bayonets are arranged on the side of the limit seat 63 close to the cutter 62, so that the limit bayonet is directly opposite to the cutter 62 close to it.

[0059] In the present application, the specific structure of the driving assembly 64 is not specifically limited, but it is required to have the ability to start quickly and drive the cutter 62 to cut the tube blank 8. Those skilled in the art can refer to the existing technology to achieve the above functions.

[0060] Under the action of the cutting mechanism 6, the tube blank 8 is cut into corrugated pipe segments 9, and the end faces of the tube blank 8 and the corrugated pipe segments 9 are cut flush to ensure the production quality of the corrugated pipe segments 9. In the present application, the automated cutting greatly reduces the complexity and labor intensity of manual operation, thereby achieving the purpose of improving production efficiency. The corrugated pipe segments 9 are then automatically clamped and length-detected by the quality inspection mechanism 7 to ensure that the length of each corrugated pipe segment 9 is consistent. The online quality inspection method can promptly detect and handle unqualified products, which helps to improve the overall product quality level and the degree of product standardization.

[0061] In a second aspect, an embodiment of the present application discloses a method for detecting the length of a corrugated pipe, using a drainage corrugated pipe extrusion manufacturing device to detect the length of the corrugated pipe.

[0062] Reference Figure 1-6 A method for detecting the length of a corrugated tube, setting the moving direction of the tube blank 8 from the input end to the output end as the positive direction, includes the following processing steps: Feeding: The tube blank 8 is pulled forward by the pulling mechanism 5.

[0063] Specifically, the operator places the solid material in the storage module 22 of the feeding mechanism 2 for automatic storage, and the weighing module 23 automatically weighs and limits the amount of material entering the feeding module 24 each time. The feeding module 24, as a power source, continuously supplies a fixed amount of material to the forming mechanism 3, and then the solid material can be quickly heated to a molten state through the heating module 31, and the forming module 32 is started, so that the two chain groups 321 operate at the same time, and the molten material can be forwardly transmitted. At the same time, under the action of different mold units 322, the pipe diameter can be formed into different pipe diameter sizes in different intervals. The tube blank 8 output by the forming mechanism 3 passes through the cooling groove and enters the output traction module 43. The cold air immediately cools the tube blank 8 just out of the mold. The traction motor, as a power source, drives the traction wheel 431 to rotate, so that the cooled tube blank 8 can be smoothly and continuously transported to the input traction module 44. The input traction module 44 provides accurate positioning and guiding for the tube blank 8, so that the tube blank 8 can enter the traction mechanism 5 in the correct position and state. Start the power piece 5325 to drive the first connecting shaft 5321 to rotate. The first connecting shaft 5321 drives the driving gear 5322 to rotate, thereby driving the driven gear 5324 and the second connecting shaft 5323 to rotate. The upper guide wheel 51 and the lower guide wheel 52 rotate, and provide positive traction for the tube blank 8. At the same time, with the cooperation of the pendulum block 5326 and the buffer 5311, the upper guide wheel 51 and the lower guide wheel 52 can adapt to tube blanks 8 of different diameters or tube blanks 8 of different diameters at the same time, provide continuous traction for the tube blank 8, and then transport the tube blank 8 to the breaking mechanism 6.

[0064] Cutting: The corrugated tube is cut by the cutting mechanism 6.

[0065] During the feeding process, the initial position of the cutting mechanism 6 is determined at the same time, that is, the cutting mechanism 6 is moved closer to the center line of the tube blank 8 to prepare for cutting at any time, thereby effectively saving production time, helping to improve the work efficiency of the production line, and reducing unnecessary waiting and pauses. When the cutting process is performed, the traction mechanism 5 stops traction of the tube blank 8 to ensure the stability and accuracy of the cutting operation, thereby reducing the cutting error caused by the movement of the tube blank 8 and improving the processing accuracy of the corrugated pipe section 9.

[0066] Initialization of the origin of the tube blank 8: first, the tube blank 8 is pulled in reverse by the traction mechanism 5, and then the cut corrugated tube section 9 is pulled in reverse by the quality inspection mechanism 7. The corrugated tube section 9 pushes back the tube blank 8 on the traction mechanism 5, so that the end position of the tube blank 8 is flush with the output origin of the traction mechanism 5, and at the same time, the cut surface of the corrugated tube section 9 close to the tube blank 8 is flush with the input origin of the quality inspection mechanism 7.

[0067] Specifically, the power member 5325 is started to drive the first connecting shaft 5321 to rotate, and the first connecting shaft 5321 drives the driving gear 5322 to rotate, thereby driving the driven gear 5324 and the second connecting shaft 5323 to rotate, and the upper guide wheel 51 and the lower guide wheel 52 rotate, and provide reverse traction force for the tube blank 8, so that the end position of the tube blank 8 tends to and infinitely approaches the position flush with the output origin of the traction mechanism 5. The power member 5325 stops moving, and then the rodless cylinder 71 is started, and the slider 72 drives the corrugated tube section 9 inserted in the hollow groove of the fixed section rod 73, and the corrugated tube section 9 pushes back the tube blank 8 on the traction mechanism 5 in the reverse direction until the end position of the tube blank 8 is flush with the output origin of the traction mechanism 5, and at the same time, the cut surface of the corrugated tube section 9 close to the tube blank 8 is flush with the input origin of the quality inspection mechanism 7.

[0068] Length measurement: The quality inspection mechanism 7 is used to detect the length of the corrugated tube section 9 placed inside it.

[0069] Specifically, the rodless cylinder 71 is started, and the slider 72 drives the corrugated tube segment 9 inserted in the hollow groove of the fixed segment rod 73 to move forward, and the distance sensor 74 identifies the movement distance of the slider 72. At this time, the length of the hollow groove inside the fixed segment rod 73 is consistent with the length of the standard length of the corrugated tube segment 9, that is, the sliding distance of the slider 72, thereby realizing the length detection of the corrugated tube segment 9.

[0070] Sorting of good and bad products: automatically screen out the corrugated pipe sections 9 with qualified length and the corrugated pipe sections 9 with unqualified length, and cut them separately.

[0071] In the present application, the processing steps of feeding, cutting, initialization of the origin of the tube blank 8, length measurement and sorting of good and bad products are performed in sequence to form an efficient and accurate bellows length detection mechanism. Compared with the prior art, the present application firstly pulls the tube blank 8 in a positive direction through the traction mechanism 5, and then cuts the corrugated tube through the cutting mechanism 6 to obtain the corrugated tube segment 9. Then, the synergistic effect of the traction mechanism 5 and the quality inspection mechanism 7 is cleverly utilized to initialize the origin of the tube blank 8 and the origin of the corrugated tube segment 9, so that each detection can start from a fixed reference point, thereby achieving the purpose of eliminating cumulative errors and avoiding inertial feeding, further enhancing the consistency of detection, and improving the accuracy of length detection. In addition, the realization of automated good and bad product sorting steps is conducive to improving the sorting efficiency of the corrugated tube segment 9, while reducing misjudgment and mixing problems caused by human factors, which is conducive to improving product quality and the overall intelligence level of the production line.

[0072] The above are all preferred embodiments of the present application. The embodiments are only explanations of the present application and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
