Description

Technical Field

[0001] The invention relates to the technical field of water conveyor belt processing equipment, and in particular to a water conveyor belt forming equipment prefabricated with an external pipe joint. Background Art

[0002] Water conveyor belts are important tools for conveying water. They are usually made of plastic or rubber materials and have good corrosion resistance and flexibility. Since water conveyor belts need to be connected to external pipelines or water conveyance facilities, external pipe joints are usually required on the water conveyor belts. Among them, prefabricated water conveyor belts that have pipe joints externally embedded in the water conveyor belts in the factory are widely used in agricultural irrigation, municipal water supply, water conservancy projects and other fields due to their low cost and stable quality.

[0003] To install a pipe joint on a water conveying belt, first, it is necessary to process the installation hole on the water conveying belt, and then weld the pipe joint to the installation hole. The invention patent with the Chinese application publication number CN116100630A discloses a processing device for a water conveying belt with an external pipe joint, which realizes a manufacturing process that can directly process the installation hole on the tubular finished water conveying belt and weld the pipe joint to the installation hole, breaking the technical barrier that the original manufacturing process can only process the installation hole and weld the pipe joint on the long strip blank, reducing the limitation of the blank requirements, reducing the production cost, and the tubular water conveying belt has better structural performance, will not cause leakage, and improves the product quality. On this basis, how to further improve production efficiency and improve product quality is a new technical difficulty faced by technical personnel in this field. Summary of the invention

[0004] The present invention provides a forming device for a prefabricated water conveying belt with an externally-mounted pipe joint, so as to further improve the production efficiency of the water conveying belt with an externally-mounted pipe joint and improve the product quality.

[0005] To achieve the above-mentioned purpose and other related purposes, the present invention provides a prefabricated water conveyor belt forming equipment with an external pipe joint, which is used to process installation holes for the water conveyor belt and fix the pipe joint externally on the installation hole. The prefabricated water conveyor belt forming equipment with an external pipe joint includes: an assembly line workbench, a hole-opening device and a feeding and fixing coordination device; the assembly line workbench includes a plurality of workstations, the water conveyor belt moves on the assembly line workbench, and performs corresponding processing when it moves to a preset workstation; the hole-opening device is movably arranged on the assembly line workbench, and is used to process installation holes for the water conveyor belt; along the moving direction of the water conveyor belt, the feeding and fixing coordination device is arranged downstream of the hole-opening device, and the feeding and fixing coordination device includes a feeding mechanism and a fixing mechanism, the feeding mechanism is arranged on one side of the assembly line workbench, and is used to convey the pipe joint to the bottom of the fixing mechanism, and the fixing mechanism is arranged on the assembly line workbench, and is used to fix the pipe joint to the installation hole.

[0006] In the above technical scheme, the process of processing the installation hole for the water conveying belt by the hole-punching device and the processing process of the feeding and fixing cooperative device are located at different workstations, and the feeding mechanism of the feeding and fixing cooperative device directly transports the pipe joint to the bottom of the fixing mechanism, and then fixes the pipe joint to the installation hole through the fixing mechanism. The external pipe joint prefabricated water conveying belt forming equipment realizes that the processing of the installation hole of the water conveying belt, the loading of the pipe joint and the fixing of the pipe joint can be carried out simultaneously. Specifically, during the movement of the water conveying belt, the feeding mechanism completes the transportation of the pipe joint to the bottom of the fixing mechanism. When the water conveying belt stops, the hole-punching device processes the installation hole and the fixing mechanism fixes the pipe joint simultaneously. Compared with the prior art, the time of the processing process of the external pipe joint includes the sum of the working time of processing the installation hole of the water conveying belt, loading the pipe joint, fixing the pipe joint and moving the water conveying belt. The time of completing the external pipe joint in this technical scheme is shortened to only the working time of moving the water conveying belt and fixing the pipe joint, which optimizes the process of the assembly line processing of the external pipe joint, shortens the processing time, and improves the processing efficiency and product quality.

[0007] In an example of a prefabricated water conveyor belt forming device for an externally embedded pipe joint of the present invention, the assembly line workbench includes a work surface, a guide limiting mechanism, a main drive wheel, a main drive wheel clamping mechanism, a passive wheel, a passive wheel clamping mechanism, a displacement detection mechanism and a fixture; the guide limiting mechanism is arranged on both sides of the work surface; the main drive wheel is located at the end of the work surface where the water conveyor belt leaves; the main drive wheel clamping mechanism is located on the side of the main drive wheel away from the work surface; the passive wheel is located at the end of the work surface where the water conveyor belt enters; the passive wheel clamping mechanism is located on the side of the passive wheel away from the work surface; the displacement detection is arranged on the work surface; the fixture is arranged on the work surface and is located below the feeding and fixing coordination device; wherein, the main drive wheel clamping mechanism and the passive wheel clamping mechanism press the water conveyor belt onto the main drive wheel and the passive wheel, and the fixture positions and clamps the water conveyor belt during the processing.

[0008] In the above technical scheme, the guide and limiting mechanism improves the straightness of the moving trajectory of the water conveying belt and ensures the accuracy of the position of the installation hole. The main transmission wheel provides the power for the movement of the water conveying belt. The coordinated action of the main transmission wheel, the main transmission wheel clamping mechanism, the passive wheel and the passive wheel clamping mechanism realizes the movement of the water conveying belt on the work surface. The displacement detection mechanism realizes the detection of the moving step of the water conveying belt and feeds back to the electrical control system and other components, which is conducive to the automatic control of the equipment; the tooling fixture realizes the positioning and clamping of the water conveying belt, overcomes the technical difficulties of single-sided processing of installation holes on the tubular finished water conveying belt and externally inlaying pipe joints, improves the accuracy of processing installation holes, loading and fixing, and improves production quality.

[0009] In an example of a prefabricated water conveyor belt forming device for an external pipe joint of the present invention, the hole opening device includes a mounting seat, a Y-axis moving mechanism and two hole opening knives; the Y-axis moving mechanism is slidably installed on the mounting seat, and the sliding direction of the Y-axis moving mechanism is horizontally perpendicular to the moving direction of the water conveyor belt; the two hole opening knives are respectively arranged at both ends of the Y-axis moving mechanism.

[0010] In the above technical scheme, the two hole punching cutters respectively arranged at the two ends of the moving mechanism realize movement along the Y-axis under the drive of the Y-axis moving mechanism. This arrangement can realize that the two hole punching cutters can continuously perform installation hole processing. When one of the hole punching cutters is processing the installation hole, the other hole punching cutter avoids it and takes away the waste water conveying belt cut at the same time. After one of the hole punching cutters completes the processing, it moves away from the processing position and takes away the waste water conveying belt cut. At the same time, the other hole punching cutter moves to the processing position to process the installation hole. The continuous reciprocating operation is carried out to achieve the effect of improving the efficiency of processing the installation hole.

[0011] In an example of a prefabricated water conveyor belt forming device for an external pipe joint of the present invention, the fixing mechanism includes a column, a Z-axis moving mechanism and a welding head; the Z-axis moving mechanism is slidably installed on the column, and the moving direction of the Z-axis moving mechanism is vertically perpendicular to the assembly line workbench; the welding head is installed at one end of the Z-axis moving mechanism close to the assembly line workbench.

[0012] In the above technical scheme, the fixing mechanism is used to weld and fix the water conveyor belt and the pipe joint together. A relatively mature welding head is used, which is conducive to firmly sealing and fixing the pipe joint on the water conveyor belt, improving the sealing performance, and is conducive to improving product quality and ensuring the processing quality of the fixed pipe joint; in addition, the welding head can also move up and down along the column, thereby realizing intermittent installation and fixation of the pipe joint, which is conducive to the automatic processing of coordinating feeding and fixation.

[0013] In an example of a prefabricated water conveyor belt forming device for an externally embedded pipe joint of the present invention, the feeding mechanism includes a pipe joint conveying mechanism and a pipe joint positioning assembly; the pipe joint positioning assembly includes a positioning frame and a position detection sensor; the positioning frame is suspended and fixedly installed on the assembly line workbench, the incoming direction of the pipe joint conveying mechanism is aligned with one side of the positioning frame, and a positioning groove corresponding to the outer periphery of the pipe joint is provided on the side of the positioning frame facing the pipe joint conveying mechanism, and the positioning groove is used to limit the pipe joint to be located directly below the welding head; the position detection sensor is installed on the positioning frame, and is used to detect the position of the pipe joint to be processed.

[0014] In the above technical solution, the pipe joint positioning assembly is used to position the delivered pipe joint, the positioning groove is used to limit the pipe joint to be located directly below the welding head, so as to facilitate the accurate installation of the pipe joints on the water conveying belt in sequence, and the position detection sensor is used to detect whether the pipe joint has reached directly below the welding head, and can feedback the signal to the electrical control system, thereby realizing automatic positioning installation, improving the installation speed, and at the same time improving the installation accuracy, which is beneficial to improving the product production quality.

[0015] In an example of a prefabricated water conveying belt forming device with an external pipe joint of the present invention, the feeding and fixing coordination device also includes a pipe joint support assembly movably mounted on a positioning frame, the pipe joint support assembly has a first position and a second position, the pipe joint support assembly supports the pipe joint when it is in the first position, and avoids the pipe joint when it is in the second position.

[0016] In the above technical solution, the pipe joint support assembly is used to support the column pipe joint when the pipe joint is transported to the preset position. On the other hand, when the welding head is falling to weld the pipe joint, the pipe joint support assembly can avoid the way at the same time, so that the pipe joint can fall into the processed installation hole under the combined action of its own weight and the welding head, thereby realizing simultaneous loading and fixing processing.

[0017] In an example of a prefabricated water conveying belt forming device with an external pipe joint of the present invention, the pipe joint support assembly includes two openable and closable support plates, two driving members for driving the support plates to open and close, and two return springs; the two support plates are respectively connected to the opposite side edges of the positioning groove in a flippable manner; the two driving members are installed on the fixing mechanism, and can contact and move away from the support plates as the fixing mechanism moves; the two return springs are respectively arranged between the two support plates and the two side edges of the positioning groove to drive the support plates to reset when the driving members move away from the support plates.

[0018] In the above technical solution, two openable and closable support plates and a driving member for driving the support plates to open and close are used to drive the pipe joint to support and avoid the pipe joint by means of a mechanical structure, and the support plate is reset by a reset spring. This setting has a simple structure and reliable control, which is conducive to subsequent welding operations and improves the efficiency of automated processing.

[0019] In an example of a prefabricated water conveying belt forming device with an external pipe joint of the present invention, the feeding and fixing cooperative device also includes a floating plate assembly, the floating plate assembly includes a mounting plate, a plurality of first guide rods and a plurality of second guide rods; the plurality of first guide rods are fixed on the side of the mounting plate away from the work surface, and each first guide rod is sleeved with a first spring; each first guide rod is slidably connected with a pressure plate, the pressure plate is directly or indirectly mounted on the welding head, and moves with the movement of the welding head; a plurality of second guide rods are slidably mounted on the mounting plate, the second guide rods include a limiting portion located above the mounting plate and a guide rod portion slidably connected to the mounting plate, a second spring is sleeved on the outside of the second guide rod, and the second spring is located between the mounting plate and the positioning frame; two driving members are mounted on the mounting plate, and are respectively located above the two support plates.

[0020] In the above technical solution, when the welding head moves downward along the Z direction, the pressure plate installed on the welding head also moves downward, and acts on the mounting plate through the first spring, pushing the mounting plate downward, the second spring is compressed, and the driving member acts on the support plate at the same time. After the welding head completes welding, when it moves upward along the Z direction, the mounting plate also moves upward under the reset elastic force of the second spring and resets to the initial position. This setting facilitates the reasonable planning of the distance between the welding head, pipe joint, conveyor belt, support plate and driving member, so as to avoid interference between individual components and affect the welding quality.

[0021] In an example of a prefabricated water conveying belt forming equipment with external pipe joints of the present invention, the feeding and fixing coordination device also includes a pipe joint separation mechanism, which is installed on the side of the mounting plate facing the pipe joint to be transported, and the pipe joint separation mechanism is configured to be able to move with the mounting plate and separate the next adjacent pipe joint from the pipe joint being fixed when fixing the processed pipe joint.

[0022] In the above technical solution, the pipe joint separation component separates the pipe joints that are continuously arranged and transported, thereby preventing the adjacent pipe joints from overlapping, causing welding accidents and reducing the yield rate of pipe joint welding.

[0023] In an example of a prefabricated water conveyor belt forming device with an external pipe joint of the present invention, the feeding and fixing coordination device also includes an installation hole displacement detection device, which is installed on the work table and is located between the hole opening device and the fixing mechanism, and is used to detect the positioning of the installation holes on the water conveyor belt.

[0024] In the above technical solution, the mounting hole displacement detection device detects the displacement of the mounting hole and compares the measured value with the preset value to determine whether the mounting hole is aligned with the welding head, thereby preventing the problem of welding deviation due to misalignment, thereby reducing the risk of welding deviation in the entire roll of conveyor belt.

[0025] In summary, the present invention has the following beneficial technical effects: 1. The process of processing the installation hole for the water conveying belt by the hole-punching device and the processing process of the feeding and fixing coordination device are located at different workstations, and the feeding mechanism of the feeding and fixing coordination device directly transports the pipe joint to the bottom of the fixing mechanism, and then fixes the pipe joint to the installation hole through the fixing mechanism. The external pipe joint prefabricated water conveying belt forming equipment realizes that the processing of the installation hole of the water conveying belt, the loading of the pipe joint and the fixing of the pipe joint can be carried out at the same time. Specifically, during the movement of the water conveying belt, the feeding mechanism completes the transportation of the pipe joint to the bottom of the fixing mechanism. When the water conveying belt stops, the hole-punching device processes the installation hole and the fixing mechanism fixes the pipe joint at the same time. Compared with the prior art, the time of the processing process of the external pipe joint includes the sum of the working time of processing the installation hole of the water conveying belt, loading the pipe joint, fixing the pipe joint and moving the water conveying belt. The time of completing the external pipe joint in this technical solution is shortened to only the working time of moving the water conveying belt and fixing the pipe joint, which optimizes the process of the assembly line processing of the external pipe joint, shortens the processing time, and improves the processing efficiency and product quality.

[0026] 2. The guide limit mechanism improves the straightness of the moving trajectory of the water conveying belt and ensures the accuracy of the position of the installation hole. The main drive wheel provides the power for the water conveying belt to move. The coordinated action of the main drive wheel, the main drive wheel clamping mechanism, the passive wheel and the passive wheel clamping mechanism realizes the movement of the water conveying belt on the work surface. The displacement detection mechanism detects the moving step of the water conveying belt and feeds back to the electrical control system and other components, which is conducive to the automatic control of this equipment; the tooling fixture realizes the positioning and clamping of the water conveying belt, overcomes the technical difficulties of single-sided processing of installation holes on the tubular finished water conveying belt and externally inlaying pipe joints, improves the accuracy of processing installation holes, loading and fixing, and improves production quality.

[0027] 3. The two hole punching cutters respectively arranged at the two ends of the moving mechanism realize movement along the Y-axis under the drive of the Y-axis moving mechanism. This setting can realize that the two hole punching cutters can continuously process the installation holes. When one of them processes the installation hole, the other one avoids it and takes away the waste water conveying belt cut off at the same time, so as to improve the efficiency of processing the installation hole.

[0028] 4. The fixing mechanism is used to fix the water conveying belt and the pipe joint together. The relatively mature welding head is used, which is conducive to firmly sealing and fixing the pipe joint on the water conveying belt, improving the sealing performance, and is conducive to improving product quality and ensuring the processing quality of the fixed pipe joint. In addition, the welding head can also move up and down along the column, thereby realizing intermittent installation and fixation of the pipe joint, which is conducive to the automatic processing of coordinating feeding and fixation.

[0029] 5. The pipe joint positioning assembly is used to position the pipe joints delivered. The positioning groove is used to limit the pipe joints to be located directly below the welding head, which is convenient for accurately installing the pipe joints on the water conveying belt in sequence. The position detection sensor is used to detect whether the pipe joints have reached directly below the welding head and can feedback signals to the control system, realizing automatic positioning installation, improving installation speed, and at the same time improving installation accuracy, which is beneficial to improving product production quality.

[0051] See also Figures 7 to 9In an example of a prefabricated water conveying belt forming device with an external pipe joint of the present invention, the feeding and fixing coordination device 5 also includes a pipe joint support assembly 53 movably mounted on the positioning frame 5121.

At this time, the pipe joint 2 is transported to the preset position, that is, it is located directly below the welding head 523 and waits for welding. When the pipe joint support assembly 53 is in the second position, it avoids the pipe joint 2, that is, when the welding head 523 falls to weld the pipe joint 2, the pipe joint support assembly 53 can avoid it at the same time, so that the pipe joint 2 falls into the processed installation hole under the joint action of its own weight and the welding head 523, and realizes simultaneous feeding and fixing processing. It should be noted that there are many structural forms for realizing the avoidance of the pipe joint support assembly 53, such as automatic flipping opening and closing, push-pull opening and closing, folding opening and closing, or winding opening and closing, etc., which are not limited to this.

[0052] See also Figures 7 to 9 In an example of a prefabricated water conveying belt forming device for an external pipe joint of the present invention, the pipe joint support assembly 53 includes two openable and closable support plates 531, two driving members 532 for driving the support plates 531 to open and close, and two return springs 533; the two support plates 531 are respectively and flipably connected to the two opposite sides of the positioning groove 51211; the two driving members 532 are installed on the fixing mechanism 52, and can contact the support plates 531 and move away from the support plates 531 as the fixing mechanism 52 moves; the two return springs 533 are respectively arranged between the two support plates 531 and the two sides of the positioning groove 51211 to drive the support plates 531 to return to their original positions when the driving members 532 move away from the support plates 531.

Joint 523, and moves with the movement of the welding head 523; multiple second guide rods 543 are slidably installed on the mounting plate 541, the second guide rods 543 include a limiting portion 547 located above the mounting plate 541 and a guide rod portion 548 slidably connected to the mounting plate 541, the second guide rods 543 are sheathed with a second spring 545, and the second spring 545 is located between the mounting plate 541 and the positioning frame 5121; two driving members 532 are installed on the mounting plate 541, and are respectively located above the two support plates 531.

[0054] See also Figures 7 to 9 In this embodiment, when the welding head 523 moves downward along the Z direction, the pressing plate 546 installed on the welding head 523 also moves downward, and acts on the mounting plate 541 through the first spring 544, pushing the mounting plate 541 downward, and the second spring 545 is compressed, and at the same time, the driving member 532 acts on the support plate 531, so that the support plate 531 flips downward to avoid the pipe joint 2. The pipe joint 2 falls into the mounting hole under the combined action of its own weight and the welding head 523, and the welding head 523 continues to move downward until the pipe joint 2 and the water conveying belt 1 are welded and fixed. After the welding head 523 completes welding, when it moves upward along the Z direction, the mounting plate 541 also moves upward under the reset elastic force of the second spring 545 and resets to the initial position. This setting facilitates the reasonable planning of the distance between the welding head 523, the pipe joint 2, the conveyor belt, the support plate 531 and the driving member 532, so as to prevent interference between the individual components and affect the welding quality.

The setting of the pipe joint 2 separation component realizes the separation of the pipe joints 2 that are continuously arranged and transported, and prevents the overlapping of the adjacent pipe joints 2 that are transported, resulting in welding accidents and reducing the yield rate of the pipe joint 2 welding.

After the preset length, the mounting hole just runs to be coaxial with the welding head 523. Preferably, the mounting hole displacement detection device 56 is located between the displacement detection mechanism 38 and the welding head 523. The value detected by the mounting hole displacement detection device 56 can be compared with the running distance set by the displacement detection mechanism 38 to determine whether the mounting hole is aligned with the welding head 523, or to determine whether the mounting hole is within the allowable error range.
