Description

Technical Field

[0001] This utility model relates to the field of water hose processing technology, and in particular to a water hose external hole welding machine. Background Technology

[0002] Water hoses are movable, flexible tubular structures, typically made of rubber, synthetic materials, or woven fabric, used to transport water from a source to a target area, and are an important component of agricultural irrigation systems. When processing water hoses, it is often necessary to drill holes at multiple locations along the hose's length and weld connectors for connecting other components. For example, water hoses used in drip irrigation systems require multiple holes to be drilled along the hose's length and dripper holders to be welded on before the drippers are installed. In actual processing, drilling holes in the water hose often only requires drilling holes on one side and welding the components to be welded. However, water hoses are flexible and easily deformed, thus requiring support to prevent puncturing the hose during drilling or misalignment during welding. However, existing welding equipment lacks adequate support for the water hose, leading to defects and poor processing quality during drilling and welding operations. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a hose external hole welding machine, which can provide good support for the hose to be processed, thereby improving processing quality.

[0004] The water hose external hole welding machine according to an embodiment of the present utility model includes:

[0005] frame;

[0006] A conveying mechanism, mounted on the frame, is used to convey water hoses;

[0007] The tooling assembly includes a worktable and a support base. The worktable is disposed on the frame and has a first limiting part that defines the outlet through which the water supply hose passes. The support base is freely placed on the worktable and has an elastic mechanism that can move elastically. The support base is configured to be inserted into the inner cavity of the water supply hose and elastically abut against the inner wall of the water supply hose through the elastic mechanism. The support base and the first limiting part are sequentially distributed along the conveying direction of the water supply hose, and the first limiting part is used to abut against and limit the movement of the support base.

[0008] A processing component, disposed on the frame, is used to cut welding holes in the water hose sleeved on the support base, and to transport the welded part to the welding holes located on the support base and weld the welded part to the water hose.

[0009] The water hose external hole welding machine according to the embodiment of this utility model has at least the following beneficial effects:

[0010] By setting up a support base, the water hose can be supported by placing the support base inside the hose, which facilitates the processing components to perform processing operations such as cutting holes and welding on one side of the hose, and can avoid cutting through the hose when cutting holes. Furthermore, by setting up an elastic mechanism on the support base to elastically support the hose, the elastic mechanism can be used to tension the hose from the inside, making the hose at the support base taut and less prone to deformation, thereby improving the processing accuracy and processing quality of the hose by the processing components.

[0011] According to some embodiments of the present invention, along a first direction, a set of elastic mechanisms are provided on each of the opposite sides of the support base. The elastic mechanisms are configured to be elastically movable along the first direction, which is perpendicular to the conveying direction of the water hose and the vertical direction.

[0019] According to some embodiments of the present invention, the support base is provided with a vertically penetrating clearance hole, which allows the welded part to be partially embedded. Along the first direction, the workbench is provided with extrusion mechanisms on opposite sides of the support base. The extrusion mechanism includes an extrusion part, which can move along the first direction. As the extrusion part moves closer to the support base along the first direction, it can extrude the water belt sleeved on the support base and push the first roller to move elastically.

[0020] According to some embodiments of the present invention, the first limiting portion includes:

[0021] The first limiting roller is rotatably mounted on the worktable, and its rotation axis is perpendicular to the conveying direction of the water belt and the vertical direction.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0049] In the description of this utility model, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features or their sequential relationship.

[0051] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0052] Reference Figures 1 to 5 As shown, an embodiment of the water hose external hole welding machine of the present invention includes: a frame 100, a conveying mechanism 200, a tooling assembly, and a processing assembly.

[0053] The frame 100 is used to provide support and mounting carrier for various parts and components.

[0054] The conveying mechanism 200 is disposed on the frame 100. The conveying mechanism 200 is used to convey the water belt along the length direction of the water belt. The width direction of the water belt can be the width direction of the frame 100 (the water belt diagram is not shown).

[0055] The tooling assembly includes a worktable 300 and a support base 400. The worktable 300 is mounted on the frame 100 and can be fixed to the frame 100 with bolts or other fasteners. A first limiting part 310 is provided on the worktable 300, which defines the outlet 311 through which the water supply hose passes. The support base 400 is freely placed on the worktable 300 and is provided with an elastic mechanism 410 that can move elastically. The support base 400 is configured to be inserted into the inner cavity of the water hose and elastically abuts against the inner wall of the water hose through the elastic mechanism 410, thereby supporting the water hose from the inside to tighten it. Obviously, to ensure that the water hose can fit snugly on the support base 400... On the 00, the size of the support seat 400 needs to be slightly smaller than the inner cavity size of the water hose. Therefore, if the support seat 400 provides rigid support to the water hose, a gap will inevitably exist. However, this defect can be eliminated by using the elastic mechanism 410 to elastically support the water hose. In addition, along the conveying direction of the water hose, the support seat 400 and the first limiting part 310 are distributed in sequence. That is, when the conveying mechanism 200 conveys the water hose, the water hose first passes through the support seat 400 and then passes through the output port 311 of the first limiting part 310. The first limiting part 310 is used to abut against the support seat 400 and limit it. That is, the size of the output port 311 meets the condition that the support seat 400 cannot pass through, so as to limit the range of motion of the support seat 400.

[0056] A processing assembly is mounted on the frame 100. This assembly is used to cut welding holes in the hose fitted onto the support 400, and to transport the weldment 800 to the welding holes located on the support 400 and weld the weldment 800 to the welding holes in the hose. It is conceivable that the processing assembly can consist of multiple mechanisms, such as a mechanism for cutting holes, a mechanism for transporting the weldment 800, and a mechanism for welding the weldment 800 to the hose; additionally, when the hose is used in a drip irrigation system, the corresponding weldment 800 can be a dripper holder.

[0057] It should be noted that when the conveying mechanism 200 is conveying the water belt, there is friction between the water belt and the support seat 400. This friction will cause the support seat 400 to move closer to the first limiting part 310, so that the support seat 400 indirectly abuts against the first limiting part 310 through the water belt, thereby achieving a positioning effect on the support seat 400 and ensuring the accuracy of the processing position when the processing component processes the water belt.

[0058] When using the hose external hole welding machine of this embodiment, the processing preparation work is first carried out. The hose is manually placed on the support base 400 and passed through the output port 311 of the first limiting part 310. At the same time, the hose is connected to the conveying mechanism 200, and then the processing begins. During the processing, the conveying mechanism 200 intermittently conveys the hose at a certain regularity (the interval time is determined by the hole spacing of each welding hole on the hose and the conveying speed of the conveying mechanism 200, etc.). When the conveying mechanism 200 stops conveying the hose, the processing component works. The processing component first cuts welding holes on the hose placed on the support base 400, then moves the welding part 800 to the welding hole that was just cut, and then welds the welding part 800 to the welding hole of the hose, so that the welding part 800 and the hose are connected as one unit. Then the conveying mechanism 200 continues to convey the hose to perform the next position of hole opening, welding and other operations. The hose external hole welding machine of this embodiment, by setting a support base 400, can support the hose by placing the support base 400 inside the hose, thereby facilitating the processing components to perform processing operations such as cutting holes and welding on one side of the hose, and avoiding cutting through the hose when cutting holes; and by setting an elastic mechanism 410 on the support base 400 to elastically support the hose, the elastic mechanism 410 can be used to tension the hose from the inside, so that the hose at the support base 400 is taut and not easily deformed, thereby improving the processing accuracy of the processing components in processing the hose and improving the processing quality.

[0059] Reference Figure 1 As shown, in some embodiments of this utility model, the conveying mechanism 200 includes an unwinding roller 210, a winding roller 220, and a first driving member 230. The unwinding roller 210 and the winding roller 220 are arranged side by side on the frame 100. The unwinding roller 210 is used to unwind the water hose, and the winding roller 220 is used to wind the water hose. For example, the unwinding roller 210 and the winding roller 220 can be located at both ends of the length direction of the frame 100, and the unwinding roller 210 and the winding roller 220 can be arranged horizontally and extend along the width direction of the frame 100. The first driving member 230 is used to drive the winding roller 220 to rotate to wind the water hose, thereby automatically winding the water hose and automatically conveying the water hose. Of course, the unwinding roller 210 can also be correspondingly provided with a power structure to drive its rotation.

[0060] It is conceivable that the first driving component 230 could be a motor.

[0061] Reference Figure 2 and Figure 4As shown, in some embodiments of this utility model, along the first direction, a set of elastic mechanisms 410 are provided on each of the opposite sides of the support base 400. The elastic mechanisms 410 are configured to be elastically movable along the first direction, which is perpendicular to the conveying direction of the water hose and also perpendicular to the vertical direction. This arrangement allows for more even support of the water hose from within, resulting in good support effect and stable reliability. It is conceivable that the first direction can be the width direction of the frame 100.

[0062] Based on the above embodiments, it is conceivable that a set of elastic mechanisms 410 may include multiple elastic mechanisms 410, which are arranged at intervals along the conveying direction of the water hose to improve the support effect and stability. In this embodiment, multiple elastic mechanisms 410 are arranged at intervals along a second direction, and the conveying direction of the water hose at the support base 400 is consistent with the second direction. The second direction may be the length direction of the frame 100.

[0063] Reference Figure 2 and Figure 4 As shown, in some embodiments of the present invention, the elastic mechanism 410 includes a mounting base 411, a wheel frame 412, an elastic element, and a first roller 413. Mounting base 411 is mounted on support base 400, specifically by screws. Wheel frame 412 is movably mounted on mounting base 411 along a first direction, and is always constrained on mounting base 411 during movement. Elastic element is disposed between mounting base 411 and wheel frame 412, and is located inside mounting base 411, for applying an elastic force to wheel frame 412 in the first direction away from support base 400. First roller 413 is rotatably mounted on the end of wheel frame 412 away from support base 400, and the rotation axis of first roller 413 extends vertically. The peripheral wall of first roller 413 is used to abut against the inner wall of water hose. With the above structure, the elastic element can apply an elastic force to first roller 413 in the first direction away from support base 400, thereby making first roller 413 press against the inner wall of water hose. The structure is simple and practical, and the rotatable first roller 413 can reduce the friction force experienced by water hose during transmission.

[0064] Based on the above embodiments, it is conceivable that the elastic element can be a spring.

[0065] Reference Figure 2 and Figure 4As shown, in some embodiments of this utility model, along the first direction, a plurality of second rollers 420 are rotatably arranged on each of the opposite sides of the support base 400. The rotation axis of the second rollers 420 extends along the first direction, and the peripheral wall of the second rollers 420 protrudes from the surface of the support base 400 to abut against the inner wall of the water hose, thereby reducing the direct contact between the support base 400 and the water hose and reducing the wear on the water hose during the conveying process. In this embodiment, along the first direction, the first roller 413 is at least partially located on the side of the second rollers 420 away from the support base 400 to prevent the water hose from contacting the end face of the second rollers 420 and causing wear.

[0066] Reference Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments of this utility model, the support base 400 is provided with a vertically penetrating clearance hole 401. The clearance hole 401 allows the welded component 800 to be partially embedded. It is conceivable that the wall thickness of the water hose is relatively small, while the thickness of the welded component 800 varies. To ensure that the welded component 800 can precisely fit with the water hose after being placed on the welding hole, this embodiment provides a clearance hole 401 to avoid the welded component 800. Obviously, when the welded component 800 is partially embedded in the clearance hole 401, the welded component 800 will interfere with the support base 400 during subsequent water hose conveying. Therefore, in this embodiment, along the first direction, the worktable 300 is provided with extruders on opposite sides of the support base 400. The extrusion mechanism 320 includes an extrusion section 321, which can move along a first direction. As the extrusion section 321 moves closer to the support base 400 along the first direction, it can extrude the water hose sleeved on the support base 400 and push the first roller 413 to move elastically. Thus, when the water hose needs to be transported after the welded part 800 is welded, the extrusion sections 321 of the two extrusion mechanisms 320 can be moved closer to the support base 400 to extrude the water hose, causing the water hose to arch and the welded part 800 to disengage from the clearance hole 401, and then the water hose can be transported normally. When the water hose is transported to the corresponding position, the extrusion section 321 is reset, and the first roller 413 will also elastically reset, thereby continuing to tighten the water hose.

[0067] Based on the above embodiments, it is conceivable that the extrusion section 321 can be a plate-shaped structure; in addition, the extrusion mechanism 320 may also include a second driving member 322, which is used to drive the extrusion section 321 to move in the first direction. The second driving member 322 can be a cylinder, a hydraulic cylinder, an electric push rod, etc.

[0068] It is evident that the two compression mechanisms 320 can also limit the range of motion of the support 400 in the first direction.

[0069] Reference Figure 2 and Figure 3As shown, in some embodiments of this utility model, the first limiting part 310 includes a first limiting roller 312 and two second limiting rollers 313. The first limiting roller 312 is rotatably mounted on the worktable 300, and the rotation axis of the first limiting roller 312 extends along a first direction, that is, the rotation axis of the first limiting roller 312 is perpendicular to the conveying direction of the water belt and the vertical direction; the second limiting rollers 313 are rotatably mounted on the worktable 300 and distributed parallel to the first limiting roller 312, and the two second limiting rollers 313 are spaced apart along their own axial direction, that is, spaced apart along the first direction, and the two second limiting rollers 313 are located above the first limiting roller 312; wherein, the output port 311 is formed on the two first limiting rollers 312. The output port 311 formed between the two second limiting rollers 313 and the first limiting roller 312 is obviously in an inverted T-shape. In this way, the vertical distance between the second limiting rollers 313 and the first limiting roller 312 can be set to be smaller, so that when the water belt passes through the output port 311, it can contact the first limiting roller 312 and the second limiting roller 313, which can play a certain limiting role for the water belt. The two second limiting rollers 313 are spaced apart to avoid the welded parts 800 on the water belt.

[0070] Based on the above embodiments, it is conceivable that a second roller 420 is provided at one end of the support base 400 near the first limiting part 310. Here, the second roller 420 is indirectly abutted and limited by the water belt, the first limiting roller 312 and the second limiting roller 313, so as to reduce the wear of the water belt.

[0071] Reference Figure 2 and Figure 3 As shown, in some embodiments of this utility model, a second limiting part 330 is also provided on the workbench 300. The second limiting part 330 defines the input port 331 through which the water supply hose passes, and the support base 400 is located between the first limiting part 310 and the second limiting part 330. Specifically, along the second direction, the second limiting part 330 and the first limiting part 310 are arranged sequentially, and the input port 331 and the output port 311 are aligned, so that the water hose between the first limiting part 310 and the second limiting part 330 is distributed along the second direction. In this embodiment, by setting the second limiting part 330, on the one hand, it can cooperate with the first limiting part 310 to limit the range of motion of the support base 400, and on the other hand, it can cooperate with the first limiting part 310 to limit the distribution direction of the water hose, thereby improving the stability of the water hose processing process.

[0072] Reference Figure 2 and Figure 3As shown, in some embodiments of this utility model, the second limiting part 330 includes two third limiting rollers 332. The third limiting rollers 332 are rotatably disposed on the worktable 300, and the rotation axis of the third limiting rollers 332 is distributed along the first direction, that is, the rotation axis of the third limiting rollers 332 is perpendicular to the conveying direction of the water belt and the vertical direction. In addition, the two third limiting rollers 332 are arranged vertically at intervals, and the input port 331 is formed between the two third limiting rollers 332. By setting two third limiting rollers 332 to form the input port 331, the wear on the water belt can be reduced.

[0073] Reference Figure 1 , Figure 2 and Figure 5 As shown, in some embodiments of this utility model, the support base 400 is provided with a vertically penetrating clearance hole 401, and the processing components include a cutting mechanism 500, a conveying mechanism 600, and an ultrasonic welding mechanism 700. The cutting mechanism 500 is disposed on the frame 100 and is used to cut a welding hole on the hose located directly above the clearance hole 401. The clearance hole 401 can be used to avoid the cutting mechanism 500 from cutting the support base 400. The conveying mechanism 600 is disposed on the frame 100 and is used to convey the welded part 800 to the welding hole located directly above the clearance hole 401. The clearance hole 401 can also be used for partial embedding of the welded part 800 to ensure that the welded part 800 and the welding hole of the hose can be precisely matched. The ultrasonic welding mechanism 700 is disposed on the frame 100 and is used to weld the welded part 800 to the welding hole located directly above the clearance hole 401.

[0074] In some specific embodiments, refer to Figure 1 and Figure 5 As shown, the cutting mechanism 500 includes a third driving member 510, a first moving frame 520, a fourth driving member 530, a first lifting frame 540, a fifth driving member 550, and a cutter holder 560. The third driving member 510 is disposed on the frame 100. The first moving frame 520 is connected to the output end of the third driving member 510 and can move along the second direction under the drive of the third driving member 510. The fourth driving member 530 is disposed on the first moving frame 520. The first lifting frame 540 is connected to the output end of the fourth driving member 530 and can rise and fall under the drive of the fourth driving member 530. The fifth driving member 550 is disposed on the first lifting frame 540. The cutter holder 560 is rotatably disposed on the first lifting frame 540 about a vertical axis and is connected to the fifth driving member 550. The cutter holder 560 can rotate under the drive of the fifth driving member 550. A blade is mounted on the cutter holder 560 and can cut the water hose during the rotation of the cutter holder 560.

[0075] When cutting the water hose, first, the third drive member 510 drives the first moving frame 520 to move so that the cutter holder 560 is directly above the clearance hole 401. Then, the fourth drive member 530 drives the first lifting frame 540 to descend so that the blade on the cutter holder 560 contacts the water hose. Finally, the fifth drive member 550 drives the cutter holder 560 to rotate, thus cutting out the welding hole.

[0076] Based on the above embodiments, it is conceivable that the third driving component 510 can be a rodless cylinder, the fourth driving component 530 can be a motor-screw mechanism, and the fifth driving component 550 can be a motor. The fifth driving component 550 can be directly connected to the tool holder 560, or it can be connected to the tool holder 560 through a transmission mechanism of a synchronous belt and a synchronous pulley (which can be built into the first lifting frame 540). The structural components of the above-mentioned hole-cutting mechanism 500 are all conventional structures in the prior art, so their specific structures and working principles will not be described in detail here.

[0077] In some specific embodiments, refer to Figure 1 and Figure 5 As shown, a material picking position 101 is provided on the frame 100. This material picking position 101 is used to connect to the feeding mechanism (not shown) to receive the welding part 800 conveyed by the feeding mechanism. The conveying mechanism 600 includes: a sixth driving member 610, a second moving frame 620, a seventh driving member 630, a second lifting frame 640, and a clamping part 650. The sixth driving member 610 is disposed on the frame 100. The second moving frame 620 is connected to the output end of the sixth driving member 610 and can move along the first direction under the drive of the sixth driving member 610. The seventh driving member 630 is disposed on the second moving frame 620. The second lifting frame 640 is connected to the output end of the seventh driving member 630 and can be lifted and lowered under the drive of the seventh driving member 630. The clamping part 650 is disposed on the second lifting frame 640 and is used to clamp or release the welding part 800.

[0078] When handling the welded part 800, firstly, the sixth drive unit 610 drives the second moving frame 620 to move, so that the clamping part 650 is located above the material picking position 101. Then, the seventh drive unit 630 drives the second lifting frame 640 to descend to the material picking position 101. The welded part 800 is then clamped by the clamping part 650. Then, the seventh drive unit 630 drives the second lifting frame 640 to rise to the designated position. Then, the sixth drive unit 610 drives the second moving frame 620 to move so that the clamping part 650 is located above the clearance hole 401. Then, the seventh drive unit 630 drives the second lifting frame 640 to descend. Then, the clamping part 650 releases the welded part 800, so that the welded part 800 falls into the welding hole of the water hose, thus completing the handling of the welded part 800.

[0079] Based on the above embodiments, it is conceivable that the sixth driving component 610 can be a rodless cylinder, the seventh driving component 630 can be a motor screw mechanism, and the clamping part 650 can be a pneumatic gripper. All structural components of the above-mentioned conveying mechanism 600 are conventional structures in the prior art; therefore, their specific structures and working principles will not be described in detail here.

[0080] In some specific embodiments, refer to Figure 1 As shown, the ultrasonic welding mechanism 700 includes a welding head 710 and an eighth driving component (not shown). The eighth driving component is mounted on the frame 100. The welding head 710 is connected to the eighth driving component and can be raised and lowered under the drive of the eighth driving component. The welding head 710 is located directly above the clearance hole 401. During welding, the eighth driving component drives the welding head 710 to descend, moving the welding head 710 to fit the workpiece 800. Then, the ultrasonic welding mechanism 700 is activated to weld the workpiece 800 onto the water hose. The ultrasonic welding mechanism 700 is a common welding mechanism, and its specific structure and working principle will not be described in detail here.
