Description

Technical Field

[0001] This utility model relates to the field of pipe rolling machine technology, specifically a pipe rolling machine for air conditioning insulation pipes. Background Technology

[0002] Air conditioning insulation pipes are a crucial component of air conditioning systems. Their main function is to wrap around the refrigerant pipes to improve energy efficiency by reducing cooling loss and to prevent condensation from forming on the pipe surface. In modern large-scale production, long strips of insulation pipes coming off the production line need to be wound into neat coils for easy packaging, transportation, and storage. Therefore, specialized coiling machines have become an indispensable key piece of equipment in air conditioning insulation pipe production lines.

[0003] However, traditional semi-automatic or manual tube winding methods are inefficient, labor-intensive, and difficult to guarantee in terms of winding tightness and flatness, affecting product quality. While some fully automatic tube winding machines solve the efficiency problem, their structures are often quite complex, especially in the material unloading stage. They typically require additional complex robotic arms or multi-axis linkage mechanisms, which not only significantly increases the manufacturing cost and maintenance difficulty of the equipment but also raises the failure rate. This makes it difficult to meet the demands of modern manufacturing for high-efficiency, low-cost, and highly reliable equipment. Therefore, a new type of air conditioning insulation pipe winding machine is needed to address the shortcomings of existing methods. Utility Model Content

[0004] Technical problems to be solved

[0005] However, traditional semi-automatic or manual tube winding methods are inefficient, labor-intensive, and difficult to guarantee the tightness and flatness of the winding, which affects product quality.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an air conditioning insulation pipe rolling machine, comprising:

[0008] support;

[0009] A tube winding mechanism, rotatably connected to the front side of the bracket, is used to clamp and rewind the tube body;

[0010] A limiting mechanism is movably disposed on the front side of the bracket and located on the periphery of the tube winding mechanism. It is used to limit the axial position of the tube body during the winding process and to push the rolled tube body forward after winding is completed.

[0011] Hydraulic cylinder one is mounted on the bracket, and its output end is connected to the limiting mechanism for driving the limiting mechanism to move back and forth.

[0012] The limiting mechanism includes an automatically flip-up side plate. When the limiting mechanism is pushed forward to a predetermined position by the hydraulic cylinder, the side plate automatically flips outward to expose and facilitate the removal of the rolled tube.

[0013] Furthermore, the tube winding mechanism includes:

[0014] A turntable, which is rotatably connected to the front side of the bracket via a rotating shaft;

[0015] A spiral-shaped limiting member is fixed to the front side of the turntable and has a first end and a second end that are disposed opposite to each other. The first end is away from the axis of the turntable, and the second end is close to the axis of the turntable and is movable.

[0016] Hydraulic cylinder two is fixed at the center of the turntable, and its telescopic rod is connected to the second end for driving the second end to move closer to or away from the first end in order to clamp or release the end of the tube.

[0017] Furthermore, the limiting mechanism includes:

[0018] A ring-shaped clamp is fitted onto the outside of the turntable;

[0019] Clamping plate two, which serves as the automatically flip-up side plate, is movably connected to the front side of clamping plate one via a pivot.

[0020] A flip trigger mechanism is provided between the bracket and the second clamping plate, and is used to drive the second clamping plate to flip when the first clamping plate moves to a predetermined position.

[0021] Furthermore, the flip trigger mechanism includes:

[0022] The gear is fixedly mounted on the rotating shaft of the clamp plate two;

[0023] A toothed plate, which is fixedly installed on the front side of the bracket;

[0024] When clamping plate one drives clamping plate two to move forward, the gear can mesh with the toothed plate and roll along the toothed plate as it continues to move forward, thereby causing clamping plate two to flip outward.

[0025] Furthermore, several guide rods arranged in a circular array are fixedly connected to the back side of the clamping plate one. The bracket has corresponding guide holes that match the guide rods. The guide rods can slide through the guide holes and extend into the bracket to assist the clamping plate one in moving smoothly.

[0026] Furthermore, the hydraulic cylinder is fixedly installed on the back side of the bracket, and its telescopic rod passes through the bracket and is fixedly connected to the back side of the clamping plate.

[0027] Furthermore, it also includes:

[0028] A servo motor is mounted on the back side of the bracket, and its output shaft is connected to the rotating shaft of the tube winding mechanism to drive the tube winding mechanism to rotate.

[0029] Compared with existing technologies, this air conditioning insulation pipe rolling machine has the following advantages:

[0030] I. This utility model achieves rapid and secure clamping and automatic release of the tube end by setting up a tube winding mechanism composed of a turntable and a spiral limiting component, and using a hydraulic cylinder to drive the movable end of the limiting component. This replaces the traditional manual binding or complex clamps, and significantly improves the automation level and work efficiency of loading and unloading.

[0031] Second, this utility model sets a limiting mechanism that can move back and forth around the tube winding mechanism. This mechanism forms a ring constraint during winding, which effectively restricts the axial movement of the tube body and ensures that the tube body can be arranged tightly and flat along the spiral limiting member, thereby ensuring the regularity and consistency of the finished coil and improving product quality.

[0032] Third, this utility model designs the limiting mechanism as an integral structure driven by a hydraulic cylinder, and integrates a flip trigger mechanism on the clamping plate that meshes with a fixed toothed plate, thereby realizing the automatic opening of the side plate during the ejection of the finished coil. The entire process does not require manual intervention, which greatly simplifies the material unloading process and reduces the difficulty of operation and labor intensity.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] like Figure 1-4 As shown, this utility model provides a technical solution: an air conditioning insulation pipe rolling machine, which mainly consists of a support 1, a rolling mechanism 2, a limiting mechanism, a hydraulic cylinder 3, and a servo motor 11. The support 1 is the installation foundation of the entire equipment and is a stable box-type or frame-type structure. Its front side is the working area, and its back side is the power and drive area.

[0040] like Figure 1 and Figure 4 As shown, the tube winding mechanism 2 is the core component for performing the winding action. It is rotatably connected to the front center of the support 1 via a rotating shaft. The mechanism includes a turntable 201 and a spiral limiting member 202. The turntable 201 is circular and is movably connected to the front of the support 1 via the rotating shaft. The spiral limiting member 202 is welded and fixed to the front surface of the turntable 201. It extends spirally outward from near the axis to form a guide groove similar to an Archimedean spiral. The limiting member 202 has a fixed first end 4 (located outside the spiral) and a movable second end 5 (located inside the spiral). At the center of the turntable 201, a hydraulic cylinder 203 is fixedly installed. Its telescopic rod extends forward and is hinged to the second end 5. When the telescopic rod of the hydraulic cylinder 203 extends, it pushes the second end 5 toward the first end 4 to form a clamping opening for clamping the end of the tube to be wound. When the telescopic rod retracts, the second end 5 moves away, releasing the tube.

[0041] The function of the limiting mechanism is to limit the tube body axially during winding and to push it out after winding is completed. It includes a ring-shaped clamping plate 6, a clamping plate 7, and a flipping trigger mechanism. The clamping plate 6 is ring-shaped and is sleeved on the outside of the turntable 201 of the tube winding mechanism 2. On its back side, several guide rods 10 distributed in a circular array are fixedly connected. These guide rods 10 pass through the corresponding guide holes on the bracket 1 to ensure that the clamping plate 6 can only move smoothly along the axial direction. The clamping plate 7 is hinged to the front edge of the clamping plate 6 through a pivot and can be flipped outward like a door.

[0042] Hydraulic cylinder 3 is the power source for pushing the limit mechanism. It is fixedly installed on the back side of bracket 1, and its telescopic rod passes through the plate wall of bracket 1 and is fixedly connected to the back side of clamping plate 6.

[0043] like Figure 1 and Figure 3 As shown, the flipping trigger mechanism is the key to achieving automatic material unloading. It includes a gear 8 and a toothed plate 9. The gear 8 is fixedly mounted on the rotating shaft of the clamping plate 7, and the toothed plate 9 is installed at a specific position on the front side of the bracket 1. When the hydraulic cylinder 3 pushes the clamping plate 6 forward, the clamping plate 7 moves in the same direction. When it moves to the predetermined position, the gear 8 just meshes with the toothed plate 9. As the hydraulic cylinder 3 continues to push forward, the gear 8 will roll along the toothed plate 9, thereby forcibly driving the rotating shaft of the clamping plate 7 to rotate, causing the clamping plate 7 to open outward.

[0044] The servo motor 11 is mounted on the back side of the bracket 1, and its output shaft is connected to the shaft drive of the coupling turntable 201 to provide precise and controllable rotational power for winding.

[0045] The workflow is as follows:

[0046] When the equipment is initially in standby mode, both hydraulic cylinder 3 and hydraulic cylinder 203 are in the retracted state. The operator manually places the end of the air conditioning insulation pipe between the first end 4 and the second end 5 of the spiral limiting member 202. Then the control system issues a command, and the telescopic rod of hydraulic cylinder 203 extends, pushing the second end 5 to clamp the end of the pipe.

[0047] Servo motor 11 starts, driving turntable 201 to rotate. The tube end is fixed, and the tube body begins to be neatly wound layer by layer and circle by circle around the spiral limiting member 202, guided by the spiral limiting member 202. During this process, clamping plate 6 and clamping plate 7 of the limiting mechanism form a ring constraint, restricting the axial displacement of the tube body and ensuring the flatness of the winding reel. When the preset winding length or number of turns is reached, servo motor 11 stops, hydraulic cylinder 203 retracts to release the tube end, and then the telescopic rod of hydraulic cylinder 3 extends, pushing the entire limiting mechanism. The mechanism (including clamping plate 6 and clamping plate 7) and the coiled tube inside it move forward together, disengaging it from the turntable 201 of the tube winding mechanism 2. During the pushing process, the gear 8 on clamping plate 7 meshes with the toothed plate 9, forcing clamping plate 7 to flip outward and open, allowing the operator or the conveyor belt below to easily remove the coiled tube from the side. After the material is unloaded, hydraulic cylinder 3 retracts, driving the limit mechanism to reset. During the reset process, gear 8 rolls in the opposite direction, causing clamping plate 7 to automatically close and return to the initial circular state, ready for the next work cycle.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
