Description

Technical Field

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

[0002] Air conditioning insulation pipes are an indispensable auxiliary material in modern air conditioning installation projects. Their main function is to wrap refrigerant pipes, reduce heat loss, and prevent condensation from forming on the pipe surface. During the installation of air conditioning systems, precise openings often need to be made in the insulation pipes according to the actual layout to connect branch pipes, pressure gauges, or other testing equipment. Currently, the opening work for insulation pipes mainly relies on manual operation or the use of some simple auxiliary tools.

[0003] However, some existing simple opening devices still have obvious defects. These devices usually have a large guide groove to accommodate the pipe body. However, it is this excessive gap that makes it impossible for the pipe body to be effectively radially positioned and axially constrained before entering the cutting area. When the cutting tool applies force to the pipe body, the pipe body is very easy to shake or deviate in the wide guide groove, causing the actual cutting path to deviate from the predetermined center line. This results in skewed cuts of varying depths, which seriously affects the quality and consistency of the opening and makes it difficult to meet the process requirements of air conditioning installation. Therefore, an air conditioning insulation pipe opening machine is needed to solve the existing shortcomings. Utility Model Content

[0004] Technical problems to be solved

[0005] Existing simple opening devices have excessively large gaps in the guide grooves, which cannot effectively position the tube body. This causes the tube body to easily shake and shift during cutting, resulting in skewed cuts and poor quality.

[0006] Technical solution

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

[0008] Base;

[0009] Two symmetrically arranged support members are fixed to the base and are arranged opposite each other along the conveying direction of the tube.

[0010] Two clamping and conveying mechanisms are respectively disposed on the two support members. Each clamping and conveying mechanism has a working surface for contacting and conveying the tube. The two working surfaces are arranged opposite to each other to form a clamping channel for clamping and conveying the tube.

[0011] A synchronous control mechanism is set on the base, and its power output end is connected to the two clamping and conveying mechanisms for driving the two clamping and conveying mechanisms to move synchronously in opposite directions, so that the tube in the clamping channel is conveyed along its axial direction in a stable clamping state.

[0012] A cutting device is disposed across the space between the two supports and at a predetermined cutting position in the clamping channel, for radially cutting the tube conveyed to that position.

[0013] An inlet component, fixed to the inlet end of the base in the tube conveying direction, is used to guide the tube to be cut into the clamping channel.

[0014] Furthermore, the support member includes:

[0015] Several support columns are vertically fixed to the base;

[0016] The base plate is horizontally fixed to the top of the support column;

[0017] A connecting column is vertically fixed to the top of the base plate;

[0018] The top plate is horizontally fixed to the top of the connecting column;

[0019] The bottom plate and the top plate are in a triangular structure that are parallel to each other, and the clamping and conveying mechanism is disposed between the bottom plate and the top plate.

[0020] Furthermore, the clamping and conveying mechanism includes:

[0021] Three conveyor wheels are rotatably mounted between the bottom plate and the top plate via a rotating shaft, and the axes of the three conveyor wheels form a triangular distribution.

[0022] A closed-loop conveyor belt is tensioned and fitted around the outer periphery of the three conveyor wheels, forming a triangular transmission circuit;

[0023] Several connecting blocks are fixed at equal intervals to the outer surface of the conveyor belt;

[0024] A clamping block is fixedly connected to one end of each connecting block away from the conveyor belt. The outer surface of the clamping block forms the working surface, which is used to provide multi-point limiting clamping of the tube during the conveying process.

[0025] Furthermore, the synchronization control mechanism includes:

[0026] Gear 1 is coaxially fixed to the shaft of any of the conveying wheels in one of the clamping and conveying mechanisms;

[0027] Gear 2 is rotatably connected to the bottom of the base plate of the support member where gear 1 is located via a rotating shaft, and meshes with gear 1;

[0028] Synchronizing pulley one is coaxially fixed to the rotating shaft of gear two;

[0029] Synchronous wheel two is rotatably connected to the bottom of the base plate of another support member via a rotating shaft;

[0030] A synchronous belt is tensioned and fitted around the outer circumference of synchronous pulley one and synchronous pulley two, forming a synchronous transmission structure.

[0031] Furthermore, the synchronization control mechanism also includes a servo motor, which is fixed on the base and its output shaft is driven to the rotating shaft of the first gear. The servo motor transmits power to the two clamping and conveying mechanisms through the first gear, the second gear, the first synchronous pulley, the second synchronous pulley, and the synchronous belt, so as to precisely control the two conveyor belts to rotate synchronously in opposite directions.

[0032] Furthermore, the cutting device is fixed on the top plate of the two support members, and its cutting execution end is located on the longitudinal center line of the clamping channel, ensuring that when the tube is cut, the cutting force acts on the center of the area where the tube is clamped on both sides, so as to maintain the stability of the tube during cutting and ensure that the cut is straight.

[0033] Furthermore, it also includes an outlet component, which is fixed to the outlet end of the base in the tube conveying direction and located between the two support components, for receiving and guiding the cut tube to move smoothly out of the clamping channel.

[0034] Compared with existing technologies, this air conditioning insulation pipe opening machine has the following advantages:

[0035] I. This utility model achieves synchronous reverse clamping and transmission of the tube body by setting two clamping and conveying mechanisms driven by a synchronous control mechanism, ensuring that the tube body remains stable and centered throughout the entire processing process. This solves the problem of easy shaking and deviation of the tube body during simple mechanical cutting, and creates the preconditions for high-precision cutting.

[0036] II. This utility model designs the clamping and conveying mechanism as a triangular transmission circuit consisting of three conveying wheels and a conveyor belt, and sets a connecting block with clamping blocks on the conveyor belt, forming a multi-point flexible clamping of the pipe body. This structure not only clamps firmly, but also can adapt to pipe diameter changes within a certain range. At the same time, the sliding cooperation between the connecting block and the top and bottom plates ensures the smoothness and straightness of the conveyor belt operation.

[0037] Third, by setting inlet and outlet components at the front and rear ends of the base respectively, this utility model realizes the automatic introduction and smooth removal of the tube body. Combined with the automated process of clamping, conveying and cutting, it forms a complete assembly line operation, which greatly reduces the labor intensity of manual operation and significantly improves the production efficiency of air conditioning insulation pipe openings.

[0043] 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.

[0044] like Figure 1-4 As shown, this utility model provides a technical solution: an air conditioning insulation pipe opening machine, which aims to solve the problems of low efficiency and poor precision of manual cutting in the prior art, as well as the easy shaking of the pipe body and uneven cut when simple mechanical cutting. Its core concept is to automatically transmit the pipe body to the cutting position to complete the precise cutting by using a set of synchronous reverse motion clamping and conveying mechanism 3, in a stable clamping state.

[0045] The overall structure of the opening machine is mounted on a sturdy base 1 to ensure the stability of the entire equipment during operation. On the base 1, two support members 2 are symmetrically fixed along the direction of pipe conveying. These two support members 2 constitute the main frame of the equipment and are used to support the clamping and conveying mechanism 3 and the cutting device 5. In order to guide the insulation pipe to be processed smoothly into the equipment, a trumpet-shaped guide member 6 is fixed at the front entrance of the base 1. Its opening gradually narrows, which can easily guide the pipe to the subsequent processing station.

[0046] like Figure 1 and Figure 2 As shown, each support component 2 consists of several support columns 201, a base plate 202, a connecting column 203, and a top plate 204, arranged from bottom to top. The support columns 201 are vertically fixed to the base 1, providing basic support. The base plate 202 is horizontally installed on top of the support columns 201. The connecting column 203 is vertically fixed to the center of the base plate 202, and the top plate 204 is horizontally fixed to the top of the connecting column 203. A key design feature is that both the base plate 202 and the top plate 204 are designed in a triangular shape. This structure is not only stable but also provides a mounting foundation for the triangular layout of the subsequent clamping and conveying mechanism 3.

[0047] On the opposite side of the two support members 2, i.e., the inner side, a clamping and conveying mechanism 3 is installed. The two clamping and conveying mechanisms 3 are arranged opposite each other, forming a clamping channel for the tube body to pass through. The core of each clamping and conveying mechanism 3 is a triangular conveying system. Specifically, three conveying wheels 301 are rotatably mounted at the three corners of the base plate 202 and top plate 204 of the triangle via bearings and shafts. A closed-loop conveyor belt 302 is tightly fitted around the outer periphery of these three conveying wheels 301, forming a stable triangular transmission circuit. In order to achieve effective clamping of the tube, several connecting blocks 303 are fixed at equal intervals on the outer surface of the conveyor belt 302. The top of each connecting block 303 slides with the side of the top plate 204, and the bottom of each connecting block 303 slides with the side of the base plate 202, thereby guiding the movement of the connecting block 303. Furthermore, a clamping block 304 is firmly installed on each connecting block 303. When the conveyor belt 302 moves, these clamping blocks 304 also move, and their outer surfaces form a working surface that directly contacts the tube. Through multi-point contact, the side of the tube is stably limited and clamped.

[0048] like Figure 1 , Figure 2 and Figure 3As shown, in order to achieve precise synchronous reverse movement of the two clamping and conveying mechanisms 3, the equipment is equipped with a synchronous control mechanism 4. The power source of this mechanism is a servo motor 406 fixed on the base 1, which can provide precise and controllable speed and torque. The output shaft of the servo motor 406 is driven and connected to the shaft of a gear 401. This gear 401 is coaxially fixed on the shaft of any one of the conveying wheels 301 of one of the clamping and conveying mechanisms 3. At the bottom of the base plate 202 of the support member 2 where the gear 401 is located, a gear 402 is rotatably mounted on a shaft. The gear 402 meshes with the gear 401. On the same shaft of the gear 402, a synchronous pulley 403 is also coaxially fixed. At the bottom of the base plate 202 of the other support member 2, a synchronous pulley 404 is also rotatably mounted on a shaft. Finally, a synchronous belt 405 is tensioned and fitted around the outer circumference of the synchronous pulleys 403 and 404, forming a synchronous belt drive structure.

[0049] During operation, the servo motor 406 starts, driving gear 1 401 to rotate. Gear 1 401 transmits power to gear 2 402 through meshing with gear 2 402, and changes the direction of rotation. Gear 2 402 drives the coaxial synchronous pulley 1 403 to rotate, and then transmits the power and direction of rotation synchronously to synchronous pulley 2 404 on another support 2 through the synchronous belt 405. Finally, the power is transmitted to the clamping and conveying mechanism 3 on the other side. Through this series of precise gear and synchronous belt 405 transmissions, it is ensured that the conveyor belts 302 of the two clamping and conveying mechanisms 3 can operate synchronously at the same linear speed but in opposite directions. In this way, when the tube enters the clamping channel, the clamping blocks 304 on both sides will clamp the tube synchronously at opposite speeds and smoothly convey it forward in a cooperative manner.

[0050] The cutting device 5 is securely mounted on top of the two support members 2, spanning across the clamping channel. Its cutting execution end, such as a high-speed rotating cutter, is precisely positioned on the longitudinal center line of the clamping channel. This position is crucial because it is exactly in the middle of the area where the tube is clamped on both sides. When the servo motor 406 drives the clamping and conveying mechanism 3 to transport the tube to this position, the cutting device 5 starts and performs radial cutting on the tube. Because the tube is clamped evenly and stably in all directions at the moment of cutting, any shaking or displacement can be effectively prevented, thus ensuring a flat and straight cut.

[0051] After the cutting is completed, the pipe body continues to move forward under the push of the subsequent clamping block 304, and finally moves out from the outlet end of the clamping channel. In order to ensure that the cut pipe section can leave the equipment smoothly and stably, an outlet component 7 is also provided at the rear outlet of the base 1. The outlet component 7 is a pipe body that is moved out and guided into the next process or collection box.

[0052] 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.
