[0035] Figure 1 This is a schematic diagram of the structure of an automatic cutting device for thermal insulation sleeves according to the present invention. Figure 2 This is a schematic diagram of the conveying mechanism of an automatic cutting device for thermal insulation sleeves according to this utility model. Figure 3 This is a schematic diagram of the cutting mechanism of an automatic thermal insulation sleeve cutting device according to this utility model. Figure 4 This is a schematic diagram of the feeding and monitoring mechanism of an automatic cutting and insulation sleeve device according to the present invention. Figure 1-4 As shown, an automatic cutting device for thermal insulation sleeves according to a preferred embodiment is illustrated, comprising: a housing 1, on which a conveying mechanism 2 and a cutting mechanism 3 are mounted. The conveying mechanism 2 is used to convey thermal insulation sleeves along a first direction. The cutting mechanism 3 is located at the unloading end of the conveying mechanism 2 and is used to uniformly cut the thermal insulation sleeves. The cutting mechanism 3 includes: a mounting frame 31, a mounting shaft 32, a blade holder 33, a blade 34, and a driving member 36. The mounting frame 31 is mounted on the housing 1, the mounting shaft 32 is mounted on the mounting frame 31, one end of the blade holder 33 is rotatably sleeved on the outside of the mounting shaft 32, the blade 34 is mounted on the blade holder 33, and the length direction of the blade 34 is perpendicular to the first direction. The driving member 36 is connected to the blade holder 33 for driving the blade holder 33 to periodically reciprocate around the axial direction of the mounting shaft 32.

[0036] Specifically, the insulation sleeve to be cut is placed at the starting position of the conveying mechanism 2, the device is started, and the conveying mechanism 2 starts to work, conveying the insulation sleeve along the first direction. When the insulation sleeve is conveyed to the position of the cutting mechanism 3 (the unloading end of the conveying mechanism 2), the driving component 36 starts to move, driving the blade holder 33 to rotate periodically around the axial direction of the mounting shaft 32. Since the blade 34 is mounted on the blade holder 33 and its length direction is perpendicular to the first direction, the reciprocating rotation of the blade holder 33 causes the blade 34 to cut the insulation sleeve, thereby achieving uniform cutting of the insulation sleeve.

[0037] In this application, the automatic conveying and cutting of the insulation sleeve is achieved through the coordinated work of the conveying mechanism 2 and the cutting mechanism 3, which improves the cutting efficiency, avoids the safety risks of manual cutting, and at the same time, the design of the cutting mechanism 3 ensures the uniformity of the cutting and improves the cutting quality of the insulation sleeve.

[0038] Furthermore, in a preferred embodiment, the drive frame is an electric cylinder, with one end hinged to the tool holder 33 and the other end hinged to the housing 1. When the drive component 36 uses an electric cylinder, the electric cylinder performs telescopic movements according to a preset program. With one end hinged to the tool holder 33 and the other end hinged to the housing 1, the electric cylinder, during telescopic movement, drives the tool holder 33 to periodically reciprocate around the mounting shaft 32 via the hinge point, thereby causing the blade 34 to cut the insulation sleeve.

[0039] In this application, the electric cylinder serves as the driving component 36, which can precisely control the extension and retraction amount and movement speed, thereby precisely controlling the rotation amplitude and cutting speed of the tool holder 33, making the cutting process more stable and accurate, and improving the consistency of cutting quality.

[0040] Of course, in some embodiments, the drive component 36 may also be a cylinder, hydraulic cylinder, etc.

[0041] Furthermore, in a preferred embodiment, a connecting portion 331 is formed on the exterior of one end of the tool holder 33, and one end of the electric cylinder is hinged to the connecting portion 331. The connecting portion 331 facilitates the hinged connection between the electric cylinder and the tool holder 33, making the connection more stable and reliable. At the same time, it facilitates the adjustment and optimization of the connection position and angle between the electric cylinder and the tool holder 33, ensuring the efficiency and accuracy of power transmission and improving the operational stability of the cutting mechanism 3.

[0042] Furthermore, as a preferred embodiment, the blade 34 is a double-edged blade 34. When the blade 34 is a double-edged blade 34, in the initial cutting stage, one edge of the blade 34 cuts the insulation sleeve. When this edge wears down, it is not necessary to replace the entire blade 34; simply rotate the blade 34 180° and use the other edge to continue the cutting operation.

[0043] Furthermore, as a preferred embodiment, both ends of the blade 34 are mounted on the blade holder 33 by screws 35. The screw 35 installation method is simple and convenient, facilitating the installation, disassembly, and replacement of the blade 34, while ensuring the stability of the blade 34 during the cutting process and ensuring cutting quality.

[0044] Furthermore, in a preferred embodiment, a guide structure is also installed on the housing 1. The guide structure is located at the unloading end of the conveying mechanism 2. The guide structure includes two guide tubes 4, which are coaxially arranged and spaced apart along a first direction, with a blade 34 located between the two guide tubes 4. After the insulation sleeve reaches the unloading end under the conveying mechanism 2, it enters the guide structure. The two guide tubes 4 are coaxially arranged and spaced apart along the first direction. The insulation sleeve maintains linear movement under the guidance of the two guide tubes 4, ensuring that the insulation sleeve is accurately positioned when it reaches the cutting mechanism 3. The blade 34 is located between the two guide tubes 4, and when the insulation sleeve reaches the appropriate position, the blade 34 cuts it.

[0045] The guiding structure in this application can accurately guide the movement direction of the insulation sleeve, ensure the positional accuracy of the insulation sleeve during cutting, make the cutting more accurate, reduce the cutting error caused by the positional deviation of the insulation sleeve, and improve the product qualification rate.

[0046] Furthermore, in a preferred embodiment, the conveying mechanism 2 includes two conveying components 21, which are arranged vertically and correspondingly, and the distance between the two conveying components 21 matches the outer diameter of the insulation sleeve. Each conveying component 21 includes two conveying rollers 211 and a conveyor belt 212. The two conveying rollers 211 are rotatably mounted on the housing 1 along a first direction, and the conveyor belt 212 is connected between the two conveying rollers 211. After the device is started, the two conveying components 21 begin to work. The two conveying rollers 211 in each conveying component 21 rotate under power drive, driving the conveyor belt 212 to move. The insulation sleeve is placed between the two conveying components 21. Since the two conveying components 21 are arranged vertically and correspondingly and the distance matches the outer diameter of the insulation sleeve, the insulation sleeve is clamped between the two conveyor belts 212 and is stably conveyed along the first direction as the conveyor belt 212 moves.

[0047] Each conveying assembly 21 also includes a motor, which is mounted on the housing 1 and is connected to one of the conveying rollers 211 for driving the conveying roller 211 to rotate, thereby causing the conveyor belt 212 to rotate.

[0048] In this application, the two conveying components 21 are arranged vertically and vertically, with the spacing matching the outer diameter of the insulation sleeve. This enables stable clamping and conveying of the insulation sleeve, preventing it from shifting or shaking during conveying and ensuring the accuracy and stability of the conveying process.

[0049] Furthermore, in a preferred embodiment, each conveying assembly 21 further includes a tension roller 213 rotatably mounted on the housing 1 and located on one side of the conveying rollers 211, with the conveyor belt 212 connected between the two conveying rollers 211 and the tension roller 213. The tension roller 213 increases the tension of the conveyor belt 212, preventing slippage and ensuring friction between the conveyor belt 212 and the conveying rollers 211, thereby improving the stability and reliability of the conveying process and ensuring that the insulation sleeve can be conveyed at a predetermined speed and direction.

[0050] Furthermore, in a preferred embodiment, each conveying assembly 21 further includes a plurality of support rollers 214 mounted on the housing 1, and a plurality of support rods are equally spaced between the two conveying rollers 211 along a first direction. The plurality of support rollers 214, equally spaced along the first direction, provide support to the conveyor belt 212 when the insulation sleeve is conveyed on the conveyor belt 212, preventing the conveyor belt 212 from sagging due to gravity or other factors during the conveying of the insulation sleeve. The conveyor belt 212 remains flat under the support of the support rollers 214, thereby ensuring that the insulation sleeve can move smoothly on the conveyor belt 212.

[0051] Furthermore, as a preferred embodiment, a feed conduit 5 is also installed on the frame. The feed conduit 5 is located at the feed end of the conveying mechanism 2 and is coaxially arranged with the guide tube 4. The insulation sleeve to be cut is inserted into the feed conduit 5, which is located at the feed end of the conveying mechanism 2 and coaxially arranged with the guide tube 4. Under the guidance of the feed conduit 5, the insulation sleeve smoothly enters the conveying mechanism 2 and is then conveyed to the guiding structure and cutting mechanism 3 for cutting according to the previous workflow.

[0052] In this application, the feed conduit 5 and the guide tube 4 are coaxially arranged, which can provide a continuous and accurate guiding channel for the insulation sleeve, so that the insulation sleeve can maintain linear movement throughout the entire process from feeding to conveying to cutting, ensuring that the movement trajectory of the insulation sleeve in the device is accurate and improving the overall operational stability and cutting accuracy of the device.

[0053] More preferably, an installation cavity 13 is formed inside the housing 1, and the conveying mechanism 2, the cutting mechanism 3, the guiding mechanism, and the feeding conduit 5 are all arranged in the installation cavity 13. The installation cavity 13 has a feeding port 11 on one side and a discharging port 12 on the other side. The feeding port 11 is coaxially connected with the feeding conduit 5, and the discharging port 12 is coaxially connected with a guide pipe 4 away from the conveying mechanism 2.

[0054] Furthermore, the front of the housing 1 has an observation hole 14 that communicates with the discharge port 12.

[0055] Even better, the housing 1 is also equipped with a feeding monitoring mechanism 6, which is used to detect whether there is material in the feed inlet 11. It includes a photoelectric sensor 62 and an indicator light 61. The signal received by the photoelectric sensor 62 is transmitted to the indicator light 61. In the normally open state, the indicator light 61 is red. When a signal is received that material has entered the device, the signal is sent to the indicator light 61 to turn on the green light. After the insulation sleeve has completed automatic cutting, the photoelectric sensor 62 does not receive any material and sends a signal to the indicator light 61 to turn on the red light. This is used for personnel to monitor the material feeding status and facilitate timely replenishment of material.

[0056] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
