Description

Technical Field

[0001] This utility model belongs to the technical field of cutting devices, specifically relating to a cutting device for the production of thermal insulation materials. Background Technology

[0002] Insulated pipes not only possess advanced technology and practical performance unmatched by traditional underground and overhead pipelines, but also offer significant social and economic benefits, serving as a powerful measure for energy conservation in heating systems. With the further improvement and development of this advanced technology, direct burial of heating pipelines to replace underground and overhead methods is inevitable. Because the rigid polyurethane foam insulation layer is tightly bonded to the outer surface of the steel pipe, it prevents the penetration of air and water, providing excellent corrosion protection.

[0003] Existing insulation pipe cutting equipment typically operates by processing single pipes on multiple lines, which occupies a lot of space and resources. In addition, due to different equipment errors, the length of insulation pipes varies between different production lines. Furthermore, the exposed cutting equipment poses a significant safety hazard to workers on site. Summary of the Invention

[0004] This utility model provides a cutting device for the production of thermal insulation materials. Its purpose is to solve the problems that existing thermal insulation pipe cutting devices usually adopt a single-piece processing and multi-line operation method, which occupies a lot of space and resources. At the same time, due to different equipment errors, the length of thermal insulation pipes is not the same between different production lines. In addition, the exposed cutting device also poses a significant safety hazard to on-site workers.

[0005] This utility model provides a cutting device for producing thermal insulation materials, including a mold. The mold has multiple feed inlets and discharge outlets on both sides. The feed inlets of the mold are connected to an extruder. The mold has a cutting mechanism inside, which is installed in the mold through a limiting mechanism.

[0006] Furthermore, a branch feed pipe is installed in the feed inlet, and a main pipe is integrally formed at one end of the branch feed pipe toward the extruder. The main pipe is connected to the extruder, and the other end of the branch feed pipe extends toward the discharge port of the die.

[0007] By adopting the above technical solution, and by setting multiple feed inlets and outlets and connecting them to the extruder, multiple insulation pipes can be extruded at one time, which significantly improves production efficiency, reduces equipment space occupation, and avoids the problem of inconsistent finished product lengths caused by equipment errors in multiple independent production lines. The cutting mechanism is built into the mold, effectively avoiding the safety hazards caused by exposure. The integrated molding structure of the branch feed pipe and the main pipe can evenly distribute the molten insulation material extruded by the extruder into multiple branch feed pipes, ensuring that the material flow rate and pressure at each outlet are consistent, thereby ensuring that the produced insulation pipes are of consistent size and uniform quality.

[0008] Furthermore, the limiting mechanism includes horizontal grooves provided on both sides of the mold wall, the horizontal grooves on both sides are interconnected, the lower side of the horizontal groove is provided on the upper surface of the mold and a limiting groove is provided on the mold on both sides of the diversion feed pipe, the multiple vertical grooves are provided on the mold, the multiple vertical grooves are equidistantly distributed axially upwards, and the vertical grooves are connected to the horizontal grooves and the outside.

[0009] By adopting the above technical solution, the horizontal groove, the limiting groove and the vertical groove together form a three-dimensional guiding and limiting system. The horizontal groove realizes horizontal movement guidance, the limiting groove prevents the cutting mechanism from deviating in the vertical direction, and the multiple vertical grooves enable the cutting mechanism to be accurately positioned at different work positions along the mold axis, thereby realizing fixed-length cutting of different lengths. The structure is compact and easy to adjust.

[0010] Furthermore, the cutting mechanism includes a sliding block that slides in a horizontal groove, a limiting block fixed at the bottom of the sliding block, the limiting block sliding in a limiting groove, a pulling block fixed on the outer side of the sliding block, and a handle fixed on the pulling block.

[0011] By adopting the above technical solution, the sliding block slides in the transverse groove, driving the limiting block to move synchronously in the limiting groove, ensuring the smoothness and linearity of the cutting mechanism's movement; the cutting mechanism can be easily operated from outside the mold through the handle and the pulling block, realizing flexible adjustment of different positions, while keeping the operator away from the high-temperature extrusion zone and the cutting zone, improving operational safety.

[0012] Furthermore, the width of the sliding block is adapted to the vertical groove, and the sliding block slides in the vertical groove.

[0013] By adopting the above technical solution, the width of the sliding block matches the vertical groove, so that when the sliding block slides to the corresponding vertical groove position, it can be embedded in the vertical groove to achieve axial positioning, prevent axial movement during the cutting process, ensure the accuracy of the cutting position, and thus ensure the uniformity of the length of the insulation pipe product.

[0014] Furthermore, a metal heating wire is installed between the two opposing sliding blocks.

[0015] By adopting the above technical solution, the metal heating wire generates high temperature after being energized, which can melt the insulation tube instantly, completing a clean and fast cutting operation with a smooth cut that requires no further processing, resulting in high efficiency and no dust pollution.

[0016] Furthermore, the upper side of the horizontal groove is provided with a size scale above each vertical groove.

[0017] By adopting the above technical solution, the size scale provides operators with an intuitive length reference, which facilitates quick and accurate adjustment of the sliding block to the vertical groove position corresponding to the required cutting length, greatly improving adjustment efficiency and cutting accuracy, and is conducive to the standardization of length specifications in mass production.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. This utility model, through the setting of the limiting mechanism, forms a three-dimensional guiding and limiting system with the horizontal groove, the limiting groove and the vertical groove together. The horizontal groove realizes the horizontal movement guidance, the limiting groove prevents the cutting mechanism from deviating in the vertical direction, and the multiple vertical grooves enable the cutting mechanism to be accurately positioned at different work positions along the mold axis, thereby realizing fixed-length cutting of different lengths. The structure is compact and easy to adjust.

[0020] 2. This utility model, through the setting of the cutting mechanism, allows for convenient operation from outside the mold via a handle and a pull block, enabling flexible adjustment to different positions. Simultaneously, it keeps operators away from the high-temperature extrusion and cutting areas, improving operational safety. Furthermore, the width of the sliding block matches the vertical groove, allowing it to embed into the groove for axial positioning when it slides to the corresponding position, preventing axial movement during cutting and ensuring accurate cutting position. This guarantees the uniformity of the insulation pipe product length. The metal heating wire generates high temperature upon energization, instantly melting the insulation pipe and completing a clean and rapid cutting operation. The cut is smooth and requires no further processing, resulting in high efficiency and no dust pollution.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] Reference Figures 1-4This utility model embodiment proposes a cutting device for producing thermal insulation materials, including a mold 100. The mold 100 has multiple inlets and outlets on both sides. The inlets of the mold 100 are connected to an extruder 200, which is an SJ-65 thermoplastic material extruder. Each inlet is equipped with a branch feed pipe 101. A main pipe 102 is integrally formed at one end of the branch feed pipe 101 towards the extruder 200, and the main pipe 102 is connected to the extruder 200. The other end of the branch feed pipe 101 extends towards the outlet of the mold 100. By setting multiple inlets and outlets and connecting them to the extruder 200, multiple thermal insulation pipes can be extruded at once. To improve production efficiency, reduce equipment space occupation, and avoid the problem of inconsistent finished product length caused by equipment errors in multiple independent production lines, the cutting mechanism 300 is built into the mold 100, effectively avoiding the safety hazards caused by exposure. The integrated molding structure of the branch feed pipe 101 and the main pipe 102 can evenly distribute the molten insulation material extruded by the extruder 200 into multiple branch feed pipes 101, ensuring that the material flow rate and pressure at each outlet are consistent, thereby ensuring that the produced insulation pipes are consistent in size and uniform in quality. At the same time, the interior of the mold 100 is equipped with a circulating cooling system, such as water cooling or vacuum cooling, in the channel wall of the branch feed pipe 101, which facilitates rapid cooling and molding of the pipe.

[0030] Reference Figures 1-4 The mold 100 is equipped with a cutting mechanism 300 inside. The cutting mechanism 300 is installed in the mold 100 through a limiting mechanism 400. The limiting mechanism 400 includes horizontal grooves 401 on both sides of the mold 100, which are interconnected. A limiting groove 402 is provided on the lower side of the horizontal grooves 401 on the upper surface of the mold 100. Multiple vertical grooves 403 are provided on both sides of the mold 100 of the diversion feed pipe 101. The multiple vertical grooves 403 are equidistantly distributed axially. The vertical grooves 403 are connected to the horizontal grooves 401 and the outside. The horizontal grooves 401, the limiting grooves 402 and the vertical grooves 403 together form a three-dimensional guiding and limiting system. The horizontal grooves 401 realize horizontal movement guidance, the limiting grooves 402 prevent the cutting mechanism 300 from deviating in the vertical direction, and the multiple vertical grooves 403 enable the cutting mechanism 300 to be accurately positioned at different work positions along the axial direction of the mold 100, thereby realizing fixed-length cutting of different lengths. The structure is compact and easy to adjust.

[0031] Reference Figures 1-4The cutting mechanism 300 includes a sliding block 301 that slides in a transverse groove 401. A limiting block 302 is fixed to the bottom of the sliding block 301. The limiting block 302 slides in the limiting groove 402. A pulling block 303 is fixed to the outward side of the sliding block 301. A handle 304 is fixed to the pulling block 303. The sliding of the sliding block 301 in the transverse groove 401 drives the limiting block 302 to move synchronously in the limiting groove 402, ensuring the smoothness and linearity of the movement of the cutting mechanism 300. The handle 304 and the pulling block 303 allow for convenient movement from the mold 100. The external operating cutting mechanism 300 allows for flexible adjustment to different positions, while keeping operators away from the high-temperature extrusion and cutting areas, thus improving operational safety. The width of the sliding block 301 is adapted to the vertical groove 403. The sliding block 301 slides in the vertical groove 403, and the width of the sliding block 301 matches the vertical groove 403, so that when the sliding block 301 slides to the corresponding position of the vertical groove 403, it can be embedded in the vertical groove 403 to achieve axial positioning, preventing axial movement during the cutting process, ensuring the accuracy of the cutting position, and thus ensuring the uniformity of the length of the insulation pipe product.

[0032] Reference Figures 1-4 A metal heating wire 3011 is installed between the two opposing sliding blocks 301. The metal heating wire 3011 generates high temperature after being energized, which can melt the insulation tube instantly to complete a clean and fast cutting operation. The cut is flat and requires no further processing. It is highly efficient and free from dust pollution. The outer end face of the sliding block 301 is provided with a copper conductive terminal, which is connected to the metal heating wire 3011 through a high-temperature resistant wire.

[0033] Reference Figures 1-4 The upper side of the horizontal groove 401 is provided with a size scale above each vertical groove 403. The size scale provides the operator with an intuitive length reference, which makes it easy to quickly and accurately adjust the sliding block 301 to the position of the vertical groove 403 corresponding to the required cutting length. This greatly improves the adjustment efficiency and cutting accuracy, and is conducive to the uniformity of length specifications in mass production.

[0034] The specific implementation method is as follows: During operation, the operator first pulls the pulling block 303 according to the target length of the insulation pipe through the external handle 304 of the mold 100, which drives the sliding block 301 to slide along the horizontal groove 401. The limiting block 302 moves simultaneously in the limiting groove 402 to ensure stability. Referring to the size scale corresponding to the vertical groove 403 on the upper side of the horizontal groove 401, the sliding block 301 is adjusted to the front of the target position and waits to be embedded in the vertical groove 403. At the same time, the metal heating wire 3011 is energized and heated to the target temperature, and then the operation is started. The extruder 200 delivers molten soft foam raw material to the main pipe 102, which then distributes it evenly to multiple channels via an integrally formed branch feed pipe 101. The raw material flows along the branch feed pipe 101 towards the discharge port of the mold 100, where it cools and solidifies into a continuous tube preform within the forming cavity. The extrusion rate of the extruder 200 is fixed. After the extrusion time and speed are pre-set, the extruder 200 pauses at the set extrusion duration. At this point, the sliding block 301 is slid by the handle 304, allowing the sliding block to slide... Block 301 slides downwards along the vertical groove 403 of the target length, and then cuts the pipe through the metal heating wire 3011. After cutting, it slides upwards again along the vertical groove 403. At this time, the integrity of the cut is not damaged by the limit of the vertical groove 403. This ensures that the multi-channel cutting mechanism 300 operates synchronously and ensures consistent length. During cutting, the sliding block 301 is fixed by the limit of the vertical groove 403. The cut finished product is output synchronously from multiple outlets and can be directly packaged. The extruder 200 stops and then resumes feeding. While feeding, the cut pipe is pushed towards the outlet. This cycle continues. In the whole process, the diversion feeding system and the extruder 200 work together to solve the problem of large footprint for single-piece processing. The limiting mechanism 400 and the cutting mechanism 300 work together to ensure cutting accuracy. The built-in cutting mechanism 300 improves safety. The metal heating wire 3011 adapts to the characteristics of the pipe to ensure the quality of the cut. Finally, it realizes the synchronous production of multiple pipes in a single device, efficient and safe operation, greatly improving efficiency and greatly reducing the footprint.
