Description

Technical Field

[0001] This utility model relates to the field of fixed-length cutting machines, and in particular to a fixed-length cutting machine for heat insulation strips. Background Technology

[0002] In the construction and automotive industries, thermal insulation strips are key components for achieving structural thermal insulation. Their production and processing require extremely high length precision. Thermal insulation strip length-cutting machines are specialized equipment designed to precisely cut long thermal insulation strips to a set length. The length-conveying assembly is one of the core functional modules of this machine, primarily responsible for stably and continuously conveying the thermal insulation strip to the cutting area, providing a fundamental guarantee for subsequent precise cutting. Currently, most common length-conveying assemblies on the market employ an upper and lower counter-pressure conveying structure, consisting of an upper belt conveyor and a lower belt conveyor. The friction generated by the synchronous operation of the upper and lower belts drives the thermal insulation strip forward. Combined with the equipment's length measurement system, the conveying distance of the thermal insulation strip is controlled, thus meeting the requirements for length-cutting.

[0003] However, the fixed-length conveying components of traditional thermal insulation strip cutting machines have significant drawbacks in practical applications. Due to potential minor deviations in cross-sectional dimensions and uneven material properties of the thermal insulation strip itself, and the tendency for uneven belt tension and slight asynchrony in conveying speeds in the upper and lower belt conveyors after prolonged use, the thermal insulation strip easily deviates from the preset conveying path during transport, resulting in lateral offset. This offset not only prevents the thermal insulation strip from accurately reaching the designated cutting position on the cutting equipment, causing the length error of the cut thermal insulation strip to exceed the allowable range, but it can also cause the thermal insulation strip to jam in the conveying channel, or even damage the surface structure of the thermal insulation strip, affecting product quality and production efficiency, and bringing additional production costs and quality risks to enterprises.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A thermal insulation strip fixed-length cutting machine includes a base. A fixed-length conveying assembly is fixedly installed on the upper end of the base. The fixed-length conveying assembly consists of an upper belt conveyor and a lower belt conveyor. An adjusting bracket is fixedly installed at the front end of the lower belt conveyor.

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a heat insulation strip fixed-length cutting machine includes a base 1. A fixed-length conveying assembly 2 is fixedly installed on the upper end of the base 1. The fixed-length conveying assembly 2 consists of an upper belt conveyor 3 and a lower belt conveyor 4. An adjusting bracket 5 is fixedly installed at the front end of the lower belt conveyor 4. The adjusting bracket 5 consists of a fixed plate 8, a support plate 9, a bidirectional screw 11, a handle 12, and a guide plate 20. Two fixed plates 8 and two support plates 9 are provided. The two fixed plates 8 are arranged horizontally and symmetrically. The two support plates 9 are respectively fixedly installed at the front ends of the two fixed plates 8. The bidirectional screw 11 is rotatably mounted on the front end of the two fixed plates 8. Mounted on two support plates 9, there are two handles 12, each fixedly installed at both ends of the bidirectional lead screw 11. There are two guide plates 20, each fixedly installed at the upper ends of the two support plates 9. Two blocking and limiting structures 6 are symmetrically installed on the bidirectional lead screw 11 and the two guide plates 20, and the blocking and limiting structures 6 are located between the upper belt conveyor 3 and the lower belt conveyor 4. The blocking and limiting structure 6 consists of a moving block 13, a connecting plate 15, a guide rod 16, a limiting base plate 17, and a rotating roller 19. The connecting plate 15 is fixedly installed on the upper end of the moving block 13, and the guide rod 16 is fixedly installed on the connecting plate 19. At the outer end of the connecting plate 15, the limiting base plate 17 is fixedly installed at the rear end of the connecting plate 15. Several rotating rollers 19 are evenly rotated and installed inside the limiting base plate 17. An adjusting bracket 5 composed of a fixed plate 8, a support plate 9, a bidirectional lead screw 11, a handle 12, and a guide plate 20 is set on the fixed-length conveying assembly 2. A blocking and limiting structure 6 composed of a moving block 13, a connecting plate 15, a guide rod 16, a limiting base plate 17, and rotating rollers 19 is set between the upper belt conveyor 3 and the lower belt conveyor 4. The blocking and limiting structure 6 is located between the upper belt conveyor 3 and the lower belt conveyor 4. The system can limit the heat insulation strip in the middle of the conveying process to prevent it from deviating and ensure that it accurately reaches the cutting position of the cylinder cutting device 7, reducing the probability of cutting length error and jamming. The rotating roller 19 can rotate with the heat insulation strip, thereby reducing the frictional resistance of the blocking and limiting structure 6 to the heat insulation strip, protecting the surface structure of the heat insulation strip, improving product quality and production efficiency, and reducing enterprise production costs and quality risks. The distance between the two blocking and limiting structures 6 can be adjusted by adjusting the bracket 5, thereby adapting to heat insulation strips of different widths and improving the applicability of the blocking and limiting structure 6.

[0016] Specifically, a cylinder cutting device 7 is fixedly installed at the upper end of the equipment base 1 and behind the fixed-length conveying assembly 2. When using this fixed-length insulation strip cutting machine to cut the insulation strip, the insulation strip to be cut is first placed between the upper belt conveyor 3 and the lower belt conveyor 4 of the fixed-length conveying assembly 2. The fixed-length conveying assembly 2 is started, so that the upper belt conveyor 3 and the lower belt conveyor 4 run synchronously. The friction generated by the operation of the upper and lower belts on the upper belt conveyor 3 and the lower belt conveyor 4 drives the insulation strip to be conveyed towards the cylinder cutting device 7. When the fixed-length conveying assembly 2 conveys the insulation strip to the designated position according to the preset cutting length, the fixed-length conveying assembly 2 stops running. Then the cylinder cutting device 7 starts to cut the insulation strip. After the cutting is completed, the cylinder cutting device 7 resets, and the fixed-length conveying assembly 2 starts again to continue conveying the next section of insulation strip to be cut. Repeating the above steps can achieve continuous fixed-length cutting of insulation strips.

[0017] In addition, the fixed-length conveying assembly 2 integrates a length measuring system, which typically consists of components such as an encoder and a counting controller. The encoder can be linked with the drive roller shaft of the upper belt conveyor 3 or the lower belt conveyor 4 to monitor the number of belt rotations in real time and convert the rotation signal into an electrical signal, which is then transmitted to the counting controller. The counting controller accurately calculates the conveying distance of the upper belt conveyor 3 and the lower belt conveyor 4 based on the preset cutting length of the heat insulation strip and the signal fed back by the encoder. When the conveying distance reaches the preset cutting length, the counting controller will send a control signal to stop the operation of the upper belt conveyor 3 and the lower belt conveyor 4, thereby achieving precise control of the conveying distance of the heat insulation strip. This provides data support for the accurate cutting of the subsequent cylinder cutting equipment 7, ensuring that the length of the cut heat insulation strip meets the set requirements.

[0018] Specifically, the fixing plate 8 on the adjusting bracket 5 is fixedly installed at the front end of the lower belt conveyor 4 by bolts. The support plate 9 has mounting holes 10, and the guide plate 20 has guide holes 21. The bidirectional screw 11 is rotatably installed in the two mounting holes 10 on the two support plates 9. The handle 12 is located on the outside of the support plate 9. The moving block 13 on the blocking and limiting structure 6 has screw holes 14. The moving block 13 is installed on the bidirectional screw 11 through the screw holes 14, and the moving block 13 is located on the two support plates on the adjusting bracket 5. Between 9, the connecting plate 15 is located inside the guide plate 20, the guide rod 16 is movably inserted into the guide hole 21, and the limiting plate 17 is located between the upper belt conveyor 3 and the lower belt conveyor 4. Several roller grooves 18 are evenly distributed on the limiting plate 17, penetrating both the inside and outside of the limiting plate 17. A rotating roller 19 is rotatably installed within the roller grooves 18. During the conveying of the heat insulation strip by the upper belt conveyor 3 and the lower belt conveyor 4 of the fixed-length conveying assembly 2, the limiting plate 17 of the blocking limiting structure 6 is always located between the upper belt conveyor 3 and the lower belt conveyor 4. Between the lower belt conveyors 4, the heat insulation strip contacts the rotating roller 19 inside the limiting plate 17 during conveying. The rotating roller 19 rotates within the roller groove 18 as the heat insulation strip moves, thus limiting the heat insulation strip to the left and right and preventing it from shifting during conveying. When it is necessary to adjust the distance between the two blocking limiting structures 6 according to the width of the heat insulation strip, the operator holds the handle 12 of the adjusting bracket 5 and rotates it. The handle 12 drives the bidirectional screw 11 to rotate within the mounting hole 10 of the support plate 9. Since the moving block 13 passes through the screw hole 1... 4. The guide rod 16 of the connecting plate 15 of the moving block 13 is installed on the bidirectional lead screw 11 and is movably inserted into the guide hole 21 of the guide plate 20. When the bidirectional lead screw 11 rotates, it will drive the two moving blocks 13 to move towards or away from each other along the bidirectional lead screw 11. When the moving blocks 13 move, they will drive the limiting plate 17 to move synchronously through the connecting plate 15 until the distance between the rotating rollers 19 on the two blocking limiting structures 6 is matched with the width of the heat insulation strip. Then, stop rotating the handle 12 to complete the adjustment of the distance between the two blocking limiting structures 6.

[0019] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
