Description

Technical Field

[0001] This utility model relates to a traction sawing machine for nylon thermal insulation strips, belonging to the technical field of nylon thermal insulation strip processing equipment. Background Technology

[0002] The current process for nylon thermal insulation strip extrusion production lines involves an extruder equipped with a dedicated die. The product extruded from the die is the finished nylon thermal insulation strip. A 6-meter-long material rack can be directly attached behind the die for simple production. After extrusion, the nylon thermal insulation strip needs to be sawed. Existing technology "Application No.: CN2022207323189" discloses a servo-driven traction sawing machine. Through the alternating traction of traction module A and traction module B, all nylon thermal insulation strips extruded from the die maintain the same length, avoiding waste caused by inconsistent lengths during sawing. Furthermore, the cyclic traction formed by traction module A and traction module B achieves uninterrupted traction, greatly improving traction efficiency.

[0003] However, the existing technology has the following drawbacks: 1. Both traction module A and traction module B are single-row structures, which can only traction one row of nylon heat insulation strips at a time. This not only results in low working efficiency, but also, since the extrusion dies of existing nylon heat insulation strip extruders are multi-layer structures, they can extrude multiple layers of nylon heat insulation strips at a time. Therefore, when using the above-mentioned traction sawing machine for traction, a single-layer extrusion die must be installed in the extruder. This requires additional design and development of a single-layer extrusion die, resulting in high production costs; 2. The height of the traction module and the sawing mechanism cannot be adjusted according to the discharge height of the front-end nylon heat insulation strip extruder. When the discharge height of the extruder and the height of the traction module and the sawing mechanism are not on the same horizontal line, it is difficult to guarantee the traction quality.

[0004] Therefore, the research objective of this utility model is to provide a nylon heat insulation strip traction sawing machine that has high working efficiency, can adapt to multi-layer extrusion molds, and is easy to adjust the height of the traction module and sawing mechanism. Utility Model Content

[0005] To address the shortcomings of the aforementioned technologies, this utility model provides a traction sawing machine for nylon heat insulation strips. Through two sets of multi-layer traction modules, multiple rows of nylon heat insulation strips are alternately and cyclically tractioned. This not only maintains the same length of the nylon heat insulation strips and improves traction efficiency, but also significantly enhances work efficiency. Simultaneously, an electric screw jack is used to adjust the height of the traction modules and sawing mechanism, ensuring that they are level with the extruder's discharge height, thereby improving traction quality.

[0006] To solve the problems of the existing technology, the technical solution adopted by this utility model is as follows:

The top inner side of the gantry frame also has two sets of lifting cylinders for driving the lifting base to rise and fall, as well as encoder rollers that can swing up and down.

[0010] Furthermore, the optical axis assembly includes several sets of optical axes, stop bars, several sets of front layering rods, and several sets of rear layering rods.

[0011] Furthermore, the anti-slip partition is provided in three or five groups from bottom to top, and the number of groups of the front layer bar and the rear layer bar is consistent with the number of groups of the anti-slip partition.

[0012] Furthermore, the end of the lifting frame away from the sawing mechanism is provided with a vertically upward support frame, and the inner side of the support frame is provided with two sets of adjustable front top plates.

[0013] Furthermore, the chassis is equipped with wheels at the four corners of its bottom.

Detailed Implementation

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the following description is provided in conjunction with the appendix. Figure 1-7 Further analysis of this utility model is then conducted.

[0024] like Figure 1-7As shown, a traction sawing machine for nylon heat insulation strips is characterized by comprising a chassis 10, a lifting frame 20, a sliding base 30, a first traction module 40, a second traction module 50, and a sawing mechanism 60. The lifting frame 20 is located above the chassis 10 and is connected to the chassis 10 via an electric screw jack 70 for driving the lifting frame 20 to rise and fall. The sliding base 30 is fixedly located on the top of the lifting frame 20. The first traction module 40 and the second traction module 50 are slidably located on the top of the sliding base 30 via a slide rail slider. The bottom of the first traction module 40 is connected to a first traction motor 80 that drives it to slide via a screw drive. The bottom of the second traction module 50 is connected to a second traction motor 90 that drives it to slide via a screw drive. The first traction module 40 and the second traction module 50 respectively include a base plate 401 and a sliding plate 402. The bottom plate 401 has three sets of vertically arranged columns 404 at its two ends. The two ends of the sliding plate 402 are respectively mounted on the columns 404 via linear bearings. The two ends of the top plate 403 are fixed to the top of the columns 404. The bottom of the top plate 403 has several sets of pressure cylinders 405 for driving the sliding plate 402 to rise and fall. Between every two sets of columns 404, there are several sets of anti-slip partitions 406 arranged from bottom to top. The anti-slip partitions 406 are located between the bottom plate 401 and the sliding plate 402. The anti-slip partitions 406 are used to separate each row of nylon heat insulation strips. During traction, the sliding plate 402 is driven to fall by the pressure cylinders 405, which applies pressure to the nylon heat insulation strips and the anti-slip partitions 406, clamping the nylon heat insulation strips and pulling them toward the sawing mechanism 60. The sawing mechanism 60 is located at the end of the lifting frame 20 away from the first traction module 40.

[0025] In this embodiment, preferably, the first traction module 40 and the second traction module 50 are also provided with two sets of adjustable clamping slide rods 407 at one end away from the sawing mechanism 60. The clamping slide rods 407 are used to limit the two sides of the nylon heat insulation strip to ensure that the nylon heat insulation strip enters the first traction module 40 and the second traction module 50 in an orderly manner.

[0026] In this embodiment, preferably, the sawing mechanism 60 includes a gantry bracket 601, a lifting base 602, a saw blade 603, a saw blade motor 604, and an optical axis assembly 605. The gantry bracket 601 has a front baffle 606 at one end near the second traction module 50. The front baffle 606 prevents sawdust generated during sawing from falling onto the saw blade motor 604 and damaging the transmission mechanism between the saw blade motor 604 and the saw blade 603. A support plate 607 is provided on the top of the front baffle 606, providing support for the bottom row of nylon heat insulation strips. The lifting base 602 is vertically and flexibly mounted inside the gantry bracket 601 via a sliding rail slider. The saw blade 603 is mounted on the lifting base 602 away from the front baffle 606 via a rotating shaft. The saw blade motor 604 is located inside the lifting base 602 and is connected to the rotating shaft of the saw blade 603 via a synchronous pulley to drive the saw blade 603 to rotate. The optical shaft assembly 605 is located above the saw blade 603. The inner top of the gantry bracket 601 is also provided with two sets of lifting cylinders 608 for driving the lifting base 602 to rise and fall, as well as encoder rollers 609 that can swing up and down. The encoder rollers 609 are in contact with the top row of nylon heat insulation strips to facilitate the collection and uploading of the movement data of the nylon heat insulation strips to the encoder.

[0027] In this embodiment, preferably, the optical axis assembly 605 includes several sets of optical axes 6051, baffles 6052, several sets of front layering rods 6053, and several sets of rear layering rods 6054. The optical axes 6051 are laterally fixed inside the gantry bracket 601 and located above the saw blade 603. Two sets of baffles 6052 are provided, slidably mounted on the optical axes 6051. Several sets of sliding cylinders 6055 connect one set of baffles 6052 to the side plate of the gantry bracket 601 to drive that set of baffles 6052 to slide, adjusting the interval between the two sets of baffles 6052, limiting the two sides of the nylon heat insulation strip, and ensuring that the nylon heat insulation strip is neatly arranged. The strip is sawn, and the front and rear ends of the other set of baffles 6052 are respectively provided with swing shafts 6056. One end of several sets of front layering rods 6053 is swingably mounted on the swing shafts 6056 at the front end of the baffles 6052. By adjusting the swing angle of the front layering rods 6053, the distance between the front layering rods 6053 and the second traction module 50 can be adjusted so as to better support the nylon heat insulation strips pulled by the second traction module 50. One end of several sets of rear layering rods 6054 is swingably mounted on the swing shafts 6056 at the rear end of the baffles 6052. The front layering rods 6053 and rear layering rods 6054 have the same function as the anti-slip partition 406, which is used to separate each row of nylon heat insulation strips and provide support for the nylon heat insulation strips.

[0028] In this embodiment, preferably, the anti-slip partition 406 is arranged in three or five groups from bottom to top, and the number of groups of the front layer rod 6053 and the rear layer rod 6054 is consistent with the number of groups of the anti-slip partition 406.

[0029] In this embodiment, preferably, the end of the lifting frame 20 away from the sawing mechanism 60 is provided with a vertically upward support frame 201, and the inner side of the support frame 201 is provided with two sets of adjustable front top plates 202. The front top plates 202 are used to provide limiting and support for the nylon heat insulation strip before entering the first traction module 40.

[0030] In this embodiment, preferably, the chassis 10 is provided with four wheels 101 at the bottom corners.

[0031] The working principle of this utility model is as follows: First, the traction sawing machine is placed in front of the output port of the nylon heat insulation strip extruder. Initially, the front end of each row of nylon heat insulation strips is manually passed from bottom to top through the anti-slip partition 406 of the first traction module 40 and the second traction module 50, and then pressed by the pressing cylinder 405. During traction, the first traction module 40 is located at the end closest to the upright 201. First, the first traction module 40 presses the nylon heat insulation strip and pulls it towards the second traction module 50. At this time, the second traction module 50 is located at the end closest to the first traction module 40 and releases the nylon heat insulation strip. After the first traction module 40 pulls the nylon heat insulation strip into place, the second traction module 50 takes over the nylon heat insulation strip pulled by the first traction module 40 and clamps it, pulling it towards the sawing mechanism 60. Simultaneously, the first traction module 40 releases the nylon heat insulation strip and moves back. After the second traction module 50 pulls the nylon heat insulation strip into place, the first traction module 40 clamps the subsequent nylon heat insulation strips from the origin and pulls them towards the second traction module 50. This process is repeated continuously to push the nylon heat insulation strips to the sawing mechanism 60. When the nylon heat insulation strips are pushed to the optical axis assembly 605 of the sawing mechanism 60, the front layering rod 6053 and the rear layering rod 6054 support and limit the vertical movement of each row of nylon heat insulation strips, and the stop bar 6052 limits the horizontal movement of the nylon heat insulation strips. Then, the lifting cylinder 608 drives the lifting base 602 to rise, causing the operating saw blade 603 to rise and saw the nylon heat insulation strips. After sawing is completed, the saw blade 603 descends and resets.
