DETAILED DESCRIPTION

[0020] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only configured to explain the present invention and are not configured to limit the present invention. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present invention by illustrating examples of the present invention.

[0021] The directional words appearing in the following description are all directions shown in the figures, and do not limit the specific structure of the present invention. In the description of the present invention, it should also be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0022] As attached Figure 1-7 As shown, an adjustable thermal insulation strip cutting device includes a stand. The first guide mechanism 1 is located at the front end of the stand and is responsible for guiding the thermal insulation strip into the cutting device. The feed clamping mechanism 2 follows the first guide mechanism 1 and is responsible for clamping and conveying the thermal insulation strip to the cutting mechanism 3, and the cutting mechanism 3 accurately cuts the thermal insulation strip according to preset parameters. The second guide mechanism 4 and the third guide mechanism 5 following the cutting mechanism 3 are responsible for guiding the cut thermal insulation strip to continue to move forward. The discharging clamping mechanism 6 follows the third guide mechanism 5 and is responsible for clamping and conveying the thermal insulation strip that has been cut to provide traction for it. The third guide mechanism 5 is located at the end of the stand and is responsible for guiding the thermal insulation strip out of the cutting device. A fixed distance measuring mechanism 7 is provided on one side of the fourth guide mechanism 8, which is responsible for measuring the length or spacing of the thermal insulation strip to ensure the accuracy and consistency of cutting.

[0023] The structures of the first guide mechanism 1, the second guide mechanism 4, the third guide mechanism 5 and the fourth guide mechanism 8 are consistent. Taking the first guide mechanism 1 as an example, its structure is described in detail. The first guide mechanism 1 includes a support plate 47 and a guide seat 48, which are fixed to the stand through pillars to provide stable support for the entire guide mechanism. The guide seat 48 is provided with two groups and is installed on the upper end surface of the support plate 47. The two groups of guide seats 48 are arranged oppositely to form a conveying channel for the heat insulation strip. Roller grooves 51 are provided on the opposite surfaces of the two groups of guide seats 48, and several groups of rollers 52 arranged in a straight line are installed in the roller grooves 51. A pressing plate 53 for covering the roller grooves 51 is fixed on the upper end surface of the guide seat 48 to limit the position of the roller 52 in the roller groove 51 and prevent the roller 52 from jumping out of the groove. When the heat insulation strip is conveyed on the first guide mechanism 1, it will be clamped by the two groups of guide seats 48 arranged oppositely, and the roller 52 will roll in the roller groove 51 to achieve smooth and accurate conveying.

[0024] Two first long holes 50 extending in the width direction of the support plate 47 are provided, and threaded holes 49 corresponding to the first long holes 50 are provided at both ends of the length direction of the guide seat 48. Bolts are screwed into the threaded holes 49 of the guide seat 48 and pass through the first long holes 50, thereby fixing the guide seat 48 on the support plate 47. By loosening the bolts and adjusting the positions of the bolts in the first long holes 50, the spacing between the two groups of guide seats 48 can be changed to adapt to heat insulation strips of different specifications.

[0025] A pressing assembly is provided at one end of the support plate 47. The pressing assembly is located between two groups of guide seats 48 and is used to stably press the thermal insulation strip to ensure its stability during cutting or transportation. The pressing assembly includes a pressing seat 56, a support seat 58 and a support frame 54 fixed to the support plate 47. The support seat 58 is installed on one side of the support frame 54 by a fixing bolt. The fixing bolt passes through a second long strip hole 60 preset on the support seat 58, thereby allowing the support seat 58 to be adjusted to a certain extent on the support frame 54. A pressing roller 55 is installed on the lower end surface of the pressing seat 56 for directly contacting and pressing the thermal insulation strip. A guide rod 59 passing through the support seat 58 is fixed on the upper end surface of the pressing seat 56. A limit seat is provided at the end of the guide rod 59 to prevent the guide rod 59 from escaping from the support seat 58. The guide rod 59 is covered with a second spring 57 , which abuts between the support seat 58 and the pressure seat 56 to provide a certain elastic force for the pressure seat 56 , so that the pressure roller 55 can always be in close contact with the heat insulation strip.

[0026] The feed pinching mechanism 2 and the discharge pinching mechanism 6 have the same structure, both comprising upper pinching rollers and lower pinching rollers that are relatively arranged. The structure is a mature technical solution and will not be described in detail here.

[0027] The cutting mechanism 3 is mainly composed of a base 19, a movable base body 20 and a mounting seat 27. The base 19 is provided in two groups and is fixed to the stand at intervals. A vertical plate 21 is installed on the inner side of each group of bases 19, and a second slide rail 25 is fixed on the inner side of each vertical plate 21. Each second slide rail 25 is provided with a slider 32. The movable base body 20 is fixed between the two groups of sliders 32, and a fixed base body 23 is fixed between the two groups of second slide rails 25. The fixed base body 23 is located above the movable base body 20. The mounting seat 27 is slidably connected to one side of the movable base body 20 through a linear guide rail 34. A first rotating shaft 30 is installed on the mounting seat 27. A cutting wheel 22 is fixed to one end of the first rotating shaft 30, and a second synchronous wheel 31 is fixed to the other end of the first rotating shaft 30. A second servo motor 28 is fixed to the outer side of the mounting seat 27 , and a third synchronous wheel 33 is fixed to the output shaft of the second servo motor 28 . The third synchronous wheel 33 is connected to the second synchronous wheel 31 via a second synchronous belt 29 , thereby driving the cutting wheel 22 .

[0028] A first bevel gear 35 is fixed on the first rotating shaft 30, a rack 39 is fixed on the moving seat body 20, and a second rotating shaft 38 is fixed on the inner side surface of the mounting seat 27 through the bearing seat 37. A second bevel gear 36 meshing with the first bevel gear 35 is fixed on one end of the second rotating shaft 38, and a spur gear 40 meshing with the rack 39 is fixed on the other end of the second rotating shaft 38. When the second servo motor 28 drives the first rotating shaft 30 to rotate, the first bevel gear 35 rotates accordingly, and the power is transmitted to the spur gear 40 meshing with the rack 39 on the second rotating shaft 38 through the second bevel gear 36 meshing therewith, providing the mounting seat 27 with power to slide along the moving seat body 20. Driven by the second servo motor 28, the cutting wheel 22 can not only realize the rotation action, but also slide along the moving seat body 20 driven by the mounting seat 27, thereby realizing the cutting operation of the thermal insulation strip. The bottom of the movable seat body 20 is provided with a through hole 42 extending toward the top thereof, so as to leave enough escape space for the lifting and lowering of the first rotating shaft 30 without being hindered by the movable seat body 20 .

[0029] Two sets of guide shafts 24 passing through the fixed seat body 23 are fixed to the upper end surface of the movable seat body 20. The guide shafts 24 are covered with a first spring 26, and the first spring 26 abuts between the fixed seat body 23 and the movable seat body 20. When the movable seat body 20 rises, the first spring 26 is compressed and stores energy. When the thermal insulation strip is cut, the second servo motor 28 stops and no longer provides power for the movable seat body 20 to rise. At this time, the first spring 26 begins to release the previously stored energy, pushing the movable seat body 20 to move downward along the second slide rail 25 until it returns to the initial position.

[0030] The inner side of the base 19 is provided with an arc-shaped guide groove 41, and the outer side of the base 19 is provided with two sets of second positioning holes 46 connected to the guide groove 41. A fan-shaped plate 43 is fixed to one side of the bottom of the vertical plate 21, and a curved guide strip 44 is provided on the side of the fan-shaped plate 43 facing the base 19. The guide strip 44 is embedded in the guide groove 41, and the end surface of the guide strip 44 is provided with a first positioning hole 45 adapted to the second positioning hole 46. The fastening bolt passes through the second positioning hole 46 and is screwed into the first positioning hole 45 to complete the locking of the vertical plate 21.

[0031] The positions of the two second positioning holes 46 correspond to the 90° angle (the angle with the end face of the stage) and the 45° angle of the cutting wheel 22. When the angle of the cutting wheel 22 needs to be adjusted (from the 90° angle to the 45° angle), loosen the fastening bolts, pull the vertical plate 21, and move the guide strip 44 of the sector plate 43 along the arc track of the guide groove 41 until the first positioning hole 45 is aligned with the second positioning hole 46 corresponding to the 45° angle, and then tighten the fastening bolts to complete the adjustment of the position of the cutting wheel 22.

[0032] The fixed distance measuring mechanism 7 includes a base plate 9, which is mounted on the upper end surface of the platform through a support. First synchronous wheels 12 are installed at both ends of the upper end surface of the base plate 9, and two groups of first synchronous wheels 12 are connected by a first synchronous belt 17. A first servo motor 16 fixedly connected to one of the first synchronous wheels 12 is installed at one end of the lower end surface of the base plate 9. A first slide rail 10 fixed to the base plate 9 is arranged between the two groups of first synchronous wheels 12, and a slide seat 13 is arranged on the first slide rail 10, and the slide seat 13 is fixedly connected to the first synchronous belt 17. A support plate 14 is fixed to the upper end surface of the slide seat 13, and a laser displacement sensor 15 suspended above the fourth guide mechanism 8 is installed at one end of the support plate 14. A sensing sheet 18 is arranged on one side of the slide seat 13, and a slot-type photoelectric sensor 11 corresponding to the sensing sheet 18 is arranged on both ends of one side of the base plate 9. The two groups of slot-shaped photoelectric sensors 11 correspond to the two limit positions of the slide 13 respectively, representing the maximum and minimum distances that the slide 13 can move, so as to ensure that it does not exceed the predetermined range of motion.

[0033] The first servo motor 16 provides driving power, and by precisely controlling its rotation speed and direction, the slide 13 can be placed on the first slide rail 10. When the first servo motor 16 is started, it drives the first synchronous wheel 12 connected thereto to rotate, and the rotating first synchronous wheel 12 transmits power to another set of first synchronous wheels 12 through the first synchronous belt 17, so that they rotate synchronously, and the slide 13 fixedly connected to the first synchronous belt 17 moves smoothly along the first slide rail 10, and the laser displacement sensor 15 suspended at one end of the support plate 14 moves with the movement of the slide 13, so as to achieve fixed distance measurement of the thermal insulation strip.

[0034] When a new thermal insulation strip (i.e., the thermal insulation strip to be cut) is about to reach the cutting position, if the laser displacement sensor 15 suddenly detects a significant change in position height (due to the sudden appearance of the thermal insulation strip), this means that the new thermal insulation strip is in place. The feed clamping mechanism 2 and the discharge clamping mechanism 6 will immediately stop and stop the delivery of the thermal insulation strip. In the stopped state, the cutting mechanism 3 will quickly and accurately complete the cutting operation of the thermal insulation strip. After the cutting is completed, the feed clamping mechanism 2 and the discharge clamping mechanism 6 will start again to send out the cut thermal insulation strip and send in the new thermal insulation strip to be cut. Since there is a gap between the cut thermal insulation strip and the thermal insulation strip to be cut, when the laser displacement sensor 15 detects a significant change in position height again (this time because the head of the next thermal insulation strip reaches below the sensor), this indicates that the next thermal insulation strip is in place and is ready to enter the next cutting process.

[0035] According to the embodiments of the present invention as described above, these embodiments do not describe all the details in detail, nor do they limit the invention to specific embodiments. Obviously, many modifications and changes can be made based on the above description. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can make good use of the present invention and the modified use based on the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
