Description

Technical Field

[0001] This utility model relates to the technical field of thermal insulation strip cutting equipment, and in particular to a precision thermal insulation strip cutting machine. Background Technology

[0002] Thermally broken aluminum alloy doors and windows are a new type of door and window, mainly consisting of thermal break strips and inner and outer aluminum profile frames. The thermal break strips separate and tightly connect the inner and outer aluminum profile frames to form a whole. Its thermal insulation performance is at the same level as that of plastic (steel) windows—the national standard level, which completely solves the fatal problem of aluminum alloys conducting heat quickly and failing to meet energy-saving requirements.

[0003] During the production of thermal insulation strips, raw material granules are fed into a hot melt extruder and continuously extruded according to the shape of the extruder head. Then, a cutting device cuts the continuous thermal insulation strips into long strips of a certain length for easy transportation. Finally, they are sawn into short strips of the corresponding specifications according to the door and window specifications.

[0004] After the extruder continuously extrudes the insulation strip to a certain length, it is cut by the cutting machine from both ends to form long strips of similar length. In order to improve production efficiency, the extruder usually extrudes multiple insulation strips at the same time. However, due to the long distance between the cutting saws at both ends of the cutting device, when the insulation strip reaches the cutting saw at the rear end, some insulation strips may be bent or stacked during the transmission process. This will result in a large difference in the cut length of the insulation strips in the same batch, affecting the processing accuracy. Utility Model Content

[0005] The purpose of this invention is to provide a precision cutting machine for thermal insulation strips, aiming to solve the problem of large discrepancies in cutting precision for thermal insulation strips of the same batch by existing cutting devices.

[0006] To achieve the above objectives, this utility model provides a precision heat insulation strip cutting machine, including a frame, on which a cutting component and a guiding component are mounted. The cutting component is used to cut the heat insulation strip, and the guiding component is used to guide the heat insulation strip. In the conveying direction of the heat insulation strip, the end of the frame that first contacts the heat insulation strip is designated as the front end of the frame. A compaction component is provided at the front end of the frame. The compaction component includes a guide plate, a swing rod, a pressure rod, and a clamping spring.

[0008] Furthermore, a scrap section is provided on the frame, located directly below the drawing assembly.

[0009] Furthermore, a set of cutting components is provided at both the front and rear ends of the frame. Each set of cutting components includes a lifting saw, a clamping cylinder, and a pressure plate.

[0034] The present invention will be described in detail below with reference to specific embodiments.

[0035] In this utility model, unless otherwise explicitly specified and limited, when terms such as "set in," "connected," or "linked" appear, these terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or a connection through one or more intermediate media. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The directional terms appearing in this utility model are for the purpose of better describing the characteristics of the features and the relationships between them. It should be understood that when the placement direction of this utility model changes, the direction of the characteristics of the features and the relationships between them also changes accordingly. Therefore, directional terms do not constitute an absolute limitation on the characteristics of the features and the relationships between them in space, but only a relative limitation.

[0036] like Figures 1 to 9 As shown, this utility model provides a precision cutting heat insulation strip cutting machine, including a frame 1. The frame 1 is equipped with a cutting component 2 and a guiding component 3. The cutting component 2 is used to cut the heat insulation strip, and the guiding component 3 is used to guide the heat insulation strip. In the conveying direction of the heat insulation strip, the end of the frame 1 that first contacts the heat insulation strip is designated as the front end of the frame 1. The front end of the frame 1 is equipped with a compaction component 4. The compaction component 4 includes a guide plate 40, a swing rod 41, a pressure rod 42, and a compression spring 43. The guide plate 40 is mounted on the frame 1. One end of the swing rod 41 is hinged to the frame 1, and the other end of the swing rod 41 is hinged to the pressure rod 42. The guide plate 40 is provided with an arc groove 44, and the pressure rod 42 can slide in the arc groove 44. One end of the compression spring 43 is mounted on the frame 1, and the other end of the compression spring 43 is rotatably connected to the swing rod 41.

[0037] During the process of extruding the heat insulation strip from the extruder to the appropriate length for cutting, multiple sets of heat insulation strips inevitably bend or stack during movement. Stacked or bent heat insulation strips will inevitably affect the cutting accuracy. With the above design scheme, when the heat insulation strip enters the cutting machine, under its own weight and the action of the clamping spring 43, the pressure rod 42 will flatten the stacked heat insulation strips, so that there is only one layer of heat insulation strip on the frame 1. This avoids the heat insulation strip stacking, which would cause a large difference in the accuracy of heat insulation strips in the same batch and affect the production accuracy.

[0038] In this embodiment, a pulling assembly 5 is provided at the end of the frame 1. The pulling assembly 5 includes a power guide rail 50, a sliding seat 51, a clamping cylinder 52, and a pressure plate 53. The power guide rail 50 is mounted on the frame 1, and the sliding seat 51 is mounted on the power guide rail 50 and can slide on the power guide rail 50. The clamping cylinder 52 is mounted on the sliding seat 51 and is used to drive the pressure plate 53 to move closer to or away from the sliding seat 51. The sliding seat 51 is provided with a clamping part 54, which is located directly above the pressure plate 53.

[0039] With the above design scheme, when the heat insulation strip is guided by the guide component 3 to the pull-out component 5, the clamping cylinder 52 drives the pressure plate 53 to slowly descend until multiple heat insulation strips are clamped. The clamping cylinder 52 can accurately control the clamping force to avoid excessive clamping force from damaging the heat insulation strip. After the heat insulation strip is clamped, the power guide rail 50 will drive the sliding seat 51 to slide backward, so that the bent heat insulation strip is straightened.

[0040] In this embodiment, a waste section 6 is provided on the frame 1, and the waste section 6 is located directly below the drawing assembly 5.

[0041] With the above design scheme, after the pulling component 5 straightens the heat insulation strip, the cutting component 2 is activated and cuts the straightened heat insulation strip. After the heat insulation strip is cut, some waste will continue to be clamped in the pulling component 5. As the power guide rail 50 continues to move, the waste is transported to the waste section 6. The staff only needs to place the trash can or waste box into the waste section 6. When the clamping cylinder 52 drives the pressure plate 53 away from the clamping part 54, the unrestricted waste will automatically fall into the waste section 6 under the action of gravity.

[0042] In this embodiment, a set of cutting components 2 is provided at both the front and rear ends of the frame 1. Each set of cutting components 2 includes a lifting saw 22, a clamping cylinder 20 and a pressure plate 21. The lifting saw 22 is installed on the frame 1, and the clamping cylinder 20 is installed on the frame 1 directly above the lifting saw 22. A pressure plate 21 is provided at the bottom of the clamping cylinder 20.

[0043] In this embodiment, the lifting saw 22 includes a slide plate 222, a lateral drive 221, a lifting drive 223, and a cutting saw 220. The lateral drive 221 is mounted on the slide plate 222 and is used to drive the slide plate 222 to slide on the frame 1. The lifting drive 223 is mounted on the slide plate 222 and is used to drive the cutting saw 220 to rise or fall.

[0044] With the above design scheme, when cutting is required, the clamping cylinder 20 drives the pressing plate 21 to descend, pressing the heat insulation strip onto the frame 1. Then, the lifting drive 223 controls the cutting saw 220 to rise, and at the same time, the lateral drive 221 drives the cutting saw 220 to slide laterally through the slide plate 222, cutting the pressed heat insulation strip.

[0045] In this embodiment, the guide assembly 3 includes a suspension 30, a discharge cylinder 31, a discharge frame 32, an adjusting clamp 34, an adjusting cylinder 33, and a fixed clamp 35. The suspension 30 is fixedly installed on the frame 1, the discharge frame 32 is slidably installed on the bottom of the suspension 30, the discharge cylinder 31 is fixedly installed on the suspension 30, and the discharge cylinder 31 is used to drive the discharge frame 32 to slide on the suspension 30; the adjusting clamp 34 is installed on the discharge frame 32 through the adjusting cylinder 33, and the fixed clamp 35 is installed on the side of the discharge frame 32 away from the adjusting cylinder 33.

[0046] With the above design, after the heat insulation strip is cut, the discharge cylinder 31 is activated, pushing the adjusting clamp 34 and the fixed clamp 35 out of the frame 1. During this process, the clamping cylinder 20 controls the pressing plate 21 to lift, releasing the pressed heat insulation strip. The cut heat insulation strip will fall off the frame 1 under the push of the adjusting clamp 34, avoiding any impact on subsequent processing. The adjusting cylinder 33 can adjust the position of the adjusting clamp 34, making the adjusting clamp 34 closer to or further away from the fixed clamp 35.

[0047] In this embodiment, a base 7 is provided at the bottom of the frame 1, and the frame 1 can slide on the base 7.

[0048] In this embodiment, a pulley assembly 8 is provided between the frame 1 and the base 7. The pulley assembly 8 includes a limiting guide rail 80, limiting pulleys 81, limiting sliders 83, and limiting slide rail 82. The limiting guide rail 80 is fixedly installed on the base 7. Multiple sets of limiting pulleys 81 are evenly installed on the bottom of the frame 1, and the limiting pulleys 81 can slide on the limiting guide rail 80. The limiting slide rail 82 is installed on the base 7, and the limiting slider 83 is installed on the bottom of the frame 1, and the limiting slider 83 can slide on the limiting slide rail 82.

[0049] When the length of the heat insulation strip reaches the cutting requirement, the heat insulation strip will continue to be extruded from the extruder while it is being sawed because the extruder cannot be stopped. With the above design, when the heat insulation strip needs to be sawed, the clamping drive drives the clamping plate 21 to descend and clamp the heat insulation strip. At the same time, the frame 1 begins to move slowly on the base 7. The moving speed of the frame 1 is consistent with the extrusion speed of the extruder, ensuring that the heat insulation strip always remains in a relaxed state during the sawing process, and avoiding the accumulation of continuously extruded heat insulation strip between the fixed sawing component and the extruder, which would affect the production quality.

[0050] Through the above design scheme, the limiting guide rail 80 and the limiting pulley 81 cooperate to ensure that the frame 1 can only slide along the direction of the limiting guide rail 80, and avoid the sliding direction of the frame 1 from deviating; the limiting slider 83 and the limiting slide rail 82 cooperate to limit the sliding distance between the frame 1 and the base 7, and prevent the frame 1 from sliding off the base 7.

[0051] In this embodiment, a stepper motor is installed inside the limiting pulley 81.

[0052] The present invention provides a precision cutting heat insulation strip cutting machine. Compared with the prior art, when the heat insulation strip extruded by the extruder enters the cutting equipment, the compaction component 4 will lay the heat insulation strip flat on the frame 1 under the action of gravity and the compression spring 43, so as to avoid the heat insulation strip from stacking during the movement. The pulling component 5 at the end of the frame 1 will straighten the heat insulation strip, so that multiple sets of heat insulation strips are in a taut state, ensuring that the length of the heat insulation strip is more uniform when cutting.

[0053] Where there is no conflict, the above embodiments and features can be combined with each other.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
