[0001] The utility model relates to the technical field of nylon heat insulation strip processing equipment, in particular to a fixed-length cutting device for producing nylon heat insulation strips. Background Art

[0002] The insulation strip is the core component of the through-strip insulation profile. It is not only a "broken bridge" for heat transfer in the aluminum profile, reducing the heat transfer in the aluminum profile, but also a structural connector for the aluminum profiles on both sides of the insulation profile. Through its connection, the three parts of the insulation profile become a whole and bear the load together. At present, the building energy-saving insulation aluminum profile generally adopts the heat-breaking cold bridge technology to achieve the purpose of heat insulation and energy saving. The nylon insulation strip as the heat-breaking cold bridge is connected in the middle of the inner and outer aluminum alloy frames. It must not only be an excellent insulation material, but also its strength and anti-aging performance must meet the requirements of aluminum alloy doors and windows.

However, this method requires users to manually load and unload materials, and the level of automation is low. Although two sets of cutting devices are set, two workers are still required to operate them, resulting in high labor demand and low production efficiency, which cannot meet the production needs of enterprises. For this reason, we propose a fixed-length cutting device for the production of nylon insulation strips to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Reference Figure 1-6 , a fixed-length cutting device for producing nylon insulation strips, comprising a workbench 1, and also comprising:

[0026] A feeding assembly is arranged on a workbench 1, wherein a slide groove 2 is provided on the upper surface of the workbench 1, and a positioning block 3 is slidably connected in the slide groove 2, and a fixing bolt 4 is threadedly connected to the positioning block 3;

[0027] A cutting assembly is arranged between the feeding assembly and the positioning block 3, the cutting assembly comprises a support frame 5 fixedly connected to the workbench 1, a tool holder assembly is slidably connected to the support frame 5, an electric push rod 6 is also fixedly connected to the support frame 5, the lower end of the electric push rod 6 is slidably connected to the tool holder assembly, the tool holder assembly can only slide in the horizontal direction relative to the electric push rod 6, and the cutting assembly can cut the insulation strip to a fixed length when the feeding assembly drives the insulation strip to abut against the positioning block 3;

[0028] Based on the above design, during the production process of the thermal insulation strips, the user uses the feeding assembly to transport the semi-finished thermal insulation strips toward the positioning block 3, and after the thermal insulation strips collide with the positioning block 3, the user controls the operation of the cutting assembly and uses the cutting assembly to cut the thermal insulation strips. The distance between the positioning block 3 and the cutting assembly is the length of the fixed-length cutting of the thermal insulation strips. When the cutting length is required, it is only necessary to adjust the position of the positioning block 3.

[0029] Further, the knife holder assembly includes a transverse plate 7, a cutting knife 8 is fixedly connected to the lower surface of the transverse plate 7, and a press frame 9 is slidably connected to the lower surface of the transverse plate 7, a compression spring 10 is fixedly connected to the upper surface of the press frame 9, and the upper end of the compression spring 10 is arranged against the lower surface of the transverse plate 7, the workbench 1 is provided with a clearance groove on the lower surface of the transverse frame, and a cutting table 11 is rotatably connected to one side of the clearance groove through a spring shaft, and a cross bar 12 is fixedly connected to the side of the workbench 1 close to the clearance groove, and the cross bar 12 is fixedly connected to the lower surface of the transverse frame. A shift rod 13 is slidably connected to the rod 12, and a trapezoidal block 15 is fixedly connected to one end of the shift rod 13 close to the cutting table 11, and the trapezoidal block 15 is arranged against the lower surface of the cutting table 11, wherein the slope of the upper end of the trapezoidal block 15 is larger and the slope of the lower end of the trapezoidal block 15 is smaller, that is, the resistance when the cutting table 11 rotates downward is larger, but the resistance when the cutting table 11 rotates upward and resets is smaller, and a reset spring 14 is fixedly sleeved on the shift rod 13, and the end of the reset spring 14 away from the trapezoidal block 15 is fixedly connected to the cross bar 12;

[0030] In this design, when the electric push rod 6 drives the cross plate 7 to move downward to cut the thermal insulation strip, the pressure frame 9 is first pressed against the cutting table 11, and then the cutting knife 8 cuts the thermal insulation strip. It should be noted that the cutting knife 8 can cut the thermal insulation strip with the edge of the workbench 1 close to the give way groove, and the cutting table 11 does not need to provide a support effect. After the cutting knife 8 has completed cutting the thermal insulation strip, the elastic force of the compression spring 10 can drive the cutting table 11 to overcome the resistance of the trapezoidal block 15, thereby causing the cutting table 11 to rotate to an inclined state. At this time, the cutter on the cutting table 11 is The broken part of the insulation strip slides down along the cutting table 11 to realize the unloading operation of the finished product, and when the electric push rod 6 drives the cross plate 7 to reset upward, the compression spring 10 first relaxes to the expanded state, and the pressing frame 9 still presses the cutting table 11 until the compression spring 10 can drive the pressing frame 9 to move upward, so that the cutting table 11 can be kept in the inclined state for a longer time, thereby ensuring that the insulation strip on the cutting table 11 has sufficient sliding time, and when the cross plate 7 returns to the initial position, the cutting table 11 also rotates to the initial state, and the next insulation strip fixed-length cutting operation can be carried out.

[0031] Further, the feeding assembly includes a trough opened on the upper surface of the workbench 1, a vertical frame 16 is fixedly connected in the trough, and two shafts are rotatably connected to the vertical frame 16, one end of the shaft close to the trough is fixedly connected to a pinch wheel 18, and the end of the shaft away from the pinch wheel 18 is fixedly connected to a mutually meshing gear 17, and a driving motor 19 is also fixedly connected to the vertical frame 16, and the output end of the driving motor 19 is fixedly connected to one of the shafts;

[0032] In this design, a driving motor 19 is used in conjunction with the meshing gears 17, so that the pinching wheels 18 can rotate synchronously and in opposite directions, thereby pinching the thermal insulation strips to achieve the purpose of automatic feeding. It should be noted that when users convey different types of thermal insulation strips, they can replace pinching wheels 18 of different specifications to ensure the pinching effect of the thermal insulation strips. This type of pinching device does not require fixed-length conveying, and only needs to convey the thermal insulation strips to a state where they are against the positioning block 3. On the other hand, the thermal insulation strips slide along the upper surface of the workbench 1, and the feeding assembly only provides power for the thermal insulation strips to move toward the positioning block 3.

[0033] Furthermore, a guide groove 20 is provided on the support frame 5, and a slider 21 is fixedly connected to the cross plate 7. The slider 21 is slidably connected to the guide groove 20, and the guide groove 20 is a polygon. Based on the above design, the guide groove 20 is used in conjunction with the slider 21, so that the tool holder can move toward the positioning block 3 while moving downward, and when resetting upward, it also continues to move upward and then returns to the initial position. This design is to further improve the processing efficiency. When the cutting knife 8 cuts off the thermal insulation strip, the feeding assembly can operate and drive the thermal insulation strip to move toward the positioning block 3, and the cutting knife 8 will not interfere with the thermal insulation strip when it moves up and resets. In this way, when performing continuous operations, the processing gap can be reduced to a certain extent, the production cycle can be shortened, and the production efficiency can be improved.

[0034] Furthermore, a pressure sensor is embedded in the positioning block 3, and the pressure sensor is electrically connected to a controller for controlling the feeding component and the cutting component. By using the pressure sensor in conjunction with the controller, automated cutting operations can be realized, and the present solution already has automatic unloading, loading and positioning functions, and only the operating timing of the cutting component needs to be controlled.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
