Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of polymer profile processing equipment, and specifically relates to a high-efficiency cutting mechanism for floor foaming sound-absorbing film. Background Technology
[0002] Floor foam sound insulation film is a bottom layer sound insulation and moisture-proofing material used in floor installation. It is widely used in various flooring types, including solid wood flooring, bamboo flooring, and composite flooring. It can reduce foot traffic noise, isolate noise from floors above and below, and extend the lifespan of the flooring. Common floor foam sound insulation film materials include IXPE (electronically cross-linked polyethylene foam) and IXPP (irradiated cross-linked polypropylene foam).
[0003] Many high-end commercially available flooring and tile products come with a pre-formed sound-absorbing foam film attached to the bottom surface. This requires the size of the sound-absorbing foam film to match the dimensions of the flooring or tiles. Therefore, on the production line for sound-absorbing foam film, after continuous extrusion of long, flat preforms through blending, cross-linking treatment with irradiation equipment and foaming with foaming equipment, the film needs to be cut along its width to obtain dimensions suitable for commercially available decorative flooring.
[0004] To reduce uneven cuts caused by movement of the foamed sound-absorbing flooring film during cutting, the applicant's previous cutting mechanisms integrated the cutter and pressure roller together. During cutting, the pressure roller kept the foamed sound-absorbing flooring film flattened downwards (as in the applicant's previous patent application, "A Cutting Device for Foamed Floor Mat Production," 202321772901.3). However, in this structure, the pressure roller 64 is always flush with the cutting direction of the cutter 7, and in its natural state, the bottom of the cutter 7 is flush with the bottom of the pressure roller 64 (segment 0042, lines 7 and 8 from the bottom in 202321772901.3). This requires the cutter 7 to first vertically pierce the foamed sound-absorbing flooring film 2 to ensure that the pressure roller 64 elastically presses down on the film before driving the cutter 7 to move laterally to achieve the cut (segment 0042 in 202321772901.3). In this case, after one cut (see attached...). Figure 1 The middle arrow indicates the direction of the cut in one cut, and the long dashed line indicates the entire distance traveled by the cutter 7 during one cut. The area on the floor foam soundproof membrane 2 located in the opposite direction of the cutter 7's first cut (see attached image). Figure 1 The circled part (indicated by "A") is not cut off. The cutter 7 needs to move back and forth along the path of the first cut to achieve a complete cut. This is not only time-consuming, but also prone to causing secondary cuts to the cut surface, resulting in a decrease in the flatness of the cut.
[0005] In this cutting mechanism, if the cutter 7 is lowered to the cutting height directly on the outside of the floor foam soundproofing film 2 before horizontal cutting, when the cutter 7 and the pressure roller 64 reach the side edge of the floor foam soundproofing film 2, it will cause the floor foam soundproofing film 2 to warp or shift (as shown in the attached diagram). Figure 2 , 3 (where the arrow indicates the cutting direction), which also affects the dimensional accuracy and cut smoothness of the floor foam soundproof membrane 2 after cutting. Utility Model Content
[0006] To solve the above technical problems, this utility model provides a high-efficiency cutting mechanism for floor foam sound insulation film, including a cutting platform with a horizontal length direction, and the floor foam sound insulation film to be cut is laid horizontally on the cutting platform and transported from left to right.
[0007] On the cutting platform, mounting blocks extend vertically upwards symmetrically at the front and rear. A first drive motor is fixedly mounted on the front mounting block. A first lead screw extending horizontally backwards from the first drive motor axially rotates and engages with the front mounting block before embedding into the rear mounting block. A first guide rod, parallel to the first lead screw, is fixedly mounted on either the horizontal left or right side of the first lead screw. The two ends of the first guide rod along its length are correspondingly fixed to the mounting blocks on the front and rear sides. A slider, threaded onto the first lead screw, is simultaneously fitted onto the first guide rod. The slider is vertically fixed downwards to a push rod that runs horizontally in the left-right direction along its length. The push rod is vertically downward and parallel to the horizontal surface of the cutting platform; a limiting rib is fixed on the cutting platform behind the push rod, which is corresponding to the push rod in the front and back direction. The limiting rib is formed by a vertically upward protrusion of a part of the cutting platform surface, and the limiting rib is horizontally set in the left and right directions in the length direction; the first drive motor drives the first lead screw to rotate axially, thereby driving the slider to slide back and forth along the length direction of the first lead screw and the first guide rod at the same time, and synchronously driving the push rod to move, so as to realize the push rod approaching or moving away from the limiting rib, and the floor foam sound insulation film is precisely between the push rod and the limiting rib for the transmission;
[0008] Meanwhile, a first receiving groove is formed by a local horizontal forward indentation on the vertical inner side of the push rod, connecting the upper and lower horizontal surfaces of the push rod. A second receiving groove is formed by a horizontal backward indentation on the vertical inner side of the limiting rib, corresponding to the first receiving groove, connecting the upper and lower horizontal surfaces of the limiting rib. In addition, the vertical downward distance between the horizontal top surface of the push rod and the horizontal top surface of the limiting rib and the cutting platform surface is greater than the thickness of the floor foam sound insulation film. Furthermore, the inner edge of the top surface of the push rod and the inner edge of the top surface of the limiting rib are both arc edges, and the arc extends downward to a horizontal upper surface lower than the floor foam sound insulation film.
[0009] The cutting platform is symmetrically equipped with mounting brackets at the front and rear. A second drive motor is fixedly mounted on the top of the rear mounting bracket. The second lead screw of the second drive motor extends horizontally forward and can be axially rotated to pass through the rear mounting bracket and then engage with the front mounting bracket. A second guide rod parallel to the second lead screw is fixedly mounted on the horizontal left or right side of the second lead screw. The two ends of the second guide rod along its length are fixed to the mounting brackets on the front and rear sides respectively. A slide block threaded onto the second lead screw is also threaded onto the second guide rod. The second drive motor drives the second lead screw to rotate axially, thereby threading the slide block to reciprocate along the length of both the second guide rod and the second lead screw.
[0010] A cylinder is fixedly installed at the bottom of the slide block. A horizontal mounting plate with a longitudinal direction (front-to-back) is fixed to the bottom end of a telescopic rod extending vertically downwards from the cylinder. The telescopic rod is fixed at the center of the mounting plate's length. Simultaneously, a cutter extends vertically downwards from the center of the mounting plate's length. The cutter's blade is a vertical plane extending forward-to-back, and it is a double-edged blade with two opposing cutting edges, one horizontally forward and the other horizontally backward. Pressure roller mechanisms extend vertically downwards from the front and rear sides of the cutter on the mounting plate. The distance between the two pressure roller mechanisms and the cutter is equal along the length of the mounting plate. Each pressure roller mechanism includes a vertically oriented mounting cylinder extending downwards from the mounting plate. The cylinder opening is vertically downwards. A vertically oriented movable column is inserted into the mounting cylinder through the cylinder opening. The movable column and the mounting... The top and bottom of the cylindrical cavity are elastically fixedly connected by a vertically axial spring. The mounting cylinder is also equipped with a limiting mechanism, which includes a groove on the mounting cylinder body that is parallel to the axial direction of the mounting cylinder and connects the mounting cylinder cavity to the outside. The groove extends upward along its own length to the bottom of the top of the mounting cylinder cavity. A limiting block extending horizontally outward along its own radial direction on the movable column is fitted into the groove. The groove restricts the horizontal position of the limiting block to prevent the movable column from rotating axially in the mounting cylinder. At the same time, the limiting block can slide back and forth in the groove along its length to cooperate with the axial lifting and lowering of the movable column in the mounting cylinder. A horizontally axial pressure roller is installed at the bottom of the movable column, and the pressure roller can rotate axially at the bottom of the movable column.
[0011] A horizontal through-slot is provided on the cutting platform, with both ends of the through-slot being sealed. The through-slot connects the upper and lower horizontal surfaces of the cutting platform. A floor foam sound-absorbing membrane covers the through-slot, with openings at both ends. The two openings face upward and connect to the first and second receiving slots respectively. Driven by a cylinder, the cutter vertically downward passes through the first receiving slot and extends into the front opening. At this time, the rear edge of the cutter is facing the front edge of the floor foam sound-absorbing membrane. At the same time, the pressure roller on the rear side elastically presses the floor foam sound-absorbing membrane downward onto the cutting platform surface, while the pressure roller on the front side elastically abuts against the top of the push rod.

Detailed Implementation
[0021] It should be noted that the terms "front," "back," "left," "right," "horizontal," and "vertical" used in the description of this application refer to the appendix. Figure 4 , 5 In 6, 7, and 8, "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.
[0022] As attached Figure 4As shown, the high-efficiency cutting mechanism for the floor foam sound-absorbing film of this utility model first includes a cutting platform 1 that is horizontal in the left-right direction. The floor foam sound-absorbing film 2 to be cut is laid horizontally on the cutting platform 1 and is transported from left to right along its own length direction. Mounting blocks 12 extend vertically upwards symmetrically in the front and rear directions along the width direction of the cutting platform 1. A first drive motor 8 is fixedly mounted on the front mounting block 12. A first lead screw 81 extending horizontally backwards from the first drive motor 8 is axially rotatable, passing through the front mounting block 12 and then engaging with the rear mounting block 12. A first guide rod 82, parallel to the first lead screw 81, is fixedly mounted on the horizontal right side of the first lead screw 81. The two ends of the first guide rod 82 are correspondingly fixed to the front and rear mounting blocks 12. A slider (not shown in the attached figure due to the viewing angle) threaded onto the first lead screw 81 is simultaneously engaged with the first guide rod 82. The slider is vertically fixed to a push rod 84 that is horizontal in the left-right direction along its length. The push rod 84 is vertically downward and parallel to the horizontal surface of the cutting platform 1. A limiting rib 13, which is corresponding to the push rod 84 and is located behind the push rod 84, is also fixed on the cutting platform 1. The limiting rib 13 is formed by a local vertical upward protrusion on the horizontal surface of the cutting platform 1 and is horizontal in the left-right direction along its length. The first drive motor 8 drives the first lead screw 81 to rotate axially, thereby threading the slider to slide back and forth horizontally along the length directions of the first lead screw 81 and the first guide rod 82. Simultaneously, the push rod 84 is pushed back and forth horizontally along the width direction of the cutting platform 1, so as to realize the push rod 84 approaching or moving away from the limiting rib 13. When the push rod 84 is horizontally and parallel to the limiting rib 13 to the appropriate position, the floor foam sound insulation film 2 is precisely between the push rod 84 and the limiting rib 13 for the above-mentioned transmission.
[0023] Meanwhile, a first receiving groove 841 is formed by a local horizontal forward indentation on the vertical inner side of the push rod 84, which connects the upper and lower horizontal surfaces of the push rod 84. A second receiving groove 131 is formed by a horizontal backward indentation on the vertical inner side of the limiting rib 13, which corresponds to the first receiving groove 841 in the front and rear upward positions, which connects the upper and lower horizontal surfaces of the limiting rib 13. In addition, the vertical downward distance between the horizontal top surface of the push rod 84 and the horizontal top surface of the limiting rib 13 and the cutting platform 1 is greater than the thickness of the floor foam sound insulation film. Furthermore, the inner edge of the top surface of the push rod 84 and the inner edge of the top surface of the limiting rib 13 are both arc edges, and the arc extends downward to a level lower than the horizontal upper surface of the floor foam sound insulation film 2.
[0024] Not far to the right of the mounting block 12, a horizontal through groove 11 with a length direction of front and back is provided on the cutting platform 1. Both ends of the through groove 11 are sealed. The through groove 11 connects the upper and lower horizontal surfaces of the cutting platform 1. The floor foam sound insulation film 2 covers the through groove 11 and leaves openings 111 at both ends of the through groove 11. The two openings 111 face upward and connect to the first receiving groove 841 and the second receiving groove 131 respectively.
[0025] At the location of the through slot 11, mounting brackets 3 are symmetrically fixed on the front and rear sides of the cutting platform 1. A second drive motor 4 is fixedly installed on the top of the front mounting bracket 3. The second lead screw 41 of the second drive motor 4 extends horizontally forward and can be axially rotated to pass through the rear mounting bracket 3 and then be embedded in the front mounting bracket 3. A second guide rod 42 parallel to the second lead screw 41 is fixedly installed on the horizontal right side of the second lead screw 41. The two ends of the second guide rod 42 in the length direction are fixed to the mounting brackets 3 on the front and rear sides respectively. A slide block 43 threadedly fitted on the second lead screw 41 is also fitted on the second guide rod 42. The second drive motor 4 drives the second lead screw 41 to rotate axially, thereby threading the slide block 43 to slide back and forth along the length direction of the second guide rod 42 and the second lead screw 41.
[0026] As attached Figure 5A cylinder 5 is fixedly installed at the bottom of the slide block 43. A horizontal mounting plate 6, with its length direction running forward and backward, is fixedly connected to the bottom end of a telescopic rod extending vertically downward from the cylinder 5. The telescopic rod is fixed at the center of the mounting plate 6's length direction. Simultaneously, a cutter 7 extends vertically downward from the center of the mounting plate 6's length direction. The cutter 7 is a double-edged blade with two opposing cutting edges, one horizontally forward and the other horizontally backward. Pressure roller mechanisms extend vertically downward from the mounting plate 6 on both sides of the cutter 7. The distances between the two pressure roller mechanisms and the cutter 7 along the length direction of the mounting plate 6 are equal, and the two pressure roller mechanisms are of identical specifications. Each pressure roller mechanism includes a vertically extending mounting cylinder 61 on the mounting plate 6, with its axial direction vertical. The opening of the mounting cylinder 61 is vertically downward. A vertically aligned movable column 62 is coaxially inserted into the mounting cylinder 61 through the opening, and the movable column 62 and the horizontal cavity bottom of the mounting cylinder 61 are elastically fixed by a vertically aligned spring 63. The spring 63, mounting cylinder 61, and movable column 62 are all coaxially arranged. The mounting cylinder 61 is also equipped with a limiting mechanism, which includes a groove 611 on the cylinder body of the mounting cylinder 61, whose length direction is parallel to the axial direction of the mounting cylinder 61, and which can horizontally connect the cavity of the mounting cylinder 61 to the outside. The groove 611 extends vertically upward along its own length direction to the bottom of the cavity at the top of the mounting cylinder 61. A limiting block 621 extending horizontally outward along its own radial direction on the movable column 62 is fitted into the groove. In section 611, the position of the limiting block 621 in the horizontal direction is restricted by the slide groove 611 to prevent the movable column 62 from rotating axially in the mounting cylinder 61; at the same time, the limiting block 621 can slide back and forth in the slide groove 611 along the length of the slide groove 611 to cooperate with the axial vertical lifting and sliding of the movable column 62 in the mounting cylinder 61; a pressure roller 64 with a horizontal axis in the left and right direction is installed at the bottom end of the movable column 62, and the pressure roller 64 can rotate axially at the bottom end of the movable column 62.
[0027] The floor foam soundproofing film 2 is transmitted between the push rod 84 and the limiting rib 13 and parallel to the limiting rib 13 (wherein, the position of the push rod 84 is controlled by the first drive motor 8 to adapt to floor foam soundproofing films 2 of different widths; and the through groove 11 also extends to the direction of the push rod 84 with sufficient length, so that when transmitting floor foam soundproofing films 2 of different widths, an opening 111 is left on the front side of the floor foam soundproofing film 2), thus ensuring that the length direction of the floor foam soundproofing film 2 is always perpendicular to the cutting direction of the cutter 7.
[0028] During the subsequent cutting operation, the rightward transmission of the floor foam sound-absorbing membrane 2 on the cutting platform 1 is first paused. Driven by the cylinder 5, the cutter 7 is vertically lowered, passing through the first receiving groove 841 and extending into the front opening 111. This continues until the pressure roller 64 behind the cutter 7 elastically presses the floor foam sound-absorbing membrane 2 vertically downwards onto the horizontal surface of the cutting platform 1 (ensuring that the floor foam sound-absorbing membrane 2 does not lift or slip relative to the cutting platform 1 during subsequent cutting). At this point, the rear blade of the cutter 7 is horizontally aligned with the front edge of the floor foam sound-absorbing membrane 2, while the front pressure roller 64 elastically abuts against the top of the push rod 84. (See attached...) Figure 6 ;
[0029] At this time, the second drive motor 4 is started to drive the slide block 43 to slide horizontally backward along the length direction of the second guide rod 42 and the second lead screw 41, and simultaneously drive the cutter 7 fixed below the slide block 43 to cut the floor foam sound insulation film 2 horizontally backward along its width direction. Meanwhile, the pressure roller 64 on the back side of the cutter 7 keeps the floor foam sound insulation film 2 in a downward elastic pressure on the upper surface of the floor foam sound insulation film 2 and rolls backward.
[0030] Shortly after, the pressure roller 64, located in front of the cutter 7, moves horizontally backward along the slide block 43, rolling down the arc-shaped edge of the push rod 84 and leaving the push rod 84. It then lands on the surface of the newly cut floor foam sound-absorbing membrane 2, applying a vertically downward elastic pressure to the membrane and maintaining this state as it rolls backward, as shown in the attached diagram. Figure 7 ;
[0031] As the pressure roller 64 on the rear side of the cutter 7 rolls backward and leaves the floor foam soundproof film 2, and rolls up the arc edge of the limiting rib 13, the pressure roller 64 on the front side of the cutter 7 continues to elastically press the floor foam soundproof film 2 onto the cutting platform 1 and remain stationary until the cutter 7 completely cuts the floor foam soundproof film 2 along its width (i.e., one cutting operation is completed). At this time, the cutter 7 enters the rear opening 111 and the second receiving groove 131 completely horizontally, while the pressure roller 64 on the front side of the cutter 7 has not yet rolled away from the upper surface of the floor foam soundproof film 2, as shown in the attached figure. Figure 8 At this point, the cylinder 5 drives the pressure roller 64 to rise vertically and detach from the floor foam soundproof film 2;
[0032] At this point, the floor foam soundproofing membrane 2 restarts and continues to be transported to the right for a corresponding distance on the cutting platform 1 before pausing. Driven by the cylinder 5, the mounting plate 6 descends vertically again until the pressure roller 64 located in front of the cutter 7 presses the floor foam soundproofing membrane 2 vertically downwards against the horizontal surface of the cutting platform 1 (the pressure roller 64 located behind the cutter 7 then elastically abuts against the top of the limiting rib 13). Then, following the above pattern, the cutter 7 cuts horizontally forward. This process is repeated.
[0033] In summary, this solution, by providing elastic pressure roller mechanisms on the front and rear sides of the cutter 7, ensures that the floor foam sound-absorbing membrane 2 is pressed firmly before each cut and remains pressed after each cut. This ensures that the floor foam sound-absorbing membrane 2 is elastically pressed onto the cutting platform 1 and remains stationary throughout the entire cutting process (the pressure roller mechanism applies a vertical downward positive pressure to the floor foam sound-absorbing membrane 2, ensuring that the static friction between the floor foam sound-absorbing membrane 2 and the cutting platform 1 is always effectively greater than the rolling friction of the pressure roller mechanism on the floor foam sound-absorbing membrane 2). This prevents the floor foam sound-absorbing membrane 2 from warping or shifting during the cutting process, ensuring that the cut panels are regular in shape, have flat cuts, and are dimensionally accurate.
[0034] Meanwhile, the cutter 7, which adopts a double-edged blade structure, can complete another cutting operation as the cutter 7 returns along the same path after one cutting operation is completed. There is no unnecessary reset of the cutter 7, which has the characteristics of high efficiency and energy saving.
[0035] The inner edge of the top surface of the push rod 84 and the inner edge of the top surface of the limiting rib 13 are both arc edges, and the arc extends downward to the horizontal upper surface below the floor foam sound insulation film 2. This allows the pressure roller 64 to smoothly transition to the arc surface after rolling away from the upper surface of the floor foam sound insulation film 2, and smoothly roll up the arc surface through the elastic contraction of the spring 63, so that the slide 43 and the cutter 7 will not be substantially obstructed during the movement.

The first drive motor (8) drives the first lead screw (81) to rotate axially, thereby thread-driven the slider to slide back and forth along the length of the first lead screw (81) and the first guide rod (82) at the same time, and simultaneously drives the push rod (84) to move along the width of the cutting platform (1), so as to realize that the push rod (84) moves parallel to or away from the limiting rib (13).
7. The high efficiency cutting mechanism of the floor foamed soundproofing film according to claim 6, characterized in that: The cutting platform (1) has mounting blocks (12) fixedly installed on both sides of its width direction respectively. The first drive motor (8) is fixedly installed on one of the mounting blocks (12). The first lead screw (81) can be axially rotated and passes through the mounting block (12) and then is embedded in the other mounting block (12). The two ends of the first guide rod (82) in the length direction are fixedly connected to the two mounting blocks (12) respectively.
8. The high-efficiency cutting mechanism for the floor foam sound-absorbing membrane as described in claim 1, characterized in that: An installation cylinder (61) extends downward from the mounting plate (6). The opening of the installation cylinder (61) faces downward. The movable column (62) is coaxially inserted into the installation cylinder (61) through the opening. The movable column (62) and the bottom of the top cavity of the installation cylinder (61) are elastically fixedly connected by a spring (63). The spring (63), the installation cylinder (61), and the movable column (62) are all coaxially arranged. The bottom end of the movable column (62) is equipped with an axially rotatable pressure roller (64).
9. The high efficient cutting mechanism of the floor foamed soundproofing film according to claim 8, characterized in that: The mounting cylinder (61) is provided with a limiting mechanism, which includes a groove (611) on the body of the mounting cylinder (61) whose length direction is parallel to the axial direction of the mounting cylinder (61) and connects the cavity of the mounting cylinder (61) to the outside. A limiting block (621) extending outward along its own radial direction on the movable column (62) is fitted into the groove (611). The position of the limiting block (621) is restricted by the groove (611) to prevent the movable column (62) from rotating axially in the mounting cylinder (61). At the same time, the limiting block (621) can slide back and forth in the groove (611) along the length direction of the groove (611) to cooperate with the axial lifting and sliding of the movable column (62) in the mounting cylinder (61).
10. The high efficient cutting mechanism of the floor foamed soundproofing film according to claim 9, characterized in that: The groove (611) extends upward along its own length to the bottom of the cavity at the top of the mounting cylinder (61).
