[0002] Adhesive-backed foam is a foam material with adhesive backing, usually made of polyurethane, polyethylene or other types of foam plastics. Adhesive-backed foam is widely used in construction, automotive, electronics, home furnishing and industrial fields. It is often used for sealing, sound insulation, shock absorption, fixing and protection. Adhesive-backed foam usually has good elasticity, toughness and durability and can withstand a certain amount of pressure and deformation.

[0003] Slitting of adhesive-backed foam refers to the process of slitting foam materials with adhesive to meet different application requirements. Typically, a slitting machine is used to slit the foam material into strips of different widths as needed to adapt to specific application scenarios.

[0004] For example, a Chinese patent with patent number CN209078800U discloses that different widths of adhesive foam strips can be cut as needed. The hydraulic cylinder drives the knife holder and blade to move downward, and the motor drives the screw to rotate, causing the connecting seat to move back and forth, thereby moving the knife holder and blade back and forth to perform the slitting function.

[0005] While the aforementioned cited patent achieves the slitting of adhesive-backed foam in actual use, it still has certain limitations. Specifically, the pressure plate used in the patent limits the adhesive-backed foam by restricting its movement on both sides. This method of restriction can easily cause the adhesive-backed foam in the middle to bulge and become misaligned, affecting the appearance and function of the final product. Therefore, an adhesive-backed foam slitting device is proposed to address the above problems. Utility Model Content

[0034] Lower pressing seat 43 is inverted L-shaped, and clamping plate 44 is integrally connected to the top of lower pressing seat 43, and the bottom surface of clamping plate 44 abuts against the top wall of striping positioning plate 6.

[0035] In the embodiment, the striping positioning plate 6 is arranged between the striping positioning plate 6 and the back adhesive foam body 5, and the four groups of limiting components 4 are arranged on the mobile base 3 to press and limit the striping positioning plate 6. At this time, the striping positioning plate 6 arranged can cooperate with the mobile base 3 to clamp and limit the back adhesive foam body 5. Compared with the single side limiting mode in the cited document, the striping positioning plate 6 of the present application can cooperate with the limiting component 4 to realize the overall covering and limiting of the back adhesive foam body 5, greatly reducing the movement and deformation of the back adhesive foam body 5 during striping, avoiding the bulging phenomenon of the back adhesive foam body 5 during striping, thereby improving the stability and accuracy of striping. At the same time, by arranging a plurality of striping grooves 61 on the striping positioning plate 6, it can be ensured that the striping cutter body 14 always moves along the predetermined path during striping, reduces the striping error, and ensures that the width of each foam is consistent.

[0036] Further, through the adjustment and use of the limiting assembly 4 and the active placement of the slitting positioning plate 6, the limiting assembly 4 and the slitting positioning plate 6 of the present application can also adjust the limiting height according to the different thicknesses of the back adhesive foam body 5, so that the slitting process is more flexible and can adapt to various production needs.

[0037] Specifically, referring to Figures 1-2 , Figure 4 , a plurality of slitting grooves 61 are formed on the slitting positioning plate 6; one end of each of the plurality of slitting grooves 61 is formed in a penetrating manner; and a triangular protrusion is formed at the bottom of the clamping plate 44.

[0038] In this embodiment, the plurality of slitting grooves 61 provided on the slitting positioning plate 6 can be used for the slitting cutter body 14 to pass through, so as to perform slitting work on the back adhesive foam body 5. The triangular protrusion formed at the bottom of the clamping plate 44 can ensure that when the slitting positioning plate 6 is tightly abutted, the contact area between the clamping plate 44 and the slitting positioning plate 6 is reduced.

[0039] Further, considering that the back adhesive foam body 5 has different slitting size requirements and also has various sizes, the user can pre-manufacture slitting positioning plates 6 of different size specifications, and adjust the spacing and width of the slitting grooves 61 on the slitting positioning plate 6 according to the slitting requirements, so as to adapt to and adjust the back adhesive foam body 5 of different size specifications.

[0040] Specifically, referring to Figure 4 , a bearing member is installed in the vertical plate 41, and a threaded rod 45 is rotatably arranged in the vertical plate 41. The threaded rod 45 is vertically arranged and extends to engage with the pressing seat 43.

[0041] In this embodiment, the threaded rod 45 is rotationally connected with the vertical plate 41 during use, but does not engage with the vertical plate 41. The bearing member provided in the vertical plate 41 can be used to install the threaded rod 45.

[0042] Specifically, referring to Figure 4 , the top end of the threaded rod 45 penetrates the pressing seat 43 and extends to install a rotating handle 46.

[0043] In this embodiment, the rotating handle 46 provided can be used to rotationally control the threaded rod 45.

[0044] Further, when the slitting positioning plate 6 is placed on the back adhesive foam body 5, the user can rotate the rotating handle 46 at this time. When the rotating handle 46 is rotated, the threaded rod 45 connected with the rotating handle 46 can be synchronously rotated. At this time, the sliding connection between the pressing seat 43 and the light rod 42 is achieved, so that the pressing seat 43 provided can drive the clamping plate 44 to move vertically along the stroke range of the pressing seat 43.

[0045] Specifically, referring toFigure 1 The upper end surface of the slitting platform 1 is provided with a gantry 7, the gantry 7 is provided with a second linear lead screw module 8, the second linear lead screw module 8 is perpendicular to the first linear lead screw module 2; the second linear lead screw module 8 is provided with a wall plate 9, and the side surface of the wall plate 9 is provided with a third linear lead screw module 10.

[0046] In this embodiment, the user drives the first linear lead screw module 2 to move the moving base 3 and the limiting assembly 4 as a whole until the back adhesive foam body 5 and the slitting positioning plate 6 mounted on the moving base 3 can move to the lower side of the plurality of slitting cutter bodies 14.

[0047] Further, the user can control the second linear lead screw module 8 to drive the wall plate 9 to move the third linear lead screw module 10 in a linear manner in the horizontal direction; and the user can control the third linear lead screw module 10 to drive the moving table 11 mounted on the third linear lead screw module 10 to move in a linear manner in the vertical direction.

[0048] Specifically, referring to Figure 1 and Figure 3 , the third linear lead screw module 10 is provided with a moving table 11 on the side surface, the side surface of the moving table 11 is provided with a cross beam 12, the cross beam 12 is provided with a plurality of sliding block seats 13, and the bottom of each sliding block seat 13 is provided with a slitting cutter body 14; the top of the sliding block seat 13 is provided with an adjusting screw 15, and the top of the adjusting screw 15 penetrates through the sliding block seat 13 and abuts against the top wall of the cross beam 12.

[0049] In this embodiment, in use, the user controls the second linear lead screw module 8 and the third linear lead screw module 10 to drive the plurality of slitting cutter bodies 14 to pass through the 16 and contact the back adhesive foam body 5, at this time, the user drives the first linear lead screw module 2 to drive the moving base 3 to move in a linear manner, and at this time, the slitting cutter body 14 can be used to perform the slitting operation on the back adhesive foam body 5.

[0050] Further, the first linear lead screw module 2 is used to control the movement of the moving base 3 and the limiting assembly 4, and the second linear lead screw module 8 and the third linear lead screw module 10 are used to control the linear movement, so that the plurality of slitting cutter bodies 14 mounted on the third linear lead screw module 10 can move in multiple directions in a precise manner, so that the slitting position of the slitting cutter body 14 can be adjusted flexibly according to different slitting requirements, so as to adapt to different sizes and shapes of the foam product. Meanwhile, a plurality of slitting cutter bodies 14 are mounted on the cross beam 12, and the adjusting screw 15 is used to adjust the spacing of the slitting cutter bodies 14, so that the slitting device can also perform multiple slitting processes, and the slitting size and the slitting spacing can be adjusted freely.

[0051] Furthermore, considering that the adhesive-backed foam body 5 has different slitting requirements, the user can loosen the adjusting bolt 15 so that the adjusting bolt 15 can be released from the tight contact with the slider seat 13. At this time, the slider seat 13 can drive the slitting cutter body 14 to slide freely outside the crossbeam 12. The user can adjust the spacing between two adjacent slitting cutter bodies 14 according to the actual slitting requirements, so that the slitting device of this application can adjust the slitting of the adhesive-backed foam body 5 with different spacing sizes.

[0052] The present invention relates to a 5-slitting device for adhesive-backed foam body:

[0053] Step 1: In actual use, the user can place the adhesive-backed foam body 5 to be slit on the upper surface of the moving base 3, and then place the slitting positioning plate 6 on the upper surface of the adhesive-backed foam body 5. At this time, the slitting groove 61 opened on the slitting positioning plate 6 can be used for the slitting cutter body 14 to pass through, thereby performing slitting operation on the adhesive-backed foam body 5. At the same time, the user can prefabricate slitting positioning plates 6 of different sizes and adjust the slitting groove 61 on the slitting positioning plate 6 according to the slitting requirements.

[0054] Step 2: After the slitting positioning plate 6 is placed on the adhesive foam body 5, the user can rotate the handle 46. When the handle 46 is rotated, the threaded rod 45 connected to it can rotate synchronously. At this time, due to the sliding connection between the pressure seat 43 and the light rod 42, the pressure seat 43 can drive the clamping plate 44 to move vertically up and down along the stroke range of the pressure seat 43. The user can adjust the direction of the handle 46 by rotating it, and make the pressure seat 43 move down until it contacts the top of the slitting positioning plate 6. At this time, the four clamping plates 44 in the four sets of limiting components 4 can limit the slitting positioning plate 6, thereby preventing the slitting positioning plate 6 from shifting.

[0055] Step 3: The slitting positioning plate 6 can be used to cover and limit the entire adhesive foam body 5, and the slitting groove 61 opened on the slitting positioning plate 6 can be used for the slitting cutter body 14 to pass through. The user drives the first linear screw module 2, which drives the moving base 3 and the limiting component 4 to move as a whole until the adhesive foam body 5 and the slitting positioning plate 6 installed on the moving base 3 can move to below several slitting cutter bodies 14. At this time, the user controls the second linear screw module 8 and the third linear screw module 10, and at the same time, the several slitting cutter bodies 14 installed on the moving table 11 can pass through 16 and contact the adhesive foam body 5. At this time, the user drives the first linear screw module 2 again and makes the moving base 3 move linearly. At this time, the slitting operation of the adhesive foam body 5 can be realized through the slitting cutter body 14.

[0056] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
