Description

Technical Field

[0001] The present application relates to the technical field of automobile sealing strip processing, and in particular to an automobile sealing strip skeleton cutting mechanism. Background Art

[0002] The automotive sealing strip is mainly composed of a dense rubber matrix and a sponge rubber foam tube. The dense rubber matrix contains a metal skeleton, which plays a role in strengthening the shaping and fixing of the sealing strip. In the production of automotive sealing strip skeletons, in order to improve the production efficiency of automotive sealing strip skeletons, generally two integrated skeletons are formed at one time, and they need to be cut into two skeletons for use.

[0003] At present, the general method of roller cutting is to cut the framework of automobile sealing strips. It drives two offset roller cutting bodies through two supporting shafts, and uses the gap between the two offset roller cutting bodies to form a cutting match to cut the framework. It can effectively cut the framework while ensuring the verticality of the cut. However, during cutting, the two cut frameworks are curled under the rotation of the two roller cutting bodies, which makes it difficult to ensure the overall flatness and affects the quality of the product; at the same time, during cutting, the framework moves under the action of the roller cutting body and is prone to offset, which makes it difficult to ensure the consistency of the width of the framework after cutting, which is easy to cause damage to the framework cutting, affecting the yield and efficiency of the automotive sealing strip framework cutting.

[0004] Therefore, the present application provides a car sealing strip skeleton cutting mechanism to solve the above problems. Utility Model Content

[0005] The present application provides a slitting mechanism for a car sealing strip skeleton, aiming to solve the problems raised in the background technology that the existing roller cutting device is prone to curling during slitting, making it difficult to ensure the overall flatness of the skeleton, and that the skeleton is prone to offset during slitting, making it difficult to ensure the consistency of the width of the skeleton after slitting.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a cutting mechanism for an automobile sealing strip skeleton, comprising a support body, two support shafts arranged up and down on the inner side of the support body and rotatably connected to the support body, and a roller cutter fixedly mounted on the support shaft, the roller cutters on the two support shafts are staggered, and the gap between the two roller cutters forms a cutting fit; a support roller is fixedly mounted on the support shaft, the support rollers on the two support shafts are staggered, and one end of the support roller is connected to one end of the roller cutter; wherein the support roller is made of polyurethane material; a guide pressure plate is fixedly mounted on the support shaft, and the guide pressure plates on the two support shafts are staggered for contacting the outer edge of the automobile sealing strip skeleton. In this way, when slitting, the support roller is used to support the side of the skeleton away from the incision to prevent the skeleton from curling under the action of the roller cutter after slitting. While ensuring the overall flatness of the skeleton after slitting, the guide pressure plate contacts the outer edge of the skeleton to guide the movement of the skeleton to prevent the skeleton from shifting when the roller moves, thereby effectively ensuring the consistency of the width of the skeleton after slitting and improving the yield and efficiency of skeleton slitting.

[0007] In order to enable the guide pressure plate to contact the edges of both sides of the skeleton to guide the movement of the skeleton; preferably, the outer diameter of the guide pressure plate is at least larger than the outer diameters of the roller cutter and the support roller.

[0008] In order to adjust the cutting gap between the two roller cutters and ensure the cutting depth of the roller cutters during the slitting process; preferably, the slitting mechanism also includes a slider that moves longitudinally on the support body and an adjustment structure arranged on the support body for driving the slider to move, wherein one of the support shafts is rotatably mounted on the slider.

[0009] In order to ensure the stability of the movement of the slider, preferably, a guide groove is provided on the support body, and the slider is slidably installed inside the guide groove.

[0010] In order to adjust the position of the slider and further adjust the cutting gap between the two roller cutters, preferably, the adjustment structure includes a screw fixedly mounted on the slider and longitudinally passing through one end of the support body, and an adjustment nut rotatably mounted on the support body and threadedly connected to the screw.

[0011] The automobile sealing strip skeleton slitting mechanism is provided with a supporting roller made of polyurethane material. Under the cooperation of the supporting roller and the roller cutter, the skeleton is slit while keeping the slit skeleton moving horizontally, so as to avoid the slit skeleton from curling under the rotation of the roller cutter, thereby ensuring the overall flatness of the slit skeleton.

[0012] The automobile sealing strip skeleton slitting mechanism can limit the skeleton from the width direction by setting a guide pressure plate, so as to avoid the skeleton from shifting during slitting, so that the roller cut is always on a horizontal line, ensuring the consistency of the width of the two skeletons after slitting, thereby ensuring the skeleton slitting yield and slitting efficiency.

[0017] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0018] Example 1

[0019] This embodiment provides a car sealing strip skeleton cutting mechanism, such as Figure 1 and Figure 2 As shown, the slitting mechanism includes a support body 1, two support shafts 2 arranged up and down on the inner side of the support body 1 and rotatably connected to the support body 1, and a roller cutter 3 fixedly mounted on the support shaft 2. The roller cutters 3 on the two support shafts 2 are staggered, and the gap between the two roller cutters 3 forms a cutting fit.

[0020] In order to ensure the overall flatness of the two skeletons after cutting and improve the quality of the finished products, a support roller 4 is fixedly mounted on the support shaft 2, and the support rollers 4 on the two support shafts 2 are staggered, and one end of the support roller 4 is connected to one end of the roller cutter 3.

[0021] During slitting, when one end of the skeleton to be slit enters the cutting gap between the two roller cutters 3, the skeleton is slit while the friction between the two roller cutters 3 and the skeleton drives the skeleton to continuously move into the cutting gap between the two roller cutters 3 to achieve the slitting of the skeleton; the slit skeleton is supported by the support roller 4, and with the cooperation of the support roller 4 and the roller cutter 3, the slit skeleton maintains horizontal movement to avoid curling of the slit skeleton under the rotation of the roller cutter 3, thereby ensuring the overall flatness of the slit skeleton.

[0022] It should be noted that in order to support the skeleton and prevent the support roller 4 from interfering with the roller cutter 3 in slitting the skeleton, the support roller 4 is made of polyurethane material. It is understandable that the support roller 4 made of polyurethane material has a certain rigid support force and elasticity, which can effectively support the side of the skeleton away from the roller cutter 3 and prevent the support roller 4 from interfering with the two roller cutters 3 when slitting the skeleton, thereby ensuring that the roller cutter 3 can achieve slitting of the skeleton.

[0023] In order to achieve the mobile guiding of the skeleton, ensure the consistency of the width of the two skeletons after slitting, and ensure the yield of skeleton slitting; a guide pressure plate 5 is fixedly mounted on the support shaft 2, and the guide pressure plates 5 on the two support shafts 2 are staggered and used to contact the outer edge of the automobile sealing strip skeleton.

[0024] During slitting, when one end of the skeleton to be slit enters the cutting gap between the two roller cutters 3, the two guide pressure plates 5 contact the two sides of the skeleton respectively, and the width of the skeleton is limited by the two guide pressure plates 5, so that the skeleton moves along the two guide pressure plates 5, thereby avoiding the skeleton from shifting during slitting, and making the roller cut always on a horizontal line, thereby ensuring that the widths of the two skeletons after slitting are consistent.

[0025] It should be noted that, in order to limit the width of the skeleton, the skeleton is guided to move; the outer diameter of the guide platen 5 is at least larger than the outer diameters of the roller cutter 3 and the support roller 4. In this way, after one end of the skeleton to be cut enters the cutting gap between the two roller cutters 3, the two side edges of the skeleton can contact the guide platen 5, so that the guide platen 5 can limit the skeleton in the width direction.

[0026] Example 2

[0027] In order to adjust the cutting gap between the two roller cutters 3 and ensure the cutting depth of the roller cutters 3 during the slitting process; different from Example 1, as Figure 1As shown, the slitting mechanism further includes a slider 6 that moves longitudinally on the support body 1 and an adjustment structure 7 that is arranged on the support body 1 and is used to drive the slider 6 to move, wherein one of the support shafts 2 is rotatably mounted on the slider 6. A guide groove 11 is provided on the support body 1, and the slider 6 is slidably mounted inside the guide groove 11.

[0028] When in use, the slider 6 can be driven to move by adjusting the structure 7 according to the thickness of the skeleton, so that the slider 6 drives one of the support shafts 2 to move closer to or away from the other support shaft 2 on the support body 1, thereby adjusting the cutting gap between the roller cutters 3 on the two support shafts 2 to ensure the cutting depth of the roller cutter 3 during the slitting process.

[0029] Specifically, the adjustment structure 7 includes a screw rod 71 fixedly mounted on the slider 6 and longitudinally penetrating one end of the support body 1, and an adjustment nut 72 rotatably mounted on the support body 1 and threadedly connected to the screw rod 71. When adjusting the cutting gap, the adjustment nut 72 is rotated to make the screw rod 71 move up and down on the nut 72, so that the screw rod 71 drives the slider 6 to move on the support body 1, and drives the support shaft 2 on the slider 6 to move closer to or away from another support shaft 2, so as to adjust the cutting gap.

[0030] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes according to the technical solution and concept of the present application within the technical scope disclosed in the present application, which should be covered by the protection scope of the present application.
