Description

Technical Field

[0001] This utility model belongs to the field of dipped canvas cutting technology, specifically relating to a dipping machine cutting device for dipped canvas production. Background Technology

[0002] Rubber-impregnated canvas is a material made by impregnating fibrous materials with a rubber solution. The impregnation process includes steps such as heat stretching and heat setting, aiming to improve the adhesion between the canvas and rubber while meeting the various technical performance requirements of the finished canvas. Rubber-impregnated canvas features strong water resistance, abrasion resistance, weather resistance, high gloss, and environmental safety. During production, rubber-impregnated canvas is typically cut using a rubber-impregnation machine cutting device. This device not only allows for fast and accurate cutting, improving production efficiency, but also ensures cutting precision and dimensional stability, meeting customers' customization needs.

[0003] Chinese Patent Publication No. CN216972948U belongs to the field of dipped canvas cutting. It includes a vertical plate with two meshing gears. Each gear has a rotating roller coaxially mounted on it, the diameter of which is smaller than the gear. Each rotating roller is equipped with a cutter. A linear moving component is provided on the vertical plate, connected to a rack. The rack meshes with one of the gears. Suction pipes are located on the side of the cutter facing the feeding direction, and these pipes are connected to the vertical plate via linear elastic components. The vertical plate is fixed in position by brackets, etc. In the initial state, the blades of both cutters are in contact with the surface of the dipped canvas. When the dipped canvas is conveyed, it undergoes relative displacement with the cutters, thereby removing burrs, glue nodules, etc., from the surface of the dipped canvas without producing smoke, odor, or leaving any residue.

[0004] In practical use, this utility model typically involves using cutting shears to accurately cut the glued canvas. However, when the cutting shears of existing glued canvas cutting devices are in continuous contact with and cutting, a layer of small residue from the glued canvas often adheres to their surface. This residue accumulates on the cutting shear blades, increasing the load on the shears, reducing their cutting efficiency, and directly and negatively impacting the cutting accuracy and overall effect of the glued canvas. As the residue accumulates on the cutting shears, the sharpness of the blade gradually decreases, resulting in uneven cut edges or even deviations, severely affecting the finished quality and appearance of the glued canvas.

[0032] Two fixing plates 9 are respectively set on both sides of the base plate 1, and two guide rollers 10 are provided between the two fixing plates 9.

[0033] Specifically, such as Figure 1 and Figure 2 As shown, a cylinder 11 is provided at the upper end of the mounting frame 3. The cylinder 11 is existing technology and will not be described in detail here. The output end of the cylinder 11 passes through the upper end of the mounting frame 3 and is set at the upper end of the positioning plate 4. The output end of the cylinder 11 can drive the positioning plate 4 and the cutting shears 5 to move up and down, thereby completing the cutting operation of the dipped canvas. Guide plates 12 are provided on both sides of the positioning plate 4. Guide grooves that are adapted to the guide plates 12 are provided on both sides of the mounting frame 3. The two guide plates 12 are located in the two guide grooves respectively and are slidably connected to the side walls of the guide grooves. The guide plates 12 at both ends of the positioning plate 4, together with the guide grooves on both sides of the mounting frame 3, can limit the position of the positioning plate 4 and the cutting shears 5, preventing them from shifting their position during movement, thereby ensuring the accuracy of cutting the dipped canvas.

[0034] Specifically, such as Figure 1 As shown, a support platform 13 is provided on the upper end of the base plate 1 located at the bottom of the cutting scissors 5. The upper end of the support platform 13 has a cutting opening that is compatible with the cutting scissors 5. The support platform 13 and the upper cutting opening can support the dipped canvas and enable the cutting scissors 5 to cut the dipped canvas better.

The bottom end of the mounting rod 17 is provided with a limiting spring 18, and the bottom end of the limiting spring 18 is set on the inner wall of the mounting sleeve 7. By cooperating with the mounting rod 17 and the limiting spring 18, the cleaning frame 8 can always be pressed against the bottom end of the cutting scissors 5, so that the cleaning frame 8 can clean the glued canvas residue on the surface of the cutting scissors 5 when the cutting scissors 5 is at different heights.

[0039] See Figure 1-4 In the production process of dipped canvas, a dipping machine cutting device is usually used to cut the dipped canvas. During the cutting process, the dipped canvas needs to be passed through the mounting frame 3 and placed on the support platform 13. When the dipped canvas needs to be cut, the cylinder 11 needs to be activated. The output end of the cylinder 11 will drive the positioning plate 4 to move downward. The positioning plate 4 will drive the cutting blades 5 to move downward to cut the dipped canvas. After the dipped canvas is cut, the cylinder 11 will drive the positioning plate 4 and the cutting blades 5 to move upward. When the positioning plate 4 moves, it will drive the adjusting shaft 14 and the adjusting block 6 to move to one side through the adjusting port 15. The adjusting block 6 will drive the cleaning frame 8 to move, so as to conveniently clean the dipped canvas residue adhering to the surface of the cutting blades 5, ensuring the efficiency and accuracy of the dipping machine cutting device in cutting the dipped canvas.
