The rack 1 has a working space inside, which is an internal hollow area enclosed by the rack 1, and the size is suitable for the cutting operation demand, which is located between the feeding platform 2 and the discharging platform 3 inside the rack 1.

[0033] The feeding platform 2 is generally a flat structure, which is fixed to the rack 1 by bolts and other fixing parts, and is located at the front side of the working space, which is used to transport the rubber raw materials to be cut to the working space, and provides support and guidance for the raw materials entering the cutting area.

[0034] The discharging platform 3 can be a conveyor belt driven by a motor, which is fixed to the rack 1 by bolts and other fixing parts, and is located at the rear side of the working space, which is opposite to the feeding platform 2, and is used to receive the cut rubber strips and transport them out of the working space for subsequent collection or processing.

[0035] The slitting mechanism 4 is used to realize the slitting work of the rubber raw materials, which mainly includes a knife seat 40, a driving unit 41, an installation chamber 42, an installation rod 43, an installation seat 44, a cutter 45 and the like. The knife seat 40 is generally a block or plate structure, which is located between the feeding platform 2 and the discharging platform 3 in the working space, above the raw materials to be cut, and is connected with the output end of the driving unit 41, which can be vertically reciprocated under the driving of the driving unit 41, which is used to install and carry the cutter 45 and related components, and moves under the driving of the driving unit 41, which provides cutting power for the cutter 45. The installation chamber 42 is a cavity structure opened on the left and right sides of the knife seat 40, which is adapted in size to the installation rod 43, and is located on the left and right sides of the knife seat 40, respectively, extending along the front and rear directions of the knife seat 40, providing installation space and positioning for the installation rod 43, and ensuring the stable fixation of the installation rod 43. The installation rod 43 is a long strip-shaped rod body, and the cross section is generally circular or square, which is installed in the installation chamber 42 along the front and rear directions, and the two ends thereof are connected with the end of the installation chamber 42 through flanges and bolts.

[0036] The spacing adjustment mechanism 5 is used to adjust the position of the installation seat 44 on the installation rod 43 and lock it, so as to change the distance between adjacent cutters 45 to adapt to the demand of rubber strips with different widths.

[0037] In the above design, the rubber raw material to be cut is conveyed to the cutting position in the working space through the feeding platform 2; the driving unit 41 drives the knife holder 40 to move vertically and reciprocally, the cutter 45 on the knife holder 40 moves synchronously with the knife holder 40, and the rubber raw material is cut into strips through the vertical cutting action of the cutter 45; the cut strip-shaped rubber is conveyed out of the working space through the discharging platform 3. When the width of the strip-shaped rubber needs to be changed, the locking of the mounting seat 44 is released by the spacing adjusting mechanism 5, the mounting seat 44 is slid along the mounting rod 43 to the desired position, and then the mounting seat 44 is locked by the spacing adjusting mechanism 5, so that the spacing of the adjacent cutters 45 is changed, thereby realizing cutting of different width specifications.

[0038] The driving unit 41 is a cylinder 410 mounted on the top wall of the working space, and the piston rod of the cylinder 410 is connected with the upper surface of the knife holder 40. The purpose of the above design is to use the cylinder 410 generally in columnar structure as the driving unit 41, which is bolted on the top wall of the working space, and the piston rod of the cylinder 410 is bolted with the upper surface of the knife holder 40. The piston rod of the cylinder 410 is used to drive the knife holder 40 to move vertically and reciprocally, and then drive the cutter 45 to complete the cutting action on the rubber raw material, so as to provide stable power output and ensure the continuity and reliability of the cutting process.

[0039] The mounting seat 44 includes a seat body 440 provided with a sleeve hole 441 matched with the mounting rod 43, and a lower connecting plate 442 provided at the bottom of the seat body 440 and bolted with the cutter 45. The purpose of the above design is to set the seat body 440 in block structure and provided with a sleeve hole 441 matched with the mounting rod 43, and the lower connecting plate 442 in plate structure, which is provided at the bottom of the seat body 440 and fixedly connected with the seat body 440, such as welding or integral molding, so that the seat body 440 can be slidably matched with the mounting rod 43 through the sleeve hole 441, realizing flexible movement of the mounting seat 44 along the mounting rod 43; at the same time, the cutter 45 is stably fixed on the mounting seat 44 by bolt connection of the lower connecting plate 442 with the cutter 45, which not only ensures the position stability of the cutter 45 during cutting, but also facilitates the disassembly and replacement of the cutter 45, thereby balancing the stability of the cutting operation of the equipment and the convenience of subsequent maintenance.

[0040] The spacing adjustment mechanism 5 includes a guide groove 50 vertically penetrating through the left and right ends of the tool seat 40 and extending in the front-rear direction, and a side connecting plate 51 provided on the side of the mounting seat 44 and connected with the guide groove 50 by a stud bolt 52.

When the tool seat 40 vertically reciprocates under the driving of the driving unit 41, the guide plate 9 can stably slide along the guide rod 8, and the guide rod 8 can constrain the displacement of the tool seat 40 in the horizontal direction by means of the fixed support and the limiting effect on the guide plate 9, so as to ensure the perpendicularity of the movement track of the tool seat 40 and the tool 45, avoid cutting deviation caused by shaking of the tool seat 40 in the cutting process, and thus improve the precision and stability of the slitting operation.

[0043] The front side of the rack 1 is hingedly connected with an inspection window 10. The purpose of the above design is to set a plate-shaped inspection window 10 adapted to the opening of the working space on the front side of the rack 1, and the inspection window 10 is hingedly connected with the rack 1, and one side of the inspection window 10 is rotatably connected with the edge of the rack 1 through a hinge, so that the inspection window 10 can be flexibly opened and closed around the hinge. When the equipment needs to be inspected and the tool 45 needs to be replaced, the inspection window 10 can be directly opened, and the slitting mechanism 4, the pitch adjusting mechanism 5 and other components in the working space can be conveniently contacted; after the inspection is completed, the inspection window 10 can be closed to protect the working space, which is convenient for daily inspection and maintenance operation of the equipment, and can avoid foreign matters entering the working space or personnel touching the internal running components in the cutting operation, and can also consider the maintenance convenience and use safety.

[0044] In the embodiment, the rubber raw material to be cut is conveyed from the feeding platform 2 fixed on the rack 1 into the working space enclosed by the rack 1, placed on the support plate 6 at the bottom of the working space and below the tool holder 40, and the support plate 6 provides support for the part to be slitting of the raw material; if the slitting width needs to be adjusted, the double-headed bolt 52 connecting the side connecting plate 51 and the guide groove 50 of the tool holder 40 in the spacing adjustment mechanism 5 is loosened, the mounting seat 44 sleeved on the mounting rod 43 is pushed to slide along the mounting rod 43, the side connecting plate 51 on the side of the mounting seat 44 moves along the guide groove 50 extending in the front-back direction on the tool holder 40, and after the spacing between the adjacent cutters 45 is adjusted to the required specification, the double-headed bolt 52 is tightened to lock the side connecting plate 51 and the guide groove 50, thereby fixing the positions of the mounting seat 44 and the cutters 45; then the cylinder 410 installed on the top wall of the working space is started, the piston rod drives the tool holder 40 to vertically reciprocate, the guide plates 9 on the left and right sides of the tool holder 40 are sleeved with the vertical guide rods 8 on the left and right sides of the working space, the guide plates 9 slide along the guide rods 8 to constrain the horizontal displacement of the tool holder 40, and the movement track of the tool holder 40 is perpendicular; the cutters 45 on the tool holder 40 move synchronously with the tool holder 40 through the lower connecting plate 442 at the bottom of the mounting seat 44 and the bolt connection of the cutters 45, the cutter blade of the cutter 45 is embedded into the cutter slot 7 on the surface of the support plate 6 to complete the cutting of the raw material, and the cut rubber raw material is conveyed out of the working space from the discharge platform 3 opposite to the feeding platform 2; when the equipment needs to be overhauled, the internal slitting mechanism 4 is replaced with the cutter 45 or the parts are maintained, the plate-shaped maintenance window 10 can be opened around the hinge on the front side of the rack 1, and the operation is completed.
