[0026] In order to enable those skilled in the art of this technology to better understand the solution of this utility model, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the drawings.

[0027] As Figures 1-4 shown, a rubber strip slitting device includes a hollow frame 1. Along the horizontal direction, a pressing plate assembly 2, a slitting cutter 3, a tensioning roller 4, a segmented conveyor belt 5, a segmented cutter 6, and a blanking conveyor belt 7 are sequentially arranged on the top of the frame 1. The pressing plate assembly 2 includes a hopper 21 and two pressing rollers 22. The hopper 21 is fixedly arranged on the frame 1. The two pressing rollers 22 are rotatably arranged below the lower port of the hopper 21 and are spaced apart along the horizontal direction. A guide roller 51 is rotatably arranged above the segmented conveyor belt 5, and the guide roller 51 is spaced from the segmented conveyor belt 5. The pressing rollers 22 are used to extrude the rubber material in the hopper 21 to make it into a sheet shape and then discharge it downward. The discharged sheet-shaped rubber material is divided into multiple rubber strips by the slitting cutter 3. The multiple rubber strips are guided to the segmented conveyor belt 5 through the tensioning roller 4. The guide roller 51 is used to press the rubber strips on the segmented conveyor belt 5 to prevent the rubber strips from shaking during transportation and ensure the neat transportation of the rubber strips. After passing through the segmented conveyor belt 5, the rubber strips are cut by the segmented cutter 6. The cut rubber strips are sent out through the blanking conveyor belt 7 and recovered by the corresponding recovery mechanism (such as a suction cup driven by a robotic arm), so as to complete the three steps of forming, strip cutting, and cutting of the rubber material on one device, realize the unified processing of the rubber strips, avoid frequent transfer of materials, and improve the production efficiency of the rubber strips.

[0028] In one embodiment, the slitting tool 3 may be composed of a plurality of cutters arranged side by side, and the cutters are all in contact with the nip roller 22 close to the tensioning roller 4 so as to cut the sheet rubber material transported to the tensioning roller 4 via the nip roller 22 into strips (not shown in the drawings).

[0029] Furthermore, a press motor 8 is provided in the same direction below the press roller 22, and a driving gear 81 is provided at the output end of the press motor 8. A press gear 83 is provided at the adjacent end of one press roller 22 and the driving gear 81. A first transmission gear 82 is rotatably provided between the driving gear 81 and the press gear 83. The lower side of the first transmission gear 82 is meshed with the driving gear 81, and the upper side of the first transmission gear 82 is meshed with the press gear 83. A tensioning gear 86 is provided at the rear end of the tensioning roller 4. A second transmission gear 84 and a third transmission gear 85 are rotatably provided between the tensioning gear 86 and the press gear 83 respectively. One side of the second transmission gear 84 is meshed with the press gear 83, and the other side of the second transmission gear 84 is meshed with the third transmission gear 85. The side of the third transmission gear 85 away from the second transmission gear 84 is meshed with the tensioning gear 86, and the two press rollers 22 are transmission-connected at one end away from the press gear 83.

[0030] In this embodiment, when the pressing motor 8 is started, its output end will drive the driving gear 81 to rotate, and the driving gear 81 will drive the pressing gear 83 to rotate through the first transmission gear 82, thereby driving the two transmission-connected pressing rollers 22 to rotate synchronously in the opposite direction, so as to extract the rubber material in the hopper 21 and extrude it into sheets. At the same time, the pressing gear 83 will drive the tensioning gear 86 to rotate through the second gear and the third gear, thereby synchronously driving the tensioning roller 4 to rotate, so as to convey the cut rubber strips to the segmented conveyor belt 5 through the tensioning roller 4, and use the tensioning wheel to tighten the rubber material between the pressing roller 22 and the segmented conveyor belt 5.

[0031] Furthermore, a first bevel gear 91 is provided at one end of the two pressing rollers 22 away from the pressing gear 83, and a transmission shaft 92 is rotatably provided on the frame 1. The transmission shaft 92 is adjacent to the first bevel gear 91 and is arranged along the connecting direction of the two pressing rollers 22. Second bevel gears 93 are provided at both ends of the transmission shaft 92 in a one-to-one correspondence with the first bevel gear 91. The second bevel gear 93 is meshed with the corresponding first bevel gear 91. When the pressing gear 83 drives one of the pressing rollers 22 to rotate, the corresponding first bevel gear 91 will rotate synchronously and drive the transmission shaft 92 to rotate through the corresponding second bevel gear 93. The transmission shaft 92 will drive the corresponding first bevel gear 91 to rotate through another second bevel gear 93, thereby driving the other pressing roller 22 to rotate synchronously in the opposite direction, so as to drive the two pressing rollers 22 to rotate synchronously.

[0032] Further, the strip cutter 3 includes a tool holder 31 and a plurality of circular blades 32. The tool holder 31 is fixedly connected to the machine frame 1. The plurality of blades 32 are all rotatably connected to the tool holder 31 and are distributed at intervals along the axial direction of the pressure roller 22. The ends of the blades 32 are all in contact with the pressure roller 22 close to the tension roller 4. The sheet-shaped rubber material formed by pressing through the pressure roller 22 is conveyed around the lower side of the pressure roller 22 close to the tension roller 4 towards the tension roller 4. At this time, the plurality of blades 32 will cut the rubber material and divide the rubber material into a plurality of rubber strips with uniform thickness. Moreover, the blades 32 can roll adaptively to ensure uniform wear of all parts of the blades 32 and extend the service life of the blades 32.

[0033] Further, the segment cutter 6 includes a cutter block 61, a lifting mechanism 62 and a cutting knife 63. The cutter block 61 is arranged between the segment conveyor belt 5 and the blanking conveyor belt 7, and the top surfaces of the three are flush. The lifting mechanism 62 is arranged above the cutter block 61. The cutting knife 63 is fixedly arranged at the movable end of the lifting mechanism 62. The lifting mechanism 62 can drive the cutting knife 63 to move downwards to contact the cutter block 61 or move upwards to disengage from the cutter block 61. During processing, the lifting mechanism 62 will regularly drive the cutting knife 63 to move downwards to contact the cutter block 61 and lift upwards to disengage from the cutter block 61, so as to cut off the rubber strip passing over the cutter block 61 and divide out rubber strips with the same length.

[0034] Further, the belt speed of the blanking conveyor belt 7 is greater than that of the segment conveyor belt 5, so as to quickly move the divided rubber strips by the blanking conveyor belt 7, ensure the separation of the divided rubber strips from the raw materials, and facilitate the quick recovery of the rubber strips.

[0035] Further, an operation panel 11 is arranged on one side of the machine frame 1. The operation panel 11 is electrically connected to the power ends of the pressure roller 22, the segment conveyor belt 5, the segment cutter 6 and the blanking conveyor belt 7 respectively. The user can control the operation of the pressure roller 22, the segment cutter 6, the segment conveyor belt 5 and the blanking conveyor belt 7 through the control panel.

[0036] Further, a stock preparation table 12 is arranged adjacent to the hopper 21 on the machine frame 1. The container containing the rubber material can be temporarily placed on the stock preparation table 12, so that the operator can gradually add the rubber material into the hopper 21.

[0037] Further, a plurality of foot cups are distributed circumferentially at the bottom of the machine frame 1, and a plurality of rollers are distributed circumferentially at the bottom of the machine frame 1. Under normal conditions, the foot cups will support the machine frame 1, separating the bottom wall of the rubber strip cutting device from the ground. When necessary, the user can also move the rubber strip cutting device through the rollers to adjust the placement position of the rubber strip cutting device.
