In addition, if the terms "first", "second", etc. appear in the description of the present utility model, they are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0019] In the description of the embodiments of the present utility model, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0020] As shown in the accompanying drawings, the utility model includes a slicing table 70, a feeding roller 71 is provided at the front end of the slicing table 70, an upper pressure roller 72 and a lower pressure roller 73 are provided at the rear end of the slicing table 70, and a cutting blade 74 linked to the lower pressure roller 73 is provided on the slicing table 70 located behind the upper pressure roller 72 and the lower pressure roller 73, and a cutting drive motor 75 is provided on one side of the slicing table 70 for driving the cutting blade 74 to move up and down.

[0021] The rubber sheet cooled by the open refining is laid flat on the slicing table 70 through the feed roller 71 in turn, and one end of the rubber sheet is clamped by the upper pressing roller 72 and the lower pressing roller 73. After the cutting drive motor 75 is started, the lower pressing roller 73 and the upper pressing roller 72 cooperate to transport the rubber sheet forward, and at the same time, the cutting blade 74 performs up and down cutting action to cut the passing rubber sheet into strips.

[0022] Furthermore, a support seat 77 is provided on both sides of the slicing table 70, and a knife holder 78 that can slide up and down is provided on the support seat 77, and the cutting blade 74 is adjustably mounted on the knife holder 78 through a set of screws; a vertical guide groove is provided on the support seat 77, and the two ends of the knife holder 78 are guided by the vertical guide groove to keep it moving vertically up and down. A detachable knife seat is provided on the cutting blade 74, one end of the screw is fixed to the knife seat, and a set of screw mounting holes is provided on the knife holder 78, and the other end of the screw passes through the screw mounting hole and is adjusted and fixed by a pair of nuts.

[0023] The tops of the two support seats 77 are connected by a rotating shaft 79, on which a pair of eccentric wheels 80 are provided, and on the eccentric wheel 80 a transmission connecting rod 81 for driving the tool holder 78 to move up and down is provided; the two ends of the rotating shaft 79 are respectively provided with a first flywheel 83 and a second flywheel 84, the cutting drive motor 75 drives the first flywheel 83 to rotate through a belt, and the second flywheel 84 drives the lower pressure roller 73 to rotate through a crank connecting rod mechanism 85.

[0024] When the eccentric wheel 80 rotates with the rotating shaft 79, the knife holder 78 is intermittently lifted up through the transmission connecting rod 81, thereby moving the cutting blade 74 up and down to perform the cutting action.

[0025] The crank-connecting rod mechanism 85 of the present case includes two cranks respectively connected to the lower pressure roller 73 and the second flywheel 84, and a connecting rod for connecting the two cranks. During the rotation of the second flywheel 84, the crank-connecting rod mechanism 85 drives the lower pressure roller 73 to rotate. Every time the lower pressure roller 73 rotates one circle, it can cooperate with the upper pressure roller 72 to transport the rubber sheet forward a certain distance.

[0026] Furthermore, a connecting rod adjustment seat 87 is provided on the second flywheel 84, and a screw slide 88 is provided on the connecting rod adjustment seat 87. One end of the connecting rod of the crank connecting rod mechanism 85 is rotatably connected to the slider of the screw slide 88. The specific position where the connecting rod of the crank connecting rod mechanism 85 is connected to the second flywheel 84 is adjusted by the screw slide 88, that is, the crank arm length of the crank connected to the second flywheel 84 is adjusted, so as to adjust the rotation speed of the lower pressure roller 73. The connecting rod length of the crank connecting rod mechanism 85 is an adjustable connection.

[0027] Further, the connecting rod adjustment seat 87 is provided with a scale ruler corresponding to the screw slide 88. The length of the crank arm connected to the crank on the second flywheel 84 can be adjusted intuitively and quickly through the scale ruler.

[0028] Further, the upper pressing roller 72 is movably mounted on the support seat 77 through a pair of vertical slides 89. The vertical slide 89 of this case is a manual screw slide for adjusting the height of the upper pressing roller 72.

[0029] Furthermore, a discharging slide 90 is provided at the rear end of the slicing table 70, so that the cut film can be smoothly discharged from the cutting position.

[0030] Furthermore, a powder box 91 is provided on the slicing table 70 below the feed roller 71. The feed roller 71 and the lower pressure roller 73 are both frosted rollers. The top of the powder box 91 is open, a part of the feed roller 71 is located in the powder box 91, and a material leveling brush 92 is provided on the top of the powder box 91, one end of which abuts against the roller surface of the feed roller 71.

[0031] When the feed roller 71 rotates, it will bring out the powder in the powder box 91. The powder is talcum powder. Since the feed roller 71 is a frosted roller, there are many small grooves on its surface. During the rotation of the feed roller 71, the material-leveling brush 92 will brush off the excess powder attached to the surface of the feed roller 71 and spread it evenly, while the powder that falls into the grooves will be retained. The rubber sheet is an elastic product. When passing through the surface of the feed roller 71, its own weight will cause the powder in the grooves to adhere to the bottom of the rubber sheet. After the rubber sheet is spread flat on the slicing table 70, a layer of powder adheres to the bottom, thereby reducing friction, making it easier for the rubber sheet to move forward smoothly on the slicing table 70 to avoid pulling and deformation.
