Description

Technical Field

[0001] The utility model relates to the technical field of tire rubber belt trimming, in particular to a rubber belt cutting tool. Background Art

[0002] There are always certain manufacturing defects in the rubber belt of tire products, such as rough edges, excess rubber edges or wide rubber belt surfaces. Therefore, the rubber tire skin needs to be trimmed during the tire processing.

[0003] There are two main traditional methods: one is to use a pressure strip to press and fix the rubber sheet, and then press down the guillotine to cut the rubber sheet; the disadvantage of this cutting method is that the force area of ​​the rubber sheet is too large, and the cutting force is relatively dispersed, which may easily cause the rubber sheet to be deformed around the cutting. If the density of the rubber sheet is uneven, for example, when other mixtures are added inside, the "broken lotus root" phenomenon may occur; the other is to use a disc knife on the transmission line to cut the rubber sheet from one end to the other end. If there is a close contact between the rubber sheet and the table on which the rubber sheet is laid during the cutting process, the friction is large and it cannot be cut continuously, which may cause the disc knife to pull the rubber sheet and cause the cross section of the rubber sheet to deform, resulting in the phenomenon that the cut section of the rubber sheet is uneven. It can be seen from the above cutting methods that the traditional cutting technology requires manual operation to position the rubber sheet and the cutter when cutting the rubber sheet. Positioning and cutting is time-consuming and labor-intensive, inefficient, and the yield rate of the cut rubber sheet is low. Utility Model Content

[0023] Example 1

[0024] Please refer to Figure 1-Figure 4 shown.

[0025] The utility model provides a rubber belt cutting tool, such as Figure 1 , Figure 2As shown, it includes a mounting base 7 mounted on a transmission line frame 1, a tool holder 9 is rotatably provided on the mounting base 7, a tool 11 is installed on one end of the tool holder 9 close to the transmission surface of the transmission line, and a positioning component is provided on the mounting base 7 for driving the tool holder 9 to rotate relative to the transmission surface of the transmission line. The rubber belt 12 cutting tool 11 provided in the utility model mainly solves the problem in the prior art that when the tool 11 cuts the rubber belt 12 during the transmission process, the rubber sheet is easily deformed around the cut piece and the cutting accuracy cannot be guaranteed; and the existing tool 11 has a vertical cutting edge after cutting the rubber. In the later tire manufacturing process, the bonding strength between rubber and rubber is not good, which is not conducive to the molding of the tire and the performance after bonding; in order to solve the above problems, the technical scheme rotates the tool holder 9 equipped with the tool 11 on the mounting base 7, and provides a positioning component on the mounting base 7 for adjusting the rotation of the tool holder 9 relative to the mounting base 7, so that the tool 11 can be deeply inserted into the rubber belt 12 on the conveyor belt to cut it. At the same time, the tool 11 in an inclined state is used to cut a groove on the conveyor belt, which is beneficial to the later tire manufacturing process. The bonding strength between rubber and rubber is increased through the groove, thereby ensuring the molding quality of the tire product.

[0026] Preferably, the tool 11 is installed in the tool 11 installation notch on the tool holder 9 by means of screws, thereby increasing the connection strength between the two.

[0027] In some technical solutions of the utility model, the positioning assembly includes a screw rod 17 rotatably arranged on the mounting base 7, a displacement seat 3 threadedly connected thereto is sleeved on the screw rod 17, the displacement seat 3 contacts the side wall of the mounting base 7, a linkage rod 14 is rotatably arranged on the displacement seat 3 through a pin, and the free end of the linkage rod 14 is hinged to the tool holder 9 through a pin. The screw rod 17 is mounted on the mounting base 7 through a rotating shaft seat, the displacement seat 3 sleeved on the screw rod 17 is threadedly connected thereto, the displacement seat 3 can move toward the direction close to the tool holder 9 under the dual restrictions of the screw rod 17 and the mounting base 7, and the linkage rod 14 is used to force the tool holder 9 to rotate on the mounting base 7, thereby changing the inclination angle of the tool 11 located on the tool holder 9 relative to the rubber belt 12, cutting grooves of different angles on the conveyor belt, and increasing the adaptability of the tool 11; it is beneficial to increase the bonding strength between rubber and rubber through the groove in the later tire manufacturing process, and ensure the molding quality of the tire product.

[0028] In some technical solutions of the utility model, a column 6 is installed on the transmission line frame 1 in the vertical direction, and a mounting opening adapted to the column 6 is provided on the mounting base 7, and a locking rod 15 detachably connected to the column 6 is penetrated in the mounting opening. The column 6 provides support for the mounting base 7, so that the cutting tool 11 can ensure its cutting accuracy when cutting the rubber belt 12. The locking rod 15 is a screw rod 17 rotatably arranged on the mounting base 7, the screw rod 17 is threadedly connected to the internal threaded hole provided on the mounting base 7, and a part of the screw rod 17 is embedded in a blind hole provided on the column 6.

[0029] In some technical solutions of the utility model, a plurality of slide grooves are provided on the side wall of the column 6 in the horizontal direction, and the plurality of slide grooves are evenly arranged along the extension direction of the column 6, and a convex strip 16 adapted to the slide groove is provided on the inner wall of the installation opening.

In this way, when adjusting the cutting width of the rubber belt 12, the installation base 7 can be pulled on the column 6 to move in the horizontal direction (i.e., move in the width direction of the rubber belt) to cut out the rubber belt 12 of a suitable width, thereby improving the adaptability of the device.

[0030] Preferably, the mounting base 7 can be completely pulled out from the column 6 to redetermine the mounting height of the mounting base 7 so as to adapt to the cutting of rubber belts 12 of different thicknesses.

[0031] In some technical solutions of the utility model, the column 6 is inserted through the transmission line frame 1 and extends outward, and the transmission line frame 1 is provided with an electric push rod 2 connected to the column 6 through a socket. The above structure is conducive to re-determining the installation height of the installation base 7, so as to adapt to the cutting of rubber belts 12 of different thicknesses.

[0032] The column 6 is inserted through the transmission line frame 1 and then extends outward. The transmission line frame 1 can be used to guide the movement of the column 6 to ensure the installation accuracy of the installation base 7.

[0033] In some technical solutions of the utility model, a rotating disk 4 is provided at one end of the screw rod 17 away from the tool holder 9, and a handle 5 is provided on the rotating disk 4. It is convenient for the operator to adjust the inclination angle of the tool holder 9 on the mounting base 7, cut grooves of different angles on the rubber belt 12, and increase the adaptability of the tool 11.
