Detailed Description

For further understanding of the present invention, the present invention will be described in detail with reference to the following examples, which are provided for illustration of the present invention but are not intended to limit the scope of the present invention.

Referring to fig. 1, a rubber cutting device of a rubber mixing machine comprises a support shaft 1, a connecting seat 2 and two cutter assemblies 3, wherein the connecting seat 2 and the two cutter assemblies are respectively and fixedly installed on the left side and the right side of a rubber mixing machine frame (the structure is common in the prior art and is not shown here). Two ends of the supporting shaft 1 are respectively erected on the left connecting seat and the right connecting seat 2. Referring also to fig. 7, the support shaft 1 is located below the rear side of the driven roller 10, and the support shaft 1 is parallel to the driven roller 10 of the rubber mixing machine. Referring to fig. 5, the support shaft 1 includes a support shaft body 11 and connectors 12 fixedly connected to two ends of the support shaft body 11, and a diameter of each connector 12 is smaller than a diameter of the support shaft body 11.

Referring to fig. 1 and 2, two cutter assemblies 3 are mounted on the support shaft 1 at intervals, each cutter assembly 3 includes a shaft sleeve 4, a cutter seat 5, a cutter 6 and two positioning bolts 7, the inner diameter of the shaft sleeve 4 is slightly larger than the outer diameter of the support shaft 1, and the shaft sleeve 4 is sleeved on the support shaft 1 and can translate on the support shaft 1. It is worth mentioning that the cutter assembly 3 of the present invention is usually made of iron material with a certain dead weight. Referring to fig. 3, the tool holder 5 is substantially rectangular, one end of the tool holder 5 is fixed to one side surface of the shaft sleeve 4, and the other end of the tool holder 5 forms a free end, and the thickness of the tool holder 5 is smaller than the height of the shaft sleeve 4. As can be seen from fig. 3, the tool holder 5 includes a bottom plate 51 and two side bars 52 extending along the length direction of the bottom plate 51, the side bars 52 are respectively fixed on the upper and lower sides of the bottom plate 51, and two assembling holes 53 are opened on the center line of the bottom plate 51 in the length direction; the base plate 51 and the two side bars 52 together form a rectangular mounting slot (not shown).

Referring to fig. 2 and 4, the use state of the cutting knife 6 is taken as the standard, the cutting knife 6 includes a connecting portion 61 at the rear end and a blade portion 62 at the front end, the connecting portion 61 and the blade portion 62 are integrally formed (both are bounded by dotted lines in the figure), a strip-shaped blade 63 is disposed on the lower side surface of the blade portion 62, the connecting portion 61 is rectangular, the width of the connecting portion is slightly smaller than the distance between the two side stop bars 52, and the connecting portion is clamped in the mounting groove. A long strip-shaped through hole 64 is formed in the length direction of the connecting part 61; each positioning bolt 7 extends into both the through hole 64 and the corresponding fitting hole 64. When the length of the cutter component 3 needs to be changed, the positioning bolt 7 only needs to be screwed out, then the cutter 6 and the cutter holder 5 are relatively displaced, and after the position is determined, the cutter 6 and the cutter holder 5 are repositioned by the positioning bolt 7.

With continued reference to fig. 1 and 3, a threaded hole 41 is formed in an opposite side surface of the sleeve 4, which is opposite to the side surface of the sleeve where the tool holder 5 is located; the cutter assembly 3 further comprises a first bolt 42, and the first bolt 42 can be screwed into the threaded hole 41.

Referring also to fig. 4, the length of the upper side 65 of the blade part 62 is smaller than the length of the lower side 66 of the blade part 62, and the blade part 62 has an arc-shaped front side 67, and one end of the front side 67 is connected to the upper side 65 and the other end is connected to the lower side 66.

Referring to fig. 6, the connecting socket 2 includes a connecting socket body and a second bolt 21, the connecting socket body includes a left vertical block 22, a lower horizontal block 23, a right vertical block 24 and an upper horizontal block 25 which are integrally formed, the left vertical block 22 and the right vertical block 24 are respectively connected to the left end and the right end of the lower horizontal block 23, one end of the upper horizontal block 25 is connected to the upper end of the right vertical block 24, the other end forms a free end, the free end and the left vertical block 22 are separated from each other, and the left vertical block 22, the right vertical block 24, the upper horizontal block 25 and the lower horizontal block 23 together form an L-shaped mounting hole 20; the connector 12 of the support shaft 1 is arranged in the mounting hole 20; the second bolt 21 is inserted into the left vertical block 22, and the end of the second bolt 21 abuts against the connecting head 12. When the supporting shaft 1 needs to be disassembled, the supporting shaft 1 can be taken out along the mounting hole 20 only by screwing out the second bolt 21, so that the disassembling is very convenient.

Because the shaft sleeve 4 can not only move on the supporting shaft 1, but also rotate on the supporting shaft 1, the distance and the angle of the two cutter assemblies 3 can be adjusted at will, and when the driven roller 10 moves, the length of the cutter assemblies 3 can be correspondingly adjusted through the adjustment of the positioning bolts 7 so as to meet the requirement of actual processing. Fig. 7 is a schematic structural diagram of the cutter assembly 3 during operation, and it can be seen that the front end of the blade portion 62 abuts against the side surface of the driven roller 10, and since the dead weight of the cutter assembly 3 (iron) is relatively large, it can be firmly pressed against the driven roller 10, so that when the driven roller 10 moves counterclockwise, the colloid on the driven roller 10 can be cut, and the leftover material can be effectively removed.

The present invention has been described in detail with reference to the embodiments, but the description is only for the preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. All the equivalent changes and improvements made according to the application scope of the present invention should still fall within the patent coverage of the present invention.
