a bale cutter comprising:

a base 110;

in this embodiment, the base 110 includes two left and right side plates 110 and a connecting rod 111 connecting the two side plates 110; wherein, the two sides of the connecting rod 111 are welded and fixed with the two side plates 110.

The two side plates 110 are used as a supporting structure of the whole rubber cutting machine, and the thickness of the side plates can be selected according to specific conditions; the connecting rod 111 is used for connecting the two side plates 110, and the structural strength of the base 110 is improved.

The portal frame 120, the said portal frame 120 spans and fixes on base 110; the portal frame 120 comprises two side rods and a cross beam connected with the side rods, and the bottoms of the side rods are welded and fixed with the base 110.

The bedplate 140 is positioned below the cross beam of the portal frame 120 and welded on the base 110; a cutter groove 141 is arranged on the bedplate 140; the bedplate 140 is used for supporting the adhesive tape to be cut, so that the cutting operation of the cutter 160 is facilitated; the shape of the knife groove 141 is matched with the shape of the cutter head of the cutter 160.

And the hydraulic cylinder 150 is fixed on the beam of the portal frame 120, and a driving rod of the hydraulic cylinder penetrates through the beam of the portal frame 120 and extends downwards.

The guide posts 170 are fixed at the bottom of the beam of the portal frame 120 in a bilateral symmetry manner and are positioned on the inner side of the side lever of the portal frame 120; specifically, the guide posts 170 are welded to the bedplate 140 at the bottom and to the gantry 120 beam at the top.

In this embodiment, the guide post 170 is not a force-bearing structure of the hydraulic cylinder 150, and is mainly used to control the moving direction of the cutting knife 160.

The cutter 160 is fixed at the bottom of the driving rod of the hydraulic cylinder 150; two ends of the guide sleeve I161 are respectively welded, and the guide sleeve I161 slides on the guide column 170; the hydraulic cylinder 150 drives the rod to extend or contract, and drives the cutter 160 to move up and down in the height direction of the guide post 170.

The cutter head sheath 210 comprises a sheath 211 and a guide sleeve II 212;

the sheath 211 is positioned below the cutter 160, a cutter channel 211a is arranged at the middle position of the sheath 211 along the length direction of the sheath 211, and the cutter 160 can vertically penetrate through the cutter channel 211a;

in this embodiment, the sheath 211 may be formed by bending and welding a metal plate, or may be formed by machining with a milling machine, and is shaped like a long strip, and is mainly used to shield the tool bit of the cutter 160, thereby avoiding scratching the arm of a worker.

The guide sleeve II 212 is welded on the two sides of the sheath 211 left and right, and the guide sleeve II 212 slides on the guide column 170;

the spring 220 is sleeved on the guide post 170 and is positioned between the guide sleeve I161 and the guide sleeve II 212; the upper end of the guide sleeve is welded with the bottom of the guide sleeve I161, and the lower end of the guide sleeve I is welded with the top of the guide sleeve II 212;

wherein, under the non-compression state of the spring 220, the cutter head of the cutter 160 is accommodated in the cutter channel 211a of the sheath 211; even if the worker is not aware of the contact with the cutter 160 a little, the cutter head of the cutter 160 is not contacted.

It should be noted that the non-compressed state of the spring 220 can be understood as the non-operating state of the rubber cutting machine; at this time, the cutter 160 is not moved downward to compress the spring 220, and the spring 220 is only pulled downward by the weight of the bit guard 210.

In this embodiment, a plurality of positioning protrusions 211b are fixed at the bottom of the sheath 211 at intervals along the circumferential direction of the sheath 211; the positioning projections 211b are provided to improve the frictional force at the bottom of the cover 211.

When the rubber cutting machine works, the cutter 160 moves downwards and drives the sheath 211 to move downwards, the sheath 211 firstly contacts the rubber strip relative to the cutter 160 and presses and positions the rubber strip, and the rubber strip is prevented from moving in the cutting process; the positioning convex block 211b arranged at the bottom of the sheath 211 can improve the contact friction force between the sheath 211 and the adhesive tape, and avoid the displacement of the adhesive tape.

In this embodiment, the base 110 is provided with a conveying assembly at the front side and the rear side of the platen 140; specifically, the conveying assembly includes a plurality of conveying rollers 130 arranged at intervals; a transport roller 130 is provided for transporting the glue strip.

The embodiment of the utility model provides a pair of bale splitter protection principle as follows: FIG. 1 shows the bale cutter in a non-operating state; at this time, the blade of the cutter 160 is hidden and received in the cutter passage 211a of the sheath 211, and even if the worker does not touch the cutter 160, the worker does not touch the blade of the cutter 160, thereby protecting the safety of the worker.

The embodiment of the utility model provides a bale splitter working method as follows:

1. the worker places the adhesive tape on the platen 140 or sends the adhesive tape to the platen 140 through the conveying assembly;

2. the hydraulic cylinder 150 drives the rod to extend to drive the cutter 160 to move downwards; the sheath 211 moves downwards along the height direction of the guide post 170 under the driving of the cutter 160;

3. because the cutter 160 is hidden and accommodated in the cutter channel 211a of the sheath 211, the sheath 211 firstly contacts the adhesive tape relative to the cutter 160 and presses down and positions the adhesive tape, so that the adhesive tape is prevented from shifting in the cutting process;

4. the cutter 160 moves downwards continuously, the spring 220 is stressed and compressed, and the cutter head of the cutter 160 penetrates through the cutter channel 211a downwards to cut the adhesive tape;

5. after the cutting operation is finished, the hydraulic cylinder 150 drives the rod to contract to drive the cutter 160 to move upwards along the height direction of the guide post 170 for resetting; at this time, the spring 220 pushes out the sheath 211 under the action of the compression resilience force, so that the cutter 160 is hidden and accommodated in the cutter channel 211a of the sheath 211;

6. the hydraulic cylinder 150 drives the rod to continue to contract, and the cutter 160 and the sheath 211 synchronously move upwards to reset.

This with the novel bale splitter that embodiment provided, have following beneficial effect: the utility model discloses, through setting up the tool bit sheath, the bale splitter is under unoperated state, and the tool bit of cutter is hidden and is accomodate in the cutter passageway of sheath, protection workman's operation safety.
