In the semi-finished product processing step, the produced semi-finished rubber tubes are cut according to the designed size specifications to produce a large number of finished rubber tubes. The existing rubber tube semi-finished product processing devices generally have poor intelligence and rely on the proficiency of technicians for operation. After retrieval, the prior art (application number: CN202122788022.7) records "a rubber tube semi-finished product processing device, belonging to the technical field of rubber tube processing devices.

[0003] However, although the existing rubber tube semi-finished product processing device has achieved the effect of automatic cutting, there are still some deficiencies: the cutting knives involved in the existing rubber tube processing device, whether in linear switching or rotary cutting, all cut from one side of the outer wall of the rubber tube. The cutting end of the rubber block with a relatively thin wall thickness and soft material is generally in a suspended state, resulting in poor force stability during the cutting of the rubber tube and easy unevenness of the cut. Secondly, when the cutting knife is reciprocally moved up and down in a rotating state, not only is the structure complex, the equipment investment cost is high, but also its own stability cannot be guaranteed. Summary of the Utility Model

[0004] In order to overcome the defects existing in the prior art, a rubber tube processing device is provided to solve the problems of easy unevenness of the cut of the rubber tube and complex overall structure and high cost investment in the existing rubber tube processing device.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Referring to Figures 1 to 4 As shown, the present invention provides a rubber tube processing device, including: a turntable 1, a redirecting roller 2, a fixed block 3 and a cutter assembly 4. The turntable 1 is rotatably connected inside two fixed blocks 3, and the upper end of the fixed block 3 is connected to the redirecting roller 2 through a connecting column 21. And the outside of one of the fixed blocks 3 is connected with a motor 31. There are two fixed blocks 3, and a drive shaft 32 is rotatably connected between the fixed blocks 3. And one end of the drive shaft 32 is connected to the output shaft end of the motor 31. There are two groups of cutter assemblies 4, and both are connected to the edge of the turntable 1. The cutter assembly 4 includes a swing block 43 hinged to the turntable 1, and the outer end of the swing block 43 is connected with a cutting tool 42. At the same time, a spring 5 is connected between the swing blocks 43.

[0021] In this embodiment, the turntable 1, the redirecting roller 2, the fixed block 3 and the cutter assembly 4 constitute the main structure of the rubber tube processing device involved in this application, which is used for the cutting process during the processing of the rubber tube.

[0022] Specifically, the fixing block 3 is fixed by providing support legs at the bottom, thereby realizing the support for the turntable 1. A rubber tube conveying device identical to the prior art is provided at the rear side of the turntable 1, and at the same time, it is ensured that the rubber tube is in a horizontal state on the conveying device and in the guiding groove 11 of the turntable 1.

[0023] Specifically, the redirecting rollers 2 are respectively provided on both sides of the turntable 1, and the redirecting rollers 2 are rotatably connected to the connecting columns 21. At the same time, the redirecting rollers 2 are provided as a detachable structure.

[0024] As Figure 1 and Figure 2 As shown, a guiding groove 11 is formed at a peripheral edge of the turntable 1, and the rubber tube is slidably connected in the guiding groove 11. A notch 13 is formed at the outer edge of the turntable 1, and two groups of cutter assemblies 4 are both installed in the notch 13. At the same time, a limiting post 12 is fixed at the outer edge of the notch 13, and the limiting post 12 is located outside the swing block 43.

[0025] As a preferred embodiment, the notch 13 provides a reciprocating rotation space for the cutter assembly 4, and by providing the limiting post 12, the position where the swing block 43 expands outward is fixed.

[0026] As Figure 4 As shown, a tool holder 41 of an integral structure is provided at the outer end of the swing block 43, and the cutting tool 42 is fixed to the tool holder 41 by bolts. At the same time, abrasive discs 421 located in the same plane are embedded in the cutting surface of the cutting tool 42. The cutting tool 42 is provided as a wedge-shaped block structure, and the cuttings of the two cutting tools 42 intersect and fit with each other. A positioning hole 45 is formed inside the swing block 43, and a positioning pin 46 is provided in the positioning hole 45. At the same time, both ends of the spring 5 are inserted into the positioning hole 45. One end of the swing block 43 away from the cutting tool 42 is connected with a hinge shaft 44, and the hinge shaft 44 is rotatably connected to the turntable 1.

[0027] Specifically, the cutting tools 42 move closer to each other during cutting, and their inclined cutting surfaces slide in contact with each other, but do not touch the abrasive discs 421.

[0028] Specifically, the outer side of the tool holder 41 is provided as an inclined surface structure.

[0029] As a preferred embodiment, when the cutting tool 42 becomes blunt after long-term use, the redirecting roller 2 can be replaced with a roller having a larger outer diameter, so that when rolling and contacting the inclined surface on the outer side of the tool holder 41, the cuttings of the two cutting tools 42 can move to a farther position on the opposite side, so that the cutting edge contacts and rubs against the abrasive disc 421, realizing the grinding effect on the cutting edge.

[0030] It should be noted that during grinding, the cutting tool 42 does not cut the rubber tube, and the turntable 1 is in an idling state.

[0031] As a preferred embodiment, a spring 5 is provided to reset the cutter assembly 4 after cutting.

[0032] When in use, place the rubber tube in the guide groove of the turntable, then start the motor to drive the turntable to rotate, so that the conveyed rubber tube can be guided and limited, and the conveying stability of the rubber tube can be enhanced. At this time, during the rotation of the turntable of the two sets of cutter assemblies, when they are at the top of the turntable's rotation path, the inclined surface on the outside of the knife holder contacts the redirecting roller, so that the two sets of cutting knives are squeezed and moved closer to each other, and then the rubber tube is cut from two directions, so that the force of the rubber tube is balanced at the moment of cutting, reducing the probability of uneven cuts.

[0033] The rubber tube processing device of the utility model can effectively solve the problems of uneven cuts of rubber tubes, complex overall structure and high cost investment in existing rubber tube processing devices. It avoids the uneven cuts of rubber tubes on the basis of the existing rubber tube processing device technology, and has the advantages of simple structure and low cost investment.
