Description

Technical Field

[0001] The utility model relates to the field of rubber cutting of a mixing machine, in particular to a rubber cutting device of a rubber mixing machine. Background Art

[0002] Mixing is the process of using a rubber mixer to mix raw rubber or plasticized raw rubber with compounding agents to make a rubber mixture. It is the most important production process in rubber processing. In essence, it is the process of uniformly dispersing the compounding agent in the raw rubber. The granular compounding agent is the dispersed phase and the raw rubber is the continuous phase.

[0003] Mixing refers to the process of adding various compounding agents, such as fillers, reinforcing agents, accelerators, vulcanizers, antioxidants, and anti-scorching agents, to raw rubber or plastic rubber in order to improve the physical and mechanical properties of rubber products, improve processing and molding technology, and reduce production costs. These compounding agents include solid and liquid materials. The various added compounding agents are evenly dispersed to ensure the consistency of the properties of the rubber compound.

[0004] During the mixing process, the raw rubber is squeezed between the heating rollers to perform the mixing. However, during the squeezing process of the heating rollers, the raw rubber is easily attached to the surface of the heating rollers. The continuously rotating heating rollers drive the flat raw rubber to rotate. At this time, the staff often needs to use a handheld cutting knife to cut and separate the raw rubber so that the circle is disconnected and then re-mixed. However, when cutting manually, since the raw material is in a rotating state, the staff needs to consume a lot of force during the cutting process due to the inertia generated by the rotation, and it is easy to cause safety hazards. Utility Model Content

[0005] Based on this, the purpose of the present invention is to provide a rubber cutting device for a rubber mixing machine to solve the technical problems mentioned in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rubber cutting device for a rubber mixing mill, comprising a mixing mill, a motor box fixedly mounted on one side of the mixing mill, and a reciprocating screw movably mounted on one side of the motor box, a collar sleeved on one end of the reciprocating screw, and a fixed block fixedly mounted on one side of the collar, a cutting knife movably mounted on one side of the fixed block, connecting blocks movably mounted on both sides of the mixing mill, and a limiting rod fixedly mounted on one side of the connecting block, the two groups of connecting blocks are connected by a limiting rod, a slot is provided in the middle of the cutting knife, and the slot cooperates with the limiting rod, a steel cable is mounted on one side of the connecting block, a pull rod movably mounted on one end of the mixing mill, and the pull rod and the connecting block are connected by a steel cable.

[0007] By adopting the above technical solution, the reciprocating screw rod and the ring can drive the cutting knife to move when the ring rotates. At the same time, by stepping on the foot pedal, the cutting knife can be moved to one side for a distance, so that the cutting knife can contact the raw rubber to complete the cutting. The cutting of the raw rubber is achieved by the retractable cutting knife. At the same time, when cutting is not required, the cutting knife is in a retracted state. At this time, the cutting knife will not contact the raw rubber, avoiding the impact of the cutting knife on the raw rubber during normal mixing. There is no need for manual cutting by the staff, which increases overall safety.

[0009] By adopting the above technical solution and setting a foot pedal, the cutting knife can be controlled to move telescopically, and by setting a steel cable and a pulley, stepping on the foot pedal can be more labor-saving, making the overall movement smoother.

[0010] The utility model is further configured such that a second spiral groove is provided at the other end of the screw rod, and a supporting plate is movably installed at one end of the mixer, a telescopic rod is fixedly installed at one end of the supporting plate, and a guide rod matching the second spiral groove is installed inside the telescopic rod.

[0011] By adopting the above technical solution, by setting a spiral rod and a second spiral groove, when the spiral rod rotates, the setting of the second spiral groove can be used to move the guide rod inside the telescopic rod upward, thereby raising the supporting plate. When the supporting plate is raised, the raw rubber falls to the surface of the supporting plate, so that the staff can pick up the cut raw rubber without bending over, and the overall work efficiency is higher and more convenient.

[0012] The utility model is further configured such that a second spring is installed on one side of the connecting block, and the connecting block and the mixer are connected via the second spring; a heating roller is movably installed on one end of the mixer, and a heating drive device is provided on one end of the heating roller.

[0013] By adopting the above technical solution and providing the second spring, the connecting block has enough force to reset, so that the overall work can be completed stably and reset, which is more convenient for the next cutting work.

[0014] The utility model is further configured such that a first spring is installed at one end of the foot pedal, and the foot pedal is connected to the mixer through the first spring, limiting blocks are fixedly installed on both sides of the foot pedal, and limiting grooves cooperating with the limiting blocks are opened on both sides of the mixer.

[0015] By adopting the above technical solution, by setting the first spring, the foot pedal can automatically reset under the action of the first spring when it is not under pressure.

[0017] By adopting the above technical solution and setting a slider, the movement of the carrying plate is limited. At the same time, by setting the slide groove, the slider can move more smoothly, reduce friction, and save effort.

[0018] In summary, the present invention has the following beneficial effects:

[0019] The utility model uses a reciprocating screw rod and a sleeve ring, and when the sleeve ring rotates, it can drive the cutting knife to move. At the same time, by stepping on the foot pedal, the cutting knife can be moved to one side for a distance, so that the cutting knife can contact the raw rubber to complete the cutting. The cutting of the raw rubber is achieved by the retractable cutting knife. At the same time, when cutting is not needed, the cutting knife is in a retracted state, and the cutting knife does not contact the raw rubber at this time, avoiding the cutting knife from affecting the raw rubber during the normal mixing process. There is no need for manual cutting by the staff, which increases the overall safety and saves more labor. By arranging the spiral rod and the supporting plate, when the foot pedal moves downward, the spiral rod can be rotated, thereby causing the telescopic rod to move upward, lifting the supporting plate, and one end of the raw rubber falls after the cutting is completed. At this time, the raw rubber can fall onto the surface of the supporting plate, which is more convenient for the staff to take, thereby increasing the overall work efficiency.

[0035] The working principle of the utility model is as follows: the driving device on one side of the heating roller 25 is started to rotate the heating roller 25, thereby adding raw rubber for mixing; when the raw rubber needs to be cut, the foot pedal 16 is stepped on to move the foot pedal 16 downward, thereby squeezing the first spring 18; when the foot pedal 16 moves downward, the guide block 17 is driven to move; when the guide block 17 is moved, the guide block 17 squeezes the first spiral groove 14, thereby causing the screw rod 13 to rotate; when the screw rod 13 rotates, the gear plate 12 is driven to move to one side through the gear meshing, and at the same time, the pull rod 11 is pulled to move to one side; when the pull rod 11 is pulled, the steel cable 9 is displaced, thereby 0, the connecting block 8 moves to one side. When the connecting block 8 moves, it drives the limit rod 7 to move, thereby pushing the cutting knife 6 to move. At this time, the motor box 2 is started to rotate the reciprocating screw rod 3. Since a threaded groove that cooperates with the reciprocating screw rod 3 is provided inside the collar 4, when the reciprocating screw rod 3 rotates, it drives the collar 4 to move, and horizontal cutting is performed at this time. When the spiral rod 13 rotates, the guide rod inside the telescopic rod 15 slides in the second spiral groove 141. At this time, the telescopic rod 15 moves up. When the telescopic rod 15 moves up, it drives the carrying plate 20 to move up. At this time, the raw rubber dropped by the cutting can fall above the rising carrying plate 20, which is more convenient for the staff to take it.
