Technical Field

[0001] This utility model relates to the field of tire manufacturing technology, specifically to an automatic slitting machine for the sidewall triangular rubber. Background Technology

[0002] The triangular rubber components produced in the semi-finished product workshop are made by extruding two different types of rubber materials using two extruders of different specifications. These two materials are then bonded together using a pre-die and die plate. However, some waste material is inevitably generated during actual production. This waste material needs to be slit and returned to the previous process mixing workshop for reprocessing, mainly to ensure the consistency of the rubber materials and guarantee product quality. Currently, slitting the waste material typically requires 6-8 people operating simultaneously, resulting in low efficiency and certain safety risks. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An automatic sidewall triangular rubber slitting machine includes a frame, a pallet inclinedly mounted on the frame, a conveyor roller at the downstream end of the pallet, a slitting device above the conveyor roller, the slitting device being fixed to the frame, the slitting device including a blade holder, a blade base below the middle of the blade holder, a cutting blade installed inside the blade base, the blade base being driven up and down by a cylinder, the cylinder being fixed to the top of the blade holder.

[0006] Preferably, the conveyor roller has a cutting groove, which corresponds to the position of the cutting blade.

[0007] Preferably, two positioning plates are arranged side by side on the top surface of the tray, and the positioning plates are detachably connected to the tray.

[0008] Preferably, the conveyor roller is driven to rotate by a motor, which is fixed to one side of the frame.

[0009] Preferably, locating pins are symmetrically arranged on both sides of the cylinder, and the bottom of the locating pins is connected to the tool holder.

[0010] Preferably, the cutting blade has a tapered structure.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: by using the slitting machine of this utility model to slit triangular rubber waste, the cutting efficiency and cutting accuracy are high, only two people are needed to complete the slitting operation, and the safety is also greatly improved. Attached Figure Description

[0012] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments recorded in this utility model. For those skilled in the art, other drawings can be obtained based on these drawings.

[0016] The invention will now be described in detail with reference to the accompanying drawings, by way of example. Obviously, the described embodiments are only some embodiments of the invention, and not all embodiments. Example

[0017] like Figure 1 As shown, this utility model discloses an automatic sidewall triangular rubber slitting machine, including a frame 1. A pallet 2 is inclinedly mounted on the frame 1. Two positioning plates 9 are arranged side-by-side on the top surface of the pallet 2 to position the material movement. The positioning plates 9 are detachably connected to the pallet 2, allowing for easy adjustment of the distance between the two positioning plates 9 according to the material width, enabling positioning and conveying of materials of different widths and ensuring slitting accuracy. A conveying roller 3 is provided at the downstream end of the pallet 2. The surface of the conveying roller 3 is knurled to increase friction. A cutting groove 8 is formed on the conveying roller 3. The conveying roller 3 is driven to rotate by a motor 10, which is fixed to one side of the frame 1. To prevent special circumstances... In case of an accident, an emergency stop button is also provided on the frame 1 for emergency braking of the conveyor roller 3; a slitting device is provided above the conveyor roller 3, and the slitting device is fixed on the frame 1. The slitting device includes a gantry-shaped knife holder 4, and a knife seat 5 is provided below the middle of the knife holder 4. A cutting knife 6 is installed in the knife seat 5. The cutting blade of the cutting knife 6 has a conical structure, and the cutting knife 6 is positioned corresponding to the cutting groove 8; the knife seat 5 is driven to move up and down by a cylinder 7, which is fixed on the top of the knife holder 4. Positioning pins 11 are symmetrically arranged on both sides of the cylinder 7. The bottom of the positioning pins 11 is connected to the knife seat 5 to prevent the knife seat 5 from shifting during movement, which would cause deviation during slitting.

[0018] Working principle: During use, a worker places the discarded triangular rubber from the upstream end of the pallet 2 between the two positioning plates 9, and at the same time applies a downward pushing force to make the triangular rubber move towards the conveyor roller 3. During the conveying process, the cylinder 7 extends and drives the cutter holder 5 to move downward until the cutting blade 6 inside the cutter holder 5 contacts the cutting groove 8 on the conveyor roller 3. Driven by the conveyor roller 3, the triangular rubber is cut into two pieces by the cutting blade 6 and then pulled by another worker to the subsequent conveying device, which transports it to the material stacking area.

[0019] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and application concept of the present utility model, should be included within the protection scope of the present utility model.
