[0002] Rubber hose refers to the pipe used for gas transmission, which is commonly used in gas welding, gas cutting, various gas shielded welding, plasma arc welding and cutting, etc. In the automobile manufacturing industry, rubber hose is one of the most common and widely used parts. In the daily production process, the corresponding rubber extruder is usually used to extrude the rubber hose, and then cut it into sections according to the length requirements.
[0003] In practice, the space required for cutting the rubber tube after linear extrusion and transportation is often large, but the space in the production plant is limited, so it is difficult to meet the needs of the above-mentioned linear transportation and cutting in terms of space. This requires turning during transportation and then cutting. Summary of the invention
[0004] In order to meet the above-mentioned demand for turning cutting of rubber tubes, the present invention proposes a turning cutting system and method for rubber mold extrusion.
[0005] The technical problem to be solved by the present invention is achieved by adopting the following technical solutions:

The extruder is located on the left side of the type I conveyor belt, and can gradually extrude the rubber tube onto the type I conveyor belt. The turning double frame can limit the movement and transportation of the extruded rubber tube. The turning control system is used to control the turning of the extruded rubber tube, and the cutting controller is used to cut the rubber tubes one by one after the turning.
[0007] The right part of the turning double frame is in an arc shape; the turning double frame is provided with a fixed loading part fixedly installed on the tooling table. Specifically, the right part of the turning double frame is against the II type conveyor belt, and the left part of the turning double frame is in a straight line shape, and the left part of the turning double frame is respectively against the upper end of the I type conveyor belt and the upper end of the III type conveyor belt.
[0008] The type I conveyor belt is parallel to the type III conveyor belt; the type I conveyor belt abuts against the left front part of the type II conveyor belt; the type III conveyor belt abuts against the left rear part of the type II conveyor belt. The above is the orientation relationship of the three conveyor belts.
[0009] Type I conveyor belts, Type II conveyor belts and Type III conveyor belts are all connected to two wide belt wheels, and each wide belt wheel is connected to a belt shaft mounted on the workbench 1 through a bearing seat. The above is a conventional design of a conveyor belt structure.
[0010] The belt shaft corresponding to the left side of the I-type conveyor belt is connected to an I-type motor installed on the tooling table. That is, the I-type motor is the conveying drive source.
[0011] The beneficial effects of the present invention are:
[0012] 1. It can stably control the directional transportation of the three conveyor belts and the guiding function of the turning double frames, which can effectively control the rubber tube to make a 180-degree turn and effectively solve the problem of equipment space utilization.
[0013] 2. Relying on two guide wheels, the rubber tube can be transported along a predetermined trajectory, effectively ensuring the turning and cooling of the rubber tube.

The extruder 2 is located on the left side of the type I conveyor belt 3, and can gradually extrude the rubber tube onto the type I conveyor belt 3. The turning double frame 6 can limit the movement and transportation of the extruded rubber tube. The turning control system is used to control the turning of the extruded rubber tube, and the cutting controller is used to cut the rubber tubes one by one after the turning.
[0023] like Figure 1 As shown, the right part of the turning double frame 6 is in an arc shape; the turning double frame 6 is provided with a fixed loading part 6a fixedly mounted on the workbench 1. Specifically, the right part of the turning double frame 6 is in contact with the II type conveyor belt 4, and the left part of the turning double frame 6 is in a straight line shape, and the left part of the turning double frame 6 is in contact with the upper end of the I type conveyor belt 3 and the upper end of the III type conveyor belt 5 respectively.
[0024] like Figure 1 As shown, as another improvement of the present invention, in order to ensure that the rubber tube can be stably transported on the right side of the turning double frame 6, a set of guide wheels 25 No. 1 can be installed on the right side wall of the turning double frame 6.

The above is the orientation relationship of the three conveyor belts.
[0026] like Figure 1 and Figure 2 As shown, the type I conveyor belt 3, the type II conveyor belt 4 and the type III conveyor belt 5 are all connected to two wide belt wheels 8, and each wide belt wheel 8 is connected to a belt shaft 9 installed on the workbench 1 through a bearing seat. The above is a conventional design of a conveyor belt structure.
[0027] like Figure 2As shown, the belt shaft 9 corresponding to the left side of the I-type conveyor belt 3 is connected to an I-type motor 10 installed on the tooling table 1. That is, the I-type motor 10 is a conveying drive source.
[0028] like Figure 2 As shown, the belt shafts 9 corresponding to the left sides of the type I conveyor belt 3 and the type III conveyor belt 5 are both connected with type I bevel gears 11; the two type I bevel gears 11 are both meshed with type II bevel gears 12; the type II bevel gears 12 are connected with a central shaft 13 installed on the workbench 1 through a bearing. That is, through the transmission of the bevel gears, the conveying directions of the type I conveyor belt 3 and the type III conveyor belt 5 can be opposite.
[0029] like Figure 1 and Figure 3 As shown, the belt shaft 9 corresponding to the right side of the type I conveyor belt 3 and the belt shaft 9 corresponding to the front side of the type II conveyor belt 4 are both connected with narrow belt wheels 14; a rope belt 15 is provided between the two narrow belt wheels 14 to connect the two belt wheels; a cylindrical block 16 is installed on the workbench 1 to abut against the middle of the rope belt 15. That is, through the transmission of the rope belt 15, the type II conveyor belt 4 can also perform the transmission work synchronously.
[0030] like Figure 1 and Figure 4 As shown, the cooling pool 7 is placed on the workbench 1 and abuts against the left end of the type III conveyor belt 5; the cutting assembly includes an execution seat 17 fixedly mounted on the workbench 1 and a type II motor 18, a vertical rod 19, and a spring 20 all mounted on the execution seat 17; the rear of the execution seat 17 is provided with an anvil portion 17a abutting against the cooling pool 7. The extruded rubber tube will be transported by the type I conveyor belt 3, the type II conveyor belt 4, and the type III conveyor belt 5 in turn into the cooling pool 7 for cleaning and cooling, and then moved to the anvil portion 17a for subsequent cutting.

The linear rack 21 is connected to the spring 20; a guide guard plate 24 is installed on the anvil portion 17a. A clearance groove is provided in the middle of the guide guard plate 24 to prevent interference with the segmentation knife 22. That is, the cylindrical wheel 23 is controlled to rotate one circle to complete the sequential cutting task. That is, when the spur gear group 23a meshes with the linear rack 21, the segmentation knife 22 moves downward to perform cutting. When the spur gear group 23a is disengaged from the linear rack 21, the segmentation knife 22 rises and resets under the action of the spring elastic force.

[0034] Step 1: Extrude the rubber tube through the extruder 2.
[0035] Step 2: When the type I motor 10 rotates clockwise and is driven by the bevel gear and the rope, the extruded rubber tube can be sequentially driven by the type I conveyor belt 3, the type II conveyor belt 4 and the type III conveyor belt 5, and the guiding effect of the turning double frame 6 can make the extruded rubber tube rotate 180 degrees and be transported to the cooling pool 7 for cleaning and cooling.
[0036] Step 3: After passing through the cooling pool 7, the rubber tube is conveyed to the anvil portion 17a through the guide guard plate 24. Under the premise of the conveyor belt and the extruder being braked, the cylindrical wheel 23 is driven to rotate by the II-type motor 18 to control the automatic cutting of the rubber tube.
