[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] In order to solve the problems of complex operation and poor tire molding effect of tire production systems and tire production processes in the prior art, the present invention provides a tire production system and tire production process.

[0025] like Figure 1 and Figure 2 As shown, the tire production system includes a molding machine 10 and a cushion rubber production device 20 . The cushion rubber production device 20 is located upstream of the molding machine 10 and is used to continuously produce cushion rubber and directly deliver it to the molding machine 10 .

[0026] In the present application, the cushion rubber production equipment 20 is directly arranged upstream of the molding machine 10. In this way, the cushion rubber production equipment 20 continuously produces cushion rubber and directly conveys it to the molding machine 10, eliminating the process of winding the produced cushion rubber to form a material roll, and correspondingly eliminating the process of guiding the material roll open, thereby avoiding deformation of the cushion rubber during the winding and guiding process, thereby eliminating the need to set up a semi-finished product workshop, reducing the occupied area of ​​the tire production system, and eliminating the need for material roll transportation, which can reduce the labor intensity of workers and save a lot of manpower and materials. Accordingly, the tire production process is simplified, the molding quality of the tire is improved, and when changing product specifications, it is only necessary to directly control the size of the cushion rubber produced by the cushion rubber production equipment 20, thereby realizing the use requirements of small-batch flexible production of tires.

[0027] like Figure 1 As shown, the cushion rubber production equipment 20 includes an extruder 21, a storage device 22, a cooling device 23, a cutting device 24 and a feeding rack 25. The extruder 21 is used to extrude the cushion rubber. The storage device 22 is located downstream of the extruder 21 and is used to store the cushion rubber. The cooling device 23 is located between the extruder 21 and the storage device 22 and is used to cool the cushion rubber and transport the cushion rubber from the extruder 21 to the storage device 22. The cutting device 24 is located downstream of the storage device 22 and is used to cut the cushion rubber into two cushion rubber strips. The feeding rack 25 is located downstream of the cutting device 24 and is used to provide cushion rubber strips for the molding machine 10.

[0028] In this way, the cushion rubber production equipment 20 is used to extrude, cool and store the cushion rubber online and apply it to the molding machine 10.

[0029] Optionally, the cushion rubber production equipment 20 further includes a contour sensor, which is disposed between the extruder 21 and the cooling device 23 and is used to detect the size of the cushion rubber extruded by the extruder 21 .

[0030] Optionally, the pad rubber production equipment 20 also includes a controller, which is electrically connected to the extruder 21. The contour sensor is arranged close to the extruder 21 relative to the cooling device 23, so as to detect the size of the pad rubber extruded by the extruder 21 earlier. When the size of the pad rubber does not meet the requirements, the contour sensor can detect it more promptly and feed back the detection result to the controller. The controller makes corresponding adjustments to the size of the pad rubber extruded by the extruder 21 according to the feedback result, thereby realizing automatic feedback closed-loop control of the extruder 21 and ensuring the stability of the size of the pad rubber.

[0031] Optionally, the extruder 21 is a gear pump extruder, which can improve the dimensional accuracy of the product, achieve accurate control of the output, and achieve precise extrusion of the cushion rubber. In this way, the mixed rubber is fed into the extruder 21 through the feeding port of the extruder 21, and the mixed rubber is quantitatively extruded through the gear pump after plasticization, and the cushion rubber of the qualified size is obtained through the die head.

[0032] When the size or shape of the rubber pad needs to be adjusted by changing the specifications, it can be achieved by changing the die head.

[0033] Optionally, the cooling device 23 includes a housing and a motor, the rubber pad is overlapped on the outer side of the housing, a refrigerant is provided in the housing, and the motor drives the housing to rotate to transport the rubber pad overlapped on the housing to the storage device 22.

[0034] Optionally, the refrigerant is cooling water that circulates into the shell.

[0035] Optionally, the cooling device 23 is a small cooling drum. In a specific embodiment of the present application, a small cooling drum with a diameter of 200 mm is selected. In this way, the cooling device 23 occupies a small area, thereby reducing the overall area occupied by the cushion rubber production equipment 20, which is conducive to realizing the miniaturization design of the tire production system.

[0036] Optionally, the cooling device 23 further includes a controller, which is used to control the speed of the motor so that the speed of the motor matches the discharge speed of the extruder 21.

The controller adjusts the distance between the upper beam 221 and the lower beam 222 according to the detection result of the laser sensor. Specifically, the longer the distance between the upper beam 221 and the lower beam 222 is, the longer the length of the cushion rubber that can be stored is. In this way, the production speed of the cushion rubber is comprehensively considered, and the distance between the upper beam 221 and the lower beam 222 is adjusted to ensure tension-free storage of the cushion rubber.

[0038] Optionally, the storage device 22 provided in the present application is used to store at least 15 m of cushion rubber to meet the requirements of intermittent production of the molding machine.

[0039] Taking into account the symmetrical structure of the tire, a cutting device 24 is provided to cut the cushion rubber into two symmetrical cushion rubber strips. The cutting device 24 provided in the present application has an automatic deviation correction function so that the cutting device 24 cuts the cushion rubber along the central symmetry axis in the length direction of the cushion rubber to ensure that the widths of the two cushion rubber strips are the same.

[0040] In addition, the cutting device 24 provided in the present application also has the function of cutting the cushion rubber. The operator can control the cutting length of the cushion rubber by controlling the cutting device 24 for use in the molding process of the molding machine 10.
