Description

Technical Field

[0001] The utility model relates to the technical field of tire production auxiliary equipment, in particular to a tire extrusion linkage line floating roller device with an automatic lifting function. Background Art

[0002] A tire is a combination of multiple semi-finished parts. After each process is completed, the semi-finished parts are transported to the molding and bonding process. Therefore, the stability of the size of each semi-finished product directly affects the quality of the tire. The tread and sidewall of the semi-finished products used are frameless materials. When they are transported on the linkage line, there are extremely high requirements for the speed matching between the various sections of the linkage line.

[0003] In order to ensure the speed matching between the sections of the extrusion linkage line and prevent the tread and sidewall from being stretched due to speed mismatch during transportation, resulting in unqualified dimensions, at this stage, floating roller angle positioners are installed between the sections to perform real-time detection of the tension of the components on the linkage line, thereby achieving real-time adjustment of the speed between the sections.

[0004] The extrusion production method is to produce multiple specifications alternately. Although this method solves the speed matching problem between the sections of the linkage line, due to the heavy weight of the floating roller itself, when the specification is alternately stopped, the floating roller exerts too much pressure on the components on the linkage line, causing local stretching of the components, resulting in unqualified dimensions, which also affects the stability of tire quality.

DETAILED DESCRIPTION

[0016] The utility model is further described below with reference to the accompanying drawings and embodiments. Embodiment 1

[0017] Reference Figure 1-2 As shown, a tire pressing line floating roller 4 device with automatic lifting function includes a floating roller 4 component located between two sections of conveyor belts and a rubber detection component for detecting the state of the linkage line. The rubber detection component is located on the conveyor belt in front of the floating roller 4 component.

[0018] The floating roller 4 assembly includes a first rocker arm shaft 1, a first rocker arm 3, a floating roller 4, an expander 6, a connecting rod 5 and a pushing block 7. The first rocker arm shaft 1 is horizontally arranged, and both ends thereof are mounted on the frame through a bearing seat 2; the two first rocker arms 3 are arranged side by side, and the upper ends of both are fixed on the first rocker arm shaft 1; the floating roller 4 is installed between the lower ends of the two first rocker arms 3, and the connecting rod 5 is vertically arranged on the first rocker arm shaft 1, one end of which is hinged to the first rocker arm shaft 1, and the other end is hinged to the output end of the expander 6; the main body of the expander 6 is hinged to the frame on the front side of the first rocker arm shaft 1, and one end of the pushing block 7 is fixed to the first rocker arm shaft 1, and the other end is located on the rear side of the connecting rod 5.

[0019] The rubber detection assembly includes a second swing rod shaft 9, a second swing rod 10, a rubber detection roller 11 and a rubber detection photoelectric device 12. A pair of supports 8 are symmetrically provided on both sides of the conveyor belt on the front side of the floating roller 4 assembly. The second swing rod shaft 9 is horizontally arranged, and its two ends are rotatably mounted on a support 8 respectively; the two second swing rods 10 are arranged side by side, and the upper ends of both are fixed on the second swing rod shaft 9; the rubber detection roller 11 is installed between the lower ends of the two second swing rods 10, and the rubber detection photoelectric device 12 is arranged parallel to the second swing rod 10, which is installed on the inner side of a second swing rod 10 and is opposite to the central axis of the rubber detection roller 11; a semi-ring stopper 13 corresponding to the rubber detection photoelectric device 12 is provided on the outer wall of one end of the rubber detection roller 11.

[0020] It also includes a controller, and the telescoping device 6 and the glue detection photoelectric device 12 are both electrically connected to the controller.

[0021] In more detail, the retractor 6 of this embodiment is a cylinder.

[0022] The rubber detection roller 11 contacts the rubber component 14 on the conveyor belt. During normal production, the rubber component 14 on the conveyor belt drives the rubber detection roller 11 to rotate, and the rubber detection photoelectric 12 monitors the rotation of the rubber detection roller 11 through the semi-ring block 13, and transmits the linkage line operation signal to the controller. The controller controls the cylinder rod to retract, driving the connecting rod 5 to rotate forward, releasing its limit on the push block 7, so that the floating roller 4 can fall normally. The floating roller 4 contacts the rubber component 14 normally, so as to detect the tension of the rubber component 14 on the linkage line in real time, and realize the real-time adjustment of the speed between each section.

[0023] When the specification is alternately stopped, the rubber detection roller 11 stops rotating, and the rubber detection photoelectric 12 receives the stop signal of the linkage line and transmits the signal to the controller. The controller controls the cylinder rod to extend, and pushes the push block 7 backward through the connecting rod 5 to lift the floating roller 4, thereby solving the problem that the floating roller 4 exerts too much pressure on the rubber component 14 on the linkage line during shutdown, causing the rubber component 14 to be partially stretched.

[0024] The device has a simple structure and strong practicality. It can detect the state of the linkage line through the glue detection component and adjust the floating roller 4 component through the controller, thereby solving the problem that the floating roller 4 applies excessive pressure to the glue component 14 on the linkage line during shutdown, causing local stretching of the glue component 14.

[0025] The present invention is not limited to the above-mentioned implementation modes. Within the knowledge scope of those skilled in the art, various changes can be made without departing from the purpose of the present invention. The changed contents still belong to the protection scope of the present invention.
