Technical Field

[0001] The invention relates to the technical field of rubber machinery, in particular to an injection-type rubber pad laminating machine. Background Art

[0002] At present, the inner tube valve fitting mode is to pre-shape and pre-vulcanize the rubber pad first, the rubber pad is bonded to the copper tube, and then pre-vulcanized, and then the valve is brushed with glue to enhance the bonding strength.

DETAILED DESCRIPTION

[0022] The preferred embodiments of the present invention are further described below in conjunction with the accompanying drawings:

[0023] like Figure 1 and Figure 2 As shown, an injection type rubber pad laminating machine includes a frame 1 and a unit housing 2 correspondingly arranged on one side of the frame 1, an inner tube punching mechanism 3 is correspondingly arranged on the frame 1, the inner tube punching mechanism 3 is matched with a multi-station laminating mechanism 4, a plurality of valve molds 5 are correspondingly arranged on the multi-station laminating mechanism 4, the valve mold 5 is matched with an injection type extruder 6, and a screening mechanism 7 is correspondingly arranged on the side of the valve mold 5, the screening mechanism 7 is matched with the valve mold 5. The present invention has a simple structure, a relatively simple process, and a low defective rate of laminating, which saves costs, reduces equipment, and improves product quality.

[0024] like Figure 3 and Figure 4 As shown, the screening mechanism 7 is correspondingly arranged in the unit housing 2, and the screening mechanism 7 includes a vibration plate 71, and the vibration plate 71 is correspondingly connected to the guide rail 72, and the guide rail 72 is correspondingly connected to the transmission mechanism 73, and the transmission mechanism 73 matches the valve mold 5. The present invention uses the screening mechanism 7 to sequentially place the valve copper tubes into the transmission mechanism 73, and then place them one by one into the valve mold 5, thereby improving the overall automation and reducing labor costs.

[0025] like Figure 3As shown, the valve mold 5 includes a downward pressure cylinder 51, and the downward pressure cylinder 51 is correspondingly connected to the multi-station laminating mechanism 4. A laminating mold 52 is correspondingly provided on the side of the downward pressure cylinder 51. The laminating mold 52 receives the rubber injected by the injection extruder 6 and forms a rubber pad shape inside the mold. A nozzle cylinder 53 is correspondingly provided below the laminating mold 52, and the laminating mold 52 matches the injection extruder 6. In the present invention, the valve mold 5 mainly puts the valve copper tube into the laminating mold 52, and controls the movement of the laminating mold 52 and the injection extruder 6 through the movement of the downward pressure cylinder 51 and the nozzle cylinder 53, so as to realize the injection molding of the valve copper tube, and finally form a valve core with a rubber pad shape at the bottom and tightly connected with the valve copper tube.

[0026] The injection extruder 6 is correspondingly arranged above the multi-station laminating mechanism 4, and the injection extruder 6 includes a body 62, and a glue inlet 61 is correspondingly arranged on the side of the body 62 for adding rubber raw materials. A glue injection port 63 is correspondingly arranged at the bottom of the body 62, and the glue injection port 63 is correspondingly arranged just above the laminating mold 52. The glue injection port 63 can directly contact the laminating mold 52, and is used for injecting rubber, which is convenient for entering the laminating mold 52.

[0027] The multi-station laminating mechanism 4 includes a fixed column 42, one end of which is connected to the frame 1, and the other end of which is connected to the annular track 41. A plurality of downward pressure cylinders 51 are provided on the annular track 41, and the annular track 41 is electrically connected to the motor. An inner tube punching mechanism 3 is provided below the annular track 41. The multi-station laminating mechanism 4 of the present invention is provided with a plurality of valve molds 5 on the annular track 41. Through the rotation of the annular track 41, one of the valve molds 5 is rotated to the top of the inner tube punching position. Through the coordinated movement of the downward pressure cylinder 51 and the nozzle cylinder 53, the valve core that has been injected with rubber is directly attached to the inner tube, thereby completing the laminating process of the valve core to the inner tube surface.

[0028] like Figure 1 As shown, the inner tube punching mechanism 3 includes a conveying belt 31, and a puncher 32 is correspondingly arranged in the middle of the conveying belt 31, and the puncher 32 is correspondingly arranged at the front end below the circular track 41. The conveying belt 31 is correspondingly connected to the frame 1, and a rotating shaft 8 is correspondingly arranged at both ends of the frame 1. The conveying belt 31 matches the rotating shaft 8, and the rotating shaft 8 is correspondingly electrically connected to the belt motor 33. The present invention adjusts the speed of the conveying belt 31 so that the inner tube on the conveying belt 31 corresponds to the valve mold 5 on the circular track 41 in sequence, so that the valve core that has been injected with rubber material is directly attached to the surface of the inner tube.

[0029] In the specific implementation process, the valve copper tube is placed in the vibration plate 71 of the screening mechanism 7, and the vibration plate 71 is operated to send the valve into the fitting mold 52 of the valve mold 5 through the guide rail 72 and the conveying mechanism 73. Driven by the annular track 41, the valve mold 5 with the valve copper tube is conveyed to the bottom of the injection extruder 6, the downward pressure cylinder 51 rises, and the glue inlet of the fitting mold 52 is pressed against the glue extrusion port of the injection extruder 6, and the injection extruder 6 starts to squeeze and heat. The injection extruder 6 squeezes the rubber into the fitting mold 52, and the rubber forms a valve core during the heating process. The downward pressure cylinder 51 descends, and the valve mold 5 is separated from the injection extruder 6. Start the annular track 41 and rotate the valve mold 5 downward under the drive of the annular track 41 so that the outlet of the fitting mold 52 is aligned with the punched hole of the inner tube, and the downward pressure cylinder 51 descends to fit the valve core to the punched hole of the inner tube. After it is in place, the downward pressure cylinder 51 rises and the push-up cylinder 53 pushes out the valve core, and the valve core is installed on the inner tube to complete the whole process.

[0030] The worker places the inner tube on the conveyor belt 31, starts the belt motor 33 to transfer the inner tube along the running direction of the belt, and when the inner tube is transferred to the punching machine 32, the punching machine 32 moves downward to punch holes in the inner tube. After the punching is completed, the inner tube continues to move to the bottom of the annular track 41. When the punched part of the inner tube is aligned with the fitting mold 52, the valve mold 5 pushes out the valve core and installs it on the inner tube, completing the fitting process, and then proceeding to the next cycle process.

[0031] The injection-type rubber pad laminating machine of the present invention eliminates the valve mouth rubber pad pre-vulcanization process, the valve mouth grinding process, the valve mouth curtain process, and the manual valve mouth laminating process, and adopts a full-automatic valve mouth laminating process, thereby reducing the use of equipment and personnel, reducing production costs, and eliminating gasoline components, thereby ensuring that the site is more environmentally friendly and safer.

[0032] The specific structure, principle, and working process of how the valve nozzle mold and the injection extruder of the present invention are connected are well-known technologies and will not be described in detail here.

[0033] Although the technical solutions of the present invention have been described and listed in detail, it should be understood that it is obvious to those skilled in the art to make modifications to the above embodiments or adopt equivalent alternatives. These modifications or improvements made without departing from the spirit of the present invention are within the scope of protection required by the present invention.
