The outer edge of the orifices is flush with the inner edge of the guiding slope, and the inner edge of the orifices is flush with the edge of the dispensing column. The edge of the dispensing column is flush with the edge of the orifices. This utility model has a simple structure, effectively utilizes the extruder's power, reduces glue blockage, increases the number of orifices, and improves work efficiency.
[0004] However, the aforementioned patent does not allow for adjustment of the tire pad thickness during use. This results in companies having to frequently change the extrusion die plate when producing tire pads with different thickness requirements, increasing production costs and production cycles. Furthermore, the inability to flexibly adjust the thickness also limits the company's ability to respond to diverse market demands and reduces its competitiveness in the market. Utility Model Content
[0005] The purpose of this utility model is to overcome the shortcomings of the above-mentioned technology and provide a tire pad with a press-out outlet plate.
[0006] Therefore, this utility model provides a tire pad tape pressing die plate, which can adjust the thickness of the tire pad tape to adapt to different production needs.
[0007] Preferably, it includes a rear cover, a front cover is fixedly installed at the front end of the rear cover, a discharge chute is located between the rear cover and the front cover, a connector is fixedly connected to the rear end of the rear cover, a conical block is fixedly connected inside the connector, and an adjustment component is installed between the rear cover and the front cover.
[0008] The adjusting assembly includes a screw, a mounting hole, and a nut. The screw is fixedly connected to the front end of the conical block. The front cover has a mounting hole inside, through which it is fitted onto the screw. The nut is threaded onto the outer wall of the screw and is located at the front end of the front cover.
[0009] Preferably, the adjustment assembly further includes a slide rod, a sliding hole, and a spring. There are multiple slide rods arranged in a ring at the front end of the rear cover. There are multiple sliding holes arranged in a ring inside the front cover. The front cover is sleeved on the slide rod through the sliding holes. The spring is sleeved on the outer wall of the slide rod and is located between the rear cover and the conical block.
[0010] Preferably, the inner wall of the connector is fixedly connected to a connecting block, and multiple connecting blocks are distributed in a ring on the inner wall of the connector, with the conical block fixedly connected to the inner wall of the multiple connecting blocks.
[0011] Preferably, the outer wall of the connector is threaded, and the connector is fixedly threaded to the discharge end of the extruder.
[0012] Preferably, the pointed end of the conical block faces the feed end of the connector.
[0013] Preferably, the connector is connected to the discharge trough.
[0014] This utility model provides a tire pad with a press-out exit plate, which has the following beneficial effects:
[0015] By incorporating an adjustment mechanism, during operation, rotating the nut converts its rotation into linear movement along the screw due to the threaded connection between the nut and the screw. This movement, in turn, propels the front cover to slide along the screw via a spring. Simultaneously, the sliding rod and sliding hole work together to precisely guide the movement of the front cover, ensuring smooth movement and preventing deviation. The movement of the front cover alters the distance between the rear and front covers, thus controlling the opening size of the discharge chute. When the discharge chute opening widens, the extruded tire pad tape becomes thicker; conversely, when the opening narrows, the tire pad tape becomes thinner. This allows companies to quickly and precisely adjust the tire pad tape thickness according to different production needs, significantly improving production flexibility, meeting the diverse market demands for tire pad tapes of varying thicknesses, and enhancing the company's competitiveness in the market.
