Description

Technical Field

[0001] This utility model relates to the field of curtain forming machine technology, specifically a device for preventing curtain stretching in a forming machine. Background Technology

[0002] Cord forming machines are key equipment in the production of rubber tires and industrial cord fabrics. They are mainly used to bond cord fabrics (such as nylon, polyester, steel cord fabrics, etc.) into specific shapes and structures according to tire manufacturing process requirements. Industrial cord forming machines are core equipment in the rubber industry. They use servo motor drives and ball screw transmissions to ensure that the positioning accuracy of the cord fabric on the forming drum is ≤±0.1mm.

[0003] Regarding the above and existing related technologies: when the molding machine stops, the curtain fabric hangs in mid-air for a long time, and its own weight will continuously exert a downward pulling force. Without effective support and restraint, this situation can easily cause the curtain fabric to stretch and deform. The stretching of the curtain fabric may change its original physical properties, such as uneven changes in the thickness and density of the curtain fabric, which may lead to problems affecting the quality of subsequent products. Therefore, a device to prevent the curtain fabric from stretching in a molding machine is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The forming machine anti-stretching device of this utility model includes a bracket, a tray and a fabric. The tray is located on one side of the bracket. Two bearing seats are fixedly connected to the side wall of the bracket. The inner surfaces of the two bearing seats are fixedly connected to the surface of the tray. The fabric is located on the upper surface of the tray. Pneumatic components are fixedly connected to the surfaces of the bracket and the tray. A manual valve is fixedly connected to the side wall of the bracket. The manual valve drives the pneumatic components to move. The pneumatic components drive the tray to move. The tray drives part of the bearing seat structure to rotate. The tray supports the bottom of the fabric. By setting the entire device, the fabric can be supported, preventing the fabric from being stretched and deformed due to its own weight over a long period of time.

[0006] Preferably, the bottom end of the bracket is provided with an adjustment device, which includes a pad located directly below the bracket. Two sleeve rods are fixedly connected to the upper surface of the pad, and threaded rods are threaded to the inner walls of the sleeve rods. A base is rotatably connected to the upper surface of the threaded rods, and the base is located at the bottom end of the bracket. The threaded rods drive the base to move its height. After the base moves to a suitable height, the bracket is placed on the base. The bracket can be supported by the pad, sleeve rods, threaded rods, and base.

[0007] Preferably, the inner walls of the bracket and the base are threaded with multiple positioning pins. After the bracket is placed on the upper surface of the base, the positioning pins are rotated to the inner walls of the bracket and the base, and the positioning pins can restrict the position of the bracket on the surface of the base.

[0008] Preferably, the surface of the pad has multiple adapter holes, and the inner wall of the adapter holes of the pad is provided with bolts. After the pad is placed in a suitable position, the bolts are rotated into the inner wall of the adapter holes and the mounting holes of the pad. The opening of the adapter holes can fix the position of the pad.

[0009] Preferably, a turntable is fixedly connected to the surface of the threaded rod, and a belt is engaged with the surfaces of the two turntables. When the threaded rod needs to be operated, the belt is pulled to make the two turntables rotate, and the turntables drive the threaded rod to rotate. By setting the belt and turntables, the rotation of the threaded rod can be easily driven.

[0010] Preferably, a fixing rod is fixedly connected to the surface of the two bases, and a plurality of support blocks are fixedly connected to the bottom end of the fixing rod. The belt is inserted into the inner surface of the support block. When the belt moves, the belt moves on the inner surface of the support block at the bottom end of the fixing rod, and the fixing rod and the support block can support the belt.

[0011] Preferably, the sleeve rod has a threaded hole on its surface, and the inner wall of the threaded hole of the sleeve rod is threadedly connected to the surface of the threaded rod. When the threaded rod rotates, the threaded rod rotates on the inner wall of the threaded hole of the sleeve rod. The opening of the threaded hole facilitates the rotation of the threaded rod.

[0012] The advantages of this utility model are:

[0013] 1. After the molding machine stops, the manual valve on the operating bracket drives the pneumatic component to start, which in turn drives the tray to move. The movement of the tray causes a part of the bearing seat structure to rotate. When the tray moves, it fits against the bottom of the fabric. After the tray lifts the fabric, the manual valve stops. By setting the tray, the fabric can be supported in time, preventing the fabric from stretching and deforming due to its own weight over a long period of time, thus ensuring the quality of the fabric. This reduces subsequent production failures caused by fabric stretching and other problems, and improves the stability and reliability of the entire molding machine production process. The design of the manual valve makes the operation simple and intuitive, eliminating the need for a complex automated control system and reducing the complexity of the equipment and maintenance costs.

[0014] 2. When the bracket is needed, the pad is placed in a suitable position, and the bolt is rotated into the inner wall of the adapter hole and the mounting hole of the pad. Then, the belt is pulled to make the turntable rotate, and the turntable drives the threaded rod to rotate. The threaded rod rotates in the inner wall of the sleeve rod and the bottom end of the base. The threaded rod will drive the base to move. When the belt moves, it will move in the inner surface of the support block at the bottom end of the fixed rod. After the base moves to a suitable height, the belt is stopped. Then, the bracket is placed on the upper surface of the base, and the positioning pin is rotated into the inner wall of the bracket and the base. By setting the entire device, the bracket can be supported, and the height of the bracket can be easily adjusted to adapt to different terrains. Attached Figure Description
