Description

Technical Field

[0001] The invention relates to the technical field of industrial machinery and equipment for manufacturing rubber products, and in particular to a hydraulically locked frame material rubber coating machine head. Background Art

[0002] In recent years, with the rapid development of rubber product manufacturing technology, the application of extruders has become more and more extensive. Due to the wide variety of product specifications, the extruder needs to frequently change the die tooling during the extrusion process. Therefore, the product extruder head, whether it is a composite extruder head or a single screw extruder head, is usually designed to be openable, using a convenient, fast, simple and reliable hydraulic locking mechanism to achieve the purpose of frequent opening and closing of the head and effective sealing.

[0003] Due to the needs of product structure technology, some skeleton materials, such as steel wire, nylon, etc. are often used in products to achieve the purpose of strengthening the skeleton. This requires adding a layer of rubber to the surface of these skeleton materials in advance so that the rubber and the skeleton materials can be integrated when the product is formed. There are currently three commonly used rubber coating processes: cold calendering process, hot calendering process and extrusion coating process. Among them, the extrusion coating process has been widely used in the field of rubber products and tire manufacturing due to its small batch, multiple specifications, flexibility and convenience.

[0004] However, due to the particularity of the process structure, the glue coating machine head currently used for the skeleton material coating generally adopts a mechanical locking method. Although this structure of the machine head can meet the needs of the skeleton material coating, it still has the disadvantages of being cumbersome to operate, taking a long time, having low locking reliability, and having high labor intensity.

[0032] Please refer to Figure 1 to Figure 7 The embodiment of the present invention provides a hydraulic locking type frame material glue coating head, which is characterized by comprising a support frame 1, a glue coating head fixing mechanism, a glue coating head movable mechanism, a locking arm 14 and a driving mechanism; wherein,

[0033] The glue coating head fixing mechanism is arranged on the top surface of the support frame 1, including an L-shaped lower head body 2 fixedly arranged on the top surface of the support frame 1, a notch 3 is arranged at the bottom of the lower head body 2, an oblique hook body 4 is fixedly arranged at the bottom of the lower head body 2 below the notch 3, and a flared groove 5 is arranged on the top surface of the oblique hook body 4; a lower groove 6 is arranged on the top surface of the lower head body 2 near the notch 3, and a lower flow channel plate 7 is arranged inside the lower groove 6;

[0044] In a preferred embodiment, an upper head hook body 20 is fixedly provided on the top of the upper head body 8, pins 21 are symmetrically fixedly provided on both sides of the upper head hook body 20, and a baffle 22 is fixedly provided on one end of the pin 21 away from the upper head hook body 20.

[0045] In a preferred embodiment, the driving mechanism includes a bracket body 23 fixedly arranged on the top of the lower head body 2, and the bracket body 23 is hingedly connected to the end of the upper head hook body 20 away from the upper head body 8; a first cylinder 24 is arranged on the bracket body 23, and the end of the piston rod of the first cylinder 24 away from the first cylinder 24 is hingedly connected to the upper head hook body 20; L-shaped safety hook rods 25 are symmetrically arranged on both sides of the bracket body 23, and the installation hook rods 25 are rotatably arranged on both sides of the bracket body 23 corresponding to the pin shaft 21, and an axle rod 26 is arranged between the two safety hook rods 25; a second cylinder 27 is arranged on the side of the bracket body 23 away from the upper head hook body 20, and the end of the piston rod of the second cylinder 27 away from the second cylinder 27 is rotatably arranged on the axle rod 26, and the bottom end of the second cylinder 27 is rotatably arranged on the bracket body 23.

[0046] Due to the presence of the skeleton material, the space of the machine head locking device is limited. The core of the present invention is to divide the locking mechanism into two parts, which are distributed on both sides of the skeleton material so as not to affect the transportation of the skeleton material during operation; two locking arms 14 are installed on both sides of the lower machine head body 2 by screws, and a boss 16 is provided on the top of the locking arm 14. One side of the boss 16 is tightly attached to the upper machine head body 8 and is hooked by a hook 13 installed on the upper machine head body 8, so as to prevent the locking arm 14 from moving laterally during the locking process of the upper machine head body 8 and the lower machine head body 2.

[0047] Working principle of the present invention:

[0048] The piston rods of the first hydraulic cylinder 121 and the second hydraulic cylinder 171 are in a retracted state, and the upper machine head body can be freely opened or closed by the drive of the first cylinder 24. One end of the hook 13 is fixed on the upper machine head body 8, and the other end is hooked on the outer side of the boss 16 of the locking arm 14, so as to constrain the lateral spacing freedom between the upper machine head body 8 and the locking arm 14;

[0049] When locking the upper head body 8 and the lower head body 2, the piston rod of the second hydraulic cylinder 171 drives the second pressure plate 173 to extend to the top surface of the pad 19. Since there is an inclined surface between the pad 19 and the second pressure plate 173, under the action of the inclined surface force amplification principle, the force of the second hydraulic cylinder 171 in the normal direction on the pad 19 is greatly amplified. This amplified force is the force required to lock the movable mold of the head body (that is, the upper head body 8 and the lower head body 2); similarly, the piston rod of the first hydraulic cylinder 121 drives the first pressure plate 123 to extend into the internal setting of the notch 3, so that the second inclined surface and the first inclined surface 15 are squeezed against each other, and have a force to drive the lower head body 2 upward, and cooperate with the second locking assembly 17 to further lock the movable mold of the head body and improve the locking effect.
