Description

Technical Field

[0001] The utility model relates to the technical field of rubber compound extrusion winding machines, in particular to a rotating head of an extrusion winding machine. Background Art

[0002] In the rubber extrusion winding equipment, the extruder completes the plasticization of the rubber compound, produces a regularly shaped rubber strip through the die head, and then winds it onto the produced parts as required;

[0003] Extrusion winding is divided into flat winding and arc winding according to the different winding parts.

[0004] The flat winding process is to apply the rubber strip spirally to the winding component by reciprocating the extruder in a direction parallel to the rotation axis of the winding component (or the extruder is stationary and the winding component reciprocates along the rotation axis direction), such as rubber roller winding.

[0005] Arc winding means that the adhesive surface of the winding component has a certain curvature, and the film needs to be applied perpendicular to the tangent of the arc surface. In addition to reciprocating operation, the extruder and winding components also need to have a certain rotation function at the glue outlet, which is technically difficult. Therefore, the current arc winding separates the production equipment and designs a separate set of winding machines. The winding head has reciprocating and rotating functions, and the extruder is fixed and only used for the extrusion of plasticized rubber. Changing the production process can solve the problem of arc winding, but it also has some disadvantages.

[0006] The production line occupies a large area and has high cost investment. The extrusion winding machine is divided into an extruder, a winding machine and an intermediate rubber material conveying system;

[0007] The production operation process is cumbersome. For the first time, the rubber strip needs to be manually pulled from the extruder along the production line to the winding head.

[0008] The quality of the rubber strip is reduced, and the rubber material will cause a certain amount of stretching or shrinking in the middle link;

[0009] Production needs to be started and stopped frequently according to the beat. The rubber material at the extruder die is prone to breakage or large changes in shape due to the alternating hot and cold environment, resulting in low efficiency and reduced product quality. Summary of the Invention

[0010] The purpose of the utility model is mainly to address the problems of large floor space, high cost, and bottlenecks in production efficiency and product quality improvement in the current arc extrusion winding process, and to provide a rotating head of an extrusion winding machine that realizes extrusion application within the rubber material.

[0011] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rotating head of an extrusion winding machine, comprising an elbow body, a sleeve body being provided on the upper part of the elbow body, a rotating shaft being rotatably connected to the sleeve body, a die plate being fixedly connected to one side of the rotating shaft, and a pressing part being installed, the pressing part being located above the die plate, the pressing part comprising a pressure roller, a pressure roller fixing frame, and a guide rod sliding frame, the pressure roller being rotatably connected to the pressure roller fixing frame, a guide long rod and a compression spring being provided between the pressure roller fixing frame and the guide rod sliding frame, and the guide rod sliding frame being fixed to one side of the rotating shaft.

[0012] Preferably, a flange is provided on the fixed sleeve at the bottom end of the sleeve body, and fixing ports distributed in a circumferential array are provided on the upper part of the flange. A threaded groove is provided at the corresponding position of the elbow body relative to each fixing port, and a turntable is provided on the outer side of the sleeve body. The bottom of the turntable is rotatably connected to an inner gear ring and spur gears distributed in a circumferential array, and a threaded rod threadedly connected to the threaded groove is provided on one side of the spur gear, and the spur gear is meshed with the inner gear ring.

[0013] Preferably, a fixing ring is provided on the outer fixing sleeve of the sleeve body, and the fixing ring is located above the turntable. A spring is provided on the outer sliding sleeve of the sleeve body, and the spring is located between the fixing ring and the turntable.

[0014] Preferably, a through hexagonal groove is provided on the upper portion of the spur gear, and a nut that matches the cavity of the hexagonal groove is fixedly connected to the top end of the threaded rod, and the nut has a hexagonal structure.

[0015] Preferably, a placement groove distributed in a circumferential array is opened on the upper part of the turntable, the spur gear is rotatably placed in the placement groove cavity, a through placement opening is formed on the bottom wall inside the placement groove, and the bottom of the spur gear is fixedly connected to a bottom tube adapted to the placement opening.

[0016] Preferably, a baffle is rotatably connected to the upper portion of the turntable, and a through-type opening is opened at a corresponding position of the baffle relative to each placement slot.

[0017] Preferably, a closed chamber is formed between the outer wall and the inner wall of the elbow body, and one side of the elbow body is fixedly connected to a temperature control pipeline.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. This application introduces an elbow assembly to change the direction of the rubber (the horizontal extrusion pressure of the rubber in the extruder is high, and the rotating shaft is very easy to get stuck), and then designs a sharp taper design on the rotating shaft to avoid dead rubber. A rubber chamber is designed on the rotating shaft to make the rubber flow smoothly, and then the rubber is extruded through the die plate after the direction of the rubber is changed, and applied to the tire body or the roller; the external application is changed to the internal application to focus on solving the problem of the rubber outlet swing, realizing the internal extrusion and application of the rubber, and improving the winding quality.

[0020] 2. This application sets up spur gears and internal gear rings. It only needs to align each threaded rod with the fixing port on the corresponding flange and the thread groove on the elbow body, and then press down and rotate the internal gear ring. The internal gear ring will drive each threaded rod through each spur gear and simultaneously thread it into its corresponding thread groove. This can effectively improve the convenience of disassembly, assembly and maintenance of the rotating head of the extrusion winding machine.

[0021] 3. This application sets a baffle to facilitate the disassembly and assembly of bolts, thereby improving the assembly applicability of the rotating head of the extrusion wrapping machine. At the same time, the device replaces the force of pressing down the turntable through the elastic setting of the spring, thereby further improving the convenience of assembling or disassembling the rotating head of the extrusion wrapping machine.
