Description

Technical Field

[0001] The utility model belongs to the technical field of conveyor belts, and in particular relates to a base glue extrusion device. Background Art

[0002] V-belt is a transmission belt with a V-shaped cross-section, usually used to transmit power and drive rotating mechanical equipment. V-belt is usually made of rubber and fiber materials, has good wear resistance and elasticity, and is suitable for various industrial and mechanical transmission applications.

[0003] During the production process of V-belts, it is necessary to adhere a base glue to the belt body. The base glue can strengthen the overall structure of the V-belt, improve its tensile strength and wear resistance, and enable the V-belt to withstand greater tension and torque during the transmission process.

[0004] In the actual production process, the base glue colloid needs to be extruded and formed. The existing base glue extrusion head is a conical extrusion head. Due to the geometric characteristics of the cone angle and curvature, the pressure distribution of the colloid in the conical extrusion head will be uneven. The colloid produces a pressure difference at different positions in the cone, which makes the base glue material unevenly extruded, and then leads to uneven shape or surface molding of the base glue, which will cause quality problems of the V-belt, such as cracks, breakage, etc., and reduce product quality. Utility Model Content

[0005] The present application proposes a base rubber extrusion device for improving the uniformity of base rubber material extrusion molding, thereby improving the production quality of V-belts.

[0012] In one embodiment of the present application, a mounting plate is connected to the bottom end of the telescopic rod.

[0013] In one embodiment of the present application, a cooling fan is provided on the side of the glue outlet hole.

[0014] To sum up, the technical solution proposed in the present application includes the following beneficial technical effects: the colloid enters the injection cavity through the injection tube, and the colloid flows through the injection cavity into the runner cavity. Compared with the conical curved cavity, the runner cavity has a continuous and uniform shape, which can make the extruded colloid more uniformly stressed when flowing in the runner cavity, which is beneficial to improving the uniformity of the colloid flowing out of the glue outlet, improving the uniformity of the shape and size accuracy of the base glue after the extruded colloid is solidified, and improving the molding quality of the base glue.

[0033] In the above embodiment, a flow channel cavity 14 and a glue injection cavity 15 are formed inside the upper head body 11 and the lower head body 12. A glue outlet 141 is provided at one end of the flow channel cavity 14, and a die plate 3 is installed at the glue outlet 141. The other end of the glue injection cavity 15 is connected with the glue injection tube 2, wherein the glue injection tube 2 is used to inject pressurized hot melt colloid into the glue injection cavity 15. After the colloid enters the glue injection cavity 15, the other end of the flow channel cavity 14 is connected with one end of the glue injection cavity 15, and the colloid flows through the glue injection cavity 15 into the flow channel cavity 14. Compared with the conical curved cavity, the flow channel cavity 14 has a continuous and uniform shape, which can make the extruded colloid more uniformly stressed when flowing in the flow channel cavity 14, which is beneficial to improve the uniformity of the colloid flowing out of the glue outlet 141, thereby improving the uniformity of the shape of the base glue after the extruded colloid is solidified and formed, thereby improving the molding quality of the base glue. In addition, a glue outlet 141 is provided at one end of the flow channel cavity 14, and a die plate 3 is installed at the glue outlet 141, and a plurality of glue outlet holes 31 are evenly arranged on the die plate 3.

[0035] In the above embodiment, if Figure 2For example, the slider 41 can move up and down along the direction in which the slide groove 4 is set, and an adjusting bolt 43 is provided in the threaded hole 42. For example, the adjusting bolt 43 in the threaded hole 42 is rotated to move up, and one end of the adjusting bolt 43 is rotatably connected to the top of the slider 41 through a rotating shaft. For example, the rotating shaft is nested in the slider 41, and one end of the adjusting bolt 43 is fixedly connected to the rotating shaft. The rotation of one end of the adjusting bolt 43 can drive the rotating shaft to rotate in the slider 41, and the up and down movement of one end of the adjusting bolt 43 can drive the rotating shaft to move up and down, thereby driving the slider 41 nested with the rotating shaft to move up and down. The upward movement of the bolt 43 will pull the slider 41 up along the slide groove 4. Similarly, the downward movement of the adjustment bolt 43 will drive the slider 41 to move downward, so that the slider 41 extends into the flow channel cavity 14 to change the flow cross-section of the colloid in the flow channel cavity 14. The flow rate of the colloid is adjusted by changing the flow cross-section of the colloid. By adjusting the flow rate of the glue outlet 141, the flow speed and flow rate of the extruded colloid in the molding process can be controlled. Adjusting the flow rate of the glue outlet 141 according to actual conditions during production helps to optimize product quality, ensure that the product meets design requirements, and is beneficial to improving the molding quality of the base glue.
