Description

Technical Field

[0001] The utility model belongs to the technical field of machine barrels, in particular to a machine barrel with an exhaust port. Background Art

[0002] Based on the direction of the material flow in the die and the angle between the centerline of the screw, the die head of the extruder can be divided into right-angle die head and bevel die head. The screw extruder relies on the pressure and shear force generated by the rotation of the screw to fully plasticize and evenly mix the material and form it through the die. [2] Plastic extruders can be basically classified into twin-screw extruders, single-screw extruders, and the rare multi-screw extruders and screwless extruders. The screw extruder barrel is an important component of the extruder, used to contain and transport materials. The material is pushed forward by the rotation of the screw and plasticized, mixed, etc. The screw extruder barrel is usually divided into two types: single-screw extruder barrel and twin-screw extruder barrel.

[0003] For example, a double-exhaust screw barrel with publication number CN 207028140 U includes a barrel with flange threads at both ends and a primary exhaust port and a secondary exhaust port in the middle. This double-exhaust screw barrel has excellent exhaust performance, eliminating the need for dryers for materials with sufficient moisture, allowing them to be directly fed into the production process, thereby enhancing plasticizing capacity. Furthermore, this double-exhaust screw barrel improves production efficiency and significantly reduces costs.

[0004] This machine barrel is used to dry the material by opening an exhaust port on the barrel. This structure is natural exhaust, but in some processes, the material needs to be vacuum-exhausted, or no exhaust is required, resulting in a low applicability. In order to solve the above problem, a machine barrel with an exhaust port is proposed. Utility Model Content

[0005] The purpose of the present invention is to provide a barrel body with an exhaust port in order to solve the above problems, comprising:

[0006] The cylinder has two bosses welded on one side of its upper surface, a first flange welded on the top of the boss, an exhaust groove opened in the center of the boss, and an exhaust pipe integrally provided on one side of the boss;

[0007] The sealing mechanism is fixedly mounted on the top of the first flange by means of bolts.

[0008] Through the above technical solution, the cylinder is naturally exhausted through the exhaust groove in the center of the boss. When vacuum exhaust is required, the exhaust groove is sealed by a sealing mechanism. When vacuum exhaust is not required, the exhaust groove is sealed by a sealing mechanism, and then the exhaust pipe is connected to the vacuum machine to achieve vacuum exhaust. This cylinder has a variety of exhaust mechanisms suitable for various process environments.

[0009] In a preferred embodiment, a fixing frame is fixedly mounted on the upper surface of the sealing mechanism, a cylinder is fixedly mounted on the top of the fixing frame, and a sealing plate is fixedly mounted on the end of the output shaft of the cylinder.

[0010] With the above technical solution, when the cylinder needs to be sealed, the cylinder is extended to drive the sealing plate to move downward, so that the sealing plate seals the exhaust groove, thereby putting the cylinder in a sealed state.

[0011] In a preferred embodiment, the sealing plate and the exhaust groove are of the same size and shape.

[0012] In a preferred embodiment, guide rods are welded to the upper surfaces of both left and right sides of the sealing plate, and the guide rods are slidably connected to the upper end of the fixing frame.

[0013] With the above technical solution, the guide rod is provided so that the sealing plate always moves along a straight line during the movement process, thereby improving the sealing performance of the equipment.

[0014] In a preferred embodiment, second flanges are welded to both the left and right sides of the cylinder.

[0015] Through the above technical solution, the cylinder is connected to other equipment through the second flange.

[0016] In a preferred embodiment, an embedded block is fixedly mounted on the inner wall of the cylinder by bolts.

[0017] With the above technical solution, when the interior of the cylinder is damaged after long-term use, the embedded block can be removed from the interior, thereby facilitating maintenance of the cylinder.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows: the present invention provides a barrel body with an exhaust port.

[0019] The cylinder is naturally exhausted through the exhaust groove in the center of the boss. When vacuum exhaust is required, the exhaust groove is sealed by a sealing mechanism. When vacuum exhaust is not required, the exhaust groove is sealed by a sealing mechanism, and then the exhaust pipe is connected to the vacuum machine to achieve vacuum exhaust. This cylinder has a variety of exhaust mechanisms suitable for various process environments. BRIEF DESCRIPTION OF THE DRAWINGS
