Description

Technical Field

[0001] The invention relates to the technical field of extruders, in particular to a heat-insulating extruder for producing energy-saving extruded boards. Background Art

[0002] Plastic is a polymer compound that is polymerized by addition or condensation reaction with monomers as raw materials. It can be arbitrarily molded into various shapes and can finally keep the shape unchanged. Plastic has a medium deformation resistance, between fiber and rubber. It is composed of synthetic resin and additives such as fillers, plasticizers, stabilizers, lubricants, colorants, etc. Plastic, synthetic rubber and synthetic fibers form the three major synthetic materials that are indispensable in daily life. Specifically, plastic is a material that uses natural or synthetic resin as the main component, adds various additives, can be molded into a certain shape under certain temperature and pressure conditions, and keeps the shape unchanged at room temperature.

[0003] In the existing extruded board production technology, the traditional extruder is usually composed of simple basic units such as feeding, extrusion, and molding. The feeding link often simply relies on gravity or a simple feeding device to feed the raw materials into the barrel. This method is difficult to ensure the stability and continuity of the raw material supply, and it is easy to have insufficient raw material supply, which in turn affects the production efficiency. During the extrusion process, the barrel is mostly heated by a single heating element in a fixed position, which cannot achieve accurate control and uniform heating of the barrel temperature, resulting in uneven plasticization of the raw materials, uneven quality of the extruded board products, and problems such as loose internal structure and insufficient strength. Moreover, due to the serious heat loss, in order to maintain the temperature required for production, a large amount of additional energy has to be consumed, resulting in high production costs. In the conveying link of the extruded board after molding, the conveying device is simply designed, lacks effective linkage control, is out of touch with the front-end production link, and cannot be delivered to the subsequent process in time, resulting in an unsmooth production process, further reducing the overall production efficiency. Therefore, a heat-insulating extruder for energy-saving extruded board production is needed. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a thermal insulation extruder for the production of energy-saving extruded boards, which solves the problems of unstable feeding link, rising production costs due to the inability to achieve precise control and uniform heating, and the disconnection between the transportation link and the front-end production link, which makes it impossible to transport the extruded boards to subsequent processes in time, resulting in an unsmooth production process.

[0008] Preferably, the elastic component includes a spring arranged at the front end of the slide rod, the front end of the slide rod is fixedly connected with a circular limit plate, and the circular limit plate is arranged at the front side of the slide block.

[0009] Preferably, the linkage assembly three includes a sprocket fixedly connected to the rear end of the transmission rod and the rear end of the screw rod, and the two sprockets are connected by a chain.

[0010] Preferably, the linkage assembly 1 includes a worm fixedly connected to the front end of the transmission rod, and one end of the rear conveying roller is fixedly connected to a turbine, and the worm and the turbine are meshingly connected.

[0011] Preferably, the gear set includes a driving gear fixedly connected to the middle end of the crushing chamber, and a driven gear is rotatably connected to the top side of the crushing chamber, and the driven gear and the driving gear are meshingly connected.

[0013] Preferably, a motor 1 is installed on the top side of the crushing chamber through a fixing frame, and the driving end of the motor 1 is fixedly connected to the top side of the driving gear.

[0014] Preferably, an arc-shaped plate 1 is fixedly connected to the top side of the rear end of the barrel, and an arc-shaped plate 2 is fixedly connected to the top side of the baffle.

[0015] Working principle: Before the production of extruded board, the raw material is first transported to the inside of the crushing chamber through the feed pipe, and then the driving gear is controlled to rotate by starting motor 1. Through the meshing connection between the driving gear and the driven gear, the crushing shaft on the bottom side can be driven to rotate by a single driving driving gear, and the remaining crushing shafts can be driven to rotate by the driven gear. At the same time, due to the meshing connection between the driving gear and the driven gear, the crushing shaft connected to the bottom side of the driving gear and the remaining crushing shafts have different rotation directions, so the raw materials inside the crushing chamber can be effectively crushed. The crushed raw materials continue to be stored in the crushing chamber. Then, by starting the barrel heating and starting motor 2 to drive the transmission rod to rotate, the rotating transmission rod can synchronously drive the conveying roller to rotate through the meshing connection between the worm and the turbine at its front end, so as to facilitate the transportation of the extruded board produced from the barrel later. The sprockets arranged at the rear end of the transmission rod and the rear end of the screw are linked by a chain, which can drive the screw to rotate inside the barrel. At this time, the rotating screw will drive the rotating disk at the rear end to rotate, and the rotating rotating disk will be driven by lever 2 to lever 1 The movement of the lever drives the baffle to swing on the outer wall of the rear end of the barrel. At this time, the baffle can be moved away from the bottom of the discharge pipe and the top side of the feed port. The crushed raw materials stored in the crushing chamber will flow to the inside of the discharge pipe through the guide cover. The raw materials in the discharge pipe will directly fall into the inside of the feed port and then fall into the inside of the barrel. The raw materials in the barrel are processed by the rotating screw and barrel. At the same time, when the baffle and the lever swing on the outer wall of the rear end of the barrel, the connecting shaft fixed on the top side of the lever will pull the traction rope to slide on the outer wall of the rotor. At this time, The traction rope pulls the sliding rod to move, and the sliding rod will slide on the inner wall of the limit block. At this time, the spring on the outer wall of the front end of the sliding rod is compressed, and at the same time, the sliding block and the annular heating module are pulled to move inside the insulation chamber through the circular limit plate. When the lever two no longer moves the lever one, the compressed spring will first reset and pull the front end sliding block and the annular heating module to move, and drive the remaining annular heating modules to move inside the insulation chamber, thereby realizing the continuous reciprocating motion of the annular heating module inside the insulation chamber, realizing the heating and insulation of the outer wall of the barrel, and achieving the effect of energy saving.

[0016] The present invention provides a heat-insulating extruder for producing energy-saving extruded boards. It has the following beneficial effects: 1. The present invention provides a plurality of crushing shafts in the crushing chamber, and realizes rotation in different directions through the meshing relationship between the driving gear and the driven gear. The rotation in opposite directions causes the raw materials to be sheared and squeezed in multiple directions in the crushing chamber, which can efficiently complete the crushing of the raw materials and make the crushed raw materials more uniform, providing a better raw material basis for subsequent extrusion processing and improving product quality.

[0017] 2. The present invention drives the transmission rod and the screw to rotate through the second motor, drives the rotating disk and the second lever to move, thereby controlling the opening and closing of the baffle and realizing the automatic feeding of the crushed raw materials. At the same time, the annular heating module realizes reciprocating motion in the insulation chamber through the linkage of the spring and the traction rope, heats and insulates the outer wall of the barrel, and improves production efficiency and continuity. The reciprocating motion of the annular heating module realizes uniform heating and insulation of the outer wall of the barrel, reduces heat loss, reduces energy consumption, and ensures the stability of the processing process.

[0018] 3. The present invention ensures the continuity of raw materials from crushing to processing through the coordinated work of the crushing chamber and the barrel, thereby improving production efficiency and equipment reliability. The coordinated work between the various components ensures the smoothness of the production process, reduces the waiting time in the intermediate links, and further improves the overall production efficiency.

When the transmission rod 14 rotates, the worm 15 at its front end rotates accordingly. Since there is a meshing relationship between the worm 15 and the turbine 16, the rotation of the worm 15 drives the turbine 16 to rotate. The turbine 16 is fixedly connected to the conveying roller 3, so the rotation of the turbine 16 drives the conveying roller 3 to rotate. The rotation of the conveying roller 3 can smoothly transport the extruded board produced by the barrel 4 to the subsequent process.

A motor 1 7 is installed on the bottom side of the gear 8 and the top side of the crushing chamber 6 through a fixing frame, and the driving end of the motor 1 7 is fixedly connected to the top side of the driving gear 32. A motor 2 13 is installed on the rear end of the bottom plate 1 through a fixing frame, and the driving end of the motor 2 13 is fixedly connected to the rear end of the transmission rod 14, so as to crush the raw materials inside the crushing chamber 6. A guide cover 10 is fixedly connected to the bottom side of the crushing chamber 6, and a discharge pipe 18 is fixedly connected to the bottom end of the guide cover 10, and a feed pipe 9 is fixedly connected to the outer wall of the crushing chamber 6; Specifically, in the extruded board production equipment, the crushing chamber 6 is installed at the rear end of the top side of the base plate 1 through a support frame, and is used to crush the raw materials. The inner wall of the top side of the crushing chamber 6 is rotatably connected to the crushing shaft 31, and the outer wall of the crushing shaft 31 is provided with a plurality of crushing blades for physically cutting and crushing the raw materials.

In the production process of the extruded board, the raw materials are first conveyed into the crushing chamber 6 through the feed pipe 9. The motor 7 is started, and its power output end drives the driving gear 32 to rotate. Since there is a meshing relationship between the driving gear 32 and the driven gear 8, the rotation of the driving gear 32 will not only drive the crushing shaft 31 directly connected to it to rotate, but also drive other crushing shafts 31 to rotate through the driven gear 8. Due to the meshing characteristics of the driving gear 32 and the driven gear 8, the crushing shaft 31 connected to the bottom side of the driving gear 32 rotates in the opposite direction to the other crushing shafts 31. This opposite rotation direction can cause the raw materials to be sheared and squeezed in multiple directions in the crushing chamber 6, thereby efficiently completing the crushing process of the raw materials. The crushed raw materials are temporarily stored in the crushing chamber 6, waiting for further processing in subsequent processes.
