Description

Technical Field

[0001] The utility model relates to the technical field of extruders, in particular to a heating extruder for producing thermoplastic polyether ester elastomers. Background Art

[0002] Extrusion technology is a production process widely used in the fields of plastics, rubber, and food processing. After melting the raw materials by heating, they are extruded through a mold with a specific shape, which has the advantages of high efficiency, automation, and continuous production. In recent years, with the progress of materials science and engineering technology, the design and functions of extruders have been continuously innovated, especially in intelligent control and energy conservation, and remarkable progress has been made. Modern extruders are equipped with advanced temperature control, pressure monitoring, and data acquisition systems, making the production process more precise and stable.

[0003] During the extrusion process of general thermoplastic polyether esters, due to the need to extrude multiple strip-shaped products at one time, the complexity of the operation and the material properties bring many challenges. After the thermoplastic polyether ester strips are heated and melted, their viscosity is high and they are relatively soft, and the thermoplastic polyether ester strips are prone to the situation of air holes. This leads to the occurrence of fractures when extruding. After the fractures occur, they will accumulate at the extrusion port and contact with other thermoplastic polyether ester strips, resulting in the bonding phenomenon with other thermoplastic polyether ester strips. This kind of bonding will not only cause the failure of the extruder to discharge materials, but also may cause the stagnation of the production line. Such failures not only reduce the extrusion yield, but also increase the production cost, and it is also necessary to frequently clean the equipment and readjust the process parameters. Therefore, when the thermoplastic polyether ester strips break, they need to be processed in time. Summary of the Utility Model

[0004] The utility model discloses a heating extruder for producing thermoplastic polyether ester elastomers, aiming to solve the technical problems put forward in the background art.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A heating extruder for producing thermoplastic polyether ester elastomers includes a housing. It is characterized in that a water tank is fixedly connected to the upper surface of the other end of the housing, an outlet block is fixedly connected to the outer wall of the other end of the housing, a plurality of outlet holes are arranged inside the outlet block, polyether ester strips are extruded at the outlet holes, a conduit is inserted into one side of the water tank, a cutter capable of moving horizontally and vertically is arranged at the position of the outlet holes, a guide rod is fixedly connected to one side of the moving frame near the second motor, a cooling cylinder is fixedly connected to one side of the cutter, a connecting pipe is inserted into the upper surface of the moving cooling cylinder, a camera is fixedly connected to the bottom of one side of the moving frame, an outlet groove is arranged at the bottom of the cooling cylinder, and the other end of the connecting pipe is inserted into the conduit.

[0007] In a preferred embodiment, a slide rail is fixedly connected to the upper surface of the discharge block. The slide rail is slidably connected to the moving frame. One end of the discharge block is fixedly connected to a first motor. One end of the output shaft of the first motor is fixedly connected to a first threaded rod for the lateral movement of the moving frame. A second motor is fixedly connected to the outer wall of one side of the moving frame. One end of the output shaft of the second motor is fixedly connected to a second threaded rod for driving the cutter and the cooling cylinder to move longitudinally.

[0008] In a preferred embodiment, a feeding motor is fixedly connected to the outer wall of one end of the outer shell.

The other end of the conduit is inserted into the bottom of the other side of the moving frame.

[0009] As can be seen from the above, a hot - plastic polyether ester elastomer production heating and extrusion machine provided by the present utility model has the following technical effects.

[0010] Firstly: By using a camera to photograph the states of multiple polyether ester strips, through image recognition technology, the position of the broken polyether ester strip is identified by the camera. The moving frame drives the cooling cylinder to stop above the broken polyether ester strip, makes the cutter move downward, and uses the bottom of the cutter to cut off the broken polyether ester strip. The cooling cylinder is stopped at the discharge hole where the broken polyether ester strip is located, so that the continuously extruded polyether ester strip enters the inside of the cooling cylinder. The conduit and the connecting pipe discharge the water in the water tank into the cooling cylinder, so that the newly extruded polyether ester strip is cooled inside the cooling cylinder and discharged from the discharge slot at the bottom of the cooling cylinder. At this time, the polyether ester strip has been cooled and will not adhere to other polyether ester strips, can automatically process the broken polyether ester strip, and prevent the polyether ester strips from sticking to each other.

[0020] In this embodiment, polyetherester raw material is added into the raw material barrel 5, and the polyetherester raw material enters the interior of the conveying cylinder 8 through the bottom of the raw material barrel 5. The bolt feeding motor 6 is started to drive the conveying screw 7 to rotate, so that the polyetherester raw material is continuously conveyed forward, and multiple heating rings 9 are energized to heat the heat-conducting cylinder 10. The heat-conducting cylinder 10 transfers heat to the conveying cylinder 8. The conveying cylinder 8 heats the internal polyetherester raw material to melt the polyetherester raw material into a molten state. The molten polyetherester raw material is extruded through multiple discharge holes on the discharge block 2 to form multiple polyetherester strips 3.

Since the polyetherester strips 3 have been cooled at this time, they will not accumulate at the extrusion port position, nor will they adhere to other polyetherester strips 3, which has the effect of timely and automatically processing the broken polyetherester strips 3 and preventing the polyetherester strips 3 from sticking to each other. After processing the broken polyetherester strips 3, the camera 13 will be reset.

[0022] Specifically, the cutter 25 is slidably connected to the movable frame 16 , and a chamfer is provided at the bottom of the cutter 25 , and the chamfer edge of the bottom of the cutter 25 is sharp.

[0023] Specifically, a threaded hole 18 is provided at the bottom of the mobile frame 16 near the first threaded rod 12 , and the first threaded rod 12 is threadedly connected to the threaded hole 18 .

[0024] Specifically, a shock-absorbing base 19 is provided at the bottom of the outer shell 1 to reduce the vibration noise of the device and improve the service life and stability of the device.

[0025] Working principle: When in use, polyether ester raw materials are added into the raw material barrel 5. The polyether ester raw materials enter the inside of the conveying barrel 8 through the bottom of the raw material barrel 5. The feeding motor 6 is started to drive the conveying screw 7 to rotate, so that the polyether ester raw materials are continuously conveyed forward. The heating rings 9 are powered on to heat the heat conduction barrel 10. The heat conduction barrel 10 transfers the heat to the conveying barrel 8. The conveying barrel 8 heats the polyether ester raw materials inside, so that the polyether ester raw materials are melted into a molten state. The molten polyether ester raw materials are extruded through a plurality of discharge holes on the discharge block 2 to form a plurality of polyether ester strips 3. During the process of the molten polyether ester raw materials being conveyed inside the conveying barrel 8, bubbles may be generated. The bubbles cause the inside of the polyether ester strips 3 to be hollow or have surface defects, resulting in possible breakage when the polyether ester strips 3 are extruded from the discharge holes of the discharge block 2. If breakage occurs, the set camera 13 can photograph and identify the states of the plurality of polyether ester strips 3. Through image recognition technology, the position of the broken polyether ester strip 3 is identified, and the controller is used to control the first motor 11 to drive the first threaded rod 12 to rotate, thereby driving the moving frame 16 to move back and forth. The moving frame 16 drives the cooling barrel 15 to stop above the broken polyether ester strip 3. The second motor 23 is controlled to drive the second threaded rod 22 to rotate, so that the cutting knife 25 moves downward, and the broken polyether ester strip 3 is cut off by the cutting knife 25. Since a discharge groove 14 is provided at the bottom of the cooling barrel 15, the cooling barrel 15 is stopped at the discharge hole of the position where the broken polyether ester strip 3 is located, so that the continuously extruded polyether ester strips 3 enter the inside of the cooling barrel 15. At this time, the conduit 17 and the connecting pipe 21 discharge the water inside the water tank 4 into the cooling barrel 15, so that the newly extruded polyether ester strips 3 are cooled inside the cooling barrel 15 and discharged from the discharge groove 14 at the bottom of the cooling barrel 15. At this time, the polyether ester strips 3 are initially cooled by the cooling barrel 15, so that the strength of the discharge state is increased, the generation of breakage is prevented, and at the same time, they will not adhere to other polyether ester strips 3. The newly extruded polyether ester strips 3 will fall into the water tank below for further cooling after being cooled, and it is necessary to manually clean the broken polyether ester strips 3 and pull the newly extruded polyether ester strips 3 forward until the polyether ester strips 3 come into contact with the subsequent conveying mechanism, and the conveying mechanism is responsible for pulling the polyether ester strips 3 forward.

The substitution may be the substitution of some structures, devices, and method steps, or a complete technical solution.
