Description

Technical Field

[0001] This invention relates to the field of plastic extrusion technology, and more particularly to a meltblown fabric plastic particle extrusion device with a constant temperature hopper. Background Technology

[0002] Meltblown nonwoven fabric is the core material of face masks. It is primarily made of polypropylene, with fiber diameters ranging from 1 to 5 micrometers. Its numerous pores, loose structure, and excellent wrinkle resistance, combined with its unique capillary structure, increase the number of fibers and surface area per unit area, giving meltblown nonwoven fabric excellent filtration, shielding, heat insulation, and oil absorption properties. It can be used in air and liquid filtration materials, isolation materials, absorbent materials, face mask materials, thermal insulation materials, oil-absorbing materials, and wiping cloths. The polypropylene raw material for meltblown nonwoven fabric needs to be extruded using a plastic extruder. However, current extrusion equipment hoppers lack insulation; the raw material in the hopper is heated only after entering the extrusion equipment, affecting extrusion efficiency.

[0003] To address the aforementioned issues, this application proposes a meltblown fabric plastic particle extrusion device with a constant-temperature hopper. Summary of the Invention

This device can preheat the raw materials, improve working efficiency, and adjust the length of the stirring rod to stir different positions of the feeding component, so that the raw materials are heated evenly and the adhesion of the raw materials is prevented.

[0006] (II) Technical Solution

[0007] To solve the above-mentioned technical problems, the present invention provides a meltblown fabric plastic particle extrusion device with a constant temperature hopper, including a base, a support base, a feeding assembly and an extrusion assembly;

[0008] The support base is installed on the ground, and the machine base is set on the support base; the machine base is equipped with a drive device that drives the extrusion assembly to run; the support base is equipped with a support frame, and the extrusion assembly is installed on the support frame; the extrusion assembly is provided with an opening that communicates with the feeding assembly; the feeding assembly is installed on the extrusion assembly, and the output end of the feeding assembly is connected to the opening of the extrusion assembly.

[0009] The feeding assembly includes a feeding hopper and a mounting plate disposed on the feeding hopper; the mounting plate is disposed at the inlet of the feeding hopper; push-pull plates are disposed on both sides of the mounting plate; handles are disposed on the push-pull plates; a drive motor is disposed on the mounting plate, and a stirring rod is disposed at the output end of the drive motor; a mounting groove for the stirring rod to pass through is disposed on the mounting plate; the stirring rod is inserted into the inside of the feeding hopper; multiple stirring blades are disposed at the bottom of the stirring rod.

[0010] A control panel is installed at the bottom of the mounting plate; a heating sleeve is vertically installed on the side of the mounting plate facing the inside of the feed funnel; a bearing is installed in the heating sleeve; the stirring rod is rotatably connected to the bearing; the stirring rod passes through the heating sleeve, and heat exchange occurs between the stirring rod and the heating sleeve.

[0011] The heating sleeve is equipped with multiple heating units, which are electrically connected in parallel; each heating unit is equipped with a power supply line, which is electrically connected to the control panel.

[0012] Preferably, a heat insulation plate is provided on the inner wall of the feed funnel.

[0013] Preferably, the feed hopper is provided with a filling layer, which is a glass fiber layer.

[0014] Preferably, the handle is magnetically attracted to the inner wall of the feed funnel.

[0015] Preferably, the heating sleeve integrates a temperature monitoring module, which is connected to the control panel via a signal.

[0016] Preferably, the stirring rod is divided into several sections; each section is provided with connectors at equal intervals; the sections and connectors slide up and down in the vertical direction.

[0017] Preferably, each segment has an electromagnet at its bottom, and a signal line is provided on the electromagnet, which is connected to the control panel.

[0018] Preferably, a limiting block is provided at the bottom of the connector, and the limiting block is magnetically attracted to the electromagnet.

[0019] Preferably, the stirring rod and the connector are hollow inside.

[0020] Preferably, a mechanical seal is provided on the wall of the mounting groove.

[0021] The above-described technical solution of the present invention has the following beneficial technical effects:

[0022] 1. The heat insulation board serves to maintain a uniform temperature inside the feed hopper, reducing heat loss. The feed hopper contains a filling layer made of glass fiber. The diameter of a single glass fiber filament ranges from a few micrometers to over twenty micrometers, equivalent to 1 / 20 to 1 / 5 the diameter of a human hair. Each bundle of fiber consists of hundreds or even thousands of filaments. Glass fiber is commonly used as a reinforcing material in composite materials, as well as an electrical insulator and a thermal insulation material.

[0023] 2. The handle is magnetically attracted to the inner wall of the feed funnel. This magnetic attraction ensures the feed inlet of the feeding assembly remains closed when no material is being added, reducing heat loss and helping to maintain a balanced temperature. The magnetic connection also makes opening and closing very convenient.

[0024] 3. The stirring rod is divided into several sections; each section has connectors evenly spaced; the sections and connectors slide vertically up and down. Each section has an electromagnet at its bottom, with a signal line connected to the control panel. A limit block is located at the bottom of each connector, attracting the electromagnet magnetically. When the electromagnet is energized, it generates a force that pulls the limit block on the connector, causing the sections on the stirring rod to move upwards, eventually causing the two sections to stick together. By controlling the number of sections sticking together, the length of the stirring rod can be adjusted, allowing for stirring at different positions of the feeding assembly, ensuring uniform heating of the raw materials while preventing them from sticking together.

[0025] 4. A mechanical seal is installed on the wall of the mounting slot. The mechanical seal improves the sealing performance at the mounting plate. Attached Figure Description

It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0033] like Figure 1-5 As shown, the present invention proposes a meltblown fabric plastic particle extrusion device with a constant temperature hopper, including a base 1, a support base 6, a feeding assembly 2 and an extrusion assembly 7.

[0034] The support base 6 is installed on the ground, and the machine base 1 is set on the support base 6; the machine base 1 is equipped with a drive device for driving the extrusion assembly 7 to run; the support base 6 is equipped with a support frame, and the extrusion assembly 7 is installed on the support frame; the extrusion assembly 7 is provided with an opening that communicates with the feeding assembly 2; the feeding assembly 2 is installed on the extrusion assembly 7, and the output end of the feeding assembly 2 is connected to the opening of the extrusion assembly 7.

[0035] The feeding assembly 2 includes a feeding funnel and a mounting plate 3 disposed on the feeding funnel; the mounting plate 3 is disposed at the inlet of the feeding funnel; push-pull plates 5 are disposed on both sides of the mounting plate 3; handles 14 are disposed on the push-pull plates 5; a drive motor 4 is disposed on the mounting plate 3, and a stirring rod 12 is disposed at the output end of the drive motor 4; a mounting groove 15 is disposed on the mounting plate 3 for the stirring rod 12 to pass through; the stirring rod 12 is inserted into the inside of the feeding funnel; multiple stirring blades 13 are disposed at the bottom of the stirring rod 12.

[0036] A control panel 8 is provided at the bottom of the mounting plate 3; a heating sleeve 9 is vertically provided on the side of the mounting plate 3 facing the inside of the feed hopper; a bearing 16 is provided in the heating sleeve 9; the stirring rod 12 is rotatably connected to the bearing 16; the stirring rod 12 passes through the heating sleeve 9, and heat exchange occurs between the stirring rod 12 and the heating sleeve 9.

[0037] The heating sleeve 9 is provided with multiple heating units 17, which are electrically connected in parallel; the heating unit 17 is provided with a power supply line 18, which is electrically connected to the control panel 8.

[0038] In this embodiment, a heat insulation plate 10 is provided on the inner wall of the feed funnel.

[0039] It should be noted that the heat insulation plate 10 can play a role in heat insulation, so that the internal temperature of the feed hopper is kept uniform and heat loss is reduced.

[0040] In this embodiment, a filling layer 11 is provided in the feed funnel, and the filling layer 11 is a glass fiber layer.

[0041] It should be noted that the diameter of a single glass fiber filament ranges from a few micrometers to over twenty micrometers, equivalent to 1 / 20 to 1 / 5 the diameter of a human hair. Each bundle of fiber consists of hundreds or even thousands of single filaments. Glass fiber is commonly used as a reinforcing material in composite materials, as well as an electrical insulation material and a thermal insulation material.

[0042] In this embodiment, the handle 14 is magnetically attracted to the inner wall of the feed funnel.

[0043] It should be noted that the handle 14 is magnetically attracted to the inner wall of the feeding funnel. When no material is needed, the feeding port of the feeding component 2 can be kept closed, reducing heat loss and helping to maintain a balanced temperature. At the same time, the magnetic connection makes it convenient to open and close.

[0044] In this embodiment, a temperature monitoring module is integrated on the heating sleeve 9, and the temperature monitoring module is connected to the control panel 8 via a signal.

[0045] In this embodiment, the stirring rod 12 is divided into several sections; each section is provided with connectors 19 at equal intervals; the sections and connectors 19 slide up and down vertically. Each section has an electromagnet 20 at its bottom, and a signal line 21 is provided on the electromagnet 20, which is connected to the control panel 8. A limit block 22 is provided at the bottom of the connector 19, and the limit block 22 is magnetically attracted to the electromagnet 20.

[0046] It should be noted that when the electromagnet 20 is energized, it generates a suction force, which attracts the limiting block 22 on the connector 19, causing the segments on the stirring rod 12 to move upward, and finally causing the two segments to adhere together. By controlling the number of segments adsorbed together, the length of the stirring rod 12 can be adjusted, and different positions of the feeding component 2 can be stirred, so that the raw materials are heated evenly, while preventing the raw materials from sticking together.

[0047] In this embodiment, the stirring rod 12 and the connector 19 are hollow inside.

[0048] It should be noted that the hollow section facilitates the arrangement of signal lines 21.

[0049] In this embodiment, a mechanical seal is provided on the wall of the mounting groove 15.

[0050] It should be noted that the mechanical seal can improve the sealing performance at mounting plate 3.

[0051] The working principle and usage process of this invention are as follows: Pushing the handle 14 opens the push-pull plate 5, allowing the raw material to be introduced into the feeding assembly 2; then closing the push-pull plate 5, the handle 14 magnetically attracts the inner wall of the feeding funnel, ensuring the feeding port of the feeding assembly 2 remains closed when no material is needed, reducing heat loss and helping to maintain a balanced temperature; the magnetic connection makes opening and closing convenient; the control panel 8 controls the heating unit 17 to heat, raising the temperature of the entire heating sleeve 9; the stirring rod 12 passes through the heating sleeve 9 and exchanges heat with it, thus raising its temperature; subsequently, as the raw material continuously contacts the stirring rod 12, it is preheated, thereby improving heating efficiency; in this invention, the stirring rod 12 is divided into several sections; each section is evenly spaced with connecting parts 19; the sections and connecting parts 19 slide up and down vertically. Each section has an electromagnet 20 at its bottom, with a signal line 21 on the electromagnet 20, which is connected to the control panel 8. A limiting block 22 is provided at the bottom of the connector 19, and the limiting block 22 is magnetically attracted to the electromagnet 20. When the electromagnet 20 is energized, it generates an attractive force, which attracts the limiting block 22 on the connector 19, causing the segments on the stirring rod 12 to move upward, and finally causing the two segments to adhere together. By controlling the number of segments adhering together, the length of the stirring rod 12 can be adjusted to stir different positions of the feeding assembly 2, so that the raw materials are heated evenly and the raw materials are prevented from sticking together. In this invention, a heat insulation plate 10 is provided on the inner wall of the feeding funnel. The heat insulation plate 10 can play a role in heat insulation, so that the internal temperature of the feeding funnel is maintained evenly and heat loss is reduced. A filling layer 11 is provided in the feeding funnel, and the filling layer 11 is a glass fiber layer. The diameter of the glass fiber monofilament is several micrometers to twenty micrometers, which is equivalent to 1 / 20 to 1 / 5 of a human hair. Each bundle of fiber filaments is composed of hundreds or even thousands of monofilaments. Glass fiber is commonly used as a reinforcing material, electrical insulation material and thermal insulation material in composite materials. This invention incorporates a temperature monitoring module to monitor the temperature within the feeding assembly 2. Upon reaching the preset temperature, the control panel 8 controls the heating unit 17 to stop heating, thus saving energy. This invention can preheat raw materials, improving work efficiency. Simultaneously, it allows adjustment of the length of the stirring rod 12 to stir different positions within the feeding assembly 2, ensuring uniform heating of the raw materials and preventing them from sticking together.
