Abstract
Description
Technical Field
[0001] This utility model relates to the field of composite fabric technology, and in particular to a melt blending device for environmentally friendly composite fabrics. Background Technology
[0002] The melt blending device for environmentally friendly composite fabrics is a core piece of equipment used to mix and homogenize various polymer raw materials (often combined with environmentally friendly modifiers, recycled materials, etc.) in a molten state, providing homogeneous blended materials for the subsequent preparation of environmentally friendly composite fabrics. It is widely used in the production process of environmentally friendly fabrics such as recycled polyester and bio-based polymers.
[0003] First, various environmentally friendly raw materials (such as recycled polyester granules, polylactic acid (PLA) resin, environmentally friendly compatibilizers, etc.) are dried and then fed into the melting and plasticizing unit by a metering feeding device according to a preset ratio. The barrel heating causes the raw materials to gradually melt into a viscous flow state. The shearing and conveying action of the screw propels the material forward. During this process, different components come into full contact and undergo physical fusion, and environmentally friendly additives are evenly dispersed in the substrate. Subsequently, the melt blend is further homogenized by the mixing and homogenizing unit, and finally, it is discharged through the discharge unit to form a material form that meets the requirements of subsequent fabric processing, laying the foundation for the formation of environmentally friendly composite fabrics (such as spinning, calendering, etc.).
[0004] The above-mentioned device has the following defects: the production of environmentally friendly composite fabrics often involves special raw materials such as recycled materials and bio-based materials. Recycled materials have many impurities, uneven molecular weight distribution, and often contain moisture. During melting, local overheating and carbonization are prone to occur, or precipitation is prone to occur due to vertical stirring, resulting in defects in the blended materials or loss of biodegradability. Therefore, a melt blending device for environmentally friendly composite fabrics is proposed to solve the above problems. Summary of the Invention

Recycled materials have many impurities, uneven molecular weight distribution, and often contain moisture. During melting, local overheating and carbonization are prone to occur, or precipitation is prone to occur due to vertical stirring.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a melt blending device for environmentally friendly composite fabrics, comprising a fixed column and a frame, the frame contacting the outer side wall of the fixed column, a melt blending mixing tank body fixedly connected to the outer side wall of the fixed column, an adjustment mechanism and an auxiliary mechanism provided on the frame, the adjustment mechanism including a drive motor, the drive motor fixedly connected to the right outer wall of the frame, an eccentric plate fixedly connected to the output end of the drive motor via a coupling, a linkage plate hinged to the outer side wall of the eccentric plate, a movable plate hinged to the right outer wall of the linkage plate, a movable column rotatably connected to the left inner wall of the frame via a bearing, a torsion spring fixedly connected to the outer side wall of the movable column, a fixed rod fixedly connected to the outer side wall of the movable column, and a baffle fixedly connected to the left outer wall of the frame.
[0007] As a further description of the above technical solution: the auxiliary mechanism includes a slide groove, which is formed on the bottom outer wall of the frame. The front and rear inner walls of the slide groove are slidably connected to a bracket. The top outer wall of the bracket is fixedly connected to a spring damper.

[0008] As a further description of the above technical solution: the movable plate is fixedly connected to the outer side wall of the fixed column, and the fixed column is rotatably connected to the inner walls of the left and right sides of the frame through bearings.

[0013] This utility model has the following beneficial effects: 1. In this utility model, through the coordinated action of various components of the adjustment mechanism, the blending uniformity of the relevant mixtures for environmentally friendly composite fabrics can be effectively improved and the feeding operation can be simplified. The power output by the drive machine is transmitted in an orderly manner through the skew plate, linkage plate and movable plate, which can drive the main body of the melt blending mixing tank to swing, thereby avoiding the formation of sediment due to gravity accumulation of the mixture during the mixing process, ensuring the uniformity of the composition of the environmentally friendly composite fabric produced in the subsequent production, and thus improving the quality of the finished fabric. At the same time, the torsion spring, the fixed rod and the baffle cooperate with each other to stably drive the main body of the melt blending mixing tank to return to the initial state after swinging, providing convenience for the operators to feed materials in the subsequent process, reducing the situation of material residue or spillage during the feeding process, and improving the overall processing efficiency.
[0014] In this invention, the spring damper can efficiently absorb the vibration transmitted to the frame during the operation of the molten blending mixing tank, preventing long-term vibration from causing loosening of the connecting parts or damage to the components, thus extending the overall service life of the device. It can also reduce the noise generated by vibration and improve the working environment. The rollers can easily move the entire device to a different position. With the locking and limiting structure of the pins and through holes, the device position can be quickly fixed to prevent displacement during operation. The switching between movement and fixation can be completed without the need for additional tools, greatly reducing the difficulty of operation for personnel. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Reference Figures 1-3 This utility model provides an embodiment of a melt blending device for environmentally friendly composite fabrics, comprising a fixed column 1 and a frame 2. The frame 2 contacts the outer side wall of the fixed column 1, and a melt blending mixing tank body 3 is fixedly connected to the outer side wall of the fixed column 1. An adjustment mechanism 4 and an auxiliary mechanism 5 are provided on the frame 2. The adjustment mechanism 4 includes a drive motor 41, which is fixedly connected to the right outer wall of the frame 2. The output end of the drive motor 41 is fixedly connected to an inclined plate 42 via a coupling. The coupling enables smooth transmission of power from the drive motor 41, ensuring accurate transmission of the rotational power of the drive motor 41. The load is transferred to the slant plate 42, which can rotate synchronously with the output end of the drive motor 41. A linkage plate 43 is hinged to the outer side wall of the slant plate 42, and a movable plate 44 is hinged to the outer right side wall of the linkage plate 43. A movable column 46 is rotatably connected to the inner left side wall of the frame 2 through a bearing. A torsion spring 47 is fixedly connected to the outer side wall of the movable column 46. The torsion spring 47 is bound to the movable column 46, so that the elastic deformation of the torsion spring 47 can directly drive the movable column 46 to rotate, thus reserving elastic force for the reset function of the device. A fixing rod 48 is fixedly connected to the outer side wall of the movable column 46, and a baffle 49 is fixedly connected to the outer left side wall of the frame 2.
[0019] Reference Figures 2-4 The movable plate 44 is fixedly connected to the outer side wall of the fixed column 1. The fixed column 1 is rotatably connected to the inner walls of the left and right sides of the frame 2 through bearings. The end of the torsion spring 47 away from the movable column 46 is fixedly connected to the outer left side wall of the frame 2. The movable column 46 is rotatably connected to the outer left side wall of the frame 2 through bearings. Wear-resistant sleeves are fixedly connected to the outer side walls of the fixed rod 48 and the baffle 49. The wear-resistant sleeves enhance the wear resistance of the contact part between the fixed rod 48 and the baffle 49, and prevent the surface from being damaged due to long-term collision and friction. The fixed rod 48 contacts the outer side wall of the baffle 49.
[0020] Reference Figures 3-4The auxiliary mechanism 5 includes a slide 51, which is formed on the bottom outer wall of the frame 2. Supports 52 are slidably connected to the inner walls of the front and rear sides of the slide 51. A spring damper 53 is fixedly connected to the top outer wall of the support 52. The spring damper 53 is firmly connected to the support 52, enabling it to absorb vibrations transmitted between the support 52 and the frame 2 in a timely manner, thus providing a buffering and shock-absorbing effect. A roller 54 is rotatably connected to the bottom inner wall of the support 52 via a bearing. The roller 54 has a through hole 55, and the inner wall of the side of the through hole 55 is engaged with… There is a pin 56 and a spring damper 53. The end of the spring damper 53 away from the bracket 52 is fixedly connected to the bottom inner wall of the frame 2. There are several through holes 55. Several through holes 55 are respectively opened on the outer side wall of the roller 54 and the bracket 52. Multiple through holes 55 can adapt to different rotation angles of the roller 54, so that the pin 56 can limit the roller 54 at different positions. A frosted sleeve is fixedly connected to the outer side wall of the pin 56. The frosted sleeve increases the friction between the pin 56 and the inner wall of the through hole 55, preventing the pin 56 from falling off by itself when the device vibrates.
[0021] Working principle: By turning on the drive motor 41, the slant plate 42 rotates. The rotation of the slant plate 42 pulls the linkage plate 43 to move. The movement of the linkage plate 43 drives the movable plate 44 to move. The movement of the movable plate 44 causes the fixed column 1 to rotate slightly. The back-and-forth rotation of the fixed column 1 causes the main body 3 of the melt-blending mixing tank to swing, preventing sedimentation of the various mixtures during mixing. At the same time, the torsion spring 47 twists the fixed rod 48 to reset the main body 3 of the melt-blending mixing tank to its initial position, making it easy for personnel to unload and remove the mixture inside the main body 3 of the melt-blending mixing tank. Meanwhile, the spring damper 53 buffers the vibration force generated by the main body 3 of the melt-blending mixing tank to the frame 2. When the whole equipment needs to be moved, it can be moved easily by the rollers 54. At the same time, the rollers 54 are limited by inserting the pin 56 into the corresponding through hole 55, which facilitates personnel operation and adjustment.
[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
