Description

Technical Field

[0001] The invention belongs to the field of textile technology, and in particular relates to a regenerated colored polyester staple fiber for automobile engine felt and a production device thereof. Background Art

[0002] Car engine felt refers to the sound insulation and heat insulation material installed in the car engine compartment. In order to improve resource utilization, the current car engine felt can be made of recycled colored polyester staple fibers. Recycled polyester fiber refers to the use of polyester fabrics, waste polyester bottle pieces, spinning waste, foam materials, and pulp blocks as raw materials. The waste bottle pieces are crushed and cleaned, and the mixture of various materials is dried, melt extruded, spun, wound, bundled, drawn, curled, relaxed, heat-set, and cut to form polyester staple fibers of different lengths.

[0003] The current recycled colored polyester staple fibers have a short service life in practical applications due to the influence of external environment, such as humidity and temperature. At the same time, in the production process of recycled colored polyester staple fiber fabrics, the dried raw materials need to be transported to the extruder for fusion extrusion. However, due to the plasticity of the raw materials, the material is easily stuck during the transportation process, which affects the production efficiency of the production equipment and needs to be improved. Summary of the invention

[0004] The purpose of the present invention is to provide a regenerated colored polyester staple fiber for automobile engine felt and a production device thereof with high structural strength, strong waterproofness and high production efficiency in view of the deficiencies in the prior art.

[0005] In order to achieve the above technical purpose, the technical solution adopted by the regenerated colored polyester staple fiber for automobile engine felt and the production device thereof of the present invention is as follows: A recycled colored polyester staple fiber for automobile engine felt comprises a staple fiber layer, a first reinforcement layer is arranged on one side of the staple fiber layer, and a second reinforcement layer is arranged on the other side, a heat insulation layer is arranged on the side of the first reinforcement layer facing away from the staple fiber layer, and an antistatic layer is arranged on the side of the second reinforcement layer facing away from the staple fiber layer, and a waterproof edging is arranged around the outer sides of the heat insulation layer, the first reinforcement layer, the staple fiber layer, the second reinforcement layer and the antistatic layer which are arranged in sequence.

[0006] By adopting the above technical scheme, the first reinforcement layer and the second reinforcement layer improve the overall structural strength of the recycled colored polyester staple fiber, the heat insulation layer makes the recycled colored polyester staple fiber as a whole less susceptible to the influence of external temperature, the antistatic layer makes the recycled colored polyester staple fiber less susceptible to static electricity, and the waterproof edging makes the recycled colored polyester staple fiber less susceptible to external humidity, thereby improving the overall service life of the recycled colored polyester staple fiber.

[0007] Preferably, the first reinforcement layer and the second reinforcement layer are both provided with nylon braided layers.

[0008] Preferably, the heat insulating layer is configured as a glass fiber layer.

[0009] In a second aspect, the present application also provides a production device, which adopts the following technical solution: A production device comprises a feed cylinder and a feeding cylinder, wherein the feed cylinder is connected with the feeding cylinder, the feed cylinder is arranged on the feeding cylinder in a vertical direction, a conveying component for conveying raw materials is arranged in the feeding cylinder, and a dredging component for dredging raw materials is arranged in the feed cylinder.

[0010] By adopting the above technical solution, during the process of conveying raw materials, the dredging component is started regularly to dredge the raw materials in the feed barrel, so that the phenomenon of material accumulation is not easy to occur in the feed barrel. The raw materials entering the feed barrel are conveyed to the next station for fusion by the conveying component. Under the action of the dredging component, the raw materials can enter the feed barrel more stably, thereby improving the overall efficiency of the production device.

[0011] Preferably, the dredging assembly includes a cover plate, a box body and a plurality of dredging rods, the cover plate is arranged on the box body, a vibration assembly is provided in the box body, the plurality of dredging rods are arranged on a side of the cover plate close to the box body, each of the dredging rods extends out of the box body, each of the dredging rods is threadedly connected with a nut, and each of the nuts is in contact with the box body.

[0012] By adopting the above technical solution, the vibration component starts and controls the vibration of the box body and the cover plate. Since the dredging rods are located on the cover plate, the vibration of the cover plate drives each dredging rod to vibrate. During the vibration of the dredging rods, thrust is applied to the raw materials, making it less likely for the raw materials in the feed barrel to be blocked.

[0013] Preferably, a clearance hole is opened on the feeding barrel, a connecting block is slidably connected in the clearance hole, a connecting rod is provided on one side of the connecting block, and a connecting plate is provided on the other side, the end of the connecting rod away from the connecting block is connected to the box body, a support is provided on the feeding barrel, a spring is provided on the support, and the end of the spring away from the support is connected to the connecting plate.

[0014] By adopting the above technical solution, the connecting rod and the connecting block provide support for the box body during the vibration of the box body. At the same time, the connecting block moves along the clearance hole, which improves the stability of the box body during vibration, that is, improves the stability of the dredging rod during operation. At the same time, under the action of the spring, the vibration amplitude of the box body is increased, that is, the vibration amplitude of the dredging rod is increased, thereby providing convenience for the dredging rod to dredge the raw materials more stably.

[0015] Preferably, the vibration assembly includes a support plate, a vibration motor and a battery. A support block is provided in the box body, the support plate is abutted against the support block, each of the dredging rods passes through the support plate, the vibration motor is arranged on the support plate, and the battery is arranged on the side of the support plate away from the vibration motor.

[0016] By adopting the above technical solution, the worker places the vibration motor and the battery on both sides of the support plate, and then places the support plate on the support block. The worker then covers the cover plate on the box body, so that each dredging rod passes through the support plate and the box body in sequence. The worker then uses nuts to fix the dredging rod to complete the assembly of the dredging assembly, thereby facilitating the assembly of the dredging assembly.

[0017] Preferably, each of the dredging rods is provided with a limit plate, and each of the limit plates abuts against a side of the support plate away from the vibration motor.

[0018] By adopting the above technical solution, after the box body is fixed, the limiting plate abuts against the support plate to provide a limit for the support plate, making it difficult for the support plate to be displaced during subsequent use, thereby improving the stability of the dredging component during operation.

[0019] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention provides a first reinforcement layer, a second reinforcement layer and a waterproof edging. The first reinforcement layer and the second reinforcement layer improve the overall structural strength of the recycled colored polyester staple fiber. The waterproof edging improves the overall waterproof performance of the recycled colored polyester staple fiber, so that the recycled colored polyester staple fiber is not easily affected by the external environment. 2. The present invention provides a dredging component and a vibration component. The vibration component provides power for the dredging component, which facilitates the dredging component to dredge the raw materials in the feed barrel, reduces the possibility of raw material accumulation, and enables the conveying component to more stably convey the raw materials to the next station for fusion, thereby improving the production efficiency of the production device; 3. The present invention provides a limit plate. After the cover plate and the box body are fixed, the limit plate provides a limit for the support plate, thereby reducing the possibility of movement of the support plate during subsequent use.

DETAILED DESCRIPTION

[0022] The invention is further described below in conjunction with the accompanying drawings and specific embodiments: like Figure 1 As shown, the present invention discloses a regenerated colored polyester staple fiber for automobile engine felt. Figure 1 A recycled colored polyester staple fiber for automobile engine felt comprises a staple fiber layer 1, a first reinforcing layer 2 is arranged on one side of the staple fiber layer 1, and a second reinforcing layer 3 is arranged on the other side. A heat insulating layer 21 is arranged on the side of the first reinforcing layer 2 facing away from the staple fiber layer 1, and an antistatic layer 31 is arranged on the side of the second reinforcing layer 3 facing away from the staple fiber layer 1. A waterproof edging 4 is wound around the outer sides of the heat insulating layer 21, the first reinforcing layer 2, the staple fiber layer 1, the second reinforcing layer 3 and the antistatic layer 31 which are arranged in sequence, and the staple fiber layer 1 is arranged as a polyester staple fiber layer 1, and the waterproof edging 4 is made of rubber.

[0023] Reference Figure 1 The first reinforcement layer 2 and the second reinforcement layer 3 are both configured as nylon fiber layers. Nylon fiber has a relatively high structural strength, thereby improving the overall structural strength of the recycled colored polyester staple fiber.

[0024] The heat insulating layer 21 is configured as a glass fiber layer. The glass fiber has good heat insulating ability, so that the recycled colored polyester staple fiber as a whole is not easily affected by the external temperature, thereby increasing the service life of the recycled colored polyester staple fiber as a whole.

[0025] The antistatic layer 31 is configured as a bamboo charcoal fiber layer. The bamboo charcoal fiber has good insulation performance, thereby improving the overall antistatic ability of the recycled colored polyester staple fiber.

[0026] The implementation principle of the recycled colored polyester staple fiber for automobile engine felt in an embodiment of the present invention is as follows: the first reinforcement layer 2 and the second reinforcement layer 3 improve the overall structural strength of the recycled colored polyester staple fiber, the heat insulation layer 21 makes the recycled colored polyester staple fiber as a whole less susceptible to the external environment, the antistatic layer 31 improves the overall antistatic ability of the recycled colored polyester staple fiber, and the waterproof edging 4 makes the recycled colored polyester staple fiber as a whole less susceptible to the external humidity, thereby improving the overall service life of the recycled colored polyester staple fiber.

[0027] In a second aspect, an embodiment of the present invention further discloses a production device.

[0028] Reference Figure 2 and Figure 3 The production device includes a feed barrel 5 and a feeding barrel 6. The feed barrel 5 is connected to the feeding barrel 6 and is vertically arranged on the feeding barrel 6. The feeding barrel 6 is provided with a conveying assembly 61 for conveying raw materials, and the feed barrel 5 is provided with a dredging assembly 51 for dredging raw materials.

[0029] Reference Figure 2 The conveying assembly 61 includes an auger 611 and a drive motor 612. The auger 611 is rotatably connected to the feeding barrel 6. The drive motor 612 is fixed outside the feeding barrel 6, and the output end of the drive motor 612 is coaxially fixed with the rotating shaft of the auger 611. When the raw material moves into the feeding barrel 6, the drive motor 612 controls the auger 611 to rotate, and the raw material can be conveyed to the next station for fusion.

[0030] Reference Figure 2 and Figure 3 The dredging assembly 51 includes a cover plate 511, a box body 512 and a plurality of dredging rods 513. The cover plate 511 is disposed on the box body 512. The box body 512 is provided with a vibration assembly 7. The plurality of dredging rods 513 are all disposed on a side of the cover plate 511 close to the box body 512, and each dredging rod 513 extends out of the box body 512. Each dredging rod 513 is threadedly connected with a nut 52, and each nut 52 abuts against the box body 512.

[0031] When the dredging assembly 51 needs to be installed, the worker places the vibration assembly 7 in the box body 512, and then covers the cover plate 511 on the box body 512, so that each dredging rod 513 extends out of the box body 512. The worker then installs the nut 52 on each dredging rod 513, so that each nut 52 abuts against the box body 512, and the installation between the cover plate 511, the box body 512 and each dredging rod 513 is completed.

[0032] Reference Figure 2The feed barrel 5 is provided with a clearance hole 53, in which a connecting block 531 is slidably connected. A connecting rod 532 is connected to one side of the connecting block 531, and a connecting plate 533 is fixed to the other side. The end of the connecting rod 532 away from the connecting block 531 is connected to the box body 512. A support 54 is fixed to the feed barrel 6, and a spring 541 is provided on the support 54. The end of the spring 541 away from the support 54 is connected to the connecting plate 533.

[0033] During the operation of the vibration assembly 7, the box body 512 vibrates and drives the connecting rod 532 and the connecting block 531 to vibrate. At this time, the clearance hole 53 provides a guide for the connecting block 531, thereby improving the stability of the connecting block 531, the connecting rod 532 and the box body 512 during vibration, that is, improving the stability of each dredging rod 513 during operation. In addition, during the vibration of the connecting block 531, since the connecting plate 533 is connected to the spring 541, under the action of the elastic force of the spring 541, the vibration amplitude of the box body 512, the connecting rod 532, the connecting block 531 and the connecting plate 533 is increased, that is, the vibration amplitude of the dredging rod 513 is increased, thereby improving the dredging efficiency of the dredging assembly 51.

[0034] Reference Figure 2 Both sides of the connecting block 531 are connected with corrugated plates 55 , and the sides of the two corrugated plates 55 away from the connecting block 531 are connected to the inner wall of the clearance hole 53 , so that the corrugated plates 55 prevent the raw materials from leaking out of the feeding barrel 5 .

[0035] Reference Figure 2 and Figure 3 The vibration assembly 7 includes a support plate 71, a vibration motor 72 and a battery 73. A support block 56 is provided in the box body 512. The support plate 71 abuts against the support block 56, and each dredging rod 513 passes through the support plate 71. The vibration motor 72 is provided on the support plate 71, and the battery 73 is provided on a side of the support plate 71 away from the vibration motor 72. The battery 73 is electrically connected to the vibration motor 72.

[0036] The storage battery 73 supplies power to the vibration motor 72 . When the vibration motor 72 is working, it can drive the box body 512 , the cover plate 511 and each dredging rod 513 to vibrate. The vibration of the dredging rod 513 can dredge the raw materials in the feed barrel 5 .

[0037] Reference Figure 2 and Figure 3 In order to improve the stability of the support plate 71 when in use, a limit plate 57 is fixed on each dredging rod 513, and each limit plate 57 abuts against the side of the support plate 71 away from the vibration motor 72.

[0038] During the assembly of the dredging assembly 51, the cover plate 511 covers the box body 512, and each dredging rod 513 passes through the support plate 71 and the box body 512 in sequence. When the limiting plate 57 abuts against the support plate 71, the cover plate 511 abuts against the box body 512. At this time, the limiting plate 57 provides a limit for the support plate 71, reducing the possibility of the limiting plate 57 moving during use.

[0039] The implementation principle of a production device of an embodiment of the present invention is: in the process of conveying raw materials, the vibration component 7 provides power to the unblocking component 51, and the unblocking component 51 can dredge the raw materials in the feed barrel 5, reducing the phenomenon of blockage of the raw materials, so that the conveying component 61 can more stably convey the raw materials to the next workstation for fusion, thereby improving the production efficiency of the production device.

[0040] In summary, the above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention.
