Description

Technical Field

[0001] The invention belongs to the technical field of staple fiber production, and in particular relates to drying equipment used in a polyester staple fiber production line. Background Art

[0002] Polyester fiber, commonly known as "polyester", is a synthetic fiber obtained by spinning polyester formed by the polycondensation of organic dibasic acid and diol. It is abbreviated as PET fiber. It is a polymer compound. It was invented in 1941 and is the largest variety of synthetic fiber. The biggest advantage of polyester fiber is its good wrinkle resistance and shape retention. It has high strength and elastic recovery ability. It is durable, wrinkle-resistant, iron-free, and non-sticky. Chemical staple fibers are commonly known as "short fibers" and "short fibers". Chemical fibers are formed and then cut into a certain length. The products can be divided into cotton-type staple fibers, wool-type staple fibers, and medium-long staple fibers according to the thickness and length. They can be spun purely on cotton, wool and other spinning machines, or blended with cotton, wool and other fibers. Polyester staple fibers need to be cleaned and dried during production.

[0003] When the drying equipment in the prior art dries the short fibers, the short fibers are easily scattered under the action of the airflow after being dried, and are difficult to collect. At the same time, the scattered short fibers also pose a safety hazard. Summary of the invention

[0004] In view of the above-mentioned shortcomings, an object of the present invention is to provide a drying device for a polyester staple fiber production line.

DETAILED DESCRIPTION

[0025] Embodiment 1

[0026] like Figure 1-4 As shown, a drying device for a polyester staple fiber production line includes a base 201 with a receiving groove 206 at the upper end, and the receiving groove 206 is a cylindrical groove. A plurality of drying grooves 207 are provided at the bottom of the receiving groove 206. In this embodiment, the number of the drying grooves 207 is five. A lifting plate 208 connected to a driving mechanism 1 is provided in the drying groove 207. The driving mechanism 1 is used to drive the lifting plate 208 to move up and down. A heating wire 1 209 is installed in the lifting plate 208. When drying the wet staple fibers, the driving mechanism 1 drives the lifting plate 208 to move downward first, and then the wet staple fibers are placed in the drying groove 207, and the heating wire 1 209 is energized, so as to dry the wet staple fibers. Since the staple fibers are placed in the groove, when the staple fibers are dried, they will not be affected by the lateral airflow and fly around. After the staple fibers are dried, the driving mechanism 1 drives the lifting plate 208 to rise until the lifting plate 208 is flush with the bottom of the containing tank 206 , thereby allowing the staple fibers to leave the drying tank 207 .

[0027] Specifically, the driving mechanism 1 includes a cylinder 106, a piston rod of the cylinder 106 is fixedly connected to a lifting ring 107, and the lifting plate 208 is connected to the lifting ring 107 through a guide rod 108. The cylinder 106 can drive the lifting ring 107 to move up and down, thereby driving multiple lifting plates 208 to move up and down synchronously.

[0028] The upper notch of the drying tank 207 is provided with a mesh plate 307 connected to the driving mechanism 3, and the driving mechanism 3 is used to drive the mesh plate 307 to close the upper notch of the drying tank 207. Before the wet staple fibers are placed in the drying tank 207, the mesh plate 307 is not closed in the drying tank 207; when the wet staple fibers are placed in the drying tank 207 for drying, the mesh plate 307 is driven by the driving mechanism 3 to close the notch of the drying tank 207, thereby preventing the staple fibers at the upper end of the drying tank 207 from being scattered under the influence of the airflow after being dried. The mesh holes provided in the mesh plate 307 can facilitate the dissipation of the water vapor generated during drying. After the staple fibers are dried, the mesh plate 307 is not closed in the drying tank 207, and then the lifting plate 208 is raised.

[0029] The receiving groove 206 is centrally provided with a lever 110 connected to a driving mechanism 105, and the driving mechanism 105 is used to drive the lever 110 to rotate. The driving mechanism 105 can use a driving system with a motor as a power source, which is relatively mature in the prior art and will not be described in detail here.

[0030] After the wet staple fibers are placed in the receiving tank 206, the driving mechanism 105 drives the lever 110 to rotate, and the lever 110 can push the wet staple fibers into the drying tank 207 until the drying tank 207 is filled with the staple fibers.

[0031] The bottom of the receiving groove 206 is also provided with an outlet 205, and the upper end of the outlet 205 is provided with a baffle 204 connected to the second driving mechanism 203, and the second driving mechanism 203 is used to drive the baffle 204 to close the outlet 205. The second driving mechanism 203 can be a horizontal linear slide.

[0032] Before the wet staple fibers are placed in the receiving tank 206, the baffle 204 is first used to close the outlet 205. After the staple fibers are dried, the baffle 204 is again used to open the outlet 205, and the lifting plate 208 is raised until the lifting plate 208 is flush with the bottom of the receiving tank 206. Then, the driving mechanism 105 drives the lever 110 to rotate, and the lever 110 pushes the dried staple fibers out of the outlet 205.

[0033] Embodiment 2

[0034] Furthermore, in this embodiment, a mesh cover 102 is installed on the upper end of the base 201, and the mesh cover 102 is provided with an inlet, and a stopper 104 connected to a driving mechanism 5 103 is provided on the upper end of the inlet, and the driving mechanism 5 103 is used to drive the stopper 104 to close the inlet. The driving mechanism 5 103 is a cylinder.

[0035] The conveying line 101 is arranged above the base 201, and the inlet corresponds to the conveying line.

[0036] The mesh cover 102 can prevent the dry staple fibers from scattering from the upper end of the receiving tank 206 when being pushed out of the outlet 205. Before the wet staple fibers are transported from the conveying line 101 to the receiving tank 206, the blocking cover 104 is driven by the driving mechanism 5 103 to open the entrance. After the staple fibers enter the receiving tank 206, the blocking cover 104 is driven to close the entrance.

[0037] Embodiment 3

[0038] Further, in this embodiment, a stirring rod 303 connected to a driving mechanism 6 is provided on the side of the drying tank 207. The driving mechanism 6 is used to drive the stirring rod 303 to extend into the drying tank 207 and drive the stirring rod 303 to rotate.

[0039] During the drying process of the staple fibers in the drying tank 207 , the stirring rod 303 can be extended into the drying tank 207 , and the staple fibers in the drying tank 207 can be stirred by the rotating stirring rod 303 , thereby facilitating the dissipation of water vapor and accelerating the drying speed.

[0040] A cover plate 306 connected to a driving mechanism 7 is provided above the mesh plate 307. The driving mechanism 7 is used to drive the cover plate 306 to close the drying tank 207.

[0041] When most of the staple fibers in the drying tank 207 have been dried, stirring at this time may easily cause the staple fibers to fly away. Therefore, the cover plate 306 is used to completely close the drying tank 207 to prevent the staple fibers from flying away during stirring. After stirring is completed, the cover plate 306 is removed to facilitate the release of water vapor.

[0042] Specifically, the outer edge of the base 201 is fixedly connected with an installation box 202 corresponding to the drying tank 207. The driving mechanism 6 includes a horizontal linear slide 301 installed in the installation box 202, and a motor box 302 is fixedly connected to the slide seat 1 of the horizontal linear slide 301, and the output shaft of the motor box 302 is connected to the stirring rod 303. The base 201 is provided with a stirring rod through hole for inserting the stirring rod 303 into the drying tank 207. The cross-sectional shape of the stirring rod through hole is adapted to the cross-sectional shape of the stirring rod 303. When the stirring rod 303 does not extend into the drying tank 207, the stirring rod 303 will close the stirring rod through hole, thereby preventing short fibers from entering the installation box 202.

[0043] The driving mechanism 3 includes a horizontal linear slide 2 305 installed in the installation box 202, and the slide seat 2 of the horizontal linear slide 2 305 is connected to the mesh plate 307. The driving mechanism 7 includes a horizontal linear slide 3 304 installed in the installation box 202, and the slide seat 3 of the horizontal linear slide 304 is connected to the cover plate 306.

[0044] Embodiment 4

[0045] Furthermore, in this embodiment, a second electric heating wire is provided at the bottom of the receiving tank 206. When the lever 110 pushes the wet staple fibers into the drying tank 207, the second electric heating wire can be powered on to preheat the staple fibers. The second electric heating wire can restore the receiving tank 206 to a dry state, thereby preventing the dried staple fibers from becoming wet again when they are pushed out of the outlet 205 due to the residual moisture in the receiving tank 206.

[0046] Embodiment 5

[0047] Furthermore, in this embodiment, a horizontal linear slide 4 109 is provided below the outlet 205, and a collection frame 1 and a collection frame 2 are provided on the slide seat 4 of the horizontal linear slide 4 109. When the drying tank 207 is filled with wet staple fibers, there may still be some wet staple fibers in the receiving tank 206. At this time, the collection frame 1 is aligned with the outlet 205, so that this part of the wet staple fibers can be pushed out from the outlet 205 and fall into the collection frame 1. When the staple fibers need to be pushed out of the outlet 205 after being dried, the collection frame 2 is aligned with the outlet 205, so that the dry staple fibers can enter the collection frame 2.
