Description

Technical Field

[0001] This utility model belongs to the field of textile equipment technology, and in particular relates to a drying rack for chenille yarn production. Background Technology

[0002] Chenille yarn, also known as corduroy, is a new type of fancy yarn. It is made by twisting two strands of yarn into a core and sandwiching the downy yarn in the middle. It is mainly used to produce sofa covers, bedspreads, blankets, tablecloths and other products. A large number of textile equipment are used in the production process of chenille yarn. Among them, the drying rack is one of the most common textile equipment. The drying rack is used to dry the chenille yarn during the production process.

[0003] A document with publication number CN113566516A discloses a drying rack for polyester spinning production, including a receiving plate with support rods at each of the four corners. A yarn drying assembly is located above the receiving plate. The motor output extends through the left wall of the equipment box and is connected to a rotating shaft. A cam is sleeved on the outer wall of the middle part of the rotating shaft. A suction assembly is located behind the cam, and a transmission assembly is located in front of the cam. A fan blade is sleeved on the outer wall of the right end of the rotating shaft. Multiple guide plates are arranged in a linear structure inside the right side of the equipment box.

[0004] However, it still has the following drawbacks in practical use:

[0005] The aforementioned drying rack includes a yarn-drying assembly comprising multiple connecting rods arranged symmetrically in a linear structure. A yarn-drying tube is hinged between two adjacent connecting rods. The connecting rods near the left and right sides are connected and fixed to the inner walls of the support rods on both sides via hinge seats. A pressure plate is provided on the top surface of the yarn-drying tube, and the rear end of the pressure plate is connected and fixed to the rear end of the yarn-drying tube via bolts. The yarn-drying tube is used to dry chenille yarn. However, during use, due to the variety of chenille yarn lengths, and the fixed installation height of the yarn-drying tube in the aforementioned drying rack, it can only dry one type of chenille yarn. The current method of air-drying chenille yarn of various lengths has limited applicability and poor practicality. The aforementioned drying racks have support rods at the four corners of the receiving plate, a yarn-drying assembly above the receiving plate, and an equipment box on the upper left side of the receiving plate. The yarn-drying assembly hangs the chenille yarn for drying, and the equipment box uses electric heating wires and fan blades to air-dry the yarn. However, it lacks a structure for squeezing and dehydrating the chenille yarn, resulting in poor drying efficiency due to the high moisture content of the yarn. Therefore, we provide a drying rack for chenille yarn production to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a drying rack for chenille yarn production. The upper mounting frame is raised and lowered relative to the lower mounting frame by a screw, thereby adjusting the longitudinal spacing between the longitudinal bars. This solves the problem that it is not convenient to dry chenille yarn of different lengths. At the same time, the mounting frame and the extrusion roller are raised and lowered by an electric push rod, and the chenille yarn is squeezed and dehydrated by the extrusion roller, which solves the problem of poor drying efficiency in the existing process.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model is a drying rack for chenille yarn production, including support columns located around the perimeter, a yarn drying assembly arranged below the adjacent support columns, a top plate fixedly connected to the top of the support columns, and multiple sets of extrusion assemblies arranged on the top plate.

[0009] The yarn drying assembly includes a lower mounting frame fixedly connected below the adjacent support columns, an upper mounting frame movably connected above the lower mounting frame, multiple longitudinal rods fixedly connected at equal intervals along the inner sides of both the lower and upper mounting frames, a lead screw rotatably connected around the top of the lower mounting frame, the top of the lead screw rotatably passing through the top plate and fitted with a first bevel gear, and the upper mounting frame threaded around the lead screw.

[0010] The extrusion assembly includes U-shaped plates fixedly connected to the top plate at equal intervals along the transverse direction. Mounting plates are welded to the vertical support arms of the U-shaped plates. Electric push rods are fixedly connected to the upper surface of the mounting plates. The piston shafts of the electric push rods are fixedly connected to mounting frames. Moving blocks are movably connected to both sides inside the mounting frames. Extrusion rollers are rotatably connected between adjacent moving blocks.

[0011] A further feature of this invention is that: each of the outer walls of the support column near the upper mounting frame has a vertically formed groove; the front and rear ends of the outer walls on both sides of the upper mounting frame are welded with sliders; and the free ends of the sliders are movably connected to the inside of the groove.

[0012] A further feature of this invention is that a water tray is fixedly connected to the bottom end of the support column.

[0013] The present invention is further configured such that: the top of the horizontal support arm of the lower mounting bracket and the upper mounting bracket are provided with multiple threaded holes at equal intervals along the horizontal direction; a U-shaped frame is fitted on the horizontal support arm of the lower mounting bracket and the upper mounting bracket; a fastening bolt is threaded through the top of the U-shaped frame; the bottom end of the fastening bolt is threaded into the inside of the threaded hole; and both ends of the longitudinal rod are welded to the vertical support arm of the U-shaped frame.

[0014] A further feature of this invention is that the front and rear ends of the upper surface of the top plate are rotatably connected to a drive rod via a first bearing seat, and a second bevel gear is sleeved on both sides of the outer wall of the drive rod, with the second bevel gear meshing with one side of the first bevel gear.

[0015] A further feature of this invention is that both ends of the drive rod rotatably pass through the first bearing seat and are fixedly connected to handwheels, and a synchronous pulley is sleeved at the center of the outer wall of the drive rod, with the synchronous pulleys connected by a V-belt drive.

[0016] A further feature of this invention is that grooves are provided on both sides of the top and bottom of the mounting frame, and protrusions are welded to the top and bottom of the movable block, with the free ends of the protrusions being movably connected inside the grooves.

[0017] A further feature of this invention is that a sleeve rod is rotatably connected to the bottom center of the mounting frame via a second bearing seat, and inner rods are threaded onto both sides of the sleeve rod. A connecting plate is welded to the bottom of the protrusion located below the moving block, and one end of the inner rod located on the outside of the sleeve rod is fixedly connected to the outer wall of one side of the connecting plate.

[0018] This utility model has the following beneficial effects:

[0019] This invention features a yarn-drying assembly. A rotating drive rod, via a second bevel gear, drives a first bevel gear, which in turn drives a lead screw. The threaded connection between the lead screw and the upper mounting frame causes the upper mounting frame to rise and fall relative to the lower mounting frame. When the upper mounting frame reaches a designated position, both ends of the chenille yarn are secured to the longitudinal rods inside the lower and upper mounting frames, thus fixing the yarn. Natural wind or a fan is then used to air-dry the yarn, facilitating the drying of chenille yarn of different lengths. This invention is widely applicable and highly practical. The invention also includes a compression assembly. First, the spacing between the compression rollers is adjusted according to the thickness of the chenille yarn, ensuring the rollers press against both sides of the yarn. Then, an electric push rod is activated. Its piston shaft drives the mounting frame and compression rollers to rise and fall, further squeezing and dehydrating the chenille yarn, thus reducing its moisture content and improving drying efficiency. (See attached drawings.)

Detailed Implementation

[0032] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1

[0034] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, this is the first embodiment of the present invention. This embodiment provides a drying rack for chenille yarn production, including support columns 1 located around the perimeter. A top plate 2 is fixedly connected to the top of the support column 1, and a water tray 3 is fixedly connected to the bottom of the support column 1. A yarn drying assembly 4 is arranged below the adjacent support columns 1. The yarn drying assembly 4 includes a lower mounting frame 401, an upper mounting frame 402, longitudinal rods 403, and a screw 404. The screw 404 drives the upper mounting frame 402 to rise and fall relative to the lower mounting frame 401, thereby adjusting the longitudinal spacing between the longitudinal rods 403, which solves the problem of the existing method of drying chenille yarn of different lengths.

[0035] Specifically, the lower mounting bracket 401 is fixedly connected below the adjacent support columns 1. The upper mounting bracket 402 is movably connected above the lower mounting bracket 401. Multiple longitudinal rods 403 are fixedly connected at equal intervals along the transverse direction on the inner sides of both the lower mounting bracket 401 and the upper mounting bracket 402. Screws 404 are rotatably connected to the top of the lower mounting bracket 401. The top end of the screw 404 rotatably passes through the top plate 2 and is fitted with a first bevel gear 404a. The upper mounting bracket 402 is threaded onto the screw 404. The lower mounting bracket 401 and the upper mounting bracket 402 are used to install the longitudinal rods 403. The longitudinal rods 403 are used to bind the two ends of the chenille yarn. The screws 404 are used to drive the upper mounting bracket 402 to rise and fall relative to the lower mounting bracket 401, thereby adjusting the longitudinal spacing between the longitudinal rods 403. The first bevel gear 404a is used to drive the screw 404 to rotate.

[0036] Furthermore, each of the outer walls of the support column 1 near the upper mounting bracket 402 is provided with a vertical groove 101, and the front and rear ends of both outer walls of the upper mounting bracket 402 are welded with sliders 402a, and the free ends of the sliders 402a are movably connected to the inside of the groove 101.

[0037] The top of the horizontal support arm of the lower mounting bracket 401 and the upper mounting bracket 402 are provided with multiple threaded holes 402b at equal intervals along the horizontal direction. A U-shaped frame 403a is fitted on the horizontal support arm of the lower mounting bracket 401 and the upper mounting bracket 402. The top of the U-shaped frame 403a is threaded through with fastening bolts 403b. The bottom end of the fastening bolts 403b is threaded into the inside of the threaded hole 402b. Both ends of the longitudinal rod 403 are welded to the vertical support arm of the U-shaped frame 403a.

[0038] The front and rear ends of the upper surface of the top plate 2 are rotatably connected to the drive rod 405 through the first bearing seat 405a. The outer walls of the drive rod 405 are fitted with the second bevel gear 405b on both sides. The second bevel gear 405b are meshed with one side of the first bevel gear 404a.

[0039] Both ends of the drive rod 405 rotate through the first bearing seat 405a and are fixedly connected to a handwheel 405c. A synchronous pulley 405d is sleeved at the center of the outer wall of the drive rod 405, and the synchronous pulleys 405d are connected by a V-belt 405e.

[0040] The operation process of this embodiment is as follows: First, adjust the longitudinal distance between the lower mounting frame 401 and the upper mounting frame 402 according to the length of the chenille yarn. Rotate the handwheel 405c, which drives the drive rod 405 to rotate synchronously. Under the transmission connection between the synchronous wheel 405d and the V-belt 405e, the two drive rods 405 rotate synchronously. The drive rod 405 drives the first bevel gear 404a to rotate through the second bevel gear 405b. The first bevel gear 404a drives the lead screw 404 to rotate. Under the threaded connection between the lead screw 404 and the upper mounting frame 402, the upper mounting frame 402 moves up and down relative to the lower mounting frame 401. When the upper mounting frame 402 moves to the designated position, the two ends of the chenille yarn are tied to the longitudinal rods 403 inside the lower mounting frame 401 and the upper mounting frame 402 respectively, thus fixing the chenille yarn. The chenille yarn is then dried by natural wind or a fan.

[0041] Example 2

[0042] Please see Figure 1 , Figure 7 , Figure 8 and Figure 9As shown, this is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs from the previous embodiment in that: multiple sets of extrusion components 5 are provided on the top plate 2. The extrusion components 5 include a U-shaped plate 501, an electric push rod 502, a mounting frame 503, a moving block 504, and an extrusion roller 505. The electric push rod 502 drives the mounting frame 503 and the extrusion roller 505 to rise and fall, and the extrusion roller 505 is used to extrude and dehydrate the chenille yarn, thus solving the problem of poor drying efficiency in the existing system.

[0043] Specifically, the U-shaped plate 501 is fixedly connected to the top plate 2 at equal intervals along the horizontal direction. Mounting plates 501a are welded to the vertical support arms of the U-shaped plate 501. Electric push rods 502 are fixedly connected to the upper surface of each mounting plate 501a. Mounting frames 503 are fixedly connected to the piston shafts of the electric push rods 502. Moving blocks 504 are movably connected to both sides of the interior of the mounting frames 503. Extrusion rollers 505 are rotatably connected between adjacent moving blocks 504. The U-shaped plate 501 is used to hold the electric push rods 502 and other structures... Mounted on top plate 2, mounting plate 501a is used to mount electric push rod 502 on U-shaped plate 501. The piston shaft of electric push rod 502 is multi-sectioned. Electric push rod 502 is used to drive mounting frame 503 to lift and lower. Mounting frame 503 and moving block 504 are used to mount extrusion roller 505 and adjust the spacing between extrusion rollers 505 to facilitate the extrusion of chenille yarn of different diameters. Extrusion roller 505 is used to extrude and dehydrate chenille yarn.

[0044] Furthermore, grooves 503a are provided on both sides of the top and bottom of the mounting frame 503, and protrusions 504a are welded to the top and bottom of the moving block 504, with the free ends of the protrusions 504a being movably connected inside the grooves 503a.

[0045] At the bottom center of the mounting frame 503, a sleeve rod 503c is rotatably connected via a second bearing seat 503b. Both sides of the sleeve rod 503c are threaded with inner rods 503d. A connecting plate 504b is welded to the bottom of the protrusion 504a located below the moving block 504. One end of the inner rod 503d located outside the sleeve rod 503c is fixedly connected to one side of the outer wall of the connecting plate 504b.

[0046] The rest of the structure is the same as in Example 1.

[0047] The operation process of this embodiment is as follows: First, adjust the spacing between the compression rollers 505 according to the thickness of the chenille yarn. Rotate the sleeve rod 503c, which drives the connecting plate 504b to move in opposite directions or away from each other through the inner rod 503d. This causes the connecting plate 504b to drive the moving block 504 to move in opposite directions or away from each other, thereby adjusting the spacing between adjacent compression rollers 505 so that the compression rollers 505 squeeze the chenille yarn on both sides. Then, start the electric push rod 502. After the electric push rod 502 is started, its piston shaft drives the mounting frame 503 and the compression rollers 505 to rise and fall. The compression rollers 505 squeeze and dehydrate the chenille yarn, thereby reducing the moisture content of the chenille yarn and improving its drying efficiency.
