Description

Technical Field

[0001] This utility model belongs to the field of nylon chip processing technology, and specifically relates to a nylon chip drying device. Background Technology

[0002] Nylon chips are sheet-like granulated products obtained by pelletizing nylon chips due to their low melt strength during nylon production. They are also commonly known as nylon chips or polyamide chips. They are the basic raw material for manufacturing synthetic fibers—nylon. They are high molecular polymers composed of a series of repeating units linked by amide bonds. Industrially, they are mainly used to produce various types of nylon fibers, engineering plastics, and films. Drying equipment is required to dry nylon chips during processing.

[0003] Existing nylon chip drying devices work by pouring the nylon chips to be dried into the device, then rotating a stirring shaft to drive a stirring paddle, which rapidly tumbles the nylon chips. During this tumbling process, hot air is blown onto the nylon chips to achieve rapid drying. However, in actual use, the tumbling structure is relatively simple, and the large quantity of nylon chips to be dried at one time makes it difficult for some chips to fully contact the hot air, resulting in poor drying efficiency. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a nylon chip drying device. By rotating multiple stirring paddles and moving the drying cylinder up and down during the reciprocating rotation, the tumbling force on the nylon chips inside the drying cylinder is increased, so as to better heat and dry the nylon chips.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a nylon chip drying device, including a drying tower, a rotating seat fixedly installed inside the drying tower, a spline sleeve rotatably installed inside the rotating seat, a spline cylinder slidably installed inside the spline sleeve, a drying cylinder fixedly installed inside the spline cylinder, a heating mechanism installed on the outside of the drying tower, the heating mechanism heating the inside of the drying cylinder, a driving mechanism installed between the drying tower and the drying cylinder, the driving mechanism driving the movement of the drying cylinder; a fixing ring at the top of the inside of the drying tower, the fixing ring being slidably connected to the upper side of the drying cylinder; a frame installed at the lower end of the outside of the drying tower, multiple mounting holes opened on the lower side of the frame, and a feed pipe installed on the upper side of the drying tower.

[0006] As a further improvement of this utility model, the drive mechanism includes multiple mounting seats fixedly installed on the outside of the drying cylinder. Multiple rotating shafts are rotatably installed on the outside of each mounting seat. Conical wheels are fixedly sleeved on the outer arc surface of each rotating shaft. Multiple support plates are installed inside the drying tower. Guide rails are installed on the upper surface of each support plate. The conical wheels are respectively installed in conjunction with the adjacent guide rails. A bevel gear ring is fixedly sleeved on the outside of the spline sleeve. A bevel gear is rotatably installed inside the drying tower through a rotating shaft. The bevel gear meshes with the bevel gear ring. A second motor is installed on the outside of the drying tower. The output shaft of the second motor is fixed to the rotating shaft through a coupling.

[0007] As a further improvement of this utility model, the heating mechanism includes a hot air box disposed on the outside of the drying tower. The hot air box is connected to the drying tower through an air supply pipe. A dustproof net is disposed on the outside of the hot air box, and multiple hot air blowers are disposed inside the hot air box.

[0008] As a further improvement of this utility model, a stirring shaft is rotatably installed at the top center of the drying tower, and multiple stirring paddles are installed on the outside of the stirring shaft. The output shaft of motor one is fixed to the stirring shaft by a coupling on the upper surface of the drying tower.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] Firstly, the output shaft of motor one drives the stirring shaft connected to it to rotate, which in turn causes the stirring shaft to drive the multiple stirring paddles set on its outer arc surface to rotate. The output shaft of motor two drives the rotating shaft connected to it to rotate back and forth, so that the spline sleeve drives the drying cylinder to rotate back and forth through the spline cylinder. The rotation of the stirring paddles and the rotation of the drying cylinder are used to turn the nylon chips over, so as to achieve efficient drying.

[0011] Secondly, during the rotation of the drying cylinder, the rotating shaft driven by the drying cylinder rotates around the vertical center of the drying cylinder. During the movement of the conical wheel, the conical wheel moves on the guide rail. Through the cooperation between the uneven annular guide rail and the conical wheel, the drying cylinder moves up and down repeatedly during the forward and reverse rotation, which can effectively increase the turning effect on the nylon chips.

[0012] Thirdly, the stirring shaft drives multiple stirring paddles on its outer arc surface to rotate, which rapidly tumbles the nylon chips inside the drying cylinder. The up-and-down movement of the drying cylinder during its reciprocating rotation increases the tumbling force on the nylon chips inside, thus facilitating better heating and drying of the nylon chips.

[0013] Fourth, by using external tools to tighten the bolts passing through the mounting holes to fix the frame to the ground, the position of the drying tower can be easily prevented from moving during daily use. Attached Figure Description

[0020] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0021] like Figure 2 , 4 As shown, the drying tower includes a drying tower 102. A rotating seat 201 is fixedly installed inside the drying tower 102. A spline sleeve 202 is rotatably installed inside the rotating seat 201. A spline cylinder 203 is slidably installed inside the spline sleeve 202. A drying cylinder 204 is fixedly installed inside the spline cylinder 203. A heating mechanism is installed on the outside of the drying tower 102 to heat the inside of the drying cylinder 204. A driving mechanism is also installed between the drying tower 102 and the drying cylinder 204 to drive the movement of the drying cylinder 204. A fixing ring 104 is located at the top of the inside of the drying tower 102 and is slidably connected to the upper side of the drying cylinder 204.

[0022] like Figure 2 , 3As shown, the drive mechanism includes multiple mounting seats 208 fixedly mounted on the outside of the drying cylinder 204. Multiple rotating shafts 209 are rotatably mounted on the outside of each mounting seat 208. Conical wheels 210 are fixedly sleeved on the outer arc surface of each rotating shaft 209. Multiple support plates 211 are provided inside the drying tower 102. Guide rails 212 are provided on the upper surface of each support plate 211. The conical wheels 210 are respectively installed in cooperation with the adjacent guide rails 212. A bevel gear ring 205 is fixedly sleeved on the outside of the spline sleeve 202. A bevel gear 206 is rotatably mounted inside the drying tower 102 via a rotating shaft. The bevel gear 206 meshes with the bevel gear ring 205. A second motor 207 is provided on the outside of the drying tower 102. The output shaft of the second motor 207 is fixed to the rotating shaft via a coupling.

[0023] like Figure 2 , 4 As shown, the heating mechanism includes a hot air box 107 located outside the drying tower 102. The hot air box 107 is connected to the drying tower 102 through an air duct 108. A dustproof net 110 is provided on the outside of the hot air box 107, and multiple hot air blowers 109 are provided inside the hot air box 107.

[0024] like Figure 2 , 4 As shown, a stirring shaft 105 is rotatably installed at the top center of the drying tower 102. Multiple stirring paddles 106 are installed on the outside of the stirring shaft 105. The output shaft of a motor 111 is fixed to the stirring shaft 105 via a coupling on the upper surface of the drying tower 102.

[0025] According to another embodiment of the present invention, such as Figure 1 , 2 As shown, a frame 101 is provided at the lower outer side of the drying tower 102, and multiple mounting holes are provided on the lower side of the frame 101. A feed pipe 103 is provided on the upper side of the drying tower 102.

[0026] In use, the output shaft of motor 111 drives the stirring shaft 105 connected to it to rotate, which in turn causes the stirring shaft 105 to drive the multiple stirring paddles 106 set on its outer arc surface to rotate.

[0027] The output shaft of motor 207 drives the rotating shaft connected to it to rotate back and forth, and then drives the spline sleeve 202 where the bevel gear 205 is located to rotate through the meshing relationship between the bevel gear 206 and the bevel ring 205, so that the spline sleeve 202 drives the drying cylinder 204 to rotate back and forth through the spline cylinder 203.

[0028] During the rotation of the drying cylinder 204, the rotating shaft 209 driven by the drying cylinder 204 rotates around the vertical center of the drying cylinder 204, causing the drying cylinder 204 to drive the conical wheel 210 to move back and forth around the vertical center of the drying cylinder 204 in an arc-shaped trajectory via the rotating shaft 209. During the movement of the conical wheel 210, the conical wheel 210 moves on the guide rail 212. Through the cooperation between the uneven annular guide rail 212 and the conical wheel 210, the drying cylinder 204 moves up and down back and forth during the back and forth rotation.

[0029] The hot air is drawn in by the hot air blower 109 and heated. The heated air enters the interior of the air duct 108 and is then transported into the interior of the drying cylinder 204 through the air duct 108 to heat the interior of the drying cylinder 204.

[0030] By using external tools to tighten the bolts passing through the mounting holes to fix the frame 101 to the ground, the position of the drying tower 102 can be effectively prevented from easily moving during daily use;

[0031] In use, the nylon chips to be dried are poured into the feed pipe 103, so that the nylon chips to be dried enter the drying cylinder 204 from the feed pipe 103. The stirring shaft 105 drives the multiple stirring paddles 106 set on its outer arc surface to rotate, which quickly turns the nylon chips inside the drying cylinder 204. The up and down movement of the drying cylinder 204 during the forward and reverse rotation increases the turning force of the nylon chips inside the drying cylinder 204, so as to better heat and dry the nylon chips.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it.
