Description

TECHNICAL FIELD

[0001] The utility model relates to nylon chip production technical field, especially a kind of nylon chip quick drying device. BACKGROUND

[0002] Nylon chip is the granular product obtained by cutting method due to its low melt strength in nylon production.Polyamide (PA for short) is the commercial name of polyamide fiber, also known as nylon.The basic composition of its English name is aliphatic polyamide connected by amide bond--[NHCO]--.It is an important synthetic fiber.Nylon chip can only be cut underwater or air-cooled, and the water attached to it needs to be removed after underwater cutting.

[0003] At present, the existing drying equipment usually adopts the structure design of fixed containing box combined with hot air circulation system.The specific working process is as follows: the nylon chips are stacked in the containing box, and high-temperature airflow is blown by the hot air device at the bottom or side to dry.However, the nylon chips are naturally stacked in the static containing box under the action of gravity, and the wind preferentially passes through the upper space with smaller resistance, resulting in poor drying efficiency in the middle of material layer, poor drying uniformity and low drying efficiency. UTILITY MODEL CONTENT

[0004] In order to solve the above problems, the utility model provides a kind of nylon chip quick drying device.

[0005] The above technical purpose of the utility model is realized by the following technical scheme: a kind of nylon chip quick drying device, including drying box, the drying box is provided with drying assembly, the drying box top is provided with inlet pipe, bottom is provided with discharge pipe, the drying box top is provided with four rectangular array arrangement's sliding hole, sliding hole is vertically slidably provided with slide bar, four The lower end of slide bar is commonly provided with an open-top containing box, four The upper end of slide bar is commonly provided with an X-shaped connecting plate, the drying box top is provided with two vertical plates, two The rotating shaft is rotatably arranged between vertical plate, the rotating shaft is fixedly provided with cam, the cam wheel surface and connecting plate bottom surface contact, the drying box top surface is horizontally provided with drive motor, the output shaft of drive motor and rotating shaft end part are connected.

[0006] By adopting the above technical scheme, the drying box, the drying assembly, the containing box, the connecting plate, the cam and the driving motor are arranged, the polyamide chip is poured into the feeding pipe, and the polyamide chip falls into the containing box. Then the drying assembly blows out hot air, the hot air blows towards the polyamide chip and then blows out from the feeding pipe and the discharging pipe, taking away the moisture of the polyamide chip and drying the polyamide chip. The driving motor drives the rotating shaft to rotate, drives the cam to rotate, when the protruding part of the cam contacts the bottom surface of the connecting plate, the connecting plate is lifted upwards, four sliding rods are lifted, and the containing box is lifted, when the protruding part of the cam is separated from the bottom surface of the connecting plate, the connecting plate is lowered, the sliding rods and the containing box are lowered, and the containing box reciprocates up and down, so that the polyamide chip continuously tumbles and disperses in the hot air environment. This dynamic drying method effectively prevents the polyamide chip from piling up, ensures that the hot air fully contacts each polyamide chip, and significantly improves the drying uniformity and drying efficiency.

[0007] Further, the containing box comprises a frame plate and a bottom plate connected by a hinge shaft, a plurality of air holes are formed in the bottom plate, arc-shaped plates are arranged on both sides of the frame plate, arc-shaped grooves are formed in the arc-shaped plates, threaded rods are spirally arranged on both sides of the bottom plate, and the threaded rods pass through the corresponding arc-shaped grooves and are provided with handles.

[0008] By adopting the above technical scheme, the bottom plate contacts the bottom of the frame plate in the initial state, and the handle abuts against the arc-shaped plate. When the polyamide chip in the containing box needs to be taken out after drying is completed, the handle is rotated to move away from the arc-shaped plate, then the bottom plate is rotated to make the threaded rod contact the lower groove wall of the arc-shaped groove, then the handle is rotated to drive the threaded rod to rotate, so that the handle moves to contact the arc-shaped plate, and the positions of the threaded rod and the bottom plate are fixed. Then the rotating shaft and the cam are rotated to drive the containing box to reciprocate up and down, and the polyamide chip on the bottom plate is shaken and falls down and is discharged from the discharging pipe.

[0009] Further, the arc-shaped grooves are provided with circular fixing grooves at both ends, and the threaded rods are provided with circular blocks at the ends, and the handles are connected with the circular blocks.

[0010] By adopting the above technical scheme, the fixing grooves and the circular blocks are arranged, the circular block is located in the upper fixing groove in the initial state, and the circular block is located in the lower fixing groove when the polyamide chip in the containing box needs to be taken out, so that the fixing effect of the threaded rod and the bottom plate is better.

[0011] Further, a vertical column is vertically arranged in the middle of the top surface of the connecting plate, two vertical rods are arranged at intervals on the top of the drying box, a top plate is commonly arranged at the upper ends of the two vertical rods, a guide hole is formed in the top plate, the guide hole is slidably connected with the vertical column, and a compression spring is sleeved on the column between the top plate and the connecting plate.

[0012] By adopting the above technical solution, a column, a top plate, and a compression spring are set up. When the cam protrusion contacts the bottom surface of the connecting plate and pushes the connecting plate upward, the compression spring is compressed. When the cam protrusion separates from the bottom surface of the connecting plate, the compression spring loses its restraint and pushes the connecting plate downward rapidly under the action of elasticity, which makes the oscillation effect of the container better.

[0013] Furthermore, a door is hinged to one side of the drying oven, and the door is U-shaped. Both arc-shaped plates are located within the U-shaped area of ​​the door, and a baffle is provided at the bottom of the drying oven near the door.

[0014] By adopting the above technical solution, a door and baffle are installed, and the handle can be turned by opening the door. The baffle is located at the door of the drying oven and serves to block the nylon chips from rushing out of the drying oven due to the tilt of the bottom plate.

[0015] Furthermore, the drying assembly includes a conveying pipe disposed on the top surface of the drying chamber, with four L-shaped pipes connected to the conveying pipe. One end of the conveying pipe is closed, and the other end passes through the drying chamber and is equipped with a heating pipe. Several heating wires are disposed inside the heating pipe. A blower is disposed on the outer wall of the drying chamber, and the air outlet of the blower is connected to the end of the heating pipe away from the conveying pipe.

[0016] By adopting the above technical solution, a conveying pipe, an L-shaped pipe, a heating pipe, and a heating wire are set up. A blower blows air into the heating pipe, and the heating wire heats the air. The heated air then passes through the conveying pipe and the L-shaped pipe to reach the drying chamber.

[0017] Furthermore, a fixing pipe is provided at the top of the drying oven corresponding to the through hole, and the slide rod is slidably connected to the fixing pipe.

[0018] In summary, this utility model has the following beneficial effects: This application includes a drying chamber, a drying assembly, a receiving box, a connecting plate, a cam, and a drive motor. Nylon chips are poured into the feed pipe and fall into the receiving box. The drying assembly then blows hot air onto the nylon chips, which then exits through the feed and discharge pipes, removing moisture and drying the chips. The drive motor drives the rotating shaft to rotate, causing the cam to rotate. When the cam's protruding part contacts the bottom surface of the connecting plate, it lifts the connecting plate upwards, causing the four sliding rods to rise, thus lifting the receiving box. When the cam's protruding part separates from the bottom surface of the connecting plate, the connecting plate descends, causing the sliding rods and the receiving box to descend. The receiving box oscillates up and down, causing the nylon chips to continuously tumble and disperse in the hot air environment. This dynamic drying method effectively prevents the accumulation of nylon chips and ensures that the hot air fully contacts each nylon chip, thereby significantly improving drying uniformity and efficiency.

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] like Figures 1-7As shown in the illustration, this application discloses a rapid drying device for nylon chips, including a drying chamber 10, a drying assembly 40, a cam 15, and a drive motor 16. The drying assembly 40 is mounted on the drying chamber 10 and is used to blow hot air into the drying chamber 10. The drying chamber 10 has a feed pipe 11 at the top and a discharge pipe 12 at the bottom. Nylon chips are poured into the feed pipe 11 and fall into the receiving box 50. Then, the drying assembly 40 blows out hot air, which is directed at the nylon chips. The moisture on the nylon chips is evaporated, and then blown out from the feed pipe 11 and the discharge pipe 12, thus removing the moisture from the nylon chips and drying them. The top of the drying oven 10 has four sliding holes arranged in a rectangular array. A sliding rod 20 is vertically slidably installed in the sliding holes. The lower end of the four sliding rods 20 is provided with a receiving box 50 with a top opening. The upper end of the four sliding rods 20 is provided with an X-shaped connecting plate 21. Two upright plates 13 are spaced apart on the top of the drying oven 10. A rotating shaft 14 is rotatably installed between the two upright plates 13. A cam 15 is fixedly sleeved on the rotating shaft 14. The wheel surface of the cam 15 contacts the bottom surface of the connecting plate 21. A drive motor 16 is horizontally installed on the top surface of the drying oven 10. The output shaft of the drive motor 16 is connected to the end of the rotating shaft 14. The drive motor 16 drives the rotating shaft 14 to rotate, which in turn drives the cam 15 to rotate. When the protruding part of the cam 15 contacts the bottom surface of the connecting plate 21, it lifts the connecting plate 21 upward, causing the four sliding rods 20 to rise, thereby lifting the receiving box 50. When the protruding part of the cam 15 separates from the bottom surface of the connecting plate 21, the connecting plate 21 descends, causing the sliding rods 20 and the receiving box 50 to descend. The receiving box 50 oscillates up and down, causing the nylon chips to continuously tumble and disperse in the hot air environment. This dynamic drying method effectively prevents the accumulation of nylon chips and ensures that the hot air fully contacts each nylon chip, thereby significantly improving drying uniformity and drying efficiency.

[0029] Specifically, a fixed tube 19 is installed at the top of the drying chamber 10 corresponding to the through hole, and the slide rod 20 is slidably connected to the fixed tube 19 to further ensure the stability of the slide rod 20. An inclined plate is installed at the top of the drying chamber 10 at the feed pipe 11 to ensure that the nylon chips entering from the feed pipe 11 can fall into the receiving box 50. The bottom of the drying chamber 10 is funnel-shaped. A door 17 is hinged on one side of the drying chamber 10, and a door lock is installed on the door 17. The door 17 is U-shaped. The drying assembly 40 includes a conveying pipe 41 installed on the top surface of the drying chamber 10. Four L-shaped pipes 42 are connected to the conveying pipe 41. One end of the conveying pipe 41 is closed, and the other end passes through the drying chamber 10 and is equipped with a heating pipe 43. Several heating wires 44 are installed in the heating pipe 43. The working principle of the heating wires 44 is mainly based on the thermal effect of electric current. That is, when the current passes through the resistive material, the electrical energy is converted into heat energy, thereby heating the material. A blower 45 is installed on the outer wall of the drying oven 10. The air outlet of the blower 45 is connected to the end of the heating tube 43 away from the conveying tube 41. The blower 45 blows air into the heating tube 43, and the heating wire 44 heats the air. The heated air reaches the drying oven 10 through the conveying tube 41 and the L-shaped tube 42.

[0030] During setup, the receiving box 50 includes a frame plate 51 and a base plate 52 hinged to the frame plate 51 via a hinge shaft. The frame plate 51 is relatively high to prevent the nylon chips inside the receiving box 50 from jumping out when it vibrates. The base plate 52 has several ventilation holes 53. Arc-shaped plates 54 are provided on both sides of the frame plate 51, and arc-shaped grooves 55 are formed on the arc-shaped plates 54. The centers of the arcs of the arc-shaped plates 54 and the arc-shaped grooves 55 coincide with the axis of the hinge shaft. Threaded rods 56 are spirally arranged on both sides of the base plate 52. The threaded rods 56 are horizontally arranged, pass through the corresponding arc-shaped grooves 55, and have handles 57. In the initial state, the base plate 52 is in contact with the bottom of the frame plate 51, and the handles 57 abut against the arc-shaped plates 54. When the drying process is complete and the nylon chips need to be removed from the receiving box 50, rotate the handle 57 to move it away from the arc-shaped plate 54. Then rotate the base plate 52 so that the threaded rod 56 contacts the lower wall of the arc-shaped groove 55. Rotate the handle 57 again to rotate the threaded rod 56, causing the handle 57 to move and contact the arc-shaped plate 54, thus fixing the positions of the threaded rod 56 and the base plate 52. Subsequently, the rotating shaft 14 and cam 15 rotate, causing the receiving box 50 to oscillate up and down. The nylon chips on the base plate 52 are shaken off and discharged from the discharge pipe 12. The arc-shaped groove 55 has circular fixing grooves 58 at both ends, and the threaded rod 56 has a circular block 59 at its end. The handle 57 is connected to the circular block 59. Initially, the circular block 59 is located in the upper fixing groove 58. When the nylon chips need to be removed from the receiving box 50, the circular block 59 is located in the lower fixing groove 58, resulting in better fixation of the threaded rod 56 and the base plate 52. Both curved plates 54 are located within the U-shaped area of ​​the door 17. A baffle 18 is installed at the bottom of the drying oven 10 at the door 17. The handle 57 can be turned by opening the door 17. The baffle 18 is located at the door 17 of the drying oven 10 and serves to block the nylon chips from rushing out of the drying oven 10 due to the tilt of the bottom plate 52.

[0031] In the specific setup, a column 22 is vertically installed in the middle of the top surface of the connecting plate 21. Two vertical rods 30 are spaced apart on the top of the drying box 10. A top plate 31 is installed at the upper end of the two vertical rods 30. A guide hole is opened on the top plate 31, and the guide hole is slidably connected to the column 22. A compression spring 32 is fitted on the column 22 located between the top plate 31 and the connecting plate 21. The upper end of the compression spring 32 is connected to the top plate 31, and the lower end is connected to the connecting plate 21. When the protruding part of the cam 15 contacts the bottom surface of the connecting plate 21 and pushes the connecting plate 21 upward, the compression spring 32 is compressed. When the protruding part of the cam 15 separates from the bottom surface of the connecting plate 21, the compression spring 32 loses its restraint and pushes the connecting plate 21 down rapidly under the action of elastic force, so that the oscillation effect of the receiving box 50 is better.

[0032] The operating principle of the nylon chip rapid drying device in this embodiment is as follows:

[0033] Nylon chips are poured into the feed pipe 11 and fall into the receiving box 50. Then, the blower 45 is turned on to blow air into the heating pipe 43. The heating wire 44 heats the air. The heated air passes through the conveying pipe 41 and the L-shaped pipe 42 to reach the drying chamber 10. Then, it is blown out from the feed pipe 11 and the discharge pipe 12, taking away the moisture from the nylon chips and drying them.

[0034] Simultaneously, the drive motor 16 is activated to drive the rotating shaft 14 to rotate, which in turn drives the cam 15 to rotate. When the protruding part of the cam 15 contacts the bottom surface of the connecting plate 21, it pushes the connecting plate 21 upward, causing the four slide rods 20 to rise, thereby causing the receiving box 50 to rise, and the compression spring 32 is compressed. When the protruding part of the cam 15 separates from the bottom surface of the connecting plate 21, the compression spring 32 loses its restraint and, under the action of elastic force, pushes the connecting plate 21 to descend rapidly, causing the slide rods 20 and the receiving box 50 to descend. The receiving box 50 oscillates up and down, causing the nylon chips to continuously tumble and disperse in the hot air environment.

[0035] After drying, the staff, wearing heat-resistant gloves, open the chamber door 17 and then turn the two handles 57, moving the threaded rod 56 and the round block 59. The round block 59 separates from the upper fixing groove 58. Then, the bottom plate 52 is rotated until the round block 59 aligns with the lower one. The handle 57 is then turned again, moving the threaded rod 56 and the round block 59 so that the round block 59 enters the lower fixing groove 58. Next, the chamber door 17 is closed, and the drive motor 16 drives the receiving box 50 to vibrate up and down. The nylon chips on the bottom plate 52 are vibrated and fall off, exiting from the discharge pipe 12.

[0036] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
