Description

Technical Field

[0001] The invention relates to the technical field of material drying, and in particular to a layered material drying device and method. Background Art

[0002] Cheese yarn is the output of the winding process of the spinning mill in the textile industry. It is the tube yarn that falls from the spinning frame or twisting machine in the previous process. According to the requirements of the subsequent processes using yarn in weaving factories, knitting factories, towel factories, etc., the yarn length is lengthened and the defects and impurities on the yarn are removed. Then, the yarn is rewound on the bobbin layer by layer through a grooved drum or a rapidly reciprocating yarn guide hook on the winding machine. Therefore, it is usually called cheese yarn. In the production process, cheese yarn generally goes through the steps of dyeing, dehydration and drying, so a drying device is required to dry the cheese yarn.

[0003] The Chinese patent document with authorization announcement number CN109518384B discloses a radio frequency dryer for cheese yarn that can quickly discharge and unload materials. The radio frequency dryer for cheese yarn that can quickly discharge and unload materials realizes the rapid discharge and unloading of cheese yarn through the joint action of a motor, a driving wheel, a driven wheel, a belt, a first rotating shaft, a first bearing and a fixed block, thereby avoiding the workers from spending a long time on the placement process, and realizes the limitation of the cheese yarn, avoiding the collision and squeezing of multiple cheese yarns, thereby bringing great convenience to the workers.

[0004] However, the structural design of the above-mentioned related technology: the material at the edge is at the edge of the radiation source, resulting in that the material cannot be well penetrated during the drying process, so that the material cannot achieve an effective drying effect after being dried once, and other equipment or manual labor is required to pick out the ineffectively dried cheese yarns, and then put the picked cheese yarns into the drying device for re-drying, which not only makes the cheese yarn drying efficiency low, but also increases the labor cost.

[0005] Therefore, a layered material drying device and method are proposed to solve the above-mentioned problems. Summary of the invention

After the workpiece faces downward, the dried workpiece can cause short rack 3 to drive the rotating assembly to reverse, reset the support, and make the dried workpiece fall, while the undried workpiece continues to be dried.

[0008] Beneficial effect: the workpiece is placed on the supporting assembly, and then the driving assembly drives the supporting assembly into the drying chamber through the sliding mechanism to dry the workpiece. After the workpiece passes through the drying chamber, the adjusting mechanism drives the rotating assembly to rotate, and the rotating assembly drives the supporting member to extend the supporting cylinder through the turntable to block the top of the workpiece. Then the driving assembly continues to drive the sliding mechanism to move the workpiece downward. At this time, the dried workpiece can cause the adjusting mechanism to drive the rotating assembly to reverse, so that the supporting member is reset, thereby causing the dried workpiece to fall. The undried workpiece can prevent the adjusting mechanism from contacting the rotating assembly, so that the undried workpiece can continue to be dried, thereby achieving the effect of automatically picking out the undried workpiece, without the need to use other equipment or manual labor to pick out the undried workpiece, thereby improving the drying efficiency of the workpiece and reducing labor costs.

[0009] Preferably, the support assembly includes a fixed cylinder connected to the sliding mechanism and a tray elastically slidably connected along the vertical direction, the tray is rotatably connected to the rotating assembly, a plurality of through grooves are provided on the outer side of the top end of the tray, a support plate slidably connected in the through grooves is installed at the bottom end of the support cylinder, and the support plate is installed on the inner bottom wall of the fixed cylinder.

[0010] The effect is that the workpiece can be placed on the pallet, and after the workpiece is placed on the pallet, the pallet can adjust the position of the rotating assembly according to the weight of the workpiece to prevent the support member from extending out of the support tube when the workpiece just enters the drying chamber.

[0011] Preferably, the rotating assembly includes a rotating rod located inside the supporting tube, a rotating shaft inserted outside the rotating rod, and a gear 2 installed at the bottom end of the rotating shaft, the tray is rotationally connected to the outside of the rotating shaft, and the gear 2 is located at the bottom end of the fixed tube.

[0012] The effect is that the rotating disk can be driven to rotate through the rotating rod, so that the rotating disk drives the supporting member to extend or retract the supporting tube.

[0013] Preferably, a connecting tube is installed on the outer side of the rotating rod, the top end of the rotating shaft is located inside the connecting tube, two baffles arranged up and down with a distance therebetween are installed on the outer side of the top end of the rotating shaft, and the top end of the rotating rod is fixed to the turntable.

[0014] The effect is that, through the coordinated arrangement of the connecting tube and the baffle, the rotating shaft can be pulled downward after the workpiece falls onto the supporting member to adjust the position of the second gear.

[0015] Preferably, the fixing plate is fixed to the inner wall of the base, the thickness of the short rack two is greater than the thickness of the short rack one, and the short rack one, the short rack two and the plurality of short racks three can all mesh with the gear two.

[0016] Preferably, the sliding mechanism comprises two mounting plates connected to the driving assembly and two transmission wheels rotatably connected between the two mounting plates, two transmission wheels are provided with transmission members 2, and the fixing cylinder is connected to the transmission members 2.

[0017] Preferably, a connecting rod is installed at the bottom end of the transmission wheel 2, and the bottom end of the connecting rod passes through the mounting plate and extends to the outside of the mounting plate. A gear 1 is installed at the bottom end of the connecting rod, and long racks that can mesh with gear 1 are installed on both sides of the top of the fixed plate.

[0018] The effect is that, by providing the long rack, multiple workpieces can be driven to rotate around the second transmission member when the workpieces pass through the drying chamber, so as to continuously change the positions of the workpieces and enable the workpieces to be evenly heated.

[0019] The layered material drying method of the present invention utilizes the layered material drying device described above, and comprises the following steps: S1: Place the workpiece on the tray and put it on the outside of the support tube, and then the driving component drives the workpiece on the tray into the drying chamber; S2: During drying, gear 1 meshes with the long rack, gear 1 drives transmission member 2 on transmission wheel 2 to rotate through the connecting rod, and transmission member 2 drives multiple workpieces to reciprocate around the trajectory of transmission member 2. When gear 1 disengages from the long rack, the workpieces are reset; S3: After the workpiece moves out of the drying chamber, the second gear meshes with the second short rack, so that the support member extends out of the support cylinder, and then driven by the first transmission member, the workpiece rotates downward along the trajectory of the first transmission member; S4: The downward workpiece is driven by the support member to move down gear 2, and the completely dried workpiece drives gear 2 to mesh with short rack 3, so that the support member is reset, and the completely dried workpiece falls off, and the workpiece that is not completely dried is driven by the transmission member 1 for secondary drying.

[0020] Beneficial effect: After the workpiece is placed on the tray, the driving assembly drives the workpiece into the drying chamber. When the workpiece passes through the drying chamber, the long rack drives gear one to rotate, so that the workpiece moves back and forth around the trajectory of transmission member two, so that the workpiece is evenly heated. After the workpiece passes through the drying chamber, the short rack two drives gear two to rotate, so that the support member extends out of the support cylinder to block the top of the workpiece, and then the driving assembly continues to drive the workpiece to move downward. At this time, the dried workpiece can make the short rack three mesh with gear two to reset the support member, thereby causing the dried workpiece to fall. The undried workpiece can prevent gear two from meshing with the short rack three, thereby allowing the undried workpiece to continue to be dried.

[0021] By adopting the above technical scheme, the beneficial effects of the present invention are as follows: the workpiece is placed on the support assembly, and the driving assembly drives the support assembly to enter the drying chamber through the sliding mechanism to dry the workpiece. After the workpiece passes through the drying chamber, the adjusting mechanism drives the rotating assembly to rotate, and the rotating assembly drives the support member to extend the supporting cylinder through the turntable to block the top of the workpiece, and then the driving assembly continues to drive the sliding mechanism to move the workpiece downward. At this time, the dried workpiece can cause the adjusting mechanism to drive the rotating assembly to reverse, so that the support member is reset, thereby causing the dried workpiece to fall, and the undried workpiece continues to be dried, thereby achieving the effect of automatically picking out the undried workpiece, without the need to use other equipment or manual labor to pick out the undried workpiece, thereby improving the drying efficiency of the workpiece and reducing labor costs.

In this embodiment, a radio frequency dryer is provided in the drying chamber 20, and there are multiple drying chambers 20, which are sequentially connected and installed on the top of the base 10 for drying workpieces. The inner bottom wall of the base 10 is inclined, and a discharge port is provided on one side of the base 10 for discharging the dried workpieces. There are two driving assemblies 30, and the two driving assemblies 30 are respectively arranged on both sides of the inner wall of the base 10. There are multiple sliding mechanisms 40, and the multiple sliding mechanisms 40 are evenly distributed between the two driving assemblies 30. There are two groups of placing mechanisms 50 for placing workpieces, and each group of placing mechanisms 50 has multiple numbers, and the multiple placing mechanisms 50 are arranged on the sliding mechanism 40 at equal intervals along the width direction of the base 10. The adjusting mechanism 60 is installed on the inner wall of the base 10 for adjusting the position of the placing mechanism 50.

[0031] The workpiece is placed on the placement mechanism 50, and then the driving component 30 drives the placement mechanism 50 to enter the drying chamber 20 through the sliding mechanism 40 to dry the workpiece. When the workpiece passes through the drying chamber 20, the adjustment mechanism 60 drives the sliding mechanism 40 to operate, so that multiple placement mechanisms 50 move around the sliding mechanism 40 to continuously change the position of the workpiece to make the workpiece dried more evenly.

[0032] like Figure 1 to Figure 2 As shown, the driving assembly 30 includes a transmission member 32, a motor 33 and two transmission wheels 31. The two transmission wheels 31 are both rotatably connected to one side of the inner wall of the base 10, and there is a spacing between the two transmission wheels 31. The transmission member 32 is arranged on the outside of the two transmission wheels 31. In this embodiment, the transmission wheel 31 is a pulley and the transmission member 32 is a belt. In other embodiments, the transmission wheel 31 is a sprocket and the transmission member 32 is a chain. The motor 33 is installed on one side of the base 10, and the driving shaft of the motor 33 is fixed to one of the transmission wheels 31.

[0033] like Figures 1 to 3 As shown, the sliding mechanism 40 includes a transmission member 2 44, two mounting plates 41 and two transmission wheels 2 43. The two mounting plates 41 are arranged up and down and have a spacing, and a connecting column 42 is installed between the two mounting plates 41. The two transmission wheels 2 43 are both rotatably connected between the two mounting plates 41, the connecting column 42 is located between the two transmission wheels 2 43, and the transmission member 2 44 is arranged on the outside of the two transmission wheels 2 43. The transmission wheel 2 43 has the same structure as the transmission wheel 1 31, the transmission member 2 44 has the same structure as the transmission member 1 32, and the placement mechanism 50 is connected to the transmission member 2 44.

[0034] A connecting rod 45 is installed at the bottom end of the transmission wheel 2 43. The bottom end of the connecting rod 45 penetrates the mounting plate 41 and extends to the outside of the mounting plate 41. A gear 1 46 is installed at the bottom end of the connecting rod 45. The gear 1 46 can mesh with the adjustment mechanism 60. Connecting frames 47 are installed on both sides of the bottom of the mounting plate 41 below. The connecting frames 47 are U-shaped. The two connecting frames 47 are connected to the transmission members 1 32 on the two driving assemblies 30 through connecting blocks.

[0035] The motor 33 can drive the transmission member 32 to rotate through the transmission wheel 31, and the transmission member 32 can drive the mounting plate 41 to move around the trajectory of the transmission member 32. When the mounting plate 41 passes through the drying chamber 20, the gear 46 engages with the adjustment mechanism 60. At this time, the adjustment mechanism 60 drives the transmission wheel 43 on the connecting rod 45 to rotate through the gear 46, so as to drive the transmission member 44 to rotate. The transmission member 44 drives multiple placement mechanisms 50 to rotate around the trajectory of the transmission member 44, thereby continuously changing the position of the workpiece.

[0036] like Figures 1 to 4 As shown, the placement mechanism 50 includes a support assembly 51, a support cylinder 52, a rotation assembly 53 and a limit assembly 54. The support assembly 51 is arranged on the transmission member 2 44, the support cylinder 52 is arranged in the support assembly 51, the rotation assembly 53 is arranged inside the support cylinder 52, and the limit assembly 54 is arranged on the rotation assembly 53.

[0037] like Figure 3 to Figure 4As shown, the support assembly 51 includes a fixed cylinder 511 and a tray 512. The top of the fixed cylinder 511 has an opening, and a protrusion 516 is installed on the outer side of the fixed cylinder 511, and the protrusion 516 is connected to the transmission member 244. The tray 512 is slidably connected to the inside of the fixed cylinder 511, and a through hole 514 is opened in the middle of the top of the tray 512, and a plurality of through grooves 515 are opened on the outer side of the top of the tray 512 near the through hole 514. A plurality of elastic members 513 are installed at the bottom end of the tray 512, and the plurality of elastic members 513 are distributed in a circular array with the axis of the tray 512 as the center. In this embodiment, the elastic member 513 is a spring, and the elastic member 513 is an elastic sheet.

[0038] The rotation of the second transmission member 44 can drive the plurality of fixed cylinders 511 to move along the trajectory of the second transmission member 44 , so that the workpieces can exchange positions inside the drying chamber 20 , thereby improving the drying effect on the workpieces.

[0039] like Figure 4 As shown, a plurality of support plates 56 are installed at the bottom end of the support cylinder 52, and the plurality of support plates 56 are distributed in a circular array with the axis of the tray 512 as the center. The support plates 56 are installed on the inner bottom wall of the fixed cylinder 511, and the support plates 56 are slidably connected in the through groove 515.

[0040] When the workpiece is placed on the tray 512 , the workpiece is sleeved on the outside of the support tube 52 , and the tray 512 gradually moves downward under the pressure of the workpiece. At this time, the elastic member 513 is compressed, and the support plate 56 slides in the through groove 515 during the sliding process of the tray 512 .

[0041] Continue to refer Figure 4 As shown, a plurality of guide grooves 55 are formed at the top of the support tube 52 , and the plurality of guide grooves 55 are distributed in a circular array with the axis of the support tube 52 as the center.

[0042] like Figure 1 , Figures 4 to 5 As shown, the rotating assembly 53 includes a rotating rod 531, a rotating shaft 533 and a second gear 535. The rotating rod 531 is located above the inner part of the supporting cylinder 52, and the rotating shaft 533 is inserted outside the bottom end of the rotating rod 531. The bottom end of the rotating rod 531 is provided with an outer spline groove, and the top end of the rotating shaft 533 is provided with an inner spline groove adapted to the outer spline groove on the rotating rod 531. The outer side of the rotating shaft 533 is rotatably connected with the inner wall of the through hole 514, and the bottom end of the rotating shaft 533 penetrates the fixed cylinder 511 and extends to the outside of the fixed cylinder 511, and the fixed cylinder 511 is slidably connected with the rotating shaft 533. The second gear 535 is installed at the bottom end of the rotating shaft 533, and the second gear 535 can be meshed with the adjusting mechanism 60 to drive the second gear 535 to rotate. Through the U-shaped connecting frame 47, the second gear 535 can pass through when the fixed cylinder 511 moves along the trajectory of the second transmission member 44.

[0043] like Figures 4 to 5 As shown, a connecting tube 532 is installed on the outer side of the bottom end of the rotating rod 531, and the top end of the rotating shaft 533 is located inside the connecting tube 532, and the connecting tube 532 is slidably connected with the rotating shaft 533. Two baffles 534 are installed on the outer side of the top end of the rotating shaft 533, and the two baffles 534 are arranged up and down with a gap. In the initial position, the baffle 534 located on the top contacts the inner top wall of the connecting tube 532.

[0044] When the tray 512 moves downward, due to the high moisture content of the undried workpiece, the tray 512 can move downward to the extreme position, so that the baffle 534 located below contacts the inner bottom wall of the connecting tube 532. At the same time, the tray 512 can drive the gear 2 535 to move downward to the extreme position through the rotating shaft 533. During the downward movement of the rotating shaft 533, the rotating shaft 533 slides on the rotating rod 531.

[0045] Continue to refer Figures 4 to 5 As shown, the limiting assembly 54 includes a rotating disk 541 installed at the top of the rotating rod 531 and a plurality of limiting members slidably arranged on the rotating disk 541. The plurality of limiting members are distributed in a circular array with the axis of the rotating disk 541 as the center, and a slide groove 542 is provided on the top of the rotating disk 541, and the shape of the slide groove 542 is arc-shaped.

[0046] Continue to refer Figures 4 to 5 As shown, the limiting member includes a slide bar 543, a support member 544 and two retaining rings 545. The slide bar 543 is slidably connected in the slide groove 542, and the top end of the slide bar 543 is slidably connected in the guide groove 55. The support member 544 is installed at the top end of the slide bar 543. In this embodiment, the support member 544 is plate-shaped, and in other embodiments, the support member 544 is rod-shaped. In the initial position, one end of the support member 544 away from the slide bar 543 is located at the top edge of the support tube 52. The turntable 541 is located between the two retaining rings 545, and the two retaining rings 545 are both installed on the outside of the slide bar 543.

[0047] When gear 2 535 rotates, gear 2 535 can drive the turntable 541 to rotate through the rotating rod 531 on the rotating shaft 533. During the rotation process of the turntable 541, the sliding rod 543 is pushed by the sliding groove 542 to move along the trajectory of the guide groove 55, so that the support member 544 extends out of the supporting tube 52, so that the support member 544 blocks the top of the workpiece to prevent the workpiece from falling directly when it rotates downward.

[0048] like Figures 2 to 3 and Figure 5 to Figure 6As shown, the adjustment mechanism 60 includes a fixing plate 61, a long rack 62, a short rack 1 63, a short rack 2 64 and a short rack 3 65. Both sides of the fixing plate 61 are fixed to both sides of the inner wall of the base 10 respectively. There are two long racks 62, which are respectively installed on both sides of the top of the fixing plate 61, and the long racks 62 can mesh with the gear 1 46.

[0049] There are multiple short racks 1 63, 2 short racks 64 and 3 short racks 65 and they are all arranged at equal intervals along the length direction of the fixed plate 61. The short racks 1 63, 2 short racks 64 and 3 short racks 65 can all mesh with the gear 2 535. When the short racks 1 63 or the short racks 3 65 mesh with the gear 2 535, the support member 544 can be driven to reset. When the short racks 2 64 mesh with the gear 2 535, the support member 544 can be driven to extend out of the support member 544. The short racks 1 63 and 2 short racks 64 are respectively installed on both sides of the top of the fixed plate 61 through support blocks. The teeth of the short racks 1 63 and 2 short racks 64 face opposite directions, and the thickness of the short racks 2 64 is greater than that of the short racks 1 63. The teeth of the short racks 1 63 and 3 short racks 65 face the same direction. The short racks 3 65 are installed on one side of the bottom of the fixed plate 61 through support blocks.

[0050] Working principle: When the workpiece is dried, the motor 33 is started. The motor 33 drives the mounting plates 41 in the multiple sliding mechanisms 40 to move around the trajectory of the transmission member 32 through the transmission member 32 on the transmission wheel 31. During the movement, the mounting plate 41 drives the fixed cylinder 511 to move around the trajectory of the transmission member 32. When the fixed cylinder 511 moves to the feed port of the drying chamber 20, the workpiece is placed on the tray 512 through an external automatic loading mechanism or manually and the workpiece is sleeved on the outside of the support cylinder 52. At this time, due to the high moisture content of the undried workpiece, the tray 512 can be moved down to the extreme position, thereby moving the gear 2 535 down to the extreme position so that the gear 2 535 is located below the short rack 63.

[0051] After the workpieces are placed, the mounting plate 41 is driven to move into the drying chamber 20 through the transmission member 32, thereby driving the workpieces into the drying chamber 20. When the gear 2 535 passes through the short rack 1 63, the gear 1 46 meshes with the long rack 62. At this time, under the action of the long rack 62, the gear 1 46 can be driven to rotate. The gear 1 46 drives the transmission member 2 44 to rotate through the transmission wheel 2 43 on the connecting rod 45, so that several workpieces move around the trajectory of the transmission member 2 44, so that the workpieces can be heated evenly.

[0052] When the workpiece passes through the drying chamber 20, gear 2 535 meshes with short rack 2 64. As the transmission wheel 1 31 continues to rotate, gear 2 535 drives the turntable 541 to rotate through the rotating rod 531 on the rotating shaft 533. The turntable 541 drives the support member 544 to extend out of the support tube 52 through the sliding rod 543, so that the support member 544 blocks the top of the workpiece.

[0053] When the workpiece moves to the end of the transmission member 32, driven by the transmission member 32, the mounting plate 41 rotates downward, and the workpiece rotates downward synchronously, so that the workpiece falls on the support member 544. At this time, under the action of the gravity of the workpiece, the support member 544 drives the connecting tube 532 to move downward through the rotating rod 531, and the connecting tube 532 drives the gear 2 535 on the rotating shaft 533 to move downward through the baffle 534. At this time, the tray 512 moves downward synchronously. Since the workpiece after complete drying is lighter than the workpiece after incomplete drying, the downward movement of the gear 2 535 driven by the workpiece after complete drying is less than the downward movement of the gear 2 535 driven by the workpiece after incomplete drying. At this time, the gear 2 535 with a small downward movement can engage with the short rack 3 65.

[0054] Under the action of the short rack three 65, the gear two 535 starts to rotate in the opposite direction to reset the support member 544. At this time, the completely dried workpiece loses the obstruction of the support member 544 and breaks away from the support tube 52, so that the completely dried workpiece can be automatically removed. At the same time, the incompletely dried workpiece continues to move along the trajectory of the transmission member 32 and enters the drying chamber 20 again for secondary drying. There is no need to use other equipment or manual labor to pick out the incompletely dried workpiece, and there is no need to manually place the secondary dried workpiece, thereby reducing labor costs.

[0055] When the workpiece is dried for the second time, since the workpiece is lighter than the undried workpiece, the workpiece driven by the second drying has a smaller downward movement of gear 2 535. Gear 2 535 with a small downward movement can engage with short rack 1 63, causing gear 2 535 to rotate in the opposite direction, so that the support member 544 is reset, which is convenient for the subsequent steps.

[0056] The present invention also provides a layered material drying method, which is performed using the layered material drying device, and comprises the following steps: S1: Put the workpiece on the tray 512 and put it on the outside of the support tube 52, then the motor 33 drives the transmission member 32 to rotate through the transmission wheel 31, and the transmission member 32 drives the workpiece on the tray 512 into the drying chamber 20 for drying; S2: During drying, the gear 1 46 meshes with the long rack 62. At this time, the gear 1 46 drives the transmission member 2 44 on the transmission wheel 2 43 to rotate through the connecting rod 45. The transmission member 2 44 drives the multiple workpieces to reciprocate around the track of the transmission member 2 44. When the gear 1 46 disengages from the long rack 62, all the workpieces are reset; S3: After the workpiece moves out of the drying chamber 20, the second gear 535 meshes with the second short rack 64, so that the support member 544 extends out of the support tube 52, and then driven by the transmission member 1 32, the workpiece rotates downward along the trajectory of the transmission member 1 32; S4: The downward workpiece drives the gear 2 535 downward through the support member 544. At this time, the completely dried workpiece drives the gear 2 535 to mesh with the short rack 3 65, so that the support member 544 is reset, and the completely dried workpiece falls. The workpiece that is not completely dried is driven by the transmission member 1 32 for secondary drying. S5: The second dried workpiece drives the gear 2 535 to move downward and mesh with the short rack 1 63, so that the support member 544 is reset to facilitate the subsequent steps.
