Description

Technical Field

[0001] The invention relates to the technical field of automobile injection molding parts processing, in particular to a drying machine for injection molding parts production and processing. Background Art

[0002] Many automotive parts, such as engine compartment components, door panels, and interior trim panels, are made of plastic, so they are generally processed using injection molding. However, after injection molding, these injection-molded parts need to be dried to avoid defects such as bubbles and silver streaks because the material itself is prone to moisture absorption or there is a certain amount of moisture after injection molding.

[0003] When drying existing automotive injection molded parts, commonly used equipment includes a hot air circulation oven. The injection molded parts to be dried are transferred into the oven through a transfer device, and then the placed injection molded parts are dried for a certain period of time by circulating hot air at a certain temperature.

[0004] The shortcomings of existing injection molded parts drying equipment are: although the existing hot air circulation oven can complete the drying of injection molded parts, the air inlet position of the oven is generally fixed at the top or side, and the batches of injection molded parts are placed in the middle position inside the oven. Injection molded parts are generally fixedly placed without movement or with a single movement method. The hot air delivered by the oven is difficult to fully act on various positions of the injection molded parts, especially some injection molded parts such as automobile interior door panels have detailed positions such as grooves. The existing oven is not convenient for effectively drying these positions, and it is easy to cause local positions to be under-dried, affecting the drying effect. Summary of the Invention

DETAILED DESCRIPTION

[0034] The specific embodiments of the present invention are described in detail below, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0035] like Figures 1-9 As shown, a dryer for injection molding production and processing is used for drying injection molding of automobile door panels. The dryer comprises a drying box 1. A hot air conveying mechanism is provided at the bottom of the drying box 1, and an exhaust pipe 3 is provided at the top. The hot air conveying mechanism is used to convey hot air into the drying box 1 to dry the injection molding placed inside the drying box 1, and the water vapor exhausted during the drying process is discharged through the exhaust pipe 3. The exhaust pipe 3 can be equipped with a negative pressure pump for suction. At the same time, the exhaust pipe 3 can also be connected to the hot air conveying mechanism for hot air circulation. A dehumidification mechanism can be installed between the two to remove moisture in the circulating hot air. The dryer is also equipped with a controller 2, wherein the controller 2 includes control modules such as a temperature control device and a motor control device, which are used to set and control parameters such as the temperature and conveying speed of the hot air conveyed by the hot air conveying mechanism.

[0036] The dryer also includes an injection molded part clamping and rotating mechanism, which includes a turntable 7, a clamping and swinging mechanism, and a lifting air guide assembly. The turntable 7 is rotatably arranged inside the drying box 1, and a plurality of clamping and swinging mechanisms are provided, which are equidistantly distributed on the turntable 7 in the circumferential direction. Each group of clamping and swinging mechanisms is used to clamp the injection molded parts, and each group of clamping and swinging mechanisms includes a swinging seat 14 for driving the injection molded parts to swing back and forth. Each group of clamping and swinging mechanisms is equipped with a lifting air guide assembly for drying the injection molded parts that swing with the swinging seat 14. The lifting air guide assembly realizes a dynamic drying effect through continuous lifting and lowering motion and the injection molded parts continuously swing back and forth with the swinging seat 14, so as to ensure that the blown hot air fully acts on different detail positions of the injection molded parts, including some special-shaped positions such as grooves, to avoid local under-drying or over-drying.

[0037] In some embodiments, combined Figure 2 、 Figure 8 and Figure 9 As shown, a bottom plate 11 is installed at the inner bottom of the drying box 1, and the turntable 7 is located above the bottom plate 11. A slip ring 30 is fixedly provided on the outer edge of the turntable 7. An annular groove 29 is provided on the bottom plate 11, and the slip ring 30 is slidably connected to the annular groove 29. Here, the slip ring 30 is embedded in the annular groove 29, and the bottom of the slip ring 30 can contact the annular groove 29 through balls or pulleys equidistantly distributed in the circumferential direction; a through opening for connecting the air outlet end of the hot air conveying mechanism and the bottom space of the turntable 7 is provided on the bottom plate 11, and a rotating drive shaft 8 for driving the turntable 7 to rotate is installed inside the drying box 1, where one end of the rotating drive shaft 8 can be fixedly connected to the turntable 7, and the other end is connected to the main shaft of the drive motor.

[0038] In some embodiments, combined Figure 4 and Figure 6 As shown, each set of clamping and swinging mechanisms also includes an axis frame 24, a linkage horizontal axis 23, a fixed clamp frame 13 and a sliding clamp. The axis frame 24 is fixedly installed on the turntable 7 and is close to the edge of the turntable 7. The linkage horizontal axis 23 is rotatably connected to the axis frame 24. The bottom of the swing seat 14 is fixedly connected to the linkage horizontal axis 23 through a bracket. The fixed clamp frame 13 is fixedly installed on the swing seat 14. The sliding clamp is slidably set on the swing seat 14, and the sliding clamp and the fixed clamp frame 13 are used to clamp the injection molded parts together; a swing driving mechanism is provided at the end of the linkage horizontal axis 23 of each set of clamping and swinging mechanisms away from the swing seat 14.

[0039] Among them, the sliding clamp includes a sliding clamp frame 12 and a threaded adjustment rod 27. The sliding clamp frame 12 and the fixed clamp frame 13 are parallel to each other, and the sliding clamp frame 12 is slidingly connected to the swing seat 14. A sliding groove or an installation guide rail can be opened on the swing seat 14 so that the sliding clamp frame 12 can be slidably installed. A mounting block 26 is fixedly installed on the swing seat 14. The threaded adjustment rod 27 passes through the mounting block 26 and is threadedly connected to the mounting block 26. The end of the threaded adjustment rod 27 is rotatably connected to the sliding clamp frame 12.

[0040] When the injection molded part needs to be fixed and clamped, the injection molded part is placed between the fixed clamping frame 13 and the sliding clamping frame 12, and then the threaded adjustment rod 27 is rotated to push the sliding clamping frame 12 so that the sliding clamping frame 12 and the fixed clamping frame 13 can fix and clamp the injection molded part together.

[0041] It should be noted that the thickness and width of the frame of the sliding clamp frame 12 and the fixed clamp frame 13 can be set to be smaller to ensure a smaller obstruction area. In addition, holes can be opened on the sliding clamp frame 12 and the fixed clamp frame 13 to form a hollow structure to further reduce obstruction. It can also be other shapes and is not limited to the shape of a square frame.

[0042] In some specific embodiments, reference Figures 3 to 6As shown, each set of swing drive mechanisms includes a reciprocating screw 17, a linkage frame 21 and a sliding column 20. The reciprocating screw 17 is vertically connected to the turntable 7 and is close to the position of the corresponding linkage horizontal axis 23. A screw sleeve 18 is connected to the reciprocating screw 17. During the unidirectional rotation of the reciprocating screw 17, the screw sleeve 18 can reciprocate up and down along the reciprocating screw 17. Here, the reciprocating screw 17 is a mechanical transmission component that can realize the automatic reciprocating motion of the nut on the screw. Usually, bidirectional linear motion under unidirectional rotation is achieved through special design. The screw adopts alternating left-hand and right-hand threads. When the nut moves to the point where the thread direction changes, the motion direction is automatically reversed; a limiting guide rail 22 fixedly connected to the turntable 7 is provided in parallel on one side of the reciprocating screw 17. The screw sleeve 18 is fixed to the turntable 7. The limiting guide rail 22 is slidably connected to ensure that during the rotation of the reciprocating screw 17, the screw sleeve 18 can only move in a straight line and cannot rotate therewith. The linkage frame 21 is fixedly connected to the linkage horizontal shaft 23 at one end close to the reciprocating screw 17, and the linkage frame 21 is vertically distributed to the linkage horizontal shaft 23. When the swing seat 14 is in a horizontal position, the linkage frame 21 is in a horizontal position, and the slide column 20 is fixedly connected to the outer wall of the screw sleeve 18, and the slide column 20 vertically passes through the linkage frame 21. The slide column 20 can slide relative to the linkage frame 21, and when the linkage frame 21 is in the horizontal position, the slide column 20 is at one end of the linkage frame 21 close to the linkage horizontal shaft 23. At the same time, the screw sleeve 18 is at the midpoint of the reciprocating screw 17. A linkage gear group is provided inside the drying box 1 for driving each reciprocating screw 17 to rotate.

[0043] Among them, the linkage gear set includes a gear ring 9 and a driven gear 10. The top of each reciprocating screw 17 is coaxially fixedly connected to the driven gear 10. The gear ring 9 is arranged directly above the turntable 7, and the gear ring 9 is fixedly connected to the inner top of the drying box 1 through a hanger. Each driven gear 10 is engaged with the gear ring 9.

[0044] It should be noted that the center of the gear ring 9 is aligned with the center of the turntable 7 , and the distributed driven gears 10 are equidistantly distributed around the gear ring 9 in the circumferential direction.

[0045] When the turntable 7 drives the clamped injection molded part to rotate, the driven gear 10 corresponding to each set of clamping and swinging mechanisms rolls along the fixed gear ring 9 to realize rotation, so that each driven gear 10 drives the corresponding reciprocating screw 17 to rotate, and the reciprocating screw 17 drives the screw sleeve 18 to move longitudinally, and the screw sleeve 18 drives the slide post 20 to move synchronously. During the movement, the slide post 20 squeezes the linkage frame 21 to one side and slides along the linkage frame 21, so that the linkage frame 21 drives the linkage horizontal shaft 23 to rotate, and the linkage horizontal shaft 23 drives the swing The movable seat 14 deflects to one side, and when the screw sleeve 18 moves to the end of the reciprocating screw 17, it moves back in the opposite direction, thereby driving the sliding column 20 to squeeze the linkage frame 21 to the other side, so that the linkage frame 21 drives the linkage horizontal axis 23 to reverse, so that the swing seat 14 deflects to the other side, so that the swing seat 14 can swing back and forth, so that the clamped injection molded parts can swing back and forth while the turntable 7 revolves. In conjunction with the lifting air guide component, it is convenient to fully dry different positions of the injection molded parts, and the reciprocating swinging is also conducive to moisture loss.

[0046] In some embodiments, combined Figure 4 and Figure 5 As shown, each set of lifting air guide components includes an air guide nozzle, a telescopic tube 16 and a lifting transmission mechanism. There are two groups of telescopic tubes 16, which are distributed on both sides of the clamping and swinging mechanism. It should be noted here that if the swinging direction of the clamping and swinging mechanism is defined as the left and right sides, then the telescopic tubes 16 are distributed on the front and back sides. One end of each set of telescopic tubes 16 is fixedly connected to the edge of the turntable 7 and is connected to the bottom space of the turntable 7. The other end is fixedly installed with an air guide nozzle, and the air guide nozzle is connected to the telescopic tube 16. The two groups of air guide nozzles are symmetrically distributed, and the two groups of air guide groups are fixedly connected by a cross bar. It should also be noted that the telescopic tube 16 here is composed of a fixed tube and a sliding tube that slides through the fixed tube, which can be retracted and guide air; one group of telescopic tubes 16 is connected to the linkage horizontal axis 23 through a lifting transmission mechanism.

[0047] Among them, such as Figure 6 and Figure 7 As shown, the lifting transmission mechanism includes a sector gear 25 and a rack 28. The sector gear 25 is fixedly mounted on the linkage horizontal shaft 23. Two racks 28 are provided, and the two racks 28 are symmetrically distributed on both sides of the sector gear 25. The number of teeth on the rack 28 and the size of the sector gear 25 can be designed according to actual needs to ensure that when the swing seat 14 is in a horizontal position, the sector gear 25 is between the two racks 28, the effective tooth part faces downward, and does not contact any rack 28. When the sector gear 25 rotates clockwise or counterclockwise, it engages with the rack 28 on the corresponding side and drives the corresponding rack 28 to move without contacting the rack 28 on the other side. The two racks 28 are fixedly connected to the same air guide nozzle.

[0048] During the forward and reverse rotation of the linkage horizontal shaft 23, it drives the sector gear 25 to deflect forward and reverse synchronously. When the sector gear 25 rotates clockwise, it drives the rack 28 on the corresponding side to rise, and the rack 28 pushes the air guide nozzle upward, and the air guide nozzle stretches the telescopic tube 16. When the linkage horizontal shaft 23 drives the sector gear 25 to reverse, the raised rack 28 drops and resets. When the sector gear 25 rotates and contacts the rack 28 on the other side, it drives it to rise, thereby realizing the raising of the air guide nozzle again, so that the air guide nozzle can be repeatedly raised and lowered.

[0049] In some specific embodiments, such as Figure 7 As shown, the air guide nozzle includes a hollow plate 15 and an air outlet inclined nozzle 19. The hollow plate 15 is fixedly connected to the telescopic end of the telescopic tube 16, and the hollow plate 15 is communicated with the telescopic tube 16. The hollow plate 15 can be fixedly connected to the rack 28. Two groups of air outlet inclined nozzles 19 are provided. The two groups of air outlet inclined nozzles 19 are fixedly installed on one side of the hollow plate 15 close to the clamping and swinging mechanism, and the two groups of air outlet inclined nozzles 19 are symmetrically distributed, that is, one group is inclined upward and the other group is inclined downward, so that the hot air can effectively cover the injection molded parts and improve the drying effect.

[0050] It should be noted that the width of the hollow plate 15 itself and the number of the outlet inclined nozzles 19 can be set according to the actual injection molded parts to ensure that the injection molded parts are still within the blowing range of the outlet inclined nozzles 19 during the swinging process.

[0051] In some embodiments, combined Figure 2 and Figure 8 As shown, the hot air delivery mechanism includes an air duct 4 and a fan 5. The air duct 4 is fixedly installed at the bottom of the drying box 1, and the top of the air duct 4 extends to the bottom position of the turntable 7 to achieve communication. The fan 5 is fixedly installed at the bottom of the air duct 4. The fan 5 is an axial flow fan for conveying air upward. An electric heating element 6 is provided near the top of the air duct 4. The electric heating element 6 can be an electric heating plate or an electric heating wire. It generates heat when powered on, and the temperature can be set and controlled by a temperature control device.

[0052] The air delivered by the fan 5 passes through the air duct 4 and the electric heating element 6 to be heated, and then is distributed to each telescopic tube 16 through the bottom of the turntable 7, and finally sprayed onto the injection molded part through the air guide nozzle to achieve hot air drying.

[0053] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in conjunction with specific application scenarios:

[0054] First, place the multiple injection molded parts to be dried between the corresponding fixed clamping frame 13 and the sliding clamping frame 12, then rotate the threaded adjustment rod 27 to push the sliding clamping frame 12 so that the sliding clamping frame 12 and the fixed clamping frame 13 can clamp the injection molded parts together.

[0055] Then close the door and set the hot air temperature, delivery speed and rotation speed of the turntable 7 through the controller 2. After the fan 5 is started, the delivered air passes through the air duct 4 and the electric heating element 6 to be heated. Then, it is divided into each telescopic tube 16 through the bottom of the turntable 7 and finally sprayed onto the injection molded parts through the air guide nozzle to achieve hot air drying.

[0056] And the turntable 7 drives the injection molded parts distributed in the circumferential clamping to revolve. During the revolution, the driven gear 10 corresponding to each set of clamping and swinging mechanisms rolls along the fixed gear ring 9 to realize rotation. In this way, each driven gear 10 drives the corresponding reciprocating screw 17 to rotate, and the reciprocating screw 17 drives the screw sleeve 18 to move longitudinally. The screw sleeve 18 drives the slide column 20 to move synchronously. The slide column 20 squeezes the linkage frame 21 to one side during the movement and slides along the linkage frame 21, so that the linkage frame 21 drives The linkage horizontal shaft 23 rotates, and the linkage horizontal shaft 23 drives the swing seat 14 to deflect to one side. When the screw sleeve 18 moves to the end of the reciprocating screw 17, it moves back in the opposite direction, thereby driving the slide column 20 to squeeze the linkage frame 21 to the other side, so that the linkage frame 21 drives the linkage horizontal shaft 23 to reverse, so that the swing seat 14 deflects to the other side, so that the swing seat 14 can swing back and forth, so that the clamped injection molded parts can swing back and forth while rotating with the turntable 7, which is beneficial to the loss of moisture during the drying process.

[0057] At the same time, during the positive and negative rotation of the linkage horizontal shaft 23, it drives the sector gear 25 to rotate synchronously in the positive and negative directions. When the sector gear 25 rotates clockwise, it drives the rack 28 on the corresponding side to rise, and the rack 28 pushes the air guide nozzle upward, and the air guide nozzle stretches the telescopic tube 16. When the linkage horizontal shaft 23 drives the sector gear 25 to reverse, the raised rack 28 drops and resets. When the sector gear 25 rotates and contacts the rack 28 on the other side, it drives it to rise, thereby realizing the raising of the air guide nozzle again, so that the air guide nozzle can be repeatedly raised and lowered. When the injection molded part swings back and forth, the air guide nozzle is continuously raised and lowered in the process of blowing hot air, realizing a dynamic drying effect. Since the injection molded part will have different angle changes during the swinging process, the longitudinal position will also have different height changes, that is, the air guide nozzle and the injection molded part have multi-angle and multi-directional relative motion, which is convenient for ensuring that the hot air blown fully acts on different detail positions of the injection molded part at close range, including some special-shaped positions such as grooves, to avoid local under-baking or over-baking.

[0058] The above disclosures are only a few specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
