Description

Technical Field

[0001] This invention relates to the field of flocking technology for automotive interiors, and specifically to an automatic flocking device for automotive interior boxes. Background Technology

[0002] Flocking is a method of vertically fixing short fibers of 0.03-0.5cm onto a substrate coated with adhesive. In car interiors, storage boxes for placing items are usually set in the center armrest or below the door armrest. The top of the storage box is open. Flocking inside the storage box can make the storage box have a strong three-dimensional effect, bright colors and a soft feel, thus improving the comfort and texture of the car.

[0003] Currently, when flocking automotive interior boxes, a robotic arm is used to drive a single flocking nozzle fixed on it for automatic flocking. During flocking, the robotic arm needs to drive the flocking nozzle to extend into the interior box and continuously rotate and move it to flock the inner sides of the interior box in different directions. Because a large number of movements are required to change the flocking position, and it is not possible to flock multiple sides at the same time, the flocking efficiency is relatively low, and flocking a single interior box takes a long time. Summary of the Invention

[0004] The purpose of this invention is to solve the problems of relatively low flocking efficiency and long flocking time for a single interior box in existing automatic flocking equipment for automotive interior boxes. This invention provides an automatic flocking equipment for automotive interior boxes.

[0005] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0006] An automatic flocking device for automotive interior boxes includes a fixedly installed support for placing the interior box and a movably installed lifting frame. A bracket and a drive plate are fixedly connected to the upper and lower sides of the front end of the lifting frame, respectively. A stroke component is movably installed in the drive plate. The stroke component includes a notched gear rotatably installed in the drive plate. A stud is fixedly connected to the top of the notched gear, and a threaded sleeve is threaded onto the top of the stud. A support plate is fixedly fitted onto the threaded sleeve. A circumferential flocking component is movably connected to the drive plate. The circumferential flocking component includes two flocking tubes movably inserted into the drive plate. The flocking tubes are rotatably connected to the support plate. A mixing head is rotatably connected to the top of the flocking tubes. An oblique suction groove is formed on the side wall of the mixing head. A flock box is fixedly connected to one side of the mixing head. A vertical flocking component is fixedly connected to the bottom of the drive plate. The vertical flocking component includes a star-shaped platform movably engaged between the flocking tubes. A flock groove is formed inside the star-shaped platform. Stops are slidably connected to the left and right sides of the flock groove. A dispersion cover communicating with the center of the flock groove is fixedly connected to the bottom of the star-shaped platform.

[0007] Furthermore, the stroke assembly also includes two rotating gear rings rotatably mounted on the left side of the inner cavity of the drive disk, the rotating gear rings being meshed together, a drive gear being driven mounted on the right side of the inner cavity of the drive disk, the drive gear being meshed with the rotating gear rings, and a toothed ring being fixedly connected to the top of the rotating gear rings.

[0008] Furthermore, the outer periphery of the missing gear includes two sets of opposing arc segments and tooth segments, and the outer periphery of the missing gear ring includes a tooth groove corresponding to the tooth segment of the missing gear, and the edge of the missing gear ring engages with the arc segment of the missing gear.

[0009] Furthermore, the down-spraying tube is slidably engaged in the rotating gear ring, the bottom of the down-spraying tube expands into a disc shape and movably abuts against the side wall of the star-shaped platform, and a cone-shaped nozzle is opened at the bottom of the down-spraying tube.

[0010] Furthermore, the mixing head and the down box are both fixedly mounted on the tray. A three-way pipe connected to a pressurized air source is externally connected between the top of the mixing head and the bottom of the mixing head. The lower port of the mixing head is connected to the down spraying pipe. The inner diameter of the mixing head is smaller than the inner diameter of the down spraying pipe.

[0011] Furthermore, the inclined suction grooves are respectively connected to the mixing head and the wool box, and a throttling disc is fixedly installed inside the inclined suction grooves.

[0012] Furthermore, the vertical flocking assembly also includes two hinges movably connected between the blocks, with wedges movably connected to the hinges, and elastic levers slidably inserted into both the front and rear sides of the star-shaped platform and movably engaged with the wedges, the elastic levers movably passing through the drive disc.

[0013] Furthermore, the elastic lever is located at the bottom of the side wall of the card holder.

[0014] The beneficial effects of this invention are as follows:

[0015] 1. In this invention, the two spray tubes are driven to move down intermittently in segments to spray down through the stroke component, and the two spray tubes spray down in a synchronous circumferential manner, thereby improving the spraying efficiency. When the spray tubes rise to the maximum distance, the vertical flocking component is automatically operated, and the dispersion cover is used to disperse the down spraying down, which facilitates quick and comprehensive down spraying of the interior box.

[0016] 2. In this invention, two spray tubes drive the conical nozzles to rotate synchronously, which can spray the inner cavity of the interior box with fabric at the same time, thus speeding up the spraying process. When the conical nozzles face the star-shaped platform, the conical nozzles automatically seal to avoid excessive cross-spraying. At the same time, the spraying height of the spray tubes relative to the interior box can be adjusted to avoid affecting the uniformity of the spraying.

[0017] 3. This invention utilizes a circumferential flocking component and a vertical flocking component to spray flocking around the inner cavity and bottom of the interior box in stages, making the flocking process comprehensive and convenient. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0029] like Figure 1-9As shown, an automatic flocking device for automotive interior boxes includes a fixedly installed support 1 for placing the interior box and a movably installed lifting frame 2. A card holder 3 and a drive plate 4 are fixedly connected to the upper and lower sides of the front end of the lifting frame 2, respectively. A travel component 5 is movably installed in the drive plate 4. The travel component 5 includes a missing gear 54 rotatably installed in the drive plate 4. A stud 55 is fixedly connected to the top of the missing gear 54, and a threaded sleeve 56 is threaded onto the top of the stud 55. A support plate 57 is fixedly sleeved on the threaded sleeve 56. A circumferential flocking component 6 is movably connected to the drive plate 4. The circumferential flocking component 6 includes a movable insertion... Two flocking pipes 61 are located in the drive disk 4. The flocking pipes 61 are rotatably connected to the support plate 57. A mixing head 63 is rotatably connected to the top of the flocking pipes 61. An inclined suction groove 64 is opened on the side wall of the mixing head 63. A flock box 65 is fixedly connected to one side of the mixing head 63. A vertical flocking assembly 7 is fixedly connected to the bottom of the drive disk 4. The vertical flocking assembly 7 includes a star-shaped platform 71 that is movably snapped between the flocking pipes 61. A flock groove 72 is provided inside the star-shaped platform 71. A stop block 73 is slidably connected to both the left and right sides of the flock groove 72. A dispersion cover 77 that communicates with the center of the flock groove 72 is fixedly connected to the bottom of the star-shaped platform 71.

[0030] More specifically, during flocking, after the interior box is placed in the support 1, the drive stroke component 5 drives the two flocking pipes 61 to move down intermittently in segments to spray flocking, and the two flocking pipes 61 spray flocking in a circular motion simultaneously. When the flocking pipes 61 rise to the maximum distance, the vertical flocking component 7 is automatically operated, and the flocking is dispersed downward using the dispersion cover 77. This design facilitates comprehensive and rapid flocking of the interior box.

[0031] Specifically, such as Figure 3 and Figure 5 As shown, the stroke assembly 5 also includes two rotating gear rings 51 rotatably mounted on the left side of the inner cavity of the drive disk 4, which are meshed together. A drive gear 52 is driven and mounted on the right side of the inner cavity of the drive disk 4, which meshes with the rotating gear rings 51. A toothed ring 53 is fixedly connected to the top of the rotating gear rings 51.

[0032] During flocking, the drive gear 52 drives the rotating gear ring 51 that meshes with it to rotate, and the rotating gear ring 51 meshes with and drives the adjacent rotating gear ring 51 to rotate, so that the two flocking pipes 61 can rotate synchronously to spray flock, thus speeding up the flocking process.

[0033] Specifically, such as Figure 5As shown, the missing gear 54 has two sets of opposing arc segments and tooth segments around its periphery. The missing gear ring 53 has a tooth groove around its periphery that corresponds to the tooth segment of the missing gear 54. The edge of the missing gear ring 53 engages with the arc segment of the missing gear 54. Initially, the missing gear ring 53 uses the arc segment on the missing gear 54 to limit the missing gear 54. When the rotating gear ring 51 drives the missing gear ring 53 to rotate, and drives the tooth groove on the missing gear ring 53 to the side of the missing gear 54, the missing gear ring 53 meshes with the missing gear 54. The missing gear 54 is driven to drive the stud 55 to rotate, which drives the screw sleeve 56 to move the support plate 57 in the vertical direction accordingly, so as to adjust the spraying height of the spraying pipe 61.

[0034] Specifically, such as Figure 3 and Figure 5 As shown, the spray tube 61 is slidably engaged in the rotating gear ring 51. The bottom of the spray tube 61 expands into a disc shape and moves against the side wall of the star-shaped platform 71. A cone-shaped nozzle 62 is provided at the bottom of the spray tube 61.

[0035] Specifically, such as Figure 3 As shown, the mixing head 63 and the fluff box 65 are both fixedly installed on the support plate 57. A three-way pipe connected to a pressurized air source is connected to the top of the mixing head 63. The lower end of the mixing head 63 is connected to the fluff spraying pipe 61. The inner diameter of the mixing head 63 is smaller than the inner diameter of the fluff spraying pipe 61. The inclined suction groove 64 connects the mixing head 63 and the fluff box 65 respectively. A throttling plate is fixedly installed inside the inclined suction groove 64. Initially, the fluff box 65 is filled with short fibers. When pressurized air is introduced into the mixing head 63 from top to bottom, a negative pressure zone appears on the upper side of the connection section between the mixing head 63 and the fluff spraying pipe 61 according to the Venturi effect. The short fibers in the fluff box 65 are extracted through the inclined suction groove 64 and automatically discharged into the fluff spraying pipe 61 after the pumping amount is controlled by the throttling plate.

[0036] Specifically, such as Figure 6-9 As shown, the vertical flocking assembly 7 also includes two hinges 74 movably connected between the stops 73. A wedge rod 75 is movably connected to the hinge 74. A spring lever 76 is slidably inserted on both the front and rear sides of the star-shaped platform 71 and is movably engaged with the wedge rod 75. The spring lever 76 is movably inserted through the drive disc 4. The spring lever 76 is located at the bottom of the side wall of the bracket 3. By using the passive compression of the spring lever 76 by the bracket 3, the wedge rod 75 is driven to pull the hinge 74 to retract. The stops 73 then automatically open the flocking groove 72 to receive the short flocking released by the flocking pipe 61, so as to flock the bottom of the interior box cavity using the dispersion cover 77.

[0037] Working principle: Initially, the flocking box 65 is filled with short fibers. During flocking, after the interior trim box is placed in the support 1, the operating equipment controls the lifting frame 2 to move downward, driving the flocking pipe 61 so that the conical nozzle 62 aligns with the edge of the interior trim box port. Pressurized air is then introduced from top to bottom into the mixing head 63. Because the inner diameter of the mixing head 63 is smaller than the inner diameter of the flocking pipe 61, a negative pressure zone appears on the upper side of the connection section between the mixing head 63 and the flocking pipe 61 according to the Venturi effect. The short fibers in the flocking box 65 are extracted through the inclined suction groove 64 and automatically discharged into the flocking pipe 61 after the extraction volume is controlled by the throttling disc. They are then sprayed out from the conical nozzle 62, thus achieving flocking of the interior trim box's inner wall. During this process, the control gear 52 drives the rotating gear ring 51 meshing with it to rotate. The rotating gear ring 51 then drives another adjacent rotating gear ring 51 to rotate, and the two flocking pipes 61 rotate synchronously, accelerating the flocking process. When the rotating gear ring... When the toothed ring 53 rotates, and the tooth groove on the toothed ring 53 rotates to the side of the toothed gear 54, the toothed ring 53 meshes with the toothed gear 54. The toothed gear 54 is driven to rotate the stud 55, which drives the screw sleeve 56 to move the support plate 57 down. The spraying height of the conical nozzle 62 is then lowered. When the toothed ring 53 rotates past the tooth section of the toothed gear 54, the toothed gear 54 is driven to engage the arc section with the smooth section of the toothed ring 53. The toothed gear 54 is then limited, ensuring the stability of the spraying at a fixed height. When the spraying tube 61 rises to its maximum distance, the conical nozzle 62 turns to the stop block 73 and is sealed by the stop block 73. The spraying stops. Simultaneously, the clamp 3 passively squeezes the spring lever 76, the wedge rod 75 pulls the hinge 74 to retract, and the stop block 73 automatically opens the pile groove 72 to receive the short pile released by the spraying tube 61, so as to use the dispersion cover 77 to flock the bottom of the interior box cavity.
