Description

Technical Field

[0001] The utility model belongs to the technical field of automobile seat cushion foaming production, and particularly relates to a foaming injection device for automobile seat cushion production. Background Art

[0002] The car seat cushion manufacturing process involves mixing component A, isocyanate, and component B, polyol, through a foaming device, heating them evenly, and then spraying them out. Within the constraints of a fixed mold, the car seat cushion solidifies and forms in 1 minute. It is also soft and wear-resistant, extending the life of the car seat cushion and conforming to the occupant's sitting posture. The foaming raw materials are injected into the mold through an injection gun, and the car seat cushion is integrally formed through the mold. After injecting the foaming material into the mold, the injection gun resets and exits the mold. Because the raw materials in the gun cannot be completely discharged, a small amount will remain in the gun barrel. It is also impossible to wait for the foaming material in the gun to fall completely into the mold, which reduces production efficiency. As a result, the injection gun is prone to dripping foam due to movement during the reset process, contaminating the machine and the floor, making cleaning more difficult.

[0003] The document with authorization announcement number CN221562124U discloses an anti-drip device for the injection gun head in the production of automobile seat cushion foaming, including a five-axis robot arm, an execution end of the five-axis robot arm is provided with an injection gun head, and a shielding mechanism is provided on the injection gun head. The shielding mechanism includes a shielding plate, and the outer wall of the injection gun head is hinged with a shielding plate, and a leak-proof sponge layer is provided on the shielding plate. The shielding plate rotates so that the leak-proof sponge layer is in a compressed state and contacts the discharge port of the injection gun head. When the injection gun head injects material into the mold, the shielding plate deflects away from the discharge port of the injection gun head, so that the injection gun head can inject material normally. When the gun head completes injection, the shielding plate rotates so that the leak-proof sponge layer contacts the injection gun head, thereby shielding the discharge port of the injection gun head when the injection gun head retracts and resets, thereby avoiding contamination caused by dripping of residual foaming material in the gun.

[0004] However, the device still has the following problems: during the rotation of the installation sleeve, the pressure at the edge of the leak-proof sponge layer is lower than the pressure in the middle part, which affects both the cleaning effect of the injection gun head and the utilization rate of the sponge edge.

[0030] Example 1

[0031] This embodiment provides a foaming injection device for the production of automobile seat cushions, including a robotic arm a, an injection gun head b, and a shielding structure arranged at the discharge port of the injection gun head b. The shielding structure includes a frame 1, a shielding plate 2 arranged on the frame 1, the end of which is rotatably connected to the frame 1 and located at the lower end of the discharge port of the injection gun head b, and an absorption block 3 that is detachably arranged on the shielding plate 2.

[0032] It is understandable that the robot arm a and the injection gun head b are commonly used structures in this field, so the specific structures of the two will not be expanded. The execution end of the robot arm a is connected to the injection gun head b, and the frame 1 is located on one side of the injection gun head b. By adjusting the frame 1, the position of the shielding disk 2 and the absorption block 3 relative to the discharge port of the injection gun head b is adjusted. Even if the horizontal projection of the shielding disk 2 can completely cover the discharge port of the injection gun head b, the absorption block 3 is also in contact with the discharge port of the injection gun head b. The shielding disk 2 is driven to rotate, so that the absorption block 3 moves within a certain range relative to the injection gun head b. On the basis of blocking the discharge port, the residual foaming material at the discharge port can also be wiped off.

[0033] In this embodiment, the frame 1 includes a mobile base 11, a fixed vertical plate 12 mounted on the mobile base 11, and a rotating column structure 13 mounted on the fixed vertical plate 12 and connected to the shielding plate 2. The lower end of the mobile base 11 may be provided with directional wheels to facilitate movement, and the fixed vertical plate 12 may be fixedly connected to the mobile base 11 or hingedly connected to the mobile base 11. When fixedly connected, the device operates with the injection nozzle b held vertically; when hinged, the device can adjust the angle of the injection nozzle b to facilitate shielding and cleaning operations.

[0034] In this embodiment, the rotating column structure 13 includes a cavity 131, a column 132 rotatably connected to the cavity 131 through a bearing 134, a cavity 2 135 connected to the cavity 131, and a motor 136 arranged in the cavity 2 135 and with the output end connected to the column 132; the shielding plate 2 is provided with a through hole 133 for the column 132 to pass through.

[0035] In this embodiment, the shielding disk 2 includes a disk body 21, a connecting plate 22 arranged at the side end of the disk body 21 and rotatably connected to the rotating column structure 13, a mounting groove 23 arranged at the upper end of the disk body 21 and used to install the absorption block 3, a mounting ring 24 installed on the injection gun head b, a driving bar 25 arranged on the lower bottom surface of the mounting ring 24, an arc-shaped groove 26 arranged on the disk body 21, a gear 27 rotatably connected in the arc-shaped groove 26 and meshing with the driving bar 25, a sliding cavity arranged at the lower end of the arc-shaped groove 26 and connected to the arc-shaped groove 26, a rack 28 slidably connected in the sliding cavity and meshing with the gear 27, and a driving rod 29 arranged at the side end of the rack 28 and passing through the mounting groove 23 for connection with the absorption block 3.

[0036] In this embodiment, the absorption block 3 includes a frame body 31 slidably connected in the mounting groove 23 and connected to the driving rod 29 , and a block body 32 disposed in the frame body 31 .

[0037] It is worth noting that in order to improve the utilization rate of the absorption block 3, that is, to be able to use various positions of the block 32, the working principle of this device is as follows: first, install the mounting ring 24 at the discharge port of the injection gun head b, start the motor 136 to drive the disk 21 to rotate, and the gear 27 in the arc groove 26 moves relative to the drive bar 25, and the gear 27 rotates, thereby driving the rack 28 to slide along the direction specified by the sliding cavity. Finally, under the action of the drive rod 29, the absorption block 3 moves in the mounting groove 23, further increasing the absorption area of ​​the block 32.

[0038] Among them, there are multiple gears 27 in the arc-shaped grooves 26, and the shape of the arc-shaped grooves 26 is consistent with the rotation direction of the disk body 21 to ensure that the gear 27 can engage with the drive bar 25 without disengagement. The length of the sliding cavity is greater than or equal to the length of the arc-shaped grooves 26, and the directions of the two can be inconsistent. The size of the rack 28 can be selected to cover all the gears 27 to ensure that the rack 28 can be effectively driven. A connecting channel is provided between the sliding cavity and the mounting groove 23 to allow the drive rod 29 to pass and slide.

[0039] As a further preferred embodiment of this embodiment, the rack 28 includes a rack body 281, a limiting groove 282 provided on the inner side wall of the arc-shaped groove 26, a limiting block 283 provided on the side end of the rack body 281 away from the driving rod 29 and slidably connected to the limiting groove 282, and a roller 284 provided at the lower end of the rack body 281. This arrangement is intended to enhance the stability of the rack and ensure that the gear and rack are meshed and not disengaged, while also reducing the resistance encountered by the rack when sliding.

[0040] As a further preferred embodiment of the present invention, the absorption block 3 further includes a second roller 33 provided at the lower end of the frame 31 , for reducing the resistance encountered by the frame 31 when sliding.

[0041] Example 2

[0042] This embodiment optimizes the structure based on the embodiment 1, as follows:

[0043] In this embodiment, the frame 1 further includes a positioning ring 14 disposed on the injection gun head b, a connecting block 15 disposed on the side of the positioning ring 14, and a connecting block 16 disposed on the upper end of the fixed riser 12 and detachably connected to the connecting block 15. The connecting block 15 and the connecting block 16 can be connected using any existing structure, such as a latch. This arrangement has the following advantages: first, it assists in positioning and installing the frame 1; second, it further improves the stability of the connection between the frame 1 and the injection gun head b.

[0044] Example 3

[0045] The difference between this embodiment and embodiment 1 is that the second cavity 135 and the motor 136 are eliminated, and the shielding plate 2 further includes a handle provided on the end of the connecting plate 22 away from the plate body 21. The advantage of this arrangement is that the movement of the shielding structure is manually controlled, which reduces economic costs.

[0046] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
