Description

Technical Field

[0001] The utility model relates to the technical field of clothing processing equipment, specifically to a driving mechanism for a hot air blower heater. Background Art

[0002] The hot air laminating machine is mainly used for waterproof processing of the seams of various protective clothing and outdoor sports products, such as suit raincoats, waterproof shoes and hats, waterproof diving suits, medical protective clothing, etc. Its working principle is that the hot air blower heats up, and then the air pump blows the heat onto the hot sealing tape to make it reach the melting point. Finally, the upper and lower rubber wheels close and rotate to make the tape and the fabric closely combined.

[0003] When laminating and bonding fabrics, the hot air blower is in a continuous heating and air outlet state. Therefore, in order to prevent workers from being scalded when changing fabrics, mechanical mechanisms such as cylinders, motors or rockers are generally used to move the air outlet pipe of the hot air blower away. For example, the Chinese utility model patent CN213675513U (publication date: July 13, 2021) discloses a sealing machine based on hot air seams, which uses a horizontal driving cylinder to drive the spray gun to rotate close to or away from the dynamic pressure roller and the static pressure roller. Although this structure realizes the automatic approach and separation of the air outlet pipe of the hot air blower, since it only moves in one direction, the actual avoidance effect is limited, and it is still easy to scald workers.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figure 1 , the driving mechanism of the hot air blower heater, including an adjusting bracket 1, a positioning bracket 2 installed on the adjusting bracket 1, and a hot air duct 3 installed on the positioning bracket 2. The positioning bracket 2 includes an L-shaped bracket 4 connected to the adjusting bracket 1 and a mounting block 5 connected to the L-shaped bracket 4. A pipe sleeve 6 is provided on the mounting block 5, and the hot air duct 3 is fixedly installed on the pipe sleeve 6. The bottom end of the hot air duct 3 is fixedly connected with an air outlet nozzle 7. On the L-shaped bracket 4, there are a first connecting rod 8 and a second connecting rod 9 that are parallel to each other and one end of which is hinged to the L-shaped bracket 4. The other ends of the first connecting rod 8 and the second connecting rod 9 are respectively hinged to the back of the mounting block 5. The four hinge points of the first connecting rod 8 and the second connecting rod 9 are connected in sequence to form a parallelogram. A driving block 81 is fixedly connected to the back of the first connecting rod 8. A cylinder bracket 10 is fixed to the back of the L-shaped bracket 4, and a driving cylinder 11 is hingedly installed on the cylinder bracket 10. A pin shaft 12 passing through the end of the telescopic rod of the driving cylinder 11 is provided on the driving block 81. The present utility model adopts a parallelogram link mechanism to cooperate with the driving cylinder 11 to drive the hot air duct 3 to swing and feed. When applied to an automatic control program, only the control program design for the driving cylinder 11 needs to be carried out, and the displacement of the hot air duct 3 can be realized simultaneously in the horizontal and vertical directions. The moving space is large, and the control operation is simple and convenient; compared with the vertical and horizontal slide rail structure, the present utility model can save driving components, has a low equipment cost, and is convenient for installation and maintenance; due to the stability of the parallelogram connection mechanism, the hot air sealing pipe keeps the angular attitude unchanged during the movement, ensuring the accuracy of the air outlet direction.

Specifically, as Figure 3 shown, the buffer column 15 and the vertical plate of the L-shaped bracket 4 are located in the same vertical plane. When the driving cylinder 11 drives the hot air duct 3 to move down and feed in place, the buffer column 15 abuts against the side of the L-shaped bracket 4 to play a buffering and limiting role, avoiding the hot air duct 3 from overfeeding and hitting the processing platform.

[0021] Further, a cylinder fixing block 16 is hinged to the cylinder bracket 10. A round hole is provided at the center of the cylinder fixing block 16. The cylinder body of the driving cylinder 11 is fixedly installed on the cylinder fixing block 16, and its telescopic rod extends out from the round hole.

Specifically, the up-and-down slide rail 17 can be fixedly installed on the frame of the hot air laminating machine. The spatial position of the L-shaped frame 4, that is, the position of the hot air pipe 3, can be adjusted through the up-and-down slider 20, the left-and-right slider 21, and the front-and-back slider 22, which is beneficial to adapting to the laminating and heating of different protective clothing products.

The positions of the up-and-down slider 20, the left-and-right slider 21, and the front-and-back slider 22 can be adjusted by the adjusting screws 23.
