Packaging foam is a type of polymer material formed by a large number of gas micropores dispersed in solid plastic. It has the characteristics of light weight, heat insulation, sound absorption, and shock absorption. In order to improve the moisture-proof performance of packaged products, it is necessary to improve the moisture-proof performance of packaging materials. Since foam products are close to the outer shell of the product, the moisture-proof performance of foam products needs to be improved. Generally, the surface of foam products is covered with a film to improve its moisture-proof performance.

DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0022] Example: Figure 1-4 As shown, a height adjustment mechanism of a laminating machine equipped with a reduction motor comprises a base 1, a roller conveyor 2 is fixedly installed on the top of the base 1, a laminating roller 4 is arranged above the roller conveyor 2, a mounting frame 3 is fixedly connected to the front and rear sides of the top of the base 1, a connecting block 5 is slidably connected inside the mounting frame 3, and the two connecting blocks 5 are rotatably connected to the front and rear ends of the laminating roller 4 respectively, a first threaded rod 7 is fixedly connected to the top of the connecting block 5, and the first threaded rod 7 penetrates to the top of the mounting frame 3, a threaded sleeve 18 is rotatably connected to the top of the mounting frame 3, and the threaded sleeve 18 is threadedly connected to the first threaded rod 7, a driven pulley 11 is fixedly connected to the rear end of the laminating roller 4, and the driven pulley 11 is connected to the driving pulley 12 through a belt, a reduction motor is installed at the front end of the driving pulley 12, and the reduction motor is arranged inside the base 1, a pair of limiting columns 6 are fixedly connected to the inside of the mounting frame 3, and the limiting columns 6 pass through the connecting block 5;

[0023] The packaging foam moves on the roller conveyor 2. When it passes through the coating roller 4, the reduction motor works to drive the active pulley 12 to rotate. The active pulley 12 rotates the driven pulley 11 through the belt, and then the coating roller 4 rotates. The coating roller 4 operates on the packaging foam to make the film adhere to the surface of the packaging foam. When coating packaging foam of another specification, the threaded sleeve 18 is rotated to improve the application range of the laminating machine.

[0024] Specifically, Figure 1 and Figure 2 As shown, the top of the threaded sleeve 18 is fixedly connected to a driven gear 8, the outer side of the driven gear 8 is meshedly connected to a driving gear 9, a motor 10 is installed on the top of the driving gear 9, and the motor 10 is fixedly connected to the top of the mounting frame 3. The motor 10 drives the driving gear 9 to rotate, and the rotating driving gear 9 causes the threaded sleeve 18 to rotate through the driven gear 8.

[0025] Specifically, Figure 3As shown, a mounting groove 17 is provided at the rear end of the base 1, and a second threaded rod 15 is rotatably connected inside the mounting groove 17. The second threaded rod 15 is a bidirectional threaded rod, and a pair of movable blocks are threadedly connected to the outer side of the second threaded rod 15, and the movable blocks are slidably connected inside the mounting groove 17. An adjusting wheel 14 is rotatably connected to the rear end of the movable block, and the belt passes through the adjusting wheel 14. By rotating the second threaded rod 15, the movable block moves along the mounting groove 17, and then the distance between the two adjusting wheels 14 is adjusted, and then the tension of the belt can be adjusted, so that there is sufficient friction between the belt and the driving pulley 12 and the driven pulley 11 to avoid slipping and affecting the normal operation of the equipment.

[0026] Specifically, Figure 3 As shown, a handwheel 16 is installed on the rear side of the base 1, and the front end of the handwheel 16 is connected to one end of the second threaded rod 15 through a reversing mechanism. The reversing mechanism is a pair of mutually meshing bevel gear sets. When the handwheel 16 is rotated, the torsional force is transmitted through the mutually meshing bevel gear sets, thereby driving the second threaded rod 15 to rotate.

[0027] Specifically, Figure 3 As shown, the rear side of the base 1 is rotatably connected with two sets of fixed wheels 13, and the belt passes through the fixed wheels 13. The two sets of fixed wheels 13 are respectively arranged on the upper and lower sides of the adjusting wheel 14. The fixed wheels 13 are used to fix the wrap angle between the belt and the driving pulley 12 or the driven pulley 11 to ensure that there is sufficient friction between the belt and the driving pulley 12 or the driven pulley 11.

[0028] Working principle: The packaging foam moves on the roller conveyor 2. When it passes through the film-coating roller 4, the reduction motor drives the driving pulley 12 to rotate. The driving pulley 12 rotates the driven pulley 11 through the belt, and then the film-coating roller 4 rotates. The film-coating roller 4 works on the packaging foam to make the film adhere to the surface of the packaging foam. When filming packaging foam of another specification, the motor 10 drives the driving gear 9 to rotate. The rotating driving gear 9 rotates the threaded sleeve 18 through the driven gear 8. The threaded sleeve 18 drives the first threaded rod 7 to move through the thread, and then the connecting block 5 moves along the limit column 6 to adjust the height of the film-coating roller 4 to adapt to packaging foams of different specifications.

[0029] During the adjustment of the height of the coating roller 4, the hand wheel 16 is turned to transmit the torsional force through the meshing bevel gear set, thereby driving the second threaded rod 15 to rotate the hand wheel 16, and the torsional force is transmitted through the meshing bevel gear set, thereby driving the second threaded rod 15 to rotate, so that the movable block moves along the mounting groove 17, thereby adjusting the distance between the two adjusting wheels 14, and then the tension of the belt can be adjusted, so that there is sufficient friction between the belt and the driving pulley 12 and the driven pulley 11 to avoid slipping and affecting the normal operation of the equipment.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
