The screw rod 21 passes through the fixing seat through hole 30 from the side where the cylindrical rod 22 is located and is transmission-connected to the motor 20. Such a structure will not affect the transmission of the motor 20, nor will it affect the lifting and lowering of the screw rod 21 relative to the slider 5; a fixing block 4 fixedly connected to the base 1 on the first through hole 100 is provided in the groove 10, and the fixing block 4 is fixedly connected to the base 1. The base 1 is fixedly mounted on the equipment, and the fixing block 4 is fixed relative to the device, and the fixing block 4 is provided with a second through hole 40 through which the screw rod 21 passes and a third through hole 41 through which the cylindrical rod 22 passes, that is, one end of the screw rod 21 is transmission-connected to the motor 20, and the other end thereof passes through the second through hole 40, and similarly, one end of the cylindrical rod 22 is fixedly connected to the motor fixing seat 3, and the other end thereof passes through the third through hole 41. When one cylindrical rod 22 is provided, one third through hole 41 is provided, and when two cylindrical rods 22 symmetrically distributed relative to the screw rod 21 are provided, two third through holes 41 are provided and are symmetrically provided relative to the second through hole 40;The second through hole 40 is provided with a slider 5 which is fixedly connected with the fixing block 4 and is sleeved on the screw rod 21 and can perform linear motion relative to the screw rod 21, that is, the slider 5 is slidably arranged on the screw rod 21, and when the screw rod 21 rotates, it performs linear motion relative to the screw rod 21, and the slider 5 is arranged in the second through hole 40 and is fixedly connected with the fixing block 4, and the fixing block 4 is fixedly connected with the base 1, and the base 1 is fixedly connected to the device, so that the slider 5 is also fixed, and its linear motion relative to the screw rod 21 is the rising or falling motion of the screw rod 21 relative to the slider 5 in the synchronous rotation of the screw rod 21 with the motor 20. The rising or falling of the screw rod 21 drives the motor 20, the motor 20 drives the motor fixing seat 3, and the motor fixing seat 3 drives the rising or falling motion of the cylindrical rod 22; the third through hole 41 is provided with a linear bearing 6 with the cylindrical rod 22 as the guide axis, which not only ensures the smooth rising or falling, but also ensures that the rising or falling direction is always in the vertical direction. The top of the screw rod 21 and the cylindrical rod 22 is provided with a lifting plate 7 for lifting. The screw rod 21 is pivoted at the bottom of the lifting plate 7, and the cylindrical rod 22 is fixedly connected to the bottom of the lifting plate 7, so that the lifting plate 7 rises and falls with the lifting of the screw rod 21. The cylindrical rod 22 is fixedly connected to the bottom of the lifting plate 7, which plays a supporting role for it. The screw rod 21 is pivoted at its bottom, which will not affect the synchronous rotation of the screw rod 21 and the rotating shaft of the motor 20, and can drive the lifting of the lifting plate 7. The top of the lifting plate 7 is fixedly connected with a pallet 8 for placing items. The pallet 8 is used to place the materials to be transported. It rises and falls with the lifting of the screw rod 21. Any existing material storage component can be selected to serve as it. The structure is simple, not only can it store materials, but also can be automatically raised to the required position according to the height of the materials to be transported, which is convenient for the material taking mechanism to take materials, avoids frequent manual operations, saves manpower, realizes the automation of feeding, and improves production efficiency. ;

[0025] Further improvements, such as Figures 2 to 4 As shown in , the top of the linear bearing 6 is fixedly connected with a buffer member 60 made of PU which is sleeved on the cylindrical rod 22, so that the impact force received during lifting can be buffered, the strength of the product structure is maintained, and damage during lifting can be avoided.

[0026] Further improvements, such as Figures 1 to 6As shown in the figure, the base 1 includes a bottom plate 11 and two side plates 12 for installation and fixation. The two side plates 12 are fixedly connected on opposite sides of the bottom plate 11 to form a groove 10. The first through hole 100 is arranged on the bottom plate 11. The bottom plate 11 is a flat structure. The side plates 12 are fixedly connected on opposite sides of the bottom plate 11 to form the groove 10. The bottom of the groove 10 is the bottom plate 11. At this time, the first through hole 100 is arranged on it. The two side walls of the groove are the side plates 12. The side plates 12 are used for installation and fixation on the equipment.

[0027] Further improvements, such as Figure 3 and Figure 4 As shown in , the end of the groove 10 is fixedly provided with an annular support plate 101, and the inner wall of the support plate 101 is provided with a step 1010 around it. The bottom surface of the support plate 8 abuts against the step 1010. When the support plate 8 is lowered to the lowest position, the support plate 8 is pressed against the step 1010, and the support plate 101 supports the support plate 8 and prevents the support plate 8 from falling too much and failing to carry materials. At this time, Figure 1 and Figure 2 As shown in , the support plate 101 is also provided with positioning posts 1011 vertically fixedly connected to the support plate 101 at intervals along the circumferential direction. The positioning posts 1011 can further fix the materials placed on the support plate 8 to prevent the products from slipping.

[0028] Further improvements, such as Figures 1 to 5 As shown in the figure, sensors 9 are provided on the base 1 and the motor fixing base 3. After the sensor 9 senses the corresponding information, it will transmit the information to the control mechanism. The control mechanism receives the information and controls the lifting height by manipulating the motor 20. The control mechanism can be implemented by using the existing control circuit, and the sensor 9 can be set according to different sensing requirements, such as setting a sensor for sensing distance on the motor fixing base 3, and setting a pressure sensor for sensing gravity on the base 1.

[0029] Further improvements, such as Figure 1 As shown in the figure, the top of the support plate 8 is detachably connected with a cover plate 80. When the cover plate 80 is used, it can be pressed on the material to prevent it from falling when the material is not in use. It can also play a role in dust prevention. The corresponding connecting parts can be set between each other or not. When it is needed, the cover plate can be directly covered, which is convenient to use.
