Description

Technical Field

[0001] The present invention relates to the technical field of product packaging, and particularly relates to a turntable winding machine that is convenient to adjust and its usage method. Background Technique

[0002] With the increase in labor costs, promoting equipment automation is the trend in the manufacturing industry. Most of the existing plastic film wrapping is completed manually, which not only has low work efficiency and high labor intensity, but also due to uneven operation skill levels, the packaging quality is unstable, affecting product sales. The turntable winding and packing machine drives the goods on the rotating table to rotate through the rotation of the load-carrying turntable, thereby realizing the winding packaging of single-piece goods or a combination of multiple pieces of goods. It is applicable to industries such as building materials, casting, wire and cable, auto parts, and chemicals. After winding and packaging, the goods are more stable, beautiful, and tidy, and can play roles such as waterproofing, dustproofing, anti-scattering, anti-theft, light shielding, and anti-ultraviolet irradiation during long-distance transportation or long-term storage;

[0003] Most of the turntable winding machines on the market currently can complete the film packaging of products. Currently, the product and the winding device are set separately. However, when winding, it is necessary to rotate the product and at the same time rotate the film roll so that the winding film can be evenly wound around the outside of the product. But currently, the rotation of the product and the movement of the winding film are set separately, which will cause deviations in the rotation of the product and the movement of the winding film, and then lead to the winding film not being able to be evenly and stably wound on the product, with poor usage effects. And when the diameter of the product changes, it is not convenient to adjust the moving speed of the winding film roll, and it is more inconvenient to use. Summary of the Invention

In actual setting, several flywheels can continue to be set on the third flywheel 28; the bottom plate 1 is connected to the adjustment frame 30, and the adjustment frame 30 is provided with an adjustment groove 34, and the inner side of the adjustment groove 34 is rotatably connected to an adjustment threaded rod 33, and the adjustment threaded rod 33 is threadedly connected to an adjustment The adjusting block 35 is slidably connected with the adjusting groove 34, so that the adjusting groove 34 can play a role of rotation limiting for the adjusting block 35, so that the adjusting block 35 can move upward or downward along the adjusting threaded rod 33 along the rotation of the adjusting threaded rod 33.

[0035] The placement disc 2 is connected with a positioning device, and the positioning device is used for positioning the object; the positioning device includes a positioning threaded rod 12, and the positioning threaded rod 12 is provided with four groups. The positioning threaded rod 12 is rotatably connected with the placement disc 2, and the placement disc 2 is rotatably connected with a main bevel gear 17, and the positioning threaded rod 12 is connected with a secondary bevel gear 16.

[0036] The mounting frame 18 is connected to an auxiliary plate 24 , the auxiliary plate 24 is connected to a cylinder 23 , and the output shaft of the cylinder 23 is rotatably connected to a pressure plate 25 .

[0037] Start the servo motor 9 to drive the driving gear 10 to rotate. The rotation of the driving gear 10 meshes with the driven gear 7 to make the rotating rod 8 rotate, and then drives the placing disc 2 to rotate. The rotation of the rotating rod 8 drives the transition rod 5 to rotate simultaneously with the rotating rod 8 through the transmission of the transmission sprocket 4 and the transmission chain 42. The rotation of the transition rod 5 drives the fixed wheel 6 to rotate. Through the conduction chain 29, the first flywheel 26 rotates together with the fixed wheel 6, and then the lifting screw rod 21 rotates together with the transition rod 5.

[0038] During actual use, since the spring 37 is stretched, the spring 37 will give a backward pulling force to the sliding rod 38 and the tension frame 31, so that the conduction chain 29 is in a taut state, thus preventing the conduction chain 29 from falling. When the transmission ratio needs to be adjusted, turn the adjustment screw rod 33 to drive the adjustment block 35 to move upward, and then drive the tension frame 31 to move upward, and then pull the right end of the conduction chain 29 to move upward. In actual setting, the position of the tension frame 31 can be set at the rear side of the first flywheel 26 to facilitate the movement of the conduction chain 29. The position shown in the specification drawings is only for facilitating the display of the structure and is not the actual set position. It is hereby specially stated that when the right end of the conduction chain 29 moves upward, at this time, the first flywheel 26, the second flywheel 27 and the third flywheel 28 are all in the rotating turntable. When the right end of the conduction chain 29 moves upward, its components mesh with the second flywheel 27 and gradually fall off from the first flywheel 26, thus completing the meshing connection between the conduction chain 29 and the fixed wheel 6 and the second flywheel 27, thus completing the adjustment of the transmission speed between the transition rod 5 and the lifting screw rod 21, and thus completing the adjustment of the transmission speed between the rotating rod 8 and the lifting screw rod 21, and completing the adjustment of the moving speed of the mounting plate 39 while the rotating speed of the placing disc 2 remains unchanged.

[0039] Turn any positioning screw rod 12 to drive the corresponding positioning block 13 to move. The rotation of the positioning screw rod 12 drives the main bevel gear 17 to rotate, and then makes all the sub-bevel gears 16 rotate together, and then makes all the positioning screw rods 12 rotate simultaneously, and then makes all the positioning blocks 13 move inward to the placing disc 2 at the same time;

[0040] A usage method of a conveniently adjustable turntable winding machine includes the following steps

[0041] S1. Turn the adjustment screw rod 33 according to the requirements of the product to make the conduction chain 29 mesh with the corresponding flywheel;

[0042] S2.

[0043] S3. Turn the contact block 14 to retract the contact block 14 into the positioning block 13, and start the cylinder 23 to drive the pressing plate 25 to move downward to contact the top of the product;

[0044] S4. Start the servo motor 9 to start winding the product.

[0045] Now, the above steps will be described in detail as follows. Turn the adjusting threaded rod 33 according to the requirements of the product so that the transmission chain 29 meshes with the corresponding flywheel; then screw out the contact tube upward, place the product on the placement disc 2, turn the positioning threaded rod 12 to drive all the contact blocks 14 to move together. The contact blocks 14 contact the product and push the product to move, so that the axis of the product and the axis of the placement disc 2 are on the same axis. Then turn the contact block 14 to retract it into the positioning block 13, that is, make the top surface of the contact block 14 located below the top surface of the placement disc 2. In actual setting, the height of the positioning block 13 can be reasonably set to quickly turn the contact block 14. Then start the cylinder 23 to drive the pressing plate 25 to move downward to clamp the product; connect the winding film roll 41 to the mounting plate 39, pull out the free end of the winding film roll 41, and connect it to the product after passing around the guide roller 40 in sequence; start the servo motor 9 to start winding the product; after the winding of the product is completed, the product can be taken off.
