During use, there is a set of specification parts for each product size, and the specification parts cannot be used interchangeably between products of different sizes, so relatively high requirements are imposed on the transmission structure.
[0003] In previous designs, after the equipment has run for a certain period of time, due to various reasons, cumulative errors will occur in the gear transmission. Even a little error between the transmission gears will cause the products on the star disc conveyor to break bottles, thereby increasing the defective rate. In severe cases, it will even affect the use of the equipment and it is necessary to stop the machine for cleaning and restoration. Based on this, the utility model provides a transmission structure that can eliminate the gear transmission clearance. Summary of the Utility Model
[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides a transmission structure. By forming gear two, gear three, and gear four each from two single gears, and connecting the two single gears with a connecting spring, flexible compensation is carried out using the flexibility of the connecting spring to automatically eliminate the clearance, which can ensure that gear one, gear two, gear three, and gear four mesh without skipping teeth, better guarantee the transmission accuracy and stability, significantly improve the overall performance of the equipment, and greatly reduce the defective rate of products, so as to solve the problems occurring in the above-mentioned background art.
[0005] To achieve the above object, the utility model provides the following technical solution: A transmission structure for a high-speed rotary laminating equipment used in the production of small round bottles, including a first synchronous pulley, a second synchronous pulley, a third synchronous pulley, and a fourth synchronous pulley.

[0011] In a preferred embodiment, the gear one and each single gear are made of MC nylon. MC nylon has high tensile strength and rigidity, can maintain good performance under heavy loads, and has excellent wear resistance and self-lubricating properties. Gears made of MC nylon have higher precision, better wear resistance, and quieter.
[0012] Technical effects and advantages of the utility model:
[0013] 1. Gear 2, gear 3 and gear 4 in the utility model are composed of two single gears, which are connected by a connecting spring.

Specific embodiments
[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. 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.
[0022] Referring to the attached drawings of the specification Figures 1-5 , the present utility model provides a transmission structure for a high-speed rotary laminating device used in the production of small round bottles, including the first synchronous pulley 1, the second synchronous pulley 2, the third synchronous pulley 3, and the fourth synchronous pulley 4. A belt is connected between the fourth synchronous pulley 4 and the third synchronous pulley 3, and between the first synchronous pulley 1 and the second synchronous pulley 2. A first gear 5 is provided behind the second synchronous pulley 2. A second gear 6 is meshed on one side of the first gear 5, a third gear 7 is meshed on the top of the first gear 5, and a fourth gear 8 is meshed on one side of the third gear 7;
[0023] Specifically, the transmission ratio between the first synchronous pulley 1, the second synchronous pulley 2, the third synchronous pulley 3, the fourth synchronous pulley 4, the first gear 5, the second gear 6, the third gear 7, and the fourth gear 8 is 5:20:15:5:33:11:22:22, and the number of teeth of the first synchronous pulley 1, the second synchronous pulley 2, the third synchronous pulley 3, the fourth synchronous pulley 4, the first gear 5, the second gear 6, the third gear 7, and the fourth gear 8 are 20T, 80T, 60T, 20T, 132T, 44T, 88T, 88T respectively;
[0024] Both the first synchronous pulley 1 and the third synchronous pulley 3 are fixedly sleeved on the output shaft of the main motor of the high-speed rotary laminating device. The fourth synchronous pulley 4 is fixedly sleeved on the feeding screw of the high-speed rotary laminating device. The second synchronous pulley 2 and the first gear 5 are both fixedly sleeved on the main star plate of the high-speed rotary laminating device. The second gear 6 is fixedly sleeved on the feeding dial shaft of the high-speed rotary laminating device;
[0025] The third gear 7 is fixedly sleeved on the discharge dial shaft of the high-speed rotary laminating equipment, the fourth gear 8 is fixedly sleeved on the rejection dial shaft of the high-speed rotary laminating equipment, the first gear 5 and each single gear 9 are made of MC nylon material. MC nylon has high tensile strength and rigidity, can maintain good performance under heavy loads, and has excellent wear resistance and self-lubricating performance. Therefore, the gears made of MC nylon material have higher precision, are more wear-resistant, and are quieter.
[0026] During use, the main motor on the high-speed rotary laminating equipment for small round bottle production drives the first synchronous pulley 1 and the third synchronous pulley 3 to rotate. The first synchronous pulley 1 transmits power to the second synchronous pulley 2 through a belt. At the same time, the third synchronous pulley 3 transmits power to the fourth synchronous pulley 4 through a belt to provide the feeding power for the feeding screw. The second synchronous pulley 2 drives the first gear 5 to rotate synchronously, thereby driving the feeding dial on the high-speed rotary laminating equipment for small round bottle production to rotate. The first gear 5 then transmits power to the second gear 6 and the third gear 7. The second gear 6 is used to drive the feeding dial on the high-speed rotary laminating equipment for small round bottle production to rotate, and the third gear 7 is used to drive the discharge dial on the high-speed rotary laminating equipment for small round bottle production to rotate. Finally, the third gear 7 transmits power to the fourth gear 8, thereby driving the rejection dial on the high-speed rotary laminating equipment for small round bottle production to rotate. With the above transmission structure, using one main motor can drive the feeding screw, feeding dial, discharge dial, and rejection dial to rotate simultaneously, greatly reducing production costs.
[0027] Refer to the attached Figure 1 、 3 -5. The second gear 6, the third gear 7, and the fourth gear 8 are each composed of two single gears 9. There are two connecting springs 10 connected between the two single gears 9. Arc-shaped grooves 11 are provided on the sides of the two single gears 9 close to each other. A connecting column 12 is fixedly provided inside each arc-shaped groove 11. The two ends of the connecting spring 10 are respectively fixed to the connecting columns 12 on the two single gears 9 for installing and using the connecting spring 10.
[0028] Moreover, one end of the connecting column 12 on each single gear 9 penetrates through the single gear 9 and extends to the outside of the single gear 9.
[0029] Gear two 6, gear three 7, and gear four 8 are all composed of two single gears 9. The two single gears 9 are connected by a connecting spring 10. When one single gear 9 rotates, the other single gear 9 rotates simultaneously to compensate for the gaps generated between gear one 5 and gear two 6, between gear one 5 and gear three 7, and between gear three 7 and gear four 8 with the flexibility of the connecting spring 10, thereby eliminating errors. At the same time, it can also prevent gear one 5 from jumping teeth when meshing with gear two 6, between gear one 5 and gear three 7, and between gear three 7 and gear four 8, thereby improving the smoothness and accuracy of transmission, significantly enhancing the overall performance of the equipment, and greatly reducing the defective rate of products.
[0030] Finally: The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
