[0027] A rotary cutting assembly method for an injection-molded bottle body, comprising the rotary cutting assembly system for an end cap of an injection-molded bottle body;

[0028] The method comprises the following steps:

[0029] Step S1, bottle body injection molding: the bottle body is injection molded by an injection molding machine, the injection molded bottle body includes a bottle body and a port, and a tip portion is formed at the port; after the injection molding is completed, the bottle body of the bottle body is grabbed on the injection molding machine by an injection molding material picking component, and then placed on the injection molding conveying component after being turned over, and the injection molding conveying component is used to convey the turned bottle body toward the conveying mechanism;

[0030] Step S2, rotary cutting positioning: the conveying mechanism conveys the bottle body toward the first positioning mechanism, the first positioning mechanism positions the bottle body on the conveying mechanism for the first time, and after positioning, the bottle body is clamped by the first clamping mechanism, and after clamping, it is lifted toward the rotary cutting positioning plate, and then the rotary cutting limiting step and the rotary cutting positioning groove are used to limit and position the bottle body so that the port is located below the rotary cutting tool module;

[0031] Step S3, end cap peeling: after positioning the bottle body, the peeling transverse shift module drives the peeling drive module and the peeling tool module to move toward the port, the peeling drive module is used to drive the peeling tool module to rotate around the port, and the peeling tool module performs circumferential cutting on the tip of the port, so that the tip is separated from the bottle body; during the peeling tool module cutting process, when the peeling blade moves toward the port and contacts the port, the floating cutter rotates with the shaft element, so that the cutting portion is inserted into the port, and under the action of the peeling transverse shift module, the peeling portion contacts the port, and the peeling drive module drives the floating cutter to rotate, first the peeling portion opens a pre-cut blade and then cuts through the cutting portion;

[0032] Step S4, secondary positioning end cap assembly: after completing the rotary cutting of the tip, the first clamping mechanism grabs and lowers the bottle body and puts it back on the conveying mechanism. The conveying mechanism conveys the bottle body toward the second positioning mechanism. The second positioning mechanism positions the bottle body. After positioning, the bottle body is clamped and fixed by the second clamping mechanism. Then, the end cap is assembled at the port after the ring cutting by the end cap assembly mechanism. After completing the end cap assembly, the second clamping mechanism puts the bottle body back to the conveying mechanism for transportation.

[0033] The beneficial effects of the present invention are:

[0034] Compared with the existing plastic bottle injection molding assembly, the present invention significantly improves the efficiency and accuracy of the bottle production process through integrated and automated design, and realizes the full chain of automated operation from injection molding to end cap assembly. Through the close cooperation between the injection molding machine and the injection molding transfer mechanism, the bottle body can be immediately grasped and transferred after injection molding, avoiding the time delay and error of manual operation, and greatly shortening the production cycle. At the same time, the linkage operation of the conveying mechanism, the positioning mechanism and the clamping mechanism ensures the high-speed and stable transmission of the bottle body between each process, and the overall production efficiency is significantly improved. The rotary cutting mechanism can accurately perform circular cutting on the bottle body port to ensure that the incision is flat and the size is consistent, which is convenient for subsequent assembly. In addition, the first and second positioning mechanisms effectively prevent the deviation and shaking of the bottle body during the processing process, further improving the processing accuracy. The traditional bottle body processing production line requires a large number of workers to participate in multiple links such as injection molding material collection, transportation, positioning, clamping and assembly, which is not only labor-intensive, but also has high labor costs. The present invention significantly reduces manual intervention and reliance on operators through a highly automated design, effectively alleviating the labor shortage problem while reducing the company's labor costs. The end cap assembly mechanism automatically and accurately assembles the end cap to the port after ring cutting, eliminating the tediousness and errors of manual assembly, improving assembly efficiency and consistency, and reducing labor costs. The present invention is highly automated and continuous throughout the entire process, from bottle positioning, clamping and conveying, rotary cutting to end cap assembly, reducing waiting time and manual intervention in the intermediate links, and significantly improving overall production efficiency and capacity.

[0035] The ingenious design of the rotary cutting positioning plate of the rotary cutting mechanism of the present invention combined with the rotary cutting limit step and the positioning groove ensures the precise positioning of the bottle body during the rotary cutting process, effectively prevents the problem of uneven cutting caused by position deviation, and ensures the stability of product quality. At the same time, the introduction of the rotary cutting limit step provides a reliable physical limit for the bottle body, further enhances the safety of the processing process, and reduces the operational risk. The use of the rotary cutting transverse movement module realizes the high-precision linear motion control of the rotary cutting drive module and the tool module, ensuring the accuracy of the cutting path. This design not only simplifies the operation process, but also significantly improves the production efficiency, making the entire rotary cutting process smoother and more efficient. The rotary cutting drive module drives the rotary cutting tool module to perform circumferential cutting around the bottle body port, realizing the precise separation of the complex shape port structure. This circumferential cutting method not only retains the overall integrity of the bottle body, but also significantly reduces the material loss during the cutting process and improves the resource utilization rate. At the same time, the high-precision operation of the rotary cutting tool ensures the smoothness and flatness of the incision, which is convenient for the subsequent assembly of the upper end cover. The present invention not only improves the quality and efficiency of product processing, but also enhances the safety and stability of the equipment, providing strong support for the automation and intelligent development of the bottle processing industry.

[0036] The rotary cutting tool module of the present invention realizes the precise rotary cutting operation of the workpiece port through the synergistic effect of the precisely constructed cutter seat, floating cutter and cutter support element. One end of the cutter seat is firmly connected to the rotary cutting drive module to ensure the stability and reliability of power transmission; the cutter floating groove designed at the other end and its built-in rotating shaft element provide a flexible rotation platform for the floating cutter. The floating cutter not only optimizes the cutting path through the combination of the cutting part and the rotary cutting part, but also reduces the resistance and vibration during the cutting process, effectively extending the service life of the tool. When the rotary cutting blade gradually approaches and contacts the workpiece port, the floating cutter can adaptively rotate around the rotating shaft element as the center to ensure that the cutting part is accurately inserted into the port, which is convenient for subsequent cutting. Under the precise control of the rotary cutting transverse movement module, the rotary cutting part fits tightly with the port, and cooperates with the rotating power of the rotary cutting drive module. The rotary cutting part first opens a pre-cut blade. This process effectively reduces the impact force during direct cutting and protects the workpiece and the tool from damage. Subsequently, the cutting part completes the cutting action in a smooth and efficient manner, and the entire rotary cutting process is smooth and efficient, ensuring the smoothness and dimensional accuracy of the processed surface. The present invention not only greatly improves production efficiency and processing quality, but also reduces maintenance costs and operating risks through its flexibility and durability design.

[0037] The rotary cutting assembly method of injection-molded bottles significantly improves the efficiency and accuracy of bottle processing and assembly through integrated system design and refined operation steps. The whole process from bottle injection molding to end cap assembly is automated, reducing manual intervention and greatly improving production efficiency. The cooperation between the injection molding material collection component and the flipping mechanism ensures that the bottle can quickly and accurately enter the subsequent processing process. The use of a dual positioning mechanism (the first positioning mechanism and the second positioning mechanism) and a high-precision clamping mechanism ensures the stability and accuracy of the bottle during rotary cutting and assembly. The design of the rotary cutting limit step and the rotary cutting positioning groove further improves the position accuracy of the rotary cutting operation and avoids material waste and defective products. The rotary cutting tool module combines the rotary cutting transverse movement module with the rotary cutting drive module to achieve precise circumferential cutting of the tip of the bottle port. The design of the floating cutter can automatically adjust the angle when contacting the port to ensure that the cutting part is smoothly inserted and effectively cut, which not only protects the bottle structure from damage, but also improves the cutting quality. After the peeling is completed, the second positioning mechanism and the second clamping mechanism are used to reposition and fix the end cap, thereby ensuring the accuracy of the end cap assembly. The introduction of the end cap assembly mechanism enables the end cap to be installed quickly and stably, effectively improving the overall quality and sealing performance of the product. The present invention is not only suitable for injection-molded bottles of specific specifications, but its modular design also facilitates adjustment and optimization according to production needs, providing a flexible solution for the processing of bottles of different sizes and shapes, and enhancing the adaptability and scalability of the production line.

[0088] Step S3, end cap peeling: after positioning the bottle body, the peeling transverse shift module drives the peeling drive module and the peeling tool module to move toward the port, the peeling drive module is used to drive the peeling tool module to rotate around the port, and the peeling tool module performs circumferential cutting on the tip of the port, so that the tip is separated from the bottle body; during the peeling tool module cutting process, when the peeling blade moves toward the port and contacts the port, the floating cutter rotates with the shaft element, so that the cutting portion is inserted into the port, and under the action of the peeling transverse shift module, the peeling portion contacts the port, and the peeling drive module drives the floating cutter to rotate, first the peeling portion opens a pre-cut blade and then cuts through the cutting portion;

[0089] Step S4, secondary positioning end cap assembly: after completing the peeling of the tip, the first clamping mechanism 5 grabs and lowers the bottle body and puts it back on the conveying mechanism 3. The conveying mechanism 3 conveys the bottle body toward the second positioning mechanism 7. The second positioning mechanism 7 positions the bottle body. After positioning, the bottle body is clamped and fixed by the second clamping mechanism 8, and then the end cap is assembled at the port after the ring cutting by the end cap assembly mechanism 9. After completing the end cap assembly, the second clamping mechanism 8 puts the bottle body back to the conveying mechanism 3 for conveying.

[0090] The rotary cutting assembly method of the injection-molded bottle body significantly improves the efficiency and accuracy of bottle body processing and assembly through integrated system design and refined operation steps. The whole process from bottle body injection molding to end cap assembly is automated, reducing manual intervention and greatly improving production efficiency. The cooperation between the injection molding material taking component 21 and the flipping mechanism ensures that the bottle body can quickly and accurately enter the subsequent processing process. The use of a dual positioning mechanism (a first positioning mechanism 4 and a second positioning mechanism 7) and a high-precision clamping mechanism ensures the stability and accuracy of the bottle body during rotary cutting and assembly. The design of the rotary cutting limit step and the rotary cutting positioning groove further improves the position accuracy of the rotary cutting operation and avoids material waste and defective products. The rotary cutting tool module combines the rotary cutting transverse movement module with the rotary cutting drive module to achieve precise circumferential cutting of the tip of the bottle body port. The design of the floating cutter can automatically adjust the angle when contacting the port to ensure that the cutting part is smoothly inserted and effectively cut, which not only protects the bottle body structure from damage, but also improves the cutting quality. After the peeling is completed, the second positioning mechanism 7 and the second clamping mechanism 8 are used to reposition and fix the end cap, thereby ensuring the accuracy of the end cap assembly. The introduction of the end cap assembly mechanism 9 enables the end cap to be installed quickly and stably, effectively improving the overall quality and sealing performance of the product. The present invention is not only suitable for injection-molded bottles of specific specifications, but its modular design also facilitates adjustment and optimization according to production requirements, providing a flexible solution for the processing of bottles of different sizes and shapes, and enhancing the adaptability and scalability of the production line.

It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
