Description

Technical Field

[0001] The utility model relates to the field of combined bottle preforms, in particular to a high-speed taking out and cooling device for combined bottle preforms. Background Art

[0002] With the development of industrial technology, domestic and foreign food and beverage manufacturers are increasingly competing fiercely, and have higher requirements for the stability, efficiency, and energy consumption of PET injection molding equipment. The core of high efficiency is reflected in the faster and faster product molding cycle. However, the faster molding cycle will inevitably lead to a reduction in the cooling time of the product in the mold, which will lead to an increase in the temperature of the preform out of the mold.

[0003] In the PET injection molding industry, high preform temperature is a serious technical problem, which mainly leads to the following problems:

[0004] 1. The stress cannot be removed in time, affecting the use of the rear-end bottle blowing;

[0005] 2. The preforms are packed at high temperatures, causing the preforms to be squeezed and deformed, affecting the product appearance and size parameters;

[0006] 3. The temperature of the preform is high. After extrusion, the bottle mouth is prone to deformation or even cracks, affecting the sealing of the product.

[0007] In order to speed up the cooling of the preform, the common practice is to lower the mold cooling water temperature, introduce chilled water at about 12 degrees Celsius to accelerate the molding and cooling of the preform, and introduce a multi-station mold cooling robot to use the same chilled water to cool the outer surface of the preform. However, as the cycle is further compressed, the cooling effect of the above methods is increasingly limited. In summary, the combined preform equipment on the market has the problem of poor cooling effect. Utility Model Content

[0030] Specifically, the following states are presented:

[0031] 1. When in the empty alignment state, please refer to Figure 3-4 , the suction device 4 sucks the preform, the Y-axis driving device 6 drives the suction device 4 to move to the middle position along the negative direction of the Y-axis, the C1-axis driving device 8 drives the suction device 4 to rotate toward the multi-station cooling and conveying device 7, and the X2-axis driving device 10 drives the multi-station cooling and conveying device 7 to operate, so that the vacant cooling station of the multi-station cooling and conveying device 7 is aligned with the station in the suction device 4 that sucks the full preform.

[0032] 2. When in the alignment suction state, the Y-axis driving device 6 drives the suction device 4 to move a certain distance along the negative direction of the Y-axis to the multi-station cooling and conveying device 7, so that a part of the bottle preform enters the vacant cooling station of the multi-station cooling and conveying device 7, and moves a certain distance so that the vacant cooling station of the multi-station cooling and conveying device 7 can smoothly absorb the bottle preform on the suction device 4.

[0033] 3. Following the previous step, please refer to Figure 5-6After the multi-station cooling and conveying device 7 absorbs the preform, the Y-axis driving device 6 drives the absorbing device 4 to move to the middle position along the negative direction of the Y-axis, the C1-axis driving device 8 drives the absorbing device 4 to rotate toward the X1-axis taking-out device 1, and the X2-axis driving device 10 drives the multi-station cooling and conveying device 7 to move, so that the center of the station with the longest cooling time in the multi-station cooling and conveying device 7 is aligned with the center of the embryo placement position of the second rack 9, and the C2-axis driving device 8 drives the multi-station cooling and conveying device 7 to rotate to a horizontal level, and the preform with the longest cooling time is unloaded through program control; after the driving device 2 drives the X1-axis taking-out device 1 to quickly enter the mold along the X-axis direction to absorb the preform, the X1-axis taking-out device 1 quickly retreats and the mold is closed, and after the X1-axis taking-out device 1 is in place along the X-axis direction, the Y-axis driving device 6 drives the absorbing device 4 to move along the positive direction of the Y-axis to approach the X1-axis taking-out device 1, ready to absorb the preform on the cooling station of the X1-axis taking-out device 1, and so on.

[0034] Preferably, the X1-axis extraction device 1 is located between the driving device 2 and the multi-station cooling and conveying device 7. The suction device 4 is located between the X1-axis extraction device 1 and the multi-station cooling and conveying device 7. The entire device has a novel structure, a clever design, strong applicability, and is easy to promote.

[0035] Specifically, with the rapid development of PET injection molding equipment, various manufacturers have a strong demand for high-speed production lines. For this reason, PET production equipment requires a faster cycle while ensuring a high number of cavities. The existing solution is to configure a cooling device with multiple stations on the manipulator that enters and exits the mold. However, due to the large number of mold cavities and the large structure, the manipulator equipped with a cooling device with multiple stations has a large moving part weight, and the time it takes to enter and exit the mold accounts for the entire cycle. Therefore, how to reduce the removal time and ensure the cooling effect of the product is a difficult problem. A combined high-speed bottle embryo removal and cooling device is configured with fewer cooling stations at the front end, making it lighter in weight, so it can ensure rapid entry and exit of the mold to remove the product. A suction device is arranged in the middle, and a cooling device with multiple stations is arranged at the rear end, that is, while the product is quickly taken out of the mold and subsequently transported, the cooling effect of the entire product is guaranteed, and the rear cooling station can be configured according to the maximum spacing of the mold. Cooling stations are arranged at the front and rear ends, which increases the number of cooling stations for the product. Compared with the existing cooling device with multiple stations arranged at the front end, the weight of the fast-moving part of the front end is greatly reduced, and the contradiction between the time occupied by the front end entering and exiting the mold and its own large mass that limits its speed is effectively solved, that is, the product can be quickly taken out while achieving better cooling effect, and provide a strong guarantee for accelerating the injection molding cycle of the product in the next step.
