Description

Technical Field

[0001] This utility model relates to the field of plastic bottle production technology, specifically to a preform separation and recycling device for injection molding machines on a plastic bottle production line. Background Technology

[0002] An injection molding machine is a device used to produce plastic preforms for the mass production of plastic bottles.

[0003] During the preform production process, 3,000 preforms need to be sampled for customer testing and verification. Since the machines and molds in the factory cannot be operated with a single mold cavity, it is necessary to sample 3,000 preforms of 42g each (i.e., 3,000 molds) under normal operating conditions. Each mold contains 96 preforms (1 preform of 42g and 95 preforms of 43g), requiring a total production of 288,000 preforms. Then, 3,000 preforms of 42g each are selected. This sampling method is inefficient, increases labor costs, and carries the risk of missing preforms. To solve the above problems, this application proposes a preform separation and recycling device for injection molding machines on plastic bottle production lines. Utility Model Content

[0005] To address the technical problems existing in the background art, this utility model proposes a preform separation and recycling device for injection molding machines on a plastic bottle production line. It can simultaneously produce 96 preforms, including one 42g preform and 95 43g preforms. The 42g preforms are positioned at the ends of 12 sets of die heads. After release, the 42g preforms fall onto a discharge hood, which discharges them. This allows for the separation of 42g and 43g preforms, preventing them from mixing, improving sampling efficiency, and reducing labor costs, thus solving the problems mentioned in the background art.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0025] like Figures 1-4 As shown, this utility model proposes a preform separation and recycling device for injection molding machines on a plastic bottle production line, including a robot 1, a COOLPIK injector 2, and a die head 3. The COOLPIK injector 2 is mounted on the robot 1, and the die head 3 is mounted on the lower surface of the COOLPIK injector 2. A discharge conveyor belt 4 is provided below the COOLPIK injector 2, and a discharge outlet 7 is opened on the side wall of the discharge conveyor belt 4. A discharge cover 5 is movably provided in the inner cavity of the discharge outlet 7. The discharge cover 5 is at a 20-degree angle to the horizontal plane, and the end of the discharge cover 5 extends to the bottom of one group of die heads 3. There are a total of 96 die heads 3, and the die heads 3 are distributed in an 8*12 pattern.

[0026] It should be noted that robot 1 drives COOLPIK injection unit 2 to move onto discharge conveyor belt 4 via a robotic arm. After COOLPIK injection unit 2 releases the preform, the preform on die head 3 falls onto discharge conveyor belt 4, where it can be discharged. There are 96 sets of die heads 3, arranged in an 8*12 pattern, which can produce 96 preforms simultaneously. Among them, there is one 42g preform and 95 43g preforms. The 42g preforms are located at the ends of 12 sets of die heads 3. After release, the 42g preform falls onto discharge cover 5, where it can be discharged. This allows for the differentiation of 42g and 43g preforms, preventing them from mixing together, improving sampling efficiency, and reducing labor costs.

[0027] In this embodiment, as Figure 3 and Figure 4As shown, guide seats 6 are welded to both sides of the discharge hood 5. The guide seats 6 are symmetrically distributed. Guide grooves 8 are opened on the surface of each guide seat 6. The guide grooves 8 are slidably connected to the side wall surface of the discharge outlet 7. Guide holes are opened through the surface of the guide seats 6. Guide posts 9 are provided at the positions corresponding to the guide holes in the inner cavity of the discharge outlet 7. The guide posts 9 are inserted into the guide holes.

[0028] It should be noted that the guide seat 6 is slidably connected to the inner wall of the discharge port 7 through the guide groove 8, and the guide post 9 is inserted into the guide hole, which can guide the lifting and lowering of the discharge hood 5.

[0029] In this embodiment, as Figure 3 and Figure 4 As shown, each of the guide posts 9 is fitted with a support spring 10, and the top of the support spring 10 abuts against the lower surface of the guide seat 6.

[0030] It should be noted that the support spring 10 can apply an upward thrust to the guide seat 6, which can lift the COOLPIK ejector 2 and reset the discharge cover 5.

[0031] In this embodiment, as Figure 1 and Figure 4 As shown, one of the sets of mold heads 3 is provided with a downward pressing rod 12 on one side, and the end surface of the discharge cover 5 is provided with a rubber top plate 11. After the COOLPIK ejector 2 descends, the bottom of the downward pressing rod 12 abuts against the surface of the rubber top plate 11.

[0032] It should be noted that when the COOLPIK ejector 2 descends beyond the safety value, the downward push rod 12 will abut against the rubber top plate 11, which can apply a downward thrust to the discharge hood 5. The rubber top plate 11 can act as a buffer.

[0033] The working principle and usage process of this utility model: Robot 1 drives COOLPIK injection unit 2 to move onto discharge conveyor belt 4 via a robotic arm. After COOLPIK injection unit 2 releases the preform, the preform on die head 3 falls onto discharge conveyor belt 4, where it is discharged. Die head 3 has 96 sets arranged in an 8*12 pattern, allowing simultaneous production of 96 preforms, including one 42g preform and 95 43g preforms. The 42g preform is located at the end of the 12th set of die head 3. After release, the 42g preform falls onto discharge cover 5, where it is discharged. This allows for the processing of 42g preforms and... 43g preforms are separated to avoid mixing 42g and 43g preforms, improving sampling efficiency and reducing labor costs. When the COOLPIK ejector 2 descends beyond the safety value, the downward push rod 12 will abut against the rubber top plate 11, which can apply a downward thrust to the discharge cover 5. The guide seat 6 is slidably connected to the inner wall of the discharge port 7 through the guide groove 8. The guide post 9 is inserted into the guide hole, which can guide the rise and fall of the discharge cover 5, allowing the discharge cover 5 to move away from the die head 3 and improve the protection of the die head 3. After the COOLPIK ejector 2 is raised, the discharge cover 5 is supported by the support spring 10, which can reset the discharge cover 5.

[0034] It should be understood that the above-described specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within the protection scope of this utility model. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims or their equivalents.
