Description

Technical Field

[0001] This utility model relates to the field of blowing device technology, and in particular to a blowing device for accelerating the cooling of scrap material from a blow molding die. Background Technology

[0002] A blow molding machine is a plastic processing equipment mainly used to blow molten plastic into various shapes and types of plastic bottles or containers using high-pressure airflow. The blow molding die is one of the key components of the blow molding machine, used to mold the molten plastic and give it the desired shape.

[0003] In blow molding dies, baffles serve to position, guide, and support die components. They help ensure precise die alignment and adjustment, improving molding accuracy and stability. To accelerate the cooling process of scrap material, cooling airflow devices can be installed around the die to lower its temperature. However, in existing blow molding die baffles, the two baffles are tightly fitted together, preventing the cooling air from reaching the scrap material underneath. This causes the scrap material to stretch during the peeling process and be directly transported to the filling section, affecting filling efficiency. Therefore, we propose a blow molding die baffle-accelerated scrap cooling airflow device to solve these problems. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a blower device for accelerating the cooling of scrap material in a blow molding die.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a blow molding die baffle for accelerating the cooling of scrap material, comprising a baffle, a mounting frame, a purification cylinder, a mounting plate, a motor, an air supply pipe one, and an air supply pipe two. The mounting frame has symmetrically distributed baffles above it, and the baffles have an arc-shaped air outlet at their center. The purification cylinder is located between the air supply pipe one and the air supply pipe two. An installation block is sleeved on the outer wall of the air supply pipe one. Both ends of the installation block are provided with rotating shafts that are rotatably installed inside the mounting frame. One end of the mounting frame is provided with a motor whose output end is connected to the rotating shaft.

[0006] Preferably, the mounting plate has symmetrically distributed mounting slots inside, and guide rods are provided at both ends of the mounting bracket. Sliding sleeves are embedded inside both ends of the mounting plate, and the lower ends of the guide rods are slidably inserted into the sliding sleeves. The mounting slots are used for the insertion and installation of fasteners, and the guide rods slide through the sliding sleeves, thereby providing longitudinal guidance for the longitudinally moving installation.

[0007] Preferably, the upper end of the mounting plate is provided with a sleeve, and a screw is threaded inside the sleeve. The mounting bracket can be adjusted in height by rotating inside the sleeve via the screw.

[0008] Preferably, the mounting bracket has a bearing seat at its upper end, and the upper end of the screw is rotatably inserted into the bearing seat. The outer wall of the screw has rotating rods arranged in a ring array. When rotating the screw, the rotating rods facilitate the application of rotational force, and the rotational force of the screw acts on the inside of the bearing seat, avoiding the rotational force from acting directly on the mounting bracket.

[0009] Preferably, a flexible hose is provided in the middle section of the second air delivery pipe. The flexible hose allows the second air delivery pipe to bend.

[0010] Preferably, the upper end of the air supply pipe is provided with a fitting seat, the inside of the purification cylinder is provided with a filter screen, and the lower end of the purification cylinder is provided with a fitting head that fits into the fitting seat. The purification cylinder connects to the fitting seat through the fitting head, and the filter screen filters the passing gas.

[0011] Preferably, both the second air supply pipe and the outer wall of the purification cylinder are fitted with internally threaded sleeves, and an externally threaded sleeve is threaded onto the outer wall of the internally threaded sleeve. A limit ring is provided on the outer wall of the internally threaded sleeve. After the externally threaded sleeve is rotated and fitted onto the outer wall of the internally threaded sleeve, it closes the connection by engaging with the limit ring, thus connecting the purification cylinder and the second air supply pipe.

[0012] Preferably, connecting blocks 1 are provided on both sides of the lower end of the baffle, and connecting blocks 2 are symmetrically distributed on the outer wall of the air supply pipe 2. The connecting blocks 1 and 2 are fixed together by bolts. The purification cylinder is connected by connecting blocks 1 and 2, and the connecting blocks 1 and 2 are fixed together by bolts.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model has an arc shape processed in the middle of the baffle, and there will be a circular air outlet between the two baffles. Cooling air can be blown onto the scrap material. The position of the conveying airflow can be adjusted. Because the two baffles of the blow molding machine mold are tightly attached together, the problem of cooling air below the baffle not being able to blow onto the scrap material is avoided. During the peeling process, the processed parts are prevented from being excessively stretched and then directly conveyed to the filling section, ensuring the filling efficiency of the blow molding machine processing.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-5 As shown, the present invention proposes a blow molding die baffle accelerated edge material cooling blowing device, including baffle 1, mounting frame 3, purification cylinder 4, mounting plate 5, motor 6, air supply pipe 1 8 and air supply pipe 2 16. The mounting frame 3 is provided with symmetrically distributed baffles 1. The center of the baffle 1 is provided with an arc-shaped air outlet 2. The outer wall of the air supply pipe 1 8 is sleeved with a mounting block 15. Both ends of the mounting block 15 are provided with rotating shafts 9 rotatably installed inside the mounting frame 3. One end of the mounting frame 3 is provided with a motor 6 whose output end is connected to the rotating shaft 9.

[0023] The mounting plate 5 has symmetrically distributed mounting slots inside. Both ends of the mounting bracket 3 are provided with guide rods 10. Both ends of the mounting plate 5 are embedded with sliding sleeves 11. The lower end of the guide rod 10 is slidably inserted into the sliding sleeve 11.

[0024] A flexible hose 7 is installed in the middle section inside the air supply pipe 216;

[0025] Connecting blocks 1 23 are provided on both sides of the lower end of the baffle 1, and connecting blocks 24 are symmetrically distributed on the outer wall of the air supply pipe 2 16. Connecting blocks 1 23 and connecting blocks 24 are fixed together by bolts 25.

[0026] Based on the implementation steps of Example 1: The two baffle plates 1 of the blow molding machine are tightly attached together. By setting an arc-shaped air outlet 2 at the center of the baffle plate 1, the cooling airflow through the air supply pipe can pass through the air outlet 2 and the baffle plate 1, effectively cooling and shaping the scrap material during the processing. This avoids the situation where the scrap material in the blow molded product is stretched during the peeling process due to insufficient cooling and is directly transported to the filling section, affecting the filling efficiency. During the blow molding process, the cooling effect of the scrap material is significantly improved.

[0027] During use, the baffle 1 connects to the connecting block 24 via the connecting block 1 23 and the outlet 2 of the air supply pipe 2 16. When the motor 6 drives the rotating shaft 9 to rotate, it drives the mounting block 15 to rotate. Through the hose 7, the air supply pipe 2 16 rotates effectively, driving the opening of the air supply pipe to adjust its position, thereby adjusting the delivery position of the cooling airflow. This improves the flexibility of cooling airflow delivery adjustment during processing.

[0028] like Figures 1-5 As shown, compared with Embodiment 1, the blow molding die baffle accelerated edge material cooling blowing device proposed in this utility model further includes: a purification cylinder 4 is provided between the air supply pipe 1 8 and the air supply pipe 2 16.

[0029] A sleeve 12 is provided at the upper end of the mounting plate 5, and a screw 13 is installed inside the sleeve 12 with internal threads.

[0030] The upper end of the mounting bracket 3 is provided with a bearing seat, the upper end of the screw 13 is rotatably inserted into the bearing seat, and the outer wall of the screw 13 is provided with rotating rods 14 arranged in a ring array.

[0031] The upper end of the air supply pipe 8 is provided with a fitting seat 22, the inside of the purification cylinder 4 is provided with a filter screen 20, and the lower end of the purification cylinder 4 is provided with a fitting head 21 that fits into the fitting seat 22.

[0032] Both the air supply pipe 16 and the outer wall of the purification cylinder 4 are fitted with internal threaded sleeves 17. The outer wall of the internal threaded sleeve 17 is threaded with an external threaded sleeve 19. A limit ring 18 is provided on the outer wall of the internal threaded sleeve 17.

[0033] In this embodiment, the gripping screw 14 drives the screw 13 to rotate, and the rotational force of the screw 13 is applied to the bearing seat. When the screw 13 rotates inside the sleeve 12, the longitudinal force of the screw 13 drives the mounting bracket 3 to move longitudinally. At the same time, when the cooling airflow passes through the filter screen 20, the dust in the airflow is intercepted, which avoids the cooling airflow from contaminating the blown bottle products. When cleaning the filter screen 20, it is only necessary to rotate the outer threaded sleeve 19 to disengage from the inner threaded sleeve 17, which facilitates the disassembly and cleaning of the purification cylinder 4.

[0034] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
