Technical Field
[0001] This utility model belongs to the field of film edge cutting and guiding technology, and in particular relates to an edge material guiding and collecting device for a casting machine. Background Technology
[0002] Casting machines, as a common type of thermoplastic processing equipment, occupy an important position in the blow molding industry due to their simple structure and small footprint. During the production process of a casting machine, according to the viscosity principle of fluid mechanics, the melt resistance at the edge of the film is relatively large, which makes it difficult to control the thickness of the film edge after stretching and forming by the cooling rollers. In order to ensure neat winding, the edge needs to be cut off.
[0003] Currently, small rollers are typically used to collect scrap from the edges of casting machines, but this method has significant drawbacks. Due to the winding tension, the collected scrap tends to clump together, causing considerable trouble for subsequent recycling work, increasing recycling difficulty and costs, reducing production efficiency, and hindering the effective utilization of resources and the smooth operation of the production process.
[0004] Therefore, it is essential to invent a material guide and collection device for a casting machine. Utility Model Content

[0023] As attached Figure 1 To be continued Figure 3 As shown:
[0024] This utility model provides an edge material guiding and collecting device for a casting machine, comprising a worktable 1, a support 2, a centrifugal fan 3, a guide seat 4, a support frame 5, an airflow guide cylinder 6, a fixed wheel 7, a chute 8, a slide seat 9, an adjusting wheel 10, a lead screw 11, and a handwheel 12. The worktable 1 is fixedly installed above the support 2. The centrifugal fan 3, the guide seat 4, and the support frame 5 are sequentially fixedly installed on the worktable 1. The airflow guide cylinder 6 is installed on the centrifugal fan 3. The fixed wheel 7 is rotatably installed on the lower inner side of the support frame 5. The chute 8 is symmetrically arranged on both sides above it. A slide seat 9 is slidably installed in each chute 8. An adjusting wheel 10 is rotatably installed between two slide seats 9. The output end of a servo motor fixedly installed on one slide seat 9 is connected to one end of the adjusting wheel 10. The other slide seat 9 is connected to the lead screw 11 rotatably installed in the chute 8. A handwheel 12 is fixedly installed on the upper end of the lead screw 11.
[0025] Furthermore, a guide seat 4 is fixedly installed at one end of the upper part of the workbench 1, consisting of a vertical plate and a guide cylinder. The vertical plate is made of high-strength aluminum alloy, and its lower end is fixedly connected to the workbench 1 by bolts to ensure the stability of the connection; the upper end is welded and fixed with a guide cylinder, which is made of smooth stainless steel with rounded corners at both ends. This design can effectively reduce the friction and resistance of the film edge material when it enters the guide cylinder, avoid edge material jamming, and ensure that the edge material can smoothly enter the subsequent conveying stage.
[0026] Furthermore, the guide seat 4 and the airflow guide tube 6 installed on the centrifugal fan 3 are positioned opposite each other, and the distance between them is precisely designed to ensure smooth airflow connection. The support frame 5 is located between the airflow guide tube 6 and the guide seat 4, serving as stable support and transition guidance. The support frame 5 is welded from Q235 steel, and its structure has been mechanically optimized to withstand the external forces generated during the operation of the device, while not affecting the airflow and the conveying path of the edge material.
[0027] Furthermore, the airflow guide cylinder 6 consists of an airflow receiving cylinder 61, an inlet pipe 62, a tapered pipe 63, an outlet pipe 64, and an air inlet 65. All components are made of seamless steel pipe or polyethylene, with smooth inner walls and integral connections to ensure airtightness. The airflow receiving cylinder 61 is used to receive the airflow generated by the centrifugal fan 3, and the air inlet 65 located below it is fixedly connected to the outlet of the centrifugal fan 3 via a sealing flange, ensuring stable airflow delivery.
[0028] Furthermore, the diameter of the airflow receiving cylinder 61 is designed to be larger than that of the inlet pipe 62 and the outlet pipe 64, with the airflow receiving cylinder 61 having a diameter of 300 mm and the inlet pipe 62 and outlet pipe 64 having diameters of 200 mm. One end of the inlet pipe 62 is designed with a flared end, with the flared opening angle being 60°. This end is located near the fixed wheel 7 and the adjusting wheel 10, facilitating the smooth introduction of film edge material into the airflow receiving cylinder 61. This diameter difference and flared opening design can utilize the pressure difference generated by the change in airflow velocity to enhance the adsorption and conveying capacity of the edge material.
[0029] Furthermore, the airflow receiving cylinder 61 is connected to the conical opening of the conical tube 63, and the conical tube 63 and the discharge pipe 64 are also integrally connected. The taper of the conical tube 63 is calculated to be 1:5, which allows the airflow to gradually accelerate during the flow process, improving the conveying efficiency of the edge material. The discharge pipe 64 is located away from the fixed wheel 7 and the adjusting wheel 10, and is used to convey the edge material to the designated collection position, ensuring a smooth edge material conveying path.
[0030] Furthermore, after the centrifugal fan 3 starts, the generated airflow enters the airflow receiving cylinder 61 through the air inlet 65. Because the airflow receiving cylinder 61 has a large diameter, the airflow velocity decreases and the pressure increases at this point. As the airflow flows towards the conical pipe 63 and the outlet pipe 64, the airflow velocity increases due to the gradually decreasing pipe diameter, creating a pressure gradient. This pressure change facilitates the smooth transport of the film edge material along the pipes, completing the edge material collection process.
[0031] Working principle:
[0032] First, the film scrap generated during the casting machine production process is cut and guided through the guide tube of the guide seat 4. The rounded corners at both ends of the guide tube reduce the resistance of the scrap. Then, the scrap is conveyed between the fixed wheel 7 and the adjusting wheel 10. The adjusting wheel 10 is driven to rotate by a servo motor, working in conjunction with the fixed wheel 7 to traction and guide the scrap, ensuring that it accurately enters the inlet pipe 62 of the airflow guide tube 6. Simultaneously, the position of the slide 9 in the slide groove 8 can be adjusted by rotating the screw 11 via the handwheel 12, thereby adjusting the height of the adjusting wheel 10 to accommodate film scraps of different thicknesses and materials.
[0033] After the centrifugal fan 3 starts, the generated airflow enters the airflow receiving cylinder 61 through the air inlet 65. Since the diameter of the airflow receiving cylinder 61 is larger than that of the inlet pipe 62, the airflow velocity decreases and the pressure increases at this point, forming a stable airflow environment. The trumpet-shaped end design of the inlet pipe 62 further optimizes the introduction effect of the edge material, allowing the edge material to be smoothly carried by the airflow.
[0034] As the airflow flows into the conical tube 63, its diameter gradually decreases. According to Bernoulli's principle, the airflow velocity gradually increases and the pressure gradually decreases, creating a pressure gradient from the airflow receiving cylinder 61 to the discharge pipe 64. This pressure gradient generates airflow power that propels the edge material forward. After being accelerated through the conical tube 63, it is finally transported to the designated collection position through the discharge pipe 64, completing the edge material guidance and collection process. This entire process utilizes airflow power instead of the traditional roller winding method, effectively avoiding the problem of edge material clumping and improving the convenience and efficiency of edge material recycling.
[0035] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
