Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, and more specifically, to a device for mixing and drawing raw materials for biodegradable plastic woven bags. Background Technology

[0002] Woven bags, also known as snake-skin bags, are a type of plastic bag used for packaging. Their raw materials are generally various chemical plastic raw materials such as polyethylene and polypropylene. Currently, environmental protection is a phenomenon advocated by all enterprises and the public. Therefore, most plastic woven bags use biodegradable materials. They are made by heating, extruding, splitting, and stretching plastic filaments through a plastic drawing machine to form flat filaments, which are then wound up and fed into a circular loom for weaving. After the plastic is extruded from the extrusion box, the filament film needs to be cooled to facilitate subsequent filament drawing.

[0003] However, existing cooling and drawing equipment has many problems. On the one hand, the cooling methods of the cooling devices are relatively simple and uneven, resulting in poor cooling of the plastic filaments and affecting the quality of subsequent drawing, such as uneven thickness of the plastic filaments, which in turn reduces the strength and appearance of the woven bags. On the other hand, during the winding process, there is a lack of effective adjustment mechanisms, making it impossible to ensure that the plastic filaments are evenly wound on the rollers. Moreover, as the winding thickness increases, the conveying path and stress conditions of the plastic filaments change, easily causing uneven stretching of the plastic filaments, further affecting product quality. In addition, existing equipment is difficult to adapt to the production needs of plastic filaments of different diameters, resulting in poor production flexibility.

[0004] Therefore, a biodegradable plastic woven bag raw material mixing and drawing device is proposed. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a biodegradable plastic woven bag raw material mixing and drawing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a biodegradable plastic woven bag raw material mixing and drawing device, including a machine base, a cooling box installed on the machine base, openings on both sides of the cooling box, a water supply component installed at the top inside the cooling box, lifting adjustment components installed at the bottom of both sides of the water supply component, a waste discharge pipe installed at the bottom of the cooling box, a hydraulic lifting platform installed on one side of the cooling box, a lifting plate supported at the top of the hydraulic lifting platform, a moving mechanism installed on the lifting plate, a fixed frame installed at the top of the moving mechanism, and a winding component installed on the fixed frame.

[0007] Preferably, the water supply assembly includes a water supply pipe, a water supply ring, nozzles, and inlets and outlets. The water supply pipe is installed at the top of the cooling tank, and the bottom end of the water supply pipe is connected to the water supply ring. Multiple nozzles are provided on the inner wall of the water supply ring, and the bottom of the water supply ring has an inlet and outlet.

[0008] Preferably, the water supply pipe is connected to a water pump, and the water pump is connected to a cold water source.

[0009] Preferably, the lifting adjustment assembly includes an electric telescopic rod, a top frame, and pulleys. The electric telescopic rod is installed at the bottom of the cooling box, the top frame is installed at the telescopic end of the electric telescopic rod, and the pulleys are installed at the top of the top frame.

[0010] Preferably, the moving mechanism includes a bracket, a first motor, a screw, a guide rod, and a slider. The bracket is mounted on a lifting plate, and a first motor is mounted on one end of the bracket. The output end of the first motor is connected to a screw. Guide rods are provided on both sides of the screw. The slider is sleeved on the screw, and the slider is slidably connected to the guide rods.

[0011] Preferably, the winding assembly includes a second motor and a winding roller, the second motor is mounted on a fixed frame, and the output end of the second motor is coaxially connected to the winding roller.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. Multiple nozzles are installed on the inner wall of the water supply ring in the water supply assembly, which can spray water to cool the passing plastic filaments in a circular manner, improve the uniformity and comprehensiveness of cooling, ensure better cooling effect of plastic filaments, and benefit the subsequent filament drawing quality.

[0014] 2. The height of the top frame can be adjusted by the electric telescopic rod of the lifting adjustment component, which drives the pulley to adjust the height of the plastic wire entering the cooling box. This ensures that the plastic wire remains coaxial with the water supply ring according to the diameter of the plastic wire, thus guaranteeing uniform cooling and enhancing the device's adaptability to different specifications of plastic wire.

[0015] 3. The screw is driven to rotate by the first motor, which moves the slider along the guide rod, causing the fixed frame and winding assembly to shift. This ensures that the plastic filament is evenly wound on the winding roller, and the tension on the plastic filament does not change during the winding process, thereby improving the uniformity of the plastic filament thickness and enhancing product quality.

[0016] 4. The hydraulic lifting platform can be adjusted according to the changes in winding thickness, so that the plastic filament remains horizontal during the conveying process without changing the conveying path length, ensuring uniform force on the plastic filament, and further improving the consistency of the plastic filament thickness.

[0024] 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.

[0025] As attached Figure 1-5 The biodegradable plastic woven bag raw material mixing and drawing device shown includes a machine base 1, a cooling box 2 installed on the machine base 1, and openings 3 on both sides of the cooling box 2. A water supply component 4 is installed at the top inside the cooling box 2, and lifting adjustment components 11 are installed at the bottom of both sides of the water supply component 4. A waste discharge pipe 5 is installed at the bottom of the cooling box 2. A hydraulic lifting platform 6 is installed on one side of the cooling box 2. A lifting plate 7 is supported at the top of the hydraulic lifting platform 6. A moving mechanism 8 is installed on the lifting plate 7. A fixed frame 9 is installed at the top of the moving mechanism 8. A winding component 10 is installed on the fixed frame 9.

[0026] In practice, the filament from the drawing machine outlet on one side of the machine 1 enters the cooling box 2 through the adjacent port 3. It is supported by two lifting and adjusting components 11 within the water supply component 4, and then pulled out through another port 3 to connect with the winding component 10. During the drawing process, the winding component 10 operates, pulling the filament. When the filament enters the cooling box 2, it is cooled by the water spray area in the water supply component 4 before being wound onto the winding component 10. During the winding process, the water supply component 4 can spray water evenly onto the passing plastic filament, improving the uniformity and comprehensiveness of cooling. Furthermore, the moving mechanism 8 at the bottom of the winding assembly 10 operates, causing the plastic filament to be evenly wound onto the winding roller 1002. As the winding thickness increases, the hydraulic lifting platform 6 descends accordingly, ensuring that the plastic filament remains horizontal when it exits, thus maintaining the same conveying path length and ensuring uniform force on the plastic filament. This results in more uniform thickness of the processed plastic filament. The lifting adjustment assembly 11 is used for pre-drawing adjustment to allow for height adjustment based on the diameter of the plastic filament to be drawn, ensuring that the plastic filament is coaxial with the water supply ring 402 as it passes through, thereby improving the uniformity of cooling.

[0027] The water supply assembly 4 includes a water supply pipe 401, a water supply ring 402, a nozzle 403, and an inlet / outlet 404. The water supply pipe 401 is installed at the top of the cooling box 2. The bottom end of the water supply pipe 401 is connected to the water supply ring 402. Multiple nozzles 403 are provided on the inner wall of the water supply ring 402. The bottom of the water supply ring 402 has an inlet / outlet 404.

[0028] The water supply pipe 401 is connected to a water pump, which is connected to a cold water source.

[0029] In practice, cold water is pumped from the water pipe 401 into the water ring 402 by a water pump, and then sprayed out by each nozzle 403, thereby cooling the plastic filaments that coaxially pass through the water ring 402. By cooling in a circular manner, the uniformity of cooling the plastic filaments can be improved.

[0030] The lifting adjustment assembly 11 includes an electric telescopic rod 1101, a top frame 1102, and a pulley 1103. The electric telescopic rod 1101 is installed at the bottom of the cooling box 2. The top frame 1102 is installed at the telescopic end of the electric telescopic rod 1101, and the pulley 1103 is installed at the top of the top frame 1102.

[0031] In practice, the height of the pulley 1103 at the top of the top frame 1102 can be adjusted by extending and retracting the electric telescopic rod 1101, thereby providing height support adjustment for the plastic wire entering the cooling box 2. When the diameter of the plastic wire is changed as needed, the appropriate height adjustment can ensure that the plastic wire remains coaxial with the water supply ring 402, thus facilitating uniform cooling.

[0032] The moving mechanism 8 includes a bracket 801, a first motor 802, a screw 803, a guide rod 804, and a slider 805. The bracket 801 is mounted on the lifting plate 7. The first motor 802 is mounted on one end of the bracket 801. The output end of the first motor 802 is connected to the screw 803. Guide rods 804 are provided on both sides of the screw 803. The slider 805 is sleeved on the screw 803, and the slider 805 is slidably connected to the guide rods 804.

[0033] In specific implementation, the first motor 802 operates, causing the screw 803 to rotate, which in turn allows the slider 805 to move back and forth along the guide rod 804. This causes the fixing frame 9 mounted on the slider 805 to move accordingly, thereby displacing the winding assembly 10. This facilitates the winding assembly 10 in winding the plastic filament, ensuring that the plastic filament is evenly wound onto the winding roller 1002, and that the tension on the plastic filament remains unchanged during the winding process, thus improving the uniformity of the plastic filament thickness.

[0034] The winding assembly 10 includes a second motor 1001 and a winding roller 1002. The second motor 1001 is mounted on the fixed frame 9, and the output end of the second motor 1001 is coaxially connected to the winding roller 1002.

[0035] In practice, the operation of the second motor 1001 enables the roller 1002 to rotate, thereby winding the plastic filament. By changing the operating speed of the second motor 1001, the tension on the plastic filament can be changed, thereby changing the thickness of the plastic filament.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
