Description

Technical Field

[0001] This utility model belongs to the field of plastic filament cooling technology, and in particular relates to a cooling device for recyclable plastic filament drawing. Background Technology

[0002] Recycled plastics are the reuse of plastics, achieved through mechanical shredding. They refer to plastic raw materials obtained by processing waste plastics using physical or chemical methods such as pretreatment, melt granulation, and modification. The plastic granulation process includes the following steps: first, mixing; then, extruding into filaments. The filaments are at a high temperature and require cooling; after cooling, they are dried and granulated. Existing cooling methods include cooling roller cooling, water tank cooling, and air cooling. Traditional water tank cooling typically involves controlling the plastic filaments as they pass through the tank for cooling. However, over time, the tank walls accumulate plastic residues, including leached additives / degradation products, as well as scale and oil. Therefore, regular cleaning of the tank is necessary. Furthermore, existing cooling equipment often requires downtime for maintenance due to the lack of tank partitions, disrupting normal production. Utility Model Content

It achieves segmented cooling control by arranging multiple independent cooling mechanisms along the plastic filament drawing direction; the filament drawing guide mechanism ensures that the plastic filament is immersed below the surface of the cooling liquid; and the lifting mechanism provides vertical adjustment capability, solving the problem of traditional single water tanks requiring shutdown for cleaning.

Detailed Implementation

[0016] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0018] Please see Figure 1 As shown, this utility model is a cooling device for recyclable plastic filament drawing, which includes multiple cooling mechanisms distributed along the gaps of the plastic filament drawing 4 traction path. During operation, any one of the cooling mechanisms can be individually controlled to be activated and deactivated without affecting the activation and deactivation of other cooling mechanisms, thereby achieving continuous and adjustable cooling effect for plastic filament drawing.

[0019] The cooling mechanism includes a cooling water tank 2 filled with cooling water, and a wire drawing guide mechanism 1 for controlling the plastic wire drawing 4 to be immersed below the liquid surface of the cooling water tank 2. The cooling is completed by controlling the plastic wire drawing 4 to be immersed below the liquid surface of the cooling water tank 2 using the wire drawing guide mechanism 1.

[0020] In order to facilitate the activation of the cooling mechanism during use and to clean the cooling water tank 2 of the corresponding cooling mechanism when it is not in use, this application also provides a lifting mechanism 3 for lifting the cooling water tank 2 and controlling the up and down movement of the cooling water tank 2.

[0021] Specifically, after the cooling mechanism is stopped during use, it is convenient to clean the corresponding cooling water tank 2, such as... Figure 2-3, the cooling water tank 2 includes a tank body 20. The bottom side of the tank body 20 is provided with rollers 23, and a U-shaped handle 21 is provided on the side wall of the tank body 20. Then, when the cooling mechanism is deactivated during use, the lifting mechanism 3 is controlled to drive the rollers 23 to fall onto the installation surface, and then the tank body 20 is controlled to move through the U-shaped handle 21 to move the tank body 20 out of the wire drawing guiding mechanism 1, which is convenient for thorough cleaning at this time; and an opening communicating with the inlet and drain pipe 22 is provided at the bottom of the tank body 20, and a hole plug is fitted at the opening. Through the setting of the inlet and drain pipe 22, it is convenient to inject water into the tank body 20 or control the discharge of water in the tank body 20; the inlet and drain pipe 22 is connected to a Y-shaped joint, and the two ends of the Y-shaped joint are respectively connected to a water injection pipe and a drain pipe, and valves are respectively installed on the water injection pipe and the drain pipe.

[0022] In order to facilitate the control of the up and down movement of the tank body 20, the lifting mechanism 3 includes a lifting module 30 and a support plate 31 connected to the top end of the lifting module 30. The support plate 31 supports the outer bottom side of the tank body 20; and the lifting module 30 can be selected from other structures including a lifting column, a scissor lift, etc. that can extend to drive the tank body 20 to move up and down.

[0023] In order to prevent the tank body 20 placed on the support plate 31 from slipping off its upper surface, convex portions A32 and convex portions B33 are respectively provided on the upper surfaces of both ends of the support plate 31, and the tank body 20 on the support plate 31 is limited by the convex portions A32 and convex portions B33.

[0024] Based on the above, in order to facilitate the control of the tank body 20 to move to directly above the support plate 3 under the action of the rollers 23 and then control the lifting module 30 to extend to complete the lifting of the tank body 20, the protruding height of the convex portion A32 is lower than the protruding height of the convex portion B33. That is, during use, the tank body 20 is controlled to be pushed and moved from one side of the convex portion A32 to above the support plate 31 until one side of it abuts against the convex portion B33, as Figure 4 shown, and after the lifting module 30 is fully contracted, the height of the outer bottom side of the tank body 20 is between the convex portion B33 and the convex portion A32.

[0025] In order to facilitate the control of the plastic wire drawing 4 to be immersed below the liquid level of the cooling water tank 2, the provided wire drawing guiding mechanism 1 includes a pair of parallel U-shaped frames 10, and a pair of cross beams 11 are connected between the two U-shaped frames 10; the inner side walls of the two cross beams 11 are both connected with a "channel-shaped" side frame 13 through connecting columns 12. When the corresponding cooling mechanism is activated, the lower part of the side frame 13 is immersed below the liquid level of the cooling water tank 2, and when the corresponding cooling mechanism is activated, the lower part of the side frame 13 is higher than the liquid level in the cooling water tank 2.

[0026] Specifically, two sets of guide rollers and several connecting rods 133 are connected between the side frames 13; the guide roller sets include guide roller one 131 and guide roller two 132; guide roller one 131 is located above guide roller two 132, and the plastic wire 4 enters below the liquid surface through one guide roller set and is then led out from below the liquid surface through another guide roller set.
