Description

TECHNICAL FIELD

[0001] The utility model relates to extruder cooling technical field, concretely is a kind of extruder cooling device for producing PPO profile. BACKGROUND

[0002] PPO profile extruder is the machine that material can be fully plasticized, uniformly mixed and formed through die by the pressure and shear force generated by screw rotation.

[0003] In the extrusion process, the profile extruded from the die of extruder needs to be rapidly cooled for storage. Since water has large specific heat capacity, it is easy to exchange heat with hot profile. Moreover, water has stable chemical properties and can be recycled, so the cooling of profile is mainly in the form of water cooling.

[0004] In the prior art, since cooling water needs to be continuously circulated, the water level in the cooling tank is unstable and easily fluctuates due to fluctuations in water inflow and outflow. Once the water level is lower than the height of the profile, the profile is likely to be exposed to the water surface, affecting the heat exchange efficiency and making the profile not completely cooled, which is prone to deformation in the subsequent conveying process.

[0024] This utility model embodiment provides an extruder cooling device for producing PPO profiles, such as... Figures 1-3 As shown, the device includes a cooling tank 1. The cooling tank 1 has an inlet 13 and an outlet 14 at its front and rear ends for water inlet and outlet, respectively. The inlet 13 and outlet 14 are connected to an inlet pipe and a drain pipe. The water circulation system is existing technology. Profiles enter the cooling tank 1 from the end near the inlet 13 and exit from the end near the outlet 14.

[0025] like Figure 2 As shown, profile support mechanisms are provided at both ends of the cooling tank 1. Each profile support mechanism includes a support groove 2, two sets of base plates 3, sliding rods 4, guide sleeves 5, and floats 6. Two guide sleeves 5 are respectively located on the sides of the cooling tank 1. The sliding rods 4 slide vertically onto the guide sleeves 5. The base plates 3 and floats 6 are sequentially located at the bottom of the sliding rods 4. The two sides of the support groove 2 are connected to the two base plates 3. The bottom of the support groove 2, which supports the profile, is lower than the floats 6. When the floats 6 float on the water surface, the profile supported on the support groove 2 is completely submerged.

[0026] The support trough 2 is set to be floating. As the water level in the cooling tank 1 fluctuates, the float 6 can rise or sink accordingly, so that the profile in the support trough 2 is always below the water surface.

[0027] like Figure 2 As shown, since different profiles have different cross-sectional sizes, in order to achieve the best cooling effect for different profiles, it is necessary to adjust the height of the support groove 2. The base plate 3 is provided with an adjustment component for adjusting the height of the support groove 2.

[0028] like Figure 2 As shown, the adjustment assembly includes guide rods 8 and adjusting screws 9. Each set of profile support mechanisms is equipped with three guide rods 8 and one adjusting screw 9. Adjusting plates 7 are provided on both sides of the support groove 2. The guide rods 8 and adjusting screws 9 are vertically mounted on the adjusting plates 7. The guide rods 8 pass through the base plate 3 and slide to fit it. The bottom end of the adjusting screw 9 is pivotally connected to the adjusting plate 7, and the upper section of the adjusting screw 9 passes through the base plate 3 and is threaded to it. The height of the support groove 2 is adjusted by rotating the adjusting screw 9 to place the profile in the optimal underwater position.

[0029] To achieve diverse cooling methods, such as in winter when the temperature is low and the water flow in the cooling tank 1 is small with minimal water level fluctuations, cooling can be achieved by fixing the height of the support tank 2. Vertically spaced positioning holes 10 are provided on the slide rod 4, and a positioning bolt 11 corresponding to the positioning hole 10 is threaded onto the guide sleeve 5. During adjustment, after sliding the slide rod 4 to the specified height, the positioning bolt 11 is screwed into the corresponding positioning hole 10 to lock the slide rod 4.

[0030] like Figures 2-3As shown, in order to reduce friction between the support groove 2 and the profile, a number of pulleys 12 are rotatably installed at the bottom of the support groove 2 along the conveying direction, and the pulleys 12 are arranged in a matrix. When the profile passes through the bottom of the support groove 2, it will drive the pulleys 12 to rotate, thereby reducing friction between the support groove 2 and the profile.

[0031] like Figure 1 As shown, baffles 15 are evenly spaced along the length of the bottom of the cooling tank 1. The baffles 15 are in the shape of a raised arc. The baffles 15 can reduce the flow rate of the cooling water in the cooling tank 1 and increase the heat exchange effect between the profile and the cooling water.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
