[0002] In the production process of plastic particles, the plastic strips need to be extruded through an extruder first, and then sent to a pelletizer for pelletizing after being water-cooled in a cooling water tank to obtain plastic particles. Since the plastic strips are fully in contact with the cooling water during water cooling, the surface water content is relatively high, and they cannot dry naturally during the process of being sent to the pelletizer. Therefore, active water removal is required.

[0003] The utility model patent application number 201120349662.1 discloses a plastic strip water removal system. The plastic strip is dehydrated in the first step when passing through the brush, and then dehydrated in the second step through the blowing port and suction port of the blower. Although the plastic strip can be dehydrated, the brush cannot be dried. During use, the brush is saturated with water and cannot effectively perform the first step of water removal. In addition, the suction port will produce adsorption force on the plastic strip, hindering the normal transportation of the plastic strip, and needs to be improved. Utility Model Content

[0019] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1~Figure 2 , the utility model embodiment includes:

[0021] like Figure 1 The online dewatering device for plastic strips shown comprises: a cooling water trough 1, a brush plate 11, a first air knife 15, a guide roller 3, a first bracket 2 and a support plate 16. The first bracket 2 is arranged on the cooling water trough 1. The guide roller 3 is horizontally arranged in the first bracket 2 and extends along the width direction of the cooling water trough 1. The plastic strips are sent out through the guide roller 3 after being water-cooled in the cooling water trough 1. In this embodiment, a third air knife 4 is arranged at the bottom of the mounting plate 6 and is located behind the guide roller 3. The third air knife 4 is externally connected to a compressed air pipeline, and high-speed air is blown downward through the third air knife 4 to perform the first dewatering of the plastic strips.

[0022] In this embodiment, annular grooves are arranged at intervals on the guide roller 3, which can guide multiple plastic strips respectively, and use the annular grooves to increase the contact area with the plastic strips to perform a second water removal, and the water in the annular grooves is thrown out by the passive rotation of the guide roller 3 to avoid water accumulation.

[0023] like Figure 1 As shown, a second wind knife 5 is provided at the bottom of the mounting plate 6 in front of the guide roller 3. The second wind knife 5 performs a third wind cutting to remove water from the plastic strips passing thereunder, thereby greatly reducing the residual water on the surface of the plastic strips. Moreover, the water flows downward into the cooling water tank 1 with the air flow and can be reused to avoid waste.

[0024] A forward extending mounting plate 6 is provided on the top of the first bracket 2, and a brush plate 11 is arranged below the mounting plate 6 so as to be reciprocatingly movable along the width direction of the cooling water trough 1. In the present embodiment, a slider 13 is provided on the top of the brush plate 11, and a slide rail 12 corresponding to the slider 13 is provided on the bottom of the mounting plate 6 to guide the movement of the brush plate 11 and improve the stability of the reciprocating movement.

[0025] A connecting block 9 is provided on the brush plate 11, and the connecting block 9 can be fixed to the rear side of the brush plate 11 by screws, so that the structure is stable. Figure 2As shown, a waist hole 18 is vertically arranged in the connecting block 9, a motor 7 is arranged at the bottom of the mounting plate 6, a turntable 8 is arranged on the rotating shaft of the motor 7, and a driving shaft 10 extending into the waist hole 18 is eccentrically arranged on the turntable 8. The eccentric rotation of the driving shaft 10 is driven by the motor 7, and the synchronous reciprocating movement of the connecting block 9 and the brush plate 11 is realized by the cooperation between the driving shaft 10 and the waist hole 18.

[0026] In this embodiment, the motor 7 is located behind the brush plate 11, with a compact structure and high space utilization. The drive shaft 10 is provided with a bearing located in the waist hole 18, and the bearing is in rolling contact with the side wall of the waist hole 18 to reduce wear.

[0027] The support plate 16 is suspended below the brush plate 11. In this embodiment, the support plate 16 is densely covered with drainage holes, and the water on the support plate 16 can flow downward into the cooling water tank 1 through the drainage holes to avoid water accumulation. The support plate 16 is located in front of the guide roller 3 to support the plastic strips sent out through the guide roller 3. The cooling water tank 1 is provided with a second bracket 17 located at the bottom of the support plate 16. The second bracket 17 can fix the support plate 16 by screws to ensure the structural stability of the support plate 16.

[0028] like Figure 1 As shown, the bottom of the brush plate 11 is provided with bristles 14 extending downward to the top surface of the support plate 16. The brush plate 11 can drive the bristles 14 to move back and forth, and the movement of the bristles 14 is used to wipe the moisture on the surface of the plastic strip, thereby performing the fourth water removal and improving the water removal effect. In this embodiment, the bristles 14 are made of vinylon yarn, which has good hygroscopicity and is relatively wear-resistant.

[0029] The first wind knife 15 is arranged at the bottom of the mounting plate 6 and in front of the brush plate 11. In this embodiment, the air outlet of the first wind knife 15 is obliquely downwardly directed to the gap between the brush plate 11 and the support plate 16, so that the bristles 14 can be dried under the wind force of the first wind knife 15, ensuring the reliability of water removal. In addition, the plastic strip is dehydrated for the fifth time when passing under the first wind knife 15, ensuring the effect of water removal.

[0030] In summary, the online water removal device for plastic strips disclosed in the utility model has a high degree of automation and can remove water from the plastic strips multiple times online, thereby improving the drying effect of the surface of the plastic strips.

[0031] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
