Interval flower color dovetail groove pipe head sucking pipe machining production line

Abstract

The invention discloses an internal flower color dovetail groove pipe head sucking pipe machining production line which comprises a rack (1), and a feeding device (2), a heating device (3), an extrusion molding die (4), a vacuum foam removing device (5), a cooling plastic device (6) and a cutting discharging device (7) which are sequentially arranged on the rack (1). The cooling plastic device (6)comprises a cooling box (8) fixedly connected with the rack. The two ends of the cooling box (8) are provided with a sealing feeding opening (9) and a sealing discharging opening (10) correspondingly, wherein the sealing feeding opening (9) and the sealing discharging opening (10) are the same in height. A partition plate (11) is arranged in the cooling box (8) and provided with a sealing transition opening (12). The height of the sealing transition opening (12) is the same as that of the sealing feeding opening (9). The production line is convenient to operate, and has the advantages of being low in cost, uniform in coloring, high in working efficiency and good in product quality.

Description

technical field [0001] The invention relates to straw production equipment, in particular to a production line for processing straws with dovetail grooves at intervals. Background technique [0002] At present, the production of common straws on the market is generally to heat and melt the plastic particles before extrusion molding, and to cool and shape the shaped straws, and finally to cut the strip-shaped straws into finished products; while the existing The cooling and shaping device of the company directly sends cold water into the cooling box of a certain length, so that the extruded straw is cooled and shaped by the cold water in the cooling box; due to the large temperature difference in different seasons, the extruded straw needs The cooling time is different. In the existing cooling and shaping device, the straw needs to go through a fixed cooling length every time. In winter, after the straw passes through a certain length in the cooling box, the straw has been co...

[0002] At present, the production of common straws on the market is generally to heat and melt the plastic particles before extrusion molding, and to cool and shape the shaped straws, and finally to cut the strip-shaped straws into finished products; while the existing The cooling and shaping device of the company directly sends cold water into the cooling box of a certain length, so that the extruded straw is cooled and shaped by the cold water in the cooling box; due to the large temperature difference in different seasons, the extruded straw needs The cooling time is different. In the existing cooling and shaping device, the straw needs to go through a fixed cooling length every time. In winter, after the straw passes through a certain length in the cooling box, the straw has been cooled and shaped, and it has reached the time for subsequent cutting. Appropriate temperature, neither too soft nor too hard; excess cooling water in the cooling water tank will continue to cool the straw, which will lead to poor final cooling effect of the straw, making the straw too hard to be suitable for subsequent cutting; therefore, When the temperature difference between winter and summer is relatively large, it is inconvenient to replace cooling boxes of different lengths; or put the equipment in a constant temperature environment, and the constant temperature environment requires air conditioning to adjust, which consumes a lot of energy
