Description

Technical Field

[0001] The utility model relates to the field of hot-melt devices, in particular to a hot-melt device for plastic processing. Background Art

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0021] like Figure 1-2 As shown, the utility model provides a hot melt device for plastic processing, comprising a hot melt tube 1, wherein a crushing and leaking mechanism 2 is provided inside the hot melt tube 1 for rotation;

[0022] A mounting frame 3 is fixedly mounted on the hot melt cylinder 1, and a driving mechanism 4 for driving the crushing and leaking mechanism 2 to rotate is provided on the mounting frame 3;

[0023] A heating element 5 is provided on the driving mechanism 4 .

[0024] In an optional embodiment, the crushing and leakage mechanism 2 includes a leakage pipe 21 and a crushing knife 22. The leakage pipe 21 is rotatably sleeved on the hot melt tube 1, and the crushing knife 22 is fixedly installed on the leakage pipe 21. A leakage opening is opened on the leakage pipe 21.

[0025] Furthermore, a stirring rod 23 is fixedly mounted on the leakage pipe 21 .

[0026] A valve is provided at the discharge end of the leakage pipe 21 .

[0027] It should be noted that when the stirring rod 23 rotates, the unmelted plastic and the plastic liquid can be mixed and changed in position, thereby increasing the subsequent melting rate.

[0028] In an optional embodiment, the driving mechanism 4 includes a driving member 41, a connecting frame 42, a screw rod 43 and a transmission block 44. The driving member 41 is fixedly mounted on the mounting frame 3. The driving rod of the driving member 41 is fixedly connected to the screw rod 43 through the connecting frame 42. The transmission block 44 is fixedly mounted inside the leakage pipe 21. A rectangular opening is opened on the transmission block 44 for the screw rod 43 to pass through.

[0029] Specifically, the driving member 41 is a cylinder or a hydraulic cylinder.

[0030] A heating plate 6 is embedded in the inner wall of the hot melt tube 1 .

[0031] The spiral rod 43 is fixedly connected to the connecting frame 42 through a round rod, and the diameter of the round rod is the same as the width of the rectangular opening of the transmission block 44, so that the round rod does not interfere with the rotation of the transmission belt block 44 when it extends into the rectangular opening.

[0032] In the utility model, plastic particles are added to the interior of the hot melt tube 1, and the driving member 41 drives the heating member 5 to extend into the interior of the hot melt tube 1 to heat the plastic particles. As the spiral rod 43 is continuously extended, the spiral rod 43 passes through the rectangular opening of the transmission block 44. As the spiral rod 43 is continuously passed through, the leakage pipe 21 and the crushing knife 22 are driven to rotate, and the vertical position of the heating member 5 is changed. At the same time, the crushing knife 22 crushes and stirs the plastic, thereby increasing the melting rate, increasing the melting efficiency, and improving the phenomenon of timely availability.

[0033] Furthermore, a heating plate 6 is embedded in the inner wall of the hot melt tube 1. The heating plate 6 melts when it melts again after solidification. At this time, the driving member 41 can be started to drive the heating member 5 to extend to the top of the solidified plastic for melting. As the plastic and the hot melt tube 1 gradually melt, the melted plastic liquid on the top continuously flows downward from the inner periphery of the hot melt tube 1 and continuously softens. The driving member 41 drives the accompanying screw rod 43 to continuously extend in, and the screw rod 43 passes through the rectangular opening of the transmission block 44. As the accompanying screw rod 43 continuously passes through, it drives the leakage pipe 21 and the crushing knife 22 to rotate, and while changing the vertical position of the heating member 5, the crushing knife 22 crushes and stirs the plastic, thereby increasing the melting rate, increasing the melting efficiency, and improving the phenomenon of timely availability.
