DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] See also Figure 1-4 The utility model provides an embodiment: a headphone diaphragm thermoplastic molding machine, comprising: a base 1, a thermoplastic component 2 for thermoplastic molding operation is installed in the middle above the base 1, the thermoplastic component 2 includes a hot pressing mold 9 located in the middle of the upper surface of the base 1, a hot pressing plate 8 is installed above the hot pressing mold 9, and a first driving member 7 for driving the hot pressing plate 8 to move up and down is installed above the hot pressing plate 8. A positioning component 3 is installed at one end away from the thermoplastic component 2 with an unwinding end 4 for unwinding the thermoplastic part.

[0022] The first driving member 7 is used to drive the hot pressing plate 8 to move up and down. When moving down, the hot pressing plate 8 contacts the thermoplastic part and presses the thermoplastic part down to the hot pressing mold 9. After waiting for a period of time, the hot pressing plate 8 is lifted up to form the thermoplastic part by hot pressing.

[0023] See also Figure 1 , Figure 3 The other positioning component 3 is provided with a cutting component 5 for cutting the thermoplastic component at one end away from the thermoplastic component 2. The cutting component 5 includes a cutting tool 13 located therein, and a third driving component 12 for driving the cutting tool 13 to move is installed at the upper end thereof.

[0024] By setting the positioning component 3, the cutting tool 13 can be driven to move up and down through the third driving member 12 to adjust the height of the cutting tool 13. During the downward movement, the cutting tool 13 is driven to contact the thermoplastic part formed by hot pressing below, and the thermoplastic part is cut by pressing down to achieve the effect of cutting and separation, so that the cutting and blanking operation can be carried out quickly after thermoplasticization.

[0025] See also Figure 1 , Figure 4 A clamping and pulling assembly 6 is installed at one end of the cutting assembly 5 away from the positioning assembly 3, which is used to clamp the thermoplastic part and move it outward to pull it out. The clamping and pulling assembly 6 includes a plurality of clamping members 17 for clamping operations. The clamping member 17 includes clamping claws 19 located at the upper and lower ends thereof. An electric telescopic rod 18 is installed between the clamping claws 19 and the clamping member 17 for driving the clamping claws 19 to perform clamping operations.

[0026] The electric telescopic rod 18 is used to drive the two clamping jaws 19 to move, and the distance between the two clamping jaws 19 is adjusted by displacement, so as to control the clamping and releasing states.

[0027] See also Figure 4 The clamping member 17 also includes an adjusting component 20 for adjusting the clamping height, and the adjusting component 20 is located at the rear end of the clamping member 17 .

[0028] The adjustment component 20 can be a screw module, which drives the clamping member 17 to move up and down to adjust the clamping height; of course, the adjustment component 20 can also be a pneumatic component, an electric push rod, a hydraulic component or other device that can drive the clamping member 17 to move up and down.

[0029] See also Figure 1 The clamping and pulling assembly 6 also includes a moving assembly 14 for driving the clamping member 17 to move forward and backward, and the moving assembly 14 is symmetrically arranged at the lower bottom of the clamping and pulling assembly 6. The moving assembly 14 includes a ball screw 15, and a screw slider 16 is installed on the outer wall of the ball screw 15.

[0030] The screw motor (not shown in the figure) and the ball screw 15 drive the screw slider 16 to move linearly, and drive the clamping member 17 to move forward and backward. Through the forward and backward displacement, before clamping, it moves to the cutting component 5 to clamp the end of the thermoplastic part. After clamping, it moves backward to pull the thermoplastic part outward and displace the thermoplastic part to move the thermoplastic part to the cutting position for cutting. At the same time, it drives the unwinding end 4 to unwind and pull the new thermoplastic part under the thermoplastic component 2 to facilitate the thermoplastic molding effect.

[0031] See also Figure 1 , Figure 3 Both ends of the thermoplastic component 2 are equipped with positioning components 3 for fixing the thermoplastic parts. The positioning component 3 includes a positioning pressure plate 11 located inside it, and the upper end of the positioning pressure plate 11 is equipped with a second driving component 10 for driving the positioning pressure plate 11 to move up and down.

[0032] The second driving member 10 is used to drive the positioning platen 11 to move up and down. When moving downward, the positioning platen 11 presses down the thermoplastic part to prevent it from shifting during the thermoplastic process, and can limit the end of the thermoplastic part to avoid the thermoplastic part from detaching after the clamping part is loosened, affecting the entire thermoplastic cutting displacement operation.

[0033] Furthermore, the first driving member 7, the second driving member 10, and the third driving member 12 can be driven by any one of electric, pneumatic, or hydraulic methods.

[0034] The electric method includes electric parts with lifting functions such as electric cylinders and electric push rods, and also includes driving parts such as air cylinders and hydraulic cylinders that can realize lifting and moving functions.

[0035] Working principle: When in use, place the thermoplastic unwinding drum at the unwinding end 4, stretch the end of the thermoplastic to the farthest positioning component 3, the positioning component 3 presses it down to position, the first driving member 7 drives the hot pressing plate 8 to move downward, press the thermoplastic to the hot pressing mold 9, and perform hot pressing operation;

[0036] After hot pressing, the hot pressing plate 8 moves upward, the moving assembly 14 drives the clamping member 17 to move forward to the positioning assembly 3, the adjusting assembly 20 adjusts the clamping height, the electric telescopic rod 18 drives the clamping claw 19 to clamp the thermoplastic part, and after clamping, the positioning assembly 3 releases the thermoplastic part upward, the moving assembly 14 moves backward, drives the thermoplastic part to move backward, pulls the thermoplastic part out to the cutting position, and stretches and moves the new thermoplastic part to the bottom of the thermoplastic assembly 2;

[0037] The positioning component 3 is pressed down again for positioning, and the third driving member 12 drives the cutting tool 13 to cut the thermoplastic part located there. The moving component 14 can drive the cut thermoplastic part to move to the material collection position, release the clamping jaws 19 to separate the thermoplastic part, and then reset and move it to the cutting position to perform a new round of thermoplastic cutting and material collection operation.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
