Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0026] As shown in the drawings, Figures 1-3 The blow molding machine provided by the embodiment of the application can quickly replace the blow molding head 600, and the blow molding machine comprises a blow molding machine body 100, an extrusion pipe 200, a T-shaped wedge 400 and a blow molding head 600, wherein the blow molding machine body 100 comprises the extrusion pipe 200, the extrusion pipe 200 is used to extrude molten thermoplastic into a tubular parison through the blow molding machine body 100 in the blow molding process, then compressed air is injected into the parison through the blow molding machine to make the parison expand and tightly adhere to the inner wall of the mold, and finally the tubular product is formed after cooling and demolding.
[0027] The extrusion pipe 200 is provided with a plurality of locking frames 300 close to the outer wall of the port, the plurality of locking frames 300 are equidistantly distributed along the circumferential direction, and the side surface of each locking frame 300 is provided with a notch 310 in communication with the inside thereof, and the inside of each locking frame 300 is further provided with an arc-shaped slot 320 extending along the width direction of the locking frame 300. Preferably, the length of the upper edge of the locking frame 300 is less than the length of the lower edge thereof.
[0028] In the embodiment, the top surface of the upper edge of the locking frame 300 is vertically provided with the T-shaped wedge 400, and specifically, the T-shaped wedge 400 is slidingly arranged on the upper edge of the locking frame 300. The T-shaped wedge 400 comprises a horizontal section 410 and a vertical section 420 vertically connected to the horizontal section 410, and a spiral spring 500 is arranged between the horizontal section 410 of the T-shaped wedge 400 and the upper edge of the locking frame 300. Preferably, the surface of the upper edge of the locking frame 300 is provided with a spring seat 900 matched with the spiral spring 500. The end of the vertical section 420 of the T-shaped wedge 400 is symmetrically provided with an inclined surface 421 along the width direction, and in the initial state, the vertical section 420 and the inclined surface 421 of the T-shaped wedge 400 are located inside the arc-shaped slot 320 of the locking frame 300.
[0029] As shown in the drawings, Figures 2-3As shown, the blow head 600 is provided with a plurality of connecting columns 700 near the outer wall of the end portion, which are equidistantly distributed along the circumferential direction of the blow head 600. In actual use, the blow head 600 can drive the connecting columns 700 to rotate, and make the connecting columns 700 enter the arc-shaped slot 320 inside the locking frame 300 from the gap 310.
[0030] In the blow molding machine provided by the embodiments of the present application, when it is necessary to replace or install the blow head 600, the center of the blow head 600 is aligned with the center of the extrusion pipe 200 of the blow molding machine body 100, and then the blow head 600 is rotated so that the connecting columns 700 can enter the locking frame 300 on the outer wall of the extrusion pipe 200. Then, the blow head 600 is rotated again with more force, so that the connecting columns 700 can be in contact with the inclined surface 421 of the T-shaped wedge block 400, and force the T-shaped wedge block 400 to move upward. The connecting columns 700 of the blow head 600 will be in contact with the locking frame 300, and the T-shaped wedge block 400 will clamp the connecting columns 700 between it and the locking frame 300 under the elastic force of the spiral spring 500. With the above structure design, the process of replacing the blow head 600 of the blow molding machine can be simplified, so that the blow head 600 can be replaced in time and quickly to meet the actual production needs.
[0031] In some embodiments, the end portion of the blow head 600 extends outward along the axial direction to form a connecting pipe 800, and the outer diameter of the connecting pipe 800 is smaller than the outer diameter of the blow head 600. The blow head 600 can be connected to the extrusion pipe 200 through the connecting pipe 800, so that the center of the blow head 600 can be quickly aligned with the center of the extrusion pipe 200, and the subsequent rotation and installation process is facilitated.
[0032] In some embodiments, the wall surface of the connecting column 700 is provided with a groove 710, and the connecting column 700 is in contact with the frame of the locking frame 300 through the groove 710. In this way, the contact area of the connecting column 700 and the locking frame 300 can be increased, so as to reduce the probability of accidental disengagement of the connecting column 700 from between the T-shaped wedge block 400 and the locking frame 300.
[0033] In some embodiments, the outer wall of the blow head 600 is provided with the connecting column 700 through the connecting lug, the connecting column 700 is connected perpendicularly to the connecting lug, and the connecting column 700 extends along the axial direction of the blow head 600.
