For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0018] See also Figures 1 to 4 , an anti-clogging injection molding machine, comprising a feeding device 10 for material conveying; the feeding device 10 comprises an outer cylinder 101 connected to a feeding port, an inner cylinder 102 installed in the outer cylinder 101, a first connecting plate 103 installed on the inner side of the upper end of the inner cylinder 102, a first pushing block 104 installed on the inner side of the outer cylinder 101, a second pushing block 105 installed on the outer side of the inner cylinder 102 and pushing against the first pushing block 104, and a driving component connected to the first connecting plate 103 for driving the first connecting plate 103 to rotate; wherein a slide groove is provided on a side of the first connecting plate 103 close to the inner cylinder 102; a slider 106 is slidably installed in the slide groove; the slider 106 is connected to the inner cylinder 102; a return spring 107 connected to the slider 106 is also provided in the slide groove.
[0019] Specifically, in this embodiment, the material enters the injection molding machine from the feed port through the inner cylinder 102. During the material conveying process, the driving assembly drives the first connecting plate 103 to rotate, and then drives the inner cylinder 102 to rotate relative to the outer cylinder 101 through the slider 106. At the same time, due to the setting of the first push block and the second push block 105, when the inner cylinder 102 rotates relative to the outer cylinder 101, the inner cylinder 102 is vertically displaced relative to the outer cylinder 101, and then drives the slider 106 to move in the slide groove. After the first push block 104 and the second push block 105 release the push, the reset spring 107 works to drive the inner cylinder 102 to reset. Since the inner cylinder 102 rotates relative to the outer cylinder 101 during feeding, and the slider 106 and the reset spring 107 are set, the inner cylinder 102 oscillates vertically when it rotates vertically, so that the material can be effectively prevented from accumulating on the inner wall of the inner cylinder 102, thereby improving the feeding effect and effectively preventing blockage.
[0020] The utility model relates to an anti-clogging injection molding machine. Through the setting of the feeding device 10, when feeding, the inner cylinder 102 rotates relative to the outer cylinder 101, and through the setting of the slider 106 and the return spring 107, the inner cylinder 102 oscillates vertically when rotating vertically, so that the material can be effectively prevented from accumulating on the inner wall of the inner cylinder 102, thereby improving the feeding effect and effectively preventing clogging.
[0021] In a specific embodiment, the driving assembly includes a second connecting plate 108, a third connecting plate 109, a transmission gear 110 and a driving motor 111; the second connecting plate 108 is mounted on the first connecting plate 103 and is slidably connected to the upper end of the outer cylinder 101; the third connecting plate 109 is mounted on the outer side of the outer cylinder 101 and is connected to the second connecting plate 108, and a gear bar 112 is provided on the outer side of the third connecting plate 109; the transmission gear 110 is mounted on the outer side of the third connecting plate 109 and is meshed with the gear bar 112; the driving motor 111 is connected to the transmission gear 110 to drive the transmission gear 110 to rotate. In this embodiment, when working, the driving motor 111 drives the transmission gear 110 to rotate, and then drives the second connecting plate 108 to slide relative to the upper end of the outer cylinder 101 through the gear bar 112, and drives the first connecting plate 103 to rotate relative to the inner cylinder 102.
[0022] In a specific embodiment, feed rods 113 are equidistantly arranged on the inner wall of the inner cylinder 102; the feed rods 113 are arranged obliquely downward from the inner wall of the inner cylinder 102. In this embodiment, the feed rods 113 are arranged to effectively improve the feed efficiency, which is suitable for industrial applications.
[0023] In a specific embodiment, an injection molding device 20 is further included; a feed port of the injection molding device 20 is connected to the outer barrel 101 .
[0024] The utility model relates to an anti-clogging injection molding machine. Through the setting of the feeding device 10, when feeding, the inner cylinder 102 rotates relative to the outer cylinder 101, and through the setting of the slider 106 and the return spring 107, the inner cylinder 102 oscillates vertically when rotating vertically, so that the material can be effectively prevented from accumulating on the inner wall of the inner cylinder 102, thereby improving the feeding effect and effectively preventing clogging.
