Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0028] like Figure 1-Figure 9 As shown, this embodiment provides an embodiment of a metering and discharging mechanism of an EVA injection molding machine.
[0029] A metering and discharging mechanism of an EVA injection molding machine comprises a frame 1 and a material storage barrel 2, wherein an injection machine 3 is mounted on the frame 1, a metering structure 4 is arranged on the material storage barrel 2, the metering structure 4 comprises a motor 5 fixedly mounted on the bottom of the frame 1, a first gear 6 is fixedly mounted on the output end of the motor 5, a second gear 7 is meshedly connected to the first gear 6, a rotating rod 8 is fixedly mounted on one end of the second gear 7, a plurality of partitions 9 are fixedly mounted on the rotating rod 8, an isolating barrel 10 connected to the partitions 9 is fixedly mounted on the frame 1, a plurality of bottom plates 11 are fixedly mounted on the bottom of the isolating barrel 10, a weighing device 12 is fixedly mounted on the bottom of the bottom plate 11, the weighing device 12 is connected to the material storage barrel 2 through an electrical signal, a discharging port 13 is opened on one of the bottom plates 11, and a discharging port 13 is provided on the bottom of the metering structure 4. The setting has changed the traditional metering method, solved the problem of low metering accuracy, and will not cause waste of materials. It has realized that the raw materials can be pre-placed into multiple metering barrels and weighed and measured at the same time. The raw materials are transported to the isolation barrel 10 through multiple feeding pipes at the bottom of the storage barrel 2. When the input amount reaches the demand, the weighing device 12 sends a notification signal to the storage barrel 2 to close the feeding port of the storage barrel 2, and then starts the motor 5 to drive the first gear 6 and the second gear 7 to rotate. While the second gear 7 rotates, the rotating rod 8 also drives multiple partitions 9 to start rotating. When the raw material of each grid moves to the position of the discharge port 13, it can fall out and enter the next process. The storage barrel 2 will add raw materials to the partition where the raw material fell out again, and the cycle will save the time of raw material filling and improve work efficiency.
[0030] like Figure 1 As shown, a fixing plate 14 is fixedly mounted on the frame 1, a cylinder 15 is fixedly mounted on one end of the fixing plate 14, a feed box 16 connected to the frame 1 is mounted on the output end of the cylinder 15, and after the raw material enters the feed box 16, the cylinder 15 is started to pressurize the inside of the feed box 16, and then the raw material enters the injection molding machine 3 through the hose connected to the injection molding machine 3 under the action of pressure, and the injection molding machine 3 is started to inject into the molding mold, thereby increasing the utilization rate of the raw material and avoiding the raw material from being retained inside the feed box 16.
[0031] like Figure 6 As shown, a closed door 17 is provided on the feed box 16, and a plurality of slide grooves 18 are opened on the feed box 16. A slider 19 connected to the closed door 17 is movably installed inside the slide groove 18. By setting the closed door 17, the slide groove 18 and the slider 19, the feed box 16 can be opened or closed for the entry of raw materials. The slide groove 18 and the slider 19 can reduce the friction between the closed door 17 and the feed box 16, making it easier to open the closed door 17.
[0032] like Figure 6 As shown, a plurality of fixing rods 20 are fixedly installed on one side of the feed box 16, and a buckle 21 is movably installed on the fixing rod 20. A clamping block 22 used in conjunction with the buckle 21 is fixedly installed on the closing door 17. By setting the fixing rod 20, the buckle 21 and the clamping block 22, the buckle 21 is flipped over to engage with the clamping block 22, which can further tighten the closing door 17 and avoid air leakage when the cylinder 15 pressurizes the interior of the feed box 16, thereby affecting the entry of raw materials into the injection machine 3.
[0033] like Figure 2 As shown, a protective cover 23 connected to the frame 1 is installed on the outer side of the motor 5, and a plurality of heat dissipation holes 24 are opened on the protective cover 23. Through the setting of the protective cover 23 and the heat dissipation holes 24, the motor 5 can be protected from damage. The protective cover 23 can dissipate the heat generated by the motor 5 to prevent the motor 5 from overheating and reducing its service life.
[0034] like Figure 7As shown, the bottom of the protective cover 23 and the frame 1 are both provided with a plurality of cross holes 25, the inside of the cross hole 25 is movably provided with an insertion rod 26, the bottom of the insertion rod 26 is fixedly provided with a fixing block 27, and the inner side of the cross hole 25 is provided with a groove for use with the fixing block 27. Through the arrangement of the cross hole 25, the insertion rod 26, the fixing block 27 and the groove, the insertion rod 26 is inserted into the bottom of the cross hole 25, and then the insertion rod 26 is rotated to make it engage with the groove inside the cross hole 25, so that the protective cover 23 is fixed to the bottom of the frame 1, and the insertion rod 26 is rotated to turn the fixing block 27 out of the groove to make it consistent with the angle of the cross hole 25, so that the protective cover 23 can be disassembled and replaced in reverse when it is damaged.
[0035] like Fig. 9 As shown, a through slot is provided on the top of the frame 1, and an electric guide rail 28 is fixedly installed inside the through slot, and a transmission block 29 connected to the injection machine 3 is installed on the electric guide rail 28. After the raw material enters the injection machine 3, the electric guide rail 28 is started so that the transmission block 29 drives the injection machine 3 to move in the mold direction, and there is no need to manually operate the injection machine, which saves labor and reduces danger.
[0036] In this embodiment, if Figure 1-Figure 9 As shown, the working process of the metering and discharging mechanism of an EVA injection molding machine provided in this embodiment is as follows:
[0037] The raw materials are transported to the isolation cylinder 10 through multiple feed pipes at the bottom of the storage barrel 2. When the input amount reaches the requirement, the weighing device 12 sends a notification signal to the storage barrel 2 to close the feed port of the storage barrel 2, and then starts the motor 5 to drive the first gear 6 and the second gear 7 to rotate. While the second gear 7 rotates, the rotating rod 8 also drives multiple partitions 9 to start rotating. When each grid of raw materials moves to the position of the discharge port 13, it can fall out and enter the next process. The storage barrel 2 will add raw materials to the partition where the raw materials fell out again, and the cycle will save the time of raw material filling and improve work efficiency.
[0038] In summary, in this embodiment, according to the metering and discharging mechanism of an EVA injection molding machine of this embodiment, through the setting of the fixed plate 14, the cylinder 15 and the feed box 16, after the raw material enters the feed box 16, the cylinder 15 is started to pressurize the inside of the feed box 16, and then the raw material enters the inside of the injection machine 3 through the hose connected to the injection machine 3 under the action of pressure, and the injection machine 3 is started to be injected into the molding mold, thereby increasing the utilization rate of the raw material and avoiding the retention of the raw material in the feed box 16. By setting the closed door 17, the slide 18 and the slider 19, the feed box 16 can be opened or closed for the entry of the raw material. The slide 18 and the slider 19 can reduce the friction between the closed door 17 and the feed box 16, making it easier to open the closed door 17. By setting the fixed rod 20, the buckle 21 and the block 22, the buckle 21 is flipped over. The rotation and engagement with the card block 22 can further tighten the closed door 17 and prevent the cylinder 15 from leaking when pressurizing the inside of the feed box 16, thereby affecting the entry of raw materials into the injection machine 3. The protection cover 23 and the heat dissipation hole 24 can protect the motor 5 from damage. The protection cover 23 can dissipate the heat generated by the motor 5 to prevent the motor 5 from overheating and reducing its service life. Through the arrangement of the cross hole 25, the insertion rod 26, the fixing block 27 and the groove, the insertion rod 26 is inserted into the bottom of the cross hole 25, and then the insertion rod 26 is rotated to make it engage with the groove on the inner side of the cross hole 25, so that the protection cover 23 is fixed to the bottom of the frame 1, and the insertion rod 26 is rotated to rotate the fixing block 27 out of the groove to make it consistent with the angle of the cross hole 25. When the protection cover 23 is damaged, it can be disassembled and replaced in reverse, through the arrangement of the electric guide rail 28 and the transmission block 29. After the raw material enters the interior of the injection molding machine 3, the electric guide rail 28 is started so that the transmission block 29 drives the injection molding machine 3 to move in the mold direction. There is no need to manually operate the injection molding machine, which saves labor and reduces danger.
