Description

Technical Field

[0001] The utility model relates to the field of feeding devices for injection molding machines, and particularly relates to a feeding mechanism for a co-injection cap injection molding machine. Background Technique

[0002] A co-injection cap injection molding machine is a special injection molding machine used for producing bottle caps. It can inject different materials simultaneously or sequentially to produce bottle caps with multi-layer or composite structures. This technology is usually used for manufacturing bottle caps in industries such as beverages, food, and pharmaceuticals to achieve better sealing performance, corrosion resistance, or other special functions.

[0003] The applicant found through retrieval that the Chinese patent discloses "a feeding mechanism for an injection molding machine" with the publication number of "CN216544379U". This patent mainly enables the device to be used through the cooperation of a support plate, a chute, a slider, a feed bin, a cavity, a screw, and a locking nut. Since the slider is slidably connected inside the chute, when the staff moves the feed bin, the feed bin will move inside the chute through the slider, thus facilitating the staff to lower the feed bin and add materials to the inside of the feed bin. After adding materials, the staff displaces the feed bin upward and twists the locking nut so that the locking nut contacts the outer surface of the support plate to fix the slider. The staff keeps the discharge pipe perpendicular to the feed port of the injection molding machine, and then feeds the injection molding machine through the discharge pipe.

[0004] The above device can achieve the effects of facilitating feeding the injection molding machine and preventing the material from solidifying through a series of structures. However, when the above device is used, after the inside of the feed bin is filled with materials, the staff still needs to manually lift the feed bin to a certain height, which consumes a large amount of physical strength of the operator. And when stirring the materials in the feed bin, the stirring range is small, and the materials are generally relatively viscous, resulting in a poor stirring effect on the materials.

The output end of the stirring motor 301 penetrates through the top surface of the mounting frame 306 and is fixedly connected to a connecting rod 307. The bottom ends of the connecting rods 307 all penetrate through the top surface of the feeding box 10 and extend into the interior of the feeding box 10. A stirring rod 302 is slidably connected to the rod wall of the connecting rod 307. A plurality of stirring blades 303 are fixedly connected to the rod wall of the stirring rod 302. The stirring blades 303 can stir the materials inside the feeding box 10 to prevent the materials inside the feeding box 10 from solidifying. The stirring assembly 3 further includes two mounting grooves 310 which are respectively opened on both sides of the inner wall of the stirring rod 302. Springs 309 are fixedly connected to the bottom surfaces of the inner walls of the two mounting grooves 310. The top ends of the two springs 309 are both fixedly connected to a rectangular block 308. The rectangular block 308 enables the stirring rod 302 to rotate along with the rotation of the connecting rod 307. The opposite surfaces of the two rectangular blocks 308 are respectively fixedly connected to both sides of the rod wall of the connecting rod 307. The opposite surfaces of the two rectangular blocks 308 are respectively slidably connected to the inner walls of the corresponding mounting grooves 310. The stirring assembly 3 further includes two triangular blocks 305 and a linkage plate 304. The bottom surfaces of the two triangular blocks 305 are both fixedly connected to the bottom surface of the inner wall of the feeding box 10. The top surface of the linkage plate 304 is fixedly connected to the bottom end of the stirring rod 302. The linkage plate 304 is trapezoidal in shape, and the two inclined surfaces of the linkage plate 304 can cooperate with the inclined surfaces of the two triangular blocks 305.

[0025] As Figure 4 shown in the figure, the control assembly 4 includes a control motor 401. One side of the control motor 401 is fixedly connected to the top surface of the cross plate 13. The output end of the control motor 401 penetrates through the top surface of the cross plate 13 and is fixedly connected to a lead screw 402. The bottom end of the lead screw 402 is rotatably connected to the top surface of the base 1. A connecting block 403 is threadedly connected to the rod wall of the lead screw 402. The connecting block 403 can rotate along with the rotation of the lead screw 402. One side of the connecting block 403 is fixedly connected to one side of the feeding box 10.

[0026] As Figure 1 and Figure 2 shown in the figure, universal wheels 6 are fixedly connected to the four corners of the bottom surface of the base 1. A control panel 11 is fixedly connected to one side of one of the vertical plates 5. The control panel 11 can control the start and stop of the stirring motor 301 and the control motor 401. A feeding pipe 12 is fixedly connected to the top surface of the feeding box 10. A discharge pipe 8 is fixedly connected to the bottom surface of the feeding box 10. The discharge pipe 8 can discharge the materials inside the feeding box 10. Both the discharge pipe 8 and the feeding pipe 12 are communicated with the inner wall of the feeding box 10. An electromagnetic valve 9 is fixedly connected to the pipe wall of the discharge pipe 8. The electromagnetic valve 9 can control the opening and closing of the discharge pipe 8.

[0027] Working principle of the utility model: When the device is in use, first put the material into the interior of the feeding box 10 through the feeding pipe 12, and then start the control motor 401 to drive the lead screw 402 to rotate. When the lead screw 402 rotates, the feeding box 10 can move upward along the rod wall of the lead screw 402 with the connecting block 403 through the settings of the two limit slots 201 and the two limit blocks 202 until the feeding box 10 moves to the highest position. Then, move the whole device to the front of the injection molding machine that needs feeding through the universal wheels 6, and make the discharge pipe 8 face the feeding port of the injection molding machine. Then start the stirring motor 301, and the stirring motor 301 can drive the connecting rod 307 and the stirring rod 302 to rotate. During the rotation of the stirring rod 302, the material inside the feeding box 10 can be stirred through the stirring blades 303, so as to prevent the material inside the feeding box 10 from solidifying. And during the rotation of the stirring rod 302, the linkage plate 304 can be driven to rotate. When the linkage plate 304 rotates, it can cooperate with the two triangular blocks 305. When the two hypotenuses of the linkage plate 304 contact the two triangular blocks 305, the stirring rod 302 can move upward along the rod wall of the connecting rod 307, and when moving, the two rectangular blocks 308 can compress the two springs 309. Then when the linkage plate 304 disengages from the two triangular blocks 305, the two springs 309 stretch, driving the stirring rod 302 to move downward. Thus, the stirring rod 302 can move up and down reciprocally while stirring, increasing the stirring range. Then open the solenoid valve 9 to discharge the material inside the feeding box 10 through the discharge pipe 8 into the feeding port of the injection molding machine. The original text highlights the innovative structure and does not elaborate too much on the prior art.
