Description

Technical Field

[0001] This utility model relates to the field of plastic pellet feeding technology, and in particular to a plastic pellet feeding machine. Background Technology

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. Under a specific temperature, completely molten plastic material, stirred by a screw, is injected into a mold cavity under high pressure. After cooling and solidification, the molded part is obtained. This method is suitable for the mass production of complex-shaped parts and is one of the important processing methods. During the injection molding process, plastic granules are generally conveyed and fed in using a feeding machine.

[0003] Traditional plastic granule feeders have some drawbacks. In actual operation, because plastic granules of different sizes are mixed together during feeding, this causes many problems in subsequent processing stages, such as injection molding and extrusion molding, due to the unevenness of the granules. This neglects the importance of pre-screening the plastic granules, directly resulting in the feeding effect not reaching the ideal state. Utility Model Content

[0004] The main objective of this invention is to provide a plastic granule feeding machine that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A plastic granule feeding machine includes a feeding hopper and a feed bin. A plastic granule feeding auxiliary mechanism is provided at the upper end of the feed bin. The plastic granule feeding auxiliary mechanism includes a support frame fixedly connected to the upper end of the feed bin. A sliding groove is provided at one end of the support frame. A filter plate is slidably connected to the inner side of the sliding groove. Filter holes are provided at the upper end of the filter plate. A connecting frame is fixedly connected to the front end of the filter plate. A control seat is fixedly connected to one end of the connecting frame. An electric wheel is drivenly connected to the inner side of the control seat. A limiting rail is fixedly connected to the inner wall of the support frame. A push plate is slidably connected to the outer side of the limiting rail. A pull rod is fixedly connected to one end of the push plate.

[0007] Preferably, the upper end of the support frame is fixedly connected to a material receiving port, the number of filter holes is several sets, and the rear end of the electric wheel is installed at the front end of the support frame.

[0008] Preferably, the connecting frame is L-shaped, and the lower end of the push plate is slidably connected to the upper end of the filter plate.

[0009] Preferably, the pull rod is located inside the filter plate, the number of connecting frames is four, and the number of control seats and electric wheels is two.

[0010] Preferably, the feeding hopper is installed at the upper end of the feeding hopper, and a screw frame is installed on the inner side of the feeding hopper. The screw frame penetrates the interior of the feeding hopper and is movably connected to the feeding hopper.

[0011] Preferably, a motor is installed at one end of the feeding hopper, one end of the screw frame is installed inside the motor, and a support frame is fixedly connected to the lower end of the feeding hopper.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By activating the electric wheel, the electric wheel rotates back and forth repeatedly, which in turn drives the control seat to move back and forth repeatedly. The control seat, through the connecting frame, pulls the filter plate to move back and forth repeatedly inside the sliding groove. This facilitates the screening of smaller and more uniform plastic particles through the filter holes, while leaving larger plastic particles on the filter plate, thus ensuring that the plastic particles used in subsequent processing are of uniform size.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-4As shown, a plastic granule feeding machine includes a feeding bin 1 and a feeding bin 2. A plastic granule feeding auxiliary mechanism 6 is provided at the upper end of the feeding bin 2. The plastic granule feeding auxiliary mechanism 6 includes a support frame 61 fixedly connected to the upper end of the feeding bin 2. A sliding groove 62 is opened at one end of the support frame 61. A filter plate 63 is slidably connected to the inner side of the sliding groove 62. A filter hole 64 is opened at the upper end of the filter plate 63. A connecting frame 65 is fixedly connected to the front end of the filter plate 63. A control seat 66 is fixedly connected to one end of the connecting frame 65. An electric wheel 67 is drivenly connected to the inner side of the control seat 66. A limiting rail 68 is fixedly connected to the inner wall of the support frame 61. A push plate 69 is slidably connected to the outer side of the limiting rail 68. A pull rod 610 is fixedly connected to one end of the push plate 69.

[0021] In this embodiment, the upper end of the support frame 61 is fixedly connected to the receiving port 611, the number of filter holes 64 is several sets, the rear end of the electric wheel 67 is installed at the front end of the support frame 61, the connecting frame 65 is L-shaped, the lower end of the push plate 69 is slidably connected to the upper end of the filter plate 63, the pull rod 610 is located in the inner side of the filter plate 63, the number of connecting frames 65 is four sets, and the number of control seats 66 and electric wheels 67 is two sets each.

[0022] Specifically, firstly, plastic granules are poured into the receiving port 611, placing them on the filter plate 63. Then, the electric wheel 67 is activated, causing it to rotate repeatedly. This rotation drives the control seat 66 to move repeatedly, and the control seat 66, via the connecting frame 65, pulls the filter plate 63 to move repeatedly within the sliding groove 62. This causes the plastic granules at the top of the filter plate 63 to fall through the filter holes 64, while plastic granules with a diameter larger than the filter holes 64 remain on the filter plate 63, thus reducing the diameter of plastic granules smaller than the filter holes. The relatively uniform plastic particles fall into the holes 64. By activating the electric wheel 67, the electric wheel 67 rotates back and forth repeatedly, which in turn drives the control seat 66 to move back and forth repeatedly. The control seat 66, through the connecting frame 65, pulls the filter plate 63 to move back and forth repeatedly inside the sliding groove 62. This facilitates the screening of smaller and more uniform plastic particles through the filter holes 64, while leaving plastic particles with a diameter larger than the filter holes 64 on the filter plate 63, thus ensuring that the plastic particles used in subsequent processing are of uniform size.

[0023] In this embodiment, the feeding bin 2 is installed at the upper end of the feeding bin 1. A screw frame 3 is installed on the inner side of the feeding bin 1. The screw frame 3 penetrates the interior of the feeding bin 1 and is movably connected to the feeding bin 1. A motor 4 is installed at one end of the feeding bin 1, and one end of the screw frame 3 is installed inside the motor 4. A support frame 5 is fixedly connected to the lower end of the feeding bin 1.

[0024] Specifically, the plastic granules fall into the feeding hopper 1, and at the same time, the motor 4 is started, which drives the screw frame 3 to rotate inside the feeding hopper 1, thereby moving the plastic granules in the feeding hopper 1 upward and conveying the plastic granules upward.

[0025] Working principle:

[0026] In use, first, pour plastic granules into the receiving port 611, so that the plastic granules are positioned on the filter plate 63. Then, start the electric wheel 67, causing it to rotate back and forth repeatedly. This causes the electric wheel 67 to drive the control seat 66 to move back and forth repeatedly, and the control seat 66, through the connecting frame 65, pulls the filter plate 63 to move back and forth repeatedly inside the sliding groove 62. This causes the plastic granules at the top of the filter plate 63 to fall down through the filter holes 64, while plastic granules with a diameter larger than the filter holes 64 remain on the filter plate 63. This allows the more uniform plastic granules with a diameter smaller than the filter holes 64 to fall down into the feeding hopper 1. At the same time, start the motor 4, causing the motor 4 to drive the screw frame 3 to rotate inside the feeding hopper 1, thus moving the plastic granules in the feeding hopper 1 upwards. The material is fed upwards, and the pull rod 610 is pulled, causing the pull rod 610 to drive the push plate 69 to slide along the limiting rail 68. This push plate 69 pushes away the plastic particles left on the filter plate 63 and pushes the remaining plastic particles out of the sliding groove 62, making it easier for workers to collect the remaining plastic particles. By starting the electric wheel 67, the electric wheel 67 rotates back and forth repeatedly, causing the electric wheel 67 to drive the control seat 66 to move back and forth repeatedly. The control seat 66, through the connecting frame 65, pulls the filter plate 63 to move back and forth repeatedly inside the sliding groove 62. This makes it easier to screen smaller and more uniform plastic particles through the filter holes 64, and leaves plastic particles with a diameter larger than the filter holes 64 on the filter plate 63, thus making the plastic particles used for subsequent processing uniform in size.
