Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, specifically to a precision injection molding machine that automatically recycles plastic granules. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection molding machines, are the main molding equipment used to make various shapes of plastic products from thermoplastic or thermosetting materials using plastic molds. By using the thrust of a screw (or plunger), the plasticized molten state (i.e., viscous flow state) of the plastic is injected into the closed injection mold cavity at high pressure and high speed. After cooling and solidification, a plastic product with a shape almost identical to the mold cavity is obtained. Currently, there are injection-molded plastic granules.

[0003] Chinese patent CN217777592U discloses a plastic injection molding machine for automatically removing and recycling plastic particles. This prior art is equipped with a motor, a drive shaft movably connected to one side of the motor, a turbine fan fixedly connected to one end of the drive shaft, and a wind shield fixedly connected to one side of the motor. This facilitates the collection of plastic particles generated during the injection molding process, which can then be recycled or destroyed in a unified manner, keeping the equipment clean and tidy during production.

[0004] The aforementioned equipment operates by using a worm gear to drive airflow, which in turn uses centrifugal force to move plastic granules into a collection box. Inside, a perforated partition plate blocks the material. However, the granules are not uniform in size, and granules with a similar aperture to the partition plate can easily get stuck in the holes, causing blockages and affecting the efficiency of airflow. Consequently, this impacts the efficiency of subsequent plastic granule recycling, requiring optimization and improvement. Utility Model Content

[0005] The purpose of this invention is to provide a precision injection molding machine for automatically recycling plastic granules, in order to solve the problem mentioned in the background art that if the separator plate is not cleaned in time when recycling plastic granules, the recycling efficiency will be affected.

[0007] The recycling adjustment component includes a recycling bin located at the inner top of the injection molding machine frame. A guide duct is connected to the inner front end of the recycling bin, a plug-in mounting block is connected to the top of the guide duct, and a positioning block is connected to the outer side of the guide duct. This recycling adjustment component is used for cleaning and adjusting plastic granules during recycling. The cleaning and collection component includes a pull-out block located at the rear end of the recycling bin. A collection hopper is located at the front end of the pull-out block, and a fine groove plate is located on the inner side of the collection hopper. This cleaning and collection component is used for cleaning and recycling plastic granules.

[0008] Preferably, the bottom of the recycling bin is provided with an adjustment groove, and a sliding block is connected to the inner side of the adjustment groove, and a compression elastic element is connected to the inner side of the sliding block.

[0009] Preferably, the outer wall of the guide duct is provided with a collection groove, and the rear end of the guide duct is connected to a discharge guide plate.

[0010] Preferably, a filter baffle is inserted into the inner side of the guide duct, and the insertion mounting block is installed on the top of the filter baffle.

[0011] Preferably, a fan is installed at the inner front end of the guide duct, and a clamp is connected to the outer side of the fan.

[0012] Preferably, an inclined support block is fixedly connected to the inner bottom end of the collecting hopper.

[0013] Preferably, an adhesive plate is bonded to the top of the inclined support block, and the fine groove plate is bonded to the top of the adhesive plate.

[0014] Preferably, the card plate has a threaded hole inside, and the positioning block has a screw connected inside.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model features a replaceable recycling bin for easy cleaning, and a filter baffle to block materials during collection, causing them to aggregate. Both the filter baffle and the fan are easy to disassemble and clean, thus avoiding any impact on the subsequent recycling efficiency of the recycling bin.

[0017] When collecting plastic granules in the collection hopper inside the recycling bin, the material is gathered by the guide of the inclined support block.

[0024] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0025] like Figure 1 - Figure 4 As shown, this application provides a precision injection molding machine for automatically recycling plastic granules, including: an injection molding frame 1, a molding chamber 2 installed on one side of the top of the injection molding frame 1, and a feeding box 3 installed on the side of the top of the injection molding frame 1 away from the molding chamber 2.

[0026] The recycling adjustment component includes a recycling box 4, which is located at the top inner side of the injection molding machine frame 1. A guide air duct 8 is connected to the front inner side of the recycling box 4. A plug-in mounting block 12 is connected to the top of the guide air duct 8, and a positioning block 15 is connected to the outer side of the guide air duct 8. The recycling adjustment component is used for cleaning and adjustment during the recycling of plastic particles.

[0027] Specifically, such as Figure 2As shown, the bottom of the recycling bin 4 is provided with an adjustment groove 5, and a sliding block 6 is connected to the inner side of the adjustment groove 5. A compression elastic element 7 is connected to the inner side of the sliding block 6. The sliding block 6 slides inside the adjustment groove 5. By the elastic force of the compression elastic element 7, the sliding block 6 is locked on both sides to position the recycling bin 4. The compression of the sliding blocks 6 on both sides makes it easy to remove the recycling bin 4.

[0028] Specifically, such as Figure 3 As shown, a collection groove 9 is provided on the outer wall of the guide duct 8, and a discharge guide plate 10 is connected to the rear end of the guide duct 8. The collection groove 9 at the top of the guide duct 8 is connected to a material leakage hole to collect the material. The collected material is discharged through the downward inclined discharge guide plate 10.

[0029] Specifically, such as Figure 3 As shown, a filter baffle 11 is inserted into the inner side of the guide duct 8, and a plug-in mounting block 12 is installed on the top of the filter baffle 11. The outer side of the plug-in mounting block 12 is made of rubber and can be squeezed and snapped onto the top of the guide duct 8, so that the filter baffle 11 can be installed conveniently and the clogged filter baffle 11 can be easily cleaned.

[0030] Specifically, such as Figure 3 As shown, a fan 13 is installed on the inner front end of the guide duct 8, and a clamping plate 14 is connected to the outer side of the fan 13. The clamping plate 14 has a threaded hole inside, and a screw is connected inside the positioning block 15. The fan 13 is clamped inside the guide duct 8 through a circular bracket with holes, and then the clamping plate 14 is clamped in the reserved groove of the guide duct 8. After reaching the position of the positioning block 15, it is connected and then fixed by the screw.

[0031] The cleaning and collection assembly includes a pull-out block 16, which is located at the rear end of the recycling bin 4. A collection hopper 17 is located at the front end of the pull-out block 16, and a fine groove plate 20 is located on the inner side of the collection hopper 17. The cleaning and collection assembly is used for cleaning and recycling plastic particles.

[0032] Specifically, such as Figure 4 As shown, an inclined support block 18 is fixedly connected to the bottom inner side of the collection hopper 17. An adhesive plate 19 is glued to the top of the inclined support block 18. A fine groove plate 20 is glued to the top of the adhesive plate 19. Fine grooves are provided on the fine groove plate 20. An adhesive plate is glued to the bottom of the fine groove plate 20. The distance between adjacent fine grooves is smaller than the inner diameter of the plastic particles. With the inclined setting of the inclined support block 18, dust in the plastic particles can be adsorbed and cleaned.

[0033] In this embodiment: the replaceable recycling bin 4 is easy to clean, the filter baffle 11 can block the material during the collection process and make the material gather. The filter baffle 11 and the fan 13 are easy to disassemble and clean. When collecting plastic particles in the collection hopper 17 inside the recycling bin 4, the material gathers through the guide of the inclined support block 18. The fine groove plate 20 with adhesive on the inner bottom layer adheres the fine dust in the plastic particles, which can improve the cleaning effect of the plastic particles.

[0034] The specific solution is as follows: During the use of injection molded parts, material is filled into the molding chamber 2 through the feeding box 3 for injection molding. The recycled material falls into the recycling box 4 and then into the guide air duct 8 through the collection trough 9. The rotation of the fan 13 facilitates the formation of a pressure difference inside, which is conducive to the collection of internal materials. The material is blocked by the filter baffle 11 and then guided by the discharge guide plate 10 to the inside of the collection hopper 17. The material is then transported from high to low on the inclined support block 18 and gathered by the guide of the inclined support block 18. The fine groove plate 20 with adhesive on the inner bottom layer adheres to the fine dust in the plastic particles, which facilitates the cleaning effect of the plastic particles and improves the subsequent recycling efficiency. The sliding block 6 slides inside the adjustment groove 5. The elastic force of the squeezing elastic element 7 makes the sliding block 6 lock on both sides, positioning the recycling box 4. The squeezing of the sliding blocks 6 on both sides makes it easy to remove the recycling box 4 for easy replacement and cleaning.
