Description

Technical Field

[0001] The present invention relates to the field of plastic parting line processing, and in particular to a plastic parting line removal machine. Background Art

[0002] The parting line, also known as the flash line, is the visible mark left after the excess plastic flows out of the mold joint and the overflow is cut off. It is sometimes called the mold mark or interface line. It also refers to the seam on the plastic part or casting caused by the material flowing into the gap between the mold parts, or the joint seam under the main model of the mold, which is used to indicate that the mold is divided into two halves or several parts at this point.

[0003] After plastic products are produced, there will generally be plastic mold lines. In order to ensure the quality and appearance of the products, the plastic mold lines on the plastic products will be removed.

[0004] Currently, the plastic parting lines on the surface of plastic products are frozen to make them fall off automatically. This can effectively remove the plastic parting lines on the surface of plastic products, but the plastic products will continue to accumulate at the bottom when stirred, which can easily lead to the plastic products not being able to fully contact with the cold air. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art that the plastic product cannot be fully contacted with cold air, which easily affects the removal of the mold line, the present invention provides a plastic mold line removal machine that can ensure that the plastic product is fully contacted with cold air during stirring.

DETAILED DESCRIPTION

[0032] The present invention will be further described below with reference to the accompanying drawings and examples.

[0033] Example 1

[0034] A plastic parting line removal machine, such as Figures 1 to 3 As shown, it includes a support 1, a fixed frame 2, a collecting frame 3, a mixing box 4, a cooler 5, a discharge frame 6 and a baffle 7. The fixed frame 2 is fixedly connected to the support 1, the collecting frame 3 is slidably connected to the fixed frame 2, the mixing box 4 is fixedly connected to the support 1, the cooler 5 is installed on both sides of the top of the mixing box 4, the cooler 5 is connected to the mixing box 4 and transports cold air inward, the discharge frame 6 is connected and connected to the bottom of the mixing box 4, the baffle 7 is slidably connected to the discharge frame 6, and also includes a stirring mechanism 8 for making the plastic product fully contact with the cold air and a filtering mechanism 9 for removing impurities on the plastic product.

[0035] like Figure 4 As shown, the stirring mechanism 8 includes a rotating rod 801, a stirring drum 802, a partition plate 803, a push block 804 and a motor 805. The rotating rod 801 is rotatably connected to the stirring box 4, the stirring drum 802 is fixed in the stirring box 4, the stirring drum 802 rotates in the stirring box 4, the partition plate 803 is fixed on the rotating rod 801, the push block 804 is slidably connected to the partition plate 803, and the rear end of the rotating rod 801 is connected to the output shaft of the motor 805.

[0036] like Figure 5 and Figure 6As shown, the filtering mechanism 9 includes a filter block 901, a mounting frame 902, a slide rod 903, a scraper 904, a first return spring 905 and a blanking frame 906. The filter block 901 is fixed to the fixed frame 2, the mounting frame 902 is connected to the right side of the filter block 901 by bolts, the left end of the slide rod 903 is connected to the filter block 901, the right end of the slide rod 903 is connected to the mounting frame 902, the scraper 904 is slidably connected to the slide rod 903, a first return spring 905 is connected between the scraper 904 and the mounting frame 902, and the blanking frame 906 is connected to and communicated with the bottom of the filter block 901.

[0037] First, the staff pours the plastic product into the mixing box 4, and the plastic product enters the mixing drum 802. Then the cooler 5 is started, and the cooler 5 sends cold air to the mixing drum 802 for cooling. Then the motor 805 is started, and the motor 805 drives the rotating rod 801 and the partition plate 803 to rotate. The rotation of the partition plate 803 drives the push block 804 to rotate together. When the partition plate 803 brings the push block 804 upward, the push block 804 falls down under the action of gravity, and the push block 804 pushes the plastic product on the upper part of the mixing box 4 to the bottom, so that the plastic product in the mixing box 4 automatically moves up and down, which helps When the plastic product is cooled evenly, after the cooling process is completed, the baffle 7 is pulled out, and the plastic product falls from the discharge frame 6 onto the filter block 901. The staff then manually pulls the scraper 904 to the right, and then releases the scraper 904. The scraper 904 moves to the left and resets under the action of the first reset spring 905. Then the scraper 904 is repeatedly pulled, so that the scraper 904 continuously scrapes the plastic product on the filter block 901, so that the plastic product is scraped to the left and right sides and then falls from the blanking frame 906, while the mold line and other impurities fall from the filter hole 901a of the filter block 901 into the collection frame 3.

[0038] Example 2

[0039] On the basis of Example 1, Figure 7 and Figure 8 As shown, it also includes a cleaning mechanism 10, which includes a rotating pressure rod 1001, an arcuate slide rail 1002, a first fixed rod 1003, a sliding plate 1004, a cleaning brush 1005 and a second return spring 1006. The rotating pressure rod 1001 is fixed to the front and rear ends of the rotating rod 801, and the arcuate slide rail 1002 is symmetrically fixed to the left and right sides of the mixing box 4. The first fixed rod 1003 is fixed to the arcuate slide rail 1002, and the sliding plate 1004 is slidably connected to the arcuate slide rail 1002. A cleaning brush 1005 is fixed to the inner side of the sliding plate 1004, and a second return spring 1006 is connected between the sliding plate 1004 and the first fixed rod 1003.

[0040] When the motor 805 drives the rotating rod 801 to rotate, the rotating pressure rod 1001 rotates along with the rotating rod 801. The rotation of the rotating rod 801 will push the sliding plate 1004 to move up and down along the arc slide rail 1002 with the cleaning brush 1005. The second reset spring 1006 is used to automatically reset the sliding plate 1004, and the cleaning brush 1005 moves up and down to clean the gap of the mixing drum 802 to prevent impurities from being stuck in the gap of the mixing drum 802.

[0041] like Figure 9 and Figure 10 As shown, it also includes a driving mechanism 11, which includes an arc plate 1101, a connecting block 1102 and a wedge block 1103. The arc plate 1101 is fixedly connected to the front and rear sides of the right sliding plate 1004, the connecting block 1102 is fixedly connected to the scraper 904, the connecting block 1102 is slidably connected to the arc plate 1101, and the wedge block 1103 is slidably connected to the connecting block 1102.

[0042] When the rotating pressure rod 1001 rotates following the rotating rod 801, the rotating pressure rod 1001 will push the wedge block 1103 and the connecting block 1102 to move right. The rightward movement of the connecting block 1102 will drive the scraper 904 to move right automatically, so that the scraper 904 automatically scrapes and filters the plastic products on the filter block 901, saving time and effort. When the scraper 904 moves to the narrower part of the rightmost arc plate 1101, the wedge block 1103 slides inward in the connecting block 1102. When the rotating pressure rod 1001 is separated from the wedge block 1103, the connecting block 1102 moves to the left and resets under the action of the first reset spring 905, and the wedge block 1103 is pushed up and reset by the wider part of the arc plate 1101.

[0043] like Figure 11 As shown, a diversion mechanism 12 is also included, and the diversion mechanism 12 includes a diversion box 1201, a rotating plate 1202 and a connecting pipe 1203. The diversion box 1201 is fixedly connected to the front end of the rotating rod 801, and the rotating plate 1202 is fixedly connected to the rotating rod 801. The rotating plate 1202 can rotate in the diversion box 1201, and the connecting pipe 1203 is symmetrically fixed to the left and right sides of the diversion box 1201. The connecting pipe 1203 connects and communicates the diversion box 1201 and the stirring box 4.

[0044] When the motor 805 drives the rotating rod 801 to rotate, the rotating plate 1202 rotates along with the rotating rod 801. The rotating plate 1202 rotates in the diversion box 1201 and transports the cold air above the mixing box 4 to the bottom, so that all plastic products in the mixing drum 802 can be in contact with the cold air and cooled.

[0045] like Figure 12As shown, a buffer mechanism 13 is also included, and the buffer mechanism 13 includes a square plate 1301, a second fixed rod 1302, and a buffer spring 1303. The second fixed rod 1302 is slidably connected to the bottom wall of the blanking frame 906, and the square plate 1301 is fixed to the upper end of the second fixed rod 1302. A buffer spring 1303 is connected between the second fixed rod 1302 and the bottom surface of the blanking frame 906.

[0046] When the scraper 904 in the filtering mechanism 9 scrapes the plastic product with the mold line and impurities removed to the blanking frame 906, the plastic product falls from the blanking frame 906 onto the square plate 1301, and the buffer spring 1303 can slow down the collision between the plastic product and the square plate 1301 to prevent the plastic product from being damaged when it falls.

[0047] like Figure 2 and 12 As shown, a handle 14 is also included, and the handle 14 is fixed to the front side of the collecting frame 3.

[0048] When the plastic product is cooled and filtered by the filtering mechanism 9, the impurities on the plastic product fall into the collecting frame 3. The staff pulls the handle 14 to pull out the collecting frame 3 for cleaning. The handle 14 makes it easier to pull out the collecting frame 3.
