Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, specifically to a device for removing burrs from blow molding parts. Background Technology

[0002] Blow molding is a process in which liquid plastic is sprayed out by a blow molding machine and then blown into a mold cavity of a certain shape by the air force of the machine, thus making the product. However, the mold cavity is generally formed by two molds joined together. Therefore, during the blow molding process, the molten plastic will form flash at the seam where the two molds are joined. In order to ensure the appearance of the product, the flash needs to be removed.

[0003] Chinese patent CN218535327U discloses a device for removing flash from blow-molded products by cutting them completely. It mainly includes a base plate and a motor mounted on the base plate. A disc is mounted on the output end of the motor, and a placement plate is mounted on the disc. An adjustment component is also mounted on the base plate, and a blade is mounted on the output end of the adjustment component. This application, by setting a blade tip and a grinding head, can automatically process the flash of blow-molded products, ensuring uniform flash removal and simultaneously grinding the flash to guarantee complete flash removal. However, the aforementioned patent requires multiple sets of locking pins to fix the blow-molded workpiece, preventing rapid fixation and resulting in a longer overall processing time, affecting flash removal efficiency. Therefore, we propose a device for removing flash from blow-molded products by cutting them completely. Utility Model Content

[0004] The purpose of this invention is to provide a device for removing burrs from blow-molded parts that cuts completely, in order to solve the problem mentioned in the background art that when fixing blow-molded workpieces, multiple sets of locking pins are required, which cannot quickly fix the workpieces, resulting in a long overall processing time and affecting the efficiency of burr removal.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for removing flash from blow-molded parts, comprising a base plate, a first motor, an adjusting rod, a connecting block, a connecting mechanism, and a cutter. The first motor is fixedly connected to the top left of the base plate, the adjusting rod is fixedly connected to the top right of the base plate, the connecting block is screwed to the left end of the adjusting rod, and the cutter is connected to the top of the connecting block through the connecting mechanism. A fixing mechanism is fixedly connected to the output shaft end of the first motor. The fixing mechanism includes a housing, a second motor, a turntable, a connecting column, a connecting rod, a sliding rod, and a slider. The system comprises a connecting seat, a fixing block, and a clamping seat. A housing is fixedly connected to the output shaft end of the first motor. A second motor is fixedly connected to the center of the bottom of the inner cavity of the housing. A turntable is fixedly connected to the output shaft end of the second motor. A connecting column is symmetrically fixedly connected to the top of the turntable. A connecting rod is rotatably connected to the outer wall of the connecting column. A sliding rod is symmetrically fixedly connected to the top between the front and rear sides of the housing. A slider is symmetrically slidably connected to the outer wall of the sliding rod. A connecting seat is fixedly connected to the center of the bottom of the slider. A fixing block is fixedly connected to the center of the top of the slider. A clamping seat is fixedly connected to the top of the fixing block.

[0006] As a further description of the above technical solution:

[0007] The input terminals of both the first motor and the second motor are electrically connected to the output terminal of an external power supply, and one end of the connecting rod is rotatably connected to the inside of the connecting seat.

[0008] As a further description of the above technical solution:

[0009] A through groove is provided through the top center of the outer casing, and the fixing block is located inside the through groove.

[0010] As a further description of the above technical solution:

[0011] The connecting mechanism includes a slot, a push rod, a connecting plate, a circular plate, a connecting spring, a locking block, a pressing shell, and a slot. The top left of the connecting block has a slot, and the push rod is slidably connected through the bottom of the front and rear sides of the slot. The opposite ends of the two push rods are fixedly connected to the connecting plate, and the far ends of the two push rods are fixedly connected to the circular plate. A connecting spring is sleeved on the outside of the push rod. The top of the far sides of the two connecting plates are fixedly connected to the locking block. The bottom of the cutter is fixedly connected to the pressing shell, and the top of the front and rear sides of the inner cavity of the pressing shell has a slot.

[0012] As a further description of the above technical solution:

[0013] The two ends of the connecting spring are fixedly connected to the opposite sides of the circular plate and the connecting block.

[0014] As a further description of the above technical solution:

[0015] The bottom of the front and rear sides of the inner cavity of the extrusion shell is provided with an inclined surface, and the top of the card block is also provided with an inclined surface.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This complete blow molding flash removal device, through the start of the second motor, drives the turntable to deflect, thereby causing the connecting rod to deflect and the connecting seats to move closer together. This causes the slider to slide on the sliding rod, and the slider to drive the fixed blocks to move closer together, so that the clamping seat clamps the workpiece. This makes clamping and fixing faster, avoids the use of multiple fastening pins for fixing, saves fixing time, and improves the overall removal efficiency.

[0018] 2. This complete blow molding flash removal device allows for easy replacement of the cutter. When the cutter needs to be replaced, pressing the lever brings the connecting plates closer together, causing the locking block to disengage from the slot, releasing the extrusion shell, and allowing the cutter to be removed. Then, installing the new cutter causes the inclined surface inside the extrusion shell to press the locking block, bringing the connecting plates closer together. When the locking block aligns with the slot, a connecting spring causes the locking block to embed into the slot, completing the replacement. This facilitates cutter replacement, saving time and effort, improving convenience, and enhancing the device's practicality. Attached Figure Description

[0028] This invention provides a device for removing burrs from blow molding products, enabling faster clamping and fixing, avoiding the need for multiple fastening pins, saving fixing time, and improving overall removal efficiency. Please refer to [link / reference]. Figure 1-5 It includes a base plate 100, a first motor 200, an adjusting rod 400, a connecting block 500, a connecting mechanism 600, and a cutter 700;

[0029] Please refer to it again. Figure 1 The base plate 100 is used to mount the first motor 200, the adjusting rod 400, the connecting block 500, the connecting mechanism 600, and the cutter 700;

[0030] Please refer to it again. Figure 1 The first motor 200 is fixedly connected to the top left of the base plate 100 for mounting the fixing mechanism 300. The adjusting rod 400 is fixedly connected to the top right of the base plate 100 for mounting the connecting block 500. The connecting block 500 is screwed to the left end of the adjusting rod 400 for mounting the cutter 700. The cutter 700 is connected to the top of the connecting block 500 through the connecting mechanism 600. The output shaft end of the first motor 200 is fixedly connected to the fixing mechanism 300.

[0031] Please refer to it again. Figure 2 The fixing mechanism 300 includes a housing 310, a second motor 320, a turntable 330, a connecting column 340, a connecting rod 350, a sliding rod 360, a slider 370, a connecting seat 380, a fixing block 390, and a clamping seat 391.

[0032] Please refer to it again. Figure 2 The output shaft end of the first motor 200 is fixedly connected to the housing 310, the bottom center of the inner cavity of the housing 310 is fixedly connected to the second motor 320, the output shaft end of the second motor 320 is fixedly connected to the turntable 330, the top of the turntable 330 is symmetrically fixedly connected to the connecting column 340, and the outer side wall of the connecting column 340 is rotatably connected to the connecting rod 350.

[0033] Please refer to it again. Figure 2 A slide rod 360 is symmetrically fixedly connected to the top between the front and rear sides of the outer casing 310. A slider 370 is symmetrically slidably connected to the outer side wall of the slide rod 360. A connecting seat 380 is fixedly connected to the bottom center of the slider 370. A fixing block 390 is fixedly connected to the top center of the slider 370. A clamping seat 391 is fixedly connected to the top of the fixing block 390.

[0034] In summary, by starting the second motor 320, the turntable 330 is driven to deflect, which causes the connecting rod to deflect 350, causing the connecting seats 380 to move closer together. This causes the slider 370 to slide on the sliding rod 360, which in turn causes the slider 370 to move the fixing blocks 390 closer together. This allows the clamping seat 391 to clamp the workpiece, making clamping and fixing faster, avoiding the need for multiple fastening pins, saving fixing time, and improving the overall removal efficiency.

[0035] Please refer to it again. Figure 2The input terminals of the first motor 200 and the second motor 320 are both electrically connected to the output terminal of the external power supply, and one end of the connecting rod 350 is rotatably connected to the inside of the connecting seat 380.

[0036] Please refer to it again. Figure 2 A through slot is provided in the top center of the outer casing 310, and the fixing block 390 is located inside the through slot.

[0037] Please refer to it again. Figure 3-5 The connecting mechanism 600 includes a slot 610, a push rod 620, a connecting plate 630, a circular plate 640, a connecting spring 650, a locking block 660, a pressing shell 670, and a slot 680. The top left of the connecting block 500 has a slot 610. The push rod 620 is slidably connected through the bottom of the front and rear sides of the slot 610. The opposite ends of the two push rods 620 are fixedly connected to the connecting plate 630. The far ends of the two push rods 620 are fixedly connected to the circular plate 640. The connecting spring 650 is sleeved on the outside of the push rod 620. The top of the far sides of the two connecting plates 630 are fixedly connected to the locking block 660. The bottom of the cutter 700 is fixedly connected to the pressing shell 670. The top of the front and rear sides of the inner cavity of the pressing shell 670 has a slot 680.

[0038] Please refer to it again. Figure 3 The two ends of the connecting spring 650 are fixedly connected to the opposite sides of the circular plate 640 and the connecting block 500.

[0039] Please refer to it again. Figure 5 The bottom of the front and rear sides of the inner cavity of the extrusion shell 670 is provided with an inclined surface, and the top of the clamping block 660 is also provided with an inclined surface.

[0040] In summary, when the cutter 700 needs to be replaced, press the lever 620 to bring the connecting plates 630 closer together, causing the locking block 660 to disengage from the slot 680, releasing the fixation of the extrusion shell 670, and removing the cutter 700. Then, install the new cutter 700, causing the inclined surface inside the extrusion shell 670 to press the locking block 660, bringing the connecting plates 630 closer together. When the locking block 660 is aligned with the slot 680, the connecting spring 650 causes the locking block 660 to be embedded in the slot 680, completing the replacement. This facilitates the replacement of the cutter 700, saves time and effort, improves the convenience of replacement, and enhances the practicality of the device.

[0041] In practical use, those skilled in the art first place the workpiece at the top center of the outer casing 310, then start the second motor 320. The start of the second motor 320 causes the turntable 330 to deflect, thereby causing the connecting rod to deflect 350, which in turn causes the connecting seats 380 to move closer together. This causes the slider 370 to slide on the sliding rod 360, and the slider 370 causes the fixing blocks 390 to move closer together, allowing the clamping seat 391 to clamp the workpiece. Then, by adjusting the adjusting rod 400, the cutter 700 is positioned at the flash of the workpiece. The first motor 200 is then started to rotate the workpiece, and the cutter 700 removes the flash. When the cutter 700 is worn and needs replacement, the push-button lever 620 is pressed. The connecting plates 630 move closer together, causing the locking block 660 to exit the slot 680, releasing the fixation of the extrusion shell 670, and removing the cutter 700. Then, a new cutter 700 is installed, causing the extrusion shell 670 to be embedded in the slot 610. The inclined surface inside the extrusion shell 670 presses against the locking block 660, causing the connecting plates 630 to move closer together. This causes the push rod 620 to move the circular plates 640 closer together, pressing the connecting spring 650. When the locking block 660 aligns with the slot 680, the reset of the connecting spring 650 causes the push rod 620 to reset, resetting the connecting plate 630, causing the locking block 660 to be embedded in the slot 680, fixing the extrusion shell 670, and thus fixing the cutter 700, completing the replacement.
