Description

Technical Field

[0001] This utility model relates to the field of mechanical design, and in particular to an automatic cutting device. Background Technology

[0002] Cosmetic bottle caps and other products are often produced through injection molding. In order to improve production efficiency and economic benefits, injection molds are usually designed with multiple cavities so that multiple products can be molded in one injection process.

[0003] The multiple products obtained from the above injection molding process are often connected by a frame formed by the mold runner. These frames naturally need to be cut off in order to effectively obtain independent products, and the cutting of the frames is inseparable from the use of a cutting device.

[0004] However, existing cutting devices are difficult to effectively adapt to the removal of frames that are connected to multiple products at the same time, and the feeding and unloading of the products to be cut in the cutting process is difficult, resulting in low processing efficiency. Utility Model Content

[0005] The purpose of this invention is to provide an automatic cutting device that can solve one or more of the above-mentioned problems.

[0006] According to one aspect of the present invention, an automatic cutting device is provided, comprising a lifting mechanism, a cutting blade, a pressing mechanism, a feeding and discharging mechanism, a processing table, and a frame.

[0007] The lifting mechanism and the feeding / discharging mechanism are both mounted on the frame. The cutting blade and the pressing mechanism are both connected to the lifting mechanism. The processing table is connected to the feeding / discharging mechanism.

[0008] The processing table is equipped with product slots and frame slots. One frame slot is connected to multiple product slots, and a support block is provided on the product slot.

[0009] The product slot can be located below the pressing mechanism, and the connection between the frame slot and the product slot can be located below the cutting blade.

[0010] The beneficial effects of this utility model are as follows: This utility model allows products such as cosmetic bottle caps to be placed on the product slot of the processing table, supported by a support block. Simultaneously, the frame connected to the product is placed on the frame slot, and the feeding / discharging mechanism moves the product and frame slot to the processing table. This facilitates the movement of the product and frame slot to a cutable position, and allows for easy removal of the processed product after cutting. The separation of the product and frame is achieved by a lifting mechanism driving the cutting blade. A pressing mechanism is also included to press the product firmly during cutting, preventing displacement and ensuring cutting accuracy. This utility model facilitates the cutting and separation of multiple products and their connected frames with high cutting accuracy. It also features a corresponding feeding / discharging mechanism, high automation and processing efficiency, and good processing stability.

[0011] In some embodiments, the lifting mechanism includes a lifting cylinder, a connecting plate, and a connecting block. The lifting cylinder is connected to the connecting plate, the connecting block is connected to the connecting plate, and the cutting blade is connected to the connecting block. Since the lifting cylinder can drive the connecting plate to rise and fall, the cutting blade, which is connected to the connecting plate via the connecting block, can also rise and fall.

[0012] In some embodiments, the lifting mechanism includes a guide post and a guide sleeve. The guide sleeve is mounted on the connecting plate, and the guide post is mounted on the frame. The guide sleeve is slidably fitted onto the guide post. The guide post and guide sleeve facilitate limiting and guiding the movement of the connecting plate, thereby reducing the probability of the connecting plate moving in ways other than lifting.

[0013] In some embodiments, the pressing mechanism includes a pressing block, a damping plate, a spring, a connecting column, and a sleeve block. The sleeve block is mounted on the lifting mechanism and is slidably fitted onto the connecting column. The damping plate is connected to the connecting column, and the pressing block is connected to the damping plate. One end of the spring is connected to the damping plate, and the other end is connected to the lifting mechanism. The product slot can be located below the pressing block. The damping plate and spring facilitate the buffering of the impact generated when the pressing block initially contacts the product during pressing, reducing the probability of the pressing block damaging the product. Simultaneously, the spring effectively allows the lifting mechanism to continue driving the cutting blade downwards after the pressing block presses onto the product, thus avoiding obstruction to the movement of the cutting blade.

[0014] In some embodiments, the pressing mechanism includes an elastic pressure bar connected to a damping plate, the elastic pressure bar being positioned above the frame groove. The elastic pressure bar facilitates fixing the frame during cutting and allows for effective removal of the frame after cutting.

[0015] In some embodiments, the damping plate has holes through which the cutting blade can pass. The holes can limit the movement of the cutting blade, reducing the probability of blade displacement and effectively improving cutting accuracy.

[0016] In some embodiments, the feeding / discharging mechanism includes a linear drive device, a guide rail, and a slider. The linear drive device and the guide rail are both mounted on a frame, and the slider is slidably disposed on the guide rail. Both the linear drive device and the slider are connected to the processing table. The guide rail and slider limit and guide the movement of the processing table, reducing any deviation in the table's movement.

[0017] In some embodiments, the processing table is equipped with a drawer, the drawer having a receiving cavity located below and communicating with the frame cavity. The drawer can receive and collect the frame that falls from the frame cavity after cutting, facilitating subsequent processing of the cut frame. Attached Figure Description

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The present invention provides an automatic cutting device, comprising a lifting mechanism 1, a cutting blade 2, a pressing mechanism 3, a feeding and discharging mechanism 4, a processing table 5, and a frame 6.

[0025] The lifting mechanism 1 includes a lifting cylinder 11, a connecting plate 12, and a connecting block 13. The cylinder body of the lifting cylinder 11 is fixedly mounted on the frame 6 with screws, and the piston rod of the lifting cylinder 11 is fixedly connected to the connecting plate 12 through a connecting plate. The piston rod of the lifting cylinder 11 is set perpendicular to the horizontal plane, so that the lifting cylinder 11 can drive the connecting plate 12 to rise and fall. The connecting block 13 is fixedly connected to the bottom of the connecting plate 12 with screws, and one end of the cutter 2 is fixedly connected to the connecting block 13 with screws.

[0026] The lifting mechanism 1 also includes a guide column 14 and a guide sleeve 15. The two ends of the guide column 14 are fixedly mounted on the frame 6 by screws. The guide column 14 is set perpendicular to the horizontal plane, that is, the guide column 14 is set parallel to the piston rod of the lifting cylinder 11. The guide sleeve 15 is fixedly embedded in the connecting plate 12. The guide sleeve 15 is slidably sleeved on the guide column 14, so that the movement of the connecting plate 12 is limited and guided by the guide column 14.

[0027] The pressing mechanism 3 includes a pressing block 31, a damping plate 32, a spring 33, a connecting column 34, a sleeve block 35, and an elastic pressing rod 36. The sleeve block 35 is fixedly embedded in the connecting plate 12 of the lifting mechanism 1. The sleeve block 35 is relatively slidably sleeved on the connecting column 34. The damping plate 32 is fixedly connected to the bottom of the connecting column 34 by screws. The pressing block 31 is fixedly connected to the bottom of the damping plate 32. The spring 33 is sleeved on the connecting column 34. One end of the spring 34 is fixedly connected to the damping plate 32 by screws, and the other end of the spring 34 is fixedly connected to the connecting plate 12 of the lifting mechanism 1 by screws. In addition, the elastic pressing rod 36 is also fixedly connected to the bottom of the damping plate 32 by screws.

[0028] Under normal conditions, the height of the pressure block 31 is lower than the height of the bottom of the cutting blade 2, and the damping plate 32 has a hole 321. The size of the hole 321 is similar to that of the cutting blade 2, and the cutting blade 2 can pass through the hole 321.

[0029] The feeding / discharging mechanism 4 includes a linear drive device 41, a guide rail 42, and a slider 43. The linear drive device 41 can be a rodless cylinder or a servo motor, etc. The linear drive device 41 and the guide rail 42 are both fixedly mounted on the frame 6 by screws. The guide rail 42 is set parallel to the horizontal plane. The slider 43 is slidably sleeved on the guide rail 42. The moving block on the linear drive device 41 and the slider 43 are both fixedly connected to the bottom of the processing table 5 by screws, so that the processing table 5 can move laterally.

[0030] The processing table 5 is provided with product slots 51 and frame slots 52. One frame slot 52 can be connected to multiple product slots 51. In this embodiment, one frame slot 52 can be connected to four product slots 51. The product slots 51 are provided with support blocks 511.

[0031] The side of the processing table 5 is also provided with a drawer 53. The drawer 53 can be pulled out from the main body of the processing table 5 when needed. The drawer 53 is provided with a receiving cavity, which can be located below the frame cavity 52 and is connected to the frame cavity 52.

[0032] Driven by the feeding and discharging mechanism 4, the processing table 5 can be moved, and the product groove 51 on the processing table 5 can be located below the pressing block 31 of the pressing mechanism 3, the frame groove 52 can be located below the elastic pressing rod 36, and the connection position between the frame groove 52 and the product groove 51 can be located below the cutting blade 2.

[0033] When in use, the linear drive device 41 on the feeding and discharging mechanism 4 can drive the processing table 5 to move, so that the processing table 5 is not located below the lifting mechanism 1, which facilitates the feeding of the product 10 to be cut.

[0034] The product 10 to be cut can preferably be a cosmetic bottle cap. The product 10 to be cut and the frame 20 connected to the product 10 can be transported to the processing table 5 by an external robot or other device, so that the product 10 is located on the product groove 51 and the frame 20 is located on the frame groove 52.

[0035] Then the linear drive device 41 on the feeding and discharging mechanism 4 can drive the processing table 5 to move, so that the product groove 51 on the processing table 5 can be located below the pressure block 31 of the pressure mechanism 3, the frame groove 52 can be located below the elastic pressure rod 36, and the connection position between the frame groove 52 and the product groove 51 can be located below the cutting blade 2.

[0036] Then, the lifting cylinder 11 on the lifting mechanism 1 can drive the connecting plate 12 to move down, and the pressure block 31 and the cutting blade 2 will also move down accordingly. The pressure block 31 will first contact the product 10 on the product slot 51, and the elastic pressure rod 36 will contact the frame 20 on the frame slot 52, so that the pressure block 31 can press the product 10 and the elastic pressure rod 36 can press the frame 20.

[0037] As the lifting cylinder 11 continues to move the connecting plate 12 downwards, the spring 33 can be compressed, allowing the connecting plate 12 and the damping plate 32 to move relative to each other. The pressure block 31 maintains pressure on the product 10, and the elastic pressure rod 36 maintains pressure on the frame 20. The cutting blade 2 can then continue to move downwards to cut the connection between the product 10 and the frame 20, separating the product 10 from the frame 20. After separation, the frame 20, under the pressure of gravity and the elastic pressure rod 36, falls from the frame slot 52 into the receiving cavity of the drawer 53 for collection. The product 10, supported by the support block 511, remains in the product slot 51.

[0038] Then, the lifting mechanism 1 drives the connecting plate 12 to rise and reset, that is, the pressure block 31, the elastic pressure rod 36 and the cutting blade 2 are reset. Then, the linear drive device 41 on the feeding and discharging mechanism 4 can drive the processing table 5 to move. The processing table 5 moves away from below the lifting mechanism 1, making it convenient for the user to take the product out of the product slot 51.

[0039] In addition, to further improve processing efficiency, in this embodiment, the processing table 5 is provided with four frame slots 52, and each frame slot 52 is connected to four product slots 51, resulting in a total of sixteen connection positions between frame slots 52 and product slots 51. Accordingly, there are also preferably sixteen cutting blades 2 and sixteen pressing blocks 31, so that during one cutting process, the sixteen pressing blocks can press on the sixteen products 10 at the same time, and the sixteen cutting blades 2 can cut the connection positions between the sixteen products 10 and the frame 20 at the same time.

[0040] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
