Description

Technical Field

[0001] The utility model belongs to the technical field of plastic product processing, and particularly relates to a gate cutting device. Background Art

[0002] The plastic process usually heats plastic particles to a fluid state and forms them into required products by means of injection technology with the help of a mold. Because plastics are easy to form, light in weight, rich in colors, beautiful and applicable, the development of the mold is directly related to the plastic industry. When using an injection molding machine to manufacture products, the mold used must be based on the designed product shape and its size. Currently, for the gate cutting device used for plastic products, the gate of the plastic product is cut by a cutting knife.

[0003] For example, in a Chinese utility model with the publication number CN213891085U and the name of a gate cutting device for plastic products, it specifically includes a frame. The inner side of the top of the frame is fixedly connected with an electric telescopic shaft, and the lower end of the electric telescopic shaft is fixedly connected with a fixing plate. The left side of the lower end of the fixing plate is fixedly connected with a cutting knife. The left side of the upper end of the frame is fixedly connected with a support frame. The upper part of the front end of the support frame is rotatably connected with a rotating shaft, and the front end of the rotating shaft is fixedly connected with a turntable. Six mounting plates are fixedly connected to the periphery of the turntable, and gates are opened on the outer sides of the mounting plates. Although the above prior art can continuously cut multiple plastic products, since the cutting edge of the cutting knife faces downward, during a cutting process, the cutting knife needs to reciprocate up and down for one cycle, resulting in a non-cutting state during the return journey, and the cutting efficiency is limited. Therefore, a gate cutting device is needed now. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a gate cutting device with a simple structure and reasonable design to solve the above problems.

[0005] The utility model realizes the above purpose through the following technical solutions:

[0006] A gate cutting device includes a base. A fixed bracket and two vertical plates located on one side of the fixed bracket are fixedly connected to the upper side of the base. A plurality of connecting rods are rotatably arranged at the upper end of the fixed bracket. A driving mechanism for driving the plurality of connecting rods to rotate simultaneously is arranged on one side of the fixed bracket. Fixing mechanisms for fixing plastic products are arranged at one ends of the plurality of connecting rods. A double-sided cutting knife is vertically slidably arranged between the two vertical plates. A reciprocating driving assembly for driving the double-sided cutting knife to reciprocate vertically is arranged at the upper ends of the two vertical plates.

[0007] As a further optimization solution of the utility model, the reciprocating drive assembly includes a second servo motor fixedly arranged at the upper end of the vertical plate. The output end of the second servo motor is fixedly connected with a turntable. An eccentric rod is fixedly arranged at the eccentric position of the turntable. One end of the eccentric rod is rotatably provided with a transmission rod. The lower side of the transmission rod is connected with a double-sided cutter through a guiding assembly.

[0008] As a further optimization solution of the utility model, the guiding assembly includes a sliding groove opened in the middle of the vertical plate. The inner side of the sliding groove is slidably connected with a slider connected with the double-sided cutter. The upper side of the slider is rotatably provided with a crank rotatably connected with the lower side of the transmission rod.

[0009] As a further optimization solution of the utility model, the driving mechanism includes a rotating shaft rotatably arranged at the upper end of the fixed bracket. A fixed sleeve is fixedly sleeved in the middle of the rotating shaft. A plurality of the connecting rods are evenly arranged on the circumferential surface of the fixed sleeve.

[0010] As a further optimization solution of the utility model, the fixing mechanism includes a clamping bracket fixedly arranged at one end of the connecting rod. One end of the clamping bracket is fixedly connected with an electric telescopic rod. The output end of the electric telescopic rod is fixedly connected with a clamping plate for fixing the plastic product on the clamping bracket.

[0011] As a further optimization solution of the utility model, a finished product collecting box located below the clamping bracket and a waste collecting box located below the double-sided cutter are arranged on the upper side of the base.

[0012] The beneficial effects of the utility model are as follows: In the utility model, the second servo motor drives the turntable to rotate, so that the eccentric rod thereon drives the transmission rod to move, and further drives the crank on the lower side of the transmission rod to pull the slider to reciprocate up and down on the inner side of the sliding groove, so that the double-sided cutter on one side of the slider reciprocates up and down. Since the double-sided cutter can cut on both the upper and lower sides, the double-sided cutter can complete the cutting of the gates of two plastic products during the up and down reciprocating movement, further improving the cutting efficiency.

[0018] Embodiment

[0019] As Figure 1 shown, a gate trimming device includes a base 1. A fixed bracket 3 and two vertical plates 17 located on one side of the fixed bracket 3 are fixedly connected to the upper side of the base 1. A plurality of connecting rods 10 are rotatably arranged at the upper end of the fixed bracket 3. A driving mechanism for driving a plurality of connecting rods 10 to rotate simultaneously is arranged on one side of the fixed bracket 3. The driving mechanism includes a rotating shaft 4 rotatably arranged at the upper end of the fixed bracket 3. A fixed sleeve 9 is fixedly sleeved in the middle of the rotating shaft 4. A plurality of connecting rods 10 are evenly arranged on the circumferential surface of the fixed sleeve 9.

[0020] As Figure 2 、 Figure 3 shown, a fixing mechanism for fixing plastic products is arranged at one end of each of the plurality of connecting rods 10. A double-sided cutter 20 is vertically slidably arranged between the two vertical plates 17. The fixing mechanism includes a clamping frame 7 fixedly arranged at one end of the connecting rod 10. An electric telescopic rod 5 is fixedly connected to one end of the clamping frame 7. A clamping plate 6 for fixing the plastic product on the clamping frame 7 is fixedly connected to the output end of the electric telescopic rod 5. A finished product collection box 2 located below the clamping frame 7 and a waste collection box 18 located below the double-sided cutter 20 are arranged on the upper side of the base 1. The cut finished products can be collected through the finished product collection box 2. When the plastic product finishes cutting the gate and moves above the finished product collection box 2, the electric telescopic rod 5 drives the clamping plate 6 to return, so that the cut plastic product falls into the finished product collection box 2, completing automatic collection and eliminating the need for manual unloading, improving the unloading efficiency. The waste collection box 18 can collect the cut waste.

[0021] As Figure 2 、 Figure 3As shown in the figure, a reciprocating drive assembly for driving the double-sided cutter 20 to move vertically back and forth is provided at the upper ends of the two vertical plates 17. The reciprocating drive assembly includes a second servo motor 13 fixedly arranged at the upper end of the vertical plate 17. The output end of the second servo motor 13 is fixedly connected with a turntable 12. An eccentric rod 19 is fixedly arranged at the eccentric position of the turntable 12. One end of the eccentric rod 19 is rotatably provided with a transmission rod 11. A chute 16 is opened in the middle of the vertical plate 17. A slider 15 connected to the double-sided cutter 20 is slidably connected to the inner side of the chute 16. A crank 14 rotatably connected to the lower side of the transmission rod 11 is rotatably provided on the upper side of the slider 15. During use, the rotation of the turntable 12 drives the eccentric rod 19 to rotate together, thereby driving the transmission rod 11 to move, pulling the crank 14 to swing back and forth, driving the slider 15 to move up and down reciprocally, and enabling the double-sided cutter 20 to move up and down reciprocally. The double-sided cutter 20 can cut two plastic products with one up and down reciprocating movement, improving the cutting efficiency.

[0022] It should be noted that for this trimming gate device, during use, first place the plastic product into the clamping frame 7, then drive the clamping plate 6 through the electric telescopic rod 5 to fix the plastic product on the clamping frame 7, and then drive the plurality of clamping frames 7 to rotate through the first servo motor 8. When the clamping frame 7 rotates horizontally between the two vertical plates 17, the second servo motor 13 can be driven to drive the turntable 12 to rotate, so that the eccentric rod 19 thereon drives the transmission rod 11 to move, and further drives the crank 14 on the lower side of the transmission rod 11 to pull the slider 15 to move up and down reciprocally inside the chute 16, enabling the double-sided cutter 20 on one side of the slider 15 to move up and down reciprocally. Since the double-sided cutter 20 can cut both up and down, the double-sided cutter 20 can complete the cutting of the gates of two plastic products during the up and down reciprocating movement.

[0023] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
