Description

Technical Field

[0001] This utility model relates to the field of plastic processing equipment technology, and in particular to a cutting edge machine for plastic products. Background Technology

[0002] Nowadays, there are many manufacturing processes for plastic products, such as injection molding, blow molding, and thermoforming. After the production of some cylindrical products, rough edges or irregular edges appear at the opening, so they need to be cut again by an edge trimming machine.

[0003] In actual processing, the cylindrical product is placed with its opening facing down on the positioning post of the workbench, and then a pressure block is pressed on top of the product to fix it in place. Finally, the cutting blade is started to approach the product and rotate to cut it. After cutting, the annular waste and the product are often tightly fitted onto the positioning post under the pressure of the pressure block. The operator needs to remove the product and the annular waste from the positioning post one by one from bottom to top. This operation is cumbersome and inconvenient. The cut edge of the annular waste is relatively sharp and inconvenient to remove. The accumulation of waste will affect the positioning and cutting efficiency of subsequent products. Therefore, based on the above problems, an edge trimming machine that can help operators to easily and quickly remove the product and the annular waste has high practical application value. This utility model provides an edge trimming machine for plastic products to meet the needs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a cutting machine for plastic products. By setting a positioning component, it can not only assist the operator in completing the cutting operation of irregular edges and rough edges of the product, but also push the cut product and the ring-shaped waste generated by cutting upward along the outer wall of the positioning column for easy handling. In the process of pushing the ring-shaped waste upward, the ring-shaped waste is cut into strips, avoiding the accumulation of ring-shaped waste and facilitating subsequent centralized collection and processing, thereby improving the cutting and production efficiency of the product.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A cutting machine for plastic products includes a cutting table, a motor fixedly connected to the bottom of the cutting table, a first connecting block fixedly connected to the output end of the motor, and a second connecting block fixedly connected to the top of the first connecting block; and a positioning component for assisting the operator in completing the product cutting operation, the positioning component being connected to the cutting table and the second connecting block respectively.

[0006] Optionally, the positioning component includes a positioning post fixedly connected to the top of the second connecting block, a first cylinder, a fixing frame and a mounting base fixedly connected to the top of the cutting table, a cutting blade rotatably connected to the inner side wall of the positioning post near the bottom, and a waste collection tray screwed to the output end of the first cylinder.

[0007] Optionally, the waste collection tray is sleeved on the outer wall of the positioning column, and the top of the waste collection tray is provided with an annular groove for accommodating annular waste.

[0008] Optionally, the outer wall of the positioning post near the bottom and the top of the waste collection tray are respectively provided with a first storage groove and a second storage groove that match the outline of the cutting blade.

[0009] Optionally, a limiting groove is provided on one side of the cutting blade, and the top of the cutting blade is U-shaped.

[0010] Optionally, a limiting rod is fixedly connected to the inner side wall of the second storage groove, and the limiting rod slides along the limiting groove.

[0011] Optionally, a third cylinder is fixedly connected to the top of the fixing frame, a third connecting block is fixedly connected to the output end of the third cylinder, and a circular pressure block is fixedly connected to the bottom of the third connecting block.

[0012] Optionally, a second cylinder is fixedly connected to the top of the mounting base, and a cutting blade is screwed onto the outer wall of the output end of the second cylinder.

[0013] Compared with the prior art, this utility model has at least the following beneficial effects: In the above-mentioned solution, the plastic product edge cutting machine provided in this application can not only assist the operator in completing the cutting operation of irregular edges and burrs on the product, but also push the cut product and the annular waste generated by cutting upward along the outer wall of the positioning column for easy handling. In the process of pushing the annular waste upward, the annular waste is cut into strips, avoiding the accumulation of annular waste and facilitating subsequent centralized collection and processing, thereby improving the cutting and production efficiency of the product.

[0014] By setting up positioning posts, waste collection trays, and a first cylinder, the annular waste generated during the cutting operation can be collected in an annular groove. As the first cylinder pushes, the waste moves upward with it. During the movement, the waste collection tray also pushes the product tightly fitted on the positioning posts upward together, making it convenient for the operator to pick up.

[0015] By setting up a cutting blade, a first collection slot, and a second collection slot, when the first cylinder pushes the waste collection tray to slide upward along the positioning column, the limiting rod in the second collection slot will slide in the limiting slot of the cutting blade, causing the cutting blade to rotate from bottom to top into the first collection slot on the outer wall of the positioning column, cutting the annular waste in the annular slot into strips, making it convenient for the operator to collect the waste and process it subsequently. The top of the cutting blade is U-shaped to prevent the annular waste from slipping off when the cutting blade rotates and cutting, which would cause incomplete cutting and mixing with the cut waste, affecting the operator's collection.

[0025] like Figures 1 to 4As shown, an embodiment of this utility model provides a plastic product edge trimming machine, including a cutting table 1, a motor 2 fixedly connected to the bottom of the cutting table 1, a first connecting block 3 fixedly connected to the output end of the motor 2, and a second connecting block 4 fixedly connected to the top of the first connecting block 3; a positioning component, which is used to assist the operator in completing the product cutting operation. The positioning component is connected to the cutting table 1 and the second connecting block 4 respectively. The motor 2 is fixed to the bottom center of the cutting table 1 by bolts. The working principle of the motor 2 is disclosed in the prior art. The first connecting block 3 is a disc-shaped object fixed through a threaded hole at the bottom. The second connecting block 4 is a cylinder larger than the first connecting block 3 and fixed by bolts. During the cutting operation, the motor 2 can drive the first connecting block 3, the second connecting block 4, the positioning column 5, and the product on the positioning column 5 to rotate. The plastic edge trimming machine provided by this application can not only assist the operator in completing the cutting operation of irregular edges and burrs on the product, but also push the cut product and the annular waste generated by cutting upwards, and cut the annular waste into strips during the upward pushing process, which is convenient for the operator to collect and process in a concentrated manner afterward, thereby improving the product cutting and production efficiency.

[0026] As one implementation method in this embodiment, such as Figures 1 to 4 As shown, the positioning assembly includes a positioning post 5 fixedly connected to the top of the second connecting block 4. The top of the cutting table 1 is fixedly connected to a first cylinder 9, a fixing frame 10, and a mounting base 11. A cutting blade 6 is rotatably connected to the inner side wall of the positioning post 5 near its bottom end. A waste collection tray 14 is screwed to the output end of the first cylinder 9. The main body of the positioning post 5 is cylindrical, and there is a cylindrical fixing base at the bottom. The positioning post 5 is fixed by bolts. The fixing principle and working principle of the first cylinder 9, the fixing frame 10, and the mounting base 11 are all disclosed in the prior art. The waste collection tray 14 is disc-shaped, with a circular hole in the middle that matches the outline of the main body of the positioning post 5. It is fixed by screwing through the threaded hole at the bottom. The waste collection tray 14 is located on the outer wall of the positioning post 5. The top of the waste collection tray 14 has an annular groove for accommodating annular waste. The first cylinder 9 pushes the waste collection tray 14 to move upward along the outer wall of the positioning post 5, pushing the bottom of the product upward together. The annular waste generated by the product cutting will fall into the annular groove for collection. The above-mentioned structural setting can facilitate and quickly pick up the product and waste.

[0027] In this embodiment, as Figures 1 to 4As shown, a second cylinder 12 is fixedly connected to the top of the mounting base 11. A cutting blade 13 is screwed onto the outer wall of the output end of the second cylinder 12. A third cylinder 16 is fixedly connected to the top of the fixing bracket 10. A third connecting block 17 is fixedly connected to the output end of the third cylinder 16. A circular pressure block 18 is fixedly connected to the bottom of the third connecting block 17. The third connecting block 17 is a cylinder and is fixed by bolts. The second cylinder 12 is fixed by bolts, the cutting blade 13 is fixed by threads, the third cylinder 16 is fixed by bolts, and the circular pressure block 18 is fixed by bolts. The circular pressure block 18 consists of a smaller disc and a larger disc. The cylinder is composed of a disc that is fixed to the surface of the cylinder by bolts. The working principles of the second cylinder 12, the cutting blade 13 and the third cylinder 16 are all disclosed in the prior art. The second cylinder 12 pushes the cutting blade 13 to slowly approach the product for cutting. The third cylinder 16 pushes the third connecting block 17 and the circular pressing block 18 to press the top of the product, and firmly fixes the product on the positioning post 5. The above-mentioned structural setting can prevent the product from sliding up and down on the surface of the positioning post 5 during product cutting, which would prevent the cutting blade 13 from accurately cutting off the irregular edges and burrs of the product or from cutting and damaging the product, thus affecting the production efficiency of the product.

[0028] In this embodiment, as Figures 5 to 8 As shown, the outer wall near the bottom of the positioning post 5 and the top of the waste collection tray 14 are respectively provided with a first storage groove 7 and a second storage groove 15 that match the contour of the cutting blade 6. A limiting groove 8 is provided on one side of the cutting blade 6, and the top of the cutting blade 6 is "U"-shaped. A limiting rod is fixedly connected to the inner side wall of the second storage groove 15. The limiting rod slides along the limiting groove 8. The above structure allows the limiting rod to slide inside the limiting groove 8 of the cutting blade 6 when the first cylinder 9 pushes the waste collection tray 14 to move upward with the product and the annular waste. The cutting blade 6 rotates from bottom to top into the first storage groove 7 on the outer wall of the positioning post 5 to cut the annular waste in the annular groove into strips. The "U"-shaped top of the cutting blade 6 can prevent the annular waste from slipping off during the cutting rotation, resulting in incomplete cutting and mixing with the cut waste, which is convenient for the operator to collect and speed up the cleaning rate.

[0029] The working principle of the technical solution provided by this utility model is as follows: In use, place the product to be cut with the opening facing down onto the positioning post 5. Then, the third cylinder 16 pushes the circular pressing block 18 to press down on the top of the product, fixing the product onto the positioning post 5. This prevents the product from sliding up and down on the outer wall of the positioning post 5 during the cutting operation, which would affect the cutting effect. Start the motor 2 and the second cylinder 12. The motor 2 drives the positioning post 5 and the product to rotate. The second cylinder 12 pushes the cutting blade 13 to slowly approach the product to cut the irregular edges and burrs. The irregular edges and burrs are cut off and fall into the annular groove of the waste collection tray 14. When the product is picked up after cutting, the third cylinder 16 and the second cylinder 12 respectively drive the circular pressing block 18 to press down on the top of the product, fixing the product onto the positioning post 5. The forming block 18 and the cutting blade 13 retract, leaving a gap for easy product retrieval. The first cylinder 9 pushes the waste collection tray 14 to slide on the outer wall of the positioning post 5. The top of the waste collection tray 14 contacts the product and pushes it upward. During the sliding process, the limiting rod on the inner side wall of the second storage groove 15 slides in the limiting groove 8, and rotates the cutting blade 6 from bottom to top into the first storage groove 7 on the outer wall of the positioning post 5. At the same time, the annular waste in the annular groove is cut into strips, which makes it convenient for the operator to collect and speeds up the cleaning process. After the product is pushed up to a certain height for easy retrieval, the first cylinder 9 is closed, and the product and strip-shaped waste are taken out together.
