Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sealing cover processing equipment, in particular to a surplus material trimming mechanism for finished sealing covers. Background Art
[0002] Plastic caps are a common packaging form for bottles, cans, and barrels. Sealing caps are generally made of polyolefin as the main raw material and are formed through processes such as injection molding and hot pressing. The corners of plastic parts formed by injection molding or hot pressing usually have excess material. Most sealing caps are round. Plastic products often produce burrs during the production process. There are many reasons, such as molding process, mold design, and raw material quality. These burrs are not only rough, but also have sharp edges, which can easily scratch the human body or other objects. At the same time, they will also affect the appearance and shape of plastic parts, giving consumers a bad visual experience. Because the excess material of thermoplastic forming is usually irregular in shape, it needs to be manually cut with a blade, and the circular seal needs to be cut along the edge. Manual cutting requires certain skills. For workers who are not proficient in the skills, it is easy to cause damage to the sealing cap, and the cutting efficiency is relatively low.
[0003] In view of this, we propose a mechanism for trimming the residual material of the finished sealing cover, which can reduce the difficulty of cutting the residual material of the sealing cover and quickly cut the residual material of the sealing cover of different sizes. Utility Model Content

DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] See also Figure 1 - Figure 4 , the utility model provides a technical solution:
[0025] A mechanism for trimming the excess material of a finished sealing cover, comprising a main disc 1 and a fixed bracket 2, wherein the fixed bracket 2 is installed inside the main disc 1, wherein the main disc 1 comprises a disc body 11 and a main shaft 14, wherein the main shaft 14 is installed at the center of the disc body 11, wherein a cutter 3 is rotatably connected to the surface of the main shaft 14, wherein the surface of the disc body 11 is surrounded by a plurality of slideways 12, wherein the interiors of the plurality of slideways 12 are respectively provided with control rods 13, wherein the surface of the control rod 13 is connected to a connecting rod 23, wherein the connecting rod 23 is connected to the A telescopic rod 22 is installed inside the sleeve rod 21. There are two sleeve rods 21 in total. The two sleeve rods 21 are crossed inside the disc. There are four telescopic rods 22 in total. The four telescopic rods 22 are respectively arranged inside the sleeve rod 21. Through the coordinated use of the fixed bracket 2 and the cutter 3, the fixed bracket 2 can be installed inside the sealing cover, so that the cutter 3 surrounds and cuts the edge of the sealing cover, reducing the difficulty of cutting the plastic sealing cover residue, thereby improving the cutting efficiency of the cutter 3.
[0026] The cutter 3 includes a connecting arm 31 and a telescopic joint 32, wherein the connecting arm 31 is mounted on the surface of the main shaft 14, the end of the connecting arm 31 is connected to the telescopic joint 32, the end of the telescopic joint 32 is mounted on a tool holder 33, two bottom scrapers 34 are arranged on the surface of the tool holder 33, and a side scraper 35 is arranged at the end of the tool holder 33. By using a plurality of scrapers in coordination, the cutter 3 can quickly cut multiple corners of the plastic sealing cover after surrounding the plastic sealing cover, thereby reducing the labor intensity of the operator and improving efficiency.
[0027] An angle of 40° to 70° is set between the bottom scraper 34, and an inclination angle of 30° to 50° is maintained between the bottom scraper 34 and the tool holder 33. The side scraper 35 includes an extension frame and a scraper. The scraper is installed at the top of the extension frame. The extension frame is perpendicular to the tool holder 33. An angle of 120° to 170° is maintained between the tool holder 33 and the scraper. The inclination angle of the scraper ensures that the cutter 3 and the remaining material of the sealing cover are always in an inclination state, so that the cutter 3 can cut normally.
[0028] The main shaft 14 passes through the center of the disk body 11 and the axis of the intersection of the sleeve rod 21. The sleeve rod 21 is fixed by the main shaft 14, and the main shaft 14 is located at the center of the main disk 1 and the fixed bracket 2, so that the cutter 3 can cut along the edge of the circular sealing cover.
[0029] The plurality of slideways 12 are parallel to the sleeve rod 21 of the fixed bracket 2. The slideways 12 are fixed to the surface of the disk body 11 along the direction of the sleeve rod 21, so that the control rod 13 on the slideway 12 can be pulled along the contraction direction of the telescopic rod 22, causing the contraction rod to contract inward.
[0030] A groove is provided between the two side scrapers 35 on the surface of the tool holder 33 to prevent the accumulation of residual materials during the cutting process, which would make the cutter 3 unable to move and affect the scraper on the tool holder 33 from cutting the residual materials.
[0031] When the residual material trimming mechanism of the utility model is used for the finished sealing cover, the fixed bracket 2 needs to be installed inside the sealing cover. The fixed bracket 2 adopts two crossed sleeves, and a telescopic rod 22 is respectively installed at both ends of the two sleeves. When the fixed bracket 2 is placed in front of the sealing cover, it is necessary to grasp the four control rods 13 on the surface of the disk body 11 at the same time, so that the four control rods 13 are retracted along the slide 12, so that the control rods 13 pull the telescopic rods 22 inward through the connecting rods 23, so that the fixed bracket 2 is placed inside the sealing cover, and then the control rods 13 are released. The telescopic rods 22 are extended outward under the drive of the internal spring, so that the top of the telescopic rods 22 contacts the inner wall of the sealing cover, so that the fixed bracket 2 is fixed inside the sealing cover. Since the four sides of the fixed bracket 2 are equal in length, the four sides of the fixed bracket 2 are equal in length. The disk body 11 in the middle of the fixed bracket 2 is fixed at the approximate center of the sealing cover, and then the length of the cutter 3 can be adjusted. Through the telescopic joint 32 at the rear end of the knife holder 33, the bottom scraper 34 and the side scraper 35 on the cutter 3 are fitted to the corners of the disk, and then the cutter 3 can be pushed to make the bottom scraper 34 and the side scraper 35 start cutting. Since the end of the cutter 3 rotates and connects to the main shaft 14 of the center of the disk body 11, the cutter 3 is pushed so that the scraper and the side scraper 35 can surround the corners of the sealing cover, and multiple corners of the sealing cover can be cut simultaneously by circling a circle. After the cutting is completed, the control rod 13 is grasped again to retract the telescopic rod 22, and the trimming mechanism is taken out from the inside of the sealing cover. The method is repeated to continue cutting. Compared with manual cutting with a blade, the operation is simpler, no experience or skills are required, and the cutting efficiency is improved.
