[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] The present invention provides two technical solutions:

[0026] Figures 1-4 The first implementation manner is shown: a trimming mechanism for plastic cup production, including a workbench 1 and a plastic cup body 4. A trimming mechanism 2 is provided on the top of the workbench 1 for trimming the plastic cup. The trimming mechanism 2 includes:

[0027] A rotating assembly 21, the rotating assembly 21 includes a mounting frame 213, a roller 214 is rotatably provided on the inner wall of the mounting frame 213, and a rubber pad 215 is sleeved outside the roller 214;

[0028] A moving assembly 22, the moving assembly 22 includes a base 221, and a cup holder 225 is provided on the top of the base 221;

[0029] Two grinding assemblies 23 are provided.

[0030] Chute 11 is symmetrically opened on the top of the workbench 1. Legs 12 are fixedly installed at positions near the four corners of the bottom of the workbench 1. The rotating assembly 21 further includes a motor 211 fixedly installed at the bottom of the workbench 1. The output end of the motor 211 movably penetrates the bottom of the workbench 1 and extends upward. A rotating shaft 216 is fixedly installed at the output end of the motor 211. A driving gear 217 is fixedly sleeved on the outer wall of the rotating shaft 216. The end of the rotating shaft 216 movably penetrates the bottom of the mounting frame 213 and extends to the other side and is fixedly connected to the end of the roller 214. A support plate 212 is fixedly installed at the bottom of the mounting frame 213. The support plate 212 is fixedly installed at a position near the rear side of the top of the workbench 1. An idler gear 218 is meshed with the outer surface of the driving gear 217. By providing the idler gear 218, it is convenient for the turning of the cup holder 225 to be consistent with the turning of the rubber pad 215. The bottom end of the idler gear 218 is fixedly connected to a connecting shaft 219, and the connecting shaft 219 is rotatably provided on the top of the workbench 1.

[0031] The driving motor 211 is started to drive the rotating shaft 216 to rotate. When the rotating shaft 216 rotates, on the one hand, the rubber pad 215 on the drum 214 rotates, and on the other hand, under the interaction of the driving gear 217, the idler gear 218 and the driven gear 224, the cup holder 225 rotates, and the rotation direction of the cup holder 225 is the same as that of the rubber pad 215. When the cup holder 225 rotates, the plastic cup body 4 rotates. At the same time, the rubber pad 215 contacts the cup mouths of all the plastic cup bodies 4 and has a certain frictional resistance, thereby assisting the plastic cup body 4 to rotate synchronously with the cup holder 225, avoiding the smooth surface of the plastic cup body 4 and the slipping phenomenon between different layers, and improving the trimming efficiency.

[0032] Figures 1-4 The second embodiment is shown. The main difference from the first embodiment is that the moving component 22 further includes an electric push rod 227 fixedly installed near the middle position at the top of the workbench 1. The telescopic end of the electric push rod 227 is fixedly connected to the position near the front side at the bottom of the base 221. A round hole 222 is formed through the top of the base 221. A rotating shaft 223 is rotatably arranged inside the round hole 222. The bottom end of the rotating shaft 223 is fixedly connected with a driven gear 224. The driven gear 224 cooperates with the idler gear 218. The top end of the rotating shaft 223 is fixedly connected with a cup holder 225. T-shaped blocks 226 are symmetrically and fixedly connected to the bottom of the base 221. The T-shaped blocks 226 are slidably arranged inside the sliding grooves 11. Through the cooperation of the T-shaped blocks 226 and the sliding grooves 11, the guiding and limiting effects on the base 221 during the moving process are achieved. Rack bars 228 are fixedly connected to both the left and right sides of the base 221. The plastic cup body 4 is sleeved on the outer surface of the cup holder 225. The two trimming components 23 include rotating columns 231 symmetrically rotatably arranged at the top of the workbench 1. A large gear 232 is fixedly sleeved on the outer wall of the rotating column 231. The large gear 232 is meshed with the rack bar 228. By pushing the base 221 forward through the electric push rod 227, at the same time, the grinding rods 234 on both sides also expand outward, so as to facilitate the personnel to take. A connecting plate 233 is fixedly connected to the end of the rotating column 231. A grinding rod 234 is arranged on the top of the connecting plate 233. The surface of the grinding rod 234 has a certain roughness, which is convenient for trimming the plastic cup body 4. Brackets 3 are symmetrically and fixedly installed at the position near the rear side at the top of the workbench 1. Slots 31 are formed at the top of the brackets 3. A brush plate 32 is inserted inside the slots 31. One side of the brush plate 32 is composed of soft bristles. During the trimming process, the brush plates 32 on both sides also contact the cup mouths, so as to clean the debris generated during trimming, and through the cooperation of the slots 31 and the brush plate 32, it is convenient to replace the brush plate 32 later.

[0033] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0034] During use, stack the plastic cup bodies 4 to be trimmed and deburred together and place them on the cup holder 225. Control the electric push rod 227 to contract, pull the base 221 backward until the cup mouth of the plastic cup body 4 contacts the rubber pad 215. At the same time, the driven gear 224 meshes with the idler gear 218. And when the base 221 moves, through the meshing of the large gears 232 on both sides of the base 221 and the rack 228, the two large gears 232 rotate inward, so that the two grinding rods 234 move closer to the inside. When the cup mouth of the plastic cup body 4 contacts the rubber pad 215, the grinding rods 234 will also contact the cup mouth of the plastic cup body 4. Then, start the motor 211 to drive the rotating shaft 216 to rotate. When the rotating shaft 216 rotates, on the one hand, the rubber pad 215 on the roller 214 rotates, and on the other hand, under the interaction of the driving gear 217, the idler gear 218 and the driven gear 224, the cup holder 225 rotates, and the rotation direction of the cup holder 225 is the same as that of the rubber pad 215. When the cup holder 225 rotates, the plastic cup body 4 rotates. At the same time, the rubber pad 215 contacts the cup mouths of all the plastic cup bodies 4 and has a certain frictional resistance, so as to assist the plastic cup body 4 to rotate synchronously with the cup holder 225, avoid the smooth surface of the plastic cup body 4 and the slipping phenomenon between different layers, and improve the trimming efficiency. During the rotation of the plastic cup body 4, the cup mouth continuously rubs against the grinding rods 234, so that the cup mouth of the plastic cup body 4 can be trimmed. During the trimming process, since the brush plates 32 on both sides also contact the cup mouth, the debris generated by the trimming can be cleaned, improving the cleanliness of the plastic cup body 4. After the trimming is completed, push the base 221 forward through the electric push rod 227. At the same time, the two grinding rods 234 on both sides also expand outward, which is convenient for personnel to take, avoiding occlusion or interference during the taking process and improving the blanking efficiency.
