Description

Technical Field

[0001] This utility model belongs to the field of plastic raw material processing technology, and in particular relates to a plastic raw material cutting machine. Background Technology

[0002] In the processing of plastic raw materials, the cutting machine is a key piece of equipment for achieving precise cutting of plastic strips. Traditional cutting machines usually use a single roller conveyor or a simple pressure roller structure, which has problems such as poor conveying stability, strip deviation during cutting, and insufficient adaptability.

[0003] In common plastic granule cutting equipment, plastic strips are prone to slippage during conveying due to insufficient friction, resulting in inconsistent cutting lengths. At the same time, when the plastic strips are cut by the roller cutter, their own elasticity can easily cause them to fly away or deviate, affecting cutting accuracy and posing safety hazards. Furthermore, existing equipment is difficult to flexibly adjust the conveying gap and cannot adapt to the processing needs of plastic strips of different diameters.

[0004] Therefore, there is an urgent need for a cutting machine structure that can achieve stable clamping, precise adjustment, and adaptability to multiple specifications of plastic strips. Utility Model Content

[0005] The purpose of this invention is to provide a plastic raw material cutting machine to solve the problems of slippage and deviation of the material strip during the processing of common plastic granule cutting equipment.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: it includes a cutting machine body and a feeding assembly. The feeding assembly includes a mounting frame, which is connected to the cutting machine body. A conveying roller is provided inside the mounting frame, and a pressure roller is provided above the conveying roller. The mounting frame at both ends of the pressure roller has oblique insertion openings.

[0007] Furthermore, the roller shafts at both ends of the feeding roller are rotatably connected to the mounting frame, and a first gear and a transmission wheel are respectively installed on the outer side of the roller shafts at both ends of the feeding roller. The feeding roller is connected to the motor inside the cutting machine body through a transmission belt set on the outer side of the transmission wheel. Several annular isolation plates are fixedly provided on the feeding roller.

[0008] Furthermore, the pressure roller includes a roller rod with several round protrusions on its surface. A second gear is installed on the outer side of the roller shaft at one end of the roller rod. The first gear meshes with the second gear. A pair of round locking blocks are provided on both ends of the roller rod and are respectively locked on both sides of the mounting frame wall plate.

[0009] Furthermore, the circular protrusion is provided with a groove, and a rubber ring is embedded in the groove. The outer surface of the rubber ring is provided with a plurality of anti-slip protrusions. The circular protrusion is disposed between adjacent isolation plates. A gap is left between the outer surface of the rubber ring and the outer surface of the conveying roller to accommodate the size of the plastic strip.

[0010] Furthermore, the rubber ring belt and the outer surface of the feed roller work together to create a micro-pressure clamping effect on the plastic strip, preventing the plastic strip from flying off due to its own elasticity when it is cut by the roller cutter.

[0011] Furthermore, the roller shaft of the pressure roller is inserted into the oblique insertion opening and clamped to both sides of the mounting frame wall plate by the circular locking block, and the inner thread of the circular locking block engages with the outer thread of the roller shaft of the pressure roller.

[0012] Furthermore, by adjusting the depth of the pressure roller inserted into the oblique opening, the gap size between the outer surface of the rubber ring and the outer surface of the feed roller can be changed to accommodate plastic strips of different diameters.

[0013] Beneficial effects: This utility model is reasonably designed and has the following beneficial effects: 1. In this utility model, the isolation plate of the feeding roller divides the plastic strip into independent channels, and the anti-slip protrusions of the rubber ring increase the friction coefficient and form a micro-pressure flexible clamp with the feeding roller to offset the elastic deformation of the plastic strip during cutting, avoid the risk of flying off, effectively prevent the plastic strip from slipping or deviating during the conveying process, and ensure the consistency of the cutting length. 2. In this utility model, the gap between the pressure roller and the conveying roller can be quickly adjusted through the threaded adjustment mechanism, which is suitable for processing plastic strips with a diameter of 2mm-15mm, significantly improving the versatility of the equipment. The gear transmission system ensures that the conveying roller and the pressure roller rotate synchronously, reducing power loss, and no additional drive components are required, simplifying the equipment structure.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Combination Figures 1 to 4 The plastic raw material cutting machine shown includes a cutting machine body 1 and a feeding component 2. The feeding component 2 includes a mounting frame 21, which is connected to the cutting machine body 1. A feeding roller 22 is provided inside the mounting frame 21, and a pressure roller 23 is provided above the feeding roller 22. The mounting frames 21 at both ends of the pressure roller 23 are provided with oblique insertion openings 211.

[0018] Among them, the roller shafts at both ends of the feeding roller 22 are rotatably connected to the mounting frame 21. The first gear 221 and the transmission wheel 222 are respectively installed on the outer side of the roller shafts at both ends of the feeding roller 22. The feeding roller 22 is connected to the motor inside the cutting machine body 1 through the transmission belt set on the outer side of the transmission wheel 222. Several annular isolation plates 223 are fixedly provided on the feeding roller 22.

[0019] The pressure roller 23 includes a roller rod 231 with several round protrusions 232 on its surface. A second gear 233 is installed on the outside of the roller shaft at one end of the roller rod 231. The first gear 221 meshes with the second gear 233. A pair of round locking blocks 234 are provided on both ends of the roller rod 231 and are respectively locked on both sides of the wall panel of the mounting frame 21.

[0020] The circular protrusion 232 is provided with a groove 235, and a rubber ring belt 236 is embedded in the groove 235. The outer surface of the rubber ring belt 236 is provided with a number of anti-slip protrusions 237. The circular protrusion 232 is arranged between adjacent isolation plates 223. A gap is left between the outer surface of the rubber ring belt 236 and the outer surface of the conveying roller 22 to accommodate the size of the plastic strip.

[0021] The rubber ring belt 236 and the outer surface of the feed roller 22 form a micro-pressure clamping effect on the plastic strip, preventing the plastic strip from flying off due to its own elasticity when it is cut by the roller cutter.

[0022] The roller shaft of the pressure roller 23 is inserted into the oblique insertion opening 211 and clamped to both sides of the mounting frame 21 wall plate by the circular locking block 234. The inner thread of the circular locking block 234 engages with the outer thread of the roller shaft of the pressure roller 23.

[0023] By adjusting the depth of the pressure roller 23 inserted into the oblique insertion opening 211, the gap size between the outer surface of the rubber ring 236 and the outer surface of the feed roller 22 can be changed to accommodate plastic strips of different diameters.

[0024] Working principle: In use, the motor drives the feeding roller 22 to rotate through the transmission, causing the first gear 221 to drive the pressure roller 23 to rotate synchronously, feeding the plastic strip into the inlet of the mounting frame 21. After being separated by the isolation plate 223, the plastic strip is clamped and conveyed by the rubber ring belt 236 of the feeding roller 22 and the pressure roller 23. The anti-slip protrusions 237 of the rubber ring belt 236 press against the surface of the plastic strip, providing stable friction and ensuring that the conveying speed matches the cutting rhythm. According to the diameter of the plastic strip, loosen the circular clamps 234 at both ends of the pressure roller 23, and move the pressure roller 23 down along the inclined insertion opening 211 to reduce the gap between the outer surface of the rubber ring belt 236 and the outer surface of the feeding roller 22 to adapt to the diameter of the plastic strip. Then tighten the circular clamps 234 to fix it. The circular clamps 234 clamp the wall plate of the mounting frame 21 to ensure that the position of the pressure roller 23 is fixed. When the roller cutter of the main body of the cutting machine rotates at high speed to cut the plastic strip, the pressure and clamping of the rubber ring belt 236 keeps the plastic strip fixed at the moment of cutting, avoiding displacement or flying off due to elastic deformation.
