Description

Technical Field

[0001] This utility model relates to the field of pad processing technology, and in particular to a waste shearing device for pad processing. Background Technology

[0002] Pads are auxiliary components made of metal, plastic, etc., used in machining, mold making, and other applications to provide stability, support, and height adjustment. Scrap shearing devices are commonly found on production lines; they cut production waste into smaller, more manageable pieces. Pad processing generates cutting scraps and other waste, which must be processed by scrap shearing devices for recycling and space saving. A search revealed that patent document CN221537807U discloses an inclined waste shearing machine, including a feeding mechanism, a shearing mechanism, a pressing mechanism, and a side pressing mechanism. The feeding mechanism includes a stepped, downwardly inclined conveying push plate and a feeding plate, which are fixedly connected. The driving device is a pushing cylinder, which drives the conveying push plate to reciprocate, thus pushing the waste downwards. The pressing mechanism compresses the waste conveyed to the feeding plate from top to bottom. The side pressing mechanism compresses the waste conveyed to the feeding plate from the outside in. The shearing mechanism shears the waste after it has been compressed by the feeding plate. The discharge mechanism includes a discharge port located below the shearing mechanism, and a downwardly inclined sliding plate is located below the discharge port. This invention is ingeniously designed and suitable for the metal recycling industry and large steel plants, improving waste conveying height and shearing efficiency, ensuring work safety, significantly increasing automation, and saving energy.

[0003] In existing technologies, some equipment exhibits significant waste accumulation issues when shearing off cutting scraps and waste edges generated during mat processing. The cut waste is often difficult to collect systematically, accumulating in large quantities on the cutting table surface. This not only occupies workspace and affects the continuity of subsequent shearing operations, but some waste also spills from the cutting table edges onto the ground, creating a messy environment. This increases the cleaning burden on workers and poses safety hazards such as slips and falls, negatively impacting the overall efficiency and safety of mat processing. Utility Model Content

[0004] The purpose of this invention is to provide a waste shearing device for pad processing, which solves the problem that some waste shearing devices for pad processing accumulate waste on the cutting table and the ground during the cutting process.

[0005] To achieve the above objectives, this utility model provides a waste shearing device for pad processing, including a cutting table, a cutting frame fixedly connected to the top of the cutting table, a cutting mechanism with a limiting cutting mechanism fixedly connected to the front and rear sides of the cutting table, and a waste recycling mechanism fixedly connected to the front side of the cutting frame. The waste recycling mechanism includes a mounting block, the rear of which is fixedly connected to the front of the cutting frame. A motor is fixedly connected to the top of the mounting block, and a bidirectional lead screw is fixedly connected to the drive end of the motor. A guide rod is rotatably connected inside the cutting frame, and two cleaning brushes are rotatably connected to the outside of the bidirectional lead screw. Multiple bristles are fixedly connected to the bottom of the two cleaning brushes, and a gathering block is fixedly connected to the left side of the two cleaning brushes. The guide rod is slidably connected to the inside of the cleaning brushes, and a waste collection assembly is slidably connected to the inside of the cutting table. The restricted cutting mechanism includes two support rods, with adjacent sides of the two support rods fixedly connected to the front and rear sides of the cutting table. A restricting rod is slidably connected inside the two support rods, and a restricting push rod is fixedly connected to the top of the two support rods. The inside of the restricting rod is fixedly connected to the outside of the driving end of the restricting push rod, and an anti-slip pad is fixedly connected to the bottom of the restricting rod. A cutting assembly is fixedly connected to the top of the cutting frame. The waste collection assembly includes two collection boxes, the two collection boxes are slidably connected to the outside of the cutting table, a sliding rod is rotatably connected to the inside of the cutting table, a guide block is fixedly connected to the outside of the sliding rod, a return spring is fixedly connected to the inside of the cutting table, a limiting shaft is fixedly connected to the outside of the sliding rod, and the limiting shaft is slidably connected to the outside of the cutting table. The cutting assembly includes a cutting push rod, the bottom of which is fixedly connected to the top of the cutting frame. Two guide shafts are slidably connected inside the cutting frame. A cutting blade is fixedly connected to the drive end of the cutting push rod, and the top of the cutting blade is fixedly connected to the bottom of the two guide shafts. The two support rods have guide grooves inside, and the limiting rod is slidably connected to the inside of the guide grooves. The limiting rod adopts an I-shaped design. The cutting table has two sliding grooves inside, and the two collecting boxes are slidably connected to the inside of the sliding grooves. The top of the cutting table has a collection port inside, and the guide block is rotatably connected to the inside of the collection port.

The limiting shaft has multiple locking shafts on its left side, and the cutting table has a locking hole on its right side. The locking shafts are slidably connected to the inside of the locking hole. This utility model discloses a waste shearing device for pad processing. The device starts by a motor fixed to the front of the cutting frame by an mounting block, which drives a bidirectional lead screw fixed to the motor drive end to rotate. The threads on the outside of the bidirectional lead screw drive two cleaning brushes. With the assistance of a guide rod, the cleaning brushes reciprocate to clean the sheared waste. A waste collection component slidably connected inside the cutting table can collect the waste cleaned by the cleaning mechanism for subsequent recycling. This utility model discloses a waste material shearing device for processing pads. Two support rods fixed outside the cutting table serve as guides and supports for the limiting rods. When the pad reaches the cutting position, the limiting push rod fixed at the top of the two support rods is activated. The limiting push rod drives the limiting rod fixed at the driving end of the limiting push rod to slide. Then, the pad is restricted by the anti-slip pad at the bottom of the limiting rod, thereby preventing the pad from sliding during the cutting process and affecting the final cutting effect.

[0012] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0013] Please see Figure 1 , Figure 2 and Figure 4 This utility model provides a technical solution: a waste shearing device for processing pads, including a cutting table 1. The cutting table 1 serves as the basic supporting component of the entire waste shearing device, providing a stable installation platform for all functional mechanisms. A cutting frame 2 is fixedly connected to the top of the cutting table 1. The cutting frame 2 is the installation carrier for the cutting component 6 and the waste recycling mechanism 4, and adopts a portal frame structure. A limiting cutting mechanism 3 is fixedly connected to the front and rear sides of the cutting table 1. The limiting cutting mechanism 3 is used to fix the waste before cutting, prevent the waste from shifting during the cutting process, ensure cutting accuracy, and limit the position of the waste to prevent it from popping out during cutting. A waste recycling mechanism 4 is fixedly connected to the front side of the cutting frame 2. The waste recycling mechanism 4 is used to solve the problem of waste accumulating on the cutting table 1. Through the combined design of power drive + brush cleaning + waste gathering, the automatic cleaning and diversion of waste is realized. The waste recycling mechanism 4 includes a mounting block 46, which is a rectangular metal block structure to ensure precise installation of the motor 47 and also serves as a shock absorber to reduce vibration transmission during motor operation. The rear side of the mounting block 46 is fixedly connected to the front side of the cutting frame 2, and the top of the mounting block 46 is fixedly connected to the motor 47. The motor 47 is either a stepper motor or a servo motor, and has forward and reverse rotation functions. The drive end is fixedly connected to a bidirectional lead screw 41 via a coupling, and the speed can be adjusted by the control system to achieve cleaning. The uniform sliding speed of the brush 43 ensures a uniform cleaning effect. The drive end of the motor 47 is fixedly connected to a bidirectional lead screw 41. The bidirectional lead screw 41 has two sections with opposite directions of rotation. When the motor 47 drives the bidirectional lead screw 41 to rotate, the two cleaning brushes 43 can slide in opposite directions along the bidirectional lead screw 41 to clean different areas of the cutting table 1. The cutting frame 2 is rotatably connected to a guide rod 42. The guide rod 42 is a cylindrical optical shaft, which is set parallel to the bidirectional lead screw 41 and passes through the cleaning brushes 43. The guide rod 42 serves as a guide to prevent the cleaning brush 43 from deflecting as the double-ended lead screw 41 rotates, ensuring that it always slides in a straight line. Two cleaning brushes 43 are rotatably connected to the outside of the double-ended lead screw 41. The cleaning brushes 43 ensure that they can slide stably along the double-ended lead screw 41 and the guide rod 42. The bottom is provided with a bristle 44 mounting groove for fixing the bristles 44. Multiple bristles 44 are fixedly connected to the bottom of the two cleaning brushes 43. The bristles 44 ensure that they can fit tightly against the surface of the cutting table 1 during sliding, removing residual waste from the table surface. The material is swept towards the collection port. A gathering block 45 is fixedly connected to the left side of the two cleaning brushes 43. The gathering block 45 has a trapezoidal structure. When the two cleaning brushes 43 slide towards each other, the gathering block 45 can gather the waste material on the edge of the cutting table 1 towards the center of the table surface. It works with the brush bristles 44 to guide the waste material to the collection port and prevent the waste material from falling from the edge of the table surface. The guide rod 42 is slidably connected to the outside of the cleaning brush 43. A waste material collection component 5 is slidably connected to the inside of the cutting table 1. The waste material collection component 5 is used to receive the waste material falling from the collection port. The waste collection assembly 5 includes two collection boxes 51, which facilitate the classification and storage of different types of waste. Each box has a handle on its outer side for easy removal and cleaning by staff. The two collection boxes 51 are slidably connected to the inside of the cutting table 1. A sliding rod 52, a cylindrical metal rod, is rotatably connected inside the cutting table 1 and passes through a mounting groove in the cutting table 1. A fixing ring and a guide block 54 are fixedly connected externally, allowing the rod to slide back and forth along the mounting groove. The fixing ring connects to a return spring 53, ensuring that the tension of the return spring 53 can reset the sliding rod 52. The guide block 54 is fixedly connected externally to the sliding rod 52, guiding the waste into the collection box 51 and preventing it from getting stuck at the collection opening. When the return spring 53 drives the guide block 54 to reset in the gap between the collection boxes 51, the waste stuck in the collection port can be "pushed" into the collection box 51. The return spring 53 is fixedly connected inside the cutting table 1. The rebound force of the return spring 53 can drive the sliding rod 52 to reset backward, thereby driving the guide block 54 to reset. The sliding rod 52 is fixedly connected to the outside of the limiting shaft 55. When it is necessary to fix the collection box 51, push the sliding rod 52 so that the locking shaft on the left side of the limiting shaft 55 is engaged in the locking hole on the right side of the cutting table 1. The sliding rod 52 is fixed through the shaft hole engagement, thereby fixing the position of the guide block 54 and preventing it from shaking randomly during the operation of the device. The limiting shaft 55 is slidably connected to the inside of the cutting table 1. The cutting table 1 has two sliding grooves inside, and the two collection boxes 51 are slidably connected to the inside of the sliding grooves. The top of the cutting table 1 has a collection port inside, and the guide block 54 is rotatably connected to the inside of the collection port. The cutting table 1 has an installation groove inside, and the sliding rod 52 has a fixing ring outside, which is slidably connected to the inside of the installation groove. The other end of the return spring 53 is fixedly connected to the rear side of the fixing ring and the other end of the return spring 53 is fixedly connected to the inside of the installation groove. The left side of the limiting shaft 55 has multiple locking shafts, and the right side of the cutting table 1 has a locking hole. The outside of the locking shaft is slidably connected to the inside of the locking hole. like Figure 1 , Figure 3 , Figure 4As shown, the limiting cutting mechanism 3 includes two support rods 31. The height of the support rods 31 is adapted to the stroke of the cutting assembly 6 to ensure that the limiting rod 33 can completely press the waste material. The adjacent sides of the two support rods 31 are fixedly connected to the front and rear sides of the cutting table 1. The limiting rod 33 is slidably connected inside the two support rods 31. The top of the two support rods 31 is fixedly connected to the limiting push rod 32. When the limiting push rod 32 drives the limiting rod 33 to move downward, the limiting rod 33 can press the waste material on the cutting table 1. The I-shaped structure ensures strength and reduces the contact area with the guide groove, thus reducing sliding resistance. The limiting rod 33 is fixedly connected inside the limiting push rod. On the outside of the drive end of 32, the bottom of the limiting rod 33 is fixedly connected to an anti-slip pad 34. When the limiting rod 33 presses the waste material, the anti-slip pad 34 can increase the friction between the limiting rod and the waste material to prevent the waste material from sliding during the cutting process. At the same time, the rubber material has a certain elasticity, which can avoid damaging the surface of the waste material. The top of the cutting frame 2 is fixedly connected to a cutting component 6. The cutting component 6 is the core actuator for cutting the waste material. Through the combination design of guide + drive + cutting, the accuracy and stability of the waste material cutting are ensured. The two support rods 31 have guide grooves inside, and the outside of the limiting rod 33 is slidably connected to the inside of the guide groove. The limiting rod 33 adopts an I-shaped design. The cutting assembly 6 includes a cutting push rod 62. The extension and retraction speed and thrust of the driving end of the cutting push rod 62 can be adjusted by a hydraulic system. Different cutting parameters can be adapted according to the material and thickness of the waste to ensure that the waste can be cut quickly and flat. The bottom of the cutting push rod 62 is fixedly connected to the top of the cutting frame 2. Two guide shafts 61 are slidably connected inside the cutting frame 2. The function of the guide shafts 61 is to limit the movement trajectory of the cutting blade 63, ensuring that the cutting blade 63 can only move vertically up and down, avoiding its deviation during the cutting process, thereby ensuring the flatness of the cut. The driving end of the cutting push rod 62 is fixedly connected to the cutting blade 63. The cutting blade 63 ensures that the waste in the width direction of the table can be covered in one go, achieving efficient cutting. At the same time, the blade can be designed as a detachable structure for easy replacement after wear. The top of the cutting blade 63 is fixedly connected to the bottom of the two guide shafts 61.

[0014] Working principle: The pad to be cut is pushed from the left side of the top of the cutting table 1 to the cutting assembly 6. After the pad reaches the position, the limiting push rod 32 fixed on the top of the two support rods 31 is activated. The limiting push rod 32 drives the limiting rod 33 fixed on the driving end of the limiting push rod 32 to slide. Then, the pad is restricted by the anti-slip pad 34 at the bottom of the limiting rod 33, thereby preventing the pad from sliding during the cutting process, which would affect the final cutting effect. Then the cutting push rod 62 fixed on the top of the cutting frame 2 is activated, and the cutting blade 63 fixed on the drive end of the cutting push rod 62 is pushed to slide. During the sliding process of the cutting blade 63, the two guide shafts 61 sliding inside the cutting frame 2 guide the cutting blade 63, thereby ensuring the cutting effect of the cutting blade 63. After cutting, the motor 47, which is fixed to the front of the cutting frame 2 by the mounting block 46, is started, which drives the bidirectional lead screw 41 fixed to the drive end of the motor 47 to rotate. The threads on the outside of the bidirectional lead screw 41 drive the two cleaning brushes 43. Then, with the assistance of the guide rod 42, the cleaning brushes 43 reciprocate to clean the cut waste. The waste collection assembly 5, which is slidably connected inside the cutting table 1, can collect the waste cleaned by the cleaning mechanism for subsequent recycling. Once a single collection box 51 is full, the limiting shaft 55 can be pulled, causing the sliding rod 52 to slide. During the pulling process, the limiting shaft 55 disengages from the locking hole inside the collection box 51. Then, the limiting shaft 55 is rotated, causing the sliding rod 52 to rotate, which in turn causes the guide block 54 to rotate in the opposite direction. This allows subsequent waste material to enter the interior of another collection box 51, after which the full collection box 51 can be removed. The limiting shaft 55 is reset with the help of the return spring 53.
