Description

Technical Field

[0001] This utility model relates to the technical field of pearl cotton processing equipment, and in particular to a pearl cotton board slitting machine that prevents sticking. Background Technology

[0002] Pearl cotton (EPE) is a commonly used cushioning and packaging material. In the production process, wide pearl cotton sheets are usually cut into narrow strips or sheets of a specific width.

[0003] However, existing EPE foam board slitting machines have some shortcomings in the slitting process: because EPE foam is relatively soft and has a certain degree of stickiness, the EPE foam board tends to stick to the slitting blades when they are slitting the boards. This not only leads to a decrease in slitting accuracy and dimensional deviations, but also affects slitting efficiency. Operators need to frequently stop the machine to clean the EPE foam residue stuck to the slitting blades. Moreover, the cleaning process is cumbersome, and the residue is not easy to remove completely. Long-term accumulation will also cause wear on the slitting blades, shorten their service life, and increase the maintenance cost of the equipment. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that in the existing EPE foam board slitting machine, the EPE foam board is easy to stick to the slitting parts during the slitting process, which leads to a decrease in slitting accuracy and efficiency, and the sticky EPE foam residue is difficult to clean, affecting the subsequent use of the equipment. Therefore, an anti-sticking EPE foam board slitting machine is proposed.

[0005] To achieve the above objectives, the present invention employs the following technology: an anti-adhesion pearl cotton sheet slitting machine, comprising a frame, a feeding conveyor belt for conveying pearl cotton sheets is provided on the frame, a pressing component is provided on one side of the top of the feeding conveyor belt on the frame, a slitting table is provided at the discharge end of the feeding conveyor belt on the frame, a cutting groove is provided on the slitting table, a cutting mechanism for cutting pearl cotton sheets is provided on the top of the slitting table, and an anti-adhesion mechanism is provided at the discharge end of the feeding conveyor belt on the frame, the anti-adhesion mechanism comprising a heating and blowing component provided on the cutting mechanism, and a chip suction component provided on the frame.

[0006] As a further description of the above technical solution: the cutting mechanism includes a second gantry frame fixed on the slitting table, a cylinder is fixedly installed on the top of the second gantry frame, a blade holder is fixedly connected to the bottom end of the piston rod of the cylinder, a cutting blade is fixedly connected to the bottom of the blade holder, and clamping components are provided on both sides of the blade holder.

[0007] As a further description of the above technical solution: the clamping assembly includes a connecting frame fixed on both sides of the tool holder, a through groove is provided on one side of the connecting frame, a guide rod is provided in the through groove, a spring is sleeved on the guide rod, a sliding block is movably sleeved on the guide rod near the outer wall of the spring, a connecting rod is fixedly connected to the bottom of the sliding block, and a pressure plate is fixedly connected to the bottom of the connecting rod.

[0008] As a further description of the above technical solution: the heating and blowing assembly includes a hot air blower fixedly installed on the second gantry frame. The air inlet of the hot air blower is fixedly connected to a main pipe. Both ends of the main pipe are fixedly connected to flexible hoses. One end of the flexible hose passing through the second gantry frame is fixedly connected to a horizontal pipe fixed on a connecting frame. An inclined blowing nozzle is fixedly connected to the horizontal pipe.

[0009] As a further description of the above technical solution: multiple air blowing nozzles are provided, and the multiple air blowing nozzles are evenly distributed along the length direction of the cutting blade, and the air outlet of the air blowing nozzles faces the cutting blade.

[0010] As a further description of the above technical solution: the dust collection assembly includes a box fixed to the bottom of the cutting table, a pull-out box is provided on the bottom of one side of the box, a suction fan is fixedly installed on the other side of the box, an air inlet pipe is fixedly connected to the air inlet of the suction fan, a filter screen is provided at one end of the air inlet pipe that extends through the box and into the interior, inclined guide plates are fixedly connected to the top of the inner walls on both sides of the box, and the cutting groove is connected to the box.

[0011] As a further description of the above technical solution: the pressing assembly includes a first gantry frame fixed to the top of the frame, and symmetrically opened sliding grooves on both sides of the inner wall of the first gantry frame. An adjusting screw is threadedly connected to the first gantry frame, and a U-shaped frame is rotatably connected to the bottom end of the adjusting screw through a bearing. Sliding blocks that are slidably connected to the sliding grooves are symmetrically fixed to both sides of the U-shaped frame. Several equally spaced pressing rollers are rotatably connected to the inner walls of both sides of the U-shaped frame.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: This invention utilizes a combination of a chip suction component and a heating and blowing component. During the slitting process, the suction fan generates negative pressure, which adsorbs the EPE foam board onto the slitting table through the housing cavity and cutting groove. This not only prevents the EPE foam board from moving during slitting, ensuring slitting accuracy, but also allows the blowing nozzle to deliver hot air to the surface of the cutting blade and the cut surface of the EPE foam board, quickly reducing the stickiness of the board surface and effectively preventing the cut EPE foam boards from sticking together. It also prevents chips from adhering to the cutting blade surface. Combined with the suction effect of the suction fan, chips are directly removed the instant they are generated, solving the fundamental problem of chips "staying" and "falling" in the processing area. Since most chips are sucked away when the cutting blade penetrates the board, there are almost no chips remaining around the cutting blade and in the kerf, improving cutting quality and fundamentally eliminating the "blade sticking" phenomenon caused by chip jamming. This achieves "dust-free" cutting, maintains the cleanliness of the working area, and enhances the practicality of the device. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Reference Figures 1-5 This embodiment provides an anti-adhesion pearl cotton board slitting machine, including a frame 1. The frame 1 is provided with a feeding conveyor belt 2 for conveying pearl cotton boards. A pressing component 3 is provided on one side of the top of the feeding conveyor belt 2 on the frame 1. The pressing component 3 includes a first gantry frame 31 fixed to the top of the frame 1, and symmetrically opened sliding grooves 32 on both sides of the inner wall of the first gantry frame 31. An adjusting screw 33 is threadedly connected to the first gantry frame 31. The bottom end of the adjusting screw 33 is rotatably connected to a U-shaped frame 35 through a bearing. Sliding blocks 34 that are slidably connected to the sliding grooves 32 are symmetrically fixed on both sides of the U-shaped frame 35. A plurality of equally spaced pressing rollers 36 are rotatably connected to the inner walls of both sides of the U-shaped frame 35. A slitting table 5 is provided at the discharge end of the feed conveyor belt 2 on the frame 1. A cutting groove 9 is provided on the slitting table 5. A cutting mechanism 4 for cutting pearl cotton sheets is provided on the top of the slitting table 5. The cutting mechanism 4 includes a second gantry frame 41 fixed on the slitting table 5. A cylinder 42 is fixedly installed on the top of the second gantry frame 41. A knife holder 43 is fixedly connected to the bottom end of the piston rod of the cylinder 42. A cutting blade 44 is fixedly connected to the bottom of the knife holder 43. A clamping assembly is provided on both sides of the knife holder 43. The clamping assembly includes a connecting frame 45 fixed on both sides of the knife holder 43. A through groove 46 is provided on one side of the connecting frame 45. A guide rod 47 is provided in the through groove 46. A spring 48 is sleeved on the guide rod 47. A sliding block 49 is movably sleeved on the guide rod 47 near the outer wall of the spring 48. A connecting rod 410 is fixedly connected to the bottom of the sliding block 49. A pressure plate 411 is fixedly connected to the bottom of the connecting rod 410. The frame 1 is equipped with an anti-sticking mechanism at the discharge end of the feed conveyor belt 2. The anti-sticking mechanism includes a heating and blowing assembly 8 installed on the cutting mechanism 4 and a chip suction assembly 6 installed on the frame 1. Specifically, in use, firstly, the EPE foam sheets to be cut are placed on the feeding conveyor belt 2. The sheets are conveyed by the feeding conveyor belt 2 into the area below the pressing assembly 3. The pressing roller 36 on the U-shaped frame 35 applies force to the upper part of the EPE foam sheets to prevent warping and ensure that the EPE foam sheets are in close contact with the conveyor belt, allowing them to move forward steadily. Moreover, the height of the pressing roller 36 can be adjusted according to the thickness of the EPE foam sheets. To adjust, simply rotate the adjusting screw 33, which will move the U-shaped frame 35 up and down. This causes the lower pressure roller 36 to move up and down, allowing for flexible height adjustment and good applicability. When the pearl cotton sheet is conveyed to the slitting table 5, the suction fan 62 operates, adsorbing the pearl cotton sheet onto the slitting table 5 through the cavity of the housing 61 and the cutting groove 9. Simultaneously, the cylinder 42 is activated, and the piston rod of the cylinder 42 drives the knife holder 43 to move down, thereby driving the cutting blade 44 to move down to slit the pearl cotton sheet. During the descent of the knife holder 43, the connecting frame 45 descends synchronously, synchronously driving the pressure plate 411 to descend, and the pressure plate 411 cuts the pearl cotton sheet. The pearl cotton sheet is pressed together on both sides. The cutting blade 44 first contacts the sheet and continues to move downwards. The sliding block 49 moves upwards along the guide rod 47 to compress the spring 48. During the cutting process, the hot air blower 81 is activated simultaneously. The hot air blower 81 delivers hot air through the hose 83 into the horizontal pipe 84. The hot air is blown onto the cutting blade 44 through multiple evenly distributed blower nozzles 85 to heat the cutting blade 44 and prevent the pearl cotton sheet from sticking to the cutting blade 44. The pearl cotton residue generated during the cutting process falls naturally and passes through the cutting groove. 9 falls into the pull-out box 7 inside the lower housing 61. At the same time, the blower nozzle 85 blows hot air onto the cut surface of the pearl cotton board to reduce the stickiness of the pearl cotton board surface. Combined with the suction force of the suction fan 62, the small amount of debris on the cutting blade 44 and the debris on the pearl cotton board surface are adsorbed and drawn into the pull-out box 7. This effectively prevents the debris from sticking to the cutting blade 44 and the pearl cotton board surface, completing the cutting process of the pearl cotton board. The cut pearl cotton board continues to be conveyed to the next process.

[0017] Furthermore, the heating and blowing assembly 8 includes a hot air blower 81 fixedly installed on the second gantry 41. The air inlet of the hot air blower 81 is fixedly connected to a main pipe 82. Both ends of the main pipe 82 are fixedly connected to hoses 83. One end of the hose 83 passing through the second gantry 41 is fixedly connected to a horizontal pipe 84 fixed on a connecting frame 45. An inclined blowing nozzle 85 is fixedly connected to the horizontal pipe 84. Multiple blowing nozzles 85 are provided. The multiple blowing nozzles 85 are evenly distributed along the length direction of the cutting blade 44, and the air outlet of the blowing nozzles 85 faces the cutting blade 44. The dust collection component 6 includes a housing 61 fixed to the bottom of the cutting table 5. A pull-out box 7 is provided on one side of the bottom of the housing 61, and a suction fan 62 is fixedly installed on the other side of the housing 61. An air inlet pipe 63 is fixedly connected to the air inlet of the suction fan 62. A filter screen 64 is provided at one end of the air inlet pipe 63 that extends through the housing 61 and into the interior. Inclined guide plates 65 are fixedly connected to the top of the inner walls on both sides of the housing 61. The cutting groove 9 is connected to the housing 61.

[0018] Specifically, since the main component of pearl cotton (polyethylene foam) is low-density polyethylene (LDPE), which is a thermoplastic polymer material, it is characterized by easy softening at low temperatures and the intermolecular forces being easily affected by temperature. At room temperature, polyethylene molecules have a stable chain structure with relatively weak van der Waals forces between molecules. However, when the cutting blade 44 comes into contact with the surface of the pearl cotton, the pressure of the cutting blade 44 causes local compression deformation of the polyethylene molecules in the contact area, reducing the distance between molecules and strengthening the van der Waals forces, forming a temporary "viscous adsorption". After the hot air heats the cutting blade 44, the temperature of the cutting blade 44 is transferred to the contact area with the pearl cotton (the temperature is usually controlled at 40-60℃, which is lower than the melting point of polyethylene 110-130℃), preventing the pearl cotton from melting. At this temperature, the contact area of ​​the pearl cotton... The increased thermal motion of polyethylene molecules weakens the van der Waals forces between molecules, disrupting the previously tightly packed molecular arrangement formed by compression. This increases the distance between molecules and significantly reduces the adsorption capacity. The heated pearl cotton contact layer becomes softer and less likely to form a strong adsorption with the blade surface. Pearl cotton debris (polyethylene microparticles) generated during the slitting process easily adheres to the surface of the cutting blade 44 at room temperature and is difficult to remove due to intermolecular forces. When hot air continues to blow onto the cutting blade 44, on the one hand, the airflow of the hot air will directly blow away some of the loose debris; on the other hand, the increased surface temperature of the heated cutting blade 44 causes the attached polyethylene debris to soften slightly. The softened debris molecules have reduced adsorption force on the surface of the cutting blade 44 and are more easily carried away by the airflow, avoiding "secondary adhesion" caused by debris accumulation. Two sets of air nozzles 85 are configured, one on each side of the cutting blade 44. The spray direction of the air nozzles 85 forms a 45° angle with the cutting direction of the cutting blade 44. This configuration ensures that hot air is evenly blown onto the cut surface of the pearl cotton board, quickly reducing its stickiness and preventing adhesion. Simultaneously with the cutting blade 44 cutting the pearl cotton board, the hot air blower 81 is activated. The hot air is delivered through the hose 83 into the horizontal pipe 84, and then blown onto the cutting blade 44 by multiple evenly distributed air nozzles 85, uniformly heating both sides of the cutting blade 44 and preventing the pearl cotton board from sticking to the cutting blade 44. During the cutting process, the residual pearl cotton material naturally falls through the cutting groove 9 into the pull-out box 7 inside the lower housing 61. Simultaneously, the blower nozzle 85 blows hot air onto the cut surface of the pearl cotton sheet to reduce its stickiness. At the same time, the suction fan 62 is activated to adsorb the small amount of debris adhering to the surface of the cutting blade 44, causing the debris to fall into the pull-out box 7 through the guide plate 65. This facilitates the collection and processing of debris, effectively preventing it from sticking to the cutting blade 44 and the pearl cotton sheet surface, ensuring the quality of the cut. The pull-out design of the pull-out box 7 facilitates subsequent processing of debris and makes it convenient to use.
