Description

Technical Field

[0001] This utility model relates to the field of cutting machine technology, and in particular to a cutting machine with an intermittent feeding structure. Background Technology

[0002] A cutting machine is a device used to cut various flexible materials to a predetermined shape or size. It is commonly used for cutting non-metallic materials such as leather, rubber, plastics, fabrics, paper, and foam. Its main working principle is to use pressure to press a die (or mold) mounted on the machine into the material, thereby achieving fast and precise cutting. Depending on the structure and drive method, cutting machines can be divided into various types, including mechanical, hydraulic, and fully automatic cutting machines, and are widely used in industries such as footwear, clothing, packaging, and automotive interiors. Cutting machines are characterized by easy operation, high efficiency, good precision, and wide material adaptability, and can significantly improve the automation level and product consistency of industrial production.

[0003] In the processing of foam sponges, existing technologies typically employ cutting machines for quantitative cutting. However, most current cutting machines have certain limitations. This is because the conveyor belts used to transport the foam sponges lack an intermittent feeding structure, resulting in the foam sponges not being effectively interrupted during the cutting process. This continuous feeding method makes the foam sponges prone to slippage, shaking, or uneven tension during cutting, leading to cut deviations and affecting cutting quality. Furthermore, continuous feeding causes excessive wear on the cutting blades, increasing equipment maintenance costs and the frequency of blade replacement. These problems restrict the improvement of production efficiency and make it difficult to meet the demands of modern industry for automated, high-efficiency, and high-precision production.

[0004] Therefore, there is an urgent need for a cutting machine with an intermittent feeding structure to solve the above problems, improve the accuracy and efficiency of foam cutting, reduce equipment maintenance costs, and better meet the high standards of modern industrial production. Based on this, we propose a cutting machine with an intermittent feeding structure. Utility Model Content

[0005] The purpose of this section is to outline some aspects of the embodiments of this utility model and to briefly introduce some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this utility model, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be used to limit the scope of this utility model.

[0006] Therefore, the purpose of this utility model is to provide a cutting machine with an intermittent feeding structure, which can solve the problems of slippage, shaking, uneven tension, cutting deviation and excessive wear of cutting tools caused by the lack of an intermittent feeding structure in the conveyor belt during the cutting process of foam sponge.

[0007] To solve the above technical problems, this utility model provides a cutting machine with an intermittent feeding structure, which adopts the following technical solution: it includes a material conveyor belt, a cutting component is installed on the top of the material conveyor belt, a transmission component is also provided on one side of one end of the material conveyor belt, the cutting component includes two sets of support frame plates, a cutting component is connected between the middle of the two sets of support frame plates, and an elliptical rotating plate is connected between the tops of the two sets of support frame plates through a bearing; One side of one of the support frames is provided with a first auxiliary frame, and the interior of the first auxiliary frame is also connected to a first pulley through a bearing. The first pulley is connected to the elliptical rotating plate by a transmission connection. The transmission assembly includes a connecting base plate, a motor transmission box is mounted on the top of the connecting base plate, an incomplete gear is connected to one side of the motor transmission box, a second auxiliary frame is provided on one side of the motor transmission box, and a second pulley is also connected to the second auxiliary frame and the motor transmission box. The inner sides of both sets of support plates are provided with guide grooves, and guide blocks are slidably connected inside the guide grooves of both sets. Two sets of compression springs are connected between the guide blocks and the guide grooves. The guide block has a positioning slot in the middle and positioning holes on both sides of the top.

[0008] Optionally, the cutting component includes a triangular transmission plate, which matches the elliptical rotating plate structure and is in rolling contact with the elliptical rotating plate. A cutting blade is connected to the bottom of the triangular transmission plate, and the cutting blade matches the positioning slot structure. Two sets of positioning pins are also provided on both sides of the triangular transmission plate near the cutting blade, and the positioning pins are engaged with the positioning holes.

[0009] Optionally, a transmission gear is connected to one end of the material conveyor belt, and the transmission gear is matched with an incomplete gear structure, and the transmission gear and the incomplete gear are meshed together.

[0010] In summary, this utility model has at least one of the following beneficial effects: 1. The cutting machine designed in this scheme uses the ingenious combination of incomplete gears and transmission gears. When the motor transmission box drives the incomplete gears to rotate, the special tooth distribution of the incomplete gears allows the transmission gears to intermittently obtain power and drive the material conveyor belt to rotate. This enables precise intermittent conveying of foam sponge boards, achieving stable feeding of materials during the cutting process. It avoids problems such as slippage, shaking, or uneven tension caused by continuous feeding, thereby greatly improving the cutting quality, ensuring the accuracy and neatness of the cut, and meeting the high-precision cutting requirements of modern industrial production.

[0011] 2. The cutting machine designed in this scheme, through the coordinated action of various components in the cutting assembly, drives the elliptical rotating plate to rotate when the motor transmission box is running, with the help of the first pulley, the second pulley and the transmission belt. Then, by utilizing the rolling contact between the triangular transmission plate and the elliptical rotating plate, the triangular transmission plate can be pressed downward, so that the cutting blade punches and cuts the foam sponge board. Through the cooperation of the guide block and the compression spring, the cutting blade can be quickly reset, which can prepare for the next cutting. This structural design not only improves the cutting efficiency, but also effectively reduces the ineffective friction between the blade and the material, reduces the blade wear rate, and achieves the effect of extending the service life of the cutting blade, reducing equipment maintenance costs and replacement frequency.

The first pulley 8 is connected to the elliptical rotating plate. The connection between 6 is a transmission connection. The cutting machine uses the cooperation between the incomplete gear 11 and the transmission gear 22 to control the intermittent feeding of the material conveyor belt 1 with foam sponge board placed on top. Through the cooperation between the guide groove 14, the positioning slot 17 and the triangular transmission plate 19, the motor transmission box 10 can control the intermittent transmission of the material conveyor belt 1, and at the same time control the downward pressure of the triangular transmission plate 19 with the cutting blade 20 installed at the bottom. The downward-pressed cutting blade 20 can perform stamping and cutting of the foam sponge board on top of the intermittently conveyed material conveyor belt 1.

[0017] The transmission assembly 3 includes a connecting base plate 9, a motor transmission box 10 mounted on the top of the connecting base plate 9, an incomplete gear 11 connected to one side of the motor transmission box 10, a second auxiliary frame 12 provided on one side of the motor transmission box 10, and a second pulley 13 connected between the second auxiliary frame 12 and the motor transmission box 10. The motor transmission box 10, through the incomplete gear 11 and the second pulley 13 connected to both sides, is used for intermittent transmission of the material conveyor belt 1, and can also perform stamping transmission of the cutting blade 20. Guide grooves 14 are provided on the inner sides of both sets of support plates 4, and guide blocks 15 are slidably connected inside both sets of guide grooves 14. Two sets of compression blocks 15 are connected between the guide blocks 15 and the guide grooves 14. The spring 16, through the guide block 15 and compression spring 16 set inside the guide groove 14, can support the triangular transmission plate 19 with the cutting blade 20 mounted on the bottom between the two sets of support plates 4, and can also elastically push the downward-pressed triangular transmission plate 19 upward, so as to realize the reset of the cutting blade 20. The guide block 15 has a positioning slot 17 in the middle, and positioning holes 18 are respectively opened on the top two sides of the guide block 15. Through the positioning slot 17 and positioning holes 18 opened on the guide block 15, the triangular transmission plate 19 can be supported between the two sets of support plates 4, and can also support the two sides of the cutting blade 20 mounted on the bottom of the triangular transmission plate 19.

[0018] The cutting component 5 includes a triangular transmission plate 19, which is structurally matched with the elliptical rotating plate 6. The triangular transmission plate 19 and the elliptical rotating plate 6 are in rolling contact. A cutting blade 20 is connected to the bottom of the triangular transmission plate 19, and the cutting blade 20 is structurally matched with the positioning slot 17. Two sets of positioning pins 21 are respectively provided on both sides of the triangular transmission plate 19 near the cutting blade 20. The positioning pins 21 and the positioning holes 18 are in a snap-fit ​​fit. Through the rolling contact structure between the triangular transmission plate 19 and the elliptical rotating plate 6, when the elliptical rotating plate 6 rotates, it can press down on the triangular transmission plate 19 with the cutting blade 20 attached to its bottom. The downwardly pressed cutting blade 20 can perform stamping and cutting processing on the foam sponge board placed on top of the material conveyor belt 1. One end of the material conveyor belt 1 is connected to a transmission... The drive gear 22 and the transmission gear 22 are structurally matched with the incomplete gear 11. The transmission gear 22 and the incomplete gear 11 are meshed together. The transmission gear 22 is connected to one side of the material conveyor belt 1, and the transmission gear 22 and the incomplete gear 11 are meshed together. When the transmission gear 22 can mesh with the incomplete gear 11 which has toothed surfaces, the incomplete gear 11 can drive the material conveyor belt 1 with foam sponge boards on top to rotate through the transmission gear 22. The rotating material conveyor belt 1 can transport the foam sponge boards on top. When the meshing contact surface between the incomplete gear 11 and the transmission gear 22 switches to the side without teeth, it cannot mesh with the transmission gear 22. At this time, the material conveyor belt 1 with foam sponge boards on top stops transporting.

[0019] Working Principle: The cutting machine designed in this scheme mainly consists of a material conveyor belt 1, a cutting assembly 2, and a transmission assembly 3. The transmission assembly 3 includes a connecting base plate 9, a motor transmission box 10, an incomplete gear 11, a second auxiliary frame 12, and a second pulley 13. This transmission assembly 3 works through the cooperation between the incomplete gear 11 and the transmission gear 22. When the energized motor transmission box 10 drives the incomplete gear 11 to rotate, because the transmission gear 22 and the incomplete gear 11 are structurally matched and meshed, the transmission gear 22 can mesh with the incomplete gear 11, which has toothed surfaces. When the incomplete gear 11 is engaged, it can drive the transmission gear 22 to rotate. Since the transmission gear 22 is connected to the material conveyor belt 1, it can drive the material conveyor belt 1 with foam sponge boards on top to rotate. The rotating material conveyor belt 1 can transport the foam sponge boards on top. When the meshing contact surface between the incomplete gear 11 and the transmission gear 22 switches to the side with missing teeth, it cannot mesh with the transmission gear 22. At this time, the material conveyor belt 1 with foam sponge boards on top stops transporting. As can be seen from the above, the material conveyor belt 1 with this structure can achieve the effect of intermittent feeding of foam sponge boards.

[0020] The cutting machine designed in this scheme uses a cutting component 2 installed on the material conveyor belt 1. The cutting component 2 consists of a support frame plate 4, a cutting part 5, an elliptical rotating plate 6, and other components. The cutting part 5 works in conjunction with the guide groove 14, the positioning slot 17, and the triangular transmission plate 19. When the motor transmission box 10 is powered on, it can intermittently control the transmission of the material conveyor belt 1. At the same time, it can also drive the elliptical rotating plate 6 to rotate through the cooperation of the first pulley 8, the second pulley 13, and the transmission belt. When the elliptical rotating plate 6 rotates, the triangular transmission plate 19 and the elliptical rotating plate 6 are in rolling contact. The triangular transmission plate 19, which has a cutting blade 20 installed at the bottom, can be pressed downward. The downwardly pressed cutting blade 20 can punch and cut the foam sponge board placed on top of the material conveyor belt 1. The cutting blade 20, through the cooperation of the guide block 15 and the compression spring 16, can also elastically push the downwardly pressing triangular transmission plate 19 upward, so as to realize the reset of the cutting blade 20.
