Description

Technical Field

[0001] The invention belongs to the technical field of foam cutting, and in particular relates to a novel upper cutting and lower cutting mechanism for a foam production line. Background Art

[0002] Foam materials are widely used in packaging, construction, automobiles, home appliances and other fields due to their excellent light weight, heat insulation, sound absorption and other properties. However, as the application of foam materials gradually deepens, how to accurately and efficiently cut foam during the production process has become an important challenge in the manufacturing process. There are many types of foam materials, including polystyrene foam, polyurethane foam, foam rubber, etc. The hardness, density, structure and elasticity of each foam vary greatly, which makes the foam cutting process face different difficulties.

[0003] Traditional foam cutting technology usually uses mechanical cutting, thermal cutting or laser cutting. Among them, although mechanical cutting has lower costs, due to the different toughness of the foam, cracks or breaks are prone to occur during the cutting process, and it is difficult to achieve high-precision cutting. Although thermal cutting can cut the foam relatively smoothly, the process is difficult to control, and it is easy to have problems such as uneven cutting surface or excessive surface melting. In addition, the thermal conductivity of foam materials is poor, and it is difficult to evenly distribute the temperature during thermal cutting, which can easily lead to unstable cutting quality. Although laser cutting has higher precision, its equipment cost is high, and the cutting effect on certain types of foam materials is poor, which limits its widespread application.

[0004] On the other hand, foam materials are often unstable when cut due to the softness and elasticity of the material itself. The saw blade in the cutting equipment often deviates due to the rebound and uneven force of the material, resulting in unsatisfactory cutting effect. For example, the saw blade may shake or jump, resulting in an uneven cutting surface or excessive wear of the saw blade. Especially when cutting high-density foam materials, traditional cutting mechanisms are difficult to effectively ensure the stability and tension of the saw blade, which affects the cutting accuracy and increases the maintenance cost of the equipment. Therefore, developing a cutting device that can automatically adjust the cutting state according to the characteristics of different foam materials to ensure a smooth and precise cutting process has become a technical problem that needs to be solved in the industry. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a novel upper cutting and lower cutting mechanism for a foam production line. The specific technical scheme is as follows:

[0006] The present invention provides a novel foam production line upper and lower cutting mechanism, comprising a base frame carrying a roller line for conveying novel foam, a moving frame body arranged transversely across the base frame, guide rails symmetrically arranged below the moving frame, and movable along the longitudinal direction of the base frame, a cutting saw assembly arranged transversely and attached to the moving frame is hung on the moving frame, and a balancing mechanism is symmetrically arranged between the moving frame and the roller line for conveying novel foam;

[0007] The cutting saw assembly comprises a hollow cutting slot in the shape of a Chinese character "concave", wherein rotatable flywheels are respectively rotatably arranged in the cavities on both sides thereof, a saw blade is sleeved between the flywheels, an offset hole is opened in the center thereof, and elastic buckles and motors are respectively inserted into the offset holes of the flywheels on both sides, a locking shaft is extended from the top of the elastic buckle, and a tensioning bolt is passed through the elastic buckle, so that the center distance of the flywheel can be adjusted longitudinally, and the tensioning adjustment of the saw blade is performed;

[0008] The balancing mechanism includes a bar-shaped balancing ruler with a plurality of telescopic grooves formed thereon and respectively embedded with rotatable locking buttons, which can be inserted into the front end of the cutting groove body for fixation; the portion of the balancing ruler extending out of the cutting groove body is clamped with a wrench-shaped stabilizing clamp, and a plurality of rotatable guide wheels clamped in opposite directions are inserted at the bottom thereof to guide the cutting direction of the saw blade, and a limiting wheel is embedded in the upper part of the guide wheel to retract and retract in the opposite direction as the tensioning bolt retracts and limits the shaking of the saw blade.

[0009] As a preferred technical solution of the present invention, the cutting groove body includes a vertically attached concave shell, an end plate is arranged on the left side of the cutting groove, and an elliptical positioning groove is longitudinally arranged at the penetration position of the elastic buckle, which can cooperate with the elastic buckle to position left and right to adapt to different foams.

[0012] The flywheel has an initial state and a tensioning state. In the tensioning state, the flywheel speed increases, and the centrifugal hammer is pressed by the centrifugal force to squeeze the airbag, causing the squeezing airbag to shrink, driving the tensioning airbag to expand, pulling the tensioning bolt back, causing the tension buckle to move to the left, and completing the tensioning of the saw blade. In the initial state, the flywheel speed slows down, and the centrifugal hammer is pressed close to the inner wall by the second return spring, causing the squeezing airbag to expand, driving the tensioning airbag to shrink, and the first return spring pulls the tensioning bolt to feed, causing the tension buckle to move to the right, and completing the relaxation of the saw blade.

[0013] As a preferred technical solution of the present invention, the back of the balance ruler is symmetrically provided with a plurality of linearly arranged hemispherical protrusions, which cooperate with the guide grooves in a concave-convex manner and can be advanced along the grooves as the balance ruler is fed, thereby reducing friction resistance.

[0014] As a preferred technical solution of the present invention, a rotatable driving shaft is embedded in one side of the stabilizing clamp, and rotates synchronously with a limiting wheel connected to the end of the shaft.

[0018] As a preferred technical solution of the present invention, a plurality of rollers vertically connected in parallel are clamped on both sides of the roller line to form straightening wheels, which can be straightened along with the foam feeding of the roller line and used for the direction correction of foam cutting.

[0019] As a preferred technical solution of the present invention, a coaxial ring is mounted on the back of the cutting saw assembly, a cooperative rod is sleeved inside the ring, and the rod end is fixed to the bottom wall of the crossbeam of the moving frame, which can provide anti-slip protection as the lifting frame moves.

[0020] The beneficial effects of the present invention are:

[0021] Improve cutting accuracy and stability: This new cutting mechanism effectively avoids the vibration and deviation of the saw blade during the cutting of foam materials by optimizing the tension device and guide system of the saw blade. By adjusting the flywheel center distance and the control of the tension bolt, the saw blade is always in an ideal tension state, thereby reducing the error caused by insufficient or excessive tension during the cutting process and improving the uniformity and accuracy of the cutting effect.

[0022] Adapt to different foam materials: Due to the wide variety of foam materials, the hardness, density and elasticity of each material vary greatly, and traditional cutting devices often have difficulty adapting to these changes. The new cutting mechanism can be precisely adjusted according to the characteristics of different foam materials by improving the design of the flywheel and the tensioning mechanism. Especially when dealing with foam materials with higher density or more complex structures, the system can automatically adjust the tension of the saw blade to ensure that the cutting effect is not affected by material differences, thus making it more adaptable.

[0023] Reduce the wear and damage of the saw blade during cutting: In traditional foam cutting equipment, the offset and vibration of the saw blade often leads to uneven cutting, and even accelerates the wear and breakage of the saw blade. The new cutting mechanism effectively guides and tensions the saw blade, reduces the damage caused by severe vibration or uneven force on the saw blade, prolongs the service life of the saw blade, and reduces maintenance costs.

[0024] Improve cutting efficiency: By adopting a new cutting mechanism, especially through the cooperation of the balancing mechanism and the guide wheel, the cutting process is more stable and less affected by the surface characteristics of the foam material. In the traditional cutting method, due to the instability of the foam material, it is often necessary to repeatedly adjust the equipment to ensure the cutting effect. The new cutting mechanism can maintain an efficient and stable cutting state during long-term operation, improve production efficiency, and reduce the time for equipment downtime and debugging.

[0025] Improved operational safety: The new cutting mechanism adds a limit wheel and a stabilizing clamp to the tensioning and guiding system of the saw blade, which can effectively prevent the saw blade from shaking, deflecting, breaking and splashing during high-speed cutting, and avoid the risk of splashing between the saw blade and the operator. In addition, the design of the guide wheel can not only guide the cutting direction of the saw blade, but also effectively disperse the impact force on the saw blade, reducing safety hazards during operation.

[0026] Simplified equipment adjustment and maintenance: The cutting device is designed with an easy-to-adjust tensioning mechanism and locking device. Users can easily adjust the tension of the saw blade by rotating the locking knob to meet the cutting requirements of different foam materials. This design makes equipment maintenance and adjustment easier, reduces manual intervention and equipment failures, and improves equipment reliability and service life.

[0027] In summary, this new cutting mechanism not only improves the stability and efficiency of the cutting process through precise tension adjustment, optimization of the balancing system and design of the guide wheel, but also enhances the adaptability to different foam materials, effectively improves the cutting effect, reduces equipment failures and maintenance costs, and has significant technical advantages.

[0057] Please refer to the instruction manual Figure 4-11 The present invention provides a second embodiment of a novel upper and lower cutting mechanism for a foam production line. In this embodiment, the cutting trough body 11 of the upper and lower cutting mechanism is mainly composed of a vertically attached concave shell 111. An end plate 115 is arranged on the left side of the concave shell 111. An elliptical positioning groove 116 is longitudinally arranged on the end plate 115. The positioning groove 116 cooperates with the penetration position of the elastic buckle 13, and the adaptation of different foam sizes can be achieved by moving the elastic buckle 13 left and right. A plurality of fixing holes 112 adapted to the locking button 142 are provided at the front of the concave shell 111. The setting of the fixing holes 112 is used for the fixed installation of the balance ruler 141. The front and rear sides of the fixing holes 112 are horizontally symmetrically arranged with guide grooves 113 with an inverted trapezoidal cross section. The structural design of the guide grooves 113 provides a guiding function for the feeding of the balance ruler 141.

[0058] The back of the balance ruler 141 is symmetrically provided with a plurality of linearly arranged hemispherical protrusions 1412, which form a concave-convex fit with the inner wall of the guide groove 113.

[0060] Embodiment 3

[0061] like Figure 4-10 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0063] The bottom of the offset hole 121 is hinged with a plurality of centrifugal hammers 164, and a centrifugal hinge support 1643 is arranged at the bottom thereof, which can be turned along the center of the circle. A reset hinge support 1642 is arranged on the back of the centrifugal hammer 164, and a second reset spring 165 is connected to the inner wall thereof, which can pull the centrifugal hammer 164 away from the center of the circle to reset.

[0064] The flywheel 12 has an initial state and a tensioned state. In the tensioned state, the speed of the flywheel 12 is accelerated, and the centrifugal hammer 164 is pressed by the centrifugal force to squeeze the airbag 166, causing the squeezing airbag 166 to shrink, driving the tensioning airbag 162 to expand, pulling the tensioning bolt 16 back, causing the tension buckle 13 to move left, and completing the tensioning of the saw blade 5. In the initial state, the speed of the flywheel 12 is slowed down, and the centrifugal hammer 164 is pressed close to the inner wall by the second return spring 165, causing the squeezing airbag 166 to expand, driving the tensioning airbag 162 to shrink, and the first return spring 161 pulls the tensioning bolt 16 forward, causing the tension buckle 13 to move right, and completing the relaxation of the saw blade 5.

[0065] Please refer to the instruction manual Figure 1-7 The present invention provides a first embodiment of a tension adjustment device for tensioning a saw blade 5. In this embodiment, the tension adjustment device is mainly composed of a tension buckle 13, a tension bolt 16, a tension airbag 162, an extrusion airbag 166, a centrifugal hammer 164, a flywheel 12 and other components. A front plate 132 and a rear plate 133 are symmetrically arranged on the top of the tension buckle 13. The front plate 132 and the rear plate 133 are connected by a tension bolt 16. The shaft section of the tension bolt 16 is sleeved with a first return spring 161. One end of the first return spring 161 is fixed to the end plate 115, and the other end is fixed to the front plate 132. It is used to pull the tension bolt 16 to the initial position in a tension state, thereby realizing the relaxation function of the saw blade 5. The axial section of the tensioning bolt 16 also passes through an elastic tensioning airbag 162, and the front end of the tensioning airbag 162 is provided with a tightening port 1621, which is locked and connected to the axial section of the tensioning bolt 16, and the rear end of the tensioning airbag 162 is provided with a fixing port 1622, which is fixed between the rear plates 133, and an elastic hollow bag is sandwiched between the fixing port 1622 and the tightening port 1621 of the tensioning airbag 162, and the hollow bag can expand and contract along the axial section direction of the tensioning bolt 16 to cooperate with the tensioning and relaxing process of the saw blade 5.

[0066] The flywheel 12 is arranged at the center of the device, and an offset hole 121 is arranged circumferentially on its outside. A plurality of centrifugal hammers 164 are arranged at the bottom of the offset hole 121 through a hinge structure. The bottom of the centrifugal hammer 164 is connected to the bottom of the offset hole 121 circumferentially through a centrifugal hinge support 1643, and can be turned around the center of the circle. A reset hinge support 1642 is arranged on the back of the centrifugal hammer 164, and a second reset spring 165 is connected between the reset hinge support 1642 and the inner wall of the offset hole 121, which is used to pull the centrifugal hammer 164 to a reset position away from the center of the circle in the initial state of the flywheel 12. A semicircular hammer surface 1641 is attached to the head of the centrifugal hammer 164, which is used to contact the extrusion airbag 166 in the offset hole 121. The extrusion airbag 166 is located at the center of the offset hole 121 and is designed to be an inverted lotus shape. The top of the extrusion airbag 166 is connected to the tensioning airbag 162 through the hose 163, which can realize the transmission of air pressure to cooperate with the rotation of the flywheel 12 to achieve the tensioning and relaxing functions.

[0067] In the tensioned state of the flywheel 12, the speed of the flywheel 12 is accelerated, and the centrifugal hammer 164 turns outward under the action of centrifugal force, and its semicircular hammer surface 1641 compresses the extrusion airbag 166, causing the extrusion airbag 166 to shrink. The shrinkage of the extrusion airbag 166 is transmitted to the tensioning airbag 162 through the hose 163, causing the tensioning airbag 162 to expand, thereby pulling the tensioning bolt 16 back, driving the tension buckle 13 to move left, and achieving the tensioning of the saw blade 5. On the contrary, in the initial state of the flywheel 12, the speed of the flywheel 12 slows down, and the centrifugal hammer 164 is close to the inner wall of the offset hole 121 under the action of the second return spring 165, and the extrusion airbag 166 expands accordingly. The expansion of the extrusion airbag 166 is transmitted to the tensioning airbag 162 through the hose 163, causing the tensioning airbag 162 to shrink, and the first return spring 161 then pulls the tensioning bolt 16 forward, driving the tension buckle 13 to move right, and achieving the relaxation of the saw blade 5.

[0069] like Figure 1-13 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0070] In this embodiment, a rotatable driving shaft 1432 is embedded in one side of the stabilizing clamp 143, and rotates synchronously with a limiting wheel 1433 connected to the end of the shaft. The surface of the limiting wheel 1433 is coated with a wear-resistant coating, and can synchronously remove the residual materials of foam cutting as the saw blade 5 rotates.

[0071] A plurality of spray pipes 144 extend from both sides of the top of the stabilizing clamp 143 toward the middle, and can spray cutting agents according to the type of cutting foam to reduce the loss of the saw blade 5.

[0072] A claw-shaped bridge 114 is provided in the middle of the concave shell 111 and is hollowed out in the middle to reduce stress concentration when the concave shell 111 cuts the foam.

[0073] The two sides of the roller line 2 are provided with a plurality of rollers connected vertically in parallel to form a straightening wheel 21, which can be straightened along with the foam feeding of the roller line 2 and is used for the direction correction of the foam cutting.

[0074] Please refer to the instruction manual Figure 1-13The present invention provides an embodiment of a foam cutting device. In this embodiment, the foam cutting device is mainly composed of a stabilizing clamp 143, a driving shaft 1432, a limiting wheel 1433, a jet pipe 144, a claw-shaped bridge 114 and a straightening wheel 21. Among them, a rotatable driving shaft 1432 is embedded on one side of the stabilizing clamp 143, and the shaft end of the driving shaft 1432 is connected with the limiting wheel 1433, and the limiting wheel 1433 realizes synchronous rotation through linkage with the driving shaft 1432. The wheel surface of the limiting wheel 1433 is coated with a wear-resistant coating. When the saw blade 5 rotates to cut the foam, the limiting wheel 1433 can rotate synchronously and remove the residual materials generated during the cutting process, so as to keep the cutting area clean and the saw blade 5 stable.

[0075] On both sides of the top of the stabilizing clip 143, multiple spray pipes 144 extending toward the middle are designed, and the spray pipes 144 can be used to spray cutting agent according to the type of foam, thereby reducing the wear of the saw blade 5 and improving the cutting efficiency. The arrangement of the spray pipes 144 ensures that the cutting agent can evenly cover the contact area between the saw blade 5 and the foam, further reducing the resistance during cutting.

[0076] In order to reduce the stress concentration problem of the concave shell 111 foam during the cutting process, a claw-shaped bridge 114 is connected in the middle of the stabilizing clip 143. The claw-shaped bridge 114 is designed as a hollow structure in the middle, which can effectively disperse the stress during the foam cutting process and avoid the foam damage caused by stress concentration. The structural setting of the claw-shaped bridge 114 takes into account the strength of the device and the stability during the foam processing process, ensuring a smooth cutting process.

[0077] In addition, on the foam feeding path, a plurality of rollers are vertically connected in parallel and clamped on both sides of the roller line 2 to form a straightening wheel 21. The straightening wheel 21 calibrates the direction of the foam by synchronous movement with the foam feeding of the roller line 2 to ensure that the foam moves accurately along the predetermined cutting direction. The arrangement of the straightening wheel 21 avoids the deviation phenomenon by adjusting the feeding posture of the foam, so that the saw blade 5 can accurately cut the foam. In summary, the reasonable arrangement of each structure in this embodiment enables the foam cutting device to achieve stable and efficient operation and meet various cutting requirements.

[0079] like Figure 1-14 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0080] In this embodiment, a height adjustment mechanism 7 is symmetrically arranged in the moving frame 4, including a height adjustment motor 71 with its end arranged at the top of the moving frame 4, and a plurality of steering reducers 72 are connected thereto. The steering reducers 72 are interspersed with coaxial shafts 73, which can rotate synchronously with the height adjustment motor 71. The bottom of the steering transmission is respectively connected to a screw module 75, and a lifting frame 74 is vertically attached to its sliding end, and is tightly buckled with the cutting saw assembly 1, and can be moved and positioned with the lifting frame 74.

[0081] A coaxial ring 82 is mounted on the back of the cutting saw assembly 1, and a cooperative rod 81 is sleeved inside the ring. The rod end is fixed to the bottom wall of the crossbeam of the moving frame 4, and can move with the lifting frame 74 to provide anti-falling insurance.

[0082] Please refer to the instruction manual Figure 1-14 The present invention provides a second embodiment of a height adjustment mechanism 7 of a cutting device and a cutting saw assembly 1. In this embodiment, the height adjustment mechanism 7 is symmetrically arranged in the moving frame 4, and the height adjustment mechanism 7 mainly includes a height adjustment motor 71 whose end is arranged at the top of the moving frame 4, and a plurality of steering reducers 72 are connected to the height adjustment motor 71. These steering reducers 72 are connected through a common rotating shaft 73 and can rotate synchronously with the height adjustment motor 71. The bottom of the steering reducer 72 is respectively connected to a screw rod module 75, and the sliding end of the screw rod module 75 is tightly fitted with the lifting frame 74, and is positioned with the cutting saw assembly 1, so that the cutting saw assembly 1 can be adjusted accordingly with the movement of the lifting frame 74.

[0083] Furthermore, a coaxial ring 82 is provided on the back of the cutting saw assembly 1, and a cooperative rod 81 is sleeved in the coaxial ring 82. The other end of the cooperative rod 81 is fixed to the bottom wall of the crossbeam of the moving frame 4, and can effectively provide an anti-falling safety function with the movement of the lifting frame 74. Through this design, the cooperative rod 81 not only stabilizes the overall structure of the cutting saw assembly 1, but also ensures that the cutting saw assembly 1 will not be displaced or fall off during the lifting process.

[0084] The combination of the height adjustment mechanism 7 and the cutting saw assembly 1 in this embodiment realizes the adjustment of the precise position of the cutting saw assembly 1 through the cooperation of the height adjustment motor 71, the steering reducer 72 and the screw module 75. The design of the lifting frame 74 and the cooperative rod 81 further enhances the stability and safety of the equipment, ensuring the efficient operation of the equipment during the cutting operation.

[0085] In summary, this embodiment forms an efficient and stable adjustment and protection system through the close cooperation between the structural design of the height adjustment mechanism 7 and the cutting saw assembly 1, which can achieve precise height adjustment during the cutting process and ensure the safety and stability of the cutting saw assembly 1.

[0086] The working principle and use process of the present invention:

[0087] First, the foam material is placed on the roller line 2 on the base frame 3, and the foam is transported by starting the roller line 2. During the transportation process, the straightening wheels 21 on both sides of the roller line 2 correct the direction of the foam to ensure that the foam maintains a stable posture and direction when entering the cutting area. The moving frame 4 of the cutting mechanism moves longitudinally along the base frame 3 to the starting position of cutting through the bottom guide rail 6. According to the height requirement of the foam, the height adjustment motor 71 on the top of the moving frame 4 is started, and the lifting frame 74 is driven up and down through the steering reducer 72 and the screw module 75, thereby adjusting the height of the cutting saw assembly 1 to match the cutting position of the foam.

[0088] The hollow cutting slot 11 of the cutting saw assembly 1 is provided with flywheels 12 on both sides and a saw blade 5 connected therebetween. The offset hole 121 of the flywheel 12 is provided with a tension buckle 13 and a cutting motor 15. The tension buckle 13 is connected to the tension bolt 16 through a locking shaft 131 extending from the top, and the center distance of the flywheel 12 is changed by adjusting the tension bolt 16, thereby adjusting the tension state of the saw blade 5. Before the start of cutting, the flywheel 12 is in an initial state with a low rotation speed. At this time, the centrifugal hammer 164 in the offset hole 121 is close to the inner wall of the flywheel 12 under the action of the second return spring 165, the squeezing airbag 166 expands, the tensioning airbag 162 shrinks, the first return spring 161 pulls the tension bolt 16 to feed, and pushes the tension buckle 13 to move right, so that the saw blade 5 is in a relaxed state. When cutting begins, the speed of the flywheel 12 gradually increases, and the centrifugal hammer 164 flips outward around the centrifugal hinge support 1643 under the action of centrifugal force. The semicircular hammer surface 1641 compresses the extrusion airbag 166, causing the extrusion airbag 166 to shrink, and the gas is transmitted to the tensioning airbag 162 through the hose 163. The tensioning airbag 162 expands, driving the tensioning bolt 16 to retreat backward, pushing the tension buckle 13 to move left, thereby tightening the saw blade 5 and entering a tensioned state.

[0089] During the cutting process, the saw blade 5 rotates at high speed under the drive of the flywheel 12. The balance ruler 141 at the front end of the cutting trough 11 is fixed by the locking button 142 and adjusted through the multiple telescopic slots 1411 thereon. The protruding part of the balance ruler 141 reduces the friction resistance by matching the concave and convex parts of the guide slot 113. At the same time, the guide wheel 1431 and the limiting wheel 1433 on the stabilizing clamp 143 guide the cutting direction of the saw blade 5 to limit the shaking of the saw blade 5 during the cutting process. The wheel surface of the limiting wheel 1433 is coated with a wear-resistant coating, which can synchronously remove the foam residue generated during the cutting process as the saw blade 5 rotates. If required according to the type of foam, the injection pipe 144 at the top of the stabilizing clamp 143 can spray an appropriate amount of cutting agent to reduce the loss of the saw blade 5 and optimize the cutting effect.

[0090] After the cutting is completed, the moving frame 4 drives the cutting saw assembly 1 to move along the guide rail 6 to the next cutting position, and the above process is repeated until all the foams are cut. During the cutting process, the concave shell 111 of the cutting slot 11 is adapted to foams of different sizes through the positioning groove 116 of the elastic buckle 13 to ensure cutting accuracy. At the same time, the coaxial ring 82 on the back of the cutting saw assembly 1 cooperates with the cooperative rod 81 to provide an anti-dropping insurance for the operation of the equipment, ensuring the stability and safety of the cutting process.

[0091] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
