Technical Field

[0001] The utility model relates to the technical field of machinery, in particular to a rail cutting mechanism and a foam rail cutting machine. Background Art

[0002] Foam is a kind of foam formed by chemical reaction of polyurethane liquid raw materials, referred to as foam. After processing and molding, the foam forms a block structure, and usually needs to be switched to form a sheet with the help of foam cutting equipment. For example: Chinese Patent Publication No. CN209831785U discloses a transmission device of a foam vertical cutting machine, which is equipped with a ring saw blade for cutting. At the same time, it is also equipped with a grinding motor to drive a grinding wheel to grind the ring saw blade to ensure that the sharpness of its blade meets the cutting requirements. During use, the blade will become blunt as the use time increases. For this reason, it is necessary to grind the blade with a grinding wheel. As the use time increases, the blade will retreat due to grinding, which makes the cutting position of the blade cutting the foam inaccurate, resulting in reduced cutting quality. In view of this, how to design a technology to improve the cutting quality of foam is the technical problem to be solved by the present invention. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a cutting mechanism for a rail machine and a foam rail cutting machine, so as to improve the foam cutting quality of the rail machine.

[0004] The technical solution provided by the utility model is a rail cutting mechanism, which is characterized by comprising:

[0005] A cutting frame, wherein a first adjustment motor and an adjustment slide are respectively provided at both ends of the cutting frame, wherein the first adjustment motor is configured to drive the adjustment slide to slide on the cutting frame;

[0006] A knife belt, wherein the knife belt is annular in structure, and the outer edge of the knife belt forms a cutting edge;

[0007] a drive assembly comprising a second drive motor and two pulleys, wherein the pulleys are rotatably disposed on corresponding adjustment slides, and the second drive motor is configured to drive the pulleys to rotate;

[0008] A top knife assembly, the top knife assembly comprising a second adjustment motor, an adjustment top plate, an upper knife plate and a lower knife plate, wherein a positioning space is formed between the upper knife plate and the lower knife plate, the adjustment top plate is slidably disposed between the upper knife plate and the lower knife plate, and the second adjustment motor is configured to drive the adjustment top plate to slide;

[0009] Wherein, the upper blade and the lower blade are arranged on the cutting frame, the blade belt is wound around the two pulleys, the blade belt passes through the positioning space, the adjustment top plate rests against the inner edge of the blade belt, and the blade is arranged on the outside of the positioning space.

[0010] The present application also provides a foam rail cutting machine, which includes a traveling frame and the above-mentioned rail machine cutting mechanism; the rail machine cutting mechanism is arranged on the traveling frame.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are: the knife belt is pressed against the knife blade by the adjusting top plate of the top knife assembly, and when the knife belt is worn and the blade retracts, the second adjusting motor can be used to drive the adjusting top plate to eject the knife belt, so as to ensure that the knife belt always remains in the accurate cutting position. At the same time, after the knife belt is ejected, in order to ensure that the knife belt can rotate smoothly under the drive of the two pulleys, the pulleys will move synchronously with the adjusting slide to match the ejection amount of the knife belt, thereby ensuring that the knife belt can be basically centered on the pulley, so as to improve the running stability of the knife belt and improve the foam cutting quality of the rail machine.

[0033] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0034] like Figures 1-4 As shown, this embodiment provides a track machine, which is used to cut foam, sponge and other materials to be cut into thin slices. Generally, the track machine includes: a walking mechanism 1 and a cutting mechanism 2.

[0035] The cutting mechanism 2 is used to perform thin-slice cutting on the object to be cut, and the traveling mechanism 1 is used to drive the cutting mechanism 2 to move horizontally to meet the working requirement of flatly cutting the object to be cut.

[0036] The present application makes the following structural improvements to the walking mechanism 1 and the cutting mechanism 2 respectively, so as to meet the cutting requirements of large-sized objects to be cut and improve the cutting quality.

[0037] Embodiment 1, for the structural improvement of the walking mechanism 1, such as Figures 1-6 As shown, the walking mechanism 1 includes: a linear guide rail 11 and a walking assembly 12.

[0038] The linear guide rail 11 is provided with a slidable slider 111 .

[0039] The walking assembly 12 includes a walking frame 121 and a walking drive module 122, the walking drive module 122 includes a first drive motor 1221 and a plurality of wheel groups, the wheel group includes two driving wheels 1222, the driving wheels 1222 are provided with a rotating shaft, the two rotating shafts are arranged vertically side by side and are rotatably provided on the walking frame 121, and the plurality of wheel groups are arranged in sequence along the length direction of the linear guide 11, the first drive motor 1221 is configured to drive the driving wheels 1222 to rotate; the walking frame 121 is provided on the slider 111; the two driving wheels 1222 in the same wheel group, one of the driving wheels 1222 is abutted against one side of the linear guide 11, and the other driving wheel 1222 is abutted against the other side of the linear guide 11;

[0040] Specifically, the traveling frame 121 in the traveling mechanism 1 is fixedly mounted on a slider 111 provided on the linear guide rail 11, and relies on the slider 111 to slide smoothly on the linear guide rail 11 to meet the requirement that the traveling frame 121 slides along the linear guide rail 11. The number of sliders 111 on the linear guide rail 11 can be adjusted to meet the installation requirements of the traveling frame 121. A plurality of sliders 111 can be provided to support and install the traveling frame 121.

[0041] The driving force for the traveling frame 121 to slide on the linear guide 11 is provided by the traveling drive module 122. The traveling drive module 122 drives the traveling frame 121 along the linear guide 11 by static friction between multiple wheel sets and the linear guide 11. Each wheel set includes two driving wheels 1222, which sandwich the linear guide 11. Thus, driven by the first drive motor 1221, the driving wheels 1222 rotate to drive the traveling frame 121 to move smoothly.

[0042] In one embodiment, the walking frame 121 includes a walking base 1211 and a support frame 1212, the support frame 1212 is fixedly set on the walking base 1211, the driving wheel 1222 is arranged below the walking base 1211, the rotating shaft is rotatably set on the walking base 1211, the first driving motor 1221 is set on the walking base 1211; the walking base 1211 is set on the slider 111.

[0043] Specifically, in order to meet the installation requirements, the walking frame 121 includes a walking base 1211 and a support frame 1212; the walking base 1211 is installed on the slider 111, and the walking drive module 122 is installed on the walking base 1211; and the support frame 1212 is used to install the cutting mechanism 2.

[0044] Furthermore, an installation compartment (not marked) is provided on the walking base 1211, and a synchronous transmission assembly 123 is provided in the installation compartment. The first drive motor 1221 is connected to each of the rotating shafts through the synchronous transmission assembly 123 to drive the drive wheel 1222 to rotate;

[0045] The synchronous transmission assembly 123 is configured such that the first driving motor 1221 drives each of the driving wheels 1222 to rotate synchronously and the plurality of driving wheels 1222 located on the same side of the linear guide rail 11 rotate in the same direction.

[0046] Specifically, in order to synchronously drive the driving wheels 1222 of multiple wheel sets to rotate through the first driving motor 1221, a synchronous transmission assembly 123 can be configured on the walking base 1211 to transmit the power generated by the first driving motor 1221 to each driving wheel 1222 through the synchronous transmission assembly 123.

[0047] Specifically, the synchronous transmission assembly 123 includes a main chain 1231, a plurality of first synchronous sprockets 1232 and a plurality of second synchronous sprockets 1233; the plurality of first synchronous sprockets 1232 are sequentially arranged along the length direction of the linear guide 11 and are respectively connected to the rotating shafts on the corresponding sides of the linear guide 11, and the plurality of second synchronous sprockets 1233 are sequentially arranged along the length direction of the linear guide 11 and are respectively connected to the rotating shafts on the corresponding sides of the linear guide 11; two adjacent first synchronous sprockets 1232 are connected by a first synchronous chain ( The first and second synchronous sprockets 1232 and 1233 are connected together by a second synchronous chain (not marked); the main chain 1231 is connected to the first synchronous sprocket 1232 and the second synchronous sprocket 1233 respectively, the motor shaft of the first drive motor 1221 is provided with a main sprocket (not shown), the main chain 1231 is connected to the main sprocket, the first synchronous sprocket 1232 is connected to the drive wheel 1222 on the corresponding side, and the second synchronous sprocket 1233 is connected to the drive wheel 1222 on the corresponding side.

[0048] When the first drive motor 1221 is powered on, the main sprocket on the motor shaft of the first drive motor 1221 drives the main chain 1231 to rotate, thereby directly driving the corresponding first synchronous sprocket 1232 and second synchronous sprocket 1233 to rotate through the main chain 1231. For the other first synchronous sprockets 1232, power is transmitted through the first synchronous chain, so that each first synchronous sprocket 1232 drives the corresponding drive wheel 1222 to rotate; similarly, for the other second synchronous sprockets 1233, power is transmitted through the second synchronous chain, so that each second synchronous sprocket 1233 drives the corresponding drive wheel 1222 to rotate.

[0049] Preferably, in order to achieve that the driving wheels 1222 arranged on both sides of the linear guide rail 11 can be synchronously and in opposite directions provided with driving force by the same first driving motor 1221, the main chain 1231 is sleeved on one of the first synchronous sprockets 1232, and the first synchronous sprocket 1232 is engaged with the inner part of the main chain 1231; one of the second synchronous sprockets 1233 is arranged on the outer side of the main chain 1231, and the first synchronous sprocket 1232 is engaged with the outer part of the main chain 1231.

[0050] Specifically, the main chain 1231 is mounted on one of the first synchronous sprockets 1232. Thus, the first drive motor 1221 drives the main sprocket to rotate, causing the first synchronous sprocket 1232 to rotate synchronously with the main sprocket in the same direction via the main chain 1231. Simultaneously, the outer side of the main chain 1231 abuts against one of the second synchronous sprockets 1233. Driven by the main chain 1231, the second synchronous sprocket 1233 rotates synchronously with the main sprocket in a counter-rotating direction. In this way, the single first drive motor 1221 can synchronously drive the drive wheels 1222 on both sides of the linear guide 11 to rotate, thereby smoothly driving the traveling frame 121 to move along the linear guide 11.

[0051] In some embodiments, the track machine walking mechanism 1 includes two parallel linear guide rails 11; the walking frame 121 includes two walking bases 1211, the support frame 1212 is a gantry, the support frame 1212 is arranged between the two walking bases 1211, and each walking base 1211 is configured with a corresponding walking drive module 122; the walking base 1211 is arranged on the slider 111 on the corresponding side, and the driving wheel 1222 in the walking drive module 122 cooperates with the corresponding linear guide rail 11.

[0052] Specifically, the support frame 1212 is in the form of a gantry to better meet the installation requirements of the cutting mechanism 2. The support frame 1212 is supported by two walking bases 1211 at the bottom and can slide smoothly along the two linear guide rails 11.

[0053] Furthermore, in order to increase the stable friction force generated between the driving wheel 1222 and the linear guide rail 11 to improve the driving stability, friction plates 13 are respectively provided on both sides of the linear guide rail 11, and the driving wheel 1222 is abutted against the friction plates 13 on the corresponding side.

[0054] Specifically, the drive wheel 1222 abuts against the friction plate 13. During rotation, the drive wheel 1222 generates static friction with the friction plate 13, thereby driving the traveling frame 121 to move smoothly. The friction plate 13 can be fixed to both sides of the linear guide 11 by screws or adhesive. The friction plate 13 can contact the drive wheel 1222 to generate sufficient static friction to ensure smooth movement of the traveling frame 121.

[0055] Furthermore, the cross section of the linear guide rail 11 is an I-shaped structure. Specifically, the cross section of the linear guide rail 11 is an I-shaped structure, so that the friction plate 13 can be arranged in a groove formed on the side of the I-shaped linear guide rail 11.

[0056] In a preferred embodiment, in order to ensure that the driving wheel 1222 can be pressed against the linear guide rail 11, a plurality of pressing modules 14 are provided on the traveling frame 121, and each of the pressing modules 14 includes two pressing slides 141 and two pressing springs 142. The two pressing slides 141 are arranged opposite to each other, and the pressing slides 141 are slidably provided on the traveling frame 121 perpendicular to the length direction of the linear guide rail 11. The pressing springs 142 abut against the pressing slides 141 and are configured to apply a spring force to the pressing slides 141 toward the linear guide rail 11.

[0057] The rotating shaft of the driving wheel 1222 is rotatably disposed on the pressing slide 141 on the corresponding side.

[0058] Specifically, the clamping module matches the wheel assembly. The two clamping slides 141 in each clamping module are located on either side of the linear guide rail 11 to accommodate the corresponding drive wheel 1222. Specifically, each set of clamping slides 141 and clamping springs 142 in the clamping module is used to mount the corresponding drive wheel 1222, thereby driving the first or second synchronous sprocket 1232 or 1233 to rotate the drive wheel 1222. Under the action of the clamping springs 142, the drive wheel 1222 is pressed against the linear guide rail 11.

[0059] At the same time, in order to ensure that the main chain 1231, the first synchronous chain and the second synchronous chain always remain in a tensioned state, a chain tensioning method commonly used in conventional technology can also be configured, which will not be limited or elaborated here.

[0060] Embodiment 2, for the structural improvement of the cutting mechanism 2, such as Figure 1 、 Figure 7-12 As shown, the cutting mechanism 2 includes:

[0061] A cutting frame 21, wherein a first adjustment motor 211 and an adjustment slide 212 are respectively provided at both ends of the cutting frame 21, wherein the first adjustment motor 211 is configured to drive the adjustment slide 212 to slide on the cutting frame 21;

[0062] A knife band 24, wherein the knife band 24 is annular in structure, and the outer edge of the knife band 24 forms a cutting edge;

[0063] The drive assembly 22 includes a second drive motor 221 and two pulleys 222 . The pulleys 222 are rotatably disposed on the corresponding adjustment slides 212 . The second drive motor 221 is configured to drive the pulleys 222 to rotate.

[0064] The top knife assembly 23 includes a second adjustment motor 231, an adjustment top plate 232, an upper knife plate 233, and a lower knife plate 234. A positioning space is formed between the upper knife plate 233 and the lower knife plate 234. The adjustment top plate 232 is slidably disposed between the upper knife plate 233 and the lower knife plate 234. The second adjustment motor 231 is configured to drive the adjustment top plate 232 to slide.

[0065] Among them, the upper knife plate and the lower knife plate are arranged on the cutting frame 21, the knife belt 24 is wound around the two pulleys 222, the knife belt 24 passes through the positioning space, the adjustment top plate 232 rests on the inner edge of the knife belt 24, and the blade is arranged on the outside of the positioning space.

[0066] Specifically, for the cutting mechanism 2 , the knife belt 24 is wound around two pulleys 222 . Driven by the second drive motor 221 , the two pulleys 222 rotate to drive the knife belt 24 to move in a circular motion, so that the knife belt 24 can cut the object to be cut.

[0067] During the cutting process, the blade belt 24 wears and needs to be sharpened, causing the blade of the blade belt 24 to retract. At this time, the position of the blade belt 24 is adjusted by the top blade assembly 23. Specifically, the top blade assembly 23 drives the adjustment top plate 232 to move via the second adjustment motor 231. The adjustment top plate 232 abuts against the inner edge of the blade belt 24, allowing the blade of the blade 24 to move forward to the accurate cutting position.

[0068] When the position of the knife belt 24 is adjusted by adjusting the top plate 232, the top plate 232 is adjusted to press the knife belt 24 between the upper knife plate 233 and the lower knife plate 234, and the knife belt 24 performs the feed operation in the positioning space formed by the upper knife plate 233 and the lower knife plate 234, which can ensure the smooth operation of the knife belt 24.

[0069] At the same time, after the knife belt 24 moves so that the blade is at the set cutting position, in order to ensure that the knife belt 24 is always substantially centered on the pulley 222 and circulates, the pulleys 222 at both ends can be further adjusted by adjusting the slide 212 to match the movement distance of the knife belt 24. Specifically, the first adjustment motor 211 can drive the adjustment slide 212 to move to match the feed amount of the knife belt 24, so that the knife belt 24 is always substantially centered on the pulley 222 and circulates, improving the running stability of the knife belt 24 and further improving the cutting quality.

[0070] The adjusting slide 212 is provided with a rotatable mounting shaft, the pulley 222 is provided on the corresponding mounting shaft, and the adjusting slide 212 is slidably provided on the cutting frame 21 along the axial direction of the mounting shaft.

[0071] In some embodiments, the adjusting top plate 232 is provided with a plurality of top cutter rods 235 arranged in parallel;

[0072] The second adjustment motor 231 is configured to drive the plurality of top blade rods 235 to move synchronously to push the adjustment top plate 232 to slide.

[0073] Specifically, because the width of the cutting surface of the knife belt 24 is relatively wide during cutting, the width of the positioning space formed by the upper knife plate 233 and the lower knife plate 234 must meet the cutting width requirements of the knife belt 24. Accordingly, the width of the adjustable top plate 232 must meet the pushing requirements of the knife belt 24 in the positioning space, resulting in a relatively large width of the adjustable top plate 232. When adjusting the position of the knife belt 24, in order to ensure that the knife belt 24 at different positions in the positioning space can move synchronously, a plurality of top knife rods 235 are arranged side by side along the width direction on the adjustable top plate 232. Driven by the second adjustment motor 231, each top knife rod 235 can simultaneously apply a thrust to the adjustable top plate 232, so that the adjustable top plate 232 can smoothly push the knife belt 24 to move.

[0074] In which, the top knife assembly 23 also includes a worm 236, which is transmission-connected to the second adjusting motor 231; each of the top knife rods 235 is provided with a screw rod 237, and a threaded sleeve 238 is threadedly connected to the screw rod 237, and a worm wheel 239 is provided on the threaded sleeve 238, and the worm wheel 239 is engaged with the worm 236.

[0075] Specifically, the second adjusting motor 231 can drive the worm 236 to rotate, and the worm 236 engages with each worm wheel 239 to drive each wire sleeve 238 to rotate synchronously. The rotating wire sleeve 238 will drive each top knife rod 235 to move synchronously by cooperating with the screw rod 237, so as to realize the driving adjustment top plate 232 to smoothly push the knife belt 24 located in the positioning space.

[0076] In addition, the top knife assembly 23 also includes a knife seat 230, the worm 236 is rotatably arranged on the knife seat 230, the upper knife plate 233 and the lower knife plate 234 are respectively arranged on the front side edge of the knife seat 230, the top knife rod 235 and the adjustment top plate 232 are respectively slidably arranged on the knife seat 230, the second adjustment motor 231 is arranged at the end of the knife seat 230, and the knife seat 230 is horizontally arranged on the cutting frame 21.

[0077] Specifically, the knife seat 230 serves as the main installation structure of the top knife assembly 23. The knife seat 230 will be installed and fixed on the cutting frame 21 and located between the two pulleys 222. The upper knife plate 233 and the lower knife plate 234 are fixedly installed on the front side of the knife seat 230. Corresponding sliding grooves are opened on the knife seat 230 to meet the sliding installation requirements of the adjustment top plate 232.

[0078] Furthermore, in order to control the position of the blade during use, a photoelectric switch 25 is further provided on the cutting frame 21 , and the photoelectric switch 25 is configured to detect the position of the blade extending outside the positioning space.

[0079] Specifically, the photoelectric switch 25 can detect the position of the blade of the knife belt 24 during the cutting process, and trigger the second regulating motor 231 to stop running after the blade reaches the set cutting position.

[0080] Similarly, when the knife belt 24 needs to be replaced after being used for a long time, the adjustment top plate 232 needs to be reset. In order to control the reset position of the adjustment top plate 232, a proximity sensor 26 is also provided on the knife seat 230. The proximity sensor 26 is configured to detect the reset position of the top knife rod 235.

[0081] Specifically, after the knife belt 24 is removed and before a new knife belt 24 is replaced, the second adjusting motor 231 rotates in the opposite direction, causing the top knife rod 235 to move in the opposite direction until it is detected by the proximity sensor 26 and a trigger is generated to control the second adjusting motor 231 to stop running. At this time, the adjusting top plate 232 reaches its original position.

[0082] In one embodiment, in order to accurately control the moving distance of the adjustment slide 212, a rotatable screw 213 is respectively provided at both ends of the cutting frame 21, a threaded hole is provided on the adjustment slide 212, and the screw 213 is threadedly connected to the threaded hole, and the first adjustment motor 211 is transmission-connected to the screw 213.

[0083] Specifically, when the two pulleys 222 are adjusted to match the movement of the knife belt 24 , the first adjustment motor 211 drives the lead screw 213 to rotate through the speed reducer, so as to drive the adjustment slide 212 to move precisely through the lead screw 213 .

[0084] In another embodiment, the two pulleys 222 are divided into a driving pulley and a driven pulley; one of the adjusting slides 212 is provided with the second driving motor 221 and the driving pulley, and the second driving motor 221 is in transmission connection with the driving pulley; the other adjusting slide 212 is provided with a tensioning screw 214 and a tensioning slide 215, the tensioning slide 215 is slidably provided on the adjusting slide 212, the tensioning screw 214 is rotatably provided on the adjusting slide 212 and is threadedly connected to the tensioning slide 215, and the driven pulley is rotatably provided on the tensioning slide 215;

[0085] The knife belt 24 is wound around the driving wheel and the driven wheel.

[0086] Specifically, the pulleys 222 located on both sides of the adjustment slide 212 are located adjacent to the second drive motor 221 and serve as the driving pulleys. The second drive motor 221 drives the driving pulleys, which in turn drive the driven pulleys via the knife belt 24. Furthermore, the adjustment slide 212 on which the driven pulleys are mounted is additionally equipped with a tensioning slide 215 to facilitate assembly and disassembly of the knife belt 24. The driven pulleys are mounted on the tensioning slide 215, which is driven by a tensioning screw 214 to adjust the movement of the tensioning slide 215 on the adjustment slide 212.

[0087] In the third embodiment, in combination with the first and second embodiments, the track-guided machine may simultaneously adopt the traveling mechanism 1 in the first embodiment and the cutting mechanism 2 in the second embodiment.

[0088] In order to meet the cutting requirements at different heights, a lifting mechanism 3 is provided on the traveling frame 121 , a lifting portion is provided on the lifting mechanism 3 , and the cutting frame 21 is provided on the lifting portion.
