Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, and in particular to a traveling mechanism for a rail track machine and a foam cutting rail track machine. Background Technology

[0002] Foam is a type of foam formed from polyurethane liquid raw materials through a chemical reaction. After processing, foam forms a block structure, which usually needs to be cut into sheets using foam cutting equipment.

[0003] For example, Chinese Patent Publication No. CN2614869Y discloses a bidirectional cutting device for polyurethane foam. The machine base can move along a track and cut the foam using a grinding device on the blade holder. For larger foam volumes, it is necessary to ensure that the grinding blade can move smoothly during the cutting process in order to cut sheet-like foam of uniform thickness.

[0004] However, in actual use, the machine base moves on the track via rollers, which can easily lead to unstable operation and cause the grinding blade to shake, resulting in a reduction in cutting quality.

[0005] Therefore, how to design a technology to improve the cutting quality of foam is the technical problem that this utility model aims to solve. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a walking mechanism for a rail track machine and a foam cutting rail track machine, so as to improve the foam cutting quality of the rail track machine.

[0007] The technical solution provided by this utility model is a traveling mechanism for a track maintenance machine, comprising:

[0008] A linear guide rail, wherein a slidable slider is provided on the linear guide rail;

[0009] The walking assembly includes a walking frame and a walking drive module. The walking drive module includes a first drive motor and multiple wheel sets. Each wheel set includes two drive wheels with a rotating shaft on each drive wheel. The two rotating shafts are arranged vertically side by side and rotatably mounted on the walking frame. The multiple wheel sets are arranged sequentially along the length of the linear guide rail. The first drive motor is configured to drive the drive wheels to rotate.

[0010] The walking frame is mounted on the slider; of the two drive wheels in the same wheel set, one drive wheel is attached to one side of the linear guide rail, and the other drive wheel is attached to the other side of the linear guide rail.

[0011] This application also provides a foam cutting track cutting machine, including a tool holder with a tool belt, and a traveling mechanism for the track cutting machine; the tool holder is mounted on the traveling frame of the traveling mechanism for the track cutting machine.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: By configuring a slider on the linear guide rail, the sliding frame is mounted on the slider and slides smoothly along the linear guide rail. At the same time, the walking assembly is driven to slide along the linear guide rail by two drive wheels clamping on both sides of the linear guide rail. On the one hand, the linear guide rail can ensure that the walking frame remains stable during the sliding process to reduce up-and-down fluctuations that affect the cutting quality. On the other hand, the two drive wheels clamping on both sides of the linear guide rail can keep the walking frame synchronized and coordinated during the movement, so as to meet the requirement of smooth movement of the walking frame and improve the foam cutting quality of the rail machine.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] like Figures 1-4 As shown, this embodiment provides a rail cutting machine for thin-slicing foam, sponge, and other materials. Typically, the rail cutting machine includes a traveling mechanism 1 and a cutting mechanism 2.

[0036] The cutting mechanism 2 is used to cut the object into thin slices, while the traveling mechanism 1 is used to drive the cutting mechanism 2 to move laterally to meet the requirements of cutting the object flat.

[0037] This application makes the following structural improvements to the walking mechanism 1 and the cutting mechanism 2 to meet the cutting requirements of large-sized objects and improve the cutting quality.

[0038] Example 1: Structural improvements to the walking mechanism 1, such as... Figures 1-6 As shown, the walking mechanism 1 includes: a linear guide rail 11 and a walking component 12.

[0039] The linear guide rail 11 is equipped with a sliding block 111.

[0040] 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 multiple wheel sets. Each wheel set includes two drive wheels 1222. Each drive wheel 1222 is provided with a rotating shaft. The two rotating shafts are arranged vertically side by side and rotatably mounted on the walking frame 121. The multiple wheel sets are arranged sequentially along the length direction of the linear guide rail 11. The first drive motor 1221 is configured to drive the drive wheels 1222 to rotate. The walking frame 121 is mounted on the slider 111. In the same wheel set, one drive wheel 1222 is attached to one side of the linear guide rail 11, and the other drive wheel 1222 is attached to the other side of the linear guide rail 11.

[0041] Specifically, for the traveling frame 121 in the traveling mechanism 1, the traveling frame 121 is fixedly mounted on a slider 111 provided on the linear guide rail 11. The requirement for the traveling frame 121 to slide along the linear guide rail 11 is met by the smooth sliding of the slider 111 on the linear guide rail 11. The number of sliders 111 on the linear guide rail 11 can be set to multiple sliders 111 to support and install the traveling frame 121, depending on the installation requirements of the traveling frame 121.

[0042] The driving force for the sliding frame 121 on the linear guide rail 11 is realized by the walking drive module 122. The walking drive module 122 drives the walking frame 121 to move along the linear guide rail 11 through static friction drive between multiple wheel sets and the linear guide rail 11. Each wheel set includes two drive wheels 1222, and these two drive wheels 1222 clamp the linear guide rail 11 in the middle. Thus, under the driving action of the first drive motor 1221, the drive wheels 1222 rotate to drive the walking frame 121 to move smoothly.

[0043] In one embodiment, the walking frame 121 includes a walking base 1211 and a support frame 1212. The support frame 1212 is fixedly mounted on the walking base 1211. The drive wheel 1222 is arranged below the walking base 1211. The rotating shaft is rotatably mounted on the walking base 1211. The first drive motor 1221 is mounted on the walking base 1211. The walking base 1211 is mounted on the slider 111.

[0044] 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 mounted on the slider 111, and the walking drive module 122 is mounted on the walking base 1211; while the support frame 1212 is used to mount the cutting mechanism 2.

[0045] Furthermore, the walking base 1211 is provided with an installation compartment (unmarked), and the installation compartment is provided with a synchronous transmission assembly 123. The first drive motor 1221 is connected to each of the rotating shafts through the synchronous transmission assembly 123 to drive the wheels 1222 to rotate.

[0046] The synchronous transmission assembly 123 is configured such that the first drive motor 1221 drives each of the drive wheels 1222 to rotate synchronously, and the multiple drive wheels 1222 located on the same side of the linear guide rail 11 rotate in the same direction.

[0047] Specifically, in order to synchronously drive the drive wheels 1222 of multiple wheel sets to rotate via the first drive motor 1221, a synchronous transmission assembly 123 can be configured on the walking base 1211 to transmit the power generated by the first drive motor 1221 to each drive wheel 1222.

[0048] 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 arranged sequentially along the length direction of the linear guide rail 11 and are respectively connected to the rotating shafts on the corresponding sides of the linear guide rail 11; the plurality of second synchronous sprockets 1233 are arranged sequentially along the length direction of the linear guide rail 11 and are respectively connected to the rotating shafts on the corresponding sides of the linear guide rail 11; adjacent first synchronous sprockets 1232 are connected by a first synchronous chain ( The first synchronous sprocket 1232 and the second synchronous sprocket 1233 are connected together (not shown). The two adjacent second synchronous sprockets 1233 are connected together by the second synchronous chain (not shown). 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. The second synchronous sprocket 1233 is connected to the drive wheel 1222 on the corresponding side.

[0049] After the first drive motor 1221 is powered on, the main sprocket on the motor shaft of the first drive motor 1221 will drive the main chain 1231 to rotate, so that the main chain 1231 directly drives the corresponding first synchronous sprocket 1232 and second synchronous sprocket 1233 to rotate. 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.

[0050] Preferably, in order to enable the drive wheels 1222 arranged on both sides of the linear guide rail 11 to be driven by the same first drive motor 1221 in a synchronous and opposite direction, the main chain 1231 is fitted on one of the first synchronous sprockets 1232, which meshes with the inner part of the main chain 1231; wherein a second synchronous sprocket 1233 is arranged on the outer side of the main chain 1231, and the first synchronous sprocket 1232 meshes with the outer part of the main chain 1231.

[0051] Specifically, the main chain 1231 is fitted onto 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 and in the same direction as the main sprocket 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 will rotate synchronously and in the opposite direction to the main sprocket. In this way, a single first drive motor 1221 can synchronously drive the drive wheels 1222 on both sides of the linear guide rail 11 to rotate, smoothly moving the traveling frame 121 along the linear guide rail 11.

[0052] In some embodiments, the traveling mechanism 1 of the rail machine includes two parallel linear guide rails 11; the traveling frame 121 includes two traveling bases 1211, the support frame 1212 is a gantry frame, the support frame 1212 is disposed between the two traveling bases 1211, and each traveling base 1211 is configured with a corresponding traveling drive module 122; the traveling base 1211 is disposed on the slider 111 on the corresponding side, and the drive wheel 1222 in the traveling drive module 122 cooperates with the corresponding linear guide rail 11.

[0053] Specifically, the support frame 1212 is designed in the form of a gantry frame 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.

[0054] Furthermore, in order to improve the stability of the drive wheel 1222 and the linear guide rail 11 by generating a stable friction force, friction plates 13 are respectively provided on both sides of the linear guide rail 11, and the drive wheel 1222 abuts against the friction plate 13 on the corresponding side.

[0055] Specifically, the drive wheel 1222 rests against the friction plate 13. During rotation, the drive wheel 1222 generates static friction with the friction plate 13 to drive the traveling frame 121 to move smoothly. The friction plate 13 can be fixedly installed on both sides of the linear guide rail 11 by screws or adhesive. The friction plate 13 can contact the drive wheel 1222 to generate a sufficiently large static friction to meet the requirement of smooth movement of the traveling frame 121.

[0056] Furthermore, the linear guide 11 has an I-shaped cross-section. Specifically, the I-shaped cross-section of the linear guide 11 allows the friction plate 13 to be arranged in the groove formed on the side of the I-shaped linear guide 11.

[0057] In a preferred embodiment, in order to ensure that the drive wheel 1222 can be pressed against the linear guide rail 11, the walking frame 121 is provided with a plurality of pressing modules 14. Each pressing module 14 includes two pressing slides 141 and two pressing springs 142. The two pressing slides 141 are arranged opposite to each other. The pressing slides 141 are slidably disposed on the walking 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 toward the linear guide rail 11 to the pressing slides 141.

[0058] The shaft of the drive wheel 1222 is rotatably mounted on the clamping slide 141 on the corresponding side.

[0059] Specifically, the clamping modules are matched with the wheel sets. Two clamping slides 141 in each clamping module are distributed on both sides of the linear guide rail 11 to meet the installation requirements of the corresponding drive wheels 1222. That is, each set of clamping slides 141 and clamping springs 142 in the clamping module is used to mount the corresponding drive wheel 1222 to drive the drive wheel 1222 to rotate, using either the first synchronous sprocket 1232 or the second synchronous sprocket 1233. Under the action of the clamping springs 142, the drive wheel 1222 will be pressed against the linear guide rail 11.

[0060] Meanwhile, in order to ensure that the main chain 1231, the first synchronous chain and the second synchronous chain are always kept taut, chain tensioning methods commonly used in conventional technologies can also be configured, which will not be restricted or elaborated here.

[0061] Example 2: Structural improvements to the cutting mechanism 2, such as... Figure 1 , Figures 7-12 As shown, the cutting mechanism 2 includes:

[0062] A cutting frame 21 is provided at both ends of a first adjusting motor 211 and an adjusting slide 212. The first adjusting motor 211 is configured to drive the adjusting slide 212 to slide on the cutting frame 21.

[0063] The blade belt 24 has a ring structure, and the outer edge of the blade belt 24 forms a blade.

[0064] The drive assembly 22 includes a second drive motor 221 and two pulleys 222, the pulleys 222 being rotatably mounted on the corresponding adjusting slide 212, and the second drive motor 221 being configured to drive the pulleys 222 to rotate.

[0065] The top blade assembly 23 includes a second adjusting motor 231, an adjusting top plate 232, an upper blade plate 233, and a lower blade plate 234. A positioning space is formed between the upper blade plate 233 and the lower blade plate 234. The adjusting top plate 232 is slidably disposed between the upper blade plate 233 and the lower blade plate 234. The second adjusting motor 231 is configured to drive the adjusting top plate 232 to slide.

[0066] The upper blade and the lower blade are mounted on the cutting frame 21. The blade belt 24 is wound around the two pulleys 222 and passes through the positioning space. The adjusting top plate 232 abuts against the inner edge of the blade belt 24, and the blade is arranged on the outer side of the positioning space.

[0067] Specifically, for the cutting mechanism 2, the blade belt 24 is wound around two pulleys 222. Under the driving action of the second drive motor 221, the blade belt 24 is driven to move cyclically by the rotation of the two pulleys 222, so as to cut the object to be cut by the blade belt 24.

[0068] During the cutting process, the blade belt 24 experiences wear and requires sharpening, causing the blade edge of the blade belt 24 to retract. At this point, the position of the blade belt 24 is adjusted by the top blade assembly 23. Specifically, the top blade assembly 23 drives the adjusting top plate 232 to move via the second adjusting motor 231, so that the adjusting top plate 232 rests against the inner edge of the blade belt 24, allowing the blade edge of the blade belt 24 to move forward to achieve an accurate cutting position.

[0069] When adjusting the position of the cutter belt 24 by adjusting the top plate 232, the top plate 232 abuts against the cutter belt 24 between the upper cutter plate 233 and the lower cutter plate 234. The cutter belt 24 performs the cutting operation in the positioning space formed by the upper cutter plate 233 and the lower cutter plate 234, which can ensure the smooth operation of the cutter belt 24.

[0070] Meanwhile, after the blade belt 24 moves to position the cutting edge at the set cutting position, to ensure that the blade belt 24 remains basically centered on the pulley 222 during cyclic movement, the position of the pulleys 222 at both ends can be further adjusted by adjusting the slide block 212 to match the movement distance of the blade belt 24. Specifically, the first adjusting motor 211 can drive the adjusting slide block 212 to move to match the feed amount of the blade belt 24, so that the blade belt 24 remains basically centered on the pulley 222 during cyclic movement, improving the running stability of the blade belt 24 and thus better improving the cutting quality.

[0071] The adjusting slide 212 is provided with a rotatable mounting shaft, and the pulley 222 is provided on the corresponding mounting shaft. The adjusting slide 212 is slidably provided on the cutting frame 21 along the axial direction of the mounting shaft.

[0072] In some embodiments, the adjusting top plate 232 is provided with a plurality of parallel-arranged top knife rods 235;

[0073] The second adjusting motor 231 is configured to drive multiple top cutter rods 235 to move synchronously to push the adjusting top plate 232 to slide.

[0074] Specifically, since the cutting surface of the blade belt 24 is relatively wide during cutting, the width of the positioning space formed by the upper blade plate 233 and the lower blade plate 234 must meet the cutting width requirements of the blade belt 24. Correspondingly, the width of the adjusting top plate 232 needs to meet the pushing requirements of the blade belt 24 in the positioning space, resulting in a larger width of the adjusting top plate 232. When adjusting the position of the blade belt 24, in order to ensure that the blade belt 24 at different positions in the positioning space can move synchronously, multiple pusher rods 235 are arranged side by side along the width direction on the adjusting top plate 232. Driven by the second adjusting motor 231, each pusher rod 235 can simultaneously apply a pushing force to the adjusting top plate 232, so that the adjusting top plate 232 can smoothly push the blade belt 24 to move.

[0075] The top cutter assembly 23 further includes a worm gear 236, which is connected to the second adjusting motor 231 in a transmission manner; each top cutter rod 235 is provided with a lead screw 237, and a threaded sleeve 238 is threadedly connected to the lead screw 237. A worm wheel 239 is provided on the threaded sleeve 238, and the worm wheel 239 meshes with the worm gear 236.

[0076] Specifically, the second adjusting motor 231 can drive the worm 236 to rotate. The worm 236 meshes with each worm wheel 239, thereby driving each thread sleeve 238 to rotate synchronously. The rotating thread sleeve 238 will drive each top cutter bar 235 to move synchronously by cooperating with the thread rod 237, so as to enable the driving adjusting top plate 232 to smoothly push the cutter belt 24 located in the positioning space.

[0077] In addition, the top blade assembly 23 also includes a blade holder 230, the worm gear 236 is rotatably mounted on the blade holder 230, the upper blade plate 233 and the lower blade plate 234 are respectively mounted on the front edge of the blade holder 230, the top blade rod 235 and the adjusting top plate 232 are respectively slidably mounted on the blade holder 230, the second adjusting motor 231 is mounted at the end of the blade holder 230, and the blade holder 230 is laterally mounted on the cutting frame 21.

[0078] Specifically, the blade holder 230 serves as the main mounting structure for the top blade assembly 23. The blade holder 230 is mounted and fixed on the cutting machine frame 21 and located between the two pulleys 222. The upper blade plate 233 and the lower blade plate 234 are fixedly mounted on the front side of the blade holder 230. The blade holder 230 is provided with corresponding sliding grooves to meet the sliding installation requirements of the top plate 232.

[0079] Furthermore, in order to control the position of the blade during use, a photoelectric switch 25 is also provided on the cutting frame 21. The photoelectric switch 25 is configured to detect the position of the blade extending outside the positioning space.

[0080] Specifically, the photoelectric switch 25 can check the position of the blade in the blade belt 24 during the cutting process, and trigger the control of the second adjustment motor 231 to stop running after the blade reaches the set cutting position.

[0081] Similarly, when the blade belt 24 needs to be replaced after a long period of use, the adjusting top plate 232 needs to be reset. In order to control the reset position of the adjusting top plate 232, a proximity sensor 26 is also provided on the blade holder 230. The proximity sensor 26 is configured to detect the reset position of the top blade rod 235.

[0082] Specifically, after the blade belt 24 is disassembled and before a new blade belt 24 is installed, the second adjusting motor 231 rotates in the reverse direction, causing the top blade rod 235 to move in the reverse direction until it is detected by the proximity sensor 26, triggering the second adjusting motor 231 to stop running. At this time, the adjusting top plate 232 reaches its original position.

[0083] In one embodiment, in order to precisely control the moving distance of the adjusting slide 212, rotatable lead screws 213 are respectively provided at both ends of the cutting frame 21. The adjusting slide 212 is provided with threaded holes, and the lead screws 213 are threadedly connected in the threaded holes. The first adjusting motor 211 is connected to the lead screws 213 in a transmission connection.

[0084] Specifically, when adjusting the movement of the two pulleys 222 to match the movement of the blade belt 24, the first adjusting motor 211 drives the lead screw 213 to rotate through the reducer, so as to drive the adjusting slide 212 to move precisely through the lead screw 213.

[0085] 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 drive motor 221 and the driving pulley, and the second drive motor 221 is connected to the driving pulley in a driving connection; the other adjusting slide 212 is provided with a tensioning screw 214 and a tensioning slide 215, the tensioning slide 215 is slidably disposed on the adjusting slide 212, the tensioning screw 214 is rotatably disposed on the adjusting slide 212 and threadedly connected to the tensioning slide 215, and the driven pulley is rotatably disposed on the tensioning slide 215;

[0086] The blade belt 24 is wound around the driving wheel and the driven wheel.

[0087] Specifically, for the pulleys 222 distributed on both sides of the adjusting slide 212, the pulley 222 adjacent to the second drive motor 221 serves as the driving pulley. The second drive motor 221 drives the driving pulley to rotate, and the driving pulley drives the driven pulley to rotate through the blade belt 24. For the adjusting slide 212 on which the driven pulley is installed, in order to facilitate the installation and removal of the blade belt 24, the adjusting slide 212 is also additionally equipped with a tensioning slide 215. The driven pulley is installed on the tensioning slide 215, and the tensioning slide 215 is driven by the tensioning screw 214 to achieve the movement of the tensioning slide 215 on the adjusting slide 212.

[0088] Example 3: Combining Example 1 and Example 2 above, the rail track machine can simultaneously employ the traveling mechanism 1 in Example 1 and the cutting mechanism 2 in Example 2.

[0089] In order to meet the cutting requirements of different heights, the walking frame 121 is equipped with a lifting mechanism 3, the lifting mechanism 3 is equipped with a lifting part, and the cutting frame 21 is mounted on the lifting part.

[0090] Specifically, the cutting frame 21 can be moved up and down by the lifting mechanism 3 to adjust the height of the cutting position of the blade belt 24. The lifting mechanism 3 can be a ball screw 237 lift, a spiral screw 237 lift, etc., which will not be limited or described in detail here.

[0091] In addition, in order to facilitate the carrying of the material to be cut during the cutting process, a carrying platform 4 can be configured, which is arranged below the cutting mechanism 2 to place the material to be cut.
