Description

Technical Field

[0001] The invention relates to the technical field of sponge processing, and in particular to a sponge crusher. Background Art

[0002] Sponge particles have good elasticity and support, and can be adaptively adjusted according to the user's body shape and posture to provide support that is more in line with the human body. In the field of furniture processing, sofas, mattresses, etc. are one of the main application areas of sponge particle filling. Sofa cushions and backrests filled with sponge particles can provide a soft touch and uniform support, effectively relieving fatigue caused by long-term sitting. At present, when a whole piece of sponge is granulated, since the sponge may contact the cutter irregularly during the cutting process, some sponges will contact the cutter multiple times, resulting in unnecessary multiple cutting, making the final sponge particle size uniform. Poor uniformity of sponge particle size will affect the use effect after filling.

[0003] In the prior art, the patent document with the authorization announcement number CN217368668U discloses a sponge pelletizing device, including a frame and a guide mechanism, a traction mechanism and a pelletizing mechanism arranged on the frame in sequence along the sponge transmission direction; the pelletizing mechanism includes a roller cutter; a static electricity removal mechanism is provided on one side of the roller cutter; the static electricity removal mechanism includes a spray pipe; the spray pipe is provided with an atomizing nozzle spraying toward the cutter. When it is used, it sprays water mist on the roller cutter to avoid the sponge being adsorbed on the roller cutter due to static electricity, resulting in multiple cutting. It can improve the pelletizing effect to a certain extent, but the spray may remain on the sponge particles, and the residual moisture needs to be removed in the subsequent treatment, which increases the complexity and cost of the treatment. In addition, spraying water mist on the roller cutter for a long time may affect its service life. Summary of the invention

[0004] The invention provides a sponge crusher to solve the technical problem in the prior art that the uniformity of sponge particle size is poor after the sponge is granulated by the sponge crusher.

[0005] In order to solve the above problems, the present invention provides a sponge crusher adopting the following technical solutions:

[0006] The utility model comprises a frame and a conveying mechanism which is arranged on the frame and is used for conveying sponges. A cutter assembly for cutting sponges is arranged at the output end of the conveying mechanism. The cutter assembly comprises a first cutter and a second cutter. The first cutter and the second cutter are respectively distributed on the upper side and the lower side of the sponge. When the first cutter and the second cutter cut from the upper surface and the lower surface of the sponge respectively, non-penetrating cutting seams are formed on the upper surface and the lower surface of the sponge, and the cutting seams on the upper surface and the cutting seams on the lower surface of the sponge are relatively distributed.

[0007] A dividing mechanism is provided at one end of the cutter assembly away from the conveying mechanism, and the dividing mechanism includes a separating belt for separating the connecting part at the sponge cutting seam, and the separating belt is inclined downward from one end close to the cutter assembly to the other end, and there are a plurality of separating belts distributed at intervals, and supporting end plates for assisting sponge separation are provided between adjacent separating belts.

[0008] A reciprocating cutter mechanism for cutting the sponge is arranged below one end of the dividing mechanism close to the cutter assembly, and the cutting direction of the reciprocating cutter mechanism is perpendicular to the cutting direction of the cutter assembly.

[0009] By adopting the above technical scheme, non-through cutting is performed from the upper and lower surfaces of the sponge by the first cutter and the second cutter respectively, forming relatively distributed cutting seams, thereby avoiding shape deviation that may be caused by complete cutting at one time, and providing a good foundation for subsequent sponge segmentation, so that the final sponge particle shape is more regular and consistent.

[0010] The non-penetrating cutting retains the partial connection at the sponge cutting seam, that is, a breakable connection is formed at the cutting seam. This connection method can maintain the integrity of the sponge during transportation and prevent the sponge from scattering due to complete cutting. It helps to reduce damage to the sponge during transportation and subsequent processing and improve the finished granulation effect.

[0011] In addition, the downward inclined separation belt design allows the sponge to be naturally pressed and separated at the easily breakable connections during transportation, that is, the easily breakable connections are disconnected and separated into particles, avoiding the sponge from being cut multiple times to form irregular particles.

[0012] Furthermore, a pressure roller for compressing the sponge downward is provided at one end of the separation belt close to the cutting knife assembly, and an active roller is provided at the other end of the separation belt. The pressure roller and the active roller are connected through a separation belt transmission. Both the pressure roller and the active roller are provided with an annular groove for limiting the separation belt. A support plate is fixedly provided on the frame and is located below the pressure roller. The thickness of the sponge is compressed when it passes between the pressure roller and the support plate, and the reciprocating cutting knife mechanism is used to cut the sponge after the thickness is compressed.

[0013] By adopting the above technical solution, during the rotation process, the pressure roller not only drives the separation belt to be transmitted, but also compresses the sponge downward, making the sponge more compact and smooth before entering the reciprocating cutter mechanism, thereby reducing the cutting difficulty and improving the cutting accuracy.

[0014] Furthermore, a pressure plate is provided on the side of the pressure roller close to the active roller, and both ends of the pressure plate are correspondingly fixed on the frame, and the bottom end surface of the pressure plate is flush with the bottom end of the pressure roller. An auxiliary plate is provided on the side of the pressure plate close to the pressure roller, and the auxiliary plate is distributed relative to the annular groove, and the auxiliary plate includes a horizontal plate and an arc plate, and the arc plate is correspondingly clamped in the annular groove, and the outer surface of the arc plate on the side away from the center of the pressure roller is flush with the outer circumferential surface of the pressure roller.

[0015] A wedge plate is provided on one side of the pressing plate away from the pressing roller.

[0016] Furthermore, the reciprocating cutting mechanism includes a cutting plate corresponding to the bottom of the pressure plate and a telescopic member fixed under the support plate and driving the cutting plate to move up and down, the top edge of the cutting plate is a cutting edge, the support plate and the support end plate are laterally spaced apart and a guide groove is formed between the support plate and the support end plate to allow the cutting plate to pass vertically.

[0017] An avoidance groove opposite to the knife plate is formed on the lower end surface of the pressing plate.

[0018] By adopting the above technical solution, a pressure plate is set. On the one hand, the arc plate included in the pressure plate works together with the pressure roller to make the sponge flatter during the compression process, reducing the deformation of the sponge and helping to improve the cutting effect. On the other hand, the knife plate and the pressure plate are vertically opposite to each other and are provided with an avoidance groove, which ensures the cutting effect while avoiding the blade from facing outward and affecting the safety of use.

[0019] Furthermore, a support shaft is provided on the side of the active roller close to the pressure roller, and the support shaft is located above the lower separation belt. A plurality of groups of baffle plates are fixedly sleeved on the support shaft, and each group of baffle plates consists of two symmetrically distributed baffle plates, and the two baffle plates are located on both sides of the separation belt.

[0020] By adopting the above technical solution, a baffle plate is set to prevent the cut sponge from entering the active roller along the lower separation belt due to static electricity and other reasons, thereby causing equipment failure, thereby reducing downtime caused by equipment failure and improving production efficiency.

[0021] Furthermore, the first cutter includes a first rotating shaft rotatably supported by a frame, the second cutter includes a second rotating shaft rotatably supported by a frame, a first circular blade is fixedly sleeved on the first rotating shaft and is spaced apart, and a second circular blade is fixedly sleeved on the second rotating shaft and is spaced apart, the first circular blade and the second circular blade are spaced apart in the horizontal direction, the first circular blade and the second circular blade are correspondingly distributed and the vertical spacing is 3mm-5mm.

[0022] By adopting the above technical solution, the first circular blade and the second circular blade cut from the upper and lower surfaces respectively, which can significantly reduce the depth that a single blade needs to penetrate the sponge each time it cuts, which improves the cutting effect on the one hand, and reduces the wear and heat accumulation of the first circular blade and the second circular blade on the other hand, thereby extending the service life of the blade. Furthermore, the vertical spacing forms an easily breakable connection at the cutting seam, making it easier for the sponge materials on both sides of the cutting seam to separate when subjected to external force, providing a good foundation for subsequent sponge segmentation.

[0023] Furthermore, cooling mechanisms are fixedly provided on the frame and are respectively located above the first cutter and below the second cutter.

[0024] Furthermore, the cooling mechanism includes cooling plates that are distributed at intervals and correspond to the first circular blade and the second circular blade, a cooling cavity is formed in the cooling plate, the opening of the cooling cavity is opposite to the first circular blade and the second circular blade, the parts of the first circular blade and the second circular blade close to the cooling cavity extend into the cooling cavity, and the cooling cavity is connected to a ventilation cooling duct to the outside.

[0025] Furthermore, the cooling plate is fixedly sleeved on the branch pipe, both ends of the branch pipe are fixedly passed through the side plate of the frame, and the branch pipe is provided with a small hole for connecting with the cooling cavity.

[0026] With the above technical solution, during the cutting process, the friction between the first circular blade, the second circular blade and the sponge will generate a large amount of heat. If the heat cannot be dissipated in time, the temperature of the blade will rise, which will affect its hardness and sharpness, and even cause the blade to deform or damage. The cooling mechanism directly cools the blade through the cooling cavity in the cooling plate, effectively reducing the temperature of the first circular blade and the second circular blade, thereby extending the service life of the first circular blade and the second circular blade.

[0027] The beneficial effects of the present invention are as follows: the present invention uses the first cutter and the second cutter to perform non-penetrating cutting from the upper and lower surfaces of the sponge respectively, and the non-penetrating cutting retains part of the connection at the sponge cutting seam, that is, a breakable connection is formed at the cutting seam. This connection method can maintain the integrity of the sponge during transportation, prevent the sponge from scattering due to complete cutting, and help reduce damage to the sponge during transportation and subsequent processing, thereby improving the finished granulation effect. In addition, the downwardly inclined separation belt design allows the sponge to be naturally pressed and separated during transportation, that is, the breakable connection is disconnected and the separation into particles is completed, avoiding the sponge from being cut multiple times to form irregular particles, so that the final sponge particle shape is more regular and consistent.

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0043] Any number of elements in the drawings is for illustration and not limitation, and any naming is for distinction only and does not have any limiting meaning.

[0044] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0045] Embodiments of the sponge crusher provided by the present invention:

[0046] like Figures 1 to 11 As shown, it includes a frame 1, a conveying mechanism 2, a cutter assembly 3, a dividing mechanism 4, a reciprocating cutter mechanism 5 and a cooling mechanism 6.

[0047] The conveying mechanism 2 is arranged on the frame 1 and is used to convey the sponge. The conveying mechanism 2 specifically includes a conveyor belt and a driving roller for driving the conveyor belt to convey. The whole sponge to be cut is placed on the conveyor belt, and the sponge is conveyed forward to the cutter assembly 3 through the conveyor belt.

[0048] The cutter assembly 3 is arranged at the output end of the conveying mechanism 2, and the cutter assembly 3 includes a first cutter 31 and a second cutter 32. The first cutter 31 and the second cutter 32 are respectively distributed on the upper side and the lower side of the sponge. When the first cutter 31 and the second cutter 32 cut from the upper surface and the lower surface of the sponge respectively, non-penetrating cutting seams are formed on the upper surface and the lower surface of the sponge, and the cutting seams on the upper surface and the cutting seams on the lower surface of the sponge are relatively distributed.

[0049] The first cutter 31 comprises a first rotating shaft 311 rotatably supported by the frame 1, and the first rotating shaft 311 is fixedly sleeved with first circular blades 312 distributed at intervals; the second cutter 32 comprises a second rotating shaft 321 rotatably supported by the frame 1, and the second rotating shaft 321 is fixedly sleeved with second circular blades 322 distributed at intervals.

[0050] The first circular blade 312 thereon is driven to rotate by the rotation of the first rotating shaft 311 , and the second circular blade 322 thereon is driven to rotate by the rotation of the second rotating shaft 321 .

[0051] The first cutter 31 and the second cutter 32 are spaced apart along the conveying direction of the sponge, so that there is a spacing between the first circular blade 312 and the second circular blade 322 in the horizontal direction, and the vertical spacing between the first circular blade 312 and the second circular blade 322 is 3 mm. Of course, in other embodiments, the vertical spacing between the first circular blade 312 and the second circular blade 322 can also be any value between 3 mm and 5 mm. A limit plate is fixedly provided on the frame 1, which is opposite to the second cutter 32 in the air. A second conveying roller rotatably supported by the frame 1 is provided on the side of the limit plate close to the first cutter 31. A first conveying roller located above the conveying mechanism 2 is provided on the side of the first cutter 31 away from the second cutter 32. The sponge conveyed by the conveying mechanism 2 first passes between the conveying mechanism 2 and the first conveying roller and is then transported to the first cutter 31. The sponge is cut on the upper surface by the first circular blade 312 on the first cutter 31, then passes between the two second conveying rollers, then goes between the second cutter 32 and the limit plate, and then passes through the second circular blade 322 on the second cutter 32 to cut the sponge on the lower surface.

[0052] The first circular blade 312 and the second circular blade 322 are used to perform non-through cutting from the upper and lower surfaces of the sponge respectively, forming relatively distributed cutting seams, so that a 3 mm breakable connection is formed between the upper and lower cutting seams, avoiding shape deviation that may be caused by complete cutting at one time, and providing a good foundation for subsequent sponge segmentation, so that the final sponge particle shape is more regular and consistent.

[0053] The non-penetrating cutting retains the partial connection at the sponge cutting seam, that is, a breakable connection is formed at the cutting seam. This connection method can maintain the integrity of the sponge during transportation and prevent the sponge from scattering due to complete cutting. It helps to reduce damage to the sponge during transportation and subsequent processing and improve the finished granulation effect.

[0054] In addition, the first circular blade 312 and the second circular blade 322 cut from the upper and lower surfaces respectively, which can significantly reduce the depth that a single blade needs to penetrate the sponge during each cutting. On the one hand, it improves the cutting effect, and on the other hand, it reduces the wear and heat accumulation of the first circular blade 312 and the second circular blade 322, thereby extending the service life of the blade.

[0055] In this embodiment, the frame 1 is fixed with cooling mechanisms 6 which are respectively located above the first cutter 31 and below the second cutter 32 .

[0056] Among them, the structures of the two cooling mechanisms 6 are the same. The cooling mechanism 6 includes cooling plates 61 that are distributed at intervals and correspond to the first circular blade 312 and the second circular blade 322. A cooling cavity 62 is formed in the cooling plate 61. The opening of the cooling cavity 62 is opposite to the first circular blade 312 and the second circular blade 322. The parts of the first circular blade 312 and the second circular blade 322 close to the cooling cavity 62 extend into the cooling cavity 62. The cooling cavity 62 is connected to the ventilation cooling duct to the outside.

[0057] The cooling plate 61 is vertically distributed one-to-one with the first circular blade 312 and the second circular blade 322. A cooling cavity 62 is formed in each cooling plate 61. A portion of the first circular blade 312 and the second circular blade 322 extends into the cooling cavity 62. The cooling cavity 62 contains cold air. By providing the cooling cavity 62, it is helpful to gather the cold air in the cooling cavity 62, so that the cold air resources can be used more effectively. The cold air can more evenly surround the portion where the first circular blade 312 and the second circular blade 322 extend in the cooling cavity 62, thereby achieving more comprehensive cooling of the first circular blade 312 and the second circular blade 322. Compared with direct spraying of cold air, direct spraying may cause uneven distribution of cold air, with some areas being over-cooled and some areas being under-cooled.

[0058] The cooling plate 61 is fixedly sleeved on the branch pipe 63 , and both ends of the branch pipe 63 are fixedly passed through the side plate of the frame 1 . The branch pipe 63 is provided with a small hole 631 for connecting with the cooling cavity 62 .

[0059] The branch pipe 63 is externally connected to a cooling fan. After the cold air enters the branch pipe 63, it enters the corresponding cooling cavity 62 through the small hole 631 to cool the first circular blade 312 and the second circular blade 322 extending into the interior thereof.

[0060] In this embodiment, the dividing mechanism 4 is arranged at one end of the cutter assembly 3 away from the conveying mechanism 2, and the dividing mechanism 4 includes a separating belt 41 for separating the connecting part at the sponge cutting seam, and the separating belt 41 is inclined downward from one end close to the cutter assembly 3 to the other end, and there are a plurality of separating belts 41 distributed at intervals, and supporting end plates 46 for assisting sponge separation are provided between adjacent separating belts 41.

[0061] Wherein, adjacent support end plates 46 are connected via connecting columns, and the side surfaces of the outermost support end plates 46 are fixedly connected to the side plates of the frame 1 via connecting columns.

[0062] The separation belt 41 is tilted downward, so that the vertical distance between the separation belt 41 and the support end plate 46 gradually decreases along the conveying direction of the sponge. The cutting seam formed after the sponge passes through the first cutter 31 and the second cutter 32 corresponds to the separation belt 41. The sponge on both sides of the cutting seam is supported by the support end plate 46. As the sponge is conveyed, the separation belt 41 will form a downward force at the cutting seam, so that a separation force is formed at the fragile connection of the cutting seam, and the fragile connection can be easily separated.

[0063] Among them, a pressure roller 42 for compressing the sponge downward is provided at one end of the separation belt 41 close to the cutter assembly 3, and an active roller 43 is provided at the other end of the separation belt 41. The pressure roller 42 and the active roller 43 are connected by the separation belt 41. The pressure roller 42 and the active roller 43 are both provided with an annular groove 421 for limiting the separation belt 41. A support plate 12 is fixedly provided on the frame 1 and is located below the pressure roller 42. The thickness of the sponge is compressed when it passes between the pressure roller 42 and the support plate 12.

[0064] The active roller 43 is driven by a motor fixed on the frame 1, and drives the separation belt 41 to transmit the transmission, while driving the pressure roller 42 to rotate. While the pressure roller 42 rotates, on the one hand, it vertically compresses the sponge to make the sponge thinner and easier to cut, and on the other hand, it assists in conveying the sponge forward.

[0065] Among them, a pressure plate 44 is provided on the side of the pressure roller 42 close to the active roller 43, and the two ends of the pressure plate 44 are correspondingly fixed on the frame 1, and the bottom end surface of the pressure plate 44 is flush with the bottom end of the pressure roller 42, and an auxiliary plate 441 is provided on the side of the pressure plate 44 close to the pressure roller 42, and the auxiliary plate 441 is relatively distributed with the annular groove 421, and the auxiliary plate 441 includes a horizontal plate 4411 and an arc plate 4412, and the arc plate 4412 is correspondingly clamped in the annular groove 421, and the outer surface of the arc plate 4412 facing away from the center of the pressure roller 42 is flush with the outer peripheral surface of the pressure roller 42.

[0066] The arc plate 4412 is fitted into the annular groove 421 so that the surface of the pressure roller 42 used to compress the sponge is flat, thereby making the sponge flatter during the compression process, reducing deformation of the sponge, and helping to improve the cutting effect.

[0067] A wedge plate 442 is provided on one side of the pressure plate 44 away from the pressure roller 42. The wedge plate 442 helps to extend the compression range of the sponge laterally while avoiding interference with the separation belt 41, so that the separation belt 41 can more easily act on the sponge cutting seam, making it easier to disconnect the fragile connection at the sponge cutting seam.

[0068] Among them, a support shaft 45 is provided on the side of the active roller 43 close to the pressure roller 42, and the support shaft 45 is located above the lower separation belt 41. A plurality of groups of guide plates 451 are fixedly sleeved on the support shaft 45, and each group of guide plates 451 is symmetrically distributed with two guide plates 451, and the two guide plates 451 are separated on both sides of the separation belt 41.

[0069] The baffle plate 451 is provided to prevent the cut sponge from entering the active roller 43 along the lower separation belt 41 due to static electricity and other reasons, thereby causing equipment failure, thereby reducing downtime caused by equipment failure and improving production efficiency.

[0070] The reciprocating cutter mechanism 5 is arranged below the end of the dividing mechanism 4 close to the cutter assembly 3 and is used to cut the sponge, and the cutting direction of the reciprocating cutter mechanism 5 is perpendicular to the cutting direction of the cutter assembly 3. The reciprocating cutter mechanism 5 is used to cut the sponge after the thickness is compressed.

[0071] Among them, the reciprocating cutting mechanism 5 includes a cutting plate 51 corresponding to the bottom of the pressure plate 44 and a telescopic member 52 fixed under the support plate 12 and driving the cutting plate 51 to move up and down, the top edge of the cutting plate 51 is a cutting edge, the support plate 12 and the support end plate 46 are laterally spaced apart and a guide groove 121 is formed between the support plate 12 and the support end plate 46 to allow the cutting plate 51 to pass vertically.

[0072] The telescopic member 52 is specifically a cylinder, which drives the blade 51 to move vertically by telescoping. The length direction of the blade 51 is parallel to the axial direction of the first rotating shaft 311 and the second rotating shaft 321. The lower end surface of the pressing plate 44 is formed with an avoidance groove 443 opposite to the blade 51.

[0073] The knife plate 51 is vertically opposite to the pressing plate 44 and is provided with an avoidance groove 443, which ensures the cutting effect while preventing the knife plate 51 from vertically penetrating through the sponge to cut the sponge and affecting the safety of use.

[0074] When the sponge crusher of this embodiment is used, the whole piece of sponge to be cut is placed on the conveying mechanism 2 and conveyed in the direction of the cutting knife assembly 3. It is first cut by the upper surface of the sponge by the first cutting knife 31, and then conveyed to the second cutting knife 32 to be cut by the lower surface of the sponge. After cutting by the first cutting knife 31 and the second cutting knife 32, a plurality of spaced cutting seams are formed on the sponge, and a 3mm fragile connection is formed between the two vertically opposite cutting seams. At this time, the sponge is still conveyed forward as a whole and reaches the top of the support plate 12. Then it only needs to be conveyed to the bottom of the pressure roller 42. The pressure roller 42 assists the sponge in conveying forward and compresses the sponge vertically at the same time, so that the thickness of the sponge becomes thinner. When the sponge with compressed thickness passes through the reciprocating cutting knife mechanism 5, the knife plate 51 moves vertically to penetrate the cutting sponge, so that the sponge forms a strip with a cutting seam. The long strip of sponge continues to be conveyed through the separation belt 41, so that the fragile connection part at the cutting seam is separated, and the regular granulation of the sponge is completed.

[0075] During specific use, cold air can be introduced into the branch pipe 63 to cool the first circular blade 312 and the second circular blade 322 to extend the service life of the first circular blade 312 and the second circular blade 322 .

Therefore, the above-mentioned orientation or positional relationship terms cannot be understood or interpreted as limitations on the scheme of the present invention.
