Technical Field
[0001] The present invention belongs to the technical field of cutting machines, and specifically relates to a masterbatch cutting machine. Background Art
[0002] Masterbatch is a special colorant for new polymer materials, mainly used in plastics. Masterbatch consists of three basic elements: pigments or dyes, carriers, and additives. It is an aggregate obtained by uniformly loading an excessive amount of pigments onto resin, and can be called pigment concentrate. Therefore, its coloring power is higher than that of the pigment itself. During processing, a small amount of masterbatch is admixed with uncolored resin to achieve the colored resin or product with the designed pigment concentration. It is mainly used in plastics. During processing, a small amount of masterbatch is admixed with uncolored resin to achieve the colored resin or product with the designed pigment concentration. When masterbatch is first produced, it is in strip shape and needs to be cut into granular form for convenient packaging and use.
[0003] When the existing masterbatch cutting machine deeply cuts the masterbatch strip, due to the relatively large and difficult-to-control pressure of the cutting machine, the cut masterbatch particles will adhere to the cutting surface under the action of the extrusion force. After the cutting surface adheres to the masterbatch particles, its sharpness will drop significantly, seriously affecting the subsequent cutting work. Summary of the Invention
[0004] (I) Technical Problems to be Solved Aiming at the deficiencies of the prior art, the present invention provides a masterbatch cutting machine, which solves the problem that the cut masterbatch particles will adhere to the cutting surface under the action of the extrusion force, and after the cutting surface adheres to the masterbatch particles, its sharpness will drop significantly, seriously affecting the subsequent cutting work.
[0005] (II) Technical Solutions The technical solution adopted by the present invention to solve its technical problems is as follows: A masterbatch cutting machine described in the present invention includes side plates, and upper and lower sides of the outer surface of the side plates are symmetrically provided with surrounding shells. A cutting device is arranged inside the surrounding shells, and a through hole is opened in the middle of the inner wall of the surrounding shells. When using this device to cut the masterbatch strip, the device is in the Figure 1 shown state. The masterbatch strip is passed through the side openings on both sides of the surrounding shell until the part of the masterbatch strip to be cut is completely inserted into the inside of the surrounding shell, and the feeding work is prepared.
[0006] Preferably, the cutting device includes a bottom air box. On one side of the inner cavity of the bottom air box away from the inner wall of the surrounding housing, a connecting sliding cylinder is fixedly connected. One end of the connecting sliding cylinder away from the bottom air box is fixedly connected with a power device. On the left and right sides of the outer surface of the connecting sliding cylinder, composite cutting plates are symmetrically arranged. One end of the power device away from the connecting sliding cylinder is fixedly connected with a fixed housing sleeve. On the upper surface of the fixed housing sleeve, buffer sliding rods are evenly arranged. A buffer spring is sleeved on the outer surface of the buffer sliding rods. A modified plate is slidably connected to the inner wall of the fixed housing sleeve. On one side of the inner cavity of the modified plate away from the connecting sliding cylinder, articulated cutting knives are evenly arranged. When cutting the color masterbatch strip, the rotating motors on both sides rotate simultaneously. After the rotating motor below rotates the strip-shaped push rod, the strip-shaped push rod moves to Figure 4 the state shown. Since the rotating motor is fixedly connected to the outer surface of the side plate, the rotating motor will not move. The strip-shaped push rod pushes the piston cylinder upward. Because during the mutual extrusion of the two fixed housing sleeves, the buffer sliding rods on the upper and lower sides will first come into contact and be squeezed. At this time, the buffer spring is compressed and shortened to play a buffering role, preventing the problem that the impact force generated by the mutual collision of the fixed housing sleeves is too large and causing damage during long-term use.
[0007] Preferably, the power device includes a piston cylinder. On the front and rear sides of the inner wall of the piston cylinder, vertical cutting grooves are symmetrically opened. The inner wall of the piston cylinder is rotationally connected with a strip-shaped push rod through the vertical cutting grooves. At the center of the strip-shaped push rod, a rotating motor is fixedly connected through a connecting rod. During the upward sliding of the piston cylinder, the piston cylinder first slides upward along the inner wall of the hollow connecting sleeve. At this time, the top of the piston cylinder pushes upward against the upper part of the inner wall of the extrusion slide plate, thereby pushing the extrusion slide plate upward. The extrusion slide plate slides upward along the inner wall of the fixed housing sleeve. When the extrusion slide plate slides up to the uppermost part of the inner wall of the fixed housing sleeve, the side ventilation openings of the extrusion slide plate and the side ventilation openings of the fixed housing sleeve are staggered with each other. Blocked by the inner wall of the fixed housing sleeve, the side ventilation openings of the extrusion slide plate are closed. Subsequently, the entire fixed housing sleeve slides upward. The upper fixed housing sleeve and the lower fixed housing sleeve move in opposite directions, so the two fixed housing sleeves clamp each other. The articulated cutting knives segment and then crush the middle color masterbatch strip into color masterbatch particles. When this device extrudes and cuts the color masterbatch strip, it can not only cut through the extrusion force, but also the pressure of the air pressure on both sides can further increase the shear stress of the extrusion of the articulated cutting knives, making the cutting effect better and preventing the situation that the extrusion speed of the piston cylinder is slow and the extrusion force becomes smaller, resulting in the color masterbatch strip not being completely cut off.
[0008] Preferably, the modified plate includes a hollow connecting sleeve. On the outer surface of the hollow connecting sleeve, an extrusion slide plate is fixedly connected. On one side of the outer surface of the extrusion slide plate away from the hollow connecting sleeve, strip-shaped sockets are evenly opened. On the side surface of the inner wall of the extrusion slide plate, side ventilation openings are evenly arranged.
[0009] Preferably, the inner wall of the hollow connecting sleeve is slidably connected to the upper part of the outer surface of the piston cylinder. The outer surface of the extrusion slide plate is slidably connected to the inner wall of the fixed casing sleeve. The inner wall of the extrusion slide plate is fixedly connected to the bottom end of the articulated cutting knife through a strip-shaped socket. The number of buffer slide rods is eight, the number of bottom air boxes is two, the number of composite cutting plates is four, and the number of rotating motors is four. When the device cuts the color masterbatch strip, the cutting surface of the fixed casing sleeve can generate wind force on one side of the color masterbatch strip particles. Therefore, it is relatively difficult for the cut color masterbatch strip particles to adhere to the outer surface of the articulated cutting knife, thus ensuring the sharpness of the articulated cutting knife during continuous operation.
[0010] Preferably, side ventilation openings are evenly formed on the side surface of the inner wall of the fixed casing sleeve, and the side ventilation openings of the fixed casing sleeve and the side ventilation openings of the extrusion slide plate have the same diameter. During the cutting process, the bottom air box continuously blows air to the modified plate through the power device. The cut color masterbatch particles are separated from the outer surface of the articulated cutting knife as the cutting device moves continuously and are blown out from the side openings of the outer shell on both sides under the action of the wind force on both sides.
[0011] Preferably, the side of the outer surface of the rotating motor away from the output shaft is fixedly connected to the outer surface of the side plate. The outer surface of the strip-shaped push rod is slidably connected to the inner wall of the piston cylinder. The vertical cutting groove is fixedly connected to the upper and lower sides of the outer surface of the connecting rod through a side spring belt. When the rotating motor rotates to Figure 3 the state shown, the lower extrusion slide plate loses the thrust of the piston cylinder and slides down under the action of gravity. At this time, the side ventilation opening of the extrusion slide plate is connected to the side ventilation opening of the fixed casing sleeve, and the air blown by the bottom air box will be blown out through the side ventilation opening of the fixed casing sleeve. At this time, there is no wind force acting on the upper part of the fixed casing sleeve.
[0012] Preferably, the articulated cutting knife includes a pointed outer shell. A bundled sliding shell is slidably connected to the middle of the inner wall of the pointed outer shell. The top of the bundled sliding shell is evenly provided with movable hollow strips. Connecting springs are symmetrically arranged on the left and right sides of the upper surface of the bundled sliding shell. Side cutting grooves are evenly formed on the upper part of the inner wall of the movable hollow strips.
[0013] Preferably, the outer surface of the bundled sliding shell is slidably connected to the upper part of the inner wall of the pointed shell. The top of the inner wall of the bundled sliding shell is fixedly connected to the lower part of the outer surface of the movable hollow bar. The upper part of the outer surface of the movable hollow bar is slidably connected to the upper part of the inner wall of the pointed shell. When the bar-shaped socket above the sliding plate is squeezed to ventilate, the air flow pushes the movable hollow bar upward, the bundled sliding shell slides upward, and the top end of the movable hollow bar extends out of the pointed shell. At this time, the gas blows out to both sides from the side cutting groove, blowing off the color masterbatch particles adhered to the upper surface of the pointed shell. Subsequently, under the thrust of the connecting spring, the bundled sliding shell slides downward, and the movable hollow bar retracts into the interior of the pointed shell. Because the gas blows out to both sides from the side cutting groove, during the process of blowing air from the side cutting groove, the color masterbatch particles adhered to the outer surface of the pointed shell can be further blown off, and the blowing direction is along the cross-section of the pointed shell, so that the blown color masterbatch particles will not float up and fall back onto the outer surface of the pointed shell again.
[0014] Preferably, the composite cutting plate includes side sealing plates. The bottom of the inner cavity of the side sealing plates is fixedly connected with a counterweight block through a through groove. The lower part of the outer surface of the side sealing plates is evenly provided with biting teeth.
[0015] Preferably, one side of the outer surface of the side sealing plate is fixedly connected with the outer surface of the connecting sliding cylinder through a connecting plate. The other side of the outer surface of the side sealing plate is slidably connected with the outer surface of the surrounding shell.
[0016] Preferably, the outer surface of the bottom air box is fixedly connected with the inner wall of the surrounding shell through a through port. The inner cavity of the bottom air box is fixedly connected with an external power supply through a through port. During the process of the articulated cutting knife squeezing and cutting the color masterbatch strip, the two side sealing plates move closer together as the connecting sliding cylinder moves. Under the meshing action of the biting teeth, the end of the color masterbatch strip is bitten, and the openings on both sides of the surrounding shell are closed, preventing the problem that the color masterbatch strip is too long and unstable during cutting, and preventing the cut color masterbatch particles from being immediately blown out, resulting in waste of color masterbatch particles.
[0017] The beneficial effects of the present invention are as follows: 1. When the device squeezes and cuts the color masterbatch strip, not only can it cut through the extrusion force, but the air pressure on both sides can further increase the shear stress of the articulated cutting knife during extrusion, making the cutting effect better, and preventing the situation that the piston cylinder has a slow extrusion speed and a reduced extrusion force, resulting in the color masterbatch strip not being completely cut off.
[0018] 2. When the device cuts the color masterbatch strip, the cutting surface of the fixed shell sleeve can generate wind force on one side of the color masterbatch strip particles. Therefore, the cut color masterbatch strip particles are relatively difficult to adhere to the outer surface of the articulated cutting knife, thereby ensuring the sharpness of the articulated cutting knife during continuous operation.
[0019] 3. Because during the mutual extrusion of the fixed casings on both sides, the buffer sliding rods on the upper and lower sides will come into extrusion contact first. At this time, the buffer springs are compressed and shortened to play a buffering role, preventing the problem that the impact force generated by the mutual collision of the fixed casings is too large and causing damage during long-term use.
[0020] 4. Because the gas is blown out from the side grooves to both sides, during the blowing process in the side grooves, the color masterbatch adhering to the outer surface of the pointed housing can be further blown off, and the blowing direction is along the cross-section of the pointed housing, so that the blown color masterbatch will not float up and fall back onto the outer surface of the pointed housing again.
[0021] 5. During the process of the articulated cutting knife squeezing and cutting the color masterbatch strip, the side sealing plates on both sides move closer together as the connecting sliding cylinder moves. Under the meshing action of the toothed rack, the end of the color masterbatch strip is bitten, and the openings on both sides of the surrounding housing are closed, preventing the problem that the color masterbatch strip is too long and unstable and shakes during cutting, and preventing the cut color masterbatch from being immediately blown out, resulting in waste of color masterbatch.

DETAILED DESCRIPTION OF THE INVENTION
[0024] UseFigures 1-7 A color masterbatch cutting machine according to an embodiment of the present invention will be described as follows.
[0025] As Figures 1-7 shown, a color masterbatch cutting machine of the present invention includes side plates 1. On the upper and lower sides of the outer surface of the side plates 1, surrounding shells 2 are symmetrically arranged. A cutting device 4 is arranged inside the surrounding shells 2. A through hole 3 is opened in the middle of the inner wall of the surrounding shells 2. When using this device to cut the color masterbatch strip, the device is in the Figure 1 state shown. The color masterbatch strip is passed through the side openings on both sides of the surrounding shell 2 until the part of the color masterbatch strip to be cut is completely inserted into the inside of the surrounding shell 2, and the feeding work is prepared.
[0026] The cutting device 4 includes a bottom air box 41. On one side of the inner cavity of the bottom air box 41 away from the inner wall of the surrounding shell 2, a connecting sliding cylinder 42 is fixedly connected. One end of the connecting sliding cylinder 42 away from the bottom air box 41 is fixedly connected to a power device 5. On the left and right sides of the outer surface of the connecting sliding cylinder 42, composite cutting plates 8 are symmetrically arranged. One end of the power device 5 away from the connecting sliding cylinder 42 is fixedly connected to a fixed shell sleeve 43. Buffer sliding rods 45 are evenly arranged on the upper surface of the fixed shell sleeve 43. A buffer spring 44 is sleeved on the outer surface of the buffer sliding rods 45. A modified plate 6 is slidably connected to the inner wall of the fixed shell sleeve 43. On one side of the inner cavity of the modified plate 6 away from the connecting sliding cylinder 42, articulated cutting knives 7 are evenly arranged. When cutting the color masterbatch strip, the rotating motors 54 on both sides rotate simultaneously. After the lower rotating motor 54 rotates the strip-shaped push rod 53, the strip-shaped push rod 53 moves to the Figure 4 state shown. Since the rotating motor 54 is fixedly connected to the outer surface of the side plate 1, the rotating motor 54 will not move, and the strip-shaped push rod 53 pushes the piston cylinder 51 upward.
[0027] The power device 5 includes a piston cylinder 51. Vertically cutting grooves 52 are symmetrically formed on the front and rear sides of the inner wall of the piston cylinder 51. A strip-shaped push rod 53 is rotatably connected to the inner wall of the piston cylinder 51 through the vertically cutting grooves 52. A rotating motor 54 is fixedly connected to the axis of the strip-shaped push rod 53 through a connecting rod. During the upward sliding process of the piston cylinder 51, the piston cylinder 51 first slides upward along the inner wall of the hollow connecting sleeve 61. At this time, the top of the piston cylinder 51 upwardly pushes and presses the upper part of the inner wall of the extrusion slide plate 62, thereby upwardly pushing the extrusion slide plate 62. The extrusion slide plate 62 slides upward along the inner wall of the fixed housing sleeve 43. When the extrusion slide plate 62 slides up to the uppermost part of the inner wall of the fixed housing sleeve 43, the side ventilation openings 64 of the extrusion slide plate 62 and the side ventilation openings 64 of the fixed housing sleeve 43 are staggered with each other. Blocked by the inner wall of the fixed housing sleeve 43, the side ventilation openings 64 of the extrusion slide plate 62 are closed. Subsequently, the entire fixed housing sleeve 43 slides upward. The upper fixed housing sleeve 43 and the lower fixed housing sleeve 43 move in opposite directions, so the two fixed housing sleeves 43 on both sides are clamped to each other. The articulated cutting knife 7 segments and then crushes the middle masterbatch strip into masterbatch pellets.
[0028] The modified plate 6 includes a hollow connecting sleeve 61. An extrusion slide plate 62 is fixedly connected to the outer surface of the hollow connecting sleeve 61. Strip-shaped insertion openings 63 are uniformly formed on the side of the outer surface of the extrusion slide plate 62 away from the hollow connecting sleeve 61. Side ventilation openings 64 are uniformly formed on the side surface of the inner wall of the extrusion slide plate 62.
[0029] The inner wall of the hollow connecting sleeve 61 is slidably connected to the upper part of the outer surface of the piston cylinder 51. The outer surface of the extrusion slide plate 62 is slidably connected to the inner wall of the fixed housing sleeve 43. The inner wall of the extrusion slide plate 62 is fixedly connected to the bottom end of the articulated cutting knife 7 through the strip-shaped insertion openings 63. The number of buffer sliding rods 45 is eight. The number of bottom air boxes 41 is two. The number of composite cutting plates 8 is four. The number of rotating motors 54 is four.
[0030] Side ventilation openings 64 are uniformly formed on the side surface of the inner wall of the fixed housing sleeve 43, and the side ventilation openings 64 of the fixed housing sleeve 43 and the side ventilation openings 64 of the extrusion slide plate 62 have the same caliber. During the cutting process, the bottom air box 41 continuously blows air to the modified plate 6 through the power device 5. The cut masterbatch particles are separated from the outer surface of the articulated cutting knife 7 as the cutting device 4 continuously moves, and are blown out from the side openings of the outer shell 2 on both sides under the action of the wind on both sides.
[0031] The side of the outer surface of the rotating motor 54 away from the output shaft is fixedly connected to the outer surface of the side plate 1. The outer surface of the strip-shaped push rod 53 is slidably connected to the inner wall of the piston cylinder 51. The vertically cutting grooves 52 are fixedly connected to the upper and lower sides of the outer surface of the connecting rod through side spring bands. When the rotating motor 54 rotates to Figure 3In the shown state, the lower extrusion slide plate 62 loses the thrust of the piston cylinder 51 and slides down under the action of gravity. At this time, the side vent 64 of the extrusion slide plate 62 is connected to the side vent 64 of the fixed housing sleeve 43, and the air blown through the bottom air box 41 will be blown out through the side vent 64 of the fixed housing sleeve 43. At this time, there is no wind force acting on the upper part of the fixed housing sleeve 43.
[0032] The articulated cutting knife 7 includes a pointed outer shell 71. A bundled sliding shell 72 is slidably connected to the middle of the inner wall of the pointed outer shell 71. A plurality of movable hollow bars 74 are evenly arranged on the top of the bundled sliding shell 72. Connecting springs 73 are symmetrically arranged on the left and right sides of the upper surface of the bundled sliding shell 72. Side cutting grooves 75 are evenly formed in the upper part of the inner wall of the movable hollow bar 74.
[0033] The outer surface of the bundled sliding shell 72 is slidably connected to the upper part of the inner wall of the pointed outer shell 71. The top of the inner wall of the bundled sliding shell 72 is fixedly connected to the lower part of the outer surface of the movable hollow bar 74. The upper part of the outer surface of the movable hollow bar 74 is slidably connected to the upper part of the inner wall of the pointed outer shell 71. When the strip-shaped socket 63 above the extrusion slide plate 62 is ventilated, the air flow pushes the movable hollow bar 75 upward, the bundled sliding shell 72 slides upward, and the top end of the movable hollow bar 75 extends out of the pointed outer shell 71. At this time, the gas blows out to both sides from the side cutting grooves 75, blowing off the color masterbatch particles adhered to the upper surface of the pointed outer shell 71. Subsequently, under the thrust of the connecting spring 73, the bundled sliding shell 72 slides down, and the movable hollow bar 74 retracts into the interior of the pointed outer shell 71.
[0034] The composite cutting plate 8 includes side sealing plates 81. A counterweight block 82 is fixedly connected to the bottom of the inner cavity of the side sealing plates 81 through a through groove. Biting teeth 83 are evenly arranged on the lower part of the outer surface of the side sealing plates 81.
[0035] One side of the outer surface of the side sealing plate 81 is fixedly connected to the outer surface of the connecting sliding cylinder 42 through a connecting plate, and the other side of the outer surface of the side sealing plate 81 is slidably connected to the outer surface of the surrounding outer shell 2.
[0036] The outer surface of the bottom air box 41 is fixedly connected to the inner wall of the surrounding outer shell 2 through a through port 3. The inner cavity of the bottom air box 41 is fixedly connected to an external power supply through a through port 3. During the process of the articulated cutting knife 7 extruding and cutting the color masterbatch strip, the two side sealing plates 81 move closer together as the connecting sliding cylinder 42 moves. Under the meshing action of the biting teeth 83, the ends of the color masterbatch strip are bitten, and the openings on both sides of the surrounding outer shell 2 are closed, preventing the problem that the color masterbatch strip is too long and unstable during cutting and shaking.
[0037] The specific working process is as follows: When using this device to cut the color masterbatch strip, the device is in Figure 1In the state shown, pass the masterbatch strip through the side openings on both sides of the surrounding housing 2 until the part of the masterbatch strip to be cut is completely inserted into the interior of the surrounding housing 2, and prepare the feeding work.
[0038] When cutting the masterbatch strip, the rotating motors 54 on both sides rotate simultaneously. After the rotating motor 54 below rotates the strip-shaped push rod 53, the strip-shaped push rod 53 moves to Figure 4 the state shown. Since the rotating motor 54 is fixedly connected to the outer surface of the side plate 1, the rotating motor 54 does not move, and the strip-shaped push rod 53 pushes the piston cylinder 51 upward; during the upward sliding of the piston cylinder 51, the piston cylinder 51 first slides upward along the inner wall of the hollow connecting sleeve 61. At this time, the top of the piston cylinder 51 pushes upward against the upper part of the inner wall of the extrusion slide plate 62, and then pushes the extrusion slide plate 62 upward. The extrusion slide plate 62 slides upward along the inner wall of the fixed housing sleeve 43. When the extrusion slide plate 62 slides up to the uppermost part of the inner wall of the fixed housing sleeve 43, the side vent 64 of the extrusion slide plate 62 and the side vent 64 of the fixed housing sleeve 43 are staggered with each other. Blocked by the inner wall of the fixed housing sleeve 43, the side vent 64 of the extrusion slide plate 62 closes, and then the entire fixed housing sleeve 43 slides upward.
[0039] The upper fixed housing sleeve 43 and the lower fixed housing sleeve 43 move in opposite directions, so the fixed housing sleeves 43 on both sides clamp each other, and the articulated cutting knife 7 segments and then crushes the masterbatch strip in the middle into masterbatch pellets.
[0040] During this process, the bottom air box 41 continuously blows air to the modified plate 6 through the power device 5. The cut masterbatch particles break away from the outer surface of the articulated cutting knife 7 as the cutting device 4 continues to move, and are blown out from the side openings of the surrounding housing 2 on both sides under the action of the wind on both sides.
[0041] When the rotating motor 54 rotates to Figure 3 the state shown, the lower extrusion slide plate 62 loses the thrust of the piston cylinder 51 and slides down under the action of gravity. At this time, the side vent 64 of the extrusion slide plate 62 and the side vent 64 of the fixed housing sleeve 43 are connected to each other, and the air blown by the bottom air box 41 will be blown out through the side vent 64 of the fixed housing sleeve 43. At this time, there is no wind force acting on the upper part of the fixed housing sleeve 43.
[0042] When the strip-shaped socket 63 above the extrusion slide plate 62 is ventilated, the air flow pushes the movable hollow bar 75 upward, the beam sliding shell 72 slides up, and the top of the movable hollow bar 75 extends out of the pointed housing 71. At this time, the gas blows out from the side cutting groove 75 to both sides, blowing off the masterbatch particles adhering to the upper surface of the pointed housing 71. Then, under the thrust of the connecting spring 73, the beam sliding shell 72 slides down, and the movable hollow bar 74 retracts into the interior of the pointed housing 71.
[0043] During the process of the articulated cutter 7 extruding and cutting the masterbatch strip, the side sealing plates 81 on both sides move closer as the connecting sliding cylinder 42 moves. Under the meshing action of the toothed rack 83, the ends of the masterbatch strip are bitten, and the openings on both sides of the surrounding housing 2 are closed, preventing problems such as unstable shaking during cutting due to the long length of the masterbatch strip.
[0044] The embodiments of the present invention have been described above in conjunction with the accompanying drawings. However, the present invention is not limited to the above specific embodiments. The above specific embodiments are merely illustrative and not restrictive.
