Description

Technical Field

[0002] When processing plastics, a pelletizing device is needed to cut the plastic extruded by the extruder into particles of suitable size. The main purpose of plastic pelletizing is to facilitate reuse and recycling. After the waste plastics are processed into pellets, they are smaller in size and lighter in weight, so they are easier to transport and store.

[0003] When pelletizing plastic, the existing pelletizing device generally uses the rotation or movement of the cutter to cut the extruded plastic. However, in actual use, since the temperature of the extruded plastic is high and has a certain viscosity, the cutter directly cuts it immediately afterwards, and the cut plastic particles are easy to adhere to the surface of the cutter, affecting the subsequent pelletizing operation of the cutter. At the same time, the newly extruded plastic is at a high temperature and has a soft texture. If the cutter cuts it directly, it is easy to deform, resulting in uneven plastic particles, which affects the granulation effect.

DETAILED DESCRIPTION

[0030] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0031] The present invention provides the following preferred embodiments: Embodiment 1, as Figure 1-Figure 9 As shown, a material cutting device for anti-sticking plastic processing includes a collecting box 13, a frame 12 is installed on one side of the collecting box 13, and an extrusion die head 11 is provided on the surface of the frame 12 close to the collecting box 13. Specifically, 12 is a plastic extruder, and the main machine of the plastic extruder is an extruder, which is composed of an extrusion system, a transmission system and a heating and cooling system. When working, the plastic is extruded through 11, and then the extruded plastic is cut to complete the pelletizing of the plastic. 12 is a prior art and will not be specifically described here, and also includes a pelletizing mechanism, a knocking mechanism and an anti-deformation mechanism; The pelletizing mechanism includes a first mounting plate 20, a cutter 21, a lifting assembly and two second mounting plates 14. The two second mounting plates 14 are symmetrically arranged on both sides of the extrusion die 11 and fixedly mounted on the frame 12. The first mounting plate 20 is located between the two second mounting plates 14. The cutter 21 is fixedly mounted at the bottom end of the first mounting plate 20. The lifting assembly is located between the first mounting plate 20 and the two second mounting plates 14. The lifting assembly is used to drive the first mounting plate 20 to rise and fall, thereby realizing the lifting and falling of the cutter 21, and pelletizing the plastic extruded by the extrusion die 11. The knocking mechanism includes a top plate 30, a knocking block 59, a swinging assembly, a buffer assembly, a rotating assembly and a transmission assembly. The knocking block 59 is located on one side of the first mounting plate 20 close to the frame 12. The top plate 30 is fixedly mounted on the top of one of the second mounting plates 14. The swinging assembly is mounted on the top plate 30, and one end is connected to the knocking block 59. The swinging assembly is used to drive the knocking block 59 to swing. The knocking block 59 contacts the first mounting plate 20 during the swinging process, thereby knocking the first mounting plate 20, so that the cutter 21 below the first mounting plate 20 can vibrate to achieve the effect of shaking off the adhered particles. The buffer assembly is located on one side of the swinging assembly. The buffer assembly can buffer the swinging of the knocking block 59, and is also conducive to the rapid resetting of the knocking block 59. The rotating assembly is mounted below the swinging assembly, and the transmission assembly is located between the rotating assembly and the lifting assembly. The knocking block 59 is designed in the present application to reduce the possibility of plastic particles adhering to the cutter 21. Since the long plastic segment is formed into plastic particles after cutting, the volume is small. With the previous preliminary cooling, even if the plastic particles adhere to the cutter 21, the adhesion force is relatively small. When hit by the knocking block 59, it is easy to fall off, which can achieve the effect of knocking off the plastic particles adhering to the cutter 21. Preferably, the knocking block 59 is made of rubber material.

[0032] The anti-deformation mechanism includes a support plate 49, a rotating plate 52 and a flip assembly. The support plate 49 is located on one side of the extrusion die 11. The rotating plate 52 is fixedly mounted on the bottom end of one side of the support plate 49 close to the extrusion die 11. The other end of the arc knife 51 rotates on the extrusion die 11. The flip assembly is located between the rotating plate 52 and the extrusion die 11. During the cutting process, the support plate 49 can be used to support the plastic to be cut, so that when the cutter 21 cuts the plastic, the support of the support plate 49 can reduce the deformation of the plastic particles during the cutting process, making the cut plastic particles more uniform.

[0033] like Figure 1-Figure 9As shown, the lifting assembly includes a first strip groove 17, a first electric push rod 18, a push plate 19, two guide rails 15 and two moving blocks 16, the two guide rails 15 are respectively installed on the side of the two second mounting plates 14 close to each other, each moving block 16 is slidably arranged inside a guide rail 15, and the first mounting plate 20 is fixedly installed between the two moving blocks 16. The sliding connection between the guide rail 15 and the moving block 16 can guide the first mounting plate 20 when the first mounting plate 20 is lifted or lowered. The first strip groove 17 is opened on one side of one of the second mounting plates 14, and the push plate 19 slides inside the first strip groove 17, and one end of the push plate 19 passes through the first strip groove 17 and is connected to a moving block 16, the first electric push rod 18 is fixed to one side of a second mounting plate 14, and the output end of the first electric push rod 18 is connected to the push plate 19; When pelletizing is required, the first electric push rod 18 is controlled to work, and the first electric push rod 18 can drive the push plate 19 to move inside the first strip groove 17, so as to drive the first mounting plate 20 to rise and fall through the moving block 16, and the first mounting plate 20 can drive the cutter 21 to rise and fall. When the cutter 21 moves downward, the plastic at the extrusion die head 11 can be pelletized, and when the cutter 21 moves upward, it can prepare for the next pelletizing.

[0034] like Figure 1-Figure 9 As shown, the transmission assembly includes a connecting plate 22, a first docking block 23, a second docking block 24, a slide groove 25, a rack 26, an L-shaped vertical plate 27, a guide rod 28 and a first spring 29; The slide groove 25 is opened on one side of a second mounting plate 14, the rack 26 is slidably arranged inside the slide groove 25, the first docking block 23 is fixed to the bottom end of the rack 26, one end of the connecting plate 22 is connected to the first mounting plate 20, the second docking block 24 is fixed to the top of the other end of the connecting plate 22, the bottom end of the first docking block 23 and the top end of the second docking block 24 are abutted, the L-shaped vertical plate 27 is fixed to the top end of the second mounting plate 14, the guide rod 28 is slidably arranged on the L-shaped vertical plate 27, and the bottom end of the guide rod 28 is fixedly connected to the top end of the rack 26, the first spring 29 is sleeved on the guide rod 28, and the two ends of the first spring 29 are respectively connected to the L-shaped vertical plate 27 and the rack 26; During the upward movement of the first mounting plate 20, the second docking block 24 can be driven to move through the connecting plate 22. When the second docking block 24 contacts the first docking block 23, as the first mounting plate 20 continues to move upward, the first docking block 23 can be pushed to move upward, so that the rack 26 can slide inside the slide groove 25, the guide rod 28 slides on the L-shaped vertical plate 27, and the first spring 29 is compressed.

[0035] like Figure 1-Figure 9As shown, the rotating assembly includes a side plate 31, a spur gear 32, a first bevel gear 33, a second bevel gear 34, a driving wheel 35, a driven wheel 36 and a transmission belt 37; The side plate 31 is fixedly mounted on the bottom end of the top plate 30, the spur gear 32 is rotatably mounted on the side plate 31, the spur gear 32 is meshed with the rack 26, the driving wheel 35 and the driven wheel 36 are both rotatably mounted on the bottom end of the top plate 30, the transmission belt 37 is sleeved on the driving wheel 35 and the driven wheel 36, the second bevel gear 34 is fixed to one side of the driving wheel 35 and is coaxially arranged with the driving wheel 35, the first bevel gear 33 is fixed to one side of the spur gear 32 and is coaxially arranged with the spur gear 32, and the second bevel gear 34 and the first bevel gear 33 are meshed with each other; When the rack 26 moves upward, the rack 26 can drive the spur gear 32 to rotate, and the spur gear 32 drives the first bevel gear 33 to rotate. The first bevel gear 33 and the second bevel gear 34 are meshed with each other. Therefore, when the first bevel gear 33 rotates, it can drive the second bevel gear 34 to rotate, and the second bevel gear 34 drives the driving wheel 35 to rotate. Under the action of the transmission belt 37, the driven wheel 36 can rotate.

[0036] like Figure 1-Figure 9 As shown, the swing assembly includes a rotating rod 38, a roller 39, a swing rod 40, a knocking rod 41 and a lever 42, one end of the swing rod 40 rotates on the top plate 30, the other end of the swing rod 40 is connected to one end of the knocking rod 41, the other end of the knocking rod 41 is connected to the knocking block 59, the roller 39 is rotatably set at one end of the rotating rod 38, the rotating shaft of the driven wheel 36 passes through the top plate 30 and is fixedly connected to the other end of the rotating rod 38, and the lever 42 is fixed to a side of the swing rod 40 close to the roller 39; When the driven wheel 36 rotates, the rotating rod 38 can be driven to rotate, and the rotating rod 38 can drive the roller 39 to rotate. The roller 39 will interfere with the lever 42 during the rotation process. The interference force between the roller 39 and the lever 42 can drive the swing rod 40 to swing along the hinge point at one end thereof toward the side away from the first mounting plate 20, so that the swing rod 40 can drive the knocking rod 41 and the knocking block 59 to swing toward the side away from the first mounting plate 20. Through the transmission assembly, the operation of the swing assembly can be realized while the lifting assembly is working, so that the pelletizing mechanism and the knocking mechanism can achieve a linkage effect, that is, the operation of the two mechanisms can be realized by only using a first electric push rod 18, and there is no need to install a driving source on each mechanism, which is beneficial to reducing the number of driving sources used in the device, reducing power consumption, and thus helping to reduce costs.

[0037] like Figure 1-Figure 9As shown, the buffer assembly includes a first hinge block 43, a second hinge block 44, a telescopic rod 45 and a second spring 46. One end of the telescopic rod 45 is hinged to the swing rod 40 through the first hinge block 43, and the other end of the telescopic rod 45 is hinged to the top plate 30 through the second hinge block 44. The second spring 46 is sleeved on the outside of the telescopic rod 45, and the two ends of the second spring 46 are respectively connected to the second hinge block 44 and the first hinge block 43. When the swing arm 40 swings toward the side away from the first mounting plate 20, the second spring 46 is compressed. When the roller 39 rotates to no longer contact the lever 42, the second spring 46 can drive the swing arm 40 to swing in the opposite direction, thereby driving the knocking block 59 to swing toward the side close to the first mounting plate 20, thereby achieving a knock on the first mounting plate 20. That is, each time the cutter 21 completes a cut and moves to the top, the knocking block 59 can knock on the first mounting plate 20, so that the cutter 21 under the first mounting plate 20 can vibrate and shake off the adhered particles, thereby preventing the plastic particles from adhering to the cutter 21, so that when the cutter 21 moves downward for cutting next time, the plastic particles will not adhere to the cutter 21, and will not affect the next pelletizing effect.

[0038] like Figure 1-Figure 9 As shown, an arc guide rail 48 is fixed to one side of the top plate 30, and a moving rod 47 is inserted into the interior of the arc guide rail 48. The top end of the moving rod 47 is connected to the rocker arm 40. When the rocker arm 40 swings, the moving rod 47 can be driven to slide inside the arc guide rail 48. The sliding connection between the arc guide rail 48 and the moving rod 47 can guide the rocker arm 40 when it swings, thereby ensuring the stability of the rocker arm 40.

[0039] like Figure 1-Figure 9 As shown, the flip assembly includes a pusher, two mounting seats 53, two side rods 54, two second strip grooves 55 and two insertion rods 56. The two mounting seats 53 are symmetrically fixed on both sides of the extrusion die 11. The end of the rotating plate 52 away from the support plate 49 is rotatably set on the two mounting seats 53 through a rotating shaft. The two side rods 54 are symmetrically fixed on the surface of the rotating plate 52. Each second strip groove 55 is opened on a side rod 54, and each insertion rod 56 is inserted into the inside of a second strip groove 55.

[0040] like Figure 1-Figure 9 As shown, the push member includes a moving frame 57 and a second electric push rod 58, the second electric push rod 58 is fixedly mounted on the bottom end of the extrusion die 11, the two plug rods 56 are fixed on the moving frame 57, and the output end of the second electric push rod 58 is connected to the moving frame 57; When the plastic particles on the support plate 49 need to fall, the second electric push rod 58 is controlled to work, and the second electric push rod 58 drives the moving frame 57 to move toward the direction close to the second electric push rod 58, and the moving frame 57 can drive the two plug rods 56 to move, and under the action of the two plug rods 56, the rotating plate 52 can be driven to rotate along its rotating axis, so that the support plate 49 can be turned toward the side away from the extrusion die 11. When the support plate 49 is turned over, the plastic particles on the support plate 49 can be thrown out to the inside of the collection box 13, and the unloading is completed; Then, the second electric push rod 58 is used to drive the moving frame 57 to move in the reverse direction so that the supporting plate 49 can rotate in the reverse direction to prepare for the next pelletizing.

[0041] like Figure 1-Figure 9 As shown, a plurality of limiting grooves 50 are provided at the top of the support plate 49, and a plurality of arc-shaped knives 51 matching with the limiting grooves 50 are integrally formed at the bottom end of the cutter 21. The limiting grooves 50 can limit the extruded plastic, which is more conducive to reducing the deformation of plastic particles due to extrusion when the plastic is cut.

[0042] The specific working process of the present invention is as follows: The first electric push rod 18 is controlled to work. The first electric push rod 18 can drive the push plate 19 to move inside the first strip groove 17, so that the first mounting plate 20 can be driven to move up and down through the moving block 16. The first mounting plate 20 can drive the cutter 21 to move up and down. When the cutter 21 moves downward, the plastic at the extrusion die head 11 can be pelletized. After the cutting is completed, the first electric push rod 18 is used to drive the cutter 21 to move upward to prepare for the next pelletizing. In the process of the first mounting plate 20 moving upward, the second docking block 24 can be driven to move through the connecting plate 22. When the second docking block 24 contacts the first docking block 23, as the first mounting plate 20 continues to move upward, the first docking block 23 can be pushed to move upward, so that the rack 26 can slide inside the slide groove 25, the guide rod 28 slides on the L-shaped vertical plate 27, and the first spring 29 is compressed. When the rack 26 moves upward, the rack 26 can drive the spur gear 32 to rotate, and the spur gear 32 drives the spur gear 32 to rotate. The first bevel gear 33 is driven to rotate, and the first bevel gear 33 and the second bevel gear 34 are meshed with each other. Therefore, when the first bevel gear 33 rotates, the second bevel gear 34 can be driven to rotate, and the second bevel gear 34 drives the driving wheel 35 to rotate. Under the action of the transmission belt 37, the driven wheel 36 can be rotated. When the driven wheel 36 rotates, the rotating rod 38 can be driven to rotate. The rotating rod 38 can drive the roller 39 to rotate. The roller 39 will conflict with the lever 42 during the rotation process. The roller 39 and the lever 42 The resistance force between the two can drive the swing rod 40 to swing along the hinge point at one end thereof toward the side away from the first mounting plate 20, so that the swing rod 40 can drive the knocking rod 41 and the knocking block 59 to swing toward the side away from the first mounting plate 20. When the swing rod 40 swings toward the side away from the first mounting plate 20, the second spring 46 is compressed. When the roller 39 rotates to no longer contact the lever 42, the second spring 46 can drive the swing rod 40 to swing in the opposite direction, so that the knocking block 59 can be driven toward the side close to the first mounting plate 20. 0 swings on one side to achieve a knock on the first mounting plate 20, that is, each time the cutter 21 completes a cut and moves to the top, the knocking block 59 can knock on the first mounting plate 20, so that the cutter 21 below the first mounting plate 20 can vibrate and shake off the adhered particles, thereby achieving the effect of preventing the plastic particles from adhering to the cutter 21, so that when the cutter 21 moves downward for cutting next time, the cutter 21 will not adhere to the plastic particles, and will not affect the next pelletizing effect; After the cutter 21 completes a pelletizing operation, the second electric push rod 58 is controlled to work, and the second electric push rod 58 drives the movable frame 57 to move toward the direction close to the second electric push rod 58. The movable frame 57 can drive the two plug rods 56 to move, and the two plug rods 56 can drive the rotating plate 52 to rotate along its rotating axis, so that the support plate 49 can be flipped toward the side away from the extrusion die 11. When flipping, the support plate 49 can throw the plastic particles on the support plate 49 into the inside of the collecting box 13 to complete the unloading. Then, the second electric push rod 58 is used to drive the movable frame 57 to move in the opposite direction so that the support plate 49 can rotate in the opposite direction to prepare for the next pelletizing operation.
