DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0029] The present invention provides a plastic masterbatch continuous processing device, such as Figures 1 to 7As shown, it includes a base 1, an extruder is fixedly connected to the base 1 through a support frame, an extruder head 28 is provided on one side of the extruder, a melting device 2 for melting plastic is provided on one side of the base 1, a cooling pool 3 is provided on the right side of the base 1, a crusher 4 is provided on the right side of the cooling pool 3, guide rollers 5 are equidistantly provided inside the cooling pool 3, a bracket 6 is fixedly installed on the top of the guide roller 5 close to the extruder, a card slot is symmetrically provided on the top of the cooling pool 3, the bottom of the bracket 6 is located in the card slot, and the remaining guide rollers 5 are fixed on the inner wall of the cooling pool 3, a guide rail 7 is symmetrically provided inside the cooling pool 3, one end of the guide rail 7 is fixedly connected to the base 1, an opening is provided at the end of the guide rail 7 close to the base 1, a closing component for closing the opening is provided in the opening, and an inclined groove 29 is provided on the top of the base 1. The height of the bottom wall of the inclined groove 29 near the opening is lower than the height of the bottom wall of the inclined groove 29 far from the opening. An iron rod 8 is provided between the two guide rails 7 and on the top of the base 1. The guide rail 7 is provided with a driving component for driving the iron rod 8 to move along the guide rail 7. The end of the guide rail 7 near the base 1 is a horizontal section, and the part connected to the horizontal section is obliquely arranged until it extends into the cooling pool 3. Connected to the obliquely arranged part is another horizontal section, which is located below the guide roller 5. The part connected to the horizontal section is obliquely arranged and extends to the outside of the cooling pool 3. The end of the guide rail 7 away from the base 1 is not closed, and the magnet sheet 12 is located inside the guide rail 7. The width of the guide rail 7 is greater than the diameter of the iron rod 8. The iron rod 8 does not contact the top wall of the guide rail 7 when in the guide rail 7.

[0030] During use, the waste plastic is melted by the melting device 2, and then the melted waste plastic is introduced into the extruder, and then extruded through the extrusion head 28. After the extruded plastic leaves the extrusion head 28, it is in a vertical state under the action of gravity and becomes a plastic strip. At this time, the iron rod 8 is driven by the driving component to move along the guide rail 7. The iron rod 8 first moves along the horizontal section of the guide rail 7 to push the drooping plastic strip. After the plastic strip contacts the iron rod 8, it sticks to the surface of the iron rod 8, and then moves along the guide rail 7 into the cooling pool 3 with the plastic strip, enters the cooling water of the cooling pool 3, and then moves along another horizontal section of the guide rail 7 in the cooling water, and then moves along the guide rail 7 to the outside of the cooling pool 3 and leaves the cooling water. At this time, the staff can remove the iron rod 8 and hold the iron rod 8 with the plastic strip cooled by the cooling water. The plastic strip moves, and then the iron rod 8 is separated from the plastic strip by scissors, and the plastic strip is placed in the crusher 4 for crushing, so that the plastic strip is crushed into master batches. During the whole process, there is no need for the staff to hold the iron rod 8 close to the extrusion head 28 to perform the strip pulling operation. On the one hand, it can avoid the staff from being scalded by the extrusion head 28, and on the other hand, it makes the strip pulling operation easy. Then the driving component can be reset, and the closing component can cancel the closure of the opening. The iron rod 8 located in the inclined groove 29 moves along the inclined groove 29 to the driving component and is connected to the driving component. Then the closing component can be reset to close the opening. At this point, the resetting of the iron rod 8 is completed. If the plastic strip is disconnected during the strip pulling process, the iron rod 8 can be removed, and the new iron rod 8 can be connected to the driving component in the above manner, and the strip pulling operation of the plastic strip can be performed again.

[0031] like Figures 2 to 3 As shown, the driving assembly includes a vertical plate 9 symmetrically arranged in the cooling pool 3, the vertical plate 9 is fitted with the inner wall of the cooling pool 3, a vertical opening is opened on the vertical plate 9, a cross bar 10 is slidably installed in the vertical opening, a connecting plate 11 is provided at one end of the cross bar 10 close to the extruder, a magnet sheet 12 is fixedly installed on the inner side of the connecting plate 11, the magnet sheet 12 is arc-shaped, the magnet sheet 12 is adsorbed and fixed to the iron rod 8, and the end of the iron rod 8 is located in the guide rail 7, a horizontal opening is symmetrically opened on the outside of the cooling pool 3, a guide rod 14 is fixedly installed in the horizontal opening, a slider 13 is slidably sleeved on the guide rod 14, one end of the slider 13 is fixedly connected to the vertical plate 9, a first spring 15 is sleeved on the guide rod 14, and the first spring 15 is arranged on the side of the slider 13 away from the extruder, a motor 16 corresponding to the slider 13 is fixedly installed on the outside of the cooling pool 3, the output shaft of the motor 16 is fixedly connected to the winding wheel 17, and the winding wheel 17 and the slider 13 are fixedly connected by a pull rope 18.

[0032] The motor 16 is started to rotate its output shaft forward, thereby driving the winding wheel 17 to rotate, winding the pull rope 18, and then driving the slider 13 to move the vertical plate 9, the cross bar 10, the connecting plate 11, the magnet sheet 12 and the iron rod 8 in the direction away from the base 1. When the slider 13 moves, the first spring 15 is compressed to deform and generate a force, and as the iron rod 8 moves, it slides along the guide rail 7. When the iron rod 8 moves to the unclosed end of the guide rail 7, that is, it leaves the cooling pool 3 and leaves the coolant, the iron rod 8 can be pulled to move in the direction close to the top wall of the guide rail 7, that is, it moves in the direction close to the base 1, so that the iron rod 8 is separated from the magnet sheet 12 and the iron rod 8 can be removed. Then the motor 16 is started to reverse its output shaft, so that the pull rope 18 is released, and the first spring 15 releases the force to reset the slider 13, so that the vertical plate 9 moves and resets accordingly. In this process, the magnet sheet 12 moves along the guide rail 7 and is finally reset.

[0033] like Figure 2 As shown, the initial position of the iron rod 8 located in the guide rail 7 is between the extrusion head 28 and the extruder.

[0034] The iron rod 8 can push the plastic strip to move when it moves, and bring the plastic strip into the cooling water.

[0035] like Figure 1 As shown, the vertical plate 9 does not contact the bracket 6 when moving, and the two ends of the guide roller 5 connected to the bracket 6 are located between the two guide rails 7.

[0036] This enables the vertical plate 9 to perform normal horizontal movement.

[0037] like Figures 4 to 7 As shown, the closing component includes electric push rods 19 symmetrically fixedly mounted on one side of the base 1 close to the cooling pool 3, a lifting plate 20 is commonly fixedly mounted on the telescopic ends of the two electric push rods 19, a closing plate 21 is symmetrically fixedly mounted on the lifting plate 20, and a socket matching the closing plate 21 is provided at the bottom of the guide rail 7, and the closing plate 21 is inserted into the socket.

[0038] Start the electric push rod 19 to shorten it and bring the lifting plate 20 and the closing plate 21 down, so that the opening is opened. Conversely, start the electric push rod 19 to extend it, so that the closing plate 21 can be reset, thereby closing the opening.

[0039] like Figures 4 to 7 As shown, a movable groove is provided on the side of the connecting plate 11 close to the cross bar 10, and a baffle 22 is slidably installed in the movable groove. The baffle 22 is fixedly connected to the cross bar 10, and a second spring 23 is fixedly installed on the side of the baffle 22 close to the iron rod 8. The other end of the second spring 23 is fixed to the inner wall of the movable groove, and an extrusion component is provided at the bottom of the connecting plate 11 for driving it to move in a direction away from the iron rod 8.

[0040] When the magnet sheet 12 moves along the guide rail 7 in the cooling water, impurities will be attached to the contact surface between the magnet sheet 12 and the iron rod 8, affecting the subsequent adsorption and fixing effect of the iron rod 8. Therefore, during the resetting process of the magnet sheet 12, the extrusion assembly drives the connecting plate 11 to move it in the direction away from the iron rod 8. The second spring 23 is thereby compressed to deform and generate a force, and then the extrusion assembly cancels the drive to the connecting plate 11, and the second spring 23 releases the force to quickly reset the connecting plate 11 and the magnet sheet 12, so that the baffle 22 collides with the inner wall of the moving groove to generate vibration, and the vibration is transmitted to the magnet sheet 12, so that the impurities attached to the magnet sheet 12 are shaken off, so that the impurities are separated from the magnet sheet 12, and the magnet sheet 12 is cleaned, so that the subsequent magnet sheet 12 and the iron rod 8 can be stably adsorbed and fixed.

[0041] like Figures 4 to 7 As shown, the extrusion assembly includes a side plate 24 fixedly mounted on the bottom of the connecting plate 11, a baffle 25 is fixedly mounted on the side of the side plate 24 close to the iron rod 8, an extrusion rod 26 is rotatably mounted on the side of the side plate 24 close to the iron rod 8, the extrusion rod 26 is located between the baffle 25 and the vertical plate 9, the extrusion rod 26 is fitted with the baffle 25, an extrusion block 27 cooperating with the extrusion rod 26 is fixedly mounted on the outer side of the guide rail 7, and a curved surface is provided on the side of the extrusion block 27 close to the vertical plate 9.

[0042] When the connecting plate 11 moves in the direction away from the base 1, the side plate 24, the baffle 25 and the squeezing rod 26 move with it. When the squeezing rod 26 conflicts with the squeezing block 27, the squeezing rod 26 rotates to avoid the squeezing block 27. After the squeezing rod 26 leaves the squeezing block 27, under the action of gravity, the squeezing rod 26 rotates downward to reset. During the reset of the connecting plate 11, the squeezing rod 26 conflicts with the curved surface of the squeezing block 27. At this time, due to the existence of the baffle 25, the squeezing rod 26 cannot rotate and remains in a vertical state, thereby driving the side plate 24, the connecting plate 11, and the magnet sheet 12 along the curved surface to move in the direction away from the iron rod 8, compressing the second spring 23 to deform it and generate a force. When the squeezing rod 26 leaves the squeezing block 27, the second spring 23 releases the force and quickly resets the connecting plate 11 and the magnet sheet 12.

[0043] The method for processing using the above-mentioned plastic masterbatch continuous processing device comprises the following steps:

[0044] S1, when in use, the waste plastic is melted by the melting device 2, and then the melted waste plastic is introduced into the extruder, and then extruded through the extrusion head 28. After the extruded plastic leaves the extrusion head 28, it is in a vertical state under the action of gravity and becomes a plastic strip;

[0045] S2, at this time, the iron rod 8 is driven by the driving assembly to move along the guide rail 7, and the iron rod 8 first moves along the horizontal section of the guide rail 7, so that the drooping plastic strip is pushed, and the plastic strip sticks to the surface of the iron rod 8 after contacting the iron rod 8, and then moves along the guide rail 7 into the cooling pool 3 with the plastic strip, enters the cooling water of the cooling pool 3, and then moves along another horizontal section of the guide rail 7 in the cooling water, and then moves along the guide rail 7 to the outside of the cooling pool 3 and leaves the cooling water;

[0046] S3. At this time, the staff can remove the iron rod 8, hold the iron rod 8 and move the plastic strip cooled by cooling water, and then separate the iron rod 8 from the plastic strip with scissors, put the plastic strip into the crusher 4 for crushing, so that the plastic strip is crushed into masterbatch. During the whole process, the staff does not need to hold the iron rod 8 close to the extrusion head 28 to perform the strip pulling operation, which can avoid the staff from being scalded by the extrusion head 28 and make the strip pulling operation easier.

[0047] Working principle: When in use, the waste plastic is melted by the melting device 2, and then the melted waste plastic is introduced into the extruder, and then extruded through the extruder head 28. After the extruded plastic leaves the extruder head 28, it is in a vertical state under the action of gravity and becomes a plastic strip. The motor 16 is started to rotate its output shaft forward, thereby driving the reel 17 to rotate, reeling the pull rope 18, and then driving the slider 13 to move with the vertical plate 9, the cross bar 10, the connecting plate 11, the magnet sheet 12 and the iron rod 8 in the direction away from the base 1. When the slider 13 moves, it compresses the first spring 15 to deform it and produce an action. With the movement of the iron rod 8, the iron rod 8 first moves along the horizontal section of the guide rail 7, so that the drooping plastic strip is pushed. After the plastic strip contacts the iron rod 8, it sticks to the surface of the iron rod 8, and then moves along the guide rail 7 into the cooling pool 3 with the plastic strip, enters the cooling water of the cooling pool 3, and then moves along another horizontal section of the guide rail 7 in the cooling water, and then moves along the guide rail 7 to the outside of the cooling pool 3 and leaves the cooling water. At this time, the staff can pull the iron rod 8 to move it in the direction close to the top wall of the guide rail 7, that is, close to the base 1, so that the iron rod 8 is separated from the magnet sheet 12, and then take The iron rod 8 moves with the plastic strip cooled by cooling water, and then the iron rod 8 is separated from the plastic strip by scissors, and the plastic strip is put into the crusher 4 for crushing, so that the plastic strip is crushed into masterbatch. During the whole process, there is no need for the staff to hold the iron rod 8 close to the extruder head 28 to pull the strip, which can avoid the staff from being scalded by the extruder head 28 and make the operation of pulling the strip easier. Then, the motor 16 is started to reverse its output shaft, so that the pull rope 18 is released, and the first spring 15 releases the force to reset the slider 13, so that the vertical plate 9 moves and resets accordingly. In this process In the process, the magnet sheet 12 moves along the guide rail 7 and finally resets, and the electric push rod 19 is started to shorten it and bring the lifting plate 20 and the closing plate 21 down, so that the opening is opened, and the iron rod 8 located in the inclined groove 29 moves along the inclined groove 29 until it contacts the magnet sheet 12 so that it is adsorbed and fixed, and then the electric push rod 19 is started to extend it, so that the closing plate 21 can be reset, thereby closing the opening, and the reset of the iron rod 8 is completed. If the plastic strip is disconnected during the pulling process, the iron rod 8 can be removed, and the new iron rod 8 can be connected to the magnet sheet 12 in the above manner, and the pulling operation of the plastic strip can be performed again;When the magnet sheet 12 moves along the guide rail 7 in the cooling water, impurities will adhere to the contact surface between the magnet sheet 12 and the iron rod 8, affecting the subsequent adsorption and fixing effect on the iron rod 8. Therefore, when the connecting plate 11 moves in the direction away from the base 1, it brings the side plate 24, the stopper 25 and the squeezing rod 26 to move along with it. When the squeezing rod 26 conflicts with the squeezing block 27, the squeezing rod 26 rotates to avoid the squeezing block 27. After the squeezing rod 26 leaves the squeezing block 27, under the action of gravity, the squeezing rod 26 rotates downward to reset. In the process of resetting the connecting plate 11, the squeezing rod 26 conflicts with the arc surface of the squeezing block 27. At this time, due to the existence of the stopper 25, the squeezing rod 26 The rod 26 cannot rotate and remains in a vertical state, thereby driving the side plate 24, the connecting plate 11, and the magnet sheet 12 to move away from the iron rod 8 along the arc surface, so that the second spring 23 is compressed to deform and generate a force. When the extrusion rod 26 leaves the extrusion block 27, the second spring 23 releases the force and quickly resets the connecting plate 11 and the magnet sheet 12, so that the baffle 22 collides with the inner wall of the moving groove to generate vibration, and the vibration is transmitted to the magnet sheet 12, so that the impurities attached to the magnet sheet 12 are shaken off, so that the impurities are separated from the magnet sheet 12, and the magnet sheet 12 is cleaned, so that the subsequent magnet sheet 12 and the iron rod 8 can be stably adsorbed and fixed. ;

[0048] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
