Description

Technical Field

[0001] This utility model relates to the field of extruder technology, and in particular to a quantitative cutting device for an extruder. Background Technology

[0002] The application and function of extruders are mainly reflected in their ability to heat polymer compounds to a molten state and, through the extrusion action of the screw, shape them into continuous profiles with a constant cross-sectional shape through a die. Extruders have a wide range of applications in plastic processing. After the material is extruded, it needs to be cut.

[0003] Current extruder cutting devices can usually only cut according to preset dimensions, which greatly limits their application range and flexibility. Especially when different lengths of pipe are required, the fixed cutting dimensions make this process particularly inconvenient, requiring additional cutting or splicing, which in turn increases the cost. In order to better address the above problems, promote the development of industry technology, and improve core competitiveness, this application proposes a new composition structure that is different from the existing technology. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quantitative cutting device for an extruder.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are all within the protection scope of the present utility model.

[0024] Reference Figures 1-4 A quantitative cutting device for an extruder includes a frame 6, one end of which is fixed with a guide box 2 by bolts. A guide port is provided in the middle of the guide box 2, and the guide box 2 can be adapted to the extruder body 1.

[0025] In the prior art, the extruder body 1 includes a screw, a barrel, a heating and cooling mechanism, a drive device, and a die head. The die head can correspond to the position of the feed inlet of this application. When the die head discharges material, the extruded material enters the feed box 2 from the feed inlet of the feed box 2 and then exits from the other end.

[0026] The solution aims to protect the following: a PLC controller is installed on the guide box 2, and a cutting assembly is provided on one side of the guide box 2. The cutting assembly includes a fixed base 12, which is fixed to the outer wall of one side of the guide box 2 by bolts. The driving component is a cylinder 13, and a solenoid valve is connected to the air pipe of the cylinder 13. The air pipe of the cylinder 13 is connected to an external air pump. The cylinder 13 is fixed to the outer wall of one side of the fixed base 12 by bolts. A cutting blade 11 is installed at one end of the piston rod of the cylinder 13.

[0027] Two fixing blocks 5 are bolted to the top of the frame 6. Two guide rods 4 are bolted between the two fixing blocks 5. A slider 3 is slidably connected between the two guide rods 4. A locking bolt 20 is threaded onto the slider 3, and the locking bolt 20 can contact the top of the frame 6. The operator pushes the slider 3 to the required length and with reference to the scale 10, so that the slider 3 moves along the guide rods 4 to the required position. Then, the locking bolt 20 is rotated so that its bottom end is in close contact with the frame 6, so that the slider 3 is positioned. A magnetic switch 19 is bolted to the slider 3. The magnetic switch 19 can be selected as an MR6133 magnetoresistive Hall magnetic switch, which integrates a single MR magnetoresistive element and a CMOS switch, supports pulse signal output, has a built-in button battery, and can be directly connected to a PLC controller.

[0028] The upper surface of the frame 6 is provided with a scale 10, and the bottom of the slider 3 points to the scale on the scale 10, which makes it easy for the staff to directly understand the distance the slider 3 moves, and thus make it easy to adjust the cutting length of the extruded material of the extruder body 1.

[0029] A guide frame 18 is slidably connected to the slider 3. Springs 17 are sleeved on the outer sides of multiple sliding rods on the guide frame 18, and the two ends of the springs 17 are fixed to the guide frame 18 and the slider 3 respectively. The detection end of the magnetic switch 19 is in contact with the guide frame 18. The material extruded from the extruder body 1 is discharged through the die head and gradually enters the guide port of the guide box 2 until the first end of the extruded material contacts the guide frame 18. During the discharge process, the material continuously moves and squeezes the guide frame 18, causing the guide frame 18 to move along the slider 3, and the springs 17 contract until the square plate of the guide frame 18 contacts the magnetic switch 19. The magnetic switch 19 transmits a signal to the PLC controller, which starts the cylinder 13. The cylinder 13 extends to move the cutting blade 11, thereby cutting the material at the outlet end of the guide box 2.

[0030] In this utility model, it should be noted that a material rack 9 is rotatably connected to one side of the frame 6, and an electric push rod 16 is fixed to the bottom of the frame 6 by bolts. A slide 15 is fixed to the extended end of the electric push rod 16 by bolts. Rollers 14 are rotatably connected to the top of multiple vertical rods on the slide 15, and the rollers 14 are in contact with the bottom of the material rack 9. The rollers 14 make the slide 15 move along the material rack 9 more smoothly.

[0031] Among them, the solenoid valve of cylinder 13, electric push rod 16, and magnetic switch 19 are all controlled by PLC controller;

[0032] A collection box 7 is fixed to one side of the frame 6 by bolts, and the material rack 9 is located on the side of the collection box 7. After the material is cut, it falls onto the material rack 9. The electric push rod 16 is retracted, which causes the slide 15 to drive the roller 14 to move downward. At this time, the material rack 9 rotates downward and the inclination gradually increases, so that the material after cutting moves into the collection box 7 along the slope of the material rack 9, which is convenient for the staff to handle in a concentrated manner.

[0033] Two blocking plates 8 are fixed to one side of the frame 6 by bolts, and the blocking plates 8 are in contact with the upper surface of the material rack 9. The blocking plates 8 can limit the upward rotation of the material rack 9 and prevent the material rack 9 from moving excessively.

[0034] The working principle of this utility model is as follows: When it is necessary to cut the material extruded from the extruder body 1, the operator first pushes the slider 3 to the required cutting length, referring to the scale 10, so that the slider 3 moves along the guide rod 4 to the required position. Then, the locking bolt 20 is rotated to make its bottom end tightly contact the frame 6, thus positioning the slider 3. Then, the material extruded from the extruder body 1 is discharged through the die head and gradually enters the guide port of the guide box 2 until the beginning of the material contacts the guide frame 18. During the discharge process, the material continues to move and squeeze the guide frame 18, causing it to move along the slider 3. Spring 17 contracts until the square plate of guide frame 18 contacts magnetic switch 19. Magnetic switch 19 transmits a signal to PLC controller, which then controls the solenoid valve to start cylinder 13. Cylinder 13 extends, causing cutting blade 11 to move, thereby quantitatively cutting the material at the outlet of guide box 2. The cut material falls onto material rack 9, activating electric push rod 16. Electric push rod 16 contracts, causing slide 15 to drive roller 14 downward. At this time, material rack 9 rotates downward, and the inclination gradually increases, causing the cut material to move into collection box 7 along the slope of material rack 9.

[0035] Furthermore, the terms "installation," "setup," "connection," and "socketing" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral constructions; they can refer to mechanical or electrical connections; they can refer to direct connections or indirect connections via an intermediate medium, or internal connections between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
