Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pelletizing equipment, in particular to a novel pelletizer. Background Art
[0002] A pelletizer is a device that pelletizes raw materials of various shapes such as strips. The main structure of an existing pelletizer includes a cutter, a motor reduction mechanism, a connecting rod, a crankshaft, a cutter, etc. When working, the power output by the motor reduction mechanism acts on the connecting rod through the crankshaft, and the connecting rod drives the cutter to move up or down, thereby pelletizing the raw materials continuously fed under the cutter by the staff. At present, there is also a pelletizer that drives the blade to rotate through a motor, and then pelletizes the raw materials continuously fed under the cutter by the staff.
[0003] Although the existing pelletizers have met the processing needs to a certain extent, they are limited by their structure and still have the following shortcomings that need to be improved. (1): The pelletizer composed of a motor reduction mechanism, a connecting rod, a crankshaft, and a cutter has a relatively complex structure, and has relatively many moving working parts, and the corresponding probability of failure is also relatively high. (2): The pelletizer composed of a motor and a blade has a limited outer diameter of the cutting blade. Compared with a cutter with a longer lateral distribution, the amount of raw materials cut each time is limited, so the speed of cutting the raw materials is relatively slow. (3): All existing pelletizers do not have a protective mechanism. Therefore, when the staff's hands are too close to the blade for various reasons, there is a possibility of injury to the hands. In summary, it is particularly necessary to provide a pelletizer that has a relatively compact structure, is easy to use, has high pelletizing efficiency, and can prevent the staff's hands from being injured as much as possible. Utility Model Content
[0004] In order to overcome the drawbacks of the existing pelletizers as described in the background due to structural limitations, the utility model provides a new type of pelletizer that, under the joint action of relevant mechanisms, controls the working mode of the electromagnet through a time-controlled switch, drives the cutter to move up or down to pelletize the raw materials. The equipment as a whole is relatively more compact, has a lower probability of failure, and has higher processing efficiency. It can also monitor the distance between the staff's hands and the cutter in real time during operation, and automatically shut down the main power supply when the hand is too close to the cutter, thereby minimizing injuries to the staff's hands and the like.
[0005] The technical solution adopted by the utility model to solve its technical problems is:
[0006] A novel pelletizer comprises a workbench, an electromagnet, a cutter, a fixed frame, and a linear bearing, characterized in that it also has a control circuit; the lower ends of the fixed frame are respectively mounted on the upper ends of the workbench, the upper end of the fixed frame has a plurality of mounting holes, there are multiple sets of linear bearings, the outer sides of the sleeves of the multiple sets of linear bearings are respectively mounted in the multiple mounting holes, the shafts of the multiple sets of linear bearings are respectively slidably sleeved in the sleeves of the multiple sets of linear bearings, and the lower ends of the shafts of the multiple sets of linear bearings are respectively mounted on the upper end of the cutter; the outer ends of the shafts of the multiple sets of linear bearings are respectively sleeved with springs, and the upper ends of the shafts of the multiple sets of linear bearings are respectively mounted on the lower ends of a connecting plate, the electromagnet is mounted on the upper end side of the fixed frame, and the lower end of the connecting plate is mounted with a steel material suction plate; the blade of the cutter is a hollow structure above the blade, and a plurality of electric heating plates are installed in the blade; the control circuit is equipped with a pyroelectric detection module, the pyroelectric detection module and the control circuit are installed in a component box, and the component box is installed at the front side of the fixed frame; the power output end of the control circuit is electrically connected to the power input end of the electromagnet.
[0007] Furthermore, the rear end of the workbench is an inclined structure.
[0008] Furthermore, the attraction surface of the electromagnet and the attraction plate are vertically located in a vertical plane.
[0009] Furthermore, when the connecting plate descends to the stop point, the lower end of the cutter and the upper end of the workbench are spaced a certain distance apart, and when the connecting plate ascends to the stop point, the spacing between the lower end of the cutter and the upper ends of the workbenches is greater than the outer diameter of the cut raw material.

The power output end of the pyroelectric detection module is connected to the positive power input end of the relay, the negative power input end of the pyroelectric detection module is connected to the negative power input end of the relay, and the two normally open contact ends of the relay are electrically connected to the power input end of the time-controlled switch.
[0011] Compared with the prior art, the present invention has the following beneficial effects: (1): The main structure of the present invention includes a cutter, an electromagnet, etc. Compared with a pelletizer composed of a motor reduction mechanism, a connecting rod, a crankshaft, and a cutter, the structure is relatively simple and compact, and the number of moving working parts is relatively small (except for the linear bearing movement), and the probability of corresponding failure is relatively small; (2): During operation, the control circuit can monitor the distance between the worker's hand and the cutter in real time, and can automatically shut down the main power supply when the hand is too close to the cutter, thereby minimizing the probability of the worker's hand being injured. (3): The electric heating plate in the present application can heat the cutter, so that the probability of the material strip not being broken during cutting can be reduced (the heated blade and heat will melt the material strip, so it can especially improve the cutting effect of the lower layer of material strip in contact with the work surface), and the cutting effect is relatively better.

The two sets of electromagnets DC are bolted to the outer sides of the upper end of the fixing frame 3. A steel suction plate 8 is welded to the lower sides of the connecting plate 7. The blade 22 above the blade of the cutter is a hollow structure. Four electric heating plates RT are installed at a certain distance on the left and right sides of the blade 22. The power input ends of the four electric heating plates RT9 are connected in parallel and guided to the outside through the upper opening at the right end of the blade 22. The control circuit is equipped with a pyroelectric detection module W2. The power switch, power module W1 and control circuit 5 are installed on the circuit board in the component box 7. The component box 7 is installed in the middle of the front side of the fixing frame 3, and the detection surface of the pyroelectric detection module W2 is located outside the opening at the front side of the component box 7. The rear side of the workbench 1 is an inclined structure.
[0016] Figure 1 , 2As shown in , the suction surface of the electromagnet DC and the suction plate 8 are vertically located in a vertical plane and are 4 cm apart. When the connecting plate 7 moves downward to the dead point, the lower end of the cutter 2 and the upper end of the workbench 1 are spaced a certain distance (1 mm). When the connecting plate 7 moves upward to the dead point, the spacing between the lower end of the cutter 2 and the upper end of each workbench 1 is greater than the outer diameter of the cut raw material (such as multiple plastic strips). The control circuit includes a power switch S1, a relay K1, and a time switch W3 connected by circuit board wiring, and is connected to the pyroelectric detection module W2 via a wire. One end of the power switch S1 is connected to the positive power input terminal 1 of the pyroelectric detection module W2, the power output terminal 3 of the pyroelectric detection module W2 is connected to the positive power input terminal of the relay K1, the negative power input terminal 2 of the pyroelectric detection module W1 is connected to the negative power input terminal of the relay K1, and the two normally closed contact ends of the relay K1 are connected to the power input terminals 1 and 2 of the time switch W3 via wires. The power input terminals 1 and 2 of the power module W1, the two control power input terminals of the relay K1 of the control circuit, and the power input terminals 1 and 2 of the four electric heating plates RT are connected in series through the power switch S2 and the two poles of the AC 220V power supply are connected through wires, the power output terminals 3 and 4 of the power module W1 and the other end of the power input terminal of the control circuit power switch S1 and the negative power input terminal of the relay K1 are connected through wires, and the 3 and 4 pins of the time control switch W3 at the power output terminal of the control circuit and the two ends of the power input of the two sets of electromagnets DC are connected through wires. The handles of the power switches S1 and S2 are located outside the two openings at the front end of the component box.
[0017] Figure 1 , 2As shown in , the main structure of the new type includes a cutter, an electromagnet, etc. Compared with a pelletizer composed of a motor reduction mechanism, a connecting rod, a crankshaft, and a cutter, its structure is relatively simple and compact, and there are relatively few moving working parts (except for the linear bearing movement), and the corresponding probability of failure is relatively small. After the 220V AC power supply enters the power input end of the power module W1, the 3rd and 4th pins of the power module W1 output a stable DC 24V power supply and enter the power input end of the power switches S1 and S2. When the new type of pelletizing is performed, the staff holds the plastic, material strips, etc. that need to be cut in their hands, and transports the material strips backward along the front end of the workbench under the cutter. After subsequent cutting, the pellets fall through the inclined part at the rear end of the workbench and enter the material frame (not shown in the figure) at the rear end of the workbench. Before cutting, turn on the power switch S2, so that the four sets of electric heating plates RT can generate electricity to heat the cutters. Since the cutters are heated during operation, the probability of unbroken material strips during cutting can be reduced (the heated blades and heat will melt the material strips, so the cutting effect of the lower layer of material strips in contact with the work surface can be particularly improved), and the cutting effect is relatively better. After turning on the power switch S1, the control circuit is powered on and starts working. When the staff detects that the front end of the interval cutter 2 is appropriate, that is, when the front end of the interval pyroelectric detection module W2 detection head is greater than the appropriate distance (for example, greater than 30 cm), the 3rd pin of the pyroelectric detection module W2 does not output a high level, and the relay K1 will not be powered on and attracted. Then the 220V AC power supply will enter the power input end of the time control switch W3 through the power input end and the normally closed contact end of the relay K1 control. After the time control switch W3 is powered on, its 3rd and 4th pins will cyclically output 2 seconds of power (time is adjustable) to the power input end of the two sets of electromagnet DC every 2 seconds. The electromagnet DC will cyclically be powered for 2 seconds every 2 seconds. During the time when the electromagnet DC is powered on, a strong suction force is generated to attract the connecting plate 7 downward through the suction plate 8. During the time when the electromagnet DC is powered off, the spring 6 pushes the connecting plate 7 to move upward via the linear bearing. The above process is continuously circulated, which will reciprocate and drive the cutter to move up or down continuously, and the staff will continuously hand-feed the raw materials under the cutter for cutting operations. In the present application, if the staff detects that the front end of the interval cutter 2 is too close, that is, when the front end of the detection head of the interval pyroelectric detection module W2 (the detection surface is located outside the opening in the middle of the front end of the component box) is less than the appropriate distance (for example, less than 30 cm), the 3rd pin of the pyroelectric detection module W2 outputs a high level, and the relay K1 is energized to close its control power input terminal and the normally closed contact terminal to open the circuit. Then, the 220V AC power supply no longer enters the power input terminal of the time control switch W3 through the control power input terminal and the normally closed contact terminal of the relay K1. After the time control switch W3 loses power, its 3rd and 4th pins no longer output power to the power input terminals of the two sets of electromagnet DC, and the electromagnet DC no longer drives the cutter up and down, thereby minimizing the chance of injuries to the hands of the staff. Figure 2In the figure, the power module W1 is a finished product of an AC 220V to DC 24V power module; the relay K1 model is DC24V; the time control switch W3 is a finished product of a time controller model KG316T, which has two power input terminals, two power output terminals, and seven setting buttons. The seven buttons can be operated separately to set the time for the power output terminal to output power; the electromagnet DC is a 200W high-power suction cup electromagnet of model YR-P65 / 30; the electric heating plate RT is a finished product of a PTC constant temperature electric heating plate with a power of 200W (temperature 100°C); the pyroelectric detection module W2 is a finished product of a pyroelectric infrared sensing electronic module model HC-SR501, which has two power input terminals and a signal output terminal, and has a distance adjustment knob inside. Adjusting the detection distance to the left increases the detection distance and adjusting the detection distance to the right decreases the detection distance. In this embodiment, it is preferably adjusted to 30 cm).
