Description

Technical Field

[0001] This utility model relates to the field of screenless die head technology, and more specifically, to a screenless die head equipped with an automatic debris removal mechanism. Background Technology

[0002] A screenless die is a mold component used in plastics processing and other fields. It differs from a traditional die in that it eliminates the need for a filter screen. Its unique structural design effectively filters impurities while ensuring uniform material extrusion. Screenless dies improve production efficiency, reduce downtime due to filter replacements, and lower production costs. Furthermore, they improve product quality, resulting in smoother extruded surfaces and higher dimensional accuracy, making them widely used in the production of plastic pipes and sheets.

[0003] The meshless die head mainly consists of a die head cylinder, a feeding zone, a filter screen, a discharge zone, and a heating and cleaning system. During operation, the plastic raw material enters through the feeding zone, is heated to a suitable processing temperature by the heating system, and then passes through a filter screen with micropores. Impurities are intercepted, while the melt passes through and is discharged from the discharge zone. Simultaneously, the cleaning system periodically cleans the filter screen. This eliminates the need for frequent filter screen replacements, significantly improving plastic processing efficiency.

[0004] In the prior art, some meshless die heads equipped with automatic impurity removal mechanisms experience vibrations during prolonged operation and automatic impurity removal. Prolonged vibration necessitates maintenance of the pressure sensor, but the sensor cannot be quickly disassembled and reassembled. This lack of timely maintenance affects the sensor's measurement accuracy, consequently impacting the meshless die head's precise pressure control during production. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a meshless mold head with an automatic impurity removal mechanism, so as to solve the problem that pressure sensors cannot be quickly disassembled and installed due to long-term vibration in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a screenless die head equipped with an automatic waste removal mechanism, comprising...

[0007] The housing has a pressure sensor movably connected to its inner wall, and a connecting shell movably connected to the outside of the pressure sensor. Two buttons are slidably connected to the inner wall of the connecting shell, and a retaining plate is fixedly connected to the outside of each button. A retaining pin is movably connected to the inner wall of the retaining plate, and an S-shaped elastic element is fixedly connected to the end of the retaining plate away from the button. Two slots are formed on the inner wall of the housing, and a control component for controlling subsequent components is fixedly connected to the outside of the pressure sensor.

[0008] The control component includes a knob, which is fixedly connected to the outside of the pressure sensor. A conduit is fixedly connected to the inner wall of the pressure sensor. A processor is fixedly connected to the end of the conduit away from the pressure sensor. A control box is fixedly connected to the outside of the conduit. A controller is fixedly connected to the end of the processor away from the conduit. An alarm is fixedly connected to the end of the controller away from the processor.

[0009] A connecting block is fixedly connected to the outside of the control box, and a motor is fixedly connected to the outside of the connecting block.

[0010] The card plate is externally movably connected to the inner wall of the card slot, and the two ends of the card pin are fixedly connected to the inner wall of the connecting shell.

[0011] The card plate is movably connected to the inner wall of the connecting shell, and the end of the S-shaped elastic element away from the card plate is fixedly connected to the inner wall of the connecting shell.

[0012] The outer surface of the card plate is in contact with the outer surface of the outer shell, and the outer surface of the connecting shell is in contact with the outer surface of the outer shell.

[0013] The processor is externally fixedly connected to the inner wall of the control box, and the controller is externally fixedly connected to the inner wall of the control box.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In the above solution, pressure is applied to the S-shaped elastic element by pressing the button on the top of the connecting shell. At this time, the card plate will leave the slot inside the shell and will no longer be engaged. Then, it can be pulled out and disassembled through the connecting shell. Because the equipment will vibrate during long-term operation and automatic impurity removal, the pressure sensor needs to be maintained under the influence of long-term vibration. Quick disassembly and reassembly of the pressure sensor provides convenience for equipment maintenance and also improves production efficiency.

[0016] In the above solution, by setting up a control component, the pressure sensor receives pressure and transmits the signal to the processor through a conduit. After processing by the processor, the signal is transmitted to the controller. After receiving the processed content from the processor, the controller sends a command to the alarm to control the alarm to sound an alarm, thus protecting the meshless die head from damage to the drive motor due to excessive pressure and extending the service life of the meshless die head and scraper.

[0024] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0025] As attached Figure 1 To be continued Figure 5 An embodiment of this utility model provides a screenless die head equipped with an automatic waste removal mechanism, including...

[0026] The outer casing 1 serves as the external protective structure for the meshless die head, providing space for the installation and operation of internal components. A pressure sensor 2 is movably connected to the inner wall of the outer casing 1. The pressure sensor 2 can detect pressure changes inside the meshless die head in real time, and responds promptly to automatically remove impurities when the internal pressure changes. A connecting shell 3 is movably connected to the pressure sensor 2, serving to connect and protect it, while also facilitating its connection and operation. Two buttons 4 are slidably connected to the inner wall of the connecting shell 3. These buttons 4 are key components used to trigger subsequent disassembly operations; pressing them controls the disassembly of the connecting shell 3. A locking plate 5 is fixedly connected to the outside of each button 4. The locking plate 5 is linked to the button 4; when a button 4 is pressed, the locking plate 5 moves accordingly. A locking pin 6 is movably connected to the inner wall of the locking plate 5, serving as a fulcrum for its rotation, allowing the locking plate 5 to rotate around its center, thereby engaging or disengaging with the locking slot 8. An S-shaped elastic element 7 is fixedly connected to the end of the card plate 5 away from the button 4. The S-shaped elastic element 7 has good elasticity and can deform when the card plate 5 is subjected to pressure. It can also return to its original shape after the pressure is removed, thereby maintaining the engagement state between the card plate 5 and the card slot 8. Two card slots 8 are opened on the inner wall of the outer shell 1. The card slots 8 cooperate with the card plate 5. When the card plate 5 is engaged in the card slot 8, the connecting shell 3 and the outer shell 1 remain relatively fixed. Because the equipment will vibrate during long-term operation and automatic impurity removal, the pressure sensor 2 needs to be maintained under the influence of long-term vibration. The quick disassembly and reassembly of the pressure sensor 2 provides convenience for equipment maintenance and also improves production efficiency.

[0027] The control component includes a knob 9, which allows operators to manually adjust and set the control component to meet different working needs. The knob 9 is externally fixed to the pressure sensor 2, ensuring a tight connection and easy operation. A conduit 10 is fixedly connected to the inner wall of the pressure sensor 2. The conduit 10 protects the internal wiring from damage and also ensures stable signal transmission. A processor 15 is fixedly connected to the end of the conduit 10 furthest from the pressure sensor 2. The processor 15 processes and analyzes the received pressure signal to determine the internal working status of the meshless die head. A control box 11 is fixedly connected to the outside of the conduit 10. The control box 11 is the core of the control component, providing space for the processor 15, controller 16, and other components for installation and protection. The controller 16 is fixedly connected to the end of the processor 15 furthest from the conduit 10. Based on the processing results of the processor 15, the controller 16 issues control commands to the alarm 12 and other actuators to achieve the corresponding functions. An alarm 12 is fixedly connected to the end of the controller 16 away from the processor 15. After receiving the command from the controller 16, the alarm 12 will issue an alarm signal to remind the operator that there is an abnormality inside the meshless head and that it needs to be dealt with in time.

[0028] A connecting block 13 is fixedly connected to the outside of the control box 11. The connecting block 13 is used to connect the control box 11 and the motor 14, so that the motor 14 can work together with the control box 11. The motor 14 is fixedly connected to the outside of the connecting block 13. The motor 14 is the power source for the meshless mold head to realize functions such as automatic impurity removal. It can operate according to the instructions of the control box 11.

[0029] The external movable connection of the card plate 5 is to the inner wall of the card slot 8. When the card plate 5 is inserted into the card slot 8, the connecting shell 3 and the outer shell 1 remain relatively fixed to ensure the stability of each component when the meshless mold head is working normally. The two ends of the locking pin 6 are fixedly connected to the inner wall of the connecting shell 3, providing a stable fulcrum for the rotation of the card plate 5.

[0030] The clamping plate 5 is movably connected to the inner wall of the connecting shell 3, allowing the clamping plate 5 to rotate flexibly within the connecting shell 3 to achieve engagement and disengagement with the clamping groove 8. The end of the S-shaped elastic element 7 away from the clamping plate 5 is fixedly connected to the inner wall of the connecting shell 3. In this way, the S-shaped elastic element 7 can deform when the clamping plate 5 is subjected to pressure, and return to its original shape after the pressure is removed, maintaining the engagement state between the clamping plate 5 and the clamping groove 8.

[0031] The outer surface of the card plate 5 contacts the outer surface of the outer shell 1, ensuring a tight connection between the card plate 5 and the outer shell 1 and preventing loosening during operation. The outer surface of the connecting shell 3 contacts the outer surface of the outer shell 1, making the installation between the connecting shell 3 and the outer shell 1 more stable and improving the overall performance of the meshless mold head.

[0032] The processor 15 is externally fixedly connected to the inner wall of the control box 11, so that the processor 15 can be stably installed in the control box 11 and its normal operation is guaranteed. The controller 16 is externally fixedly connected to the inner wall of the control box 11, so that the connection between the controller 16 and the control box 11 is firm and the controller 16 can receive signals from the processor 15 and issue control commands.

[0033] The working process of this utility model is as follows:

[0034] First, press the button 4 on the top of the connecting shell 3. The button 4 applies pressure to the S-shaped elastic element 7 through the clamping plate 5. The clamping plate 5 rotates with the clamping pin 6 as the fulcrum under the pressure of the button 4, and the S-shaped elastic element 7 deforms and contracts under pressure. At this time, the clamping plate 5 will leave the clamping groove 8 inside the shell 1 and will no longer be engaged. Then, it can be pulled out and disassembled through the connecting shell 3. Because the equipment will vibrate during long-term operation and automatic impurity removal, the pressure sensor 2 needs to be maintained under the influence of long-term vibration. The quick disassembly and reassembly of the pressure sensor 2 provides convenience for equipment maintenance and also improves production efficiency.

[0035] During operation, when an internal blockage occurs, the pressure sensor 2 is subjected to pressure and transmits the signal to the processor 15 through the conduit 10. After processing by the processor 15, the signal is transmitted to the controller 16. After receiving the processed content from the processor 15, the controller 16 sends a command to the alarm 12 to control the alarm 12 to sound an alarm, protecting the meshless die head from damage to the drive motor due to excessive pressure, and extending the service life of the meshless die head and the scraper.
