The U-shaped loading plate facilitates the loading of dust when the dust falls into the heat dissipation box. At the same time, the staff manually takes out the U-shaped loading plate to clean the dust in the U-shaped loading plate.

[0014] As a further solution of the present invention: a spring is fixedly connected to the side wall of the connecting plate, one end of the spring is fixedly connected to a push plate, and the push plate is fixedly connected to a plug rod, and one end of the plug rod is inserted on the side wall of the receiving groove. When the connecting plate needs to be removed from the receiving groove, the staff manually pushes the push plate, and the push plate drives the movement of the plug rod. When one end of the plug rod is detached from the receiving groove, the connecting plate can be removed from the receiving groove; when the connecting plate needs to be installed in the receiving groove, the staff manually pushes the push plate, and the push plate drives the movement of the plug rod, and then the connecting plate is placed in the receiving groove, and the push plate is manually released. Due to the action of the spring elastic force, the movement of the push plate is realized, and the movement of the plug rod is driven by the push plate. When one end of the plug rod is inserted on the side wall of the receiving groove, the connecting plate is installed in the receiving groove.

[0015] An elastic pad is fixedly connected inside the U-shaped fixing plate, and one end of the elastic pad is fixedly connected to the T-shaped plug rod. The material of the elastic pad is elastic material. When the U-shaped fixing plate needs to be removed, the staff manually pushes the T-shaped plug rod, and when one end of the T-shaped plug rod is removed from the connecting plate, the U-shaped fixing plate is removed; when the U-shaped fixing plate needs to be fixed, the staff manually pushes the T-shaped plug rod, and then places the U-shaped fixing plate in the storage groove, manually loosens the T-shaped plug rod, and the movement of the T-shaped plug rod is achieved due to the action of the elastic pad, and when one end of the T-shaped plug rod is inserted on the connecting plate, the U-shaped fixing plate is fixed.

[0016] The specific steps of the working principle of the servo hydraulic extruder are:

[0017] Manually rotate the adjusting bolt. Since the adjusting screw is threadedly connected to the second slider, the second slider moves during the rotation of the adjusting screw. Since the second slider is fixedly connected to the clamping plate, the clamping plate moves during the movement of the second slider, so that the two clamping plates move away from each other.

[0018] Manually push the T-shaped rod, then place the U-shaped fixing plate in the storage groove, manually loosen the T-shaped rod, and the elastic pad enables the T-shaped rod to move. When one end of the T-shaped rod is inserted on the connecting plate, the U-shaped fixing plate is fixed;

Since the second slider is fixedly connected to the clamping plate, the clamping plate moves during the movement of the second slider, so that the two clamping plates move toward each other, thereby clamping the extrusion screw housing.

[0021] Since the cooling box is filled with coolant, it is easy to achieve the heat dissipation effect when the extrusion screw housing is working;

[0022] When the height of the carrier plate needs to be adjusted, the first cylinder works to move the carrier plate, thereby adjusting the height value of the carrier plate, manually squeezing the elastic pad and placing the annular phase change plate in the through hole, and manually releasing the elastic pad. Due to the elastic force of the elastic pad, the annular phase change plate is locked in the through hole, and heat dissipation is facilitated by the annular phase change plate.

[0023] Since a charging box filled with cooling liquid is arranged in the heat dissipation box, heat dissipation is achieved through the heat dissipation holes during operation of the device, and dust is prevented from falling into the installation slot due to the dustproof net;

[0024] The U-shaped loading plate facilitates the loading of dust when the dust falls into the heat dissipation box, and the U-shaped loading plate can be manually taken out to clean the dust in the U-shaped loading plate.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] By placing a U-shaped loading plate on the heat dissipation box, the U-shaped loading plate facilitates the loading of dust when the dust falls into the heat dissipation box. At the same time, the staff manually takes out the U-shaped loading plate to clean the dust in the U-shaped loading plate.

[0027] A through hole is opened on the U-shaped support plate, an annular phase change plate is arranged in the through hole, and an elastic pad matching the through hole is arranged on the circumferential outer wall of the annular phase change plate. The annular phase change plate is a phase change material, so when the first cylinder is working, the temperature is reduced due to the action of the phase change plate; the staff manually squeezes the elastic pad to facilitate manual extraction of the annular phase change plate; when the annular phase change plate needs to be installed in the through hole, the staff manually squeezes the elastic pad and places the annular phase change plate in the through hole, and manually releases the elastic pad.

[0028] A spring is fixedly connected to the side wall of the connecting plate, one end of the spring is fixedly connected to a push plate, and a plug rod is fixedly connected to the push plate, and one end of the plug rod is inserted into the side wall of the accommodating groove. When the connecting plate needs to be removed from the accommodating groove, the staff manually pushes the push plate, and the push plate drives the movement of the plug rod. When one end of the plug rod is detached from the accommodating groove, the connecting plate can be removed from the accommodating groove; when the connecting plate needs to be installed in the accommodating groove, the staff manually pushes the push plate, and the push plate drives the movement of the plug rod, and then the connecting plate is placed in the accommodating groove, and the push plate is manually released. Due to the action of the spring elastic force, the push plate is moved, and the push plate drives the movement of the plug rod. When one end of the plug rod is inserted into the side wall of the accommodating groove, the connecting plate is installed in the accommodating groove.

[0029] An elastic pad is fixedly connected in the U-shaped fixing plate, one end of the elastic pad is fixedly connected to the T-shaped plug rod, and the material of the elastic pad is elastic.

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] See also Figure 1-10 In the embodiment of the present invention, a servo hydraulic extruder includes a servo motor 1, an oil pump 2, a computer 3, a hydraulic motor 4, an extrusion screw housing 5 and a discharge barrel 6, and also includes a bottom plate 7;

[0044] The pressure and speed of the extruder driving screw are set in the computer 3. The servo motor 1 works according to the instructions of the computer 3. The screw speed of the hydraulic motor 4 is uniform, the temperature control accuracy is high, and the qualified rate of the extruded products is higher than that of the general extruder. The temperature is not as good as the control of the controlled variables of pressure, flow, and liquid level, because there is a lag in temperature transmission. Among them, the object characteristic of lag time is involved, which generally has pure lag and capacity lag. The former generally refers to the time required for material transmission in the process section, and the latter generally refers to the heat exchange of the controlled object, and the time required for the material to pass through multiple containers continuously to establish a stable signal. The point is that the true value of the temperature cannot be reflected at once and it takes time to display the true value.

[0045] In temperature closed-loop control, in order to solve this problem, a PID temperature controller must be used. The key is to use D (differential control) in PID, and the role of differential control is advance control. Suppose there is a material temperature that needs to be controlled and it is desired to be controlled at 35°C (35°C is the target value). PID control includes P, PI, PD, PID and other controls. Considering that the controlled variable is temperature, PID control needs to be selected.

[0046] The temperature sensor detects the temperature, and the temperature value obtained at this time will be compared with the target value (35°) to obtain the deviation. Then the controller will make a quick judgment and send a signal to the actuator to adjust the temperature. At this time, a new dynamic temperature steady-state value will be obtained. The temperature sensor will send this value signal to the controller to compare with the target value to obtain a residual, so I integral control intervention is required. After the temperature controller processes and judges, it will send a signal to the actuator to adjust the temperature again. After reaching the new dynamic stability, the new steady-state value is transmitted to the controller. After comparing with the target value, the control is still not ideal and D differential control intervention is required. Therefore, PID parameter tuning is a boring process. Sometimes it takes a lot of effort to find the ideal PID three control parameter values ​​to improve the control quality.

[0047] To achieve dynamic stability of temperature control around 35°, PID parameter tuning is required. First use proportional, then integral, and finally differential. The temperature controller can automatically tune PID or manually tune PID.

An elastic pad 33 matching the through hole 31 is arranged on the circumferential outer wall of the annular phase change plate 32.

[0054] An adjusting screw 34 is threadedly connected to the upper surface of the supporting plate 9, and a second slider 35 is threadedly connected to the adjusting screw 34. A second sliding groove 43 for the sliding connection of the second slider 35 is opened on the supporting plate 9. The second slider 35 is fixedly connected to the clamping plate 10. The staff manually rotates the adjusting screw 34. Since the adjusting screw 34 is threadedly connected to the second slider 35, the second slider 35 moves during the rotation of the adjusting screw 34. Since the second slider 35 is fixedly connected to the clamping plate 10, the clamping plate 10 moves during the movement of the second slider 35.

[0055] A rectangular groove 36 is provided downwardly on the upper surface of the supporting plate 9, in which a rotating rod 37 is rotatably connected, and a roller 38 is fixedly connected to the rotating rod 37. Since the rotating rod 37 rotates in the rectangular groove 36, it is convenient for the roller 38 to rotate, thereby facilitating the movement of the extrusion screw housing 5 relative to the supporting plate 9, thereby adjusting the position of the extrusion screw housing 5.

[0056] A spring 39 is fixedly connected to the side wall of the connecting plate 15, one end of the spring 39 is fixedly connected to a push plate 40, and an insertion rod 41 is fixedly connected to the push plate 40. One end of the insertion rod 41 is inserted into the side wall of the receiving groove 14. When the connecting plate 15 needs to be removed from the receiving groove 14, the staff manually pushes the push plate 40, and the push plate 40 drives the movement of the insertion rod 41. When one end of the insertion rod 41 is detached from the receiving groove 14, the connecting plate 15 can be removed from the receiving groove 14. When the connecting plate 15 needs to be installed in the receiving groove 14, the staff manually pushes the push plate 40, and drives the insertion rod 41 to move through the push plate 40, and then places the connecting plate 15 in the receiving groove 14, manually releases the push plate 40, and the movement of the push plate 40 is achieved due to the elastic force of the spring 39, and drives the insertion rod 41 to move through the push plate 40. When one end of the insertion rod 41 is inserted into the side wall of the receiving groove 14, the connecting plate 15 is installed in the receiving groove 14.

[0057] An elastic pad 42 is fixedly connected inside the U-shaped fixing plate 18, and one end of the elastic pad 42 is fixedly connected to the T-shaped plug rod 19. The material of the elastic pad 42 is elastic material. When the U-shaped fixing plate 18 needs to be removed, the staff manually pushes the T-shaped plug rod 19. When one end of the T-shaped plug rod 19 is removed from the connecting plate 15, the U-shaped fixing plate 18 is removed; when the U-shaped fixing plate 18 needs to be fixed, the staff manually pushes the T-shaped plug rod 19, and then places the U-shaped fixing plate 18 in the storage groove 16, and manually loosens the T-shaped plug rod 19. Due to the action of the elastic pad 42, the T-shaped plug rod 19 is moved. When one end of the T-shaped plug rod 19 is inserted on the connecting plate 15, the U-shaped fixing plate 18 is fixed.

[0058] The specific steps of the working principle of the servo hydraulic extruder are:

[0059] The adjusting bolt 34 is manually rotated. Since the adjusting screw 34 is threadedly connected to the second slider 35, the second slider 35 moves during the rotation of the adjusting screw 34. Since the second slider 35 is fixedly connected to the clamping plate 10, the clamping plate 10 moves during the movement of the second slider 35, so that the two clamping plates 10 move away from each other.

[0060] Manually push the T-shaped rod 19, then place the U-shaped fixing plate 18 in the receiving groove 16, manually loosen the T-shaped rod 19, and the elastic pad 42 enables the T-shaped rod 19 to move. When one end of the T-shaped rod 19 is inserted on the connecting plate 15, the U-shaped fixing plate 18 is fixed;

[0061] The push plate 40 is manually pushed, and the insertion rod 41 is driven by the push plate 40 to move, and then the connecting plate 15 is placed in the receiving groove 14. The push plate 40 is manually released, and the push plate 40 is moved due to the elastic force of the spring 39, and the insertion rod 41 is driven by the push plate 40 to move. When one end of the insertion rod 41 is inserted into the side wall of the receiving groove 14, the connecting plate 15 is installed in the receiving groove 14.

[0062] Then, the extrusion screw housing 5 is placed between the two clamping plates 10, and the adjusting bolt 34 is manually rotated. Since the adjusting screw 34 is threadedly connected to the second slider 35, the second slider 35 moves during the rotation of the adjusting screw 34. Since the second slider 35 is fixedly connected to the clamping plate 10, the clamping plate 10 moves during the movement of the second slider 35, so that the two clamping plates 10 move toward each other, thereby clamping the extrusion screw housing 5.

[0063] Since the cooling box 17 is filled with coolant, it is convenient to achieve the heat dissipation effect when the extrusion screw housing 5 is working;

[0064] When the height of the carrier plate 9 needs to be adjusted, the first cylinder 30 works to move the carrier plate 9, thereby adjusting the height value of the carrier plate 9, manually squeezing the elastic pad 33 and placing the annular phase change plate 32 in the through hole 31, and manually releasing the elastic pad 33. Due to the elastic force of the elastic pad 33, the annular phase change plate 32 is conveniently locked in the through hole 31, and the heat dissipation effect is conveniently achieved through the annular phase change plate 32;

[0065] Since a charging box 26 filled with cooling liquid is arranged in the heat dissipation box 25, heat dissipation is achieved through the heat dissipation holes 27 during operation of the device, and dust is prevented from falling into the mounting groove 24 due to the function of the dustproof net 28;

[0066] The U-shaped loading plate 29 facilitates loading of dust when the dust falls into the heat dissipation box 25 , and the U-shaped loading plate 29 can be manually taken out to clean the dust in the U-shaped loading plate 29 .

[0067] When the present invention is in use, the staff manually rotates the adjusting bolt 34. Since the adjusting screw 34 is threadedly connected to the second slider 35, the second slider 35 moves during the rotation of the adjusting screw 34. Since the second slider 35 is fixedly connected to the clamping plate 10, the clamping plate 10 moves during the movement of the second slider 35, so that the two clamping plates 10 move away from each other.

[0068] The staff manually pushes the T-shaped rod 19, then places the U-shaped fixing plate 18 in the storage groove 16, and manually loosens the T-shaped rod 19. Due to the action of the elastic pad 42, the T-shaped rod 19 is moved. When one end of the T-shaped rod 19 is inserted on the connecting plate 15, the U-shaped fixing plate 18 is fixed.

[0069] The staff manually pushes the push plate 40, which drives the insertion rod 41 to move. Then, the connecting plate 15 is placed in the receiving groove 14, and the push plate 40 is manually released. Due to the elastic force of the spring 39, the push plate 40 is moved, and the insertion rod 41 is driven by the push plate 40 to move. When one end of the insertion rod 41 is inserted into the side wall of the receiving groove 14, the connecting plate 15 is installed in the receiving groove 14.

[0070] Afterwards, the extrusion threaded housing 5 is placed between the two clamping plates 10, and the staff manually turns the adjusting bolt 34. Since the adjusting screw 34 is threadedly connected to the second slider 35, the second slider 35 moves during the rotation of the adjusting screw 34. Since the second slider 35 is fixedly connected to the clamping plate 10, the clamping plate 10 moves during the movement of the second slider 35, so that the two clamping plates 10 move toward each other, thereby clamping the extrusion screw housing 5.

[0071] Since the cooling box 17 is filled with coolant, it is convenient to achieve the heat dissipation effect when the extrusion screw housing 5 is working.

[0072] When the height of the supporting plate 9 needs to be adjusted, the first cylinder 30 works to move the supporting plate 9, thereby adjusting the height value of the supporting plate 9. The staff manually squeezes the elastic pad 33 and places the annular phase change plate 32 in the through hole 31, and manually releases the elastic pad 33. Due to the elastic force of the elastic pad 33, the annular phase change plate 32 is easily locked in the through hole 31, and the heat dissipation effect is facilitated by the annular phase change plate 32.

[0073] Since a charging box 26 filled with cooling liquid is arranged in the heat dissipation box 25 , heat dissipation is achieved through the heat dissipation holes 27 during operation of the device, and the dustproof net 28 prevents dust from falling into the mounting groove 24 .

[0074] The U-shaped loading plate 29 facilitates loading of dust when the dust falls into the heat dissipation box 25 , and the staff manually takes out the U-shaped loading plate 29 to clean the dust in the U-shaped loading plate 29 .

[0075] The "fixed connection" described in the present invention means that the two interconnected parts are fixed together, generally by welding, screws or gluing; "rotational connection" means that the two parts are connected together and can move relative to each other.
