Description

Technical Field

[0001] The present invention relates to the technical field of printing and forming equipment, and particularly relates to a high and low temperature printing and forming equipment. Background Art

[0002] In the fields of material research, industrial manufacturing, etc., the demand for printing and forming in high and low temperature environments is increasing day by day. High and low temperature printing and forming equipment can accurately construct materials into the required shapes under different temperature conditions, providing strong support for the manufacturing of various complex products; Since the printing and forming equipment may change the state of the printing material in the nozzle in high and low temperature environments, the material may carbonize and agglomerate at high temperatures, and the material may solidify and block the nozzle at low temperatures. Nozzle blockage will cause uneven extrusion of the material or even inability to extrude, seriously affecting the printing accuracy and continuity, and the nozzle needs to be frequently cleaned and maintained, reducing the work efficiency; At present, for existing printing and forming equipment, when the printing nozzle is blocked or needs to be cleaned, the disassembly and cleaning method is usually adopted. First, cut off the power supply of the printer. After the nozzle is completely cooled, carefully disassemble the nozzle assembly. Although this method can solve the blockage problem, the cleaning efficiency of the nozzle is reduced, making it difficult to meet the cleaning work requirements of the staff. Therefore, we propose a high and low temperature printing and forming equipment. Summary of the Invention

Detailed implementation mode

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment 1: Please refer to Figure 1 - Figure 13 , a high and low temperature printing and forming device, including: a base 1 and a frame 2 fixed to the base 1, and a loading platform 3 is arranged on the base 1. It further includes: a movable block 4 arranged on the frame 2, two guide rods 5 are fixed on the movable block 4, and a bearing support plate 6 is slidably connected to the guide rods 5. A housing 7 is fixed on the bearing support plate 6, a printing unit 8 is arranged on the housing 7, the printing unit 8 is used to heat and print materials into a formed shape, and a support plate 9 fixed on the bearing support plate 6, a clogging clearing mechanism 10 adapted to the printing unit 8 is arranged on the support plate 9, and the clogging clearing mechanism 10 is used to clean the clogging caused by materials; Specifically, a placement groove 56 is opened on the loading platform 3, a plurality of positioning rods 57 are fixed on the placement groove 56, a carrier plate 58 is snap-fitted in the placement groove 56, and a positioning hole 59 snap-fitted with the positioning rods 57 is opened on the carrier plate 58. By adding the placement groove 56 and the positioning rods 57, the purpose of quickly pre-positioning the carrier plate 58 is realized, so that the carrier plate 58 can be conveniently disassembled for cleaning and maintenance; Among them, an X-axis moving component for driving the loading platform 3 to move is arranged on the base 1, which mainly includes: a linear guide rail, a ball screw, a nut sleeve, a sliding rod, a slider 37 and an X-axis motor. The specific operation is as follows: the ball screw is driven to rotate by the X-axis motor, and the ball screw and the nut sleeve are used for transmission, and then the loading platform 3 is driven to translate along the linear guide rail, so that the translational movement of the loading platform 3 on the X-axis can be controlled, so as to realize the precise control of the movement process of the loading platform 3 on the X-axis. This is a conventional setting in this field, so it will not be described in detail here; In addition, a Y-axis moving component for driving the housing 7 to move up and down is arranged on the frame 2, which mainly includes: a threaded rod, a bevel gear and a Y-axis motor. The specific operation is as follows: the bevel gear is driven to rotate by the Y-axis motor, and the threaded rod is synchronously rotated by the transmission of the bevel gear. By using the threaded transmission between the threaded rod and the movable block 4, the movable block 4 is driven to move up and down, so as to realize the precise movement of the printing unit 8 on the Y-axis. This is a conventional setting in this field, so it will not be described in detail here; In addition, a Z-axis moving component for driving the translation movement of the housing 7 is provided on the bearing support plate 6. It mainly includes: a toothed belt b, a Z-axis motor, and a gear. The specific operation is as follows: The gear is driven to rotate by the Z-axis motor, and the gear meshes with the toothed belt b for transmission, thereby driving the bearing support plate 6 and the housing 7 to translate on the guide rod 5, so as to drive the printing unit 8 to move precisely on the Z-axis. This is a conventional setting in the art, so it will not be elaborated in detail here; Moreover, a wire feeding mechanism for extruding materials is provided on the bearing support plate 6. It mainly includes: rollers, a rotating shaft, a wire feeding motor, a driving gear, and bevel gears. The specific operation is as follows: The bevel gear is driven to rotate by the wire feeding motor, driving the rotating shaft to rotate synchronously, causing the driving gear to rotate synchronously, and sending the material into the throat pipe 17, thereby realizing the precise control of wire feeding. This is a conventional setting in the art, so it will not be elaborated in detail here; It should be noted that during the printing process, the printing material will be extruded through the nozzle 13. When the printing is completed, some materials may remain inside the nozzle 13, and the residual materials inside the nozzle 13 need to be cleared. The clogging clearing mechanism 10 is used to clean the printing materials inside the nozzle 13 to ensure that the nozzle 13 is in a state where it can be used normally.

[0020] Furthermore, as Figure 1 、 Figure 5 and Figure 8 shown, the printing unit 8 includes: a heating block 11 fixed on the support plate 9. A nozzle 13 is threadedly connected to the heating block 11 through a threaded groove 12. A thermostat 14 and a thermocouple 15 are respectively fixed on one side wall of the heating block 11. A heating tube 16 fixed to the heating block 11 is installed on the housing 7, and throat pipes 17 are fixed inside both the heating tube 16 and the heating block 11. A thermal cut-off 18 sleeved on the outer surface of the throat pipe 17 is installed inside the housing 7. An installation groove 19 is formed on the housing 7, and a cooling fan 20 is fixed inside the installation groove 19. A heat sink 21 in contact with the thermal cut-off 18 is fixed on the housing 7. The brush plate 46 is located on one side of the cooling fan 20, and a plurality of heat dissipation grooves 61 are formed on the housing 7; It should be noted that through the setting of the throat pipe 17, its function is to guide the wire material to smoothly enter the nozzle 13, and at the same time prevent the heat of the heating tube and the heating tube 16 from conducting upward, avoiding the wire material from melting before reaching the nozzle 13, ensuring the stability of wire feeding, and cooperating with the settings of the thermostat 14 and the thermocouple 15 to monitor the temperature in real time and feedback it to the control system to achieve precise temperature control. Under the action of the thermostat 14, the temperature of the heating block 11 can be maintained within a preset range value. When the temperature is too high, the thermal cut-off 18 intervenes to work to ensure that the temperature always remains in a constant temperature state. The cooling fan 20 and the heat sink 21 provide sufficient heat dissipation effect for the housing.

[0021] In this solution, the personnel use the blockage clearing mechanism 10 to clean according to the residual material impurities in the nozzle 13. The blockage clearing mechanism 10 is adjusted to a suitable position by the limiting member 33, and the remaining material in the nozzle 13 is cleaned by the blockage clearing mechanism 10, so that the blocked material in the nozzle 13 can be taken out, thus completing the cleaning work of the nozzle 13, keeping the nozzle 13 in a good and normal working state, and the blockage clearing mechanism 10 is adjusted to the position below the cleaning assembly 44 by the limiting member 33. The blockage clearing mechanism 10 is linked with the cleaning assembly 44 to drive the cleaning assembly 44 to clean the blades of the heat dissipation fan 20 to achieve the purpose of dust removal.

[0022] Embodiment 2: Refer to Figure 7 , Figure 8 , Figure 9 and Figure 11 As shown, this embodiment further describes Embodiment 1, and the difference lies in disclosing the method of cleaning the inside of the nozzle 13.

[0023] Furthermore, the blockage clearing mechanism 10 includes: a rod body 22 fixed on the support plate 9. A mounting plate 23 is slidably sleeved on the rod body 22. A cavity 24 is formed on the mounting plate 23. A micro motor 25 is fixed on the mounting plate 23. A spur gear a26 is fixed on the output shaft of the micro motor 25. A toothed belt a27 meshing with the spur gear a26 is slidably connected in the cavity 24. A through hole 28 is formed on the mounting plate 23. A threaded sleeve 29 is rotatably connected in the through hole 28. A tooth ring 30 meshing with the toothed belt a27 is fixed on the outer surface of the threaded sleeve 29. A screw rod 31 is threadedly connected to the threaded portion of the threaded sleeve 29. One end of the screw rod 31 is fixed with a spiral brush rod 32. A sponge wipe 60 is fixed on the mounting plate 23, and the sponge wipe 60 is in contact with the outer surface of the screw rod 31. The central axis of the sponge wipe 60 is collinear with the central axis of the threaded sleeve 29. By adding the sponge wipe 60, the thread groove position on the screw rod 31 can be cleaned, and it can prevent impurities from entering the threaded sleeve 29 and causing jamming. A limiting member 33 adapted to the rod body 22 is provided on the mounting plate 23; Specifically, the limiting member 33 includes a chute a34 formed in the rod body 22, a cylindrical groove a35 communicated with the chute a34 formed in the rod body 22, a chute b36 communicated with the cylindrical groove a35 formed in the rod body 22, a slider 37 fixed on the additional mounting plate 23 and slidably connected with the chute a34 and the chute b36, a cylindrical groove b38 communicated with the chute b36 formed in the rod body 22, a limiting rod 39 slidably penetrating through the additional mounting plate 23, a handle ball 40 fixed at one end of the limiting rod 39, a spring a41 sleeved on the outer surface of the limiting rod 39, one end of the spring a41 fixed to the handle ball 40, the other end of the spring a41 fixed to the additional mounting plate 23, a limiting hole a42 communicated with the cylindrical groove a35 formed in the rod body 22, a limiting hole b43 communicated with the cylindrical groove b38 formed in the rod body 22, and the limiting rod 39 being adapted to the limiting hole a42 and the limiting hole b43; It should be noted that through the setting of the clogging removal mechanism 10, the high-efficient and stable cleaning of the impurities and solidified materials inside the nozzle 13 can be realized. The mechanism uses the clogging removal method of spiral rotation movement, which can skillfully bring out the blocked materials to the outside of the nozzle 13. In this way, not only can the cleaning task of the blocked materials in the nozzle 13 be effectively completed, but also unnecessary damage to the inside of the nozzle 13 can be avoided during the process of cleaning the blocked materials, thereby ensuring the service life and spraying effect of the nozzle 13; Principle of limiting and releasing the additional mounting plate 23 using the limiting member 33: By pulling the handle ball 40, the limiting rod 39 moves synchronously until it is separated from the inside of the limiting hole b43, then the additional mounting plate 23 can be operated to rotate. Then, the additional mounting plate 23 is shifted to the position of the cylindrical groove b38, and the additional mounting plate 23 is rotated and placed below the nozzle 13 and aligned with the limiting hole a42. By the elastic action of the spring a41, until the limiting rod 39 is engaged with the inside of the limiting hole a42, the limiting state of the additional mounting plate 23 is completed; Principle of cleaning the nozzle 13 using the clogging removal mechanism 10: Driven by the micro motor 25, the spur gear a26 rotates synchronously. Using the meshing transmission between the spur gear a26 and the toothed belt a27, the toothed ring 30 is driven to rotate synchronously. Then, the threaded sleeve 29 rotates along the through hole 28. Using the threaded transmission between the threaded sleeve 29 and the screw rod 31, the screw rod 31 moves spirally upward under force, and then drives the spiral brush rod 32 to move synchronously. The inside of the nozzle 13 is cleaned by the spiral movement mode of the spiral brush rod 32. When the spiral brush rod 32 moves upward to the position in place, the micro motor 25 is driven to reverse, so that the spiral brush rod 32 moves spirally downward, and the material impurities in the nozzle 13 can be brought out to the outside of the nozzle 13.

[0024] Further, a cleaning component 44 adapted to the cooling fan 20 is provided on the outer shell 7. The cleaning component 44 includes: a rotating rod 45 is rotatably connected to the outer shell 7, a brush plate 46 is tightly sleeved on the outer surface of the rotating rod 45, a mounting plate 47 is fixed on the support plate 9, a channel 48 is formed on the mounting plate 47, a transmission column 49 is slidably connected in the channel 48, a connecting plate 50 is fixed at one end of the transmission column 49, two connecting rods 51 slidably penetrating through the mounting plate 47 are fixed on the connecting plate 50, a connecting ring 52 is fixed at one end of the connecting rod 51, a spring b53 is sleeved on the outer surface of the connecting rod 51, one end of the spring b53 is fixed to the connecting ring 52, the other end of the spring b53 is fixed to the mounting plate 47, and a connecting rod 54 is hinged between the connecting plate 50 and the brush plate 46; It should be noted that through the setting of the cleaning component 44, after the cleaning work of the nozzle 13 is completed, the cleaning component 44 can be further used to thoroughly clean the dust attached to the blades of the cooling fan 20. Such an operation can not only significantly save the time consumed by the staff in cleaning the dust on the blades of the cooling fan 20, but also realize linkage with the blockage clearing mechanism 10, so as to efficiently complete the cleaning work of the dust on the blades of the cooling fan 20. In this way, we can effectively avoid the problem of the decrease in the heat dissipation effect of the cooling fan 20 caused by dust attachment, and ensure that the cooling fan 20 can continuously maintain the best working state; The principle of using the cleaning component 44 to clean the dust attached to the cooling fan 20: By adjusting the mounting plate 23 to a position below the mounting plate 47, the driving screw 31 is driven by the micro motor 25 to perform a spiral upward or downward movement. By using the extrusion transmission effect between the spiral brush rod 32 and the transmission column 49, the transmission column 49 is forced to move upward. By using the transmission effect of the connecting rod 54, the brush plate 46 is forced to flip along the axis of the rotating rod 45. When the spiral brush rod 32 descends to a non-contact state with the transmission column 49, by using the elastic effect of the spring b53, the brush plate 46 is driven to rotate back to its original position, and then this movement trajectory is repeated to achieve the purpose of cleaning the blades of the cooling fan 20.

[0025] Example three: Refer to Figure 5 and Figure 6 As shown, this embodiment further illustrates other embodiments, and the difference lies in the optimization of the stability when the spiral brush rod 32 and the transmission column 49 are extruded and transmitted.

[0026] Specifically, a conical drill bit 55 is fixed at one end of the spiral brush rod 32. The central axis of the conical drill bit 55 is collinear with the central axis of the spiral brush rod 32. The length value of the transmission column 49 is greater than the thickness value of the mounting plate 47. A conical groove 62 adapted to the conical drill bit 55 is formed on the transmission column 49; It should be noted that by adding the conical drill bit 55 and the conical groove 62, not only can the stability during the pressing of the transmission column 49 be enhanced, but also the force on the spiral brush rod 32 can be relieved when cleaning the nozzle 13, avoiding the situation of poor stability caused by excessive pressure due to direct contact, which may lead to the shaking of the screw rod 31. It should also be noted that in accordance with the shape settings of the conical drill bit 55 and the conical groove 62, it is ensured that under the way of being extruded by spiral transmission, the transmission column 49 can still maintain relatively stable linear up-and-down movement, and the situation of jamming during the movement of the spiral brush rod 32 can be avoided.

[0027] The thermostat 14, the thermocouple 15, the heating block 11, the heating tube 16, the cooling fan 20 and the micro motor 25 can all be purchased on the market. They are mature technologies in this field and have been fully disclosed, so they will not be repeated in the specification.
