[0005] The purpose of the present invention is to solve the problems in the background technology and to propose a double-color latex tube annular barrel type extrusion batching mechanism.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a two-color latex tube annular barrel extrusion and batching mechanism, comprising two storage barrels, the outer walls of the two storage barrels are commonly fixed with a connecting plate, the upper side wall of each storage barrel is fixed with a hydraulic cylinder, the driving end of the hydraulic cylinder is located in the storage barrel and is fixedly connected with a piston plate matching the storage barrel, the lower side wall of each storage barrel is connected with a discharge end, a discharge channel is opened in the discharge end, a mounting rod is fixedly embedded at the lower end of the discharge channel, a piezoelectric ceramic sheet is fixedly embedded at the upper end of the mounting rod, and a A discharging inclined tube, a baffle is slidably inserted on the discharging flow channel, the baffle is provided with a discharging port, the outer wall of the baffle is fixedly connected with a tooth plate 1, a ratchet engaged with the tooth plate 1 is installed in the discharging end, and ratchet teeth for limiting the ratchet are installed in the discharging end, the outer wall of the discharging end is fixedly connected with two symmetrically arranged connecting ends, a capsule tube is fixedly connected between the two connecting ends, the capsule tube is filled with electrorheological fluid, the end of the baffle extends through and extends to the outside of the discharging end and contacts with the outer wall of the capsule tube, and the piezoelectric ceramic sheet and the electrorheological fluid located on the same discharging end are connected by a wire.

[0007] In the above-mentioned two-color latex tube annular barrel extrusion and dosing mechanism, a wire wheel is installed in the discharge end, a connecting rope is wound around the wire wheel, a guide tube is fixed in the discharge end, a right-angle rod is slidably inserted in the guide tube, a magnet plate is fixed at the end of the right-angle rod, the two ends of the connecting rope are respectively fixedly connected to the magnet plate and the outer wall of the ratchet, and an electromagnet located on the right side of the magnet plate is fixed in the discharge end.

[0008] In the above-mentioned two-color latex tube annular barrel extrusion and dispensing mechanism, a cavity is opened in the connecting plate, and an impact rod in contact with the outer walls of two storage barrels is slidably inserted on the outer wall of the connecting plate. A motor is fixed in the cavity, and an incomplete gear is fixedly connected to the outer wall of the driving end of the motor. A gear meshing with the incomplete gear is installed in the cavity, and a guide rod is fixedly connected to the inner wall of the cavity. The end of the guide rod is slidably sleeved with two toothed plates meshing with the incomplete gear and the gear. A reset spring is fixedly connected between the ends of the two impact rods and the inner wall of the cavity, and a push plate is fixedly connected to the outer wall of the gear. The outer walls of the two impact rods are integrally formed with protrusions, and the two ends of the push plate are located on the outside of the two protrusions.

[0012] The hydraulic cylinder is started to extrude the raw material to flow downward, and the ratchet is driven to rotate by the driving member, and the ratchet drives the tooth plate to move to the right, and the discharge port begins to communicate with the discharge channel, and the raw material in the discharge channel flows downward from the discharge port. After the raw material contacts the piezoelectric ceramic sheet, the piezoelectric ceramic sheet is squeezed to deform, and a voltage signal is output through the wire. Under the action of the voltage signal, the electrorheological fluid begins to change from liquid to solid. With the change of the connection area between the discharge port and the discharge channel, the discharge volume per unit time changes, and the pressure in contact with the piezoelectric ceramic sheet changes. When the voltage signal generated by the pressure squeezing the piezoelectric ceramic sheet completely transforms the electrorheological fluid into a solid, the capsule tube is solid as a whole and cannot undergo its own stretching change, that is, the baffle is limited, and the baffle cannot move. At the same time, the ratchet limits the ratchet to prevent it from rotating forward, and the baffle cannot move back, so that the connection area between the discharge port and the discharge channel is fixed, that is, the pressure is constant.

[0013] In summary, the present invention converts the pressure on the end of the discharge inclined tube when the raw material flows out into a voltage signal, and the voltage signal causes the electrorheological fluid to be converted into a solid, so that the shape of the capsule tube no longer changes, the area connected between the discharge port and the discharge channel no longer changes, and the pressure at the end of the discharge inclined tube is constant, thereby ensuring the constancy of the raw material pressure.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0021] Reference Figure 1-4A two-color latex tube annular barrel extrusion and batching mechanism comprises two storage barrels 1, the outer walls of the two storage barrels 1 are fixed with a connecting plate 2, the upper side wall of each storage barrel 1 is fixed with a hydraulic cylinder 3, the driving end of the hydraulic cylinder 3 is located in the storage barrel 1 and is fixedly connected with a piston plate matching the storage barrel 1, a cavity is opened in the connecting plate 2, and a collision rod 30 contacting the outer walls of the two storage barrels 1 is slidably inserted on the outer wall of the connecting plate 2, a motor 24 is fixed in the cavity, an incomplete gear 25 is fixedly connected to the outer wall of the driving end of the motor 24, a gear 26 meshing with the incomplete gear 25 is installed in the cavity, a guide rod 27 is fixedly connected to the inner wall of the cavity, and a toothed plate 28 meshing with the incomplete gear 25 and the gear 26 is slidably sleeved on the end of the guide rod 27, and a return spring 1 is fixedly connected between the ends of the two collision rods 30 and the inner wall of the cavity. 0, a push plate 29 is fixedly connected to the outer wall of the gear 26, and a protrusion 31 is integrally formed on the outer walls of the two impact rods 30. The two ends of the push plate 29 are located on the outside of the two protrusions 31. The starting motor 24 drives the incomplete gear 25 to rotate. When the incomplete gear 25 is engaged with the gear 26, it drives the tooth plate 28 to move toward the side of the guide rod 27. The tooth plate 28 drives the gear 26 to reverse, and the push plate 29 pushes the protrusion 31 on the right to move toward the side of the return spring 10. When the incomplete gear 25 rotates to engage with the gear 25, the push plate 29 pushes the protrusion 31 on the left, that is, the impact rod 30, to move toward the side of the return spring 10. The impact rod 30 on the right bounces up and hits the storage barrel 1 under the reverse elastic force of the return spring 10, causing the storage barrel 1 to vibrate, so that the raw materials in the storage barrel 1 are evenly distributed, ensuring the pressure balance of subsequent raw material extrusion, and avoiding the existence of pressure error points.

[0022] The lower side wall of each storage barrel 1 is connected to a discharge end 4, a discharge channel 20 is provided in the discharge end 4, a mounting rod 6 is fixedly embedded in the lower end of the discharge channel 20, a piezoelectric ceramic sheet 12 is fixedly embedded in the upper end of the mounting rod 6, a discharge inclined pipe 7 is connected to the outer wall of the discharge channel 20, a baffle 13 is slidably inserted in the discharge channel 20, a discharge port 23 is provided in the baffle 13, a tooth plate 14 is fixedly connected to the outer wall of the baffle 13, a ratchet 15 meshing with the tooth plate 14 is installed in the discharge end 4, and a rotating rod and a ratchet 15 are installed on the outer wall of the discharge end 4. A driving member 5 is connected, and the driving member 5 includes but is not limited to a motor or a handle, and the ratchet 15 is driven to rotate by the driving member 5. A ratchet 16 for limiting the ratchet 15 is installed in the discharge end 4. The outer wall of the discharge end 4 is fixedly connected to two symmetrically arranged connection ends 8, and a capsule tube 9 is fixedly connected between the two connection ends 8. The capsule tube 9 is filled with electrorheological fluid. The end of the baffle 13 extends through the outside of the discharge end 4 and contacts the outer wall of the capsule tube 9. The piezoelectric ceramic sheet 12 located on the same discharge end 4 is connected to the electrorheological fluid through a wire 11. At the beginning, the discharge port 23 and the discharge channel 20 are in a completely staggered state. At this time, no raw material is discharged. The hydraulic cylinder 3 is started to squeeze the raw material to flow downward, and the ratchet 15 is driven to rotate by the driving member 5. The ratchet 15 drives the tooth plate 14 to move to the right, and the discharge port 23 begins to communicate with the discharge channel 20. The raw material in the discharge channel 20 flows downward from the discharge port 23. After the raw material contacts the piezoelectric ceramic sheet 12, the piezoelectric ceramic sheet 12 is squeezed and deformed, and a voltage signal is output through the wire 11. Under the action of the voltage signal, the electrorheological fluid begins to change from liquid to solid. As the discharge port 23 changes in the area connected with the discharge channel 20, the discharge volume per unit time changes, and the pressure change in contact with the piezoelectric ceramic sheet 12. When the voltage signal generated by the pressure squeezing the piezoelectric ceramic sheet 12 completely transforms the electrorheological fluid into a solid, the capsule tube 9 is solid as a whole and cannot undergo its own stretching changes, that is, the baffle 13 is limited, and the baffle 13 cannot move. At the same time, the ratchet 16 limits the ratchet wheel 15 to prevent it from rotating forward, and the baffle 13 cannot move back, thereby fixing the area connected with the discharge port 23 and the discharge channel 20, thereby ensuring the constant pressure.

[0023] A wire wheel 21 is installed in the discharge end 4, and a connecting rope 22 is wound around the wire wheel 21. A guide tube 19 is fixed in the discharge end 4, and a right-angle rod is slidably inserted in the guide tube 19. A magnet plate 18 is fixed to the end of the right-angle rod. The two ends of the connecting rope 22 are respectively fixedly connected to the magnet plate 18 and the outer wall of the ratchet 16. An electromagnet 17 located on the right side of the magnet plate 18 is fixed in the discharge end 4. When the baffle 13 is subsequently released from the fixed state of rotation, the electromagnet 17 can be energized to adsorb the magnet plate 18 and move it to the side of the electromagnet 17. The ratchet 16 is pulled upward and rotated to disengage from the ratchet 15 by the connecting rope 22. At this time, the ratchet 15 can be driven to reverse through the driving member 5, and the baffle 13 moves back to close the discharge port 23 to stop discharging.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
