[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] An epoxy rebar connecting sleeve spraying device for bridge construction, such as Figures 1 to 3 As shown, the device includes a frame 1 and a support 2. One end of the support 2 is rotatably mounted on the frame 1, and the other end is provided with a receiving groove 3 for accommodating a connecting sleeve 16. An external spraying mechanism is provided on one side of the frame 1 at a position above the receiving groove 3, and a feed port is provided on the other side to facilitate the connection sleeve 16 entering the receiving groove 3. The receiving groove 3 has an opening at one end facing the feed port. An internal spraying mechanism and a drive mechanism for driving the connection sleeve 16 to rotate and move are provided on the support 2 at a position corresponding to the receiving groove 3.

[0022] In practical applications, this spraying device can be used in conjunction with a feeding and unloading conveyor for the connecting sleeve 16. For example, a conveyor belt is used to first feed the connecting sleeve 16 to be sprayed into the receiving tank 3 through the inlet and outlet, and the carrier 2 is rotated so that the opening of the receiving tank 3 is aligned with the unloading conveyor. Then, the inner and outer sides of the connecting sleeve 16 can be sprayed simultaneously using the outer and inner spraying mechanisms. During the spraying process, the drive mechanism is used to rotate and move the connecting sleeve 16 to improve the uniformity of the spraying. At this time, the connecting sleeve 16 is gradually moved out of the receiving tank 3 while being sprayed. The sprayed connecting sleeve 16 can finally be collected by the unloading conveyor, thus completing the spraying process of one connecting sleeve 16. Similarly, by driving the carrier 2 to rotate and reset after the spraying of one connecting sleeve 16, continuous spraying of a batch of connecting sleeves 16 can be achieved, which is beneficial to improving the spraying efficiency of a batch of connecting sleeves 16.

[0023] Preferably, the internal spraying mechanism includes a liquid supply pipe 4 and an internal nozzle 6. The length direction of the liquid supply pipe 4 is the same as the length direction of the receiving tank 3. One end of the liquid supply pipe 4 that extends into the receiving tank 3 is provided with a downwardly bent portion 10, and the other end is provided on a support seat 2. The internal nozzle 6 is provided on the liquid supply pipe 4.

[0024] For example, the liquid supply pipe 4 can be fixed to the support 2, and the inner nozzle 6 can be fixedly or detachably installed on the liquid supply pipe 4. For example, the inner nozzle 6 and the liquid supply pipe 4 can be connected by threads to facilitate the replacement and maintenance of the inner nozzle 6. In addition, those skilled in the art can also choose a suitable method to install the liquid supply pipe 4 and the inner nozzle 6 according to actual needs, so as to achieve the liquid supply pipe 4 to supply liquid to the inner nozzle 6, which will not be elaborated here.

[0025] In practical applications, the bend 10 on the liquid supply pipe 4 can effectively guide the connecting sleeve 16 as it extends into the receiving groove 3. The inner side of the connecting sleeve 16 can be lifted upward along the bend 10 by contacting the bend 10. This not only allows the liquid supply pipe 4 to easily extend into the connecting sleeve 16, but also allows the connecting sleeve 16 to stably cooperate with the drive mechanism by lifting the connecting sleeve 16, making it easier for the subsequent drive mechanism to drive the connecting sleeve 16 to rotate and move.

[0026] Optionally, one end of the bent portion 10 is mounted on the liquid supply pipe 4, and the other end extends out of the receiving groove 3. By extending the bent portion 10 out of the receiving groove 3, the bent portion 10 can better guide the connecting sleeve 16. When the connecting sleeve 16 has not entered the receiving groove 3, the bent portion 10 can lift the end of the connecting sleeve 16, avoiding jamming caused by the connecting sleeve 16 contacting the edge of the receiving groove 3, and improving the stability during continuous feeding.

[0027] Optionally, one end of the inner nozzle 6 is connected to the liquid supply pipe 4, and the other end is positioned towards the mating gap. Specifically, the mating gap is connected to the receiving tank 3, and a waste liquid collection pipe 12 connected to the mating gap is provided below the support base 2. In actual use, the waste liquid collection pipe 12 is fixed on the support base 2 and can be connected to the collection box (not shown in the figure) through a flexible hose with redundant length, so as to facilitate the collection of waste liquid and reduce the pollution of waste liquid to the environment.

[0028] In practical applications, by setting the inner nozzle 6 toward the mating gap, the inner nozzle 6 can not only play a good role in spraying the inner side of the connecting sleeve 16, which is conducive to further improving the uniformity of the overall spraying of the connecting sleeve 16; but also the paint residue left by the inner nozzle 6 during or after spraying can drip into the mating gap and finally be collected and discharged through the waste liquid collection pipe 12.

[0029] Optionally, the support 2 is provided with a beveled portion 9 at the position corresponding to the opening of the receiving groove 3 to guide the connecting sleeve 16 into the receiving groove 3. Specifically, the left and right side walls and the bottom surface of the receiving groove 3 can be provided with beveled portions 9, and a funnel-shaped opening is formed at the end of the receiving groove 3. This can further reduce the possibility of the connecting sleeve 16 getting stuck when entering the receiving groove 3. Combined with the lifting effect of the bending portion 10 on the end of the connecting sleeve 16, it helps to improve the stability and reliability of this spraying device during continuous spraying operations.

[0030] Preferably, the driving mechanism includes two driving rollers 11 arranged on the left and right sides of the support seat 2, with a fitting gap between the two driving rollers 11 that cooperates with the connecting sleeve 16. Each driving roller 11 is rotatably mounted on the support seat 2, and the length direction of each driving roller 11 is the same as the length direction of the liquid supply pipe 4. The support seat 2 is provided with a driver for driving the driving roller 11 to rotate. The driving roller 11 is provided with a spiral protrusion 17 that can cooperate with the outer surface of the connecting sleeve 16.

[0031] For example, the drive roller 11 can be mounted on the support base 2 by conventional means such as a rotating shaft. The support base 2 has a shaft hole or bearing seat that mates with the rotating shaft at the position corresponding to the receiving groove 3. With two drive rollers 11 arranged on the left and right sides of the support base 2, the two drive rollers 11 can stably support the connecting sleeve 16 and prevent the connecting sleeve 16 from falling off during rotation and movement. At the same time, by providing helical protrusions 17 on the surface of the drive roller 11, the drive roller 11 can provide not only the main force for axial rotation of the connecting sleeve 16, but also the secondary force for axial movement of the connecting sleeve 16 through frictional engagement between the helical protrusions 17 and the outer surface of the connecting sleeve 16. This allows the connecting sleeve 16 to rotate and slowly move towards the opening of the receiving groove 3, so that the inner and outer spraying mechanisms can evenly spray the inner and outer sides of the connecting sleeve 16.

[0032] It should be noted that the operator can adjust the density of the spiral protrusions 17 and the coefficient of friction between the spiral protrusions 17 and the connecting sleeve 16 as needed to ensure that the connecting sleeve 16 can complete a full circle of spraying during rotation. This will not be elaborated further here.

[0033] In practical applications, the driver uses a drive motor 20, the output end of which is equipped with a drive gear 19. Each of the two drive rollers 11 has a driven gear 18 that meshes with the drive gear 19, and the spiral protrusions 17 on the two drive rollers 11 rotate in opposite directions. The installation and power supply methods of the drive motor 20 are existing technologies and will not be described in detail here.

[0034] Specifically, the driven gear 18 can be fixed on the rotating shaft of the drive roller 11, and the drive gear 19 can be fixed on the output shaft of the drive motor 20. By cooperating with one drive gear 19 and two driven gears 18, one driver can drive the two drive rollers 11 to rotate, making the structure simpler. It should be noted that since the two drive rollers 11 rotate in opposite directions under the drive of one drive gear 19, in order to ensure that the helical protrusions 17 on the two drive gears 19 can jointly push the connecting sleeve 16 to move, the helical protrusions 17 on the two drive rollers 11 need to be set in opposite directions. Those skilled in the art can adjust the direction of rotation of the helical protrusions 17 according to the rotation direction of the drive rollers 11 so that when the drive rollers 11 rotate, the helical protrusions 17 can exert a force on the connecting sleeve 16 to move it toward the opening of the receiving groove 3.

[0035] Preferably, the liquid supply pipe 4 and the support base 2 are connected by a reinforcing plate 5. For example, one end of the reinforcing plate is fixed to the liquid supply pipe 4, and the other end is fixed to the support base 2. In actual use, by using the reinforcing plate 5 to structurally strengthen the connection between the liquid supply pipe 4 and the support base 2, the structural strength and stability of the liquid supply pipe 4 are improved. This ensures that the bend 10 on the liquid supply pipe 4 can effectively lift the end of the connecting sleeve 16, and also ensures that the spacing between the inner spray nozzle and the inner wall of the connecting sleeve 16 remains consistent, which helps improve the uniformity of the inner nozzle 6 spraying.

[0036] Preferably, the support base 2 is rotatably mounted on the frame 1 via a rotating shaft 15, and the frame 1 is equipped with a servo motor 14 for driving the rotating shaft 15 to rotate. The installation and power supply methods of the servo motor 14 are existing technologies, and therefore will not be described in detail here.

[0037] For example, the rotating shaft 15 is fixed on the bearing seat 2. The output end of the servo motor 14 can be connected to the rotating shaft 15 via a coupling. A shaft hole or bearing seat that mates with the rotating shaft 15 can be installed on the frame 1. By using the servo motor 14 to drive the bearing seat 2 to rotate, the rotation accuracy of the bearing seat 2 is improved, making it easier for the bearing seat 2 to be used in conjunction with the feeding and unloading conveying equipment of the connecting sleeve 16. In addition, those skilled in the art can also choose other suitable methods to connect the servo motor 14 and the rotating shaft 15 according to actual needs, so as to drive the rotating shaft 15 to drive the bearing seat 2 to rotate. These will not be elaborated here.

[0038] Preferably, the external spraying mechanism includes an infusion tube 7 and an external nozzle 8. The infusion tube 7 is mounted on the frame 1, and the external nozzle 8 is mounted on the infusion tube 7. Exemplarily, the infusion tube 7 can be fixed to the frame 1, and the external nozzle 8 can be fixedly or detachably mounted on the infusion tube 7. For example, the external nozzle 8 and the infusion tube 7 can be connected by threads to facilitate replacement and maintenance of the external nozzle 8. Furthermore, those skilled in the art can choose a suitable method to install the infusion tube 7 and the external nozzle 8 according to actual needs, so that the infusion tube 7 supplies liquid to the external nozzle 8; this will not be elaborated further here.

[0039] In practical applications, the spraying device also includes an external liquid supply device 21. Both the liquid supply pipe 4 and the liquid delivery pipe 7 are connected to the external liquid supply device 21 via a connecting hose 13. Specifically, the connecting hose 13 can be an existing rubber hose or corrugated hose, etc., and the external liquid supply device 21 can be a liquid supply pump, etc. The connecting hose 13 connected to the liquid supply pipe 4 needs to have a spare length to allow the support seat 2 to rotate. Those skilled in the art can also select other suitable external liquid supply devices 21 according to actual needs to achieve liquid supply to the liquid supply pipe 4 and the liquid delivery pipe 7, which will not be elaborated here.

It can be used for spraying epoxy rebar connecting sleeves, offering advantages such as good spray uniformity and high spraying efficiency. It can be used in conjunction with material feeding and conveying equipment to achieve continuous spraying of batch connecting sleeves. By setting a rotatable support seat on the frame and utilizing the receiving groove on the support seat to accommodate the connecting sleeves, and cooperating with the external spraying mechanism on the frame and the internal spraying mechanism on the support seat, synchronous spraying of the inner and outer sides of the connecting sleeves can be achieved. Furthermore, during the spraying process, a drive mechanism can be used to rotate and move the connecting sleeves to further improve spray uniformity. After spraying is completed, the connecting sleeves can be removed from the support seat.
