[0037] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0038] Reference below Figures 3 to 8 The pressure spraying mechanism according to the embodiment of the utility model is described.

[0039] like Figures 3 to 7As shown, a pressure spraying mechanism according to an embodiment of the utility model is used to drive the bottle body 910 and the nozzle 920 of the loading bottle 900 to move relative to each other. The pressure spraying mechanism includes: a mounting frame 100, a fixing mechanism and a pushing mechanism. The fixing mechanism is arranged on the mounting frame 100, and is used to fix the nozzle 920; the pushing mechanism includes a rotating drive mechanism 310 arranged on the mounting frame 100 and a pressing member 320 deviating from the rotating axis of the rotating drive mechanism 310. The rotating drive mechanism 310 can drive the pressing member 320 to rotate around the rotating axis of the rotating drive mechanism 310, and the pressing member 320 can rotate to press the lower end surface of the bottle body 910 to drive the bottle body 910 to move relative to the nozzle 920.

[0040] During operation, the eccentric rotation of the pressing piece 320 is utilized. When the pressing piece 320 rotates to press the lower end surface of the bottle body 910, since the nozzle 920 is fixed by the fixing mechanism, the pressing piece 320 presses the bottle body 910 to move toward the nozzle 920, so that the bottle body 910 and the nozzle 920 move relatively close to each other, thereby pushing the nozzle 920, and spraying the liquid in the bottle body 910 to meet the requirements of pressure spraying. Since the nozzle 920 is fixed to the mounting frame 100, during the pressure spraying process, the nozzle 920 rarely moves relative to the mounting frame 100, thereby improving the stability and reliability of the carrier bottle spraying.

[0041] Specifically, the mounting frame 100 can be a door body, a cabinet body, etc., and the mounting frame 100 is provided with a corresponding injection port, and the nozzle 920 is connected to the injection port through the pipe 921 or directly connected to the injection port. Since the nozzle 920 is fixed to the mounting frame 100, during the pressure spraying process, the pressure spraying mechanism of the utility model has less movement of the nozzle 920 relative to the mounting frame 100, thereby reducing the deformation of the pipe or reducing the deviation of the nozzle 920 from the injection port. The pipe is less likely to detach or spray deviate, thereby improving the stability and reliability of the carrier bottle injection.

[0042] In some embodiments of the utility model, the pushing mechanism adopts a rotating drive mechanism 310 in cooperation with an eccentric pressing member 320 to press the bottle body 910 to move, which can have a large pushing force, ensure that the pressure spraying can proceed normally, and is easy to control and can meet the automation requirements.

[0043] Specifically, the driving unit of the rotating drive mechanism 310 can be a motor, a rotary cylinder, etc. The rotating drive mechanism 310 can also be configured with a corresponding reduction mechanism, such as a circular gear set reducer, a planetary gear reducer, etc. By using an eccentrically arranged pressing piece 320, the pressing piece 320 can be switched between a pressing position and a non-pressing position by controlling the rotation angle.

[0044] like Figure 5 , Figure 7As shown, in some embodiments of the present invention, the pushing mechanism also includes a turntable 330, which is connected to the output shaft of the rotating drive mechanism 310. The pressing member 320 is arranged at a position where the turntable 330 deviates from the rotation axis of the rotating drive mechanism 310. When the turntable 330 is driven to rotate, it can drive the pressing member 320 to revolve around the rotation axis of the rotating drive mechanism 310, so that it can switch between a pressing position and a non-pressing position.

[0045] It is conceivable that in some embodiments of the present invention, the pressing member 320 may be an eccentric or raised portion of an eccentric wheel or a cam, and the eccentric wheel or the cam is connected to the output shaft of the rotating drive mechanism 310. The rotating drive mechanism 310 drives the eccentric wheel or the cam, and the eccentric or raised portion can also be used to press the bottle body 910.

[0046] In some embodiments of the present invention, the pressing member 320 can be rotatably disposed on the turntable 330 to reduce the friction between the pressing member 320 and the lower end surface of the bottle body 910 when the pressing member 320 rotates and moves, thereby reducing the situation where the bottle body 910 is driven to rotate.

[0047] Specifically, when the pressing piece 320 presses against the lower end surface of the bottle body 910, the pressing piece 320 is in a moving state, and the pressing piece 320 moves through the lower end surface of the bottle body 910 and maintains the pressure. The pressing piece 320 is set to be rotatable (rotate) to reduce the situation where the pressing piece 320 drives the bottle body 910 to rotate, and reduces the situation where the bottle body 910 and the nozzle 920 are loosened / detached.

[0048] It is conceivable that in some embodiments of the present invention, after the rotating shaft is set on the rotating disk 330, the pressing member 320 is rotatably set on the rotating shaft, which can meet the requirement that the pressing member 320 can be rotatably set (rotated).

[0049] It is understandable that in some embodiments of the present invention, the rotating shaft may be fixedly arranged on the top pressure piece 320, and the rotating shaft may be rotatably installed on the turntable 330, which may also meet the requirement that the top pressure piece 320 may be rotatable (rotatable).

[0050] In some embodiments of the present invention, the pressing member 320 is a rubber roller.

[0051] like Figures 3 to 7As shown, in some embodiments of the utility model, the nozzle 920 is provided with a clamping portion 922, and the fixing mechanism includes a top plate 210 fixed to the mounting frame 100, a pressure plate 220 movably arranged under the top plate 210, and a fastening mechanism capable of driving the pressure plate 220 to move relative to the top plate 210, and a clamping space in which the clamping portion 922 can be installed is formed between the top plate 210 and the pressure plate 220, and the fastening mechanism drives the pressure plate 220 to move relative to the top plate 210 to clamp the clamping portion 922 located in the clamping space, thereby meeting the fixing requirements of the nozzle 920.

[0052] Specifically, in this embodiment, the nozzle 920 is provided with a clamping portion 922, and the top plate 210 and the pressing plate 220 are distributed up and down, and the clamping portion is inserted between the top plate 210 and the pressing plate 220. The fastening mechanism makes the top plate 210 and the pressing plate 220 move relative to each other, thereby clamping the nozzle 920.

[0053] It can be understood that in some embodiments of the present invention, the fixing mechanism can also achieve the clamping and fixing requirements by clamping other positions of the nozzle 920, such as distributing the two clamping arms to the left and right, and meeting the fixing requirements of the nozzle 920 by clamping the circular body of the nozzle 920.

[0054] In some embodiments of the present invention, the cross section of the pressing plate 220 is in the shape of a groove opening downwards, so as to match the upper end of the spray head 920 and have a certain positioning effect on the spray head 920 .

[0055] In some embodiments of the present invention, the top plate 210 and the pressing plate 220 are both sheet metal parts, which can be directly formed by a stamping process, with low production cost and convenient production and processing.

[0056] like Figure 5 , Figure 6 , Figure 7 As shown, in some embodiments of the utility model, the fastening mechanism includes a fastening screw 231 and a fastening nut 232 cooperating with the fastening screw 231. The fastening screw 231 is arranged on the pressure plate 220 and extends upward. The top plate 210 is provided with a fastening hole 211 for the fastening screw 231 to pass through. The fastening nut 232 is located above the top plate 210. By tightening or loosening the fastening nut 232, the distance between the top plate 210 and the pressure plate 220 can be adjusted to facilitate clamping the nozzle 920, or loosening the nozzle 920 to facilitate replacement of the loading bottle 900.

[0057] Specifically, one end of the fastening screw 231 is fixed to the pressure plate 220 by welding or a double-nut fastening structure, and the other end of the fastening screw 231 extends upward and passes through the fastening hole 211 and is connected to the fastening nut 232. When the fastening nut 232 is tightened, the pressure plate 220 can be driven to move upward, thereby clamping the nozzle 920. When the fastening nut 232 is loosened in the opposite direction, the pressure plate 220 can move downward due to its own gravity or the gravity of the loading bottle 900, thereby facilitating the replacement of the loading bottle 900 and enabling rapid replacement of the loading bottle 900.

[0058] It can be understood that in some embodiments of the present invention, a screw rod may also be configured to pass through the through holes of the top plate 210 and the pressure plate 220 respectively, and nuts may be configured at both ends of the screw rod. By tightening or loosening a single or two nuts, the distance between the top plate 210 and the pressure plate 220 may also be adjusted.

[0059] like Figure 5 As shown, in some embodiments of the present invention, the top plate 210 and the pressing plate 220 are respectively provided with notches corresponding to the spray head 920 to facilitate positioning of the spray head 920 or to facilitate installation of the spray head 920 .

[0060] In some embodiments of the present invention, the fastening hole 211 is a waist-shaped hole to facilitate the relative position adjustment of the top plate 210 and the pressure plate 220, and the position of the nozzle 920 can be easily adjusted to better align it with the injection port.

[0061] Specifically, the notch on the pressing plate 220 can cooperate with the nozzle 920 to position the nozzle 920. By setting the fastening hole 211 as a waist-shaped hole, the position of the nozzle 920 can be fine-tuned to align it with the injection port.

[0062] In some embodiments of the present invention, the fastening nut 232 is a butterfly nut, which facilitates the rotation of the fastening nut 232 .

[0063] like Figure 3 As shown, in some embodiments of the utility model, the top plate 210 is installed to the mounting frame 100 by a bolt mechanism, and the bolt mechanism includes a mounting screw (not shown in the figure) provided on the mounting frame 100 and a mounting nut (not shown in the figure) cooperating with the mounting screw. The top plate 210 is provided with a mounting hole 212 for the mounting screw to pass through. The top plate 210 is installed and fixed to the mounting frame 100 by cooperating with the mounting screw, the mounting hole 212 and the mounting nut, and the top plate 210 can be removed as needed for easy maintenance.

[0064] like Figure 3 As shown, in some embodiments of the present invention, the mounting hole 212 is a U-shaped hole or a waist-shaped hole extending in the up-down direction to facilitate the adjustment of the height of the top plate 210 to accommodate carrier bottles 900 of different specifications.

[0065] It is understandable that in some embodiments of the present invention, the top plate 210 may also be fixed to the mounting frame 100 by welding, riveting, etc., which will not be described in detail herein.

[0066] In some embodiments of the present invention, the pressure spraying mechanism further includes a guiding mechanism, which is disposed on the mounting frame 100 and is used to guide the bottle body 910 to move up and down, thereby reducing the deviation of the bottle body 910 and improving the reliability of the pressure spraying mechanism.

[0067] like Figures 3 to 7 As shown, in some embodiments of the utility model, the guide mechanism includes a first guide plate 410 provided on the mounting frame 100 and a second guide plate 420 detachably installed on the first guide plate 410 or the mounting frame 100, the first guide plate 410 is provided with a first guide hole 411, and one side of the first guide hole 411 is a first opening structure for the bottle body 910 to be loaded, and the second guide plate 420 can cover the first opening structure when installed on the first guide plate 410 or the mounting frame 100, thereby forming a guide hole structure corresponding to the bottle body 910.

[0068] Specifically, the first guide hole 411 is a U-shaped hole, one side of which is a first opening structure. The bottle body 910 can be laterally inserted into the first guide hole 411, and finally the second guide plate 420 is installed to the first guide plate 410 or the mounting frame 100 to block the first opening structure of the first guide hole 411, thereby limiting the movement of the bottle body 910 in the left and right, front and back directions, and forming a guide space to guide the bottle body 910 to move up and down.

[0069] It is conceivable that in some embodiments of the present invention, a guide cylinder corresponding to the bottle body 910 may be provided on the mounting frame 100 , and the guide cylinder extends in the up-down direction, which may also achieve a guiding effect of guiding the bottle body 910 to move up and down.

[0070] In some embodiments of the present invention, the first guide plate 410 can be fixedly mounted to the mounting frame 100 by means of auxiliary brackets, welding, riveting or threaded connection.

[0071] like Figure 6 As shown, in some embodiments of the utility model, the second guide plate 420 is provided with a second guide hole 421, and one side of the second guide hole 421 is a second opening structure for the bottle body 910 to be loaded, and the first opening structure and the second opening structure have different orientations. The second guide hole 421 further improves the guiding effect of the guiding mechanism, and the first opening structure and the second opening structure have different orientations. The first guide hole 411 and the second guide hole 421 can form a staggered or reverse layout to improve the guiding effect.

[0072] Specifically, the second guide hole 421 is a U-shaped hole, one side of which is an open structure, so that the second guide plate 420 can be inserted laterally and the bottle body 910 can be placed in the second guide hole 421 to achieve guiding and positioning of the bottle body 910. The first guide hole 411 and the second guide hole 421 are U-shaped holes respectively, and are staggered or reversely arranged, so that the bottom circular parts of the two U-shaped holes can complement each other, forming a better positioning space and improving the guiding effect.

[0073] like Figure 6 As shown, in some embodiments of the present invention, the first opening structure and the second opening structure are oriented in opposite directions, and the first guide hole 411 and the second guide hole 421 are U-shaped holes respectively, and are arranged in reverse so that the bottom semicircles of the two U-shaped holes can complement each other to form a circular positioning space roughly corresponding to the bottle body 910.

[0074] like Figure 4 and Figure 7 As shown, in some embodiments of the present invention, the second guide hole 421 is located below the first guide hole 411 and has a set spacing distance from the first guide hole 411, forming a double-layer positioning with upper and lower spacing distribution, thereby improving the guiding effect.

[0075] Specifically, during implementation, the set interval distance between the first guide hole 411 and the second guide hole 421 can be set as needed, such as 1 cm, 2 cm, 3 cm, etc.

[0076] In some embodiments of the present invention, the second guide plate 420 is configured as an L-shaped structure, the upper portion of which is connected to the first guide plate 410 , and the lower transverse plate is provided with a second guide hole 421 , thereby forming a gap between the second guide hole 421 and the first guide hole 411 .

[0077] like Figure 5 and Figure 6 As shown, in some embodiments of the utility model, the second guide plate 420 is detachably mounted on the first guide plate 410, the first guide plate 410 is provided with a disassembly screw 431, the disassembly screw 431 is provided with a disassembly nut 433, the second guide plate 420 is provided with a disassembly hole 432 for the disassembly screw 431 to pass through, the disassembly screw 431 is connected with the disassembly nut 433 after passing through the disassembly hole 432, after unscrewing the disassembly nut 433, the second guide plate 420 can be easily removed, the loading bottle 900 is convenient to be taken and placed, and the loading bottle 900 can be quickly replaced.

[0078] It is understandable that, in some embodiments of the present invention, the second guide plate 420 can also be detachably mounted on the first guide plate 410 via a snap mechanism.

[0079] It is conceivable that in some embodiments of the present invention, the second guide plate 420 can be detachably mounted on the mounting frame 100 as needed, such as detachably mounted by screws or a snap mechanism.

[0080] like Figure 5 and Figure 6 As shown, in some embodiments of the present invention, the disassembly hole 432 is a waist-shaped hole to facilitate adjustment of the position of the second guide plate 420 .

[0081] Specifically, the disassembly hole 432 is a waist-shaped hole extending laterally (left and right) to facilitate adjustment of the left and right position of the second guide plate 420 so that the second guide hole 421 can be roughly aligned with the first guide hole 411 to ensure the guiding effect.

[0082] In some embodiments of the present invention, the disassembly nut 433 is a butterfly nut, which facilitates the rotation of the disassembly nut 433 .

[0083] like Figures 3 to 7 As shown, in some embodiments of the present invention, the second guide plate 420 is detachably provided with a support plate 440 , and the support plate 440 includes a supporting portion 441 located below the bottle body 910 to support the bottle body 910 and improve the stability of the bottle body 910 when placed.

[0084] Specifically, the supporting portion 441 can support the bottle body 910 , reduce the gravity of the bottle body 910 acting on the spray head 920 , and reduce the occurrence of deformation and displacement of the spray head 920 .

[0085] In some embodiments of the present invention, the supporting portion 441 avoids the portion of the lower end surface of the bottle body 910 that is used to contact the pressing member 320 , so as to avoid affecting the pressing member 320 from pressing and driving the bottle body 910 .

[0086] Specifically, the supporting portion 441 contacts a portion of the lower end surface of the bottle body 910 , and the portion not contacting the supporting portion 441 corresponds to the pressing member 320 , so as to be in pressing contact with the pressing member 320 .

[0087] In some embodiments of the present invention, the support plate 440 is an L-shaped structure, the upper portion of which is connected to the second guide plate 420 , and the lower transverse plate forms a supporting portion 441 .

[0088] like Figure 5 and Figure 6As shown, in some embodiments of the utility model, the second guide plate 420 is provided with a threaded hole 422, and the support plate 440 is provided with a through hole 442 corresponding to the threaded hole 422. The threaded hole 422 is provided with a disassembly screw 423. The disassembly screw 423 passes through the through hole 442 and is connected to the threaded hole 422 to install the support plate 440 to the second guide plate 420. After unscrewing the disassembly screw 423, the support plate 440 can be removed to facilitate the replacement of the loading bottle 900.

[0089] It is understandable that in some embodiments of the present invention, a screw rod extending outward may be provided on the second guide plate 420 and a corresponding locking nut may be configured to meet the requirements for disassembling and assembling the support plate 440 .

[0090] like Figure 5 and Figure 6 As shown, in some embodiments of the present invention, the through hole 442 is a waist-shaped hole to facilitate adjustment of the position of the support plate 440 .

[0091] Specifically, the through hole 442 is a waist-shaped hole and extends in the up and down directions. After loosening the disassembly screw 423, the position of the supporting part 441 can be adjusted up and down so that it can match with the loading bottles 900 of different specifications to ensure its supporting effect. After adjusting to the set position, tighten the disassembly screw 423 to fix the position of the support plate 440.
