Description

Technical Field

[0001] The utility model relates to the technical field of decoration engineering tools, in particular to a glue spraying machine for decoration engineering. Background Art

[0002] Gluing in decoration engineering refers to the process of using tools to squeeze sealant out of the hose to seal, bond, fill seams or repair leaks. The most common glue application tool is a glue gun.

[0003] Application number 202020824278.1 provides a gluing device for decorative engineering, including a placement barrel, a nozzle, a driving device, a push rod and a push piece. The nozzle head is screwed on the right end of the placement barrel, and the nozzle is connected to the placement barrel. A placement opening is opened at the left end of the placement barrel, and a placement rack is arranged at the left end of the placement barrel. The placement rack is located on the left side of the placement opening. A fixing plate is arranged at the left end of the placement rack, and a through hole is opened at the left end of the fixing plate. The right end of the push rod extends from the left end of the through hole into the placement rack. Rectangular grooves are opened at the front and rear ends of the push rod, and transmission racks are arranged in the two sets of rectangular grooves. The push piece is installed at the right end of the push rod, and the driving device is installed on the left side of the placement rack.

[0004] The device uses a reduction motor to drive the shaft and the main gear to rotate, and through the meshing of the main gear and the transmission rack, drives the push rod to move to the right at a uniform speed, achieving uniform glue discharge and improving glue application efficiency. However, the device is not equipped with a pressure relief device and a locking device, and it is impossible to lock the push rod after the glue application is completed, and it is also impossible to release the pressure on the push rod. If the reduction motor can self-lock, the push rod cannot move to the left on its own, thereby always squeezing the rubber hose. Due to the delayed flow of the colloid, it will cause glue overflow. If the reduction motor cannot self-lock, the weight of the rubber hose itself will push the push rod to move to the left, thereby falling off the placement barrel. Utility Model Content

[0030] Embodiment 1:

[0031] See also Figure 1-5The utility model describes the above technical solution in detail through the following embodiments:

[0032] A glue spraying machine for decoration engineering, comprising:

[0033] The gluing device 1 comprises a handle 11 , a gluing rod 13 is slidably mounted on the top of the handle 11 through a guide ring 12 , the gluing rod 13 is used to squeeze the rubber tube, the gluing rod 13 is connected to a driving device 2 , and the driving device 2 is connected to a pressure release device 3 .

[0034] There are two guide rings 12 , both of which are made of metal. The axes of the two guide rings 12 coincide with each other, and the glue rod 13 passes through the centers of the two guide rings 12 .

[0035] A hose rack 15 is welded on the left side of the left guide ring 12, and the hose rack 15 is used for placing the sealant hose used for decoration engineering.

[0036] Tooth grooves 14 are provided on the left and right sides of the glue rod 13 .

[0037] The glue rod 13 is a solid metal rod, and the tooth grooves 14 are symmetrically located on the left and right sides of the glue rod 13. A metal disc is welded on the head of the glue rod 13 to squeeze the piston in the rubber hose.

[0038] The driving device 2 comprises a first motor 21, which is connected to a driven gear 25 through a gear transmission device, the driven gear 25 is connected to the glue rod 13, and the driven gear 25 is slidably connected to a mounting frame 26 through a transmission sleeve 28. The left tooth groove 14 meshes with the driven gear 25.

[0039] The driven gear 25 is clamped with the transmission sleeve 28, and the transmission sleeve 28 is a hollow metal tube. The transmission sleeve 28 is slidably connected with the mounting frame 26, and the mounting frame 26 is fixedly installed inside the handle 11 by screws. The first motor 21 can be a servo motor or a stepper motor. After the first motor 21 is started, it can drive the driven gear 25 to rotate through the gear transmission device, thereby driving the glue rod 13 to move.

[0040] The driving device 2 further comprises a clamping gear 27 , which is meshed with the right tooth groove 14 , and the clamping gear 27 is slidably connected to the mounting frame 26 via a transmission sleeve 28 .

[0041] The clamping gear 27 and the driven gear 25 are symmetrically located on the left and right sides of the glue-spreading rod 13. When the driven gear 25 drives the glue-spreading rod 13 to move, it can drive the clamping gear 27 to rotate.

[0042] The gear transmission device includes a bevel gear assembly 22, a worm gear assembly 23 and a reduction gear assembly 24.

[0043] The bevel gear assembly 22 is used to connect the worm gear assembly 23 and the output shaft of the first motor 21 , and can transmit the power of the first motor 21 to the worm gear assembly 23 .

[0044] The worm gear assembly 23 adopts a known worm gear and worm transmission device with self-locking capability.

[0045] The reduction gear assembly 24 is used to connect the worm gear assembly 23 and the left transmission sleeve 28. The reduction gear assembly 24 includes two gears, one large and one small, which mesh with each other. The small gear is fixedly connected to the worm gear through a rotating shaft, and the large gear is engaged with the transmission sleeve 28. The worm gear drives the small gear to rotate, thereby driving the large gear to rotate, thereby driving the transmission sleeve 28 to rotate, and the large gear is used to reduce the rotation speed and increase the torque.

[0046] The pressure release device 3 includes a reset device and a locking rod 31. The reset device is used to drive the transmission sleeve 28 to move toward the glue rod 13. The head of the locking rod 31 is slidably connected to the transmission sleeve 28. The locking rod 31 is used to limit the movement of the transmission sleeve 28. The locking rod 31 is connected to the locking device. The locking device is used to drive the locking rod 31 to move toward the transmission sleeve 28.

[0047] The head of the locking rod 31 is inserted into the transmission sleeve 28 to limit the movement of the transmission sleeve 28 .

[0048] The reset device includes a slider 36 , which is slidably mounted in the middle of the mounting frame 26 , the front side of the slider 36 is in contact with the transmission sleeve 28 , and a reset spring 37 is clamped between the rear side of the slider 36 and the mounting frame 26 .

[0049] The end faces of the return spring 37 are in contact with the mounting frame 26 and the slider 36 respectively. The elastic force of the return spring 37 can drive the slider 36 away from the mounting frame 26, thereby driving the transmission sleeve 28 to move toward the glue rod 13. Then, the clamping gear 27 and the driven gear 25 are driven to approach each other and mesh with the tooth groove 14.

[0050] The locking device includes a locking spring 32 , which is sleeved on the locking rod 31 and located inside the handle 11 . The head of the locking rod 31 passes through the top of the handle 11 and is threadedly connected with an adjusting nut 34 .

[0051] The elastic force of the locking spring 32 can drive the locking rod 31 to move downward, so that the heads of the locking rod 31 are inserted into the center of the transmission sleeve 28. By rotating the adjusting nut 34, the locking rod 31 can be driven to move up and down, and the length of the locking rod 31 inserted into the transmission sleeve 28 can be adjusted.

[0052] A connecting piece 33 is provided between the adjusting nut 34 and the top surface of the handle 11 , and an unlocking ring 35 is welded to the middle of the top surface of the connecting piece 33 .

[0053] The connecting piece 33 is penetrated by two locking rods 31 at the same time. Applying an upward pulling force to the unlocking ring 35 can drive the connecting piece 33 to move upward through the unlocking ring 35, thereby driving the locking rod 31 to move upward through the adjusting nut 34, so that the locking rod 31 is separated from the transmission sleeve 28, unlocking the transmission sleeve 28, and compressing the locking spring 32 at the same time.

[0054] The external force applied to the unlocking ring 35 is removed, and the elastic force of the locking spring 32 drives the locking rod 31 to move downward, and the connecting piece 33 is driven downward by the adjusting nut 34 until the bottom surface of the connecting piece 33 abuts against the top surface of the handle 11, and the locking rod 31 is reinserted into the transmission sleeve 28.

[0055] When using the device, the operator of this embodiment first puts the hose into the hose rack 15.

[0056] Start the first motor 21. The output shaft of the first motor 21 drives the worm of the worm gear assembly 23 to rotate through the bevel gear assembly 22, thereby driving the worm wheel to rotate. The worm gear assembly 23 drives the transmission sleeve 28 to rotate through the reduction gear assembly 24, thereby driving the driven gear 25 to rotate, and then drives the glue rod 13 to move toward the hose. The glue rod 13 drives the piston of the hose to move, thereby squeezing the colloid in the hose to achieve glue application.

[0057] After the gluing is completed, the unlocking ring 35 is pulled upwards, and the connecting piece 33 can be driven to move upwards through the unlocking ring 35, thereby driving the locking rod 31 to move upwards through the adjusting nut 34, so that the locking rod 31 is separated from the transmission sleeve 28.

[0058] The unreleased pressure in the colloid will drive the piston of the rubber hose to move backward, thereby driving the glue rod 13 to move backward, and the tooth groove 14 squeezes the driven gear 25 and the clamping gear 27 to both sides, thereby driving the driven gear 25 and the clamping gear 27 away from the glue rod 13.

[0059] The driven gear 25 and the clamping gear 27 move outward, and the return spring 37 can be compressed by the slider 36 .

[0060] After the pressure is released, the glue rod 13 stops moving. Under the elastic force of the return spring 37, the slider 36 drives the driven gear 25 and the clamping gear 27 to move toward the glue rod 13 until the driven gear 25 and the clamping gear 27 are engaged with the tooth groove 14. At this time, the pulling force applied to the unlocking ring 35 is cancelled, and the elastic force of the locking spring 32 drives the locking rod 31 to move downward, and drives the connecting piece 33 to move downward by adjusting the nut 34 until the bottom surface of the connecting piece 33 is against the top surface of the handle 11, and the locking rod 31 is reinserted into the transmission sleeve 28.

[0061] Due to the self-locking property of the worm gear assembly 23, the driven gear 25 cannot drive the output shaft of the first motor 21 to rotate through the reduction gear assembly 24, so the glue rod 13 cannot move along the axis independently. Therefore, the rubber hose will not slide due to the weight, and the rubber hose can be fixed.

[0062] When the rubber hose needs to be replaced, the unlocking ring 35 is pulled upward to separate the locking rod 31 from the transmission sleeve 28. Then a pulling force is applied to the tail of the glue rod 13 in the direction away from the rubber hose, and the glue rod 13 slides in the direction away from the rubber hose along the axis of the guide ring 12. The tooth groove 14 squeezes the driven gear 25 and the clamping gear 27 to both sides, driving the driven gear 25 and the clamping gear 27 away from the glue rod 13.

[0063] Until the glue rod 13 is completely separated from the rubber hose, the rubber hose is released.

[0064] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
