Description

Technical Field

[0001] The invention relates to the technical field of glue spraying equipment, and in particular to a glue spraying machine which is convenient for adjusting the glue spraying angle. Background Art

[0002] In the fields of building decoration, equipment bonding, packaging, caulking, and leak repair, glass glue is used for sealing or gluing. Glass glue is generally used in home decoration in the following places: the dumb joints on the back of wooden lines, sanitary ware, toilets, makeup mirrors in the bathroom, the gaps between sinks and walls, etc. These places require glass glues with different properties.

[0003] At present, the glue application operation of glass glue and other adhesives is mostly carried out by glue guns. When using, the glue gun is manually held, the glue nozzle is aimed at the position to be applied, and the glue in the glue cylinder is squeezed out of the glue nozzle to form a glue filling belt at the application position, thereby realizing the glue application operation.

[0004] There are two ways to apply glue: push glue and pull glue. Generally speaking, push glue can increase the glue area and reduce the glue amount; while pull glue is easier to do in one go, but it is easy to consume energy.

[0005] However, whether it is the push glue or the pull glue construction method, when dealing with the corners or the bending area of ​​the glue application area, due to the obstruction of the wall or other objects, the existing single push glue or pull glue method cannot achieve one-time continuous operation, making the glue application work of the entire glue application area intermittent, affecting the glue application quality and efficiency. When dealing with such areas, the traditional push-pull glue process requires multiple segmented glue application, and even manual repair at the end, which takes a long time and the quality of the treatment cannot be reliably guaranteed.

[0006] Therefore, when dealing with such areas, many workers either constantly fiddle with the angle of the glue gun nozzle, which makes the workers' holding posture unstable and inconvenient to operate; or they add a soft rubber tube to the glue nozzle, and use the bending characteristics of the soft rubber tube to adjust the glue discharge angle of the glue nozzle. However, since the soft rubber tube is continuously subjected to the impact of the rubber extrusion during glue discharge, the soft rubber tube is always in a state of tending to be straightened, so when using it, it is necessary to manually hold the glue gun in one hand and the soft rubber tube in the other hand. In this way, the workers' arms are more likely to get sore and tired, and they need to rest many times, which affects the efficiency of gluing. Alternatively, the existing glue nozzle is improved by dividing the glue nozzle into two rotatably connected hoses so that the glue discharge angle can be adjusted; and a screw is set at the rotating connection of the two hoses, and the screw is screwed and pressed against the rotating connection, so that the two hoses are braked, thereby playing the role of keeping the fixed position after adjusting the angle. However, this method can only adjust a single angle at a time. If you need to adjust the angle again, you need to loosen the screw, hold the glue gun and match the glue nozzle with the glue application position, adjust the relative angle of the two hoses, and then tighten the screw to fix the two hoses relatively. It is troublesome to use.

[0007] To this end, the present invention provides a glue spraying machine that is convenient for adjusting the glue spraying angle, so that the glue nozzle of the glue gun can adjust the angle more conveniently and the angle can be adjusted without stopping the machine. Summary of the invention

[0042] The clamping mechanism comprises a cylindrical placement tube 1, which is used to embed a rubber tube 4. Both ends of the placement tube 1 are open, and the outer walls of the openings at both ends of the placement tube 1 are provided with external threads, and the sealing cap 3 and the end cap 2 are respectively screwed on the external threads at both ends. The end of the placement tube 1 located at the sealing cap 3 is the end for taking and placing the rubber tube 4, and the end of the placement tube 1 located at the end cap 2 is the end for discharging the rubber tube 4. A handle 15 is provided on the side wall of the lower end of the sealing cap 3.

[0043] (2) A glue pressing mechanism, used for squeezing the rubber material in the rubber cylinder 4 to discharge the rubber.

[0044] The glue pressing mechanism includes an air cylinder 7 detachably mounted on the cover 3. The air cylinder 7 is open at one end facing the placement cylinder 1, and is used to dock with the rubber cylinder 4 placed in the placement cylinder 1; the air cylinder 7 is meshed at one end away from the placement cylinder 1, which is used for ventilation and heat dissipation. A partition 8 is provided inside the open end of the air cylinder 7, and the air cylinder 7 is sealed and isolated from the placement cylinder 1 by the partition 8. Two chambers are provided in the air cylinder 7, and an air intake pump 9 and an air suction pump 10 are respectively installed in the two chambers by screw fastening, and the air intake pump 9 and the air suction pump 10 are arranged at intervals. The air filling port of the air intake pump 9 and the air suction port of the air suction pump 10 both penetrate the partition 8 and face the inside of the placement cylinder 1. A piston 24 is provided in the cover 3, which is used to squeeze the rubber in the rubber cylinder 4. A pneumatic glue dispensing machine device is formed. The air intake pump 9 and the air suction pump 10 are both micro air pumps, which reduce the external space volume, reduce the size of the equipment, and make the equipment more flexible to use.

[0045] See attached Fig.12As shown, a double-control switch is provided on the handle 15, and the double-control switch has three terminals, among which the terminals marked L or COM are the incoming wires. L1 and L2 are connected to the air intake pump 9 and the air extraction pump 10 respectively, so that the air intake pump 9 and the air extraction pump 10 are connected in parallel to a circuit. Among them, L1 and L2 are the two points that the switch contacts when it is turned upward and downward. That is, the switch button is pushed downward to connect L1, at which time the air intake pump 9 is started and inflates the placement cylinder 1, and the piston 24 is pushed by the compressed air to squeeze the rubber material in the rubber cylinder 4 toward the rubber outlet of the rubber cylinder 4; the switch button is pushed upward to connect L2, at which time the air extraction pump 10 is pneumatic and the gas in the placement cylinder 1 is pumped out, so that the piston 24 is reset; the switch button is suspended, that is, it is located between the contact points of L1 and L2 without contacting the two contact points, and is in a power-off state at this time, and neither air is extracted nor inflated. It is also possible to directly set two button switches on the handle 15, and the two button switches correspond to the air intake pump 9 and the air exhaust pump 10 respectively, so that the two air pumps have independent control circuits.

[0046] (3) A glue discharging mechanism, used to guide the glue material in the rubber cylinder 4 to be discharged.

[0047] The glue discharging mechanism includes a glue discharging tube 5 and a glue nozzle 6. The glue discharging tube 5 is placed on the end cover 2 and the glue inlet of the glue discharging tube 5 passes through the end cover 2. After the glue cylinder 4 is placed in the placement cylinder 1, the glue discharging tube 4 is embedded in the glue inlet of the glue discharging tube 5. The glue discharging tube 5 and the glue inlet of the glue nozzle 6 are both open spherical, and the spherical glue inlet of the glue nozzle 6 is buckled on the spherical glue discharging tube 5, so that the glue discharging tube 5 and the internal pipeline of the glue nozzle 6 are connected. In addition, two rotating shafts are symmetrically arranged on both sides of the outer wall of the spherical glue discharging tube 5, and the side wall of the spherical glue inlet of the glue nozzle 6 is provided with a mounting hole corresponding to the rotating shaft. Through the cooperation of the rotating shaft and the mounting hole, the glue nozzle 6 is rotatably installed on the glue discharging tube 5.

[0048] (4) Angle adjustment mechanism, used to adjust the deflection angle of the glue nozzle 6 in the glue dispensing mechanism.

[0049] The angle adjustment mechanism includes a cylindrical handle 17, which is divided into an upper handle 1701 and a lower handle 1702. The lower side wall of the end cover 2 is provided with an extension plate 16 that fits the outer wall of the placement tube 1, and the lower end of the extension plate 16 is provided with an internal thread sleeve 23, and the upper end surface of the upper handle 1701 is provided with an external thread joint. Through the cooperation of the internal thread sleeve 23 and the external thread joint, the upper handle 1701 can be detachably installed on the extension plate 16, and then the handle 17 is set on the end cover 2.

[0050] An internal thread is provided on the inner wall of the port of the upper handle 1701 facing the lower handle 1702, and an external thread is provided on the inner wall of the port of the lower handle 1702 facing the upper handle 1701. Through the cooperation between the internal thread and the external thread, the upper handle 1701 and the lower handle 1702 can be detachably connected to facilitate the disassembly and assembly of the internal components.

[0051] The inner wall of the upper handle 1701 is provided with a plurality of bosses in a circular array, and a mounting seat 1704 is abutted below the plurality of bosses. After the lower handle 1702 is screwed onto the upper handle 1701, the upper end surface of the lower handle 1702 abuts against the lower end surface of the mounting seat 1704, and the mounting seat 1704 is positioned in the upper handle 1701 through the upper end surface of the lower handle 1702 and the buckling with the bosses, so that the mounting seat 1704 will not float up and down. The outer edge surface of the mounting seat 1704 is provided with a platform corresponding to the bosses, and pin holes are provided at the corresponding positions of the bosses and the platform. The pin shaft is inserted into the pin hole to limit the mounting seat 1704 and prevent the mounting seat 1704 from deflecting.

[0052] The axis of the mounting seat 1704 is provided with a threaded hole, and a support shaft 1705 is screwed on the inner thread of the threaded hole, and the support shaft 1705 is located below the mounting seat 1704. A universal bearing 17010 is provided at the lower end of the support shaft 1705, and a crank 17011 is provided on the outer ring of the universal bearing 17010, and a pull rope 18 is connected to the side wall of the crank 17011. The other end of the pull rope 18 rises along the inner wall of the handle 17, and a through hole 1 for the pull rope 18 to pass through is provided on the mounting seat 1704, and a through hole 2 for the pull rope 18 to pass through is provided on the upper end of the side wall of the upper handle 1701. After the pull rope 18 passes through the through hole 1 and the through hole 2, it is connected to the outer wall of the spherical glue inlet of the glue nozzle 6.

[0053] A second pull rope 19 is also connected to the outer wall of the spherical glue inlet of the glue nozzle 6. The second pull rope 19 is symmetrically arranged with the first pull rope 18. The plane where the second pull rope 19 and the first pull rope 18 are located is perpendicular to the rotating axis of the glue nozzle 6. A hook-shaped hanging ear 21 is provided on the end cover 2. The hanging ear 21 is provided with a through hole 3, and the movable terminal of the second pull rope 19 passes through the through hole 3. The movable end of the second pull rope 19 is connected to a baffle, and a spring 20 is provided between the baffle and the hanging ear 21.

[0054] (5) A limiting mechanism allows the crank handle 17011 to remain stationary after being swung.

[0055] The limiting mechanism includes a threaded shaft section 1706 arranged on the support shaft 1705, and the threaded shaft section 1706 is located above the universal bearing 17010. A cylinder seat 1707 is screwed on the threaded shaft section 1706, and a hemispherical damping seat 1708 is provided at the lower end of the cylinder seat 1707. A hemispherical damping plate 1709 is installed on the outer ring of the universal bearing 17010, and an outer edge ring 22 is provided at the end of the damping plate 1709, and the outer edge ring 22 is fastened to the crank 17011 through screws. The hemispherical damping seat 1708 is located above the hemispherical damping plate 1709, and the mating surfaces of the damping seat 1708 and the damping plate 1709 are both damping surfaces (frosted surfaces).

[0056] Here, there are two driving structures for the rotation of the cartridge seat 1707: The first is to set a push handle 17012 on the side wall of the cylinder seat 1707, and a notch 17013 is provided on the side wall of the handle 17. The handle end of the push handle 17012 extends out of the handle 17 from the notch 17013, and the notch 17013 is spiral. When in use, the end of the push handle 17012 is pushed, and the push handle 17012 spirally descends along the notch 17013, and then drives the cylinder seat 1707 to rotate and descend, and the cylinder seat 1707 drives the damping seat 1708 to descend, so that the outer wall of the damping seat 1708 is buckled on the inner wall of the damping plate 1709, and the damping plate 1709 is braked through friction damping, and then the crank 17011 installed integrally with the damping plate 1709 is braked. This cylinder seat 1707 and the push handle 17012 can be integrally formed and arranged, reducing the workpiece production process and reducing production costs.

[0057] The second type is that a collar 17014 is sleeved on the outer wall of the cartridge seat 1707, and the collar 17014 and the cartridge seat 1707 are vertically slidably matched. In this case, the push handle 17012 is set on the collar 17014, and the notch 17013 is set horizontally. When in use, the end of the push handle 17012 is pushed, and the push handle 17012 is horizontally deflected to drive the collar 17014 to rotate horizontally, and the collar 17014 drives the cartridge seat 1707 to rotate, and the cartridge seat 1707 spirally descends along the threaded shaft section 1706, so that the damping seat 1708 descends and buckles on the damping plate 1709, realizing the braking of the crank handle 17011. This cartridge seat 1707 is separately set from the push handle 17012, and after the push handle 17012 is used multiple times and bent, it can be replaced alone without being discarded as a whole.

[0058] According to the above technical solution, when used: When performing barrier-free gluing (glue can be pushed or pulled directly without interference), hold the handle 15 with one hand and support the handle 17 with the other hand. Aim the glue nozzle 6 at the gluing area, start the air pump 9, and the air pump 9 injects compressed gas between the piston 24 and the cover 3. The piston 24 is driven by the compressed gas and squeezed into the rubber cylinder 4 (the rubber cylinder 4 is filled with rubber, and the rubber inlet of the rubber cylinder 4 is generally openable, with a material partition plate inside. Pushing the material partition plate can pressurize the rubber and squeeze it out from the rubber outlet of the rubber cylinder 4.), the piston 24 squeezes the rubber and causes the rubber to flow into the rubber outlet of the rubber cylinder 4. The rubber is squeezed into the rubber outlet pipe 5 from the rubber outlet of the rubber cylinder 4, and enters the glue nozzle 6 along the rubber outlet pipe 5, and finally smeared on the glue coating area from the glue nozzle 6 to realize the gluing process. After the glue application is completed, the air inlet pump 9 is first turned off, and then the air pump 10 is turned on to draw out the compressed air in the placement cylinder 1 to form a negative pressure. Under the action of the negative pressure, the piston 24 is reset. In the above, the damping seat 1708 is buckled on the damping plate 1709 to brake the crank 17011 to prevent the crank 17011 from being accidentally touched and causing the glue nozzle 6 to deviate from spraying. At the same time, when applying glue, the glue nozzle 6 will not be easily deflected under the impact of the glue material and the pulling action of the spring 20, the second pull rope 19, and the first pull rope 18.

[0059] When gluing at a corner (the gluing position and the glue gun collide or interfere), the thumb of the hand holding the handle 17 pushes the push handle 17012 to rotate counterclockwise, thereby driving the cylinder seat 1707 to rise along the threaded shaft section 1706, so that the damping seat 1708 and the damping plate 1709 are separated, and the crank 17011 is no longer braked. Then the lower side of the palm presses against the crank 17011 to deflect, and the crank 17011 deflects and pulls the pull rope 18. The pull rope 18 pulls the glue nozzle 6 to deflect, thereby adjusting the gluing angle of the glue nozzle 6. After the nozzle 6 is adjusted to a suitable angle, the thumb of the hand pushes the push handle 17012 to rotate clockwise, thereby driving the cylinder seat 1707 to descend along the threaded shaft section 1706, so that the damping seat 1708 is buckled on the damping plate 1709, braking the crank handle 17011, and the pull rope 18 is also limited. Therefore, with the cooperation of the spring 20, the pull rope 2 19 and the pull rope 18, the nozzle 6 will not be easily deflected after adjustment.

[0060] In summary, in this solution, the crank handle 17011 can be shaken to drive the glue nozzle 6 to deflect through the pull rope 18, and then the crank handle 17011 is braked through the cooperation of the damping seat 1708 and the damping plate 1709, and then the glue nozzle 6 is limited. It can be operated with one hand, making the adjustment process of the glue nozzle 6 more convenient; and when adjusting, there is no need to stop the work, and it can be adjusted according to the needs at the glue coating station, which is more flexible to use. And the compressed gas is injected and extracted through the air pump, and there is no need to set up an external compressor, making the equipment more flexible.

[0061] In this solution, there is a gap or transition fit between the placement tube 1 and the rubber tube 4, and sealing gaskets are provided between the sealing cap 3 and the end cover 2 at both ends of the rubber tube 4, between the sealing cap 3 and the placement tube 1, and between the end cover 2 and the placement tube 1, so as to ensure the sealing of the rubber tube 4 after it is placed in the placement tube 1, and avoid air leakage that affects the process of starting the glue injection.

[0062] In this solution, a plurality of guide rings 25 are provided on the end cap 2, and the plurality of guide rings 25 are located on the same vertical plane.

Bolts are passed through the countersunk holes and the through holes, thereby realizing a detachable connection between the gas cylinder 7 and the cover 3, and the bolts are hidden in the countersunk holes, which does not affect the placement of the piston 24 in the sink groove 12. The bolt installation parts are all provided with sealing rings to prevent air leakage. Alternatively, internal threads and external threads can be provided between the gas cylinder 7 and the cover 3, respectively, and a detachable connection can also be achieved through thread matching.

[0067] In this solution, silencers are provided at both the air inlet of the air intake pump 9 and the air outlet of the air exhaust pump 10 to reduce noise.

[0068] In this solution, the thread tightness between the support shaft 1705 and the mounting seat 1704 is greater than the thread tightness between the cartridge seat 1707 and the threaded shaft section 1706, so as to prevent the support shaft 1705 from being synchronously driven when the cartridge seat 1707 is driven to rotate. Alternatively, an additional screw is connected between the upper end of the support shaft 1705 and the mounting seat 1704, and the support shaft 1705 is fastened to the mounting seat 1704 by the screw, which can also prevent the support shaft 1705 from being driven.

[0069] In the present solution, an extension nozzle is further provided, which is screwed onto the glue outlet of the glue nozzle 6 by means of a buckle or a thread, so as to extend the extension of the glue nozzle 6 .

[0070] In this solution, the single arrangement of each device in the handle 17 facilitates the disassembly and assembly of the internal components.

[0071] In this solution, a hook is provided on the piston 24 facing the gas cylinder 7. When the piston 24 is embedded in the rubber cylinder 4, the sealing cap 3 is unscrewed to take out the rubber cylinder 4, and then the piston 24 is taken out by hooking the hook behind the piston 24.
