Description

Technical Field

[0001] The invention relates to the technical field of glue coating equipment, in particular to a nozzle assembly. Background Art

[0002] Thermoplastic warm edge coating machine is a professional equipment used to coat thermoplastic materials on the edge of glass. Warm edge spacer is a component used on the edge of hollow glass to separate two pieces of glass, and at the same time plays a role in sealing and reducing heat conduction. Thermoplastic warm edge coating machine consists of a body component, a conveying section component, a fan component, a glue coating head assembly component, a nozzle component, a glue supply connection component, and a glue extrusion barrel pump component. When coating the glass, the conveying section component transfers the glass to the front of the nozzle assembly, stops when it senses the positioning component, and the glue extrusion barrel pump assembly melts and squeezes the solid glue. The fluid glue flows to the glue coating head assembly through the glue supply hose connection component, and then the glue is accurately delivered to the nozzle assembly through the glue push cylinder assembly in the glue coating head assembly. The nozzle assembly is opened and closed by the servo motor to apply the glue to the surrounding of the glass.

[0003] After the existing nozzle assembly has completed coating a piece of glass, it is necessary to scrape the outer side of the nozzle assembly to remove the residual glue on the outer side. The traditional cleaning method is to extend a scraper blade to fit with the outer side of the nozzle assembly, then move the nozzle assembly upward, use the scraper blade to scrape off the residual glue on the outer side, and then retract the scraper blade and use a scraping plate that fits with the scraper blade to scrape off the residual glue on the scraper blade. In this method, although the retraction of the scraper blade can effectively scrape off the glue at the bottom of the scraper blade, some glue will remain at the front end of the scraper blade, and each time the scraper blade is docked with the nozzle assembly, the glue at the front end will cause the glue to fit with the outer side of the nozzle, and there is a situation where residual glue will remain at the front end of the nozzle, and the outer side of the nozzle assembly will contact the glass, and the residual glue will separate from the nozzle and mix with the new glue to fit on the outside of the glass, which will affect the bonding strength and sealing performance of the glue and glass, and affect the coating quality.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figure 1 - Figure 6 , a nozzle assembly shown in the figure includes a nozzle fixing assembly 1 and a base 2 fixed on the nozzle fixing assembly 1, a nozzle part 3 is fixed on the base 2, and also includes an adjusting component 4 installed on the base 2, and the size of the nozzle opening on the nozzle part 3 is adjusted by the adjusting component 4; and two scraping plates 5, the two scraping plates 5 are arranged on the outside of the nozzle part 3, and the two scraping plates 5 are installed with a driving part 6, and the two scraping plates 5 are driven to move by the driving part 6, and a front end scraper plate 7 and a side scraper plate 8 are arranged between the two scraping plates 5, and an electric push rod 9 is fixed to the outer end of the side scraper plate 8, and the electric push rod 9 drives it to move telescopically; and a scraper cleaning mechanism 10 arranged on the outer side of the scraper plate 5, and the scraper cleaning mechanism 10 drives the front end scraper plate 7 to move telescopically and removes the residual rubber material at its outer end;

[0035] In this solution, the nozzle fixing assembly 1 is an existing mechanism, which is used to drive the nozzle part 3 to move accordingly, so as to meet the requirements of the nozzle part 3 for spraying glue on the outer side of glass of various shapes, wherein the nozzle part 3 is provided with a corresponding glue injection tube, and the cavity design in the nozzle part 3 is used for the entry of glue, and the adjustment component 4 is used to control the nozzle size of the nozzle part 3, thereby controlling the width of the glass glue coating;

[0036] It should be noted that: after each gluing is completed, the nozzle part 3 is moved to the bottom of the scraping plate 5 through the nozzle fixing assembly 1, and then the front scraping plate 7 and the side scraping plate 8 are extended, and the nozzle part 3 is moved up, and the front scraping plate 7 and the side scraping plate 8 are used to scrape the outer side of the nozzle part 3 to scrape off the residual glue on the outer side, and then the two scraping plates 5 are moved closer to each other under the action of the driving part 6, and the outer sides of the front scraping plate 7 and the side scraping plate 8 are fitted, and the front scraping plate 7 and the side scraping plate 8 move backward, so that the residue scraped off the bottom of the front scraping plate 7 and the side scraping plate 8 is blocked and scraped off by the scraping plate 5;

[0037] It should also be noted that when the front end scraper 7 is driven back by the cleaning component 15, the residual glue on the outer end of the front end scraper 7 will be cleaned to prevent the residual glue on the outer end from adhering to the outer side of the nozzle part 3 when the front end scraper 7 is in contact with the outer side of the nozzle part 3.

[0038] For further information, see Figure 7 - Fig.10 as well as Fig.12 - Fig.14 The scraper cleaning mechanism 10 includes two brackets 11 arranged on the outside of the scraping plate 5, a screw rod 12 is rotatably installed between the two brackets 11, a slide bar 13 is fixed between the two brackets 11, a mobile motor 14 for driving the screw rod 12 to rotate is fixed to the outside of the bracket 11 away from the scraping plate 5 through a motor frame, and a cleaning component 15 for cleaning the residual glue at the outer end of the scraper is installed on the outside thereof, a connecting column 16 is fixed on the front end scraper plate 7, a moving cylinder 17 threadedly connected to the screw rod 12 is rotatably sleeved at the bottom of the connecting column 16, and the moving cylinder 17 is slidably sleeved with the slide bar 13, and a steering member 18 for driving the front end scraper plate 7 to turn is installed on the top of the connecting column 16;

[0039] Among them, the steering member 18 includes a steering gear 19 fixed on the top of the connecting column 16, a folding plate is fixed on the outside of the bracket 11 away from the scraping plate 5, a tooth plate 20 matched with the steering gear 19 is fixed on the outside of the folding plate, a fitting plate 21 is fixed on the outside of the connecting column 16, a fitting opening 22 is opened on the fitting plate 21, a fitting column 23 matched with the fitting opening 22 is fixed on the outside of the moving cylinder 17 through a connecting frame, and magnetic blocks that are magnetically attracted to each other are installed at the joint between the fitting opening 22 and the fitting column 23.

[0040] In this solution, the step of driving the front end scraper plate 7 to move;

[0041] First, when it is necessary to scrape glue on the outside of the nozzle part 3, the moving motor 14 is used to drive the screw rod 12 to rotate, so that the front scraper plate 7 moves forward and extends out of the scraping plate 5, and then fits the nozzle part 3, and cooperates with the upward movement of the nozzle part 3 to scrape off the residual glue on the outside;

[0042] Afterwards, the scraping plate 5 moves downward to fit with the front scraper plate 7, and cooperates with the moving motor 14 to drive the screw rod 12 to reverse, so that the front scraper plate 7 moves backward, and the rubber material scraped off the bottom of the front scraper plate 7 is scraped away;

[0043] Afterwards, the front scraper plate 7 continues to retreat, so that the steering gear 19 is meshed with the tooth plate 20, and when retreating, the steering gear 19 and the connecting column 16 are driven to turn synchronously, so that the front scraper plate 7 turns 180 degrees and docks with the cleaning component 15 to clean the residual glue on the outer end of the front scraper plate 7;

[0044] Finally, the front end scraper plate 7 that has cleaned the outer end is moved forward again by rotating the mobile motor 14, and after being reset 180° by the tooth plate 20, it extends through between the two scraping plates 5 to scrape the nozzle part 3 again.

[0045] It should be noted that, in the process of the front end scraper plate 7 moving forward and backward, in order to ensure that its outer end can stably fit with the outer side of the nozzle part 3 and the cleaning component 15, the designed fitting column 23 is docked with the fitting port 22 in the fitting plate 21, and the magnetic block is used to make the two fit together. After that, without being affected by external force, the front end scraper plate 7 and the screw rod 12 can be kept in a parallel state for movement. At the same time, the number of teeth on the tooth plate 20 is half of the number of teeth on the steering gear 19. When the front end scraper plate 7 moves through the tooth plate 20, it can accurately turn 180°.

[0046] For further information, see Figure 7-Figure 9 The cleaning assembly 15 includes a connecting plate 24 fixed to the bracket 11, two connecting rods 25 are slidably plugged on the connecting plate 24, cleaning plates 26 are fixed on the outside of the two connecting rods 25, a driving motor 27 is fixed on the connecting plate 24, a half gear 28 is fixed to the output end of the driving motor 27 through a coupling, a tooth row 29 meshing with the half gear 28 is fixed to the bottom of the cleaning plate 26, an extrusion spring 30 for pushing the cleaning plate 26 outward is sleeved on the outside of the connecting rod 25, and a brush for removing the residual rubber on the outer end of the front end scraper plate 7 is fixed on the outside of the cleaning plate 26.

[0047] The principle of using the cleaning component 15 to clean the outer end of the front scraper plate 7 is as follows: when the front scraper plate 7 moves to fit with the outer brush of the cleaning plate 26, at this time, the motor 27 is driven to drive the half gear 28 to rotate, and under the meshing action with the tooth row 29, the cleaning plate 26 moves accordingly. When the half gear 28 is not meshed with the tooth row 29, the moved cleaning plate 26 is reset by squeezing the spring 30, and the reciprocating operation is performed, thereby driving the cleaning plate 26 to reciprocate on the connecting plate 24 with the help of the connecting rod 25, effectively cleaning and removing the residual glue on the outer end of the front scraper plate 7, and avoiding the residual glue being left on the outer side of the nozzle part 3 when it contacts with the nozzle part 3 later, thereby affecting its subsequent coating.

[0048] Further, the driving part 6 includes two mounting frames 31, two bidirectional threaded rods 32 are rotatably mounted in the two mounting frames 31, and the two ends of the two bidirectional threaded rods 32 are respectively threadedly connected with the two scraping plates 5, a driving motor 33 is fixed in one of the mounting frames 31 through a motor frame, a driving gear 34 is fixed at the output end of the driving motor 33, a transmission gear 35 meshing with the driving gear 34 is fixed on the outer side of one of the bidirectional threaded rods 32, and a linkage member 36 is fixed on the top of the two bidirectional threaded rods 32;

[0049] Among them, see Figure 7 - Fig.10 The linkage member 36 includes a linkage gear 37 fixed to the top of the bidirectional threaded rod 32, and a synchronous belt 38 is meshed on the outer sides of the two linkage gears 37;

[0050] The driving part 6 drives the two scraping plates 5 to move:

[0051] By driving the motor 33, the driving gear 34 rotates, and drives the transmission gear 35 and one of the two-way threaded rods 32 to rotate. Under the action of the two linkage gears 37 and the synchronous belt 38, the two two-way threaded rods 32 rotate synchronously, so that the two scraping plates 5 move in the same direction along the two-way threaded rods 32 to perform opening and closing operations. When the two scraping plates 5 are opened, the front scraper plate 7 and the side scraper plate 8 extend to scrape off the residual rubber material on the outside of the nozzle part 3. When the two scraping plates 5 are closed, they fit with the top and bottom of the front scraper plate 7 and the side scraper plate 8, and then cooperate with the retreat of the front scraper plate 7 and the side scraper plate 8 to scrape off the rubber material scraped off the bottom of the front scraper plate 7 and the side scraper plate 8.

[0052] In this solution, the process of removing the residual rubber outside the nozzle part 3 and preventing the rubber from being left on the nozzle part 3 for scraping includes the following steps:

[0053] In the first step, the nozzle part 3 moves to the scraping plate 5 after finishing the coating on the glass;

[0054] In the second step, the driving part 6 drives the two scraping plates 5 to open, the electric push rod 9 drives the side scraper 8 to extend, and the cleaning mechanism 10 drives the front scraper 7 to extend;

[0055] In the third step, the side scraper 8 and the front scraper 7 are attached to the outer side of the nozzle part 3, the nozzle part 3 is moved upward, and the side scraper 8 and the front scraper 7 are used to scrape off the residual rubber material;

[0056] In the fourth step, the driving part 6 drives the two scraping plates 5 to close, and fit with the outer sides of the side scraping plates 8 and the front scraping plates 7, and then the side scraping plates 8 are retracted by the electric push rod 9, and the cleaning mechanism 10 drives the front scraping plates 7 to retract, and the residual rubber at the bottom of the side scraping plates 8 and the front scraping plates 7 is scraped off;

[0057] In the fifth step, when the front scraper 7 is retreating, the steering member 18 drives the front scraper 7 to turn 180 degrees and docks with the cleaning component 15 to clean the residual rubber material on the outer end of the front scraper 7;

[0058] Step 6: Repeat steps 1 to 6 to automate the glass coating and nozzle scraping operations.

[0059] In this solution, when the front end of the nozzle part 3 is coating, the outer side of the front end will be in contact with the glass, and will move along the glass surface during the movement. Therefore, if the outer side of the front end of the nozzle part 3 is left with residual glue at the outer end of the front scraper 7, the old material will fall onto the glass and mix with the newly coated glue. The glue used by the thermoplastic warm edge coating machine usually has strict composition and performance requirements, and the quality of the glue will decrease after impurities are mixed in. For example, in the production of warm edge spacers of insulating glass, the purity of the glue is directly related to the bonding strength and sealing performance between the spacers and the glass. If residual glue is mixed into the glue, it may cause the bonding between the warm edge spacers and the glass to be loose, resulting in air leakage, moisture permeability and other problems, affecting the thermal insulation, sound insulation and other properties of the insulating glass.

[0060] Example 2: Please refer to Fig. 9 - Fig.11 The present embodiment further illustrates the first embodiment, and the difference lies in that a glue removal plate 39 is added to the outside of the scraping plate 5 to effectively transfer the residual glue on the outside of the scraping plate 5 to avoid secondary docking with the front end scraping plate 7.

[0061] Specifically, a glue removal plate 39 is fixed on the outer side of the scraping plate 5, and the glue removal plate 39 is in contact with the outer wall of the scraping plate 5 near the front end of the scraping plate 7. An inclined plate is fixed on the top of the glue removal plate 39, and a knocking part 40 for discharging residual glue on the outer side of the inclined plate is fixed on the inner wall of the glue removal plate 39.

[0062] Among them, the knocking part 40 includes a docking plate 41 fixed on the degumming plate 39, a rotating rod 42 is rotatably installed on the docking plate 41, a rotating gear 43 is fixed to the bottom of the rotating rod 42, a driving gear 44 is fixed to the bottom of one of the two-way threaded rods 32, and a synchronous belt 45 is meshed on the outer sides of the rotating gear 43 and the driving gear 44, an elastic rod 46 is fixed to the top of the rotating rod 42, a knocking ball is fixed to the outer end of the elastic rod 46, and a blocking rod 47 is fixed to the docking plate 41.

[0063] In this solution, after the scraping plate 5 scrapes away the rubber material at the bottom of the front scraper plate 7, the scraped rubber material will gather, but the rubber material will not be transferred, and there is a situation where the old rubber contacts the front scraper plate 7 again;

[0064] Through the designed glue removal plate 39 and the inclined plate on the top, the scraped residual glue will be transferred to the inclined plate every time the scraping plate 5 is raised or lowered, and each time the bidirectional threaded rod 32 is rotated, the driving gear 44 will drive the rotating gear 43 to rotate, so that the rotating rod 42 will rotate on itself, and the elastic rod 46 will rotate. When passing through the blocking rod 47, it will be blocked and bent until the bending arc reaches the blocking rod 47. The bent elastic rod 46 will restore its state due to elasticity, thereby hitting the inner wall of the inclined plate to achieve a knocking action, effectively shaking the residual glue on the inclined plate downward to avoid residual glue accumulation.

[0065] Example 3: Please refer to Figure 2 , Figure 5 and Figure 6 This embodiment further describes other embodiments, and the difference lies in that a specific implementation of the adjustment component 4 is disclosed.

[0066] Specifically, the adjustment component 4 includes a rack slider 48 slidably docked with the top of the nozzle portion 3 and a servo motor 49 fixed to the outside of the base 2 through a motor frame, and the output end of the servo motor 49 is fixed with a gear shaft 50 meshing with the rack slider 48 through a coupling;

[0067] In this solution, the servo motor 49 rotates, thereby driving the gear shaft 50 to rotate, so that the rack slider 48 meshing therewith moves accordingly. By controlling the moving position between the rack slider 48 and the top of the nozzle part 3, the size of the nozzle opening of the nozzle part 3 can be controlled to meet the coating operation of glue coating of different widths. At the same time, when scraping the residual glue on the outside of the nozzle part 3, the rack slider 48 moves to the outermost end to facilitate the scraping off of the residual glue on the outside.
