Referring to fig. 1 to 5, the following description provides several embodiments of the apparatus and process for manufacturing a glue injection corner brace according to the present invention.

As shown in fig. 2 to 4, an apparatus for manufacturing a glue injection corner fitting according to a first embodiment of the present invention includes a can 100, a spray gun assembly 200, and a height adjusting device 300.

The can 100 is provided with two, one can 100 for containing the component A of the two-component resin and the other can 100 for containing the sum component B of the two-component resin. Each can 100 is provided with a tapping pipe 110. It is understood that the two-component resin can be two-component PU glue (namely two-component polyurethane glue) or two-component EP glue (namely two-component epoxy resin glue), and both the two-component PU glue and the two-component EP glue comprise a component A and a component B, wherein the component A is a main agent, and the component B is a curing agent.

Each can 100 has a hollow cavity formed therein, and is capable of storing a certain amount of component a or component B, and a material outlet is formed in the bottom of the can 100, and one end of the discharge pipe 110 is connected to the material outlet. Thus, component a and component B can be conveyed out via the respective discharge pipe 110. The tapping pipe 110 is a flexible pipe that can be bent. It will be appreciated that either component a or component B may be pneumatically or pumpably output from the canister 100. For example, the tapping pipe 110 is provided with a transfer pump.

Of course, both tanks 100 may also be provided with material inlets to supplement the storage of component a and component B. In addition, the inside of both tanks 100 is protected with an inert gas such as nitrogen.

The spray gun assembly 200 includes a dispensing head 210, a spray head 230, and a static mixer 220.

Wherein, the inside of the distributing head 210 is hollow and formed with a cavity, the distributing head 210 is provided with a discharge port and two feed ports, the discharge port and the two feed ports are both communicated with the cavity, one feed port is correspondingly connected with one discharge pipe 110, and the other feed port is correspondingly connected with the other discharge pipe 110. Thus, component a and component B flow through the respective discharge pipes 110 into the cavity of the dispensing head 210.

In this embodiment, two feed inlets are located at opposite ends of the dispensing head 210, the feed inlets are located below the discharge outlets, the opening direction of the feed inlets is upward, the opening direction of the discharge outlets is downward, and the discharge outlets are located between the two feed inlets.

It will be appreciated that the flow rates of component a and component B into the cavity may be controlled so that the components a and B are mixed in a certain ratio.

In this embodiment, the apparatus for manufacturing the glue injection corner connector further includes a control device and a flowmeter. Each discharge pipe 110 is provided with a flow meter, which is electrically connected with the control device, and transmits flow data to the control device.

The static mixers 220 are provided in plurality, and a length direction of each static mixer 220 extends in an up-down direction, and each static mixer 220 has an upper end inlet and a lower end outlet. The plurality of static mixers 220 are sequentially arranged in the up-down direction and sequentially connected in series, thereby forming a mixing unit. The upper inlet and the lower outlet of the mixing unit are connected to the discharge port and the spray head 230, respectively. The spouting port of the spouting head 230 is disposed downward.

It will be appreciated that static mixer 220 is conventional in the art, and those skilled in the art will appreciate the specific structure and operation thereof and will not be further described herein. The number of static mixers 220 may be set according to practical situations, and is not particularly limited herein. Any adjacent two static mixers 220 may be detachably connected by a threaded structure.

The static mixer 220 and the spray head 230 are cylindrical, and the design of the outer diameter sizes of the static mixer 220 and the spray head 230 only needs to meet the requirement of being capable of extending into the glue injection cavity of the corner joint profile.

In any adjacent two static mixers 220, the upper inlet is connected to the lower outlet. And the upper inlet of the static mixer 220 positioned at the uppermost side is connected with the discharge port of the dispensing head 210 so that the components a and B positioned in the cavity can enter the mixing unit and flow in a spiral manner inside the mixing unit, so that the components a and B can be uniformly mixed and fully reacted to generate the two-component resin. The lower outlet of the static mixer 220 located at the lowermost side is connected to the spray head 230, and then the two-component resin can flow out of the spray head 230. The number of the spouts of the spouting head 230 may be one or two, and is not particularly limited herein.

In the present embodiment, the static mixer 220 may be made of a plastic material, which can reduce the weight and manufacturing cost of the static mixer 220. Moreover, the housing of the static mixer 220 may be made of a transparent plastic material so as to observe the flow of the two-component resin in the static mixer 220, and to facilitate checking whether the inside of the static mixer 220 is clogged due to the solidification of the two-component resin. The spray head 230 may be made of a metallic material such as iron.

In this embodiment, static mixer 220 is removably coupled to dispensing head 210 and spray head 230, respectively. Specifically, the static mixer 220 and the dispensing head 210 may be connected by a screw portion, and the static mixer 220 and the nozzle 230 may be connected by a screw portion. So set up, conveniently split spray gun assembly 200 to wash static mixer 220 and shower nozzle 230 or quick replacement, can reduce maintenance degree of difficulty and cost.

The height adjusting device 300 includes a servo driving mechanism and a lifting base 350.

Wherein, the dispensing head 210 may be fixedly connected to the lifting base 350 by bolts. The output end of the servo driving mechanism is connected with the lifting seat 350, and after the servo driving mechanism is started, the height position of the lifting seat 350 can be adjusted by the output end of the servo driving mechanism. The servo driving mechanism is electrically connected with the control device, and the control device can send a control instruction to the servo driving mechanism to control the start and stop of the servo driving mechanism. It will be appreciated that the servo drive mechanism is capable of precisely controlling the height position of the lift base 350 and thus the spray gun assembly 200.

The working process of the manufacturing equipment of the glue injection corner connector provided by the embodiment is as follows: firstly, a long angle code section bar is prepared, the angle code section bar can be manufactured by extrusion technology, etc., and generally, the length of the angle code section bar can reach 3 meters. And (3) placing the corner brace section bar on a working platform in a vertical state, wherein the glue injection cavity of the corner brace section bar penetrates through the upper end face and the lower end face of the corner brace section bar.

The spray gun assembly 200 is then moved up into position using the height adjustment device 300, with the spray gun assembly 200 positioned over the corner key profile and the spray head 230 and all static mixers 220 aligned with the glue injection cavity of the corner key profile. Then, the height adjusting device 300 is started to drive the spray gun assembly 200 to move downwards, so that the spray head 230 and all the static mixers 220 can extend into the glue injection cavity of the corner joint profile, and at the moment, the spray head 230 and the static mixers 220 are not contacted with the inner wall surface of the glue injection cavity.

When the nozzle 230 moves downward to a set position under the driving action of the height adjusting device 300, the height adjusting device 300 stops to make the height distance between the nozzle of the nozzle 230 and the lower end surface of the angle pattern reach a set value, which may be 1mm to 50mm. At this time, the bulky dispensing head 210 may be located above the corner brace profile without extending into the glue injection cavity.

Subsequently, the component a and the component B in the two tanks 100 are delivered into the cavity of the dispensing head 210 through the corresponding discharge pipes 110, the component a and the component B are combined and flow together into the mixing unit, after spiral flow and full mixing, the component a and the component B can fully react and at least partially form a two-component resin, and finally flow out from the spouting port of the nozzle 230. The flowing out double-component resin can enter the glue injection cavity and starts to fill the glue injection cavity from bottom to top.

The two-component resin can be solidified and bonded with the inner wall surface of the glue injection cavity, the two-component resin forms a resin component with a fixed shape in the glue injection cavity of the corner brace section bar, and the cross section shape of the resin component is consistent with that of the glue injection cavity.

Next, the height adjustment device 300 is activated, so that the height adjustment device 300 drives the spray gun assembly 200 to slowly move upwards. The dispensing head 210 may be configured with a ranging sensor, and the ranging sensor and the height adjustment device 300 are electrically connected to the control device, respectively. The control device may be a PLC controller, a 51 single chip microcomputer or an upper computer, which is not particularly limited herein.

Since the height distance between the dispensing head 210 and the ejection head 230 is known, the ranging sensor can detect the height position of the ejection head 230 in real time, and can determine whether the ejection head 230 reaches the set position. Moreover, when the casting of the two-component resin is started, the amount of the two-component resin in the injection cavity is continuously increased, so that the upper surface of the resin member is continuously raised, and then the height difference between the upper surface of the resin member and the nozzle of the nozzle 230 is obtained by the ranging sensor, and the resin member collides with the nozzle 230 as the height difference is continuously reduced.

Therefore, the ranging sensor can collect data in real time and transmit the data to the control device, the control device can control the operation of the height adjusting device 300 according to the comparison of the real-time data and the set data, so that the height adjusting device 300 drives the nozzle 230 to move upwards by a certain distance, and the height difference between the nozzle of the nozzle 230 and the upper surface of the resin member is in a safe set range, for example, the set range of the height difference can be set between 5mm and 50mm. When the height difference is greater than the set range, the height adjusting device 300 is controlled to stop.

In the continuous glue injection process, the control device performs logic judgment according to the data acquired by the ranging sensor and controls the operation of the height adjusting device 300, so that the height position of the nozzle 230 rises along with the rising of the upper surface of the resin member until the resin member completely fills the whole glue injection cavity of the corner code section bar. At this point, the nozzle 230 has moved up out of the injection cavity.

After the resin component is firmly adhered with the corner code section bar, the corner code section bar can be taken away, and the corner code section bar is cut by a cutting machine so as to manufacture a plurality of glue injection corner codes. Therefore, the manufacturing efficiency of the glue injection corner connector can be improved, and the daily output of the glue injection corner connector can be increased.

It can be appreciated that in the prior art, the component a and the component B are uniformly mixed after leaving the can 100 and fully react to generate the two-component resin, and the two-component resin reaches the glue injection cavity of the corner joint profile through the long conveying pipeline, so that the two-component resin is partially cured in the process, which can cause the conveying pipeline to be blocked, and the maintenance difficulty is high, so that the overall manufacturing efficiency is affected. In addition, the two-component resin is poured downwards from the upper part of the corner brace section bar and can be quickly solidified in the falling process, so that the connection effect of the two-component resin and the corner brace section bar is weakened after the two-component resin falls in place, the two-component resin cannot well fill the glue injection cavity of the corner brace section bar, a gap exists between a resin component and the corner brace section bar, and the strength of the glue injection corner brace is reduced.

Compared with the prior art, in the manufacturing equipment of the glue injection corner brace provided in this embodiment, since the height position of the spray gun assembly 200 is precisely controlled by the height adjusting device 300 in the manufacturing work of the glue injection corner brace, the lifting seat 350 drives the spray gun assembly 200 to move downwards under the action of the servo driving mechanism, so that the spray head 230 can move downwards to the bottom of the glue injection cavity of the corner brace profile, and the two-component resin is poured into the glue injection cavity. Because the component a and the component B of the two-component resin flow to the dispensing head 210 through the corresponding discharging pipes 110, respectively, and join at the dispensing head 210 and enter the static mixer 220 together, the component a and the component B can be uniformly mixed and fully react to generate the two-component resin, and the two-component resin flows from the nozzle 230 to the glue injection cavity, and meanwhile, as the amount of the two-component resin in the glue injection cavity increases, the height adjusting device 300 controls the nozzle 230 to gradually move upwards, so that the nozzle 230 can be prevented from contacting with and even being immersed in the two-component resin in the glue injection cavity, and the flow path of the two-component resin can be shortened, so that the component a and the component B can be mixed through the mixing unit in the process of flowing downwards along the glue injection cavity, and the pre-mixing reaction outside the glue injection cavity is not needed.

Therefore, the manufacturing equipment of the glue injection corner connector can avoid the problem that the strength of the glue injection corner connector is affected due to the fact that the connection effect between a resin component and a corner connector section bar is weak and the resin component and an alloy corner connector are easily separated due to the fact that the two-component resin is easy to be quickly solidified in the downward pouring process.

In some embodiments, as shown in fig. 2 and 3, the servo drive mechanism includes a support 340, a timing belt assembly, and a rotary drive 310.

Wherein, the hold-in range part sets up on support 340, and the output of rotary drive piece 310 is connected with the input of hold-in range part, and the loose end of hold-in range part is connected with lifting seat 350, and lifting seat 350 can be installed on support 340 through the slide rail slider pair, realizes that lifting seat 350 slides and connects in support 340 for lifting seat 350 can slide in the upper and lower direction relative support 340.

Specifically, the timing belt assembly includes a pulley 320 and a timing belt 330. The pulley 320 is mounted on the support 340 through a rotating shaft, so that the pulley 320 is rotatably connected to the support 340. The number of pulleys 320 is two, and the two pulleys 320 are arranged at a certain interval in the up-down direction. The synchronous belt 330 is wound between the two pulleys 320, and the gears and the synchronous belt 330 are in meshed connection. One side of the timing belt 330 may be fixedly coupled to the lifting seat 350 through a belt clamping block assembly. Of course, the support 340 may be further provided with a tensioning wheel for tensioning the timing belt 330.

The rotary driving member 310 includes a servo motor and a speed reducer. Wherein, the output shaft of the servo motor and the input shaft of the speed reducer can be connected in a key connection mode, and the output shaft of the speed reducer is connected with one of the belt pulleys 320. In this embodiment, the servo motor and the speed reducer are both located at the lower portion of the support 340, and the speed reducer is in driving connection with the pulley 320 located at the lower side. The servo motor is a forward and reverse rotation motor, and the output shaft of the servo motor can rotate clockwise or anticlockwise.

When the output shaft of the servo motor rotates clockwise, the belt wheel 320 rotates and can drive the synchronous belt 330 to operate, so that the lifting seat 350 drives the spray gun assembly 200 to ascend; when the output shaft of the servo motor rotates anticlockwise, the belt wheel 320 rotates reversely and drives the synchronous belt 330 to run reversely, so that the lifting seat 350 drives the spray gun assembly 200 to move downwards.

The servo driving mechanism adopts the above structure, and can precisely control the height position of the spray head 230.

It can be appreciated that in the process of manufacturing the glue injection corner connector, the manufacturing equipment of the glue injection corner connector can be installed on the supporting frame, the working platform is located below the supporting frame, and corner connector section bars located on the working platform can be fixed through a plurality of fixing frames or clamps and the like, so that the corner connector section bars are perpendicular to the working platform and are in a vertical state. Since the length of the angle pattern may be up to 3 meters, the servo drive drives the spray head 230 to move a distance greater than 3 meters.

Of course, the use of a high precision linear module for the servo drive is not precluded.

Because the flowmeter of the discharging pipe 110 and the servo driving mechanism are respectively and electrically connected to the control device, the control device receives the flow data collected by the flowmeter and controls the servo driving mechanism to stop running according to the flow data. The control device is configured to: and when the flow data acquired by the flowmeter exceeds the input set range, controlling the servo driving mechanism to stop. Furthermore, the manufacturing facility may be provided with an alarm, such as an audible and visual alarm, to which the control device is electrically connected.

It can be understood that in normal glue injection operation, if the data of the flowmeter is abnormal and is not within the set range, the situation that the spray gun assembly is blocked is likely to occur, then the control device immediately controls the servo driving mechanism to stop running, and simultaneously, the tank 100 stops delivering liquid, and the control valve and the pump of the discharge pipe 110 can be controlled to be closed. Moreover, the control device controls the alarm to work and timely informs the staff to check and maintain.

In some embodiments, as shown in FIG. 3, the servo drive mechanism further includes a swing arm 360.

One end of the swing arm 360 may be hinged to the elevating seat 350 through a hinge shaft so that the swing arm 360 can rotate about a hinge axis extending in the up-down direction, and the opposite end of the swing arm 360 is connected to the dispensing head 210.

So set up, the staff can apply certain effort to swing arm 360 to order to drive spray gun subassembly 200 to take place certain swing around the articulated department of swing arm 360 and elevating seat 350, adjust the angular position of spray gun subassembly 200 on the horizontal plane.

It will be appreciated that, since the manufacturing apparatus for the glue injection corner connector is located on a support frame, such as a steel structure platform frame, the working platform is located below the support frame, and a worker standing on the support frame can move the spray gun assembly 200 to the upper side of the corner connector profile by rotating the swing arm 360 and align to the glue injection cavity, and can also move the spray gun assembly 200 to approach the worker by rotating the swing arm 360, so as to perform inspection and maintenance.

Of course, an electric drive device may be provided and connected to the swing arm 360. The electric driving device may include a motor and a speed reducer, where the motor is a servo motor, and drives the swing arm 360 to automatically rotate by a certain angle through a synchronous belt structure.

In some embodiments, a stirring assembly and a heating assembly are provided within the canister 100 for containing component a.

Wherein, stirring subassembly is including motor, (mixing) shaft and stirring vane. The length direction of (mixing) shaft extends along the upper and lower direction, and stirring vane is equipped with the polylith to fixed setting is at the outer peripheral face of (mixing) shaft, and polylith stirring vane is the circumference and arranges, and motor drive (mixing) shaft is rotatory, lets stirring vane carry out stirring to the component A in the jar body 100 and handles, lets component A keep certain mobility. The tank body 100 is provided with a cover body so that the component A can be in a good sealing state, and the motor is arranged outside the containing cavity of the tank body 100 and can be arranged on the cover body, and the stirring shaft penetrates through the cover body.

The heating element may be a PTC heater, which is capable of heating the component a in the can 100 to provide a certain fluidity to the component a and to flow out through the discharge pipe 110.

In some embodiments, the dispensing head 210 is provided with a cleaning fluid inlet and a purge gas inlet. Wherein, the washing liquid import communicates in the cavity, and the washing liquid import is connected with the washing liquid pipeline, and the washing liquid pipeline is provided with the control valve. The purge gas inlet is communicated with the cavity, and is connected with a purge gas pipeline which is provided with a control valve. Furthermore, the tapping pipe 110 is also provided with a control valve.

After the two-component resin casting operation is completed, the dispensing head 210 or the entire spray gun assembly 200 may be cleaned with a cleaning fluid, and then purged with a purge gas such as nitrogen to remove the liquid remaining in the dispensing head 210 or the spray gun assembly 200.

In some embodiments, each static mixer 220 is jacketed with at least one idler assembly. The idler assembly includes four idler wheels 620, and the four idler wheels 620 are arranged in a circumferential arrangement around the static mixer 220.

It will be appreciated that each static mixer 220 may be equipped with one idler assembly or two or more idler assemblies. When the static mixer 220 stretches into the glue injection cavity of the corner brace section bar, the four guide wheels 620 are respectively contacted with the four inner wall surfaces of the glue injection cavity, so that the spray head 230 is located at the middle position of the glue injection cavity, and the problem that the upper surface of a resin component is uneven due to less double-component resin in the position, farthest from the spray head 230, of the glue injection cavity caused by the middle position offset of the spray head 230 relative to the glue injection cavity is avoided. Meanwhile, the positions of the static mixer 220 and the spray head 230 in the glue injection cavity do not need to be manually adjusted, and the operation difficulty is reduced. Moreover, the guide wheel 620 can play a guiding role, and the friction effect between the guide wheel 620 and the angle code section bar is weak, so that the long mixing unit can stably lift, and the situation that the structural stability of the injection molding work and the spray gun assembly 200 is affected due to the fact that the long mixing unit and the spray head 230 shake in the lifting process and collide with the inner wall surface of the injection cavity is avoided.

In one specific example, as shown in FIG. 4, the idler assembly includes sleeve 640, spring 650, slip ring 660, first link 610, second link 630, and idler 620.

Specifically, the sleeve 640 may be fixed to the outer peripheral surface of the static mixer 220 by an adhesive method, a screw structure, a fastening screw, or the like. The lower end of the first link 610 is installed at the lower portion of the sleeve 640 through a hinge shaft, and the first link 610 is provided with four and is uniformly arranged around the central axis of the sleeve 640. The guide pulley 620 is mounted at an upper end of the first link 610 through a hinge shaft. The central axis of the guide pulley 620 extends in a horizontal direction.

The sliding ring 660 is sleeved on the sleeve 640 and is slidingly connected with the sleeve 640 in the up-down direction. The lower end of the second link 630 is hinged to the sliding ring 660, the upper end of the second link 630 is hinged to the first link 610, and the hinge of the second link 630 and the first link 610 is located below the guide wheel 620 and above the hinge of the first link 610 and the sleeve 640. The number of the second links 630 may be four, corresponding to the four first links 610, respectively. Of course, each first link 610 may be configured with two second links 630.

The spring 650 is sleeved on the sleeve 640, and the spring 650 is positioned below the sliding ring 660. The lower end of the spring 650 is connected to the sleeve 640, and the upper end of the spring 650 is connected to the sliding ring 660. The sliding ring 660 automatically slides upward relative to the sleeve 640 under the elastic force of the spring 650. It will be appreciated that when first link 610 or guide wheel 620 is subjected to an external force, first link 610 will approach sleeve 640, causing sliding ring 660 to move downward and overcome the spring force of spring 650.

In this embodiment, the first link 610 makes a first acute angle with the central axis of the sleeve 640, the second link 630 makes a second acute angle with the central axis of the sleeve 640, and the first acute angle is less than the second acute angle. The lower end of the sleeve 640 is provided with a hinge portion to hinge with the first link 610, and the lower end of the spring 650 abuts against the hinge portion. The upper end of the sleeve 640 is provided with a limiting portion 641 to limit the sliding ring 660, thereby preventing the sliding ring 660 from being separated from the sleeve 640.

The stopper 641 may be mounted on the sleeve 640 by a screw structure. Then, after the disassembly limiting part 641, the first link 610, and the second link 630 are disassembled, the sliding ring 660 and the spring 650 can be taken out. The guide wheel assembly is arranged in such a way, and the assembly difficulty of the guide wheel assembly can be simplified. The hinge shaft of the guide wheel assembly may be a bolt. The idler assembly may be made of a plastic material.

With the above arrangement, when at least one of the four first links 610 is subjected to an external force, all of the first links 610 are drawn together, so that the horizontal distance between the guide wheel 620 and the sleeve 640 is reduced.

Because work platform is located the below of support frame, consequently, the staff stands on the support frame, can observe the injecting glue chamber of angle sign indicating number section bar. In the manufacturing process of the glue injection corner connector, the height adjusting device 300 drives the spray gun assembly 200 to move upwards to the position above the corner connector section bar, and the spray gun assembly and the glue injection cavity are arranged in a vertically opposite mode. The gun assembly 200 is then driven downward and into the glue injection cavity of the corner trim profile by the height adjustment assembly 300. When the guide wheels 620 extend into the glue injection cavity, the swing arm 360 can be controlled to rotate by a manual mode or an electric driving mode, and the positions of the static mixer 220 and the spray head 230 relative to the glue injection cavity are adjusted so that the four guide wheels 620 are respectively contacted with the four inner wall surfaces of the glue injection cavity correspondingly.

Under the condition of facing the glue injection cavities with different sizes, the guide wheel assemblies can all play a role, when the static mixer 220 stretches into the glue injection cavity, the first connecting rods 610 can be pressed by the angle code section bars to be close to the central axis of the static mixer 220, and due to the arrangement of the second connecting rods 630 and the sliding rings 660, all the first connecting rods 610 synchronously act to be close, so that the four guide wheels 620 respectively correspondingly abut against the four inner wall surfaces of the glue injection cavity. All of the guide wheels 620 are located in the same circle with the center located in the central axis of the static mixer 220. Then, the guide wheel assembly will perform a good guiding function during the continuous downward movement of the spray head 230, so that the spray head 230 and all static mixers 220 move downward smoothly. In addition, during the rising process of the nozzle 230 and all static mixers 220, the guide wheel 620 still presses against the inner wall surface of the glue injection cavity, and plays a guiding role, so that the two-component resin can stably flow out from the nozzle 230, and the glue injection effect is improved.

As shown in fig. 1 to 5, a manufacturing process of an injection molding corner key according to an embodiment of the second aspect of the present invention employs a manufacturing apparatus of an embodiment of the first aspect, and the manufacturing process includes the steps of:

step S1: the nozzle 230 is controlled to move downwards by the height adjusting device 300 and extend into the bottom of the glue injection cavity of the corner bracket profile.

It can be appreciated that the lifting base 350 drives the spray gun assembly 200 to move downwards under the action of the servo driving mechanism, so that the spray head 230 can move downwards to the bottom of the glue injection cavity of the corner bracket profile, and thus the pouring of the two-component resin can be realized from bottom to top along the glue injection cavity. By the design, the distance between the spraying opening of the spraying head 230 and the joint of the sprayed two-component resin and the corner pattern material is shortened, and the situation that the two-component resin is connected with the corner pattern material poorly due to rapid solidification is avoided.

Step S2: the nozzle 230 is controlled to pour the two-component resin into the injection cavity, and at the same time, the nozzle 230 is controlled to move up according to the injection condition by the height adjusting device 300.

The component a and the component B flow into the dispensing head 210 through the corresponding discharge pipes 110 to be joined and enter the mixing unit together, so that the component a and the component B flow spirally in the mixing unit, so that they can be uniformly mixed and fully reacted to generate a two-component resin, and the two-component resin flows from the nozzle 230 to the glue injection cavity.

Along with the progress of injecting glue work, the two-component resin volume in the injecting glue intracavity increases, and the upper surface of resin component risees, then, control shower nozzle 230 through height adjusting device 300 and shift up gradually, not only can avoid shower nozzle 230 and the two-component resin in the injecting glue intracavity to contact, bump or be submerged even, influence follow-up injecting glue work and go on, moreover, can also shorten the flow path of two-component resin after the production, thereby can avoid appearing the two-component resin and take place the solidification because of the flow path overlength down in the pouring down process, cause the connection effect between resin component and the angle code section bar not good, lead to resin component and alloy angle code to separate easily, and then influence the problem that the intensity of injecting glue angle code descends.

Step S3: and after the glue injection is finished, cutting the corner code section bars to manufacture a plurality of glue injection corner codes.

After the pouring work of the two-component resin is finished, a worker can take out the corner brace section bar subjected to glue injection treatment and cut the corner brace section bar through a cutting machine, so that a plurality of glue injection corner braces with uniform specifications are cut. By the design, daily output of the glue injection corner connector can be increased.

While the preferred embodiments of the present invention have been illustrated and described, the present invention is not limited to the embodiments, and various equivalent modifications and substitutions can be made by one skilled in the art without departing from the spirit of the present invention, and these are intended to be included in the scope of the present invention as defined in the appended claims.
