Background
In the field of furniture processing, furniture mainly made of boards is often provided with a sealing strip through sealing a sawed surface, so that the appearance is attractive, the edges of the boards are protected from being affected by moisture in the environment, and the sealing effect depends on the quality of glue and glue. To the use of rubber coating mechanism, the intelligent control of glue use amount, the use selection of many money glue colours and the clearance convenience of glue all influence customer's use and experience and the efficiency of rubber coating banding.
The glue spreading mechanism of the conventional edge bonding machine generally comprises EVA and PUR, the various glue spreading performances of the PUR glue are superior to those of the EVA, and along with the price reduction of the PUR, the market demand on the PUR glue spreading mechanism is greatly increased, so that the practicability requirement on the PUR glue spreading mechanism is higher and higher. The conventional edge bonding machine in the prior art generally adopts a double-glue-pot mechanism or a quick glue changing and pre-dissolving mechanism, and the double-glue-pot mechanism is convenient to switch but occupies a large space; the waiting time after the glue pot is switched by the quick glue changing and pre-dissolving mechanism is longer, and glue of another color is remained in the pre-dissolving mechanism.
The glue amount is as follows: the conventional edge bonding machine glue coating mechanism performs glue coating and edge bonding treatment on the plate of the plate-type furniture by using a glue coating shaft, the glue coating shaft coats hot melt glue on the edge of the plate in a rotating mode, and the glue coating amount is controlled by the opening and closing size between a glue door and the glue coating shaft.
Color switching: when the glue coating mechanism of the conventional edge bonding machine is used for replacing glue of another color, the glue coating mechanism is usually realized by adopting a quick glue replacing and pre-melting mechanism, a glue pot with a glue coating function is arranged below the glue pot, a pre-melting mechanism for storing glue particles and preheating the glue is arranged above the glue pot, and the glue pot at the bottom is quickly replaced to realize the switching between the glue of different colors. But the waiting time after the glue pot is switched is longer, and glue of another color is remained on the part of the pre-melting glue mechanism, so that the production efficiency is greatly reduced.
Cleaning a rubber door: when the gluing mechanism of the conventional edge bonding machine uses the gluing shaft to glue and edge bond the plate of the plate-type furniture, the hot melt adhesive is more and more adhered after being heated for a long time, the adhesive is adhered to the edge of the glue outlet of the glue door for a long time, and the adhesive at the edge of the glue door is accumulated more and more, so that the glue outlet of the gluing shaft is unevenly distributed, and the performance and the quality of the plate after edge bonding are influenced. In the prior art, the two air cylinders can only be used for respectively controlling the opening and closing of the two rubber doors, and the rubber doors are opened instantly to take away glue conglomerations at the rubber doors and other objects blocked by the rubber doors, such as particles and dust of other plates.
Cleaning a sol box: after the gluing and edge sealing treatment of the plate is finished, a part of glue is usually remained in the sol box, when the glue box is used next time, the remained part of glue can block a glue outlet pipe of the sol box, and an existing conventional edge sealing machine generally removes a glue pot for cleaning. However, the removal of the glue pot for cleaning is time-consuming and labor-consuming, and the production efficiency is affected.
A guide plate: the guider of conventional bag sealer rubber coating mechanism after live time for a long time often can appear the not hard up condition of deflector, leads to the deflector work unstable, influences the banding effect, probably consequently even the condition that panel collided with the rubber coating axle appears.

In addition, because the device is not provided with a glue pot in the traditional sense, the device also has the function of cleaning-free of the glue pot, and the cleaning of the glue pot is not needed. The first glue injection elbow 1 or the second glue injection elbow 37 is directly connected with a glue gun, the first pneumatic needle valve 16 and the second pneumatic needle valve 38 are used for directly controlling two kinds of glue with different colors to enter the glue dissolving box 9, the first pneumatic needle valve 16 and the second pneumatic needle valve 38 are used for controlling the glue to flow into the through holes of the first copper sleeve 30 and the second copper sleeve 43, and the same glue outlet pipeline 31 is shared in the glue dissolving box 9.
Specifically, in this embodiment scheme, the rubber coating mechanism during operation, when glue of gluing rifle (not shown in the figure) was injected toward first injecting glue elbow 15 or second injecting glue elbow 37, glue can be through inside sol box 9, is equipped with two first heating rods 1 in the sol box, and first heating rod 1 is used for heating sol box to by the temperature stability of thermocouple 29 cooperation control sol box 9, prevent that the interior glue of sol box 9 from condensing into a mass. The glue can flow out to one side of the glue box 9 close to the glue coating shaft 7 through the first copper sleeve 30, the connecting hole 39 and the glue outlet pipeline 31. The gluing shaft 7 is internally provided with a second heating rod 25, the second heating rod 25 is sleeved inside the positioning sleeve 22 and is heated by the fastening screw 23, and the second heating rod 25 extends into the gluing shaft to heat, so that the temperature stability of the gluing shaft is ensured. Because the glue spreading shaft 7 rotates during the operation, the flowing glue rotates along the glue spreading shaft 7 and passes through the gap (i.e. the glue door opening) between the glue door 18 and the glue spreading shaft 7, the glue spreading amount can be controlled by controlling the glue door 18 opening (as shown in figure 3 a), and when a wood board passes through, the glue can be uniformly coated on the wood board. The upper end of the gluing shaft 7 is provided with an upper cover 2; the upper cover 2 is provided with a cylinder mounting seat 3; the cylinder 4 is mounted on the cylinder mounting seat 3; the lower end of the gluing shaft 7 is provided with a support 17 for supporting the glue dissolving box 9.

Specifically, in the solution of this embodiment, the present invention creates a single glue door structure, that is, only one glue door 18 controls the glue discharging amount. Since no glue pot is provided, and how much glue is needed, the glue gun is used to add the glue, the glue door 18 is designed to be in an open state in a normal state, as shown in fig. 3a, which shows the open state of the glue door. Namely, the shaft of the air cylinder 4 is always in an extended state, and the connecting rod 6 in fig. 1 can be controlled to rotate clockwise by a certain angle by taking the rubber door 18 as a center. When the cylinder 4 extends out, the end surface of the adjusting nut 21 is tightly attached to the rear end of the cylinder, so that the size of the glue outlet amount can be adjusted by adjusting the position of the adjusting nut 21. When the adjusting nut 21 is screwed in, the extending shaft of the air cylinder 4 is shortened, the connecting rod 6 rotates clockwise, the distance between the opening of the glue door, namely the tangent of the glue door 18, and the glue coating shaft is increased, and the glue coating amount is increased; when adjusting nut 21 was twisted out, cylinder 4 projecting shaft became long, and connecting rod 6 anticlockwise rotation glues the door opening and glues the tangent line of door 18 promptly and the distance of rubber coating axle reduces, and the rubber coating volume reduces. After the adjustment is completed, the position of the adjusting nut 21 is fixed by the locking nut 26.
Specifically, in this embodiment scheme, single rubber door launches the clear glue: when the glue coating shaft 7 is used for a long time, the glue at the glue coating door 18 on the glue coating shaft 7 can be bonded into a lump or be stained with sawdust or dust and other things which can block the glue coating door 18. When the glue door is in work, under the condition that the glue coating shaft 7 rotates, the shaft end of the control cylinder 4 contracts instantly at intervals to drive the connecting rod 6 to rotate clockwise, the opening of the glue door 18 can be increased instantly, as shown in figure 3b, the ejection of the glue door is instantly shown, and a blockage adhered to the glue door 18 is taken away instantly, so that the glue at the glue door 18 is agglomerated and blocked.
Specifically, in the embodiment, after the glue applying mechanism stops working, the glue gun stops injecting glue, and the glue applying shaft 7 is used up. When the gluing mechanism is closed, part of glue can be remained on the gluing shaft 7, and at the moment, the glue can flow into a glue receiving box (not shown in the figure) arranged below along the arranged glue guiding plate 8. The glue outlet pipe 31 and the connecting hole 39 inside the glue box 9 still have the possibility of leaving a part of glue inside, causing blockage. At the moment, people only need to reasonably use a cylindrical tool to stretch into and out of the glue pipeline 31 and poke out the glue in the glue pipeline, and parts do not need to be additionally detached for cleaning. In addition, one side of the sol box 9 is also provided with an opening, the opening is provided with a round cup 24, when the connecting hole 39 in the sol box 9 is blocked, the round cup 24 can be unscrewed, and a cylindrical tool is used to extend into the opening to poke the blocking glue in the inner part.
Specifically, in this embodiment, glue amount intelligent control: as shown in figure 1, a connecting plate 12 is attached to a heat insulation plate 45 and installed on a glue dissolving box 9, a photoelectric sensor 10 (a reflection type photoelectric sensor is adopted in the invention, namely, the glue adding state is determined by setting the distance of the photoelectric sensor for receiving reflected light, when the photoelectric sensor cannot receive the reflected light, a green light is lighted, when glue accumulated at a glue door is enough, a knob is adjusted to enable the glue to be just lighted in a red light state) is attached to the heat insulation plate 11 and installed on the connecting plate 12, and the design ensures that the photoelectric sensor 10 is prevented from being influenced by high temperature on the glue dissolving box 9 and is prevented from being damaged. When the glue coating is carried out, the photoelectric sensor 10 is turned on, and the photoelectric sensor 10 emits a light to the direction of the glue coating shaft 7. When the glue amount at the glue inlet of the glue coating shaft 7 and the glue door 18 is large enough, light rays can be blocked by the glue, the photoelectric sensor 10 is lighted in red at the moment, a signal for stopping glue adding of the system is given, and the glue gun is controlled to stop glue adding at the moment; when the glue amount at the glue inlet of the glue coating shaft 7 and the glue door 18 is reduced and is too small to block light, the photoelectric sensor 10 at the moment is turned on to be green, the system receives a glue-free signal, and the glue gun is controlled to start to add glue at the moment. The glue spreading mechanism realizes intelligent control of glue amount, so that the glue amount is guaranteed to be kept in a relatively stable state all the time, and the edge sealing effect of the plate is guaranteed.
Specifically, in this embodiment, the fixed guider: as shown in figure 2, a guide 14 is arranged at the feeding position at one side of the gluing shaft 7, an adjusting block 13 is fixed on the guide 14, and an adjusting screw 20 is arranged on the adjusting block. One end of an adjusting screw 20 is locked into the internal thread hole of the sol box 9, and the other end is sleeved on the adjusting block 13; the two nuts are screwed and fixed on the adjusting screw 20, and when the adjusting screw 20 advances, the guide 14 can synchronously advance, so that the vertical distance between the guide 14 and the gluing shaft 7 can be adjusted. When the plate is coated with glue, the guide plate is always aligned with the edge of the plate, so that the glue coating shaft cannot collide with the plate. In addition, the glue coating amount of the plate can be adjusted by adjusting the vertical distance between the guide 14 and the glue coating shaft 7. After the guide plate is adjusted, the guide 14 is fixed by the locking screw 19. The advantage of this design over conventional guides is that it enables the guide 14 to be used in a stable and appropriate condition for a long period of time without loosening and without compromising the sealing effect.
