[0020] Beneficial effects:

[0021] 1. The present invention provides a glue delivery component. The glue inside the glue box can be kept in a molten state under the action of the first heating strip and the stirring mechanism. The molten glue enters the quantitative box through the bottom tube, and the amount of glue can be preliminarily limited. At the same time, the glue inside the quantitative box can flow out through the glue outlet pipe and the second solenoid valve. By controlling the second solenoid valve, the amount of glue flowing out through the glue outlet pipe can be controlled, so that it is convenient for the staff to accurately control the amount of glue. By providing the first adjustment component and the second adjustment component, the material on the top of the conveyor belt can be coated with glue longitudinally under the action of the first scraper, so that the glue can be coated for the first time, so that the thicker glue can be coated in multiple places, and then under the action of the second scraper, the glue can be coated horizontally, so that the glue can be coated for the second time, so that the glue can be evenly coated. At the same time, the distance between the first scraper and the material is slightly greater than the distance between the second scraper and the material. At the same time, the coating thickness of the material glue is limited by the second scraper, so that the glue can be evenly coated on the surface of the material;

[0022] 2. The present invention provides a temperature sensor. Under the action of the temperature sensor, the temperature inside the glue box can be monitored in real time, so that the glue can be kept in a molten state. By providing a first solenoid valve, the glue passes through the glue box and the bottom tube into the quantitative box. Under the action of the first solenoid valve, the bottom tube can be controlled. By providing a second solenoid valve, the glue inside the quantitative box flows through the glue outlet pipe. Under the action of the second solenoid valve, the glue outlet amount can be controlled again, so that the glue outlet amount can be accurate. By providing a cylinder, under the action of the cylinder, the position of the first scraper can be controlled, and the thickness of the glue applied on the top of the material can be controlled by the first scraper. By providing a positioning plate and a first spring, when the first scraper is disassembled and assembled, the positioning plate is pulled, and the positioning plate can drive the second connecting rod to move, so that the first spring is extended, and then The positioning rod is allowed to detach from the positioning hole, and the first scraper can be disassembled, which makes it convenient for the staff to disassemble and assemble the first scraper. By setting the rotating tube and the bottom rod, the motor is started. Under the action of the motor, the rotating tube can be driven to rotate, and then the rotating tube can drive the bottom rod to move. Under the action of the bottom rod, the positions of the first connecting plate and the second connecting plate can be adjusted. By setting the pull rod and the second spring, under the elastic force of the second spring, the pull rod can pass through the side plate into the interior of the second scraper, and then the second scraper can be positioned, which makes it convenient for the staff to position and disassemble and assemble the second scraper. By setting the collecting box, under the action of the second scraper, the glue applied on the top of the material can be applied, and some of the glue may fall off, and then the glue enters the interior of the collecting box through the inclined slot, and then is heated by the heating block to collect the glue.

[0032] The glue delivery component 5 is arranged on the top of the bracket 4.

The top of the bracket 4 is fixedly connected with the glue box 51, the bottom of the glue box 51 is connected with the bottom pipe 52, the bottom of the bottom pipe 52 is connected with the quantitative box 53, the quantitative box 53 is provided with a transparent plate 54 inside, and the front surface of the transparent plate 54 is provided with scale lines 55;

[0033] A first adjustment component 6, which is disposed on the top of the base 1, and includes an inclined plate 61, a first scraper 62 and a positioning plate 63; the inclined plate 61, the top of the base 1 is provided with an inclined plate 61, one side of the inclined plate 61 is provided with a first scraper 62, and the front surface and the rear surface of the first scraper 62 are both provided with positioning plates 63;

[0034] The second adjusting component 7 is arranged on the top of the base 1. The second adjusting component 7 includes a fixed plate 71, a screw mechanism 72, a motor 73 and a second scraper 74. The top of the base 1 is fixedly connected with the fixed plate 71, the screw mechanism 72 is arranged inside the fixed plate 71, the motor 73 is arranged outside the screw mechanism 72, and the second scraper 74 is arranged at the bottom of the motor 73.

[0035] In the specific implementation process, Figure 1 , Figure 2 and Figure 3 As shown, a first heating strip 8 is disposed on the inner wall of the glue box 51 , temperature sensors 9 are disposed on both sides of the inner wall of the glue box 51 , and a stirring mechanism 10 is disposed at the bottom of the inner cavity of the glue box 51 .

[0036] A first solenoid valve 11 is disposed on the outer side of the bottom tube 52 , and second heating strips 12 are disposed on both sides of the inner wall of the quantitative box 53 .

[0037] The bottom of the quantitative box 53 is connected to a rubber outlet pipe 13 , and a second solenoid valve 14 is arranged outside the rubber outlet pipe 13 .

[0038] The bottom of the glue box 51 is fixedly connected to the cylinder 15 , the piston rod of the cylinder 15 is fixedly connected to the mounting plate 16 , and the bottom of the mounting plate 16 is fixedly connected to the top of the inclined plate 61 .

[0039] It should be noted that: under the action of the first heating strip 8, the glue stored in the glue box 51 can be heated so that the glue can be kept in a molten state, thereby allowing the glue to flow out smoothly. At the same time, under the action of the stirring mechanism 10, the glue will not coagulate. When it is necessary to discharge glue, the first solenoid valve 11 is opened so that the glue can enter the quantitative box 53 through the bottom tube 52. At the same time, the staff observes the amount of glue in the quantitative box 53 through the transparent plate 54 and the scale line 55. When the glue reaches a certain amount, the solenoid valve 11 is closed. The first solenoid valve 11 allows the amount of glue inside the quantitative box 53 to be maintained constant, and at the same time, the second solenoid valve 14 is opened, so that the glue inside the quantitative box 53 can flow out through the glue outlet pipe 13, thereby facilitating the staff to accurately control the glue output through the first solenoid valve 11, the second solenoid valve 14 and the quantitative box 53. At the same time, when the staff needs to adjust the position of the first scraper 62, the cylinder 15 is started. Under the action of the cylinder 15, the first scraper 62 can be driven to move through the inclined plate 61, thereby adjusting the position of the first scraper 62.

[0040] refer to Figure 1 and Figure 3 As shown, the rear surface of the positioning plate 63 is fixedly connected to the first connecting rod 17 , the interior of the first scraper 62 is provided with a plug hole 18 used in conjunction with the first connecting rod 17 , and the rear surface of the positioning plate 63 is fixedly connected to the second connecting rod 19 .

[0041] A first spring 20 is welded inside the first scraper 62, one end of the first spring 20 is welded to the end of the second connecting rod 19 away from the positioning plate 63, a positioning rod 21 is fixedly connected to the rear surface of the positioning plate 63, and a positioning hole 22 used in conjunction with the positioning rod 21 is opened inside the inclined plate 61.

[0042] It should be noted that: when the first scraper 62 is used for a long time, the first scraper 62 may be damaged to a certain extent. When the first scraper 62 needs to be disassembled and replaced, first pull the positioning plate 63. When the positioning plate 63 moves, it can drive the first connecting rod 17 to slide inside the socket 18. At the same time, the second connecting rod 19 drives the first spring 20 to extend. After the positioning plate 63 moves to the specified position, the positioning rod 21 can be disengaged from the inside of the positioning hole 22, and then the first scraper 62 can be disengaged from the inclined plate 61, thereby facilitating the staff to replace and disassemble the first scraper 62.

[0043] refer to Figure 1 , Figure 4 and Figure 5 As shown, the bottom of the motor 73 is fixedly connected to a rotating tube 23, the internal thread of the rotating tube 23 is connected to a bottom rod 24, the bottom of the bottom rod 24 is fixedly connected to a first connecting plate 25, and both sides of the first connecting plate 25 are fixedly connected to second connecting plates 26.

[0044] The bottom of the first connecting plate 25 and the bottom of the second connecting plate 26 are both fixedly connected with a side plate 27, and a pull rod 28 is slidably connected inside the side plate 27. A second spring 29 is sleeved on the outer side of the pull rod 28, and one end of the second spring 29 is welded to the outer side of the pull rod 28.

[0045] It should be noted that: when it is necessary to adjust the distance between the second scraper 74 and the material, first start the motor 73. Under the action of the motor 73, the rotating tube 23 can be driven to rotate, and then when the rotating tube 23 rotates, the second scraper 74 can be driven to move through the first connecting plate 25 and the second connecting plate 26, so that the position of the second scraper 74 can be adjusted. When it is necessary to replace or disassemble the second scraper 74, first pull the pull rod 28 so that the pull rod 28 slides inside the side plate 27, and then the second spring 29 is extended, so that the pull rod 28 is separated from the inside of the second scraper 74, thereby facilitating the staff to disassemble or replace the second scraper 74.

[0046] refer to Figure 1 and Figure 6 As shown, a collecting box 30 is arranged on the top of the base 1 , a sliding bar 31 is fixedly connected to the front surface of the collecting box 30 , a heating block 32 is arranged on the inner wall of the collecting box 30 , and a chute 33 is fixedly connected to the rear surface of the collecting box 30 .

[0047] It should be noted that: when the second scraper 74 is operating normally, under the action of the screw mechanism 72, the second scraper 74 can move horizontally, so as to smear the glue on the surface of the material. Some glue may fall accidentally. Under the action of the inclined groove 33, the glue can pass through the inclined groove 33 to the inside of the collection box 30. Under the action of the heating block 32, the glue collected in the collection box 30 can be heated to prevent it from solidifying.

[0048] The working principle of the gluing control device of the hot melt adhesive laminating machine provided by the present invention is as follows:

[0049] When the staff needs to use this device to apply glue to the logistics, first place the material on the top of the conveyor belt 2. Under the action of the conveyor belt 2, the material first passes through the bottom of the glue box 51. At the same time, the staff starts the first heating strip 8 to work. Under the action of the first heating strip 8 and the stirring mechanism 10, the glue inside the glue box 51 can be kept in a molten state. The first solenoid valve 11 is opened, so that the glue can pass through the bottom tube 52 to enter the inside of the quantitative box 53. At the same time, the staff can observe the amount of glue inside the quantitative box 53 through the transparent plate 54 and the scale line 55, and then open the second solenoid valve 14. Under the action of the glue outlet pipe 13, the glue inside the quantitative box 53 can drip through the glue outlet pipe 13, so that the glue falls on the top of the material. At the same time, through the cylinder 15, under the action of the cylinder 15, the first scraper 62 and the material can be The distance between the materials can be quickly adjusted. After the distance of the first scraper 62 is adjusted, the motor 73 is started. Under the action of the motor 73, the rotating tube 23 can be driven to rotate, and then the rotating tube 23 can drive the bottom rod 24 to move, and then under the action of the bottom rod 24, the second scraper 74 can be driven to move, so that the distance between the second scraper 74 and the material can be adjusted. At the same time, the distance between the first scraper 62 and the material is slightly larger than the distance between the second scraper 74 and the material. The distance between the second scraper 74 and the material can limit the thickness of the glue coated on the top of the material. Under the action of the first scraper 62, the glue on the top of the logistics can be coated longitudinally. At the same time, under the action of the second scraper 74, the glue on the top of the material can be coated transversely, so that the glue on the top of the material can maintain a uniform thickness, which is convenient for the staff to control the thickness of the glue on the top of the material.
