A support frame is provided on the surface of the device frame, and wheels are provided on the surface of the support frame. The wheels rotate in relation to the inner wall of the support frame, and the surface of the wheels is aligned with the surface of the top position of the envelope body. In contact with each other, the surface of the equipment frame is provided with a spring assembly, which cooperates with the surface of the support frame. A fixing plate is installed on one side of the surface of the equipment frame. A dispensing head frame is installed on the surface of the fixing plate by screws.

Under the action of the fastening bolts, the U-shaped frame is installed on the surface of the equipment body. When the envelope body is conveyed to the surface of the conveyor belt, the envelope body moves to the bottom of the guide roller. During the conveying process, the envelope body drives the guide roller to rotate on the surface of the guide frame. At this time, the guide frame squeezes the elastic device, causing the elastic device to contract. Under the combined action of the guide frame and the elastic device, the surface of the envelope body is guided, realizing the function of guiding and feeding the envelope body by the dispensing equipment. This allows the dispensing equipment to position the feeding position of the envelope body during use, and at the same time, makes the positioning of the envelope body by the dispensing equipment more accurate during use.

[0013] 2. Equipped with a uniform dispensing mechanism, the user places the mounting plates at designated positions on the plate surface and tightens the mounting studs. The mounting plates are then installed on the plate surface. When the conveyor belt moves the envelope body, the envelope body drives the rotating wheel to rotate on the inner wall of the wheel frame. The rotating wheel is supported by the wheel frame and the fixed frame. The rotating wheel provides auxiliary guidance to the surface of the envelope body, ensuring smoother transport and reducing the likelihood of jamming. This allows for more uniform dispensing of adhesive onto the envelope surface, achieving the uniform dispensing function of the dispensing equipment. This ensures accurate dispensing to the sides of the envelope body and improves the overall dispensing effect. Attached Figure Description

A pressure sensor 111 (of which the model can be GPD series) is mounted on the surface of the glue tank 102. The output of the pressure sensor 111 is electrically connected to the input of the controller 11. A liquid inlet pipe 103 is mounted on the top surface of the glue tank 102 via screws, and the liquid inlet pipe 103 communicates with the interior of the glue tank 102. A liquid level sensor 110 is mounted on the inner wall of the glue tank 102. The sensor 110 can be a PY series model. The output terminal of the liquid level sensor 110 is electrically connected to the input terminal of the controller 11. A support frame 116 is provided on the surface of the equipment frame 101. A wheel 117 is provided on the surface of the support frame 116. The wheel 117 rotates with the inner wall of the support frame 116. The surface of the wheel 117 contacts the surface at the top of the envelope body 104. A spring assembly 115 is provided on the surface of the equipment frame 101. The spring assembly 115 cooperates with the surface of the support frame 116. A fixing plate 12 is installed on one side of the equipment frame 101. A dispensing head frame 114 is installed on the surface of the fixing plate 12 by screws. A dispensing head frame 114 is installed inside the dispensing head frame 114. The dispensing head assembly 106 is located above the envelope body 104. An assembly frame 13 is mounted on the surface of the fixing plate 12 by screws. A laser positioning sensor 14 is mounted on the surface of the assembly frame 13. The laser positioning sensor 14 can be of the LDM series.

[0021] Furthermore, such as Figure 2 and Figure 3As shown, the surface of the plate 119 is provided with a uniform dispensing mechanism 2. The uniform dispensing mechanism 2 is composed of a mounting plate 21, a mounting stud 22, a rotating wheel 23, a wheel frame 24 and a fixing frame 25. The surface of the plate 119 is provided with mounting plates 21 at equal intervals. The surface of the mounting plate 21 is threaded with mounting studs 22. One end of the mounting stud 22 passes through the mounting plate 21 and is threadedly fastened to the surface of the plate 119. The surface of the mounting plate 21 at the bottom position is provided with a fixing frame 25. The surfaces of the fixing frame 25 on both sides are provided with wheel frames 24. The surface of the wheel frame 24 is provided with a rotating wheel 23. The rotating wheel 23 and the surface of the wheel frame 24 rotate and cooperate with each other. The surface of the bottom position of the rotating wheel 23 is in contact with the surface of the envelope body 104.

[0022] In practice, the user places the mounting plates 21 at designated positions on the surface of the plate body 119, and then tightens the mounting studs 22 on the surface of the mounting plates 21. Under the action of the mounting studs 22, the mounting plates 21 are installed on the surface of the plate body 119. When the conveyor belt 105 drives the envelope body 104 to move, the envelope body 104 drives the rotating wheel 23 to rotate on the inner wall of the wheel frame 24. Under the joint action of the wheel frame 24 and the fixed frame 25, the rotating wheel 23 is supported. Under the action of the rotating wheel 23, the surface of the envelope body 104 can be guided, and the envelope body 104 can be conveyed more smoothly and less prone to jamming. This makes the dispensing head assembly 106 more uniform when dispensing glue to the surface of the envelope body 104, so as to realize the function of uniform glue dispensing of the dispensing equipment.

[0023] Furthermore, such as Figure 2 and Figure 4 As shown, the surfaces of the device body 1 and the envelope body 104 are provided with a guiding feeding mechanism 3. The guiding feeding mechanism 3 consists of a U-shaped frame 31, a guide roller 32, a fastening bolt 33, a mounting block 34, a guide frame 35, and a spring device 36. The U-shaped frame 31 is provided on the surface at the top position of the device body 1. Mounting blocks 34 are installed on both sides of the U-shaped frame 31. Fastening bolts 33 are threadedly connected to the surface of the mounting blocks 34. One end of the fastening bolt 33 passes through the mounting block 34 and is threadedly fastened to the surface of the device body 1. The guide frame 35 is provided on the inner side of the U-shaped frame 31. The guide roller 32 is provided on the inner wall of the guide frame 35. The surfaces of the guide roller 32 and the guide frame 35 rotate and cooperate with each other. The surface of the guide roller 32 is in contact with the surface of the envelope body 104. The inner wall of the U-shaped frame 31 is provided with a spring device 36. The surface at the bottom position of the spring device 36 is fixed to the surface at the top position of the guide frame 35.

[0024] In practice, the user places the U-shaped frame 31 on the surface of the equipment body 1 and then tightens the fastening bolts 33 on the surface of the mounting block 34. Under the action of the fastening bolts 33, the U-shaped frame 31 is installed on the surface of the equipment body 1. When the envelope body 104 is conveyed to the surface of the conveyor belt 105, the envelope body 104 moves to the bottom of the guide roller 32. During the conveying process, the envelope body 104 drives the guide roller 32 to rotate on the surface of the guide frame 35. At this time, the guide frame 35 squeezes the elastic device 36, causing the elastic device 36 to contract. Under the combined action of the guide frame 35 and the elastic device 36, the surface of the envelope body 104 is guided. Moreover, under the action of the guide roller 32, the position of the envelope body 104 during feeding can be further guided and limited, so as to realize the function of guiding and feeding the envelope body 104 by the dispensing equipment.

[0025] Working Principle: In use, the device body 1 is first placed in the designated position. The user introduces glue into the glue tank 102 through the inlet pipe 103. The level sensor 110 monitors the glue level in real time, allowing for timely replenishment of glue within the glue tank 102. The pressure sensor 111 monitors the pressure inside the glue tank 102 and the inlet pipe 112 in real time, ensuring stable dispensing pressure and consistent glue application by the dispensing head assembly 106 to the surface of the envelope body 104. The dispensing head assembly 106 then applies glue to the surface of the envelope body 104. Subsequently, the envelope body 104, to be dispensed, moves to the surface of the conveyor belt 105. The user operates the controller 11, which controls the drive motor 108 to operate, driving the conveyor belt 105. The rotating shaft 109 rotates, driving the conveyor belt 105 to move and transport the envelope body 104 on the surface of the conveyor belt 105. When the envelope body 104 moves to the bottom of the wheel 117, the wheel 117 rotates on the inner wall of the support frame 116. At this time, the support frame 116 compresses the spring assembly 115, causing the spring assembly 115 to contract, so that the envelope body 104 can be smoothly transported on the surface of the conveyor belt 105. Subsequently, the position of the envelope body 104 is sensed in real time by the laser positioning sensor 14 on the surface of the assembly frame 13, and the signal is sent to the controller 11 to ensure the consistency of the glue dispensing position on the surface of the envelope body 104. When the conveyor belt 105 drives the envelope body 104 to move, the glue dispensing head assembly 106 can dispense glue onto the surface of the envelope body 104.

[0026] Subsequently, the user places the U-shaped frame 31 on the surface of the equipment body 1 and tightens the fastening bolts 33 on the surface of the mounting block 34. Under the action of the fastening bolts 33, the U-shaped frame 31 is installed on the surface of the equipment body 1. When the envelope body 104 is conveyed to the surface of the conveyor belt 105, the envelope body 104 moves to the bottom of the guide roller 32. During the conveying process, the envelope body 104 drives the guide roller 32 to rotate on the surface of the guide frame 35. At this time, the guide frame 35 compresses the elastic device. 36 causes the elastic device 36 to contract, and under the combined action of the guide frame 35 and the elastic device 36, it guides the surface of the envelope body 104. Moreover, under the action of the guide roller 32, it can further guide and limit the position of the envelope body 104 during feeding, so as to realize the function of guiding and feeding the envelope body 104 by the dispensing equipment. This allows the dispensing equipment to position the feeding position of the envelope body 104 during use, and at the same time, it makes the positioning of the envelope body 104 by the dispensing equipment more accurate during use.

[0027] Subsequently, the user places the mounting plates 21 at designated positions on the surface of the plate 119, and then tightens the mounting studs 22 on the surface of the mounting plates 21. Under the action of the mounting studs 22, the mounting plates 21 are installed on the surface of the plate 119. When the conveyor belt 105 drives the envelope body 104 to move, the envelope body 104 drives the rotating wheel 23 to rotate on the inner wall of the wheel frame 24. The rotating wheel 23 is supported by the wheel frame 24 and the fixed frame 25. Under the action of the rotating wheel 23, the surface of the envelope body 104 can be guided, and the envelope body 104 can be conveyed more smoothly and less prone to jamming. This makes the dispensing head assembly 106 more uniform when dispensing glue on the surface of the envelope body 104, so as to realize the function of uniform glue dispensing of the dispensing equipment. This ensures the accuracy of glue dispensing on the side position of the envelope body 104 when the dispensing equipment is used, and at the same time, makes the glue dispensing effect better when the dispensing equipment is used, thus completing the use of the dispensing equipment.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
