A belt body 1103 is fitted onto the surface of the pulleys 1102, and the surface of the belt body 1103 interacts with the surface of the pressure roller assembly 1102. The surfaces of 01 are in contact. A drive assembly 1104 is installed on the inner wall of the equipment bracket 10. The drive assembly 1104 can be a JO series drive motor. The input end of the drive assembly 1104 is electrically connected to the output end of the controller 11. The drive assembly 1104 is used to drive the transmission of the pressure roller assembly 1101. A baffle plate 15 for blocking the cardboard 14 of the envelope is installed on the inner wall of the equipment bracket 10 by screws. The position of the baffle plate 15 can be adjusted on the surface of the equipment bracket 10. A frame 17 is installed on the surface of the equipment base 1. Two sets of pressure rollers 16 are arranged on the inner side of the frame 17. A fixing rod 118 is installed on the surface of the top position of the frame 17. The surface of the fixing rod 118 is sleeved with A sleeve 119 is connected to a fixed rod 118 via fastening nails 120. A bottom conveyor belt assembly 116 is mounted on the surface of the sleeve 119. An adjusting rod 117 is provided on the surface of the bottom conveyor belt assembly 116. The adjusting rod 117 slides against the inner wall of the bottom conveyor belt assembly 116. A first scale line 122 is mounted on the surface of the adjusting rod 117. The bottom conveyor belt assembly 116 and the adjusting rod 117 are connected via nail bodies 121. A connecting frame 18 is mounted on the surface of the adjusting rod 117. A rotating pressure roller 19 is provided on the surface of the connecting frame 18 for pressing between the cardboard envelope 14 and the soft cardboard envelope 12. The rotating pressure roller 19 rotates against the surface of the connecting frame 18.

[0025] Furthermore, such as Figure 2 and Figure 5As shown, the pressure roller 16 and the frame 17 are provided with a rolling mechanism 2. The rolling mechanism 2 includes a second scale line 21, a fixed plate 22, a fixed screw 23, an adjusting screw 24, a fastening bolt 25, and a wheel frame 26. The surface of the pressure roller 16 is provided with a wheel frame 26, which rotates with the surface of the pressure roller 16. The inner wall of the frame 17 is provided with a fixed plate 22, and the surface of the fixed plate 22 is provided with a fixed screw 23. The bottom end of the fixed screw 23 extends to the bottom of the fixed plate 22. The surface of the fixed screw 23 is threaded with an adjusting screw 24, which rotates with the surface of the wheel frame 26. The adjusting screw 24 and the fixed screw 23 are connected by a fastening bolt 25. The surface of the frame 17 is provided with a second scale line 21.

[0026] During implementation, the user loosens the fastening bolt 25 on the surface of the adjusting screw 24, and then rotates the adjusting screw 24. Under the threaded engagement between the adjusting screw 24 and the fixing screw 23, the adjusting screw 24 moves up and down. When the adjusting screw 24 moves, it drives the wheel frame 26 and the pressure roller 16 to move up and down to the desired position. By observing the scale value of the wheel frame 26 corresponding to the second scale line 21, the user can accurately adjust the height position of the pressure roller 16. After the adjustment is completed, the fastening bolt 25 on the surface of the adjusting screw 24 is tightened. Under the action of the fastening bolt 25, the adjusting screw 24 and the fixing screw 23 are fixed, thereby fixing the position of the pressure roller 16, so as to realize the function of the feeding equipment rolling between the envelope cardboard 14 and the envelope soft cardboard 12.

[0027] Furthermore, such as Figure 3 As shown, the surfaces of the feeding rack 13 and the envelope cardboard 14 are provided with a highly versatile mechanism 4. The highly versatile mechanism 4 consists of a stud 41, an adjusting groove 42, a third scale line 43, a limiting plate 44, and a guide roller 45. Two sets of limiting plates 44 are symmetrically arranged on the surface of the feeding rack 13. The limiting plates 44 are located on both sides of the envelope cardboard 14. Multiple sets of guide rollers 45 are arrayed on the inner wall of the limiting plate 44. The guide rollers 45 rotate and cooperate with the inner wall of the limiting plate 44. The surface of the guide rollers 45 is in contact with the surface of the envelope cardboard 14. Two sets of adjusting grooves 42 are symmetrically opened on the surface of the feeding rack 13. The adjusting grooves 42 slide and cooperate with the surface of the limiting plate 44. The adjusting grooves 42 and the limiting plate 44 are connected by studs 41. The surface of the feeding rack 13 is equipped with a third scale line 43.

[0028] During implementation, the user loosens the studs 41 on the surface of the limiting plate 44 and then pulls the limiting plate 44, causing it to slide inside the adjusting groove 42. The adjusting groove 42 guides the limiting plate 44. By observing the third scale line 43 on the surface of the feeding rack 13, the user can precisely adjust the position of the limiting plate 44 so that the envelope cardboard 14 can be placed between the limiting plates 44. The limiting plates 44 can limit the position of the envelope cardboard 14. After adjustment, the user tightens the studs 41 on the surface of the limiting plate 44 to fix the limiting plate 44 to the surface of the feeding rack 13. Subsequently, when the envelope cardboard 14 is picked up, it will drive the guide roller 45 to rotate on the inner wall of the limiting plate 44. Under the action of the guide roller 45, the envelope cardboard 14 is picked up more smoothly without jamming, thus realizing the function of feeding envelope cardboard 14 of different widths.

[0029] Furthermore, such as Figure 2 As shown, the equipment support 10 and the surface of the adjusting base plate 115 are provided with an adjusting feeding mechanism 3. The adjusting feeding mechanism 3 includes a guide groove 31, a holding groove 32, an electric push rod 33 and a guide block 34. The inner wall of the equipment support 10 is provided with a holding groove 32. An electric push rod 33 is installed inside the holding groove 32. The electric push rod 33 can be of the DG series. The input end of the electric push rod 33 is electrically connected to the output end of the controller 11. The output end of the electric push rod 33 is fixed to the surface at the bottom of the adjusting base plate 115. The surface of the equipment support 10 is provided with two sets of guide grooves 31, which are located on both sides of the holding groove 32. A guide block 34 is provided inside the guide groove 31. The guide block 34 slides against the inner wall of the guide groove 31. The surface of the guide block 34 is fixed to the surface of the adjusting base plate 115.

[0030] During implementation, the electric push rod 33 inside the holding tank 32 is controlled to work. Under the action of the electric push rod 33, the adjusting base plate 115 moves up and down. At this time, the adjusting base plate 115 drives the guide block 34 to slide inside the guide groove 31. Under the joint action of the guide groove 31 and the guide block 34, the adjusting base plate 115 is guided. When the adjusting base plate 115 is adjusted to the required height position, the controller 11 controls the electric push rod 33 to stop working, thereby fixing the position of the adjusting base plate 115 on the inner wall of the equipment support 10, so that the distance between the bottom conveyor belt group 116 and the belt body 1103 can be fixed, so as to realize the function of adjusting the feeding of the feeding equipment.

[0031] Working Principle: In use, first place the equipment base 1 in the designated position. The user places the envelope cardboard 14 to be fed onto the surface of the feeding rack 13. At this time, the surface of the bottom envelope cardboard 14 is in contact with the surface of the feeding belt assembly 113. By adjusting the position of the baffle plate 15 on the surface of the equipment support 10, the user can block and limit the feeding of the envelope cardboard 14. Simultaneously, the user can control the number of envelope cardboard sheets fed each time. The controller 11 controls the operation of the board-retrieving assembly 114 and the feeding belt assembly 113. Under the action of the feeding belt assembly 113, the envelope cardboard 14 is retrieved; under the action of the board-retrieving assembly 114, the bottom envelope cardboard 14 is retrieved, thus... The bottom envelope cardboard 14 is fed onto the surface of the bottom conveyor belt assembly 116. Then, the controller 11 controls the drive assembly 1104 to operate, which in turn drives the pulley 1102 to rotate. The pulley 1102 then drives the belt body 1103, which in turn feeds the envelope cardboard 14 between the belt body 1103 and the bottom conveyor belt assembly 116. The bottom conveyor belt assembly 116 facilitates smoother feeding of the envelope cardboard 14. Subsequently, the conveying assembly 110 feeds the envelope soft cardboard 12, placing the envelope cardboard 14 onto the surface of the corresponding envelope soft cardboard 12. Because the drive assembly 1104 and the drive assembly 110 work synchronously, the cardboard 14 can be accurately fed onto the surface of the soft cardboard 12. Then, the user adjusts the height of the rotating pressure roller 19 according to the dimensions and thickness of the cardboard 14 and soft cardboard 12. The user loosens the fastening pins 120 on the surface of the sleeve 119 and pulls the sleeve 119 up and down to adjust the height of the rotating pressure roller 19. Then, the user loosens the nails 121 on the surface of the bottom conveyor belt assembly 116, causing the first scale line 122 to slide along the inner wall of the bottom conveyor belt assembly 116. The user observes the side of the bottom conveyor belt assembly 116 corresponding to the first scale line 122. The scale value of 2 allows for precise adjustment of the position of the adjusting rod 117, enabling the adjusting rod 117 to drive the connecting frame 18 and the rotating pressure roller 19 to the desired height. Subsequently, the user tightens the nail 121 on the surface of the bottom conveyor belt assembly 116, which fixes the adjusting rod 117 to the surface of the bottom conveyor belt assembly 116. When the cardboard envelope 14 and the soft cardboard envelope 12 pass the bottom of the rotating pressure roller 19, the rotating pressure roller 19 will rotate on the surface of the connecting frame 18. Under the action of the rotating pressure roller 19, the surfaces of the cardboard envelope 14 and the soft cardboard envelope 12 are rolled, which can roll the cardboard envelope 14 onto the surface of the soft cardboard envelope 12.

[0032] Subsequently, since the widths of the envelope cardboard 14 vary, the user needs to adjust the position between the limiting plates 44. The user loosens the studs 41 on the surface of each limiting plate 44 and then pulls the limiting plate 44, causing it to slide within the adjusting groove 42. The adjusting groove 42 guides the limiting plate 44. By observing the third scale line 43 on the surface of the feeding rack 13, the user can precisely adjust the position of the limiting plates 44, ensuring the envelope cardboard 14 can be placed between them. The limiting plates 44 effectively limit the position of the envelope cardboard 14. After adjustment, the... Users can fix the limiting plate 44 to the surface of the feeding rack 13 by tightening the studs 41 on the surface of the limiting plate 44. Then, when the envelope cardboard 14 is picked up, the envelope cardboard 14 will drive the guide roller 45 to rotate on the inner wall of the limiting plate 44. Under the action of the guide roller 45, the envelope cardboard 14 is picked up more smoothly without jamming, so as to realize the function of feeding the feeding equipment to the envelope cardboard 14 of different widths. This makes the feeding equipment more versatile in use.

[0033] Subsequently, since the thickness of the envelope cardboard 14 varies, the distance between the bottom conveyor belt assembly 116 and the belt body 1103 needs to be adjusted during use to ensure the smooth passage of the envelope cardboard 14. Specifically, the controller 11 controls the electric push rod 33 inside the holding slot 32 to operate. Under the action of the electric push rod 33, the adjusting base plate 115 moves up and down. At this time, the adjusting base plate 115 drives the guide block 34 to slide inside the guide groove 31. Under the combined action of the guide groove 31 and the guide block 34, the envelope cardboard 14 passes smoothly through the conveyor belt assembly 116 and the belt body 1103. The adjustable base plate 115 is used for guidance. When the adjustable base plate 115 is adjusted to the required height position, the controller 11 controls the electric push rod 33 to stop working, thereby fixing the position of the adjustable base plate 115 to the inner wall of the equipment support 10. This fixes the distance between the bottom conveyor belt assembly 116 and the belt body 1103, enabling the feeding equipment to adjust the feeding function. This allows the feeding equipment to adjust the distance between the bottom conveyor belt assembly 116 and the belt body 1103 according to the thickness of the envelope cardboard 14, while ensuring that only one envelope cardboard 14 can be fed at a time. Users can install laser positioning sensors at corresponding positions to make the adjustment of the adjustable base plate 115 more precise. When the adjustable base plate 115 is adjusted to the required position, the laser positioning sensor senses the position of the adjustable base plate 115 and sends a signal to the controller 11, which automatically controls the electric push rod 33 to stop working.

[0034] Subsequently, when the conveying assembly 110 moves the cardboard envelope 14 and the soft cardboard envelope 12 to below the pressure roller 16, the pressure roller 16 can roll the surfaces of the cardboard envelope 14 and the soft cardboard envelope 12 again to ensure the feeding effect of the cardboard envelope 14. Since the cardboard envelope 14 has different thicknesses, the user needs to adjust the height of the pressure roller 16. The user loosens the fastening bolt 25 on the surface of the adjusting screw 24 and then rotates the adjusting screw 24. Under the threaded engagement between the adjusting screw 24 and the fixing screw 23, the adjusting screw 24 moves up and down. When the adjusting screw 24 moves, it drives the wheel frame 26 and the pressure roller 16. After moving up and down to the desired position, the user can precisely adjust the height of the pressure roller 16 by observing the scale value of the wheel frame 26 corresponding to the second scale line 21. After adjustment, tighten the fastening bolt 25 on the surface of the adjusting screw 24. Under the action of the fastening bolt 25, the adjusting screw 24 and the fixing screw 23 are fixed, thereby fixing the position of the pressure roller 16. This enables the feeding equipment to roll between the envelope cardboard 14 and the envelope soft cardboard 12, resulting in a better feeding effect when the envelope cardboard 14 is fed onto the surface of the envelope soft cardboard 12. This makes the feeding equipment more practical and completes the use of the feeding equipment.
