Description

Technical Field

[0001] This utility model relates to the field of envelope production technology, specifically to a device for applying adhesive and attaching release paper to the sealing area of ​​an envelope. Background Technology

[0002] Release paper is a type of paper that prevents prepreg from sticking together and protects it from contamination. It is made of paper coated with an anti-sticking substance, and the models vary depending on the material, thickness, elongation, and whether it is single or double-sided. Release paper is also known as release paper, anti-stick paper, or silicone paper. It needs to be applied to the surface of envelopes during production. However, existing release paper application equipment has some shortcomings. In order to meet market needs, there is a need for a device for applying adhesive and release paper to the sealing area of ​​envelopes.

[0007] Preferably, the material discharge protection mechanism consists of a guide wheel, a foam protective pad, a mounting stud, and a guide frame. The inner wall of the discharge port is provided with a guide frame, and the surface of the guide frame is threadedly connected to a mounting stud.

[0013] 2. By incorporating a high-efficiency applicator, the pressure roller drives the moving frame and plate upwards, causing the plate to squeeze the elastic device. As the elastic device contracts, it applies force to the pressure roller, ensuring a more secure fit between the release paper and the envelope. Simultaneously, the elastic device prevents the pressure roller from obstructing the smooth passage of the release paper and envelope, resulting in more efficient and effective applicator application. This achieves the equipment's high-efficiency applicator function, enabling precise and efficient applicator application of the release paper to the envelope surface, thus improving the overall applicator performance.

Connecting brackets 113 are mounted on the surface of the mounting plates 117, and wheels 114 are mounted on the surface of the connecting brackets 113. The surfaces of wheel 114 and connecting frame 113 rotate in mutual engagement. The surface of wheel 114 contacts the surface of belt body 111. Envelope bodies 107 are placed on the surface of conveying assembly 108. The surfaces of envelope bodies 107 contact the surfaces of wheel 114 and drive wheel assembly 112, respectively. A paper guide frame 118 is installed on the surface of frame body 102. A guide wheel 116 is provided on the inner wall of the paper guide frame 118. The guide wheel 116 rotates in mutual engagement with the inner wall of the paper guide frame 118. The surface of the guide wheel 116 contacts the surface of release paper body 124. A rotating frame 121 is provided above the equipment frame 1. A covering wheel 120 is provided on the surface of the rotating frame 121. The covering wheel 120 rotates in mutual engagement with the surface of the rotating frame 121. The surface of the coating wheel 120 contacts the surface of the release paper body 124. A cylinder 109 is installed on the surface of the fixing frame 101. The cylinder 109 can be of the SC series. The input end of the cylinder 109 is electrically connected to the output end of the controller 11. The output end of the cylinder 109 rotates with the surface of the rotating frame 121. A laser positioning sensor 12 is installed on the surface of the rotating frame 121. The laser positioning sensor 12 can be of the LDM series. The output end of the laser positioning sensor 12 is electrically connected to the output end of the controller 11. A fixing plate 122 is installed on the surface of the top of the equipment frame 1. A tension spring 115 is installed on the surface of the fixing plate 122. The top end of the tension spring 115 is hung on the surface of the rotating frame 121.A cutting blade 119 is mounted on the surface of the rotating frame 121, and a discharge port 123 is provided on the surface at the bottom of the holding box 103.

[0021] Furthermore, such as Figure 2 and Figure 4 As shown, a material discharge protection mechanism 2 is provided on the inner wall of the discharge port 123 and the surface of the release paper body 124. The material discharge protection mechanism 2 consists of a guide wheel 21, a foam protective pad 22, a mounting stud 23, and a guide frame 24. The inner wall of the discharge port 123 is provided with a guide frame 24. The surface of the guide frame 24 is threadedly connected to the mounting stud 23. One end of the mounting stud 23 passes through the guide frame 24 and is threadedly fastened to the inner wall of the container 103. The inner wall of the guide frame 24 is provided with a guide wheel 21. The guide wheel 21 and the inner wall of the guide frame 24 rotate and cooperate with each other. The surface of the guide wheel 21 is covered with a foam protective pad 22. The surface of the foam protective pad 22 is in contact with the surface of the release paper body 124.

[0022] During implementation, the user installs the guide frame 24 on the inner wall of the discharge port 123 by tightening the mounting stud 23. When the release paper body 124 is being discharged, the release paper body 124 drives the guide wheel 21 to rotate on the inner wall of the guide frame 24. Under the action of the guide wheel 21, the guide frame 24 is guided. When the guide wheel 21 rotates, the guide wheel 21 drives the foam protective pad 22 to move to contact the surface of the release paper body 124. Under the action of the foam protective pad 22, the surface of the release paper body 124 can be protected, making it easier and smoother for the release paper body 124 to be discharged, so as to realize the function of the equipment in protecting the surface of the release paper body 124 during discharge.

[0023] Furthermore, such as Figure 2 and Figure 3 As shown, the inner wall of the fixing plate 122 and the surface of the release paper body 124 are provided with a high-efficiency bonding mechanism 3. The high-efficiency bonding mechanism 3 consists of a movable frame 31, a plate 32, an elastic device 33 and a pressure roller 34. The inner wall of the fixing plate 122 is provided with a plate 32. The movable frame 31 is installed on the surface of the bottom position of the plate 32. The inner side of the movable frame 31 is provided with a pressure roller 34. The pressure roller 34 and the inner wall of the movable frame 31 rotate and cooperate with each other. The surface of the pressure roller 34 is in contact with the surface of the release paper body 124. The inner wall of the fixing plate 122 is provided with an elastic device 33. The bottom end of the elastic device 33 is fixed to the surface of the top position of the plate 32.

[0024] During implementation, the pressure roller 34 drives the moving frame 31 and the plate 32 to move upward, causing the plate 32 to squeeze the elastic device 33. As the elastic device 33 contracts, it applies a certain force to the pressure roller 34. Under the action of the pressure roller 34, the release paper body 124 adheres more closely to the surface of the envelope body 107. At the same time, due to the setting of the elastic device 33, the pressure roller 34 does not affect the smooth passage of the release paper body 124 and the envelope body 107, making the release paper body 124 adhere to the surface of the envelope body 107 more efficiently and effectively, so as to realize the function of efficient application of the equipment.

[0025] Working principle: In use, first place the equipment frame 1 in the designated position. Under the action of the conveying component 108, the envelope body 107 is conveyed. When the drive wheel assembly 112 rotates, the drive wheel assembly 112 drives the belt body 111 to rotate on the surface of the pulley 110. At this time, the belt body 111 drives the wheel body 114 to rotate on the surface of the connecting frame 113. Under the combined action of the connecting frame 113 and the wheel body 114, the envelope body 107 is guided. The release paper body 124 wrapped around the surface of the paper roll 105 enters the interior of the holding box 103 and is discharged through the discharge port 123 on the surface of the holding box 103. Under the action of the guide wheel 116, the release paper body 124 is guided. When the envelope body 107 is being conveyed, it will be conveyed by the belt body 110. Glue is applied to the surface of the envelope body 107, allowing the release paper body 124 to adhere smoothly to the surface of the envelope body 107. Under the action of the applicating wheel 120, the release paper body 124 is precisely applicated to the surface of the envelope body 107. Subsequently, the position of the envelope body 107 is detected by the laser positioning sensor 12. When the envelope body 107 moves to the designated position, the laser positioning sensor 12 sends a signal to the controller 11. The controller 11 automatically controls the cylinder 109 to operate, driving the rotating frame 121 to move. At this time, the rotating frame 121 drives the cutting blade 119 to cut the surface of the release paper body 124, thereby allowing the release paper body 124 to be smoothly applicated to the surface of the envelope body 107. The specific composition and working principle of the conveying assembly 108 and the drive wheel assembly 112 are existing technologies and will not be described further here.

[0026] Subsequently, the user installs the guide frame 24 on the inner wall of the discharge port 123 by tightening the mounting stud 23. When the release paper body 124 is discharging, the release paper body 124 drives the guide wheel 21 to rotate on the inner wall of the guide frame 24. Under the action of the guide wheel 21, the guide frame 24 is guided. When the guide wheel 21 rotates, the guide wheel 21 drives the foam protective pad 22 to move to contact the surface of the release paper body 124. Under the action of the foam protective pad 22, the surface of the release paper body 124 can be protected, making it easier and smoother for the release paper body 124 to be discharged. This realizes the function of the equipment to protect the surface of the release paper body 124 during discharge, so that the release paper body 124 can be discharged more smoothly without jamming.

[0027] Subsequently, when the release paper body 124 is applied to the surface of the envelope body 107, the conveying assembly 108 moves the envelope body 107, causing the release paper body 124 applied to its surface to pass under the pressure roller 34. The pressure roller 34 drives the moving frame 31 and the plate 32 to move upward, causing the plate 32 to squeeze the elastic device 33. As the elastic device 33 contracts, it applies a certain force to the pressure roller 34. Under the action of the pressure roller 34, the release paper body 124 is applied to the envelope body 107. The release paper adheres more closely to the surface, and due to the setting of the elastic device 33, the pressure roller 34 will not affect the smooth passage of the release paper body 124 and the envelope body 107. This makes the release paper body 124 more efficient and effective when it is applied to the surface of the envelope body 107, thus realizing the efficient application function of the equipment. This allows the equipment to apply the release paper body 124 to the surface of the envelope body 107 efficiently and accurately, resulting in better performance when applying the release paper body 124, and ultimately completing the use of the 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.
