Description

Technical Field

[0001] This utility model belongs to the field of bag making machine technology, and in particular relates to an adhesive applicator for a bag making machine. Background Technology

[0002] In the production and application of plastic bags, in order to meet users' needs for convenient sealing, attaching adhesive strips to the bag sealing area has become an important process. These adhesive strips are usually double-sided, with one side attached to the bag sealing area and the other side covered with release paper. Users only need to tear off the release paper to complete the sealing. They are widely used in food packaging, daily necessities storage, express packaging and other scenarios.

[0003] In the existing adhesive strip process, the pulley guide structure is not specifically designed for the front and back sides of the adhesive strip. When the adhesive strip is transported, if the adhesive side contacts the pulley surface, the viscous components in the adhesive are easily stuck to the pulley, which can easily cause the adhesive strip's own adhesion to decrease due to adhesive loss. If a guide method is adopted in which the back side of the adhesive strip contacts the pulley, when the tension is insufficient due to factors such as uneven roll tightness or fluctuations in feeding speed during the transport of the adhesive strip, the adhesive strip is very likely to detach from the pulley track. Derailment of the adhesive strip will not only interrupt the bonding process, but may also cause malfunctions such as the adhesive strip wrapping around equipment parts or tearing. Therefore, a bag making machine adhesive bonding device is needed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a bag making machine adhesive applicator to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A bag-making machine adhesive applicator includes a workbench, a protective box connected to the top of one side of the workbench, an adhesive applicator assembly connected inside the protective box, a guide roller rotatably connected to the inner top of the workbench, and a plastic bag slidably connected to the top of the guide roller.

[0007] The adhesive application assembly includes a motor, the output end of which is connected to a drive wheel. There are two drive wheels, and a belt connects the two drive wheels. A connecting shaft is welded to the inner side of one of the drive wheels, and a connecting block is welded to the outer side of the connecting shaft. An adhesive roller is movably connected to the outer side of the connecting shaft. A hollow rod is welded to the inside of the other drive wheel, and a pressure roller is welded to the outer side of the hollow rod. A vacuum pump is connected through one end of the hollow rod.

[0008] In a further technical solution, a fixing plate is connected to one side of the protective box, slots are provided on both sides of the rubber roller, a bearing plate is rotatably connected inside the fixing plate, a buckle is provided on one side of both the connecting block and the bearing plate, and one end of the connecting shaft is connected to the bearing plate.

[0009] In a further technical solution, the buckle is connected to the slot, and a fixing bolt is connected between the fixing plate and the protective box, with the number of fixing bolts being four.

[0010] A further technical solution is provided, wherein the protective box is internally connected to a fixed pulley, the outer side of the rubber roller is covered with a rubber strip, the top of the rubber strip is slidably connected to the fixed pulley and the pressure roller, the bottom of the rubber strip is connected to the sealing end of the plastic bag, a support plate is connected to the top inner side of the workbench, and the bottom of the plastic bag is movably connected to the top of the support plate.

[0011] In a further technical solution, the outer side of the pressure roller is hollowed out, and the hollowed-out pressure roller is interconnected with the hollow rod and the vacuum pump.

[0012] In a further technical solution, a connector is connected to one side of the worktable, one end of the hollow rod is rotatably connected to the inner side of the connector, the outer side of the connector is connected to one side of the vacuum pump, and a controller is connected to the other side of the worktable.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention utilizes a fixed pulley to contact the non-adhesive surface of the adhesive strip, while the pressure roller features a hollow design and is connected to a vacuum pump. Negative pressure adsorption force stably constrains the adhesive strip to the outside of the pressure roller, preventing direct contact between the adhesive surface of the adhesive strip and the guide components. This prevents adhesive loss due to adhesion to the pulley, ensuring the adhesive strip maintains its initial tack and effectively reducing delamination and detachment during later use. The vacuum pump and hollow pressure roller design allow for adhesive strip adsorption, preventing the adhesive strip from detaching from the track even with uneven roll tension or fluctuating feeding speed.

[0015] In this invention, the slots on both sides of the rubber roller cooperate with the buckles on the fixed plate to achieve precise positioning of the rubber strip transmission path. The fixed plate and the protective box are connected by fixing bolts, and the rubber roller and the connecting shaft are assembled with a snap-fit. When it is necessary to replace rubber strips of different specifications, the relevant parts can be quickly disassembled and adjusted, which greatly improves work efficiency. In addition, the controller on one side of the workbench can adjust the motor speed and vacuum pump negative pressure in real time, adapting to various plastic bags of different thicknesses, greatly expanding the applicability of the device.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] like Figures 1-6 As shown, this utility model embodiment provides a bag making machine adhesive applicator, including a workbench 1, a protective box 2 connected to the top of one side of the workbench 1, an adhesive applicator 3 connected inside the protective box 2, a guide roller 4 rotatably connected to the inner top of the workbench 1, and a plastic bag 5 slidably connected to the top of the guide roller 4.

[0027] The adhesive application assembly 3 includes a motor 301. The output end of the motor 301 is connected to a transmission wheel 302. There are two transmission wheels 302, and a belt 303 connects the two transmission wheels 302. A connecting shaft 304 is welded to the inner side of one of the transmission wheels 302, and a connecting block 305 is welded to the outer side of the connecting shaft 304. An adhesive roller 306 is movably connected to the outer side of the connecting shaft 304. A hollow rod is welded to the inside of the other transmission wheel 302, and a pressure roller 307 is welded to the outer side of the hollow rod. A vacuum pump 308 is connected through one end of the hollow rod.

[0028] In this embodiment, the controller 8 starts the motor 301, which drives the connecting shaft 304 and the hollow rod to rotate synchronously through the transmission wheel 302 and the belt 303, releasing the adhesive strip 9. At the same time, the pressure roller 307 attaches the adhesive strip 9 to the top of the plastic bag 5. Simultaneously, the vacuum pump 308 is started, which delivers negative pressure into the hollow pressure roller 307 through the hollow rod. The pressure difference is used to tightly adsorb the adhesive strip 9 onto the surface of the pressure roller 307. With the guidance of the fixed pulley 14, the non-adhesive surface of the adhesive strip comes into contact with the guiding component, which prevents the adhesive strip 9 from derailing and avoids glue loss caused by adhesion of the adhesive surface.

[0029] like Figures 2-6 As shown, specifically, a fixing plate 6 is connected to one side of the protective box 2, and slots 10 are opened on both sides of the rubber roller 306. A bearing plate is rotatably connected inside the fixing plate 6. A buckle 14 is provided on one side of both the connecting block 305 and the bearing plate. One end of the connecting shaft 304 is connected to the bearing plate.

[0030] The buckle 14 is connected to the slot 10, and the fixing plate 6 is connected to the protective box 2 by fixing bolts 7, and there are four fixing bolts 7.

[0031] The protective box 2 is internally connected to a fixed pulley 13, and the outer side of the rubber roller 306 is covered with a rubber strip 9. The top of the rubber strip 9 is slidably connected to the fixed pulley 13 and the pressure roller 307. The bottom of the rubber strip 9 is connected to the sealing end of the plastic bag 5. The top inner side of the workbench 1 is connected to a support plate 11, and the bottom of the plastic bag 5 is movably connected to the top of the support plate 11.

[0032] The outer side of the pressure roller 307 is hollow, and the hollow pressure roller 307 is connected to the hollow rod and the vacuum pump 308.

[0033] A connector 12 is connected to one side of the workbench 1. One end of the hollow rod is rotatably connected to the inner side of the connector 12. The outer side of the connector 12 is connected to one side of the vacuum pump 308. A controller 8 is connected to the other side of the workbench 1.

[0034] In this embodiment, the operator adjusts the position of the fixing plate 6 according to the size of the adhesive strip 9 using the fixing bolts 7, so that the slots 10 on both sides of the adhesive roller 306 precisely engage with the buckles 14, and puts the adhesive roller 9 on the outside of the connecting shaft 304. One end of the adhesive strip 9 is pulled around the fixed pulley 13 and the pressure roller 307 in sequence, so that the non-adhesive surface of the adhesive strip 9 contacts the fixed pulley 13 and the adhesive surface faces downward. The speed of the motor 301 and the negative pressure value of the vacuum pump 308 are set by the controller 8 to facilitate the user's operation. When the sealing end of the plastic bag 5 moves directly under the pressure roller 307, the pressure roller 307 precisely presses the adhesive surface of the adhesive strip onto the surface of the plastic bag 5, completing the attachment action.

[0035] The working principle of this utility model is as follows: First, the operator adjusts the position of the fixing plate 6 according to the size of the rubber strip 9 using the fixing bolts 7, so that the slots 10 on both sides of the rubber roller 306 precisely engage with the buckles 14. The rubber roller 9 is then placed on the outside of the connecting shaft 304, and one end of the rubber strip 9 is pulled around the fixed pulley 13 and the pressure roller 307 in sequence, so that the non-adhesive surface of the rubber strip 9 contacts the fixed pulley 13, and the adhesive surface faces downward. Then, the motor 301 is started by the controller 8, and the motor 301 is connected to the belt 30 through the transmission wheel 302. 3. Drive the connecting shaft 304 and the hollow rod to rotate synchronously, releasing the adhesive strip 9. At the same time, start the vacuum pump 308. The vacuum pump 308 delivers negative pressure to the hollow pressure roller 307 through the hollow rod. The pressure difference is used to tightly adsorb the adhesive strip 9 onto the surface of the pressure roller 307. With the guiding action of the fixed pulley 14, the non-adhesive surface of the adhesive strip comes into contact with the guiding component. Finally, when the sealing end of the plastic bag 5 moves directly under the pressure roller 307, the pressure roller 307 precisely presses the adhesive surface of the adhesive strip onto the surface of the plastic bag 5, completing the attachment action.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
