Description

Technical Field

[0001] This utility model belongs to the field of packaging box production technology, and in particular relates to a gluing device for packaging box production. Background Technology

[0002] According to the published patent CN216506991U, a gluing device for packaging box production is described. The output shaft of the adjusting motor passes through the side wall of the clamping plate and is fixedly connected to one end of a rotating screw. A driving block is threaded onto the rod wall of the rotating screw. A threaded hole is provided on the side wall of the driving block for threaded engagement with the rotating screw. The lower end of the driving block passes through a rectangular opening on the surface of the horizontal plate. A longitudinally arranged electric slide rail is fixedly connected to the lower end of the driving block. A support is fixedly connected to the lower end of the slider inside the electric slide rail. The support plate has a mounting plate fixedly connected to its lower end by multiple connecting columns. The mounting plate has through holes on its surface, and glue is fixedly inserted into these holes. The glue application head is moved left and right to a suitable position by rotating a screw and engaging a drive block. A telescopic cylinder pushes the glue application head down to a suitable glue application height. An electric slide rail moves the glue application head back and forth, achieving uniform glue application to the cardboard. This makes the glue application more precise, faster, and more uniform, ensuring glue application quality and efficiency. However, the following shortcomings still exist:

[0003] After the above equipment is completed, it simply applies glue evenly to the surface of the material by moving the glue applicator. However, since the material is in contact with the outside world before application and the surface of the material is easily contaminated with dust, the adhesiveness of the glue decreases due to the dust when applying the glue. Utility Model Content

[0004] The purpose of this utility model is to provide a glue coating device for packaging box production. Through the coating mechanism and storage mechanism, it solves the problem that the adhesiveness of the glue decreases due to dust on the surface of the material when it comes into contact with the outside world before coating.

A slider is rotatably connected to the outer wall of the several connecting rods on the side away from the triangular scraper. A second slider is rotatably connected to the outer wall of the slider. The second slider is slidably connected to the inner wall of the processing box. A pressure spring is fixedly connected to the outer wall of the second slider. A storage mechanism is provided on the outer wall of the processing box.

[0009] Furthermore, the storage mechanism includes a third pulley, the outer wall of which is fixedly connected to the outer wall of the positioning shaft, the outer wall of which is rotatably connected to the inner wall of the processing box, a second belt being drivenly connected to the inner wall of the third pulley, a fourth pulley being drivenly connected to the outer wall of the end of the second belt away from the third pulley, and the outer wall of the fourth pulley being rotatably connected to the outer wall of the support plate.

[0010] Furthermore, a crown gear is fixedly connected to the outer wall of the fourth pulley on the side away from the support plate. A gear meshes with the outer wall of the crown gear. A storage tank is rotatably connected to the outer wall of the gear. The outer wall of the storage tank is fixedly connected to the outer wall of the processing box. A feed pipe is fixedly connected to the outer wall of the storage tank. The outer wall of the feed pipe is fixedly connected to the inner wall of the support plate.

[0011] Furthermore, a second connecting shaft is fixedly connected to the bottom outer wall of the gear, the outer wall of the second connecting shaft is rotatably connected to the inner wall of the storage tank, and a connecting plate is rotatably connected to the outer wall of the end of the second connecting shaft away from the gear, the outer wall of the connecting plate being fixedly connected to the inner wall of the storage tank.

[0012] Furthermore, a plurality of second gears are rotatably connected to the bottom outer wall of the connecting plate, a heating rod is fixedly connected to the outer wall of the plurality of second gears, a third gear meshes with the outer wall of the second gear, and the outer wall of the third gear is fixedly connected to the outer wall of the second connecting shaft.

[0013] Furthermore, a positioning rod is fixedly connected to the bottom outer wall of the third gear, and a connecting block is rotatably connected to the outer wall of the positioning rod.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model incorporates a positioning shaft and brushes. The second pulley drives the positioning shaft to rotate, simultaneously causing multiple brushes on the surface of the positioning shaft 7 to sweep away dust from the material surface. This achieves the goal of rotating the positioning shaft via the second pulley, and continuously rotating the multiple brushes on the outer side of the positioning shaft, thus cleaning the surface of the object. This prevents the problem of reduced adhesive viscosity due to dust accumulation on the surface of the material before application, which is easily caused by dust contamination.

[0017] 2. This utility model incorporates a second gear and heating rods. Four heating rods are installed at the outermost end of the connecting plate. The heat dissipated by the heating rods ensures the liquid remains fluid. A second gear is located at the contact point between the heating rods and the connecting plate, and multiple second gears mesh with a third gear at the center of the connecting plate. Therefore, when the third gear rotates, it drives multiple second gears to rotate, thereby causing the four heating rods connected to it to rotate. This results in a slight flow of the liquid. The rotation of the third gear simultaneously drives the rotation of the second gears, and the heating rods dissipate heat while gently stirring the adhesive. This prevents problems such as the adhesive easily deforming and becoming non-flowable after long-term storage, and uneven application of adhesive when an object passes through the application area due to the adhesive's inability to flow.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 As shown, this utility model is a gluing device for packaging box production, including a base 1, a processing box 101 fixedly connected to the top outer wall of the base 1, the gluing part and the transportation part are wrapped by the processing box 101 to reduce external contact, and a support plate 102 fixedly connected to the top outer wall of the processing box 101.

[0029] The inner wall of the processing box 101 is provided with a coating mechanism 2, which includes a motor 201. The outer wall of the motor 201 is fixedly connected to the inner wall of the processing box 101. The output end of the motor 201 is fixedly connected to a connecting shaft 202 via a coupling. A conveyor belt 203 is driven to the outer wall of the connecting shaft 202. The motor 201 drives the connecting shaft 202 to rotate, simultaneously driving the conveyor belt 203. A pulley 204 is fixedly connected to the outer wall of the end of the connecting shaft 202 away from the motor 201. A belt 205 is driven to the inner wall of the pulley 204. A second pulley 205 is driven to the outer wall of the end of the belt 205 away from the pulley 204. 6. A belt 205 connects pulleys 204 and 206 simultaneously at both ends, causing them to rotate concurrently. A positioning shaft 207 is fixedly connected to the outer wall of the second pulley 206, and several brushes 208 are fixedly connected to its outer wall. The rotation of the second pulley 206 drives the positioning shaft 207 to rotate, causing the brushes 208 on the outer side of the positioning shaft 207 to contact the cardboard and conveyor belt, thus removing dust from the cardboard surface. A triangular scraper 209 is slidably connected to the outer wall of the conveyor belt 203 on the side away from the connecting shaft 202. The outer wall of the triangular scraper 209... A roller 210 is rotatably connected to the triangular scraper 209. The roller 210 at the front end of the triangular scraper 209 first contacts the object. When the object's thickness is sufficient, pushing the roller 210 pushes the rear triangular scraper 209 into contact with the object. A telescopic rod 216 is fixedly connected to the outer wall of the triangular scraper 209 away from the roller 210. The outer wall of the telescopic rod 216 is fixedly connected to the base 1. The movement of the triangular scraper 209 pulls the telescopic rod 216, thus limiting the movement range of the triangular scraper 209. Several connecting rods 211 are rotatably connected to the outer wall of the triangular scraper 209. A sliding contact is rotatably connected to the outer wall of the connecting rods 211 on the side away from the triangular scraper 209. Block 212, the outer wall of slider 212 is rotatably connected to a second slider 214, the second slider 214 is slidably connected to the inner wall of processing box 101, the outer wall of the second slider 214 is fixedly connected to a pressure spring 215, the movement of the triangular scraper 209 pushes the connecting rod 211 to move, while driving the slider 212 to move and push the support rod 213. When the support rod 213 rotates around the slider 212, it pushes the second slider 214 to move and squeezes the pressure spring 215 in the middle of the second slider 214. The elasticity of the pressure spring 215 increases the support of the support rod 213 for the triangular scraper 209. The outer wall of processing box 101 is provided with a storage mechanism 3.

[0030] The storage mechanism 3 includes a third pulley 301. The outer wall of the third pulley 301 is fixedly connected to the outer wall of the positioning shaft 207. The outer wall of the third pulley 301 is rotatably connected to the inner wall of the processing box 101. A second belt 302 is drivenly connected to the inner wall of the third pulley 301. A fourth pulley 303 is drivenly connected to the outer wall of the end of the second belt 302 away from the third pulley 301. By connecting the third pulley 301 and the fourth pulley 303 through the two ends of the second belt 302, the third pulley 301 and the fourth pulley 303 are driven to rotate simultaneously by the transmission of the second belt 302. The outer wall of the fourth pulley 303 is rotatably connected to the outer wall of the support plate 102. The fourth pulley 303 is located away from the support plate 102. A crown gear 304 is fixedly connected to one side of the outer wall. A gear 305 meshes with the outer wall of the crown gear 304. The crown gear 304 is driven to rotate by the fourth pulley 303. As the crown gear 304 meshes with the gear 305, the crown gear 304 pushes the gear 305 to rotate. A storage tank 306 is rotatably connected to the outer wall of the gear 305. The outer wall of the storage tank 306 is fixedly connected to the outer wall of the processing box 101. A feed pipe 307 is fixedly connected to the outer wall of the storage tank 306. The outer wall of the feed pipe 307 is fixedly connected to the inner wall of the support plate 102. The bottom of the feed pipe 307 is supported by the support plate 102, thereby preventing the material from shaking and spilling out when the material is poured into the storage tank 306 through the second connecting shaft 308.

[0031] A second connecting shaft 308 is fixedly connected to the bottom outer wall of gear 305. The outer wall of the second connecting shaft 308 is rotatably connected to the inner wall of storage tank 306. A connecting plate 309 is rotatably connected to the outer wall of the end of the second connecting shaft 308 away from gear 305. The outer wall of the connecting plate 309 is fixedly connected to the inner wall of storage tank 306. The rotation of gear 305 drives the second connecting shaft 308 to rotate, while the rotation range is limited by the connecting plate 309. Several second gears 310 are rotatably connected to the bottom outer wall of the connecting plate 309. A heating rod 312 is fixedly connected to the outer wall of several second gears 310. This heating rod 312 is a WDR type electric heating rod, which has good corrosion resistance and mechanical strength and can meet the heating requirements of various adhesives. The power range is relatively wide, commonly ranging from 100W to 3000W, which can be selected according to the size of the glue storage tank and the required heating speed. The outer wall of the second gear 310 meshes with the third gear 311. Through the meshing of the second gear 310 and the third gear 311, the third gear 311 drives the second gear 310 to rotate, thereby causing the heating rod 312 to rotate within the storage tank 306. The outer wall of the third gear 311 is fixedly connected to the outer wall of the second connecting shaft 308. A positioning rod 313 is fixedly connected to the bottom outer wall of the third gear 311. A connecting block 314 is rotatably connected to the outer wall of the positioning rod 313. The outer wall of the connecting block 314 is fixedly connected to the inner wall of the storage tank 306. Several discharge ports 315 are opened on the inner wall of the connecting block 314, allowing for... The rotation of the third gear 311 drives the positioning rod 313 to rotate inside the connecting block 314, and the glue flows out through multiple outlets 315 opened inside the connecting block 314. The outer wall of the end of the positioning rod 313 away from the third gear 311 is fixedly connected to a turbine blade 316. The rotation of the positioning rod 313 drives the turbine blade 316 to rotate, and the suction generated by the rotation of the turbine blade 316 is used to draw out the liquid. The outer wall of the turbine blade 316 is rotatably connected to the discharge pipe 317. The outer wall of the discharge pipe 317 is fixedly connected to the outer wall of the storage tank 306. The bottom outer wall of the discharge pipe 317 is fixedly connected to a nozzle 318. The liquid drawn out by the turbine blade 316 through the discharge pipe 317 is collected and sprayed out by the nozzle 318.

[0032] One specific application of this embodiment is:

[0033] When the equipment is needed, the required liquid is poured into the storage tank 306 through the feed pipe 307. The material is then placed on the side of the conveyor belt 203 near the positioning shaft 207. The motor 201 is then started, driving the connecting shaft 202 to rotate, which in turn drives the conveyor belt 203 to transport the material. During the rotation of the connecting shaft 202, the pulley 204 rotates. The two ends of the belt 205 connect the pulley 204 to the second pulley 206. Therefore, the belt 205 drives the second pulley 206 and pulley 204 to rotate simultaneously. The second pulley 206 then drives the positioning shaft 207 to rotate, simultaneously causing the multiple brushes 208 on the surface of the positioning shaft 207 to... Dust is swept away from the material surface. The rotation of the positioning shaft 207 drives the third pulley 301 to rotate simultaneously. At the same time, the two ends of the second belt 302 connect the third pulley 301 and the fourth pulley 303. Thus, the second belt 302 drives both the third pulley 301 and the fourth pulley 303 to rotate simultaneously. The fourth pulley 303 drives the crown gear 304 to rotate. Simultaneously, the crown gear 304 meshes with the gear 305, causing the crown gear 304 to push the gear 305 to rotate. The gear 305 then drives the second connecting shaft 308 to rotate, which in turn drives the third gear 311 to rotate. Meanwhile, the connecting plate 309 limits the rotation amplitude of the second connecting shaft 308 to prevent the third gear 311 from rotating improperly. Unexpected shaking occurs, and four heating rods 312 are installed at the outermost end of the connecting plate 309. The heat dissipated by the heating rods 312 ensures that the liquid remains flowing. A second gear 310 is provided at the contact point between the heating rods 312 and the connecting plate 309, and multiple second gears 310 mesh with a third gear 311 at the center of the connecting plate 309. Therefore, when the third gear 311 rotates, it drives multiple second gears 310 to rotate, thereby causing the four heating rods 312 connected to them to rotate, resulting in a slight flow of liquid. During the rotation of the third gear 311, the positioning rod 313 rotates, simultaneously driving the turbine blades 316 to rotate. The suction force generated by the rotation of the turbine blades 316 draws the liquid out. A connecting block 314 is provided at the connection between the turbine blade 316 and the positioning rod 313. The flow rate of the liquid is controlled by four discharge ports 315 opened inside the connecting block 314. Meanwhile, the rest of the turbine blade 316 is wrapped by the discharge pipe 317, thus preventing liquid leakage from the surface. A nozzle 318 is provided at the end of the discharge pipe 317. The nozzle 318 sprays the liquid in the discharge pipe 317 onto the surface of the material passing below. Subsequently, the material is contacted by the roller 210 at the outermost end of the triangular scraper 209 by the contact of the conveyor belt 203. The rotation of the roller 210 drives the triangular scraper 209 to contact the material surface. The two inclined sides of the triangular scraper 209 are used to evenly scrape the glue on the material surface to the surrounding area.During the movement of the triangular scraper 209, the telescopic rods 216 on both sides are pulled, thus limiting the movement range of the triangular scraper 209. Simultaneously, the movement of the triangular scraper 209 pushes the connecting rod 211 to move, while simultaneously pushing the slider 212 closer to the inner wall of the processing box 101 and causing it to slide upwards. This allows the slider 212 to push the support rod 213 to move. Since one end of the support rod 213 is connected to the second slider 214, and the second slider 214 is confined inside the processing box 101, it rotates around the slider 212 as the support rod 213 moves. This pushes the second sliders 214 on both sides closer together, compressing the pressure spring 215 in the middle. The elasticity of the pressure spring 215 increases the pressure of the connecting rod 211 on the triangular scraper 209, allowing the triangular scraper 209 to adhere more closely to the material surface. Subsequently, the material is moved to the other end of the device via the transmission of the conveyor belt 203.
