Description

Technical Field

[0001] This utility model belongs to the technical field of packaging material bonding equipment, specifically a gluing machine. Background Technology

[0002] With the rapid development of modern industry, EPE (Expanded Polyethylene) foam, as a lightweight, highly cushioning, and corrosion-resistant new environmentally friendly packaging material, has been widely used in the transportation and protection of high-value products such as electronic products, precision instruments, and handicrafts. Traditional EPE foam bonding processes mainly rely on hot-melt bonding technology, which involves melting and pressing a single layer of EPE foam at high temperatures using an aluminum heating plate, utilizing the material's own melting properties to achieve adhesion. However, this technology has significant drawbacks: high-temperature treatment easily damages the bubble structure on the surface of the EPE foam, reducing the material's cushioning performance; controlling the melting temperature and pressing time is difficult, easily leading to weak adhesion or excessive carbonization; and the process is only suitable for rough processing scenarios with low requirements for surface smoothness.

[0003] In existing technologies, some improved solutions employ adhesive-coating equipment, which uses adhesive to bond pearl cotton. However, existing adhesive-coating equipment typically includes a frame, an adhesive coating mechanism, a material handling mechanism, and two sets of feeding mechanisms. One set of feeding mechanisms is responsible for conveying the upper layer material, and the other is responsible for conveying the lower layer material. Furthermore, the two sets of feeding mechanisms are arranged perpendicularly to each other, resulting in a large footprint for the entire adhesive bonding equipment. In addition, both the adhesive coating mechanism and the material handling mechanism need to meet the requirements of multi-directional movement in the vertical and horizontal directions, which leads to a large number of drive components and higher equipment costs. Utility Model Content

[0004] To address the problems mentioned above, this utility model provides a gluing machine that uses only one feeding mechanism. The entire device has a compact structure and occupies a small area. Moreover, the gluing mechanism and the material handling mechanism only need to move up and down, resulting in fewer driving components and reduced equipment costs.

[0005] This utility model provides a gluing machine, including a frame and a feeding mechanism, a gluing mechanism, a picking mechanism, and a discharging conveying mechanism mounted on the frame. The feeding mechanism is located at one end of the frame and can move laterally along the frame. The gluing mechanism and the picking mechanism are both located above the feeding mechanism, and the discharging conveying mechanism is located below the feeding mechanism and is arranged laterally. The feeding mechanism includes a feeding platform and a feeding drive assembly connected to the feeding platform. The feeding drive assembly drives the feeding platform to move laterally, and the feeding platform holds the material to be glued. The gluing mechanism includes a fixed base fixed to the frame and located below the feeding platform, a lifting assembly mounted on the fixed base, and a gluing assembly mounted on the lifting end of the lifting assembly. The gluing assembly is located above the feeding platform.

[0008] Furthermore, the loading platform is provided with a first side positioning strip and a second side positioning strip that are perpendicular to each other, and the side edge of the material abuts and is positioned with the first side positioning strip and the second side positioning strip respectively.

[0009] Furthermore, the gluing assembly is mounted on a fixed base via a lifting assembly. The lifting assembly includes a first nut rotatably mounted on the fixed base, a first screw threaded to the first nut, and a first drive assembly for driving the first nut to rotate. The lower end of the first screw thread passes through the fixed base and extends downward, while the upper end of the first screw thread is connected to the gluing assembly.

[0010] Furthermore, there are multiple first nuts arranged circumferentially on the fixed base. The first drive assembly includes a second motor fixed on the fixed base and a fifth synchronous pulley connected to the second motor. A sixth synchronous pulley is fixedly fitted on each first nut, and a third synchronous belt is fitted on the fifth synchronous pulley and the multiple sixth synchronous pulleys.

[0011] Furthermore, at least one movable tensioning pulley is provided on the outer side of the third synchronous belt.

[0012] Furthermore, the lifting end of the lifting assembly has two spaced mounting plates fixed on it, and the glue applicator is installed on the lower end face of the mounting plates. The glue applicator includes a rotatable glue applicator roller, a second drive assembly that drives the glue applicator roller to rotate, and a glue storage tank set on the side of the glue applicator roller. A heating assembly is set below the glue storage tank. The heating assembly is used to heat the glue in the glue storage tank. The bottom of the glue storage tank has an opening facing the glue applicator roller. After the glue flows out from the opening, it adheres to the glue applicator roller. The glue applicator roller then coats the material with the glue.

[0013] Furthermore, a separation assembly is provided on the side of the glue-passing roller away from the glue storage tank. The separation assembly includes a plurality of arc-shaped separation elements spaced apart along the axial direction of the glue-passing roller.

[0025] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] The following is in conjunction with the appendix Figure 1 To be continued Figure 5 The present invention will be described in detail with specific embodiments.

[0027] Reference Figures 1-5This utility model provides a gluing machine, including a frame 1 and a feeding mechanism 2, a gluing mechanism 3, a picking mechanism 4, and a discharging conveying mechanism 5 disposed on the frame 1. The feeding mechanism 2 is disposed at one end of the frame 1 and can move laterally along the frame 1. The gluing mechanism 3 and the picking mechanism 4 are both located above the feeding mechanism 2, and the discharging conveying mechanism 5 is located below the feeding mechanism 2 and is arranged laterally. The feeding mechanism 2 is used to transport upper and lower materials and reciprocate between the gluing mechanism 3 and the picking mechanism 4. The gluing mechanism 3 is used to apply glue to the upper surface of the lower material. The picking mechanism 4 is used to pick up the upper material and bond the upper material to the lower material. The discharging conveying mechanism 5 is used to convey the bonded material from the end away from the feeding mechanism 2. Specifically, the discharging conveying mechanism 5 can be a conveyor belt, but it is not limited to this. This application does not limit the specific structure of the discharging conveying mechanism 5, as long as it can perform the function of conveying materials. It should be noted that both the lower and upper materials are packaging materials. For the sake of clarity, the lower and upper materials are referred to as "lower material" and "upper material" respectively.

[0028] The feeding mechanism 2 includes a feeding platform 21 and a feeding drive component 22 connected to the feeding platform 21. The feeding drive component 22 drives the feeding platform 21 to move laterally. Upper materials and lower materials are stacked on the feeding platform 21. This application does not limit the specific structure of the feeding drive component 22, as long as it can drive the feeding platform 21 to move laterally. For example, the feeding drive component 22 can be a gear and rack drive component, a screw drive component, a conveyor belt drive component, etc., but is not limited to these.

[0029] In a specific embodiment, the feeding drive assembly 22 includes a first motor 221 fixed on the frame 1. The first motor 221 is located below the feeding platform 21. A first synchronous pulley 222 is connected to the output shaft of the first motor 221. A second synchronous pulley 223 cooperates with the first synchronous pulley 222. A first synchronous belt 224 is fitted between the first synchronous pulley 222 and the second synchronous pulley 223. A drive shaft 225 is connected through the second synchronous pulley 223. A third synchronous pulley 226 is connected to both ends of the drive shaft 225. A fourth synchronous pulley 227 cooperates with the third synchronous pulley 226. A second synchronous belt 228 is fitted between the third synchronous pulley 226 and the fourth synchronous pulley 227. The lower surface of the feeding platform 21 is fixed to the second synchronous belt 228 by a connector 229. The frame 1 is also provided with a guide rail 23 located below the feeding platform 21 and extending laterally. A guide slider 24 that cooperates with the guide rail 23 is fixed to the lower surface of the feeding platform 21. The first motor 221 drives the first synchronous pulley 222 to rotate. The first synchronous pulley 222 drives the second synchronous pulley 223 to rotate via the first synchronous belt 224. The second synchronous pulley 223 drives the third synchronous pulley 226 at both ends to rotate via the transmission shaft 225. The third synchronous pulley 226 drives the fourth synchronous pulley 227 to rotate via the second synchronous belt 228. The second synchronous belt 228 drives the loading platform 21 to move laterally via the connector 229. At the same time, the loading platform 21 can move more stably back and forth through the cooperation of the guide rail 23 and the guide slider 24.

[0030] Preferably, the feeding platform 21 is provided with a first side positioning strip 25 and a second side positioning strip 26 that are perpendicular to each other, and the side of the material being fed abuts and is positioned against the first side positioning strip 25 and the second side positioning strip 26 respectively.

[0031] The gluing mechanism 3 includes a fixed base 31 fixed to the frame 1 and located below the loading platform 21, a lifting assembly 32 disposed on the fixed base 31, and a gluing assembly 33 installed on the lifting end of the lifting assembly 32. The gluing assembly 33 is located above the loading platform 21. The gluing assembly 33 is mounted on the fixed base 31 via the lifting assembly 32. The lifting assembly 32 includes a first nut 321 rotatably disposed on the fixed base 31, a first screw 322 screwed to the first nut 321, and a first drive assembly 35 for driving the first nut 321 to rotate. The lower end of the first screw 322 passes through the fixed base 31 and extends downward, and the upper end of the first screw 322 is connected to the gluing assembly 33. It can be understood that the function of the first drive assembly 35 in this application is to drive the first nut 321 to rotate. Therefore, the specific structure of the first drive assembly 35 is not limited, as long as it can achieve the rotation of the first nut 321, it falls within the protection scope of this application. In a specific embodiment, there are multiple first nuts 321 arranged circumferentially on the fixed base 31. The first drive assembly 35 includes a second motor 351 fixed on the fixed base 31 and a fifth synchronous pulley 352 connected to the second motor 351. Each first nut 321 is fixedly fitted with a sixth synchronous pulley 353. A third synchronous belt 354 is fitted on the fifth synchronous pulley 352 and the multiple sixth synchronous pulleys 353. The second motor 351 drives the fifth synchronous pulley 352 to rotate. The fifth synchronous pulley 352 drives the sixth synchronous pulley 353 to rotate through the third synchronous belt 354. The sixth synchronous pulley 353 drives the first nut 321 to rotate. The first nut 321 then drives the first screw 322 to rise and fall.

[0032] Preferably, at least one movable tensioning pulley 355 is also provided on the outer side of the third synchronous belt 354. It is understood that the tension of the third synchronous belt 354 will decrease during long-term use, causing the third synchronous belt 354 to loosen. By providing a movable tensioning pulley 355, this application can adjust the tension of the third synchronous belt 354 at any time according to the usage of the third synchronous belt 354, ensuring the synchronous rotation of all first nuts 321.

[0033] The lifting assembly 32 has two spaced-apart mounting plates 323 fixed to its lifting end. The gluing assembly 33 is mounted on the lower end face of the mounting plates 323. The gluing assembly 33 includes a rotatably mounted gluing roller 331, a second drive assembly 332 that drives the gluing roller 331 to rotate, and a glue storage tank 333 disposed on the side of the gluing roller 331. It can be understood that the function of the second drive assembly 332 in this application is to drive the gluing roller 331 to rotate. Therefore, the specific structure of the second drive assembly 332 is not limited, as long as it can realize the rotation of the gluing roller 331, it falls within the protection scope of this application. The opening end of the glue storage tank 333 faces upward. A heating assembly is disposed below the glue storage tank 333. The heating assembly is used to heat the glue in the glue storage tank 333. The heating assembly can be electric heating or electromagnetic heating, etc. Therefore, the specific structure of the heating assembly is not limited. The bottom of the glue storage tank 333 has an opening facing the glue transfer roller 331. After the glue flows out from the opening, it adheres to the glue transfer roller 331 and is then applied to the material below by the glue transfer roller 331. A separation component 334 is provided on the side of the glue transfer roller 331 away from the glue storage tank 333. The separation component 334 includes a plurality of arc-shaped separation members 3341 spaced apart along the axial direction of the glue transfer roller 331. The arc-shaped separation members 3341 are used to prevent the material below from sticking to the glue transfer roller 331 and lifting off the loading platform 21.

[0034] The material handling mechanism 4 includes a fixed plate 41 fixedly connected to the frame 1 and a material handling component 42 that is vertically movable on the fixed plate 41. The material handling component 42 includes a lifting plate 421, a material handling part 422 disposed at the lower end of the lifting plate 421, and a third drive component 423 that drives the lifting plate 421 to move up and down. The third drive component 423 includes a third motor 4231 fixedly on the upper end of the lifting plate 421, a drive wheel 4232 mounted on the output shaft of the third motor 4231, a driven wheel 4233 cooperating with the drive wheel 4232, a belt 4234 mounted on the drive wheel 4232 and the driven wheel 4233, and a second screw 4235 connected to the driven wheel 4233. A second nut 4236 is fixed on the side of the fixed plate 41 opposite to the lifting plate 421, and the second nut 4236 is threadedly connected to the second screw 4235. The output shaft of the third motor 4231 rotates, driving the drive wheel 4232 to rotate. The drive wheel 4232 drives the driven wheel 4233 to rotate via the belt 4234. The driven wheel 4233 drives the second screw 4235 to rotate. The second screw 4235 cooperates with the second nut 4236 to realize the up and down movement of the lifting plate 421. The lifting plate 421 drives the picking component 422 to move up and down. The picking component 422 in this application can be a picking suction cup or a picking needle plate, but is not limited to these.

[0035] The working principle of the adhesive bonding machine provided by this utility model is as follows: The operator stacks the upper and lower materials on the loading platform 21. The loading drive component 22 drives the loading platform 21 to move laterally. The loading platform 21 first moves to the bottom of the picking mechanism 4. The picking mechanism 4 moves downward to pick up the upper material. Then the loading platform 21 drives the lower material to the bottom of the adhesive bonding mechanism 3. The adhesive bonding mechanism 3 moves downward and applies adhesive to the upper surface of the lower material. After applying adhesive, the loading platform 21 drives the lower material to the bottom of the picking mechanism 4 again. The picking mechanism 4 drives the upper material to move downward and adhesives the upper and lower materials together. Then the picking mechanism 4 picks up the adhesive material. The loading platform 21 moves to the initial position to perform the next operation. Then the picking mechanism 4 releases the adhesive material so that the adhesive material falls onto the discharge conveying mechanism 5 below. The discharge conveying mechanism 5 conveys the adhesive material from the end away from the loading platform 21. This utility model uses only one set of feeding mechanism 2, the whole equipment has a compact structure and a small footprint, and the gluing mechanism 3 and the material picking mechanism 4 only need to move up and down, with fewer driving parts, which reduces the cost of the equipment.

However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention.
