Description

Technical Field

[0001] This utility model relates to the field of cardboard box processing technology, and in particular to a high-efficiency cardboard box gluing machine. Background Technology

[0002] In the carton packaging industry, the carton gluing machine is a key piece of equipment that plays a decisive role in the production efficiency and quality of cartons. With the continuous growth of demand for cartons from various industries, the performance requirements for carton gluing machines are also increasing. At present, there are many types of carton gluing machines on the market, but some problems still need to be solved in actual use.

[0003] On the one hand, the glue supply and dispensing systems of traditional gluing machines are not designed reasonably. Some gluing machines use a simple glue application method, and the glue in the glue box is not replenished in time, resulting in insufficient glue supply during continuous operation, which affects gluing efficiency. At the same time, the glue dispensing device cannot control the amount of glue dispensed and the application position, which easily leads to glue waste or uneven application, resulting in weak carton adhesion and an increased defect rate. On the other hand, existing gluing machines have defects in carton positioning and operational stability. During the gluing process, the carton is prone to displacement, causing the glue application position to deviate and affecting the adhesion quality of the carton. Therefore, it is necessary to design a high-efficiency gluing machine to solve the above problems. Utility Model Content

[0004] The main objective of this invention is to provide a high-efficiency carton gluing machine that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A high-efficiency carton gluing machine includes a workbench, a support plate fixedly connected to the upper left of the conveying workbench, a pushing device fixedly connected to the upper end of the support plate, a side plate fixedly connected to the upper right of the support plate, an adhesive applicator fixedly connected to the upper middle of the side plate, a concave bearing plate placed in the upper middle of the workbench, a control panel provided at the front end of the support plate, a baffle fixedly connected between the lower part of the front wall and the lower part of the rear wall of the support plate, a sliding groove opened between the middle of the front wall and the rear wall of the support plate, and a connecting plate fixedly connected between the middle of the front wall and the rear wall of the support plate.

[0007] Preferably, the pushing device includes a first electric push rod, the output end of which passes through the connecting plate and is fixedly connected to a glue box. A slider is fixedly connected to both the front and rear ends of the glue box. A glue-adhesive groove is formed on the upper right side of the glue box. Guide rods are fixedly connected to both the front and rear left ends of the glue box. Two conveying hoses are fixedly connected to the middle left end of the glue box. A glue tank is fixedly connected to the other end of each conveying hose. A lid is provided at the front upper end of the glue tank. Solenoid valves are provided on the outer surface of each conveying hose. The first electric push rod is fixedly connected to the middle left end of the connecting plate.

[0008] Preferably, the adhesive applicator includes a second electric push rod, the output end of which passes through a support plate and is fixedly connected to a lifting plate. The lower end of the lifting plate has a slot, and brackets are fixedly connected to both the front and rear upper ends of the lifting plate. A sleeve rod is inserted and fixedly connected to the front upper end of the bracket, and a rubber pressure block is fixedly connected to the lower end of each sleeve rod. A bolt is threadedly connected to the rear upper end of the lifting plate, and a retaining strip is threaded onto the lifting plate via the bolt. An adhesive plate is fixedly connected to the lower end of the retaining strip, and the second electric push rod is fixedly connected to the upper end of the side plate.

[0009] Preferably, the sliders are slidably connected in the grooves, and the glue box is connected to the inside of the glue tank through two delivery hoses.

[0010] Preferably, the two guide rods are respectively inserted into and movably installed with the connecting plate, and the two guide rods are symmetrically distributed front and back.

[0011] Preferably, the position and size of the card strip are adapted to the position and size of the card slot.

[0012] Preferably, the position and size of the adhesive plate are adapted to the position and size of the adhesive groove, and the rubber blocks are all of the following structure: narrow at the top and wide at the bottom.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In this utility model, the pushing stroke of the glue box is precisely controlled by the first electric push rod. Combined with the smooth sliding of the slider and the chute and the stable guidance of the guide rod, the linear movement of the glue box is ensured, so that the glue-adhesive trough is accurately aligned with the glue-applying device. At the same time, the double delivery hoses are equipped with solenoid valves, which can control the glue tank to replenish glue to the glue box in real time according to the movement status of the glue box, so as to realize the flow control and timely supply of glue, avoid the situation of insufficient glue supply during continuous operation, and significantly improve the efficiency of gluing boxes. In addition, the glue-applying plate and the glue-applying trough are matched in position and size, which can control the amount of glue applied, avoid glue waste or uneven application, and effectively reduce the defect rate of poorly glued cartons.

[0015] 2. In this utility model, the lifting plate, through the tight fit of the slot and the strip and the fixing with bolts, ensures the precise positioning of the adhesive plate and the accurate and unbiased position when applying glue. At the same time, the sleeve rod on the bracket drives the rubber pressure block with a narrow upper and wide lower structure to press down synchronously. Utilizing its progressive clamping force, it can effectively press the edges of the carton to prevent displacement and avoid damage to the carton body. This solves the problem of displacement of the carton during the gluing process, which leads to deviation in the glue application position. In addition, the cooperation between the slider and the groove in the pushing device, the guiding effect of the guide rod, and the coordinated work of various components ensure the smoothness of the pushing and gluing actions, further guaranteeing the gluing quality of the carton.

[0025] Please see Figure 1-5 This utility model provides a technical solution:

[0026] A high-efficiency carton gluing machine includes a workbench 1. A support plate 2 is fixedly connected to the upper left part of the conveying workbench 1. A pushing device 3 is fixedly connected to the upper end of the support plate 2. A side plate 5 is fixedly connected to the upper right part of the support plate 2. An adhesive applicator 4 is fixedly connected to the upper middle part of the side plate 5. A concave bearing plate 7 is placed in the upper middle part of the workbench 1. A control panel 6 is provided at the front end of the support plate 2. A baffle 8 is fixedly connected between the lower part of the front wall and the lower part of the rear wall of the support plate 2. A sliding groove 9 is opened between the middle part of the front wall and the rear wall of the support plate 2. A connecting plate 10 is fixedly connected between the middle part of the front wall and the rear wall of the support plate 2.

[0027] In this embodiment, the feeding device 3 includes a first electric push rod 31. The output end of the first electric push rod 31 passes through the connecting plate 10 and is fixedly connected to a glue box 32. The front and rear ends of the glue box 32 are fixedly connected to sliders 33. The upper right part of the glue box 32 has an adhesive groove 39. The front and rear left ends of the glue box 32 are fixedly connected to guide rods 34. The middle left end of the glue box 32 is fixedly connected to two conveying hoses 35. The other ends of the conveying hoses 35 are fixedly connected to a glue tank 37. The front upper end of the glue tank 37 is provided with a box cover 38. The outer surface of the conveying hoses 35 is provided with solenoid valves 36. The first electric push rod 31 is fixedly connected to the middle left end of the connecting plate 10. The sliders 33 are slidably connected in the grooves 9. The glue box 32 communicates with the inside of the glue tank 37 through the two conveying hoses 35. The two guide rods 34 are inserted and movably installed with the connecting plate 10, and the two guide rods 34 are symmetrically distributed front and back.

[0028] The working principle of the pushing device 3 is as follows: After the first electric push rod 31 is started, its output end pushes the glue box 32 to move smoothly along the slide groove 9 through the slider 33. At the same time, the guide rod 34 passes through the connecting plate 10 to provide stable guidance and ensure that the glue box 32 moves linearly. When the glue box 32 moves, the solenoid valve 36 controls the delivery hose 35 to replenish glue from the glue tank 37 to the glue box 32. The glue is delivered to the adhesive board 49 through the adhesive groove 39. The box cover 38 facilitates the filling and maintenance of the glue tank 37. The first electric push rod 31 accurately controls the pushing stroke of the glue box 32. The slider 33 and the slide groove 9 cooperate to ensure smooth operation. The guide rod 34 enhances the structural stability. The double delivery hose 35 improves the glue supply efficiency. The solenoid valve 36 realizes flow control and significantly improves the working efficiency of the gluing machine.

[0029] In this embodiment, the adhesive applicator 4 includes a second electric push rod 41. The output end of the second electric push rod 41 passes through the support plate 2 and is fixedly connected to a lifting plate 42. The lower end of the lifting plate 42 has a slot 47. The upper front and upper rear of the lifting plate 42 are both fixedly connected to a bracket 43. The upper front of the bracket 43 is inserted and fixedly connected to a sleeve rod 44. The lower end of the sleeve rod 44 is fixedly connected to a rubber pressure block 45. The upper rear of the lifting plate 42 is threadedly connected to a bolt 46. The lifting plate 42 is threadedly installed with a locking strip 48 through the bolt 46. The lower end of the locking strip 48 is fixedly connected to an adhesive plate 49. The second electric push rod 41 is fixedly connected to the upper end of the side plate 5. The position and size of the locking strip 48 are adapted to the position and size of the slot 47. The position and size of the adhesive plate 49 are adapted to the position and size of the adhesive groove 39. The rubber pressure blocks 45 are all narrow at the top and wide at the bottom.

[0030] Through the above scheme: after the second electric push rod 41 is started, it drives the lifting plate 42 to move vertically, which drives the adhesive plate 49 fixed at the lower end of the clip 48 to be precisely pressed into the adhesive groove 39 of the glue box 32 to complete the glue application. The clip 48 is detachably positioned with the clip groove 47 of the lifting plate 42 by bolts 46. When the adhesive plate 49 applies glue to the carton, the sleeve rod 44 on the bracket 43 simultaneously drives the rubber pressure block 45 with a narrow upper and wide lower structure to press the edge of the carton to prevent displacement. The second electric push rod 41 provides stable power output. The cooperation between the clip groove 47 and the clip 48 ensures the positioning of the adhesive plate 49. The detachable design facilitates maintenance and replacement. The special structure of the rubber pressure block 45 forms a progressive clamping force when pressure is applied, which can effectively fix the carton and avoid damage to the carton. The whole device realizes high-efficiency glue application and significantly improves the quality of carton gluing.

[0031] It should be noted that this utility model is a high-efficiency carton gluing machine. The device is connected to an external power supply. The operator starts the equipment through the control panel 6. First, the carton to be glued is placed on the concave support plate 7. The second electric push rod 41 of the glue applicator 4 pushes the lifting plate 42 down, so that the glue plate 49 is immersed in the glue groove 39 on the upper right side of the glue box 32 of the pusher device 3 to pick up glue. At this time, the solenoid valve 36 controls the delivery hose 35 to replenish glue from the glue tank 37 to the glue box 32. After the glue application is completed, the first electric push rod 31 drives the glue box 32 to retract to the left. The glue box 32 is then moved by the slider. 33 slides along the slide groove 9, while the guide rod 34 moves smoothly under the guidance of the connecting plate 10. Then, the second electric push rod 41 pushes the lifting plate 42 down again, so that the adhesive plate 49 applies glue to the edge of the cardboard. At this time, the lower end of the lifting plate 42 is tightly engaged with the slot 47 by the clip 48 fixed by the bolt 46, ensuring that the adhesive plate 49 is accurately positioned. The sleeve rod 44 at the upper end of the bracket 43 drives the rubber pressure block 45 to press down synchronously, using its narrow upper and wide lower structure to press the cardboard to prevent movement. After the bonding is completed, all devices are reset, and the baffle 8 prevents the material from shifting, realizing efficient and continuous box gluing operation.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
