Description

Technical Field

[0001] This utility model relates to the field of production control technology, specifically to a double-plate pressing device for protruding models. Background Technology

[0002] In the packaging industry, when factories produce corresponding packaging products, they need to press a plate with a protrusion onto a flat cardboard. Since the flat cardboard has been glued by a dispensing machine in the previous process, the bonding between the protrusion plate and the flat cardboard can be achieved during the pressing process.

[0003] In existing technologies, the bonding between raised plates and flat cardboard is usually done manually, which wastes a lot of manpower and resources and reduces production efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention aims to provide a double-plate pressing device for raised models. By employing this solution, the raised plate and the flat cardboard are bonded together through the upward adsorption and downward pressing of the lifting control unit, thereby improving production efficiency.

[0005] This utility model is achieved through the following technical solution: A double-plate pressing device for protruding models, comprising: A lifting control unit is fixed above the conveyor belt with its output end facing downwards; A concave block, the concave block having a groove in the middle, is fixed to the output end of the lifting control unit, and the opening of the groove faces downward; A pressure plate frame is fixed to the lower side of the concave block, and the central channel of the pressure plate frame is connected to the groove; the lower surface of the pressure plate frame is provided with a plurality of negative pressure suction ports in the circumferential direction.

[0006] Compared to existing technologies where bonding between raised plates and flat cardboard is usually done manually, resulting in significant waste of manpower and resources and reduced production efficiency, this invention provides a double-plate pressing device for raised models. This solution achieves bonding between raised plates and flat cardboard through the upward adsorption and downward pressing of the lifting control unit, thereby improving production efficiency. The specific solution includes a lifting control unit fixed above the conveyor belt. The lifting control unit is preferably a lifting cylinder with its output end facing downwards. A recessed block with a groove is fixed at the output end of the lifting control unit and is inverted, with the groove opening facing downwards. A pressure plate frame is provided below the recessed block. The pressure plate frame is frame-shaped with a channel in its middle, the channel's size matching the groove and communicating with it. The conveyor belt alternately transports the raised plate and the flat cardboard. When the raised plate moves below the pressure plate frame, the conveyor belt stops briefly, driving the pressure plate frame downwards. At this time, the raised portion of the raised plate can enter the groove to avoid obstruction. The negative pressure suction port on the periphery of the pressure plate frame can suck up the raised plate and then move upwards, lifting it. The conveyor belt continues to drive. When the glued flat cardboard moves below, the conveyor belt stops again, driving the pressure plate frame downwards, thereby pressing the raised plate onto the flat cardboard, achieving adhesion. The system also includes a sensor device to detect the position of the raised plate and the flat cardboard, thereby locating the raised plate and the flat cardboard and controlling the temporary stop of the conveyor belt. This can be achieved by using infrared sensors, camera image recognition, or other existing technologies, which will not be elaborated here.

[0007] For further optimization, the pressure plate frame and the recessed block are detachably connected to facilitate maintenance and replacement.

[0008] Further optimization, as a stable and detachable connection method, involves a ring-shaped insert on the circumferential surface of the pressure plate frame, and a ring-shaped slot on the lower surface of the recess that matches the ring-shaped insert. The ring-shaped insert and the ring-shaped slot are connected by bolts. In this design, the pressure plate frame is square, and the ring-shaped insert is also square. The ring-shaped insert can be inserted into the ring-shaped slot for quick positioning and installation. The connection is then achieved by passing bolts laterally through the ring-shaped slot and the ring-shaped insert.

[0009] Further optimization involves placing the bolt on the outer side of the recess, as the inner side of the recess may come into contact with the product. This is achieved by having several threaded holes on the outer circumference of the recess, which pass through the annular slot. The annular insert has through holes that fit the bolt. In this design, the threaded holes pass through the annular slot from the outside but do not penetrate the inner side of the recess. After inserting the pressure plate frame, the bolt is positioned laterally.

[0010] Further optimization involves a vacuum adsorption setup where the pressure plate frame has an internal circumferential chamber, with each negative pressure suction port connected to this chamber. The upper surface of the pressure plate frame has a connection port that connects to the circumferential chamber, allowing connection to an external vacuum adsorption unit. In this design, the external vacuum adsorption unit can be a vacuum pump, which is sealed via pipes and the connection port, thereby connecting to the circumferential chamber and several negative pressure suction ports to achieve adsorption.

[0011] As a redundancy solution, the upper surface of the pressure plate frame is provided with at least two connection ports, and several connection ports are connected to the external vacuum adsorption unit.

[0012] To further optimize the product and avoid hard contact that could damage it, a flexible layer is provided on the lower surface of the pressure plate frame, and the flexible layer has several holes that are compatible with the negative pressure suction port.

[0013] As a redundancy solution, the lifting control unit uses a lifting cylinder.

[0014] A further optimization includes a crossbeam for the fixed lifting control unit, which spans both sides of the conveyor belt, and the lifting control unit is fixed to the crossbeam.

[0015] Further optimization, to improve lifting stability, also includes a rectangular frame, which is fixed to the crossbeam; the rectangular frame includes a first frame and a second frame arranged sequentially from the outside to the inside, and the lifting control unit is fixed inside the second frame; a plurality of sleeves are provided between the first frame and the second frame, and a guide rod is coaxially slidably connected in each sleeve, the lower end of the guide rod is connected to the output end of the lifting control unit, and its length direction is set along the lifting direction of the lifting control unit.

[0016] Compared with the prior art, this utility model has the following advantages and beneficial effects: This invention provides a double-plate pressing device for raised models. By using this solution, the raised plate and the flat cardboard are bonded together through the upward adsorption and downward pressing of the lifting control unit, thereby improving production efficiency.

[0022] Example: This embodiment provides a double-plate pressing device for protruding models, such as... Figures 1-5 As shown, it includes: A lifting control unit 1 is fixed above the conveyor belt with its output end facing downwards; The concave block 2 has a groove in the middle, which is fixed to the output end of the lifting control unit 1, and the opening of the groove faces downward; The pressure plate frame 3 is fixed to the lower side of the concave block 2, and the central channel of the pressure plate frame 3 is connected to the groove; the lower surface of the pressure plate frame 3 is provided with several negative pressure suction ports in the circumferential direction.

[0023] Compared to existing technologies where the bonding between the raised plate 7 and the flat cardboard 8 is typically done manually, resulting in significant waste of manpower and resources and reduced production efficiency, this invention provides a double-plate pressing device for raised models. This solution utilizes the rising adsorption and falling pressing of the lifting control unit 1 to achieve bonding between the raised plate 7 and the flat cardboard 8, thereby improving production efficiency. Specifically, the device includes a lifting control unit 1 fixed above the conveyor belt. The lifting control unit 1 is preferably a lifting cylinder with its output end facing downwards. A recessed block 2 with a groove is fixed at the output end of the lifting control unit 1 and is inverted, with the groove opening facing downwards. A pressure plate frame 3 is provided below the recessed block 2. The pressure plate frame 3 is frame-shaped with a channel in its middle, the channel's size matching the groove and communicating with it. This controls the conveyor belt to alternately transport the raised plate 7 and the flat cardboard 8. When the raised plate 7 moves below the pressure plate frame 3, the conveyor belt stops temporarily, driving the pressure plate frame 3 to press down. At this time, the raised part of the raised plate 7 can enter the groove to avoid obstruction. The negative pressure suction port on the periphery of the pressure plate frame 3 can suck up the raised plate 7 and then move upward to lift the raised plate 7. The conveyor belt continues to drive, and when the glued flat cardboard 8 moves below, the conveyor belt stops again, driving the pressure plate frame 3 to press down, thereby pressing the raised plate 7 onto the flat cardboard 8 to achieve adhesion. A sensor device is also provided to detect the position of the raised plate 7 and the flat cardboard 8 to locate the raised plate 7 and the flat cardboard 8 and control the temporary stop of the conveyor belt. The use of infrared sensors, camera image recognition, etc., is existing technology and will not be described in detail here.

[0024] In some possible embodiments, the pressure plate frame 3 and the recess 2 are detachably connected for easy maintenance and replacement.

[0025] In some possible embodiments, as a stable and detachable connection method, the upper surface of the pressure plate frame 3 has a circumferentially circumferentially oriented annular insert 301, and the lower surface of the recess 2 has an annular slot adapted to the annular insert 301. The annular insert 301 and the annular slot are connected by bolts 4. In this solution, the pressure plate frame 3 is square, and the circumferential insert is also square. The circumferential insert can be inserted into the annular slot to achieve quick positioning and installation. Subsequently, the connection is achieved by the bolts 4 passing laterally through the annular slot and the annular insert 301.

[0026] In some possible embodiments, since the inner side of the recess 2 may come into contact with the product, the bolt 4 needs to be positioned on the outer side. This is achieved by having several threaded holes on the outer circumference of the recess 2, the threaded holes passing through the annular slot; and the annular insert 301 having through holes adapted to the bolt 4. In this solution, the threaded holes pass through the annular slot from the outside but do not penetrate the inner side of the recess 2. After inserting the pressure plate frame 3, the bolt 4 can be positioned laterally.

[0027] In some possible embodiments, as a vacuum adsorption setup, the pressure plate frame 3 has an internal circumferential chamber 302, and each negative pressure suction port is connected to the circumferential chamber 302. The upper surface of the pressure plate frame 3 has a connection port that communicates with the circumferential chamber 302, and this connection port is used to connect to an external vacuum adsorption unit. In this solution, the external vacuum adsorption unit can be a vacuum pump, which is sealed and connected to the circumferential chamber 302 and several negative pressure suction ports through pipes and the connection port to achieve adsorption.

[0028] As a redundancy solution, the upper surface of the pressure plate frame 3 is provided with at least two connection ports, and several connection ports are connected to the external vacuum adsorption unit.

[0029] In some possible embodiments, to avoid hard contact and damage to the product, the lower surface of the pressure plate frame 3 is provided with a flexible layer 303, and the flexible layer 303 has a number of holes adapted to the negative pressure suction port.

[0030] As a redundancy solution, the lifting control unit 1 adopts a lifting cylinder.

[0031] In some possible embodiments, a crossbeam 5 is also included to fix the lifting control unit 1, the crossbeam 5 spanning both sides of the conveyor belt, and the lifting control unit 1 is fixed on the crossbeam 5.

[0032] In some possible embodiments, to improve lifting stability, a rectangular frame 6 is also included, which is fixed to the crossbeam 5. The rectangular frame 6 includes a first frame and a second frame arranged sequentially from the outside to the inside, and the lifting control unit 1 is fixed inside the second frame. A plurality of sleeves 601 are provided between the first frame and the second frame, and a guide rod 602 is coaxially slidably connected in each sleeve 601. The lower end of the guide rod 602 is connected to the output end of the lifting control unit 1, and its length direction is arranged along the lifting direction of the lifting control unit 1.

[0033] How this solution works: The control conveyor belt alternately transports the raised plate 7 and the flat cardboard 8. When the raised plate 7 moves below the pressure plate frame 3, the conveyor belt stops temporarily, driving the pressure plate frame 3 to press down. At this time, the raised part of the raised plate 7 can enter the groove to avoid obstruction. The negative pressure suction port on the periphery of the pressure plate frame 3 can suck up the raised plate 7 and then move upward to lift the raised plate 7. The conveyor belt continues to drive, and when the glued flat cardboard 8 moves below, the conveyor belt stops again, driving the pressure plate frame 3 to press down, thereby pressing the raised plate 7 onto the flat cardboard 8 to achieve adhesion. Then the negative pressure suction port is released, allowing the glued product to be conveyed backward for quality inspection. Repeating the above steps can achieve mass production and improve production efficiency.

[0034] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model.
