Description

Technical Field

[0001] This utility model relates to the field of gluing machine technology, and in particular to an upper-feed gluing machine. Background Technology

[0002] A laminating machine, also known as a sealing machine, mainly consists of a drive system, a heating and temperature control system, an operation control panel, and front and rear adhesive rollers. It is a specialized device for laminating photos or documents. Existing laminating machines typically have a through-hole at the front and rear for horizontally inserting laminated photos or documents. They can either insert from the rear and output from the front, or vice versa. Figure 1 As shown in the diagram, sufficient space needs to be left both in front of and behind the equipment. Therefore, existing laminating machines have requirements for the space they can be placed in. For workbenches with limited space, the laminating machine is placed against the back panel of the workbench or against a wall, and then moved to a more spacious area, such as a suitable tabletop, before being returned to the workbench after use. Therefore, existing laminating machines need to be optimized and improved so that they can be placed against the back panel of the workbench or against a wall while still functioning normally, reducing their space requirements. Utility Model Content

[0003] In view of this, the present invention proposes a top-feed gluing machine, which can be placed against the back panel of the table or against the wall and can be used normally.

[0004] The technical solution of this utility model is an upward-feeding gluing machine, including an upper shell, a lower shell, a gluing mechanism disposed within the upper and lower shells, and a control main board. The gluing mechanism includes a hot press roller assembly, a heating unit, a drive motor, a drive gear, and a synchronous gear. The upper and lower shells have an output port on their front sides, and the top surface of the upper shell near the rear side has an upward-feeding input port. The lower end of the upward-feeding input port has a curved upper guide plate and a curved lower guide plate, forming a curved channel between them. The front end of the curved channel is a horizontal output port. The material to be glued enters through the upward-feeding input port, passes through the horizontal output port, and then enters the hot press roller assembly horizontally.

[0005] Furthermore, the upper feed inlet includes a front sidewall and a rear sidewall. The front sidewall is formed by bending the rear end of the top surface of the upper housing downwards. The front sidewall and the rear sidewall form an upper feed inlet with an outward expansion at the top.

[0006] Furthermore, the rear side wall of the insertion port is provided with a step along the length of the upper feed inlet on the upper side of the upper housing. A flip-top back plate is provided on the step. Pivot rods are provided on the left and right sides of the back plate. The left and right side walls of the upper housing corresponding to the upper feed inlet are provided with pivot holes for pivoting with the pivot rods. The back plate is used to provide back support and guidance for the inserted material to be glued.

[0007] Furthermore, the pivot hole is an oblong hole, which consists of two through holes connected by an arc-shaped hole. The two through holes are the upper and lower ends of the oblong hole, respectively. When the back panel is in the open state, the pivot rod of the back panel is connected to the lower end of the oblong hole, and the lower edge of the back panel abuts against the step. When the back panel is closed, the back panel is lifted, and the pivot rod runs along the oblong hole from the lower end to the upper end. The lower edge of the back panel and the rear side of the step form a flipping space.

[0008] Furthermore, the hot press roller assembly includes an upper hot laminating roller and a lower hot laminating roller, and the heating unit includes an upper heating unit and a lower heating unit. Both the upper heating unit and the lower heating unit use an aluminum alloy substrate as the heat-conducting body. The front side of the aluminum alloy substrate is provided as a curved cover, and the rear side is provided as an inclined slot that is integrally connected to the curved cover. A heating element is provided in the slot, and the heating element is electrically connected to the control main board. The upper heating unit covers the upper front side and the rear side of the upper hot laminating roller, and the lower heating unit covers the lower front side and the rear side of the lower hot laminating roller. The bottom of the slot of the upper heating unit and the top of the slot of the lower heating unit form an inlet channel for gluing.

[0009] Furthermore, an outlet plate is provided in front of the upper and lower hot mounting rollers. The outlet plate includes a horizontal part and a downward sloping part. The rear end of the sloping part is close to the side of the lower hot mounting roller. The sloping part is lower than the height at which the upper and lower hot mounting rollers press against each other. The height of the horizontal part is the same as the height at which the upper and lower hot mounting rollers press against each other. The front end of the outlet plate is connected to the output port.

[0010] Furthermore, an inlet roller assembly is provided behind the inlet channel, the inlet roller assembly including an upper inlet roller and a lower inlet roller. The upper and lower inlet rollers are in close contact with each other and rotate in opposite directions. The feed inlet formed by the upper and lower inlet rollers is connected to the horizontal output port, and the discharge port formed by the upper and lower inlet rollers is connected to the inlet channel formed by the upper heating unit and the lower heating unit.

[0011] Furthermore, a guide channel is provided between the discharge port formed by the upper and lower guide rollers and the inlet channel. The guide channel is composed of an upper guide plate and a lower guide plate. The upper and lower guide plates are both horizontal in the middle and sloping in the same direction on the front and rear sides. The upper and lower guide plates are arranged in parallel and opposite directions to form an outwardly flared opening at the front and rear ends of the guide channel. The horizontal surface of the lower guide plate is at the same horizontal height as the top of the slot of the lower heating unit.

[0012] Furthermore, the gluing mechanism also includes a left support plate and a right support plate. The left support plate and the right support plate are respectively used to connect the left and right ends of the upper hot mounting roller, the lower hot mounting roller, the upper heating unit, the lower heating unit, the curved guide plate, the curved lower guide plate, the upper inlet roller, the lower inlet roller, the upper guide plate, the lower guide plate, and the outlet plate. The left support plate and the right support plate are respectively provided with shaft holes connecting the left and right ends of the upper hot mounting roller, the lower hot mounting roller, the upper inlet roller, and the lower inlet roller. A drive gear is provided on the outer side of the left support plate. The drive gear is driven by a drive motor. The left ends of the upper hot mounting roller and the lower hot mounting roller are provided with meshing hot mounting roller synchronous gears. The left ends of the upper inlet roller and the lower inlet roller are provided with meshing inlet roller synchronous gears. The drive gear meshes with the hot mounting roller synchronous gear of the lower hot mounting roller and the inlet roller synchronous gear of the lower inlet roller.

[0013] The disclosed top-feed gluing machine has the advantage of having an top-feed inlet located near the rear of the upper housing. The material to be glued is inserted through this inlet, allowing for top-feed placement. The material is then bent through a curved channel and output horizontally through a horizontal outlet before entering the hot press roller assembly for hot pressing. Compared to existing gluing machines with rear-entry and front-exit designs, this machine does not have a rear inlet / outlet. Instead, the top-feed inlet is located on the top surface of the upper housing near the rear, with an upward-facing opening. Combined with the curved channel below the inlet, this allows the material to be glued to be placed from top to bottom, then bent and fed horizontally forward to the hot press roller assembly. Therefore, this gluing machine can be used normally when placed against a back panel of a table or against a wall, reducing space limitations. Attached Figure Description

[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 also within the protection scope of this utility model.

[0026] Please refer to Figures 2 to 8This is a specific embodiment of an upward-feeding gluing machine disclosed in this technical solution, including an upper housing 1, a lower housing 2, a gluing mechanism 3 disposed in the upper housing 1 and the lower housing 2, and a control main board. The gluing mechanism 3 includes a hot press roller group, a heating unit, a drive motor, and a drive gear 7. An output port 101 is provided on the front side of the upper housing 1 and the lower housing 2. An upward feed input port 102 is provided on the top surface of the upper housing 1 near the rear side. A curved upper guide plate 5 and a curved lower guide plate 6 are respectively provided at the lower end of the upward feed input port 102. A curved channel 561 is formed between the curved upper guide plate 5 and the curved lower guide plate 6. The front end of the curved channel 561 is a horizontal output port 562. The material to be glued enters from the upward feed input port 102, passes through the horizontal output port 562, and enters the hot press roller group in a horizontal position.

[0027] Please refer to Figure 5 The upper feed inlet 102 includes a front sidewall and a rear sidewall. The front sidewall is formed by bending the rear end of the top surface of the upper housing 1 downward to form a curved front sidewall 1021. The front sidewall and the rear sidewall form an upper feed inlet 102 with an outward expansion at the top, which facilitates the insertion of the material to be glued.

[0028] Please refer to Figure 2 , Figures 5 to 7 The upper side wall of the insertion port is provided with a step position 1022 along the length direction of the upper feed inlet 102 near the upper side of the upper housing 1. A flip-top back plate 4 is provided on the step position 1022. Pivot rods 401 are provided on the left and right sides of the back plate 4 respectively. The upper housing 1 is provided with pivot holes 103 on the left and right side walls corresponding to the upper feed inlet 102, which are pivotally connected to the pivot rods 401. The back plate 4 is used to provide back support and guidance for the inserted object to be glued.

[0029] Please refer to Figures 5 to 8 Furthermore, the pivot hole 103 is an oblong hole, consisting of two through holes connected by an arc-shaped opening. The two through holes are the upper and lower ends of the oblong hole, respectively. When the backrest plate 4 is in the open state, the pivot rod 401 of the backrest plate 4 is connected to the lower end of the oblong hole, and the lower edge of the backrest plate 4 abuts against the step 1022. Normally, the backrest plate 4 cannot be closed because its lower edge and rear side abut against the rear side of the step 1022, leaving no room for folding. When it is necessary to close the backrest plate 4, it is first lifted, and the pivot rod 401 moves along the oblong hole from the lower end to the upper end. The lower edge of the backrest plate 4 is lifted upwards, creating a folding space between the lower edge of the backrest plate 4 and the rear side of the step 1022, thus allowing the backrest plate 4 to be closed. Figure 7 (As shown). This structural design ensures that the back panel 4 provides excellent stability when opened, preventing it from being easily flipped over and closed.

[0030] Please refer to Figure 3 , Figure 5 The hot press roller assembly includes an upper hot laminating roller 31 and a lower hot laminating roller 32. The heating unit includes an upper heating unit 33 and a lower heating unit 34.

The front side of the aluminum alloy substrate is provided as a curved cover, and the rear side is provided as an inclined slot that is integrally connected to the curved cover. A heating element is provided in the slot, and the heating element is electrically connected to the control main board. The upper heating unit 33 covers the upper front side and the rear side of the upper hot laminating roller 31, and the lower heating unit 34 covers the lower front side and the rear side of the lower hot laminating roller 32. The bottom of the slot of the upper heating unit 33 and the top of the slot of the lower heating unit 34 form an inlet channel for gluing.

[0031] Please refer to Figures 3 to 6 In this embodiment, a guide plate 35 is further provided in front of the upper hot mounting roller 31 and the lower hot mounting roller 32. The guide plate 35 includes a horizontal part and a downward sloping part. The rear end of the sloping part is close to the side of the lower hot mounting roller 32. The sloping part is lower than the height at which the upper hot mounting roller 31 and the lower hot mounting roller 32 press against each other. The height of the horizontal part is the same as the height at which the upper hot mounting roller 31 and the lower hot mounting roller 32 press against each other. The front end of the guide plate 35 is connected to the output port 101.

[0032] Please refer to Figure 3 , Figure 5 In this embodiment, further, an inlet roller group is provided behind the inlet channel, the inlet roller group including an upper inlet roller 36 and a lower inlet roller 37. The upper and lower roller surfaces of the upper inlet roller 36 and the lower inlet roller 37 are in close contact and rotate in opposite directions. The feed port formed by the upper inlet roller 36 and the lower inlet roller 37 is connected to the horizontal output port 562, and the discharge port formed by the upper inlet roller 36 and the lower inlet roller 37 is connected to the inlet channel formed by the upper heating unit 33 and the lower heating unit 34. Preferably, a guide channel is provided between the discharge port formed by the upper guide roller 36 and the lower guide roller 37 and the inlet channel. The guide channel is composed of an upper guide plate 38 and a lower guide plate 39. Both the upper guide plate 38 and the lower guide plate 39 have a horizontal plate surface in the middle and sloping plate surfaces inclined to the same side on the front and rear sides. The upper guide plate 38 and the lower guide plate 39 are arranged parallel to each other vertically, forming an outwardly flared opening at the front and rear ends of the guide channel. The horizontal plate surface of the lower guide plate 39 is at the same horizontal height as the top of the slot portion of the lower heating unit 34. By setting the guide channel, after the material to be glued enters from the guide roller group, it can better enter the inlet channel of the heating unit, thereby smoothly entering the hot press roller group.

[0033] Please refer to Figures 2 to 4Furthermore, the gluing mechanism 3 also includes a left support plate and a right support plate. The left and right support plates are respectively used to connect the left and right ends of the upper hot laminating roller 31, lower hot laminating roller 32, upper heating unit 33, lower heating unit 34, curved guide plate 5, curved lower guide plate 6, upper guide roller 36, lower guide roller 37, upper guide plate 38, lower guide plate 39, and exit plate 35. The left and right support plates are respectively provided with shaft holes connecting the left and right ends of the upper hot laminating roller 31, lower hot laminating roller 32, upper guide roller 36, and lower guide roller 37. A drive gear 7 is provided on the outer side of the left support plate, and the drive gear 7 is driven by a drive motor. The upper hot laminating roller 31 and lower hot laminating roller 32... The left end is provided with a meshing hot mounting roller synchronous gear 8, the left end of the upper guide roller 36, and the left end of the lower guide roller 37 is provided with a meshing guide roller synchronous gear 9. The drive gear 7 meshes with the hot mounting roller synchronous gear 8 of the lower hot mounting roller 32 and the guide roller synchronous gear 9 of the lower guide roller 37. The right end of the lower guide roller 37 and the upper guide roller 36 is provided with a meshing guide roller synchronous gear 9, so that the drive motor drives the drive gear 7 to rotate, and the drive gear 7 drives the hot mounting synchronous gear of the lower hot mounting roller 32 and the guide roller synchronous gear 9 of the lower guide roller 37 to rotate. At the same time, the hot mounting roller synchronous gear 8 of the lower hot mounting roller 32 drives the upper hot mounting roller 31, and the guide roller synchronous gear 9 of the lower guide roller 37 drives the upper guide roller 36.

[0034] In this embodiment, an upper feed inlet 102 is provided on the upper housing 1 of the gluing machine near the rear side. The material to be glued is inserted through the upper feed inlet 102, achieving upper feed placement. The material is bent through a bending channel 561 and then output horizontally through a horizontal output port 562 before entering the hot press roller group for hot pressing. The rear end of the gluing machine does not have an inlet or outlet; instead, it is located on the top surface of the upper housing 1 near the rear side, with the upper feed inlet 102 opening upwards. This, combined with the bending channel 561 at the lower end of the upper feed inlet 102, allows the material to be glued to be placed from top to bottom, then bent to form a horizontal forward input to the hot press roller group. Therefore, this gluing machine can be used normally when its rear end rests against the back panel of the placement table or against a wall, reducing space limitations.
