Description

Technical Field

[0001] The utility model relates to the technical field of film coating equipment, and more specifically, it relates to a precisely positioned pre-coating film machine. Background Art

[0002] Laminating machine usually refers to the equipment used to laminate the cardboard, which can prolong the service life of the cardboard by adhering the laminating film to the cardboard.

[0003] When laminating cardboard with an existing laminating machine, the staff usually fixes the film on the roller, then pulls the film to drive the film, the heating roller and the pressing roller to contact each other, and then the staff manually places the cardboard on the conveyor belt in turn, and the conveyor belt can move the cardboard toward the pressing roller, and at the same time drive several rollers in the laminating machine to start rotating, so that the film starts to move toward the pressing roller. At this time, the heating roller softens the film, and when the cardboard and the pressing roller contact each other, the pressing roller presses the softened film onto the surface of the cardboard. Since the softened film itself has a certain viscosity, the film can adhere to the surface of the cardboard, thereby completing the process of laminating the cardboard.

[0004] However, when placing the cardboard on the conveyor belt, the staff needs to place the cardboard manually, which causes the cardboard to be skewed during placement. When the skewed cardboard and the coating come into contact with each other, the coating cannot completely cover the cardboard, resulting in a lower pass rate for the cardboard after coating, affecting the coating effect.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0006] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a precisely positioned pre-coating machine, which solves the problem that when the position of the cardboard is skewed, the laminating film cannot completely cover the cardboard, thus affecting the laminating effect.

[0007] The above technical objectives of the utility model are achieved through the following technical solutions: a precisely positioned pre-coating film machine, comprising a frame and a conveyor belt, a heating roller, a pressing roller and a plurality of rollers located on the frame, the frame being rotatably connected with two rotating plates, the two rotating plates being in contact with the top of the conveyor belt respectively, the two rotating plates being fixedly connected with two limit blocks on one side away from the frame respectively, the two rotating plates being close to their own rotation direction respectively provided with limit grooves for sliding connection of the two limit blocks, the two rotating plates being rotatably connected with connecting plates, the connecting plates being provided with a restoring component for driving the two rotating plates back to their original positions, and the frame being provided with a fixing component for preventing the cardboard from being offset.

[0008] By adopting the above technical solution, when the cardboard surface needs to be transported, the cardboard is placed on the conveyor belt, and the conveyor belt is started at the same time to drive the cardboard to start moving in the direction of the two rotating plates. When the cardboard is in a skewed state, the side wall of the cardboard will preferentially contact the side wall of one of the rotating plates, and apply a thrust to one of the rotating plates. At this time, one of the rotating plates is restricted by the upper limit block of the other rotating plate and cannot rotate. At the same time, the cardboard is continued to be pushed by the conveyor belt to drive the side wall of the cardboard to completely fit together with the two rotating plates, and a thrust is applied to the two rotating plates at the same time. At this time, the limit blocks on the two rotating plates lose their restrictions and separate from the limit grooves, and the two rotating plates are driven at the same time. The movable plate starts to rotate and drives the cardboard on the conveyor belt to continue to move forward. After the cardboard completely passes through the two rotating plates, the two rotating plates can be driven back to their original positions through the recovery component, and the two limit blocks can be driven to re-enter the limit grooves. At the same time, the cardboard can be fixed during the subsequent movement of the cardboard through the fixing component to avoid the position of the cardboard being offset during movement, thereby completing the effect of conveying the cardboard. Through the setting of the two rotating plates, the position of the cardboard in the skewed state can be adjusted to make the cardboard and the coating parallel to each other, thereby avoiding the problem that the coating cannot completely cover the cardboard, improving the qualified rate while reducing the generation of waste and improving the environmental protection effect.

[0009] The utility model is further configured as follows: the restoration component includes two rotating rods rotatably connected to the connecting plate, the two rotating rods both penetrate the connecting plate and are fixedly connected to the rotating plate, the side walls of the two rotating rods are fixedly connected with two synchronous wheels, the two synchronous wheels are connected by belts, the belts are staggered, a fixed plate is fixedly connected to the frame, a motor is fixedly connected to the side wall of the fixed plate, and the output end of the motor is fixedly connected to one of the rotating rods.

[0010] By adopting the above technical solution, when it is necessary to drive the two rotating plates back to their original positions after rotation, the motor is started, and the output end of the motor is driven to drive one of the synchronous wheels to start rotating. At the same time, one of the synchronous wheels drives the belt to rotate, and the other synchronous wheel can be driven to rotate through the belt. At this time, due to the staggered arrangement of the belts, the two synchronous wheels start to rotate in opposite directions. Therefore, while the two synchronous wheels rotate, the two rotating rods can drive the two rotating plates to rotate synchronously, and drive the limit blocks on the two rotating plates to enter the limit grooves, thereby achieving the effect of driving the two rotating plates back to their original positions.

[0011] The utility model is further configured as follows: the fixed assembly includes a plurality of support frames fixedly connected to the frame, a plurality of the support frames are provided with slide grooves, two moving rods are slidably connected in the slide grooves, the bottoms of the two moving rods are rotatably connected with pressing wheels, the pressing wheels and the conveyor belt are in contact with each other, and a driving member for driving the moving rods to move synchronously along the slide grooves is provided between the two moving rods.

[0012] By adopting the above technical solution, after the cardboard passes through the two rotating plates, the two moving rods on the support frame are driven by the driving member to start sliding along the slide groove, so that the spacing between the two moving rods matches the width of the cardboard. When the cardboard moves to contact with the pressing wheel, the two moving rods are affected by the thickness of the cardboard and start moving upward, while lifting the pressing wheel. At this time, the weight of the pressing wheel and the moving rods themselves can apply pressure to the cardboard, thereby avoiding the problem of the position of the cardboard being offset.

[0013] The utility model is further configured as follows: the driving member includes a bidirectional screw, and two threaded holes are respectively opened on the side walls of the two moving rods, one of the threaded holes is threadedly connected to the left thread of the bidirectional screw, and the other threaded hole is threadedly connected to the right thread of the bidirectional screw, a limit plate is fixedly connected to the frame, and a plurality of the bidirectional screws are rotatably connected to the limit plates.

[0014] By adopting the above technical solution, when the two moving rods need to be driven to move, the two moving rods can be driven to move synchronously through the setting of the bidirectional screw rod, so that the distance between the two moving rods can be adjusted.

[0015] The utility model is further configured as follows: a plurality of the bidirectional screw side walls are respectively fixedly connected with gears, and two adjacent gears are meshed with each other.

[0016] By adopting the above technical solution, when one of the bidirectional screws rotates, one of the bidirectional screws will drive the gear connected to itself to start rotating, and at the same time the gear will drive another gear meshing with itself to start rotating, and the other gear will drive the other bidirectional screw to start rotating, thereby achieving the effect of driving several bidirectional screws to rotate synchronously, which can reduce the operating steps of the staff when adjusting the moving rod and improve work efficiency.

[0017] The utility model is further configured as follows: the side walls of the two moving rods are fixedly connected with a limiting piece, and when the limiting piece and the top of the support frame are in contact with each other, the pressing wheel and the top of the conveyor belt are in contact with each other.

[0018] By adopting the above technical solution, the moving position of the moving rod can be limited, so as to avoid the moving rod from tilting during the movement, thereby improving the stability of the moving rod during the movement.

[0019] The utility model is further configured as follows: one end of one of the bidirectional screws is fixedly connected with a holding block.

[0020] By adopting the above technical solution, it is possible to facilitate driving the bidirectional screw to rotate.

[0021] In summary, the utility model has the following beneficial effects: when the cardboard is in a skewed state, the side wall of the cardboard will preferentially contact the side wall of one of the rotating plates. At this time, one of the rotating plates is restricted by the upper limit block on the other rotating plate and cannot rotate. At the same time, the cardboard continues to be pushed, driving the side wall of the cardboard to completely fit together with the two rotating plates, and at the same time, a thrust is applied to the two rotating plates. At this time, the limit blocks on the two rotating plates lose their restrictions, driving the two rotating plates to start rotating, and driving the cardboard on the conveyor belt to move forward, thereby completing the effect of conveying the cardboard. Through the arrangement of the two rotating plates, the position of the cardboard in the skewed state can be adjusted, so that the cardboard and the coating are parallel to each other, thereby avoiding the problem that the coating cannot completely cover the cardboard. While improving the qualified rate, it can also reduce the generation of waste and improve the environmental protection effect. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0030] Precisely positioned pre-coating machines, such as Figure 1-Figure 4 As shown, it includes a frame 1 and a conveyor belt 2, a heating roller 3, a pressing roller 4 and a plurality of rollers 5 located on the frame 1. Two rotating plates 6 are rotatably connected to the frame 1. The two rotating plates 6 are in contact with the top of the conveyor belt 2 respectively. Two limit blocks 7 are fixedly connected to the sides of the two rotating plates 6 away from the frame 1 respectively. Limit grooves 8 for sliding connection of the two limit blocks 7 are respectively provided on the sides of the two rotating plates 6 close to their own rotation direction. Connecting plates 9 are rotatably connected to the two rotating plates 6. The connecting plates 9 are provided with a restoring component for driving the two rotating plates 6 back to their original positions. A fixing component for preventing the cardboard from being offset is provided on the frame 1. When the surface of the cardboard needs to be transported, the cardboard is placed above the conveyor belt 2, and the conveyor belt 2 is started at the same time to drive the cardboard to start moving in the direction of the two rotating plates 6.

[0031] When the cardboard is in a skewed state, the side wall of the cardboard will preferentially contact the side wall of one of the rotating plates 6 and apply a thrust to one of the rotating plates 6. At this time, one of the rotating plates 6 is restricted by the other rotating plate 6 and cannot rotate. At the same time, the cardboard is continued to be pushed by the conveyor belt 2, driving the side wall of the cardboard to completely fit together with the two rotating plates 6, and applying a thrust to the two rotating plates 6 at the same time. At this time, the limit blocks 7 on the two rotating plates 6 lose their restrictions and separate from the limit grooves 8, driving the two rotating plates 6 to start rotating at the same time, and driving the cardboard on the conveyor belt 2 to continue moving forward.

[0032] After the cardboard has completely passed through the two rotating plates 6, the two rotating plates 6 can be driven back to their original positions by the restoration component, and the two limit blocks 7 can be driven to re-enter the limit grooves 8. At the same time, the cardboard can be fixed during the subsequent movement of the cardboard by the fixing component to avoid the position of the cardboard being shifted during the movement, thereby completing the effect of conveying the cardboard. Through the arrangement of the two rotating plates 6, the position of the cardboard in a skewed state can be adjusted to make the cardboard and the coating parallel to each other, thereby avoiding the problem that the coating cannot completely cover the cardboard, thereby improving the qualified rate and reducing the generation of waste, thereby improving the environmental protection effect.

[0033] like Figure 1-Figure 4 As shown, the recovery assembly includes two rotating rods 10 rotatably connected to the connecting plate 9, the two rotating rods 10 both penetrate the connecting plate 9 and are fixedly connected to the rotating plate 6, the side walls of the two rotating rods 10 are fixedly connected to two synchronous wheels 11, the two synchronous wheels 11 are connected by belts 12, the belts 12 are staggered, a fixed plate 13 is fixedly connected to the frame 1, a motor 14 is fixedly connected to the side wall of the fixed plate 13, the output end of the motor 14 is fixedly connected to one of the rotating rods 10, and when it is necessary to drive the two rotating plates 6 to return to their original positions after rotation, the motor 14 is started to drive The output end of the motor 14 drives one of the synchronous wheels 11 to start rotating, and at the same time, one of the synchronous wheels 11 drives the belt 12 to rotate, and the belt 12 can drive the other synchronous wheel 11 to rotate. At this time, due to the staggered arrangement of the belts 12, the two synchronous wheels 11 start to rotate in opposite directions. Therefore, while the two synchronous wheels 11 rotate, the two rotating plates 6 can be driven to rotate synchronously through the two rotating rods 10, and the limit blocks 7 on the two rotating plates 6 are driven to enter the limit grooves 8, so as to achieve the effect of driving the two rotating plates 6 back to their original positions.

[0034] like Figure 1-Figure 4As shown, the fixed assembly includes a plurality of support frames 15 fixedly connected to the frame 1, a plurality of support frames 15 are provided with a slide groove 16, two moving rods 17 are slidably connected in the slide groove 16, and a pressing wheel 18 is rotatably connected at the bottom of the two moving rods 17, and the pressing wheel 18 and the conveyor belt 2 are in contact with each other. A driving member for driving the moving rods 17 to move synchronously along the slide groove 16 is provided between the two moving rods 17, and the driving member includes a bidirectional screw 19, and two threaded holes 20 are respectively provided on the side walls of the two moving rods 17, wherein one threaded hole 20 is threadedly connected to the left thread of the bidirectional screw 19, and the other threaded hole 20 is threadedly connected to the right thread of the bidirectional screw 19. A limit plate 24 is fixedly connected to the frame 1, and a plurality of bidirectional screws 19 are rotatably connected to the limit plate 24. After the cardboard passes through the two rotating plates 6, the two moving rods 17 on the support frame 15 are driven by the bidirectional screws 19 to start sliding along the slide groove 16, so that the spacing between the two moving rods 17 matches the width of the cardboard. When the cardboard moves to contact the pressing wheel 18, the two moving rods 17 are affected by the thickness of the cardboard and start moving upward, while lifting the pressing wheel 18. At this time, the weight of the pressing wheel 18 and the moving rod 17 can apply pressure to the cardboard to avoid the problem of the position of the cardboard being offset.

[0035] The side walls of several bidirectional screws 19 are respectively fixedly connected with gears 21, and two adjacent gears 21 are meshed with each other. When one of the bidirectional screws 19 rotates, one of the bidirectional screws 19 will drive the gear 21 connected to itself to start rotating, and at the same time, the gear 21 will drive another gear 21 meshed with itself to start rotating, and the other bidirectional screw 19 is driven to rotate by the other gear 21, so as to achieve the effect of driving several bidirectional screws 19 to rotate synchronously, which can reduce the operating steps of the staff when adjusting the moving rod 17 and improve work efficiency. The side walls of the two moving rods 17 are fixedly connected with a limiting plate 22. When the limiting plate 22 and the top of the support frame 15 are in contact with each other, the pressing wheel 18 and the top of the conveyor belt 2 contact each other, which can limit the moving position of the moving rod 17, avoid the moving rod 17 from tilting during the movement, and improve the stability of the moving rod 17 during movement. One end of one of the bidirectional screws 19 is fixedly connected with a gripping block 23, which can facilitate the driving of the bidirectional screw 19 to rotate.

[0036] The utility model is used normally as follows: when the cardboard surface needs to be transported, the cardboard is placed above the conveyor belt 2, and the conveyor belt 2 is started at the same time, driving the cardboard to start moving in the direction of the two rotating plates 6. When the cardboard is in a skewed state, the side wall of the cardboard will preferentially contact the side wall of one of the rotating plates 6, and apply a thrust to one of the rotating plates 6. At this time, one of the rotating plates 6 is restricted by the upper limit block 7 on the other rotating plate 6 and cannot rotate. At the same time, the cardboard is continued to be pushed by the conveyor belt 2, driving the side wall of the cardboard to completely fit together with the two rotating plates 6, and applying a thrust to the two rotating plates 6 at the same time. At this time, the limit blocks 7 on the two rotating plates 6 lose their restrictions and separate from the limit grooves 8, driving the two rotating plates 6 to start rotating, and driving the cardboard on the conveyor belt 2 to continue moving forward.

[0037] After the cardboard completely passes through the two rotating plates 6, the motor 14 is started, and the output end of the motor 14 is driven to drive one of the synchronous wheels 11 to start rotating. At the same time, one of the synchronous wheels 11 drives the belt 12 to rotate, and the belt 12 can drive the other synchronous wheel 11 to rotate. At this time, due to the staggered arrangement of the belts 12, the two synchronous wheels 11 start to rotate in opposite directions. Therefore, while the two synchronous wheels 11 rotate, the two rotating rods 10 can drive the two rotating plates 6 to rotate synchronously, and drive the limit blocks 7 on the two rotating plates 6 to enter the limit grooves 8. At the same time, the two moving rods 17 on the support frame 15 are driven to slide along the slide grooves 16 through the bidirectional screw 19, so that the two moving rods 1 The spacing between the two moving rods 17 is consistent with the width of the cardboard. When the cardboard moves to contact the pressing wheel 18, the two moving rods 17 are affected by the thickness of the cardboard and start to move upward, while lifting the pressing wheel 18. At this time, the weight of the pressing wheel 18 and the moving rods 17 can exert pressure on the cardboard, so that it is fixed during the subsequent movement of the cardboard to avoid the position of the cardboard being shifted when moving, thereby completing the effect of conveying the cardboard. Through the arrangement of the two rotating plates 6, the position of the cardboard in the skewed state can be adjusted to make the cardboard and the coating parallel to each other, thereby avoiding the problem that the coating cannot completely cover the cardboard, improving the qualified rate while reducing the generation of waste and improving the environmental protection effect.

[0038] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
