[0001] This utility model relates to the field of laminating machine technology, and in particular to a laminating machine. Background Technology

[0002] Currently, the laminating machine has two laminating shafts (also called hot mounting shafts, hot mounting wheels, etc.) at the front end and two rollers at the rear end. The two laminating shafts are used to heat and press the film, so that the softened film is tightly bonded to the product to form a laminated product, while the two rollers are used to carry the laminated product from front to back.

[0003] The problem with existing technology is that:

[0011] Furthermore, the inner side of the first bracket is provided with two protruding support plates, which are distributed front to back. Two through holes distributed front to back are provided between the two support plates. The tension spring is located above the two support plates, and the latch is located between the two support plates. The front and rear side walls of the latch are rotatably connected to the two support plates respectively. The top of the latch is connected to the tension spring. The bottom of the latch is provided with two self-locking plates, which pass through the two through holes and abut against one end of the fifth gear.

[0012] Furthermore, the second gear and the fourth gear are located outside the second bracket, and heating tubes are respectively provided inside the first coating shaft and the second coating shaft; a plurality of annular protrusions are provided on both the first roller shaft and the second roller shaft, and annular grooves are formed between adjacent annular protrusions. The annular protrusions and annular grooves on the first roller shaft correspond one-to-one with the annular grooves and annular protrusions on the second roller shaft.

[0013] Furthermore, a base plate is connected between the bottom ends of the first support and the second support, and a detection device is provided on the base plate.

[0016] In summary, the technical solution of this utility model has the following beneficial effects: The structure of this utility model is reasonable. (1) By setting a first support and a second support, a first roller shaft, a second roller shaft, a first coating shaft, and a second coating shaft are rotatably connected between the first support and the second support. The first coating shaft and the second coating shaft have heating functions. The two ends of the first roller shaft are respectively fitted with a first gear, one end of the second roller shaft is fitted with a second gear, the two ends of the first coating shaft are respectively fitted with a third gear, and one end of the second coating shaft is fitted with a fourth gear. The first gear meshes with the second gear, and the third gear meshes with the fourth gear; thus, the first roller shaft and the second roller shaft rotate in opposite directions, allowing the coated product to pass through the gap between the first roller shaft and the second roller shaft, carrying the coated product from front to back. The first coating shaft and the second coating shaft rotate in opposite directions, allowing the film and the product to pass through the gap between the first coating shaft and the second coating shaft. At the same time, the first coating shaft and the second coating shaft heat and pressurize the film, so that the softened film adheres tightly to the product, forming a coated product. (2) By setting a latch on the inner side of the first bracket and a fifth gear on the outer side of the first bracket, the first gear, the third gear and the fifth gear mesh and drive each other. The latch passes through the first bracket and abuts against one end of the fifth gear, and the other end of the fifth gear abuts against the spring. The latch can push the fifth gear to move in the direction of the spring so that the fifth gear disengages from the first gear and the third gear. Thus, when the latch is locked, the fifth gear, as the driving gear, will drive the first gear, the second gear, the third gear and the fourth gear to rotate through meshing and drive each other, thereby realizing the normal operation of the first roller shaft, the second roller shaft, the first coating shaft and the second coating shaft. When the latch is unlocked, the latch pushes the fifth gear to move in the direction of the spring until the fifth gear disengages from the first gear and the third gear. At this time, the first roller shaft, the second roller shaft, the first coating shaft and the second coating shaft can rotate freely. Thus, when the film is entangled with the coating shaft and the roller shaft (or when other faults need to be eliminated), it will be very easy to handle. Analysis shows that this invention can simultaneously lock and unlock the first coating shaft, the second coating shaft, the first roller shaft, and the second roller shaft by locking and unlocking the latch.

[0030] See Figures 1 to 10This embodiment provides a laminating machine, including a first support 1 and a second support 2. A first roller 3, a second roller 4, a first laminating shaft 5, and a second laminating shaft 6 are rotatably connected between the first support 1 and the second support 2. The first laminating shaft 5 and the second laminating shaft 6 have a heating function. A first gear 7 is sleeved at both ends of the first roller 3, a second gear 8 is sleeved at one end of the second roller 4, a third gear 9 is sleeved at both ends of the first laminating shaft 5, and a fourth gear 10 is sleeved at one end of the second laminating shaft 6. Gear 7 meshes with gear 8, and gear 9 meshes with gear 10. A latch 11 is provided on the inner side of the first bracket 1, and a fifth gear 12 is provided on the outer side of the first bracket 1. Gear 7, gear 9 and gear 12 mesh and drive each other. The latch 11 passes through the first bracket 1 and abuts against one end of the fifth gear 12. The other end of the fifth gear 12 abuts against the spring 13. The latch 11 can push the fifth gear 12 to move towards the spring 13 so that the fifth gear 12 disengages from gear 7 and gear 9. Function: (1) By setting up a first support and a second support, the first support and the second support are rotatably connected by a first roller shaft, a second roller shaft, a first coating shaft and a second coating shaft. The first coating shaft and the second coating shaft have heating functions. The first roller shaft is fitted with a first gear at both ends, the second roller shaft is fitted with a second gear at one end, the first coating shaft is fitted with a third gear at both ends, and the second coating shaft is fitted with a fourth gear at one end. The first gear meshes with the second gear, and the third gear meshes with the fourth gear. Thus, the first roller shaft and the second roller shaft rotate in opposite directions, so that the coated product can pass through the gap between the first roller shaft and the second roller shaft, and the coated product moves from front to back. The first coating shaft and the second coating shaft rotate in opposite directions, so that the gap between the first coating shaft and the second coating shaft can allow the film and the product to pass through. At the same time, the first coating shaft and the second coating shaft heat and pressurize the film, so that the softened film and the product are tightly bonded together to form a coated product. (2) By setting a latch on the inner side of the first bracket and a fifth gear on the outer side of the first bracket, the first gear, the third gear and the fifth gear mesh and drive each other. The latch passes through the first bracket and abuts against one end of the fifth gear, and the other end of the fifth gear abuts against the spring. The latch can push the fifth gear to move in the direction of the spring so that the fifth gear disengages from the first gear and the third gear. Thus, when the latch is locked, the fifth gear, as the driving gear, will drive the first gear, the second gear, the third gear and the fourth gear to rotate through meshing and drive each other, thereby realizing the normal operation of the first roller shaft, the second roller shaft, the first coating shaft and the second coating shaft. When the latch is unlocked, the latch pushes the fifth gear to move in the direction of the spring until the fifth gear disengages from the first gear and the third gear. At this time, the first roller shaft, the second roller shaft, the first coating shaft and the second coating shaft can rotate freely. Thus, when the film is entangled with the coating shaft and the roller shaft (or when other faults need to be eliminated), it will be very easy to handle.Analysis shows that this invention can simultaneously lock and unlock the first coating shaft, the second coating shaft, the first roller shaft, and the second roller shaft by locking and unlocking the latch.

[0031] Specifically, a motor 14 is also provided on the outer side of the first support 1, and a fifth gear 12 is located between the motor 14 and the first support 1. The other end of the motor 14 and the fifth gear 12 are abutted by a spring 13. The motor shaft of the motor 14 passes through the spring 13 and is sleeved with the fifth gear 12. The motor 14 can drive the fifth gear 12 to rotate through the motor shaft, and the latch 11 can push the fifth gear 12 to move along the motor shaft. Function: When the latch is locked, under the elastic support of the spring 13, the fifth gear is engaged with the first gear and the third gear. The motor 14 drives the fifth gear 12 to rotate through the motor shaft, and then uses the fifth gear 12 to drive the first gear, the second gear, the third gear, and the fourth gear to rotate, and finally drive the first roller shaft, the second roller shaft, the first coating shaft, and the second coating shaft to rotate. When the latch is unlocked, the latch 11 pushes the fifth gear 12 to move along the motor shaft. The fifth gear compresses the spring, and the fifth gear disengages from the first gear and the third gear, and finally the first roller shaft, the second roller shaft, the first coating shaft, and the second coating shaft rotate freely.

[0032] Specifically, the outer edge of the first bracket 1 has several protruding screw posts 101, and the edge of the motor 14 is screwed to the screw posts 101. A control mechanism 15 is located beside the motor 14, and the motor 14 is electrically connected to the control mechanism 15. The control mechanism 15 can control the forward and reverse rotation of the motor 14. Function: The screw connection facilitates the installation of the motor 14; and the control mechanism 15, by controlling the forward and reverse rotation of the motor 14 by a predetermined angle, facilitates the re-engagement of the fifth gear 12 with the first and third gears when the latch is locked. For example, for reference: the circuit diagram of the control mechanism controlling the forward rotation of the motor (i.e., the motor forward rotation drive circuit) can be found in [reference needed]. Figure 9 The circuit diagram for controlling the motor to reverse (i.e., the motor reverse drive circuit) can be found in [reference needed]. Figure 10 .

[0033] Specifically, the first support 1 and the second support 2 are distributed horizontally, the first roller 3 and the second roller 4 are distributed from top to bottom, and the first coating roller 5 and the second coating roller 6 are distributed from top to bottom; the first roller 3 and the second roller 4 are located behind the first coating roller 5 and the second coating roller 6, and the locking buckle 11 is located between the first roller 3 and the first coating roller 5. Function: The first coating roller 5 and the second coating roller 6 are used to heat and pressurize the film, so that the softened film is tightly bonded to the product to form a coated product, while the first roller 3 and the second roller 4 are used to carry the coated product from front to back.

[0034] Specifically, the latch 11 is rotatably connected to the inner side of the first bracket 1. The first bracket 1 is provided with a through hole 102 and a tension spring 16. One end of the latch 11 is connected to the tension spring 16, and the other end of the latch 11 passes through the through hole 102 and abuts against one end of the fifth gear 12. Function: By rotating the latch 11 downward, the latch can pass through the through hole 102 and push the fifth gear to move towards the spring, thereby unlocking the latch; while by rotating the latch 11 upward, under the elastic support of the spring 13, the fifth gear re-engages with the first gear and the third gear, thereby locking the latch. The tension of the tension spring 16 can maintain the latch in the locked state.

[0035] Specifically, the inner side of the first bracket 1 is provided with two protruding support plates 103, which are distributed front to back. Two through holes 102, also distributed front to back, are provided between the two support plates 103. A tension spring 16 is located above the space between the two support plates 103, and a latch 11 is located between the two support plates 103. The front and rear side walls of the latch 11 are rotatably connected to the two support plates 103, respectively. The top of the latch 11 is connected to the tension spring 16, and the bottom of the latch 11 is provided with two self-locking plates 1101. The two self-locking plates 1101 pass through the two through holes 102 and abut against one end of the fifth gear 12. Function: See [link / reference] Figure 1 , 5 When the latch is locked, it is in a vertical position, and the side walls of the two self-locking plates 1101 pass through the two through holes 102 and abut against one end of the fifth gear 12; see also Figure 2 When the latch is unlocked, the latch 11 is in a horizontal state. At this time, the bottom surfaces of the two self-locking plates 1101 pass through the two through holes 102 and abut against one end of the fifth gear 12, thus achieving self-locking. As long as the person manually moves the latch 11 upward, the self-locking state can be released, and it will be re-locked under the force of the tension spring 16 and the spring 13.

[0036] Specifically, the second gear 8 and the fourth gear 10 are located outside the second support 2, and heating tubes 17 are respectively provided inside the first coating shaft 5 and the second coating shaft 6; several annular protrusions 18 are provided on both the first roller shaft 3 and the second roller shaft 4, and annular grooves 19 are formed between adjacent annular protrusions 18. The annular protrusions 18 and annular grooves 19 on the first roller shaft 3 correspond one-to-one with the annular grooves 19 and annular protrusions 18 on the second roller shaft 4. Function: The heating tubes 17 enable the first coating shaft 5 and the second coating shaft 6 to have a heating function, while the annular grooves 19 and annular protrusions 18 can form an air channel between the first roller shaft 3 and the second roller shaft 4, which helps to reduce electrostatic adsorption.

[0037] Specifically, a base plate 20 is connected between the bottom ends of the first support 1 and the second support 2. A detection device 21 is provided on the base plate 20, and a rotating groove 2101 is provided on the detection device 21. The rotating groove 2101 is rotatably engaged with a rotating plate 2102. A torsion spring 2103 is connected between the rotating plate 2102 and the rotating groove 2101. The rotating plate 2102 is located between the first roller shaft 3, the second roller shaft 4, the first coating shaft 5, and the second coating shaft 6. Function: When a coated product passes through, the rotating plate 2102 of the detection device 21 rotates under the action of the coated product. When no coated product passes through, the rotating plate 2102 of the detection device 21 returns to its original position under the action of the torsion spring, thereby facilitating the determination of whether a coated product has passed through.

[0038] Specifically, the detection device 21 is also equipped with a detection slot 2104. A grating is installed inside the rotating slot 2101. The rotating plate 2102 can be downwardly engaged with the detection slot 2104, blocking the grating. The torsion spring 2103 can reset the rotating plate 2102 upwards. Function: When a laminated product passes through, the rotating plate 2102 of the detection device 21 rotates to the detection slot 2104 under the influence of the laminated product, blocking the grating. When no laminated product passes through, the rotating plate 2102 of the detection device 21 resets under the action of the torsion spring, and the rotating plate 2102 no longer blocks the grating, thus facilitating the determination of whether a laminated product has passed through.

[0039] Specifically, the laminating machine also includes a housing 22. A first support 1 and a second support 2 are disposed on the left and right sides inside the housing 22. A housing opening 2201 is located at the upper front of the housing 22, and a discharge port 2202 is located at the lower rear of the housing 22. A film feeding structure 23 is located above the space between the first support 1 and the second support 2. A transparent cover 24 is provided at the housing opening 2201, and a cutter assembly 25 is provided at the discharge port 2202. Functions: The film feeding structure 23 provides a thin film, which, together with the product fed in front, forms a laminated product. The transparent cover 24 provides protection, and the cutter assembly 25 cuts the laminated product exiting from the discharge port 2202.

[0040] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
