Description

Technical Field

[0001] The utility model relates to a transmission device of a laminating machine. Background Art

[0002] The laminator is mainly composed of transmission device, heating temperature control system, operation control panel, rubber roller and other components. The transmission device is an important part of the laminator. The transmission device of the traditional laminator includes: a driving gear driven by a motor, two rubber rollers and a roller shaft gear matched with the driving gear. When the laminator is working, the motor drives the driving gear, and the driving gear drives the roller shaft gear to make the two rubber rollers rotate relative to each other. However, during the operation of the laminator, due to problems with the laminating material itself or other external reasons, the laminating material may be stuck in the rubber roller of the laminator. At this time, if the laminating material is forcibly pulled out, it may cause damage to the laminating material. Moreover, since the driving gear is connected to the motor shaft and is relatively fixed in position with the roller shaft gear, the laminating material cannot be withdrawn by reversing the rubber roller. At this time, the method of removing the material is troublesome and time-consuming, which will lead to the problem of reduced production efficiency of the laminator. Utility Model Content

[0003] The utility model provides a transmission device for a laminator.

[0004] The technical solution adopted by the utility model to solve the above technical problems is:

[0005] A laminator transmission device comprises two rubber roller shafts arranged adjacent to each other and brackets arranged on both sides of the rubber roller shafts, two roller shaft gears are arranged on the outer side of one end of the bracket, the two roller shaft gears are respectively fixed to the upper and lower rubber roller shafts, and the two roller shaft gears are meshed with each other; a driving gear is meshed on the roller shaft gear on the lower side, a through hole and a first gear are arranged at the center of the driving gear, a clutch button is matched with the first gear, the clutch button comprises a connecting hole, a second gear and a button part, the connecting hole is arranged at the top of the clutch button, the second gear is arranged on the outer wall of the clutch button, the second gear is meshed with the first gear, so that the clutch button is meshed inside the driving gear, and the button part is exposed outside the bottom end of the driving gear through the through hole of the driving gear; a spring is arranged on the upper end of the second gear of the clutch button, the spring is sleeved on the outer wall of the upper end of the second gear of the clutch button, the upper end of the spring abuts against the inner side of the motor, and the lower end abuts against the upper end of the second gear, the spring is in a compressed state, the motor is provided with a driving shaft, and the driving shaft passes through the spring and matches the connecting hole.

[0006] Preferably, the connecting hole is D-shaped.

[0007] Preferably, the drive shaft is arranged at the inner bottom of the motor, and the drive shaft is D-shaped.

[0008] Compared with the prior art, the transmission device of the laminator of the utility model is provided with a clutch button for internal meshing of the driving gear. In normal state, the tension of the spring forces the clutch button to mesh with the driving gear. When the plastic material is stuck, the clutch button can be pressed to separate from the driving gear, and the driving gear no longer rotates, so that the rubber roller shaft of the laminator stops rotating, and the stuck material can be taken out at this time. The setting of the clutch button improves the flexibility of the transmission device, and the driving gear is disengaged from the driving shaft. The roller shaft gear can be reversed by pulling the plastic material to pull it out of the rubber roller, thereby improving the use efficiency of the laminator and the user experience.

[0010] Figure 2 The utility model is an exploded schematic diagram of a transmission device of a laminating machine. DETAILED DESCRIPTION

[0011] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0012] like Figure 1 to Figure 2 As shown, a laminator transmission device includes two rubber roller shafts 1 arranged adjacent to each other in the upper and lower directions and a bracket 2 arranged on both sides of the rubber roller shaft 1, two roller shaft gears 3 are arranged on the outer side of one end of the bracket 2, and the two roller shaft gears 3 are respectively fixed to the upper and lower rubber roller shafts 1, and the two roller shaft gears 3 are meshed with each other.

[0013] A driving gear 4 is meshed on the roller gear 3 on the lower side. A through hole 41 and a first gear 42 are provided at the center of the driving gear 4. A clutch button 5 is provided at the first gear 42. The clutch button 5 includes a connecting hole 51, a second gear 52 and a button portion 53. The connecting hole 51 is provided at the top of the clutch button 5. The connecting hole 51 is D-shaped. The second gear 52 is provided on the outer wall of the clutch button 5. The second gear 52 is meshed with the first gear 42, so that the clutch button 5 is meshed inside the driving gear 4. The button portion 53 is exposed outside the bottom end of the driving gear 4 through the through hole 41 of the driving gear 4.

[0014] A spring 6 is provided at the upper end of the second gear 52 of the clutch button 5. The spring 6 is sleeved on the outer wall of the upper end of the second gear 52 of the clutch button 5. The upper end of the spring 6 abuts against the inner side of the motor 7. The spring 6 is in a compressed state, forcing the second gear 52 to always engage with the first gear 42, so that the clutch button 5 is always engaged with the driving gear 4. A driving shaft 71 is provided at the bottom of the motor 7. The driving shaft 71 is D-shaped. The driving shaft 71 passes through the spring 6 and cooperates with the connecting hole 51, so that the motor 7 can drive the clutch button 5 to move, so that the clutch button 5 can drive the driving gear 4 and the roller gear 3 to move.

[0015] When using the laminator, if the laminating material is stuck, the clutch button 5 can be pressed to compress the spring 6 again to separate the first gear 42 and the second gear 52, so that the clutch button 5 leaves the driving gear 4, the driving gear 4 no longer rotates, and the rubber roller shaft 1 of the laminator stops rotating. At this time, the stuck material can be taken out.

[0016] The transmission device of the laminator of the present invention is provided with a clutch button 5 for internal meshing of the driving gear 4. In normal state, the tension of the spring 6 forces the clutch button 5 to mesh with the driving gear 4. When the plastic material is stuck, the clutch button 5 can be pressed to separate from the driving gear 4, and the driving gear 4 no longer rotates, so that the rubber roller shaft 1 of the laminator stops rotating, and the stuck material can be taken out. The provision of the clutch button 5 improves the flexibility of the transmission device, and the driving gear 4 is disengaged from the driving shaft 71. The roller shaft gear 3 can be reversed by pulling the plastic material to be pulled out of the rubber roller, thereby improving the use efficiency of the laminator and the user experience.

[0017] Finally, it should be noted that the above embodiments only illustrate the technical solutions of the present invention, rather than limiting it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
