Technical Field

[0001] The utility model relates to the technical field related to glass processing equipment, in particular to a lifting transmission mechanism for a paper laying machine. Background Art

[0002] Flat glass is easily scratched during transportation and storage, or the glass surface may become moldy when exposed to moisture and heat. Laying paper between the glass surfaces is a packaging method widely used by most glass manufacturers to prevent glass scratches, mold, and a series of other problems.

[0003] The paper feeding device is mainly used for the paper feeding roller motor to drive the paper feeding roller to transport paper outwards, and the traction component pulls the paper to realize the stacking and paper laying process more quickly. The paper feeding device needs to be lifted and lowered in conjunction with the screw lifter. The screw lifter is composed of a worm gear reducer and a screw. Its reduction component is a worm transmission, which uses the worm to drive the worm wheel to achieve reduction. The worm wheel is equivalent to the nut of the lifting screw and matches the lifting screw. The lifting speed of the screw lifter is equal to the worm input speed divided by the reduction ratio of the worm gear and worm, and then multiplied by the pitch of the screw. The cylindrical gear reducer, due to its structure, this type of screw lifter is generally lubricated with grease. The maintenance and maintenance of the screw lifter are usually performed manually. Therefore, during long-term operation, the staff needs to frequently stop the machine to add lubricating oil to the worm gear, which will not only affect the operating efficiency, but also increase the labor intensity of the staff.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-4 The utility model provides a technical solution: a lifting transmission mechanism of a paper laying machine, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a lifting transmission base plate 2 is fixed on the top of the paper laying machine frame 1, and a transmission shaft 3 is arranged above the lifting transmission base plate 2, and commutators 6 are arranged at both ends of the top of the lifting transmission base plate 2. A driving mechanism 7 is also arranged on the lifting transmission base plate 2, and the driving mechanism 7 is used to drive the transmission shaft 3 to rotate;

[0028] The driving mechanism 7 includes a driving mechanism frame 701, a rotating shaft 703 is arranged inside the mechanism frame 701, and a worm 704 is sleeved on the rotating shaft 703, a worm wheel 705 is also arranged inside the driving mechanism frame 701, the transmission shaft 3 passes through the driving mechanism frame 701, the worm wheel 705 is sleeved on the transmission shaft 3, and the worm wheel 705 is meshed and connected with the worm 704;

[0029] A self-lubricating mechanism 8 is also provided inside the driving mechanism frame 701 .

[0030] Specifically, a flat keyway is provided in the middle of the transmission shaft 3, the worm gear 705 is sleeved on the flat keyway, flat keyways are provided at both ends of the transmission shaft 3, and the plum blossom coupling 5 is separately sleeved on the transmission shaft 3 and the commutator 6.

[0031] The lifting transmission base plate 2 is welded with square plates on both sides, and the bottom of the square plate is provided with a circular hole for installing the commutator 6, and the square plate has four through holes for connecting and fixing the commutator 6 on both sides.

[0032] The commutator 6 is a right-angle commutator, and a group of vertical bevel gears and a group of horizontal bevel gears are arranged inside the right-angle commutator. The vertical bevel gears are connected to the plum blossom coupling 5, and the horizontal bevel gears are connected to the lead screws at both ends of the side walls of the paper laying machine frame 1. A nut is arranged on the lead screw, and the nut is connected to the equipment below the paper laying machine frame 1.

[0033] The lifting transmission mechanism in the prior art usually adopts a reduction motor plus a synchronous belt drive. This method is firstly troublesome to install, as the synchronous belt needs to be passed through the lifting transmission shaft in advance. Secondly, it is not so easy to adjust the tension. After installing the reduction motor, we can only tighten it by adjusting the position of the reduction motor mounting hole and tightening or resisting it with bolts. The lifting transmission shaft may be too tight, causing deformation of the middle part of the lifting transmission shaft, and it will jump during movement. After a long time, the reduction motor will shift and the transmission will be unstable. Thirdly, the motor may become loose due to long-term vibration operation, resulting in unstable transmission of the synchronous belt drive.

[0034] This technical solution can greatly avoid this situation, the installation becomes simpler, and the workers waste less time adjusting the motor position, thereby increasing production efficiency.

[0038] like Figure 4 As shown, the self-lubricating mechanism 8 includes an oil delivery pipe 801, an auger 802 is installed inside the oil delivery pipe 801, a pulley 803 is installed on the top of the oil delivery pipe 801, and the pulley 803 is connected to the auger 802, a pulley 804 is sleeved on the rotating shaft 703, and the pulley 804 is connected to the pulley 803, an oil inlet is opened at the bottom of the oil delivery pipe 801, and an oil outlet pipe is fixed to the top of the oil delivery pipe 801.

[0039] like Figure 4 As shown, a guide plate 805 is also fixed inside the driving mechanism frame 701 , and the guide plate 805 is located above the worm gear 705 .

[0040] Working principle: the lubricating oil can be introduced into the driving mechanism frame 701 in advance. When in use, the servo motor 702 can be turned on to drive the rotating shaft 703 and the worm 704 to rotate. The worm 704 will drive the worm wheel 705 and the transmission shaft 3 on the bearing seat 4 to rotate, and the transmission shaft 3 will transmit the torque to the commutator 6 through the plum blossom coupling 5. The commutator 6 will drive the lead screws at both ends of the side wall of the paper laying machine frame 1 to rotate, thereby driving the nut and the equipment below the paper laying machine frame 1 to be lifted or lowered through the rotation of the lead screw. During the rotation of the rotating shaft 703, it will also drive the pulley 2 804 to rotate, and the pulley 2 804 will drive the pulley 1 803 to rotate through the belt, and the pulley 1 803 will drive the auger 802, and the auger 802 will transport the lubricating oil at the bottom of the driving mechanism frame 701 to the oil outlet pipe at the top of the oil delivery pipe 801 for discharge, and then the lubricating oil will flow through the guide plate 805 to between the worm 704 and the worm wheel 705 for lubrication.
