Description

Technical Field

[0001] The utility model relates to the field of glass tempering equipment, in particular to a hand-cranking device for glass tempering equipment. Background Art

[0002] Glass tempering equipment is used to temper glass. Generally, the glass is first heated to a certain temperature and then rapidly cooled so that the cooling rate of the glass surface is greater than the cooling rate of the glass inside, thereby forming tempered glass. The basic production process of glass tempering equipment is: loading → heating → cooling → unloading. The main drive is required to realize the transmission of glass at all stages. In the actual production process of glass tempering equipment, accidental glass breakage or power outages often occur. The remaining glass inside the equipment needs to be manually transported to the outside of the equipment. At this time, a hand-cranked device is often required to manually transport the remaining glass out.

[0003] The current hand-cranked structure often adopts a bevel gear transmission structure. Since the bevel gear is in a meshing state for a long time and rotates with the equipment transmission device, it causes serious gear wear, a sharp reduction in bearing service life, and increased repair and maintenance costs. At the same time, since the two gears run at high speed, they often generate louder noise, causing noise pollution. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a hand-cranked device for glass tempering equipment. By adopting a non-contact transmission mode of magnetic wheels, the wear of both is reduced. At the same time, the positioning slide groove and the knob plunger are used to realize the disengagement of the two magnetic wheels from each other during normal production. The bearing matching the active magnetic wheel is in a stationary state, which effectively extends the service life of the bearing and reduces noise pollution.

[0005] The technical solution adopted by the utility model is: a hand-cranked device for glass tempering equipment, comprising a transmission shaft, a passive magnetic wheel installed on the transmission shaft, a hand-cranked support located on the side of the transmission shaft, an active magnetic wheel rotatably installed on the hand-cranked support, and a hand-cranked assembly for driving the active magnetic wheel to rotate, the active magnetic wheel and the passive magnetic wheel are arranged orthogonally, a key slot is provided on the transmission shaft, the passive magnetic wheel is installed on the transmission shaft through a flat key, a knob plunger is provided on the passive magnetic wheel, a positioning slot is provided on the transmission shaft corresponding to the knob plunger, the passive magnetic wheel can move within the stroke range of the positioning slot to achieve engagement and disengagement of the active magnetic wheel and the passive magnetic wheel, and the front end of the knob plunger can be rotated out of the passive magnetic wheel and extended into the positioning slot on the transmission shaft to achieve axial positioning of the passive magnetic wheel.

[0006] Preferably, the hand crank assembly includes a bearing, a short shaft, and a crank handle. The short shaft is arranged inside the active magnetic wheel, and the bearing is installed inside the bearing seat of the short shaft. An inner hexagonal structure is provided at one end of the short shaft close to the crank handle, and an outer hexagonal structure is provided on the crank handle, which is installed in conjunction with the short shaft and is manually rotated by the crank handle.

[0007] Preferably, a first countersunk hole is provided on one side of the positioning slot and a second countersunk hole is provided on the other side. When the front end of the knob plunger is extended into the first countersunk hole, the position of the passive magnetic wheel is fixed and magnetic engagement with the active magnetic wheel is achieved. When the front end of the knob plunger is extended into the second countersunk hole, the position of the passive magnetic wheel is fixed and magnetic disengagement with the active magnetic wheel is achieved.

[0008] Preferably, the active magnetic wheel and the passive magnetic wheel are selected with corresponding numbers of magnetic poles to meet the requirements of different equipment for transmission speed ratio.

[0009] Preferably, the knob plunger is coupled to the passive magnetic wheel via a thread, and the front end of the knob plunger can be extended and retracted.

[0010] Preferably, the width of the positioning slot matches the front end of the knob plunger, and the length of the positioning slot can meet the engagement and disengagement of the two magnetic wheels.

[0011] Preferably, the active magnetic wheel and the passive magnetic wheel are arranged horizontally and orthogonally.

[0012] According to the above technical solution, the beneficial effects of the utility model are:

[0013] This hand-cranked device adopts a contactless magnetic transmission method, which effectively reduces the wear and tear of parts and reduces the cost of equipment maintenance.

DETAILED DESCRIPTION

[0018] The present invention is described in detail below by way of exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may also be beneficially combined in other embodiments.

[0019] It should be noted that: unless otherwise defined, the technical or scientific terms used herein shall have the usual meaning understood by persons having ordinary skills in the field to which the present invention belongs. The words "one", "an" or "the" and the like used in the specification and claims of the present utility model patent application do not express a quantity limitation, but rather indicate the presence of at least one. Words such as "include" or "comprise" indicate that the elements or objects appearing before "include" or "comprises" include the elements or objects listed after "include" or "comprises" and their equivalents, but do not exclude other elements or objects.

[0020] like Figure 1 As shown, a glass tempering machine with a hand-cranked mechanism employs a magnetic wheel drive, effectively reducing component wear and noise during transmission. The active magnetic wheel 3 is internally mounted with a short shaft 7, which is fitted with a bearing 6 mounted within the bearing seat of the short shaft 7. The hand-cranked support 2 can be rooted to the machine body or independently fixed to the ground. The rear end of the short shaft 7 is equipped with a hexagonal structure, which allows for manual rotation via a crank handle 8.

[0021] like Figure 2 The passive magnetic wheel 4 shown is installed on the transmission shaft 1, and a keyway is provided on the transmission shaft 1. A flat key 9 is provided in the keyway on the transmission shaft 1. The radial positioning of the passive magnetic wheel 4 is achieved by the flat key 9. At the same time, a knob plunger 5 is provided on the passive magnetic wheel 4. The front end of the knob plunger 5 can be retracted and extended, and a positioning groove 10 is provided at the corresponding position of the transmission shaft 1 and the knob plunger 5.

[0022] When the driven magnetic wheel 4 is moved to a position away from the active magnetic wheel 3, the front end of the knob plunger 5 extends to the second countersunk hole 10b, and the position of the passive magnetic wheel 4 is fixed and magnetically disengaged from the active magnetic wheel 3. By adjusting the distance between the passive magnetic wheel 4 and the active magnetic wheel 3, the engagement and disengagement of the two magnetic wheels are achieved, thereby realizing transmission output and transmission termination.

[0023] like Figure 1 、 Figure 2 、 Figure 3 As shown, the active magnetic wheel 3 and the passive magnetic wheel 4 are arranged orthogonally. When the passive magnetic wheel 4 moves to a position closer to the active magnetic wheel 3, the active magnetic wheel 3 and the passive magnetic wheel 4 are engaged under the action of the magnetic field, and the front end of the knob plunger 5 extends to the first countersunk hole 10a. The position of the passive magnetic wheel 4 is fixed. At this time, the active magnetic wheel 3 is rotated by the crank 8 to realize the rotational movement of the passive magnetic wheel 4, thereby realizing the rotation of the transmission shaft 1 and realizing functions such as emergency furnace discharge.

[0024] When the emergency is handled, the front end of the knob plunger 5 retracts, moving the passive magnetic wheel 4 to a position away from the active magnetic wheel 3. At this time, the active magnetic wheel 3 and the passive magnetic wheel 4 are disengaged, and the front end of the knob plunger 5 extends to the second countersunk hole 10b. The passive magnetic wheel 4 rotates with the transmission shaft 1, and the equipment resumes normal operation. The active magnetic wheel 3 is in a stationary state, which can effectively extend the service life of the bearing 6 on the short shaft 7 and reduce maintenance costs. At the same time, it effectively reduces the operating noise of the equipment and creates a better production environment.

[0025] The parts not described in detail in this embodiment are prior art;
