Description

Technical Field

[0001] The utility model relates to the technical field of calendering, in particular to a calendering machine for glass production. Background Art

[0002] Photovoltaic ultra-white glass is a special glass material used in photovoltaic power generation modules. It has high light transmittance and low reflection characteristics, which can effectively improve the photoelectric conversion efficiency of photovoltaic power generation modules. In the production process of photovoltaic ultra-white glass, in order to ensure uniformity and surface smoothness, it is usually necessary to use a calender to evenly calender it into a flat glass sheet.

[0003] A Chinese patent with authorization announcement number CN218465682U discloses a calendering roller for photovoltaic glass calendering equipment. Through the coordinated use of a rotating shaft, a driven shaft and a blowing fan blade, when the calendering roller body rotates, the blowing fan blade can be rotated under the action of a driving gear and a driven gear, thereby generating a certain wind force and blowing toward the calendering roller body, accelerating the heat dissipation on the surface of the calendering roller body, preventing adhesion between the glass and the calendering roller body, and improving the practicality of the device.

[0004] However, the calender mentioned above dissipates heat from one end of the calender roller surface, and its heat dissipation uniformity is poor. The temperature at the end close to the fan blade is lower, and the temperature at the end far from the fan blade is higher, which affects the calendering effect. Utility Model Content

[0005] In view of the problems existing in the background technology, a calender for glass production is proposed. An air cooling mechanism is provided to cooperate with a driving mechanism, and a transverse pipe is provided on the side of two calendering rollers which are away from each other, so that cold air can be drawn from the cold air box during the calendering process and sprayed evenly on the surface of the calendering roller, thereby improving the uniformity of cooling. Moreover, the air extraction component cooperates with the driving mechanism, and no additional power parts are needed to draw cold air from the cold air box, thereby reducing the electricity cost during use and improving its practicality.

[0023] Embodiment 1

[0024] As Figures 1 - 3 shown, a calender for glass production proposed by the present utility model includes a bottom plate 1, a driving mechanism and a wind cooling mechanism. Two groups of vertical plates 2 are symmetrically arranged on the bottom plate 1. Two groups of rotating shafts 3 are rotatably arranged between the two groups of vertical plates 2. Calender rolls 4 for calendering glass are arranged on the two groups of rotating shafts 3. The driving mechanism is arranged on the vertical plates 2 and is used to drive the two groups of calender rolls 4 to rotate synchronously and in opposite directions. The wind cooling mechanism cooperates with the driving mechanism to perform wind cooling on the two groups of calender rolls 4 from the upper and lower directions respectively.

[0025] As Figure 1 shown, the driving mechanism includes a motor 5 and a gear disc 6. The motor 5 is installed outside the corresponding vertical plate 2, and its output end is connected to the corresponding rotating shaft 3. Two groups of gear discs 6 are provided, respectively located at the ends of the two groups of rotating shafts 3 away from the motor 5. The two groups of gear discs 6 are meshed with each other. By driving one rotating shaft 3 to rotate through the motor 5, the gear disc 6 at the end of the rotating shaft 3 rotates, and the other gear disc 6 is meshed with the gear disc 6, thereby driving the other rotating shaft 3 to rotate synchronously and in opposite directions, so as to perform calendering operation on the glass located between the two calender rolls 4.

[0026] Embodiment 2

[0027] As Figures 1 - 3 shown, a calender for glass production proposed by the present utility model, on the basis of the above embodiment, this embodiment also details the specific components of the wind cooling mechanism and its cooperation mode with the driving mechanism.

[0028] As Figure 1As shown, the air cooling mechanism includes a cold air box 7, an air charging pipe 8, an air cylinder 9, an air outlet pipe 10, a transverse pipe 11 and an exhaust assembly. The cold air box 7 is arranged on the bottom plate 1 at a side corresponding to the vertical plate 2, and an air cylinder 9 is arranged between the cold air box 7 and the vertical plate 2, and an exhaust assembly is arranged in the air cylinder 9; the bottom of the air cylinder 9 is connected to the air charging pipe 8, and the air charging pipe 8 is connected to the cold air box 7, and the side of the air cylinder 9 is connected to the air outlet pipe 10 passing through the vertical plate 2, and a transverse pipe 11 is arranged at one end of the air outlet pipe 10, and a plurality of groups of nozzles 12 facing the calendering roller 4 are linearly and equidistantly connected on the transverse pipe 11.

[0029] like Figure 3 As shown, both the inflation pipe 8 and the outlet pipe 10 are provided with a one-way valve 13 for preventing the air flow from retreating.

[0030] like Figure 3 As shown, the exhaust assembly includes a piston plate 14, a piston rod 15 and a connecting rod 16. The piston plate 14 is slidably arranged on the inner side of the air cylinder 9, and is connected to the piston rod 15 that passes through the air cylinder 9. The top end of the piston rod 15 is rotatably connected to one end of the connecting rod 16, and the other end of the connecting rod 16 is rotatably connected to the eccentric part of the gear disc 6. The gear disc 6 is driven to rotate by the motor 5. During the rotation of the gear disc 6, the piston rod 15 and the piston plate 14 are driven to reciprocate and rise and fall through the connecting rod 16, so that the air cylinder 9 reciprocally extracts cold air from the cold air box 7 through the inflation pipe 8.

[0031] like Figure 1 As shown, two groups of transverse tubes 11 are provided, which are respectively arranged between the two vertical plates 2 and on the sides of the two groups of calendering rollers 4 facing away from each other.

[0032] In summary, when the utility model is in use, by starting the motor 5, the motor 5 cooperates with the rotating shaft 3 and the toothed disc 6 to drive the two calendering rollers 4 to rotate in opposite directions, so as to transport and calender the glass between the two calendering rollers 4. During the calendering process, the two sets of toothed discs 6 are in a continuous rotation process, which drives the two sets of piston rods 15 and piston plates 14 to reciprocate and rise and fall in the air cylinder 9 through the connecting rod 16, and performs piston movement. During the movement, the air cylinder 9 draws cold air from the cold air box 7 through the inflation pipe 8, and discharges it into the cross pipe 11 through the outlet pipe 10, and finally sprays it evenly through the nozzle 12 on the cross pipe 11, so as to dissipate the heat on the surface of the calendering roller 4, thereby improving the uniformity of the heat dissipation of the calendering roller 4 as a whole, and does not need to add additional power parts to draw cold air from the cold air box 7, thereby reducing the electricity cost during use and improving its practicality.

[0033] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
