Description

Technical Field

[0001] This utility model relates to the field of glass bottle annealing technology, and in particular to a glass bottle annealing apparatus. Background Technology

[0002] Annealing improves the mechanical strength and thermal stability of glass bottles by heating the glass above its strain point and then slowly cooling it, causing the internal structure to reorganize and eliminating or significantly reducing these stresses. Therefore, an existing glass bottle annealing device, publication number CN222809358U, adjusts the spacing between several first and second limiting rods according to the width of the glass bottle. During adjustment, a slider slides within a groove. After the lateral positions of the first and second limiting rods on the transmission belt are adjusted, the first limiting ring threaded to the side of the hollow threaded column is tightened to fix the position of the slider. The spacing between the first and second limiting rods is adjusted according to the height of the glass bottle by rotating an adjusting screw. The rotation of the adjusting screw drives the first limiting rod to move along the adjusting screw. After the positions of several first and second limiting rods are adjusted, the second limiting ring is tightened to fix the position of the adjusting screw. Using an existing automatic feeding device, several glass bottles are neatly placed between adjacent first and second limiting rods, and the transmission belt is started to transport the glass bottles. The heating device in the annealing chamber is turned on to anneal the glass bottles on the transmission belt.

[0003] However, when the glass bottle is conveyed at a constant speed by the conveyor belt, the bottle body rubs against the first and second limit rods, generating resistance at the contact point that is opposite to the direction of transport. Because glass bottles are small in size and light in weight, this local resistance can easily disrupt their force balance, causing the bottle body to deflect or tilt. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a glass bottle annealing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a glass bottle annealing device, including an operating table and an annealing box set at the center of the table surface. A belt conveyor passing through the annealing box is embedded in the operating table surface. Mounting frames are fixedly installed at both ends of the operating table surface, and several pairs of bevel gear shafts are set on the operating table. Each pair of bevel gear shafts is respectively set on two mounting frames, and a connecting strip that is clearance-fitted with the operating table surface is fixedly installed on the shaft of each pair of bevel gear shafts. From top to bottom, upper sprockets and lower sprockets are respectively arranged coaxially, with the upper sprockets sleeved on the bevel gear shafts and the lower sprockets fixedly installed on the bevel gear shafts. A chain passing through the annealing box is meshed between the two upper sprockets and two lower sprockets of each pair of bevel gear shafts.

[0006] Preferably, the top of the lower sprocket extends upward and passes through the upper sprocket on the same bevel gear shaft, and the top of the lower sprocket is also rotatably connected to a screw, the screw thread passing through the upper sprocket on the same bevel gear shaft.

[0007] Preferably, the extension at the top of the lower sprocket and the screw are both arranged parallel to the bevel gear shaft, and an auxiliary sprocket is fixedly installed on the surface of the screw near the bottom end. A chain is also meshed between the two auxiliary sprockets of each pair of bevel gear shafts.

[0008] Preferably, the chain between the two auxiliary sprockets is located in the middle of the chain between the two lower sprockets.

[0009] Preferably, the top edge of the mounting bracket is provided with a sliding groove, and each bevel gear shaft is rotatably connected to a slider that is slidably connected to the sliding groove. The upper surface of the slider extends outward and the extension is damped by bolts with the top edge of the mounting bracket.

[0010] Preferably, the gear end of the bevel gear shaft is located above the mounting bracket, and a lead screw is rotatably connected to the top edge of the mounting bracket. A keyway is provided on the surface of the lead screw, and a bevel gear ring is connected to the gear end of each bevel gear shaft via the keyway on the surface of the lead screw. The bevel gear ring meshes with the gear end of the adjacent bevel gear shaft, and a nut that is threadedly connected to the lead screw is provided on the other side of the bevel gear ring.

[0011] Preferably, a gearbox is fixedly mounted on the mounting bracket, the output shaft of the gearbox passes through the surface of the mounting bracket and is fixedly connected to one end of the lead screw, and a synchronous pulley is fixedly mounted on the input shaft of the gearbox.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, by setting up a belt conveyor, an upper sprocket, and a lower sprocket, the belt conveyor lifts the bottom of the glass bottle, and two chains clamp the body of the glass bottle. All three move at the same speed, driving the glass bottle to move. The belt lifts the bottom of the bottle and the chains on both sides clamp the body of the bottle at the same speed. There is no relative slippage between the glass bottle and the belt and chains, eliminating the root cause of the reverse resistance generated by the friction between the limiting rod and the bottle body, ensuring the bottle body is under balanced force, and preventing the bottle body from deflecting or tilting.

[0013] 2. In this utility model, only one screw needs to be rotated to drive the other screw to rotate through the synchronous transmission of the auxiliary sprocket, so as to realize the synchronous lifting and lowering of the two upper sprockets on the same pair of bevel gear shafts, ensuring that the clamping height of the chains on both sides is consistent and avoiding the bottle body tilting due to asymmetrical clamping height; the extension of the lower sprocket provides guidance to ensure that the upper sprockets lift and lower smoothly and have high clamping accuracy.

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] like Figures 1-4As shown, the glass bottle annealing device includes an operating table 1 and an annealing box 2 located at the center of the table. The structure of the annealing box 2 in this embodiment is similar to that of existing glass heating furnaces, such as the glass bottle annealing furnace disclosed in patent CN219585981U. The improvement of this solution lies in ensuring the smooth movement of the glass bottle. A belt conveyor 3 is embedded in the operating table 1, passing through the annealing box 2. The glass bottle is placed on the belt conveyor 3, which then moves it to the annealing box 2 for annealing. The belt conveyor 3 is a metal mesh belt, as is known in the prior art. Mounting frames 5 are fixedly installed at both ends of the operating table 1, and several pairs of bevel gear shafts 8 are provided on the operating table 1. Each pair of bevel gear shafts 8 is respectively mounted on two mounting frames 5, and a connecting strip 19 with a clearance fit to the operating table 1 is fixedly installed on the shaft of each pair of bevel gear shafts 8. The connecting strip 19 ensures that the corresponding pair of bevel gear shafts 8 can slide synchronously, thus facilitating the movement of the glass bottle according to its movement. The size of the bottle is adjusted by the spacing between two adjacent pairs of bevel gear shafts 8. From top to bottom, the bevel gear shaft 8 has coaxially distributed upper sprockets 11 and lower sprockets 9, with the upper sprockets 11 sleeved on the bevel gear shaft 8 and the lower sprockets 9 fixedly mounted on it. A chain 16 passing through the annealing chamber 2 is meshed between the two upper sprockets 11 and two lower sprockets 9 of each pair of bevel gear shafts 8. In actual use, the upper sprockets 11 and lower sprockets on the same bevel gear shaft 8 are adjusted according to the height of the glass bottle. The spacing of 9 is used, and the chain 16 between the two upper sprockets 11 and lower sprockets 9 of each pair of bevel gear shafts 8 is used to clamp and fit the glass bottle body. By controlling the rotation speed of the bevel gear shaft 8 to be consistent with the moving speed of the belt conveyor 3, the belt part of the belt conveyor 3 and the chain 16 between the upper sprockets 11 and lower sprockets 9 can be moved synchronously, so that the glass bottle moves while the bottom and body of the bottle are clamped at the same time, avoiding relative sliding between the glass bottle body and the chain 16 and the resulting friction and resistance.

[0019] The top of the lower sprocket 9 extends upward and passes through the upper sprocket 11 on the same bevel gear shaft 8. The top of the lower sprocket 9 is also rotatably connected to a screw 10, and the screw 10 is threaded through the upper sprocket 11 on the same bevel gear shaft 8. The extension of the top of the lower sprocket 9 and the screw 10 are both set parallel to the bevel gear shaft 8, and an auxiliary sprocket 12 is fixedly installed on the surface of the screw 10 near the bottom. A chain 16 is also meshed between the two auxiliary sprockets 12 of each pair of bevel gear shafts 8. The chain 16 between the two auxiliary sprockets 12 is located in the middle of the chain 16 between the two lower sprockets 9. The chain 16 between the auxiliary sprockets 12 can ensure that the two auxiliary sprockets 12 of each pair of bevel gear shafts 8 rotate at the same speed. Therefore, in actual use, only one screw 10 needs to be rotated, and the corresponding other screw 10 will rotate synchronously. Under the guiding and assisting action of the extension of the top of the same lower sprocket 9, the upper sprocket 11 of the same bevel gear shaft 8 can be raised and lowered, thereby realizing the synchronous raising and lowering of the two upper sprockets 11 of the same pair of bevel gear shafts 8.

[0020] The top edge of the mounting bracket 5 has a groove 6. Each bevel gear shaft 8 is rotatably connected to a slider 17 that is slidably connected to the groove 6. The upper surface of the slider 17 extends outward and the extension is damped by bolts to the top edge of the mounting bracket 5. Under normal circumstances, the position of the slider 17 can be fixed by threading bolts on the slider 17 and tightening the bolts to make the bolts press against the surface of the mounting bracket 5. When it is necessary to adjust the distance between two adjacent pairs of bevel gear shafts 8, simply rotate the bolts in the opposite direction to loosen them, so that the slider 17 can slide in the groove 6, thereby adjusting the position of the bevel gear shaft 8 in the groove 6 and adjusting the distance between two adjacent pairs of bevel gear shafts 8.

[0021] The gear end of the bevel gear shaft 8 is located above the mounting bracket 5. The top edge of the mounting bracket 5 is rotatably connected to the lead screw 7. The surface of the lead screw 7 is provided with a keyway 13, and the surface of the lead screw 7 is connected to the gear end of each bevel gear shaft 8 via the keyway 13. The bevel gear ring 15 is meshed with the gear end of the adjacent bevel gear shaft 8, and the other side of the bevel gear ring 15 is fitted with a nut 14 that is threadedly connected to the lead screw 7. In use, the position of the slider 17 is adjusted according to the position. By rotating the nut 14, the adjacent bevel gear ring 15 is pushed to slide along the keyway 13 until it meshes with the corresponding gear end of the bevel gear shaft 8. By continuously rotating the nut 14 to press the bevel gear ring 15, the lead screw 7 can rotate to drive the nut 14 to rotate. Under the action of the keyway 13, the bevel gear ring 15 can rotate, thereby realizing the rotation of the meshed bevel gear shaft 8. In addition, the nut 14 used in this solution can be a pre-existing anti-loosening nut. A gearbox 18 is fixedly mounted on the mounting frame 5. The output shaft of the gearbox 18 passes through the surface of the mounting frame 5 and is fixedly connected to one end of the lead screw 7. A synchronous pulley 4 is fixedly mounted on the input shaft of the gearbox 18. The belts at both ends of the belt conveyor 3 are respectively set close to the two mounting frames 5. One end of the belt rollers at both ends of the belt conveyor 3 passes through the surface of the operating table 1 and is also mounted with a synchronous pulley 4. A synchronous belt is set between the two synchronous pulleys 4 on the same side of the operating table 1. The synchronous pulleys 4 and synchronous belts used in this solution can be replaced by sprockets and chains 16 in the existing known technology. In actual use, the synchronous pulleys 4 and synchronous belts are used to transmit the power of the belt rollers of the belt conveyor 3 to the input shaft of the gearbox 18. After the speed is adjusted by the gearbox 18, the power is transmitted to the drive lead screw 7 through the output shaft to rotate, thereby realizing the rotation of the bevel gear shaft 8. Furthermore, by adjusting the speed of the gearbox 18, it can be ensured that the belt conveyor 3 that lifts the bottom of the glass bottle and the chain 16 that clamps the body of the glass bottle move at the same speed. Additionally, the chains 16 on both sides of the glass bottle need to be set in the same direction of movement. Therefore, in actual use, in combination with... Figure 1The installation position of the bevel gear ring 15 can be adjusted, that is, the bevel gear ring 15 located on both sides of the glass bottle is located in the middle position of the two bevel gear shafts 8 on both sides of the glass bottle, that is, the nuts 14 and the bevel gear ring 15 on both sides of the glass bottle are symmetrically distributed about the glass bottle.

[0022] The method of using this utility model is as follows: Adjust the spacing between adjacent bevel gear shafts 8 according to the size of the glass bottle. Specifically: rotate the bolt on the slider 17 in the reverse direction to separate the bolt from the surface of the mounting bracket 5, thereby releasing the slider 17 from the groove 6 of the mounting bracket 5; slide the slider 17 along the groove 6 to drive the bevel gear shafts 8 to move synchronously, and adjust the spacing between the two adjacent pairs of bevel gear shafts 8 to match the diameter of the glass bottle; after the spacing adjustment is completed, tighten the bolt in the forward direction, and fix the position of the slider 17 and the bevel gear shafts 8 by the damping cooperation between the bolt and the surface of the mounting bracket 5.

[0023] Adjust the distance between the upper and lower sprockets 9 according to the height of the glass bottle. Specifically: rotate the screw 10 on any bevel gear shaft 8. Since the two auxiliary sprockets 12 of each pair of bevel gear shafts 8 are engaged synchronously through the chain 16, the other screw 10 will rotate synchronously as well. Under the guidance of the upper sprocket 11 and the extension at the top of the lower sprocket 9, the rotation of the screw 10 drives the upper sprocket 11 to rise and fall along the bevel gear shaft 8, so as to realize the synchronous rise and fall of the two upper sprockets 11 of the same pair of bevel gear shafts 8. Adjust the chain 16 between the upper and lower sprockets 9 to be aligned with the middle of the glass bottle body or a suitable height, so as to ensure that the chain 16 can clamp and fit the bottle body.

[0024] Adjust the meshing state of the bevel gear ring 15 and the bevel gear shaft 8. Specifically: rotate the nut 14 on the lead screw 7 to push the bevel gear ring 15 to slide along the keyway 13 of the lead screw 7, so that the bevel gear ring 15 is fully meshed with the corresponding gear end of the bevel gear shaft 8; continue to tighten the nut 14 to press and fix the bevel gear ring 15, ensuring that the lead screw 7 can drive the bevel gear shaft 8 to rotate synchronously through the bevel gear ring 15 when rotating.

[0025] Synchronous speed regulation and start-up are as follows: Start the belt conveyor 3, and the synchronous pulley 4 at one end of its belt roller transmits power to the input shaft of the gearbox 18 through the synchronous belt; After the gearbox 18 adjusts the speed according to the process requirements, it drives the lead screw 7 to rotate through the output shaft. The lead screw 7 drives the bevel gear ring 15 and the meshing bevel gear shaft 8 to rotate, so that the chain 16 between the upper and lower sprockets 9 moves at the same speed as the belt of the belt conveyor 3; Place the glass bottle on the belt of the belt conveyor 3, the belt lifts the bottom of the bottle, and the chains 16 on both sides clamp the bottle body. All three move at the same speed to smoothly enter the annealing box 2 for annealing operation.

[0026] The wiring diagrams of the annealing box 2, belt conveyor 3, and gearbox 18 in this utility model are common knowledge in the field. Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the annealing box 2, belt conveyor 3, and gearbox 18 will not be explained in detail.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
