Description

Technical Field

[0001] The utility model relates to the technical field of glass production and processing, in particular to an air-suspended graphite wheel mechanism. Background Art

[0002] In the glass manufacturing process, the support and guidance of high-temperature glass tubes usually rely on power-driven graphite wheels. The existing graphite wheel is equipped with a fan blade at one end of the double-headed wheel. The air pump sprays air by tilting the fan blade to push the double-headed wheel to rotate synchronously along the direction of the glass tube. This design causes the double-headed wheel to bear unilateral force for a long time during operation, which causes the horizontal angle deviation from the conveying direction when the glass tube is conveyed, affecting the molding quality. At the same time, it also leads to accelerated consumption of wear parts, which not only reduces the durability of the components, but also affects the service life and performance of the entire device.

[0035] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0036] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0038] The existing graphite wheel mechanism has technical problems of horizontal angle deviation and aggravated wear caused by unilateral driving force.

[0039] In view of this, the utility model provides an air-suspended graphite wheel mechanism, comprising:

[0040] The graphite wheel 100 and the support shaft 200 inserted in the graphite wheel 100. The graphite wheel 100 is rotatably connected to the support shaft 200, the support shaft 200 is horizontally arranged and has air holes 201 with an opening direction vertically upward on the side wall, and the air holes 201 are symmetrically arranged about the middle section of the graphite wheel 100. The airflow ejected from the air holes 201 is used to provide lift and rotational torque to the graphite wheel 100 to transport the glass tube.

[0041] Based on the above technical solutions, the air-suspended graphite wheel mechanism provided by the utility model can achieve the following technical effects:

[0042] The air suspension graphite wheel mechanism provides lift and rotational torque by spraying air upwards on the inner wall of the central hole of the graphite wheel 100. The lift is used to offset the load of the glass tube and the graphite wheel 100 to achieve suspension, and the rotational torque is used to drive the graphite wheel 100 to rotate. The air holes 201 are symmetrically arranged about the middle section of the graphite wheel 100, and there is no horizontal eccentric load problem. The suspension state reduces wear. The technical problems of horizontal angle deviation and aggravated wear caused by unilateral driving force in the existing graphite wheel mechanism are overcome.

[0043] The following combination Figures 1 to 6 The structure and shape of the air-suspended graphite wheel mechanism provided in this embodiment are described in detail:

[0044] In the solution of this embodiment, the air suspension graphite wheel mechanism also includes a flow control valve 400 and a flow meter. Figure 2 As shown, the support shaft 200 is configured as a hollow shaft, one end of which is blocked and the other end is open. The flow control valve 400 is installed at the open end of the support shaft 200 and is connected to the air pump to drive the graphite wheel 100 to transport the glass tube. Among them, the graphite wheel 100 is configured as a V-shaped wheel symmetrical on both sides, and the V-shaped depression is used to match the glass tube. The flow meter is installed on the flow control valve 400, which is used to detect the gas flow through the support shaft 200 to control the flow and air pressure, and then accurately control the air flow lift of the air pump to achieve the suspension of the graphite wheel 100. The airflow passes through the support shaft 200, the air hole 201 and the inner hole of the graphite wheel 100 in turn, and is finally discharged from the end face of the graphite wheel 100. The discharged airflow takes away the heat of the air suspension graphite wheel mechanism, avoiding the support shaft 200 from expanding due to high temperature and the stuck phenomenon between the fixed sleeve 300 and the graphite wheel 100, and also reduces the erosion of the graphite wheel 100 due to high temperature.

[0045] In the optional solution of this embodiment, Figure 5 As shown, the axis of the air hole 201 does not intersect with the axis of the support shaft 200 and is parallel to the middle section. At this time, the airflow ejected from the air hole 201 impacts upward on one side of the inner wall of the graphite wheel 100. Because the point of action of this force is not at the center of mass of the graphite wheel 100, a rotational torque is formed to drive the graphite wheel 100 to complete the transportation of the glass tube.

[0046] Furthermore, Figure 3 As shown, the air hole 201 is provided with an exhaust groove 202 on the outer wall of the support shaft 200. The airflow discharged from the exhaust groove 202 is used to apply a rotational torque in the same direction as the conveying direction of the glass tube to the graphite wheel 100. The jet airflow is ejected through the exhaust groove 202, and the friction and momentum transfer between the airflow and the graphite wheel 100 further enhance the rotational power of the graphite wheel 100.

[0047] In the optional solution of this embodiment, Figure 4 As shown, the axis of the air hole 201 intersects with the axis of the support shaft 200 and is parallel to the mid-section. The air hole 201 is provided with an exhaust groove 202 on the outer wall of the support shaft 200. The airflow discharged from the exhaust groove 202 is used to apply a rotational torque in the same direction as the conveying direction of the glass tube to the graphite wheel 100, so as to drive the graphite wheel 100 to complete the conveying of the glass tube.

[0048] In order to ensure the uniform force on the graphite wheel 100, in the solution of this embodiment, a plurality of air holes 201 are arranged along the length direction of the graphite wheel 100 and are evenly distributed within the length range of the graphite wheel 100. The graphite wheel 100 is driven at the same time to avoid horizontal unbalanced loading of the graphite wheel 100 due to uneven force.

[0049] In order to prevent the graphite wheel 100 from running off track, in the solution of this embodiment, Figure 1 As shown, the air suspension graphite wheel mechanism also includes a fixing sleeve 300, which includes a first limiting ring 310, a second limiting ring 320 and a top screw which are sleeved on the support shaft 200. The first limiting ring 310 and the second limiting ring 320 are respectively arranged at both ends of the graphite wheel 100, and are both fixedly connected to the support shaft 200 through the top screw.

[0050] In order to further increase the rotation speed of the graphite wheel 100, in the solution of this embodiment, as Figure 6 As shown, the first limiting ring 310 is provided with a plurality of air guide grooves 301 evenly distributed in a ring around its axis at one end close to the graphite wheel 100. Each air guide groove 301 is used to guide the airflow ejected between the graphite wheel 100 and the first limiting ring 310, so as to apply a rotational torque in the same direction as the conveying direction of the glass tube to the graphite wheel 100. In the process of the airflow entering the air guide groove 301 and being quickly discharged along the air guide groove 301, the airflow acts on the end face of the graphite wheel 100 through friction and momentum transfer to generate a rotational torque, thereby enhancing the rotational power of the graphite wheel 100.

[0051] Specifically, the second limiting ring 320 and the first limiting ring 310 are mirror images of each other and are symmetrically arranged at both ends of the graphite wheel 100. The two end faces of the graphite wheel 100 are simultaneously subjected to the rotational torque brought by the airflow, balancing the force and avoiding horizontal unbalanced loading of the graphite wheel 100.

[0052] In the solution of this embodiment, Figure 6 As shown, each air guide groove 301 is not connected to the inner hole of the first limiting ring 310, so a complete annular structure is left in the central area of ​​the first limiting ring 310, thereby achieving a flow limiting effect between the inner wall of the graphite wheel 100 and the external environment, avoiding excessive gas loss that causes a decrease in lift and makes it impossible to achieve a suspended state of the graphite wheel 100.

[0053] In summary, the specific working process of the air-suspended graphite wheel mechanism provided in this embodiment is as follows:

[0054] The first limiting ring 310 is provided with a side of the air guide groove 301 facing the graphite wheel 100, and the rotation direction of the air guide groove 301 is consistent with the exhaust groove 202. The first limiting ring 310 and the second limiting ring 320 are symmetrically distributed at both ends of the graphite wheel 100. The first limiting ring 310, the graphite wheel 100 and the second limiting ring 320 are sequentially inserted into the support shaft 200, and the position of the graphite wheel 100 is adjusted so that all the air holes 201 are symmetrically distributed about the middle section of the graphite wheel 100. The first limiting ring 310 and the second limiting ring 320 are fixedly connected to the support shaft 200 with a top screw to limit the graphite wheel 100. The support shaft 200 is installed on the production line, and the open end of the support shaft 200 is connected to the air pump through the flow control valve 400 and the flow meter.

[0055] The airflow provided by the air pump is sprayed on the inner wall of the graphite wheel 100 through the air hole 201 to generate lift. The airflow flows along the inner wall of the graphite wheel 100. The airflow acts on the inner wall of the center hole of the graphite wheel 100 through friction and momentum transfer to generate a rotational torque. The airflow enters the air guide groove 301 through the gap between the first limiting ring 310, the second limiting ring 320 and the graphite wheel 100. While the airflow is discharged outward along the air guide groove 301, it acts on the end face of the graphite wheel 100 through friction and momentum transfer, thereby generating a rotational torque. The lift provided is used to offset the load of the graphite wheel 100 and the glass tube, and the rotational torque is used to drive the graphite wheel 100 to rotate synchronously with the glass tube. The discharged airflow takes away the heat of the air-suspended graphite wheel mechanism, avoiding the expansion of the support shaft 200 due to high temperature and the jamming between the fixed sleeve 300 and the graphite wheel 100, and also reduces the erosion of the graphite wheel 100 by high temperature.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
