Description

Technical Field

[0001] The utility model relates to the technical field of glass tube conveying equipment, in particular to a conveying device for glass tubes. Background Art

[0002] In the field of lighting fixture processing, glass tubes are commonly used lamp tubes for lamps. After continuous forming, glass tubes need to be transferred to cutting equipment with the help of conveying equipment, cut into fixed lengths and quantities, and then the cut glass tubes are packaged or directly sent to the next process for processing. Existing glass tube conveying equipment commonly uses conveying rollers, which is simple and direct, and is suitable for conveying glass under normal circumstances.

[0003] For newly formed glass tubes, if the distance from the cutting equipment is short, there is not enough cooling time, and the existing conveying equipment does not have a cooling effect, the temperature of the glass tube is high, which causes inconvenience for subsequent processing (such as transportation, packaging, etc.); at the same time, during the transportation process, there will be more or less tube bursting, and glass fragments are difficult to clean up in the conveying equipment. Utility Model Content

[0004] The utility model aims to provide a conveying device for glass tubes, so as to solve the problems that the existing conveying equipment has no cooling effect and the glass fragments are difficult to clean in the conveying equipment.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A further technical solution is that the material guiding layer is lower than the air inlet end of the wind box.

[0008] A further technical solution is that a mesh cover covering the guide roller and the glass tube is rotatably installed on the top of the bellows.

[0009] A further technical solution is that the discharge port is communicated with the feed end of the weight hammer flap valve.

[0010] A further technical solution is: an air distribution groove parallel to the material guiding layer is arranged on the inner side of the wind box, and the air distribution groove is connected to an external air source.

[0011] A further technical solution is that the material guiding layer is a mesh cloth, the mesh cloth is higher than the air outlet end of the air distribution groove, and the air outlet of the air distribution groove is consistent with the length of the material guiding layer.

[0012] A further technical solution is that air guiding plates are symmetrically installed in the air outlet slit.

[0013] Compared with the prior art, at least one of the following beneficial effects can be achieved by the present utility model:

[0014] The present utility model provides a conveying device for glass tubes. This conveying device can rapidly cool down glass tubes at a relatively high temperature. During short-distance transportation, it can ensure that the temperature of the glass tubes is moderate, facilitating subsequent processing. At the same time, the air outlet slit on the air box can be used as a cleaning port for glass fragments after the glass tube bursts. The glass fragments fall onto the material guiding layer from the air outlet slit and are concentrated at the lower end of the material guiding layer, greatly facilitating the cleaning of the conveying device.

[0025] Embodiment 1:

[0026] As shown in this embodiment Figure 1 A conveying device for glass tubes includes a bracket 1, a bellows 2, guide rollers 3 and a material guiding layer 4. The bellows 2 is horizontally installed on the bracket 1 and its air inlet end is communicated with an external air source. The guide rollers 3 are linearly and evenly arranged and rotatably installed on the top of the bellows 2. An air outlet slit facing the guide rollers 3 is provided on the top of the bellows 2. The material guiding layer 4 is inclinedly installed in the bellows 2, and a discharge port is provided on one side of the bellows 2 close to the lower end of the material guiding layer 4.

[0027] After the glass tube 5 is formed, it is drawn onto the guide roller 3. At this time, an external air source (a wind supply device, such as a blower) starts to blow air into the air box 2, and an upward air flow is formed in the air outlet slit. Then, the advancing glass tube 5 is blown and cooled. If the glass tube 5 bursts during transportation, some of the glass fragments directly fall from the air outlet slit onto the material guiding layer 4, and the other part of the glass fragments on the air box 2 are swept onto the material guiding layer 4 through the air outlet slit by manual cleaning. Then, the glass fragments are uniformly concentrated at the lower end of the material guiding layer 4 for convenient discharge.

[0028] Preferably, the material guiding layer 4 is lower than the air inlet end of the air box 2.

[0029] Prevent the material guiding layer 4 from affecting the air outlet of the air box 2 towards the air outlet slit.

[0030] Preferably, a mesh cover 6 covering the guide roller 3 and the glass tube 5 is rotatably installed on the top of the air box 2.

[0031] The mesh cover 6 can reduce the risk of accidental damage to the glass tube 5, and at the same time does not affect the line of sight of personnel, facilitating the observation of the state of the glass tube 5.

[0032] Preferably, the discharge port is communicated with the feed end of the gravity flap valve 7.

[0033] The gravity flap valve 7 plays a role of locking air but not locking materials, does not affect the discharge of glass fragments, and can reduce the loss of air flow.

[0034] Preferably, an air distribution groove 8 parallel to the material guiding layer 4 is arranged inside the air box 2, and the air distribution groove 8 is communicated with the external air source.

[0035] The air distribution groove 8 can equalize the air flow, ensuring uniform and stable air flow inside the air box 2.

[0036] Embodiment 2:

[0037] On the basis of the above embodiment, in this embodiment, as Figure 2 shown, the material guiding layer 4 is a mesh cloth, the mesh cloth is higher than the air outlet end of the air distribution groove 8, and the air outlet of the air distribution groove 8 is consistent with the length of the material guiding layer 4.

[0038] The mesh cloth plays a role of ventilation and loading (glass fragments). On the basis of its inclined setting, in cooperation with the flow of air, it reaches a working state similar to that of an air conveying chute in existing material conveying equipment, discharging materials while blowing air, and blowing air can also improve the effect of material discharging.

[0039] Preferably, as Figure 3 shown, guide vanes 9 are symmetrically installed in the air outlet slit.

[0040] The guide vanes 9 can play a role of gathering air flow and enhancing the cooling effect.

[0041] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
