Description

Technical Field

[0001] The utility model relates to the field of glass tube processing auxiliary equipment, in particular to a glass tube feeding guide alignment device. Background Art

[0002] In lamp manufacturing factories, glass tubes are components that hold filaments and need to be mass-produced. In the process of glass tube production, after the glass tubes are cut, they need to be moved to the next process. After the horizontally arranged glass tubes are cut and placed on the feeding part of the feed belt, a guiding alignment device is required to ensure that the ends of the glass tubes are aligned when they enter the feed belt for transmission. Common alignment devices use two baffles arranged in a V shape, and use the abutment between the ends of the glass tubes and the baffles during the movement, so that under the guiding action of the baffles, the ends of the glass tubes enter the equidistant conveying channel. In this way, the ends of the two adjacent glass tubes passing through the two baffles can be aligned and conveyed downward under the action of the feed belt.

[0003] However, in the existing baffle-type guide alignment device, the glass tube will move relative to the baffle during its movement, which will inevitably cause some glass tubes to tilt due to the friction between the two, and the glass tube cannot move along its axis under the action of the baffle. When the glass tube tilts, it cannot align the two ends of the adjacent glass tubes after passing through the two baffles, which affects the subsequent processing of the glass tube on the feeding belt. Utility Model Content

[0004] The utility model aims to provide a glass tube feeding guide alignment device to solve the problem that the existing V-shaped guide alignment device is prone to axis deviation due to friction between the end of the glass tube and the baffle.

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

[0006] A glass tube feeding guide alignment device comprises a pair of guide platforms, the two guide platforms are arranged in a V shape, and the shortest distance between the two guide platforms is the same as the length of the guided glass tube;

[0007] The guide platform comprises a vertically arranged active roller and a driven roller parallel to the axis of the active roller, and the outer walls of the active roller and the driven roller are connected by a soft rubber sleeve;

[0008] The sides of the soft rubber sleeves in the two guide platforms facing each other serve as guide surfaces contacting the end of the glass tube. The sides of the two soft rubber sleeves facing each other are arranged in a V shape. The moving direction of the side of the soft rubber sleeve facing the glass tube is the same as the moving direction of the glass tube.

[0009] Preferably, the guide platform comprises a mounting plate, a rotating motor is mounted on the bottom surface of the mounting plate, a rotating end of the rotating motor passes through the mounting plate to coaxially mount the active roller, and the driven roller is rotatably mounted on the top surface of the mounting plate.

[0010] Furthermore, the roller bodies of the active roller and the driven roller are coaxially provided with a clearance groove, and the clearance groove is arranged at a position which is located at the same horizontal plane as the end of the glass tube.

[0011] Furthermore, the active roller includes a first rotating shaft coaxially connected to the rotating end of the rotating motor, and a first disc and a second disc are coaxially provided on the first rotating shaft. The first disc and the second disc are respectively fitted with the inner wall of the soft rubber sleeve, and the first disc and the second disc are between the first disc and the second disc.

[0012] Furthermore, the driven roller includes a second shaft arranged on the mounting plate, on which a third disc and a fourth disc are coaxially mounted for rotation, respectively, the third disc and the fourth disc are respectively fitted with the inner wall of the soft rubber sleeve, and the clearance groove is between the third disc and the fourth disc.

[0013] Furthermore, a vertically penetrating sliding channel is constructed on the mounting plate, and an extension direction of the sliding channel is parallel to a connecting direction of the active roller and the driven roller. The second shaft is slidably arranged in the sliding channel, and an externally threaded rod parallel to its extension direction is rotatably arranged in the sliding channel, the externally threaded rod penetrates the second shaft and extends out of the sliding channel, the second shaft is threadedly connected to the externally threaded rod, and the externally threaded rod is rotatably connected to the mounting plate via a bearing sleeve.

[0014] During use, the utility model has the following beneficial effects:

[0015] A pair of guide tables are used to guide and align the glass tube passing through. When the guide tables are used for guiding and aligning, the active roller is always in a rotating state, and then under the tightening effect of the driven wheel on the soft rubber sleeve, the soft rubber sleeve is also in a moving state, so that the moving speed of the soft rubber sleeve is the same as the moving speed of the end of the glass tube. In this way, when the guide tables are used for guiding, the soft rubber sleeve abuts against the end of the glass tube, and in the process of the glass tube moving, the soft rubber sleeve and the glass tube are in a relatively static state and move together. In this way, as the glass tube moves, the glass tube can only receive thrust along the axis direction of the glass tube under the action of the two guide tables arranged in a V shape, so that the glass tube keeps the axis parallel and moves continuously along the axis. After the glass tube passes through the two guide tables, the adjacent two glass tubes can also always be in a state of being parallel to each other and aligned at both ends. It effectively avoids the existing baffle-type alignment device, in which after the glass tube passes through the baffle, some glass tubes have an axis offset, resulting in the situation that the adjacent two glass tubes cannot be parallel and the two ends cannot be aligned.

[0026] Please refer to Figures 1 to 3 As shown, a glass tube feeding guide alignment device comprises a pair of guide platforms 100, the two guide platforms 100 are arranged in a V shape, and the shortest distance between the two guide platforms 100 is the same as the length of the guided glass tube;

[0027] The guide platform 100 comprises a vertically arranged active roller 1 and a driven roller 2 parallel to the axis of the active roller 1, and the outer walls of the active roller 1 and the driven roller 2 are connected by a soft rubber sleeve 3;

[0028] The surfaces of the soft rubber sleeves 3 in the two guide platforms 100 facing each other serve as guide surfaces in contact with the end of the glass tube. The surfaces of the two soft rubber sleeves 3 facing each other are arranged in a V shape. The moving direction of the surface of the soft rubber sleeves 3 facing the glass tube is the same as the moving direction of the glass tube.

[0029] In this way, a pair of guide platforms 100 are used to guide and align the glass tube passing through. When the guide platforms 100 are used for guiding and aligning, the active roller 1 is always in a rotating state, and then under the tightening effect of the driven wheel on the soft rubber sleeve 3, the soft rubber sleeve 3 is also in a moving state, so that the moving speed of the soft rubber sleeve 3 is the same as the moving speed of the end of the glass tube. In this way, when the guide platforms 100 are used for guiding, the soft rubber sleeve 3 abuts against the end of the glass tube, and in the process of the movement of the glass tube, the soft rubber sleeve 3 and the glass tube are in a relatively static state and move together. In this way, as the glass tube moves, the glass tube can only receive a thrust along the axis direction of the glass tube under the action of the two guide platforms 100 arranged in a V shape, so that the glass tube keeps the axis parallel and continuously moves along the axis. After the glass tube passes through the two guide platforms 100, the two adjacent glass tubes can also always be in a state of being parallel to each other and aligned at both ends. The method effectively avoids the situation that the existing baffle-type alignment device causes the axis of some glass tubes to deviate after the glass tubes pass through the baffle, resulting in the situation that two adjacent glass tubes cannot be parallel and the two ends cannot be aligned.

[0030] Specifically, for the guide platform 100, the guide platform 100 includes a mounting plate 4, a rotating motor 5 is installed on the bottom surface of the mounting plate 4, the rotating end of the rotating motor 5 passes through the mounting plate 4 to coaxially install the active roller 1, and the driven roller 2 is rotatably installed on the top surface of the mounting plate 4.

[0031] The mounting plates 4 can be fixedly mounted on the bracket, so that the two mounting plates 4 are arranged at a position close to the feeding part of the conveyor belt, so that the glass tubes entering the conveyor belt can be stably guided and aligned.

[0032] Furthermore, in order to avoid hard contact between the end of the glass tube and the soft rubber sleeve 3, the roller bodies of the active roller 1 and the driven roller 2 are coaxially configured with a clearance groove 6, and the clearance groove 6 is arranged at a position on the same horizontal plane as the end of the glass tube.

[0033] In this way, by utilizing the setting of the give way groove 6, when the end of the glass tube contacts the soft rubber sleeve 3, the soft rubber sleeve 3 can be completely deformed under the give way effect of the give way groove 6, effectively avoiding the roller wall of the active roller 1 or the driven roller 2 from blocking the deformation of the soft rubber sleeve 3, thereby affecting the deformation buffering effect of the soft rubber sleeve 3 when contacting the end of the glass tube.

[0034] Specifically, the active roller 1 includes a first rotating shaft 7 coaxially connected to the rotating end of the rotating motor 5, and a first disc 8 and a second disc 9 are coaxially provided on the first rotating shaft 7. The first disc 8 and the second disc 9 are respectively fitted with the inner wall of the soft rubber sleeve 3, and the first disc 8 and the second disc 9 are between the first disc 8 and the second disc 9. The clearance groove 6 is.

[0035] At the same time, the driven roller 2 includes a second shaft 10 arranged on the mounting plate 4, and a third disc 11 and a fourth disc 12 are coaxially mounted on the second shaft 10, and the third disc 11 and the fourth disc 12 are respectively fitted with the inner wall of the soft rubber sleeve 3, and the clearance groove 6 is between the third disc 11 and the fourth disc 12.

[0036] Furthermore, in order to conveniently adjust the distance between the active roller 1 and the driven roller 2, thereby adjusting the tension of the soft rubber sleeve 3, and thereby adjusting the deformation of the soft rubber sleeve 3 when it contacts the end of the glass tube and during the alignment and limiting process, a vertically penetrating sliding channel 13 is constructed on the mounting plate 4, and the extension direction of the sliding channel 13 is parallel to the connecting direction of the active roller 1 and the driven roller 2. The second shaft 10 is slidably arranged in the sliding channel 13, and an externally threaded rod 14 parallel to its extension direction is rotatably arranged in the sliding channel 13, the externally threaded rod 14 penetrates the second shaft 10 and extends out of the sliding channel 13, the second shaft 10 is threadedly connected to the externally threaded rod 14, and the externally threaded rod 14 is rotatably connected to the mounting plate 4 through a bearing sleeve.

[0037] In this way, by rotating the external threaded rod 14 , the distance between the second rod and the first rotating shaft 7 is adjusted, thereby adjusting the distance between the active roller 1 and the driven roller 2 .

[0038] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
