[0027] like Figure 1-Figure 3 As shown, a borosilicate glass tube cutting device comprises:

[0028] A base 1 is horizontally arranged on the ground, and a first shaft connection block 11 and a second shaft connection block 12 are fixedly connected to the front and rear sides of the inner side of the base 1 in a mirror-symmetrical manner;

[0029] A connecting rod driving mechanism 13, which is arranged on the first shaft connection block 11 and the second shaft connection block 12;

[0030] A cutting blade 14, which is transmission-connected to the connecting rod driving mechanism 13;

[0031] An electric clamp 15, fixedly connected to the connecting rod driving mechanism 13;

[0032] A motor frame plate 16 is fixedly connected to one side of the base 1, and a driving motor 17 is fixedly connected to the motor frame plate 16, and a main shaft of the driving motor 17 is drivingly connected to the connecting rod driving mechanism 13;

[0033] The approach driving mechanism 18 is disposed on both sides of the base 1 and is transmission-connected to the connecting rod driving mechanism 13 .

[0034] In this embodiment, the borosilicate glass tube is clamped by the electric clamp 15, and the main shaft of the driving motor 17 is rotated to drive the connecting rod driving mechanism 13, which in turn drives the cutting blade 14 and the electric clamp 15 to rotate, and then the borosilicate glass tube is cut. The distance between the cutting blade 14 and the borosilicate glass tube is changed by the approaching driving mechanism 18, thereby controlling the feed amount.

[0035] As an optional implementation, Figure 1 , 2 As shown in 3, a borosilicate glass tube cutting device according to claim 1 is characterized in that the connecting rod driving structure includes a first connecting rod frame 19 rotatably connected to the first shaft connection block 11 on one side at the top side, and a second connecting rod frame 2 is rotatably connected to the second shaft connection block 12 on one side, the first connecting rod frame includes a first rotating shaft 21 rotatably connected to the first shaft connection block 11, and the first rotating shaft 21 is rotatably connected to connecting rods A22 and B23 on both sides, and a second rotating shaft 24 is rotatably connected between the connecting rods A22 and B23, and the second connecting rod frame 2 includes a third rotating shaft 25 rotatably connected to the second shaft connection block 12, and the third rotating shaft 25 is rotatably connected to connecting rods C26 and D27 on both sides, and a fourth rotating shaft 28 is rotatably connected between the connecting rods C26 and D27, and the connecting rods B23 are rotatably connected to connecting rods E29, and the connecting rods D27 are rotatably connected to connecting rods F30, and the connecting rods E29 and F30 are hinged;

[0036] Thus, when the connecting rod D27 and the connecting rod B23 rotate, the relative distance between them will change.

[0037] As an optional implementation, Figure 1 , 2As shown in , 3, the third rotating shaft 25 is transmission-connected with the main shaft of the driving motor 17, the third rotating shaft 25 is fixedly connected with a first gear 31, the connecting rod C26 is rotationally connected with a second gear 32, the second gear 32 is meshed with the first gear 31, the fourth rotating shaft 28 is fixedly connected with a third gear 33, the third gear 33 is meshed with the second gear 32, the connecting rod F30 is rotationally connected with a fourth gear 34, the fourth gear 34 is meshed with the third gear 33, the connecting rod E29 is rotationally connected with a fifth gear 35, the fifth gear 35 is meshed with the fourth gear 34, the connecting rod F30 is also rotationally connected with a first pulley 36, the first pulley 36 is transmission-connected with the fifth gear 35, the other end of the connecting rod F30 is rotationally connected with a second pulley 37, and a transmission belt 38 is transmission-connected between the second pulley 37 and the first pulley 36;

[0038] In this way, when the connecting rod D27 and the connecting rod B23 rotate, the relative distance between the two will change, and the angle between the connecting rod E29 and the connecting rod F30 will also change, but the first gear 31, the second gear 32, and the third gear 33 can still maintain meshing, so that the third gear 33 drives the first pulley 36 to rotate, and the first pulley 36 drives the second pulley 37 to rotate, so that when the approaching driving mechanism 18 changes the distance between the cutting blade 14 and the borosilicate glass tube, the rotation of the second pulley 37 and the third gear 33 can still be guaranteed.

[0039] As an optional implementation, Figure 1 , 2 As shown in 3, a one-way bearing 39 is provided at the center of the second pulley 37, a connecting shaft 41 is transmission-connected to the one-way bearing 39, and an electric clamp 15 is fixedly connected to the connecting shaft 41;

[0040] In this way, the device has two states, one is that the electric clamp 15 and the third gear 33 rotate together to perform circular cutting on the borosilicate glass tube, and the other is that the third gear 33 rotates and the electric clamp 15 does not rotate, so the borosilicate glass is straight cut. It is suitable for borosilicate glass tubes of different specifications and models, such as special-shaped glass tubes or thinner glass tubes are suitable for straight cutting, and thicker glass tubes are suitable for circular cutting.

[0041] As an optional implementation, Figure 1 , 2As shown in , 3, the approach drive mechanism 18 includes a first support shaft 42 whose one end is rotatably connected to the second shaft connection block 12 on the other side, the other end of the first support shaft 42 is fixedly connected to the connecting rod D27, a first support swing rod 43 is fixedly connected to the first support shaft 42, a drive shaft 44 is rotatably connected to the first support swing rod 43, the other end of the drive shaft 44 is transmission-connected to the fourth rotating shaft 28, the cutting blade 14 is detachably connected to the drive shaft 44, the approach drive mechanism 18 also includes a second support shaft 46 whose one end is rotatably connected to the first shaft connection block 11 on the other side, the other end of the second support shaft 46 is fixedly connected to the connecting rod B23, and a second support swing rod 47 is fixedly connected to the second support shaft 46;

[0042] In this way, the first support shaft 42 and the first support swing rod 43 support the drive shaft 44 and the approach drive mechanism 18 , and the second support shaft 46 and the second support swing rod 47 support the approach drive mechanism 18 .

[0043] As an optional implementation, Figure 1 , 2 As shown in FIG. 3 , the approach drive mechanism 18 also includes fixed rods 48 fixedly connected to the two ends of the base 1 in a mirror-image manner, and the middle of each fixed rod 48 is rotatably connected to a telescopic cylinder 49, and the telescopic end of each telescopic cylinder 49 is rotatably connected to a crank 5, and the two ends of the crank 5 on the front side are respectively fixedly connected to the bottom end of the connecting rod B23 and the bottom of the first supporting swing rod 43, and the two ends of the crank 5 on the rear side are respectively fixedly connected to the bottom end of the connecting rod D27 and the bottom of the second supporting swing rod 47;

[0044] In this way, the extension and retraction of the two telescopic cylinders 49 will respectively pull the two cranks 5 to move, thereby changing the distance between the cutting blade 14 and the electric clamping jaw 15 .

[0045] As an optional implementation, Figure 1 , 2 As shown in 3, the base 1 has rounded edges;

[0046] This prevents sharp edges from causing harm to workers.

[0047] Those skilled in the art should understand that the discussion of any of the above embodiments is only exemplary and is not intended to imply that the scope of the present invention is limited to these examples; under the concept of the present invention, the technical features in the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other changes in different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.
