Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and in particular to a glass tube cutting device. Background Technology

[0002] In the glass tube processing and production process, glass tube cutting is one of the important steps. The traditional method of glass tube cutting is to place the glass tube on a conveyor for transport and then perform the cutting operation at the cutting station.

[0003] However, in practice, due to the lack of effective positioning and clamping methods, the glass tube is prone to axial tilting under the cutting force when the end is cut. Once the glass tube tilts axially, the cut ends will be uneven, severely affecting the processing accuracy and product quality. This substandard cutting effect not only increases the difficulty of subsequent processing steps but also wastes raw materials and increases production costs. Utility Model Content

[0004] This invention provides a glass tube cutting device to solve the problem that the ends of glass tubes cut by existing cutting devices are prone to tilting.

[0005] To alleviate the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] A glass tube cutting device includes a conveying mechanism and a positioning mechanism. The conveying mechanism includes a conveying frame, and the positioning mechanism includes two vertically symmetrically arranged positioning rollers. Semicircular grooves are formed on the side walls of the two positioning rollers. After the glass tube is transported by the conveying mechanism to the semicircular groove of the lower positioning roller, the upper and lower positioning rollers rotate synchronously in opposite directions to transfer the glass tube between the two positioning rollers, thereby clamping the glass tube.

[0007] Furthermore, a cutting mechanism is also connected to the conveying mechanism. The cutting mechanism includes a cutting disc, the axis of which is on the same vertical line as the axis of the positioning roller.

[0008] Furthermore, the cutting mechanism also includes a first motor connected to the conveyor frame, and the cutting disc is connected to the output end of the first motor.

[0009] Furthermore, a roller is rotatably connected to the inner wall of the semicircular groove. The axis of the roller is parallel to the axis of the glass tube, and the roller can roll relative to the glass tube.

[0010] Furthermore, the conveying mechanism also includes a lifting rod and a baffle. The lifting rod is disposed on the side of the conveying frame closer to the cutting mechanism, and the baffle is disposed on the side of the conveying frame away from the cutting mechanism.

[0011] Furthermore, the conveying mechanism also includes two conveyor chains symmetrically arranged on both sides of the conveyor frame, and multiple vertical rods arranged in a linear array are fixedly connected to each of the two conveyor chains, with the glass tube placed between two adjacent vertical rods.

[0012] Furthermore, it also includes a transmission mechanism, which includes a second motor and is connected to the two positioning rollers, with one of the positioning rollers connected to the second motor.

[0013] Furthermore, the transmission mechanism also includes a toothed gear connected to the output end of the second motor, a full-tooth gear rotatably connected to the conveyor frame, the toothed gear intermittently meshing with the full-tooth gear, and the full-tooth gear being drivenly connected to one of the positioning rollers.

[0014] Furthermore, the transmission mechanism also includes a positioning component, which includes a positioning disk fixedly connected to the end face of the full-tooth gear. The positioning disk has a positioning groove facing the same direction as the semi-circular groove. A positioning block is slidably connected to the conveyor frame. When the missing-tooth gear is not meshing with the full-tooth gear, the positioning block can engage with the positioning groove to lock the positioning roller.

[0015] Furthermore, a limiting frame is fixedly connected to the conveyor frame, a positioning rod is fixedly connected to the positioning block, the positioning rod is inserted into the limiting frame, a spring is sleeved on the positioning rod, and the two ends of the spring are fixedly connected to the limiting frame and the positioning block respectively.

[0016] The beneficial effects of this utility model are analyzed as follows:

[0017] A glass tube cutting device includes a conveying mechanism and a positioning mechanism. The conveying mechanism includes a conveying frame, and the positioning mechanism includes two vertically symmetrically arranged positioning rollers. Semicircular grooves are formed on the side walls of the two positioning rollers. After the glass tube is transported by the conveying mechanism to the semicircular groove of the lower positioning roller, the upper and lower positioning rollers rotate synchronously in opposite directions to transfer the glass tube between the two positioning rollers, thereby clamping the glass tube.

[0018] The glass tube is transported by a conveying mechanism for cutting. When the glass tube moves into the semi-circular groove on the positioning roller, the upper and lower positioning rollers rotate synchronously and in opposite directions, so that the glass tube is clamped by the upper and lower positioning rollers, ensuring that the glass tube will not slide axially. This ensures that when the end of the glass tube is cut, the cut end of the glass tube can be flush and will not tilt axially. Attached Figure Description

[0031] Examples, such as Figures 1-6 As shown, a glass tube cutting device includes a conveying mechanism 100 and a positioning mechanism 300. The conveying mechanism 100 includes a conveying frame 110, and the positioning mechanism 300 includes two vertically symmetrically arranged positioning rollers 310. Semicircular grooves 320 are formed on the side walls of the two positioning rollers 310. After the glass tube is transported by the conveying mechanism 100 to the semicircular groove 320 of the lower positioning roller 310, the upper and lower positioning rollers 310 rotate synchronously in opposite directions to transfer the glass tube between the two positioning rollers 310, thereby clamping the glass tube.

[0032] The working mechanism of the cutting device provided in this embodiment is as follows:

[0033] The glass tube is transported and cut via the conveyor mechanism 100. Figure 6 In this state, when the glass tube moves from left to right into the semi-circular groove 320 on the positioning roller 310, the upper positioning roller 310 rotates counterclockwise and the lower positioning roller 310 rotates clockwise, so that the glass tube is clamped by the upper and lower positioning rollers 310, ensuring that the glass tube will not slide axially. When the end of the glass tube is cut, the cut end of the glass tube can be flush and will not tilt axially.

[0034] Regarding the structure of the cutting mechanism 200, specifically:

[0035] The conveying mechanism 100 is also connected to a cutting mechanism 200, which includes a cutting disc 230. The axis of the cutting disc 230 and the axis of the positioning roller 310 are on the same vertical line.

[0036] The cutting disc 230 is mounted on the conveyor frame 110. When the glass tube is held and conveyed by two positioning rollers 310 to a position close to the center of the two positioning rollers 310, the cutting disc 230 can contact the glass tube and cut the glass tube.

[0037] Among the optional methods in this embodiment, the more preferred one is:

[0038] The cutting mechanism 200 also includes a first motor 220 connected to the conveyor frame 110, and a cutting disc 230 connected to the output end of the first motor 220.

[0039] The first motor 220 is fixedly connected to the conveyor frame 110 via the first base 210. When the first motor 220 is started, it can drive the cutting disc 230 to rotate.

[0040] Among the optional methods in this embodiment, the more preferred one is:

[0041] A roller 330 is rotatably connected to the inner wall of the semicircular groove 320. The axis of the roller 330 is parallel to the axis of the glass tube, and the roller 330 can roll relative to the glass tube.

[0042] When the cutting disc 230 comes into contact with the glass tube, the roller 330 is configured to allow the glass tube to rotate, thereby cutting the glass tube.

[0043] Regarding the structure of the conveying mechanism 100, specifically:

[0044] The conveying mechanism 100 also includes a lifting rod 150 and a baffle 140. The lifting rod 150 is disposed on the side of the conveying frame 110 close to the cutting mechanism 200, and the baffle 140 is disposed on the side of the conveying frame 110 away from the cutting mechanism 200.

[0045] When the conveying mechanism 100 transports the glass tube, one end of the glass tube can contact the top of the lifting rod 150. At this time, the glass tube can tilt, so that the tilted glass tube can slide towards the baffle 140, so that the position of the glass tube is corrected again. After the glass tube moves past the position of the lifting rod 150, it becomes horizontal and continues to move before being clamped and cut by two positioning rollers 310.

[0046] Among the optional methods in this embodiment, the more preferred one is:

[0047] The conveying mechanism 100 also includes two conveyor chains 120 symmetrically arranged on both sides of the conveyor frame 110. Multiple vertical rods 130 arranged in a linear array are fixedly connected to each of the two conveyor chains 120, and the glass tube is placed between two adjacent vertical rods 130.

[0048] The two conveyor chains 120 have the same conveying speed. Each conveyor chain 120 is equipped with multiple vertical rods 130. The vertical rods 130 on the two conveyor chains 120 are aligned one to one, so that the glass tube placed between the adjacent vertical rods 130 on the two conveyor chains 120 can be parallel to the axis of the cutting disc 230.

[0049] Regarding the structure of the transmission mechanism 400, specifically:

[0050] The transmission mechanism 400 includes a second motor 420 and two positioning rollers 310 that are connected to each other, with one of the positioning rollers 310 connected to the second motor 420.

[0051] The second motor 420 is used to drive the positioning roller 310 to rotate, and the speed of the second motor 420 is adjustable. By adjusting the speed of the second motor 420, the speed of the positioning roller 310 can be matched with the transmission speed of the conveyor chain 120.

[0052] Among the optional methods in this embodiment, the more preferred one is:

[0053] The transmission mechanism 400 also includes a toothed gear 430 connected to the output end of the second motor 420, and a full-tooth gear 440 rotatably connected to the conveyor frame 110. The toothed gear 430 and the full-tooth gear 440 intermittently mesh, and the full-tooth gear 440 is connected to one of the positioning rollers 310 in a transmission connection.

[0054] A first rotating seat 340 is fixedly connected inside the conveyor frame 110. A first rotating shaft 350 is connected to the middle of the lower positioning roller 310 and is rotatably connected to the first rotating seat 340. A second rotating shaft 360 is connected to the middle of the upper positioning roller 310. A third rotating shaft 364 is rotatably connected to the conveyor frame 110. A driven wheel 363 is fixedly connected to the end of the third rotating shaft 364. A driving wheel 361 is connected to the end of the second rotating shaft 360. A belt 362 drives the driving wheel 361 and the driven wheel 363. A transmission tooth 370 is fixedly connected to the end of the third rotating shaft 364 away from the driven wheel 363. A transmission tooth 370 is also connected to the end of the first rotating shaft 350. These two transmission teeth 370 mesh with each other, so that when the third rotating shaft 364 rotates, it drives the upper positioning roller 310. Figure 6 In this state, the lower positioning roller 310 rotates counterclockwise and clockwise, clamping the glass tube in the semi-circular groove 320. That is, at this time, the rotational tangent direction of the two positioning rollers 310 that are close to each other is consistent with the conveying direction of the glass tube.

[0055] The second motor 420 is connected to the conveyor frame 110 via the second base 410. When the second motor 420 is started, it can drive the toothed gear 430 to rotate. When the toothed gear 430 rotates and meshes with the full-tooth gear 440, it can drive the full-tooth gear 440 to rotate ninety degrees, so that the glass tube is conveyed to the middle of the two positioning rollers 310.

[0056] The positioning roller 310 stops after rotating 90 degrees. Four semi-circular grooves 320 are arranged in a ring on the side wall of the positioning roller 310. After each stop, the glass tube on the conveying mechanism 100 is at the same height as the axis of one of the horizontal semi-circular grooves 320 on the lower positioning roller 310. After the glass tube moves close to the lower semi-circular groove 320, the toothed gear 430 begins to mesh with the full-tooth gear 440. Simultaneously, the conveyor chain 120 runs, and the full-tooth gear 440 drives the third rotating shaft 364 to rotate. The third rotating shaft 364 is driven by the transmission gear 370. The lower positioning roller 310 rotates, and the semi-circular groove 320 lifts the glass tube and moves it upward between the two vertical rods 130. Since the conveyor chain 120 is in a moving state at this time, the glass tube can also move upward while moving laterally. The upper positioning roller 310 rotates in the opposite direction to the lower one. After both positioning rollers 310 have rotated 90 degrees, they can clamp the glass tube. After both positioning rollers 310 have rotated 90 degrees, the toothed gear 430 no longer meshes with the full-toothed gear 440. At this time, the conveyor chain 120 stops running, and the cutting mechanism cuts the glass tube.

[0057] The motors driving the conveyor chain 120 and the second motor 420 are both controlled by a PLC program.

[0058] Among the optional methods in this embodiment, the more preferred one is:

[0059] The transmission mechanism 400 also includes a positioning component, which includes a positioning disk 450 fixedly connected to the end face of the full-tooth gear 440. The positioning disk 450 has a positioning groove 451 facing the same direction as the semi-circular groove 320. A positioning block 460 is slidably connected to the conveyor frame 110. When the toothed gear 430 is not meshing with the full-tooth gear 440, the positioning block 460 can be engaged with the positioning groove 451 to lock the positioning roller 310.

[0060] The positioning component is designed so that when the missing tooth gear 430 is not engaged with the full tooth gear 440, the positioning roller 310 can maintain its position. When the full tooth gear 440 rotates ninety degrees, the positioning block 460 is inserted into the positioning groove 451 on the positioning disk 450, making it difficult for the full tooth gear 440 to rotate, thereby locking the position of the positioning roller 310. When the positioning roller 310 is locked, the glass tube is cut. Each of the two positioning rollers 310 has four semi-circular grooves 320. The positioning roller 310 rotates ninety degrees each time to continuously clamp and fix the glass tube.

[0061] Among the optional methods in this embodiment, the more preferred one is:

[0062] A limit frame 462 is fixedly connected to the conveyor frame 110, and a positioning rod 461 is fixedly connected to the positioning block 460. The positioning rod 461 is inserted into the limit frame 462, and a spring 463 is sleeved on the positioning rod 461. The two ends of the spring 463 are fixedly connected to the limit frame 462 and the positioning block 460 respectively.

[0063] Spring 463 provides a thrust to positioning block 460, enabling positioning block 460 to slide toward positioning disk 450, ensuring that positioning block 460 can apply sufficient locking force to positioning disk 450. When full gear 440 is driven to rotate, it can push positioning block 460 to overcome the elastic force of spring 463 and slide, ensuring that the rotation of full gear 440 is not interfered with.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
