Description

Technical Field

[0001] This utility model belongs to the field of pharmaceutical glass tube manufacturing technology, and more specifically, relates to a precision cutting mechanism for borosilicate brown pharmaceutical glass tubes. Background Technology

[0002] Currently, the production of pharmaceutical glass tubes typically involves heating the glass tube with a flame nozzle after it has been formed, then cutting it using a rounding machine. The cut glass tubes fall directly into a receiving box for collection, and are then segmented for use in the production of pharmaceutical glass tubes and other similar products.

[0003] For example, a pharmaceutical glass tube end-cutting device, as disclosed in patent publication number CN222250472U, includes a cutting table. A push block and a limiting plate are slidably fitted within the cutting table. Multiple first clamping blocks are rotatably fitted on the push block, and multiple second clamping blocks are rotatably fitted on the limiting plate. A pharmaceutical glass tube is placed between the first and second clamping blocks. A fixing plate and a cutting plate are installed within the cutting table. A blade is fixed to one side of the fixing plate, and a feeding port is opened on one side of the cutting table. In this invention, the first clamping blocks are rotatably mounted on the push block, and the second clamping blocks are rotatably mounted on the limiting plate. These first and second clamping blocks can fix the pharmaceutical glass tube and allow it to rotate, thereby cutting the circumference of the pharmaceutical glass tube, improving the cutting effect of the end face. Furthermore, the position of the limiting plate can be adjusted, thereby adjusting the cutting position of the pharmaceutical glass tube and expanding the applicability of the device.

[0004] However, the aforementioned pharmaceutical glass tube end cutting device may cause tiny glass fragments to splash into the inside of the glass tube after cutting, affecting the purity of the subsequently filled medicine. Utility Model Content

Figure 1-3 A precision cutting mechanism for borosilicate brown medicine glass tubes includes a base plate 10; the upper end of the base plate 10 is fixedly connected to slide rail 11 and slide rail 2 12 from left to right; two supports 14 are respectively provided on the base plate 10; the right support 14 is fixedly connected to a motor 15; the output end of the motor 15 is fixedly connected to a lead screw 17; the lead screw 17 is rotatably connected to both supports 14; a cutting device is also included, which is threadedly connected to the lead screw 17; the lower end of the cutting device extends between slide rail 11 and slide rail 2 12; the cutting device is provided with a suction pipe 2 that can absorb debris from the upper end of slide rail 11. 5; The suction pipe 25 is fixedly connected to the extraction pipe 21 at its rear side; The lower end of the extraction pipe 21 is fixedly connected to the extraction pump 20; The first slide 11 is an inclined slide; The left end of the second slide 12 is an inclined slide corresponding to the right end of the first slide 11; The base plate 10 is fixedly connected to the baffle 13 on the side away from the second slide 12; Through the suction pipe 25, extraction pipe 21 and extraction pump 20 set on the cutting device, the medicine glass tube can be cut open while the fine glass fragments are extracted into the extraction pipe 21, which improves the cutting efficiency and prevents the presence of fine glass fragments in the medicine glass tube from affecting the subsequent medicine filling.

[0019] Please see Figure 2-3 The cutting device includes at least an L-shaped support plate 18; the L-shaped support plate 18 is threadedly connected to a lead screw 17; the L-shaped support plate 18 is rotatably connected to a blade 22 and a retaining ring 26; the blade 22 and the retaining ring 26 are concentrically arranged; six gear shafts 23 are embedded between the blade 22 and the retaining ring 26; bearings 24 are sleeved on the rear side of the five lower gear shafts 23; each bearing 24 abuts against the L-shaped support plate 18; the L-shaped support plate 18 is fixedly connected to a motor 19; the motor... The output end of the 29 is fixedly connected to the uppermost gear shaft 23; each gear shaft 23 is fixedly connected to an internal gear 27 on the side away from the L-shaped support plate 18; the blade 22 is fixedly connected to an external gear ring 28 at the position corresponding to the internal gear 27; the external gear ring 28 meshes with the six internal gears 27; the inner side of the internal gear 27 abuts against the retaining ring 26; the end of the retaining ring 26 near the internal gear 27 is fixedly connected to the suction pipe 25; each gear shaft 23 is rotatably connected to the L-shaped support plate 18.

[0020] Please see Figure 1 A pair of sliding rods 16 are fixedly connected between the two brackets 14; the L-shaped support plate 18 is slidably connected to the pair of sliding rods 16.

[0021] Please see Figure 1 The blade 22 is made of stainless steel.

[0022] Please see Figure 1There is a gap between the slide rail 12 and the baffle 13; by setting the L-shaped support plate 18, gear shaft 23, internal gear 27 and external gear ring 28, the external gear ring 28 can be stabilized and rotated at the same time, thereby improving the precision cutting efficiency.

[0023] During operation, the raw material is placed on slide rail 11 and then slides down from slide rail 11. After the raw material partially extends into slide rail 12, motor 15 is started, which drives the lead screw 17 to rotate. The rotation of the lead screw 17 moves the L-shaped support plate 18. At this time, motor 29 is started. The output end of motor 29 drives the uppermost internal gear 27. After the uppermost internal gear 27 rotates, it drives the external gear ring 28 to rotate. During the rotation of the external gear ring 28, the other internal gears 27 rotate, stabilizing the external gear ring 28 while allowing it to rotate. Since the external gear ring 28 is fixedly connected to the blade 22, the blade 22 can rotate to cut the raw material.

[0024] When the blade 22 cuts the raw material, the suction pump 20 is started. The suction pump 20 generates suction, which causes the suction pipe 21 to pass through the suction pipe 25 and suck the small glass fragments into the suction pipe 21. The glass fragments that are not sucked into the suction pipe 21 by the suction pipe 25 fall from the gap between the slide 11 and the slide 22. Some small glass fragments can also fall from the gap between the slide 22 and the baffle 13.

[0025] Take the raw material from the gap between slide 12 and baffle 13, then remove the cut medicine glass tube, activate bracket 14 to reset L-shaped support plate 18, and proceed with the next cut;

[0026] Repeating the above steps can quickly cut the medicine glass tube, and at the same time, it can draw the fine glass shards into the slide 11, or let them fall off naturally, improving the safety of the medicine glass tube.
