Description

Technical Field

[0001] The present invention relates to the technical field of glass tube production, and in particular to an automatic cutting device for glass tube production. Background Art

[0002] In social production and life, glass tubes are widely used. They can be used in various fields such as electric light sources, semiconductors, optical communications, military industry, metallurgy, building materials, chemistry, machinery, electricity, environmental protection, etc. In the existing technology, glass tubes can generally be divided into four types: 1. Ordinary glass tubes, such as those used in laboratories; 2. Chemical glass tubes, which are usually made of boron glass with good thermal stability and corrosion resistance, are transparent, easy to clean, have low flow resistance, and are inexpensive; 3. Neutral glass tubes; 4. High borosilicate glass tubes.

[0003] During the processing of glass tubes, the formed glass tubes are usually transported horizontally by a conveying device, and its moving direction is parallel to the length direction of the glass tubes. During this process, the cutting device needs to cut the glass tubes into multiple standard small sections according to the specified length, and at the same time cut the shorter glass tubes into waste. However, the cutting device in the prior art has the following problems:

[0004] Existing cutting devices usually adopt a single cutting arm design, which is difficult to adapt to the cutting needs of glass tubes of different specifications (such as different diameters, lengths and materials). For example, when cutting high borosilicate glass tubes, due to their high hardness, greater cutting force is required; while when cutting ordinary glass tubes, more precise cutting control is required to avoid breakage. The design of a single cutting arm cannot flexibly adjust cutting parameters (such as cutting pressure, cutting position, cutting speed, etc.), resulting in unstable cutting quality and even glass tube breakage.

[0005] Existing cutting devices usually use a single cutting arm structure, and the motor can only complete one cutting operation per rotation, which cannot meet the needs of high-efficiency production. Although the cutting frequency can be increased by increasing the motor speed, this can easily cause the cutting arm to derail or vibrate too much, which in turn causes problems such as cutting position deviation and uneven glass tube cuts, which seriously affects product quality. In addition, the degree of automation is low, and manual intervention is usually required to adjust cutting parameters or replace cutting tools, which can easily lead to material waste and low production efficiency.

[0006] Therefore, there is a contradiction between cutting efficiency and cutting quality in the existing technology, and it is difficult to meet the needs of high-speed production and high-quality cutting at the same time. It is urgent to develop a glass tube cutting device that can adapt to various glass tube cutting needs, improve cutting efficiency and achieve high automation to meet the needs of modern industrial production.

DETAILED DESCRIPTION

[0020] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with examples. The examples are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0021] The glass tube cutting machine of the present invention can significantly improve the cutting efficiency while maintaining the cut glass tube length unchanged by adjusting the cutting arm length through a sliding frame, coordinated operation of multiple cutting arms, and precise control of a telescopic cutter head, thereby solving the problems of low cutting efficiency, complex adjustment, and insufficient precision in the prior art.

[0022] according to Figure 1-Figure 5 As shown, an automatic cutting device for glass tube production includes a main frame 1 and a plurality of feeding components arranged on one side of the main frame 1, wherein the feeding components include a support rod 11 and a feeding roller 12, wherein the support rod 11 is arranged on the top of one side of the main frame 1, and a feeding roller 12 is arranged on one side of the top of the support rod 11, wherein the feeding component is used to transmit a glass tube 121 to realize automatic feeding, wherein a support column 13 is arranged in the middle of the main frame 1, and a rotating cutting component for cutting the glass tube 121 is arranged above the support column 13, wherein continuous transportation of the glass tube 121 is realized by the feeding component, and the cutting action is completed by the rotating cutting component;

[0023] The rotary cutting component includes a rotating mechanism, a telescopic mechanism 15 and a steering mechanism. The rotating mechanism includes a first motor 141 arranged at the top of the main frame 1, and the output end of the first motor 141 is fixedly connected to a first threaded sleeve 142; the telescopic mechanism 15 includes a first threaded rod 151 spirally connected to the inner side of the first threaded sleeve 142, and a sliding frame 152 is fixedly arranged at the bottom of the first threaded rod 151, and a first sliding groove is opened on the sliding frame 152, and a first sliding rod 153 is slidably arranged in the first sliding groove. A sliding cylinder 154 is sleeved on the outer side of the first threaded sleeve 142, and the upper and lower ends of the outer side of the sliding cylinder 154 are respectively rotatably connected to one end of a connecting rod 155, and the other end of the connecting rod 155 is divided into The telescopic mechanism 15 is rotatably connected to the upper and lower ends of the first sliding rod 153. A telescopic motor 156 is provided at the top of the support column 13. The output end of the telescopic motor 156 is rotatably connected to the bottom of the sliding frame 152. A cutting arm 16 is provided on the outside of the telescopic mechanism 15. A cutting mechanism 17 is provided at one end of the cutting arm 16. The bottom end of the telescopic mechanism 15 is connected to a steering mechanism; the rotating mechanism is used to drive the rotating cutting component to rotate and adjust the cutting efficiency; the telescopic mechanism 15 is used to achieve telescopic movement through threaded connection and adjust the radius of the cutting arm 16; the steering mechanism is used to adjust the rotation direction of the rotating disk 163 through mechanical linkage, and then adjust the cutting position accordingly to achieve multi-angle cutting, and finally the cutting of the glass tube 121 is completed by the cutting mechanism 17.

[0024] The first sliding grooves and the first sliding rods 153 are each provided with a plurality of corresponding groups. Through the cooperation of the plurality of first sliding grooves and the first sliding rods 153, the stability of the cutting arm 16 is enhanced, and at the same time, the number of cutting arms 16 is allowed to be increased or decreased, so as to flexibly match the cutting requirements of glass tubes 121 of different lengths.

[0025] One end of a cutting arm 16 is rotatably provided on one side of the first sliding rod 153, and a cutting mechanism 17 is provided on the other end of the cutting arm 16. A second sliding groove is opened on one side of the cutting arm 16, and a sliding block 161 is slidably provided in the second sliding groove. A positioning roller 162 is rotatably provided on one end of the sliding block 161. A rotating disk 163 is rotatably provided above the support column 13, and a rolling groove corresponding to the positioning roller 162 is provided on the rotating disk 163. The cutting arm 16 moves along the rolling groove of the rotating disk 163 through the sliding block 161 and the positioning roller 162 to achieve cutting. The design of the second sliding groove and the sliding block 161 enables the cutting arm 16 to remain stable during the movement.

[0026] The steering mechanism includes a rotating gear 166 and a rack 167. The rotating gear 166 is provided at the center of the top of the rotating disk 163. The bottom end of any of the first sliding rods 153 passes through the first sliding groove and is connected to the rack 167. The extension direction of the rack 167 is consistent with the axial direction of the first sliding groove, and the rack 167 is meshed with the rotating gear 166. When the first sliding rod 153 moves with the telescopic mechanism 15, the rack 167 is meshed with the rotating gear 166 to drive the rotating disk 163 to rotate, thereby realizing dynamic adjustment of the cutting position.

[0027] The rotating disk 163 has a slope, and there is a height difference between the head and tail ends of the rolling groove, which is used to guide the cutting arm 16 to move along the path of the rolling groove to the drop of the rolling groove, that is, the position where the height of the rolling groove suddenly decreases. The cutting arm 16 and the glass cutter head 181 installed thereon will fall under the action of gravity, thereby contacting the glass tube 121 placed on the feeding component and achieving cutting.

[0028] A fixing block 164 is provided on the outer side of the bottom of the sliding frame 152, and one end of a spring 165 is provided above the fixing block 164. The other end of the spring 165 is connected to the top of the end of the cutting arm 16 close to the sliding frame 152. The design of the fixing block 164 and the spring 165 is to provide a reset force for the cutting arm 16 after it falls at the drop, ensuring that the cutting arm 16 can quickly and stably return to its initial position; and secondly, to provide a buffering effect when the cutting arm 16 falls, reducing the vibration and impact caused by cutting.

[0029] In this embodiment, the position with a height difference between the head and tail ends of the rolling groove is located near the end of the feeding component. When the cutting arm 16 rotates to the drop position, the positioning roller 162 falls from the position where the height of the rolling groove suddenly decreases, driving the cutting arm 16 and the glass cutter head 181 installed thereon to fall under the action of gravity and quickly cut the glass tube 121. Under the action of the spring 165, the cutting arm 16 is provided with an upward restoring force and a buffering force to reduce the cutting arm 16 when it falls, so that the cutting arm 16 continues to move along the rolling groove in the rotating disk 163, and the cutting work is continuously and evenly maintained.

[0030] The first motor 141 in the rotating mechanism drives the first threaded sleeve 142 to rotate, thereby driving the first threaded rod 151 and the telescopic mechanism 15 to rotate, and the movement of the telescopic motor 156 drives the sliding frame 152 and the first threaded rod 151 thereon to move;

[0031] When the telescopic motor 156 moves the sliding frame 152 and the first threaded rod 151 thereon downward, it drives the sliding cylinder 154 to move downward, and is driven by the connecting rod 155 between the sliding cylinder 154 and the first sliding rod 153, thereby driving the first sliding rod 153 to slide into the first sliding groove away from the center of the sliding frame 152. At the same time, the sliding block 161 on the cutting arm 16 moves in the second sliding groove toward the center of the rotating disk 163, so that the positioning roller 162 continues to remain in the moving trajectory of the rolling groove, thereby adjusting the length of the cutting arm 16, allowing the cutting arm 16 to rotate through the rotating mechanism, and then swinging and cutting within a certain range. The telescopic mechanism 15 synchronously links the steering mechanism to move, and the first sliding rod 153 slides in the first sliding groove, driving the rack 167 to move, thereby driving the rotating gear 166 meshing therewith to move, driving the rotating disk 163 to rotate, thereby affecting the position of the drop of the slope of the rotating disk 163, and thereby changing the cutting position of the cutting arm 16.

[0032] In the present embodiment, the cutting mechanism 17 further comprises a fixed shell 171 connected to the side of the cutting arm 16, one end of the fixed shell 171 is provided with a first bracket 172, a placement slot is provided in the fixed shell 171, a second motor is provided in the placement slot, an output shaft of the second motor passes through one end of the first bracket 172 and is connected to one end of a second threaded rod 174, the other end of the second threaded rod 174 is rotatably connected to the middle of the first bracket 172, a second bracket 175 is provided below the first bracket 172, two groups of second sliding rods 176 are symmetrically provided on the first bracket 172 and the second bracket 175, two ends of a second threaded sleeve 177 are slidably provided on the outer sides of the two groups of second sliding rods 176 on the first bracket 172, and the two groups of second threaded sleeves 177 on the second bracket 175 are slidably provided. The outer sides of the two sliding rods 176 are respectively slidably provided with two ends of a third threaded sleeve 178, and the two ends of the second threaded sleeve 177 are respectively rotatably connected to one end of a first connecting rod 179, and the other end of the first connecting rod 179 is respectively rotatably connected to one end of the second bracket 175, and the two ends of the third threaded sleeve 178 are respectively rotatably connected to one end of a second connecting rod 180, and the other end of the second connecting rod 180 is respectively rotatably connected to one end of the first bracket 172, and the middle parts of the first connecting rod 179 and the second connecting rod 180 are cross-rotatably connected, and the second threaded rod 174 passes through and is threadedly connected to the middle part of the second threaded sleeve 177, and a glass cutter head 181 is provided at the bottom of the second bracket 175, and the second motor drives the second threaded rod 174 to adjust the height of the glass cutter head 181 to achieve precise cutting operation.

[0033] The second motor drives the second threaded rod 174 to rotate, thereby driving the second threaded sleeve 177 to move on the second sliding rod 176 on the first bracket 172, and through the linkage action of the first connecting rod 179 and the second connecting rod 180, the third threaded sleeve 178 is synchronously driven to move on the second sliding rod 176 on the second bracket 175, thereby driving the distance between the second bracket 175 and the first bracket 172 to move, and driving the height adjustment of the glass cutter head 181.

[0034] Embodiment 1: Cutting length remains unchanged and cutting efficiency is improved. When the conveying speed of the glass tube remains unchanged, it is necessary to keep the cutting length unchanged but improve the efficiency, which can be achieved by adjusting the rotation radius and number of the cutting arms 16 and the rotation speed of the first motor 141 .

[0035] In this embodiment, preferably, by increasing the rotation radius and the number of cutting arms 16, when the glass tube conveying speed V remains unchanged, the number of cutting arms 16 can be increased from 1 to 2, and the two groups of cutting arms 16 are symmetrically installed with a phase difference of 180°, and the motor speed ω of the first motor 141 is reduced from the original speed ω to 50% ( = 0.5ω), so that the rotation period from Increase to adjusted rotation period = , cutting interval time Δ = , that is, the cutting interval remains unchanged; the cutting length L remains unchanged: L=V×Δ =V× =L.

[0036] Through this solution, under the premise of ensuring that the cutting length and feeding speed remain unchanged, only by increasing the number of cutting arms 16 and synchronously reducing the speed of the first motor 141, there is no need to modify the core mechanical structure. Through the precise matching of the speed and the feeding speed, the cutting length is ensured to remain unchanged, and the efficiency is improved only by adjusting the parameters, which is easy to operate; by reducing the speed of the first motor 141, it can avoid vibration or derailment caused by high-speed rotation, while maintaining cutting efficiency. Multiple cutting arms 16 work together to share the cutting pressure, reduce the load of a single cutting arm 16, and further improve the stability and accuracy of cutting.

[0037] Embodiment 2: Cutting glass tubes of different lengths needs to meet the cutting requirements of glass tubes of different specifications. Flexible production can be achieved by adjusting the length and number of the cutting arms 16 and the configuration of the glass cutter heads 181.

[0038] Cutting length L = V × Δt, where V is the conveying speed and Δt is the cutting interval time.

[0039] Adjustment of the length of the cutting arm 16: By changing the rotation radius R, the cutting interval time Δt is indirectly affected.

[0040] Long cutting arm mode (suitable for large diameter glass tubes): the cutting arm 16 is extended, the speed of the first motor 141 is reduced, and the cutting arm 16 rotates slowly to ensure that each cutting length is longer;

[0041] Short cutting arm mode (suitable for small diameter glass tubes): shorten the cutting arm 16, increase the speed of the first motor 141, and the cutting arm 16 rotates quickly to complete multiple cuts in a short time (suitable for thin-walled tubes used in laboratories);

[0042] Multiple cutting arms work together to cut short tubes in batches and process long tubes efficiently.

[0043] In this embodiment, the cutting mechanism 17 preferably drives the second threaded rod 174 through the second motor, links the first connecting rod 179 and the second connecting rod 180, controls the lifting and lowering of the second bracket 175, and realizes the precise adjustment of the height of the glass cutter head 181. The height of the glass cutter head 181 is adjustable to ensure uniform cutting pressure and avoid cutting and breaking due to changes in the diameter of the glass tube. The cutting length and the height of the glass cutter head 181 can be quickly adjusted to quickly adapt to glass tubes of different specifications (length, diameter). One set of equipment can adapt to multiple specifications, and can quickly switch from small laboratory tubes to large industrial tubes.

[0044] Adjusting the length of the cutting arm 16 is not only a means of controlling the cutting position, but also ensures cutting accuracy while improving efficiency through matching the length and rotation speed, thus achieving efficient and low-consumption production. By adjusting the length, rotation speed and number of the cutting arms 16, the diversified needs from short pipes to long pipes can be covered; the detachable cutter head design supports rapid adaptation to different pipe diameters, improving the versatility of the equipment; multiple cutting arms 16 work together to achieve efficient completion of complex cutting tasks and complete multiple cutting operations at the same time, solving the problem of low efficiency of a single cutting arm 16, and ensuring the consistency and stability of cutting through precise synchronous control; multiple cutting arms 16 can perform cutting operations at the same time, sharing the cutting pressure, reducing the load of a single cutting arm 16, and further improving the stability and accuracy of cutting.
