Description

Technical Field

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

[0002] In social production and life, glass tubes are widely used and can be applied to various fields such as electric light sources, semiconductors, optical communications, military industry, metallurgy, building materials, chemistry, machinery, electric power, and environmental protection. In the prior art, glass tubes can generally be divided into four types: 1. Ordinary glass tubes, such as those used in laboratories, etc.; 2. Chemical glass tubes, usually made of borosilicate glass with good thermal stability and corrosion resistance, transparent, easy to clean, with small flow resistance, and low price; 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 tube. During this process, the cutting device needs to cut the glass tube into multiple standard small segments according to the specified length, and at the same time perform waste cutting on shorter glass tubes. However, the cutting devices in the prior art have the following problems:

[0004] Existing cutting devices usually adopt a single cutting arm design, which is difficult to meet the cutting requirements 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 needed 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 breakage of glass tubes.

[0005] Existing cutting devices usually adopt a single cutting arm structure. Each time the motor rotates one circle, only one cutting operation can be completed, which cannot meet the requirements of high-efficiency production. Although the cutting frequency can be increased by increasing the motor speed, this is likely to cause the cutting arm to derail or vibrate too much, resulting in problems such as deviation of the cutting position and uneven cut of the glass tube, seriously affecting the product quality, and the degree of automation is low. Usually, manual intervention is required to adjust cutting parameters or replace cutting tools, which is likely to cause material waste and low production efficiency.

[0006] Therefore, there is a contradiction between cutting efficiency and cutting quality in the prior art, and it is difficult to meet the requirements of high-speed production and high-quality cutting at the same time. There is an urgent need to develop a glass tube cutting device that can adapt to the cutting requirements of various glass tubes, improve cutting efficiency, and achieve high automation to meet the needs of modern industrial production. Summary of the Invention

[0007] To achieve the above object of the present invention, the present invention is implemented through the following technical solutions: An automatic cutting device for glass tube production, comprising a main body frame and a plurality of groups of feeding components arranged on one side of the main body frame. The feeding components include support rods and feeding rollers. The support rods are arranged at the top of one side of the main body frame, and feeding rollers are provided on one side of the top of the support rods. The feeding components are used to transport glass tubes to achieve automatic feeding. A support column is provided in the middle of the main body frame, and a rotary cutting component for cutting glass tubes is provided above the support column. The continuous transportation of glass tubes is realized through the feeding components, and the cutting action is completed through the rotary cutting component;

[0008] The rotary cutting component includes a rotating mechanism, a telescopic mechanism and a steering mechanism. The rotating mechanism includes a first motor arranged at the top of the main body frame, and the output end of the first motor is fixedly connected with a first threaded sleeve; the telescopic mechanism includes a first threaded rod screwed inside the first threaded sleeve.

The upper and lower ends of the outside of the sliding cylinder are respectively rotatably connected with one end of a connecting rod, and the other end of the connecting rod is respectively rotatably connected with the upper and lower ends of the first sliding rod. An expansion motor is provided at the top of the support column, and the output end of the expansion motor is rotatably connected to the bottom of the sliding frame. A cutting arm is provided outside the telescopic mechanism, and a cutting mechanism is provided at one end of the cutting arm. The bottom end of the telescopic mechanism is connected to the steering mechanism; the rotating mechanism is used to drive the rotary cutting component to rotate and adjust the cutting efficiency; the telescopic mechanism is used to achieve telescopic movement through threaded connection and adjust the radius of the cutting arm; the steering mechanism is used to adjust the rotation direction of the cutting arm through mechanical linkage, and then correspondingly adjust the cutting position to achieve multi-angle cutting. Finally, the glass tube cutting is completed by the cutting mechanism.

[0009] A further improvement lies in that: A plurality of groups of the first sliding grooves and the first sliding rods are respectively provided. Through the cooperation of multiple groups of sliding grooves and sliding rods, the stability of the cutting arm is enhanced, and at the same time, the number of cutting arms can be increased or decreased to flexibly match the cutting requirements of glass tubes of different lengths.

[0010] A further improvement lies in that: One end of the cutting arm is rotatably provided on one side of the first sliding rod, and a cutting mechanism is provided at the other end of the cutting arm. A second sliding groove is opened on one side of the cutting arm, and a sliding block is slidably arranged in the second sliding groove. A positioning roller is rotatably provided at one end of the sliding block. A rotating disk is rotatably provided above the support column, and a rolling groove corresponding to the positioning roller is provided on the rotating disk. The cutting arm moves along the rolling groove of the rotating disk through the sliding block and the positioning roller to achieve cutting; the design of the second sliding groove and the sliding block enables the cutting arm to maintain stability during the movement process.

[0011] A further improvement lies in that: the steering mechanism includes a rotating gear and a rack. A rotating gear is provided at the center of the top end of the rotating disk. The bottom end of any one of the first sliding rods penetrates through the first sliding groove and is connected with a rack. The extending direction of the rack is consistent with the axial direction of the first sliding groove, and the rack meshes with the rotating gear. When the first sliding rod moves along with the telescopic mechanism, the rack and the rotating gear are engaged and driven to drive the rotating disk to rotate, realizing the dynamic adjustment of the cutting position.

[0012] A further improvement lies in that: the cutting mechanism includes a fixed shell connected to the side of the cutting arm. A first bracket is provided at one end of the fixed shell. A placement groove is opened in the fixed shell. A second motor is provided in the placement groove. The output shaft of the second motor penetrates through one end of the first bracket and is connected with one end of a second threaded rod. The other end of the second threaded rod is rotatably connected to the middle of the first bracket. A second bracket is provided below the first bracket. Two groups of second sliding rods are symmetrically provided on both the first bracket and the second bracket respectively. The two ends of a second threaded sleeve are respectively slidably provided on the outer sides of the two groups of second sliding rods on the first bracket, and the two ends of a third threaded sleeve are respectively slidably provided on the outer sides of the two groups of second sliding rods on the second bracket. The two ends of the second threaded sleeve are respectively rotatably connected to one end of a first connecting rod. The other ends of the first connecting rods are respectively rotatably connected to one end of the second bracket.

The second threaded rod penetrates through and is threadedly connected to the middle of the second threaded sleeve. A glass cutter head is provided at the bottom of the second bracket, which is used to drive the threaded rod through the second motor, thereby adjusting the height of the glass cutter head and realizing precise cutting operation.

[0013] A further improvement lies in that: the rotating disk has a slope, and there is a height difference between the head and the tail ends of the rolling groove. When guiding the cutting arm to move along the path of this rolling groove to the position where the height of the rolling groove suddenly decreases, that is, the position where the height of the rolling groove drops suddenly, the cutting arm and the glass cutter head installed thereon will fall under the action of gravity, so as to contact the glass tube placed on the feeding component and realize cutting.

[0014] A further improvement lies in that: a fixed block is provided on the outer side of the bottom of the sliding frame. One end of a spring is provided above the fixed block. The other end of the spring is connected to the top of one end of the cutting arm close to the sliding frame. The design of the fixed block and the spring is, firstly, to provide a restoring force for the cutting arm after it falls at the drop position to ensure that the cutting arm can quickly and stably return to the initial position; secondly, to provide a buffering effect when the cutting arm falls to reduce the vibration and impact generated by cutting.

[0015] 1. Through the adjusted number of cutting arms and the design of telescopic cutting arms, the present invention can adapt to the cutting requirements of glass tubes of different specifications. By increasing or decreasing the number of the first sliding grooves and the first sliding rods, the number of cutting arms can be adjusted to adapt to the cutting requirements of glass tubes with different lengths and diameters; the telescopic mechanism realizes the telescoping of the cutting arms through threaded connection, can adjust the rotation radius of the cutting arms and is synchronously linked through the steering mechanism to adjust the cutting position to adapt to the cutting of glass tubes of different specifications; the cutting mechanism drives the threaded rod through the second motor to adjust the height of the glass cutter head to ensure that glass tubes of different diameters can be accurately cut. Through the adjustment of the length and number of the cutting arms and the matching with the rotation speed, while improving the efficiency, the cutting accuracy is guaranteed, realizing high-efficiency and low-consumption production.

[0023] To deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments. These embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0024] The glass tube cutting machine of the present invention can significantly improve the cutting efficiency while keeping the cutting length of the glass tube unchanged by adjusting the length of the cutting arm through the sliding frame, the coordinated work of multiple cutting arms, and the precise control of the telescopic cutter head, solving the problems of low cutting efficiency, complex adjustment, and insufficient precision in the prior art.

[0025] According to Figures 1 - 5 As shown in the figure, an automatic cutting device for glass tube production includes a main body frame 1 and a plurality of sets of feeding components arranged on one side of the main body frame 1. The feeding components include a support rod 11 and a feeding roller 12. The support rod 11 is arranged at the top on one side of the main body frame 1, and a feeding roller 12 is provided on one side of the top of the support rod 11. The feeding components are used to transport the glass tube 121 to achieve automatic feeding. A support column 13 is arranged in the middle of the main body frame 1, and a rotary cutting component for cutting the glass tube 121 is provided above the support column 13. The continuous transportation of the glass tube 121 is realized through the feeding components, and the cutting action is completed through the rotary cutting component;

[0026] The rotary cutting component includes a rotary mechanism, a telescopic mechanism 15 and a steering mechanism. The rotary mechanism includes a first motor 141 disposed at the top of the main body frame 1, and the output end of the first motor 141 is fixedly connected with a first threaded sleeve 142. The telescopic mechanism 15 includes a first threaded rod 151 screwed inside the first threaded sleeve 142. The bottom of the first threaded rod 151 is fixedly provided with a sliding frame 152. A first sliding groove is formed in the sliding frame 152, and a first sliding rod 153 is slidably disposed in the first sliding groove. A sliding cylinder 154 is sleeved outside the first threaded sleeve 142. The upper and lower ends of the outside of the sliding cylinder 154 are respectively rotatably connected with one end of a connecting rod 155, and the other ends of the connecting rod 155 are respectively rotatably connected with the upper and lower ends of the first sliding rod 153. The top of the support column 13 is provided with a telescopic motor 156, and the output end of the telescopic motor 156 is rotatably connected to the bottom of the sliding frame 152. A cutting arm 16 is disposed outside the telescopic mechanism 15. A cutting mechanism 17 is disposed at one end of the cutting arm 16. The bottom end of the telescopic mechanism 15 is connected to the steering mechanism. The rotary mechanism is used to drive the rotary 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 rotary disk 163 through mechanical linkage, and then correspondingly adjust the cutting position to achieve multi-angle cutting. Finally, the glass tube 121 is cut by the cutting mechanism 17.

[0027] A plurality of groups of the first sliding grooves and the first sliding rods 153 are correspondingly provided. Through the cooperation of the plurality of groups of the 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 the cutting arms 16 can be increased or decreased to flexibly match the cutting requirements of glass tubes 121 with different lengths.

[0028] One end of the cutting arm 16 is rotatably provided on one side of the first sliding rod 153. A cutting mechanism 17 is disposed at the other end of the cutting arm 16. A second sliding groove is formed in one side of the cutting arm 16, and a sliding block 161 is slidably disposed in the second sliding groove. A positioning roller 162 is rotatably provided at one end of the sliding block 161. A rotary disk 163 is rotatably provided above the support column 13. A rolling groove corresponding to the positioning roller 162 is provided on the rotary disk 163. The cutting arm 16 moves along the rolling groove of the rotary 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.

[0029] The steering mechanism includes a rotating gear 166 and a rack 167. A rotating gear 166 is provided at the center of the top end of the rotating disk 163. The bottom end of any one of the first sliding rods 153 penetrates through the first sliding groove and is connected to a rack 167. The extending direction of the rack 167 is consistent with the axial direction of the first sliding groove, and the rack 167 meshes with the rotating gear 166. When the first sliding rod 153 moves with the telescopic mechanism 15, the rack 167 and the rotating gear 166 are in meshing transmission to drive the rotating disk 163 to rotate, realizing the dynamic adjustment of the cutting position;

[0030] The rotating disk 163 has a slope, and there is a height difference between the head and the tail of the rolling groove. When the cutting arm 16 is guided to move along the path of this rolling groove to the drop position 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 mounted thereon will fall under the action of gravity, so as to contact the glass tube 121 placed on the feeding component and realize cutting.

[0031] A fixing block 164 is provided on the outer side of the bottom of the sliding frame 152. One end of a spring 165 is provided above the fixing block 164, and the other end of the spring 165 is connected to the top of one end of the cutting arm 16 close to the sliding frame 152. The design of the fixing block 164 and the spring 165 is, firstly, to provide a restoring force for the cutting arm 16 after it falls at the drop position to ensure that the cutting arm 16 can quickly and stably return to the initial position; secondly, to provide a buffering effect when the cutting arm 16 falls to reduce the vibration and impact generated by cutting.

[0032] In this embodiment, the position with a height difference between the head and the tail of the rolling groove is located at the end close to 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 mounted thereon to fall under the action of gravity and quickly cut the glass tube 121. Under the action of the spring 165, an upward restoring force is provided for the cutting arm 16 and the buffering force when the cutting arm 16 falls is reduced, so that the cutting arm 16 continues to move along the rolling groove in the rotating disk 163 and continuously and evenly maintains the cutting work.

[0033] By the rotation of the first motor 141 in the rotating mechanism driving the rotation of the first threaded sleeve 142, and then driving the rotation of the first threaded rod 151 and the telescopic mechanism 15, and through the movement of the telescopic motor 156, the movement of the sliding frame 152 and the first threaded rod 151 thereon is driven;

[0034] 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. Driven by the connecting rod 155 between the sliding cylinder 154 and the first sliding rod 153, the first sliding rod 153 is further driven to slide away from the center of the sliding frame 152 in the first sliding groove. At the same time, the sliding block 161 on the cutting arm 16 moves closer to the center of the rotating disk 163 in the second sliding groove, so that the positioning roller 162 continues to stay within the moving track of the rolling groove, realizing the length adjustment of the cutting arm 16. The cutting arm 16 is allowed to rotate driven by the rotating mechanism, swing within a certain range and cut subsequently. The telescopic mechanism 15 synchronously drives the steering mechanism to move. The first sliding rod 153 slides in the first sliding groove, driving the rack 167 to move, and then driving the rotating gear 166 engaged therewith to move, driving the rotating disk 163 to rotate, thereby affecting the position of the slope drop of the rotating disk 163, and then changing the cutting position of the cutting arm 16.

[0035] In this embodiment, further, the cutting mechanism 17 includes 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 groove is opened in the fixed shell 171. A second motor is arranged in the placement groove. The output shaft of the second motor penetrates 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 arranged below the first bracket 172. Two groups of second sliding rods 176 are symmetrically arranged on both the first bracket 172 and the second bracket 175 respectively. The two ends of a second threaded sleeve 177 are respectively slidably arranged on the outer sides of the two groups of second sliding rods 176 on the first bracket 172, and the two ends of a third threaded sleeve 178 are respectively slidably arranged on the outer sides of the two groups of second sliding rods 176 on the second bracket 175. One end of a first connecting rod 179 is respectively rotatably connected to the two ends of the second threaded sleeve 177. The other end of the first connecting rod 179 is respectively rotatably connected to one end of the second bracket 175. One end of a second connecting rod 180 is respectively rotatably connected to the two ends of the third threaded sleeve 178. The other end of the second connecting rod 180 is respectively rotatably connected to one end of the first bracket 172. The middle parts of the first connecting rod 179 and the second connecting rod 180 are cross-rotatably connected. The second threaded rod 174 penetrates through and is threadedly connected to the middle of the second threaded sleeve 177. A glass cutter head 181 is arranged at the bottom of the second bracket 175. The second motor drives the second threaded rod 174, thereby adjusting the height of the glass cutter head 181 to realize precise cutting operation.

[0036] By driving the rotation of the second threaded rod 174 with the second motor, the movement of the second threaded sleeve 177 on the second sliding rod 176 of the first bracket 172 is driven, and through the linkage of the first connecting rod 179 and the second connecting rod 180, the movement of the third threaded sleeve 178 on the second sliding rod 176 of the second bracket 175 is synchronously driven, thereby driving the movement of the distance between the second bracket 175 and the first bracket 172, and driving the height adjustment of the glass cutter head 181.

[0037] Embodiment 1: Keep the cutting length unchanged and improve the cutting efficiency. When the conveying speed of the glass tube remains unchanged, to keep the cutting length unchanged but improve the efficiency, it can be achieved by adjusting the rotation radius, quantity of the cutting arm 16 and the rotation speed of the first motor 141.

[0038] Preferably in this embodiment, by increasing the rotation radius and the quantity of the cutting arm 16, when the conveying speed V of the glass tube remains unchanged, it can also be achieved by increasing the cutting arm 16 from 1 to 2, the two groups of cutting arms 16 are symmetrically installed with a phase difference of 180°, and reducing the rotation speed ω of the first motor 141 from the original speed ω to 50% ( =0.5ω), so that the rotation period changes from to the adjusted rotation period = , and the cutting interval time Δ = , that is, the cutting interval time remains unchanged; the cutting length L remains unchanged: L = V×Δ = V× = L.

[0039] Through this solution, on the premise of ensuring that the cutting length and the feeding speed remain unchanged, only by increasing the quantity of the cutting arm 16 and synchronously reducing the rotation speed of the first motor 141, there is no need to transform the core mechanical structure. Through the precise matching of the rotation speed and the feeding speed, it is ensured that the cutting length remains unchanged, and the efficiency is improved only through parameter adjustment, which is easy to operate; by reducing the rotation speed of the first motor 141, it is possible to avoid vibration or derailment caused by high-speed rotation, while maintaining the cutting efficiency. Multiple cutting arms 16 work together, sharing the cutting pressure and reducing the load of a single cutting arm 16, further improving the cutting stability and accuracy.

[0040] Embodiment 2: Cut glass tubes of different lengths. To meet the cutting requirements of different specifications of glass tubes, flexible production can be achieved by adjusting the length, quantity of the cutting arm 16 and the configuration of the glass cutter head 181.

[0041] The cutting length L = V×Δt, where V is the conveying speed and Δt is the cutting interval time.

[0042] Cutting arm 16 length adjustment: By changing the rotation radius R, the cutting interval time Δt is indirectly affected.

[0043] Long cutting arm mode (applicable to large-diameter glass tubes): Extend the cutting arm 16, reduce the rotation speed of the first motor 141, and slowly rotate the cutting arm 16 to ensure that each cutting length is longer;

[0044] Short cutting arm mode (applicable to small-diameter glass tubes): Shorten the cutting arm 16, increase the rotation speed of the first motor 141, and quickly rotate the cutting arm 16 to complete multiple cuts in a short time (suitable for thin-walled tubes in laboratories);

[0045] Multiple cutting arms cooperate with each other, enabling batch cutting of short tubes and efficient processing of long tubes.

[0046] Preferably in this embodiment, the cutting mechanism 17 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 of the second bracket 175, and realizes 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 breakage caused by changes in the diameter of the glass tube. By quickly adjusting the cutting length and the height of the glass cutter head 181, different specifications (length, diameter) of glass tubes can be quickly adapted. One set of equipment can adapt to multiple specifications and can be quickly switched from small laboratory tubes to large industrial tubes.

[0047] The adjustment of the length of the cutting arm 16 is not only a means of controlling the cutting position. By matching the length and rotation speed, while improving efficiency, it ensures cutting accuracy and realizes high-efficiency and low-consumption production. By adjusting the length, rotation speed, and number of the cutting arms 16, diverse requirements from short tubes to long tubes are covered; the detachable cutter head design supports quick adaptation to different pipe diameters and improves the versatility of the equipment; multiple cutting arms 16 work together to efficiently complete complex cutting tasks and perform multiple cutting operations simultaneously, solving the problem of low efficiency of a single cutting arm 16. At the same time, through precise synchronous control, the consistency and stability of cutting are ensured; multiple cutting arms 16 can perform cutting operations simultaneously, sharing the cutting pressure and reducing the load on a single cutting arm 16, further improving the stability and accuracy of cutting.

[0048] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
