Description

Technical Field

[0001] This invention relates to the field of glass tube processing equipment technology, and in particular to a glass tube cutting machine. Background Technology

[0002] Glass tubes are widely used in medical, chemical, lighting, and laboratory instrument fields. In actual production, long glass mother tubes need to be cut into several short tubes according to specifications, and the cut edges need to be smoothed to meet subsequent assembly or usage requirements. Traditional glass tube cutting processes mostly use manual feeding, manual alignment, and flame heating before cutting, which has the following problems: 1. Low efficiency of manual operation: a single skilled worker can only complete the cutting of 8-12 glass tubes per minute, which is difficult to meet the needs of mass production; 2. Poor precision of manual alignment and cutting: the perpendicularity deviation of the end face usually exceeds 0.5mm, resulting in uneven cut edges and a scrap rate as high as 5%-8%; 3. Burrs and chipping are easily generated at the cut edge of the glass tube after cutting, requiring separate grinding or flame polishing, which increases the process flow time; 4. For thin glass tubes (outer diameter usually 0.5-5mm, length 1.2-1.8m), due to the small diameter, large length, and fragility, the requirements for the avoidance design of the clamps and the precise control of the cutting parameters are even higher. Although some existing semi-automatic tube cutting machines have achieved mechanical feeding and cutting, they lack coordination between workstations, have long cycle times, and cannot process multiple glass tubes at the same time, thus limiting overall production capacity. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a glass tube cutting machine with a high degree of automation, high processing efficiency and good cutting quality.

[0004] The technical solution adopted by this invention to solve its technical problem is: a glass tube cutting machine, comprising: Main frame; The receiving mechanism includes a receiving frame that can be lifted and lowered within the main frame, a material support plate on the receiving frame, and a material support rack on the material support plate, the material support rack being used to support the glass tube; A sliding seat, which is movably mounted on the main frame in a horizontal direction; A clamp rotation mechanism includes a rotating seat rotatably disposed on the front side of the sliding seat and an aluminum busbar assembly disposed on the rotating seat. The aluminum busbar assembly includes a plurality of needles that can be inserted into a glass tube, and the needles are rotatably disposed on the aluminum busbar assembly. The glue application mechanism includes a powder glue box movably disposed below the clamp rotation mechanism, wherein the powder glue box contains glue powder for applying glue powder to the surface of the needle. The cutting mechanism includes a cutting base disposed at the front end of the main frame and a cutting body disposed above the cutting base. The lower end of the cutting body is provided with a circular blade for cutting glass tubes.

[0005] Preferably, the clamp rotation mechanism further includes a burner mounted on the rotating seat, the air holes of the burner being positioned directly opposite the needle of the aluminum busbar assembly, an ignition needle being provided at one end of the burner, and a baffle plate being provided on the aluminum busbar assembly.

[0006] Preferably, the upper surface of the rotating seat is provided with a cold water tank and a water inlet hole for connecting external cooling water. The rotating seat is covered with a cover plate on the upper side of the cold water tank, and the aluminum busbar assembly is disposed on the upper side of the cover plate.

[0007] Preferably, the aluminum busbar assembly has dovetail grooves on both sides of its bottom. One side of the rotating seat is provided with a fixed clamping block, and the other side is provided with a movable clamping block driven by a clamping cylinder, which is used to cooperate with the dovetail grooves to achieve detachable fixing of the aluminum busbar assembly.

[0008] As a preferred option, it also includes: The feeding mechanism includes a feeding bracket disposed on one side of the main frame, a material support aluminum plate horizontally slidably disposed on the feeding bracket, and alignment plates disposed on both sides of the material support aluminum plate. The upper surface of the material support aluminum plate is provided with a plurality of toothed grooves for supporting the glass tube, and the alignment plates are used to align the ends of the glass tube. The clamping mechanism includes a clamping frame that is vertically and flexibly disposed below the clamping rotation mechanism, and a clamping bar disposed on the top of the clamping frame. The upper surface of the clamping bar is provided with a plurality of toothed grooves for supporting the glass tube. A tightening mechanism, comprising a tightening swing arm rotatably mounted on the top of the sliding seat and a tightening rubber roller mounted on the movable end of the tightening swing arm, wherein the tightening rubber roller is configured to correspond to the clamping bar of the clamping mechanism after the tightening swing arm is flipped. The scraping mechanism includes a scraping funnel that can be raised and lowered and is located directly below the aluminum strip assembly, and two steel brush rollers located at the upper end of the scraping funnel. The two steel brush rollers rotate in opposite directions to clean the needle.

[0009] Preferably, the receiving mechanism consists of two sets, with the aluminum plates of the receiving mechanism and the feeding mechanism arranged alternately. A receiving aluminum strip is horizontally slidable on the receiving frame, and the supporting plate is disposed on the receiving aluminum strip. The supporting plate slides laterally towards the feeding mechanism and towards the receiving mechanism to transfer the glass tube on the supporting aluminum plate to the supporting plate of the receiving mechanism.

[0010] Preferably, the adhesive application mechanism includes a liftable powder adhesive lifting platform, the powder adhesive box is horizontally slidably disposed on the top of the powder adhesive lifting platform, and the powder adhesive lifting platform is provided with a scraper with its lower end extending into the powder adhesive box. The powder adhesive box is used to apply adhesive to the needle head when it slides directly below the aluminum busbar assembly.

[0011] Preferably, the cutting mechanism further includes an air-blowing base that can be lifted and lowered on the cutting base, a lower blade holder located on top of the air-blowing base, and a rotatable cutting blade holder located on the main frame. The upper surface of the lower blade holder has multiple toothed grooves for supporting the glass tube. The air-blowing base has an air-blowing header inside for blowing air into the toothed grooves of the lower blade holder. Each toothed groove of the air-blowing header is provided with an air-blowing pipe. The cutting blade body is vertically slidably located at the front end of the cutting blade holder. The lower end of the cutting blade body has multiple cutting grooves corresponding to the blade holder, and the circular blade is located in the cutting grooves. The front side of the cutting blade body is provided with an aluminum cutting blade for crushing the cut glass tube. The main frame has a discharge funnel on the front side of the cutting base, and a flip plate is hinged at the lower outlet of the discharge funnel.

[0012] Preferably, the system also includes an electrical control box, which is located on the opposite side of the main frame from the feeding mechanism, and is used to control the operation of each mechanism.

[0013] The beneficial effects of this invention are: 1. By cooperating with two sets of receiving and feeding mechanisms, the glass tubes are quickly transferred. Approximately 200 thin glass tubes can be processed at the same time. The time for the needle to rotate the glass tube once is no more than 0.5 seconds (actually up to 0.33 seconds). Compared with the existing semi-automatic tube cutting machine, the efficiency is increased by dozens of times, and the processing cost of a single product is significantly reduced. 2. The clamping method involves inserting a needle into the inner wall of the glass tube and rotating the glass tube synchronously. Combined with a circular cutter, the glass tube is cut while rotating, ensuring uniform force on the circumference of the glass tube. The alignment plate of the feeding mechanism and the baffle plate on the aluminum frame achieve double end alignment (accuracy ±0.1mm), ensuring that the cutting position of each glass tube is accurate and consistent. The perpendicularity deviation of the cut glass tube end face does not exceed 0.2mm, and the roughness Ra of the cutting edge is reduced from the original 3.2μm to below 0.8μm. There are no visible burrs or chipped edges, and the flatness qualification rate reaches over 99.5%. It can be used directly without secondary grinding. 3. The adhesive powder serves as a temporary bonding medium between the needle and the glass tube, and the softening and curing timing of the adhesive powder is precisely controlled through three ignitions: the first ignition preheats the needle and evenly coats it with adhesive, with the thickness of the adhesive layer fluctuating within ±0.03mm; the second ignition ensures that the adhesive powder fully fills the gap after insertion into the tube, and after cooling, it forms a tensile force of 12-18N, ensuring that there is no relative sliding between the glass tube and the needle during the cutting process; the third ignition softens the residual adhesive powder, and with the help of a steel brush roller, more than 98% of the residue on the needle surface can be removed. Compared with the solution of using mechanical grippers or elastic expansion sleeves, this invention has no risk of damage to thin glass tubes (wall thickness of only 0.5mm), and the separation is fast and reliable. 4. The air-blowing base blows compressed air to remove dust from the inner and outer walls of the glass tube before cutting. The impact force of the aluminum cutting blade is finely adjusted (peak force 8-12N) to ensure cutting while preventing the tube opening from cracking. Continuous operation tests show that the scrap rate is controlled within 0.5%, which is far lower than the 5%-8% of manual operation and the 2%-3% of semi-automatic equipment.

[0016] The technical solution of the present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. Example

[0017] like Figures 1 to 8 The glass tube cutting machine shown is mainly used to cut thin glass mother tubes with a length of approximately 1500mm into glass short tubes of different lengths (the length of the cut short tubes can be freely set according to the application scenario), ensuring that the cut is smooth and burr-free. This embodiment can process more than 200 thin glass tubes simultaneously. It includes a main frame 1, a receiving mechanism 2, a feeding mechanism 5, a sliding seat 10, a clamping rotation mechanism 3, a clamping mechanism 6, a tightening mechanism 7, a glue applying mechanism 8, a scraping mechanism 9, a cutting mechanism 4, a discharge funnel 11, and an electrical control box 13.

[0018] The main frame 1 is an integral welded steel structure with adjustable feet at the bottom for supporting and fixing the various functional mechanisms.

[0019] The feeding mechanism 5 is located on the left side of the main frame 1. The feeding mechanism 5 includes a feeding bracket 501, a horizontally sliding aluminum support plate 502 mounted on the feeding bracket 501, and alignment plates 503 on both sides of the aluminum support plate 502. The upper surface of the aluminum support plate 502 has grooves for supporting the thin glass tubes. The feeding bracket 501 and the aluminum support plate 502 are connected by a guide rail, and the aluminum support plate 502 is driven to slide by an independently configured set of cylinders. The two alignment plates 503 are directly driven to slide by two independently configured sets of cylinders.

[0020] The receiving mechanism 2 consists of two sets, referred to as the first receiving mechanism 2 and the second receiving mechanism 2, respectively. Both sets of receiving mechanisms 2 work together to support the glass tube. When the clamping rotating mechanism 3 approaches, the receiving mechanism 2 lowers to avoid interference. Specifically, each set of receiving mechanisms 2 includes a receiving frame 201 that is vertically mounted within the main frame 1, a receiving aluminum strip 204 that slides horizontally on the receiving frame 201, and a support plate 202 mounted on the upper side of the receiving aluminum strip 204. The support plate 202 is provided with a support rack 203 for supporting the glass tube, and the tooth shape of the support rack 203 corresponds one-to-one with the tooth grooves on the support aluminum plate 502. The receiving rack 201 and the receiving aluminum strip 204 are connected by guide rails, and the receiving aluminum strip 204 is driven to slide by an independently configured motor and synchronous belt. Specifically, there are two sets of guide rails. One set is located between the side wall of the receiving rack 201 and the side wall of the receiving aluminum strip 204 and is connected to the synchronous belt, serving as a driving force. The other set is located between the bottom extension of the receiving rack 201 and the bottom of the receiving aluminum strip 204, serving as a support. The receiving rack 201 is driven to rise and fall by a lead screw and an independently configured motor to avoid the rotating clamp rotation mechanism 3 and the glass tube connecting to the feeding mechanism 5. The two sets of receiving mechanisms 2 and the supporting aluminum plates 502 of the feeding mechanism 5 are staggered. Specifically, the supporting aluminum plate 502 is located in the middle, and the two sets of receiving mechanisms 2 are located on its front and rear sides, respectively.

[0021] The sliding seat 10 is movably mounted on the main frame 1 in the horizontal direction. Specifically, the main frame 1 has symmetrical grooves on both sides of the top. The two ends of the sliding seat 10 are driven to move by an independently configured motor through a screw and nut pair in the grooves to realize the step feeding of glass tubes between different workstations.

[0022] The clamp rotation mechanism 3 includes a rotating seat 301 rotatably disposed on the front side of the sliding seat 10, an aluminum strip assembly disposed on the rotating seat 301, a baffle plate 305 disposed on the aluminum strip assembly, and a fire bar 303 disposed on the rotating seat 301. The rotating seat 301 is driven by an independently configured motor and can rotate 0°-180° in the vertical plane. The aluminum busbar assembly includes an aluminum busbar frame and needles 302 rotatably mounted on the aluminum busbar frame. The spacing of the needles 302 is consistent with the tooth pitch of the material support rack 203. Each needle 302 has a smooth surface and can be inserted into the interior of a thin glass tube. The needles 302 adopt a multi-segment structure according to requirements, including, from the front end to the rear end, a conical needle tip, a small-diameter cylindrical section, a frustum-shaped transition section, and a large-diameter cylindrical section. The aluminum busbar frame is equipped with a lead screw for driving the rotation of the needles 302 and an independently configured motor. The rotation speed of the needles 302 can be steplessly adjusted between 0-600 rpm. In this embodiment, the time for the needles 302 to drive the glass tube to rotate one revolution does not exceed 0.5 seconds (i.e., the rotation speed is not less than 120 rpm, actually set to 180 rpm, and the single revolution time is 0.33 seconds). The upper surface of the rotating seat 301 is provided with a cold water tank 306 and a water inlet 307 that connects to external cooling water. The rotating seat 301 is covered with a cover plate 308 on the upper side of the cold water tank 306. The aluminum busbar assembly is located on the upper side of the cover plate 308. The cold water tank 306 contains cooling water. The cooling water can cool the rotating seat 301 when the fire bar 303 heats the needle 302, thus avoiding damage to the power components and sealing rings on the rotating seat 301. Dovetail grooves 309 are provided on both sides of the bottom of the aluminum busbar assembly. A fixed clamping block 310 is provided on one side of the rotating seat 301, and a movable clamping block 312 driven by the clamping cylinder 311 is provided on the other side. This is used to cooperate with the dovetail grooves 309 to achieve detachable fixing of the aluminum busbar assembly. During installation, the dovetail groove 309 is aligned with the fixed clamping block 310 and pushed in. The clamping cylinder 311 pulls the movable clamping block 312 to press the other side of the dovetail groove 309, which can achieve quick clamping and fixing of the aluminum busbar assembly. During disassembly, the clamping cylinder 311 extends to release the assembly, which is convenient for replacing aluminum busbar assemblies of different specifications. The burner 303 is mounted on the rotating base 301 with its vent facing the needle 302 of the aluminum burner assembly. One end of the burner 303 is equipped with an ignition needle 304. The burner 303 is connected to a gas pipeline, and the gas flow rate is controlled at 2.5-3.5L / min. The flame temperature can reach 800-1000℃. The main function of the burner 303 is to heat and soften the adhesive powder coated on the surface of the needle 302.

[0023] The clamping mechanism 6 includes a clamping frame 601 that is vertically and vertically mounted below the clamping rotation mechanism 3 via a linear bearing, and a clamping bar 602 mounted on the top of the clamping frame 601. The upper surface of the clamping bar 602 is provided with a toothed groove for supporting the glass tube. The clamping frame 601 is driven to lift by a lead screw and an independently configured motor.

[0024] The tightening mechanism 7 includes a tightening swing arm 701 rotatably mounted on the top of the sliding seat 10 and a tightening rubber roller 702 mounted on the movable end of the tightening swing arm 701. Both the tightening swing arm 701 and the tightening rubber roller 702 are independently equipped with motors for driving. After the tightening swing arm 701 rotates, the tightening rubber roller 702 is positioned opposite the clamping bar 602 to clamp the end of the glass tube. The rotating and squeezing action of the tightening rubber roller 702 causes the glass tube to move toward the needle 302, allowing the needle 302 to be inserted deeper.

[0025] The adhesive application mechanism 8 includes a powder adhesive lifting platform 801, a powder adhesive box 802, and a scraper 803. The powder adhesive lifting platform 801 is vertically mounted at the rear end of the main frame 1 via two independently configured cylinders. The powder adhesive box 802 is horizontally slidable on top of the powder adhesive lifting platform 801 via guide rails and is driven by an independently configured cylinder. The powder adhesive box 802 can move from the rear end of the main frame 1 to below the aluminum strip assembly. The powder adhesive box 802 contains adhesive powder. The scraper 803 is mounted on the powder adhesive lifting platform 801 and located above the powder adhesive box 802, with its lower end extending into the powder adhesive box 802.

[0026] The scraping mechanism 9 includes a scraping funnel 901 and two steel brush rollers 902. The scraping funnel 901 is raised and lowered directly below the aluminum strip assembly by two independently configured cylinders, so that the powder box 802 can pass between the scraping mechanism 9 and the aluminum strip assembly without causing interference. The two steel brush rollers 902 are set at the upper end of the scraping funnel 901 and are driven to rotate in opposite directions by an independently configured motor. There is a gap between the two steel brush rollers 902 for the needle 302 of the aluminum strip assembly to pass through.

[0027] The cutting mechanism 4 includes a cutting base 401, an air blowing base 404, a lower blade holder 405, a cutting blade holder 406, and a cutting blade body 402. The cutting base 401 is fixed to the front end of the main frame 1. The air blowing base 404 is vertically mounted on the cutting base 401 via two linear bearings and is driven by a lead screw and an independently configured motor. The lower blade holder 405 is located on top of the air blowing base 404. The upper surface of the lower blade holder 405 has grooves for supporting the glass tube. The air blowing base 404 has an air blowing header 407 inside. Each groove of the air blowing header 407 corresponds to an air blowing pipe 408, which is used to blow compressed air (pressure 0.3-0.5MPa) before cutting to remove dust from the inner and outer walls of the glass tube. The cutting blade holder 406 is mounted on the main frame 1 via a flip-up seat. The cutting body 402 is vertically slidably mounted on the front end of the cutting base 406 via a guide rail and is driven to lift by a lead screw and an independently configured motor. The lower end of the cutting body 402 is provided with a cutting groove 409 corresponding to the lower cutting base 405. Each cutting groove 409 is provided with a round blade 403. The front side of the cutting body 402 is provided with an aluminum cutting blade 410 which can be lifted and lowered by two independently configured cylinders. The discharge funnel 11 is set on the main frame 1 and located in front of the cutting base 401. The lower end of the discharge funnel 11 is hinged with a flip plate 12. The discharge funnel 11 can be rotated by a cylinder to control the outlet direction of the discharge funnel 11.

[0028] The electrical control box 13 is located on the opposite side (i.e., the right side) of the main frame 1 and the feeding mechanism 5. It integrates a PLC controller, a touch screen, a servo driver and a frequency converter. The electrical control box 13 is electrically connected to all motors, cylinders, sensors and ignition needles 304, and coordinates the action sequence and rhythm of each mechanism according to a preset program.

[0029] The glass tube cutting machine in this embodiment operates automatically according to the following steps: 1. Place multiple glass tubes on the aluminum support plate 502 and let them fall into the toothed groove. First, use the output end alignment plate 503 to align the ends of the glass tubes, and then use the other side alignment plate 503 to align the ends of the glass tubes. 2. The two sets of receiving mechanisms 2 and the aluminum plate 502 move towards each other. The receiving mechanism 2 moves upward to transfer the glass tube to the rack 203 of the plate 202 and returns to the main frame 1. At the same time, the needle 302 is heated for the first time and the needle 302 is immersed in the adhesive powder so that the adhesive powder adheres to its surface. 3. The baffle plate 305 on the aluminum busbar assembly is aligned with the end of the glass tube again, and then the aluminum busbar assembly is flipped so that the needle 302 is facing the opening of the glass tube. 4. The clamping mechanism 6 moves upward to lift the end of the glass tube, while the tightening roller 702 of the tightening mechanism 7 flips and abuts against the upper side of the glass tube. The forward movement of the aluminum strip assembly allows the needle 302 to be inserted into the glass tube. The second ignition heating causes the adhesive powder to melt and fully fill the gap. After cooling, a temporary bond is formed. The tightening roller 702 rotates and squeezes to move the glass tube toward the needle 302, allowing the needle 302 to be inserted deeper. At the same time, the needle 302 rotates to ensure that the adhesive powder between the needle 302 and the glass tube is uniform. 5. The cutting mechanism 4 flips and resets to form a cutting channel through which the glass tube passes. The sliding seat 10 sends the glass tube to the cutting mechanism 4. The air pipe 408 removes dust. The circular knife 403 feeds in and cuts in. The needle 302 drives the glass tube to rotate to achieve cutting while rotating. The aluminum cutting knife 410 presses down quickly to break the cut glass tube. The finished product falls into the discharge funnel 11. 6. The aluminum strip assembly is reset and flipped so that the needle 302 is facing the scraping mechanism 9. The third ignition heating softens the residual adhesive powder on the surface of the needle 302. The steel brush roller 902 rotates in opposite directions to brush away the residue and glass tube.
