Description

Technical Field

[0001] The invention relates to the technical field of glass bottle firing, in particular to a bottle bottom firing device for a tube-type glass bottle. Background Art

[0002] Glass bottles are widely used in the fields of food, medicine, chemical laboratory storage, etc. due to their good transparency, strong hardness and low cost. However, the bottom of the glass bottles directly produced by the existing glass bottle manufacturing process is relatively thin, and the internal pressure of the glass bottles is low, which makes them easy to burst, causing damage to the glass bottles during use and having a certain impact on the quality of the glass bottles. Therefore, after the glass bottles are produced, the bottom of the bottle is often fired to obtain a thicker bottom.

[0003] Most existing methods for thickening bottle bottoms involve heating the bottle bottom to a suitable temperature, then squeezing the bottle bottom with a metal block to achieve the purpose of thickening, and coordinating with rotation to maintain the shape of the bottle body. The existing rotating structure often drives the bottle body to rotate, and then drives the metal block to rotate through the bottle body. The two are prone to relative rotation, causing the bottle body to twist. At the same time, when the bottle bottom is burned, the metal block in contact with it is in contact with the flame for a long time. The incompletely burned flame forms carbon deposits on its side, affecting its inherent size, thereby affecting the accuracy of the bottle bottom firing. Therefore, we propose a bottle bottom firing equipment for tube-type glass bottles. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a bottom firing device for a tube-shaped glass bottle, comprising:

[0005] a base plate, and support blocks symmetrically arranged on top of the base plate;

[0006] A firing device having a flame-jet structure for heating the bottom of the tube glass bottle to a suitable temperature;

[0007] The top of the bottom plate is fixedly connected to the bottoms of the two support blocks, and the firing device is fixedly connected to a side of the support block away from the bottom plate;

[0008] Wherein, the firing device comprises:

[0009] a flamethrower capable of emitting a high-temperature flame suitable for burning, and a base disposed on a side of the flamethrower close to the base plate;

[0010] A fixing mechanism for fixing the bottle mouth end of the tube glass bottle;

[0011] A bottom block, the side of which close to the fixing mechanism is configured as an arc surface and adapted to the bottom of the tube glass bottle;

[0012] A transmission mechanism, which is used to drive the fixing mechanism and the bottom block to rotate synchronously, and to drive the bottom block to move horizontally;

[0013] A cleaning mechanism having a scraping structure for cleaning carbon deposits on the surface of the bottom block, wherein a support plate is provided on the outside of the cleaning mechanism;

[0014] One end of the flamethrower close to the bottom plate passes through the base and is fixed to the inside of the base, and the side of the base away from the flamethrower is fixedly connected to the top of the bottom plate, the side of the fixing mechanism away from the bottom block is fixedly connected to the output end of the transmission mechanism, and the side of the bottom block away from the fixing mechanism is fixedly connected to the other output end of the transmission mechanism, the side of the cleaning mechanism away from the bottom block is fixedly connected to the support plate, the bottom of the support plate is fixedly connected to the top of the bottom plate, and the output end of the transmission mechanism passes through the support plate and is slidably connected to the inner wall of the support plate, and the side of the support block away from the bottom plate is fixedly connected to the surface of the transmission mechanism, the bottle mouth end of the tube glass bottle is inserted into the fixing mechanism, and after adjusting the fixing depth, the bottom of the bottle is directly above the flamethrower, the flamethrower is started, and the bottom of the bottle is heated to a suitable temperature. At the same time, the transmission mechanism drives the fixing mechanism and the bottom block to rotate synchronously. The flamethrower continues to spray fire, continuously heating the bottom of the bottle to prevent it from solidifying. At this time, the peripheral side of the bottom block is in contact with the flame, and the incompletely burned flame forms carbon deposits on the side of the bottom block, while the contact position between the bottom block and the bottom of the bottle is not easy to produce carbon deposits. The transmission mechanism drives the bottom block to approach the bottom of the bottle and squeeze it, thereby thickening the bottom of the bottle and completing the firing of the bottom of the bottle. The side of the bottom block close to the fixing mechanism is set to an arc surface and adapts to the bottom of the bottle, so that the required depression of the bottle bottom is obtained after firing, making the bottle body more stable. Since the two output ends of the transmission mechanism synchronously drive the bottom block and the fixing mechanism to rotate, the bottle body fixed by the fixing mechanism and the bottle bottom in contact with the bottom block always maintain synchronous movement, and no relative rotation will occur. Compared with the rotation of the bottom block driven by the abutment between the bottle body and the bottom block, it can better avoid torsion between the bottle body and the bottle bottom, thereby avoiding affecting the use of the glass bottle.

[0015] Furthermore, a correction cylinder is provided above the bottom plate, and the correction cylinder is provided on the side surface of the bottom block, and the surface of the correction cylinder is in contact with the outermost circle of the bottle bottom.

The ends of the two springs away from each other are respectively fixedly connected to the inner walls of the two sides of the groove plate, and the ends of the two springs close to each other are fixedly connected to the surface of the connecting column. The cylindrical surface of the correction cylinder first contacts with the bottle body. After contact, the correction cylinder and the bottle body are squeezed, and the correction cylinder is The cylinder moves to adapt to the diameter of the bottle body, driving the groove plate and the slide rod to move, and the spring is squeezed. Under the condition that its cylindrical surface fits the bottle body, the surface of the correction cylinder that adapts to the outer ring of the bottle bottom is in parallel contact with the outer ring of the bottle bottom, thereby completing the rounding of the outer ring of the bottle bottom. A displaceable correction cylinder is provided, and the position of the correction cylinder can be adaptively adjusted according to the diameter of the bottle body, so that the rounding of the bottom of glass bottles with different diameters can be completed.

The rubber strips are made of rubber material and are soft. They will not cause bumps when in contact with the bottle body and can quickly approach the bottle body, thereby accelerating the fixing speed and improving efficiency.

[0024] The present invention has the beneficial effects:

[0025] 1. The present invention provides a firing device, and the side of the bottom block close to the fixing mechanism is set as an arc surface and adapted to the bottle bottom, so that the desired depression of the bottle bottom is obtained after firing, making the bottle body more stable. Since the two output ends of the transmission mechanism synchronously drive the bottom block and the fixing mechanism to rotate, the bottle body fixed by the fixing mechanism and the bottle bottom in contact with the bottom block always maintain synchronous movement without relative rotation. Compared with the method of driving the rotation of the bottom block by the abutment between the bottle body and the bottom block, it can better avoid the torsion between the bottle body and the bottle bottom, and avoid affecting the use of the glass bottle.

[0026] 2. The present invention provides a correction cylinder.

The correction cylinder is provided. The correction cylinder contacts the outermost circle of the bottle bottom along with the inner cylinder.

To improve work quality and further protect users, the correction cylinder is set to be offset. The position of the correction cylinder can be adaptively adjusted according to the diameter of the bottle body, and the bottom of glass bottles with different diameters can be rounded. The cylindrical surface of the correction cylinder first contacts the bottle body, so that the surface of the correction cylinder adapted to the outer ring of the bottle bottom is in parallel contact with the outer ring of the bottle bottom, and no tilting or squeezing is caused on the heated and soft part of the bottle bottom, thereby ensuring the verticality of the bottle bottom. The deformed spring can drive the slide rod, groove plate and correction cylinder to return to their original position after rounding, so as to facilitate the next operation.

[0027] 3. The present invention provides a fixing mechanism. When a glass bottle is inserted, the bottle mouth enters the gap between the center rod and the barrel and contacts the positioning plate. The positioning plate is deformed and slightly clamps the bottle body, achieving a pre-positioning effect. This can free the operator's hands before the first telescopic rod is activated, making it easier for the operator to perform other operations. The clamping of the three positioning plates can position the bottle body concentric with the center column, facilitating subsequent fixation. The curved positioning plate can be pre-positioned regardless of the length of the inserted bottle body, thereby adjusting the position of the bottle bottom and the flamethrower, so that the bottom of the tube glass bottle of various lengths can be directly above the flamethrower, avoiding excessive heating of the part other than the bottle bottom and preventing the bottle body from bending under the action of gravity. The provision of the rubber strip can significantly increase the friction between the fixing plate and the bottle body, preventing the bottle body and the fixing plate from rotating relative to each other or even slipping. The rubber strip is made of soft rubber and will not cause any bumps when in contact with the bottle body. It can quickly approach the bottle body, speeding up the fixing speed and improving efficiency. The symmetrical V-shaped rubber strip can significantly increase the resistance to relative rotation between the bottle body and the fixing plate, thereby achieving a better fixing effect.

[0028] 4. The present invention provides a cleaning mechanism, and the bottom block contacts the wedge-shaped side of the cleaning block, thereby scraping the surface of the bottom block, thereby removing carbon deposits on the surface of the bottom block, avoiding the increase in the thickness of the bottom block caused by carbon deposits, and maintaining the effect of the bottom block. At the same time, the surface of the bottom block contacts the scraper to further clean the carbon deposits. Since the three groups of cleaning blocks close to the side of the bottom block together form a circular ring, the scraping of the entire bottom block surface can be completed during short-distance movement, which can better process the carbon deposit on the surface of the bottom block. The side of the scraper away from the cleaning block is inclined in the same direction as the output end of the motor, that is, the inclination direction of the scraper is opposite to the rotation direction of the bottom block, forming an obtuse angle, so as to oblique scraping, which can better clean the carbon deposits, and the obtuse angle can avoid the accumulation of carbon deposits in the scraper gap, thereby avoiding the gap between adjacent scrapers from being blocked, and can maintain the scraping effect during long-term use.

[0044] Among them, the firing device 3 includes:

[0045] a flamethrower 31 capable of spraying a high-temperature flame suitable for burning, and a base 4 disposed on a side of the flamethrower 31 close to the bottom plate 1;

[0046] A fixing mechanism 32, which is used to fix the bottle mouth end of the tube glass bottle;

[0047] A bottom block 33, the side of which close to the fixing mechanism 32 is configured as an arc surface and adapted to the bottom of the tube glass bottle;

The transmission mechanism 34 drives the bottom block 33 to approach the bottle bottom and squeeze it, thereby thickening the bottle bottom and completing the firing of the bottle bottom. The side of the bottom block 33 close to the fixing mechanism 32 is set as an arc surface and adapts to the bottle bottom, so that the required depression of the bottle bottom is obtained after firing, making the bottle body more stable. Since the two output ends of the transmission mechanism 34 synchronously drive the bottom block 33 and the fixing mechanism 32 to rotate, the bottle body fixed by the fixing mechanism 32 and the bottle bottom in contact with the bottom block 33 always maintain synchronous motion without relative rotation.

An inner cylinder 37 is provided inside the correction cylinder 36. The end of the inner cylinder 37 away from the flamethrower 31 is also fixedly connected to the transmission assembly 38. After the bottle bottom contacts the bottom block 33 and before extrusion occurs, the transmission assembly 38 drives the inner cylinder 37 to rotate, driving the correction cylinder 36 to rotate. The correction cylinder 36 contacts the bottle body, and as As the bottle body rotates, the correction cylinder 36 and the bottle body rotate relative to each other, thereby correcting the bottle body to ensure the verticality of the bottle body and avoid bending of the heated bottle bottom under the influence of gravity. The correction cylinder 36 is set, and the correction cylinder 36 contacts the outermost circle of the bottle bottom along with the inner cylinder 37. Since the surface of the correction cylinder 36 is arranged in contact with the outer circle of the bottle bottom, the bottle bottom can be rounded into a shape similar to a fillet, thereby avoiding a sharp outermost circle of the bottle bottom, thereby protecting the user, and can also remove burrs before firing, ensure the processing quality of the glass bottle, and further protect the user.

The correction cylinder 36 moves to adapt to the diameter of the bottle body, driving the groove plate 39 and the slide bar 310 to move, and the spring 311 is squeezed. Under the condition that its cylindrical surface fits the bottle body, the surface of the correction cylinder 36 that adapts to the outer ring of the bottle bottom is in parallel contact with the outer ring of the bottle bottom, thereby completing the rounding of the outer ring of the bottle bottom. The offset correction cylinder 36 is provided, and the position of the correction cylinder 36 can be adaptively adjusted according to the diameter of the bottle body, so that the rounding of the bottom of glass bottles with different diameters can be completed. The cylindrical surface of the correction cylinder 36 first contacts the bottle body, so that the surface of the correction cylinder 36 that adapts to the outer ring of the bottle bottom is in parallel contact with the outer ring of the bottle bottom, and will not cause tilting and squeezing of the heated and soft part of the bottle bottom, thereby ensuring the verticality of the bottle bottom, and the deformed spring 311 can drive the slide bar 310, the groove plate 39, and the correction cylinder 36 to return to their original position after rounding, facilitating the next operation.

[0054] Example 2, please refer to Figures 1-9 When the bottle body is inserted into the cylinder 322 and the first telescopic rod 325 is started, the first telescopic rod 325 drives the fixing plate 323 to move closer to the bottle body, and the fixing plate 323 of the first telescopic rod 325 is locked.

[0055] The fixing plate 323 is fixedly connected to a limiting column 326 on one side close to the first telescopic rod 325, and two limiting columns 326 are symmetrically arranged. The ends of the two limiting columns 326 away from the fixing plate 323 pass through the mounting plate 324 and are slidably connected to the inner wall of the mounting plate 324. The symmetrical limiting columns 326 limit the fixing plate 323 to ensure that the fixing plate 323 is parallel to the bottle body, thereby ensuring the fixing effect.

[0056] The fixing plate 323 is fixedly connected to a side away from the first telescopic rod 325 with a rubber strip 327, and the rubber strip 327 is symmetrically arranged in two groups, each group of rubber strips 327 is provided with a number of rubber strips 327, and the rubber strips 327 are arranged in a V shape. The provision of the rubber strips 327 can greatly increase the friction between the fixing plate 323 and the bottle body, thereby preventing the bottle body and the fixing plate 323 from relative rotation or even slipping. The rubber strips 327 are made of rubber and are soft. They will not cause bumps when in contact with the bottle body and can quickly approach the bottle body, speeding up the fixing speed and improving the efficiency. The symmetrical V-shaped rubber strips 327 can greatly increase the resistance to relative rotation between the bottle body and the fixing plate 323, thereby achieving a better fixing effect.

[0057] The space between adjacent fixing plates 323 is provided with a positioning plate 328, and the positioning plate 328 is fixedly connected to the inner wall of the cylinder 322. The positioning plate 328 is bent inside the cylinder 322, and the end of the positioning plate 328 away from the cylinder 322 is against the surface of the center rod 321. When the glass bottle is inserted, the bottle mouth enters the space between the center rod 321 and the cylinder 322 and contacts the positioning plate 328. The positioning plate 328 is deformed, slightly clamping the bottle body, playing a pre-positioning effect, and can be inserted into the first extension Before the retraction rod 325 is started, the operator's hands are freed, making it easier for the operator to perform other operations. The clamping of the three positioning plates 328 can position the bottle body concentric with the center column, which is convenient for subsequent fixation. The curved positioning plate 328 can be pre-positioned no matter how long the bottle body is inserted, so as to adjust the position of the bottle bottom and the flamethrower 31, so that the bottom of the tube glass bottle of various lengths can be directly above the flamethrower 31, avoiding overheating of the part other than the bottle bottom and preventing the bottle body from bending under the action of gravity.

[0058] The transmission mechanism 34 includes a housing 341. The sides of the two support blocks 2 away from the bottom plate 1 are fixedly connected to the housing 341. The inner wall of the housing 341 near the center rod 321 is fixedly connected to a motor 342. The output end of the motor 342 is fixedly connected to the end of the center rod 321 away from the bottom block 33, and the surface of the center rod 321 is rotatably connected to the inner wall of the housing 341. Connecting rods 344 are symmetrically arranged at the interval between the two housings 341. The ends of the two connecting rods 344 away from each other both penetrate the housing 341 and are rotatably connected to the inner wall of the housing 341. The connecting rod 344 away from the shell 341 also passes through the sleeve 384 and is slidably connected to the inner wall of the sleeve 384. The ends of the two connecting rods 344 close to each other are fixedly connected. The surfaces of the two connecting rods 344 located inside the shell 341 are both transmission-connected with the conveyor belt 343, and the end of the conveyor belt 343 close to the motor 342 away from the connecting rod 344 is transmission-connected to the surface of the center rod 321. The end of the conveyor belt 343 away from the motor 342 away from the connecting rod 344 is transmission-connected to the rotating shaft 345, and the end of the rotating shaft 345 away from the motor 342 is transmission-connected to the shell 341. The inner wall of the housing 341 is rotatably connected, and one end of the rotating shaft 345 close to the motor 342 extends to the outside of the housing 341 and is rotatably connected to the inner wall of the housing 341. The end of the rotating shaft 345 located outside the housing 341 is fixedly connected to the second telescopic rod 346. The end of the second telescopic rod 346 away from the rotating shaft 345 is fixedly connected to the side of the bottom block 33 away from the center rod 321, and the second telescopic rod 346 and the inner wall of the support plate 5 are limited and rotated. The motor 342 is started, and the output end of the motor 342 drives the center rod 321 and the cylinder 322 to rotate, thereby driving the second telescopic rod 346 fixed on the housing 341. The tube glass bottle inside it rotates, and at the same time, drives the conveyor belt 343 to transmit, drives the two connecting rods 344 to rotate, thereby driving another conveyor belt 343 to transmit, and then drives the rotating shaft 345 and the second telescopic rod 346 to rotate synchronously, and finally drives the center rod 321 and the bottom block 33 to rotate synchronously, that is, the bottle body and the bottle bottom rotate synchronously, avoiding relative rotation between the two when squeezing and thickening the bottle bottom, ensuring that the bottle bottom does not twist. The second telescopic rod 346 extends, driving the bottom block 33 to move, thereby squeezing the bottle bottom, making the bottle bottom thicker, and completing the firing of the bottle bottom of the tube glass bottle.

[0059] The cleaning mechanism 35 includes a cleaning cylinder 351, which is arranged outside the second telescopic rod 346 and is fixedly connected to the side of the support plate 5 close to the bottom block 33. The inner wall of the cleaning cylinder 351 is fixedly connected to a cleaning block 352. The side of the cleaning block 352 away from the inner wall of the cleaning cylinder 351 is adapted to the bottom block 33, and the cleaning block 352 is wedge-shaped on the side close to the bottom block 33. The cleaning blocks 352 are provided in three groups, and the three groups of cleaning blocks 352 are staggered, and the three groups of cleaning blocks 352 are close to the bottom block 3 3 together form a circular ring, and each group of cleaning blocks 352 is evenly distributed along the circumference of the cleaning cylinder 351. The cleaning block 352 is fixedly connected to the side of the cleaning cylinder 351 away from the cleaning cylinder 351 with a scraper 353. The scraper 353 is evenly distributed on the side of the cleaning block 352 away from the cleaning cylinder 351, and the side of the scraper 353 away from the cleaning block 352 is tilted in the same direction as the output end of the motor 342. After the firing is completed, the second telescopic rod 346 is started again, and the second telescopic rod 346 drives the bottom block 33 to rotate. As the bottom block 33 enters the interior of the cleaning cylinder 351, the bottom block 33 contacts the wedge-shaped side of the cleaning block 352, thereby scraping the surface of the bottom block 33, thereby removing the carbon deposits on the surface of the bottom block 33, avoiding the increase in the thickness of the bottom block 33 caused by the carbon deposits, and maintaining the effect of the bottom block 33. At the same time, the surface of the bottom block 33 contacts the scraper 353 to further clean the carbon deposits. Since the three groups of cleaning blocks 352 are close to the side of the bottom block 33 together to form a circular ring, the scraping of the entire surface of the bottom block 33 can be completed during the short-distance movement. , which can better process the carbon deposit on the surface of the bottom block 33. The scraper 353 is arranged to be tilted in the same direction as the output end of the motor 342 on the side away from the cleaning block 352, that is, the tilt direction of the scraper 353 is opposite to the rotation direction of the bottom block 33, forming an obtuse angle, so that the inclined scraping can better clean the carbon deposits, and the obtuse angle can prevent the carbon deposits from accumulating in the intervals between the scrapers 353, thereby preventing the intervals between adjacent scrapers 353 from being blocked, and can maintain the scraping effect during long-term use.

[0060] When the bottle body is in use, the bottle body is inserted into the barrel 322, the bottle mouth enters the gap between the center rod 321 and the barrel 322, and contacts the positioning plate 328. The positioning plate 328 is deformed, and the bottle body is slightly clamped, which plays a pre-positioning effect. After adjusting the positioning depth, the bottle bottom is just above the flame spray gun 31, and the first telescopic rod 325 is started. The first telescopic rod 325 drives the fixing plate 323 to approach the bottle body, and the three first telescopic rods 325 respectively drive the three fixing plates 323 to approach the bottle body, thereby completing the fixation of the bottle body, and starting the motor 342. The output end of the motor 342 drives the center rod 321 and the barrel 322 to rotate, thereby driving the tube glass bottle fixed therein to rotate, and at the same time, drives the conveyor belt 343 to drive, drives the two connecting rods 344 to rotate, thereby driving the other conveyor belt 343 to drive, and then drives the rotating shaft 345 and the second telescopic rod 346 to rotate synchronously, and finally drives the center rod 321 and the bottom block 33 to rotate synchronously, and then starts the flame spray gun 31 to add the bottle bottom. When the bottle is heated to a suitable temperature, the second telescopic rod 346 extends, driving the bottom block 33 to move. After the bottle bottom contacts the bottom block 33 and before the extrusion occurs, the rotating arm 382 is driven. The rotating arm 382 drives the connecting column 381, the inner cylinder 37, the sliding rod 310, the groove plate 39, and the correction cylinder 36 in sequence, rotating with the column 383 as the fulcrum, thereby approaching the bottle body. The cylindrical surface of the correction cylinder 36 first contacts the bottle body. After the contact, the correction cylinder 36 and the bottle body are squeezed, and the correction cylinder 36 adapts to the diameter of the bottle body. The spring 311 is squeezed and the groove plate 39 and the slide bar 310 are moved. The spring 311 is squeezed. Under the condition that its cylindrical surface fits the bottle body, the correction cylinder 36 is adapted to the surface of the outer ring of the bottle bottom and is in parallel contact with the outer ring of the bottle bottom. As the bottle body rotates, the correction cylinder 36 and the bottle body rotate relative to each other, thereby correcting the bottle body. The bottom block 33 approaches the bottle bottom and squeezes it. The flamethrower 31 continues to spray fire and continuously heats the bottle bottom to prevent it from solidifying. After a period of time, the bottle bottom becomes thicker and the firing of the bottle bottom is completed.

[0061] After cleaning is completed, since the peripheral side of the bottom block 33 is in contact with the flame, the incompletely burned flame forms carbon deposits on the side of the bottom block 33, while the contact position between the bottom block 33 and the bottom of the bottle is not prone to carbon deposits. The second telescopic rod 346 is started again, and the second telescopic rod 346 drives the bottom block 33 to rotate and enter the cleaning cylinder 351. The bottom block 33 contacts the wedge-shaped side of the cleaning block 352, thereby scraping the surface of the bottom block 33, thereby removing the carbon deposits on the surface of the bottom block 33. At the same time, the surface of the bottom block 33 contacts the scraper 353 to further clean the carbon deposits.
