Description

Technical Field

[0001] This utility model relates to the field of glass product manufacturing technology, specifically to a bottle-making machine that can conveniently and quickly change the gas path of the mouth mold. Background Technology

[0002] Mouth molds are one of the molds used in modern automated production lines. With the development of technology, automated production lines are becoming increasingly common. In order to improve processing efficiency, multiple processing devices are often deployed simultaneously during the processing of automated equipment. Among them, in the use of bottle-making machines, mouth molds need to be changed for different products in order to continue processing.

[0003] The bottle-making machine includes a fixed support, a tilting mechanism, and a die clamping mechanism. The tilting mechanism is mounted on the fixed support, which has an air inlet. The tilting mechanism can rotate along the axial direction of the fixed support, causing the die clamping mechanism to tilt to the left and right sides of the fixed support's axial direction. An exhaust valve is connected to the tilting mechanism, and a high-pressure air passage is connected to the exhaust valve. After the bottle-making process is completed, the tilting mechanism tilts the die clamping mechanism to the forming side, at which point the high-pressure air passage connects to the air inlet. Currently, the method for changing the die on the bottle-making machine is to stop the machine. With the die on the forming side of the bottle-making machine and the high-pressure air passage connected to the air inlet, high-pressure gas is controlled by a valve box to enter the high-pressure air passage of the tilting mechanism. This high-pressure gas then enters the die clamping mechanism, causing the mounting arms on both sides of the die clamping mechanism to open and loosen the clamp on the die, allowing for die replacement.

[0004] In actual use, the bottle-making machine's flipping mechanism rotates back and forth during operation. In the initial state of the bottle-making process, the die clamp on the flipping mechanism is located on the initial mold side. At this time, the high-pressure air passage in the flipping mechanism is not connected to the air inlet on the fixed bracket. Only when the bottle-making process is completed, i.e., when the die clamp on the flipping mechanism is located on the forming side, can the airflow passage in the flipping mechanism connect with the air inlet on the bottle-making machine housing. After pushing the jaw clamp mechanism to open, the airflow is discharged through the one-way throttle valve on the flipping mechanism. Therefore, the jaw clamp mechanism can only open when the flipping mechanism is located on the forming side. The die clamping position is relatively far, making it difficult for workers to operate, thus affecting the changeover efficiency. Utility Model Content

[0005] This application provides a bottle-making machine that can conveniently and quickly change the gas path of the die, which can solve the technical problems of existing technologies where the die can only be changed on the forming side, making it inconvenient for operators to change the die and resulting in low replacement efficiency.

[0007] A fixed bracket is provided with an air inlet and an air outlet, the air inlet being used to connect to a first air supply device;

[0008] A flipping mechanism is provided on the fixed support. The flipping mechanism has a high-pressure air passage inside, and during the flipping process, the high-pressure air passage can be selectively connected to the air inlet and the air outlet. The flipping mechanism is provided with a die clamping mechanism that is connected to the high-pressure air passage.

[0009] In addition, a three-way ball valve, wherein the first valve port of the three-way ball valve is connected to the exhaust port through an air intake pipe, the second valve port of the three-way ball valve is connected to a one-way exhaust valve, and the third valve port of the three-way ball valve is used to connect to a second air supply device.

[0010] In one embodiment, the flipping mechanism includes:

[0011] The jaws flipping shaft has two ends rotatably mounted on the fixed bracket along its length. The high-pressure air passage is coaxially opened on the jaws flipping shaft. The jaws flipping shaft has an air intake channel that communicates with the high-pressure air passage. During rotation, the air intake channel can selectively communicate with the air inlet and the air outlet. The jaw clamping mechanism is fixed on the jaws flipping shaft.

[0012] And a flipping drive, which is connected to the jaw flipping shaft and is used to drive the jaw flipping shaft to rotate along its own axis.

[0013] In one embodiment, the flipping drive includes:

[0014] Driven gear, the driven gear being fixed on the jaw clamp tilting shaft;

[0015] In addition, a rotary motor is fixed on the fixed bracket, and a drive gear is coaxially connected to the drive shaft of the rotary motor, the drive gear meshing with the driven gear.

[0016] In one embodiment, the two ends of the jaw clamp's flipping shaft along its length are rotatably connected to the fixed bracket via rotating bearings.

[0017] In one embodiment, the die clamping mechanism includes:

[0018] The first clamp is slidably mounted on the jaw flipping shaft along the length direction of the jaw flipping shaft via a first pneumatic connector, and the pneumatic connector is connected to the high-pressure air passage.

[0019] And, a second clamp, the second clamp being slidably mounted on the jaw flipping shaft along the length direction of the jaw flipping shaft via a second pneumatic connector, the second pneumatic connector being connected to the high-pressure air passage, and a jaw clamping station being formed between the second clamp and the first clamp.

[0020] In one embodiment, the first pneumatic connector includes:

[0021] The first reciprocating cylinder is mounted on the jaws tilting shaft. The jaws tilting shaft has an air supply channel. The two ends of the air supply channel in the length direction are respectively connected to the first reciprocating cylinder and the high-pressure air channel. The telescopic end of the first reciprocating cylinder is connected to the first clamp.

[0022] In one embodiment, the second pneumatic connector includes:

[0023] The second reciprocating cylinder is mounted on the jaws tilting shaft. The jaws tilting shaft has an air supply channel. The two ends of the air supply channel in the length direction are respectively connected to the second reciprocating cylinder and the high-pressure air channel. The telescopic end of the second reciprocating cylinder is connected to the second clamp.

[0024] In one embodiment, a bottle-making machine capable of convenient and quick changing of the nozzle gas path further includes:

One buffer bushing is connected to the first clamp via a movable buffer component, and the other buffer bushing is connected to the second clamp via a movable buffer component. The buffer bushings are disposed at the ends of the first clamp and the second clamp away from the die clamping station.

[0026] In one embodiment, the movable buffer is configured as a telescopic spring.

[0027] In one embodiment, a stroke nut is provided at the end of the buffer bushing away from the die clamping station.

[0028] The beneficial effects of the technical solutions provided in this application include:

[0029] By connecting an additional air intake pipe to the exhaust port of the flipping mechanism and connecting it to the air intake pipe using a three-way ball valve, the second valve port of the three-way ball valve, which is connected to the one-way exhaust valve, is opened when the flipping mechanism is working normally, allowing the exhaust port of the flipping mechanism to exhaust normally. When it is necessary to replace the die on the flipping mechanism, after the flipping mechanism has finished venting and stopped working, the first and third valve ports are opened. At this time, the high-pressure air passage in the flipping mechanism is connected to the exhaust port, and the third valve port of the three-way ball valve can introduce the high-pressure gas from the second air supply device into the high-pressure air passage through the air intake pipe connected to the first valve port, providing additional high-pressure gas to the die clamping mechanism. This allows the die clamping mechanism to still be opened when the flipping mechanism is on the initial molding side, solving the problem in the prior art where the die can only be replaced on the molding side, making it inconvenient for operators to replace the die.

[0036] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0037] This application provides a bottle-making machine that allows for convenient and quick changing of the die gas path, which solves the problems of existing technologies where the die can only be changed on the forming side, making it inconvenient for operators to change the die and resulting in low changing efficiency.

[0038] Reference Figures 1-3 This application discloses a bottle-making machine capable of convenient and quick changing of the mouth mold gas path, including a fixed support 1, a flipping mechanism, and a three-way ball valve 3. The fixed support 1 has an air inlet 11 and an air outlet 12, and the air inlet 11 is connected to a first gas supply device. The flipping mechanism is mounted on the fixed support 1, and a high-pressure gas channel 21 is provided inside the flipping mechanism. A mouth mold clamping mechanism connected to the high-pressure gas channel 21 is movably mounted on the flipping mechanism. During the flipping process, the high-pressure gas channel 21 can be selectively connected to either the air inlet 11 or the air outlet 12. The three-way ball valve 3 has three valve ports, wherein the first valve port is connected to the air outlet 12 through an air intake pipe 31, the second valve port is connected to a one-way exhaust valve 32, and the third valve port is used to connect to a second gas supply device 33.

[0039] When the flipping mechanism drives the die clamping device to flip, the three-way ball valve 3 is closed, and the bottle making machine operates normally. There are two scenarios when the die needs to be replaced. When the die clamping mechanism is on the initial mold side, the high-pressure air passage 21 on the flipping mechanism is connected to the exhaust port 12. At this time, the equipment stops, keeping the second valve port of the three-way ball valve 3 closed (i.e., closing the one-way exhaust valve 32), and opening the first and third valve ports. This allows the second air supply device 33 to supply high-pressure gas through the air intake pipe 31 to the high-pressure air passage 21 on the flipping mechanism. The high-pressure gas enters the die clamping device, causing it to open and releasing the die clamp for replacement. After the die replacement is completed... Close the first and third valve ports and open the second valve port to exhaust the gas from the flipping mechanism. When the die clamping mechanism is located on the forming side, the high-pressure air passage 21 on the flipping mechanism is connected to the air inlet 11. At this time, the equipment stops, the three-way ball valve 3 is kept closed, and the first air supply device is opened to supply high-pressure gas to the high-pressure air passage 21 through the air inlet 11, so that the die clamping device opens and the die clamping is released for replacement. After the die replacement is completed, the second valve port in the three-way ball valve 3 is opened, and the flipping mechanism is exhausted through the one-way exhaust valve 32.

[0040] The flipping mechanism includes a jaw flipping shaft 2 and a flipping drive component. The jaw flipping shaft 2 has fixed ends extending from both ends along its length. The fixed ends of the jaw flipping shaft 2 are rotatably mounted on a fixed bracket 1 via a rotating bearing 22. A high-pressure air passage 21 is coaxially opened inside the jaw flipping shaft 2, and the air outlet of the high-pressure air passage 21 is opened at the end of the jaw flipping shaft 2 that abuts against the fixed bracket 1. This allows the air outlet of the high-pressure air passage 21 to rotate to a state where it is connected to the air inlet 11 and the air outlet 12 respectively as the jaw flipping shaft 2 rotates. A jaw clamping mechanism is installed on the jaw flipping shaft 2 so that the jaw flipping shaft 2 can drive the jaw clamping mechanism to flip left and right on the fixed bracket 1 during rotation.

[0041] The tilting drive includes a driven gear 23 and a rotary motor 5, see reference. Figure 1 The driven gear 23 is sleeved on the surface of the jaw flipping shaft 2, and the driven paper wheel is fixedly connected to the jaw flipping shaft 2. The rotary motor 5 is fixed to the fixed bracket 1 by bolts. The output shaft of the rotary motor 5 is coaxially connected to the drive gear 51, which meshes with the driven gear 23. When the rotary motor 5 is turned on, the driven gear 23 can be driven to rotate through the drive gear 51, thereby causing the jaw flipping shaft 2 to rotate along its own axis, so that the jaw clamping mechanism on the jaw flipping shaft 2 can flip left and right.

[0042] Reference Figure 1 and Figure 4 The die clamping mechanism includes a first clamp 4 and a second clamp 41. The first clamp 4 is slidably mounted on the jaw tilting shaft 2 along its length via a first pneumatic connector. The second clamp 41 is slidably mounted on the jaw tilting shaft 2 along its length via a second pneumatic connector. A die clamping station is formed between the first clamp 4 and the second clamp 41. The first pneumatic connector is used to push the first clamp 4 toward or away from the die clamping station, and the second pneumatic connector is used to push the second clamp 41 toward or away from the die clamping station. Both the first and second pneumatic connectors are connected to a high-pressure air passage 21. When high-pressure gas is introduced into the first and second pneumatic connectors through the high-pressure air passage 21, the first pneumatic connector can drive the first clamp 4 to move away from the end of the second clamp 41, and the second pneumatic connector can drive the second clamp 41 to move away from the end of the first clamp 4, thereby releasing the clamping of the die in the clamping station.

[0043] In one embodiment of this application, the first pneumatic connector is specifically a first reciprocating cylinder 42. The first reciprocating cylinder 42 is fixed to the jaw clamp tilting shaft 2 by bolts. The telescopic end of the first reciprocating cylinder 42 is connected to the first clamp 4. The jaw clamp tilting shaft 2 is also provided with an air supply channel 421, and the two ends of the air supply channel 421 in the length direction are respectively connected to the first reciprocating cylinder 42 and the high-pressure air passage 21. The second pneumatic connector is specifically a second reciprocating cylinder 44. The second reciprocating cylinder 44 is also fixed to the jaw clamp tilting shaft 2 by bolts. The telescopic end of the second reciprocating cylinder 44 is connected to the second clamp 41. The jaw clamp tilting shaft 2 is also provided with an air supply channel 421, and the two ends of the air supply channel 421 in the length direction are respectively connected to the second reciprocating cylinder 44 and the high-pressure air passage 21. When high-pressure gas enters the first reciprocating cylinder 42 and the second reciprocating cylinder 44 through the high-pressure gas passage 21 and the gas supply passage 421, the telescopic ends of the first reciprocating cylinder 42 and the second reciprocating cylinder 44 push the first clamp 4 and the second clamp 41 away from the die clamping position to release the die clamping and facilitate die replacement by the operator. After die replacement is completed, the second valve body of the three-way ball valve 3 is opened, and the one-way valve body is used to vent the gas. This allows the telescopic end of the first reciprocating cylinder 42 to drive the first clamp 4 and the second reciprocating cylinder 44 to drive the second clamp 41 towards the die clamping position to achieve die clamping.

[0044] Furthermore, taking the structure at the second clamp 41 as an example, in order to make the movement of the second clamp 41 smoother, a buffer sleeve 43 is also fitted on the jaw tilting shaft 2. The buffer sleeve 43 is fixed on the end of the jaw tilting shaft 2 away from the jaw clamping position, and a movable buffer is connected between the buffer sleeve 43 and the second clamp 41. When the second clamp 41 slides, it pushes the movable buffer towards the buffer sleeve 43. The movable buffer can provide a reaction force to the second clamp 41, thus enabling the second clamp 41 to move more smoothly.

[0045] In one embodiment of this application, the movable buffer is specifically selected as a telescopic spring 431. When the second clamp 41 opens, it moves toward the buffer sleeve 43, causing the telescopic spring 431 to be in an extended state. The elastic force of the telescopic spring 431 itself can buffer the second clamp 41. When the second clamp 41 moves toward the first clamp 4, the telescopic spring 431 slowly returns to its initial state, and the elastic force of the telescopic spring 431 itself can assist the second clamp 41 in resetting, making it more convenient to use. The first clamp 4 is provided with a buffer sleeve 43 and a telescopic spring 431 of the same structure.

[0046] Furthermore, a fixed baffle stroke nut 432 is added to the buffer sleeve 43. The stroke nut 432 is specifically located at the end of the buffer sleeve 43 away from the die clamping position to limit the movement of the first clamp 4 or the second clamp 41, facilitating die replacement by the operator. The operator can change the position of the stroke nut 432 on the buffer sleeve 43, thereby changing the opening stroke of the first clamp 4 and the second clamp 41 to accommodate dies of different sizes.

[0047] To facilitate operation, the flipping mechanism is equipped with two sets of identical die clamping mechanisms. The two die clamping mechanisms are respectively located at both ends of the length direction of the flipping shaft 2 to improve the working efficiency of the bottle making machine.
