Description

Technical Field

[0001] The invention relates to the technical field of bottle making machines, and in particular to an electrically driven cylinder bottle clamping mechanism. Background Art

[0002] As a key molding equipment in the glass industry, the bottle making machine plays a vital role in the production of glass factories. After the molten glass is sheared by the scissors of the feeder, it becomes a glass embryo, which is guided by the flow device into the molding equipment for molding. The bottle mouth and the inner cavity of the glass bottle are initially molded in the preliminary mold, and then the turning mechanism puts the initially molded glass bottle into the molding mold for final molding, and becomes a glass bottle that meets the requirements of size and weight.

[0003] In the early days of the industry, finished glass bottles were manually clamped onto mesh bags. Later, with the continuous upgrading and development of automation, the bottle making machine was equipped with an automatic bottle clamping device, which clamped the glass bottles onto the conveyor mesh belt by mechanical action. At present, the automatic bottle clamping mechanism on the bottle making machine is divided into two categories. One is the servo bottle clamping system composed of servo motors and mechanical clamp arms and other components. The planetary gear drives the clamp arm to swing back and forth to clamp the bottle onto the stop plate of the bottle conveyor, and then the electronic bottle pusher mechanism pushes the bottle onto the bottle conveyor mesh belt to complete the conveying; the other is the cylinder bottle clamping system composed of multiple cylinders arranged horizontally and vertically. The horizontal cylinder drives the clamp claw to move forward and backward, and the vertical cylinder drives the clamp claw to move up and down, thereby realizing the reciprocating motion of the clamp claw.

[0004] The servo bottle clamping system must use the bottle pushing mechanism to convey the bottles to the mesh belt, and the bottle pushing action is to push the bottle onto the bottle conveying mesh belt through the pushing claws. This action will cause small bottles such as concave bottom bottles and small cosmetic bottles to fall over, scratch and other defects. Therefore, some glass factories will choose the cylinder bottle clamping system, but the cylinder bottle clamping system will have unstable action after long-term use. Summary of the invention

[0034] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0035] An embodiment of the present application provides an electrically driven cylinder bottle clamping mechanism.

[0036] In one embodiment, referring to Figure 1 , Figure 1 This is a schematic diagram of the structure of an embodiment of the electric-driven cylinder bottle clamping mechanism of the present application. Figure 1 As shown, the electrically driven cylinder bottle clamping mechanism comprises: a mounting plate 1, a guide rail 2, at least one bottle clamping cylinder 3 and an electrically driven device 4.

[0037] The guide rail 2 is fixed on the mounting plate 1 , and at least one first sliding block 21 is provided on the guide rail 2 ; the bottle clamping cylinder 3 is fixed on the first sliding block 21 .

[0038] The electric drive device 4 is fixed on the mounting plate 1, and the electric drive device includes a motor 41 and a ball screw module 42. The ball screw module 42 is provided with a second slider 421, and the second slider 421 is connected to the bottle clamp cylinder 3. The motor 41 is used to drive the second slider 421 to move linearly to drive the bottle clamp cylinder 3 to slide along the guide rail 2.

[0039] Preferably, the motor 41 is a servo motor. It is worth mentioning that the drive system provides the core components for the electric-driven cylinder bottle clamping mechanism, which plays a vital role in the entire bottle clamping mechanism and even the entire bottle making machine system. Therefore, it is of great significance to ensure the stability of the operation of the structure. Its stability is related to whether the entire production line can operate normally. After years of development, the stability and work efficiency of the servo motor and ball screw can meet the requirements of the glass factory. The use of the motor can improve the overall quality of the equipment, which is of great significance.

[0040] It is understandable that the motor 41 is used to drive the ball screw module 42, and the rotation of the motor is converted into the linear motion of the ball screw, so as to drive the second slider 421 to slide, and then drive the bottle clamping cylinder 3 to slide along the guide rail 2. The structural mode of the motor with the ball screw has structural stability and position accuracy, can operate continuously for a long time, is not affected by unstable factors of the air source, and has smooth movement and low noise. Therefore, by introducing the ball screw module 42, the drive is changed from pneumatic to electric, which solves the problem of unstable operation of the cylinder in long-distance transportation, and greatly improves the speed of the equipment bottle clamping.

[0041] Furthermore, the electric drive device 4 is isolated from the mold of the bottle making machine based on the guide rail 2, and is arranged side by side with the guide rail 2 along the width direction of the guide rail 2. That is to say, the electric drive device 4 is farther away from the mold of the bottle making machine than the guide rail 2, which greatly facilitates the maintenance of the operator and minimizes the influence of the high temperature of the mold on the motor. At the same time, since the electric drive device 4 and the guide rail 2 are arranged side by side in the width direction, the installation space can be saved.

[0042] Preferably, see also Figure 2 As shown, a heat shield 11 covering the motor 41 is also extended from the end of the mounting plate 1, and a blow block 12 is fixed on the heat shield 11, and the blow block 12 is located between the heat shield 11 and the motor 41. In addition, the electric drive device also includes a shield 43 covering the motor 41 and the ball screw module 42.

[0043] Since the glass factory is in a high-temperature working environment all year round, the present application arranges a heat insulation plate 11 under the motor 41, and a protective cover 43 above the motor 41. A blowing block 12 is installed on the heat insulation plate 11, which can be connected to an air source to blow air to the motor 41 to dissipate the heat generated during the operation of the motor, ensuring that the motor operates at a low temperature for a long time, greatly reducing the failure rate of the motor in a high-temperature environment.

[0044] See also Figure 3As shown, in order to further improve the bottle clamping efficiency, the electrically driven cylinder bottle clamping mechanism includes two bottle clamping cylinders 3, two first sliders 21 are provided on the guide rail 2, each bottle clamping cylinder 3 is fixed on a first slider 21, the two bottle clamping cylinders 3 are connected by a pull rod 31, and one bottle clamping cylinder 3 is connected to the second slider 421 through an adapter plate 32. Specifically, the bottle clamping cylinder 3 includes a cylinder mounting plate 35, and the adapter plate 32 is respectively connected to the two cylinder mounting plates 35 to form a whole. The actions of the two bottle clamping cylinders 3 are controlled by the same air source to ensure the consistency of the cylinder action. The installation spacing of the two bottle clamping cylinders 3 is 250mm, and one action can clamp two bottles at the same time to a distance of 250mm. At the corresponding position, a stop plate and a bellows are installed on the bottle conveyor for the transition of the glass bottle position and the cooling of the bottle bottom. The bottle clamping cylinder 3 is provided with an air inlet at the top and bottom, and the compressed air is controlled by the solenoid valve to drive the cylinder piston to move up and down.

[0045] It can be understood that the pull rod 31 connects the two bottle clamp cylinders 3 together, and one of the bottle clamp cylinders 3 is connected to the second slider 421, so that when the second slider 421 slides, it can slide with the two bottle clamp cylinders 3, and a bottle clamp clamp 34 is provided at the bottom of each bottle clamp cylinder 3, and the bottle clamp clamp 34 has an air inlet, and the clamping action of the bottle clamp clamp 34 is controlled by air pressure. A spring is provided inside the bottle clamp clamp 34. After the air supply is stopped, the spring acts to control the release action of the bottle clamp 34.

[0046] In addition, the electrically driven cylinder bottle clamping mechanism also includes a bottle supporting cylinder 7, which is located in front of the bottle clamping cylinder. The bottle supporting cylinder 7 is a double-acting cylinder, which controls the up and down movements of the cylinder by air pressure. The bottle supporting movement precedes the bottle clamping movement. After the bottle supporting cylinder 7 moves, the bottle supporting head will be pushed above the mold to cover the bottle mouth, and then the molding mold will be opened, so as to ensure the stability of the glass bottle when the mold is opened and prevent the bottle from falling over.

[0047] See also Figure 4 As shown, in order to facilitate the adjustment of the electrically driven cylinder bottle clamping mechanism, the electrically driven cylinder bottle clamping mechanism also includes a supporting device 5 fixed to the bottom end of the mounting plate 1, and a lifting and lowering adjusting device 6 installed in the supporting device.

[0048] The supporting device 5 includes a base plate 51 , a support 52 and a guide sleeve 53 .

[0049] The bottom plate 51 is provided with a plurality of U-shaped notches for adjustably fixing the bottom plate 51 to the chassis of the bottle making machine through the U-shaped notches; it is understandable that the U-shaped notches have a little installation margin, so that the position of the entire electrically driven cylinder bottle clamping mechanism can be finely adjusted.

[0050] The support 52 is fixed on the base plate 51, and a hollow raised structure is provided inside the support 52, and an internal thread that cooperates with the lifting and lowering adjustment device 6 is provided inside the raised structure; in other words, there is a cavity inside the support 52, and a raised structure is cast in the cavity. The inside of the raised structure is opened up through processing, and the tapping on the upper side cooperates with the corresponding screw shaft to adjust the height. A hole is opened at the lower side, and the hole diameter is larger than the thread diameter to avoid air.

[0051] The guide sleeve 53 is fixed on the support 52, and the guide sleeve 53 is provided with a positioning groove to be fixed with the lifting adjustment device 6 through a keyway. It is worth noting that the entire support device 5 is a hollow structure inside, which optimizes the weight of the mechanism to the greatest extent while ensuring the stability of the support, facilitates the installation and transportation, and reduces the cost of the equipment.

[0052] The lifting and lowering adjustment device 6 includes a guide shaft 61 , an upper bracket 62 and a screw shaft 63 .

[0053] The guide shaft 61 is a hollow structure, and one end of the guide shaft 61 is provided with a flat key for cooperating with the positioning groove; it can be understood that the guide shaft 61 and the positioning groove can play a good fixing role and prevent shaking through the key groove cooperation.

[0054] The upper bracket 62 is fixed on the mounting plate 1 and connected to the other end of the guide shaft 61. The upper bracket 62 is also provided with a mutually meshing active bevel gear 621 and a driven bevel gear 622. A shaft with a flattened opening is also extended from the active bevel gear 621. Specifically, the upper bracket 62 is a welded structure, and two mutually perpendicular holes are provided inside for installing the active bevel gear 621 and the driven bevel gear 622. The active bevel gear 621 and the driven bevel gear 622 are meshed with each other inside the upper bracket 62. The active bevel gear 621 extends a shaft with a flattened opening on the shaft for easy manual height adjustment.

[0055] The screw shaft 63 is received in the guide shaft 61, and one end of the screw shaft 63 is threadedly matched with the protruding structure, and the other end is connected to the driven bevel gear 622. The screw shaft 63 is directly connected to the driven bevel gear 622, and is equipped with a pair of bearings 64 to ensure that the rotation of the driven bevel gear 622 can directly drive the screw shaft 63 to rotate, thereby realizing the overall lifting adjustment.

[0056] The lifting adjustment device 6 is used when the product is changed and installed for the first time. By adjusting the height of the upper bracket 62, it can adapt to the production of glass bottles of different heights. When adjusting, it is only necessary to use a wrench to twist the flat mouth on the active bevel gear 621 to achieve the lifting and lowering of the overall bottle clamp. The operation is convenient and the efficiency of the change of production is greatly improved.

[0057] Correspondingly, see Figure 3As shown, a support shaft 13 is also provided on the mounting plate 1, and a cylinder limit bracket 131 is provided on the support shaft 13. The top of a bottle clamp cylinder 3 is also provided with a cross bar 33 that cooperates with the cylinder limit bracket 131 to limit the vertical direction, so as to impose certain restrictions on the adjustment of the lifting and adjusting device 6.

[0058] In summary, the electric-driven cylinder bottle clamping mechanism in the present application includes an electric drive device 4, which includes a motor 41 and a ball screw module 42. The motor 41 is used to drive the ball screw module 42 to move, so as to drive the bottle clamping cylinder 3 to slide along the guide rail. Therefore, by introducing the ball screw module 42, the drive is changed from pneumatic to electric, which solves the problem of unstable operation of the cylinder during long-distance transportation, and greatly improves the speed of the equipment bottle clamping.
