Description

Two-way opening and closing control device for the upper and lower chucks of the bottle making machine

technical field

The utility model relates to a bidirectional opening and closing control device for upper and lower chucks of a bottle making machine. the

Background technique

The Chinese patent document disclosed a technical scheme of "Intermittent bottle making machine linkage double chuck" with the patent number "02247174.X" on August 6, 2003. The technical scheme is composed of two identical structures assembled on the same axis. It consists of upper and lower chuck assembly and a driving mechanism that controls the opening and closing of the upper and lower chucks. The driving mechanism mainly includes a linkage shaft and an upper and lower horizontal connecting rod. When the device is in use, by operating the operating handle integrated with the lower transverse connecting rod, the linkage control of the upper and lower chucks of the bottle making machine is realized by the linkage shaft and the upper and lower transverse connecting rods. But this kind of structure also has the following disadvantages: the first is that the driving resistance is large. Because the device adopts a single lever driving mode, the driving force to open the upper and lower chucks of the bottle making machine is increased by manual operation and bottle making machine driving control. The second is that the structure applicable to the control chuck is single. Since the device adopts a single lever type to control the linkage of the upper and lower chucks, it can only realize the linkage operation control of the upper and lower tapered chucks in the same direction, and cannot be used for lever-type or swing-type chucks. Perform linkage control. Bring great inconvenience to production. the

Contents of the invention

The purpose of this utility model is to provide a bidirectional opening and closing control device for the upper and lower clamps of the bottle making machine that overcomes the above-mentioned shortcomings.

The purpose of this utility model is achieved in this way: the upper and lower chuck bidirectional opening and closing control device of the bottle making machine includes two upper and lower chuck assemblies with the same structure assembled on the same axis and controls the opening and closing of the upper and lower chucks. The drive mechanism is composed of a base fixed on the aluminum plate of the bottle making machine, a drive gear assembled on the base, guide rod sleeves on both sides of the drive gear, and upper and lower guide rods. The drive gear is assembled on the base through the drive shaft, and the two guide rod sleeves are symmetrically mounted on the base on both sides of the drive gear; one end of the upper and lower guide rods is provided with a rack, and the upper and lower guide rods The rack ends are installed in the guide rod sleeves respectively, the racks of the upper and lower guide rods are engaged with the driving gear respectively, and the other ends of the upper and lower guide rods are respectively connected with the pulley frames of the upper and lower chucks of the bottle making machine.

The above-mentioned driving shafts are respectively connected with the operating rod or the output driving rod of the driving cam of the bottle making machine. the

The technical progress achieved by the utility model: the device adopts the two-way drive control mode of the gear type upper and lower guide rods. That is to say, the driving gear drives the upper and lower guide rods at the same time, and the upper and lower guide rods respectively push the pulley frame that controls the opening and closing of the upper and lower chucks to generate displacement, so as to realize the opening and control of the upper and lower chucks. This kind of two-way driving control mode greatly reduces the driving force for controlling the opening and closing of the chuck of the bottle making machine, that is, it is not only easy to operate manually. And it also greatly reduces the driving force of the driving cam of the bottle making machine. At the same time, this drive mode has a stable propulsion control and precise displacement control, which ensures the accurate positioning of the opening and closing of the upper and lower chucks, effectively ensures the bottle-making accuracy of the bottle-making machine, improves product quality, and reduces the failure rate of the bottle-making machine. Reduced maintenance and reduced maintenance costs. Secondly, the bidirectional drive control mode can realize the opening and closing control of chucks of various structures, and is an ideal bidirectional opening and closing control device for the upper and lower chucks of the bottle making machine. the

Detailed ways

As shown in Figures 1 and 2, the two-way opening and closing control device for the upper and lower chucks of the bottle making machine includes two upper and lower chuck assemblies 1 and 2 with the same structure and assembled on the same axis, and a device for controlling the opening and closing of the upper and lower chucks. Drive mechanism, said drive mechanism consists of a base 4 fixed on the aluminum plate 3 of the bottle making machine, a drive gear 5 assembled on the base 4, and guide rod sleeves 6, 7 symmetrically installed on both sides of the drive gear 5 and The upper and lower guide rods 8 and 9 are composed, the base 4 is fixed on the aluminum plate 3 of the bottle making machine, the driving gear 5 is connected with the base 4 through the driving shaft, the other end of the driving shaft is connected to the operating handle 12, and the guide rod sleeve 6 and 7 are symmetrically and fixedly assembled on both sides of the driving gear 5 respectively. One end of said upper and lower guide rods 8,9 is respectively provided with a rack, and it is provided with a rack end which is respectively worn in the guide rod sleeves 6,7, and the racks of the upper and lower guide rods 8,9 are respectively connected with the drive The gear 5 is meshed and connected, and the other ends of the upper and lower guide rods 8, 9 are respectively connected with the pulley frames 10, 11 of the upper and lower chucks of the bottle making machine. the

When the two-way opening and closing control device of the upper and lower chucks of the bottle making machine is working, the driving gear 5 is driven to rotate through the operating handle, and the driving gear 5 drives the upper and lower guide rods 8 and 9 respectively to produce up and down displacements in opposite directions. The upper and lower guide rods 8 and 9 That is to drive the action of the pulley frame of the chuck of the bottle making machine, and through the action of the pulley on the pulley frame on the shoulder surface of the chuck of the bottle making machine, the opening and control of the upper and lower chucks of the bottle making machine are realized. the
