Description

Technical Field

[0001] The utility model belongs to the technical field of glass product production, and particularly relates to a sucker cooling device for a glassware blowing machine. Background Art

[0002] Glassware refers to utensils made of glass and is one of the common glass products. During the preparation and processing of glassware, blow molding is one of the most common processing methods. Among them, the blowing machine is one of the main devices in the blow molding of glassware. At the same time, during the use of the blowing machine, in order to facilitate the transportation of glassware or its blank, a sucker is usually used. The sucker is used to adsorb and fix the glassware or its blank, thus facilitating its transportation. In order to avoid damage to the sucker caused by the heat on the glassware or its blank, a cooling device is additionally provided on the sucker to cool the sucker.

[0003] The existing sucker cooling device is generally an annular cooling groove around the outer wall of the sucker, and cold water flowing in the annular cooling groove is used to absorb heat from the sucker for cooling. However, there are the following disadvantages in the use process:

[0004] When the existing sucker cooling device is in use, since its size is fixed and there are various models of suckers, and the sizes of different models of suckers are different, it results in that the annular cooling groove of the same size can only be used on the suckers of the same model, and its application range is small.

[0005] When the existing sucker cooling device is in use, cold water circulates in the annular cooling groove, and the cold water is used to absorb heat from the sucker for cooling. However, since the cold water needs to flow around the sucker while absorbing heat, the temperature of the cold water will gradually increase during the flowing process, and further, the heat absorption and cooling of each part of the sucker by the annular cooling groove are uneven, and the cooling effect is poor.

[0006] Therefore, we provide a sucker cooling device for a glassware blowing machine to solve the above problems. Content of the Utility Model

[0007] The purpose of the utility model is to provide a sucker cooling device for a glassware blowing machine. The U-shaped frame drives the connecting plate to move relative to the arc-shaped block, so as to adjust the distance between the arc-shaped blocks, and further facilitate the installation of the cooling structure on suckers of different sizes, solving the problem that the existing one is not convenient to be used for blow machine suckers of different sizes. And two groups of cooling pipes are used to provide cooling water with different flow directions for the sucker body, so as to keep the temperature of each heat exchange plate the same, and further solve the problem that the existing one is not convenient to evenly cool each part of the blow machine sucker.

Embodiment 1

[0038] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, it is the first embodiment of the present utility model. This embodiment provides a sucker cooling device for a glassware blowing machine, which includes a sucker body 100.

[0039] Specifically, the arc-shaped blocks 201 are respectively located on the outer periphery of the sucker body 100. Installation cavities 201a are opened inside the arc-shaped blocks 201. Connecting plates 202 are arranged between adjacent arc-shaped blocks 201. Both sides of the connecting plate 202 are slidably connected inside the installation cavity 201a. Both outer walls of the arc-shaped blocks 201 are movably connected with U-shaped frames 203. Damping plates 204 are movably connected inside the U-shaped frames 203. The inner side surfaces of the damping plates 204 are in contact connection with the outer side surfaces of the arc-shaped blocks 201. The installation plate 300 is fixed on the outer wall of the arc-shaped block 201 close to the sucker body 100. The installation cavity 201a is used for installing the connecting plate 202. The connecting plate 202 is used for connecting the arc-shaped blocks 201 and adjusting the distance between the arc-shaped blocks 201. The U-shaped frame 203 is used for driving the connecting plate 202 to move. The damping plate 204 is used for fixing the U-shaped frame 203.

[0040] Furthermore, a first connecting pipe 101 is fixedly communicated with the top of the sucker body 100, and a rubber ring 102 is bonded to the bottom of the sucker body 100;

[0041] Chute one 201b is provided at both the top and bottom of the arc-shaped block 201. Chute one 201b communicates with the installation cavity 201a. On both sides inside chute one 201b, there are slidably connected slider ones 203a. One ends of slider ones 203a located outside the installation cavity 201a are respectively welded on the facing surfaces of the horizontal arms of the U-shaped frame 203, and one ends of slider ones 203a located inside the installation cavity 201a are respectively welded on the upper and lower surfaces of the connecting plate 202;

[0042] A sleeve rod 203b penetrates through the vertical arm of the U-shaped frame 203. A threaded rod 204a is threadedly sleeved inside the sleeve rod 203b. One end of the threaded rod 204a located inside the U-shaped frame 203 is rotatably connected to the outer side surface of the damping plate 204, and one end of the threaded rod 204a located outside the U-shaped frame 203 is fixedly connected with a knob 204b;

One end of the positioning post 201c located outside the positioning hole 301 is welded on the outer wall of the arc-shaped block 201 close to the mounting plate 300.

[0045] The operation process of this embodiment is as follows: Apply an external force to the U-shaped frame 203, so that the U-shaped frame 203 drives the connecting plate 202 to move inside the installation cavity 201a through the slider one 203a, and then adjust the distance between the arc-shaped blocks 201 through the movement of the connecting plate 202. When the distance between the arc-shaped blocks 201 reaches the preset value, rotate the knob 204b. The knob 204b drives the threaded rod 204a to rotate synchronously. And under the action of the threaded connection between the threaded rod 204a and the sleeve rod 203b, the threaded rod 204a drives the damping plate 204 to move. When the damping plate 204 abuts against the outer wall of the arc-shaped block 201, stop rotating the knob 204b. Rely on the friction force between the damping plate 204 and the arc-shaped block 201 to fix the U-shaped frame 203, and then fix between the arc-shaped block 201 and the connecting plate 20, realizing the adjustment of the distance between the arc-shaped blocks 201.
