[0001] The application belongs to the field of glass container support positioning, in particular to a bevel cut glass container positioning device. BACKGROUND

[0002] When the glass container is processed, such as cutting, it needs to be supported by a base. The traditional method is to use a suction cup or a suction cup combined with a vacuum pump to increase the adsorption force and improve the fixing capacity. However, different shapes of glass containers need to be repeatedly adjusted and fixed in position and the base, so that the glass container reaches an angle suitable for processing. Increasing the number of suction cups can improve stability, but when the area covered by the suction cups is greater than the projection area of the glass container, some suction cups cannot be adsorbed on the glass container, and the vacuum pump continuously sucks these suction cups, affecting the efficiency of the vacuum pump, resulting in poor vacuum effect of the suction cups that have been adsorbed and low stability.

[0019] In the description of the present application, unless otherwise explicitly specified and limited, the terms “mounting”, “connection”, “connecting” should be understood in a broad sense, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium; it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0020] Referring to the accompanying drawings, the present embodiment provides a bevel cut glass container positioning device, comprising a base 1, the base 1 is provided with mounting holes, the mounting holes are fixed with sliding sleeve assemblies 2, support assemblies 3 are slidably connected with the sliding sleeve assemblies 2, the upper parts of the support assemblies 3 are in contact with the glass containers, locking assemblies 4 are fixed on the sliding sleeve assemblies 2, and the locking assemblies 4 can fix the positions of the support assemblies 3 relative to the sliding sleeve assemblies 2. The mounting holes on the base 1 are arranged in an array, and different numbers of mounting holes can be arranged according to specific use conditions, such as the size of the glass container. The sliding sleeve assemblies 2, the support assemblies 3 and the locking assemblies 4 are also arranged in an array, and the relative lengths of each support assembly 3 on the upper part of the sliding sleeve assembly 2 will change, such as the size of the downward compression, so as to adapt to glass containers of different shapes. In addition, the support assemblies 3 are connected with a negative pressure device, such as a vacuum pump, and a negative pressure is formed between the support assemblies 3 and the glass containers, so that the glass containers are more tightly positioned on the support assemblies 3. Then, gas is introduced into the locking assemblies 4, the locking assemblies 4 fix the support assemblies 3, the glass containers are supported and fixed.

[0021] In the present embodiment, the lower part of the sliding sleeve assembly 2 is provided with a bottom plate 6, and the support assembly 3 is provided between the bottom plate 6 and the spring 5. The spring 5 can be compressed according to the downward pressure of the glass container on the support assembly 3, and a supporting force is provided to the support assembly 3. When the glass container is removed, the support assembly returns to the original position under the action of the spring 5.

[0022] In the present embodiment, the bottom plate 6 is provided with a threaded column 7, one end of the spring 5 is sleeved on the threaded column 7, an adjusting nut 8 is threadedly connected with the threaded column 7, and one end of the spring 5 abuts against the adjusting nut 8. On the one hand, the pre-tightening force of the spring 5 can be changed by rotating the adjusting nut 8, so as to adjust the close degree of the support assembly 3 to the glass, and the two can maintain good sealing on the contact surface, so that the adsorption is not stable due to air leakage when the vacuum pump is pumping. On the other hand, before the locking assembly 4 tightly holds the support assembly 3 after the glass container is placed, the angle of the glass container can be finely adjusted by rotating the adjusting nut 8. When the adjusting nut 8 is rotated, the pre-tightening force of the spring 5 is changed, so as to adjust the upward or downward movement of the support assembly 3, thereby moving the glass container. The angles of the glass containers can be finely adjusted by adjusting different adjusting nuts 8.

[0023] In the present embodiment, the support assembly 3 comprises a support pipe 3-1, an air inlet 3-2 and a lower spring seat 3-3. The upper part of the support pipe 3-1 is in contact with the glass container, the lower spring seat 3-3 is connected with the spring 5, and the air inlet 3-2 is used for discharging internal gas. The air inlet 3-2 is connected with the vacuum pump, and the gas in the support pipe 3-1 is pumped out.

[0024] In the embodiment, the support tube 3-1 is provided with a sealing gasket 3-5 at the glass container contact end, and the sealing gasket 3-5 is fixed on the support tube 3-1 by a fixing ring 3-6. The sealing gasket 3-5 can be made of rubber or other materials to increase the sealing performance of the contact surface with the glass container. However, the sealing gasket 3-5 should not be too soft or too thick to prevent the deformation of the material from causing the glass container to be displaced due to new forces during processing.

[0025] In the embodiment, the radius of the middle hole of the fixing ring 3-6 is the same as the radius of the middle space 3-9 of the support tube 3-1, and the negative pressure plug 3-7 slides in the middle space 3-9 and the fixing ring 3-6. The lower part of the negative pressure plug 3-7 is provided with a reset spring 3-8. The fixing ring 3-6 and the middle space 3-9 form a channel for the movement of the negative pressure plug 3-7. After the gas in the lower part of the negative pressure plug 3-7 is sucked away, the negative pressure plug 3-7 moves downward under the action of the pressure difference, compresses the reset spring 3-8, and the volume of the space surrounded by the glass container, the fixing ring 3-6, the support tube 3-1, and the upper part of the negative pressure plug 3-7 increases, and the pressure decreases. Under the action of atmospheric pressure, the glass container remains fixedly connected to the sealing gasket 3-5. The presence of the negative pressure plug 3-7 can keep each support assembly 3 in a sealed state. If the area covered by the support assembly 3 is larger than the projected area of the glass container, some support assemblies 3 will not be in contact with the glass container, or some support assemblies 3 will be in contact with the glass container due to the angle and other reasons, which will affect the contact effect and may cause air leakage. In any case, if there is no negative pressure plug 3-7, the vacuum pump will continuously suck the gas in the above-mentioned support assemblies 3, and the external gas will also enter the support assemblies 3, thereby affecting the useful work of the vacuum pump. By setting the negative pressure plug 3-7, the internal space is isolated from the outside. Even if the above-mentioned situation occurs, when the negative pressure plug 3-7 compresses the spring to the maximum position, this support assembly 3 will not continue to suck external gas, thereby improving the useful work of the vacuum pump.

[0026] In the embodiment, the locking assembly 4 includes a housing 4-1, a contact piece 4-2, and a rear cover 4-4. The housing 4-1 is fixed on the sliding sleeve assembly 2, the contact piece 4-2 is slidably connected in the housing 4-1, and the housing 4-1 is divided into two spaces. The housing 4-1, the contact piece 4-2, and the rear cover 4-4 form a sealed space, and the rear cover 4-4 is provided with an inlet 4-5 in communication with the sealed space. The inlet 4-5 is connected to a gas supply device, such as a gas pump. The gas pump pumps gas into the sealed space through the inlet 4-5, the pressure in the sealed space increases, and the contact piece 4-2 is pushed away from the rear cover 4-4. The contact piece 4-2 will be in contact with the support tube 3-1 and will hold the support tube 3-1 tightly, so that the relative position of the support tube 3-1 and the sliding hole 2-2 in the middle of the upper surface 2-1 of the sliding sleeve assembly 2 remains unchanged, i.e., the locking state.

[0027] In the present embodiment, a release spring 4-3 for disengaging from the support tube 3-1 is provided between the housing 4-1 and the contact piece 4-2. The release spring 4-3 will disengage the contact piece 4-2 from the support tube 3-1 after the air pump has stopped supplying air.
