Description

Technical Field

[0001] This utility model relates to the technical field of beer bottle pressure detection, and in particular to a device for measuring the internal pressure of a beer glass bottle. Background Technology

[0002] Internal pressure testing of wine bottles is a crucial part of the production and quality control of alcoholic beverages (especially carbonated beer, sparkling wine, champagne, etc.); the pressure resistance of beer bottles must be tested before bottling.

[0003] For example, Chinese utility model patent CN217425013U discloses a pressure detection mechanism for ceramic wine bottles, including a housing, a cylinder mounted on the top of the housing, a conical plug at the end of the piston rod inside the cylinder cavity, a first air passage on the cylinder cavity, the first air passage including two speed regulating valves, a three-position four-way solenoid valve, and a first pressure gauge, with speed regulating valves mounted at both ends of the cylinder cavity. It is easy to operate and maintain, durable, highly accurate, and has a more reliable and functional leakage protection control circuit.

[0004] However, the above-mentioned device still has the following drawbacks: when performing internal pressure testing of beer bottles, it can only detect the positive pressure inside the beer bottle. However, beer bottles need to withstand a certain negative pressure during vacuum sterilization. If positive and negative pressure testing of beer bottles is to be completed, two sets of equipment are often required, and the beer bottle also needs to be moved between the two sets of equipment, which affects the pressure testing efficiency of the beer bottle and has certain limitations in use. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a beer bottle internal pressure measuring device that can perform positive and negative pressure detection on a beer bottle in a single operation without the need to move the beer bottle, thereby improving the detection efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a beer bottle internal pressure measuring device, comprising a frame, sealing clamps mounted on both sides of the frame, a first pipeline, a second pipeline, and a positive and negative pressure pressing mechanism mounted on the frame. The sealing clamps are used for clamping and sealing the bottle mouth. The positive and negative pressure pressing mechanism includes a housing, a crankshaft rotatably mounted within the housing, a transmission rod, and a piston. A motor is mounted on the housing to provide power for the crankshaft rotation. A pressure chamber that fits with the piston is provided inside the housing. The piston is slidably mounted within the pressure chamber. One end of the moving rod is hinged to the bottom of the piston, and the other end of the transmission rod is hinged to the eccentric part of the crankshaft. One end of the first pipeline and the second pipeline are both connected to the inside of the pressurization chamber, and the other ends of the first pipeline and the second pipeline are respectively connected to the inside of the corresponding sealing clamp. The sealing clamp is provided with a through hole connecting the inside of the sealing clamp and the inside of the beer bottle. A first switching valve is installed on the first pipeline, and a second switching valve is installed on the second pipeline. Furthermore, both the first switching valve and the second switching valve are preferably electrically controlled valves, and the electrically controlled valves are controlled to start and stop by an external PLC system.

[0007] Preferably, the sealing clamping component includes a hollow core rod, a conical plug mounted on the hollow core rod and integrally connected to the hollow core rod, and a clamping cover with a slit arranged along the axial direction. The clamping cover has fixing seats located on both sides of the slit, one fixing seat having a bolt rotatably mounted on it, and the other fixing seat having a screw hole that engages with the bolt. The bolt is screwed into the screw hole, and the through hole communicates with the interior of the hollow core rod. The inner wall of the clamping cover fits with the outer wall of the bottle mouth of the beer bottle. Further, the clamping cover is preferably a metal cap or a plastic cap with a certain degree of rigidity and plasticity.

[0008] Preferably, a water tank is installed on the top of the frame, and a lifting frame is slidably installed in the water tank. Two sealing clamps are respectively installed on both sides of the lifting frame. A lifting drive component is installed on the frame to provide power for the lifting frame to move up and down. Further, the lifting drive component is preferably an electric cylinder, which is fixedly installed on the frame and its output end is fixedly connected to the lifting frame. The lifting drive component can also be a mechanical slide or other equivalent component that can drive the lifting frame to move up and down. The connection between the first and second pipelines and the sealing clamps is made of a flexible plastic tube, which has a margin to allow the lifting frame to move up and down.

[0009] Preferably, an open header is placed on the lifting frame, and both sealing clamps are located on the upper part of the open header; furthermore, the bottom of the open header adopts a porous permeation plate that allows water to pass through.

[0010] Preferably, crossbars are fixedly installed on both sides of the lifting frame, and adjusting seats are rotatably installed on the crossbars. Tightening screws are screwed onto the adjusting seats, and the adjusting seats are fixedly connected to the crossbars through the tightening screws. The sealing clamps are fixedly installed on the corresponding adjusting seats.

[0011] Preferably, a pressure sensor connected to the interior of the hollow core rod is installed on the hollow core rod, and the pressure sensor is used to detect the internal pressure of the hollow core rod; furthermore, since the interior of the hollow core rod is connected to the interior of the beer bottle to be tested through a through hole, the internal pressure of the hollow core rod detected by the pressure sensor is the internal pressure of the beer bottle to be tested; the pressure sensor is electrically connected to an external display and a PLC system, and the real-time pressure value inside the beer bottle can be read through the external display.

[0012] Preferably, the inner wall of the clamping cap is provided with a concave annular groove that fits with the outer wall of the beer bottle nozzle.

[0014] Preferably, it also includes a connecting pipe, the two ends of which are respectively connected to the interior of two sealing clamps, and a third switching valve is installed on the connecting pipe.

[0015] Compared with the prior art, this utility model provides a device for measuring the internal pressure of beer bottles, which has the following advantages: This device clamps the nozzles of two beer bottles to two sealing clamps. A motor drives a crankshaft to rotate, and after transmission via a transmission rod, a piston moves up and down in the pressurization chamber. When the piston moves down in the pressurization chamber, the first switch valve opens and the second switch valve closes. Due to the negative pressure generated in the pressurization chamber, gas from the corresponding beer bottle enters the pressurization chamber through the first pipeline. When the piston moves up in the pressurization chamber, the first switch valve closes and the second switch valve opens, and the gas in the pressurization chamber is forced into the corresponding beer bottle through the second pipeline. This process is repeated to pressurize the inside of one beer bottle and draw negative pressure from the inside of the other beer bottle. Subsequently, the first switch valve closes when the piston moves down and the second switch valve opens. The direction of gas extraction is reversed according to the above principle, and the corresponding positive and negative pressure is detected inside the beer bottle. Positive and negative pressure detection of the beer bottle can be achieved in a single operation without moving the beer bottle, thus improving the detection efficiency. Attached Figure Description

[0017] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0018] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0019] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0020] Example 1 Please refer to Figure 1-7A device for measuring the internal pressure of a beer glass bottle includes a frame 1, sealing clamps mounted on both sides of the frame 1, a first pipeline 2, a second pipeline 3, and a positive and negative pressure pressurization mechanism mounted on the frame 1. The sealing clamps are used for clamping and sealing the bottle mouth. The positive and negative pressure pressurization mechanism includes a housing 4, a crankshaft 5 rotatably mounted inside the housing 4, a transmission rod 6, and a piston 7. A motor 8 is mounted on the housing 4 to provide power for the rotation of the crankshaft 5. A pressurization chamber 9 is provided inside the housing 4 that fits with the piston 7. The piston 7 is slidably mounted in the pressurization chamber 9. One end of the transmission rod 6 is connected to the piston 7. The bottom is hinged, and the other end of the transmission rod 6 is hinged to the eccentric part of the crankshaft 5. One end of the first pipe 2 and the second pipe 3 are both connected to the inside of the pressurization chamber 9. The other ends of the first pipe 2 and the second pipe 3 are respectively connected to the inside of the corresponding sealing clamp. The sealing clamp is provided with a through hole 10 connecting the inside of the sealing clamp and the inside of the beer bottle. A first switching valve 11 is installed on the first pipe 2, and a second switching valve 12 is installed on the second pipe 3. Furthermore, the first switching valve 11 and the second switching valve 12 are preferably electrically controlled valves, and the electrically controlled valves are controlled to start and stop by an external PLC system.

[0021] Specifically, it also includes a connecting pipe 31, the two ends of which are connected to the interior of two sealing clamps respectively, and a third switching valve 32 is installed on the connecting pipe 31.

[0022] For details, please refer to Figure 5 or Figure 7 A pressure sensor 26, which communicates with the interior of the hollow core rod 13, is installed on the hollow core rod 13. The pressure sensor 26 is used to detect the internal pressure of the hollow core rod 13. Furthermore, since the interior of the hollow core rod 13 is connected to the interior of the beer bottle to be tested through the through hole 10, the internal pressure of the hollow core rod 13 detected by the pressure sensor 26 is the internal pressure of the beer bottle to be tested. The pressure sensor 26 is electrically connected to an external display and a PLC system, and the real-time pressure value inside the beer bottle can be read through the external display.

[0023] For details, please refer to Figure 1 It also includes a cabinet 28, which has an installation cavity inside. The frame 1 is installed in the installation cavity. An opening and closing door 29 is hinged to the installation cavity of the cabinet 28. A transparent window 30 is provided on the opening and closing door 29. Furthermore, the transparent window 30 is made of transparent acrylic material or transparent tempered glass material.

[0024] The beer bottle internal pressure measuring device provided in this embodiment can detect the real-time pressure inside the beer bottle under test through the pressure sensor 26. The breaking limit pressure value of the beer bottle under positive or negative pressure can be read through an external display. If the limit pressure value exceeds the standard value, it indicates that the compressive strength of the beer bottle is qualified. When the positive pressure test of one beer bottle is completed and the negative pressure test of another beer bottle is required, the third switch valve 32 can be opened in advance. Under the action of the connecting pipe 31, the air pressure in the two beer bottles is balanced. Then the third switch valve 32 is closed, and the negative pressure test of one beer bottle is performed, while the positive pressure test of the other beer bottle is performed. There is no need to perform pre-balancing treatment of the pressure inside the two beer bottles through the positive and negative pressure pressurization mechanism, which is more energy-saving, shortens the pressure test time of the beer bottle, and further improves the test efficiency of the beer bottle. The cabinet 28 can prevent the glass shards generated during the pressurization and breakage of the beer bottle from flying around, avoiding injury to the surrounding operators and improving operational safety. The operator can observe the real-time status inside the cabinet 28 through the transparent window 30.

Figure 5 and Figure 7 The sealing clamping component includes a hollow core rod 13, a conical plug 14 mounted on the hollow core rod 13 and integrally connected to the hollow core rod 13 with a clamping cover 15, the clamping cover 15 having a slit 16 arranged along the axial direction, and the clamping cover 15 having fixing seats 17 located on both sides of the slit 16, one fixing seat 17 having a bolt 18 rotatably mounted on it, and the other fixing seat 17 having a screw hole that fits with the bolt 18, the bolt 18 being screwed into the screw hole, the through hole 10 communicating with the interior of the hollow core rod 13; the inner wall of the clamping cover 15 fits with the outer wall of the bottle mouth of the beer bottle; furthermore, the clamping cover 15 is preferably a metal cap or a plastic cap with a certain rigidity and plasticity.

[0026] For details, please refer to Figure 7 The inner wall of the clamping cap 15 is provided with a concave annular groove 27 that fits with the outer wall of the beer bottle nozzle.

[0027] The beer bottle internal pressure measuring device provided in this embodiment pushes the beer bottle so that the bottle mouth enters the clamping cap 15, the conical plug 14 is inserted into the bottle mouth, the fastening bolt 18 is tightened, the outer ring of the bottle mouth is inserted into the concave annular groove 27, the clamping cap 15 clamps the bottle mouth, and the conical plug 14 seals the bottle mouth, so as to achieve clamping and sealing of the beer bottle mouth.

[0028] Example 3 The internal pressure measuring device for beer glass bottles provided in Example 2 has been further optimized. For details, please refer to... Figures 2-4A water tank 19 is installed on the top of the frame 1, and a lifting frame 20 is slidably installed inside the water tank 19. Two sealing clamps are respectively installed on both sides of the lifting frame 20. A lifting drive component 21 is installed on the frame 1 to provide power for the lifting frame 20 to move up and down. Furthermore, the lifting drive component 21 is preferably an electric cylinder, which is fixedly installed on the frame 1 and its output end is fixedly connected to the lifting frame 20. The lifting drive component 21 can also be a mechanical slide or other equivalent component that can drive the lifting frame 20 to move up and down. The connection between the first pipe 2 and the second pipe 3 and the sealing clamp is made of a flexible plastic pipe, which has a margin to allow the lifting frame 20 to move up and down.

[0029] For details, please refer to Figures 2-4 An open header 22 is placed on the lifting frame 20, and both sealing clamps are located on the upper part of the open header 22; furthermore, the bottom of the open header 22 adopts a porous permeation plate that allows water to pass through, and the porous permeation plate does not allow glass fragments to pass through.

[0030] For details, please refer to Figures 2-5 as well as Figure 7 Both sides of the lifting frame 20 are fixedly installed with crossbars 23. Adjusting seats 24 are rotatably installed on the crossbars 23. Tightening screws 25 are screwed onto the adjusting seats 24. The adjusting seats 24 are fixedly connected to the crossbars 23 through the tightening screws 25. The sealing clamps are fixedly installed on the corresponding adjusting seats 24.

[0031] The beer bottle internal pressure testing device provided in this embodiment fills the water tank 19 with water. The lifting drive 21 moves the lifting frame 20 down until the sealing clamp and the beer bottle are completely immersed in the water tank 19. During the pressure test of the beer bottle, it is observed whether air bubbles are generated at the connection between the sealing clamp and the beer bottle, or whether water enters the beer bottle. If no air bubbles are generated and no external water enters the beer bottle, it indicates that the sealing clamp and the bottle neck are well sealed. The sealing performance between the beer bottle and the sealing clamp is then assessed. The system performs a test to ensure the accuracy of subsequent pressure testing; the open header 22 is used to collect the broken glass shards. When a beer bottle breaks in water, the glass shards are further reduced from scattering everywhere. The open header 22 also improves the ease of cleaning up the glass shards; by rotating the adjusting seat 24, the connection between the beer bottle and the clamping seal is completely immersed in water. When the open header 22 needs to be moved out of the lifting frame 20, rotating the adjusting seat 24 moves the sealing clamp away from the upper part of the open header 22, avoiding interference with the movement of the open header 22.

[0032] The operation of the beer bottle internal pressure measuring device provided by this utility model is as follows: The bottle mouths of two bottles are clamped to two sealing clamps. The motor 8 drives the crankshaft 5 to rotate. After transmission via the transmission rod 6, the piston 7 moves up and down in the pressure chamber 9. When the piston 7 moves down in the pressure chamber 9, the first switch valve 11 opens and the second switch valve 12 closes. Due to the negative pressure generated in the pressure chamber 9, the gas inside the beer bottle enters the pressure chamber 9 through the first pipe 2. When the piston 7 moves up in the pressure chamber 9, the first switch valve 11 closes and the second switch valve 12 closes. When switch valve 12 is opened, the gas in pressurization chamber 9 is forced into the corresponding beer bottle through the second pipeline 3. This process is repeated to pressurize the inside of one beer bottle and evacuate the inside of the other beer bottle. The positive or negative pressure value inside the corresponding beer bottle is read by pressure sensor 26. After the test is qualified, the third switch valve 32 is opened to make the gas pressure inside the two beer bottles the same. The first switch valve 11 is closed when piston 7 moves down, and the second switch valve 12 is opened. The direction of air evacuation is reversed according to the above principle, and the corresponding positive and negative pressure tests are then performed inside the beer bottles.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.
