Description

Technical Field

[0001] The invention belongs to the technical field of filling machines, and in particular relates to a water needle filling machine with the function of reducing residual oxygen content. Background Art

[0002] A Chinese patent with authorization announcement number CN214357038U discloses a water injection filling machine, including a bottle feeding mechanism, a front nitrogen filling mechanism, a filling mechanism, a rear nitrogen filling mechanism, a wire drawing and sealing mechanism and a nitrogen gas curtain row. The bottle feeding mechanism includes a bottle feeding conveyor belt, and the front nitrogen filling mechanism, the filling mechanism, the rear nitrogen filling mechanism and the wire drawing and sealing mechanism are sequentially arranged in the conveying direction of the bottle feeding conveyor belt; a nitrogen gas curtain row is arranged above the bottle feeding conveyor belt between the inlet of the bottle feeding mechanism and the front nitrogen filling mechanism, and a nitrogen gas curtain row is arranged above the bottle feeding conveyor belt between the rear nitrogen filling mechanism and the wire drawing and sealing mechanism; the interior of the nitrogen gas curtain row is a hollow air cavity, and the cross-section of the air cavity in the width direction is an inverted trapezoid. An air inlet pipe connected to the air cavity is arranged on the outer wall of the nitrogen gas curtain row, and the bottom of the nitrogen gas curtain row is parallel to The bottle conveying conveyor belt is provided with a strip-shaped air outlet in the conveying direction, the air outlet is connected to the air cavity, and baffles are provided on both sides of the air outlet. The bottle conveying conveyor belt rotates to drive the ampoule bottle to move forward from the entrance of the bottle conveying mechanism. The ampoule bottle is always in the nitrogen air curtain formed by the narrow and long strip air outlet of the nitrogen air curtain row in the process of reaching the front nitrogen filling mechanism and the wire drawing and sealing mechanism. The nitrogen air curtain enters the ampoule bottle to replace the air in the bottle. The baffles on both sides of the air outlet form a channel for the bottle mouth of the ampoule bottle to pass through. The continuously sprayed nitrogen air curtain and the excess nitrogen overflowing from the ampoule bottle form a nitrogen protection area in the channel. The bottle mouth of the ampoule bottle is always in the nitrogen protection area, which solves the technical problem that the ampoule bottle lacks nitrogen protection throughout the process from the bottle conveying process to the wire drawing and sealing process.

[0003] However, this technical solution still has at least the following defects: this solution can effectively protect the ampoule bottle from the bottle feeding process to the wire drawing and sealing process, but in the sealing process, when the filling machine is filling, the spray gun will disturb the surrounding airflow, causing air to enter the ampoule bottle.

[0050] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0051] Example 1

[0053] The top of the heat sealing box 100 is provided with an air filling mechanism, which includes a cannula 106, which is movably plugged into the top of the heat sealing box 100, and an air hole 107 is provided at the end of the cannula 106. The air filling mechanism injects inert gas through the cannula 106, and the air hole 107 is arranged at an angle to prevent the liquid medicine in the ampoule from being flushed out by a large airflow;

[0054] A moving mechanism is provided on one side of the heat sealing box 100 , a pushing device is installed on the moving mechanism, a sealing plate 203 is installed at the output end of the pushing device, the sealing plate 203 is adapted to the heat sealing box 100 , and a sealed space is formed by the heat sealing box 100 and the sealing plate 203 .

[0055] like Figure 3 , Figure 5 , Figure 6As shown, in a specific embodiment, the inflation mechanism also includes a connecting seat 105, an air inlet pipe 108 is installed on the top of the connecting seat 105, and the insertion tube 106 is connected to the connecting seat 105. A gas valve switch 109 is installed on one side of the connecting seat 105, and the gas valve switch 109 is used to control the connection between the air inlet pipe 108 and the insertion tube 106. A baffle 110 is installed on the top of the heat sealing box 100, and the position of the baffle 110 corresponds to the position of the gas valve switch 109. The plane where the baffle 110 is close to the side of the gas valve switch 109 is aligned with the gas valve switch 109 when the gas valve switch 109 is in the open state, so that when the gas valve switch 109 descends, one side of the baffle 110 abuts against the gas valve switch 109 and opens it. A movable plug 104 is installed on one side of the connecting seat 105, and the movable plug 104 is movably plugged in the top of the heat sealing box 100. Springs 302 are arranged on both sides of the connecting seat 105. In this configuration, the air valve switch 109 is a time-delay switch, and the vacuum pump 102 evacuates air from the heat sealing box 100. As the pressure in the heat sealing box 100 gradually decreases, the movable plug 104 gradually moves downward due to the negative pressure, and drives the connecting seat 105 to move downward. The connecting seat 105 drives the cannula 106 to move downward and extend into the ampoule. When the connecting seat 105 descends, it drives the air valve switch 109 to move downward. When the air valve switch 109 descends to the baffle 110, the baffle 110 pushes the air valve switch 109 to open. At this time, the inert gas enters the cannula 106 through the air inlet pipe 108, enters the ampoule through the cannula 106, and diffuses into the heat sealing box 100. At the same time, the pressure in the heat sealing box 100 gradually increases, causing the cannula 106 to rise under the action of the spring 302. During the rising process, the air valve switch 109 is closed with a delay, so that the cannula 106 continues to transport the inert gas during the rising process.

In this configuration, when the cannula 106 rises, the insertion rod 301 rises with it and drives the gear 304 to rotate through the tooth groove 303. The gear 304 drives the damper 307 to rotate through the ratchet 305 and the pawl 306. The damper 307 limits the speed of the rotation of the gear 304, thereby limiting the speed of the rise of the cannula 106.

In this arrangement, the preheating gun 400 is used to preheat the ampoule bottle, so that the ampoule bottle can be quickly heat-sealed when the heat sealing gun 101 is used later. The inclined conveying device 401 is convenient for transporting the ampoule bottle to prevent it from tipping over, and is conducive to the clamping mechanism to clamp it.

[0061] Example 3

[0062] like Figures 9 to 15As shown, a water needle filling machine with a function of reducing residual oxygen content also includes a processor, and the processor is configured with an intelligent control system for controlling the operation of the water needle filling machine, and the intelligent control system includes a moving unit and an operating unit;

[0063] The moving unit is used to control the logical sequence of the electric slide 201 when it moves;

[0064] The operation unit controls the movement of the electric slide 201 based on the moving unit, and realizes the clamping, heat sealing and separation operations of the ampoule bottle.

[0065] The mobile unit includes a position setting strategy, which includes configuring the electric slide 201 with a default point, a preheating point, a release point and a separation point, wherein the default point represents the position where the electric slide 201 is aligned with the heat sealing box 100, the preheating point represents the position where the electric slide 201 is aligned with the preheating gun 400, the release point represents the position where the electric slide 201 is located when the first ampoule bottle on the sealing plate 203 contacts the guide plate 500, and the separation point represents the position where the electric slide 201 is located when the end ampoule bottle on the sealing plate 203 is detached;

[0066] The position making strategy also includes a cyclic movement program, which represents a single cyclic movement of the electric slide 201 along the default point, preheating point, default point, release point, separation point and default point. Each cyclic movement takes the next point as the end point, confirms the next movement direction based on the last point, ends the current movement when it reaches the end point, and generates a node instruction.

[0067] The operation unit includes a reset identification strategy, which includes obtaining the current movement state of the electric push rod 202, generating a reset instruction when the electric push rod 202 contracts from the extended state to the compressed state, and generating an extension instruction when the electric push rod 202 extends from the compressed state to the extended state;

[0068] The operation unit also includes a clamping strategy, which controls the electric push rod 202 based on the current position of the electric slide 201 and the node instruction generated by the position formulation strategy. When the electric slide 201 moves to the preheating position and obtains the node instruction, the electric push rod 202 is controlled to perform a telescopic movement, indicating that the electric push rod 202 drives the clamping mechanism to clamp the ampoule bottle, otherwise the electric push rod 202 is in a standby state;

[0069] The operation unit also includes a vacuum strategy, which controls the electric push rod 202 based on the last position of the electric slide 201 and the node instruction generated by the position formulation strategy. When the last position of the electric slide 201 is a preheating position and the node instruction is obtained, the electric push rod 202 is controlled to extend, indicating that the sealing plate 203 is close to the heat sealing box 100;

[0070] The vacuum strategy also includes obtaining the instruction generated by the reset identification strategy and the current position of the electric slide 201. When the extension instruction is obtained and the electric slide 201 is at the default point, a vacuum instruction is generated, and the vacuum pump 102 is controlled to work based on the vacuum instruction;

[0071] The operation unit also includes a heat sealing strategy, which includes installing a position sensor in the connection seat 105, controlling the heat sealing gun 101 based on the position change of the position sensor and the instructions generated by the reset recognition strategy, when the extension instruction is obtained and the position sensor moves from bottom to top to stop, a heat sealing instruction is generated, and the heat sealing gun 101 is controlled to perform a heat sealing operation based on the heat sealing instruction, and a removal instruction is generated when the heat sealing operation is completed, indicating that the ampoule bottle has been sealed, and the electric push rod 202 is controlled to reset based on the removal instruction;

[0072] The operation unit also includes a disengagement strategy, which includes obtaining the current position of the electric slide 201 and the instructions generated by the reset identification strategy to control the movement of the electric slide 201. When the reset instruction is obtained and the electric slide 201 is in the default position, the electric slide 201 continues to execute the cyclic movement program and executes the disengagement program when it moves to the disengagement point. The disengagement program characterizes that when the electric slide 201 moves from the disengagement point to the separation point, the movement speed is limited, and based on the limited movement speed, the two adjacent ampoules will not squeeze each other when they are disengaged.

[0073] The implementation principle of the water needle filling and sealing machine with the function of reducing residual oxygen content in this embodiment is as follows: when working, the ampoule bottle is first preheated by the preheating gun 400, and the electric slide rail 200 and the electric slide table 201 drive the electric push rod 202 and the sealing plate 203 to move. When moving to the position corresponding to the preheating gun 400, the electric push rod 202 pushes the sealing plate 203 to move, and the sealing plate 203 clamps the ampoule bottle through the clamping plate 204 and the reset spring 205, clamping the ampoule bottle. After the ampoule is placed in the heat sealing box 100, the electric push rod 202 drives the sealing plate 203 to reset, and the electric slide rail 200 and the electric slide table 201 drive the sealing plate 203 and the ampoule to move to the heat sealing box 100. The sealing plate 203 is fitted with the heat sealing box 100 by extending the electric push rod 202. At this time, the vacuum pump 102 is started, and the vacuum pump 102 evacuates the heat sealing box 100. As the pressure in the heat sealing box 100 gradually decreases, the movable plug 104 is gradually moved downward by the negative pressure, and drives the connecting The seat 105 moves downward, the connecting seat 105 drives the cannula 106 to move downward and extend into the ampoule bottle. The connecting seat 105 moves downward while driving the gas valve switch 109 to move downward. When the gas valve switch 109 drops to the baffle 110, the baffle 110 pushes the gas valve switch 109 to open. At this time, the inert gas enters the cannula 106 through the air inlet pipe 108, enters the ampoule bottle through the cannula 106, and diffuses into the heat sealing box 100. At the same time, the pressure in the heat sealing box 100 is The force gradually increases, so that the cannula 106 rises under the action of the spring 302. When the cannula 106 is completely reset, the heat sealing gun 101 heats and seals the ampoule. After the sealing is completed, the electric push rod 202 drives the sealing plate 203 to reset, and the electric slide rail 200 and the electric slide 201 drive the sealing plate 203 to move to the guide plate 500. The guide plate 500 separates the ampoule from the clamping plate 204 and enters the guide groove 501, which is convenient for subsequent collection.

[0074] When the cannula 106 rises, the insertion rod 301 rises with it and drives the gear 304 to rotate through the tooth groove 303. The gear 304 drives the damper 307 to rotate through the ratchet 305 and the pawl 306. The damper 307 limits the rotation of the gear 304, thereby limiting the rise of the cannula 106.

[0075] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
