Description

Technical Field

[0001] This invention relates to the technical field of fluid dispensing, and in particular to an intelligent integrated dispensing machine. Background Technology

[0002] Currently, silicone dispensing operations on the market mainly target two types of products: bottled silicone and drummed silicone. Existing dispensing equipment generally adopts the method of filling the container from the bottom, and then sealing the bottom after filling. During this traditional filling process, it is difficult to completely expel the air inside the container, which easily causes air to be trapped inside the silicone and generate residual bubbles. This not only affects the storage stability and performance of silicone products, but also easily leads to problems such as insufficient filling density and low product yield, which cannot meet the dispensing production requirements of high-quality silicone.

[0003] Patent CN220924755U discloses an organosilicone dispensing device. This device fills small-capacity bottled silicone through multiple dispensing tubes inside the dispensing tray. It has high production efficiency, but it cannot control the capacity well. The filling capacity of this structure is difficult to control stably, the metering accuracy is poor, and it is not compatible with the dispensing of large-capacity barrelled silicone.

[0004] Patent CN222886675U discloses a silicone dispensing production line, which uses a gear pump feeding mechanism to transport silicone from a large-capacity barrel to a small-capacity barrel in the dispensing station, achieving automatic dispensing and a high degree of automation. However, this structure can only be adapted to the filling operation of large-capacity barrel silicone, and the structure and station design are highly targeted, making it unsuitable for the dispensing production needs of small-capacity bottle silicone. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the prior art by proposing an intelligent combination and packaging machine that can solve the above problems.

[0006] To achieve the above objectives, the present invention proposes an intelligent combination and dispensing integrated machine, including a frame, a metering buffer cylinder on the frame, the metering buffer cylinder being connected to a feeding unit via a conveying pipeline, the metering buffer cylinder being connected to a discharge pipe, the discharge end of the discharge pipe being connected to a dispensing head, an inlet valve on the conveying pipeline, and a discharge valve on the discharge pipe.

[0007] Preferably, the dispensing head includes a bottle dispensing head and a barrel dispensing head. The discharge end of the bottle dispensing head is arranged facing upwards, and the discharge end of the barrel dispensing head is arranged facing downwards. The discharge end of the discharge pipe is provided with a quick switching mechanism, which can realize the switching of the discharge pipe, so that the discharge pipe is connected to the bottle dispensing head or the barrel dispensing head.

[0008] Preferably, the quick switching mechanism includes a union elbow channel with quick-connect clamps at both ends. One end of the union elbow channel is connected to the discharge pipe, and the other end is connected to the bottle dispensing head or the barrel dispensing head.

[0009] Preferably, the metering buffer cylinder has a cavity, and a pressing piston is provided in the cavity. The pressing piston is connected to a first driving mechanism, which drives the pressing piston to move in the metering buffer cylinder. A sealing ring is provided on the pressing piston, and the sealing ring is sealed to the inner wall of the metering buffer cylinder.

[0010] Preferably, the frame is provided with a dispensing bracket, the bottle dispensing head is installed at the bottom of the dispensing bracket, the dispensing head has a connector at the discharge end, and the bottle mouth of the bottled glue container is facing downward and matched with the connector.

[0011] Preferably, the top of the dispensing bracket is provided with an electric push rod, the bottom of which is connected to a positioning pressure plate, and the dispensing bracket is provided with a positioning stop.

[0012] Preferably, a placement platform is slidably installed below the frame, and the placement platform is connected to a second drive mechanism. The second drive mechanism drives the placement platform to move up and down, and the barrel-sized glue container is placed on the placement platform, with the barrel-sized dispensing head located above the placement platform.

[0013] The beneficial effects of this invention are as follows: By setting up a metering buffer cylinder and using a PLC control system to precisely control the position of the pressure piston inside the metering buffer cylinder, the invention accurately measures the amount of extruded glue, achieving precise metering of the extruded glue amount. This not only ensures accurate metering control but also facilitates convenient operation and adjustment. Furthermore, it eliminates the need for secondary transfer of the original large packaging to the equipment's storage tank, reducing pollution, waste, and cleaning costs during the transfer process. The invention employs a dual-layout configuration, allowing for the placement of large-capacity containers below and the installation of small-capacity bottles above, enabling selection of the appropriate container based on requirements. The machine can be used for both dispensing and filling, effectively solving the problems of poor versatility and inability to handle both bottles and barrels in existing equipment. When dispensing small-capacity bottles, the bottle body is sealed to the bottle mouth through the connector after installation, and the air inside the container can be gradually discharged from bottom to top to ensure that the air is completely emptied, effectively avoiding air bubbles trapped in the silicone and improving the quality of the dispensed product. When dispensing large-capacity barrels, the entire placement platform is first driven to move upwards in one go, and then the placement platform is driven to slowly descend in sync with the dispensing volume, so as to ensure that there is always no height difference between the dispensing port and the glue surface, effectively avoiding glue splashing and preventing air bubbles from being trapped.

[0014] The features and advantages of the present invention will be described in detail through embodiments and in conjunction with the accompanying drawings. Attached Figure Description

Detailed Implementation

[0017] See Figure 1 , Figure 2 , Figure 3 , Figure 4 A smart combination and packaging machine includes a frame 1, a metering buffer cylinder 2 on the frame 1, the metering buffer cylinder 2 being connected to a feeding unit via a conveying pipe 3, the metering buffer cylinder 2 being connected to a discharge pipe 4, the discharge end of the discharge pipe 4 being connected to a packaging head, the conveying pipe 3 being equipped with an inlet valve, and the discharge pipe 4 being equipped with a discharge valve.

[0018] The dispensing head includes a bottle dispensing head 5 and a barrel dispensing head 6. The discharge end of the bottle dispensing head 5 is arranged facing upwards, and the discharge end of the barrel dispensing head 6 is arranged facing downwards. The discharge end of the discharge pipe 4 is equipped with a quick switching mechanism, which can realize the switching of the passage of the discharge pipe 4, so that the discharge pipe 4 is connected to the bottle dispensing head 5 or the barrel dispensing head 6.

[0019] The quick switching mechanism includes a union elbow channel with quick-connect clamps at both ends. One end of the union elbow channel is connected to the discharge pipe 4, and the other end is connected to the bottle dispensing head 5 or the barrel dispensing head 6.

[0020] When switching modes, first open the quick-connect clamps to release the installation state of the union elbow, rotate the union elbow to adjust it to the appropriate position facing up or down, and then use the quick-connect clamps at both ends to connect the discharge pipe to the bottle dispensing head or the barrel dispensing head respectively to complete the quick connection and switching of the pipeline.

[0021] The quick-switching mechanism can also be a three-way valve.

[0022] The metering buffer cylinder 2 has a cavity inside, and the effective volume inside the metering buffer cylinder 2 is set as needed. This embodiment adopts a volumetric metering method.

[0023] The cavity is equipped with a pressing piston, which is connected to a first driving mechanism 11. The first driving mechanism 11 drives the pressing piston to move within the metering buffer cylinder 2. The pressing piston is equipped with a sealing ring, which is sealed to the inner wall of the metering buffer cylinder 2.

[0024] According to the cylinder volume formula V=S×L (V is the volume, S is the cross-sectional area of ​​the metering buffer cylinder, and L is the piston displacement distance), the inner diameter of the metering buffer cylinder is fixed, and the cross-sectional area S is a constant value. By controlling the piston's backward distance L, the metered silicone volume can be accurately controlled, and the error can be controlled within ±2%, meeting the accuracy requirements for small-capacity bottles.

[0025] The frame 1 is provided with a dispensing bracket 7, the bottle dispensing head 5 is installed at the bottom of the dispensing bracket 7, the dispensing end of the bottle dispensing head 5 is provided with a connector 8, and the bottle mouth of the bottled glue container 14 is facing downward and matched with the connector 8.

[0026] The top of the dispensing bracket 7 is provided with an electric push rod 13, the bottom of which is connected to a positioning pressure plate 9, and the dispensing bracket 7 is provided with a positioning stop.

[0027] In semi-automatic mode, the operator places the empty bottle at the positioning station below the dispensing head, aligning the bottle opening with the dispensing head outlet by touching the edge. Once in position, the operator lightly touches the sensor, which sends a signal to the control unit to start the dispensing process. This ensures that the bottle opening and the outlet are aligned, preventing silicone from spilling during the dispensing process.

[0028] A placement platform 10 is slidably installed below the frame 1. The placement platform 10 is connected to a second drive mechanism 12. The second drive mechanism 12 drives the placement platform 10 to move up and down. The barrel-sized glue container 15 is placed on the placement platform 10, and the barrel-sized dispensing head 6 is located above the placement platform 10.

[0029] Both the first and second drive mechanisms adopt servo screw transmission structures. The PLC controls the operation of the servo motor to precisely drive the corresponding components to adjust the lifting and lowering displacement. The motion stroke is controllable and the positioning accuracy is high.

[0030] The power and control unit uses compressed air and 380V, 50HZ voltage in the combined filling machine. The equipment power is 4.5KW as the main power source, and it is equipped with a servo motor to achieve precise control. The working principle is as follows: the compressed air is filtered, reduced and constant pressure module to output a stable pressure air source, which is supplied to the feeding pressure chamber, the cylinder driven valve and the piston drive mechanism. The air circuit is controlled by solenoid valve to realize the sequential switching of each action. The servo motor drives the ball screw to drive the piston movement. The piston displacement is precisely controlled by controlling the number of pulses of the servo motor to achieve precise volume control, with the volume of each bottle being ±2%.

[0031] The core of the control unit is a PLC programmable logic controller, which is pre-programmed with a dispensing control program. Operators can set parameters such as dispensing quantity, feeding speed, and discharging speed through a touch screen. The PLC controls the actions of each actuator according to the preset program based on the input signals from sensors (position sensor, weight sensor, photoelectric sensor), realizing the automated operation of the entire dispensing process. When faults such as insufficient feeding, dispensing deviation, or bottle jamming occur, the PLC will trigger an alarm screen and automatically stop the equipment, prompting the operator to handle the situation.

[0032] Working process of this invention: Initialization: The operator puts the 200L silicone drum filled with raw materials into the pressure silo, seals the silo, connects the discharge port to the conveying pipeline, and sets the dispensing volume, filling times, filling speed, etc. on the touch screen. After the equipment is started, compressed air enters the pressure silo to establish a constant feeding pressure. First, install the dispensing head onto the discharge end of the discharge pipe 4, and then connect the corresponding container to the discharge end; The operator places the empty bottle or empty bucket at the dispensing station, and the photoelectric sensor sends a positioning signal after detecting that the bottle is in place. The PLC controls the opening of the feed valve in the conveying pipeline and the closing of the discharge valve. The piston of the metering buffer cylinder retracts under the drive of the servo motor. The silica gel in the 200L barrel enters the metering buffer cylinder under pressure. When the piston retracts to the preset position corresponding to the capacity, the servo motor stops, the PLC closes the feed valve, and the metering is completed. The PLC controls the opening of the discharge valve, drives the pressing piston forward to squeeze, and transports the metered rubber material in the metering buffer cylinder 2 to the corresponding container. After the pressing piston moves to the position, the PLC controls the closing of the discharge valve. After the product is packaged, remove it, replace it with a new container, and begin the next packaging cycle.

[0033] When the raw materials in the 200L container are exhausted, the pressure sensor detects a drop in the supply pressure, triggering a material shortage alarm and prompting the operator to replace the 200L raw material container.

[0034] This combined dispensing mode compensates for the existing packaging specifications in the silicone production supply chain. It eliminates the need to transfer silicone from the original 200L bulk packaging to the equipment's storage tank, reducing pollution, waste, and cleaning costs during the transfer process. At the same time, the metering buffer tank precisely controls the dispensing volume, ensuring that the volume error of each bottle of finished product meets the standard requirements. It retains the cost advantage of large-package supply while meeting the quantitative requirements of small-bottle finished products. The entire equipment is designed to balance dispensing efficiency, dispensing accuracy, and ease of use, making it particularly suitable for the flexible application needs of users using mechanical automation and automatic dispensing construction.

[0035] After multiple rounds of repackaging tests, the repackaging and metering error of single bottles and single barrels of materials is controlled at around 1%, which meets the product specification requirements and complies with the outgoing quality inspection standards.

[0036] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the scope of protection of the present invention.
