Description

Technical Field

[0001] This application belongs to the field of glue dispensing technology, specifically a dual-station glue dispensing machine. Background Technology

[0002] Adhesive dispensing machines are specialized equipment used to dispense liquid or paste-like viscous materials such as glues and adhesives into containers. They are widely used in industries that require large-scale glue processing, such as chemical, electronics, packaging, stationery, and building materials. Their core value lies in solving problems such as low efficiency, large dosage errors, material waste, and pollution associated with manual dispensing.

[0003] In existing technologies, during the dispensing process, the glue is usually stored in a dispensing container first, and then dispensed by squeezing the space inside the container. While this method is relatively simple, when filling the glue container, the glue needs to be poured into the dispensing container. During this process, dispensing cannot be performed, and the container must be filled before dispensing can begin again. This is time-consuming. Furthermore, during the process of pouring the glue from the glue container into the dispensing container, the glue comes into contact with air, which can easily lead to the formation of air bubbles inside the glue. Therefore, a dual-station glue dispensing machine needs to be designed to solve the above problems. Utility Model Content

[0004] The purpose of this application is to address the shortcomings of existing technologies by designing a dual-station glue dispensing machine that uses the method of "directly replacing the storage tank to achieve rapid replenishment," thereby solving the problems of "low efficiency and easy generation of air bubbles inside the glue when replenishing glue in existing technologies."

[0005] To achieve the above objectives, the following technical solution is adopted: A dual-station glue dispensing machine, including A support base, wherein a column is fixedly connected to the upper end of the support base, a top plate is fixedly connected to the upper end of the column, a sliding frame is slidably connected to the inner wall of the column, a sliding frame is provided on the inner wall of the top plate, and a hydraulic rod is installed at the upper end of the top plate; A liquid storage tank for storing glue is inserted into the inner wall of a sliding frame. A squeezing plate is fixedly connected to the lower end of the hydraulic rod output shaft. The piston of the squeezing plate is connected to the inner wall of the liquid storage tank. A diversion assembly is provided on the outer wall of the liquid storage tank. The lifting component, located on the inner wall of the support base, is used to control the up-and-down movement of the sliding frame; The control component, connected to the hydraulic rod and lifting assembly via signals, is used to control the operation of the hydraulic rod and lifting assembly.

[0006] Preferably, the lifting assembly includes a lifting motor, which is installed on the inner wall of the top plate. The lower end of the output shaft of the lifting motor is fixedly connected to a threaded rod, and the sliding frame is threadedly connected to the outer wall of the threaded rod.

[0007] Preferably, a guide rod is fixedly connected to the top of the sliding frame, and the guide rod passes through and is slidably connected to the inner wall of the top plate.

[0008] Preferably, the control component includes a central control box, which is connected to the lifting motor via a signal connection and to the hydraulic rod via a signal connection.

[0009] Preferably, a limit frame is installed on the front surface of the column, and a sensor is installed at the end of the limit frame near the liquid storage tank. The sensor is connected to the main control box via a signal.

[0010] Preferably, the main control box is electrically connected to an external switch via a wire.

[0011] Preferably, the diversion assembly includes a main flow valve, which is installed on the front surface of the liquid storage tank. A diversion pipe is installed at the front end of the main flow valve, and a diversion valve is installed at the end of the diversion pipe away from the main flow valve. A drain head is installed at the upper end of the diversion valve.

[0012] Preferably, the upper surface of the support base is provided with a groove, and the front end of the support base is provided with a ramp.

[0013] Compared with the prior art, the beneficial effects of this application are: 1. This application uses a sliding frame to move the liquid storage tank. When dispensing is required, the sliding frame can be used to move the liquid storage tank close to the hydraulic rod. In this way, the hydraulic rod can be used to squeeze the glue inside the liquid storage tank to achieve dispensing. After the glue inside the liquid storage tank is dispensed, the sliding frame can be directly controlled to move the liquid storage tank downward to the upper surface of the support base. In this way, the liquid storage tank can be directly replaced. This can reduce the time required to replenish glue and eliminate the need to repeatedly pour glue, thereby reducing the probability of glue bubbling.

[0014] 2. This application uses sensors and lifting devices to assist the operation of the device. During dispensing, the hydraulic rod can be controlled to squeeze the glue by stepping on an external switch, which is more convenient during operation. When changing the liquid storage tank, the height of the liquid storage tank can be detected by the sensor installed on the limit frame, which can prevent the liquid storage tank from rising too much and causing damage to the device.

[0017] Reference Figure 1 - Figure 4 A dual-station glue dispensing machine, including Support base 1: As the load-bearing foundation of the entire equipment, it provides stable support for all upper components. The upper end of the support base 1 is fixedly connected to the column 2. The column 2 is vertically connected to the edge of the support base 1, forming the frame structure of the equipment. At the same time, it provides a sliding track for the sliding frame 3 to ensure its stability when moving up and down. The upper end of the column 2 is fixedly connected to the top plate 4. The top plate 4 is fixed to the top of the column 2 by bolts to form a closed frame top. It is not only used to install the hydraulic rod 7, but also to protect the internal components from external interference. The inner wall of the column 2 is slidably connected to the sliding frame 3. The edge of the sliding frame 3 is precisely matched with the sliding groove of the inner wall of the column 2, and can move smoothly along the vertical direction of the column 2. The inner wall of the top plate 4 is provided with the sliding frame 3. The upper end of the top plate 4 is equipped with the hydraulic rod 7. The hydraulic rod 7 is fixed to the center of the top plate 4 by a flange. Its output shaft is vertically downward and can provide stable axial thrust to drive the extrusion plate 10 to complete the glue extrusion action. The storage tank 8 is used to store adhesive. The inner wall of the storage tank 8 is polished to reduce adhesive residue. It is inserted into the inner wall of the sliding frame 3. The bottom of the storage tank 8 is equipped with moving wheels, and there are slots between adjacent sets of moving wheels. The storage tank 8 can be locked into the inner wall of the sliding frame 3 by the slots. The lower end of the output shaft of the hydraulic rod 7 is fixedly connected to the extrusion plate 10. The piston of the extrusion plate 10 is connected to the inner wall of the storage tank 8. The diameter of the extrusion plate 10 matches the diameter of the inner wall of the storage tank 8. The edge is wrapped with an elastic sealing ring, which can fit tightly against the inner wall of the storage tank 8 to ensure that no adhesive leaks from the edge during extrusion. The outer wall of the storage tank 8 is equipped with a diversion component 9. The diversion component 9 is connected to the outlet of the storage tank 8 by threads, which can divert the adhesive in the storage tank 8 to multiple filling channels to achieve multi-station synchronous filling.

[0018] The lifting component 6 is located on the inner wall of the support base 1 and is used to control the up and down movement of the sliding frame 3. The core component of the lifting component 6 is hidden inside the support base 1, which not only saves equipment space but also protects the components from external collision damage.

[0019] The control component 5 is connected to the hydraulic rod 7 and the lifting component 6 via a signal to control the operation of the hydraulic rod 7 and the lifting component 6. The control component 5 communicates with each component via an industrial bus or wireless signal transmission, which has low signal delay and ensures timely command response.

[0020] In this embodiment, during use, the operator first opens the main flow valve 91 on the front surface of the storage tank 8, then opens the two branch flow valves 93 at the end of the branch pipe 92, inserts the container to be dispensed directly above the two drain heads 94, and then triggers filling through the main control box 51 or the external switch 54. The main control box 51 controls the hydraulic rod 7 on the top plate 4 to extend downward, driving the extrusion plate 10 to move in a piston-like manner along the inner wall of the storage tank 8, extruding the glue through the main flow valve 91, branch pipe 92, and branch valve 93 in sequence, and simultaneously flowing into the container from the two drain heads 94. When filling is completed, the external switch 54 or the main control box 51 can be released, thus ending the filling process.

[0021] Once the glue in the storage tank 8 has been dispensed, close the main flow valve 91 and the branch flow valve 93. The main control box 51 sends a signal to the lifting motor 63 of the lifting assembly 6. The lifting motor 63 reverses and drives the threaded rod 62 to rotate, causing the threaded sliding frame 3 to move downwards along the inner wall of the column 2 until the storage tank 8 is lowered to the inclined platform 101 of the support base 1. Then, the operator can remove the empty storage tank 8 along the inclined platform 101 at the front end of the support base 1, and then insert the new storage tank 8 filled with glue into the inner wall of the sliding frame 3. After the replacement is completed, the dispensing process can be restarted.

[0022] As a preferred embodiment, the lifting assembly 6 includes a lifting motor 63: the lifting motor 63 is a servo motor with high-precision speed control capability, which can change the lifting speed of the sliding frame 3 by adjusting the speed, and is suitable for liquid storage tanks 8 of different weights; the lifting motor 63 is installed on the inner wall of the top plate 4, and the lower end of the output shaft of the lifting motor 63 is fixedly connected to a threaded rod 62. The threaded rod 62 and the output shaft of the lifting motor 63 are connected by a coupling to ensure that the power transmission is without deviation. The sliding frame 3 is threadedly connected to the outer wall of the threaded rod 62. When the threaded rod 62 rotates, it can drive the sliding frame 3 to move along the axial direction of the threaded rod 62 to achieve smooth lifting.

[0023] As a preferred embodiment, a guide rod 61 is fixedly connected to the top of the sliding frame 3. The guide rod 61 is bolted to the sliding frame 3. The guide rod 61 passes through and is slidably connected to the inner wall of the top plate 4. A linear bearing is installed on the inner wall of the top plate 4 at the position corresponding to the guide rod 61 to reduce sliding friction resistance. The guide rod 61 can slide smoothly along the inner wall of the bearing and cooperates with the threaded rod 62 to form a guide, preventing the sliding frame 3 from rotating during the up and down movement.

[0024] As a preferred embodiment, the control component 5 includes a main control box 51, which is connected to the lifting motor 63 via a signal. The main control box 51 sends signals to the lifting motor 63 to control its forward and reverse operation and stop. The main control box 51 is also connected to the hydraulic rod 7 via a signal. The main control box 51 can control the extension / retraction speed and stroke of the hydraulic rod 7, and can also adjust the working state of the hydraulic rod 7 according to the signal from the sensor 53 to avoid overload.

[0025] As a preferred method, a limit frame 52 is installed on the front surface of the column 2. The limit frame 52 is fixed to the front surface of the column 2 by bolts, and its position corresponds to the highest working position of the liquid storage tank 8. The installation position can be flexibly adjusted according to the height of the liquid storage tank 8. A sensor 53 is installed at the end of the limit frame 52 near the liquid storage tank 8. The sensor 53 is an infrared photoelectric sensor or a proximity switch, which can detect the top position of the liquid storage tank 8 in real time. The sensor 53 is connected to the main control box 51 via a signal. When the liquid storage tank 8 rises to the preset height, the sensor 53 will immediately send a signal to the main control box 51 to stop the lifting motor 63 in time, so as to prevent the liquid storage tank 8 from rising too much and colliding with the top plate 4, causing damage to the equipment.

[0026] As a preferred embodiment, the diversion assembly 9 includes a main flow valve 91: the main flow valve 91 is a manually controlled valve installed on the main channel of the liquid outlet of the liquid storage tank 8, which can control the output of glue as a whole, making it convenient to close the channel when replacing the liquid storage tank 8 to prevent glue leakage. A diversion pipe 92 is installed at the front end of the main flow valve 91. The diversion pipe 92 adopts a multi-port structure, which can evenly distribute the glue in the main channel to each branch channel. A diversion valve 93 is installed at the end of the diversion pipe 92 away from the main flow valve 91. The diversion valve 93 can independently control the glue output of a single drain head 94, which is convenient to close some stations as needed during multi-station filling, improving operational flexibility. A drain head 94 is installed at the upper end of the diversion valve 93. The outlet diameter of the drain head 94 can be selected according to the size of the filling container, and it adopts a back-suction design, which can back-suction a small amount of glue after filling to prevent dripping and contamination of the container.

[0027] As a preferred embodiment, the diversion assembly 9 includes a main flow valve 91, which is mounted on the front surface of the liquid storage tank 8. A diversion pipe 92 is installed at the front end of the main flow valve 91, and a diversion valve 93 is installed at the end of the diversion pipe 92 away from the main flow valve 91. A drain head 94 is installed at the upper end of the diversion valve 93.

[0028] As a preferred method, the position of the groove 102 corresponds to the position of the sliding frame 3 after it is lowered, which can accommodate the sliding frame 3. The front end of the support base 1 is provided with a ramp 101, which allows the operator to easily move the liquid storage tank 8 up and down.
