[0002] Glue filling is a key piece of equipment that dispenses glue into glue tanks, including automatic filling machines, capping machines, and screw capping machines. These machines use automation technology to achieve quantitative filling and sealing of glue, improving production efficiency and product quality. The glue scraping mechanism is a process device used in glue filling to scrape off residual glue from the dispensing head, preventing glue from dripping onto the ground during production breaks, and sealing the dispensing head.

Traditionally, this involves manual scraping, using a scraper or spatula to remove excess glue from the container edges or surface. Improper operation can easily lead to dripping at the filling nozzle, leaving residue on the work surface and affecting its overall cleanliness. This method is labor-intensive, inefficient, and requires a high level of skill from the workers. Furthermore, the glue may contain harmful chemicals, posing a health risk to the workers. The inconvenience and hazards of manual glue scraping are problems that need to be addressed in the glue filling process. Utility Model Content

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easy to understand, the following embodiments, in conjunction with the accompanying drawings, will specifically illustrate the technical solution of this utility model.

[0020] See Figure 1 This utility model provides an automatic glue scraping device for a glue filling production line, including a column 2, a cylinder mounting plate 10, a cylinder mechanism, and a glue scraping mold.

[0021] The cylinder mounting plate 10 is fixed to the bottom of the column 2 using conventional methods such as bolts or welding. The cylinder mechanism includes a dual-axis cylinder 1 and a solenoid valve (not shown in the figure). The dual-axis cylinder 1 is mounted on the cylinder mounting plate 10. (See reference...) Figure 2 The dual-axis cylinder 1 has two piston rods 1a, and a fixing plate 1b is connected and fixed to the ends of the two piston rods 1a. A guide rod 1c is also fixed on the fixing plate 1b, and a guide hole for inserting the guide rod 1c is provided on the cylinder body of the dual-axis cylinder 1. When the dual-axis cylinder 1 operates, the piston rods 1a extend or retract into the cylinder body, driving the fixing plate 1b to move, and simultaneously driving the guide rod 1c to move in the guide hole. The air port of the solenoid valve is connected to the air port of the dual-axis cylinder 1, and the dual-axis cylinder 1 is controlled to operate by the solenoid valve. Preferably, the solenoid valve is a three-position five-way solenoid valve.

[0022] See Figure 2 The glue scraping mold includes a bracket 7 and a glue shovel 5. One end of the bracket 7 is connected and fixed to the fixing plate 1b, and the glue shovel 5 is fixed to the other end of the bracket 7.

[0023] The bracket 7 has a horizontal connecting plate 7a, a vertical plate 7b, and a reinforcing plate 7c. The vertical plate 7b is fixed to the upper surface of one end of the horizontal connecting plate 7a. The vertical plate 7b is used for mounting the bracket; specifically, the vertical plate 7b is bolted to the fixing plate 1b and tightened with a nut 8. Figure 2 As shown, in this embodiment, there are four sets of bolts and nuts, but this is not a limitation. In other embodiments, the number of bolt and nut assemblies can be set according to the actual situation. The two sides of the reinforcing plate 7c are respectively connected and fixed to the horizontal connecting plate 7a and the vertical plate 7b, improving the overall stability of the bracket structure.

[0024] The glue spatula 5 is fixed to the upper surface of one end of the horizontal connecting plate 7a. The glue spatula 5 has a bottom surface and three sides, and the spatula opening width of the glue spatula 5 is (e.g., ...). Figure 2 As shown, k) is greater than the outer diameter of the dispensing head 4.

[0025] A magnetic piece (not shown in the figure) is provided at the end of the guide rod 1c. The magnetic piece is fixed at the end of the guide rod 1c by adhesive or embedded fixing. See reference. Figure 3 A magnetic switch 11 is installed on the cylinder body of the dual-axis cylinder 1. The magnetic switch 11 is used to sense a magnetic plate. Since the magnetic plate is located at the end of the guide rod 1c, the magnetic switch 11 detects whether the guide rod 1c has retracted. (See reference...) Figure 1 When the glue spatula 5 moves away from the glue dispensing head 4 under the drive of the dual-axis cylinder 1, the guide rod 1c moves to the right and returns to the detection position of the magnetic switch 11. The magnetic switch detects the magnetic sheet and emits a sensing signal. The magnetic switch 11 is electrically connected to the PLC controller (not shown in the figure). The PLC controller is a commercially available product. PLC controllers typically have a CPU module, a DA module, and an AD module. The CPU module is the central processing unit, the DA module is the digital-to-analog converter, and the AD module is the analog-to-digital converter. The solenoid valve of the cylinder mechanism is electrically connected to the PLC controller, and the PLC controller controls the operation of the solenoid valve.

[0026] The upper end of the column 2 is fixed to the crossbeam 3 of the glue dispensing machine. A dispensing head 4 is connected to the lower part of the crossbeam 3, through which glue flows into the glue tank 6 below. The dispensing head 4 is located at the end of the travel stroke of the glue shovel 5. The shoveling surface of the glue shovel 5 is at the same horizontal level as the lower surface of the dispensing head; when the glue shovel 5 moves below the dispensing head 4, it will abut against the opening of the dispensing head 4.

[0027] The operation of the automatic glue scraping device for a glue filling production line according to this embodiment of the invention is as follows:

[0028] On the glue filling production line, glue bucket 6 is conveyed by a conveyor belt and stops below the filling head 4. The PLC controller controls the operation of the dual-axis cylinder 1, causing the piston rod 1a to move backward (see...). Figure 1 Moving from center to right, away from the dispensing head 4, the magnetic switch 11 senses the magnetic sheet and transmits the sensing signal to the PLC controller. The PLC controller then controls the piston rod 1a to stop moving. When the glue bucket 6 is conveyed by the conveyor belt and stops directly below the dispensing head 4, the dispensing machine is started, and the dispensing head 4 begins dispensing glue. After dispensing is complete, the PLC controller controls the dual-axis cylinder 1 to start, driving the glue scraper 5 to move and scrape off any remaining glue on the dispensing head 4, placing it below the dispensing head 4. The glue bucket 6 continues to be conveyed forward by the conveyor belt, away from the dispensing head 4. Then, the next glue bucket 6 is conveyed by the conveyor belt, and the above steps are repeated for dispensing and scraping.

[0029] The automatic glue scraping device for glue filling production line according to this utility model embodiment can realize the automated glue scraping work in the glue filling process, avoid manual operation, have a simple structure, save space, and effectively improve the production efficiency of the glue filling process.

[0030] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the scope of protection of this utility model.
