Technical Field

[0001] This utility model relates to the field of dispensing machine technology, and more specifically, it relates to a protective device for dispensing machines. Background Technology

[0002] A dispensing machine is an automated device primarily used to precisely apply glue or other liquid materials onto products. Patent document CN208612914U discloses an automatic dispensing machine with a rotatable dispensing head, comprising a worktable, a sliding column, a crossbeam, and a dispensing head. Support legs are installed at the four corners of the worktable's bottom, and a housing is installed at the bottom of the worktable between the legs. A storage drawer is installed on one side of the housing, and a control box is installed on the housing on the side of the storage drawer. A dispensing platform is installed at the top of the worktable, and sliding grooves are provided on both sides of the top of the dispensing platform. Mounting plates are installed at both ends of the top of the dispensing platform, and sliders are installed on both sides of the bottom of the mounting plates, with the sliders connected to the sliding grooves. This invention, by installing sliding grooves and sliders, facilitates the adjustment of the distance between the two mounting plates, thereby facilitating the adjustment of the lateral horizontal spacing between the two sets of mounting plates.

[0003] However, the device lacks a protective device for the dispensing head. When the dispensing head is not in use, dust and impurities in the air can easily adhere to it. This causes the dispensing head to carry dust and impurities onto the product during the next use, affecting the transparency of the adhesive or causing spots on the surface after curing, thus reducing the quality of the dispensing. Secondly, after dispensing is completed, adhesive residue remains on the dispensing head. Under the influence of gravity, the residual adhesive easily drips, contaminating the worktable and requiring timely cleaning by staff, thereby increasing their workload. Utility Model Content

[0030] Please see Figures 1-5 A protective device for a dispensing machine includes a dispensing machine body 1, the dispensing machine body 1 including an operating table 2, a support base 3 movably mounted on the operating table 2, the support base 3 being L-shaped, an electric push rod 4 mounted on the support base 3, a lifting plate 5 fixedly mounted on the driving end of the electric push rod 4 passing through the support base 3, a dispensing head 6 mounted on the lifting plate 5, a movable groove 7 on one side of the support base 3, two movable grooves 7, a bidirectional lead screw 8 rotatably mounted in each of the two movable grooves 7, a motor 9 fixedly mounted on one end of each bidirectional lead screw 8 passing through the support base 3, the motor 9 being fixedly mounted on the support base 3, a movable seat 10 threadedly connected to the bidirectional lead screw 8, two movable seats 10, a first protective shell 11 and a second protective shell 12 fixedly mounted on one end of each movable seat 10 passing through the movable groove 7.

[0031] In this embodiment, when dispensing is required, the motor 9 is started, and the motor 9 drives the bidirectional lead screw 8 to rotate. The bidirectional lead screw 8 has two threaded areas with opposite directions, which causes the two moving seats 10 to move in the direction of separation. The two moving seats 10 respectively drive the first protective shell 11 and the second protective shell 12 to move, so that the dispensing head 6 is exposed. The electric push rod 4 is started, and the electric push rod 4 drives the lifting plate 5 to move downward. The lifting plate 5 drives the dispensing head 6 to move downward to dispense the glue. After the dispensing is completed, the reverse operation can be used to make the first protective shell 11 and the second protective shell 12 cooperate to protect the dispensing head 6. At this time, the two moving seats 10 are in contact with the two ends of the lifting plate 5.

[0032] Please see Figures 1-5 As one embodiment of moving the support base 3: the operating table 2 is provided with a first electromagnetic slide rail 14, and there are two first electromagnetic slide rails 14. A first sliding seat 15 is slidably provided on the first electromagnetic slide rail 14. A bracket 16 is fixedly provided on the two first sliding seats 15. A second electromagnetic slide rail 17 is provided on the bracket 16. A second sliding seat 18 is provided on the second electromagnetic slide rail 17. The second sliding seat 18 is fixedly connected to the support base 3.

[0033] Specifically, the bracket 16 is moved by the cooperation of the first electromagnetic slide rail 14 and the first sliding seat 15, while the second electromagnetic slide rail 17 and the second sliding seat 18 are used to adjust the position of the support 3, thereby driving the dispensing head 6 to move to the position of dispensing as needed.

[0034] Please see Figures 1-5 As one embodiment for collecting dripping glue: a collection box 13 is installed on the first protective shell 11, and limiting shells 19 are fixed on both sides of the collection box 13. A push plate 20 is movably installed inside the limiting shell 19, and the lower end of the push plate 20 extends to the outside of the limiting shell 19. A spring 21 is provided between the push plate 20 and the limiting shell 19. An insertion rod 22 is fixed on one side of the push plate 20. One end of the insertion rod 22 passes through the limiting shell 19 and is inserted into the first protective shell 11. The first protective shell 11 is provided with an installation groove 23, and the installation groove 23 cooperates with the collection box 13, the limiting shell 19 and the insertion rod 22.

[0035] Specifically, when the first protective shell 11 and the second protective shell 12 come into contact to protect the dispensing head 6, the collection box 13 can collect the dripping glue. When the collection box 13 needs to be disassembled and cleaned, the two push plates 20 are pushed while the first protective shell 11 and the second protective shell 12 are separated. The push plates 20 drive the insertion rod 22 to move, so that the insertion rod 22 moves out of the first protective shell 11. The spring 21 is compressed, pushing the push plate 20 upward. The push plate 20 drives the limiting shell 19 and the collection box 13 to move upward, so that they are moved out of the mounting groove 23, thereby the collection box 13 can be removed for cleaning.

[0036] Please see Figures 1-5 As one embodiment of cleaning the collection box 13: a rotating ring 24 is provided on the outside of the collection box 13 via a bearing, and a connecting arm 25 is fixedly provided inside the rotating ring 24. There are two connecting arms 25, and a scraper 26 is fixedly provided between the two connecting arms 25. The scraper 26 is U-shaped.

[0037] Specifically, when it is necessary to clean the adhesive in the collection box 13, during the process of pouring out the adhesive collected in the collection box 13, the rotating ring 24 is rotated so that the rotating ring 24 rotates around the rotating connection with the collection box 13. The rotating ring 24 drives the two connecting arms 25 to rotate, and the connecting arms 25 drive the scraper 26 to rotate, so that the scraper 26 scrapes and cleans the adhesive that has dried or adhered to the collection box 13, so that it can be poured out together.

[0038] In summary, when using the overall equipment:

[0039] When the dispensing head 6 needs protection, the first electromagnetic slide rail 14 and the first sliding seat 15 cooperate to move the bracket 16. At the same time, the second electromagnetic slide rail 17 and the second sliding seat 18 cooperate to adjust the position of the support 3, thereby driving the dispensing head 6 to move to the required dispensing position. The motor 9 is started, and the motor 9 drives the bidirectional lead screw 8 to rotate. The bidirectional lead screw 8 has two threaded areas with opposite directions, causing the two moving seats 10 to move in the separation direction. The two moving seats 10 respectively drive the first protective shell 11 and the second protective shell 12 to move, so that the dispensing head 6 is exposed. The electric push rod 4 is started, and the electric push rod 4 drives the lifting plate 5 to move downward. The lifting plate 5 drives the dispensing head 6 to move downward to dispense glue. After the glue is dispensed, the reverse operation can be used to make the first protective shell 11 and the second protective shell 12 cooperate to protect the dispensing head 6. At this time, the two moving seats 10 are in contact with the two ends of the lifting plate 5. The operating table 2 is equipped with components such as a booster pump and a storage tank to ensure the operation of the dispensing machine body 1. Since the process and principle of dispensing glue from the dispensing head have been disclosed in the patent with announcement number CN208612914U entitled "An Automatic Dispensing Machine with Rotatable Dispensing Head", its specific structure and working principle will not be described in detail here.

[0040] When it is necessary to collect the adhesive residue on the dispensing head 6, the collection box 13 can collect the dripping adhesive when the first protective shell 11 and the second protective shell 12 are in contact to protect the dispensing head 6. When it is necessary to disassemble and clean the collection box 13, the two push plates 20 are pushed when the first protective shell 11 and the second protective shell 12 are separated. The push plates 20 drive the insertion rod 22 to move, so that the insertion rod 22 moves out of the first protective shell 11. The spring 21 is compressed, pushing the push plates 20 upward. The push plates 20 drive the limiting shell 19 and the collection box 13 to move upward, so that they are moved out of the mounting groove 23, thereby allowing the collection box 13 to be removed for cleaning.

[0041] When the collection box 13 needs to be cleaned, the disassembled collection box 13 is tilted to allow the adhesive inside to flow out. During this process, the rotating ring 24 is rotated around the rotating connection point with the collection box 13. The rotating ring 24 drives the two connecting arms 25 to rotate, and the connecting arms 25 drive the scraper 26 to rotate. The scraper 26 scrapes and cleans the adhesive that has dried or adhered to the collection box 13, so that it can be poured out together.

[0042] The control panel 2 is equipped with a controller to control the electrical equipment on the dispensing machine and the entire protective device. Since the equipment matched with the controller is a common device, its control principle and wiring connection are existing, well-known and mature technologies. Therefore, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0043] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
