Description

Technical Field

[0001] This utility model relates to the field of pad printing technology, specifically to a quick-change device for pad printing heads with cleaning function. Background Technology

[0002] Plastic toys are toys designed for children under 14 years old, made primarily of plastic materials, and not powered by electricity. The main component of plastic toys is high-molecular synthetic resin (polymer). This material has plasticity and fluidity under specific temperature and pressure, allowing it to be molded into a certain shape and maintain that shape under certain conditions.

[0003] Sometimes, patterns need to be printed on the surface of plastic toys during the production process. This is generally done using a pad printing machine. For example, Chinese patent CN103240968A discloses a pad printing machine head, including a head body composed of a frustum and an inverted "V" shaped portion. A retaining ring is provided in the middle of the head, and a locator is provided at the bottom of the inverted "V" shaped portion. The head also includes a shaft hole through which it connects to a corresponding shaft, and the locator is connected to the power supply of the pad printing machine via a wire. This device, by using a retaining ring, can effectively prevent excessive deformation of the pad printing head, improving the aesthetics and clarity of the pattern. Simultaneously, the locator ensures accurate positioning of the pad printing head, avoiding reprinting. However, it still has the following drawbacks: The rubber head cannot be cleaned easily and evenly, leaving room for improvement. Summary of the Invention

Figures 1-4 As shown, it includes: a movable frame 100, with mounting holes 111 symmetrically opened on the top of the movable frame 100, a connecting mechanism 200 for mounting a pad printing head 112 on the movable frame 100, a connecting frame 210 fixedly connected to the pad printing head, and a cleaning mechanism 300 on the movable frame 100; the cleaning mechanism 300 includes a liquid storage tank 310 fixedly connected to the movable frame 100, a delivery pipe 314 fixedly connected to the surface of the pad printing head 112, a plurality of nozzles 315 evenly distributed on the surface of the delivery pipe 314, a water pump 311 fixedly connected to the top of the liquid storage tank 310, and the outlet of the water pump 311 being connected to the delivery pipe 314 through the delivery pipe 312.

[0020] A quick-change device for a pad printing head with a cleaning function, using the above-mentioned technical solution, is provided with a cleaning mechanism 300. A water pump 311 extracts the cleaning agent and water from the storage tank 310, respectively, and sends the cleaning agent and water into the infusion channel 313 through the infusion pipe 312, and finally into the delivery pipe 314. The cleaning agent and water are sprayed onto the pad printing head 112 through the nozzle 315, and the pad printing head 112 is cleaned by the cleaning agent and water.

[0021] To clean the pad printing head 112, two liquid storage tanks 310 are symmetrically arranged on both sides of the movable frame 100. The two liquid storage tanks 310 contain cleaning solution and clean water, respectively. The ink is first cleaned with the cleaning solution, and then rinsed with clean water to improve the cleaning effect.

[0022] In order to replenish the cleaning fluid and water, the top of the storage tank 310 is provided with a filling port, and the connecting frame 210 is provided with a delivery channel 313 corresponding to the delivery tube 312.

[0023] In order to thoroughly clean the pad printing head 112, the printhead 315 is positioned facing the bottom of the pad printing head 112.

[0024] To facilitate quick replacement of the pad printing head 112, the connecting mechanism 200 includes a limiting plate 211 fixedly connected to the surface of the connecting frame 210, and a locking nut 212 is provided on the surface of the connecting frame 210.

[0027] In summary, the quick-change device for a pad printing head with a cleaning function provided in this embodiment has the following advantages: a cleaning mechanism 300 is provided, in which a water pump 311 extracts the cleaning agent and water from the storage tank 310, and sends the cleaning agent and water into the infusion channel 313 through the infusion pipe 312, and finally into the delivery pipe 314, and sprays them onto the pad printing head 112 through the nozzle 315, thereby cleaning the pad printing head 112 with the cleaning agent and water.

[0028] In use, the moving frame 100 is fixed to the pad printing machine with fixing bolts and mounting holes 111. The moving frame 100 is moved by the cylinder, thereby moving the pad printing head 112 to perform pad printing. When the pad printing is unclear, the water pump 311 is started to extract the cleaning solution and water in the storage tank 310 in sequence. First, the cleaning solution is sprayed out through the nozzle 315 to rinse the pad printing head 112, and then clean water is sprayed out to clean the pad printing head 112 to avoid cleaning solution residue. After cleaning, it is air-dried and the pad printing operation continues.
