Description

Technical Field

[0001] This utility model belongs to the field of patching machine technology, specifically relating to a patching device with buffer. Background Technology

[0002] A patch applicator is a device that accurately and efficiently applies specific patches to the surface of a target object. It is widely used in many fields such as medical, daily chemical, and food industries.

[0003] Chinese Patent CN218807177U discloses an automatic telescopic labeling head device, including a labeling head main board. One side of the main board is provided with a film receiving tray, a swing arm, a rotating roller, a pressure roller, a guide roller, and a label tray. The labeling film passes sequentially through the label tray, the guide roller, and one end of the rotating roller and is wound onto the film receiving tray. The pressure roller is slidably disposed in an adjustment hole at one end of the main board via a connecting shaft, and a spacing adjustment mechanism is installed at one end of the connecting shaft. This invention utilizes the spacing adjustment mechanism at one end of the pressure roller's connecting shaft. The spacing adjustment mechanism includes an adjustment plate, both ends of which are slidably engaged in the limiting grooves of a guide seat. A servo motor is connected to one side of the adjustment plate via a rack and pinion gear set, enabling the servo motor and rack and pinion gear set to drive the adjustment plate to move and adjust the spacing between the pressure roller and the rotating roller, thereby meeting the processing requirements of film of different thicknesses.

[0004] The device uses a gear and rack transmission system with high steel performance, which places strict requirements on the suction nozzle. It is only suitable for suction nozzles with built-in cushioning. Otherwise, it may damage the product or cause the label to be applied in place. In addition, suction nozzles with built-in cushioning are prone to loss of application accuracy.

[0005] Based on this, we designed a cushioned application device. Utility Model Content

[0006] The purpose of this invention is to address the poor adaptability of existing labeling devices by providing a cushioned labeling device.

[0007] This utility model is achieved through the following technical solution:

[0013] A spring is fitted onto the guide screw, with one end of the spring inserted into the countersunk hole of the adjusting block and the other end pressing against the outer wall of the U-axis mounting base.

[0014] In a preferred embodiment of the cushioned patching device provided by this utility model, the blocking plate is fixedly connected to the end of the adjusting screw.

[0015] In a preferred embodiment of the cushioned application device provided by this utility model, the diameter of the blocking plate is smaller than the inner diameter of the countersunk hole and larger than the outer diameter of the spring.

[0016] In a preferred embodiment of the cushioned application device provided by this utility model, the slide rail is fixedly mounted on the cushioning device mounting base by screws.

[0017] In a preferred embodiment of the cushioned application device provided by this utility model, the slider is slidably mounted on the slide rail to ensure the smooth application of the material by the slider.

[0018] In a preferred embodiment of the cushioned application device provided by this utility model, a pad is also provided between the guide screw and the fixing block and the U-axis mounting seat.

[0019] This invention has the following advantages over the prior art:

[0020] 1. This device can adapt to hard-connected suction nozzles, ensuring cushioning while guaranteeing application accuracy through a pre-pressurized slider; the impact force during application is absorbed by spring buffering, protecting the motor driving the downward application and preventing motor overload alarm.

[0021] 2. This device utilizes the self-adaptive ability of springs to maintain a uniform application height even with varying application heights within a certain range, eliminating the need for frequent height adjustments. Attached Figure Description
