[0023] The meanings of the labels in the figures are as follows.

[0024] Detailed Implementation The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0025] like Figures 1 to 3 This is a simple adhesive cleaning device for dispensing machines, designed for convenient cleaning of the dispensing head. The device includes a housing 1, manufactured using a metal material such as cold-rolled steel plate, and treated with rust prevention to extend its service life. The housing 1 has a rectangular structure to accommodate the pre-set installation space of the dispensing machine. A cleaning port 2 is provided at the top of the housing 1. This rectangular opening is wider than or equal to the width of the adhesive strip 8 (mentioned later). This design ensures that the dispensing head can fully contact the adhesive strip 8 during subsequent cleaning, preventing any omissions. Furthermore, a rectangular groove is formed along the vertical direction on the inner wall of the housing 1, its cross-section matching the shape of the left and right edges of a partition 3, ensuring that the partition 3 can be fully embedded to achieve spatial separation. During assembly, the partition 3 is embedded in the groove, and a stable connection is achieved with the equipment housing 1 through the groove. This connection method not only facilitates the installation and disassembly of the partition 3, but also ensures that the partition 3 does not shake during equipment operation. The partition 3 divides the interior of the equipment housing 1 into two independent spaces, front and rear. The front space is for material storage. A removable door panel can be installed on the front wall of the material storage space for easy replacement of the adhesive application strip 8. The rear space is for control. A contact adjustment block 4 is installed on the partition 3 directly below the cleaning pre-reservation port 2. Specifically, the contact adjustment block 4 is installed on the side of the partition 3 facing the material storage space to ensure that its mating position with the adhesive application strip 8 matches the layout of the front material storage space. The contact adjustment block 4 consists of a block-shaped body made of hard plastic, possessing a certain degree of wear resistance to prevent deformation over long-term use. Furthermore, a contact groove 12 is formed at the upper end of the block body. The shape of the contact groove 12 is adapted to the direction of the adhesive application strip 8, allowing the adhesive application strip 8 to run smoothly against the surface of the contact groove 12. Additionally, when the dispensing head is inserted into the cleaning pre-reservation port 2, it provides adequate deformation space for the adhesive application strip 8 to be pressed down, preventing undue tearing of the adhesive application strip 8 due to pressure. Furthermore, several adjustment holes 5 are provided on the block body. These adjustment holes 5 are oblong holes arranged in pairs, with their length direction set vertically. The contact adjustment block 4 is connected to the partition plate 3 through adjustment screws passing through the adjustment holes 5. The operator can loosen the adjustment screws and move the contact adjustment block 4 up and down along the length direction of the oblong holes to adjust the contact pressure between the adhesive strip 8 and the dispensing head of the dispensing machine, so as to adapt to the cleaning needs of different dispensing scenarios. The contact adjustment block 4 is located at the upper end and is suitable for cleaning the end face of the dispensing head of the flat nozzle type. The contact adjustment block 4 is located at the lower end and is suitable for the wrap-around cleaning of the dispensing head of the immersion needle type. In addition, the edges of the contact groove 12 are all machined with rounded chamfers. These rounded chamfers can prevent the adhesive strip 8 from being scratched by the edge of the contact groove 12 during operation and extend the service life of the adhesive strip 8. Meanwhile, a buffer block is filled inside the contact groove 12. The buffer block is a silicone block. The silicone block has a certain elasticity and can play a buffering role when the adhesive strip 8 comes into contact with the dispensing head, which can both ensure the cleaning effect and prevent the dispensing head from being damaged by rigid collision. On one side of the partition 3 located in the storage space (i.e., the front side of the partition 3), a feeding mechanism 6 and a winding mechanism 7 are respectively installed. The feeding mechanism 6 and the winding mechanism 7 have similar structures, both including a rotating shaft 13 movably connected to the partition 3. The rotating shaft 13 is connected to the partition 3 through bearings to ensure smooth rotation of the rotating shaft 13 and reduce frictional resistance. At the same time, a material roller is fixedly installed on the rotating shaft 13. The material roller is used to wind the adhesive strip 8. The material roller of the feeding mechanism 6 winds unused adhesive strip 8, and the material roller of the winding mechanism 7 is used to wind up the used and soiled adhesive strip 8. A limiting component is also installed on the material roller. The limiting component has two specific implementation forms: the first is an adhesive ring 14 distributed around the periphery of the material roller. The adhesive ring 14 can adhere to the adhesive strip 8 to achieve roll splicing and prevent loosening. The second type is a strip clamp mainly installed on the material roller of the winding mechanism 7. The strip clamp is an adjustable clamp structure that can hold one end of the adhesive strip 8 to achieve limiting docking during winding. In this way, appropriate tension can be provided to the adhesive strip 8 to avoid winding failure. In order to improve the tension effect of the adhesive strip 8, several tensioning rollers 11 are also provided on one side of the partition 3 located in the material storage space, which are in contact with the adhesive strip 8.

[0026] On one side of the partition 3 located in the control space (i.e., the rear side of the partition 3), corresponding to the positions of the feeding mechanism 6 and the winding mechanism 7, a feeding drive device and a winding drive device (not shown in the figure) are respectively installed, both of which are motors. During implementation, stepper motors of the same model can be selected to ensure synchronous speed adjustment and avoid the wiping tape 8 from becoming loose or overstretched. The feeding drive device is fixed to the partition 3 by a motor bracket, and its output shaft is connected to the rotating shaft 13 of the feeding mechanism 6 through a coupling, which is used to drive the rotating shaft 13 and the material roller of the feeding mechanism 6 to rotate, thereby releasing the wiping tape 8. During installation, a cross-slider type coupling is selected to adapt to the transmission requirements in the front and rear directions and ensure stable power transmission. At the same time, the winding drive device is also fixed to the partition 3 by an independent motor bracket, and its output shaft is connected to the rotating shaft 13 of the winding mechanism 7 through another set of couplings of the same specifications, which is used to drive the rotating shaft 13 and the material roller of the winding mechanism 7 to rotate, thereby winding the wiping tape 8 after use. According to a preferred embodiment of this utility model, a control device 9 is also installed on the side of the partition 3 located in the control space (i.e., the rear side of the partition 3). Specifically, the control device 9 is a PLC module or a microcontroller module. The PLC module is suitable for complex control scenarios and can realize precise linkage adjustment of the feeding and receiving speeds. The microcontroller module is suitable for simple control needs, meeting basic start / stop and speed synchronization control, and can be selected according to equipment cost and functional requirements. During assembly, the control device 9 is installed on the partition 3 through a fixed base, and the control device 9 is electrically connected to the feeding drive device and the receiving drive device through independent wires, which can independently realize the start / stop control of the two drive devices, and at the same time, can synchronously adjust the speed of the two to ensure that the feeding and receiving speeds are matched and maintain constant tension of the wiping tape 8 during operation. At the same time, a communication interface is provided on one side wall of the equipment housing 1. The diameter of the communication interface is adapted to the standard communication terminal 15, and the communication terminal 15 is fixedly installed on the communication interface. To facilitate interfacing with communication control equipment compatible with the dispensing machine and improve versatility, the communication terminal 15 used in this invention can be an RS485 communication terminal 15, which features strong anti-interference capability and long transmission distance. Alternatively, an OB interface or other COM interface can also be used. Furthermore, the communication terminal 15 can be directly integrated with a power supply. During implementation, the communication terminal 15 is electrically connected to the control device 9 via a wire. Operators can connect the control device 9 to external devices such as the dispensing machine control system or a computer through the communication terminal 15, enabling the transmission of equipment operating data, such as feeding speed, receiving speed, and remaining tape quantity, as well as the reception of external control commands, thereby enhancing the intelligence level of the equipment. Furthermore, this utility model includes a control component 10 installed on the outer wall of the equipment housing 1. The control component 10 is a button. Depending on the actual control needs, it may include one or more of the following: a main start button, a main stop button, a feeding speed adjustment button, and a rewind speed adjustment button. The control component 10 is electrically connected to the control device 9 via wires. The operator can send commands to the control device 9 by pressing the buttons: pressing the main start button, the control device 9 simultaneously starts the feeding drive device and the rewind drive device, driving the adhesive strip 8 to complete the coordinated operation of release and rewind; pressing the main stop button, the control device 9 simultaneously stops the two drive devices; the feeding speed adjustment button or the rewind speed adjustment button can be used to adjust the speed of the feeding drive device or the rewind drive device respectively, flexibly adapting to the operating requirements of adhesive strips 8 with different thicknesses, making the operation convenient and intuitive. The working principle of this utility model is as follows: First, open the detachable door panel on the front side of the storage space, and lead the adhesive strip 8 out from the material roller of the feeding mechanism 6. Pass it sequentially through the contact groove 12 of the contact adjusting block 4, the cleaning reserved opening 2 at the upper end of the equipment housing 1, and then fix it on the material roller of the winding mechanism 7. Close the door panel. By adjusting the position of the contact adjusting block 4, the adhesive strip 8 maintains a suitable contact state with the dispensing components of the dispensing machine. Then, the operator starts the equipment through the main start button of the control component 10. The control device 9 synchronously drives the feeding drive and the receiving drive. The feeding drive drives the feeding mechanism 6 to release the adhesive strip 8, and the receiving drive drives the winding mechanism 7 to synchronously rewind the used adhesive strip 8. After the dispensing machine completes one dispensing cycle, the adhesive strip 8 cleans the conveyed dispensing head under constant tension. Throughout the process, the feeding and receiving speeds can be adjusted in real time via the speed adjustment button to ensure cleaning effect and strip running stability, achieving continuous and stable adhesive application.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
