Description

Technical Field

[0001] This utility model relates to the field of pressure-sensitive gasket manufacturing technology, and in particular to a device for adjusting the wax coating thickness of pressure-sensitive gaskets. Background Technology

[0002] Pressure-sensitive gaskets, also known as pressure-sensitive pads, are a type of sealing material widely used in the packaging industry. They are typically made of polystyrene foam, which is lightweight and elastic. This material can deform itself to fit tightly against the bottle opening, providing basic sealing support.

[0003] The main functions of waxing pressure-sensitive gaskets are to enhance sealing, improve adaptability, optimize user experience, and extend shelf life. Its core function is to achieve reliable sealing through pressure sensing. Widely used in the packaging industry, the wax layer forms a dense physical barrier on the surface of the pressure-sensitive gasket, effectively preventing external air, moisture, and microorganisms from penetrating the packaging, thus protecting the contents from contamination or spoilage. During the coating process, the wax can penetrate into the tiny gaps between the pressure-sensitive gasket and the bottle opening, filling uneven surfaces and further improving the sealing effect. The wax layer has a certain degree of thermal stability, maintaining stable physical and chemical properties within a certain temperature range, thus adapting to packaging needs in different environments. For example, in high-temperature environments, the wax layer does not easily soften or flow; in low-temperature environments, the wax layer does not easily crack or peel off.

[0004] When applying wax to existing pressure-sensitive gaskets, operators usually do it manually. However, during the waxing process, it is impossible to accurately control the thickness of the wax coating on the surface of the pressure-sensitive gasket, and the accuracy and processing efficiency need to be improved. Utility Model Content

[0005] The purpose of this invention is to solve the problem that when applying wax to pressure-sensitive gaskets, operators usually apply the wax manually, and it is difficult to accurately control the thickness of the wax coating on the surface of the pressure-sensitive gasket during the waxing process, resulting in a need to improve accuracy and processing efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a pressure-sensitive gasket wax coating thickness adjustable device, comprising a main body, a spraying assembly on the top of the main body, the spraying assembly including a wax storage tank, a flow sensor connected to the bottom of the wax storage tank, a servo motor connected to one outer surface of the flow sensor, a one-way screw connected to the output end of the servo motor, a sliding rod inserted into the front end of the wax storage tank, a receiving cylinder provided directly below the flow sensor, movable blocks connected to both sides of the receiving cylinder, sliding holes and threaded holes respectively opened inside the two sets of movable blocks, a pump body connected to the bottom of the receiving cylinder, a nozzle connected to the bottom of the pump body, a placement frame slidably connected to the bottom of one side of the main body, a gasket body connected to the surface of the placement frame, a PLC controller connected to the other side of the main body, and a transparent PVC plate connected to the front end of the main body.

[0007] Furthermore, the PLC controller is electrically connected to an external power supply via a control switch, and is also electrically connected to the flow sensor, servo motor, and pump body.

[0008] Furthermore, the output end of the servo motor is fixedly connected to the one-way screw, and the one-way screw is threadedly connected to the moving block through a threaded hole.

[0009] Furthermore, the slide bar forms a sliding connection with the moving block through a sliding hole.

[0010] Furthermore, the top of the wax storage tank is connected to an anti-solidification component, which includes a top cover, a stirring motor connected to the top of the top cover, and a feed inlet connected to the top of one side of the top cover.

[0011] Furthermore, a heating wire is installed inside the wax storage tank, and a stirring rod is connected to the output end of the stirring motor.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, when waxing the gasket body, the required option can be selected on the PLC controller according to the actual required thickness. Then, the wax storage tank will automatically flow into the corresponding wax into the receiving cylinder. At the same time, under the action of the unidirectional screw, the nozzle will move in the opposite direction, thereby achieving the effect of uniformly spraying wax on multiple gasket bodies at the same time. After the wax is sprayed, the receiving cylinder will automatically move to one side to wait for the next use. Thus, by controlling the amount of wax, the thickness of the wax coating on the surface of the pressure-sensitive gasket can be controlled, thereby improving the processing efficiency of the gasket body.

[0013] 2. In this utility model, after the wax is poured into the wax storage tank, the stirring motor can be turned on to drive the stirring rod to rotate, thereby stirring the wax inside the wax storage tank. With the heating effect of the heating wire, the wax solidifies, ensuring the stability during spraying. Attached Figure Description

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1, such as Figure 1 - Figure 3As shown, this utility model provides a device for adjusting the wax coating thickness of pressure-sensitive gaskets, including a main body 1. A spraying assembly 2 is mounted on the top of the main body 1. The spraying assembly 2 includes a wax storage tank 201. A flow sensor 202 is connected to the bottom of the wax storage tank 201. A servo motor 203 is connected to one outer surface of the flow sensor 202. A one-way screw 204 is connected to the output end of the servo motor 203. A sliding rod 205 is inserted into the front end of the wax storage tank 201. A receiving cylinder 206 is located directly below the flow sensor 202. Moving blocks 207 are connected to both sides of the receiving cylinder 206. The two sets of moving blocks 207 have sliding holes 208 and threaded holes 209 respectively inside. A pump body 210 is connected to the bottom of the receiving cylinder 206. The device body 1 is connected to a nozzle 211. A placement rack 212 is slidably connected to the bottom of one side of the device body 1. A pad body 213 is connected to the surface of the placement rack 212. A PLC controller 214 is connected to the other side of the device body 1. A transparent PVC board 215 is connected to the front end of the device body 1. The PLC controller 214 is electrically connected to an external power supply through a control switch. The PLC controller 214 is electrically connected to the flow sensor 202, the servo motor 203, and the pump body 210. The output end of the servo motor 203 is fixedly connected to the one-way screw 204. The one-way screw 204 is threadedly connected to the moving block 207 through the threaded hole 209. The slide rod 205 is slidably connected to the moving block 207 through the sliding hole 208.

[0019] The effect achieved in Embodiment 1 is as follows: First, the gasket bodies 213 to be sprayed are neatly arranged on the surface of the placement rack 212, ensuring stable placement and uniform spacing, providing a stable foundation for subsequent spraying operations. Then, the placement rack 212 carrying the gasket bodies 213 is smoothly slid into the main body 1 of the equipment, bringing it to the preset spraying position. At this point, the operator can accurately select the required wax coating thickness option on the PLC controller 214 according to actual production needs. After receiving the instruction, the PLC controller 214 immediately sends a control signal to the flow sensor 202 of the wax storage tank 201, triggering the automatic opening of the solenoid valve at its bottom. Under the action of gravity, the wax liquid in the wax storage tank 201 flows into the receiving cylinder 206 through the solenoid valve. During the wax liquid flow process, the flow sensor 202 monitors the inflow rate in real time. When the inflow reaches the preset value, the flow sensor 202 immediately senses and sends a signal to the PLC controller 214. The PLC controller 214 then controls the solenoid valve to close, completing the precise receiving of the material in the receiving cylinder 206 and ensuring the accurate amount of wax used for each spray. After receiving, the PLC controller 214 automatically starts the stirring motor 302. The output of the stirring motor 302 drives the one-way screw 204 to start rotating. The one-way screw 204, through its external thread, engages with the threaded hole 209 on the moving block 207, converting the rotational motion into linear motion, thereby moving the receiving cylinder 206 along the axial direction of the one-way screw 204 to directly above the placement rack 212. When the receiving cylinder 206 reaches the designated position, the PLC controller 214 activates the pump body 210. The pump body 210 pressurizes and delivers the wax in the receiving cylinder 206 to the spray head 211, which then begins to spray multiple sets of gasket bodies 213 on the placement rack 212 simultaneously. With the continuous rotation of the unidirectional screw 204, the moving block 207 drives the receiving cylinder 206 and the nozzle 211 to move back and forth, ensuring that the wax liquid can evenly cover the surface of each gasket body 213, achieving an efficient and uniform spraying effect. After the wax liquid is sprayed, the PLC controller 214 controls the stirring motor 302 to reverse, driving the receiving cylinder 206 to automatically move to the standby position on the side of the equipment, waiting for the next spraying operation. The entire spraying process, through the precise control of the wax amount, spraying position and movement path by the PLC controller 214, not only achieves precise control of the wax coating thickness on the pressure-sensitive gasket surface, but also significantly improves the processing efficiency of the gasket body 213, meeting the needs of large-scale production.

[0020] Example 2, as Figure 4 and Figure 5 As shown, the top of the wax storage tank 201 is connected to an anti-solidification component 3. The anti-solidification component 3 includes a top cover 301. The top of the top cover 301 is connected to a stirring motor 302. A feed inlet 303 is connected to the top of one side of the top cover 301. A heating wire 305 is installed inside the wax storage tank 201. A stirring rod 304 is connected to the output end of the stirring motor 302.

[0021] The effect achieved in Example 2 is that after the wax is poured into the wax storage tank 201 through the feed port 303, the stirring motor 302 can be turned on to drive the stirring rod 304 to rotate, thereby stirring the wax inside the wax storage tank 201. Under the electric heating effect of the heating wire 305, the wax solidification is effectively prevented, ensuring the stability during spraying.

[0022] Working principle: When waxing the gasket body 213, the required option can be selected on the PLC controller 214 according to the actual thickness required. Then, the wax storage tank 201 will automatically flow into the receiving cylinder 206. At the same time, under the action of the one-way screw 204, the nozzle 211 will move in the opposite direction, thereby achieving the effect of uniformly spraying wax on multiple gasket bodies 213 at the same time. After the wax is sprayed, the receiving cylinder 206 will automatically move to one side to wait for the next use. Thus, by controlling the amount of wax, the thickness of the wax coating on the surface of the pressure-sensitive gasket can be controlled, while improving the processing efficiency of the gasket body 213. After the wax is poured into the wax storage tank 201, the stirring motor 302 can be turned on to drive the stirring rod 304 to rotate, thereby stirring the wax inside the wax storage tank 201. With the heating effect of the heating wire 305, the wax solidification is prevented, ensuring the stability during spraying.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
