Description

Technical Field

[0001] This utility model relates to the technical field of wet wipe production equipment, specifically a device for preventing paper clamping during wet wipe sealing production. Background Technology

[0002] The production process of wet wipes typically includes: folding, cutting, wetting, and packaging. The packaging stage involves placing one or more wet wipes into a thin film insert and sealing it with heat to ensure hygiene, moisture retention, and leak-proofness. However, during this heat-sealing process, the bottom layer of wet wipes tends to sag due to gravity. These sagded wipes become trapped inside the inner seal of the package. During heat sealing, the presence of moisture and the wet wipes obstructing the sides of the inner seal hinder the heat-sealing operation, resulting in defective products. Therefore, we propose an anti-paper-clamping device for the inner sealing production of wet wipes. Utility Model Content

[0003] The purpose of this utility model is to provide a device for preventing paper clamping during the production of wet wipes, which solves the problems mentioned in the background art.

[0011] By employing the above technical solution, this utility model provides a device for preventing paper clamping during the production of wet wipes with a center seal, which has at least the following beneficial effects: (1) The present invention uses two rollers that fit together to detect the thickness of the middle seal in real time through the detection mechanism. This allows for timely detection and identification when the thickness of the middle seal changes, thus enabling rapid detection of the paper clamping state. At the same time, the roller structure facilitates the movement of the middle seal of the packaging bag.

[0012] (2) The present invention can automatically reset the detection rod by means of the reset spring structure, so that the two rollers can keep in contact and realize the detection operation of the center seal.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1 A device for preventing paper pinching during the production of wet wipes, such as... Figures 1-4 As shown, it includes a frame 1; the frame 1 is equipped with a detection mechanism 2, which can automatically perform thickness detection on the packaging of wet wipes. When paper jam occurs and the thickness increases, the equipment will automatically stop running and sound an alarm to remind the staff to handle the situation.

[0017] Specifically, the testing mechanism 2 includes a testing frame 21, which is fixedly connected to the bottom of the frame 1. A testing rod 22 is slidably connected to the testing frame 21, and a roller 23 is rotatably connected to the end of the testing rod 22. The testing frame 21 can support the testing rod 22, allowing the testing rod 22 to slide inside the testing frame 21 to test the packaging status of the wet wipes. At the same time, the roller 23 can clamp the inner seal of the packaging, thereby facilitating the detection of the paper clamping status.

[0018] Based on this, a return spring 24 is fixedly connected inside the detection frame 21. One end of the return spring 24 abuts against the detection rod 22. The detection rod 22 has an "L"-shaped structure. The detection frame 21 has guide grooves 25 that correspond to the structure of the detection rod 22. The return spring 24 can push the detection rod 22 with its own elasticity, so that the rollers 23 on both sides can squeeze each other. A guide rod 26 is fixedly connected to the detection rod 22. Several sets of guide grooves 25 are provided. The number of guide grooves 25 is the same as the number of guide rods 26 and detection rods 22. The guide rod 26 can guide the movement of the detection rod 22 and prevent the detection rod 22 from deviating during the movement. The detection rod 22 and the guide rod 26 are slidably connected inside the guide grooves 25, so that the detection rod 22 can only slide and adjust along the direction of the guide grooves 25.

[0019] In addition, a distance sensor 27 is fixedly connected inside the detection frame 21. The distance sensor 27 corresponds to the position of the detection rod 22. A positioning groove 28 is provided on the frame 1. The positioning groove 28 corresponds to the position of the roller 23. The distance sensor 27 can detect the position of the detection rod 22 in real time. When paper jam occurs, the roller 23 will drive the detection rod 22 to move, and the distance sensor 27 can obtain the displacement of the detection rod 22 in time.

[0020] Example 2 like Figures 1-2 As shown, based on Embodiment 1, the frame 1 is provided with a sealing mechanism 3, which can seal the inner seal of the wet wipe packaging after testing.

[0021] In this embodiment, the sealing mechanism 3 includes two hot-melt rods 31, which are connected to the bottom of the frame 1. The hot-melt rods 31 are connected to the end away from the detection frame 21. An alarm 32 is fixedly connected to the side of the frame 1. The ranging sensor 27 is electrically connected to the hot-melt rods 31 and the alarm 32 respectively. The hot-melt rod 31 can perform hot-melt sealing on the wet wipe packaging after the test is completed. The alarm 32 can warn the staff. The electrically connected detection structure can quickly disconnect the hot-melt rod 31 when a paper jam is detected, so as to prevent the hot-melt rod 31 from sealing the diameter to the inside of the packaging.

[0022] It is worth noting that a conveyor belt device 33 is connected to the top of the frame 1. The conveyor belt device 33 is symmetrically arranged on both sides of the positioning groove 28. The outer shell 34 is fixedly connected to the top of the frame 1. The conveyor belt device 33 can transport the packaging and wet wipes from one end of the frame 1 to the other end, which facilitates real-time detection of the moving packaging.

[0023] In use, the anti-pinch paper device for producing wet wipes with a center seal involves the packaging moving from one end of the frame 1 to the other under the conveyor belt 33. Simultaneously, the center seal of the packaging moves along the positioning groove 28, passing between two rollers 23. The two rollers 23 continuously compress the center seal of the packaging belt. The continuously moving packaging moves from the position of the detection rod 22 and the rollers 23 to the hot-melt rod 31, which continuously operates and performs a hot-melt sealing operation on the center seal of the packaging.

[0024] When paper gets stuck on the inner side of the packaging, the thickness of the inner side of the packaging increases accordingly. When the package with paper stuck moves to roller 23, it opens roller 23, and the detection rod 22 moves away from roller 23. After detecting the movement of the detection rod 22, the distance sensor 27 stops the conveyor belt device 33 from conveying the package and wet wipes, shuts off the hot melt rod 31, and sounds an alarm through the alarm 32 to remind the staff to handle the package with paper stuck.
