Description

Technical Field

[0001] This utility model relates to the technical field of wet wipe production equipment, specifically to a wet wipe production equipment. Background Technology

[0002] In the production process of wet wipes, the raw material cloth rolls need to be continuously unrolled through the cloth unwinding device. After unwinding, the cloth rolls are processed by the folding mechanism, liquid adding equipment, stacking device, and packaging equipment at the end, thus realizing the entire production process of wet wipes.

[0003] In actual production, in order to ensure stable production, the raw material roll needs to be unwound under constant tension in the unwinding device. Therefore, based on actual production experience, the applicant proposed "a tension-stabilized unwinding frame for wet wipes", which is recorded in Chinese Utility Model Patent CN222373974U. It includes a frame, unwinding shaft, splicing device, guide roller, buffer device and cloth support device to achieve tension-stabilized unwinding. In actual production, it was found that setting the cloth support device below the raw material roll resulted in high energy consumption of the equipment during the process, which was not conducive to saving production costs.

[0004] Therefore, the applicant further optimized the previously disclosed equipment by setting the bottom support device as a pressing device on the raw material cloth roll, which can achieve pressure control of the raw material cloth roll with less power output, making it more energy-efficient and helping to save costs.

In this embodiment, the stacking device 4 is an existing mature device, and the specific structure and principle will not be described in detail.

[0027] The principle of this utility model is as follows: In this utility model, when the fabric feeding device 1 is in use, the raw material fabric roll 12 is installed on the unwinding shaft 1131. Under the power traction of the rear equipment (not shown in the figure), the raw material fabric roll 12 rotates and the fabric is fed out. After passing through the splicing device 13, the fabric is conveyed to the buffer device 14 through the guide roller 1121. In the fabric feeding device 1, the splicing device 13 cooperates with the photoelectric sensor 155. The photoelectric sensor 155 detects that the fabric on a roll is about to be unloaded and transmits the signal to the field PLC. The field PLC controls the splicing device 13 to automatically switch to full roll. During the process, the splicing device 13 is the existing type. The fabric feeding device 1 involved in this utility model has not made any improvements to this, so it will not be described in detail.

[0028] As the fabric passes through the guide roller 1121, the tension of the fabric can be adjusted by the up-and-down movement of the moving roller 142 in the buffer device 14. The process involves the detection of fabric tension and the control of the hydraulic mechanism 141 by the field PLC based on the detection signal. This process is a mature existing technology and will not be described in detail.

[0029] In the fabric feeding device 1 disclosed in this utility model, the structure has been optimized compared with the fabric feeding device previously disclosed by the applicant, such as... Figure 6 As shown in the prior art documents, the pressure of the fabric roll is adjusted by a fabric support device located below the fabric roll. In the fabric feeding device 1 of this utility model, the pressure is adjusted by a fabric pressing device 15 located above the fabric roll.

[0030] like Figure 6 As shown, for ease of comparison, the position of the fulcrum of the cylinder 152 and the angle of the cylinder 152 in the present invention's pressing device 15 are set to be the same as those in the previously disclosed fabric supporting device. Thus, it can be clearly seen that the present invention has… In the prior art solutions, there are... If we assume the forces acting on the roll of cloth are uniform, i.e., F2 = F4, then we have It can be seen that F1 < F3, that is, under the condition that the cloth roll is subjected to the same force, the force output by the cylinder 152 in this utility model is less than that in the prior art.

[0031] Assuming the aforementioned angle remains constant, let the force acting on the fabric roll undergo the same change simultaneously, that is... Therefore, in this utility model, there are In the prior art solutions, there are Therefore, , , that is Then there is , Therefore, it can be seen that, under the same force change, the force output by this utility model is significantly less than that of the prior art.

[0032] It is easy to see that in this utility model, the power output of cylinder 152 is significantly better than the applicant's prior technical solution, which has a positive effect on reducing energy consumption.

[0033] This utility model also includes a folding mechanism 2, a liquid adding device 3, and a stacking device 4. In use, the product raw materials are conveyed to the folding mechanism 2. The folding mechanism 2 turns the conveying direction of the material by 90° through the turning mechanism 21. The tension is adjusted in real time by the tension detection device 22, and the fabric is corrected in real time by the correction device 23 to ensure that the material is neatly conveyed to the folding mechanism 24. After the material is folded, it is conveyed to the liquid adding device 3. The liquid adding device 3 accurately controls the amount of raw material liquid added to the folded material. After the raw material liquid is added, the material is conveyed to the stacking device 4. The stacking device 4 cuts the material to the set size, stacks it, detects and rejects unqualified products in real time, and conveys qualified products to the packaging machine and other downstream equipment. In this utility model embodiment, the folding mechanism 2, the liquid adding device 3, and the stacking device 4 are existing mature equipment. Therefore, the specific structural principles will not be described in detail.
