Description

Technical Field

[0001] The invention relates to a raw material feeding device and production equipment comprising the same. Background Art

[0002] Existing production equipment for packaging non-woven hygiene products such as dry wipes and wet wipes is not yet fully automated and capable of precise production precision control. For example, the raw material feeding system, which feeds the non-woven fabric in a rotating manner, can easily lead to excessively slow or excessive feeding due to poor rotational speed control, making precise feed speed control difficult. The subsequent cutting, injection, and packaging processes all rely on the feed speed as a reference for execution, making feed speed controllability crucial for the production of these products.

[0003] During normal loading, the material feed rate is uniform, and the material is generally in a taut state. However, at the beginning of loading, the material is subjected to a sudden tensile force, which can cause it to unwind quickly, resulting in a lack of tension and slack. This can lead to loosening or angular deviation, affecting the normal operation of subsequent processes. Furthermore, when loading stops, the material continues to rotate and unwind due to inertia, which can further cause the material to loosen.

[0004] Therefore, it is urgent to find a method that can keep the raw material taut all the time. Summary of the Invention

DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0039] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0040] In view of the importance of tensioning the raw materials during the feeding of roll-shaped raw materials in the current production of non-woven sanitary products for the continuous and stable production progress, this embodiment provides a raw material feeding device that can effectively control the tension of the raw materials. Figure 1-4 A raw material feeding device and a production equipment including the same protected by the present invention are described in detail.

[0041] Example 1

[0042] Reference Figure 1 As shown, this embodiment provides a raw material feeding device, which includes: a first bracket 10, a feed control mechanism 20, and at least one raw material storage mechanism 30, wherein the feed control mechanism 30 and the raw material storage mechanism 30 are both disposed on the first bracket 10. It should be noted that the raw material feeding device in this embodiment is applied to production equipment for sanitary products such as wet wipes and dry wipes that use roll-shaped materials as raw materials, and is used for storing and feeding raw materials.

[0043] like Figure 1 、 2 As shown, specifically, the feed control mechanism 20 includes a second bracket 21, an anti-slip component 22, and a positioning component 23. The second bracket 21 is movably mounted on the first bracket 10. At least one anti-slip component 22 is mounted on the second bracket 21 and movably engages with the raw material 40 to achieve relative motion between the anti-slip component 22 and the raw material and generate a certain friction force. The positioning component 23 is connected to the second bracket 21 to control the position of the second bracket 21 on the first bracket 10. As a preferred embodiment, the second bracket 21 is vertically and movably mounted on the first bracket 10.

[0044] Further Figure 1 As shown, the second bracket 21 includes a second bracket body 211 and an adjustment shaft 212 connected to the second bracket body 211 at an angle. The anti-slip assembly 22 includes a first fixing member 221, a flexible member 222, and a counterweight 223. One end of the flexible member 222 is connected to the first fixing member 221, and the other end is connected to the counterweight 223. The first fixing member 221 is movably mounted on the adjustment shaft 212. In this embodiment, the adjustment shaft 212 is higher than the raw material 40. When the first fixing member 221 is movably mounted on the adjustment shaft 212, the counterweight 223 has a certain weight. Under the action of its own weight, it acts on the flexible member 222 and causes it to droop, so that the flexible member 222 is at least partially suspended from the surface of the raw material 40 and exerts a certain pressure on the raw material 40.

[0045] With this structure, when the material is being fed normally, the friction generated by the anti-slip assembly 22 and the material increases its rotational speed, thereby ensuring that the material remains taut during feeding. If the material is suddenly started after stopping, the friction generated by the anti-slip assembly 22 and the material prevents excessive acceleration, which could lead to excessive material discharge and other problems such as loosening or angular deviation. If the material is suddenly stopped during feeding, the material's inertia and the friction generated by the anti-slip assembly 22 quickly stop it, preventing it from loosening. Therefore, the anti-slip assembly 22 ensures that the material feeding portion remains taut.

[0046] Preferably, the adjusting shaft 212 is a rod-shaped structure, the first fixing part 221 is a ring-shaped structure, and the first fixing part 221 is movably mounted on the adjusting shaft 212. By adjusting the specific position of the first fixing part 221 on the adjusting shaft 212, the anti-slip component 22 can be matched with raw materials 40 of different sizes (width sizes) to improve the versatility of the raw material feeding device.

[0047] like Figure 3 As shown, the positioning assembly 23 includes a controller (not shown), a servo motor 231 connected to the controller, and a synchronous belt 232 connected to the servo motor 231, and the synchronous belt 232 is connected to the second bracket 21. Specifically, the positioning assembly 23 also includes a connector 233, one end of the connector 233 is connected to the second bracket 21, and the other end is connected to the synchronous belt 232; preferably, the connector is an L-shaped structure, and the vertical portion is connected to the lower end of the second bracket 21, and the horizontal portion is connected to the synchronous belt 232. It should be noted that this embodiment does not limit the specific type of controller, as long as it can realize the control of the position, speed, etc. of the servo motor 231 in this field, such as a servo motor controller.

[0048] More preferably, referring to Figure 2-3 As shown, the second bracket body 211 is vertically connected to the first bracket 10, and the second bracket body 211 is movably arranged compared to the first bracket 10, that is, under the control of the above-mentioned controller, the servo motor 231 controls the movement of the synchronous belt 232, and the synchronous belt 232 drives the second bracket body 211 to move compared to the first bracket 10 through the connecting member 233, thereby realizing the relative action state of the flexible member 222 and the raw material 40 in the anti-slip component 22.

[0049] like Figure 3 As shown, in order to achieve the movement of the second bracket body 211 compared to the first bracket 10, in this embodiment, the first bracket 10 includes a slide rail 11 that cooperates with the second bracket body 211. Of course, in another optional embodiment, the first bracket 10 includes a slide groove (not shown) that cooperates with the second bracket body 211.

[0050] Further references Figure 1 、 2 As shown, the raw material storage mechanism 30 is provided on the first bracket 10 , and includes a support rod 31 , a sliding mechanism 32 sleeved on the support rod 31 , and the raw material 40 is rotatably sleeved on the sliding mechanism 32 .

[0051] Specifically, the slip mechanism 32 includes at least two bearings 321 mounted on the support rod 31 and at least two stoppers 322 detachably mounted on the bearings 321. When the material storage mechanism 30 stores at least one material 40, the material 40 is mounted on any one of the bearings 321. Each anti-slip assembly 22 engages with a corresponding material 40, and at least a portion of the flexible member 222 is movably mounted on the surface of the material 40 along its circumferential surface.

[0052] At least two stoppers 322 are provided on either side of the raw material 40 and engage tightly with the raw material 40. Preferably, the stoppers are clamping shafts. Typically, the raw material loading device of this embodiment is used in multi-row production equipment, so at least two rolls of raw material are stored on the sliding mechanism 32. To improve compactness, a small clamping shaft is used between any two adjacent rolls of raw material 40, while a large clamping shaft is used on the outer sides of the raw material 40 on both sides to improve the reliability of the limit.

[0053] In order to achieve contact between the anti-slip component 22 and the raw material 40, in a preferred embodiment, the support rod 31 is arranged parallel to the adjustment shaft 212, and the adjustment shaft 212 is located above the support rod 31. At this time, the radial direction of the raw material is parallel to the running direction of the synchronous belt.

[0054] The support rod 31 and the adjustment shaft 212 may be located in the same vertical plane or in different vertical planes. Those skilled in the art should know that the sliding friction force F = μF n , where F is the sliding friction force, μ is the dynamic friction coefficient, and F n is pressure. In this embodiment, the magnitude of the sliding friction force F depends on the vertical pressure exerted by the flexible member 222 on the raw material 40. This pressure is related to the pulling force of the counterweight 223 and the tension of the flexible member 222 caused by the angle between the flexible member 222 and the raw material 40. The angle between the flexible member 222 and the raw material 40 is related to the relative position of the support rod 31 and the adjustment shaft 212, as well as the raw material diameter (remaining amount of raw material). Therefore, in this embodiment, by configuring the counterweight 223 with corresponding weights and the relative position of the support rod 31 and the adjustment shaft 212 for different raw material diameters, the sliding friction between the flexible member 222 and the surface of the raw material 40 can be adjusted, thereby improving the rotational stability during the raw material feeding process, thereby ensuring that the raw material feeding part is always in a tensioned state.

[0055] In this embodiment, since the support rod 31 is fixed in position, the feed control mechanism 20 is provided to adjust the position of the adjustment shaft 212. Further preferably, the support rod 31 can also be adjusted in position by providing a servo motor and a synchronous belt to further improve production accuracy.

[0056] The present embodiment does not limit the specific structure of the first bracket 10 , and only requires that it can provide corresponding accommodation space for the feed control mechanism 20 and the raw material storage mechanism 30 without causing installation interference.

[0057] For example, Figure 1 As shown, the first bracket 10 also includes a base 12 and a support mechanism 13 vertically connected to the base 12. The support mechanism 13 includes a frame structure 14 disposed at its upper end. The base 12 and the support mechanism 13 form at least one receiving space for a raw material storage mechanism 30 and raw materials 40. The raw material storage mechanism 30 is connected to the side of the frame structure 14, and a timing belt 232 is disposed within the frame structure 14. The second bracket body 211 is connected to the upper portion of the frame structure 14.

[0058] In this embodiment, the support mechanism 13 is vertically connected to the middle of the base 12, thereby forming two relatively arranged raw material storage mechanisms 30 and a storage space for the raw material 40. Therefore, the second bracket body 211 and the anti-slip component 22 respectively include two relatively arranged sets to improve production output and the overall stability of the device.

[0059] This embodiment arranges an anti-skid component on the raw material feeding device to increase the friction force exerted on the rolled raw material during the rotating feeding process, so as to achieve the purpose of keeping the raw material feeding part in tension at all times. Furthermore, by setting a positioning component, the position of the raw material on the anti-skid component on the feeding device can be adjusted according to the remaining amount of raw material, thereby achieving the adjustment of the pressure between the anti-skid component and the raw material, and achieving the adjustment of the friction force between the anti-skid component and the raw material to further keep the raw material feeding part in tension at all times.

[0060] Example 2

[0061] like Figure 4 As shown, this embodiment provides a production device 200 for producing sanitary products such as wet wipes and dry wipes.

[0062] When the production equipment 200 is used to produce wet wipes, the production equipment 200 includes the raw material loading device 100 as described in Example 1, a steering device 300 provided at the output end of the raw material loading device 100, a cutting and folding device 400 provided at the output end of the steering device 300, a liquid adding device 500 provided at the output end of the cutting and folding device 400, an outer packaging material storage device 600 provided at the input end of the liquid adding device 500, and a packaging forming device 700 provided at the output end of the liquid adding device 500.

[0063] When the production equipment 200 is used to produce dry wipes, the production equipment 200 does not include the liquid adding device 500 .

[0064] The aforementioned steering device 300, folding device 400, liquid adding device 500, outer packaging material storage device 600, and packaging forming device 700 can be commonly used devices in the art. The specific technical features and corresponding technical effects of the raw material loading device 100 in this embodiment are described in detail in Example 1 and are not further elaborated in this embodiment.

[0065] All of the above optional technical solutions can be combined in any way to form optional embodiments of the present invention, that is, any multiple embodiments can be combined to meet the needs of different application scenarios. They are all within the scope of protection of this application and will not be described in detail here.

[0066] It should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
