Description

Technical Field

[0001] This invention relates to the field of disposable hygiene product manufacturing equipment, particularly to the fields of sanitary napkins, diapers, pull-up pants, and more specifically to an elastic thread breaking material deceleration clamping braking system and its manufacturing equipment for disposable hygiene products. Background Technology

[0002] Elastic thread materials are widely used in disposable hygiene products, such as disposable diapers. These diapers consist of an outer covering layer and an absorbent core within the outer covering layer. The outer covering layer is an elastic composite structure, typically composed of an outer sheet, an inner sheet, and elastic thread material positioned between the outer and inner sheets. Common elastic thread materials can be natural rubber strips (filaments) or synthetic filaments (root-like) elastic spandex filaments, etc. Manufacturing equipment for disposable hygiene products requires a series of process devices for unwinding, conveying, and cutting the elastic thread material. However, due to its elasticity, the elastic thread material exhibits a certain tension during operation. When the elastic thread material breaks, the tension dissipates, causing it to retract upstream and downstream from the break point. To prevent the retraction of the elastic thread material from requiring significant manual time for re-guiding the process path, a material-cutting clamping braking device is installed at an appropriate location in the elastic thread's flow path to stop its movement.

[0003] In the existing elastic wire process, a separate material breaking clamping and braking device is set at the preset material breaking position. However, no corresponding devices are set on the upstream and downstream sides. During the production process, the inventors discovered that when the elastic wire material has a higher stretch ratio or is thinner, if the elastic wire retraction speed is greater than the clamping and braking speed of the material breaking clamping and braking device after the material breaks, the material breaking clamping and braking device will be unable to brake the elastic wire, thus rendering the clamping and braking device ineffective. Summary of the Invention

[0004] This invention provides an elastic thread breakage deceleration clamping braking system and its manufacturing equipment for disposable sanitary products, to solve the technical problem that existing breakage clamping braking devices cannot brake the elastic thread when the elastic thread retraction speed is greater than the clamping braking speed of the breakage clamping braking device after the elastic thread material breaks.

[0005] The technical solution provided by this invention is as follows:

[0006] One object of the present invention is to provide an elastic wire breakage deceleration clamping and braking system, the system comprising: a clamping and braking device and a deceleration device arranged sequentially along the flow direction of the elastic wire conveying; the clamping and braking device is preset on the upstream side of the elastic wire breakage point;

[0007] The deceleration device includes a primary decelerator and a secondary decelerator. Along the flow direction of the elastic conveyor, the primary decelerator is located downstream of the secondary decelerator; the elastic conveyor is routed from the secondary decelerator to the primary decelerator.

[0008] When the elastic wire is being conveyed normally, the elastic wire is conveyed downstream along the flow direction of the elastic wire conveying under tension, through the clamping and braking device and the deceleration device.

[0009] When the elastic line breaks at the break point, the elastic line upstream of the break point retracts upstream due to the loss of tension until it is wound and slowed down by the secondary reducer or the primary reducer; the clamping and braking device stops the movement of the elastic line after it has been slowed down, so that the elastic line no longer retracts upstream.

[0010] In a preferred embodiment, the distance between the primary speed reducer and the secondary speed reducer in the flow direction should be less than 200 mm.

[0011] In a preferred embodiment, the system further includes an upstream guide roller and a downstream guide roller arranged along the flow direction of the elastic conveyor.

[0012] The upstream guide roller is arranged on the upstream side of the clamping and braking device, and the downstream guide roller is arranged on the downstream side of the deceleration device;

[0013] The elastic line is conveyed downstream along the flow direction of the elastic line, passing sequentially through the upstream guide roller, the clamping and braking device, the deceleration device, and the downstream guide roller.

[0014] In a preferred embodiment, the clamping and braking device includes: a retaining seat and a clamping member; the retaining seat has a first groove in the flow direction along the elastic line, the first groove having an inlet and an outlet in the flow direction along the elastic line; wherein, in the thickness direction perpendicular to the flow direction, the size of the outlet is larger than the size of the inlet.

[0015] The elastic line enters the first chute through the inlet and extends out of the first chute through the outlet, and is conveyed downstream along the flow direction of the elastic line.

[0016] The clamping member is configured to reciprocate within the first chute along the flow direction of the elastic line; when the elastic line breaks at the break point, the clamping member moves towards the inlet direction of the first chute under the action of gravity, stopping the elastic line from retracting upstream in the retraction direction.

[0017] The first chute includes at least a first inclined surface disposed along the flow direction of the elastic conveyor, the first inclined surface causing the first chute to form the inlet and the outlet along the flow direction of the elastic conveyor;

[0018] The clamping member includes at least a second inclined surface that matches the first inclined surface, and the elastic line is disposed between the first inclined surface and the second inclined surface;

[0019] When the elastic line is being conveyed normally, under the tension of the elastic line, the clamping member is driven to move towards the outlet direction of the first chute, so that the second inclined surface moves away from or contacts the first inclined surface.

[0020] When the elastic line breaks at the break point, the clamping member moves towards the entrance of the first chute under the action of gravity, causing the second inclined surface to contact the first inclined surface, thereby stopping the movement of the elastic line disposed between the first inclined surface and the second inclined surface, so that the elastic line no longer retracts upstream.

[0021] In a preferred embodiment, the retainer includes a second chute disposed along the flow direction of the elastic conveyor; the length of the second chute is smaller than the length of the first chute along the flow direction of the elastic conveyor.

[0022] The clamping member includes a guide portion disposed along the flow direction of the elastic line conveying, the guide portion being embedded in the second slide groove;

[0023] When the clamping member reciprocates along the flow direction of the elastic line within the first slide groove, the guide portion reciprocates along the second slide groove to limit the range of motion of the clamping member.

[0024] In a preferred embodiment, the clamping braking device further includes a fixing member disposed at the outlet of the first slide groove, which limits the reciprocating up and down movement of the clamping member along the flow direction of the elastic line conveying in the first slide groove, so as to prevent the clamping member from sliding out of the first slide groove.

[0025] In a preferred embodiment,

[0026] The inner surface of the first chute is a first conical surface, which causes the first chute to form the inlet and the outlet along the flow direction of the elastic line transport.

[0027] The clamping member includes a clamping body having a regular second conical surface that matches the first conical surface, and the elastic line is disposed between the first conical surface and the second conical surface;

[0028] The clamping body is configured to reciprocate within the first chute along the flow direction of the elastic line;

[0029] When the elastic line is being conveyed normally, under the tension of the elastic line, the clamping body is driven to move towards the outlet direction of the first chute, so that the second conical surface moves away from or contacts the first conical surface.

[0030] When the elastic line breaks at the break point, the clamping body moves towards the entrance of the first chute under the action of gravity, causing the second conical surface to contact the first conical surface, thereby stopping the movement of the elastic line disposed between the first conical surface and the second conical surface, so that the elastic line no longer retracts upstream.

[0031] In a preferred embodiment, the clamping braking device further includes a fixing member disposed at the outlet of the first slide groove, which limits the reciprocating movement of the clamping body in the first slide groove along the flow direction of the elastic line conveying, so as to prevent the clamping body from sliding out of the first slide groove.

[0032] In a preferred embodiment, the first-stage reducer is a guide wheel structure, and the second-stage reducer is a guide wheel structure;

[0033] In the width direction, the first-stage reducer has a first guide groove, and the second-stage reducer has a second guide groove;

[0034] The elastic wire is embedded in the second guide groove of the secondary reducer and winds around the primary reducer through the secondary reducer. The elastic wire is embedded in the first guide groove of the primary reducer.

[0035] Wherein, the side on which the elastic wire is embedded in the second guide groove of the secondary reducer is opposite to the side on which the elastic wire is embedded in the first guide groove of the primary reducer;

[0036] When the elastic wire breaks at the break point, the elastic wire located upstream of the break point retracts upstream due to the loss of tension and is slowed down by the secondary deceleration component.

[0037] In a preferred embodiment, the first-stage reducer is a guide wire structure, and the second-stage reducer is a guide wheel structure;

[0038] Along the flow direction of the elastic conveyor, the first-stage reducer has an opening for the elastic conveyor to pass through; in the width direction, the second-stage reducer has a second guide groove.

[0039] The elastic wire is embedded in the second guide groove of the secondary reducer and winds around one side of the secondary reducer toward the primary reducer, wherein the elastic wire passes through the opening of the primary reducer;

[0040] When the elastic wire breaks at the break point, the elastic wire located upstream of the break point retracts upstream due to the loss of tension and is slowed down by the secondary reducer or the primary reducer.

[0041] In a preferred embodiment, the first-stage reducer is a rotatable guide rod structure, and the second-stage reducer is a rotatable guide rod structure.

[0042] Along the flow direction of the elastic conveyor, the elastic conveyor wraps around the guide bar of the secondary reducer, and then wraps around the guide bar of the primary reducer via the secondary reducer.

[0043] Wherein, the elastic line is wound around one side of the guide rod of the secondary reducer, which is opposite to the side of the elastic line wound around the guide rod of the primary reducer;

[0044] When the elastic wire breaks at the break point, the elastic wire located upstream of the break point retracts upstream due to the loss of tension and is slowed down by the secondary deceleration component.

[0045] Another object of the present invention is to provide a manufacturing apparatus for disposable hygiene products, including at least one set of elastic thread breaking deceleration clamping and braking system.

[0046] The above-described technical solution of the present invention has at least the following beneficial effects compared with the prior art:

[0047] This invention provides a deceleration and clamping braking system for broken elastic wire. A deceleration device is provided on the downstream side of the clamping and braking device to decelerate the elastic wire as it retracts upstream after breaking. This allows the clamping and braking device to easily clamp and brake the elastic wire at low speeds. Regardless of whether the elastic wire has a high stretch ratio or is very thin, the probability of clamping and braking can reach nearly 100%, enabling the clamping and braking device to play a greater role and significantly reducing the time spent stopping to pull the elastic wire.

[0048] This invention discloses a small-sized, electrically controlled, and mechanically-operated elastic wire deceleration and braking system for cutting off materials. It is applicable to manufacturing equipment for disposable hygiene products. Furthermore, it can be installed at any desired location, unconstrained by process flow or space limitations, significantly reducing the time required to catch the elastic wire and thus improving equipment production efficiency.

[0078] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0081] Example 1.

[0082] Combination Figures 1 to 7According to an embodiment of the present invention, a flexible wire breakage deceleration clamping braking system is provided. The flexible wire P is conveyed forward along the flow direction a of the flexible wire conveying process. The location where material breakage is likely to occur during the conveying of the flexible wire P is the flexible wire breakage point P'. In this invention, the flow direction a of the flexible wire P is vertical. Figure 1 The process direction 'a' shown is from bottom to top. Here, 'vertical' refers to the direction relative to traditional horizontal conveying; it does not mean that the process direction 'a' in flexible line conveying is perfectly straight.

[0083] It is worth noting that the breakage point P' of the elastic wire here refers to the point where the elastic wire P is prone to breakage in the manufacturing equipment for disposable hygiene products. This can occur at multiple stations in the process. To illustrate the elastic wire breakage deceleration and clamping braking system of this invention, the breakage point P' is set as... Figure 1 The location is described (as in the accompanying diagram below).

[0084] like Figure 1 As shown in the embodiment of the present invention, a flexible material breakage deceleration clamping and braking system includes: a clamping and braking device 2 and a deceleration device 3 arranged sequentially along the flow direction a of the flexible material conveying P. The clamping and braking device 2 is pre-positioned upstream of the flexible material breakage point P', and the deceleration device 3 is located upstream of the flexible material breakage point P'.

[0085] Furthermore, upstream guide roller 1 and downstream guide roller 1' are arranged along the flow direction a of the elastic line P. Upstream guide roller 1 is arranged upstream of clamping and braking device 2, and downstream guide roller 1' is arranged downstream of deceleration device 3.

[0086] The elastic line P is conveyed along the flow direction a of the elastic line, and is sequentially conveyed to the downstream side via the upstream guide roller 1, the clamping and braking device 2, the deceleration device 3 and the downstream guide roller 1'.

[0087] Specifically, the elastic thread P is guided by the upstream guide roller 1, so that it enters the clamping and braking device 2 with a certain wrap angle. The wrap angle improves the accuracy of the elastic thread P's conveying position and provides the prerequisite for the clamping and braking of the clamping and braking device 2. Afterwards, the elastic thread P is conveyed downstream through the clamping and braking device 2, the deceleration device 3, and the downstream guide roller 1'. The downstream guide roller 1' guides the elastic thread P and continues to convey it into the subsequent process.

[0088] Combination Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 According to an embodiment of the present invention, the clamping braking device 2 includes: a retaining seat 21, a clamping member 22, and a fixing member 23.

[0089] The retainer 21 has a first chute 211 in the flow direction a along the elastic line, the first chute 211 having an inlet I and an outlet O along the flow direction a; wherein, along the thickness direction d perpendicular to the flow direction a, the size of the outlet O is larger than the size of the inlet I.

[0090] The elastic line P enters the first chute 211 through the inlet I and extends out of the first chute 211 through the outlet O, and is conveyed downstream along the flow direction a of the elastic line.

[0091] The clamping member 22 is configured to reciprocate along the flow direction a of the elastic line conveying in the first chute 211; when the elastic line P breaks at the break point of the elastic line, the clamping member 22 moves towards the inlet I of the first chute 211 under the action of gravity, and stops the elastic line P from retracting upstream in the retraction direction.

[0092] Specifically, the retaining seat 21 has a first chute 211 formed along the flow direction a of the elastic conveying line. The first chute 211 includes at least a first inclined surface 2111 formed along the flow direction a of the elastic conveying line, which forms an inlet I and an outlet O in the first chute 211 along the flow direction of the elastic conveying line. In the thickness direction d perpendicular to the flow direction, the size of the outlet O is larger than the size of the inlet I, that is, the first chute 211 gradually widens from the inlet I to the outlet O in the thickness direction d. The thickness direction d is a direction perpendicular to both the flow direction a and the width direction b, and the flow direction a, width direction b, and thickness direction d are all perpendicular to each other.

[0093] The clamping member 22 is configured to reciprocate within the first groove 211 along the flow direction a of the elastic line. The clamping member 22 includes at least a second inclined surface 221 that matches the first inclined surface 2111, and the elastic line P is disposed between the first inclined surface 2111 and the second inclined surface 221.

[0094] When the elastic line P is being conveyed normally, under the tension of the elastic line P, the clamping member 22 is driven to move towards the outlet O of the first chute 211, so that the second inclined surface 221 moves away from or contacts the first inclined surface 2111.

[0095] That is, during operation, the tension of the elastic line P is not constant in reality (it is constant in the ideal state); sometimes the tension is higher, and sometimes it is lower. When the clamping member 22 is under the action of a larger tension of the elastic line P, the clamping member 22 moves towards the outlet O of the first chute 211, causing the second inclined surface 221 to move away from the first inclined surface 2111. At this time, a gap is formed between the second inclined surface 221 and the first inclined surface 2111 (this gap varies depending on the tension of the elastic line P), and the elastic line P is conveyed downstream through the gap between the second inclined surface 221 and the first inclined surface 2111.

[0096] In another scenario, when the elastic line P is under relatively low tension, and the clamping member 22 moves toward the outlet O of the first slide groove 211, the second inclined surface 221 of the clamping member 22 does not completely separate from the first inclined surface 2111 of the retaining seat 21 due to the relatively low tension generated by the elastic line P. At this time, the second inclined surface 221 of the clamping member 22 and the first inclined surface 2111 of the retaining seat 21 come into contact. This contact is merely the second inclined surface 221 touching the first inclined surface 2111 through the elastic line P, and there is no clamping state.

[0097] Therefore, during the operation of the elastic line P, due to the different tension of the elastic line P, the clamping member 22 reciprocates in the first slide groove 211 along the flow direction a of the elastic line, so that the elastic line P will always switch back and forth between the first inclined surface 2111 and the second inclined surface 221 in a state of contact or separation.

[0098] When the elastic line P breaks at the break point P', the clamping member 22 moves towards the inlet I of the first chute 211 under the action of gravity, so that the second inclined surface 221 contacts the first inclined surface 2111, thereby stopping the movement of the elastic line P arranged between the first inclined surface 2111 and the second inclined surface 221, so that the elastic line P no longer retracts upstream.

[0099] When the elastic wire P breaks at the break point P', the tension of the elastic wire P disappears, and under the action of gravity, the clamping member 22 moves towards the inlet I of the first chute 211. The second inclined surface 221 of the clamping member 22 contacts the first inclined surface 2111 of the retaining seat 21 (in the opposite direction to the movement of the clamping member 22 towards the outlet O of the first chute 211 under the tension of the elastic wire P during normal conveying). The elastic wire P is clamped and braked by the second inclined surface 221 of the clamping member 22 and the first inclined surface 2111 of the retaining seat 21. Therefore, the "contact" here is different from the "contact" expressed during the normal conveying of the elastic wire P.

[0100] like Figure 3 and Figure 4 As shown, according to an embodiment of the present invention, the retainer 21 includes a second groove 212 disposed along the flow direction a of the elastic conveying line. The length of the second groove 212 along the flow direction a of the elastic conveying line is smaller than the length of the first groove 211. The clamping member 22 includes a guide portion 222 disposed along the flow direction a of the elastic conveying line, the guide portion 222 being embedded within the second groove 212.

[0101] When the clamping member 22 reciprocates along the flow direction a of the elastic line within the first slide groove 211, the guide portion 222 reciprocates along the second slide groove 212 to limit the range of motion of the clamping member 22. Specifically, along the flow direction a of the elastic line, since the length of the second slide groove 212 is smaller than the length of the first slide groove 211, when the guide portion 222 moves to the bottom of the second slide groove 212, the clamping member 22 stops moving within the first slide groove 211, effectively limiting the movement of the clamping member 22 along the flow direction a of the elastic line.

[0102] like Figure 2 and Figure 5 As shown, the clamping and braking device 2 also includes a fixing member 23. The fixing member 23 is disposed at the outlet O of the first slide groove 211 and limits the up-and-down reciprocating movement of the clamping member 22 in the first slide groove 211 along the flow direction a of the elastic line, so as to prevent the clamping member 22 from sliding out of the first slide groove 211.

[0103] According to the present invention, in some embodiments, the first inclined surface 2111 and the second inclined surface 221 are made of various materials such as metal, nylon, aluminum alloy, or elastic material. This is because a deceleration device 3 (specific structure described below) is provided on the downstream side of the clamping and braking device 2. The deceleration device 3 decelerates the elastic wire P by winding it, thereby enabling the clamping and braking device 2 to easily clamp and brake the elastic wire P at low speed. Therefore, the material requirements for the first inclined surface 2111 and the second inclined surface 221 are naturally not as high.

[0104] When the elastic line P breaks at the break point P', the retraction speed of the elastic line P towards the upstream side is greater than the speed at which the clamping member 22 of the clamping and braking device 2 moves towards the inlet I of the first chute 211 under the action of gravity (that is, the clamping and braking speed of the first inclined surface 2111 and the second inclined surface 221). As a result, before the first inclined surface 2111 and the second inclined surface 221 can clamp the elastic line P, the elastic line P has already retracted to the upstream side of the clamping and braking device 2. Therefore, the clamping and braking device 2 cannot effectively clamp the elastic line P after the break, and the clamping and braking device 2 becomes futile.

[0105] In order to solve the problem that the clamping and braking device 2 cannot effectively clamp the elastic line P after the material breaks, the present invention arranges a deceleration device 3 along the flow direction a of the elastic line P. The deceleration device 3 is located downstream of the clamping and braking device 2 and upstream of the elastic line break point P'.

[0106] like Figure 1As shown, according to an embodiment of the present invention, the deceleration device 3 includes a primary decelerator 31 and a secondary decelerator 32, which are conveyed along the flow direction a of the elastic line P. The primary decelerator 31 is located downstream of the secondary decelerator 32. The elastic line P extends from one side of the secondary decelerator 32 to the primary decelerator 31.

[0107] When the elastic wire P is being conveyed normally, under tension, it is conveyed downstream along the flow direction a, passing through the clamping and braking device 2 and the deceleration device 3. Figure 1 and Figure 6 As shown.

[0108] When the elastic cord P breaks at the break point P', the elastic cord P on the side of the break point P' retracts upstream due to the loss of tension until it is wound and decelerated by the secondary reducer 32 or the first reducer 31. The clamping and braking device 2 stops the movement of the decelerated elastic cord P, so that the elastic cord P no longer retracts upstream. Figure 5 As shown.

[0109] In order to achieve a good speed reduction effect of the speed reduction device 3, the distance between the first-stage speed reducer 31 and the second-stage speed reducer 32 in the flow direction should be less than 200mm. This is because when the distance between the first-stage speed reducer 31 and the second-stage speed reducer 32 is greater than 200mm, it is difficult for the elastic line P to wrap around the second-stage speed reducer 32 and thus reduce speed.

[0110] In this embodiment, the first-stage reducer 31 is a guide wheel structure, and the second-stage reducer 32 is a guide wheel structure. For example... Figure 6 As shown, in the width direction b, the first-stage reducer 21 has a first guide groove 311, and the second-stage reducer has a second guide groove 321. In this invention, the width direction b refers to the direction perpendicular to the flow direction a.

[0111] The elastic wire P is embedded in the second guide groove 321 of the secondary reducer 32, and then winds around the primary reducer 31 through the secondary reducer 321. The elastic wire P is embedded in the first guide groove 311 of the primary reducer 31.

[0112] The elastic wire P is embedded in one side of the second guide groove 321 of the secondary reducer 32, which is opposite to the side of the elastic wire P embedded in the first guide groove 311 of the primary reducer 31. For example... Figure 1 As shown, viewed in the thickness direction d perpendicular to the flow direction a, the elastic line P is embedded in the bottom (left side) of the secondary reducer 32, and then in the top (right side) of the primary reducer 31. In some embodiments, the elastic line P is embedded in the top (right side) of the secondary reducer 32, and then in the bottom (left side) of the primary reducer 31.

[0113] like Figure 1 and Figure 6As shown, before the operation of the elastic wire deceleration clamping and braking system of the present invention, the elastic wire P is fed in the flow direction a of the elastic wire conveying. The elastic wire P is guided by the upstream guide roller 1 and enters between the first inclined surface 2111 and the second inclined surface 221 of the clamping and braking device 2. After passing through the clamping and braking device 2, the elastic wire P is embedded in the second guide groove 321 of the secondary reducer 32, and then passes through the secondary reducer to the downstream primary reducer 31. The elastic wire P is embedded in the first guide groove 311 of the primary reducer 31. The elastic wire P continues to be fed downstream under the guidance of the downstream guide roller 1'. The downstream guide roller 1' on the downstream side of the primary reducer 31 can be very close to the primary reducer 31 or very far away from the primary reducer 31, depending on the actual process requirements.

[0114] like Figure 1 and Figure 6 As shown, when the elastic line P is being conveyed normally, the elastic line P is conveyed downstream under tension. The elastic line P passes between the first inclined surface 2111 and the second inclined surface 221 of the clamping and braking device 2. Under the tension of the elastic line P, the clamping member 22 is driven to move towards the outlet O of the first chute 211, so that the second inclined surface 221 moves away from or contacts the first inclined surface 2111.

[0115] Specifically, in this embodiment, when the elastic line P moves downstream, the tension of the elastic line P causes the clamping member 22 to move towards the outlet O of the first slide groove 211. When the elastic tension of the elastic line P changes, the clamping member 22 will reciprocate up and down according to the magnitude of the tension of the elastic line P.

[0116] like Figure 7 As shown, when the elastic line P breaks at the break point P', the elastic line P located upstream of the break point P' retracts upstream due to the loss of tension and is decelerated by the secondary reducer 32. The direction of retraction upstream is defined as the retraction direction c. In this invention, the retraction direction c refers to the direction opposite to the flow direction a of the elastic line P.

[0117] In this embodiment, the secondary reducer 32 is a guide wheel structure, with a second guide groove 321 for embedding the elastic wire P along the width direction b. When the elastic wire P breaks, the elastic wire P located upstream of the breakage point P' is wound onto the second guide groove 321 of the secondary reducer 32, thus slowing down the speed at which the broken elastic wire P retracts upstream. Under the action of gravity, the clamping member 22 of the clamping braking device 2 moves towards the inlet I of the first slide groove 211, causing the second inclined surface 221 to contact the first inclined surface 2111, thereby stopping the movement of the elastic wire P disposed between the first inclined surface 2111 and the second inclined surface 221, so that the elastic wire P no longer retracts upstream.

[0118] Example 2.

[0119] The difference between this embodiment and Embodiment 1 is that the first-stage reducer 31 is a guide wire structure.

[0120] like Figure 8 and Figure 9 As shown, in this embodiment, the primary reducer 31 is a guide wire structure, and the secondary reducer 32 is a guide wheel structure. Along the flow direction a of the elastic line P, the primary reducer 31 has an opening 312 for the elastic line P to pass through. In the width direction b, the secondary reducer 32 has a second guide wire groove 321.

[0121] The elastic wire P is embedded in the second guide groove 321 of the secondary reducer 32, and then winds around the secondary reducer 32 to the primary reducer 31. The elastic wire P passes through the opening 312 of the primary reducer 31.

[0122] like Figure 8 and Figure 9 As shown, before the operation of the elastic wire deceleration clamping and braking system of the present invention, the elastic wire P is fed in the flow direction a of the elastic wire conveying. The elastic wire P is guided by the upstream guide roller 1 and enters between the first inclined surface 2111 and the second inclined surface 221 of the clamping and braking device 2. After passing through the clamping and braking device 2, the elastic wire P is embedded in the second guide groove 321 of the secondary reducer 32, and then winds through the secondary reducer 32 to the downstream primary reducer 31. The elastic wire P passes through the opening 312 of the primary reducer 31. The elastic wire P continues to be fed downstream under the guidance of the downstream guide roller 1'.

[0123] like Figure 8 and Figure 9 As shown, when the elastic line P is being conveyed normally, the elastic line P is conveyed downstream under tension. The elastic line P passes between the first inclined surface 2111 and the second inclined surface 221 of the clamping and braking device 2. Under the action of the elastic tension of the elastic line P, the clamping member 22 is driven to move towards the outlet O of the first chute 211, so that the second inclined surface 221 moves away from or contacts the first inclined surface 2111.

[0124] Specifically, in this embodiment, when the elastic line P moves downstream, the tension of the elastic line P causes the clamping member 22 to move towards the outlet O of the first slide groove 211. When the elastic tension of the elastic line P changes, the clamping member 22 will move up and down reciprocally according to the magnitude of the elastic tension.

[0125] When the elastic line P breaks at the break point P', the elastic line P located upstream of the break point P' retracts upstream due to the loss of tension and is wound and decelerated by the secondary reducer 32 or the primary reducer 31.

[0126] like Figure 10As shown, in some cases, when the elastic line P breaks at the elastic line break point P', the elastic line P located upstream of the elastic line break point P' retracts upstream (retraction direction c) due to the disappearance of tension, and is wound and decelerated by the first-stage decelerator 31.

[0127] In this embodiment, the first-stage reducer 31 is a wire guide structure. The elastic wire P located upstream of the break point P' of the elastic wire retracts upstream and winds into the opening 312 of the first-stage reducer 31, thus slowing down the speed at which the elastic wire P retracts upstream. Under the action of gravity, the clamping member 22 of the clamping braking device 2 moves towards the inlet I of the first slide groove 211, causing the second inclined surface 221 to contact the first inclined surface 2111, thereby stopping the movement of the elastic wire P disposed between the first inclined surface 2111 and the second inclined surface 221, so that the elastic wire P no longer retracts upstream.

[0128] like Figure 11 As shown, in other cases, when the elastic line P continues to retract in the retraction direction c without being wound and decelerated by the first-stage reducer 31, the elastic line P can also be wound and decelerated by the second-stage reducer 32, thus slowing down the speed at which the elastic line P that has broken off retracts upstream. Therefore, the second-stage reducer 32 prevents further deceleration if the first-stage reducer 31 fails to achieve deceleration, effectively setting up two deceleration processes to ensure that the clamping and braking success rate of the clamping and braking device 2 reaches 100%.

[0129] When the elastic wire P breaks, the first inclined surface 2111 and the second inclined surface 221 in the clamping and braking device 2 clamp and brake the elastic wire P. Therefore, if the first inclined surface 2111 and the second inclined surface 221 are made of elastic material, the friction between the elastic material and the elastic wire P can reduce the retraction speed of the elastic wire P, resulting in a good clamping and braking effect on the elastic wire P. In this embodiment, since a dual deceleration component is provided, the selection of the material of the first inclined surface 2111 and the second inclined surface 221 is not very important. For example, metal, nylon, aluminum alloy, or elastic material can all meet the requirements of the elastic wire breaking deceleration clamping and braking system of this invention. The materials of the first inclined surface 2111 and the second inclined surface 221 are also applicable to Embodiment 1 and Embodiment 3.

[0130] The other structures in this embodiment are the same as in Embodiment 1, and will not be described again here.

[0131] Example 3.

[0132] The difference between this embodiment and Embodiments 1 and 2 is that the first-stage reducer 31 is a rotatable guide rod structure, and the second-stage reducer 32 is a rotatable guide rod structure.

[0133] like Figure 12 and Figure 13As shown, in this embodiment, the primary reducer 31 is a rotatable guide rod structure, and the secondary reducer 32 is a rotatable guide rod. Along the flow direction of the elastic line P, the elastic line P winds around the guide rod of the secondary reducer 32, and then winds through the secondary reducer 32 back to the guide rod of the primary reducer 31.

[0134] The elastic line P winds around one side of the guide rod of the second-stage reducer 32, which is the opposite of the elastic line winding around P towards the guide rod of the first-stage reducer 31. For example... Figure 12 As shown, viewed in the thickness direction d perpendicular to the flow direction a, the elastic line P winds around the bottom (left side) of the secondary reducer 32 and then around the top (right side) of the primary reducer 31. In some embodiments, the elastic line P winds around the top (right side) of the secondary reducer 32 and then around the bottom (left side) of the primary reducer 31.

[0135] like Figure 12 and Figure 13 As shown, before the operation of the elastic wire deceleration clamping and braking system of the present invention, the elastic wire P is fed in the flow direction a of the elastic wire conveying. The elastic wire P is guided by the upstream guide roller 1 and enters between the first inclined surface 2111 and the second inclined surface 221 of the clamping and braking device 2. After passing through the clamping and braking device 2, the elastic wire P is wound around one side of the guide bar of the secondary reducer 32 to the guide bar of the primary reducer 31. Then, the elastic wire P continues to be fed downstream under the guidance of the downstream guide roller 1'.

[0136] like Figure 12 and Figure 13 As shown, when the elastic line P is being conveyed normally, the elastic line P is conveyed downstream under tension. The elastic line P passes between the first inclined surface 2111 and the second inclined surface 221 of the clamping and braking device 2. Under the action of the elastic tension of the elastic line P, the clamping member 22 is driven to move towards the outlet O of the first chute 211, so that the second inclined surface 221 moves away from or contacts the first inclined surface 2111.

[0137] Specifically, in this embodiment, when the elastic line P moves downstream, the tension of the elastic line P causes the clamping member 22 to move towards the outlet O of the first slide groove 211. When the elastic tension of the elastic line P changes, the clamping member 22 will move up and down reciprocally according to the magnitude of the elastic tension.

[0138] like Figure 14 As shown, when the elastic line P breaks at the break point P', the elastic line P located upstream of the break point P' retracts upstream (along the retraction direction c) due to the disappearance of tension, and is wound and decelerated by the secondary reducer 32.

[0139] In this embodiment, the first-stage reducer 31 is a rotatable guide rod structure, and the second-stage reducer 32 is a rotatable guide rod structure. The elastic line P located above the break point P' of the elastic line retracts upstream and wraps around the outer surface of the guide rod structure of the second-stage reducer 32, thus slowing down the speed at which the elastic line P retracts upstream. Under the action of gravity, the clamping member 22 of the clamping braking device 2 moves towards the inlet I of the first slide groove 211, causing the second inclined surface 221 to contact the first inclined surface 2111, thereby stopping the movement of the elastic line P disposed between the first inclined surface 2111 and the second inclined surface 221, so that the elastic line P no longer retracts upstream.

[0140] The other structures in this embodiment are the same as in Embodiment 1, and will not be described again here.

[0141] Example 4.

[0142] The difference between this embodiment and Embodiment 1 is that the clamping and braking device 2 is different.

[0143] Combination Figures 15 to 21 According to an embodiment of the present invention, an elastic wire breakage deceleration clamping and braking system, which is preset upstream of the elastic wire breakage point P', includes: a clamping and braking device 2 and a deceleration device 3 arranged sequentially along the flow direction a of the elastic wire P. The deceleration device 3 is located upstream of the elastic wire breakage point P'.

[0144] Furthermore, upstream guide roller 1 and downstream guide roller 1' are arranged along the flow direction a of the elastic line P. Upstream guide roller 1 is arranged upstream of clamping and braking device 2, and downstream guide roller 1' is arranged downstream of deceleration device 3.

[0145] The elastic line P is conveyed along the flow direction a of the elastic line, and is sequentially conveyed to the downstream side via the upstream guide roller 1, the clamping and braking device 2, the deceleration device 3 and the downstream guide roller 1'.

[0146] like Figure 16 , Figure 17 , Figure 18 and Figure 19 As shown, the clamping and braking device 2 includes a retaining seat 21, a clamping member 22, and a fixing member 23.

[0147] The retainer 21 has a first chute 211 in the flow direction a along the elastic line, the first chute 211 having an inlet I and an outlet O along the flow direction a; wherein, along the thickness direction d perpendicular to the flow direction a, the size of the outlet O is larger than the size of the inlet I.

[0148] The elastic line P enters the first chute 211 through the inlet I and extends out of the first chute 211 through the outlet O, and is conveyed downstream along the flow direction a of the elastic line.

[0149] The clamping member 22 is configured to reciprocate along the flow direction a of the elastic line conveying in the first chute 211; when the elastic line P breaks at the break point of the elastic line, the clamping member 22 moves towards the inlet I of the first chute 211 under the action of gravity, and stops the elastic line P from retracting upstream in the retraction direction.

[0150] Specifically, the retaining seat 21 has a first chute 211 formed along the flow direction a of the elastic line. The inner surface of the first chute 211 is a first conical surface 2111', which forms an inlet I and an outlet O along the flow direction a of the elastic line. The outlet O is larger than the inlet I along the thickness direction perpendicular to the flow direction a.

[0151] The clamping member 22 includes a clamping body 223, which has a second conical surface 221' that matches the first conical surface 2111'. An elastic line P is disposed between the first conical surface 2111' and the second conical surface 221'. The clamping body 223 is configured to reciprocate within the first groove 211 along the flow direction a of the elastic line.

[0152] When the elastic line P is being conveyed normally, under the tension of the elastic line P, the clamping body 223 is driven to move towards the outlet O of the first chute 211, so that the second conical surface 221' moves away from or contacts the first conical surface 2111'.

[0153] When the elastic line P breaks at the break point P', the clamping body 223 moves towards the inlet I of the first chute 221 under the action of gravity, causing the second conical surface 221' to contact the first conical surface 2111', thereby stopping the movement of the elastic line P positioned between the first conical surface 2111' and the second conical surface 221', so that the elastic line P no longer retracts upstream.

[0154] In this embodiment, the first conical surface 2111' and the second conical surface 221' are matching conical surfaces.

[0155] like Figure 16 and Figure 19 As shown, the clamping and braking device 2 also includes a fixing member 23. The fixing member 23 is disposed at the outlet of the first slide groove 211 and limits the reciprocating motion of the clamping body 223 in the first slide groove 211 along the flow direction a of the elastic line, so as to prevent the clamping body 223 from sliding out of the first slide groove 211.

[0156] The other structures in this embodiment are the same as in Embodiment 1, and will not be described again here.

[0157] Example 5.

[0158] The difference between this embodiment and Embodiment 2 lies in the clamping and braking device 2. The clamping and braking device 2 in this embodiment is the same as that in Embodiment 4. For example... Figures 22 to 25 As shown, the other structures in this embodiment are the same as those in Embodiment 2, and will not be described again here.

[0159] Example 6.

[0160] The difference between this embodiment and Embodiment 3 lies in the clamping braking device 2. The clamping braking device 2 in this embodiment is the same as that in Embodiment 4. For example... Figures 26 to 28 As shown, the other structures in this embodiment are the same as those in Embodiment 3, and will not be described again here.

[0161] In this invention, a deceleration device 3 is arranged along the flow direction a of the elastic line P. The deceleration device 3 is located downstream of the clamping and braking device 2 and upstream of the point where the elastic line breaks off (P'). By slowing down the speed at which the elastic line P retracts upstream after the breakage, the deceleration device 3 enables the clamping and braking device 2 to effectively clamp the elastic line P after the breakage, achieving a clamping and braking probability of nearly 100%. The clamping and braking device 2 plays a significant role, greatly reducing the downtime for pulling the elastic line P.

[0162] The manufacturing equipment for disposable hygiene products includes at least one set of elastic thread breakage deceleration clamping and braking system, the position of which can be determined according to the easy-break station of the elastic thread P.

[0163] This invention discloses a small-sized, electrically controlled, and mechanically-operated elastic wire deceleration and braking system for cutting off materials. It is applicable to manufacturing equipment for disposable hygiene products. Furthermore, it can be installed at any desired location, unconstrained by process flow or space limitations, significantly reducing the time required to catch the elastic wire and thus improving equipment production efficiency.
