Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric production, in particular to a safety switch device for a water spunlace machine. Background Art

[0002] The production of non-woven fabrics requires the use of a spunlaced machine, which usually belongs to a linkage device system. The production line with a spunlaced machine has a long process flow. The cotton layer must pass through the net curtain, the stranding and other parts. It often takes 6 to 7 hours to produce a roll of cloth. Due to the long production of the machine, the net curtain and the round drum are easy to stick. If the operator is not careful when handling, it is easy to be brought into the machine with the net curtain and the round drum, thus causing an accident. At the same time, due to improper operation, it is easy for other objects (such as tools, etc.) to enter the production end of the spunlaced machine. If an equipment accident occurs, the economic loss is incalculable. Therefore, an emergency pull-wire switch can be set on the spunlaced machine for emergency braking to improve the safety of the production line. However, since the trigger point of the emergency pull-wire is the trigger wire, and the trigger wire is usually set longer to facilitate flexible triggering at different positions, the staff is easy to touch the trigger wire when working next to the spunlaced machine. If the emergency pull-wire switch is accidentally touched, it will cause the spunlaced machine to stop for no reason, thus affecting normal production. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-6 The utility model discloses a safety switch device for a water spunlace machine, including a pull-wire switch 1 and an anti-accidental touch shell. The pull-wire switch 1 includes a trigger pull wire 12. The pull-wire switch 1 works after the trigger pull wire 12 is touched. The pull-wire switch 1 is installed on the water spunlace machine. When the trigger pull wire 12 is triggered, the water spunlace machine will be shut down. The anti-accidental touch shell is also arranged on the water spunlace machine. The anti-accidental touch shell is used to surround the trigger pull wire 12 so that the trigger pull wire 12 will not be accidentally touched. The anti-accidental touch shell includes a mounting plate 2 mounted on the water spunlace machine and two protective plates 3 hingedly arranged on the upper and lower sides of the mounting plate 2.

[0026] In one embodiment, a torsion spring is installed at the connection between each protective plate 3 and the mounting plate 2. The torsion spring is used to reset the protective plate 3 so that the corresponding protective plate 3 and the mounting plate 2 remain in a vertical state. The device also includes a linkage device, one end of the linkage device is arranged on the trigger wire 12, and the other end of the linkage device is connected to the protective plate 3. The linkage device is used to drive the trigger wire 12 to be triggered when the protective plate 3 rotates to the side away from the trigger wire 12.

[0027] In a specific implementation, the pull-cord switch 1 is used for emergency braking of the water spunlace machine, and the anti-accidental-touch shell surrounds the trigger cord 12 of the pull-cord switch 1. Under normal circumstances, when the staff is working next to the water spunlace machine, it will not affect the trigger cord 12 protected by the anti-accidental-touch shell. When an emergency situation occurs and the water spunlace machine needs to be braked, the staff only needs to rotate the protective plate 3 to the side away from the trigger cord 12. At this time, the linkage device works and drives the trigger cord 12 to be triggered, so that the circuit in the pull-cord switch 1 is disconnected, thereby stopping the water spunlace machine. The device can be convenient for the staff to trigger it at any time, and will not be accidentally touched when it is not needed, so as to facilitate actual use.

[0028] It is understandable that a brightly colored paint can be applied on the anti-mistaken-touch housing, so that the staff can always pay attention to it and remind the staff to pay attention to safety.

[0029] In one embodiment, the pull-cord switch 1 includes a switch body 11, a trigger pull cord 12 is installed at the trigger end of the switch body 11, the length of the trigger pull cord 12 is adapted to the length of the water spurting machine, so that the staff can flexibly trigger it next to the water spurting machine, and a mounting platform 13 is installed at the end of the trigger pull cord 12 away from the switch body 11. The switch body 11 and the mounting platform 13 are both arranged on the water spurting machine. The switch body 11 is electrically connected to the water spurting machine and is used to drive the water spurting machine to stop after the trigger pull cord 12 is pulled.

[0030] With this design, when the spunlace machine encounters an unexpected situation and needs to be shut down urgently, the staff only needs to be near the spunlace machine where they can touch the trigger pull cord 12, and they can quickly control the spunlace machine to shut down urgently through the pull cord switch 1, thereby improving the safety of the production process.

[0031] In one embodiment, the linkage device includes a connecting ring 6 mounted on the trigger wire 12, a mounting frame 4 mounted on the side of the protective plate 3 close to the trigger wire 12, and a connecting rod 5 hingedly mounted on the mounting frame 4, and the end of the connecting rod 5 away from the mounting frame 4 is connected to the connecting ring 6.

[0032] With such a design, when the protective plate 3 is turned and opened by the staff to the side away from the trigger wire 12, the connecting rod 5 will move synchronously, and the other end of the connecting rod 5 will pull the connecting ring 6, so that the trigger wire 12 is pulled synchronously, thereby starting the switch body 11. In addition, the protective plate 3 and the trigger wire 12 are the same length, and any position that can trigger the trigger wire 12 can also synchronously adjust the protective plate 3. Therefore, the device can ensure that the trigger wire 12 will not be accidentally touched, and will not affect the trigger range of the pull-wire switch 1 itself.

[0033] In one embodiment, the switch body 11 has two trigger ends, and a trigger pull wire 12 is installed at each of the trigger ends. The number of linkage devices is two and they are respectively matched with two protective plates 3 and the trigger pull wire 12. A handle 7 is installed on the top protective plate 3, and a push frame 8 is installed on the bottom protective plate 3.

[0034] With this design, the handle 7 can be used to cooperate with the staff's hand to contact and open the corresponding protective plate 3, and the pushing frame 8 is used to cooperate with the staff's legs to contact and open another corresponding protective plate 3, thereby further improving the flexibility of use of the device. When the staff's hands are inconvenient, they can also use their legs to quickly drive the bottom protective plate 3 to rotate and open.

[0035] In one embodiment, a temporary limit device 9 is provided on the mounting platform 13, and the temporary limit device 9 is used to temporarily limit the protective plate 3 when it is not rotated and adjusted. It should be noted that the force of the limit is smaller than the force used by the staff to drive the protective plate 3 to rotate, and is mainly used to prevent the staff from contacting the protective plate 3 without reason and triggering the pull-wire switch 1.

[0036] In one embodiment, the temporary limiting device 9 includes a shell 91, a wedge block 92 slidably installed at one end in the shell 91, a spring is provided in the shell 91, the other end of the spring is in contact with the wedge block 92, and a fixed block 10 cooperating with the wedge block 92 is installed on the protective plate 3.

[0037] With such a design, when the protective plate 3 is pulled by the tension spring and is in a closed state, the wedge block 92 is pushed by the spring to contact the surface of the fixed block 10, so that the protective plate 3 is difficult to be touched by mistake. When an emergency shutdown is required, the staff rotates the protective plate 3. At this time, the fixed block 10 moves synchronously, contacts the inclined surface of the protective plate 3 and pushes the wedge block 92 to retract into the shell 91, so that the protective plate 3 can trigger the pull-wire switch 1. The adjustment process is convenient and efficient, so as to facilitate practical use.

[0038] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0039] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0040] In addition, "plurality" means two or more.

[0041] The above description 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 protection scope of the present invention.
