Description

Technical Field

[0001] The present application relates to the technical field of warping machines, and in particular to a protective door of a warping machine. Background Art

[0002] Warping machine is a machine used in the textile industry, which is mainly divided into two categories: batch warping machine and sectional warping machine. Among them, sectional warping machine is mainly used to cut and trim wide fabrics, such as cutting wide fabrics into narrow fabrics, or trimming and finishing irregular fabrics. The main working principle of sectional warping machine is to pass a wide fabric through a set of guide rollers and cutting knives, cut it into narrow fabrics, and trim and finish it at the same time.

[0003] However, when the existing sectional warping machine is in use, the textile material is wound up by the weaving shaft, and no protection is provided at the weaving shaft position or only simple protection is provided by a cross bar. The weaving shaft rotates continuously during the winding process, and the rotating weaving shaft is directly exposed to the surrounding environment. The staff can directly contact the rotating weaving shaft, which can easily cause safety accidents. Utility Model Content

[0004] The present application provides a protective door for a warping machine, which can provide good protection at the weaving shaft position and effectively prevent workers from contacting the rotating weaving shaft, thereby improving the safety of the warping machine during use.

[0005] The present application provides a protective door for a warping machine, which adopts the following technical solution:

[0006] A protective door of a warping machine is arranged on the warping machine, the warping machine comprises a machine body and a weaving shaft, the weaving shaft is rotatably connected to the machine body, and the rotation axis of the weaving shaft is horizontal; it comprises a door body, a plurality of slide rails, a positioning assembly and a locking assembly, the slide rails are arranged on the machine body, the door body is slidably connected to the slide rails, and the door body can pass through the side of the weaving shaft away from the feeding end of the machine body during sliding;

[0007] When the door body slides to the extreme position in the direction away from the weaving shaft, the side of the weaving shaft away from the feed end of the machine body is left empty, and the positioning assembly fixes the position of the door body; when the door body slides to the extreme position in the direction close to the weaving shaft, the door body is located on the side of the weaving shaft away from the feed end of the machine body, and the locking assembly fixes the position of the door body.

[0008] By adopting the above technical solution, when the door body is controlled to slide until the positioning assembly positions the door body, it is convenient for the staff to unload the weaving shaft, reducing the probability of safety accidents caused by the door body accidentally sliding due to external force during the unloading process of the weaving shaft; when the door body is controlled to slide until the locking assembly locks the door body, the door body can play a better protective effect on one side of the rotating weaving shaft, effectively preventing the staff from contacting the rotating weaving shaft, thereby improving the safety of the warping machine during use, and at the same time making it convenient for the staff to control the position of the door body.

[0009] Optionally, the positioning assembly includes a positioning member, a limiting member and a plurality of first elastic members; the limiting member is arranged on the machine body, located on the side of the door body close to the machine body, and located on one side of the weaving shaft; the positioning member is movably connected to the door body, and the moving direction of the positioning member is perpendicular to the sliding direction of the door body; the two ends of the first elastic member are respectively connected to the positioning member and the door body, and the first elastic member drives the positioning member to move in a direction close to the machine body;

[0010] When the positioning assembly fixes the position of the door body, the end of the positioning member close to the machine body is located on one side of the limiting member, the positioning member contacts and abuts against the limiting member, and the limiting member restricts the positioning member from moving in a direction close to the weaving shaft.

[0011] By adopting the above technical solution, when the door body is controlled to slide until the positioning assembly positions the door body, the limiting member limits the positioning member and a plurality of first elastic members can drive the positioning member to remain limited by the limiting member, thereby improving the stability and reliability of the positioning assembly in positioning the door body.

[0012] Optionally, the side of the limiting member facing away from the machine body has a contact surface for contacting with the end of the positioning member close to the machine body, the contact surface is an inclined surface, the contact surface is inclined in a direction close to the weaving shaft, and the distance between the end of the contact surface close to the weaving shaft and the door body is greater than the distance between the end of the contact surface away from the weaving shaft and the door body;

[0013] When the positioning member moves toward the direction close to the machine body to the extreme position, one end of the positioning member close to the machine body can contact and abut against the abutting surface.

[0014] By adopting the above technical solution, in the process of controlling the door body to slide until the positioning assembly positions the door body, after the positioning member contacts the abutment surface, the abutment surface will drive the positioning member to overcome the activities of the first elastic members, and finally enable the positioning member to pass over the limiting member and be located on the side of the limiting member away from the weaving shaft, so that the limiting member limits the positioning member, thereby enabling the positioning assembly to automatically position the door body, facilitating the use of the positioning assembly.

[0015] Optionally, the limiting member has a chamfer at one end of the abutting surface away from the weaving shaft.

[0016] By adopting the above technical solution, the wear of the positioning member and the limiting member during the process of the positioning assembly positioning the door body and contacting the door body can be reduced, thereby extending the service life of the positioning assembly, and enabling the positioning assembly to stably position the door body for a longer period of time.

[0017] Optionally, the positioning assembly further comprises a buffer, which is arranged on the machine body and is located on the same side of the weaving shaft as the limiting member;

[0018] When the door body slides to a limit position in a direction away from the weaving shaft, the door body contacts the buffer member.

[0019] By adopting the above technical solution, the buffer is used to limit the sliding of the door body, which makes it easy for the door body to stop sliding after being positioned by the positioning assembly. At the same time, it can reduce the impact between the door body and the buffer, thereby reducing the wear between the door body and the buffer.

[0020] Optionally, the positioning assembly further includes a plurality of second elastic members, two ends of which are respectively connected to the buffer member and the machine body, the buffer member is movably connected to the machine body, and the second elastic member drives the buffer member to move toward a direction close to the weaving axis;

[0022] By adopting the above-mentioned technical solution, the second elastic member and the buffer member cooperate to improve the buffering effect on the door body; at the same time, when the positioning assembly is controlled to release the positioning of the door body, the squeezed second elastic member releases the elastic force to drive the door body to slide toward the direction close to the locking assembly, thereby facilitating the staff to slide the door body toward the direction close to the locking assembly.

[0023] Optionally, the locking assembly includes a locking piece and a matching piece, wherein the matching piece is arranged on the machine body and located on one side of the door body, and a slot which is interference-fitted with the matching piece is formed at one end of the matching piece close to the door body;

[0024] When the door body slides to an extreme position in a direction close to the weaving shaft, the locking piece is plug-fitted into the matching piece.

[0025] By adopting the above technical solution, the door body can be locked after sliding until the locking piece is inserted into the slot, making the process of locking the door body by the locking assembly more convenient, and the locking assembly has a stronger locking effect on the door body.

[0026] Optionally, the locking assembly includes a first magnet and a second magnet, the first magnet is arranged on the door body, and the second magnet is arranged on the machine body;

[0028] By adopting the above technical solution, the door body can be locked after sliding until the first magnet contacts the second magnet, making the process of locking the door body by the locking assembly more convenient and enabling the staff to lock and unlock the door body through the locking assembly.

[0042] The following is combined with Figure 1-6 This application is described in further detail.

[0043] Embodiment 1:

[0044] An embodiment of the present application discloses a protective door of a warping machine, which protects workers at the discharge end of the warping machine and effectively prevents workers from contacting a rotating weaving shaft, thereby improving the safety of the warping machine during use.

[0045] Reference Figure 1 and Figure 2 The warping machine 1 includes a machine body 11 and a weaving shaft 12 for winding textile materials. The weaving shaft 12 is rotatably installed at the discharge end of the warping machine 1 with its axis horizontal; the weaving shaft 12 is driven by a corresponding motor to rotate and wind the textile materials, and the rotation axis of the weaving shaft 12 is perpendicular to the length direction of the warping machine 1. The weaving shaft 12 has a working space 13 on the side away from the feeding end of the machine body 11 for the staff to unload the wound textile materials, and the space is connected to the space where the weaving shaft 12 is located on the warping machine 1. In this embodiment, since the warping machine 1 is a common prior art in the art, it will not be described in detail here. Only part of the structure of the warping machine 1 is shown in the drawings and only briefly represented.

[0046] The protective door comprises a door body 2, a plurality of slide rails 3, a locking assembly 4 and a positioning assembly 5.

[0047] The door body 2 is a rectangular plate-shaped structure as a whole. The door body 2 is movably connected to the discharge end of the warping machine 1, and can form protection in the working space 13 on one side of the weaving shaft 12 or release the protection formed in the working space 13 during the movement of the door body 2.

[0048] Furthermore, it is preferred that the door body 2 has a plurality of observation windows 21. When the door body 2 moves to the working space 13 on one side of the weaving shaft 12 to form protection, the staff can observe the winding of the textile material on the weaving shaft 12 through the observation windows 21. In this embodiment, the observation windows 21 are preferably transparent glass windows.

[0049] Several slide rails 3 are fixedly installed at the discharge end of the machine body 11. In this embodiment, the protective door preferably includes a slide rail 3, and the slide rail 3 is preferably fixedly installed at the bottom of the machine body 11 away from the feed end in a position where the length direction is parallel to the rotation direction of the weaving shaft 12.

[0050] The door body 2 is installed above the slide rail 3 in a position state in which the length direction is parallel to the length direction of the slide rail 3, and the door body 2 is movably connected to the machine body 11 by slidingly connecting with the slide rail 3.

[0051] Furthermore, in order to facilitate the staff to control the door body 2 to slide along the slide rail 3, a handle 22 is provided on the side of the door body 2 away from the weaving shaft 12.

[0052] Reference Figure 2 and Figure 3 The locking assembly 4 includes a locking piece 41 and a matching piece 42 .

[0053] The locking member 41 is fixedly mounted on one side of the door body 2 in the length direction. When the door body 2 releases the protection of the working space 13 , the locking member 41 is located on the side of the door body 2 close to the working space 13 .

[0054] The matching piece 42 is fixedly installed on a side of the machine body 11 away from the feeding end. When the door body 2 releases the protection of the working space 13, the matching piece 42 is also located on a side of the door body 2 close to the working space 13.

[0055] A locking groove 421 matched with the locking piece 41 is provided on the side of the fitting piece 42 close to the working space 13. When the door body 2 slides to the extreme position in the direction close to the fitting piece 42 (that is, the door body 2 and the fitting piece 42 are in contact and abutment with each other), the locking piece 41 can be inserted into the locking groove 421. At this time, the locking piece 41 and the fitting piece 42 form an interference fit, and at this time, the door body 2 can form protection on the side of the weaving shaft 12 close to the working space 13.

[0056] Reference Figure 1 and Figure 4 The positioning assembly 5 includes a positioning member 51 , a plurality of first elastic members 52 and a limiting member 53 .

[0057] The positioning member 51 is movably mounted on the door body 2 . In this embodiment, the positioning member 51 is preferably movably connected to the door body 2 in a sliding connection manner, and the sliding direction of the positioning member 51 is preferably horizontal and perpendicular to the sliding direction of the door body 2 .

[0058] When the positioning member 51 slides relative to the door body 2 , the positioning member 51 always remains to penetrate the door body 2 , that is, both ends of the positioning member 51 in the length direction are respectively located on the two sides of the door body 2 .

[0059] The two ends of the first elastic member 52 are respectively fixedly connected to the door body 2 and the positioning member 51, and the first elastic member 52 can drive the positioning member 51 to slide to the limit position in the direction close to the machine body 11 and maintain it. In this embodiment, the first elastic member 52 is preferably a compression spring, and the positioning assembly 5 preferably includes a first elastic member 52.

[0060] The limiting member 53 is fixedly mounted on a side of the machine body 11 away from the feeding end, and the limiting member 53 is located on a side of the working space 13 away from the matching member 42 .

[0061] The limiting member 53 is a wedge-shaped block structure as a whole, and has a contact surface 531 for the positioning member 51 to contact on the side of the limiting member 53 facing away from the machine body 11. The contact surface 531 is a vertical surface and is an inclined surface relative to the sliding direction of the door body 2, and the distance between the end of the contact surface 531 close to the working space 13 and the machine body 11 is smaller than the distance between the end of the contact surface 531 away from the working space 13 and the machine body 11.

[0062] Furthermore, the stopper 53 has a chamfered structure at one end of the abutting surface 531 away from the working space 13, so as to reduce the wear between the positioning member 51 and the stopper 53. In this embodiment, the chamfered structure on the stopper 53 is preferably a rounded corner.

[0063] When the door body 2 slides from the position where it protects the working space 13 in the direction away from the fitting member 42, and the positioning member 51 is kept in the limit position under the action of the first elastic member 52, the end of the positioning member 51 close to the machine body 11 will abut against the abutting surface 531; at this time, as the door body 2 continues to slide, the positioning member 51 will overcome the action of the first elastic member 52 under the limiting action of the abutting surface 531 and slide in the direction away from the machine body 11 until the end of the positioning member 51 close to the machine body 11 is no longer in contact with the abutting surface 531, at which time the first elastic member 52 will drive the positioning member 51 to slide back to its original position, and at this time the end of the positioning member 51 close to the machine body 11 will be located on the side of the positioning member 53 away from the working space 13. At this time, the limiting member 53 limits the positioning member 51, that is, the sliding of the door body 2 in the direction close to the fitting member 42 is restricted; and at this time, the door body 2 is freed from the protection of the side of the weaving shaft 12 close to the working space 13.

[0064] The implementation principle of the protective door of a warping machine in the embodiment of the present application is:

[0065] When the warping machine 1 is to be operated, the staff controls the door body 2 to slide along the slide rail 3 toward the direction close to the matching piece 42, so that the locking piece 41 is inserted into the locking groove 421 and has an interference fit with the matching piece 42. At this time, the door body 2 can form a protection on the side of the weaving shaft 12 close to the working space 13 to protect the safety of the staff;

[0066] When it is necessary to unload the textile material rolled up on the weaving shaft 12, the staff controls the door body 2 to slide along the slide rail 3 toward the direction close to the limit piece 53, so that the end of the positioning piece 51 close to the machine body 11 is located on the side of the limit piece 53 away from the working space 13. At this time, the door body 2 releases the protection of the side of the weaving shaft 12 close to the working space 13 and is restricted from sliding toward the working space 13, which is convenient for the staff to start work at the working space 13.

[0067] Embodiment 2:

[0068] Reference Figure 3 and Figure 5 The difference between this embodiment and embodiment 1 lies in the locking component 4.

[0069] Reference Figure 5 The locking assembly 4 includes a first magnet 43 and a second magnet 44 that can be magnetically attracted. In this embodiment, preferably, both the first magnet 43 and the second magnet 44 are magnets. Since magnets are common in the prior art, they are not described here, and are only briefly shown in the drawings.

[0070] The first magnet 43 is fixedly mounted on the door body 2 , and the second magnet 44 is fixedly mounted on the machine body 11 . The second magnet 44 is located on a side of the machine body 11 away from the feed end and on a side of the working space 13 away from the limiting member 53 .

[0071] When the door body 2 slides to the extreme position in the direction close to the second magnet 44, the second magnet 44 will fit against the first magnet 43. The second magnet 44 not only limits the continued sliding of the door body 2, but also can position the door body 2 by adsorbing the first magnet 43 to itself.

[0072] The implementation principle of the protective door of a warping machine in the embodiment of the present application is:

[0073] When the warping machine 1 is to be operated, the staff controls the door body 2 to slide along the slide rail 3 in the direction close to the second magnet 44, so that the first magnet 43 and the second magnet 44 are in contact with each other. At this time, the second magnet 44 restricts the door body 2 from continuing to slide and positions the door body 2 by adsorbing the first magnet 43 on itself. At this time, the door body 2 can form a protection on the side of the weaving shaft 12 close to the working space 13 to protect the safety of the staff.

[0074] Embodiment 3:

[0075] Reference Figure 4 and Figure 6 The difference between this embodiment and embodiment 1 lies in the positioning component 5.

[0076] Reference Figure 2 and Figure 6 The positioning assembly 5 also includes an elastic buffer member 54 and a plurality of second elastic members 55 .

[0077] The buffer member 54 is movably mounted on a side of the machine body 11 away from the feed end, and the buffer member 54 is located on a side of the stop member 53 away from the working space 13. In this embodiment, the buffer member 54 is preferably made of rubber material.

[0078] After the door body 2 slides in the direction away from the fitting part 42 until the end of the positioning part 51 close to the machine body 11 is located on the side of the limit part 53 away from the working space 13, the door body 2 can contact and abut against the buffer part 54, thereby reducing the wear of the door body 2 and the machine body 11 caused by the collision between the door body 2 and the machine body 11.

[0079] The buffer member 54 is movably connected to the machine body 11 in a sliding connection manner, and the sliding direction of the buffer member 54 is parallel to the sliding direction of the door body 2 .

[0080] The plurality of second elastic members 55 are all located on the side of the buffer member 54 away from the limit member 53, and the two ends of the second elastic member 55 are respectively fixedly connected to the buffer member 54 and the body 11, and the plurality of second elastic members 55 can drive the buffer member 54 to slide to the limit position in the direction close to the limit member 53 and maintain it. In this embodiment, the second elastic member 55 is preferably a common spring.

[0081] When the door body 2 slides in a direction away from the matching piece 42 until the end of the positioning piece 51 close to the body 11 is located on the side of the limiting piece 53 away from the working space 13, the door body 2 will contact the buffer piece 54 and drive the buffer piece 54 to slide in a direction away from the limiting piece 53, so that the plurality of second elastic pieces 55 are all in a squeezed state. At this time, the plurality of second elastic pieces 55 have a tendency to drive the door body 2 to slide in a direction close to the matching piece 42, and at this time, the end of the positioning piece 51 close to the body 11 is kept against the side of the limiting piece 53 away from the working space 13.

[0082] Afterwards, the force of the first elastic member 52 is overcome to control the positioning member 51 to slide in the direction away from the machine body 11, so that the end of the positioning member 51 close to the machine body 11 is separated from the side of the limiting member 53 away from the working space 13, and the second elastic members 55 will restore their original state and drive the door body 2 to slide in the direction close to the matching member 42, so as to facilitate the door body 2 to slide to the side of the weaving shaft 12 close to the working space 13 to form a protection.

[0083] The implementation principle of the protective door of a warping machine in the embodiment of the present application is:

[0084] When it is necessary to unload the textile material wound on the weaving shaft 12, the staff controls the door body 2 to slide along the slide rail 3 toward the direction close to the limiter 53, so that the end of the positioning member 51 close to the machine body 11 is located on the side of the limiter 53 away from the working space 13. At this time, the door body 2 contacts and abuts against the buffer member 54 and squeezes the second elastic members 55, thereby reducing the wear of the door body 2 during the sliding process. At this time, the door body 2 releases the protection of the side of the weaving shaft 12 close to the working space 13 and is restricted from sliding toward the working space 13, so that the staff can work at the working space 13.

[0085] Afterwards, when the warping machine 1 is to be operated, the staff controls the positioning member 51 to slide in the direction away from the machine body 11. After the positioning member 51 is out of contact with the limiting member 53, the door body 2 will slide in the direction close to the matching member 42 under the action of a number of second elastic members 55, making it convenient for the staff to control the door body 2 to slide along the slide rail 3 in the direction close to the limiting member 53.

[0086] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
