Description

Technical Field

[0001] The invention belongs to the technical field of clothing machinery, and in particular relates to a lower edge stripping device of a cloth stretching machine with a cloth pressing function. Background Art

[0002] The lower stripping device mentioned above refers to the upper stripping device. The upper stripping device is arranged on both sides of the oblique spreading part of the cloth stretching machine when in use, that is, an upper stripping device is arranged on both sides of the corresponding oblique spreading part of the cloth stretching machine. For the concept of the oblique spreading part, please refer to the Chinese patent CN102602729B mentioned below; the lower stripping device is arranged on both sides of the cloth cutting mechanism (also called "cloth cutting mechanism") corresponding to the cloth stretching machine when in use. In view of the above, the industry also calls the upper stripping device a primary stripping device or a primary spreading device, and the lower stripping device is called a secondary stripping device or a secondary spreading device in the same case. The function of the upper and lower stripping devices can be known from their noun interpretations, that is, they are to strip the curled edges of the two side edges in the length direction of the cloth, which are mostly formed in the process of fabric finishing and other processes with a rope-like effect.

[0003] Technical information related to the stripping device of a cloth pulling machine can be found in the disclosed Chinese patent documents, such as the "front spreading device for a cloth pulling machine" recommended by CN201942894U mentioned above, the "rear spreading device for a cloth pulling machine" provided by CN201923692U and the "knitted fabric stripping device for a cloth pulling machine" introduced in CN102602729B, etc.

[0004] The stripping devices disclosed in the patent documents above are not limited to each other. Although each has a corresponding technical effect, there is a common disadvantage that the position of the stripping device cannot be adjusted (i.e., cannot be changed). As is known in the textile and clothing industry, the curling degree of knitted textile fabrics of different textures is different, and some fabrics, such as double-faced velvet fabrics, basically do not have curling. Therefore, if the stripping device is used to strip the edges without distinction, the following undesirable situations often occur: First, for knitted textile fabrics that are easy to curl and have a serious degree of curling, after the upper stripping device strips the curling once, after the fabric passes through the lower stripping device and is stripped twice by the lower stripping device, it is still difficult to achieve the desired effect of fully stripping the fabric edge (the industry calls it incomplete stripping); second, for knitted textile fabrics that are not easy to curl and have a relatively slight degree of curling, especially for high-grade knitted textile fabrics, although the curling can be fully stripped, there is a risk of damaging the fabric; third, for knitted textile fabrics that have no curling and do not need to be stripped, such as the aforementioned double-faced velvet fabric, the stripping device becomes redundant and even causes unnecessary interference.

[0005] The above three technical problems are fully solved by the technical solution of "lower edge stripping device of cloth pulling machine" given in CN108557551A, and CN108557551A objectively realizes the technical effects recorded in the technical effect column of its description. However, CN108557551A still has the following shortcomings: because the cloth has a certain degree of softness and flowiness, when the cloth guide roller guides the cloth to be stripped and makes the cloth edge pass through the stripping tooth belt (the patent calls it "lower edge stripping tooth belt"), it is often difficult to make the curled edge area of ​​the cloth close to the stripping tooth belt, which seriously affects the stripping effect, especially the cloth with soft texture and serious curling edge cannot meet the industry's expectations after being stripped by the lower edge stripping device. In view of the above situation, it is necessary to make further improvements, and the technical solution to be introduced below is produced in this context. Summary of the invention

When in use, the cloth guide plate 50 is fixed between the left and right wall panels 10, 20 of the cloth stretching frame, and the cloth guide plate 50 is inclined toward the left and right stripping toothed belts 1, 3.

[0025] As the technical key points of the technical solution provided by the present invention, the structural system of the aforementioned lower edge stripping device also includes a cloth pressing roller 5, a left tensioning and releasing mechanism 6 of a cloth pressing roller shaft, a right tensioning and releasing mechanism 7 of a cloth pressing roller shaft, a chain reel driving mechanism 8 and a cloth pressing roller driving mechanism 9. The cloth pressing roller 5 is rotatably arranged on, that is, rotatably supported on, a cloth pressing roller supporting shaft 51, and the left end of the cloth pressing roller 5 corresponds to the front side of the length direction of the aforementioned left edge stripping toothed belt 1, and the right end of the cloth pressing roller 5 corresponds to the front side of the length direction of the aforementioned right edge stripping toothed belt 3. The left end of the aforementioned cloth pressing roller supporting shaft 51 passes through the left wall panel 10 of the aforementioned cloth tensioning frame and is connected to the left tensioning and releasing mechanism 6 of the cloth pressing roller shaft and is also connected to the left tensioning and releasing mechanism 6 of the cloth pressing roller shaft.

[0040] See you next time Figure 1 and Figure 2 The aforementioned chain reel drive mechanism 8 includes a chain reel drive motor 81 and a chain reel drive reduction box 82. The chain reel drive motor 81 and the chain reel drive reduction box 82 are transmission-coordinated and the chain reel drive reduction box 82 is fixed together with the chain reel drive motor 81 at the position corresponding to the aforementioned left limit sleeve guide plate 102 on the front right side of the aforementioned left wall panel 10 of the cloth stretching frame.

[0041] In the present embodiment, the aforementioned chain reel driving motor 81 is a motor with forward and reverse rotation functions; the aforementioned first position signal collector I 65 and second position signal collector II 66 are travel switches, but may also be micro switches.

[0042] When the chain reel driving motor 81 is working, for example, when working clockwise, it drives the chain reel driving reduction box 82, and the final power output shaft 821 of the chain reel driving reduction box drives the aforementioned chain reel 64 to rotate clockwise, and the chain reel 64 winds up the left traction chain 63. Since the left traction chain 63 is wound up by the chain reel 64, the left tension spring 61 is forced to stretch and store energy, and at this time the left traction plate 62 moves forward, driving the left shaft head 517 of the cloth pressing roller support shaft to also move forward.

The degree of clockwise rotation of the aforementioned chain reel 64 is determined by the contact foot of the first position signal collector I615 entering the aforementioned signal collector contact foot matching groove 642, that is, when the contact foot of the first position signal collector I615 is at a degree corresponding to the signal collector contact foot matching groove 642, the first position signal collector I615 feeds back a signal to the electrical controller, and the electrical controller issues a command to stop the cloth pressing roller driving motor 91.

[0043] After the cloth 60 feeding operation is completed, the online operator operates the switch of the electrical controller to make the aforementioned cloth pressing roller driving motor 91 work in the reverse direction, and the chain reel 64 moves in the reverse direction to make the left traction chain 63 previously wound thereon withdraw. According to the aforementioned reverse process, the left and right tension springs 61 and 71 are restored, so that the cloth pressing roller support shaft 51 moves backward, and the cloth pressing roller 5 moves in the direction of the left stripping toothed belt 1 and the right stripping toothed belt 3, so that the cloth 60 is closely attached to the left stripping toothed belt 1 and the right stripping toothed belt 3. In the aforementioned process, the cloth pressing roller 5 is in a state of being driven and rotated by the cloth pressing roller driving mechanism 9.

The cloth pressing roller driving active wheel 93 is fixed on the aforementioned cloth pressing roller driving motor shaft 911. One end of the cloth pressing roller driving transmission belt 94 is sleeved on the cloth pressing roller driving active wheel 93, and the other end is sleeved on the cloth pressing roller driving driven wheel 95, and the cloth pressing roller driving driven wheel 95 is fixed to the right end of the aforementioned cloth pressing roller 5.

[0045] When the cloth pressing roller driving motor 1 is working, the cloth pressing roller driving motor shaft 911 drives the cloth pressing roller driving active wheel 93, which drives the cloth pressing roller driving driven wheel 95 through the cloth pressing roller driving transmission belt 94, and the cloth pressing roller driving driven wheel 95 drives the cloth pressing roller 5 to rotate, thereby leading (leading out) the cloth 60 downward.

[0046] In this embodiment, the cloth pressing roller driving active wheel 93 and the cloth pressing roller driving driven wheel 95 are pulleys, and the cloth pressing roller driving transmission belt 94 is a transmission belt.

In the aforementioned process, when the cloth passes through the upper stripping device 70, the upper stripping toothed belt 701 is driven by the upper stripping toothed belt driving mechanism of the structural system of the upper stripping device 70, and the curling edges on both sides of the cloth 60 are stripped and unfolded by the upper stripping toothed belt 701, completing one stripping. When the cloth 60 reaches the workstation of the cloth pulling machine with a cloth pressing function of the present invention, a second stripping is performed, that is, in the process of the cloth 60 being drawn out from the cloth roll 601 and cut by the cloth cutting mechanism 90, when the cloth 60 passes through the left stripping toothed belt 1 and the right stripping toothed belt 3, the curling edges with a rope-like tendency at the edge of the cloth 60 are stripped and unfolded.
