Description

Technical Field

[0001] This utility model relates to the field of textile equipment technology, and more specifically to a cutting mechanism for a winding machine. Background Technology

[0002] In the textile operation process, after the knitting machine finishes weaving the fabric, the fabric is usually pulled to the winding machine. The winding machine is used to roll the fabric onto the winding roller. After winding, the fabric is cut by the cutting mechanism. Then the winding roller is taken out and transported to the storage area.

[0003] Currently, the cutting mechanism on winding machines generally uses a hydraulic system to drive the cutting device. This hydraulic system includes a hydraulic cylinder, whose piston rod is driven by a slider. The slider slides into a sliding groove on the base of the winding machine. A sliding seat is mounted on the slider, and the cutting device is mounted on the sliding seat. Thus, the extension and retraction of the piston rod of the hydraulic cylinder drives the sliding seat, causing the cutting device to move back and forth, thereby cutting the fabric. However, using the above-mentioned hydraulic system to drive the cutting device results in a complex structure and cumbersome installation because it requires components such as a hydraulic pump, oil tank, and oil circuit. Furthermore, the piston rod of the hydraulic cylinder needs to be connected to the cutting device through a transmission structure (i.e., the cooperating slider and sliding groove), which poses a risk of bending and deformation during long-term use.

[0004] In view of this, this application has conducted in-depth research on this basis, resulting in this case. Utility Model Content

[0005] The purpose of this invention is to provide a cutting mechanism for a winding machine that is simple in structure and installation, occupies little space, and has good rigidity.

[0006] To achieve the above objectives, the solution of this utility model is:

[0007] A cutting mechanism for a winding machine, the winding machine including a winding base and a cutting mechanism, with the conveying direction of the fabric during winding as front to back and the horizontal and vertical directions as left and right. The cutting mechanism includes a cutting device and a rodless cylinder mounted on the rear side of the winding base. The cylinder barrel of the rodless cylinder has a cutting groove arranged in the left-right direction. The cutting groove is equipped with a sliding block, and the sliding block is connected to the piston of the rodless cylinder. The cutting device includes a cutting motor, a cutting blade, and an auxiliary component. The cutting blade is mounted on the output shaft of the cutting motor. The auxiliary component includes a cutting auxiliary plate and a guide plate mounted on the cutting auxiliary plate. The cutting motor is mounted on the sliding block through the cutting auxiliary plate. The cutting auxiliary plate has cutting strip holes that cooperate with the cutting blade. The side of the guide plate opposite to the cutting blade is set as an inclined side for guiding the fabric in.

[0008] The winding base includes a base, and a discharge rail for the winding roller to fall down is connected to the rear side of the base. The cylinder of the rodless cylinder is embedded in the connection position between the base and the discharge rail; or the cylinder of the rodless cylinder is embedded in the front side of the discharge rail.

[0009] The upper side of the discharge rail is connected to the upper side of the cylinder of the rodless cylinder.

[0010] The first side of the cutting auxiliary plate extends out of the sliding block, and the cutting strip hole is located on the first side of the cutting auxiliary plate.

[0011] The cutting motor is mounted on the cutting auxiliary plate, and the output shaft of the cutting motor is located on the front side of the housing of the cutting motor.

[0012] The first side of the guide plate extends to the cutting strip hole, the second side of the guide plate is located outside the sliding block, and the second side of the guide plate is an inclined side that is arranged downward in a direction away from the cutting blade.

[0013] It also includes a guiding device, which includes a guide belt and a guide seat. The guide seat is located on the rear side of the cylinder of the rodless cylinder, and the two are arranged close to each other. The guide seat has a guide groove arranged in the left-right direction. The guide belt is laid flat in the guide groove, and one end of the guide belt is fixedly installed on the housing of the cutting motor.

[0014] With the above structure, this utility model has the following beneficial effects: This utility model uses a rodless cylinder and a cutting device in cooperation. The slider on the rodless cylinder is directly assembled with the cutting device. The cutting device moves left and right under the action of the rodless cylinder without the need for intermediate transmission components, which improves the rigidity between the slider and the cutting device. Combined with the inclined side of the guide plate in the cutting device, the inclined side can guide the fabric into the space between the cutting auxiliary plate and the cutting blade, making it convenient for the cutting blade to cut the fabric. Compared with the prior art, the rodless cylinder in this utility model has fewer components, a simpler structure, and is easier to install. Furthermore, the cooperation between the auxiliary components and the cutting blade guides the fabric, which in turn facilitates precise cutting by the cutting blade, thereby improving the stability and cutting effect of the cutting.

[0024] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0025] A cutting mechanism for a winding machine, which is an improvement on a conventional fabric winding machine, for example, can be the fabric winding machine mentioned in Chinese Patent Publication No. CN211644018U, entitled A Novel Fabric Cutting Device for Fabric Winding Machines.

[0026] For ease of description, the conveying direction of the fabric roll in this embodiment is from front to back.

[0027] like Figure 1 As shown - Figure 3 As shown, the fabric rolling machine used in this embodiment includes a fabric rolling base for mounting the weaving equipment and a main control device. The fabric rolling base includes a base and supports 12a erected on both sides of the base 1. A fabric pushing mechanism 20a and a fabric rolling mechanism 30a are installed between the two supports 12a. The cutting mechanism 100 is located behind the fabric pushing mechanism 20a. In this embodiment, the fabric pushing mechanism 20a and the fabric rolling mechanism 30a are both mechanisms used on conventional fabric rolling machines, so they will not be described in detail. The rear side of the base is conventionally equipped with or connected to a discharge rail 40a, which is used for the winding roller that has been wound up to fall onto it.

[0028] The aforementioned main control device includes an operation panel (not shown in the figure) and a control system (not shown in the figure). The operation panel is used to send signals, and the control system is used to receive signals and convert them into results. The control system is used to receive and / or send control signals generated according to configuration information. The control system is electrically connected to the fabric pushing mechanism 20a, the fabric rolling mechanism 30a, and the cutting mechanism 100, respectively. In this embodiment, the main control device adopts a conventional main control device, and its signal reception and control are conventional operations, so they will not be described in detail.

[0029] The improvement of this utility model lies in the improvement of the cutting mechanism, as described below.

[0030] The aforementioned cutting mechanism 100 includes a rodless cylinder 1 and a cutting device. The cylinder barrel of the rodless cylinder 1 is fixedly mounted on the rear side of the base, and the cylinder barrel of the rodless cylinder 1 is arranged in a left-right direction. A cutting groove 11 arranged in a left-right direction is opened on the upper side of the rodless cylinder 1. The left and right ends of the cutting groove 11 extend to the corresponding brackets 12a, and a sliding block 12 is slidably mounted on the cutting groove 11. The sliding block 12 is connected to the piston of the rodless cylinder 1, and the cutting device is fixedly mounted on the sliding block 12. The cutting device is used to cut the fabric. Thus, when the piston of the rodless cylinder 1 moves, it drives the sliding block 12 to slide along the cutting groove 11, thereby driving the cutting device to slide. When the piston of the rodless cylinder 1 moves in the opposite direction, it drives the sliding block 12 to slide in the opposite direction along the cutting groove 11, thereby driving the cutting device to slide in the opposite direction.

[0031] Specifically, the cylinder of the rodless cylinder 1 can be fitted into the front side of the discharge rail 40a. That is, the front side of the discharge rail 40a is provided with a mounting groove, which is a through groove that connects the left and right sides. The mounting groove is adapted to the cylinder of the rodless cylinder 1, and the cylinder of the rodless cylinder 1 is embedded in the mounting groove. Preferably, the upper side of the discharge rail 40a is connected to the upper side of the cylinder of the rodless cylinder 1 so that the take-up roller can roll into the rear side of the discharge rail 40a.

[0032] Furthermore, in this embodiment, the cylinder barrel of the rodless cylinder 1 can also be embedded in the connection position between the base and the discharge rail 40a. This embedding method is the same as the embedding structure described above, so it will not be described in detail again. It should be noted that the installation position of the cylinder barrel of the rodless cylinder 1 is set according to the actual situation.

[0033] like Figure 1 As shown - Figure 2 As shown, the cutting device includes a cutting motor 21, a cutting blade 22, and an auxiliary component 23. The cutting blade 22 is conventionally mounted on the output shaft of the cutting motor 21 to rotate in conjunction with the output shaft of the cutting motor 21. The cutting blade 22 is located on the rear side of the housing of the cutting motor 21. The auxiliary component includes a cutting auxiliary plate 31 and a guide plate 32 for guiding. The cutting motor 21 is mounted on the sliding block 12 through the cutting auxiliary plate 31. The cutting auxiliary plate 31 has a cutting strip hole 311 that cooperates with the cutting blade 22. The guide plate 32 is fixedly mounted on the cutting auxiliary plate 31, and the side of the guide plate 32 facing away from the cutting blade 22 has an inclined side 321 for guiding the fabric in.

[0034] Specifically, the cutting auxiliary plate 31 is fixedly installed on the upper side of the sliding block 12. The cutting auxiliary plate 31 is arranged in the left-right direction. Here, the cutting auxiliary plate 31 is installed on the upper side of the sliding block 12 in a conventional manner. For example, multiple pairs of corresponding mounting holes are opened on the cutting auxiliary plate 31 and the sliding block 12 respectively, and bolts or screws are screwed into each pair of corresponding mounting holes. Preferably, the cutting auxiliary plate 31 extends in the left-right direction, and the first side of the cutting auxiliary plate 31 extends out of the sliding block 12. In this embodiment, the first side of the cutting auxiliary plate 31 is taken as the left side for illustration. The cutting strip hole 311 on the cutting auxiliary plate 31 is located on the left side of the cutting auxiliary plate 31. When the cutting blade 22 is in the stopped rotating state, the lowest point of the cutting blade 22 is in clearance fit with the cutting strip hole 311 so that the cutting blade 22 can cut.

[0035] Furthermore, the aforementioned cutting motor 21 is mounted on the cutting auxiliary plate 31, and the cutting motor 21 is closer to the left side of the cutting auxiliary plate 31. The output shaft of the cutting motor 21 is located on the front side of the housing of the cutting motor 21. In this embodiment, the cutting motor 21 is mounted on the cutting auxiliary plate 31 in a conventional manner. For example, a vertically arranged connector 312 is integrally connected to the left side of the cutting auxiliary plate 31. The connector 312 can be a connecting plate, a connecting seat, etc. The connector 312 is located to the left of the cutting strip hole 311. The cutting auxiliary plate 31 is installed together with the cutting motor 21 through the connector 312. The installation structure adopts an existing conventional structure. For example, multiple pairs of corresponding mounting holes are opened between the connector 312 and the housing of the cutting motor 21. Each pair of mounting holes is screwed with conventional fasteners such as bolts and screws. Preferably, to ensure the stability of the installation of the cutting motor 21, part or all of the bottom of the housing of the cutting motor 21 is placed on the cutting auxiliary plate 31.

[0036] Furthermore, the aforementioned guide plate 32 is arranged in the left-right direction and extends in the left-right direction. The left side of the guide plate 32 extends to the cutting strip hole 311, and the right side of the guide plate 32 extends to the outside of the sliding block 12. The right side of the guide plate 32 is an inclined side, that is, the right side of the guide plate 32 is inclined downward from left to right. At this time, both the upper and lower sides of the guide plate 32 are inclined surfaces, and there is a gap between the right side of the guide plate 32 and the upper side of the cylinder of the rodless cylinder 1 to avoid the guide plate 32 affecting the sliding. Preferably, the left side of the guide plate 32 extends to the middle position of the cutting strip hole 311. At this time, the left side of the guide plate 32 is provided with an avoidance groove 321 to the right. The avoidance groove 321 matches the cutting strip hole 311 to further guide the fabric into the cutting range of the cutting blade 22 to ensure the cutting effect.

[0037] As a preferred embodiment, to ensure that the cutting device does not easily deviate during left and right sliding, the cutting mechanism 100 further includes a guide device, which includes a guide belt 41 and a guide seat 42 arranged in the left and right direction. The guide seat 42 is located on the rear side of the cylinder of the rodless cylinder 1. The guide seat 42 and the cylinder of the rodless cylinder 1 are arranged side by side and close to each other. The guide seat 42 is embedded in the mounting groove of the discharge rail 40a in the same way as the cylinder of the rodless cylinder 1. The upper side of the guide seat 42 is provided with a guide groove 421 arranged in the left and right direction. The guide groove 421 is U-shaped. The guide belt 41 is laid flat in the guide groove 421, and the left end of the guide belt 41 is fixedly installed on the left side of the housing of the cutting motor 21. The two adopt conventional mounting structures such as existing bolts or pins. In this way, when the rodless cylinder 1 is activated, the cutting device slides to the right, which drives the guide belt 42 out of the guide groove 421; when the rodless cylinder 1 is activated in the opposite direction, the cutting device slides to the left, which drives the guide belt 42 back into the guide groove 421; thus ensuring that the cutting device slides in a straight line during the sliding process.

[0038] It should be noted that the working process of the above-mentioned winding machine is the same as that of a conventional winding machine. The only difference is that the cutting structure is different. In addition, in a conventional winding machine, the winding roller that has been wound up is pushed into the discharge rail 40a by the fabric pushing mechanism. At this time, the unwound fabric is still in the corresponding rotating roller. Therefore, the fabric is still in a relatively taut state, which facilitates the cutting mechanism 100 of this embodiment to cut it.

[0039] The present invention discloses a cutting mechanism for a winding machine. The working process is as follows: the rodless cylinder 1 is activated, causing the piston of the rodless cylinder 1 to drive the sliding block 12 to slide to the right. The sliding block 12 slides to the right along the direction of the cutting groove to drive the cutting motor to slide to the right. During the sliding process, the inclined side on the guide plate 32 can guide the fabric to gradually and smoothly enter the cutting range of the cutting blade 22 for cutting. The cutting strip hole 311 here serves to avoid the blade. Then, after the cutting motor 21 slides to the right end of the rodless cylinder 1, the piston of the rodless cylinder 1 moves in the opposite direction, so that the cutting motor 21 moves to the left under the drive of the sliding block 12. When it returns to the original initial position (i.e., the left end position of the rodless cylinder 1), the rodless cylinder 1 stops operating, thereby completing the cutting of the fabric and separating the fabric on the winding roller that has been wound up from the unwound fabric, which facilitates the subsequent handling of the winding roller.

[0040] The above description is only a preferred embodiment of this invention. All equivalent changes and modifications made within the scope of the claims of this utility model shall fall within the scope of the claims of this utility model.
