Description

Technical Field

[0001] The utility model relates to the field of quilting machines, in particular to a roller structure device of a quilting machine. Background Art

[0002] A quilting machine is a textile machine used to sew linear patterns on the surfaces of mattresses, bedspreads, quilts, etc.; quilting machines used for sewing quilts can be divided into two categories according to the number of needles and the number of sewing patterns: straight quilting machines and computer quilting machines. Straight quilting machines usually have 7 needles, 9 needles, and 11 needles. This type of quilting machine can only sew straight lines; computer quilting machines are single-needle designs, and use a computer visual interface to control the movement of the machine to achieve pattern sewing; when using existing quilting machines, a drum structure is required to press the mattresses, bedspreads, quilts, etc. that need to be quilted. When the drum structure of the existing quilting machine is used, the mattresses, bedspreads, quilts, etc. that need to be quilted are pressed. The mattress, bedspread, quilt, etc. that need to be quilted are placed on the workbench of the quilting machine, and the roller frame is driven by a motor to move, which in turn drives the roller on the roller frame to move, and the moving roller continues to press the mattress, bedspread, quilt, etc. that need to be quilted. However, during the pressing process, the rotating roller will inevitably drive the mattress, bedspread, quilt, etc. that need to be quilted to move, which will affect the pressing effect; if during pressing, a fixed structure is used to fix the mattress, bedspread, quilt, etc. that need to be quilted before pressing, this will cause the part that contacts the fixed structure to be unable to be pressed, resulting in uneven pressing. For this reason, we propose a quilting machine roller structure device. Utility Model Content

[0003] The utility model aims to provide a quilting machine roller structure device, including a double-wire screw, the double-wire screw is threadedly connected to the inner sides of two groups of roller frames, a group of rollers are rotatably installed on the two groups of roller frames, one end of the double-wire screw is rotatably connected to a support plate one through a bearing, the other end of the double-wire screw is fixedly connected to the driving end of a motor one, the motor one is fixedly installed on a support plate two, and the support plates one and two are both fixedly connected to the moving parts in the auxiliary assembly.

[0004] Preferably, two groups of guide rods 1 are fixedly installed between the support plate 1 and the support plate 2, and the guide rods 1 slide through the inner sides of the two groups of roller frames.

[0005] Preferably: the auxiliary component includes a moving part, the moving part is slidably connected to the inner side of the limit frame, the inner side of the moving part is threadedly connected with a screw, the screw is rotatably connected to the inner wall of the limit frame through a bearing, the other end of the screw is fixedly connected to the driving end of motor 2, the motor 2 is fixedly installed on the limit frame, two groups of guide rods 2 are fixedly installed between the inner walls of the limit frame, and the guide rods 2 slide through the inner side of the moving part.

[0009] Preferably, a group of support and limit plates are fixedly mounted on the inner walls of the two groups of storage sleeves, and a through hole is opened in the middle of the support and limit plates.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. When the utility model is used, the motor is started to drive the double-thread screw to rotate. The rotation of the double-thread screw will drive the two sets of roller frames to move away from each other, and then the two sets of rollers will move away from each other. The rollers can press the quilted mattresses, bedspreads, quilts, etc. during the movement. During the pressing process, since the two sets of rollers move away from each other, the two sets of rollers will generate dragging force on the mattresses, bedspreads, quilts, etc. that need to be quilted. The two dragging forces are roughly the same and will cancel each other out, and will not drive the mattresses, bedspreads, quilts, etc. that need to be quilted to move.

[0012] 2. After pressing for many times, there is a gap between the bottom of the two sets of rollers when the two sets of roller frames are in contact. The mattresses, bedspreads, quilts, etc. that need to be quilted in this empty part cannot be pressed. At this time, start motor 2 to drive the screw to rotate. The rotation of the screw will drive the moving part to move. The movement of the moving part will drive support plate 1 and support plate 2, so that the positions of the two sets of rollers can be adjusted, so that the mattresses, bedspreads, quilts, etc. that need to be quilted in the empty part can be pressed, thereby using uniform pressing.

[0018] Reference Figure 1 - Figure 3 The utility model discloses a roller structure device for a quilting machine, comprising a double-wire screw 2, wherein the double-wire screw 2 is threadedly connected to the inner sides of two groups of roller frames 1, and a group of rollers 3 are rotatably mounted on the two groups of roller frames 1, and one end of the double-wire screw 2 is rotatably connected to a support plate 4 through a bearing, and the other end of the double-wire screw 2 is fixedly connected to the driving end of a motor 5, and the motor 5 is fixedly mounted on a support plate 2 6, and the support plate 1 4 and the support plate 2 6 are both fixedly connected to a moving part 701 in an auxiliary component 7.

[0019] Two sets of guide rods 8 are fixedly installed between the support plate 1 4 and the support plate 2 6. The guide rods 8 slide through the inner sides of the two sets of roller frames 1. The two sets of guide rods 8 can support the two sets of roller frames 1 and provide guidance for the movement of the two sets of roller frames 1.

[0020] The auxiliary component 7 includes a moving part 701, which is slidably connected to the inner side of the limit frame 702. A screw 703 is threadedly connected to the inner side of the moving part 701. The screw 703 is rotatably connected to the inner wall of the limit frame 702 through a bearing. The other end of the screw 703 is fixedly connected to the driving end of a motor 2 704. The motor 2 704 is fixedly installed on the limit frame 702. Two groups of guide rods 2 705 are fixedly installed between the inner walls of the limit frame 702. The guide rods 2 705 slide through the inner side of the moving part 701. When in use, the motor 2 704 is started to drive the screw 703 to rotate. The rotation of the screw 703 will drive the moving part 701 to move. The movement of the moving part 701 will drive the support plate 1 4 and the support plate 2 6, so that the positions of the two groups of rollers 3 can be adjusted.

[0021] Two groups of lifting components 9 are fixedly installed at the bottom of the limit frame 702, and the two groups of lifting components 9 are fixedly installed on the top of the base 10. The height of the limit frame 702 can be adjusted by the two groups of lifting components 9, and then the height of the two groups of rollers 3 can be adjusted; it should be noted that during the production of the base 10 and the lifting components 9, the weight of the base 10 and the lifting components 9 must be controlled to prevent the entire device from tipping over.

[0022] A plurality of sets of self-locking universal wheels 11 are evenly mounted on the bottom of the base 10 to facilitate movement and fixing of the device.

[0023] The lifting assembly 9 includes a storage sleeve 901, and a hydraulic cylinder 902 is installed at the bottom end of the inner wall of the storage sleeve 901. The telescopic end of the hydraulic cylinder 902 is fixedly connected to the bottom of the lifting rod 903. The top of the lifting rod 903 slides through the top of the storage frame 901 and is fixedly connected to the bottom of the limit frame 702. The storage sleeve 901 is fixedly installed on the top of the base 10. When in use, according to the use requirements, the hydraulic cylinder 902 is started to drive the lifting rod 903 to move up and down, and the lifting rod 903 moves up and down to drive the limit frame 702 to move up and down, thereby adjusting the two groups of rollers 3 to a suitable height.

[0024] A group of support and limit plates 12 are fixedly installed on the inner walls of the two groups of storage sleeves 901. A through hole is opened in the middle of the support and limit plates 12. The storage sleeves 901 are arranged to limit the moving range of the lifting rod 903. When the device is not in use, the hydraulic cylinder 902 drives the lifting rod 903 to move downward, so that the lifting rod 903 contacts the support and limit plates 12. The lifting rod 903 is supported by the support and limit plates 12, thereby relieving the supporting pressure of the hydraulic cylinder 902.

[0025] Working principle of the utility model: when in use, the device is moved and driven to a suitable position, and the mattress, bedspread, quilt, etc. that need to be quilted are placed on the workbench of the quilting machine. At this time, the two groups of roller frames 1 are in contact with each other. According to the use requirements, the hydraulic cylinder 902 is started to drive the lifting rod 903 to move up and down, and the lifting rod 903 moves up and down to drive the limit frame 702 to move up and down, and then the two groups of rollers 3 are adjusted to a suitable height, and the motor 15 is started to drive the double-wire screw 2 to rotate. The rotation of the double-wire screw 2 will drive the two groups of roller frames 1 to move away from each other, and then the two groups of rollers 3 will move away from each other. The rollers 3 can press the quilted mattress, bedspread, quilt, etc. during the movement. During the pressing process, since the two groups of rollers 3 are away from each other, the two groups of rollers 3 will generate dragging force on the mattress, bedspread, quilt, etc. that need to be quilted. The two dragging forces are roughly the same and will offset each other, and will not drive the mattress, bedspread, quilt, etc. that need to be quilted. The quilted mattress, bedspread, quilt, etc. are moved; after pressing once, the hydraulic cylinder 902 is used to drive the roller 3 to move up and away from the mattress, bedspread, quilt, etc. that need to be quilted, and then the motor 1 5 is started to drive the two groups of rollers 3 to reset, so that the two groups of roller frames 1 are in contact with each other again, and then the hydraulic cylinder 902 is used to drive the roller 3 to move down and continue pressing; after pressing for many times, since the two groups of roller frames 1 are in contact, there is a gap between the bottoms of the two groups of rollers 3, and the mattress, bedspread, quilt, etc. that need to be quilted in this empty part cannot be pressed. At this time, the motor 2 704 is started to drive the screw 703 to rotate, and the rotation of the screw 703 will drive the moving part 701 to move, and the movement of the moving part 701 will drive the support plate 1 4 and the support plate 2 6, so that the position of the two groups of rollers 3 can be adjusted, so that the empty part of the mattress, bedspread, quilt, etc. that need to be quilted can be pressed, thereby using uniform pressing.

[0026] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions.
