Description

Technical Field

[0001] This application relates to unwinding clamping structures, and more particularly to an unwinding clamping structure for an inner lining belt, belonging to the technical field of sewing auxiliary tools. Background Technology

[0002] Many garments require lining tape to be wrapped in the fabric to help shape them during the sewing process. This means that the lining tape on the tape tray needs to be fed into the sewing machine during the sewing process.

[0003] The current structure of the inner lining tape reel is very simple. A circular tray is fixed on the central shaft. The drum in the center of the inner lining tape reel is inserted into the central shaft and placed on the tray. During the feeding process, the drum in the center of the inner lining tape reel rotates around the central shaft. As the inner lining tape reel rotates, the drum in the center of the inner lining tape reel rubs against the central shaft. At the same time, the bottom surface of the inner lining tape reel rubs against the upper surface of the tray, making the inner lining tape reel less flexible in rotation, with high resistance to rotational friction, and also generating a lot of noise.

[0004] Therefore, there has long been a need for an inner liner unwinding clamping structure that allows the inner liner reel to rotate flexibly, with low rotational friction resistance, smooth inner liner feeding, and low noise during the inner liner reel rotation process. Summary of the Invention

[0005] The purpose of this application is to provide a reasonably structured inner lining tape unwinding and clamping structure, which allows the inner lining tape reel to rotate flexibly, with low rotational friction resistance, smooth inner lining tape feeding, and low noise during the process of rotating and unwinding the inner lining tape.

[0006] To achieve the objectives of the above application, the technical solution of this application is: an inner lining tape unwinding and clamping structure, comprising a fixed platform, characterized in that: a fixed seat is installed and fixed on the fixed platform, a vertically arranged support rod is fixed on the fixed seat, a bearing is sleeved on the support rod, a rotating disk is connected to the outer ring of the bearing, an outward clamping member is installed on the rotating disk, and the clamping member can clamp and fix an inner lining tape reel, on which the inner lining tape is wound.

[0007] Furthermore, the fixing base includes a U-shaped clamping clamp, a fastening screw, and a sleeve. The U-shaped clamping clamp is held on the edge of the fixing platform. The lower clamping plate of the U-shaped clamping clamp has a through hole with internal threads, and a fastening screw is screwed into the through hole. A vertically arranged sleeve is fixed on the side of the U-shaped clamping clamp.

[0008] Furthermore, a support rod is inserted into the sleeve, and a through hole with internal threads is provided on the side wall of the sleeve, with a locking screw screwed into the through hole.

[0009] Furthermore, the inner ring of the bearing is connected to the support rod.

[0010] Furthermore, the clamping component includes a compression spring, a push rod, and a clamping plate. Multiple evenly spaced holes are provided on the outer circumferential surface of the rotating disk. A compression spring is installed in each hole. The push rod is inserted into the hole. One end of the compression spring is connected to the bottom of the hole, and the other end of the compression spring is connected to the inner end of the push rod. The outer end of the push rod is connected to the clamping plate.

[0011] Furthermore, the push rod is hollow inside, with an open inner end that communicates with the interior, and a closed outer end. One end of the compression spring is inserted through the inner opening of the push rod and connected to the inner wall of the outer end of the push rod.

[0012] Furthermore, the clamping plate is an arc-shaped piece.

[0013] Furthermore, a guide plate is connected to the upper end of the clamping plate.

[0014] The beneficial effects of this application are:

[0015] 1. This application installs an outward-pushing clamping member on the outer circumferential surface of the rotating disk. The clamping member clamps the inner liner tape disc, and the rotating disk rotates around the support rod through the central bearing. In this way, during the feeding process, the inner liner tape disc and the rotating disk rotate together through the central bearing around the support rod, resulting in less rotational friction, more flexible rotation, and less noise.

[0016] 2. This application has a reasonable structure. The support rod is fixed to the fixed platform by a locking screw, allowing for easy adjustment of the support rod's height, which in turn facilitates the adjustment of the height of the inner lining reel. A guide plate is connected to the upper end of the clamping plate of the clamping component. During the process of inserting the inner lining reel into the clamping component, the curved surface of the guide plate guides the reel, allowing it to be smoothly inserted into the clamping component, making operation convenient.

[0022] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] See Figures 1 to 4 The present application discloses an inner lining tape unwinding and clamping structure, comprising a fixed platform 1, characterized in that: a fixed seat is installed and fixed on the fixed platform 1, a vertically arranged support rod 6 is fixed on the fixed seat, a bearing 7 is sleeved on the support rod 6, a rotating disk 8 is connected to the outer ring of the bearing 7, a clamping member is installed on the rotating disk 8 to clamp outwards, and the clamping member can clamp and fix an inner lining tape reel 14, on which an inner lining tape 15 is wound.

[0024] The fixing base includes a U-shaped clamping clamp 2, a fastening screw 3, and a sleeve 4. The U-shaped clamping clamp 2 is clamped on the edge of the fixing platform 1. The lower clamping plate of the U-shaped clamping clamp 2 has a through hole with internal threads, and the fastening screw 3 is screwed into the through hole. The sleeve 4 is fixed vertically on the side of the U-shaped clamping clamp 2.

[0025] The support rod 6 is inserted into the sleeve 4. A through hole with internal thread is opened on the side wall of the sleeve 4, and a locking screw 5 is screwed into the through hole.

[0026] The inner ring of the bearing 7 is connected to the support rod 6.

[0027] The clamping component includes a compression spring 10, a push rod 11, and a clamping plate 12. Multiple holes 9 are evenly spaced on the outer circumferential surface of the rotating disk 8. A compression spring 10 is installed in each hole 9. The push rod 11 is inserted into the hole 9. One end of the compression spring 10 is connected to the bottom of the hole 9, and the other end of the compression spring 10 is connected to the inner end of the push rod 11. The outer end of the push rod 11 is connected to the clamping plate 12.

[0028] The push rod 11 is hollow inside, with an open inner end that communicates with the interior and a closed outer end. One end of the compression spring 10 is inserted through the open inner end of the push rod 11 and connected to the inner wall of the outer end of the push rod 11.

[0029] The clamping plate 12 is an arc-shaped piece.

[0030] The upper end of the clamping plate 12 is connected to a guide plate 13.

[0031] This application features an outwardly pushing clamping member mounted on the outer circumferential surface of a rotating disk. The clamping member holds the inner liner reel, and the rotating disk rotates around a support rod via a central bearing. During the feeding process, the inner liner reel and the rotating disk rotate together via the central bearing around the support rod, resulting in low rotational friction, more flexible rotation, and lower noise. The specific structure of this application is as follows:

[0032] A fixed base is detachably installed on the fixed platform 1 of the sewing machine. The fixed base is used to support and fix the vertically set support rod 6. The fixed base includes a U-shaped clamping clip 2, a fastening screw 3, a sleeve 4, and a locking screw 5. The opening of the U-shaped clamping clip 2 is inserted into the edge of the fixed platform 1. The lower clamping plate of the U-shaped clamping clip 2 has a through hole with internal threads. The fastening screw 3 is screwed into the through hole. The fastening screw 3 presses against the lower plate surface of the fixed platform 1, thereby installing and fixing the U-shaped clamping clip 2 on the fixed platform 1.

[0033] A vertically arranged sleeve 4 is fixed on the outer surface of the U-shaped clamping clamp 2. The lower end of the support rod 6 is inserted into and passes through the sleeve 4. A through hole with internal threads is opened on the side wall of the sleeve 4. A locking screw 5 is screwed on the through hole. The support rod 6 is pressed by the locking screw 5, thereby fixing the support rod 6 to the sleeve 4. At the same time, the height of the support rod 6 can be easily adjusted by loosening the locking screw 5.

[0034] A bearing 7 is fitted onto the support rod 6, and a rotating disk 8 is fitted onto the bearing 7. The inner ring of the bearing 7 is fixed to the support rod 6, and the outer ring of the bearing 7 is fixed to the rotating disk 8. The rotating disk 8 rotates around the support rod 6 via the bearing 7. An outward clamping device is installed on the rotating disk 8, which includes a compression spring 10, a push rod 11, and a clamping plate 12. Multiple evenly spaced deep holes 9 are formed on the outer circumference of the rotating disk 8. Compression springs 10 are filled into the holes 9, with one end of the compression spring 10 connected to the bottom of the hole 9 and the other end of the compression spring 10 connected to the push rod 11.

[0035] The push rod 11 has a hollow interior, with one end open and the other end closed. The open end of the push rod 11 is inserted into the hole 9, while the other end of the compression spring 10 is inserted into the inner cavity of the push rod 11 and connected to the inner wall of the closed end of the push rod 11.

[0036] A clamping plate 12 is connected to the outer end of the push rod 11. Pushing the clamping plate 12 causes it to push the push rod 11 to compress the compression spring 10. Under the force of the compression spring 10, the clamping plate 12 has an outward clamping force. The center of the inner lining tape reel 14 is a drum. Multiple clamping plates 12, evenly arranged on the outer side of the rotating disk 8, push and clamp the inner wall of the central drum of the inner lining tape reel 14, thereby clamping and fixing the inner lining tape reel 14 to the outer side of the rotating disk 8. The clamping plate 12 is an arc-shaped piece, which increases the contact surface between the clamping plate 12 and the central drum of the inner lining tape reel 14, thereby increasing the friction between the clamping plate 12 and the central drum of the inner lining tape reel 14, making the clamping of the inner lining tape reel 14 more stable.

[0037] To facilitate clamping the inner lining reel 14 onto the clamping member outside the rotating disk 8, a guide plate 13 is connected to the upper end of the clamping plate 12. The guide plate 13 is an arc-shaped plate with a smooth surface, and the upper ends of multiple guide plates 13 approach the support rod 6, thus giving the guide plate 13 an arc-shaped slope from top to bottom. As the central reel of the inner lining reel 14 is inserted downward from the upper end of the guide plate 13, the central reel of the inner lining reel 14 squeezes the guide plate 13, thereby gradually causing the clamping plate 12 to push the push rod 11 to compress the compression spring 10. The inner lining reel 14 is then conveniently clamped onto the clamping member outside the rotating disk 8 via the guide plate 13.

[0038] The inner lining belt 15 is wound on the inner lining belt reel 14. During the feeding process, the inner lining belt 15 on the inner lining belt reel 14 and the rotating disk 8 rotate together around the support rod 6 through the central bearing 7. Compared with the traditional method of letting the central drum of the inner lining belt reel 14 rotate around the support rod 6 by friction, the rotation through the bearing 7 results in less friction, more flexible rotation, and less noise.

[0039] The above description is a further detailed explanation of this application in conjunction with specific embodiments. It should not be considered that the specific implementation of this application is limited to these descriptions. For those skilled in the art, there will be various simple substitutions, improvements and changes to this application without departing from the concept of this application. All such simple substitutions, improvements and changes should be considered to fall within the protection scope of this application.
