Description

Technical Field

[0001] The present application relates to the technical field of sewing machine installation equipment, and in particular to an auxiliary installation mechanism for a conveyor belt pulley of a sewing machine. Background Art

[0002] The sewing machine belt pulley is a key component in the machine, connecting to the motor via a belt to transmit power to other parts of the sewing machine. The pulley typically consists of a rim, web, hub, and pulley mounting bracket.

[0003] After removing the pulleys of a sewing machine conveyor belt for belt replacement or other reasons, when reinstalling it, the pulley on one end of the pulley must be pulled far enough to straighten the belt. The tightening pulley mounting base is then secured to the sewing machine using bolts, thereby securing the pulley in place. In the prior art, workers typically tighten the pulley manually, but this is laborious and can easily lead to injury. Utility Model Content

[0004] In order to improve the convenience of tensioning the pulley, the present application provides a sewing machine conveyor belt pulley auxiliary installation mechanism.

[0005] The present application provides a sewing machine conveyor belt pulley auxiliary installation mechanism that adopts the following technical solutions:

[0007] By adopting the above technical solution, when tensioning the belt on the sewing machine, the first mounting plate can be fixed to the sewing machine through the fixing assembly, so that the end of the slide rod outside the slide groove abuts against the pulley mounting seat, and then the screw is rotated to move along the axial direction of the threaded tube in the threaded tube, so that the screw pushes the slide rod to move, and then the slide rod drives the pulley mounting seat to move on the sewing machine. In this way, a single person can tension the belt with less force, which improves the convenience of tensioning the pulley and saves manpower.

[0008] Optionally, one end of the sliding rod disposed outside the sliding hole is fixedly connected to a triangle iron for abutting against a pulley mounting seat.

[0009] By adopting the above technical solution, the triangular iron can be used to abut against the pulley mounting seat, thereby increasing the abutment area between the slide bar and the pulley mounting seat, thereby facilitating the movement of the pulley mounting seat.

[0010] Optionally, a reinforcement plate is fixed inside the triangle iron.

[0011] By adopting the above technical solution, the triangle iron can be reinforced by the reinforcement plate to improve its bending resistance.

[0012] Optionally, an abutment block is fixedly connected to one end of the screw rod close to the sliding rod.

[0013] By adopting the above technical solution, the screw rod can abut against the sliding rod through the abutment block, thereby providing a protective effect on the end of the screw rod.

[0014] Optionally, a through hole is formed at one end of the screw rod away from the sliding rod, a driving rod is slidably connected in the through hole, and the driving rod is bent into a right angle.

[0015] By adopting the above technical solution, the driving rod can be held by hand to drive the screw rod to rotate, thereby making it more convenient and labor-saving to rotate the screw rod.

[0016] Optionally, the end of the driving rod is fixedly connected to a limiting nut, and the diameter of the limiting nut is larger than the diameter of the through hole.

[0017] By adopting the above technical solution, the position of the driving rod can be limited by the limit nut, thereby reducing the occurrence of the driving rod slipping out of the through hole.

[0018] Optionally, the fixing assembly includes two fixing rods, the two fixing rods are located at the same end of the first mounting plate, the fixing rods are arranged in a right angle shape and one end of the fixing rod is fixed to the first mounting plate.

[0019] By adopting the above technical solution, holes for the two fixing rods to pass through are punched on the sewing machine, thereby the fixing rods can be inserted into the holes and the positions of the fixing rods in the holes can be limited by the right-angled fixing rods, thereby preliminarily fixing the entire first mounting plate to the sewing machine, thereby facilitating the adjustment of the screw.

[0020] Optionally, the fixing assembly further includes a limiting rod, and the limiting rod is located at an end of the first mounting plate away from the fixing rod.

[0021] By adopting the above technical solution, a hole is punched on the sewing machine for the limit rod to pass through. After the first mounting plate is initially fixed by the fixing rod, the other end of the second mounting plate can be inserted into the punched hole through the limit rod, thereby fixing the entire first mounting plate on the sewing machine and allowing it to be removed at any time.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. The screw can push the slide rod to move, and then the slide rod drives the pulley mounting seat to move on the sewing machine. Thus, a single person can tighten the belt with less force, which improves the convenience of tightening the pulley and saves manpower;

[0024] 2. The triangle iron can be used to abut against the pulley mounting seat, thereby increasing the abutment area between the slide bar and the pulley mounting seat, thereby facilitating the movement of the pulley mounting seat;

[0025] 3. The driving rod can be held by hand to drive the screw to rotate, thereby making it more convenient and labor-saving to rotate the screw. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1 -Attached Figure 3 , further details of this application are given.

[0031] The embodiment of the present application is: a sewing machine conveyor belt pulley auxiliary installation mechanism, referring to Figure 1 and Figure 2, comprising a first mounting plate 1 provided on the sewing machine, the first mounting plate 1 being placed below the pulley mounting seat. Second mounting plates 2 are fixedly connected to the upper and lower sides of the mounting plate, and the cross-section of the second mounting plates 2 combined is configured to be gate-shaped. Both second mounting plates 2 are provided with sliding holes 21, which are arranged along the length of the second mounting plates 2. A common sliding rod 3 is inserted into and slidably connected to the two sliding holes 21, and the length of the sliding rod 3 is perpendicular to the length of the first mounting plate 1. The upper end of the sliding rod 3 is placed outside the sliding hole 21 and fixedly connected to a triangular reinforcement plate 61.

[0032] A threaded tube 10 is fixedly connected to the side of the first mounting plate 1 facing away from the sewing machine. The axis of the threaded tube 10 is parallel to the length of the first mounting plate 1. A screw rod 4 is internally threadedly connected to the threaded tube 10, with the axis of the screw rod 4 coinciding with the axis of the threaded tube 10. An abutment block 7 is fixedly connected to the end of the threaded rod near the slide rod 3. The screw rod 4 abuts the slide rod 3 via the abutment block 7.

[0033] By rotating the screw rod 4, the screw rod 4 can move toward the side of the slide rod 3 along the axial direction of the threaded tube 10, and drive the slide rod 3 to move, so that the slide rod 3 applies external force to the pulley mounting seat through the angle iron, thereby tightening the belt.

[0034] To facilitate the rotation of the screw rod 4, a through hole 41 is formed at the end of the screw rod 4 away from the slide rod 3. A drive rod 9 is slidably connected to the through hole 41. The drive rod 9 is bent at a right angle. To prevent the drive rod 9 from slipping out of the through hole 41, a limit nut 8 is fixedly connected to one end of the drive rod 9. The diameter of the limit nut 8 is larger than that of the through hole 41.

[0035] Thus, external force is applied to the driving rod 9, so that the driving rod 9 can drive the screw rod 4 to rotate. The end of the first mounting plate 1 facing away from the threaded tube 10 is provided with a fixing assembly 5 for fixing the first mounting plate 1 on the sewing machine.

[0036] Reference Figure 2 and Figure 3 The fixing assembly 5 includes two fixing rods 51 and a limiting rod 52. The two fixing rods 51 are located at the same end of the first mounting plate 1, and the limiting rod 52 is located at the end of the first mounting plate 1 away from the fixing rod 51. The fixing rod 51 is arranged at a right angle, one end of the fixing rod 51 is fixedly connected to the first mounting plate 1, and one end of the limiting rod 52 is fixedly connected to the first mounting plate 1, and the bending direction of the fixing rod 51 is parallel to the length direction of the first mounting plate 1, and the bending direction of the limiting rod 52 is perpendicular to the length direction of the first mounting plate 1.

[0037] Therefore, the sewing machine can be provided with holes for the two fixing rods 51 to pass through and a hole for the limiting rod 52 to pass through in advance. The fixing rods 51 are then inserted into the holes to preliminarily fix the entire first mounting plate 1 to the sewing machine. Then, the other end of the second mounting plate 2 is inserted into the prepared holes through the limiting rod 52 to fix the entire first mounting plate 1 to the sewing machine.

[0038] The implementation principle of the embodiment of the present application is: when the belt on the sewing machine is tensioned, the first mounting plate 1 can be fixed to the sewing machine through the fixing component 5, so that the slide rod 3 and the triangle iron 6 are in contact with the pulley mounting seat, and then the screw rod 4 is rotated by the driving rod 9, so that the screw rod 4 moves along the axial direction of the threaded tube in the threaded tube 10, so that the slide rod 3 applies external force to the pulley mounting seat through the angle iron, thereby tensioning the belt.

[0039] The examples of this specific embodiment are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
