Description

Technical Field

[0001] This utility model relates to the field of sewing machine equipment technology, specifically a novel eccentric wheel for a pleating machine. Background Technology

[0002] With its high precision, high efficiency, and diverse pleating capabilities, the pleating machine has become a key piece of equipment in modern garment manufacturing and home textile production, especially suitable for design scenarios that pursue refinement and creativity.

[0003] Currently, the existing eccentric wheels in pleating machines have low transmission efficiency due to their single eccentric wheel structure, and lack stabilization mechanisms, which makes the sewing machine prone to material slippage during operation. Utility Model Content

[0004] To address the issues of low efficiency and instability in existing eccentric wheel transmissions, this invention provides a novel eccentric wheel for pleating machines.

[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0006] A novel eccentric wheel for a pleating machine includes a drive housing. A worm and a worm wheel are rotatably connected to the inner sides of the drive housing, respectively. The worm and worm wheel mesh with each other, and a drive shaft is fitted inside the worm wheel. A pair of eccentric wheel bodies are provided, with locking slots on adjacent sides of each pair of eccentric wheel bodies that engage with the drive shaft. Both ends of the drive shaft extend into the two locking slots and are fitted with retaining springs. Connecting rod assemblies are provided on both sides of the outer wall of each pair of eccentric wheel bodies.

[0007] Furthermore, the eccentric wheel body includes a main wheel, and the bayonet is formed at the center of the main wheel.

[0008] The beneficial effect of adopting the above-mentioned further solution is that it ensures that the drive shaft is accurately located at the center of the eccentric wheel body during installation, guarantees the balance of the eccentric wheel's rotation, and avoids vibration and wear caused by installation deviation. Furthermore, the main wheel has a recessed hole on the side away from the drive shaft, and a bearing is embedded inside the recessed hole. The main wheel is rotatably connected to the secondary wheel through the bearing.

[0009] The beneficial effect of adopting the above-mentioned further solution is that the bearing can effectively reduce the friction between the main wheel and the auxiliary wheel, reduce energy loss during operation, and make the eccentric wheel rotate more smoothly.

[0010] Furthermore, the two auxiliary wheels are centrally symmetrical about the drive housing and are located diagonally. The advantage of this further design is that it allows for more even force distribution on the eccentric wheel during rotation, effectively balancing the centrifugal force generated by the eccentric wheel's rotation, reducing vibration during operation, and lowering noise.

[0011] Furthermore, the connecting rod assembly includes a collar, and the collar is fitted onto the outer wall of the secondary wheel.

[0012] The beneficial effect of adopting the above-mentioned further solution is that it can be firmly connected to the auxiliary wheel, reliably transmit the rotational power of the auxiliary wheel to the rod, and ensure that the connecting rod assembly will not loosen or fall off during the power transmission process.

[0013] Furthermore, a rod is connected to the bottom end of the collar, and a through hole is provided on one side of the bottom end of the rod.

[0014] The advantage of adopting the above-mentioned further solution is that it facilitates connection with other sewing machine components. The rod can be connected to other transmission mechanisms or working parts of the sewing machine through bolts, pins and other connecting parts to achieve further transmission and distribution of power.

[0015] Furthermore, an input shaft is rotatably connected to the top surface of the drive housing, one end of which extends into the interior of the drive housing and is connected to one end of the worm gear.

[0016] The beneficial effect of adopting the above-mentioned further solution is that it provides a power input interface for the eccentric wheel system, which is convenient to connect to the power source of the sewing machine, and the rotational connection method allows the input shaft to flexibly transmit power to the worm gear, ensuring smooth power transmission.

[0017] Furthermore, a gap is provided between each of the pair of eccentric wheel bodies and the drive housing.

[0018] The beneficial effects of adopting the above-mentioned further solution are that it can avoid interference and friction between the eccentric wheel and the drive housing during rotation, prevent damage to components caused by mutual friction, and reserve space for the thermal expansion and contraction of the eccentric wheel, ensuring that the eccentric wheel can operate normally under different working conditions.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This new type of eccentric wheel in a pleating machine transmits power stably to the drive shaft through the meshing of a worm gear and worm wheel inside the drive housing. The drive shaft then engages with the two sets of eccentric wheel bodies via locking jaws and is secured by snap rings, driving the two sets of eccentric wheel bodies to rotate. Combined with the connecting rod assembly, the rotation of the eccentric wheels can be converted into the movement of other components, facilitating flexible power distribution and meeting the power needs of different working parts of the sewing machine. This allows the sewing machine to perform various sewing actions, achieving efficient power transmission. Furthermore, the rotation of the two eccentric wheels causes the fabric to lift up and then slowly lower down, greatly avoiding the material slippage problem of traditional sewing machines and ensuring stable operation.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5This utility model provides a technical solution: a novel eccentric wheel for a pleating machine, comprising a drive housing 100, with a worm 800 and a worm wheel 900 rotatably connected to both sides of the drive housing 100, the worm 800 and the worm wheel 900 meshing with each other, and a drive shaft 500 fitted inside the worm wheel 900; a pair of eccentric wheel bodies 200, each having a locking slot 700 on an adjacent side that engages with the drive shaft 500, both ends of the drive shaft 500 extending into the two locking slots 700 and fitted with retaining springs 600; and connecting rod assemblies 300 on both sides of the outer wall of the pair of eccentric wheel bodies 200, which connect the worm 800 and the worm wheel 900. The intermeshing mechanism stably transmits power to the drive shaft 500. The drive shaft 500 then engages with the two sets of eccentric wheel bodies 200 via the locking mechanism 700 and is secured by the retaining spring 600. This drives the two sets of eccentric wheel bodies 200 to rotate. Combined with the connecting rod assembly 300, the rotation of the eccentric wheels can be converted into the movement of other components, facilitating flexible power distribution and meeting the power requirements of different working parts of the sewing machine. This allows the sewing machine to perform various sewing actions, achieving efficient power transmission. Furthermore, the rotation of the two eccentric wheels causes the fabric to lift up and then slowly lower down, greatly avoiding the material slippage problem common in traditional sewing machines and ensuring stable operation.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] As an embodiment of this utility model, the eccentric wheel body 200 further includes a main wheel 2001. A bayonet 700 is formed at the center of the main wheel 2001 to ensure that the transmission shaft 500 is accurately positioned at the center of the eccentric wheel body 200 during installation, thus ensuring the balance of the eccentric wheel rotation and avoiding vibration and wear caused by installation deviation. The main wheel 2001 has a recessed hole 2002 on the side away from the transmission shaft 500. A bearing 2003 is embedded in the recessed hole 2002. The main wheel 2001 is rotatably connected to the auxiliary wheel 2004 through the bearing 2003. The bearing 2003 can effectively reduce the friction between the main wheel 2001 and the auxiliary wheel 2004, reduce energy loss during operation, and make the eccentric wheel rotate more smoothly. The two auxiliary wheels 2004 are centrally symmetrical about the drive housing 100 and are located diagonally, which can make the force on the eccentric wheel more uniform during rotation, effectively balance the centrifugal force generated by the rotation of the eccentric wheel, reduce vibration during the operation of the eccentric wheel, and reduce noise.

[0031] As an embodiment of this utility model, the connecting rod assembly 300 further includes a collar 3001. The collar 3001 is fitted onto the outer wall of the auxiliary wheel 2004, and can be firmly connected to the auxiliary wheel 2004, so as to reliably transmit the rotational power of the auxiliary wheel 2004 to the rod 3002, ensuring that the connecting rod assembly 300 will not loosen or fall off during the power transmission process. The bottom end of the collar 3001 is connected to the rod 3002. A through hole 3003 is opened on one side of the bottom end of the rod 3002, which facilitates the connection with other sewing machine parts. The rod 3002 can be connected to other transmission mechanisms or working parts of the sewing machine through bolts, pins and other connecting parts to realize further transmission and distribution of power.

[0032] As an embodiment of this utility model, the top surface of the drive housing 100 is rotatably connected to an input shaft 400. One end of the input shaft 400 extends into the interior of the drive housing 100 and is connected to one end of the worm gear 800, providing a power input interface for the eccentric wheel system. This facilitates connection to the power source of the sewing machine, and the rotatable connection allows the input shaft 400 to flexibly transmit power to the worm gear 800, ensuring smooth power transmission.

[0033] As an embodiment of this utility model, further, a gap is provided between the pair of eccentric wheel bodies 200 and the drive housing 100, which can prevent interference and friction between the eccentric wheel and the drive housing 100 during rotation, prevent damage to components caused by mutual friction, and reserve space for thermal expansion and contraction of the eccentric wheel to ensure that the eccentric wheel can operate normally under different working conditions.

[0034] Specifically, the working principle of this new type of eccentric wheel in a pleating machine is as follows: During use, the power source is connected to the input shaft 400. The rotation of the input shaft 400 drives the worm gear 800 inside the drive housing 100 to rotate. The worm gear 800 meshes with the worm wheel 900, transmitting power to the worm wheel 900, which in turn drives the transmission shaft 500, which is housed inside the worm wheel 900, to rotate. Both ends of the transmission shaft 500 are respectively engaged with the slots 700 at the center of the main wheel 2001 of a pair of eccentric wheel bodies 200, and are fixed by retaining springs 600, thereby driving the eccentric wheel bodies 200 to rotate. The main wheel 2001 is rotatably connected to the auxiliary wheel 2004 via a bearing 2003. The bearing 2003 reduces friction between the two, making rotation smoother. The two centrally symmetrical auxiliary wheels 2004, located diagonally, balance the centrifugal force generated by the rotation of the eccentric wheels, reducing vibration and noise. The collar 3001 on the outer wall of the auxiliary wheel 2004 transmits rotational power to the rod 3002. The rod 3002 is connected to other parts of the sewing machine through the perforation 3003 at the bottom, converting the rotation of the eccentric wheel into the movement of other parts, realizing the distribution of power, meeting the power needs of different working parts of the sewing machine, and enabling the sewing machine to complete a variety of sewing actions. This achieves efficient power transmission of the sewing machine. Furthermore, when the two eccentric wheels rotate, they can cause the fabric to lift up and then slowly fall down, effectively avoiding the problem of fabric slippage. Ultimately, this achieves efficient power transmission of the sewing machine and the completion of a variety of sewing actions.
