[0031] Reference Figure 1 , Figure 2 and Figure 4 The utility model proposes a hemming machine for cloth processing, comprising: a base 1, on which a driving member 2 is arranged; a pushing mechanism 3, comprising a first transmission wheel 31, a roller assembly, a pushing belt 33 and an electric cylinder 34, wherein the first transmission wheel 31 is drivingly connected to the output shaft of the driving member 2, the pushing belt 33 is sleeved on the first end of the roller assembly and the outer side of the first transmission wheel 31 to form a pushing pressing surface 13, the output shaft of the electric cylinder 34 is connected to the second end of the roller assembly, and the electric cylinder 34 is used to drive the roller assembly to swing around the rotation point in the middle thereof to adjust the distance between the pushing pressing surface 13 and the base 1.

[0032] In the above embodiment, the base 1 provides a stable support foundation for the entire hemming machine, ensuring the stability of the hemming machine when working. The pushing mechanism 3 includes a first transmission wheel 31, a roller assembly, a pushing belt 33 and an electric cylinder 34. The driving member 2 is a motor. The output end of the motor is connected to the first transmission wheel 31. The first transmission wheel 31 is driven by the motor to rotate, and the first transmission wheel 31 drives the pushing belt 33 to move, thereby driving the cloth to move forward. The first end of the roller assembly is in close contact with the pushing belt 33, and the bottom of the pushing belt 33 forms a pushing pressing surface 13. The output end of the electric cylinder 34 is connected to the roller assembly. The electric cylinder 34 is used to adjust the swing of the roller assembly, thereby changing the position of the pushing pressing surface 13, so that the pushing pressing surface 13 is adapted to cloths of different thicknesses. When the fabric is thicker, the output end of the electric cylinder 34 makes corresponding adjustments, driving the roller assembly to move upward, thereby driving the push belt 33 to move upward, and the gap between the push pressing surface 13 and the base 1 becomes larger, so that the fabric can pass through the push pressing surface 13 smoothly. On the contrary, when the fabric is thinner, the output end of the electric cylinder 34 drives the roller assembly to move downward, and the gap between the push pressing surface 13 and the base 1 becomes smaller, thereby ensuring that the fabric can move forward evenly and stably. Through the push pressing surface 13, the hemming machine can adapt to fabrics of different thicknesses, and there is no need to make complex adjustments or reconfigure the hemming machine when changing fabrics, thereby improving the applicability and flexibility of the hemming machine. The push pressing surface 13 is in direct contact with the fabric, and the push pressing surface 13 ensures that no matter how the thickness of the fabric changes, it can be pushed evenly and stably, thereby avoiding problems such as uneven hemming caused by changes in fabric thickness.

[0033] In one embodiment, reference Figure 2 and Figure 3 , further comprising a case 4, the case 4 being arranged on the base 1, and the driving member 2 being arranged in the case 4. A hemming assembly 5 for sewing hemming of fabric is also provided, the hemming assembly 5 comprising a sewing needle 51, a push rod 52, a compression spring 53 and a cam 54, the cam 54 being connected to the output end of the driving member 2, the push rod 52 being arranged below the cam 54 and connected to the cam 54, the compression spring 53 being sleeved on the push rod 52, and the two ends of the compression spring 53 being respectively fixedly connected to the case 4 and the top end of the push rod 52, and the sewing needle 51 being arranged at the bottom end of the push rod 52.

[0034] In the above embodiment, the chassis 4 is arranged on the base 1, and the edge binding assembly 5 is connected to the output end of the driving member 2, realizing the transmission of power, so that it can perform stitching and edge binding on the cloth and complete the edge binding operation of the cloth. The pushing mechanism 3 is also connected to the output end of the driving member 2, ensuring that when the edge binding assembly 5 performs stitching operation, the pushing mechanism 3 can synchronously press and push the cloth, so that the cloth can move forward evenly and stably, and the edge binding quality is improved. The pushing mechanism 3 is preferably arranged as a group of two, which are arranged one before and one after the edge binding assembly 5, so that the cloth can be pushed and pulled during the edge binding operation, so that the edge binding operation can achieve better results.

[0035] The sewing needle 51 is a working part in the hemming assembly 5, which is responsible for passing the thread through the cloth for hemming and sewing. The cam 54 is directly connected to the output end of the driving member 2, and the push rod 52 is connected to the bottom of the cam 54, and moves up and down with the rotation of the cam 54. The compression spring 53 is sleeved on the push rod 52, and its two ends are respectively fixedly connected to the chassis 4 and the top of the push rod 52, that is, the bottom end of the compression spring 53 is mounted on the upper end of the chassis 4 to support the push rod 52, providing a certain elasticity and buffering effect for the push rod 52, ensuring that the sewing needle 51 can stably and accurately complete the sewing action during the operation, and complete the needle threading and resetting of each cycle, ensuring the flexibility of the sewing needle 51, and preventing damage or errors caused by excessive impact. When the driving member 2 drives the cam 54 to rotate, the cam 54 pushes the push rod 52 to move downward, thereby driving the sewing needle 51 to sew the cloth. Due to the joint action of the push rod 52 and the compression spring 53, the sewing needle 51 can maintain a stable pressure and depth during the sewing process, and achieve a high-quality hemming effect. The hemming assembly 5 has a simple structure and is easy to operate, and is suitable for processing various fabrics, thereby improving the practicability and versatility of the hemming machine.

[0036] In addition, the design of the driving member 2 enables the hemming assembly 5 and the pushing mechanism 3 to move synchronously, ensuring the coordination of the hemming and pushing movements, and further improving the quality and efficiency of the hemming. This synchronous design reduces errors and defective products caused by uncoordinated movements, and improves the stability and reliability of the entire hemming process.

[0037] In one embodiment, reference Figure 4The pushing mechanism 3 also includes a transmission rod 35, a support seat 36, a second transmission wheel 37, a support rod 39 and an adjustment frame 30. The roller assembly includes a roller 32 and a rolling bracket 38. The support seat 36 is arranged on the base 1. The transmission rod 35 is penetrated by the support seat 36. The second transmission wheel 37 and the first transmission wheel 31 are respectively arranged at both ends of the transmission rod 35. The second transmission wheel 37 is transmission-connected to the output end of the driving member 2. The adjustment frame 30 is arranged at the output end of the electric cylinder 34. An adjustment hole is opened on the support rod 39. The support rod 39 is slidingly connected to the adjustment frame 30 through the adjustment hole. The bottom end of the support rod 39 is fixedly connected to the rolling bracket 38, and the roller 32 is arranged in the rolling bracket 38.

[0038] In the above embodiment, the support seat 36 is fixedly arranged on the base 1 for the transmission rod 35 to pass through and support it. The transmission rod 35, as the main transmission component of the pusher mechanism 3, is arranged on the support seat 36 and connected to the output end of the driving member 2 to realize the transmission of power. The second transmission wheel 37 and the first transmission wheel 31 are respectively arranged at the two ends of the transmission rod 35, wherein the second transmission wheel 37 is directly connected to the output end of the driving member 2, receives the power from the driving member 2, and drives the entire pusher mechanism 3 to work. The support rod 39 is connected to the support seat 36 by rotation, providing stable support for the roller 32 and the rolling bracket 38. The roller 32 is arranged in the rolling bracket 38 and can rotate freely with the rotation of the support rod 39. The pusher belt 33 is sleeved on the outer side of the roller 32 and the first transmission wheel 31, and forms a push pressing surface 13. The outer side of the pusher belt 33 can also be set to a friction surface. When pushing the cloth, it is not easy to slip under the action of high friction. When the driving member 2 drives the transmission rod 35 to rotate, the second transmission wheel 37 drives the transmission rod 35 and the first transmission wheel 31 to rotate synchronously, thereby driving the push belt 33 and the roller 32 to move. Since the push belt 33 forms a push-pressing surface 13, it can directly contact the cloth and provide stable pressure and friction during the pushing process of the cloth, so that the cloth can move forward evenly and stably, ensuring the stability and continuity of the cloth during the hemming process, and improving the quality and efficiency of the hemming. At the same time, the structure of the push mechanism 3 is simple and compact, easy to install and maintain, and reduces the cost of use and maintenance. In addition, since the support rod 39 rotates, it can drive the roller 32 to adjust its position, realize the height adjustment of the push-pressing surface 13, adapt to cloths of different thicknesses, and improve the flexibility and applicability of the hemming machine.

[0039] As a driving element with the function of accurately controlling the extension and contraction amount, the electric cylinder 34 is preferably arranged on the support seat 36, with the driving end facing the base 1, providing power for the adjustment frame 30 to adjust the height of the push mechanism 3. The adjustment frame 30 is connected to the output end of the electric cylinder 34 and can move with the extension and contraction of the electric cylinder 34. An adjustment hole is provided on the support rod 39, and the adjustment frame 30 can be inserted into the adjustment hole. The adjustment frame 30 is slidably connected with the support rod 39 through the adjustment hole, so that the adjustment frame 30 can drive the support rod 39 to move up and down. The position of the roller 32 and the push-pressing surface 13 can be accurately adjusted by the extension and contraction of the electric cylinder 34 to adapt to different fabric thicknesses and hemming requirements. Specifically, for example, the electric cylinder 34 drives the adjustment frame 30 to rise, the support frame will rotate around the pin 6 as the center, and the roller 32 will descend, thereby achieving height adjustment. Through the precise control of the electric cylinder 34, the position of the roller 32 can be fine-tuned, so that the push-pressing surface 13 always maintains the best contact state with the fabric, thereby improving the accuracy and stability of the hemming operation. At the same time, this adjustment method is simple and convenient to operate, which improves the usability and flexibility of the hemming machine.

[0040] In one embodiment, a pin shaft 6 is further included, which is passed through the support rod 39, and the pin shaft 6 is fixedly connected to the support seat 36, and the support rod 39 is rotatably connected to the support seat 36 through the pin shaft 6. A support spring 7 is also included, and the support rod 39 is a telescopic rod, and the support spring 7 is sleeved in the support rod 39, and the support spring 7 is arranged between the rolling bracket 38 and the pin shaft 6.

[0041] In the above embodiment, the pin 6 passes through the support rod 39 and is fixedly connected to the support seat 36, which plays a role in limiting the support rod 39, so that the support rod 39 can rotate with the pin 6 as the rotating shaft, ensuring the stability and reliability of the support rod 39 during the rotation process. The support rod 39 adopts a telescopic rod structure, which can passively adjust the length according to the pushing situation to meet the pushing requirements of different cloth thicknesses. The support spring 7 is sleeved in the support rod 39, one end of which is connected to the rolling bracket 38, and the other end is supported and limited by the pin 6, which plays a role of buffering and passive adjustment. When the roller 32 pushes the cloth, the support spring 7 can be extended and retracted according to the thickness and pressure changes of the cloth, providing appropriate buffering and supporting force, so that the pushing and pressing surface 13 can always maintain close contact with the cloth, and realize the stable pushing of the cloth. At the same time, the buffering effect of the support spring 7 can also reduce the deformation or damage of the cloth caused by excessive pushing force, and improve the quality and efficiency of the hemming operation. This design enables the hemming machine to adapt to cloths of different thicknesses, and improves the versatility and flexibility of the hemming machine.

[0042] In one embodiment, it also includes a driving shaft 8, a driving wheel 9 and a driving belt 10, wherein the driving shaft 8 is connected to the output end of the driving member 2, the driving wheel 9 is arranged on the driving shaft 8, and the driving belt 10 is sleeved on the outer side of the driving wheel 9 and the second transmission wheel 37.

[0043] In the above embodiment, in order to further improve the output and transmission of power, the drive shaft 8 is connected to the output end of the drive member 2 as a key component of power transmission, the cam 54 is connected to the end of the drive shaft 8, and the drive wheel 9 is set at a suitable position in the middle of the drive shaft 8, and rotates with the rotation of the drive shaft 8. The drive belt 10 is sleeved on the outside of the drive wheel 9 and the second transmission wheel 37 to form a power transmission path. When the drive member 2 is started, the drive shaft 8 drives the drive wheel 9 to rotate, and then transmits the power to the second transmission wheel 37 through the drive belt 10, thereby driving the pusher mechanism 3 to work. The transmission method has a simple and reliable structure, and can effectively transmit the power of the drive member 2 to the pusher mechanism 3 to achieve the normal operation of the hemming machine. At the same time, by adjusting the tension and position of the drive belt 10, the stability and efficiency of power transmission can be ensured, and the performance of the hemming machine can be further improved. In addition, since the drive wheel 9 and the cam 54 are both set on the drive shaft 8, the synchronization of high hemming and pushing can be guaranteed, and the structure of the entire hemming machine can be made more compact, reducing space occupation, and improving the overall aesthetics and practicality of the equipment.

[0044] In one embodiment, a fixing frame 11 for limiting and supporting the driving shaft 8 is further included, which is disposed on one side of the cam 54 and sleeved on the driving shaft 8 .

[0045] In the above embodiment, the fixing frame 11 is provided on the side of the cam 54 as a supporting and limiting component of the drive shaft 8, but does not contact the cam 54, and is sleeved on the drive shaft 8. Since the drive shaft 8 may be relatively long, the fixing frame 11 can effectively support the drive shaft 8 to ensure the stability and reliability of the drive shaft 8 during operation. At the same time, the fixing frame 11 can also limit the drive shaft 8 to prevent it from shifting or shaking during operation, thereby ensuring the accurate connection and power transmission between the drive shaft 8 and the driving member 2 and the pushing mechanism 3, which can not only improve the overall stability of the hemming machine, but also extend the service life of the drive shaft 8 and reduce the maintenance cost of the equipment.

[0046] In one embodiment, an anti-slip pad 12 is further included, which is fixedly disposed on the base 1 and is located below the edging assembly 5 .

[0047] In the above embodiment, the anti-skid pad 12, as a component for enhancing friction, is fixed on the base 1 and is located below the hemming assembly 5, so that the fabric will not slip when the sewing needle 51 is penetrating. At the same time, the material and structural design of the anti-skid pad 12 also have a certain elasticity and buffering effect, which can absorb and reduce vibration and impact to a certain extent, further ensuring the stability during the hemming operation, thereby ensuring that the hemming effect is more ideal.

[0048] In one embodiment, the base 1 is provided with an avoidance hole for the sewing needle 51 to pass through.

[0049] In the above embodiment, the avoidance hole is provided on the base 1 so that the sewing needle 51 can smoothly pass through the base 1 to sew the fabric. The position and size of the avoidance hole need to be designed to ensure that the sewing needle 51 can pass through accurately while avoiding interference or collision with other components on the base 1. By providing the avoidance hole, the smoothness and stability of the sewing needle 51 during the sewing process can be ensured, and the efficiency and quality of the hemming operation can be improved. In addition, the design of the avoidance hole also takes into account the overall compactness and aesthetics of the hemming machine, making the entire device more practical and beautiful.
