Technical Field

[0001] The utility model belongs to the technical field related to sewing machines, in particular to a roller machine. Background Art

[0002] At present, the existing roller carriage feeds materials by a single-side roller, and the operator needs to manually control the feeding track of the thick material when the roller carriage is working. Therefore, when the roller carriage is used in combination with a sleeve sewing machine, since the sleeve sewing machine is mainly used for fabrics such as suits and jackets, the fabrics are relatively soft and difficult to control the feeding track, which makes the existing roller carriage unable to be used as a mother machine and converted into a sleeve sewing machine. Utility Model Content

[0003] In view of this, it is necessary to provide a roller car for solving the above-mentioned technical problems.

[0004] A roller car, the roller car comprising:

[0005] The roller car body includes a machine needle and a feeding roller, wherein the feeding roller is arranged on one side of the machine needle in the radial direction and is used to transfer the fabric to the machine needle;

[0006] An auxiliary feeding mechanism is installed on the roller car body, and the auxiliary feeding mechanism includes a feeding assembly. Along the movement trajectory of the fabric, the feeding assembly is arranged on the side of the needle away from the feeding roller, and the feeding assembly can transmit the fabric passing through the needle to the outside.

[0007] It can be understood that the fabric passing through the needles on the roller car main machine is delivered by a feeding assembly. In this way, the feeding trajectory of the fabric processed by the needles can be controlled, and the automatic control of the feeding trajectory when the roller car is working can be realized, so that the roller car can be used as a mother machine and converted into a sleeve sewing machine.

[0008] In one of the embodiments, the feeding assembly is configured as a synchronous belt assembly;

[0009] The synchronous belt assembly includes a synchronous belt, and the synchronous belt can contact the fabric downward to drive the fabric to move.

[0010] It can be understood that the fabric is conveyed by the contact between the synchronous belt and the fabric, which can increase the contact area of ​​the feeding component when conveying the fabric, thus improving the stability of the feeding component during the feeding process.

[0011] In one embodiment, the auxiliary feeding mechanism further comprises a motor, and the rotating shaft of the motor is drivingly connected to the synchronous belt assembly;

[0012] Wherein, the rotation speed of the rotating shaft can be adjusted.

[0013] It can be understood that by adjusting the rotation speed of the shaft on the motor, the transmission speed of the synchronous belt when conveying the fabric can be adjusted, and the synchronous belt can be synchronized with the feeding roller on the roller car body to convey the fabric; in this way, the auxiliary feeding mechanism can be suitable for conveying fabrics with different transmission speeds.

[0014] In one of the embodiments, the auxiliary feeding mechanism further comprises a mounting plate, and the synchronous belt assembly is mounted on the mounting plate;

[0015] Wherein, the mounting plate is rotatably connected to the roller car body, and the synchronous belt assembly can swing relative to the roller car body driven by the mounting plate, so as to control the pressing force of the synchronous belt on the fabric.

[0016] It can be understood that by using the mounting plate to drive the synchronous belt assembly to swing, the pressing force of the synchronous belt on the fabric during transmission can be adjusted, so that the auxiliary feeding mechanism can be used to transmit different fabrics.

[0017] In one embodiment, the auxiliary feeding mechanism further includes a tension spring fixing plate, a tension spring and a tension spring adjusting plate, and the tension spring fixing plate and the tension spring adjusting plate are connected in transmission via the tension spring;

[0018] Wherein, the tension spring fixing plate is connected to the roller car body, the tension spring adjusting plate is connected to the mounting plate, and the mounting position of the tension spring adjusting plate on the mounting plate can be adjusted.

[0019] In one of the embodiments, the roller car body also includes a pressure rod, which is respectively connected to the feed roller and the mounting plate in a transmission manner, and the feed roller and the mounting plate can be lifted or pressed down at the same time under the drive of the pressure rod.

[0020] It is understandable that the mounting plate can be lifted or pressed down together with the feed roller under the drive of the pressure rod, so that the setting of the auxiliary feeding mechanism will not affect the material laying of the original feed roller and play a role in auxiliary material pressing.

[0021] In one embodiment, the auxiliary feeding mechanism further includes a rotating connection block and a connection seat, wherein the rotating connection block is fixedly connected to the mounting plate and is rotatably connected to the connection seat;

[0022] Wherein, the connecting seat is fixedly connected to the roller car body and is used to carry the mounting plate.

[0023] In one of the embodiments, the installation position of the connecting seat on the roller vehicle body can be adjusted.

[0024] It can be understood that by adjusting the installation position of the connecting seat on the roller car body, the distance between the synchronous belt and the needle can be adjusted, so as to ensure that the synchronous belt can transmit the fabric processed by the needle to the outside.

[0025] In one of the embodiments, the auxiliary feeding mechanism further includes a tensioning wheel assembly, wherein the tensioning wheel assembly includes a tensioning wheel, and the wheel surface of the tensioning wheel can press the synchronous belt downward to adjust the tension of the synchronous belt;

[0026] Wherein, the mounting position of the tension wheel assembly on the mounting plate can be adjusted.

[0027] It is understandable that the tensioning wheel assembly is used to adjust the tension of the synchronous belt, so that the transmission of the fabric by the synchronous belt can be ensured.

[0028] In one of the embodiments, the auxiliary feeding mechanism further includes a limit plate, which is disposed on the side of the synchronous belt facing the needle and connected to the mounting plate, and is used to limit the synchronous belt to the mounting plate.

[0029] It can be understood that the synchronous belt is limited to the mounting plate by a limiting plate, so that the synchronous belt can be prevented from detaching from the mounting plate, thereby ensuring the stability of the synchronous belt when conveying the fabric.

[0030] Due to the application of the above technical solution, the utility model has the following advantages compared with the prior art:

[0031] The roller car for which protection is sought in the utility model uses a feeding assembly to feed the fabrics passing through the needles on the main machine of the roller car.

[0041] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0042] The roller car 100 for which protection is sought in the present application is used in combination with a sleeve sewing machine (not shown) to automatically control the feeding trajectory of the fabric (not shown).

[0043] like Figures 1 to 4 As shown, the roller car 100 provided in one embodiment of the present application includes a roller car body 10 and an auxiliary feeding mechanism 20. The roller car body 10 includes a needle 11 and a feeding roller 12. The feeding roller 12 is arranged on one side of the needle 11 in the radial direction, and is used to transfer the fabric to the needle 11. The auxiliary feeding mechanism 20 is installed on the roller car body 10. The auxiliary feeding mechanism 20 includes a feeding assembly 21. Along the movement trajectory of the fabric, the feeding assembly 21 is arranged on the side of the needle 11 away from the feeding roller 12, and the feeding assembly 21 can transfer the fabric passing through the needle 11 to the outside. In other words, the roller car 100 uses the feeding assembly 21 to transfer the fabric passing through the needle 11 on the roller car body 10 to the outside. In this way, the feeding trajectory of the fabric processed by the needle 11 can be controlled, and the automatic control of the feeding trajectory when the roller car 100 is working can be realized, so that the roller car 100 can be used as a mother machine and converted into a sleeve sewing machine.

[0044] It should be noted that the specific structure of the above-mentioned feeding roller 12 and the working principle of how to transfer the fabric to the machine needle 11 during operation can all adopt the conventional method on the existing roller cart; in addition, for technical personnel in this field, the roller cart 100 of the present application can specifically add an auxiliary feeding mechanism 20 on the basis of the original roller cart, that is, the roller cart 100 of the present application can be improved on the basis of the original roller cart structure, which has the effect of reducing costs, and will not be elaborated here.

[0045] like Figure 4 As shown, in some embodiments, the feeding assembly 21 is configured as a synchronous belt assembly 211, and the synchronous belt assembly 211 includes a synchronous belt 2111, which can contact the fabric downward to drive the fabric to move and realize the transmission of the fabric in the transmission direction of the synchronous belt 2111.

[0046] It can be understood that the contact between the synchronous belt 2111 and the fabric is used to realize the transmission of the fabric, which can increase the contact area of ​​the feeding component 21 when transmitting the fabric, so that the stability of the feeding component 21 during the feeding process can be improved. Of course, for those skilled in the art, the feeding component 21 can also be set as a transmission roller component, which will not be elaborated here.

[0047] like Figure 4As shown, in some embodiments, the auxiliary feeding mechanism 20 also includes a motor 22, and the rotating shaft 221 of the motor 22 is connected to the synchronous belt assembly 211 in a transmission manner; wherein, the rotation speed of the rotating shaft 221 can be adjusted, so that when the auxiliary feeding mechanism 20 is working, the transmission speed of the synchronous belt 2111 when transmitting the fabric can be adjusted, and the synchronous belt 2111 can be synchronously transmitted with the feeding roller 12 on the roller car body 10 to transmit the fabric; in this way, the auxiliary feeding mechanism 20 can be suitable for transmitting fabrics with different transmission speeds. It should be noted that the rotating shaft 221 of the motor 22 is specifically circumferentially limited with the driving wheel 2112 on the synchronous belt assembly 211, so that when the motor 22 is working, the driving of the rotating shaft 221 can realize the driving of the driving wheel 2112 to rotate, and achieve the purpose of controlling the synchronous belt 2111 to transmit the fabric.

[0048] like Figure 4 As shown, in some embodiments, the auxiliary feeding mechanism 20 also includes a mounting plate 23, and the synchronous belt assembly 211 is mounted on the mounting plate 23. Of course, the motor 22 can also be mounted on the mounting plate 23; wherein the mounting plate 23 is rotatably connected to the roller car body 10, and the synchronous belt assembly 211 can swing relative to the roller car body 10 under the drive of the mounting plate 23, so as to control the pressing force of the synchronous belt 2111 on the fabric. In this way, the auxiliary feeding mechanism 20 can be used to convey different fabrics. It should be noted that the different pressures of the synchronous belt 2111 pressed against the fabric can adjust the static friction between the synchronous belt 2111 and the fabric when they are in contact. In this way, on the basis of ensuring that the synchronous belt 2111 can drive and convey the fabric, the synchronous belt 2111 can be used to convey fabrics with different friction coefficients, that is, to convey different fabrics.

[0049] In this embodiment, the auxiliary feeding mechanism 20 also includes a tensioning wheel assembly 231, which includes a tensioning wheel 2311. The wheel surface of the tensioning wheel 2311 can press the synchronous belt 2111 downward to adjust the tension of the synchronous belt 2111. The mounting position of the tensioning wheel assembly 231 on the mounting plate 23 can be adjusted, so that the synchronous belt 2111 can ensure the transmission of the fabric. It should be noted that the other structural components of the tensioning wheel assembly 231 and how to adjust the tension of the synchronous belt 2111 during operation can all adopt existing conventional methods, which will not be elaborated here.

[0050] In addition, the auxiliary feeding mechanism 20 of this embodiment further includes a limiting plate 232, which is disposed on the side of the synchronous belt 2111 facing the needle 11 and connected to the mounting plate 23, and is used to limit the synchronous belt 2111 to the mounting plate 23. In this way, the synchronous belt 2111 can be prevented from being disengaged from the mounting plate 23, thus ensuring the stability of the synchronous belt 2111 when conveying the fabric.

[0051] like Figure 4 As shown, in this embodiment, the auxiliary feeding mechanism 20 further includes a rotating connection block 24 and a connection seat 25, wherein the rotating connection block 24 is fixedly connected to the mounting plate 23 and is rotatably connected to the connection seat 25, wherein the connection seat 25 is fixedly connected to the roller vehicle body 10, and is used to carry the mounting plate 23. In other words, the connection seat 25 of this embodiment serves as a bearing component of the overall mechanism of the auxiliary feeding mechanism 20.

[0052] like Figure 5 As shown, exemplarily, the rotating connecting block 24 includes a fixed plate portion 241 and a connecting shaft portion 242, the fixed plate portion 241 is abutted against the mounting plate 23, and is fixed to the mounting plate 23 by a first bolt 201 passing through the fixed plate portion 241, the connecting shaft portion 242 is rotatably connected to the connecting seat 25 by a bearing 251, and the connecting shaft portion 242 can pass through the connecting seat 25, and is axially limited by a retaining ring 252, so that the mounting plate 23 can rotate relative to the roller car body 10 with the connecting shaft portion 242 as the rotation center.

[0053] In some embodiments, the installation position of the connecting seat 25 on the roller cart body 10 can be adjusted, so that the installation position of the mounting plate 23 on the roller cart body 10 can be adjusted, and then the distance between the synchronous belt 2111 and the needle 11 can be adjusted. In this way, it can be ensured that the synchronous belt 2111 can transmit the fabric processed by the needle 11 to the outside.

[0054] Exemplarily, a first waist-shaped hole 253 is provided on the connecting seat 25, and the connecting seat 25 can be fixed to the roller car body 10 by a second bolt 202 passing through the first waist-shaped hole 253. In this way, the structural characteristics of the first waist-shaped hole 253 can be utilized to realize the position of the connecting seat 25 relative to the second bolt 202, that is, the installation position of the connecting seat 25 on the roller car body 10 can be adjusted.

[0055] like Figure 4 As shown, in some embodiments, the auxiliary feeding mechanism 20 further includes a tension spring fixing plate 26, a tension spring 27 and a tension spring adjusting plate 28, and the tension spring fixing plate 26 and the tension spring adjusting plate 28 are connected to each other by means of the tension spring 27; wherein, the tension spring fixing plate 26 is connected to the roller car body 10, and the tension spring adjusting plate 28 is connected to the mounting plate 23, and specifically, the tension spring adjusting plate 28 can be connected to the fixing plate portion 241 of the rotating connecting block 24, and the mounting position of the tension spring adjusting plate 28 on the mounting plate 23 can be adjusted. In other words, the auxiliary feeding mechanism 20 of this embodiment can adjust the pulling of the tension spring 27 on the mounting plate 23 by adjusting the mounting position of the tension spring adjusting plate 28 on the mounting plate 23, so that the mounting plate 23 can drive the synchronous belt assembly 211 to rotate relative to the connecting seat 25, and adjust the pressing force of the synchronous belt 2111 on the fabric.

[0056] In this embodiment, a second waist-shaped hole 281 is formed on the tension spring adjustment plate 28 , and the tension spring adjustment plate 28 can be fixed to the fixing plate portion 241 of the rotating connection block 24 by a third bolt 203 passing through the second waist-shaped hole 281 .

[0057] like Figure 2 , Figure 4 As shown, in some embodiments, the roller car body 10 further includes a pressing rod 13, which is in transmission connection with the feeding roller 12 and the mounting plate 23, and the feeding roller 12 and the mounting plate 23 can be lifted or pressed down at the same time under the driving of the pressing rod 13. In this way, the setting of the auxiliary feeding mechanism 20 will not affect the material laying of the original feeding roller 12, and can play the role of auxiliary material pressing.

[0058] like Figure 4 As shown, for example, one end of the mounting plate 23 facing the needle 11 can be connected and fixed to the pressure rod 13 by a pressure rod connecting block 131. Since the mounting plate 23 is rotatably mounted on the connecting seat 25 by a rotating connecting block 24, when the pressure rod 13 moves up and down, the mounting plate 23 can drive the synchronous belt assembly 211 to be lifted or lowered. In addition, the transmission connection between the pressure rod 13 and the feeding roller 12 can adopt the conventional method of the existing roller cart, which will not be elaborated here.

[0059] In summary, the roller cart 100 of the present application uses the structural setting of the auxiliary feeding mechanism 20, so that the roller cart 100 can control the feeding trajectory of the fabric processed by the machine needle 11 when it is working, and realize the automatic control of the feeding trajectory of the roller cart 100 when it is working. In this process, the conveyed fabric can be auxiliary pressed, and the synchronous belt 2111 can adjust the conveying speed and pressing force of the fabric separately, so that the feeding trajectory of the fabric can be adjusted as needed.

[0060] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
