Abstract
Description
Technical Field
[0001] This utility model relates to the field of garment knitting equipment, and in particular to cantilever knitting machines. Background Technology
[0002] Current garment knitting equipment is widely used in the sewing production of various garments, boxes, backpacks, shoes and other fields.
[0003] Its existing equipment typically includes a cantilever and a working head. The cantilever can rotate relative to the worktable and drive the working head to the working position on the worktable, thereby processing the tooling on the worktable through the working head.
[0004] However, the rotating cantilever setup results in a dead zone in the machine head, meaning that the area under the cantilever cannot be processed. This also limits the processing range of the machine head. If the processing range needs to be increased, the length of the cantilever needs to be increased accordingly, which increases the overall footprint of the equipment and simultaneously increases the processing dead zone of the machine head. Utility Model Content
[0005] The purpose of this invention is to provide a cantilever fast hand that can increase the processing range without occupying additional equipment space, and can accurately control the working position at any position within the processing range.
[0006] To solve the above-mentioned technical problems, this utility model provides a cantilever fast hand, including a workbench and a cantilever mounted on the workbench. One end of the cantilever is connected to the workbench, and the other end is suspended above the workbench so that there is a clearance space between the end of the cantilever and the workbench. A first extension arm is rotatably mounted on the side of the cantilever, and a working rod is raised and lowered at the end of the first extension arm. The first extension arm is used to drive the working rod to work in the clearance space.
[0007] Furthermore, the cantilever is suspended on the upper side of the workbench and has an extension arm extending from one end, with the first extension arm rotatably mounted on the side of the extension arm.
[0008] Furthermore, a second extension arm is connected between the extension arm and the first extension arm, with one end of the second extension arm rotatingly engaged with the extension arm and the other end rotatingly engaged with the first extension arm.
[0009] Furthermore, the distance from the axis of the rotatable connection between the first and second extension arms to the axis of the working rod is the same as the distance from the axis of the rotatable connection between the second and extension arms to the axis of the rotatable connection between the second and first extension arms.
[0010] Furthermore, the cantilever includes a support section and a cantilever section, the support section being connected to the workbench surface, and the cantilever section being suspended above the workbench surface.
[0011] Furthermore, a connecting section is provided between the supporting section and the cantilever section, and the connecting section is inclined toward the cantilever section.
[0012] Furthermore, a lifting rod is rotatably provided at the first extension arm, and the end of the working rod away from the worktable is connected to the positioning plate. The lifting rod passes through the positioning plate and is threadedly engaged with the positioning plate, so that the lifting rod controls the lifting and lowering of the working rod.
[0013] Furthermore, a drive wheel and a driven wheel are rotatably provided at the first extension arm. The drive wheel and the driven wheel are connected by a synchronous belt. The driven wheel is sleeved on the outer periphery of the working rod, and a guide groove is provided on the side of the working rod along the axial direction. A guide block is provided on the inner ring of the driven wheel that is in movable cooperation with the guide groove, so that when the driven wheel rotates, it drives the working rod to rotate relative to the first extension arm.
[0014] Furthermore, the upper surface of the second extension arm is flush with or lower than the lower surface of the cantilever section.
[0015] Furthermore, a control system is provided on the side of the worktable to control the working position of the working rod.
[0016] The beneficial effects of this utility model are as follows: the first extension arm and the working rod are suspended by a fixed cantilever, and a clearance space is formed between the cantilever and the worktable to facilitate the movement of the working rod. Then, the rotation of the first extension arm drives the rotation of the working rod, allowing the working rod to enter the clearance space under the cantilever without being interfered with by the cantilever. This eliminates the dead zone between the working rod and the cantilever. Due to the fixed setting of the cantilever and the rotation setting of the first extension arm relative to the cantilever, the first extension arm can not only enter the lower side of the cantilever, but also drive the working rod to a position away from the cantilever for processing. This greatly increases the processing range of the working rod without changing the size of the cantilever, and does not occupy more floor space. Attached Figure Description

[0023] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.
[0024] like Figures 1-3 The present invention provides a cantilever fast hand, including a worktable 1 and a cantilever 2 disposed on the worktable 1. One end of the cantilever 2 is connected to the worktable 1, and the other end is suspended above the worktable 1 so that there is a clearance space between the end of the cantilever 2 and the worktable 1. A first extension arm 3 is rotatably disposed on the side of the cantilever 2, and a working rod 4 is raised and lowered at the end of the first extension arm 3. The first extension arm 3 is used to drive the working rod 4 to work in the clearance space.
[0025] The first extension arm and the working rod are suspended by a fixed cantilever, creating a clearance space between the cantilever and the worktable to facilitate the movement of the working rod. The rotation of the first extension arm drives the rotation of the working rod, allowing it to enter the clearance space under the cantilever without interference from the cantilever. This eliminates dead zones between the working rod and the cantilever. Due to the fixed cantilever and the rotational arrangement of the first extension arm relative to the cantilever, the first extension arm can not only enter the space under the cantilever but also move the working rod to a position away from the cantilever for processing. This greatly increases the processing range of the working rod without changing the cantilever size and without occupying more floor space.
[0026] The end of the working rod facing the worktable can be equipped with clamps, sewing machine heads, and other equipment to assist in sewing and other processing steps.
[0027] Preferably, the cantilever 2 is suspended on the upper side of the workbench and has an extension arm 5 extending from one end, and the first extension arm 3 is rotatably disposed on the side of the extension arm 5.
[0028] Specifically, by extending the arm, the rotation range of the first extension arm can be moved away from the cantilever position, thereby further avoiding possible interference between the cantilever and the working rod, and preventing interference between the connecting line at the first extension arm and the working rod and the cantilever. After the extension arm extends the working range of the working rod, the working range can be extended to one side of the worktable, so that the working position is closer to the side that is easy for the operator to observe, thereby improving the processing effect.
[0029] Preferably, a second extension arm 6 is connected between the extension arm 5 and the first extension arm 3, with one end of the second extension arm 6 rotatingly engaged with the extension arm 5 and the other end rotatingly engaged with the first extension arm 3.
[0030] Specifically, by rotating the first and second extension arms, the working rod can be controlled to perform processing over a wider range and move more flexibly within the existing working range, ensuring that the working rod can quickly move to any position within the working range.
[0031] In one embodiment of this solution, the rotational connection between the extension arm and the second extension arm is controlled by a servo motor, and the rotational connection between the second extension arm and the first extension arm is also controlled by a servo motor to improve the rotational accuracy of both.
[0032] Preferably, the distance from the axis of the rotatable connection between the first extension arm 3 and the second extension arm 6 to the axis of the working rod 4 is the same as the distance from the axis of the rotatable connection between the second extension arm 6 and the extension arm 5 to the axis of the rotatable connection between the second extension arm 6 and the first extension arm 3.
[0033] Specifically, the advantages of the above configuration are as follows: after the first extension arm drives the working rod to rotate, the working rod can move to the rotational connection between the first extension arm and the second extension arm, and the axes of the two coincide. This ensures that there is no dead zone problem when the working rod is used in conjunction with the first extension arm and the second extension arm, thereby ensuring that the working rod can be processed at any position within the existing working range.
[0034] Preferably, the cantilever 2 includes a support section 21 and a cantilever section 22. The support section 21 is connected to the workbench 1, and the cantilever section 22 is suspended above the workbench 1.
[0035] Specifically, the support section supports the cantilever and its components, while the cantilever section suspends the first extension arm, the second extension arm, and the working rod, which effectively ensures the stability of the working rod position and increases its machinability.
[0036] In one embodiment of this solution, the support section is vertically arranged on the upper side of the workbench, the cantilever section is horizontally arranged on the upper side of the workbench, and the cantilever section and the support section are arranged perpendicularly to each other.
[0037] Preferably, a connecting section 23 is provided between the supporting section 21 and the cantilever section 22, and the connecting section 23 is inclined toward the cantilever section 22.
[0038] Specifically, by setting the connecting section at an angle toward the cantilever section, the length of the cantilever section can be effectively increased, the clearance space under the cantilever can be effectively increased, thereby improving the working range of the working rod and ensuring the stability of the connection between the cantilever section and the support section.
[0039] Preferably, a lifting rod 7 is rotatably provided at the first extension arm 3, and the end of the working rod 4 away from the worktable surface 1 is connected to the positioning plate 8, and the lifting rod 7 passes through the positioning plate 8 and is threadedly engaged with the positioning plate 8, so that the lifting rod 7 controls the lifting of the working rod 4.
[0040] Specifically, when controlling the lifting and lowering operation of the working rod, the lifting rod rotates relative to the first extension arm, and then drives the positioning plate to rise and fall through the threaded engagement. This allows the working rod to rise and fall with the positioning plate. During this process, the rotation stroke of the lifting rod is the lifting stroke of the working rod. Thus, by accurately controlling the lifting and lowering of the lifting rod without directly contacting the working rod, the stability and accuracy of the working rod's operation can be ensured.
[0041] In one embodiment of this solution, the lifting rod can be a lead screw structure, and the lead screw can be rotated by a servo motor.
[0042] Preferably, a drive wheel 9 and a driven wheel 10 are rotatably provided at the first extension arm 3. The drive wheel 9 and the driven wheel 10 are connected by a synchronous belt 11. The driven wheel 10 is sleeved on the outer periphery of the working rod 4, and a guide groove 12 is provided on the side of the working rod 4 along the axial direction. A guide block is provided on the inner ring of the driven wheel 10, which is in movable cooperation with the guide groove 12, so that when the driven wheel 10 rotates, it drives the working rod 4 to rotate relative to the first extension arm 3.
[0043] Specifically, the rotation of the drive wheel causes the synchronous belt to drive the driven wheel to rotate. Then, through the connection between the guide block and the guide groove, the driven wheel can drive the working rod to rotate, thereby controlling the rotation of the device connected to the end of the working rod. Furthermore, due to the movable cooperation between the guide block and the guide groove, the guide block and the guide groove can still maintain the connection when the lifting rod controls the lifting of the working rod, so as to ensure that the working rod can rotate and lift at the same time.
[0044] It is worth mentioning that, since the drive wheel and driven wheel adopt a synchronous belt drive, the drive wheel and driven wheel can bypass the lifting rod structure, which makes the structural arrangement of the drive wheel and lifting rod more compact, so as to further reduce the possibility of interference between the components.
[0045] In one embodiment of this solution, a rotating bearing is provided at the connection between the working rod and the positioning plate, so that the working rod can rotate relative to the positioning plate.
[0046] In one embodiment of this solution, the rotation of the drive wheel is controlled by a servo motor.
[0047] Preferably, the upper surface of the second extension arm 6 is flush with or lower than the lower surface of the cantilever section 22.
[0048] Specifically, through the above-mentioned settings, when the second extension arm drives the first extension arm and the working rod to rotate, the working rod can be moved to the lower side of the cantilever section without interference, thereby further improving the working stability of the working rod within the existing working range.
[0049] Preferably, a control system 13 is provided on the side of the worktable 1 to control the working position of the working rod 4.
[0050] Specifically, the control system accurately controls the coordinated use of the first extension arm, the second extension arm, and the working rod to ensure that the working rod moves accurately to any position within the working range.
[0051] In one embodiment of this solution, the control system can be an electronic pattern machine control system to control the movement of the scara robotic arm, and AI can be introduced to complete the relevant sewing work.
[0052] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
