[0002] Steel strip refers to a high-precision stamping product of hardware terminals, which is mainly used for the conductive pins of electronic products and is widely used in various connectors.

[0003] The existing steel strip is pulled in production by using two rollers that abut each other. The steel strip is placed between the two rollers. The two rollers rotate, generating friction between the steel strip and the rollers, driving the steel strip forward so that the steel strip can be subsequently stamped.

[0004] However, in the prior art, when the steel strip is pulled, the steel strip may slip due to unstable pulling, and the product may be easily scrapped during subsequent die punching of the steel strip, resulting in losses. Utility Model Content

[0005] Based on the above situation, the main purpose of this utility model is to provide a needle wheel powered pulling machine to solve the problem that the existing technology is prone to slipping of the steel strip due to unstable traction when pulling the steel strip, and the product is easily scrapped during subsequent die punching and cutting of the steel strip, causing losses.

[0006] In order to achieve the above purpose, the technical solution adopted by the present utility model is as follows:

[0007] A pin wheel powered material pulling machine comprises a pin wheel and a lower pressure wheel;

[0008] The pin wheel is located at the lower side of the lower pressure wheel, and the lower pressure wheel can abut against the pin wheel;

[0009] A plurality of needle protrusions are fixed on the circumferential surface of the needle wheel. The plurality of needle protrusions are evenly arranged along the circumferential direction of the needle wheel. The needle protrusions can be placed in the circular holes on the surface of the steel strip.

[0010] Preferably, the machine further comprises a motor, the pin wheel is coaxially arranged with the output shaft of the motor, and the output shaft of the motor is fixedly connected to the pin wheel.

[0013] A connecting arm is provided on the connecting plate, one end of the connecting arm is rotatably connected to the connecting plate, and the lower pressure wheel is rotatably connected to the middle portion of the connecting arm.

[0014] Preferably, the vertical plane where the axis of the lower pressure wheel is located is the first plane, and the vertical plane where the axis of the pin wheel is located is the second plane;

[0015] The first plane and the second plane do not coincide with each other.

[0016] Preferably, a handle is provided at one end of the connecting arm away from the connecting plate, a support rod is fixedly connected to the upper side of the end of the connecting arm away from the connecting plate, and the handle is fixedly connected to the end of the support rod away from the connecting arm.

[0017] The beneficial effect of the present invention is that before the steel strip is pulled, in order to achieve stable pulling, the staff can punch circular holes with equal spacing on the surface of the coiled steel strip.

[0026] The present invention is described below based on embodiments, but the present invention is not limited to these embodiments. In the following detailed description of the present invention, some specific details are described in detail. In order to avoid obscuring the essence of the present invention, well-known methods, processes, procedures, and components are not described in detail.

[0027] Furthermore, persons of ordinary skill in the art will appreciate that the figures provided herein are for illustration purposes only and are not necessarily drawn to scale.

[0028] Unless the context clearly requires otherwise, throughout the specification and claims, the words "include," "comprising," and similar words should be construed in an inclusive sense rather than an exclusive or exhaustive sense; that is, in the sense of "including but not limited to."

[0029] In the description of the present invention, it should be understood that the terms "first," "second," etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance. In addition, in the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0030] Reference Figure 1 The utility model provides a needle wheel power pulling machine, including a motor 1, a needle wheel 2 and a lower pressure wheel 3. The motor 1 is connected to the needle wheel 2 and is used to transmit power to the needle wheel 2 so that the needle wheel 2 rotates. The lower pressure wheel 3 is placed on the upper side of the needle wheel 2 to press against the steel belt 4. The steel belt 4 is placed between the needle wheel 2 and the lower pressure wheel 3. The rotation of the lower pressure wheel 3 can drive the steel belt 4 to move, thereby achieving a traction effect.

[0031] Reference Figure 1-Figure 3 A fixing bracket 11 is fixed to one end of the motor 1, and the lower end of the fixing bracket 11 can be fixed to an external workbench for fixing the material pulling tractor. The pin wheel 2 is coaxially arranged with the output shaft of the motor 1, and the output of the motor 1 is passed through the fixing bracket 11 and fixed to the pin wheel 2. When the motor 1 is working, the rotation of the output shaft of the motor 1 can drive the pin wheel 2 to rotate.

[0032] The lower pressure wheel 3 is rotatably arranged above the motor 1, and the lower side of the lower pressure wheel 3 can abut against the pin wheel 2. The steel belt 4 can pass through the abutment position of the lower pressure wheel 3 and the pin wheel 2, so that the lower pressure wheel 3 and the pin wheel 2 can clamp the steel belt 4. It should be noted that a positioning spring (not shown in the figure) can be provided above the lower pressure wheel 3. The positioning spring can push the lower pressure wheel 3 to move downward. When the steel belt 4 is not installed, the lower pressure wheel 3 directly abuts against the pin wheel 2. When the steel belt 4 is installed, the lower pressure wheel 3 abuts against the steel belt 4.

[0033] As an embodiment, a connecting plate 12 is fixed to the upper side of the motor 1, and a connecting arm 13 is provided on the connecting plate 12. One end of the connecting arm 13 is rotatably connected to the connecting plate 12, and the lower pressure wheel 3 is rotatably connected to the middle part of the connecting wall. One end of the positioning spring can be installed on the connecting arm 13, and the other end is installed on the external fixed structure. By rotating the connecting arm 13 and pressing the positioning spring, the lower pressure wheel 3 can be stably pressed above the steel belt 4. Furthermore, a support rod 131 is fixed to the end of the connecting arm 13 away from the connecting plate 12, and a handle 132 is fixed to the upper end of the support rod 131 for operation.

[0034] A plurality of pin protrusions 21 are fixed to the circumference of the pin wheel 2, evenly spaced along its circumference. These pin protrusions 21 can be positioned within circular holes 41 on the surface of the steel strip 4. The distance between adjacent circular holes 41 on the steel strip 4 is equal to the arc length between adjacent pin protrusions 21. Before the steel strip 4 is pulled, to ensure stable pulling, workers can punch circular holes 41 with equal spacing on the surface of the coiled steel strip 4. During pulling, the pin wheel 2 rotates, and the pin protrusions 21 of the pin wheel 2 are inserted into the circular holes 41. This allows the steel strip 4 to be stably moved for subsequent stamping, ensuring that the steel strip 4 does not slip due to unstable pulling, and thus ensuring the quality of subsequent die punching.

[0035] As an embodiment, an annular groove 31 is formed on the circumference of the lower pressure wheel 3. When the lower pressure wheel 3 is in contact with the needle wheel 2, the pin protrusion 21 can be located in the annular groove 31. By providing the annular groove 31 for accommodating the pin protrusion 21, the inability of the lower pressure wheel 3 and the needle wheel 2 to contact each other due to the pin protrusion 21 can be avoided, so that the surfaces of the lower pressure wheel 3 and the needle wheel 2 can completely contact and hold the steel belt 4, so that the steel belt 4 can be clamped and pulled by the lower pressure wheel 3 and the needle wheel 2 while the pin protrusion 21 is engaged with the circular hole 41.

[0036] As an embodiment, the vertical plane where the axis of the lower pressure wheel 3 is located is the first plane α, and the plane where the axis of the pin wheel 2 is located is the second plane β. The first plane α and the second plane β do not overlap, so that the lower pressure wheel 3 and the pin wheel 2 can be staggered. Figure 4 and Figure 5 If the first plane and the second plane coincide with each other, the steel belt 4 will only have one contact point with the pinwheel 2 at the traction position and before the traction position, and the pulling force on the steel belt 4 will be concentrated at the tangent point, resulting in the steel belt 4 being unstressed and easily damaged. However, with the position setting of the present application, the steel belt 4 can be placed on the pinwheel 2 before the traction position, so that there is a larger contact surface between the steel belt 4 and the pinwheel 2, thereby increasing the pulling force and protecting the product. It should be noted that the traction position is the contact position between the lower pressure wheel 3 and the pinwheel 2.

[0037] The working principle of the present invention is as follows: before the steel strip 4 is pulled, in order to achieve stable pulling, the staff can punch circular holes 41 with equal spacing on the surface of the coiled steel strip 4. During pulling, the pin wheel 2 rotates, and the pin protrusions 21 of the pin wheel 2 are inserted into the circular holes 41, so that the steel strip 4 can be moved stably for subsequent punching, ensuring that the steel strip 4 will not slip due to unstable pulling, and ensuring the quality of subsequent die punching.

[0038] Those skilled in the art will appreciate that, provided there is no conflict, the above preferred solutions can be freely combined and superimposed.

[0039] It should be understood that the above-mentioned embodiments are merely illustrative and non-restrictive. Without departing from the basic principles of the present invention, various obvious or equivalent modifications or substitutions that can be made by those skilled in the art to the above-mentioned details will be included in the scope of the claims of the present invention.
