Description

Technical Field

[0001] This invention relates to the field of metal spring manufacturing technology, and specifically to an integrated molding mechanism for producing millimeter-level springs. Background Technology

[0002] In the spring manufacturing process, due to the varying diameters of the materials to be processed, the equipment structure needs to be adjusted during material transport and straightening to accommodate different specifications of metal wire. To address the issue that traditional double-roller structures cannot adapt to changes in wire diameter and spring radius, patent CN202410766256.7 proposes a spring machine with an adjustable function. By optimizing the material traction mechanism and employing an adjustable mounting frame and tilt angle adjustment components, it achieves the function of adjusting the spring forming radius according to different production requirements. However, in practical applications, especially in the production of millimeter-level springs, this device still faces the following problems:

[0003] Firstly, this device primarily adapts to the production needs of springs with different radii by adjusting the distance between the two rollers. However, since the groove structure on the roller surface is fixed, it cannot automatically adjust with changes in spring radius. For larger diameter springs, due to their larger diameter, the matching precision requirement for the roller grooves is lower, and the fit error is acceptable within a certain range. Therefore, adjusting the roller spacing alone can meet the processing requirements. However, this deficiency is particularly prominent in the production of millimeter-sized springs. At this stage, the spring diameter is extremely small, and the requirement for the fit between the rollers and the material is extremely high. If only the roller spacing is adjusted without simultaneously adjusting the groove size, it is very easy to cause poor fit between the rollers and the outer diameter of the spring, thereby affecting the feeding accuracy and molding stability.

[0004] Secondly, existing dual-roller structures typically use a single-roller drive to feed the material. For larger diameter springs, the metal wire used is thicker and harder, and the feeding process is relatively stable, so this drive method can basically meet the usage requirements. However, due to structural limitations, some slippage error may still occur, affecting the consistency of spring length. In the production of miniature springs, this problem is further amplified. The thin, low-rigidity wire places higher demands on the synchronization and control precision of the feeding system. Single-roller drive is significantly insufficient in terms of torque transmission, synchronization, and response sensitivity, easily causing problems such as material slippage, uneven feeding, or deviation, which in turn affects the quality and dimensional consistency of the spring. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide an integral molding mechanism for the production of millimeter-level springs, so as to solve the problems existing in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution of the present invention is an integrated molding mechanism for millimeter-level spring production, including a feeding component and a molding component. The feeding component includes feeding wheels arranged vertically adjacent to each other. Each feeding wheel includes a male body and a female body, both of which have a taper. The small end face of the male body and the small end face of the female body are arranged adjacent to each other and are slidably connected and interlocked, so that the side of the feeding wheel forms an annular groove. By controlling the degree of connection between the male body and the female body, the depth and width of the groove can be adjusted. The feeding wheel is divided into a first feeding wheel and a second feeding wheel. By controlling the vertical distance between the first feeding wheel and the second feeding wheel, the spacing of the feeding wheels can be adjusted. By adjusting the groove and / or adjusting the spacing of the feeding wheels, the feeding component can meet the feeding requirements for the production of springs of different diameters.

[0007] Preferably, the male body and the female body are coaxially arranged, and both the male body and the female body have tapered structural members arranged in a ring array. There are gaps between adjacent tapered structural members, and the male body or the female body uses the gaps as sliding grooves. The sliding grooves of the male body and the tapered structural members of the female body are adapted to each other, and the tapered structural members of the male body and the sliding grooves of the female body are adapted to each other. The axial end face width of only one tapered structural member on the male body and the female body remains unchanged to ensure that sliding control can be performed between the male body and the female body.

[0008] Furthermore, the male and female bodies each have a sliding rod and a sliding hole, both located on the axis of the male and female bodies; each of the male and female bodies has a mounting plate on its large end face, and the mounting plate is fixedly connected to the tapered structural member; the feeding component is equipped with a fixing plate and a control plate, and the mounting plate is rotatably mounted on the fixing plate and the control plate; by controlling the distance between the fixing plate and the control plate, the sliding adjustment of the male and female bodies can be achieved.

[0009] Preferably, the groove is a V-shaped groove; when the taper ratio of the male body and the female body is both two, the grooves on the first feed wheel and the second feed wheel form a square shape in the feeding direction; by controlling the degree of connection between the male body and the female body, the feeding component can meet the feeding requirements for springs of different diameters.

[0010] Furthermore, the feeding component is equipped with a driving component, which is located on one side of the fixed plate on the feeding component. The driving component includes a first gear and a second gear respectively disposed on the first feeding wheel and the second feeding wheel; the dual-wheel synchronous drive of the feeding component is realized by the transmission of the first gear and the second gear.

[0011] Furthermore, the driving component includes a first connecting rod and a second connecting rod, one end of the first connecting rod and one end of the second connecting rod are rotatably connected to each other, and the other ends of the first connecting rod and the second connecting rod are respectively oscillatingly mounted on the first feed wheel and the second feed wheel; a third gear is provided on the rotatable connection end of the first connecting rod and the second connecting rod, and a fourth gear is provided on the second connecting rod. The third gear meshes with the first gear, the fourth gear meshes with the third gear, and the fourth gear meshes with the first gear; the first gear, the second gear, and the third gear have the same specifications; the transmission of the first gear, the second gear, the third gear, and the fourth gear realizes the synchronous dual-wheel drive of the feeding component; when the distance between the first feed wheel and the second feed wheel is adjusted, the first connecting rod and the second connecting rod drive the third gear and the fourth gear to move, so that the driving component realizes the synchronous dual-wheel drive of the feeding component with different distances.

[0012] Furthermore, the feeding components are a first feeding component and a second feeding component arranged horizontally adjacent to each other. By feeding the first feeding component and the second feeding component synchronously, the straightness of the feeding during the conveying process is ensured, thereby effectively avoiding adverse effects on the subsequent production and molding of springs due to material deviation or deformation. The first feeding component and the second feeding component are both set on the same fixed plate and the same control plate to ensure synchronous control of the first feeding component and the second feeding component.

[0013] Furthermore, a fifth gear and a sixth gear are provided on the fixed plate. The fifth gear and the sixth gear mesh with each other, and the sixth gear meshes with the first gear or the second gear. The fifth gear is connected to the second feeding component. Under the action of the fifth gear and the sixth gear, the driving component synchronously drives the first feeding component and the second feeding component.

[0014] Preferably, the material includes a straightening component, which uses the feed wheel to straighten the material.

[0015] The main technical effects of this invention are reflected in the following aspects:

[0016] This invention, by arranging the first and second feeding components horizontally adjacent to each other and synchronously driving them through a unified control system, ensures that the wire maintains a straight-line motion before entering the forming component. This not only improves the straightness during the feeding process but also reduces the impact of material offset or deformation on subsequent spring forming. Furthermore, the design of the fifth and sixth gears enables mechanical rigidity synchronization between the two feeding components, maintaining a stable transmission relationship even with varying spacing, further enhancing the system's reliability and stability.

[0017] A multi-stage gear transmission system, including a first gear, a second gear, a third gear, and a fourth gear, was introduced to achieve high-precision synchronous rotation of the first and second feed wheels. This system not only ensures synchronous rotation of both wheels but also adapts to different spacing between the first and second feed wheels. Specifically, when the distance between the first and second feed wheels changes (for example, to accommodate the production of springs with different diameters), the first and second connecting rods drive the third and fourth gears to move accordingly. Because the relative positions of these gears are connected through mechanical linkage, even when the spacing changes, the gears maintain good meshing, thus maintaining stable synchronous drive performance. This design greatly increases the flexibility of the equipment, allowing it to easily meet the production needs of springs of various specifications without requiring additional adjustments to the transmission system or replacement of components.

[0018] By dynamically adjusting the groove size by controlling the connection degree between the male and female components, high-precision clamping and stable feeding of wires of different diameters are achieved. Utilizing the groove formed when the male and female components slide relative to each other, the width and depth of the groove can be precisely changed according to actual needs, ensuring optimal clamping force. This not only improves the straightness and stability during the feeding process and avoids wire deviation or slippage caused by unstable clamping, but is also particularly suitable for fine-diameter wires used in the production of millimeter-level springs.

[0026] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, so as to make the technical solution of the present invention easier to understand and master. In the embodiments, it should be understood that the terms "middle," "upper," "lower," "top," "right side," "left end," "above," "back," "center," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. In addition, unless otherwise specified in this specific embodiment, the connection or fixing method between components can be achieved by bolt fixing, pin fixing, or pin connection commonly used in the prior art, etc., and therefore will not be described in detail in this embodiment.

[0027] The integrated molding mechanism for producing millimeter-level springs provided by this invention is mainly used in the integrated molding production of springs, especially the production of millimeter-level springs, but it is not limited thereto and can also be used in other similar or identical production processes.

[0028] Example 1

[0029] See Figure 1 , Figure 2To address the problems of low feeding accuracy and poor forming stability in existing spring production machines, this embodiment discloses an integrated forming mechanism for millimeter-level spring production, suitable for wires with various cross-sectional shapes (such as cylindrical, elliptical, and rectangular). It includes a feeding component 1 and a forming component 2. The feeding component 1 includes vertically adjacent feeding wheels 11, which are divided into a first feeding wheel 13 and a second feeding wheel 14. Each feeding wheel 11 includes a male body 111 and a female body 112, both of which have a taper. The small end face of the male body 111 and the small end face of the female body 112 are arranged adjacent to each other, and the male body 111 and the female body 112 are slidably connected and interlocked, so that the side of the feed roller 11 forms an annular groove 12. By controlling the degree of connection between the male body 111 and the female body 112, the depth and width of the groove 12 can be adjusted. This breaks through the limitations of the traditional fixed groove 12 structure, allowing the feed roller 11 to adaptively match spring wires of different diameters, which is especially suitable for the high-precision feeding requirements of millimeter-level micro springs. For example, when processing fine-diameter wires, by reducing the width of the groove 12 and increasing the depth of the groove 12, the contact area between the roller and the wire can be effectively increased, preventing slippage or offset caused by poor fit. By controlling the vertical distance between the first feed roller 13 and the second feed roller 14, the spacing of the feed roller 11 can be adjusted. By adjusting the groove 12 and / or adjusting the spacing of the feed roller 11, the feeding component 1 can meet the production feeding needs of springs of different diameters. By adjusting the vertical distance between the first feed roller 13 and the second feed roller 14, the forming requirements of springs with different radii can be accommodated. This adjustment function works in conjunction with the groove 12 size adjustment function to achieve comprehensive optimization of the feeding system. For example, when processing springs with larger radii, appropriately widening the spacing between the feed rollers 11 and using a shallower groove 12 can meet the requirements; while when processing miniature helical compression springs, it is necessary to reduce the spacing and precisely adjust the shape of the groove 12 to ensure the continuity and consistency of material feeding.

[0030] Regarding "the small end face of the male body 111 and the small end face of the female body 112", the male body 111 and the female body 112 can be a cone and a frustum, respectively. In this embodiment, a frustum is used. The explanation of the small end face and the subsequent large end face is as follows: a frustum has an arc-shaped conical surface, and the end faces on both sides are the small end face and the large end face, which refer to the area.

[0031] See Figure 3 , Figure 4 , Figure 5The original feeding component 1 has undergone deep structural optimization: the male body 111 and the female body 112 are coaxially arranged, and both the male body 111 and the female body 112 have tapered structural members 113 arranged in a ring array. There are gaps between adjacent tapered structural members 113, and the male body 111 or the female body 112 uses the gaps as grooves 114. The grooves 114 of the male body 111 and the tapered structural members 113 of the female body 112 are adapted to each other, and the tapered structural members 113 of the male body 111 and the grooves 114 of the female body 112 are adapted to each other. For example, when the tapered structural member 113 on the male body 111 is inserted into the groove 114 of the female body 112, the two form a nested structural relationship. This design makes the relative displacement between the male body 111 and the female body 112 directional and stable, avoiding poor contact or jamming caused by misalignment. The axial end face width of the tapered structural member 113 on both the male body 111 and the female body 112 remains constant to ensure sliding control between them. This specific structural member acts as a "reference guide," providing positioning and limiting during sliding to prevent structural instability caused by multi-point synchronization errors, thus ensuring the accuracy of the groove 12 adjustment. By utilizing the tapered structural member 113 between the male body 111 and the female body 112 in conjunction with the sliding groove 114, dynamic adjustment of the groove 12 size is achieved, significantly improving the contact accuracy between the roller and the wire, making it particularly suitable for clamping small-diameter wires.

[0032] See Figure 4 , Figure 5 The male body 111 and the female body 112 each have a sliding rod 115 and a sliding hole 116, both located on the axis of the male body 111 and the female body 112. This not only enhances the coaxiality and rigidity of the connection between the two but also provides physical support and motion guidance for subsequent adjustment actions. This axial sliding fit allows the male body 111 and the female body 112 to achieve precise displacement under the drive of the control system, thereby changing the size of the formed annular groove 12. Both the male body 111 and the female body 112 have mounting plates 117 on their large end faces. The mounting plates 117 and the tapered structural member 113 are fixedly connected. The mounting plates 117 and the tapered structural member 113 are connected in an integrated or fastened manner to ensure the stability and load-bearing capacity of the overall structure.

[0033] See Figure 2The feeding component 1 is equipped with a fixing plate 15 and a control plate 16, and the mounting plates 117 are rotatably mounted on the fixing plate 15 and the control plate 16. By controlling the distance between the fixing plate 15 and the control plate 16, the sliding adjustment of the male body 111 and the female body 112 can be achieved. By applying the displacement of the control plate 16, the embedding depth between the male body 111 and the female body 112 can be precisely controlled, thereby changing the width and depth of the annular groove 12. For example, when processing spring wire, the control system automatically calculates the required groove 12 size and drives the control plate 16 to move via a servo motor, so that the embedding degree between the male body 111 and the female body 112 reaches the optimal matching state, thereby ensuring that the roller and the wire are in close contact and improving the feeding stability.

[0034] See Figure 6 By optimizing the structural design of the drive component 3, not only is the response speed and control accuracy of the feeding system improved, but the problems of slippage error and uneven feeding that are prone to occur in the processing of micro springs using traditional single-wheel drive are also effectively solved. Specifically:

[0035] The feeding component 1 is equipped with a driving component 3, which is located on one side of the fixed plate 15 on the feeding component 1. The driving component 3 includes a first gear 31 and a second gear 32 respectively disposed on the shaft ends of the first feeding wheel 13 and the second feeding wheel 14. The dual-wheel synchronous drive of the feeding component 1 is realized by the transmission of the first gear 31 and the second gear 32.

[0036] The driving component 3 includes a first connecting rod 33 and a second connecting rod 34. One end of the first connecting rod 33 and one end of the second connecting rod 34 are rotatably connected to each other. The other ends of the first connecting rod 33 and the second connecting rod 34 are respectively oscillatingly mounted on the first feed wheel 13 and the second feed wheel 14, forming a dynamically supported connecting rod structure. This allows the connecting rods to adjust their angles when the distance between the feed wheels 11 changes, ensuring the continuity and stability of the transmission path. A third gear 35 is provided on the rotatable connection end of the first connecting rod 33 and the second connecting rod 34, and a fourth gear 36 is provided on the second connecting rod 34. The third gear 35 meshes with the first gear 31, the fourth gear 36 meshes with the third gear 35, and the fourth gear 36 meshes with the first gear 31. The first gear 31, the second gear 32, and the third gear 35 have the same specifications to ensure a consistent transmission ratio, thereby achieving complete synchronous rotation between the first feed wheel 13 and the second feed wheel 14. The feeding component 1 is synchronously driven by two wheels through the transmission of the first gear 31, the second gear 32, the third gear 35 and the fourth gear 36. When the distance between the first feeding wheel 13 and the second feeding wheel 14 is adjusted, the first connecting rod 33 and the second connecting rod 34 drive the third gear 35 and the fourth gear 36 to move, so that the driving component 3 can synchronously drive the feeding component 1 with different distances.

[0037] The linkage system consisting of the first gear 31, the second gear 32, the third gear 35, and the fourth gear 36 enables synchronous driving of the first feed wheel 13 and the second feed wheel 14. Simultaneously, the multi-stage gear meshing design not only improves transmission efficiency but also significantly enhances torque transmission stability, making it particularly suitable for micro-spring processing scenarios requiring high-frequency start-stop or variable-speed operation. When the distance between the first feed wheel 13 and the second feed wheel 14 changes (e.g., adjusted according to the spring radius), the first connecting rod 33 and the second connecting rod 34 will swing and displace with the movement of the feed wheel 11, causing the positions of the third gear 35 and the fourth gear 36 to adjust synchronously. This ensures that the gears maintain good meshing under different spacing conditions, thereby maintaining stable synchronous driving performance.

[0038] See Figure 6 Based on the existing single-stage feeding adjustment and dual-wheel drive, a horizontal dual-stage synchronous feeding structure is further introduced. Specifically, the first feeding component 37 and the second feeding component 38 are arranged horizontally adjacent to each other, and their coordinated operation is achieved through a unified control system. This improves the straightness and stability during wire conveying and effectively avoids spring forming defects caused by material offset or deformation. The specific settings are as follows:

[0039] The feeding components 1 consist of a first feeding component 37 and a second feeding component 38 arranged horizontally adjacent to each other. Synchronous feeding of the first feeding component 37 and the second feeding component 38 ensures the straightness of the feed during the conveying process, effectively preventing adverse effects on subsequent spring production and molding caused by material deviation or deformation. The first feeding component 37 is located near the raw material inlet, responsible for initial traction and coarse adjustment; the second feeding component 38 is located behind it, receiving the wire from the previous section and performing fine adjustment and stable output. The dual-stage structure allows for secondary correction of the metal wire before it enters the molding component 2, ensuring it remains on the ideal trajectory, thereby improving the quality of subsequent spring molding. Both the first feeding component 37 and the second feeding component 38 are mounted on the same fixed plate 15 and control plate 16, ensuring synchronous control of the first feeding component 37 and the second feeding component 38. Each feeding component 1 consists of a pair of adjustable feeding wheels 11 (including male body 111 and female body 112) and is equipped with the aforementioned gear-linkage transmission system for adjusting the roller groove 12 and driving the two wheels synchronously.

[0040] The fixed plate 15 is equipped with a fifth gear 39 and a sixth gear 40. The fifth gear 39 and the sixth gear 40 mesh with each other, and the sixth gear 40 meshes with either the first gear 31 or the second gear 32. The fifth gear 39 is connected to the second feeding component 38. Under the action of the fifth gear 39 and the sixth gear 40, the driving component 3 synchronously drives the first feeding component 37 and the second feeding component 38. The power source that originally only drove a single feeding component 1 is extended to two feeding components 1. Mechanical rigidity synchronization is achieved through gear meshing, ensuring that the two are completely consistent in rotational speed, torque output, and position changes.

[0041] See Figure 1 The system includes a straightening component 4. Straightening is an indispensable step in the spring production process. It is mainly used to eliminate bending and twisting of the wire that may occur during transportation or storage, ensuring that the wire enters the subsequent processing stage in a straight state. The straightening component 4 uses the feed roller 11 to straighten the material. Straightening of the material is achieved mainly by the rotation of the feed roller 11 and the pressure it applies to the wire.

[0042] Example 2

[0043] This embodiment discloses an integrated molding mechanism for producing millimeter-level springs. Based on the aforementioned embodiment, the shape design of the feed wheel 11 and groove 12 is further optimized, and adaptive clamping of spring wires of different diameters is achieved through a specific taper ratio.

[0044] Specifically, the groove 12 is a V-shaped groove, that is, its cross-section is "V" shaped, and its two sides are formed by the conical surfaces of the male body 111 and the female body 112, which are used to clamp the metal wire and provide sufficient friction to achieve stable feeding.

[0045] When the taper ratio of both the male body 111 and the female body 112 is 2 (i.e., the taper angle is 1:2), it means that for every unit length extension, the diameter changes by 0.5 units. The grooves 12 on the first feed roller 13 and the second feed roller 14 form a square shape in the feeding direction. This configuration is suitable for clamping spring wires with standard circular cross-sections, effectively improving clamping stability and reducing the risk of wire rolling deviation. By simply controlling the degree of connection between the male body 111 and the female body 112, the feeding component 1 can meet the feeding requirements for springs of different diameters. That is, the depth of sliding embedding can dynamically adjust the size of the groove 12 to adapt it to spring wires of different diameters.

[0046] For example, when processing wires with a diameter of 0.6mm, the width of the groove 12 is appropriately reduced and the depth of the groove 12 is increased to ensure that the wire is reliably clamped. When changing to 1.2mm wires, the embedding degree is relaxed, and the space of the groove 12 is enlarged to avoid excessive clamping that could flatten the wire or cause excessive driving resistance. Therefore, by simply adjusting the connection degree between the male body 111 and the female body 112, high-precision feeding control of springs with different diameters can be achieved without replacing the roller assembly, significantly improving the equipment's flexible production capacity and ease of operation.

[0047] Example 3

[0048] This embodiment discloses a method for using an integrated molding mechanism for producing millimeter-level springs. The specific method is as follows:

[0049] S1. Preparations:

[0050] 1) Wire selection and loading: Select appropriate metal wire according to the type of spring to be produced (such as diameter, material, etc.); correctly install the selected wire at the inlet of the feeding system to ensure that the wire can smoothly enter the feeding wheel 11.

[0051] 2) Equipment inspection: Check whether all mechanical parts are operating normally, including but not limited to the feed roller 11, straightening component 4, drive system and its connecting parts; confirm that the control system and related software have been started and can receive and process input commands.

[0052] 3) Initial parameter setting: Input various parameters of the target spring into the control system, such as wire diameter, spring outer diameter, number of turns, pitch, etc.; the system automatically calculates and sets the necessary parameters based on these inputs, such as the groove 12 size, feed wheel 11 spacing, and drive torque, etc.

[0053] S2. Feeding and Straightening:

[0054] 1) Groove 12 size adjustment: Based on the diameter of the selected wire, the embedding depth between the male body 111 and the female body 112 is adjusted through the control system, thereby adjusting the width and depth of the V-groove 12 to achieve the best clamping effect.

[0055] 2) Straightening process: Start the straightening component 4 and use the feed rollers 11 to perform preliminary straightening on the material; ensure that the wire remains straight before entering the forming component 2, and reduce quality problems caused by bending. The pressure and spacing of the straightening rollers can be adjusted as needed to accommodate wires of different hardness and diameter.

[0056] S3, Synchronous Drive Control:

[0057] 1) Dual-wheel synchronous drive start: Turn on the drive system to make the first feed wheel 13 and the second feed wheel 14 start to rotate synchronously. Under the action of the fifth gear 39 and the sixth gear 40, the precise synchronization of the two sets of feed wheels 11 is ensured, avoiding possible slippage or deviation during the feeding process.

[0058] S4, Spring Forming:

[0059] 1) Mold adjustment: Based on the preset spring parameters, the angle and stroke of the forming component 2 are automatically changed or adjusted to prepare for the forming of the upcoming wire.

[0060] 2) Continuous forming operation: The wire enters the forming part 2 under the traction of the drive system. After a series of processes such as winding, compression or stretching, it forms a spring of a predetermined shape. The control system is responsible for coordinating the action sequence of each part to ensure seamless connection of each link and improve production efficiency.

[0061] Furthermore, as is common knowledge in this industry, the fixed plate 15 and control plate 16 mentioned above are equipped with linear moving parts for adjusting the distance between them, the drive component 3 is equipped with a drive motor, and the specific structural composition of the molding component 2, as well as the control system in the usage method, are all common knowledge; therefore, their principles and structures will not be elaborated further.

[0062] Of course, the above are just typical examples of the present invention. In addition, the present invention may have many other specific embodiments. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by the present invention.

The driving component includes a first gear and a second gear respectively disposed on the first feeding wheel and the second feeding wheel; the dual-wheel synchronous drive of the feeding component is realized by the transmission of the first gear and the second gear. The driving component includes a first connecting rod and a second connecting rod. One end of the first connecting rod and one end of the second connecting rod are rotatably connected to each other. The other ends of the first connecting rod and the second connecting rod are respectively oscillatingly mounted on the first feed wheel and the second feed wheel. A third gear is provided on the rotatable connection end of the first connecting rod and the second connecting rod, and a fourth gear is provided on the second connecting rod. The third gear meshes with the first gear, the fourth gear meshes with the third gear, and the fourth gear meshes with the first gear. The first gear, the second gear, and the third gear have the same specifications. The transmission of the first gear, the second gear, the third gear, and the fourth gear realizes the synchronous dual-wheel drive of the feeding component. When the distance between the first feed wheel and the second feed wheel is adjusted, the first connecting rod and the second connecting rod drive the third gear and the fourth gear to move, so that the driving component realizes the synchronous dual-wheel drive of the feeding component with different distances.
