Description

Technical Field

[0001] This utility model belongs to the field of mechanical device technology, and relates to chainsaw devices, and in particular to a circular blade feeding mechanism for a chainsaw guide wheel installation machine. Background Technology

[0002] The circular blade feeding mechanism of the chainsaw guide wheel installation machine is used to produce chainsaw guide wheels. The chainsaw guide wheel is a component of the chainsaw, and the circular blade is a component of the chainsaw guide wheel. The chainsaw guide wheel is typically located at the outer end of the chainsaw guide plate, is mostly circular, and has grooves on its outer side to fit the chain links. It supports and guides the chain to operate smoothly, ensuring cutting efficiency and safety.

[0003] In existing technologies, the feeding of wafers and pre-positioning before assembly are typically done manually. This results in low overall production efficiency and a high risk of malfunctions, leading to a low yield rate. Furthermore, the reliance on manual labor for multiple processes during production increases production costs and increases the risk of accidents. Summary of the Invention

[0004] The purpose of this utility model is to address the above-mentioned problems by providing a circular feeding mechanism for an automatic feeding chainsaw guide wheel installation machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A circular disc feeding mechanism for a chainsaw guide wheel installation machine includes a circular disc support plate, a circular disc dropping hole is provided on the circular disc support plate, a feeding cylinder is provided on one side of the dropping hole, a radial feeding groove is provided between the circular disc feeding cylinder and the circular disc support plate, a circular disc push plate is provided in the radial feeding groove, and the circular disc push plate is connected to a circular disc push plate driving assembly.

[0006] The feed cylinder design with openings at both ends enables continuous stacking feeding, reducing downtime and refueling time. Furthermore, the sheet-like radial feed grooves ensure that the discs do not shift axially during feeding, improving feeding accuracy. A disc pusher plate drive assembly controls the disc pusher plate to continuously push out the discs, achieving automatic feeding.

[0007] In the circular feeding mechanism of the chainsaw guide wheel installation machine described above, the circular push plate is provided with a circular limiting half hole at one end of the circular dropping hole.

[0008] The upper end of the disc feeding hole is provided with an arc-shaped retaining ring on the side away from the disc limiting half-hole. The design of the disc limiting half-hole and the arc-shaped retaining ring can ensure that the disc enters the disc feeding hole accurately and avoid malfunctions.

[0009] In the circular disc feeding mechanism of the aforementioned chainsaw guide wheel installation machine, the circular disc pusher plate drive assembly includes a linear driver mounted on the end of the circular disc pusher plate away from the circular disc discharge hole. The linear driver is connected to the circular disc support plate via a slider rail structure. This direct-drive mode, combining linear drive with a slider rail structure, results in higher feeding efficiency.

[0010] In the circular disc feeding mechanism of the aforementioned chainsaw guide wheel installation machine, the slider rail structure and linear actuator are located at the bottom of the circular disc discharge hole. The circular disc support plate has two strip-shaped grooves located on both sides of the slider rail structure. Connecting rods are installed within these grooves; the upper end of each connecting rod is connected to the circular disc push plate, and the lower end is connected to the slider of the slider rail structure. The arrangement of two strip-shaped grooves eliminates lateral sway, thereby preventing parts from jamming or shifting position, ensuring both output quality and efficiency.

[0011] In the circular disc feeding mechanism of the aforementioned chainsaw guide wheel installation machine, the circular disc discharge hole is equipped with an elastic limiting structure that restricts the circular disc from falling while allowing it to fall when subjected to axial force. A circular disc accommodating gap is left between the elastic limiting structure and the upper end of the circular disc discharge hole. Through the setting of the elastic limiting structure, the circular disc is stably restrained within the discharge hole when no external force is applied, preventing accidental detachment due to vibration or gravity.

[0012] In the circular disc feeding mechanism of the aforementioned chainsaw guide wheel installation machine, the elastic limiting structure includes at least three radially elastic units distributed along the circumferential direction and capable of radial expansion and contraction, located within the circular disc drop hole and near its upper end. The radially expandable and contractive radially elastic units ensure that the circular disc falls precisely only under controlled conditions, further improving the overall feeding accuracy.

[0013] In the circular disc feeding mechanism of the aforementioned chainsaw guide wheel installation machine, the radial elastic unit includes a radial top body, which is disposed within a radial hole in the inner wall of the circular disc dropping hole. A spring is provided between the radial top body and the radial hole. When the circular disc needs to be released during the assembly process, such as when the pressure rod applies axial force, the radial top body with the internal spring can quickly release the constraint of the circular disc, thereby ensuring feeding efficiency.

[0014] In the circular disc feeding mechanism of the aforementioned chainsaw guide wheel installation machine, a circular disc pressure rod is also provided at the upper end of the circular disc dropping hole. The circular disc pressure rod is connected to the circular disc pressure rod drive assembly. The pressure rod and the elastic limiting structure form a collaborative working mechanism: when the radial top body of the elastic limiting structure is clamped by spring pressure, the pressure rod can apply a controllable axial force to break through the critical pressure value, realizing pressure-triggered dropping and collaboratively controlling precise feeding.

[0015] In the circular disc feeding mechanism of the aforementioned chainsaw guide wheel installation machine, the circular disc pressure rod drive assembly includes a lifting slider rail fixed to one side of the upper end of the circular disc discharge hole. The slider of the lifting slider rail is connected to an L-shaped circular disc pressure rod fixing plate at the upper end of the circular disc pressure rod. The circular disc pressure rod fixing plate is connected to a pressure rod linear actuator. The lifting slider rail is fixed to the side frame of the machine frame. The circular disc support plate is detachably fixed to the machine frame by several support columns. The buffer impact body on the side wall of the circular disc pressure rod fixing plate is provided with buffers at both the upper and lower ends. The buffer impact body, in conjunction with the buffers at both ends, absorbs the impact force at the pressure rod stroke limit position, preventing mechanical impact from damaging the rail.

[0016] In the circular disc feeding mechanism of the aforementioned chainsaw guide wheel installation machine, the bottom of the circular disc feeding cylinder is provided with an annular circular disc feeding cylinder base. The bottom of the circular disc feeding cylinder and the circular disc feeding cylinder base are integrated, and the circular disc feeding cylinder base is detachably connected to the circular disc support plate. This detachable fixing structure allows the integrated feeding cylinder and base to form a continuous force-bearing structure with the circular disc support plate, effectively reducing vibration and thus improving feeding accuracy.

[0017] Compared with existing technologies, the circular disc feeding mechanism of this chainsaw guide wheel installation machine has the following advantages: 1. Automatic control of the drive structure enables automatic feeding of circular discs. 2. The stacking design of the feeding cylinder supports batch pre-loading, eliminating the need for frequent refills and allowing for longer continuous production time. 3. Low requirement for manual operation, reducing the risk of human contact and lowering the probability of accidents. Attached Figure Description

Detailed Implementation

[0023] like Figures 1 to 4 As shown, a circular disc feeding mechanism for a chainsaw guide wheel installation machine includes a circular disc support plate 1, a circular disc dropping hole 11 on the circular disc support plate 1, a circular disc feeding cylinder 2 on one side of the circular disc dropping hole 11, a radial feeding groove 3 between the circular disc feeding cylinder 2 and the circular disc support plate 1, a circular disc push plate 31 in the radial feeding groove 3, and a circular disc push plate 31 connected to a circular disc push plate driving assembly 4.

[0024] In this embodiment, the circular disc feeding mechanism of the chainsaw guide wheel installation machine is located at one end of the chainsaw guide wheel installation machine, and a toothed disc feeding mechanism is provided at the other end, with a ball bearing mounting assembly located in the middle. The circular discs are placed in the circular disc feeding cylinder 2, and the circular discs are pushed out sequentially by the circular disc pusher plate 31 located at the bottom of the circular disc feeding cylinder 2, thereby achieving the automatic feeding effect of the circular discs.

[0025] More specifically, the disc pusher plate 31 is provided with a disc limiting half hole 311 at one end of the disc feeding hole 11;

[0026] The upper end of the disc feeding hole 11 is provided with an arc-shaped retaining ring 111 on the side away from the disc limiting half hole 311.

[0027] like Figure 3 As shown, the disc pusher plate drive assembly 4 includes a linear driver 41 disposed on one end of the disc pusher plate 31 away from the disc dropping hole 11. The linear driver 41 is connected to the disc support plate 1 through a slider rail structure 42.

[0028] More specifically, the slider rail structure 42 and the linear actuator 41 are located at the bottom of the disc dropping hole 11. The disc support plate 1 has two strip grooves 12 located on both sides of the slider rail structure 42. The strip grooves 12 are equipped with connecting rods 43. The upper end of the connecting rods 43 is connected to the disc push plate, and the lower end is connected to the slider of the slider rail structure 42.

[0029] More specifically, the disc feeding hole 11 is provided with an elastic limiting structure 13 that can restrict the disc from falling and allow the disc to fall when it is subjected to axial force. A disc receiving gap 131 is left between the elastic limiting structure 13 and the upper end of the disc feeding hole 11.

[0030] More specifically, the elastic limiting structure 13 includes four radially elastic units 132 disposed in the disc feeding hole 11 and near the upper end, distributed along the circumferential direction and capable of radial expansion and contraction.

[0031] More specifically, the radial elastic unit 132 includes a radial top body 133, which is disposed in a radial hole 112 on the inner wall of the disc feeding hole 11, and a spring is provided between the radial top body 133 and the radial hole 112.

[0032] In this embodiment, one end of the spring is fixed to the radial top body 133, and the other end is fixed to the radial hole 112. The diameter of the radial hole 112 is slightly smaller than that of the radial top body 133. The radial top body 133 abuts against the inner side of the radial hole 112 and partially extends into the disc feeding hole 11.

[0033] More specifically, a disc pressing rod 51 is also provided at the upper end of the disc feeding hole 11, and the disc pressing rod 51 is connected to the disc pressing rod driving assembly 5.

[0034] More specifically, the disc pressure bar drive assembly 5 includes a lifting slider rail 52 fixed on one side of the upper end of the disc dropping hole 11. The slider of the lifting slider rail 52 is connected to the L-shaped disc pressure bar fixing plate 53 at the upper end of the disc pressure bar 51. The disc pressure bar fixing plate 53 is connected to the pressure bar linear driver 54. The slider rail 52 is fixed on the side frame 61 of the frame 6. The disc support plate 1 is detachably fixed on the frame 6 by several support columns 62. The buffer impact body 55 on the side wall of the disc pressure bar fixing plate 53 is provided with buffers 56 at both the upper and lower ends.

[0035] More specifically, the bottom of the circular feeding cylinder 2 is provided with a ring-shaped circular feeding cylinder base 21, the bottom of the circular feeding cylinder 2 and the circular feeding cylinder base 21 are integrated, and the circular feeding cylinder base 21 and the circular support plate 1 are detachably connected.

[0036] The working principle of this embodiment is that several discs are arranged in the disc feeding cylinder 2. When the linear driver 41 pulls the disc pusher 31 backward through the slider rail structure 42, the disc at the bottom falls into the radial feeding groove 3. Then the disc pusher 31 extends forward, and the disc limiting half hole 311 at the front end pushes the disc into the disc dropping hole 11.

[0037] The disc is pushed into the disc receiving gap 131 in the disc dropping hole 11. At this time, under the pressure of the disc pressing rod 51, the radial top body 133 retracts into the radial hole 112, and the disc falls to complete the feeding. Then, the linear driver 41 pulls the disc push plate 31 backward through the slider slide rail structure 42, and the pressing rod linear driver 54 drives the disc pressing rod 51 to lift through the lifting slider slide rail 52 to continue the next feeding cycle.
