Abstract
Description
Technical Field
[0001] This utility model belongs to the field of carbon fiber badminton racket manufacturing, and more specifically, it relates to a badminton racket blanking unit and a badminton racket grinding device. Background Technology
[0002] After badminton rackets are manufactured, the collection of finished rackets is crucial for ensuring product quality, proper storage, and seamless distribution. This collection process affects both production speed and product quality. Traditionally, badminton rackets are collected manually, which is labor-intensive and inefficient. Current technology has achieved automated collection of badminton rackets through improvements to the device.
[0003] For example, patent application CN112693054A discloses a badminton racket forming production line. The collection of badminton shuttlecocks in this production line is achieved through a collection rack with several layers. The badminton racket is pushed onto the mobile phone holder by a push-out component. The push-out component includes a push-out side plate and several push-out rods. The push-out side plate is disposed on the side of the collection rack and is slidably connected to the collection rack. One end of each push-out rod is connected to the push-out side plate, and each push-out rod is located above each layer of the collection rack.
[0004] Patent application CN118578711A discloses a rapid badminton racket frame forming machine. The device uses a servo motor to drive a magnetic suction plate connected to a support shaft to rotate downwards. At the same time, the magnetic suction plate drives the raw material fitted on the outside of the mold part to rotate downwards. During the rotation, the magnetic suction plate can push the raw material into the storage box for collection by means of the cooperation of the piercing column and the perforation.
[0005] In the above-mentioned badminton racket collection devices, the rackets are stacked in the device. However, badminton rackets, especially carbon fiber rackets, have weak scratch resistance. When multiple rackets are stacked in the box, they are in close contact with each other, and the edges of the racket frames and the surface of the racket shafts are easily scratched due to mutual friction, which affects the quality of the badminton rackets.

[0041] The following detailed description and exemplary embodiments of the present invention can be better understood in conjunction with the accompanying drawings, wherein the elements and features of the present invention are identified by reference numerals.
[0042] Example 1
[0043] Existing badminton rackets include a handle b and a head a located on the handle b, wherein the head a is composed of a frame to form a nestable structure. This application designs a badminton racket cutting unit for badminton rackets that include a handle b and a head a structure.
[0044] In this embodiment, a badminton racket cutting unit is located on the support 10 of the badminton racket polishing device. The cutting unit is as follows: Figure 1-2 As shown, it includes:
[0045] Feeding rod 100, the hammer head a is sleeved on the feeding rod 100, so that the hammer head a slides down on the feeding rod 100 based on gravity;
[0046] And the blocking and buffering component 200: contacts the handle b when it falls.
[0047] The feeding rod 100 is inclined at a certain angle to the horizontal, specifically, as shown in... Figure 3 As shown, the feeding rod 100 includes a fixed end 110 and a free end 120. The fixed end 110 is fixedly connected to the bracket 10 of the badminton racket grinding device. The height of the free end 120 of the feeding rod is higher than the height of the fixed end 110 of the feeding rod, so that the racket head a slides down the feeding rod 100 based on gravity.
[0048] The “feed rod fixing end 110” mentioned here is the end point along the falling direction of the badminton racket;
[0049] The “free end 120 of the feed rod” mentioned here refers to the other end of the feed rod 100, which is close to the initial downward sliding point of the badminton racket.
[0050] By suspending the racket head a on the unloading rod 100, only the edge of the racket head a makes slight contact with the shaft during the downward movement. The contact area is small and the pressure is low. There is no mutual squeezing or friction between the core areas such as the racket face and the shaft, so there is almost no risk of scratches or deformation. After sliding down, the rackets fall naturally or are arranged in an orderly manner with a uniform posture, avoiding collision damage from disorderly stacking. Moreover, the highly uniform posture ensures that the badminton rackets do not obstruct each other, which is beneficial for subsequent quality inspection or handling of the badminton rackets. For example, the racket handle b can be directly positioned without adjusting the complex posture, improving the automation efficiency of packaging and sorting.
[0051] After the pallet head a is suspended from the end of the feeding rod 100, it slides down the rod automatically by gravity, achieving continuous conveying without additional power. Compared with methods such as collection boxes, there is no waiting time for stopping to change boxes, which helps to improve conveying efficiency and adapt to the needs of high-speed production lines.
[0052] Furthermore, since badminton rackets vary in length, grip size, or frame shape, adjusting these parameters each time would be a waste of time. This application addresses this by directly attaching the handle b to the feed bar 100, making it universally applicable for collecting different badminton rackets.
[0053] The feeding rod 100 and the blocking and buffering assembly 200 are both located on the side of the support 10. Specifically, the fixed end 110 of the feeding rod 100 is connected to the side wall of the support 10. The feeding rod 100 is parallel to the side wall of the support 10 and forms a certain space, allowing the badminton racket to slide down from the feeding rod 100. Preferably, the width of the parallel space between the feeding rod 100 and the side wall of the support 10 is not less than the width of the racket head a. This ensures that the racket head a does not interfere with the support 10, thus preventing wear on the racket head a. On the other hand, it forms a guide groove, making it less likely for the badminton racket to shake violently when it falls.
[0054] In one possible implementation, when the badminton racket is transferred from the previous station to the unloading unit, the racket head a is positioned higher than the free end 120 of the unloading rod, allowing the racket head a to be hung on the unloading rod 100. The height of the free end 120 of the unloading rod is higher than the height of the fixed end 110 of the unloading rod, causing the racket head a to slide down the unloading rod 100 under the action of gravity until it stops at the fixed end 110 of the unloading rod and is blocked by the bracket 10, thus realizing the collection of the badminton racket.
[0055] Preferably, the free end 120 of the feed rod 100 is provided with an end cap 130, such as... Figure 5 As shown, the diameter of the end cap 130 is larger than the diameter of the feed rod 100, so that the badminton racket near the free end 120 is intercepted by the end cap 130, thus preventing the badminton rackets from piling up on the feed rod 100 and falling off.
[0056] When the badminton rackets are stationary, they are vertically hung on the feed bar 100. When the first racket slides down the feed bar 100, it is stopped by the bracket 10 at the fixed end 110. When the Nth (N≥2) racket slides down the feed bar 100, two or more rackets are vertically hung on the feed bar 100, arranged parallel to each other. This device is simple and convenient, allowing for rapid collection of badminton rackets. Furthermore, the parallel and closely spaced arrangement of the rackets maximizes space utilization, enabling the collection of more rackets at once.
[0057] The feeding rod 100 of the device is an inclined three-dimensional structure that can be set up along the side of the device, making use of vertical space and saving layout space; the racket after sliding down forms a hanging form, which makes better use of space and is especially suitable for compact assembly line scenarios.
[0058] However, it should be noted that when the badminton racket slides down, the handle b part is prone to wobbling. The greater the falling height, the greater the wobbling amplitude of the badminton racket. In particular, when the badminton racket of this application is transferred from the previous station to the unloading unit, it is in a horizontal state. Due to its own gravity, the handle b will wobble violently when it falls. As a result, when the first badminton racket slides down from the unloading bar 100, it will collide with the bracket 10. When the Nth (N≥2) badminton racket slides down from the unloading bar 100, the latter will collide with the former, which can easily lead to wear on the handle b part. Therefore, this utility model further provides a blocking and buffering component 200 at the position of the handle b to buffer the badminton racket when it falls.
[0059] Specifically, such as Figure 4-6 As shown, the blocking and buffering assembly 200 includes a baffle 210, which is located below the feed rod 100 and contacts the handle b.
[0060] The baffle 210 is driven by a rotary cylinder 220 and can be flipped. Specifically, the rotary cylinder 220 is located on a buffer base 230, which is located on a bracket 10. The rotation of the baffle 210 at the handle b position is achieved by the rotary cylinder 220.
[0061] When in the working position, the baffle 210 flips up to contact the racket handle b, thus cushioning the racket handle b. When the badminton racket falls, the racket handle b first contacts the baffle 210 to stabilize the racket handle b and reduce the shaking of the racket handle b. Then it flips up to separate from the racket handle b, allowing the racket handle b to pass through.
[0062] When the badminton racket passes through the baffle 210, the racket is in a vertical position on the feed bar 100. The contact point between the racket head a and the feed bar 100 is on the same vertical line as the contact point between the racket handle b and the baffle 210. Figure 5As shown, this design ensures that the badminton rackets slide down in a vertical position, and that the rackets are arranged parallel to each other, reducing the risk of wear and scratches caused by collisions between rackets during the slide.
[0063] One way to achieve the "separation from handle b" described herein is to flip the baffle 210 inwards to be parallel to the handle b, so that it does not interfere with the continued downward movement of the handle b. Alternatively, the baffle 210 can be flipped inwards to form a certain angle with the vertical line, as long as it does not interfere with the path of the handle b's continued downward movement. That is, when in the non-working position, the baffle 210 flips to separate from the handle b, allowing the handle b to pass through.
[0064] Preferably, the horizontal distance L1 between the feed rod 100 and the bracket 10 is greater than the horizontal distance L2 between the baffle 210 and the bracket 10. For example... Figure 4 and Figure 5 As shown, when the badminton racket falls horizontally from the free end 120 of the feed bar, the length of the racket head a needs to be considered when it contacts the feed bar 100. Therefore, the feed bar 100 needs to leave a certain distance so that when the racket head a flips to a vertical position, there is a certain amount of space for it to flip.

[0075] The blocking and buffer assembly 200 includes a flip-up baffle 210 located below the feed bar 100, which contacts the handle b when it falls.
