DETAILED DESCRIPTION

[0023] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] refer to Figure 1-6 The needle row rubber core automatic feeder comprises a base 1 and a support base 10. The base 1 is arranged on the top of the support base 10. A shock-absorbing groove 101 for placing a vibration disk 5 is provided on the base 1. A plurality of first elastic members 102 are provided at the bottom of the shock-absorbing groove 101. A shock-absorbing plate 103 is connected to the side of each first elastic member 102 away from the shock-absorbing groove 101. A plurality of elastic fixing mechanisms for fixing the vibration disk 5 are provided on the inner wall of the shock-absorbing groove 101. The elastic fixing mechanisms are circumferentially arranged with the shock-absorbing groove 101 as the center. The circumferential arrangement of the elastic fixing mechanisms can ensure that the force on the vibration disk 5 is uniform and improve the clamping effect.

[0025] By means of the first elastic member 102, the shock absorbing plate 103 and the elastic fixing mechanism, the vibration disk 5 is placed in the shock absorbing groove 101 and the vibration disk 5 is fixed by the elastic fixing mechanism. When the vibration disk 5 is working, the first elastic member 102 can absorb the vibration generated by the vibration disk 5 when it is working, thereby reducing the vibration transmission, thereby reducing the dynamic load borne by the bolt, thereby reducing the possibility of the bolt loosening, and at the same time, preventing the support seat 10 from being offset due to vibration, thereby improving the stability of the vibration disk 5 when it is working.

[0026] The damping plate 103 can increase the contact area between the bottom of the vibration plate 5 and the first elastic member 102, which means that the vibration plate 5 is supported by more and more uniform support points during operation, thereby preventing the vibration plate 5 from shaking during operation.

[0027] In order to prevent the first elastic member 102 from shifting after long-term use, a plurality of installation grooves 104 are provided at the bottom of the shock-absorbing groove 101, and an anti-deflection column 105 is fixedly connected to each installation groove 104, and each first elastic member 102 is respectively mounted on the anti-deflection column 105. The anti-deflection column 105 can prevent the first elastic member 102 from shifting or being misaligned after long-term use. The anti-deflection column 105 is retractable to improve the service life of the first elastic member 102, and the installation groove 104 provides an installation position for the first elastic member 102, which is convenient for the staff to quickly install the first elastic member 102.

[0028] Specifically, four elastic fixing mechanisms can be provided, and the four elastic fixing mechanisms can provide a stable fixing effect. The elastic fixing mechanism includes a clamping plate 2, a second elastic member 201, and a sliding rod 202. The first elastic member 102 and the second elastic member 201 are both cylindrical compression springs, because the cylindrical compression spring can be compressed and deformed and convert the energy absorption into elastic potential energy, thereby reducing or alleviating vibration, so the first elastic member 102 and the second elastic member 201 are both cylindrical compression springs;

[0029] One end of the second elastic member 201 abuts against the inner wall of the shock absorbing groove 101, and the other end of the second elastic member 201 abuts against the clamping plate 2. The sliding rod 202 is arranged on the side of the clamping block close to the second elastic member 201, and the side of the sliding rod 202 away from the clamping plate 2 passes through the side wall of the base 1 and extends to the outside of the base 1. The second elastic member 201 is sleeved on the sliding rod 202, which can prevent the second elastic member 201 from being offset or misaligned under long-term use, thereby improving the service life of the second elastic member 201.

[0030] When the vibration disk 5 is placed in the shock absorbing groove 101, a clamping plate 2 of an elastic fixing mechanism can be squeezed on one side of the vibration disk 5 to move the clamping plate 2 in the direction of compressing the first elastic member 102. When one side of the vibration disk 5 is placed on the shock absorbing plate 103, the other sides are similar. In order to improve the fixing effect, the side of the clamping plate 2 away from the second elastic member 201 can be made into an arc-shaped structure. The clamping plate 2 of the arc-shaped mechanism can increase the contact area with the surface of the vibration disk 5, thereby improving the fixing effect. When the vibration disk 5 is started, it will transmit vibration to the clamping plate 2, and the clamping plate 2 will have a shock-absorbing effect through the second elastic member 201, thereby improving the stability of the vibration disk 5 during operation. The elastic fixing mechanism can absorb and alleviate the vibration generated by the vibration disk 5 during operation, and can also provide a stable fixing effect.

[0031] In this embodiment, in order to improve the fixing effect of the elastic fixing mechanism, the base 1 is fixedly connected with the containing boxes 3 on all sides, each containing box 3 is provided with a gear 301, a rack 203 is provided on one side of the sliding rod 202, and the gear 301 is meshed with the rack 203, and the two sides of the containing box 3 are fixedly connected with the supporting blocks 302, the gear 301 is connected with the rotating shaft 303 through a flat key, and the two sides of the rotating shaft 303 pass through the supporting block 302 and are rotatably connected with the inside of the supporting block 302, and a locking component for locking the rotating shaft 303 is provided inside the supporting block 302.

[0032] By meshing the gear 301 with the rack 203 and locking the rotating shaft 303 on the gear 301 through the locking assembly, different types of vibration plates 5 can be fixed, thereby improving the application range of the elastic fixing mechanism.

[0033] Specifically, the locking assembly includes a locking cylinder 4, two locking plates 401, and a locking screw 402. A locking block 11 is provided on the top of the support block 302. A locking groove 403 is provided in the locking block 11, and the locking groove 403 is connected to the inside of the support block 302. The locking cylinder 4 is arranged in the support block 302, and the locking cylinder 4 is sleeved on the outer surface of the rotating shaft 303. An opening is provided on one side of the locking cylinder 4, and the two locking plates 401 are respectively arranged on both sides of the opening of the locking cylinder 4. The locking plates 401 and the locking cylinder 4 are both made of aluminum, which will undergo plastic deformation when subjected to force and can quickly return to their original state. At the same time, the locking cylinder 4 can be integrally formed with the two locking plates 401 to reduce processing costs, and the side surface of one locking plate 401 is fixedly connected to the inner wall of the locking groove 403, the locking screw 402 is threadedly connected to the side surface of the locking block 11, and one end of the locking screw 402 abuts against the other locking plate 401.

[0034] When the staff needs to lock the elastic fixing mechanism, they can rotate the locking screw 402, and the locking screw 402 will squeeze a locking plate 401, thereby driving the locking cylinder 4 to clamp the rotating shaft 303, and use the principle of friction to lock the rotating shaft 303 to prevent the rotating shaft 303 from rotating. Anti-slip textures can be set on the side of the locking cylinder 4 close to the rotating shaft 303. The anti-slip textures can increase the contact area between the locking cylinder 4 and the rotating shaft 303, thereby improving the locking effect. In order to facilitate the rotation of the locking screw 402 during work, a rotating block 404 is provided on one side of the locking screw 402, and the outer surface of the rotating block 404 is provided with anti-slip textures. The rotating block 404 can help the staff obtain greater torque, thereby facilitating the staff to rotate the locking screw 402, and the anti-slip textures can improve the comfort of the staff during operation.

[0035] Working principle:

[0036] When the vibration disk 5 is placed in the shock absorbing groove 101, a clamping plate 2 of an elastic fixing mechanism can be squeezed on one side of the vibration disk 5 to make the clamping plate 2 move in the direction of compressing the first elastic member 102. At this time, the sliding rod 202 will extend. Since a rack 203 is provided on the sliding rod 202, when the rack 203 moves, it will drive the gear 301 arranged in the accommodating box 3 to rotate, and the gear 301 will drive the rotating shaft 303 to rotate through the flat key. When the vibration disk 5 is completely lowered, by rotating the locking screw 402, the locking screw 402 will squeeze a locking plate 401, thereby driving the locking cylinder 4 to clamp the rotating shaft 303, and use the principle of friction to lock the rotating shaft 303 to prevent the rotating shaft 303 from rotating, thereby locking the elastic fixing mechanism to improve the stability of the fixation.
