[0031] In order to more conveniently explain the feeding mechanism provided in the embodiment of the present application, the technical solution of the present application will be explained in detail below as an example rather than a limitation.

[0032] The feeding mechanism provided by the present application is now described in detail with reference to the accompanying drawings.

[0033] Example 1

[0034] See also Figure 1-5 A feeding mechanism includes a synchronous belt and a consumable box 2, wherein the synchronous belt is provided with a claw assembly 1, and the consumable box is provided with a card slot 201.

[0035] like Figure 2 As shown, the claw assembly 1 includes a claw body 101, a baffle 102, and a tongue 103, wherein the claw body 101 is provided with an extension arm 1011, and the extension arm 101 is connected to the baffle 102, specifically, the extension arm 1011 is located at the center position of the baffle 102 in the length direction.

[0036] In order to allow the tongue to have a certain extension and contraction range, the tongue 103 does not directly contact the surface of the baffle 102. On the side of the baffle 102 facing the tongue 103, a first groove 1021 is provided in the length direction of the baffle. Figure 3 As shown, a spring 104 is provided at the bottom of the first groove, and the spring 104 is connected to the latch 103. When the spring is not compressed, the extended length of the spring just reaches the notch of the first groove. When the spring is compressed, part of the latch is located in the first groove.

[0037] like Figure 3As shown, the tongue 103 includes a tongue tip 1031 and a tongue end 1032, wherein the side of the tongue end 1032 away from the tongue tip 1031 contacts the spring 104, wherein the side of the tongue tip 1031 away from the tongue end 1032 has an arc. In order to maintain a stable state when inserted into the consumable box, the upper surface of the tongue tip 1031 is parallel to the bottom of the consumable box 2, and the lower surface of the tongue tip 1031 forms an acute angle with the upper surface.

[0038] In order to enable the tongue tip 1031 to be inserted into the slot 201 , the depth of the slot 201 is greater than the length d1 of the tongue tip, and the height of the slot 201 is greater than the height d2 of the tongue tip and less than the height d3 of the tongue end.

[0039] like Figure 1 , 4 As shown, the card slot 201 is located on the side of the consumable box 2, and the number of the card slots 201 is two, and the card slots 201 are located on both sides of the bottom of the consumable box. Figure 5 As shown, the cross-section of the consumable box 2 is a trapezoidal structure, the top of the consumable box 2 is a consumable placement rack, and the bottom area of ​​the consumable box 2 is larger than the top area. In this way, when the claw assembly 1 moves from top to bottom, the tongue 103 can gradually retract, and finally when it is close to the bottom slot position of the consumable box, the greater the degree of retraction, when it reaches the slot position, the tongue pops out under the rebound force of the spring, firmly fixes the consumable box, and then the consumable box can move upward through the claw assembly and be lifted to a predetermined position.

[0040] like Figure 5 As shown, the angle between the lower surface of the tongue tip 1031 of the latch and the horizontal direction is A, A is 10-30°, in a preferred embodiment of the present application, A is preferably 15-25°, and in the most preferred embodiment of the present application, A is 20°.

[0041] Working principle: When working, the consumable box is placed flat on the workbench. The synchronous belt starts, driving the left and right claw assemblies to move from top to bottom. When the claw contacts the main body of the consumable box, the tongue will shrink inward due to the slope of the consumable box and the slope design of the tongue. At the same time, the elastic force of the spring acts between the tongue and the main body of the claw to maintain the stability of the consumable box. When the claw assembly moves to the preset slot position, the force of the spring pushes the tongue into the slot to achieve precise positioning of the consumable box. Subsequently, the synchronous belt moves in the opposite direction, driving the claw assembly to move upward, and lifting the consumable box to the predetermined position.

[0042] The feeding mechanism of the present application has a simple structure, convenient operation, good stability of the consumable box during lifting, and can achieve precise positioning. In addition, the feeding mechanism has strong adaptability and can be widely used in feeding operations of consumable boxes of various specifications and sizes.

[0043] The above embodiments are only illustrative of the principles and effects of the present application, and are not intended to limit the present application. Any non-substantial changes to the present application using this concept shall be deemed as an infringement of the protection scope of the present application.
