Detailed Implementation

[0019] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0020] In this utility model, unless otherwise stated, directional terms such as "up, down, left, right, front, back, inside, outside" in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as a limitation on the term.

[0021] See Figure 1-4 The reciprocating feeding mechanism shown includes a base plate 1 and first side plates 9 disposed on both sides of the base plate 1. A second side plate 2 with a lower height than the first side plate 9 is disposed on the inner side of the first side plate 9. An upper sliding plate 12 is installed on the two first side plates 9, and a lower sliding plate 4 is installed on the two second side plates 2. A first fixture 15 is installed on the upper sliding plate 12, and a second fixture 7 is installed on the lower sliding plate 4 through a lifting mechanism.

[0022] By implementing the above technical solution, the upper sliding plate 12 drives the first fixture 15 to move back and forth, enabling one-time loading. After the first loading is completed, during the transport to the processing end, the lower sliding plate 4 carries the second fixture 7 to the loading end for a second loading. To avoid affecting the first fixture 15 during the movement of the second fixture 7, a lifting mechanism is set to lower the height of the second fixture 7. The lifting mechanism is only used at the loading end and the processing end to raise the second fixture 7 to its normal height. After the product on the first fixture 15 is unloaded, the first fixture 15 moves to the loading end, and then the second fixture 7 carries the material to the processing end for unloading. This operation is repeated to achieve reciprocating loading of the first and second loading, reducing waiting time and effectively improving loading efficiency compared to single fixture loading.

[0023] In this embodiment, to further provide a driving force for pushing the upper sliding plate 12, a first rodless cylinder is installed on the outer side of the first side plate 9. The first rodless cylinder is connected to the end of the upper sliding plate 12 via a connecting plate 14. A first slider 21 is provided at the bottom of the upper sliding plate 12, and a first slide rail 11 that slides in cooperation with the first slider 21 is provided at the top of the first side plate 9. The two ends of the inner shaft of the first rodless cylinder are installed on the outer side of the first side plate 9 via angle plates. The cylinder body reciprocates under the guidance of the inner shaft, thereby driving the upper sliding plate 12 connected to it to move back and forth.

[0024] In this embodiment, the lifting mechanism includes two symmetrically arranged lifting cylinders 6, and guide rods 8 are provided at the four corners of the second fixture 7. The guide rods 8 are slidably engaged with bushings provided on the lower sliding plate 4. With this arrangement, the second fixture 7 can move vertically up and down by extending and retracting the lifting cylinders 6 and under the guidance of the four guide rods 8.

[0025] In this embodiment, a horizontal plate 24 is mounted on the middle of the base plate 1 via multiple vertical plates 5 arranged in a front-to-back pattern. End plates 17 are provided at both ends of the horizontal plate 24, and a second rodless cylinder connected to the lower sliding plate 4 is installed between two end plates 17. With this arrangement, the inner shaft of the second rodless cylinder is mounted on the end plates 17, and the cylinder body reciprocates under the guidance of the inner shaft, thereby driving the lower sliding plate 4 connected to it to move back and forth.

[0026] In this embodiment, in order to increase the operational stability of the second rodless cylinder and the buffering performance at both ends of the cylinder body, a first limiting buffer 18 is installed on the end plate 17, and a guide rod 20 is provided between the two end plates 17 on both sides of the second rodless cylinder, and the guide rod 20 slides with the second rodless cylinder.

[0027] In this embodiment, second sliders 23 are installed at the bottom of both ends of the lower sliding plate 4, and a second slide rail 3 is provided on the top of the second side plate 2 to slide in cooperation with the second sliders 23. This arrangement allows the lower sliding plate 4 to slide stably in the front-back direction.

[0028] In this embodiment, a second limiting buffer 19 is mounted on the lower sliding plate 4 via a gantry frame 10. The second limiting buffer 19 buffers and limits the downward movement of the second fixture 7.

[0029] In this embodiment, third limiting buffers 16 that cooperate with the upper sliding plate 12 are installed at both ends of the first side plate 9. The third limiting buffers 16, in cooperation with the upper sliding plate 12, buffer and limit the forward and backward sliding position of the upper sliding plate 12.

[0030] In the first fixture 15 and the second fixture 7 of this utility model, multiple positioning posts corresponding to the product and U-shaped elastic clamps are provided for better fixing of the product.

[0031] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0032] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
