Technical Field

[0001] The utility model relates to the technical field of filter element processing equipment, in particular to a die pressing device for preparing an air filter element. Background Art

[0002] The filter element of the air filter is a key component used to capture impurities such as particulate matter, dust, pollen, bacteria, viruses, etc. in the air. The design and material selection of the filter element directly affect the performance of the filter, and the filter element needs to be cut, wound, folded, pressed and bonded during the processing. In particular, it needs to be pressed into shape during the pressing process. The effect of the pressing determines the filtering effect of the finished filter element.

[0003] However, the existing air filter element pressing device only presses the filter element through a pressing plate, which easily leads to a loose structure of the filter element during the pressing process, making it difficult to form a tight and stable structure, affecting the filtering effect of the finished product, and it is difficult to form automatic material unloading during the pressing process, which greatly affects the overall processing efficiency;

[0004] In view of the above technical defects, a solution is now proposed. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the pressing die device of the air filter element in the prior art cannot ensure the stability of the filter element structure during processing and cannot automatically unload the material during the processing, and to propose a pressing die device for preparing the air filter element.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a die pressing device for preparing an air filter element, comprising a workbench, two baffles are symmetrically fixed at the front and rear ends of the upper surface of the workbench, a conveyor belt is rotatably connected between the two baffles, a plurality of molds are equidistantly fixed on the upper surface of the conveyor belt, a second support frame is commonly fixed on one side of the top ends of the two baffles, the upper surface of the second support frame is fixed to a hydraulic pump, and a driving end of the hydraulic pump penetrates and extends to the inside of the second support frame, where a die pressing mechanism is installed;

[0007] The cam frame is an axially movable frame having two movable plates connected thereto in a symmetrical manner at the front and rear ends of the cam frame. The top end of the movable plate passes through and extends to a first guide slider fixed inside the top end of the cam frame. A guide through groove is provided inside the top end of the cam frame at a position corresponding to the first guide slider. A guide slide rod is passed through and connected to the inside of the first guide slider, and a first spring sleeved on the outer layer of the guide slide rod is fixed to one side of the first guide slider.

The top end of the first connecting rod passes through and extends to the outside of the cam frame and is rotatably connected to a connecting block. The top ends of the two connecting blocks are fixed to the bottom of the lifting plate.

[0008] Furthermore, a first support frame is commonly fixed to the other side of the top ends of the two baffles, a material storage box is fixed to the upper surface of the first support frame, one side of the material storage box is provided with a discharge port opened on the upper surface of the first support frame, and the other side of the material storage box is provided with a fixed box fixed to the upper surface of the first support frame.

[0026] When the mold 9 moves to the bottom of the die pressing mechanism 3, the hydraulic pump 10 is started to drive the lifting plate 14 to move downward, and the lifting plate 14 moves downward to drive the die frame 16 to move downward until it contacts the filter element. As the lifting plate 14 continues to descend, the connecting block 22 descends and drives the top of the first connecting rod 17 to descend.

[0030] A second guide slider 13 that penetrates and extends to the interior of the upper surface of the first support frame 2 is fixed at the bottom of the limit plate 24. A guide slot 29 is provided at a position on the upper surface of the first support frame 2 corresponding to the second guide slider 13.

[0032] Working process and principle of this utility model:

[0033] Step 1: When the mold 9 moves to the bottom of the discharge port 7, the first motor 5 is started to drive the cam 23 to rotate. The rotation of the cam 23 forms an intermittent push on the limit plate 24, and cooperates with the reset effect of the second spring 25, thereby driving the limit plate 24 to form a reciprocating motion. The limit plate 24 is double-limited and reciprocated by the second guide slider 13 and the guide slide groove 29, and the limit groove 28 and the limit block 30, thereby driving the second connecting rod 26 to reciprocate, and finally the filter element is pushed to the inside of the discharge port 7 by the push plate 27 to form an intermittent automatic discharge effect;

[0034] Step 2: When the mold 9 moves to the bottom of the die pressing mechanism 3, the hydraulic pump 10 is started to drive the lifting plate 14 to move downward. The lifting plate 14 moves downward and drives the die frame 16 to move downward until it contacts the filter element. As the lifting plate 14 continues to descend, the connecting block 22 descends and drives the top of the first connecting rod 17 to descend. The top of the first connecting rod 17 descends and drives the bottom of the first connecting rod 17 to move toward the middle position of the guide groove 18, thereby driving the first guide slider 21 to move toward the middle position of the guide groove 18, and then drives the moving plate 15 to move to squeeze the filter element, making its overall structure tighter. After the die pressing is completed, the first guide slider 21 is subjected to the rebound force of the first spring 19 and drives the moving plate 15 to reset.
