Description

Technical Field

[0001] The utility model relates to a blister plate cartoning machine, in particular to a material pushing mechanism of the blister plate cartoning machine. Background Art

[0002] A blister plate cartoning machine is a device that loads blister plates (such as capsule medicine plates) and paper instructions into medicine boxes. For example, the applicant applied for an invention patent named "Pushing device for blister plate cartoning machine" in 2019 (CN111017303A). The pushing device of the blister plate cartoning machine includes a chain, a sprocket, an annular push plate guide rail, and a plurality of pushing units. The pushing unit includes a pushing seat, a pushing plate assembly, and a paper pushing assembly. The pushing unit is connected to the chain through its pushing seat. The sprocket drives the chain to rotate through the transmission of the main power source. The pushing unit moves along a circular trajectory driven by the sprocket, and the push plate assembly pushes the medicine plate M into the medicine box under the guidance of the annular push plate guide rail, and the paper pushing assembly pushes the instructions P into the medicine box under the guidance of the annular paper pushing guide rail. Figure 7 As shown, the paper pushing head of the existing paper pushing assembly and the plate pushing head of the plate pushing assembly only move forward to push the material. However, during the pushing process, the front end of the medicine plate M will be subject to resistance from the instruction manual and the paper box (the instruction manual will be subject to resistance from the paper box when entering the paper box, so the instruction manual will also form resistance to the medicine plate M). The medicine plate M may bend, affecting the appearance of the medicine plate M and even making it impossible to pack the medicine plate M normally. Summary of the invention

[0016] like Figure 1 As shown, the pushing mechanism C of the cartoning machine is driven by a synchronous belt A or a chain and guided by an annular pushing guide rail B to push the instruction sheet P and the medicine plate M into the medicine box.

[0017] like Figure 2 As shown, the pushing mechanism C of the cartoning machine includes a pushing movable seat 1, a paper pushing assembly and a pushing plate assembly; Figure 6As shown, the paper pushing assembly includes a paper pushing seat 32, a paper pushing head 3 and a paper pushing roller 34. The paper pushing head 3 and the paper pushing roller 34 are both installed on the paper pushing seat 32. The paper pushing seat 32 can be slidably arranged on the material pushing movable seat 1; Figure 5 As shown, the push plate assembly includes a push plate seat 20, a push plate head 2 and a push plate roller 22. The push plate head 2 and the push plate roller 22 are both mounted on the push plate seat 20. The push plate seat 20 can be slidably arranged on the push material moving seat 1. In order to enable the paper push head 3 to move forward and have a downward movement, the paper push head 3 is connected to the swing rod 30, as shown in FIG. Figure 6 As shown, the swing rod 30 is hinged to one end of two connecting arms 31, and the other ends of the two connecting arms 31 are hinged to the paper pushing seat 32. The two connecting arms 31 are arranged one in front of the other. Due to the quadrilateral structure, the swing rod 30 can always remain horizontal when moving up and down. In addition, a guide wheel 38 is connected to the swing rod 30, and a guide plate 4 is provided on the pushing material moving seat 1. The guide plate 4 has a guide groove 40. The guide wheel 38 is located in the guide groove 40, and the guide groove 40 has a guide path for the guide wheel 38 to move forward and gradually downward.

[0018] The working principle of the pushing mechanism C of the cartoning machine is as follows: Figure 7 As shown, the push plate movable seat 1 moves driven by the synchronous belt A or the chain, and the push plate roller 22 of the push plate assembly and the paper pushing roller 34 of the paper pushing assembly move under the guidance of the annular push plate guide rail B, so that the push plate seat 20 of the push plate assembly is moved on the push plate movable seat 1, and drives the push plate head 2 to push the medicine board M forward; at the same time, the paper pushing seat 32 of the paper pushing assembly moves on the push plate movable seat 1, and drives the paper pushing head 3 to push the instruction manual P forward; when the paper pushing seat 32 moves forward, the swing arm 30 also moves forward, so that the guide wheel 38 on the swing arm 30 moves in the guide groove 40. Since the guide groove 40 has a guide path for the guide wheel 38 to move forward and gradually downward, the swing arm 30 gradually moves downward, so that the paper pushing head 3 is pressed down on the medicine board M, so that the medicine board M will not bend when it is pushed forward by the push plate head 2, thereby ensuring that the shape of the medicine board M is not deformed.

[0019] In order to realize the quick disassembly of the paper pusher 3, as Figure 4As shown, the paper pusher 3 is connected to the quick release seat 36, and the quick release seat 36 is plugged into the swing rod 30. A locking member 35 is hinged on the swing rod 30. One end of the locking member 35 has a locking portion, and the quick release seat 36 has a locking groove. The swing rod 30 is provided with a spring 37 for driving the locking member 35 to rotate. The spring 37 can make the locking portion of the locking member 35 stuck in the locking groove of the quick release seat 36. When the paper pusher 3 needs to be installed, the locking member 35 is pressed by hand to compress the spring 37, and then the quick release seat 36 is plugged into the swing rod 30, and the hand is released to make the locking portion of the locking member 35 stuck in the locking groove of the quick release seat 36, so that the installation is completed; when it needs to be removed, it is only necessary to press the locking member 35 to make the locking portion of the locking member 35 disengage from the locking groove of the quick release seat 36, which is very convenient and quick.

[0020] In order to allow the push plate seat 20 and the paper push seat 32 to slide on the material push moving seat 1, as shown in FIG. Figure 3 As shown, the pusher movable seat 1 includes two parallel guide shafts 10 on the left and right. Figure 2 and Figure 3 As shown, a paper pushing sleeve 33 is provided on the paper pushing seat 32, and a push plate sleeve 21 is provided on the push plate seat 20, and both the paper pushing sleeve 33 and the push plate sleeve 21 are slidably provided on two guide shafts 10. Of course, the push plate seat 20 and the paper pushing seat 32 can also be moved on the material pushing movable seat 1 by using a common guide rail.

[0021] like Figure 2 As shown, the guide groove 40 is composed of an upper horizontal section, an oblique section and a lower horizontal section in sequence. In this way, the paper pusher 3 can move forward first, then gradually move downward, and finally move forward. This movement mode can make the paper pusher 3 move forward while pressing downward more gently, ensuring the stability of the movement of the paper pusher 3, so that the paper pusher 3 has no impact vibration during operation, and reduces noise.
