Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical packaging equipment, in particular to an anti-clamping device for a medicine box machine. Background Art

[0002] The aluminum-plastic packaged medicine board is a common form of medicine packaging and is a very important preservation method for maintaining the efficacy stability of medicines. In the prior art, since the aluminum-plastic packaged medicine board usually needs to be further placed in a paper medicine box before the packaging is completed. In the prior art, most of the loading machines are used to load the aluminum-plastic medicine boards into the paper medicine boxes. However, due to the actual problems such as the relatively light weight, certain elasticity and hardness, irregular shape of the aluminum-plastic packaged medicine board, and the feeding capacity of the loading machine, when using the loading machine for automatic packaging, due to the instantaneous thrust, the pressing strip for pressing the medicine box occasionally clamps the edge part of the composite film bag between the pushing head and the pressing strip, and when the pushing head and the pressing strip move back, the medicine will be taken out of the small box, resulting in a stuck box and stopping the line for maintenance, directly affecting the production efficiency. Content of the Utility Model

[0003] Aiming at the deficiencies of the above prior art, the technical problem to be solved by the utility model is: to provide an anti-clamping device for a medicine box machine that can prevent the medicine packaging bag from being clamped.

[0004] To solve the above technical problem, a technical solution adopted by the utility model is: to provide an anti-clamping device for a medicine box machine, which includes a conveying part arranged on the medicine box machine for conveying medicine bags, a placing table arranged on one side of the discharging end of the conveying part for placing medicine boxes, and a pushing part arranged at a position corresponding to the placing table on the other side of the discharging end of the conveying part. The pushing part includes a bracket fixedly arranged on the medicine box machine, a linear motor fixedly arranged on the bracket, and a transmission rod connected to the output end of the linear motor.

The pressing plate is located above the pushing head. On the end face of the extending end of the pushing head, a groove is arranged, and a convex platform is arranged at the upper end of the notch of the groove.

[0005] With the above structure, the pressing plate is arranged to press the composite film bag filled with medicine in the vertical direction, and a convex platform is arranged at the extending end of the pushing head. Before the pushing head touches the composite film bag, the edge of the composite film bag is first pressed, so that the edge of the composite film bag will no longer relatively move to the gap position between the pushing head and the pressing plate, nor form a clamping state with the gap position, avoiding the situation that the composite film bag is taken out of the medicine box when the pushing head and the pressing plate move back and causing the box to be stuck; at the same time, the groove is arranged to enable the edge of the composite film bag to bend downward along the arc of the groove as the pushing head moves, better avoiding the edge of the composite film bag from relatively moving to the gap position between the pushing head and the pressing plate. The structure is compact and practical, and the operation is convenient.

[0006] For the convenience of guiding the bending of the edge of the composite film bag, preferably, an open groove with a "U" - shaped cross - section is provided on the pushing head along the axial direction. A groove is provided on the outer side wall of the open groove corresponding to the end face of the protruding end of the pushing head, and the upper end of the notch of the groove is adjacent to the lower end face of the convex platform.

[0007] For the convenience of replacing the pressing plate, preferably, a horizontally protruding connecting plate is provided on the transmission rod, and a pressing plate is provided at the protruding end of the connecting plate. One side of the pressing plate is screwed to the connecting plate.

[0008] To avoid the appearance of redundant gap positions and prevent the composite film bag from being deformed and embedded under pressure, preferably, the groove wall on one side of the open groove is located directly below the pressing plate, and the upper end face of the groove wall is in close contact with the lower end face of the pressing plate.

[0009] To better avoid the clamping state of the edge of the composite film bag between the pressing plate and the connecting plate after being stressed, preferably, the plane of the end face of the protruding end of the pushing head protrudes from the plane of the end face of the protruding end of the connecting plate.

[0010] Beneficial effects: The convex platform and the pressing plate are provided in the utility model, which can prevent the edge of the composite film bag from being stressed and moving into the gap between the pushing head and the pressing plate, and prevent clamping. At the same time, the provided groove can avoid damaging the composite film bag while guiding and bending the edge of the composite film bag. The structure is simple and compact, and it is convenient to use. Brief Description of the Drawings

[0019] As shown by Figure 1 , Figure 2 and Figure 3 , the utility model includes a conveying part 10 arranged on a medicine box machine (not labeled) for conveying medicine bags, a placing table 11 arranged on one side of the discharging end of the conveying part 10 for placing medicine boxes, and a pushing part arranged at a position corresponding to the placing table 11 on the other side of the discharging end of the conveying part 10. The pushing part includes a bracket 1 fixedly arranged with the medicine box machine, a linear motor 2 fixedly arranged on the bracket 1, and a transmission rod 20 connected to the output end of the linear motor 2. On one side of the transmission rod 20, a horizontally extending push head 3 is arranged, and on the other side, a pressing plate 4 horizontally extending in the same direction as the push head 3 is arranged. The pressing plate 4 is located above the push head 3. On the end face of the extending end of the push head 3, a groove 31 is arranged, and a convex platform 32 is arranged at the upper end of the notch of the groove 31.

[0020] Specifically, an open through groove 33 with a "U" - shaped cross - section is arranged on the push head 3 along the axial direction. On the outer side wall of the open through groove 33 corresponding to the end face of the extending end of the push head 3, a groove 31 is arranged, and the lower end face of the convex platform 32 is adjacent to the upper end of the notch of the groove 31.

[0021] A horizontally extending connecting plate 21 is arranged on the transmission rod 20, and a pressing plate 4 is arranged at the extending end of the connecting plate 21. One side of the pressing plate 4 is screwed on the connecting plate 21.

[0022] One side wall of the open through groove 33 is located directly below the pressing plate 4, and the upper end face of this side wall is in close contact with the lower end face of the pressing plate 4; the plane of the end face of the extending end of the push head 3 protrudes from the plane of the end face of the extending end of the connecting plate 21.

[0023] The working principle of the utility model is as follows:

[0024] As shown in Figures 1 to 3As shown, the conveying part 10 uses a conveyor belt. During use, the composite film bag filled with medicine (not labeled) moves to the position of the pushing part along with the conveying part 10 on the medicine box machine. At this time, the placing table 11 is placed on one side of the discharging end of the conveying part 10, and a linear motor 2 fixed on the bracket 1 is provided at the position corresponding to the placing table 11 on the other side of the discharging end of the conveying part 10. When the linear motor 2 is started, the output end of the linear motor 2 drives the pressing plate 4 and the pushing head 3 to move horizontally towards the composite film bag synchronously. During the movement, the lower end surface of the pressing plate 4 fits the upper end surface of the composite film bag, and the edge position of the composite film bag first contacts the position of the convex platform 32. Since the thickness of the convex platform 32 abuts against the edge position of the composite film bag, the edge position of the composite film bag is pressed and bent downward. Since the upper end of the notch of the groove 31 is adjacent to the lower end surface of the convex platform 32, the bent position extends into the groove along the trend and continues to bend along the groove wall. In this way, the edge position of the composite film bag cannot move to the gap position between the pushing head 3 and the pressing plate 4 in the bent state, let alone form a clamping state with the gap position. Therefore, the pushing head 3 continues to horizontally extend to push the composite film bag into the medicine box. When the pushing head 3 moves in place, then start the linear motor 2 to move back and standby, and the composite film bag will not be clamped out of the medicine box, that is, an operation of pushing the composite film bag into the medicine box is completed.

[0025] Among them, as Figure 1 and Figure 2 shown, the left side wall of the opening through groove 33 is located directly below the pressing plate 4, and the upper end surface of this wall fits and abuts against the lower end surface of the pressing plate 4. During the synchronous movement, there will be no relative movement to cause a misalignment gap, and the possibility of clamping the composite film bag in the gap is also greatly reduced.

[0026] It should be noted that since the edge position of the composite film bag is not fixed, when the convex platform 32 abuts against the edge position of the composite film bag, the edge position of the composite film bag will also be pressed and bent upward. However, since the end surface of the protruding end of the convex platform 32 is a vertical end surface, even if the edge position of the composite film bag is pressed and bent upward towards the gap position between the pushing head 3 and the pressing plate 4, it is in an almost vertical state. Coupled with the thickness dimension of the convex platform 32 itself, it cannot be embedded into the horizontal gap position between the pushing head 3 and the pressing plate 4 along the moving direction, that is, it will not form a clamping state with the gap position.

[0027] In addition, the plane where the end face of the protruding end of the pusher 3 is located protrudes from the plane where the end face of the protruding end of the connecting plate 21 is located. The edge position of the composite film bag always only contacts the boss 32 and the pusher 3. In this way, at the position without the boss 32, the edge position of the composite film bag is not blocked and does not deform or bend, further reducing the probability that the edge position of the composite film bag is embedded in the gap due to forced bending. At the same time, the provided opening groove 33 also reduces the contact area between the edge position of the composite film bag and the pusher 3, reduces the folding range of the edge position of the composite film bag, and further reduces the probability of being embedded in the gap.

[0028] In addition, in order to adapt to the use of composite film bags of various specifications for box loading, the length of the pressing plate 4 also needs to be adjusted accordingly to avoid damaging the medicine box due to extrusion. Therefore, one side of the pressing plate 4 is screwed to the connecting plate 21 for easy disassembly and replacement.
