[0029] In a specific embodiment, Figures 1 to 5As shown, the plug-in plate beam mechanism for bag stacking of the utility model is installed on the bag making main frame 1, located between the material pressing component 9 and the sealing and cutting component 10, and used in conjunction with the finger-clamping type pressing component 11. The plug-in plate beam mechanism for bag stacking of the utility model includes a driving component, a pull arm plate 4, a plug-in plate beam 5, a bronchial tube 6 and a plug-in plate 7. The top of the pull arm plate 4 is connected to the two ends of the horizontally arranged plug-in plate beam 5 by bolts, and the pull arm plate 4 is connected to the outer wall of the bag making main frame 1 through a vertical guide member. The driving component drives the pull arm plate 4 to move up and down in the vertical direction, thereby driving the plug-in plate beam 5. A through-length main air channel 501 is provided at the bottom of the plug-in plate beam 5, one end of the main air channel 501 is connected to an air supply hose, and the other end of the main air channel 501 is made into a threaded hole, and is sealed by a wire plug wrapped with a sealing tape. A plurality of bronchial tubes 6 are arranged vertically at the bottom of the plug-in plate beam 5 and the top end is connected to the main air channel 501. The inserting plate 7 is mounted on the side wall of the inserting plate beam 5 by screws, and the bottom end of the inserting plate 7 is downwardly inserted into the bag to facilitate the stacking of the plastic bags.

[0030] By opening a through-length main air channel 501 at the bottom of the plug-in board beam 5 as the air supply pipeline for each bronchus 6, no additional air pipeline is required, and the weight of the plug-in board beam 5 is reduced; by separating the plug-in board 7 and the plug-in board beam 5, even if the plug-in board 7 is damaged, it is easy to replace it separately. The utility model of the plug-in board beam mechanism for stacking bags has a main air channel horizontally opened on the plug-in board beam, and the root of each bronchus is connected to the main air channel, which avoids additional pipe laying, reduces the weight of moving parts, and reduces the load on the motor.

[0031] It should be pointed out that, as shown in Figures 5 to 6, the description is based on a double-line bag-making machine, that is, it can simultaneously produce and process two continuous conveying lines of plastic bags. Obviously, the board beam mechanism for stacking bags of the utility model can be fully applied to a single-line bag-making machine production line, so the contents shown in the attached drawings shall not be regarded as limiting the scope of protection of the utility model.

[0032] In a specific embodiment of the present invention, Figure 5 The bottom of the plug beam 5 is a downwardly disposed convex block, the main air channel 501 is opened on the convex block and is disposed throughout the entire length, and the top end of the bronchial tube 6 is connected to the bottom surface of the convex block through a threaded hole and is connected to the main air channel 501 .

[0033] Specifically, if Figure 1 , Figure 2 and Figure 5 As shown, a weight-reducing hole 502 is opened at the top of the plug-in plate beam 5 , and the weight-reducing hole 502 is a through hole along the plate thickness direction. A plurality of weight-reducing holes 502 are arranged at equal intervals along the length direction of the plug-in plate beam 5 .

[0034] By setting the bottom of the plug-in plate beam 5 as a downwardly protruding protrusion, it is convenient to install the pipe joint of the air supply hose, while reducing the damage to the overall rigidity of the plug-in plate beam 5; by opening a weight-reducing hole 502 at the top of the plug-in plate beam 5, the weight of the plug-in plate beam 5 can be further reduced.

[0035] In a specific embodiment of the present invention, Figure 2 , Figure 4 and Figure 5 As shown, a plurality of toothed bars 701 are arranged at the bottom of the inserting plate 7, and the corners of the toothed bars 701 are all rounded, and a finger clamp of the pressing assembly 11 is arranged at the gap between two adjacent toothed bars 701. Through the cooperation of the finger clamp and the toothed bars 701, the smooth connection between the tail insertion action and the tail pressing action can be achieved.

[0036] In a specific embodiment of the present invention, Figures 1 to 4 As shown, the driving assembly includes a reduction motor, a driving shaft 2 and a rocker assembly 3. The reduction motor transmits power to the driving shaft 2 through a pulley and a belt, and both ends of the driving shaft 2 are installed on the large side plate of the bag making main frame 1 through a bearing seat. Both ends of the driving shaft 2 protrude from the large side plate and are connected to the arm plate 4 through the rocker assembly 3.

[0037] Specifically, if Figure 3 and Figure 4 As shown, the rocker assembly 3 includes a rocker connected to the end of the driving shaft 2 through a flat key and a connecting rod hinged to the arm plate 4. Every time the rocker rotates one circle, the arm plate 4 completes an up and down reciprocating motion.

[0038] Specifically, if Figure 2 and Figure 4 As shown, the vertical guide member includes a linear guide rail and a ball slider 401, and the inner side of the bottom of the arm plate 4 is guided and slidably connected to the linear guide rail through the ball slider 401. The linear guide rail is vertically fixed on the outer wall of the large side plate of the bag making main frame 1.

[0039] Specifically, if Figures 2 to 4 As shown, the plug-in beam mechanism for bag stacking of the utility model also includes an air spring 8, the number of which is two and they are respectively located under the two pulling arm plates 4, the bottom end of the air spring 8 is fixed to the large side plate of the bag making main frame 1 through a base, and the end of the piston rod of the air spring 8 is hinged with a transfer block, and the transfer block is bolted to the bottom surface of the pulling arm plate 4.

[0040] The two ends of the same driving shaft 2 are used to synchronously drive the arm plate 4 through the rocker assembly 3, ensuring that the two ends of the plugging plate beam 5 move in unison and are not skewed; by adding an air spring 8 under the arm plate 4, the air spring 8 can balance the weight of reciprocating parts such as the arm plate 4, the plugging plate beam 5, the bronchus 6 and the plugging plate 7, thereby reducing the load of the reduction motor.

[0041] In a specific embodiment of the present invention, Figures 1 to 5 As shown, the arm plate 4 and the plate beam 5 are both made of aluminum alloy. The plate 7 is made of carbon fiber plate.

[0042] By using aluminum alloy and carbon fiber plates to make the main components of the utility model, sufficient strength and rigidity can be achieved while reducing the weight of the moving parts as much as possible.

[0043] The working principle of the plug-in board beam mechanism for bag stacking of the utility model is as follows: the compressed clean dry air supply unit of the equipment is connected to the pipe joint at one end of the main air channel 501 through a hose, and the main air channel 501 outputs compressed air to each bronchus 6, and the bronchus 6 sprays compressed air downward to blow the tail of the plastic bag that has just been heat-sealed and cut downward. During the reciprocating movement of the arm plate 4, the air spring 8 contracts and pushes out the piston rod, which can balance the weight of the moving parts and reduce the load of the reduction motor. Regarding the stacking process of the plastic bag film, how the plug-in board 7 performs the action of inserting the bag in a tail-by-tail manner is described in detail in the prior application CN118124202A, and will not be repeated here.

[0044] In summary, by opening a through-length main air channel 501 at the bottom of the plug-in plate beam 5 as the air supply pipeline for each bronchus 6, there is no need to set up an additional air pipeline, which also reduces the weight of the plug-in plate beam 5; by setting the plug-in plate 7 and the plug-in plate beam 5 separately, even if the plug-in plate 7 is damaged, it is convenient to replace it separately. In the utility model, the plug-in plate beam mechanism for stacking bags has a main air channel opened horizontally on the plug-in plate beam, and the roots of each bronchus are connected to the main air channel, which avoids additional pipe laying, reduces the weight of moving parts, and reduces the load on the motor. In addition, by setting the bottom of the plug-in plate beam 5 as a downwardly protruding convex block, it is convenient to install the pipe joint of the air supply hose, while reducing the damage to the overall rigidity of the plug-in plate beam 5; by opening a weight-reducing hole 502 at the top of the plug-in plate beam 5, the weight of the plug-in plate beam 5 can be further reduced. The two ends of the same driving shaft 2 drive the arm plate 4 synchronously through the rocker assembly 3, ensuring that the two ends of the plug-in beam 5 move in unison and are not skewed; by adding an air spring 8 under the arm plate 4, the air spring 8 can balance the weight of the reciprocating parts such as the arm plate 4, the plug-in beam 5, the bronchus 6 and the plug-in plate 7, thereby reducing the load of the reduction motor. By using aluminum alloy and carbon fiber plates to make the main components of the utility model, it can have sufficient strength and rigidity while reducing the weight of the moving parts as much as possible.

If there is no further explanation, it is assumed that the existing technology is used and equipped without special explanation.
