[0019] like Figure 1-3As shown, a double-station horizontal packaging machine film cutting automatic changeover bagging mechanism comprises a first die-cutting mechanism 1, a second die-cutting mechanism 2 and a bagging mechanism 3. The first die-cutting mechanism 1 and the second die-cutting mechanism 2 are both located at the bottom of the bagging mechanism 3. The bagging mechanism 3 is provided with a cylinder fixing seat 4, a bagging cylinder 8, a first bag gripper cylinder 6, a guide seat 5, a second bag gripper cylinder 7 and a cylinder connecting seat 9. The bagging cylinder 8 is mounted on the upper end of the cylinder fixing seat 4, the second bag gripper cylinder 7 is mounted on the bottom of the cylinder connecting seat 9, the first bag gripper cylinder 6 is mounted on the bottom of the cylinder fixing seat 4, and the cylinder connecting seat 9 is arranged on the outside of the guide seat 5. The second film cutting of the double-station film cutting is used to adjust the position and the bagging distance according to the rigid geometric relationship of the bag size, so that the bagging mechanism can be automatically adjusted following the second film cutting. Only one cylinder is needed to realize this function, which greatly reduces the cost and does not participate in the control of the whole machine, thereby reducing the complexity of control.

[0020] Furthermore, one end of the cylinder fixing seat 4 is positioned on the first die-cutting mechanism 1 , and the guide seat 5 is positioned on the second die-cutting mechanism 2 .

[0021] Furthermore, a push block 13 is connected to the end of the bag-distributing cylinder 8 , a push rod 14 is connected between the push block 13 and the cylinder connecting seat 9 , and a limit block 10 is provided at the front end of the guide seat 5 .

[0022] Furthermore, a first clamping jaw 11 is movably provided at the bottom of the first bag gripper cylinder 6 , and a second clamping jaw 12 is movably provided at the bottom of the second bag gripper cylinder 7 .

[0023] Furthermore, a first die-cutting support plate 15 for die-cutting position limiting is installed on the outer side of the first die-cutting mechanism 1 , and a second die-cutting support plate 16 for die-cutting position limiting is installed on the outer side of the second die-cutting mechanism 2 .

[0024] Furthermore, the guide seat 5 on the bag-distributing mechanism 3 drives the second die-cutting mechanism 2 to move. When the guide seat 5 has a full stroke, the distance between the first die-cutting mechanism 1 and the second die-cutting mechanism 2 reaches 230 mm.

[0025] Working principle: The utility model comprises a first die-cutting mechanism 1, a second die-cutting mechanism 2, a bag-splitting mechanism 3, a cylinder fixing seat 4, a guide seat 5, a first bag gripper cylinder 6, a second bag gripper cylinder 7, a bag-splitting cylinder 8, a cylinder connecting seat 9, a limit block 10, a first clamping jaw 11, a second clamping jaw 12, a push block 13, a push rod 14, a first die-cutting support plate 15, and a second die-cutting support plate 16. The first die-cutting mechanism 1 cuts off the front full-length roll film and the left side of the first bag, and the second die-cutting mechanism 2 cuts off the right side of the first bag and the left side of the second bag. The distance between the right side of the first bag and the left side of the second bag is fixed, which is determined by the mold width of the second die-cutting mechanism 2. In order to adapt to all the subsequent workstations, the second bag needs to be moved to the right to a certain position to ensure that the distance between the left sides of the first bag and the second bag is fixed, and this distance is 230 mm.

[0026] When the width of the bags is different, the distance the second bag needs to move is different. Figure 3 In the example, the large bag needs to move 27.5 and the small bag needs to move 97.5.

[0027] The cylinder fixing seat 4 is fixed together with the first die-cutting mechanism 1, and the guide seat 5 is fixed together with the second die-cutting mechanism 2. When the cylinder connecting seat 9 and the limit block 10 are fitted together, the second bag is at the position of the second die-cutting mechanism 2. The first bag gripper cylinder 6 and the second bag gripper cylinder 7 grab the first bag and the second bag respectively. The first bag does not move, and the second bag moves right with the bag-dividing cylinder 8. When the bag-dividing cylinder 8 has a full stroke, the distance between the first bag and the second bag reaches 230mm. The reason why the bag size can be changed and the bag-dividing mechanism can be automatically adjusted is that the return limit of the cylinder is on the second die-cutting mechanism 2, which is equivalent to the return limit automatically moving with the second die-cutting mechanism 2, and when the cylinder is extended with a full stroke, the position is fixed.

[0028] Taking large and small bags as an example, the difference in bag separation distances is: 97.5-27.5=70, and the difference in the distance of the cylinder limit is: 202.5-132.5=70, so as to realize automatic bag separation by changing the bag type. The second film cutting of the double-station film cutting is used to adjust the position and the bag separation distance according to the size of the bag. The rigid geometric relationship allows the bag separation mechanism to automatically adjust with the second film cutting. This function can be achieved with only one cylinder, which greatly reduces the cost and does not participate in the control of the whole machine, reducing the complexity of control.

[0029] It should be noted that, in this article, relational terms such as first and second (number one, number two), etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "including one..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0030] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
