[0029] Please refer to Figures 1-5 The embodiment of the present application discloses a film providing and pulling device 100.

[0030] In an embodiment, as shown in Figures 1-5 The film providing and pulling device 100 includes a film providing and sealing cutting mechanism 10 for providing a folded double-layer film 200 of different specifications and cutting the double-layer film 200 and sealing the edges to make a film bag, and a film pulling mechanism 20 arranged on the film providing and sealing cutting mechanism 10 for pulling the double-layer film 200 of different specifications from a film outlet 104.

[0031] The film supply sealing and cutting mechanism 10 comprises a fifth driving member 108, a first fixed plate 109, a fixed frame 101, a first film outlet plate 102 and a second film outlet plate 103. The fixed frame 101 is perpendicular to the ground. The second film outlet plate 103 is horizontally arranged on the fixed frame 101. The first fixed plate 109 is horizontally arranged on the fixed frame 101. One end of the fifth driving member 108 is fixed to the first film outlet plate 102. The other end of the fifth driving member 108 is fixed to the first fixed plate 109. The second film outlet plate 103 is fixed. The fifth driving member 108 drives the first film outlet plate 102 to move towards or away from the second film outlet plate 103. After the second film outlet plate 103 moves towards the first film outlet plate 102, a film outlet channel is formed between the first film outlet plate 102 and the second film outlet plate 103. In addition, a film outlet 104 is formed, and the film outlet channel and the film outlet 104 are communicated, so that the double-layer film 200 can pass through the first film outlet plate 102 and the second film outlet plate 103. After the film is supplied, the first film outlet plate 102 and the second film outlet plate 103 maintain a certain gap. The gap can ensure that the double-layer film 200 can pass through, and can also ensure that the double-layer film 200 has a certain pressure, so as to avoid that the film is retracted. The double-layer film 200 is fixed in the form of a roll on one end of the fixed frame 101 of the film supply sealing and cutting mechanism 10 close to the ground, so as to avoid that the heavy roll is placed on the top of the fixed frame 101, which causes the film supply and film pulling device 100 to fall.

[0032] For example, the fifth driving member 108 can be a motor or a cylinder driver. In this embodiment, the fifth driving member 108 is preferably a motor.

[0033] The film pulling mechanism 20 is arranged on the fixed frame 101 and is located on the same side of the roll as the roll. The film pulling mechanism 20 is located above the roll, which greatly utilizes the effective space, so that the structure design of the film supply and film pulling device 100 is compact and small in size.

[0034] The film pulling mechanism 20 comprises a driving assembly 21 and a clamping assembly 22. One end of the driving assembly 21 is arranged on the fixed frame 101, and the other end of the driving assembly 21 is arranged on the clamping assembly 22. The driving assembly 21 is used to drive the clamping assembly 22 to approach the film outlet 104 or drive the clamping assembly 22 to move away from the film outlet 104, so that the clamping assembly 22 can be moved to clamp the double-layer film 200 at the film outlet 104, and then the double-layer film 200 is pulled out from the film outlet 104 by a predetermined length to complete the film pulling. The clamping assembly 22 comprises a first clamping plate 221 and a second clamping plate 222. The second clamping plate 222 is arranged opposite to the first clamping plate 221. The first clamping plate 221 and the second clamping plate 222 form a clamping opening 225. The first clamping plate 221 and the second clamping plate 222 can be opened and closed. Therefore, when the first clamping plate 221 and the second clamping plate 222 approach each other (i.e., when the first clamping plate 221 and the second clamping plate 222 are closed), the double-layer film 200 can be clamped. When the film is clamped, the driving assembly 21 drives the first clamping plate 221 and the second clamping plate 222 to move together towards the film outlet 104 until the first clamping plate 221 and the second clamping plate 222 approach the film outlet 104. The first clamping plate 221 and the second clamping plate 222 clamp the double-layer film 200. The driving assembly 21 reverses to drive the first clamping plate 221 and the second clamping plate 222 to move away from the film outlet 104, so that the double-layer film 200 is pulled out. The length of the double-layer film 200 can be pulled out according to actual conditions. The length of the clamping opening 225 is greater than the width of the double-layer film 200 with the largest specification. The first clamping plate 221 and the second clamping plate 222 are in the form of a long strip plate structure, so that the clamping assembly 22 can clamp double-layer films 200 of various specifications, has strong versatility, and can arbitrarily switch double-layer films 200 of different specifications when clamping double-layer films 200 of different specifications, thereby improving production efficiency. The first clamping plate 221 and the second clamping plate 222 can clamp double-layer films 200 of various specifications through cooperation, without the need to additionally increase an adjusting mechanism for manually adjusting the distance, so that the film supply and film pulling device 100 has simple structure, convenient operation and small size.

One end of the guide column 29 is arranged on the second clamping plate 222, and the other end of the guide column 29 is arranged on the second fixed plate 24 through the guide plate 27. The guide column 29 guides the movement of the second driving member 31 driving the second clamping plate 222. One end of the third driving member 31 is arranged on the second fixed plate 24, and the other end of the third driving member 31 is arranged on the second fixed plate 24 through the guide plate 27. The second driving member 30 and the third driving member 31 can simultaneously drive the first clamping plate 221 and the second clamping plate 222 to move close to or away from each other.

[0042] For example, the second driving member 30 and the third driving member 31 can be motors or air cylinders.

[0043] In an embodiment, as shown, Figure 3 The film pulling mechanism 20 further comprises a hook plate 32 and a connecting member 33.

[0045] In an embodiment, as shown in Figure 4 and Figure 5 The film cutting and sealing mechanism 10 further comprises a plurality of rollers 105, each of which is rotatably arranged on the fixed frame 101, and the plurality of rollers 105 jointly define a conveying path, which is in communication with the film outlet channel, so that when the roll is pulled open according to the predetermined specification through the rollers 105, it can pass through the film outlet channel and directly reach the film outlet 104.

[0046] Since the double-sided film has only one side as a folding edge and the other three sides as open edges, after the first double-sided film is heat cut, it is directly discarded. Since the first double-sided film is heat cut and sealed at the same time, the other double-sided film on the other side of the first double-sided film is also heat cut and sealed, so that the clamped end of the second double-sided film pulled out is a closed end. Therefore, the second double-sided film only needs to be pulled to a predetermined length to be heat cut and sealed again to form a three-edge sealed film bag, and the side opposite to the folding edge is an open film bag. The opening is directed towards the hook head of the hook plate, so that the hook plate can hook the film bag, facilitating the subsequent bag moving mechanism.

[0047] When pulling the film, first manually pull the double-sided film on the roll through the plurality of rollers to the film outlet, then the first driving member drives the clamping assembly to move towards the film outlet direction until it is inserted into the film outlet, and the second driving member and the third driving member simultaneously drive the first clamping plate and the second clamping plate to move towards each other and clamp the double-sided film. After clamping, the first driving member drives the clamping assembly to move away from the film outlet, so that the double-sided film is pulled out. Since the length of the clamping gap formed by the first clamping plate and the second clamping plate is greater than the width of the largest specification double-sided film, and the first clamping plate and the second clamping plate are long strip-shaped plate structures, the clamping assembly can clamp double-sided films of various specifications, has strong versatility, and can arbitrarily switch double-sided films of different specifications by adjusting the clamping distance between the clamping assemblies when clamping double-sided films of different specifications, thereby improving production efficiency. By cooperating the first clamping plate and the second clamping plate, various double-sided films of different specifications can be clamped without the need for additional manual adjustment mechanism to adjust the distance, so that the film pulling device has simple structure, convenient operation and small size.

[0048] The above examples are only used to illustrate the technical solutions of the present application, and are not limited thereto; under the concept of the present application, the technical features in the above examples or different examples can also be combined, the steps can be implemented in any order, and there are many other changes of different aspects of the present application as described above, which are not provided in details for simplicity; although the present application has been described in detail with reference to the foregoing examples, it should be understood by those skilled in the art that the technical solutions recorded in the foregoing examples can still be modified, or some technical features therein can be replaced equivalently; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
