Description

Technical Field

[0001] The utility model relates to the field of small package machine structures, in particular to a small package machine packaging film releasing mechanism and the small package machine. Background Art

[0002] The small packet machine is actually a packaging machine, specifically a machine for packaging small packets of tissue paper, which has a packaging film releasing mechanism; specifically, the packaging film releasing mechanism includes a mounting seat, a film roll (with a film belt on the film roll) and multiple guide rollers, and the film roll is rotatably connected to the mounting seat to enable the film roll to rotate around its own axis, and in conjunction with the power mechanism for traction of the packaging film, the packaging film on the film roll is released; such as the small packet machine model TPM-70L / R.

[0003] After the packaging film in the previous film roll is released, the film roll needs to be replaced. When replacing the film roll, since the film tape was previously in a taut and stretched state, after the film roll is removed, the film tape instantly changes from a taut state to a relaxed state, and the film tape will shrink, causing the film tape to deviate from the guide roller. Based on the film tape deviating from the guide roller, the machine needs to be stopped and reset when splicing the film, that is, the film tape position needs to be adjusted. This process is more troublesome and can easily cause the film tape position to deviate.

[0004] Therefore, a new solution is needed to solve this technical problem. Utility Model Content

[0005] The purpose of the present invention is to provide a small package machine packaging film release mechanism and a small package machine in response to the above-mentioned problems, which can effectively press the film belt when replacing the film roll, so that the film belt can be kept in a taut and stretched state without stopping the machine to reset, thereby improving the convenience of replacing the film roll.

[0006] The technical solution adopted by the utility model is as follows: a small package machine packaging film release mechanism, including a base, a mounting seat for mounting a film roll, and a plurality of guide rollers fixed on the base, and the plurality of guide rollers are arranged in sequence along the path of movement of the film strip; a clamping mechanism for clamping the film strip is fixed on the base, and the installation position of the clamping mechanism is close to the mounting seat.

[0007] Furthermore, the base is also provided with a film feeding auxiliary component for assisting the film roll to rotate and release the film tape.

[0008] Furthermore, the film feeding auxiliary component includes a rotating motor, an active roller and a driven roller fixedly connected to the base, the active roller is coaxially assembled on the output shaft of the rotating motor, and a belt is tightly stretched between the active roller and the driven roller; after the film roll is installed, the belt can be tightly attached to the surface of the film roll; the active roller and the driven roller are supported by a connecting piece, and the active roller and the driven roller are both rotatably connected to the connecting piece.

[0009] Furthermore, the film delivery auxiliary component is located above the mounting seat.

[0010] Furthermore, the connecting piece is a cover.

[0011] Furthermore, the clamping mechanism comprises a first clamping plate and a second clamping plate, the first clamping plate is fixed on the base, the second clamping plate is fixed on the cover, and the second clamping plate matches the first clamping plate in spatial position so that the second clamping plate can be attached to the first clamping plate.

[0012] Furthermore, the clamping mechanism comprises a fixed magnetic plate and a clamping magnetic plate with magnetic properties, and one end face of the fixed magnetic plate is fixed on the base; when replacing the film roll, the clamping magnetic plate is magnetically connected to the other end face of the fixed magnetic plate, and the film tape is clamped between the clamping magnetic plate and the fixed magnetic plate.

[0013] A small package machine comprises a main body and the small package machine packaging film release mechanism, wherein the base is mounted on the main body; and the main body has a film traction power mechanism, the output end of which can be connected to a film belt to traction the film belt.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0015] The utility model clamps the film tape through the clamping mechanism when replacing the film roll. Under the action of the film traction power mechanism inherent in the small package machine, the film tape can be kept in a taut and stretched state, without the need to stop and reset to adjust the position of the film tape, thereby improving the convenience of replacing the film roll.

[0020] In the description of this specification, it should be noted that if the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, or is the orientation or position relationship in which the product of this specification is usually placed when used. It is only for the convenience of describing this specification and simplifying the description, and does not indicate or imply that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on this specification.

[0021] Furthermore, the use of terms such as "horizontal" and "vertical" in this specification does not necessarily imply that a component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply refers to a direction that is more horizontal than "vertical," and does not imply that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0022] In the description of this specification, it should also be noted that, unless otherwise clearly stipulated and limited, the terms "setting", "installation", "connection" and "connection" should be understood in a broad sense. For example, the connection can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be a connection between the internal parts of two components.

[0023] Example 1

[0024] like Figure 1-Figure 2 As shown, a packaging film release mechanism for a small package machine includes a base 1, on which is fixed a mounting seat 11 for mounting a film roll 12, and a plurality of guide rollers 3, which are arranged in sequence along the movement path of the film strip 4; a clamping mechanism for clamping the film strip 4 is fixed on the base 1; specifically, the film roll 12 can be assembled on the mounting seat 11 in a manner of rotating around its own axis, and the film strip 4 on the film roll 12 is connected to the output end of the film traction power mechanism after passing around the plurality of guide rollers 3, that is, the film traction power mechanism provides power for the film strip 4 to move along the guide rollers 3; when replacing the film roll 12, the film strip 4 is clamped by the clamping mechanism, and under the action of the inherent film traction power mechanism of the small package machine, the film strip 4 can be kept in a taut and stretched state, without the need to stop and reset to adjust the position of the film strip 4, thereby improving the convenience of replacing the film roll 12.

[0025] In this embodiment, the installation position of the clamping mechanism is close to the mounting seat 11, so that the clamping position of the film strip 4 is close to the mounting seat 11, reducing the amount of loose film strip 4 between the mounting seat 11 and the guide roller 3, and ensuring that the position of the film strip 4 on more guide rollers 3 will not be offset.

[0026] In this embodiment, the mounting base 11, the guide roller 3 and the film traction power mechanism are all existing structures, so their specific structures do not need to be described in detail in this specification.

[0027] Example 2

[0028] Based on Example 1, a feasible specific implementation method is further proposed.

[0029] The base 1 is also provided with a film feeding auxiliary component, which is used to assist the film roll 12 in rotating so that the film roll 12 actively releases the film strip 4 and cooperates with the film traction power mechanism to reduce the pulling force on the film strip 4 and further reduce the risk of the film strip 4 being broken.

[0030] Specifically, the film feeding auxiliary component includes a rotating motor, an active roller 6 and a driven roller 8 fixedly connected to the base 1. The active roller 6 is coaxially assembled on the output shaft of the rotating motor, that is, the rotating motor drives the active roller 6 to rotate around its own axis; a belt 9 is tightly stretched between the active roller 6 and the driven roller 8, and the rotation of the active roller 6 drives the driven roller 8 to rotate through the belt 9, thereby realizing the circular motion of the belt 9; after the film roll 12 is installed, the belt 9 can be tightly attached to the surface of the film roll 12, and the movement of the belt 9 drives the film roll 12 to rotate in the direction of releasing the film tape 4, thereby realizing the film roll 12 actively releasing the film tape 4; the active roller 6 and the driven roller 8 are supported by the connecting member 7 to support the driven roller 8, and the active roller 6 and the driven roller 8 are both rotatably connected to the connecting member 7 to ensure that the active roller 6 and the driven roller 8 can rotate stably.

[0031] It should be noted that, as can be seen from the above, the connecting member 7 can rotate around the active roller 6, that is, rotating the connecting member 7 can realize the film feeding auxiliary component (belt 9) away from the film roll 12 on the mounting seat 11, that is, the belt 9 is no longer close to the film roll 12, and further the film roll 12 can be replaced.

[0032] In a feasible implementation manner, the film feeding auxiliary component is located above the mounting seat 11, and the mating connector 7 is capable of rotating around the active roller 6. The film feeding auxiliary component can utilize its own weight to maintain a close contact with the film roll 12.

[0033] In a feasible implementation manner, the connecting member 7 is a cover to achieve the purpose of protecting the belt 9.

[0034] A feasible implementation method is that the base 1 is "L"-shaped, and the film delivery auxiliary component can be kept in a state by leaning the cover against the base 1 after it moves away from the mounting seat 11, without the need for manual continuous holding of the film delivery auxiliary component; for this purpose, a motor mounting seat 11 can be installed on the base 1, so that the base 1, the motor mounting seat 11 and the cover can form a triangular stable structure.

[0035] Example 3

[0036] Based on any one of the implementations in Example 1 or 2, a specific implementation of the "clamping mechanism" is further proposed.

[0037] The first embodiment, based on Example 2, the clamping mechanism is a first clamping plate 5 and a second clamping plate 10, the first clamping plate 5 is fixed on the base 1, the second clamping plate 10 is fixed on the cover, and the second clamping plate 10 matches the first clamping plate 5 in spatial position so that the second clamping plate 10 can be attached to the first clamping plate 5, and when the cover relies on the base 1 to keep the film feeding auxiliary component away from the mounting seat 11, the second clamping plate 10 and the first clamping plate 5 will clamp the film strip 4.

[0038] In the second embodiment, the clamping mechanism comprises a fixed magnetic plate and a clamping magnetic plate with magnetic properties, and one end face of the fixed magnetic plate is fixed on the base 1; when replacing the film roll 12, the clamping magnetic plate is magnetically connected to the other end face of the fixed magnetic plate, and the film strip 4 is clamped between the clamping magnetic plate and the fixed magnetic plate, and the magnetic force between the clamping magnetic plate and the fixed magnetic plate is used to clamp the film strip 4.

[0039] Example 4

[0040] A small package machine includes a main body and a small package machine packaging film release mechanism as described in any one of the embodiments 1-3, and a base 1 is installed on the main body; and the main body has a film traction power mechanism, the output end of the film traction power mechanism can be connected to the film belt 4 to pull the film belt 4; the main body is known to those skilled in the art and will not be described here; the small package machine is combined with a small package machine packaging film release mechanism with a clamping mechanism, which can keep the film belt 4 in a taut and stretched state without stopping and resetting to adjust the position of the film belt 4, thereby improving the convenience of replacing the film roll 12.

[0041] The present invention is not limited to the aforementioned specific embodiments, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
