Technical Field

[0001] This utility model relates to the field of tobacco machinery technology, and in particular to a film removal clamp and film removal device. Background Technology

[0002] During the cigarette manufacturing process, tobacco additives need to be transported to the manufacturing workshop. To facilitate the transportation of tobacco additives and prevent them from getting damp, a thin film is usually wrapped around the outside of the tobacco additive packaging. When using the tobacco additives, the outer film of the tobacco additive packaging is removed.

[0003] Existing technologies use film removal clamps to remove the film. Specifically, the film is cut by slicing it open with a cutting blade. However, this method suffers from difficulty in controlling the cutting depth, which can damage the tobacco packaging. Furthermore, after cutting the film, existing technologies use a gripping mechanism to detach it from the tobacco packaging material. However, this gripping mechanism is complex and costly. Utility Model Content

[0004] The purpose of this utility model is to provide a film removal clamp and film removal device that can prevent tobacco auxiliary materials from being cut. The overall structure is simple and compact, the cost is low, and the degree of integration is high.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] On the one hand, a film removal clamp is provided, comprising:

[0007] Base;

[0008] A cutting mechanism includes a film hook and a cutting component. The film hook is connected to the base and can extend between the film and the product, allowing the film to cover the top surface of the film hook.

[0009] The clamping mechanism includes a drive member, a first clamping member, and a second clamping member. The drive member is connected to the base, the first clamping member is fixed to the base, and the second clamping member is connected to the output end of the drive member. The drive member is used to drive the second clamping member to move so that the second clamping member moves closer to or away from the first clamping member, so as to clamp or release the film.

[0010] In some possible implementations, the front end of the hook-shaped member is provided with a sharp corner.

[0011] In some possible implementations, the cutting mechanism further includes a buffer assembly comprising a fixed base, a guide member, and an elastic member. The fixed base is fixed to the base and has a guide hole. One end of the guide member is fixed to the hook member, and the other end of the guide member passes through the guide hole and is slidably connected to the guide hole. The elastic member is disposed between the hook member and the fixed base.

[0012] In some possible implementations, the buffer assembly further includes a collision avoidance sensor and a trigger, the collision avoidance sensor being fixed to the base and configured to communicate with the moving mechanism, and the trigger being fixed to the guide for triggering the collision avoidance sensor.

[0013] In some possible implementations, the cutting element is a high-frequency vibrating knife, and the top of the hook-shaped element is provided with a knife-avoiding groove.

[0014] In some possible implementations, the first clamping member includes a fixing part and a clamping part, the fixing part being fixed to the base and the clamping part being inclined relative to the base.

[0015] In some possible implementations, the second clamping member is rotatably connected to the base, and the output end of the driving member is connected to the second clamping member to drive the second clamping member to swing.

[0018] The film removal clamp further includes a distance sensor fixed to the base for detecting the distance between the base and the product, and the distance sensor is configured to communicate with the moving mechanism; and / or,

[0019] Both the first clamping member and the second clamping member are provided with soft rubber pads.

[0020] On the other hand, a film removal device is provided, including a moving mechanism and a film removal clamp as described in any of the above embodiments, wherein the output end of the moving mechanism is connected to a base.

[0021] The beneficial effects of this utility model are:

[0022] This utility model provides a film removal clamp, comprising a base, a cutting mechanism, and a clamping mechanism. During film cutting, a hook-shaped component extends between the film and the product to separate them, while the cutting component cuts the film covering the hook-shaped component.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0035] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0036] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0037] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0038] like Figures 1 to 5As shown, this utility model provides a film removal clamp, which is suitable for removing the outer film of various tobacco auxiliary materials. Through two major actions, cutting the film and clamping the film, the cutting operation of the film 100 and the collection operation of the cut film 100 are completed. The film removal fixture includes a base 1, a cutting mechanism 2, and a clamping mechanism 3. The cutting mechanism 2 includes a film hook 21 and a cutting component 22. The film hook 21 is connected to the base 1 and can extend between the film 100 and the product 200, allowing the film 100 to cover the top surface of the film hook 21. The cutting component 22 is connected to the base 1 and is used to cut the film 100 covering the film hook 21. The clamping mechanism 3 includes a driving component 31, a first clamping component 32, and a second clamping component 33. The driving component 31 is connected to the base 1, the first clamping component 32 is fixed to the base 1, and the second clamping component 33 is connected to the output end of the driving component 31. The driving component 31 is used to drive the second clamping component 33 to move so that the second clamping component 33 moves closer to or away from the first clamping component 32, thereby clamping or releasing the film 100. When cutting the film 100, the hook member 21 extends between the film 100 and the product 200 to separate them, and the cutting member 22 cuts the film 100 covering the hook member 21. By setting the hook member 21, the tobacco auxiliary material, i.e., the product 200, is prevented from being cut by the cutting member 22. When removing the film 100, the film 100 is cut by the cutting member 22. After cutting, the driving member 31 drives the second clamping member 33 to move, so that the second clamping member 33 moves close to the first clamping member 32 to clamp the film 100, making it easier to peel the film 100 off the product 200 later. The cutting mechanism 2 and the clamping mechanism 3 of this utility model have a simple and compact structure, occupy little space, and have low cost. In addition, the integration of the cutting mechanism 2 and the clamping mechanism 3 improves the degree of integration.

[0039] Optionally, the front end of the film hooking member 21 is provided with a pointed corner 211. By providing the pointed corner 211, it is convenient for the film hooking member 21 to hook the film 100 from the product 200 and to position the film hooking member 21 between the film 100 and the product 200.

[0040] Optionally, the cutting mechanism 2 further includes a buffer assembly, which includes a fixed base 231, a guide member 232, and an elastic member 233. The fixed base 231 is fixed to the base 1 and has a guide hole. One end of the guide member 232 is fixed to the hook member 21, and the other end of the guide member 232 passes through the guide hole and is slidably connected to the guide hole. The elastic member 233 is disposed between the hook member 21 and the fixed base 231. Specifically, the fixed base 231 includes a seat body and a guide sleeve 2311. The guide sleeve 2311 passes through the seat body, and the guide hole is located in the guide sleeve 2311. By setting the buffer assembly, when the hook member 21 approaches the product 200, the guide member 232 floats up and down within the fixed base 231 to prevent the hook member 21 from hitting the product 200, wherein the elastic member 233 provides the floating force. Furthermore, the buffer assembly can also provide a certain degree of adaptation to unevenness. When the film hook 21 extends between the film 100 and the product 200, it ensures that the bottom of the film hook 21 is always in contact with the product 200, so as to smoothly hook the film and enable the film hook 21 to stably complete the hooking and insertion functions.

[0041] In this embodiment, the elastic element 233 is a spring, which is sleeved on the guide element 232. One end of the spring abuts against the hook element 21, and the other end abuts against the fixed seat 231. This arrangement simplifies the structure of the buffer assembly, facilitates installation, and saves space. The guide element 232 guides the compression of the spring. Of course, in other embodiments, the spring may not be sleeved on the guide element 232; one end of the spring may be fixedly connected to the hook element 21, and the other end may be fixedly connected to the fixed seat 231. Furthermore, in this embodiment, to ensure the balance of force, two guide elements 232 are spaced apart from the hook element 21, and two guide holes are correspondingly provided for the two guide elements 232. Each guide element 232 is sleeved with a spring.

[0042] Optionally, the buffer assembly further includes an anti-collision sensor 234 and a trigger 235. The anti-collision sensor 234 is fixed to the base 1 and configured to communicate with the moving mechanism. The trigger 235 is fixed to the guide 232 and is used to trigger the anti-collision sensor 234. The moving mechanism, connected to the base 1 of the film removal fixture, drives the film removal fixture to move so that the film hook 21 contacts the product 200. During this process, due to the action of the elastic member 233, the guide 232 slides up and down along the guide hole, thereby causing the trigger 235 to move up and down. When the trigger 235 moves to trigger the anti-collision sensor 234, the moving mechanism stops moving the film removal fixture. By setting the trigger 235 and the anti-collision sensor 234, a safety protection function is achieved to prevent the film hook 21 from impacting the product 200. In this embodiment, the trigger 235 is an L-shaped plate, one end of which is fixedly connected to the guide 232, and the other end of which is used to trigger the anti-collision sensor 234.

[0043] Optionally, in this embodiment, as Figure 3 and Figure 5 As shown, the cutting component 22 is a high-frequency vibrating knife, and the top of the film hooking component 21 is provided with a knife-avoiding groove 212. Specifically, the high-frequency vibrating knife is fixed to the base 1 by a vibrating knife fixing seat 221. The high-frequency vibrating knife cuts the film 100 through the blade 222, and a cutting space 24 is formed between the blade 222 and the film hooking component 21. The cutting component 22 is a high-frequency vibrating knife, which not only improves the cutting accuracy, speed, and quality of the film 100, but also significantly extends the service life of the knife and reduces maintenance costs, avoiding frequent knife replacements. By setting the knife-avoiding groove 212, when the high-frequency vibrating knife is vibrating, the blade 222 of the high-frequency vibrating knife vibrates up and down at a high frequency, and the knife-avoiding groove 212 can avoid the vibration space of the blade 222, preventing the blade 222 from colliding with the film hooking component 21. In addition, when the high-frequency vibrating knife is cutting the film 100, it can pass through the film 100 and be located within the knife-avoiding groove 212, which can achieve effective cutting of the film 100 and ensure the continuity and integrity of the cutting. Furthermore, the high-frequency vibrating knife in this embodiment is driven by a pneumatic method, and the airflow magnitude is adjusted by the airflow regulator 223.

[0044] Optionally, the first clamping member 32 includes a fixing part 321 and a clamping part 322. The fixing part 321 is fixed to the base 1, and the clamping part 322 is inclined relative to the base 1. With this configuration, when the moving mechanism moves the film-removing clamp, the surface of the clamping part 322 near the second clamping member 33 first contacts the film 100, which can smoothly hook the film 100, making it convenient for the second clamping member 33 to approach the first clamping member 32 and clamp the film 100. In addition, the clamping mechanism 3 can be set in different spatial positions as needed. In this embodiment, the clamping mechanism 3 is set back to back with the cutting mechanism 2, so that the cutting and clamping operations do not affect each other.

[0045] Optionally, in this embodiment, the second clamping member 33 is rotatably connected to the base 1, and the output end of the driving member 31 is connected to the second clamping member 33 to drive the second clamping member 33 to swing. When the second clamping member 33 rotates close to the first clamping member 32, the film 100 is clamped; when the second clamping member 33 rotates away from the first clamping member 32, the film 100 is released. This arrangement saves space and enables reliable clamping of the film 100. Further, the driving member 31 is a cylinder, which is rotatably connected to the base 1, and the cylinder's push rod is rotatably connected to the second clamping member 33. This arrangement ensures smooth and flexible swinging of the second clamping member 33 and has a lower cost. In addition, an electromagnetic valve island module 34 is installed on the base 1, which is used to control the flow of air in the cylinder. Of course, the driving member 31 can also be an electric push rod or a hydraulic cylinder, etc.

[0046] In other embodiments, the output end of the drive member 31 is connected to the second clamping member 33 and is used to drive the second clamping member 33 to translate, so that the second clamping member 33 moves closer to or away from the first clamping member 32.

[0047] Optionally, the clamping mechanism 3 further includes a detection sensor 35 for detecting the extension position of the cylinder push rod, and the detection sensor 35 is configured to communicate with the moving mechanism. The detection sensor 35 detects whether the second clamping member 33 and the first clamping member 32 are clamping the film 100 by detecting the extension position of the cylinder push rod. When the detection sensor 35 detects that the push rod has reached the specified extension position, that is, when the second clamping member 33 can clamp the film 100 with the first clamping member 32, the detection sensor 35 transmits information to the moving mechanism, and the moving mechanism begins to move the film removal clamp to pull the film 100, so that the film 100 is detached from the product 200, thereby realizing the collection of the film 100.

[0048] Optionally, both the first clamping member 32 and the second clamping member 33 are provided with soft rubber pads 37 to increase friction, increase the effective area of ​​the clamping membrane, and improve the stability of the clamping membrane.

[0049] Optionally, the clamping mechanism 3 also includes a membrane in-situ sensor 36, which is fixed to the first clamping member 32 and is used to detect whether the membrane 100 between the first clamping member 32 and the second clamping member 33 has fallen off when the membrane removal clamp is in different positions and postures.

[0050] Optionally, such as Figure 5 As shown, the film removal clamp also includes a distance sensor 4, which is fixed to the base 1 and used to detect the distance between the base 1 and the product 200. The distance sensor 4 is configured to communicate with the moving mechanism. When the moving mechanism carrying the film removal clamp approaches the product 200, the distance detection sensor 35 detects the distance between the base 1 and the product 200, guiding the moving mechanism to approach the product 200 at different speeds to avoid excessive speed and collision between the film removal clamp and the product 200.

[0051] Optionally, the film removal fixture also includes a protective cover 5, which covers the cutting mechanism 2 and the clamping mechanism 3 and is fixed to the base 1. The protective cover 5 serves a protective function, preventing dust from entering the cutting mechanism 2 and the clamping mechanism 3 and affecting their normal operation. In addition, the film removal fixture also includes a cable tray 6, a transfer junction box 7, and a mounting flange 8. The cable tray 6 and the transfer junction box 7 are used to fix and organize the wiring, and the mounting flange 8 is used to connect to the output end of the moving mechanism.

[0052] This utility model also provides a film removal device, including a moving mechanism and a film removal clamp, the output end of the moving mechanism being connected to the base 1. This film removal device can prevent tobacco auxiliaries from being cut. The film removal clamp in the device has a simple and compact structure, low cost, and a high degree of integration. When removing the film 100, the moving mechanism drives the film removal clamp to move, bringing the hook 21 into contact with the product 200. Then, the film removal clamp continues to move, causing the hook 21 to extend between the film 100 and the product 200, separating them. Afterward, the film removal clamp continues to move, causing the cutting member 22 to cut the film 100 covering the hook 21. After cutting, the moving mechanism moves the film removal clamp to a position where it is easy to grip and peel off the film 100. Once in the position, the driving member 31 drives the second clamping member 33 to move, bringing the second clamping member 33 closer to the first clamping member 32 to clamp the film 100. After clamping, the moving mechanism drives the film removal fixture to move, peeling the film 100 from the product 200. Optionally, the moving mechanism is a robotic arm.

[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
