Description

Technical Field

[0001] The utility model relates to a tape feeding mechanism of a release tape taping device Background Art

[0002] On packaging cartons or bags (such as envelopes), a release tape (such as a strip of release paper or film) is applied to the packaging material. The tape can be removed for sealing or other operations when the packaging material is used. The release tape can be pressed against the packaging material by a floating roller (such as a roller mounted on a swing arm) through a floating fit. This method can easily cause the release tape to become entangled with the roller, causing the pre-applied glue strips on the packaging material to be carried onto the roller, coating the entire structure with glue and requiring machine downtime to clean the glue. This is troublesome, time-consuming, and labor-intensive, and even after cleaning, glue residue may remain. Once this occurs, subsequent production operations are prone to release tape entanglement, resulting in unstable operation and frequent downtime for release tape and glue cleaning, leading to low production efficiency and increased production costs. In addition, this floating roller is driven to continuously float (such as swing) at high speed during the production process to cooperate with pressing the release tape onto the preset glue strip on the packaging material. It makes a lot of noise, affects the entire production environment, and is difficult to further increase the speed. Utility Model Content

[0003] In view of the technical problems existing in the background technology, the utility model aims to provide a tape feeding mechanism of a release tape taping device which has relatively stable operation, is not easy to entangle the release tape, has relatively high speed and low noise.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: the tape feeding mechanism of the release tape taping device includes a frame, on which a tape feeding device, a tape cutting device and a guiding component are provided, and the characteristics are: the tape feeding device is connected and arranged above the tape cutting device, the guiding component is connected and arranged below the tape cutting device, the tape feeding device includes a matching tape feeding roller and a tape feeding pressure roller, the tape feeding pressure roller is arranged on the front side or the rear side of the tape feeding roller, the tape cutting device includes a cutting knife for cutting the release tape body, the guiding component has a tape body guiding surface, the upper end of the tape body guiding surface is the tape body input end, and the lower end of the tape body guiding surface is the tape body output end.

[0005] The following various optimizations or supplementary explanations can be made on the above technical solutions respectively.

[0006] For example, the guide component is arranged above the translation conveying path of the conveyor belt for conveying packaging materials; the translation conveying path of the conveyor belt is arranged to convey forward; the belt guide surface is arranged to face backward, and the rear side of the belt guide surface is the belt downward movement path.

[0007] Wherein, a tape fitting distance is reserved between the belt output end of the belt guide surface and the translation conveying path of the conveyor belt.

[0008] In addition, at the tape fitting spacing, the head of the tape cutting head pre-feeds the tape to the bottom and drags it on the conveyor belt before taping; the tape fitting spacing matches the thickness of the packaging material, and the belt matching gap is between the belt output end at the lower end of the belt guide surface and the packaging material on the conveyor belt.

[0009] For example, the conveyor belt adopts a suction belt, and is equipped with a material pressing auxiliary conveyor belt or a material pressing auxiliary conveyor wheel above the conveyor belt.

[0010] For another example, the belt guide surface is arranged to guide from top to bottom, and the belt output end at the lower end of the belt guide surface is bent forward.

[0011] For example, the belt output end at the lower end of the belt guide surface is curved forward.

[0012] In addition, the mounting position of the frame is adjusted up and down; and / or the distance between the belt output end of the belt guide surface and the translational conveying path of the conveyor belt is adjusted.

[0013] For example, the feed roller is connected to the feed drive motor; the cutting blade is connected to the tape cutting drive motor; and the conveyor belt is a continuous non-stop tape feeding belt. For example, the tape cutting device includes a blade support roller and a blade pad roller. The cutting blade is mounted on the blade support roller, and the blade pad roller is positioned in front of or behind the blade support roller. The cutting blade is connected to the tape cutting drive motor via the blade support roller.

[0014] For example, the feeding drive motor and the tape cutting drive motor respectively use servo motors; the feeding drive motor and the cutter drive motor match the conveyor belt; the tape feeding roller is a fixed-length conveyor roller.

[0015] The beneficial effect of the present invention is that the release tape taping device has a tape feeding mechanism, wherein the release tape body is pulled and fed by the tape feeding device, the tape cutting device is used to cut the release tape body to make it detached, and the guide component is used to guide the release tape body to be output, and is used to cooperate with feeding the release tape body to the taping device, and no floating roller is needed to stick the release tape on the object, thereby avoiding the problems of the release tape being entangled on the roller and needing to be released and the need to clean the glue, thereby improving the operation stability, and without the need for floating rollers, the operation noise is relatively small and the speed is relatively fast.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the implementation of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0031] Referring to the accompanying drawings, in an embodiment of this embodiment, the tape feeding mechanism of the release tape taping device includes a frame 1, on which a tape feeding device 2, a tape cutting device 3 and a guide component 4 are provided. The frame 1 is used for installing the tape feeding device 2, the tape cutting device 3 and the guide component 4.

[0032] The tape feeder 2 is positioned above the tape cutter 3, and the guide component 4 is positioned below the tape cutter 3. The release tape (such as a continuously rolled strip of release paper or film) is fed downward by the tape feeder 2 (the tape length can be adjusted as needed), causing the tape to be transported downward. After passing through the tape cutter 3, the guide component 4 cooperates with the limit guide to guide the tape downward for application. After the release tape is successfully applied to the packaging material 6, the tape cutter 3 cuts the tape to the required length (which can be adjusted as needed).

[0033] Among them, the tape feeding device 2 includes a matching tape feeding roller 20 and a tape feeding pressure roller 21. The tape feeding pressure roller 21 is arranged on the front side or the rear side of the tape feeding roller 20. The tape feeding roller 20 and the tape feeding pressure roller 21 cooperate to clamp and rotate to pull the release tape body downward.

[0034] The tape cutting device 3 includes a cutting knife 30 , and the cutting knife 30 of the tape cutting device 3 is used to cut the release tape body.

[0035] Among them, the guiding component 4 has a belt guiding surface 40, the upper end of the belt guiding surface 40 is the belt input end, and the lower end of the belt guiding surface 40 is the belt output end 401. The release belt is smoothly output from top to bottom, specifically: it is input from the belt input end, passes through the guiding component 4, and is output from the belt output end 401.

[0036] The release tape taping device has a tape feeding mechanism, wherein the release tape body is pulled and fed by the tape feeding device 2, and then the tape cutting device 3 cuts the release tape body to make it detached, and the guide component 4 guides the release tape body to be output, which is used to cooperate with feeding the release tape body to the object for taping. There is no need for a floating roller to cooperate with the release tape to stick on the object, which avoids the problem of the release tape being entangled on the roller and needing to be released and the need to clean the glue, thereby improving the operation stability. Without the need for a floating roller, the operation noise is relatively small and the speed is relatively fast.

[0037] The following optimization or further explanation may be performed based on the above embodiments.

[0038] For example, the guide component 4 is disposed above the translational conveying path of the conveyor belt 5. The conveyor belt 5 is used to convey packaging material 6, such as packaging cartons or packaging bags (such as envelope packaging bags). The packaging material 6 is translated by the conveyor belt 5. The guide component 4 is located above the translational conveying path of the packaging material 6 to cooperate with the tape application. A gluing station and a taping station are configured along the translational conveying path of the conveyor belt 5. The frame 1 is configured at the taping station. The gluing station can be equipped with a gluing device (such as a glue gun) for pre-applying glue (spraying glue) to the packaging material 6 to form a glue strip 60. The release tape taping device then cooperates with the tape feeding device 2, the tape cutting device 3, and the guide component 4 on the frame 1 of the tape feeding mechanism to deliver the release tape body to the taping device for taping.

[0039] For example, the conveyor belt 5 is arranged with its translational conveying path facing forward, i.e., the conveyor belt 5 translates forwardly to convey the packaging material 6. The belt guide surface 40 is arranged rearwardly, and the rear side of the belt guide surface 40 forms the belt downward movement path. The release tape moves downwardly from the rear side (the belt downward movement path) of the belt guide surface 40. With the belt guide surface 40 of the guide component 4 positioned to guide the front side of the release tape, when the conveyor belt 5 translates forwardly, it can pull the end of the release tape (i.e., the head 61 of the tape cutting head) in the conveying direction, causing the head 61 (the end of the release tape) to bend forward and rest against the conveyor belt 5. At this point, when the conveyor belt 5 carrying the packaging material 6 (e.g., a packaging carton or packaging bag) passes beneath the guide component 4, the release tape can be smoothly attached to the adhesive strip 60 of the packaging material 6.

[0040] Among them, a tape fitting spacing 50 is left between the tape output end 401 of the tape guiding surface 40 of the guiding component 4 and the translational conveying path of the conveyor belt 5, which not only ensures that the packaging material 6 can pass through and advance smoothly, but also enables the head 61 of the tape cutting head to be dragged and pulled by the conveyor belt 5. The head 61 of the tape cutting head bends forward and rests on the conveyor belt 5, ensuring that the release tape is smoothly and stably attached to the pre-glued adhesive strip 60.

[0041] At the taping fitting distance 50, the head 61 of the tape cutting head is pre-fed before taping, touching the bottom of the tape and dragging it on the conveyor belt 5. That is, during operation, before each taping operation, the release tape is pre-fed by the tape feeding device 2, so that the head 61 of the tape cutting head (the end of the release tape) contacts the bottom of the conveyor belt 5. The head 61 of the tape cutting head drags on the conveyor belt 5, allowing it to smoothly bend forward and rest on the conveyor belt 5. The taping fitting distance 50 is designed to match the thickness of the packaging material 6. Typically, the taping fitting distance 50 is slightly larger than the thickness of the packaging material 6 and the release tape, but it can be adjusted to match them as needed to ensure stable operation. The gap between the tape output end 401 at the lower end of the tape guide surface 40 and the packaging material 6 on the conveyor belt 5 is the tape matching gap. That is, the taping fitting distance 50 matches the thickness of the packaging material 6 and the release tape.

[0042] For example, the conveyor belt 5 is a suction belt that can suck the packaging material 6 for conveying, ensuring that the packaging material 6 does not shift during the conveying and taping process, and the taping is stable and accurately positioned. In addition, a material pressing auxiliary conveyor belt or material pressing auxiliary conveyor wheel is also provided above the conveyor belt 5 to prevent the packaging material 6 from shifting by pressing and coordinating the conveying and taping.

[0043] The belt guide surface 40 is arranged to guide downward (e.g., vertically), and the belt output end 401 at the lower end of the belt guide surface 40 is curved forward. This prevents the head 61 of the belt cutting head from being creased when dragged by the conveyor belt 5. Furthermore, the release tape is also less likely to be broken or scratched when it is pulled along with the conveyor belt during the taping process. For example, the belt output end 401 at the lower end of the belt guide surface 40 is curved forward, which provides a relatively smoother and more fluid flow.

[0044] In addition, the vertical adjustment of the mounting position of the frame 1 allows the vertical adjustment of the entire structure; and / or the spacing adjustment between the belt output end 401 of the belt guide surface 40 and the translational conveying path of the conveyor belt 5 can be adjusted separately by adjusting the guide component 4 (such as the guide block). This allows the spacing between the belt output end 401 at the lower end of the belt guide surface 40 and the translational conveying path of the conveyor belt 5 below the bottom to be adjusted, thereby ensuring stable belt feeding and taping operations.

[0045] For example, the feed roller is in transmission connection with the feed drive motor 22, which drives the feed roller to rotate and convey the release tape downward. The cutter 30 is in transmission connection with the tape cutting drive motor 31, which drives the cutter 30 to cut the release tape. For example, the conveyor belt 5 is a continuous non-stop taping feed belt. That is, during the taping process, the conveyor belt 5 runs continuously and non-stop, conveying the packaging materials 6 one by one, which is more efficient. The tape feeding mechanism of the release tape taping equipment can cooperate with the efficient operation of the conveyor belt 5. For example, the tape cutting device 3 includes a knife seat roller 32 and a knife pad roller 33. The cutting knife 30 is set on the knife seat roller 32. The cutting device 3 is cut by rotating. The cutting knife 30 rotates with the knife seat roller 32 to cooperate with the cutting action. The knife pad roller 33 is arranged on the front side or the rear side of the knife seat roller 32. The knife pad roller 33 cooperates with the cutting knife 30 to smoothly cut the release tape body. The cutting knife 30 is connected to the tape cutting drive motor 31 through the knife seat roller 32. A mounting groove 321 can be formed on the knife seat roller 32 for the cutting knife 30 to be fastened and assembled.

[0046] In addition, the feed drive motor 22 and the cutter drive motor 31 can each be a servo motor, which provides more precise operation and facilitates the coordinated operation of the conveyor belt 5 and the packaging material 6 thereon. The feed drive motor 22 and the cutter drive motor are matched to the conveyor belt 5 and can be coordinated and operated using an encoder, a controller, etc. Furthermore, the tape feed roller 20 is a fixed-length conveyor roller.
