[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0025] It should be noted that, in the description of the present invention, the front refers to the direction in which the tape is unfolded, the rear refers to the position of the tape roll, and the left and right directions refer to the direction in which the tape is unfolded, which is consistent with the left and right directions shown from the operator's perspective. It is based on the orientation or position relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0026] In the claims, specification and drawings of this application, unless otherwise explicitly defined, the use of terms such as "first", "second" or "third" etc. are intended to distinguish different objects rather than to describe a specific order.

[0027] Please also read Figures 1 to 4 The tape stripping device provided by the utility model is now described. The tape stripping device comprises a bottom plate 1 and a tape roller 12, a guide roller 9, a pressing mechanism 7, a clamping mechanism 4 and a dragging mechanism arranged on the bottom plate 1; the guide roller 9, the pressing mechanism 7, the clamping mechanism 4 and the dragging mechanism are successively away from the tape roller 12 in the direction of tape unwinding; the clamping mechanism 4 is connected to the dragging mechanism; the tape roller 12 is used to place the tape roll 11; the pressing mechanism 7 presses the tape guided by the guide roller 9; the clamping mechanism 4 clamps the head end of the tape; the dragging mechanism drives the clamping mechanism 4 to move forward to strip the tape from the tape roll 11.

[0028] The adhesive tape stripping device provided by the utility model has the following beneficial effects compared with the prior art: when labeling is required, the adhesive tape roll 11 is placed on the adhesive tape roller 12, the head end of the adhesive tape is first pulled out manually, the head end of the adhesive tape is pressed by the pressing mechanism 7, and the head end of the adhesive tape is exposed for easy clamping by the clamping mechanism 4, the clamping mechanism 4 is driven by the dragging mechanism to approach the pressing mechanism 7 and clamp the head end of the adhesive tape, and then the dragging mechanism drives the clamping mechanism 4 to move forward, at this time the pressing mechanism 7 is loosened until the adhesive tape can move forward with the clamping mechanism 4, and the adhesive tape can be stripped from the adhesive tape roll 11, when the adhesive tape is stripped to the required length, the pressing mechanism 7 presses the adhesive tape, the two ends of the adhesive tape segment 19 are respectively fixed, at this time the adhesive tape is cut from the front of the pressing mechanism 7 by the configured cutting mechanism, and a certain length is reserved for the next clamping of the clamping mechanism 4 (see Figure 4 As shown, arrow a indicates the cutting point); in this way, the tape on the tape roll 11 can be automatically cut into sections for labeling as needed. The whole process only requires manual assistance, and the tape can be automatically cut as needed, making the labeling work easy and labor-saving. When it is configured on the automated production line of the product, it reaches the labeling station and can automatically label the product, meeting the needs of automated production.

[0029] Among them, a length measuring sensor 6 is arranged between the pressing mechanism 7 and the clamping mechanism 4 on the bottom plate 1. Specifically, a detection bracket 5 is arranged on the bottom plate 1, and the length measuring sensor 6 is arranged on the detection bracket 5. The length measuring sensor 6 measures the length of the tape clamped by the clamping mechanism 4 as it is unfolded by the dragging mechanism. When the unfolded length of the tape reaches the preset labeling length value, the signal of the length measuring sensor 6 is fed back to the controller, and the controller instructs the cutting mechanism to cut the tape at the preset length position; of course, a grabbing manipulator is also configured to take away the cut tape for labeling.

[0030] Furthermore, in view of the situation where multiple tape rollers 12 are simultaneously peeling off the tape, each corresponding tape roller 12 is provided with a length measuring sensor 6. The length measuring sensor 6 is a device for measuring the length or displacement of an object. It is based on physical principles and sensor technology and can accurately and reliably measure the size change of the target object. In this embodiment, a non-contact length measuring sensor 6 can be selected. The non-contact length measuring sensor 6 refers to a sensor that does not need to directly contact the surface of the target object during the measurement process. This type of sensor has the characteristics of non-destructiveness and high precision. Common non-contact length measuring sensors 6 include laser rangefinders, photoelectric encoders, ultrasonic sensors, etc. They use physical signals such as light and sound waves to interact with the target object and calculate the length or displacement by measuring the change in the signal.

[0031] Since the device provided in this embodiment is for peeling off the adhesive tape, the detailed structure of the cutting mechanism is not shown in the figure. However, it is explained here that the cutting mechanism is located close to the clamping mechanism 7 and between the length measuring sensor 6 and the clamping mechanism 7.

[0032] For example, the cutting mechanism includes a pneumatic scissors and a linear slide perpendicular to the tape unfolding direction. The pneumatic scissors are driven by the linear slide to move in the perpendicular direction of the tape unfolding direction, and the unfolded multiple tapes can be cut. For example, the pneumatic scissors move from the left side to the right side of the bottom plate 1 to cut the tape. After cutting the tape, the linear slide drives the pneumatic scissors to return to the left side of the bottom plate 1 to prepare for the next cutting work.

[0033] In some embodiments, see Figures 1 to 3 , Figure 5 As shown, a first bracket 18 is provided on the bottom plate 1, a first support shaft 10 is provided on the first bracket 18, and a tape roller 12 is rotatably mounted on the first support shaft 10; a retaining ring 121 is provided at the inner end of the tape roller 12, and a cover plate 14 is provided at the outer end of the tape roller 12, and the retaining ring 121 and the cover plate 14 are limited to place the tape roll 11 on the tape roller 12. When installing the tape roll 11, the cover plate 14 is opened, the tape roll 11 is inserted into the tape roller 12, and then the cover plate 14 is installed. At this time, the axial ends of the tape roll 11 are respectively limited by the retaining ring 121 and the cover plate 14, and will not fall off the tape roller 12, which facilitates the installation of the tape roll 11.

[0034] The first bracket 18 is a plate-like structure with a horizontal folded plate at the bottom, which is convenient for fastening to the bottom plate 1 by bolts. The shaft end of the first support shaft 10 is fixed to the first bracket 18 by bolts; the tape roller 12 is rotatably mounted on the first support shaft 10 through the bearing 13; wherein the bearing 13 is limited at both ends on the first support shaft 10 by the shaft retaining spring.

[0035] Preferably, the first bracket 18 is provided with reinforcing ribs in the vertical direction to improve the supporting rigidity of the first bracket 18 .

[0036] In some embodiments, see Figures 1 to 3 As shown, a limit pin (not shown in the figure) is provided on the outer end axis of the first support shaft 10, and a limit hole is provided on the cover plate 14 to be rotatably connected with the limit pin; the two ends of the cover plate 14 are connected to the outer end of the tape roller 12 by bolts. The cover plate 14 is rotatably connected to the axis limit pin of the first support shaft 10, so that the cover plate 14 can pass through the axis of the tape roller 12 and be positioned, and ensure that the cover plate 14 rotates with the tape roller 12; in order to facilitate the removal of the cover plate 14 and the installation of the tape roller 12, the cover plate 14 is fixed to the outer end of the tape roller 12 by bolts. Among them, the limit pin is also preferably a bolt, which is screwed on the first support shaft 10 and has a nut to limit the cover plate 14. At this time, when the tape roll 11 needs to be assembled, the bolt needs to be removed; or the limit pin can be cylindrical. Since both ends of the cover plate 14 are fixed on the tape roller 12, the limit pin does not need to limit the axial position of the cover plate 14.

[0037] It should be noted that the outer end here refers to the end of the tape roller 12 axially facing away from the first bracket 18 , and the inner end refers to the end of the tape roller 12 axially close to the first bracket 18 .

[0038] Optionally, the cover plate 14 is a long strip, and after being fixed on the tape roller 12 , both ends of the cover plate 14 extend beyond the circumferential surface of the tape roller 12 at corresponding positions.

[0039] In some embodiments, see Figures 1 to 3 As shown, a second bracket 15 is provided on the bottom plate 1, a second support shaft 8 is provided on the second bracket 15, and a guide roller 9 is rotatably connected to the second support shaft 8. The second support shaft 8 is parallel to the first support shaft 10, and its height direction can be higher than the first support shaft 10 or lower than the first support shaft 10, and the guide roller 9 can guide the unfolded tape.

[0040] Optionally, the guide roller 9 is rotatably connected to the second support shaft 8 via a bearing 13 .

[0041] In some embodiments, see Figures 1 to 3 , Figure 6 As shown, baffle plates 91 for limiting the position of the tape are respectively arranged at the axial ends of the guide roller 9, which can prevent the tape from deviating and keep the tape from unwinding straight forward.

[0042] In some embodiments, see Figures 1 to 3 As shown, the second bracket 15 includes two vertical plates arranged on the left and right, and a long hole is vertically arranged on the upper edge of the vertical plate, and the two ends of the second support shaft 8 are respectively penetrated through the long hole; the vertical plate is provided with a lifting mechanism for adjusting the height of the second support shaft 8. The lifting mechanism on the vertical plate can drive the height adjustment of the second support shaft 8, thereby adjusting the height of the guide roller 9, so as to guide and tighten the tape in coordination with the tape roller 12 of different heights.

[0043] For example, in this embodiment Figures 1 to 4 Given two groups of tape rollers 12 of different heights, the second support shaft 8 is adjusted downward by the lifting mechanism to match the tape roller 12 at a lower position. Of course, when the position of the guide roller 9 is higher than the lower tape roller 12, it also has a guiding function.

[0044] The bottom of the vertical plate is also fastened to the bottom plate 1 by bolts. At the same time, in order to adjust the distance between the two vertical plates, the mounting hole at the bottom of the vertical plate can be made into a long hole, and the length direction of the long hole is consistent with the axial direction of the second support shaft 8. Similarly, the position of the first bracket 18 along the left and right direction can also be adjusted.

[0045] When the device includes a plurality of adhesive tape rollers 12, the plurality of adhesive tape rollers 12 are all located between the two vertical plates.

[0046] It should be noted that the left and right directions referred to herein are directions that can be determined when looking backward from the direction in which the tape is unrolled, that is, the two ends of the second support shaft 8 are left and right directions respectively. The direction in which the tape is unrolled is the front direction, for example, the dragging mechanism is in front of the clamping mechanism 7.

[0047] Regarding the embodiments of the lifting mechanism, it can be a cylinder, a hydraulic cylinder, an electric push rod or a worm gear lifting mechanism, all of which can drive the second support shaft 8 to move up and down.

[0048] In some embodiments, see Figures 1 to 3 As shown, the pressing mechanism 7 includes a third bracket arranged on the bottom plate 1 and a pressing cylinder installed on the third bracket. The third bracket includes a support plate 16 and a vertical plate 17 arranged on the support plate 16. The cylinder body of the pressing cylinder is installed on the vertical plate 17. The pressing block connected to the pressing cylinder can press the tape flatly on the support plate 16. The cylinder rod of the pressing cylinder rises and falls in the vertical direction to press or leave the tape.

[0049] The clamping mechanism 7 may also be a hydraulic cylinder or an electric push rod, wherein the actuating rod of each clamping mechanism 7 is connected with a pressure block to clamp the adhesive tape.

[0050] In some embodiments, see Figures 1 to 3 As shown, the clamping mechanism 4 includes a finger cylinder, which clamps the tape by opening the fingers.

[0051] In some embodiments, see Figures 1 to 3 As shown, the dragging mechanism includes a dragging cylinder 2, a cylinder rod of the dragging cylinder 2 is arranged on a dragging plate 3, and a clamping mechanism 4 is installed on the dragging plate 3. When the cylinder rod of the dragging cylinder 2 is contracted, the clamping mechanism 4 can be pulled forward and the tape can be unfolded.

[0052] Optionally, the dragging mechanism may also be a hydraulic cylinder or an electric push rod.

[0053] In some embodiments, see Figures 1 to 4 As shown, it includes a plurality of tape rollers 12 arranged at intervals, each of which is equipped with the guide roller 9, the pressing mechanism 7 and the clamping mechanism 4, and each clamping mechanism 4 is connected to the dragging mechanism. A plurality of tape rollers 12 are provided, each of which can simultaneously peel and cut the tape, and the dragging mechanism can simultaneously drive each tape to peel and unfold, which greatly improves the efficiency of tape peeling, thereby improving the efficiency of label attachment.

[0054] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
