Abstract
Description
Technical Field
[0001] This utility model belongs to the field of tape winding technology, specifically relating to a tape length fastening device. Background Technology
[0002] In the recycling process of battery cell packaging boxes, the labels on the packaging boxes need to be removed, which requires the use of an automatic label-removing device.
[0003] Existing automatic label-removing devices have some problems during use, such as:
[0004] 1. Controlling the length of the tape feed by the number of rotations or the duration of rotation. As the tape roll is used and consumed, its diameter will decrease significantly, making it impossible to achieve precise length setting, resulting in tape waste or the inability to tear off the label.
[0005] 2. The tape cannot be stretched taut, resulting in poor label removal. Utility Model Content
[0006] The purpose of this invention is to provide a tape length-fixing device to solve the problems mentioned in the background art. The tape length-fixing device provided by this invention features precise tape feeding at a fixed length.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a tape fixed-length fastening device, comprising a connecting plate, a tape winding assembly mounted on one end of the connecting plate, and a tape unwinding assembly mounted on the other end of the connecting plate. The tape winding assembly includes a winding seat, a winding sleeve rotatably mounted on the upper end of the winding seat, and a winding motor mounted on the winding seat for driving the winding sleeve to rotate. The tape unwinding assembly includes an unwinding seat, an unwinding sleeve rotatably mounted on the upper end of the unwinding seat, a follower roller mounted below the unwinding seat, a stop block mounted on one end of the follower roller, and a counting sensor corresponding to the end of the stop block mounted on the mounting bracket of the follower roller. The winding motor and the counting sensor are respectively connected to a PLC controller signal.
[0008] To further guide the tape, a take-up guide roller is installed below the take-up seat, and an unwind guide roller is installed below the unwind seat.
[0009] To further limit the movement of the take-up sleeve, an indexing plate is installed on the take-up sleeve, and the circumference of the indexing plate is provided with several limit grooves arranged in a ring. The take-up base is equipped with limit blocks corresponding to the limit grooves.
[0010] In order to enable the winding sleeve to rotate clockwise under the drive of the winding motor, and to prevent it from rotating counterclockwise under the action of the tape tension after the winding motor stops, the limiting block further includes a mounting base, on which a limiting block rotates, and an inclined block is provided at the end of the limiting block away from the rotating part, and the back of the inclined block is connected to the mounting base by a spring.
[0011] To further limit the movement of the unwinding sleeve, a limiting plate is installed on the unwinding sleeve, and the limiting plate has several limiting holes arranged in a ring on its circumference. A limiting component corresponding to the limiting plate is installed on the side of the unwinding base. The limiting component includes a mounting bracket, on which a cylinder is mounted, and a limiting pin is connected to the output end of the cylinder.
[0012] In order to heat the label during the label-tearing action, making it easier to tear off the label, the connecting plate is further designed as an electric heating plate.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model utilizes a conveyor belt to drive a follower roller to rotate. A stop block is installed at the end of the follower roller. A counting sensor counts the number of rotations of the stop block. The length of the conveyor belt is set according to the number of rotations of the follower roller, so as to achieve precise fixed-length conveying of the conveyor belt.
[0015] 2. This utility model uses a limiting component and a limiting plate to limit the unwinding sleeve, and a limiting block and an indexing plate to limit the winding sleeve. The combination of these two components tightens the tape. By controlling the stopping time of the winding motor, the tension of the tape can be controlled, thus avoiding both excessive tightness that causes tape deformation and excessive looseness that prevents the label from being torn off, ensuring the label tearing effect.
[0016] 3. The connecting plate of this utility model is an electric heating plate, which heats the label during the label-tearing action, making it easier to tear off the label. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example 1
[0024] Please see Figures 1-5 This utility model provides the following technical solution: a tape fixed-length fastening device, including a connecting plate 1, a tape winding assembly 2 installed on one end of the connecting plate 1, and a tape unwinding assembly 3 installed on the other end of the connecting plate 1. The tape winding assembly 2 includes a winding seat 21, a winding sleeve 24 rotatably mounted on the upper end of the winding seat 21, and a winding motor 22 for driving the winding sleeve 24 to rotate, the winding motor 22 being a servo motor. The output end of the winding motor 22 is connected to the winding sleeve 24 via a synchronous pulley group. The tape unwinding assembly 3 includes an unwinding seat 31, an unwinding sleeve 32 rotatably mounted on the upper end of the unwinding seat 31, a follower roller 33 installed below the unwinding seat 31, a stop block 35 installed on one end of the follower roller 33, and a counting sensor 36 corresponding to the end of the stop block 35 installed on the mounting bracket of the follower roller 33. The winding motor 22 and the counting sensor 36 are respectively connected to the PLC controller signal.
[0025] By adopting the above technical solution, this utility model uses a conveyor belt to drive the follower roller 33 to rotate. A stop block 35 is installed at the end of the follower roller 33. The number of rotations of the stop block 35 is counted by a counting sensor 36. The length of the conveyor belt is set according to the number of rotations of the follower roller 33, so as to achieve precise fixed-length conveying of the conveyor belt.
[0026] Specifically, a take-up guide roller 23 is installed below the take-up holder 21, and an unwinding guide roller 34 is installed below the unwinding holder 31.
[0027] The above technical solution is used to guide the tape.
[0028] Example 2
[0029] The difference between this embodiment and embodiment 1 is that: specifically, an indexing plate 5 is installed on the winding sleeve 24, and a plurality of limit grooves 51 arranged in a ring array are provided on the circumference of the indexing plate 5. A limit block 4 corresponding to the limit groove 51 is installed on the winding seat 21.
[0030] By adopting the above technical solution, the limiting block 4 and the indexing plate 5 are used to limit the winding sleeve 24.
[0031] Specifically, the limiting block 4 includes a mounting base 41, on which a limiting block 42 rotates. The end of the limiting block 42 away from the rotating part is provided with an inclined block 43, and the back of the inclined block 43 is connected to the mounting base 41 by a spring.
[0032] By adopting the above technical solution, the winding sleeve 24 can rotate clockwise under the drive of the winding motor 22. When the winding motor 22 stops, it cannot rotate counterclockwise under the action of the tape tension.
[0033] Specifically, a limiting plate 6 is installed on the unwinding sleeve 32. The circumference of the limiting plate 6 is provided with a plurality of limiting holes 61 arranged in a ring. A limiting component 7 corresponding to the limiting plate 6 is installed on the side of the unwinding base 31. The limiting component 7 includes a mounting bracket 71. A cylinder 72 is installed on the mounting bracket 71. A limiting pin 73 is connected to the output end of the cylinder 72.
[0034] By adopting the above technical solution, the cylinder 72 drives the limit pin 73 to be inserted into the limit hole 61 to limit the unwinding sleeve 32.
[0035] This utility model uses the limiting component 7 and the limiting plate 6 to limit the unwinding sleeve 32, and the limiting block 4 and the indexing plate 5 to limit the winding sleeve 24. With the cooperation of the two, the tape is tightened. By controlling the stopping time of the winding motor 22, the tension of the tape can be controlled, so as to avoid the tape being too tight and deforming, and also to avoid it being too loose and unable to tear the label, thus ensuring the label tearing effect.
[0036] Example 3
[0037] The difference between this embodiment and embodiment 1 is that, specifically, the connecting plate 1 is an electric heating plate.
[0038] By adopting the above technical solution, the label is heated during the label-tearing action, making it easier to tear off the label.
[0039] The working steps of this utility model are as follows:
[0040] (1) Put the whole roll of new tape onto the unwinding sleeve 32, put the empty tape roll onto the take-up sleeve 24, and then manually pull the tape from the outside through the follower roller 33, the unwinding guide roller 34 and the take-up guide roller 23 in sequence, and wind the tape onto the empty tape roll to complete the installation and pulling of the tape.
[0041] (2) Before the first label-tearing action after the new tape is installed, the tape is manually wound up and the indexing plate 5 is adjusted so that the limit block 4 is locked in the appropriate position. After the adjustment is completed, the equipment switches to automatic mode and starts the label-tearing action.
[0042] (3) After a label-tearing action is completed, the cylinder 72 drives the limit pin 73 to retract and separate from the limit hole 61. The winding motor 22 works and drives the winding sleeve 24 to rotate to wind the tape. When the counting sensor 36 detects that the stop block 35 rotates a set number of times, the cylinder 72 drives the limit pin 73 to extend and insert into the limit hole 61.
[0043] (4) After the winding motor 22 continues to rotate a set number of times, it stops. The inclined block 43 of the limit block 4 is embedded in the limit groove 51 to limit the winding sleeve 24 and tighten the tape.
[0044] (5) Perform the label-tearing action again.
[0045] In summary, this invention utilizes the adhesive tape to drive the follower roller 33 to rotate. A stop block 35 is installed at the end of the follower roller 33. The number of rotations of the stop block 35 is counted by the counting sensor 36. The length of the adhesive tape is set according to the number of rotations of the follower roller 33, achieving precise fixed-length conveying of the adhesive tape. This invention uses the limiting component 7 and the limiting plate 6 to limit the unwinding sleeve 32, and the limiting block 4 and the indexing plate 5 to limit the winding sleeve 24. The combination of these two components achieves the tension of the adhesive tape. By controlling the stopping time of the winding motor 22, the tension of the adhesive tape can be controlled, thus avoiding both excessive tightness that causes deformation and excessive looseness that makes it impossible to tear the label, ensuring the label tearing effect. The connecting plate 1 of this invention is an electric heating plate, which heats the label during the label tearing action, making it easier to tear off the label.
[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
