DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0022] Embodiment one

[0023] Please refer to the drawings Figures 1-2 A tape winding device with bubble removal function, comprising:

[0024] The work platform 1, two winding frames 2, winding rollers 3, two connecting frames 4 and extrusion rollers 5, the winding frame 2 is fixedly connected to the work platform 1, the winding roller 3 is bearing connected to two groups of winding frames 2 at both ends respectively, and one end of the winding roller 3 is connected with the motor 30 after penetrating through the winding frame 2, the motor 30 is fixedly connected to the fixed body, two connecting frames 4 are connected with two winding frames 2 respectively, and the connecting frame 4 is provided with a sliding groove 40, the sliding groove 40 is provided with a sliding block 41 matched therewith in the sliding groove 40, and the extrusion roller 5 is bearing connected with two sliding blocks 41 at both ends respectively;

[0025] The mode that the connecting frame 4 is carried on the winding frame 2 makes the extrusion roller 5 located above the winding roller 3, and then the extrusion of the tape in the winding process on the winding roller 3 is completed through the gravity of the extrusion roller 5 itself, so that the purpose that the bubbles possibly existing on the tape on the winding roller 3 are removed through extrusion is achieved, it needs to be noted that the tape is guided through other guide rollers on the tape production line, so that the position where the winding roller 3 and the extrusion roller 5 contact is the position where the tape is wound on the winding roller 3, then the effect that the bubbles existing in the tape adhesive part are removed through extrusion is best, at the same time, considering that the outer diameter of the tape roll increases with time in the process of winding the tape, if the position of the extrusion roller 5 cannot move with the outer diameter of the tape roll, then the extrusion roller 5 cannot complete the purpose of bubble removal, and will hinder the winding of the tape, therefore, the sliding groove 40 and the sliding block 41 slidingly connected therewith are arranged on the connecting frame 4, through the variable position of the sliding block 41, the purpose that the position of the extrusion roller 5 is variable is achieved.

[0026] In view of the fact that different types of adhesive tapes may have different radii of the adhesive tape roll in the actual application, in order to further strengthen the auxiliary effect of the extrusion roller 5 on the winding roller 3, the extrusion roller 5 is provided with a limiting function. Specifically, at least one of the connecting frames 4 is provided with a limiting assembly 6. The limiting assembly 6 comprises a threaded sleeve 60, a connecting rod 61 and an adjusting handle 62. One end of the threaded sleeve 60 is fixedly connected with the adjusting handle 62, and the other end penetrates through the top wall of the sliding groove 40 and is threadedly connected with the sliding groove 40. The connecting rod 61 is located in the sliding groove 40, one end of the connecting rod 61 is fixedly connected with the sliding block 41, and the other end is sleeved in the threaded sleeve 60. Through the arrangement of the threaded sleeve 60 and the adjusting handle 62, the vertical position of the threaded sleeve 60 can be changed. When the threaded sleeve 60 is at different heights, it means that the upper limit of the connecting rod 61 sleeved in the threaded sleeve 60 can also be changed. Then, by changing the upper limit of the connecting rod 61, the position limit of the sliding block 41 fixedly connected with the connecting rod 61 is changed, so as to limit the maximum radius of the adhesive tape roll on the winding roller 3 by the extrusion roller 5. It should be noted that in the actual application, a sound or light alarm switch can be arranged in the threaded sleeve 60. When the radius of the adhesive tape roll reaches a certain radius, the upper end of the connecting rod 61 can press the alarm switch, reminding the staff that the single winding is about to be completed through sound or light, and the staff needs to prepare for the roll change and cutting in advance.

[0027] Specifically, the side wall of the connecting frame 4 provided with the limiting assembly 6 is provided with a scale. In order to more accurately control the radius of the adhesive tape roll after winding by the winding roller 3, a scale is arranged on the connecting frame 4 to assist the adjustment of the limiting assembly 6. The position of the scale can be located on any vertical side wall of the connecting frame 4, or even the scale can be arranged on the sliding groove 40, as long as its position is convenient for the staff to directly observe.

[0028] Specifically, the sum of the radius of the winding roller 3 and the radius of the extrusion roller 5 is greater than the vertical height from the center of the winding roller 3 to the lower end of the sliding groove 40. The relationship between the radius of the winding roller 3 and the radius of the extrusion roller 5 and the vertical height from the winding roller 3 to the lower end of the sliding groove 40 is to ensure that the extrusion roller 5 can contact the winding roller 5 when the extrusion roller 5 is located at the lowermost end of the sliding groove 40, so as to avoid the problem that the extrusion roller 5 cannot contact the adhesive tape on the winding roller 3 in the initial winding stage.

[0029] Embodiment Two

[0030] Please refer to the accompanying drawings Figure 3

[0031] In view of the fact that not only the bubbles in the adhesive may affect the winding effect, but also the impurity particles on the side of the adhesive tape substrate without adhesive may also affect the winding effect of the adhesive tape during the winding process, it is necessary to process the impurity particles that may exist on the adhesive tape substrate during the winding process.

[0032] Specifically, the working platform 1 is provided with a dust removal assembly 7, the dust removal assembly 7 comprises a vertical plate 70, a dust removal frame 71, a dust removal roller 72 and a plurality of elastic telescopic sleeves 73, the vertical plate 70 is fixedly connected to the working platform 1, one end of the elastic telescopic sleeve 73 is fixedly connected to the vertical plate 70, the other end is fixedly connected with the dust removal frame 71, the dust removal roller 72 is bearingly connected to the dust removal frame 71, and the dust removal roller 72 is in contact with the winding roller 3; the dust removal roller 72 is in contact with the adhesive-free side of the adhesive tape base material on the winding roller 3 and completes the removal of impurity particles thereon, so that the impurities do not enter the adhesive of other sections of the adhesive tape during subsequent winding, and the type of the dust removal roller 72 can be selected according to actual conditions, for example, a dust removal roller 72 with a brush on the surface is used, and meanwhile, considering that the radius of the adhesive tape roll is continuously expanded during the winding of the adhesive tape, the elastic telescopic sleeve 73 is used to connect the dust removal frame 71 and the vertical plate 70, so that the position of the dust removal roller 72 is variable, and it should be noted that the dust removal assembly 7 should be arranged behind the winding roller 3, that is, the adhesive tape is in contact with the winding roller 3 first and then with the dust removal assembly 7, and it should be noted that if the radius of the adhesive tape roll after winding by the winding roller 3 is large, it means that the telescopic length of the elastic telescopic sleeve 73 is long, and considering that the gravity of the elastic telescopic sleeve 73 may affect normal telescoping when the length of the elastic telescopic sleeve 73 is too long, the position of the dust removal assembly 7 can be changed so that it is located directly below the winding roller 3, that is, the elastic telescopic sleeve 73 is in a vertical state.

[0033] Specifically, the surface of the dust removal roller 72 is attached with liquid silicone; in the utility model, the liquid silicone is coated on the surface of the dust removal roller 72 to adhere the impurity particles on the adhesive tape base material, and compared with the mechanical removal of the impurity particles, the liquid silicone has the advantage that the impurity particles are adhered to the dust removal roller 72 after being removed, and the problem that the impurity particles are scattered on the working platform 1 does not occur, and the impurity particles do not need to be collected, but the impurity particles on the dust removal roller 72 will gradually increase with the use time, so the liquid silicone layer on the surface of the dust removal roller 72 or the dust removal roller 72 needs to be replaced regularly by the staff.

[0034] The above is only a preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
