Description

Technical Field

[0001] The invention relates to a rubber band wrapping device, which is used for wrapping the surface of a long strip object so that the adhesive surface of the adhesive tape on the surface of the long strip object is in close contact with the surface of the long strip object, and belongs to the technical field of wrapping equipment. Background Art

[0002] In some special occasions, it is necessary to wrap the surface of a rectangular object with a rectangular cross section with glue to achieve waterproofing and other effects. The process of wrapping with glue generally uses multiple pieces of adhesive tape coated with glue to stick on the surface of the long object in sequence, and the adhesive tape is concave on the surface of the long object. When sticking glue, in order to ensure the quality of sticking and make the adhesive surface of the adhesive tape close to the surface of the long object, it is necessary to press the surface of the long object with hands for a long time. This method is time-consuming, labor-intensive, and unstable. Especially when there are too many pieces of adhesive tape, two hands obviously cannot achieve efficient pressing of multiple pieces of adhesive tape at the same time. Summary of the invention

[0003] The purpose of the present invention is to provide a rubber band wrapping device, which can press the adhesive surface of the adhesive tape on the surface of a long strip object (i.e. the part to be wrapped) so that the adhesive tape is tightly adhered to the surface of the long strip object.

[0004] To achieve the above object, the technical solution of the present invention is:

[0005] The rubber band wrapping device comprises a material unloading rack, on which a material unloading wheel is installed, and the material unloading wheel is used to wind the rubber band. A material feeding component is also installed on the material unloading rack, and the material feeding component is used to guide the rubber band through and apply resistance to the movement of the rubber band; the material unloading rack is installed on a slide rail, and the material unloading rack is driven to move horizontally on the slide rail by a horizontal movement power device; a placing component is arranged on the side of the slide rail, and the placing component comprises a driven shaft and a driving shaft, and a long strip of the component to be wrapped is placed between the driven shaft and the driving shaft, one end of the component to be wrapped is installed on the driven shaft, and the other end of the component to be wrapped is installed on the driving shaft, and the driving shaft is driven by a rotating power device to drive the component to be wrapped to rotate.

[0006] During operation, the unloading rack is driven by the lateral force device to move horizontally on the slide rail, and continuously unloads materials to different positions of the part to be wrapped (i.e., the long strip object). At the same time, the part to be wrapped (i.e., the long strip object) rotates, wraps the rubber band on the surface of the part to be wrapped, and presses the adhesive tape on the surface of the part to be wrapped, so that the adhesive surface of the adhesive tape is tightly adhered to the surface of the long strip object. At the same time, the lateral movement speed of the unloading rack matches the rotation speed of the part to be wrapped, so as to control the shape of the rubber band wrapped on the surface of the part to be wrapped (the spacing between adjacent rubber bands), such as wrapping adjacent rubber bands at intervals, overlapping wrapping, etc.

[0007] The material feeding component is used to guide the rubber band and apply resistance to the rubber band. In this way, the rubber band is stretched before wrapping, so that the rubber band has a certain deformation. When the rubber band is wrapped, the elastic deformation of the rubber band makes the adhesive surface of the adhesive tape closely adhere to the surface of the long object. The second wheel assembly comprises a first wheel which is parallel to the first wheel and a second wheel which is parallel to the first wheel. The second wheel assembly comprises a first wheel which is parallel to the first wheel and a second wheel which is parallel to the first wheel. The first wheel assembly comprises a first wheel which is parallel to the first wheel and a second wheel which is parallel to the second wheel. The first wheel assembly comprises a first wheel which is parallel to the first wheel and a second wheel which is parallel to the second wheel. A right waist-shaped hole is formed between the two right mounting plates, a first right adjusting screw is arranged on the first right mounting plate, the first right adjusting screw extends into one end of the right waist-shaped hole, a second right adjusting screw is arranged on the second right mounting plate, and the second right adjusting screw extends into the other end of the right waist-shaped hole; one end of the second conveying shaft is located in the left waist-shaped hole, and the other end of the second conveying shaft is located in the right waist-shaped hole; in the left waist-shaped hole, one end of the second conveying shaft is located between the first left adjusting screw and the second left adjusting screw, and the first left adjusting screw and the second left adjusting screw adjust and limit one end of the second conveying shaft; in the right waist-shaped hole, the other end of the second conveying shaft is located between the first right adjusting screw and the second right adjusting screw, and the first right adjusting screw and the second right adjusting screw adjust and limit the other end of the second conveying shaft; the height of the first conveying shaft in the left vertical groove and the right vertical groove is lower than the height of the second conveying shaft in the left waist-shaped hole and the right waist-shaped hole.

[0008] In the left and right waist-shaped holes, the first left adjusting screw, the second left adjusting screw, the first right adjusting screw, and the second right adjusting screw are adjusted to adjust the position of the second conveying shaft, thereby controlling the spacing between the first conveying wheel and the second conveying wheel. The first conveying shaft is placed in the left vertical groove and the right vertical groove to facilitate the removal of the first conveying wheel, which is convenient for the rubber band to pass through. In this case, the height of the first conveying shaft in the left vertical groove and the right vertical groove is lower than the height of the second conveying shaft in the left waist-shaped hole and the right waist-shaped hole. With such an eccentric setting, the rubber band presses down the first conveying wheel during use, so that the first conveying wheel will not jump out of the left vertical groove and the right vertical groove.

[0009] Preferably, the unloading rack is mounted on a slide rail via a sliding bearing, the transverse moving power device comprises a transmission chain, the transmission chain is driven by a reduction motor, and the rotating power device is a reduction motor.

[0010] In order to facilitate the installation of components to be wrapped of different lengths, the driven shaft is installed on the driven shaft slider through a bearing, the driven shaft slider is installed on the driven shaft slide rail, and the driven shaft slider is driven by the driven shaft cylinder to move on the driven shaft slide rail. Further, the driven shaft slide rail and the driven shaft cylinder are installed on the mounting plate, and the mounting plate is installed on the mounting plate slide rail through the mounting plate slider.

[0011] In order to facilitate the installation of the component to be covered, the ends of the driving shaft and the driven shaft have pins, and both ends of the component to be covered have sockets. The driving shaft and the driven shaft are installed by inserting the pins into the sockets.

[0012] The present invention realizes wrapping a rubber band on the surface of a long strip object, and under the elastic deformation of the rubber band, the adhesive surface of the adhesive tape is closely attached to the surface of the long strip object. Under the pressure of the rubber band, the adhesive tape is ensured to be closely attached to the surface of the long strip object, thereby improving the efficiency of the attachment and reducing the error of manual operation.

[0020] The unloading frame 1 is provided with an unloading wheel 2, which is used to wind the rubber band 3 and can realize continuous rotation unloading. In order to control the speed, the unloading wheel 2 can have a certain resistance, and the unloading wheel 2 can rotate only under a certain pulling force of the rubber band 3.

[0021] The unloading rack 1 is also provided with a material feeding component 5, which is used to guide the rubber band 3 and apply resistance to the rubber band 3. Guide wheels may be provided before and after the material feeding component 5 to guide the rubber band. Figure 4 As shown, the material feeding component 5 includes a first conveying wheel 26 and a second conveying wheel 31 parallel to each other. The first conveying wheel 26 is installed on the first conveying shaft 25, and the second conveying wheel 31 is installed on the second conveying shaft 30; the two ends of the first conveying shaft 25 are respectively installed on the first left mounting plate 23 and the first right mounting plate ( Figure 4 24, and the other end of the first conveying shaft 25 is located in the right vertical groove; the first left mounting plate 23 is connected to the second left mounting plate 27, and the first left mounting plate 23 and the second left mounting plate 27 are connected together by screws 28; a left waist-shaped hole 29 is formed between the first left mounting plate 23 and the second left mounting plate 27; a first left adjusting screw 32 is provided on the first left mounting plate 23, and the first left adjusting screw 32 extends into one end of the left waist-shaped hole 29; a second left adjusting screw 33 is provided on the second left mounting plate 27, and the second left adjusting screw 33 extends into the other end of the left waist-shaped hole 29; the first right mounting plate is connected to the second right mounting plate ( Figure 4(not marked in the figure), a right waist-shaped hole is formed between the first right mounting plate and the second right mounting plate, a first right adjusting screw is arranged on the first right mounting plate, the first right adjusting screw extends into one end of the right waist-shaped hole, and a second right adjusting screw is arranged on the second right mounting plate, the second right adjusting screw extends into the other end of the right waist-shaped hole; one end of the second conveying shaft 30 is located in the left waist-shaped hole 29, and the other end of the second conveying shaft 30 is located in the right waist-shaped hole; in the left waist-shaped hole 29, one end of the second conveying shaft 30 is located between the first left adjusting screw 32 and the second left adjusting screw 33, and the first left adjusting screw 32 and the second left adjusting screw 33 adjust and limit one end of the second conveying shaft 30; in the right waist-shaped hole, the other end of the second conveying shaft is located between the first right adjusting screw and the second right adjusting screw, and the first right adjusting screw and the second right adjusting screw adjust and limit the other end of the second conveying shaft; adjust the position of the second conveying shaft 30 in the left waist-shaped hole 29 and the right waist-shaped hole, so as to adjust the spacing between the first conveying wheel 26 and the second conveying wheel 31. At the same time, the height of the first conveying axis in the left vertical groove and the right vertical groove is lower than the height of the second conveying axis in the left waist-shaped hole and the right waist-shaped hole.

[0022] The slide rail 16 is provided with a placement component, which includes a driven shaft 8 and a driving shaft 9. The driven shaft 8 and the driving shaft 9 are used to place a long strip of the component to be wrapped 6. One end of the component to be wrapped 6 is installed on the driven shaft 8, and the other end of the component to be wrapped 6 is installed on the driving shaft 9. The driving shaft 9 is driven by a rotary power device to drive the component to be wrapped 6 to rotate. The rotary power device is a reduction motor. Figure 5 As shown, the driving reduction motor of the active shaft 9 and the reduction motor driving the lateral movement of the material discharging rack can be the same reduction motor 37. The reduction motor 37 drives the transmission chain 4 to drive the lateral movement. At the same time, the reduction motor 37 drives the active shaft 9 to rotate through the pulley. The same power source is conducive to the synchronization of the lateral movement of the material discharging rack and the rotation of the active shaft.

[0023] like Figure 1 As shown, the method for installing the component 6 to be covered is as follows: the ends of the driving shaft 9 and the driven shaft 8 have plug pins 10, and both ends of the component 6 to be covered have insertion holes, and the driving shaft 9 and the driven shaft 8 are installed by inserting the plug pins 10 into the insertion holes.

[0024] In order to adapt to the components 6 to be wrapped of different lengths, the driven shaft 8 is mounted on the driven shaft slider 18 through the bearing 7, and the driven shaft slider 18 is mounted on the driven shaft slide rail 19. The driven shaft slider 18 is driven by the driven shaft cylinder 13 to move on the driven shaft slide rail 19. Further, the driven shaft slide rail 19 and the driven shaft cylinder 13 are mounted on the mounting plate 20, and the mounting plate 20 is mounted on the mounting plate slide rail 21 through the mounting plate slider 22.

[0025] When in use, the unloading wheel 2 on the unloading rack 1 rotates under the pull of the rubber band 3, and the material is continuously unloaded. After the rubber band 3 is unloaded from the unloading wheel 2, it passes through the feeding component 5, and the rubber band 3 passes between the first conveying wheel 26 and the second conveying wheel 31 of the feeding component 5, and then is wound on the component to be wrapped 6. The unloading rack 1 is driven to move horizontally on the slide rail 16 by the lateral movement force device, and continuously unloads the material to different positions of the component to be wrapped 6 (i.e., the long strip object). At the same time, the component to be wrapped 6 (i.e., the long strip object) rotates, and the rubber band 3 is wound, so that the rubber band 3 is wrapped on the component to be wrapped 6. Along the lateral movement direction of the unloading rack 1, the rubber band 3 is driven to move horizontally (move forward) while being wound, and gradually wrapped on the surface of the component to be wrapped 6, and the adhesive tape 36 on the surface of the component to be wrapped 6 is pressed, so that the adhesive surface of the adhesive tape 36 is tightly bonded to the surface of the long strip object. At the same time, the lateral movement speed of the unloading rack 1 matches the rotation speed of the component 6 to be wrapped, so as to control the shape of the rubber bands 3 wrapped on the surface of the component 6 to be wrapped (the spacing between adjacent rubber bands 3), such as the spacing between adjacent rubber bands 3, overlapping, etc. If the lateral movement speed of the unloading rack 1 is fast, the spacing between adjacent rubber bands 3 wrapped on the surface of the component 6 to be wrapped is large, that is, spacing wrapping; if the lateral movement speed of the unloading rack is slow, the spacing between adjacent rubber bands 3 wrapped on the surface of the component 6 to be wrapped is small, and adjacent rubber bands 3 even overlap (overlap).

[0026] The above embodiments do not limit the present invention in any way, and any technical solutions obtained by equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
