Description

Technical Field

[0001] This utility model relates to the field of bubble wrap packaging technology, specifically a bubble wrap tensioning device. Background Technology

[0002] In the production and processing of bubble wrap, the tensioning device plays a crucial role. As a material widely used in packaging and protection, the quality of bubble wrap directly affects the product's appearance, protective effect, and ease of use.

[0003] Existing bubble wrap tensioning devices often cannot achieve adaptive tensioning. As the bubble wrap is continuously wound up, the linear speeds of the unwinding and winding rollers will change, and traditional tensioning devices cannot automatically make corresponding adjustments. This can lead to the bubble wrap being excessively stretched or relaxed during the winding process, which in turn affects the tensioning effect of the bubble wrap and may even cause the bubble wrap to deform and break.

Detailed Implementation

[0022] This utility model embodiment provides a bubble film tensioning device, such as... Figure 1-4 As shown, the system includes a support base 101. Two slide rails 102 are fixedly mounted on the top of the support base 101. The slide rails 102 on both sides are symmetrically positioned and are L-shaped. The slide rails 102 are connected to the support base 101 by bolts. The slide rails 102 on both sides are provided with through-hole moving grooves 105. The moving grooves 105 are provided with movable sliders 103. The sliders 103 are angled and their bottoms abut against the slide rails 102. The tops of the sliders 103 on both sides are fixedly mounted with vertical moving brackets 117 on opposite sides. A moving shaft 116 is rotatably mounted between the moving brackets 117 on both sides. A columnar moving roller 118 is mounted on the outer end face of the moving shaft 116.

[0023] It should be further explained that the outer end face of the movable roller 118 is used to wrap the bubble wrap and carry out the subsequent tensioning work. A rotating motor is fixedly installed on one side of the movable bracket 117. The rotating motor is poweredly connected to the movable shaft 116. When the rotating motor is started, it can drive the movable shaft 116 to rotate, thereby driving the movable roller 118 to rotate.

[0024] Furthermore, a movable threaded shaft 119 with a crossbeam is rotatably provided in the movable slots 105 on both sides. The movable threaded shaft 119 is threadedly connected to the movable slider 103. A movable motor 109 is fixedly provided in one side wall of the movable slot 105. The movable threaded shaft 119 is poweredly connected to the movable motor 109.

[0025] It should be further explained that when the moving motor 109 is started, it can drive the moving threaded shaft 119 to rotate, and then through the threaded connection between the moving threaded shaft 119 and the moving slider 103, it drives the moving slider 103 to move in the moving groove 105. At the same time, the moving slider 103 abuts against the slide rail 102, thereby playing a moving support role and playing a role in stabilizing the movement.

[0026] Furthermore, the top of the slide rails 102 on both sides is provided with an upward-opening adjustment groove 107, and the adjustment groove 107 is provided with a vertical and movable support rod 106. The top of the movable support rods 106 on both sides is equipped with a U-shaped bracket 113 of the cross frame.

[0027] Furthermore, a support shaft 114 is rotatably provided between the U-shaped brackets 113, and a winding roller 115 is fixedly connected to the outer end face of the support shaft 114. A stress sensing sheet 112 is installed on the inner side of the U-shaped brackets 113.

[0028] It should be further explained that the stress sensing sheet 112 is a stress sensing sheet. As the length of the bubble film wrapped around the surface of the winding roller 115 increases, the diameter of the bubble film increases. When it touches the stress sensing sheet 112, that is, when the length of the bubble film wrapped around the surface of the winding roller 115 reaches its maximum, the stress sensing sheet 112 can stop the continued winding of the bubble film through signal output.

[0029] Furthermore, a U-shaped arched bracket 108 is mounted on one side of the top of the support base 101. A telescopic rod 111 is connected between the arched bracket 108 and the U-shaped bracket 113. A hydraulic telescopic device 110 is fixed on the other side of the arched bracket 108. The hydraulic telescopic device 110 is telescopically connected to the telescopic rod 111.

[0030] It should be further explained that the extension end of the hydraulic expansion joint 110 is dynamically coupled to the extension rod 111. The length of the extension rod 111 can be adjusted by hydraulic drive, thereby adjusting the translational position of the U-shaped bracket 113. By controlling the extension amount of the hydraulic expansion joint 110, the U-shaped bracket 113 can drive the support shaft 114 and the winding roller 115 to translate a distance, thereby changing the tension of the bubble film during the winding process. This ensures that the bubble film always maintains a suitable tension, avoiding problems such as loosening, wrinkling or breaking of the bubble film due to insufficient or excessive tension.

[0031] Furthermore, a stress monitor 104 is connected to the top of the movable slider 103 and between the movable support 117 and the movable roller 118. The sensing contact of the stress monitor 104 is connected to the movable shaft 116.

[0032] It should be further explained that the stress monitor 104 is used to sense and monitor the tension on the movable shaft 116. It is equipped with a high-precision tension sensor, which can detect the tension value borne by the movable shaft 116 during rotation in real time and accurately, and convert the detected tension signal into an electrical signal for output.

[0033] Furthermore, a control terminal 120 is provided on one side of the support base 101. The stress monitor 104 and the stress sensing plate 112 are both connected to the control terminal 120. The control terminal 120 is used to collect information feedback, and then to perform signal feedback according to the preset programming scheme and control the other components of the support base 101 to start and work.

[0034] When using this solution, firstly, the support base 101 is moved to the working position and its stable placement is ensured by bolts, etc., to adapt to different working environments and ground conditions. Then, the device is started, one end of the bubble wrap is fixed to the outer end face of the moving roller 118, and the bubble wrap output device is turned on, so that the bubble wrap begins to wrap around the winding roller 115. As the length of the bubble wrap wrapped on the surface of the winding roller 115 increases, the diameter of the bubble wrap becomes larger. When it touches the stress sensing plate 112, that is, when the length of the bubble wrap wrapped on the surface of the winding roller 115 reaches its maximum, the stress sensing plate 112 can output a signal to stop the continued output and wrapping of the bubble wrap.

[0035] Subsequently, one end of the bubble wrap wrapped around the surface of the winding roller 115 is fixed to the surface of the moving roller 118, and the rotating motor is turned on, thereby driving the moving roller 118 to rotate, so that the bubble wrap begins to wrap around the moving roller 118. During the wrapping process, the tension sensor inside the stress monitor 104 detects the tension value borne by the moving shaft 116 in real time and accurately, and converts the detected tension signal into an electrical signal and transmits it to the control terminal 120 for data analysis and processing.

[0036] After receiving the tension signal, the control terminal 120 analyzes and processes the tension value. If the tension value is less than the preset lower limit of the reasonable range, it indicates that the tension of the bubble film is insufficient. The control terminal 120 will immediately send a command to the moving motor 109 to start the moving motor 109 and drive the moving threaded shaft 119 to rotate. Since the moving threaded shaft 119 is threadedly connected to the moving slider 103, the rotation of the moving threaded shaft 119 will cause the moving slider 103 to move outward in the moving groove 105. The contact between the moving slider 103 and the slide rail 102 ensures the stability of the movement. At the same time, the outward movement of the moving slider 103 will push the moving bracket 117 and the moving rotating shaft 116 to move outward, thereby increasing the distance between the moving roller 118 and the bubble film output device, so that the bubble film is subjected to greater tensile force during the winding process, and the tension is improved.

[0037] In addition, the control terminal 120 will send corresponding instructions to the hydraulic expansion joint 110 according to the degree of insufficient tension, control the extension end of the hydraulic expansion joint 110 to extend, increase the length of the extension rod 111, and then drive the U-shaped bracket 113, the support shaft 114 and the winding roller 115 to translate away from the moving roller 118. This translation further adjusts the winding path of the bubble film and increases the degree of bending of the bubble film during the winding process, thereby more effectively improving the tension.

[0038] Conversely, if the control terminal 120 analyzes and finds that the tension value is greater than the preset upper limit of the reasonable range, it indicates that the current tension of the bubble wrap is too high. The control terminal 120 will send a reverse command to the moving motor 109, causing the moving motor 109 to rotate in the opposite direction, driving the moving slider 103 to move inward in the moving groove 105, thereby causing the moving shaft 116 to move inward, reducing the distance between the moving roller 118 and the bubble wrap output device, and reducing the tension of the bubble wrap. At the same time, the control terminal 120 will control the extension end of the hydraulic telescoping device 110 to retract, reducing the length of the telescoping rod 111, driving the U-shaped bracket 113, the support shaft 114 and the winding roller 115 to move towards the moving roller 118, loosening the winding path of the bubble wrap and reducing the tension.

[0039] During the continuous winding of the bubble wrap, the control terminal 120 continuously adjusts the operating status of the moving motor 109 and the hydraulic expansion joint 110 in real time based on the tension signal fed back by the stress monitor 104, to ensure that the bubble wrap always maintains a suitable tension. At the same time, the operator can also preset different tension parameters through the control terminal 120 to adapt to the winding requirements of bubble wrap of different specifications and materials, thereby realizing the output of the bubble wrap winding.
