[0023] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0024] The following will describe the carton binding strap releasing device in the present application in detail with reference to the accompanying drawings:

[0025] As Figure 1As shown in the figure, a device for releasing carton binding straps includes a cutting structure 1, a tape collecting clamp 2, and a cutting support unit 3. The cutting support unit 3 is located between the cutting structure 1 and the tape collecting clamp 2 to support the carton 115.

[0026] As Figure 2 shown in the figure, the cutting structure 1 includes at least one high-speed rotating grinding wheel 101 for cutting the binding strap 116. In the embodiment of the present application, the grinding wheel 101 can be selected as a diamond cutting disc, etc. The motor 102 drives the grinding wheel 101 to rotate at a high speed, so that the binding strap contacts the grinding wheel 101 and can be ground off to complete the cutting, realizing the cutting of the flexible binding strap. It is applicable not only to the cutting of the binding strap in a tight state but also to the cutting of the binding strap in a loose state.

[0027] The number and position of the grinding wheels 101 correspond to the number and position of the binding straps 116, realizing the cutting of one binding strap 116 or the one-time cutting of multiple binding straps 116. When there is only one binding strap 116, one grinding wheel 101 completes the cutting. As Figure 2 shown in the figure, when there are multiple binding straps 116, the number of grinding wheels 101 is equal to the number of binding straps 116, and the distance between adjacent grinding wheels 101 is equal to the distance between the corresponding binding straps 116. By adjusting the position of the grinding wheels 101 on the x-axis, the positions of the grinding wheels 101 and the binding straps 116 can be all aligned for the one-time cutting of multiple binding straps. For the cutting with a fixed distance between the binding straps during mechanical bundling, the efficiency of cutting the straps can be improved.

[0028] The grinding wheel 101 can move along the x-axis and y-axis directions. As Figure 2 shown in the figure, the carton binding strap cutting structure 1 further includes a fixed seat 103. The grinding wheel 101 is fixed on the fixed seat 103, and the position of the grinding wheel 101 in the x-axis direction on the fixed seat 103 can be adjusted, which is applicable to the alignment of the grinding wheel 101 and the binding strap 116 during the one-time cutting of multiple binding straps. The carton binding strap cutting structure 1 further includes a cutting fixing plate 108. The fixed seat 103 can move along the x-axis or y-axis direction on the cutting fixing plate 108, realizing the movement of the grinding wheel 101 along the x-axis or y-axis direction. Sliders 104 are arranged on the bottom plate of the fixed seat 103, and slide rails 105 and a cylinder 106 corresponding to the sliders 104 are arranged on the cutting fixing plate 108. The cylinder 106 is connected to the self-aligning connecting piece 111, and a fixing block 107 is arranged at the corresponding position on the bottom plate of the fixed seat 103. According to the direction of the slide rail 105, in the embodiment, the fixed seat 103 moves in the x-axis direction to realize the movement of the grinding wheel 101 in the x-axis direction. The cutting fixing plate 108 can move along the x-axis or y-axis direction on the horizontal plane, and the moving directions of the fixed seat 103 and the cutting fixing plate 108 are perpendicular to each other. As Figure 2As shown, sliders 109 and fixing blocks 114 are arranged on the bottom plate of the cutting fixing plate 108. The cylinder 113 is connected to the fixing block 114 through bolts 112, driving the slider 109 to move on the slide rail 110, and the bolts 112 are used for fine distance adjustment. In this embodiment, according to the direction of the slide rail 110, the cutting fixing plate 108 moves in the y-axis direction, and the distance between the grinding wheel 101 and the carton 115 can be adjusted.

[0029] In addition, the position of the cutting fixing plate 108 in the y-axis direction can be finely adjusted through the bolts 112, realizing the fine movement of the grinding wheel 101 in the y-axis direction. This is applicable to situations where the grinding wheel 101 is worn and fine adjustment of the position of the grinding wheel 101 in the y-axis direction is required.

[0030] Figure 2 The structure in... is just one of the ways of the cutting structure 1.

[0031] As Figure 3 shown, the tape collecting clamp 2 includes at least a pair of openable and closable clamping plates 201, and the contact surfaces of the clamping plates 201 are closely attached and not smooth. As Figure 4 shown, in order to clamp tightly during tape clamping, the contact surfaces of the clamping plates are closely attached. Considering that the surface of the binding tape is generally relatively smooth, in order to increase the friction between the binding tape 116 and the clamping plate 201 so that it is not easy to fall off during extraction, the contact surfaces of the clamping plate 201 are not smooth. To obtain a better anti-falling effect, the contact surface of the clamping plate 201 is a wedged tooth surface structure. In this embodiment, the tooth surface is a rectangular tooth surface, and a pointed tooth surface can also be selected. The tops 209 of the clamping plates 201 are flush and vertical, so that during the opening and closing process of the clamping plates 201, the tops 209 of the clamping plates 201 are closely attached to the carton, facilitating the clamping of the binding tape 116.

[0032] As Figure 3 shown, the clamping plates 201 move in the x-axis and y-axis directions in the horizontal plane. The clamping plate 201 includes a fixed clamping plate 202 and a sliding clamping plate 203 that moves on the x-axis, and the quantity and position of the fixed clamping plate 202 and the sliding clamping plate 203 can be adjusted. The movement of the sliding clamping plate 203 on the x-axis realizes the opening and closing of the clamping plate 201. The fixed clamping plate 202 is fixed on the tape collecting bottom plate 206, the sliding clamping plate 203 is fixed on the transmission rod 204, and the power device 205 drives the transmission rod 204 to move in the x direction through the fixing block 207 fixed on the transmission rod 204, so that the sliding clamping plate 203 moves in the x direction, realizing the opening and closing of the clamping plate 201. The tape collecting bottom plate 206 is connected to the y-axis transmission structure 208, and the tape collecting bottom plate 206 can move along the y-axis, enabling the clamping plate 201 to move in the y-axis direction and withdraw after taking the tape. Figure 3This is a feasible way for the clamping plate 201 to move along the y-axis. To clamp multiple binding straps 116, the number of fixed clamping plates 202 and sliding clamping plates 203 can be adjusted according to the number of binding straps 116. In addition, to ensure that the clamping plate 201 is aligned with the binding straps for easy clamping, the position of the fixed clamping plate 202 along the x-axis on the tape-receiving bottom plate 206 and the position of the sliding clamping plate 203 along the x-axis on the transfer rod 204 can be adjusted. When the number of clamping plates 201 is not less than 2 pairs, the distance between adjacent fixed clamping plates 202 is equal to the distance between the corresponding adjacent sliding clamping plates 203, enabling the closing of multiple pairs of clamping plates 201. When the movement of multiple sliding clamping plates 203 is controlled by the transfer rod 204, the equal spacing allows each pair of clamping plates 201 to close and clamp tightly, ensuring the reliability of clamping multiple binding straps at one time, with a simple structure. Combining Figure 1 , the spacing distance of the grinding wheel discs 101 corresponds one-to-one and is equal to the spacing distance of the binding straps 116 and the spacing distance of the clamping plates 201, enabling the one-time cutting and clamping of multiple binding straps (116).

[0033] To achieve a better pulling-out effect, the clamping plate 201 in the present application can also be located below the y-axis transfer structure 208. At this time, the tape-receiving bottom plate 206 is also located below the y-axis transfer structure 208. After the clamping plate 201 clamps and pulls out the binding strap 116, the binding strap directly falls to the floor due to gravity, avoiding the problem that the binding strap 116 falls onto the y-axis transfer structure 208 when the clamping plate 201 is above the y-axis transfer structure 208.

[0034] As Figure 1 shown, the carton binding strap releasing device in the present application further includes a cutting push plate 6. The cutting push plate 6 can expand and contract along the y-axis. The cutting push plate 6 is connected to a cylinder 601, and the pushing of the cutting push plate 6 pushes the carton 115 to the side of the cutting structure 1. The limit of the bracket 11 makes the carton 115 flush with the bracket 11. The cylinder 601 is fixed on the bracket 11 on the side of the tape-receiving fixture through a suspension beam 602. The cutting push plate 6 and the tape-receiving fixture 2 are located on the same side of the cutting support unit 3. The cutting push plate 6 pushes the carton 115 to be flush with the side of the cutting structure 1, not only making the carton 115 on the cutting side placed flat for easy cutting, but also separating the carton 115 from the binding strap 116 under the action of friction when pushing the carton 115, facilitating the clamping.

[0035] As Figure 5 shown, the cutting support unit 3 includes a support plate 301 and a vertically height-adjustable telescopic structure connected to the support plate 301. The support plate 301 is a horizontal planar structure. The telescopic structure of the cutting support unit 3 includes a guide rod 303, a cylinder 304, and a support fixing plate 305. The guide rod 303 and the cylinder 304 are both fixed on the support fixing plate 305, and the guide rod 303 is connected to the support fixing plate 305. Figure 5The telescopic structure therein is only one implementation manner for the present application to realize the lifting of the support plate 301. To make it more convenient to pull out the binding strap 116, a groove 302 may also be formed on the support plate 301 of the cutting support unit 3. When the carton 115 is incoming, the binding strap 116 is placed at the groove 302, which is convenient for pulling out the binding strap 116.

[0036] The following will describe the process of releasing the carton binding strap in combination with the above-mentioned carton binding strap releasing device:

[0037] S1. Adjust the height of the support plate 301, and place the carton 115 on the support plate 301. The cutting push plate 6 pushes the carton 115 to be flush with the bracket 11 on the side of the cutting structure 1. This not only makes the carton 115 on the side of the cutting structure 1 placed flat for cutting, but also separates the carton 115 from the binding strap 116 under the action of friction, facilitating entrainment.

[0038] S2. The cylinder 106 and the cylinder 113 jointly adjust the horizontal position of the grinding wheel 101 in the cutting structure 1 until the grinding wheel 101 contacts the binding strap 116. The motor 102 drives the grinding wheel 101 to rotate at a high speed, so that the binding strap 116 can be cut off when it contacts the grinding wheel 101, completing the cutting; when fine adjustment of the position of the grinding wheel 101 is required due to wear of the grinding wheel 101, etc., it can be adjusted by the bolt 112.

[0039] S3. The tape collecting clamp 2 moves to the working position where the clamping plate top 209 contacts the carton 115. Before moving to the working position, the sliding clamping plate 202 and the fixed clamping plate 203 are in an open state and are located on both sides of the binding strap 116; move the sliding clamping plate 202 to the closed state to complete the entrainment operation. It should be noted that the order of tape cutting and entrainment is not limited. For tightly bundled binding straps, it is suitable to cut the tape first and then entrain; for loosely bundled binding straps, it is suitable to entrain first and then cut the tape. After completing tape cutting and entrainment, the tape collecting clamp 2 retracts to the non-working position and pulls out the binding strap 116.

[0040] Using the above-mentioned carton binding strap releasing device can realize the automation of carton binding strap release, with a simple structure and low cost; the cutting method and clamping structure of the present application are applicable to the flexibility characteristics and different bundling situations of the carton binding straps; the number and distance of the grinding wheel, binding strap and clamping plate correspond to each other, realizing the one-time cutting, clamping and pulling out of multiple binding straps, and the binding strap release efficiency is high.
