Description

Technical Field

[0001] This application relates to the field of label processing equipment technology, and in particular to an integrated label conveying and cutting device. Background Technology

[0002] Labels, as an important carrier of product identification and information transmission, are widely used in many industries such as packaging, logistics, and electronics. To improve production efficiency, automated label cutting equipment has emerged, which can typically achieve continuous fixed-length cutting of rolls of label tape.

[0003] Existing label cutting devices typically use a conveyor to feed the label tape to a predetermined position, where a cutting blade performs the cutting action. To ensure the accuracy of the cutting position, some devices apply simple mechanical clamping to the label tape before cutting, such as using pressure rollers or blocks for fixation.

[0004] However, this simple mechanical clamping method has inherent structural defects. Because the label tape itself is thin and has a certain degree of elasticity, a single mechanical pressure point cannot completely eliminate the minute vibrations or warping that occur when the label contacts the cutting tool. Especially when cutting at high speeds or handling labels made of harder materials, this minute displacement can lead to uneven cuts and reduced dimensional accuracy, directly affecting product quality.

[0005] Therefore, this utility model proposes an integrated label conveying and cutting device to overcome the shortcomings of the prior art. Utility Model Content

[0006] The purpose of this application is to provide an integrated label conveying and cutting device, which aims to improve the problem that some integrated label conveying and cutting devices have a single method of fixing the label at the moment of cutting, which is prone to low cutting accuracy due to label vibration or warping.

[0007] This utility model provides an integrated label conveying and cutting device, including: a base, and a transmission mechanism disposed on the top of the base; the transmission mechanism includes a conveying wheel and a cutter; and a limiting component that is vertically and flexibly disposed above the conveying wheel.

[0008] The limiting components include a cylinder and a chassis fixedly connected to the cylinder output end; a vacuum suction cup is fixedly connected to the lower surface of the chassis, and a conveying roller is rotatably connected to the outer side of the chassis.

[0009] Furthermore, the lower surface of the conveyor roller is positioned opposite to the upper surface of the conveyor wheel, and the limiting component can be lowered by the drive of the cylinder to achieve the pressing and fixing of the label.

[0010] Preferably, it also includes a distance sensor and a guide rail. The distance sensor is slidably connected to the guide rail, and the guide rail is fixed to the base. The position of the distance sensor can be adjusted by a position adjustment mechanism to achieve precise positioning of the label.

[0011] Preferably, when the cylinder drives the chassis to descend, the vacuum suction cup and the conveying roller move down synchronously. This linkage structure can simultaneously achieve adsorption and rolling fixation of the label tape, forming a double pressing effect and further improving the reliability of fixation.

[0012] Preferably, it also includes a limiting mechanism located at the beginning of the transmission path at the top of the base, for initially elastically limiting the label tape entering the transmission mechanism to accommodate materials of different thicknesses.

[0013] Preferably, the limiting mechanism includes a bracket fixed to the base, a limiting rod that can slide up and down through the bracket, and the upper end of the limiting rod is elastically pressed by a spring, while the lower end of the limiting rod is rotatably connected to a roller.

[0014] Preferably, the outer circumferential surface of the roller contacts the label tape. When the thickness of the label tape changes, the roller drives the limiting rod to move up and down and compress or release the spring, thereby achieving adaptive compression of labels of different thicknesses through a purely mechanical structure.

[0015] Preferably, in order to ensure the smoothness of the conveying process and prevent the label tape from deviating, the rotation axis of the conveyor roller is set parallel to the rotation axis of the conveyor wheel.

[0016] In summary, this application includes at least one of the following beneficial technical effects: 1. This utility model solves the problem of unstable label fixation and easy displacement leading to low precision during cutting in the prior art by setting a limiting component driven by a cylinder and integrating a vacuum suction cup and a conveying roller. It achieves the technical effect of firmly fixing the label through the dual action of vacuum adsorption and mechanical rolling, which significantly improves the stability and accuracy of cutting.

[0017] 2. This utility model solves the problem of existing devices being difficult to be compatible with labels of different thicknesses and having poor versatility by setting an elastic adaptive limiting mechanism composed of springs and rollers. It achieves the technical effect of automatically adapting to changes in material thickness and applying a stable clamping force, thus broadening the applicability of the device.

[0018] 3. This utility model integrates precise conveying, dual fixing and adaptive limit functions into one, which solves the problems of low automation and single function in the prior art. It achieves the technical effect of compact structure, automated process and reliable operation, and improves the overall efficiency of label processing. Attached Figure Description

[0020] The following is in conjunction with the appendix Figure 1 - Appendix Figure 4 This application will be described in further detail below.

[0021] Example: Reference Figures 1 to 4 This utility model provides an integrated label conveying and cutting device, which aims to solve the problem of low cutting accuracy caused by unstable fixing of labels during the cutting process in the prior art.

[0022] like Figure 1 and Figure 2 As shown, an integrated label conveying and cutting device includes a base 1 and a transmission mechanism 2 fixedly connected to the top of the base 1. The base 1 is used to provide a mounting base for the entire device, and the transmission mechanism 2 is used to realize the label conveying and cutting functions. The transmission mechanism 2 includes a conveying wheel 21 for active conveying and a cutter 22 set on the label conveying path.

[0023] It also includes a limiting component 3 that is vertically mounted above the conveyor wheel 21, and the limiting component 3 and the aforementioned transmission mechanism 2 form a specific structural fit and connection relationship, which is used to stably and reliably press and fix the label tape at the moment of cutting.

[0024] Reference Figure 1 and Figure 3The limiting component 3 includes a cylinder 31 that provides vertical driving force, and a chassis 32 that is fixedly connected to the cylinder 31 through its output end. A vacuum suction cup 33 is fixedly connected to the lower surface of the chassis 32 for fixing the label tape by negative pressure adsorption. At the same time, a conveying roller 34 is rotatably connected to the outer side of the chassis 32. The lower surface of the conveying roller 34 is opposite to the upper surface of the conveying wheel 21 to form a clamping point for clamping the conveyed label tape. Driven by the cylinder 31, the composite clamping structure integrating the vacuum suction cup 33 and the conveying roller 34 can firmly fix the label tape on the working plane before the cutter 22 starts working through the dual action of vacuum adsorption and roller rolling, ensuring high stability and accuracy during the cutting process.

[0025] Reference Figure 2 The transmission mechanism 2 also includes a distance sensor 24, which is slidably connected to the guide rail 25 and the guide rail 25 is fixed on the base 1. The distance sensor 24 is driven by the position adjustment mechanism 23, so that it slides on the guide rail 25 to adjust the detection position.

[0026] Reference Figure 3 The vacuum suction cup 33 and the conveying roller 34 are both mounted on the same chassis 32 driven by the cylinder 31. This structural layout ensures that when the cylinder 31 is activated, the vacuum suction cup 33 and the conveying roller 34 can move down synchronously, thereby applying both adsorption force and rolling force to the label tape at the same time.

[0027] Reference Figure 1 and Figure 4 It also includes a limiting mechanism 4 set at the beginning of the transmission path at the top of the base 1. The limiting mechanism 4 is used to elastically limit the label tape entering the transmission mechanism 2. Specifically, the limiting mechanism 4 includes a bracket 41 fixed on the base 1. A spring 42 and a limiting rod 43 are provided in the bracket 41. The limiting rod 43 can slide up and down through the bracket 41, and the upper end of the limiting rod 43 is elastically pressed by the spring 42. The lower end of the limiting rod 43 is rotatably connected to a roller 44. The outer circumferential surface of the roller 44 is used to directly contact and press the label tape. When encountering label tapes of different thicknesses, the roller 44 will drive the limiting rod 43 to move up and down, thereby compressing or releasing the spring 42, realizing automatic adjustment of the pressing force. The rotation axis of the conveying roller 34 is parallel to the rotation axis of the conveying wheel 21. This parallel arrangement ensures that the driving force applied by the two rollers to the label tape is uniform and in the same direction.

[0028] Working principle: When the label needs to be conveyed and cut, the label tape first passes through the limiting mechanism 4. Due to the elastic pressure applied to the label tape by the roller 44 under the action of the spring 42, label tapes of different thicknesses can be smoothly pressed and fed into the transmission mechanism 2. Then, the conveying wheel 21 and the conveying roller 34 rotate together to convey the label tape forward. When the distance sensor 24 detects the preset cutting position, the conveying wheel 21 and the conveying roller 34 stop rotating.

[0029] After the conveying stops, the cylinder 31 of the limiting component 3 is activated, driving the chassis 32 to descend rapidly. This causes the vacuum suction cup 33 and the conveying roller 34 below the chassis 32 to act simultaneously on the surface of the label tape. The vacuum suction cup 33 generates negative pressure adsorption force, and the conveying roller 34 applies mechanical rolling force. Through this dual fixing method combining adsorption and rolling, the label tape is firmly locked in the cutting position. At this time, the cutter 22 cuts the fixed label tape. Through the synergistic effect of the limiting component 3, this utility model effectively solves the problem of low cutting accuracy caused by unstable fixing in the prior art.
