Description

Technical Field

[0001] This utility model relates to a labeling machine, specifically, to a fast labeling machine with a material discharge function. Background Technology

[0002] A labeling machine is a mechanical device that automatically affixes labels to products. Its core working principle is as follows: the feeding mechanism 2 conveys the items through the conveyor belt, and the labeling mechanism 3, through the coordinated action of the unwinding shaft 32, the rewinding shaft 33 and the labeling wheel on the mounting frame 31, makes the belt move intermittently under tension control to affix the labels to the items. Then the feeding mechanism 2 conveys the items and then the discharging mechanism 5 discharges the items from the feeding mechanism 2.

[0003] In practical applications, the stability of the take-up and unwinding system is crucial. The take-up shaft 32 is usually equipped with a rubber or silicone friction sleeve to increase the friction with the paper roll core. However, the friction sleeve will wear and age over time, and the surface will become smooth, causing slippage during the take-up process. This will result in the take-up length being shorter than the theoretical value, causing label tape redundancy. At the same time, if the label tape released by the unwind shaft 32 is too long, it will further aggravate the loosening of the tape. The instability of take-up and unwinding will eventually be transmitted to the labeling station, causing problems such as inaccurate label placement and wrinkling. When the existing labeling machine is tightening the loose label tape, it is often necessary to stop the labeling machine and have the operator manually tighten the label tape before restarting the labeling machine. This process frequently interrupts the operation of the labeling machine and affects the overall efficiency of the labeling machine. In view of this, we propose a fast labeling machine with a material discharge function. Utility Model Content

[0004] The purpose of this invention is to provide a fast labeling machine with a material discharge function to solve the problems mentioned in the background art, such as inaccurate label placement and wrinkling caused by loose label tape.

[0005] To address the aforementioned problems, the present invention aims to provide a rapid labeling machine with a discharge function, comprising a base, a feeding mechanism and a labeling mechanism on the upper side of the base, the labeling mechanism being located on one side of the feeding mechanism and vertically arranged therebetween, the feeding mechanism conveying the item to the position corresponding to the labeling mechanism, the labeling mechanism affixing the label to the surface of the item, a discharge mechanism being located on one side of the feeding mechanism to discharge the labeled item, a tensioning mechanism being located near the unwinding shaft of the mounting frame, the tensioning mechanism being used to tension the label tape, the tensioning mechanism comprising an adjusting component, a coil spring and a transmission component, the adjusting component and the transmission component being located near the top of the side wall of the mounting frame, the coil spring being located inside the adjusting component, the adjusting component, the coil spring and the transmission component being connected together, when the coil spring is in the winding state, the coil spring unwinds and drives the transmission component to rotate, thus tensioning the label tape.

[0006] As a further improvement to this technical solution, the adjustment assembly includes a mounting shell rotatably connected to the mounting bracket at a position away from the top of the unwinding shaft. The mounting shell has a mounting groove inside, and the coil spring is located inside the mounting groove. The outer end of the coil spring is fixedly connected to the inner wall of the mounting groove.

[0007] As a further improvement to this technical solution, the transmission assembly includes a rotating rod rotatably connected inside the mounting groove via a bearing. The inner end of the coil spring is fixedly connected to the circumferential surface of the rotating rod. When the coil spring is in a coiled state, the coil spring relaxes and drives the rotating rod to rotate.

[0008] As a further improvement to this technical solution, one end of the rotating rod passes through the side wall of the mounting shell and the mounting bracket and is fixedly connected to a connecting plate. The rotating rod drives the connecting plate to rotate.

[0009] As a further improvement to this technical solution, the end of the connecting plate away from the rotating rod is rotatably connected to a guide roller via a bearing. The rotating connecting plate drives the guide roller to move so that it tensions the label tape.

[0010] As a further improvement to this technical solution, a ratchet is coaxially fixedly connected to the circumferential surface of the mounting shell near the mounting bracket, and a pawl is slidably connected to the top of the mounting bracket near the side of the mounting shell. When the pawl engages with the ratchet, it restricts the position of the mounting shell to prevent it from rotating.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This high-speed labeling machine with material discharge function uses a coil spring that remains wound up during operation to provide tension. This tension drives the rotating rod and connecting plate to rotate. The rotating connecting plate moves the guide roller to apply tension to the label tape, keeping it taut. When the slack of the label tape exceeds the maximum compensation stroke of the guide roller, the preload of the coil spring cannot eliminate the slack. The operator rotates the mounting shell to further wind up the outer end of the coil spring to increase its preload. At this time, the expansion of the coil spring's relaxation stroke allows the guide roller to have a larger movement distance, re-tensioning the excessively slack label tape. Tension compensation can be completed without stopping the machine, improving the continuous operation efficiency and overall production of the labeling machine, and increasing the utilization efficiency of the labeling machine.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] Please see Figure 1 - Figure 5As shown, the purpose of this embodiment is to provide a fast labeling machine with a material discharge function, including a base 1. A feeding mechanism 2 and a labeling mechanism 3 are provided on the upper side of the base 1. The labeling mechanism 3 includes a mounting frame 31 fixedly connected to the base 1. A unwinding shaft 32, a rewinding shaft 33, several limiting shafts, and labeling wheels are rotatably connected to the side of the mounting frame 31 near the feeding mechanism 2. A baffle is bolted to the end of the unwinding shaft 32 away from the mounting frame 31. When using the labeling machine, the operator removes the baffle and places the label roll onto the unwinding shaft 32. Then, the operator installs the baffle back onto the unwinding shaft 32 to fix the label roll. After the label is secured, the worker pulls one end of the label tape through the limiting shaft and the labeling wheel, and fixes it on the take-up shaft 33. The unwinding shaft 32 rotates to unwind the label tape, while the take-up shaft 33 rotates to rewind the label tape. The labeling mechanism 3 is located on one side of the feeding mechanism 2 and is perpendicular to the feeding mechanism 2. A limiting rod is fixedly connected to the top side of the feeding mechanism 2. The limiting rod prevents the item from sliding down the feeding mechanism 2, so that the label tape is parallel to the surface of the item, making it easier for the label to be applied to the surface of the item. The feeding mechanism 2 and the labeling mechanism 3 are existing technologies, and this solution does not improve them, so they will not be described here.

[0027] A tensioning mechanism 4 is provided on the mounting frame 31 near the unwinding shaft 32. The tensioning mechanism 4 is used to tension the label tape to prevent the label tape from becoming loose during use and affecting the use of the labeling mechanism 3. After the feeding mechanism 2 transports the item to the position corresponding to the labeling mechanism 3, the feeding mechanism 2 stops working and the item is stationary. At this time, the item and the labeling mechanism 3 are in the same position. The labeling mechanism 3 affixes the label to the surface of the item. A discharge mechanism 5 is provided on one side of the feeding mechanism 2. After the item is labeled, the feeding mechanism 2 transports the item toward the direction close to the discharge mechanism 5. The discharge mechanism 5 discharges the labeled item.

[0028] The tensioning mechanism 4 includes an adjusting component, a coil spring 45, and a transmission component. The adjusting component and the transmission component are located on the side wall of the mounting bracket 31 near the top. The coil spring 45 is located inside the adjusting component. The adjusting component, the coil spring 45, and the transmission component are connected together. During the process of the label tape being wound on the labeling mechanism 3, the operator winds up the coil spring 45. When the coil spring 45 is in the wound state, the torque of the coil spring 45 itself drives the transmission component to rotate, thus tensioning the label tape and preventing the label tape from becoming loose and affecting the label application.

[0029] refer to Figure 3 - Figure 5The adjustment assembly includes a mounting housing 41 rotatably connected to the mounting frame 31 at a position away from the top of the unwinding shaft 32. The mounting housing 41 has a mounting groove inside, and a coil spring 45 is located inside the mounting groove. The outer end of the coil spring 45 is fixedly connected to the inner wall of the mounting groove. A ratchet 46 is coaxially fixedly connected to the circumferential surface of the mounting housing 41 near the mounting frame 31. A pawl 47 is slidably connected to the top of the mounting frame 31 near the mounting housing 41. When the pawl 47 engages with the ratchet 46, it restricts the position of the mounting housing 41 to prevent it from rotating, thus preventing the coil spring 45 from rotating when it relaxes, which would cause the coil spring 45 to loosen and affect its ability to drive the transmission assembly to rotate.

[0030] The transmission assembly includes a rotating rod 42 rotatably connected to the mounting groove via a bearing. The inner end of a coil spring 45 is fixedly connected to the circumferential surface of the rotating rod 42. When the coil spring 45 is in a coiled state, the outer end of the coil spring 45 remains stationary under the constraint of the mounting shell 41. At this time, the inner end of the coil spring 45 rotates, causing the coil spring 45 to relax and drive the rotating rod 42 to rotate. One end of the rotating rod 42 passes through the side wall of the mounting shell 41 and the mounting bracket 31 and is fixedly connected to a connecting plate 43. The rotating rod 42 drives the connecting plate 43 to rotate. The end of the connecting plate 43 away from the rotating rod 42 is rotatably connected to a guide roller 44 via a bearing. The rotating connecting plate 43 drives the guide roller 44 to move so that it tensions the label tape.

[0031] A positioning shell 471 is fixedly connected to the side of the mounting bracket 31 near the mounting shell 41. A pawl 47 is slidably connected inside the positioning shell 471. A compression spring 472 is fixedly connected inside the positioning shell 471, connecting the positioning shell 471 and the pawl 47 together. The compression spring 472 pushes the pawl 47 to extend from one end of the positioning shell 471, allowing the pawl 47 to contact the ratchet 46 and position the ratchet 47. Simultaneously, a protrusion is fixed to the side wall of the pawl 47, extending from inside the positioning shell 471. The positioning shell 471 has a slot for the protrusion to slide. When the preload of the coil spring 45 cannot be dissipated... When the label tape becomes loose, the operator pulls the protrusion to move the pawl 47 away from the ratchet 46. The pawl 47 then enters the positioning housing 471 and compresses the compression spring 472. At this point, the pawl 47 separates from the ratchet 46, releasing its restriction on the ratchet 46. Subsequently, the operator rotates the mounting housing 41, causing the outer end of the coil spring 45 to rotate. The rotating mounting housing 41 further winds up the coil spring 45, increasing its elastic torque. Once the coil spring 45 is wound up, it can release greater torque, thus allowing the loose label tape to be re-tensioned without stopping the labeling machine. This improves the continuous operation efficiency and overall production of the labeling machine.

[0032] When using this device:

[0033] The staff used a wrench to tighten the bolts to remove the baffle at the end of the unwinding shaft 32. Then, the staff put the label on the unwinding shaft 32 and used bolts to install the baffle at the end of the unwinding shaft 32 to fix the label. After the label is fixed, the staff pulled one end of the label around the guide roller 44, the limit shaft and the labeling wheel and fixed it to one end of the take-up shaft 33.

[0034] During the label wrapping process, the coil spring 45 is in a coiled state. When the label wrapping is completed, the coil spring 45 unwinds, causing the rotating rod 42 and the connecting plate 43 to rotate, which in turn causes the guide roller 44 to move and tighten the label tape.

[0035] When the labeling mechanism 3 needs to label the items, the conveyor belt on the feeding mechanism 2 rotates to transport the items. During the movement of the items, the items slide along the axis of the limit rod. When the items move to the bottom of the labeling mechanism 3, the conveyor belt stops rotating to keep the items stationary. At this time, the labeling mechanism 3 affixes the label to the items.

[0036] After the items are labeled, the conveyor belt rotates and transports the items to the discharge mechanism 5. The discharge mechanism 5 removes the items. During the movement of the items, the unwinding shaft 32 and the rewinding shaft 33 rotate synchronously to unwind and rewind the label tape, changing the position of the label on the label tape so that the label can be affixed to the items later.
