Description

Technical Field

[0001] The utility model relates to the technical field of labeling machines, in particular to a label pressing mechanism and a labeling machine. Background Art

[0002] A labeling machine is a device that uses adhesive to stick paper or metal foil labels on specified packaging containers. When the sensor sends a signal that the label object is ready to be labeled, the drive wheel on the labeling machine rotates. Since the roll label is in a tensioned state on the device, when the base paper is close to the peeling plate and changes direction, the label has a certain degree of stiffness, and the front end is forced to detach and prepare for labeling. At this time, the label object is just under the label, and under the action of the labeling wheel, synchronous labeling is achieved. After labeling, the sensor under the roll label sends a signal to stop running, the drive wheel stops, and a labeling cycle ends.

[0003] Conventional label pressing mechanisms use a relatively fixed structure to assist in pressing the label tape, and the flexibility and adjustability of the structure are relatively limited, which can easily cause the label tape to wrinkle when the label tape is pressed.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a label pressing mechanism and a labeling machine are proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a label pressing mechanism and a labeling machine to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a label clamping mechanism and a labeling machine, comprising a clamping assembly and an auxiliary frame group, an auxiliary roller is horizontally installed on one side of the clamping assembly, the auxiliary frame group is connected to the side of the clamping assembly, and a recovery frame is vertically installed on one side of the auxiliary frame group, the auxiliary frame group comprises a support frame, a self-resetting hinge, a scraper and a tensioning roller, a self-resetting hinge is installed on one side of the support frame, and a scraper is connected to the side of the self-resetting hinge away from the support frame, and a tensioning roller is installed on the side of the support frame away from the self-resetting hinge.

[0007] Furthermore, the clamping assembly includes a clamping roller, a counterweight slider, and a device frame. The left and right ends of the clamping roller are connected to the counterweight slider, and the side of the counterweight slider away from the clamping roller is connected to the device frame.

[0008] Furthermore, the clamping assembly also includes a spring damping column and a fixing seat. The spring damping column is vertically installed on the top of the counterweight sliding block, and the fixing seat is installed on the top of the spring damping column.

[0009] Furthermore, the counterweight sliding block is slidably connected to the device frame, and the fixing seat is fixed to one side of the top of the device frame, and the auxiliary roller is connected to the side of the device frame away from the recovery frame.

[0010] Furthermore, the tensioning roller is horizontally installed at the bottom of the support frame away from the reset hinge, and both sides of the support frame are slidably connected to the device frame.

[0011] Furthermore, the recovery frame includes an automatic winding roller, a slide seat and a fixed frame. The slide seats are installed on the left and right ends of the automatic winding roller, and one side of the slide seat is slidably connected to the fixed frame.

[0012] Furthermore, the fixing frame is vertically mounted on the top of one side of the support frame away from the self-resetting hinge, and the slide seat is used for the automatic winding roller to translate up and down on the surface of the fixing frame.

[0013] A labeling machine is provided with the label pressing mechanism as described above.

[0014] The utility model provides a label pressing mechanism and a labeling machine, which have the following beneficial effects:

[0015] 1. The utility model has an auxiliary roller horizontally mounted between the left and right device frames, and a tensioning roller horizontally mounted at the lower end of one side of the support frame, and the support frame is movable and adjustable for vertical lifting and translation on the surface of the device frame. When the label belt passes around the tensioning roller from top to bottom, it passes around the upper side of the auxiliary roller from bottom to top, and then passes around the bottom of the pressing roller from top to bottom. While assisting the pressing roller to transport the label belt at its bottom, the structure's mobility can be used to achieve tension adjustment, so as to ensure that the pressing roller presses the label and can ensure the overall flatness of the label belt as much as possible while transporting and tightening it, so as to prevent unnecessary problems such as wrinkles during the pasting process.

[0016] 2. The utility model installs a self-resetting hinge on one side of the support frame and connects a scraper by the self-resetting hinge, so that after the pressure roller presses the label onto the surface of the material, when passing through the bottom of the scraper, the structural downward pressure provided by the self-resetting hinge allows the scraper to be adaptively adjusted according to the undulating structure of the material surface while pressing and scraping the material surface, without affecting the scraping and pressing of the label on the material surface, and can also ensure the firmness and flatness of the label pasting. In addition, since the scraper is connected to one end of the support frame by the self-resetting hinge, it can be synchronously adjusted with the vertical lifting and lowering adjustment of the support frame, which ensures the structural integrity while having sufficient structural flexibility.

[0017] 3. The utility model symmetrically installs a counterweight slider and a spring damping column at the left and right ends of the pressure roller, wherein the structural mass of the counterweight slider and the downward pressure of the spring damping column are utilized to enable the pressure roller to provide a pressing effect on the label as much as possible. At the same time, the elastic telescopic structure of the spring damping column itself can enable the pressure roller to automatically adjust in the vertical direction according to the undulating structure of the material surface without affecting the downward pressure of the structure. In addition, through the structural sliding property between the counterweight slider and the device frame, the pressure roller can use the spring damping column to perform vertical lifting and lowering adjustment while ensuring the overall left and right stability as much as possible to prevent the label from being pressed inadequately.

DETAILED DESCRIPTION

[0023] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0024] like Figures 1 to 4As shown, a label pressing mechanism and a labeling machine include a pressing component 1 and an auxiliary frame group 3, an auxiliary roller 2 is horizontally installed on one side of the pressing component 1, the auxiliary frame group 3 is connected to the side of the pressing component 1, and a recovery frame 4 is vertically installed on one side of the auxiliary frame group 3, the auxiliary frame group 3 includes a support frame 301, a self-resetting hinge 302, a scraper 303 and a tensioning roller 304, a self-resetting hinge 302 is installed on one side of the support frame 301, and the side of the self-resetting hinge 302 away from the support frame 301 is connected to A scraper 303 is provided, and a tensioning roller 304 is installed on the side of the support frame 301 away from the self-resetting hinge 302. Through the adjustable vertical lifting and translation of the support frame 301 on the surface of the device frame 103, when the label belt passes around the tensioning roller 304 from top to bottom, it passes around the upper side of the auxiliary roller 2 from bottom to top, and then passes around the bottom of the pressure roller 101 from top to bottom, the tension adjustment can be realized by utilizing the activity of the structure while assisting the pressure roller 101 to transport the label belt at its bottom.

[0025] like Figures 1 to 4 As shown, the clamping assembly 1 includes a clamping roller 101, a counterweight slider 102, and a device frame 103. The left and right ends of the clamping roller 101 are connected to the counterweight slider 102, and the side of the counterweight slider 102 away from the clamping roller 101 is connected to the device frame 103. The clamping assembly 1 also includes a spring damping column 104 and a fixed seat 105. The top of the counterweight slider 102 is vertically installed with the spring damping column 104, and the top of the spring damping column 104 is installed with the fixed seat 105. The counterweight slider 102 is slidably connected to the device frame 103, and the fixed seat 105 is fixed to one side of the top of the device frame 103, and the auxiliary roller 2 is connected to the side of the device frame 103 away from the recovery frame 4. A self-resetting hinge 302 is installed on one side of the support frame 301, and the scraper 303 is connected by the self-resetting hinge 302. After the pressing roller 101 presses the label onto the surface of the material, when it passes through the bottom of the scraper 303, the structural downward pressure provided by the self-resetting hinge 302 allows the scraper 303 to scrape the surface of the material while being able to perform adaptive adjustment according to the undulating structure of the material surface.

[0026] like Figures 1 to 4As shown, the tensioning roller 304 is horizontally installed at the bottom of the support frame 301 away from the self-resetting hinge 302, and both sides of the support frame 301 are slidably connected to the device frame 103. The recovery frame 4 includes an automatic winding roller 401, a slide 402 and a fixed frame 403. The left and right ends of the automatic winding roller 401 are installed with a slide 402, and one side of the slide 402 is slidably connected with the fixed frame 403. The fixed frame 403 is vertically installed at the top of the side of the support frame 301 away from the self-resetting hinge 302, and the slide 402 is used for the automatic winding roller 401 to translate up and down on the surface of the fixed frame 403. By utilizing the structural mass of the counterweight slider 102 itself and the downward pressure of the spring damping column 104 itself, the clamping roller 101 can provide a pressing effect on the label as much as possible. At the same time, the elastic telescopic structure of the spring damping column 104 itself can enable the clamping roller 101 to automatically adjust in the vertical direction according to the undulating structure of the material surface.

[0027] A labeling machine is provided with the label clamping mechanism as described above. By arranging a tensioning roller 304 on one side of a support frame 301 and using an auxiliary roller 2, the label can be tensioned while being transmitted to ensure the flatness of the label during subsequent pasting. In addition, the label belt can be clamped by using a clamping roller 101 and a spring damping column 104, and can be appropriately adjusted within a certain range according to the structure of the material surface. The use of a self-resetting hinge 302 and a scraper 303 can cooperate with the use of the clamping roller 101 to further assist in horizontal scraping after the label is pasted to ensure the firmness of the pasting.

[0028] In summary, if Figures 1 to 4 As shown, when the label pressing mechanism and the labeling machine are used, one end of the label tape delivered thereto by the upstream structure first passes around the tensioning roller 304 from top to bottom, then passes around the upper side of the auxiliary roller 2 on one side of the support frame 301 from bottom to top, and then passes around the bottom of the pressing roller 101 from top to bottom. After passing around the bottom of the pressing roller 101, it is finally wound onto the surface of the automatic winding roller 401 installed on one side of the fixing frame 403 by means of the slide 402;

[0029] As the automatic winding roller 401 operates, the label tape is conveyed, and the tensioning roller 304 on one side is driven to translate under the movement of the support frame 301, and the structure of the pressure roller 101 and the auxiliary roller 2 cooperates to achieve the effect of tensioning the label tape, so that the pressure roller 101 can press the label tape;

[0030] At the same time, by utilizing the structural mass of the counterweight slider 102 and the downward pressure of the spring damping column 104, the pressing roller 101 can be flexibly adjusted according to the different surface structures of the materials below.

[0031] The activity of the structure can be used to achieve tension adjustment while assisting the pinch roller 101 to convey the label tape at the bottom thereof. At the same time, as the support frame 301 is vertically lifted and translated on the surface of the device frame 103, the activity of the structure can be used to achieve tension adjustment while assisting the pinch roller 101 to convey the label tape at the bottom thereof.

[0032] When the material with a label on its surface passes through the bottom of the scraper 303, the structural downward pressure provided by the self-resetting hinge 302 allows the scraper 303 to scrape the material surface while adaptively adjusting according to the undulating structure of the material surface to ensure the tightness of the label.

[0033] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
