Description

Technical Field

[0001] The utility model relates to the technical field of labeling equipment, in particular to a double-sided adhesive applying device for labels. Background Technique

[0002] At present, in the production of plastic bags, basic operations such as unwinding, intermittent cutting, heat sealing, and winding are basically automated. After winding, the plastic bags are wound into bag rolls, and the bag rolls are formed into packages by means of labeling. Among them, bag roll labeling is divided into two types: small label labeling and large label labeling. Small label labeling is a labeling method in which one or two stickers are pasted at the tail of the bag roll, which only achieves the effect of preventing the bag roll from loosening; large label labeling is a labeling method in which a rectangular label paper surrounds the outer peripheral surface of the bag roll by winding around the bag roll at least once. Because more comprehensive product and manufacturer information can be reflected on the large label, and it can provide a protective effect on the roll, it is increasingly favored by plastic bag manufacturers.

[0003] Among them, the diameter of the bag roll formed by winding the plastic bag is mostly less than 6 cm. Based on the fact that the winding of the bag roll is an automated operation, the winding speed of the bag roll is relatively fast. Relying on manual labor for large label labeling has low efficiency and high labor cost, so automatic large label labeling technology is needed for supporting operations. At present, the existing automatic large label labeling technology generally includes two steps: applying glue and labeling. The glue applying step is to stick an adhesive medium on the back of the label in advance. Using double-sided tape as the adhesive medium has obvious advantages such as cleanliness and convenience in the entire labeling process. Therefore, the existing glue applying devices are generally designed and manufactured to stick double-sided tape on the label, and its structure is as Figure 6 shown. The double-sided tape is installed on the glue applying seat in the form of a tape roll. The double-sided tape (with backing paper) released from the tape roll is used for sticking after passing through the guide wheel to the pressure roller. When applying glue, the glue body is stuck on the label, and the backing paper is wound up, and the paper winding action is synchronized when sticking the double-sided tape and stops synchronously when not sticking the double-sided tape.

[0004] In practical applications, it is found that when sticking the double-sided tape, due to the obvious bonding effect between the glue body and the label, the pressure roller mainly relies on the passive movement generated during the lateral movement of the glue applying seat to release the glue body. The speed of this passive movement and the paper winding speed often cannot be well matched, so the paper winding is often too slow or too fast. When the paper winding is too fast, it is easy to break the backing paper, resulting in the suspension of glue application; when the paper winding is too slow, the released tape is easy to become fluffy, affecting the subsequent glue application quality, and even the tape derails, which also causes the problem of glue application suspension. As Figure 6 and Figure 7 shown, although there is a way to add a floating tension wheel on the backing paper winding path to alleviate the above speed matching problem at present, this floating tension wheel will actively pull out part of the tape after one glue application, as Figure 8As shown, the front end of the colloid on the tape will cross over the rubber pressing wheel, resulting in various problems such as excessive adhesion and tape paper lifting during the next gluing and pasting. Therefore, it is necessary to improve the gluing device. Summary of the Invention

[0005] The technical problem to be solved by the present utility model is to provide a label double-sided adhesive gluing device that enables smooth gluing and is conducive to maintaining continuous gluing operation.

[0006] To solve the above technical problem, the technical solution of the present utility model is: a label double-sided adhesive gluing device, including a gluing base, a rubber pressing wheel is installed at the lower part of the gluing base, a glue supply component and a paper receiving component are respectively installed on the gluing base on the incoming tape side and the outgoing tape side of the rubber pressing wheel; a glue supply guiding wheel set and a glue cutting mechanism are installed on the gluing base between the rubber pressing wheel and the glue supply component; a movably arranged tensioning frame is installed on the gluing base between the rubber pressing wheel and the paper receiving component, a tensioning wheel is installed on the tensioning frame, and an elastic tensioner is arranged between the tensioning frame and the gluing base; a tape stopping mechanism is arranged on the gluing base on the incoming tape side of the tensioning wheel.

[0007] As a preferred technical solution, the tape stopping mechanism includes a tape stopping cylinder installed on the gluing base, and the piston end of the tape stopping cylinder is used to press the tape onto the glue supply guiding wheel set.

[0009] As a preferred technical solution, a glue cutting limiting structure for limiting the feeding position of the glue cutting knife is arranged on the gluing base.

[0010] As a preferred technical solution, the gluing base is connected with a glue spreading driving mechanism and a lifting driving mechanism.

[0011] As a preferred technical solution, the glue spreading driving mechanism includes a glue spreading transverse moving base, and the glue spreading transverse moving base is connected with a transverse moving driver; the lifting driving mechanism includes a lifting base installed on the glue spreading transverse moving base, a lifting driver is arranged between the lifting base and the glue spreading transverse moving base; the gluing base is fixedly connected with the lifting base.

[0012] As a preferred technical solution, an elastic buffer is installed between the gluing base and the glue spreading transverse moving base.

[0013] As a preferred technical solution, a transverse displacement seat is installed on the glue - spreading transverse displacement seat. The moving direction of the transverse displacement seat is arranged cross -wise with respect to the moving direction of the glue - spreading transverse displacement seat. A displacement driver is provided between the transverse displacement seat and the glue - spreading transverse displacement seat; the lifting seat is installed on the transverse displacement seat, and a lifting driver is provided between the lifting seat and the transverse displacement seat.

[0014] Due to the adoption of the above - mentioned technical solution, the label double - sided adhesive gluing device includes a gluing seat. A pressure - glue wheel is installed at the lower part of the gluing seat. A glue - supply assembly and a paper - collecting assembly are respectively installed on the gluing seat on the incoming - tape side and the outgoing - tape side of the pressure - glue wheel; a glue - supply guiding wheel group and a glue - cutting mechanism are installed on the gluing seat between the pressure - glue wheel and the glue - supply assembly; a movably - arranged tensioning frame is installed on the gluing seat between the pressure - glue wheel and the paper - collecting assembly.

When the present utility model is gluing, the tensioning wheel buffers the gluing speed of the pressure - glue wheel and the paper - collecting speed of the paper - collecting assembly. After one - time gluing is completed, the tape - stopping mechanism forcibly stops the tape on the incoming - tape side of the tensioning wheel, etc. The floating movement at the tensioning wheel stops, and it will no longer affect the output of the tape. Therefore, when gluing next time, the colloid on the tape is still in the state where the front end is under the pressure - glue wheel. When the tape - stopping mechanism releases the forced - stopping effect, the glue on the tape can be bonded in the way that the front end is sequentially pasted on the label, without problems such as redundant bonding and tape - lifting, and the gluing is smooth; circulating in this way is conducive to maintaining continuous gluing operation.

Detailed implementation manners

[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. In the following detailed description, only some exemplary embodiments of the present invention are described by way of illustration. It is understood that those of ordinary skill in the art can recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and the description are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0026] As shown in Figure 1 , Figure 2 and Figure 3 , the double-sided adhesive gluing device for labels includes a gluing base 1. A pressure rubber wheel 11 is installed at the lower part of the gluing base 1. A glue supply assembly 12 and a paper receiving assembly 13 are respectively installed on the incoming tape side and the outgoing tape side of the pressure rubber wheel 11 on the gluing base 1. When the tape 9 supplied by the glue supply assembly 12 passes through the pressure rubber wheel 11, the adhesive 92 is in the state of being below and the backing paper 91 is above. Through the downward pressure of the pressure rubber wheel 11, the adhesive 92 on the tape 9 is bonded to the label 8; the remaining backing paper 91 after bonding is wound up by the paper receiving assembly 13.

[0027] Conventionally, the glue supply assembly 12 includes a glue supply tray rotatably mounted on the glue application base 1, and a roll of glue is sleeved on the glue supply tray. The paper receiving assembly 13 includes a paper receiving tray rotatably mounted on the glue application base 1, and the paper receiving tray is connected to a paper receiving motor. The paper receiving assembly 13 realizes active winding through motor drive. The above structural principle is well-known technology in the art and will not be elaborated here.

[0028] A glue supply guide wheel set 14 and a glue cutting mechanism 2 are installed on the glue application base 1 between the pressure glue wheel 11 and the glue supply assembly 12. The glue supply guide wheel set 14 is used to guide the supply path of the tape 9, and it includes at least one glue supply guide wheel. The number and position settings of the glue supply guide wheels are easily obtained by those skilled in the art according to conventional technical means and will not be elaborated here. Among them, for the glue supply guide wheel in contact with the glue body 92 on the tape 9, anti-sticking measures should be taken on its wheel surface, such as setting an anti-sticking layer on the wheel surface or using embossing on the wheel surface.

[0029] The glue cutting mechanism 2 is used to cut off the glue body 92 when it reaches the specified length for bonding. The glue cutting mechanism 2 includes a chopping board 21 fixedly arranged on the glue application base 1 and located on the backing paper side of the tape 9. A glue cutting feed base 22 is slidably mounted on the glue application base 1 on the glue side of the tape 9. A glue cutting knife 23 corresponding to the chopping board 21 is fixedly installed on the glue cutting feed base 22, and the glue cutting feed base 22 is connected to a glue cutting driver 24.

[0030] When the glue body 92 passing through the glue cutting mechanism 2 reaches the specified length, the glue cutting driver 24 drives the glue cutting feed base 22 to move towards the chopping board 21, and the glue cutting knife 23 cuts to the position of the chopping board 21 to cut off the glue body 92. Preferably, a glue cutting limit structure 25 for restricting the feeding position of the glue cutting knife 23 is provided on the glue application base 1 to ensure that the glue cutting knife 23 can cut off the glue body 92 while avoiding cutting off the backing paper 91.

[0031] The glue-breaking limit structure 25 can be realized by a limit block, a limit rod, etc. In this embodiment, a limit rod is used for illustration. Specifically: A limit screw 26 is threadedly installed on the glue application base 1 and is arranged towards the glue-breaking feeding base 22. The end of the limit screw 26 close to the glue-breaking feeding base 22 limits the feeding position of the glue-breaking knife 23; A fastening nut 27 is installed on the limit screw 26. When the glue-breaking feeding base 22 feeds, it finally rigidly abuts against the limit screw 26. At this time, the glue-breaking knife 23 is at a feeding position where it just cuts off the colloid 92 without cutting off the backing paper 91. The use of the limit screw 26 and the setting of the fastening nut 27 enable the fastening nut 27 to be fastened to the threaded installation position of the limit screw 26 during work to fix it; After rotating the fastening nut 27 away from the threaded installation position of the limit screw 26, the limit screw 26 can rotate relative to the glue application base 1, so that the limit position can be conveniently adjusted, thereby facilitating the installation of the glue-breaking knife 23 and playing the above-mentioned glue-breaking limit role.

[0032] A tensioning frame 3 is movably installed between the glue pressing wheel 11 and the paper receiving assembly 13 on the glue application base 1. The tensioning frame 3 can be installed in a sliding manner or a swinging manner. In this embodiment, a swinging installation is used for illustration. A tensioning wheel 31 is installed on the tensioning frame 3. An elastic tensioner is provided between the tensioning frame 3 and the glue application base 1. The elastic force of the elastic tensioner drives the backing paper 91 to be tightened in a direction deviating from the paper receiving path to achieve its tensioning effect; Accordingly, when the tensioning frame 3 swings upward in the drawings of this embodiment, it plays a tensioning role on the backing paper 91.

[0033] When the paper receiving speed of the paper receiving assembly 13 is lower than the glue spreading speed of the glue pressing wheel 11, the length of the backing paper 91 between the glue pressing wheel 11 and the paper receiving assembly 13 will increase. The tensioning frame 3 swings upward under the action of the elastic tensioner to play a tensioning role on the backing paper 91 to prevent the backing paper 91 from being fluffy; When the paper receiving speed of the paper receiving assembly 13 is higher than the glue spreading speed of the glue pressing wheel 11, the length of the backing paper 91 between the glue pressing wheel 11 and the paper receiving assembly 13 will decrease. The paper receiving action of the paper receiving assembly 13 will overcome the elastic force of the elastic tensioner and drive the tensioning frame 3 to swing downward to adapt to the reduction of the length of the backing paper 91 for tensioning. Through the above structural principle, the tensioning frame 3 and the tensioning wheel 31 cooperate with the elastic tensioning force application to achieve the purpose of matching the paper receiving speed of the paper receiving assembly 13 with the glue spreading speed of the glue pressing wheel 11.

[0034] The elastic tensioner can be implemented by various known technologies such as springs and spring plates with elastic force, and its setting can be easily obtained by those skilled in the art according to conventional technical means, so it will not be elaborated here and is not shown in the figure. Of course, on the paper receiving path, a paper receiving guide wheel set 15 can also be provided on the glue application seat 1 to optimize the guiding of the paper receiving path, which can also be easily obtained by those skilled in the art according to conventional technical means and will not be elaborated here.

[0035] Preferably, an over-tight detector 32 is installed on the glue application seat 1. When the lining paper 91 between the pressure glue wheel 11 and the paper receiving assembly 13 is short to a certain extent, the over-tight detector 32 detects the position of the tensioning frame 3 to avoid the lining paper 91 between the pressure glue wheel 11 and the paper receiving assembly 13 from being over-tightened and torn. The over-tight detector 32 is signal-connected to the paper receiving assembly 13 to control the paper receiving assembly 13 to stop when the above over-tightening occurs, so as to relieve the over-tightening situation.

[0036] A tape stopping mechanism 4 is provided on the glue application seat 1 on the incoming tape side of the tensioning wheel 31. The tape stopping mechanism 4 is used to forcibly stop the tape 9 etc. on the incoming tape side of the tensioning wheel 31 at the end of one-time glue application, and release the forced stopping effect during the next glue application. The tape stopping mechanism 4 in this embodiment includes a tape stopping cylinder installed on the glue application seat 1, and the piston end of the tape stopping cylinder is used to press the tape 9 onto the glue supply guide wheel set 14, and through this pressing action, the tape stopping function is realized. Of course, in actual setting, a tape stopping rod is swingably installed on the glue application seat 1, and the free end of the tape stopping rod is driven by a cylinder to press the tape 9 onto the glue supply guide wheel set 14, or the tape 9 etc. is directly clamped by a finger cylinder, etc., and whether the tape stopping mechanism 4 forcibly stops the tape 9 on the incoming tape side of the pressure glue wheel 11 or forcibly stops the lining paper 91 between the pressure glue wheel 11 and the tensioning wheel 31, etc., these are all equivalent transformation methods of the tape stopping mechanism 4 and should all be within the protection scope of the tape stopping mechanism 4.

[0037] As Figure 4 and Figure 5 shown, preferably, the glue application seat 1 is connected with a glue application driving mechanism 5 and a lifting driving mechanism 6. The glue application driving mechanism 5 includes a glue application transverse movement seat 51, and the glue application transverse movement seat 51 is connected with a transverse movement driver 52; the lifting driving mechanism 6 includes a lifting seat 61 installed on the glue application transverse movement seat 51, and a lifting driver 62 is arranged between the lifting seat 61 and the glue application transverse movement seat 51; the glue application seat 1 is fixedly connected with the lifting seat 61.

[0038] When applying glue, the lifting driver 62 drives the lifting seat 61 to descend, the glue pressing wheel 11 presses the tape 9 against the label 8, the transverse movement driver 52 drives the glue applying transverse movement seat 51 to move horizontally, and the glue 92 on the tape 9 can be bonded to the label 8 at the glue pressing wheel 11. Accordingly, the glue applying speed at the glue pressing wheel 11 is generated by the speed of the horizontal movement driven by the transverse movement driver 52. Among them, the transverse movement driver 52 and the lifting driver 62 can both be implemented in one of the forms such as a driving cylinder, a motor with transmission, etc., and are not limited herein. In addition, this embodiment shows the arrangement of the glue applying feed in the order of arranging the lifting mechanism on the transverse movement mechanism. Other arrangements such as arranging the transverse movement mechanism on the lifting mechanism belong to equivalent technical means transformation and should also be within the protection scope of the present utility model.

[0039] Preferably, an elastic buffer 63 is installed between the glue applying seat 1 and the glue applying transverse movement seat 51. By the elastic buffer 63, a part of the overall gravity of the glue applying seat 1 and its upper structure is balanced. On the one hand, when the lifting driver 62 drives the lifting seat 61 to descend, the glue pressing wheel 11 will not press too fast onto the label 8, avoiding damage to the structure and the glue 92 caused by too fast pressing. On the other hand, when the lifting driver 62 uses a driving cylinder, a certain hanging force can be provided for the glue applying seat 1 in the case that the driving cylinder loses the power source, avoiding the situation that the glue 92 at the glue pressing wheel 11 is randomly bonded due to the self-falling of the glue applying seat 1.

[0040] In this embodiment, when only bonding one double-sided tape on the label 8, it can be realized only by the above-mentioned combination of horizontal movement and lifting movement. When used for bonding two or more double-sided tapes on the label 8, it can be realized by a combination of multiple sets of glue applying seats 1 and horizontal and lifting movements. Of course, when used for bonding two or more double-sided tapes on the label 8, it can also be realized by adding an additional position-changing mechanism 7 at one set of glue applying seats 1. Specifically: a horizontal position-changing seat 71 is installed on the glue applying transverse movement seat 51, the moving direction of the horizontal position-changing seat 71 is arranged crosswise with the moving direction of the glue applying transverse movement seat 51, and a position-changing driver 72 is provided between the horizontal position-changing seat 71 and the glue applying transverse movement seat 51; the lifting seat 61 is installed on the horizontal position-changing seat 71, and the lifting driver 62 is provided between the lifting seat 61 and the horizontal position-changing seat 71. After bonding one double-sided tape, the glue applying seat 1 is lifted and then changed to another bonding position to bond the second double-sided tape. Of course, in this structure, the elastic buffer 63 is installed between the glue applying seat 1 and the horizontal position-changing seat 71.

[0041] Among them, the position-changing driver 72 can also be implemented in one of the forms such as a driving cylinder, a motor with transmission, etc., and is not limited herein. Of course, the order settings of horizontal movement, position change, and lifting can also be changed and are not limited herein.

[0042] In the use of this embodiment, first, through controls such as lateral movement, the rubber pressing wheel 11 is moved to directly above the starting point of the bonding position on the label 8. The lifting driver 62 drives the lifting seat 61 to descend, and the rubber pressing wheel 11 presses on the label 8. The front end of the glue body 92 located directly below the rubber pressing wheel 11 adheres to the label 8. The tape stopping mechanism 4 releases the forced stop function, and the lateral movement driver 52 and the paper receiving assembly 13 are started simultaneously. The rubber pressing wheel 11 rotates passively driven by the glue spreading lateral movement seat 51, and the passive rotation causes the extraction of the tape 9 in the glue supply assembly 12. The paper receiving assembly 13 actively winds up the remaining backing paper 91 after the glue body 92 is bonded. During this process, the tensioning function of the tensioning wheel 31 matches the glue spreading speed at the rubber pressing wheel 11 and the paper receiving speed of the paper receiving assembly 13. At the glue cutting mechanism 2, the length is measured starting from the previous glue cutting point. When the specified length is reached, the glue body 92 is cut off in advance. When this breaking point reaches the position directly below the rubber pressing wheel 11, the specified length of the glue body 92 is pasted on the label 8. The tape stopping mechanism 4 forcibly stops the tape 9, etc. The lateral movement driver 52 and the paper receiving assembly 13 stop, and the lifting driver 62 drives the lifting seat 61 to rise. Through controls such as lateral movement, the rubber pressing wheel 11 is moved to directly above the next bonding position or the starting point of the bonding position of the next label 8, and the above glue application operation is repeated.

[0043] Based on the above structural principle, in this embodiment, the tensioning wheel 31 buffers the glue spreading speed of the rubber pressing wheel 11 and the paper receiving speed of the paper receiving assembly 13. After one glue spreading is completed, the tape stopping mechanism 4 forcibly stops the tape 9, etc. on the side where the tensioning wheel 31 is driven. The floating movement at the tensioning wheel 31 stops, and it will no longer affect the output of the tape 9. Therefore, during the next glue spreading, the glue body 92 on the tape 9 is still in the state where the front end is located below the rubber pressing wheel 11. The tape stopping mechanism 4 releases the forced stop function, and the glue body 92 on the tape 9 can be bonded in the way that the front end is sequentially pasted on the label 8, without problems such as excessive bonding or tape 9 lifting. The glue application is smooth. In this way, cycling is conducive to maintaining continuous glue application operations.

[0044] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
