An automatic rubber pasting device with deviation prevention function

Abstract

This utility model discloses an automatic adhesive applicator with anti-deviation function, including an adhesive applicator body, a spare wheel device, a sweeping device, and a rebound device. The adhesive applicator body is equipped with a pressing roller and a fixing block. The two ends of the pressing roller pass through the fixing block and extend to both sides. By applying pressure perpendicular to the direction of tape movement, the tape is bonded to the substrate. The spare wheel device is symmetrically arranged on the outer sides of both ends of the pressing roller. When the pressing roller is tilted at one end due to foreign objects on the substrate surface, the spare wheel device drives a pulley to abut against the substrate, so that the pulley is collinear with the untilted end of the pressing roller and perpendicular to the direction of tape movement. The sweeping device is arranged below the spare wheel device to remove movable foreign objects in the movement path before tape application. When encountering immovable foreign objects, it can deflect and avoid them. The rebound devices are arranged on both sides above the pressing roller to quickly reset the pressing roller after it is removed from the foreign object. The spare wheel device provides support when the pressing roller tilts, preventing deviation during tape application.

Description

Technical Field

[0001] This utility model relates to the technical field of tape machine equipment, specifically to an automatic tape applicator with anti-deviation function. Background Technology

[0002] In the utility model patent application CN220702759U, published on April 2, 2024, entitled "An Automatic Tape Applying Machine for Corrugated Cardboard to Prevent Deviation," this utility model discloses an automatic tape applying machine for corrugated cardboard to prevent deviation. The key technical points of this machine are: a support frame, a feeding wheel on the upper surface of the support frame, a limiting wheel at one end of the upper surface of the support frame, a fixed frame fixedly connected to the upper surface of the support frame, a transmission belt on the inner wall of the support frame, a motor at one end of the lower surface of the support frame, a tape body on the outer side of the limiting wheel, connecting rods at both ends of the support frame, both ends of the connecting rods fixedly connected to the inner side of the support frame, limiting blocks arranged at both ends of the upper surface of the support frame, a fixing bolt at one end of each limiting block, and the bottom end of each fixing bolt movably connected to the upper surface of the support frame. The advantages are: By providing a limiting wheel and a limiting block, this utility model can limit the tape body to a certain extent when using the device, which can prevent deviation during the pasting process and improve the pasting stability of the device.

[0003] In the aforementioned patents or prior art, the pressing roller on the automatic adhesive applicator is used to apply radial pressure to the adhesive tape to achieve adhesion to the substrate. However, when there are foreign objects in the gap between the substrate and the pressing roller, one end of the pressing roller will lift up, causing the automatic adhesive applicator to deviate from its intended trajectory. Utility Model Content

[0004] The purpose of this invention is to provide an automatic adhesive applicator with anti-deviation function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic adhesive applicator with anti-deviation function, comprising: an adhesive applicator body, spare wheel devices, a sweeping device, and a rebound device; taking the direction of tape movement in the automatic adhesive applicator as the first direction, and the direction perpendicular to the first direction on the same vertical plane as the second direction, the adhesive applicator body includes a pressure roller and a fixing block, with both ends of the pressure roller passing through the fixing block and extending outwards, the pressure roller applying pressure in the second direction to the tape to make the tape adhere to the substrate; two spare wheel devices are respectively disposed on the outer sides of the fixing blocks on both sides, and the spare wheel devices are respectively connected to both ends of the pressure roller, when the pressure roller is caused by foreign matter on the surface of the substrate, one end of the pressure roller begins to tilt upwards along the second direction. At this time, the spare wheel device connected to the raised end of the pressing roller will drive the vertically set pulley to abut against the substrate. At this time, the pulley and the unraised end of the pressing roller are on the same straight line and perpendicular to the first direction. Two sweeping devices are respectively set below each spare wheel device. The sweeping devices are used to remove movable foreign objects on the tape bonding track from the tape's preset bonding path before the tape is bonded to the substrate, to prevent the tape from deviating due to movable foreign objects. When the sweeping device encounters an immovable foreign object, it will deflect and will not hinder the bonding of the tape. Two rebound devices are respectively set above the two sides of the pressing roller along the second direction. When the raised end of the pressing roller leaves the highest point of the foreign object, the rebound device quickly drives the raised end of the pressing roller to return to the initial position.

[0006] Furthermore, the spare wheel device includes: a toothed plate, a gear, a telescopic sleeve, and a pulley. The toothed plate is respectively positioned above both ends of the pressing roller along the second direction. The toothed plate is slidably connected to the fixed block. The toothed plate has only one tooth. The gear is positioned on the outside of one end of the pressing roller and meshes with the tooth on the toothed plate. The telescopic sleeve is arranged parallel to the fixed block. The telescopic inner cylinder of the telescopic sleeve has multiple continuous teeth. The teeth of the telescopic sleeve mesh with the gear. When one end of the pressing roller moves upward, it pushes the toothed plate upward and drives the gear to rotate, thereby driving the telescopic sleeve to extend. When the raised pressing roller returns to its original position, the only tooth on the toothed plate meshes with the gear, thereby driving the telescopic sleeve to retract.

[0007] Furthermore, the bottom end of the telescopic inner cylinder is fixedly connected to the pulley, which can move along the pasting direction. Thus, when one end of the pressing roller is lifted, the pulley and the other end of the pressing roller will keep the automatic adhesive applicator stable and prevent the automatic adhesive applicator from having only one contact point with the substrate, thus preventing deviation.

[0008] Furthermore, the top of the fixed block and the telescopic sleeve are fixedly connected by connecting rods respectively, and the gear is connected to the fixed block by the fixed rod, and the gear is rotatably connected to the fixed rod.

[0009] Furthermore, a first reinforcing rib is provided below the connecting rod to enhance the connection between the connecting rod and the fixing block, and a second reinforcing rib is provided below the fixing rod to enhance the connection between the fixing rod and the fixing block.

[0010] Furthermore, the fixed block has a through slot inside, and the two ends of the pressing roller are respectively connected to the toothed plate through two slots. A telescopic rod is provided inside the slot along the second direction. One end of the telescopic rod is fixedly connected to the fixed block, and the other end of the telescopic rod is fixedly connected to the push plate. The push plate is in contact with the pressing roller. A spring is provided on the outside of the telescopic rod, and the spring is respectively set between the top of the telescopic rod and the push plate.

[0011] Furthermore, a connecting block is provided below the fixed block along the second direction, and a vertical cylindrical connecting roller is provided at the bottom end of the connecting block. A sweeping roller is rotatably connected to the bottom end of the connecting roller. The sweeping roller is arranged along the longitudinal direction, and one end of the two sweeping rollers contacts each other. A torsion spring is provided between the connecting roller and the sweeping roller.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the automatic adhesive applicator with anti-deviation function is reasonable and has the following advantages:

[0013] This technical solution features spare wheels at both ends of the pressing roller. When one end of the pressing roller lifts up due to foreign objects on the substrate surface, the spare wheels drive a pulley to apply radial pressure to the substrate at the instant the roller lifts up. The direction between the other end of the pressing roller and the pulley is perpendicular to the adhesive tape bonding direction. When one end of the pressing roller lifts up due to foreign objects, the pulley on the outside of the lifted end of the pressing roller and the unlifted end of the pressing roller continue to maintain the overall balance of the automatic adhesive applicator. This prevents the automatic adhesive applicator from lifting up at one end due to foreign objects in the tape path, which would result in the automatic adhesive applicator having only one contact point with the substrate and thus deviating from its intended path. This ensures that the adhesive application trajectory of the automatic adhesive applicator always conforms to the preset trajectory.

[0014] This technical solution involves installing sweeping devices on both sides below the spare wheel device. Before the tape is bonded to the substrate by the radial pressure of the pressing roller, the sweeping devices remove movable foreign objects from the substrate surface from the preset adhesive application path. This prevents one end of the pressing roller from being lifted by foreign objects, causing the automatic adhesive applicator to deviate. When encountering immovable foreign objects, the sweeping devices can deflect to avoid them, without obstructing the relative movement between the automatic adhesive applicator and the substrate. When the sweeping devices leave the immovable foreign objects, they can deflect back to their original position and continue sweeping the adhesive application path to remove debris.

[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] Please see Figure 1-8 The present invention provides a technical solution as follows:

[0026] Example 1:

[0027] An automatic adhesive applicator with anti-deviation function is provided, comprising: an adhesive applicator body 1, a spare wheel device 3, a sweeping device 4, and a rebound device 5;

[0028] Taking the direction of tape movement in the automatic tape applicator as the first direction, and the direction perpendicular to the first direction on the same vertical plane as the second direction, the tape applicator body 1 includes a pressing roller 11 and a fixing block 12. The two ends of the pressing roller 11 pass through the fixing block 12 and extend outward. The pressing roller 11 applies pressure in the second direction to the tape, causing the tape to adhere to the substrate.

[0029] Two spare wheel devices 3 are respectively set on the outside of the two fixed blocks 12. The spare wheel devices 3 are respectively connected to both ends of the pressing roller 11. When the pressing roller 11 is caused to tilt upward along the second direction due to foreign objects on the surface of the substrate, the spare wheel device 3 connected to the tilted end of the pressing roller 11 will drive the vertically set pulley 33 to abut against the substrate. At this time, the pulley 33 and the non-tilted end of the pressing roller 11 are on the same straight line and perpendicular to the first direction.

[0030] Two sweeping devices 4 are respectively set below each spare wheel device 3. The sweeping device 4 is used to remove movable foreign objects on the tape bonding track from the tape's preset bonding path before the tape is bonded to the substrate, so as to prevent the tape from deviating due to movable foreign objects. When the sweeping device 4 encounters an immovable foreign object, it will deflect and will not hinder the bonding of the tape.

[0031] Two spring-loaded devices 5 are respectively positioned above the two sides of the pressing roller 11 along the second direction. When the raised end of the pressing roller 11 leaves the highest point of the foreign object, the spring-loaded device 5 quickly drives the raised end of the pressing roller 11 to return to the initial position.

[0032] The spare wheel device 3 includes: a toothed plate 31, a gear 32, a telescopic sleeve 34, and a pulley 33. The toothed plate 31 is respectively arranged above both ends of the pressing roller 11 along the second direction. The toothed plate 31 is slidably connected to the fixed block 12. The toothed plate 31 has only one tooth. The gear 32 is arranged on the outside of one end of the pressing roller 11 and meshes with the tooth on the toothed plate 31. The telescopic sleeve 34 is arranged parallel to the fixed block 12. The telescopic inner cylinder 341 of the telescopic sleeve 34 has multiple continuous teeth. The teeth of the telescopic sleeve 34 mesh with the gear 32. When one end of the pressing roller 11 moves upward, it pushes the toothed plate 31 to move upward and drives the gear 32 to rotate, thereby driving the telescopic sleeve 34 to extend. When the raised pressing roller 11 returns to its original position, the only tooth on the toothed plate 31 meshes with the gear 32, thereby driving the telescopic sleeve 34 to retract.

[0033] The bottom end of the telescopic inner cylinder 341 is fixedly connected to the pulley 33. The pulley 33 can move along the pasting direction, so that when one end of the pressing roller 11 is raised, the pulley 33 and the other end of the pressing roller 11 will keep the automatic adhesive applicator stable and prevent the automatic adhesive applicator from running off-center due to having only one contact point with the substrate.

[0034] The top ends of the fixed block 12 and the telescopic sleeve 34 are fixedly connected by the connecting rod 35 respectively. The gear 32 is connected to the fixed block 12 by the fixed rod 36, and the gear 32 is rotatably connected to the fixed rod 36.

[0035] A first reinforcing rib 37 is provided below the connecting rod 35 to enhance the connection between the connecting rod 35 and the fixing block 12. A second reinforcing rib 38 is provided below the fixing rod 36 to enhance the connection between the fixing rod 36 and the fixing block 12.

[0036] The fixed block 12 has a through slot inside. The two ends of the pressing roller 11 pass through the two slots and are fixedly connected to the toothed plate 31. The slot is provided with a telescopic rod 52 along the second direction. One end of the telescopic rod 52 is fixedly connected to the fixed block 12, and the other end of the telescopic rod 52 is fixedly connected to the push plate 53. The push plate 53 is in contact with the pressing roller 11. A spring 51 is provided on the outside of the telescopic rod 52. The spring 51 is respectively located between the top of the telescopic rod 52 and the push plate 53.

[0037] Below the fixed block 12, there is a connecting block 41 along the second direction. At the bottom of the connecting block 41, there is a vertical cylindrical connecting roller 42. At the bottom of the connecting roller 42, there is a sweeping roller 44 rotatably connected. The sweeping roller 44 is arranged along the longitudinal direction. One end of the two sweeping rollers 44 is in contact. A torsion spring 43 is provided between the connecting roller 42 and the sweeping roller 44.

[0038] Working principle: When in use, the tape is placed in the automatic adhesive applicator. The pressure roller 11 provides radial pressure to the tape, causing the tape to adhere to the substrate surface. The automatic adhesive applicator moves relative to the substrate, causing the tape to adhere to the substrate surface, thus achieving automatic adhesive applicator.

[0039] When foreign objects appear on the substrate surface, a sweeping device 4 is provided below the automatic adhesive applicator. Before the tape is bonded to the substrate, the sweeping roller 44 on the sweeping device 4 will first contact the foreign objects on the substrate surface. If the foreign objects are movable, the sweeping roller 44 will move the foreign objects out of the preset tape bonding path. When encountering immovable foreign objects, the sweeping roller 44 is rotatably connected to the connecting roller 42, so that the sweeping roller 44 rotates horizontally, so that the automatic adhesive applicator and the substrate maintain relative movement. A torsion spring 43 is connected between the sweeping roller 44 and the connecting roller 42. When the rotating sweeping roller 44 encounters an immovable foreign object, it will rotate back to its original position under the pull of the torsion spring 43.

[0040] When the automatic adhesive applicator encounters an immovable foreign object, one end of the pressing roller 11 will tilt upwards due to the presence of the foreign object. The instant one end of the pressing roller 11 tilts upwards, it drives the toothed plates 31 located above both ends of the pressing roller 11 to move upwards. The toothed plates 31 mesh with gears 32. The telescopic inner cylinder 341 of the telescopic sleeve 34, which is parallel to the gears 32, has teeth. The telescopic inner cylinder 341 meshes with the gears 32. A pulley 33 is connected to the bottom end of the telescopic inner cylinder 341. When the pressing roller 11 tilts upwards, the toothed plates 31... The gear 32 drives the pulley 33 to move down and maintain the balance of the automatic adhesive applicator with the non-curved end of the pressing roller 11, so as to avoid the automatic adhesive applicator from deviating due to having only one contact point with the substrate. The toothed plate 31 has only one tooth to remove the influence of the height of the foreign object on the descent height of the pulley 33. The pulley 33 is radially arranged so that the pulley 33 and the non-curved end of the pressing roller 11 continue to move along the preset tape bonding path. When the pressing roller 11 leaves the foreign object, the springback device 5 presses the curled end of the pressing roller 11 back to its original position in time.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
