Description

Technical Field

[0001] The present invention relates to the technical field of product detection, and in particular to a back adhesive detection device. Background Art

[0002] Adhesive tape is one of the most common products used in daily life, often used to bond two components. During production, the finished adhesive is placed on a substrate, covered with a barrier layer to prevent dust from adhering to the adhesive surface and reducing adhesion, and then rolled up for storage. To ensure the quality of adhesive-backed products before leaving the factory, the rolls are inspected using industrial cameras. Once qualified, they are cut into different lengths and specifications for sale to meet the needs of different customers.

[0003] When inspecting the adhesive backing, a unwinding roller and a rewinding roller are usually set up. The uninspected adhesive backing roll is placed on the unwinding roller and released, and is rewound by the rewinding roller after inspection. The industrial camera is located between the unwinding roller and the rewinding roller. During the inspection process, the adhesive backing needs to be in a flat and taut state, otherwise the industrial camera will seriously affect the inspection results when shooting.

[0004] For example, the existing patent with application number 202122716235.9, publication (announcement) number CN218412287U, and name "A kind of testing equipment for adhesive production" discloses that two pressing rollers press the adhesive through two rotating bars. At the same time, the force generated by the pressing mechanism acts on the two rotating bars through two fixed blocks, causing the two rotating bars to rotate a certain angle. The two rotating bars respectively press and smooth the passing adhesive through two pressing rollers, so that the adhesive remains flat during transportation and inspection on the inspection table. The visual inspection instrument inspects the adhesive pressed and smoothed by the two pressing rollers to determine whether the adhesive is qualified.

[0005] At the same time, during the detection process, since the diameter of the backing adhesive roll on the unwinding roller will become smaller and smaller, and the diameter of the backing adhesive roll on the winding roller will become larger and larger, in order to ensure the tension of the backing adhesive, the existing technology will also make more complex algorithm programs for the unwinding speed of the unwinding roller and the winding speed of the winding roller, so that the unwinding roller and the winding roller can be precisely matched. However, the complex algorithm design will greatly increase the manufacturing difficulty of the equipment and the cost will increase sharply.

[0006] Therefore, in order to ensure the accuracy of the back glue detection, it is crucial to keep the back glue in a tensioned state. How to keep the back glue in a tensioned state during the detection process without having to design a complex algorithm for the unwinding speed of the unwinding roller and the winding speed of the winding roller to reduce the manufacturing difficulty and cost of the equipment is urgently needed to be improved. Moreover, after the back glue roll is completely wound onto the winding roller, it is necessary to use a special cutting tool or cutting equipment to cut the tested back glue roll into different lengths to meet the purchasing needs of different customers. However, the separate cutting process will undoubtedly reduce work efficiency. Therefore, how to keep the back glue in a tensioned state without having to design a complex algorithm for the unwinding speed of the unwinding roller and the winding speed of the winding roller to reduce the manufacturing difficulty and cost of the equipment, and how to complete the cutting of the back glue roll into different lengths during the detection process to save the separate cutting process at a later time is a technical problem that needs to be solved. Summary of the Invention

[0007] The purpose of the present invention is to provide a back glue detection device to solve the above-mentioned deficiencies in the prior art.

[0008] To achieve the above-mentioned object, the present invention provides the following technical solution: a backing adhesive detection device, comprising a support body, a reel and a reel rotatably mounted on the support body, the reel and the reel rotating at different speeds, a plurality of directional rollers rotatably mounted on the support body, and a tensioning member slidably mounted on the support body; The tensioning member includes a lifting shaft slidably connected to the support body, and a pressure roller is rotatably provided on the lifting shaft, and a circular plate is elastically rotatably provided; A cutter assembly is elastically rotatably provided on the circular plate; A fixed rod is fixedly installed on the support body and is in contact with the circular plate. The adhesive backing passes through multiple directional rollers in sequence and then passes through the bottom of the pressure roller and is wound up by the winding roller. The adhesive backing is driven into a tensioned state based on the weight of the tensioning member. In the process of the winding roller winding up the adhesive backing, the adhesive backing pulls the tensioning member to slide continuously toward the fixed rod. The fixed rod pushes the circular plate to rotate elastically so that the circular plate drives the tool assembly to abut against the blocking rod installed on the support body so that the tool assembly can elastically rotate and cut the adhesive backing.

[0009] The above-mentioned adhesive backing detection equipment has a first support plate fixedly installed on the support body, a first slide groove is provided on the support body, a second slide groove corresponding to the first slide groove is provided on the first support plate, and a slider is detachably installed at both ends of the lifting shaft, one slider is slidably set in the first slide groove, and the other slider is slidably set in the second slide groove, and the slider and the lifting shaft cannot rotate relative to each other.

[0010] In the above-mentioned adhesive detection device, both ends of the lifting shaft are provided with inner grooves, the slider is provided with a socket for the end of the lifting shaft to slide into, and the inside of the socket is fixed with a lock key that is slidably inserted into the inner groove.

[0011] The above-mentioned adhesive backing detection equipment has two circular plates, the pressure roller is located between the two circular plates and does not contact the two circular plates, a notch is opened on the circular plate to form an inclined surface on the circular plate, and the number of the fixing rods is two and they slide and abut against the inclined surfaces on the two circular plates in a one-to-one correspondence.

[0012] In the above-mentioned adhesive detection device, a first elastic member is connected between the circular plate and the lifting shaft. The first elastic member is a torsion spring. The torsion spring is fixedly connected to the lifting shaft, and one end of the torsion spring abuts against the circular plate.

[0013] The above-mentioned adhesive back detection equipment, a first elastic member is connected between the circular plate and the lifting shaft, the first elastic member includes a first push block fixedly mounted on the circular plate, a first limiting plate fixedly mounted on the lifting shaft and abutting against the first push block, a first circular ring fixedly mounted on the first limiting plate and coaxial with the lifting shaft, and a first arc-shaped compression spring sleeved on the first circular ring, the first circular ring is slidably plugged into the first push block, one end of the first arc-shaped compression spring abuts against the first limiting plate, and the other end abuts against the first push block, and based on the elastic force of the first arc-shaped compression spring, the first push block abuts against the first limiting plate in the initial state.

[0014] The above-mentioned adhesive back detection equipment, the tool assembly includes a seesaw, the seesaw is rotatably connected to the circular plate through an axis, the end of the seesaw is fixedly installed with a cutter head, and the upper limit block and the lower limit block are fixedly installed on the circular plate, the end of the seesaw away from the cutter head passes between the upper limit block and the lower limit block and abuts against the barrier rod, a compression spring is connected between the lower limit block and the seesaw, and the elastic force of the compression spring drives the seesaw to abut against the upper limit block.

[0015] The above-mentioned adhesive back detection equipment has a support plate detachably installed in the inner groove at both ends of the lifting shaft, a rotating shaft is rotatably installed between the two support plates, a tape ring is rotatably sleeved on the rotating shaft, a swing plate is elastically rotatably provided on the rotating shaft through a second elastic member, an extrusion roller that adheres to the single-sided tape on the tape ring is rotatably provided on the swing plate, the rotating shaft is linked to the circular plate so that the rotating shaft is driven to rotate when the circular plate rotates, and the rotational force of the rotating shaft drives the swing plate to drive the extrusion roller to squeeze the single-sided tape and adhere it to the adhesive backing wound on the winding roller.

[0016] In the above-mentioned adhesive detection device, a gear is fixedly sleeved on the rotating shaft, and the outer circumference of one of the circular plates is provided with meshing teeth that mesh with the gear. When the circular plate rotates, the meshing teeth drive the gear and the rotating shaft to rotate.

[0017] In the above-mentioned adhesive detection equipment, the tool assembly cuts the adhesive and the tensioning member drives the squeezing roller to fall synchronously. During the falling process, the squeezing roller elastically squeezes the adhesive rolled on the winding roller to prevent the adhesive rolled on the winding roller from loosening.

[0018] Beneficial effects: 1. In the above technical solution, the present invention provides a back glue detection device. The present invention sets a tensioning member on the support body in a sliding manner, and uses the winding roller to gradually increase the diameter of the back glue roll on the winding roller and gradually reduce the diameter of the undetected back glue roll during the process of winding the back glue, so that the back glue will continuously push the tensioning member to slide upward during winding, so that the tensioning member always squeezes the back glue downward, so that the back glue is always in a tensioned state during detection, so as to ensure the accuracy of back glue detection, without the need for complex algorithm design for the rotation speed of the unwinding roller and the winding roller, thereby reducing the manufacturing difficulty and cost of the device; and by setting a tool assembly on the circular plate of the tensioning member and fixing a fixing rod that abuts and cooperates with the circular plate on the support body, In the process of the tensioning member moving up, the fixed rod can push the circular plate to rotate, so that when the tensioning member moves up to a specific height, the circular plate drives the cutter assembly to abut against the stop rod, so that the cutter assembly automatically cuts the adhesive. More importantly, the present invention cleverly utilizes the continuous reduction in the diameter of the undetected adhesive roll, so that the length of the adhesive roll wound on the winding roller is different each time the adhesive is cut and is in a successively decreasing form, so that when the adhesive on the undetected adhesive roll passes all the inspections, the adhesive will be automatically cut into multiple parts of different length specifications and wound up to meet the purchasing needs of different customers, cleverly saving the process of cutting the undetected adhesive roll separately in the later stage, thereby improving work efficiency and effectively solving the shortcomings of the existing technology. 2. The present invention provides a rotating shaft rotatably connected to the lifting shaft, a tape loop is rotatably sleeved on the rotating shaft, and a swing plate is elastically rotated on the rotating shaft. A squeezing roller bonded to the single-sided tape on the tape loop is rotatably provided on the swing plate, so that when the circular plate rotates, the squeezing roller can squeeze the adhesive roll wound on the winding roller, so that the single-sided tape adheres to the adhesive roll wound on the winding roller. Then the circular plate drives the cutter assembly to cut the adhesive, and as the winding roller continues to rotate, the single-sided tape adheres the end of the adhesive roll wound on the winding roller to the adhesive roll, thus realizing the function of automatically "sealing" the adhesive roll wound on the winding roller, eliminating the operation of bonding the end of the adhesive roll on the winding roller to the adhesive roll at a later time. 3. Furthermore, after the cutter assembly cuts the adhesive backing, the tensioning member drives the squeezing roller to fall synchronously. During the squeezing roller's fall, it elastically squeezes the adhesive backing rolled on the take-up roller to prevent the adhesive backing rolled on the take-up roller from loosening. Specifically, after the cutter assembly cuts the adhesive backing, the tensioning member falls from a specific height to the lowest position, and the squeezing roller always elastically squeezes the adhesive backing rolled on the take-up roller. Under the elastic squeezing force of the squeezing roller, it not only serves to more firmly adhere the single-sided tape to the adhesive backing rolled on the take-up roller, but also squeezes the adhesive backing rolled on the take-up roller to prevent the end of the adhesive backing rolled from loosening before being adhered by the single-sided tape. As a result, the adhesive backing rolled on the take-up roller is "sealed" by the single-sided tape in a wound state, thereby ensuring the quality of the adhesive backing rolled. It can be seen that the design of the squeezing roller has achieved unexpected technical effects. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0023] First embodiment: like Figure 1-13As shown, an embodiment of the present invention provides an adhesive backing detection device, comprising a support body 1, a reel 3 and a reel 7 rotatably mounted on the support body 1, wherein the reel 3 and the reel 7 rotate at different speeds, a plurality of directional rollers are rotatably provided on the support body 1, and a tensioning member is slidably provided on the support body 1; The tensioning member includes a lifting shaft 18 slidably connected to the support body 1, on which a pressure roller 17 is rotatably provided and a circular plate 13 is elastically rotatably provided; A tool assembly is elastically rotatably provided on the circular plate 13; A fixed rod 12 is fixedly installed on the support body 1 and is in contact with the circular plate 13. The adhesive 2 passes through multiple directional rollers in sequence and then passes through the bottom of the pressure roller 17 and is wound up by the winding roller 7. The adhesive is driven into a tensioned state based on the weight of the tensioning member. In the process of the winding roller 7 winding up the adhesive 2, the adhesive 2 is driven to pull the tensioning member to slide continuously toward the fixed rod 12. The fixed rod 12 pushes the circular plate 13 to rotate elastically so that the circular plate 13 drives the tool assembly to abut against the blocking rod 8 installed on the support body 1 so that the tool assembly can cut the adhesive 2 by elastic rotation.

[0024] The adhesive inspection device provided in this embodiment is used to inspect adhesive and, during the inspection process, to cut and stably rewind adhesive of varying lengths. The terms regarding direction and position in this embodiment are relative to the accompanying drawings. Specifically, a first washer 301 is coaxially mounted on the unwinding roller 3, with an uninspected adhesive roll 4 wound around the first washer 301. A second washer 701 is coaxially mounted on the rewinding roller 7. The adhesive 2 on the uninspected adhesive roll 4 is pulled out and then wound around the second washer 701. In other words, the adhesive rewound by the rewinding roller 7 is wound around the second washer 701. The unwinding roller 3 and the rewinding roller 7 are either inflatable rollers or rollers with elastic extrusion members, such as rubber or metal springs, fixedly mounted on their surfaces. As long as the first washer 301 can be coaxially mounted on the unwinding roller 3 and the second washer 701 can be coaxially mounted on the rewinding roller 7 and removed from the rewinding roller 7, any suitable device is sufficient. A first motor and a second motor (not shown in the figure) are fixedly mounted on the support body 1. The power output end of the first motor is coaxially fixedly connected or keyed to the unwinding roller 3. The power output end of the second motor is coaxially fixedly connected or keyed to the winding roller 7. The first motor and the second motor are reduction motors or servo motors. The rotation speeds of the unwinding roller 3 and the winding roller 7 are different. The rotation speed of the unwinding roller 3 is lower than the rotation speed of the winding roller 7. The multiple difference between the rotation speeds of the unwinding roller 3 and the winding roller 7 matches the multiple difference between the maximum outer circumference of the undetected back adhesive roll 4 and the outer circumference of the second gasket 701. That is, when the maximum outer circumference of the undetected back adhesive roll 4 and the second When the multiple difference between the outer circumferences of the washers 701 is five times, the speed difference between the reel roller 7 and the unreel roller 3 is also five times. This ensures that the adhesive 2, if already in a tensioned state upon installation before testing, remains in a tensioned state throughout the testing process. This is because the diameter of the adhesive being reeled by the reel roller 7 increases as it reels, while the diameter of the untested adhesive roll 4 decreases. Therefore, while the speeds of the unreel roller 3 and reel roller 7 remain constant, the adhesive 2 will continue to move toward a tensioned state as the reel roller 7 continues to reel. As long as the adhesive 2 is in a tensioned state upon installation, it will remain in a tensioned state throughout the testing process. Furthermore, the diameter of the first washer 301 is greater than the diameter of the second washer 701 to ensure the adhesive length when the reel roller 7 reels the final roll. The difference between the diameter of the first gasket 301 and the diameter of the second gasket 701 is determined by the minimum length specification of the adhesive tape that needs to be cut. When the difference between the diameter of the first gasket 301 and the diameter of the second gasket 701 is smaller, the length of the adhesive tape rolled up when the winding roller 7 winds up to the last roll of adhesive tape is smaller.

[0025] In this embodiment, the number of directional rollers is at least three, including two first rollers 5 and one second roller 6. The two first rollers 5 are of the same height so that the adhesive 2 located between the two first rollers 5 is in a horizontal state. The second roller 6 is higher than the first roller 5 and the tensioning member. The two first rollers 5 and the second roller 6 are arranged in sequence toward the tensioning member. The adhesive 2 on the undetected adhesive roll 4 is pressed and passed through the bottom of the two first rollers 5, then passed around the top of the second roller 6, and then passed around the bottom of the tensioning member before being wound around the second gasket 701 and reeled up. An industrial camera 10 and a lighting lamp 11 arranged vertically are also installed on the support body 1. The industrial camera 10 and the lighting lamp 11 are located between the two first rollers 5. The industrial camera 10 is used to photograph and detect the adhesive 2. The technology for detecting the adhesive 2 is existing technology and will not be repeated in this embodiment. Any detection method in the existing technology can be used for detection. A support platform 101 is also fixedly installed on the support body 1. The support platform 101 is located at the bottom of the adhesive 2 between the two first rollers 5 and is used to support the adhesive 2. The adhesive 2 is squeezed by the first rollers 5 and the support platform 101. When the adhesive 2 moves, it drives the two first rollers 5 to rotate.

[0026] The tensioning member is used to keep the adhesive 2 in a tensioned state during the inspection process, and cooperates with the two first rollers 5 to keep the adhesive 2 below the industrial camera 10 in a tensioned and flat state to ensure the accuracy of the inspection. The tensioning member is slidably connected to the support body 1 in the vertical direction. As the diameter of the adhesive roll being wound by the winding roller 7 gradually increases during the process of winding the adhesive 2, and the diameter of the uninspected adhesive roll 4 gradually decreases, the adhesive 2 is continuously tightened as the winding progresses, causing the length of the adhesive 2 between the unwinding roller 3 and the winding roller 7 to continuously decrease, thereby causing the adhesive 2 to continuously push the tensioning member upward to slide. The fixed rod 12 is fixedly connected to the support body 1 through the second support plate 104, and the fixed rod 12 is located above the tensioning member. The tensioning member includes a lifting shaft 18 that is slidably connected to the support body 1 in the vertical direction. The lifting shaft 18 can only slide up and down in the vertical direction and cannot rotate. The inner rings of the pressure roller 17 and the circular plate 13 are both rotated to match a bearing 26. The bearing 26 is rotatably sleeved on the lifting shaft 18. There is no contact between the pressure roller 17 and the circular plate 13. When the pressure roller 17 rotates, it will not drive the circular plate 13 to rotate. When the circular plate 13 rotates, it will not drive the pressure roller 17 to rotate. The setting of the bearing 26 makes it possible for the pressure roller 17 and the circular plate 13 to rotate smoothly on the lifting shaft 18, wherein the circular plate 13 and the lifting shaft A first elastic member is also provided between the rollers 18. Based on the provision of the first elastic member, the circular plate 13 and the lifting shaft 18 are elastically rotatable, so that the circular plate 13 will not rotate without external force. The circular plate 13 abuts and cooperates with the fixed rod 12. When the circular plate 13 does not abut against the fixed rod 12, the circular plate 13 will not rotate. As the adhesive 2 is continuously wound, the adhesive 2 drives the entire tensioning member to move upward, thereby causing the circular plate 13 to move toward the fixed rod 12 so that the circular plate 13 abuts against the fixed rod 12. Then, the fixed rod 12 pushes the circular plate 13 to rotate elastically. The adhesive 2 abuts and passes through the bottom of the pressure roller 17. Under the action of the gravity of the tensioning member, the outer circumference of the pressure roller 17 presses down the adhesive 2, so that the adhesive 2 is in a tensioned state. When the adhesive 2 is wound under the rotational force of the winding roller 7, the adhesive 2 is driven to move. The adhesive 2 then drives the pressure roller 17, the second roller 6, and the two first rollers 5 to rotate. The fixing rod 12 is located directly above the circular plate 13 and is used to abut against the circular plate 13. In the initial state, the fixing rod 12 and the circular plate 13 are not in abutment. The distance between the fixing rod 12 and the circular plate 13 is set according to the length of the adhesive backing to be rolled up. The longer the length of the adhesive backing to be rolled up, the larger the distance between the fixing rod 12 and the circular plate 13 is set.

[0027] The cutter assembly is elastically connected to the circular plate 13 for rotation, and the adhesive 2 passes between the pressure roller 17 and the cutter assembly. Before the circular plate 13 abuts the fixed rod 12, the cutter assembly only moves in the vertical direction following the circular plate 13. When the fixed rod 12 pushes the circular plate 13 to rotate elastically, the circular plate 13 drives the cutter assembly to rotate following the circular plate 13, so that the cutter assembly abuts against the stop rod 8. The stop rod 8 is fixedly connected to the support body 1, and the cutter assembly is elastically rotated under the blocking action of the stop rod 8. The cutter head 1402 is fixedly installed on one end of the cutter assembly close to the adhesive 2, and the cutter head 1402 cooperates with the pressure roller 17. When the cutter assembly is elastically rotated under the driving force of the rotation of the circular plate 13 and the blocking action of the stop rod 8, the cutter head 1402 is driven to rotate toward the pressure roller 17, thereby cutting the adhesive 2 between the pressure roller 17 and the cutter head 1402, and smoothly cutting off the adhesive 2 under the pulling action of the winding force of the winding roller 7. It can be seen that every time the tensioning member moves up to a specific height (the specific height refers to the height to which the tensioning member moves up when the tool assembly abuts against the blocking rod 8 and drives the tool head 1402 to squeeze and cut the adhesive 2), the tool assembly can cut the adhesive 2 once.

[0028] Its working principle is as follows: first, the tensioning member is at the bottom, the first washer 301 wound with the undetected adhesive roll 4 is pressed and sleeved on the unwinding roller 3, and the second washer 701 is pressed and sleeved on the winding roller 7, and then one end of the adhesive 2 on the undetected adhesive roll 4 is pulled out and made to pass through the bottom of the two first rotating rollers 5, the top of the second rotating roller 6 and the bottom of the pressure roller 17 in sequence, and then wound on the second washer 701, and the adhesive 2 between the unwinding roller 3 and the winding roller 7 is in a tensioned state, and then the first motor and the second motor are started at the same time. The motor rotates the unwinding roller 3 and the winding roller 7 simultaneously. The rotation of the unwinding roller 3 causes the undetected adhesive roll 4 to continuously release the adhesive 2, and the rotation of the winding roller 7 causes the adhesive 2 to be continuously wound. Based on the multiple difference between the rotation speeds of the unwinding roller 3 and the winding roller 7 and the multiple difference between the maximum outer circumference of the undetected adhesive roll 4 and the outer circumference of the second gasket 701, as the adhesive 2 is continuously wound, the diameter of the undetected adhesive roll 4 is continuously reduced, while the diameter of the adhesive roll wound on the winding roller 7 is continuously increased, thereby When the winding roller 7 rotates one circle, the length of the rolled adhesive 2 becomes longer and longer, and when the unwinding roller 3 rotates one circle, the length of the released adhesive 2 becomes shorter and shorter. Then, as the unwinding work of the adhesive 2 progresses, the length of the adhesive 2 between the unwinding roller 3 and the winding roller 7 becomes shorter and shorter, so that the adhesive 2 continuously pushes the pressure roller 17 upward, and the pressure roller 17 drives the entire tensioning member to slide upward. During the upward movement of the tensioning member, the circular plate 13 continuously moves toward the fixed rod 12. When the circular plate 13 abuts against the fixed rod 12, as the tensioning member advances One step of upward movement causes the fixed rod 12 to push the circular plate 13 to rotate elastically, and the circular plate 13 drives the tool assembly to rotate with the circular plate 13 so that the tool assembly abuts against the blocking rod 8. Then the blocking rod 8 pushes the tool assembly to rotate elastically so that the cutter head 1402 moves toward the pressure roller 17, so that the cutter head 1402 cuts the adhesive backing 2 to complete the first inspection and winding of the adhesive backing 2. After the adhesive backing 2 is cut, the tensioning part automatically moves down under the action of gravity, and then the first motor and the second motor stop running. They can stop running separately or at the same time. After that, the second gasket 701 wrapped with the adhesive roll is removed from the winding roller 7, and the tensioning member automatically returns to its initial state (referring to the initial state when the adhesive 2 is not wound), and a new second gasket 701 is replaced on the winding roller 7. Then, the end of the adhesive 2 is passed around the bottom of the pressure roller 17 again and wound around the second gasket 701 again, and the adhesive 2 between the unwinding roller 3 and the winding roller 7 is kept tensioned. Then, the first motor and the second motor are started again at the same time to perform a second inspection and winding of the adhesive 2. As the winding roller 7 winds up the adhesive 2 again, the adhesive 2 drives the circular plate 13 to abut against the fixed rod 12 again until the tool assembly cuts the adhesive 2 again.Since the diameter of the undetected adhesive roll 4 during the second detection and winding of the adhesive 2 is smaller than that during the first detection and winding of the adhesive 2, the length of the adhesive 2 released when the unwinding roller 3 rotates one circle becomes smaller, so that when the adhesive 2 drives the tensioning member to move up to the height at which the tool assembly cuts the adhesive 2, the length of the adhesive roll wound on the winding roller 7 is smaller than the first time. Similarly, the length of the adhesive roll wound on the winding roller 7 is reduced each time the adhesive 2 is cut, so that the adhesive 2 on the undetected adhesive roll 4 will be cut into multiple parts with different length specifications after all the detections.

[0029] Thus, it can be seen that the present invention sets a tensioning member slidingly on the support body 1, and uses the winding roller 7 to gradually increase the diameter of the back adhesive roll on the winding roller 7 and gradually reduce the diameter of the undetected back adhesive roll 4 during the process of winding the back adhesive 2, so that the back adhesive 2 will continuously push the tensioning member to slide upward when winding, so that the tensioning member always squeezes the back adhesive 2 downward, so that the back adhesive 2 is always in a tensioned state during detection, so as to ensure the accuracy of the detection of the back adhesive 2, and there is no need to design a complex algorithm for the rotation speed of the unwinding roller 3 and the winding roller 7, thereby reducing the manufacturing difficulty and cost of the equipment; and by arranging a tool assembly on the circular plate 13 of the tensioning member, and fixing the fixed rod 12 that abuts against the circular plate 13 on the support body 1, so that the back adhesive 2 on the tensioning member can be tightened. During the movement, the fixed rod 12 can push the circular plate 13 to rotate, so that when the tensioning member moves up to a specific height, the circular plate 13 drives the tool assembly to abut against the blocking rod 8 so that the tool assembly can automatically cut the adhesive 2. More importantly, the present invention cleverly utilizes the continuous reduction in the diameter of the undetected adhesive roll 4, so that the length of the adhesive roll wound on the winding roller 7 is different each time the adhesive 2 is cut and is in a successively decreasing form, so that the adhesive 2 on the undetected adhesive roll 4 will be cut into multiple parts with different length specifications after all the inspections to meet the purchasing needs of different customers, cleverly saving the process of cutting the undetected adhesive roll 4 separately in the later stage, thereby improving work efficiency and effectively solving the shortcomings of the existing technology.

[0030] In this embodiment, a first support plate 103 is fixedly mounted on the support body 1, a first slide groove 102 is provided on the support body 1, and a second slide groove (not shown in the figure) corresponding to the first slide groove 102 is provided on the first support plate 103. A slider 16 is detachably mounted on both ends of the lifting shaft 18, wherein one slider 16 is slidably set in the first slide groove 102 and the other slider 16 is slidably set in the second slide groove, and the slider 16 and the lifting shaft 18 cannot rotate relative to each other. Specifically, the first slide groove 102 and the second slide groove are both in an inverted "L" shape, and the first slide groove 102 and the second slide groove have the same height. One end of the first slide groove 102 passes through the side of the support body 1, and one end of the second slide groove passes through one side of the first support plate 103 to facilitate the removal and installation of the two sliders 16. The slider 16 is a cube, based on the fact that one slider 16 is slidably set in the first slide groove 102 and the other slider 16 is slidably set in the second slide groove, so that the two sliders 16 cannot rotate and can only slide along the tracks of the first slide groove 102 and the second slide groove, and the lifting shaft 18 and the two sliders 16 cannot rotate relative to each other, so that the lifting shaft 18 cannot rotate and can only slide along the tracks of the first slide groove 102 and the second slide groove, thereby making the entire tensioning member can only slide along the tracks of the first slide groove 102 and the second slide groove and cannot rotate. In the initial state, the bottom of the slider 16 in the first chute 102 abuts against the bottom of the first chute 102 , and the slider 16 in the second chute abuts against the bottom of the second chute, so that the tensioning member is at the bottom.

[0031] Furthermore, both ends of the lifting shaft 18 are provided with inner grooves 1805, and the slider 16 is provided with a socket 1601 for the end of the lifting shaft 18 to slide into. The diameter of the lifting shaft 18 matches the diameter of the socket 1601, and the interior of the socket 1601 is fixed with a lock key 1602 that is slidably connected to the inner groove 1805. Based on the sliding connection between the inner groove 1805 and the lock key 1602, the lifting shaft 18 and the slider 16 cannot rotate relative to each other.

[0032] In this embodiment, there are two circular plates 13, and a pressure roller 17 is positioned between the two circular plates 13 and does not contact the two circular plates 13. A notch is provided on the circular plates 13 to form an inclined surface 1301 thereon. There are two fixed rods 12, which slide and abut against the inclined surfaces 1301 on the two circular plates 13. Specifically, a ball head 1201 is integrally formed at the bottom of the fixed rod 12. The ball head 1201 slides and abuts against the inclined surface 1301, and the abutment between the ball head 1201 and the inclined surface 1301 achieves abutment between the circular plates 13. When the ball head 1201 abuts the inclined surface 1301, as the circular plates 13 move further upward, the fixed rod 12 pushes the circular plates 13 to rotate elastically. Furthermore, by providing two circular plates 13 and positioning the pressure roller 17 between the two circular plates 13, the stability of the tensioner during operation can be effectively improved.

[0033] Among them, a first elastic member is connected between the circular plate 13 and the lifting shaft 18. The first elastic member is a torsion spring (not shown in the figure). The torsion spring is fixedly connected to the lifting shaft 18. One end of the torsion spring abuts against the circular plate 13. When the circular plate 13 rotates, it drives the torsion spring to generate torque, so that the circular plate 13 can achieve elastic rotation.

[0034] In another embodiment, a first elastic member is connected between the circular plate 13 and the lifting shaft 18, and the first elastic member includes a first push block 1302 fixedly mounted on the circular plate 13, a first limiting plate 1801 fixedly mounted on the lifting shaft 18 and abutting against the first push block 1302, a first circular ring 1803 fixedly mounted on the first limiting plate 1801 and coaxial with the lifting shaft 18, and a first arc-shaped compression spring 1804 sleeved on the first circular ring 1803. The first circular ring 1803 is slidably plugged into the first push block 1302, one end of the first arc-shaped compression spring 1804 abuts against the first limiting plate 1801, and the other end abuts against the first push block 1302. Figure 4 As shown, the elastic force of the first arc-shaped compression spring 1804 causes the first push block 1302 to abut against the first limiting plate 1801 in the initial state. The circular plate 13 is always in a compressed state. When the fixed rod 12 pushes the circular plate 13 to rotate, the circular plate 13 drives the first push block 1302 to rotate synchronously along the first circular ring 1803. The first push block 1302 squeezes the first arc-shaped compression spring 1804, causing further elastic compression deformation, thereby enabling the circular plate 13 to achieve elastic rotation. When the force exerted by the fixed rod 12 on the circular plate 13 disappears, the elastic force of the first arc-shaped compression spring 1804 is released to push the first push block 1302 to abut against the first limiting plate 1801 again, thereby restoring the circular plate 13.

[0035] In this embodiment, the tool assembly includes a seesaw 14, which is rotatably connected to the circular plate 13 through a shaft 1401. The shaft 1401 is rotatably plugged into the seesaw 14 and fixedly connected to the two circular plates 13. A cutter head 1402 is fixedly installed on the end of the seesaw 14, and an upper limit block 15 and a lower limit block 24 are fixedly installed on the circular plate 13. The end of the seesaw 14 away from the cutter head 1402 passes between the upper limit block 15 and the lower limit block 24 and abuts against the stop rod 8. The stop rod 8 is fixedly mounted on the support body 1. The stop rod 8 and the circular plate 13, the pressure roller 17, the back glue 2, and the back glue roll wound on the winding roller 7 are all staggered. There is a gap between the lower limit block 24 and the seesaw 14. A compression spring 25 is connected, one end of the compression spring 25 is fixedly connected to the seesaw 14, and the other end is fixedly connected to the lower limit block 24. The compression spring 25 is always in a compressed state, and the elastic force of the compression spring 25 drives the seesaw 14 to abut against the upper limit block 15. When the circular plate 13 drives the tool assembly to rotate, the seesaw 14 abuts against the baffle rod 8, and under the blocking action of the baffle rod 8, the seesaw 14 is driven to rotate around the shaft 1401. The seesaw 14 compresses the compression spring 25 to further elastically deform, and drives the cutter head 1402 to move toward the pressure roller 17 to cut the back glue 2. When the baffle rod 8 is no longer abutting against the seesaw 14, the elastic force of the compression spring 25 is released to reset the tool assembly.

[0036] Furthermore, after the adhesive backing 2 is cut, the end of the adhesive backing roll on the winding roller 7 needs to be adhered to the adhesive backing roll, otherwise the adhesive backing roll on the winding roller 7 will automatically spread out. In the prior art, a separate bonding operation is performed on the end of the adhesive backing roll on the winding roller 7 at a later stage, which will undoubtedly increase the operating procedures and reduce work efficiency. To this end, in this embodiment, a support plate 1802 is detachably installed in the inner groove 1805 at both ends of the lifting shaft 18, and the support plate 1802 is installed in the corresponding inner groove 1805 by screws. A rotating shaft 21 is rotatably installed between the two support plates 1802, and a tape ring 20 is rotatably sleeved on the rotating shaft 21. A swing plate 23 is elastically rotatably provided on the rotating shaft 21 through a second elastic member. The structure of the second elastic member is the same or similar to that of the first elastic member. One preferred embodiment is that the second elastic member includes a second push block 2301 fixedly connected to the swing plate 23, a second limiting plate 2101 fixedly connected to the rotating shaft 21, a second ring 2102 fixedly connected to the second limiting plate 2101 and slidably plugged into the second push block 2301, and a ring 2102 sleeved on the second ring 2 102, the second arc compression spring 2103, the second ring 2102 is coaxial with the rotating shaft 21, one end of the second arc compression spring 2103 abuts against the second push block 2301, and the other end abuts against the second limiting plate 2101. The second arc compression spring 2103 is always in a compressed state. Based on the elastic force of the second arc compression spring 2103, the second limiting plate 2101 abuts against the second push block 2301 in the initial state to limit the swing plate 23, so that the swing plate 23 cannot rotate toward the winding roller 7 relative to the rotating shaft 21, but can follow the rotating shaft 21 to rotate toward the winding roller 7, and the swing plate 23 can elastically rotate relative to the rotating shaft 21 in the direction away from the winding roller 7. At this time, the swing plate 23 drives the second push block 2301 to rotate along the second ring 2102 to compress the second arc compression spring 2103. A squeezing roller 19 is rotatably mounted on the swing plate 23 and adheres to the single-sided tape 2001 on the tape ring 20. A rotating shaft 21 is linked to the circular plate 13 so that rotation of the circular plate 13 drives the rotating shaft 21. The rotational force of the rotating shaft 21 drives the swing plate 23 to drive the squeezing roller 19, squeezing the single-sided tape 2001 and causing it to adhere to the adhesive backing 2 being wound on the winding roller 7. Specifically, the outer circumference of the squeezing roller 19 is provided with a plurality of protruding pieces 1901, one or more of which are affixed with double-sided tape (not shown). The non-stick surface of the single-sided tape 2001 adheres to the double-sided tape on the protruding pieces 1901, with the adhesive surface of the single-sided tape 2001 facing the adhesive backing roll being wound on the winding roller 7.The principle is as follows: when the circular plate 13 is pushed and rotated by the fixed rod 12, the circular plate 13 drives the rotating shaft 21 to rotate, and the rotation of the rotating shaft 21 drives the swing plate 23 to rotate synchronously with the rotating shaft 21 through the second elastic member, and the rotation direction of the swing plate 23 is toward the back adhesive roll wound on the winding roller 7, and the swing plate 23 drives the squeezing roller 19 to rotate toward the back adhesive roll wound on the winding roller 7 until the squeezing roller 19 squeezes the back adhesive roll wound on the winding roller 7. Since the single-sided tape 2001 is adhered to the squeezing roller 19, the adhesive surface of the single-sided tape 2001 is squeezed and adhered to the back adhesive roll wound on the winding roller 7. The bonding force between the single-sided tape 2001 and the double-sided tape on the convex piece 1901 is less than the bonding force between the single-sided tape 2001 and the back adhesive roll wound on the winding roller 7, so that The single-sided adhesive tape 2001 is transferred to the adhesive roll wound on the take-up roller 7. As the take-up roller 7 continues to rotate, more single-sided adhesive tape 2001 gradually adheres to the adhesive roll wound on the take-up roller 7. The cutter assembly then contacts the stopper 8 and cuts the adhesive 2. After cutting, the take-up roller 7 continues to rotate, so that the single-sided adhesive tape 2001 adheres to the end of the adhesive roll on the take-up roller 7. This eliminates the need to adhere the end of the adhesive roll on the take-up roller 7 to the adhesive roll later. The adhesive roll on the take-up roller 7 can be removed after the single-sided adhesive tape 2001 is cut. After the single-sided adhesive tape 2001 is cut, it is re-adhered to the squeezing roller 19 so that the adhesive roll end of the adhesive roll on the take-up roller 7 can be continuously adhered to next time. In this embodiment, the squeezing roller 19 squeezes the adhesive roll wound on the take-up roller 7 first, and the cutter assembly cuts the adhesive 2 later.

[0037] The roller 21 is provided with a rotating shaft 21 connected to the lifting shaft 18, and the tape ring 20 is rotated and sleeved on the rotating shaft 21. The swing plate 23 is elastically rotated on the rotating shaft 21, and the squeezing roller 19 that is bonded to the single-sided tape 2001 on the tape ring 20 is rotatably provided on the swing plate 23. When the circular plate 13 rotates, the squeezing roller 19 can squeeze the adhesive roll wound on the winding roller 7, so that the single-sided tape 2001 adheres to the adhesive roll wound on the winding roller 7. Then the circular plate 13 drives the cutter assembly to cut the adhesive 2. As the winding roller 7 continues to rotate, the single-sided tape 2001 adheres the end of the adhesive roll wound on the winding roller 7 to the adhesive roll, that is, the automatic "sealing" of the adhesive roll wound on the winding roller 7 is achieved, eliminating the need to glue the end of the adhesive roll on the winding roller 7 to the adhesive roll in the later stage.

[0038] An inner ring body 2002 is rotatably sleeved on the rotating shaft 21 , and the tape ring 20 is wound around the inner ring body 2002 . The rotating connection between the tape ring 20 and the rotating shaft 21 is achieved by the rotating connection between the rotating shaft 21 and the inner ring body 2002 .

[0039] In this embodiment, the linkage between the circular plate 13 and the rotating shaft 21 is achieved by: a gear 22 is fixedly mounted on the rotating shaft 21, and one of the circular plates 13 is provided with meshing teeth 1303 on the outer circumference thereof, which mesh with the gear 22. When the circular plate 13 rotates, the meshing teeth 1303 drive the gear 22 and the rotating shaft 21 to rotate. When the rotating shaft 21 squeezes the circular plate 13 to rotate, the rotating shaft 21 rotates toward the winding roller 7. The rotating shaft 21 drives the swing plate 23 and the squeezing roller 19 toward the winding roller 7 via the second elastic member, so that the squeezing roller 19 elastically squeezes the adhesive rolled on the winding roller 7. Because the swing plate 23 is elastically rotatable on the rotating shaft 21 and can elastically rotate away from the winding roller 7, the squeezing roller 19 can also elastically rotate away from the winding roller 7, so that the squeezing roller 19 and the adhesive rolled on the winding roller 7 do not get stuck.

[0040] In this embodiment, after the cutter assembly cuts the adhesive 2, the tensioning member drives the squeezing roller 19 to fall synchronously. During the squeezing roller 19's fall, it elastically squeezes the adhesive 2 wound on the take-up roller 7, preventing the adhesive 2 wound on the take-up roller 7 from loosening. Specifically, after the cutter assembly cuts the adhesive 2, as the tensioning member falls from a specific height to its lowest position, the squeezing roller 19 continuously elastically squeezes the adhesive roll wound on the take-up roller 7. Under the elastic squeezing force of the squeezing roller 19, the single-sided adhesive tape 2001 is more firmly adhered to the adhesive roll on the take-up roller 7. The squeezing roller also squeezes the adhesive roll wound on the take-up roller 7, preventing the end of the adhesive roll from loosening before being adhered by the single-sided adhesive tape 2001. This allows the adhesive roll on the take-up roller 7 to be "sealed" by the single-sided adhesive tape 2001 in its wound state, thereby ensuring the quality of the adhesive roll. It can be seen that the design of the squeezing roller 19 has achieved unexpected technical effects.

[0041] In this embodiment, when the single-sided adhesive tape 2001 on the adhesive tape ring 20 is used up, it needs to be replaced. The replacement method is as follows: the length of the vertical section of the first chute 102 is the same as the length of the vertical section of the second chute and the height is the same, the length of the horizontal section of the first chute 102 is greater than the length of the horizontal section of the second chute. When the single-sided adhesive tape 2001 on the adhesive tape ring 20 is used up, the tensioning member is first pulled upward to make the two sliders 16 slide to the highest point along the vertical section of the first chute 102 and the vertical section of the second chute in a one-to-one correspondence, and then the tensioning member is pulled outward to make the two sliders 16 slides one by one to the transverse section of the first slide groove 102 and the transverse section of the second slide groove. Since the length of the transverse section of the first slide groove 102 is greater than the length of the transverse section of the second slide groove, when the slider 16 located in the second slide groove is moved out, the 106 located in the first slide groove 102 is still located in the transverse section of the first slide groove 102. Then, the slider 16 corresponding to the second slide groove is moved out from the lifting shaft 18, and then the corresponding support plate 1802 is disassembled to make one end of the rotating shaft 21 suspended in the air. Finally, the used tape ring 20 is removed and replaced with a new tape ring 20.

[0042] Among them, the adhesive rolled up on the winding roller 7 is staggered with the gear 22 and the tape ring 20, and the adhesive in the tensioned state is also staggered with the gear 22 and the tape ring 20.

[0043] Second embodiment: The structure of this embodiment includes all the structures of the first embodiment, except that: Figure 14 and 15 As shown, a protective plate 9 is fixedly mounted between the two circular plates 13. A clearance hole 901 is formed in the protective plate 9. Initially, the end of the cutter head 1402 is positioned within the clearance hole 901, ensuring that the adhesive 2 does not strike the cutter head 1402 when passing through the bottom of the pressure roller 17, thereby ensuring operational safety. When the cutter head 1402 moves toward the pressure roller 17 to cut the adhesive 2, the cutter head 1402 passes through the clearance hole 901, ensuring that the pressure roller 17 does not hinder the cutter head 1402 from cutting the adhesive 2.

[0044] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
