Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of packaging machinery equipment, and particularly relates to a viscous label peeling test device. BACKGROUND

[0002] As an important material in the packaging industry, the performance of the adhesive directly affects the stability and reliability of product packaging. In modern packaging technology, double-sided tape is widely used in packaging products such as gift boxes and color pages due to its good bonding performance and ease of use, and is used for connection and fixation of products. However, as the market's requirements for the performance and appearance of packaging products continue to increase, especially in the global sales scenario, packaging materials need to meet complex requirements such as multi-language label differentiation, easy label peeling, and appearance integrity, and traditional adhesive testing methods cannot fully meet actual needs.

[0003] Currently, to test the peeling performance of the adhesive, the traditional equipment peels the adhesive tape from the standard steel plate through clamps to measure the peeling force. However, this testing method and device have some shortcomings, for example, in the traditional equipment, due to the lack of synchronous movement mechanism of the upper and lower clamps, the test angle may deviate during the peeling process, especially in the case of special-shaped adhesive tape or high-precision testing, which cannot guarantee the consistency and precision of the peeling force measurement. This angle deviation will directly affect the reliability of the test results, and even cause the measurement data to be invalid. CONTENT OF THE UTILITY MODEL

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0029] Reference is made to Figs. 1 to 3 :

[0030] The present application first provides an embodiment of an adhesive label peeling test device, which comprises:

[0031] The upper clamp 01, the lower clamp 02, the transmission structure 03 and the adhesive piece 04;

[0032] The adhesive piece 04 is fixed on the lower clamp 02 and used for bonding one end of the adhesive label to be tested.

[0033] The upper clamp 01 is connected to a driving mechanism, one end of the transmission structure 03 is connected to the upper clamp 01, and the other end is connected to the lower clamp 02.

[0034] The upper clamp 01 is connected to a driving mechanism, one end of the transmission structure 03 is connected to the upper clamp 01, and the other end is connected to the lower clamp 02.

[0035] The upper clamp 01:

[0036] In this embodiment, the upper clamp 01 is a component for clamping one end of the adhesive label to be tested.

[0037] The upper clamp 01 fixes the adhesive label to be tested through the chuck assembly 011, which can increase the clamping stability and prevent the adhesive label to be tested from slipping off during the test.

[0038] The upper clamp 01 is connected to a driving mechanism, and when the driving mechanism works, the upper clamp 01 drives the clamped adhesive label to be tested to complete the peeling movement along the set direction (for example, 180°).

[0039] The lower clamp 02:

[0040] The lower clamp 02 is used for fixing the other end of the adhesive label to be tested, which is specifically realized through the adhesive piece 04.

[0041] The adhesive piece 04 is arranged on the workbench of the lower clamp 02 and can be realized in various fixing modes, for example, the magnetic fixing mode or the screw fixing mode.

[0042] In this application, the lower clamp 02 keeps synchronous movement with the upper clamp 01 during the peeling process, so that the test angle is always constant.

[0043] The transmission structure 03:

[0044] In this embodiment, one end of the transmission structure 03 is connected to the upper clamp 01, and the other end is connected to the lower clamp 02, and the synchronous movement of the lower clamp 02 with the upper clamp 01 is realized through the coordinated movement of the transmission structure 03.

[0045] In this application, the design of transmission structure 03 is the key part of the adhesive label peeling test device, its main function is to realize the synchronous movement of the upper clamp 01 and the lower clamp 02, so as to ensure the constant peeling angle. Some possible ways to realize the transmission structure 03 are provided as follows:

[0046] 1. Gear transmission: use gear meshing to transmit motion. The upper clamp 01 is connected with the driving gear, and the lower clamp 02 is connected with the driven gear. When the driving gear rotates, the driven gear moves synchronously.

[0047] 2. Chain or belt transmission: connect the upper clamp 01 and the lower clamp 02 through chain or belt, and transmit synchronous motion when the driving sprocket or pulley rotates.

[0048] 3. Linkage mechanism: connect the upper clamp 01 and the lower clamp 02 through rigid link, drive the upper clamp 01 to move, and drive the lower clamp 02 to move synchronously through the link.

[0049] 4. Slide rail linkage mechanism: link the upper clamp 01 and the lower clamp 02 through the slide rail. When the upper clamp 01 moves, it drives the lower clamp 02 at the other end of the slide rail to move synchronously.

[0050] 5. Synchronous belt / synchronous pulley mechanism: connect the upper clamp 01 and the lower clamp 02 through the cooperation of synchronous belt and synchronous pulley to realize synchronous motion.

[0051] Specifically, the way to realize the synchronous movement of the upper clamp 01 and the lower clamp 02 is not limited here.

[0052] Adhesive member 04:

[0053] The adhesive member 04 is used to fix one end of the adhesive label, and its surface can be replaced with different materials or adjusted in size according to different test requirements. In one optional implementation, the adhesive member 04 can be installed on the lower clamp 02 through a magnet, which is convenient for quick replacement or adjustment, and adapts to labels of different specifications or shapes.

[0054] Drive mechanism: the drive mechanism provides a power source to drive the upper clamp 01 to complete the peeling motion in a set direction.

[0055] The drive mechanism can select different motion speeds and strokes according to test requirements to meet the standards of different adhesive label tests. It should be noted that the drive mechanism provided in the adhesive label peeling test device is a key component to realize the peeling motion, and its main function is to provide driving force for the upper clamp 01 and indirectly drive the lower clamp 02 through the transmission structure 03, thereby realizing the peeling test of the label.

[0056] The drive mechanism is responsible for providing the power source of motion. Specifically, it can be realized in the following ways:

[0057] Servo motor, stepper motor, hydraulic cylinder or air cylinder, or linear drive, etc. are not limited here.

[0058] The working principle of this embodiment is based on the coordinated action of the driving mechanism, the transmission structure 03, the upper clamp 01 and the lower clamp 02 to realize the synchronous peeling movement of the adhesive label at a certain peeling angle and speed.

[0059] Specifically, during operation, first, one end of the adhesive label to be tested is pasted on the adhesive member 04, which is fixedly installed on the lower clamp 02, so that the label is firmly pasted and accurately positioned.

[0060] Then, the other end of the adhesive label is inserted and clamped in the chuck assembly 011 of the upper clamp 01, ensuring that the label remains in a tensioned state.

[0061] The peeling angle of the device can be adjusted so that the upper clamp 01 and the lower clamp 02 are kept at a set peeling angle (usually a fixed angle, such as 90° or a specific angle). The peeling speed, peeling distance, and the mechanical parameter monitoring range of the test process (such as the maximum peeling force) are set in the control system. The driving mechanism (such as a servo motor, a stepper motor, or a hydraulic cylinder) is started according to the set parameters to generate a driving force. The driving force is converted into linear motion through some transmission members (such as ball screws or synchronous belts), driving the upper clamp 01 to move in the peeling direction (usually vertical or horizontal). The upper clamp 01 moves at a uniform speed or acceleration under the action of the driving mechanism, and the chuck assembly 011 clamps one end of the label, gradually peeling the adhesive label from the adhesive member 04 during the peeling process.

[0062] One end of the transmission structure 03 is connected to the upper clamp 01, and the other end is connected to the lower clamp 02. When the upper clamp 01 moves, the transmission structure 03 drives the lower clamp 02 to move synchronously through mechanical connection, ensuring that the lower clamp 02 maintains a set peeling angle and synchronous distance with the upper clamp 01. The lower clamp 02 moves relatively synchronously under the action of the transmission structure 03, maintaining the stability of the adhesive member 04 and preventing stress deviation during the label peeling process due to changes in relative position.

[0063] During the peeling process, the force sensor monitors the peeling force of the adhesive label in real time and transmits the data to the control system. The control system adjusts the speed or acceleration of the driving mechanism according to the data feedback from the sensor to ensure smooth peeling. During the peeling process, the system automatically records the peeling force curve and related parameters (such as the maximum peeling force and the average peeling force). These data are used to analyze the adhesive properties of the label and provide a reference for subsequent improvement of adhesive label materials or processes.

[0064] When the upper clamp 01 completes the set peeling distance, the driving mechanism stops running, and the upper clamp 01 and the lower clamp 02 remain in the final position. At this time, the adhesive label has been completely peeled or reached the set peeling length.

[0065] In this embodiment, the synchronous movement of the upper clamp 01 and the lower clamp 02 is ensured by the transmission structure 03, eliminating the peeling angle deviation problem caused by relative movement in traditional devices. The device provided in this embodiment has high automation capability, and the peeling process does not require manual intervention, improving test efficiency and consistency.

[0066] In an optional embodiment, the lower clamp 02 includes a sliding table 05 and a fixed seat 06, which are slidably connected.

[0067] In this embodiment, the sliding table 05 is part of the lower clamp 02, and its main function is to provide an adjustable moving platform. The adhesive member 04 is fixed on the sliding table 05. The bottom of the sliding table 05 can be provided with sliding rails or guide structures to enable smooth movement along the sliding direction of the fixed seat 06.

[0068] The fixed seat 06 serves as a support part of the sliding table 05 and can be installed on the main structure of the device to provide a guide rail for the sliding table 05. The inside or surface of the fixed seat 06 can contain rolling guide rails, linear sliding rails or other sliding mechanisms to achieve sliding and reduce sliding friction and improve accuracy.

[0069] Further, as mentioned in the previous embodiments, there are many specific implementation methods for the transmission structure 03, and this application provides an embodiment of a specific transmission structure 03. The transmission structure 03 of this embodiment includes a transmission cable 07 and a guide wheel 08, the guide wheel 08 is installed on the fixed seat 06, one end of the transmission cable 07 is fixed on the upper clamp 01, the other end is fixed on the sliding table 05, and part of the transmission cable 07 is wound around the guide wheel 08.

[0070] In this embodiment, the transmission structure 03 uses a combination of transmission cable 07 and guide wheel 08 to achieve synchronous movement of the upper clamp 01 and the lower clamp 02. The specific structure and working principle are described in detail as follows:

[0071] In this embodiment, the transmission cable 07 can be made of high-strength materials such as steel wire rope, Kevlar fiber rope, etc. to ensure that it does not stretch or break during movement.

[0072] One end of the transmission cable 07 is fixed to the bottom or side of the upper clamp 01 and is firmly connected by bolts, welding or other fastening devices. The other end is fixed to a specific position on the sliding table 05 to ensure the tension of the transmission cable 07.

[0073] When the upper clamp 01 moves, the lower clamp 02 is driven to move synchronously by the transmission cable 07.

[0074] The guide wheel 08 can be fixedly installed on the top or side of the fixed seat 06 and located on the path of the transmission cable 07.

[0075] The guide wheel 08 can be made of low-friction material (such as wear-resistant plastic or ball bearing steel) to reduce energy loss during the operation of the transmission cable 07. The outer edge of the guide wheel 08 can be provided with a wire groove 09 for guiding the transmission cable 07 to run along a specific path and preventing the transmission cable 07 from detaching or sliding. According to the wiring requirements of the transmission path, one or more guide wheels 08 can be provided to ensure the smooth operation of the transmission cable 07. The guide wheel 08 is installed on the fixed seat 06, which provides stable support for the guide wheel 08. The sliding table 05 is connected to the guide wheel 08 through the transmission cable 07, and the movement of the transmission cable 07 directly acts on the sliding table 05, thereby realizing synchronous movement.

[0076] In an optional embodiment, a return spring 10 is connected between the sliding table 05 and the fixed seat 06.

[0077] In this embodiment, in order to further optimize the performance of the device, a return spring 10 is connected between the sliding table 05 and the fixed seat 06 to realize the automatic reset function of the lower clamp 02. The spring can be selected to use a compression spring or a tension spring. The two ends of the return spring 10 are connected to the fixed points of the sliding table 05 and the fixed seat 06, respectively.

[0078] In the initial state of work, the sliding table 05 and the fixed seat 06 are in the initial position, and the return spring 10 is in the natural state without additional stretching or compression. When the upper clamp 01 drives the lower clamp 02 (sliding table 05) to move in the stripping direction through the transmission cable 07, the return spring 10 is stretched or compressed to store potential energy. During the movement, the return spring 10 does not interfere with the synchronous movement of the sliding table 05, but only plays a role in energy storage. After the test is completed, the upper clamp 01 stops moving, and the transmission structure 03 no longer drives the sliding table 05. At this time, the return spring 10 releases the stored potential energy and pushes the sliding table 05 back to the initial position. The force of the return spring 10 smoothly pulls the sliding table 05 back to the initial position of the fixed seat 06. The reset of the sliding table 05 makes the lower clamp 02 ready for the next test operation.

[0079] In this embodiment, in the scenario of multiple repeated stripping tests, the design of the return spring 10 can effectively reduce the operation steps and improve the test efficiency. In the case where additional driving mechanisms cannot be used, the return spring 10 provides a space-saving solution.

[0080] In one optional embodiment, the chuck assembly 011 includes an upper chuck 11, a lower chuck 12, and an adjusting screw 13. The upper chuck 11 and the lower chuck 12 are rotatably connected. The upper chuck 11 is provided with a through hole 14, and the adjusting screw 13 passes through the through hole 14 and is threadedly connected to the lower chuck 12.

[0081] In this embodiment, to enhance the adjustability and reliability of the chuck assembly 011, the chuck assembly 011 includes an upper chuck 11, a lower chuck 12, and an adjusting screw 13. The following is a detailed description of the structure and working principle of this embodiment.

[0082] First, the structural composition of this optional embodiment will be described:

[0083] Upper clamp 11:

[0084] The upper chuck 11 is the upper clamping component for holding the adhesive label to be tested. It is rotatably connected to the lower chuck 12 via a pivot, ensuring flexible adjustment of the chuck within a certain range. The upper chuck 11 is provided with a through hole 14, the inner surface of which can be smoothed to reduce friction when the adjusting screw 13 rotates.

[0085] Lower chuck 12:

[0086] The lower clamp 12 is the lower clamping component that holds the adhesive label to be tested. It is connected to the upper clamp 11 via a pivot, and the clamping force is adjusted by adjusting the screw 13. The surface of the lower clamp 12 may have a certain friction treatment (such as using a rubber pad or textured design) to enhance the clamping force on the adhesive label.

[0087] Specifically, the heads of the upper chuck 11 and the lower chuck 12 are wedge-shaped. This specific embodiment optimizes the structural design of the chuck assembly 011 by designing the heads of the upper chuck 11 and the lower chuck 12 as wedge-shaped.

[0088] The heads of the upper clamp 11 and lower clamp 12 have been changed from traditional flat clamps to wedge-shaped structures, with a sharp bevel or a slender wedge shape. The tip of the wedge is close to the adhesive surface of the label, allowing for more precise gripping of the label's edge. The wedge-shaped head design enables the clamps to concentrate and apply greater clamping force, especially for small labels where the gripping surface is small but requires greater pressure to prevent slippage.

[0089] The wedge-shaped structure's inclined contact effectively increases the contact pressure per unit area, resulting in a more secure grip on small labels. The pointed end of the wedge facilitates precise positioning of the small label's edge, preventing testing errors caused by inaccurate gripping. Especially for small labels with thin edges, the wedge structure provides a stable gripping effect.

[0090] Adjusting screw 13:

[0091] Adjusting screw 13 passes through the through hole 14 of the upper clamp head 11 and is screwed with the lower clamp head 12.

[0092] The screw is provided with a knob or hexagonal head for manual or tool-assisted rotation. By rotating the adjusting screw 13, the distance between the upper clamp head 11 and the lower clamp head 12 can be changed, thereby adjusting the clamping force.

[0093] In operation, the upper clamp head 11 and the lower clamp head 12 are connected by the rotating shaft. When the adjusting screw 13 is not rotated, the two clamp heads are in an initial gap state. The adjusting screw 13 passes through the through hole 14 of the upper clamp head 11 and is connected with the threaded hole of the lower clamp head 12. When the adjusting screw 13 is rotated, the distance between the upper clamp head 11 and the lower clamp head 12 changes due to the action of the thread. After adjustment is completed, the clamp head assembly 011 applies a peeling force through the driving device of the upper clamp head 11. Since the clamping force of the clamp head assembly 011 is precisely controlled by the adjusting screw 13, the label will not slip or fall off during the test. After the test is completed, the adjusting screw 13 is rotated counterclockwise to loosen the distance between the clamp heads, thereby facilitating the removal of the tested adhesive label.

[0094] Further, the adjusting screw 13 is provided with a pre-tightening spring 15.

[0095] In order to further optimize the adjustment performance and clamping stability of the clamp head assembly 011, a pre-tightening spring 15 is provided on the adjusting screw 13. The pre-tightening spring 15 is provided on the adjusting screw 13 and located between the through hole 14 of the upper clamp head 11 and the screw knob (or hexagonal head). A limiting device can also be provided on the adjusting screw 13 to fix the position of the spring and prevent the spring from falling off. The specific form can be a threaded fixed washer, a snap ring, or a protruding limiting section directly machined on the screw. When the adjusting screw 13 is initially installed, the pre-tightening spring 15 is in a certain compression state, and the elastic force of the spring is transmitted to the upper clamp head 11 through the limiting structure. This pre-tightening force makes the upper clamp head 11 always generate an initial downward pressure on the lower clamp head 12, so that the adhesive label can be clamped even if the screw is not completely locked.

[0096] During the movement of the peeling test, the pre-tightening spring 15 provides continuous elastic compensation force to prevent the clamp from loosening or the clamping force from being unstable due to vibration or slight deviation.

[0097] When subjected to instantaneous impact force, the spring can act as a buffer to prevent the clamp from being damaged directly by excessive force. After the test is completed, the upper clamp head 11 is restored to the initial position under the push of the spring by completely loosening the adjusting screw 13, facilitating the removal of the adhesive label by the operator.

[0098] By setting the pre-tightening spring 15 on the adjusting screw 13, the clamping performance and operation convenience of the device are further optimized, and the applicability and reliability of the adhesive label peeling test device are enhanced.

[0099] In an optional embodiment, a fixed pressing plate 16 is further included, which is arranged above the adhesive member 04, and a notch 17 is formed on the fixed pressing plate 16, the shape of the notch 17 is consistent with the shape of the adhesive label to be tested.

[0100] In this optional embodiment, the adhesive label peeling test device adds the design of the fixed pressing plate 16 to improve the stability and accuracy of the test. The fixed pressing plate 16 is arranged above the adhesive member 04 to cover the adhesive area of the adhesive label to be tested. The fixed pressing plate 16 can be made of rigid materials (such as metal or hard plastic) to ensure that it does not deform or shift during the peeling process. A notch 17 is formed on the fixed pressing plate 16, which is consistent with the shape of the adhesive label to be tested. The shape of the notch 17 is customized according to the actual profile of the label to be tested, which can completely fit the outer edge of the label, ensuring that the exposed part of the label is in close contact with the clamp during the test.

[0101] During the peeling process, the pasted part of the adhesive label to be tested may be raised or shifted due to stress, and the fixed pressing plate 16 limits its movement through the covering effect to ensure that the pasted area remains stable during the test.

[0102] The label bears a certain pulling force during the peeling test, and the design of the notch 17 of the fixed pressing plate 16 can evenly distribute the pressure to avoid local stress concentration causing the label to break.

[0103] The fixed pressing plate 16 ensures that the non-peeling part of the adhesive label to be tested is always flatly adhered to the adhesive member 04, reducing the error introduced by the movement or lifting of the label during the test.

[0104] The design of the notch 17 can be adjusted according to labels of different shapes, so that the device can adapt to the test of labels of various shapes (such as circular, rectangular, or irregular shapes), improving the versatility of the device.

[0105] During the test, first, one end of the adhesive label to be tested is adhered to the adhesive member 04, and the other end is clamped in the chuck assembly 011.

[0106] The fixed pressing plate 16 is covered on the upper side of the adhesive member 04, so that the adhesive part of the label is completely located between the pressing plate and the adhesive member 04, and the test part of the label is exposed from the notch 17. After starting the test, the driving mechanism drives the upper clamp 01 to move, and the transmission structure 03 synchronously drives the lower clamp 02 to move. The fixed pressing plate 16 limits the adhesive part of the adhesive label to remain stable, and the peeling force test is carried out under fixed conditions.

[0107] In this optional embodiment, the performance of the adhesive label peeling test device is further improved by adding the fixed pressing plate 16 and the notch 17 design.

[0108] In a further embodiment, a magnetic attraction member 18 is also included, and the fixed pressing plate 16 fixes the adhesive member 04 on the upper clamp 01 through the magnetic attraction member 18.

[0109] In this embodiment, the magnetic attraction member 18 is added to the adhesive label peeling test device. Specifically, the magnetic attraction member 18 can include a set of magnetic components, which can be made of strong magnetic materials (such as neodymium iron boron magnets) to ensure sufficient adsorption force. The magnetic attraction member 18 is distributed in the contact area between the fixed pressing plate 16 and the adhesive member 04 to achieve firm adsorption and fixation.

[0110] The magnetic attraction member 18 can be one or more magnetic attraction pressing blocks made of high-strength magnetic materials (such as neodymium iron boron magnets) with sufficient adsorption force. The bottom of the magnetic attraction pressing block is a flat magnetic surface that is adsorbed with the metal layer above the fixed pressing plate 16 or the area embedded with magnetic material. The shape of the magnetic attraction pressing block can be designed as a circle, a rectangle, or other shapes, depending on the size of the fixed pressing plate 16 and the testing requirements of the adhesive label. One or more magnetic attraction pressing blocks can be used according to the size of the fixed pressing plate 16 and the testing strength requirements of the label. For larger fixed pressing plates 16, multiple magnetic attraction pressing blocks can be evenly distributed to ensure uniform distribution of adsorption force.

[0111] Some preferred embodiments in this application are provided below:

[0112] Embodiment one:

[0113] An embodiment of an adhesive label peeling test device, which includes:

[0114] The upper clamp 01, the lower clamp 02, the transmission structure 03, and the adhesive member 04;

[0115] The adhesive member 04 is fixed on the lower clamp 02 and is used to adhere one end of the adhesive label to be tested. The upper clamp 01 is fixedly provided with a chuck assembly 011 for clamping the other end of the adhesive label.
