Description

Technical Field

[0001] This utility model relates to the technical field of equipment for obtaining test samples, and in particular to an online tape sampling device. Background Technology

[0002] Tape and roll generally refer to a product that processes specific materials into rolls for easy storage, transportation and use. It is an item that rolls up materials for sealing, fixing or other purposes.

[0003] When producing tape rolls, it is usually necessary to ensure basic requirements such as surface flatness, surface cleanliness, corrosion resistance, and stability. Therefore, the produced tape rolls need to be tested to determine whether the surface flatness and cleanliness are up to standard. In order to test the tape rolls, a portion of the tape in contact with the surface needs to be used as a test sample. By testing the sample, the quality of the produced tape rolls can be judged to meet the standards.

[0004] Existing tape production typically involves manual random material selection and cutting, which necessitates pausing tape conveying when cutting sample pieces. Pausing tape production affects the continuous conveying of the tape, thereby impacting the efficiency and stability of tape production. Utility Model Content

[0005] The purpose of this invention is to provide an online tape sampling device that solves the problem of tape production and conveying efficiency and stability being affected by tape pausing during sampling, reduces the possibility of machine downtime during tape production and conveying, and thus improves the efficiency and stability of tape production and conveying.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an online strip sampling device, comprising a frame and a drive mechanism disposed on the upper part of the frame, a worktable disposed on the lower part of the frame, a support component disposed on the upper surface of the worktable, the support component being used to support the strip, and a stamping and shearing die disposed at the lower end of the drive mechanism, the drive mechanism driving the stamping and shearing die to abut against the support component and cut the strip to obtain a sample block.

[0007] After adopting the above technical solution, this utility model has the following advantages: The frame is installed on the tape production and conveying equipment, with the specific location selected according to the position of the sample to be obtained. After the frame is installed, a workbench and support assembly are provided at the lower part of the frame. The tape is supported on the support assembly, thereby positioning and supporting the tape, stabilizing the tape conveying while facilitating sample acquisition. A drive mechanism is provided at the upper part of the frame, and a stamping and shearing die is provided at the lower end of the drive mechanism. The drive mechanism drives the stamping and shearing die to move downwards, causing the stamping and shearing die to press down on the tape supported on the support assembly, thereby obtaining the sample to be tested. The test sample blocks reduce the difficulty of manual cutting and improve the convenience of sample block acquisition. The cutting is performed by a stamping and shearing die, ensuring the uniformity of the size of the acquired sample blocks. The machine is set on the conveyor belt production equipment. When acquiring the sample block, the drive mechanism drives the stamping and shearing die downward to cut. The timing of the cutting can be determined according to the rhythm of the conveyor belt, or the frequency and speed of the drive mechanism driving the stamping and shearing die downward can be adjusted manually. This allows the conveyor belt to acquire the sample block without stopping the conveyor belt, ensuring the efficiency and stability of the conveyor belt production.

[0008] Furthermore, the stamping and shearing die includes a top plate, a first elastic element, a bottom plate, and a punch. The top plate is located at the lower end of the driving mechanism, the first elastic element is located on the lower surface of the top plate, the bottom plate is located at the bottom end of the first elastic element, and the punch is fixedly located on the lower surface of the top plate and between the top plate and the bottom plate. After the bottom plate abuts against the support assembly, it compresses the first elastic element so that the punch extends out of the lower surface of the bottom plate to shear the coil.

[0009] Using the aforementioned technical solution, the stamping and shearing die is configured to include a top plate, a first elastic element, a bottom plate, and a punch. The top plate is used to fix the stamping and shearing die on the drive mechanism, which facilitates the drive mechanism to move the stamping and shearing die downward and shear the coil. After the bottom plate moves downward, it presses the coil to be sheared against the support component, stabilizing the coil to be sheared and improving the quality of the sheared sample. The first elastic element ensures, on the one hand, that the punch does not contact the coil when it is not pressed down, thus affecting the stability of the coil. On the other hand, after the first elastic element is compressed, the punch can extend out of the lower surface of the bottom plate to shear, ensuring that the punch can extend out of the bottom plate to obtain the sample.

[0010] Furthermore, the base plate is provided with a through groove running through the base plate in the vertical direction, and the bottom end of the punch passes through the through groove and abuts the coil against the worktable to obtain a sample block.

[0011] By adopting the aforementioned technical solution, a through groove is provided on the base plate in the vertical direction, allowing the lower end of the punch to extend through the through groove to the lower side of the base plate. This facilitates the punch extending from the lower side of the base plate to cut the roll, thereby improving the stability of the sample obtained by cutting the roll.

[0012] Furthermore, the thickness of the base plate is D1, the distance between the lower surface of the top plate and the upper surface of the base plate when the base plate is not in contact with the support component is D2, and the length of the punching blade in the distribution direction of the base plate and the top plate is L, where D2 < L ≦ D1 + D2.

[0013] Using the aforementioned technical solution, the length L of the punch blade in the distribution direction of the bottom plate and top plate is set to D2 < L ≦ D1 + D2. When the bottom plate has a through groove, D2 < L, ensuring that when the bottom plate does not abut against the roll, the bottom end of the punch blade is located in the through groove, ensuring that the bottom end of the punch blade can extend to the underside of the bottom plate to cut the roll. The setting of L ≦ D1 + D2 ensures that when the bottom plate does not abut against the roll, the bottom end of the punch blade does not extend to the underside of the bottom plate; ensuring that the punch blade can stably extend to the underside of the bottom plate, and at the same time ensuring the stability of the roll at the cut point during cutting, thereby improving the quality of the obtained sample.

[0014] Furthermore, the first elastic element is provided in multiple sets, and the multiple sets of the first elastic element are distributed between the top plate and the bottom plate.

[0015] Using the aforementioned technical solution, multiple sets of first elastic elements are provided, and these multiple sets of first elastic elements are evenly distributed between the bottom plate and the top plate, so that the bottom plate abuts against the thickness of the roll, and the bottom plate and the top plate can maintain relative horizontality, ensuring the stability of the roll when it is sheared, and reducing the possibility that the bottom plate deflection will cause one side of the roll to be stable while the other side is raised, thus affecting the quality of the sample.

[0016] Furthermore, the support assembly includes a support rod and a second elastic element. The second elastic element is disposed on the worktable, and the support rod is disposed on the upper end of the second elastic element. After the bottom plate moves downward, it presses against the support rod to compress the second elastic element and allow the punching blade to press the coiled strip to obtain a sample block.

[0017] Using the aforementioned technical solution, the support assembly is configured as a support rod and a second elastic element. The second elastic element is located on the worktable, and the support rod is located at the upper end of the second elastic element. The support rod supports the tape roll, and the second elastic element supports the support rod. During the shearing process, the base plate first presses against the support rod, and then the support rod compresses the second elastic element downwards, so that the second elastic element buffers the base plate and the support rod, reducing the possibility of collision between the base plate and the support rod. When the base plate and the support rod compress the second elastic element downwards, the punch gradually punches the tape roll, thereby obtaining the sample block to be tested on the tape roll.

[0018] Furthermore, two support rods are distributed in parallel along the horizontal direction to stably support the base plate.

[0019] By adopting the aforementioned technical solution, two support rods are distributed in parallel along the horizontal direction, and the base plate is pressed against the support rods. The two support rods support the base plate from both sides, thereby improving the stability of the base plate after pressing against the support rods, thus improving the flatness of the coiled strip, avoiding tilting of the coiled strip during the stamping and shearing process, and improving the quality of the obtained sample.

[0020] Furthermore, the length direction of the two support rods is the same as the conveying direction of the belt, and each end of the two support rods is provided with a rotating roller, which is rotatably connected to the support rod for conveying the belt.

[0021] By adopting the aforementioned technical solution, the length direction of the two support rods is set to be the same as the conveying direction of the belt, and then a rotating roller is connected to the end of the two support rods respectively, so that the belt contacts the rotating roller. The rotation of the rotating roller facilitates the conveying of the belt and reduces the possibility of the belt being in continuous contact with the support rod, which may affect the production and conveying of the belt.

[0022] Furthermore, the workbench is provided with a stamping support platform, which is located between two support rods to support the roll to be sampled, and the middle part of the stamping support platform is provided with a receiving groove for accommodating the sample block.

[0023] By adopting the aforementioned technical solution, a stamping support platform is set on the workbench. When the punch is used for sampling, it is pressed against the stamping support platform, which reduces the difficulty of punch sampling. By setting a receiving groove in the middle part of the stamping support platform to accommodate the sample block, the influence of the sample block on the conveyor belt is reduced, and the possibility of sample block loss due to the conveyor belt driving the sample block is reduced.

[0024] Furthermore, the workbench is equipped with a column, through which a lifting workbench that can slide up and down is installed. A drive mechanism drives the lifting workbench to rise and fall. The stamping and shearing die is located on the lifting workbench and rises and falls with the lifting workbench.

[0025] Using the aforementioned technical solution, a column is set on the workbench, through which a lifting workbench is installed. A drive mechanism moves the lifting workbench up and down, and the stamping and shearing die is placed on the lifting workbench. The lifting workbench ensures the stability of the stamping and shearing die's movement and avoids the possibility of tilting when the stamping and shearing die is shearing the coil, which could affect the quality of the sample.

[0034] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0035] like Figure 1As shown, this utility model provides an online tape sampling device, including a frame 1 and a drive mechanism 2 located on the upper part of the frame 1. The frame 1 is usually installed on the tape production and conveying equipment, and the specific position is selected according to the position of the sample block to be obtained. The lower part of the frame 1 is provided with a worktable 11, and the upper surface of the worktable 11 is provided with a support component 3. The tape is conveyed from the upper side of the support component 3. The lower end of the drive mechanism 2 is provided with a stamping and shearing die 4. The tape is located between the support component 3 and the stamping and shearing die 4, and the support component 3 supports the tape. During the production and conveying process, the user can randomly start the drive mechanism 2, or control the drive mechanism through a controller. The start and stop of mechanism 2 are achieved by driving mechanism 2 to drive the stamping and shearing die 4 to press down against the support component 3 and cut the roll to obtain a sample. During the sample acquisition process, the production equipment of the roll does not need to stop running, avoiding the impact on the production and conveying of the roll when the test sample acquisition is interrupted. Obtaining the sample through the stamping and shearing die 4 can ensure that the size of the obtained sample is appropriate. Compared with manual acquisition, it reduces the difficulty of obtaining the sample, the size of the obtained sample is more appropriate, and the efficiency of obtaining the sample is improved. At the same time, online sampling can be carried out, and the roll can be continuously produced and conveyed, reducing the need for the production and conveying equipment of the roll to stop, which affects the efficiency and stability of the roll production and conveying.

[0036] To ensure the stability of the lifting of the stamping and shearing die 4, such as Figure 1 As shown, the worktable 11 is provided with columns 111, through which a lifting worktable 112 that can slide up and down is passed. The drive mechanism 2 is located on the frame 1 and its lower end is connected to the lifting worktable 112. The stamping and shearing die 4 is installed on the lower surface of the lifting worktable 112. The drive mechanism 2 drives the stamping and shearing die 4 to slide up and down through the lifting worktable 112. There are multiple columns 111, and multiple columns 111 pass through the lifting worktable 112 at the same time, so that the lifting worktable 112 slides relative to multiple columns 111 during the lifting process, ensuring the stability of the lifting worktable 112 during the lifting process, reducing the possibility of the stamping and shearing die 4 tilting, and thus ensuring the quality of the sample after shearing.

[0037] Specifically, such as Figure 1 and Figure 2As shown, the stamping and shearing die 4 includes a top plate 41, a first elastic element 42, a bottom plate 43, and a punch 44. The top plate 41 is located on the lower surface of the lifting worktable 112, so that the top plate 41 is connected to the lower end of the drive mechanism 2. The first elastic element 42 is located on the lower surface of the top plate 41, and the first elastic element 42 extends downward and parallel to the length direction of the column 111. The bottom plate 43 is located at the bottom end of the first elastic element 42. The punch 44 is fixed to the lower surface of the top plate 41 and extends toward the bottom plate 43, so that the punch 44... Located between the bottom plate 43 and the top plate 41; more specifically, the bottom plate 43 is provided with a through groove 431 that runs through the bottom plate 43 in the vertical direction. The drive mechanism 2 drives the top plate 41 and the bottom plate 43 to move downward. When the bottom plate 43 presses against the roll, the first elastic member 42 between the bottom plate 43 and the top plate 41 is compressed, which reduces the distance between the upper surface of the bottom plate 43 and the lower surface of the top plate 41, so that the punch 44 extends out from the through groove 431 and cuts the roll below the bottom plate 43, thereby obtaining the sample to be tested.

[0038] In this embodiment, as Figure 3 and Figure 4 As shown, the thickness of the base plate 43 is D1, and the distance between the lower surface of the top plate 41 and the upper surface of the base plate 43 when the base plate 43 is not in contact with the support component 3 is D2. The length of the punch 44 in the distribution direction of the base plate 43 and the top plate 41 is L, where D2 < L ≦ D1 + D2. D2 < L ensures that the lower end of the punch 44 is located in the through groove 431, allowing the punch 44 to extend from the through groove 431 to the lower side of the base plate 43 during the compression of the first elastic member 42, ensuring that the punch 44 can extend downwards to the lower side of the base plate 43 to cut the coil. The setting of L ≦ D1 + D2 ensures that the base plate 43 is not in contact with the support component 3. When the tape is being fed, the punch 44 will not extend beyond the lower surface of the base plate 43 as the top plate 41 descends. Because the base plate 43 and the top plate 41 are connected by the first elastic element 42, the base plate 43 may sway left and right during its descent. If the base plate 43 does not contact the tape, the setting of L≦D1+D2 ensures that the bottom end of the punch 44 does not extend beyond the through groove 431 to the lower side of the base plate 43 when the base plate 43 does not contact the tape. This avoids the base plate 43 not pressing against the tape, and the tape conveying causes wear between the punch 44 and the upper surface of the tape, which would affect the quality of the obtained sample.

[0039] To ensure the stability of the base plate 43 pressing against the support assembly 3, multiple sets of first elastic members 42 are provided between the top plate 41 and the base plate 43. The multiple sets of first elastic members 42 are distributed between the top plate 41 and the base plate 43 to improve the stability of the base plate 43 and prevent the lower surface of the base plate 43 from tilting.

[0040] Specifically, such as Figure 4As shown, the shape of the lower end of the punch 44 is set according to the shape of the required sample block. The lower surface of the punch 44 is concave upward to form a groove 441, so that the outer edge of the lower end of the punch 44 forms a cutting edge. When the punch 44 punches the coil, the cutting edge performs shearing. The groove 441 prevents the bottom end of the punch 44 from abutting against the coil, which would affect the flatness of the sample block surface and thus affect the test effect of the sample block.

[0041] In another embodiment, such as Figure 1 and Figure 5 As shown, the support assembly 3 includes a support rod 31 and a second elastic element 32. The second elastic element 32 is disposed on the worktable 11 and extends upward. The support rod 31 is disposed at the upper end of the second elastic element 32. After the base plate 43 moves downward, it presses against the support rod 31 to compress the second elastic element 32 and allow the punching blade 44 to punch the tape roll to obtain a sample block. Specifically, two support rods 31 are distributed in parallel along the horizontal direction to stably support the base plate 43. The length direction of the two support rods 31 is the same as the conveying direction of the tape roll. The ends of the two support rods 31 are connected by a rotating roller 311. When the tape roll is being conveyed normally, the tape roll contacts the two rotating rollers 311, reducing the influence of the support rods 31 on the tape roll conveying.

[0042] To facilitate sampling by the punch blade 44, such as Figure 5 As shown, a stamping support platform 113 is provided on the workbench 11. The stamping support platform 113 is located between two support rods 31 to support the coil to be stamped and sheared. The middle part of the stamping support platform 113 is provided with a receiving groove 1131 for accommodating the sample block. By setting the receiving groove 1131, the coil is prevented from being pressed against the stamping support platform 113 by the punch 44, and the lower surface of the coil is prevented from abutting against the stamping support platform 113, which would cause wear on the lower surface of the coil.

[0043] In another embodiment, the workbench 11 is provided with a sliding component. The sliding component drives the stamping support table 113 to slide along the width direction of the roll. After the sample block to be tested is sampled, the sliding component is activated to drive the stamping support table 113 to move linearly along the width direction of the roll away from the roll, so that the worker can take the cut sample block from the stamping support table 113. The sliding component can be a combination of a cylinder, a hydraulic cylinder or a motor screw, or other common devices that can drive the stamping support table 113 to move linearly.

[0044] Specifically, the drive mechanism 2 can be a hydraulic cylinder. The use of a hydraulic cylinder can ensure the shearing force during stamping and shearing, ensuring that the strip can be cut off during stamping and shearing. In another embodiment, the drive mechanism 2 can also be a pneumatic cylinder or other equipment that can drive the stamping and shearing die 4 to rise and fall.

[0045] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
