[0002] When conducting product quality assessments, tile grout manufacturers simulate the possibility of tile grout falling to the ground during construction, performing extreme drop tests on the product's performance. The grout tube is used to hold the grout, and its drop performance needs to be evaluated when the raw materials used in its production are changed. Drop testing is a common safety test, determining the extreme height at which the grout tube can be dropped, simulating a product's fall during use, to verify whether the product poses a danger upon drop or assesses its durability under impact during use.

Detailed Implementation

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0025] When conducting product quality assessments, tile grout manufacturers simulate the possibility of tile grout falling to the ground during construction, performing extreme drop tests on the product's performance. The grout tube is used to hold the grout, and its drop performance needs to be evaluated when the raw materials used in its production are changed. Drop testing is a common safety test, determining the extreme height at which the grout tube can be dropped, simulating a product's fall during use, to verify whether the product poses a danger upon drop or assesses its durability under impact during use.

[0026] However, in the existing technology, most common drop test methods are as follows: the tester holds the test sample with his hand and places it on a platform at a specified height, then lets the test sample fall freely from that height, and then puts the sample back on the platform and drops it again. This manual drop test is wasteful of manpower and inefficient.

[0027] This application provides an automatic drop test device for grout tubes, which can stably clamp irregularly shaped test products and accurately control the drop height of the test products, thereby effectively assessing the possibility of the products falling.

[0028] The following is in conjunction with the accompanying drawings in the instruction manual. Figures 1-5 A detailed description of the automatic drop test device for grout tubes is provided.

[0029] This application provides an automatic drop test device for grout tubes, wherein the tube is used to contain grout, and the automatic drop test device for grout tubes includes: a support frame 1; a fixing component 2, disposed on the support frame 1, capable of being fixedly installed within a preset area in the height direction of the support frame 1; and a clamping component 3, disposed on the fixing component 2, including a power component 31 and a gripper 32, wherein the power component 31 drives the gripper 32 to grip or release, the gripper 32 is used to fix the grout tube containing the grout, and the gripper 32 is adapted to the shape and size of the tube; wherein the support frame 1 can extend and retract in its own height direction to adjust its own height, and / or adjust the installation position of the fixing component 2 in the height direction of the support frame 1 to adjust the height between the clamping component 3 and the ground.

[0030] Specifically, the support frame 1 is telescopic, or the installation position of the fixing component 2 can be adjusted to allow the height of the clamping component 3 to precisely match different drop test standards, eliminating the need for additional tools or component replacements and improving testing efficiency. The gripper 32, driven by the power component 31, automatically releases the grout tube containing the sealant, suitable for grout tubes of different shapes, sizes, or weights, reducing manual intervention and operational risks. The fixing component 2 locks within a preset area of ​​the support frame 1, ensuring the support frame remains stable and does not shift during the drop, guaranteeing the verticality and repeatability of the sealant tube's free fall and improving test data accuracy. The fully automated height adjustment, product clamping, and product release simplify the testing process, making it particularly suitable for batch testing scenarios and significantly saving manpower and time costs. The automatic drop test device for sealant tubes avoids the risks of manual climbing or drop operations, making it safer and more reliable, especially for testing heavy or fragile items. Through height adjustment and automated clamping, this device achieves efficient, accurate, and safe drop testing, meeting diverse industrial testing needs.

[0031] In some optional embodiments, the support frame 1 includes a telescopic rod 11, one end of which is provided with a base 14, and a fixing component 2 is provided on the telescopic rod 11.

[0032] Specifically, the telescopic rod 11 integrates a height adjustment function. Its length can be quickly adjusted manually or electrically to precisely control the drop height, adapting to different testing standards such as 0.5m, 1m, and 1.5m. The base 14 enhances overall stability, preventing the support frame from tilting or swaying during testing, ensuring the free-fall trajectory of the tube containing the sealant is vertical, and improving test repeatability and accuracy. The telescopic rod 11 is retractable for easy transport or storage, suitable for various scenarios such as laboratories, production lines, or outdoor environments. The base 14 is designed to adapt to different ground surfaces, such as flat ground and inclined platforms, and can be further adapted to complex environments by adding counterweights or fixing bolts. The height can be set simply by adjusting the telescopic rod 11, making operation simple. Through the combination of the telescopic rod 11 and the base 14, while ensuring product stability and testing accuracy, convenient height adjustment, cost optimization, and scenario adaptability are achieved.

[0033] In some optional embodiments, the telescopic rod 11 includes a first rod 111, a second rod 112 and a limiting bolt 113. The first rod 111 has a plurality of first holes evenly arranged in its own length direction, the second rod 112 has a plurality of second holes arranged in its own length direction, and the limiting bolt 113 passes through one of the first holes and one of the second holes.

[0034] Specifically, the first rod 111 and the second rod 112 are respectively equipped with multiple evenly distributed first and second holes. By selecting different combinations of hole positions, discrete height adjustment can be achieved, such as in 50mm increments, ensuring that the drop height strictly meets the standard. Bolts are inserted through the aligned first and second holes and then tightened to form a rigid connection, preventing accidental slippage or loosening of the telescopic rod 11 during testing and ensuring the stability of the tube containing the grout during release. Height adjustment can be achieved simply by tightening the holes and bolts, resulting in low cost and a simple structure. By aligning different hole positions, a wider height range can be covered. After loosening the limiting bolt 113, the second rod 112 can be manually slid to the target height and then tightened again, with a short operation time. The bolt-locking mechanical connection can withstand the instantaneous impact force when the tube containing the grout is released during the drop test, preventing height deviation due to vibration.

[0035] In some optional embodiments, two telescopic rods 11 are provided, and the two telescopic rods 11 are arranged in parallel. The power component 31 includes a first cylinder 311 and a second cylinder 312. The gripper 32 includes a first arc plate 321 and a second arc plate 322. The first cylinder 311 and the second cylinder 312 are arranged face to face on the fixing component 2 of the two telescopic rods 11. The piston ends of the first cylinder 311 and the second cylinder 312 are fixed to the first arc plate 321 and the second arc plate 322.

[0036] Specifically, the two telescopic rods 11 form a symmetrical force-bearing structure, with parallel support from both rods 11. This prevents lateral tilting caused by the weight of the grout tube or impact from a drop when a single rod 11 is supporting the grout, ensuring that the clamping component 3 remains horizontal at all times. The first cylinder 311 and the second cylinder 312 are positioned face-to-face on the two telescopic rods 11, simultaneously pushing the first arc-shaped plate 321 and the second arc-shaped plate 322 from both sides. This achieves uniform clamping force on the grout tube, preventing displacement or deformation of the tube caused by unilateral pressure. The curved surface design of the first arc-shaped plate 321 and the second arc-shaped plate 322 creates a flexible clamping mechanism, which can conform to cylindrical, spherical, or irregularly shaped grout tubes, increasing the contact area and reducing localized stress damage. By controlling the extension and retraction of the cylinder pistons, the clamping distance can be flexibly adjusted to accommodate various size requirements, from small parts to large packaging boxes. The pneumatic drive of the first cylinder 311 and the second cylinder 312 can release the tube containing the sealant within milliseconds, ensuring a consistent starting state during free fall and avoiding manual errors during manual release. The clamping force and release timing for each drop test can be precisely controlled by the pneumatic system. The first cylinder 311 and the second cylinder 312 are directly fixed to the fixing component 2 of the two telescopic rods 11, forming an integral frame to further suppress vibration or shaking.

[0037] Furthermore, the two parallel telescopic rods 11 are connected by a connecting rod, which is connected to the end of the telescopic rod 11 away from the base 14.

[0038] In some optional embodiments, the fixing component 2 includes a first clamp 21 and a fixing plate 22, one end of the fixing plate 22 is disposed on the first clamp 21, the first clamp 21 is sleeved on the telescopic rod 11, and the power component 31 is disposed on the fixing plate.

[0039] Specifically, the first clamp 21 is fitted onto the telescopic rod 11. By loosening or tightening the first clamp 21, it can slide up and down along the telescopic rod 11, achieving stepless continuous adjustment of the height of the clamping component 3. This adapts to different drop test standards, such as 0.3m and 1.2m, without requiring disassembly of the overall structure, making it convenient to operate and particularly suitable for test scenarios requiring frequent height adjustments. The first clamp 21 includes an annular sleeve 211 and a fixing bolt. The annular sleeve 211 has an open end with a parallel mating part 212. The fixing bolt passes through the parallel mating part 212 and is used for fixation to ensure stable positioning during testing and prevent displacement due to vibration or impact. One side of the fixing plate 22 has an arc-shaped groove that matches the periphery of the first clamp 21. The fixing plate is welded to the groove. The first cylinder 311 or the second cylinder 312 is mounted on the fixed plate 22, which provides a planar reference for the first cylinder 311 or the second cylinder 312, ensuring the alignment of the cylinder piston axis with the gripper 32 and avoiding clamping force deviation due to tilting. The cylinder is bolted to the fixed plate 22 to distribute the reaction force during cylinder operation and reduce vibration. The first clamp 21 is compatible with various specifications of telescopic rods 11, improving the versatility of the device.

[0040] In some optional embodiments, the support frame 1 includes a support rod 12 and a limiting sleeve 13. The outer surface of the support rod 12 is provided with a threaded area in its own height direction, and the inner surface of the limiting sleeve 13 is provided with threads. The support rod 12 and the limiting sleeve 13 are threadedly connected, and the fixing component 2 is disposed on the limiting sleeve 13.

[0041] Specifically, the threaded area on the outer surface of the support rod 12 engages with the internal thread of the limiting sleeve 13, allowing for stepless and continuous height adjustment with millimeter-level precision by rotating the limiting sleeve 13. The fixing component 2 is directly installed on the limiting sleeve 13, forming an integral force-bearing frame that distributes the torque of the clamping component 3 and reduces the risk of bending of the support rod 12.

[0042] In some optional embodiments, the power component 31 includes a drive component 313 and a transmission component 314. The drive component 313 is disposed on the fixed component 2, and the gripper 32 is rotatably connected to the fixed component 2. The drive component 313 drives the gripper 32 to grip or release through the transmission component 314.

[0043] Specifically, the drive component 313 provides power, which is converted into the rotational motion of the gripper 32 via the transmission component 314, achieving high-precision angle control and ensuring the accuracy of clamping force and release timing. The gripper 32 is rotatably connected to the fixed component 2, and gripping or releasing is achieved through rotational opening and closing, resulting in smoother movements and avoiding the instantaneous impact that may occur with direct-push clamping by cylinders, thus protecting fragile or delicate adhesive tubes containing sealant. The drive component 313 is fixed to the fixed component 2 and does not need to move with the gripper 32, reducing the mass of moving parts and lowering inertial interference, making it particularly suitable for high-frequency drop tests.

[0044] In some optional embodiments, the gripper 32 includes a first clamping plate 323 and a second clamping plate 324. A first gear 325 and a second gear 326 are respectively connected to the fixed component 2 via a rotating shaft 231. The transmission component 314 is a gear transmission structure, and the driving component 313 is a cylinder. The cylinder drives the first clamping plate 323 and the second clamping plate 324 to grip or release through the gear transmission structure.

[0045] Specifically, the transmission component includes a first gear 325, a second gear 326, and a transmission gear rack 327. The driving component 313 is disposed on the fixed component 2 and is connected to the transmission gear rack 327. The first gear 325 and the second gear 326 respectively mesh with the transmission gear rack 327. The end of the first clamping plate 323 is connected to the first gear 325, and the end of the second clamping plate 324 is connected to the second gear.

[0046] Furthermore, both the first clamping plate 323 and the second clamping plate 324 include an arc-shaped plate and an extension plate. The end of the arc-shaped plate is connected to the extension plate, and the extension plate is rotatably connected to the fixing component. The arc-shaped plates of the first clamping plate 323 and the second clamping plate 324 are arranged face to face, and the two arc-shaped plates enclose a cylindrical body with an internal space. The curved surface design of the arc-shaped plates forms a flexible clamping mechanism, which can conform to cylindrical, spherical, or irregularly shaped grout tubes, increasing the contact area and reducing local stress damage. The driving component 313 drives the transmission gear rack 327 to move in a certain direction. During the movement, the transmission gear rack 327 drives the first gear 325 or the second gear 326 to rotate, thereby driving the first clamping plate 323 and the second clamping plate 324 to move clockwise or counterclockwise, thereby realizing the gripping and release of the first clamping plate 323 and the second clamping plate 324.

[0047] In some optional embodiments, the fixing component 2 includes a support plate 23, a limiting plate 24, a fixing rod 25, and a second clamp. The support plate 23 is arranged perpendicularly to the limiting plate 24. The limiting plate 24 is provided with a limiting hole 241. The fixing rod 25 is connected to the limiting plate 24 and the second clamp respectively. A gear transmission structure passes through the limiting hole 241. A cylinder is provided on the fixing rod 25. The support plate 23 is provided with a rotating shaft 231.

[0048] Specifically, the limiting plate 24 is used to support the transmission gear rack 327, which passes through the limiting hole 241. The limiting hole 241 provides guidance and limitation for the movement of the transmission gear rack 327, so that the transmission gear rack 327 can drive the first gear 325 and the second gear 326 to rotate more accurately, thereby driving the first clamping plate 323 and the second clamping plate 324 to move clockwise or counterclockwise, thereby realizing the gripping and release of the first clamping plate 323 and the second clamping plate 324.

[0049] Furthermore, the structure of the second clamp is the same as that of the first clamp described above. The second clamp includes an annular sleeve and a fixing bolt. The annular sleeve has an open end with parallel mating parts. The fixing bolt passes through the parallel mating parts and is used for fixation to ensure stable position during testing and avoid displacement due to vibration or impact.
