Description

Technical Field

[0001] This application relates to the field of plastic packaging bag testing technology, and in particular to a toughness and strength testing device. Background Technology

[0002] Plastic packaging bags are bags made primarily of plastic. They are essential items in people's daily lives and are often used to pack other items. They are widely used because of their low price, light weight, large capacity, and ease of storage. Plastic bags are mass-produced in factories. To ensure product quality, the produced plastic bags need to undergo toughness and strength testing before leaving the factory.

[0003] Chinese Patent No. CN214952728U discloses a device for testing the toughness and strength of plastic bags. Preferably, the transmission mechanism includes a motor, a threaded rod, a threaded block, and a movable plate. The output end of the motor is fixedly connected to the threaded rod, the outer side of the threaded rod is fixedly connected to the threaded block, and the top of the threaded block is fixedly connected to the movable plate. One side of the movable plate is welded to one end of a first spring. The bottom of the motor is fixedly connected to the top of the operating table. By rotating the fixing bolt in the fixing mechanism, the pressure plate is moved to cooperate with the fixing plate to fix the plastic bag to be measured. Then, one end of the plastic bag is fixed to the hook. The motor in the transmission mechanism drives the threaded rod and other parts to move the hook, thereby completing the toughness test of the plastic bag.

[0004] However, the aforementioned patent requires manual pressing of the plastic packaging bag to fix it by using a fixing bolt to drive the pressure plate. When fixing multiple plastic packaging bags for testing, the fixing process is cumbersome, increasing the labor intensity of the testing personnel. Furthermore, the device can only test a single plastic packaging bag using a single hook. After testing, the bag must be removed before another plastic packaging bag can be placed. Therefore, it is difficult to continuously test plastic packaging bags, reducing the testing speed. To solve the above problems, we provide a toughness strength testing device. Utility Model Content

[0005] The purpose of this invention is to provide a toughness and strength testing device to solve the problem mentioned in the background art that the current method of testing the toughness and strength of plastic packaging bags requires manual pressing and fixing of the plastic packaging bag by driving the pressure plate through the fixing bolt. The fixing process is cumbersome, and the device can only test the plastic packaging bag through a single hook. After the test, it needs to be removed before another plastic packaging bag can be placed. Therefore, it is difficult to continuously test plastic packaging bags, which reduces the testing speed.

[0006] The embodiments of this application adopt the following technical solutions: A toughness and strength testing device includes a support plate, a transmission seat fixedly connected to one side of the support plate, a scale fixedly connected to one side of the transmission seat, a rotating disk above the support plate, a ring of hooks fixedly connected to the upper surface of the rotating disk, a reduction motor below the support plate, a rotating shaft fixedly mounted at the output end of the reduction motor, the top end of the rotating shaft fixedly mounted to the bottom surface of the rotating disk, an electric cylinder fixedly mounted on the inner wall of the transmission seat, a connecting plate fixedly mounted at the telescopic end of the electric cylinder, a transmission cover fixedly mounted on one side of the connecting plate, a connecting block fixedly connected to the upper surface of the transmission cover, a platform fixedly mounted on the upper surface of the connecting block, and a clamping assembly fixedly mounted on one side of the platform.

[0007] Preferably, the clamping assembly includes a fixed support plate fixedly mounted on one side of the platform, a rectangular slide plate fixedly connected to one side of the fixed support plate, a threaded transmission block slidably connected to the inner wall of the rectangular slide plate, a fixed seat fixedly mounted on the upper surface of the rectangular slide plate, a micro motor fixedly mounted on one side of the fixed seat, a threaded transmission rod fixedly mounted on the output end of the micro motor, the outer surface of the threaded transmission rod being threadedly connected to the inner wall of the threaded transmission block, a bearing seat fixedly mounted on one side of the fixed seat, the inner ring of the bearing seat being fixedly connected to the outer surface of the threaded transmission rod, a pressure clamping plate fixedly connected to the bottom surface of the threaded transmission block, and a silicone anti-slip pad fixedly connected to the bottom surface of the pressure clamping plate.

[0008] Preferably, a scale indicator bar is fixedly connected to one side of the platform, the scale indicator bar is located on one side of the scale ruler, a sliding hole is opened on the upper surface of the transmission seat, and the outer surface of the connecting block is slidably connected to the inner wall of the sliding hole.

[0009] Preferably, a bearing ring is fixedly embedded in the bottom surface of the support plate, and the outer surface of the rotating shaft is fixedly connected to the inner ring of the bearing ring.

[0010] Preferably, the bottom surface of the support plate is fixedly connected to two fixing plates, and the side of the two fixing plates that are close to each other is fixedly connected to the outer surface of the geared motor.

[0011] Preferably, the bottom surface of the support plate is fixedly connected to two sets of support feet, and the bottom surface of the transmission seat is fixedly connected to a support base.

[0012] The above-described technical solutions adopted in the embodiments of this application can achieve the following beneficial effects: 1. This toughness and strength testing device involves placing the fixed end of a plastic packaging bag on a platform, activating a micro motor, and using the cooperation of a threaded transmission rod and a threaded transmission block to drive a pressure clamp to automatically press down and fix the fixed end of the plastic packaging bag. A silicone anti-slip pad ensures the stability of the fixation. Furthermore, this clamping assembly eliminates the need for repeated manual tightening of the fixing bolts, avoiding frequent manual operation and reducing the labor intensity of testing personnel.

[0013] 2. This toughness and strength testing device, through the cooperation of a rotating disk and multiple hooks, allows the electric cylinder to push the platform to apply tension after the first sample is suspended by the hook. The scale indicator bar and scale ruler work together to complete the test. After the test is completed, the rotating disk is driven by a geared motor, which allows the tested sample to be removed with the hook. At the same time, the new sample suspended by the idle hook can be rotated and aligned, and the new sample can be immediately fixed by the clamping assembly. The whole process does not require waiting to remove the tested sample, which improves the toughness and strength testing efficiency of plastic packaging bags and solves the problem of test interruption in traditional devices.

[0016] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0017] Example 1 As attached Figure 1 , Figure 2 and Figure 4 The toughness and strength testing device shown includes a support plate 1, a transmission seat 2 fixedly connected to one side of the support plate 1, a scale 17 fixedly connected to one side of the transmission seat 2, a rotating disk 3 above the support plate 1, a ring of hooks 7 fixedly connected to the upper surface of the rotating disk 3, the hooks 7 having a protective layer to prevent damage to plastic packaging bags, a reduction motor 4 below the support plate 1, a rotating shaft 6 fixedly installed at the output end of the reduction motor 4, the top end of the rotating shaft 6 fixedly installed to the bottom surface of the rotating disk 3, an electric cylinder 8 fixedly installed on the inner wall of the transmission seat 2, a connecting plate 9 fixedly installed at the telescopic end of the electric cylinder 8, a transmission cover 10 fixedly installed on one side of the connecting plate 9, a connecting block 11 fixedly connected to the upper surface of the transmission cover 10, a platform 5 fixedly installed on the upper surface of the connecting block 11, and a clamping assembly 13 fixedly installed on one side of the platform 5.

[0018] As can be seen from the above description, this utility model has the following beneficial effects: through the cooperation of the rotating disk 3 and multiple hooks 7, after the first sample is suspended by the hook 7, the electric cylinder 8 pushes the platform 5 to apply tension, and the scale indicator 18 and the scale ruler 17 cooperate to complete the test. After the test is completed, the rotating disk 3 is driven to rotate by the reduction motor 4, which can make the tested sample move away with the hook 7. At the same time, the new sample suspended by the idle hook 7 can be rotated and aligned, and the new sample can be immediately fixed by the clamping assembly 13. The whole process does not require waiting to remove the tested sample, thus improving the testing efficiency of the toughness and strength of plastic packaging bags.

[0019] Example 2 Based on Embodiment 1, the solution in Embodiment 1 will be further described in detail below, with reference to the specific working method described in detail: like Figure 4 and Figure 5As shown, in a preferred embodiment, the clamping assembly 13 includes a fixed support plate 131 fixedly mounted on one side of the platform 5. A rectangular slide plate 132 is fixedly connected to one side of the fixed support plate 131. A threaded transmission block 136 is slidably connected to the inner wall of the rectangular slide plate 132. A fixed seat 133 is fixedly mounted on the upper surface of the rectangular slide plate 132. A micro motor 134 is fixedly mounted on one side of the fixed seat 133. A threaded transmission rod 135 is fixedly mounted on the output end of the micro motor 134. The outer surface of the threaded transmission rod 135 is threadedly connected to the inner wall of the threaded transmission block 136. A bearing seat 137 is fixedly mounted on one side of the fixed seat 133. The inner surface of the bearing seat 137... The outer surface of the ring is fixedly connected to the threaded transmission rod 135. The bottom surface of the threaded transmission block 136 is fixedly connected to the pressure clamp 138. The bottom surface of the pressure clamp 138 is fixedly connected to the silicone anti-slip pad 139. Furthermore, the rectangular slide plate 132 enables it to slide only in the vertical direction, ensuring that the pressure clamp 138 is aligned with the plastic packaging bag. The fixing seat 133 provides an installation reference for the micro motor 134 and the bearing seat 137. The bearing seat 137 reduces the frictional resistance when the threaded transmission rod 135 rotates. The silicone anti-slip pad 139 increases the friction between the pressure clamp 138 and the plastic packaging bag, preventing the packaging bag from slipping during testing and improving the reliability of fixing and the accuracy of testing.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, in a preferred embodiment, a scale indicator strip 18 is fixedly connected to one side of the platform 5, the scale indicator strip 18 is located on one side of the scale 17, a sliding hole 12 is provided on the upper surface of the transmission seat 2, the outer surface of the connecting block 11 is slidably connected to the inner wall of the sliding hole 12, a bearing ring 14 is fixedly embedded in the bottom surface of the support plate 1, the outer surface of the rotating shaft 6 is fixedly connected to the inner ring of the bearing ring 14, two fixing plates 15 are fixedly connected to the bottom surface of the support plate 1, and the sides of the two fixing plates 15 that are close to each other are fixedly connected to the outer surface of the reduction motor 4. Two sets of support feet 16 are fixedly connected to the bottom surface, and a support base 19 is fixedly connected to the bottom surface of the transmission seat 2. Furthermore, through the cooperation of the scale indicator strip 18 and the scale ruler 17, the moving distance of the platform 5 can be displayed intuitively, which can provide a basis for toughness and strength testing. The sliding hole 12 plays a guiding and limiting role for the connecting block 11, ensuring that the platform 5 moves in a straight line with the extension and retraction of the electric cylinder 8. The bearing ring 14 ensures that the rotating disk 3 rotates smoothly. The fixing plate 15 firmly fixes the reduction motor 4 to the bottom surface of the support plate 1 to prevent the vibration generated by the motor from being transmitted to other components during operation.

[0021] The working process of this utility model is as follows: When using this toughness and strength testing device, first place the fixed end of the plastic packaging bag on the surface of the platform 5, then start the micro motor 134 in the clamping assembly 13. The output end of the micro motor 134 drives the threaded transmission rod 135 to rotate. Because the surface of the threaded transmission rod 135 is threadedly connected to the inner wall of the threaded transmission block 136, the threaded transmission block 136 can move vertically downward along the rectangular slide plate 132, and will drive the silicone anti-slip pad 139 on the bottom surface of the pressure clamp 138 to fit tightly with the plastic packaging bag, thus completing the automatic fixing.

[0022] After fixing, the other end of the plastic packaging bag is hung on the hook 7 of the rotating disk 3. Then, the electric cylinder 8 is started, pushing the connecting plate 9 to drive the transmission cover 10 and the connecting block 11 to slide along the sliding hole 12. The platform 5 moves synchronously, and the scale indicator 18 moves with the platform 5, which can apply tensile force to the plastic packaging bag to test its toughness. The movement distance can be observed by comparing with the scale 17. After the first plastic packaging bag is tested, the reduction motor 4 drives the rotating disk 3 to continue rotating, which can make the tested packaging bag leave the test position with the hook 7. At the same time, the next idle hook 7 rotates to the corresponding position. At this time, the new plastic packaging bag can be fixed by the clamping component 13. There is no need to wait to remove the tested sample, so continuous testing can be achieved. This is the working process and working principle of the device.
