Description

Technical Field

[0001] This application relates to the field of synthetic leather manufacturing, and in particular to a synthetic leather testing device. Background Technology

[0002] Currently, in the processing of synthetic leather, after the surface treatment process is completed, the surface quality of the synthetic leather needs to be tested to determine whether whitening has occurred due to poor processing. The current method of assessment is manual. In practice, workers hold the synthetic leather with both hands and press it onto the end of a simple cylinder. A raised area appears on the surface of the synthetic leather, and the worker checks whether the raised area shows any whitening.

[0003] Regarding the aforementioned technologies, there are still some shortcomings: after processing the synthetic leather, it needs to be placed on the workbench. However, since the quick clamps are fixed around the first through hole, it is very inconvenient to place the synthetic leather between the quick clamps. Care must be taken not to accidentally touch the quick clamps during the placement of the synthetic leather, and the synthetic leather must be laid flat, which is not convenient for the operator. Therefore, it needs to be improved. Utility Model Content

[0004] To facilitate the placement of synthetic leather during testing without accidentally touching the quick clamps, this application provides a synthetic leather testing device.

[0005] This application provides a synthetic leather testing device, which adopts the following technical solution: A synthetic leather testing device includes a workbench, a lifting cylinder is fixedly connected to the bottom of the workbench, a testing cylinder for lifting synthetic leather is connected to the piston rod of the lifting cylinder, and the testing cylinder passes through the workbench surface and moves up and down; A base plate is fixedly connected to a workbench and used to place synthetic leather. The base plate has a first through hole and is covered with a pressing plate for pressing synthetic leather. The pressing plate has a second through hole aligned with the first through hole. A quick clamp, fixedly connected to the base plate, is used to apply downward pressure to the pressure plate; The base assembly is located between the base plate and the quick clamp and is used to connect the quick clamp and the base plate; The base assembly includes: Fixed base: The two sides of the fixed base are respectively fixedly connected to the base plate and the quick clamp; Movable base: fixedly connected to the quick clamp, and slidably connected to the base plate; the movable base has a detection station and a feeding station; when the movable base is in the detection station, the quick clamp is distributed in a circumferential array along the first through hole; when the movable base is in the feeding station, the movable base and the quick clamp on the movable base are both located below the base plate.

[0006] By adopting the above technical solution, when it is necessary to place synthetic leather on the base plate, the movable base can be moved first. When the movable base is located at the feeding station, the movable base and the quick clamp on the movable base are located below the base plate. A notch appears around the quick clamp around the first through hole, which makes it convenient for the staff to place the synthetic leather between the base plate and the pressure plate.

[0007] Optionally, the base plate has a movable cavity on the side near the movable base, and a sliding rail is fixedly connected in the movable cavity. A sliding block is integrally formed on the movable base and is inserted into and slides in the sliding rail. When the sliding block contacts the bottom of the sliding rail on the side away from the movable cavity, the movable base is in the feeding position.

[0008] By adopting the above technical solution, the sliding block slides only along the open direction of the sliding rail, which limits the movement angle of the movable base, so that the movable base can always maintain the same distance from other fixed bases, and ensure that the force of each quick clamp is the same when pressing the synthetic leather.

[0009] Optionally, the sliding block is made of iron, and the bottom of the sliding rail located in the movable cavity is fixedly connected to a magnetic component.

[0010] By adopting the above technical solution, when it is necessary to initially limit the movement of the movable base, the sliding block and the magnetic component can be magnetically connected to achieve initial fixation, so as to facilitate further fixation of the movable base in the future.

[0011] Optionally, both sides of the movable base are provided with locking components for fixing the movable base to the testing station. The locking component includes: The locking block can pass through the base plate into the movable base and move up and down between the base plate and the movable base. The lifting block is rotatably connected to the locking block and moves up and down within the movable base. When the lifting block can rotate freely on the movable base, the locking block disengages from the bottom plate and enters the movable base.

[0012] By adopting the above technical solution, when it is necessary to fix the movable base at the testing station, the operator inserts the locking block into the base plate and the lifting block into the movable base. The locking component limits the movable base, and when the quick clamp is in operation, the quick clamp located around the first through hole keeps the fixed position and does not vibrate.

[0013] Optionally, a rubber layer is fixedly bonded to the movable base, the rubber layer extends beyond the end face of the movable base and the surface of the rubber layer is provided with multiple anti-slip textures, and the lifting block can contact the rubber layer.

[0014] By adopting the above technical solution, the contact between the rubber layer and the locking block increases the friction between the locking block and the movable base, thereby improving the positional stability of the lifting block.

[0015] Optionally, the movable base is provided with a sliding groove for the lifting block to slide, and the opening of the sliding groove is chamfered, with the chamfer located in the direction of the sliding groove toward the rubber layer.

[0016] By adopting the above technical solution, even if the lifting block is not completely aligned with the sliding groove, the chamfered design can guide the block to slide into the sliding groove.

[0017] Optionally, a spring is wound around one end of the sliding rail near the worktable.

[0018] By adopting the above technical solution, the spring can slow down the movement speed of the movable base, thereby protecting the movable base and the quick clamp located on the movable base.

[0019] 1. In summary, the beneficial technical effect of this application is that workers can conveniently place synthetic leather by moving one or more movable bases. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0027] This application discloses a synthetic leather testing device. (Refer to...) Figure 1 , Figure 2 A synthetic leather testing device includes a workbench 1 and a base plate 2. The base plate 2 is mounted on the workbench 1, and support pillars for lifting the base plate 2 are integrally formed at each of its four corners. A first through hole 3 is formed at the center of the base plate 2. A lifting cylinder is fixedly connected to the bottom of the workbench 1 at the first through hole 3, and a testing cylinder for testing synthetic leather is attached to the end of the lifting cylinder. The testing cylinder can pass through the surface of the workbench 1 and move up and down. A pressure plate 5 is also covered on the base plate 2, with the synthetic leather located below the base plate 2 and below the pressure plate 5. A second through hole 4, corresponding to the first through hole 3, is formed at the center of the pressure plate 5. When the synthetic leather testing device is in operation, the first through hole 3 and the second through hole 4 are aligned.

[0028] Four quick-release clips 6 are also installed on the base plate 2. These clips are arranged in a circumferential array around the first through hole 3, with equal spacing between each clip. During synthetic leather testing, the quick-release clips 6 apply downward pressure to the pressure plate 5, thus securing the synthetic leather. The operator then controls a lifting cylinder to drive the testing cylinder upwards, allowing it to complete a defined stroke. The top of the testing cylinder passes through the first through hole 3 and pushes a protrusion onto the synthetic leather, enabling the operator to observe for any whitening phenomena and thus determine the quality of the synthetic leather.

[0029] Reference Figure 1 , Figure 2 A base assembly 7 is also provided between the base plate 2 and the quick clamp 6. The base assembly 7 includes a fixed base 8 fixedly connected to the base plate 2 and a movable base 9 movably connected to the base plate 2. In this embodiment, a total of three fixed bases 8 and one movable base 9 are provided. The quick clamp 6 is located on the fixed base 8 or the movable base 9 and is fixedly connected to either the fixed base 8 or the movable base 9.

[0030] When synthetic leather needs to be placed on the base plate 2, the operator can first move the movable base 9 to the feeding position. At this time, the movable base 9 will move the quick-release clamp 6 located on it towards the worktable 1 and detach from the base plate 2. When the movable base 9 enters the feeding position, both the movable base 9 and the quick-release clamp 6 are located below the base plate 2. The operator can then conveniently place the synthetic leather on the base plate 2.

[0031] Afterwards, the operator can continue to operate the movable base 9, moving it from the feeding station to the inspection station. At this time, the quick clamps 6 located on the movable base 9 and the fixed base 8 will form a circumferential array around the first through hole 3, and press and fix the synthetic leather through the quick clamps 6 located around the pressure plate 5, allowing the lifting cylinder to lift the synthetic leather for inspection. Locking components 14 are also provided on both sides of the movable base 9, which can fix the movable base 9 to the inspection station.

[0032] Reference Figure 1 , Figure 2 A movable cavity 10 is also provided on the base plate 2. The number of movable cavities 10 is the same as the number of movable bases 9, and the movable cavities 10 are located at the bottom of the corresponding movable bases 9. A sliding rail 11 is fixedly connected inside the movable cavity 10. One end of the sliding rail 11 is fixedly connected to the bottom of the movable cavity 10, and the other end of the sliding rail 11 extends out of the movable cavity 10 and is fixedly connected to the table surface of the workbench 1. A sliding block 12 is integrally formed on the movable base 9 located above the movable cavity 10. The sliding block 12 is inserted into the sliding rail 11 and can slide along the shape of the sliding rail 11. When the movable base 9 is in the feeding position, the vertical height of the movable base 9 and the quick clamp 6 on the movable base 9 is lower than that of the base plate 2. By lowering the height of the movable base 9 and the quick clamp 6 in one direction, it is convenient for the operator to place the synthetic leather onto the base plate 2.

[0033] A spring 21 is also provided at one end of the slide rail 11 near the worktable 1, and the spring 21 is wound around the slide rail 11. When the movable base 9 enters the feeding station, if the operator operates it improperly and causes the movable base 9 to slide on the slide rail 11 at a relatively high speed, the movable base 9 will collide with the worktable 1 with a large impact force, thereby causing damage to the movable base 9 and the quick clamp 6. The spring 21 can slow down the movement speed of the movable base 9, thereby protecting the movable base 9 and the quick clamp 6 located on the movable base 9.

[0034] Reference Figure 3 , Figure 4The locking assembly 14 includes a locking block 15 and a lifting block 16. A locking groove 19 and a sliding groove 18 aligned with the locking groove 19 are provided on the base plate 2. The locking block 15 can slide within the locking groove 19 and enter the sliding groove 18, while the lifting block 16 slides within the sliding groove 18. A rotating rod is provided between the locking block 15 and the lifting block 16, enabling a rotatable connection between them.

[0035] When the worker moves the movable base 9 from the inspection station to the feeding station, he can hold the lifting block 16 and pull it. When the worker exerts force on the lifting block 16, the lifting block 16 and the locking block 15 will move simultaneously away from the worktable 1 until the locking block 15 is completely disengaged from the locking groove 19. At this time, the worker can rotate the lifting block 16 to make it move away from the opening of the sliding groove 18 and be misaligned with the sliding groove 18.

[0036] Reference Figure 3 , Figure 4 A rubber layer 17 is also fixedly bonded to the movable base 9. The number of rubber layers 17 is the same as the number of lifting blocks 16. Multiple anti-slip patterns are linearly arrayed on the outer surface of the rubber layer 17, and the end face of the rubber layer 17 with anti-slip patterns extends beyond the end face of the movable base 9 and can contact the lifting block 16. After the lifting block 16 rotates out of the sliding groove 18, the operator can transfer the lifting block 16 onto the rubber layer 17. The rubber layer 17 increases the friction between the lifting block 16 and the movable base 9, thereby fixing the lifting block 16 relatively and preventing the locking block 15 from falling into the locking groove 19 when the sliding block slides in the sliding cavity.

[0037] Reference Figure 4 , Figure 5 When synthetic leather needs to be tested, the worker moves the movable base 9 from the feeding station to the testing station. Since the sliding block 12 is made of iron, and a magnetic component 13 is fixedly connected to the bottom of the sliding rail 11 located in the movable cavity 10, the movable base 9 will be in close contact with the magnetic component 13 when it moves to the testing station. The magnetic attraction of the magnetic component 13 will initially fix the movable base 9. At this time, the sliding cavity and the locking groove 19 are just aligned. The worker then rotates the lifting block 16, causing the lifting block 16 to detach from the rubber layer 17 and move above the locking groove 19. At this time, the locking block 15 and the lifting block 16 will move towards the worktable 1 due to gravity. The locking block 15 falls into the locking groove 19, and part of the lifting block 16 falls into the sliding cavity.

[0038] Reference Figure 4 , Figure 5A chamfer 20 is provided at the opening of the sliding groove 18, and the chamfer 20 is located in the direction of the sliding groove 18 toward the rubber layer 17. Even if the lifting block 16 is not completely aligned with the sliding groove 18, the chamfer 20 can guide the block to slide into the sliding groove 18.

[0039] The implementation principle of a synthetic leather testing device disclosed in this application embodiment is as follows: When the worker needs to place the synthetic leather on the base plate 2, the lifting block 16 can be pulled to disengage the locking block 15 from the locking groove 19. Then, the movable base 9 and the quick clamp 6 located on the movable base 9 can be moved below the base plate 2 to facilitate the placement of the synthetic leather. If it is necessary to test the synthetic leather, the movable base 9 can be moved to the testing station and the locking block 15 can be inserted into the locking groove 19 to fix the position of the movable base 9.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
