Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See Figures 1-5 , the utility model provides the following two technical solutions:

[0028] The first embodiment: an anti-pilling test device for polyester fabric production, comprising:

[0029] A placement plate 1 is provided with matching grooves 11 at the four corners of the upper surface of the placement plate 1. A mounting frame 12 is fixed in the middle of the placement plate 1. The mounting frame 12 is arranged in a "囧"-shaped structure, and a telescopic cylinder 13 is fixed in the middle of the upper surface of the mounting frame 12. Telescopic rods are fixed on both sides of the mounting frame 12.

[0030] The pressing plate 2 is fixed to the output end of the telescopic cylinder 13 on the mounting frame 12, and both sides of the upper surface of the pressing plate 2 are connected to the mounting frame 12 through telescopic rods. Positioning blocks 21 are fixed at the four corners of the lower surface of the pressing plate 2. The positioning blocks 21 are adapted to the matching grooves 11, and play a role of clamping and limiting the four corners of the fabric, so that the fabric can remain stable during testing and will not move at will. A motor 22 is fixed at one end of the upper surface of the pressing plate 2, and a turntable 24 is connected to the output end of the motor 22. A placement groove 23 is provided at one end of the lower surface of the pressing plate 2, and the turntable 24 is located in the placement groove 23. The motor 22 drives the turntable 24 to rotate. The turntable 24 is arranged in the placement groove 23 and will not be disturbed by external factors. The edge of the lower surface of the turntable 24 is movably connected with a connecting rod 25 through a pin shaft, and a dovetail slide groove 4626 is provided in the middle of the lower surface of the pressing plate 2.

[0031] The movable component 3 is arranged in the middle of the lower surface of the pressing plate 2 and is used to drive the test component 4 to move. The movable component 3 includes a movable plate 31 arranged in the middle of the lower surface of the pressing plate 2. A dovetail slider 4832 is fixed in the middle of the upper surface of the movable plate 31. The dovetail slider 4832 is located in the dovetail chute 4626, which plays a role in limiting and guiding, enabling the movable plate 31 to maintain linear movement and preventing the movable plate 31 from being separated from the texture of the pressing plate 2. A convex block 33 is fixed in the middle of one end of the movable plate 31. The convex block 33 is movably connected to one end of the connecting rod 25 through a pin shaft. The turntable 24 drives the movable plate 31 to reciprocate in the middle of the lower surface of the pressing plate 2 through the connecting rod 25 and the convex block 33. A connecting column 34 is fixed in the middle of the lower surface of the movable plate 31. Both sides of the top end of the connecting column 34 are fixed to the movable plate 31 through reinforcing plates 35, improving the compressive strength of the connecting column 34. A compression spring 36 is fixed to the bottom end of the connecting column 34. The bottom of the compression spring 36 is fixed to a connecting plate 37. The setting of the compression spring 36 can prevent the test component 4 from damaging the fabric. Bearing plates 38 are fixed to both sides of the upper surface of the connecting plate 37. The bearing plates 38 are arranged in an acute angle structure, and movable sleeves 39 are fixed to the upper ends of both bearing plates 38. The cooperation of the bearing plates 38 and the movable sleeves 39 enables the connecting plate 37 to move vertically up and down, and at the same time improves the anti-bending strength of the connecting plate 37. The movable sleeve 39 is sleeved on the outer side of the lower end of the connecting column 34. Guide grooves 310 are formed on both sides of the lower end of the connecting column 34. Guide blocks are fixed to both inner walls of the movable sleeve 39. The guide blocks are located in the guide grooves 310, which play a guiding role, enabling the movable sleeve 39 to move vertically up and down. A positioning groove 371 is formed in the middle of the lower surface of the connecting plate 37. A plurality of limiting grooves 372 are formed in the circumferential side of the connecting plate 37 and are distributed in an annular array.

[0032] The second implementation mode is mainly different from the first implementation mode in that: there is a testing component 4 which is arranged at the bottom of the movable component 3 and used for testing the anti-pilling property of the fabric. The testing component 4 includes a connecting block 41. A friction block 42 is fixed on the lower surface of the connecting block 41. The friction block 42 reciprocates on the fabric to play a testing role. A groove 43 is formed on the upper surface of the connecting block 41. The groove 43 is adapted to the connecting plate 37. A limiting block 44 is fixed in the middle of the bottom of the groove 43. The limiting block 44 is adapted to the positioning groove 371, which improves the connection stability of the connecting block 41. A plurality of through grooves 45 distributed in an annular array are formed on the side wall of the groove 43. Sliding grooves 46 are formed on the inner walls on both sides of the through groove 45. A limiting plate 47 passes through the through groove 45. One end of the limiting plate 47 is adapted to the limiting groove 372 to play a limiting role, so that the connecting plate 37 and the connecting block 41 are stably connected. Sliders 48 are fixed on both sides of the limiting plate 47. The sliders 48 are located in the sliding grooves 46. One end of the slider 48 is connected to the sliding groove 46 through a return spring 49. The arrangement of the return spring 49 enables the limiting plate 47 to automatically insert into the limiting groove 372. By moving the limiting plate 47 to separate the limiting plate 47 from the limiting groove 372, the connecting block 41 can be separated from the connecting plate 37, making it convenient to quickly disassemble and replace the friction block 42 after wear.

[0033] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0034] During operation, first place the fabric on the placing plate 1, and then start the telescopic cylinder 13. The telescopic cylinder 13 drives the pressing plate 2 to move downward until the positioning block 21 on the pressing plate 2 contacts the mating groove 11 on the placing plate 1, which plays a role in pressing and limiting the four corners of the fabric. At this time, the friction block 42 is in close contact with the fabric under the reaction force of the pressing spring 36. Then start the motor 22. The motor 22 drives the turntable 24 to rotate. The turntable 24 drives the movable plate 31 to reciprocate on the lower surface of the pressing plate 2 through the connecting rod 25, and then drives the friction block 42 to reciprocate on the fabric to test the fabric. After long-term use, the friction block 42 is worn. At this time, pull the limiting plate 47 outward until the limiting plate 47 is separated from the limiting groove 372. At this time, move the connecting block 41 downward to separate the connecting block 41 from the connecting plate 37, and then disassemble and replace the friction block 42. When replacing the friction block 42, connect the connecting block 41 to the connecting plate 37 from bottom to top, so that the limiting block 44 on the connecting block 41 is inserted into the positioning groove 371 on the connecting plate 37. At this time, the limiting plate 47 automatically inserts into the limiting groove 372 on the connecting plate 37 under the action of the return spring 49, stably connecting the connecting block 41 and the connecting plate 37, and then stably installing the friction block 42.
