Description

Technical Field

[0001] This utility model relates to the field of testing equipment, specifically a strength testing device for bag fabric production. Background Technology

[0002] Bags and luggage are a general term for all kinds of bags used to carry things, including general shopping bags, handbags, clutches, wallets, backpacks, shoulder bags, shoulder bags, waist bags, and various types of rolling suitcases.

[0003] When using bag fabrics, it is necessary to test their strength to prevent insufficient strength from greatly reducing the lifespan of the bags. During long-term use, the weight of the contents inside the bags will cause the fabric to gradually stretch, resulting in severe deformation of the bags. Therefore, the quality of the fabric's stretchability is also extremely important. Thus, there is an urgent need for a device that can test the stretchability of the fabric to solve the above problems and ensure the quality of bags. Utility Model Content

[0004] The purpose of this invention is to provide a strength testing device for bag fabric production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a strength testing device for bag fabric production, comprising a support frame and a spring. An electric push rod is fixedly mounted at the top of the support frame, and a hollow rod is fixedly mounted at the lower end of the electric push rod. A movable rod is slidably mounted inside the hollow rod, and a fixed plate is fixedly mounted at the lower end of the movable rod. The spring is fixed between the fixed plate and the lower end face of the top of the hollow rod. A first fixing mechanism for convenient fabric fixing is provided at the lower end of the fixed plate, and a second fixing mechanism for convenient fabric fixing is provided at the bottom of the support frame. A measuring mechanism for convenient measurement of tensile length is provided on one side of the first fixing mechanism. The first fixing mechanism includes a first U-shaped block, a first fixing tooth, a first screw, and a first clamping plate. The first U-shaped block is fixed at the lower end of the fixed plate. The first screw is threaded through and mounted on one side of the first U-shaped block. The first clamping plate is movably embedded in one side of the first screw. Several first fixing teeth are provided and fixed inside the first clamping plate and the first U-shaped block.

[0006] Preferably, the second fixing mechanism includes a second U-shaped block, a second clamping plate, a second screw, and a second fixing tooth. The second U-shaped block is fixed to the bottom of the support frame. The second clamping plate is slidably disposed inside the second U-shaped block. The second screw is threaded through one side of the second U-shaped block, and one side of the second screw is movably embedded in one side of the second clamping plate. Several second fixing teeth are provided and fixed to one side of the second U-shaped block and the second clamping plate. In use, the upper and lower sides of the fabric are respectively placed between the first U-shaped block and the second U-shaped block. Then, the first screw is rotated, and the first screw drives the first clamping plate to move along the inside of the first U-shaped block until the first fixing tooth clamps and fixes the upper end of the fabric. Then, the fabric is tightened. Then, the second screw is rotated, so that the second clamping plate moves along the inside of the second U-shaped block until the second fixing tooth clamps and fixes the lower end of the fabric. Then, the electric push rod is activated, which drives the hollow rod to move upward, so that the spring is stretched, and the elastic force keeps the fabric in a taut state.

[0007] Preferably, the measuring mechanism includes a marking ruler and a marking rod. The marking rod is fixed to one side of the first U-shaped block, and the marking ruler is fixed to the bottom of the inner side of the support frame. During use, after the fabric is stretched, the position of the marking rod on one side of the marking ruler is recorded. After stretching for a period of time, the position of the subsequent marking rod on one side of the marking ruler is observed, and the stretching amount is calculated. This determines the stretching quality of the fabric, ensuring the stretching quality of the fabric and preventing excessive deformation of the bag caused by excessive fabric deformation during subsequent use.

[0008] Preferably, the top of the first clamping plate is tightly attached to the top of the inside of the first U-shaped block.

[0009] Preferably, the lower end of the second clamping plate is tightly attached to the lower end of the inside of the second U-shaped block.

[0010] Preferably, the marking rod is located on one side of the marking ruler and is close to the outside of the marking ruler.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. In use, the fabric is placed between the first U-shaped block and the second U-shaped block on the upper and lower sides respectively. Then, the first screw is rotated, which drives the first clamping plate to move along the inside of the first U-shaped block until the first fixing tooth clamps and fixes the upper end of the fabric. Then the fabric is stretched. Then the second screw is rotated, which causes the second clamping plate to move along the inside of the second U-shaped block until the second fixing tooth clamps and fixes the lower end of the fabric. Then the electric push rod is activated, which drives the hollow rod to move upward, so that the spring is stretched and the elasticity keeps the fabric in a taut state.

[0013] 2. When using this utility model, after the fabric is stretched, the position of the recording rod on one side of the marking ruler is recorded. After stretching for a period of time, the position of the subsequent recording rod on one side of the marking ruler is observed, and the stretching amount is calculated. This determines the stretching quality of the fabric, ensuring the stretching quality of the fabric and preventing excessive deformation of the bag caused by excessive fabric deformation during subsequent use.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4This utility model provides a strength testing device for bag fabric production, including a support frame 1 and a spring 7. An electric push rod 2 is bolted to the top of the support frame 1, and a hollow rod 5 is bolted to the lower end of the electric push rod 2. A movable rod 6 slides inside the hollow rod 5, and a fixing plate 9 is bolted to the lower end of the movable rod 6. The spring 7 is welded and fixed between the fixing plate 9 and the lower end face of the top of the hollow rod 5. The lower end of the fixing plate 9 has a first fixing mechanism for conveniently fixing the fabric, and the bottom of the support frame 1 has a second fixing mechanism for conveniently fixing the fabric. The mechanism has a measuring mechanism on one side for convenient measurement of tensile length. The first fixing mechanism includes a first U-shaped block 8, a first fixing tooth 10, a first screw 12 and a first clamping plate 11. The first U-shaped block 8 is fixed to the lower end of the fixing plate 9 by bolts. The first screw 12 is threaded through one side of the first U-shaped block 8. The first clamping plate 11 is movably embedded in one side of the first screw 12. The top of the first clamping plate 11 is tightly attached to the inner top of the first U-shaped block 8. There are several first fixing teeth 10, which are welded and fixed to the inner side of the first clamping plate 11 and the first U-shaped block 8.

[0021] The second fixing mechanism includes a second U-shaped block 14, a second clamping plate 16, a second screw 15, and second fixing teeth 13. The second U-shaped block 14 is fixed to the bottom of the support frame 1 by bolts. The second clamping plate 16 slides inside the second U-shaped block 14. The second screw 15 is threaded through one side of the second U-shaped block 14, and one side of the second screw 15 is movably embedded in one side of the second clamping plate 16. The lower end of the second clamping plate 16 is tightly attached to the lower end of the interior of the second U-shaped block 14. Several second fixing teeth 13 are welded and fixed to one side of the second U-shaped block 14 and the second clamping plate 16. During use... The fabric is positioned between the first U-shaped block 8 and the second U-shaped block 16 on its upper and lower sides, respectively. Then, the first screw 12 is rotated, which drives the first clamping plate 11 to move along the inside of the first U-shaped block 8 until the first fixing tooth 10 clamps and fixes the upper end of the fabric. The fabric is then stretched. Next, the second screw 15 is rotated, which causes the second clamping plate 16 to move along the inside of the second U-shaped block 14 until the second fixing tooth 13 clamps and fixes the lower end of the fabric. Then, the electric push rod 2 is activated, which drives the hollow rod 5 to move upward, causing the spring 7 to be stretched. At the same time, the elasticity keeps the fabric in a taut state.

[0022] The measuring mechanism includes a marking ruler 3 and a marking rod 4. The marking rod 4 is welded and fixed to one side of the first U-shaped block 8. The marking ruler 3 is welded and fixed to the bottom of the inner side of the support frame 1. The marking rod 4 is located on one side of the marking ruler 3 and is close to the outside of the marking ruler 3. When the fabric is stretched during use, the position of the marking rod 4 on one side of the marking ruler 3 is recorded. After stretching for a period of time, the position of the marking rod 4 on one side of the marking ruler 3 is observed, and the stretching amount is calculated. This determines the stretching quality of the fabric and ensures the stretching quality of the fabric, thereby preventing excessive deformation of the bag caused by excessive fabric deformation during subsequent use.

[0023] Working principle: During use, the fabric is placed between the first U-shaped block 8 and the second U-shaped block 16 on the top and bottom sides respectively. Then, the first screw 12 is rotated, which drives the first clamping plate 11 to move along the inside of the first U-shaped block 8 until the first fixing tooth 10 clamps and fixes the upper end of the fabric. After that, the fabric is stretched. Then, the second screw 15 is rotated, which causes the second clamping plate 16 to move along the inside of the second U-shaped block 14 until the second fixing tooth 13 clamps and fixes the lower end of the fabric. Then, the electric push rod 2 is activated, which drives the hollow rod 5 to move upward, so that the spring 7 is stretched. At the same time, the elasticity keeps the fabric in a taut state. During use, after the fabric is stretched, the position of the marker rod 4 on the side of the marker ruler 3 is recorded. After stretching for a period of time, the position of the marker rod 4 on the side of the marker ruler 3 is observed, and the stretching amount is calculated. This determines the stretching quality of the fabric and ensures the stretching quality of the fabric, thereby preventing the problem of excessive deformation of the bag caused by excessive fabric deformation during subsequent use.
