Description

Technical Field

[0001] This utility model relates to the field of material cutting technology, and in particular to a ring compression specimen cutting knife. Background Technology

[0002] In packaging materials, paper, and many other industries based on fiber materials, ring crush strength is a crucial performance indicator that plays a vital role in evaluating material quality and suitability. Ring crush strength directly reflects a material's resistance to ring pressure. For packaging materials, this characteristic is crucial for effectively protecting the contents and ensuring the integrity of the packaging during transportation and storage; for paper materials, it affects their performance in printing, writing, and other applications. To accurately and scientifically measure ring crush strength, a large number of precisely sized ring crush test specimens that fully meet quality standards must be prepared. Therefore, a ring crush test specimen cutting tool needs to be designed.

[0003] The existing ring crush test specimen cutting blades lack material pretreatment structures. Untreated materials are directly fed into the cutting process, which greatly affects the cutting quality. This makes it difficult for the final ring crush test specimens to meet the testing standards, seriously reducing the integrity of the overall processing technology and product quality. Furthermore, the specimen collection relies heavily on manual collection of the cut specimens, which reduces the continuity and efficiency of the cutting work. Utility Model Content

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example 1: Please refer to Figures 1 to 9 : This utility model proposes a ring crushing specimen cutting knife, including: a base plate 1; Two sets of support plates 11 are bolted to the lower end of the base plate 1. A material trough 12 is provided on the base plate 1. Two sets of mounting plates 3 are bolted to the lower end of the base plate 1. Each set of mounting plates 3 is provided with a slide rail. A receiving plate 31 slides on the slide rail. Two sets of linkage plates 311 are bolted to the front and rear ends of the receiving plate 31. A first motor 32 is bolted to each set of mounting plates 3. A pulley is installed on the output shaft of the first motor 32. A support 33 is installed on the mounting plate 3. A pulley is installed on the support 33 through a bearing. A transmission belt 321 connects the pulley on the output shaft of the first motor 32 and the pulley on the support 33. The linkage plate 311 is fixedly connected to the transmission belt 321. The receiving plate 31 is located directly below the material trough 12.

[0021] In this embodiment of the disclosure, Two sets of support screws 13 are fixed on the base plate 1. A top plate 14 is installed on the upper end of the two sets of support screws 13, and the top plate 14 is locked to the two sets of support screws 13 by nuts. A bottom cylinder 131 and a top cylinder 132 are installed on each set of support screws 13. The diameter of the top cylinder 132 is larger than the diameter of the bottom cylinder 131. A spring 133 is installed between the bottom cylinder 131 and the top cylinder 132. The spring 133 is sleeved on the support screws 13. A movable plate 16 is installed between the top cylinder 132 and the top plate 14. A pressure rod 15 is mounted on the 14 via a pin. A pressure handle 151 is fixed to the pressure rod 15. Two sets of connecting plates 161 connect the pressure rod 15 and the movable plate 16. A round rod 162 is fixed between the two sets of connecting plates 161. The pressure rod 15 presses down on the round rod 162. Two sets of through holes are provided on the movable plate 16. A lower pressure plate 163 is installed at the lower end of the movable plate 16 via bolts. A rectangular through groove is provided on the lower pressure plate 163. A cutting blade 165 is fixed at the lower end of the movable plate 16. The cutting blade 165 is located at... Two sets of buffer rods 164 are fixed in the rectangular through slot on the lower pressure plate 163 and on the top plate 14. The two sets of buffer rods 164 are respectively located in two sets of through holes on the movable plate 16. Two sets of support plates 17 are bolted to the bottom plate 1. Two sets of spacers 171 are bolted between the two sets of support plates 17. The through slots between the support plates 17 and the spacers 171 are respectively connected to the material discharge chute 12 and the rectangular through slot on the lower pressure plate 163. Their function is: when the operator presses down the pressure handle 151, the pressure rod 15... Rotating around the pivot, pressure is transmitted to the movable plate 16 through the connecting plate 161 and the round rod 162, driving the movable plate 16 to move downward, which in turn drives the cutting blade 165 installed at its lower end to perform a cutting operation. The bottom cylinder 131, top cylinder 132 and the spring 133 between them installed on the support screw 13 constitute an elastic buffer system. During the cutting process, when pressure is applied to make the movable plate 16 drive the cutting blade 165 to move downward, the spring 133 will generate elastic deformation to provide buffering force.

[0022] Example 2, based on Example 1, A side frame 2 is fixed on the left side of the base plate 1. Two sets of idlers 21 are mounted on the side frame 2 via bearings. A connecting plate 22 is also fixed on the side frame 2. The connecting plate 22 is at the same height as the pallet 17. Its function is that the connecting plate 22 fixed on the side frame 2, and its height being the same as the pallet 17, allows the material conveyed from the idlers 21 to be smoothly transferred to the pallet 17, ensuring the continuity and stability of the material in the entire conveying and cutting process.

[0023] Example 3, based on Examples 1 and 2, Four sets of motor mounts 23 are bolted to the side frame 2. A second motor 231 is bolted to each motor mount 23. Four sets of bearing seats 24 are also bolted to the side frame 2. Lead screws 242 are mounted on each bearing seat 24, with the upper end of the lead screw 242 connected to the output shaft of the second motor 231. An auxiliary rod 241 is bolted between the bearing seats 24 and the motor mounts 23. Lifting seats 25 are mounted on the lead screws 242. A lifting mechanism is installed between the four sets of lifting seats 25. The lifting seat 26 has two sets of rollers 251 mounted on it, both of which are in contact with the auxiliary rod 241. A pressure roller 261 is mounted on the lower end of the lifting seat 26, and a pulley is mounted on the shaft of the pressure roller 261. A fixing plate 262 is bolted to the front end of the lifting seat 26, and a third motor 263 is bolted to the fixing plate 262. A pulley is fixed to the output shaft of the third motor 263, and the pulley on the output shaft of the third motor 263 is connected to the pressure roller. A belt connects the pulleys on shaft 261. Pressure roller 261 is located directly above the two sets of idler rollers 21. Its function is as follows: When motor 231 starts, its output power drives screw 242 to rotate. The lifting seat 25 installed on screw 242 moves vertically under the rotation of screw 242. Since the four sets of lifting seats 25 support the lifting seat 26 together, the height of the lifting seat 26 is precisely adjusted. When motor 263 starts, its output power is transmitted to pressure roller 261 through belt, driving pressure roller 261 to rotate. Pressure roller 261, located directly above the two sets of idler rollers 21, can perform pre-treatment operations such as compaction and leveling on the material placed on idler roller 21, and drive the material to the right. During the lifting of lifting seat 25 with screw 242, roller 251 is always in contact with auxiliary rod 241. Auxiliary rod 241 provides stable guidance for the lifting of lifting seat 25, effectively preventing the lifting seat 25 from shaking or deviating during the lifting process.

[0024] The working principle of this embodiment is as follows: The material to be cut is placed on two sets of rollers 21 on the side frame 2. The second motor 231 on the side frame 2 is started. The output shaft of the second motor 231 drives the lead screw 242 to rotate. The lifting seat 25 on the lead screw 242 moves vertically accordingly. Since the four sets of lifting seats 25 support the lifting seat 26 together, the height of the lifting seat 26 can be precisely adjusted, so that the pressure roller 261 installed at its lower end is close to the material. During the lifting and lowering process of the lifting seat 25, the rollers 251 on the lifting seat 25 roll along the auxiliary rod 241. The auxiliary rod 241 plays a stabilizing and guiding role, ensuring that the pressure roller 261 rises and falls smoothly without deviation. The third motor 263 on the fixed plate 262 is started. The output shaft of the third motor 263 drives the shaft of the pressure roller 261 to rotate through the belt. The pressure roller 261 begins to perform pre-treatment operations such as compaction and flattening on the material located on the roller 21, so that the material reaches a suitable state for cutting. The pre-treated material is then passed through the support rollers. Roller 21 conveys the material to connecting plate 22. Since connecting plate 22 and support plate 17 are at the same height, the material can be smoothly transferred to support plate 17 and moved to the predetermined cutting position along the through groove between support plate 17 and spacer block 171. The operator presses down the handle 151 on the pressure rod 15. The pressure rod 15 rotates around the pin shaft and transmits pressure to the movable plate 16 through connecting plate 161 and round rod 162. Under the guidance of buffer rod 164, the movable plate 16 moves steadily downward, driving the cutting blade 165 installed at its lower end to cut downward along the rectangular through groove on the lower pressure plate 163, completing the cutting operation of the material. After the cutting is completed, the sample falls through the discharge trough 12. At this time, the first motor 32 on the mounting plate 3 is started. The output shaft of the first motor 32 drives the pulley to rotate, and through the transmission belt 321, drives the receiving plate 31 to slide on the slide rail to catch the sample falling from the discharge trough 12, realizing the automatic collection of the sample and completing the entire ring-crushed sample cutting process.

[0025] The following points should be noted in this article: 1. The accompanying drawings of the embodiments disclosed herein only relate to the structures involved in the embodiments disclosed herein; other structures can be referred to in general design.

[0026] 2. Where there is no conflict, the embodiments of this disclosure and the features in the embodiments can be combined with each other to obtain new embodiments.
