Description

Technical Field

[0001] This application relates to the field of cardboard box strength testing technology, and in particular to a cardboard box strength testing device. Background Technology

[0002] Cardboard boxes are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc., and there are various specifications and models. Cardboard boxes commonly have three or five layers, while seven layers are less common. Each layer consists of linerboard, corrugated paper, core paper, and face paper. Linerboard and face paper are usually made of kraft paper or kraft paper, while the core paper is made of corrugated paper.

[0003] Regarding the aforementioned technologies, the inventors believe the following problems still exist:

[0004] Firstly, most existing cardboard box testing equipment uses a motor to drive a pressure testing tool to directly test the cardboard box. This results in the cardboard box being subjected to stable pressure until it breaks. However, this may lead to inaccurate measurement data.

[0005] Secondly, most existing carton testing equipment directly applies pressure to the carton without setting up fixing or limiting devices on the side. This makes the carton susceptible to uneven pressure and deformation during pressure testing.

[0006] To address the aforementioned problems, the inventors have proposed a cardboard box strength testing device to solve these issues. Utility Model Content

[0018] 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.

[0019] Example: Figure 1-3 As shown, this utility model provides a carton strength testing device, including a support 1. A pressing mechanism 2 is fixedly installed on one side of the support 1, and a fixing mechanism 3 is provided at the bottom end of the pressing mechanism 2. The fixing mechanism 3 is fixedly installed at the bottom end of the support 1. The pressing mechanism 2 includes a pressure gauge 201, which is fixedly installed on the upper inner wall of the support 1. A spring 202 is fixedly installed at the bottom end of the pressure gauge 201. The pressure gauge 201 can measure the pressure on the carton. A sliding plate 203 is fixedly installed at the bottom end of the spring 202. The sliding plate 203 is slidably connected to one side of the support 1, allowing the sliding plate 203 to slide on one side of the support 1, making it move downward more stably. A support plate 207 is fixedly installed on the side of the sliding plate 203 facing away from the support 1. The bottom ends of the sliding plate 203 and the support plate 207 are fixedly connected. A pressure block 208 is fixedly installed, which can apply pressure to the carton. A connecting rod 206 is rotatably installed on the top of the sliding plate 203, and a protrusion 205 is rotatably installed on the top of the connecting rod 206. The protrusion 205 is trapezoidal and is rotatably installed on one side of the bracket 1. A pressure rod 204 is fixedly installed on one end of the protrusion 205, which can better press the sliding plate 203. By using the pressure rod 204 on the pressing mechanism 2 to drive the sliding plate 203 to move, the sliding plate 203 and the support plate 207 drive the pressure block 208 to perform pressure testing on the carton. At the same time, the sliding plate 203 can drive the pressure gauge 201 to rotate through the spring 202, so that the pressure gauge 201 can detect. By manually pressing, the pressure on the carton can be changed. After multiple measurements, the data can be made more accurate.

[0020] The fixing mechanism 3 includes a housing 302. A motor 301 is fixedly mounted on one side of the housing 302. A first bevel gear 304 is fixedly mounted on the output end of the motor 301. A second bevel gear 305 is meshed with one side of the first bevel gear 304. The motor 301 can drive the first bevel gear 304 to rotate, which in turn drives the two second bevel gears 305 to rotate. A threaded rod 307 is fixedly mounted on the side of the second bevel gear 305 facing away from the first bevel gear 304. A threaded block 306 is threadedly fitted on the outer surface of the threaded rod 307. The two second bevel gears 305 can drive the two threaded rods 307 to rotate, causing the threaded rods 307 to rotate inside the housing 302. A fixing block 303 is fixedly mounted on one side of the threaded block 306, away from the threaded block 306. One end of 06 is L-shaped. The L-shaped fixing block 303 can fix the carton more stably, making the carton less prone to deformation. A sliding groove 308 is opened on one side of the shell 302 to cooperate with the fixing block 303. A friction pad 309 is fixedly installed on the lower inner wall of the bracket 1. Multiple L-shaped positioning blocks 310 are fixedly installed on one side of the lower inner wall of the bracket 1. The L-shaped positioning blocks 310 can support the carton more stably. The motor 301 drives the first bevel gear 304, and the first bevel gear 304 drives the two threaded rods 307 to rotate through the second bevel gears 305 on both sides. The two threaded rods 307 slide in the sliding groove 308 and drive the fixing block 303 to fix the carton and prevent it from deforming during testing.

[0021] Working principle: First, place the carton to be measured on the friction pad 309 and press one side of the carton against the positioning block 310. Then, start the motor 301. The motor 301 drives the first bevel gear 304 to rotate. The first bevel gear 304 drives the two second bevel gears 305 to rotate. The two second bevel gears 305 drive the two threaded rods 307 to rotate. The threaded rods 307 rotate inside the housing 302. The threaded rods 307 drive the threaded block 306 to move. The threaded block 306 drives the fixing block 303 to move. The fixing block 303 slides in the slide groove 308 and fixes the carton to prevent it from deforming during testing.

[0022] Then, press the pressure lever 204, causing the pressure lever 204 to move the protrusion 205 downward. The protrusion 205 then moves the connecting rod 206 downward. The connecting rod 206 moves the sliding plate 203 along the bracket 1. At the same time, the sliding plate 203 moves the support plate 207 downward. The sliding plate 203 and the support plate 207 simultaneously move the pressure block 208 to perform a pressure test on the carton. The highest pressure that the carton can withstand will be transmitted to the pressure gauge 201 through the spring 202. It is only necessary to record the results afterward.

[0023] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
