Description

Technical Field

[0001] This utility model relates to the field of packaging compression equipment technology, specifically a bubble control device based on triaxial compression. Background Technology

[0002] In the logistics, warehousing and packaging industries, cushioning materials such as foam and bubble wrap are widely used because of their lightweight and good shock resistance. However, these materials are bulky and occupy a lot of transportation and storage space, significantly increasing logistics costs. In order to improve loading efficiency and reduce transportation costs, they usually need to be compressed before shipment to reduce their volume to the specified size.

[0003] Currently, most common compression equipment is a unidirectional or bidirectional compression mechanism, which has limited compression direction and makes it difficult to achieve precise control of the three-dimensional dimensions of the product. This can easily lead to problems such as irregular shape and high rebound rate after compression. In addition, traditional compression equipment relies heavily on manual measurement and operation, resulting in low automation.

[0004] Therefore, there is an urgent need for a method that can achieve independent control of three axes and high compression accuracy to meet the needs of quantitative compression and standardized processing of foam products. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a bubble control device based on triaxial compression, which solves the aforementioned problems.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model is implemented through the following technical solution: a bubble control and volume measurement device based on triaxial compression, comprising a housing, a dual-axis compression assembly disposed within the housing, a vertical plate fixed to the rear top of the housing, a linear actuator disposed at the front end of the vertical plate, a Z-axis pressure plate connected to the drive end of the linear actuator, a work display disposed on the vertical plate, a top plate connected to the top of the vertical plate, and a monitoring camera and a barcode reader camera disposed at the bottom of the top plate;

[0009] The dual-axis compression assembly includes a housing, an X-axis pressure plate and a Y-axis pressure plate disposed within the housing, and a first driving assembly and a second driving assembly for driving the X-axis pressure plate and the Y-axis pressure plate, respectively; the X-axis pressure plate and the Y-axis pressure plate are arranged alternately; the first driving assembly and the second driving assembly have the same structure and are both installed below the housing.

[0010] By adopting the above technical solution and setting up a combination structure of biaxial compression component and Z-axis pressure plate, independent and controllable compression of product in the X, Y and Z directions is achieved. The structure is compact, easy to operate, and can accurately control the compression volume. It is suitable for quantitative compression and measurement of foam and bubble products.

[0011] Preferably, both the X-axis pressure plate and the Y-axis pressure plate include a square tube, a column, a movable block, a movable plate, and a positioning wheel; the square tube is fixed between the two columns, the movable block is located on the outside of the column and is fixedly connected to the movable plate; the movable plate is located on the outside of the box, and the box has a sliding groove corresponding to the movable block around its perimeter, and the positioning wheel is installed at the corner of the outer side of the movable plate.

[0012] By adopting the above technical solution, the cooperation between the slide and the movable block achieves smooth guidance, and the positioning wheel further restricts the swing of the movable plate, ensuring that the X-axis pressure plate and the Y-axis pressure plate do not deviate during the movement, thereby improving the compression accuracy and stability.

[0013] Preferably, both the first driving assembly and the second driving assembly include a fixed frame, a screw, a motor, a slider, and a U-shaped plate; the motor is mounted on the fixed frame and is used to drive the screw; the screw passes through the slider and is threadedly connected to it; the bottom of the U-shaped plate is fixedly connected to the slider, and its two vertical portions are located between the positioning wheels on both sides of the movable plate.

[0014] By adopting the above technical solution, a structure in which a motor-driven screw drives a slider in linear motion is used, resulting in high transmission accuracy and rapid response. The U-shaped plate and positioning wheel work together to achieve a smooth transmission without loosening, preventing the pressure plate from shaking during compression and improving the rigidity and control accuracy of the overall structure.

[0015] Preferably, the square tubes are provided in multiple units, equidistantly arranged between the two columns, and the gap between adjacent square tubes allows another square tube in the same direction to pass through.

[0016] By adopting the above technical solution, the X-axis pressure plate and the Y-axis pressure plate can be completely intersected and do not interfere with each other, realizing bidirectional independent compression. At the same time, it ensures uniform pressing surface, avoids local stress concentration in the product, and improves the compression effect and product shape retention.

[0017] Preferably, the linear actuator is vertically fixed to one side of the front end of the upright plate, and the work display is located on the other side of the front end of the upright plate.

[0018] By adopting the above technical solution, the linear actuator independently drives the Z-axis pressure plate, which has a simple structure and a small duty cycle; the operation display allows operators to view product information and compression status in real time, improving human-machine interaction efficiency.

[0019] Preferably, the monitoring camera is used to film the product compression process, and the barcode reader camera is used to scan the product's QR code.

[0020] By adopting the above technical solutions, the entire process of automatic product information identification and compression can be monitored through a vision system, which facilitates data traceability and quality control, and improves the level of automation and the reliability of production management.

[0021] Preferably, the X-axis pressure plate and the Y-axis pressure plate are initially positioned close to two adjacent inner walls of the housing.

[0022] By adopting the above technical solution, the pressure plate can be folded into the inside of the box when not in operation, saving space, avoiding interference, facilitating the insertion and removal of products, protecting the pressure plate structure, and extending its service life.

[0023] (III) Beneficial Effects

[0024] This invention provides a bubble control and volume measurement device based on triaxial compression. It has the following beneficial effects:

[0025] 1. Through the combined design of the dual-axis compression assembly and the Z-axis pressure plate, the product can be independently controlled and compressed in the X, Y, and Z directions. It can accurately control the size and volume of the compressed product, and is suitable for quantitative compression of foam products of different specifications. It has good compression consistency and regular shape.

[0026] 2. The design employs a square tubular grid cross-plate system, ensuring that the X-axis and Y-axis pressure plates do not interfere with each other during movement. This results in a compact overall structure and high space utilization. The guide mechanism, combining the sliding groove and movable block with the transmission system of the positioning wheel and U-shaped plate, ensures smooth, wobbly movement of the pressure plates, enhancing the stability and reliability of the compression process.

[0027] 3. Integrating barcode readers and monitoring cameras enables automatic identification of product information and full-process visual management of compression, supporting data storage and traceability, and improving the level of intelligent production management.

[0039] The following is in conjunction with the appendix Figure 1 -Appendix Figure 7 This application will be described in further detail below.

[0040] like Figures 1 to 3 As shown, the present invention provides a bubble control and volume measurement device based on triaxial compression, the overall structure of which mainly includes a housing 1, a dual-axis compression assembly 2, a vertical plate 3, a linear actuator 4, a Z-axis pressure plate 5, a work display 6, a top plate 7, a monitoring camera 8, and a code reader camera 9.

[0041] The housing 1 forms the main support frame of the device. The dual-axis compression assembly 2 is fixedly installed inside the housing 1 for compressing the product horizontally (i.e., in the X and Y axes). The vertical plate 3 is vertically fixed to the rear side of the top of the housing 1. The linear actuator 4 (which can be an electric cylinder, pneumatic cylinder, or hydraulic cylinder, etc.) is vertically installed on one side of the front end face of the vertical plate 3, with its drive end extending downward and fixedly connected to the Z-axis pressure plate 5, thereby driving the Z-axis pressure plate 5 to perform vertical (i.e., Z-axis) lifting and lowering movements to achieve third-axis compression of the product. The operation display 6 is installed on the other side of the front end face of the vertical plate 3 for displaying product information, compression parameters, and equipment status. The top plate 7 is horizontally fixedly connected to the top of the vertical plate 3 and is located directly above the dual-axis compression assembly 2. The monitoring camera 8 and the barcode reader 9 are both installed at the bottom of the top plate 7. The barcode reader 9 is used to scan the QR code placed on the product inside the dual-axis compression assembly 2 to automatically obtain product information; the monitoring camera 8 is used to record the entire compression process of the product, facilitating quality traceability and process monitoring.

[0042] Combination Figure 3 and Figure 4 The biaxial compression assembly 2 includes a top-open housing 21, an X-axis pressure plate 22 and a Y-axis pressure plate 23 disposed inside the housing 21, and a first drive assembly 24 and a second drive assembly 25 for independently driving the X-axis pressure plate 22 and the Y-axis pressure plate 23, respectively. The X-axis pressure plate 22 and the Y-axis pressure plate 23 are spatially staggered within the housing 21, meaning their compression surfaces intersect vertically without interfering with each other, thus enabling compression of the product from two mutually perpendicular horizontal directions. The first drive assembly 24 and the second drive assembly 25 have identical structures, both installed below the housing 21, and connected to the X-axis pressure plate 22 and the Y-axis pressure plate 23 respectively via transmission mechanisms.

[0043] like Figure 5 and Figure 6As shown, the X-axis pressure plate 22 and the Y-axis pressure plate 23 have the same modular structure. Taking the X-axis pressure plate 22 as an example, it mainly includes two vertical columns 222, multiple horizontal square tubes 221, a movable block 223, a movable plate 224, and positioning wheels 225. The multiple square tubes 221 are fixedly connected between the two vertical columns 222 in parallel and at equal intervals, forming a grid-like pressing plane. The movable block 223 is fixedly installed on the outer side of the column 222. The movable plate 224 is located on the outer side of the housing 21 and is fixedly connected to the movable block 223. A sliding groove 26 extending along the compression direction is provided on the side wall of the housing 21. The movable block 223 passes through the sliding groove 26, so that the entire pressure plate (including the column 222 and the square tubes 221) can slide smoothly along the sliding groove 26 with the movable plate 224. Multiple positioning wheels 225 are installed at the corners of the outer side of the movable plate 224 to provide guidance and limit during driving and prevent the movable plate 224 from swinging.

[0044] The X-axis pressure plate 22 has uniform gaps between its multiple square tubes 221. Similarly, the Y-axis pressure plate 23 has the same grid structure. It is because of these gaps that the square tubes 221 of the X-axis pressure plate 22 can pass through the gaps between the square tubes 221 of the Y-axis pressure plate 23, and vice versa, thus achieving complete intersection between the two and preventing them from obstructing each other during compression.

[0045] like Figure 6 and Figure 7 As shown, the first driving assembly 24 (the second driving assembly 25 is the same) specifically includes a fixed frame 241, a screw 242, a motor 243, a slider 244, and a U-shaped plate 245. The fixed frame 241 is fixedly installed at the bottom of the housing 21. The motor 243 (such as a servo motor or stepper motor) is installed at one end of the fixed frame 241, and its output shaft is connected to the screw 242 to drive the screw 242 to rotate around its own axis. The slider 244 is sleeved on the screw 242 and is threadedly engaged with the screw 242. The fixed frame 241 is provided with a guide rail or guide groove to restrict the slider 244 to slide only along the axial direction of the screw 242. When the motor 243 drives the screw 242 to rotate, the slider 244 makes a precise linear movement along the screw 242. The bottom horizontal part of the U-shaped plate 245 is fixedly connected to the top of the slider 244, and its two sides are vertically upward side plates. The two vertical side plates of the U-shaped plate 245 are located between the positioning wheels 225 on both sides of the movable plate 224, forming a clamping fit. When the U-shaped plate 245 moves with the slider 244, it pushes the positioning wheels 225 through its side plates, thereby driving the movable plate 224, the movable block 223 and the entire pressure plate to move synchronously, achieving precise feed and return control.

[0046] In the initial state (non-working state), the X-axis pressure plate 22 and Y-axis pressure plate 23, under the action of their respective drive components, retract and move closer to the two adjacent inner side walls of the housing 21, so that the largest possible accommodating space is formed in the center of the housing 21, which facilitates the insertion and removal of products.

[0047] During operation, the operator places the product to be compressed (such as a foam box, bubble bag, etc.) into the housing 21. The barcode reader 9 located at the top automatically scans the QR code on the product, reads the product information (such as model, target compression volume, etc.) and displays it on the work display 6, and can also transmit it to the control system.

[0048] After the compression process begins, the control system first controls the first drive assembly 24 and the second drive assembly 25 to work based on the product information. The motor 243 drives the screw 242 to rotate, which in turn drives the slider 244 and the U-shaped plate 245 to move, thereby driving the X-axis pressure plate 22 and the Y-axis pressure plate 23 to move from both sides of the housing 21 towards the center, compressing the product synchronously or stepwise in the X-axis and Y-axis directions until the preset planar dimensions are achieved.

[0049] After horizontal compression is completed, the product is confined within the compression space formed by the X-axis pressure plate 22 and the Y-axis pressure plate 23, and is located directly below the Z-axis pressure plate 5. Subsequently, the control system activates the linear actuator 4, driving the Z-axis pressure plate 5 to move downwards, performing vertical compression of the product in the Z-axis direction until the final preset overall compressed volume is reached.

[0050] After compression, the linear actuator 4 drives the Z-axis pressure plate 5 to rise and reset, while the first drive assembly 24 and the second drive assembly 25 also drive the X-axis pressure plate 22 and the Y-axis pressure plate 23 back to their initial positions. The operator can then remove the compressed and shaped product, thus completing one work cycle. The entire compression process is continuously recorded by the monitoring camera 8, creating a visual process archive.

[0051] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
