Description

Technical Field

[0001] This invention relates to the field of food container processing technology, specifically to a molding device for processing disposable food containers. Background Technology

[0002] Disposable fast food containers have shifted from foam containers to environmentally friendly ones. Foam containers, which are not heat-resistant and whose manufacturing process damages the environment, have been phased out. They have been replaced by plastic, paper, wooden, and biodegradable containers, among others. Plastic, with its low toxicity, high melting point, strong plasticity, ease of production, and relatively low cost, has become the mainstream material for manufacturing disposable fast food containers.

[0003] A disposable lunchbox trimming device, as shown in Chinese Patent Publication No. CN121340599B, ​​includes: a fixed base plate; a guide plate and a drive motor are disposed below the fixed base plate; a first lifting and limiting groove is formed on the surface of the guide plate; a connecting pipe is connected below the drive motor; a limiting cutting plate is slidably sleeved on the surface of the connecting pipe; a sliding sleeve is fixedly installed in the middle of the limiting cutting plate; a connecting arm is disposed on one side of the sliding sleeve; a telescopic tube is installed at one end of the connecting arm; a telescopic rod is slidably inserted into the telescopic tube; a cutting head is installed at the end of the telescopic rod near the limiting cutting plate; during the process of the suction cup housing extending into the lunchbox, the edge of the lunchbox is in contact with the limiting cutting plate and lifts the limiting cutting plate; the limiting cutting plate drives the connecting arm to rise through the sliding sleeve and the rotating ring; the connecting arm drives the telescopic rod and the cutting head to rise synchronously through the telescopic tube, so that the cutting head is always located on the side of the limiting cutting plate, thereby realizing the processing of lunchboxes of different depths. Existing cutting devices lack the ability to actively and precisely adjust the cutting height, horizontal position, and cutting angle, making it difficult to adapt to the edge trimming needs of lunch boxes of different sizes and edge angles. The cutting method is static and rigid, which can easily lead to problems such as rough edges and tears on the cut edges of the lunch boxes, resulting in poor edge trimming quality.

[0016] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0017] like Figures 1-12 The disposable lunch box forming equipment shown includes a frame 1, a lunch box clamping mechanism and a trimming mechanism mounted on the frame 1. The lunch box clamping mechanism includes a pressing component and a bearing component. The trimming mechanism includes a vibratory cutting blade 2, a mounting frame 3, a horizontal adjustment device and an angle adjustment device. The cutting blade 2 achieves the vibratory cutting function through a micro-vibration drive device. The horizontal adjustment device is mounted on the mounting frame 3. The angle adjustment device is mounted on the horizontal adjustment device. The angle adjustment device includes an angle adjustment frame 4, a first linear actuator 5, a reciprocating push rod 6 and an automatic height adjustment component. The first linear actuator 5 is fixedly mounted on a sliding seat 7. One end of the reciprocating push rod 6 is hinged to the output end of the first linear actuator 5, and the other end of the reciprocating push rod 6 is hinged to the top end of the angle adjustment frame 4. The automatic height adjustment component is hinged to the angle adjustment frame 4 and the hinge height is consistent with the lunch box cutting position. The cutting blade 2 is mounted on the angle adjustment frame 4.

[0018] This invention achieves precise clamping of the lunchbox blank through the cooperation of the pressing component and the supporting component, avoiding displacement during processing that could affect molding accuracy. The edge trimming mechanism is responsible for trimming the edges of the lunchbox. The vibratory cutting blade 2 improves cutting efficiency and cut smoothness through vibration, effectively reducing tearing and burrs in the lunchbox material compared to traditional static cutting. The mounting frame 3 provides a mounting carrier for the various adjustment components of the edge trimming mechanism. The horizontal adjustment device is used to adjust the horizontal position of the cutting blade 2 to adapt to the edge trimming requirements of lunchboxes of different sizes. The angle adjustment device can adjust the cutting angle of the cutting blade 2 to meet the processing requirements of different edge tilt angles of the lunchbox. The vibration cutting function of the cutting blade 2 is realized through a micro-vibration drive device. When the eccentric structure of the micro-vibration drive device rotates, it drives the cutting blade 2 to reciprocate, thereby achieving a vibration cutting effect. When the first linear actuator 5 extends or retracts, it pushes the angle adjustment frame 4 to rotate around the hinge point through the reciprocating push rod 6, thereby adjusting the angle of the angle adjustment frame 4 and the cutting blade 2. The automatic height adjustment component is hinged to the angle adjustment frame 4, and the hinge height is consistent with the cutting position of the lunch box. It is used to automatically adjust the hinge height of the angle adjustment frame 4 according to the actual height of the lunch box, so as to ensure that the cutting blade 2 always accurately corresponds to the cutting position of the lunch box and improve the cutting accuracy. The cutting blade 2 is installed on the angle adjustment frame 4, and the cutting angle changes synchronously with the angle adjustment frame 4 to adapt to the cutting needs of different lunch box edges.

[0019] The mounting bracket 3 is provided with an adjustable position limit block 8. The horizontal adjustment device includes a sliding seat 7 that is horizontally slidably disposed on the mounting bracket 3. The sliding seat 7 is provided with an abutment block 9. The angle adjustment device is installed on the sliding seat 7 and is connected to the cutting blade 2 in a transmission manner.

[0020] The adjustable position limit stop 8 on the mounting bracket 3 is used to limit the sliding stroke of the horizontal adjustment device, preventing over-adjustment that could damage the mechanism or cause cutting position deviation. Its position can be flexibly adjusted according to actual processing needs. The sliding seat 7 of the horizontal adjustment device serves as the mounting carrier for the angle adjustment device. Horizontal movement of the angle adjustment device and the cutting blade 2 is achieved through horizontal sliding. The abutment block 9 on the sliding seat 7 can cooperate with the limit stop 8 to form a mechanical limit, improving the accuracy of horizontal adjustment. The angle adjustment device is mounted on the sliding seat 7 and connected to the cutting blade 2 via a transmission mechanism. After the angle adjustment device completes the horizontal position adjustment with the sliding seat 7, it can drive the cutting blade 2 to achieve angle adjustment through its own transmission structure, ensuring that the position and angle of the cutting blade 2 can accurately adapt to the edge trimming requirements of the lunch box.

[0021] The leveling device also includes an elastic telescopic rod 10, a rotating wheel 11, a threaded rod 12, and a threaded seat 13 that mates with the threaded rod 12. The threaded seat 13 is provided with a locking pin 14 that locks with the mounting bracket 3. The rotating wheel 11 is fixedly connected to the threaded rod 12, and the limiting block 8 is fixedly connected to the threaded seat 13. The elastic telescopic rod 10 is composed of a telescopic sleeve and a built-in spring. One end of the telescopic sleeve is connected to the mounting bracket 3, and the other end of the telescopic sleeve is connected to the sliding seat 7. The leveling device is provided with a reset device.

[0022] The elastic telescopic rod 10 consists of a telescopic sleeve and a built-in spring. One end is connected to the mounting bracket 3, and the other end is connected to the sliding seat 7. It provides elastic support and reset assistance when the sliding seat 7 moves horizontally. The built-in spring can buffer the impact force when the sliding seat 7 moves, and at the same time, it helps the sliding seat 7 maintain a stable position after adjustment. The rotating wheel 11, the threaded rod 12, and the threaded seat 13 constitute the transmission mechanism for horizontal adjustment. Rotating the rotating wheel 11 can drive the threaded rod 12 to rotate. Utilizing the threaded engagement between the threaded rod 12 and the threaded seat 13, the threaded seat 13 is driven to move axially along the threaded rod 12, thereby realizing the position adjustment of the limit stop 8 fixedly connected to the threaded seat 13. The locking pin 14 on the threaded seat 13 is used to lock the threaded seat 13 to the mounting bracket 3 after the position of the limit stop 8 is adjusted, preventing the threaded seat 13 from loosening during processing and causing the limit stop 8 to shift. The reset device is used to drive the sliding seat 7 back to the initial position after horizontal adjustment or when reset is required, improving the ease of operation and adjustment consistency of the equipment.

[0023] A sliding rod 15 is installed on the sliding seat 7. The sliding rod 15 is slidably connected to the mounting frame 3. The sliding rod 15 is provided with a sliding damper 16. A transmission rod 17 is also installed on the sliding seat 7. The bottom of the mounting frame 3 is provided with an inclined reset block 18 that can be raised and lowered. The inclined reset block 18 can abut against the transmission rod 17. The sliding damper 16 on the sliding rod 15 can adjust the moving speed of the sliding seat 7, avoiding excessive movement that could cause mechanical impact and affect the cutting effect, while also enhancing the stability of the sliding seat 7 after adjustment. The transmission rod 17 is mounted on the sliding seat 7 and cooperates with the inclined reset block 18 at the bottom of the mounting bracket 3 to achieve auxiliary reset of the sliding seat 7. The inclined reset block 18 is adjustable in height. When reset is required, the inclined reset block 18 rises and contacts the transmission rod 17, using the guiding effect of the inclined surface to drive the sliding seat 7 to move and reset. This structure can improve the smoothness and reliability of the reset process and avoid violent collisions during reset.

[0024] The micro-vibration drive device includes a drive motor 19, a blade mounting plate 20, a limiting plate 21, a rotating shaft 22, and an eccentric wheel 23. The blade mounting plate 20 is slidably mounted on the angle adjustment device, the drive motor 19 is fixedly mounted on the angle adjustment device, there are two limiting plates 21 located at the upper and lower ends of the eccentric wheel 23 respectively, the limiting plates 21 are in contact with the surface of the eccentric wheel 23, and the output end of the drive motor 19 is fixedly connected to the eccentric wheel 23 through the rotating shaft 22.

[0025] After the drive motor 19 starts, it drives the rotating shaft 22 and the eccentric wheel 23 to rotate. During the rotation, the eccentric structure of the eccentric wheel 23 continuously pushes the blade mounting plate 20 to slide up and down along the angle adjustment device through the limiting plate 21, thereby driving the cutting blade 2 to perform high-frequency micro-reciprocating vibration, realizing the vibration cutting function, and improving the efficiency and cut quality of the lunch box edge trimming. The two limiting plates 21 are located at the upper and lower ends of the eccentric wheel 23 respectively and are in contact with the surface of the eccentric wheel 23. They are used to limit the rotation trajectory of the eccentric wheel 23, prevent the eccentric wheel 23 from deviating during rotation, and ensure stable contact between the eccentric wheel 23 and the blade mounting plate 20.

[0026] The angle adjustment device also includes an anti-deviation component, which is installed on both sides of the angle adjustment frame 4 and connected to the angle adjustment frame 4 and the mounting frame 3.

[0027] Anti-deviation components are installed on both sides of the angle adjustment frame 4 to limit the rotation range of the angle adjustment frame 4, prevent excessive angle adjustment or deviation during rotation, and ensure the stability and accuracy of angle adjustment. The cutting blade 2 is installed on the angle adjustment frame 4, and the cutting angle changes synchronously with the angle adjustment frame 4 to adapt to the cutting needs of different lunch box edges.

[0028] The support assembly includes a bottom support frame 24, a telescopic support base 25, a pressure sensor, and an edge support frame 26. The pressure sensor is located between the telescopic support base 25 and the bottom support frame 24. The edge support frame 26 is mounted on a vertically arranged telescopic frame 27. The edge support frame 26 is horizontally arranged, and its top is densely covered with ball bearings 28. A positioning receiver 29 is located on the side of the edge support frame 26 near the angle adjustment device. A positioning sensor 30 is provided on the automatic height adjustment assembly. When clamping the lunchbox blank, after the pressing component presses down, the bottom support frame 24 provides basic installation support for the support component. The telescopic support seat 25 is used to adapt to lunchbox blanks of different thicknesses, and the support height can be adjusted by telescoping. The pressure sensor is used to detect the pressure on the telescopic support seat 25 in real time. When the lunchbox blank is pressed tightly by the pressing component, the pressure sensor can feed back a pressure signal to ensure that the clamping force is moderate, avoiding excessive pressure that damages the lunchbox or insufficient pressure that leads to unstable clamping. The edge support frame 26 can be adjusted in height via the telescopic frame 27 to adapt to the edge support requirements of lunchboxes of different sizes. The edge support frame 26 is horizontally positioned and densely covered with ball bearings 28 on its top. While supporting the edge of the lunch box, it reduces the friction between the lunch box and the edge support frame 26, ensuring that it does not interfere with the rotation process when the lunch box blank rotates. The positioning receiver 29 on the edge support frame 26 works in conjunction with the positioning sensor 30 on the automatic height adjustment component to detect whether the lunch box is placed in the correct position. When the lunch box is placed in the correct position, the positioning sensor 30 sends a signal to the positioning receiver 29, and the equipment can then start the subsequent processing flow, improving the safety and accuracy of the processing.

[0029] The automatic height adjustment assembly also includes a hinge bracket 31, a limit rod 32, a slider 33, a hinge seat 34, and a second linear actuator 35. The hinge bracket 31 is fixedly mounted on the sliding seat 7, the limit rod 32 is fixedly mounted on the hinge bracket 31, the slider 33 is slidably mounted on the limit rod 32, the hinge seat 34 is hinged to the slider 33, the hinge seat 34 is hinged to the angle adjustment frame 4, the second linear actuator 35 is fixedly mounted on the sliding seat 7, the output end of the second linear actuator 35 is fixedly connected to the slider 33, and the position sensor 30 is fixedly mounted on the slider 33.

[0030] When the second linear actuator 35 extends or retracts, it drives the slider 33 to slide along the limiting rod 32, which in turn pushes the angle adjustment frame 4 to move up and down around the hinge point through the hinge seat 34, thereby realizing the automatic adjustment of the height of the cutting blade 2. The position sensor 30 is fixedly installed on the slider 33 and cooperates with the position receiver 29 on the edge support frame 26. When the slider 33 moves to the corresponding height so that the cutting blade 2 is aligned with the cutting edge position of the lunch box, the position sensor 30 sends a signal, and the second linear actuator 35 stops moving to ensure the height adjustment accuracy. The slider 33 is slidably set on the limiting rod 32 and hinged to the hinge seat 34. The hinge seat 34 is then hinged to the angle adjustment frame 4 to form a transmission connection. When the slider 33 is displaced in height, it can drive the hinge seat 34 to move synchronously, thereby adjusting the hinge position of the hinge seat 34 on the angle adjustment frame 4, and will not interfere with the deflection process when the angle adjustment frame 4 is deflected.

[0031] The anti-deviation assembly includes an anti-deviation plate 36 and a lateral damping plate 37. The lateral damping plate 37 is fixedly installed on the sliding seat 7, and the anti-deviation plate 36 is fixedly installed on the angle adjustment frame 4. The anti-deviation plate 36 and the lateral damping plate 37 are in contact with each other.

[0032] The lateral damping plate 37 and the anti-deviation plate 36 work together to form a lateral limit. When the angle adjustment frame 4 rotates or the cutting blade 2 vibrates during operation, the contact between the anti-deviation plate 36 and the lateral damping plate 37 can limit the lateral displacement of the angle adjustment frame 4, preventing the angle adjustment frame 4 from shifting and affecting the cutting accuracy. At the same time, the lateral damping plate 37 has a shock absorption function, which can absorb the impact force generated by the vibration of the angle adjustment frame 4, reduce the impact of vibration on the overall structure of the equipment, and improve the stability and service life of the equipment.

[0033] The pressing assembly is equipped with a rotatable pressing head 38, a tilting rod 39, an automatic adjusting block 40, and a return spring 41. The pressing head 38 is equipped with a contact rubber pad. Several tilting rods 39 and automatic adjusting blocks 40 are provided and arranged in a ring around the pressing head 38. The tilting rod 39 is rotatably mounted on the automatic adjusting block 40 around its own axis. The automatic adjusting block 40 is slidably arranged along the radial direction of the pressing head 38. The two ends of the return spring 41 are mounted on the return mounting ring 42 provided on the outside of the automatic adjusting block 40 and the pressing head 38. The rubber pad on the pressure head 38 increases the friction between the pressure head 38 and the lunchbox blank, improving clamping stability and preventing damage to the lunchbox blank due to excessive hardness of the pressure head 38. The tilting rod 39 and the automatic adjustment block 40 allow the pressure head 38 to adaptively adjust itself by rotating and radially sliding the automatic adjustment block 40 when clamping lunchbox blanks of the specified size. During the pressing process, the tilting rod 39 automatically centers the lunchbox blank, ensuring full contact between the pressure head 38 and the lunchbox blank and improving clamping uniformity. The return spring 41 is mounted on the automatic adjustment block 40 and the return mounting ring 42. After the automatic adjustment block 40 is adjusted, the return spring 41 provides a restoring force, driving the automatic adjustment block 40 back to its initial position, ensuring consistency and reliability during the next clamping operation.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
