Description

Technical Field

[0001] This utility model belongs to the field of box liner forming, specifically, it relates to a suction cup gripper structure for a box liner forming machine. Background Technology

[0002] The liner of a refrigerator or freezer is the inner part located inside the outer shell of the refrigeration equipment used to hold items. It is an important component of the refrigeration equipment, and its performance directly affects the equipment's performance and lifespan. Liners generally use a one-piece molding technology, where ABS or HIPS resin (mixed with antioxidants, masterbatches, and other additives) is extruded into a continuous flat sheet. The cut sheet is then placed in the heating device of a vacuum forming machine and heated to a softened state using infrared or hot air, making it malleable. The softened sheet is then placed over a custom-made liner mold, and a vacuum is activated inside the mold. Under atmospheric pressure and vacuum negative pressure, the sheet adheres tightly to the inner wall of the mold. After cooling and shaping, the waste edges of the opening are trimmed, forming a complete, seamless liner body. In existing technologies, the trimmed waste edges remain on the mold forming table and are cleaned by workers, which is inefficient and prone to safety accidents.

[0003] To address the aforementioned issues, patent application number 2017212758974 discloses a multi-station vacuum forming machine for box liners, comprising a support frame, a conveyor chain fixedly connected to one side of the base, a heating device installed in the middle of the support frame above the conveyor chain, an electric telescopic rod installed at the lower end of the support frame, a forming mold fixedly connected to the upper end of the electric telescopic rod, the forming mold located behind the heating device, an electrical control box connected to one side of the support frame, a proximity sensor located between the heating device and the forming mold in the middle of the conveyor chain, the electric telescopic rod and the proximity sensor electrically connected to the electrical control box, a fan connected to the rear end of the support frame, a foot-cutting machine installed on one side of the fan, and a fixing plate installed on one side of the support frame, but this does not solve the aforementioned problems.

Detailed Implementation

[0015] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0016] Figure 1 This is a schematic diagram of the suction cup gripper structure of the box liner forming machine in an embodiment of this utility model.

[0017] like Figure 1As shown, the suction cup gripper structure for the box liner forming machine provided by this utility model includes a suction cup frame 10, a box liner main body suction cup unit 20, and a waste material edge suction cup unit 30. The box liner main body suction cup unit 20 is mounted on the suction cup frame 10, and the waste material edge suction cup unit 30 is mounted on the suction cup frame 10. The box liner main body suction cup unit 20 can adsorb and grip the formed box liner 1, and the waste material edge suction cup unit 30 can adsorb and grip the trimmed waste material edge 2, avoiding the problem of waste material edge 2 remaining on the mold forming table after the box liner 1 is removed. This helps to reduce the labor intensity of workers, improve production efficiency, and enhance the safety of the production process.

[0018] The suction cup frame 10 includes a load-bearing beam 11, a mounting beam 12, and a mounting flange 13. The mounting beam 12 is connected to the load-bearing beam 11. The load-bearing beam 11 and the mounting beam 12 are arranged parallel to each other. The four mounting beams 12 are arranged parallel to each other and evenly distributed on the load-bearing beam 11, which helps to improve the load-bearing capacity of the suction cup frame 10. The mounting flange 13 is connected to the load-bearing beam 11. The mounting flange 13 is used to connect the suction cup frame 10 to the lifting and translating mechanism, so that the lifting and translating mechanism can drive the suction cup frame 10 to lift or translate, which facilitates the picking and transfer of materials in the box liner 1.

[0019] Figure 2 This is a schematic diagram of the structure of the suction cup unit of the box liner body in an embodiment of this utility model.

[0020] like Figure 2 As shown, the suction cup unit 20 of the inner container body is set on the mounting beam 12. The suction cup unit 20 of the inner container body includes a mounting plate 21, a first suction cup rod 22, a sleeve 23 and a first suction cup 24. The mounting plate 21 is set on the mounting beam 12, the sleeve 23 is set on the mounting plate 21, the first suction cup rod 22 is movably inserted into the sleeve 23 and can slide along the sleeve 23 in the vertical direction, and the first suction cup 24 is set at one end of the first suction cup rod 22. Multiple sets of suction cup units 20 of the inner container body are evenly arranged on the mounting beam 12, so that the suction cup unit 20 of the inner container body can stably adsorb and grasp the inner container 1, improve the reliability of the structure, and facilitate the picking and transfer of the inner container 1.

[0021] like Figure 2As shown, the end of the first suction cup rod 22 away from the first suction cup 24 is provided with a first limiting protrusion 221. The first limiting protrusion 221 can prevent the first suction cup rod 22 from slipping out of the sleeve 23, which improves the reliability of the structure and avoids the first suction cup rod 22 and the first suction cup 24 from falling off, which would cause the box liner 1 to fall off accidentally, thus improving the safety of the production process. A first buffer spring 25 is provided on the first suction cup rod 22. The first buffer spring 25 is located between the first suction cup 24 and the sleeve 23, which buffers the first suction cup 24 when it contacts the box liner 1, avoiding direct contact with the box liner 1 and causing defects such as pits on the surface of the box liner 1, thus improving the molding quality of the box liner 1.

[0022] Figure 3 This is a schematic diagram of the waste material side suction cup unit in an embodiment of this utility model. Figure 1 .

[0023] like Figure 3 As shown, the waste edge suction cup unit 30 includes a slide bar seat 31, a slide bar 32, a second suction cup rod 33, and a second suction cup 34. The slide bar seat 31 is mounted on the mounting beam 12. The slide bar 32 is movably inserted into the slide bar seat 31, allowing it to slide vertically along the slide bar seat 31. One end of the second suction cup rod 33 is connected to the slide bar 32, and the other end is connected to the second suction cup 34, allowing the second suction cup 34 to move vertically up and down with the movement of the slide bar 32, facilitating the suction cup 34 to adsorb and grasp the waste edge 2. A second limiting protrusion 321 is provided at the end of the slide bar 32 away from the second suction cup 34. The second limiting protrusion 321 prevents the slide bar 32 from slipping out of the slide bar seat 31, improving the reliability of the structure and avoiding the problem of the waste edge 2 falling off due to the slide bar 32, the second suction cup rod 33, and the second suction cup 34, thus improving safety during the production process.

[0024] Figure 4 This is a schematic diagram of the waste material side suction cup unit in an embodiment of this utility model. Figure 2 ; Figure 5 This is a cross-sectional view of the waste material suction cup unit in an embodiment of this utility model.

[0025] like Figure 4 and Figure 5As shown, a buffer sleeve 35 is provided between the second suction cup rod 33 and the slide rod 32. One end of the second suction cup rod 33 is provided with a sliding flange 331, which is movably disposed inside the buffer sleeve 35. Both ends of the buffer sleeve 35 are provided with anti-slip flanges. The buffer sleeve 35 is connected to the end of the slide rod 32, so that the second suction cup rod 33 and the slide rod 32 can be movably connected. A second buffer spring 36 is provided on the second suction cup rod 33. A limiting block 332 is provided on the second suction cup rod 33. The limiting block 332 is slidably sleeved on the second suction cup rod 33 and is connected to the buffer sleeve 35. The second buffer spring 36 is located between the second suction cup 34 and the limiting block 332, so as to buffer the first suction cup 24 when it contacts the box liner 1, avoid direct contact with the waste material edge 2 and the forming worktable, and prevent the slide rod 32 from bending under force. This helps to improve the service life of the waste material edge suction cup unit 30.

[0026] With the suction cup gripper structure of the box liner forming machine provided by this utility model, when adsorbing and gripping the box liner 1 and the waste material edge 2, the lifting and translation mechanism moves the suction cup frame 10 above the box liner 1 and drives the suction cup frame 10 to descend. The second suction cup 34 contacts the waste material edge 2. The suction cup frame 10 is still in the process of descending. The slide bar 32 slides in the slide bar seat 31 until the first suction cup 24 contacts the box liner 1. This allows the suction cup gripper structure of the box liner forming machine provided by this utility model to be applicable to the adsorption and gripping of box liners 1 and waste material edges 2 of various sizes.

[0027] The suction cup gripper structure for the box liner forming machine provided by this utility model includes a suction cup frame 10, a box liner main body suction cup unit 20, and a waste material edge suction cup unit 30. The box liner main body suction cup unit 20 is mounted on the suction cup frame 10, and the waste material edge suction cup unit 30 is mounted on the suction cup frame 10. The box liner main body suction cup unit 20 can adsorb and grip the formed box liner 1, and the waste material edge suction cup unit 30 can adsorb and grip the trimmed waste material edge 2, avoiding the problem of waste material edge 2 remaining on the mold forming table after the box liner 1 is removed. This helps to reduce the labor intensity of workers, improve production efficiency, and enhance the safety of the production process.
