During the production and assembly process, the refrigerator forming machine needs to heat part of the plate, and then facilitate plastic forming through the mold. When the plate is heated, it will sag in the middle due to its own gravity. Therefore, it is necessary to fix the four sides of the plate during heating. The long side is generally clamped and fixed by the grabbing mechanism, and the two short sides of the remaining plate are fixed by the short side pressing device after the conveying mechanism conveys the plate to fix it.

Referring to patent application number CN201610109567.1, during use, the length of the short side pressing needs to be adjusted by manually turning the handle each time the plate is pressed and heated. The length of the short side pressing cannot be automatically adjusted according to the width of the plate, thereby increasing the workload of the workers. Summary of the invention

[0040] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0041] The present invention provides an automatic adjustment mechanism for the short side pressing material of the heating part of a refrigerator-type forming machine, which replaces the traditional method of adjusting the short side pressing material length of the heating part of the forming machine, avoids the need to manually adjust the short side pressing material length every time the heating part of the forming machine is used to press and heat the material, and avoids the problem that the automatic adjustment according to the width of the plate cannot be performed, thereby increasing the labor burden of the workers.

[0042] Figure 1-Figure 7 The structure diagram of the automatic adjustment mechanism of the short side pressing material of the heating part of the refrigerator type molding machine of the present invention is shown. Figure 1-Figure 7 The article provides a detailed introduction to the automatic adjustment mechanism of the short side pressing material in the heating part of this refrigerator type forming machine.

[0043] Example 1

[0044] refer to Figure 1-Figure 7 The present invention discloses an automatic adjustment mechanism for the short side pressing of a heating part of a refrigerator-type forming machine, the main body of which includes a pressing mechanism 100, a driving mechanism 200 and an adjusting mechanism 300.

[0045] refer to Figure 1-Figure 4 The pressing mechanism 100 is used to support the entire device and press the short side of the plate heated by the molding machine when the plate is heated. The pressing mechanism 100 includes a base 110, a top plate 120 located above the base 110, and a pressing plate assembly 130 located at the top of the base 110 and the bottom of the top plate 120. The base 110 is used to facilitate the installation of the pressing plate assembly 130, and the top plate 120 is used to facilitate the installation of the pressing plate assembly 130. The pressing plate assembly 130 is used to press the short side of the plate heated by the molding machine when the top plate 120 is close to the base 110.

[0046] refer to Figure 1-Figure 4The driving mechanism 200 is used to drive the top plate 120 to move closer to or away from the base 110 during operation, and then cooperate with the pressing plate assembly 130 to press or release the sheet. The driving mechanism 200 is installed on the base 110 and is in transmission connection with the top plate 120 and the pressing plate assembly 130. When the driving mechanism 200 is operating, the top plate 120 is driven to move closer to or away from the base 110, and when the top plate 120 moves downward and moves closer to the base 110, the pressing plate assembly 130 is automatically driven to extend to both sides. When pressing the short side of the sheet heated by the molding machine, the driving mechanism 200 drives the top plate 120 to move closer to the base 110. At the same time, during the downward movement of the top plate 120, the pressing plate assembly 130 automatically extends to both sides, thereby adjusting the pressing length of the pressing plate assembly 130.

[0047] refer to Figure 1-Figure 4 The adjusting mechanism 300 is used to adjust the height of the top plate 120 before pressing the material according to the width of the heated part of the plate of the molding machine, and then adjust the descending distance of the top plate 120 when pressing the material next, and indirectly automatically adjust the extension length of the pressing plate assembly 130. The adjusting mechanism 300 is installed on the long side fixing seat 400 and is connected to the driving mechanism 200. When the plate is conveyed to the heating position and the adjusting mechanism 300 is squeezed on both sides, the adjusting mechanism 300 is driven to work, and the driving mechanism 200 is automatically driven to work, driving the top plate 120 away from the base 110, and adjusting the height of the top plate 120. Adjustment is performed, and then when the molding machine heats part of the plate and transmits it to a fixed position, both sides of the plate squeeze the adjustment mechanism 300, and then the adjustment mechanism 300 works, driving the driving mechanism 200 to work. When the driving mechanism 200 works, it drives the top plate 120 to move upward, and then the distance between the top plate 120 and the base 110 is adjusted, so that when pressing the material, the downward moving distance of the top plate 120 is adjusted, and the extension distance of the pressing plate assembly 130 is indirectly adjusted automatically, so that the pressing length of the pressing plate assembly 130 is automatically adjusted according to the width of the plate.

[0048] In this embodiment, the specific use process is as follows: when the heating part of the sheet material of the molding machine is conveyed to the pressing position by the conveying mechanism, refer to Figure 2 The adjusting mechanism 300 is squeezed on both sides of the plate. The adjusting mechanism 300 drives the driving mechanism 200 to work. When the driving mechanism 200 works, it drives the top plate 120 to move upward, thereby adjusting the height of the top plate 120 before pressing the material, and indirectly adjusting the downward moving distance of the top plate 120 during pressing and the extension length of the pressing plate assembly 130. When the plate is conveyed, refer to Figure 3The driving mechanism 200 works to drive the top plate 120 to move downward. During the downward movement of the top plate 120, the pressing plate assembly 130 automatically extends to both sides, and then the pressing length of the pressing plate assembly 130 is adjusted until the pressing plate assembly 130 completely presses the plate.

The fixed plate assembly 130a is used to press a portion of the plate, and the movable plate assembly 130b is used to press portions of the plate on both sides of the fixed plate assembly 130a after extending.

[0051] In this embodiment, the top of the base 110 and the bottom of the top plate 120 are both provided with limited sliding grooves, so as to make the lower moving plate 130b-1 and the upper moving plate 130b-2 more stable when moving;

[0052] refer to Figure 5 The fixing plate assembly 130a includes a lower fixing plate 130a-1 located at the middle of the top of the base 110 and an upper fixing plate 130a-2 located at the bottom of the top plate 120 and corresponding to the lower fixing plate 130a-1. The lower fixing plate 130a-1 cooperates with the upper fixing plate to press the middle of the short side of the plate.

[0053] refer to Figure 5 The movable plate assembly 130b includes a lower movable plate 130b-1 whose bottom extends to the limiting slide groove at the top of the base 110 and is located at both ends of one side of the lower fixed plate 130a-1, and an upper movable plate 130b-2 whose top extends to the limiting slide groove of the top plate 120 and is located at both ends of one side of the upper fixed plate 130a-2. The lower movable plate 130b-1 and the upper movable plate 130b-2 are used to cooperate with each other after extension to press the two ends of the short side of the plate, and then cooperate with the lower fixed plate 130a-1 and the upper fixed plate to make the short side of the plate pressed more fully.

[0054] Example 3

[0055] Based on Example 2, Figure 1-Figure 5The driving mechanism 200 includes a first driving component 210 installed on one side of the base 110 and driving the top plate 120 to move up and down during operation, and a second driving component 220 that automatically drives the two groups of upper movable plates 130b-2 and the two groups of lower movable plates 130b-1 to move away from each other when the top plate 120 moves downward. The first driving component 210 is used to drive the top plate 120 to move downward during the pressing operation, thereby making the fixed plate components 130a and the extension plate components approach each other, clamping and fixing the upper and lower surfaces of the plate. The second transmission component is used to automatically drive the two groups of upper movable plates 130b-2 and the two groups of lower movable plates 130b-1 to move away from each other when the top plate 120 moves downward, thereby extending the pressing length of the entire pressing plate assembly 130, thereby automatically adjusting the pressing length during the pressing process.

The driving motor 210a is used to drive the first threaded rod 210b to rotate during operation, and the first threaded rod 210b is used to drive the top plate 120 to move up and down along the limiting slide bar 210c and the first threaded rod 210b under the limiting action of the limiting slide bar 210c during rotation. The limiting slide bar 210c is used to limit the top plate 120, so that the top plate 120 rotates synchronously when the first threaded rod 210b on the surface rotates, thereby causing the top plate 120 to be unable to move up and down.

[0057] In this embodiment, reference Figure 1-Figure 5 A sawtooth plate 110a extending upward is provided on one side of the base 110, which is used to drive the transmission gear 220b to rotate when the top plate 120 moves up and down;

The screw rod 220a is used to drive the two upper movable plates 130b-2 to move closer to or away from each other when rotating. The transmission gear 220b is used to drive the second pulley 220b-1 to rotate when rotating. A first pulley 220a-1 is provided at one end of the screw rod 220a, which is used to drive the screw rod 220a to rotate when rotating. The side wall of the transmission gear 220b is connected to a second pulley 220b-1 connected to the first pulley 220a-1 by a belt through a rotating shaft, which is used to rotate When the first pulley 220a-1 is driven to rotate, the two upper movable plates 130b-2 are respectively threadedly connected to the two ends of the screw rod 220a, and then when pressing the material, when the top plate 120 moves downward, it drives the transmission gear 220b to move downward. Under the driving action of the serrated plate 110a, the transmission gear 220b rotates during the downward movement, thereby driving the second pulley 220b-1 to rotate. When the second pulley 220b-1 rotates, it drives the first pulley 220a-1 to rotate. When the first pulley 220a-1 rotates, it drives the screw rod 220a to rotate. The rotation of the screw rod 220a drives the two upper movable plates 130b-2 to move away from each other, thereby automatically adjusting the pressing length.

[0060] In this embodiment, reference Figure 1-Figure 6 The top of the top plate 120 is provided with a strip groove 120b that penetrates the top plate 120, so that when the top plate 120 moves downward, the connecting rod 130b-11 passes through the upper moving plate 130b-2 and then passes through the strip groove 120b, so that the top plate 120 can be smoothly lowered;

The elastic member 330a-1 is used to reset the elastic member 330a-1 after the heating of the plate is completed, so that the extrusion plate 330a is reset and moved out of the receiving groove 310a, thereby facilitating the next pressing and heating work.

[0067] In this embodiment, connecting pieces (not shown in the figure) are provided on the rotating shaft connected to the output end of the drive motor 210a and the first bevel gear 210a-1, on the rotating shaft connected to the second bevel gear 210a-11 and the third pulley 210a-111, and on the rotating shaft connected to the threaded cylinder 320a and the fourth pulley 320b. The connecting piece on the rotating shaft connected to the output end of the drive motor 210a and the first bevel gear 210a-1 is used to prevent the second bevel gear 210a-11 from driving the first bevel gear 210a-1 to rotate, thereby preventing the first bevel gear 210a-1 from rotating to generate a force that drives the drive motor 210a to rotate, causing the entirety to get stuck. The connecting piece on the rotating shaft connected to the second bevel gear 210a-11 and the third pulley 210a-111 is used to prevent the drive motor 210a from driving the first bevel gear 210a-1 to rotate. When the bevel gear 210a-1 rotates, thereby driving the first threaded rod 210b to rotate, the second bevel gear 210a-11 is indirectly driven to rotate and drive the third pulley to rotate, thereby preventing the third pulley 210a-111 from rotating and driving the fourth pulley 320b to rotate, and then driving the threaded barrel 320a to rotate and drive the threaded rod and the extrusion plate 330a to move outward, thereby causing the whole to be stuck under the extrusion of the side wall of the plate. The connecting piece on the rotating shaft connecting the threaded barrel 320a and the fourth pulley 320b is used to prevent the elastic member 330a-1 from resetting, and when driving the threaded barrel 320a to reverse, the fourth pulley 320b is driven to rotate, thereby indirectly driving the first threaded rod 210b to reverse and make the top plate 120 move downward, thereby affecting the adjustment of the height of the top plate 120 during the next pressing.

[0068] The connecting piece comprises a ratchet connecting seat with a ratchet groove on its side wall and a ratchet located in the ratchet groove and with a plurality of elastic pawls evenly arranged on its outer side wall along the circumferential direction.
