Description

Technical Field

[0001] This utility model relates to the field of flattening machine structure technology, and in particular to an adjustment and positioning component for a flattening machine. Background Technology

[0002] After the corrugated cardboard printing process is completed, in order to prevent the corrugated cardboard from being squeezed and folded during transportation, it is generally necessary to stack the corrugated cardboard on the pressing platform to ensure the flatness of the corrugated cardboard.

[0003] When stacking corrugated cardboard, manual support and positioning by workers are required. After stacking, misalignment is common. During transfer after stacking, this misalignment and dragging can cause the cardboard to tilt and fall, resulting in collisions and damage, affecting subsequent processing. Therefore, an adjustment and positioning component for the flattening machine is needed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustment and positioning component for a flattening machine includes a base, a flattening frame mounted on the top of the base, a pressing component movably mounted inside the flattening frame, an adjustment component mounted on the surface of the base via a groove, the adjustment component including pulleys, the pulleys being equidistantly mounted on the surface of the base via through slots, a support frame placed in the groove of the base, and a first cylinder connected to the center of the bottom end of the support frame, the first cylinder penetrating the base and being fixed to the surface of a suspension plate, the suspension plate being fixed to the bottom end of the base, and positioning accessories provided on the left and right sides of the bottom end of the flattening frame.

[0007] Preferably, the positioning accessory includes a second cylinder, the output end of which passes through a through hole through the flattening frame and is connected to a positioning plate. The positioning plate is moved by extending and retracting the output end of the second cylinder, and the positioning plate can support and push the corrugated cardboard during displacement.

[0008] Preferably, the support frame has a hollowed-out groove on its surface, and the position of the hollowed-out groove is adapted to the pulley. The pulley passes through the support frame to support the corrugated cardboard, which facilitates the rolling of the pulley to push and move it.

[0009] Preferably, positioning rods are connected at the four corners of the bottom of the support frame, and the positioning rods pass through the inside of the base through through holes. The end of the positioning rod is threaded with a threaded sleeve, and the positioning rod is positioned through the through holes of the base to ensure the stability of the support frame when moving up and down.

[0010] Preferably, the pressing assembly includes two movable blocks, which are inserted into the flattening frame through guide grooves. One of the movable blocks is threaded onto the surface of a threaded rod. The top end of the threaded rod passes through the flattening frame and is connected to a drive motor. The two movable blocks are connected and fixed together by a beam plate. An auxiliary support component is installed at the bottom end of the beam plate. The threaded rod can control the movement of the movable blocks within the guide groove of the flattening frame, thereby adjusting the suspension position of the beam plate.

[0011] Preferably, the auxiliary support component includes a hydraulic cylinder, the output end of which is connected to a pressure plate, and a rubber pad is installed in the bottom end of the pressure plate through a groove. The pressure plate can move smoothly up and down by moving through the through hole of the hanging plate via a positioning shaft.

[0012] Preferably, a positioning shaft is connected to the four corners of the top of the pressure plate, and the positioning shaft passes through the inside of the hanging plate through a through hole. The hanging plate is connected and fixed to the beam plate. The positioning shaft is fitted with an elastic accessory, which consists of two nut ends and one spring end, and can provide elastic support for the movement of the pressure plate.

[0013] This utility model has at least the following beneficial effects:

[0014] 1. By setting an adjustment component, the device achieves auxiliary and stable unloading of corrugated cardboard. Compared with the traditional structure, this device moves the support frame by retracting the output end of the first cylinder, so that the support frame moves the stacked corrugated cardboard onto the pulley surface. This facilitates the conveying and unloading of the flattened corrugated cardboard by the pulley, ensuring the smoothness of unloading and avoiding damage caused by the stacked corrugated cardboard tilting and falling due to dragging.

[0015] 2. By setting positioning accessories, the device can achieve upright support for stacked cardboard. The corrugated cardboard is placed on the support frame surface, and the output end of the second cylinder moves to push the positioning plate. The movement of the positioning plate can push the sides of the stacked corrugated cardboard to ensure the stability of the stacked corrugated cardboard and reduce the probability of misalignment of the stacked corrugated cardboard. At the same time, the positioning plate retracts and moves to fit against the inner wall of the flattening frame to avoid the positioning plate obstructing the movement of the auxiliary support components.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] Reference Figure 1-4 An adjustment and positioning component for a flattening machine includes a base 1, a flattening frame 2 mounted on the top of the base 1, a pressing component 3 movably mounted inside the flattening frame 2, an adjustment component 4 mounted on the surface of the base 1 through a groove, the adjustment component 4 including pulleys 46, the pulleys 46 being equidistantly mounted on the surface of the base 1 through through slots, a support frame 41 placed in the groove of the base 1, and a first cylinder 42 connected to the center of the bottom end of the support frame 41, the first cylinder 42 passing through the base 1 and fixed to the surface of a suspension plate 43, the suspension plate 43 being fixed to the bottom end of the base 1, and positioning accessories 5 provided on the left and right sides of the bottom end of the flattening frame 2.

[0024] The positioning accessory 5 includes a second cylinder 51, and the output end of the second cylinder 51 passes through a through hole through the flattening frame 2 and is connected to a positioning plate 52.

[0025] The support frame 41 has a hollowed-out groove on its surface, and the position of the hollowed-out groove is adapted to the pulley 46.

[0026] Positioning rods 44 are connected at the four corners of the bottom end of the support frame 41, and the positioning rods 44 pass through the inside of the base 1 through the through hole. The end of the positioning rods 44 is threaded with a screw sleeve 45.

[0027] The pressing assembly 3 includes two movable blocks 32, which are inserted into the flattening frame 2 through guide grooves. One of the movable blocks 32 is threaded onto the surface of a threaded rod 33. The top of the threaded rod 33 passes through the flattening frame 2 and is connected to a drive motor 34. The two movable blocks 32 are connected and fixed together by a beam plate 31. An auxiliary support component 35 is installed at the bottom of the beam plate 31.

[0028] The auxiliary support component 35 includes a hydraulic cylinder 356, the output end of which is connected to a pressure plate 353, and the bottom end of the pressure plate 353 is fitted with a rubber pad 354 through a groove.

[0029] Positioning shafts 352 are connected to the four corners of the top of the pressure plate 353, and the positioning shafts 352 pass through the inside of the hanging plate 351 through the through holes. The hanging plate 351 is connected and fixed to the beam plate 31. Elastic accessories 355 are sleeved on the positioning shafts 352.

[0030] When corrugated cardboard is stacked on the surface of support frame 41, the output end of the second cylinder 51 extends and retracts to push the positioning plate 52 to move. The positioning plate 52 supports and pushes the corrugated cardboard during displacement, ensuring the neatness of the cardboard edges. Through the hollow groove design of support frame 41, when support frame 41 moves downwards, pulley 46 passes through support frame 41 to support the corrugated cardboard, facilitating the rolling and pushing of pulley 46 and ensuring smooth movement of the corrugated cardboard. When support frame 41 moves, it can drive positioning rod 44 to move within the through hole of base 1. The through hole of base 1 positions positioning rod 44, ensuring the stability of support frame 41 during vertical movement. A threaded sleeve 45 is threaded onto the end of positioning rod 44, and the threaded sleeve 45 moves on the surface of positioning rod 44. The maximum lifting and lowering distance of the support frame 41 is adjusted. The output end of the drive motor 34 drives the threaded rod 33 to rotate. The threaded rod 33 can control the movable block 32 to move in the guide groove of the flattening frame 2, thereby adjusting the suspension position of the beam plate 31 and improving the controllability of the device. The positioning shaft 352 moves in the through hole of the hanging plate 351, which can ensure the stability of the up and down movement of the pressure plate 353. At the same time, the design of the rubber pad 354 embedded in the bottom end of the pressure plate 353 can reduce the pressure damage to the corrugated cardboard during the downward pressing of the pressure plate 353 and improve the protection effect of the corrugated cardboard under pressure. The elastic accessory 355 consists of two nut ends and one spring end, which can provide elastic support for the movement of the pressure plate 353 and further improve the safety of the pressure plate 353 during downward pressing.

[0031] Working principle: According to the appendix Figure 1 With appendix Figure 4 As shown, during use, corrugated cardboard can be stacked on the surface of the support frame 41. The second cylinder 51 is activated, causing its output end to extend and retract, pushing the positioning plate 52 to move, thus ensuring the neatness of the stacked corrugated cardboard edges. Simultaneously, according to the attached... Figure 2 With appendix Figure 3 As shown, the drive motor 34 can be started, so that the output end of the drive motor 34 drives the threaded rod 33 to rotate. The rotation of the threaded rod 33 can control the displacement of the movable block 32 and adjust the height of the beam plate 31. At the same time, the output end of the hydraulic cylinder 356 extends and retracts to control the movement of the pressure plate 353. The pressure plate 353 cooperates with the rubber pad 354 to press down the stacked corrugated cardboard.

[0032] Secondly, according to the appendix Figure 4 As shown, after flattening, the first cylinder 42 can be started, causing the output end of the first cylinder 42 to retract and drive the support frame 41 to move. The movement of the support frame 41 can drive the positioning rod 44 to move in the through hole of the base 1, so that the support frame 41 is placed on the surface of the base 1, and the pulley 46 passes through the support frame 41 to support the corrugated cardboard, which facilitates the pushing and displacement of the corrugated cardboard.
