Description

Technical Field

[0001] This utility model relates to an adaptive high and low stack shaping device, belonging to the field of packaging machinery. Background Technology

[0002] In the packaging industry, shaping machines are usually set at the rear of the production line to shape and degas the stacks of materials that are about to come off the line. In ton bag packaging production lines, in order to facilitate storage and loading after coming off the line, ton bags are often required to be stacked before coming off the line. Patent document CN223673013U discloses a fully automatic shaping machine. The inlet and outlet of the shaping machine frame are equipped with liftable shaping plates, and the upper part of the frame is equipped with a top plate. In the initial position, the inlet shaping plate is at the top of the frame. After the ton bag is sent into the frame by the conveyor, the inlet shaping plate is lowered to the low position. The cylinder drives the top plate to press down on the ton bag. At the same time, the shaping plates on all four sides are driven by the cylinder to squeeze the bag body to form a five-sided shaping. After shaping, it is transferred off the line. The aforementioned shaping machine is limited by the top plate stroke and can only adapt to stacks of materials with small height changes. In addition, the purpose of raising the inlet and outlet shaping plates to a high position is to avoid stacks of materials entering the shaping area. When the height of the stack is high, the height of the inlet and outlet shaping plates also needs to be increased, and their lifting stroke needs to be increased accordingly, which will cause the shaping device to occupy a large vertical space. When two ton bags are stacked, the height of the stack increases significantly. Therefore, the existing shaping machine cannot adapt to the shaping needs of stacked bags. Utility Model Content

[0003] To address the problem that existing shaping machines cannot simultaneously shape high and low stacks, this invention proposes an adaptive high and low stack shaping device. It includes a stack conveyor and a four-column enclosed frame. The stack conveyor passes through the frame along the front-to-back conveying direction. Two sets of shaping mechanisms are symmetrically arranged on the left and right sides of the frame. Rotary doors are provided at both the front and rear ends of the frame and are rotatably connected to them. The rotating doors are equipped with shaping mechanisms and can open and close in the front-to-back direction. When closed, the rotating doors can be locked to the frame; when open, they can avoid incoming and outgoing stacks. A top plate mechanism is provided at the top of the frame, connected to the traction end of a lifting mechanism and driven by the lifting mechanism to achieve lifting. The lifting mechanism is located at the top of the frame. The top plate mechanism includes a moving frame and a top pressure plate. The moving frame is equipped with a locking unit that can lock the moving frame at different height positions. The top pressure plate can be independently raised and lowered when the moving frame is locked. The shaping mechanism includes two sets of shaping plates arranged vertically. Each set of shaping plates has an independent drive mechanism on its outer side, which can drive the shaping plates to move horizontally.

[0004] The upper four corners of the mobile frame are connected to the traction end of the lifting mechanism. The mobile frame is driven by the lifting mechanism to move up and down along the vertical guide rail on the frame. A horizontally arranged top pressure plate is provided in the lower middle part of the mobile frame. The upper end of the top pressure plate is hinged to the cylinder rod of a vertically arranged downward pressure cylinder. The cylinder body of the downward pressure cylinder is connected to the mobile frame. The downward pressure cylinder drives the top pressure plate to move up and down vertically.

[0005] Locking units are provided at the four corners of the side of the movable frame. Each locking unit includes a locking block. The middle part of the locking block is hinged to the movable frame, and the upper part of the locking block is hinged to the cylinder rod of the locking cylinder. The cylinder body of the locking cylinder is hinged to the movable frame. A limiting block is provided at the non-locking end of the locking block. Toothed positioning plates that cooperate with the locking block are provided at the four corners of the outer side of the frame. Multiple sets of stepped positioning slots are continuously opened along the height direction of the toothed positioning plates. The stepped positioning slots of different heights correspond to different lowering and locking positions of the movable frame. The locking cylinder drives the locking block to rotate up and down around the hinge point. After rotating to the position, the locking end of the locking block abuts and engages with a set of stepped positioning slots, and the non-locking end abuts with the limiting block to achieve positioning and locking.

[0006] The area between the two sets of shaping plates arranged vertically is provided with vertically arranged bearing rods.

[0007] Rotary cylinders are respectively installed in the middle of the front and rear ends of the frame. The cylinder rod of the rotary cylinder is hinged to the middle of the revolving door. The rotary cylinder drives the revolving door to realize the opening and closing action.

[0008] A buffer frame is provided on the outside of the frame, near the rotating end of the rotating door and located outside the material stack conveyor. When the rotating door is in the open state, its outer wall flexibly abuts against the buffer frame.

[0009] A swing stop block that can swing horizontally back and forth is hinged to the frame near the free end of the revolving door. When the revolving door is closed, the swing stop block swings to its end face against the outer wall of the revolving door to achieve a limiting stop.

[0010] The beneficial effects of this utility model are:

[0011] A. Both the rotating door and the frame are equipped with two sets of shaping plates arranged vertically. The horizontal movement of each shaping plate can be controlled according to the height of the stack. The actions are independent and do not interfere with each other, so that the same shaping device can adapt to stacks with large height differences to form continuous shaping.

[0012] B. The top plate mechanism is liftable and equipped with a locking unit, which can automatically adjust the lifting height according to the height of the material stack and lock it at the corresponding height by the locking unit. During the shaping operation, the lifting mechanism does not need to continuously bear the reverse load of the top plate.

[0013] C. The revolving door mechanism at the entrance and exit reduces the required height space of the equipment, and the overall equipment has a high degree of integration, enabling it to be compatible with the shaping operations of high and low stacks in a limited space.

Detailed Implementation

[0022] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the embodiments of this utility model are described in detail below with reference to the accompanying drawings. The embodiments are exemplary and intended to explain this utility model, but should not be construed as limiting this utility model.

[0023] like Figure 1As shown, the purpose of this utility model is to provide an adaptive high and low stack shaping device, which includes a stack conveyor 1, a four-column enclosed frame 2, a rotating door 3, a shaping mechanism 4, a top plate mechanism 5, and a lifting mechanism 6. The stack conveyor 1 is installed inside the frame 2 along the front and rear conveying direction and is used for conveying and feeding the stack to be shaped and discharging it after shaping. Two sets of shaping mechanisms 4 are symmetrically arranged on the left and right sides of the frame 2. The front and rear ends of the frame 2 are equipped with rotating doors 3 and are rotatably connected to them. The rotating doors 3 are equipped with shaping mechanisms 4. The rotating doors 3 can realize the opening and closing action in the front and rear directions. When the rotating doors 3 are in the closed state, they can be locked with the frame 2. When the rotating doors 3 are in the open state, they can avoid the stacks entering and exiting. The top plate mechanism 5 is provided on the upper part of the frame 2. The top plate mechanism 5 is connected to the traction end of the lifting mechanism 6. The lifting mechanism 6 is located at the top of the frame 2 and drives the top plate mechanism 5 to realize the vertical lifting action.

[0024] like Figure 2 As shown, in one embodiment, the top plate mechanism 5 includes a movable frame 52 and a top pressure plate 51. The four upper corners of the movable frame 52 are connected to the traction end of the lifting mechanism 6. The lifting mechanism 6 preferably uses a chain lifting drive assembly. Guide wheels are provided at the four corners of the movable frame 52. Vertical guide rails 21 that cooperate with the guide wheels are arranged at the four corners of the frame 2. The lifting mechanism 6 drives the movable frame 52 to move up and down along the vertical guide rails 21. A horizontally arranged top pressure plate 51 is provided at the lower center of the movable frame 52. The upper end of the top pressure plate 51 is hinged to the cylinder rod of a vertically arranged downward pressing cylinder 53. The cylinder body of the downward pressing cylinder 53 is connected to the movable frame 52. The downward pressing cylinder 53 drives the top pressure plate 51 to move vertically up and down.

[0025] like Figure 2 , Figure 3As shown, in one embodiment, locking units are provided at the four corners of the side of the movable frame 52. Each locking unit includes a locking block 54, a locking cylinder 55, and a limiting block 56. The middle part of the locking block 54 is hinged to the movable frame 52, and the upper part of the locking block 54 is hinged to the cylinder rod of the locking cylinder 55. The cylinder body of the locking cylinder 55 is hinged to the movable frame 52. The non-locking end of the locking block 54 is provided with a limiting block 56. Toothed positioning plates 22 are provided at the four corners of the outer side of the frame 2. The toothed positioning plates 22 have multiple sets of equidistant stepped slots 23 continuously opened along the height direction. The stepped slots 23 of different heights correspond to different lowering and locking positions of the top plate mechanism 5. The locking cylinder 55 drives the locking block 54 to rotate up and down around the hinge point. When the top plate mechanism descends to the appropriate height of the material stack, the locking cylinder 55 engages the locking cylinder. The cylinder 55 extends to drive the locking block 54 to rotate downwards. After rotating into position, the locking end of the locking block 54 abuts against and engages with the stepped slot 23 at the corresponding height, while the non-locking end abuts against the limiting block 56. When the top plate 51 is working, it is rigidly locked by the engagement of the limiting block 56 and the locking block 54, so that the lifting mechanism 6 does not need to continuously bear the reverse load of the top plate 51. When it is necessary to adjust the height of the top plate 51, the moving frame 52 is first driven by the lifting mechanism 6 to descend vertically a short distance, so that the locking end of the locking block 54 is disengaged from the original engagement position with the stepped slot 23, which facilitates the upward swing of the locking block 54. Then, the locking cylinder 55 drives the locking block 54 to swing upwards, so that the locking block 54 is completely disengaged from the stepped slot 23 to complete the unlocking. The lifting mechanism 6 can then drive the top plate mechanism 5 to adjust the height.

[0026] like Figure 1 , Figure 4 As shown, in one embodiment, rotary cylinders 9 are respectively provided at the middle of the front and rear ends of the frame 2. The cylinder rod of the rotary cylinder 9 is hinged to the middle of the rotating door 3. The rotary cylinder 9 drives the rotating door 3 to realize the opening and closing action. A buffer frame 7 is provided on the outside of the frame 2, near the rotating end of the rotating door 3 and located outside the material stack conveyor 1. When the rotating door 3 is in the open state, its outer wall flexibly abuts against the buffer frame 7. The buffer on the buffer frame 7 absorbs the impact load during the door panel movement, avoiding hard collisions between rigid parts. The frame near the free end of the rotating door 3 is... 2. The upper hinged swing stop block 8 is provided with two swing stop blocks 8 at intervals. The swing stop block 8 is driven by a cylinder to achieve horizontal swinging action. When the rotating door 3 is closed in place, the cylinder drives the swing stop block 8 to swing until its end face abuts against the outer wall of the rotating door 3 to achieve limit stop and form rigid lock. It can resist the pushing force of the material stack on the door panel during the shaping operation and ensure that a stable and sealed shaping operation space is formed inside the frame 2. When it is necessary to open the rotating door 3, the cylinder drives the swing stop block 8 to disengage from the rotating door 3 to unlock, and the door opening action can be completed by rotating cylinder 9.

[0027] like Figure 5As shown, in one embodiment, the shaping mechanism 4 includes two sets of shaping plates 41 arranged vertically. Each set of shaping plates 41 has an independent drive mechanism 42 on its outer side. The drive mechanism 42 can drive the shaping plate 41 to move horizontally. The area between the upper and lower sets of shaping plates 41 is provided with vertically arranged pressure rods 43. The pressure rods 43 can effectively offset the lateral extrusion force and ensure the flatness of the side surface during the extrusion shaping of the material stack. Furthermore, the drive mechanism 42 preferably uses an electro-hydraulic push rod, which has strong heavy-duty extrusion capacity, stepless adjustment of output pressure, and pressure maintenance throughout the extrusion process, making the shaped stack more square and less prone to rebound and collapse. In actual use, the electro-hydraulic push rod can push out the lower shaping plate 41 separately or push out the upper and lower shaping plates 41 together, depending on the actual height of the material stack. This can adapt to material stacks with large height differences, making the shaping device highly versatile. Only one such device needs to be equipped on the production line to complete the shaping operation of material stacks with different heights, solving the problem of shaping high and low stacks in a compatible manner.

[0028] like Figures 1 to 7 The following diagram illustrates the working principle of this embodiment:

[0029] With the rotating door 3 in the open state, the ton bag is transferred into the middle position of the frame 2 by the stack conveyor 1. The lifting mechanism 6 drives the top plate mechanism 5 to move and adjust its position to a suitable height for the stack. The locking cylinder 55 drives the locking block 54 to rotate downward. The locking block 54 contacts the toothed positioning plate 22 and finally abuts and locks in the stepped locking groove 23. At the same time, the rotating cylinder 9 drives the rotating door 3 to close. The rotating door 3 is locked after the swing stop block 8 swings, forming a closed shaping area. The pressing cylinder 53 drives the top pressing plate 51 to descend vertically and squeeze the top of the bag. At the same time, the extension state of the upper and lower shaping plates 41 is judged according to the height of the stack, and the drive mechanism 42 that needs to work is controlled to drive the corresponding shaping plate 41 to move horizontally and squeeze the bag body. Together, the stack is squeezed from five sides to expel the air inside the ton bag and complete the stack shaping.
