Description

Technical Field

[0001] This utility model belongs to the field of sandwich box processing technology, specifically relating to a stacking support mechanism based on sandwich packaging box production. Background Technology

[0002] In the food packaging manufacturing industry, sandwich boxes, as common ready-to-eat food packaging containers, require multiple processes including injection molding, stacking and sorting, and subsequent processing. Among these, the stacking process is a crucial step connecting production and packaging, directly affecting the efficiency of subsequent packing and the stability of product transportation.

[0003] In existing technologies, the stacking of sandwich boxes largely relies on automated transport and robotic arms, but several technical challenges remain in actual production. First, different specifications of sandwich boxes (e.g., variations in size and height) require different support structures. Traditional fixed-spacing support devices struggle to adapt to diverse production needs, and frequent tooling changes increase downtime and reduce production efficiency. Second, the stability of the sandwich boxes during stacking is crucial, given their triangular shape and inability to stand independently. Insufficient support or positioning errors can lead to box tilting, misalignment, and deformation due to collisions, increasing scrap rates. Furthermore, existing support structures offer limited adjustment flexibility. While some devices can roughly adjust support spacing, they lack precise positioning and rapid locking mechanisms, resulting in lengthy adjustment processes. Additionally, the reliability of support component reset and locking is insufficient, leading to loosening after repeated reciprocating motions and decreased support accuracy. For stacked sandwich boxes, poorly coordinated unloading after stacking can cause boxes to tip over due to improper timing of support structure removal, further impacting production continuity. To address the aforementioned issues, there is an urgent need for a stacking support mechanism based on sandwich packaging box production that is flexibly adjustable, adaptable to various specifications, provides stable support, and ensures smooth unloading. This mechanism would overcome the shortcomings of existing equipment in terms of versatility, stability, and efficiency, and meet the high-efficiency and flexible production needs of the food packaging industry. Utility Model Content

[0004] This utility model provides a stacking support mechanism based on sandwich packaging box production, which aims to solve the problem that existing stacking support mechanisms based on sandwich packaging box production cannot provide stable support for sandwich box stacks, resulting in stacked sandwich boxes easily swaying left and right and becoming scattered.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a stacking support mechanism based on sandwich packaging box production, comprising:

[0006] Mounting plates are symmetrically arranged on both sides of the rack of the transmission component;

[0007] Guide sleeves are symmetrically provided on both the left and right sides of the top of the mounting plate;

[0008] An adjusting column is slidably installed on the guide sleeve;

[0009] A locking screw is screwed onto the guide sleeve. The locking screw is used to lock the adjusting column.

[0010] A crossbar is installed between the upper parts of the two adjusting columns on the left side, and a horizontal slot is opened in the middle of the crossbar.

[0011] Support rods, multiple support rods are slidably set in the slot of the cross frame by sliding blocks, and two adjacent support rods form a support rod group to support the two sloping side walls at the bottom of the sandwich box;

[0012] Locking assembly: A locking assembly for securing the support rod is provided on the crossbar;

[0013] Connecting plates are provided on the upper part of the side walls of the two adjusting columns on the right side;

[0014] The support assembly is located between the two connecting plates to support the support rod. The support assembly can rotate, and the transmission assembly will transport the stacked sandwich boxes.

[0015] Preferably, the locking assembly includes:

[0016] A straight screw rod is provided on the top of the crossbar, with a slotted hole that is connected to a slotted groove. A straight screw rod is provided on the sliding block at the end of the support rod, and the straight screw rod passes through the slotted hole.

[0017] A wing nut, which screws into a straight screw.

[0018] Preferably, the support component includes:

[0019] Square blocks are provided at the near ends of the two connecting plates;

[0020] A rotating shaft is rotatably installed in the center of the square block on the front side;

[0021] The support block has a square groove on the lower front side of the rear square block, and the support block is rotatably mounted on the rotating shaft.

[0022] The driving component is provided on the side wall of the front connecting plate. The driving component is used to drive the support block to rotate around the rotation axis.

[0023] The support block has a locking block at its rear end, which engages with the square groove.

[0024] Preferably, the driving component includes:

[0025] A fixing plate is provided on the right side wall of the front connecting plate;

[0026] An electric actuator is mounted on a fixed plate in a rotating manner, and the actuator rod is rotatably connected to the front end of the support block.

[0027] Preferably, it also includes a stop block. A stop block is provided on the left side of the square groove of the square block. The presence of the stop block can limit the position of the locking block on the support block.

[0028] Preferably, it also includes a ball catcher, with a ball groove on the right side of the block and a ball catcher on the left side wall of the block. The ball catcher cooperates with the ball groove, and the ball catcher can lock the support block when it is inserted into the ball groove.

[0029] Preferably, it also includes anti-slip blocks, with anti-slip blocks symmetrically arranged at the lower right end of the support rod to increase the contact surface with the support block and play an anti-slip role.

[0030] Preferably, the top left side of the support block has an inclined surface, which can guide the slightly inclined support rod on the right side, and can quickly complete the matching support of the support rod.

[0031] Preferably, the top of the support block has a rough surface to prevent the right end of the support rod from sliding on the top of the support block when the sandwich box is placed by the stacking machine, which would cause the sandwich box to swing.

[0032] Preferably, the support rod is made of smooth stainless steel, which facilitates smoother movement of the sandwich box by the conveyor belt of the transmission component.

[0033] As can be seen from the above technical solution, in this utility model:

[0034] 1. Addressing the issue of traditional fixed-spacing support devices being difficult to adapt to sandwich boxes of different sizes, this structure achieves flexible adaptation through a dual adjustment mechanism: Firstly, the adjusting column can slide up and down along the guide sleeve and be fixed by the locking screw, allowing for quick adjustment of the height distance between the support rod assembly and the conveyor belt to accommodate sandwich boxes of different heights; secondly, the support rod slides within the slot of the crossbeam via a sliding block, and in conjunction with the locking assembly, the spacing between adjacent support rods can be precisely adjusted, and after adjustment, it can be quickly locked by a straight screw and a wing nut. This allows for adaptation to sandwich boxes of different sizes without changing tooling.

[0035] 2. To address issues such as box tilting, stacking misalignment, and decreased support accuracy during stacking, the structure employs multiple design features to ensure stability: the support rod assembly is securely fixed by locking components to prevent sliding and displacement; the top of the support block of the support component has a rough surface to enhance contact friction with the support rod, and during resetting, the locking block engages with the square groove, and the locking ball locks with the ball groove, ensuring precise support positioning and preventing loosening; anti-slip blocks on both sides of the support rods can laterally limit the sandwich box, preventing it from wobbling during stacking. These multiple stabilizing structures reduce problems such as box tilting and collision deformation. Attached Figure Description

Detailed Implementation

[0045] To make the technical problems, technical solutions, and beneficial effects 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.

[0046] Implementation, for example Figures 1-4 As shown, the stacking support mechanism based on sandwich packaging box production includes a mounting plate 4, a guide sleeve 5, an adjusting column 6, a locking screw 7, a crossbar 8, a support rod 9, a locking assembly 10, a connecting plate 11, and a support assembly 12. The mounting plate 4 is symmetrically installed on both sides of the frame of the transmission assembly 1 by bolt connection. The top of the mounting plate 4 is symmetrically installed on both the left and right sides. The adjusting column 6 is slidably installed on the guide sleeve 5. The locking screw 7 is screwed onto the guide sleeve 5 and is used to lock the adjusting column 6. The crossbar 8 is installed between the upper parts of the two adjusting columns 6 on the left side. A slot is opened horizontally in the middle of the crossbar 8. Multiple support rods 9 are slidably installed in the slot of the crossbar 8 by sliding blocks.

[0047] Two adjacent support rods 9 form a support rod group 9 for supporting the two sloping side walls at the bottom of the sandwich box. The support rods 9 are made of smooth stainless steel, which facilitates smoother movement of the sandwich box by the conveyor belt of the transmission component 1. A locking component 10 for fixing the support rods 9 is provided on the cross frame 8. The locking component 10 includes a straight screw 102 and a wing nut 103. A slotted hole 101 is opened at the top of the cross frame 8, which is connected to a slot. A straight screw 102 is provided on the sliding block at the end of the support rod 9. The straight screw 102 passes through the slotted hole 101. The wing nut 103 is screwed into the straight screw 102. A connecting plate 11 is provided on the upper part of the adjacent side wall of the two adjusting columns 6 on the right side. A support component 12 for supporting the support rods 9 is provided between the two connecting plates 11. The support component 12 can rotate.

[0048] The transmission component 1 transports the stacked sandwich boxes. The support component 12 includes a square block 121, a rotating shaft 122, a support block 124, and a drive component 125. A square block 121 is provided at one end of each of the two connecting plates 11. The rotating shaft 122 is rotatably mounted in the center of the front square block 121, and a square groove 123 is formed in the lower front part of the rear square block 121. A support block 124 is rotatably mounted on the rotating shaft 122. The top left side of the support block 124 has an inclined surface, which guides the slightly inclined support rod 9 on the right side, enabling quick and easy support of the support rod 9. The top of the support block 124 has a rough surface to prevent damage when the sandwich boxes are placed in the stacking machine 3. The right end of the support rod 9 slides on the top of the support block 124, causing the sandwich box placed there to swing. A driving member 125 is provided on the side wall of the front connecting plate 11. The driving member 125 includes a fixed plate 1251 and an electric push rod 1252. The right side wall of the front connecting plate 11 is provided with a fixed plate 1251. The electric push rod 1252 is rotatably mounted on the fixed plate 1251. The push rod of the electric push rod 1252 is rotatably connected to the front end of the support block 124. The driving member 125 is used to drive the support block 124 to rotate around the rotating shaft 122. A locking block 126 is provided at the rear end of the support block 124. The locking block 126 cooperates with the square groove 123.

[0049] like Figure 5 , Figure 6 and Figure 7 As shown, it also includes a stop block 13, a ball catcher 15, and an anti-slip block 16. The stop block 13 is provided on the left side of the square groove 123 of the square block 121, and a ball groove 14 is opened on the right side of the stop block 13. A ball catcher 15 is provided on the left side wall of the block catcher 126. The ball catcher 15 cooperates with the ball groove 14. Anti-slip blocks 16 are symmetrically provided on the lower right end of the support rod 9.

[0050] The strip conveyor assembly 2 is located in the front-to-back direction for conveying, the stacking machine 3 is located at the left rear of the strip conveyor assembly 2, the transmission assembly 1 is located at the lower part of the strip conveyor assembly 2 and conveys in the left-to-right direction, and the sandwich box stacking support structure is located at the top left of the transmission assembly 1 and below the stacking machine 3. The strip conveyor assembly 2, the stacking machine 3 and the transmission assembly 1 are all existing technologies and have corresponding control systems. During operation, the strip conveyor assembly 2 conveys the injection-molded sandwich box plastic parts to the stacking machine 3.

[0051] The position sensor of the stacking machine 3 detects the sandwich box and sends a signal to the control system. The control system then sends a command to the strip conveyor assembly 2 and the downward movement system of the stacking machine 3. The power element of the strip conveyor assembly 2 shuts down to stop the backward transmission of the sandwich box plastic parts. The downward movement system of the stacking machine 3 drives the pneumatic clamp to move down, thereby causing the pneumatic clamp to extend into the sandwich box directly below and perform adsorption. Then, it drives the sandwich box to continue moving downward and place it between the corresponding support rods 9 on the transmission assembly 1. The bottom of the sandwich box contacts the transmission belt of the transmission assembly 1. The pneumatic clamp of the stacking machine 3, which has been reset, is released, and the downward movement system of the stacking machine 3 is driven to reset.

[0052] The stacking machine 3 and the strip conveyor assembly 2 work together to continuously move the stacking machine 3 to unload the sandwich boxes from the plastic parts of the sandwich boxes that are sequentially conveyed by the strip conveyor assembly 2, and stack them on top of the sandwich boxes on the support rod 9. When the entire sandwich box plastic part is unloaded, the operator controls the electric push rod 1252 to extend. The electric push rod 1252 drives the support block 124 to swing to the right around the rotating shaft 122. When the support block 124 rotates 90°, the right side of the support rod 9 is suspended in the air. The power element of the transmission assembly 1 is activated. Then the control system sends a command to the power element of the transmission assembly 1, and the conveyor belt moves to the right, which in turn moves the bottom end of the sandwich box that is in contact with it to the right. The stacked sandwich boxes slide to the right along the support rod 9, and then the sandwich boxes are separated from the support rod 9 and conveyed into the collection box by the conveyor belt.

[0053] When there is no sandwich box on the support rod 9, the operator controls the electric push rod 1252 to shorten, thereby driving the support block 124 to reset. Due to the presence of the stop block 13, the locking block 126 on the support block 124 can play a limiting role. The locking ball 15 can lock the support block 124 by locking into the ball groove 14. Since the top left side of the support block 124 is inclined, the support block 124 can guide the slightly inclined support rod 9 on the right side when resetting, and can quickly complete the matching support of the support rod 9. The anti-slip blocks 16 on both sides of the support rod 9 can play a limiting role to prevent the support rod 9 from shifting when supporting the sandwich box.

[0054] When sandwich boxes of different sizes need to be supported, the operator loosens the locking screw 7, then adjusts the position of the adjusting column 6 up or down, and then tightens the adjusting column 6 again by tightening the locking screw 7. By rotating the wing nut 103, the crossbar 8 is no longer compressed. The distance between the two adjacent support rods 9 is adjusted by the straight screw 102. The crossbar 8 is then locked by tightening the wing nut 103 and the straight screw 102. By adjusting the distance between the two adjacent support rods 9 and the height from the conveyor belt of the transmission assembly 1, sandwich boxes of different sizes can be supported and stably fixed within the support rod 9 group.

[0055] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
