Description

Technical Field

[0001] This utility model belongs to the field of food processing technology, and specifically relates to a box-dropping mechanism. Background Technology

[0002] In industries such as food packaging and food processing, it is often necessary to separate and drop stacked food containers one by one for subsequent packaging or filling operations. Traditional container dropping devices typically use simple gravity dropping or mechanical lever separation methods, which have the following problems:

[0003] Double-fall problem: Due to the lack of precise layer control, multiple lunch boxes can easily fall at the same time, affecting the stability of subsequent processes.

[0004] Jamming issue: The edges of the lunchbox can easily get stuck on the lifting structure, causing it to fall unevenly or even damage the lunchbox.

[0005] Poor adaptability: Traditional devices have difficulty adjusting the lifting position for different sizes of lunch boxes, resulting in insufficient compatibility.

[0006] In existing technologies, some improved solutions use electromagnets or complex linkage mechanisms to separate the lunch boxes, but these solutions suffer from problems such as complex structures, high maintenance costs, and slow response speeds.

[0007] Therefore, there is an urgent need for a box-dropping mechanism that is simple in structure, highly reliable, and can accurately control the falling of a single box. Utility Model Content

[0008] In view of this, the main objective of this utility model is to provide a box-dropping mechanism.

[0009] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0010] A box-dropping mechanism, comprising a frame, a lifting mechanism, and a first dropping mechanism;

[0011] The middle position of the frame forms a receiving cavity for accommodating stacked lunch boxes;

[0012] The lifting mechanism is located on the left and right sides of the receiving cavity and is used to control the lifting state of the upper layer of lunch boxes in the stacked lunch boxes.

[0013] The first dropping mechanism is located on the left and right sides of the receiving cavity and below the lifting mechanism, and is used to control the lifting state of the lower layer of lunch boxes in the stacked lunch boxes.

[0014] Preferably, the lifting mechanism includes a cylinder and a first lifting plate; the cylinder is fixedly installed in the frame body, and the first lifting plate is installed on the output end of the cylinder and is engaged with the edge of the lunch box through its lower side.

[0015] Preferably, the lower side of the first support plate is provided with a first arc-shaped curved edge, which is used to engage with the edge of the lunch box to support the lunch box.

[0016] Preferably, the first dropping mechanism includes a cylinder and a first dropping plate; the cylinder is fixedly installed in the frame body, and the first dropping plate is installed on the output end of the cylinder and is engaged with the edge of the lunch box by its upper side.

[0017] Preferably, the upper side of the first dropping plate is provided with a second arc-shaped curved edge, which is used to engage with the edge of the lunch box to support the lunch box.

[0018] Preferably, the lifting mechanism and the first falling mechanism are used to control the lifting state of two adjacent lunch boxes.

[0019] Preferably, it further includes a second dropping mechanism, which is disposed on the front and rear sides of the receiving cavity and is used to control the lifting state of the lower layer of lunch boxes in the stacked lunch boxes.

[0020] Preferably, the second falling mechanism and the first falling mechanism are located at the same horizontal height.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] The box-dropping mechanism provided by this utility model achieves precise layered drop control of stacked lunch boxes through a combination design of a lifting mechanism and a first dropping mechanism. The lifting mechanism with layered control works in conjunction with the first dropping mechanism to reliably support the upper lunch box while releasing the bottom lunch box, ensuring that only one lunch box drops at a time. The symmetrical mechanism structure on the left and right sides ensures that the lunch boxes are subjected to balanced forces. The overall structure is simple and reliable, effectively solving the problems of double dropping or jamming that are prone to occur in traditional box-dropping devices. Attached Figure Description

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.

[0031] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, article, or apparatus that includes that element.

[0032] This utility model embodiment provides a box-dropping mechanism, such as Figure 1-5 As shown, the mechanism includes a frame 1, a lifting mechanism 2, and a first lowering mechanism 3;

[0033] The middle position of the frame 1 forms a receiving cavity for accommodating stacked lunch boxes;

[0034] The lifting mechanism 2 is located on the left and right sides of the receiving cavity and is used to control the lifting state of the upper layer of lunch boxes in the stacked lunch boxes;

[0035] The first falling mechanism 3 is located on the left and right sides of the receiving cavity and below the lifting mechanism 2, and is used to control the lifting state of the lower layer of lunch boxes in the stacked lunch boxes.

[0036] The box-dropping mechanism provided by this utility model achieves precise layered drop control of stacked lunch boxes through the combined design of the lifting mechanism 2 and the first dropping mechanism 3. The lifting mechanism 2 and the first dropping mechanism 3 work together to reliably support the upper lunch box while releasing the bottom lunch box, ensuring that only one lunch box drops at a time. The symmetrical mechanism structure on the left and right sides ensures the balance of force on the lunch boxes. The overall structure is simple and reliable, effectively solving the problems of double dropping or jamming that are prone to occur in traditional box-dropping devices.

[0037] The lifting mechanism 2 includes a cylinder and a first lifting plate 201; the cylinder is fixedly installed inside the frame 1, and the first lifting plate 201 is installed on the output end of the cylinder and is engaged with the edge of the lunch box through its lower side.

[0038] The lower side of the first support plate 201 is provided with a first arc-shaped curved edge 2011, which is used to snap onto the edge of the lunch box to support the lunch box.

[0039] When the cylinder extends, the first arc-shaped curved edge 2011 on the lower side of the first lifting plate 201 engages with the edge of the lunch box to lift the lunch box.

[0040] When the cylinder resets, the first arc-shaped raised edge 2011 of the first lifting plate 201 retracts and moves away from the edge of the lunch box, thus canceling the lifting of the lunch box, and the lunch box falls downward under the action of gravity.

[0041] The first dropping mechanism 3 includes a cylinder and a first dropping plate 301; the cylinder is fixedly installed inside the frame 1, and the first dropping plate 301 is installed on the output end of the cylinder and is snapped onto the edge of the lunch box through its upper side.

[0042] The upper side of the first dropping plate 301 is provided with a second arc-shaped curved edge 3011, which is used to snap onto the edge of the lunch box to support the lunch box.

[0043] When the cylinder extends, the second arc-shaped curved edge 3011 on the lower side of the first dropping plate 301 engages with the edge of the lunch box to lift the lunch box.

[0044] When the cylinder resets, the second arc-shaped curved edge 3011 of the first falling plate 301 retracts and moves away from the edge of the lunch box, thus canceling the support for the lunch box, and the lunch box falls downward under the action of gravity.

[0045] The first lifting plate 201 and the first lowering plate 301 driven by the cylinder, together with the arc-shaped curved edge design, can not only stably support the edge of the lunch box, but also achieve smooth release, avoiding jamming or damage to the lunch box.

[0046] The lifting mechanism 2 and the first falling mechanism 3 are used to control the lifting state of two adjacent lunch boxes. With this configuration, combined with the staggered activation of the lifting mechanism 2 and the first falling mechanism 3, the single lunch box can be lowered.

[0047] Furthermore, in order to balance the force on the lunch boxes, a second dropping mechanism 4 is also included. The second dropping mechanism 4 is disposed on the front and rear sides of the receiving cavity and is used to control the lifting state of the lower lunch box in the stacked lunch boxes.

[0048] Combined with the second dropping mechanism 4 on the front and rear sides, it further improves the adaptability to different sizes of lunch boxes. The overall structure is simple and reliable, effectively solving the problems of double dropping or jamming that are easy to occur in traditional box dropping devices.

[0049] The combination design of the second falling mechanism 4 and the first falling mechanism 3 ensures that the lunch box falls in a balanced manner through four-way coordinated lifting, which is especially suitable for larger (or heavier) lunch boxes.

[0050] The second falling mechanism 4 and the first falling mechanism 3 are at the same horizontal height, so that the second falling mechanism 4 and the first falling mechanism 3 simultaneously lift the edges of a lunchbox.

[0051] The second dropping mechanism 4 includes a cylinder and a second dropping plate 401; the cylinder is fixedly installed inside the frame 1, and the second dropping plate 401 is installed on the output end of the cylinder and is engaged with the edge of the lunch box by its upper side.

[0052] The upper side of the second lower plate 401 is provided with a third arc-shaped curved edge 4011, which is used to engage with the edge of the lunch box to support the lunch box.

[0053] When the cylinder extends, the third arc-shaped curved edge 4011 on the lower side of the second lower plate 401 engages with the edge of the lunch box, thereby lifting the lunch box.

[0054] When the cylinder resets, the third arc-shaped curved edge 4011 of the second lower plate 401 retracts and moves away from the edge of the lunch box, thus canceling the support for the lunch box, and the lunch box falls downward under the action of gravity.

[0055] Of course, in order to ensure the precise descent of a single lunchbox, the first descent mechanism 3 and the second descent mechanism 4 are controlled synchronously.

[0056] The working process of the box-dropping mechanism of this utility model is as follows:

[0057] 1. In the initial state, the cylinders of the lifting mechanism 2, the first lowering mechanism 3, and the second lowering mechanism 4 are all in the extended state:

[0058] The first lifting plate 201 of the lifting mechanism 2 is engaged with the lower edge of the upper food container via the first arc-shaped curved edge 2011, supporting all the upper food containers.

[0059] The first dropping plate 301 of the first dropping mechanism 3 and the second dropping plate 401 of the second dropping mechanism 4 are engaged around the perimeter below the edge of the bottommost food container via the second curved edge 3011 and the third curved edge 4011.

[0060] 2. When it is necessary to release a single lunchbox:

[0061] a) The cylinder of the first falling mechanism 3 is reset first, which drives the first falling plate 301 to retract, so that the second arc-shaped curved edge 3011 is separated from the edge of the bottom food box; the second falling mechanism 4 on the front and rear sides moves synchronously with the first falling mechanism 3.

[0062] b) The bottom food container falls freely under the influence of gravity. At this time, the lifting mechanism 2 remains in a lifting state to ensure that the upper food container will not fall with it.

[0063] 3. After completing a single box drop:

[0064] a) The cylinder of the first dropping mechanism 3 extends again, causing the first dropping plate 301 to move to below the edge of the second to last layer of lunch box (the bottom layer of the original upper lunch box); the second dropping mechanisms 4 on the front and rear sides move synchronously with the first dropping mechanism 3.

[0065] b) The cylinder of the lifting mechanism 2 briefly resets and then immediately extends again, adjusting the position of the first lifting plate 201 to below the edge of the new upper food container.

[0066] 4. Repeat the above process to achieve continuous and stable single-box dropping, releasing only the bottommost box in the stack of boxes each time.

[0067] By controlling the cylinder's precise timing and using a smooth contact design with an arc-shaped curved edge, problems such as double-dropping and jamming are effectively avoided.

[0068] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
