Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, and in particular to a tray pressing and separating device. Background Technology

[0002] In industrial production processes such as food processing, pallets are often used to support products to be processed. In practice, products are usually placed on pallets and transported along with the pallets to freezing equipment for low-temperature treatment. After freezing, due to the rapid drop in temperature, the products often stick to the surface of the pallet, forming a physical adhesion.

[0003] After freezing, the product needs to be separated from the pallet for subsequent processing. The pallet can also be returned to the front-end station for reuse, thereby reducing usage costs and improving production efficiency.

[0004] In existing technologies, the separation process of products from pallets mostly relies on manual operation, that is, the operator manually separates the product from the pallet.

[0005] This method is not only labor-intensive, but its production cycle is also limited by the speed of manual operation, making it difficult to meet the demands of modern food processing enterprises for high-efficiency, automated, and continuous production. Furthermore, manual separation carries the risk of inconsistent operation, damage to products or trays, and difficulty in ensuring product quality stability. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a tray pressing and separating device to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0007] The solution to the technical problem of this utility model is: A pallet pressing and separating device is provided with mutually orthogonal pallet conveying direction, width direction, and unloading direction; the pallet pressing and separating device includes: A pallet conveyor line for conveying pallets along the pallet conveying direction; the pallet conveyor line is provided with a product discharge port; A pressing and separating mechanism is located above the product discharge port; the pressing and separating mechanism includes: The pressing mechanism is used to press the tray to separate the tray from the products it carries; A pressing drive structure drives the pressing structure to reciprocate towards and away from the tray conveyor line; When the pallet carrying the product passes under the pressing and separating mechanism, the pressing structure presses the pallet, causing the pallet to separate from the product. The product leaves the pallet conveyor line through the product discharge port due to gravity.

[0008] As a further improvement to the above technical solution, the pallet conveyor line includes a first conveying section, the beginning of which coincides with the beginning of the pallet conveyor line and the end of which coincides with the end of the pallet conveyor line; the first conveying section includes two first conveyor belt structures, which are arranged at intervals along the width direction, and a hollow space is formed between the two first conveyor belt structures.

[0009] As a further improvement to the above technical solution, the pallet conveyor line further includes a second conveyor section, the beginning of which coincides with the beginning of the pallet conveyor line and the end of which is located upstream of the product discharge port; the second conveyor section includes multiple second conveyor belt structures, which are arranged within the hollow space.

[0010] As a further improvement to the above technical solution, the pallet conveyor line further includes: two conveyor guide limiting rods, which are arranged opposite to each other on both sides of the pallet conveyor line. The conveyor guide limiting rods extend along the pallet conveying direction and are used to limit and guide the pallet.

[0011] As a further improvement to the above technical solution, the conveying guide limiting rod is provided with a guide section, which is located at the beginning of the pallet conveying line; along the pallet conveying direction, the guide section gradually approaches the inner side of the pallet conveying line along the width direction.

[0012] As a further improvement to the above technical solution, a receiving structure is provided below the product discharge port. The receiving structure is used to receive the product and guide it to downstream equipment.

[0013] As a further improvement to the above technical solution, the receiving structure includes: The receiving slide plate has a high receiving end and a low receiving end; the high receiving end is connected to the product drop port, and the low receiving end is lower than the high receiving end, so that the product can slide down along the receiving slide plate; There are two receiving side guards, which are respectively set on both sides of the receiving slide plate. The receiving side guards are used to limit the product to prevent the product from falling off one side of the receiving slide plate.

[0014] As a further improvement to the above technical solution, the pressing separation mechanism further includes: The pressing drive structure is connected to the pressing turntable via a transmission structure, and the pressing drive structure drives the pressing turntable to rotate. The pressing structure is provided in multiple ways, and the multiple pressing structures are arranged in a ring around the pressing turntable.

[0015] As a further improvement to the above technical solution, the rotation axis of the pressing turntable is parallel to the width direction.

[0016] As a further improvement to the above technical solution, the outer peripheral surface of the pressing structure includes a main pressing surface, which is a cylindrical surface.

[0017] The beneficial effects of this invention are as follows: when a pallet carrying products passes under the pressing and separating mechanism, the pressing structure presses down on the pallet, separating the pallet from the products. Due to gravity, the products fall from the product discharge port along the feeding direction and detach from the pallet conveyor line. This pallet pressing and separating device can achieve automated separation of the pallet and products, reducing manual intervention and improving production efficiency.

[0025] In industrial production processes such as food processing, pallets are often used to support products to be processed. In practice, products are usually placed on pallets and transported along with the pallets to freezing equipment for low-temperature treatment. After freezing, due to the rapid drop in temperature, the products often stick to the surface of the pallet, forming a physical adhesion.

[0026] After freezing, the product needs to be separated from the pallet for subsequent processing. The pallet can also be returned to the front-end station for reuse, thereby reducing usage costs and improving production efficiency.

[0027] In existing technologies, the separation process of products from pallets mostly relies on manual operation, that is, the operator manually separates the product from the pallet.

[0028] This method is not only labor-intensive, but its production cycle is also limited by the speed of manual operation, making it difficult to meet the demands of modern food processing enterprises for high-efficiency, automated, and continuous production. Furthermore, manual separation carries the risk of inconsistent operation, damage to products or trays, and difficulty in ensuring product quality stability.

[0029] This solution was designed to address the aforementioned technical problems, such as low product processing efficiency.

[0030] Reference Figure 1 and Figure 2 The pallet pressing and separating device has a pallet conveying direction, a width direction, and a discharging direction. The pallet conveying direction, width direction, and discharging direction are orthogonal to each other. Referring to the diagram, the pallet conveying direction is parallel to the X-axis, the width direction is parallel to the Y-axis, and the discharging direction is parallel to the Z-axis.

[0031] The pallet pressing and separating device mainly includes a frame 100, a pallet conveyor line 200, a pressing and separating mechanism 300, and a receiving structure 400. The pallet conveyor line 200, the pressing and separating mechanism 300, and the receiving structure 400 are all fixedly installed on the frame 100.

[0032] Pallet conveyor 200 is used to transport pallets carrying products along the pallet conveying direction (on pallet conveyor 200, the pallet opening is set downward so that the product can be detached from the pallet after subsequent pressing). The beginning of pallet conveyor 200 is used to connect with upstream equipment, and the end is used to connect with downstream pallet handling equipment.

[0033] The pallet conveyor line 200 is equipped with a product discharge port (the product discharge port is not shown in the figure).

[0034] The pallet conveyor line 200 includes: a first conveyor section 210, a second conveyor section 220, and a conveyor guide limit rod 230.

[0035] The beginning of the first conveyor line coincides with the beginning of the pallet conveyor line 200, and the end of the first conveyor line coincides with the end of the pallet conveyor line 200. Specifically, the first conveyor line includes two first conveyor belt structures, which are arranged along the width direction, and a hollow space is formed between the two first conveyor belt structures.

[0036] Specifically, the first conveyor belt structure is a conventional synchronous belt conveyor structure, which includes a drive motor, synchronous pulleys, synchronous belts, etc. Those skilled in the art are familiar with the specific construction of the first conveyor belt structure, and will not be described in detail here. To ensure that the conveying speed of the two first conveyor belt structures is consistent, the two first conveyor belt structures share the same drive motor and use the same transmission structure to avoid different speeds on both sides of the pallet, thereby preventing adverse situations such as pallet rotation or displacement during the conveying process of the first conveyor line.

[0037] The beginning of the second conveyor section 220 coincides with the beginning of the pallet conveyor line 200, and the end of the second conveyor section 220 is located downstream of the product discharge port. Specifically, the second conveyor line includes two second conveyor belt structures arranged along the width direction. In other embodiments, the number of second conveyor belt structures can also be set to three, four, or other quantities. Those skilled in the art can select the specific number of second conveyor belt structures according to actual needs. Both second conveyor belt structures are disposed within the hollow space.

[0038] Specifically, the second conveyor belt structure is configured as a conventional synchronous belt conveyor structure. The second conveyor belt structure shares the same drive motor and uses the same transmission structure as the first conveyor belt structure to ensure that the conveying speeds of the first and second conveyor belt structures are the same.

[0039] Two conveyor guide limit rods 230 are provided, arranged along the width direction and positioned opposite each other on both sides of the pallet conveyor line 200. By providing conveyor guide limit rods 230 on both sides of the pallet conveyor line 200, the pallet can be limited and guided, allowing the pallet to move along a designated trajectory and preventing the pallet from accidentally detaching from the pallet conveyor line 200, thereby ensuring the normal operation of this pallet pressing and separating device.

[0040] Specifically, in this embodiment, the conveying guide limiting rod 230 is provided with a guide section 231. The guide section 231 is located at the beginning of the pallet conveying line 200. The guide section 231 is an inclined rod-shaped member. The guide section 231 gradually approaches the inner side of the pallet conveying line 200 along the pallet conveying direction. By providing the guide section 231, the pallet entering the pallet pressing and separating device from upstream can be guided, so that the pallet can smoothly enter the pallet pressing and separating device.

[0041] The pressing and separating mechanism 300 is disposed above the product discharge port. Specifically, in this embodiment, the pressing and separating mechanism 300 includes: a pressing drive structure 310, a pressing turntable 320, and a pressing structure 330.

[0042] The pressing drive structure 310 is fixedly installed on the frame 100, and the pressing drive structure 310 is a rotary motor.

[0043] The pressing turntable 320 is rotatably mounted on the frame 100. The pressing turntable 320 is connected to the output end of the pressing drive structure 310 via a transmission structure. The pressing drive structure 310 drives the pressing turntable 320 to rotate around an axis parallel to its width. Specifically, the transmission structure between the pressing turntable 320 and the pressing drive structure 310 is not shown in the figure. In this embodiment, the transmission structure is a combination of a transmission belt and a transmission pulley. In other embodiments, the transmission structure can also be a combination of multiple transmission gears. Those skilled in the art can select the specific construction of the transmission structure between the pressing turntable 320 and the pressing drive structure 310 according to actual needs.

[0044] The number of pressing structures 330 is set to multiple, and the multiple pressing structures 330 are arranged in a ring on the pressing turntable 320, and the multiple pressing structures 330 are equally spaced on the pressing turntable 320.

[0045] The outer peripheral surface of the pressing structure 330 includes a main pressing surface 331 and a connecting pressing surface 332. The number of connecting pressing surfaces 332 is set to two, and the two connecting pressing surfaces 332 are respectively disposed on both sides of the main pressing surface 331 in the width direction.

[0046] The main pressing surface 331 is cylindrical, and the connecting pressing surface 332 is frustum-shaped. The main pressing surface 331 is used to press the pallet, separating it from the product it carries. The frustum-shaped connecting pressing surface 332 helps to mitigate the instantaneous deformation of the main pressing surface 331 upon contact with the pallet, preventing excessive deformation or even damage to the pallet caused by abrupt changes in diameter at the edge of the main pressing surface 331. This transitional structure of the connecting pressing surface 332 allows for smoother and more continuous deformation of the pallet during pressing, thereby improving structural adaptability and reliability.

[0047] During operation, the pressing turntable 320 rotates synchronously with the operation of the pallet conveyor line 200, so that multiple pressing structures 330 can maintain relative synchronous movement with the pallet passing below them, realizing continuous pressing operation without interrupting the conveying process, thereby avoiding the pallet conveyor line 200 from stopping and improving the overall line operating efficiency.

[0048] The cylindrical and frustum-shaped structures of the main pressing surface 331 and the connecting pressing surface 332 ensure that the pressing structure 330 remains in contact with the corresponding tray surface during the rotation of the turntable, and applies pressing force in a gradually deepening manner, avoiding sudden pressure that could damage the tray structure.

[0049] In other embodiments, the pressing drive structure 310 can be set as a conventional linear drive device such as a linear motor or linear cylinder, and the pressing turntable 320 can be omitted. The pressing drive structure 310 directly drives the pressing structure 330 to move back and forth along the unloading direction towards the pallet conveyor line 200, thereby pressing the pallet to separate the pallet and the products it carries. Those skilled in the art can select the specific structure of the pressing separation mechanism 300 according to actual needs, so that the pressing structure 330 of the pressing separation mechanism 300 can continuously move back and forth towards the pallet conveyor line 200, so that the pressing structure 330 can press the pallet.

[0050] The receiving structure 400 is located below the product discharge port. The receiving structure 400 is used to prevent the product from scattering and to achieve automatic flow guidance.

[0051] Specifically, the receiving structure 400 includes: a receiving slide plate and a receiving side guard.

[0052] The receiving slide plate has a high receiving end and a low receiving end. The high receiving end connects to the product drop port, and the low receiving end is lower than the high receiving end. After the product falls from the product drop port onto the receiving structure 400, the product can slide downwards along the receiving slide plate because the receiving slide plate has a height difference.

[0053] Two receiving side stops are provided, one on each side of the receiving slide plate. These side stops limit the movement of the product, preventing it from shifting or falling off one side of the receiving slide plate, thus ensuring the product smoothly enters the downstream equipment.

[0054] The implementation process of this solution is as follows: when the pallet carrying the product passes under the pressing and separating mechanism 300, the pressing structure 330 presses the pallet, causing the pallet to separate from the product. Due to gravity, the product falls from the product discharge port along the discharge direction and leaves the pallet conveyor line 200.

[0055] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
