Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, specifically a tuna spine positioning sawing mechanism. Background Technology

[0002] Tuna is a nutritious and delicious saltwater fish with wide applications in food processing. During tuna processing, its backbone needs to be sawn to facilitate subsequent cutting and packaging. An existing patent, CN222074345U, describes a bone-sawing machine for eel processing. It lays the headless eel flat on a conveyor belt, then operates a first rotating drive unit, which drives the conveyor belt via a transmission shaft. The eel on the conveyor belt passes under a first pressing component, a second pressing component, and a third pressing component in sequence. When the front end of the eel passes under the second pressing component... At the same time, the second pressing component can be operated to press the fish meat on both sides of the eel's spine, so that the front end of the eel forms an arc with the cooperation of the second pressing component and the conveyor belt, allowing the bone-cutting mechanism to better penetrate into the fish meat to cut the spine. Then, the first rotating drive and the bone-cutting mechanism are operated simultaneously, so that the bone-cutting mechanism cuts the eel's spine from front to back. At the same time, the first pressing mechanism and the third pressing mechanism can be adjusted to press the fish meat, so that the eel will not shift during the bone-cutting process.

[0003] Regarding the aforementioned technologies, the inventors believe that the following drawbacks exist: Currently, most tuna spine sawing is done manually, with operators holding sawing tools to cut the spine. This method is not only labor-intensive and inefficient, but also makes it difficult to guarantee sawing accuracy, easily leading to problems such as sawing deviation or slant, affecting the quality of the tuna product. Furthermore, manual sawing poses certain safety hazards and can easily cause injury to operators. Therefore, we propose a tuna spine positioning sawing mechanism to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a tuna spine positioning sawing mechanism, which solves the problem that most tuna spine sawing is done manually. Operators hold sawing tools to saw the tuna spine, which is not only labor-intensive and inefficient, but also makes it difficult to guarantee sawing accuracy, easily resulting in problems such as sawing deviation and slant, affecting the quality of tuna products. In addition, there are certain safety hazards in the manual sawing process, which can easily cause injury to operators.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a tuna spine positioning sawing mechanism, including a support mechanism, wherein a transverse groove is provided inside the support mechanism, and a servo push rod is fixedly connected inside the transverse groove, and there are two servo push rods in total. The two servo push rods are fixedly connected to the left and right sides inside the support mechanism, and the inner sides of the two servo push rods are fixedly connected to moving components. The outer sides of the moving components are fixedly connected to two slider assemblies, and the top surface of the moving components is fixedly connected to a side plate assembly.

[0006] Preferably, a clamping assembly is fixedly connected to the outer side of the side plate assembly, and two clamping arm assemblies are installed facing each other inside the clamping assembly. The clamping assembly is a pneumatic clamping structure.

[0007] Preferably, the clamping assembly and the clamping arm assembly together form a positioning and clamping mechanism for the tuna spine, and a leg assembly is fixedly connected to the bottom end surface of the support mechanism, with two legs in total.

[0008] Preferably, the two support leg assemblies are fixedly connected to the left and right sides of the bottom end face of the support mechanism, and a bracket assembly is fixedly connected to the top surface of the support mechanism.

[0012] This invention provides a tuna spine positioning sawing mechanism. Compared with the prior art, it has the following advantages: This tuna spine positioning and sawing mechanism achieves automated positioning and clamping of the tuna spine through the cooperation of servo push rods, moving components, clamping components, and clamping arm components. It eliminates the need for manual hand-held fixation, reducing the labor intensity of operators. At the same time, it avoids the problem of loosening that may occur when manually fixing, which may lead to sawing deviation and improves sawing accuracy. In addition, the entire positioning and clamping process is completed by mechanical structure, reducing manual contact with the sawing tool and reducing safety hazards.

[0013] This tuna spine positioning sawing mechanism automates the sawing operation through the coordinated work of the support mechanism, sawing push rod, servo motor, and saw blade assembly. Compared with manual hand-held sawing tools, it not only improves work efficiency, but also ensures sawing accuracy by mechanically controlling the operation of the saw blade assembly and stabilizing the sawing path. This avoids problems such as sawing deviation and slant caused by unstable force and angle during manual operation, thereby improving the quality of tuna products. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-6 This utility model provides a technical solution: a tuna spine positioning sawing mechanism, including a support mechanism 1, the support mechanism 1 has a transverse groove inside, and a servo push rod 3 is fixedly connected inside the transverse groove. There are two servo push rods 3. Two servo push rods 3 are fixedly connected to the left and right sides inside the support mechanism 1, and a moving component 301 is fixedly connected to the inner side of each of the two servo push rods 3. Two slider components 3011 are fixedly connected to the outer side of the moving component 301, and a side plate component 3012 is fixedly connected to the top surface of the moving component 301. By setting two servo push rods 3 facing each other on the left and right sides inside the support mechanism 1, and connecting the inner side of the servo push rods 3 to the moving component 301, the moving component 301 has a slider component 3011 on the outside and a side plate component 3012 on the top, the stable lateral movement of the moving component 301 under the drive of the servo push rods 3 is realized, providing a basis for subsequent positioning and clamping.

[0018] See Figures 1-3 A clamping assembly 3013 is fixedly connected to the outside of the side plate assembly 3012. Two clamping arm assemblies 3014 are installed facing each other inside the clamping assembly 3013. The clamping assembly 3013 is a pneumatic clamping structure. By installing two opposing clamping arm assemblies 3014 inside the clamping assembly 3013 (pneumatic clamping structure) on the outside of the side plate assembly 3012, the clamping function of the tuna spine is realized, providing a clamping basis for positioning sawing.

[0019] See Figures 2-5 The clamping assembly 3013 and the clamping arm assembly 3014 together form a positioning clamping mechanism for the tuna spine. The support mechanism 1 has a leg assembly 101 fixedly connected to its bottom surface. The leg assembly 101 has two parts. The clamping assembly 3013 and the clamping arm assembly 3014 form a positioning clamping mechanism, which, together with the two support leg assemblies 101 at the bottom of the support mechanism 1, achieves stable positioning and clamping of the tuna spine, and the support leg assemblies 101 ensure the stable support of the entire mechanism.

[0020] See Figures 1-2 Two support leg assemblies 101 are fixedly connected to the left and right sides of the bottom end face of the support mechanism 1, and a bracket assembly 1011 is fixedly connected to the top surface of the support mechanism 1. The two support leg assemblies 101 on the left and right sides of the bottom end face of the support mechanism 1 and the bracket assembly 1011 at the top end achieve stable support for the support mechanism 1 and lift the tuna spine.

[0021] See Figures 3-6 The bracket assembly 1011 is used to support the tuna spine, and both the front and rear sides of the bracket assembly 1011 are inclined surfaces. A cutting groove 1012 is provided at the center of the top surface of the bracket assembly 1011. The inclined surface structure of the bracket assembly 1011 and the cutting groove 1012 at the center of the top surface enable the lifting and limiting guidance of the tuna spine, and provide space for sawing, ensuring smooth sawing.

[0022] See Figures 1-2 The support mechanism 1 is fixedly connected to the rear side of the bracket mechanism 2. There are two bracket mechanisms 2, and the two bracket mechanisms 2 are fixedly connected to the left and right sides of the rear end face of the support mechanism 1 in opposite directions. The two support mechanisms 2, which are set opposite each other on the left and right sides of the rear end face of the support mechanism 1, provide support for the subsequent sawing-related components and provide a structural foundation for the sawing operation.

[0023] See Figures 3-5 Support plate assemblies 201 are fixedly connected to the front end faces of the two support mechanisms 2. Longitudinal sawing push rods 2011 are fixedly connected to the bottom end faces of the two support plate assemblies 201. Base plate assembly 2012 is fixedly connected to the bottom end of the sawing push rod 2011. Servo motor 2013 is fixedly connected to the outside of the base plate assembly 2012. Saw blade assembly 2014 is installed on the output shaft of the servo motor 2013. The sawing components are installed and driven by the support plate assembly 201 at the front end of the support mechanism 2, the sawing push rod 2011 at the bottom end of the support plate assembly 201, the base plate assembly 2012 at the bottom end of the sawing push rod 2011, the servo motor 2013 on the outside of the base plate assembly 2012, and the saw blade assembly 2014 on the output shaft of the servo motor 2013, which can complete the automated sawing operation of tuna spine.

[0024] During operation, the tuna spine is first placed on the bracket assembly 1011 on the top surface of the support mechanism 1. The bracket assembly 1011 supports the tuna spine through its top surface, and the inclined surface structure on its front and rear sides can play a certain role in limiting and guiding the tuna spine. At the same time, the cutting groove 1012 in the center of the top surface of the bracket assembly 1011 reserves space for subsequent sawing operations. When the two servo push rods 3 inside the transverse groove of the support mechanism 1 are activated, since the two servo push rods 3 are fixed to the left and right sides inside the support mechanism 1, when the servo push rods 3 extend, they will push the moving component 301 fixedly connected to the inside to move inward. The two slider components 3011 on the outside of the moving component 301 slide in the transverse groove of the support mechanism 1, providing guidance and stability for the movement of the moving component 301. The movement of the movable component 301 causes the side plate component 3012, which is fixed at the top surface, to move synchronously. The clamping component 3013, which is fixed on the outside of the side plate component 3012, moves with the side plate component 3012 to the positions on both sides of the tuna spine. The clamping assembly 3013 is a pneumatic clamping structure. After it is started, the two opposing clamping arm assemblies 3014 inside it close inward to position and clamp the tuna spine, ensuring that it will not shift during the sawing process. The two support mechanisms 2 on the rear side of the support mechanism 1 provide support. The sawing push rod 2011 on the support plate assembly 201 fixed at the front end of the support mechanism 2 is activated. The sawing push rod 2011 extends longitudinally and pushes the bottom plate assembly 2012 fixed at the bottom end to move downward. The servo motor 2013, which is fixed on the outside of the base plate assembly 2012, moves down with the base plate assembly 2012. The servo motor 2013 starts, and its output shaft drives the saw blade assembly 2014 to rotate at high speed. The saw blade assembly 2014 moves down to the position of the cutting groove 1012 to perform sawing operations on the tuna spine that is positioned and clamped. After sawing is completed, servo motor 2013 stops working, saw blade assembly 2014 stops rotating, sawing push rod 2011 retracts, driving base plate assembly 2012, servo motor 2013 and saw blade assembly 2014 to move upward and reset; clamping assembly 3013 controls clamping arm assembly 3014 to open, releasing the sawn tuna spine; servo push rod 3 retracts, driving moving assembly 301, side plate assembly 3012, clamping assembly 3013 and clamping arm assembly 3014 to move outward and reset, completing one sawing process.

[0025] In summary, this device, equipped with a servo motor 2013, can achieve efficient cutting operations on the saw blade assembly 2014.

[0026] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
