[0031] See Figure 1-3 As shown, this embodiment provides a device for knotting strip-shaped food products, including:
[0032] frame;
[0033] Sliding components are vertically positioned at the top and bottom of the rack;
[0034] A support assembly is located on one side of the frame and is fixedly connected to the frame.
[0035] A shearing component is disposed on one side of the support component, and a fixed interval is provided between the shearing component and the support component;
[0036] The first moving component is positioned at the top of the sliding component;
[0037] The second moving component is located at the bottom of the sliding component, and the first moving component and the second moving component are positioned facing each other;
[0038] The knotting assembly is located on the other side of the rack.
[0039] In this embodiment, the process of the strip food 2 entering and being clamped and conveyed is as follows:
[0040] First, the No. 3 finger clamp cylinder 7 is in position ③, and the strip food 2 is clamped on the No. 3 finger clamp cylinder 7 by the support ring 1.
[0041] Then, the number three finger clamp cylinder 7 moves to the position as follows. Figure 1 At the indicated positions, clamping cylinders 5 (number one) and 6 (number two) begin operation, clamping the strip food 2. After clamping, clamping cylinder 7 (number three) opens, releasing the clamp and returning to position ③, continuing to clamp the strip food 2. At this time, shearing cylinder 3 operates, cutting the food. Subsequently, clamping cylinders 5 (number one) and 6 (number two) holding the strip food 2 move along slide rail 2 to positions ① and ②, thus completing the feeding cycle.
[0042] In this embodiment, the knotting process of the strip food 2 is as follows:
[0043] First, at the start of the knotting operation, the first finger-gripping cylinder 5 and the second finger-gripping cylinder 6 clamp the strip food 2 and move it to positions ① and ② via the second slide rail. At this time, the distance between the two cylinders changes from A to B, and A is greater than B. Under the action of gravity, the strip food 2 naturally bends and hangs downwards, as shown in the view from direction E. Figure 2 As shown in the figure.
[0044] After the food bends and droops, the semi-circular ring clamping cylinder 10 starts to work, clamping the strip-shaped food 2. Next, the rotating cylinder 9 rotates 180 degrees. While rotating, the first finger clamping cylinder 5 and the second finger clamping cylinder 6 continue to move closer, and the distance between them becomes C, where B is greater than C.
[0045] Finally, the knotting finger clamp cylinder 13 begins to operate, extending and passing through the center of the ring to clamp the strip of food 2 on one side of the first finger clamp cylinder 5. Then, as the knotting finger clamp cylinder 13 retracts, the first finger clamp cylinder 5 and the semi-circular ring clamping cylinder 10 simultaneously open, allowing the knotting and pulling work to be completed by the knotting finger clamp cylinder 13 and the second finger clamp cylinder 6. After knotting, the knotting finger clamp cylinder 13 opens first, followed by the second finger clamp cylinder 6, causing the knotted strip of food 2 to fall downwards into the collection device under the influence of gravity.
[0046] It is understandable that the strip food knotting device provided in this embodiment achieves fully automated knotting of the strip food 2, greatly improving production efficiency. This device, through the coordinated work of a sliding component, a support component, a shearing component, a first moving component, a second moving component, and a knotting component, completes the clamping, conveying, and knotting operations of the strip food 2. The design of the sliding component allows the strip food 2 to move smoothly in the vertical direction, while the support and shearing components ensure the stability and shearing accuracy of the strip food 2 during conveying. The opposing arrangement of the first and second moving components, and their cooperation with the sliding component, achieves precise clamping and conveying of the strip food 2. The ingenious design of the knotting component allows the strip food 2 to automatically complete the knotting operation without manual intervention.
[0047] Specifically, the sliding assembly includes guide rail 4 and guide rail 8;
[0048] Guide rail 4 is located at the top of the frame, and guide rail 8 is located at the bottom of the frame.
[0049] Understandably, the coordinated operation of guide rail 4 and guide rail 8 ensures the smooth vertical movement of the strip food 2. Guide rail 4 is responsible for the upward movement of the strip food 2, while guide rail 8 is responsible for its downward movement. This design not only improves the stability of the conveying of the strip food 2 but also effectively avoids possible jamming or deviation during the conveying process.
[0050] Specifically, the support assembly includes a support ring 1 and a support rod;
[0051] The support ring 1 is fixedly connected to one end of the support rod, and the other end of the support rod is fixedly connected to the frame.
[0052] Understandably, the design of the supporting ring 1 effectively supports the strip food 2 during transport, preventing inaccurate knotting or food damage caused by shaking during transport. Simultaneously, the fixed connection between the support rod and the frame ensures the stability and reliability of the support assembly, providing a strong guarantee for the smooth transport of the strip food 2.
[0053] Specifically, the shearing assembly includes a shearing cylinder 3 and a shearing blade;
[0054] The output shaft of the shearing cylinder 3 is fixedly connected to the shearing blade, and the shearing blade is driven to perform shearing operation by the extension and retraction of the shearing cylinder 3.
[0055] Understandably, the coordinated operation of the shearing cylinder 3 and the shearing blade ensures that the strip food 2 can be quickly and accurately cut after being conveyed to the designated position, providing strong support for subsequent knotting operations. The precise control of the shearing cylinder 3 makes the shearing operation both efficient and stable, avoiding food waste or reduced knotting quality caused by inaccurate shearing. At the same time, the sharpness and durability of the shearing blade have also been fully considered, ensuring long-term stability and reliability.
[0056] Specifically, the first moving component includes a first finger-clamping cylinder and a second finger-clamping cylinder 6. Both the first finger-clamping cylinder and the second finger-clamping cylinder 6 are located on the top of the second guide rail 8, and both are slidably connected to the second guide rail 8.
[0057] Understandably, the opposing arrangement of the first and second finger-grip cylinders 6, and their sliding connection with the second guide rail 8, enables precise clamping and stable conveying of the strip food 2. During conveying, the first and second finger-grip cylinders 6 can adjust the clamping force and position as needed, ensuring that the strip food 2 remains flat and does not easily slip before being conveyed to the knotting position. This not only improves the accuracy of conveying the strip food 2, but also effectively avoids potential food damage or inaccurate knotting during conveying. Simultaneously, the coordinated work of the first and second finger-grip cylinders 6 provides strong support for subsequent knotting operations, ensuring the smooth progress of the knotting process.
[0058] Specifically, the second moving component includes a third finger clamp cylinder 7, which is located at the bottom of the first guide rail 4, and the third bracket cylinder is slidably connected to the first guide rail 4.
[0059] Understandably, the placement of the No. 3 gripper cylinder 7 enables continuous clamping and conveying of the strip food 2 in the vertical direction. The sliding connection of the No. 3 gripper cylinder 7 to the bottom of the No. 1 guide rail 4 allows it to pre-clamp the strip food 2 before it is clamped by the No. 1 and No. 2 gripper cylinders 6, and then convey it to the designated position. This design not only improves the continuity of the conveying of the strip food 2 but also effectively avoids problems such as food falling or interruption of conveying during the process. Simultaneously, the sliding connection between the No. 3 gripper cylinder 7 and the No. 1 guide rail 4 ensures its stability and reliability during conveying, providing strong support for the smooth conveying of the strip food 2 and subsequent knotting operations.
[0060] Specifically, the output ends of the No. 1 finger-clamping cylinder, the No. 2 finger-clamping cylinder 6, and the No. 3 finger-clamping cylinder 7 are all equipped with clamps for clamping and moving the strip-shaped food 2.
[0061] Understandably, these clamps enable the cylinder to stably and securely hold the strip food 2, preventing it from slipping or deforming during conveying and knotting. The materials and shapes of the clamps have been carefully selected and optimized to ensure that the clamping force on the strip food 2 is moderate, neither damaging the food nor compromising its stability and accuracy during conveying and knotting. Furthermore, the adjustability of the clamps allows the device to adapt to strip food 2 of different sizes and shapes, improving its applicability and flexibility.
[0062] Specifically, the knotting assembly includes a rotary cylinder 9, a semi-circular ring clamping cylinder 10, a guide rail 11, a slider 12, and a knotting finger clamping cylinder 13; the guide rail 11 is arranged vertically and is fixedly connected to the frame; the slider 12 is arranged on the guide rail 11; the rotary cylinder 9 is arranged on the slider 12; the semi-circular ring clamping cylinder 10 is arranged on the rotary cylinder 9; and the knotting finger clamping cylinder 13 is arranged on the semi-circular ring clamping cylinder 10.
[0063] Understandably, the knotting assembly automates and efficiently knots the strip food 2. The rotation of the rotary cylinder 9 provides the necessary power for knotting the strip food 2, ensuring a smooth knotting process. The semi-circular ring clamping cylinder 10 is responsible for clamping the strip food 2 during the knotting process, preventing it from slipping or deforming. The guide rail 11 and slider 12 allow the rotary cylinder 9 and the semi-circular ring clamping cylinder 10 to move stably in the vertical direction, providing precise position control for the knotting operation. The telescopic movement of the knotting finger clamping cylinder 13 enables the clamping and knotting of the strip food 2, ensuring the stability and reliability of the knotting quality. The design of the entire knotting assembly fully considers the actual needs of the strip food 2 knotting operation. Through the coordinated work of various components, fully automated knotting of the strip food 2 is achieved, greatly improving production efficiency.
[0064] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
