Abstract
Description
Technical Field
[0001] This utility model belongs to the field of food processing machinery manufacturing, and in particular relates to a positioning mechanism for opening and closing food processing. Background Technology
[0002] Lollipops are a type of candy loved by many people. They come in various names, including windmill lollipops. They are typically made by inserting a candy stick onto a stick. Many more delicious and fun varieties have been developed, making them popular with consumers. Types of lollipops include gel candy, hard candy, milk candy, chocolate candy, milk and fruit candy, and more. During lollipop manufacturing, after inserting the stick into the candy, packaging is often required. This involves wrapping the candy with candy wrapper. A clamping mechanism holds the stick in place, and an external twisting device rotates and tightens the wrapper, thus forming the package. The clamping mechanism often operates in two modes: clamping and opening. After clamping the stick, the twisting device tightens the wrapper, and then the clamping mechanism opens to separate the stick for subsequent processing. Therefore, a convenient and flexible structure needs to be designed for processing, requiring structural research and development. Utility Model Content
[0003] To address the shortcomings of the existing technology, this utility model provides a convenient, stable, and reliable opening and closing positioning mechanism for food processing.
[0004] To solve the above problems, the technical solution adopted by this utility model is as follows:
[0005] A closing positioning mechanism for food processing includes a rotating disk, a positioning disk, and closing clamping units. The positioning disk is mounted on the inner side of the rotating disk. The rotating disk rotates on the outer side of the positioning disk. The positioning disk has a convex arc section and a concave arc section on its four sides. Multiple closing clamping units are evenly mounted around the rotating disk. Each closing clamping unit includes a driving rotating rod, a driven rotating rod, a driving clamping rod, a driven clamping rod, and a contacting protrusion. The driving and driven rotating rods are rotatably mounted on the rotating disk. A driving clamping rod is mounted on the outer end of the driving rotating rod. A driven clamping rod is mounted on the outer end of the driven rotating rod. The driving and driven clamping rods form a cross clamping mechanism. Structure: An abutting protrusion is installed on the inner side of the active rotating rod; the outer end of the abutting protrusion abuts against the surrounding surface of the positioning disk; the rotating disk rotates and drives multiple opening and closing clamping units to rotate synchronously. When the outer end of the abutting protrusion abuts against the convex arc surface section of the positioning disk, the abutting protrusion is pressed by the convex arc surface section and rotates outward. The rotation of the abutting protrusion drives the active rotating rod and the driven rotating rod to rotate relative to each other, causing the active clamping rod and the driven clamping rod to open. When the outer end of the abutting protrusion abuts against the concave arc surface section of the positioning disk, the abutting protrusion rotates inward. The rotation of the abutting protrusion drives the active rotating rod and the driven rotating rod to rotate relative to each other, causing the active clamping rod and the driven clamping rod to clamp.
[0006] Furthermore, the active rotating rod is provided with an active engagement block; the driven rotating rod is provided with a driven engagement block; the inner sides of the active engagement block and the driven engagement block are connected by meshing teeth.
[0007] Furthermore, a first torsion spring and a second torsion spring are respectively sleeved on the active rotating rod and the driven rotating rod; the inner ends of the first torsion spring and the second torsion spring are fixed to the active rotating rod and the driven rotating rod, respectively; the lower sides of the outer ends of the first torsion spring and the second torsion spring are elastically connected by elastic connecting ribs.
[0008] Furthermore, the active clamping rod is provided with a through slot; the driven clamping rod passes through the through slot of the active clamping rod and forms an X-shaped structure.
[0009] Furthermore, the inner side of the active clamping rod has an arc-shaped structure; the end of the driven clamping rod is provided with an arc-shaped abutment block, and the inner side of the arc-shaped abutment block is provided with a clamping rod opening; when the active clamping rod and the driven clamping rod are clamped, the arc-shaped abutment block abuts against the inner side of the active clamping rod.
[0010] Furthermore, the outer end of the abutting protrusion is provided with a rolling wheel; the rolling wheel is in rolling connection with the surrounding surface of the positioning disk.
[0011] Furthermore, the surrounding surface of the positioning disk is made of a wear-resistant material.
[0012] Furthermore, the convex arc section and the concave arc section on the positioning disk are connected by a smooth arc transition.
[0013] The beneficial effects of this utility model are as follows:
[0014] 1. This utility model can form a stable clamping and opening operation. The rotating disk of this utility model rotates and drives multiple opening and closing clamping units to rotate synchronously. The abutting protrusion will successively abut against the outer convex arc section and the inner concave arc section on the periphery of the positioning disk. When the abutting protrusion abuts against the outer convex arc section of the positioning disk, the abutting protrusion is pressed by the outer convex arc section and rotates outward. The rotation of the abutting protrusion drives the active rotating rod and the driven rotating rod to rotate relative to each other, and causes the active clamping rod and the driven clamping rod to open. When the abutting protrusion abuts against the inner concave arc section of the positioning disk, the abutting protrusion rotates inward. The rotation of the abutting protrusion drives the active rotating rod and the driven rotating rod to rotate relative to each other, and causes the active clamping rod and the driven clamping rod to clamp. In this way, stable operation can be achieved.
[0015] 2. This utility model features an active engagement block on the active rotating rod and a driven engagement block on the driven rotating rod. The inner sides of the active and driven engagement blocks are connected by teeth for meshing and rotation. This allows the active and driven rotating rods to mesh and rotate relative to each other. When the outer end of the abutting protrusion abuts against the convex arc section of the positioning plate, the abutting protrusion is pressed by the convex arc section and rotates outward. The abutting protrusion drives the active rotating rod to rotate, and the rotation of the active rotating rod, in turn, drives the driven rotating rod to rotate through meshing transmission. The rotating rods rotate relative to each other, causing the active and driven clamping rods to open and close. When the abutting protrusion abuts against the concave arc section of the positioning plate, the abutting protrusion is no longer pressed by the convex arc section. The active and driven rotating rods can obtain a stable elastic restoring force for mutual rotation and reset through the first torsion spring, the second torsion spring, and the elastic connecting rib. This makes the clamping movement of the active and driven clamping rods more stable, which facilitates the opening and closing movement of the active and driven clamping rods, achieving stable clamping and opening.
[0016] 3. This utility model features a convex arc section and a concave arc section on the four sides of the positioning plate. This design allows the active and passive clamping rods to remain open for a period of time and closed for a period of time. This ensures stable and sufficient material discharge when open and stable packaging when closed, resulting in a reliable structure.
[0017] 4. The active clamping rod of this utility model is provided with a through slot, and the driven clamping rod passes through the through slot of the active clamping rod to form an X-shaped structure. Through the X-shaped cross clamping structure and the relative rotation of the driven rotating rod and the active rotating rod, the driven clamping rod and the active clamping rod are less likely to collide with the driven clamping rods and the active clamping rod of other opening and closing clamping units when they are opened. The structure is stable and the driving process is simple and reliable. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.
[0023] like Figures 1 to 4As shown, a closing positioning mechanism for food processing includes a rotating disk 1, a positioning disk 2, and closing clamping units 3. The positioning disk 2 is installed on the inner side of the rotating disk 1. The rotating disk 1 rotates on the outer side of the positioning disk 2. The positioning disk 2 has a convex arc section 21 and a concave arc section 22 on its four sides. Multiple closing clamping units 3 are evenly installed around the rotating disk 1. Each closing clamping unit 3 includes an active rotating rod 31, a driven rotating rod 32, an active clamping rod 33, a driven clamping rod 34, and an abutting protrusion 35. The active rotating rod 31 and the driven rotating rod 32 are rotatably mounted on the rotating disk 1. The active clamping rod 33 is installed on the outer end of the active rotating rod 31. The driven clamping rod 34 is installed on the outer end of the driven rotating rod 32. The active clamping rod 33 and the driven clamping rod 34 form a cross clamping mechanism. Structure: The inner end of the active rotating rod 31 is fitted with an abutting protrusion 35; the outer end of the abutting protrusion 35 abuts against the surrounding surface of the positioning disk 2; the rotating disk 1 rotates and drives multiple opening and closing clamping units 3 to rotate synchronously. When the outer end of the abutting protrusion 35 abuts against the convex arc section 21 of the positioning disk 2, the abutting protrusion 35 is pressed by the convex arc section 21 and rotates outward. The rotation of the abutting protrusion 35 drives the active rotating rod 31 and the driven rotating rod 32 to rotate relative to each other, causing the active clamping rod 33 and the driven clamping rod 34 to open. When the outer end of the abutting protrusion 35 abuts against the concave arc section 22 of the positioning disk 2, the abutting protrusion 35 rotates inward. The rotation of the abutting protrusion 35 drives the active rotating rod 31 and the driven rotating rod 32 to rotate relative to each other, causing the active clamping rod 33 and the driven clamping rod 34 to clamp.
[0024] like Figures 1 to 4 As shown, in order to facilitate the relatively stable rotation of the active rotating rod 31 and the driven rotating rod 32, the active rotating rod 31 is further provided with an active engagement block 311; the driven rotating rod 32 is provided with a driven engagement block 321; the inner sides of the active engagement block 311 and the driven engagement block 321 are connected by meshing teeth.
[0025] like Figures 1 to 4 As shown, in order for the active rotating rod 31 and the driven rotating rod 32 to obtain a stable elastic restoring force for relative rotation, a first torsion spring 4 and a second torsion spring 5 are respectively sleeved on the active rotating rod 31 and the driven rotating rod 32; the inner ends of the first torsion spring 4 and the second torsion spring 5 are fixed to the active rotating rod 31 and the driven rotating rod 32 respectively; the lower sides of the outer ends of the first torsion spring 4 and the second torsion spring 5 are elastically connected by an elastic connecting rib 6.
[0026] like Figures 1 to 4As shown, in order to achieve stable rotation and avoid collisions, the active clamping rod 33 is further provided with a through slot 331; the driven clamping rod 34 passes through the through slot 331 of the active clamping rod 33 and forms an X-shaped structure.
[0027] like Figures 1 to 4 As shown, to facilitate the stabilization of the clamping rod, the inner surface of the active clamping rod 33 is further arc-shaped; the end of the driven clamping rod 34 is provided with an arc-shaped abutment block 341, and the inner side of the arc-shaped abutment block 341 is provided with a clamping rod opening 342; when the active clamping rod 33 and the driven clamping rod 34 are clamped, the arc-shaped abutment block 341 abuts against the inner surface of the active clamping rod 33. Furthermore, the outer end of the abutment protrusion 35 is provided with a rolling wheel 351; the rolling wheel 351 is in rolling connection with the surrounding surface of the positioning disk 2. Furthermore, the surrounding surface of the positioning disk 2 is made of wear-resistant material. Furthermore, the convex arc-shaped section 21 and the concave arc-shaped section 22 on the positioning disk 2 are connected by a smooth arc transition.
[0028] This invention enables stable clamping and opening operations. The rotating disk 1 rotates, driving multiple opening and closing clamping units 3 to rotate synchronously. The abutting protrusion 35 sequentially abuts against the convex arc section 21 and the concave arc section 22 on the surrounding surface of the positioning disk 2. When the abutting protrusion 35 abuts against the convex arc section 21 of the positioning disk 2, the abutting protrusion 35 is pressed by the convex arc section 21 and rotates outward. The rotation causes the active rotating rod 31 and the driven rotating rod 32 to rotate relative to each other, and causes the active clamping rod 33 and the driven clamping rod 34 to open. When the abutting protrusion 35 abuts against the concave arc section 22 of the positioning plate 2, the abutting protrusion 35 rotates inward. The rotation of the abutting protrusion 35 causes the active rotating rod 31 and the driven rotating rod 32 to rotate relative to each other, and causes the active clamping rod 33 and the driven clamping rod 34 to clamp together, thus enabling stable operation.
[0029] This invention features an active engagement block 311 on the active rotating rod 31 and a driven engagement block 321 on the driven rotating rod 32. The inner sides of the active engagement block 311 and the driven engagement block 321 are connected by meshing teeth, allowing the active rotating rod 31 and the driven rotating rod 32 to mesh relative to each other and rotate. When the outer end of the abutting protrusion 35 abuts against the convex arc section 21 of the positioning disk 2, the abutting protrusion 35 is pressed by the convex arc section 21 and rotates outward. The abutting protrusion 35 drives the active rotating rod 31 to rotate, and the rotation of the active rotating rod 31 drives the active rotating rod 31 to rotate through meshing transmission. The driven rotating rod 32 rotates relative to each other, thus causing the active clamping rod 33 and the driven clamping rod 34 to open. When the abutting protrusion 35 abuts against the concave arc section 22 of the positioning plate 2, the abutting protrusion 35 is no longer pressed by the convex arc section 21. The active rotating rod 31 and the driven rotating rod 32 can obtain a stable elastic restoring force for mutual rotational reset through the first torsion spring 4, the second torsion spring 5, and the elastic connecting rib 6, so that the active clamping rod 33 and the driven clamping rod 34 can clamp more stably. This facilitates the opening and closing movement of the active clamping rod 33 and the driven clamping rod 34, achieving stable clamping and opening.
[0030] This utility model designs a convex arc section 21 and a concave arc section 22 on the four sides of the positioning disk 2, so that the active clamping rod 33 and the driven clamping rod 34 are open for a period of time and closed for a period of time. This allows for stable and sufficient material discharge when open and stable packaging when closed, resulting in a reliable structure.
[0031] The active clamping rod 33 of this utility model is provided with a through slot 331. The driven clamping rod 34 passes through the through slot 331 of the active clamping rod 33 and forms an X-shaped structure. Through the X-shaped cross clamping structure and the relative rotation of the driven rotating rod 32 and the active rotating rod 31, the driven clamping rod 34 and the active clamping rod 33 are less likely to collide with the driven clamping rods 34 and the active clamping rod 33 of other opening and closing clamping units 3 when they are opened. The structure is stable and the driving process is simple and reliable.
[0032] 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, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
