Abstract

The invention discloses a time-delay clamping mechanism for food packaging thread twisting. The time-delay clamping mechanism comprises a positioning frame, an opening and closing driving assembly, a rotating column, a clamping plate, a clamping rod and an abutting spring. A clamping rod is installed on the inner side of a clamping plate, a sliding clamping groove is formed in a rotating column, the inner end of the clamping rod is clamped to the sliding clamping groove in a sliding mode, an abutting spring is installed in the sliding clamping groove, and the abutting spring abuts against the clamping rod towards the inner side, so that the clamping plate can move on the rotating column in a telescopic mode through the clamping rod; therefore, when the clamping plate clamps the ribbon to start twisting and the external turntable drives the clamping plate to move to be separated from the ribbon, the clamping and twisting time of the clamping plate and the ribbon can be prolonged through compression of the pressing spring, too fast separation of the clamping plate and the ribbon is avoided, and the structural stability of wire twisting is guaranteed.

Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of food packaging thread, and particularly relates to a time-delay type food packaging thread clamping mechanism. BACKGROUND

[0002] In recent years, lollipop is a kind of candy food that is deeply loved by the public. Initially, a hard candy is inserted on a small stick, and then many better-tasting and more fun varieties are developed, which are deeply loved by consumers. The types of lollipops include gelatin candy, hard candy, milk candy, chocolate, etc. The existing market lollipops are packaged by using a packaging mechanism. Generally, the candy body is wrapped by a paper bag, and then needs to be tightened by a ribbon. Generally, the ribbon is rotated and fastened on the paper bag, so that the entire packaging structure is stable. The existing way generally twists the ribbon by using a thread clamping structure. A plurality of clamping mechanisms are installed on a rotating disc. The clamping mechanisms can be opened and closed for clamping. The clamping mechanism rotates after clamping the ribbon, so that the ribbon is twisted. However, the current structure has several disadvantages. After clamping and positioning the ribbon, the clamping mechanism needs to rotate with the rotating disc, so that the clamping mechanism does not have sufficient time to clamp the ribbon for rotating and twisting. The clamping mechanism and the ribbon are separated by sliding, so that the ribbon is not sufficiently twisted. Meanwhile, the opening and closing of some clamping mechanisms are often through a hinge structure, and the opening and closing amplitude is small. Before clamping, the ribbon is easily collided. Therefore, the structure needs to be upgraded and improved to prolong the clamping and twisting time, improve the structural stability of the twisting, and improve the opening and closing amplitude of the clamping.

[0021] As Figs. 1 to 5 ​As shown in the figure, a kind of clamping mechanism for food packaging thread with delay, including positioning frame 1, open-close driving assembly 2, rotating column 3, clamping plate 4, clamping rod 5, pressing spring 6;The outer end of the positioning frame 1 is rotatably installed with a rotating column 3 on both sides;The outer end of the rotating column 3 is installed with a clamping plate 4 on both sides;The inner side of the clamping plate 4 is installed with a clamping rod 5;Sliding clamping groove 31 is formed in the rotating column 3;The inner end of the clamping rod 5 is slidably clamped in the sliding clamping groove 31;The pressing spring 6 is installed in the sliding clamping groove 31;The clamping rod 5 is inwardly pressed by the pressing spring 6;The open-close driving assembly 2 is installed on the positioning frame 1;The open-close driving assembly 2 includes telescopic guide rod 21;The telescopic guide rod 21 is slidably clamped on the positioning frame 1, and the inner end of the telescopic guide rod 21 extends to the outside of the positioning frame 1;When the inner end of the telescopic guide rod 21 is extruded by external force, the telescopic guide rod 21 moves to the inner end of the positioning frame 1, and the two rotating columns 3 are separated by rotating to both sides;When the inner end of the telescopic guide rod 21 is not extruded by external force, the telescopic guide rod 21 moves to the outer end of the positioning frame 1, and the two rotating columns 3 are rotated to the middle and form clamping and pressing movement.

[0022] As Figs. 1 to 5 shown, in order to improve the moving stability of the clamping rod 5, further, the inner end of the clamping rod 5 is provided with a moving clamping block 51;The moving clamping block 51 is slidably clamped in the sliding clamping groove 31;The moving clamping block 51 is inwardly pressed by the pressing spring 6.

[0023] As Figs. 1 to 5 shown, in order to open and close the rotating column 3, realize large opening, further, the open-close driving assembly 2 further includes end protrusion 22, rotating shaft 23, moving seat 24, driving plate 25, rotating wheel 26;The outer end of the positioning frame 1 is installed with an end protrusion 22 on both sides, and the outer end of the positioning frame 1 is rotatably clamped with a rotating shaft 23 on both sides, the two ends of the rotating shaft 23 are rotatably connected to the end protrusion 22, the two ends of the rotating shaft 23 extend to the outside of the end protrusion 22, the two ends of the rotating shaft 23 are installed with a rotating wheel 26, and the rotating shaft 23 is installed with a rotating column 3 on the middle upper side;The upper end of the telescopic guide rod 21 is installed with a moving seat 24, and the moving seat 24 is installed with a driving plate 25 on both sides;The outer side of the driving plate 25 and the rotating wheel 26 abut, and the driving plate 25 moves and drives the rotating wheel 26 to rotate in opposite directions. Further, the end protrusion 22 is provided with a rotating clamping channel 221;The two ends of the rotating shaft 23 are rotatably clamped in the rotating clamping channel 221 of the end protrusion 22. In order to facilitate transmission, further, the outer side of the driving plate 25 and the side of the rotating wheel 26 are in gear tooth plate engagement structure.

[0024] As Figs. 1 to 5As shown, in order to facilitate the reset of the telescopic guide rod 21, the positioning frame 1 is further provided with movable slots 11 on both sides of the interior; spring pressing members 12 are provided in the movable slots 11; sliding blocks 211 are provided on both sides of the telescopic guide rod 21; the sliding blocks 211 are slidably engaged with the movable slots 11 and the outer side of the sliding blocks 211 is subjected to the elastic pressing force of the spring pressing members 12.

[0025] like Figs. 1 to 5 As shown, to facilitate the external cam pressing against the telescopic guide rod 21, the inner end of the telescopic guide rod 21 has an outwardly convex arc surface structure. For ease of assembly, the positioning frame 1 has a U-shaped structure. To facilitate the self-rotation drive of the positioning frame 1, a ring gear 7 is provided around the outer perimeter of the inner end of the positioning frame 1.

[0026] The present invention has a locking rod 5 installed on the inner side of the clamping plate 4 and a sliding groove 31 opened on the rotating column 3. The inner end of the locking rod 5 is slidably locked onto the sliding groove 31, and a pressure spring 6 is installed in the sliding groove 31. The pressure spring 6 presses the locking rod 5 inward, so that the clamping plate 4 can move telescopically on the rotating column 3 through the locking rod 5. Thus, when the clamping plate 4 clamps the ribbon and begins to twist, when the external turntable drives the clamping plate 4 to move and separate from the ribbon, the compression of the pressure spring 6 can prolong the clamping and twisting time between the clamping plate 4 and the ribbon, avoiding the clamping plate 4 and the ribbon from separating too quickly and ensuring the structural stability of the twisted ribbon.

[0027] The present invention uses the telescopic guide rod 21 to drive the movable seat 24 to move, and the movable seat 24 to drive the drive plate 25 to move. In this way, the drive plate 25 engages with the rotating wheel 26 to rotate in both directions, thus realizing the full rotation of the rotating shaft 23. This drives the rotating column 3 and the clamping plate 4 to fully open and sink, avoiding the collision between the clamping plate 4 and the ribbon before clamping.

[0028] The structure of this invention is generally uniformly installed on a turntable, on which multiple devices of this invention are evenly distributed. When the telescopic guide rod 21 rotates with the turntable, the inner end of the telescopic guide rod 21 is pressed by the external cam, and the telescopic guide rod 21 moves inward toward the inner end of the positioning frame 1, causing the two rotating columns 3 to rotate and separate to both sides, thus forming an opening motion. When the inner end of the telescopic guide rod 21 separates from the external cam and is not squeezed by external force, the telescopic guide rod 21 moves outward toward the inner end of the positioning frame 1, causing the two rotating columns 3 to rotate toward the middle and form a clamping and pressing motion. This allows for opening and closing motion to clamp the ribbon. Then, the ring gear on the outer periphery of the inner end of the positioning frame 1 contacts the external rack and rotates, thus forming a clamping, rotating, and twisting operation, which is flexible and convenient to use.

[0029] The above merely provides the preferred embodiment of the present application, and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
