Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of vacuum forming packaging, in particular to an arc-shaped follower structure of a drum-type packaging machine. Background Art
[0002] The vacuum forming process covers film insertion, vacuuming and adsorbing the film into the forming drum cavity, filling, sealing, slitting, and releasing the vacuum from the cavity. The forming cavity is customized according to the customer's shape requirements. Some beautiful shapes face many problems when using the old filling method because the discharge channel for the filling contents is too short. The traditional rotating drum with a fixed filling structure is only feasible for packaging types with square forming cavities and few peripheral curves, which greatly limits the customer's range of shape choices. Even if the shape is modified to adapt to filling, it will cause serious deformation and deviate from the expected effect. Another way to add a horizontal follower structure is to use a linear slider and a screw motor combination to enable the filling mechanism to move horizontally to extend the discharge channel and filling time. However, because the drum cavity moves in a circular motion and the horizontal follower structure only moves linearly, it is difficult to maintain accurate alignment and filling for shapes with complex shapes and short discharge channels, which can easily cause insufficient filling weight and affect product quality.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.
[0023] See also Figure 1-4 The utility model provides an arc-shaped follower structure of a forming drum packaging machine, comprising a filling valve mounting member 1 for mounting and fixing a filling valve, a suspension fixing member 2 for suspending the filling valve mounting member 1 above the forming drum, and an arc-shaped follower 3 for driving the filling valve mounting member 1 to perform an arc motion along the circumferential direction of the forming drum. The arc-shaped follower 3 is connected between the filling valve mounting member 1 and the suspension fixing member 2. The arc-shaped follower 3 comprises two vertical plates 31 arranged at both ends of the filling valve mounting member 1, an arc-shaped rack 32 movably mounted on the vertical plate 31, and a follower drive member meshing with the arc-shaped rack 32. The movable part is provided with an arc-shaped slide groove 311 with an internal thread on the vertical plate 31, and a roller 312 with an external thread is provided in the arc-shaped slide groove 311. A connecting rod 313 for connecting and fixing the arc-shaped rack 32 is provided on one side of the roller 312. A fixing plate 321 for connecting the filling valve mounting part 1 is provided on the side of the arc-shaped rack 32 away from the connecting rod 313. The follower driving part includes a driving motor 33 and a rotating shaft 34 connected to the output end of the driving motor 33. Both ends of the rotating shaft 34 are axially connected to the vertical plate 31, and a driving gear 35 meshing with the arc-shaped rack 32 is fixed on the rotating shaft 34.
[0024] When in use, the driving motor 33 drives the rotating shaft 34 to rotate, and the driving gear 35 on the rotating shaft 34 rotates to drive the arc-shaped rack 32 meshing with it to move. Since one side of the arc-shaped rack 32 is fixed to the roller 312 through the connecting rod 313, and the roller 312 is movably installed in the arc-shaped slide groove 311, the arc-shaped rack 32 can make an arc motion along the circumference of the forming drum, and then when the forming drum rotates, the arc-shaped rack 32 drives the filling valve mounting part 1 to move in an arc synchronously. Compared with the traditional fixed filling and horizontal follow-up structure, the arc-shaped follow-up structure of the utility model moves synchronously with the forming drum during filling, which is suitable for various shapes with complex shapes and short filling content discharge channels. The filling time is longer, which ensures the stability of the filling weight of different shapes.
[0025] like Figure 2 As shown, in the embodiment of the utility model, limit cover plates 314 are provided on both sides of the arc-shaped slide groove 311, and the limit cover plates 314 are provided with avoidance holes 315 for the connecting rod 313 to pass through, so as to avoid the risk of escaping from the slide groove when the arc-shaped slide groove 311 runs at high speed or is impacted by external force, so that the filling valve mounting part 1 can always move synchronously with the forming roller according to the predetermined arc trajectory, thereby ensuring the continuity and accuracy of the filling operation.
[0026] The two rollers 312 are connected to the two ends of the arc rack 32 by connecting rods 313 respectively. The two rollers 312 provide balanced support and guidance from the two ends of the arc rack 32, which can effectively disperse the force exerted on the arc rack 32 during movement, reduce the shaking, offset or jamming caused by uneven force at a single point, and make the arc rack 32 always maintain an accurate and smooth running trajectory when making an arc motion with the forming roller, ensure that the movement of the filling valve mounting part 1 is highly synchronized with the forming roller, thereby improving the filling accuracy and quality. Especially when dealing with packaging tasks with complex shapes and demanding filling requirements, it can effectively avoid filling errors caused by the instability of the arc rack 32, improve the consistency and stability of the filling weight of products with different shapes, and enhance the reliability and adaptability of the arc follower structure of the entire packaging machine.
[0027] Since the follower structure of the present invention is suspended above the forming roller, and the laminating operation needs to be performed on the forming roller, the follower structure needs to be able to translate above the forming roller to avoid the laminating operation. Specifically, the suspension fixing member 2 includes a translation connecting plate 21 connected and fixed to the upper end of the vertical plate 31, a slider 22 fixed on the translation connecting plate 21, a guide rail 23 for slidingly connecting the slider 22, and a translation mounting plate 24. The lower end surface of the translation mounting plate 24 is provided with a guide mounting plate 25 for connecting to the fixed guide rail 23, and the upper end surface of the translation mounting plate 24 is fixedly mounted on the bracket or shell of the equipment. When the follower structure needs to be translated to expose the forming roller below, by pushing the translation connecting plate 21, the slider 22 on the translation connecting plate 21 slides along the guide rail 23, so that the translation connecting plate 21 can easily drive the related structure below it to move, which is simple to operate and saves time and effort.
[0028] In order to limit and fix the static state of the suspension fixing part 2, a movable pin 241 is provided on the translation mounting plate 24 in the embodiment of the utility model, and a plurality of plug-in limiting holes 211 are arranged in a straight line on the translation connecting plate 21. The arrangement and extension direction of the plug-in limiting holes 211 are parallel to the guide rail 23, so as to prevent unnecessary displacement or shaking due to external force interference or equipment vibration during the operation of the equipment, thereby ensuring the position stability of the filling valve mounting part 1 connected thereto and the entire filling system.
[0029] Furthermore, a handle 242 is provided at the upper end of the latch 241, and the operator can quickly and accurately control the plugging state of the latch 241 through the handle 242, thereby realizing rapid limit fixation and release of the static state of the suspension fixture 2, greatly shortening the operation time and improving the operation efficiency.
[0030] like Figure 1 and Figure 3 As shown, in the embodiment of the utility model, the filling valve mounting part 1 is fixedly mounted on one end of the fixed plate 321, and the other end of the fixed plate 321 is provided with a fragrance bead feeding part 4, and the feeding direction of the fragrance bead feeding part 4 intersects with the filling direction of the filling valve on the forming roller. The filling valve mounting part 1 and the fragrance bead feeding part 4 are integrated into the same structural system, which is more efficient in space utilization, reduces the need for additional installation space, and makes the overall structure of the packaging machine more compact and simple. The feeding direction and the filling direction intersect on the forming roller, which can ensure that the fragrance beads are accurately added while the product is liquid filled. The two realize precise coordination in time and space, avoid uneven material addition or timing confusion caused by step-by-step operation or position deviation, and effectively improve the overall quality and production efficiency of the product.
[0031] It should be noted that in order to adapt to the different requirements of placing fragrance beads in products of different shapes, the feeding direction of the fragrance beads feeding part 4 in the embodiment of the present invention is adjustable. Through the adjustable feeding direction, the feeding path and landing point of the fragrance beads can be flexibly changed according to the specific product shape, and the fragrance beads can be accurately added to the predetermined position to ensure that each product can obtain the best fragrance beads distribution effect, thereby maximizing the function and fragrance release effect of the fragrance beads, and improving the quality consistency of the product and user experience.
[0032] The above description is only a preferred embodiment of the present application and does not constitute any form of limitation to the present application. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present application fall within the scope of the technical solution of the present application.
