Abstract
Description
Technical Field
[0001] This utility model belongs to the field of chrysanthemum processing, and in particular relates to a chrysanthemum packaging machine. Background Technology
[0002] To extend the shelf life and freshness of free-flowing solid granular materials such as chrysanthemums, facilitate storage, and better meet the needs and uses of different consumers, chrysanthemums on the market are often packaged in small bags. The general procedure involves first weighing the chrysanthemums, then packing the measured chrysanthemums into thin film inner bags to achieve proper packaging.
[0003] Before packaging chrysanthemums into inner bags, the packaging film is first longitudinally sealed by a longitudinal sealing mechanism, then quantitatively fed into the bags via a feed tube. After bagging, a transverse sealing mechanism completes the transverse sealing. During this process, the packaging film is pulled by a traction mechanism. In existing technology, the traction mechanism includes two traction wheels, with the front end of the packaging film inserted between them. Since the distance between the two traction wheels is generally difficult to adjust, the front end of the packaging film is usually directly inserted into the two traction wheels during installation. This operation is cumbersome, the traction wheels are unstable when pulling the packaging film, and it cannot adapt to packaging films of different thicknesses. Utility Model Content
[0004] In view of the above problems, the purpose of this utility model is to provide a chrysanthemum packaging machine, which aims to solve the problems that the existing chrysanthemum packaging machine is not stable enough when pulling the packaging film and cannot adapt to packaging films of different thicknesses.
[0005] The present invention adopts the following technical solution:
[0006] The chrysanthemum packaging machine includes a frame, on which a winding rack, a guide cylinder, a horizontal sealing mechanism, and a feeding rack are sequentially arranged. A traction mechanism and a longitudinal sealing mechanism are respectively arranged on the frame opposite the guide cylinder. The traction mechanism includes a traction frame, on which a pair of traction seats are slidably arranged. A pair of upper and lower traction wheels are rotatably arranged on the traction seats, and a traction belt is fitted between the same pair of traction wheels. The traction frame also has a pair of clamping cylinders for driving the traction seats to slide. A traction assembly is provided inside the frame, including a pair of commutators coaxially connected. The output shaft of each commutator has a universal joint connected to the shaft of the lower traction wheel on the same side. A drive motor for driving either commutator to rotate is also provided inside the frame.
[0007] Furthermore, a pair of short slots are provided on the front side of the frame, and the axle of the lower traction wheel is located in the corresponding short slot.
[0008] Furthermore, the horizontal sealing mechanism includes a fixed frame, on which a pair of front and rear sliding seats are slidably mounted, and a horizontal sealing heating plate is mounted on the sliding seats. A pair of left and right linkage discs are mounted on the fixed frame, and a pair of linkage rods are rotatably mounted on the linkage discs. The two linkage rods are respectively rotatably mounted on the corresponding sliding seats. A horizontal sealing cylinder is provided on the back of the fixed frame, and the drive shaft of the horizontal sealing cylinder is mounted on the rear sliding seat.
[0009] Furthermore, the horizontal sealing heating plate has an elongated groove, and the front side of the fixing frame is provided with a push cylinder. The drive shaft of the push cylinder is provided with a toothed bar, and the toothed bar is located in the corresponding elongated groove.
[0010] Furthermore, the longitudinal sealing mechanism includes a mounting frame, a mounting plate on the mounting frame, a slide on the mounting plate, a longitudinal sealing heating plate on the slide, the longitudinal sealing heating plate being positioned towards the guide cylinder, and a longitudinal sealing cylinder on the mounting plate, the drive shaft of the longitudinal sealing cylinder being connected to the slide.
[0011] The beneficial effects of this utility model are as follows: When the inner bag film passes through the traction mechanism, the inner bag film is first pressed tightly against the guide cylinder, and the two sides of the inner bag film overlap, with the overlapping position facing the longitudinal sealing mechanism. The two clamping cylinders simultaneously drive the traction seat to move inward until the two traction belts clamp the inner bag film. Then, the traction assembly drives the two lower traction wheels on the left and right to rotate simultaneously. Under the linkage of the traction belts, the two pairs of traction wheels rotate and drive the inner bag film to move downward along the guide cylinder. In this device, the position of the two traction belts can be finely adjusted by the clamping cylinders, which can accommodate inner bag films of different thicknesses, and the whole adjustment process is relatively simple.

[0017] To make the purpose, technical solution, and advantages of this utility model patent clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0018] To illustrate the technical solution described in this utility model, specific embodiments are described below.
[0019] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.
[0020] Combination Figure 1-3 As shown, the chrysanthemum packaging machine includes a frame 1, on which a winding rack 2, a guide cylinder 3, a horizontal sealing mechanism, and a feeding rack 4 are sequentially arranged. A traction mechanism and a longitudinal sealing mechanism are respectively arranged on the frame 1 opposite the guide cylinder 3. The traction mechanism includes a traction frame 5, on which a pair of traction seats 6 are slidably arranged. A pair of upper and lower traction wheels are rotatably arranged on the traction seats 6, with the upper traction wheel marked 71 and the lower traction wheel marked 72. A traction belt 8 is fitted between the pair of traction wheels. The traction frame 5 also has a pair of clamping cylinders 9, which are used to drive the traction seats 6 to slide. A traction assembly is provided inside the frame 1, which includes a pair of commutators 10. The two commutators 10 are coaxially connected, and the output shaft of the commutator 10 is provided with a universal joint 11. The universal joint 11 is connected to the shaft of the lower traction wheel 72 on the same side. A drive motor 12 for driving either commutator 10 to rotate is also provided inside the frame 1.
[0021] To extend the shelf life and freshness of free-flowing solid granular materials such as chrysanthemums, this packaging machine can be used to package chrysanthemums. In this embodiment, an unwinding wheel is rotatably mounted on the unwinding frame, and an inner bag film roll is mounted on the unwinding wheel. When packaging chrysanthemums using this packaging machine, the inner bag film first adheres tightly to the guide tube, passes through the traction mechanism, and under the traction of the traction mechanism, sequentially passes through the longitudinal sealing mechanism and the transverse sealing mechanism to form the current inner packaging bag with an opening. Chrysanthemums are quantitatively loaded into the current inner packaging bag through the guide tube. The traction mechanism continues to pull the inner bag film downwards for a certain distance, and the transverse sealing mechanism performs transverse heat sealing on the opening of the current inner packaging bag, simultaneously forming the next inner packaging bag with an opening.
[0022] In this device, the traction mechanism is used to pull the inner bag film. The traction mechanism includes a traction frame, on which a pair of left and right traction seats are slidably provided. On the traction seats, a pair of upper and lower traction wheels are rotatably provided. A traction belt is sleeved between the pair of traction wheels.
[0023] As the inner bag film passes through the traction mechanism, the two traction belts move a short distance away from the guide cylinder. First, the inner bag film is pressed tightly against the guide cylinder, with both sides of the film overlapping, the overlap point directly opposite the longitudinal sealing mechanism. Two clamping cylinders simultaneously drive the traction seat to move inward until the two traction belts clamp the inner bag film. Then, the traction assembly drives the two lower traction wheels to rotate simultaneously. Under the linkage of the traction belts, the two pairs of traction wheels rotate, moving the inner bag film downward along the guide cylinder. In this device, the position of the two traction belts can be finely adjusted using the clamping cylinders, which not only accommodates inner bag films of different thicknesses but also simplifies the entire adjustment process.
[0024] Figure 3 In this design, a pair of short slots 13 are formed on the front side of the frame 1, and the shaft of the lower traction wheel 72 is located in the corresponding short slot 13. When the traction assembly simultaneously drives the two lower traction wheels to rotate, the drive motor starts working. Since the two commutators are coaxially connected, when the drive motor drives the input shaft of the corresponding commutator to rotate, the output shafts of the two commutators rotate simultaneously. Under the linkage of the universal joint, the two lower traction wheels rotate simultaneously, and the inner bag film is pulled downward by the traction belt. At the same time, when the two clamping cylinders drive the traction seat on the same side to slide laterally on the traction frame, the shaft of the lower traction wheel can move along the length of the short slot under the action of the universal joint.
[0025] In this structure, such as Figure 2 The longitudinal sealing mechanism includes a mounting frame 14, a mounting plate 15 on the mounting frame 14, a slide 16 on the mounting plate 15, a longitudinal sealing heating plate 17 on the slide 16, the longitudinal sealing heating plate 17 being positioned toward the guide cylinder 3, and a longitudinal sealing cylinder 18 on the mounting plate 15, the drive shaft of the longitudinal sealing cylinder 18 being connected to the slide 16.
[0026] When the longitudinal sealing mechanism is used to longitudinally seal the overlapping positions of the two sides of the inner bag film, the longitudinal sealing cylinder drives the slide to move towards the guide cylinder until the longitudinal sealing heating plate presses to the overlapping position. After the longitudinal sealing heating plate achieves longitudinal heat sealing of the inner bag film to form an inner packaging bag with an opening, the material can be quantitatively fed into the inner packaging bag through the guide cylinder.
[0027] As a preferred structure, Figure 4-5 The horizontal sealing mechanism includes a fixed frame 19, on which a pair of front and rear slide seats 20 are slidably mounted. A horizontal sealing heating plate 21 is mounted on the slide seats 20. A pair of left and right linkage discs 22 are mounted on the fixed frame 19. A pair of linkage rods 23 are rotatably mounted on the linkage discs 22. The two linkage rods 23 are respectively rotatably mounted on the corresponding slide seats 20. A horizontal sealing cylinder 24 is provided on the back of the fixed frame 19. The drive shaft of the horizontal sealing cylinder 24 is mounted on the rear slide seat 20.
[0028] After the chrysanthemums are placed inside the inner packaging bag, it is then pulled forward by the traction belt to the horizontal sealing mechanism for horizontal heat sealing. During horizontal heat sealing, the horizontal sealing cylinder drives the rear slide block to slide forward a short distance on the fixed frame. During this process, the two rear linkage rods push the two linkage discs to rotate in the same direction. Then, under the action of the linkage discs, the two front linkage rods pull the front slide block to move backward. That is, the front and rear slide blocks slide in the same direction until the two horizontal sealing heating plates clamp the inner packaging bag, thus achieving horizontal heat sealing of the inner packaging bag.
[0029] As a specific structure, such as Figure 5 The horizontal sealing heating plate 21 has an elongated groove 25. A pushing cylinder 26 is located on the front side of the fixing frame 19. The drive shaft of the pushing cylinder 26 has a toothed strip 27, which is positioned within the corresponding elongated groove 25. After the two horizontal sealing heating plates clamp the inner packaging bag, achieving a horizontal heat seal, the pushing cylinder pushes the toothed strip towards the packaging bag until it is positioned within the elongated groove of the other horizontal sealing heating plate. At this point, the inner packaging bag is sealed. The toothed strip creates an easy-tear toothed surface on the packaging bag, facilitating subsequent opening and forming an inner packaging bag with an opening. The packaging bag then falls onto the unloading rack for unloading.
[0030] 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 and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
