Description

Technical Field

[0001] This utility model relates to the field of silver ear fungus processing technology, specifically a packaging machine capable of bilateral clamping and positioning. Background Technology

[0002] The processing of white fungus mainly includes raw material pretreatment and packaging. Packaging needs to balance product protection, airtight preservation, and efficiency. Existing equipment is generally semi-automatic or fully automatic: semi-automatic equipment requires manual placement of the white fungus, with mechanical positioning mechanisms securing the material; fully automatic equipment integrates material conveying and cutting processes, achieving unmanned operation through sensors and control systems. Core functions revolve around stable material fixation, precise membrane covering, heat sealing, and finished product separation, meeting the efficiency and standardization requirements of industrial production.

[0003] During the design process of this utility model, the following problems were discovered in the existing technology:

[0004] Existing packaging devices mostly use single-sided clamping or manual positioning, which can easily lead to material displacement and damage during the packaging process. In addition, the upper and lower film wrapping requires manual alignment, which is inefficient and results in poor adhesion. Furthermore, there is a lack of automatic recycling structure for waste film edges, which can easily lead to material waste and environmental problems. Overall, the level of automation is low. Utility Model Content

[0005] The purpose of this invention is to provide a packing machine capable of bilateral clamping and positioning, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a packaging machine capable of bilateral clamping and positioning, comprising a support mechanism, wherein an upper groove is provided in the middle of the top of the support mechanism, and an upper film winding mechanism is rotatably connected to the inner walls on both sides of the upper groove; a lower groove is provided in the middle of the bottom of the support mechanism, and a lower film winding mechanism is rotatably connected to the inner walls on both sides of the lower groove; fixing plates are provided on both sides of the bottom wall of the support mechanism, and clamping mechanisms are provided on the opposite sides of the two fixing plates; and heat sealing mechanisms are screwed to both sides of the top wall of the support mechanism.

The top wall of the support mechanism 1 is screwed with heat sealing mechanisms 8 on both sides.

[0022] In this embodiment, as Figure 1 and Figure 3 As shown, the support mechanism 1 includes an upper support plate 101. The four bottom corners of the upper support plate 101 are provided with the driving ends of hydraulic cylinders 102. The bottom ends of the four hydraulic cylinders 102 are screwed to the top four corners of the lower support plate 103. The surface of the upper support plate 101 is provided with an upper groove 2, and the surface of the lower support plate 103 is provided with a lower groove 4.

[0023] In this embodiment, as Figure 1 and Figure 2 As shown, the upper film winding mechanism 3 includes an upper take-up roller 301, one end of which is connected to a first motor 302, and an upper film 303 is sleeved on the outer wall of the upper take-up roller 301. The other end of the upper film 303 is sleeved on the outer wall of the upper unwind roller 304.

[0024] In this embodiment, as Figure 1 and Figure 2As shown, the lower winding film mechanism 5 includes a lower take-up roller 501, one end of which is connected to a second motor 502, and a lower film 503 is sleeved on the outer wall of the lower take-up roller 501. The other end of the lower film 503 is sleeved on the outer wall of the lower release roller 504.

[0025] In this embodiment, as Figure 4 As shown, the clamping mechanism 7 includes two first electric push rods 701, which are screwed to the opposite sides of the two fixed plates 6 respectively. The driving ends of the two first electric push rods 701 are provided with clamping plates 702, and the opposite sides of the clamping plates 702 are provided with silicone pads 703.

[0026] In this embodiment, as Figure 4 As shown, pressure sensors are installed at the drive ends of the two first electric actuators 701.

[0027] In this embodiment, as Figure 3 As shown, the heat sealing mechanism 8 includes two second electric push rods 801. The top ends of the two second electric push rods 801 are respectively screwed to the two sides of the top wall of the support mechanism 1. The driving end of the second electric push rod 801 is provided with a sealing plate 802, and the inner wall of the sealing plate 802 is fitted with an electric heating tube 803.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the working process of this double-sided clamping and positioning packaging machine is as follows:

[0029] First, the operator can place the silver ear fungus to be packaged flat on the surface of the lower film 503 in the lower support plate 103 in the lower film winding mechanism 5, so that it is located in the center position between the two clamping mechanisms 7. Then, through the external controller, the first electric push rod 701 on the two fixing plates 6 is activated at the same time, so that its driving end pushes the clamping plate 702 connected to it to move closer to each other inward until the silicone pad 703 on the inner side of the clamping plate 702 can gradually fit and contact the two sides of the silver ear fungus. At this time, the pressure sensor (Huba511) installed on the outer wall of the driving end of the first electric push rod 701 will monitor the clamping force in real time. When the pressure reaches the preset value, the pressure sensor (Huba511) will send a signal to the external control system and control the first electric push rod 701 to stop moving, thereby completing the stable clamping of the silver ear fungus on both sides.

[0030] After confirming that the silver ear fungus is properly clamped, the operator can simultaneously activate four hydraulic cylinders 102, causing the drive ends of the four hydraulic cylinders 102 to begin vertical extension and retraction, driving the connected upper support plate 101 and upper film winding mechanism 3 to descend synchronously until the upper film 303 in the upper film winding mechanism 3 can tightly adhere to the upper surface of the silver ear fungus. At this time, the upper film 303 and the lower film 503 will form symmetrical film layers, completely wrapping the clamped silver ear fungus in the middle. When the upper film 303 and the lower film 503 completely cover the silver ear fungus and exceed the predetermined length of the edge, the operator can activate both sides through the external controller. The second electric push rod 801 is activated, causing its drive end to move the connected sealing plate 802 downward. At the same time, the electric heating tube 803 on the inner wall of the sealing plate 802 is activated to heat it to the set temperature. During this period, the second electric push rod 801 will continue to press down until the sealing plate 802 presses the overlapping area of ​​the upper film 303 and the lower film 503. At this time, the electric heating tube 803 will transfer heat to the film surface, causing the upper film 303 and the lower film 503 to melt. Then, by maintaining pressure and temperature, the sealing is ensured to be completely bonded. Subsequently, the second electric push rod 801 drives the sealing plate 802 to reset, completing the film-side heat sealing.

[0031] After heat sealing is completed, the operator can use a blade to cut the upper film 303 and the lower film 503 laterally to separate the packaged tremella from the film roll. At the same time, the operator can start the first motor 302 and the second motor 502 simultaneously, so that they drive the interlocked upper unwinding roller 304 and lower unwinding roller 504 to continue rotating, thereby continuously winding and recycling the cut waste film edge, keeping the film roll path clean, and preparing for the next packaging.
