Description

Technical Field

[0001] This utility model belongs to the field of wood ear packaging technology, specifically, it relates to a wood ear packaging vacuum coating machine. Background Technology

[0002] With the popularization of healthy eating concepts, the demand for dried goods such as black fungus has increased, driving the upgrading of packaging equipment. By removing the air from the packaging of black fungus products, the oxygen content is reduced, inhibiting the growth of microorganisms and preventing food oxidation and spoilage. After vacuum packaging, the plastic film is precisely attached to the surface of the packaging to form a sealing layer, which enhances the moisture-proof and mildew-proof performance, while also improving the appearance and texture of the product.

[0003] The prior art discloses a vacuum packaging mechanism for beef (CN221068672U), including a workbench, a vacuum chamber, and a storage compartment. The vacuum chamber is connected to a vacuum pump assembly inside the workbench via a connecting pipe. A grid knife is provided on the right side of the workbench, and an automatic film covering mechanism is provided on the left side of the workbench. This invention fixes one end of the traction film to the outside of the winding roller, which automatically winds it up. When the outside of the winding roller is full of the waste material after film cutting, it also moves the uncut film to the top of the storage compartment, automatically covering the top of the plastic box with film. This solves the problem of the prior art where the film is manually tractioned to cover the surface of the beef for packaging, which is prone to wrinkles on the film surface due to operational errors, affecting the quality of the beef vacuum packaging.

[0004] Research revealed that existing technologies lack basic measures for flattening and smoothing the product, resulting in uneven distribution of the wood ear mushroom particles during vacuum packaging. This leads to gaps after film coating, resulting in poor sealing of the package and susceptibility to moisture and oxidation. Furthermore, during the coating process, pressure treatment is usually required to ensure the packaging film adheres to the packaging. However, existing technologies are not suitable for the fragile nature of dried wood ear mushrooms, which can easily cause the dried wood ear mushrooms to break or damage the film during the pressure coating process.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] A vacuum coating machine for packaging wood ear mushrooms, including

[0008] A workbench, the top of which is hinged to a vacuum chamber, and a connecting pipe connects the workbench and the vacuum chamber.

[0009] The averaging assembly is movably disposed within the workbench. The averaging assembly includes a placement platform, a toggle shaft, and a lifting column. The lifting column is fixedly disposed at the bottom of the placement platform, the toggle shaft is rotatably disposed inside the workbench, and the lifting column is sleeved on the toggle shaft. The placement platform is movably disposed on the workbench.

[0010] In a preferred embodiment of the present invention, a pressure frame is provided inside the bottom surface of the vacuum chamber, and multiple support shafts are arranged in an array inside the pressure frame. The feeding block is rotatably connected to the pressure frame through the support shafts.

[0011] In a preferred embodiment of this utility model, a motor is fixedly installed inside the workbench, the output end of the motor is connected to one end of the actuating shaft, the lifting column is located at the center of the bottom surface of the placement platform, a partition is fixedly installed inside the workbench, and the lifting column slides through the center of the partition.

[0012] In a preferred embodiment of this utility model, two vibration springs are symmetrically fixed to the bottom surface of the placement platform, and two guide cylinders are symmetrically fixed to the bottom surface of the partition. The guide cylinders are sleeved with vibration springs, and the placement platform is elastically connected to the worktable through the two vibration springs.

[0013] In a preferred embodiment of this utility model, an arc-shaped resisting plate is provided on each of the four sides of the interior of the placement platform. Multiple resisting springs are fixed in an array between the inner curved surface of the resisting plate and the placement platform. The placement platform is elastically connected to the resisting plate through the resisting springs.

[0014] In a preferred embodiment of the present invention, a guide roller and a double-ended lead screw are rotatably provided at one end of the worktable, the guide roller is located above the double-ended lead screw, and a film feeding roller is sleeved on the double-ended lead screw.

[0015] In a preferred embodiment of this utility model, a rotating wheel is fixedly provided at one end of the double-ended lead screw, and a clamping plate is threaded at each end of the double-ended lead screw. The bottom surface of the clamping plate slides in cooperation with the inner bottom surface of the workbench, and the two clamping plates together clamp and lock the film release roller.

[0016] Compared with the prior art, the present invention has the following advantages:

[0017] 1. By setting up a spreading component, the placement platform clamps and fixes the wood ear mushroom packaged products through the four-sided resistance plates. The ring on the actuating shaft is eccentrically set on the disc to push the lifting column. The ring drives the square column, which pushes the placement platform. The placement platform, through the up and down vibration of the vibration spring, drives the packaging to vibrate and spread the wood ear mushrooms evenly. This ensures that the wood ear mushroom particles are evenly distributed in the packaging, preventing the particles from breaking the packaging and solving the problems of poor sealing and easy moisture oxidation caused by the gaps between the particles.

[0018] 2. By setting up a four-pointed star structure material-pulling block, the rotation of the material-pulling block and the support shaft, combined with the thermoplastic pressure of the pressure frame, allows the rotating material-pulling block to pry open the protruding wood ear mushrooms, avoiding the crushing caused by squeezing the wood ear mushrooms and preventing the protruding dried wood ear mushrooms from breaking through the packaging film. The thermoplastic pressure of the pressure frame can thermoplastic seal the corners of the packaging, ensuring better sealing while vacuum packaging.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0028] A vacuum coating machine for packaging wood ear mushrooms, such as Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, including

[0029] The workbench 10 has a vacuum chamber 13 hinged to its top. A connecting pipe 18 connects the workbench 10 and the vacuum chamber 13. The vacuum chamber 13 is connected to the vacuum pump inside the workbench 10 through the connecting pipe 18. Multiple material feeding blocks 23 are rotatably arranged at the bottom of the vacuum chamber 13.

[0030] The averaging assembly is movably disposed within the worktable 10. The averaging assembly includes a placement platform 12, a toggle shaft 19, and a lifting column 29. The lifting column 29 is fixedly disposed at the bottom of the placement platform 12, the toggle shaft 19 is rotatably disposed inside the worktable 10, and the lifting column 29 is sleeved on the toggle shaft 19. The placement platform 12 is movably disposed within the worktable 10. Figure 1 and Figure 4 As shown, a pressure frame 24 is provided inside the bottom surface of the vacuum chamber 13, and multiple support shafts 22 are arranged in an array inside the pressure frame 24. The feeding block 23 is rotatably connected to the pressure frame 24 through the support shafts 22.

[0031] Specifically, the feeding block 23 has a four-pointed star structure and is rotatably connected to the support shaft 22 via bearings. All four corners of the feeding block 23 are arc-shaped. An electric heating plate is installed inside the pressure frame 24. Both the electric heating plate and the vacuum pump assembly are externally connected to control air cylinders. The control system controls the heating temperature of the electric heating plate inside the pressure frame 24 and the vacuum extraction volume of the vacuum pump assembly. A square cavity is opened on the top surface of the workbench 10, and the placement platform 12 is movably disposed within this cavity. The vacuum chamber 13 is a vacuum chamber. A plastic tray or plastic bag containing wood ear fungus is placed inside the placement platform 12. Then, a portion of the plastic film on the film-dispensing roller 15 is pulled out and placed on top of the plastic tray or plastic bag containing wood ear fungus. The vacuum chamber 13 needs to be filled. Then, the vacuum chamber 13 is rotated and placed on top of the placement platform 12. The vacuum pump assembly and the connecting pipe 18 work together to vent the air inside the vacuum chamber 13. Under vacuum, the heat generated by the electric heating plate in the pressure frame 24 group is sent into the vacuum chamber 13 through the exhaust vent to heat the entire membrane. Together, they achieve the effect of vacuum packaging. Open the vacuum chamber 13 and take out the packaged wood ear fungus. The rotation of the material pushing block 23 and the support shaft 22 can push the protruding wood ear fungus apart to avoid crushing caused by squeezing the wood ear fungus and to prevent the protruding dry wood ear fungus from breaking the packaging film. The thermoplastic pressure of the pressure frame 24 can thermoplastic seal the corners of the packaging, ensuring better sealing while vacuum packaging.

[0032] like Figure 3 and Figure 5 As shown, a motor 28 is fixedly installed inside the workbench 10. The output end of the motor 28 is connected to one end of the actuating shaft 19. The lifting column 29 is located at the center of the bottom surface of the placement platform 12. A partition 21 is fixedly installed inside the workbench 10. The lifting column 29 slides through the center of the partition 21.

[0033] like Figure 3 and Figure 5 As shown, two vibration springs 27 are symmetrically fixed to the bottom surface of the placement platform 12, and two guide cylinders 20 are symmetrically fixed to the bottom surface of the partition plate 21. The guide cylinders 20 are sleeved with the vibration springs 27, and the placement platform 12 is elastically connected to the worktable 10 through the two vibration springs 27.

[0034] like Figure 4 and Figure 5 As shown, an arc-shaped abutment plate 26 is provided on each of the four sides of the interior of the placement platform 12. Multiple abutment springs 25 are fixed in an array between the inner curved surface of the abutment plate 26 and the placement platform 12. The placement platform 12 is elastically connected to the abutment plate 26 through the abutment springs 25.

[0035] The working principle is as follows: the actuating shaft 19 consists of a long shaft and a disc, with the long shaft located off-center from the disc. The lifting column 29 consists of a square column and a ring, with the ring fitting around the disc. The partition 21 has a corresponding square hole in the center, through which the square column passes. A scraper is fixedly mounted on the top of the resistance plate 26. The motor 28 is connected to an external control system, which controls the speed and start of the motor 28. In use, the packaging bag or box containing the wood ear fungus is placed between the four resistance plates 26. The four resistance plates 26 adapt to the size of the packaging bag or box via their respective resistance springs 25. At this time, the four resistance plates 26 support the packaging bag or box. The clamping and control system drives the motor 28 to start. The motor 28 drives the long shaft of the actuating shaft 19 to rotate. The long shaft drives the disc to rotate. The rotating disc eccentrically pushes the ring. The ring drives the square column to rise and fall in the square hole. Simultaneously, two through holes are symmetrically opened on the partition plate 21. The inner ring of the guide cylinder 20 corresponds to the through hole. The vibration spring 27 passes through the through hole and vibrates elastically in the guide cylinder 20. At this time, the vibration springs 27 on both sides cooperate with the reciprocating lifting column 29 to vibrate up and down. At this time, the placement platform 12 is in a state of up and down vibration. At this time, the vibration is distributed in the packaging of the wood ear granules, gradually achieving uniform distribution, avoiding the granules from breaking the packaging, and solving the problems of poor sealing and easy moisture oxidation caused by the gaps between the granules.

[0036] like Figure 1 As shown, a guide roller 14 and a double-ended lead screw 16 are rotatably mounted on one end of the worktable 10. The guide roller 14 is located above the double-ended lead screw 16, and a film feeding roller 15 is sleeved on the double-ended lead screw 16.

[0037] like Figure 1 and Figure 2 As shown, a rotating wheel 11 is fixedly installed at one end of the double-ended lead screw 16, and a clamping plate 17 is threaded at each end of the double-ended lead screw 16. The bottom surface of the clamping plate 17 slides in cooperation with the inner bottom surface of the worktable 10, and the two clamping plates 17 together clamp and lock the film release roller 15.

[0038] The working principle is as follows: the clamping plate 17 is an arched plate with a threaded hole at the top and a flat bottom. A square groove is provided at one end of the worktable 10. A guide roller 14 is rotatably connected to the square groove through a bearing column. The guide roller 14 is used to guide the direction of the film. A square opening is provided on one side of the square groove. In use, the clamping plate 17 near the square opening is removed first. Then, the film-feeding roller 15 wrapped with plastic film is sleeved onto the double-ended screw 16 through the square opening. The removed clamping plate 17 is then tightened and reset onto the double-ended screw 16. The rotating wheel 11 is rotated to control the rotation of the double-ended screw 16. The double-ended screw 16 drives the clamping plates 17 at both ends to move relative to each other, so that the clamping plates 17 at both ends clamp the two ends of the film-feeding roller 15. This prevents the film-feeding roller 15 from slipping off the double-ended screw 16 or shifting position during the film feeding process, which would cause the plastic film coverage area to deviate from the position of the square cavity.

Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the protection scope of this utility model.
