Description

Technical Field

[0001] The invention relates to the technical field of longan packaging, and in particular to longan meat packaging equipment. Background Art

[0002] Longan needs to be sealed in individual packaging to prevent moisture from affecting product quality. During the packaging process, a combination scale is used to weigh the longan of a set weight and individually package it for easy transportation and sale.

[0003] During the packaging process, the bag straps are curled to overlap the two sides of the bag, and then heat-sealed. However, due to misalignment, the two sides of the bag are misaligned, resulting in substandard heat seals. This can cause air leaks during transportation, which can cause the longans to become damp. Summary of the Invention

[0004] The invention aims to provide a longan meat packaging device, which can make the edges of both sides of the packaging bag overlap well and avoid misalignment between the two, thereby improving the heat sealing quality of the two and avoiding air leakage.

A number of accommodating grooves are provided on the outer wall of the discharge barrel, and a contoured insert is hinged in the accommodating groove. The top of the contoured insert is hinged to the top of the accommodating groove, and a compression spring is provided between the inner wall of the contoured insert and the bottom of the accommodating groove. The outer wall of the contoured insert corresponds to the shape of the outer wall of the discharge barrel, and the outer wall of the contoured insert is provided with a spiral guide strip. The spiral guide strip of the contoured insert located on the left side of the bag edge gap rotates in the opposite direction to the contoured insert located on the right side of the bag edge gap, and the spiral guide strip gradually deviates from top to bottom toward the direction close to the bag edge gap.

[0007] Specifically, four accommodating grooves are opened on the outer wall of the discharge barrel, and the four accommodating grooves are evenly distributed along the circumference of the discharge barrel. There are two accommodating grooves on the left and right sides of the bag edge seam. The spiral guide strips of the contoured inserts provided in the two accommodating grooves on the left have opposite rotation directions to those of the contoured inserts provided in the two accommodating grooves on the right.

[0008] Specifically, the spiral guide strip is made of silicone material, and the height of the spiral guide strip beyond the outer wall of the contoured insert is 1-2 mm.

[0009] Specifically, the contour of the accommodating groove is a trapezoid that is thin at the top and thick at the bottom, so that the accommodating groove is divided into an upper groove section and a lower groove section. The bottom of the lower groove section is connected to the outer wall of the discharge barrel. Accordingly, the cross-section of the lower section of the contoured insert is D-shaped.

[0010] Specifically, the transverse side edges of the cone are inclined from the back to the front, and the bag belt roller for discharging the bag belt is arranged below the rear side edge of the cone.

[0011] Specifically, two heat-pressing bag-sealing plates are hinged on the front side of the base, and the lower end of the discharge barrel is located on the upper side of the gap between the two heat-pressing bag-sealing plates.

[0012] Specifically, the inner wall of the heat-sealing bag plate is provided with a U-shaped heat-sealing strip.

[0013] Specifically, two bag-pulling clamping wheels are provided on the front side of the base.

[0014] Specifically, a bag cutting mechanism is provided on the front side of the base.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] See Figures 3 to 6 The bagging roller 3 for discharging the bagging tape 9 is located below the rear edge of the cone 42. The bagging tape 9, which has been discharged from the bagging roller 3, climbs upward along the rear wall of the cone 42 and wraps around the outer wall of the cone 42. The bagging tape 9 passes around the upper opening edge and the edge of the V-shaped notch of the cone 42 and enters the gap between the discharge barrel 21 and the belt reel 4. The two side edges of the bagging tape 9 pass through the bag edge slits 43, thus bending the bagging tape 9 into a roll and surrounding the discharge barrel 21. The bent and rolled bagging tape 9 passes through the support plate 1 through the perforation 11.

[0017] See Figure 1 、 Figure 2 Two bag-pulling wheels 7 jointly grip the rear edge of the bag strip 9 and intermittently pull the rolled bag strip 9 downward. As the rolled bag strip 9 passes through the two heat-pressing and sealing plates 6, they clamp together, allowing the U-shaped heat-sealing strip 61 to seal the bag strip 9, forming individual packages one after another. The individual packages are then cut and separated by the bag-cutting mechanism 8. A front-end combination scale weighs the longans to a set weight and feeds them into the receiving hopper 22. The longans are then fed into the heat-sealed individual bags through the discharge cylinder 21.

[0018] The two sides of the bag strip 9 passing through the bag edge seam 43 are overlapped, and the overlapped edges are subsequently sealed by heat pressing with a U-shaped heat sealing strip 61. In order to ensure that the two overlapped edges are better overlapped and avoid misalignment between the two, the outer wall of the discharge barrel 21 is provided with four receiving grooves 211 (combined with Figures 7 to 9 ), four receiving grooves 211 are evenly distributed along the circumference of the discharge barrel 21, with two receiving grooves 211 each located on the left and right sides of the bag edge slit 43. When the rolled bag strip 9 passes through the four contoured inserts 5, the inner wall of the bag strip 9 is pressed against by the four contoured inserts 5 (compression springs are provided between the inner walls of the contoured inserts 5 and the bottoms of the receiving grooves 211), forcing the spiral guide strips 51 into close contact with the bag strip 9. The spiral guide strips 51 of the contoured inserts 5 in the two left receiving grooves 211 rotate in opposite directions from those in the two right receiving grooves 211. This ensures that the spiral guide strips 51 on both sides smooth and guide the bag strip 9 toward the bag edge slit 43, ensuring that both sides of the bag strip 9 have sufficient width to pass through the bag edge slit 43, allowing the two sides to overlap better, preventing misalignment and ensuring more reliable subsequent heat sealing.

The upper opening edge of the conical cylinder 42 corresponds to the shape of the upper opening edge of the tape reel 4 and is fixedly connected, and a bag passing gap is left between the inner wall of the tape reel 4 and the outer wall of the discharge barrel 21. A bag edge slit 43 is provided on the front side of the tape reel 4, the upper end of the bag edge slit 43 extends to the V-shaped notch, and the lower end of the bag edge slit 43 extends to the bag edge upper opening 41.

[0043] The outer wall of the discharge barrel 21 is formed with a plurality of receiving slots 211, within which are hingedly connected contour inserts 5. The top of the contour inserts 5 is hingedly connected to the top of the receiving slots 211, and a compression spring (not shown) is installed between the inner wall of the contour inserts 5 and the bottom of the receiving slots 211. The outer wall of the contour inserts 5 corresponds to the outer wall of the discharge barrel 21 and is provided with spiral guide strips 51. The contour inserts 5 located to the left of the bag edge slit 43 have the opposite rotational direction as the contour inserts 5 located to the right of the bag edge slit 43. The spiral guide strips 51 gradually deviate from top to bottom toward the bag edge slit 43.

[0044] Specifically, four accommodating grooves 211 are opened on the outer wall of the discharge barrel 21, and the four accommodating grooves 211 are evenly distributed along the circumference of the discharge barrel 21. There are two accommodating grooves 211 on the left and right sides of the bag edge seam 43. The spiral guide strips 51 of the contoured inserts 5 provided in the two left accommodating grooves 211 have an opposite rotation direction to the contoured inserts 5 provided in the two right accommodating grooves 211.

[0045] Specifically, the spiral guide strip 51 is made of silicone material, and the height of the spiral guide strip 51 beyond the outer wall of the contoured insert 5 is 1-2 mm.

[0046] Specifically, the contour of the accommodating groove 211 is a trapezoid that is thin at the top and thick at the bottom, so that the accommodating groove 211 is divided into an upper groove section and a lower groove section. The bottom of the lower groove section is connected to the outer wall of the discharge barrel 21. Accordingly, the cross-section of the lower section of the contoured insert 5 is D-shaped.

[0047] Specifically, the transverse side edges of the cone 42 are inclined from the back to the front, and the bag belt roller 3 for discharging the bag belt 9 is arranged below the rear side edge of the cone 42.

[0048] Specifically, two heat-pressing bag-sealing plates 6 are hingedly connected to the front side of the base, and the lower end of the discharge barrel 21 is located at the upper side of the gap between the two heat-pressing bag-sealing plates 6 .

[0050] Specifically, two bag-pulling clamping wheels 7 are provided on the front side of the base.

[0051] Specifically, a bag cutting mechanism 8 is provided on the front side of the base.

[0052] The working principle of the present invention is as follows:

[0053] See Figures 3 to 6 The bagging roller 3 for discharging the bagging tape 9 is located below the rear edge of the cone 42. The bagging tape 9, which has been discharged from the bagging roller 3, climbs upward along the rear wall of the cone 42 and wraps around the outer wall of the cone 42. The bagging tape 9 passes around the upper opening edge and the edge of the V-shaped notch of the cone 42 and enters the gap between the discharge barrel 21 and the belt reel 4. The two side edges of the bagging tape 9 pass through the bag edge slits 43, thus bending the bagging tape 9 into a roll and surrounding the discharge barrel 21. The bent and rolled bagging tape 9 passes through the support plate 1 through the perforation 11.

[0054] See Figure 1 、 Figure 2 Two bag-pulling wheels 7 jointly grip the rear edge of the bag strip 9 and intermittently pull the rolled bag strip 9 downward. As the rolled bag strip 9 passes through the two heat-pressing and sealing plates 6, they clamp together, allowing the U-shaped heat-sealing strip 61 to seal the bag strip 9, forming individual packages one after another. The individual packages are then cut and separated by the bag-cutting mechanism 8. A front-end combination scale weighs the longans to a set weight and feeds them into the receiving hopper 22. The longans are then fed into the heat-sealed individual bags through the discharge cylinder 21.

[0055] The two sides of the bag strip 9 passing through the bag edge seam 43 are overlapped, and the overlapped edges are subsequently sealed by heat pressing with a U-shaped heat sealing strip 61. In order to ensure that the two overlapped edges are better overlapped and avoid misalignment between the two, the outer wall of the discharge barrel 21 is provided with four receiving grooves 211 (combined with Figures 7 to 9 ), four receiving grooves 211 are evenly distributed along the circumference of the discharge barrel 21, with two receiving grooves 211 each located on the left and right sides of the bag edge slit 43. When the rolled bag strip 9 passes through the four contoured inserts 5, the inner wall of the bag strip 9 is pressed against by the four contoured inserts 5 (compression springs are provided between the inner walls of the contoured inserts 5 and the bottoms of the receiving grooves 211), forcing the spiral guide strips 51 into close contact with the bag strip 9. The spiral guide strips 51 of the contoured inserts 5 in the two left receiving grooves 211 rotate in opposite directions from those in the two right receiving grooves 211. This ensures that the spiral guide strips 51 on both sides smooth and guide the bag strip 9 toward the bag edge slit 43, ensuring that both sides of the bag strip 9 have sufficient width to pass through the bag edge slit 43, allowing the two sides to overlap better, preventing misalignment and ensuring more reliable subsequent heat sealing.

Although the present invention has been disclosed as above in terms of preferred embodiments, they are not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
