Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, specifically to a positioning and feeding structure for frozen product packaging in an automatic vacuum skin packaging machine with soft bottom film. Background Technology

[0002] The soft-bottom film automatic vacuum skin packaging machine is a device that uses a thin film as the bottom film for automatic vacuum skin packaging. It can be widely used in food packaging and can significantly reduce the packaging cost of vacuum skin packaging. However, because some foods are frozen before packaging, such as steaks and meat patties, their smooth surfaces after freezing make them prone to sliding and shifting between the food and the bottom film during automatic vacuum skin packaging. Therefore, a positioning mechanism is needed to pre-position them before packaging. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a frozen product positioning and feeding structure for an automatic vacuum skin packaging machine that addresses the shortcomings of the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A positioning and feeding structure for frozen product packaging in an automatic vacuum skin packaging machine with soft bottom film includes a servo module. A support plate is mounted on the slider of the servo module. A double-headed cylinder is mounted on the support plate. Two connecting arms, one long and one short, are mounted on the movable ends of the two sides of the double-headed cylinder. The ends of the connecting arms are connected to mounting plates. Clamps are mounted on the mounting plates. Guide rails are mounted on the support plate, and the clamps are connected to the corresponding guide rails.

[0006] Furthermore, the side of the clamp is provided with a clamping opening adapted to the frozen product packaging.

[0007] Furthermore, the clamps on the mounting plate are arranged in an alternating pattern.

[0008] Compared with the prior art, the automatic vacuum skin packaging machine for frozen products of this utility model has a positioning and feeding structure that uses clamps to hold the frozen product in place before feeding it into the skin packaging chamber for skin packaging. This solves the packaging quality problem caused by the displacement of the frozen product during transportation and improves the product packaging qualification rate. Attached Figure Description

[0012] The technical solutions in the embodiments of this utility model will be clearly and completely described below.

[0013] like Figure 1 and Figure 2 As shown, an automatic vacuum skin packaging machine for frozen products with a soft bottom film has a positioning and feeding structure, including a servo module 1. A support plate 2 is mounted on the slider of the servo module 1. A double-headed cylinder 3 is mounted on the support plate 2. Two connecting arms, one long and one short, are mounted on the movable ends of the two sides of the double-headed cylinder 3. The ends of the connecting arms are connected to a mounting plate. A clamp is mounted on the mounting plate. A guide rail is mounted on the support plate. The clamp is connected to the corresponding guide rail. The side of the clamp has a clamping opening adapted to the frozen product packaging. The clamps on the mounting plate are staggered.

[0014] In this embodiment, the servo module 1 adopts the CCM W40-10 dual-rail synchronous servo module. The slider of the W40-10 dual-rail synchronous servo module is equipped with a bracket plate 2. The movable ends of the double-headed cylinder 3 on both sides of the bracket plate 2 are respectively equipped with connecting arm 1 4 and connecting arm 2 5. The length of connecting arm 1 4 is greater than the length of connecting arm 2 5. The end of the connecting arm 1 4 is connected to the mounting plate 1 6, and the end of the connecting arm 2 5 is connected to the mounting plate 2 7. The mounting plate 1 6 is connected to three left-side clamps 8, which are located on both sides and in the middle of the mounting plate 1 6. The mounting plate 2 7 is connected to three right-side clamps 9, which are also located on both sides and in the middle of the mounting plate 2 7. The left-side clamps 8 and the corresponding right-side clamps 9 form a clamp. When the left-side clamps 8 and the right-side clamps 9 come together, they clamp and fix the packaged item.

[0015] In this utility model, the packaged item is a meat patty. Therefore, the left clamp 8 and the right clamp 9 are provided with arc-shaped clamping openings 10. The clamping openings are not limited to arc shapes, but can also be "V" shaped, square, etc. The shape of the clamping openings is adapted to the shape of the frozen product packaging.

[0016] The support plate 2 is equipped with two guide rails, one 11 and the other 12. The left clamps 8 on both sides of the mounting plate 6 are connected to the sliders on the guide rail 11. The left clamp 8 in the middle of the mounting plate 6 has an extension end at its tail, which is connected to the slider on the guide rail 12 through a pad 13. The right clamps 9 on both sides of the mounting plate 7 are connected to the sliders on the guide rail 11. The right clamp 9 in the middle of the mounting plate 7 is also connected to the slider on the guide rail 12 through a pad 13. In this way, the left clamps 8 and the right clamps 9 are staggered, which avoids interference between the left clamps 8 and the right clamps 9 when the piston end of the double-headed cylinder 3 is working.

[0017] In operation, the positioning and feeding structure for frozen food packaging of this utility model uses a double-headed cylinder 3 to control the clamp to hold the pre-positioned packaged item, and then the servo module 1 guides the item into the skin packaging chamber along with the film. The clamp then exits the skin packaging chamber and the skin packaging is performed.

[0018] This utility model is not limited to the embodiments described. Those skilled in the art can still make some modifications or changes without departing from the spirit and scope of this utility model. Therefore, the scope of protection of this utility model shall be determined by the scope defined in the claims.
