[0002] The barrel mold labeling fixture is a fixture used to insert labels into the mold cavity during the injection molding process of barrel products.
[0003] Currently, in-mold labeling and embedding fixtures for barrels fix the label seams after the labels are rolled up, making it impossible to automatically adjust the position of the label seams and meet the needs of label seam adjustments. In addition, the existing in-mold labeling and embedding fixtures for barrels have poor label stability, which affects the placement of the labels in the mold cavity and consequently affects the quality of barrel injection molding. Utility Model Content
[0004] To address the issues raised in the background section regarding the inability of existing barrel mold labeling and embedding fixtures to automatically adjust the position of label seams, thus failing to meet the needs for adjusting label seam variations, and the poor label stability of existing barrel mold labeling and embedding fixtures affecting the placement effect of labels within the mold cavity, this utility model achieves the following technical solution: a barrel mold labeling and embedding rotating fixture, comprising a fixture mounting plate and a PE mold, wherein a connecting plate is provided on the surface of the fixture mounting plate, and the PE mold is fixedly connected to the connecting plate;
[0005] A rotary cylinder is fixedly installed on the surface of the fixture mounting plate away from the connecting plate, and the rotary cylinder is used to drive and control the PE mold to rotate at a set angle.
[0006] Furthermore, the connecting plate is rotatably connected to the fixture mounting plate via bearings, and the rotary cylinder is provided with a rotating shaft inside, the output end of which is fixedly connected to the connecting plate.
[0007] Furthermore, a connecting ring is fixedly provided between the connecting plate and the PE mold, and a bent pipe joint is fixedly installed on the surface of the connecting ring. One end of the bent pipe joint is connected to the negative pressure equipment.
[0008] A semi-circular through groove is installed in the inner ring surface of the connecting ring, and the other end of the bent pipe joint is connected to the through groove.
[0009] Furthermore, the surface of the PE mold is provided with a number of through negative pressure holes, which are circumferentially distributed on the surface of the PE mold.
[0010] Furthermore, the outer surface of the PE mold is provided with a circular groove, which corresponds to the circumferentially distributed negative pressure holes.
[0011] Furthermore, at least two sets of PE molds are mounted on the surface of the fixture mounting plate via connecting plates.
[0012] Furthermore, the surface of the fixture mounting plate away from the connecting plate is fixedly provided with reinforcing rib one and reinforcing rib two.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. The label embedding and rotating fixture inside the barrel mold can achieve rotation control of the PE mold by setting a rotating cylinder in the fixture mounting plate and rotatably installing the connecting ring in the fixture mounting plate. This allows for adjustment of the position of the label seam on the PE mold surface to meet different label seam position requirements.
[0015] 2. The label-embedding rotating fixture inside the barrel mold, by setting negative pressure holes on the PE mold surface and grooves that cooperate with the circumferentially distributed negative pressure holes, can better roll the label onto the PE mold surface and improve the stability of the rolled label, thereby improving the quality of the surface pattern of the barrel product after injection molding.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] An example of the rotating fixture for attaching and embedding labels inside the barrel mold is as follows:
[0024] Please see Figures 1-5 A rotating fixture for labeling and embedding labels inside a barrel mold includes a fixture mounting plate 1 and a PE mold 4. One or more sets of PE molds 4 are mounted on the surface of the fixture mounting plate 1 through a connecting plate 2. The surface of the fixture mounting plate 1 is provided with a connecting plate 2, and the PE mold 4 is fixedly connected to the connecting plate 2.
[0025] A rotary cylinder 7 is fixedly installed on the surface of the fixture mounting plate 1 away from the connecting plate 2. The connecting plate 2 is rotatably connected to the fixture mounting plate 1 through a bearing. A rotary shaft 71 is provided inside the rotary cylinder 7. The output end of the rotary shaft 71 is fixedly connected to the connecting plate 2. The rotary cylinder 7 is used to drive and control the PE mold 4 to rotate at a set angle.
[0026] Specifically, the label is placed on the surface of the PE mold 4 of the embedding fixture. After the label is rolled up on the surface of the PE mold 4, the PE mold 4 is driven to rotate by the rotary cylinder 7. The PE mold 4 drives the seam of the label to rotate, thereby adjusting the position of the label seam so that it can be put into the mold cavity later.
[0027] Based on this, a connecting ring 3 is fixedly installed between the connecting plate 2 and the PE mold 4. A bent pipe joint 5 is fixedly installed on the surface of the connecting ring 3. One end of the bent pipe joint 5 is connected to a negative pressure device, which generates negative pressure in the internal cavity of the PE mold 4. A semi-circular through groove 6 is installed in the inner ring surface of the connecting ring 3. The other end of the bent pipe joint 5 is connected to the through groove 6. By setting the through groove 6, the negative pressure can be applied more evenly to the internal cavity of the PE mold 4.
[0028] The surface of the PE mold 4 has several through negative pressure holes 41. The negative pressure holes 41 are distributed circumferentially on the surface of the PE mold 4. The negative pressure in the cavity inside the PE mold 4 is used to make the label roll onto the outer surface of the PE mold 4.
[0029] It should be further explained that the outer surface of the PE mold 4 is provided with a circular groove 42, which corresponds to the circumferentially distributed negative pressure holes 41. When a negative pressure is generated inside the PE mold 4, the negative pressure can act in a ring shape in the groove 42 through the negative pressure holes 41 and the groove 42, so as to better roll the label on the surface of the PE mold 4 and improve the stability of the label after rolling.
[0030] Based on this, a first reinforcing rib 8 and a second reinforcing rib 9 are fixedly provided on the surface of the fixture mounting plate 1 away from the connecting plate 2, thereby strengthening the installation connection between the fixture mounting plate 1 and the robotic arm system.
[0031] Working principle of the rotating fixture for attaching and embedding labels inside the barrel mold:
[0032] First, place the label for the barrel mold on the surface of the positioning PE mold 4 of the embedded label fixture. When the negative pressure equipment is in the start-up state, negative pressure is generated inside the PE mold 4 through the bend joint 5 and the through groove 6. Utilize the negative pressure inside the PE mold 4 and cooperate with the negative pressure hole 41 and the groove 42 to make the label roll onto the outer surface of the PE mold 4.
[0033] When it is necessary to adjust the position of the label seam on the surface of PE mold 4, start the rotary cylinder 7. The rotary cylinder 7 drives the PE mold 4 to rotate through the rotary shaft 71, thereby adjusting the label seam to the set angle. Then, the label can be placed into the mold cavity through the PE mold 4. The label is adhered to the mold by electrostatic application. After the mold is injection molded, a product with a pattern is produced.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
