Description

Technical Field

[0001] This utility model belongs to the field of rolling machine technology, and more specifically relates to a pre-coating packaging rolling machine. Background Technology

[0002] Traditional film rolling machines typically use a film support above or behind the rolling mechanism to hold the roll of film. During packaging, two motor-driven pressure rollers are needed to clamp the film and pull it into the rolling mechanism so that the film ends can smoothly enter. At the same time, the two rollers need to move away from or towards each other to clamp or release the film. The structure is complex and requires advanced control programs for automation, resulting in high overall equipment costs. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a pre-coating and rolling packaging machine that simplifies the film packaging structure, reduces automated control, and lowers equipment costs.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a pre-coating packaging roll-up machine, comprising a conveying mechanism located in front of the roll-up machine body and a film support located above the conveying mechanism, wherein a roll of film is disposed on the film support, a rotatable first pressure roller is disposed on the conveying mechanism, a lifting drive device is connected to the first pressure roller, the first pressure roller is an independent segmented type or a whole roll, and a liftable film cutter is disposed in the roll-up machine body near the entrance of the roll-up mechanism.

[0005] Furthermore, the conveying mechanism includes a support and a conveyor belt located on the support, with the first pressure roller located at one end of the conveyor belt near the winding mechanism.

[0006] Furthermore, the conveying mechanism includes a support and a placement plate located on the support. The first pressure roller is located at one end of the placement plate near the winding mechanism. A second pressure roller corresponding to the first pressure roller is provided on the support, and a rotation drive mechanism is connected to the second pressure roller.

[0007] Furthermore, the membrane support includes a support rod, two support plates located on the support rod, and a placement rod between the two support plates. The roll film is rotatably sleeved on the placement rod, and the support plates and the support rod are adjustablely connected.

[0008] Furthermore, the first pressure roller is provided with a rough friction surface.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: the conveying mechanism sends the product to be rolled into the rolling mechanism for rolling, and during the product conveying process, the end of the roll film is located below the first pressure roller above the product. After the product is rolled, the first pressure roller descends and rotates, which can press the film and pull the film at the same time and send it into the rolling mechanism, thereby covering the surface of the rolled product with film. After multiple layers of packaging film are wrapped around the product, the film cutter descends to cut the film. By setting the roll film on the conveying mechanism, i.e. in front of the rolling mechanism, the film packaging structure is simplified, the automation control is reduced, and the equipment cost is reduced.

[0015] Reference Figure 1 and Figure 2 The present invention will be further described below.

[0016] Example 1:

[0017] A pre-coating packaging roll-up machine includes a conveying mechanism located in front of the roll-up machine body and a film support located above the conveying mechanism. A roll of film is disposed on the film support. A rotatable first pressure roller is disposed on the conveying mechanism. A lifting drive device is connected to the first pressure roller. The first pressure roller is an independent segmented type or a whole roll. A liftable film cutter is disposed in the roll-up machine body near the entrance of the roll-up mechanism.

[0018] like Figure 1 As shown, the conveying mechanism feeds the product to be rolled into the rolling mechanism for rolling. During the conveying process, the end of the roll film is located below the first pressure roller above the product. After the product is rolled, the first pressure roller descends and rotates, pressing and pulling the film while feeding it into the rolling mechanism, thus applying film to the surface of the rolled product. After multiple layers of packaging film are wrapped around the product, the film cutter descends to cut the film. By placing the roll film on the conveying mechanism, i.e., in front of the rolling mechanism, the film packaging structure is simplified, automation control is reduced, and the equipment cost is lowered.

[0019] Specifically, the roll film is positioned in front of the winding mechanism, and its winding direction on the product is opposite to that of the roll film positioned above or behind the winding mechanism.

[0020] like Figure 1 As shown in this example, preferably, the conveying mechanism includes a support and a conveyor belt located on the support, with the first pressure roller located at one end of the conveyor belt near the winding mechanism.

[0021] Specifically, when the first pressure roller presses down, the packaging film is clamped between the conveyor belt and the first pressure roller, and the forward movement of the conveyor belt can also drive the first pressure roller to rotate.

[0022] Specifically, the support frame is equipped with a transmission mechanism that drives the conveyor belt to move in a circular motion.

[0023] Specifically, conveyor belts are suitable for conveying thinner products, such as stickers and posters.

[0024] like Figure 1 As shown in this example, preferably, the membrane support includes a support rod, two support plates located on the support rod, and a placement rod between the two support plates. The roll film is rotatably sleeved on the placement rod, and the support plates and the support rod are adjustablely connected.

[0025] Specifically, the two support plates are fixedly connected by a connecting plate, and the connecting plate and the support rod can be slidably and fixedly connected, thereby changing the winding position of the roll film on the product.

[0026] like Figure 1As shown, in this example, preferably, the first pressure roller is provided with a rough friction surface to increase the friction when conveying the packaging film.

[0027] In this preferred embodiment, the membrane cutter is connected to a lifting drive mechanism. The membrane cutter is a long strip with a serrated or flat blade. The lifting drive mechanism can be a pneumatic cylinder, a hydraulic cylinder, or an electric telescopic rod.

[0028] In this example, preferably, the film cutter can also be disc-shaped. When it is disc-shaped, it is rotatably connected to the cutter holder. The cutter holder is slidably connected to the winding machine body and is driven to reciprocate to cut the film by means of a cylinder or motor plus chain.

[0029] In this preferred embodiment, the winding machine body is provided with a winding mechanism, which includes at least three rotating winding rollers, and the winding rollers are provided with multiple spaced winding wheels or an integral winding wheel.

[0030] In this example, the roll film material is preferably a transparent or opaque film, tape, or other self-adhesive material.

[0031] In this preferred embodiment, an auxiliary feeding roller is provided between the winding mechanism and the conveying mechanism, and a lifting mechanism is connected to the auxiliary feeding roller. The auxiliary feeding roller is either segmented and independent or a single piece.

[0032] In this example, the specific structure of the coiling machine body can also be referenced from the invention patent with publication number CN116040370A.

[0033] Example 2:

[0034] A pre-coating packaging roll-up machine includes a conveying mechanism located in front of the roll-up machine body and a film support located above the conveying mechanism. A roll of film is disposed on the film support. A rotatable first pressure roller is disposed on the conveying mechanism. A lifting drive device is connected to the first pressure roller. The first pressure roller is an independent segmented type or a whole roll. A liftable film cutter is disposed in the roll-up machine body near the entrance of the roll-up mechanism.

[0035] like Figure 2 As shown, in another preferred embodiment of the conveying mechanism, the conveying mechanism includes a support and a placement plate located on the support. The first pressure roller is located at one end of the placement plate near the winding mechanism. A second pressure roller corresponding to the first pressure roller is provided on the support, and a rotation drive mechanism is connected to the second pressure roller.

[0036] Specifically, the product is placed on the placement plate and manually fed into the winding mechanism for winding. At this time, the film is located between the first pressure roller and the second pressure roller. The first pressure roller descends and cooperates with the second pressure roller to clamp the packaging film. The rotating drive mechanism drives the second pressure roller to rotate, which in turn feeds the mold into the winding mechanism.

[0037] Specifically, the flatbed is suitable for manually conveying thicker products, such as carpets.

[0038] like Figure 2 As shown, the membrane support includes a support rod, two support plates located on the support rod, and a placement rod between the two support plates. The roll film is rotatably sleeved on the placement rod, and the support plates and the support rod are adjustablely connected.

[0039] Specifically, the support plate and the support rod are connected by bolts and nuts. After disassembly, the distance between the two support plates can be adjusted, and then placement rods of corresponding lengths can be used to place rolls of film of different widths.

[0040] The other technical features in this example are the same as those in Embodiment 1.
