Description

Technical Field

[0001] The utility model relates to a horizontal winding machine. Background Art

[0002] A horizontal winding machine makes the packaging material (usually winding film) rotate around the object moving forward at a constant speed through a rotary arm system. At the same time, the tension of the packaging material is adjusted through a stretching mechanism to package the object into a fastened whole and form a regular spiral packaging on the surface of the object.

[0003] During the use of the existing horizontal winding machine, a pressing mechanism is usually adopted to press the object to be packaged to prevent the object from moving during the winding process and affecting the packaging effect. However, the existing horizontal winding machine can only package objects with the same size. Thus, the use of this horizontal winding machine is limited. Especially in the packaging of valve boxes, there are many types and sizes of existing valve boxes, with the minimum size being 380 mm and the maximum size being 1200 mm, and the existing horizontal winding machine cannot meet the packaging of valve boxes with the above sizes at the same time. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a horizontal winding machine with wide applicability.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A horizontal winding machine includes a winding machine body, a pressing mechanism arranged on the winding machine body, and a cutting assembly arranged on one side of the winding cavity. The pressing mechanism is divided into two groups located on both sides of the winding machine body respectively. At least one of the pressing mechanisms includes a fixed seat fixed on the winding machine body, a cylinder installed on the fixed seat, a positioning plate arranged below the fixed seat, a moving plate arranged below the positioning plate, and a pressing block installed below the moving plate. A long hole extending along the axis of the winding cavity is formed on the positioning plate. A stud is arranged on the moving plate and passes through the long hole. A locking nut is arranged on the stud. The plunger of the cylinder passes through the fixed seat to be connected to the positioning plate.

[0006] Further, a first relative position and a second relative position are configured between the positioning plate and the moving plate. When configured as the first relative position, at least part of the pressing block is located inside the winding cavity. When configured as the second relative position, the pressing block is located outside the winding cavity.

[0007] Further, the pressing mechanism further includes a guiding assembly. The guiding assembly includes sleeves fixed on the fixed seat and located on both sides of the cylinder, and guiding rods passing through the sleeves and penetrating the fixing plate to be connected to the positioning plate.

[0008] Further, the pressing block includes a columnar body.

[0009] Further, the pressing block further includes an elastic part covering the columnar body.

[0010] Further, the horizontal winding machine further includes a conveying mechanism at least partially located in the winding cavity of the winding machine body. The conveying mechanism includes a conveying component at least partially located in the winding cavity and a power source for driving the conveying component to operate. The conveying component includes a roller set driven by the power source and a conveyor belt sleeved on the roller set.

[0011] Further, the roller set includes two sets arranged oppositely, and two conveyor belts are arranged in parallel on each roller set.

[0012] Further, the conveying mechanism further includes two transmission components. The power source is located between the two transmission components. The two transmission components and the two roller components are arranged in a one-to-one correspondence to transmit the power of the power source to the roller components.

[0013] Further, the cutting component is located between the two transmission components.

[0014] Further, the cutting component includes a fixed bracket, a driving part fixed on the fixed bracket, a hook plate arranged on the driving part, and a cutting knife installed on the fixed bracket.

In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] In order to ensure the stability of the pressed packages, existing horizontal winding machines need to adopt two pressing mechanisms to press at different points of different packages. However, since the distance between the two pressing mechanisms is rated, this structure can only adapt to packages of the same specification. Therefore, the prior art cannot meet the requirement of packaging different specifications of packages with horizontal winding machines of multiple different specifications. To solve this problem, the present application provides a horizontal winding machine that can package packages of different specifications.

[0026] Please refer to Figures 1 to 3 , the horizontal winding machine of a preferred embodiment of the present application includes a winding machine body 10, a pressing mechanism 20 provided on the winding machine body 10, a conveying mechanism for pushing the package to move, and a cutting assembly 30 provided on one side of the winding cavity 11 of the winding machine body 10. The structure of the winding machine body 10 adopts the prior art and will not be described in detail herein.

[0027] The pressing mechanism 20 is divided into two groups located on both sides of the winding machine body 10 respectively. The structures of the two groups of pressing mechanisms 20 can be the same or different. In this embodiment, the structures of the two groups of pressing mechanisms 20 are different, and the two groups of pressing mechanisms 20 are respectively defined as a first pressing mechanism 21 and a second pressing structure 22.

[0028] Specifically, the first pressing mechanism 21 includes a first fixing seat 211 fixed on the winding machine body 10, a first cylinder 212 installed on the first fixing seat 211, a first positioning plate 213 provided below the first fixing seat 211, a moving plate 214 provided below the first positioning plate 213, and a first pressing block 215 installed below the moving plate 214. In this embodiment, the first pressing block 215 includes a columnar body (not labeled) and an elastic part (not labeled) covering the columnar body. In this embodiment, by setting the first pressing block 215 as a columnar body, when the packaged item moves, it will drive the first pressing block 215 to rotate, so that the first pressing block 215 always presses the transported item, which is convenient for positioning and packaging. The elastic part is provided to avoid rigid contact when the first pressing block 215 presses. A long hole 217 extending along the axis of the winding cavity 11 is formed on the first positioning plate 213, and a stud 218 passing through the long hole 217 is provided on the moving plate 214. A locking nut (not labeled) is provided on the stud 218. Through the setting of the stud 218, the square hole 217 and the locking nut, when the position of the moving plate 214 needs to be adjusted, the locking nut is loosened, and then the moving plate 214 is pushed to move along the axial direction. When it moves to a suitable position, the locking nut is tightened, so as to realize the adjustment of the position of the moving plate 214. The plunger of the first cylinder 212 passes through the fixing seat 211 to connect to the first positioning plate 213.

[0029] The second pressing mechanism 22 includes a second fixed seat 221 fixed on the winding machine body 10, a second cylinder 222 mounted on the second fixed seat 221, a second positioning plate 223 disposed below the second fixed seat 221, and a second pressing block 224 disposed below the second positioning plate 223. Similarly, the second pressing block 224 includes a columnar body and an elastic part (not labeled) covering the columnar body, and the first pressing block 224 can also rotate along with the packaged article being pressed.

[0030] By providing the first positioning plate 213 and the moving plate 214, the pressing mechanism 21 adopted by the horizontal winding machine enables the moving plate 214 to move relative to the first positioning plate 213, so as to adjust the position of the first pressing block 215 in the axial direction of the winding cavity 11, enabling it to press packages of different sizes (such as valve boxes), thus making the horizontal winding machine more applicable.

[0031] In this embodiment, a first relative position and a second relative position are configured between the first positioning plate 213 and the moving plate 214; when configured in the first relative position, the first pressing block 215 is at least partially located inside the winding cavity 11; when configured in the second relative position, the first pressing block 215 is located outside the winding cavity 11. In other embodiments, the first positioning plate 213 and the moving plate 214 can also be arranged to move along the direction perpendicular to the axis of the winding cavity 11.

[0032] In one embodiment, the first pressing mechanism 21 further includes a guiding component 219 (which can be called the first guiding component). The guiding component 219 includes sleeves 2191 fixed on the fixed seat 211 and located on both sides of the first cylinder 212, and guiding rods 2192 passing through the sleeves 2191 and penetrating the first fixing plate 211 to connect with the first positioning plate 213. By means of this guiding component 219, the moving plate 214 can move smoothly downward. The second pressing mechanism is also provided with a guiding component (which can be called the second guiding component 225).

[0033] The conveying mechanism includes a first conveying mechanism (not shown) and a second conveying mechanism (not shown) located on both sides of the winding machine body 10. The first conveying mechanism and the second conveying mechanism can adopt rollers in the prior art, and no detailed description will be given to the first conveying mechanism and the second conveying mechanism here. The first conveying mechanism and the second conveying mechanism are respectively driven by independent motors.

[0034] It should be noted that in the prior art, the horizontal winding machine realizes the movement of the object to be packaged through the first conveying mechanism and the second conveying mechanism. However, since there is a large distance between the first conveying mechanism and the second conveying mechanism, the horizontal winding machine in the prior art is more suitable for the movement of long-strip objects to be packaged. For rectangular objects to be packaged such as valve boxes, when the valve box enters the winding cavity 11, the contact surface between the first conveying mechanism, the second conveying mechanism and the valve box is small. Therefore, the driving force of the first conveying mechanism and the second conveying mechanism on the valve box will be reduced, and it is easy to occur that the valve box moves smoothly or even stays in the winding cavity 11.

[0035] To solve this problem, in this embodiment, the conveying mechanism further includes a third conveying mechanism 40 at least partially located in the winding cavity 11 of the winding machine body 10, and the third conveying mechanism 40 is located between the first conveying mechanism and the second conveying mechanism. The third conveying mechanism 40 further includes a third conveying component 41 at least partially located in the winding cavity 11 and a power source 42 for driving the third conveying component 41 to operate. The third conveying component 41 includes a roller group 411 driven by the power source 42 and a conveyor belt 412 sleeved on the roller group 411. The roller group 411 includes two relatively arranged groups, and two conveyor belts 412 are arranged in parallel on each roller group 411. The roller group 411 has a driving roller (not shown), a driven roller 4111 and a tensioning wheel (not shown), and the driving roller is located at the rear lower part of the driven roller 4111 ( Figure 1 In the direction indicated by the arrow a in the figure is the moving direction of the object to be packaged, and the front and rear directions of the horizontal winding machine are based on the moving direction of the object to be packaged). In this embodiment, the number of driven rollers 4111 is several. By arranging a plurality of driven rollers 4111, the supportability of the conveyor belt 412 can be increased, so that when the pressing mechanism 21 presses the object to be packaged, the lower part of the object to be packaged is supported.

[0036] The third conveying mechanism 40 further includes two transmission components 43. The power source 42 is located between the two transmission components 43. The two transmission components 43 and the two roller groups 411 are arranged in a one-to-one manner to transmit the power of the power source 42 to the roller groups 411. In this way, the structure of the third conveying mechanism 40 is made compact. The power source 42 is a motor. The third conveying mechanism 40 is fixed on the housing of the winding machine body 10 through a fixing frame 50.

[0037] Please combine Figures 3 to 5, the cutting assembly 30 is fixed on the fixing bracket 50. The cutting assembly 30 is located between two sets of transmission assemblies 43 and is arranged above the power source 42. With this arrangement, the overall structure of the horizontal winding machine is more compact. Specifically, in an optional embodiment, the cutting assembly 30 includes a fixed bracket 31, a driving member 32 fixed on the fixed bracket 31, a hook plate 33 arranged on the driving member 32, and a cutting knife 34 installed on the fixed bracket 31. The driving member 32 drives the hook plate 33 to move along the axis direction of the winding cavity 11. The cutting knife 34 faces the hook plate 33. The hook plate 33 has a hook portion 331 for hooking the winding tape, and a cutting groove 332 for the cutting knife 34 to insert is formed on the hook portion 331. In this embodiment, the driving member 32 is a cylinder. The cutting assembly 30 further includes a moving cover plate 35. The hook plate 33 is fixed on the front side of the moving cover plate 35. The rear side of the moving cover plate 35 is open, and the moving cover plate 35 covers the driving member 32. Through the moving cover plate 35, not only can the driving member 32 be shielded, but also the hook plate 33 can move smoothly.

[0038] It should be noted that the first conveying mechanism is located in front of the third conveying mechanism 40, and there is an aisle between them for the cutting assembly 30 to grab the packaging material. The second conveying mechanism is located behind the first conveying mechanism. The rollers of the second conveying mechanism are located above the cutting assembly 30 and the power source 42, and shield the cutting assembly 30 and the power source 42, so as to minimize the distance between the third conveying mechanism 40 and the second conveying mechanism.

[0039] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0040] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
