Description

Technical Field

[0001] The utility model belongs to the field of film rolling machines, and in particular relates to a film rolling machine which is convenient for disassembly and assembly. Background Art

[0002] Film rolling machine is a device used to control the opening and closing of greenhouse covering materials (usually polyethylene film). This equipment is widely used in the agricultural field, especially in greenhouse planting. For the film, the film rolling machine is needed to complete the work of rolling up when not in use and unfolding when it is used again. At the same time, for industrial use, film rolling machines are also used on filter membranes, PI membranes and other materials.

[0003] To roll up the film, it needs to be collected and wound on the outside of the film roll. The film roll of the film roll machine is usually installed on a frame and is used to roll or unroll greenhouse covering materials (such as polyethylene film). It is usually inserted and then fixed by bolts or other mechanical structures.

[0004] A Chinese patent with authorization announcement number CN209259331U discloses an industrial film rolling machine, which includes a frame, an unwinding mechanism for supporting and unwinding a freshwater net roll, a filter rack for placing a filter, a gluing mechanism for gluing the filter, a mobile driving device, and a winding mechanism for rolling up the freshwater net and the filter on the freshwater net stand to form a filter element. The frame is provided with a freshwater net stand for supporting the freshwater net; the freshwater net unrolled by the unwinding mechanism is laid flat on the freshwater net stand; the filter rack is slidably mounted on the frame; the mobile driving device is arranged between the frame and the filter rack, so as to drive the filter rack forward by the mobile driving device to facilitate taking the filter and placing it on the freshwater net stand; and the filter rack is driven backward and reset by the mobile driving device to facilitate the gluing operation of the filter on the freshwater net stand by the gluing mechanism.

[0005] The above technical solution has the following defects:

[0006] The installation method of the film roll is the same as that of the existing equipment, which is to limit it by bolts or mechanical fixing mechanisms after insertion. Although this installation method is relatively stable in the fixing effect, it is necessary to remove the bolts or mechanical fixing mechanisms with tools during installation and disassembly, and then tilt the film roll to make one end of it disengage from the limit position and then take out the other end. The overall process is relatively cumbersome, which increases the time for disassembly and assembly. At the same time, the lack of auxiliary support structure makes the overall force point at the rotating ends of the film roll, which will cause bending or even breakage. Utility Model Content

[0007] In view of the above defects, the utility model provides a film rolling machine which is easy to disassemble and assemble, comprising a fixed base frame, a driving device installed on the fixed base frame and two film rolling cylinders driven by the driving device, the left and right sides of the fixed base frame are fixed with supporting side plates by bolts, the top of the two supporting side plates are provided with two first rotation grooves, the top of each of the supporting side plates is provided with a matching limiting mechanism, the top of the limiting mechanism is provided with a second rotation groove and is limited by inserting a limiting plate, the left and right rotating ends of the two film rolling cylinders are respectively located inside the two first rotation grooves and the two second rotation grooves in the same straight line, and the side surface of the two supporting side plates close to each other is also provided with an auxiliary supporting mechanism matched with the first rotation groove and the two second rotation grooves.

[0008] Furthermore, the limiting mechanism includes an inverted T-shaped plug plate, the second rotation groove is opened in the middle of the top of the plug plate, the limiting plate and the left and right sides of the plug plate are fixed by a matching locking mechanism, the bottom end of the plug plate is inserted into the interior of the two first rotation grooves respectively through two fixed limiting pressure rods, and the bottom ends of the limiting plate and the limiting pressure rod and the ends close to the second rotation groove and the first rotation groove are both arc surfaces that fit the rotation end of the film roll.

[0009] Through the above technical solution, complex structures such as bolts are abandoned in the fixing method of the film roll drum. The film roll drum installed on the side is limited by the deadweight of the top film roll drum, and the top film roll drum can be fixed by a simple locking mechanism, which greatly saves the time spent on disassembly and installation in subsequent disassembly and maintenance.

[0010] Furthermore, a first rotating pad and a second rotating pad are fixed to inner walls of the first rotating groove and the second rotating groove, respectively.

[0011] The above technical solution is used to protect the rotating end of the film roll to prevent noise from being generated due to rotation.

[0012] Furthermore, two groups of slots are provided at the top of the supporting side plate, and plug rods respectively matched with the two groups of slots are fixed at the bottom of the plug plate.

[0013] Through the above technical solution, not only can the insertion plate and the supporting side be fixed, but also the film roll inside the slot can be limited by inserting the insertion rod into the slot.

[0014] Furthermore, the auxiliary support mechanism includes three groups of telescopic grooves and three support plates. The three groups of telescopic grooves are opened on a side surface of the two supporting side plates close to each other, and are respectively located at the bottom of the two first rotating grooves and the second rotating grooves. Each group of telescopic grooves includes no less than five grooves. The inner bottom wall of each groove is fixed with an arc-shaped support plate by a spring. The inner wall of the support plate is inlaid with bearings distributed at equal distances, and the number of bearings corresponds to the number of grooves. A linkage column is fixed inside each bearing, and the outer surface of the linkage column is in contact with the outer ring of the adjacent film roll. The side of the support plate close to the supporting side plate is fixedly connected to each support plate by a group of fixing columns corresponding to the telescopic grooves.

[0015] Through the above technical solution, after the film roll is installed, both ends can be supported to disperse the force strength at the two ends (i.e., the first rotating groove and the second rotating groove), prevent the rotating end from bending or breaking, and provide better support.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] Compared with the traditional film rolling machine, the installation method abandons the traditional method of fixing the film roll by screws or other mechanical structures, and simplifies the installation steps by direct insertion. At the same time, the limiting method of the film roll at the lower part is fixed by the gravity of the film roll at the higher part, and the film roll at the higher part is fixed by a convenient locking mechanism, which simplifies the disassembly and assembly steps as a whole;

[0018] At the same time, an auxiliary support mechanism for auxiliary support of the film roll is added, which can disperse the force at both ends of the film roll to ensure the uniformity of the overall force and prevent bending and breaking at the rotating end. Films of different thicknesses can also be adapted through spring displacement. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The drawings provide embodiments of the device. However, the device can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "set" should be understood in a broad sense, for example, they can be fixedly connected or set, or detachably connected or set, or integrally connected or set. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] Example

[0026] like Figure 1-3 As shown, the present embodiment provides a film rolling machine which is easy to assemble and disassemble, comprising a fixed base frame 1, a driving device installed on the fixed base frame 1 and two film rolling drums 4 driven by the driving device (it can also be three, which are respectively installed inside two first rotating grooves 21 and one second rotating groove 8 for standby). Similar to the existing equipment, its driving device can be a motor driving a roller, and the roller is connected to the rotating end of the film rolling drum 4 through a conveyor belt (its rotating end is movably connected with the roller, and can be rotated without falling off by means of movable card connection, through prismatic card grooves and card blocks, such as the rotating end is a hexagonal prism, the inner ring of the roller is a hexagonal groove, etc., which will not be elaborated here). At the same time, the present embodiment is provided with two first rotating grooves 21 to adapt to the transmission needs in different directions, or if one side is damaged, the other side can be directly used without affecting the normal operating efficiency.

[0027] The left and right sides of the fixed base frame 1 are fixed with support side plates 2 by bolts, and the tops of the two support side plates 2 are provided with two first rotation grooves 21, and the top of each support side plate 2 is installed with a matching limit mechanism 3, and the top of the limit mechanism 3 is provided with a second rotation groove 8 and is inserted through the limit plate 6 for limiting. In this process, the limiting work of the film roll 4 installed inside the support side plate 2 is completed by the limit mechanism 3. The left and right rotation ends of the two film rolls 4 are respectively located inside the two first rotation grooves 21 and the two second rotation grooves 8 on the same straight line, and the side surface of the two support side plates 2 close to each other is also provided with an auxiliary support mechanism 5 matched with the first rotation groove 21 and the two second rotation grooves 8.

[0028] The limiting mechanism 3 includes an inverted T-shaped plug plate, and the second rotation groove 8 is opened in the middle of the top of the plug plate. The limiting plate 6 is fixed to the left and right sides of the plug plate by a matching locking mechanism 7. The locking mechanism 7 can be a common locking structure such as a hinge lock and a lock buckle, which is used to simply fix and lock the limiting mechanism 3 and the limiting plate 6 without additional tools, and will not be described in detail here. The bottom end of the plug plate is inserted into the inside of the two first rotation grooves 21 respectively through two fixed limiting pressure rods 31, and the bottom ends of the limiting plate 6 and the limiting pressure rod 31 and the ends close to the second rotation groove 8 and the first rotation groove 21 are all arc surfaces that fit with the rotation end of the film roll 4. The setting of the arc surface is used to fit the rotation end of the film roll 4 without affecting its normal rotation, and at the same time has good stability. The first rotating pad 22 and the second rotating pad 9 are fixed to the inner walls of the first rotating groove 21 and the second rotating groove 8 respectively. It should be noted that in order to improve the rotation stability and reduce the friction, the first rotating pad 22 and the second rotating pad 9 can be replaced by semicircular bearings (at the same time, the insertion ends of the limit pressure rod 31 and the limit plate 6 can also be installed with corresponding rotating pads or semicircular bearings).

[0029] Two groups of slots 23 are provided at the top of the supporting side plate 2, and plug rods 32 respectively adapted to the two groups of slots 23 are fixed to the bottom of the plug plate. The inserted plug rods 32 can limit the film roll 4 inside the slots 23 without affecting its rotation.

[0030] The auxiliary support mechanism 5 includes three groups of telescopic slots 51 and three support plates 54. The three groups of telescopic slots 51 are opened on the side of the two supporting side plates 2 close to each other, and are respectively located at the bottom of the two first rotating slots 21 and the second rotating slot 8, and are used to support the film rolls 4 of different heights. In order to ensure its load-bearing and supporting effects, each group of telescopic slots 51 includes no less than five channels, and the inner bottom wall of each channel is fixed with a curved contact ring 53 through a spring 52. The inner wall of the resistance ring 53 is inlaid with bearings 55 distributed at equal distances, and the number of bearings 55 corresponds to the number of grooves. A linkage column 56 is fixed inside each bearing 55, and the outer surface of the linkage column 56 is in contact with the outer ring of the adjacent film roll 4. The side of the support plate 54 close to the supporting side plate 2 is fixedly connected to each resistance ring 53 through a group of fixed columns corresponding to the telescopic groove 51. That is, while supporting and dispersing the load of the rotating end of the film roll 4, the film roll 4 can be synchronously rotated in a rotating state through each rotatable linkage column 56, and the friction force in a fixed state will not cause poor rotation effect of the film roll 4 when it rotates.

[0031] The present embodiment describes a film rolling machine that is easy to disassemble and assemble. When the film rolling drum 4 needs to be disassembled, the locking mechanism 7 is opened to separate the limit plate 6 from the limit mechanism 3 (i.e., the plug plate). At this time, the film rolling drum 4 located inside the second rotating groove 8 can be removed. Due to the lack of gravity pressure, the limit mechanism 3 (i.e., the plug plate) can be easily removed, and the separation of the limit mechanism 3 and the supporting side plate 2 is completed, and the film rolling drum 4 located inside the first rotating groove 21 can be taken out; otherwise, the installation operation can be completed.

[0032] It should be noted that the structure described in the utility model can be implemented in a variety of different forms and is not limited to the described embodiments. Any equivalent transformations made by ordinary technicians in this field using the contents of the utility model specification and drawings, or directly or indirectly applied to other related technical fields, such as the loading and unloading of other items, are included in the protection scope of the utility model.
