Description

Technical Field

[0001] The utility model relates to the technical field of grain film sealing, in particular to a handheld grain film single-groove tube sealing and grooving device. Background Art

[0002] Sealing the grain surface with a film is a characteristic traditional practice in the grain storage industry in China, and thus the "double-low" and "triple-low" grain storage technologies have been formed. The functions of sealing the grain surface with a film are as follows: 1. Solve the problems of poor airtightness of the original granary and incomplete insecticidal effect, and improve the fumigation effect; 2. The film can improve the airtightness of the granary, enabling the granary to apply green grain storage technologies such as controlled atmosphere, which can not only effectively prevent the occurrence of pests, but also maintain the storage quality of grains, and at the same time reduce the dosage of chemical agents and reduce the damage to the environment; 3. Sealing the grain surface can reduce the convection of external hot and humid air and the inside of the granary, which helps to maintain a stable grain storage ecosystem inside the granary; 4. Sealing and capping the grain surface in time at low temperature can inhibit the respiration of grains and the growth of insects and molds, which helps to maintain the fresh quality of grains.

[0003] The commonly used method for sealing grain films is as follows: First, fixedly install a single-groove tube with an annular closed card slot on the surface of the wall to be sealed, then lay the edge of the grain film (i.e., the film) on the single-groove tube, and finally use a sealing strip to seal and embed the four sides of the grain film in the card slot.

[0004] At present, a grooving device is usually used to seal the grain film. The commonly used grooving device is a handheld grain film single-groove tube sealing and grooving device, which includes a frame, a guide wheel and a grooving wheel. The guide wheel is rotatably connected and arranged on the right side of the bottom of the frame, and the grooving wheel is rotatably connected and arranged on the left side of the bottom of the frame. A sealing strip through hole is arranged on the right side wall of the frame. The guide wheel mainly plays a guiding role and at the same time presses the grain film into the card slot, which is convenient for the grooving wheel to press the sealing strip on the grain film. The grooving wheel is designed with a groove shape, which can just hold the sealing strip and press the sealing strip into the card slot. When the handheld grain film single-groove tube sealing and grooving device seals the grain film, the sealing strip is arranged through the sealing strip through hole, so that the grooving device is attached to the single-groove tube and moves along the extension direction of the single-groove tube to jointly squeeze the sealing strip and the grain film into the card slot, so that the edge of the grain film is sealed and clamped between the single-groove tube and the sealing strip. The sealing strip is an elastic rubber hose, and its shape is cylindrical. In order to ensure the stable installation of the grain film, the cross-sectional diameter of the sealing strip is often larger than the cross-sectional diameter of the single-groove card slot, and it is not convenient for the grooving device to squeeze the sealing strip into the card slot, resulting in low efficiency of grain film sealing and installation.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0023] The directions involved in the following text are based on Figure 1 the positions of each component in

[0024] Such as Figure 1 and Figure 2As shown, the utility model handheld grain film single groove tube sealing groove pressing device comprises a frame 1, a guide wheel 2 and a groove pressing wheel 3, the guide wheel 2 is rollingly connected and arranged on the right side of the bottom of the frame 1, the groove pressing wheel 3 is rollingly connected and arranged on the left side of the bottom of the frame 1, a sealing strip through hole 11 is arranged on the right side wall of the frame 1, a boosting and flattening clamping roller assembly is arranged in the middle of the frame 1, the boosting and flattening clamping roller assembly comprises a power part, a front rotating clamping roller 41 and a rear rotating clamping roller 42, the front rotating clamping roller 41 and the rear rotating clamping roller 42 are arranged vertically spaced, the front rotating clamping roller 41 is arranged on the front side of the rear rotating clamping roller 42, a sealing strip through cavity 43 is between the front rotating clamping roller 41 and the rear rotating clamping roller 42, and the sealing strip through hole 11 is connected with the sealing strip through cavity 43;

[0025] The power member can make the front rotating nip roller 41 rotate counterclockwise around its central axis, and the power member can make the rear rotating nip roller 42 rotate clockwise around its central axis.

[0026] When the handheld grain film single-groove tube sealing grooving pressing device of the utility model is used for grain film sealing installation, the power part is first controlled to work so that the front rotating clamping roller 41 and the rear rotating clamping roller 42 rotate; then the guide wheel 2 and the grooving pressing wheel 3 are clamped in the groove of the single-groove tube and move along the extension direction of the single-groove tube, and then the sealing strip is inserted into the sealing strip through hole 11 and sent into the sealing strip through cavity 43. The front rotating clamping roller 41 and the rear rotating clamping roller 42 clamp the sealing strip into a flat shape, and finally the grooving pressing wheel 3 squeezes the flattened sealing strip into the groove. The flattened sealing strip is easier to squeeze into the groove than the cylindrical sealing strip, which effectively improves the grain film sealing installation efficiency.

[0027] For example Figure 2 As shown, the power member can make the front rotating clamping roller 41 rotate counterclockwise around its center axis, and the power member can make the rear rotating clamping roller 42 rotate clockwise around its center axis. When the grain film seal is installed, when the sealing strip is sent into the sealing strip cavity 43, the rotation of the front rotating clamping roller 41 and the rear rotating clamping roller 42 can give the sealing strip a thrust to move in the direction of the pressing groove 3, making the sealing strip easier to move, reducing the resistance of the pressing groove device when moving, and thus making it easier for the pressing groove device to move along the extension direction of the single groove pipe. The pressing groove device is more convenient for the staff to use, can reduce the labor intensity of the staff, and further improves the efficiency of the grain film seal installation.

[0028] Specifically, the function of the power component is to rotate the front rotating pinch roller 41 and the rear rotating pinch roller 42. The front rotating pinch roller 41 and the rear rotating pinch roller 42 have the same structure. The front rotating pinch roller 41 and the rear rotating pinch roller 42 respectively include a central shaft and a rotating part. The central shaft is arranged in the exact middle of the rotating part, and the rotating part can rotate around the central shaft. To ensure the use effect of the power component, the preferred structure of the power component of the present utility model is: the power component includes a front reduction motor 44 and a rear reduction motor 45.

The power component can also be a combination of a motor and a transmission mechanism, as long as it can rotate the front rotating pinch roller 41 and the rear rotating pinch roller 42.

[0029] Since the rotation of the front rotating pinch roller 41 and the rear rotating pinch roller 42 can give the sealing strip a thrust force moving towards the pressing groove 3, making it easier for the sealing strip to move, the rotation speed of the front rotating pinch roller 41 and the rear rotating pinch roller 42 can adjust the moving speed of the sealing strip. For the convenience of the staff, the front reduction motor 44 and the rear reduction motor 45 are both frequency conversion motors. The frequency change of the front reduction motor 44 and the rear reduction motor 45 causes their rotational speed to change, thereby realizing the adjustment of the rotation speed of the front rotating pinch roller 41 and the rear rotating pinch roller 42. The staff can select the frequencies of the front reduction motor 44 and the rear reduction motor 45 according to the requirements of the installation rate.

[0030] One function of the front rotating pinch roller 41 and the rear rotating pinch roller 42 is to clamp the sealing strip into a flat shape. To clamp sealing strips with different diameters into a flat shape, the distance between the front rotating pinch roller 41 and the rear rotating pinch roller 42 can be adjusted. The staff adjusts the distance between the front rotating pinch roller 41 and the rear rotating pinch roller 42 according to the diameter of the sealing strip. Since the front rotating pinch roller 41 is connected to the front reduction motor 44 and the rear rotating pinch roller 42 is connected to the rear reduction motor 45, to facilitate the adjustment of the distance between the front rotating pinch roller 41 and the rear rotating pinch roller 42, a first strip-shaped hole in the front-rear direction and a second strip-shaped hole in the front-rear direction are provided in the middle of the frame 1.
