Description

Technical Field

[0001] The utility model relates to the technical field of tools, and particularly relates to an auxiliary tool for sealing a grain storage plastic film. Background Art

[0002] In the grain storage industry, ensuring the safety and quality of grains is a crucial task. As the main place for grain storage, the sealing performance of a grain storage bin is directly related to the preservation effect of grains.

[0003] In the traditional sealing method of grain storage bins, plastic film sealing is widely used because of its low cost and relatively simple operation. However, in the actual operation process, there are many disadvantages in relying solely on manual labor for plastic film sealing.

[0004] Firstly, the manual sealing efficiency is low. For large grain storage bins, it takes a lot of time and manpower to complete the laying and sealing of the plastic film. This not only increases the labor cost but also may affect the timely storage of grains due to the long construction period.

[0005] Secondly, the quality of manual sealing is difficult to guarantee. During the sealing process, due to the instability of manual operation, problems such as uneven laying of the plastic film and gaps at the sealing joints are likely to occur. These problems may cause air, moisture, and pests to invade the bin, thus affecting the storage quality of grains and even causing losses such as mildew and insect damage of grains.

[0006] The patent with the patent application number CN202023007110.0 specifically discloses a sealing pliers, which includes a first pliers body and a second pliers body hinged by a hinge shaft. A guide sleeve is vertically fixed on the upper end surface of the hinge shaft, and fixed rollers are vertically fixed on the pliers heads of the first pliers body and the second pliers body respectively. The fixed rollers and the guide sleeve are on the same side of the pliers body of the sealing pliers. The structure of this sealing pliers is simple. When pressing a rubber groove pipe into the groove opening of a sealing groove plate, the operation is safe, convenient, and has high working efficiency.

[0007] However, the existing technical solutions still have the following technical problems:

[0008] Using this sealing pliers requires the operator to have certain skills and experience. Since the sealing process requires accurately pressing the rubber groove pipe into the groove opening of the sealing groove plate, high requirements are imposed on the control of the operation force and angle. If the operator is not proficient, it may lead to poor sealing effect or even damage to the sealing components.

[0009] For some key components, such as the hinge shaft, it may be necessary to regularly add lubricating oil to ensure its flexibility and durability. This increases the difficulty and cost of maintaining the sealing pliers.

[0010] Therefore, there is an urgent need for an auxiliary tooling that has wide applicability, is simple and flexible to operate, reduces manpower input, and ensures the tightness and stability of the plastic film seal. Utility Model Content

[0011] In view of the above problems, the utility model provides an auxiliary tooling for installing grain storage sealing strips. This tooling is equipped with a pressure wheel and a limit ring on the mounting seat, wherein the limit ring is located on one side of the mounting seat and can limit the sealing strip. A groove is provided at the contact portion between the pressure wheel and the sealing strip. During operation, the groove will squeeze and resist the sealing strip, so that the pressure wheel can better drive the sealing strip when rolling, ensuring that the sealing strip can be stably embedded in the mounting groove, thereby improving the sealing effect.

[0012] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0013] A grain storage plastic film sealing auxiliary tooling, comprising a mounting seat, a handle, a pressure wheel, a limiting ring and a handle;

[0014] The longitudinal section of the mounting seat is in a U-shaped configuration, and the mounting seat semi-encloses the pressing wheel;

[0015] The handle is mounted on the top of the mounting seat, and a space for an operator to hold is formed between the handle and the mounting seat;

[0016] The pressing wheel is rotatably mounted on the mounting seat, the lower end of the pressing wheel is arranged lower than the mounting seat, and the pressing wheel rolls along the sealing strip to embed the sealing strip into the mounting groove;

[0017] The limiting ring is connected to the mounting seat, and the limiting ring is extended from the pressing wheel to the front side of the pressing wheel along the pressing path of the sealing strip;

[0018] The handle is horizontally arranged on one side of the mounting seat, and the handle is staggered with the handle. The handle cooperates with the handle for an operator to hold and operate.

[0019] As an improvement, the circumferential edge of the pressure wheel in contact with the sealing strip is inwardly recessed and provided with a groove, and the groove is provided to press against the sealing strip.

[0020] As an improvement, the pressure wheel is rotatably connected to the mounting seat via a screw shaft, and fasteners are provided at both ends of the screw shaft.

[0021] As an improvement, the limiting ring includes a mounting portion, an extending portion and a limiting portion;

[0022] The mounting portion is sleeved on the screw shaft;

[0023] The extension part is arranged to connect the installation part and the limiting part;

[0024] The limiting part is arranged in a ring shape, and the sealing strip passes through the limiting part.

[0025] As an improvement, the handle is connected to the mounting seat by threaded fit. Nuts are fixedly arranged on both sides of the mounting seat, and external threads are arranged on the outer wall of one end of the handle connected to the nuts.

[0026] As an improvement, an auxiliary pressing wheel is arranged at the rear side of the pressing wheel. The lower end of the auxiliary pressing wheel is flush with the lower end of the pressing wheel. The auxiliary pressing wheel is rotatably mounted on the mounting seat through a connecting shaft, and fixing pieces are arranged at both ends of the connecting shaft.

[0027] As an improvement, both the pressing wheel and the auxiliary pressing wheel are located on one side of the mounting seat.

[0028] The beneficial effects of the present utility model are as follows:

[0029] (1) The rotational design of the pressing wheel and the setting that its lower end is lower than the mounting seat can enable the sealing strip to be smoothly embedded into the installation groove. The groove of the pressing wheel further enhances the extrusion effect on the strip. The auxiliary pressing wheel can re-compact and arrange the sealing strip processed by the pressing wheel, making the sealing strip more firm in the installation groove and having a better sealing effect;

[0030] (2) The design that the pressing wheel and the auxiliary pressing wheel are located on one side of the mounting seat enables the tooling to be smoothly operated in narrow spaces such as the edge of the wall, meeting the requirements for the installation of the sealing strip in special working scenarios. At the same time, during the operation of the tooling, the pressing wheel and the auxiliary pressing wheel are respectively in contact with the operation surface, forming a multi-point support structure. Through the cooperation of the auxiliary pressing wheel and the pressing wheel, it is ensured that the tooling always maintains balance during dynamic operation and avoids shaking;

[0031] (3) The limiting ring composed of the installation part, the extension part and the limiting part can guide the sealing strip into the correct position in advance and limit its left and right offset. During the operation process, it can ensure that the sealing strip is always pressed into the installation groove along the correct path, avoiding problems such as offset and distortion of the sealing strip during the installation process, thereby ensuring a good sealing effect. In addition, when it is necessary to adjust the position of the limiting ring according to different sizes of the sealing strip or different operation scenarios, the position of the limiting ring can be quickly adjusted by adjusting the fastening piece, improving the packaging quality and efficiency;

[0032] (4) The holding space formed by the handle and the mounting base, as well as the staggered design of the handle and the grip, conform to ergonomics, facilitating the operator to hold and apply force. It can reduce hand fatigue during long-term operation. By applying force to the handle and the grip with both hands respectively, the operator can more flexibly control the movement direction, speed, and strength of the tooling, improving the operation efficiency.

[0033] (5) Traditional manual installation of the sealing strip is time-consuming and laborious, while this tooling can quickly and continuously press the sealing strip into the sealing groove, greatly shortening the time of the sealing operation and improving the work efficiency.

[0034] In summary, the utility model has the advantages of improving work efficiency, ensuring sealing quality, being convenient to operate, and having strong applicability, and is especially suitable for the field of tool technology. Description of the Drawings

[0046] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, the meaning of "a plurality" is two or more, unless otherwise specifically defined.

[0047] Embodiment 1:

[0048] As Figures 1-5 shown, a storage grain plastic film sealing auxiliary tooling includes:

[0049] A mounting base 1, a handle 2, a pressure wheel 3, a limiting ring 4 and a handle 5;

[0050] The longitudinal section of the mounting base 1 is arranged in a U-shape. The U-shaped arrangement can ensure that the mounting base 1 provides good supporting force in both the horizontal and vertical directions. During the operation, even if it is subjected to forces in different directions, the overall structure integrity of the tooling can be maintained and it is not easy to deform;

[0051] The mounting base 1 semi-surrounds the pressure wheel 3. The pressure wheel 3 can rotate flexibly in this semi-surrounded space, and at the same time is restricted by the two side edges of the mounting base 1 to prevent the pressure wheel 3 from shaking excessively in the left and right directions or disengaging from the mounting position. And the opening part of the mounting base 1 is convenient for the operator to observe the contact situation between the pressure wheel 3 and the sealing strip and the process of the sealing strip being embedded in the mounting groove. The operator can timely adjust the operation angle and force to ensure the smooth progress of the sealing work;

[0052] The handle 2 is mounted on the top of the mounting seat 1, and a space for the operator to hold is formed between the handle 2 and the mounting seat 1. The handle 2 is connected to the mounting seat 1 by welding. Welding can ensure that the handle and the mounting seat have extremely high connection strength. Since the handle 2 is located at the top of the mounting seat, when the operator holds the handle 2 and applies downward pressure, the force can be transmitted to the mounting seat 1 and the pressure wheel 3 more evenly, thereby ensuring that the pressure wheel 3 can apply sufficient and stable pressure to the sealing strip, so that the sealing strip can be smoothly embedded in the mounting groove;

[0053] The pressing wheel 3 is rotatably mounted on the mounting seat 1, and the lower end of the pressing wheel 3 is arranged lower than the mounting seat 1, and the pressing wheel 3 rolls along the sealing strip to embed the sealing strip into the mounting groove. The rolling of the pressing wheel 3 can make the sealing strip evenly stressed during the embedding process, avoiding local excessive extrusion or insufficient embedding. Compared with sliding, the rolling method can reduce the wear on the surface of the sealing strip, thereby ensuring the integrity and sealing of the sealing strip.

[0054] The limiting ring 4 is connected to the mounting seat 1, and the limiting ring 4 is extended from the pressing wheel 3 to the front side of the pressing wheel 3 along the pressing path of the sealing strip. During operation, when the sealing strip moves in front of the pressing wheel 3, the limiting ring 4 can guide the sealing strip in advance, and when the sealing strip is pressed by the pressing wheel 3, the limiting ring 4 limits the movement of the strip in the left and right directions, thereby ensuring that the sealing strip is always pressed into the mounting groove along the correct path, thereby improving the accuracy and quality of the sealing work;

[0055] The handle 5 is horizontally arranged on one side of the mounting base 1, and the handle 5 and the handle 2 are staggered, and the handle 5 and the handle 2 cooperate with each other for the operator to operate and hold. When the handle 5 and the handle 2 are used in conjunction, the horizontally arranged handle 5 can help stabilize the lateral movement of the tooling and prevent the tooling from shaking left and right.

[0056] Among them, the circumferential edge of the pressure wheel 3 that contacts the sealing strip is recessed inwardly to form a groove 31, and the groove 31 is configured to squeeze and resist the sealing strip. When the pressure wheel 3 rolls along the sealing strip, the groove 31 squeezes and resists the sealing strip. Due to the presence of the groove 31, the sealing strip is subjected to pressure from various directions of the inner wall of the groove when contacting the pressure wheel 3. This multi-directional pressure enables the sealing strip to fit more closely in the groove 31, and can more effectively embed the sealing strip into the mounting groove compared to the contact between the pressure wheel and the strip in a plane.

[0057] Further, the pressing wheel 3 is rotationally connected to the mounting base 1 through a screw shaft 11. Fasteners 12 are provided at both ends of the screw shaft 11. The screw shaft 11 serves as a connecting component between the pressing wheel 3 and the mounting base 1. It not only bears the role of supporting the pressing wheel 3 but also enables the pressing wheel 3 to rotate flexibly around it. The screw shaft 11 is usually made of a metal material with relatively high strength to ensure that it will not easily deform or be damaged when bearing the pressure of the pressing wheel 3 and the frictional force during the rotation process.

[0058] Among them, the setting of the fasteners 12 makes the assembly and disassembly of the pressing wheel 3 and the mounting base 1 more convenient.

[0059] Furthermore, the limiting ring 4 includes a mounting portion 41, an extending portion 42 and a limiting portion 43;

[0060] The mounting portion 41 is sleeved on the screw shaft 11. The mounting portion 41 is arranged between the mounting base 1 and the fasteners 12. While the fasteners 12 fix the screw shaft 11, they also fix and limit the mounting portion 41;

[0061] The extending portion 42 is connected to the mounting portion 41 and the limiting portion 43. The length and angle of the extending portion 42 are designed to correspond to the positional relationship between the mounting base 1 and the pressing wheel 3, so that the limiting portion 43 can be accurately located on the pressing path of the sealing strip, providing effective limiting and guiding for the sealing strip;

[0062] The limiting portion 43 is arranged in a ring shape. The sealing strip passes through the limiting portion 43. The inner diameter of the limiting portion 43 is larger than the outer diameter of the sealing strip. The limiting portion 43 can limit the sealing strip within its ring range, ensuring the positional accuracy of the strip in the left - right direction and preventing the strip from deviating from the position of the installation groove when being extruded by the pressing wheel 3.

[0063] It should be noted that when it is necessary to adjust the position of the limiting ring 4 according to different sealing strip sizes or different operating scenarios, the design of the fasteners 12 makes the adjustment process relatively simple. The operator only needs to loosen the fasteners, adjust the position of the limiting ring, and then tighten the fasteners again. If, when switching to different models of sealing strips, the new strip requires a different limiting height, the position of the limiting ring 4 can be quickly adjusted through the fasteners 12, thereby improving work efficiency.

[0064] In addition, the handle 5 is connected to the mounting base 1 by screw-thread fit. Nuts 13 are fixedly arranged on both sides of the mounting base 1. External threads are provided on the outer wall of the end of the handle 5 connected to the nuts 13. The nuts 13 on both sides of the mounting base 1 provide stable support points for the connection of the handle 5. The nuts 13 and the mounting base 1 are fixed together by welding to ensure that they will not loosen during use. Moreover, through the screw-thread fit between the nuts 13 on both sides and the handle 5, the mounting position of the handle 5 on the mounting base 1 can be adjusted to adapt to the gripping habits and operation requirements of different operators.

[0065] Embodiment 2:

[0066] The second embodiment of the present utility model is described with reference to Embodiment 1. The difference compared with Embodiment 1 is as follows:

[0067] As Figures 6-9 shown, an auxiliary pressing wheel 6 is arranged at the rear side of the pressing wheel 3. The lower end of the auxiliary pressing wheel 6 is flush with the lower end of the pressing wheel 3. The auxiliary pressing wheel 6 is rotatably mounted on the mounting base 1 through a connecting shaft 14. Fixing members 15 are arranged at both ends of the connecting shaft 14. After the pressing wheel 3 performs a preliminary extrusion and embedding operation on the sealing strip, the auxiliary pressing wheel 6 can compact and arrange the embedded part again. This setting can improve the quality and firmness of the embedding of the sealing strip into the installation groove.

[0068] Furthermore, during the operation of the tooling, the pressing wheel 3 and the auxiliary pressing wheel 6 are respectively in contact with the operation surface, forming a multi-point support structure. When the speed of the tooling changes during the pushing process or when there are local resistance changes of the sealing strip, the auxiliary pressing wheel 6 can adapt to these changes in real time. Through the cooperation with the pressing wheel 3, it is ensured that the tooling always maintains balance during the dynamic operation process and avoids shaking.

[0069] Even further, both the pressing wheel 3 and the auxiliary pressing wheel 6 are located on one side of the mounting base 1. When some sealing strips need to be embedded in the sealing groove on the edge of the wall, and the space on the edge of the wall is usually relatively narrow. Arranging the pressing wheel 3 and the auxiliary pressing wheel 6 on the same side can enable the operator to operate the tooling more conveniently in the limited space, and can improve the operation efficiency and sealing quality in complex environments.

[0070] Working process:

[0071] The operator holds the handle 2 and the handle 5 with both hands, picks up the tooling and approaches the wall, so that the side where the pressing wheel 3 and the auxiliary pressing wheel 6 are located is close to the position of the sealing groove on the edge of the wall.

[0072] When the operation starts, the sealing strip enters the working area under the guidance of the limiting ring 4, wherein the sealing strip passes through the limiting portion 43 of the limiting ring 4. Since the pressing wheel 3 is rotatably connected to the mounting seat 1 through the screw shaft 11, and the two ends of the screw shaft 11 are fixed with fasteners 12, the pressing wheel 3 can flexibly rotate on the mounting seat 1. The groove 31 at the circumferential edge where the pressing wheel 3 contacts the sealing strip squeezes and resists the sealing strip, and at the same time, the pressing wheel 3 rolls along the sealing strip to embed the sealing strip into the mounting groove.

[0073] After the pressing wheel 3 starts working, the auxiliary pressing wheel 6 located at the rear side thereof is rotatably mounted on the mounting seat 1 through the connecting shaft 14 and the fixings 15 at both ends to re-compact and sort the sealing strip that has been squeezed by the pressing wheel 3. The lower end of the auxiliary pressing wheel 6 is flush with the lower end of the pressing wheel 3 to ensure the continuity and uniformity of the operation.

[0074] During the entire operation, the operator controls the moving direction and force of the tooling by means of the handle 2 and the handle 5 to ensure that the sealing strip can be accurately and firmly embedded in the sealing groove at the edge of the wall.

[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
