Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hydraulic hose production, in particular to a middle rubber sheet connecting device used for producing hydraulic hoses. Background Art
[0002] In a multi-layer steel wire reinforced hydraulic hose, there are multiple layers of steel wire braiding. In order to fix the multiple layers of steel wire and prevent the multiple layers of steel wire from wearing each other, a middle rubber layer is provided between the steel wire layers to fix the position of the steel wire and prevent the adjacent steel wire layers from contacting each other. The thickness of the middle rubber layer is usually less than 1mm. The raw material of the middle rubber layer is middle rubber sheet, which is usually supplied in the form of a roll of middle rubber roll. The width of the middle rubber roll is fixed. During the production process of the hydraulic hose, the middle rubber sheet is wrapped or wound between the two layers of steel wire during the braiding or winding process of the hose steel wire. The length of the middle rubber roll is usually hundreds of meters, and each batch of hoses is produced for thousands of meters, so multiple middle rubber rolls are required for each batch of hoses.
[0003] The newly put in medium film roll and the medium film roll that is about to be used up need to be connected end to end and put into the hydraulic hose production line in a continuous state. The current connection method is manual hammering. The specific operation steps are: overlap the end and the end by about 2cm, place them on a plane, and use an iron tool to knock on the overlapping position several times so that the upper and lower layers of rubber at the knocked position adhere together to achieve the state of end-to-end connection. There are many problems with current manual hammering, such as: the process is cumbersome, and all overlapping positions need to be knocked at least 20 times to form a relatively stable connection; the knocking positions are uneven, the connection quality is unstable, and the positions that are missed are prone to breakage during use; the knocking force is uneven, the resulting connection surface is irregularly distributed, and the medium film on the connection surface is prone to being too thick or too thin.

DETAILED DESCRIPTION
[0030] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0031] Embodiment 1:
[0032] A middle rubber sheet connecting device for producing hydraulic hoses, such as Figure 1 As shown, it includes: a base plate 1, a cover plate 2, a pressing wheel 3 and a handle 4;
[0033] like Figure 3 As shown, a first long hole 5 is provided on the cover plate 2, and in the length direction of one end of the first long hole 5, the edges of the bottom plate 1 and the cover plate 2 are rotatably connected;
[0034] like Figure 2 As shown, the pressing wheel 3 includes a rolling portion 31 and connecting portions at both ends of the rolling portion 31. The rolling portion 31 is cylindrical, and the connecting portion includes a rotating shaft 32 colinear with the central axis of the rolling portion 31. The rolling portion 31 can roll along the first long hole 5, and a plurality of protrusion structures 33 extend from the surface of the rolling portion 31 along the diameter direction, such as Figure 3 As shown, the top end of the protruding structure 33 is located between the bottom plate 1 and the cover plate 2;
[0035] The cover plate 2 is provided with a roller track, which is parallel to the length direction of the first long hole 5 , and the rotating shaft 32 can roll on the roller track.
[0036] like Figure 1 As shown, the handle 4 is rotatably connected to the rotation shaft 32 .
[0037] Through the above arrangement, when the middle film is placed between the bottom plate 1 and the cover plate 2, the pressure wheel 3 moves on the roller track, and the raised structure 33 can apply pressure to the middle film, forming a plurality of pressure points with the same distribution as the raised structure 33, thereby achieving effective adhesion of the upper and lower layers of the middle film and replacing the hammering operation.
[0038] like Figure 2 As shown, the cover plate 2 is connected to two vertical plates 21 on the surface away from the bottom plate 1. The two vertical plates 21 are perpendicular to the surface of the cover plate 2, and as shown in FIG. Figure 3 As shown, the two vertical plates 21 are respectively located on both sides of the first long hole 5, and a second long hole 22 is provided on the vertical plate 21, and the length direction of the second long hole 22 is parallel to the length direction of the first long hole 5; the second long hole 22 acts as a roller track, providing a track for the movement of the rotating shaft 32, and connecting the cover plate 2 and the pressure wheel 3 as a movable device as a whole to avoid the pressure wheel 3 from being lost.
[0039] like Figure 3 As shown, the rotating shaft 32 of the pressing wheel 3 passes through the second long hole 22, the pressing wheel 3 is located between the two vertical plates 21, and the connection position between the rotating shaft 32 and the handle 4 is located on the outside of the two vertical plates 21; the second long hole 22 limits the up and down movement range of the pressing wheel 3, which is convenient for the operator to operate.
[0040] like Figure 3As shown, multiple protrusion structures 33 have the same shape, and the protrusion structures 33 are hemispherical. Multiple protrusion structures 33 are arranged on the surface of the rolling part 31, and are arranged in a straight line in the width direction of the rolling part 31. The rolling part 31 is provided with multiple rows of protrusion structures 33 with the same spacing, so that multiple pressure points with uniform distribution positions are formed on the rolled middle film, which effectively prevents the situation where the middle film is not firmly connected.
[0041] The width of the rolling portion 31 is smaller than the width of the first long hole 5 , so that the rolling portion 31 can effectively press the middle film under the cover plate 2 .
[0042] like Figure 2 As shown, the handle 4 includes a plurality of support rods 41 and a grip portion 42. The support rods 41 are rotatably connected to the two rotating shafts 32 of the pressure wheel 3 respectively. The grip portion 42 connects the ends of the support rods 41 on both sides away from the rotating shaft 32, so that the operator can realize the rolling of the pressure wheel 3 in the first long hole 5 by pushing out the support rods 41.
[0043] like Figure 3 As shown, the width of the second long hole 22 is greater than the outer diameter of the rotating shaft 32 , so that the operator can adjust the squeezing force of the pressing wheel 3 on the film according to the height of the rotating shaft 32 in the second long hole 22 .
[0044] The edges of the bottom plate 1 and the cover plate 2 are connected by hinges, so that the cover plate 2 can be opened to facilitate the placement of the film.
[0045] When the bottom plate 1 and the cover plate 2 are parallel to each other, the distance between the bottom plate 1 and the cover plate 2 can be adjusted to accommodate middle films of different thicknesses, so that when middle films of different thicknesses are placed, the bottom plate 1 and the cover plate 2 are parallel to each other, effectively ensuring the adhesion quality of the middle films.
[0046] like Figure 4 As shown, the upper surface of the base plate 1 and the lower surface of the cover plate 2 are respectively provided with limiting protrusions 6, and the limiting protrusions 6 are arranged along the length direction of the first long hole 5. The limiting protrusions 6 on the upper surface of the base plate 1 are used to position the edge of the film 71 in the lower layer, and the limiting protrusions 6 on the lower surface of the cover plate 2 are used to position the edge of the film 72 in the upper layer. This positioning device can ensure that the overlap range of the beginning and end of the films in the upper and lower layers is about 2 cm, thereby avoiding material waste.
[0047] When the middle rubber sheet is connected by the middle rubber sheet connecting device for producing hydraulic hoses of this embodiment, the operation process includes:
[0048] Place the two middle films to be connected between the cover plate 2 and the bottom plate 1 so that they overlap under the pressure wheel 3, and control the width of the overlapped part to be about 2 cm by the limiting protrusion 6. After closing the cover plate 2 and the bottom plate 1, hold the handle 4 to press the pressure wheel 3, and make the rolling part 31 of the pressure wheel 3 roll back and forth in the first long hole 5, so that the protrusion structure 33 squeezes the two layers of the middle films below, so that the middle films adhere together through pressure, thereby forming a stable connection. The labor intensity of the operation of the operator holding the handle 4 to press the pressure wheel 3 is significantly lower than the operation of hammering with an iron tool, and there is no need to manually control the position of the pressing point, which can improve the stability of the connection quality of the middle films and prevent the situation where the middle films are not firmly connected; and it can also improve the connection efficiency, which can be increased by more than 50%.
[0049] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
