However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0023] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0024] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0025] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0026] In the present application, unless otherwise clearly specified and limited, a first feature being “above” or “below” a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being “above”, “above”, and “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being “below”, “below”, and “below” a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0027] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0028] Reference Figure 1, is a belt pressing device in the related art, which includes an axis and a belt pressing roller 22 rotatably connected to the axis through a bearing, the axis is connected to the upper fixed seat 13 through baffles at both ends, a retaining ring is abutted between the belt pressing roller 22 and the baffle, one side of the retaining ring is pressed against the baffle, and the other side of the retaining ring is pressed against the bearing, and the fixed seat 13 is welded to the corresponding equipment for fixing. With this structure, on the one hand, since the fixed seat 13 is welded to the equipment, it is difficult to adjust it later; on the other hand, due to the inevitable errors during assembly, the retaining ring is easy to interfere with the bearing or crush the bearing, making the belt pressing roller 22 inflexible or even unable to rotate.

[0029] Reference Figure 2 and Figure 3 To this end, the present application provides a belt pressing device for winding, including a support component 1, a belt pressing wheel component 2 arranged on the support component 1, and a connecting component 3. The belt pressing wheel component 2 is used to stably roll the material, and the connecting component 3 is used to conveniently connect the pressing device to an external device.

[0030] Specifically, the support assembly 1 includes a fixing plate 11, which is arranged horizontally. The fixing plate 11 has side baffles 12 detachably connected to both sides thereof. In this embodiment, the side baffles 12 are detachably connected to the fixing plate 11 by threaded connection, and the side baffles 12 are used to cooperate with the installation of the belt pressure roller assembly 2.

[0031] The belt pressing roller assembly 2 includes a belt pressing shaft core 21 arranged on the supporting assembly 1, the belt pressing shaft core 21 is arranged horizontally, and both ends of the belt pressing shaft core 21 are respectively installed on the side baffle 12. One end of the belt pressing shaft core 21 is installed with the side baffle 12 on one side through a threaded connection, and the other end of the belt pressing shaft core 21 is installed with the side baffle 12 on the other side through a threaded connection, thereby realizing a detachable connection.

[0032] Reference Figure 3 and Figure 4In order to avoid interference, a positioning shoulder 211 is provided on one side of the belt pressing shaft core 21, and a first positioning retaining ring 23 is provided at the positioning shoulder 211. The first positioning retaining ring 23 and the side baffle 12 on the corresponding side have a certain distance to have a gap, and the first positioning retaining ring 23 can be a shaft retaining ring; accordingly, a second positioning retaining ring 24 is sleeved on the other side of the belt pressing shaft core 21, and the second positioning retaining ring 24 and the side baffle 12 on the corresponding side also have a certain distance to have a gap, and the second positioning retaining ring 24 can be a bearing retaining ring. A belt pressing roller 22 rotatably connected to the belt pressing shaft core 21 is provided between the first positioning retaining ring 23 and the second positioning retaining ring 24. There is a belt hold bearing 25 between the belt hold roller 22 and the belt hold shaft core 21. There are two belt hold bearings 25. The two belt hold bearings 25 are respectively located at the two ends of the belt hold roller 22 and abut against the corresponding positioning retaining rings. Since there is a gap between the first positioning retaining ring 23 and the second positioning retaining ring 24 and the side baffle 12, the belt hold bearings 25 can be prevented from interfering with or being crushed due to assembly errors, thereby ensuring the normal operation of the belt hold roller 22 after assembly; at the same time, the first positioning retaining ring 23 can be accurately and quickly installed using the positioning shaft shoulder 211 during assembly, thereby improving assembly efficiency and product yield.

[0033] In order to cooperate with the installation of the connection component 3, a fixing seat 13 is installed on the side of the fixing plate 11 away from the side baffle 12. The fixing seat 13 can be installed on the fixing plate 11 by threaded connection. The connection component 3 includes a connecting rod 31 installed on the fixing seat 13, a locking member 32 for limiting the connecting rod 31, and a rotation limiting block 33. The connecting rod 31 is provided with a plurality of connecting holes 311 for connecting with other devices along its length direction. The connecting hole 311 can be a pin hole, a countersunk through hole, or a mixture of a pin hole and a countersunk through hole, as long as it can be installed in cooperation with the external device. By setting the connecting rod 31, the press-fitting device can be conveniently installed on the external device for cooperation, can be conveniently adjusted during use, and can be disassembled for replacement or repair after use.

[0034] Reference Figure 2 and Figure 5 In order to adapt to the installation of the connecting rod 31, the fixing seat 13 is provided with a mounting hole. One end of the connecting rod 31 in the length direction has a connecting end with a smaller radius. The size of the connecting end is adapted to the size of the mounting hole. After the connecting end is inserted into the mounting hole, it is detachably connected with the locking member 32. The connecting end and the locking member 32 can be specifically threaded. A connecting bearing 312 is provided between the connecting rod 31 and the mounting hole. By providing the connecting end and the locking member 32, the connecting rod 31 can be conveniently and quickly positioned and installed on the fixing seat 13 and limited in the horizontal direction.

[0035] The rotation-limiting block 33 is used to limit the rotation of the connecting rod 31. In this embodiment, the rotation-limiting block 33 is in a "U" shape. The rotation-limiting block 33 is arranged along the edge of one side of the fixing seat 13. The middle part of the rotation-limiting block 33 has a rotation-limiting portion 332, and the two sides of the rotation-limiting block 33 have connecting portions 331. After being installed in place, the rotation-limiting portion 332 will be located below the connecting rod 31 and threadedly connected to the connecting rod 31 to achieve a detachable connection, while the connecting portion 331 is limited to the fixing plate 11. The connecting portion 331 is penetrated by a stop bolt 34, which faces the fixing plate 11 and is pressed against the fixing plate 11. By setting the rotation-limiting block 33, tightening the stop bolt 34 can limit the connecting rod 31, thereby preventing the connecting rod 31 from rotating during use and affecting the rolling process.

[0036] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, 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, they should be considered to be within the scope of this specification.

[0037] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
