[0016] 1. This application utilizes a support shaft that axially penetrates the film roll, effectively supporting the paper tube within the film roll's cavity and preventing deformation. Furthermore, the suspension of the film roll via a support plate avoids deformation at points of prolonged contact with the ground. Simultaneously, the design of the guide ramp on the support plate facilitates the movement of the support shaft to the top of the support plate. Moreover, the coaxially mounted rotating part at the end of the support shaft prevents frictional damage caused by relative movement between the support shaft and the hand when directly gripping it. Especially when the support shaft contacts the guide ramp, the worker's hand can apply force to the support shaft through the rotating part's rotational engagement, while also allowing the support shaft to roll upwards along the guide ramp, effectively reducing friction as it moves to the top of the support plate. This enables convenient manual suspension of the film roll without the need for forklift equipment.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of membrane roll processing technology, specifically a membrane roll support component. Background Technology
[0002] To ensure that the production workshop has sufficient film roll reserves, a certain number of film rolls are often stored in the production workshop to avoid production shutdowns caused by the inability to replenish film roll raw materials in time.
[0003] Most existing membrane roll structures, such as those described in Chinese Patent Publication No. CN109230887A entitled "An Environmentally Friendly PE Roll Film," use a paper tube as an inner liner, with the film wound around the outer circumference of the paper tube to form a membrane roll. Currently, small-tonnage membrane rolls are mostly stored flat on the workshop floor before unwinding and slitting. While this storage method ensures convenience for short-term storage, prolonged storage without orders can lead to pressure deformation at the contact point between the membrane roll and the ground. This deformation causes fluctuations in the tension of the membrane material during unwinding, resulting in material feeding jitter and unstable speed. Furthermore, the flat laying process also exerts pressure on the paper tube inside the membrane roll, causing deformation and making it difficult to insert the paper tube into the outer circumference of the unwinding roller. Therefore, this issue urgently needs to be addressed. Utility Model Content
[0004] In order to avoid and overcome the technical problems existing in the prior art, this utility model provides a film roll support assembly, which can effectively support the inner cavity of the paper tube of the film roll, and at the same time, can easily separate the film roll from the ground, preventing the part of the film roll in contact with the ground from being deformed by pressure during long-term storage.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A membrane roll support assembly includes a support shaft that can be axially inserted through the inner cavity of the membrane roll and two support plates arranged parallel to each other and vertically. The two support plates are spaced apart and their top sides respectively support the shaft at one end of the support shaft, so that the membrane roll is suspended in the air. The same side of the two support plates is inclined and together forms a guide ramp that allows the support shaft to move to the top side of the support plate. Both ends of the support shaft are coaxially rotated and fitted with a rotating part for gripping.
[0007] As a further embodiment of this utility model: an end sleeve is coaxially and detachably fixed to the outer periphery of the end of the supporting shaft, the outer periphery of the end sleeve is fixedly connected to the inner ring of the bearing, and a handle is fixed on the outer ring of the bearing. The outer ring of the bearing and the handle together constitute the rotating part.
[0008] As a further improvement of this utility model, the end sleeve and the supporting shaft are connected by a threaded connection or a flange connection.
[0009] As a further embodiment of this utility model: the top side of the support plate has at least two vertical insertion holes arranged at intervals along its length direction, the interval between adjacent vertical insertion holes is used to accommodate the support shaft, and when the support shaft rolls between adjacent vertical insertion holes, the horizontal radial movement of the support shaft is locked by a positioning pin axially inserted into the inner cavity of the vertical insertion hole.
[0010] As a further improvement of this utility model: the top side of the support plate has a placement space for suspending at least two membrane rolls, and the vertical insertion holes are arranged at least four at intervals along the length direction of the top side of the support plate.
[0011] As a further improvement of this utility model, the surface of the support plate is in the shape of an isosceles trapezoid.
[0012] As a further improvement of this utility model, the inclination angle of the material guiding slope is between 10° and 30°.
[0013] As a further improvement of this utility model, the connection between the top side and the inclined side of the support plate is provided with a rounded corner.
[0014] As a further improvement of this utility model, a connecting base plate is fixed between the lower parts of the two support plates to connect them.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. This application utilizes a support shaft that axially penetrates the film roll, effectively supporting the paper tube within the film roll's cavity and preventing deformation. Furthermore, the suspension of the film roll via a support plate avoids deformation at points of prolonged contact with the ground. Simultaneously, the design of the guide ramp on the support plate facilitates the movement of the support shaft to the top of the support plate. Moreover, the coaxially mounted rotating part at the end of the support shaft prevents frictional damage caused by relative movement between the support shaft and the hand when directly gripping it. Especially when the support shaft contacts the guide ramp, the worker's hand can apply force to the support shaft through the rotating part's rotational engagement, while also allowing the support shaft to roll upwards along the guide ramp, effectively reducing friction as it moves to the top of the support plate. This enables convenient manual suspension of the film roll without the need for forklift equipment.
[0017] 2. The detachable end sleeve design allows for quick assembly and disassembly of the rotating section by simultaneously replacing the end sleeve and bearing after bearing damage. Furthermore, this detachable design of the rotating section allows the outer diameter of the bearing ring constituting the rotating section to be significantly larger than the diameter of the support shaft. Additionally, the handle on the bearing outer ring facilitates gripping the enlarged diameter rotating section, increasing the lever arm for driving the support shaft and thus reducing effort required to move it. When installing the support shaft to the membrane roll, simply remove the end sleeve from one end of the support shaft, insert that end into the membrane roll, and then reinstall the end sleeve. The operation is simple and does not significantly increase the difficulty of supporting shaft installation.
[0018] 3. The top side of the support plate has at least two vertical insertion holes spaced apart along its length, with the gap between adjacent vertical insertion holes used to accommodate the support shaft. In use, when the support shaft rolls between adjacent vertical insertion holes, a positioning pin axially inserts into the inner cavity of the vertical insertion hole, thereby locking the horizontal radial movement of the support shaft through the positioning pin. This not only facilitates operation but also effectively prevents the film roll from accidentally falling off during storage, ensuring storage safety.
[0019] 4. The inclination angle of the guide ramp is between 10° and 30°, which reduces the difficulty for the support shaft to move to the top side of the support plate through the guide ramp, and also reduces the potential energy of the support shaft sliding down from the top side of the support plate through the guide ramp. This ensures that the loading and unloading process of the film roll maintains a stable and controllable motion state, improving operational safety and efficiency.
[0020] 5. A connecting base plate is fixed between the lower parts of the two support plates, so that the two support plates form a whole. The support plates do not need to be fixed to the floor in the workshop, which makes it easy to adjust the placement of the support plates later. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] For ease of understanding, the specific structure and working method of this utility model are further described below with reference to the accompanying drawings:
[0027] The specific structure of this utility model is as follows: Figure 1-3 As shown, its main structure includes a support shaft 20 that can be axially inserted through the inner cavity of the membrane roll a and two support plates 10 that are parallel to each other and arranged vertically.
[0028] like Figure 1 As shown, in actual arrangement, the gap between the two support plates 10 is set to be greater than the length of the membrane roll a. This allows the top sides of the two support plates 10 to support the shaft of one end of the support shaft 20, so that the membrane roll a is suspended in the air. The support shaft 20 replaces the rollers of the membrane roll a during winding and unwinding to suspend the membrane roll a in the air, avoiding the deformation of the part of the membrane roll a in contact with the ground for a long time.
[0029] Furthermore, such as Figure 1 As shown, both ends of the support shaft 20 are coaxially rotatable with rotating parts for gripping. Furthermore, as... Figure 2 As shown, the two support plates 10 are both arranged at an angle on the same side and together form a guide ramp 11 that allows the support shaft 20 to move to the top side of the support plate 10. Specifically, the movement of the support shaft 20 is a combination of sliding and rolling. When suspending the membrane roll a, two workers only need to hold the rotating parts at both ends of the support shaft 20 and roll the membrane roll a to the inclined starting point of the guide ramp 11. Then, using the inclined guide ramp 11, the support shaft 20 can move to the top side of the support plate 10. The rotating part avoids frictional damage caused by the relative movement between the support shaft 20 and the palm when directly holding the support shaft 20; especially when the support shaft 20 comes into contact with the guide slope 11, the rotation of the support shaft 20 by the operator's palm facilitates the application of force to the support shaft 20 by the palm, and at the same time, it also allows the support shaft 20 to roll as it slides up the guide slope 11, effectively reducing the friction when the support shaft 20 moves to the top side of the support plate 10, making it easier for the film roll a to be moved to the top side of the support plate 10 manually without the need for forklift equipment to coordinate the work.
[0030] Based on the above, such as Figure 1 and Figure 2As shown, an end sleeve 21 is detachably fixed to the outer periphery of the end of the support shaft 20. The outer periphery of the end sleeve 21 is fixedly connected to the inner ring of the bearing 22. A handle 23 is fixed on the outer ring of the bearing 22. The outer ring of the bearing 22 and the handle 23 together constitute the rotating part.
[0031] The detachable design of the end sleeve 21 allows for quick assembly and disassembly of the rotating part by simultaneously replacing both the end sleeve 21 and the bearing 22 after the bearing 22 is damaged. Furthermore, this detachable design of the rotating part allows the outer diameter of the bearing 22, which constitutes the rotating part, to be much larger than the diameter of the support shaft 20. Additionally, the handle 23 on the outer ring of the bearing 22 facilitates gripping the enlarged diameter rotating part, increasing the lever arm required to drive the support shaft 20 and thus requiring less effort to move it. When installing the support shaft 20 onto the membrane roll a, it is only necessary to remove the end sleeve 21 from one end of the support shaft 20, insert that end into the membrane roll a, and then reinstall the end sleeve 21. The operation is simple and does not significantly increase the difficulty of installing the support shaft 20.
[0032] Specifically, the end sleeve 21 and the support shaft 20 can be connected by thread or flange, or they can be fixed by a pin as in the existing technology, which can achieve stable fixation between the end sleeve 21 and the support shaft 20 and quick assembly.
[0033] Of course, in actual implementation, the rotating part can also be a rotating column that is coaxially rotated at the end of the support shaft 20 and has a diameter less than or equal to that of the support shaft 20. This embodiment increases the ease of assembly of the support shaft 20, but will increase the friction when driving the support shaft 20 to move.
[0034] Based on the above, such as Figure 3 As shown, to ensure the stable and fixed suspension of the support shaft 20 on the top side of the support plate 10, the top side of the support plate 10 has at least two vertical insertion holes 13 spaced apart along its length. The gap between adjacent vertical insertion holes 13 is used to accommodate the support shaft 20. In use, when the support shaft 20 rolls between adjacent vertical insertion holes 13, the positioning pin 30 is axially inserted into the inner cavity of the vertical insertion hole 13, thereby locking the horizontal radial movement of the support shaft 20 through the positioning pin 30. This not only makes operation convenient but also effectively prevents the film roll a from accidentally falling off during storage, ensuring storage safety.
[0035] Furthermore, such as Figure 2 As shown, the top side of the support plate 10 has a placement space for suspending at least two membrane rolls a, such as... Figure 3 As shown, the vertical insertion holes 13 are arranged at least four at intervals along the length of the top side of the support plate 10, so that the support plate 10 can accommodate the suspended installation of multiple membrane rolls a.
[0036] In addition, such as Figure 2 As shown, preferably, the surface of the support plate 10 is an isosceles trapezoidal structure, so that both sides of the support plate 10 can be used to support the loading or unloading of the shaft 20. Where space permits, this reduces the limitations of loading and unloading on the top side of the support plate 10.
[0037] Preferably, the inclination angle of the guide ramp 11 is between 10° and 30°, which reduces the difficulty for the support shaft 20 to move to the top side of the support plate 10 through the guide ramp 11, and also reduces the potential energy of the support shaft 20 sliding down from the top side of the support plate 10 through the guide ramp 11, so that the loading and unloading process of the film roll a maintains a stable and controllable motion state, and improves operational safety and efficiency.
[0038] Preferred, such as Figure 2 As shown, the connection between the top side of the support plate 10 and the inclined side is provided with a rounded corner, which reduces the wear of the support shaft 20 between the guide slope 11 and the top side of the support plate 10.
[0039] Based on the above, such as Figure 1 As shown, a connecting base plate 12 is fixed between the lower parts of the two support plates 10, so that the two support plates 10 form a whole. The support plates 10 do not need to be fixed to the ground in the workshop, which makes it easy to adjust the placement of the support plates 10 later.
[0040] Of course, those skilled in the art will recognize that this invention is not limited to the details of the exemplary embodiments described above, but also includes the same or similar structures that can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
