Description

Technical Field

[0001] This utility model belongs to the field of roll material production, and in particular relates to a roll material feeding device. Background Technology

[0002] In existing roll-to-roll production, such as digital printing, roll-to-roll printing media need to be installed on a feeding device during production. However, the width of the rolls that the feeding device can produce is fixed when it leaves the factory. Users cannot use the same feeding device to produce rolls of various specifications, which limits the equipment in production. In other words, the equipment cannot be put into production at its maximum capacity, resulting in a waste of resources. Utility Model Content

[0003] The roll material feeding device provided by this utility model aims to solve the problem of resource waste caused by the inability of the same equipment to be used for the production of roll materials of various specifications in the prior art.

[0004] This utility model is implemented as follows: a roll material feeding device, comprising:

[0005] The support includes two upright plates arranged at relative intervals and a crossbeam connecting the two upright plates;

[0006] A material shaft is detachably rotatably mounted on the two upright plates and located above the crossbeam. The material shaft is used to mount the roll material.

[0007] The support members are in the form of two pieces, which are spaced apart on the crossbeam and located below the material shaft. The support members extend toward the material shaft and support the material shaft. When the roll material is installed on the material shaft, the two support members are located at both ends of the roll material.

[0008] An adapter is configured with each of the support members. The adapter is located between the support member and the material shaft, and the adapter is used to allow the material shaft to rotate relative to the support member.

[0009] Furthermore, the adapter is a bearing, the inner ring of the bearing is sleeved on the material shaft, and the outer ring of the bearing abuts against the support member.

[0010] Furthermore, the support member has a recessed portion at one end supporting the material shaft, and the recessed portion is adapted to the outer ring contour of the bearing.

[0011] Furthermore, the adapter includes a bushing sleeved on the material shaft and two rollers spaced apart at the end of the support member, with a space between the two rollers that is adapted to the outside of the bushing.

[0012] Furthermore, the support member supports one end of the material shaft in a V-shape, and the two rollers are respectively located at both ends of the V-shape.

[0013] Furthermore, the support member includes a support seat disposed on the crossbeam and a support column detachably connected to the support seat.

[0014] Furthermore, a boss is provided above the support base, the support column is mounted on the boss, and the connector passes through the support column and the boss in sequence.

[0015] Furthermore, the portion of the adapter located on the material shaft can move along the axial direction of the material shaft, and the two support members are movably located on the crossbeam.

[0016] Furthermore, the material shaft is an air-expanding shaft. When the expansion element of the air-expanding shaft retracts into the shaft body, the portion of the adapter located on the material shaft can move within the shaft body. When the expansion element of the air-expanding shaft expands out, the expansion element abuts against the portion of the adapter located on the material shaft to fix it to the material shaft.

[0017] Furthermore, a slide rail is provided above the crossbeam, and the two support members are slidably mounted on the slide rail.

[0018] The beneficial effects achieved by this utility model are as follows: by setting two support members, and placing the two support members at the two ends of the roll when it is installed on the material shaft, that is, the two support members abut against the material shaft at both ends of the roll. When the width of the produced roll is small, it can provide local support for the material shaft, which can prevent the roll from being concentrated in the middle of the material shaft, causing the material shaft to bend and deform due to local overweight, thus affecting the stability of the roll being unloaded. The adapter can prevent the support column from interfering with the rotation of the material shaft when supporting the material shaft, thereby affecting the unloading. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] Figures 1-3 This utility model provides a roll material feeding device, including a bracket 1, a material shaft 2, an adapter 3, and support members 4. The bracket 1 includes two relatively spaced upright plates 11 and a crossbeam 12 connecting the two upright plates 11. The material shaft 2 is detachably rotatably mounted on the two upright plates 11 and located above the crossbeam 12. The material shaft 2 is used to mount the roll material. During roll material production, the material shaft 2 can drive the roll material to rotate to achieve roll material feeding. There are two support members 4, spaced apart on the crossbeam 12 and located below the material shaft 2. The support members 4 extend towards and support the material shaft 2. When the roll material is mounted on the material shaft 2, the two support members 4 are located at both ends of the roll material. The adapter 3 is configured one-to-one with the support members 4, and is located between the support members 4 and the material shaft 2. The adapter 3 allows the material shaft 2 to rotate relative to the support members 4.

[0027] By setting two support members 4, and ensuring that the two support members 4 are located at both ends of the roll when the roll is installed on the material shaft 2, that is, the two support members 4 abut against the material shaft 2 located at both ends of the roll, the material shaft 2 can be partially supported when the width of the produced roll is small. This can prevent the roll from being concentrated in the middle of the material shaft 2, which would cause the material shaft 2 to be overweight and bend, affecting the stability of the roll being unloaded. Setting the adapter 3 can prevent the support column 42 from interfering with the rotation of the material shaft when supporting the material shaft 2, thus affecting the unloading.

[0028] The feeding device provided by this utility model can be adapted to the production of at least two types of wide rolls, namely, the original wide rolls of material shaft 2 and rolls with a width smaller than the original rolls, thereby improving the compatibility of the equipment.

[0029] Furthermore, the adapter 3 can be a bearing. The inner ring of the bearing is fitted onto the material shaft 2 so that it rotates with the material shaft 2. The outer ring of the bearing abuts against the support member 4 to maintain relative stillness. In this way, the support member 4 and the reel can maintain relative rotation, avoiding interference between the support member 4 and the reel, which would affect the rotation of the reel and the feeding of the material.

[0030] Furthermore, the support member 4 has a recessed portion at one end supporting the material shaft 2. The recessed portion is adapted to the outer ring contour of the bearing, that is, the recessed portion wraps around part of the outer ring of the bearing, thereby improving the compactness of the structure between the support base 41 and the adapter 3 and improving the stability of the support base 41 supporting the material shaft 2.

[0031] See Figures 2-3 In addition to the bearing structure, the adapter 3 can also adopt other structures. Specifically, the adapter 3 includes a bushing 31 sleeved on the material shaft 2 and two rollers 32 spaced apart at the ends of the support member 4, with a space between the two rollers 32 that fits the outside of the bushing 31. This structure also allows rolling friction to occur between the material shaft 2 and the support member 4, thereby preventing the support member 4 from interfering with the rotation of the material shaft 2 while supporting it.

[0032] Furthermore, the support member 4 supports one end of the material shaft 2 in a V-shape, with two rollers 32 respectively located at both ends of the V-shape. In this way, the bushing 31 can abut against the V-shaped structure of the support member 4, making the structure of the support member 4 and the bushing 31 more compact and improving the stability of the support base 41 in supporting the material shaft 2.

[0033] See Figure 3 Furthermore, the support member 4 includes a support seat 41 disposed on the crossbeam 12 and a support column 42 detachably connected to the support seat 41. Thus, when the support member 4 is not required to support the material shaft 2, for example when the current shaft needs to be installed with a roll of material of a size that is compatible with the length of the shaft, the support member 4 is not required, and the support member 4 can be removed to avoid interfering with the installation of the roll of material.

[0034] See Figure 4 Specifically, a boss 411 is provided above the support base 41, and the support column 42 is covered on the boss 411. That is, the support column 42 can be provided with a hollow structure, or a hollow structure can be provided at the end connected to the support base 41. The connector 5 passes through the support column 42 and the boss 411 in sequence. In this way, the support column 42 can be removed from the support base 41 by removing the connector 5.

[0035] Furthermore, the portion of the adapter 3 located on the material shaft 2 can move along the axial direction of the material shaft 2. That is, the bushing 31 or bearing in the above embodiment can move along the axial direction of the material shaft 2, and the two support members 4 are movably mounted on the crossbeam 12. In this way, the positions of the support members 4 and the adapter 3 on the axial direction of the material shaft 2 can be adjusted according to different roll widths, thereby accommodating the production of rolls of various specifications. For example, assuming that the current material shaft 2 is adapted to the production of 2500mm rolls, by moving the portions of the support members 2 and the adapter 3 located on the material shaft 2, i.e., the bearing or bushing 31, the material shaft can be used to produce rolls smaller than 2500mm, such as 2000mm, 1500mm, 1000mm, etc. The positions of the support members 4 and the adapter 3 can be adjusted according to the actual roll width, which is not limited here.

[0036] Specifically, the material shaft 2 is an air shaft. When the expansion element of the air shaft retracts into the shaft body, the part of the adapter 3 located on the material shaft 2 (i.e., the bearing or bushing 31 in the above embodiment) can move on the shaft body. When the expansion element of the air shaft expands out, the part of the expansion element adapter 3 located on the material shaft 2 abuts against it to fix it on the material shaft 2.

[0037] See Figure 4 Furthermore, a slide rail 6 is provided above the crossbeam 12, and two support members 4 are slidably mounted on the slide rail 6. The slide rail 6 guides the movement of the support members 4 on the crossbeam 12. Specifically, the bottom of the support member 4 is provided with a slider 7 that cooperates with the slide rail 6. One slide rail 6 can be provided, which extends along the length of the crossbeam 12. Alternatively, two slide rails 6 can be provided, located at both ends of the crossbeam 12. The space in the middle, used for installing the roll material, can be left without slide rails 6 to reduce material costs.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
