DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model is described clearly and completely. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Embodiment 1

[0032] In order to solve the technical problems in the background technology, a rolling and flattening device for medical dialysis paper is provided as follows:

[0033] Combination Figure 1-Figure 5As shown, the utility model provides a winding and flattening device for medical dialysis paper, comprising a base plate 1, a fixed plate 11 is fixedly installed on the top of the base plate 1, a stop block 12 is rotatably installed on the fixed plate 11, a motor 13 for driving the stop block 12 to rotate is fixedly installed on the fixed plate 11, a movable plate 14 is slidably installed on the top of the base plate 1 along the direction of the fixed plate 11, a stop block 2 15 is rotatably installed on the movable plate 14, the stop block 2 15 and the axis direction of the stop block 12 are located on the same straight line, and an electric push rod 16 for driving the movable plate 14 to slide is fixedly installed on the base plate 1; a vertical shell 2 is fixedly installed on the top of the movable plate 14, and a vertical sliding connection is installed in the shell 2. There is a connecting block 24, a connecting rod 21 that movably passes through the top of the shell 2 is fixed on the top of the connecting block 24, a horizontal pressing plate 22 is fixedly installed on the top of the connecting rod 21, a spring 23 that is sleeved on the outside of the connecting rod 21 is installed in the shell 2 and between the opposite sides of the shell 2 and the connecting block 24, and a limiting member 3 that acts on the connecting block 24 is installed on the shell 2, which is used to fix or cancel the fixation between the shell 2 and the connecting block 24; a flattening mechanism 4 is installed on the top of the bottom plate 1 and on one side of the fixed plate 11 and the movable plate 14, which is used to flatten the rolled dialysis paper, and a cutting mechanism 5 for cutting the dialysis paper is installed on the side of the pressing plate 22 close to the flattening mechanism 4.

[0034] When in use, when rolling up the dialysis paper, a force is applied to the pressure plate 22 to make it slide upward along the connecting rod 21, and the connecting block 24 is limited by the limit piece 3. At this time, the spring 23 is deformed by the force, and the winding shaft for winding up the dialysis paper is placed between the opposite sides of the block 12 and the block 2 15, and the winding shaft is in contact with the block 12. The electric push rod 16 is controlled to make the movable plate 14 slide on the bottom plate 1 toward the fixed plate 11, so that the block 2 15 is in contact with the end of the winding shaft, and the winding shaft can be fixed by the block 12 and the block 2 15, and the end of the dialysis paper is wound on the winding shaft, and the motor 13 is controlled to make the block 12 rotate on the fixed plate 11, thereby driving the winding shaft to rotate to wind and rewind the dialysis paper. During this period, the rolled dialysis paper is flattened by the flattening mechanism 4, so that the dialysis paper can be rolled up flatly. On the reel, after the dialysis paper is rolled up, the limit of the connection block 24 by the limiter 3 is cancelled, and the spring 23 returns to its natural state, so that the connection block 24 slides downward in the shell 2, driving the pressing plate 22 to move downward, so that the top of the rolled dialysis paper can be pressed by the pressing plate 22. By setting a cutting mechanism 5, the cutting mechanism 5 is installed on the side of the pressing plate 22 close to the flattening mechanism 4. After the dialysis paper is rolled up and the top of the rolled dialysis paper is pressed by the pressing plate 22, the dialysis paper that has not been rolled up on one side of the pressing plate 22 can be cut by the cutting mechanism 5, and the staff does not need to manually cut the dialysis paper with a cutting knife, thereby reducing the workload of the staff, and effectively avoiding the unevenness of the cut part of the dialysis paper when the staff manually cuts the dialysis paper with a cutting knife, thereby improving the aesthetics.

[0035] Embodiment 2

[0036] like Figure 1-Figure 5 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0037] In this embodiment, the limiter 3 includes a bracket 31 fixedly mounted on one side of the shell 2, a pull rod 32 is movably penetrated in the horizontal direction along the shell 2 on the bracket 31, a clamping block 33 movably penetrates the shell 2 is fixed on the side of the pull rod 32 close to the shell 2, and a clamping hole 241 is opened on the side of the connecting block 24 close to the clamping block 33. One end of the clamping block 33 extending into the shell 2 can be inserted into the clamping hole 241 and clamped with the connecting block 24. When in use, the pull rod 32 is pulled to make the clamping block 24 open. The block 33 slides toward the outside of the shell 2, so that the end of the block 33 is displaced to the outside of the hole 241, and the positioning of the connecting block 24 can be cancelled. Conversely, a force is applied to the pressure plate 22 to displace it upward, so that the hole 241 and the block 33 are located on the same horizontal plane, and the pull rod 32 is pushed to slide into the shell 2, so that the block 33 can be inserted into the hole 241, so that the block 33 and the connecting block 24 are engaged, and the position of the connecting block 24 can be fixed, which is easy to operate.

[0038] In this embodiment, the flattening mechanism 4 includes a support plate 41 symmetrically fixedly mounted on one side of the fixed plate 11 and the movable plate 14, and two flattening rollers 42 are rotatably mounted on the support plate 41. The two flattening rollers 42 are located in the same vertical direction, and there is a gap between the two flattening rollers 42. When in use, when the dialysis paper is rolled up, the dialysis paper passes between the two flattening rollers 42, and then is wound around the outside of the winding shaft clamped and positioned by the stop block 12 and the stop block 2 15. The motor 13 is operated to rotate the winding shaft. During the process of rolling up the dialysis paper, the dialysis paper can be flattened by the two flattening rollers 42.

[0039] In this embodiment, the cutting mechanism 5 includes a sliding block 51 which is slidably mounted on the side of the pressing plate 22 close to the flattening roller 42 along the direction of the fixed plate 11 and in a horizontal direction. A knife seat 52 is detachably fixedly mounted on the sliding block 51. A blade 53 is fixedly mounted at the bottom of the knife seat 52. An electromagnetic slider 54 connected to the knife seat 52 is fixedly mounted on the pressing plate 22. When in use, after the rolled-up dialysis paper is pressed by the pressing plate 22, the electromagnetic slider 54 is controlled to work, so that the sliding block 51 slides on the pressing plate 22 toward the fixed plate 11, thereby driving the knife seat 52 and the blade 53 to move. When the blade 53 contacts the dialysis paper during displacement, the dialysis paper can be cut, thereby ensuring that the cut part of the dialysis paper is flat and improving the aesthetics.

[0040] Embodiment 3

[0041] like Figure 1-Figure 5 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0042] In this embodiment, a slot 511 is provided on the side of the sliding block 51 away from the pressure plate 22, and the knife seat 52 is inserted into the slot 511 and fits with the cross-section of the sliding block 51. A fixing member 6 acting on the knife seat 52 is installed in the slot 511, which is used to fix or cancel the fixation between the knife seat 52 and the sliding block 51. Through the design of the slot 511 and the fixing member 6, when the blade 53 needs to be replaced, the fixing of the knife seat 52 and the sliding block 51 by the fixing member 6 is canceled, and the knife seat 52 can be disassembled, thereby disassembling and replacing the knife seat 52 and the blade 53. After the blade 53 is replaced, the new knife seat 52 is inserted into the slot 511, and the knife seat 52 and the sliding block 51 can be fixed by the fixing member 6, which is simple to operate.

[0043] In this embodiment, the fixing member 6 includes: a fixing clamping rod 61, which is hinged on the inner wall of the slot 511 on one side near the pressure plate 22, and a clamping hole 521 is opened on the knife seat 52. When the knife seat 52 is inserted into the slot 511, the fixing clamping rod 61 can pass through the clamping hole 521 and be clamped with the knife seat 52. When in use, a force is applied to the fixing clamping rod 61 to make it rotate in the slot 511 so that the fixing clamping rod 61 can pass through the clamping hole 521. At this time, a force can be applied to the knife seat 52 to pull the knife seat 52 out of the slot 511, thereby achieving the effect of canceling the positioning between the knife seat 52 and the sliding block 51. Conversely, the knife seat 52 is inserted into the slot 511, and the fixing clamping rod 61 is rotated so that its free end is located on the outside of the clamping hole 521, so that the knife seat 52 and the sliding block 51 can be positioned, and the operation is simple.

[0044] In this embodiment, one end of the pressing plate 22 away from the fixed plate 11 extends to the outside of the movable plate 14 and is fixedly installed with a grip rod 221, which is convenient for applying a force to the pressing plate 22 to make it move upward along the connecting rod 21, and the sliding block 51 can slide along the pressing plate 22 to the side of the movable plate 14 away from the fixed plate 11. By setting the sliding block 51, it can slide along the pressing plate 22 to the side of the movable plate 14 away from the fixed plate 11. When the dialysis paper is rolled up using the present device, the sliding block 51 can be slid to the side of the movable plate 14 away from the fixed plate 11 by the electromagnetic slider 54, thereby effectively avoiding the contact between the dialysis paper and the blade 53 when the dialysis paper is rolled up, thereby causing damage to the dialysis paper.

[0045] In the present embodiment, the top of the flattening roller 42 located at the bottom is located above the pressing plate 22. By setting the top of the flattening roller 42 located at the bottom to be located above the pressing plate 22, when the dialysis paper is rolled up using the present device, the dialysis paper tilts downward along the flattening roller 42 toward the pressing plate 22, so that after the pressing plate 22 presses and positions the top of the rolled up dialysis paper, a gap is created between the unrolled dialysis paper and the rolled up dialysis paper on the winding shaft, so that when the electromagnetic slider 54 is used to displace the blade 53 to cut the dialysis paper, the blade 53 is effectively prevented from contacting the rolled up dialysis paper and causing damage to the rolled up dialysis paper.
