Description

Technical Field

[0001] The utility model relates to the technical field of waste recycling, in particular to a winding roller mechanism for a trimming machine. Background Art

[0002] At present, during the actual production of monomer packaging bags, the general operation is as follows: Workers first place the rolled packaging raw materials on the placement table, and then use the conveying device to flatten and pull them to the corresponding punching device. The punching device performs punching processing on the packaging raw materials to form monomer packaging bags. Among them, the coordinated work of the conveying device and the punching device can continuously perform punching processing on the packaging raw materials to continuously form multiple monomer packaging bags. However, after multiple packaging bags are formed, multiple continuously hollowed-out and connected trimming materials will be formed on the original integral packaging raw materials.

[0003] Regarding the recycling of trimming materials, generally, a recycling box is set beside the punching device. After punching is completed, the trimming materials will automatically fall into the interior of the recycling box. However, since the trimming materials formed by processing are in a messy and fluffy state, if directly packed into the box, the trimming materials will be in a fluffy state inside the recycling box and occupy a large space. Not only can the maximization of the filling of the recycling box not be achieved, but also the trimming materials in this recycling method are difficult to directly utilize. Based on the defects of the above recycling method, the following recycling method is also proposed in the prior art: A rotatable winding roller is set beside the punching device, and at the same time, a carrier for carrying the winding roller, a driving source for driving the winding roller to rotate, a control source, etc. are added. The above components together form the whole trimming machine. During use, the connected trimming materials are continuously wound and collected by the rotating winding roller. After collecting a certain amount, only need to remove the trimming material roll from the winding roller.

[0004] However, the inventor found in actual use that the recycling method of setting a winding roller also has certain defects. Specifically, the trimming materials are wound around the winding roller in a continuous and tight form. During the winding process, the trimming materials are wound layer by layer on the winding roller. Therefore, after the winding roller continuously collects a certain amount of connected trimming materials, the formed trimming material roll will have a large adhesive connection force with the winding roller. It is difficult to remove the annular trimming material roll from the winding roller solely by manual labor, and hydraulic tools, etc. need to be used for assistance operations, making this material removal process more cumbersome and time-consuming, and it is difficult to make the winding roller quickly resume the next recycling work.

[0005] Therefore, the inventor improved the conventional winding roller structure to solve the above problems. Summary of the Utility Model

[0006] The purpose of the present utility model is to propose a winding roller mechanism for a scrap material machine to solve the problems in the prior art. The winding roller mechanism improves the winding roller. Before the winding roller works, its outer diameter can be enlarged so that it can wind with a larger outer diameter. After winding is completed, the outer diameter of the winding roller can be restored, creating a gap between the scrap material roll and the winding roller, facilitating the smooth removal of the scrap material roll.

[0007] To solve the above problems, the present utility model provides the following technical solutions:

[0008] A winding roller mechanism for a scrap material machine includes a winding roller with grooves on its outer circumference and an expanding strip movably arranged on the grooves. The expanding strip has a first working state of being received into the grooves and a second working state of extending out of the groove openings. The winding roller mechanism further includes a driving member arranged on the winding roller and used to drive the expanding strip to move in the grooves, so that the expanding strip can be switched between the first working state and the second working state.

[0009] As a further solution of the present utility model: The driving member includes two pushing blocks arranged in the grooves. The two pushing blocks respectively abut against both ends of the expanding strip, and the sides of the two pushing blocks abutting against the expanding strip are both set as inclined wedge surfaces, so that when the two pushing blocks move closer, the expanding strip can be driven and extended out of the grooves; The driving member further includes an elastic member arranged in the grooves, and the elastic member is connected to the expanding strip, and the elastic member is used to make the expanding strip have a moving tendency to move towards the bottom of the grooves.

[0010] As a further solution of the present utility model: The driving member further includes a rotating shaft rotatably installed on the grooves, and the rotating shaft is arranged along the length direction of the winding roller. The rotating shaft has two thread sections with opposite threads, and the two pushing blocks are respectively thread sleeved on the corresponding thread sections.

[0011] As a further solution of the present utility model: The groove width of the grooves is arranged along the radial direction of the winding roller, so that the movement of the expanding strip in the grooves is along the radial direction of the winding roller.

[0012] As a further solution of the present utility model: The grooves, the expanding strip and the driving member together form a set of expanding components, and multiple sets of expanding components are arranged in a circumferential array along the winding roller.

[0013] As a further solution of the present utility model: Rolling wheels are rotatably arranged at both bottom ends of the expanding strip, so that the bottom end of the expanding strip and the inclined wedge surface of the pushing block are in rolling connection.

[0014] As a further solution of the present utility model: The elastic member is a return spring arranged in the grooves, and one end of the return spring is connected to the expanding strip.

[0016] As a further solution of the utility model: a guide rod is fixedly arranged on the connecting block, and the top end of the guide rod is movably inserted into the diameter-expanding long strip, and the return spring is sleeved outside the guide rod.

[0017] As a further solution of the utility model: both ends of the rotating shaft extend out of the groove.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] 1. Through the arrangement of the diameter-expanding long strip, the diameter-expanding long strip has a storage state and an extended state. When the diameter-expanding long strip is in the extended state, it can drive the winding roller to rotate accordingly until the winding roller winds a certain amount of corner materials, and then drive the diameter-expanding long strip to change into the storage state. At this time, there will be a certain gap between the corner material roll and the winding roller, and the corner material roll can be easily removed from the winding roller, which is convenient for taking materials;

[0020] 2. Through the arrangement of the driving member, the staff can drive the rotating shaft to rotate, so that the two push blocks move closer or away from each other. The closer movement of the two push blocks can drive the diameter-expanding long strip to extend out of the groove, and the separating movement of the two push blocks and the action of the elastic member can drive the diameter-expanding long strip to be received into the groove, realizing the rapid switching of the diameter-expanding long strip between two working states;

[0021] 3. Through the arrangement that the rotating shaft extends out of the groove, when it is necessary to drive the rotating shaft to rotate, an L-shaped handle can be installed at one end of the rotating shaft outside the groove, and the L-shaped handle can be used to smoothly drive the rotating shaft to rotate;

[0022] 4. Through the arrangement of the guide rod, the insertion cooperation between the guide rod and the diameter-expanding long strip can play a certain guiding role for the diameter-expanding long strip, so that the diameter-expanding long strip can only move along the width direction of the groove;

[0023] 5. The groove, the diameter-expanding long strip and the driving member together form a set of diameter-expanding components, and multiple sets of diameter-expanding components are arranged in a circumferential array along the winding roller. By using this arrangement, the gap between the corner material roll and the winding roller can be increased, and the blanking work after winding can be better carried out;

[0024] 6. By rotatably arranging rollers at both bottom ends of the diameter-expanding long strip, the bottom end of the diameter-expanding long strip is in rolling connection with the inclined wedge surface of the push block, changing the original sliding connection to rolling connection, reducing the frictional resistance, and making the movement of the diameter-expanding long strip smoother.

[0036] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0037] Such as Figures 1-9As shown in the figure, a winding roller mechanism for a scrap material machine includes a winding roller 1 installed at a corresponding position. The winding roller 1 can rotate under the drive of an external force to continuously collect the connected scrap materials. The innovation of the present utility model lies in that a groove 2 is formed on the outer circumference of the winding roller 1. The groove 2 has a groove bottom, a groove opening, and two groove ends. An expanding strip 3 is movably arranged on the groove 2. The expanding strip 3 has a first working state and a second working state on the groove 2. When the expanding strip 3 is in the first working state, the expanding strip 3 is received into the groove 2. This state can be represented by Figure 2 ; when the expanding strip 3 is in the second working state, one end of the expanding strip 3 extends out of the groove opening of the groove 2. This state can be represented by Figure 3 .

[0038] As Figures 1-4 shown, before the winding work of the scrap materials, the expanding strip 3 is first in the second working state. The presence of the expanding strip 3 can increase the outer circumference size of the winding roller 1. During the subsequent winding work, the scrap materials will be wound around the whole formed by the winding roller 1 and the expanding strip 3, and the part of the scrap materials in contact with the expanding strip 3 will be in a bulging shape. After the winding is completed, the expanding strip 3 can be changed to the first working state. At this time, the expanding strip 3 is received into the groove 2. Furthermore, a certain gap will be generated between the scrap material roll and the winding roller 1. At this moment, the scrap material roll and the winding roller 1 are in a freely movable state, and the scrap material roll can be easily and smoothly removed from the winding roller 1 without the need for external force, and the unloading is convenient.

[0039] As Figures 2-3As shown in the figure, in order to conveniently and quickly switch the expanded long strip 3 between the first working state and the second working state, a driving member is provided on the winding roller 1. The driving member is used to drive the expanded long strip 3 to move in the groove 2, that is, to realize the action of the expanded long strip 3 being received into the groove 2 or extending out of the groove 2. Specifically, the driving member includes two push blocks 4 arranged in the groove 2. The two push blocks 4 respectively abut against both ends of the expanded long strip 3, and the sides of the two push blocks 4 abutting against the expanded long strip 3 are both set as inclined wedge surfaces. The two push blocks 4 can move closer or away from each other under the action of an external force. Then, when the two push blocks 4 move closer to each other, the distance between the inclined wedge surfaces on the two push blocks 4 gradually decreases, so that the expanded long strip 3 is driven to move out of the groove 2 until one end of the expanded long strip 3 extends out of the groove 2, which is the second working state. When driving the two push blocks 4 to move away from each other, in order for the expanded long strip 3 to move back to the bottom of the groove 2, the driving member further includes an elastic member 5 arranged in the groove 2, and the elastic member 5 is connected to the expanded long strip 3. The elastic member 5 is used to make the expanded long strip 3 have a tendency to move towards the bottom of the groove 2. Specifically, when the expanded long strip 3 moves out of the groove 2, the elastic member 5 will be stretched. Then, when driving the two push blocks 4 to move away from each other, under the pulling action of the elastic member 5 on the expanded long strip 3, the expanded long strip 3 can move back to the groove 2 until it is in the first working state.

[0040] As Figure 9 shown, when the two push blocks 4 move closer to each other, in order for the two push blocks 4 to smoothly drive the expanded long strip 3 to move, in some possible embodiments, rollers 7 are rotatably arranged at both bottom ends of the expanded long strip 3, so that the bottom end of the expanded long strip 3 and the inclined wedge surface of the push block 4 are in rolling connection, changing the original sliding connection to a rolling connection, reducing the frictional resistance, and making the movement of the expanded long strip 3 smoother.

[0041] As Figure 4 shown, for the setting of the elastic member 5 described above, the elastic member 5 can be a rubber strip or a return spring, etc. When the elastic member 5 is set as a return spring, the return spring is arranged in the groove 2, and one end of the return spring is connected to the expanded long strip 3. During the process of the expanded long strip 3 extending out of the groove 2, the return spring is stretched; when the two push blocks 4 move away from each other, relying on the elastic reset force of the return spring, the expanded long strip 3 is pulled towards the bottom of the groove 2 to the received state.

[0042] In order to enable the two push blocks 4 to perform corresponding actions, the driving member is further provided with a rotating shaft 6 rotatably installed on the groove 2, and the rotating shaft 6 is arranged along the length direction of the winding roller 1. Specifically, a connecting block 8 can be fixedly arranged at the bottom of the groove 2, and the rotating shaft 6 is rotatably installed on the connecting block 8. The rotating shaft 6 has two thread segments with opposite threads, and the two push blocks 4 are respectively thread sleeved on the corresponding thread segments. When driving the rotating shaft 6 to rotate, the two push blocks 4 can move closer or away from each other.

[0043] As Figures 1-3 shown, in order to facilitate the staff to drive the rotation of the rotating shaft 6, both ends of the rotating shaft 6 can extend out of the groove 2. When it is necessary to drive the two push blocks 4 to work, the staff can buckle the L-shaped handle to one end of the rotating shaft 6, and driving the L-shaped handle can drive the rotating shaft 6 to rotate. After use, the L-shaped handle can be disassembled.

[0044] As Figures 2-4 shown, it should be noted that the reserved size inside the groove 2 only enables the two push blocks 4 to slide only along the length direction of the groove 2 in the groove 2 and cannot rotate on its own. That is to say, the groove 2 will perform a certain guiding and limiting function on the two push blocks 4 to cooperate with the driving action of the rotating shaft 6 on the two push blocks 4. In order to make the groove 2 play a guiding and limiting role on the diameter-expanding long strip 3, a guiding rod 9 can be fixedly arranged on the connecting block 8, and the top end of the guiding rod 9 is movably inserted into the diameter-expanding long strip 3. The insertion cooperation between the guiding rod 9 and the diameter-expanding long strip 3 can play a certain guiding role on the diameter-expanding long strip 3. At the same time, on the basis of setting the guiding rod 9, a return spring can also be sleeved outside the guiding rod 9.

[0045] As Figure 5 and Figure 7 shown, preferably, the groove width of the groove 2 is arranged radially along the winding roller 1, so that the movement of the diameter-expanding long strip 3 in the groove 2 is along the radial direction of the winding roller 1.

[0046] Furthermore, in order to increase the gap between the scrap material roll and the winding roller 1, the groove 2, the diameter-expanding long strip 3 and the driving member can jointly form a set of diameter-expanding components, and multiple sets of diameter-expanding components are arranged in a circumferential array along the winding roller 1. As Figures 7-8 can be seen, this embodiment shows the situation of setting four sets of diameter-expanding components. Of course, in the actual production process, it is not limited to setting four sets of diameter-expanding components. The corresponding number of diameter-expanding components can also be set according to working conditions such as the type of scrap material, so that the scrap material roll can be separated from the winding roller 1 in a better state.

[0047] The above has described an embodiment of the present invention in detail, but the content described is only the preferred embodiment of the present invention and cannot be considered as used to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
