A material collecting device applicable to a perforated waste strip

Abstract

The present invention relates to a take-up device applicable to a perforated waste tape, which comprises a cabinet, a take-up assembly, a rotary drive unit, a waste tape twisting unit and a material supporting roller assembly. The take-up assembly includes a transmission shaft and a take-up reel. The rotary drive unit drives the transmission shaft to perform a circumferential rotary motion around its own central axis to complete the collection operation of the perforated waste tape. The material supporting roller assembly is arranged on the right side of the take-up assembly to support the perforated waste tape. The waste tape twisting unit is supported by the front side wall of the cabinet and is arranged between the take-up assembly and the material supporting roller assembly. During the process that the perforated waste tape flows through the waste tape twisting unit, it is twisted from a flat state to a twist state under the action of a twisting force. In this way, some of the dug holes on it are effectively filled, thereby greatly increasing the density of the waste tape, ensuring that the waste tape after being wound into a roll has high compactness and a relatively small forming volume.

Description

Technical Field

[0001] The present invention relates to the technical field of non-standard equipment manufacturing, and in particular to a material collecting device suitable for a waste strip with holes. Background Art

[0002] A filter cartridge is equipped with a certain type of activated carbon agent, and is a device that removes dust and toxic and harmful gases in the air through the principles of physical adsorption and chemical reaction for people to breathe. It is usually used in conjunction with a gas mask. There is a layer of smoke filter layer inside the filter cartridge for filtering out smoke particles, and the filtering elements include filter paper, fiberglass or filter cotton, etc.

[0003] Taking a filter cotton block as an example, it is directly punched from a face belt. When the filter cotton block detaches from the face belt, a series of linearly arrayed punched holes will inevitably be formed on the face belt. When the waste strip with holes is wound by a material collecting device, due to the punched holes not being effectively filled, the compactness of the wound waste strip with holes is poor. That is, on the premise that the weight of the waste cotton strip with holes to be wound is certain, the volume of the wound roll is significantly larger, which is not convenient for subsequent storage and transportation. Therefore, it is urgent for technicians to solve the above problems. Summary of the Invention

[0004] Therefore, in view of the above existing problems and defects, the designers of the present invention collected relevant materials, through multi-party evaluation and consideration, and through continuous experiments and modifications by technicians with many years of R & D experience in this industry, finally led to the emergence of the material collecting device suitable for a waste strip with holes.

[0005] In order to solve the above technical problems, the present invention relates to a material collecting device suitable for a waste strip with holes, which includes a cabinet, a material collecting assembly, a rotary driving unit, a waste strip twisting unit, and a material supporting roller assembly. The material collecting assembly is installed on the front side wall of the cabinet, and includes a transmission shaft and a material collecting disk. The material collecting disk is sleeved on the transmission shaft and rotates synchronously with the transmission shaft. The rotary driving unit is built in the inner cavity of the cabinet, and drives the transmission shaft to perform circumferential rotational movement around its own central axis to complete the collection operation of the waste strip with holes. The material supporting roller assembly is also installed on the front side wall of the cabinet and is arranged on the right side of the material collecting assembly to support the waste strip with holes. The waste strip twisting unit is supported by the front side wall of the cabinet and is arranged between the material collecting assembly and the material supporting roller assembly. During the process that the waste strip with holes flows through the waste strip twisting unit, it is twisted from a flat shape to a twist shape under the action of the twisting force.

[0006] As a further improvement of the technical solution of the present invention, the waste strip torsion unit includes a load-bearing frame, a first left-side guide roller, a second left-side guide roller, a first right-side guide roller, and a second right-side guide roller. The first left-side guide roller, the second left-side guide roller, the first right-side guide roller, and the second right-side guide roller are all inserted into the cavity of the load-bearing frame. Among them, the first left-side guide roller and the second left-side guide roller are both horizontally arranged, arranged side by side in the up-down direction, and spaced apart by a set distance from each other to form a horizontally arranged left passing slot for the perforated waste strip to pass through. The first right-side guide roller and the second right-side guide roller are both vertically arranged, arranged side by side in the front-back direction, and spaced apart by a set distance from each other to form a vertically arranged right passing slot for the perforated waste strip to pass through.

[0007] As a further improvement of the technical solution of the present invention, the front and rear ends of the first left-side guide roller are fixed to the load-bearing frame by means of first screws. Correspondingly, on the front and rear side walls of the load-bearing frame, first left-side waist-shaped holes for the first screws to pass through and extending in the up-down direction are provided. The front and rear ends of the second left-side guide roller are fixed to the load-bearing frame by means of second screws. Correspondingly, on the front and rear side walls of the load-bearing frame, second left-side waist-shaped holes for the second screws to pass through and extending in the up-down direction are provided. The upper and lower ends of the first right-side guide roller are fixed to the load-bearing frame by means of third screws. Correspondingly, on the upper and lower side walls of the load-bearing frame, first right-side waist-shaped holes for the third screws to pass through and extending in the front-back direction are provided. The upper and lower ends of the second right-side guide roller are fixed to the load-bearing frame by means of fourth screws. Correspondingly, on the upper and lower side walls of the load-bearing frame, second right-side waist-shaped holes for the fourth screws to pass through and extending in the front-back direction are provided.

[0008] As a further improvement of the technical solution of the present invention, the rotation drive unit includes a support frame, a rotation motor, and a synchronous belt drive mechanism. The support frame is welded and fixed in the inner cavity of the cabinet and is arranged directly below the transmission shaft. The rotation motor is detachably fixed to the support frame. The synchronous belt drive mechanism includes a driving synchronous pulley, a first driven synchronous pulley, and a synchronous belt. The driving synchronous pulley is sleeved on the power output shaft of the rotation motor and transmits torque by means of a key connection. The first driven synchronous pulley is sleeved on the transmission shaft and transmits torque by means of a key connection. The synchronous belt is simultaneously sleeved on the driving synchronous pulley and the first driven synchronous pulley to transmit power.

[0009] As a further improvement of the technical solution of the present invention, the rotation drive unit also includes an angular displacement detection unit. The angular displacement detection unit includes a support plate, a rotating shaft, an angular displacement sensor and a second driven synchronous wheel. The support plate is fixed to the support frame to support the rotating shaft. The angular displacement sensor is arranged directly behind the rotating shaft to measure the rotation angle of the rotating shaft per unit time. The second driven synchronous wheel is sleeved on the rotating shaft and is always meshed with the synchronous belt.

[0010] As a further improvement of the technical solution of the present invention, the support roller assembly includes a first support roller and a second support roller. The first support roller and the second support roller are arranged side by side and separated by a set distance. The receiving device suitable for the waste belt with holes also includes a gravity tensioning unit. The gravity tensioning unit is supported by the front side wall of the cabinet and is arranged directly below the first support roller and the second support roller to always tension the waste belt with holes.

[0011] As a further improvement of the technical solution of the present invention, the gravity tensioning unit includes an upper mounting seat, a lower mounting seat, a guide rod assembly, a counterweight sliding block and a tensioning roller. The upper mounting seat and the lower mounting seat can be detachably fixed on the front side wall of the cabinet, and are relatively positioned to be used to fix the guide rod assembly. The tensioning roller always pulls the perforated waste belt and is assembled as a whole with the counterweight sliding block. The counterweight sliding block is sleeved on the guide rod assembly and slides directionally along the up and down directions.

[0012] As a further improvement of the technical solution of the present invention, the receiving device for the waste belt with holes also includes a linear drive unit. The linear drive unit is fixed to the front side wall of the cabinet to drag the waste belt twisting unit to perform reciprocating displacement motion along the front and rear directions.

[0013] As a further improvement of the technical solution of the present invention, the linear drive unit includes a support seat and a ball screw linear module. The support seat is installed on the front side wall of the cabinet to support the ball screw linear module. The ball screw linear module directly drags the scrap belt torsion unit.

[0014] Compared with the receiving device of the traditional design structure, the technical solution disclosed in the present invention is suitable for the receiving operation of the waste belt with holes. Before the receiving assembly formally receives the material, the waste belt is first pre-processed by means of the waste belt twisting unit arranged upstream thereof, so that it is twisted from a flat state to a twisted state, so that part of the holes on it are effectively filled, thereby greatly improving the density of the waste belt, that is, reducing the space occupied by the unit weight of the waste belt, ensuring that the waste belt after rolling has a high density and a relatively small molding volume, which is conducive to subsequent storage and transportation operations.

Detailed implementation manners

[0027] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "left", "right", "upper", "lower", "front", "rear", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0028] For the convenience of those skilled in the art to fully understand the technical solutions disclosed by the present invention, the following further describes the content of the present invention in detail with reference to specific embodiments. Figure 1 、 Figure 2 、 Figure 3 FIGS. 14 and 15 respectively show the three-dimensional schematic diagram and the front view of the material receiving device applicable to the waste belt with holes in two different states of the present invention. It can be seen that it mainly consists of a cabinet 1, a material receiving assembly 2, a rotary drive unit 3, a waste belt torsion unit 4, a material supporting roller assembly 5, etc. The material receiving assembly 2 is installed on the front side wall of the cabinet 1, and it includes a transmission shaft 21 and a material receiving disk 22. The material receiving disk 21 is sleeved on the transmission shaft 21 and rotates synchronously with the transmission shaft 21 (such as Figure 4As shown in [figure]. The rotation drive unit 3 is built into the inner cavity of the cabinet 1, and it drives the transmission shaft 21 to perform a circumferential rotational motion around its own central axis to complete the collection operation of the perforated waste belt. The material supporting roller assembly 5 is also installed on the front side wall of the cabinet 1 and is arranged on the right side of the material collecting assembly 2 to support the perforated waste belt. The waste belt torsion unit 4 is supported by the front side wall of the cabinet 1 and is arranged between the material collecting assembly 2 and the material supporting roller assembly 5. During the process of the perforated waste belt flowing through the waste belt torsion unit 4, it is twisted from a flat state to a twist-like state under the action of the torsion force. In this way, as Figure 10 shown in [figure], before the material collecting assembly 2 starts the formal material collection, first, the waste belt is pretreated by the waste belt torsion unit 4 arranged upstream of it to cause it to undergo torsional deformation, so that some of the holes dug on the waste belt are effectively filled, thereby greatly increasing the density of the perforated waste belt, that is, reducing the space occupied by the waste belt per unit weight, ensuring that the coiled waste belt has high density, and the formed volume is relatively small, which is conducive to subsequent storage and transportation operations.

[0029] Figure 6 The [figure] shows a three-dimensional schematic diagram of the waste belt torsion unit in the material collecting device for perforated waste belts applicable to the present invention. It can be seen that it mainly consists of a load-bearing frame 41, a first left guide roller 42, a second left guide roller 43, a first right guide roller 44, and a second right guide roller 45, etc. Among them, the first left guide roller 42, the second left guide roller 43, the first right guide roller 44, and the second right guide roller 45 are all inserted into the cavity of the load-bearing frame 41. Among them, the first left guide roller 42 and the second left guide roller 43 are both in a horizontal position, arranged side by side along the up-down direction, and spaced a set distance from each other to form a left through slot 46 for the perforated waste belt to pass through and be horizontally placed. The first right guide roller 44 and the second right guide roller 45 are both in a vertical position, arranged side by side along the front-back direction, and spaced a set distance from each other to form a right through slot 47 for the perforated waste belt to pass through and be vertically placed. During the process of the waste belt being collected, it first undergoes a first twist through the right through slot 47, and then undergoes a second twist through the left through slot 46, and finally completes the deformation from a flat state to a twist-like state. The width of the right through slot 47 is set according to the thickness value t of the waste belt to be pre-passed through, and the width of the left through slot 46 is set according to the maximum diameter of the waste belt after the first twist forming. Generally, the unilateral gap can be controlled between 1 / 10t - 3 / 10t.

[0030] The waste strip torsion unit 4 is arranged by adopting the above technical solution, and mainly achieves the following beneficial technical effects: 1) Ensure that the waste strip has good quickness and smoothness during the torsion deformation process, and avoid the occurrence of "jamming" phenomena; 2) The waste strip torsion unit 4 does not require power transmission during the working process, and only needs to rely on the pulling force received by the waste strip to realize the torsion of its own shape; 3) The structural design of the waste strip torsion unit 4 is simple, and it is easy to manufacture and implement.

[0031] It can also be seen from Figure 6 that preferably, both the front and rear ends of the first left-mounted guide roller 42 are fixed to the load-bearing frame by means of the first screw; both the front and rear ends of the second left-mounted guide roller 43 are preferably fixed to the load-bearing frame 41 by means of the second screw; both the upper and lower ends of the first right-mounted guide roller 44 are preferably fixed to the load-bearing frame by means of the third screw; both the upper and lower ends of the second right-mounted guide roller 45 are preferably fixed to the load-bearing frame 41 by means of the fourth screw. Correspondingly, as shown in Figure 7 it is shown that on both the front and rear side walls of the load-bearing frame 41, first left-mounted waist-shaped holes 411 extending in the up and down direction for the first screw to pass through are provided; on both the front and rear side walls of the load-bearing frame 41, second left-mounted waist-shaped holes 412 extending in the up and down direction for the second screw to pass through are provided; on both the upper and lower side walls of the load-bearing frame 41, first right-mounted waist-shaped holes 413 extending in the front and rear direction for the third screw to pass through are provided; on both the upper and lower side walls of the load-bearing frame 41, second right-mounted waist-shaped holes 414 extending in the front and rear direction for the fourth screw to pass through are provided. In this way, when the thickness or width of the pre-wound waste strip changes, it is convenient to quickly adjust the slit widths of the left through-slit 46 and the right through-slit 47. The specific operation steps are as follows: As shown in Figure 6 it is shown that when it is necessary to adjust the slit width of the left through-slit 46, first loosen the first screw and the second screw, and drag the first left-mounted guide roller 42 and the second left-mounted guide roller 43 in the up and down direction until the slit width meets the design requirements, and then immediately lock the first screw and the second screw; when it is necessary to adjust the slit width of the right through-slit 47, first loosen the third screw and the fourth screw, and drag the first right-mounted guide roller 44 and the second right-mounted guide roller 45 in the front and rear direction until the slit width meets the design requirements, and then immediately lock the third screw and the fourth screw.

[0032] It is known that the rotary drive unit 3 can adopt various design structures to drive the transmission shaft. However, here a design scheme with simple structure, easy to manufacture and implement, and convenient for later maintenance is recommended, specifically as follows: As shown in Figure 4As shown in the figure, the rotary drive unit 3 includes a support frame 31, a rotary motor 32, and a synchronous belt drive mechanism 33. The support frame 31 is welded and fixed in the inner cavity of the cabinet 1 and is arranged directly below the transmission shaft 21. The rotary motor 32 is detachably fixed on the support frame 31. As Figure 3 , 5 As shown in the figure, the synchronous belt drive mechanism 33 includes a driving synchronous pulley 331, a first driven synchronous pulley 332, and a synchronous belt 333. The driving synchronous pulley 331 is sleeved on the power output shaft of the rotary motor 32, and torque transmission is achieved by means of a key connection. The first driven synchronous pulley 332 is sleeved on the transmission shaft 21, and torque transmission is achieved by means of a key connection. The synchronous belt 333 is simultaneously sleeved on the driving synchronous pulley 331 and the first driven driving pulley 332 to transmit power. In this way, on the one hand, the synchronous belt drive mechanism 33 has extremely low working noise during operation, which is beneficial to ensuring a good working environment in the workshop; on the other hand, since there is no relative slip when the synchronous belt drive mechanism 33 works, the accuracy of the transmission ratio is ensured, and it has good transmission efficiency; on the other hand, the transmission ratio of the synchronous belt drive mechanism 33 can reach a relatively large value, so that it has a relatively compact design structure, which is conducive to the overall design and spatial layout of the rotary drive unit 3.

[0033] For the convenience of detecting the total number of rotations of the receiving tray 22 per unit time, and then indirectly converting the collection amount of the waste belt on the receiving tray 22, the rotary drive unit 3 is additionally provided with an angular displacement detection unit 34 as required. As Figure 3 , 5 As shown in the figure, the angular displacement detection unit 34 includes a support plate 341, a rotating shaft (not shown in the figure), an angular displacement sensor 342, and a second driven synchronous pulley 343. The support plate 341 is fixed on the support frame 31 to support the rotating shaft. The angular displacement sensor 342 is arranged directly behind the rotating shaft to measure the rotation angle of the rotating shaft per unit time, that is, indirectly obtain the total number of rotations of the receiving tray 22. The second driven synchronous pulley 343 is sleeved on the rotating shaft and is always engaged with the synchronous belt 333.

[0034] As Figure 1 , 2 As shown in the figure, the material supporting roller assembly 5 is composed of a first material supporting roller 51 and a second material supporting roller 52. The first material supporting roller 51 and the second material supporting roller 52 are arranged side by side in the left-right direction and are spaced apart by a set distance. Here, it should be emphasized that the receiving device for the perforated waste belt can also be additionally provided with a gravity tensioning unit 6 according to the actual situation on site or customer requirements. The gravity tensioning unit 6 is supported by the front side wall of the cabinet 1 and is arranged directly below the first material supporting roller 51 and the second material supporting roller 52 to always tension the perforated waste belt. As Figure 8As shown in the figure, the gravity tensioning unit 6 includes an upper mounting seat 61, a lower mounting seat 62, a guide rod assembly 63, a counterweight sliding block 64, and a tensioning roller 65. The upper mounting seat 61 and the lower mounting seat 62 are detachably fixed to the front side wall of the cabinet 1 and are in relative positions to jointly fix the guide rod assembly 63. The tensioning roller 65 always pulls the perforated waste belt and is assembled with the counterweight sliding block 64 as a whole. The counterweight sliding block 64 is sleeved on the guide rod assembly 63 and slides directionally along the up and down direction. During the process of conveying the waste belt, the tensioning roller 65 always presses against the waste belt, while the counterweight sliding block 64 always slides adaptively along the guide rod assembly 63. The tensioning roller 65 and the counterweight sliding block 64 cooperate with each other to achieve the tensioning of the waste belt by means of the self-weight of the counterweight sliding block 64.

[0035] In addition, as can also be seen from Figure 1 When the width of the material receiving disc 22 itself is relatively large, the material receiving device applicable to the perforated waste belt can also be additionally provided with a linear drive unit 7 according to the actual situation. The linear drive unit 7 is fixed to the front side wall of the cabinet 1 to drive the waste belt twisting unit to perform reciprocating displacement motion along the front and back directions (as Figure 1 shown in the figure). In this way, during the actual winding process of the waste belt, the linear drive unit 7 drives the waste belt twisting unit 4 to perform linear motion reciprocally, so that the twisted waste belt is arranged sequentially along the axial direction of the material receiving disc 22 to increase its storage capacity. It should be noted that during the winding process, the linear displacement speed of the linear drive unit 7 needs to be strictly controlled to ensure the compactness of the arrangement of the waste belt on the material receiving disc 22.

[0036] Finally, it should be noted that it is known that the linear drive unit 7 can adopt various design structures to achieve the reciprocating drive of the waste belt twisting unit 4. However, a preferred implementation scheme is recommended as follows: As Figure 9 shown in the figure, the linear drive unit 7 includes a support seat 71 and a ball screw linear module 72. The support seat 71 is installed on the front side wall of the cabinet 1 to support the ball screw linear module 72. The ball screw linear module 72 directly drives the displacement of the waste belt twisting unit 4.

Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
