Detailed Description

In the description of the present invention, it is to be understood that the terms "left", "right", "upper", "lower", "front", "rear", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

In order to facilitate the technical solution disclosed in the present invention to be fully understood by those skilled in the art, the following detailed description is made in conjunction with the specific embodiments, and fig. 1 and fig. 2 respectively show the three-dimensional schematic views of the waste film stripping and collecting device in two different states of the present invention, and it can be seen that the waste film stripping and collecting device mainly comprises a frame 1, a material receiving roller assembly 2, a material supporting roller assembly 3, and a power unit 4. Wherein, receipts material roller assembly 2 is horizontal along left and right direction, and it is installed on frame 1, and carries out circumferential direction rotary motion around its self central axis under the drive power effect of power unit 4 to accomplish the collection operation to peeling off the waste film. The number of the material holding roller assemblies 3 is set to 3, and for the sake of convenience of distinction, they are named as a first material holding roller assembly 31, a second material holding roller assembly 32, and a third material holding roller assembly 32, respectively. The first material supporting roller assembly 31, the second material supporting roller assembly 32 and the third material supporting roller assembly 33 are all installed on the frame and are staggered with each other to support and strip the waste film (as shown in fig. 3 and 8). The power unit 4 is arranged on the right side of the frame 1 and comprises an installation base 41, a rotating motor 42, a synchronous belt transmission mechanism 43, a bearing frame 44, a transmission shaft 45, a magnetic powder clutch 46 and a coupler 47. The mounting base 41 is fixed to the floor of the workshop by means of anchor bolts and is completely isolated from the machine frame 1. The magnetic powder clutch 46, the transmission shaft 45 and the coupler 47 are connected in sequence from right to left, and are supported by the bearing frame 44. And the material receiving roller assembly 2 is directly driven by the coupler 47. The rotating motor 42 and the synchronous belt drive 43 cooperate to effect the transfer of power to the magnetic particle clutch 46 (as shown in fig. 3, 4). Therefore, on one hand, the working noise of the synchronous belt transmission mechanism 43 in the running process is extremely low, which is beneficial to ensuring a good working environment in a workshop; on one hand, the synchronous belt transmission mechanism 43 does not slide relatively when working, so that the accuracy of the transmission ratio is ensured, the transmission efficiency is better, and the stable receiving process of the receiving roller assembly 2 is ensured; on the one hand, the transmission ratio of the synchronous belt transmission mechanism 43 can reach a larger value, so that the synchronous belt transmission mechanism has a more compact design structure, and is beneficial to the overall design and spatial layout of the power unit 4.

It should be noted that the mounting base 41 for supporting the rotary motor 42 is completely separated from the frame 1, so as to cut off the transmission path of the dynamic load or the vibration load caused by the operation of the rotary motor 42 to the frame, thereby ensuring that the material receiving roller assembly 2 stably and accurately performs the material receiving operation for peeling off the waste film.

As shown in fig. 5, as a further refinement of the above-described structure of the peeled waste film collecting apparatus, the timing belt drive mechanism 43 includes a driving timing wheel 431, a driven timing wheel 432, and a timing belt 433. The driving synchronizing wheel 431 is sleeved on the power output shaft of the rotating motor 42, and the torque transmission is realized by means of a key connection mode. The driven synchronizing wheel 432 is sleeved on the main shaft of the magnetic powder clutch 46, and torque transmission is realized by means of key connection. The timing belt 433 is simultaneously sleeved on the driving timing wheel 431 and the driven timing wheel 432 to transmit the power.

In addition, as can be seen from fig. 5, the rotating electrical machine 42 is detachably fixed to the mounting base 41 by means of bolts, and correspondingly, coupling through holes for the bolts to pass through are formed in a bottom plate of the rotating electrical machine 42. Preferably, the coupling through-hole is provided as a long waist-shaped hole extending in the front-rear direction, so that when the tension of the synchronous belt 433 cannot meet the use requirement, the bolt is loosened, then the rotating motor 42 is pushed in the front-rear direction to translate, and finally the bolt is locked instantly, so that the whole adjustment process is convenient and fast and is easy to execute.

As shown in fig. 3, 6, 9 and 10, the material receiving roller assembly 2 is preferably a split design structure, specifically: comprises a material receiving roller 21, a bearing mounting sleeve 22, a left rolling bearing 23 and a right rolling bearing 24. The bearing mounting sleeve 22 is detachably fixed to the right side of the housing 1 by means of screws. The left rolling bearing 23 and the right rolling bearing 24 are both assembled in the inner cavity of the bearing mounting sleeve 22, and the distance between the two is not less than 25 mm. The material receiving roller 21 is a cantilever beam structure and sequentially penetrates through the left rolling bearing 23 and the right rolling bearing 24 along the left-to-right direction. Therefore, on one hand, the left end part of the material receiving roller 21 is in a suspended state, so that the formed material roll is convenient to detach, and the whole material receiving roller assembly 2 does not need to be detached integrally; on the other hand, the existence of the bearing mounting sleeve 22 can effectively improve the stability of the material receiving roller 21 in the operation process, and avoid the phenomenon of deflection caused by the action of traction force or the self weight of the material roll.

Finally, it should be noted that the stripping waste film collecting device is additionally provided with a tension detecting unit 5 according to the different characteristics of the wound waste films or the actual requirements of customers, and correspondingly, the rotating motor 42 is selected as a servo motor (as shown in fig. 1). As shown in fig. 3 and 7, the tension detecting unit 5 includes a left tension detector 51 and a right tension detector 52. The left tension detector 51 and the right tension detector 52 are detachably fixed on the left and right side walls of the frame 1, respectively, to support the third material supporting roller assembly 33 together. When the material receiving roller assembly 2 rotates around the central axis thereof to collect the waste film, the left tension detector 51 and the right tension detector 52 detect the lateral pressure on the left end and the right end of the third material supporting roller assembly 33 in real time, feed the obtained pressure values back to the controller in real time, and after data processing, generate control signals to the rotating motor 42 in time to increase or decrease the operating speed thereof, thereby ensuring that the winding tension of the waste film is always maintained in a reasonable level and ensuring the compactness of the formed material roll.
