The disclosure of the present invention will be further described in detail with reference to the following embodiments, and fig. 1 and fig. 2 respectively show the three-dimensional schematic diagrams of two different viewing angles of the concrete troweling pan film wrapping device of the present invention, and it can be understood that the troweling pan film wrapping device is composed of two parts, i.e. a plastic film releasing part 1 and a packaging wrapping part 2. The plastic film discharging part 2 is applied in cooperation with the package winding part 1 and is disposed at the left side of the package winding part 1 to continuously supply the band-shaped plastic film thereto. The troweling tray is supported by the wrapping and winding portion 2 and is always kept in a standing state. When the floating plate is acted by external force, it can freely implement composite rotary motion, and along with the continuous propulsion of said process, the strip-shaped plastic film can be winded and wrapped on it in the mutually-staggered state.

Fig. 3 is a schematic perspective view showing a wrapping portion of the wrapping film device for a concrete troweling plate according to the present invention, and it is understood that the wrapping film device is mainly composed of a top holder portion 21, a pivoting support portion 22, and the like. Wherein the trowelling disc is directly jacked by the top of the tray 21 and is free to perform a circumferential rotational movement around its central axis when subjected to a toggle force. The top part 21 is borne by the revolving movement support 22 and is free to perform a horizontal rotating movement when it is subjected to a lateral thrust, during which the troweling tray follows the rotation.

Before the film winding operation is performed on the leveling plate, the leveling plate is placed on the holder top part 21 in advance, then the plastic film drawn out through the plastic film releasing part 2 is manually wound on the leveling plate for at least one circle in advance, then a worker continuously rotates the leveling plate (with the central axis of the rotary motion supporting part 22 as a rotation reference), the plastic film released through the plastic film releasing part 2 is wrapped and wound along the diameter direction of the leveling plate, then the worker rotates the leveling plate again (with the central axis of the leveling plate as a rotation reference), the plastic film released through the plastic film releasing part 2 is continuously wrapped and wound on the outer contour edge of the leveling plate, and the above process is repeated until the leveling plate is completely wrapped and wound by the strip-shaped plastic film.

In practical application, the concrete floating disc film winding device at least achieves the following beneficial effects:

1) On the premise of no external force assistance, the placed leveling disc can be independently kept in a vertical state in the film winding process, and in the film winding operation process, a worker only needs to output a rotating torque to rotate the leveling disc without bearing the overturning torque caused by the self weight of the leveling disc;

2) Due to the existence of the packaging winding part 2, the vertical height of the floating plate is reasonably improved (the packaging winding parts 2 with different specifications and heights can be selected and matched according to the difference of the measured diameter values of the floating plate), so that the smooth and efficient development of film winding work is facilitated, and the film winding time of the single floating plate is reduced to be within 5 min;

3) Because of the workman need not to bear the overturning moment that causes because of the dish dead weight of floating to reserve abundant strength, energy for the workman and control the rotating uniform velocity nature of floating the dish, and then make the winding quality of banded plastic film obtain guaranteeing, ensure finally that floating the dish and obtain regular packing.

It is known that, according to common design knowledge, the top rest 21 can take a plurality of designs to achieve a reliable top rest for the trowel plate, however, an embodiment is proposed herein that is simple in design, easy to manufacture and implement, and at a later stage facilitates the performance of rework, retrofit operations, as follows: as shown in fig. 4, 5 and 7, the top bracket 21 is mainly composed of a first shaped force bearing plate 211, a second shaped force bearing plate 212, a first cross bracket component 213 and a second cross bracket component 214. Wherein, the first special-shaped bearing plate 211 and the second special-shaped bearing plate 223 are both borne by the rotary motion supporting part 22. The first special-shaped bearing plate 211 and the second special-shaped bearing plate 212 are oppositely arranged to form an embedded gap between the two. And assuming that the thickness value of the leveling disc is a and the width value of the embedded gap is b, the b-a is more than or equal to 3mm and less than or equal to 5mm. The first transverse support component 213 and the second transverse support component 214 are cooperatively borne by the first special-shaped bearing plate 211 and the second special-shaped bearing plate 212 and cross the embedded gap. The first cross brace member 213 and the second cross brace member 214 are parallel to each other and maintained at the same level. When the trowel is erected into position relative to the insertion space, it is lifted by the cooperation of the first cross brace assembly 213 and the second cross brace assembly 214.

Furthermore, in order to avoid the phenomenon that the trowelling disk accidentally falls off over the first cross support component 213 and the second cross support component 214 due to the action of external force, in the actual manufacturing process, the distance value c between the first cross support component 213 and the second cross support component 214 needs to be controlled, and if the diameter value of the trowelling disk is d, c is more than or equal to 1/2d and less than or equal to 4/5d, so that the lower gravity center line of the trowelling disk can be effectively ensured to be always kept between the first cross support component 213 and the second cross support component 214 when the trowelling disk is circumferentially rotated.

As can be seen from the above description, the flexibility of the first and second traverse support assemblies 213 and 214 directly determines the amount of torque that the trowel disc is driven to perform the circumferential rotation movement and that the worker needs to output, and therefore, as a further optimization of the above technical solution, the first traverse support assembly 213 is mainly composed of several parts, such as a first rotation support assembly 2131, a first support shaft 2132, and a second rotation support assembly 2133, as shown in fig. 6. The first rotation support assembly 2131 includes a first bearing seat 21311 and a first bearing 21312. The first bearing seat 21311 is detachably fixed on the outer side wall of the first special-shaped bearing plate 211 by screws. The second rotation support assembly 2133 includes a second bearing seat 21331 and a second bearing 21332. The second bearing seat 21331 is detachably fixed on the outer side wall of the second special-shaped bearing plate 212 by screws. The first bearing 21312 and the second bearing 21332 are respectively embedded in the first bearing seat 21311 and the second bearing seat 21331 in a one-to-one correspondence manner. The first support shaft 2132 for directly pushing against the trowel plate is cooperatively borne by the first bearing 21312 and the second bearing 21332, and is free to perform a circumferential rotational motion about its central axis.

For the same design purpose, the second cross support assembly 214 may also be designed with reference to the structure of the first cross support assembly 213, as shown in fig. 8, the second cross support assembly 214 is mainly composed of a third rotation support assembly 2141, a second support shaft 2142, and a fourth rotation support assembly 2143. The third rotation support assembly 2141 includes a third bearing seat 21411 and a third bearing 21412. The third bearing seat 21411 is detachably fixed to the outer sidewall of the first special-shaped bearing plate 211 by screws. The fourth rotation support assembly 2143 includes a fourth bearing seat 21431 and a fourth bearing 21432. The fourth bearing seat 21431 is detachably fixed to the outer sidewall of the second special-shaped bearing plate 212 by screws. The third bearings 21412 and the fourth bearings 21432 are respectively embedded in the third bearing seat 21411 and the fourth bearing seat 21431 in a one-to-one correspondence manner. The second support shaft 2142 for directly pushing against the troweling plate is cooperatively borne by the third bearing 21412 and the fourth bearing 21432, and is free to perform a circumferential rotational motion about its central axis. In the process of performing the film winding operation, a worker continuously stirs the troweling plate (the first support shaft 2132 and the second support shaft 2142 continuously perform circumferential rotation around the central axis thereof due to the transmission force), the troweling plate is rotated following the central axis thereof, and at the same time, the plastic film released through the plastic film releasing portion 2 wraps and winds the outer peripheral edge of the troweling plate.

As a further refinement of the above technical solution, as shown in fig. 9, the swing support part 22 is mainly composed of several parts, such as a bottom plate 221, a swing support assembly 222, and a top plate 223. The base plate 221 is disposed on the floor of the workshop, and is locked in position by anchor bolts. The top plate 223 is disposed horizontally and is located right above the bottom plate 221. The pivoting support assembly 222 serves as a coupling transition between the bottom plate 221 and the top plate 223. The first special-shaped bearing plate 211 and the second special-shaped bearing plate 212 are both detachably fixed on the top disk 223 by bolts. In this manner, in the course of performing the film winding operation on the troweling tray, when the worker applies a lateral pushing force to the troweling tray, the top tray 223 freely performs a circumferential rotational movement with respect to the bottom tray 221 by being subjected to the rotational moment until the film winding operation of one stage is completed.

It is known that, according to common design knowledge, the rotary support assembly 222 may take various design structures to realize the support of the top plate 223 and ensure that the top plate 223 can freely perform circumferential rotation movement around its central axis, for example, the rotary support assembly 222 is selected as a rotary support bearing connected between the bottom plate 221 and the top plate 223. The slewing bearing is a purchased part, can bear a special bearing of comprehensive load, and can simultaneously bear larger axial and radial loads and overturning moment. However, the purchase cost of the slewing bearing is relatively high, and the market price is over 1200 yuan, which causes a large pressure for the production cost accounting. In view of this, as another modified design of the above technical solution, as shown in fig. 10, the rotation support assembly 222 preferably includes a cylinder 2221, a force-bearing shaft 2222, an upper radial angular contact bearing 2223, and a lower deep groove ball bearing 2224. The cylinder 2221 is vertically arranged and fixed to the top wall of the base plate 221 by welding. The upper angular contact radial bearing 2223 and the lower deep groove ball bearing 2224 are embedded in the cavity of the cylinder 2221, and are spaced apart by a predetermined distance in the height direction. The force-bearing shaft 2222 is inserted into the cavity of the cylinder 2221, and its freedom of displacement in the height direction is limited by the cooperation of the upper angular contact bearing 2223 and the lower deep groove ball bearing 2224, and can freely perform circumferential rotational movement around its central axis. The top end of the bearing shaft 2222 is directly contacted with the bottom wall of the top disk 223 and welded. In the process of performing the film winding operation, the worker continuously pushes the troweling plate sideways (the top plate 223 is continuously subjected to the transmission force to perform the circumferential rotation motion around the central axis thereof), the troweling plate follows the rotation, and at the same time, the plastic film released through the plastic film releasing portion 2 is wrapped and wound in the diametrical direction of the troweling plate. In this way, the implementation cost of the rotation support assembly 222 is greatly reduced and the cost is within 300 yuan on the premise of ensuring the design that the top plate 223 can freely rotate with low resistance.

It should be noted that the rotary support member 222 may also be preferably a hollow rotary platform (a built-in part) disposed between the bottom plate 221 and the top plate 223, so that when performing the film winding operation, a worker only needs to control the rotation process of the troweling plate around its own central axis, and does not need to control the rotation process in the other direction (the hollow rotary platform is used to directly control the rotation process of the top plate 223 around its own central axis), thereby further reducing the labor intensity of the worker.

As shown in fig. 3, 11, and 12, the first shaped bearing plate 211 is a sheet metal bent part, and is formed by a first horizontal section 2111, a first vertical section 2112, and a first camber section 2113 in sequence. The second special-shaped bearing plate 212 is also a sheet metal bending part, and is sequentially composed of a second horizontal section 2121, a second vertical section 2122 and a second outward-inclined section 2123. The first and second horizontal sections 2111 and 2121 are respectively provided with a first elongated waist-shaped hole 21111 and a second elongated waist-shaped hole 21211 through which the bolt freely passes. The length extension directions of the first elongated waist-shaped hole 21111 and the second elongated waist-shaped hole 21211 are consistent with the width direction of the insertion gap. Therefore, when the thickness value of the flattening disc to be wrapped is changed, a worker unscrews the bolts in advance, and then drags the first special-shaped bearing plate 211 and the second special-shaped bearing plate 212 respectively until the insertion gap value formed between the first special-shaped bearing plate 211 and the second special-shaped bearing plate 212 meets the design requirement, so that the flattening disc is kept in a small-gap contact state with the first special-shaped bearing plate 211 and the second special-shaped bearing plate 212 after being inserted, the flattening disc is kept in a vertical state all the time in the process of being wrapped with the film, and finally the strip-shaped plastic film is wound on the flattening disc correctly and regularly.

It should be noted that, due to the existence of the first camber section 2113 and the second camber section 2123, an flared passage is formed therebetween, which is favorable for guiding the insertion direction of the troweling tray, and thus, the difficulty of the worker in performing the troweling tray placement operation can be greatly reduced.

Fig. 13 shows a schematic perspective view of a plastic film releasing part in the concrete troweling tray film wrapping device of the present invention, which is mainly composed of a base 11, a straight rod 12, a limiting piece 13, and a plastic film roll 14. Wherein, the base 11 is arranged on the floor of the workshop and is positioned at one side of the packaging winding part 2, and the self position of the base can be locked by the foundation bolt. The straight rod 12 is vertically arranged and directly welded on the base 11. The limiting sheet 13 is used for limiting the axial displacement freedom degree of the plastic film roll 14, is sleeved on the straight rod 12, and is welded and fixed with the straight rod 12 into a whole. The plastic film roll 14 is sleeved on the straight rod 12, and when the plastic film roll is subjected to a pulling force from the leveling disc in the process of performing a film winding operation on the leveling disc, the plastic film roll can freely perform circumferential rotation motion around the central axis of the plastic film roll to release the strip-shaped plastic film layer by layer. Therefore, on one hand, the strip-shaped plastic film is favorably ensured to be stably and accurately released, and finally the release speed of the strip-shaped plastic film is ensured to be cooperated with the actual rotating process of the leveling disc in the film winding process; on the other hand, the plastic film releasing part 1 has a very simple design structure, which is beneficial to reducing the implementation cost.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
