Detailed Description

In order to make the technical solutions and advantages of the present invention more apparent, exemplary embodiments of the present invention are described in further detail below with reference to the accompanying drawings. It is clear that the described embodiments are only a part of the embodiments of the utility model, and not an exhaustive list of all embodiments. And the embodiments and features of the embodiments may be combined with each other without conflict.

Fig. 1 schematically shows the overall structure of a device for scraper chain assembly according to an embodiment of the utility model. As shown in fig. 1, the apparatus for assembling a scraper chain 20 of the present embodiment includes a support plate 1 and a driving assembly. Wherein the support plate 1 is a flat plate extending in the longitudinal direction for placing and supporting the scraper chain 20. The support plate 1 is provided with an operation port 2 communicating in the vertical direction. The drive assembly is used to drive the scraper chain 20 to move longitudinally relative to the support plate 1.

In use, the front end of the scraper chain 20 may be disposed at the rear end of the support plate 1, and the driving assembly drives the scraper chain 20 to move longitudinally and forward. When the position of the chain 21 which needs to be provided with the scraper 22 and the pressing strip 23 is moved to the operation opening 2, the chain can be stopped. And the pressing strip 23 is arranged on the back of the chain 21 at the operation opening 2, the scraper 22 is arranged on the front of the chain, and the bolts 24 are used for screwing, so that the scraper 22 and the pressing strip 23 clamp the chain 21, and the assembly of the scraper 22 and the pressing strip 23 is completed. It can be seen that through the device of this application, can avoid the manual work to lift the chain, improve production efficiency, especially alleviateed workman's work slightly, and then guaranteed operator's personal safety.

In a particular embodiment, the drive assembly includes a power source 3, a drive sprocket 4, a drive chain 5, a driven sprocket 6, and a stop 7. Wherein the power source 3 is used for providing power, for example, the power source 3 may be an electric motor. A speed reducer 8 is connected to an output shaft of the power source 3. The reducer 8 can drive the driving chain wheel 4 to rotate. The driving sprocket 4 is disposed at one end of the support plate 1 in the longitudinal direction. The driving chain 5 is matched with the driving chain wheel 4 and moves under the action of the driving chain wheel 4. The driven sprocket 6 is engaged with the drive chain 5, and the driven sprocket 6 is provided at the other end in the longitudinal direction of the support plate 1. The stopper 7 is fixedly provided on the drive chain 5, and the stopper 7 extends upward in a protruding manner to abut against the blade 22 of the scraper chain 20, so that the scraper chain 20 is pulled by the drive chain 5. For example, the stopper 7 may be configured in a rod shape, a plate shape, or the like. Preferably, two sets of the chain transmission mechanisms are arranged at the two transverse ends of the supporting plate 1, so as to ensure the balance of the actuating force and ensure the stable advance of the scraper chain 20.

A plurality of stoppers 7 are provided on the drive chain 5. The distance between adjacent stops 7 is equal to the distance between adjacent flights 22 of the flight chain 20. The limiting member 7 not only acts to urge the scraper chain 20 to advance, but also serves as a mounting and positioning reference for arranging the scraper 22 on the corresponding chain 21 when the limiting member 7 runs to the operation opening 2.

The pitch of the drive chain 5 is configured in a relationship of an integral multiple of the pitch of the chain 21 of the flight chain 20. By this arrangement, proper operation of the chain 21 is ensured without misalignment.

Guide grooves 9 are oppositely distributed on two sides of the support plate 1 in the transverse direction. The guide groove 9 may be a U-shaped bending plate welded to both lateral sides of the support plate. The openings of the two U-shaped bending plates are opposite. The guide groove 9 is used to guide the blade 22 of the scraper chain 20. That is, the two lateral ends of the scraper 22 extend into the guide grooves 9 on the same side, and the scraper 22 cooperates with the guide grooves 9 to guide the scraper chain 20 during the longitudinal movement of the scraper chain 20. The arrangement avoids the problem of the scraper chain 20 of jumping off or jumping over during the moving process, and ensures the running stability of the scraper chain 20.

Preferably, a rolling mechanism (not shown in the drawings) is configured on the plane of the guide groove 9 that is in contact with the blade 22 of the scraper chain 20. With this arrangement, rolling friction can be formed between the scraper 22 and the guide groove 9, and the friction force is relatively reduced, ensuring smooth movement of the scraper chain 20. At the same time, this arrangement protects the contact surfaces, and in particular the contact surfaces of the scraper 22, from wear.

A guide wheel 10 is provided at the longitudinal rear end of the support plate 1. The guide wheel 10 is configured to rotate about a laterally extending axis. In operation, the chain 21 at the rear end of the scraper chain 20 overlaps the guide wheel 10, and the rotating guide wheel 10 can support the chain 21 and reduce friction, ensuring smooth forward movement of the chain 21.

As shown in fig. 2 and 3, a guide groove 11 extending in the circumferential direction is provided on the outer wall of the guide wheel 10. That is, a circumferential groove is provided on the outer wall of the guide wheel 10 so that the diameter of both axial sides of the guide wheel 10 is larger than that of the middle portion. In use, the vertical rings 25 of the chain 21 of the scraper chain 20 are inserted into the guide grooves 11, and the lateral rings 26 of the chain 21 are overlapped on the guide wheels 10 at both axial ends of the guide grooves 11. The guide wheel 10 thus arranged defines the direction of travel of the chain 21, ensuring its straight travel, rather than its twist-like travel.

The device further comprises a leg 12 arranged below the support plate 1. The legs 12 mainly serve as a support. Thus, the number of legs 12 can be set appropriately according to various needs.

The method of assembling scraper chain 20 with the apparatus is described in detail below with reference to figures 1 to 3.

First, a first set of flights 22 and hold down plates 23 are provided on the front end of the chain 21 and the set of hold down plates 23 and flights 22 are connected together by bolts 24.

Then, the first set of squeegees 22 are set to the support plate 1 such that both lateral ends of the squeegees 22 extend into the guide grooves 9. Meanwhile, in the longitudinal direction, the squeegee 22 abuts against the stopper 7, wherein the stopper 7 is located at the longitudinal rear end of the squeegee 22. The chain 21 is readjusted so that the vertical rings 25, which are aligned with the guide wheels 10, are inserted into the guide grooves 11, and the horizontal rings 26 overlap the guide wheels 10 at both axial ends of the guide grooves 11.

Then, the power source 3 is started, and the power source 3 drives the speed reducer 8 and the driving sprocket 4 to operate, so as to drive the driving chain 5 to move. During the movement of the driving chain 5, the limiting member 7 pushes the scraper 22 to move, and then drives the whole scraper chain 20 to move. The position of the next mounting blade 22 is moved to the operation opening 2. Stopping power source 3 and ensuring scraper chain 20 does not advance any more. The set of the flights 22 and the beads 23 are assembled to the chain 21 by disposing the beads 23 on the back of the chain 21 at the operation opening 2, disposing the flights 22 on the front of the chain 21, and tightening them with the bolts 24 so that the flights 22 and the beads 23 sandwich the chain 21. The above-described actions are repeated in sequence until the assembly of all the squeegees 22 and the bead 23 is completed. At this time, the scraper chain 20 may be dropped into the receiving container from the front end of the support plate 1.

In the movement process of the scraper chain 20, the problem of the scraper chain 20 jumping or jumping in the moving process can be avoided through the guide groove 9, and the operation stability of the scraper chain 20 is ensured. The guide wheel 10 can define the running direction of the chain 21, ensure the straight running of the chain, and facilitate the subsequent assembly of the scraper 22 and the pressing plate 23.
