Detailed Description

The following specific examples are given by way of illustration only and not by way of limitation, and it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made in the examples without inventive faculty, and yet still be protected by the scope of the claims.

Embodiment 1, as shown in fig. 1 and 2, a fan framework shaper comprises a frame 1, wherein a conveying line 2 for conveying a fan framework is installed on the frame 1, the conveying line 2 is preferably a forward linear conveying device for facilitating the carrying of the fan framework and the bending in the scheme, the fan framework is placed on the conveying line to be flat, preferably to be in front and in back, namely the whole fan framework is laid horizontally and is placed along the front and back direction, the conveying line 2 is provided with an outlet pressing device 3 for pressing against the upper surface of the fan framework by an outlet 20, the lower surface of the conveying line is contacted with the conveying line, in general, the fan framework mainly serves as a large framework, and the small fan framework can be used, but the small fan framework does not need to be bent, so the embodiment mainly refers to the bending of the large framework, if the large framework is provided, the upper surface of the fan framework can be the front surface, the folding fan can also be the reverse side, wherein the front side refers to the surface of the large bone close to the outer side of the folding fan after the folding fan is made, and the reverse side refers to the surface for bonding the folding paper. The structure ensures the smooth conveying of the straight fan ribs. If bending is needed, the following structural design is needed: and a direction-changing shaping device 4 for changing the advancing direction of the front end of the fan rib is arranged in front of the outlet 20. The purpose of the design is to enable the fan ribs to be conveyed out after being processed and molded in the previous procedure, and then the bending process can be directly completed in the conveying process, the efficiency can be greatly improved, on one hand, the head advancing direction of the fan ribs which are originally conveyed according to the original direction needs to be changed through the direction-changing shaping device 4, on the other hand, a section, in which one section of the fan ribs are bent, between the outlet pressing device 3 and the direction-changing shaping device 4 can be formed because the outlet pressing device 3 can be pressed against the rest part of the fan ribs which are still in the conveying line, and the section is continuously bent from the head to the tail of the fan ribs in the conveying process until the tail of the fan ribs leaves the outlet pressing device 3, the whole bending operation can be finished, and in order to ensure the bending effect of the operation, the distance between two nearest force application points of the outlet pressing device 3 and the direction-changing shaping device 4 to the fan ribs is smaller than the length of the fan ribs, for example, a value of 10-15cm is set for this distance, whereas the length of a typical fan bone is 20-30cm, thus ensuring enough time to enable the fan ribs to be in the bending state and to be continuously bent from the head to the tail, because the thickness of the fan ribs is not too thick and is basically controlled within 5mm, the fan ribs are relatively easy to bend, the duration of this bending can be not too long, basically 2-3 seconds is sufficient, therefore, the speed of the conveying line is controlled to be 5cm/s, if the design of the conveying line, the outlet abutting device 3 and the direction-changing shaping device 4 is better, more than 2 fan ribs can be placed side by side in the same front and back advancing interval of the conveying line, therefore, a plurality of fan ribs can be conveyed and bent at the same time in the same time period, and the efficiency can be greatly improved.

How to further improve the effect of the above solution and better strengthen the more detailed structural design of the bending in this way is very helpful to better realize the bending of the fan ribs.

The conveying line 2 should have a bearing surface 200 for supporting the fan ribs, and the bearing surface 200 is preferably a rigid plane. On one hand, the fan framework is kept in a relatively flat state in the conveying process on the conveying line before being bent, on the other hand, the fan framework is subjected to the force for changing the direction of the direction-changing shaping device 4 and bending the fan framework in the bending process, the rear end part of each instant bending section of the fan framework is guaranteed to be better supported between the outlet supporting and pressing device 3 and the rigid surface, and the stability of a rear side force application point is kept.

In order to realize the design of the rigid surface, the conveyor line 2 may be configured to have a structure including a plurality of steel plates a arranged at intervals in a front-back direction, so that the upper surfaces of all the steel plates a form the bearing surface 200, that is, the bearing surface 200 is formed by discrete surfaces of the upper surfaces of the plurality of steel plates a, but the upper surfaces of the dry steel plates a should be designed to be as flat as possible and located at the same height, so as to meet the requirement of more refined production and processing. The steel plates a can be fixedly arranged on the frame.

In addition, the bearing surface 200 is preferably a smooth surface, which facilitates smooth forward conveying of the fan ribs, the conveying line 2 is further provided with a plurality of sets of upper driving wheels b1 which are installed on the rack 1 and used for pressing the upper surfaces of the fan ribs and lower driving wheels b2 which are installed on the rack 1 and used for pressing the lower surfaces of the fan ribs, the mode is a relatively stable and effective conveying mode, and of course, if only the upper driving wheels b1 are adopted, the lower parts of the fan ribs are smoothly supported by the bearing surface 200, and the upper driving wheels b1 can drive the fan ribs to move forward under the condition that the upper surfaces of the fan ribs are pressed by the upper driving wheels b1 to generate friction force and can rotate independently.

If two wheel bodies of the upper driving wheel b1 and the lower driving wheel b2 are adopted, it is preferable that the upper driving wheel b1 and the lower driving wheel b2 are both rubber wheels, and of course, at least one of the wheels is a driving wheel, i.e., can be driven by a motor to operate autonomously to provide driving force, and the fan ribs are driven to advance by friction force generated by the upper and lower abutting. The requirement on the position is high, and the method can be well realized by adopting the following method: each set of upper driving wheel b1 and lower driving wheel b2 can be arranged at the front-rear interval between two adjacent steel plates a, each set of upper driving wheel b1 and lower driving wheel b2 are arranged oppositely at an upper-lower interval to form a pressing channel b12 for the forward movement of the fan framework, the bottom of the upper driving wheel b1 and the top of the lower driving wheel b2 should be respectively abutted against the upper and lower surfaces of the fan framework and generate a certain pressing force, since the upper driving wheel b1 and the lower driving wheel b2 both use rubber wheels, of course, their outer rings are rubber rings, the thickness of the rubber rings is preferably larger than the thickness of the fan framework, for example, 3cm thick rubber rings can be used, and the upper driving wheel b1 and the lower driving wheel b2 have a certain deformability, so the upper-lower interval of the pressing channel b12 at the upper-lower interval between the upper driving wheel b1 and the lower driving wheel b2 should be slightly smaller than the thickness of the fan framework, and the difference is preferably controlled within 2mm, thus, the fan ribs can be rolled and pushed up and down to be conveyed forwards. Of course, the axial direction of the upper driving wheel b1 and the lower driving wheel b2 is perpendicular to the forward conveying direction, so that the wheel surface can advance forward with the fan ribs. The distance between the adjacent extrusion channels b12 formed by the two adjacent sets of upper driving wheels b1 and lower driving wheels b2 should be less than the length of the fan ribs, so that the fan ribs can be engaged and engaged at both head and tail positions better to advance forward, or the distance between the adjacent extrusion channels b12 is equal to or slightly larger than the length of the fan ribs, but the slightly larger condition should be controlled within 2cm larger than the length of the fan ribs, because the fan ribs can be fed to the front set of upper driving wheels b1 and lower driving wheels b2 by inertia and can be conveyed continuously. The structures can well convey the fan ribs. The upper driving wheel b1 and the lower driving wheel b2 are preferably adjustable in height up and down, the shaft sleeves sleeved on the wheel shafts of the upper driving wheel b1 and the lower driving wheel b2 can be installed on the frame through the existing lifting mechanism which can be adjusted up and down such as a screw rod and an air cylinder, in addition, the height of the highest position of the lower driving wheel b2 is kept consistent with the height of the bearing surface formed by the steel plate as much as possible, and therefore the fan ribs can always keep straight and stably move on the steel plate when lying.

Next, some specific explanations are made on the direction-changing shaping device 4, where the direction-changing shaping device 4 includes a direction-changing guide wheel 5 located in front of the outlet 20, and the direction-changing guide wheel 5 may also be a rubber wheel, and is also installed on the rack, or is separately located in front of the rack and is set through another support frame, but there is a difference that the design of the position of the direction-changing guide wheel 5 is required: 1. the lowest position of the direction-changing guide wheel 5 is lower than the height of the upper surface of the fan ribs conveyed from the outlet 20; 2. the highest position of the direction-changing guide wheel 5 is higher than the height of the lower surface of the fan ribs conveyed from the outlet 20. It is generally preferable to adopt two solutions, as exemplified in the solution 1, in which the axial direction of the direction-changing guide wheel 5 is perpendicular to the forward conveying direction of the conveying line, and the difference between the lowest position of the direction-changing guide wheel 5 and the height of the upper surface of the fan frame conveyed from the outlet 20 is preferably controlled to be between 1cm and 5cm, and the applicant suggests that it is easy to operate and achieve, and good results are obtained by taking a slightly smaller difference, for example 2cm, that is, the lowest position of the direction-changing guide wheel 5 is 2cm lower than the height of the upper surface of the fan frame conveyed from the outlet 20, where the fan frame is a fan frame which is conveyed straight forward and has not yet been bent, and if the difference is 2cm, the diameter of the direction-changing guide wheel 5 is preferably more than 3 times the difference, so that the diameter of the direction-changing guide wheel 5 can be selected to be 10cm, the contact part for guiding the fan ribs by the turning guide wheel 5 is the position close to the lower half part of the turning guide wheel 5 and below, the position can better guide the head of the fan ribs to be turned obliquely downwards and meanwhile is matched with the outlet abutting device 3 to continuously bend the fan ribs, the tail of the fan ribs is known to be separated from the outlet abutting device 3, the bending is finished, and the fan ribs are also guided to the inlet of the next procedure or the area for collecting the fan ribs by the turning guide wheel 5. Here, it is important that the height of the upper surface of the fan frame delivered from the outlet 20 to be bent is required to be lower than the height of the center of the direction-changing guide wheel 5, that is, the lower half of the direction-changing guide wheel 5, which is a position between the center of the direction-changing guide wheel 5 and the lowest position of the direction-changing guide wheel 5, and when the height difference between the lowest position of the direction-changing guide wheel 5 and the height of the upper surface of the fan frame delivered from the outlet 20 is determined, the entire diameter of the direction-changing guide wheel 5 determines the height of the upper surface of the fan frame delivered from the outlet 20 to be the position corresponding to the direction-changing guide wheel 5, the larger the diameter of the direction-changing guide wheel 5 is, so that the height of the upper surface of the fan frame is relatively close to the lower position of the direction-changing guide wheel 5, and the head of the direction-changing guide wheel 5 collides with each other to cause less damage, the protection to the structures of the fan ribs and the turning guide wheels is realized. The turning guide wheel 5 mentioned earlier can also adopt the rubber wheel, then its outer lane is the rubber circle too, and the thickness of rubber circle is preferred to be greater than the difference of the lowest position of turning guide wheel 5 and is less than the upper surface place height of the fan bone that the exit 20 was sent and is come, if the difference is aforementioned 2cm, then the thickness of rubber circle is best to exceed 2cm, because, the interior wheel body of turning guide wheel 5, or the interior wheel body of this application other wheel bodies all will adopt the steel wheel generally, the thickness promotion of outer lane rubber can cushion a lot of impulsives force, reduces the rigid collision influence.

In the above-described mode 1, the fan ribs can be bent in a downward oblique direction and conveyed. The 2 nd solution may be configured to be a structure which is a mirror image of the 1 st solution from top to bottom, that is, the fan ribs are bent in an oblique upward direction and are conveyed. Following the alternative 1, furthermore, the direction-changing shaping device 4 further comprises at least one shape-changing auxiliary wheel 6 which is matched with the direction-changing guide wheel 5 and is used for conveying the fan ribs forwards and downwards. After the fan ribs are bent, it is preferable to further maintain a segment of arc shape, so that the bending operation is continued, and such bending effect is better, so a further preferable mode is adopted, for example, in the case of adopting 1 shape-retaining auxiliary wheel 6, as mentioned above, the turning guide wheel 5 guides and bends the upper surface of the fan ribs through a height drop, so that the part of the fan ribs pressed and contacted and guided by the turning guide wheel 5 at this time has a certain curvature, i.e. presents an arc shape, and advances forward along the front lower part, in order to maintain the stability of the curvature of the fan ribs, the shape-retaining auxiliary wheel 6 can be arranged at the front lower position of the turning guide wheel 5, the shape-retaining auxiliary wheel 6 abuts against and guides the bent upper surface of the coming fan ribs, and the fan ribs actually advance forward lower part in an arc shape at this time, a lower auxiliary wheel 66 which is matched with the shape-preserving auxiliary wheel 6 and is arranged at intervals can be arranged at the oblique rear part of the shape-preserving auxiliary wheel 6, a passage with an inlet and outlet position along the oblique front and lower part is formed between the lower auxiliary wheel 66 and the shape-preserving auxiliary wheel 6 so as to be convenient for maintaining the arc state after the fan framework is bent, in addition, the lower auxiliary wheel 66 acts on the lower side surface of the fan framework and has supporting force, namely, when the fan framework is bent, the tail part is separated from the outlet abutting device 3 and cannot fall down immediately, and the fan framework can be conveyed to a destination through the passage between the lower auxiliary wheel 66 and the shape-preserving auxiliary wheel 6 and the front and lower part. The passage of the lower auxiliary wheel 66 and the shape-retaining auxiliary wheel 6 is preferably positioned such that after the head of the fan ribs has entered, a part of the tail is pressed downward by the exit pressing device 3, which is advantageous in that, in a simple manner, the overall length of the fan ribs is preferably greater than the length of the path between the exit pressing device 3 and the lower auxiliary wheel 66 and the shape-retaining auxiliary wheel 6 for the fan ribs to travel, so that the fan ribs are sufficiently bent. The lower auxiliary wheel 66 and the conformal auxiliary wheel 6 may be rubber wheels and have axial directions perpendicular to the forward and backward traveling direction. The direction-changing guide wheel 5, the lower auxiliary wheel 66 and the shape-keeping auxiliary wheel 6 can be connected with a motor to form a driving wheel, but the linear speed of the speed matching is kept consistent as much as possible, so that the fan ribs stably move.

Further, the specific design of the outlet pressing device 3: the outlet pressing means 3 may comprise at least one pressing wheel 30 capable of pressing on the upper surface of the fan ribs, said pressing wheel 30 may also be a rubber wheel. Here, two ways are provided for the design of the cooperation between the outlet pressing device 3 and the conveyor line: 1. the most front end of the conveying line is a steel plate a, the front edge of the steel plate is an outlet, the pressing wheel 30 is arranged above the most front steel plate and close to the position of the front edge outlet, a space for the fan ribs to pass through is formed between the pressing wheel 30 and the steel plate, the pressing wheel 30 can be installed on the rack and is kept fixed in the vertical position during operation, the pressing wheel can effectively abut against the moving fan ribs and can be bent subsequently, the pressing wheel 30 can be designed into a driving wheel, meanwhile, the upper part and the lower part can be adjusted through the existing lifting mechanism, for example, the pressing wheel is installed on the rack through a lead screw or an air cylinder, the vertical position is adjusted when equipment does not allow to meet the requirement that the fan ribs with different thicknesses are operated, and the pressing wheel is locked after being adjusted to the required position; 2. a set of upper driving wheel b1 and lower driving wheel b2 is further provided at the front side of the steel plate a at the foremost end of the conveyor line, and the structural design of the set of upper driving wheel b1 and lower driving wheel b2 can be referred to the above scheme, and the set of upper driving wheel b1 is used as the pressing wheel 30.

In order to better improve the efficiency, the following design can be made: and a polishing wheel 7 which is arranged on the frame 1 and is used for abutting against the upper surface of the fan framework and polishing the upper surface of the fan framework is arranged above the steel plate a, namely the upper surface of the fan framework is polished in the process of conveying the fan framework to be used as the front surface of the outer side of the folded fan, so that the process of beautifying such as polishing is carried out, and the polishing wheel 7 can be arranged on the frame in a vertically adjustable manner through the conventional lifting mechanism.

Further, the polishing wheel 7 may be a wax polishing wheel.

Still further, the bottom of the steel plate a is mounted on the frame 1 through a heat insulation plate 8. What this relates to is exactly the problem of energy-conservation, and can promote the effect of bending better, because there is the design of throwing aureola, it can all produce the friction with fan bone and steel sheet at the polishing in-process actually, can produce a lot of heat energy, therefore, fan bone has in fact just obtained frictional heating, be favorable to subsequent bending very much, improve its toughness, fiber fracture, burr scheduling problem after just can not very appear bending, but because the steel sheet can accumulate a lot of heats in continuous operation, this part heat can be better for fan bone heat conduction heating in the lower part, further promote the degree of consistency of heating in order to promote fan bone quality, the design of heat insulating board is to reduce the steel sheet and to the external heat transfer, utilize in the processing preparation of fan bone as far as possible. More preferably, the upper surface of the heat insulation plate 8 is provided with an insertion installation groove 80 into which the lower half portion of the steel plate a is inserted, so as to further improve the heat insulation performance.

In the course of the foregoing, it is mentioned that there is actually a certain collision between the direction-changing guide wheel 5 and the fan ribs, because of the aforementioned problem of height difference, and in order to better solve this problem and also better perform the bending operation, the applicant has proposed the following new design: the mechanism of the scheme is that when a fan rib comes, the bending wheel 9 extends downwards to abut against the upper surface of the fan rib and continues to extend downwards to bend by about 1cm, the bending process is controlled to be completed within 0.5 second as much as possible, then the fan framework is slowly retracted or retracted immediately after the head of the fan framework touches the turning guide wheel 5, and the bending process is a bending and pre-shaping process, so that the fan framework can be bent at a section in advance, the continuous process of bending and conveying the fan framework by the turning guide wheel 5 can be conveniently entered, the damage caused by collision during turning and bending is reduced, and the progressive bending of the fan framework is facilitated. The bending wheel 9 may of course also be a rubber wheel. In addition, the expansion device c can be controlled through the existing automatic control equipment, an induction device used for being matched with the expansion device c to use can be arranged on the rack 1, the induction device can adopt an infrared sensor and the like, when a fan rib comes, the induction device induces the fan rib and feeds the fan rib back to the automatic control equipment, then the automatic control equipment controls the expansion device c to extend downwards and retract, and the controllability of the pre-bending operation is higher. The fan ribs of the blank can be placed in the inlet of the conveying line by using a mechanical arm, for example, the fan ribs can be placed in the inlet of the conveying line by using the mechanical arm and pushed forwards to a place with a driving wheel, so that the fan ribs can be rolled in to move forwards.

In order to effectively form a production line on the rack, the mechanical structures should be arranged on the same side of the rack, for example, the conveying line, the outlet abutting device 3, the turning and shaping device 4, the shape-retaining auxiliary wheel 6 and the like are arranged on the left side of the rack to form a set of left production line, of course, the motor and other structures can be arranged on the rack or on the outer side, and of course, the whole set of equipment can be arranged on the right side to form the production line, so that the production efficiency can be improved to a greater extent.
