DETAILED DESCRIPTION

[0026] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0027] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, upper end, lower end, top, bottom...) are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the accompanying drawings).

Figure 3-7As shown, the feed box 2 includes a box body 21, and a storage chamber 22 and a waiting chamber 23 for storing rolls are formed in the box body 21. The storage chamber 22 and the waiting chamber 23 are connected, and a material dividing module 24 is provided at the connection between the two, and the rolls are transported from the storage chamber 22 to the waiting chamber 23 one by one through the material dividing module 24; a control module 25 is provided at the cavity opening of the waiting chamber 23, and the control module 25 controls the rolls to be transported one by one from the cavity opening of the waiting chamber 23 to the limiting groove 11.

[0029] For further information, see Figure 2 As shown, a blocking block 12 is provided at one end of the limiting groove 11, and the blocking block 12 blocks the reel placed in the limiting groove 11 to prevent the reel from sliding in the limiting groove 11 when the inflatable shaft penetrates the reel.

[0030] For further information, see Figure 3 and Figure 5 As shown, the bottom surfaces of the material storage chamber 22 and the material waiting chamber 23 are both inclined surfaces; by setting the bottom surface of the material storage chamber 22 as an inclined surface, it is beneficial for the rolls stored in the material storage chamber 22 to converge to the connecting point between the material storage chamber 22 and the material waiting chamber 23; by setting the bottom surface of the material waiting chamber 23 as an inclined surface, the rolls can be output from the material waiting chamber 23 in a rolling manner, wherein, in this embodiment, the bottom surface of the material waiting chamber 23 extends outward from the cavity mouth of the material waiting chamber 23 and is as close to the limiting groove 11 as possible.

[0031] Further, see Figure Figure 3 and Figure 8As shown, the material distribution module 24 includes a material distribution wheel 241 rotatably arranged at the connection between the material storage chamber 22 and the material waiting chamber 23, one end of the material distribution wheel 241 is connected to a driving motor 243 through a synchronous pulley assembly 242, and the driving motor 243 is fixed on the workbench 1; wherein, in this embodiment, six groups of material distribution grooves 2411 are axially opened on the outer surface of the material distribution wheel 241, and the material distribution grooves 2411 are evenly distributed on the outer surface of the material distribution wheel 241. When in use, the reels are transported one by one from the material storage chamber 22 to the material waiting chamber 23 through the material distribution grooves 2411. Here, it needs to be explained The number of groups of the above-mentioned material distribution troughs 2411 is only one implementation method and is not intended to limit the scope of the present application. In actual settings, more or less groups may be provided as long as the requirements are met. In addition, in the present embodiment, the synchronous pulley assembly 242 is composed of a first synchronous wheel 2421, a second synchronous wheel 2422 and a synchronous belt 2423. During installation, the first synchronous wheel 2421 is sleeved on one end of the material distribution wheel 241, the second synchronous wheel 2422 is sleeved on the output shaft of the driving motor 243, and the synchronous belt 2423 is provided between the first synchronous wheel 2421 and the second synchronous wheel 2422.

[0032] For further information, see Figure 5-6 As shown, the control module 25 includes a cylinder A251 and a cylinder B252, and the cylinder A251 and the cylinder B252 are fixed on the workbench 1 through corresponding support seats, and a blocking plate 253 is arranged at the front end of the output shaft of the cylinder A251 and the cylinder B252; during operation, the cylinder A251 and the cylinder B252 can respectively drive the blocking plate 253 arranged thereon to move up and down at the cavity mouth of the waiting cavity 23, so as to block and limit the roll in the waiting cavity 23, so as to realize intermittent supply of the roll to the limiting groove 11 through the control module 25; wherein, in this embodiment, the cylinder A251 and the cylinder B252 both adopt double-rod cylinders.

[0033] For further information, see Figure 7 As shown, the material waiting chamber 23 is provided with a first opposing photoelectric sensor 3 and a second opposing photoelectric sensor 4. During operation, when no roll is detected between the first opposing photoelectric sensors 3, the material dividing module 24 is started to convey the roll in the storage chamber 22 into the material waiting chamber 23, and when a roll is detected between the second opposing photoelectric sensors 4, the material dividing module 24 stops running and stops conveying the roll into the material waiting chamber 23, thereby realizing intermittent conveying of the roll into the material waiting chamber 23; a third opposing photoelectric sensor 5 is provided at the limit groove 11. During operation, when no roll is detected between the third opposing photoelectric sensors 5, the control module 25 is controlled to operate.

[0034] The working principle of the utility model is as follows:

[0035] Before operation, a sufficient amount of coils is placed in the storage chamber 22, and the material distribution module 24 is started to input the coils into the waiting chamber 23 one by one. Figure 3 As shown, at this time, the blocking sheet 253 blocks the two groups of rolls adjacent to the opening of the material waiting chamber 23.

[0036] During operation, when the third opposing photoelectric sensor 5 detects that there is no roll, the cylinder A251 drives the blocking piece 253 provided thereon to move downward, and the roll rolls out of the waiting chamber 23 and enters the limiting groove 11. At this time, the third opposing photoelectric sensor 5 detects that there is a roll, and the cylinder A251 drives the blocking piece 253 provided thereon to move upward and reset, while the cylinder B252 drives the blocking piece 253 provided thereon to move downward, so that the remaining rolls in the waiting chamber 23 roll downstream and are blocked by the blocking piece 253 provided on the cylinder A251. Then, the cylinder B252 drives the blocking piece 253 provided thereon to move upward and reset, thereby completing the feeding into the limiting groove 11.

[0037] Among them, after the reel is conveyed into the limiting groove 11, when the inflatable shaft is installed in the reel, the reel slides in the limiting groove 11 and is blocked and limited by the blocking block 12, so that the inflatable shaft can be quickly installed.

[0038] In addition, during the process of feeding materials to the limiting groove 11, when no roll is detected between the first opposing photoelectric sensors 3 in the waiting chamber 23, the material dividing module 24 is started to transport the roll in the storage chamber 22 to the waiting chamber 23, and during the transportation process, when a roll is detected between the second opposing photoelectric sensors 4, the material dividing module 24 stops running.

[0039] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
