As shown in fig. 1-4, the feeding mechanism includes a slide rail 1, a feeding assembly 2, a cutting assembly 3, and a connecting assembly 4. The slide rail 1 extends in a first direction (X direction in fig. 1 and 3). The feeding assembly 2 comprises a first support 21 and a plurality of material racks 22 arranged on the first support 21 at intervals along a first direction, the first support 21 is arranged on the sliding rail 1 in a sliding mode, the material racks 22 are provided with rotating discs 23 in a rotating mode, the strip-shaped raw materials 100 are wound on the rotating discs 23, and the strip-shaped raw materials 100 of one material rack 22 are connected to a using end. The cutting assembly 3 includes a second bracket 31 and a first cutting member 32, the first cutting member 32 is slidably disposed on the second bracket 31 along a second direction (Y direction in fig. 1 and 3), the first cutting member 32 can cut off the strip-shaped raw material 100 connected to the using end, so that the strip-shaped raw material 100 is divided into a waste section and a section 101 to be connected, and the second direction is perpendicular to the first direction. The connecting assembly 4 includes a first ejector 41, the first ejector 41 being slidable in the second direction to push the strip material 100 of the other stack 22 toward the section to be connected 101 and connect the two.

In the feeding mechanism, as shown in fig. 2, the first cutting member 32 can slide along the second direction to cut off the strip-shaped raw material 100 of the to-be-used material rack 22, so that the to-be-used strip-shaped raw material 100 is divided into a waste material segment and a to-be-connected segment 101, wherein the waste material segment is wound on the turntable 23, and the to-be-connected segment 101 is connected with the using end. As shown in fig. 4, the first carriage 21 can slide along the slide rail 1 to switch the use of different stacks 22, and the first ejector 41 can eject the strip-shaped raw material 100 of a new stack 22 into abutment with the section to be connected 101 and connect the new strip-shaped raw material 100 and the section to be connected 101. Specifically, if the strip-shaped raw material 100 itself is not sticky, the new strip-shaped raw material 100 is stuck with glue, and when the new strip-shaped raw material 100 is pushed to the section to be connected 101 by the first pushing member 41, the glue abuts against the section to be connected 101 and fixes the new strip-shaped raw material 100 to the section to be connected 101 in a gluing manner. If the strip-shaped material 100 itself has tackiness, the adhesive may be used without providing a glue.

When the strip material 100 of one stack 22 is used up, the first cutting member 32 of the cutting assembly 3 slides in the second direction to approach the strip material 100 and cut the strip material 100, so that the strip material 100 is divided into the waste segment and the segment to be connected 101. Then, the operator slides the first support 21 to move another rack 22 with sufficient strip-shaped raw material 100 to the section to be connected 101, and the operator slides the first ejector 41 in the second direction to make the first ejector 41 push the strip-shaped raw material 100 of the new rack 22 to the section to be connected 101 and connect the two, thereby completing the loading.

Fig. 5 is a front view of the first cutter 32 after the strip-shaped raw material 100 is cut. As shown in fig. 4 and 5, the cutting assembly 3 further includes a pressing member 33, the pressing member 33 is slidably disposed on the second bracket 31 along the second direction, the second bracket 31 is provided with a pressing portion 311, and the pressing member 33 can press the segment 101 to be connected against the pressing portion 311. The used tape-like raw material 100 is in an uncontrolled state when it is cut by the first cutting member 32, so that the to-be-connected segment 101 cannot be bonded to a new tape-like raw material 100. The pressing member 33 can press the strip-shaped raw material 100 against the pressing portion 311 before the used strip-shaped raw material 100 is cut, so that the to-be-connected section 101 formed after the strip-shaped raw material 100 is cut can be in a stable state, and the first ejector 41 can be ensured to be in contact with and bonded to the to-be-connected section 101 when pushing a new strip-shaped raw material 100. Wherein the pressing member 33 is located below the first cutting member 32 so as to press against the segment to be connected 101.

Preferably, the abutting portion 311 is provided with a cutting portion 312 at a side facing the first cutting member 32. The cutting part 312 can form opposite cutting force with the first cutting part 32, effectively complete the cutting of the strip-shaped raw material 100 to be used up, and prevent the first cutting part 32 from being incapable of cutting off the strip-shaped raw material 100 to cause the need of manual intervention, causing shutdown and affecting the production efficiency.

It will be appreciated that the new strip-like material 100 is also in an uncontrolled state before being attached to the section 101 to be attached, and is difficult to be accurately pushed by the first ejector 41 into contact with the section 101 to be attached. To solve this problem, the lower end of the rack 22 is provided with a fastening member 221, and when the strip material 100 is not connected to the use end, the strip material 100 is fixedly connected to the fastening member 221. The fastener 221 can fix one end of the strip-shaped raw material 100 in a state where the strip-shaped raw material 100 is straightened so that the position of the strip-shaped raw material 100 is kept unchanged. When the first ejector 41 slides in the second direction, it is certainly possible to contact the strip-shaped raw material 100 and eject the strip-shaped raw material 100 into contact with and connected to the section to be connected 101.

Since a new strip-shaped material 100 is connected to the section to be connected 101 from the middle portion, one end of the strip-shaped material 100 is still fixed by the fastening member 221. In order to enable the strip-shaped raw material 100 to be detached from the fastening member 221 and minimize the surplus portion of the joint, the joint assembly 4 further includes a second cutter 44, and the second cutter 44 is slidable in the second direction and cuts the strip-shaped raw material 100 after the first ejector 41 ejects the strip-shaped raw material 100 to bond the strip-shaped raw material 100 to the segment 101 to be joined.

In order to ensure that the new strip-shaped raw material 100 can be cut by the second cutting member 44, the connecting assembly further comprises an auxiliary cutting member 45, the auxiliary cutting member 45 and the second cutting member 44 are respectively arranged at two sides of the new strip-shaped raw material 100, and after the first ejector 41 ejects the strip-shaped raw material 100 to bond the strip-shaped raw material 100 with the section to be connected 101, the second cutting member 44 is matched with the auxiliary cutting member 45 to cut the strip-shaped raw material 100. Specifically, the auxiliary cutter 45 is provided to the second bracket 31 for convenience of arrangement.

Preferably, the cutting assembly 3 further comprises a second ejector 34, the second ejector 34 being slidable in the second direction to push the section to be connected 101 towards the strip-like raw material 100 pushed by the first ejector 41. The first ejector 41 pushes the strip-shaped raw material 100, and the second ejector 34 pushes the section 101 to be connected, so that the strip-shaped raw material 100 and the section 101 to be connected are close to each other and bonded, and the strip-shaped raw material 100 can be prevented from being broken due to being pushed by the first ejector 41 too far.

As shown in fig. 2 and 4, the second ejector 34 is provided with a fixing groove 341, and the first ejector 41 can be inserted into the fixing groove 341. When the second ejector 34 ejects the section to be connected 101, the section to be connected 101 enters the fixing groove 341 to prevent the section to be connected 101 from being deviated to be unable to be connected to the strip-shaped raw material 100. And the first ejector 41 can enter the fixing groove 341, that is, the first ejector 41 can eject the strip-shaped raw material 100, so that the strip-shaped raw material 100 enters the fixing groove 341 and is completely bonded with the section to be connected 101 in the fixing groove 341, and the bonding accuracy is ensured.

In other embodiments, the first ejector 41 is opened with a fixing groove 341, and the second ejector 34 can be inserted into the fixing groove 341. At this time, the first ejector 41 is first slid in the second direction to allow a new strip-shaped raw material 100 to enter the fixing groove 341, and then the second ejector 34 pushes the section to be connected 101 into the fixing groove 341 and bonds the strip-shaped raw material 100 to the section to be connected 101, and then the second cutter 44 is moved to cut the strip-shaped raw material 100.

Preferably, the connecting assembly 4 further includes a sliding block 42 and an elastic member 43, the sliding block 42 can slide along the second direction, the first pushing member 41 is connected with the sliding block 42 in a sliding manner, and two ends of the elastic member 43 respectively abut against the first pushing member 41 and the sliding block 42. The slide block 42 is provided to enable the first ejector 41 to compress the elastic member 43 when the strip-shaped raw material 100 is pressed against and bonded to the segment 101 to be connected, enable the second cutting member 44 to continue moving to cut off a new strip-shaped raw material 100, and enable the pressing force of the first ejector 41 against the strip-shaped raw material 100 and the segment 101 to be connected to gradually rise, thereby preventing the strip-shaped raw material 100 and the segment 101 to be connected from being damaged.

Specifically, the second cutting member 44 is fixedly disposed on the sliding block 42, and the second cutting member 44 and the first ejector member 41 move synchronously, so that a power source can be reduced, the control difficulty is reduced, and the cost is reduced. And the first ejector 41 contacts the strip-shaped raw material 100 before the second cutting member 44, so that the second cutting member 44 cuts the strip-shaped raw material 100 when the first ejector 41 and the second ejector 34 press the strip-shaped raw material 100 and the section 101 to be connected tightly, and the first ejector 41 compresses the elastic member 43.

Similarly, the pressing member 33 and the first cutting member 32 also move synchronously, and the pressing member 33 contacts the strip-shaped raw material 100 to be used up before the first cutting member 32, so as to ensure that the pressing member 33 presses the strip-shaped raw material 100 against the stopping portion 311 when the first cutting member 32 cuts off the strip-shaped raw material 100, thereby preventing the segment to be connected 101 from being uncontrolled and being unable to be connected with a new strip-shaped raw material 100. Specifically, the front end of the pressing member 33 is provided with a polyurethane layer, and the polyurethane layer can be compressed, so that the pressing force of the pressing member 33 on the section 101 to be connected gradually increases, and the first cutting member 32 can cut off the running-out strip-shaped raw material 100 in the process of compressing the polyurethane layer.

Further, the feeding mechanism also comprises a moving assembly 5. As shown in fig. 1 and fig. 3, the moving assembly 5 includes a screw rod 51 and a driving member 52, the screw rod 51 is rotatably disposed on the slide rail 1 and is in threaded connection with the first bracket 21, and the driving member 52 is fixedly disposed on the slide rail 1 and is in transmission connection with the screw rod 51. When the running strip material 100 is cut by the first cutter 32, the driving member 52 drives the screw 51 to rotate, so that the first frame 21 moves in the first direction, so that the rack 22 containing the new strip material 100 can be moved to the section 101 to be connected.

Preferably, the stack 22 is provided with a plurality of tension wheels 222, and the tension wheels 222 are used for tensioning the strip-shaped raw material 100. Since the strip-shaped material 100 is soft, the strip-shaped material 100 is tensioned by the tension roller 222, and thus, the shape and position of the strip-shaped material 100 can be prevented from being changed, the strip-shaped material 100 can be cut and connected easily, and the probability of connection failure can be reduced.
