Description

Technical Field

[0001] The utility model relates to the technical field of punching equipment, in particular to a rubber strip punching machine. Background Art

[0002] A rubber strip punching machine is a mechanical device specially used to punch holes in rubber strip materials. Rubber strips are usually used in various sealing, fixing, protection or decoration occasions, such as door and window sealing strips, automobile sealing strips, electrical appliance sealing strips, etc. In these applications, it is sometimes necessary to punch holes in the rubber strips to meet specific installation, fixing or ventilation requirements.

[0003] In order to meet the sealing needs of different parts, sealing strips often need to be punched according to specific design requirements. Therefore, the existing mainstream strip punching machines can only perform one punching process at the same time. In addition, during the use of existing strip punching machines, a common problem is that waste is easy to accumulate. Existing strip punching machines usually adopt a mechanical punching method to punch holes in the sealing strips through the up and down movement of the tool. During the punching process, a large amount of waste is generated. If the waste is not cleaned up in time, it is easy to accumulate in various parts of the punching machine, such as around the tool, on the strip track, in the waste collection box, etc. This not only affects the normal operation of the punching machine, but may also lead to reduced production efficiency and unstable product quality.

[0004] Therefore, it is necessary to provide a new rubber strip punching machine to solve the above-mentioned technical problems. Utility Model Content

The outer diameter of the punching knife 5 is the same as the inner diameter of the knife hole 102, and there is damping between the fixed column 106 and the punching roller 101;

[0031] It should be noted that: when the first electric push rod 2 is working, the first motor 13 first pushes the locking column 6 downward, and the locking column 6 drives the punching knife 5 and the connecting rod 111 to move downward. At this time, the outer wheel 110 rotates clockwise with the connecting rod 111, and the inner wheel 107 remains stationary due to the damping between the fixed column 106 and the punching roller 101. The latch teeth 108 connected to the outer wall of the inner wheel 107 are squeezed into the multiple groups of contraction grooves equidistantly opened on the outer wall of the inner wheel 107. When the punching knife 5 completes punching, the first electric push rod 2 pulls up the locking column 6, which pulls the punching knife 5 and the connecting rod 111 upward. At this time, the outer wheel 110 rotates counterclockwise along with the connecting rod 111. The second spring 109 pushes the latching tooth 108 into the latching slot. The outer wheel 110 drives the inner wheel 107 to rotate counterclockwise through the latching tooth 108 and the latching slot. The inner wheel 107 drives the punching roller 101 to rotate counterclockwise along with the outer wheel 110. When the first electric push rod 2 completes the reset, the inner wheel 107 and the punching roller 101 have rotated exactly 60 degrees.

[0032] The working principle of the rubber strip punching machine provided by the utility model is as follows:

[0033] When punching: start the first electric push rod 2, the first electric push rod 2 first pushes the locking knife column 6 downward, the locking knife column 6 drives the punching knife 5 and the connecting rod 111 to move downward, at this time, the outer wheel 110 rotates clockwise with the connecting rod 111, and the inner wheel 107 remains stationary due to the damping between the fixed column 106 and the punching roller 101, and the locking teeth 108 connected to the outer wall of the inner wheel 107 are squeezed into the multiple groups of shrinkage grooves equidistantly opened on the outer wall of the inner wheel 107. When the punching knife 5 completes punching, the first electric push rod 2 pulls the locking knife column 6 upward, and the locking knife column 6 pulls the punching knife 5 and the connecting rod 111 to move upward. At this time, the outer wheel 110 will rotate counterclockwise with the connecting rod 111 , the second spring 109 pushes the latching tooth 108 into the slot, and the outer wheel 110 drives the inner wheel 107 to rotate counterclockwise through the engagement of the latching tooth 108 with the slot, and the inner wheel 107 drives the punching roller 101 to rotate counterclockwise along with the outer wheel 110. When the first electric push rod 2 completes the reset, the inner wheel 107 and the punching roller 101 rotate exactly sixty degrees, and the motor 13 is started. The motor 13 drives the lower traction wheel 91 to rotate counterclockwise, and the lower traction wheel 91 squeezes the rubber strip together with the upper traction wheel 95, driving the rubber strip to move in the direction of the lower chute 8. After the rubber strip moves a suitable distance, the motor 13 stops rotating, and the first electric push rod 2 starts working, and the above steps are repeated;

[0034] When cutting the rubber strip: After the rubber strip is punched, the motor 13 drives the lower traction wheel 91 to move the rubber strip to the appropriate position in the direction of the lower feeding chute 8. The second electric push rod 3 is started and pushes the cutter 7 downward. After the rubber strip is cut, the second electric push rod 3 pulls the cutter 7 to reset. The cut rubber strip slides along the feeding chute 8 into the collection basket.

[0035] Automatic collection of waste: When the punching knife 5 punches a hole, the third spring 51 and the push block 52 are squeezed into the punching knife 5 due to the extrusion of the rubber strip. When the punching knife 5 completes the punching, the punching knife 5 is still inserted into the knife hole 102 of the punching roller 101. The third spring 51 pushes the push block 52 to push the waste into the punching roller 101. As the punching continues, the punching roller 101 rotates sixty degrees multiple times. When the hole with waste in the punching roller 101 is facing directly downward, the push rod slidingly linked in the punching roller 101 is squeezed out by the cam 105, and the push rod squeezes the waste into the waste chute 11. When the punching roller 101 rotates again, the first spring 104 pushes the push rod inward to complete the reset.

[0036] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
