[0001] This invention relates to the field of hot stamping on red envelopes, specifically a paper feeding device for a hot stamping machine used in the production of red envelopes. Background Technology

[0002] After the red envelope paper is formed, the designed pattern needs to be hot-stamped on its outer surface. Usually, a hot stamping machine is used to hot stamp each red envelope individually. During operation, the red envelope is first placed under the hot stamping part of the hot stamping machine, and then the hot stamping machine is started to drive the hot stamping part to move down and hot stamp the red envelope. After hot stamping is completed, the hot stamping machine drives the hot stamping part to move up and then removes the hot stamped red envelope. This operation is repeated. However, this hot stamping method has low production efficiency and is unsafe. In view of this, we propose a paper feeding device for hot stamping machines used in red envelope production.

[0035] Working principle and advantages of this invention: The paper feeding device for hot stamping machines used in red envelope production operates as follows:

[0036] like Figure 1 and Figure 2 As shown, in the hot stamping process of red envelopes, the belt conveyor 2 intermittently transports the red envelopes one by one to the hot stamping part of the hot stamping machine 3 via the positioning groove 6, so that the hot stamping machine 3 can perform hot stamping. When the hot stamping machine 3 starts working, it moves its hot stamping part down to hot stamp the red envelopes in the positioning groove 6 directly below the belt conveyor 2. After hot stamping, the hot stamping machine 3 moves its hot stamping part up while the belt conveyor 2 starts working, so that the belt conveyor 2 removes the hot stamped red envelopes from under the hot stamping part and transports the next red envelope to be hot stamped to the area directly below the hot stamping part. When the red envelope to be hot stamped is directly below the hot stamping part, the belt conveyor 2 stops working, and the hot stamping machine 3 moves its hot stamping part down again to perform hot stamping. This cycle is repeated to achieve continuous hot stamping processing of red envelopes one by one, improving the degree of automation and production efficiency.

[0037] As described above, during the operation of the belt conveyor 2, one of the rollers drives the pulley 12 to rotate via the pulley assembly 4, which in turn drives the pulley 20 to rotate via the belt 15. This causes the pulley 20 to rotate via the bevel gear set 19, which in turn drives the reciprocating screw 14 to rotate. Consequently, the reciprocating screw 14 drives the slide block 31 to move within the slide groove 13 via the sliding sleeve 17. During the operation of the belt conveyor 2, the reciprocating screw 14 drives the slide block 31 to move from the initial position at the left end to the right end and then back to the initial position at the left end within the slide groove 13 via the sliding sleeve 17.

[0038] As described above, during the process of the slide block 31 moving from the initial position at the left end to the right end within the slide groove 13, the slide block 31 pushes the slider 23 to move from left to right along the two guide grooves 7 via the push-pull rod 21, such as... Figure 3As shown, the two guide grooves 7 ensure that the slider 23 remains in a constant state during movement, guaranteeing smooth and reliable delivery of the red envelope paper. As the slider 23 moves to the right, it drives the tube shaft 24 and the suction cup to move to the right as well. During this process, the plug 37 is sealed by the spring 38 against the sealing ring 36. Furthermore, when the pin 32 on the slider 23 enters the bent section at the right end of the guide groove 7, it moves downwards longitudinally. This causes the slider 23 to synchronously drive the tube shaft 24 and the suction cup downwards longitudinally, allowing the suction cup to move closer to the topmost red envelope paper in the paper storage tube 26. When pin 32 is at the rightmost end of guide groove 7, the suction cup is in contact with the red envelope paper. At the same time, the rotation of belt 15 drives the impeller shaft inside pump wheel 10 to rotate through pulley 3 18, causing pump wheel 10 to draw air into tube shaft 24 through air pipe 11. This allows suction cup to hold the red envelope paper in place by utilizing the pressure difference. At this time, reciprocating screw 14 drives slide block 31 to move from right to left through sliding sleeve 17. This causes slide block 31 to apply a pulling force to slider 23 through push-pull rod 21, which in turn causes slider 23 to move the red envelope paper from right to left along guide groove 7 through tube shaft 24 and suction cup. When the slide block 31 moves to the leftmost position of the slide groove 13, the slider 23 is at the initial position on the left. The slider 23, through the tube shaft 24 and suction cup, moves the red envelope paper into the empty positioning groove 6 at the right end of the conveyor belt on the belt conveyor 2. During the leftward movement of the tube shaft 24 to the initial position, it drives the venting cylinder 8 and the plug 37 inside it to move to the left. When the plug 37 engages with the push rod 35, the push rod 35 applies a rightward thrust to the plug 37, causing the plug 37 to compress the spring 38, giving the spring 38 a restoring force. The red envelope paper is positioned at the fixed... When the tube shaft 24 is in the slot 6, the push rod 35 completely pushes the plug 37 out of the sealing ring 36, so that there is no pressure difference between the inside and outside of the tube shaft 24, and the suction cup releases the red envelope paper, realizing automatic paper feeding of the red envelope paper. The operation is simple and convenient, and there is no need for manual delivery of the red envelope paper to the bottom of the hot stamping component, which improves the safety of operation and greatly improves the production efficiency. When the tube shaft 24 drives the air vent 8 to move to the right, the push rod 35 moves away from the plug 37, and under the restoring force of the spring 38, the plug 37 seals the sealing ring 36, thus ensuring the airtightness of the suction cup when it holds the red envelope paper.

[0039] The pressure relief valve 25 on the tube shaft 24 is used to open when the pressure inside the tube shaft 24 is low and to maintain a suitable pressure difference between the inside and outside of the tube shaft 24, thereby preventing the red envelope paper from being deformed by a large pressure difference. When the pressure relief valve 25 reaches the set threshold, the pressure difference cannot push the plug 37 out of the sealing ring 36, thereby ensuring the airtightness of the suction cup when it holds the red envelope paper.

[0040] As mentioned earlier, after the suction cup removes the red envelope paper from the paper storage tube 26, the spring 28 causes the support plate 27 to push the remaining red envelope paper upwards, so that it can stably hold the red envelope paper next time. After the red envelope paper in the paper storage tube 26 is completely removed, the positioning pin 30 is removed, and the turntable 29 is rotated so that the full paper storage tube 26 is directly below the suction position of the suction cup. The turntable 29 is then fixed by using the positioning pin 30 through the through hole 34 and the positioning hole 33, and the empty paper storage tube 26 can be replenished, which saves time and effort.
