Description

Technical Field

[0001] This invention relates to the field of paper splicing machine technology, and more specifically to a safety mechanism for the paper splicing carriage of a paper splicing machine. Background Technology

[0002] Generally used in corrugated cardboard production lines, it is installed inside the automatic paper splicer and is a safety mechanism that protects operators when the paper splicer moves inside the splicer. It is a safety mechanism that protects personnel and property when the paper splicer has finished splicing paper on one side and moves to the other side to prepare for splicing paper, or when the splicer fails to splice paper or malfunctions.

[0003] The traditional operating method is that when the paper receiving carriage moves from one side to the other, if someone illegally enters the machine or there is another object, the paper receiving carriage will continue to run until the object is squeezed to the squeezing point and cannot move, which will cause personal injury and property damage.

[0004] Therefore, there is an urgent need to develop a safety mechanism for the paper receiving carriage of a paper receiving machine to ensure personnel safety and prevent property loss. Summary of the Invention

[0005] The main objective of this invention is to provide a safety mechanism for the paper receiving carriage of a paper receiving machine, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A paper receiving carriage safety mechanism for a paper receiving machine includes a left-side mechanism and a right-side mechanism. The left-side mechanism consists of a first left sensing component, a second left sensing component, and a left sensing bracket. The first left sensing component and the second left sensing component are mounted on the left side of the paper receiving carriage via the left sensing bracket. The first left sensing component and the second left sensing component have the same structure. The right-side mechanism consists of a first right sensing component and a second right sensing component. The first right sensing component and the second right sensing component are mounted on the right side of the paper receiving carriage. The first right sensing component and the second right sensing component have the same structure.

[0008] In the above description, a more preferred embodiment is that the left-side mechanism includes a left push rod and a left induction switch mounted on the left induction bracket. The left push rod has left guide screws at both ends, and a left compression spring is sleeved on the outside of the left guide screw. The left compression spring has left guide blocks at both ends, and the left guide screw passes through the left compression spring and the left guide blocks to be connected and fixed to the left induction bracket.

[0009] In the above description, a more preferred embodiment is that the left push rod is provided with a left bracket and a left clamping block, and the left proximity switch is fixed to the left push rod by the left bracket and the left clamping block.

[0010] In the above description, a more preferred embodiment is that the right-side mechanism includes a right push rod, a right proximity switch, and a right sensing frame installed on the right side of the paper receiving carriage. The right push rod has mounting brackets at both ends. One end of the mounting bracket is fixed to the paper receiving carriage, and the other end of the mounting bracket has a right guide screw. A right compression spring is provided outside the right guide screw. Right guide blocks are provided at both ends of the right compression spring. The right guide screw passes through the right compression spring and the right guide blocks and is connected and fixed to the mounting bracket.

[0011] In the above description, a more preferred embodiment is that the right sensor frame has a Z-shaped structure and is fixed to the paper receiving carriage by screws.

[0012] In the above description, a more preferred embodiment is that the right push rod is provided with a right bracket and a right clamping block, and the right proximity switch is fixed to the right push rod by the right bracket and the right clamping block.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] With safety mechanisms installed on both sides of the paper receiving carriage, if someone illegally enters the machine during operation and presses the start button without the knowledge of the outside personnel, the paper receiving carriage will automatically stop when it hits an object. This is because the compression spring will be compressed under slight force, and after being compressed by about one centimeter, the proximity switch will sense the sensing block and thus stop the paper receiving carriage, thereby avoiding personal injury and property damage.

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-3 As shown, an embodiment of the paper receiving carriage safety mechanism of the paper receiving machine in this solution includes a left-side mechanism 1 and a right-side mechanism 2. The left-side mechanism 1 consists of a first left sensing group 11 pieces, a second left sensing group 12 pieces, and a left sensing bracket 13. The first left sensing group 11 pieces and the second left sensing group 12 pieces are installed on the left side of the paper receiving carriage 3 through the left sensing bracket 13. The first left sensing group 11 pieces and the second left sensing group 12 pieces have the same structure. The right-side mechanism 2 consists of a first right sensing group 21 pieces and a second right sensing group 22 pieces. The first right sensing group 21 pieces and the second right sensing group 22 pieces are installed on the right side of the paper receiving carriage 3. The first right sensing group 21 pieces and the second right sensing group 22 pieces have the same structure.

[0021] After this safety mechanism is installed, if someone enters the machine without permission during operation and presses the start button without the knowledge of the outside personnel, the paper receiving carriage 3 will automatically stop when it encounters an object. This is because the compression spring will be compressed under slight force. After being compressed by about one centimeter, the proximity switch will sense the sensing block and thus stop the paper receiving carriage 3, avoiding personal injury and property damage.

[0022] Specifically, the left-side mechanism 1 includes a left push rod 111 and a left proximity switch 112 mounted on the left sensing bracket 13. The left push rod 111 has left guide screws 113 at both ends, and a left compression spring 114 is sleeved around the left guide screws 113. Left guide blocks 115 are mounted at both ends of the left compression spring 114. The left guide screws 113 pass through the left compression spring 114 and the left guide blocks 115 and are connected and fixed to the left sensing bracket 13. For more stable installation, the left push rod 111 has a left bracket 116 and a left clamping block 117. The left proximity switch is fixed to the left push rod 111 via the left bracket 116 and the left clamping block 117. The left bracket 116 and the left clamping block 117 provide a more secure fixation and facilitate easier assembly and disassembly.

[0023] In addition, the right-side mechanism 2 includes a right push rod 211, a right proximity switch 212, and a right sensing frame 213 mounted on the right side of the paper receiving carriage 3. The right push rod 211 has mounting brackets 214 at both ends. One end of each mounting bracket 214 is fixed to the paper receiving carriage 3, and the other end of each mounting bracket 214 has a right guide screw 215. A right compression spring 216 is provided outside the right guide screw 215. Right guide blocks 217 are provided at both ends of the right compression spring 216. The right guide screw 215 passes through the right compression spring 216 and the right... The guide block 217 is connected and fixed to the mounting bracket 214; the right sensing frame 213 has a Z-shaped structure and is fixed to the paper receiving carriage 3 by screws. The right sensing frame 213 adopts a Z-shaped design to avoid the installation of the paper receiving carriage 3 motor and the frame track; in order to make the installation more stable, the right push rod 211 is provided with a right bracket 218 and a right clamping block 219. The right proximity switch 212 is fixed to the right push rod 211 through the right bracket 218 and the right clamping block 219. The right bracket 218 and the right clamping block 219 make the fixation more secure and the disassembly and assembly simpler.

[0024] The working principle and usage of this invention are as follows: During operation, when the paper receiving carriage 3 moves from the left paper receiving area 4 to the right paper receiving area 5 or from the right paper receiving area 5 to the left paper receiving area 4, if a person enters the machine during operation, the push rods on both sides of the paper receiving carriage 3 will be the first to encounter the object. When the push rods encounter the object, they compress the spring, causing the proximity switch installed on the push rod to sense the sensor frame. In this way, the machine will stop running immediately. After the fault is cleared, the machine's reset switch is pressed, and the machine will start running again.

[0025] Any aspects of this invention not described in detail are well-known to those skilled in the art.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
