[0002] The detection device of transparent paper and wire joint of small box transparent paper packaging machine is suitable for small box transparent paper packaging machine. Small box transparent paper packaging machine is one of the single machines of the packaging unit, and its main function is to pack hard box cigarette packs with transparent paper.

[0003] For example, the public document with application number 202022460580.6 discloses a detection device for transparent paper and pull wire joints of a small box transparent paper packaging machine. The utility model can detect transparent paper of the entire width. No matter where the joint tape is affixed, it can ensure accurate detection of the joint, thereby ensuring the quality of the product. However, the connection between the detection device and the assembly parts of the detection device is fixed with bolts, which makes the installation and disassembly process cumbersome and inconvenient for the rapid disassembly and assembly of the detection device. At the same time, the transparent paper and the pull wire directly pass through the middle of the detection device, resulting in movement offset or installation offset. The transparent paper and the pull wire will contact the edge of the detection device for friction, resulting in breakage and damage, thereby affecting the detection accuracy and quality of the transparent paper and the pull wire.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a transparent paper wire joint detection device is proposed. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-Figure 3 As shown, a transparent paper wire joint detection device includes an assembly mechanism 2 arranged on the surface of an assembly frame 1, a fork-type photoelectric detector 3 is arranged above the assembly frame 1, an insert block 4 is fixedly arranged below the outer surface of the fork-type photoelectric detector 3, a wiring unit 5 is fixedly installed at the rear end of the fork-type photoelectric detector 3, and a protective mechanism 6 is arranged on the inner surface of the fork-type photoelectric detector 3. The assembly mechanism 2 includes a slot 201 opened on the front side above the surface of the assembly frame 1, the slot 201 and the insert block 4 are both arranged in a "T" shape, a sink groove 202 is opened below the front end of the inner surface of the slot 201, the assembly mechanism 2 also includes a thrust spring 203 fixedly installed at the bottom of the inner surface of the sink groove 202, a baffle 204 is fixedly installed on the upper end of the thrust spring 203, the front side of the surface of the baffle 204 is arranged as an inclined surface, and the upper end of the baffle 204 is located in the transverse cavity of the slot 201, and the assembly mechanism 2 also includes a pull rod 205 fixedly installed at the middle of the bottom end of the baffle 204, and the bottom end of the pull rod 205 passes through the bottom of the assembly frame 1.

[0023] Furthermore, the insert block 4 and the slot 201 are provided with mutually matching “T”-shaped blocks and “T”-shaped slots, so that the assembly frame 1 can be connected to the fork-type photoelectric detector 3 by plugging the slot 201 and the insert block 4 into each other.

[0024] Furthermore, the front side of the baffle 204 is set as an inclined surface, that is, the inclined surface is used to push the baffle 204 downward and converge into the sink 202 when the plug 4 is inserted into the slot 201, so that the plug 4 can be smoothly inserted into the slot 201 for installation.

[0025] Furthermore, the thrust spring 203 can push the baffle 204 to return to its original position, so that after the insert block 4 is fully inserted, the baffle 204 can block the insertion opening of the slot 201, so that the insert block 4 is stably inserted into the slot 201 to prevent it from slipping.

[0026] Furthermore, by pulling down the pull rod 205, the baffle 204 can be moved down a second time and gathered into the sink 202. At this time, the insertion port of the slot 201 is reopened, and the insert block 4 can be slid out of the slot 201, thereby completing the disassembly.

[0027] like Figure 2 and Figure 4 As shown, the protective mechanism 6 includes protrusions 601 fixedly installed at the four corners of the upper and lower sides of the inner surface of the fork-type photoelectric detector 3, and sliding grooves 602 are provided on the front and rear opposite sides of the protrusions 601. The protective mechanism 6 also includes a telescopic spring 603 fixedly installed on the inner surface of the sliding groove 602, and a movable block 604 is fixedly set at one end of the telescopic spring 603. The protective mechanism 6 also includes a roller 605 rotatably set in the middle of one side opposite to the movable block 604, and the movable block 604 slides in contact with the inner surface of the sliding groove 602.

[0028] Furthermore, the four rollers 605 are respectively located at the upper and lower ends of the inner surfaces on the left and right sides of the fork-type photoelectric detector 3, that is, when the transparent paper and the pull wire connector are pulled for detection, they will touch the rollers 605, and the rollers 605 will rotate instead of being damaged by friction at the edge of the contact fork-type photoelectric detector 3.

[0029] Furthermore, the telescopic spring 603 can drive the movable block 604 to move up and down, and then move the roller 605 up and down, so that the protrusion of the pull wire joint can speculate on the downward movement of the roller 605, and reserve enough stretching force to allow the pull wire joint to pass through, thereby preventing the roller 605 from lifting the pull wire joint, causing the two ends of the joint to be stuck in the air and break.

[0030] Working principle: When using the transparent paper pull-wire joint detection device, first, the assembly frame 1 is assembled with the removal machine using bolts, and then the fork-type photoelectric detector 3 is inserted into the slot 201 using the plug block 4, and the baffle 204 is pushed and gathered into the sink 202 using the inclined surface. When the plug block 4 is fully inserted, the thrust spring 203 uses its own elastic force to push the baffle 204 to reset and block the socket of the slot 201, so that the plug block 4 is stably installed inside the slot 201, and the fork-type photoelectric detector 3 is fixedly connected to the assembly frame 1. Then, the wiring unit 5 and the transmission line are used to connect the fork-type photoelectric detector 3 to the interactive PC end. The transparent paper and the pull-wire joint are located in the middle of the upper and lower side rollers 605 and pass through the middle of the fork-type photoelectric detector 3. The fork-type photoelectric detector 3 uses the joint point and the transparent paper point to be different. The same light return value is provided to the interactive PC terminal to detect the pull-wire joint. In the case of normal transparent paper without joints, the return value is 2000. In the case of joints, the joints are raised and the return value is 500. Based on this value, the interactive PC terminal machine controls the rejection device to reject or retain the cigarette packs. During the detection of the movement of transparent paper and the pull-wire joint, the telescopic spring 603 can drive the movable block 604 to move up and down, and then move the roller 605 up and down, so that the protrusion of the pull-wire joint can speculate on the downward movement of the roller 605, and reserve enough stretching force for the pull-wire joint to pass through, so as to prevent the roller 605 from lifting the pull-wire joint, causing the two ends of the joint to be suspended in the air and break. This is the working principle of the transparent paper pull-wire joint detection device.
