A one-button changeover device for the pusher of a continuous automatic cartoning machine

Abstract

A one-click change device for the pusher of a continuous automatic cartoning machine includes a base, a movable pressure block rotatably mounted on the base, and a pusher detachably connected to the movable pressure block. The pusher includes a working end and a connecting rod connected to each other. The connecting rod is inserted into a slot in the base and has a groove. The front end of the movable pressure block has a protrusion that mates with the groove, and the rear end of the movable pressure block serves as a force-applying end to control the front end of the movable pressure block to lift, causing the protrusion to disengage from the groove. A spring is provided between the movable pressure block and the base, with both ends of the spring extending into the grooves of the base and the movable pressure block respectively. The engagement between the base and the movable pressure block prevents the spring from popping out. The spring's elastic force presses down the front end of the movable pressure block, which is then engaged by the protrusion within the pusher's groove. This invention enables quick assembly and disassembly of the pusher, achieving one-click changeover for different pusher models.

Description

Technical Field

[0001] This utility model belongs to the field of packaging equipment, specifically relating to a one-button changeover device for the pusher of a continuous automatic cartoning machine. Background Technology

[0002] In automated packaging processes, continuous automatic cartoning machines use pushers to insert products into open cartons. When product models or sizes differ, matching pushers need to be replaced. The usual method for replacing pushers involves removing the screws that secure the pusher, replacing it with a new, suitable pusher, and then tightening the screws again. After fixing, various parameters need to be readjusted for matching, making the entire changeover process cumbersome and complex. Utility Model Content

[0003] The purpose of this invention is to provide a one-click change device for the pusher of a continuous automatic cartoning machine. By utilizing spring pressure and a lever mechanism, the pusher can be quickly disassembled and assembled, thereby achieving one-click change of different pusher models and simplifying the entire pusher change process.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a one-button change device for the pusher of a continuous automatic cartoning machine, comprising a base, a movable pressure block rotatably mounted on the base, and a pusher detachably connected to the movable pressure block;

[0005] The pusher includes a pusher working end and a pusher connecting rod connected together. The pusher connecting rod is inserted into a slot in the base and has a groove.

[0006] The front end of the movable pressure block is provided with a protrusion that mates with the groove, and the rear end of the movable pressure block serves as the force-applying end, used to control the front end of the movable pressure block to lift up, so that the protrusion disengages from the groove.

[0007] A spring is provided between the movable pressure block and the base. One end of the spring is connected to the base, and the other end is connected to the movable pressure block. The spring causes the front end of the movable pressure block to press down through its elastic force, and the protrusion is locked in the groove of the pusher connecting rod.

[0008] A pressure bar is provided at the rear end of the movable pressure block.

[0009] The spring is located between the rotating shaft and the force-applying end, and the movable pressure block and the base are provided with spring grooves for installing the spring.

[0010] Both the push rod and the slot have square cross-sections.

[0011] The protrusion is a spherical protrusion, and the groove is a conical groove.

[0012] The pusher working end and the pusher connecting rod are connected by screws.

[0013] The front end of the movable pressure block is provided with a limit rod, and the two sides of the base are provided with limit grooves for supporting the limit rod.

[0014] The movable pressure block is rotatably connected to the base via a rotating shaft.

[0015] The one-click replacement principle and beneficial effects of this utility model are as follows: When removing the existing pusher, simply press the pressure rod at the rear end of the lever mechanism to lift the movable pressure block at the front end of the lever mechanism. The protrusion at the bottom of the movable pressure block disengages from the groove at the rear end of the pusher, allowing the entire pusher to be removed directly and replaced with a new, suitable pusher. After releasing the pressure rod, the movable pressure block returns to its original position under the elastic force of the spring, and the protrusion at the bottom of the movable pressure block engages with the groove at the rear end of the pusher, thus locking the pusher. The entire replacement process does not require disassembling screws, removing the pusher assembly from the entire cartoning machine, or readjusting the signals. After the replacement, cartoning can be started directly. Attached Figure Description

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention in any way.

[0022] See attached document Figure 1-3 As shown, the one-button changeover device includes a base, a pusher, a movable pressure block, a spring, and a pressure rod.

[0023] The base 1 has a U-shaped mounting groove on its upper part. The movable pressure block 6 is disposed in the mounting groove, and a rotating shaft 2 is provided on the movable pressure block 6. The two ends of the rotating shaft 2 are rotatably supported in the shaft holes on both sides of the mounting groove, thereby realizing the rotation of the movable pressure block 6 around the rotating shaft 2. A pressure rod 8 is provided at the rear end of the movable pressure block 6 for manual operation of the movable pressure block 6. The lower surface of the front end of the movable pressure block 6 is provided with a downwardly protruding protrusion 601.

[0024] The pusher 3 includes a front pusher working end 301 and a rear pusher connecting rod 302, which are connected by screws. The pusher connecting rod 302 has a square cross-section and is inserted into a slot 101 on the base 1. The upper surface of the pusher connecting rod 302 has a recessed groove 303. The square shape of the pusher connecting rod and the slot prevents the pusher from rotating.

[0025] Specifically, in this embodiment, the protrusion 601 is a spherical protrusion, and the groove 303 is a conical groove.

[0026] Specifically, in this embodiment, the rotating shaft 2 is detachably mounted on the movable pressure block 6. The rotating shaft 2 is inserted into the mounting hole of the movable pressure block 6, with both ends protruding from the mounting hole. Tightening screws are provided in the direction perpendicular to the mounting hole. Tightening the tightening screws locks the position of the rotating shaft 2.

[0027] A spring 7 is provided between the pressure rod 8 and the rotating shaft 2. The spring 7 is installed in the spring groove inside the movable pressure block 6. The lower end of the spring 7 protrudes from the spring groove and is fixedly connected to the base 1. The upper end of the spring 7 is fixed on the spring groove. With the help of the elastic force of the spring 7, the rear end of the movable pressure block 6 is pushed upward and the front end is pressed downward, so that the protrusion is locked in the groove, thereby locking the pusher.

[0028] This invention uses a combination of a movable pressure block 6 and a pressure rod 8 as a lever mechanism, with the pivot 2 as the fulcrum. When the push handle 3 needs to be removed for replacement, simply press down the pressure rod 8 manually to lift the front end of the movable pressure block 6, causing the protrusion 601 to leave the groove 303, thus releasing the lock on the push handle 3. The push handle 3 can then be pulled out, and the push handle 3 to be replaced can be inserted into the slot 101. Release the pressure rod 8, and the front end of the movable pressure block 6 will press down under the elastic force of the spring 7, causing the protrusion 601 to lock in the groove 303, thus locking the newly replaced push handle.

[0029] Furthermore, a limiting rod 4 is provided at the front end of the movable pressure block 6, and limiting grooves 5 are provided on both sides of the base 1. When the pusher 3 is locked by the movable pressure block 6, the limiting rod 4 falls into the limiting groove 5 to control the depth of the front end of the movable pressure block 6.

[0030] Specifically, the limiting rod 4 can be detachably installed using the installation method of the rotating shaft 2.

[0031] Figure 4 A schematic diagram of the one-click change device of this utility model installed on the pusher assembly is given. During installation, the base 1 is fixedly connected to the slider 9 on the pusher assembly with screws, and the pusher working end 301 at the front end of the pusher is slidably connected to the slide groove 10 on the pusher assembly. Under the action of the slider 9, the pusher 3 can be extended and retracted to push the product that needs to be put into the packaging box into the packaging box.

[0032] The above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Those skilled in the art should understand that modifications or equivalent substitutions can be made to the specific implementation of this utility model with reference to the above embodiments. Any modifications or equivalent substitutions that do not depart from the spirit and scope of this utility model are within the protection scope of the pending claims.
