Description

Technical Field

[0001] This utility model relates to the technical field of raw paper roll weighing devices, and in particular to a raw paper roll weighing device for corrugated cardboard production. Background Technology

[0002] Corrugated cardboard is a multi-layered bonded structure with high mechanical strength, capable of withstanding impacts and drops during handling. The actual performance of corrugated boxes depends on three factors: the characteristics of the core paper and the cardboard itself, and the structure of the box itself; existing production lines cannot weigh remaining rolls of raw paper during operation, therefore a raw paper roll weighing device is needed to weigh the raw paper rolls.

[0003] A search revealed a public disclosure (announcement) number: CN210625833U, which discloses an intelligent weighing device for raw paper rolls in a corrugated cardboard production line, belonging to the field of production equipment technology. The device includes a machine body with electric telescopic rods installed at both ends of the bottom. A support plate is welded to the bottom of each telescopic rod, and weighing sensors are fixedly installed at both ends of the lower surface of the support plate. This invention features a simple structure, convenient operation, and good performance. The trolley allows for convenient and labor-saving loading and unloading of raw materials. The weighing sensors weigh the corrugated paper rolls suspended on an L-shaped boom, and the weighing signal is transmitted to a display controller for real-time weight display. The remaining amount of raw material rolls can be displayed in real-time via the controller, making it more convenient to use. An alarm can also be issued to remind the user to replace the remaining material when it is too low, making it extremely convenient to use.

[0004] Although the above solution can issue an alarm to remind users to replace the material when there is too little material left, the raw paper rolls are usually recycled. When workers throw them into the weighing box, the impact is too great and can easily damage the weighing box or the weighing sensor. In addition, it is not convenient to adjust the feeding position and does not squeeze the raw paper rolls, resulting in a limited number of weighings at one time. Utility Model Content

[0005] The main purpose of this utility model is to provide a weighing device for raw paper rolls used in corrugated cardboard production. By setting up a measuring unit, it solves the problem that raw paper rolls are usually recycled, and the impact force when workers throw them into the weighing frame is too large, which can easily damage the weighing frame or the weighing sensor. By setting up a feeding unit, it solves the problem that it is not convenient to adjust the feeding position, and the raw paper rolls are not squeezed, resulting in a limited number of weighings at one time.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A weighing device for raw paper rolls used in corrugated cardboard production includes a main body, a measuring unit disposed inside the main body, and a feeding unit disposed at the top of the measuring unit.

[0008] The measuring unit includes a disassembly plate disposed on the front of the main body, a display screen disposed on the top of the disassembly plate, a weighing component disposed inside the main body, and a pressure relief component disposed on the top of the weighing component.

[0009] The feeding unit includes a guide frame disposed at the top of the main body, a linkage component disposed on the side of the guide frame, and an extrusion component disposed at the bottom of the linkage component.

[0010] Preferably, the weighing component in the measuring unit includes a placement slot at the bottom of the main body, multiple weighing sensors disposed inside the placement slot, a lifting plate fixedly connected to the top of the multiple weighing sensors, and a receiving frame fixedly connected to the top of the lifting plate.

[0011] Preferably, the stress relief component in the measuring unit includes vertical grooves formed on the two inner sides of the receiving frame, extension grooves connecting the two sides of the vertical grooves, an elastic column disposed in the middle of the vertical grooves, a spring disposed on the surface of the elastic column, positioning blocks fixedly connected to the upper and lower ends of the elastic column, extension blocks fixedly connected to the two sides of the positioning blocks, and a shock-absorbing strip fixedly connected between two opposing positioning blocks.

[0012] Preferably, the extension block in the measuring unit extends into the corresponding extension groove.

[0013] Preferably, the linkage component in the feeding unit includes a slide groove on both sides of the top of the main body, a slider disposed inside the slide groove and fixedly connected to the guide frame, a transverse groove on the bottom of the slide groove, a first motor disposed inside the transverse groove, a first telescopic rod disposed at one end of the first motor, a limiting plate fixedly connected to one end of the first telescopic rod, and a plug-in post fixedly connected to one end of one of the limiting plates.

[0014] Preferably, the other limiting plate in the feeding unit has a circular hole inside that matches the insertion post.

[0015] Preferably, the extrusion assembly in the feeding unit includes two vertical plates fixedly connected to the top of the main body, a limiting seat fixedly connected to one end of the vertical plates, a groove opened inside the limiting seat, a second motor disposed inside the groove, a second telescopic column fixedly connected to one end of the second motor, an extrusion plate fixedly connected to one end of the second telescopic column, and a plurality of extrusion columns fixedly connected to one side of the extrusion plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] I. In this utility model, by setting up a feeding unit, the raw paper roll is dropped into the main body through a guide frame. The guide frame can be pushed to move the slider in the chute, thereby adjusting the position of the guide frame. Subsequently, the first motor can be started to drive the first telescopic rod to retract, so that the raw paper roll falls and hits the limiting seat during the falling process, effectively reducing the impact force of the raw paper roll. Under the action of the second motor and the second telescopic column, the extrusion plate and extrusion column are driven to extrude the raw paper roll. In this way, more raw paper rolls can be weighed at one time in the limited space of the receiving frame.

[0018] Second, in this utility model, by setting up the measuring unit, when the raw paper roll falls into the receiving frame, the raw paper roll will come into contact with the two shock-absorbing belts. Under the action of the elastic column and the spring, the positioning blocks will move closer to each other, which reduces the impact of the raw paper roll on the receiving frame and the weighing sensor, and improves the service life of the device.
