A blank holder device for corrugated box production

Abstract

This utility model relates to the technical field of corrugated cardboard box production, and discloses a pressing device for corrugated cardboard box production. It includes a feeding shell, a conveying assembly inside the feeding shell, and an adjusting assembly inside the feeding shell. This utility model operates a drive motor, which rotates a transmission rod at its output end. The transmission rod rotates a conveyor belt, which in turn rotates the transmission rod. Simultaneously, the conveyor belt transports the corrugated cardboard box from its surface towards the pressing device. The corrugated cardboard box is limited by a top driven roller, causing it to rotate passively. The driven roller is then limited by a guide slider and a limiting slider. The limiting slider prevents vertical displacement of the driven roller, thus limiting the corrugated cardboard box transported by the driven roller. This ensures that the corrugated cardboard box moves linearly towards the pressing device, improving the pressing quality of the corrugated cardboard box.

Description

Technical Field

[0001] This utility model relates to the technical field of corrugated cardboard box production, and in particular to a pressing device for corrugated cardboard box production. Background Technology

[0002] In the production of corrugated cardboard boxes, the edge-pressing device is a crucial component. It primarily ensures that the edges of the corrugated cardboard are effectively pressed during production, thereby improving the quality and stability of the boxes. Edge-pressing devices play a vital role in ensuring box quality and improving production efficiency. Choosing a suitable edge-pressing device can not only guarantee box quality but also improve production efficiency and reduce costs.

[0003] In existing corrugated box production, most edge-pressing devices use a conveyor belt to transport the corrugated box below the edge-pressing device, and then the edge-pressing device presses the corrugated box. However, relying solely on the conveyor belt to transport the corrugated box towards the edge-pressing device cannot limit the movement of the corrugated box. This can easily lead to displacement of the corrugated box when the top of the corrugated box is squeezed by the edge-pressing device while it is being transported by the conveyor belt, thus affecting the production quality of the corrugated box. Utility Model Content

[0005] This utility model is achieved by the following technical solution: a pressing device for corrugated carton production, including a feeding shell, a conveying component inside the feeding shell, and an adjusting component inside the feeding shell.

[0006] The conveying assembly includes a drive motor, the output end of which is fixedly connected to a transmission rod. The outer wall of the transmission rod is rotatably connected to the inner wall of the feeding housing. The transmission rod extends through the inner wall of the feeding housing. A transmission belt is throttlely connected to the outer wall of the transmission rod. A second transmission rod is throttlely connected to the inner wall of the transmission belt at the end away from the transmission rod. The outer wall of the second transmission rod is rotatably connected to the inner wall of the feeding housing. A guide groove is provided on the inner wall of the feeding housing. A guide slider is slidably connected to the inner wall of the guide groove. A driven roller is rotatably connected to the inner wall of the guide slider. A limit block is fixedly connected to the surface of the feeding housing. A limit groove is provided on the inner wall of the limit block. A limit slider is slidably connected to the inner wall of the limit groove. The outer wall of the driven roller is rotatably connected to the inner wall of the limit slider. A threaded rod is rotatably connected to the top of the limit slider. The outer wall of the threaded rod is threadedly connected to the inner wall of the limit block.

[0007] As a further improvement to the above solution, two guide grooves are provided, and the two guide grooves are symmetrically arranged with the transmission rod two as the center. Two guide sliders are provided, and the two guide sliders are symmetrically arranged with the transmission rod two as the center.

[0008] As a further improvement to the above solution, two limiting blocks are provided, which are symmetrically arranged around the center of the feeding shell, and two limiting sliders are provided, which are symmetrically arranged around the center of the feeding shell.

[0009] Through the above technical solution, the drive motor is operated, the output end of the drive motor rotates the transmission rod, the transmission rod rotates the transmission belt, the transmission belt rotates the transmission rod, and at the same time the transmission belt transports the corrugated carton on the surface towards the pressing device. Meanwhile, the corrugated carton is limited by the top driven roller, so that the corrugated carton drives the driven roller to rotate in a driven manner.

[0010] As a further improvement to the above solution, two limiting blocks are provided, which are symmetrically arranged around the center of the feeding shell, and two limiting sliders are provided, which are symmetrically arranged around the center of the feeding shell.

[0011] As a further improvement to the above solution, a top plate is provided at the top of the feeding shell, and a fixing bolt is threadedly connected to the inner wall of the top plate. The fixing bolt passes through the inner wall of the top plate and extends therefrom, and the fixing bolt is threadedly connected to the inner wall of the feeding shell.

[0012] As a further improvement to the above solution, an adjustment groove is provided on the top of the feeding shell, an avoidance groove is provided on the inner wall of the feeding shell, a guide T-shaped slider is slidably connected to the inner wall of the avoidance groove, a pressure rod is slidably connected to the inner wall of the adjustment groove, and the surface of the guide T-shaped slider is fixedly connected to the outer wall of the guide T-shaped slider.

[0013] As a further improvement to the above solution, a threaded rod is rotatably connected to the inner wall of the pressure rod, a pressure rod is slidably connected to the inner wall of the pressure rod, the inner wall of the pressure rod is threaded to the outer wall of the pressure rod, a limit spring is fixedly connected to the bottom of the pressure rod, and a guide base is fixedly connected to the end of the limit spring away from the pressure rod.

[0014] As a further improvement to the above solution, the surface of the pressure rod is provided with a relief groove II, the outer wall of the guide base is fixedly connected to a connecting rod, the outer wall of the connecting rod is slidably connected to the inner wall of the relief groove II, and the inner wall of the connecting rod is rotatably connected to a pressure roller.

[0015] With the above technical solution, when the corrugated carton on the conveyor belt moves towards the bottom of the pressure roller, the top of the corrugated carton pushes the pressure roller upward. The pressure roller drives the connecting rod and the guide base to slide upward along the inner wall of the edge pressing rod and the clearance groove. At the same time, after the pressure roller is subjected to the downward pressure of the top limiting spring, the limiting spring presses down on the pressure roller, and then the pressure roller presses the edge of the corrugated carton.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention utilizes a drive motor to rotate a transmission rod, which in turn rotates a conveyor belt. The conveyor belt then rotates the transmission rod, simultaneously conveying the corrugated cardboard box towards the pressing device. The corrugated cardboard box is simultaneously limited by a top driven roller, causing it to rotate. The driven roller is then further limited by a guide slider and a limiting slider, preventing vertical displacement. This limits the movement of the corrugated cardboard box conveyed by the driven roller, ensuring linear motion as it moves towards the pressing device and improving the pressing quality of the corrugated cardboard box.

[0018] This invention works by having the corrugated cardboard box on the conveyor belt move towards the bottom of the pressure roller. The top of the corrugated cardboard box pushes the pressure roller upward, causing the pressure roller to drive the connecting rod and guide base to slide upward along the inner wall of the edge pressing rod and the second clearance groove. At the same time, the pressure roller is subjected to the downward pressure of the top limiting spring, causing the limiting spring to press down on the pressure roller. Then, the pressure roller presses the edge of the corrugated cardboard box. Furthermore, by rotating the second threaded rod, the pressure rod slides downward along the inner wall of the edge pressing rod and the outer wall of the second threaded rod. Then, the pressure rod compresses the limiting spring downward, increasing the downward pressure of the limiting spring on the guide base, thereby increasing the downward thrust of the guide base on the connecting rod. Finally, the connecting rod presses down on the pressure roller, thereby increasing the indentation depth of the pressure roller on the corrugated cardboard box. Attached Figure Description

[0033] Two guide grooves 205 are provided, and the two guide grooves 205 are symmetrically arranged with the transmission rod 204 as the center. Two guide sliders 206 are provided, and the two guide sliders 206 are symmetrically arranged with the transmission rod 204 as the center.

[0034] There are two limit blocks 208, which are symmetrically arranged around the center of the feeding shell 1. There are also two limit sliders 210, which are symmetrically arranged around the center of the feeding shell 1.

[0035] A top plate 301 is provided at the top of the feeding housing 1. A fixing bolt 302 is threadedly connected to the inner wall of the top plate 301. The fixing bolt 302 passes through the inner wall of the top plate 301 and extends thereto. The fixing bolt 302 is threadedly connected to the inner wall of the feeding housing 1.

[0036] The top of the feeding housing 1 is provided with an adjustment groove 303, and the inner wall of the feeding housing 1 is provided with a clearance groove 304. A guide T-shaped slider 305 is slidably connected to the inner wall of the clearance groove 304. A pressure rod 306 is slidably connected to the inner wall of the adjustment groove 303. The surface of the guide T-shaped slider 305 is fixedly connected to the outer wall of the guide T-shaped slider 305.

[0037] A threaded rod 307 is rotatably connected to the inner wall of the pressure rod 306, and a pressure rod 309 is slidably connected to the inner wall of the pressure rod 306. The inner wall of the pressure rod 309 is threaded to the outer wall of the pressure rod 306. A limit spring 308 is fixedly connected to the bottom of the pressure rod 309, and a guide base 310 is fixedly connected to the end of the limit spring 308 away from the pressure rod 309.

[0038] The pressure bar 306 has a relief groove 311 on its surface. A connecting rod 312 is fixedly connected to the outer wall of the guide base 310. The outer wall of the connecting rod 312 is slidably connected to the inner wall of the relief groove 311. A pressure roller 313 is rotatably connected to the inner wall of the connecting rod 312.

[0039] The implementation principle of the edge-pressing device for corrugated carton production in this embodiment is as follows: The drive motor 201 is operated, and the output end of the drive motor 201 rotates the transmission rod 202. The transmission rod 202 rotates the conveyor belt 203, and the conveyor belt 203 rotates the transmission rod 204. Simultaneously, the conveyor belt 203 transports the corrugated carton on the surface towards the edge-pressing device. At the same time, the corrugated carton is limited by the top driven roller 207, causing the corrugated carton to drive the driven roller 207 to rotate passively. Then, the driven roller 207 is limited by the guide slider 206 and the limiting slider 210. The limiting slider 210 is limited to prevent the driven roller 207 from moving up and down, thereby pressing the corrugated carton transported by the driven roller 207. The limit switch ensures that the corrugated carton moves linearly towards the pressing device, improving the pressing quality of the corrugated carton. When the corrugated carton on the conveyor belt 203 moves towards the bottom of the pressure roller 313, the top of the corrugated carton pushes the pressure roller 313 upward. The pressure roller 313 drives the connecting rod 312 and the guide base 310 to slide upward along the inner wall of the pressing rod 306 and the second clearance groove 311. At the same time, the pressure roller 313 is subjected to the downward pressure of the top limit spring 308, causing the limit spring 308 to press down on the pressure roller 313. Then, the pressure roller 313 presses the corrugated carton. Furthermore, by rotating the second threaded rod 307, the pressure rod 309 can be moved downward along the inner wall of the pressing rod 306 and the outer wall of the second threaded rod 307. The sliding mechanism then compresses the limiting spring 308 downwards via the pressure rod 309, increasing the downward pressure of the limiting spring 308 on the guide base 310. This increases the downward thrust of the guide base 310 on the connecting rod 312. The connecting rod 312 then presses down on the pressure roller 313, increasing the indentation depth of the pressure roller 313 on the corrugated cardboard box. Rotating the threaded rod 211 causes it to move upwards along the inner wall of the limiting block 208. Simultaneously, the threaded rod 211 pulls the limiting slider 210 upwards along the limiting groove 209. The limiting slider 210 pulls the driven roller 207, which in turn pulls the guide slider 206 upwards along the guide groove 205, thus adjusting the distance between the driven roller 207 and the conveyor belt 203. The spacing allows the equipment to process corrugated boxes of different thicknesses, increasing its flexibility and applicability. By unscrewing the fixing bolt 302 upwards, the fixing bolt 302 is disengaged from the top plate 301 and the inside of the feeding shell 1. Then, the pressing rod 306 can be pulled upwards. The pressing rod 306 drives the guide T-shaped slider 305 to slide upwards along the clearance groove 304, thereby disengaging the top of the pressing rod 306 from the inside of the adjustment groove 303. Then, the pressing rod 306 is adjusted to different positions inside the adjustment groove 303, thereby driving the threaded rod 307 and the guide base 310 through the pressing rod 306. The guide base 310 drives the connecting rod 312 and the pressure roller 313, thereby creased different positions of the corrugated box.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
