Description

Technical Field

[0001] This utility model belongs to the field of cardboard processing, and in particular relates to a cardboard processing feeding device. Background Technology

[0002] As a crucial component of the packaging and printing industries, the paperboard processing sector's production efficiency and product quality directly impact the competitiveness of downstream industries. The feeding stage is particularly critical in paperboard processing, directly determining whether the paperboard can accurately and efficiently proceed to the next stage.

[0003] However, traditional paperboard feeding devices have revealed a series of problems in practical applications, such as the paperboard easily deviating during feeding and the pressure rollers not being able to be finely adjusted up and down. These problems seriously restrict the development of the paperboard processing industry. Utility Model Content

[0004] In view of the above problems, the purpose of this utility model is to provide a paperboard processing feeding device, which aims to solve the problems of paperboard easily deviating during the feeding process and the pressure rollers not being able to be finely adjusted up and down in the existing paperboard processing feeding devices.

[0005] The present invention adopts the following technical solution:

[0006] The cardboard processing feeding device includes a machine base with a slot on its table surface. A pressure roller and a feeding roller are rotatably mounted on the machine base at positions above and below the slot, respectively. A feeding motor is mounted on the machine base to drive the feeding roller. A pair of fixed seats are mounted on the machine base, each containing a bearing. The pressure roller is rotatably mounted between the two bearings. A pre-pressing assembly is mounted on the fixed seat opposite the bearing. A pair of limiting assemblies are mounted on the pressure roller, each including a limiting frame rotatably mounted on the pressure roller shaft. The bottom of the limiting frame extends into the machine base and has a base frame. A rotating rod is mounted inside the machine base, with a pair of eccentric wheels supporting the base frame on the same side. A baffle is mounted on the eccentric wheels, located outside the base frame. An adjustment mechanism is mounted on the machine base to adjust the height of the pressure roller.

[0007] Furthermore, one end of the rotating rod extends out of the machine base and is equipped with a gear. The adjustment mechanism includes a threaded sleeve installed on the side wall of the machine base, a lead screw inserted inside the threaded sleeve, a rotating handle at the top of the lead screw, and a straight rack at the bottom, which is installed with the gear.

[0008] Furthermore, the pre-compression assembly includes a sliding sleeve mounted on the fixed base, a sliding rod inserted inside the sliding sleeve, a pressure plate positioned at the bottom of the sliding rod opposite the bearing, and a compression spring positioned on the sliding rod between the pressure plate and the sliding sleeve.

[0009] Furthermore, the rack is slidably mounted on the machine base.

[0010] The beneficial effects of this utility model are as follows: In actual practice, the actual height of the pressure roller can be slightly adjusted up and down to adapt to cardboard of different thicknesses. When it is necessary to adjust the height of the pressure roller, simply rotate the rotating handle. The rotating handle drives the lead screw to rotate, and the lead screw moves up and down inside the lead sleeve. The rack moves up and down, and the rack drives the rotating rod to rotate through the gear. During the rotation of the rotating rod, the two eccentric wheels rotate simultaneously. During the rotation of the eccentric wheels, the base frame moves vertically by a small amplitude, and the pressure roller also moves up and down by a small amplitude, thereby completing the adjustment of the pressure roller height.

[0015] To make the objectives, technical solutions, and advantages of this utility model patent clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0016] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0017] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0018] Combination Figure 1-4As shown, the cardboard processing feeding device includes a machine base 1. The table surface of the machine base 1 has a slot. A pressure roller 2 and a feeding roller 3 are rotatably mounted on the machine base 1 at the upper and lower positions opposite to the slot, respectively. A feeding motor 4 is provided on the machine base 1 to drive the feeding roller 3 to rotate. A pair of left and right fixed seats 5 are provided on the machine base 1. Bearings 6 are inside the fixed seats 5. The pressure roller 2 is rotatably mounted between the two bearings 6. A pre-pressing component is provided on the fixed seats 5 opposite to the bearings 6. A pair of left and right limiting components are provided on the pressure roller 2. The limiting components include a limiting frame 7 rotatably mounted on the shaft of the pressure roller 2. The bottom of the limiting frame 7 extends into the machine base 1 and is provided with a base frame 8. A rotating rod 9 is provided inside the machine base 1. A pair of eccentric wheels 10 are provided on the rotating rod 9. The eccentric wheels 10 support the base frame 8 on the same side. A baffle 11 is provided on the eccentric wheels 10. The baffle 11 is located outside the base frame 8. An adjustment mechanism for adjusting the height of the pressure roller 2 is provided on the machine base 1.

[0019] In this embodiment, the machine base is also equipped with a processing mechanism. When the cardboard is fed to the processing mechanism using this device, the front end of the cardboard is first inserted into the gap between the pressure roller and the feeding roller. The pressure roller presses down on the cardboard, while the feeding motor drives the feeding roller to rotate, and the feeding roller feeds the cardboard to the processing mechanism.

[0020] During the cardboard feeding process, under the pre-compression of the pre-compression component, the pressure roller always maintains a downward pressure on the cardboard, which can prevent the cardboard from deviating during feeding and ensure stable feeding. In addition, the pressure roller is equipped with a pair of limiting components to limit the pressure roller and prevent it from moving left or right.

[0021] The limiting assembly includes a limiting frame rotatably mounted on the pressure roller shaft, the bottom of which extends into the machine base and is provided with the base frame. Figure 3-4 In the middle, the eccentric wheel supports the base frame on the same side, and the baffle is provided on the outer side of the eccentric wheel. Both baffles are located on the outer side of the left and right base frames. The base frame cannot move left or right under the obstruction and limitation of the left and right baffles, thereby preventing the pressure roller from moving left or right.

[0022] Figure 3 In the process, one end of the rotating rod 9 extends out of the machine base 1 and is provided with a gear 12. The adjustment mechanism includes a threaded sleeve 13 installed on the side wall of the machine base 1. A lead screw 14 is inserted into the threaded sleeve 13. The top of the lead screw 14 is provided with a rotating handle 15 and the bottom is provided with a straight rack 16. The straight rack 16 is installed with the gear 12 and is slidably installed on the machine base.

[0023] In practice, the actual height of the pressure roller can be slightly adjusted up and down to accommodate cardboard of different thicknesses, and the rotating rod passes through the eccentric positions of the pair of eccentric wheels. When it is necessary to adjust the height of the pressure roller, simply rotate the rotating handle. The rotating handle drives the lead screw to rotate, and the lead screw moves up and down within the lead sleeve. The rack moves up and down, and the rack drives the rotating rod to rotate through the gear. During the rotation of the rotating rod, the two eccentric wheels rotate simultaneously. As the eccentric wheels rotate, the base frame moves vertically by a small amount, and the pressure roller also moves up and down by a small amount, thus completing the adjustment of the pressure roller height.

[0024] In the above process, by adjusting the height of the pressure roller, the gap between the pressure roller and the feeding roller is changed, which facilitates the feeding of cardboard of different thicknesses. If thick cardboard needs to be fed, the height of the pressure roller is adjusted slightly, so that the gap between the pressure roller and the feeding roller is slightly larger, making it easier to insert the thick cardboard into the gap for feeding.

[0025] As a preferred structure, such as Figure 2 The pre-compression assembly includes a sliding sleeve 17 mounted on the fixed base 5, a sliding rod 18 inserted inside the sliding sleeve 17, a pressure plate 19 provided at the bottom of the sliding rod 18 facing the bearing 6, and a compression spring 20 provided on the sliding rod 18 between the pressure plate 19 and the sliding sleeve 17.

[0026] In this structure, the fixed base 5 has a fixed groove 21, in which the bearing is placed. The pressure roller is rotatably positioned between the two bearings, and a pre-pressing component is located on the fixed base opposite the bearing on the same side. In practice, with the limiting components on the left and right sides, the two ends of the pressure roller are confined within the fixed groove on the same side, and the bearing will not move left or right. Furthermore, under the action of the compression spring, regardless of whether the height of the pressure roller is adjusted upwards or downwards, the pressure plate always maintains a downward pressure on the bearing, ensuring that the pressure roller remains in contact with the cardboard during feeding.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
