Description

Technical Field

[0001] This utility model belongs to the field of pulp molding equipment, specifically relating to a pulp molding press. Background Technology

[0002] Pulp molding presses are automated and environmentally friendly production equipment, mainly used to convert waste paper and other raw materials into biodegradable pulp molded products. In existing pulp molding equipment, hot pressing forming machines and edge trimming machines often use a crankshaft connecting rod mechanism as the pressure generating mechanism. During downward and upward pressing, the pressure of the crankshaft connecting rod mechanism on the four guide pillars constantly changes, and the force-bearing surface between the guide sleeve and the guide pillar is limited to the contact surface, causing localized wear on the guide sleeve. This results in a significant workload for maintenance. Furthermore, using a crankshaft connecting rod mechanism requires the motor to frequently rotate forward and reverse, which causes considerable damage to the motor and braking device. Therefore, to avoid the shortcomings of existing technology, it is necessary to improve it. Utility Model Content

[0003] The purpose of this invention is to provide a pulp molding press that enables the motor to run continuously, avoiding frequent forward and reverse rotations and frequent braking, thereby reducing wear.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A pulp molding press includes a frame, a sliding seat, a camshaft, and a geared motor. The inner wall of the frame is provided with several guide plates forming a vertically arranged guide channel. A lower mold mounting plate is provided below the guide channel. The sliding seat is slidably mounted on the guide channel and can slide up and down along it. An upper mold mounting plate is connected below the sliding seat. The camshaft is rotatably mounted on the frame, passes through the sliding seat, and drives it to slide up and down along the guide channel. A first cam is provided in the middle of the camshaft, and second cams are provided on its left and right sides respectively. A rolling wheel is rotatably mounted inside the sliding seat, and the rolling wheel abuts against the second cams. The geared motor is fixed to the frame, and its output end is connected to the camshaft and can drive the sliding seat to slide up and down along the guide channel.

[0006] As a preferred embodiment of the above-mentioned pulp molding press, a pressure roller mechanism is provided on the top of the frame. The pressure roller mechanism includes a hydraulic cylinder, a first pressure roller, and a pressure roller bracket. The hydraulic cylinder is mounted on the pressure roller bracket. The output end of the hydraulic cylinder is connected to the first pressure roller and provides downward pressure to the first pressure roller. The first pressure roller extends into the sliding seat and abuts against the first cam.

[0007] As a preferred embodiment of the aforementioned pulp molding press, the first cam and the second cam have opposite convex directions.

[0008] As a preferred embodiment of the aforementioned pulp molding press, the hydraulic cylinder is driven by a controller to keep the first pressure roller in a contacting state during the rotation of the first cam.

[0009] As a preferred embodiment of the above-mentioned pulp molding press, the camshaft is fixedly connected to a brake disc on the outside of the frame, and a hydraulic brake that cooperates with the brake disc is provided on the frame, the hydraulic brake being able to clamp the brake disc.

[0010] As a preferred embodiment of the above-mentioned pulp molding press, the sliding seat is provided with rolling wheels on both the upper and lower sides of each second cam, the camshaft is provided with two second cams, and the sliding seat is provided with four rolling wheels accordingly.

[0011] As a preferred embodiment of the aforementioned pulp molding press, the output end of the geared motor is connected to a transition gear, and a driven gear is connected to the camshaft, wherein the transition gear meshes with the driven gear.

[0012] As a preferred embodiment of the aforementioned pulp molding press, there are eight guide plates, which are respectively disposed at the four corners of the inner wall of the frame.

[0013] The advantages of implementing the pulp molding press provided by this utility model compared with the prior art are as follows:

[0014] The present invention features a geared motor connected to a camshaft drive. The geared motor drives the camshaft to rotate, while the sliding seat is slidably positioned within a guide channel enclosed by a guide plate. Driven by the rotation of the camshaft, it moves up and down along the guide channel. During the rotation of the camshaft, the second cam rotates relative to the rolling wheel. The pressure applied by the second cam to the rolling wheel is perpendicular to the contact surface. Therefore, when the second cam rotates to the lower side of the camshaft, it applies downward pressure to the rolling wheel, causing the mold mounted on the upper mold mounting plate below the sliding seat to close with the mold mounted on the lower mold mounting plate, applying pressure to mold the pulp. When the second cam rotates to the upper side of the camshaft, it applies upward support force to the rolling wheel, driving the sliding seat to move upward. The continuous rotation of the camshaft molds the pulp. Since the rolling wheel can rotate relative to the second cam when the camshaft rotates, the camshaft only drives the sliding seat to move up and down, reducing wear on the side guide plate. The camshaft only needs to rotate continuously to drive the sliding seat to slide up and down along the guide channel, allowing the motor to run continuously and avoiding frequent forward and reverse rotation and frequent braking.

[0029] Please refer to the following: Figures 1 to 7 The pulp molding press provided in the embodiments of this utility model will now be described.

[0030] like Figures 1 to 7 As shown, the pulp molding press of this utility model includes a frame 100, a sliding seat 300, a camshaft 200, and a reduction motor 110. The inner wall of the frame 100 is provided with several guide plates 130, which form a vertically arranged guide channel 140. A lower mold mounting plate 410 is provided below the guide channel 140. The sliding seat 300 is slidably disposed on the guide channel 140 and can slide up and down along the guide channel 140. An upper mold mounting plate 400 is connected below the sliding seat 300. The camshaft 200 is rotatably mounted on the frame 100. A camshaft 200 passes through the sliding seat 300 and can drive the sliding seat 300 to slide up and down along the guide channel 140. A first cam 220 is provided in the middle of the camshaft 200, and second cams 230 are provided on the left and right sides of the camshaft 200 respectively. A rolling wheel 310 is rotatably installed inside the sliding seat 300. The rolling wheel 310 abuts against the second cam 230. The reduction motor 110 is fixed on the frame 100. The output end of the reduction motor 110 is connected to the camshaft 200 and can drive the sliding seat 300 to slide up and down along the guide channel 140.

[0031] When the camshaft 200 rotates, the roller 310 abuts against the second cam 230 and rotates relative to it, thereby preventing the second cam 230 from exerting lateral pressure on the slide seat 300 and squeezing the guide plate 130, causing wear on the guide plate 130.

[0032] The upper mold mounting plate 400 and the lower mold mounting plate 410 are used to install molds for molding pulp.

[0033] For example, a pressure roller mechanism 600 is provided on the top of the frame 100. The pressure roller mechanism 600 includes a hydraulic cylinder 610, a first pressure roller 620 and a pressure roller bracket 630. The hydraulic cylinder 610 is disposed on the pressure roller bracket 630. The output end of the hydraulic cylinder 610 is connected to the first pressure roller 620 and provides downward pressure to the first pressure roller 620. The first pressure roller 620 extends into the sliding seat 300 and abuts against the first cam 220. During the rotation of the camshaft 200, when the second cam 230 rotates to the lower side of the camshaft 200, it exerts downward pressure on the sliding seat 300, causing the mold on the upper mold mounting plate 400 to close with the mold on the lower mold mounting plate 410. When the second cam 230 applies downward pressure to the sliding seat 300, it will also receive a reaction force from the sliding seat 300. Therefore, the camshaft 200 will be subjected to force at both ends. In order to avoid the camshaft 200 being easily deformed due to only being subjected to force at both ends, the output end of the cylinder 610 of the pressure roller mechanism 600 is connected to the first pressure roller 620 and provides downward pressure to the first pressure roller 620, so that the first pressure roller 620 abuts and presses against the first cam 220, so that the force on the middle and both ends of the camshaft 200 is balanced, avoiding the deformation and bending of the camshaft 200 due to only being subjected to force at both ends, and extending the service life of the camshaft 200.

[0034] For example, the protrusions of the first cam 220 and the second cam 230 are in opposite directions. This design allows the first cam 220 and the second cam 230 to rotate with opposite protrusion directions. When the protrusion of the second cam 230 rotates to the downward position, the protrusion of the first cam 220 faces upward and tightly abuts against the first pressure roller 620, receiving the pressure of the first pressure roller 620 to balance the force on the camshaft 200 and prevent deformation.

[0035] For example, the hydraulic cylinder 610 is driven by the controller to keep the first pressure roller 620 in a contact state during the rotation of the first cam 220. When the protruding part of the first cam 220 rotates to the downward position, it can still abut against the camshaft 200, preventing the two ends of the camshaft 200 from being deformed by the weight of the sliding seat 300.

[0036] For example, a brake disc 510 is fixedly connected to the outside of the frame 100 on the camshaft 200. A hydraulic brake 500 is provided on the frame 100 to cooperate with the brake disc 510. The hydraulic brake 500 can clamp the brake disc 510. When an emergency stop brake is required, the camshaft 200 is stopped from rotating by activating the hydraulic brake 500 to clamp the brake disc 510.

[0037] For example, the sliding seat 300 is provided with rolling wheels 310 on both the upper and lower sides of each second cam 230, the camshaft 200 is provided with two second cams 230, and the sliding seat 300 is provided with four rolling wheels 310 accordingly. The rolling wheels 310 are provided on both the upper and lower sides of the second cam 230, respectively, and rotate relative to the second cam 230 when the second cam 230 rotates to the upper and lower sides of the camshaft 200, driving the sliding seat 300 to move in the vertical direction along the guide channel 140, reducing the squeezing force on the side and reducing the wear of the guide plate 130.

[0038] For example, the output end of the geared motor 110 is connected to a transition gear 120, and a driven gear 210 is connected to the camshaft 200. The transition gear 120 meshes with the driven gear 210. The geared motor 110 drives the camshaft 200 to rotate through the transmission action of the transition gear 120 and the driven gear 210. Moreover, the transition gear 120 and the driven gear 210 are set with different gear ratios to achieve a speed reduction effect and increase the output torque.

[0039] For example, there are eight guide plates 130, which are respectively disposed at the four corners of the inner wall of the frame 100. Two guide plates 130 are disposed on each of the four surfaces of the inner wall of the frame 100, so that a gap is left between the two guide plates 130 to allow the camshaft 200 to extend out of the frame 100 and connect with the driven gear 210 and the brake disc 510.

[0040] The advantages of implementing the pulp molding press provided by this utility model compared with the prior art are as follows:

[0041] In this invention, the geared motor 110 is connected to the camshaft 200 for transmission. The geared motor 110 drives the camshaft 200 to rotate. The sliding seat 300 is slidably disposed within the guide channel 140 formed by the guide plate 130. Driven by the rotation of the camshaft 200, it moves up and down along the guide channel 140. During the rotation of the camshaft 200, the second cam 230 rotates relative to the rolling wheel 310. The pressure applied by the second cam 230 to the rolling wheel 310 is perpendicular to the contact surface. Therefore, when the second cam 230 rotates to the lower side of the camshaft 200, it applies downward pressure to the rolling wheel 310, thereby causing the mold mounted on the upper mold mounting plate 400 below the sliding seat 300 to move back and forth with the lower mold mounting plate 400. The mold installed on the 10 is closed, and pressure is applied to mold the pulp. When the second cam 230 rotates to the upper side of the camshaft 200, it applies an upward supporting force to the rolling wheel 310, driving the sliding seat 300 to move upward. The pulp is molded by the continuous rotation of the camshaft 200. Since the rolling wheel 310 can rotate relative to the second cam 230 when the camshaft 200 rotates, the camshaft 200 only drives the sliding seat 300 to move up and down, reducing the wear on the side guide plate 130. The camshaft 200 only needs to rotate continuously to drive the sliding seat 300 to slide up and down along the guide channel 140, so that the motor can run continuously and avoid frequent forward and reverse rotation and frequent braking.

[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
