Description

Technical Field

[0001] The utility model relates to the technical field of feeding devices, in particular to a feeding device for a plastic profile production line. Background Art

[0002] The feeding device for plastic plate processing is usually a belt feeding device. After working for a period of time, the transmission belt on the traditional plastic plate processing feeding device will produce permanent deformation and cause the belt to loosen, and then the friction will be insufficient and slip will occur, affecting the working ability of the belt transmission. At the same time, if the feeding device cannot accurately control the feeding speed, it may cause the production speed of plastic profiles to be unstable, resulting in low production efficiency or unstable product quality. If the transmission device or feeding roller in the feeding device has too much resistance, it may cause the motor load to be too large, increase energy consumption, and even damage the feeding device. Therefore, in response to the above problems, a feeding device for a plastic profile production line is proposed. Utility Model Content

[0014] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0015] Reference Figure 1As shown, the utility model provides an embodiment: a feeding device for a plastic profile production line, comprising a cutting machine 1, a pipe hole 2 is provided on the cutting machine 1, a rotating plate 3 is provided on the side of the cutting machine 1, the rotating plate 3 is an L-shaped telescopic structure, one end of the rotating plate 3 is connected to one side of the cutting machine 1 by a torsion spring, and the other end is connected to the fixed plate 4 by a torsion spring. When there is a plastic profile on the rotating plate 3, the torsion spring rotates under the action of gravity, and the plastic profile slides onto the slide plate 5, which does not cause a large amount of plastic profiles to accumulate and squeeze. The bottom surface of the rotating plate 3 is arranged below the pipe hole 2, so that the plastic profile can fall smoothly onto the rotating plate 3. A slide plate 5 is provided on the left side of the rotating plate 3, and the two slide plates 5 are symmetrical with respect to the center of the rotating plate 3. A rotating device 6 that can rotate and push the plastic profile is provided between the two slide plates 5. A plurality of rotating rods 7 are arranged horizontally on the same plane on the left side of the rotating device 6. The rotating rod 7 is connected between the two slide plates 5 by a motor. Two connecting rods 8 are provided at both ends of the outer side of the rotating rod 7. The rotating device 6 pushes the plastic profile that slides onto the slide plate 5 stably to the left, thereby ensuring the stability of the production speed.

[0016] Furthermore, the rotating device 6 includes a support rod 61, two support rods 61 are arranged between the two slides 5, a gear shaft 62 is arranged between the two support rods 61 and connected by a motor, a plurality of gears 63 of different diameters are arranged on the gear shaft 62, a plurality of gears 1 63 are meshed with a plurality of gears 2 64 of different diameters, and a plurality of gears 2 64 are connected through a rotating shaft 65, and both ends of the rotating shaft 65 are rotatably connected to the two slides 5, and the rotating shaft 65 is slidably arranged on the two slides 5 back and forth, and two sliding rods 66 are arranged on the outside of the rotating shaft 65, and the two sliding rods 66 are respectively arranged at the two ends of the rotating shaft 65, and the rotating shaft 65 slides on the slide 5 to change the mutual meshing of gears 1 63 and gear 2 64 of different diameters. When the rotation speed of the sliding rod 66 is changed, the speed at which plastic profiles of different lengths fall on the rotating plate 3 is different, so that the sliding rod 66 can adapt to the speed at which plastic profiles of different lengths slide to the slide 5, and will not cause the sliding rod 66 to idle or rotate less.

[0017] Furthermore, the distance between the center of the rotating rod 7 and the center of the rotating shaft 65 is less than the sum of the length of the connecting rod 8 and the length of the sliding rod 66, preventing the sliding rod 66 from pushing the plastic profile to the left and the connecting rod 8 from not being able to touch the plastic profile and transport the plastic profile. The connecting rod 8 and the sliding rod 66 are not in the same plane when rotating, preventing the connecting rod 8 and the sliding rod 66 from colliding with each other when rotating.

[0018] Furthermore, the length of the slide rod 66 and the length of the connecting rod 8 are both greater than the distance between the center of the rotating shaft 65 and the upper surface of the slide plate 5, so that the slide rod 66 and the connecting rod 8 can move the plastic profile that slides onto the slide plate 5 to the left, preventing the connecting rod 8 and the slide rod 66 from being unable to touch the plastic profile.

[0019] Furthermore, the diameters of the gear 1 63 and the gear 2 64 that mesh with each other are different, and when the rotating shaft 65 slides on the slide 5, only one set of corresponding gear 1 63 and gear 2 64 meshes with each other. The rotation speed of the slide bar 66 is changed by the mutual meshing of gear 1 63 and gear 2 64 of different diameters, and at the same time, it is prevented that the meshing of multiple sets of gear 1 63 and gear 2 64 causes inconsistent rotation speeds and causes damage.

[0020] Furthermore, the upper right surface of the skateboard 5 is an inclined surface sloping from the upper right to the lower left. When the rotating plate 3 rotates and the lower surface contacts the skateboard 5, the bottom surface of the rotating plate 3 and the inclined surface are in the same plane, so that the plastic profile slides smoothly onto the skateboard 5 without causing the plastic profile to tilt or bump.

[0021] Working principle: When transporting plastic profiles, the staff first adjusts the length of the rotating plate 3 according to the required length of the plastic profile, and selects gear 1 63 and gear 2 64 of appropriate diameter according to the cutting time of a plastic profile. When the plastic profile is moved out of the pipe hole 2 and cut by the cutting machine 1, the plastic profile falls onto the rotating plate 3. At this time, the rotating plate 3 is subjected to gravity to cause the torsion spring to rotate the rotating plate 3 and tilt the plastic profile, and the plastic profile slides onto the slide plate 5. The gear shaft 62 rotates under the drive of the motor and drives gear 1 63 to rotate. The rotation of gear 1 63 drives the meshing gear 2 64 to rotate, and drives the rotating shaft 65 and the slide bar 66 to rotate. The slide bar 66 touches the plastic profile and pushes the plastic profile to the left. Then the rotating rod 7 rotates under the drive of the motor and drives the connecting rod 8 to rotate. The connecting rod 8 continues to push the plastic profile to the left, and the slide bar 66 continues to rotate and pushes the next plastic profile.

[0022] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
