Description

Technical Field

[0001] This utility model relates to the field of plastic processing equipment technology, specifically a precision positioning feeding mechanism for plastic processing equipment. Background Technology

[0002] Plastic processing equipment is a device that melts and molds plastics, and can process plastics into plastic parts of various shapes. Plastic parts are diverse in industrial production and are essential components, characterized by irregular shapes, good flexibility and one-piece molding.

[0003] Feeders are used in the production of plastic parts, such as the existing 12-station rotary automatic plastic parts feeder. Inside the feeder, there are multiple sets of positioning rods for placing plastic parts. These positioning rods are arranged in a circular array outside the rotating disk. Plastic parts can be placed outside the positioning rods. When moving the feeder, external suction cups, controlled by the drive assembly, can suction and move the plastic parts to achieve feeding. In existing products, the positioning rods are fixed to the outside of the rotating disk using fixing plates and bolts. Installing multiple sets of fixing plates requires a large number of bolts and clamps for securing them. When changing to plastic parts of different sizes, the fixing plates need to be disassembled and replaced with another set of positioning rods, and then secured again with multiple sets of fasteners, making installation quite cumbersome.

[0004] To address these issues, we offer a precision positioning feeding mechanism for plastic processing equipment. Utility Model Content

[0005] 1) Technical problems to be solved

[0006] This utility model proposes a precision positioning feeding mechanism for plastic processing equipment, which solves the problem of the relatively troublesome replacement of the positioning rod through the cooperation between the pressure plate, the conical cylinder and the spring.

[0007] (ii) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a precision positioning feeding mechanism for plastic processing equipment, including a worktable, a fixed shaft installed inside the worktable, and a rotating disk detachably connected to the outer surface of the fixed shaft;

[0009] A mounting plate is slidably connected to the outer surface of the rotating disk. A limit rod is fixedly installed on the outer surface of the mounting plate. A fixing plate is fixedly installed at one end of the limit rod. A positioning rod is fixedly installed on the outer surface of the fixing plate. A plastic part is sleeved on the outside of the positioning rod. A connecting rod is threaded inside the mounting plate. A tapered cylinder and a spring are respectively sleeved on the outside of the connecting rod.

[0010] The rotating disk is rotatably connected to a rotating rod inside. A fixing ring is fixedly installed on the outer surface of the rotating rod. A support rod is fixedly installed on the outer surface of the fixing ring. A pressure plate is detachably connected to the outer surface of the support rod.

[0011] Furthermore, the rotating disk has multiple sets of fixing holes inside, and the outer surface of the limiting rod is slidably connected to the inside of the fixing holes. The fixing holes and the limiting rod are arranged in a circular array inside the rotating disk.

[0012] Furthermore, a pad is fitted over the positioning rod, the plastic part is placed on the outside of the pad, and the inside of the pad is hollow.

[0013] Furthermore, one end of the spring contacts the outer surface of the mounting plate, and the other end of the spring contacts the lower surface of the conical cylinder.

[0014] Furthermore, the inclined surface of the conical cylinder faces upward, and the pressure plate has an inclined surface on its downward-facing side, with the inclined surface of the pressure plate in contact with the inclined surface of the conical cylinder.

[0015] Furthermore, the fixed ring is internally slidably connected with fixed bolts arranged in a ring array, and the outer surface of the fixed bolts is connected to the internal thread of the rotating disk.

[0016] Furthermore, a drive assembly is mounted on the outside of the workbench, a mounting bracket is mounted on the outside of the drive assembly, an electric push rod is mounted on the outside of the mounting bracket, and a movable plate is detachably connected to the output end of the electric push rod.

[0017] (iii) Beneficial effects:

[0018] Compared with existing technologies, the precision positioning feeding mechanism of this plastic processing equipment has the following advantages:

[0019] 1. This plastic processing equipment uses a precision positioning feeding mechanism. Through the cooperation of pressure plates, conical cylinders, and springs, multiple sets of mounting plates are placed outside the rotating disk when installing positioning rods. Then, the movement of multiple sets of support rods and pressure plates is controlled by a rotating ring. The compression of the conical cylinder by multiple sets of pressure plates can limit the vertical position of the conical cylinder. The pressure applied to the conical cylinder by the springs facilitates the connection of pressure plates and conical cylinders with different processing precisions. It has wider applicability, better fixing effect, and can quickly fix and disassemble multiple sets of positioning rods at the same time. It realizes the function of quickly fixing multiple sets of fixing plates and positioning rods, which is beneficial for quickly changing positioning rods according to the size of different plastic parts.

[0020] Second, this plastic processing equipment uses a precision positioning feeding mechanism. By setting up limit rods and fixing bolts, multiple sets of limit rods can limit the horizontal position of the mounting plate after being inserted into the fixing hole. This, combined with the vertical fixing effect of the pressure plate, improves the stability of the fixing ring when the pressure plate presses down on the conical cylinder.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0029] The motor and electric push rod in this utility model are common electrical and hydraulic devices in the prior art, and this application will not elaborate on their models or internal structures.

[0030] like Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a precision positioning feeding mechanism for plastic processing equipment, including a worktable 1, a fixed shaft 2 installed inside the worktable 1, a rotating disk 3 detachably connected to the outer surface of the fixed shaft 2, a rotary motor installed inside the worktable 1, which can control the rotation of the rotating disk 3, and the area above the rotating disk 3 is divided into 12 working areas. Each rotation of the rotary motor can move a group of working areas to the feeding area, which is accomplished by the cooperation of components such as point and position sensors.

[0031] A mounting plate 4 is slidably connected to the outer surface of the rotating disk 3. A limiting rod 5 is fixedly installed on the outer surface of the mounting plate 4. Multiple sets of fixing holes 16 are opened inside the rotating disk 3. The outer surface of the limiting rod 5 is slidably connected to the inside of the fixing holes 16. The fixing holes 16 and the limiting rod 5 are arranged in a circular array inside the rotating disk 3. Each working area is positioned by two sets of fixing holes 16 and limiting rod 5, which can quickly position the vertical position of the mounting plate 4.

[0032] A fixing plate 6 is fixedly installed at one end of the limiting rod 5. A positioning rod 7 is fixedly installed on the outer surface of the fixing plate 6. A plastic part 8 is sleeved on the outside of the positioning rod 7. A pad 17 is sleeved on the outside of the positioning rod 7. The plastic part 8 is placed on the outside of the pad 17. The inside of the pad 17 is hollow. Multiple sets of positioning rods 7 can be arranged in different shapes around the outside of the fixing plate 6. Different positioning rods 7 with different structures can be selected according to the different shapes of plastic parts 8. When feeding, the plastic part 8 is placed on the outside of the positioning rod 7 for limiting. The pad 17 is made of rigid plastic plate and mainly serves to move the plastic part 8 up and down outside the positioning rod 7.

[0033] A drive assembly 19 is mounted on the outside of the workbench 1. A mounting frame 20 is mounted on the outside of the drive assembly 19. An electric push rod 21 is mounted on the outside of the mounting frame 20. A movable plate 22 is detachably connected to the output end of the electric push rod 21. The drive assembly 19 is mainly composed of a motor and a threaded rod. The mounting frame 20 is threadedly connected to the threaded rod. The rotation of the threaded rod can control the up and down movement of the mounting frame 20. When a set of plastic parts 8 moves up and down, the movable plate 22 is pushed into the hole inside the pad 17 by the electric push rod 21. Then, the plastic parts 8 are moved by the movement of the mounting frame 20, which facilitates the top suction of external suction cups and other components.

[0034] The mounting plate 4 has an internal threaded connection to a connecting rod 9. A conical cylinder 10 and a spring 11 are respectively fitted on the outside of the connecting rod 9. The inclined surface of the conical cylinder 10 faces upward. One end of the spring 11 contacts the outer surface of the mounting plate 4, and the other end of the spring 11 contacts the lower surface of the conical cylinder 10. The threaded connecting rod 9 can quickly fix the conical cylinder 10 and the spring 11. A baffle is installed at one end of the connecting rod 9 to limit the position of the conical cylinder 10. The spring 11 can apply an upward force to the conical cylinder 10.

[0035] The rotating disk 3 is internally connected to a rotating rod 12. A fixing ring 13 is fixedly installed on the outer surface of the rotating rod 12. Fixing bolts 18 are slidably connected inside the fixing ring 13 and arranged in a ring array. The outer surface of the fixing bolts 18 is threadedly connected to the inside of the rotating disk 3. The fixing ring 13 can rotate circumferentially under the action of the rotating rod 12. The position of the fixing ring 13 can be stably fixed by the threaded connection between one end of the fixing bolts 18 and the inside of the rotating disk 3. Multiple sets of fixing bolts 18 are provided to improve the stability during fixing.

[0036] A support rod 14 is fixedly installed on the outer surface of the fixing ring 13. A pressure plate 15 is detachably connected to the outer surface of the support rod 14. The pressure plate 15 has an inclined surface on the downward side. The inclined surface of the pressure plate 15 is in contact with the inclined surface of the conical cylinder 10. When the limiting rod 5 is placed, the fixing ring 13 is rotated. At this time, the support rod 14 drives the pressure plate 15 to contact the inclined surface of the conical cylinder 10. Through the mutual compression of the two sets of inclined surfaces and the elastic force of the spring 11, the upper and lower positions of the mounting plate 4 can be limited. The setting of the spring 11 ensures that the pressure plate 15 and the conical cylinder 10 can be synchronously fixed even if there are processing errors. At this time, the mounting plate 4 needs to overcome the elastic force of the spring 11 to move, realizing the function of quickly fixing multiple sets of positioning rods 7. Conversely, it can quickly disassemble multiple sets of positioning rods 7.

[0037] Working principle: During installation, the limiting rod 5 is inserted into the fixing hole 16, and the fixing ring 13 is rotated to bring the pressure plate 15 close to the conical cylinder 10. When the conical cylinder 10 moves, it will press down on the inclined surface of the conical cylinder 10. At this time, the mounting plate 4 can be quickly fixed by the elastic force of the spring 11 and the downward pressure of the pressure plate 15, realizing the function of quickly fixing multiple sets of positioning rods 7. Conversely, multiple sets of positioning rods 7 can be quickly disassembled.

[0038] During loading, the moving plate 22 moves into the interior of a set of pads 17, and moves under the control of the drive assembly 19 to push the plastic part 8 to move and achieve loading.
