Description

Technical Field

[0001] This utility model belongs to the field of PVC pipe production technology, and in particular relates to a quantitative feeding device for auxiliary materials in PVC drainage pipe production. Background Technology

[0002] PVC drainage pipes are a common material for building water supply and drainage. During their production, various auxiliary materials (such as calcium carbonate filler, color masterbatch, and impact modifiers) need to be added to improve the physical properties or appearance of the pipes. The feeding process of these auxiliary materials directly affects the quality stability of the pipes—fluctuations in the feeding speed or material agglomeration can lead to uneven mixing, deviations in pipe wall thickness, or surface defects.

[0003] In existing technologies, PVC drainage pipe auxiliary materials are mostly fed using screw conveyors or vibrating feeders. While screw conveyors can achieve continuous conveying, they are prone to agglomeration due to material friction and adhesion, leading to uneven discharge. Vibrating feeders rely on mechanical vibration to control the material feed rate, and unstable vibration frequencies can easily result in "pulsating" feeding, affecting the uniformity of subsequent mixing processes. In addition, existing equipment lacks a pretreatment structure for lumpy materials, requiring additional crushing equipment, which increases production costs and process complexity.

[0004] To address this issue, we provide a quantitative feeding device for auxiliary materials used in the production of PVC drainage pipes. Utility Model Content

[0005] The purpose of this utility model is to provide a quantitative feeding device for PVC drainage pipe production auxiliary materials. Through the cooperation of the pressing mechanism and the dispersing mechanism, the problem of easy material blockage and clumping in the existing quantitative feeding device for PVC drainage pipe production auxiliary materials is solved.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a quantitative feeding device for auxiliary materials in PVC drainage pipe production, comprising a box body, a feeding funnel at the top of the box body, a feeding pipe at the bottom of the box body, and a feeding tray inside the box body; a pressing mechanism is provided inside the feeding funnel, the pressing mechanism comprising a protective box fixedly connected inside the feeding funnel, a turntable disposed inside the protective box, a guide post fixedly connected to one side of the turntable, a sliding frame slidably connected to the surface of the guide post, and a pressing block fixedly connected to the bottom of the sliding frame; a dispersing mechanism is provided inside the box body, the dispersing mechanism comprising a stirring rod rotatably connected to the surface of the feeding tray via a bearing seat, a first gear fixedly connected to the surface of the stirring rod, and a toothed ring meshing with the surface of the first gear.

[0008] The present invention is further configured such that a drive motor is fixedly connected to the top of the housing, a semi-gear is fixedly connected to the output shaft of the drive motor, and a second gear meshes with the surface of the semi-gear.

[0009] The present invention is further configured such that the shaft of the second gear is fixedly connected to the top of the feeding tray. The output shaft of the drive motor drives the semi-gear to rotate, and the semi-gear drives the feeding tray to rotate through the second gear. Each rotation of the semi-gear drives the second gear to rotate 90 degrees, causing the feeding tray to rotate intermittently, so that the feeding trough is precisely aligned with the feeding tube.

[0010] The present invention is further configured such that a first bevel gear is fixedly connected to the output shaft of the drive motor, and a second bevel gear meshes with the surface of the first bevel gear.

[0011] The present invention is further configured such that a rotating shaft is fixedly connected to the center of the second bevel gear shaft, one end of the rotating shaft is fixedly connected to the center of the turntable shaft, and the drive motor synchronously drives the pressing mechanism and the feeding plate. Power is transmitted through the bevel gear reversal at ninety degrees, which reduces energy consumption and ensures the coordination of actions.

[0012] The present invention is further configured such that a feeding groove is provided on the top of the feeding tray, and the number of the feeding grooves is four.

[0013] The present invention is further configured such that an electric push rod is fixedly connected to the bottom of the feeding tray, and a baffle is fixedly connected to the output end of the electric push rod. The baffle normally covers the bottom of the feeding trough. When material is placed in the feeding trough and rotates to the top of the feeding pipe, the corresponding electric push rod extends and retracts to drive the baffle to move, thereby realizing quantitative feeding.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model effectively compacts the accumulated material in the feeding hopper through the periodic pressing action of the pressing mechanism, destroys the bridging effect between materials, avoids blockage caused by material adhesion, and ensures that the auxiliary materials continuously and stably enter the feeding tray. When the feeding tray rotates, the stirring rod of the dispersing mechanism generates radial rotational force through meshing with the toothed ring, which shears and crushes the auxiliary materials in the feeding trough, breaks up the lumpy materials, improves the dispersion and uniformity of the auxiliary materials, and prevents lumps from entering subsequent processes and affecting product quality.

[0016] 2. The feeding tray of this utility model achieves 90-degree step rotation through the intermittent meshing of the half-gear and the second gear. Combined with the precise control of the baffle by the bottom electric push rod, the material in each feeding trough can be quantitatively dropped into the feeding pipe, realizing precise control of the feeding amount and meeting the stability requirements of auxiliary material addition in the production process of PVC drainage pipe. The drive motor synchronously drives the pressing mechanism and the feeding tray through the bevel gear set, realizing the integrated transmission of power, reducing the need for additional power sources, reducing energy consumption. At the same time, the action sequence of each mechanism is controlled by the same motor, improving the coordination and reliability of the device operation.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of the present invention will be described below with reference to the accompanying drawings of the embodiments of the present invention. The described embodiments are only some embodiments of the present invention, and not all embodiments.

[0026] Example 1

[0027] Please see Figures 1-5 This utility model is a quantitative feeding device for auxiliary materials in PVC drainage pipe production, including a box body 1, a feeding funnel 2 at the top of the box body 1, a feeding pipe 3 at the bottom of the box body 1, and a feeding tray 4 in the inner cavity of the box body 1; a pressing mechanism is provided in the inner cavity of the feeding funnel 2, the pressing mechanism includes a protective box 5 fixedly connected inside the feeding funnel 2, a turntable 6 set in the inner cavity of the protective box 5, a guide post 7 fixedly connected to one side of the turntable 6, a sliding frame 8 slidably connected to the surface of the guide post 7, and a pressing block 9 fixedly connected to the bottom of the sliding frame 8; a dispersing mechanism is provided in the inner cavity of the box body 1, the dispersing mechanism includes a stirring rod 10 rotatably connected to the surface of the feeding tray 4 through a bearing seat, a first gear 11 fixedly connected to the surface of the stirring rod 10, and a toothed ring 12 meshing with the surface of the first gear 11.

[0028] Further details: The protective box 5 is fixed to the inner wall of the feeding hopper 2. The turntable 6 is installed inside the protective box 5 through the rotating shaft 18. The guide column 7 is vertically fixed to the eccentric position of the turntable 6. The sliding frame 8 is sleeved on the surface of the guide column 7 to form a sliding pair. The lower pressure block 9 is fixed to the bottom of the sliding frame 8. The rotation of the turntable 6 drives the guide column 7 to move in a circular motion. The rotational motion is converted into the linear reciprocating motion of the lower pressure block 9 through the sliding frame 8, which forcibly compacts and clears the bridging material, ensuring that the auxiliary material continuously enters the feeding trough 19. The toothed ring 12 is fixed to the inner wall of the box 1 and meshes with the first gear 11. When the feeding plate 4 rotates, the fixed toothed ring 12 drives the first gear 11 to rotate, which drives the stirring rod 10 to centrifugally disperse the auxiliary material in the feeding trough 19 and break up the clumps.

[0029] Example 2

[0030] Please see Figures 1-5 Based on embodiment 1, a drive motor 13 is fixedly connected to the top of the housing 1, a semi-gear 14 is fixedly connected to the output shaft of the drive motor 13, a second gear 15 meshes with the surface of the semi-gear 14, the shaft of the second gear 15 is fixedly connected to the top of the feeding tray 4, a first bevel gear 16 is fixedly connected to the output shaft of the drive motor 13, a second bevel gear 17 meshes with the surface of the first bevel gear 16, a rotating shaft 18 is fixedly connected to the shaft of the second bevel gear 17, one end of the rotating shaft 18 is fixedly connected to the shaft of the turntable 6, a feeding groove 19 is opened on the top of the feeding tray 4, the number of feeding grooves 19 is four, an electric push rod 20 is fixedly connected to the bottom of the feeding tray 4, and a baffle 21 is fixedly connected to the output end of the electric push rod 20.

[0031] Further details: The output shaft of the drive motor 13 drives the semi-gear 14 to rotate. The semi-gear 14 drives the feeding disc 4 to rotate through the second gear 15. Every time the semi-gear 14 rotates, it drives the second gear 15 to rotate 90 degrees, causing the feeding disc 4 to rotate intermittently, so that the feeding trough 19 is precisely aligned with the feeding pipe 3. The baffle 21 normally covers the bottom of the feeding trough 19. When the feeding trough 19 is placed with material and rotates above the feeding pipe 3, the corresponding electric push rod 20 extends and retracts, driving the baffle 21 to move, realizing quantitative feeding. The drive motor 13 synchronously drives the pressing mechanism and the feeding disc 4, and transmits power through the 90-degree reversal of the bevel gear, reducing energy consumption and ensuring the coordination of actions.

[0032] The working principle of this utility model is as follows: the auxiliary material is added from the top of the feeding funnel 2, the drive motor 13 is started, the semi-gear 14 starts to rotate, when the teeth of the semi-gear 14 mesh with the second gear 15 of the feeding disc 4, the feeding disc 4 rotates, and when the semi-gear 14 disengages, the feeding disc 4 stops.

[0033] During this process, the semi-shaft gear 14 simultaneously drives the first bevel gear 16 to rotate, which in turn drives the turntable 6 to rotate via the second bevel gear 17 and the rotating shaft 18. The eccentric block on the edge of the turntable 6 pushes the sliding frame 8 to slide up and down along the guide post 7. The pressing block 9 periodically presses down the material in the feeding hopper 2, pushing the accumulated material into the feeding trough 19 of the feeding tray 4 to avoid arch bridge blockage.

[0034] When the feeding disc 4 rotates, the stirring rod 10 fixed at its bottom rotates synchronously. The first gear 11 on the surface of the stirring rod 10 meshes with the toothed ring 12 on the inner side wall of the box 1, generating radial rotation. This shears and tumbles the material on the upper surface of the feeding disc 4, breaking up the lumpy material into fine particles, ensuring that the material falls loosely into the feeding trough 19. When the feeding trough 19, which contains material, rotates above the feeding pipe 3, the corresponding electric push rod 20 extends and retracts, driving the baffle 21 to move, ultimately achieving stable and uniform feeding.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
