Description

Technical Field

[0001] This utility model relates to the field of rubber parts production technology, specifically to an extrusion molding machine for producing rubber parts with rapid material feeding. Background Technology

[0002] Rubber extrusion molding involves heating and plasticizing the rubber compound in an extruder, subjecting it to intense shearing between the screw and barrel, and then continuously conveying it forward through the rotation of the screw. Under specific pressure, the rubber compound is extruded through an extrusion die (also known as a die) to obtain the desired product shape.

[0003] The prior art (Chinese Patent No. CN221112766U, Publication Date: 2024-06-11) discloses a single-screw extruder for rubber parts production, comprising an extruder body and a hopper. The extruder body has a feed inlet, and the lower end of the hopper has a discharge pipe. The lower end of the discharge pipe is bent outwards to form a connecting end, which is fixedly connected to the feed inlet of the extruder body by bolts. A support arm is fixed outwards from the hopper, and a column is provided on one side of the extruder body. A sliding hole is provided through the support arm, which slides in conjunction with the column. A counterweight is fixed to the other end of the support arm. This single-screw extruder for rubber parts production has the advantages of easy disassembly and installation, convenient unblocking, and high efficiency.

[0004] While existing technology facilitates disassembly and installation, it cannot assist the rubber in the hopper to enter the screw extrusion barrel during use. The rubber has a certain degree of stickiness and may adhere to the inner wall of the hopper, resulting in a relatively slow process and affecting the molding of rubber parts.

[0005] Therefore, we propose an extrusion molding machine for producing rubber parts with rapid material feeding to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide an extrusion molding machine for producing rubber parts that can quickly feed materials, in order to solve the problem mentioned in the background art that the rubber in the hopper cannot be assisted to enter the spiral extrusion barrel, and that the rubber has a certain degree of stickiness and may stick to the inner wall of the hopper, resulting in slow feeding and affecting the molding of rubber parts.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an extrusion molding machine for producing rubber parts with rapid feeding capability, comprising a housing, a first motor fixedly connected to the outer side of the housing, and a spiral extrusion rod provided inside the housing, a feeding box penetrating through the upper surface of the housing, a fixing plate fixedly connected to the upper side of the feeding box, and an auxiliary mechanism for assisting rapid rubber feeding provided on the fixing plate.

[0008] Furthermore, the spiral extrusion rod is nested inside the housing, and two sets of spiral extrusion rods are symmetrically arranged about the inside of the housing, with gears fixedly connected to the ends of both sets of spiral extrusion rods.

[0009] Furthermore, the output end of the first motor is fixedly connected to the end side of a set of spiral extrusion rods, and the two sets of gears mesh with each other.

[0010] Furthermore, the auxiliary mechanism includes a second motor, a lead screw is fixedly connected to the output end of the second motor, and the other end of the lead screw is nested and connected to a fixed plate. A fixed shaft is fixedly connected to the side of the fixed plate. A linkage plate is threadedly connected to the outer side of the lead screw, and an abutment rod is fixedly connected to the outer end of the linkage plate. A striking rod is nested and connected to the outer side of the fixed shaft, and an abutment groove is provided at the upper end of the striking rod. The abutment rod is nested and connected inside the abutment groove.

[0011] Furthermore, the linkage plate drives the contact rod and the contact groove to form a sliding structure, and the striking rod forms a rotating structure with the fixed shaft through the contact rod, and the striking rod is symmetrically distributed about the center point of the fixed plate.

[0012] Furthermore, the fixed plate is provided with a sliding groove, and a slider is nested inside the sliding groove. The upper end of the slider is fixedly connected to the lower surface of the linkage plate, and a stirring rod is fixedly connected to the lower surface of the slider.

[0013] Furthermore, the slider forms a sliding structure with the sliding groove via a linkage plate, and the lower end of the stirring rod extends into the interior of the feeding box.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Rubber can be fed into the housing through the feeding box. At this time, the first motor is started, which will drive the spiral extrusion rod on one side to rotate synchronously. The spiral extrusion rod can drive the gear to rotate synchronously. At this time, the two sets of spiral extrusion rods can be driven to rotate synchronously under the meshing action of the gear, thereby performing the rubber extrusion operation.

[0016] 2. After the rubber is fed into the feeding box, the second motor can be started, and the auxiliary mechanism can be driven to run. The auxiliary mechanism can accelerate the speed at which the rubber is fed into the shell from the feeding box, thereby further improving the extrusion effect of the rubber parts.

[0017] After the second motor starts, it can drive the lead screw to rotate. At this time, the lead screw can drive the linkage plate to move. When the linkage plate moves, it will drive the abutment rod to slide along the abutment groove opened on the upper side of the striking rod. At this time, under the abutment action of the abutment rod, the striking rod can rotate synchronously along the fixed shaft, thereby striking the feeding box and causing the feeding box to vibrate. The force of the vibration can help the rubber to be put into the shell.

[0018] 3. When the linkage plate moves, it can synchronously drive the slider to slide along the inside of the slide groove. The slide groove can limit the slider, thereby further improving the stability of the linkage plate movement and improving the striking effect of the striking rod.

[0019] 4. When the slider moves along with the linkage plate, it can synchronously drive the stirring rod to move. At this time, the stirring rod can stir the rubber inside the feeding box, thereby preventing the rubber from hardening and further facilitating the rubber feeding operation.

[0029] Rubber can be fed into the housing 1 through the feeding box 4. At this time, the first motor 2 is started. The first motor 2 will drive the spiral extrusion rod 3 on one side to rotate. The spiral extrusion rod 3 can drive the gear 5 to rotate synchronously. At this time, the two sets of spiral extrusion rods 3 can be driven to rotate synchronously under the meshing action of the gear 5, thereby performing the rubber extrusion operation.

[0030] Example 2: Figure 4 , Figure 5 and Figure 6 The present invention provides the following technical solution: an extrusion molding machine for producing rubber parts with rapid feeding capability, disclosing an auxiliary mechanism that accelerates the feeding speed of rubber from the feeding box 4 into the housing 1: the feeding box 4 is provided through the upper surface of the housing 1, and a fixing plate 6 is fixedly connected to the upper side of the feeding box 4; the fixing plate 6 is provided with an auxiliary mechanism to assist in rapid rubber feeding, the auxiliary mechanism including a second motor 7, a lead screw 12 fixedly connected to the output end of the second motor 7, and the other end of the lead screw 12 nested and connected to the fixing plate. 6. A fixed shaft 10 is fixedly connected to the side of the fixed plate 6. A linkage plate 13 is threadedly connected to the outer side of the lead screw 12. An abutment rod 15 is fixedly connected to the outer end of the linkage plate 13. A striking rod 11 is nested on the outer side of the fixed shaft 10.

[0031] After the rubber is fed into the feeding box 4, the second motor 7 can be started, and the auxiliary mechanism can be driven to run. The auxiliary mechanism can accelerate the speed at which the rubber is fed into the housing 1 from the feeding box 4, thereby further improving the rubber extrusion effect. After the second motor 7 is started, it can simultaneously drive the lead screw 12 to rotate. At this time, the lead screw 12 can drive the linkage plate 13 to move.
