Description

Technical Field

[0001] The invention relates to a rubber mixing device, in particular to a rubber mixing device. Background Art

[0002] At present, open mill is the abbreviation of open plastic refining machine. In plastic product factories, people are accustomed to calling it a two-roller machine. Open mill is a kind of plastic mixing equipment that was used earlier by silicone and other product manufacturers. Its function is to mix and plasticize the uniformly mixed raw materials and provide a relatively uniform melt for the calender to form plastic film. The existing silicone open mill mainly includes a frame, a driving mechanism fixed on the frame and two rubber refining rollers arranged oppositely. The two rubber refining rollers are rotatably connected to the frame. When refining, the block silicone is placed between the two rubber refining rollers.

[0003] However, the existing open refining device has the following defects:

[0004] (1) The existing open refining device only utilizes the rotation of two rubber mixing rollers to make the two rubber mixing rollers repeatedly squeeze the rubber. This method requires multiple repeated operations, which is time-consuming and labor-intensive, and greatly reduces the production efficiency of rubber.

[0005] (2) When the existing open refining device is refining rubber, if defective rubber appears, it is necessary to manually pick up the rubber, climb to the top of the device, and throw the rubber into the feed port of the open refining device, which is labor-intensive. Summary of the invention

[0006] In order to solve one or some technical problems existing in the prior art, one of the purposes of the present application is to provide a rubber refining device, which can play the role of tanning and refining rubber, and can fully tan the rubber to achieve the refining effect.

[0007] In order to solve the above existing technical problems, one of the purposes of this application is achieved by adopting the following technical solution:

[0008] A rubber refining device comprises two vertical plates symmetrically arranged front and back, a box body fixedly arranged at the right ends of the two vertical plates, a hopper connected to the top of the box body, a conical pressing component arranged in the box body, and an extrusion component arranged between the two vertical plates. The conical pressing component plays a role in tanning and conveying the rubber, and the extrusion component plays a role in extrusion molding the rubber. The rubber put into the box body through the hopper can be conveyed to the extrusion component under the action of the conical pressing component, thereby effectively refining the rubber.

[0009] Further, the conical compacting assembly includes an opening formed in the left side wall of the box body, a driving shaft and a driven shaft arranged front and back and penetrating between the opening and the right side wall of the box body, two spiral blades located on the driving shaft and the driven shaft and arranged crosswise, a driving gear fixedly sleeved on the driving shaft, a driven gear fixedly sleeved on the driven shaft and meshing with the driving gear, a compacting motor fixedly arranged on the right side wall of the box body, the output end of the compacting motor being fixedly connected to the driving shaft and rotating coaxially, the left ends of the driving shaft and the driven shaft being arranged close to each other, the right end of the driving shaft and the right end of the driven shaft being arranged away from each other, and the spiral blades being integrally conical.

[0010] Further, the extrusion assembly includes an L-shaped mounting rod fixedly arranged on the rear vertical plate, an extrusion motor fixedly arranged on the L-shaped mounting rod, a driving rod rotatably connected between the two vertical plates and being rotated forward and backward by the extrusion motor, a driven rod rotatably connected between the two vertical plates, extrusion rollers fixedly sleeved on the driving rod and the driven rod, a first gear fixedly sleeved on the driving rod, and a second gear fixedly sleeved on the driven rod and meshing with the first gear.

[0011] Further, a guide plate is also fixedly arranged between the two vertical plates. The guide plate is located below the two extrusion rollers, is fixedly connected to the box body, and is located below the opening.

[0012] Further, a lifting assembly is also inclined between the two vertical plates. The lifting assembly can lift defective rubber into the hopper. The lifting assembly is located above the extrusion assembly. The lifting assembly includes a mounting plate fixedly arranged between the two vertical plates, a lifting motor fixedly arranged on the front mounting plate, a first rotating shaft rotatably connected between the two mounting plates and being rotated forward and backward by the lifting motor, a driving roller fixedly sleeved on the first rotating shaft, a second rotating shaft rotatably connected between the two mounting plates, a driven roller fixedly sleeved on the second rotating shaft, and a transmission belt drivingly connected between the driving roller and the driven roller.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] (1) By providing the conical compacting assembly, it plays a role in tanning and kneading the rubber, can fully tan the rubber, achieve the kneading effect, avoid repeated operations, save time and effort. Compared with the existing kneading devices, it solves the technical problem that the existing kneading devices only use the rotation of two rubber kneading rollers to repeatedly extrude the rubber. In this way, multiple repeated operations are required, which is time-consuming and laborious, and greatly reduces the production efficiency of the rubber.

[0015] (2) By setting up a lifting component and utilizing the conveyance of the conveyor belt, it is convenient to put the defective rubber products into the hopper, avoiding the need for workers to climb to the top of the device again, which helps to reduce the manual labor. Compared with the existing kneading device, when kneading rubber, in the case of defective rubber products, the existing kneading device still requires workers to pick up the rubber and climb to the top of the device to put the rubber into the feeding port of the kneading device, which consumes a lot of manual labor. This solves the technical problem. Brief Description of the Drawings

It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same category, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the specification and claims means at least one of the connected objects. The character " / ", generally represents an "or" relationship between the associated objects, which is a rubber kneading device. Embodiment 1:

[0028] As Figures 1-8 shown, this embodiment provides a rubber kneading device, which includes two vertical plates 8 symmetrically arranged front and back, a box body 10 fixedly arranged at the right end of the two vertical plates 8, and further includes a hopper 3 communicated with the top of the box body 10, a conical pressing and compacting assembly 4 arranged in the box body 10, and an extrusion assembly 7 arranged between the two vertical plates 8. The conical pressing and compacting assembly 4 plays a role in tanning and conveying the rubber, and the extrusion assembly 7 plays a role in extruding and forming the rubber. The rubber put into the box body 10 through the hopper 3 can be conveyed to the extrusion assembly 7 under the action of the conical pressing and compacting assembly 4, so as to effectively knead the rubber.

[0029] When using this device, put the rubber into the hopper 3, and then start the conical pressing and compacting assembly 4 and the extrusion assembly 7. The conical pressing and compacting assembly 4 tans the rubber roller and at the same time conveys the rubber, so that the rubber is conveyed into the extrusion assembly 7, and the extrusion assembly 7 extrudes the rubber to form it into a sheet.

[0030] By setting the conical pressing and compacting assembly 4, it plays a role in tanning and kneading the rubber, can fully tan the rubber, achieve the kneading effect, avoid repeated operations, save time and effort. Compared with the existing kneading devices, it solves the technical problem that the existing kneading devices only use the rotation of two rubber mixing rollers to repeatedly extrude the rubber, which requires repeated operations, is time-consuming and laborious, and greatly reduces the production efficiency of the rubber.

[0031] The conical compacting assembly 4 includes an opening 28 formed in the left side wall of the box body 10, a driving shaft 12 and a driven shaft 13 that are arranged front and back and penetrate between the opening 28 and the right side wall of the box body 10, two spiral blades 5 that are located on the driving shaft 12 and the driven shaft 13 and are arranged crosswise, a driving gear 6 fixedly sleeved on the driving shaft 12, a driven gear 14 fixedly sleeved on the driven shaft 13 and meshing with the driving gear 6, a compacting motor 11 fixedly arranged on the right side wall of the box body 10, the output end of the compacting motor 11 is fixedly connected to the driving shaft 12 and rotates coaxially, the left ends of the driving shaft 12 and the driven shaft 13 are arranged close to each other, the right end of the driving shaft 12 and the right end of the driven shaft 13 are arranged away from each other, and the spiral blades 5 are integrally conical.

[0032] When using the conical compacting assembly 4, start the compacting motor 11. The compacting motor 11 drives the driving shaft 12 to rotate. The driving shaft 12 drives the driving gear 6 to rotate. The driving gear 6 drives the driven gear 14 to rotate. The driven gear 14 drives the driven shaft 13 to rotate. Both the driving shaft 12 and the driven shaft 13 drive the spiral blades 5 to rotate, so that the two spiral blades 5 knead and press the rubber, realizing the open mixing of the rubber. The rubber is finally conveyed into the extrusion assembly 7 through the opening 28 along with the extrusion and conveyance of the two spiral blades 5. The two spiral blades 5 are arranged staggeredly, further increasing the tanning effect on the rubber.

[0033] The extrusion assembly 7 includes an L-shaped mounting rod 19 fixedly arranged on the rear side vertical plate 8, an extrusion motor 20 fixedly arranged on the L-shaped mounting rod 19, a driving rod 15 rotatably connected between the two vertical plates 8 and reversely rotated by the extrusion motor 20, a driven rod 16 rotatably connected between the two vertical plates 8, extrusion rollers 9 fixedly sleeved on the driving rod 15 and the driven rod 16, a gear one 17 fixedly sleeved on the driving rod 15, and a gear two 18 fixedly sleeved on the driven rod 16 and meshing with the gear one 17.

[0034] When using the extrusion assembly 7, start the extrusion motor 20. The extrusion motor 20 drives the driving rod 15 to rotate. The driving rod 15 drives the gear one 17 to rotate. The gear one 17 drives the gear two 18 to rotate. The gear two 18 drives the driven rod 16 to rotate. Both the driving rod 15 and the driven rod 16 drive the extrusion rollers 9 to rotate. The two extrusion rollers 9 extrude the conveyed rubber. The structure is simple and the use is convenient.

[0035] A guide plate 27 is also fixedly arranged between the two vertical plates 8. The guide plate 27 is located below the two extrusion rollers 9. The guide plate 27 is fixedly connected to the box body 10. The guide plate 27 is located below the opening 28. The arrangement of the guide plate 27 plays a role in supporting the conveyance of the rubber, which helps the rubber to be smoothly conveyed between the two extrusion rollers 9.

[0036] There is also a lifting component 2 inclined between the two vertical plates 8. The lifting component 2 can lift defective rubber into the hopper 3. The lifting component 2 is located above the extrusion component 7. The lifting component 2 includes a mounting plate 21 fixedly arranged between the two vertical plates 8, a lifting motor 22 fixedly arranged on the front mounting plate 21, a first rotating shaft 23 rotatably connected between the two mounting plates 21 and rotating forward and backward by the lifting motor 22, a driving roller 25 fixedly sleeved on the first rotating shaft 23, a second rotating shaft 24 rotatably connected between the two mounting plates 21, a driven roller 26 fixedly sleeved on the second rotating shaft 24, and a transmission belt 1 drivingly connected between the driving roller 25 and the driven roller 26.

[0037] When using the lifting component 2, place the defective rubber on the transmission belt 1, and then start the lifting motor 22. The lifting motor 22 drives the first rotating shaft 23 to rotate. The first rotating shaft 23 drives the driving roller 25 to rotate. The driving roller 25 drives the transmission belt 1 to rotate. The transmission belt 1 drives the driven roller 26 to rotate. As the transmission roller rotates, the defective rubber is put into the hopper 3, realizing the secondary kneading of the defective rubber.

[0038] By setting the lifting component 2 and using the conveying of the transmission belt 1, it is convenient to put the defective rubber into the hopper 3, avoiding the need for workers to climb to the top of the device again, which helps to reduce the labor intensity of workers. Compared with the existing kneading device, it solves the technical problem that when the existing kneading device kneads rubber and there are defective rubber products, workers still need to pick up the rubber, climb to the top of the device, and put the rubber into the feeding port of the kneading device, which is quite labor-consuming.

[0039] The above embodiments are only the preferred embodiments of the present application and cannot be used to limit the scope of protection of the present application. Any non-substantive changes and substitutions made by those skilled in the art based on the present application belong to the scope of protection required by the present application.
