Description

Technical Field

[0001] This utility model belongs to the field of rubber compounding, specifically relating to a rubber compound sheet separation and powdering mechanism and sheet-swinging device. Background Technology

[0002] Rubber undergoes plasticizing and mixing with modified additives, fillers, and other functional auxiliaries. After calendering, cooling, and other processes, semi-finished products are stacked and collected, or finished products are packed into boxes. Because uncured rubber is not yet cross-linked, the rubber sheets are prone to sticking together during stacking or packing due to the influence of heavy pressure and ambient temperature.

[0003] Currently, the traditional method for addressing the issue of rubber compounds easily sticking together is to pass the rubber sheet through a separator powder hopper and then use a brush to sweep off the excess powder. However, due to the brush, the amount of separator powder covering the rubber sheet is very small. In cases where the rubber compound has strong self-adhesion or is relatively soft, the tiny amount of separator powder remaining after brushing easily fuses with the uncrosslinked rubber, losing its separator function and causing the rubber sheets to stick together. Without brushing, the rubber sheets will experience uneven adhesion of the separator powder as they pass through the separator powder hopper, affecting subsequent use.

[0004] Therefore, finding a more effective method for applying the separating powder is crucial for preventing the rubber sheets from sticking together, facilitating subsequent operations, and ensuring product performance. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a compound rubber sheet separation powder spreading mechanism and sheet swaying device that provides a uniform and sufficient amount of separation powder and requires no additional power.

[0006] This utility model provides a compound rubber sheet isolation powdering mechanism, including a powdering box, which is used to hold isolation powder, and a powder outlet filter screen is provided at the bottom of the powdering box;

[0007] The powder dispensing box is installed on the swing head of the swivel machine, and the powder discharge filter discharges powder through the swing of the swivel head of the swivel machine.

[0008] Furthermore, the filter pore size of the powder outlet filter is changed according to the viscosity characteristics of the produced compound rubber sheet.

[0009] Furthermore, the powder dispensing box is equipped with a powder storage box, and the powder storage box has a powder outlet on the side facing the powder outlet filter.

[0010] Furthermore, the size of the powder outlet projected onto the powder outlet filter is smaller than that of the powder outlet filter.

[0011] Furthermore, there are two powder outlets, which are arranged symmetrically about the central axis of the powder filter.

[0012] Furthermore, the powder-spreading box has a trapezoidal platform structure, and the powder-discharging filter screen is arranged at the small end of the trapezoidal platform.

[0013] This utility model also provides a sheet-splitting device, including a conveying mechanism, a sheet-splitting machine head, a finished product box, and the above-mentioned compound rubber sheet isolation and powdering mechanism;

[0014] The powder-spreading box is installed on the swing head of the slab mill, and the powder-discharging filter screen faces the internal outlet of the swing head of the slab mill.

[0015] Furthermore, the powder-sprinkling box is located at the end of the sway head of the swaying machine that is away from the conveying mechanism.

[0016] Furthermore, the central axis of the swivel head of the swivel machine is inclined to the central axis of the powder-spreading box.

[0017] Furthermore, the powder-spreading box is fixedly mounted on the sway head of the swaying machine by fasteners.

[0018] The beneficial effects of this invention are as follows: the powder-spreading box is installed on the oscillating head of the film-shaping machine. The left-right oscillation of the oscillating head serves as the power for the falling isolation powder. Furthermore, because the powder-spreading box oscillates together with the oscillating head, the falling isolation powder consistently lands on the film surface in the finished product box directly below. This ensures that the isolation powder is sufficiently and evenly distributed on the film stacking surface, preventing the powder from adhering only to a fixed amount on the film surface due to brush cleaning, thus achieving a good isolation effect. The powder outlet filter not only ensures the uniformity of the falling isolation powder but also prevents the powder from continuing to fall when the oscillating head stops operating, acting as a falling switch in conjunction with the oscillating head's running status.

[0019] Compared to the existing method where the film passes through the separating powder box and then the excess film is swept off with a brush, this invention ensures that the separating powder covering the film is uniform and sufficient, thus guaranteeing the separating effect. At the same time, it does not require additional driving power and will not increase energy consumption. Attached Figure Description

[0030] As attached Figure 1 -Appendix Figure 4 As shown, this utility model provides a compound rubber sheet isolation powdering mechanism, including a powdering box 1, which is used to hold isolation powder, and a powder outlet filter 3 is provided at the bottom of the powdering box 1;

[0031] The powder dispensing box 1 is installed on the swing head 6 of the slab machine, and the powder discharge filter 3 discharges powder through the swing of the swing head 6 of the slab machine.

[0032] During operation, the powder-spreading box 1 sways left and right along with the swing head 6 of the sheet-splitting machine. During this swaying, the powder residue on the powder outlet filter 3 is forced through the filter holes and falls evenly. This falling process follows the swing head 6 along with the mixed rubber sheet 9 into the finished product box 8 below, achieving continuous and even powdering of the mixed rubber sheet 9 and preventing it from sticking together. When the equipment stops running, the swing head 6 is stationary, and the powder-spreading box 1 also remains stationary. At this time, the powder residue in the powder-spreading box 1 accumulates on the powder outlet filter 3 and stops falling, thus stopping the powder residue's descent.

[0033] The powder-spreading box 1 of this invention is installed on the swing head 6 of the wafer slab machine. The left-right swing of the swing head 6 provides the power for the falling isolation powder. Since the powder-spreading box 1 swings together with the swing head 6, the falling isolation powder always lands on the surface of the rubber compound sheet 9 in the finished product box 8 directly below. This ensures that the isolation powder on the stacked surface of the rubber compound sheet 9 is sufficiently uniform, preventing the powder from adhering only to a fixed amount on the surface of the rubber compound sheet 9 due to brushing, thus achieving a good isolation effect. The powder discharge filter 3 ensures the uniformity of the falling isolation powder and prevents further falling of the isolation powder when the swing head 6 stops operating, acting as a falling switch in conjunction with the operating status of the swing head 6.

[0034] Compared to the existing method where the rubber sheet 9 passes through the isolation powder box and then the excess powder on the sheet is swept off with a brush, this invention ensures that the isolation powder covering the rubber sheet 9 is uniform and sufficient, thus guaranteeing the isolation effect. At the same time, it does not require additional driving power and will not increase energy consumption.

[0035] In one embodiment, the filter mesh size of the powder outlet filter 3 is changed according to the viscosity characteristics of the produced rubber compound sheet 9. Preferably, the powder outlet filter 3 can be selected with a mesh size between 5 and 60 mesh. In use, a suitable size powder outlet filter 3 and isolation powder can be selected for rubber compounds with different viscosities and hardnesses, which can control the amount of isolation powder falling and ensure the uniformity of powder application. It has good adaptability to anti-sticking isolation of rubber compound sheets 9 with different viscosities and hardnesses.

[0036] In one embodiment, the powder dispensing box 1 is provided with a powder storage box 2, and the powder storage box 2 has a powder outlet 4 on the side facing the powder outlet filter 3. In this embodiment, the powder storage box 2 is used to store the isolation powder, so as to prevent all the isolation powder in the powder dispensing box 1 from accumulating on the powder outlet filter 3 at one time. When the oscillating machine is started and the oscillating head 6 of the oscillating machine begins to swing left and right, the powder dispensing box 1 and the powder storage box 2 will swing together with the oscillating head 6 of the oscillating machine. At this time, the isolation powder stored in the powder storage box 2 will fall down onto the powder outlet filter 3 through the powder outlet 4 under its own gravity. The isolation powder falling onto the powder outlet filter 3 will pass through the pores of the powder outlet filter 3 and begin to fall evenly downwards due to the swing of the oscillating head 6 of the oscillating machine.

[0037] In one embodiment, the size of the powder outlet 4 projected onto the powder outlet filter 3 is smaller than that of the powder outlet filter 3. This prevents the isolation powder coming out of the powder outlet 4 of the powder storage box 2 from completely covering the powder outlet filter 3. On the one hand, this avoids clogging of the powder outlet filter 3, and on the other hand, it ensures that the isolation powder falls evenly during the oscillation of the powder outlet filter 3.

[0038] In one embodiment, there are two powder outlets 4, which are arranged symmetrically about the central axis of the powder filter screen 3. This arrangement can ensure the uniformity of the powder storage box 2 falling onto the powder filter screen 3.

[0039] In one embodiment, the powder-spreading box 1 has a trapezoidal platform structure, and the powder-discharging filter 3 is arranged at the small end of the trapezoidal platform. This arrangement can reduce the intrusion into the inside of the swivel head 6 of the swivel machine while ensuring the internal volume of the powder-spreading box 1, thus ensuring the normal use of the swivel head 6 of the swivel machine.

[0040] This utility model also provides a stacking device for stacking rubber sheets 9 in a finished product box 8. The stacking device includes a conveying mechanism 7, a stacking head 6, a finished product box 8, and the aforementioned rubber sheet separation and powdering mechanism. The conveying mechanism 7 is used to convey the rubber sheets 9. The stacking head 6 is located downstream of the conveying mechanism 7, and one end of the inlet of the conveying mechanism 7 is hinged to the downstream of the conveying mechanism 7. The other end is used to fix the powdering box 1. The outlet of the stacking head 6 is located above the inlet of the finished product box 8.

[0041] The powder-spreading box 1 is mounted on the swing head 6 of the slab mill, and the powder outlet filter 3 faces the internal outlet of the swing head 6. During operation, the powder-spreading box 1 swings left and right along with the swing head 6. During this swing, the powder residue on the powder outlet filter 3 is forced through the filter holes and falls evenly. This falling process follows the swing head 6 along with the rubber sheet 9 into the finished product box 8 below, achieving continuous and even powdering of the rubber sheet 9 and preventing adhesion of the rubber sheet 9 in the finished product box 8. When the equipment stops running, the swing head 6 is stationary, and the powder-spreading box 1 also remains stationary. At this time, the powder residue in the powder-spreading box 1 accumulates on the powder outlet filter 3 and stops falling, thus stopping the powder residue's descent.

[0042] In one embodiment, the powder-spreading box 1 is located at the end of the inlet of the sway head 6 of the swaying machine that is away from the conveying mechanism 7. This arrangement can prevent the powder-spreading box 1 from encroaching too much into the inlet space of the sway head 6 of the swaying machine, and at the same time facilitates the replacement of the powder discharge filter 3 at the bottom of the powder-spreading box 1.

[0043] In one embodiment, the central axis of the swaying head 6 of the slab mill is inclined to the central axis of the powder dispensing box 1, that is, the direction of the powder outlet filter 3 of the powder dispensing box 1 is towards the side wall of the swaying head 6 near the conveying mechanism 7. At this time, no matter what position the swaying head 6 and the powder dispensing box 1 are in, the isolation powder falling from the powder outlet filter 3 at the bottom of the powder dispensing box 1 will fall from the outlet of the swaying head 6 into the surface of the compound rubber sheet 9 in the finished product box 8 directly below by inertia, thereby ensuring the coating effect of the isolation powder.

[0044] In one embodiment, the powder-spreading box 1 is fixedly mounted on the tilting head 6 of the tilting machine by fasteners 5. This arrangement facilitates the installation of the powder-spreading box 1 on the tilting head 6 of an existing tilting machine, and the fasteners 5 are preferably bolt fasteners.

[0045] The above description is merely an embodiment and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations, modifications, or alterations to the technical solution of this utility model without departing from its scope. Therefore, any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model, without departing from its scope, should fall within the protection scope of this utility model.
