Description

Technical Field

[0001] This utility model relates to the field of rubber material production technology, and in particular to a cutting device for anti-overflow styrene-butadiene rubber sheets. Background Technology

[0002] Styrene-butadiene rubber, also known as polystyrene-butadiene copolymer, has physical and structural properties, processing properties, and product performance similar to natural rubber. In some aspects, such as abrasion resistance, heat resistance, aging resistance, and vulcanization speed, it is even superior to natural rubber.

[0003] After styrene-butadiene rubber (SBR) is processed into sheets, a cutting device is used to cut the sheets into specific shapes to meet the needs of different products. Existing patent document CN218082915U provides a rapid cutting device for plastic sheets. This device utilizes a rotating shaft and a rotating motor to control the sliding plate to slide up and down, using blades on a module for cutting. During use, the rotating motor drives the rotating shaft, which, in conjunction with a connecting shaft and a rotating block, causes the connecting rod to move up and down, moving the sliding plate. A module under the sliding plate performs precise measurements, and then the blades are used for cutting, preventing the production of items with inconsistent quality. The use of a rotating motor saves significant manpower, resources, and time.

[0004] Due to the deformable nature of plastic sheets, the cut plastic sheets tend to become clogged inside the blades after cutting, making it difficult to cut the next batch of sheets and requiring manual cleaning, thus reducing its practicality. Therefore, there is an urgent need for an anti-overflow styrene-butadiene rubber sheet cutting device to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned problems that the existing device easily clogs the blades after cutting plastic sheets due to the deformation characteristics of the plastic sheets, making it difficult to continue cutting the next batch of plastic sheets and requiring manual cleaning, thus reducing its practicality, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide an anti-overflow styrene-butadiene rubber sheet cutting device, which aims to solve the problem that due to the deformation characteristics of plastic sheets, the plastic sheets after cutting are easily clogged in the blades, making it difficult to continue cutting the next batch of plastic sheets, requiring manual cleaning, and thus having low practicality.

[0007] To solve the above technical problems, this utility model provides the following technical solution: a styrene-butadiene rubber sheet cutting device with anti-overflow adhesive, including a base plate, a connecting frame fixedly connected to the base plate, a lifting component installed on the connecting frame, a plurality of cutting molds connected to the lifting component, a pushing mechanism installed on the cutting molds, and a crossbar connected to the connecting frame, the crossbar abutting and cooperating with the pushing mechanism;

[0008] The material pushing mechanism includes a connecting seat fixedly connected to the cutting mold, and a driving rod elastically connected inside the connecting seat. One end of the driving rod passes through the cutting mold and is fixedly connected to a push plate.

[0009] In a preferred embodiment of the anti-overflow styrene-butadiene rubber sheet cutting device of this utility model, the lifting component includes a connecting plate, both ends of which are fixedly connected to electric push rods. The electric push rods are fixedly installed on the connecting frame, and the connecting plate is connected to the cutting mold through a connecting rod.

[0010] In a preferred embodiment of the anti-overflow styrene-butadiene rubber sheet cutting device of this utility model, the driving rod is slidably connected to the connecting seat, a spring is elastically connected between the driving rod and the connecting seat, and the driving rod abuts against the crossbar.

[0011] As a preferred embodiment of the anti-overflow styrene-butadiene rubber sheet cutting device of this utility model, the connecting frame has two guide plates hinged in the middle, the guide plates are hinged to the crossbar and a pull rod is connected, and the crossbar is vertically slidably connected to the connecting frame.

[0012] As a preferred embodiment of the anti-overflow styrene-butadiene rubber sheet cutting device of this utility model, wherein: a pressure plate is elastically connected to the connecting frame by a second spring, and a driving plate is elastically connected to one side of the cutting mold by a third spring, and the driving plate abuts against the pressure plate.

[0013] As a preferred embodiment of the anti-overflow styrene-butadiene rubber sheet cutting device of this utility model, the driving plate is vertically slidably connected to the cutting mold, and the sum of the three spring forces is greater than the sum of the two spring forces.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model uses a lifting frame to drive the cutting mold to rise and fall, thereby cutting rubber sheets. The cut rubber sheets are blocked inside the cutting mold. When the cutting mold rises to the point where the driving rod and the crossbar abut, the push plate can push the sheet out of the cutting mold. At the same time, the crossbar drives the guide plate to rotate and tilt, so that the sheet slides to both sides on the guide plate and is automatically collected.

[0016] 2. This utility model uses a cutting mold to bring the driving plate into contact with the pressure plate during the descent process, so that the pressure plate presses and limits the rubber sheet to be cut, thereby preventing deviation during the cutting process and improving the cutting accuracy.

Detailed Implementation

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Example 1

[0027] Reference Figure 1-4 This is the first embodiment of the present invention, which provides an anti-overflow styrene-butadiene rubber sheet cutting device. The anti-overflow styrene-butadiene rubber sheet cutting device includes a base plate 1, a connecting frame 101 fixedly connected to the base plate 1, a lifting component 2 installed on the connecting frame 101, a plurality of cutting molds 3 connected to the lifting component 2, a pushing mechanism 4 installed on the cutting molds 3, and a crossbar 5 connected to the connecting frame 101. The crossbar 5 abuts and cooperates with the pushing mechanism 4.

[0028] The material pushing mechanism 4 includes a connecting seat 401 fixedly connected to the cutting mold 3. A driving rod 402 is elastically connected inside the connecting seat 401. One end of the driving rod 402 passes into the cutting mold 3 and is fixedly connected to a push plate 404.

[0029] In the above technical solution, the base plate 1 is used to place the styrene-butadiene rubber sheet to be cut, and the lifting component 2 is used to drive each cutting mold 3 to move up and down synchronously. When the cutting mold 3 descends, it contacts the styrene-butadiene rubber sheet and completes the cutting. The cut sheet is blocked in the cutting mold 3. Then, when the lifting component 2 rises, it causes the driving rod 402 to abut against the crossbar 5. At this time, the cutting mold 3 continues to rise while the push plate 404 remains stationary, so that the push plate 404 can push out the sheet in the cutting mold 3.

[0030] It is understandable that multiple cutting molds 3 are arranged in an array, and each cutting mold 3 consists of a hollow shell and a cut at its lower end. The shape of the cutting mold 3 is selected to match the shape of the sheet to be cut.

[0031] The lifting component 2 includes a connecting plate 201, with electric push rods 202 fixedly connected to both ends of the connecting plate 201. The electric push rods 202 are fixedly installed on the connecting frame 101, and the connecting plate 201 is connected to the cutting mold 3 through the connecting rod 203. The two electric push rods 202 extend and retract synchronously, so that the connecting plate 201 drives the cutting mold 3 to move up and down through the connecting rod 203.

[0032] The driving rod 402 is slidably connected to the connecting seat 401, and a spring 403 is elastically connected between the driving rod 402 and the connecting seat 401. The driving rod 402 is also in contact with the crossbar 5.

[0033] In the above technical solution, spring 403 is sleeved on drive rod 402. When spring 403 is compressed, it drives push plate 404 to be located on the upper side inside cutting mold 3. Drive rod 402 has an L-shaped structure, with its upper horizontal end passing through connecting seat 401. When drive rod 402 rises to abut against crossbar 5 and cutting mold 3 continues to rise, push plate 404 remains stationary, thereby pushing the blocked sheet material inside cutting mold 3 downward.

[0034] Two guide plates 6 are hinged in the middle of the connecting frame 101. A pull rod 601 is hinged between the guide plate 6 and the crossbar 5, and the crossbar 5 is vertically slidably connected to the connecting frame 101.

[0035] In the above technical solution, when the driving rod 402 contacts the crossbar 5, it first drives the crossbar 5 to rise. The crossbar 5 drives the guide plate 6 to rotate through the pull rod 601. The two guide plates 6 unfold in a V-shape. Then, when the crossbar 5 can no longer slide, the driving rod 402 abuts against the crossbar 5 to make the push plate 404 stop, pushing the sheet material blocked in the cutting mold 3 downward. Under the guidance of the guide plate 6, the sheet material slides to both sides of the base plate 1, forming automatic separation and avoiding repeated cutting.

[0036] During use, the styrene-butadiene rubber sheet to be cut is placed on the base plate 1. The electric push rod 202 drives the connecting plate 201 to descend, and through the connecting rod 203, it drives the cutting mold 3 to descend. The cutting mold 3 cuts the styrene-butadiene rubber sheet. The required sheet is blocked inside the cutting mold 3. Then, the electric push rod 202 drives the connecting plate 201 to rise. When the driving rod 402 contacts the crossbar 5, it first drives the crossbar 5 to rise. The crossbar 5 drives the guide plate 6 to rotate through the pull rod 601. The two guide plates 6 unfold in a V-shape. Then, when the crossbar 5 can no longer slide, the driving rod 402 abuts against the crossbar 5, causing the push plate 404 to stop. At this time, the cutting mold 3 continues to rise while the push plate 404 stops, so that the push plate 404 can push out the sheet in the cutting mold 3. Under the guidance of the guide plate 6, the sheet slides to both sides of the base plate 1, forming an automatic separation.

[0037] Example 2

[0038] Reference Figure 5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a pressure plate 7 is elastically connected to the connecting frame 101 by a second spring 701, and a driving plate 8 is elastically connected to one side of the cutting mold 3 by a third spring 801. The driving plate 8 abuts against the pressure plate 7.

[0039] In the above technical solution, when the cutting mold 3 descends, it first contacts the pressure plate 7 by driving the plate 8, which in turn drives the pressure plate 7 to descend. This causes the pressure plate 7 to press and limit the styrene-butadiene rubber sheet to be cut, preventing the sheet from shifting during the subsequent cutting process of the cutting mold 3, thus improving the cutting accuracy.

[0040] The driving plate 8 is vertically slidably connected to the cutting mold 3, and the total elastic force of spring 3 801 is greater than the total elastic force of spring 2 701. When the driving plate 8 descends and contacts the pressure plate 7, spring 2 701 is stretched by force, causing the pressure plate 7 to descend. When the pressure plate 7 comes into contact with the sheet and cannot continue to descend, the driving plate 8 remains stationary. At this time, when the cutting mold 3 descends, spring 3 801 is stretched.

[0041] The remaining structure is the same as that in Example 1.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
