Technical Field

[0001] The present application relates to the technical field of material cutting, and in particular to a strip cutting and dicing device. Background Art

[0002] One method for preparing a resin, such as a hydrophilic resin, is to first prepare a continuous resin block and then cut the resin block into resin blocks of a predetermined size.

[0003] Conventional strip cutting devices usually cut discontinuous materials, that is, materials with a preset length, into strips and blocks. Directly cutting continuous rubber blocks into strips and blocks will lead to cutting quality problems such as rubber block accumulation and uneven cutting. Utility Model Content

[0004] The purpose of this application is to solve the problem of low quality of continuous rubber block cutting in the prior art. Therefore, this application provides a striping and slicing device that improves the continuous slicing quality by coordinating different conveyor lines and cutting components in the striping and slicing steps, and by flattening the rubber strips through the limiting area before slicing.

A limiting area for clamping and conveying a continuous rubber block is formed between the first pressing member and the first conveyor line. The cutting assembly is disposed corresponding to an outlet of the limiting area and includes a plurality of first cutters sequentially arranged along the width direction of the first conveyor line. The blades of the plurality of first cutters are all parallel to the length direction of the continuous rubber block to cut it into strips.

The second cutter can move intermittently in the vertical direction, and the blade of the second cutter is parallel to the width direction of the continuous rubber block to cut it into pieces.

[0008] By adopting the above technical solution, the continuous rubber block can be continuously divided into strips by the cooperation of the first conveyor line and the cutting component; the continuous rubber block after stripping can be continuously cut into blocks by the cooperation of the second conveyor line and the second cutter; and, by setting a limiting area in front of the cutting component, pressure can be applied to the rubber block before cutting within a certain distance, so that it is flat up and down, thereby improving the cutting quality; at the same time, the cutting component is set at the outlet of the corresponding limiting area, which can improve the state stability of the rubber block when it contacts the cutting component, that is, it keeps the rubber block in a flat state when being cut, further improving the cutting quality.

[0009] In some embodiments, the cutting unit further includes a second pressing member, which is disposed above the end of the second conveying line and cooperates with the end of the second conveying line to clamp the continuous rubber block.

[0010] By adopting the above technical solution, the flatness of the rubber block before cutting is improved through the cooperation of the second conveying line and the second pressing member, thereby further improving the cutting quality.

[0011] In some embodiments, the second cutter is tilted relative to the plane where the conveying surface of the second conveying line is located, and the tilt angle is an acute angle.

[0012] In some embodiments, the second cutter is connected to a transmission rod, the end of the transmission rod facing away from the second cutter abuts against an eccentric wheel, the eccentric wheel is connected to a motor, and the rotation of the eccentric wheel drives the second cutter to move intermittently in the vertical direction through the transmission rod.

[0013] In some embodiments, the first pressing member is a third conveying line, the third conveying line is arranged in parallel with the first conveying line, and the end of the third conveying line is arranged close to the end of the first conveying line.

[0014] The above technical solution can achieve the leveling of the continuous rubber block while ensuring that the rubber block is stably transmitted when subjected to the resistance of the cutting assembly and the first pressure member, thereby improving the reliability of rubber block transmission and further improving the reliability of cutting.

[0015] In some embodiments, a pressure rod is connected to one end of the first pressing member close to the cutting assembly, and the pressure rod applies pressure to the corresponding end of the first pressing member toward the first conveying line.

[0016] In some embodiments, the first cutter is a circular roller cutter, and the plurality of first cutters are connected to the same rotating shaft, and the rotating shaft is connected to a roller cutter motor.

[0017] In some embodiments, the second pressing member is a fourth conveying line inclined toward the end of the second conveying line;

[0018] The fourth conveying line and the second conveying line jointly clamp and convey the continuous rubber block toward the second cutter.

[0019] By adopting the above technical solution, the rubber blocks can be leveled while ensuring the stability and reliability of rubber block transmission, preventing some rubber blocks from being retained on the second conveyor line and affecting subsequent rubber block cutting, thereby improving cutting reliability.

[0020] In some embodiments, the first conveying line and the second conveying line are both conveying chain plates.

[0032] See Figure 1 , Figure 1 This is a structural diagram of an embodiment of the present application.

[0033] The present invention provides a striping and dicing device, particularly suitable for striping and dicing continuous rubber blocks. A continuous rubber block is a rubber block of a certain length that, in particular, is continuously produced along its length through a previous process. The slicing of such rubber blocks must be coordinated with the production process, meaning that continuous and uninterrupted slicing must be performed simultaneously with continuous and uninterrupted production.

[0034] The device includes a slitting unit 100 and a cutting unit 200 arranged corresponding to the discharge port of the slitting unit 100.

[0035] The slitting unit 100 includes a first conveying line 110 , a first pressing member 120 disposed above the first conveying line 110 , and a cutting assembly.

[0036] A limiting area for clamping and conveying continuous rubber blocks is formed between the first pressing member 120 and the first conveying line 110, so as to continuously apply pressure to the rubber blocks before cutting within a certain distance, making them flat from top to bottom, thereby improving the cutting quality.

[0037] The cutting assembly includes multiple first cutters 130 arranged along the width of the first conveyor line 110. The blades of these first cutters 130 are parallel to the length of the continuous rubber block to separate it into strips. Furthermore, the coordination between the first conveyor line 110 and the cutting assembly allows for continuous stripping in accordance with the production speed of the rubber block.

[0038] Preferably, the cutting assembly is arranged corresponding to the outlet of the limiting area, thereby improving the stability of the state of the rubber block when it contacts the cutting assembly, that is, keeping it in a flat state when being cut, further improving the cutting quality.

[0039] The slicing unit 200 includes an intermittent second conveyor line 210, terminated by a second cutter 230, enabling a single-feed, single-cut process. The second cutter 230 intermittently moves vertically, with its blade aligned parallel to the width of the continuous rubber block to facilitate slicing. The coordination of the second conveyor line 210 and the second cutter 230 also allows for continuous slicing at the same speed as the stripping process.

[0040] In a specific embodiment, the second conveying line 210 and the second cutter 230 are both driven by a stepping motor.

[0041] In one embodiment, the cutting unit 200 further includes a second pressing member 220, which is disposed above the end of the second conveyor line 210 and cooperates with the end of the second conveyor line 210 to clamp the continuous rubber block, thereby improving the flatness of the rubber block before cutting, thereby further improving the cutting quality.

[0042] In one embodiment, the second cutter 230 is tilted relative to the plane of the conveying surface of the second conveyor line 210, and the tilt angle is an acute angle. Preferably, the tilt angle is 5-10 degrees offset from the vertical angle, thereby forming a rubber block with a certain slope, so that the rubber block pours toward the outlet surface.

[0043] In one embodiment, the second cutter 230 is connected to a transmission rod 231 , and the end of the transmission rod 231 facing away from the second cutter 230 abuts against the eccentric wheel 232 to enable the second cutter 230 to move up and down for cutting.

[0044] In a specific embodiment, the eccentric wheel 232 is connected to a motor, and the eccentric wheel 232 rotates through the transmission rod 231 to drive the second cutter 230 to move intermittently in the vertical direction.

[0045] In one embodiment, the first pressure member 120 is a third conveyor line, which is arranged parallel to the first conveyor line 110, and the end of the third conveyor line is arranged close to the end of the first conveyor line 110. While achieving the leveling of continuous rubber blocks, it ensures that the rubber blocks maintain stable transmission when subjected to resistance from the cutting assembly and the first pressure member 120, thereby improving the reliability of rubber block transmission and thereby improving the cutting reliability.

[0046] In one embodiment, a pressure rod 121 is connected to one end of the first pressing member 120 near the cutting assembly. The pressure rod 121 applies pressure to the corresponding end of the first pressing member 120 toward the first conveyor line 110, further improving the reliability and accuracy of the strip cutting. The pressure rod 121 can be a pneumatic rod.

[0047] In one embodiment, the first cutter 130 is a circular roller cutter, and multiple first cutters 130 are connected to the same shaft, which is connected to a roller cutter motor 131. That is, the first cutter 130 rotates while performing strip cutting, thereby improving the reliability of strip cutting.

[0048] In one embodiment, the second pressing member 220 is a fourth conveying line inclined toward the end of the second conveying line 210 .

[0049] The fourth conveyor line and the second conveyor line 210 jointly clamp and convey continuous rubber blocks toward the second cutter 230, ensuring the stability and reliability of rubber block transmission while leveling the rubber blocks, preventing some rubber blocks from remaining on the second conveyor line 210 and affecting subsequent rubber block cutting, thereby improving cutting reliability.

[0050] In one embodiment, the first conveyor line 110 and the second conveyor line 210 are both conveyor chain plates, ie, rigid conveyor lines, thereby preventing them from being damaged by the first cutter 130 or the second cutter 230 and extending their service life.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application.
