Description

Technical Field

[0001] This utility model relates to the field of foam board production technology, and specifically to a pressure roller mechanism for a slitting machine. Background Technology

[0002] Polymer foam materials are lightweight, durable, and easy-to-process materials with excellent properties such as heat insulation, sound insulation, fire resistance, water resistance, and corrosion resistance. Examples include EVA foam, PE foam, TPE foam, MPP foam, and EPDM foam. With continuous technological advancements and evolving market demands, their application areas are constantly expanding and deepening, finding widespread use in fields such as construction, advertising, furniture, transportation, and packaging. In the future, polymer foam materials will play an even more advantageous role in more fields.

[0003] Currently, after the foamed board is vulcanized and shaped, it needs to be cut into different sizes by a slitting machine according to the actual process requirements. Some smaller products even need to be cut multiple times from the same substrate. Existing slitting machines usually use upper and lower pressure rollers to apply pressure to the foamed board to achieve the conveying of the foamed board. However, because the pressure rollers and the foamed board are relatively smooth, sufficient downward pressure needs to be applied to the foamed board to prevent it from slipping during the cutting process. However, because the foamed board itself has a certain degree of plasticity, this method of increasing the friction between the pressure rollers and the foamed board by increasing the downward pressure will cause the foamed board itself to be compressed due to excessive pressure, resulting in a reduction in thickness. Especially when multiple cuts are performed, the thickness of the cut products often does not meet the standards. In this case, a certain allowance for the thickness of the foamed board is usually required, which increases the production cost. At the same time, in order to meet the cutting requirements of foamed boards of different sizes, the pressure rollers of the slitting machine are often long. When cutting small-sized foamed boards, the pressure is usually applied to the middle, which can easily cause the middle of the pressure roller to bulge after long-term use. Utility Model Content

[0004] This invention addresses the problems of the prior art by providing a pressure roller mechanism for a slitting machine.

[0005] The objective of this utility model can be achieved through the following technical solution: a pressure roller mechanism for a slitting machine, comprising: a frame and an upper pressure roller and a lower pressure roller rotatably mounted on the frame, wherein the upper pressure roller has grooves on its surface and a limiting component is provided at its upper end, the limiting component includes a limiting mounting bracket fixedly mounted on the frame and a limiting roller rotatably mounted on the limiting mounting bracket, wherein two sets of limiting rollers are provided, the two sets of limiting rollers being respectively mounted on both sides of the upper end of the upper pressure roller, and a protective plate is provided at the side end of the limiting mounting bracket.

[0006] As a further improvement, a protective rod is provided on the frame, and the protective rod is located at the front end of the upper pressure roller.

[0007] As a further improvement, the surface of the limiting roller is covered with a rubber sleeve.

[0008] As a further improvement, the lower end of the limiting mounting bracket is provided with an arc-shaped clearance groove, which is correspondingly provided with the upper pressure roller.

[0009] In a further improvement, the protective plate is fixedly mounted on the limiting mounting bracket by bolts.

[0010] In a further improvement, the limiting roller is located in the middle of the upper pressure roller.

[0011] As a further improvement, the upper pressure roller has a solid internal structure.

[0012] As a further improvement, the surface of the upper pressure roller is coated with a tungsten gold coating.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In actual use, this utility model drives the upper and lower pressure rollers to rotate through an external drive source to realize the conveying and cutting of the bubble board. The grooves set on the surface of the upper pressure roller can increase the friction between the upper pressure roller and the bubble board, thereby ensuring the normal conveying of the bubble board while the pressure roller mechanism is under relatively small pressure. This effectively avoids the bubble board being compressed due to excessive pressure, thus avoiding the situation where the bubble board thickness is not up to standard and saving production costs.

[0015] 2. The upper end of the upper pressure roller of this utility model is provided with a limiting component. During the slitting process, the upper pressure roller is limited by the limiting roller to prevent the upper pressure roller from deforming due to long-term stress, which would result in the slitting bubble board being thin in the middle and thick on both sides, thus effectively extending the service life of the equipment.

[0016] 3. The present invention has a protective plate at the upper end of the upper pressure roller. The gap between the plate and the upper pressure roller is smaller than the thickness of the slit bubble board. The protective plate is used to protect the slit bubble board from being rolled into the pressure roller assembly.

[0017] 4. This utility model has a protective bar on the side where the employee operates the machine to prevent the employee's hand from being caught in the pressure roller assembly due to misoperation, thus reducing the risk of mechanical injury. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] The following describes the embodiments and appendices. Figures 1-4 The technical solution of this utility model will be further described below.

[0026] Example 1

[0027] A pressure roller mechanism for a slitting machine includes: a frame 1 and an upper pressure roller 11 and a lower pressure roller 12 rotatably mounted on the frame 1. The upper pressure roller 11 has grooves on its surface and a limit assembly 2 at its upper end. The limit assembly 2 includes a limit mounting frame 21 fixedly mounted on the frame 1 and a limit roller 22 rotatably mounted on the limit mounting frame 21. Two sets of limit rollers 22 are provided, and the two sets of limit rollers 22 are respectively located on both sides of the upper end of the upper pressure roller 11. A protective plate 3 is provided on the side end of the limit mounting frame 21.

[0028] like Figures 1-4As shown, in actual use, this utility model drives the upper and lower pressure rollers to rotate through an external drive source to achieve the conveying and cutting of the bubble sheet. The grooves on the surface of the upper pressure roller 11 can increase the friction between the upper pressure roller 11 and the bubble sheet, thereby ensuring the normal conveying of the bubble sheet while the pressure roller mechanism is under relatively low pressure. This effectively avoids the bubble sheet being compressed due to excessive pressure, thus avoiding the situation where the bubble sheet thickness does not meet the standard and saving production costs.

[0029] The upper end of the upper pressure roller 11 is provided with a limiting component 2. During the slitting process, the upper pressure roller 11 is limited by the limiting roller 22 to prevent the upper pressure roller 11 from deforming due to long-term stress, which would result in the slitting bubble board being thin in the middle and thick on both sides.

[0030] The gap between the protective plate 3 and the upper pressure roller 11 is smaller than the thickness of the slit foam board. The protective plate 3 provides protection to prevent the slit foam board from being rolled into the pressure roller assembly.

[0031] As a further preferred embodiment, a protective rod 13 is provided on the frame 1, and the protective rod 13 is located at the front end of the upper pressure roller 11.

[0032] Specifically, the protective rod 13 is installed on the side where the employee operates to prevent the employee's hand from being caught in the pressure roller assembly due to misoperation, thus reducing the risk of mechanical injury.

[0033] As a further preferred embodiment, the limiting roller 22 is covered with a rubber sleeve to reduce wear on the upper pressure roller 11 and extend the service life of the equipment.

[0034] As a further preferred embodiment, the lower end of the limiting mounting bracket 21 is provided with an arc-shaped clearance groove 211, which is correspondingly provided with the upper pressure roller 11.

[0035] As a further preferred embodiment, the protective plate 3 is fixedly mounted on the limiting mounting bracket 21 by bolts for easy installation.

[0036] As a further preferred embodiment, the limiting roller 22 is located in the middle of the upper pressure roller 11.

[0037] Specifically, such as Figure 1 and 2 As shown, the upper pressure roller 11 is limited by the limiting roller 22 to avoid deformation of the upper pressure roller 11 due to prolonged stress when cutting smaller sized foam boards, thus extending the service life of the equipment.

[0038] As a further preferred embodiment, the upper pressure roller has a solid internal structure. By replacing the traditional hollow upper pressure roller with a solid upper pressure roller, fatigue deformation during long-term use is avoided, which would result in uneven thickness of the slit foam board.

[0039] As a further preferred embodiment, the surface of the upper pressure roller is coated with a tungsten gold coating to improve the wear resistance of the upper pressure roller.

[0040] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
