Description

Technical Field

[0001] This utility model relates to the field of vulcanizing machine equipment, and in particular to a vulcanizing machine feeding device. Background Technology

[0002] Vulcanizing machines are key pieces of equipment commonly used in the molding process of rubber products. Their feeding devices are typically used to transport rubber sheets and reinforcing materials such as steel strips along a predetermined path to the vulcanizing mold area, achieving synchronous feeding and stacking of multiple layers of materials. However, existing vulcanizing machine feeding devices still have many shortcomings in terms of structural layout and material guidance control.

[0003] On the one hand, traditional feeding devices often adopt a side-by-side or stacked arrangement, which not only occupies a large space, but also causes significant differences in the paths of multiple layers of materials during transportation, easily leading to problems such as asynchronous feeding and material misalignment, affecting the final product's stacking accuracy and quality stability. On the other hand, although some devices are equipped with guiding structures, the guiding form is simple and lacks effective lateral limiting and longitudinal buffer adjustment functions, resulting in poor positional stability of the rubber sheet and steel belt during transportation. Especially when the material is subjected to uneven stress or changes in thickness, it is prone to phenomena such as displacement, wrinkling, and slippage, seriously affecting the product's mold closing quality and subsequent vulcanization effect.

[0004] In addition, some existing guide structures are too rigid and cannot adapt to the changing needs of materials with different thicknesses. They pose a risk of jamming during use, have high maintenance costs, and have a narrow range of applications, making it difficult to meet the current diversified and high-precision production needs of rubber products.

[0005] Therefore, there is an urgent need for a vulcanizing machine feeding device with a compact structure, optimized feeding path, and efficient guiding and buffering adjustment capabilities to improve the feeding consistency and molding quality of rubber sheets and steel strips, and to solve the technical problems of material misalignment, unstable feeding and poor guiding effect in the existing technology.

[0028] In this embodiment, the two rubber sheets enter the vulcanizer on the upper and lower sides of the steel sheet, and a winding device is provided on the outlet side of the vulcanizer, and the winding device provides winding power; the winding device is a prior art, such as a winding device for vulcanized products of a drum vulcanizer disclosed in Application No.: CN202021858885.6; and the winding device is not an essential technical feature for solving the technical problems in this application, so it will not be described in detail in this application.

[0029] In this embodiment, a steel belt cage 5 is sleeved outside the steel coil tube 4 for stably supporting and restricting the steel belt. The steel belt cage 5 includes a first flange 51 and an annular flange 52 provided at both ends of the steel coil tube 4, and a plurality of first rollers 53 are connected between the two at a uniform circumferential spacing. The annular flange 52 is on the outside, so as to ensure that the steel sheet coil can be placed on the steel coil tube 4; the first rollers 53 are used to restrict the radial expansion of the steel belt and guide the steel belt to be smoothly released during the unfolding process, preventing curling or deviation.

[0030] To realize the tension control of the rubber sheet, a first tension roller 6 and a second tension roller 7 are provided on the mounting bracket 1. The first tension roller 6 is driven by a first synchronous belt 8 between the first rubber disk 2, and the second tension roller 7 is driven by a second synchronous belt 9 between the second rubber disk 3 to ensure that the rubber sheet maintains a stable tension when output; specifically, the ends of the first tension roller 6, the second tension roller 7, the first rubber disk 2 and the second rubber disk 3 all pass through the mounting bracket 1, and synchronous belt wheels are respectively provided at their ends, so as to realize the transmission between the first tension roller 6 and the first rubber disk 2 through the first synchronous belt 8, and the transmission between the second tension roller 7 and the second rubber disk 3 through the second synchronous belt 9.

[0031] To further improve the stability of the synchronous belt, two tension wheels 10 are further provided on the mounting bracket 1, which are respectively used to press the first synchronous belt 8 and the second synchronous belt 9 to avoid the reduction of the tension effect caused by the slack or slip of the synchronous belt.

[0032] As shown in the figure, the first rubber sheet roll is placed on the first rubber disc 2, the second rubber sheet roll is placed on the second rubber disc 3, and the steel sheet roll is wrapped around the outside of the steel coil tube 4; the first rubber sheet passes over the first tension roller 6 from below and then enters the vulcanizing machine, the second rubber sheet passes over the second tension roller 7 from above and then enters the vulcanizing machine, and the steel sheet enters the vulcanizing machine between the first rubber sheet and the second rubber sheet.

[0033] The vulcanizing machine feeding device of this utility model adopts a triangular arrangement of the first rubber disc 2, the second rubber disc 3, and the steel coil 4. By placing the steel coil 4 between the two rubber discs and staggering the discharge paths of the three, the device achieves a compact structure and facilitates synchronous feeding of three layers of materials. This realizes the technical effect of efficient and coordinated conveying of multiple layers of materials in a limited space, thereby solving the problems of dispersed structure, large space occupation, and asynchronous feeding of existing vulcanizing machine feeding devices.

[0034] Example 2

[0035] Based on the first embodiment, to further improve the positioning accuracy and stability of the rubber sheet and steel sheet during the conveying process, this embodiment optimizes the guide structure set in the feeding path. Specifically, a guide assembly 11 is introduced to achieve precise limiting adjustment of the three layers of materials in the lateral and longitudinal directions, thereby ensuring the synchronization and overlapping accuracy of the feeding process. Specifically:

[0036] As shown in the figure, a guide assembly 11 is provided on the output path. The guide assembly 11 includes two sets of first guide wheel groups 12 for lateral limiting and a second guide wheel group 13 for longitudinal limiting. The two sets of first guide wheel groups 12 are respectively on the inlet and outlet sides of the second guide wheel group 13, which are used to realize lateral and longitudinal limiting adjustment to prevent material displacement or wrinkling.

[0037] The first guide wheel assembly 12 is used to achieve lateral positioning of the material. Its structure includes a first mounting plate 14 mounted on the mounting bracket 1. The first mounting plate 14 has an upward-facing mounting groove 15. Two vertically arranged first guide wheels 16 are symmetrically spaced within the mounting groove 15. During the conveying process, the rubber sheet or steel sheet passes between the guide wheels. If the material deviates, the first guide wheels 16 can correct its lateral deviation.

[0038] The second guide wheel assembly 13 is used to achieve longitudinal limiting and buffer support for the material. It includes two oppositely arranged side plates 17, with a second guide wheel 18 laterally connected between the two side plates 17. A first spring plate 19 is installed on the top of the two side plates 17, and a second spring plate 20 is correspondingly arranged below it. The two spring plates 20 are connected by multiple vertical bolts 21, and a spring 22 is fitted on each bolt 21. The two ends of the spring 22 abut against the first spring plate 19 and the second spring plate 20 respectively, thus forming a buffered elastic structure. A third guide wheel 23 is connected to the bottom of the second spring plate 20. There is a gap between the third guide wheel 23 and the second guide wheel 18 above it to allow material to pass through. When the material is subjected to fluctuations in force or uneven thickness, the position of the third guide wheel 23 can be automatically adjusted by the spring 22 structure to avoid excessive pressure on the material or obstruction of guidance.

[0039] In one embodiment, when the second guide wheel group 13 is provided with two groups, the first guide wheel group 12 is provided with three groups, respectively at the inlet, outlet and middle positions of the second guide wheel group 13.

[0040] To improve guiding stability, two fourth guide wheels 24 are installed between the second guide wheel group 13 and the first rubber disc 2, the second rubber disc 3, and the steel coil 4. They are arranged vertically and laterally. The fourth guide wheels 24 are used to preliminarily straighten and restrict the material before it enters the second guide wheel group 13, which helps to improve the stability and feedforward control capability of the overall guiding process.

[0041] The vulcanizing machine feeding device of this utility model adopts the method of setting a first guide wheel group 12 and a second guide wheel group 13. Through the combination control of lateral limiting and longitudinal buffering guidance, it achieves the purpose of precise alignment and stable guidance of multi-layer materials in the feeding path, thereby realizing the technical effect of synchronous feeding of rubber sheet and steel belt with high overlap accuracy. It also solves the technical problems of easy material deviation, easy wrinkling and poor alignment accuracy in the traditional feeding process.
