Description

Technical Field

[0001] The invention belongs to the technical field of rubber product processing, and particularly relates to an integrated guiding and caching device for a rubber product production line. Background Art

[0002] At present, in the production and processing of rubber products (rubber belts), it is necessary to add corresponding receiving and sending mechanisms at the entry and exit ends of each process to meet the connection between various processes in the assembly line operation.

[0003] However, in the process of receiving and sending out each process, the structure used only plays the role of transmission guidance. Once a problem occurs in a process or online maintenance is required, the machine must be stopped for processing. As a result, the following technical defects exist:

[0004] 1. When a problem occurs in one process, the adjacent processes must also be shut down, which may directly cause production to stop and affect product production efficiency;

[0005] 2. The structure of receiving and sending out has a single role and cannot achieve the technical purpose of caching. Therefore, the adaptability is poor. Of course, if a cache device is added between two adjacent processes, it will inevitably lead to an increase in production costs, and once the line is broken, it will be more difficult to operate. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an improved integrated guiding and caching device for a rubber product production line.

[0007] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0008] A guiding and caching integrated device for a rubber product production line comprises a guiding mechanism and a caching mechanism arranged between two adjacent processes for guiding rubber products, wherein a transmission roller is provided at the receiving end of each process, the guiding mechanism comprises a first guiding roller group and a second guiding roller group respectively arranged on a machine frame of each process and flipped upward around a horizontal direction, wherein a gap is formed between the first guiding roller group and the second guiding roller group; the caching mechanism comprises a first buffer roller group and a second buffer roller group respectively arranged on the first guiding roller group and the second guiding roller group and synchronously supporting the rubber products upward as the first guiding roller group and the second guiding roller group flip, wherein after the first buffer roller group and the second buffer roller group are respectively higher than the corresponding first guiding roller group and the second guiding roller group, the rubber products are cached between the two processes through the gap.

[0009] Preferably, the first guide roller group and the second guide roller group are symmetrically arranged about the notch; the first buffer roller group and the second buffer roller group are symmetrically arranged about the notch, which facilitates layout and assembly, as well as synchronous control.

[0010] According to a specific embodiment and preferred aspect of the present invention, the first guide roller assembly includes a first feed frame, a first feed roller, and a first supporting rod; the second guide roller assembly includes a second feed frame, a second feed roller, and a second supporting rod, wherein the first feed frame and the second feed frame are respectively connected to the frames of two adjacent processes by pivoting along the length of the transmission roller, and the first feed frame and the second feed frame are separated by a gap away from the end of the pivot; the first feed roller and the second feed roller are respectively spaced apart on the first feed frame and the second feed frame along the transmission direction of the rubber product, and the first supporting rod and the second supporting rod are respectively telescopically adjustable along their own lengths and are respectively supported between the first feed frame and the frame on the corresponding side and between the second feed frame and the frame on the corresponding side, facilitating the implementation of flipping motion adjustment.

[0011] Preferably, the first feed rack includes first arms located on either side, a first feed roller located between the two first arms, a first top support rod corresponding to the first arms and disposed below the first arms, and two ends of the first top support rod connected between the first feed rack and the frame, with the connection points at the two ends of the first top support rod and the pivot point of the first feed rack forming a triangle. The second feed rack includes second arms located on either side, the second feed roller located between the two second arms, a second top support rod corresponding to the second arms and disposed below the second arms, and two ends of the second top support rod connected between the second feed rack and the frame, with the connection points at the two ends of the second top support rod and the pivot point of the second feed rack forming a triangle. Stable adjustment and support are achieved under changes in the length of the corresponding triangular supports and triangular arms.

[0012] According to another specific implementation and preferred aspect of the present invention, the first buffer roller group includes a first support roller group and a first pressure roller group, and the second buffer roller group includes a second support roller group and a second pressure roller group, wherein the first support roller group and the second support roller group respectively lift the rubber product in the upper and lower directions, and the first pressure roller group and the second pressure roller group are close to the transmission rollers of each process and are pressed on the rubber product by their own weight. The cooperation of one pushing and one pressing allows the rubber product to fit the rollers for transmission and buffering.

[0013] According to another specific embodiment and preferred aspect of the present invention, the first and second support roller groups are respectively configured to be telescopically adjustable in a direction perpendicular to the first and second feed racks, and the telescopic amounts are proportional to the tilting angles of the corresponding first and second feed racks. In other words, the gap can be covered for short-distance buffering as needed, or the products can be buffered from the gap to between two processes for stacking and buffering as needed.

[0014] Preferably, the integrated guiding and caching device also includes an angle sensor arranged on the pivot and used to monitor the flipping angle of the first feeding rack and the second feeding rack, and a control processor connected to the first cache roller group and the second cache roller group, wherein the angle sensor is connected to the control processor.

[0015] Preferably, the first support roller group includes a first support roller horizontally arranged between the two first arms and parallel to the first feeding roller, and a first telescopic cylinder respectively arranged on the first arms and driving the first support roller to move up and down in the up and down directions; the second support roller group includes a second support roller horizontally arranged between the two second arms and parallel to the second feeding roller, and a second telescopic cylinder respectively arranged on the second arms and driving the second support roller to move up and down in the up and down directions.

[0016] Furthermore, the first pressing roller group includes a first pressing roller and a first arm rod for freely rotating the two ends of the first pressing roller and connecting them to the frame; the second pressing roller group includes a second pressing roller and a second arm rod for freely rotating the two ends of the second pressing roller and connecting them to the frame.

[0017] In addition, the guiding mechanism and the cache mechanism form a transmission mode and a cache mode. When in the transmission mode, the first feed roller and the second feed roller are arranged flush, and the first top support roller and the second top support roller are respectively located below the roller conveying surface formed by the first feed roller and the second feed roller; the cache mode includes a first cache state and a second cache state. When in the first cache state, the first feed rack and the second feed rack are respectively flipped upward to open the gap, the first top support roller is located between the top and bottom first feed rollers, and the second top support roller is located between the top and bottom second feed rollers, and the rubber product spans above the gap; when in the second cache state, the gap becomes larger, and the first top support roller and the second top support roller respectively rise to the side and above the top first feed roller and the second feed roller, and the rubber product falls from the gap into the space between two adjacent processes for cache.

[0018] Due to the implementation of the above technical solution, the present invention has the following advantages compared with the prior art:

[0019] The present invention, through the synchronous cooperation of guiding and caching, can not only implement the rubber product covering the notch and arching in the tensioning mode, thereby meeting the caching and transmission needs of rubber products with a small cache volume; but also can cache the rubber product from the notch to between two adjacent processes through the high-position guidance of the cache roller, thereby meeting the caching and transmission needs of rubber products with a large cache volume. Therefore, not only the guiding function is increased, but also different caching methods can be selected according to the needs of large and small cache volumes, thereby increasing the adaptability of the integrated device. In addition, the structure is simple, the implementation is convenient, and the cost is low. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] like Figures 1 to 3 As shown, the integrated guiding and caching device of the rubber product production line includes a guiding mechanism 1 and a caching mechanism 2 arranged between two adjacent processes for guiding the rubber products. In this example, the rubber product takes the rubber strip D as an example, and the specific structure of the equipment used is as follows.

[0032] In this example, a conveying roller G is provided at the transfer end of each process.

[0033] The guiding mechanism 1 includes a first guiding roller group 11 and a second guiding roller group 12 which are respectively turned upward around the horizontal direction and arranged on the frame J of each process, wherein a gap is formed between the first guiding roller group 11 and the second guiding roller group 12.

[0034] The buffer mechanism 2 includes a first buffer roller group 21 and a second buffer roller group 22 which are respectively arranged on the first guide roller group 11 and the second guide roller group 12 and synchronously support the rubber product upward as the first guide roller group 11 and the second guide roller group 12 turn over.

[0035] Specifically, the first guide roller group 11 and the second guide roller group 12 are symmetrically arranged about the notch; the first buffer roller group 21 and the second buffer roller group 22 are symmetrically arranged about the notch, which facilitates layout and assembly, as well as synchronous control.

[0036] The first guide roller assembly 11 includes a first feeding frame 110 , a first feeding roller 111 , and a first supporting rod 112 .

[0037] The second guide roller assembly 12 includes a second feeding frame 120 , a second feeding roller 121 , and a second supporting rod 122 .

[0038] The first feeding rack 110 and the second feeding rack 120 are respectively connected to the racks J of two adjacent processes by pivoting along the length direction of the transmission roller G, and a gap is formed between the first feeding rack 110 and the second feeding rack 120 away from the pivot end.

[0039] The first feeding roller 111 and the second feeding roller 121 are respectively spaced apart and distributed on the first feeding rack 110 and the second feeding rack 120 along the transmission direction of the rubber product.

[0040] The first supporting rod 112 and the second supporting rod 122 are respectively adjusted to be telescopic along their own length direction, and are respectively supported between the first feeding rack 110 and the frame J, and between the second feeding rack 120 and the frame J on the corresponding side, so as to facilitate the implementation of the flipping movement adjustment.

[0041] The first feeding rack 110 includes first arms a located on both sides, the first feeding roller 111 is located between the two first arms a, and the first supporting rod 112 corresponds to the first arms a one-to-one and is arranged below the first arms a.

[0042] In this example, both ends of the first supporting rod 112 are respectively connected between the first feeding rack 110 and the frame J, and a triangle is formed by the connection points at both ends of the first supporting rod 112 and the turning point of the first feeding rack 110.

[0043] In this example, the first supporting rod 112 is a double-headed telescopic cylinder.

[0044] The second feeding rack 120 includes second arms b located on both sides, and the second feeding roller 121 is located between the two second arms b.

[0045] The second supporting rod 122 corresponds to the second arm b and is located below the second arm b. The two ends of the second supporting rod 122 are connected between the second feeder 120 and the frame J. A triangle is formed by the connection points of the second supporting rod 122 and the pivot point of the second feeder 120. This allows for stable adjustment and support under varying lengths of the corresponding triangular supports and triangular arms.

[0046] In this example, the second supporting rod 122 is a double-headed telescopic cylinder.

[0047] The first buffer roller group 21 includes a first supporting roller group 210 and a first pressing roller group 211 , and the second buffer roller group 22 includes a second supporting roller group 220 and a second pressing roller group 221 .

[0048] The first supporting roller group 210 and the second supporting roller group 220 respectively lift the rubber product in a direction perpendicular to the first feeding rack 110 and the second feeding rack 120 .

[0049] The first pressing roller group 211 and the second pressing roller group 221 are close to the transmission roller G of each process and are placed on the rubber product by their own weight. The cooperation of one pressing and one pressing makes the rubber product fit the rollers for transmission and buffering.

[0050] The first support roller assembly 210 and the second support roller assembly 220 are respectively arranged to be telescopically adjustable in a direction perpendicular to the first feed rack 110 and the second feed rack 120, and the amount of telescopic adjustment is proportional to the tilting angle of the corresponding first feed rack 110 and the second feed rack 120. In other words, the gap can be covered for short-distance buffering as needed, or the products can be buffered from the gap to between two processes for stacking and buffering as needed.

[0051] Specifically, the first supporting roller group 210 includes a first supporting roller d1 horizontally arranged between the two first arms a and parallel to the first feeding roller 111, and a first telescopic cylinder d2 respectively arranged on the first arms a and driving the first supporting roller d1 to move up and down in a direction perpendicular to the first arms a. That is to say, combined with the projection of the main view, it can be seen that in the projection plane, the telescopic direction of the first telescopic cylinder d2 is perpendicular to the length direction of the first supporting roller d1.

[0052] The second support roller assembly 220 includes a second support roller d3, which is disposed transversely between the two second arms b and parallel to the second feed roller 121, and second telescopic cylinders d4, which are mounted on the second arms b and drive the second support roller d3 to move vertically. In other words, as can be seen from the projection of the front view, the extension and retraction directions of the second telescopic cylinders d4 are perpendicular to the longitudinal direction of the second support roller d3 within the projection plane.

[0053] The first pressing roller group 211 includes a first pressing roller y1 and a first arm y2 for connecting both ends of the first pressing roller y1 to the frame J for free rotation.

[0054] The second pressing roller group 222 includes a second pressing roller y3 and a second arm y4 for connecting the two ends of the second pressing roller y3 to the frame J for free rotation.

[0055] In addition, in order to facilitate the effective control of angles and telescopic displacements, in this example, the integrated guiding and caching device also includes an angle sensor arranged on a pivot and used to monitor the flipping angles of the first feeding rack 110 and the second feeding rack 120, and a control processor connected to the first cache roller group 21 and the second cache roller group 22, wherein the angle sensor is connected to the control processor.

[0056] At the same time, in this example, by providing a telescopic rod that can be horizontally extended and retracted at the lower part of the frame J, the diagonal support stroke of the double-headed telescopic cylinder is further increased, the lifting height is increased, and the gap is expanded to facilitate caching.

[0057] Specifically, a first telescopic rod s1 capable of telescopically pushing the bottom of the first supporting rod 112 and a second telescopic rod s2 capable of telescopically pushing the bottom of the second supporting rod 122 are provided at the lower part of the frame J, wherein the first telescopic rod s1 and the second telescopic rod s2 respectively push the triangle to flip around the pivot.

[0058] In summary, the implementation process of this embodiment is as follows:

[0059] See again Figure 1 As shown, when in the transmission mode, the first feed roller 111 and the second feed roller 121 are arranged flush, and the first support roller d1 and the second support roller d3 are respectively located below the roller conveying surface formed by the first feed roller 111 and the second feed roller 121. At this time, the rubber strip D passes smoothly through each roller and is transmitted between the two processes.

[0060] See again Figure 2As shown, the first feeding rack 110 and the second feeding rack 120 are respectively flipped upward to open the gap, the first supporting roller d1 is located between the top and bottom first feeding rollers 111, the second supporting roller d3 is located between the top and bottom second feeding rollers 121, and the rubber strip D spans over the gap. Therefore, the rubber strip D can cover the gap and arch in the tensioning mode, meeting the caching and transmission needs of the rubber strip D with a small buffer volume.

[0061] See again Figure 3 As shown, in Figure 2 On the basis of this, if the gap continues to become larger, the first top support roller d1 and the second top support roller d3 rise to the upper side of the first feeding roller 111 and the second feeding roller 121 at the top respectively, and the rubber strip D falls from the gap into the space between two adjacent processes for caching. Therefore, the rubber strip D can be cached from the gap to the space between two adjacent processes through the high-position guidance of the cache roller, meeting the caching and transmission needs of the rubber strip D with a large cache volume. The structure is simple and the implementation is convenient.

[0062] In summary, this embodiment has the following advantages:

[0063] 1. Under the setting of the flip angle and the expansion ratio, through the synchronous cooperation of guiding and caching, not only can the rubber product cover the notch and arch in the tensioning mode, so as to meet the caching and transmission needs of rubber products with a small buffer volume; but also the rubber product can be cached from the notch to between two adjacent processes through the high-position guidance of the buffer roller, so as to meet the caching and transmission needs of rubber products with a large buffer volume. Therefore, not only the guiding function is increased, but also different caching methods can be selected according to the needs of the large and small buffer volumes, thereby increasing the adaptability of the integrated device. In addition, the structure is simple, the implementation is convenient, and the cost is low.

[0064] 2. The stability of the overall structure is improved through triangular deformation and support. At the same time, with the assistance of the telescopic rod, the diagonal support stroke of the double-headed telescopic cylinder is further increased, the jacking height is increased, and the gap is expanded to facilitate caching.

[0065] The above detailed description of the present invention is intended to enable persons familiar with the art to understand the contents of the present invention and implement them. It does not limit the scope of protection of the present invention. Any equivalent changes or modifications made based on the spirit of the present invention should be included in the scope of protection of the present invention.
