DETAILED DESCRIPTION

[0026] The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, and use. It should be understood that in all of these figures, the same or similar reference numerals indicate the same or similar parts and features. The various drawings only schematically represent the concepts and principles of the embodiments of the present disclosure, and do not necessarily show the specific dimensions and proportions of the various embodiments of the present disclosure. Specific parts in specific drawings may be exaggerated to illustrate the relevant details or structures of the embodiments of the present disclosure.

[0027] See Figure 1-5 As shown, the utility model provides a rubber strip cutting machine, which specifically includes a machine platform 1, a push assembly 3 is provided on one side of the machine platform 1, a conveying platform is provided on the other side of the machine platform 1, and a strip cutting assembly 2 is provided between the conveying platform and the push assembly 3; the strip cutting assembly 2 includes a first bracket 21 spanning the machine platform 1, a material plug inlet 211 is provided at the front end of the first bracket 21, a first cylinder 22 is installed on the top of the first bracket 21, a second cylinder 24 is provided on the front and rear sides of the first cylinder 22, a connecting knife holder is provided below the first cylinder 22, and a plurality of equidistantly arranged cutting knives 2 are provided at the bottom of the connecting knife holder. 3, a pressure block 25 is provided downwardly at the movable end of the second cylinder 24; when cutting the rubber strips, the pressure block 25 cooperates with the cutter 23 to limit the rubber; the pushing assembly 3 includes a second bracket 31, on which a third cylinder 32 with its telescopic direction facing the conveyor belt is installed, and a booster plate 33 is fixedly installed at the telescopic end of the third cylinder 32, wherein the bottom end height of the booster plate 33 is higher than the top end height of the first support plate 26, so that after the processing is completed, the booster plate 33 pushes the cut rubber strips into the feeding auxiliary part 4 and then falls onto the conveying table, and does not affect the movement of the first support plate 26 during the boosting process.

[0028] In order to better limit the rubber and prevent deviation when cutting, we design two second cylinders 24 and set a pressure block 25 at the bottom of the second cylinder 24, wherein the bottom of the pressure block 25 is provided with an arc-shaped mouth 251 matching the rubber, and the two sides of the rubber are compacted after descending. The arc-shaped mouth 251 is more fitting and practical.

[0029] In order to achieve the effect of efficient strip cutting, the tool holder is fixedly connected to the bottom end of the piston rod of the first cylinder 22, and the tool holder is provided with 5 cutting knives 23 downward. Of course, the 5 cutting knives 23 here can also be 8 or 10, which can be set according to the final multiple formed. Compared with the existing single-knife single-cutting, multi-knife single-cutting achieves better efficiency; in addition, in order to cooperate with better strip cutting, a first support plate 26 is provided under the first bracket 21, and the first support plate 26 is provided with a cutting fixing groove 261 for cooperating with the cutting knife to cut strips, and the cutting fixing groove 261 is provided with 5.

[0030] In order to realize rubber strips of various sizes, we set the first support plate 26 to be replaceable. When the rubber strips are cut into different lengths, the cut fixing grooves 261 with different interval lengths are replaced. The magic female surface 262 at the bottom of the first support plate 26 cooperates with the Velcro sub-surface on the machine 1 to form a replaceable effect.

[0031] In order to achieve the effect of rubber separation and screening after cutting, as shown in the attached Figure 1 and 2 As shown in and 3, the feeding auxiliary part 4 includes a fixed clamping plate 41 arranged on the front and rear sides of the machine 1. It should be noted that the right end of the machine 1 (in the figure) has a position where the fixed clamping plate 41 can be set, and a guide plate 42 is provided between the fixed clamping plates 41. The guide plate 42 is installed on the second support plate 43 with an adjustable angle. The second support plate 43 adjusts the inclination angle by tightening the handle 44. It should be noted that the guide plate 42 is provided with at least three inclination angles, and the inclination angle of the guide plate 42 is formed by rotating the handle 44 to adjust the second support plate 43 and then supporting the guide plate 42. In this embodiment, the conveying platform is matched with at least three, therefore, the corresponding conveying platform includes a first conveying platform 5, a second conveying platform 6 and a third conveying platform 7.

[0032] Working principle:

[0033] When the utility model is in use, the first support plate is selected according to the length of the cut rubber, and the first support plate is pasted on the top of the machine table and is directly opposite to the bottom of the first cylinder. At the same time, the number of cutters on the corresponding tool holder needs to be adjusted. In this principle, 5 cutters are taken as an example. After the five cutters are installed on the tool holder, they are fixed to the piston rod of the first cylinder. Before use, the tightening handle is rotated first, and the tightening handle is rotated and the second support plate and the guide plate are adjusted to the corresponding conveying table height. Then, the rubber is inserted into the material insertion port of the first bracket of the machine table. After the second cylinders on the front and rear sides drive the second pressing blocks to fix the rubber, the first cylinder drives the tool holder and the cutter downward to cut the strips, and after the rubber is cut into rubber strips by cooperating with the cutting fixing groove of the first support plate, the third cylinder pushes the booster plate to convey the cut rubber box to the conveying table, thereby completing the effect of multiple knives cutting multiple rubber strips, accelerating the cutting efficiency, and preventing the problem of offset during processing.

[0034] The exemplary implementation scheme of the present disclosure is described in detail above with reference to the preferred embodiments. However, it can be understood by those skilled in the art that, without departing from the concept of the present disclosure, various modifications and variations can be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present disclosure can be combined in various ways without exceeding the protection scope of the present disclosure, which is determined by the attached claims.
