Description

Technical Field

[0001] This utility model relates to the technical field of placing strip-shaped adhesive strips into the strip-shaped sink of a mold, and in particular to an auxiliary feeding device for placing strip-shaped adhesive strips on a mold. Background Technology

[0002] The structure of the mold used in a certain workshop is as follows: Figure 1 As shown, the mold 1 includes a plurality of strip-shaped grooves 2 on its top surface and along its length, and positioning posts 3 are fixed on the top surface of the mold 1 at its left and right ends.

[0003] The process requires that a [specific type of material] be placed in each of the strip-shaped grooves 2 of mold 1. Figures 2-3 The strip of rubber 4 is shown, and it is required that the strip of rubber 4 be exactly in the center of the strip-shaped sink 2 to complete the feeding of the strip of rubber 4. Figures 4-5 As shown, the longitudinal width of the strip rubber strip 4 is equal to the longitudinal width of the strip groove 2, the horizontal width of the strip rubber strip 4 is less than the horizontal width of the strip groove 2, and the thickness of the strip rubber strip 4 is equal to the depth of the strip groove 2. After the strip rubber strip 4 is fed, the worker controls the piston rod of the hot press to move downward. The piston rod drives the lifting plate to move downward, and the lifting plate drives multiple hot press heads to move towards each strip rubber strip 4. When the hot press head presses the strip rubber strip 4, it presses the strip rubber strip 4 into the desired shape of the product.

[0004] The method by which workers in the workshop feed multiple strip-shaped adhesive strips 4 is as follows:

[0005] S1. The worker takes out a strip of rubber 4 and places it into the first strip groove 2 of the mold 1. Then, the worker moves the strip of rubber 4 left and right. When the worker uses calipers to measure that the distance A between the left end face of the strip of rubber 4 and the left side wall of the strip groove 2 is equal to the distance B between the right end face of the strip of rubber 4 and the right side wall of the strip groove 2, the worker adjusts the strip of rubber 4 to the center of the strip groove 2, thus completing the feeding of the first strip of rubber 4. Figure 6 As shown;

[0006] S2. The worker repeats step S1 multiple times to finally complete the feeding of multiple strip rubber strips 4.

[0007] However, although the method used in the workshop can complete the feeding of multiple strips of adhesive 4, the following technical defects still exist in actual operation:

[0008] I. In step S1, after the worker puts the strip rubber 4 into the strip groove 2 of the mold 1, the worker needs to adjust the position of the strip rubber 4 multiple times in order to make the strip rubber 4 be in the center of the strip groove 2 in order to complete the feeding of the strip rubber 4. The multiple adjustments of the position of the strip rubber 4 are all done manually by the worker, which undoubtedly increases the workload of the worker.

[0009] II. There are as many as four strips of adhesive strip 4 whose positions need to be adjusted. Workers adjust the position of each strip of adhesive strip 4 one after another, which takes a long time to complete the feeding of the strips of adhesive strip 4. This undoubtedly prolongs the feeding time of the subsequent batches of strips of adhesive strip 4, which undoubtedly reduces the feeding efficiency of the strips of adhesive strip 4.

[0010] Therefore, there is an urgent need for an auxiliary feeding device that can greatly reduce the workload of workers and greatly improve the efficiency of feeding strip rubber. Utility Model Content

[0011] The purpose of this invention is to overcome the shortcomings of the prior art and provide an auxiliary feeding device for placing strips of rubber on a mold, which greatly reduces the labor intensity of workers and greatly improves the feeding efficiency of strips of rubber.

The positioning groove matches the outer contour of the strip rubber strip, and the depth of the positioning groove is equal to the thickness of the strip rubber strip.

[0015] The inner cavity of the rectangular hollow disk is connected to the branch pipe, and multiple small holes are opened on the top surface of the rectangular hollow disk, all of which are connected to the inner cavity of the rectangular hollow disk.

[0016] The diameter of the through hole in the left L-plate is equal to the diameter of the left positioning post on the mold, and the diameter of the through hole in the right L-plate is equal to the diameter of the right positioning post on the mold.

Detailed Implementation

[0046] The present invention will be further described below with reference to the accompanying drawings. The scope of protection of the present invention is not limited to the following description:

[0047] like Figures 7-15As shown, an auxiliary feeding device for placing strip-shaped rubber strips on a mold includes a left L-plate 5 and a right L-plate 6. A through hole 7 is provided in the horizontal part of the left L-plate 5. A self-locking motor 8 is fixed on the left end face of the vertical part of the left L-plate 5. The output shaft of the self-locking motor 8 passes through the vertical part of the left L-plate 5, and an upwardly extending left connecting plate 9 is connected to the extended end. A through hole 7 is provided in the horizontal part of the right L-plate 6. A rotating shaft 10 is rotatably installed in the vertical part of the right L-plate 6. An upwardly extending right connecting plate 11 is fixed on the inner end of the rotating shaft 10. A bearing hole is provided in the vertical part of the right L-plate 6, and the rotating shaft 10 is rotatably installed in the bearing hole.

[0048] A concave part 12 with an upward opening is fixed between the left connecting plate 9 and the right connecting plate 11. A flat plate 13 is fixed on the top surface of the concave part 12. Multiple rectangular through slots 14 spaced apart are formed in the flat plate 13 along its length. Four rectangular through slots 14 are formed in the flat plate 13 along its length. A feed cylinder 15 is fixed on the bottom wall of the concave part 12. The left and right ends of the flat plate 13 are welded to the left and right side walls of the concave part 12.

[0049] The piston rod of the feed cylinder 15 passes through the bottom wall of the concave part 12 and extends into the opening of the concave part 12. The top of the piston rod of the feed cylinder 15 is fixed with a main pipe 16. The left end of the main pipe 16 is closed. A vacuum pump is connected to the right end of the main pipe 16. Multiple branch pipes 17 corresponding to each rectangular through groove 14 are fixed along the length of the main pipe 16. A rectangular hollow disk 18 that slides with the rectangular through groove 14 is fixed on the top wall of the branch pipe 17. A positioning groove 19 is formed between the top surface of the rectangular hollow disk 18 and the inner wall of the rectangular through groove 14. The positioning groove 19 matches the outer contour of the strip rubber strip 4, and the depth of the positioning groove 19 is equal to the thickness of the strip rubber strip 4.

[0050] The inner cavity 20 of the rectangular hollow disk 18 is connected to the branch pipe 17. Multiple small holes 21 are opened on the top surface of the rectangular hollow disk 18, and all the small holes 21 are connected to the inner cavity 20 of the rectangular hollow disk 18.

[0051] The diameter of the through hole 7 in the left L-plate 5 is equal to the diameter of the left positioning post 3 on the mold 1, and the diameter of the through hole 7 in the right L-plate 6 is equal to the diameter of the right positioning post 3 on the mold 1. The left connecting plate 9 and the right connecting plate 11 are parallel, and both the left connecting plate 9 and the right connecting plate 11 are connected to the concave part 12 by locking screws.

[0052] The working process of this utility model is as follows:

[0053] S1, the workers will be as follows Figure 1 The mold 1 shown is placed flat on the table surface;

[0054] S2. Position and install the auxiliary feeding device on mold 1:

[0055] The worker holds the left L-plate 5 and right L-plate 6 of the auxiliary feeding device with both hands, then fits the through hole 7 of the left L-plate 5 onto the positioning post 3 located on the left side of the mold 1. Simultaneously, the worker fits the through hole 7 of the right L-plate 6 onto the positioning post 3 located on the right side of the mold 1. Then, the horizontal portions of both the left L-plate 5 and the right L-plate 6 are supported on the top surface of the mold 1, thus achieving the positioning and installation of the auxiliary feeding device on the mold 1. Figure 16 As shown, at this time, the four positioning slots 19 of the auxiliary feeding device are respectively located directly above the four strip-shaped sinks 2 of the mold 1;

[0056] S3. Position the four strip adhesive strips 4 within the auxiliary feeding device:

[0057] The worker took out four such Figures 2-3 The strip of adhesive 4 shown is placed into four positioning grooves 19 respectively. Since the positioning grooves 19 match the outer contour of the strip of adhesive 4, and the depth of the positioning grooves 19 is equal to the thickness of the strip of adhesive 4, the four strips of adhesive 4 are thus positioned within the auxiliary feeding device. Figures 17-18 As shown, at this time, the strip 4 is directly above the center of the strip groove 2 in the mold 1;

[0058] S4. Secure the four strips of adhesive 4 by adsorption:

[0059] The worker controls the vacuum pump to start, and the vacuum pump evacuates the main pipe 16, branch pipe 17, the inner cavity 20 of the rectangular hollow disk 18 and the small hole 21. Under negative pressure, the strip adhesive strip 4 is adsorbed and fixed on the rectangular hollow disk 18, thus realizing the adsorption and fixation of the four strip adhesive strips 4.

[0060] S5. The self-locking motor 8 is started, which drives the left connecting plate 9 to rotate. The left connecting plate 9 drives the concave part 12 to rotate, and the concave part 12 drives the feed cylinder 15, plate 13, vacuum pump, main pipe 16 and rectangular hollow disk 18 to rotate synchronously. This, in turn, drives the strip adhesive strip 4 that is adsorbed and fixed to rotate synchronously. When the strip adhesive strip 4 has rotated 180°, the controller controls the self-locking motor 8 to turn off. At this time, the four strip adhesive strips 4 are respectively facing the four strip grooves 2 of the mold 1, as shown. Figure 19 As shown;

[0061] S6. The piston rod of the feed cylinder 15 extends downward, causing the main pipe 16 to move downward. The main pipe 16 then causes the branch pipe 17 to move downward synchronously. The branch pipe 17 then causes the rectangular hollow disc 18 to move downward synchronously. The rectangular hollow disc 18 causes the strip of adhesive 4, which is adsorbed and fixed, to move towards the strip-shaped sink 2. When the piston rod of the feed cylinder 15 is fully extended, the strip of adhesive 4 just enters the strip-shaped sink 2. Figure 20 As shown, the bottom surface of the strip 4 is in contact with the bottom of the strip trough 2;

[0062] S7. The worker controls the vacuum pump to shut off, and the rectangular hollow disc 18 no longer adheres to and fixes the strip adhesive 4; then, the piston rod of the feed cylinder 15 is controlled to retract upwards, driving the main pipe 16 to move upwards. The main pipe 16 drives the branch pipe 17 and the rectangular hollow disc 18 to move upwards synchronously. When the piston rod of the feed cylinder 15 is fully retracted, the rectangular hollow disc 18 returns to its original position. Figure 21 As shown;

[0063] S8. The worker removes the left L-plate 5 and right L-plate 6 of the auxiliary feeding device from the mold 1, thus finally realizing the feeding of the four strip rubber strips 4. After feeding, as... Figures 4-5 As shown;

[0064] In steps S2 to S8, the worker only needs to first position and install the auxiliary feeding device on the mold 1, and then position the four strip rubber strips 4 in the auxiliary feeding device. Then, through the linkage of the self-locking motor 8, the feeding cylinder 15 and the vacuum pump, the feeding of the four strip rubber strips 4 can be completed quickly. At this time, the strip rubber strips 4 are exactly in the center of the strip sink 2.

[0065] Therefore, compared with the feeding method in the workshop, this auxiliary feeding device does not require workers to adjust the position of the strip rubber 4 multiple times in order to complete the feeding of the strip rubber 4. Instead, the strip rubber 4 only needs to be placed into the positioning groove 19 first, and then the four strip rubber 4 can be quickly fed through the linkage of the self-locking motor 8, the feeding cylinder 15 and the vacuum pump, thereby greatly reducing the workload of the workers.

[0066] In addition, this auxiliary feeding device can feed four strips of adhesive strip 4 at the same time without the need for workers to feed them one by one, thus not prolonging the feeding time for subsequent batches of strips of adhesive strip 4, and thus greatly improving the feeding efficiency of strips of adhesive strip 4.

[0067] S9. After the strip rubber strip 4 is fed, the worker controls the piston rod of the hot press to move downward. The piston rod drives the lifting plate to move downward. The lifting plate drives multiple hot press heads to move towards each strip rubber strip 4 respectively. When the hot press head presses the strip rubber strip 4, the hot press head presses the strip rubber strip 4 into the desired product shape.

[0068] S10. Workers can repeat steps S2 to S9 multiple times to complete the feeding of multiple batches of strip rubber strips 4 and press out the corresponding products of the required shapes.
