Description

Technical Field

[0001] This utility model relates to a splicing machine, specifically, to a splicing machine for rubber products. Background Technology

[0002] Rubber is a highly elastic polymer material with reversible deformation. It can undergo large deformation under a small external force and return to its original shape after the external force is removed. Thanks to the excellent properties of rubber, the application of rubber products is becoming increasingly widespread. In the production process of rubber products, some rubber products cannot directly meet the usage requirements after production. For example, segmented rubber products need to be spliced ​​by a splicing machine in subsequent processing to form longer products to meet usage requirements. This operation requires the use of a special rubber product splicing machine. During the splicing process, two rubber products need to be clamped and their ends brought into contact with each other. Then, the rubber products are heated by the splicing machine to fuse them together, and then cooled to complete the splicing process.

[0003] Existing rubber product splicing machines often result in burns to workers when removing the heated rubber products, making the process inconvenient. To prevent burns, the rubber products are typically cooled after splicing, requiring a long cooling process that impacts splicing efficiency. Therefore, we propose a new rubber product splicing machine. Utility Model Content

[0004] The purpose of this invention is to provide a splicing machine for rubber products, so as to solve the problem mentioned in the background art that the long cooling time of rubber products leads to a decrease in splicing efficiency.

[0005] To address the aforementioned problems, the present invention aims to provide a splicing machine for rubber products, comprising a base, a mounting frame fixedly connected to the upper side of the base, a heating component mounted on the mounting frame for heating the rubber product, two positioning mechanisms located near the sides of the mounting frame, with the heating component positioned between the two positioning mechanisms for fixing the position of the rubber product, and a material guiding mechanism on the upper side of the base for lifting and guiding the movement of the rubber product. The material guiding mechanism includes several rotating plates hinged to the upper side of the base. When the positioning mechanisms release the fixing of the rubber product, they drive the rotating plates to rotate away from the base. The rotating plates drive the rubber product upward, and under the guidance of the rotating plates, the rubber product slides along the surface of the rotating plates.

[0006] As a further improvement to this technical solution, two fixing rods are fixedly connected to the upper side of the base away from the hinge of the rotating plate, and a stop bar is fixedly connected to the upper end of the two fixing rods, the stop bar restricting the rotation angle of the rotating plate.

[0007] As a further improvement to this technical solution, two support brackets are fixedly connected to one side of the base near the top, with a gap between the two support brackets. A buffer pad is fixedly connected to the bottom of the support bracket, and a rubber product that slides along the surface of the rotating plate enters the interior of the support bracket.

[0008] As a further improvement to this technical solution, an installation groove is provided on one side of the base near the top. A cold air blower is fixedly connected inside the installation groove. The cold air blower is located in the gap between the two support brackets. When the rubber product enters the interior of the support bracket, the cold air blower blows air onto the rubber product.

[0009] As a further improvement to this technical solution, the heating assembly includes a second electric push rod fixedly connected to the upper side of the mounting bracket near the center. The push rod of the second electric push rod passes through the top of the mounting bracket and is fixedly connected to an upper heater. A lower heater is fixedly connected to the upper side of the base near the center. The bottom shape of the upper heater matches the top shape of the lower heater. During the extension and retraction of the push rod of the second electric push rod, the upper heater moves upward or downward.

[0010] As a further improvement to this technical solution, the positioning mechanism includes a first electric push rod fixedly connected to the upper side of the mounting frame. The push rod of the first electric push rod passes through the top of the mounting frame and is fixedly connected to an upper positioning frame. During the extension and retraction process, the push rod of the first electric push rod drives the upper positioning frame to move upward or downward.

[0011] As a further improvement to this technical solution, the positioning mechanism also includes a lower positioning frame fixedly connected to the upper side of the base. The lower heater and the top of the two lower positioning frames are inclined downwards at the ends away from the mounting frame, and the bottom shape of the upper positioning frame is adapted to the top shape of the lower positioning frame.

[0012] As a further improvement to this technical solution, the upper positioning frame is located between two rotating plates. Two L-shaped mounting rods are fixedly connected to the opposite side walls of the upper positioning frame. The end of the mounting rod away from the upper positioning frame is connected to an upper magnetic block through a hinge. A lower magnetic block is fixedly connected to the upper side of the rotating plate at a position corresponding to the upper magnetic block. The upper and lower magnetic blocks are attracted to each other. During the upward movement of the upper positioning frame, the magnetic attraction of the upper and lower magnetic blocks drives the rotating plate to rotate around the hinge point with the base.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This splicing machine for rubber products, after the rubber products are spliced, the first and second electric push rods drive the upper positioning frame and upper heater to move upward. The upper positioning frame drives the rotating plate to rotate upward through the mounting rod and magnetic block, which in turn moves the rubber products upward. Under the guidance of the rotating plate, the rubber products move into the interior of the support frame. Subsequently, the cold air fan cools the rubber products. Through the material guiding mechanism, the rubber products can be automatically moved away from the heating station and into the cooling area after splicing. There is no need for the staff to wait for the rubber products to cool down before manually removing them, which shortens the time interval from the completion of splicing to the next round of operation. At the same time, by guiding the rubber products to be placed on the support frame, during the cooling process of the rubber products, the staff can place the next set of rubber products to be spliced ​​on the positioning mechanism for fixation, which speeds up the overall splicing speed of the rubber products.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1 Please see Figure 1 and Figure 2 As shown, the purpose of this embodiment is to provide a splicing machine for rubber products, including a base 1, a mounting frame 11 fixedly connected to the upper side of the base 1, a heating component on the mounting frame 11 for heating the rubber products, two positioning mechanisms 2 near the sides of the mounting frame 11, the heating component being located between the two positioning mechanisms 2, the positioning mechanisms 2 for fixing the position of the rubber products, a material guiding mechanism 3 on the upper side of the base 1 for lifting and guiding the movement of the rubber products, the heating component including a second electric push rod 12 fixedly connected to the upper side of the mounting frame 11 near the middle, the push rod of the second electric push rod 12 passing through the top of the mounting frame 11 and fixedly connected to an upper heater 13, a lower heater 14 fixedly connected to the upper side of the base 1 near the middle, the bottom shape of the upper heater 13 matching the top shape of the lower heater 14, the push rod of the second electric push rod 12 driving the upper heater 13 to move upward or downward during extension and retraction, both the upper heater 13 and the lower heater 14 are electric heaters, electric heaters are existing technology, this solution does not improve upon them, and will not be described here; During the connection of rubber products, the worker places two rubber products inside the positioning mechanism 2 and the two rubber products abut against each other. The abutment point of the two rubber products is located on the lower heater 14. Then the worker fixes the two rubber products through the two positioning mechanisms 2. After the rubber products are fixed, the push rod of the second electric push rod 12 extends and drives the upper heater 13 to move downward so that it abuts against the top of the lower heater 14. The upper heater 13 and the lower heater 14 heat the two rubber products to connect them together.

[0018] refer to Figure 3 The positioning mechanism 2 includes a first electric push rod 21 fixedly connected to the upper side of the mounting frame 11, and a second electric push rod 12 in the middle of the two first electric push rods 21. The push rod of the first electric push rod 21 passes through the top of the mounting frame 11 and is fixedly connected to the upper positioning frame 22. During the extension and retraction process, the push rod of the first electric push rod 21 drives the upper positioning frame 22 to move up or down. The positioning mechanism 2 also includes a lower positioning frame 24 fixedly connected to the upper side of the base 1. The bottom shape of the upper positioning frame 22 is adapted to the top shape of the lower positioning frame 24. The lower heater 14 and the two lower positioning frames 24 are inclined downward at the ends away from the mounting frame 11. When the rubber product rises a small distance, it can move from the inside of the lower heater 14 and the lower positioning frame 24 to the outside, so that the connected rubber product can be moved out from the inside of the lower heater 14 and the lower positioning frame 24.

[0019] When the upper positioning frame 22 and the lower positioning frame 24 are joined together, a clamping groove is formed between them. The rubber product is located inside the clamping groove. By bringing the upper positioning frame 22 and the lower positioning frame 24 closer to each other, the rubber product inside the clamping groove is clamped and fixed. When the upper positioning frame 22 and the lower positioning frame 24 are separated, the upper positioning frame 22 releases the fixation on the rubber product, making the rubber product on the lower positioning frame 24 movable, which facilitates the subsequent removal of the rubber product.

[0020] To prevent workers from being burned by high-temperature rubber products, and to speed up the assembly of rubber products, refer to Figure 4 - Figure 6 The material guiding mechanism 3 includes several rotating plates 31 hinged to the upper side of the base 1. The upper positioning frame 22 is located between two of the rotating plates 31. Two L-shaped mounting rods 23 are fixedly connected to the opposite side walls of the upper positioning frame 22. The end of the mounting rod 23 away from the upper positioning frame 22 is connected to an upper magnetic block 25 through a hinge. The upper magnetic block 25 can be flipped at a small angle at the end of the mounting rod 23. A lower magnetic block 34 is fixedly connected to the upper side of the rotating plate 31 at the position corresponding to the upper magnetic block 25. When the upper positioning frame 22 and the lower positioning frame 24 are in contact with each other to fix the rubber product, the upper magnetic block 25 and the lower magnetic block 34 are attracted to each other. When the positioning mechanism 2 releases the fixation of the rubber product, the upper positioning frame 22 moves upward and drives the rotating plate 31 to rotate around the hinge point with the base 1 through the magnetic attraction of the upper magnetic block 25 and the lower magnetic block 34.

[0021] Specifically, the upper positioning frame 22 drives the upper magnetic block 25 to move upward. During the movement of the upper magnetic block 25, the magnetic attraction between the upper magnetic block 25 and the lower magnetic block 34 causes one end of the rotating plate 31 to move away from the base 1. At this time, the other end of the rotating plate 31 rotates around the position hinged to the base 1. The rotating plate 31 lifts the rubber product, causing it to move upward. The moving rubber product gradually separates from the lower positioning frame 24 and the lower heater 14. After the rubber product leaves the lower positioning frame 24 and the lower heater 14, it slides along the surface of the rotating plate 31 under the guidance of the rotating plate 31.

[0022] Two support brackets 33 are fixedly connected to one side of the base 1 near the top. The top of the support brackets 33 is inclined away from the base 1 to increase the distance between the top of the support brackets 33 and the side wall of the base 1, making it easier for rubber products to fall into the interior of the support brackets 33. A gap is left between the two support brackets 33. A buffer pad is fixedly connected to the bottom of the support brackets 33 to buffer the impact force of the rubber products falling into the interior of the support brackets 33, so as to avoid the rubber products breaking or separating due to large impact force. The rubber products sliding along the surface of the rotating plate 31 enter the interior of the support brackets 33 and are placed on the base 1. An installation slot is provided on one side near the top, and a cooler 15 is fixedly connected inside the installation slot. The cooler 15 is located in the gap between the two support brackets 33 and below the lower heater 14. When the rubber product enters the interior of the support bracket 33, the joint of the rubber product corresponds to the position of the cooler 15. The cooler 15 blows air onto the rubber product, and the high temperature at the joint of the rubber product is carried away by the gas, so that the joint of the rubber product is cooled and cured. On the one hand, it accelerates the curing and connection between the two rubber products, and on the other hand, it prevents the staff from being burned by the high temperature when removing the rubber product.

[0023] To separate the upper magnetic block 25 and the lower magnetic block 34, facilitating the jointing of new rubber products, two fixed rods are fixedly connected to the upper side of the base 1, away from the hinge point of the rotating plate 31. A stop bar 32 is fixedly connected to the upper end of each rod, limiting the rotation angle of the rotating plate 31. When the rotating plate 31 contacts the stop bar 32, the plate stops rotating under the constraint of the stop bar 32. At this time, the upper magnetic block 25 continues to rise along with the upper positioning frame 22. During this process... With the rotating plate 31 and the lower magnetic block 34 in a stationary state, while the upper positioning frame 22 and the upper magnetic block 25 are in a moving state, the pulling force between the upper magnetic block 25 and the lower magnetic block 34 gradually increases. When the force pulling the upper magnetic block 25 and the lower magnetic block 34 is greater than the magnetic force between the upper magnetic block 25 and the lower magnetic block 34, the upper magnetic block 25 and the lower magnetic block 34 separate. At this time, the upper positioning frame 22 continues to move upward, while the rotating plate 31 and the lower magnetic block 34 rotate to the horizontal direction under the action of gravity to reset.

[0024] In order to facilitate the rotation of the rotating plate 31 and also to limit the rotation angle of the rotating plate 31, the end of the rotating plate 31 away from the stop bar 32 is set as an upward inclined surface. When the rotating plate 31 and the stop bar 32 are in contact, the inclined surface of the rotating plate 31 is in contact with the top of the base 1. When using this device: In the initial state, the bottom of the rotating plate 31 is attached to the upper side of the base 1, and the push rods of the first electric push rod 21 and the second electric push rod 12 retract, causing the upper positioning frame 22 and the upper heater 13 to be located away from the base 1. During the splicing of rubber products, the workers place two rubber products on two lower positioning frames 24 respectively, so that the two ends of the two rubber products abut against the lower heater 14. Then, the push rod of the first electric push rod 21 extends and drives the upper positioning frame 22 to move downward, so that the upper positioning frame 22 cooperates with the lower positioning frame 24 to fix the rubber products. After the rubber products are fixed, the push rod of the second electric push rod 12 drives the upper heater 13 to move downward so that it abuts against the lower heater 14. The upper heater 13 and the lower heater 14 heat the ends of the two rubber products to connect them together. After the two rubber products are spliced ​​together, the push rods of the first electric push rod 21 and the second electric push rod 12 retract, driving the upper positioning frame 22 and the upper heater 13 to move upward. The movable upper positioning frame 22 is magnetically attracted by the upper magnetic block 25 and the lower magnetic block 34 to drive the rotating plate 31 to rotate upward. The rotating plate 31 drives the rubber product out of the lower positioning frame 24 and the lower heater 14. Guided by the rotating plate 31, the rubber product slides along the surface of the rotating plate 31 and falls into the interior of the support frame 33. Then the cold air fan 15 cools the rubber product, making it easier for the staff to safely take out the assembled rubber product.
