Description

Technical Field

[0001] The present application relates to the field of molding machines, and in particular to a molding machine for elastic belt molding. Background Art

[0002] An elastic belt can achieve stable tension. During the production process, a molding machine is required. The molding machine is used to attach a backing cloth or a backing adhesive layer to a mold, and by rotating the mold, multiple layers are pasted with adhesive to form the belt.

[0003] The utility model patent with the publication number of CN214688061U discloses a molding machine for elastic belt molding, which relates to the technical field of molding machines, including a frame and a mold for winding backing adhesive. The mold is in a cylindrical shape, the mold is horizontally arranged and rotatably installed on the frame. The frame is slidably installed with a mounting rod along the radial direction of the mold. The mounting rod is arranged parallel to the mold. A cutting mechanism is installed on the mounting rod. The cutting mechanism is slidably arranged along the axial direction of the mold. The frame is equipped with a first driving member, and the first driving member drives the cutting mechanism to cut the backing adhesive along the axial direction of the mold.

[0004] Generally, the belt will be wound around the mold in multiple layers. When the molding machine cuts or punches the belt, it is difficult to control the force of the tool, and it is easy to damage the inner layer of the belt during cutting or punching. Utility Model Content

[0005] In order to reduce the damage to the inner layer of the belt when the molding machine cuts or punches the belt, the present application provides a molding machine for elastic belt molding.

[0006] The molding machine for elastic belt molding provided by the present application adopts the following technical solutions:

[0007] A molding machine for elastic belt molding includes a frame and a mold rotatably connected to the frame. A horizontal mounting rod is provided on the frame. A sliding base is slidably connected to the mounting rod in the horizontal direction. A driving member for driving the sliding base to move is provided on the frame. A cutting mechanism and a punching mechanism are provided on the sliding base. A vertical baffle parallel to the mounting rod is provided on the frame. The baffle is located between the mounting rod and the mold, and the belt passes through between the mounting rod and the baffle first and then winds around the mold during transportation.

[0008] By adopting the above technical solution, when the belt is being conveyed, it first passes through between the baffle and the mounting rod from the lower end of the baffle, and then winds around the mold after passing through the upper end of the baffle. When the cutting mechanism or the punching mechanism cuts or punches the belt, the baffle plays a protective role, so that only the layer of the belt between the baffle and the mounting rod will be cut or punched, reducing the damage to the inner layer of the belt when the forming machine cuts or punches the belt.

[0009] Optionally, guide rollers are rotatably connected to both the upper and lower ends of the baffle, and both of the guide rollers are arranged parallel to the mounting rod.

[0010] By adopting the above technical solution, the two guide rollers play a role in reducing the friction between the belt and the baffle, reducing the wear of the belt and the baffle.

[0011] Optionally, the cutting mechanism includes a first cylinder and a cutter. The first cylinder is arranged on the sliding base and faces the baffle, the cutter is connected to the piston rod of the first cylinder, and the cutting edge of the cutter faces the baffle.

[0012] By adopting the above technical solution, the cutter is driven to move by the first cylinder to realize the cutting of the belt by the cutter, and the operation is relatively convenient.

[0013] Optionally, a vertical mounting plate perpendicular to the cutter is provided at the end of the cutter away from the baffle. A connecting block is provided on the piston rod of the first cylinder, a T-shaped groove is opened at the upper end of the connecting block, and the end of the cutter and the mounting plate are inserted into the T-shaped groove in the vertical direction.

[0014] By adopting the above technical solution, the cutter and the mounting plate are inserted into the T-shaped groove in the vertical direction to complete the installation, and this installation method is relatively convenient for disassembly and assembly.

[0015] Optionally, the driving member includes a driving motor and a screw rod. A horizontal sliding groove is opened on the mounting rod, the screw rod is rotatably connected in the sliding groove along the length direction of the sliding groove, the sliding base is sleeved on the screw rod and is in threaded cooperation with the screw rod, and the transmission shaft of the driving motor is coaxially arranged with the screw rod.

[0016] By adopting the above technical solution, the driving motor drives the screw rod to rotate. When the screw rod rotates, it is in threaded cooperation with the sliding base, thereby driving the sliding base to move along the length direction of the sliding groove.

[0017] Optionally, the punching mechanism includes a second cylinder and a pointed rod. The second cylinder is arranged on the sliding base and faces the baffle, the pointed rod is coaxially arranged with the piston rod of the second cylinder, and the tip of the pointed rod faces the baffle.

[0018] By adopting the above technical solution, the second cylinder drives the pointed rod to move, so that the pointed rod can punch the belt.

[0019] Optionally, a buffer tube is coaxially arranged on the piston rod of the second cylinder. The pointed rod is slidably connected to the buffer tube along the axial direction of the buffer tube. A spring is arranged in the buffer tube. One end of the spring is connected to the pointed rod, and the other end of the spring is connected to the piston rod of the second cylinder.

[0020] By adopting the above technical solution, when the second cylinder drives the pointed rod to punch the belt, the spring plays a buffering role for the pointed rod, reducing the occurrence of damage to the pointed rod caused by too much force of the second cylinder.

[0021] Optionally, the pointed rod includes a pointed part and a connecting rod. The connecting rod is connected to the spring, and the pointed part and the connecting rod are threadedly connected.

[0022] By adopting the above technical solution, when the pointed rod needs to be replaced, the pointed part is unscrewed from the connecting rod, and then a new pointed part is threadedly connected to the connecting rod to complete the replacement, and the operation is relatively convenient.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. When the cutting mechanism or the punching mechanism cuts or punches the belt, the baffle plays a protective role, so that only the layer of the belt between the baffle and the mounting rod will be cut or punched, reducing the damage to the inner layer of the belt when the forming machine cuts or punches the belt;

[0025] 2. The two guide rollers play a role in reducing the friction between the belt and the baffle, reducing the wear of the belt and the baffle. Description of the Drawings

[0033] An embodiment of the present application discloses a forming machine for elastic belt forming. Referring to Figure 1 and Figure 2 , a forming machine for elastic belt forming includes a frame 1 and a die 11 rotatably connected to the frame 1. The die 11 is cylindrical. A horizontal mounting rod 2 and a vertical baffle 7 are fixedly connected to the frame 1. The die 11, the baffle 7, and the mounting rod 2 are all arranged parallel to each other and are arranged in sequence along the belt conveying direction. Guide rollers 71 are rotatably connected to both the upper and lower ends of the baffle 7. Both guide rollers 71 are arranged parallel to the mounting rod 2. When the belt is conveyed, it first enters between the baffle 7 and the mounting rod 2 from below the baffle 7, and then winds around the die 11 through the upper end of the baffle 7. The guide rollers 71 play a role in reducing the friction between the belt and the baffle 7.

[0034] Referring to Figure 2 and Figure 3 , a sliding groove 43 is provided on the surface of the mounting rod 2 facing the baffle 7 and is arranged along the length direction of the mounting rod 2. A sliding base 3 is slidably connected in the sliding groove 43 along the length direction of the sliding groove 43. A driving member 4 for driving the sliding base 3 to move is installed on the frame 1. The driving member 4 includes a driving motor 41 and a screw rod 42. The screw rod 42 is rotatably connected in the sliding groove 43 and is arranged along the length direction of the sliding groove 43. The sliding base 3 is sleeved on the screw rod 42 and is in threaded cooperation with the screw rod 42. The transmission shaft of the driving motor 41 is coaxially connected to the screw rod 42 to drive the screw rod 42 to rotate. When the screw rod 42 rotates, it drives the sliding base 3 to move.

[0035] Referring to Figure 2 , Figure 3 and Figure 4, a cutting mechanism 5 for cutting the belt and an opening mechanism for punching holes in the belt are installed on one side of the sliding base 3 facing the baffle 7. The cutting mechanism 5 includes a first cylinder 51 and a cutting tool 52. The first cylinder 51 is installed on the sliding base 3 and faces the baffle 7. A connecting block 53 is connected to the piston rod of the first cylinder 51. A T-shaped groove is opened at the upper end of the connecting block 53. A mounting plate 55 which is vertical and perpendicular to the cutting tool 52 is connected to the handle of the cutting tool 52. Both the mounting plate 55 and the handle part of the cutting tool 52 are inserted into the T-shaped groove in the vertical direction, thus completing the installation of the cutting tool 52.

[0036] Referring to Figure 2 , Figure 3 and Figure 5 , the punching mechanism 6 includes a second cylinder 61 and a pointed rod 62. The pointed rod 62 includes a pointed part 621 and a connecting rod 622. The pointed part 621 is threadedly connected to the connecting rod 622, thus facilitating the replacement of the pointed part 621. The second cylinder 61 is installed on the sliding base 3 and faces the baffle 7. A buffer tube 64 is coaxially connected to the piston rod of the second cylinder 61. A spring 63 is installed in the buffer tube 64. One end of the spring 63 is connected to the piston rod of the second cylinder 61, and the other end of the spring 63 is connected to the connecting rod 622. The pointed rod 62 is coaxially and slidably connected in the buffer tube 64.

[0037] The implementation principle of an embodiment of a forming machine for elastic belt forming in this application is as follows: When the belt is being conveyed, it first passes through between the baffle 7 and the mounting rod 2 from the lower end of the baffle 7, and then winds around the mold 11 through the upper end of the baffle 7. When the cutting mechanism 5 or the punching mechanism 6 cuts or punches the belt, the baffle 7 plays a protective role, so that only the layer of the belt between the baffle 7 and the mounting rod 2 will be cut or punched, reducing the damage to the inner layer of the belt when the forming machine cuts or punches the belt.

[0038] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
