Description

Technical Field

[0001] The invention relates to the field of silicone rubber sleeve processing, in particular to a silicone rubber insulating protection sleeve processing machine and a processing method. Background Art

[0002] Silicone rubber has excellent electrical, anti-tracking and halogen-free flame retardant properties, and excellent weather resistance. The snap-on protective sleeve is an insulating protection product for electrical lines, usually made of silicone rubber. This sleeve is in sheet form after production and is stacked in rolls. When in use, just press the snap and the slot tightly to complete the covering of the line. Figure 1 As shown, it can be installed without disassembling the wires, and is easy to install.

[0003] When the snap-on protective sleeve is produced, the raw material is first transported to the extruder and then extruded into shape through a die. When the extruded material reaches the required length for production, it is necessary to pause the extrusion of the material, then cut the material with a cutter, and finally roll the produced material into a roll.

[0004] This method of stopping the machine for cutting materials is less frequent for some production orders that require longer materials, and has less impact on production efficiency. However, when producing some orders that require shorter materials, such as processing protective covers for small electrical pipes, the equipment needs to be stopped and cut continuously, which greatly reduces work efficiency.

[0005] Therefore, a silicone rubber insulating protective sleeve processing machine and a processing method are proposed. Summary of the invention

[0006] The purpose of the present invention is to provide a silicone rubber insulating protective sleeve processing machine and a processing method, which solves the problem of low efficiency caused by the need to stop the machine for cutting when producing materials with shorter length requirements in order, and drives the conveying component to operate through the extruded material, and controls the cutting component through the movement of the conveying component to cut the material while moving synchronously with the material.

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A silicone rubber insulating protective sleeve processing machine comprises a base, a mounting frame, an extruder, a molding cavity and a discharge port, wherein a plurality of the mounting frames are arranged on the base, the extruder is arranged on the base through the mounting frame, the molding cavity is connected to the front end of the extruder, and the discharge port is arranged at the front end of the molding cavity. The machine also comprises a guide plate, a conveying assembly, a transmission assembly and a cutting assembly, wherein the guide plate is connected to the molding cavity and is located above the discharge port, the conveying assembly is connected above the base through the mounting frame, the cutting assembly is connected to the mounting frame and is located above the conveying assembly, and the transmission assembly is connected to the conveying assembly and the cutting assembly; the material is extruded from the discharge port and moves along the guide plate to the conveying assembly, and the continuous movement of the material drives the conveying assembly to operate, and the transmission ratio of the conveying assembly to the cutting assembly is adjusted by the transmission assembly, and the conveying assembly drives the cutting assembly to move synchronously with the material and cut the material.

[0009] Because the existing equipment needs to stop the equipment and cut the material according to the order requirements during the extrusion molding process when producing snap-on protective covers, when producing some orders with shorter material lengths, it needs to stop more times, which wastes time and reduces work efficiency. In addition, high-frequency shutdown and startup are also likely to cause damage to the equipment. In the above scheme, the extruded material is pressed against the surface of the conveying component by the guide plate, and sufficient friction is provided by the pressure, so that the movement of the material can drive the conveying component to move synchronously, and drive the cutting component to move along the direction of material movement while moving downward to cut the material, so that the equipment can cut the material without stopping, which greatly improves the work efficiency.

[0010] Preferably, a guide block is connected to the lower left side of the guide plate, and the guide block is in the shape of an arrow, and the arrow is arranged to point downward.

[0011] Through the above scheme, the shape of the guide block is the same as the shape of the snap-on part in the snap-on protective cover, so the guide block can cooperate with the slot in the protective cover. Therefore, when the material is squeezed out from the discharge port, the protective cover will be engaged with the guide block and then transported along the shape of the guide plate, so that it can guide the moving direction of the material.

[0012] Preferably, the distance between the guide plate and the conveying assembly in the vertical direction becomes shorter from back to front, and the shortest distance is equal to the thickness of the material.

[0013] Through the above scheme, by changing the distance between the guide plate and the conveying component, the device can gradually guide the material to the surface of the conveying component through the guide plate, and because the shortest distance between the guide plate and the conveying component is the same as the thickness of the material, a certain pressure can be applied to the material through the guide plate to spread it sufficiently flat on the conveying component, which is convenient for subsequent cutting operations and avoids errors in cutting due to unevenness during material movement. The certain pressure exerted by the guide plate on the material can increase the friction between the material in this area and the conveying component, so that the movement of the conveying component can be more synchronized with the movement of the material, thereby improving the accuracy of the material cutting length.

[0014] Preferably, the conveying assembly includes a conveyor belt, a rotating drum, a sealing plate and a driving gear, the driving gear is connected to the mounting frame, the sealing plate is connected to the driving gear, the rotating drum is connected to the sealing plate, the conveyor belt is sleeved on the outer rings of two rotating drums, and the surface of the conveyor belt is made of a cut-resistant and high-friction material.

[0015] Through the above scheme, the roughness of the conveyor belt surface is increased, thereby increasing the friction between the material and the conveyor belt, making the movement of the conveyor belt and the movement of the material more synchronized, and the sealing plate can prevent the waste generated during the cutting process from falling into the equipment and being inconvenient to clean.

[0016] Preferably, a notch is opened on the left side of the conveyor belt, and the cross-sectional shape of the notch is funnel-shaped.

[0017] Through the above scheme, the shape of the notch can cooperate with the slot part in the snap-on protective cover. On the one hand, the slot part of the snap-on protective cover can be placed in the notch to ensure the flatness of the material surface and facilitate cutting. On the other hand, the contact area between the conveyor belt surface and the material can be increased, thereby increasing the friction and preventing the material from sliding freely on the conveyor belt.

[0018] Preferably, the transmission assembly includes a driven gear, a pulley set 1, a steel belt, a pulley set 2, an adjusting wheel, a compression spring and a connecting rod, the driven gear is connected to a sealing plate and meshes with a driving gear, the pulley set 1 is connected to the driven gear, the pulley set 2 is connected to a mounting frame and its height is located above the conveyor belt, the steel belt is connected between the pulley set 1 and the pulley set 2, the adjusting wheel is connected to the pulley set 1, the two ends of the compression spring are respectively connected to the pulley set 2 and the mounting frame, the connecting rod is connected to the pulley set 2, and the extension line of the connecting rod in the length direction intersects with the center of the circle of the pulley set 2.

[0019] Through the above scheme, pulley block 1, pulley block 2 and the steel belt can be combined into a structure similar to a continuously variable transmission, so that the device can easily adjust the transmission ratio, and then conveniently control the cutting speed of the cutting component.

[0020] Preferably, a sliding groove is provided in the middle of the sealing plate, and a toothed plate 1 is slidably arranged in the sliding groove, and the toothed plate 1 passes through a cutting assembly, and the cutting assembly comprises a mounting rod, a transmission gear, a toothed plate 2, a rack, a limiting rod, a reset spring, a guard plate and a blade, the mounting rod is connected to the connecting rod, the transmission gear is arranged inside the mounting rod, the toothed plate 2 is connected inside the mounting rod, the toothed plate 1 and the toothed plate 2 are both meshed with the transmission gear, and the teeth of the toothed plate 1 and the toothed plate 2 are in the same direction, the limiting rod is connected to the upper and lower ends of the toothed plate 2, the rack is connected to the limiting rod, and the teeth of the rack are in the same direction as those of the toothed plate 2, the reset spring is sleeved on the limiting rod and its two ends are respectively connected to the toothed plate 2 and the rack, the blade is connected to the mounting rod, and the guard plate is connected to the mounting rod and is arranged on the front and rear sides of the blade.

[0021] Through the above scheme, when the mounting rod is in an ascending state, the guard plate will move downward to cover the blade, which can protect the blade and avoid harm to workers. When the material needs to be cut, the mounting rod will drop, and the guard plate will move upward to expose the blade so that it can cut the material normally. The height of the guard plate is set so that when the blade cuts the material, the guard plate will press the front and rear sides of the cutting position to prevent the material from moving during the cutting process, resulting in inaccurate material cutting.

[0022] Preferably, an arc-shaped cutter is provided at the bottom left side of the blade, and the cross-sectional shape of the arc-shaped cutter is the same as the cross-sectional shape of the notch.

[0023] Through the above solution, the arc-shaped cutter can cooperate with the notch. When the cutter cuts the material, the arc-shaped cutter will extend into the notch to cut the material in the notch.

[0024] Preferably, a pressing block is provided at the bottom left side of the guard plate, and the shape of the pressing block is the same as that of the guide block.

[0025] Through the above scheme, during cutting, the pressing block will be pressed into the material in the slot. Since the material in the slot is the slot area of ​​the snap-on protective cover, it can match the shape of the pressing block to increase the contact area, thereby pressing the material near the cutting position to be stable and flat, making cutting easier.

[0026] A method for processing a silicone rubber insulating protective sleeve comprises the following steps:

[0027] S1: First, start the extruder and adjust the transmission component to a suitable transmission ratio, then feed the raw material into the extruder, and then the extruder extrude the raw material and shape the material under the action of the molding cavity;

[0028] S2: Then, the extruded material moves along the guide plate that matches its shape to the surface of the conveyor belt. Under the action of friction, the conveyor belt moves with the movement of the material.

[0029] S3: When the material is conveyed to a certain length, the conveying assembly drives the cutting assembly through the transmission assembly, so that the cutter moves synchronously along the moving direction of the material and cuts the material on the conveyor belt.

[0030] Compared with the prior art, the present invention has the following beneficial effects:

[0031] 1. Compared with the existing processing equipment of silicone rubber insulating protective sleeves, the present invention can make use of the power when the material is extruded to increase the friction so that the moving material can drive the conveying component to operate, and convey the material out through the conveyor belt to avoid the accumulation of material at the discharge port. On the other hand, the conveyor belt that moves with the movement of the material can drive the cutting component to move along the moving direction of the material while moving downward to cut the material, so that the equipment can cut the material without stopping, which greatly improves the work efficiency.

[0032] 2. By setting a guide plate and a guide block, the guide block can be matched with the card slot in the snap-on protective cover to limit the extruded material and guide it to move along the guide plate. Since the distance between the guide plate and the conveyor belt is gradually shortened, the extruded material is guided onto the conveyor belt. The shape of the guide block can cooperate with the notch on the conveyor belt, so that the material limited by the guide plate can fit the surface of the conveyor belt better when moving onto the conveyor belt, thereby increasing the friction in this area and ensuring that the conveyor belt can move synchronously according to the moving speed of the material.

[0033] 3. By setting guard plates and blades, the guard plates are distributed on both sides of the blade. When there is no need to cut the material, the guard plates will cover the blade, thereby protecting the blade and extending the service life of the blade. On the other hand, it can also prevent the blade from causing harm to workers and improve production safety. When cutting the material, the guard plate rises to a certain height and exposes the blade so that it can cut the material normally. During the cutting process, the guard plates on both sides of the blade will press on the surface of the material, making the cutting position smoother and more stable, thereby ensuring the cutting accuracy and cutting quality.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] See also Figures 1 to 9 The present invention provides a silicone rubber insulating protective sleeve processing machine and processing method, and the technical solution is as follows:

[0046] For details, please refer to Figures 1 to 3A silicone rubber insulating protective sleeve processing machine is used in conjunction with a snap-on protective sleeve. After the snap-on protective sleeve is produced, the whole is in sheet shape, and buckles and slots that can cooperate with each other are provided at both ends. It includes a base 1, a mounting frame 2, an extruder 3, a molding cavity 4 and a discharge port 5. A plurality of the mounting frames 2 are arranged on the base 1, and the extruder 3 is arranged on the base 1 through the mounting frame 2. The molding cavity 4 is connected to the front end of the extruder 3. A mold for extruding a material is arranged in the molding cavity 4 to determine the shape of the extruded material. The discharge port 5 is arranged at the front end of the molding cavity 4, and also includes A guide plate 6, a conveying assembly 7, a transmission assembly 8 and a cutting assembly 9, wherein the guide plate 6 is connected to the forming cavity 4 and is located above the discharge port 5, and the distance between the guide plate 6 and the conveying assembly 7 in the vertical direction becomes shorter from the back to the front, so that the device can gradually guide the material to the surface of the conveying assembly 7 through the guide plate 6, and the shortest distance between the guide plate 6 and the conveying assembly 7 is equal to the thickness of the material. When the material is guided to the surface of the conveying assembly 7, a certain force will be applied due to the distance between the guide plate 6 and the conveying assembly 7, thereby making the material lay more evenly on the conveying assembly 7;

[0047] A guide block 601 is connected to the lower left side of the guide plate 6. Since the shape of the buckle is generally arrow-shaped, the guide block 601 is arrow-shaped, and the arrow is set to point downward. At this time, the position of the guide block 601 is the position of the card slot for extruding the material, so the extruded material can cooperate with the guide block 601. When the material is extruded from the discharge port 5, the protective cover will be sleeved with the guide block 601, and then conveyed along the shape of the guide plate 6, so that it can guide the moving direction of the material, and can also increase the friction between the material in this area and the conveying component 7 by increasing the contact area, so that the movement of the conveying component 7 can be more synchronized with the movement of the material. The shape of the guide plate 6 from the molding cavity 4 to the conveyor belt 701 is a smooth curved surface, so that the movement of the material is smoother;

[0048] The conveying assembly 7 is connected to the top of the base 1 through the mounting frame 2, the cutting assembly 9 is connected to the mounting frame 2 and is located above the conveying assembly 7, and the transmission assembly 8 is connected to the conveying assembly 7 and the cutting assembly 9; since high-frequency shutdown and startup are likely to cause damage to the equipment, this solution extrude the material from the discharge port 5 and move it along the guide plate 6 to the conveying assembly 7, and the continuous movement of the material drives the conveying assembly 7 to operate, and the transmission ratio of the conveying assembly 7 to the cutting assembly 9 is adjusted by the power assembly, and the conveying assembly 7 drives the cutting assembly 9 to cut the moving material, so that the cutting assembly 9 can move along the moving direction of the material while moving downward to cut the material, so that the equipment can cut the material without stopping, which greatly improves the work efficiency.

[0049] like Figure 4As shown, the conveying assembly 7 includes a conveyor belt 701, a rotating drum 702, a sealing plate 703 and a driving gear 704. The surface of the conveyor belt 701 is a cutting-resistant and high-friction material, so that it can be used as a workbench when the cutting assembly 9 is cutting. In addition, the high roughness of the conveyor belt 701 can increase the friction between the material and the conveyor belt 701, so that the movement of the conveyor belt 701 and the movement of the material are more synchronized. The driving gear 704 is connected to the mounting frame 2, and the sealing plate 703 is connected to the driving gear 704. The shape of the sealing plate 703 is similar to the cross-sectional shape of the conveyor belt 701, both of which are long waist hole shapes, and the sealing plate 703 can prevent waste materials generated during the cutting process from falling into the equipment and being inconvenient to clean. The rotating drum 702 is connected to the sealing plate 703. The conveyor belt 701 is sleeved on the outer rings of the two rotating drums 702. A slot 705 is opened on the left side of the conveyor belt 701. The cross-sectional shape of the slot 705 is funnel-shaped, which is similar to the shape of the card slot in the snap-on protective cover. Therefore, the card slot can be accommodated in the slot 705, avoiding that the material has a part that is too protruding on the conveyor belt 701, ensuring the flatness of the material surface, facilitating cutting, and increasing the friction by increasing the contact area to avoid sliding and deflection of the material during cutting.

[0050] like Figure 5 As shown, the transmission assembly 8 includes a driven gear 801, a pulley block 802, a steel belt 803, a pulley block 804, an adjusting wheel 805, a compression spring 806 and a connecting rod 807. The driven gear 801 is connected to the sealing plate 703 and meshes with the driving gear 704, and the driven gear 801 has the same number of teeth as the driving gear 704. The pulley block 802 is connected to the driven gear 801. The pulley block 802 includes a fixed pulley and a movable pulley. The adjusting wheel 805 is connected to the pulley block 802. The position of the fixed pulley is fixed, and the adjusting wheel 805 can change the spacing with the fixed pulley by adjusting the position of the movable pulley. The pulley block 804 is connected to the mounting frame 2 and its height is located above the conveyor belt 701. The composition of the pulley block 804 is the same as that of the pulley block. The movable pulley in the pulley block 804 is the same as the first pulley 802, but the movable pulley in the pulley block 804 is passively adjusted by the compression spring 806, and the steel belt 803 is the connection and adjustment hub between the pulley block 1 802 and the pulley block 2 804. The steel belt 803 is connected between the pulley block 1 802 and the pulley block 2 804. The two ends of the compression spring 806 are respectively connected to the pulley block 2 804 and the mounting frame 2. The connecting rod 807 is connected to the pulley block 804 to form a structure similar to a continuously variable transmission, so that the device can easily adjust the transmission ratio, and then conveniently control the cutting speed of the cutting component 9. The extension line of the length direction of the connecting rod 807 intersects with the center of the pulley block 2 804, and the connecting rod 807 is fixedly connected to the pulley block 2 804 and is connected at a position far away from the center of the circle.

[0051] like Figure 6 and Figure 7 As shown, a slide groove 10 is provided in the middle of the sealing plate 703, and the length of the slide groove 10 is greater than the length of the rotation track of the connecting rod 807 in the horizontal position. A tooth plate 11 is slidably arranged in the slide groove 10, and the tooth plate 11 passes through the cutting assembly 9. The cutting assembly 9 includes a mounting rod 901, a transmission gear 902, a tooth plate 2 903, a rack 904, a limit rod 905, a reset spring 906, a guard plate 907 and a blade 908. The mounting rod 901 is connected to the connecting rod 807, and the mounting rod 901 can follow the track of one end of the connecting rod 807 to perform a circular rotation. The tooth plate 11 arranged in the slide groove 10 can prevent the mounting rod 901 from rotating, thereby ensuring that the mounting rod 901 is in a vertical state.

[0052] The toothed plate 903 is connected to the inside of the mounting rod 901, and the transmission gear 902 is arranged inside the mounting rod 901. The length of the transmission gear 902 is greater than the sum of the lengths of the toothed plate 11 and the toothed plate 2 903 in the horizontal direction. The toothed plate 1 11 and the toothed plate 2 903 are both meshed with the transmission gear 902, and the teeth of the toothed plate 1 11 and the toothed plate 2 903 are oriented in the same direction. The toothed plate 1 11 and the toothed plate 2 903 are both arranged on one side of the transmission gear 902 close to the middle of the conveyor belt 701. The limit rod 9 05 is connected to the upper and lower ends of the second tooth plate 903, the rack 904 is connected to the limiting rod 905, and the teeth of the rack 904 are oriented in the same direction as the second tooth plate 903, the reset spring 906 is sleeved on the limiting rod 905 and the two ends are respectively connected to the second tooth plate 903 and the rack 904, when the transmission gear 902 drives the second tooth plate 903 to move downward, after moving to a certain extent, the transmission gear 902 will mesh with the rack 904, and under the action of the reset spring 906, the second tooth plate 903 maintains the existing height;

[0053] The blade 908 is connected to the mounting rod 901. A curved cutter 9081 is provided at the bottom left side of the blade 908. The cross-sectional shape of the curved cutter 9081 is the same as the cross-sectional shape of the notch 705. The same shape enables it to match the notch 705. When the cutter cuts the material, the curved cutter 9081 will extend into the notch 705 to cut the material in the notch 705.

[0054] The guard plate 907 is connected to the mounting rod 901 and is arranged on the front and rear sides of the blade 908. When the mounting rod 901 is in an ascending state, the guard plate 907 will move downward to block the blade 908. When the mounting rod 901 is lowered, the guard plate 907 will move upward to expose the blade 908 so that it can cut the material normally. The height setting of the guard plate 907 enables the blade 908 to cut the material while the guard plate 907 presses the front and rear sides of the cutting position to prevent the material from moving during the cutting process, resulting in inaccurate material cutting. A pressing block 9071 is provided at the bottom left side of the guard plate 907. The shape of the pressing block 9071 is the same as that of the guide block 601. When cutting, since the material in the notch 705 is the card slot area of ​​the snap-on protective cover, it can cooperate with the shape of the pressing block 9071 to increase the contact area, thereby pressing the material near the to-be-cut position to be stable and flat, which is convenient for cutting.

[0055] The specific working principle is: the movement of the material drives the conveyor belt 701 to move, and according to the moving distance of the conveyor belt 701, the blade 908 is controlled to move forward at the same horizontal moving speed as the material, and at the same time move downward to cut the material without stopping.

[0056] Specifically, the raw material is first fed into the extruder 3, and the material is extruded from the molding cavity 4 by extrusion. When the molded material is extruded from the discharge port 5, it will first contact the guide plate 6; wherein, the material extruded from the discharge port 5 is a snap-on protective cover, and the slot portion is located on the left side of the discharge port 5. The shape of the slot is similar to a semi-ellipse. Two protrusions are provided on both sides of the opening of the slot. These two protrusions have a tendency to close the slot, and thus the arrow-shaped buckle can be clamped to prevent it from easily detaching. The guide block 601 on the left side below the guide plate 6 is a shape that can cooperate with the slot, that is, an arrow shape similar to the buckle shape, wherein the arrow-shaped head is a triangle, with its tip facing outward and its straight face facing inward. When the tip leads the arrow as a whole into the slot, its rear end will be difficult to detach from the slot on its own due to its length. , thereby achieving the fixation of the buckle and the slot, and this is also the reason why the guide block 601 can cooperate with the slot. In this solution, the connection between the guide plate 6 and the molding cavity 4 is immediately above the discharge port 5, and the guide block 601 is also located in the area where the discharge port 5 is extruded and the slot is directly sleeved on the guide block 601. It is like placing a rod at the ring-shaped extrusion port when producing a ring. At this time, the extruded ring will be directly sleeved on the rod and move forward along the rod under the push of the subsequent extruded material. Therefore, the guide block 601 can cooperate with the slot part of the buckle protective cover. When the material is extruded from the discharge port 5, the protective cover will be clamped with the guide block 601, and then move along the guide plate 6 to guide the material toward the direction of the conveyor belt 701.

[0057] Since the distance between the guide plate 6 and the conveyor belt 701 in the vertical direction becomes shorter from the back to the front, and the shortest distance is equal to the thickness of the material, and the influence of the high roughness of the surface of the conveyor belt 701, when the material contacts the conveyor belt 701 along the guide plate 6, sufficient friction will be generated between the material and the conveyor belt 701, so that the movement of the material can drive the conveyor belt 701 to move, and the length of the material can be judged according to the number of rotations of the conveyor belt 701;

[0058] When the material reaches the required length, it needs to be cut. At this time, the movement of the conveyor belt 701 will be transmitted through the transmission component 8, and finally the cutting component 9 will be driven by the connecting rod 807 to make a circular motion around the center of the pulley group 2 804. During the circular motion, the cutting component 9 slides up and down along the tooth plate 11, and moves back and forth relative to the sealing plate 703 through the tooth plate 11; when cutting, the cutting component 9 moves forward and downward synchronously with the material, so as to cut the material without stopping the machine. Specifically, when the mounting rod 901 moves downward along the tooth plate 11, the transmission gear 902 moves downward and rotates relative to the tooth plate 11, and drives the tooth plate 2 903 meshing with the transmission gear 902 to move upward. When the tooth plate 2 903 moves upward to the specified position, the tooth plate 11 is rotated. After the tooth plate 903 moves to the position, it separates from the transmission gear 902. At this time, the rack 904 is meshed with the transmission gear 902, and the rack 904 makes the tooth plate 903 stay in this position. Since the tooth plate 903 is connected with the guard plate 907, the tooth plate 903 will drive the guard plate 907 to move upward when it rises, thereby exposing the blade 908, so that it can cut the material normally, wherein the blade 908 is set at the bottom of the mounting rod 901. When the mounting rod 901 moves to the bottom, the blade 908 contacts the material and cuts the material. Due to the trajectory of its circular motion, the blade 908 moves forward synchronously with the material while pressing down to cut the material. Therefore, the material can be cut without stopping. Finally, the cut material is sent out of the equipment along the conveyor belt 701.

[0059] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
