Abstract
Description
Technical Field
[0001] This utility model relates to the field of silver contact production technology, specifically to an automatic feeding device for a silver contact cold heading machine. Background Technology
[0002] Silver contacts broadly refer to the points where electronic and electrical appliances separate and make contact when they are opened and closed. Because metal conductor terminals are prone to instantaneous heat and sparks at the moment of contact, the contact points are prone to oxidation and electrolysis during high-frequency use. Therefore, the contact points are enlarged and thickened, or made of polymer metals (most commonly copper and silver). Thus, this contact point made of polymer metal, or a point made of the same material but enlarged and thickened, is called a silver contact.
[0003] In the prior art, when the cold heading machine finishes processing, some cold heading machines use the weight of the parts themselves to unload them. When the parts are finished and the unloading is being collected, the uneven unloading speed can easily cause accumulation. When the unloading speed is too fast, the silver contacts may become blocked at the unloading port, making it difficult to collect and use the parts. Utility Model Content
[0004] Therefore, the purpose of this utility model is to provide an automatic feeding device for a silver contact cold heading machine to solve the technical problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic feeding device for a silver contact cold heading machine, comprising a cold heading machine body, a receiving hopper fixedly connected to the lower surface of the cold heading machine body, a connecting pipe fixedly connected to the bottom end of the receiving hopper, a guide plate fixedly connected to one side surface of the top end of the inner wall of the connecting pipe, a first movable plate movably connected to the inner wall of the connecting pipe below the guide plate, a first sprocket fixedly connected to both ends of the first movable plate extending to the outer wall of the connecting pipe, a second movable plate movably disposed below the first movable plate, a second sprocket fixedly connected to one end of the second movable plate extending to the outer wall of the connecting pipe, a first chain sleeved on the outer walls of a set of the first sprockets and the second sprockets, a third movable plate movably disposed between the first movable plate and the second movable plate on the inner wall of the connecting pipe, a first gear fixedly connected to one end of the third movable plate, a second gear meshing with one side of the first gear, a third sprocket fixedly connected to the surface of the second gear away from the third movable plate, and a second chain sleeved on the outer walls of another set of the first sprockets and the third sprockets.
[0006] By adopting the above technical solution, the processed parts can be discharged into the connecting pipe for collection and use through the receiving hopper. The parts can be guided by the guide plate. The first and second sprockets and the first chain work together to drive the first and second movable plates to rotate synchronously, which facilitates the unloading of parts. Another set of first sprockets drives the third sprocket to rotate, which in turn drives the second gear to rotate. The second gear drives the first gear to rotate, which facilitates the simultaneous rotation of the third movable plate, the first movable plate, and the second movable plate, thus facilitating the unloading of parts and preventing parts from accumulating.
[0007] Furthermore, protective covers are fixedly connected to both sides of the connecting pipe. A set of first sprockets and second sprockets are movably connected to the inner wall of a set of protective covers. A motor is fixedly connected to the outer wall of another set of protective covers. The output end of the motor is connected to the second sprocket through a coupling. A set of first sprockets and third sprockets are movably connected to the inner wall of the protective cover.
[0008] By adopting the above technical solution, the protective cover facilitates the protection of the first sprocket, the second sprocket, the third sprocket, etc., and allows the motor to be installed and used.
[0009] Furthermore, a fixed box is fixedly connected to the bottom end of the connecting pipe, and a collection box is movably connected to the inner wall of the fixed box.
[0010] By adopting the above technical solution, the processed parts can be collected and used through the collection box on the fixed box.
[0011] Furthermore, multiple sets of protrusions are fixedly connected to the inner walls on both sides of the connecting pipe, and grooves that contact the protrusions are opened at the center positions of the two sides of the first movable plate, the second movable plate, and the third movable plate.
[0012] By adopting the above technical solution, the protrusions and grooves can be used to vibrate when the first movable plate, the second movable plate, and the third movable plate move, thereby facilitating the unloading of parts and preventing blockage during unloading.
[0013] Furthermore, an angle adjustment assembly is fixedly connected to the upper surface of the first movable plate. The angle adjustment assembly includes two sets of connecting blocks fixedly connected to the upper surface of the first movable plate. A connecting rod is movably connected between the two sets of connecting blocks. A movable rod is movably provided above the connecting rod. A fixing block is fixedly connected to the top of the movable rod. An insert rod is movably connected to the upper surface of the fixing block. A spring is fixedly connected to the outer wall of the insert rod. The end of the spring away from the insert rod is fixedly connected to the fixing block.
[0014] By adopting the above technical solution, the fixed block can be used in conjunction with the movable rod and the connecting rod to drive the first movable plate for adjustment, and the spring can be used to drive the insertion rod for reset.
[0015] Furthermore, a limiting groove is formed on the surface of the movable rod, and the top end of the connecting rod is movably sleeved on the inner wall of the limiting groove.
[0016] By adopting the above technical solution, the connecting rod can be moved by the setting of the limiting groove on the movable rod, so as to facilitate the adjustment of the angle of the first movable plate, the second movable plate and the third movable plate, thereby facilitating the cutting and use of parts of different sizes.
[0017] Furthermore, multiple sets of dovetail grooves are formed on one side surface of the connecting pipe, and a dovetail block is movably sleeved on the inner wall of the dovetail groove. A fixing plate is fixedly connected to one side surface of the dovetail block, and the surface of the fixing plate is provided with a socket that matches the insertion rod.
[0018] By adopting the above technical solution, the fixing plate can be limited by the cooperation between the dovetail block and the dovetail groove.
[0019] In summary, the present invention has the following beneficial effects: the present invention drives the first and second movable plates to rotate simultaneously through the mutual cooperation between the first sprocket, the second sprocket, and the first chain. At the same time, the second gear is driven to rotate through the mutual cooperation between another set of first sprockets, the third sprocket, and the second chain on the first movable plate. The first gear then drives the second movable plate to rotate synchronously. The mutual cooperation between the groove and the protrusion causes the first, second, and third movable plates to vibrate, thereby preventing the parts from getting stuck during material collection and preventing the parts from accumulating, thus facilitating the collection and use of the parts.

Detailed Implementation
[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0027] The embodiments of this utility model will be described below based on its overall structure.
[0028] An automatic feeding device for a silver contact cold heading machine, such as Figure 1-5 As shown, it includes a cold heading machine body 100, and a receiving hopper 110 is fixedly connected to the lower surface of the cold heading machine body 100. The processed parts can be discharged into the connecting pipe 111 for collection and use through the receiving hopper 110.
[0029] For example, a connecting pipe 111 is fixedly connected to the bottom end of the receiving hopper 110, and a guide plate 1111 is fixedly connected to one side surface of the top end of the inner wall of the connecting pipe 111. The parts can be guided by the guide plate 1111.
[0030] For example, a first movable plate 114 is movably connected to the inner wall of the connecting pipe 111 below the guide plate 1111. Both ends of the first movable plate 114 extend to the outer wall of the connecting pipe 111 and are fixedly connected to a first sprocket 1141. A second movable plate 115 is movably provided below the first movable plate 114. One end of the second movable plate 115 extends to the outer wall of the connecting pipe 111 and is fixedly connected to a second sprocket 1151. A first chain 116 is sleeved on the outer wall of a set of first sprockets 1141 and second sprockets 1151. The mutual cooperation of the set of first sprockets 1141, second sprockets 1151 and first chain 116 drives the first movable plate 114 and the second movable plate 115 to rotate synchronously, thereby facilitating the unloading of parts.
[0031] For example, a third movable plate 117 is movably disposed on the inner wall of the connecting pipe 111 between the first movable plate 114 and the second movable plate 115. A first gear 1171 is fixedly connected to one end of the third movable plate 117, and a second gear 1172 meshes with one side of the first gear 1171. A third sprocket 1173 is fixedly connected to the surface of the second gear 1172 away from the third movable plate 117. A second chain 118 is sleeved on the outer wall of another set of first sprockets 1141 and the third sprocket 1173. The third sprocket 1173 is driven to rotate by the other set of first sprockets 1141. The third sprocket 1173 drives the second gear 1172 to rotate, and the second gear 1172 drives the first gear 1171 to rotate. This facilitates the simultaneous rotation of the third movable plate 117, the first movable plate 114, and the second movable plate 115, thereby facilitating the unloading of parts and preventing the accumulation of parts.
[0032] In some examples, please refer to Figure 1 and Figure 2 Protective covers 112 are fixedly connected to both sides of the connecting pipe 111. A set of first sprockets 1141 and second sprockets 1151 are movably connected to the inner wall of a set of protective covers 112. A motor 1152 is fixedly connected to the outer wall of another set of protective covers 112. The output end of the motor 1152 is connected to the second sprocket 1151 through a coupling. Another set of first sprockets 1141 and third sprockets 1173 are movably connected to the inner wall of the protective cover 112. The protective covers 112 facilitate the protection of the first sprockets 1141, second sprockets 1151, and third sprockets 1173. The motor 1152 can be installed and used through the protective covers 112.
[0033] In some examples, please refer to Figure 1 The bottom end of the connecting pipe 111 is fixedly connected to a fixed box 113, and a collection box 1131 is movably connected to the inner wall of the fixed box 113. The processed parts can be collected and used through the collection box 1131 on the fixed box 113.
[0034] In some examples, please refer to Figure 2 and Figure 4 Multiple sets of protrusions 1112 are fixedly connected to the inner walls on both sides of the connecting pipe 111. Grooves 119 that contact the protrusions 1112 are provided at the center of the two sides of the first movable plate 114, the second movable plate 115, and the third movable plate 117. The protrusions 1112 and the grooves 119 can be used to shake when the first movable plate 114, the second movable plate 115, and the third movable plate 117 move, thereby facilitating the unloading of parts and preventing blockage during unloading.
[0035] In some examples, please refer to Figure 2 , Figure 3 , Figure 5An angle adjustment assembly 120 is fixedly connected to the upper surface of the first movable plate 114. The angle adjustment assembly 120 includes two sets of connecting blocks 121 fixedly connected to the upper surface of the first movable plate 114. A connecting rod 122 is movably connected between the two sets of connecting blocks 121. A movable rod 123 is movably provided above the connecting rod 122. A fixing block 124 is fixedly connected to the top of the movable rod 123. The fixing block 124 can cooperate with the movable rod 123 and the connecting rod 122 to drive the first movable plate 114 for adjustment.
[0036] For example, a plug rod 125 is movably connected to the upper surface of the fixing block 124, and a spring 1251 is fixedly connected to the outer wall of the plug rod 125. The end of the spring 1251 away from the plug rod 125 is fixedly connected to the fixing block 124. The spring 1251 can drive the plug rod 125 to be reset.
[0037] In some examples, please refer to Figure 5 A limiting groove 1231 is provided on the surface of the movable rod 123. The top end of the connecting rod 122 is movably sleeved on the inner wall of the limiting groove 1231. The limiting groove 1231 on the movable rod 123 can drive the connecting rod 122 to move, thereby facilitating the adjustment of the angles of the first movable plate 114, the second movable plate 115, and the third movable plate 117, thus facilitating the cutting and use of parts of different sizes.
[0038] In some examples, please refer to Figure 5 The connecting pipe 111 has multiple sets of dovetail grooves on one side surface, and a dovetail block 1261 is movably sleeved on the inner wall of the dovetail groove. A fixing plate 126 is fixedly connected to one side surface of the dovetail block 1261. The fixing plate 126 can be limited by the cooperation between the dovetail block 1261 and the dovetail groove.
[0039] For example, the surface of the fixing plate 126 is provided with a socket that matches the insertion rod 125. By moving the fixing plate 126 below the insertion rod 125 and inserting the insertion rod 125 into the inner wall of the socket, it is convenient to adjust the angles of the first movable plate 114, the second movable plate 115, and the third movable plate 117.
[0040] The working principle of this utility model is as follows: When in use, the parts processed on the cold heading machine body 100 are fed into the receiving hopper 110, and then the parts are fed into the connecting pipe 111 through the receiving hopper 110. The motor 1152 is started, and the motor 1152 can drive the second sprocket 1151 to rotate. The first chain 116 drives the first sprocket 1141 to rotate, so that the first movable plate 114 and the second movable plate 115 can be rotated at the same time.
[0041] Furthermore, when the first movable plate 114 rotates, another set of first sprockets 1141 on the first movable plate 114 rotates. The first sprocket 1141 and the second chain 118 work together to drive the third sprocket 1173 to rotate. The third sprocket 1173 drives the second gear 1172 to rotate, and the second gear 1172 drives the first gear 1171 to rotate. Thus, the first gear 1171 drives the third movable plate 117 to rotate simultaneously with the first movable plate 114 and the second movable plate 115. When the first movable plate 114, the second movable plate 115, and the third movable plate 117 rotate, under the action of the groove 119 and the protrusion 1112, the first movable plate 114, the second movable plate 115, and the third movable plate 117 vibrate, thereby preventing parts from clogging during collection and preventing parts from accumulating during the unloading process, thus facilitating the collection and use of parts.
[0042] Furthermore, when cutting parts of different sizes, the first movable plate 114 is rotated by the fixed block 124 in conjunction with the movable rod 123. By moving the fixed plate 126, the insertion rod 125 is inserted into the inner wall of the insertion hole on the fixed plate 126, which facilitates the adjustment of the angles of the first movable plate 114, the second movable plate 115, and the third movable plate 117, thereby facilitating the cutting and collection of parts of different sizes.
[0043] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
