Description

Technical Field

[0001] This utility model relates to the technical field of silicone processing equipment, specifically to an automatic feeding and dispensing device. Background Technology

[0002] A vulcanizing machine, also known as a desulfurization machine, is a piece of equipment used to enhance the vulcanization reaction of rubber products. Its main function is to add a vulcanizing agent to the mixed rubber raw materials and react them under high temperature and high pressure, causing the rubber to undergo vulcanization cross-linking, thereby giving the rubber better strength, hardness, wear resistance, cold resistance, and chemical corrosion resistance.

[0003] In the existing silicone processing, the raw materials are usually first stirred, extruded and tumbled in an open mill to make them evenly mixed. The mixed raw materials are then transported manually and pre-treated. Finally, the treated materials are put into a vulcanizing machine for vulcanization. This process is not only inefficient, but also cannot guarantee the quality of the products. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes an automatic feeding and dispensing device.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0007] The molding die includes a discharge plate and a discharge nozzle arranged sequentially along the discharge direction. The discharge plate is connected to the output end of the feeding pipe. The discharge nozzle forms a glue inlet channel connected to the discharge plate. The discharge plate has a plurality of circular strip extrusion holes. The discharge end of the discharge nozzle forms a plurality of rectangular discharge grooves.

[0008] Preferably, the discharge nozzle is provided with a cutting component, which includes a cutter movably disposed above the discharge trough and a lifting unit that drives the cutter to move up and down. Through the above improvements, the silicone extruded from the discharge trough is cut into silicone sheets of the same size.

[0009] Preferably, an adjusting plate is inserted at the bottom of the discharge nozzle. The adjusting plate moves up and down along the discharge trough to adjust the diameter of the discharge trough. Through the above improvements, the diameter of the discharge trough can be controlled by the adjusting plate to meet the production needs of different sizes and models.

[0010] Preferably, an adjusting screw is inserted at the bottom of the discharge nozzle. The adjusting screw is connected to an adjusting plate. When the adjusting screw is rotated, the adjusting plate moves up and down. With the above improvement, when it is necessary to adjust the size of the discharge trough, the adjusting screw can be rotated to make the adjusting plate move up and down, thereby realizing the rapid adjustment of the discharge trough diameter.

[0011] Preferably, the output end of the feeding tube is connected to a discharge seat, the discharge seat has an insertion groove, the discharge plate is inserted into the insertion groove, and the discharge seat is connected to a mounting bracket, the mounting bracket is rotatably provided with a mounting screw, the mounting screw is connected to the discharge plate, and the mounting screw rotates to allow the discharge plate to insert into or detach from the insertion groove. With the above improvement, the discharge plate can be inserted into or detached from the insertion groove by rotating the mounting screw, which is more convenient for daily cleaning and avoids the glue clogging the strip extrusion hole.

[0012] Preferably, the discharge plate has several mounting steps, and the mounting steps are embedded with aperture control plates. The strip extrusion holes are formed on the aperture control plates. Through the above improvements, aperture control plates with different apertures can be replaced to cooperate with different mounting steps. Different aperture control plates have different extrusion speeds and different characteristics.

[0013] Preferably, the discharge plate has an installation groove, a limiting post is provided in the installation groove, and a limiting hole is formed on the discharge seat for the limiting post to be inserted. An elastic element is provided in the installation groove, one end of the elastic element abuts against the installation groove and the other end abuts against the limiting post, so that the limiting post always has a tendency to extend out of the installation groove. With the above improvements, when the discharge plate is inserted, after it is inserted to the designated position, the limiting post will be inserted into the limiting hole to ensure the accuracy and stability of the discharge plate installation.

[0014] Preferably, the frame is provided with a feeding assembly, which includes an adsorption plate, a lifting module for driving the adsorption plate to move up and down, a telescopic module for driving the adsorption plate to move back and forth, and a horizontal moving module for driving the adsorption plate to move horizontally. The adsorption plate is provided with several adsorption units. Through the above improvements, the horizontal moving module and the lifting module are used to drive the adsorption plate to move up, down, left and right, and the adsorption units on the adsorption plate adsorb the vulcanized product, thereby realizing automatic feeding.

[0015] Preferably, the rubber cylinder is provided with a pressure rod and a pressing unit that drives the pressure rod to move. The pressing unit drives the pressure rod to descend and forces the rubber material in the rubber cylinder to be injected into the feeding pipe.

[0016] Preferably, a movable lead screw is mounted on the frame, and a sliding block is provided on the movable lead screw. The sliding block is connected to the mounting platform. The movable lead screw rotates and drives the sliding block to move, thereby driving the mounting platform to move. Through the above improvements, the movable lead screw can be used to drive the sliding block to move, thereby adjusting the position of the discharge end of the molding die, so that the extruded silicone sheet can fall directly into the vulcanizing machine to achieve automatic feeding.

[0017] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0018] The rubber compound is received from the open mill via a rubber cylinder. The rubber cylinder feeds the compound into the feeding pipe, and the conveying screw transports the compound to the molding die. First, the compound passes through the discharge plate and then through the strip extrusion hole, becoming a strip shape to eliminate air bubbles. It then flows into the inlet channel and finally exits through the discharge chute, becoming a sheet shape before entering the vulcanizing machine. The entire process requires no manual feeding, achieving automatic feeding of the vulcanizing machine. This not only effectively improves product quality but also increases production efficiency.

[0031] 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.

[0032] It should be understood that although the terms upper, middle, lower, top, one end, etc., appear in this document to describe various elements, these elements are not limited by these terms. These terms are only used to distinguish the elements from each other for ease of understanding, and are not used to define any directional or sequential restrictions.

[0033] Example 1

[0034] like Figure 1-7 As shown, an automatic feeding and dispensing device includes a frame 1, an installation platform 2 slidably mounted on the frame 1, a feeding pipe 3 mounted on the installation platform, a conveying screw 4 conveying material inside the feeding pipe 3, a molding die 5 connected to the output end of the feeding pipe 3, and a glue cylinder 6 for providing glue material connected to the feeding pipe 3.

[0035] Specifically, the molding die 5 includes a discharge plate 1.1 and a discharge nozzle 1.2 arranged sequentially along the discharge direction. The discharge plate 1.1 is connected to the output end of the feeding pipe 3. The discharge nozzle 1.2 forms a glue inlet channel connected to the discharge plate 1.1. The discharge plate 1.1 has several circular strip extrusion holes 1.4. The discharge end of the discharge nozzle 1.2 forms several rectangular discharge grooves 1.5.

[0036] In the entire feeding process, the open mill first feeds the processed rubber material into the rubber cylinder 6, which receives the rubber material from the open mill. The rubber cylinder 6 then feeds the rubber material into the feeding pipe 3, and the conveying screw 4 transports the rubber material to the molding die 5. First, the rubber material passes through the discharge plate 1.1, then through the strip extrusion hole 1.4, and is extruded into a strip shape, thereby eliminating air bubbles in the rubber material. Then, it flows into the rubber inlet channel and finally exits through the discharge chute 1.5, becoming a sheet shape and entering the vulcanizing machine. The entire process does not require manual feeding, realizing automatic feeding of the vulcanizing machine, which can not only effectively improve product quality but also increase production efficiency.

[0037] In addition, a cutting assembly 2.1 is provided on the discharge nozzle 1.2. The cutting assembly 2.1 includes a cutter 2.2 movably disposed above the discharge trough 1.5, and a lifting unit 2.3 that drives the cutter 2.2 to move up and down. When silicone is extruded from the discharge trough 1.5, the lifting unit 2.3 will drive the cutter downward to cut the extruded silicone into silicone sheets of specified specifications and seal the discharge trough 1.5 so that the silicone sheets of specified specifications can enter the vulcanizing machine to ensure the quality of the product.

[0038] As a further explanation of the embodiment of the discharge plate 1.1, the output end of the feeding pipe 3 is connected to the discharge seat 4.1, the discharge seat 4.1 is formed with an insertion groove 4.2, the discharge plate 1.1 is inserted into the insertion groove 4.2, and the discharge seat 4.1 is connected to the mounting bracket 4.3, the mounting bracket 4.3 is rotatably provided with a mounting screw 4.4, the mounting screw 4.4 is connected to the discharge plate 1.1, and the mounting screw 4.4 rotates to make the discharge plate 1.1 insert into or disengage from the insertion groove 4.2.

[0039] During the production process, the discharge plate 1.1 can be inserted into or removed from the insertion slot 4.2 by rotating the installation screw 4.4, which makes daily cleaning easier and avoids the glue clogging the strip extrusion hole 1.4.

[0040] Regarding a further explanation of the embodiment of the glue cylinder 6, the glue cylinder 6 is provided with a pressure rod 7.1 and a pressing unit 7.2 for driving the pressure rod 7.1 to move.

[0041] The rubber compound from the open mill can be injected into the rubber cylinder 6. The pressing unit 7.2 drives the pressure rod 7.1 to descend, forcing the rubber compound in the rubber cylinder 6 into the feeding pipe 3, thereby achieving automatic feeding and improving production efficiency.

[0042] As a further explanation of the feeding of the vulcanizing machine, the frame 1 is provided with a feeding assembly 6.1, which includes an adsorption plate 6.2, a lifting module 6.3 for driving the adsorption plate to move up and down, a telescopic module 6.6 for driving the adsorption plate to move back and forth, and a horizontal moving module 6.4 for driving the adsorption plate 6.2 to move horizontally. The adsorption plate 6.2 is provided with a number of adsorption units 6.5.

[0043] After the vulcanizing machine completes the vulcanization of the silicone sheet, the horizontal moving module 6.4, the telescopic module 6.6, and the lifting module 6.3 can be used to drive the adsorption plate 6.2 to move up, down, left, and right. The adsorption unit 6.5 on the adsorption plate 6.2 adsorbs the vulcanized product, realizing automatic feeding. This allows for better integration of the vulcanizing machine, the feeding machine, and the open mill, achieving multi-machine linkage. No manual feeding or transfer is required, greatly improving production efficiency.

[0044] Furthermore, a movable lead screw 7.3 is mounted on the frame 1, and a sliding block 7.4 is mounted on the movable lead screw 7.3. The sliding block 7.4 is connected to the mounting platform 2. The movable lead screw 7.3 can drive the sliding block 7.4 to move, thereby adjusting the position of the discharge end of the molding die 5, so that the extruded silicone sheet can fall directly into the vulcanizing machine to achieve automatic feeding.

[0045] During the silicone sheet feeding process, the moving screw 7.3 will drive the sliding block 7.4 to move, so that the discharge end of the molding mold 5 reaches the designated position. After the silicone sheet falls onto the vulcanizing machine, the moving screw 7.3 will drive the sliding block 7.4 to retract. After vulcanization is completed, the unloading component 6.1 will take out the product from the vulcanizing machine, realizing multi-machine linkage to greatly improve production efficiency.

[0046] Example 2

[0047] like Figure 8 As shown, the difference between this embodiment and Embodiment 1 is that an adjusting plate 3.1 is inserted at the bottom of the discharge nozzle 1.2. The adjusting plate 3.1 moves up and down along the discharge trough 1.5 to adjust the diameter of the discharge trough 1.5. The diameter of the discharge trough 1.5 can be controlled by the adjusting plate 3.1 to meet the production needs of different sizes and models.

[0048] Furthermore, an adjusting screw 3.2 is inserted at the bottom of the discharge nozzle 1.2. The adjusting screw 3.2 is connected to the adjusting plate 3.1. When the adjusting screw 3.2 rotates, it drives the adjusting plate 3.1 to move up and down. When it is necessary to adjust the size of the discharge trough 1.5, the adjusting screw 3.2 can be rotated to make the adjusting plate 3.1 move up and down, thereby realizing the rapid adjustment of the diameter of the discharge trough 1.5.

[0049] Example 3

[0050] like Figure 9 As shown, the difference between this embodiment and Embodiment 1 is that the discharge plate 1.1 is provided with several mounting steps 5.1, and the mounting steps 5.1 are embedded with aperture control plates 5.2. The strip extrusion holes 1.4 are formed on the aperture control plates 5.2. Different aperture control plates 5.2 with different apertures can be replaced to cooperate with different mounting steps 5.1. Different aperture control plates 5.2 have different extrusion speeds and different characteristics.

[0051] Example 4

[0052] like Figure 10 , Figure 11 As shown, the difference between this embodiment and Embodiment 1 is that multiple aperture control plates 5.2 with different apertures are spaced apart along the insertion direction on the discharge plate 1.1. The aperture control plates 5.2 with different apertures can be respectively arranged opposite to the output end of the feeding tube 3 to form strip-shaped silicone strips with different outer diameters, which are not suitable for products with different performance.

[0053] Furthermore, an installation groove 5.3 is formed on the discharge plate 1.1, and a limiting post 5.4 is provided in the installation groove 5.3. A limiting hole 5.6 is formed on the discharge seat 4.1 for the limiting post 5.4 to be inserted, and an elastic element 5.5 is provided in the installation groove 5.3. One end of the elastic element 5.5 abuts against the installation groove 5.3, and the other end abuts against the limiting post 5.4, so that the limiting post 5.4 always has the tendency to extend out of the installation groove 5.3.

[0054] During the insertion of the discharge plate 1.1, once it reaches the designated position, the limiting post 5.4 will be inserted into the limiting hole 5.6 to ensure the accuracy and stability of the installation of the discharge plate 1.1.

[0055] Preferably, the limiting posts 5.4 are spaced apart on the discharge plate 1.1 and correspond to different aperture control pieces 5.2 respectively.

[0056] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
