Description

Technical Field

[0001] The present application relates to the field of automatic unloading machines, and in particular to an automatic unloading device for a preforming machine. Background Art

[0002] Preforming is to place a mixture of PTFE and lubricating oil in a tubular device and pre-press it into a cylindrical blank under a certain pressure. This is to remove the air between the resin particles after adding the lubricating oil, so that the resin particles are tightly combined, and finally obtain a mechanically acceptable preform for paste extrusion. In the preforming process of the product, a preforming machine is required. By adding materials to the preforming machine, a cavity is set in the preforming machine, and the materials are preformed in the cavity by pressurizing the materials. The processed products are then taken out of the preforming machine and subsequently refined.

[0003] In the process of loading materials, in order to reduce the labor intensity and reduce the pollution caused by contact between materials and hands, automatic loading and unloading devices are usually used. For unloading devices, conveyor belts are mostly used, and they are semi-automatic, that is, workers are required to take the materials off the preformer and move them to the conveyor belt. Although some labor intensity is reduced, there is still a link of manual handling. Utility Model Content

[0030] The following is combined with Figure 1-2 This application is described in further detail.

[0031] This embodiment discloses an automatic unloading device for a preforming machine, referring to Figure 1 and Figure 2 The automatic unloading device of the preforming machine includes a hooking mechanism 1 and a conveying mechanism 2. The hooking mechanism 1 can remove the material from the preforming machine 4 and move the material to the conveying mechanism 2, and the conveying mechanism 2 then transports the logistics, thereby realizing the fully automated transportation of the material.

[0032] The hooking mechanism 1 includes a slide plate 11, a hook 12 and a driver 13. One end of the slide plate 11 is connected to the preformer 4, and the other end is tilted downward to form a certain slope, so that the material can slide downward under the action of gravity. The hook 12 is installed on the side of the slide plate 11 facing the preformer 4, and is used to hook the material. The driver 13 is set as a cylinder, and the piston rod of the cylinder is connected to the hook 12. The hook 12 is driven to move in the horizontal direction through the telescopic movement of the cylinder, so that the material is hooked from the preformer 4 and pushed to the conveying mechanism 2.

[0033] Furthermore, the hook 12 is shaped as an arc structure, with its concave surface facing the material. This structure enables the hook 12 to better fit the surface of the material when hooking the material, thereby improving the hooking success rate and reducing material damage.

[0034] A retaining tube 16 is also provided inside the hook claw 12. The retaining tube 16 can be sleeved on the material. The hook claw 12 hooks the material by hooking the retaining tube 16, so as to avoid the hook claw 12 directly hooking the material and causing damage to the material.

[0035] In addition, the driver 13 is arranged on one side of the slide 11, and the baffle 14 is arranged on the other side of the slide 11, and a passage for the movement of materials is formed between the driver 13 and the baffle 14. The position setting of the driver 13 and the setting of the baffle 14 prevent the materials from sliding off the two sides of the slide 11 during the sliding process.

[0036] At the same time, a plurality of rollers 15 are additionally provided on the slide plate 11. These rollers 15 can reduce the moving resistance of the material in the channel, so that the material can slide onto the conveying mechanism 2 more smoothly.

[0037] The conveying mechanism 2 includes a sprocket 21, a leaf chain 22 and a pallet 23. The sprocket 21 is driven to rotate by a motor, and the leaf chain 22 is wound around the sprocket 21 to form a closed circulation path. The pallet 23 is fixed on the leaf chain 22 and moves in a circulation with the leaf chain 22. The pallet 23 is used to carry the material dropped from the hook 12 and transport it to a designated location.

[0038] In this embodiment, the conveying mechanism 2 is disposed below the end of the slide 11 away from the preforming machine 4, so that the material can move from the slide 11 to the support plate 23 under the action of its own gravity.

[0039] The support plate 23 is configured to have a structure with sufficient load-bearing capacity to ensure that the material falling from the hook 12 can be stably carried. The support plate 23 is composed of a plurality of support plates 231 arranged in parallel at intervals, each support plate 231 is fixedly connected to the plate chain 22, and a reinforcing rib 232 is arranged below the support plate 231. A through slot for the support plate 23 to pass through is provided on the slide plate 11 to ensure the circulation of the support plate 23.

[0040] At the same time, the surface of the support plate 23 is also provided with anti-skid patterns to increase the friction between the support plate 23 and the material to prevent the material from sliding or rolling during transportation.

[0041] The present embodiment is further improved in that a tilting portion 233 is provided at the edge of the support plate 23. The tilting portion 233 can limit the material to prevent the material from sliding or rolling off the support plate 23 during transportation.

[0042] The height and shape of the tilting portion 233 are designed according to the characteristics of the material and the transportation requirements. By reasonably setting the tilting portion 233, the stability and safety of the material during transportation can be ensured, and the reliability of the unloading device can be improved.

[0043] In the embodiment of the present application, the slide plate 11 and the sprocket 21 are both installed on the ground through a bracket to ensure smooth operation.

[0044] This embodiment further adds a material box 3. The material box 3 is located at the output end of the conveying mechanism 2 and is used to collect materials dropped from the pallet 23. The material box 3 is provided with a through slot for the pallet 23 to pass through, so that the pallet 23 can smoothly convey the materials into the material box 3.

[0045] The design of the material box 3 takes into account the characteristics and collection requirements of the materials, and its internal space is large enough to accommodate a sufficient amount of materials. At the same time, the material and structure of the material box 3 also have sufficient strength and durability to ensure long-term stable use.

[0046] By adding the material box 3, the materials output by the unloading device can be conveniently collected and managed, thereby improving production efficiency and operating convenience.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
