Description

Technical Field

[0001] This utility model relates to the field of tunnel kiln feeding technology, specifically a feeding device for a tunnel kiln. Background Technology

[0002] A tunnel kiln is a kiln similar to a tunnel, constructed from refractory, insulation, and building materials and containing kiln cars and other transport vehicles. It is a modern, continuous firing thermal equipment, widely used in the firing of ceramic products, and also applied in metallurgical industries such as abrasives.

[0003] After the raw tea is finished in the tunnel kiln, the finished ceramic products need to be unloaded from the kiln car. Since the temperature of the freshly produced ceramic products is high, it is difficult to unload them manually. If they are to be unloaded manually after they have cooled naturally, it will delay the production progress. Therefore, a material unloading device for tunnel kilns is proposed to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] The purpose of this invention is to solve the problem that the temperature of freshly produced ceramic products is high, making it difficult to unload them manually. If they are left to cool naturally before being unloaded manually, it would delay the production schedule. Therefore, this invention proposes a material unloading device for tunnel kilns.

[0006] (II) Technical Solution

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0008] A material feeding device for a tunnel kiln includes a frame, a transverse moving component is provided at the top of the frame, a longitudinal moving component is provided on the transverse moving component, a vertical moving component is provided on the longitudinal moving component, and a clamping component for clamping a material rack is provided on the vertical moving component.

[0009] The vertical moving component includes a base. The top end of the vertical moving component is fixedly connected to the base. The right end of the base is fixedly connected to three second sliders. The right ends of the three second sliders are slidably connected to a second slide rail. The right end of the second slide rail is fixedly connected to a vertical moving seat. The rear end of the vertical moving seat is fixedly connected to a rack. The base is fixedly connected to a vertical driving motor. The output end of the vertical driving motor is fixedly connected to a gear that meshes with the rack.

[0010] The clamping assembly includes a connecting plate, the bottom end of the upper and lower movable seat is fixedly connected to the connecting plate, the bottom end of the connecting plate is fixedly connected to a bidirectional cylinder, and the outer sides of the two output ends of the bidirectional cylinder are fixedly connected to grippers.

[0011] Based on the above technical solution, the present invention can be further improved as follows.

[0012] Preferably, the lateral movement component includes a first slide rail, two first slide rails are fixedly connected to the top of the frame, three first sliders are slidably connected to the top of each of the two first slide rails, the tops of the six first sliders are fixedly connected to the lateral movement seat, a lateral drive motor is fixedly connected to the rear end of the frame, a pulley transmission mechanism is fixedly connected to the outer side of the output end of the lateral drive motor, a receiving seat is fixedly connected to the rear end of the frame, the pulley transmission mechanism is rotatably connected to the inner side of the receiving seat, and the belt of the pulley transmission mechanism is fixedly connected to the rear end of the lateral movement seat.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0015] This invention utilizes a horizontal moving component, a vertical moving component, a second slider, a second slide rail, an upper and lower moving seat, a rack, an upper and lower drive motor, gears, a bidirectional cylinder, and grippers. The horizontal and vertical moving components are controlled until the gripping component moves directly above the material rack. Then, the upper and lower drive motors are activated, causing the gears to rotate and the rack to move downwards. This causes the upper and lower moving seat to move downwards. At this point, the second slide rail slides downwards along the right ends of the three second sliders, positioning the two grippers precisely on the left and right sides of the material rack. Finally, the bidirectional cylinders are activated, retracting their two output ends until the two grippers clamp the material rack. Compared to existing technologies, this mechanical gripping of the material rack eliminates the need for manual unloading after cooling. Attached Figure Description

[0021] 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.

[0022] In the embodiments, by Figure 1-4 A material feeding device for a tunnel kiln is provided, comprising a frame 1, a transverse moving component 2 is provided at the top of the frame 1, a longitudinal moving component 3 is provided on the transverse moving component 2, a vertical moving component 4 is provided on the longitudinal moving component 3, and a clamping component 5 for clamping the material rack is provided on the vertical moving component 4.

[0023] The vertical moving component 4 includes a base 41. The top end of the vertical moving component 3 is fixedly connected to the base 41. Three second sliders 42 are fixedly connected to the right end of the base 41. The right ends of the three second sliders 42 are slidably connected to the second slide rail 43. The right end of the second slide rail 43 is fixedly connected to the vertical moving seat 44. The rear end of the vertical moving seat 44 is fixedly connected to the rack 45. The base 41 is fixedly connected to the vertical driving motor 46. The output end of the vertical driving motor 46 is fixedly connected to the gear 47 that meshes with the rack 45.

[0024] The clamping assembly 5 includes a connecting plate 51. The bottom end of the upper and lower movable seat 44 is fixedly connected to the connecting plate 51. The bottom end of the connecting plate 51 is fixedly connected to a bidirectional cylinder 52. The two output ends of the bidirectional cylinder 52 are both fixedly connected to grippers 53.

[0025] With the above settings, the up-and-down drive motor 46 is a servo motor. When the kiln car leaves the tunnel kiln and arrives below the clamping assembly 5 along the external track, it controls the horizontal movement assembly 2 and the vertical movement assembly 3 until the clamping assembly 5 moves directly above the material rack (which contains fired ceramic products). Then, the up-and-down drive motor 46 is activated, driving the gear 47 to rotate, which in turn drives the rack 45 to move downwards. This causes the up-and-down moving seat 44 to move downwards. At this time, the second slide rail 43 slides downwards along the right end of the three second sliders 42, so that the two grippers 53 are exactly located on the left and right sides of the material rack. Then, the bidirectional cylinder 52 is activated. The two output ends of the bidirectional cylinder 52 are retracted until the two grippers 53 clamp the material rack. Then, the up-down drive motor 46 reverses, the up-down moving seat 44 moves upward, and the two grippers 53 move the material rack upward. Then, the lateral moving component 2 and the longitudinal moving component 3 are controlled until the material rack is directly above the conveyor belt. Then, the up-down drive motor 46 is controlled to rotate forward again, the up-down moving seat 44 moves downward, and the two grippers 53 move the material rack downward until the material rack contacts the conveyor belt. Then, the two output ends of the bidirectional cylinder 52 are controlled to push out until the two grippers 53 no longer clamp the material rack. Finally, the conveyor belt is started to transport the material rack to the designated position.

[0026] Reference Figure 1-4 The transverse movement component 2 includes a first slide rail 21. Two first slide rails 21 are fixedly connected to the top of the frame 1. Three first sliders 22 are slidably connected to the top of each of the two first slide rails 21. The tops of the six first sliders 22 are fixedly connected to the transverse movement seat 23. A transverse drive motor 24 is fixedly connected to the rear end of the frame 1. A belt pulley transmission mechanism 25 is fixedly connected to the outer side of the output end of the transverse drive motor 24. A receiving seat 26 is fixedly connected to the rear end of the frame 1. The belt pulley transmission mechanism 25 is rotatably connected to the inner side of the receiving seat 26. The belt of the belt pulley transmission mechanism 25 is fixedly connected to the rear end of the transverse movement seat 23.

[0027] With the above structural setup, the horizontal drive motor 24 is a servo motor. When the horizontal drive motor 24 is started, it drives the belt pulley transmission mechanism 25 to move. Since the belt of the belt pulley transmission mechanism 25 is fixedly connected to the rear end of the horizontal moving seat 23, the horizontal moving seat 23 can move laterally, thereby changing the position of the clamping component 5. At this time, the six first sliders 22 slide laterally along the top of the two first slide rails 21 respectively. It should be noted that the structure used by the longitudinal moving component 3 is the same as that of the horizontal moving component 2, and the working principle is also the same, so it will not be described again.

[0028] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
