Description

Technical Field

[0001] This invention relates to the field of pit furnace technology, and more particularly to a pit furnace with an automatic feeding mechanism. Background Technology

[0002] Pit furnaces are vertical heating devices widely used in metal heat treatment, ceramic sintering, and other fields. The furnace body is typically buried deep in the ground or within a support structure, and materials must be loaded vertically from the furnace opening. Traditional pit furnace loading methods rely heavily on manual operation or simple hoisting equipment. Manual loading is slow, especially for batches, heavy materials, or high-temperature materials, resulting in long operation cycles and impacting overall production efficiency. Inaccurate material placement within the furnace affects the uniformity of heat treatment and can even cause materials to collide with the furnace walls. Repetitive handling operations place high demands on the physical strength of operators, easily leading to fatigue. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pit furnace with an automatic feeding mechanism.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A pit furnace with an automatic feeding mechanism includes a support frame, a furnace body is disposed inside the support frame, a feeding unit is disposed on the top of the support frame and above the furnace body, the feeding unit includes a support frame symmetrically disposed on the top of the support frame, a first sliding component is disposed on the support frame, a second sliding component is slidably coupled to the first sliding component, a clamping mounting frame is slidably coupled to the second sliding component, and a clamping unit for clamping materials is disposed at the bottom of the clamping mounting frame; The clamping unit includes multiple slide rails evenly arranged at the bottom of the clamping mounting frame. Each slide rail is slidably fitted with a sliding mounting plate, and each sliding mounting plate is provided with a clamping block for clamping materials. A synchronous drive assembly is provided at the bottom of the clamping mounting frame. The synchronous drive assembly includes a drive disk for driving the multiple sliding mounting plates to move synchronously. Multiple guide grooves for pushing single rod bearings are evenly arranged on the drive disk.

[0005] In addition, a preferred structure is that a feeding platform is provided on one side of the upper surface of the support, and multiple vertically arranged limiting posts for feeding are evenly arranged on the upper surface of the feeding platform.

[0006] Furthermore, in a preferred configuration, the top of the support frame is provided with a horizontal mounting plate for mounting the first sliding component. The first sliding component includes a first lead screw motor assembly horizontally mounted on the mounting plate, and first guide rails for sliding of the second sliding component are symmetrically arranged on the upper and lower sides of the first lead screw motor assembly.

[0007] Furthermore, in a preferred configuration, the second sliding assembly includes a sliding seat that slides on the first guide rail, a mounting frame is vertically mounted at the bottom of the sliding seat, a second lead screw motor assembly is vertically mounted on the mounting frame, and second guide rails for vertically slidingly clamping the mounting frame are symmetrically mounted on both sides of the second lead screw motor assembly.

[0008] Furthermore, in a preferred configuration, the clamping mounting bracket includes a sliding plate that slides on the second guide rail, a slide rail mounting plate for mounting the slide rail is provided at the bottom of the sliding plate, and a motor mounting plate is provided above the slide rail mounting plate.

[0009] Furthermore, in a preferred configuration, the synchronous drive assembly includes a motor unit mounted on a motor mounting plate, with the bottom output shaft of the motor unit connected to the center of the drive disk, and a slider for mounting the sliding mounting plate slidably fitted on the slide rail.

[0010] Furthermore, in a preferred configuration, a single-rod bearing is rotatably mounted on the upper surface of one end of the sliding mounting plate. The single-rod bearing is used for sliding engagement within a guide groove, and the other end of the sliding mounting plate away from the single-rod bearing is provided with a mounting hole for mounting a clamping block.

[0011] In addition, a preferred structure is that the clamping block is symmetrically provided with through holes, and the bottom of the clamping block is provided with a clamping convex surface for clamping materials.

[0012] The beneficial effects of this invention are as follows: This invention realizes the automatic grabbing, translation and dropping of materials through the feeding unit, eliminating the need for manual approach to the furnace opening, significantly reducing labor intensity and safety hazards. It is particularly suitable for feeding high-temperature and heavy materials. Through the synchronous drive assembly, the drive disc and guide slide groove cooperate with the single rod bearing to realize the synchronous movement of multiple sliding mounting plates, thereby enabling all clamping blocks to clamp or release synchronously, avoiding material deviation or falling off. The clamping convex surface at the bottom of the clamping block increases the friction force. The sliding fit structure between the slide rail and the sliding mounting plate can adjust the clamping distance according to the material size, making it suitable for various workpieces such as discs and rings.

Detailed Implementation

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0016] Reference Figure 1-9 A pit furnace with an automatic feeding mechanism includes a support frame 01, a furnace body 02 inside the support frame 01, a feeding unit 05 on the top of the support frame 01 and above the furnace body 02, the feeding unit 05 including a support frame 1 symmetrically arranged on the top of the support frame 01, a first sliding component 2 on the support frame 1, a second sliding component 3 slidably fitted on the first sliding component 2, a clamping mounting frame 4 slidably fitted on the second sliding component 3, a clamping unit 06 for clamping materials at the bottom of the clamping mounting frame 4, the clamping unit 06 including multiple slide rails 6 evenly arranged at the bottom of the clamping mounting frame 4, each slide rail 6 having a sliding mounting plate 7 slidably fitted on it, each sliding mounting plate 7 having a clamping block 8 for clamping materials, a synchronous drive component 5 at the bottom of the clamping mounting frame 4, the synchronous drive component 5 including a drive disk 52 for driving the multiple sliding mounting plates 7 to move synchronously, and multiple guide grooves 53 for pushing single rod bearings 71 evenly arranged on the drive disk 52.

[0017] Among them, a feeding platform 03 is provided on one side of the upper surface of the bracket 01. Multiple feeding limit posts 04 are evenly arranged vertically on the upper surface of the feeding platform 03 for feeding. The feeding limit posts 04 are used to stack multiple disc-shaped workpieces.

[0018] In addition, the top of the support frame 1 is horizontally provided with a mounting plate 11 for installing the first sliding component 2. The first sliding component 2 includes a first lead screw motor assembly 21 horizontally provided on the mounting plate 11. The first lead screw motor assembly 21 is symmetrically provided with first guide rails 22 for sliding the second sliding component 3 on its upper and lower sides. The second sliding component 3 includes a sliding seat 31 that is slidably engaged on the first guide rail 22. The bottom of the sliding seat 31 is vertically provided with a mounting frame 32. The mounting frame 32 is vertically provided with a second lead screw motor assembly 33. The second lead screw motor assembly 33 is vertically symmetrically provided with second guide rails 34 on both sides for vertically slidingly engaging the mounting frame 4.

[0019] Meanwhile, the clamping mounting bracket 4 includes a sliding plate 41 that slides on the second guide rail 34. The bottom of the sliding plate 41 is provided with a slide rail mounting plate 43 for mounting the slide rail 6. The top of the slide rail mounting plate 43 is provided with a motor mounting plate 42. The synchronous drive assembly 5 includes a motor assembly 51 mounted on the motor mounting plate 42. The bottom output shaft of the motor assembly 51 is connected to the middle of the drive disk 52. A slider 61 for mounting the sliding mounting plate 7 slides on the slide rail 6. The slider 61 is used to realize the displacement of the sliding mounting plate 7.

[0020] In addition, a single rod bearing 71 is rotatably mounted on the upper surface of one end of the sliding mounting plate 7. The single rod bearing 71 is used to slide in the guide groove 53. The other end of the sliding mounting plate 7 away from the single rod bearing 71 is provided with a mounting hole 72 for mounting the clamping block 8. The clamping block 8 is symmetrically provided with through holes 81. The bottom of the clamping block 8 is provided with a clamping protrusion 82 for clamping materials. The clamping protrusion 82 is used to clamp materials.

[0021] In this embodiment, when the disc-shaped material is moved into the pit furnace, there is no need for manual feeding. The feeding unit 05 can automatically feed the material. The disc-shaped material is placed horizontally between the limiting columns 04. During feeding, the first lead screw motor group 21 drives the sliding seat 31 to move laterally on the first guide rail 22, thereby driving the clamping unit 06 to move above the limiting column 04. The second lead screw motor group 33 drives the sliding plate 41 to move, thereby controlling the clamping unit 06 to descend to a suitable height to clamp the workpiece.

[0022] The motor unit 51 drives the drive disk 52 to rotate, thereby controlling the guide slide 53 to drive the single rod bearing 71 to move. The single rod bearing 71 pushes the sliding mounting plate 7 to move on the slide rail 6, so that the four clamping blocks 8 can contract and disperse synchronously, thereby achieving synchronous clamping of the disc-shaped workpiece. The clamping convex surface 82 facilitates the increase of friction, thereby preventing the disc-shaped workpiece from falling.

[0023] The second lead screw motor 33 drives the sliding plate 41 to move above the opened pit furnace. The second lead screw motor 33 controls the sliding plate 41 to descend, thereby moving the clamping unit 06 into the pit furnace for feeding. When the clamping unit 06 descends to a suitable height, the motor 51 is controlled to rotate, thereby driving the drive plate 52 to reset. The guide groove 53 causes the single rod bearings 71 to move in a dispersed manner, thereby allowing the clamping block 8 to put the disc-shaped material down into the pit furnace for feeding.

[0024] In this invention, the feeding unit 05 enables automatic material grabbing, translation, and dropping, eliminating the need for manual approach to the furnace opening and significantly reducing labor intensity and safety hazards. It is particularly suitable for feeding high-temperature and heavy materials. Through the synchronous drive assembly 5, the drive disc 52 and guide slide 53 cooperate with the single rod bearing 71 to realize the synchronous movement of multiple sliding mounting plates 7, thereby enabling all clamping blocks 8 to clamp or release synchronously, preventing material from tilting or falling off. The clamping convex surface 82 at the bottom of the clamping block 8 increases friction. The sliding fit structure between the slide rail 6 and the sliding mounting plate 7 can adjust the clamping distance according to the material size, making it suitable for various workpieces such as discs and rings.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
