[0026] The following is a further detailed description of the present invention in conjunction with specific embodiments:

[0027] For ease of understanding, first explain the application scenario of this application. The replacement chambers in the kiln are arranged in a processing order, and the products are transferred and transported between the replacement chambers to complete the processing. Figure 1 There are gates between adjacent replacement chambers, so that the flow of products is not continuous. Usually, a driving mechanism is configured at the corresponding station of each replacement chamber, and the driving mechanism usually adopts a telescopic cylinder, which requires sufficient installation and working space to push the pallet carrying the products to move to the next station. Figure 1 In the middle, the upstream conveying route turns and changes direction. The space reserved around the station can meet the space requirements of the cylinder, but the three stations D, D, and E are connected into a longer station line, which cannot meet the space requirements of the three cylinders. Therefore, this application adopts the hook plate method in the longer station line area to realize the transmission of the pallet and the product. Figure 2 Compared with the existing technology ( Figure 1 As shown), the present application adopts a hook plate to realize transmission, which can omit a part of the station equipment (station D'), making the overall layout of the equipment more compact, saving cost and installation space.

[0028] like Figure 3 As shown, a push plate back-pull mechanism for a kiln replacement chamber box includes a support plate 3 on a work station line and a hook plate member 1, a horizontal driving member 4, and a movable seat 2 arranged at the bottom of the work station line.

[0029] Refer to the attached Figure 4 The product to be processed is placed on the pallet 3 and moves with the pallet 3. The hook plate 1 is installed on the top of the movable base 2 and is supported by the fixed track 5. The fixed track 5 is set along the top linear work station line; the driving end of the horizontal drive member 4 is connected to the movable base 2 through the positioning plate 6. Driven by the horizontal drive member 4, the movable base 2 moves back and forth along the fixed track 5, thereby transporting the product of the top hook plate 1 to the next work station and returning to the initial position to wait for the next product 8 to be transported.

[0030] Specifically, the hook plate member 1 includes a hook plate 11, a connecting portion 12, and a posture driving portion 13. The connecting portion 12 is fixedly mounted on the movable base 2, the posture driving portion 13 is fixedly mounted at the rear end of the connecting portion 12, and a receiving cavity 20 is provided at the head end of the connecting portion 12. The hook plate 11 is rotatably mounted on the side wall of the receiving cavity 20.

[0031] In a specific implementation, the posture driving part 13 can be set as a controller (PLC controller), the hook plate 11 is fixed by an electric shaft, and the controller controls the electric shaft to rotate, thereby driving the hook plate 11 to rotate to change the working posture.

[0032] The shape of the hook plate 11 can be adjusted according to the contour shape of the support plate 3. Figure 4 As shown, the support plate 8 is a rectangular parallelepiped, and correspondingly, the hook plate 11 is set to an L shape, and the semi-enclosed inner wall surface is in contact with the side wall of the support plate 3. Figure 5 As shown, in the working state, the hook arm 111 and the handle arm 112 of the hook plate 11 both maintain an upright posture.

[0033] After the product 8 is transported to the next station, refer to the attached Figure 7 As shown, the handle arm 112 rotates around the end fixed point, driving the hook arm 111 to rotate downward, so that the top of the hook arm 111 is lower than the bottom surface of the support plate 3, so as to release the support plate 3, and then keep it as shown in the attached figure. Figure 8 Waiting posture.

[0034] Furthermore, a pin plate 7 is provided in the accommodating cavity 20, the bottom end of the pin plate 7 is fixed to the bottom surface of the accommodating cavity 20, and the top end of the pin plate 7 is fixed to the hook plate 11; Figure 5 Combined with attachment Figure 8 As shown, both ends of the pin plate 7 can rotate around a fixed point to adapt to the posture adjustment of the hook plate 11.

[0035] Refer to the attached Figure 6 As shown in the partial view in the middle, the horizontal driving member 4 adopts a telescopic cylinder, which is parallel to the upper support plate 3 or the work station line and is arranged in parallel up and down. The driving end of the telescopic cylinder is connected to the movable seat 2 through the positioning plate 6. By changing the length, thickness and position orientation of the positioning plate 6, the relative position of the telescopic cylinder and the movable seat 2 can be changed, and then more horizontal driving members can be installed in a limited space. Figure 3 As shown, the two moving seats 2 move along the same fixed track 5, and the two horizontal driving members 4 at the bottom are staggered.

[0036] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly, and they are not intended to limit the scope of protection of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes that fall within the meaning and scope of the equivalent elements of the claims are included in the present invention.
