Picture frame material cutting, uncovering and chamfering device

Abstract

The utility model provides a picture frame material cutting, uncovering and chamfering device which comprises a fixed table top and a pair of cutting, uncovering and chamfering mechanisms, and each cutting, uncovering and chamfering mechanism comprises a picture frame fixing mold, a side pressing assembly, an upper pressing assembly and a bottom pressing assembly. In the cutting, uncovering and chamfering mechanism, a side pressing assembly, an upper pressing assembly and a bottom pressing assembly are intensively arranged on the opposite face of a picture frame fixing mold and around the position above the picture frame fixing mold, and picture frame materials placed on the picture frame fixing mold are pressed and limited in the up-down direction and the left-right direction. Due to the fact that the clamping and positioning positions of all the assemblies on the picture frame are limited to the contact positions of the picture frame material to be cut and the picture frame fixing mold in a concentrated mode, the contact positions of the picture frame material to be cut and all the assemblies are short. Therefore, the to-be-cut picture frame material with the shorter cutting length can be positioned, clamped and cut, and the problem that automatic cutting of the picture frame with the shorter length size is difficult is solved.

Description

Technical Field

[0001] This utility model relates to the technical field of picture frame cutting equipment, specifically to a picture frame material cutting, opening, and chamfering device. Background Technology

[0002] The main functions of a picture frame are to protect the artwork, beautify the environment, and complement the subject. Specifically, the frame surrounds the image with its border structure, which not only helps to fix the artwork in place but also facilitates hanging and display, thus effectively protecting the artwork from damage.

[0003] A picture frame is assembled from four borders. During the manufacturing process, the ends of the four borders must first be chamfered to facilitate the subsequent assembly of adjacent borders. In existing technologies, the chamfering of the picture frame borders tends to be done using a high-efficiency picture frame corner cutting machine. This machine cuts both ends of the picture frame borders simultaneously. Since the borders need to be kept in a fixed position during cutting, multiple clamping and positioning mechanisms are required to restrict the freedom of movement of the picture frame borders and prevent them from wobbling during the cutting process. However, the existing picture frame corner cutting equipment has a relatively complex and not compact structure with multiple clamping and positioning mechanisms, making it difficult to automatically cut picture frame borders with shorter lengths (less than 300mm). Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a picture frame material cutting, opening and chamfering device to solve the problem that the existing picture frame corner cutting equipment has a complex and not compact structure of multiple clamping and positioning mechanisms, which makes it difficult to automatically cut picture frame edges with short length dimensions.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] This application provides a frame material cutting, opening, and beveling device, including a fixed platform and a pair of cutting, opening, and beveling mechanisms. The pair of cutting, opening, and beveling mechanisms are symmetrically arranged on the fixed platform. Each cutting, opening, and beveling mechanism includes:

[0007] A picture frame frame fixing mold is fixedly installed on the fixing platform. The picture frame material fixing mold is used to support the bottom of the picture frame frame to be cut and to limit one side of the picture frame frame to be cut.

[0008] A side-pressing component is installed on the opposite side of the fixed platform relative to the frame frame fixing mold. The side-pressing component is used to push the frame frame to be cut to the frame frame fixing mold for pressing.

[0009] The upper pressing component is located directly above the frame frame fixing mold. The upper pressing component is used to press the frame frame to be cut down and press it firmly onto the frame frame fixing mold.

[0010] The bottom pressing component is disposed above the frame frame fixing mold. The bottom pressing component is disposed on one side of the frame frame fixing mold and adjacent to the position of the upper pressing component. The bottom pressing component is used to press the bottom of the groove of the frame frame to be cut onto the frame frame fixing mold.

[0011] Furthermore, it also includes a cover opening assembly, which includes a cover opening cylinder and a cover opening side pressing head. The cover opening side pressing head is vertically slidably mounted on the frame frame fixing mold. The cover opening side pressing head is located adjacent to one side of the pressing assembly. The cover opening cylinder is connected to the cover opening side pressing head. The cover opening side pressing head is used to press one side of the groove of the frame frame to be cut onto the side pressing assembly.

[0012] Furthermore, the side pressure assembly includes a side pressure cylinder and a closing side pressure head. The side pressure cylinder is fixedly installed on the fixed platform. The piston rod of the side pressure cylinder is connected to the closing side pressure head. The closing side pressure head is used to push the frame edge to be cut to the frame edge fixing mold for pressing.

[0013] Furthermore, the pressing assembly includes an upper pressing cover cylinder and an upper pressing head. The piston rod of the upper pressing cover cylinder is connected to the upper pressing head, and the upper pressing head is used to press the frame edge to be cut down and press it firmly onto the frame edge fixing mold.

[0014] Furthermore, the bottom pressing assembly includes a bottom pressing cylinder and a bottom pressing block. The piston rod of the bottom pressing cylinder is connected to the bottom pressing block. The bottom pressing block is used to extend horizontally into the groove of the frame to be cut and press down to press the bottom of the groove onto the frame fixing mold.

[0015] Furthermore, it also includes a pressing cylinder fixing frame, which is fixedly installed on the fixing platform, and the upper pressing cylinder and the bottom pressing cylinder are respectively fixedly installed on the pressing cylinder fixing frame.

[0016] The beneficial effects of this utility model are as follows:

[0017] By employing the aforementioned frame material cutting and chamfering device, a pair of cutting and chamfering mechanisms are symmetrically arranged on the fixed platform. They are used to clamp and position both ends of the frame material. In each cutting and chamfering mechanism, the side pressing component, the upper pressing component, and the bottom pressing component are concentrated around the opposite and above positions of the frame frame fixing mold. They clamp and limit the frame material placed on the frame frame fixing mold in the up, down, left, and right directions. Since the clamping and positioning positions of each component are concentrated and limited to the contact position between the frame material to be cut and the frame frame fixing mold, and the contact length between the frame material to be cut and each component is relatively short, it is possible to position, clamp, and cut frame material with a shorter cutting length, thereby solving the problem of difficulty in automatically cutting frame frames with shorter dimensions.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0034] See appendix Figure 1 To be continued Figure 4 As shown, this embodiment provides a frame material cutting, opening, and chamfering device 10, including a fixed platform 20 and a pair of cutting, opening, and chamfering mechanisms 30. The pair of cutting, opening, and chamfering mechanisms 30 are symmetrically installed on the fixed platform 20. The pair of cutting, opening, and chamfering mechanisms 30 clamp and position the left and right ends of the frame 40 to be cut, respectively, to prevent the frame 40 to be cut from shaking during the cutting process.

[0035] See attached document Figure 2 and attached Figure 3 As shown, a cutting groove 21 is provided on the fixed table 20 near the position of each cutting and chamfering mechanism 30. The cutting groove 21 is used for the movement of the cutting saw blade to chamfer one end of the frame 40 to be cut, which is held on the cutting and chamfering mechanism 30.

[0036] See attached document Figure 4 and attached Figure 5 As shown, in this embodiment, the cutting and chamfering mechanism 30 includes a frame frame fixing mold 31, a side pressing component 32, an upper pressing component 33, and a bottom pressing component 34. The frame frame fixing mold 31 is fixedly installed on the fixed platform 20. The frame frame fixing mold 31 is used to support the bottom of the frame frame 40 to be cut and to limit one side of the frame frame 40 to be cut.

[0037] In this embodiment, refer to the appendix Figure 6 and attached Figure 7 As shown, the side pressing component 32, the upper pressing component 33, and the bottom pressing component 34 are concentrated around the opposite and above positions of the frame frame fixing mold 31, pressing and limiting the frame frame material placed on the frame frame fixing mold 31 in the up, down, left, and right directions. Since the clamping and positioning positions of each component are concentrated and limited to the position where the frame frame material to be cut contacts the frame frame fixing mold 31, and the length of the part of the frame frame material to be cut that contacts each component is relatively short, the frame frame material to be cut with a shorter cutting length can be positioned, clamped, and cut.

[0038] See attached document Figure 7 and attached Figure 8 As shown, in this embodiment, the frame fixing mold 31 includes a stepped support portion 311 and an abutment portion 312 extending from the support portion 311 toward one side inward. The bottom end of the frame 40 to be cut is placed horizontally on the support portion 311, and the support portion 311 provides upward support for the frame 40 to be cut placed thereon. The abutment portion 312 extends into the groove 41 of the frame 40 to be cut and abuts against the inner wall of the groove 41, forming a one-sided limit on the frame 40 to be cut (see attached figure). Figure 7 (As shown).

[0039] See attached document Figure 4 Appendix Figure 6 and appendix Figure 7 As shown, in this embodiment, the side pressing component 32 is installed on the fixed platform 20 on the opposite side of the frame frame fixing mold 31. For example, if the frame frame fixing mold 31 is installed on the left side of the fixed platform 20, then the side pressing component 32 is installed on the right side of the fixed platform 20. The two are arranged opposite to each other. The side pressing component 32 is used to push the frame frame 40 to be cut to the frame frame fixing mold 31 for pressing.

[0040] See attached document Figure 4 and attached Figure 6 As shown, in this embodiment, the side pressure assembly 32 includes a side pressure cylinder 321 and a closing side pressure head 322. The side pressure cylinder 321 is fixedly installed on the fixed platform 20. The piston rod of the side pressure cylinder 321 is connected to the closing side pressure head 322. The closing side pressure head 322 is used to push the frame 40 to be cut to the frame fixing mold 31 for pressing.

[0041] See attached document Figure 7As shown, when the frame frame 40 to be cut is placed on the frame frame fixing mold 31, the frame frame 40 to be cut is placed on the outside of the frame frame fixing mold 31. The frame frame 40 to be cut also needs to be pushed by the side pressure component 32, that is, the piston rod of the side pressure cylinder 321 drives the closing side pressure head 322 to extend to one side of the frame frame fixing mold 31. The closing side pressure head 322 pushes the frame frame 40 to be cut horizontally to one side of the frame frame fixing mold 31, so that the frame frame 40 to be cut is pressed tightly against the frame frame fixing mold 31.

[0042] See attached document Figure 4 Appendix Figure 6 and appendix Figure 7 As shown, in this embodiment, the upper pressing component 33 is disposed directly above the frame frame fixing mold 31. The upper pressing component 33 is used to press down and clamp the frame frame 40 to be cut onto the frame frame fixing mold 31.

[0043] Specifically, the pressing assembly 33 includes an upper pressing cylinder 331 and an upper pressing head 332. The piston rod of the upper pressing cylinder 331 is connected to the upper pressing head 332, which is used to press down and clamp the frame edge 40 to be cut onto the frame edge fixing mold 31. (See attached diagram.) Figure 6 and attached Figure 7 As shown, the upper pressure head 332 includes an upper pressure head body and an upper pressure block 333 extending vertically downward from the middle of the bottom end face of the upper pressure head body. The upper pressure block 333 and the left and right sides of the bottom end face of the upper pressure head body respectively form notches 334. (See attached diagram.) Figure 7 As shown, when the upper pressure head presses down on the top surface of the frame 40 to be cut, the closed-side pressure head 322 extends into the notch 334 formed by the upper pressure block 333 and the bottom surface of the upper pressure head body. Through the above-mentioned structural arrangement of the upper pressure head, the closed-side pressure head 322 and the upper pressure head can be concentrated on the outer peripheral surface of a certain position of the frame 40 to be cut. The structure is more compact, avoiding the problem of excessive contact length with the frame 40 to be cut due to the closed-side pressure head 322 and the upper pressure head being clamped on the surface of the frame 40 to be cut at different positions, which is not conducive to cutting small-sized frame 40 to be cut.

[0044] See attached document Figure 4 and attached Figure 6 As shown, in this embodiment, the bottom pressing component 34 is disposed above the frame frame fixing mold 31. The bottom pressing component 34 is disposed on one side of the frame frame fixing mold 31 and adjacent to the position of the upper pressing component 33. The bottom pressing component 34 is used to press the bottom of the groove 41 of the frame frame 40 to be cut onto the frame frame fixing mold 31.

[0045] See attached document Figure 10As shown, specifically, the bottom pressing assembly 34 includes a bottom pressing cylinder 341 and a bottom pressing block 342. The piston rod of the bottom pressing cylinder 341 is connected to the bottom pressing block 342. The bottom pressing block 342 is used to extend horizontally into the groove 41 of the frame 40 to be cut and press down to press the bottom of the groove onto the frame fixing mold 31.

[0046] See attached document Figure 6 and attached Figure 10 As shown, in this embodiment, the pressing block 342 is used to press the bottom of the groove of the frame 40 to be cut. Therefore, before the side pressing component 32 pushes the frame 40 to be cut towards the frame fixing mold 31, the pressing cylinder 341 pushes the pressing block 342 downward. When the side pressing component 32 pushes the frame 40 to be cut towards the frame fixing mold 31, the groove 41 of the frame 40 to be cut will move towards the pressing block 342, so that the pressing block 342 gradually extends horizontally into the groove 41 of the frame 40 to be cut. After the frame 40 to be cut moves into place towards the frame fixing mold 31, the pressing cylinder 341 drives the pressing block 342 downward, so that the bottom end face of the pressing block 342 presses against the inner wall of the groove bottom of the frame 40 to be cut.

[0047] See attached document Figure 4 Appendix Figure 5 and appendix Figure 9 As shown, it also includes a cover opening assembly 35, which includes a cover opening cylinder 351 and a cover opening side pressing head 352. The cover opening side pressing head 352 is vertically slidably mounted on the frame frame fixing mold 31. The cover opening side pressing head 352 is located near one side of the pressing bottom assembly 34. The cover opening cylinder 351 is connected to the cover opening side pressing head 352. The cover opening side pressing head 352 is used to press one side of the groove 41 of the frame frame 40 to be cut onto the side pressing assembly 32.

[0048] See attached document Figure 7 To be continued Figure 9 As shown, in this embodiment, the frame frame fixing mold 31 has a vertically penetrating sliding hole 313. The opening side pressing head 352 passes vertically through the sliding hole 313. The bottom end of the opening side pressing head 352 is connected to the piston rod of the opening cylinder 351. The top end of the opening side pressing head 352 can be horizontally inserted into the groove 41 of the frame frame 40 to be cut, so as to press one side of the groove 41 of the frame frame 40 to be cut against the side pressing component 32.

[0049] See attached document Figure 4 As shown, the fixed platform 20 is also equipped with a pressing cylinder fixing frame 36, and the upper pressing cylinder 331 and the bottom pressing cylinder 341 are respectively fixedly installed on the left and right sides of the pressing cylinder fixing frame 36.

[0050] To better understand the frame material cutting, opening, and chamfering device in this embodiment, its working principle is briefly explained below:

[0051] See attached document Figure 1 and attached Figure 3 As shown, the frame to be cut is placed horizontally on the frame frame fixing mold 31 (with the groove 41 side of the frame to be cut facing the frame frame fixing mold 31). Then, the bottom pressing cylinder 341 pushes the bottom pressing block 342 downward, and the cover opening cylinder 351 pushes the cover opening side pressing head 352 upward, so that the bottom pressing block 342 and the cover opening side pressing head 352 are at the same horizontal height (so that they can be horizontally inserted into the groove 41 of the frame to be cut). Next, the piston rod of the side pressing cylinder 321 drives the cover closing side pressing head 322 to extend towards the frame frame fixing mold 31. The cover closing side pressing head 322 pushes the frame to be cut 40 horizontally towards the frame frame fixing mold 31, so that the frame to be cut 40 is pressed tightly against the frame frame fixing mold 31. During the process of the frame to be cut 40 being pressed tightly against the frame frame fixing mold 31, the bottom pressing block 342 and the cover opening side... The pressing head 352 gradually extends into the groove 41 of the frame edge 40 to be cut. The pressing head 352 on the open side comes into contact with the groove 41 of the frame edge 40 to be cut, pressing one side of the groove 41 of the frame edge 40 to be cut against the side pressing component 32. After the frame edge to be cut moves into place towards the frame edge fixing mold 31, the bottom pressing cylinder 341 drives the bottom pressing block 342 to move downward, so that the bottom end face of the bottom pressing block 342 presses against the frame edge to be cut. The inner wall of the groove bottom of the frame frame 40 is cut; then, the piston rod of the upper pressure cylinder 331 drives the upper pressure head to move down, and the upper pressure head contacts and presses down on the top surface of the frame frame 40 to be cut, so as to press the frame frame 40 to be cut down and press it firmly on the frame frame fixing mold 31; finally, the cutting saw blades installed in the cutting grooves 21 on both sides of the fixed table 20 move along the cutting grooves 21 to simultaneously chamfer the left and right ends of the frame frame 40 to be cut.

[0052] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
