[0026] Embodiment 1:

[0027] like Figures 1 to 4 As shown, the horizontal adjustment device of the heating plate 10 of the utility model includes: a base 1, on which a bottom plate 2 that can be vertically lifted and lowered is arranged, and a lifting component for controlling the bottom plate 2 to be lifted and lowered; the lifting component includes a screw sleeve 31 arranged on the bottom plate 2, a screw rod 32 rotatably mounted on the base 1 and passing through the screw sleeve 31, a first pulley 33 arranged at the bottom end of the screw rod 32, a servo motor 34 installed on the base 1 and a second pulley 35 arranged at the driving shaft end of the servo motor 34, and the first pulley 33 and the second pulley 35 are connected by a belt 36.

[0028] When the bottom plate 2 needs to be lifted or lowered on the base 1, the servo motor 34 drives the second pulley 35 to rotate, and the second pulley 35 drives the first pulley 33 to rotate through the belt 36. The first pulley 33 drives the screw 32 to rotate. The screw 32 is threadedly connected to the screw sleeve 31. When the screw 32 rotates, the screw sleeve 31 can drive the bottom plate 2 to be lifted or lowered on the screw 32. It has the characteristics of simple structure and stable lifting of the bottom plate 2. It should be noted that in order to prevent the bottom plate 2 from rotating synchronously with the screw 32, a light rod 37 is arranged on the base 1, and the light rod 37 passes through the bottom plate 2.

[0029] See also Figure 2There are two groups of adjustment components, which are respectively arranged on both sides of the bottom plate 2. The adjustment components are used to adjust the horizontal height of the side of the heating plate 10. Each group of adjustment components includes two adjustment rods and a support seat 41. The top surface of the support seat 41 is fixedly connected to the heating plate 10 by bolts.

[0030] See also Figure 1 , Figure 2 , Figure 4 The adjusting rod is configured on the bottom plate 2 in a liftable manner through an adjusting mechanism. A groove 42 is provided at the bottom of the support seat 41, and the adjusting rod is rotatably installed in the groove 42 through a rotating rod 43. In order to avoid the problem that the heating plate 10 is overheated and causes the product to expand, thereby reducing the fit between the product and the heating plate 10, the present application provides a waist-shaped hole 44 on the side of the support seat 41, and the rotating rod 43 is located in the waist-shaped hole 44, so as to realize the lateral movement of the support seat 41 relative to the adjusting rod, and then realize that the heating plate 10 can move laterally with the product, thereby ensuring the fit between the product and the heating plate 10 and improving the heating efficiency of the product.

[0031] See also Figure 2 There are four adjusting rods in total, namely the first adjusting rod 45, the second adjusting rod 46, the third adjusting rod 47 and the fourth adjusting rod 48; when the heating plate 10 is adjusted in the horizontal direction, the first adjusting rod 45 and the third adjusting rod 47 are controlled to rise or fall relative to the bottom plate 2, or the second adjusting rod 46 and the fourth adjusting rod 48 are controlled to rise or fall relative to the bottom plate 2, so that the two support seats 41 synchronously drive the heating plate 10 to tilt to one side, and adapt to products of different shapes, thereby improving the thermal fit between the heating plate 10 and the product, and improving the heating efficiency and the temperature uniformity of the product.

[0032] In one or more embodiments, the adjustment mechanism includes a lifting rod 51 and a lifting groove 52 opened on the base plate 2, a ring groove 511 for accommodating the adjustment rod is formed on the top of the lifting rod 51, an internal thread is opened on the inner wall of the lifting groove 52, and the outer peripheral side of the lifting rod 51 has an external thread matching the lifting groove 52.

[0033] See also Figure 2 , Figure 3 When the adjusting rod is lifted or lowered, the lifting rod 51 is rotated so that the lifting rod 51 can be lifted or lowered through the lifting groove 52 opened on the bottom plate 2. The bottom end of the adjusting rod is located in the annular groove 511 opened at the top of the lifting rod 51. During the lifting and lowering process of the lifting rod 51, the adjusting rod does not rotate. The lifting rod 51 rotates relative to the adjusting rod, thereby realizing the synchronous lifting and lowering of the first adjusting rod 45 and the third adjusting rod 47, or realizing the synchronous lifting and lowering of the second adjusting rod 46 and the fourth adjusting rod 48, which has the characteristics of high adjustment accuracy and convenient adjustment.

[0034] Embodiment 2:

[0035] As the second embodiment of the utility model, the components identical or corresponding to the first embodiment are marked with the same reference numerals as those of the first embodiment. The difference between the second embodiment and the first embodiment lies in the different structure of the adjustment mechanism for controlling the lifting and lowering of the adjustment rod.

[0036] In the second embodiment, the structure of the adjustment mechanism is a driving cylinder arranged on the bottom plate 2, and the extended shaft end of the driving cylinder is connected to the bottom of the adjustment rod.

[0037] When the adjusting rod is raised or lowered, the extended shaft end of the driving cylinder is extended or retracted to achieve the synchronous lifting of the first adjusting rod 45 and the third adjusting rod 47, or the synchronous lifting of the second adjusting rod 46 and the fourth adjusting rod 48, which has the characteristics of high degree of automation and accurate adjustment accuracy.
